Description

Technical Field

[0001] This invention belongs to the field of battery cover assembly technology, and specifically relates to a battery cover film applicator and its working method. Background Technology

[0002] During the assembly of the battery cover, the explosion-proof sheet is an important component. To prevent the explosion-proof sheet from being damaged by external objects during the processing and production process, a protective film needs to be applied to its surface after welding. Originally, the film was applied manually, which required a lot of manpower, was inefficient, and had a large workload, which could not meet the needs of production.

[0003] Many companies currently use equipment for film application; however, problems such as misalignment and incorrect application can easily occur during the application process, leading to defective products.

[0004] Furthermore, many existing film application equipment use the same film application mechanism to take a complete mold before applying the film. The film application mechanism takes a long time during its stroke, which affects its film application efficiency.

[0005] Therefore, existing film application equipment still needs to be improved. Summary of the Invention

[0006] Purpose of the Invention: To overcome the above shortcomings, the purpose of this invention is to provide a battery cover film applicator with a simple structure, reasonable design, easy production, and high degree of automation. The structure of existing film applicators has been optimized. A clamping and limiting mechanism limits the battery cover assembly. In the film applicator, the first adsorption and transport component adsorbs and transports the protective film from the film supply mechanism to the secondary positioning mechanism for secondary positioning. Then, the first adsorption and transport component picks up the protective film from the film supply mechanism and places it on the secondary positioning mechanism for positioning. Finally, the second adsorption and film applicator component adsorbs and transports it from the secondary positioning mechanism to the top of the film applicator turntable fixture, completing the film applicator application. The entire film applicator process, through the cooperation of the first adsorption and transport component and the second adsorption and film applicator component, effectively shortens the film picking and applicator time. Furthermore, the secondary positioning mechanism and the clamping and limiting mechanism can respectively position the protective film and the battery cover assembly.

[0007] Technical solution: In order to achieve the above objectives, the present invention provides a battery cover film applicator, comprising: a film applicator frame, wherein a film applicator turntable is provided on the film applicator frame, and a film applicator turntable fixture is provided on the film applicator turntable;

[0012] A film application detection module is mounted on the film application machine frame and located behind the film application mechanism.

[0013] The feeding component is mounted on the film applicator frame and located behind the film applicator detection module. This invention provides a battery cover film applicator that optimizes the structure of existing film applicators. A clamping and limiting mechanism limits the battery cover assembly. In the film applicator, a first adsorption and transport component adsorbs and transports the protective film from the film supply mechanism to a secondary positioning mechanism for secondary positioning. Then, the first adsorption and transport component picks up the protective film from the film supply mechanism and places it on the secondary positioning mechanism for positioning. Finally, a second adsorption and film applicator component adsorbs and transports the film from the secondary positioning mechanism to the top of the film applicator turntable fixture, completing the film applicator application. The entire film applicator process, through the cooperation of the first and second adsorption and film applicator components, effectively shortens the film picking and applicator time.

The film-applying horizontal drive cylinder drives the template to move left and right, adjusting the distance between the two adsorption and transport components to meet the needs of film picking at different distances and film placement by the secondary positioning mechanism.

[0019] The second adsorption film assembly includes a U-shaped support frame, and the adsorption film assembly is provided on both supports of the U-shaped support frame.

Both the transverse clamping drive cylinder and the longitudinal clamping drive cylinder are located on the positioning middle plate. The transverse clamping plate is connected to the transverse clamping drive cylinder, and the longitudinal clamping plate is connected to the longitudinal clamping drive cylinder.

[0027] As can be seen from the above technical solution, the present invention has the following beneficial effects:

[0028] 1. The battery cover film applicator of the present invention optimizes the structure of existing film applicators. A clamping and limiting mechanism limits the battery cover assembly. In the film applicator, a first adsorption and transport component adsorbs and transports the protective film from the film supply mechanism to a secondary positioning mechanism for secondary positioning. Then, the first adsorption and transport component picks up the protective film from the film supply mechanism and places it on the secondary positioning mechanism for positioning. Finally, a second adsorption and film applicator component adsorbs and transports the film from the secondary positioning mechanism to the top of the film applicator turntable fixture, completing the film applicator application. The entire film applicator process, through the cooperation of the first adsorption and transport component and the second adsorption and film applicator component, effectively shortens the film picking and applicator time. Simultaneously, the secondary positioning mechanism and the clamping and limiting mechanism can respectively position the protective film and the battery cover assembly, effectively ensuring the accuracy of the protective film application and improving the yield rate.

