Description

Technical Field

[0001] The present invention relates to the technical field of battery module assembly, and in particular to a method, system, equipment and medium for automatic cleaning and gluing of battery modules. Background Art

[0002] With the continuous development of the new energy industry, the new energy vehicle manufacturing industry has also undergone repeated updates and iterations. The production process requirements for new energy vehicle battery modules are becoming increasingly stringent, and the automation requirements and cycle time of battery module production are also increasing. Before the battery modules are assembled into battery packs, they need to be cleaned and glued to better secure the battery modules.

[0003] Traditionally, the battery module cleaning system and gluing system are separate, requiring two control systems, which is costly. In addition, the cleaning process requires manual participation, which poses risks such as missed cleaning or incomplete cleaning. The gluing system cannot monitor and trace the gluing process data, and the quality of the gluing can only be manually identified, which lacks reliability.

[0004] Therefore, how to provide a method, system, equipment and medium for automatic cleaning and gluing of battery modules to improve the quality and traceability of battery module cleaning and gluing and reduce costs has become a technical problem that needs to be solved urgently. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a method, system, equipment and medium for automatic cleaning and gluing of battery modules, so as to improve the quality and traceability of battery module cleaning and gluing and reduce costs.

[0006] In a first aspect, the present invention provides a method for automatically cleaning and gluing a battery module, comprising the following steps:

[0008] Step S20: The PLC reads the AGV vehicle number and the module number of the battery module, and verifies the battery module based on the vehicle number and the module number.

[0009] Step S30: After the PLC locates the battery module using the 2D positioning camera on the robot, it controls the robot's quick-change plate to switch the plasma cleaner to the working position, and the robot moves the plasma cleaner to automatically clean the battery module.

[0010] Step S40: The PLC controls the robot's quick-change plate to switch the glue coating machine to the working position, and the robot moves the glue coating machine to automatically apply glue to the battery module;

[0011] Step S50: The PLC detects the glue coating quality of the battery module using a 3D glue detection camera installed on the robot and generates a detection result;

[0012] Step S60: The PLC records the battery module cleaning and gluing process through a 2D positioning camera to obtain a cleaning and gluing video, and sends the detection results and the cleaning and gluing video to the MES terminal through the host computer for archiving.

[0013] Furthermore, the step S20 is specifically as follows:

[0014] The PLC reads the AGV trolley number and the module number of the battery module, matches the module number from the database based on the trolley number, and determines whether the module number matched by the database is consistent with the read module number. If so, the battery module verification passes and enters step S30; if not, the battery module verification fails and the process ends.

[0015] Furthermore, the step S40 is specifically as follows:

[0016] The PLC controls the robot's quick-change plate to switch the glue applicator to the working position. The robot uses a 2D positioning camera to take pictures of the battery module, obtain the module pictures, and transmit them to the PLC.

[0017] The PLC calculates the compensation value of the module position based on the module photo, corrects the preset gluing trajectory based on the compensation value, and sets the pause time, gluing pressure, gluing amount and moving speed of each gluing point in the gluing trajectory;

[0018] The PLC controls the glue coating machine through a robot to automatically apply glue to the battery module based on the glue coating trajectory.

[0019] Furthermore, the step S50 is specifically as follows:

[0020] The PLC uses a robot to carry a 3D glue detection camera, and performs laser projection on the surface of the battery module after glue coating based on the glue coating trajectory. The colloid distribution law is fitted based on the degree of change of the reflected light on the surface of the battery module. The fitted colloid distribution law is compared with the standard colloid to determine whether the error is within the allowable deviation range. If so, a qualified test result is generated; if not, an unqualified test result is generated.

[0021] In a second aspect, the present invention provides a battery module automatic cleaning and gluing system, comprising the following modules:

[0022] Battery module transfer module, used for PLC-controlled AGV to transfer battery modules to the cleaning and gluing station;

[0023] The battery module verification module is used for the PLC to read the AGV vehicle number and the module number of the battery module, and verify the battery module based on the vehicle number and module number;

[0024] The battery module cleaning module is used to control the robot's quick-change plate to switch the plasma cleaning machine to the working position after the PLC locates the battery module through the 2D positioning camera installed on the robot. The robot then moves the plasma cleaning machine to automatically clean the battery module.

