Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper foil roll cutting technology, specifically to a copper foil roll cutting device that can be precisely positioned. Background Technology
[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board. As a conductor in the PCB, it easily adheres to the insulating layer, accepts the printed protective layer, and forms circuit patterns after etching. As an important raw material, copper foil is widely used in the machinery industry. Generally, copper foil is processed into rolls for production line processing. In actual use, copper foil rolls are unwound according to the required length and cut into specified lengths for later use, which is applied to a copper foil roll cutting device.
[0003] Existing copper foil roll slitting equipment typically uses a conveyor to transfer the unwound copper foil to the designated slitting position. However, due to the lack of necessary positioning during the transfer process, the copper foil roll is prone to uncontrollable curling due to prolonged winding, making it impossible to measure the unwound length. Furthermore, the conveyor may deviate during the transfer process, causing the subsequent slitting line to be tilted at a certain angle to the center line of the copper foil. This results in the cut end face of the copper foil roll being tilted, inconsistent with the desired roll shape, requiring further slitting at the tilted end face and causing waste of some roll material.
[0004] Therefore, it is necessary to invent a copper foil roll cutting device that can be precisely positioned to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a copper foil roll slitting device with precise positioning. This solves the problems in existing technologies where, due to the lack of necessary positioning, copper foil rolls are prone to uncontrollable curling during actual transport, making it impossible to measure the unwinding length. Furthermore, during transport by the conveying components, offsets can easily occur, causing the subsequent slitting line to tilt at a certain angle to the center line of the copper foil. This results in the cut copper foil roll having an inclined end face, inconsistent with the desired roll shape, necessitating further slitting at the inclined end face and wasting some roll material.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A copper foil roll cutting device with precise positioning includes a base plate, a platform inserted into the right end of the base plate, and a conveying assembly rotatably disposed within the base plate to transfer copper foil from left to right. A cutter for cutting copper foil is longitudinally slidably disposed above the platform. A U-shaped fixing frame is installed between the two sides of the top surface of the base plate. Two L-shaped clamps are slidably disposed between the two sides of the U-shaped fixing frame in a direction that moves towards or away from the center of the conveying assembly. A side clamp plate that can abut against the side of the copper foil is installed at the end of the vertical part of the L-shaped clamp. Multiple elastic components are disposed at the bottom end of the horizontal part of the L-shaped clamp. A mounting frame is mounted on the bottom end of the multiple elastic components. Multiple pressure guide rollers that can rotate and abut against the top surface of the copper foil are rotatably disposed within the mounting frame.
[0008] In a preferred embodiment of this utility model, the elastic component includes a telescopic frame and a spring sleeved on the telescopic frame. The top end of the telescopic frame is connected to the bottom end of the horizontal part of the L-shaped card holder, and the bottom end of the telescopic frame is connected to the top end of the mounting frame.
[0009] As a preferred embodiment of this utility model, a driving component is detachably installed at the center of the middle part of the U-shaped fixing frame via a placement seat. Both output ends of the driving component are equipped with screws, and the threads of the two screws are in opposite directions. A guide block is installed at the center of the top surface of the horizontal part of the L-shaped card holder. A slip ring is installed at the top of the guide block via a connecting post, and the slip ring is threaded onto the screw.
[0010] As a preferred embodiment of this utility model, the U-shaped fixing frame has guide grooves on both sides of the middle part for the guide block to slide towards or away from the center of the conveying component.
[0011] As a preferred embodiment of this utility model, a scale element is provided at the top of the middle part of the U-shaped fixing frame, which is adapted to one of the guide grooves.
[0012] As a preferred embodiment of this utility model, a U-shaped support is installed on the top surface of the platform near the bottom plate, a lifting component is installed inside the U-shaped support, a fixed plate is installed at the bottom end of the lifting component, and the cutter is detachably installed at the bottom end of the fixed plate.
[0013] In a preferred embodiment of this utility model, the bottom end of the vertical part of the L-shaped card holder is flush with the bottom end of the side clamp, and the bottom end of the side clamp is in contact with the outer peripheral surface of the conveying assembly.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] In this invention, during the process of the conveying component transferring the copper foil roll from left to right to the cutting position, two L-shaped clamps are driven to slide synchronously towards the center of the conveying component. This ensures that when the two side clamps abut against the sides of the copper foil roll, the copper foil roll is positioned at the center of the conveying component. Furthermore, the side clamps limit the movement of the copper foil roll, preventing unnecessary deviation during the transfer process. During synchronous transfer, the elastic components limit the movement of multiple pressure guide rollers, causing them to abut against the top surface of the copper foil roll simultaneously. Without affecting the transfer, the multiple pressure guide rollers apply anti-bending pressure to both sides of the top surface of the copper foil roll. Finally, the side clamps prevent the copper foil roll from shifting during the transfer process, and the pressure guide rollers simultaneously prevent the copper foil roll from bending. This allows for precise positioning of the copper foil roll's transfer direction and cutting position, facilitating subsequent cutting. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.
