[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments

[0031] As Figures 1 to 6 shown, in this embodiment, a film pasting mechanism for a battery half piece includes a film front detection structure 1, a diaphragm strip cutting structure 2 and a membrane strip clamping structure 3, and the specific structures are described as follows

[0032] The pre-membrane detection structure 1 includes a pre-membrane shooting camera 101 and pre-membrane conveying rollers 102. A pre-membrane conveyor belt 103 is drivingly connected between the pre-membrane conveying rollers 102. The pre-membrane shooting camera 101 is located in front of the pre-membrane conveyor belt 103; The pre-membrane detection structure 1 includes a pre-membrane detection base 104. A pre-membrane blocking frame 105 is slidably connected to the pre-membrane detection base 104 along the horizontal direction. A pre-membrane blocking cylinder 106 is fixed to the upper end of the pre-membrane blocking frame 105. The driving end of the pre-membrane blocking cylinder 106 is vertically downwardly connected to a pre-membrane blocking plate 107. The pre-membrane blocking plate 107 is located above the pre-membrane conveyor belt 103; A pre-membrane detection plate 108 is provided in front of the pre-membrane detection base 104. A pre-membrane detection hole position 109 is provided in the middle of the pre-membrane detection plate 108. A pre-membrane detection light source 110 is provided above the pre-membrane detection hole position 109. The pre-membrane shooting camera 101 is located below the pre-membrane detection hole position 109; A pre-membrane adjustment cylinder is fixed to the pre-membrane detection base 104. The driving end of the pre-membrane adjustment cylinder is horizontally connected to the lower end of the pre-membrane blocking frame 105. A pre-membrane adjustment slide rail 111 is installed at the lower end of the pre-membrane detection base 104. The pre-membrane blocking frame 105 slides on the pre-membrane adjustment slide rail 111.

[0033] After the battery half-cells in the front are welded with welding wires, they enter the pre-membrane detection plate 108. The pre-membrane detection light source 110 provides light. The pre-membrane shooting camera 101 detects the battery half-cells. Then, according to the requirements of the size and position, the pre-membrane adjustment cylinder controls the pre-membrane blocking frame 105 to move back and forth on the pre-membrane detection base 104. After aligning the position, the pre-membrane blocking cylinder 106 controls the pre-membrane blocking plate 107 to move downward, which is used to block the entry of the next batch of battery half-cells into the film inserting strip track 316, so that the previous batch of battery half-cells can be added to the film strip without interference. The previous batch of battery half-cells enter below the film cutting and strip structure 2 under the drive of the pre-membrane conveyor belt 103.

[0034] At the position of the film cutting strip, the film strip cutting structure 2 includes a film roll placement rack 201 and a film strip cutting rack 202. A film cutting seat 203 and a film pressing seat 204 are installed on the film roll cutting rack. The film pressing seat 204 moves along the vertical direction. A cutting shaft 205 moves along the horizontal direction on the film pressing seat 204. A cutting knife 206 is installed on the cutting shaft 205. Cutting guide grooves 207 are provided on both the film cutting seat 203 and the film pressing seat 204. The lower end of the cutting knife 206 moves within the cutting guide groove 207. A film roll fixed roller 208 and a film roll movable roller 209 are provided on the film roll placement rack 201. A film roll adjustment slide rail 210 is fixedly installed on the film roll placement rack 201 along the vertical direction. One end of the film roll movable roller 209 slides on the film roll adjustment slide rail 210. A deviation rectifying fixing plate 211 is fixed on the film strip cutting rack 202. A deviation rectifying cylinder 212 is installed on the deviation rectifying fixing plate 211. The fixed end of the deviation rectifying cylinder 212 is vertically downwardly connected to a deviation rectifying upper and lower plate 213. A deviation rectifying left and right plate 214 slides along the horizontal direction on the film cutting seat 203. The deviation rectifying upper and lower plate 213 is above the deviation rectifying left and right plate 214. A cutting knife motor 215 is installed at the upper end of the film strip cutting rack 202. The driving end of the cutting knife motor 215 is connected to a cutting knife synchronous pulley 216. The cutting knife synchronous pulley 216 is drivingly connected to a cutting knife 206 synchronous belt. A cutting knife slide rail 217 is installed on the film pressing seat 204. A cutting knife support 218 is slidably connected to the cutting knife slide rail 217. The cutting knife 206 synchronous belt is connected to one side of the cutting knife support 218. The cutting shaft 205 is installed at the lower end of the cutting knife support 218.

