Description

Technical Field

[0001] This utility model belongs to the field of insulating film technology for new energy vehicle batteries, specifically an insulating film cutting and folding device. Background Technology

[0002] In existing technologies, the PI material insulating film used in the thin batteries of new energy vehicles is usually cut by die-cutting or cutting machine, and then bent by bending equipment.

[0003] The reason why two machines are needed instead of one machine to automatically complete the film cutting and folding processes is that cutting the insulating film from the roll requires maintaining a certain tension to ensure the accuracy of the cut insulating film. The difficulty in automating the cutting and folding process of insulating film lies in achieving continuous unwinding and feeding of the insulating film on the bending machine and maintaining a certain tension during the unwinding process. Utility Model Content

[0004] The purpose of this utility model is to provide an insulating film cutting and folding device that integrates a film cutting device and a film folding device. The film folding device enables continuous unwinding and feeding of the insulating film and maintains a certain tension during the unwinding process. This solves the difficulties in the automated cutting and folding of insulating films and improves the efficiency of the cutting and folding process.

[0005] The technical solution of this utility model is: an insulating film cutting and folding device, comprising: a film feeding device, a film cutting device, a film folding device, and a film pulling device.

[0006] The film feeding device, film cutting device, film folding device, and film pulling device are arranged in sequence.

[0007] The film feeding device includes an unwinding assembly and a tensioning assembly. The tensioning assembly includes a tensioning shaft and a torque motor. The tensioning shaft and the torque motor are connected. The insulating film extends from the unwinding assembly through the tensioning shaft and the film cutting device toward the film pulling device.

[0008] The film stretching device includes a servo motor, a transmission assembly, a cantilever, and a gripper. The transmission assembly is connected to the servo assembly, the cantilever is connected to the transmission assembly, and the gripper is connected to the cantilever.

[0009] The servo motor, transmission assembly, and cantilever are used to allow the grippers to pass through the film folding device to hold the insulating film away from the unwinding assembly, thereby moving the insulating film to or from the film folding device.

[0010] In a further embodiment, the insulating film cutting and folding equipment further includes a turnover box, which is disposed below the displacement component and can receive the finished insulating film removed from the folding device by the grippers.

[0011] In a further embodiment, the servo motor has an encoder, which can precisely control the number of rotations of the servo motor, thereby improving the length accuracy of the cut insulating film.

[0012] In a further embodiment, the cross-section of the cantilever is a triangular structure, and the height of the end of the cantilever closer to the gripper is less than the height of the end of the cantilever farther from the gripper. The triangular structure of the cantilever can improve the stability of the gripper in the cantilever state.

[0013] In a further embodiment, the film folding device includes a positioning stage and a film folding assembly.

[0014] The distance between the positioning stage and the folding assembly is greater than the width of the gripper, so that the gripper can pass through the folding device to hold the insulating film without interfering with the positioning stage and the folding assembly.

[0015] In a further embodiment, the film folding device further includes: a film folding frame, a pressing cylinder, a lifting plate, and a positioning plate.

[0016] The folding assembly includes: an upper folding mold, a lower folding mold, a folding cylinder, and a folding plate.

[0017] The pressing cylinder is installed on the film folding machine frame, the lifting plate is installed on the pressing cylinder, the positioning plate and the upper film folding mold are installed on the lifting plate, and the upper film folding mold is located on the side of the positioning plate.

[0018] The lower die and the folding cylinder are mounted on the folding machine frame. The lower die is positioned to the side of the positioning table, and the distance between the positioning table and the lower die is greater than the width of the gripper.

[0019] The upper and lower folding molds are correspondingly matched, the folding plate is installed on the folding cylinder, the folding plate is located on the side of the lower folding mold, and the folding cylinder is used to drive the folding plate to move towards the lower folding mold.

[0020] In a further embodiment, the upper folding mold includes a folding blade.

[0021] The lower die for folding is provided with a folding groove, the shape and position of which match the shape and position of the bottom end of the folding blade.

[0022] In a further embodiment, the upper and lower folding molds are provided with elongated holes.

[0023] The upper folding mold is installed on the lifting plate through an elongated hole, and the lower folding mold is installed on the folding machine frame through an elongated hole, which allows for convenient adjustment of the required bending position within a certain width range.

[0024] The beneficial effects of this utility model are as follows: By cooperating with the tension shaft and torque motor of the film feeding device, and the servo motor and gripper of the film pulling device, the insulating film can be pulled and moved with a certain tension, ensuring the length accuracy of the insulating film cut off when the film cutting device cuts the insulating film. By cooperating with the servo motor, transmission components and cantilever components of the film pulling device, the gripper can pass through the film folding device to hold the end of the insulating film away from the unwinding component, so that the insulating film can be continuously unwound and moved to the film folding device, and can also be moved out of the film folding device to complete the unloading. This allows the film feeding device, film cutting device, film folding device and film pulling device to cooperate to perform automated continuous film cutting, film folding and unloading, improving the processing efficiency of insulating film cutting and folding.

However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0034] This utility model discloses an insulating film cutting and folding equipment, which includes a frame and a control device such as a PLC or main unit. A film feeding device, a film cutting device, a film folding device, and a film pulling device are installed on the frame.

