Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to a fully automated assembly line for battery cover plates and stop frames. Background Technology

[0002] In the conventional assembly of battery cover and stop frame, the battery cover and stop frame are usually pressed together by a single pressing device. Before pressing, tape needs to be applied to the battery cover to ensure the pressing effect between the two. However, the feeding and tape application of the battery cover, and the feeding and positioning of the stop frame all require different equipment or manual operation, which greatly affects the assembly efficiency and increases the assembly cost.

[0003] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a fully automated assembly line for battery cover plates and stop frames, thereby effectively solving the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a fully automated assembly line for battery cover plates and stop frames, the assembly line comprising:

[0006] Battery cover plate feeding line, the battery cover plate is placed in the jig tray and conveyed on the battery cover plate feeding line;

[0007] The battery cover is transferred from the battery cover loading line to the loading transfer platform by the first transfer device.

[0008] Product position correction mechanism, located at the loading transfer table, is used to correct the placement state of the battery cover plate on the loading transfer table;

[0009] A battery cover conveyor line, wherein battery covers are transferred from the loading transfer platform to the battery cover conveyor line via a second transfer device;

[0010] An adhesive application assembly is installed on the conveying track of the battery cover conveyor line and is used to apply adhesive tape to the surface of the battery cover.

[0011] A hopper, wherein a stop frame is placed inside the hopper;

[0012] The pressing platform and the stop frame are transferred from the hopper to the pressing platform by the third transfer device. The battery cover is also transferred from the battery cover conveyor line to the pressing platform by the third transfer device.

[0013] The pressing module is used to press and assemble the battery cover and the stop bracket;

[0014] The product unloading conveyor line is used to unload the product after the battery cover and stop frame have been pressed together.

[0015] The beneficial effects of this invention are as follows: The fully automatic assembly line for battery cover and stop frame designed in this solution can automatically complete the feeding, conveying, and surface tape application of battery cover, as well as the feeding, positioning, and pressing assembly between battery cover and stop frame. It has a high degree of automation, integrates various functional equipment together, and can effectively improve work efficiency, reduce assembly costs, and accelerate the product assembly process.

[0016] Furthermore, the product position correction structure includes a detection component and an execution component. The detection component is used to detect the placement state of the battery cover, and the execution component is used to change the placement state of the battery cover.

[0017] Furthermore, the detection component includes a color sensor and a photoelectric sensor. The color sensor is used to detect the color of the front side of the battery cover, and the photoelectric sensor is used to detect the position of the circular hole on the surface of the battery cover. The front and back sides of the battery cover are different colors, so the color sensor can be used to detect whether the battery cover placed on the fixture is facing up or down. A circular hole is formed on the surface of the battery cover, near the upper part of the battery cover. The photoelectric sensor is located at a designated position and can be used to detect the circular hole. If the photoelectric sensor can detect the circular hole, it means that the battery cover is placed correctly. If the photoelectric sensor cannot detect the circular hole, it means that the battery cover is placed upside down.

[0018] Furthermore, the execution component includes a rotating suction cup and a flipping gripper. The rotating suction cup can rotate the battery cover to adjust its placement on the top and bottom of the fixture table, and the flipping gripper can flip the battery cover to adjust its placement on the front and back of the fixture table. The rotating suction cup can suck up the battery cover from the fixture table and then rotate it horizontally to correct the battery cover that is upside down. The flipping gripper can clamp the battery cover from the fixture table and flip it so that the battery cover is turned over and corrected so that the battery cover that was originally facing up is now facing up.

[0019] Furthermore, the tape application device includes a roll roller, a guide roller, an application wheel, and a cutter. The tape is wound on the roll roller, and the head of the tape is pulled out from the application wheel through the guide roller. The application wheel applies the tape to the surface of the battery cover, and the cutter cuts off the head of the tape. A limit stop is provided on the battery cover conveyor line, located at the tape application assembly. The battery cover is placed in the fixture plate of the conveyor line, and the limit stop is used to block the fixture plate on the conveyor line to ensure that the battery cover in the fixture plate remains stationary during tape application. When applying tape to the surface of the battery cover, the tape pulled out is applied to the surface of the battery cover by the application wheel, and then the tape can be cut into segments by the cutter. The tape application device uses existing equipment and is a publicly available technology, so its principle will not be described in detail.

[0020] Furthermore, the first transfer device includes a first suction cup for sucking the battery cover plate out of the battery cover plate loading line and placing it into the loading transfer table, and a first dual-axis drive module for driving the first suction cup to move.

