The quality of PCB drilling directly affects the performance and reliability of the circuit board. Therefore, it is necessary to strictly control various process parameters during the production process to ensure processing quality.

[0003] Existing dust removal devices for drilling on PCBs are used in structural parts that collect dust. Their positions are generally fixed, making it difficult to adjust them to accommodate changes in hole diameter during processing. This can easily lead to situations where, when drilling small holes, the distance between the work point and the dust collection point is too far, resulting in untimely dust removal and excessive dust contamination of the board.

This solves the problem mentioned in the background art that the structure of the dust collection part of some existing PCB board drilling dust removal devices is generally fixed in position, making it difficult to adjust the position according to the changes in hole diameter during processing. This easily leads to the problem that when drilling small holes, the distance between the working point and the dust collection end is far, resulting in untimely dust removal and excessive dust pollution of the board body.

A base is fixedly connected to the inner side of the base frame. A second screw is threadedly connected to the inner side of the base frame. A moving block is rotatably connected to the outer side of one end of the second screw. A suction cup is fixedly connected to one side of the moving block. A connecting pipe is fixedly connected to one side of the suction cup. A spring-shaped hose is fixedly connected to one end of the connecting pipe. An air pump is fixedly connected to one end of the spring-shaped hose. The base frame is fixedly connected to one side of the air pump. A dust discharge pipe is fixedly connected to the output end of the air pump. By adjusting the spacing between the suction cups, the suction cups can be brought closer to the drilling point, ensuring the effectiveness of dust collection and discharge.

[0013] Compared with the prior art, this utility model provides a dust removal device for PCB board drilling, which has the following beneficial effects: 1. This utility model features a base frame with a lifting screw fixedly connected to the top. A ground ring is slidably connected to the outer side of the lifting screw, and a limit nut is threadedly connected to the outer side of the top of the lifting screw. A base is fixedly connected to the inner side of the base, and a second screw is threadedly connected to the inner side of the base. A moving block is rotatably connected to the outer side of one end of the second screw, and a suction cup is fixedly connected to one side of the moving block. The connecting mechanism, along with the clamps on both sides, is fitted against the outer wall of the output shaft of the drilling equipment. Then, the first screw is connected to the corresponding connecting piece. The connecting mechanism is fixedly connected to the outer side of the drilling equipment shaft. Then, according to the required drill rod length, each lifting screw is raised or lowered to the required height inside the ground ring. Then, the limit nut is rotated until its bottom contacts the top of the ground ring, setting the initial height of the base frame. By directly squeezing the knob, each second screw is rotated within the base. The rotation of the second screw inside the moving block moves each suction cup. The suction cup is moved to a position close to the drilling point. During this process, the spring-shaped hose, influenced by the material of the structure, deforms and extends to accommodate the positional changes of the suction cup during its movement. Finally, a sufficiently long external hose is connected to the dust exhaust pipe. The air pump is turned on, and as the PCB board drilling equipment lowers the drill rod to drill, the connecting mechanism moves synchronously down the outer wall of the equipment's rotating shaft. This causes the buffer pad to contact the top of the board first, continuously pressing down to drill. The ground ring slides down the outer wall of the lifting screw, thus maintaining the current position of the bottom frame. The dust generated by the drill rod at the output end of the rotating shaft during the drilling process is collected by the suction cup near the drilling point, and then transmitted through the connecting pipe to the spring-shaped hose before being discharged by the air pump from the dust exhaust pipe. This effectively adjusts the distance between the suction cup and the drilling point according to the size of the hole during PCB board drilling, thereby ensuring the dust removal effect of the device and reducing the risk of dust contamination of the board surface. 2. This utility model features a knob with a second screw fixedly connected to one end, and a base threadedly connected to the outer side of the second screw, which allows for convenient and easy manipulation and rotation by personnel. 3. By setting a first sliding rod, with a base slidably connected to the outside of the first sliding rod and a moving block fixedly connected to one end of the first sliding rod, the present invention can effectively ensure the stability of the position of the moving block during the translation process.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

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.

[0017] Please see Figure 1-4This utility model provides a technical solution: a dust removal device for drilling PCB boards, including a connecting mechanism 1 and a dust collection mechanism 2 disposed inside the connecting mechanism 1 for adjusting the spacing to adapt to different hole diameters. The dust collection mechanism 2 includes lifting screws 201 symmetrically arranged and slidably connected to the inner side of a ground ring 102. A limit nut 202 is threadedly connected to the outer side of the top end of the lifting screw 201. A base frame 203 is fixedly connected to the bottom end of the lifting screw 201.

