After the first visual sensor 134 detects the new material tape on the new material tape, the fourth driving component 1421 drives the two fixed jaws 1422 to approach each other to clamp the new material tape, and then the new material tape is cut. At this time, the new material tape cut by the new material tray 20 is conveyed by the material head conveyor assembly 14, and the end of the new material tape is in a vertical state. Then the sixth driving component 1423 drives the fourth driving component 1421 to rotate so that the end of the new material tape is switched from a vertical state to a horizontal state. The third displacement driving component 141 carries the end of the new material tape to one end of the conveying track 22, and then the fourth driving component 1421 drives the two fixed jaws 1422 to move away from each other to release the new material tape. The rotating driving component 113 drives the new material tray 20 to rotate so that the end of the new material tape moves to one end of the material receiving station. In this embodiment, the fourth driving member 1421 is a clamping cylinder, and the sixth driving member 1423 is a rotating cylinder.

[0068] In this embodiment, the third displacement driving component 141 can drive the grabbing component 112 and the rotating driving component 113 to move along the second direction and the third direction, the second direction is the Y direction, and the first direction, the second direction and the third direction are perpendicular to each other. The third displacement driving component 141 can be matched with two linear modules.

[0069] Furthermore, the film supply assembly 23 includes a turntable 231 , which is rotatably connected to the bracket 21 , and the film component is wound around the turntable 231 . When the turntable 231 rotates, the film component is continuously supplied.

[0070] Furthermore, if Figure 6 and Figure 7As shown, the label stripping assembly 24 includes a label stripping block 241, a waste wheel 242 and a seventh driving member 243. The seventh driving member 243 is arranged on the bracket 21. The seventh driving member 243 is drivingly connected to the waste wheel 242. The seventh driving member 243 is used to drive the waste wheel 242 to rotate. A label stripping blade 2411 is arranged on the side of the label stripping block 241 close to the material receiving assembly 25. The waste wheel 242 is located on the side of the label stripping block 241 away from the label stripping blade 2411. The protective film passes through the label stripping blade 2411 of the label stripping block 241 and is wrapped around the waste wheel 242 to separate the material receiving film and the protective film. In this embodiment, the waste wheel 242 and the turntable 231 are both located on the side of the stripping block 241 away from the stripping blade 2411, and the waste wheel 242 is located below the stripping block 241. The protective film is sequentially passed through the turntable 231 and the stripping blade 2411 of the stripping block 241 and is wound around the waste wheel 242. When the seventh driving member 243 drives the waste wheel 242 to rotate, the waste wheel 242 can pull the protective film to achieve continuous supply of the film component. When the protective film passes through the stripping blade 2411, it is transported in the reverse direction. The hardness of the material film is greater than that of the protective film, so the material film will not be reversed, and the material film continues to be transported forward, so that the material film is separated from the protective film. In this embodiment, the seventh driving member 243 is a servo motor.

[0071] Furthermore, if Figure 6-Figure 8 As shown, the material receiving assembly 25 includes a fourth displacement driving component 251 and an adsorption component 252. The adsorption component 252 includes a material suction position and a crimping position. When the adsorption component 252 is located at the material suction position, the separated material receiving film moves to the bottom of the adsorption component 252, and the adsorption component 252 can absorb the material receiving film; when the adsorption component 252 is located at the crimping position, the adsorption component 252 can crimp the material receiving film to the connection position between the new material belt and the old material belt; the fourth displacement driving component 251 is used to drive the adsorption component 252 to move between the material suction position and the crimping position. When working, the fourth displacement driving component 251 first drives the adsorption component 252 to move to the material suction position, and the separated material receiving film moves to the bottom of the adsorption component 252, and the adsorption component 252 absorbs the material receiving film, and then the fourth displacement driving component 251 first drives the adsorption component 252 to move to the crimping position, and the adsorption component 252 crimps the material receiving film to the connection position between the new material belt and the old material belt, and the adsorption component 252 stops adsorption.

