Description

Technical Field

[0001] This utility model relates to the field of epoxy resin board processing technology, specifically a cutting device for epoxy resin boards. Background Technology

[0002] Epoxy resin circuit boards have a wide range of applications, and their production technology is constantly innovating. With the increasing use of surface-mount electronic components, circuit boards can be manufactured to be increasingly compact. Circuit boards miniaturize and visualize circuits, playing a crucial role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards are also known as printed circuit boards or printed circuit boards. After production, epoxy resin circuit boards need to be cut and separated. Currently, circuit board separation is usually done manually using a cutting knife along the cutting lines. This method is time-consuming, labor-intensive, and inefficient. Furthermore, manual feeding poses a safety hazard as workers may cut their hands. Summary of the Invention

[0020] Please see Figure 1 - Figure 4 A cutting device for epoxy resin boards includes a base 1. A first screw 11 is rotatably connected to the top of the base 1. A movable plate 12 is threadedly connected to the outer wall of the first screw 11. The movable plate 12 is slidably connected to the top of the base 1. A second screw 16 is rotatably connected to the top of the movable plate 12. Clamping blocks 13 are threadedly connected to both sides of the outer wall of the second screw 16. Both clamping blocks 13 are slidably connected to the top of the movable plate 12. Electric cylinders 14 are fixedly connected to the top of both clamping blocks 13. Clamping plates 15 are fixedly connected to the output ends of both electric cylinders 14. A top plate 17 is fixedly connected to the top of the base 1. A cutting blade 18 is installed below the top plate 17. A feeding mechanism 2 is provided inside the base 1. The feeding mechanism 2 is used to feed epoxy resin boards.

[0021] The specific implementation process is as follows: The feeding mechanism 2 can transport the epoxy resin board between the two clamping blocks 13. Then, the output end of the electric cylinder 14 moves downward. Then, the clamping plates 15 on both sides of the epoxy resin board will squeeze the epoxy resin board. After the two clamping plates 15 have squeezed the epoxy resin board, as the screw 11 rotates, the moving plate 12 will gradually move towards the direction of the cutting blade 18. Then, the cutting blade 18 will complete the cutting of the epoxy resin board. Example 2

[0022] Please see Figure 1 - Figure 4 A cutting device for epoxy resin boards includes a feeding mechanism 2 comprising a cam 21 and a support rod 22. Both the cam 21 and the support rod 22 are rotatably connected inside a base 1. A disc 23 is rotatably connected to the outside of the support rod 22. The outer wall of the disc 23 is slidably connected to the outer wall of the cam 21. A connecting block 25 is slidably connected above the support rod 22. A slider 24 is fixedly connected above the connecting block 25. The slider 24 is slidably connected to the top of the base 1. A spring 26 is rotatably connected to one side of the support rod 22. The end of the spring 26 away from the support rod 22 is rotatably connected inside the base 1. Two feeding rollers 27 are rotatably connected above the base 1. A pulley 29 is drivingly connected between the cam 21 and one feeding roller 27. A baffle 28 is fixedly connected above the base 1.

[0023] The specific implementation process is as follows: If it is necessary to feed the epoxy resin board stacked on the base 1, the operator can operate the cam 21 and make it rotate. During the rotation of the cam 21, the cam 21 will squeeze the disc 23. After the disc 23 is squeezed, the support rod 22 will rotate. At this time, the spring 26 will be pulled and stretched. As the cam 21 rotates, when the cam 21 loses the squeezing of the disc 23, the spring 26, which is in a stretched state, will rebound. As the spring 26 rebounds, the slider 24 will slide above the base 1. During this process, the protrusion above the slider 24 will squeeze the lowest epoxy resin board and place it between the two feeding rollers 27. Then the feeding rollers 27 will complete the feeding of the epoxy resin board. When the slider 24 completes the feeding of the epoxy resin board, it can be reset before the stacked epoxy resin board falls to the surface of the base 1.

[0024] The usage method and working principle of this utility model are as follows: To load epoxy resin boards stacked on top of base 1, the operator can manipulate cam 21 to rotate. During the rotation of cam 21, cam 21 will compress disk 23. After disk 23 is compressed, support rod 22 will rotate, at which time spring 26 will be pulled and stretched. As cam 21 rotates, when cam 21 loses its compression on disk 23, spring 26, which is in a stretched state, will rebound. With the rebound of spring 26, slider 24 will slide above base 1. During this process, the protrusion on top of slider 24 will compress the lowest epoxy resin board. The epoxy resin board is fed between two feeding rollers 27. The feeding rollers 27 then complete the feeding of the epoxy resin board. When the slider 24 completes the feeding of the epoxy resin board, it can be reset before the accumulated epoxy resin board falls onto the surface of the base 1. After the feeding mechanism 2 completes the feeding of the epoxy resin board, the output end of the electric cylinder 14 moves downward. Then the clamping plates 15 on both sides of the epoxy resin board will squeeze the epoxy resin board. After the two clamping plates 15 have squeezed the epoxy resin board, as the screw 11 rotates, the moving plate 12 will gradually move towards the direction of the cutting blade 18. Then the cutting blade 18 will complete the cutting of the epoxy resin board.