A connecting pipe 208 is fixedly connected to one side of the suction cup 207. A spring-shaped hose 209 is fixedly connected to one end of the connecting pipe 208. An air pump 210 is fixedly connected to one end of the spring-shaped hose 209. The bottom frame 203 is fixedly connected to one side of the air pump 210. The output end of the air pump 210 is fixedly connected to the dust exhaust pipe 211. By adjusting the distance between each suction cup 207, the suction cup 207 can be brought closer to the drilling point, ensuring the dust collection and exhaust effect. Set the initial height of the base frame 203, and directly squeeze the knob 4 to rotate each second screw 212 inside the base 205. Through the rotation of the second screw 212 inside the moving block 206, each suction cup 207 is moved to a position close to the drilling point. Finally, connect the sufficiently long external hose to the dust exhaust pipe 211 and turn on. During the drilling process, the air pump 210 drives the connecting mechanism 1 to move synchronously down the outer wall of the equipment shaft, causing the buffer pad 9 to contact the top of the board first and continuously press down to drill. This causes the ground ring 102 to slide down the outer wall of the lifting screw 201, thereby maintaining the current position of the bottom frame 203. The dust generated by the drill rod at the output end of the shaft during the drilling process is collected by the suction cup 207 near the drilling point, and then transmitted through the connecting pipe 208 to the spring-shaped hose 209 and discharged by the air pump 210 through the dust discharge pipe 211.

[0018] In this utility model, preferably, the connecting mechanism 1 includes symmetrically arranged clamping plates 101. A ground ring 102 is fixedly connected to the bottom of the outer side of the clamping plate 101. A plurality of connecting plates 103 are symmetrically arranged on the outer side of the clamping plate 101. A first screw 104 is threadedly connected to the inner side of the connecting plate 103. The connecting mechanism 1 is fitted with the clamping plates 101 on both sides and attached to the outer wall of the output shaft of the drilling equipment. Then, the first screw 104 is connected to the corresponding connecting plate 103, and the connecting mechanism 1 is fixed on the outer side of the shaft end of the drilling equipment.

[0019] In this utility model, preferably, a clamping pad 3 is fixedly connected to one side of the clamping piece 101. The clamping pad 3 is made of flexible material and has an arc-shaped structure, which can effectively fit the outer wall of the rotating shaft of the hole-opening device and reduce the wear on its surface.

[0020] In this utility model, preferably, a knob 4 is fixedly connected to one end of the second screw 212, a base 205 is threadedly connected to the outer side of the second screw 212, and a bottom frame 203 is fixedly connected to the outer side of the base 205, which can effectively facilitate personnel to directly pinch and rotate.

[0021] In this utility model, preferably, a limiting spring 5 is movably connected to the outer side of one end of the second screw 212. The limiting spring 5 is located between the base 205 and the knob 4, which can effectively reduce the loosening of the second screw 212 during long-term use.

[0022] In this utility model, preferably, a buffer pad 9 is fixedly connected to the bottom of the bottom frame 203. The buffer pad 9 is made of flexible material, which can effectively reduce the wear on the surface of the plate during the limiting process.

[0023] In this utility model, preferably, a plurality of top plates 7 are symmetrically arranged on one side of the top of the bottom frame 203, and a second slide rod 8 is fixedly connected to the top of each top plate 7. A ground ring 102 is slidably connected to the outer side of each second slide rod 8, which can effectively ensure the stability of the bottom frame 203 during the lifting process.

[0024] In this utility model, preferably, a first slide rod 6 is symmetrically arranged on the outer side of the moving block 206, and a base 205 is slidably connected to the outer side of the first slide rod 6, which can effectively ensure the stability of the position of the moving block 206 during the translation process.

[0025] The working principle and usage process of this utility model are as follows: In use, the connecting mechanism 1, along with the clamping plates 101 on both sides, is attached to the outer wall of the output shaft of the drilling equipment. Then, the first screw 104 is connected to the corresponding connecting plate 103. The connecting mechanism 1 is fixed on the outer side of the drilling equipment shaft. Then, according to the required drill rod length, each lifting screw 201 is raised or lowered to the required height inside the ground ring 102. Then, the limiting nut 202 is rotated until its bottom contacts the top of the ground ring 102, setting the initial height of the base frame 203. The knob 4 is then squeezed, and each second screw 212 is rotated within the base 205. Through the rotation of the second screw 212 inside the moving block 206, each suction cup 207 is moved to a position close to the drilling point. During this process, the spring-shaped flexible hose 209, influenced by the material of the structure, deforms and extends to accommodate the suction cups. During the movement of 207, the position changes, and finally, a sufficiently long external hose is connected to the dust exhaust pipe 211. The air pump 210 is turned on. As the PCB board drilling equipment lowers the drill rod to drill, the connecting mechanism 1 moves down synchronously on the outer wall of the equipment shaft, causing the buffer pad 9 to contact the top of the board first. The continuous downward pressure of drilling causes the ground ring 102 to slide down on the outer wall of the lifting screw 201, thereby maintaining the current position of the bottom frame 203. The dust generated by the drill rod at the output end of the shaft during the drilling process is collected by the suction cup 207 near the drilling point, and then transmitted through the connecting pipe 208 to the spring-shaped hose 209 and discharged by the air pump 210 from the dust exhaust pipe 211. This can effectively adjust the distance between the suction cup 207 and the drilling point according to the size of the hole during the PCB board drilling operation, thereby ensuring the dust removal effect of the device and reducing the risk of dust contamination of the board surface.

[0026] 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.
