Description

Technical Field

[0001] This invention relates to the field of circuit board processing technology, and more specifically, to a circuit board through-hole device. Background Technology

[0002] In the field of electronics manufacturing, circuit boards are the basic components of various electronic devices, and their processing quality directly affects the performance and reliability of electronic products. Circuit board perforation is one of the key processes in circuit board manufacturing. The accuracy and quality of perforation play a decisive role in subsequent component installation, circuit connection, and the realization of the overall circuit function.

[0003] A circuit board drilling device is disclosed in CN222200888U, comprising a base plate, a top plate connected to the base plate via a support column, a lead screw rotatably mounted on the base plate, an internal thread block threaded onto the lead screw, a first sliding rod installed between the base plate and the top plate, a first sliding sleeve installed on one side of the internal thread block, a first mounting bracket installed on the other side of the internal thread block, the first sliding sleeve slidably fitted onto the first sliding rod, a rectangular limiting frame installed at the end of the first mounting bracket, and a limiting groove formed at the bottom of the top plate. In this invention, the device uses a drill bit to drill holes in the circuit board from bottom to top. Circuit board debris generated during drilling falls downwards under its own weight, preventing it from falling onto the circuit board and causing dirt or damage. This allows the circuit board debris generated during drilling to automatically fall downwards.

[0004] Currently, various circuit board through-hole devices exist on the market, but some devices have shortcomings in the through-hole process. Some traditional through-hole devices lack effective detection and adjustment mechanisms, often requiring extensive manual debugging and adjustment when dealing with circuit boards of different thicknesses. This manual debugging method is not only extremely inefficient and time-consuming, but also prone to human error during operation. When dealing with circuit boards of significantly different thicknesses, the through-hole effect is difficult to guarantee. When the circuit board is thin, over-adjustment may cause the drill bit to penetrate the circuit board, damaging it and rendering it unusable. Conversely, when the circuit board is thick, insufficient adjustment may prevent the drill bit from fully penetrating the circuit board, resulting in a hole that cannot be drilled through, affecting the installation of subsequent components and the connection of circuits, thus seriously affecting the quality and overall performance of the circuit board. Therefore, we propose a circuit board through-hole device. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a circuit board through-hole device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a circuit board perforation device, comprising an operating table device and a perforation mechanism, wherein a detection and adjustment component is provided inside the operating table device, and the perforation mechanism is disposed on top of the detection and adjustment component; The detection and adjustment components include a fixed base installed inside the operating table device and a mounting bracket installed on one side of the operating table device. A spring is installed inside the fixed base, and a connecting rod is located inside the fixed base and within the spring. A positioning plate is installed on the top of the connecting rod, and the top of the spring is connected to the positioning plate. A rubber pad is embedded in the bottom of the positioning plate. A rack and pinion are connected to the front of the mounting bracket, and a gear is rotatably connected to the front of the mounting bracket. A mounting box is installed on the outer side of the mounting bracket. Two symmetrical support plates are installed inside the mounting box. A terminal block and a metal rod are shared inside the two support plates. A resistance wire is installed outside the terminal block, and a slider is installed outside the metal rod. A connecting bracket is installed on one side of the slider. A spring is installed on one side of the inner side of the mounting box. A lifting plate is installed on the bottom side of the two racks. A perforation mechanism is located on the top of the lifting plate, and a sliding groove is opened on the outer side of the mounting box.

[0007] Preferably, both the fixing base and the mounting bracket are provided in two sets, and the two sets of components are symmetrically distributed.

[0008] Preferably, the bottom end of the connecting rod is connected to rack one, the gear is located between rack one and rack two, and the teeth of the gear mesh with the teeth of rack one and rack two respectively.

[0009] Preferably, a connecting plate is installed on the outer side of both rack one and rack two, and two symmetrical connecting grooves are opened on the outer side of the mounting bracket, with the connecting plate slidably connected inside the connecting groove.

[0010] Preferably, the connecting frame is L-shaped and is located inside the slide groove.

[0011] Preferably, one end of the second spring is connected to the connecting frame, and one end of the connecting frame is connected to the first rack.

[0012] Preferably, an mounting cylinder is installed on the outside of the connecting rod, a finger plate is installed on the outside of the mounting cylinder, and a scale is installed on one side of the bottom of the fixing seat.

