[0002] With the nation's vigorous promotion of clean energy and strong call for environmental protection, the new energy vehicle industry has developed rapidly, leading to the booming lithium battery manufacturing industry in recent years. In the lithium-ion battery manufacturing system, metal connectors serve the dual functions of electrical connection and mechanical fixation between battery cells. Their manufacturing precision and reliability directly affect the conductivity, thermal management performance, and structural safety of the battery module. With the continuous improvement of battery energy density and system voltage platforms in new energy vehicles, and the development of integrated technologies such as CTP cell-to-pack and blade batteries, connectors are evolving towards ultra-thinness, large size, and multi-material composites, posing a serious challenge to traditional manufacturing processes.

[0003] The battery top cover connecting piece is an accessory for the top cover of new energy batteries. During processing, it requires stacking two pre-processed battery top cover connecting pieces, ultrasonic welding, post-weld leveling, cutting and positioning, and final cutting. Currently, each process is independently set up, with different transfer methods. This design uses four layers of pre-wound aluminum foil as a single workpiece. The two workpieces are then welded together and cut into the desired shape. All workstations are integrated into one machine, which is more integrated and consistent than traditional production. The cutting molds are automatically loaded and unloaded, making it safer than traditional production. Utility Model Content

The output ends of the other four forward extension cylinders are equipped with lifting cylinders, and the output ends of the lifting cylinders are equipped with suction plates. The lower end face of the suction plate is equipped with a suction nozzle. The grippers and four suction nozzles are respectively set to the feeding and stacking station, the connecting piece welding station, the post-weld leveling station, the cutting and positioning station, and the cutting station.

A rotary cylinder 205 is provided on the upper end face of the horizontal support platform 204. The rotary cylinder 205 drives the magazine fixing seat 206 to rotate. Two loading magazines 201 for stacking top cover connecting pieces are symmetrically arranged on both sides of the magazine fixing seat 206.

[0018] Among them, the transfer module assembly 3 includes a translation linear module 302. The output slider of the translation linear module 302 is provided with a lifting cylinder 301 along the vertical direction. The end of the lifting cylinder 301 is provided with a first suction plate 305. The lower end face of the first suction plate 305 is provided with a feeding nozzle 303 that simultaneously adsorbs or releases the two top cover connecting pieces in the receiving cavity. A translation stacking mechanism 304 is also provided between the stacking station 4 and the lifting cylinder 301. The translation stacking mechanism 304 includes a second suction plate 3044 that is driven to move in the vertical and horizontal directions by a second power structure. The lower end face of the second suction plate 3044 is provided with a stacking suction nozzle 3045 for adsorbing or releasing the top cover connecting piece. As a specific embodiment of this utility model, the second power structure can be configured as follows: The power structure includes a stacking lifting cylinder 3043 for switching the vertical position of the second suction plate 3044, the cylinder body of the stacking lifting cylinder 3043 is fixed to the output end of the stacking forward moving cylinder 3041 for switching the horizontal position of the second suction plate 3044, and the stacking forward moving cylinder 3041 is fixed to the transfer forward moving cylinder 3042 for extending or retracting the second suction plate 3044 to make way for the feeding nozzle 303; The stacking station 4 includes a positioning base plate 401. The upper end surface of the positioning base plate 401 is provided with a temporary storage cavity 402 for temporarily storing and accommodating the top cover connecting piece and a stacking cavity 403 for stacking and accommodating the top cover connecting piece.

[0019] As a preferred embodiment of this utility model: The outer side of the stacking cavity 403 has a notch 406 for grippers 507 to grasp the stacked top cover connecting pieces. The positioning base plate 401 is rotatably connected to the bracket 404 and the rotating shaft is rotatably connected to the power structure 405. The power structure 405 drives the positioning base plate 401 to reciprocate at a certain angle, so that the top cover connecting pieces grasped by the grippers 507 are disengaged from the stacking cavity 403.

[0020] Among them, the power structure 405 is a circumferential reciprocating power structure that provides power for the positioning base plate 401 to reciprocate at a preset angle.

[0021] As one embodiment of this utility model: the power structure 405 can be a geared motor, a pneumatic motor or a hydraulic motor.

[0022] Meanwhile, in another embodiment of this utility model: the positioning base plate 401 is rotatably connected to the bracket 404, and the rotating shaft is connected to the swing rod 407 by a key. The end of the swing rod 407 is provided with a sliding groove 408, and a connecting rod 409 is slidably arranged in the sliding groove 408. The connecting rod 409 is hinged to the slider 410. The power structure 405 is a linear output power structure 411. The output end of the linear output power structure 411, which moves in the horizontal direction, drives the slider 410 to move in the horizontal direction.

