Description

Technical Field

[0001] This invention relates to the field of battery production equipment technology, and in particular to an automatic assembly equipment and production line for aluminum extruded battery casings. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the positive and negative electrode materials and a non-aqueous electrolyte solution. Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries typically use manganese dioxide as the positive electrode material, metallic lithium or its alloys as the negative electrode material, and a non-aqueous electrolyte solution. Lithium-ion batteries, on the other hand, typically use lithium alloy metal oxides as the positive electrode material, graphite as the negative electrode material, and a non-aqueous electrolyte solution. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

[0003] Lithium-ion batteries consist of a casing, cells, and a cover. The cells are housed within the casing, and the cover seals the casing. When lithium-ion batteries are used improperly, such as through overcharging, short circuits, or overheating, gas can be generated inside, causing increased internal pressure and potentially leading to an explosion. To address these issues, existing lithium-ion batteries, in addition to protective circuitry, incorporate an explosion-proof component on the top of the casing. This component primarily consists of a top cover and an explosion-proof plate. A safety hole is created on the top cover, and the explosion-proof plate covers this hole. The plate is then seamlessly sealed to the top cover using laser welding or adhesive bonding. The top cover is welded or secured to the top opening of the battery casing. The explosion-proof plate's function is to release pressure and reduce the risk of explosion when the internal pressure increases to a certain level during an abnormality in the lithium-ion battery.

[0004] In existing battery casing assembly processes, the explosion-proof plate must first be welded and fixed to the safety opening on the top cover, and then the top cover with the explosion-proof plate is welded and fixed to the opening on the top of the casing. This separate assembly process is quite cumbersome. If the welding position of the top cover is off, it will affect the installation position of the entire explosion-proof component. Moreover, most of the existing assembly operations require manual alignment welding, which is not only inefficient but also cannot ensure the accuracy of the welding position, affecting the quality of battery production. Since the aluminum extruded casing refers to a battery casing formed by extruding aluminum material, it has a hollow integrated structure. During the extrusion process, the top of the aluminum extruded casing has a safety opening for placing the explosion-proof plate, and the end of the aluminum extruded casing has an opening for placing the battery. During assembly, there is no need to perform the top cover operation again, nor is there a need for repeated alignment of the explosion-proof plate and the top cover. Only the two ends of the aluminum extruded casing need to be sealed, which improves the assembly efficiency.

[0005] Referring to Chinese invention patent publication number "CN119703471B" entitled "A Welding Equipment for Explosion-Proof Sheets on Circular Battery Covers," this technical solution discloses "a welding equipment for explosion-proof sheets on circular battery covers, comprising: a positioning fixture, which has a placement groove adapted to the shape of the battery cover, and a plurality of vacuum suction holes at the bottom of the placement groove, at least one of which is directly opposite the position of the groove; a transfer device, which is used to sequentially and cyclically transfer the positioning fixture to various workstations; a battery cover feeding device, which is used to transport the battery cover to the placement groove; an explosion-proof sheet feeding device, which is used to transport the explosion-proof sheet onto the battery cover; a welding device, which is used to weld the explosion-proof sheet onto the battery cover; and a unloading device, which is used to transfer the welded battery cover out of the positioning fixture." Although this technical solution can achieve automated welding of explosion-proof sheets and battery covers, after welding the explosion-proof sheet onto the battery cover, the battery cover still needs to be fixed to the battery casing, and it cannot be applied to welding explosion-proof sheets onto integrated aluminum extruded shells.

[0006] Therefore, how to automate the assembly of explosion-proof sheets into aluminum extruded shells is a technical problem that technicians need to solve. Summary of the Invention

[0037] The following is in conjunction with the appendix Figures 1 to 6 The technical solutions of the embodiments of this application are described in detail.

