Technical Field

The invention relates to the technical field of automobile glue supply, in particular to an automobile glue supply control device and a control method.

Background

In the existing automobile production and processing process, gluing equipment is often needed, and is used for injecting colloidal fluid (glue stock) to a working surface or some small gaps; when in use, the gluing equipment is also connected with a glue supply control device, and the glue supply control device supplies glue (glue stock) to the gluing equipment. During actual glue supply, glue stock can be stored in the glue barrel in advance, and the glue supply control device needs to extrude (extrude) the glue stock in the glue barrel, so that the glue stock is conveyed to the gluing equipment of each glue using station through a pipeline.

For example, chinese patent publication No. CN204953242U discloses a hydraulic glue extruder, which includes a first hydraulic cylinder, a material barrel clamp, and a glue extruding mechanism with a glue extruding channel, wherein the material barrel is disposed in the material barrel clamp, the glue extruding mechanism is located above the material barrel, a glue outlet communicated with the glue extruding channel is disposed on the glue extruding mechanism, and a first piston rod of the first hydraulic cylinder is connected to the glue extruding mechanism. The hydraulic rubber extruder in the scheme is also a rubber supply control device, and comprises a rubber barrel placing table (equivalent to the material barrel clamp) for placing a rubber barrel, a rubber extruding assembly for extruding rubber materials in the rubber barrel, and a rubber material conveying unit (equivalent to the rubber outlet) for conveying the rubber materials to each rubber coating device; the extrusion glue assembly comprises a pressure plate (equivalent to the above extrusion glue mechanism) for extruding glue and a pressure plate lifting unit (equivalent to the first piston rod of the above first hydraulic cylinder) for driving the pressure plate to lift. During the use, glue the bucket and be fixed in on gluey bucket placing table, drive the pressure disk by manual control pressure disk lifting unit and descend and extrude the sizing material in gluing the bucket for the sizing material is carried to each and is glued the rubber coating equipment department of station through sizing material conveying unit.

In the actual gluing process, the glue barrel needs to be replaced after the glue in the glue barrel is used up, and at the moment, the pressure plate lifting unit needs to be controlled to drive the pressure plate to lift to separate from the glue barrel, and then the glue barrel needs to be replaced; however, because the contact between the pressure plate and the side wall of the glue barrel is very tight (in order to ensure the glue squeezing effect) and the glue has certain viscosity, the glue barrel can rise along with the rising of the pressure plate, namely the pressure plate and the glue barrel are difficult to separate. In order to make the pressure disk faster, more effectual break away from gluey bucket, set up among the prior art and can be to gluing the interior "inflation unit that blows" (conveying gas) of bucket, when changing gluey bucket promptly, staff control pressure disk lift unit and inflation unit work for when pressure disk lift unit drives the pressure disk and rises, inflation unit is to gluing and is filled into compressed air in the bucket, applys decurrent pressure for gluing the bucket by compressed air, thereby can break away from gluey bucket with higher speed (supplementary) pressure disk.

However, the existing glue supply control device is manually controlled by a worker to work by the pressure plate lifting unit and the inflating unit, so that the rising speed of the pressure plate and the inflating quantity of the inflating unit are difficult to balance, and the existing glue supply control device has the following problems: 1) when the pressure plate rises too fast or the inflation quantity is insufficient, the glue barrel rises together with the pressure plate, so that the pressure plate and the glue barrel are difficult to separate, or the pressure plate and the glue barrel need to rise to a high position to separate, the barrel replacement efficiency of the glue supply control device is low, and the glue barrel is in a state with a large ground clearance when being separated from the pressure plate, namely the glue barrel falls, so that workers are easily injured, and the use safety of the glue supply control device is poor; 2) the condition that the glue bucket can have "suppress pressure" (the atmospheric pressure in the glue bucket is too high) when the pressure disk rising speed is too slow or the gas charge is too high, and then makes the pressure disk burst very big impact force in the twinkling of an eye with glue bucket and break away from, and this causes the staff injured very easily, leads to supplying to glue controlling means's safety in utilization not good too much equally.

Disclosure of Invention

Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a glue supply control device and a control method thereof which can take into account the barrel replacement efficiency and the barrel replacement safety when replacing a glue barrel, thereby improving the glue supply effect of the glue supply control device.

