Description

Technical Field

[0001] This utility model belongs to the field of copper clad laminate drilling technology, specifically a copper clad laminate drilling positioning device. Background Technology

[0002] Copper-clad laminate (CCL) is a basic material for circuit boards, made by pressing an insulating substrate and copper foil together with an adhesive. It is widely used in the manufacture of printed circuit boards (PCBs) and serves as a carrier for mounting electronic components and connecting circuits. During PCB manufacturing, CCL requires drilling, which is a key step in achieving electrical connections between layers of a multilayer board. On one hand, drilling is used to install the pins of through-hole components, ensuring mechanical fixation and electrical conductivity between the components and the circuit board. On the other hand, by drilling vias (through holes) in the CCL, circuit interconnection between different copper foil layers can be achieved, constructing a complete three-dimensional circuit network. In addition, drilling is also used to install screws and other fixing components, facilitating the installation and positioning of the circuit board in equipment.

[0003] For example, utility model patent CN218170676U discloses a copper-clad laminate drilling machine, including a main body. A column and a support plate are fixedly connected to the upper surface of the main body. A drill bit extension hole is opened at the center of the support plate. A crossbeam is fixed to the upper end of the column. A compression cylinder is installed inside the crossbeam. A motor is installed at the drive end of the compression cylinder. A drill bit is installed at the drive end of the motor. A fixing mechanism can fix the edge of the copper-clad laminate, thereby avoiding human pressure on the copper-clad laminate and reducing human operation errors. A recycling mechanism can suck the waste generated by drilling into the dust collection box for storage, preventing users from inhaling it.

[0004] However, in actual use, it was found that the conduit of the recycling mechanism in the device is only connected to the drill extension hole in the center of the tray. When the copper-clad laminate needs to be drilled in different areas away from the center, the debris generated by the drilling will be scattered around the drilling point. Since the conduit cannot cover the non-central area, a large amount of debris cannot be sucked in in time and is easy to accumulate on the tray surface or splash to the outside of the equipment, resulting in a significant reduction in dust collection efficiency. Therefore, a copper-clad laminate drilling positioning device is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a copper-clad laminate drilling positioning device in order to solve the problems mentioned above.

[0006] The technical solution adopted by this utility model is as follows: a copper-clad laminate drilling positioning device, including a base, an adjusting support fixedly installed on the top surface of the base, a drilling platform provided on the top surface of the adjusting support, and a clamping mechanism provided on the top surface of the drilling platform.

[0007] A bracket is fixedly installed on one side of the adjustable support. A U-shaped adjusting seat is fixedly installed at the end of the bracket away from the adjustable support. A mounting plate is provided on the front side of the U-shaped adjusting seat. An adjusting mechanism connected to the mounting plate is provided inside the U-shaped adjusting seat.

A drill rod is fixedly installed at the drive end of the second motor. Multiple movable support rods are movably installed through the top surface of one of the two motor support plates. A circular dust collection ring is fixedly installed at the bottom end of each of the multiple movable support rods. A dust collection hole is opened on the inner wall of the circular dust collection ring. A flexible dust collection pipe is fixedly installed on the outer surface of the dust collection hole. The end of the flexible dust collection pipe away from the dust collection hole is connected to an external dust collection mechanism. A return spring is provided on the outer surface of the movable support rod. The bottom end of the return spring is fixed to the top surface of the circular dust collection ring, and the top end of the return spring is fixed to the bottom surface of the motor support plate.

[0008] In a preferred embodiment, the clamping mechanism includes a fixed base, a bidirectional screw, a handwheel, and a limiting clamp. The fixed base is fixedly installed on the top surface of the drilling platform. The bidirectional screw is rotatably connected inside the fixed base through a bearing. One end of the bidirectional screw extends to the outside of the fixed base. The handwheel is fixedly installed at the end of the bidirectional screw extending outside the fixed base. The bidirectional screw has two threaded sections with opposite directions of rotation. The limiting clamp is threadedly connected to the two threaded sections with opposite directions of rotation of rotation.

[0009] In a preferred embodiment, the adjusting mechanism includes a lead screw, a threaded slide, and a motor. The lead screw is rotatably connected inside the U-shaped adjusting seat, and the threaded slide is threadedly connected to the outer surface of the lead screw.