[0038] In Example 1, to automate the assembly of explosion-proof sheets for integrated aluminum extrusion battery casings, the existing battery casing assembly process requires welding the explosion-proof sheet to the safety opening of the casing cover plate and then welding the casing cover plate with the explosion-proof sheet to the opening of the battery casing. This is not only cumbersome but also requires multiple positioning and assembly steps, and manual operation is also necessary during the assembly process, resulting in low work efficiency. To improve work efficiency and make it suitable for the assembly of integrated aluminum extrusion battery casings, this example includes: a circular conveyor belt 1, a casing placement device 2, a sheet-swinging device 3, a welding device 4, and a material unloading device 5. The casing placement device 2 and the sheet-swinging device 3 are both located on the outer side near the circular conveyor belt 1, while the welding device 4 and the material unloading device 5 are both located on the other side near the circular conveyor belt 1. Several placement plates 11 are provided on the circular conveyor belt 1, and supporting vertical plates 12 are provided on the placement plates 11, with one side of the supporting vertical plates 12 facing the casing placement device 2. One side is provided with a strip tray 13 for fitting aluminum extruded housings. A pressing mechanism 6 is provided on the outside of the strip tray 13. A housing placement device 2 is used to place the aluminum extruded housings to be assembled on the strip tray 13. The pressing mechanism 6 is used to press the aluminum extruded housings. A swaying device 3 is used to place the explosion-proof sheets to be assembled on the aluminum extruded housings. A welding device 4 is adjacent to the swaying device 3 and is used to weld the explosion-proof sheets on the aluminum extruded housings. A material unloading device 5 is used to transport the assembled aluminum extruded housings. The housing placement device 2 effectively realizes the automated placement of aluminum extruded housings on the strip tray 13. The pressing mechanism 6 ensures that the aluminum extruded housings on the strip tray 13 are in a stable position. The swaying device 3 realizes the automated placement of explosion-proof sheets in the safety opening of the aluminum extruded housings. The aluminum extruded housings with explosion-proof sheets are transported to the welding device by the circular conveyor belt 1. The welding device 4 realizes the automatic welding action, thereby completing the assembly of the battery casing. This improves work efficiency and ensures that the position does not shift, thus ensuring production quality.

[0039] In addition to this embodiment, a flattening device can be provided outside the annular conveyor belt 1. The flattening device is located near the outside of the swing plate device 3. After the explosion-proof sheet is placed in the safety opening of the aluminum extrusion shell by the swing plate device 3, the explosion-proof sheet in the safety opening of the flattening device can be pressed down to ensure that the explosion-proof sheet is flush with the safety opening of the aluminum extrusion shell when entering the welding station.

[0040] Further supplementary information is needed for this embodiment: the unloading device 5 includes an unloading gripper 51 and a transverse moving module 52. A longitudinal moving module 53 is provided on the moving block of the transverse moving module 52, and a support plate 54 is provided on the power output end of the longitudinal moving module 53, so that the unloading gripper 51 is fixed directly below the support plate 54. One end of the transverse moving module 52 is brought close to the annular conveyor belt 1. After the aluminum extruded shell and the explosion-proof sheet are assembled, it is necessary to remove the assembled battery shell placed on the plate 11, which can be done through the transverse moving module 52.

[0041] To further supplement the above description, the welding device 4 includes a displacement mechanism and a welding gun head. The welding gun head is fixed on the moving end of the displacement mechanism, so that the displacement mechanism is located directly above the placement plate 11, and the end of the welding gun head is aligned with the placement plate 11. Therefore, the displacement mechanism can be used to control the movement range of the welding gun head. When the annular conveyor belt 1 transports the placement plate 11 to the welding device 4, and the strip support plate 13 is aligned with the end of the welding gun head, the displacement mechanism can drive the welding gun head to move and align the end of the welding gun head with the position to be welded, thereby achieving the welding and fixing of the explosion-proof sheet on the safety opening of the aluminum extruded shell.

