[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Compared with other cutting methods, laser cutting features high speed, high precision, and high adaptability, and is widely used in PCB board production. Due to the short product update cycle of electronic products, PCB board production involves rapid updates to models and specifications, leading to increased costs associated with upgrading the corresponding processing equipment.

[0024] Example 1:

[0025] Some cutting machines cannot flexibly adapt to PCB boards of different sizes and shapes, resulting in additional time being spent on equipment setup and calibration when processing new products. To solve the above problems, combined with Figures 1-5 As shown, the present invention provides an automatic PCB board cutting machine, including a frame 1 serving as the carrier of the entire device. An outer cover 2 is fixedly connected to the frame 1, and conveying ports 3 for PCB boards to enter and exit are opened on both sides of the outer cover 2. A base is also fixedly connected to the frame 1, and a cutting head 6 is provided on the base, as well as a shifting mechanism for driving the cutting head 6 to move according to the cutting path. A conveying mechanism for moving the PCB board is also provided on the base. After the PCB board moves into the outer cover 2, the cutting head 6 can cut the PCB board. The movement of the cutting head 6 can be precisely controlled according to the preset cutting path, thereby ensuring high precision and consistency in the cutting process and avoiding human error.

[0026] Because there is a slight error in the time when each PCB board enters the equipment, in order to control the position of the PCB board entering, the conveying mechanism includes frames 10 on both sides of the substrate. Each of the two frames 10 has a logistics belt 18 on its opposite side. Product blocking cylinder 12 and product blocking cylinder 2 11 are respectively installed on the frames 10 to contact the PCB board and brake the logistics belt 18. Pressure plates 17 for fixing the PCB board are also provided on both sides of the frames 10. When the PCB board moves and comes into contact with product blocking cylinder 12 and product blocking cylinder 2 11, the PCB board stops moving and the pressure plate 17 will fix the PCB board. Then the PCB board can be cut and processed.

[0027] Specifically, a clamping cylinder 20 is installed on the frame 10 to drive the pressure plate 17 to move up and down. The pressure plate 17 is fixed to the free end of the clamping cylinder 20. The clamping cylinder 20 can control the pressure plate 17 to move up and down to fix the pressure plate 17, so as to prevent the PCB board from shifting during cutting and improve the cutting quality.

[0028] Furthermore, the Z-axis moving component 19 is also equipped with a CCD vision positioning component 9, which includes a CCD camera, and can perform precise positioning of the PCB board by taking pictures.

[0029] The frame 1 contains an electrical control box 5, and the outer cover 2 is equipped with a control panel 4.

[0030] As can be seen from the embodiments, the corresponding product specifications can be automatically adjusted according to production needs, realizing rapid replacement of product specifications in production. This can meet the needs of rapid replacement of multiple product specifications, saving equipment investment costs and product specification replacement and debugging time.

[0031] Example 2:

[0032] Because manually adjusting the cutting path is prone to human error, especially with complex shapes and narrow paths, it can lead to insufficient cutting precision and affect the quality of the final product. To address these issues, a solution is proposed that combines... Figure 3As shown, based on Embodiment 1, each frame 10 is provided with a logistics belt adjustment edge 15 and a logistics belt fixing edge 16. A logistics line width adjustment component 14 is fixedly mounted on the base. The two frames 10 are respectively located on both sides of the logistics line width adjustment component 14, which is used to drive the two frames 10 to move in opposite directions. The logistics line width adjustment component 14 includes a servo motor, a bidirectional lead screw, and a transmission block threadedly connected to the bidirectional lead screw. The servo motor starts and drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw drives the transmission blocks on both sides to move in opposite directions, so that the two frames 10 can move in opposite directions, thereby conveying PCB boards of different widths. Two logistics belt motors 13 are installed on the frame 10 to drive the logistics belt line 18 to run. They can be precisely adjusted according to the width of different products, thereby reducing material waste and ensuring the accuracy of cutting.

[0033] Specifically, the conveying mechanism includes Y-axis linear motion components 7 installed on both sides of the base, an X-axis linear motion component 8 between the two Y-axis linear motion components 7, a Z-axis motion component 19 on the X-axis linear motion component 8, and a cutting head 6 installed on the Z-axis motion component 19. The X-axis linear motion component 8, the Y-axis linear motion component 7, and the Z-axis motion component 19 are all composed of servo motors and lead screws, and are the same as existing motion components, capable of driving objects to move linearly.

[0034] As can be seen from the above embodiments: according to the product specifications, the corresponding program is loaded, and the logistics line width adjustment servo component drives the lead screw to rotate via the servo motor to adjust the width of the logistics belt 18 to the corresponding product width; then the PCB board enters the outer cover 2 through the logistics belt 18, and stops after encountering the product blocking cylinder 12 and the product blocking cylinder 21. The pressing cylinder 20 on the logistics belt 18 drives the pressure plate 17 to press down and fix the PCB board product; the X-axis linear movement component 8 and the Y-axis linear movement component 7 drive the CCD vision positioning component 9 to move to the four corners of the product to take pictures and precisely position the product. Then, the Z-axis movement component 19 drives the cutting head 6 to adjust to the cutting process focal length height and cut the product through the cutting program trajectory; after the cutting is completed, the pressing cylinder 20 rises, the product blocking cylinder 12 and the product blocking cylinder 21 descend, and the logistics belt 18 carries the PCB board out of the frame 1 and is transmitted to the next process.

[0035] When changing production models, simply load the corresponding product production program into the computer, and the logistics conveyor belt 18 will automatically adjust its width to fit the product width. After the product is fixed in the outer cover 2, it will be processed according to the corresponding cutting program.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