[0029] 2. The positioning gripper assembly, driven by a positioning cylinder, positions the protective film, further improving the precision of film removal and application in the latter part of the second adsorption film application assembly.

[0030] 3. The first adsorption and transport assembly is controlled by the film-applying vertical plate to drive the entire film-applying horizontal drive cylinder, the template, the variable-distance base plate, and the adsorption and transport assembly in a coordinated manner. This allows the two sets of adsorption and transport assemblies to move up and down synchronously, ensuring that the two protective films are at the same level. The film-applying horizontal drive cylinder drives the template to move left and right, which can adjust the distance between the two adsorption and transport assemblies to meet the needs of film picking at different distances and film placement by the secondary positioning mechanism.

[0031] 4. The clamping and limiting mechanism, wherein the lateral clamping drive cylinder drives the lateral clamping plate to limit the lateral movement of the battery cover plate, and the longitudinal clamping drive cylinder drives the longitudinal clamping plate to limit the longitudinal movement of the two battery cover plate assemblies simultaneously, can effectively limit the battery cover plate assemblies and improve the film application accuracy.

[0061] The working method of the battery cover film applicator described in this embodiment is as follows: 1): First, the battery cover assembly processed in the previous process is conveyed to the feeding position through the battery cover feeding mechanism 81;

[0062] 2): The cover plate feeding mechanism 82 feeds the battery cover plate assembly. The horizontal moving module drives the feeding robot assembly 822 to move to the feeding position on the battery cover plate feeding mechanism 81. The barcode scanning assembly 83 scans the QR code on the product. The feeding lifting drive cylinder 8221 drives the suction cup assembly 8225 to descend above the product and pick up the product. Then, the feeding lifting drive cylinder 8221 drives the suction cup assembly 8225 to lift the product to the initial position. Then, the horizontal moving module drives the feeding robot assembly 822 to move to the film application turntable fixture. The feeding rotation drive cylinder 8222 drives the rotating column 8224 to rotate the suction cup assembly 8225 so that the product is aligned with the groove direction on the film application turntable fixture. Then, the feeding lifting drive cylinder 8221 drives the suction cup assembly 8225 to descend and place the product on the film application turntable fixture. The film application turntable drives the film application turntable fixture containing the product to rotate to the film application station.

[0063] 3) After the film-applying turntable fixture rotates into position, the clamping and limiting mechanism 855 will clamp and position the battery cover. That is, the lifting cylinder 8556 drives the positioning top plate 8553 to move the horizontal clamping plate 8554 and the vertical clamping plate 8555 on it upward together, so that they enter the horizontal and vertical through holes of the film-applying turntable fixture. The horizontal clamping drive cylinder 8557 and the vertical clamping drive cylinder 8558 adjust the position of the horizontal clamping plate 8554 and the vertical clamping plate 8555 respectively, so that they limit the horizontal and vertical position of the battery cover.

[0064] 4): The film feeding mechanism 84 feeds the protective film;

[0065] 5): The first adsorption and transport component 853 picks up the protective film. That is, according to the distance between the two protective films on the film supply mechanism 84, the film application horizontal drive cylinder 8533 drives the template 8534 to move the adsorption and transport component 8536 on it until the distance between the adsorption and transport component 8536 on the film application vertical plate 8532 and the adsorption and transport component 8536 on the template 8534 is the same as the distance between the two protective films. The film application lifting cylinder 8531 will drive the film application vertical plate 8532 to descend. Under the drive of the film application vertical plate 8532, the adsorption and transport component 8536 on the film application vertical plate 8532 and the adsorption and transport component 8536 on the template 8534 descend to the upper surface of the protective film at the same time, and pick up the corresponding protective film through the corresponding suction nozzle 85425.

[0066] 6): The moving module on the film mounting bracket 851 drives the film sliding block 852 to move. During the movement of the film sliding block 852, it will drive the first adsorption and transportation component 853, which has absorbed the protective film, to move together until the first adsorption and transportation component 853 moves above the secondary positioning mechanism 841.