[0042] In Example 2, to automate the loading and unloading of aluminum extruded shells into the shell-laying device 2, and to place the aluminum extruded shells to be assembled onto the strip pallet 13 using the shell-laying device 2, ensuring that the opening of the aluminum extruded shell is aligned with the strip pallet 13 during placement so that the aluminum extruded shell can be fitted onto the strip pallet 13, this example includes: a circular conveyor belt 1, a shell-laying device 2, a sheet-swinging device 3, a welding device 4, and a material unloading device 5; the shell-laying device 2 and the sheet-swinging device 3 are both located near the circular conveyor belt 1. On one side of the outer side of the conveyor belt 1, the welding device 4 and the unloading device 5 are both located near the other side of the annular conveyor belt 1. Several placement plates 11 are set on the annular conveyor belt 1, and support vertical plates 12 are set on the placement plates 11. One side of the support vertical plates 12 faces the shell-dispensing device 2. A strip-shaped support plate 13 for aluminum extrusion shells is set on one side of the support vertical plates 12. A pressing mechanism 6 is set on the outside of the strip-shaped support plate 13. A shell-removing device 7 is set on the outside of the shell-dispensing device 2. The shell-retrieving device 7 includes a linear motion module 71 and a lifting mechanism 72. The lifting mechanism 72 is mounted on the moving block of the linear motion module 71, with one end of the linear motion module 71 positioned directly above the shell-dispensing device 2. A lifting plate 73 is mounted on the power output end of the lifting mechanism 72, and at least one shell-retrieving gripper 74 is mounted on the bottom of the lifting plate 73. Therefore, the shell-retrieving device 7 can be used to place the aluminum extruded shells to be assembled onto the shell-dispensing device 2. During the material retrieval process, the linear motion module 71... The lifting mechanism 72 is moved to the top of the aluminum extrusion shell to be assembled. The lifting mechanism 72 then moves the lifting plate 73 down close to the aluminum extrusion shell until the aluminum extrusion shell to be assembled is within the clamping surface of the shell-removing gripper 74. The shell-removing gripper 74 clamps and grabs the aluminum extrusion shell. The lifting mechanism 72 then moves the lifting plate 73 up again. The linear motion module 71 then moves the shell-removing gripper 74, which is holding the aluminum extrusion shell, toward the shell-dispensing device 2, completing the automatic material handling action.

[0043] The aluminum extruded shells to be assembled can be placed on the strip pallet 13 using the shell placement device 2. The shell placement device 2 includes a reciprocating moving module 21. One end of the reciprocating moving module 21 is placed near the top of the annular conveyor belt 1, and the other end is placed near the shell removal device 7. A moving plate 22 is provided on the moving block of the reciprocating moving module 21, and a lifting cylinder 23 is provided on the outside of the moving plate 22. A shell placement gripper 24 is provided on the power output end of the lifting cylinder 23, and a supporting base plate 25 is provided at the bottom of the shell placement gripper 24, with one side of the supporting base plate 25 facing the gripping surface of the shell placement gripper 24. The reciprocating moving module 21 drives the moving plate 24 to move the aluminum extruded shells to be assembled onto the strip pallet 13. The moving plate 22 moves, and when the moving plate 22 is aligned with one end of the linear moving module 71, the linear moving module 71 can drive the shell-removing clamping finger 74, which is holding the aluminum extruded shell to be assembled, to move above the moving plate 22. The lifting mechanism 72 drives the shell-removing clamping finger 74 to approach the shell-placing clamping finger 24 on the moving plate 22, so that the bottom of the aluminum extruded shell is in the support base plate 25. The shell-removing clamping finger 74 releases its grip, and the linear moving module 71 and the lifting mechanism 72 reset and repeat the above actions. The shell-placing clamping finger 24 clamps the aluminum extruded shell on the support base plate 25, and the reciprocating moving module 21 drives the moving plate 22 to move toward the placement plate 11 on the annular conveying plane.

[0044] The support base plate 25 supports the aluminum extrusion shell and ensures that the aluminum extrusion shell remains stable when it is raised, and will not tilt due to insufficient clamping force of the shell release clamp. The support base plate 25 is provided on the clamping surface of the shell release clamp finger 24. The support base plate 25 supports the bottom of the aluminum extrusion shell and prevents the aluminum extrusion shell from tilting during the process of raising and lowering to align with the strip pallet 13.

