[0002] Lithium-ion battery is a secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the production and processing of lithium-ion batteries, the surface after winding needs to be glued, so a gluing device is needed. The "double-sided gluing device of a button-type lithium-ion battery film winding machine" disclosed in the application number "CN219800976U" has solved the technical disadvantages of large equipment size and occupying more space. However, in actual use, devices with similar structures still have many defects. For example, the structure of the gluing is relatively simple, and most of them only attach the adhesive tape to the film roll surface, and do not have the function of pressing the adhesive tape to it tightly, so that the corners of the adhesive tape on the film roll surface will be lifted or even displaced and fall off. For this reason, we designed a double-sided gluing device for a lithium-ion battery film winding machine to solve the above problems. Utility Model Content

The output end of the cylinder 703 is fixedly installed with a knife holder 7, and a cutting knife 701 is fixedly installed inside the knife holder 7. The stretching mechanism 4 includes a stretching slide rail 401, a slide plate 402 is slidably installed on the front of the stretching slide rail 401, a clamping cylinder 403 is fixedly installed on the front of the slide plate 402, and a clamping claw 404 is fixedly installed on the output end of the clamping cylinder 403. The gluing mechanism 5 includes a gluing slide rail 501 and a gluing seat 8. A slide frame 502 is slidably installed on the gluing slide rail 501, an electric push rod 503 is fixedly installed on the top of the slide frame 502, two groups of gas rods 802 are slidably installed inside the gluing seat 8, a vacuum suction cup 805 is fixedly connected to the bottom of the gas rod 802, a support spring 804 is fixedly installed on the top of the vacuum suction cup 805, and a pressing rubber pad 801 is fixedly installed on the bottom of the gluing seat 8.

[0026] Based on the above-mentioned structural setting, the double-sided gluing device of the lithium-ion battery film winding machine is composed of a frame plate 1, a transition mechanism 2, a clamping mechanism 3, a stretching mechanism 4 and a gluing mechanism 5, wherein the frame plate 1 is the installation support structure of the device, the transition mechanism 2 is the guiding mechanism of the adhesive paper, with the help of the transition mechanism 2, tension and buffering can be provided to the adhesive paper when it moves, the clamping mechanism 3 clamps and fixes one end of the adhesive paper and cuts it, the stretching mechanism 4 can stretch and migrate the adhesive paper, with the help of the stretching mechanism 4, the cutting length of the adhesive paper can be controlled, and the gluing mechanism 5 can attach the adhesive paper to the surface of the wound electrode. Specifically, during the working process, the frame plate 1 can support and install the overall mechanism when the device is in use, and the front side of the frame plate 1 is rotatably installed with multiple sets of transitions. The transition roller 6 can support the adhesive paper when it is moving, so as to provide tension and buffer for the adhesive paper when it is moving. The slider 202 is slidably installed on the outside of the slide bar 203 inside the mounting frame 201. The height of the adjusting roller 204 can be adjusted by the slider 202 and the slide bar 203. The tension and buffer of the adhesive paper when it is moving can be adjusted by adjusting the height of the adjusting roller 204. When in use, the staff can adjust and control according to the actual operation conditions of the device. The stretching slide rail 401 moves the clamping cylinder 403 left and right through the slide plate 402. The clamping cylinder 403 can clamp and fix one end of the adhesive paper by closing the clamping claw 404. At the same time, the stretching slide rail 401 moves the clamping cylinder 403 to the right to clamp The adhesive tape is stretched, and the stretching length of the adhesive tape can be controlled by controlling the moving length of the clamping cylinder 403. The clamping cylinder 301 pushes the driving clamp block 302 to descend and cooperates with the fixed clamp block 303 to lock the adhesive tape stretched by the clamping claw 404. The gluing slide rail 501 can move the electric push rod 503 to the top of the stretched adhesive tape through the slide 502. The electric push rod 503 can lower the gluing seat 8 and the vacuum suction cup 805 by telescoping. The vacuum suction cup 805 is connected to an external vacuum device through the gas rod 802, so that the vacuum suction cup 805 can adsorb the top surface of the stretched part of the adhesive tape by vacuum. When the vacuum suction cup 805 adsorbs the top surface of the stretched part of the adhesive tape, the cutting cylinder 703 drives the knife to move by contraction. The seat 7 and the cutting knife 701 are lifted, so that the stretched part of the adhesive tape can be cut by the lifted cutting knife 701. When the stretched part of the adhesive tape is cut, the clamping cylinder 403 opens the clamping claw 404, and the electric push rod 503 contracts to drive the adhesive tape adsorbed by the vacuum suction cup 805 to lift up. The glue sticking slide rail 501 moves the adhesive tape adsorbed by the vacuum suction cup 805 to the film winding area. The electric push rod 503 can stick the adhesive tape adsorbed by the vacuum suction cup 805 to the surface of the winding film by lowering the vacuum suction cup 805. When the adhesive tape is pasted on the surface of the winding film, the electric push rod 503 will drive the glue sticking seat 8 to continue to descend. The adhesive tape on the surface of the winding film can be compacted and tightly attached by the glue sticking seat 8, thereby avoiding the situation where the corners are lifted and the displacement falls off due to loose adhesion.To facilitate the processing of the wound film by subsequent equipment, the pressing rubber pad 801 can provide flexible protection when the glue sticking seat 8 presses the adhesive tape, avoiding the situation of friction damage to the adhesive tape surface, so that the wound film can be glued through the glue sticking slide rail 501, the electric push rod 503, and the vacuum suction cup 805. When the device completes gluing on one side of the wound film, the external device flips it over to facilitate the device to glue on the other side, realizing the function of double-sided gluing of the wound film.

[0027] Furthermore, the top of the gas rod 802 is fixedly connected with a confluence pipe 806, and the top of the confluence pipe 806 is fixedly connected with a quick connector 803. The quick connector 803 facilitates the quick connection of the confluence pipe 806 with the air pipe of the external vacuum equipment, and the confluence pipe 806 can merge the two groups of gas rods 802.

[0028] Furthermore, the outer side of the knife seat 7 is threadedly installed with a rotating seat 702. The rotating seat 702 can install and lock the cutting knife 701, and the angle of the cutting knife 701 during operation can be adjusted by the rotating seat 702. By adjusting the cutting knife 701 to the optimal angle, the quality and efficiency of the tape cutting can be improved.

[0029] Furthermore, a threaded rod 205 is rotatably mounted inside the mounting frame 201, and a hand wheel 206 is disposed at the bottom of the threaded rod 205. The threaded rod 205 can adjust the slider 202 up and down by rotating it, and the hand wheel 206 is convenient for the staff to manually rotate the threaded rod 205, thereby facilitating the staff to adjust the adjusting roller 204 up and down.

[0030] Furthermore, a limiting groove 304 is provided at the bottom of the driving clamp block 302, and a roller 305 is rotatably installed on the top of the fixed clamp block 303. The roller 305 can roll and support the adhesive tape when it is stretched and moved, and the limiting groove 304 can press and lock the roller 305, thereby increasing the stability of the driving clamp block 302 and the fixed clamp block 303 when pressing and locking the adhesive tape.

[0031] Furthermore, a fixing plate 101 is fixedly installed on the rear side of the bottom of the frame plate 1, and two sets of ribs 102 are fixedly installed on the top of the fixing plate 101. Among them, the fixing plate 101 can fix the bottom of the frame plate 1, which increases the convenience of device installation, and the ribs 102 increase the stability of the fixing plate 101 when connected to the frame plate 1.