[0012] In a preferred embodiment, a limit ring is fixedly installed on the outer surface of the movable support rod on the top surface of the motor support plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by adopting the above-mentioned solution, the drilling platform is moved in the X / Y axis direction by adjusting the left-right and front-back adjustment mechanisms at the top of the support. At the same time, the motor of the adjustment mechanism drives the lead screw, causing the threaded slide to move the mounting plate downward, which facilitates the drill rod to be aligned with the target drilling position. The second motor starts to press the drill rod down to drill. At this time, the circular dust collection ring moves down synchronously with the mounting plate and the motor support plate, and the rubber pad adheres to the surface of the plate to form a seal. Then, the dust collection hole sucks the debris into the external dust collection mechanism through the soft dust collection pipe. After drilling is completed, the drill rod moves up, and the return spring pushes the circular dust collection ring to return to its original position. This device can accurately position the copper-clad board through the clamping mechanism. With the linkage adjustment of the adjustment mechanism and the drill rod, the drilling position can be accurately controlled. At the same time, the circular dust collection ring collects debris in real time, improving the debris collection effect. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] refer to Figures 1-4As shown, a copper-clad laminate drilling and positioning device includes a base 1, an adjusting support 2 fixedly installed on the top surface of the base 1, a drilling platform 3 on the top surface of the adjusting support 2, and a clamping mechanism 4 on the top surface of the drilling platform 3. A left-right and front-back adjustment mechanism, consisting of a drive motor, a lead screw, a slider, and a limiting rod, is provided on the top surface of the adjusting support 2. The motor drives the lead screw to rotate, causing the slider to adjust the planar position of the drilling platform 3 under the guidance of the limiting rod. This allows for precise control of the copper-clad laminate's displacement in the X / Y axis directions, facilitating alignment of the drilling point directly below the drill rod 11. The drilling platform 3 provides a flat base for the copper-clad laminate, and the clamping mechanism 4, in conjunction with the platform, positions and fixes the laminate, ensuring stable position during drilling and effectively improving the convenience and positioning accuracy of the drilling operation.

[0022] refer to Figures 1-4 As shown, the clamping mechanism 4 includes a fixed base 401, a bidirectional screw 402, a handwheel 403, and a limiting clamping plate 404. The fixed base 401 is fixedly installed on the top surface of the drilling table 3. The bidirectional screw 402 is rotatably connected to the inside of the fixed base 401 through a bearing. One end of the bidirectional screw 402 extends to the outside of the fixed base 401. The handwheel 403 is fixedly installed at the end of the bidirectional screw 402 extending to the outside of the fixed base 401. The bidirectional screw 402 has two threaded sections with opposite directions of rotation. A limiting clamping plate 404 is threadedly connected at the two threaded sections with opposite directions of rotation. A positioning mark is installed in the middle of the side of the fixed seat 401 near the copper-clad laminate. When the copper-clad laminate is placed on the drilling table 3, the operator can bring the center of the side of the copper-clad laminate as close as possible to the positioning mark. This makes it easy for the operator to rotate the handwheel 403 to drive the bidirectional screw 402 to rotate. The two reverse threads drive the limiting clamping plate 404 to move towards the center synchronously, realizing the rapid positioning and clamping of the copper-clad laminate. The clamping force is uniform, avoiding deformation of the board due to uneven force.

[0023] refer to Figures 1-4 As shown, a bracket 5 is fixedly installed on one side of the adjusting support 2, and a U-shaped adjusting seat 6 is fixedly installed at the end of the bracket 5 away from the adjusting support 2. A mounting plate 7 is provided on the front side of the U-shaped adjusting seat 6, and an adjusting mechanism 8 connected to the mounting plate 7 is provided inside the U-shaped adjusting seat 6. Through the adjusting mechanism 8, the mounting plate 7 can be driven to move laterally within the U-shaped adjusting seat 6, which facilitates the subsequent adjustment of the horizontal position of the drilling mechanism, realizes the drilling positioning of different areas of the copper-clad laminate, and adapts to diverse drilling needs.

[0024] refer to Figures 1-4As shown, the adjustment mechanism 8 includes a lead screw 801, a threaded slide 802, and a motor 803. The lead screw 801 is rotatably connected inside the U-shaped adjustment seat 6, and the threaded slide 802 is threadedly connected to the outer surface of the lead screw 801. The motor 803 is fixedly installed on the top surface of the U-shaped adjustment seat 6, and the drive end of the motor 803 extends into the interior of the U-shaped adjustment seat 6 and is fixed to the top of the lead screw 801. The motor 803 can drive the lead screw 801 to rotate, and the threaded slide 802 moves linearly along the lead screw 801, driving the mounting plate 7 to be precisely positioned, realizing automated control of the lateral displacement of the drill rod 11, improving the accuracy and efficiency of drilling position adjustment. A limit rod is installed inside the U-shaped adjustment seat 6. The limit rod passes through the top surface of the threaded slide 802 and is fixed to the inner top and bottom surfaces of the U-shaped adjustment seat 6, so that the threaded slide 802 will not rotate when moving.

