Description

Technical Field

[0001] The present application relates to the technical field of circuit board processing, and in particular to a PCB board cutting machine. Background Art

[0002] With the development of the electronics industry, PCB boards are being used more and more widely, and PCB cutting is an important step in the PCB production process. In the field of circuit board processing, cutting machines are often needed to cut circuit boards, such as V-cut processing.

[0003] In the prior art, using a cutting machine to cut PCBs requires complex and time-consuming operations such as adjusting the blade or workpiece, and requires a certain level of operator experience, significantly impacting production efficiency. Existing V-cutting machines also have poor practical performance and are prone to causing circuit boards to wobble and warp during cutting, resulting in poor cutting quality and high losses, leading to low PCB cutting efficiency.

[0004] Therefore, based on the above problems, the existing technology needs to be improved. Utility Model Content

[0005] The purpose of this application is to improve the efficiency of PCB cutting.

[0006] The above technical objectives of the present application are achieved through the following technical solutions: a PCB board cutting machine, comprising a supporting cabinet, the supporting cabinet is provided with a receiving rod for receiving a PCB board; a slide rail is mounted on the supporting cabinet, the slide rail is provided with a slider, the slider is provided with a mounting rod, the mounting rod is provided with a pneumatic clamp, the pneumatic clamp is provided with a limiting column for passing through a limiting hole on the PCB board; a mounting part is provided on the supporting cabinet, the mounting part is provided with a lifting part, the lifting part is provided with an electric cutting knife, and the slider slides on the slide rail toward or away from the electric cutting knife, thereby driving the PCB board to move on the receiving rod toward or away from the electric cutting knife.

[0007] By adopting the above technical solution, the design of the slide rails and sliders enables smooth movement of the PCB board, while the pneumatic clamps and limit posts ensure that the board is fixed in position during the cutting process, thereby achieving efficient and precise cutting, reducing errors and material waste. The pneumatic clamps and limit posts can firmly fix the PCB board, preventing the board from sliding or shifting during cutting. The lifting member adjusts the height of the electric cutting knife to ensure safety during cutting and reduce operational risks. The equipment can adapt to PCB boards of different sizes and shapes. The height adjustment function of the lifting member increases adaptability to boards of varying thicknesses. The overall design is simple and easy to operate, making it easy for workers to use and improving the flexibility and operational efficiency of the equipment.

[0008] Optionally, there are multiple receiving rods, and adjacent receiving rods are arranged in parallel.

[0009] By adopting this technical solution, multiple support rods can more evenly and stably support the PCB, preventing the board from bending or sagging during the cutting process, thereby ensuring cutting accuracy and quality. The multiple support rod design can simultaneously support multiple PCBs or even larger boards, thereby improving the equipment's processing capacity and cutting efficiency to meet diverse production needs. Multiple support rods provide more stable support, reducing the possibility of shaking or shifting the board during cutting, reducing operational risks, and improving the overall safety and reliability of the equipment.

[0010] Optionally, a mounting channel is recessed on the receiving rod, a fixing rod is provided in the mounting channel, and a roller is mounted on the fixing rod, and the roller can rotate on the fixing rod.

[0011] By adopting this technical solution, the roller design allows for smoother movement of the PCB during cutting, reducing friction and ensuring smooth and continuous movement, thereby improving cutting accuracy and efficiency. The roller reduces direct friction between the PCB and the support rod, preventing wear on the support rod and the surface of the PCB over time. This protects all components of the equipment, thereby extending its service life and reducing maintenance costs.

[0012] Optionally, there are multiple installation channels, and the multiple installation channels are evenly spaced apart.

[0013] By employing this technical solution, the evenly distributed mounting channels ensure that the fixing rods and rollers are evenly distributed on the support rod, providing more uniform and stable support. This effectively prevents tilting, shaking, or deformation of the PCB during cutting, improving cutting precision and stability. By rationally spacing the multiple mounting channels and rollers, they more effectively distribute the weight and pressure of the board, reducing the load on each roller and fixing rod, thereby reducing wear and damage to the rollers and fixing rods, and improving the durability and reliability of the equipment. This design also speeds up board movement and adjustment, further improving overall cutting efficiency.

[0014] Optionally, a receiving groove is provided in the supporting cabinet.

[0015] By adopting this technical solution, the collection trough effectively collects the powder generated during the cutting process, preventing it from scattering in the work area and maintaining a clean and tidy working environment. This not only improves the hygiene of the working environment but also reduces the frequency and difficulty of cleaning the work area. Effective collection of cutting powder reduces the possibility of powder dispersal in the air, lowering the risk of dust inhalation for operators, improving the air quality of the working environment, and enhancing operational safety. This plays a significant role in protecting worker health and safety.