[0023] It should be noted that this utility model is an integrated production line system for battery top cover connecting pieces. In specific operation... 1. The gripper 507 holds the stacked battery top cover connecting piece. The power structure 405 drives the positioning base plate 401 to reciprocate at a certain angle, so that the top cover connecting piece held by the gripper 507 is separated from the stacking and receiving cavity 403. The forward cylinders 505 of the feeding and stacking station 2, the connecting piece welding station 6, the post-weld leveling station 7, the cutting and positioning station 8, and the cutting station 9 retract together and are separated from each station. 2. At this time, driven by the linear guide rail 511, the moving base plate 510 moves horizontally. Since five forward-extending cylinders 505 are equally spaced and correspond to the stacking station 4 (for loading and stacking), the connecting piece welding station 6, the post-weld leveling station 7, the cutting and positioning station 8, and the cutting station 9, respectively, at equal intervals... In this way, the stacked battery top cover connecting pieces are transferred to the connecting piece welding station 6 by the gripper 507. The forward extension cylinder 505 extends and places the stacked battery top cover connecting pieces into the welding groove of the connecting piece welding station 6, i.e., the ultrasonic welding machine body 601, through the gripper 507. The forward extension cylinder 505 retracts together, disengages from each station, and moves the base plate 510 horizontally to reset under the drive of the linear guide rail 511. Due to the long size of the workpiece, a two-stage welding method with a small welding head is adopted: after the workpiece is moved into place, the welding pressing cylinder 603 presses down to hold the workpiece, the ultrasonic welding machine body 601 works, welding 1 / 2 area, the welding lifting cylinder 605 rises, the welding translation cylinder 606 moves to the right, welding the remaining area, welding is completed, the welding translation cylinder 606 resets, welding is complete. 3. Similarly, the forward extension cylinder 505 extends, but the difference is that the output end of the forward extension cylinder 505 is equipped with a lifting cylinder 509, and the output end of the lifting cylinder 509 is equipped with a suction plate 508. The lower end face of the suction plate 508 is equipped with a suction nozzle. The welded battery top cover connecting piece is picked up by the suction nozzle. Driven by the linear guide rail 511, the moving base plate 510 moves horizontally. The welded battery top cover connecting piece is placed on the working surface of the post-weld leveling station 7. The pressing cylinder 701 pushes the shaping plate 709 to level the welded connecting piece. After leveling, the leveled connecting piece is transported to the cutting and positioning mechanism 8 for positioning by the connecting piece fork transport mechanism 5. 4. When the leveled connecting piece is transported to the positioning fixture 801, the long side positioning cylinder 805 and the short side positioning cylinder 807 extend to perform fine positioning of the connecting piece before cutting. After positioning is completed, the connecting piece is transported to the cutting mechanism 9 for cutting by the connecting piece fork transport mechanism 5. 5. When the connecting piece is transported to the cutting station 9, the hydraulic booster cylinder 901 works to cut the connecting piece to the required size through the upper cutting die 903 and the lower cutting die 904. After cutting, the cut finished product is transported to the material box by the connecting piece shift fork transport mechanism 5. The connecting plate shift fork conveying mechanism 5 is mainly driven by the linear module 514 to move the five sets of cylinders in the X direction. During the conveying process, the five stations move together, with the actions linked and the actions of each station in parallel, repeating the cycle.

[0024] As a supplement, the working principle of material loading and stacking is explained in further detail: 11. A rotary cylinder 205 drives the magazine holder 206 to rotate. Two loading magazines 201 for stacking top cover connecting pieces are symmetrically arranged on both sides of the magazine holder 206. Each loading magazine 201 has two top cover connecting piece receiving cavities 202, and multiple top cover connecting pieces are stacked in the top cover connecting piece receiving cavities 202. The end of the telescopic rod of the lifting module 203 is provided with a lifting block 207. The lifting block 207 can pass through the horizontal support platform 204 and the magazine fixing seat 206, and reciprocate in the vertical direction in the feeding magazine 201 to simultaneously lift the top cover connecting pieces in the two top cover connecting piece receiving cavities 202. This makes it convenient for the feeding nozzle 303 on the lower end face of the first suction plate 305 to simultaneously absorb or release the two top cover connecting pieces in the receiving cavity. 12. Driven by the translation linear module 302, the first suction plate 305, which adsorbs the two top cover connecting pieces, transfers the two top cover connecting pieces to the stacking station 4, and places the two top cover connecting pieces into the temporary storage cavity 402 and the stacking storage cavity 403 respectively. It needs to be explained at this point that, because subsequent processes include positioning, welding, and cutting, the inner diameter of the temporary storage cavity 402 and the stacking cavity 403 is generally slightly larger than the top cover connecting piece to facilitate insertion. 13. The vertical position of the second suction plate 3044 is adjusted by the stacking lifting cylinder 3043, and the horizontal position of the second suction plate 3044 is switched by the stacking forward moving cylinder 3041; while the second suction plate 3044 is extended or retracted by the transfer forward moving cylinder 3042 to make room for the feeding nozzle 303; in this way, the temporary storage cavity 402 can be transferred into the stacking cavity 403 through the stacking nozzle 3045. 14. As a preferred embodiment of this utility model, The power structure 405 drives the positioning base plate 401 to reciprocate at a certain angle, causing the top cover connecting piece held by the gripper 507 to disengage from the stacking cavity 403. This is mainly designed to cooperate with the linear guide rail in subsequent processes. The positioning, welding, and cutting processes in subsequent processes are all on the same linear guide rail side. Thus, in order for the gripper 507 to pick up and disengage the two stacked top cover connecting pieces in the stacking cavity 403, it is necessary to raise and lower the gripper 507 and extend and retract it in the horizontal direction. The power structure 405 drives the positioning base plate 401 to reciprocate at a certain angle. In this way, the gripper 507 in the notch 406 picks up the two top cover connecting pieces. As the positioning base plate 401 rotates, the top cover connecting pieces are disengaged from the side wall of the stacking and receiving cavity 403 at the notch 406. They can be transferred to the subsequent process by using the linear guide rail with only horizontal extension and retraction.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