[0035] The film roll fixed roller 208 of the film roll placement rack 201 holds the wound film. When the film roll movable roller 209 moves up and down along the film roll adjustment slide rail 210, it ensures the flatness of the film after passing through the film roll movable roller 209. After the film enters the film strip cutting rack 202, the film strip deviation sensors 219 on both sides of the film strip cutting rack 202 sense the deviation of the film. The deviation rectifying cylinder 212 controls the deviation rectifying upper and lower plate 213 to press down, pressing the film on the film left and right plates. The film left and right plates move left and right in the horizontal direction until the film strip deviation sensors 219 no longer sense the deviation of the film. The deviation rectifying upper and lower plate 213 rises, releasing the film. The film continues to move forward and enters below the cutting knife support 218. The film pressing cylinder 220 at the top of the film strip cutting rack 202 controls the film pressing seat 204 to move downward. The film pressing seat 204 presses the film on the film cutting seat 203. The cutting knife motor 215 controls the rotation of the cutting knife synchronous pulley 216. Under the action of the cutting knife 206 synchronous belt, the cutting knife support 218 moves horizontally along the cutting knife slide rail 217. The cutting knife 206 rotating on the cutting shaft 205 moves horizontally along the cutting guide groove 207 to perform multi-strip cutting on the film. Then the film pressing seat 204 rises, waiting for the subsequent removal of the cut film strips.

[0036] In terms of the film clamping strip, the film clamping strip structure 3 includes a film clamping strip bottom plate 301, a film clamping strip moving seat 302, and a film clamping strip side frame 303. The film clamping strip moving seat 302 moves along the front-back direction on the film clamping strip bottom plate 301, and the film clamping strip side frame 303 moves along the left-right direction on the film clamping strip moving seat 302. A film clamping strip fixed end 304 is installed on the inner side of the film clamping strip side frame 303, and a film clamping strip movable end 305 is elastically connected to the upper end of the film clamping strip fixed end 304; a side plate moving motor 306 is installed on the film clamping strip moving seat 302, a side plate moving lead screw is rotatably connected to the side plate moving motor 306, the side plate moving lead screw is drivingly connected to a side plate moving nut 307, the side plate moving nut 307 is fixedly connected to a side plate moving flat plate 308, side plate moving wheels 309 are installed on both sides of the side plate moving flat plate 308, a side plate inclined groove 310 is provided on the film clamping strip side frame 303, and the side plate moving wheels 309 are movably located in the side plate inclined groove 310; a film clamping strip moving motor 311 is installed at the end of the film clamping strip side frame 303, the driving end of the film clamping strip moving motor 311 is drivingly connected to a film clamping strip moving belt 312 through a synchronous pulley, the film clamping strip fixed end 304 is connected to the film clamping strip moving belt 312, a film clamping strip slide rail 313 is horizontally installed on the film clamping strip side frame 303, and the film clamping strip fixed end 304 slides on the film clamping strip slide rail 313; film clamping strip lifting cylinders 314 are installed on both sides of the film clamping strip side frame 303, a film clamping strip pressing strip 315 is connected to the driving end of the film clamping strip lifting cylinder 314, and the film clamping strip pressing strip 315 presses on the film clamping strip movable end 305.

[0037] A moving seat motor 319 is installed on the film clamping strip bottom plate 301. The film clamping strip moving seat 302 is driven by a moving seat synchronous pulley and a moving seat synchronous belt 320 to move to the position of the film strip cutting frame 202. The film clamping strip lifting cylinder 314 controls the film clamping strip pressing strip 315 to move downward, pressing and opening one end of the inner side of the film clamping strip movable end 305. After the film clamping strip lifting cylinder 314 controls the film clamping strip pressing strip 315 to rise again, under the elastic action, the film clamping strip movable end 305 clamps the film strip on the film clamping strip fixed end 304. The film clamping strip moving seat 302 controls the entire group of film clamping strip fixed ends 304 to move to the rear end of the film strip inserting track 316. An film strip inserting lifting cylinder 317 is provided below the middle of the film strip inserting track 316. The driving end of the film strip inserting lifting cylinder 317 is vertically upward connected to a film strip inserting lifting plate 318. The film strip inserting lifting cylinder 317 raises the battery half piece upward through the film strip inserting lifting plate 318 and waits for the subsequent insertion of the film strip.

[0038] Specifically, in order to satisfy the requirement that the membrane strips are dispersed to different interval positions of the battery half sheet, the clamping membrane strip moving motor 311 disperses the interval of the fixed end 304 of the clamping membrane strip through the clamping membrane strip moving belt 312 after clamping the membrane strip. After the membrane strip is inserted into the interval of the battery half sheet, the side plate moving motor 306 controls the rotation of the side plate moving screw rod, and the side plate moving flat plate 308 with the side plate moving nut 307 moves backward. Under the relative action of the side plate moving wheel 309 and the side plate inclined groove 310, the clamping membrane strip side frame 303 moves outward, ensuring that the fixed end 304 and the movable end 305 of the clamping membrane strip will not affect the subsequent conveyance of the battery half sheet and the membrane strip.

[0039] It should be noted that the above specific implementation manners are only the preferred embodiments of the present invention and the applied technical principles. Any changes or substitutions that are easily conceivable by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
