[0009] By adopting the above technical solution, by setting up the assembly components, the assembly base can cooperate with the positioning columns and the assembly top plate, and a stable frame structure is formed by the assembly base, the positioning columns and the assembly top plate, which can provide stable support for the overall structure of the energy supply component, the conduction component and the synchronization mechanism, and the current assembly base can be assembled on another identical assembly top plate through its own clip-on structure, so that the number of energy supply components, conduction components and synchronization mechanisms assembled can be synchronized with the current assembly components, thereby achieving the effect of subsequent synchronous cutting of the insulating film.

[0010] The present invention is further configured as follows: the energy supply assembly includes an energy supply hydraulic cylinder, an adjusting piston and a guide air cylinder; the energy supply hydraulic cylinder is fixedly connected to the bottom of the assembly base; the adjusting piston is fixedly connected to the output end on the rear side of the energy supply hydraulic cylinder; the guide air cylinder is connected to the rear side of the energy supply hydraulic cylinder; and the surface of the adjusting piston is slidably connected to the inner side of the guide air cylinder.

[0011] By adopting the above technical solution and setting up an energy supply component, the energy supply hydraulic cylinder can cooperate with the adjusting piston and the guide air cylinder. The energy supply hydraulic cylinder is an electric hydraulic cylinder device in the existing technology. After being connected to an external PLC controller and an external power supply, the preset program of the PLC can be used to achieve the effect of pushing and pulling the adjusting piston, so that the adjusting piston can change the gas content in the space of the guide air cylinder and achieve the purpose of delivering the gas to the conduction component.

[0012] The present invention is further configured as follows: the conduction component includes a bifurcated tube, a synchronous tube and an adjusting pneumatic rod, the bifurcated tube is connected to the rear side of the guide air cylinder, the synchronous tube is connected to the top of the bifurcated tube, the adjusting pneumatic rod is connected to the tops of both sides of the bifurcated tube, and the bottom of the adjusting pneumatic rod is fixedly connected to both sides of the rear side of the top of the assembly base.

[0013] By adopting the above technical solution, through setting up a conduction component, the bifurcation tube can cooperate with the synchronization tube and the adjusting pneumatic rod, and three air paths are formed by the bifurcation tube and the synchronization tube. The gas delivered by the energy supply component can be delivered to the adjusting pneumatic rod through the bifurcation tube respectively, so that the adjusting pneumatic rod can change its own position when supporting the guide component through the change of internal gas. The synchronization tube can connect the gas delivery to another identical synchronization tube, so that each synchronization tube can synchronize the gas in the bifurcation tube and the adjusting pneumatic rod, so that each adjusting pneumatic rod can synchronize the position of each adjusting pneumatic rod supporting the guide component when any energy supply component changes the internal gas content, so as to maintain the synchronization required for synchronous cutting.

[0014] The present invention is further configured as follows: the guide assembly includes an insulating film feeder, a guide rail, a positioning frame, a spring plate and a guide rotating rod, the insulating film feeder is fixedly connected to the output end of the top of the adjusting pneumatic rod, the guide rail is fixedly connected to the front side of the insulating film feeder, the positioning frame is fixedly connected to the front side of the bottom of the guide rail, the spring plate is slidably arranged on the inner side of the positioning frame, and the two guide rotating rods are respectively rotatably connected to the top and bottom of the inner side of the spring plate.

[0015] With the above technical solution, by providing a guide assembly, the insulating film feeder can cooperate with the guide rail, positioning frame, spring plate and guide rotating rod. The insulating film feeder is a power battery insulating film conveying device with a built-in electric conveyor roller in the prior art. It can temporarily store the power battery insulating film and can convey the power battery insulating film to the guide rotating rod through its own electric conveyor roller structure, ultimately providing the required battery insulating film for cutting by the synchronization mechanism. The guide rail is a transverse rail structure that can provide guidance and limit for the forward and backward movement of the positioning frame. The spring plate is an existing elastic reset structure consisting of two sliding structures and a tension spring structure. It can slide freely within the positioning frame. According to the adjustment of the spacing between the guide rotating rods, the spacing between the two sliding structures and the length of the tension spring structure itself can be changed when the spring plate is within the positioning frame. Therefore, under the action of the elastic force of the tension spring structure itself, the two sliding structures together with the guide rotating rod connected thereto can be pulled toward the center of the tension spring structure, ultimately achieving the effect of allowing the guide rotating rod to limit the power battery insulating film, thereby providing guidance for the power battery insulating film when it is conveyed to the synchronization mechanism.

[0017] By adopting the above technical solution, through setting a limit component, the limit column can cooperate with the extension plate and the positioning rail. The extension plate is limited by the limit column, so that the positioning rail can be placed above the limit column to adapt to the cutting movement trajectory required by the cutting component. The positioning rail can guide the movement of the synchronization component so that the synchronization component can move back and forth up and down inside it.

[0018] The present invention is further configured as follows: the transmission assembly includes a transmission base, a servo motor and a transmission turntable, the transmission base is fixedly connected to the front side of the extension plate, the servo motor is fixedly connected to both sides of the transmission base, and the transmission turntable is fixedly connected to the output end of the servo motor on the side away from the transmission base.

[0019] By adopting the above technical solution, through setting up a transmission assembly, the transmission base can cooperate with the servo motor and the transmission turntable. The servo motor provides a structure for the axial rotation power started by an external PLC controller and an external power supply in the existing technology. By limiting the servo motor by the transmission base, the servo motor can drive the transmission turntable to rotate, thereby realizing that the transmission turntable drives the synchronization assembly to move circumferentially.

