The tape on the film roll 301 passes over the roller 302 and extends between the clamping rod 314 and the connecting column 315.

[0043] A cutting mechanism is disposed on the top of the roller 302. The cutting mechanism includes a cutting blade 210 and is used to cut the adhesive tape.

In this setting, the elastic force of the first spring 106 drives the positioning cylinder 104 to reset, thereby moving the limit frame 103 upward.

[0045] like Figures 1 to 9 As shown, further, a second support plate 201 is fixedly mounted on one side of the first support plate 200, a slide bar 214 is fixedly mounted on one side of the top of the second support plate 201, a sleeve 211 is movably sleeved on the slide bar 214, a cutter 210 is fixedly mounted on one side of the sleeve 211, a curved surface 212 is provided at the bottom of the cutter 210, a third spring 215 is movably sleeved on the slide bar 214, and two ends of the third spring 215 are respectively fixedly mounted on the bottom of the sleeve 211 and the top of the second support plate 201.

In this arrangement, as the cutter 210 descends, the stopper 213 is driven downward by the sleeve 211, and the stopper 213 is stuck at the bottom of the block 203. When resetting, the push rod 206 drives the block 203 to move through the stop rod 205 and staggers with the stopper 213. At this time, the elastic force of the third spring 215 drives the sleeve 211 to reset, thereby resetting the cutter 210.

[0047] Embodiment 2:

[0048] like Figures 1 to 9 As shown, further, a first fixed block 306 is fixedly installed on the rocker arm 305, a fourth spring 307 is fixedly installed on one side of the first fixed block 306, and a pull plate 308 is fixedly installed on the other end of the fourth spring 307, a pressure rod 309 is fixedly installed on one side of the pull plate 308, a sliding shaft 310 is installed on the other end of the pull plate 308, a second fixed block 311 is movably sleeved on the sliding shaft 310, one side of the second fixed block 311 is fixedly installed on the rocker arm 305, the other end of the sliding shaft 310 is rotatably connected to a connecting rod 312, the other end of the connecting rod 312 is rotatably connected to a connecting block 313, and one end of the connecting block 313 is fixedly mounted on one end of the clamping rod 314. In this configuration, when the rocker arm 305 rotates to the end of the guide ring 402, the guide ring 402 separates from the pressure rod 309. At this time, the elastic force of the fourth spring 307 drives the pull plate 308 to reset. The pull plate 308 drives the connecting block 313 and the clamping rod 314 to reset through the sliding shaft 310 and the connecting rod 312, and clamps one end of the tape.

[0049] Embodiment three:

[0050] like Figures 1 to 9As shown, in a specific embodiment, a limit shaft 400 is fixedly installed at one end of the swing rod 305, four fixed rods 401 are movably sleeved on the limit shaft 400, a guide ring 402 is fixedly installed at the outer ends of the four fixed rods 401, two sleeves 403 are fixedly installed on the side of the guide ring 402, a sliding column 404 is movably inserted on the sleeve 403, and the bottom of the sliding column 404 is fixedly installed on the top of the bottom plate 100. In this configuration, the guide ring 402 can be lifted and lowered without rotating through the movable connection between the sliding column 404 and the sleeve 403.

[0051] like Figures 1 to 9 As shown, further, a guide block 500 is fixedly installed on the outer side of the support shaft 304, a guide arc surface is arranged on the outer side of the guide block 500, and the convex position and the end of the guide arc surface are respectively located on both sides of the support shaft 304, and a first lever 501 and a second lever 502 are respectively arranged on the bottom of the guide block 500, the first lever 501 and the second lever 502 are respectively located on both sides of the support shaft 304, the height of the first lever 501 is less than the height of the second lever 502, and a first bracket 503 and a second bracket 504 are respectively fixedly installed on one end of the first lever 501 and the second lever 502, and the bottoms of the first bracket 503 and the second bracket 504 are fixedly installed on the top of the base 101. In this arrangement, the support shaft 304 descends while the first lever 501 abuts against the guide block 500, thereby driving the guide block 500 and the support shaft 304 to rotate, and when the guide block 500 is separated from the first lever 501, the rotation stops, at which point the guide block 500 rotates half a circle, and the support shaft 304 rises to cause the guide block 500 to abut against the second lever 502, thereby rotating, and when the guide block 500 is offset from the second lever 502, the rotation stops, at which point the guide block 500 rotates half a circle again.

[0052] The implementation principle of the gluing mechanism for the lithium battery tab of the present embodiment is as follows: when in use, the frame position of the lithium battery is pressed against the top of the cutter 210, and the cutter 210 is driven to descend. When the cutter 210 descends to the roller 302, the cutter 210 cuts the tape, and the cut tape falls on the cushion block 303. The cut tape end is pressed on the roller 302 by the arc surface at the bottom of the cutter 210. When the cutter 210 descends, the stopper 213 is driven to descend through the sleeve 211, and the stopper 213 is stuck at the bottom of the block 203. The lithium battery is continued to be pressed downward to make the cutter 210 continue to descend. The cutter 210 presses against the roller 302 to descend, and the roller 302 drives the first support plate 200 to descend, so that the support plate 200 The support shaft 304 descends, and while the support shaft 304 descends, the first lever 501 abuts against the guide block 500, thereby driving the guide block 500 and the support shaft 304 to rotate, and when the guide block 500 is separated from the first lever 501, the rotation stops, and at this time the guide block 500 rotates half a circle, and the guide block 500 and the support shaft 304 drive the swing rod 305 to rotate, and the swing rod 305 drives the sliding shaft 310 and the pull plate 308 to rotate through the second fixed block 311, thereby rotating the pressure rod 309, and the pressure rod 309 abuts against the guide ring 402 and moves toward the inner side of the guide ring 402, and drives the pull plate 308 to move, and the pull plate 308 pulls the connecting rod 312 through the sliding shaft 310, and the connecting rod 312 pulls the connecting block 313 The clamp rod 314 is moved and tilted. When the lithium battery is against the cushion block 303, the tape sticks to the pole ear of the lithium battery. At this time, the lithium battery is removed, and the elastic force of the first spring 106 drives the positioning cylinder 104 to reset, so that the limit frame 103 moves up, and the limit frame 103 drives the first support plate 200 to rise, and the support shaft 304 to rise. The rise of the support shaft 304 makes the guide block 500 press against the second lever 502, thereby rotating, and stops rotating when the guide block 500 and the second lever 502 are offset. At this time, the guide block 500 rotates half a circle again, and the rotation of the support shaft 304 drives the swing rod 305 to rotate with it. When the swing rod 305 rotates to the end of the guide ring 402, the guide ring 402 and the pressure rod 309 is separated, at this time, the elastic force of the fourth spring 307 drives the pull plate 308 to reset, and the pull plate 308 drives the connecting block 313 and the clamping rod 314 to reset through the sliding shaft 310 and the connecting rod 312, and clamps one end of the tape, and at the same time the swing rod 305 abuts against one end of the top rod 209 and drives the push rod 206 to rotate, and the push rod 206 drives the block 203 to move through the stop rod 205 and staggered with the stop block 213, at this time, the elastic force of the third spring 215 drives the sleeve 211 to reset, so that the cutter 210 is reset, leaving a gap between the cutter 210 and the roller 302, the swing rod 305 drives the connecting column 315 and the clamping rod 314 to move, and pulls one end of the tape to reset through the cutter 210 and the roller 302.