[0021] The second transfer device includes a second suction cup for sucking the battery cover plate out of the loading transfer table and placing it into the battery cover plate conveyor line, and a second dual-axis drive module for driving the second suction cup to move.

[0022] The third transfer device includes a third suction cup for sucking the stop frame out of the hopper and placing it on the pressing platform, a fourth suction cup for sucking the battery cover plate out of the battery cover plate conveyor line and placing it on the pressing platform, and a third dual-axis drive module for moving the third suction cup and the fourth suction cup.

[0023] Furthermore, the second dual-axis drive module can drive the tape application device to move; multiple battery covers can be placed in a fixture plate, so the tape application device is moved by the second dual-axis drive module to ensure that the tape application device can apply tape to multiple battery covers in the fixture plate at the same time, and multiple parts of the surface of a battery cover need to be taped to ensure the pressing effect between it and the stop frame later.

[0024] Furthermore, the pressing module includes a mounting base and a retractable pressing column. The third dual-axis drive module drives the mounting base to move. The pressing column and the fourth suction cup are both mounted on the mounting base. The third dual-axis drive module drives the fourth suction cup to remove the battery cover from the jig tray of the conveyor line and place it on the pressing platform. At this time, a flipping gripper is also provided on one side of the pressing platform. The flipping gripper clamps the battery cover and flips it so that the side of the battery cover with tape is facing down and in contact with the stop frame. Then, driven by the rotating shaft, the flipping gripper can place the flipped battery cover back on the pressing platform, so that the battery cover and the stop frame are stacked together for final pressing. During pressing, the pressing column in the pressing module is mainly used to align and press the circular electrode sheet on the battery cover. The pressing module and the suction cup that picks up the battery cover share a drive module. The pressing column is extended and retracted by a telescopic cylinder. It extends during pressing and retracts when the suction cup picks up the battery cover to avoid affecting the normal operation of the suction cup.

[0025] Furthermore, the battery cover conveyor line includes two parallel conveyor tracks, and a material unloading transfer platform is provided at the end of the battery cover conveyor line. The second transfer device transfers the pressed product from the battery cover conveyor line to the material unloading transfer platform, and the first transfer device transfers the pressed product from the material unloading transfer platform to the product unloading conveyor line. After the stop frame and battery cover are pressed, the assembled product is sucked out from the pressing platform by the battery cover suction cup and placed back into the fixture tray of the battery cover conveyor line. Therefore, a double parallel track structure is required for cross conveying. When the fixture tray full of finished products returns from the conveyor line, it will not be blocked by the fixture tray conveying the battery cover.

[0026] Furthermore, a jig tray transfer line is provided between the battery cover plate loading line and the product unloading conveyor line; the jig tray transfer line provided between the battery cover plate loading line and the product unloading conveyor line can realize the cyclical use of the jig tray, as detailed below:

[0027] The jig trays filled with battery covers are stacked below the battery cover loading line. They are lifted one by one by a lifting structure. When a battery cover in a jig tray is completely removed, the empty tray is sucked out of the battery cover loading line by a suction cup and a dual-axis drive module and placed on the jig tray transfer line. The empty tray is then transported to the product unloading conveyor line via the jig tray transfer line. The empty trays on the unloading conveyor line are used to place the pressed products. The unloading conveyor line is also equipped with a lifting structure. The empty trays filled with products are lowered one by one by the lifting structure. The jig trays filled with products are stacked below the unloading conveyor line and then unloaded uniformly.

[0028] In summary, the fully automatic assembly line for battery cover and stop frame designed in this scheme works as follows: the battery cover is placed on the jig tray and conveyed on the battery cover loading line, and then the battery cover is transferred from the battery cover loading line to the loading transfer table by the first transfer device.

[0029] A color sensor on the transfer platform is used to detect the color of the front of the battery cover. Since the front and back of the battery cover are different colors, the color sensor can be used to detect whether the battery cover placed on the fixture is facing up or down. A circular hole is made on the surface of the battery cover, near the top of the battery cover. The photoelectric sensor is located at a designated position and can be used to detect the circular hole. If the photoelectric sensor can detect the circular hole, it means that the battery cover is placed correctly. If the photoelectric sensor cannot detect the circular hole, it means that the battery cover is placed upside down.

[0030] When the battery cover is upside down, the suction cup can be rotated to pick up the battery cover from the fixture table, and then rotated horizontally to correct the upside-down battery cover. When the battery cover is facing upside down, the flip gripper can be used to pick up the battery cover from the fixture table and flip it over, so that the battery cover is corrected from facing upside down to facing upside down.

