Description

Technical Field

[0001] This invention relates to the field of electronic product manufacturing and processing technology, and in particular to a drilling device for electronic product components. Background Technology

[0002] Drilling is an indispensable and crucial step in the production process of metal-based circuit boards. Due to the multi-layered structure of metal-based circuit boards, the connections between circuit layers and the positioning during assembly all require drilling. The drilled holes serve different purposes. Some holes are used to create vias; in a circuit board, vias act like bridges, and by plating them with copper, stable electrical connections are achieved between circuit layers, ensuring smooth current flow, which is extremely critical for the normal operation of the circuit board. Other holes are used to create positioning holes. Positioning holes are crucial at every stage of circuit board production, from manufacturing and testing to final assembly. They provide precise positioning references for each step, allowing for accurate installation of components and significantly improving the production quality and assembly efficiency of the circuit board.

[0003] However, due to the extremely smooth surface of metal-based circuit boards, drilling presents numerous challenges. The smooth surface makes it difficult for the drill bit to maintain a stable position upon contact, easily leading to deviation and causing the drilled hole to deviate from the intended location. If the hole is misaligned, the drill bit is likely to scratch the surface of the metal-based circuit board, leaving scratches. Even more seriously, if the drill bit deviates excessively, it may even directly cut through the copper layer in the metal-based circuit board, rendering the entire board unusable. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of drill bit deviation and difficulty in precise positioning during the drilling process of metal-based circuit boards in the prior art, and to propose a drilling device for electronic product manufacturing components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a component drilling device for electronic product manufacturing, comprising a mounting base, an aluminum sheet, and a metal-based circuit board.

[0010] Preferably, the drilling mechanism includes a first electric telescopic rod fixedly installed on the top wall of the first housing, the working end of the first electric telescopic rod is vertically downward and fixedly installed with a motor, and the output end of the motor is fixedly installed with a drill bit.

[0011] Preferably, the drive assembly includes a sliding rod slidably mounted between two sets of mounting plates, a second electric telescopic rod fixedly mounted between the sliding rod and the second hollow rod, and a third telescopic plate fixedly mounted at both ends of the sliding rod, with the lower ends of both sets of the third telescopic plates rotatably connected to the roller.

[0012] Preferably, a sliding groove is movably installed below the mounting plate. The inner bottom wall of the sliding groove first slopes downward from one end of the sliding groove near the second hollow rod to the other end, and then turns to be horizontal. The left and right ends of the roller are rotatably installed in the corresponding sliding grooves. An electric telescopic block is fixedly installed between the upper surface of the sliding groove and the mounting plate.

[0013] Preferably, a first rubber ring is bonded inside the third housing, a lifting device is provided between the first rubber ring and the inner top wall of the third housing, a second rubber ring is movably connected to the outer side of the second hollow rod, and a sliding device is provided between the second rubber ring and the second hollow rod.

[0014] Preferably, a first hollow rod communicating with the second hollow rod is fixedly installed at the upper end of the third housing. A blowing device is fixedly installed on one side of the first hollow rod and a second dust-collecting device is fixedly installed on the other side of the third housing.

[0015] Preferably, the movable plate is slidably connected to the inner wall of the second housing, and a fixed plate is fixedly installed inside the second housing below the movable plate.

[0016] Preferably, the third housing is equipped with multiple cooling fans to dissipate heat from inside the third housing to the outside.

[0017] Compared with existing technologies, the advantages of this invention are:

[0018] 1. This application utilizes the high hardness of aluminum sheets to provide stable support for the drill bit, ensuring vertical feed accuracy. Combined with the upper and lower pressing frame clamping design, this fully exposes the metal-based circuit board, reducing the risk of localized thermal deformation. The roller system employs a combination of downward pressing and horizontal rolling, along with viscous thermally conductive silicone, effectively eliminating aluminum sheet wrinkles and enhancing the flatness of the contact surface. A telescopic rubber ring further secures the aluminum sheet, and the elastic pressure distribution prevents rebound, forming a multi-level flatness protection mechanism. The structural design incorporates dynamic clamping and a movable drilling unit, achieving precise positioning while optimizing heat dissipation paths by intermittently exposing the processed area.

