Detailed Description

The liquid material discharge head of the present invention is a hand-held liquid material discharge head including a nozzle and a liquid storage portion, and includes a pickup member arranged in line with the nozzle. Here, the pick-up member is a member for holding the mounting member, and may be a rod-shaped member having an adsorption resin provided at the tip end thereof. More preferably, a negative pressure operation portion that adjusts the negative pressure is provided in the liquid material ejection head.

The liquid storage unit may be constituted by a liquid chamber that temporarily stores the liquid supplied from the tank, but a syringe capable of storing the liquid material in an amount necessary for one mounting operation is preferably used. The discharge of the liquid material from the nozzle can be achieved by pressing the flexible liquid storage portion with a hand, but it is preferable to adopt a configuration in which pressurized air is supplied to the liquid storage portion. The liquid material ejection head may be provided with an ejection operation unit for controlling ON/OFF (ON/OFF) of the pressurized air applied to the liquid reservoir unit.

In order to facilitate the picking operation and the coating operation, it is preferable that the nozzle and the picking member are configured such that a distance between the tips is wider than a distance between the picking member and the base of the nozzle. In other words, it is preferable that the central axis of the picking member and the central axis of the nozzle are configured to be wider toward the tips of the picking member and the nozzle.

Hereinafter, a liquid material discharge device according to an embodiment will be described with reference to the drawings.

< first embodiment example >

As shown in fig. 1, the liquid material discharge device 1 according to the first embodiment includes a discharge head 10, a controller 20, and an air compressor 30. The liquid material discharge device 1 is of a hand-held type, and is used for applying an adhesive for adhering a decorative member (mounting member S) such as a jewel to an accessory such as a pendant.

[ Structure ]

As shown in fig. 2, the discharge head 10 includes a nozzle 11, a syringe 12, holders 13 and 14, a pickup member 15, a suction tube 16, and a cover member 18.

The nozzle 11 is made of resin or metal, and has a discharge port 11a at its tip. The nozzle 11 is selected and used from a plurality of nozzles having different diameters of the discharge port 11a depending on the application. The diameter of the discharge port 11a is, for example, 0.2 to 2 mm.

The syringe 12 is a liquid storage section made of resin or metal, and has a connecting section at a lower end (tip) thereof for detachably attaching the nozzle 11. The syringe 12 is selected from a plurality of syringes having different capacities and used in accordance with the purpose. The syringe 12 is filled with, for example, an epoxy adhesive or an ultraviolet curable resin. A flange portion is provided at the upper end (rear end) of the syringe 12, and a lid member 18 is attached to the flange portion.

The holder 13 is provided with a nozzle insertion hole through which the nozzle 11 is inserted and a suction tube insertion hole through which the pickup member 15 is inserted, and supports a lower portion of the syringe 12. The nozzle 11 is inserted through the nozzle insertion hole of the holder 13, and the pickup member 15 is inserted through the pickup member insertion hole. The retainer 13 includes a fixing member 13a for detachably fixing the pickup member 15, and the fixing member 13a can be easily replaced by being released.

The holder 14 is provided with a syringe insertion hole through which the syringe 12 is inserted and a suction tube insertion hole through which the suction tube 16 is inserted, and supports the vicinity of the flange portion of the syringe 12. The holder 14 is provided with a through hole that engages with the hook 41 of the base 40.

In the present embodiment, the holder 13 and the holder 14 are configured by different members, but the holder 13 and the holder 14 may be configured by one member.

The pickup member 15 is made of resin or metal, and has a suction port 15a at a front end portion thereof. The opening at the end of the picking-up member 15 opposite to the suction port 15a is detachably connected to the suction pipe 16. In the first embodiment, the pickup member 15 is constituted by a general-purpose nozzle. The pickup member 15 selects a nozzle having a bore which exerts a desired suction force from among a plurality of nozzles having different discharge port diameters.