[0031] The loading transfer platform extends forward parallel to the battery cover conveyor line. After the battery cover is inspected and its position is corrected, it is transferred from the loading transfer platform to the battery cover conveyor line by the second transfer device. Then, the tape applicator applies tape to the surface of the battery cover. After the tape is applied, the fixture tray moves the battery cover to the end of the battery cover conveyor line.

[0032] The hopper filled with stop frames moves sequentially to the designated position on the hopper conveyor line, and then the third suction cup pulls the stop frames out of the hopper and places them on the pressing platform;

[0033] Meanwhile, the third dual-axis drive module drives the fourth suction cup to remove the battery cover from the jig tray of the conveyor line and place it on the pressing platform. At this time, a flipping gripper is also set on one side of the pressing platform. The flipping gripper clamps the battery cover out and flips it so that the side of the battery cover with tape is facing down and in contact with the stop frame. Then, driven by the rotating shaft, the flipping gripper can put the flipped battery cover back on the pressing platform, so that the battery cover and the stop frame are stacked together and waiting for final pressing. During pressing, the pressing column in the pressing module is aligned with the circular electrode sheet on the battery cover for pressing. The pressing module and the suction cup that picks up the battery cover share a drive module. The pressing column is extended and retracted by a telescopic cylinder. It extends during pressing and retracts when the suction cup picks up the battery cover to avoid affecting the normal operation of the suction cup.

[0034] The pressed products are sucked out by the fourth suction cup and driven by the third drive module to be put back into the empty fixture tray of the battery cover conveyor line. When the fixture tray is full of products, the fixture tray moves to the end of the battery cover conveyor line. Then the second suction cup sucks out the products in the fixture tray and puts them into the unloading transfer table. The flipping gripper flips the products over. Then the first suction cup sucks out the flipped products from the transfer platform and puts them into the empty fixture tray on the product unloading conveyor line. When the empty fixture is full, it is lowered by the lifting mechanism and unloaded uniformly from below the product unloading conveyor line.

[0035] The fully automated assembly line designed in this scheme can automatically complete the feeding, conveying, and surface tape application of battery cover plates, as well as the feeding, positioning, and pressing assembly of battery cover plates and stop frames. It has a high degree of automation, integrating various functional devices together, which can effectively improve work efficiency, reduce assembly costs, and accelerate the product assembly process.

[0057] This solution designs a fully automated assembly line for battery covers and stop frames. It can automatically complete the feeding, conveying, and surface tape application of battery covers, as well as the feeding, positioning, and pressing assembly of the battery covers and stop frames. It has a high degree of automation, integrating various functional devices together, which can effectively improve work efficiency, reduce assembly costs, and accelerate the product assembly process.

[0058] In one or more embodiments, the product position correction structure includes a detection component and an execution component, the detection component being used to detect the placement state of the battery cover, and the execution component being used to change the placement state of the battery cover.

[0059] The detection component includes a color sensor 4.1 and a photoelectric sensor 4.2. The color sensor 4.1 is used to detect the color of the front of the battery cover, and the photoelectric sensor 4.2 is used to detect the position of the circular hole on the surface of the battery cover.

[0060] The front and back of the battery cover are different colors, so the color sensor 4.1 can be used to detect whether the battery cover placed on the fixture is facing up or down. A circular hole is made on the surface of the battery cover, near the top of the battery cover. The photoelectric sensor 4.2 is in a designated position and can be used to detect the circular hole. If the photoelectric sensor 4.2 can detect the circular hole, it means that the battery cover is placed correctly. If the photoelectric sensor 4.2 cannot detect the circular hole, it means that the battery cover is placed upside down.

[0061] In one or more embodiments, the actuating component includes a rotating suction cup 4.3 and a flipping gripper 4.4, the rotating suction cup 4.3 being able to rotate the battery cover to adjust its placement on the top and bottom of the fixture table, and the flipping gripper 4.4 being able to flip the battery cover to adjust its placement on the front and back of the fixture table.

[0062] The rotating suction cup 4.3 can suck up the battery cover on the fixture table and then rotate it horizontally to correct the battery cover that is upside down; the flipping gripper 4.4 can clamp the battery cover on the fixture table and flip it over, so that the battery cover that was originally facing up is corrected to face up.