In order to solve the technical problems, the invention adopts the following technical scheme:

an automobile glue supply control device comprises a glue barrel placing table, a pressure plate and a pressure plate lifting unit, wherein the glue barrel placing table is used for placing a glue barrel, the pressure plate is arranged in parallel with a placing surface of the glue barrel placing table and is used for extruding glue materials in the glue barrel, and the pressure plate lifting unit is used for driving the pressure plate to lift; the device also comprises an inflation unit, a ground lift detection unit and a control unit;

the inflation unit is electrically connected with the control unit and used for outputting gas from the bottom position of the pressure plate during work;

the ground clearance detection unit is in signal connection with the control unit and is used for acquiring ground clearance data of the glue barrel relative to the glue barrel placing table;

the control unit is also electrically connected with the pressure plate lifting unit and is used for controlling the pressure plate lifting unit and the inflating unit to work so as to enable the pressure plate to ascend and the inflating unit to output gas; the control unit is also used for receiving the ground clearance data of the glue barrel acquired by the ground clearance detection unit, and adjusting the working states of the pressure plate lifting unit and the inflation unit according to the ground clearance of the glue barrel so as to control the ground clearance of the glue barrel, so that the ground clearance of the glue barrel is not more than the set safe ground clearance all the time.

In the actual glue supply process, when glue is discharged, the control unit controls the pressure plate lifting unit to drive the pressure plate to descend and move towards the glue barrel placed on the glue barrel placing table, the pressure plate extrudes glue in the glue barrel, and the glue conveying unit conveys the glue to glue coating equipment of each glue using station; when the rubber barrel is replaced, the control unit controls the pressure plate lifting unit to drive the pressure plate to lift, and controls the inflation unit to output gas into the rubber barrel from the bottom position of the pressure plate according to a set gas output quantity (towards the bottom of the rubber barrel); meanwhile, the control unit receives the ground clearance of the rubber barrel in real time, and can adjust the working states of the pressure plate lifting unit and the inflation unit according to the ground clearance of the rubber barrel so as to control the ground clearance of the rubber barrel.

Firstly, when the ground clearance of the rubber barrel in the scheme is larger (when the safe ground clearance is reached), the control unit can control the pressure plate lifting unit to stop working (or correspondingly slow down the lifting speed of the pressure plate) and control the inflating unit to keep the set gas output quantity to perform inflating work or increase the gas output quantity, so that the pressure plate and the rubber barrel can be separated faster and more effectively, meanwhile, the problem that workers are injured due to falling of the rubber barrel due to overhigh ground clearance can be avoided, and the barrel changing efficiency and the barrel changing safety during the replacement of the rubber barrel can be improved; secondly, when the ground clearance of the rubber barrel is smaller than the safe ground clearance, the control unit controls the pressure plate lifting unit to work (or correspondingly quickens the lifting speed of the pressure plate) and controls the inflating unit to be smaller than the set gas output quantity to inflate or stop working, so that the condition that the rubber barrel is 'suppressed' can be avoided, the impact force at the moment that the pressure plate is separated from the rubber barrel can be reduced, and the barrel replacing safety during replacing the rubber barrel can be improved; in addition, the ground clearance with gluing the bucket in this scheme is as control pressure disk lift unit and the basis of aerifing the unit, on the one hand, the ground clearance of gluing the bucket can react the operating condition (ground clearance) of gluing the bucket well to be favorable to better control pressure disk lift unit and the work of aerifing the unit, on the other hand, the ground clearance data of gluing the bucket have gather quick, convenient advantage, be favorable to timely, the operating condition of bucket is glued in accurate feedback, thereby can promote the confession of supplying to glue controlling means and glue the control effect.

Consequently, car in this scheme supplies to glue controlling means can compromise the bucket efficiency of trading when changing gluey bucket and trade bucket security to can promote and supply gluey control effect.

It should be noted that the ground clearance described herein refers to a variation between a detected ground clearance value when the glue barrel is detached from the ground and a detected ground clearance value when the glue barrel is completely dropped on the ground, that is, if the detected ground clearance value detected by the distance sensing assembly is Xmm when the glue barrel is completely dropped on the ground and the detected ground clearance value detected by the distance sensing assembly when the glue barrel is detached from the ground is (X + Y) mm, the detected ground clearance should be Ymm.

Preferably, the control unit adjusts the specific mode of the working states of the pressure plate lifting unit and the inflating unit according to the ground clearance of the rubber barrel:

when the rubber barrel is replaced, the control unit controls the pressure plate lifting unit to drive the pressure plate to lift, controls the inflation unit to output gas into the rubber barrel from the bottom position of the pressure plate according to a set gas output quantity, and simultaneously receives the ground clearance of the rubber barrel in real time; when the ground clearance of the rubber barrel reaches the safe ground clearance, the control unit controls the pressure plate lifting unit to stop working and controls the inflation unit to keep the set gas output quantity to perform inflation work or increase the gas output quantity; when the ground clearance of the rubber barrel reaches the minimum ground clearance, the control unit controls the pressure plate lifting unit to work and controls the inflating unit to reduce the gas output to inflate or stop working; therefore, the ground clearance of the glue barrel is not more than the set safe ground clearance all the time.

