Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine structure technology, and in particular to a circuit board laser cutting machine. Background Technology

[0002] A circuit board laser cutting machine is a device that uses laser technology to cut circuit boards, featuring high precision, high efficiency, and non-contact cutting. Its working principle involves focusing a high-energy laser beam onto the surface of the circuit board, causing the material to reach its melting or boiling point. High-pressure gas, coaxial with the laser beam, then blows away the molten or vaporized material, creating a kerf and achieving the cutting purpose. A search revealed that patent announcement number CN210147260U discloses a laser cutting machine for circuit boards, including a frame, a conveyor group for conveying flexible circuit boards, and a laser cutting group mounted on the frame. The conveyor group is installed below the laser cutting group on the frame. The conveyor group includes a feeding roller, a feeding roller, and a conveyor track arranged sequentially along the conveying direction. A working position is provided at the output end of the conveyor track, and the laser cutting group can cut the flexible circuit board at the working position into shape. This laser cutting machine uses the feeding roller to clamp and feed the flexible circuit board, ensuring the conveying power of the entire flexible circuit board. The conveyor track restricts the movement direction of the flexible circuit board output by the feeding roller, which can also improve the stability of the flexible circuit board movement and prevent the flexible circuit board from swaying. In addition, the working position on the conveyor track cooperates with the laser cutting group to ensure the cutting quality of the entire flexible circuit board. This cutting machine has a simple structure, stable conveying, and is suitable for conveying and processing flexible circuit boards.

[0003] However, existing laser cutting machines are not stable during movement and are prone to deviation, which affects the cutting effect. Therefore, there is an urgent need in the market for a circuit board laser cutting machine to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board laser cutting machine to solve the problem mentioned in the background art that the existing laser cutting machine has poor stability and is prone to deviation during movement, which affects the cutting effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-4 This utility model provides an embodiment of a circuit board laser cutting machine, comprising a base 1, mounting brackets 2 on both sides of the base 1, a lead screw 3 inside the mounting bracket 2, a movable seat 5 outside the lead screw 3, positioning rods 6 on both sides of the lead screw 3, a sliding seat 9 outside the positioning rods 6, a mounting box 10 on one side of the sliding seat 9 and the movable seat 5, a laser cutting seat 11 at the lower end of the mounting box 10, a blower pipe 23 on one side of the laser cutting seat 11, a lead screw 12 inside the base 1, a movable seat 14 outside the lead screw 12, positioning rods 15 on both sides of the lead screw 12, a sliding seat 24 outside the positioning rods 15, mounting seats 16 at both ends of the outer wall of the base 1, and a support seat 18 above the movable seat 14 and the sliding seat 24. A placement box 19 is provided at the upper end of the support base 18. A placement seat 1901 is provided inside the placement box 19. A feeding seat 1902 is provided at both ends of the placement seat 1901. An installation end 1903 is provided on both sides of the upper end of the placement box 19. A cylinder 20 is installed on one side of the installation end 1903. The installation box 10 can be moved by the moving seat 11 and the sliding seat 19, which in turn can move the laser cutting seat 11. The support base 18 can be moved by the moving seat 24 and the sliding seat 24, which allows the placed circuit board to move. This allows the laser cutting seat 11 to easily laser cut the circuit board. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the working principle and process of how to laser cut the circuit board, it will not be described in detail in this patent.

[0018] See Figure 1 and Figure 4 One side of the outer wall of the mounting frame 2 is equipped with a lead screw motor 4 corresponding to the lead screw 3. Two positioning rods 6 are provided, and the two positioning rods 6 are symmetrical about the vertical center line of the lead screw 3. Mounting seats 7 are provided at both ends of the outer wall of the mounting frame 2. The two ends of the positioning rods 6 are located inside the mounting seats 7 respectively. The positioning rods 6 and the mounting seats 7 are fixedly connected by fastening screws 8. This arrangement allows the lead screw motor 4 to rotate, thereby rotating the lead screw 3. This allows the mounting box 10 to be positioned and moved along the direction of the positioning rods 6, avoiding deviation during the movement, which would affect the laser cutting effect.

[0019] See Figure 2A lead screw motor 13 is installed on one side of the outer wall of the lead screw 12. The lead screw motor 13 is set correspondingly to the lead screw 12. The two ends of the positioning rod 15 are located inside the mounting base 16. The positioning rod 15 and the mounting base 16 are fixedly connected by fastening screws 17. The lead screw motor 13 can make the lead screw 12 rotate, so that the support base 18 can drive the placed circuit board to move and position along the direction of the positioning rod 15. This avoids the support base 18 from shifting during movement, which would affect the cutting effect.

[0020] See Figure 3 There are two cylinders 20, which are symmetrical about the vertical center line of the placement box 19. One end of each cylinder 20 is equipped with a telescopic rod 2001, and a clamping plate 21 is installed on one side of the telescopic rod 2001. Limiting rods 22 are installed on both sides of each cylinder 20. There are two limiting rods 22, one end of which passes through the mounting end 1903 and is fixedly connected to the clamping plate 21. The cylinders 20 can make the telescopic rod 2001 push the clamping plate 21 to limit and clamp the placed circuit board, thus preventing the circuit board from shaking during the laser cutting process, which would affect the cutting effect.

[0021] Working principle: In use, the circuit board to be cut is placed above the placement seat 1901 set in the placement box 19. Then, by opening the cylinder 20, the telescopic rod 2001 pushes the clamping plate 21 to clamp and fix the circuit board, preventing the circuit board from shifting during the cutting process and affecting the cutting effect. Then, by opening the lead screw motor 4, the moving seat 5 moves the mounting box 10, which in turn moves the laser cutting seat 11. Then, by opening the lead screw motor 13, the moving seat 14 moves the support seat 18, which allows the placed circuit board to move, so that the laser cutting seat 11 can easily cut the circuit board. During the cutting process, the air pipe 23 can effectively cool the circuit board and blow away small debris generated during the cutting process, so as not to affect the cutting effect.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
