[0036] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0037] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0038] Embodiment 1

[0039] Refer to Figures 1 to 7 , the pasting mechanism provided in this embodiment includes a driving module 1 and a glue-folding and pasting module 2 that is drivingly connected to the driving module 1. In some embodiments, the driving module 1 is a robotic arm for driving the glue-folding and pasting module 2 to move between the glue paper supply mechanism and the battery cell to be pasted, and complete the actions of taking glue and pasting glue.

[0040] The glue-folding and pasting module 2 includes a fixed limit unit 21 for fixing the body part of the glue paper and a glue paper bending unit 22 for bending the part of the glue paper to be bent. The first crease positioning part 211 and the second crease positioning part 212 are arranged in a staggered manner on the fixed limit unit 21, and the glue paper bending unit 22 is used to move the part of the glue paper to be bent along the first crease positioning part 211 and the second crease positioning part 212 for bending.

[0041] As Figure 3As shown, the adhesive tape A includes a body part A1 and a bent part A2 connected to the body part A1. The bent part A2 includes a first bent part A21 and a second bent part A22. The first bent part A21 and the second bent part A22 are independent of each other and are juxtaposed. It can be understood that when the tape folding and pasting module 2 picks up the tape, the body part A1 is fixed on the fixed limit unit 21. The first bent part A21 exactly corresponds to the position of the first crease positioning part 211, and the second bent part A22 exactly corresponds to the position of the second crease positioning part 212. The tape bending unit 22 can drive the first bent part A21 and the second bent part A22 to be bent along the first crease positioning part 211 and the second crease positioning part 212 respectively.

[0042] In some embodiments, the fixed limit unit 21 and the tape bending unit 22 can be located on the same side of the tape. The bent part A2 is fixed on the tape bending unit 22 and can move with the movement of the tape bending unit 22, so as to realize the bending of the bent part A2. In other embodiments, the fixed limit unit 21 and the tape bending unit 22 are respectively located on two opposite sides of the tape. The bent part A2 is not fixed by the tape bending unit 22, and the movement of the tape bending unit 22 is used to push the bent part A2 to move, so as to realize the bending of the bent part A2.

[0043] It can be understood that the first crease positioning part 211 and the second crease positioning part 212 are adjacent in position and there is a height difference between them. The height difference between the first crease positioning part 211 and the second crease positioning part 212 coincides with the height difference of the head of the cell to be pasted with tape. By bending the first bent part A21 and the second bent part A22 along the first crease positioning part 211 and the second crease positioning part 212 respectively through the tape bending unit 22, the shape of the bent tape can coincide with the shape of the head of the cell to be pasted with tape, so as to realize complete adhesion, with high adhesion and ensure the production quality of the cell product.

[0044] In some embodiments, the adhesive tape bending unit 22 includes a first bending assembly 221, a second bending assembly 222, and a rotation driving assembly 223 for driving the first bending assembly 221 and the second bending assembly 222 to rotate synchronously. The fixed end of the rotation driving assembly 223 is connected to the fixed limiting unit 21. The first bending assembly 221 corresponds to the position of the first crease positioning portion 211, and the second bending assembly 222 corresponds to the position of the second crease positioning portion 212. It should be noted that when taking the adhesive tape, the part to be bent A21 is fixed on the first bending assembly 221, and the part to be bent A22 is fixed on the second bending assembly 222. When bending, driven by the rotation driving assembly 223, the first bending assembly 221 and the second bending assembly 222 rotate in the same direction at the same time. The part to be bent A21 and the part to be bent A22 move respectively as the first bending assembly 221 and the second bending assembly 222 rotate, so as to realize the bending of the part to be bent A2.

[0045] As a further optimization, the fixed limiting unit 21 is further provided with a first bending limiting portion 213 and a second bending limiting portion 214 for respectively limiting the bending angles of the first bending assembly 221 and the second bending assembly 222. The first bending limiting portion 213 is located in the rotation direction of the first bending assembly 221, and the second bending limiting portion 214 is located in the rotation direction of the second bending assembly 222. In this embodiment, the bending angles of the first bending assembly 221 and the second bending assembly 222 are both right angles.

