Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In order to solve the above technical problem, an embodiment of the present invention provides a peripheral device control method for an injection molding machine, which is applied to a controller connected between the injection molding machine and a peripheral device of the injection molding machine. Fig. 1 is a flowchart illustrating a peripheral device control method of an injection molding machine according to an embodiment of the present invention. Referring to fig. 1, the method includes at least steps S102 to S108.

And step S102, after detecting a full-automatic operation signal of the injection molding machine, if a mold closing signal of the injection molding machine is received or a mold opening completion signal is not received, forbidding sending a signal for allowing the manipulator in the peripheral equipment to enter the mold, wherein the signal for allowing the manipulator to enter the mold of the injection molding machine to take out the injection molding product.

In this step, the full-automatic operation signal of the injection molding machine is used to represent that the injection molding machine is in the full-automatic operation mode at this time.

And step S104, acquiring temperature parameters of a mold detected by temperature detection equipment in peripheral equipment, and if the acquired temperature parameters exceed the corresponding preset parameter range, forbidding sending of a mold closing permission signal to the injection molding machine, wherein the mold closing permission signal is used for permitting the injection molding machine to close the mold.

And step S106, when the mold closing completion signal of the injection molding machine is received, forbidding sending a recycling signal to the injection molding machine, wherein the recycling signal is used for allowing the injection molding machine to close the mold again.

And step S108, when the mold opening completion signal of the injection molding machine is received, sending a signal for allowing the mold to enter to the manipulator.

In this step, when a signal for allowing entry into the mold is sent to the robot, the signal for allowing mold closing to the injection molding machine is prohibited from being sent, and the mold is prevented from being started when the robot is in the mold.

In the embodiment of the present invention, the prohibition of sending the signal for allowing entry of the mold to the manipulator means that if the controller previously sends the signal for allowing entry of the mold to the manipulator, the signal for allowing entry of the mold to the manipulator needs to be cut off when the signal for allowing entry of the mold to the manipulator is received while the signal for allowing entry of the mold to the mold is being closed or the signal for completing mold opening is not received, and if the signal for allowing entry of the mold is not previously sent to the manipulator, the signal for allowing entry of the mold is prohibited from being sent to the manipulator while the signal for allowing entry of. Of course, the same applies to the controller inhibiting the mold clamping enable signal from being sent to the injection molding machine, inhibiting the recirculation signal from being sent to the injection molding machine, and the signal inhibiting the sending referred to hereinafter, and will not be described in detail here.

The embodiment of the invention arranges the controller between the injection molding machine and the peripheral equipment of the injection molding machine, so that the injection molding machine does not directly carry out information interaction with the peripheral equipment, and the problem that the connection of various peripheral equipment cannot be met due to the limited open signal interface on the injection molding machine is avoided. The controller can efficiently realize the injection molding process of the injection molding machine by correspondingly controlling the injection molding machine and peripheral equipment thereof, and the controller has serial port communication capability usually, so the temperature parameter of the mold detected by the temperature detection equipment in the peripheral equipment can be effectively obtained based on the serial port communication capability of the controller so as to effectively monitor the temperature of the mold.

In an embodiment of the present invention, after the controller sends a signal allowing entry into the mold to the manipulator after receiving the mold opening completion signal of the injection molding machine in step S108, if the injection product of the manipulator is taken out, injection molding of one product is completed, so the controller may also send a recycling signal to the injection molding machine after receiving the injection product of the manipulator taken out, where the recycling signal is used to control the injection molding machine to start mold closing again, that is, to control the injection molding machine to perform injection molding of the next product.

In this embodiment, the controller may further determine whether the peripheral device of the injection molding machine has a failure before sending the recirculation signal to the injection molding machine, and if the peripheral device has a failure, the injection molding machine is not started temporarily, specifically, when the controller receives a signal that an injection product of the robot has been taken out, the controller determines whether an alarm signal of any peripheral device is received, the alarm signal is used to perform a failure alarm on the peripheral device, and if the controller does not receive the alarm signal of any peripheral device, it may be determined that each peripheral device is in a normal state, and at this time, the controller sends the recirculation signal to the injection molding machine.

In addition, the Controller in the embodiment of the present invention may adopt a PLC (Programmable Logic Controller), and of course, the Controller may also adopt other types of controllers, which is not specifically limited in this embodiment of the present invention.

In an embodiment of the present invention, the peripheral device may further include a mold cavity monitor, and the mold cavity monitor may obtain whether the product exists in the cavity of the mold by photographing an image of the cavity of the mold to analyze whether the injection molded product exists in the image. When the controller receives a signal that the injection product of the robot has been taken out, a request for acquiring the monitoring information may be sent to the mold cavity monitor to feed back the monitoring information to the controller by the mold cavity monitor. When the controller acquires that the monitoring information sent by the mold cavity monitor is that the injection molding product information is not monitored, the controller can determine that the injection molding product is taken out by the manipulator, and sends a recycling signal to the injection molding machine. If the monitoring information acquired by the controller is the information of the injection molding product, the injection molding product can be determined not to be successfully taken out by the manipulator, and the controller sends out an alarm signal at the moment.

