[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 - Figure 9 As shown, the fully automatic assembly machine for soft-pack battery cell clamps provided in this embodiment includes: a feeding assembly 200; a conveying component 300, which includes a first conveying component and a second conveying component, the second conveying component being used to feed the battery cells, and the first conveying component being used to transfer the clamps, foam, and the battery cells conveyed by the second conveying component; a dust removal station 400, used to remove dust from the surface of the clamps conveyed by the conveying component 300; a flipping station 500, used to flip the clamps after dust removal; and a processing station 600, used to fix the placed clamps, foam, and battery cells.

[0030] In this embodiment, when the first conveying component conveys the clamping plate, it first moves the clamping plate to the dust removal station 400, where the dust removal station 400 cleans the dust adhering to the surface of the clamping plate. Then, the clamping plate is conveyed to the flipping station 500, where the direction of the clamping plate is reversed. The first conveying component then picks up and fixes the clamping plate again, and then cleans the other side of the clamping plate. The cleaned clamping plate is placed at the processing station 600, where the first conveying component then conveys the foam to the upper surface of the clamping plate at the processing station 600. The second conveying component conveys the battery cell to the upper surface of the foam at the processing station 600. The first conveying component then conveys the foam and the clamping plate in sequence. The processing station 600 assembles the placed battery cell, foam, and clamping plate, and the first conveying component conveys the assembled finished product to the designated position.

[0031] The feeding assembly 200 includes a cell trolley 201 for conveying the cells, a clamping plate trolley 202 for conveying the clamping plates, a foam hopper 203 for placing the foam, and a finished product trolley 204 for unloading and transporting the assembled soft-pack cells.

[0032] It also includes: a housing 100, a conveying component 300, a dust removal station 400, a tilting station 500, a processing station 600, and a foam material hopper 203, all of which are set on the housing 100.

The second part and the third part are respectively disposed on two side walls of the battery cell box. The first part is disposed at the bottom of the inner wall of the battery cell box. Multiple grooves are provided at equal intervals in both the second part and the third part. The upper surface of the first part has grooves corresponding to the grooves.

[0035] like Figure 8As shown, the clamping plate cart 202 includes a handcart body and a placement plate disposed on the top of the handcart body. The placement plate is provided with two sets of placement components for placing clamping plates. The placement components include two U-shaped baffles. The baffles are slidably connected to the placement plate. The clamping plates are placed between the two baffles. The baffles and the placement plate are locked together by bolts.

[0036] like Figure 9 As shown, the finished product cart 204 includes a handcart body and a finished product frame set on top of the handcart body. Three sets of limiting members are set in the finished product frame for placing finished products. The limiting members are used to separate each finished product and prevent collisions between adjacent finished products during transportation.

[0037] like Figure 5 As shown, the first conveying component includes a vacuum suction cup 301, a first driving member 302, and a first vertical driving member 303. The first driving member 302 is disposed above the housing 100 and is used to drive the first vertical driving member 303 to move laterally or longitudinally. The first vertical driving member 303 is used to drive the vacuum suction cup 301 to move.

[0039] like Figure 6 As shown, the second conveying component includes a second driving member 305, a second suction cup 306, a second vertical driving member 307, and a belt conveyor 309. The second driving member 305 is used to drive the second vertical driving member 307 to move longitudinally, and the second vertical driving member 307 is used to drive the second suction cup 306 to move up and down. A second actuator 308 is provided between the second suction cup 306 and the second vertical driving member 307 to flip the second suction cup 306. The belt conveyor 309 is used to position and convey the battery cell conveyed by the second suction cup 306.

[0040] In this embodiment, the second driving component 305 includes a slide rail and a movable seat slidably connected to the slide rail. A motor and a threaded screw are mounted on the slide rail for longitudinal driving of the movable seat. The movable seat is equipped with a mounting box and a housing that can slide up and down on the mounting box. A motor and a threaded screw are mounted on the mounting box for vertical driving of the housing. A second actuator 308 is disposed inside the housing. The output shaft of the second actuator 308 extends out of the left side of the housing and is fixedly mounted with a connecting plate. The end of the connecting plate is connected to a second suction cup 306. During the feeding of the battery cell, the motor and threaded screw... Under the action of the vacuum pump, the second suction cup 306 is moved to one side of the battery cell. The vacuum pump starts working so that the second suction cup 306 can adsorb and fix the battery cell. Then the motor starts working again to move the battery cell to the belt conveyor 309. The second actuator 308 works to make the battery cell horizontal and directly above the belt conveyor 309. The belt conveyor 309 transports the battery cell to the designated position. Then the first conveying component transports the battery cell to the upper surface of the foam at the processing station 600. The belt conveyor 309 is equipped with a cylinder and a push plate to adjust the position of the battery cell on the belt conveyor 309.

[0041] like Figure 3 As shown, the flipping station 500 includes a support frame 501. An upper suction cup 502 is slidably connected to the top of the support frame 501. An actuator 503 for driving the upper suction cup 502 to flip is provided on one side of the support frame 501. A lower suction cup 507 is provided below the upper suction cup 502. A plate 504 is provided below the lower suction cup 507. A cylinder 505 for driving the lower suction cup 507 to move upward is provided on the plate 504. An actuator 506 for driving the plate 504 to generate displacement is provided below the plate 504.

[0042] The dust removal station 400 includes a dust collection seat 401. A through groove 402 corresponding to the clamping plate is provided on the upper side of the dust collection seat 401. A vacuum cleaner is provided below the dust collection seat 401. The through groove 402 is connected to the air intake pipe of the vacuum cleaner.

[0043] In this embodiment, when cleaning the surface of the clamping plate, the conveying member 300 brings one side of the lower surface of the clamping plate against the upper surface of the dust collection seat 401, and then moves the clamping plate laterally. The vacuum cleaner starts working. When the clamping plate aligns with the through groove 402, the dust adhering to the surface of the clamping plate is cleaned under the action of suction. After cleaning, the clamping plate is placed on the lower suction cup 507. The actuator 2 506 starts working, causing the plate 504 to move the lower suction cup 507 until the clamping plate is directly below the upper suction cup 502. Then, the actuator 1 503 starts working. The upper suction cup 502 is flipped over, and then cylinder 2 505 starts working to push the clamping plate up to fit with the upper suction cup 502. Then the upper suction cup 502 adsorbs the clamping plate. The vacuum blows air onto the lower suction cup 507 to separate the clamping plate from the lower suction cup 507. Cylinder 2 505 drives the lower suction cup 507 to reset. Actuator 1 503 works to reset the upper suction cup 502. The conveying component 300 adsorbs and fixes the flipped clamping plate. Then, with the cooperation of the dust removal station 400, the other side is cleaned. After the dust removal is completed, the clamping plate is conveyed to the processing station 600.

[0046] In this embodiment, the conveying component 300 places the cleaned clamping plate onto the base plate 6043, and then sequentially places the foam, battery cell, foam, and clamping plate. After placement, the actuator 3 6044 drives the U-shaped plate 6042 to move until the base plate 6043 is directly below the U-shaped frame 6041. The actuator 3 6044 then pushes the base plate 6043 upward, and with the cooperation of the U-shaped frame 6041, the clamping work of the battery cell, foam, and clamping plate is completed. The feeding part conveys the required screws to the electric screwdriver part at the end of the robot arm 601. The end of the robot arm 601 moves the electric screwdriver part to the designated position to fix the battery cell, foam, and clamping plate. After assembly, the conveying component 300 conveys the finished product. Under the action of the printer 603, relevant information is printed on the surface of the finished product. Then, the conveying component 300 places the finished product into the finished product cart 204.