[0013] The technical effects and advantages of this invention are as follows: In use, the circuit board perforation device of this invention achieves precise adjustment of the height of the perforation mechanism through the detection and adjustment component. When the circuit board to be perforated is placed on the operating table device, the positioning plate is compressed downward by the circuit board, compressing the spring one. The connecting rod moves downward accordingly, which in turn drives the rack one to move downward. Since the gear meshes with rack one and rack two, the movement of rack one will cause the gear to rotate, thereby driving rack two to move upward. Finally, the lifting plate rises, bringing the perforation mechanism closer to the circuit board. This adjustment method based on gear and rack transmission can accurately adjust the perforation mechanism according to the actual thickness of the circuit board, ensuring the accuracy and quality of perforation and improving the product qualification rate.

[0014] In use, during the lifting process of the lifting plate, the connecting frame moves within the slide groove along with the movement of the rack, causing the slider to slide on the metal rod, changing the resistance value of the connected circuit, generating different electrical signals, and feeding them back to the control system. The control system can determine the position and status of the circuit board based on the electrical signals, further precisely controlling the thickness of the circuit board. At the same time, by setting two electrical signal detection points, it is possible to detect whether the device is in a horizontal state. If the signals at both ends differ significantly, it indicates that there may be a problem with the device, and the staff can check and repair it in time, avoiding the impact of the perforation effect due to the device not being horizontal, ensuring the stable operation of the device, and improving production efficiency and product quality.

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

[0023] As attached Figures 1-6 The circuit board perforation device shown includes an operating table device 1 and a perforation mechanism 3. The operating table device 1 is equipped with a detection and adjustment component 2, and the perforation mechanism 3 is located on top of the detection and adjustment component 2. The detection and adjustment assembly 2 includes a fixed base 21 installed inside the operating table device 1 and a mounting bracket 22 installed on one side of the operating table device 1. Both the fixed base 21 and the mounting bracket 22 are provided in two sets, and the two sets of components are symmetrically distributed. A spring 23 is installed inside the fixed base 21. A connecting rod 24 is installed inside the fixed base 21 and inside the spring 23. A positioning plate 25 is installed on the top of the connecting rod 24. The top of the spring 23 is connected to the positioning plate 25. A rubber pad 26 is embedded in the bottom of the positioning plate 25. The front side of the mounting bracket 22 is connected to rack 1 27 and rack 29 respectively. The bottom end of the connecting rod 24 is connected to rack 1 27. A gear 28 is rotatably connected to the front side of the mounting bracket 22. Gear 28 is located between rack 1 27 and rack 29, and the teeth of gear 28 mesh with the teeth of rack 1 27 and rack 29 respectively. A connecting plate 210 is installed on the outer side of rack 1 27 and rack 29. Two symmetrical connecting grooves 211 are opened on the outer side of the mounting bracket 22. The connecting plate 210 slides. Connected inside the connecting slot 211, a mounting box 212 is installed on the outer side of the mounting bracket 22. Inside the mounting box 212 are two symmetrical support plates 213. Both support plates 213 share a common internal terminal 214 and a metal rod 215. A resistance wire 216 is installed outside the terminal 214, and a slider 217 is installed outside the metal rod 215. A connecting bracket 218 is installed on one side of the slider 217. A spring 219 is installed on one side of the inside of the mounting box 212. The bottom of the two racks 29... A lifting plate 220 is installed on both sides. The perforation mechanism 3 is located on the top of the lifting plate 220. A slide groove 224 is opened on the outside of the mounting box 212. The connecting frame 218 is "L" shaped and is located inside the slide groove 224. One end of the second spring 219 is connected to the connecting frame 218. One end of the connecting frame 218 is connected to the rack 27. An mounting cylinder 221 is installed on the outside of the connecting rod 24. A finger plate 222 is installed on the outside of the mounting cylinder 221. A scale 223 is installed on one side of the bottom of the fixed seat 21.

