Description

Technical Field

[0001] This utility model relates to the field of PCB board production, and in particular to a dust prevention device for cutting materials. Background Technology

[0002] The dust-proof cutting device is a closed-loop cutting system that uses negative pressure suction to ensure a dust-free process throughout the PCB substrate cutting process. This prevents dust from causing drill holes to deviate or become unusable, and also protects the cleanliness of the workshop environment and the health of personnel.

[0003] The existing cutting equipment has problems such as cutting debris polluting the workshop environment, harming the health of operators, and dust on the board causing drilling deviations and scrap due to the lack of a closed cutting area and dust removal function.

[0004] Therefore, in view of the problems of existing cutting devices lacking dust removal function, such as debris polluting the workshop environment, harming personnel health, and causing drilling deviation and scrap, there is an urgent need to design a new type of cutting dust prevention device. Utility Model Content

[0005] In order to overcome the problems of existing cutting equipment lacking dust removal function, which leads to debris polluting the workshop environment, harming the health of personnel, and causing drilling deviation and scrapping.

[0006] The technical solution of this utility model is as follows: a dustproof cutting device, including a base; and a lead screw. An installation frame is fixedly installed on the upper end of the base. The installation frame has symmetrical installation slots on both the left and right sides. A main lifting frame is fixedly installed inside the two right-side installation slots. A motor is fixedly installed on the upper end of the main lifting frame. The two ends of the lead screw are rotatably connected to the inner walls of their respective main lifting frames. The output end of the motor is fixedly connected to the lead screw. The motor is used to drive the lead screw to rotate. A main slider is threadedly connected to the outer surface of the lead screw. A lifting plate is fixedly installed on the left end of the main slider. Several springs are fixedly installed on the lower end of the lifting plate. A stop block is fixedly installed on the lower end of each spring. A symmetrical installation wall is fixedly installed on the upper end of the installation frame. A dust suction module is provided on the left end of the installation frame. A collection module, an auxiliary displacement module, and a balancing air pressure module are provided on the lower end of the dust suction module.

[0007] Preferably, by setting a motor, the motor drives the lead screw to rotate when running. When the lead screw rotates, it restricts the rotation of the main slider through the main lifting frame, thereby driving the main slider to move. When the main slider moves, it drives the lifting plate and its connecting parts to move together, so that the stop block cooperates with the mounting wall to close the front and rear ends of the mounting frame. With the elasticity of the spring, it has a certain degree of autonomous adaptation space. After the two ends of the mounting frame are closed, the dust collection module is activated to clean up the debris generated during the internal cutting process. This achieves the purpose of preventing pollution of the workshop environment and harm to the operator's health, and solves the problem of existing cutting devices, which have problems such as cutting debris polluting the workshop environment, harming the health of operators, and dust on the board causing drilling deviation and scrap due to the lack of a closed cutting area and dust removal function.

[0008] Preferably, the vacuuming module includes vacuum pipes, and the inner left end of the mounting frame has a symmetrical through groove. Two vacuum pipes are fixedly connected to their corresponding through grooves, and the left ends of the two vacuum pipes are fixedly connected to a manifold. A vacuum pump is fixedly installed at the lower end of the manifold.

[0009] Preferably, the collection module includes a collection chamber, which is fixedly connected to a vacuum pump, and a storage drawer is slidably connected inside the collection chamber.

[0010] Preferably, the auxiliary displacement module includes a roller, and a connecting groove is provided at the lower end of the collection compartment. The roller is rotatably connected to the connecting groove, and the outer surface of the roller is in contact with the lower end of the storage drawer.

[0011] Preferably, the air pressure balancing module includes a filter screen, and a vent is provided on the upper rear side of the collection chamber, with the filter screen and the vent being fixedly connected.

[0012] Preferably, a secondary lifting frame is fixedly installed inside each of the two mounting slots on the right side. A limit rod is fixedly installed inside the secondary lifting frame, and a secondary slider is slidably connected to the outer surface of the limit rod. The right end of the secondary slider is fixedly connected to the left end of the lifting plate.