[0035] like Figure 1-3 The insulating film cutting and folding equipment shown includes: a film feeding device 1, a film cutting device, a film folding device 2, a film pulling device, and a turnover box.

[0036] The film feeding device 1, film cutting device, film folding device 2 and film pulling device are arranged in sequence, and the turnover box is located below the displacement component.

[0037] The film feeding device 1 includes an unwinding assembly 12 and a tensioning assembly 11. The unwinding assembly 12 includes an unwinding shaft and an unwinding motor. The unwinding shaft and the unwinding motor cooperate to output the insulating film. The tensioning assembly 11 includes a tensioning shaft 111 and a torque motor 112. The tensioning shaft 111 and the torque motor 112 are connected. The insulating film extends from the unwinding assembly 12 through the tensioning shaft 111 and the film cutting device toward the film pulling device.

[0038] The film stretching device includes: a servo motor, a transmission assembly, a cantilever, and grippers. The transmission assembly is connected to the servo assembly, the cantilever is connected to the transmission assembly, and the grippers are connected to the cantilever.

[0039] The servo motor, transmission assembly, and cantilever are used to move the gripper through the film folding device 2 to hold the end of the insulating film away from the unwinding assembly 12, thereby moving the insulating film to or from the film folding device 2.

[0040] The turnover box is located below the movement path of the gripper.

[0041] The servo motor has an encoder, which is used to connect to the control device.

[0042] like Figure 5 The cross-section of the cantilever shown is a triangular structure, and the height of the end of the cantilever closer to the gripper is less than the height of the end of the cantilever farther from the gripper.

[0043] like Figure 4 The film folding device 2 shown includes: a positioning stage 21 and a film folding assembly 22.

[0044] The distance between the positioning stage 21 and the folding assembly 22 is greater than the width of the gripper.

[0045] like Figure 4 The film folding device 2 shown also includes: a film folding frame, a pressing cylinder 23, a lifting plate 24, and a positioning plate 25.

[0046] The folding assembly 22 includes: an upper folding mold 221, a lower folding mold 222, a folding cylinder 224, and a folding plate 223.

[0047] The pressing cylinder 23 is installed on the film folding machine frame, the lifting plate 24 is installed on the pressing cylinder 23, the positioning plate 25 and the upper film folding mold 221 are installed on the lifting plate 24, the upper film folding mold 221 is located on the side of the positioning plate 25, wherein the positioning plate 25 is installed on the lifting plate 24 through an elastic mechanism, so that the positioning plate 25 and the positioning table 21 can position the insulating film when the upper film folding mold 221 and the lower film folding mold 222 are in a non-cooperative state.

[0048] The lower die 222 and the folding cylinder 224 are mounted on the folding machine frame. The lower die 222 is located on the side of the positioning table 21. The distance between the positioning table 21 and the lower die 222 is greater than the width of the gripper.

[0049] The upper folding mold 221 and the lower folding mold 222 are fitted together accordingly, such as... Figure 7 The folding plate 223 shown is installed on the folding cylinder 224. The folding plate 223 is located on the side of the lower folding mold 222. The folding cylinder 224 is used to drive the folding plate 223 to move towards the lower folding mold 222.

[0050] like Figure 7 The folding device 2 shown also includes a buffer, which is disposed on the side of the folding plate 223 away from the positioning stage 21.

The direction of the elongated hole is matched with the moving direction of the folding plate 223. It is used to adjust the distance between the two sets of upper folding molds 221 and lower folding molds 222, thereby adjusting the width of the bent insulating film.

[0054] In the above embodiments, the unwinding assembly 12 and the film cutting device are existing technologies and will not be limited here. The insulating film cutting and folding equipment is also equipped with a guide mechanism such as a guide rail mechanism and a guide shaft mechanism that cooperate with the pressing cylinder 23, the folding cylinder 224 and the transmission assembly. The transmission assembly can be a linear transmission mechanism such as a lead screw mechanism.

[0055] During operation, the grippers pass through the film folding device 2 to clamp the end of the insulating film. Then, the unwinding assembly 12, the tensioning assembly 11, and the film pulling device work together to keep the insulating film under certain tension and move it a predetermined length. Then, the film folding device 2 cuts the insulating film, and then the grippers continue to move the insulating film to a predetermined position on the positioning table 21.

[0056] Then, the pressing cylinder 23 drives the positioning plate 25 and the positioning table 21 to position the insulating film. Then, the pressing cylinder 23 continues to drive the upper folding mold 221 and the lower folding mold 222 to pre-fold the insulating film.

[0057] Then the folding cylinder 224 drives the folding plate 223 to move towards the positioning table 21, so that the insulating film continues to bend along the pre-bending direction to the predetermined angle.

[0058] Then the pressing cylinder 23 and the folding cylinder 224 are reset.

[0059] Finally, the grippers hold the end of the insulating film again. After the film pulling device moves the finished insulating film above the turnover box, the grippers separate from the finished insulating film, allowing the finished insulating film to fall into the turnover box.

[0060] Repeat the above steps to automate continuous film cutting, folding, and unloading.