[0016] Optionally, there are multiple pneumatic clamps, and the multiple pneumatic clamps are evenly spaced apart.

[0017] By adopting this technical solution, multiple evenly distributed pneumatic clamps can more firmly and evenly secure the PCB, preventing movement or shaking during the cutting process, thereby improving cutting stability and precision. The equipment can flexibly adjust the position of the pneumatic clamps to accommodate PCB panels of varying sizes and shapes. Whether large or small, the pneumatic clamp position can be adjusted to achieve optimal securing, enhancing the equipment's adaptability and versatility. Multiple pneumatic clamps can operate simultaneously to quickly and evenly secure the PCB, reducing the time required to adjust individual clamps one by one, thereby improving overall operational efficiency and productivity. Furthermore, the multi-pneumatic clamp design reduces downtime caused by single clamp failure, improving equipment reliability and operational efficiency.

[0018] Optionally, a cover is further provided on the supporting cabinet.

[0019] By adopting this technical solution, the cover effectively shields operating components within the machine, such as the electric cutter, preventing operators from accidentally touching or injuring themselves, thereby improving operational safety. Furthermore, the cover prevents dust and debris generated during the cutting process from scattering into the surrounding environment, reducing pollution in the work environment and protecting the health of operators. The cover effectively prevents external environmental factors such as dust and moisture from entering the machine, protecting internal components from corrosion and damage. This helps extend the life of the equipment, reduces maintenance and replacement costs, and improves its reliability and stability.

[0020] Optionally, an observation hole is provided on the cover body, and a shielding member is provided on the cover body for shielding the observation hole, and the shielding member is made of a light-transmitting material.

[0021] By adopting this technical solution, the operator can clearly see the internal operating status of the machine through the observation hole, including the position of the workpiece during the cutting process and the operation of the cutting blade. The shield is made of a translucent material to block the entry of dust and debris, while ensuring the transparency of the observation hole, improving the convenience and visibility of operation. The operator can directly observe the cutting process without stopping the machine and opening the cover to observe, saving operation time and improving work efficiency. The presence of the observation hole also allows for the timely detection of abnormalities during the cutting process, facilitating timely resolution and further improving production efficiency.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. The design of the slide rails and sliders enables smooth movement of the PCB, while the pneumatic clamps and limit posts secure the board in place during the cutting process, enabling efficient and precise cutting, minimizing errors and material waste. The pneumatic clamps and limit posts securely hold the PCB in place, preventing it from sliding or shifting during cutting. The lift adjusts the height of the electric cutting blade, ensuring safety and minimizing operational risks. The equipment can accommodate PCBs of varying sizes and shapes, and the height adjustment function of the lift increases adaptability to varying thicknesses. The overall design is simple and easy to operate, making it easy for workers to use and improving the equipment's flexibility and operational efficiency.

[0024] 2. Multiple, evenly distributed pneumatic clamps secure the PCB more securely and evenly, preventing movement or shaking during cutting, thereby improving cutting stability and precision. The equipment can flexibly adjust the position of the pneumatic clamps to accommodate PCB board sizes and shapes. Whether large or small, the pneumatic clamp position can be adjusted to achieve optimal securing, enhancing the equipment's adaptability and versatility. Multiple pneumatic clamps can operate simultaneously to quickly and evenly secure the PCB board, reducing the time required to adjust individual clamps one by one, thereby improving overall operational efficiency and productivity. Furthermore, the multiple pneumatic clamp design reduces downtime caused by individual clamp failures, improving equipment reliability and operational efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] In this embodiment, referring to Figure 1-4 A PCB board cutting machine includes a support cabinet 1, which is provided with a plurality of supporting rods 2 for supporting PCB boards 3. These supporting rods 2 are arranged adjacently and in parallel to provide uniform and stable support. Slide rails 4 and sliders 5: The support cabinet 1 is provided with slide rails 4, and the slide rails 4 are provided with sliders 5, which can move up and down along the slide rails 4. Mounting rods 6 and pneumatic clamps 7: The sliders 5 are provided with mounting rods 6, and the mounting rods 6 are provided with pneumatic clamps 7. The pneumatic clamps 7 are used to fix the PCB board 3 to ensure that its position is stable during the cutting process. Limiting column 8: The pneumatic clamp 7 is provided with a limiting column 8, which is used to penetrate the limiting holes 9 on the PCB board 3 to ensure that the PCB board 3 is accurately fixed in the position. Mounting part 10 and lifting part 11: The support cabinet 1 is provided with a mounting part 10, and the mounting part 10 is provided with a lifting part 11. The lifting part 11 is provided with an electric cutting knife 12, and the height of the cutting knife can be adjusted.