[0024] When the circuit board through-hole device is in its initial state, the operating table device 1 is placed stably. Two sets of fixed seats 21 and mounting brackets 22 are symmetrically distributed inside and on one side of the operating table device 1. The spring 23 inside the fixed seat 21 is in a naturally extended state. The connecting rod 24 is inside the spring 23. The positioning plate 25 at its top is at a certain height under the support of the spring 23. The rubber pad 26 at the bottom of the positioning plate 25 can play a buffering and protective role.

[0025] One end of spring 219 is connected to the connecting frame 218. Spring 219 will deform. When it is necessary to reset or make fine adjustments, the elastic force of spring 219 will act on the connecting frame 218, so that the slider 217 returns to the appropriate position, ensuring the stability of the resistance value and the accuracy of the adjustment, thereby ensuring that the entire detection and adjustment assembly 2 can work normally and achieve precise control of the perforation mechanism 3. Operators can intuitively understand the moving distance of the connecting rod 24 by observing the position of the finger plate 222 on the scale 223, and thus grasp the descent height of the positioning plate 25 and the thickness of the circuit board to meet different perforation requirements.

[0026] Working principle of the invention: Both the operating table device 1 and the perforation mechanism 3 are existing structures as disclosed in CN222200888U. The operating table device 1 includes: a base plate, a support column, a top plate, a first motor, a lead screw, an internal thread block, a first slide rod, a first sliding sleeve, a first mounting bracket, a bearing, a rectangular limiting frame, a limiting groove, a second slide rod, a second sliding sleeve, and a second mounting bracket. The perforation mechanism 3 includes: an electric telescopic rod, a second motor, a drill bit, and a mounting plate. Specific implementation details are not described in detail here. The fixed base 21 is installed inside the rectangular limiting frame set inside the operating table device 1. The mounting bracket 22 is installed at the bottom of the rectangular limiting frame set inside the operating table device 1. The rubber pad 26 is located at the top of the circuit board, and the circuit board is located at the top of the rectangular limiting frame. The circuit board to be drilled is placed on the bottom of the rectangular limiting frame inside the operating table device 1. When the circuit board is fixed and drilled by the operating table device 1, the positioning plate 25 moves upward and is compressed, which in turn compresses the two springs 23. The connecting rod 24 moves downward accordingly until the rubber pad 26 is in contact with the circuit board, thus fixing the circuit board. At this time, since the bottom end of the connecting rod 24 is connected to the rack 27, the rack 27 will move downward with the connecting rod 24. The gear 28 is located between the rack 27 and the second rack 29, and the teeth of the gear 28 mesh with the teeth of the rack 27 and the second rack 29 respectively. When the rack 27 moves downward, the gear 28 will rotate, thereby driving the second rack 29. As racks 29 move upwards, connecting plate 210 slides within connecting groove 211, providing guidance and stability to ensure the smooth and accurate movement of racks 27 and 29. A lifting plate 220 is installed on one side of the bottom of both racks 29. When racks 29 move upwards, they drive the lifting plate 220 upwards. This upward movement of the lifting plate 220 brings the perforation mechanism 3 closer to the circuit board, allowing adjustment of the perforation mechanism 3 based on the circuit board's thickness and placement. The rubber pad 26 at the bottom of positioning plate 25 presses against the circuit board to detect thickness changes, causing the height of the perforation mechanism 3 to follow the changes. Then, the perforation mechanism 3 performs the drilling operation. During the ascent of the lifting plate 220, since the connecting frame 218 is "L" shaped and located inside the slide groove 224, and one end of the connecting frame 218 is connected to the rack 27 and the other end is connected to the slide plate 217, the movement of the rack 27 will drive the connecting frame 218 to move within the slide groove 224, thereby causing the slide plate 217 to slide on the metal rod 215. The movement of the slide plate 217 will change the resistance value of the circuit and generate different electrical signals. These electrical signals can be fed back to the control system. The control system judges the position and status of the circuit board based on the electrical signals, further accurately controls the thickness of the circuit board, and the setting of the two electrical signals can detect whether the device is in a horizontal state. If the signals at both ends differ greatly, it indicates that there is a problem with the device, and the staff can check and repair it in time to avoid affecting the perforation effect. After the subsequent drilling is completed, the positioning plate 25 is reset by the setting of two springs 23. At this time, the lifting plate 220 is also reset, which facilitates the subsequent drilling work on the next circuit board.
