[0002] In battery production, one of the processes is wrapping with blue film. The purpose of wrapping with blue film is to cover the entire soft-pack battery cell, making it a whole unit with an outer layer. This is to better protect the cell during transportation and distribution, achieving dustproof and waterproof effects, and also preparing for subsequent hot-pressing encapsulation.

The two transfer grippers 253 transfer the battery cell, which is horizontal between the two gripping grippers 214, to the first conveying station 32 or the second conveying station 33. The lifting component 255 can be a motor-driven screw-nut assembly, which is a common structure in the mechanical field. Its specific structure and working principle will not be further described here.

[0039] The second transfer assembly 26 has a structure that is basically the same as that of the first transfer assembly 25. The difference is that it also includes a rotating cylinder 261 mounted on the lifting seat 252 and a rotating frame 262 mounted at the front end of the rotating cylinder 261 and connected to the transfer cylinder 254. The rotating cylinder 261 and the rotating frame 262 are provided on the second transfer assembly 26 to rotate the battery cell held on the second transfer assembly 26 by 180°, so that the positive and negative terminals of the battery cell on the second conveying station 33 can be arranged in the same direction as the positive and negative terminals of the battery cell on the first conveying station 32, so as to prevent the subsequent coating process from coating the positive and negative terminals of the battery cell.

The transfer gripper 253 clamps and transfers the battery cell onto the first conveying seat 321. The first moving cylinder 325 drives the first moving plate 323 to move closer to the first fixed conveying wheels 322, so that the battery cell is positioned between the plurality of first fixed conveying wheels 322 and the plurality of first moving conveying wheels 324.

Specifically, the first guide wheel group 3261 includes a plurality of guide wheels located below the first fixed conveying wheel 322 or the first moving conveying wheel 324. The axis of the guide wheel is arranged perpendicular to the axis of the first fixed conveying wheel 322 or the first moving conveying wheel 324.

[0043] The conveying device 3 further includes a first feeding mechanism 36 disposed on the frame 1 opposite to the first feeding position 311 and a second feeding mechanism 37 disposed on the frame 1 opposite to the second feeding position 312. The first feeding mechanism 36 pushes the battery cells supported on the first conveying seat 321 into the conveying channel 3264. It includes a first feeding frame 361 disposed on the frame 1 opposite to the first feeding position 311, a first feeding cylinder 362 disposed on the first feeding frame 361, and a first feeding plate 363 disposed at the front end of the first feeding cylinder 362 to push the battery cells to move. Specifically, the second feeding mechanism 37 is opposite to the second feeding position 312, and pushes the battery cells on the second conveying station 33 to the side close to the coating device 4. Furthermore, the structure of the second conveying station 33 is the same as that of the first conveying station 32, and its specific structure will not be described in detail here.

The drive mechanism 49 connects to and drives the film-pulling roller 45 to move up and down. When the film-pulling roller 45 is at its highest position, its roller surface is bonded to the adhesive surface of the coating film. When the film-pulling roller is at its lowest position, the end of the coating film descends to prepare for the coating of the battery cell. The forward and backward moving mechanism 48 can drive the film-pulling roller 45 to move outward, facilitating its up and down movement. When the film-pulling roller is at its lowest or highest position, the forward and backward moving mechanism 48 drives the film-pulling roller 45 to retract inward to ensure the coating quality of the battery cell. Specifically, the forward and backward moving mechanism 48 can be a cylinder to realize the forward and backward movement of the film-pulling roller 45 relative to the coating frame 41. The lateral moving mechanism 47 can be a rodless cylinder. The drive mechanism 49 can be a combination of a motor, gear belt, and connecting block. The above methods are common in the mechanical field, and their specific structures and working principles will not be further elaborated here.