[0063] In one or more embodiments, the tape applicator includes a roll roller 7.1, a guide roller 7.2, an applicator wheel 7.3, and a cutter. The tape is wound on the roll roller 7.1, and the head of the tape is pulled out from the applicator wheel 7.3 through the guide roller 7.2. The applicator wheel 7.3 applies the tape to the surface of the battery cover plate, and the cutter cuts off the head of the tape.

[0064] A limit stop is provided on the battery cover conveyor line 5. The limit stop is located at the adhesive application component 7. The battery cover is placed inside the fixture plate of the conveyor line. The limit stop is used to block the fixture plate on the conveyor line to ensure that the battery cover inside the fixture plate remains stationary during adhesive application. When the adhesive tape device applies adhesive to the surface of the battery cover, the tape is pulled out and attached to the surface of the battery cover by the adhesive application roller 7.3. Then, the tape can be cut into segments by the cutter. The adhesive application device uses existing equipment and is a publicly available technology, so its principle will not be described in detail.

[0065] In one or more embodiments, the first transfer device 3 includes a first suction cup 3.1 for sucking the battery cover plate from the battery cover plate loading line 1 and placing it into the loading transfer table 2, and a first dual-axis drive module 3.2 for driving the first suction cup 3.1 to move.

[0066] The second transfer device 6 includes a second suction cup 6.1 for sucking the battery cover plate out of the loading transfer table 2 and placing it into the battery cover plate conveyor line 5, and a second dual-axis drive module 6.2 for driving the second suction cup 6.1 to move.

[0067] The third transfer device 10 includes a third suction cup 10.1 for sucking the stop frame out of the hopper 8 and placing it on the pressing platform 9, a fourth suction cup 10.3 for sucking the battery cover plate out of the battery cover plate conveyor line 5 and placing it on the pressing platform 9, and a third dual-axis drive module 10.2 for moving the third suction cup 10.1 and the fourth suction cup 10.3.

[0068] In one or more embodiments, the second dual-axis drive module 6.2 can drive the tape applicator to move.

[0069] Multiple battery covers can be placed in a single fixture plate. Therefore, the tape application device is moved by the second dual-axis drive module 6.2 to ensure that the tape application device can apply tape to multiple battery covers in the fixture plate at the same time. Furthermore, multiple parts of the surface of a single battery cover need to be taped to ensure the subsequent pressing effect with the stop frame.

[0070] In one or more embodiments, the pressing module 11 includes a mounting base 11.1 and a retractable pressing column 11.2. The third dual-axis drive module 10.2 drives the mounting base 11.1 to move. The pressing column 11.2 and the fourth suction cup 10.3 are both disposed on the mounting base 11.1.

[0071] The third dual-axis drive module 10.2 drives the fourth suction cup 10.3 to remove the battery cover from the jig tray of the conveyor line and place it on the pressing platform 9. At this time, a flipping gripper 4.4 is also provided on one side of the pressing platform 9. The flipping gripper 4.4 clamps the battery cover and flips it so that the side of the battery cover with tape is facing down and in contact with the stop frame. Then, driven by the rotating shaft 4.5, the flipping gripper 4.4 can put the flipped battery cover back on the pressing platform 9, so that the battery cover and the stop frame are stacked together and waiting for final pressing. During pressing, the pressing column 11.2 in the pressing module 11 is mainly used to align and press the circular electrode sheet on the battery cover. The pressing module 11 and the suction cup that picks up the battery cover share a drive module. The pressing column 11.2 is extended and retracted by a telescopic cylinder. It extends during pressing and retracts when the suction cup picks up the battery cover to avoid affecting the normal operation of the suction cup.

[0072] In one or more embodiments, the battery cover conveyor line 5 includes two parallel conveyor tracks, and a discharge transfer station 12 is provided at the end of the battery cover conveyor line 5. The second transfer device 6 transfers the pressed product from the battery cover conveyor line 5 to the discharge transfer station 12, and the first transfer device 3 transfers the pressed product from the discharge transfer station 12 to the product discharge conveyor line 13.

[0073] After the stop frame and battery cover are pressed, the assembled product is sucked out from the pressing platform 9 by the battery cover suction cup and put back into the fixture tray of the battery cover conveyor line 5. Therefore, a double parallel track structure is required for cross conveying. When the fixture tray full of finished products returns from the conveyor line, it will not be blocked by the fixture tray conveying the battery cover.

[0074] In one or more embodiments, a jig tray transfer line 14 is provided between the battery cover loading line 1 and the product unloading conveyor line 13.