[0019] 2. In this application, the high thermal conductivity of the aluminum sheet itself allows for rapid heat dissipation during drilling, reducing thermal damage to the substrate and drill bit. During operation, the dynamic switching of the clamping positions directly exposes the processed area, accelerating heat diffusion to the environment. When the roller retracts, the thermally conductive silicone rolls in contact with the aluminum sheet, specifically absorbing residual heat around the hole and forming a secondary heat dissipation path. Combined with the intermittent processing rhythm, this avoids the accumulation of localized, sustained high temperatures. The three-stage heat transfer channel of aluminum sheet-silicone-environment significantly improves heat dissipation efficiency, keeping the temperature within the material's tolerance range and ensuring processing stability.

[0020] 3. In this application, the annular blowing and suction system uses a downward-sloping airflow to directionally remove chips from the hole, and, in conjunction with the bidirectional dust collection device, achieves full-space coverage, eliminating chip residue. The hollow rod structure physically isolates the splash path, preventing scratches on the aluminum sheet surface. The moving plate and airbag buffer system effectively absorb drill bit impact vibrations, reducing the risk of resonance in unsupported areas. The sticky contact method of the rollers simultaneously cleans surface dust during the leveling process, and, combined with the flexible fixation of the rubber rings, forms a complete surface protection system from processing to fixing.

[0021] In summary, this application achieves multi-dimensional breakthroughs in precision, heat dissipation, and cleanliness through structural innovation. The aluminum sheet and dynamic clamping structure lay the physical foundation for machining precision, the multi-stage heat dissipation system constructs a three-dimensional thermal management network from conduction to convection, and the combined blowing and suction and buffering design ensures the cleanliness of the machining environment and the reliability of the equipment.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figures 1 to 11A component drilling device for electronic product manufacturing includes a mounting base 1. A first pressing frame 3 is movably mounted inside the mounting base 1, and a second pressing frame 7 is fixedly mounted. The second pressing frame 7 is located directly below the first pressing frame 3, and there is a certain gap between the second pressing frame 7 and the first pressing frame 3. This gap is used to place an aluminum sheet 6 and a metal-based circuit board 13. During placement, the aluminum sheet 6 adheres to the upper surface of the metal-based circuit board 13. First sliding grooves are formed around the upper surface of the first pressing frame 3, and a first electric sliding block 4 is slidably mounted inside the first sliding groove. The first electric sliding block 4 faces... A first telescopic plate 5 is fixedly installed on one side of the vertical central axis of the mounting base 1. The working ends of multiple first telescopic plates 5 are fixedly connected to the first housing 2. Second sliding grooves are formed around the lower surface of the second pressing frame 7. Second electric sliding blocks 8 are slidably installed inside the second sliding grooves. Second telescopic plates 9 are fixedly installed on the side of the second electric sliding blocks 8 facing the vertical central axis of the mounting base 1. The working ends of multiple second telescopic plates 9 are fixedly connected to the second housing 10. The second housing 10 is located directly below the first housing 2, and there is a gap between them for placing the aluminum sheet 6 and the metal-based circuit board 13. Under the action of the first electric sliding block 4, the first telescopic plate 5, the second electric sliding block 8, and the second telescopic plate 9, the horizontal positions of the first housing 2 and the second housing 10 can be freely adjusted, thus facilitating drilling operations at different points on the metal-based circuit board 13.

[0036] A first electric telescopic rod 12 is fixedly installed on the inner top wall of the first housing 2. The working end of the first electric telescopic rod 12 is vertically downward and fixedly installed with a motor 14. A drill bit 15 is fixedly installed at the output end of the motor 14. A third housing 21 is fixedly installed at the lower part of the interior of the first housing 2. A first hollow rod 18 communicating with the interior is fixedly installed at the middle position of the upper end of the third housing 21. A second hollow rod 24 connected to the first hollow rod 18 is fixedly installed inside the third housing 21. The lower end of the drill bit 15 extends to the inside of the first hollow rod 18 and can move freely up and down in the first hollow rod 18. A blowing device 17 is fixedly installed on one side of the first hollow rod 18 and fixedly installed on the third housing 21. A second dust suction device 16 is fixedly installed on the other side of the first hollow rod 18 and fixedly installed on the third housing 21. An annular blowing pipe 19 communicating with the interior is fixedly installed on the outer side of the first hollow rod 18. The output end of the blowing device 17 is connected to the upper side of the annular blowing pipe 19. The input end of the second dust suction device 16 is connected to the lower side of the annular dust suction pipe 20. When the air blowing device 17 and the second dust suction device 16 are running, the gas blown out by the air blowing device 17 can flow inside the annular air blowing pipe 19. The downward-sloping airflow blows up the chips formed by drilling, and then the chips are sucked into the second dust suction device 16 by the annular dust suction pipe 20.

