Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to a punching device for circuit board processing. Background Art

[0002] Perforating a circuit board refers to the process of drilling holes into the surface of a circuit board using a drill bit. Traditional perforating equipment typically positions the circuit board first, then controls the movement of the drill bit to perform the perforation. The drill bit uses a twist drill that can remove chips. However, during the drilling process, due to the threads on the outside of the twist drill, debris is easily left on the surface. Furthermore, some slag often remains in the completed hole. Common slag consists mainly of various dusts such as copper foil, copper wire, glass fiber, and PP powder. Excessive residue can cause hidden dangers in subsequent electroplating production and processing, such as uneven copper plating thickness and lack of metal in the hole. Existing perforating equipment makes it difficult to handle the slag in the hole. To this end, we propose a perforating device for circuit board processing. Summary of the Invention

The first air cylinder 11 is provided with an air inlet valve 12 and an air outlet valve 13. The first air pipe 14 is located between the first air cylinder 11 and the pipe body 15. An air hole 18 is provided on the tube body 15; the rotating mechanism includes a transmission assembly 19, a transmission shaft 20, a driving gear 21, a driven gear 22, a second ring member 29, a guide assembly and an elastic telescopic assembly. The transmission shaft 20 is transmitted and cooperated with the driving member 9 through the transmission assembly 19, and the guide assembly and the elastic telescopic assembly are both arranged between the driven gear 22 and the second ring member 29; the transmission assembly 19 is composed of a transmission wheel and a transmission belt, and the driving member 9 is a dual-axis motor, one output shaft of which is connected to the drill bit 10, and the other output end is connected to the transmission wheel through a retractable drive shaft. The guide assembly includes a guide seat 30, a support plate 33 and a connecting shaft 34. The guide seat 30 is provided with a guide groove 31 and a groove 32. The guide groove 31 slides with the second ring member 29, and the groove 32 slides with the support plate 33. The connecting shaft 34 is arranged at the bottom of the guide seat 30, and the outer periphery of the connecting shaft 34 is provided with bristles 35; the pneumatic assembly includes an air storage pipe 23, a second air pipe 25, a second air cylinder 27 and a first ring member 28. The air storage pipe 23 is provided with a first solenoid valve 24, the second air cylinder 27 is provided with a second solenoid valve 26, the second air pipe 25 is located between the first solenoid valve 24 and the second solenoid valve 26, and the first ring member 28 is arranged at the end of the second air cylinder 27.

[0024] Specifically, such as Figure 2 、 Figure 3 and Figure 4As shown, two inlet valves 12 and two outlet valves 13 are provided, one at each end of the first air cylinder 11. Both inlet valves 12 and outlet valves 13 are one-way valves. One end of a first air pipe 14 is connected to the outlet valve 13 near the third plate 8, and the other end is connected to the pipe body 15. Multiple air holes 18 are provided, evenly spaced along the axial direction of the pipe body 15. The pipe body 15 is located below the third plate 8, with a connecting rope 17 between the two. A sliding rod 16 is fixedly connected to the bottom of the third plate 8, which is arranged along the axial direction of the pipe body 15 and slides in engagement with the other. The drill bit 10 is arranged parallel to the pipe body 15. A piston is installed in the first air cylinder 11. When the third plate 8 moves downward, the gas below the piston is squeezed out through the outlet valve 13 at the lower end of the first air cylinder 11. Simultaneously, under the action of negative pressure, the gas enters the space above the piston through the inlet valve 12 at the upper end of the first air cylinder 11.