[0034] The position of the electric cutting knife 12 is adjusted by moving the slider 5 on the slide rail 4, thereby controlling the moving direction of the PCB board 3 on the receiving rod 2 to achieve cutting of the PCB board 3.

[0035] When cutting a PCB board 3, first ensure the cutter is stopped. Place the PCB board 3 to be cut on the support rod 2 supporting the cabinet 1 and adjust the position to ensure stability. Turn on the cutter's power switch to ensure proper power supply. Check that all components, such as the slide rail 4, pneumatic clamp 7, and electric cutter 12, are functioning properly. Adjust the height of the cutter as needed to ensure the required cutting depth. Adjust the position of the pneumatic clamp 7 on the mounting rod 6 according to the size and requirements of the PCB board 3. Open the pneumatic clamp 7 and move it to the edge of the PCB board 3. Pass the limit pin 8 of the pneumatic clamp 7 through the limit hole 9 on the PCB board 3 to secure the PCB board 3 in the cutting position. Press the start button on the electric cutter 12 to start the cutter. Control the movement of the slider 5 on the slide rail 4 to move the PCB board 3 along the support rod 2 toward the electric cutter 12 to begin cutting. Observe the contact between the cutter and the PCB board 3 to ensure smooth cutting. Regularly check the securement of the PCB board 3 to maintain its stability. When the cutting reaches the predetermined position, stop the electric cutter 12. Close the pneumatic clamp 7 and remove the cut PCB board 3. Turn off the power switch of the cutting machine and disconnect the power supply. Clean and maintain the equipment to keep it in good condition.

[0036] In this embodiment, referring to Figure 1 and Figure 5 , a plurality of receiving rods 2 are provided on the supporting cabinet 1 for receiving the PCB board 3. A plurality of mounting channels 13 are recessed on each receiving rod 2. A fixing rod 14 is provided in the mounting channel 13 on each receiving rod 2, and a roller 15 is mounted on the fixing rod 14. These mounting channels 13 are evenly spaced to ensure the stability and uniform distribution of the fixing rods 14 and the rollers 15. The rollers 15 can rotate freely on the fixing rods 14 so that the PCB board 3 can be moved and adjusted more smoothly during transportation or cutting, while reducing friction and improving cutting accuracy. Through this embodiment, the PCB board 3 cutting machine can effectively fix and support the PCB board 3, and through the design of the rollers 15, the position and direction of the board can be adjusted more flexibly, thereby achieving efficient and accurate cutting operations.

[0037] In this embodiment, referring to Figure 1The support cabinet 1 is recessed with a receiving groove 16, corresponding to the multiple receiving rods 2. These grooves effectively collect the powder generated during the cutting process, preventing it from scattering in the work area and maintaining a clean and tidy working environment. This not only improves the sanitation of the working environment but also reduces the frequency and difficulty of cleaning the work area. Effectively collecting cutting powder reduces the possibility of powder dispersal in the air, lowering the risk of dust inhalation by operators, improving the air quality of the working environment, and enhancing operational safety. This plays a significant role in protecting the health and safety of workers.

[0038] In this embodiment, referring to Figure 1 A plurality of pneumatic clamps 7 are provided on the mounting rod 6. The spacing between adjacent pneumatic clamps 7 is adjustable to use PCB boards 3 of different specifications. Preferably, the plurality of pneumatic clamps 7 are evenly spaced. The evenly distributed plurality of pneumatic clamps 7 can fix the PCB board 3 more firmly and evenly, preventing the board from moving or shaking during the cutting process, thereby improving the stability and accuracy of the cutting.

[0039] In this embodiment, referring to Figure 1 A cover 17 is mounted on the support cabinet 1 to block dust and debris generated during the cutting process and prevent the operator from accidentally touching the moving parts of the cutting machine. A viewing hole 18 is provided in the cover 17 to allow the operator to observe the cutting process. This viewing hole 18 is shielded by a shield 19 made of a light-transmitting material, such as transparent plastic or glass. This allows the operator to clearly observe the cutting process through the shield 19 while preventing dust and debris from splashing onto the operator.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