At the actual in-process that supplies to glue, stop and operating condition through control pressure disk lift unit and the unit of aerifing controls the terrain clearance of gluing the bucket: when the ground clearance of the rubber barrel reaches the safe ground clearance, the control unit controls the pressure plate lifting unit to stop working and controls the inflation unit to keep the set gas output quantity to perform inflation work or increase the gas output quantity; and when the ground clearance of the rubber barrel reaches the minimum ground clearance, the control unit controls the pressure plate lifting unit to work and controls the inflating unit to reduce the gas output to inflate or stop working. The regulative mode in this scheme can make the pressure disk with glue the bucket faster, more effectual breaking away from, and make the terrain clearance of gluing the bucket not more than the safe terrain clearance that sets up all the time, this can enough avoid appearing the condition of gluing bucket "suppressing pressure", can also practice thrift the working cost of inflating the unit (practicing thrift electric energy and gaseous output quantity), thereby the bucket efficiency of trading when having promoted the change and gluing the bucket and trade bucket security, the working cost when can practicing thrift the change and gluing the bucket, and can promote the confession of gluing controlling means and glue control effect.

Preferably, the height of the safe ground is 1-2 mm; the minimum ground clearance is 0-0.5 mm.

In research and experiments, the applicant finds that according to different conditions such as the material of the glue barrel, the type of glue used and the like, when the height of the glue barrel from the ground is within 1-2 mm, the normal separation from the pressure plate is hardly influenced, and meanwhile, the glue barrel can stably fall down without smashing workers; according to different conditions such as the material of the glue barrel, the type of glue used and the like, when the height of the glue barrel above the ground is more than 1-2 mm, the glue barrel has the problem of unstable falling, and workers are easily injured by crashing; and, the minimum ground clearance 0~0.5 mm's setting can be fine avoid detection device's measuring error, can avoid the problem that the glue bucket appears "suppressing pressure". Based on this, set up safety terrain clearance into 1~2mm in this scheme, minimum terrain clearance establishes to 0~0.5mm for can guarantee to change the bucket security of trading when gluing the bucket under the prerequisite that does not influence the pressure disk and glue the bucket and normally break away from, thereby can promote to supply to glue controlling means's confession and glue control effect.

Preferably, the control unit is further configured to execute the received glue discharging control instruction to control the pressure plate lifting unit to drive the pressure plate to descend to extrude the glue material in the glue barrel, and the control unit stops executing other control instructions when executing the glue discharging control instruction.

In the actual glue supply process, the downward pressure of the glue is required to be continuously supplied when the glue is discharged, namely, the pressure plate lifting unit needs to continuously drive the pressure plate (and the glue conveying unit on the pressure plate) to descend, and at the moment, misoperation such as inputting 'pressure plate ascending', 'glue barrel replacement' or other conflicting control instructions easily occurs to the working personnel, so that the glue supply control effect and quality of the glue supply control device can be influenced, and safety accidents are easy to occur. To this problem, receive out gluey control command when the control unit in this scheme, and control pressure disk lifting unit drives the pressure disk and descends when extrudeing the sizing material in gluing the bucket, other control command no longer of control unit execution (do not receive promptly "pressure disk rises", "change gluey bucket" or other conflicting control command) for the play of pressure disk elevating system and pressure disk is glued the action and can be continuously gone on, and this emergence that can enough avoid the incident can also guarantee to supply gluey controlling means's confession to glue control effect and quality.

Moreover, in order to facilitate the control and use of workers, the glue supply control device can comprise two working states: namely an "enabled state" and a "disabled state"; under the 'enabling state', the control unit executes the working logic (namely, the continuity of the glue discharging action of the pressure plate lifting mechanism and the pressure plate is ensured), and under the 'disabling state', the control unit can stop executing a glue discharging control instruction and execute other newly input control instructions when the pressure plate descends to extrude glue; in addition, the control unit can also receive an emergency stop instruction (namely, an emergency button is arranged) so as to stop the glue discharging action in an emergency.

Preferably, the automobile glue supply control device further comprises a stroke detection unit which is in signal connection with the control unit and is used for acquiring lifting stroke data of the pressure plate lifting unit; the control unit is used for receiving the lifting stroke data of the pressure plate lifting unit acquired by the stroke detection unit and calculating the material level height of the rubber material in the rubber barrel according to the lifting stroke of the pressure plate lifting unit.