[0020] The present invention is further configured as follows: the synchronization component includes a synchronization slide rod, a synchronization guide rod and a synchronization transmission rod, the synchronization slide rod is slidably connected to the inner side of the positioning rail, the synchronization guide rod is fixedly connected to the bottom of the synchronization slide rod, the synchronization guide rod is rotationally connected to the transmission turntable on the side close to the transmission turntable, and the synchronization transmission rod is fixedly connected to the bottom of the synchronization slide rod.

[0021] By adopting the above technical solution, by setting up a synchronization component, the synchronization slide bar can cooperate with the synchronization guide bar and the synchronization transmission bar. The synchronization guide bar rotates with the transmission turntable, performs circumferential motion around the center point of the rotation of the transmission turntable, and drives the synchronization slide bar to move together. The synchronization slide bar can slide back and forth up and down under the limit within the positioning track, thereby driving the synchronization transmission bar connected to it to move back and forth up and down. The synchronization transmission bar can connect the current synchronization slide bar with another identical synchronization slide bar to achieve the effect of driving another identical synchronization slide bar to perform up and down reciprocating motion together.

[0022] The present invention is further configured as follows: the cutting assembly includes a transmission top plate, a guide slide rail and a cutting plate, the transmission top plate is fixedly connected to the inner side of the synchronization slide rod, the two guide slide rails are respectively opened on both sides of the bottom of the transmission top plate, and the cutting plate is fixedly connected to the front side of the bottom of the transmission top plate.

[0023] By adopting the above technical solution, through setting up a cutting component, the transmission top plate can cooperate with the guide slide rail and the cutting plate. The transmission top plate can drive the cutting plate to move up and down reciprocatingly along with the synchronous slide rod, so that the insulating film can be cut when the cutting plate contacts the insulating film supported on the conveying component, and the guide slide rail can limit the movement of the transmission top plate on the conveying component, thereby increasing the stability of the cutting plate during movement.

[0024] The present invention is further configured as follows: the conveying assembly includes an electric conveying roller, a feeding tray and a guide slide bar, the electric conveying roller is fixedly connected to the front side of the inner side of the extension plate, the feeding tray is fixedly connected to the front side of the electric conveying roller, and the two guide slide bars are respectively fixedly connected to the two sides of the top of the feeding tray, and the top of the guide slide bar surface is slidably connected to the inner side of the guide slide rail.

[0025] By adopting the above technical solution, by setting up a conveying component, the electric conveyor roller can cooperate with the feeding tray and the guide slide bar. The electric conveyor roller is an insulating film conveying device composed of an electric roller group structure in the prior art, and can convey the insulating film forward through its own two conveying roller structures. The electric conveyor roller limits the feeding tray with the transmission base as the support point, so that the power battery insulating film can be stably conveyed into the electric conveyor roller and the insulating film can be conveyed to the feeding tray, and the guide slide bar can guide the movement of the guide rail to increase the stability of the transmission top plate and the cutting plate during movement.

[0026] Compared with the prior art, the present invention provides a multi-layer synchronous cutting device for power battery insulation film, which has the following beneficial effects: This multi-layer synchronous cutting device for power battery insulating films is provided with an adaptable mechanism, wherein the assembly component can cooperate with the energy supply component, the conductive component and the guide component. By assembling the current assembly component with another identical assembly component, the energy supply component, the conductive component and the synchronous mechanism can be assembled synchronously with it, thereby achieving the effect of subsequently cutting multiple power battery insulating films. The energy supply component can change the height of each conductive component when supporting the guide component by adjusting the air pressure, so that each guide component can adapt to the orientation required by the current synchronous mechanism during cutting, thereby improving the stability of the insulating film when cutting in the synchronous mechanism; This is a multi-layer synchronous cutting device for power battery insulating film. By setting a synchronization mechanism, the limiting component can cooperate with the transmission component, synchronization component, cutting component and conveying component. The moving trajectory of the synchronization component is limited by the limiting component. When the transmission component utilizes axial rotation to convert into circumferential motion of the synchronization component, the synchronization component can be allowed to perform up and down reciprocating motion in the limiting component, so that the synchronization component can drive the cutting component to perform up and down reciprocating motion. When the conveying component conveys the power battery insulating film to the motion trajectory of the cutting component, the cutting component can cooperate with the conveying component to cut the insulating film, and through the current synchronization component and another identical synchronization component being interconnected, the other identical synchronization component can drive another identical cutting component to perform synchronous cutting on another identical insulating film, thereby finally achieving the effect of synchronous cutting of multiple insulating films.

[0042] The working principle of this embodiment is as follows: First, the synchronization mechanism 2 is connected to the PLC controller and the external power supply and started, and then the current synchronization transmission rod 233 is connected to another identical synchronization slide 231 until the number of connections matches the number of insulation films required for synchronization cutting, and then the servo motor 222 will drive the transmission turntable 223 to rotate, and the transmission turntable 223 will drive the synchronization guide rod 232 to perform circumferential motion together, and the synchronization guide rod 232 will drive the synchronization slide 231 to perform up and down reciprocating motion in the positioning track 213 during the circumferential motion, and then The rear synchronous transmission rod 233 will then drive another identical synchronous slide rod 231 to move synchronously. At this time, the electric conveying roller 251 will send the insulating film to the feeding tray 252. After the insulating film moves along the feeding tray 252 to the required cutting position, the transmission top plate 241 will drive the cutting plate 243 together under the drive of the synchronous slide rod 231. The cutting plate 243 will keep moving downward after contacting the insulating film and contact the front end of the feeding tray 252. At this time, the insulating film will be cut by the cutting plate 243 and the feeding tray 252.
