Description

Technical Field

[0001] This utility model is a copper clad laminate cutting mechanism, belonging to the field of copper clad laminate processing. Background Technology

[0002] Copper-clad laminate (CCL) blanking refers to the process of cutting CCLs into specific sizes or shapes according to the circuit board design requirements. It is the first critical step in PCB manufacturing. Laser cutting is a commonly used method for CCL blanking. The laser cutting head beam moves along two parallel guide rails driven by the drive system. Both ends of the laser cutting head beam are equipped with upper rollers that roll in contact with the guide rails. During repeated movement, the weight of the laser cutting head beam and other components acts on the upper surface of the guide rails through the upper rollers, causing the upper surface of the guide rails to deform due to pressure. To avoid the influence of guide rail deformation on the movement trajectory of the laser cutting head, deformed guide rails need to be replaced periodically, resulting in high component maintenance costs. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a copper clad laminate cutting mechanism to solve the problems mentioned in the background art. This utility model enables the individual replacement of easily worn parts of the guide rail, reducing the maintenance cost of parts.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a copper-clad laminate cutting mechanism, comprising a laser cutting head beam rail, with vertical rods installed at both ends of the laser cutting head beam rail, a carrier plate installed at the lower end of each of the two vertical rods, a support on the lower side of each of the two carrier plates, a horizontally arranged rack installed on the outer side of one support, and a driving component for moving the carrier plate, which cooperates with the rack, installed on one carrier plate. A guide rail is installed on the upper surface of the support by multiple screws. Two symmetrically arranged upper rollers are rotatably mounted on the upper surface of the carrier plate. Side rollers, which are rotatably connected to the carrier plate, are provided on both sides of the upper rollers. The side rollers roll in contact with the sides of the rack. The upper surface of the guide rail is recessed downward to form a strip groove, and multiple thin plates connected end to end are inserted into the strip groove. The upper rollers roll in contact with the thin plates.

[0005] Furthermore, the bottom of the strip groove is recessed downwards with multiple equally spaced circular grooves, and a magnetic block that attracts the guide rail is inserted in the circular groove, and the magnetic block attracts the thin plate.

[0006] Furthermore, the driving component includes a frame, on which the frame is mounted on a carrier plate. A large synchronous pulley is rotatably mounted at the lower part of the frame, and a small synchronous pulley is rotatably mounted at the upper part of the frame. The large synchronous pulley is connected to the small synchronous belt via a synchronous belt. A servo motor for driving the small synchronous pulley to rotate is mounted on the side of the frame away from the support leg. A gear meshing with the rack is provided on the rack, and the gear is connected to the large synchronous pulley via a transmission shaft.

[0007] Furthermore, both ends of the support are equipped with limiting plates, and the outermost thin plate is in contact with the limiting plate.

[0008] Furthermore, a bracket for supporting the copper-clad laminate is provided between the two brackets. Two symmetrically arranged bottom beams are provided on the lower side of the bracket. The two ends of the bottom beams are respectively connected to the two brackets. Two support legs are symmetrically installed at the bottom of the two brackets.

[0009] Furthermore, a drawer box for collecting debris is provided on the underside of the bottom beam. Two right-angle irons for supporting the drawer box are provided at the bottom of the drawer box. The right-angle irons are connected to the corresponding support legs. A handle is installed in the middle of one side of the drawer box.

[0010] Furthermore, the support leg is a hollow structure, and a nut is installed at the lower end of the support leg. An adjusting foot is connected to the internal thread of the nut.

[0011] The beneficial effects of this utility model are:

[0012] 1. A groove is formed on the upper surface of the guide rail, and multiple thin plates are inserted into the groove, with the upper roller only contacting the thin plates. When a thin plate deforms due to pressure, a single thin plate can be replaced, which reduces maintenance costs compared to replacing the entire guide rail in the traditional way.