[0045] When the placement plate 11 is aligned with one end of the reciprocating moving module 21, the reciprocating moving module 21 can move the shell-dispensing finger 24 holding the aluminum extruded shell toward the placement plate 11. During the movement, the lifting height of the shell-dispensing finger 24 can be adjusted by the lifting cylinder 23 to ensure that the end opening of the aluminum extruded shell on the shell-dispensing finger 24 is aligned with the strip tray 13. When the aluminum extruded shell is completely fitted onto the strip tray 13, the shell-dispensing clamping force is released, the reciprocating moving module 21 is reset and the above action is repeated. This effectively realizes the continuous placement of aluminum extruded shells to be assembled on the strip tray 13. It is suitable for placing aluminum extruded shells of different sizes and ensures that the aluminum extruded shells will not directly collide with the strip tray 13 during the placement process, effectively improving work efficiency.

[0046] In addition, it should be further noted that both the release clamping finger 24 and the take-out clamping finger 74 are equipped with clamping vertical plates. The opposite sides of the two clamping vertical plates form a clamping surface for clamping the aluminum extruded shell. Both the release clamping finger 24 and the take-out clamping finger 74 can be pneumatic clamping fingers, which are actuators that use compressed air as power to clamp or grasp workpieces. Their main function is to replace manual grasping work, which can effectively improve production efficiency and work safety. During the clamping process, the contact area can be increased by the clamping vertical plates to ensure that the force-bearing area is increased when clamping the aluminum extruded shell, thus ensuring stable clamping.

[0047] In Example 3, to ensure that the aluminum extruded shells on the placement plate 11, which is to be placed on a circular conveyor, do not sway and shift or tilt when being conveyed to subsequent processes, this embodiment includes: a circular conveyor belt 1, a shell-discharging device 2, a sheet-swinging device 3, a welding device 4, and a material-dropping device 5; the shell-discharging device 2 and the sheet-swinging device 3 are both located on the outer side near the circular conveyor belt 1. The system consists of several placement plates 11 on a circular conveyor belt 1, with supporting vertical plates 12 on each plate. One side of the supporting vertical plates 12 faces the shell-laying device 2. A strip-shaped pallet 13 for fitting aluminum extruded shells is provided on one side of the supporting vertical plates 12. A pressing mechanism 6 is provided on the outside of the strip-shaped pallet 13. The aluminum extruded shells to be assembled can be placed on the strip-shaped pallet 13 by the shell-laying device 2. An explosion-proof plate can be placed in the safety opening of the aluminum extruded shell by the swing plate device 3. When an aluminum extruded shell is fitted on the strip-shaped pallet 13, the pressing mechanism 6 can fix the aluminum extruded shell to ensure that the aluminum extruded shell remains in a stable position when it is conveyed into the subsequent process.

[0048] In this embodiment, the pressing mechanism 6 includes a pressing cylinder 61 and a fixed vertical plate 62. A lifting slide plate 63 is slidably disposed on the outside of the fixed vertical plate 62, and a pressing plate 64 is disposed on the top of the lifting slide plate 63. The pressing plate 64 is located on the top of the strip support plate 13. The power output end of the pressing cylinder 61 is fixedly connected to the bottom of the lifting slide plate 63, thereby controlling the lifting height of the lifting slide plate 63 through the pressing cylinder 61. When the shell placement device 2 places the aluminum extruded shell to be assembled on the plate 11, the power output end of the pressing cylinder 61 can retract and drive the pressing plate 64 toward the strip support plate 13. The aluminum extrusion shell moves until the pressing plate 64 contacts the aluminum extrusion shell on the placement plate 11, completing the automatic pressing action of the aluminum extrusion shell. This effectively ensures that the aluminum extrusion shell will not shake when the circular conveyor belt 1 transports the placement plate 11 into the subsequent work station. This ensures that when the explosion-proof sheet is placed, it is aligned with the safety opening of the aluminum extrusion shell and will not fall out when placed in the safety opening of the aluminum extrusion shell. The strip support plate 13 can support the explosion-proof sheet in the safety opening. In the subsequent welding process, it ensures that the aluminum extrusion shell will not shake and the explosion-proof sheet will not fall out, thus ensuring the assembly production quality.

