[0033] The double-sided adhesive layer of lithium battery double-sided tape is usually a continuous composite layered structure. This composite layered structure is composed of two adhesive layers and a thin film substrate, which are laminated in the order of adhesive layer-thin film substrate-adhesive layer. In the process of applying double-sided tape containing the thin film substrate, the substrate needs to be bonded to the battery cell first, then the substrate is rolled, and finally the release paper is peeled off from the adhesive layer.

[0034] When peeling the release substrate from the double-sided adhesive layer, you need to first insert the pin between the adhesive layer and the release paper, and then peel the release paper off the adhesive layer. Because the adhesive layer and the release paper are relatively thin, the pin is prone to colliding with the battery cell during the insertion process, which may eventually lead to the battery cell being punctured.

[0035] Based on this, the embodiments of this specification propose a cell roll-pressing and tearing mechanism: such as Figure 1 As shown, a battery cell roll-pressing and tearing mechanism includes a robotic arm (not shown in the figure), a telescopic clamping pin 4, and a telescopic detection sensor 8 (see figure 8). Figure 3 The robotic arm is connected to a support frame 1, and the support frame 1 is connected to two lifting and fixing blocks 2, which are respectively located at both ends of the support frame 1.

[0036] like Figure 2 and Figure 3 As shown, the lifting and fixing block 2 is connected to a clamping and lifting cylinder 3, which in turn is connected to a clamping block 5, which is rectangular in shape. The lifting and fixing block 2 is connected to a telescopic fixing plate 6, which is connected to an elastic element 7. The elastic element 7 abuts against and fixes the telescopic clamping pin 4. The telescopic clamping pin 4 is slidably connected to the telescopic fixing plate 6 and the elastic element 7. The clamping block 5 is located directly above the telescopic clamping pin 4. When the telescopic clamping pin 4 is not in contact with the battery cell, the elastic element 7 abuts against and fixes the telescopic clamping pin 4, allowing it to be inserted between the release paper and the adhesive layer. When the telescopic clamping pin 4 contacts the battery cell, due to the excessive force on it, the telescopic clamping pin 4 contracts, causing the elastic element 7 to deform. The telescopic detection sensor 8 detects whether the telescopic clamping pin 4 has moved.

[0037] like Figure 2 and Figure 3 As shown, the robotic arm moves the telescopic clamping pin 4 via the support frame 1 and the lifting fixing block 2, inserting the telescopic clamping pin 4 between the release paper and the adhesive layer. The clamping lifting cylinder 3 moves the clamping block 5 toward the telescopic clamping pin 4, and the clamping block 5 and the telescopic clamping pin 4 clamp the release paper. The robotic arm moves the clamping block 5 and the telescopic clamping pin 4 to separate the release paper from the adhesive layer. When the telescopic clamping pin 4 comes into contact with the battery cell, the telescopic clamping pin 4 moves under force. The telescopic detection sensor 8 detects the movement of the telescopic clamping pin 4, and the robotic arm stops moving, thus avoiding the occurrence of battery cell puncture.

[0038] In this embodiment, the elastic element 7 is a spring, which is sleeved on the telescopic clamping pin 4. One end of the spring is connected to the telescopic clamping pin 4, and the other end of the spring is connected to the telescopic fixing plate 6. The telescopic fixing plate 6 has a through hole, and the spring is disposed in the through hole of the telescopic fixing plate 6. The telescopic clamping pin 4 can slide in the through hole.

[0039] The spring abuts and fixes the telescopic clamping pin 4. Under the elastic resistance of the spring, the telescopic clamping pin 4 is precisely inserted between the adhesive layer and the release paper. When it encounters the battery cell, the telescopic clamping pin 4 retracts and the spring deforms.

[0040] In this embodiment, a locking nut 9 is connected to the end of the telescopic clamping pin 4 that is away from the release paper. The locking nut 9 can abut against the telescopic fixing plate 6. The locking nut 9 limits the length of the telescopic clamping pin 4.

