Description

Technical Field

[0001] The utility model belongs to the technical field of copper foil processing equipment, and particularly relates to an automatic copper foil feeding mechanism for a copper foil wrapping machine. Background Art

[0002] A copper foil wrapping machine refers to a machine used to automatically wrap electronic components such as circuit boards and parts in copper foil paper. This kind of machine is usually used to prevent short circuits and corrosion between components, protect the components from the external environment, and at the same time improve the reliability of the components and prevent damage. During the preparation of wire materials such as copper wires, it is necessary to perform copper foil wrapping treatment on the wire materials to increase the transmission performance of the wire materials. During the copper foil processing of the copper foil wrapping machine, an automatic feeding mechanism is often used.

[0003] In the existing copper foil wrapping machine, when the feeding reel feeds the copper foil, since it is impossible to ensure that the copper foil is in a taut state, and the copper foil is in a slightly bent state due to its own toughness, the copper foil is prone to chaos during transportation. For this reason, we provide an automatic copper foil feeding mechanism for a copper foil wrapping machine to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic copper foil feeding mechanism for a copper foil wrapping machine. Through the cooperative setting of a stirring component and a linkage component, the problem that the copper foil is prone to chaos during transportation when the feeding reel feeds the copper foil in the existing copper foil wrapping machine is solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an automatic copper foil feeding mechanism for a copper foil wrapping machine, including a support plate installed on the copper foil wrapping machine. Two symmetrically arranged positioning plates are fixedly connected to the side end face of the support plate. A conveying component is arranged between the two positioning plates. A linkage component is arranged on the conveying component. A connecting shaft is arranged on the linkage component. The connecting shaft is rotatably connected inside the support plate. A feeding reel is fixedly connected to the connecting shaft.

[0007] A stabilizing component is arranged inside the support plate, and the copper foil is stably wound on the feeding reel through the stabilizing component.

[0008] The utility model is further arranged such that the conveying component includes a motor and a rotating shaft. The motor is fixedly installed on the positioning plate. The output end of the motor is fixedly connected to a driving shaft. A driving gear and a first conveying roller are fixedly connected to the driving shaft. The driving gear is located outside the first conveying roller.

[0009] The present utility model is further configured such that the rotating shaft is rotatably connected between two positioning plates. A driven gear and a second conveying roller are fixedly connected to the rotating shaft. The driving gear meshes with the driven gear, and the first conveying roller and the second conveying roller are arranged symmetrically up and down.

[0010] The present utility model is further configured such that the linkage assembly includes a first pulley, a second pulley, and a transmission belt. The first pulley is fixedly connected to the driving shaft and is located outside the driving gear. The second pulley is fixedly connected to the connecting shaft and is located outside the unwinding roller. The first pulley and the second pulley are driven by the transmission belt.

[0011] The present utility model is further configured such that the stabilizing assembly includes a cam and an L-shaped rod. The cam is fixedly installed on the connecting shaft, and the position of the cam is between the second pulley and the unwinding roller. The L-shaped rod is fixedly installed on the inner side surface of the support plate and is located below the unwinding roller.

[0012] The present utility model is further configured such that a lifting plate is slidably connected to the surface of the L-shaped rod, and the side end surface of the lifting plate is slidably connected to the inner side surface of the support plate.

[0013] The present utility model is further configured such that a spring is fixedly connected to the lower end surface of the lifting plate, and the end of the spring away from the lifting plate is fixedly connected to the inner bottom of the support plate. The position of the spring is outside the L-shaped rod.

[0014] The present utility model is further configured such that the shape of the support plate is U-shaped, and the shape of the positioning plate is L-shaped.

[0015] The present utility model has the following beneficial effects:

[0016] 1. In the present utility model, the motor in the conveying assembly drives the first conveying roller on the driving shaft to rotate, and then the driving gear on the driving shaft meshes with the driven gear on the rotating shaft, so that the second conveying roller on the rotating shaft rotates, causing the first conveying roller and the second conveying roller to rotate in opposite directions. Then, through the linkage assembly, the unwinding roller on the connecting shaft rotates synchronously with the first conveying roller, effectively keeping the copper foil on the unwinding roller straight and taut during conveying, ensuring the smooth conveying of the copper foil and avoiding chaos, and improving the working efficiency and stability of the automatic feeding mechanism.

[0017] 2. In the present utility model, when the connecting shaft rotates, the connecting shaft will synchronously drive the cam to rotate. When the cam rotates a specified angle, it will press down the lifting plate. The lifting plate will move downward under the limit of the L-shaped rod, and at the same time, the lifting plate will compress the spring. When the cam no longer presses the lifting plate, the lifting plate will return to its original position under the elastic force of the spring. By continuously pressing the copper foil on the unwinding roller with the pressing roller on the lifting plate, the smooth conveying of the copper foil and the avoidance of chaos are effectively achieved.

[0018] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Specific Embodiment

[0027] Please refer to Figures 1-5, the utility model relates to an automatic copper foil feeding mechanism for a copper foil wrapping machine, which includes a support plate 1 installed on the copper foil wrapping machine. Two symmetrically arranged positioning plates 2 are fixedly connected to the side end face of the support plate 1. A conveying assembly is arranged between the two positioning plates 2. A linkage assembly is arranged on the conveying assembly. A connecting shaft 3 is arranged on the linkage assembly. The connecting shaft 3 is rotatably connected inside the support plate 1. A feeding roller 4 is fixedly connected to the connecting shaft 3. The conveying assembly includes a motor 5 and a rotating shaft 6. The motor 5 is fixedly installed on the positioning plate 2. The output end of the motor 5 is fixedly connected to a driving shaft 7. A driving gear 8 and a first conveying roller 9 are fixedly connected to the driving shaft 7. The driving gear 8 is located outside the first conveying roller 9. The rotating shaft 6 is rotatably connected between the two positioning plates 2. A driven gear 10 and a second conveying roller 11 are fixedly connected to the rotating shaft 6. The driving gear 8 meshes with the driven gear 10. The first conveying roller 9 and the second conveying roller 11 are arranged symmetrically up and down. The support plate 1 is U-shaped, and the positioning plate 2 is L-shaped.