[0013] Preferably, several slide rails are fixedly installed on the opposite sides of both mounting walls, and the surfaces of several stops are provided with sliding grooves, which are slidably connected to the slide rails.

[0014] The beneficial effects of this utility model are: 1. The motor-driven stop blocks automatically close the front and rear ends of the mounting frame, and combined with the elastic adaptive adjustment of the spring, ensure a tight fit between the frame and the mounting wall, thereby forming a closed space during the material cutting process. At the same time, the dust collection module can promptly absorb the debris generated inside, significantly reducing the spillage of dust and debris, effectively preventing the workshop environment from being polluted, maintaining the cleanliness of the work area, and meeting the high standards of environmental protection and hygiene requirements of modern manufacturing. 2. The installation frame is enclosed and debris is cleaned through automated control without manual intervention, which greatly reduces the risk of operators coming into direct contact with high-speed flying debris or dust. This not only reduces occupational health problems caused by inhaling harmful particles, but also avoids safety hazards caused by manual cleaning, thereby improving the overall safety of the production process and the occupational health protection level of operators.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5This utility model provides an embodiment of a material cutting dust prevention device, including a base 1 and a lead screw 6. A mounting frame 2 is fixedly installed on the upper end of the base 1. The mounting frame 2 has symmetrical mounting grooves 3 on both the left and right sides. A main lifting frame 4 is fixedly installed inside each of the two right-side mounting grooves 3. A motor 5 is fixedly installed on the upper end of the main lifting frame 4. The two ends of the lead screw 6 are rotatably connected to the inner walls of their respective main lifting frames 4. The output end of the motor 5 is fixedly connected to the lead screw 6, and the motor 5 drives the lead screw 6 to rotate. A main slider 7 is threaded onto the outer surface of the lead screw 6. A lifting plate 9 is fixedly installed on the left end of the main slider 7. Several springs 10 are fixedly installed on the lower end of the lifting plate 9, and stops 11 are fixedly installed on the lower ends of each spring 10. The mounting frame 2... The upper part of the internal structure is fixedly equipped with symmetrical mounting walls 8. The left end of the internal structure of the mounting frame 2 is equipped with a dust collection module. The lower end of the dust collection module is equipped with a collection module, an auxiliary displacement module, and a balancing air pressure module. A motor 5 is installed. When the motor 5 runs, it drives the lead screw 6 to rotate. When the lead screw 6 rotates, it restricts the rotation of the main slider 7 through the main lifting frame 4, thereby driving the main slider 7 to move. When the main slider 7 moves, it drives the lifting plate 9 and its connecting parts to move together. This allows the stop block 11 to cooperate with the mounting walls 8 to close the front and rear ends of the mounting frame 2. With the elasticity of the spring 10, it has a certain degree of self-adaptation space. After the two ends of the mounting frame 2 are closed, the dust collection module is activated to clean up the debris generated during the internal cutting process, thereby preventing pollution of the workshop environment and harm to the operator.

[0019] Please see Figures 1-5In this embodiment, the vacuuming module includes a vacuum pipe 13. A symmetrical through-groove 12 is provided at the left end of the mounting frame 2. Two vacuum pipes 13 are fixedly connected to their corresponding through-groove 12. A manifold 14 is fixedly connected to the left end of the two vacuum pipes 13. A vacuum pump 15 is fixedly installed at the lower end of the manifold 14. By setting the vacuum pump 15, when the vacuum pump 15 is running, it pumps out the cutting debris inside the mounting frame 2 through the vacuum pipes 13 and the manifold 14, thereby achieving the purpose of cleaning the debris generated during cutting. The collection module includes a collection chamber 16, which is fixedly connected to the vacuum pump 15. A storage drawer 17 is slidably connected inside the collection chamber 16. By setting the collection chamber 16, when the vacuum pump 15... During operation, the extracted cutting debris is collected in the collection chamber 16 and held by the internal storage drawer 17. When the storage drawer 17 is full, the staff can pull it out for cleaning, thus achieving the purpose of centralized cleaning of the extracted cutting debris. The auxiliary displacement module includes a roller 19. The lower end of the collection chamber 16 has a connecting groove 18. The roller 19 is rotatably connected to the connecting groove 18. The outer surface of the roller 19 is in contact with the lower end of the storage drawer 17. By setting the roller 19, the lower end of the storage drawer 17 and the lower end of the collection chamber 16 are in a rolling connection, reducing the contact friction and making it easier for the staff to pull out the storage drawer 17, thereby assisting the staff in their work.