[0075] The fixture tray transfer line 14, located between the battery cover loading line 1 and the product unloading conveyor line 13, enables the cyclical use of the fixture tray, as detailed below:

[0076] The jig trays filled with battery covers are stacked below the battery cover loading line 1. They are lifted one by one by a lifting structure. When a battery cover in a jig tray is completely removed, the empty tray is sucked out of the battery cover loading line 1 by the jig tray suction cup module 15 in conjunction with the dual-axis drive module and placed on the jig tray transfer line 14. The empty tray is transported to the product unloading conveyor line 13 by the jig tray transfer line 14. The empty trays on the unloading conveyor line are used to place the pressed products. The unloading conveyor line is also equipped with a lifting structure. The empty trays filled with products are lowered one by one by the lifting structure. The jig trays filled with products are stacked below the unloading conveyor line and then unloaded uniformly.

[0077] In summary, the specific working principle of this equipment is as follows: the battery cover is placed on the jig tray and conveyed on the battery cover loading line 1, and then the battery cover is transferred from the battery cover loading line 1 to the loading transfer table 2 by the first transfer device 3;

[0078] Color sensor 4.1 on the transfer platform is used to detect the color of the front of the battery cover. Since the front and back of the battery cover are different colors, color sensor 4.1 can be used to detect whether the battery cover placed on the fixture is facing up or down. A circular hole is opened on the surface of the battery cover, near the upper part of the battery cover. Photoelectric sensor 4.2 is in a designated position and can be used to detect the circular hole. If photoelectric sensor 4.2 can detect the circular hole, it means that the battery cover is placed correctly. If photoelectric sensor 4.2 cannot detect the circular hole, it means that the battery cover is placed upside down.

[0079] When the battery cover is upside down, rotating the suction cup 4.3 can suck the battery cover out of the fixture table, and then rotating it horizontally can correct the upside-down battery cover. When the battery cover is facing upside down, flipping the gripper 4.4 can clamp the battery cover out of the fixture table and flip it over, so that the battery cover is corrected from facing upside down to facing upside down.

[0080] The loading transfer platform extends forward parallel to the battery cover conveyor line 5. After the battery cover is inspected and its position is corrected, it is transferred from the loading transfer platform to the battery cover conveyor line 5 by the second transfer device 6. Then, the tape applicator applies tape to the surface of the battery cover. After the tape is applied, the fixture tray moves the battery cover to the end of the battery cover conveyor line 5.

[0081] The hopper 8 filled with stop frames moves sequentially to the designated position on the hopper 8 conveyor line, and then the third suction cup 10.1 sucks the stop frames out of the hopper 8 and places them on the pressing platform 9;

[0082] Meanwhile, the third dual-axis drive module 10.2 drives the fourth suction cup 10.3 to remove the battery cover from the jig tray of the conveyor line and place it on the pressing platform 9. At this time, a flipping gripper 4.4 is also provided on one side of the pressing platform 9. The flipping gripper 4.4 clamps the battery cover and flips it so that the side of the battery cover with tape is facing down and in contact with the stop frame. Then, driven by the rotating shaft 4.5, the flipping gripper 4.4 can place the flipped battery cover back on the pressing platform 9, so that the battery cover and the stop frame are stacked together and waiting for final pressing. During pressing, the pressing column 11.2 in the pressing module 11 is mainly used to align and press the circular electrode sheet on the battery cover. The pressing module 11 and the suction cup that picks up the battery cover share a drive module. The pressing column 11.2 is extended and retracted by a telescopic cylinder. It extends during pressing and retracts when the suction cup picks up the battery cover to avoid affecting the normal operation of the suction cup.

[0083] The pressed product is sucked out by the fourth suction cup 10.3 and driven by the third drive module to be put back into the empty fixture tray of the battery cover conveyor line 5. When the fixture tray is full of products, the fixture tray moves to the end of the battery cover conveyor line 5. Then the second suction cup 6.1 sucks out the products in the fixture tray and puts them into the unloading transfer table 12. The flipping gripper 4.4 flips the products over. Then the first suction cup 3.1 sucks out the flipped products from the transfer platform and puts them into the empty fixture tray on the product unloading conveyor line 13. When the empty fixture is full, it is lowered by the lifting mechanism and unloaded uniformly from below the product unloading conveyor line 13.

[0084] This fully automated assembly line can automatically complete the feeding, conveying, and surface tape application of battery cover plates, as well as the feeding, positioning, and pressing assembly of battery cover plates and pressing frames. Simultaneously, it can correct the position of the battery cover plates throughout the assembly process to ensure the accuracy of the pressed product.