[0025] Specifically, such as Figure 2 、 Figure 3 and Figure 4As shown, the first gas cylinder 11 is connected to the gas storage pipe 23 through the gas outlet valve 13 near the first plate body 4. The first solenoid valve 24 is fixedly connected to the bottom of the gas storage pipe 23, and the gas storage pipe 23 is fixedly connected to the bottom of the first plate body 4. The second gas cylinder 27 is arranged parallel to the connecting rod 6 and the two are fixedly connected. The second solenoid valve 26 is fixedly connected to the top of the second gas cylinder 27. The two ends of the second gas pipe 25 are connected to the first solenoid valve 24 and the second solenoid valve 26 respectively. The gas storage pipe 23 and the second gas cylinder 27 are both small in size. This design can increase the gas pressure inside them. When the first solenoid valve 24 is opened, the gas in the gas storage pipe 23 flows along the second gas pipe 25 into the second gas cylinder 27. A piston is provided in the second gas cylinder 27. The piston moves under the gas pressure, further driving the movement of the first annular member 28. The first annular member 28 and the second annular member 29 are coaxially arranged. A plurality of guide assemblies are provided, evenly spaced around the second annular member 29. A ball bearing 38 is disposed on the top of the guide seat 30. The ball bearing 38 rolls against the first annular member 28. The driven gear 22 rotates, causing the support plate 33 to drive the guide seat 30 to rotate about the driven gear 22. The ball bearing 38 rolls against the first annular member 28, minimizing friction. The upper end of the support plate 33, near the second annular member 29, is tilted. A magnet is disposed on the side of the support plate 33, away from the tilt. The guide seat 30 is made of ferromagnetic metal. As the guide seat 30 moves downward, it moves along the tilted side of the support plate 33 toward the center of the second annular member 29, bringing the plurality of connecting shafts 34 closer together and allowing the connecting shafts 34 to pass through the drill holes in the circuit board. As the guide seat 30 moves upward, the magnet attracts the guide seat 30, forcing it to adhere to the tilted side of the support plate 33, separating the plurality of guide seats 30 and preventing them from obstructing the downward movement of the drill bit 10. The support plate 33 is fixedly connected to the top of the driven gear 22, and the guide groove 31 is arranged along the radial direction of the second annular member 29. The elastic telescopic assembly includes a second telescopic member 36 and an elastic member 37. The lower ends of the second telescopic member 36 and the elastic member 37 are both fixedly connected to the top of the driven gear 22, the upper end of the second telescopic member 36 is fixedly connected to the second annular member 29, and the upper end of the elastic member 37 is fixedly connected to the upper end of the second telescopic member 36. The elastic telescopic assembly provides the power for the upward and resetting movement of the second annular member 29.

[0026] Specifically, such as Figure 1 and Figure 4As shown, the bristles 35 are of an arc-shaped structure, with both ends fixedly connected to the surface of the connecting shaft 34. Both ends of the bristles 35 are fixed to the connecting shaft 34. When the device is in operation, the connecting shaft 34 rotates around the driven gear 22. The advantage of fixing both ends is that the bristles 35 are more secure, making the bristles 35 less susceptible to centrifugal force and scraping or collision with the hole wall, which could cause the bristles 35 to detach from the connecting shaft 34. Circular through-holes 39 are provided on the second plate 5 and the driven gear 22. The through-holes 39 facilitate the passage of the drill bit 10 and the connecting shaft 34. A waste trough 40 is provided on the base 1. The waste trough 40 is used to receive fallen debris for subsequent cleaning.

[0027] In summary, the present embodiment provides a punching device for processing a circuit board. When in operation, the circuit board is placed on the base 1, the cleaning part is moved to the processing station through the three-axis module 3, the second plate body 5 presses the circuit board, the driving member 9 is started, and the drill bit 10 is driven to rotate. At the same time, the transmission shaft 20 is driven to rotate through the transmission assembly 19, and the driving gear 21 and the driven gear 22 are further driven to rotate. When drilling, the first telescopic member 7 pushes the third plate body 8 to move downward, so that the drill bit 10 moves downward, and the drill bit 10 passes through the driven gear. The wheel 22 and the through hole 39 on the second plate 5 are used to drill holes in the circuit board. During the downward movement of the third plate 8, the gas below the piston in the first cylinder 11 enters the tube body 15 along the first air pipe 14 from the outlet valve 13 at the lower end and flows out from the air hole 18. The gas flows and sweeps the drill bit 10, blowing off the debris attached to the drill bit 10. During the movement of the piston of the first cylinder 11, the air inlet valve 12 at its upper end is opened under the action of negative pressure, and the gas enters the first cylinder 11. The gas is above the piston. After the drill bit 10 penetrates the circuit board, , the first telescopic member 7 drives the third plate 8 to move upward and reset. At this time, the piston of the first air cylinder 11 moves upward, so that the gas in the first air cylinder 11 passes through the air outlet valve 13 at the upper end, forcing the gas into the air storage pipe 23. Then, the first solenoid valve 24 is opened. Since the internal space of the air storage pipe 23 is small, the gas pressure is relatively large. Therefore, the gas in the air storage pipe 23 flows along the second air pipe 25 into the second air cylinder 27, causing the piston in the second air cylinder 27 to move downward, and the second annular member 29 and the guide seat 30 are driven downward through the first annular member 28. The guide seat 30 moves toward the center of the second annular member 29 along the inclined portion of the support plate 33, so that the connecting shaft 34 can pass through the hole on the circuit board. At the same time, the support plate 33 rotates with the driven gear 22, thereby causing the guide seat 30 and the connecting shaft 34 to rotate around the driven gear 22. The bristles 35 continuously scrape the hole wall to scrape off the debris. Finally, the first solenoid valve 24 is closed, and the second solenoid valve 26 is opened to release the excess gas in the second air cylinder 27. The elastic telescopic assembly then lifts the first annular member 28 and the second annular member 29.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