[0049] In addition, to ensure that the pressing plate 64 does not block the safety opening of the aluminum extrusion shell when pressing it on the strip support plate 13, and to ensure stable pressing, a strip opening can be provided on the pressing plate 64, and the position of the strip opening can be aligned with the position of the safety opening of the aluminum extrusion shell. In this way, when the pressing plate 64 presses down on the aluminum extrusion shell, it will not block the safety opening, so as to facilitate the subsequent placement of the explosion-proof sheet and welding fixation.

[0050] In this embodiment, it should be further described that a straightening mechanism 8 is provided between the shell-laying device 2 and the slab-swinging device 3. The straightening mechanism 8 includes a mounting plate 81 and a pushing cylinder 82. The pushing cylinder 82 is located outside the mounting plate 81. A straightening plate 83 is provided on the power output end of the pushing cylinder 82, with one side of the straightening plate 83 facing the strip tray 13. A straightening protrusion 84 is provided on one side of the straightening plate 83, which is adapted to the safety opening of the aluminum extruded shell. When the shell-laying device 2 places the aluminum extruded shell to be assembled on the strip tray 13, the placing plate is transported by the annular conveyor belt 1. 11 is conveyed to the straightening mechanism 8 until the strip pallet 13 is aligned with the straightening plate 83. Then the clamping mechanism 6 is released. When the power output end of the push cylinder 82 retracts, the straightening plate 83 moves closer to the aluminum extruded shell on the strip pallet 13 until the straightening protrusion 84 enters the safety opening of the aluminum extruded shell. During this process, the aluminum extruded shell on the strip pallet 13 can be straightened. After the straightening action is completed, the power output end of the push cylinder 82 is reset, and the clamping mechanism 6 clamps the aluminum extruded shell on the strip pallet 13 again to ensure that the safety opening of the aluminum extruded shell is in the same position before entering the subsequent swaying device 3 for the placement of the explosion-proof sheet.

[0051] Example 4: To automate the picking and placing of explosion-proof sheets into the safety opening of the aluminum extrusion shell, and to perform correction operations on the explosion-proof sheets, the existing explosion-proof sheets are placed manually during the feeding process. Manual placement is inefficient and cannot ensure that the explosion-proof sheets are accurately positioned within the safety opening. Therefore, to improve work efficiency and ensure accurate placement, this example includes: a circular conveyor belt 1, a shell-discharging device 2, a sheet-swinging device 3, a welding device 4, and a dropping device 5. The shell-discharging device 2 and the sheet-swinging device 3 are both located on the outer side near the circular conveyor belt 1, and the welding... Device 4 and unloading device 5 are both located on the other side of the circular conveyor belt 1. Several placement plates 11 are provided on the circular conveyor belt 1. Supporting vertical plates 12 are provided on the placement plates 11. One side of the supporting vertical plates 12 faces the shell-laying device 2. A strip-shaped pallet 13 for aluminum extruded shells to be fitted is provided on the other side of the supporting vertical plates 12. A pressing mechanism 6 is provided on the outside of the strip-shaped pallet 13. The shell-laying device 2 is used to place the aluminum extruded shells to be assembled on the strip-shaped pallet 13. The pressing mechanism 6 is used to press the aluminum extruded shells. The swaying device 3 is used to place the explosion-proof plates to be assembled on the aluminum extruded shells.

[0052] The swaying device 3 includes a double-acting moving module 31, with one end of the double-acting moving module 31 positioned directly above the annular conveyor belt 1. Telescopic mechanisms 32 are provided on both moving ends of the double-acting moving module 31, and a mounting plate 33 is provided on the power output end of the telescopic mechanism 32. A material-collecting suction plate 34 is provided at the bottom of the mounting plate 33, and suction holes are provided at both ends of the bottom of the suction plate 34. The double-acting moving module 31 can drive the two telescopic mechanisms 32 to move, aligning either telescopic mechanism 32 with the explosion-proof sheet. The lifting height of the mounting plate 33 can be controlled by either telescopic mechanism 32, thereby bringing the mounting plate 33 close to the explosion-proof sheet for suction and material collection or swaying.