The nozzle 11 and the picking member 15 are arranged such that the distance between the central axis of the nozzle 11 and the central axis of the picking member 15 becomes wider toward the front end. In other words, the picking member 15 is arranged such that the distance between the picking member 15 and the front end portion of the nozzle 11 is wider than the distance between the picking member 15 and the base portion of the nozzle 11. With this configuration, the nozzle 11 does not interfere with the picking-up and placing operations of the mounting member S, and therefore, the workability can be improved.

The nozzle 11 and the pickup member 15 according to the first embodiment are made of resin and are disposable.

The suction tube 16 is a flexible resin tube, and a negative pressure operation portion 17 is provided adjacent to the syringe 12. The negative pressure operation portion 17 is a resin cylinder and has an opening 17 a. When negative pressure is applied to the suction pipe 16 to block the opening 17a with a finger, the inside of the suction pipe 16 becomes negative pressure, and suction force can be generated at the suction port 15 a. A plurality of openings 17a may be provided, and the suction force generated at the suction port 15a may be adjusted by adjusting the number of the blocked openings. It is preferable that the suction pipe 16 be provided with a backflow prevention mechanism (valve or filter) for preventing backflow of the liquid material or foreign matter.

Unlike the present embodiment, a mechanism that opens and closes the opening by a key operation to open and close the negative pressure may be used as the negative pressure operation unit, and the negative pressure operation unit may be disposed in the suction tube 16 or the holder 13. Alternatively, the holder 14 may be omitted, the suction tube insertion hole may be provided in the cover member 18, and the suction tube 16 may be supported by the cover member 18.

The suction duct 16 communicates the negative pressure air supply port 21 of the controller 20 with the pickup member 15. The controller 20 includes a negative pressure generating device (e.g., an ejector) in the main body, and generates a desired negative pressure in the negative pressure air supply port 21 via a negative pressure adjusting device (e.g., a regulator for negative pressure). The negative pressure generated at the negative pressure air supply port 21 can be adjusted by the negative pressure adjusting knob 25.

The controller 20 includes a pressurized air supply port 22, and the pressurized air supply port 22 communicates with the cover member 18 via a pressurization pipe 23. The controller 20 has a time-series discharge mode for controlling the timing of the pressure applied to the pressure pipe 23. The time-series discharge mode is a mode for applying an adhesive or the like in a uniform spot-like fixed amount, and performs timing control in which the supply of pressurized air is applied to the pressure pipe 23 at predetermined intervals.

The controller 20 includes a pressurized air receiving port (not shown) that communicates with the air compressor 30. Pressurized air is supplied from the air compressor 30 to the pressurized air receiving port, and a desired pressurizing force is generated at the pressurized air supply port 22 via a pressure-adjusting regulator in the controller 20. The pressurizing force generated at the pressurized air supply port 22 can be adjusted by pressurizing the adjustment knob 26.

The controller 20 includes a discharge operation unit for on/off controlling the discharge operation of the liquid material. In the first embodiment, the discharge operation portion is constituted by the foot switch 24 electrically connected to the controller 20 via a signal cable. The operator can control the discharge operation of the liquid material on/off by operating the foot switch 24 with his foot. Unlike the present embodiment, the ejection head 10 may be configured to supply pressurized air of a strength corresponding to the amount of depression of the foot switch 24 and to adjust the ejection amount.

Further, a button or a knob, which functions as a discharge operation portion, may be provided separately from the foot switch 24 in the main body of the controller 20 or the discharge head 10. For example, the mechanism described in patent document 2 may be adopted in the ejection operation unit.

[ method of use ]

A method of using the liquid material discharge apparatus 1 according to the first embodiment will be described with reference to fig. 3, as an example of an operation of sticking a jewel (mounting member) S to a workpiece W in a desired pattern.

(step 1) a gemstone S is arranged in a desired pattern on the surface of a workpiece W.

Step 2 As shown in FIG. 3A, the worker closes the opening 17a of the negative pressure operation part 17 with his/her finger, and causes the suction port 15a of the picking-up member 15 to generate suction force to pick up the gemstone S to be stuck.