[0025] The battery module gluing module is used to control the robot's quick-change plate of the PLC to switch the gluing machine to the working position, and the robot moves the gluing machine to automatically apply glue to the battery module;

[0028] Furthermore, the battery module verification module is specifically used to:

[0029] The PLC reads the AGV trolley number and the module number of the battery module, matches the module number from the database based on the trolley number, and determines whether the module number matched by the database is consistent with the read module number. If so, the battery module verification passes and enters the battery module cleaning module; if not, the battery module verification fails and the process ends.

[0030] Furthermore, the battery module gluing module is specifically used for:

[0031] The PLC controls the robot's quick-change plate to switch the glue applicator to the working position. The robot uses a 2D positioning camera to take pictures of the battery module, obtain the module pictures, and transmit them to the PLC.

[0032] The PLC calculates the compensation value of the module position based on the module photo, corrects the preset gluing trajectory based on the compensation value, and sets the pause time, gluing pressure, gluing amount and moving speed of each gluing point in the gluing trajectory;

[0033] The PLC controls the glue coating machine through a robot to automatically apply glue to the battery module based on the glue coating trajectory.

[0034] Furthermore, the glue detection module is specifically used to:

[0035] The PLC uses a robot to carry a 3D glue detection camera, and performs laser projection on the surface of the battery module after glue coating based on the glue coating trajectory. The colloid distribution law is fitted based on the degree of change of the reflected light on the surface of the battery module. The fitted colloid distribution law is compared with the standard colloid to determine whether the error is within the allowable deviation range. If so, a qualified test result is generated; if not, an unqualified test result is generated.

[0039] The PLC controls the AGV trolley to move the battery module to the cleaning and gluing station, and reads the trolley number of the AGV trolley and the module number of the battery module. After verifying the battery module based on the trolley number and module number, the battery module is positioned by the 2D positioning camera, and the robot's quick-change plate is controlled to switch the plasma cleaning machine to the working position. The robot moves the plasma cleaning machine to automatically clean the battery module, and then controls the quick-change plate to switch the gluing machine to the working position. The robot moves the gluing machine to automatically gluing the battery module.

The 2D positioning camera records the battery module cleaning and gluing process to obtain the cleaning and gluing video, and sends the inspection results and the cleaning and gluing video to the MES terminal through the host computer for archiving. That is, the PLC switches the current working position of the plasma cleaning machine or the gluing machine through the quick-change disk. The plasma cleaning machine and the gluing machine are moved by the robot to automatically clean and gluing the battery module. The 3D glue type detection camera is used to automatically detect the gluing quality, thereby greatly improving the quality of battery module cleaning and gluing. Since the plasma cleaning machine and the gluing machine can be switched through the quick-change disk, only one control system is required, which greatly reduces costs.

[0047] The embodiments of the present application provide a method, system, equipment and medium for automatic cleaning and gluing of battery modules, thereby improving the quality and traceability of battery module cleaning and gluing and reducing costs.

[0048] The overall idea of ​​the technical solution in the embodiments of the present application is as follows: the battery module is automatically cleaned and glued by a robot-moving plasma cleaning machine and a glue coating machine, and the glue coating quality is automatically detected by a 3D glue type detection camera to improve the quality of battery module cleaning and gluing; the plasma cleaning machine and the glue coating machine are switched by a quick-change disk, and only one control system is required to reduce costs.

[0049] The present invention requires the use of a battery module automatic cleaning and gluing device as follows: Figure 5 As shown, it includes a PLC, an MES terminal, a host computer, an AGV car, a car control terminal, a touch screen, a robot, a 2D positioning camera, a 3D glue detection camera, a plasma cleaning machine, a glue coating machine, a wireless communication module and a quick-change plate. The PLC communicates and controls with other equipment via the Profinet bus to control the entire production process, establish various working modes such as first-article mode and robot maintenance mode, and monitor the entire production process in real time, including the operating data of other equipment.

[0050] One end of the host computer is connected to the PLC, and the other end is connected to the MES terminal; one end of the trolley control terminal is connected to the PLC, and the other end is connected to the AGV trolley; the PLC is respectively connected to the touch screen, robot, 2D positioning camera, 3D glue type detection camera, plasma cleaning machine, glue coating machine and wireless communication module; the plasma cleaning machine and glue coating machine are installed on the robot through a quick-change disk; the 2D positioning camera and 3D glue type detection camera are both installed on the robot.