In this embodiment, the mold cavity monitor may be configured to monitor whether the injection product is located in a mold cavity of the mold, and may also monitor whether the injection product is unqualified, for example, after the controller receives a mold opening completion signal of the injection molding machine, a request for obtaining information of the injection product may be sent to the mold cavity monitor, the mold cavity monitor feeds back the monitored information of the injection product to the controller, where the information of the injection product fed back to the controller may be that the injection product is a qualified product or that the injection product is an unqualified product, and the unqualified product refers to that the injection product has the problems of glue shortage, incomplete injection product, and the like. And the controller sends out an alarm signal when receiving the information that the injection product is an unqualified product or controls the manipulator to take out the injection product and separately place the unqualified product and the qualified product.

According to the embodiment, the controller can perform good interlocking control on the received signals of the injection molding machine during mold closing and the signals of allowing the injection molding machine to enter a mold, the mold closing completion signals of the injection molding machine, the recycling signals and the like, so that when the mold closing is performed in the full-automatic operation mode of the injection molding machine, the manipulator is forbidden to enter the mold, after the mold closing is completed, the mold closing is forbidden to be started again, the injection molding machine is prevented from closing again, the mold closing is started again for the injection molding machine after the injection molding product is taken out by the standby manipulator, and the safety of the mold and the manipulator of the injection molding. Of course, the interlocking of other signals may be involved in the actual operation of the injection molding machine, and the examples are merely illustrative and do not limit the present application in any way.

The signal transmission process of the controller, the injection molding machine and various peripheral devices is introduced, the injection molding machine and the various peripheral devices are correspondingly controlled by acquiring information fed back by the injection molding machine and the various peripheral devices, actually, because the injection molding process of the injection molding machine is relatively complex, other signals are transmitted between the controller and the injection molding machine and the various peripheral devices, for example, the injection molding machine can also inform the controller of the opening and closing signals of the safety door in the injection molding process, and the controller controls the mold cavity monitor to monitor injection molding products when the safety door is opened. The injection molding machine can set parameter ranges such as injection molding time, injection molding peak pressure, filling time and the like, and the injection molding machine can detect the actual injection molding time, injection molding peak pressure, filling time and the like of an injection molding product in the injection molding process to determine whether the actually detected parameter values are in the set parameter value ranges, and if the injection molding machine detects that the parameter values of the injection molding product are not in the parameter value ranges of the corresponding parameters, the injection molding machine can also send a signal that the injection molding product is a defective product to the controller, so that the controller controls the manipulator to take out the injection molding product when receiving the signal that the injection molding product is a defective product, and the unqualified product and the qualified product are separately placed.

In an embodiment of the present invention, since the controller includes a plurality of IO interfaces, an input interface and an output interface of the IO interfaces may be defined in groups, where the input interface and the output interface connected to the injection molding machine are a group, and the input interface and the output interface connected to each peripheral device are a group, respectively, so that series and parallel connection of connection lines is simplified, and control of the controller is facilitated. In this embodiment, an input interface of the definition controller connected to the injection molding machine is used for receiving a full-automatic operation signal, a mold closing completion signal, a mold opening completion signal, and a mold closing signal of the injection molding machine, and an output interface is used for outputting a mold closing permission signal and a recirculation signal to the injection molding machine. An input interface of the definition controller and the manipulator is used for receiving a signal that the injection molding product of the manipulator is taken out, and an output interface is used for sending a signal for allowing the mold to enter to the manipulator. When the manipulator enters the mold of the injection molding machine, a signal of entering the injection molding machine can be sent to the controller, namely, an input interface connected with the manipulator by the controller can also receive a signal of allowing the manipulator to enter the mold, so that the controller knows that the manipulator is positioned in the mold of the injection molding machine at the moment. The input interface of the definition controller connected with the mold cavity monitor is used for receiving signals that the injection molding product is not monitored and signals that the injection molding product is monitored, and the output interface is used for outputting a request for acquiring monitoring information to the mold cavity monitor.

In this embodiment, in order to facilitate connection between the devices, a corresponding aviation male plug or aviation female plug may be further provided on the IO interface of the controller, and then a corresponding aviation male plug or aviation female plug may be further provided on the injection molding machine, the manipulator, and the mold cavity monitor. If the controller is provided with the aviation male plug, the injection molding machine and the peripheral equipment are provided with the aviation female plug, and if the controller is provided with the aviation female plug, the injection molding machine and the peripheral equipment are provided with the aviation male plug. The aviation male-female plug of the embodiment can adopt a Euromap67 male-female plug, and the embodiment of the invention is not particularly limited in this respect.

In an embodiment of the present invention, the temperature detection device may include a mold temperature controller and a hot runner temperature controller, and then the controller may compare the obtained mold temperature detected by the mold temperature controller with a preset mold temperature range, and when the obtained mold temperature exceeds the preset mold temperature range, the controller sends a mold clamping pause signal to the injection molding machine. The controller can also compare the hot runner temperature of the mold detected by the obtained hot runner temperature controller with a preset hot runner temperature range, and when the obtained hot runner temperature of the mold exceeds the preset hot runner temperature range, the controller prohibits sending a mold closing permission signal to the injection molding machine. The temperature detection equipment of the embodiment of the invention is connected with the communication interface of the controller, so that the controller obtains the temperature parameter of the mold through the communication interface.