[0067] 7): The positioning cylinder 84151 in the secondary positioning mechanism 841 drives the gripper 84152 to open, and the film-applying lifting cylinder 8531 drives the film-applying vertical plate 8532 to descend, placing the protective film onto the positioning support platform 8414.

[0068] 8): The secondary positioning mechanism 841 positions the protective film, that is, the positioning cylinder 84151 drives the gripper 84152 to position the protective film.

[0069] 9): During this process, the moving module on the film mounting bracket 851 drives the film sliding plate 852 to move. When the film sliding plate 852 moves, it drives the first adsorption and conveying component 853 and the second adsorption and film application component 854 to move together. The second adsorption and film application component 854 moves to above the secondary positioning mechanism 841, and the first adsorption and conveying component 853 moves to the feeding platform of the film supply mechanism 84.

[0070] 10): The positioning cylinder 84151 in the secondary positioning mechanism 841 drives the gripper 84152 to open, and the lifting drive cylinder 85421 in the second adsorption film application assembly 854 drives the slide plate 85423 to move the detection block 85424 and the suction nozzle 85425 downward. After the detection block 85424 detects the protective film, the suction nozzle 85425 sucks up the protective film, and the first adsorption and conveying assembly 853 picks up the protective film at the feeding platform of the film supply mechanism 84.

[0071] 11): The moving module on the film mounting bracket 851 drives the film-applying slider plate 852 to move. When the film-applying slider plate 852 moves, it drives the first adsorption and conveying component 853 and the second adsorption and film-applying component 854 to move together. The first adsorption and conveying component 853 picks up the protective film onto the secondary positioning mechanism 841. The second adsorption and film-applying component 854 moves the picked-up protective film to the top of the film-applying turntable fixture on the film-applying station. The detection pin on the detection block 85424 detects the position of the explosion-proof sheet on the battery cover. Then, the lifting drive cylinder 85421 drives the slide plate 85423 to drive the suction nozzle 85425 to move downward and apply the protective film to the corresponding position of the explosion-proof sheet.

[0072] 12): After the protective film is applied, the film application turntable drives the film application turntable fixture containing the product with the protective film applied to rotate to the inspection station. The film application inspection module 86 inspects the film application and transmits the inspection data to the data processing center for analysis.

[0073] 13): The film-applying turntable continues to rotate, moving the inspected product to the unloading station;

[0074] 14): Based on the detection results in step 12), the products are sorted and unloaded. Good products are picked up by the unloading robot assembly 871 and transported to the good product unloading conveyor 872 to the next workstation.

That is, the horizontal moving module drives the feeding robot assembly (822) to move to the feeding position on the battery cover plate feeding mechanism (81). The barcode scanning assembly (83) scans the QR code on the product. The feeding lifting drive cylinder (8221) drives the suction cup assembly (8225) to descend above the product and pick up the product. Then, the feeding lifting drive cylinder (8221) drives the suction cup assembly (8225) to lift the product to the initial position.

The second adsorption and film application component (854) moves to the upper part of the secondary positioning mechanism (841), and the first adsorption and conveying component (853) moves to the feeding platform of the film supply mechanism (84). 10): The positioning cylinder (84151) in the secondary positioning mechanism (841) drives the gripper (84152) to open, and the lifting drive cylinder (85421) in the second adsorption film application assembly (854) drives the slide plate (85423) to move the detection block (85424) and the suction nozzle (85425) downward. After the detection block (85424) detects the protective film, the suction nozzle (85425) sucks up the protective film, and the first adsorption transport assembly (853) picks up the protective film at the feeding platform of the film supply mechanism (84). 11): The moving module on the film mounting bracket (851) drives the film sliding block (852) to move. When the film sliding block (852) moves, it drives the first adsorption and conveying component (853) and the second adsorption and film application component (854) to move together. The first adsorption and conveying component (853) picks up the protective film onto the secondary positioning mechanism (841). The second adsorption and film application component (854) moves the picked-up protective film to the top of the film application turntable fixture on the film application station. The detection pin on the detection block (85424) detects the position of the explosion-proof sheet on the battery cover. Then, the lifting drive cylinder (85421) drives the slide plate (85423) to drive the suction nozzle (85425) to move down and apply the protective film to the corresponding position of the explosion-proof sheet. 12): After the protective film is applied, the film application turntable drives the film application turntable fixture containing the product with the protective film applied to rotate to the inspection station.