[0051] The wireless communication module is at least one of a 2G communication module, a 3G communication module, a 4G communication module, a 5G communication module, an NB-IOT communication module, a LORA communication module, a WIFI communication module, a Bluetooth communication module or a ZigBee communication module.

[0052] Example 1

[0053] This embodiment provides a method for automatically cleaning and gluing a battery module. Figure 1 、 5 As shown, the following steps are included:

[0054] Step S10: PLC controls the AGV to move the battery module to the cleaning and gluing station;

[0055] Step S20: The PLC reads the AGV vehicle number and the module number of the battery module, and verifies the battery module based on the vehicle number and the module number.

[0056] In step S30, the PLC locates the battery module using the 2D positioning camera on the robot, then controls the robot's quick-change plate to switch the plasma cleaner to the working position. The robot then moves the plasma cleaner to automatically clean the battery module. Positioning using the 2D positioning camera eliminates the dangers caused by inaccurate mechanical positioning.

[0057] The quick-change plate is mainly composed of a quick-change frame and a quick-change hydraulic cylinder. By manipulating the solenoid valve handle to control the extension and contraction of the quick-change cylinder, you can achieve rapid switching and attach different tools, thus meeting the requirement of one machine for multiple uses.

[0058] Step S40: The PLC controls the robot's quick-change plate to switch the glue applicator to the working position. The robot moves the glue applicator to automatically apply glue to the battery module. Before applying glue, the glue applicator must be preheated to 140 degrees. When the inlet and outlet pressures of the glue applicator's glue pump reach 2500 psi, manual pressure relief is required.

[0059] The streamlined cleaning and gluing process allows for mid-stop operation, eliminating the need to restart from the beginning to save time. Software flags and hardware sensors jointly determine the device status, preventing accidents caused by hardware failures or software vulnerabilities.

[0060] In step S50, the PLC uses a 3D glue pattern inspection camera installed on the robot to inspect the glue coating quality of the battery module and generate an inspection result. The 3D glue pattern inspection camera performs glue coating quality inspection, realizes automated inspection, and can record data to eliminate manual judgment errors and facilitate data backtracking. The 3D glue pattern inspection camera can be a Keyence LJX8200.

[0061] Step S60: The PLC records the battery module cleaning and gluing process through a 2D positioning camera to obtain a cleaning and gluing video, and sends the detection results and the cleaning and gluing video to the MES terminal through the host computer for archiving.

[0062] The present invention integrates and upgrades the plasma cleaning machine and the glue coating machine to make them more intelligent, safer and more efficient. A control system is built with PLC as the control center. In conjunction with the quick-change disk, the robot can conveniently and efficiently switch between the plasma cleaning machine and the glue coating machine, making the workstation compatible with both processes.

[0063] The step S20 is specifically as follows:

[0064] The PLC reads the AGV trolley number and the module number of the battery module, matches the module number from the database based on the trolley number, and determines whether the module number matched by the database is consistent with the read module number. If so, the battery module verification passes and enters step S30; if not, the battery module verification fails and the process ends.

[0065] The step S40 is specifically as follows:

[0066] The PLC controls the robot's quick-change plate to switch the glue applicator to the working position. The robot uses a 2D positioning camera to take pictures of the battery module, obtain the module pictures, and transmit them to the PLC.

[0067] The PLC calculates the compensation value of the module position based on the module photo, corrects the preset gluing trajectory based on the compensation value, and sets the pause time, gluing pressure (gluing speed), gluing amount and moving speed of each gluing point in the gluing trajectory;

[0068] The PLC controls the glue applicator through a robot, automatically applying glue to the battery modules based on the glue application trajectory. The PLC records and times the glue application time with the host computer, which then communicates with the next process to ensure that the battery modules are packed within the effective glue application time.

[0069] During specific implementation, three working modes can be selected: separate cleaning, separate gluing, and gluing after cleaning.

[0070] The step S50 is specifically as follows:

[0071] The PLC uses a robot to carry a 3D glue detection camera, and performs laser projection on the surface of the battery module after glue coating based on the glue coating trajectory. The colloid distribution law is fitted based on the degree of change of the reflected light on the surface of the battery module. The fitted colloid distribution law is compared with the standard colloid to determine whether the error is within the allowable deviation range. If so, a qualified test result is generated; if not, an unqualified test result is generated.