[0041] In this embodiment, the telescopic detection sensor 8 is mounted on the telescopic fixing plate 6, and a sensor detection block 10 is located near the locking nut 9 on the telescopic clamping pin 4. The telescopic detection sensor 8 is used to detect whether the sensor detection block 10 has shifted. The telescopic detection sensor 8 is electrically connected to the robotic arm. When the telescopic clamping pin 4 contacts the battery cell, the telescopic detection sensor 8 detects that the sensor detection block 10 has shifted, and the robotic arm stops moving to prevent the battery cell from being punctured.

[0042] like Figure 4 As shown, the cell rolling and tearing mechanism also includes a rolling component, which includes a roller lifting cylinder 11. The roller lifting cylinder 11 is connected to the support frame 1 via a lifting fixing block 2 (see...). Figure 1 The roller lifting cylinder 11 is connected to the roller pressure roller 13 via the roller fixing frame 12. When it is in a non-rolling state, the roller pressure roller 13 is located on the side away from the release paper of the telescopic clamping pin 4.

[0043] like Figure 3 and Figure 4 As shown, when the release paper needs to be torn off, the clamping block 5 and the telescopic clamping pin 4 tear off the release paper under the action of the robot. When the release paper needs to be rolled, the roller lifting cylinder 11 drives the roller 13 to move to the surface of the release paper, and the robot drives the roller 13 to roll the release paper.

[0044] In this embodiment, the lifting fixing block 2 is connected to the lifting guide rail slider 14, and the roller fixing frame 12 is connected to the lifting guide rail slider 14. This improves the stability during roller movement.

[0045] like Figure 5 , Figure 6 and Figure 7 As shown, the roller lifting cylinder 11 is connected to an adjusting bracket 15, and the adjusting bracket 15 is connected to the lifting guide rail slider 14 (see...). Figure 4 The sliding connection is provided, and the adjusting bracket 15 has a groove. The roller fixing frame 12 is connected to the connecting block 16, which is rotatably connected to the adjusting bracket 15. There is a gap between the connecting block 16 and the inner wall of the groove. When there is an angle on the plane where the release paper is located, the roller 13 can automatically adjust to avoid unbalanced force on the battery cell roller.

[0046] In this embodiment, the connecting block 16 is rotatably connected to the lifting guide rail slider 14 via the adjusting pin 17. The adjusting pin 17 is located in the middle position of the connecting block 16, and the connecting block 16 can rotate 0-2° around the adjusting pin 17.

[0047] The lifting fixed block 2 is connected to a position detection sensor 18, and the roller lifting cylinder 11 is connected to a position detection block 20. The position detection sensor 18 is fixed to the lifting fixed block 2 via a sensor bracket 19. The position detection sensor 18 detects the movement position of the roller lifting cylinder 11 and determines whether the roller lifting cylinder 11 has retracted into its position, completing one cycle.

[0048] The robotic arm moves the telescopic clamping pin 4 via the support frame 1 and the lifting fixing block 2, inserting the telescopic clamping pin 4 between the release paper and the adhesive layer. The clamping lifting cylinder 3 moves the clamping block 5 toward the telescopic clamping pin 4, and the clamping block 5 and the telescopic clamping pin 4 clamp the release paper. The robotic arm moves the clamping block 5 and the telescopic clamping pin 4 to separate the release paper from the adhesive layer. When the telescopic clamping pin 4 comes into contact with the battery cell, the telescopic clamping pin 4 moves under force. The telescopic detection sensor 8 detects the movement of the telescopic clamping pin 4, and the robotic arm stops moving, thus avoiding the occurrence of battery cell puncture.

[0049] When the release paper needs to be torn off, the clamping block 5 and the telescopic clamping pin 4, driven by the robotic arm, tear off the release paper. When the release paper needs to be rolled, the roller lifting cylinder 11 moves the roller 13 to the surface of the release paper, and the robotic arm drives the roller 13 to roll the release paper. When there is an angle on the plane where the release paper is located, the roller 13 can automatically adjust to avoid unbalanced force on the battery cell rollers.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