[0053] When picking up the explosion-proof sheet, the double-acting moving module 31 can drive one of the telescopic mechanisms 32 to move and align the explosion-proof sheet, and the telescopic mechanism 32 can drive the mounting plate 33 to move toward the top of the explosion-proof sheet to be assembled, so that the adsorption through hole comes into contact with the top of the explosion-proof sheet to be assembled for adsorption, and the mounting plate 33 can be driven to rise again by one of the telescopic mechanisms 32, thereby completing the explosion-proof sheet picking action.

[0054] To further explain the above structure, during the placement of the explosion-proof sheet, another telescopic mechanism 32 drives the mounting plate 33 to rise. At this time, the material-receiving suction plate 34 will attract the explosion-proof sheet and rise. The double-acting moving module 31 drives the other telescopic mechanism 32 to be directly above the circular conveyor belt 1. When the circular conveyor belt 1 places the mounting plate 11 with the aluminum extrusion shell directly below the telescopic mechanism 32, the conveying stops. The telescopic mechanism 32 drives the material-receiving suction plate 34 to approach the aluminum extrusion shell, so that the explosion-proof sheet at the bottom of the material-receiving suction plate 34 can contact the top of the aluminum extrusion shell until it is picked up. Then, the other telescopic mechanism 32 drives the material-receiving suction plate 34 to approach the safety opening of the aluminum extrusion shell again until the explosion-proof sheet is inside the safety opening of the aluminum extrusion shell. Then, the suction through hole of the material-receiving suction plate 34 cancels the suction state, the double-acting moving module 31 and the telescopic mechanism 32 reset, and the explosion-proof sheet placement action is completed. The circular conveyor belt 1 then conveys the mounting plate 11 again, so that the aluminum extrusion shell with the explosion-proof sheet can enter the subsequent work station.

[0055] It should also be noted that a correction mechanism 36 can be provided at the bottom of the swaying device 3. The correction mechanism 36 is located directly below the double-acting moving module 31. The correction mechanism 36 includes a pushing mechanism 361 and a receiving plate 362 for placing the explosion-proof plate. Limiting clamps 363 are provided at both ends of the outer side of the receiving plate 362, so that the two limiting clamps 363 are spaced apart and flush. Furthermore, movable clamps 364 are provided on both sides of the outer side of the receiving plate 362 to transmit the power of the pushing mechanism 361. The outlet end is fixedly connected to the movable clamping plate 364, and the range of motion of the movable clamping plate 364 can be controlled by the pushing mechanism 361. The opposite sides of the two movable clamping plates 364 are both set with an arc structure. The explosion-proof plate to be corrected is placed on the receiving plate 362 by the swing plate device 3. The limiting clamping plate 363 limits the two ends of the explosion-proof plate on the receiving plate 362. The two movable clamping plates 364 move towards the sides of the explosion-proof plate simultaneously until the two movable clamping plates 364 contact the explosion-proof plate, thereby correcting the position of the explosion-proof plate.

[0056] Specifically, a transport plane for conveying explosion-proof sheets can be provided at the bottom of the double-acting moving module 31. The double-acting moving module 31 can drive another telescopic mechanism 32, positioning it above the transport plane to pick up the explosion-proof sheets from the transport plane. The alignment and correction mechanism 36 is then moved again, and the other telescopic mechanism 32 moves the material suction plate 34 closer to the correction mechanism 36 until the explosion-proof sheet is on the receiving plate 362 and positioned between the two limiting clamps 363. The pushing mechanism 361 then moves the movable clamp 364 towards the two limiting clamps. The explosion-proof sheet moves between the limiting clamps 363 until the arc-shaped surface of the movable clamp 364 abuts against and pushes the explosion-proof sheet to perform a correction action until the correction action is completed. After the correction action is completed, the double-acting moving module 31 drives another telescopic mechanism 32 to take out the corrected explosion-proof sheet and place it into the safety opening of the aluminum extrusion shell, thus completing the explosion-proof sheet placement action. When the other telescopic mechanism 32 picks up the explosion-proof sheet on the transport plane and places it in the correction mechanism 36, the rotation direction of the explosion-proof sheet can also be adjusted by rotating the motor to ensure that the explosion-proof sheet is aligned with the correction station for placement.

