[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing the specific embodiments, and are not intended to limit the utility model.

[0023] Please refer to Figures 1 to 3A gluing mechanism includes a glue supply component 12 and a glue applying component 11. The glue supply component 12 provides a glue paper segment 14 for the glue applying component 11. The glue paper segment 14 includes a top segment 141 and a side segment 142 connected to each other. The glue applying component 11 includes a top glue head 114 and a side glue head 113. The top glue head 114 is used to grab the top segment 141 to adhere the top segment 141 to the bottom surface of the battery cell. The side glue head 113 is used to grab the side segment 142 to adhere the side segment 142 to the side of the battery cell. The side glue head 113 can be flipped relative to the top glue head 114 and can move downward in the longitudinal direction Z relative to the top glue head 114. In this embodiment, the top segment 141 is first adhered to the bottom surface of the battery cell, that is, the bottom surface portion a3, by the top glue head 114. Then, the side glue head 113 is flipped relative to the top glue head 114 to adhere the side segment 142 to the side of the battery cell, completing the gluing. It should be noted that after the side glue head 113 is flipped over, it can move downward a certain distance along the longitudinal direction Z relative to the top glue head 114 during the process of sticking the side segment 142 to the side portion a2. In this way, the wrinkles at the transition between the top segment 141 and the side segment 142 can be eliminated, and the phenomenon of wrinkles on the adhesive tape at the transition between the bottom portion a3 and the side portion a2 can be effectively avoided, thereby improving the quality of gluing.

[0024] In this embodiment, a third negative pressure hole is provided on both the top glue head 114 and the side glue head 113 . The third negative pressure hole is connected to a negative pressure generator to generate negative pressure for adsorbing and grabbing the adhesive tape segment 14 .

[0025] Furthermore, the top adhesive head 114 is configured with a first working plane 1140, and the side adhesive head 113 is configured with a second working plane 1130. Third negative pressure holes are provided within the first and second working planes 1140 and 1130, and the second working plane 1130 is not higher than the first working plane 1140. This arrangement ensures that after the side adhesive head 113 is flipped over, the adhesive tape section 14 does not form wrinkles at the transition between the bottom and side surfaces of the battery cell.

The adjustment plate 112 is slidably mounted on the frame plate 13. The side adhesive heads 113 are rotatably mounted on the end of the adjustment plate 112 away from the frame plate 13. The adjustment plate 112 is provided with a first driving member 111 for driving the side adhesive heads 113 to rotate. Optionally, the first driving member 111 is a cylinder, one end of which is hinged to the adjustment plate 112 and the other end is hinged to the side adhesive heads 113.

[0027] In this embodiment, a hinge plate 115 is fixedly mounted on the side rubber head 113 , and the hinge plate 115 is rotatably connected to the adjustment plate 112 via a pin 116 .

[0028] In the embodiment, the adjusting plate 112 is slidingly installed on the shelf plate 13 through the slide rail sliding block assembly. Specifically, the adjusting plate 112 can move relative to the shelf plate 13 to approach or move away from the side surface of the battery cell. Further, the adhesive tape feeding mechanism 1 further comprises a first support beam 15 and a linear module 16, the first support beam 15 is installed on the rack, the linear module 16 is arranged on the first support beam 15, the shelf plate 13 is installed on the linear module 16 and is driven by the linear module 16 to move along the longitudinal direction Z.

[0029] The top adhesive head 114 is slidingly installed on the adjusting plate 112 through the slide rail sliding block assembly, and the adjusting plate 112 is provided with a second stop block 1142, and a buffer spring 1141 is arranged between the top adhesive head 114 and the second stop block 1142.

[0030] In use, the linear module 16 drives the shelf plate 13, i.e. the top adhesive head 114 and the side adhesive head 113, to approach the bottom surface of the battery cell along the longitudinal direction Z downwards until the top adhesive head 114 adheres the top end section 141 to the bottom surface of the battery cell, i.e. the bottom surface part a3, and in the process, the buffer spring 1141 is compressed to play a buffering role; then, the first driving member 111 acts on the side adhesive head 113 to make it turn ninety degrees downwards, in the process, the adjusting plate 112 continues to move slowly downwards along the longitudinal direction Z, and the adjusting plate 112 moves towards the side surface of the battery cell to tightly adhere the side section 142 to the side surface of the battery cell, i.e. the side surface part a2. The continuous slow downward movement of the adjusting plate 112 can ensure that no wrinkles are generated at the transition between the top end section 141 and the side section 142.

[0031] In the embodiment, the adhesive tape feeding assembly 12 comprises a first traction part 122 and a second traction part 123, the second traction part 123 can move relative to the first traction part 122 to approach or move away from the first traction part 122, the adhesive tape 121 is transversely arranged between the first traction part 122 and the second traction part 123, and the adhesive tape feeding assembly 12 further comprises a cutting knife 124, the cutting knife 124 can approach or move away from the adhesive tape 121 transversely arranged between the first traction part 122 and the second traction part 123 along the longitudinal direction Z, for cutting the adhesive tape 121 to form the adhesive tape section 14. It should be noted that before the cutting knife 124 works, the top adhesive head 114 and the side adhesive head 113 have approached the adhesive tape feeding assembly 12 and adsorbed and fixed the adhesive tape 121.
