Description

Technical Field

[0001] The utility model relates to the technical field of battery core production, in particular to a double-sided gluing device for pole pieces and tabs. Background Art

[0002] The main structure of a lithium-ion battery consists of a housing and a lithium-ion battery cell mounted within it. Typically, the cell consists of a positive electrode sheet, an upper separator, a negative electrode sheet, and a lower separator. The positive and negative electrodes are crucial components of a lithium-ion battery cell. During the winding of a lithium-ion battery, insulating tape is typically used to cover the blank area of ​​the positive electrode sheet. This is primarily to prevent burrs from the welding points and the beginning and end of the powder coating from piercing the separator during the welding of the electrode tabs.

[0003] The existing lithium battery pole piece and tab gluing mechanism uses an overall structure to move horizontally to deliver the tape to a vacuum glue suction block, then uses a tape cutter to cut the tape, and then the glue suction block moves the tape horizontally and vertically again to finally stick the tape to the welding point between the pole piece and the tab (i.e., the upper and lower sides of the pole piece). However, the existing pole piece and tab gluing mechanism has a very complex structure, and the gluing action is also very complicated. At the same time, since the equipment may only have one device for gluing tape, for a design where multiple locations on a pole piece require double-sided gluing, multiple rewinding and repeated gluing actions are required.

[0022] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the utility model provides a double-sided gluing device 100 for a pole piece and a pole tab, which includes a first glue disc 10, a second glue disc 20, a cutting group 30, an upper clamp 40 and a lower clamp 50. There is a film transfer space (not shown in the figure) below the cutting group 30, and the film transfer space is a space for the pole piece to stay. When the tape is applied, the pole piece 03 stays in the film transfer space. The upper clamp 40 and the lower clamp 50 are arranged in the film transfer space, and the lower clamp 50 is arranged below the upper clamp 40, and the lower clamp 50 and the upper clamp 40 are arranged on the left and the right. The first glue disc 10 is arranged above the cutting group 30, and the first glue disc 10 is used to carry and release the lower tape 01. The lower clamp 50 is used to clamp the lower tape 01 and pull the lower tape 01 to the right. The second glue disc 20 is arranged on the right side of the cutting group 30, and the second glue disc 20 is used to carry and release the upper tape 02. The upper clamp 40 is used to clamp the upper adhesive tape 02 and pull the upper adhesive tape 02 to the left. The cutting group 30 cuts the pulled upper adhesive tape 02 and the lower adhesive tape 01 downwards.

[0024] During processing, the first adhesive reel 10 releases the lower adhesive tape 01, and the second adhesive reel 20 releases the upper adhesive tape 02. The lower clamp 50 clamps the released lower adhesive tape 01 and pulls it to the right. The upper clamp 40 clamps the released upper adhesive tape 02 and pulls it to the left. The electrode 03 is fed into the film feeding space. Next, the cutting group 30 cuts the pulled upper and lower adhesive tapes 02 and 01 downwards. The cut tapes are applied to the weld between the electrode and the tab (the upper and lower sides of the electrode).

[0025] After releasing the upper tape 01 and the lower tape 02, the pole piece and tab double-sided gluing device 100 of the present invention only needs to use the upper clamp 40 and the lower clamp 50 to pull out the upper tape 01 and the lower tape 02 respectively, and use the cutting group 30 to cut the upper tape 01 and the lower tape 02 to complete the gluing operation. In addition, the structure of the pole piece and tab double-sided gluing device 100 is relatively simple.

[0026] like Figure 1 and Figure 2 As shown, the cutting assembly 30 includes a left cutter 31 and a right cutter 32. The left cutter 31 and the right cutter 32 are spaced apart and can move up and down to perform cutting operations. The left cutter 31 moves downward to cut the lower tape 01, while the right cutter 32 moves downward to cut the upper tape 02.

[0027] like Figure 1 and Figure 2 Shown, lower fixture 50 can be slidably installed with a slide 51, and lower fixture 50 can slide easily in left and right. Preferably, slide 51 is selected as a wooden structure, but according to actual needs, also can adopt plastic structure or metal structure etc.

[0028] like Figure 1 and Figure 2 As shown, the electrode tab double-sided adhesive laminating device 100 of the present invention further includes a mounting frame 60. The first adhesive tray 10, the second adhesive tray 20, the cutting unit 30, and the slide 51 are mounted on the mounting frame 60. The mounting frame 60 defines a through-hole 61 facing the film feed space. The lower clamp 50 and the upper clamp 40 are located on either side of the through-hole 61. The electrode 03 is inserted through the through-hole 61 and then fed into the film feed space.

[0029] like Figure 1 and Figure 2 As shown, the electrode tab double-sided gluing device 100 of the present invention further includes a transparent cover 70 mounted on the mounting frame 60 and covering the left and right cutters 31 and 32. The transparent cover 70 has an opening below. The transparent cover 70 provides protection from accidents caused by misoperation. The transparent cover 70 allows for intuitive and convenient operation of the left and right cutters 31 and 32. Furthermore, the upper clamp 40 is slidably mounted on the transparent cover 70.

[0030] like Figures 1 to 4 As shown, the upper clamp 40 and the lower clamp 50 each include a mounting rod 04, an upper clamp 05, and a lower clamp 06. One end of the lower clamp 05 is fixedly mounted on the mounting rod 04, while one end of the upper clamp 06 is slidably mounted on the mounting rod 04. The upper clamp 05 and the lower clamp 06 are arranged orthogonally to the mounting rod 04, with the upper clamp 05 positioned above the lower clamp 06. The mounting rod 04 is equipped with a sliding handle 07. By moving the upper clamp 05 closer to the lower clamp 06, the upper clamp 05 and the lower clamp 06 can clamp the tape together. The sliding handle 07 can be used to move the upper clamp 40 and the lower clamp 50 left and right, respectively, to facilitate the delivery of the tape into place.

[0031] like Figure 1 and Figure 2 As shown, the pole piece and tab double-sided adhesive laminating device 100 of the present invention further includes a first guide wheel 81 and a second guide wheel 82. The first guide wheel 81 and the second guide wheel 82 are respectively mounted on the mounting frame 60. The first guide wheel 81 is located on the left side of the first adhesive reel 10, and the second guide wheel 82 is located on the left side of the lower clamp 50. The second guide wheel 82 is located below the first guide wheel 81. The lower adhesive tape 02 released from the first adhesive reel 10 passes through the first guide wheel 81 and the second guide wheel 82 in sequence before being input into the lower clamp 50 for clamping. The first guide wheel 81 and the second guide wheel 82 serve to guide the lower adhesive tape 01.

[0032] like Figure 1 and Figure 2 As shown, the pole piece and tab double-sided adhesive laminating device 100 of the present invention further includes a third guide wheel 91, a fourth guide wheel 92, and a fifth guide wheel 93. The fifth guide wheel 93 is located on the right side of the upper clamp 50, the fourth guide wheel 92 is located on the right side of the fifth guide wheel 93, and the third guide wheel 91 is located between the first adhesive disc 10 and the second adhesive disc 20. The third guide wheel 91 is located above the fourth guide wheel 92 and the fifth guide wheel 93. The upper adhesive tape 02 released from the second adhesive disc 20 passes through the third guide wheel 91, the fourth guide wheel 92, and the fifth guide wheel 93 in sequence before being input into the upper clamp 40 for clamping. The third guide wheel 91, the fourth guide wheel 92, and the fifth guide wheel 93 serve to guide the upper adhesive tape 02.