[0020] Please see Figures 1-5In this embodiment, the air pressure balancing module includes a filter screen 21. A vent 20 is provided on the upper rear side of the collection chamber 16. The filter screen 21 is fixedly connected to the vent 20. By setting the vent 20, the vacuum pump 15 can balance the air pressure inside the collection chamber 16 during operation, allowing the vacuum pump 15 to operate efficiently. Furthermore, by setting the filter screen 21, cutting debris is prevented from being discharged along with excess air, thereby ensuring the stable operation of the vacuum pump 15. A secondary lifting frame 22 is fixedly installed inside each of the two mounting slots 3 on the right side. A limit rod 23 is fixedly installed inside the secondary lifting frame 22. A secondary slider 24 is slidably connected to the outer surface of the limit rod 23. The right end of the secondary slider 24 is fixedly connected to the left end of the lifting plate 9. Block 24, the auxiliary slider 24 and the lifting plate 9 are connected. When the lifting plate 9 moves, it drives the auxiliary slider 24 to move. The degree of freedom of the auxiliary slider 24 is restricted by the setting of the limit rod 23, thereby providing support for the other end of the lifting plate 9, so as to achieve the purpose of assisting the lifting plate 9 to move stably. Several slide rails 26 are fixedly installed on the opposite sides of the two mounting walls 8. The surface of several blocks 11 is provided with a slide groove 25. The slide groove 25 is slidably connected to the slide rail 26. By setting the slide rail 26 and the slide groove 25, the blocks 11 are slidably connected by the cooperation of the slide groove 25 and the slide rail 26, and the degree of freedom is restricted when they move, so as to avoid the spring 10 from bending when compressed, causing the blocks 11 to deviate, thereby achieving the purpose of stable operation of the blocks 11.

[0021] During operation, the motor 5 is first started by the external controller, which drives the lifting plate 9 to move the spring 10 and the stop block 11 synchronously to close both ends of the mounting frame 2. Then, the vacuum pump 15 is started to suck the cutting debris into the collection chamber 16 through the dust suction pipe 13 and the manifold 14. During this period, the vent 20 and the filter screen 21 maintain air pressure balance. When the storage drawer 17 is full, it can slide out along the roller 19 to clean up the debris.

[0022] Through the above steps, by setting up motor 5, after motor 5 starts, it drives lead screw 6 to rotate. When lead screw 6 rotates, the main lifting frame 4 restricts the rotational freedom of main slider 7, forcing main slider 7 to move in a straight line. The linear movement of main slider 7 pushes lifting plate 9 and its connected parts to move synchronously, so that stop block 11 cooperates with mounting wall 8 to close the front and rear ends of mounting frame 2. At the same time, the elastic deformation of spring 10 maintains a moderate adaptive adjustment capability. After the two ends of mounting frame 2 are completely closed, the dust collection module is immediately started to thoroughly remove the debris generated by the cutting process inside mounting frame 2, effectively avoiding the situation where debris pollutes the workshop environment and harms the health of operators. This solves the problem that existing cutting devices, due to the lack of a closed cutting area and dust removal function, cause cutting debris to pollute the workshop environment, harm the health of operators, and cause drilling deviation and scrap due to board dust.