Step 3 As shown in FIG. 3B, the discharge port 11a of the nozzle 11 is moved to a position where the picked-up gemstone S is present while the gemstone S is held by the pick-up member 15, and the foot switch 24 is operated to apply the adhesive L. Here, the movement of the discharge port 11a can be simply realized by tilting the wrist.

(step 4) as shown in fig. 3(c), the worker places the picked-up gem S on the adhesive L applied. Here, the movement of the gemstone S can be simply achieved by tilting the wrist. The gem S can be pressed down by the tip (suction port 15a) of the picking-up member 15 to be reliably attached.

Step 5 As shown in FIG. 3D, the worker releases the opening 17a of the negative pressure operation part 17, thereby eliminating the suction force of the picking-up member 15 and releasing the holding of the jewel S.

According to the liquid material discharge device 1 of the first embodiment described above, the picking-up operation of the mounting member S, the application operation of the adhesive L, and the placement operation of the mounting member S can be performed without replacing the discharge head 10 with another device. That is, it is not necessary to use different devices for the picking-up and placing operations of the mounting member S and the application operation of the adhesive L as in the related art.

Further, since the distance between the picking member 15 and the tip portion of the nozzle 11 is set to be larger than the distance between the picking member 15 and the base portion of the nozzle 11, the picking operation and the mounting operation of the mounting member S can be performed without being obstructed by the nozzle 11.

Further, since the mounting member S can be mounted after the pattern of the mounting member S is actually arranged on the workpiece W and confirmed, the workability of the operator can be improved. Conventionally, in order to perform the coating work after the picking work by the picking work device, the picking work device and the coating work device are replaced 2 times, and therefore, it is difficult to perform the work procedure of the present invention.

< second and third embodiments >

Fig. 4(a) is a configuration diagram of the ejection head 10 according to the second embodiment, and (b) is a configuration diagram of the ejection head 10 according to the third embodiment. The second embodiment is different from the first embodiment in that the pickup member 19 having the curved portion 19b is coupled to the suction pipe 16. The third embodiment differs from the second embodiment in that the suction pipe insertion hole is provided in the holder 13 so that the trunk portion 19a of the pickup member 19 and the nozzle 11 are arranged in parallel. Hereinafter, description will be given mainly on differences, and the same reference numerals are given to the same components as those of the first embodiment, and description thereof will be omitted.

The pickup member 19 according to the second embodiment includes a body portion 19a and a bent tube 19b extending from the body portion 19 a. In the second embodiment, as in the first embodiment, the distance between the leading end portion and the base portion of the nozzle 11 is larger than the distance between the pickup member 19 and the base portion.

The picking member 19 of the third embodiment is the same as that of the second embodiment, and only the holder 13 is different. In the third embodiment, the body 19a of the pickup member 19 is disposed in parallel with the nozzle 11, but the tip of the bent tube 19b is disposed in a direction away from the nozzle 11, and therefore, the distance between the tip is larger than the distance between the pickup member 19 and the base of the nozzle 11.

Further, the pickup member 19 may be disposed so that the suction port 19c opens to the side (the near side or the far side in fig. 4) as long as the distance of the leading end portion is larger than the distance of the pickup member 19 from the base portion of the nozzle 11. That is, as shown in fig. 5, the picking member 19 may be disposed such that the suction port 19c of the picking member 19 is disposed at a position (for example, positions a to d in fig. 5) shifted from the straight line R passing through the centers of the nozzle 11 and the picking member 19.

In the second and third embodiments described above, as in the first embodiment, the picking-up operation of the mounting member S, the application operation of the adhesive L, and the placement operation of the mounting member S can be performed without replacing the discharge head 10 with another device.

Further, as in the first embodiment, the nozzle 11 does not interfere with the picking up and placing operations of the mounting member S, and the workability can be improved.

Although the preferred embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the description of the above embodiments. Various modifications and improvements can be added to the above embodiment, and embodiments to which such modifications and improvements are added are also included in the technical scope of the present invention. For example, in the first to third embodiments, the configuration example 1 shown in table 1 below is used, but the technical idea of the present invention can be realized by using the configuration examples 2 to 4 shown in table 1 below.