[0047] The coating mechanism 43 includes an upper coating roller shaft 431 and a lower coating roller shaft 432 arranged opposite each other on the coating frame 41, a first lifting mechanism 433 connected to and driving the upper coating roller shaft 431 to move up and down on the coating frame 41, and a second lifting mechanism 434 connected to and driving the lower coating roller shaft 432 on the coating frame 41. A coating area 435 opposite to the coating position 313 is formed between the upper coating roller shaft 431 and the lower coating roller shaft 432. Specifically, the first lifting mechanism 433 and the second lifting mechanism 434 can be cylinders.

[0048] The film feeding mechanism 44 includes a film feeding frame 441 located behind the film wrapping frame 41 on the frame 1 and multiple guide rollers 442 alternately arranged on the film feeding frame 441 to guide the movement of the film wrapping film. The film wrapping film is guided by the multiple guide rollers 442 to be bonded to the film pulling roller 45.

[0049] The method for coating the large surface area of ​​a battery cell using the aforementioned device specifically includes the following steps:

[0050] Step 1: The battery cell is conveyed vertically to the clamping mechanism 21. The two clamping grippers 214 clamp the battery cell and, under the action of the flipping component 216, flip it upward by 90°, so that the battery cell is in a horizontal state.

[0051] Step 2: The first transfer component 25 clamps the battery cell held by the two clamping grippers 214, and rotates 90° to the left under the action of the rotating component 27 until it is opposite to the first loading position 311. At this time, the second transfer component 26 rotates to be opposite to the clamping mechanism 21 and clamps the battery cell. Then, the lifting component 255 drives the two transfer grippers 253 to move downward to place the battery cell on the first conveying seat 321 and move upward to reset. At this time, the rotating frame 24 can rotate 90° to the right so that the second transfer component 26 clamps the battery cell to be opposite to the second loading position 312.

[0052] Step 3: The first moving cylinder 325 drives multiple first conveying fixed rollers 322 to move closer to multiple first conveying moving rollers 324, so that the battery cell is positioned between the multiple first conveying fixed rollers 322 and the multiple first conveying moving rollers 324. Then the first feeder 36 pushes the battery cell forward into the conveying channel 3264.

[0053] Step 4: The moving mechanism 34 drives the first conveying station 32 to move to the right to the wrapping position 313. At this time, the second conveying station 33 moves to the second feeding position 312 to receive the battery cell transferred by the second transfer component 26.

[0054] Step 5: The film-pulling roller 45 moves downward, causing the coating film to move downward to the lowest position. The upper coating roller shaft 431 and the lower coating roller shaft 432 make the coating area 435 opposite to the battery cell in the coating position 313. Then, the film-pulling roller 45 moves upward until it abuts against the lower coating roller shaft 432. The pusher drive 354 drives the pusher frame 352 to move closer to the conveyor frame 31, so that the pusher plate 353 pushes the battery cell in the conveyor channel 3264 to the coating area 435 and supports it on the support frame 42. During the movement of the battery cell, the coating film will complete the coating of the large surface of the battery cell. Then, the lateral movement mechanism 47 drives the cutter 46 to move and cut the coating film.

[0055] Step 6: After the coating film is cut, the film pulling roller 45 moves upward to the highest position and adheres to the adhesive surface at the lower end of the coating film. The upper coating roller shaft 431 and the lower coating roller shaft 432 move upward to reset, preparing for the next cell coating.

[0056] This application defines the specific structure of the equipment, which, through the cooperation of the feeding device 2, the conveying device 3, and the coating device 4, achieves automatic feeding and coating of battery cells. The conveying device 3 is provided with a first conveying station 32 and a second conveying station 33. The conveyor frame 31 is provided with a first feeding position 311, a second feeding position 3123, and a coating position 13 at intervals. When the first conveying station 32 moves to the coating position 313, the second conveying station 33 moves to the second feeding position 311; when the second conveying station 33 moves to the coating position 313, the first conveying station 32 moves to the first feeding position 311. This achieves dual-channel switching of the conveying mode to improve the production efficiency of battery cell coating.

[0057] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