[0022] This utility model provides, for example Figure 1-3The copper foil roll cutting device shown includes a base plate 1, a platform 2 inserted into the right end of the base plate 1, and a conveying assembly 3 rotatably disposed within the base plate 1 to transfer copper foil from left to right. A cutter 7 for cutting copper foil is longitudinally slidably disposed above the platform 2. A U-shaped fixing frame 8 is installed between the two sides of the top surface of the base plate 1. Two L-shaped clamps 13 are slidably disposed between the two sides of the U-shaped fixing frame 8 in a direction that moves towards or away from the center of the conveying assembly 3. The vertical ends of the L-shaped clamps 13 are fitted with side clamps 14 that can abut against the sides of the copper foil. The L-shaped clamps 13 are horizontal. The bottom of the part is provided with multiple elastic components, and the bottom of the multiple elastic components are jointly mounted on the mounting frame 16. Multiple pressing guide rollers 17 that can rotate and abut against the top surface of the copper foil are rotatably installed inside the mounting frame 16. The elastic components include a telescopic frame 15 and a spring 18 sleeved on the telescopic frame 15. The top of the telescopic frame 15 is connected to the bottom of the horizontal part of the L-shaped card holder 13, and the bottom of the telescopic frame 15 is connected to the top of the mounting frame 16. Under the longitudinal elastic limit of the elastic components, the pressing guide rollers 17 perform anti-bending pressing on both sides of the top surface of the copper foil roll without affecting the transmission.
[0023] A drive unit 10 is detachably mounted on the center of the middle part of the U-shaped fixing frame 8 via a placement seat 9. Both output ends of the drive unit 10 are equipped with screws 11, and the threads of the two screws 11 are opposite. A guide block 19 is mounted on the center of the top surface of the horizontal part of the L-shaped card holder 13. A slip ring 21 is mounted on the top of the guide block 19 via a connecting post 20. The slip ring 21 is threaded onto the screw 11. Guide grooves 12 are provided on both sides of the middle part of the U-shaped fixing frame 8 to allow the guide blocks 19 to slide towards or away from the center of the conveying component 3. The drive unit 10 drives the two screws 11 to rotate synchronously, thereby driving the two slip rings 21 to slide along the corresponding screws 11 towards or away from the center of the conveying component 3. During the process, the guide blocks 19 slide along the guide grooves 12, limiting the sliding direction of the slip rings 21 and the sliding direction of the L-shaped card holder 13.
[0024] A scale element 22 is provided at the top of the middle part of the U-shaped fixing bracket 8, which is adapted to one of the guide grooves 12. The sliding distance of the guide block 19 along the guide groove 12 can be intuitively obtained by reading the scale element 22.
[0025] A U-shaped support frame 4 is installed on the top surface of the platform 2 near the bottom plate 1. A lifting component 5 is installed inside the U-shaped support frame 4. A fixing plate 6 is installed at the bottom end of the lifting component 5. The cutter 7 is detachably installed at the bottom end of the fixing plate 6. The bottom end of the vertical part of the L-shaped bracket 13 is flush with the bottom end of the side clamp 14, and the bottom end of the side clamp 14 contacts the outer peripheral surface of the conveying component 3. The lifting component 5 moves vertically to change the longitudinal position of the cutter 7, thereby completing the switching of the cutter 7 from the stationary position to the cutting position.
[0026] In this invention, during the process of the conveying component 3 transferring the copper foil roll from left to right to the cutting position, two L-shaped clamps 13 are driven to slide synchronously towards the center of the conveying component 3. This ensures that when the two side clamps 14 abut against the sides of the copper foil roll, the copper foil roll is at the center of the conveying component 3. Furthermore, the side clamps 14 limit the movement of the copper foil roll, preventing unnecessary deviation during the transfer process. During synchronous transfer, the elastic components limit the movement of multiple pressing guide rollers 17, causing them to abut against the top surface of the copper foil roll simultaneously. Without affecting the transfer, the multiple pressing guide rollers 17 apply anti-bending pressure to both sides of the top surface of the copper foil roll. Finally, the side clamps 14 prevent the copper foil roll from shifting during the transfer process, and the pressing guide rollers 17 simultaneously prevent the copper foil roll from bending during the transfer process. This achieves precise positioning of the copper foil roll's transfer direction and cutting position, facilitating subsequent cutting.
[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