[0057] Regarding the above structure, it should be further explained that, in order to achieve the position of the rotatable explosion-proof sheet after correction so that the explosion-proof sheet can be aligned with the safety opening of the aluminum extrusion shell, a rotary motor can be installed on the mounting plate 33 of another telescopic mechanism 32, and the material suction plate 34 of the other telescopic mechanism 32 can be movably installed at the bottom of the mounting plate 33. The material suction plate 34 is connected to the power output end of the rotary motor, and the rotation direction of the material suction plate 34 can be controlled by the rotary motor. This allows the placement position of the explosion-proof sheet to be rotatably adjusted when the other telescopic mechanism 32 takes out the explosion-proof sheet from the correction mechanism 36 and places it in the safety opening of the aluminum extrusion shell, and the placement is carried out from the conveying plane.

[0058] The dual-moving module 31 adopts a dual-moving structure. The explosion-proof sheet can be placed by the material suction plate 34 of one telescopic mechanism 32 and corrected by the correction mechanism 36. The material suction plate 34 of the other telescopic mechanism 32 can place the corrected explosion-proof sheet into the safety opening of the aluminum extrusion shell. In this embodiment, the two telescopic mechanisms 32 can operate synchronously, which improves work efficiency.

[0059] It should be noted that, in order to realize the feeding action of the explosion-proof discs, a feeding device 9 is also provided outside the disc-splitting device 3. The feeding device 9 includes a feeding turntable 91 and a rotating mechanism 92. The feeding turntable 91 is located at the other end near the double-acting moving module 31, and the rotating mechanism 92 is located at the bottom of the feeding turntable 91. The power output end of the rotating mechanism 92 is fixedly connected to the bottom center of the feeding turntable 91. Several disc-feeding mechanisms 93 are provided on the top of the feeding turntable 91. The disc-feeding mechanisms 93 are used to place the stacked explosion-proof disc groups. The disc-feeding mechanisms 93 are also used to feed the discs. The center distance of the material transfer plates 91 is the same. The rotating mechanism 92 drives the material transfer plate 91 to rotate, so that any one of the feeding mechanisms 93 on the material transfer plate 91 is aligned with the other end of the double-acting moving module 31. When the other end of the double-acting moving module 31 drives the telescopic mechanism 32 to align with the feeding mechanism 93, the power output end of the telescopic mechanism 32 can extend to bring the picking suction plate 34 close to the feeding mechanism 93 until the suction through hole of the picking suction plate 34 adsorbs the explosion-proof sheet in the feeding mechanism 93. After the adsorption is completed, the telescopic mechanism 32 drives the picking suction plate 34 to rise again to complete the picking action.

[0060] Example 5, in conjunction with the above examples, provides an automated production line for battery aluminum extrusion casings to be suitable for continuous production. This line includes the automated assembly equipment described in the previous examples, an aluminum casing feeding device 9, a casing feeding plane, and a discharge conveyor plane. The aluminum casing feeding device 9 is positioned near one end of the casing feeding plane, allowing it to place the casings to be extruded onto the feeding plane. The other end of the feeding plane is located directly below the casing removal device 7, enabling the sequential transport of the aluminum extrusion casings to be assembled to the casing removal device 7. The casing removal device 7 then removes the casings to be assembled. The assembled aluminum extruded shells are placed inside the shell-dispensing device 2 so that the shell-dispensing device 2 can smoothly place the aluminum extruded shells to be assembled onto the strip pallet 13; the material discharge conveying plane is located near the outside of the circular conveyor belt 1 and is also located directly below the material discharge device 5. Therefore, when the material discharge device 5 discharges the assembled battery shells from the circular conveyor belt 1 to the material discharge conveying plane, the assembled battery shells can be conveyed through the material discharge conveying plane, effectively allowing the strip pallet 13 on the material discharge conveying plane to be empty and flow back close to the shell-dispensing device 2, which is suitable for continuous production.