The bottom of the front mark suction block 2521 can vacuum adsorb the material connection film. When connecting the material, the bottom of the front mark suction block 2521 presses the material connection film to the connecting position of the new material belt and the old material belt, so as to realize the top surface connection of the new material belt and the old material belt; at this time, since the first elastic member is provided between the top of the front mark suction block 2521 and the connecting plate, when the front mark suction block 2521 adsorbs the material connection film at the material suction position, and when the front mark suction block 2521 presses the new material belt and the old material belt, they are all elastic contacts, so as to prevent the front mark suction block 2521 from crushing the material belt and the material connection film.

[0073] Furthermore, the adsorption component 252 also includes a rear mark suction block 2522, which is slidably connected to the connecting plate along the Z direction; a second elastic member (as shown in the figure) is arranged between the top of the rear mark suction block 2522 and the connecting plate; when the adsorption component 252 is in the crimping position, the front mark suction block 2521 crimps part of the splicing film to the connecting position of the new material tape and the old material tape; the rear mark suction block 2522 folds the part of the splicing film that is not arranged above the connecting position of the new material tape and the old material tape, so as to fold the splicing film to the bottom of the new material tape and the old material tape. In this embodiment, the rear mark suction block 2522 is located on the side of the front mark suction block 2521 close to the mark stripping component 24. When the first elastic member and the second elastic member are not compressed, the bottom surfaces of the front mark suction block 2521 and the rear mark suction block 2522 are flush, and the front mark suction block 2521 and the rear mark suction block 2522 can jointly absorb the splicing film. During the crimping process of the front mark suction block 2521, the connecting plate continues to be pressed down. At this time, the front mark suction block 2521 compresses the first elastic member under the stop of the new material belt and the old material belt, and the rear mark suction block 2522 continues to move downward, so that the front mark suction block 2521 and the rear mark suction block 2522 are staggered. At this time, the rear mark suction block 2522 folds the part of the splicing film that is not set above the connecting position of the new material belt and the old material belt, so as to fold the splicing film to the bottom of the new material belt and the old material belt.

[0074] In this embodiment, the fourth displacement driving component 251 includes a first linear module and a second linear module, the second linear module is connected to the output end of the first linear module, the first linear module is used to drive the second linear module to move along the first direction, the conveying track 22 extends along the second direction, and the connecting block 2511 is arranged at the output end of the second linear module, and the second linear module is used to drive the connecting block 2511 to move along the third direction.

[0075] In this embodiment, the first elastic member and the second elastic member are both springs, and the connecting block 2511 is provided with a stop boss 25111, and the stop boss 25111 is located above the front mark suction block 2521 and the rear mark suction block 2522, the first elastic member is located between the stop boss 25111 and the front mark suction block 2521, and the second elastic member is located between the stop boss 25111 and the rear mark suction block 2522, and the front mark suction block 2521 and the rear mark suction block 2522 are also connected with a hooking rod 2523, and the hooking rod 2523 is hooked above the stop boss 25111, so that the front mark suction block 2521 and the rear mark suction block 2522 will not separate from the connecting block 2511 under the elastic force of the first elastic member and the second elastic member.

A gap is provided between the connection position of the new material belt and the old material belt and the conveying track 22. The folding blade 2531 is flush with the gap. The eighth driving member is drivingly connected to the folding film pushing block 253. The eighth driving member is used to drive the folding blade 2531 to move in the direction close to the gap to push the folding position of the splicing film into the gap. After the rear suction mark block 2522 folds the splicing film, the fourth displacement driving component 251 drives the front suction mark block 2521 and the rear suction mark block 2522 to rise. At this time, the eighth driving member drives the folding blade 2531 to move in the direction close to the gap to push the folding position of the splicing film into the gap. Finally, the front suction mark block 2521 presses the new material belt and the old material belt again, so that both sides of the new material belt and the old material belt are connected through the splicing film to complete the splicing.