The controller receives the definition of the communication interface of the controller, wherein the communication interface connected with the mold temperature controller is defined and used for acquiring the mold temperature information detected by the mold temperature controller. And defining a communication interface connected with the hot runner temperature controller for acquiring the hot runner temperature of the mold detected by the hot runner temperature controller. In this embodiment, if the controller adopts a programmable logic controller, the communication interface of the programmable logic controller may be an ethernet interface, which is not specifically limited in this embodiment of the present invention.

Based on the same inventive concept, an embodiment of the present invention further provides a peripheral device control system of an injection molding machine, and referring to fig. 2, a schematic structural diagram of a peripheral device control system of an injection molding machine according to an embodiment of the present invention is shown. Referring to fig. 2, the peripheral control system of the injection molding machine includes a controller 10 and an injection molding machine 20 connected thereto, and peripheral devices of the injection molding machine including a robot 30 and a temperature detecting device 40.

When the controller 10 detects the full-automatic operation signal of the injection molding machine 20 and receives the in-mold closing signal or the mold opening completion signal of the injection molding machine 20, it prohibits the transmission of the mold entry permission signal to the robot 30.

The robot 30 does not enter the mold of the injection molding machine 20 during the time when it does not receive the signal to allow entry of the mold.

The controller 10 acquires a temperature parameter of a mold detected by a temperature detection device 40 in the peripheral device, and if the acquired temperature parameter exceeds a corresponding preset parameter range, prohibits sending a mold closing permission signal to the injection molding machine 20, wherein the mold closing permission signal is used for permitting the injection molding machine 20 to close the mold.

The injection molding machine 20 suspends the mold clamping operation while the mold clamping permission signal is not received.

The controller 10 prohibits the sending of the recirculation signal to the injection molding machine 20 when receiving the mold clamping completion signal of the injection molding machine 20.

The injection molding machine 20 does not start the mold reclosing operation any longer in the process of not receiving the recirculation signal.

The controller 10 sends a mold admission signal to the robot 30 when receiving a mold opening completion signal of the injection molding machine 20.

When the robot 30 receives the signal for allowing the mold to be entered, the mold entered into the injection molding machine 20 takes out the injection molded product.

In an embodiment of the present invention, the controller 10 is plugged into the injection molding machine 20, and the controller 10 is plugged into any peripheral devices (e.g., the robot 30 and the temperature detecting device 40) by using male and female aviation plugs (not shown). Here, the aviation male and female plugs are connected to the IO interface of the controller 10.

Referring to fig. 3, in one embodiment of the present invention, the peripheral device further includes a mold cavity monitor 50 that interfaces with the communications of the controller 10.

Upon receiving the injection product take-out signal from the robot 30, the controller 10 transmits a request for acquiring monitoring information to the mold cavity monitor 50. Upon receiving the request for obtaining the monitoring information, the mold cavity monitor 50 transmits the monitoring information to the controller 10. If the acquired monitoring information indicates that the injection molding product information is not monitored, the controller 10 transmits a mold clamping permission signal and a recirculation signal to the injection molding machine 20. When the injection molding machine 20 receives the mold clamping permission signal and the recirculation signal, mold clamping is started. If the monitoring information acquired by the controller 10 is that the injection molding product is monitored, the controller 10 sends out an alarm signal.

Referring to fig. 2 and 3, in an alternative embodiment of the present invention, the temperature detecting device 40 may include a mold temperature controller 41 and a hot runner temperature controller 42, and then the controller 10 may compare the mold temperature detected by the mold temperature controller 41 with a preset mold temperature range, and when the obtained mold temperature is beyond the preset mold temperature range, the controller 10 prohibits sending a mold clamping permission signal to the injection molding machine 20. The controller 10 may further compare the acquired hot runner temperature of the mold detected by the hot runner temperature controller 42 with a preset hot runner temperature range, and when the acquired hot runner temperature of the mold exceeds the preset hot runner temperature range, the controller 10 prohibits sending of a mold clamping permission signal to the injection molding machine 20.

According to any one or a combination of the above preferred embodiments, the following advantages can be achieved by the embodiments of the present invention:

the embodiment of the invention arranges the controller between the injection molding machine and the peripheral equipment of the injection molding machine, so that the injection molding machine does not directly carry out information interaction with the peripheral equipment, and the problem that the connection of various peripheral equipment cannot be met due to the limited open signal interface on the injection molding machine is avoided. The controller can efficiently realize the injection molding process of the injection molding machine by correspondingly controlling the injection molding machine and peripheral equipment thereof, and the controller has serial port communication capability usually, so the temperature parameter of the mold detected by the temperature detection equipment in the peripheral equipment can be effectively obtained based on the serial port communication capability of the controller so as to effectively monitor the temperature of the mold.
