[0025] In the present invention, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0026] The following is a detailed description of the implementation of the present invention in conjunction with the specific drawings:

[0027] Figure 1 A schematic diagram of the structure of a battery cell electrode gluing device provided in this application is shown in FIG.

The device is a sliding glue sticking device, and the glue feeding component 2, the glue cutting component 3 and the glue clamping component 4 are all detachably connected to the base 1, which improves the environmental adaptability of the electrode chip gluing device, facilitates assembly and disassembly, and occupies less space.

[0028] The adhesive tape required for wrapping the adhesive tape on the adhesive tape wheel 21 is arranged on the base 1, the first roller 22 is arranged on the side close to the adhesive tape wheel 21, the second roller 23 is arranged on the side close to the adhesive tape cutting assembly 3, the first roller 22 and the second roller 23 are arranged on the same straight line in the vertical direction, and are used to send the adhesive tape to the adhesive tape cutting assembly 3. The adhesive pressing roller 24 is arranged on the side close to the adhesive tape clamping assembly 4, the adhesive pressing roller 24 and the second roller 23 are arranged on the same straight line in the horizontal direction, and the base 1 is provided with a guide rail (not shown in the figure), and the adhesive pressing roller 24 slides and rolls the adhesive tape in the horizontal direction. The counter is electrically connected to the second roller 23, and the counter is arranged on the side opposite to the second roller 23 on the base 1, and is used to calculate the adhesive tape length of the adhesive tape according to the number of turns of the second roller 23. When the length reaches the preset adhesive tape length, the second roller 23 stops rotating. Different preset lengths are set during the adhesive tape process of different battery cell pole pieces to avoid waste caused by sending out too long adhesive tape.

[0029] A first groove 11 is provided on the base 1, and the first groove 11 is provided at the bottom of the base 1. The first groove 11 is used to place the electrode chip to be glued. The glue clamping component 4 and the glue cutting component 3 are respectively provided on both sides of the first groove 11. The glue clamping component 4 includes a shell 41 and a slider 43 provided inside the shell and slidably connected to the shell. A clamp 42 is provided at one end close to the first groove 11, and a spring is provided between the two clamping arms of the clamp 42.

The push rod 44 pushes the shell to move horizontally toward one end of the glue cutting component 3, so as to pull the remaining tape after the glue cutting component 3 is cut off back to a suitable position for glue sticking again.

[0030] The rubber cutting assembly 3 is arranged on the side of the first groove 11 away from the rubber clamping assembly 4, wherein the upper clamping block 31 is detachably connected to the base 1 by bolts, a second groove 34 is arranged on the central axis of the upper clamping block 31, a cutter 33 is arranged inside the second groove 34, and the cutter 33 moves outward to cut the tape, the lower clamping block 32 is symmetrically arranged with the upper clamping block 31, and the upper clamping block 31 is slidably connected with the lower clamping block 32.

[0032] The clamping head 42, the first roller 22, the second roller 23 and the glue pressing roller 24 are all provided with a silicone coating to increase the friction force during the glue feeding and glue laminating process.

[0033] In a complete glue application process, push the push rod 44 to make the glue clamping device 4 close to the glue cutting device 3, slide the slider 43 to open the clamp 42, release the slider after clamping the tape, and push the lower clamp 32 away from the upper clamp 31.

In this glue application process, no cylinder is used to push the glue, and a balanced clamping force is achieved at the same time, which occupies less space and has higher applicability.

[0034] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
