[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] refer to Figures 1 to 4 The reverse adhesive application device provided in this embodiment includes a conveying mechanism 1, and a cell positioning mechanism 2 and an adhesive application mechanism 3 arranged sequentially along the conveying direction of the conveying mechanism 1. The adhesive application mechanism 3 includes an adhesive paper supply unit 31 and an adhesive application unit 32 located on one side of the conveying mechanism 1. The adhesive application unit 32 operates between the adhesive paper supply unit 31 and the conveying mechanism 1 and is used to attach adhesive paper to the lower surface of the cell. The cell positioning mechanism 2 can be a visual positioning mechanism or a mechanical positioning mechanism. In this embodiment, the cell positioning mechanism 2 is a visual positioning mechanism. The cell positioning mechanism 2 can obtain the position information of the cell located on the conveying mechanism 1 and send it to the adhesive application unit 32.

[0039] A first adhesive tape positioning unit 33 is provided below the adhesive tape supply unit 31, and a second adhesive tape positioning unit 34 is provided between the adhesive tape supply unit 31 and the conveying mechanism 1, with the second adhesive tape positioning unit 34 located on the working path of the adhesive application unit 32. The first adhesive tape positioning unit 33 is used to obtain the position information of the adhesive tape to be picked up on the adhesive tape supply unit 31 and send it to the adhesive application unit 32, so that the adhesive application unit 32 can accurately pick up the adhesive tape from the adhesive tape supply unit 31; the second adhesive tape positioning unit 34 is used to obtain the position information of the adhesive tape to be applied on the adhesive application unit 32 and send it to the adhesive application unit 32, so that the adhesive application unit 32 can accurately apply the adhesive tape to the target application position on the lower surface of the battery cell.

[0040] In some embodiments, the cell positioning mechanism 2 includes a first positioning CCD 21, which is disposed below the conveying mechanism 1. When the conveying mechanism 1 conveys the cell to the position of the first positioning CCD 21, the first positioning CCD 21 faces upward to photograph the head area of ​​the cell, thereby obtaining the cell's position information and sending it to the adhesive application unit 32. The first adhesive tape positioning unit 33 includes a second positioning CCD 331, which is disposed below the adhesive tape supply unit 31. When the adhesive application unit 32 is ready to pick up the adhesive tape, the second positioning CCD 331 faces upward to photograph the adhesive tape to be picked up on the adhesive tape supply unit 31, thereby obtaining the position information of the adhesive tape to be picked up and sending it to the adhesive application unit 32. The second adhesive tape positioning unit 34 includes a third positioning CCD 341, which is located between the adhesive tape supply unit 31 and the conveying mechanism 1. When the adhesive application unit 32 passes the position of the third positioning CCD 341, the third positioning CCD 341 takes a picture of the adhesive tape to be applied on the adhesive application unit 32 from below, thereby obtaining the position information of the adhesive tape to be applied and sending it to the adhesive application unit 32.

[0041] In some implementations, supplementary light sources can be provided above the first positioning CCD 21 and above the second positioning CCD 331, and supplementary light sources can also be provided below the third positioning CCD 341. The first positioning CCD 21, the second positioning CCD 331 and the third positioning CCD 341 can all be configured to be position-adjustable to adapt to different production operation needs.

[0042] The reverse adhesive application equipment in this embodiment accurately positions the battery cell using a cell positioning mechanism. A first adhesive positioning unit accurately acquires the position information of the adhesive paper to be picked up from the adhesive paper supply unit and sends it to the adhesive application unit. A second adhesive positioning unit accurately acquires the position information of the adhesive paper to be applied from the adhesive application unit and sends it to the adhesive application unit as well. This allows the adhesive application unit to accurately apply the adhesive paper to the target application position on the lower surface of the battery cell, effectively improving the accuracy of the reverse adhesive application operation and thus enhancing the production quality of the battery cell.

[0043] Example 2

[0044] As a further optimization of Example 1, refer to Figures 5 to 8 The adhesive application unit 32 includes a first adsorption component 321, a second adsorption component 322, and a first driving component 323. Both the first adsorption component 321 and the second adsorption component 322 are connected to the driving end of the first driving component 323, which can be a robotic arm. In this embodiment, the first adsorption component 321 and the second adsorption component 322 have identical structures. They are used to apply adhesive tape to two adjacent battery cells on the conveying mechanism 1. The first adsorption component 321 and the second adsorption component 322 can simultaneously acquire adhesive tape from the adhesive tape supply unit 31 and together perform adhesive tape positioning via the second adhesive tape positioning unit 34. Then, the first adsorption component 321 and the second adsorption component 322 successively apply the acquired adhesive tape to two adjacent battery cells on the conveying mechanism 1. This shortens the travel path of the adhesive application unit 32, improves the efficiency of the adhesive application operation, and also reduces equipment energy consumption and controls production costs.