[0037] A first rubber ring 23 is bonded inside the third housing 21. A lifting device (not shown in the figure) is provided between the first rubber ring 23 and the inner top wall of the third housing 21. The lifting device is prior art and is used to allow the first rubber ring 23 to move up and down slightly inside the third housing 21. A second rubber ring 25 is movably connected to the outer side of the second hollow rod 24. A sliding device (not shown in the figure) is provided between the second rubber ring 25 and the second hollow rod 24. The sliding device is prior art and is used to allow the second rubber ring 25 to move up and down slightly outside the second hollow rod 24. Multiple sets of smoothing mechanisms are arranged in a circular array at equal angles inside the first rubber ring 23. Each set of smoothing mechanisms includes two sets of mounting plates 26 fixedly installed on the inner top wall of the third housing 21 and arranged in parallel. A sliding rod 28 is slidably installed between the two sets of mounting plates 26. The sliding rod 28 is connected to the second hollow rod 24. A second electric telescopic rod 27 is fixedly installed between the two sets of mounting plates 26. The second electric telescopic rod 27 is used to drive the sliding rod 28 to move between the two sets of mounting plates 26. A third telescopic plate 30 is fixedly installed at both ends of the sliding rod 28. A roller 29 is rotatably installed between the two sets of third telescopic plates 30. The surface of the roller 29 is coated with thermally conductive silicone. A sliding groove 32 is movably installed below the mounting plate 26. The inner bottom wall of the sliding groove 32 first slopes downward from one end of the sliding groove 32 near the second hollow rod 24 to the other end, and then turns to be horizontal. The left and right ends of the roller 29 are rotatably installed in the corresponding sliding groove 32. An electric telescopic block 31 is fixedly installed between the upper surface of the sliding groove 32 and the mounting plate 26. The electric telescopic block 31 is used to drive the sliding groove 32 to move up and down slightly inside the mounting plate 26. The sliding groove 32 is made of rigid material and drives the roller 29 to move synchronously while moving up and down.

[0038] To further improve the heat dissipation performance of the device, multiple cooling fans 22 are installed on the third housing 21 to dissipate the heat inside the third housing 21 to the outside.

[0039] A movable plate 33 is slidably mounted on the upper part of the second housing 10. Below the movable plate 33, a fixed plate 35 is fixedly mounted inside the second housing 10. An annular airbag 34 is placed on the fixed plate 35. A through hole is formed in the middle of the movable plate 33. A first vacuuming device 11 is detachably mounted on the lower end of the second housing 10. A telescopic tube 36 is fixedly connected to the input end of the first vacuuming device 11, and the upper end of the telescopic tube 36 communicates with the through hole. When the drill bit 15 drills through the metal-based circuit board 13, the first vacuuming device 11 below will suck up the chips through the telescopic tube 36, preventing the chips from accumulating and clogging in the through hole.

[0040] The specific working principle of this invention is as follows: First, the metal-based circuit board 13 to be drilled is placed on the second pressing frame 7. Then, the aluminum sheet 6 is placed on the metal-based circuit board 13 and aligned. Subsequently, the first pressing frame 3 is slowly pressed down, so that the aluminum sheet 6 and the metal-based circuit board 13 are clamped by the first pressing frame 3 and the second pressing frame 7. The aluminum sheet 6 is placed on the metal-based circuit board 13. The high hardness of the aluminum sheet 6 helps to ensure that the drill bit 15 feeds stably in the vertical direction, thereby obtaining more accurate hole positions and diameters. The aluminum sheet 6 also has good thermal conductivity, which can quickly conduct away the heat generated during the drilling process, preventing the metal-based circuit board 13 and the drill bit 15 from being damaged due to overheating. Then, the extension and retraction of the first telescopic plate 5 and the second telescopic plate 9 drives the first housing 2 and the second housing 10 to move. After moving to the appropriate position, the first electric telescopic rod 12 extends, and at the same time, the motor 14 starts, thereby driving the drill bit 15 to drill holes in the metal-based circuit board 13. In typical drilling devices, the lower mounting base often only provides support, resulting in poor ventilation and heat dissipation under the metal-based circuit board 13. Over time, this can easily lead to heat deformation of the metal-based circuit board 13. However, by using the first pressing frame 3 and the second pressing frame 7 to clamp the circuit board at appropriate positions and drill holes, the surrounding metal-based circuit board 13 can be directly exposed, increasing the heat dissipation area. After drilling is completed in one area, the first housing 2 and the second housing 10 will move to other positions to continue drilling, exposing the previously drilled area and allowing heat to be more easily transferred from the circuit board to the external environment.