[0046] It should be noted that in this embodiment, the fixed limiting unit 21, the first bending assembly 221, and the second bending assembly 222 are all located on the same side of the adhesive tape. When the first bending assembly 221 rotates to abut against the first bending limiting portion 213, it stops moving. When the second bending assembly 222 rotates to abut against the second bending limiting portion 214, it stops moving. At this time, the bending angles of the part to be bent A21 and the part to be bent A22 are the same. After bending, the first bending assembly 221 and the second bending assembly 222 do not need to withdraw, but move together with the fixed limiting unit 21 under the drive of the drive module 1, and attach the bent adhesive tape to the position of the head of the battery cell to be pasted with adhesive tape. Thereby, the adhesive tape pasting operation efficiency of the battery cell is improved, which is beneficial to further improving the production operation efficiency of the battery cell.

[0047] In some embodiments, a first adsorbent 215 for fixing the body part of the adhesive tape is provided on the fixed limit unit 21. Second adsorbents 224 for fixing the parts of the adhesive tape to be bent are provided on both the first bending assembly 221 and the second bending assembly 222. The first adsorbent 215 and the second adsorbents 224 adsorb the same side of the adhesive tape. In some embodiments, the fixed limit unit 21, the first bending assembly 221, and the second bending assembly 222 can adsorb and fix the adhesive tape in the vertical direction or in the horizontal direction.

[0048] The tape sticking mechanism provided in this embodiment realizes the offset bending of the parts of the adhesive tape to be bent by staggeredly arranging the first crease positioning part and the second crease positioning part on the fixed limit unit, improves the tape sticking quality, adapts to the tape sticking of the head of the battery cell with a height difference, and meets the operation and production requirements of special battery cells; by providing the first bending assembly and the second bending assembly to respectively perform rotational bending on the first part to be bent and the second part to be bent of the adhesive tape, it not only improves the production efficiency of the tape sticking operation, but also can ensure the quality of creasing and tape sticking, which is beneficial to further improving the production quality of the battery cell products.

[0049] Embodiment 2

[0050] As a further optimization of Embodiment 1, referring to Figure 8 , the rotation drive assembly 223 includes a rotation drive motor 2231, a transmission rotation shaft 2232, a first synchronous pulley 2233, and a second synchronous pulley 2234. The rotation drive motor 2231 is in transmission connection with the transmission rotation shaft 2232. The first synchronous pulley 2233 and the second synchronous pulley 2234 are respectively connected to both ends of the transmission rotation shaft 2232 through transmission belts 2235. The first bending assembly 221 is connected to the rotation shaft of the first synchronous pulley 2233, and the second bending assembly 222 is connected to the rotation shaft of the second synchronous pulley 2234.

[0051] Specifically, the transmission connection mode between the rotation drive motor 2231 and the transmission rotation shaft 2232 is that a first gear 2236 is connected to the drive end of the rotation drive motor 2231, and a second gear 2237 is sleeved on the transmission rotation shaft 2232. The first gear 2236 is meshed and connected with the second gear 2237.

[0052] During operation, when the rotation drive motor 2231 is started, the first gear 2236 rotates under the drive of the rotation drive motor 2231, thereby driving the second gear 2237 to rotate. The transmission rotation shaft 2232 rotates together with the second gear 2237, thereby driving the transmission belts at both ends of the transmission rotation shaft 2232 to move. Under the transmission action of the transmission belts, the first synchronous pulley 2233 and the second synchronous pulley 2234 rotate synchronously and respectively drive the first bending assembly 221 and the second bending assembly 222 to rotate, thereby realizing the bending of the part A2 to be bent.

During operation, the taping mechanism 200 first sucks the adhesive tape from the tape feeder 100, then misaligns and bends the adhesive tape, and then moves the bent adhesive tape to the cell taping station and attaches it to the head of the cell to complete the taping operation.