[0045] The first adsorption component 321 includes a suction block 3211. A buffer spring 3212 is vertically arranged between the suction block 3211 and the driving end of the first driving component 323. The top of the suction block 3211 is provided with several suction holes 3213. By setting the buffer spring 3212, a buffering effect can be provided during the adhesive tape application process, avoiding excessive pressure of the suction block 3211 on the lower surface of the battery cell, which could lead to damage to the battery cell.

[0046] As a further optimization, the adhesive application mechanism 3 also includes a battery cell fixing unit 35 disposed above the conveying mechanism 1. The battery cell fixing unit 35 includes a fixing block 351 and a second drive assembly 352 for driving the fixing block 351 to move vertically. The second drive assembly 352 can be a drive cylinder. The fixing block 351 is used to abut against the head of the battery cell. Since the adhesive application unit 32 moves from bottom to top to attach the adhesive to the area near the head of the battery cell on the lower surface of the battery cell during the adhesive application operation, the fixing block 351 moves from top to bottom to abut against the head of the battery cell, which can limit and fix the battery cell during the adhesive application process, thereby ensuring the stability of the adhesive application process.

[0047] Example 3

[0048] As a further optimization of Example 1, refer to Figures 9 to 12The adhesive tape supply unit 31 includes a feeding roller 311, a receiving roller 312, an adhesive stripper 313, and a third drive assembly 314 for driving the adhesive stripper 313 to move horizontally. The third drive assembly 314 can be a drive motor. The adhesive stripper 313 is disposed below the feeding roller 311 and the receiving roller 312, and the first adhesive tape positioning unit 33 is disposed below the adhesive stripper 313. In some embodiments, a plurality of feeding guide rollers 315 are further disposed between the feeding roller 311 and the adhesive stripper 313, and a plurality of receiving guide rollers 316 are further disposed between the receiving roller 312 and the adhesive stripper 313.

[0049] Understandably, the adhesive tape sequentially passes over the feeding roller 311, the feeding guide roller 315, the adhesive stripper 313, the take-up guide roller 316, and the take-up roller 312. Initially, the adhesive stripper 313 is extended. When the adhesive application unit 32 picks up the adhesive tape from below the adhesive stripper 313, the adhesive stripper 313 will retract under the drive of the third drive component 314, causing the adhesive tape picked up by the adhesive application unit 32 to separate from the adhesive tape, thereby ensuring that the adhesive application unit 32 can smoothly pick up the adhesive tape.

[0050] In some embodiments, the adhesive application mechanism 3 further includes a spare adhesive tape supply unit 36, which is arranged adjacent to the adhesive tape supply unit 31. The adhesive application unit 32 operates between the adhesive tape supply unit 31 and the conveying mechanism 1, or between the spare adhesive tape supply unit 36 ​​and the conveying mechanism 1. The structure of the spare adhesive tape supply unit 36 ​​is the same as that of the adhesive tape supply unit 31. When the adhesive tape on the adhesive tape supply unit 31 is exhausted, the adhesive application unit 32 can directly pick up adhesive tape from the spare adhesive tape supply unit 36 ​​without waiting for the adhesive tape supply unit 31 to refill, thereby ensuring the continuity of the adhesive application operation and improving the efficiency of the adhesive application operation.

[0051] In one embodiment, the conveying mechanism 1 includes a drive unit 11, a moving guide rail 12, and multiple positioning seats 13. The positioning seats 13 are slidably connected to the moving guide rail 12. The drive unit 11 is used to drive the positioning seats 13 to move horizontally along the moving guide rail 12. The drive unit 11 can be a drive motor. In this embodiment, the conveying mechanism 1 is used to convey battery cell assemblies. Each positioning seat 13 is used to support and fix one battery cell assembly. The battery cell assembly includes a clamp 100 and a battery cell 200. The main body of the battery cell 200 is clamped in the clamp 100, and the head of the battery cell 200 is exposed outside the clamp 100, which can be used by the battery cell positioning mechanism 2 for positioning and by the adhesive applicator 3 for adhesive applicator operation.

[0052] In this embodiment, there are two cell positioning mechanisms 2 and two adhesive application mechanisms 3, with the two cell positioning mechanisms 2 arranged adjacent to each other and the two adhesive application mechanisms 3 arranged adjacent to each other. This allows for the application of adhesive to four cells in each adhesive application cycle, effectively improving the efficiency of the adhesive application process.
