Description

Technical Field

[0001] The present application relates to the technical field of laser cutting equipment, and in particular to an ultra-short pulse ultraviolet picosecond PCB circuit board laser cutting equipment. Background Art

[0002] The processing of PCB circuit boards is a key link in the electronic manufacturing industry, with complex and delicate technological processes. The processing of PCB circuit boards first requires design planning, including circuit layout, determination of the number of layers, etc. Then, through photolithography technology, the designed circuit pattern is transferred to the copper clad laminate. The ultra-short pulse ultraviolet picosecond PCB circuit board laser cutting equipment is an advanced tool specifically used for cutting PCB circuit boards. It uses ultra-short pulse ultraviolet picosecond laser technology and can achieve high-precision and high-quality cutting and processing of PCB circuit boards.

[0003] After inquiry, the publication number is: CN216031064U, which discloses a PCB circuit board cutting device. In this technology, it is disclosed that "including a workbench and a driving motor installed at the bottom thereof, a sliding seat is slidably connected to the top of the workbench, the position of the sliding seat is adjusted by a displacement adjusting part, the sliding seat is of a hollow structure, a clamping plate is arranged inside the sliding seat, a second lead screw is rotatably connected to the top of the clamping plate, and the second lead screw is threadedly connected to the sliding seat, etc. The technical scheme has a simple structure. Insert the circuit board into the sliding seat, and the part to be cut extends out of the sliding seat and crosses the cutting blade. Adjust the second lead screw, and the second lead screw drives the clamping plate to press down the circuit board to fix it. Drive the cutting blade to rotate through the driving motor, and then rotate the first lead screw. The first lead screw drives the sliding seat to move along the slide rail. During the process that the circuit board gradually contacts the cutting blade, cutting is realized. During the cutting process, there is no need to hold the circuit board by hand, which improves safety and other technical effects".

[0004] Regarding the above related technologies, the inventor believes that in the existing circuit board cutting devices, the position adjustment of the cutting structure is inconvenient. When adjusting the position of the laser cutting part in some laser cutting equipment, relatively simple mechanical structures may be used, and high-precision cooperation such as electric sliders, lead screws, and moving blocks cannot be achieved. As a result, when cutting complex PCB circuit board patterns, it is difficult to accurately control the laser landing point, errors are easily generated, affecting the cutting quality and the finished product rate. Moreover, in the existing circuit board cutting devices, the position adjustment methods of some placement platforms are not flexible and efficient enough, and cannot quickly adapt to the cutting requirements of different specifications of PCB circuit boards, resulting in low work efficiency. In addition, the stability and accuracy retention of some platforms are not good, and vibrations and errors are easily generated during the cutting process, affecting the cutting effect. Therefore, an ultra-short pulse ultraviolet picosecond PCB circuit board laser cutting equipment is needed to solve the above problems. Summary of the Utility Model

[0031] The following will further elaborate on the present application in conjunction with the attached Figure 1 - attached Figure 4 drawings. Example 1

During the entire working process, the indicator light 22 on the upper body 2 displays the working state of the device, the lighting lamp 23 provides lighting, and the operating rod 21 and the buttons are used to operate and control the device.

At the inner end of the electric slider 32, a mounting plate 33 is provided. The mounting plate 33 and the corresponding electric slider 32 are connected by bolts. On the inner side of one of the mounting plates 33, a support plate 34 is welded. At one end of the support plate 34, a motor 35 is welded. The output end of the motor 35 penetrates through the support plate 34 and a lead screw 36 is welded. One end of the lead screw 36 is rotatably connected to the other mounting plate 33. A moving block 37 is threadedly sleeved on the outer surface of the lead screw 36. A limiting column 38 is welded between the two mounting plates 33. The outer surface of the limiting column 38 is sleeved and connected with the moving block 37. At one end of the moving block 37, a laser cutting part 3 is welded. First, after the equipment is started, the lower body 1 provides stable support and a basic structure. The components inside the upper body 2 start to operate. The electric slider 32 slides on the guide rail 31, driving the mounting plate 33 to move, thereby adjusting the position of the laser cutting part 3 in one axial direction. When the motor 35 works, its output end drives the lead screw 36 to rotate, causing the moving block 37 threadedly sleeved on the lead screw 36 to move along the lead screw 36.

[0034] The implementation principle of the embodiment of this application is as follows: The lower body 1 and the upper body 2 form a cutting device. The device is stably placed through the support legs 11. The multiple heat dissipation holes 12 on both sides at one end of the lower body 1 contribute to the timely heat dissipation of the device, ensuring the long-term stable operation of the device and extending the service life of the device. During the entire working process, the indicator lights 22 on the upper body 2 display the working state of the device, the lighting lamp 23 provides lighting, and the operating rod 21 and buttons are used to operate and control the device;

[0035] First, after the equipment is started, the lower body 1 provides stable support and a basic structure. The components inside the upper body 2 start to operate. The electric slider 32 slides on the guide rail 31, driving the mounting plate 33 to move, thereby adjusting the position of the laser cutting part 3 in one axial direction. When the motor 35 works, its output end drives the lead screw 36 to rotate, causing the moving block 37 threadedly sleeved on the lead screw 36 to move along the lead screw 36. At the same time, the moving block 37 is restricted by the limiting column 38 to move stably, completing the adjustment of the second axial position, thereby precisely controlling the position of the laser cutting part 3, being able to achieve high-precision adjustment of the position of the laser cutting part 3, and ensuring the accuracy and precision of cutting. Embodiment 2

The output end of the telescopic air rod 43 is welded to the support block 42. The PCB circuit board is placed on the marble platform 4. When it is necessary to adjust the position of the marble platform 4, the telescopic air rod 43 expands and contracts, and its output end pushes the support block 42 to move, thereby driving the marble platform 4 to move. In cooperation with the laser cutting, the marble platform 4 has good stability and accuracy retention, can provide stable support for the PCB circuit board, reduce vibration and error during the cutting process. The telescopic air rod 43 can flexibly adjust the position of the marble platform 4 to adapt to the cutting requirements of PCB circuit boards of different sizes and shapes.