[0041] Four rollers 29 are evenly distributed around the drill bit 15. This arrangement ensures that the aluminum sheet 6 is subjected to uniform force in all directions when the rollers 29 are used to smooth it. Before the drill bit 15 drills downward, the second electric telescopic rod 27 is activated, which drives the rollers 29 forward to smooth the aluminum sheet 6 via the sliding rod 28 and the third telescopic plate 30. The smoothing operation makes the surface of the aluminum sheet 6 smoother and ensures good contact with the metal-based circuit board 13, improving drilling accuracy. The rollers 29 are coated with adhesive thermally conductive silicone, which ensures that the rollers 29 first stick to the aluminum sheet 6 during rolling, and then pull the aluminum sheet 6 during rolling. This process helps to eliminate wrinkles, ripples or uneven parts on the aluminum sheet 6, so as to effectively hold the aluminum sheet 6 without damaging its surface. In addition, during the rolling of the rollers 29 in the groove 32, the rollers 29 will follow the shape of the groove 32, first pressing and rolling downward at an angle for a short distance, and then turning to roll horizontally. When the roller 29 first begins to roll, the downward-sloping pressing motion helps to better press the aluminum sheet 6, especially for areas with uneven surfaces or small protrusions. This pressing method increases the contact area and adhesion between the roller 29 and the aluminum sheet 6, laying a good foundation for subsequent rolling and smoothing. After completing the downward-sloping pressing, the roller 29 switches to horizontal rolling, evenly stretching and smoothing the surface of the aluminum sheet 6 through rolling. The horizontal rolling path ensures the uniformity and continuity of the processing, avoiding excessive force or insufficient processing in certain areas. After the roller 29 has rolled, the smoothed aluminum sheet 6 is fixed using the first rubber ring 23 and the second rubber ring 25. The rubber material has excellent elasticity and cushioning properties, providing stable support during the pressing process and ensuring that the aluminum sheet 6 receives uniform pressure distribution. This step helps to consolidate the smoothing effect and prevent the aluminum sheet 6 from rebounding or deforming during subsequent processing. After the drill bit 15 finishes drilling, the first rubber ring 23 and the second rubber ring 25 are lifted, and the electric telescopic block 31 is retracted so that the roller 29 makes slight contact with the aluminum sheet 6 without excessive compression. Then, the second electric telescopic rod 27 is activated so that the roller 29 rolls back. When it rolls on the aluminum sheet 6, the thermally conductive silicone on the roller 29 can quickly transfer the heat from the aluminum sheet 6 to the roller 29, thereby removing the heat generated during the drilling process. In particular, it dissipates heat from the areas around the hole where the heat is too high, which helps to reduce heat accumulation.

[0042] When the drill bit 15 drills downwards, the air blowing device 17 is activated, blowing air into the first hollow rod 18 through the annular air blowing pipe 19. The downward-sloping airflow blows up the chips formed during drilling, which are then sucked into the second suction device 16 by the annular suction pipe 20. Because the airflow is downward-sloping, it can act more directly on the chips in the hole, using strong force to blow the chips out of the hole, and then suck them away by the annular suction pipe 20. When the drill bit 15 drills out of the metal base circuit board 13, the first suction device 11 below will also suck away the chips through the telescopic pipe 36. This two-way chip removal from both above and below can more effectively cover the entire drilling area, avoiding chip accumulation and blockage in the through hole. In addition, due to the presence of the first hollow rod 18 and the second hollow rod 24, the chips will not fly around and scratch the surface of the aluminum sheet 6, improving the drilling quality. In addition, the lower movable plate 33 and the annular airbag 34 can provide effective cushioning for the drill bit 15, reduce vibration and noise caused by impact during drilling, and reduce the impact force on the surrounding unsupported metal-based circuit board 13.