[0013] 2. Using magnetic blocks to confine multiple thin plates within the strip groove improves the stability of the thin plates. When replacing deformed thin plates, the carrier plate is moved to an area away from the damaged thin plates, thus facilitating the replacement of thin plates one by one without disassembling other components.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a copper-clad laminate cutting mechanism, including a laser cutting head crossbeam rail 1, with vertical rods 17 installed at both ends of the laser cutting head crossbeam rail 1, and a carrier plate 13 installed at the lower end of each of the two vertical rods 17. Each carrier plate 13 has a support 7 on its lower side, and a bracket 3 for supporting the copper-clad laminate is provided between the two supports 7. Two symmetrically arranged bottom beams 22 are provided on the lower side of the bracket 3, with both ends of the bottom beams 22 connected to the two supports 7 respectively. Two symmetrically installed legs 9 are mounted on the bottom of the two supports 7. The legs 9 are hollow structures, and the lower ends of the legs 9 are fitted with… The laser cutting head crossbeam rail 1 is equipped with a nut, and the nut is internally threaded with an adjusting foot 10. The adjusting foot 10 and the nut cooperate to facilitate the adjustment of the level of the laser cutting head crossbeam rail 1. A drawer box 4 for collecting debris is provided on the lower side of the bottom beam 22. Two right-angle irons 8 for supporting the drawer box 4 are provided at the bottom of the drawer box 4. The right-angle irons 8 are connected to the corresponding support legs 9. A handle 5 is installed in the middle of one side of the drawer box 4. When the laser generated by the laser cutting head cuts the copper-clad board on the bracket 3, the debris generated falls into the drawer box 4 through the bracket 3, realizing the centralized collection of debris.

[0022] See Figure 1 and Figure 2A horizontally arranged rack 11 is mounted on the outer side of a support 7. A frame 14 is mounted on a carrier plate 13. A large synchronous pulley 19 is rotatably mounted in the lower part of the frame 14, and a small synchronous pulley 21 is rotatably mounted in the upper part of the frame 14. The large synchronous pulley 19 is connected to the small synchronous pulley 21 through a synchronous belt 20. A servo motor 15 for driving the rotation of the small synchronous pulley 21 is mounted on the side of the frame 14 away from the support leg 9. A gear 18 is provided on the rack 11 and meshes with the rack 11. The gear 18 is connected to the large synchronous pulley 19 through a transmission shaft. When the servo motor 15 is working, it drives the gear 18 to move along the rack 11 through the transmission of the large synchronous pulley 19, the small synchronous pulley 21 and the synchronous belt 20. Thus, the laser cutting head crossbeam rail 1, the carrier plate 13 and other components move along the guide rail 6. The laser cutting head crossbeam rail 1 is equipped with a servo drive system for driving the laser cutting head. The structure and working principle of the servo drive system have been fully disclosed in the prior art, so they will not be described again.

[0023] See Figure 1 and Figure 2 The upper surface of the support 7 is equipped with guide rails 6 by multiple screws. The upper surface of the carrier plate 13 is rotatably mounted with two symmetrically arranged upper rollers 16. Both sides of the upper rollers 16 are provided with side rollers 12 that are rotatably connected to the carrier plate 13. The side rollers 12 are in rolling contact with the side of the rack 11. The side rollers 12 and the upper rollers 16 cooperate with each other to reduce movement resistance.

[0024] See Figures 1-4 The upper surface of the guide rail 6 is recessed downwards to form a strip groove 25. Multiple thin plates 2, connected end-to-end, are inserted into the strip groove 25. The upper roller 16 rolls in contact with the thin plates 2. Limiting plates 23 are installed at both ends of the support 7. One end of the outermost thin plate 2 contacts the limiting plate 23. The limiting plate 23 and the strip groove 25 cooperate to restrict the position of the thin plate 2. The upper surface of the guide rail 6 has a strip groove 25, within which multiple thin plates 2, connected end-to-end, are inserted. The upper roller 16 only contacts the thin plates 2. When a thin plate 2 deforms due to pressure, a single thin plate 2 can be replaced, reducing maintenance costs compared to replacing the entire guide rail 6 in the traditional method.

[0025] See Figures 1-4 Multiple equally spaced circular grooves 24 are recessed downward at the bottom of the strip groove 25. Magnet blocks 26 that attract the guide rail 6 are inserted in the circular grooves 24. The magnet blocks 26 attract the thin plate 2. The magnet blocks 26 are used to restrict multiple thin plates 2 within the strip groove 25, thereby improving the stability of the thin plate 2. When replacing a deformed thin plate 2, the carrier plate 13 is moved to an area away from the damaged thin plate 2, thereby facilitating the replacement of the thin plates 2 one by one without disassembling other parts.