In the actual glue supply process, the existing glue supply control device can only give an alarm when the material level height of the glue material is at the set low level/vacancy height, but cannot monitor the material level height of the glue material in real time (namely cannot monitor the use/residual condition of the glue material in real time), and because the existing liquid level sensor and other equipment are not suitable for material level detection of the glue material, the material level height of the glue material is difficult to be monitored and managed in real time, and the glue supply control effect of the glue supply control device is poor. Aiming at the problem, the lifting stroke data of the pressure plate lifting unit is obtained through the stroke detection unit in the scheme, the descending height of the pressure plate and the lifting stroke of the pressure plate lifting unit have a corresponding relation during glue supply, namely the descending height of the pressure plate can be calculated through the lifting stroke of the pressure plate lifting unit; the descending height of the pressure plate corresponds to the extruded and used material level height of the rubber material, namely the corresponding material level height of the rubber material can be calculated through the descending height of the pressure plate, so that the real-time monitoring and management of the material level height of the rubber material in the rubber barrel can be realized, and the rubber supply effect of the rubber supply control device can be improved; and, the material level height of sizing material is calculated through the lift stroke that acquires pressure disk lift unit in this scheme, and the material level height detection problem that will originally be complicated is simplified, and the lift stroke can accurately reflect the material level height of sizing material, is favorable to further promoting the confession of supplying gluey controlling means and glues the control effect.

Preferably, the pressure plate lifting unit comprises a lifter with a lifting output end arranged vertically upwards, a lifting cross beam fixedly arranged at the lifting output end of the lifter, and a pressure plate pull rod with an upper end fixedly connected with the lifting cross beam and a lower end fixedly connected with the pressure plate; the glue barrel placing table is arranged at the position, right opposite to the pressure plate, of the bottom of the elevator.

In-process is glued in actual confession, the lift drives the pressure disk through lifting beam and pressure disk pull rod and goes up and down, and glues the bucket and place the platform and arrange in the bottom of lift just to the position of pressure disk and (place the face parallel with the pressure disk), and this kind of arrangement mode not only makes the pressure disk can be better the extrusion glue sizing material in the bucket, still does benefit to the pressure disk and glues the better breaking away from of bucket to can assist the promotion to supply gluey control device's confession to glue control effect.

Preferably, the stroke detection unit comprises a pull rope sensor with a data output end in signal connection with the control unit and a moving wire end in transmission connection with the lifting beam, and the moving wire end of the pull rope sensor can move along with the lifting beam.

In the actual glue supply process, when the lifting machine drives the pressure plate to lift through the lifting cross beam (and the pressure plate pull rod), the moving line end of the pull rope sensor can move along with the lifting of the lifting cross beam, so that the pull rope sensor can measure the lifting stroke data of the lifting machine, the control unit can calculate the corresponding material level height of the glue material according to the lifting stroke, the glue material in the glue barrel can be better monitored and managed, and the glue supply control effect of the glue supply control device can be improved; and, the stay cord sensor has the effect of measuring stably, accurately, is favorable to the supplementary gluey control effect that supplies of promoting to glue controlling means.

Preferably, the inflation unit comprises an air source and an air pipe, wherein an air inlet end of the air pipe is communicated with the air source, and an air outlet end of the air pipe is communicated with an inflation hole formed in the bottom of the pressure plate; and the air pipe is also provided with an on-off electric control valve which is used for controlling the on-off of the air pipe and is electrically connected with the control unit.

In the actual glue supply process, the control unit controls the on-off electric control valve to realize the on-off control of the air pipe, so that the start and stop of the inflation unit can be well controlled, the barrel replacement efficiency and the barrel replacement safety during replacement of the glue barrel can be improved, the cost during replacement of the glue barrel can be saved, and the glue supply control effect of the glue supply control device can be improved; and, the mode of controlling the trachea break-make through the solenoid valve has the effect that the response is quick, control is accurate, is favorable to promoting the confession of supplying gluey controlling means to glue the control effect equally.

The invention further discloses an automobile glue supply control method, which is implemented based on the automobile glue supply control device, and when the glue barrel is replaced, the control process comprises the following steps:

step A: firstly, controlling a pressure plate lifting unit to drive a pressure plate to lift, and controlling an inflating unit to output gas into a rubber barrel from the bottom position of the pressure plate according to a set gas output quantity;

and B: acquiring the ground clearance of the glue barrel relative to the glue barrel placing table in real time;

and C: when the ground clearance of the rubber barrel reaches the safe ground clearance, controlling the pressure plate lifting unit to stop working and controlling the inflating unit to keep the set gas output quantity to perform inflating work or increase the gas output quantity; when the ground clearance of the rubber barrel reaches the lowest ground clearance, the pressure plate lifting unit is controlled to work, and the inflating unit is controlled to be smaller than the set gas output quantity to inflate or stop working.

In the actual glue supply process, when the glue barrel is replaced, the control pressure plate lifting unit drives the pressure plate to ascend, controls the inflation unit to output gas (towards the bottom of the glue barrel) according to the set gas output quantity from the bottom of the pressure plate to the inside of the glue barrel, receives the ground clearance of the glue barrel in real time, can adjust the working state of the pressure plate lifting unit and the inflation unit according to the ground clearance of the glue barrel, and can control the ground clearance of the glue barrel.