[0028] Specifically: The first conveying roller 9 and the second conveying roller 11 rotate in opposite directions. When the first conveying roller 9 and the second conveying roller 11 rotate, it is convenient to pull out the copper foil on the feeding roller 4. The driving source of the motor 5 can be installed on the positioning plate 2, as long as the normal operation of the motor 5 is ensured. The U-shaped support plate 1 facilitates the installation of the feeding roller 4. At the same time, the L-shaped positioning plate 2 makes the connection between the first conveying roller 9 and the second conveying roller 11 at the same horizontal plane as the feeding roller 4, which is convenient for realizing the feeding of the copper foil. Specific embodiment

[0029] Please refer to Figures 1-5 , on the basis of the first specific embodiment, the linkage assembly includes a first pulley 12, a second pulley 13 and a transmission belt 14. The first pulley 12 is fixedly connected to the driving shaft 7 and is located outside the driving gear 8. The second pulley 13 is fixedly connected to the connecting shaft 3 and is located outside the feeding roller 4. The first pulley 12 and the second pulley 13 are driven by the transmission belt 14.

[0030] Specifically: When the driving shaft 7 rotates, the driving shaft 7 will drive the first pulley 12 to rotate. When the first pulley 12 rotates, it will drive the second pulley 13 to rotate through the transmission belt 14. When the second pulley 13 rotates, it will drive the feeding roller 4 to rotate through the connecting shaft 3. At this time, the rotating direction of the feeding roller 4 is the same as that of the first conveying roller 9, ensuring that the feeding roller 4 will not be loose when feeding the copper foil. Specific embodiment

[0031] Please refer to Figures 1-5, on the basis of Specific Embodiment 1 and Specific Embodiment 2, a stabilizing component is provided inside the support plate 1. Through the stabilizing component, the copper foil is stably wound on the unwinding roller 4. The stabilizing component includes a cam 15 and an L-shaped rod 16. The cam 15 is fixedly installed on the connecting shaft 3. The position of the cam 15 is between the pulley 2 13 and the unwinding roller 4. The L-shaped rod 16 is fixedly installed on the inner side surface of the support plate 1 and is below the unwinding roller 4. A lifting plate 17 is slidably connected to the surface of the L-shaped rod 16. The side end surface of the lifting plate 17 is slidably connected to the inner side surface of the support plate 1. A fixed shaft 18 is fixedly connected to the side end surface of the lifting plate 17. An extrusion roller 19 is fixedly connected to the fixed shaft 18. A spring 20 is fixedly connected to the lower end surface of the lifting plate 17. The end of the spring 20 away from the lifting plate 17 is fixedly connected to the inner bottom of the support plate 1. The position of the spring 20 is outside the L-shaped rod 16.

[0032] Specifically: When the connecting shaft 3 rotates, the connecting shaft 3 will synchronously drive the cam 15 to rotate. When the cam 15 rotates a specified angle, it will press down the lifting plate 17. The lifting plate 17 will be limited by the L-shaped rod 16 and move downward. At the same time, the lifting plate 17 will compress the spring 20. When the cam 15 no longer presses the lifting plate 17, the lifting plate 17 will return to its original position under the elastic force of the spring 20. Among them, the pulley 1 12 and the pulley 2 13 are not on the same horizontal plane, and at the same time, the frictional force between the transmission belt 14 and the pulley 1 12 and the pulley 2 13 is relatively large, ensuring the normal rotation between the pulley 1 12 and the pulley 2 13.

[0033] Working principle:

[0034] During use, the motor 5 drives the drive shaft 7 to rotate. The drive shaft 7 drives the conveying roller 1 9 to rotate. At the same time, the drive shaft 7 also drives the driving gear 8 to rotate. Through the meshing of the driving gear 8 and the driven gear 10, the driven gear 10 drives the conveying roller 2 11 to rotate through the rotating shaft 6. At this time, the conveying roller 1 9 and the conveying roller 2 11 rotate in opposite directions. When the drive shaft 7 rotates, it will synchronously drive the pulley 1 12 to rotate. When the pulley 1 12 rotates, it will drive the pulley 2 13 to rotate through the transmission belt 14. When the pulley 2 13 rotates, it will drive the unwinding roller 4 to rotate through the connecting shaft 3. At this time, the upper unwinding roller 4 and the conveying roller 1 9 rotate synchronously, effectively making the copper foil on the unwinding roller 4 always in a straight and taut state during conveying, ensuring the smooth conveying of the copper foil and avoiding chaos, and improving the working efficiency and stability of the automatic feeding mechanism;

[0035] When the connecting shaft 3 rotates, the connecting shaft 3 will synchronously drive the cam 15 to rotate. When the cam 15 rotates a specified angle, it will press down the lifting plate 17. The lifting plate 17 will be limited by the L-shaped rod 16 and move downward. At the same time, the lifting plate 17 will squeeze the spring 20. When the cam 15 no longer presses the lifting plate 17, the lifting plate 17 will return to its original position under the elastic force of the spring 20. The copper foil on the feeding roller 4 is continuously squeezed by the squeezing roller 19 on the lifting plate 17, effectively realizing the smooth conveying of the copper foil and avoiding chaos.
