[0056] Specifically, the sliding member 7 in the embodiment is composed of a sliding rail and a slider mounted on the sliding rail.

[0057] The specific gluing action process in the embodiment is as follows:

[0058] Feeding: the disc type wound adhesive tape is installed on the tray 3, the open end of the adhesive tape is wound through the glue placing float roller and the material guide roller, and passes through the gap between the glue pressing clamp 1045 and the glue pressing roller 1044.

[0059] Taking material: the vacuum chuck is moved and pressed on the adhesive tape by the taking material lifting cylinder and the moving cylinder. The cutter 16 is driven by the lifting cutting cylinder 15 to cut the adhesive tape. Since the clamping part of the glue pulling clamp 102 has an inclination angle, the glue removing plate 1022 is retracted by the clamping cylinder 1024, so that the glue clamping roller 1026 presses the adhesive tape on the inclined clamping part on the vacuum chuck, further improving the taking material stability and accuracy of the adhesive tape on the vacuum chuck, thereby enhancing the precise fitting of the subsequent adhesive tape and tab bonding.

[0060] Piezoelectric core and tab: the core is installed on the turntable. The tab is bent and enters between the pressing plate 12 and the pre-pressing plate 14 through the rotation of the turntable. The bottom of the core is supported by the pressing plate 12 driven by the pressing lifting cylinder 11 to prevent displacement during bonding. The end of the tab is pre-pressed by the pre-pressing plate 14 driven by the pre-pressing lifting cylinder 13 to prevent the end of the tab from affecting the adhesive.

[0061] Gluing: the vacuum chuck is moved above the core tab by the taking material lifting cylinder and the moving cylinder. The adhesive tape on the vacuum chuck is bonded on the core tab in the shape of "I" by the descent of the taking material lifting cylinder. At this time, the vacuum chuck is loosened and reset. The adhesive roller 8 is moved to the middle of the "I" shaped adhesive tape by the driving member 9 and the gluing lifting cylinder 203. The adhesive roller 8 is lowered and moved under the drive of the driving member 9, so that the adhesive roller 8 drives the adhesive tape to move in the shape of "L", thereby completing the U-shaped bonding of the adhesive tape and the tab.

[0062] In conclusion, the adhesive roller 8 is flexibly pressed against the surface of the adhesive tape, and the adhesive tape is rolled and adhered along the outer edge of the tab, which improves the firmness and reliability of the adhesive, enables the adhesive tape to be uniformly adhered to the tab, ensures accurate adhesion between the adhesive tape and the tab, and further improves the overall performance and safety of the battery tab, thereby improving the production efficiency and quality of the adhesive.

The driving end of the adhesive clamping cylinder is connected to the gripper, so that the adhesive clamping cylinder can drive the gripper to rotate around the hinge shaft. The clamping cylinder is mounted on the adhesive clamping plate, and the telescopic end of the clamping cylinder extends toward the adhesive clamping roller and is connected to the adhesive release plate.

9. The adhesive applicator mechanism for attaching U-shaped adhesive to the electrode tabs according to claim 8, characterized in that: The degumming plate has an inclined clamping surface at the end near the clamping roller, and an angle is formed between the clamping roller and the clamping surface for clamping the tape.

10. The adhesive application mechanism for attaching U-shaped adhesive to the electrode tabs according to claim 9, characterized in that: The positioning clamp includes a movable adjusting block, an adjusting cylinder, a clamping positioning cylinder disposed on the movable adjusting block, and a pressure roller. The adjusting cylinder is installed on the side of the support plate, and the telescopic end of the adjusting cylinder is connected to the movable adjusting block. The pressure roller and the clamping positioning cylinder are both installed on one side of the movable adjusting block. The telescopic end of the clamping positioning cylinder extends to the outer side of the pressure clamp and is connected to the pressure clamp. A gap for clamping the tape is formed between the pressure clamp and the pressure roller.