[0025] refer to Figures 1-4 As shown, two motor support plates 9 are fixedly installed on the front side of the mounting plate 7, and a second motor 10 is fixedly installed on the top surface of each of the two motor support plates 9. A drill rod 11 is fixedly installed on the drive end of the second motor 10. The second motor 10 can drive the drill rod 11 to rotate at high speed to realize the drilling operation on the copper-clad laminate. The setting of the two motor support plates 9 can enhance the stability of the drill rod 11 installation and ensure the verticality and rigidity of the drill rod 11 during the drilling process.

[0026] refer to Figures 1-4 As shown, multiple movable support rods 12 are movably mounted on the top surface of one of the two motor support plates 9, and a circular suction ring 13 is fixedly installed at the bottom end of each of the movable support rods 12. A rubber pad 19 is fixedly installed on the bottom surface of the circular suction ring 13. A limit ring 20 is fixedly installed on the outer surface of the movable support rod 12 on the top surface of the motor support plate 9. A suction hole 14 is opened on the inner wall of the circular suction ring 13. A flexible suction pipe 16 is fixedly installed on the outer surface of the suction hole 14. The end of the flexible suction pipe 16 away from the suction hole 14 is connected to an external suction mechanism. A return spring 15 is provided on the outer surface of the movable support rod 12. The bottom end of the return spring 15 is fixed to the top surface of the circular suction ring 13. The top of 5 is fixed to the bottom of the motor support plate 9. When the copper-clad laminate is being drilled, the mounting plate 7 and the motor support plate 9 press down to drive the circular suction ring 13 to move down synchronously. The rubber pad 19 adheres to the surface of the copper-clad laminate to form a sealed space. At the same time, it can also reduce the impact of the circular suction ring 13 on the copper-clad laminate. At this time, the suction hole 14 is connected to the external suction mechanism through the soft suction pipe 16, which can promptly suck up the debris generated by drilling. The reset spring 15 ensures that the circular suction ring 13 automatically resets when it moves up and down with the drill rod 11. The limit ring 20 restricts the movement range of the movable support rod 12 to prevent the suction ring from shifting, improve the suction efficiency and avoid debris accumulation. The external suction mechanism can consist of a dust collection box and a fan assembly.

[0027] refer to Figures 1-4 As shown, a connecting rod 17 is fixedly installed on the side of one of the two motor support plates 9, and a hose clamp 18 is fixedly installed at one end of the connecting rod 17. The hose clamp 18 can be used to fix the soft vacuum pipe 16, so as to prevent the pipe from getting tangled or shaking during the operation of the equipment, ensure the stability of the vacuum path, keep the equipment clean, and reduce pipe wear. The hose clamp 18 can be made of stainless steel.

[0028] The implementation principle of the copper-clad laminate drilling positioning device of this utility model is as follows: When in use, the operator first places the copper-clad laminate on the drilling table 3, aligning the edge of the board with the positioning mark on one side of the fixed seat 401. Then, the operator rotates the handwheel 403 to drive the two limiting clamps 404 to move synchronously through the bidirectional screw 402, which facilitates the positioning and clamping of the copper-clad laminate.

[0029] Subsequently, by adjusting the left-right and front-back adjustment mechanisms on the top of the support 2, the drilling platform 3 is moved in the X / Y axis direction. At the same time, the motor 803 of the adjustment mechanism 8 drives the lead screw 801, causing the threaded slide 802 to move the mounting plate 7 downward, thus facilitating the alignment of the drill rod 11 with the target drilling position. The second motor 10 is started, causing the drill rod 11 to press down and drill. At this time, the circular dust suction ring 13 moves down synchronously with the mounting plate 7 and the motor support plate 9, and the rubber pad 19 adheres to the surface of the board to form a seal. Then, the dust suction hole 14 sucks the debris into the external dust suction mechanism through the soft dust suction pipe 16. After drilling is completed, the drill rod 11 moves up, and the return spring 15 pushes the circular dust suction ring 13 to return to its original position. This device, through the clamping mechanism 4, can accurately position the copper-clad board. With the linkage adjustment of the adjustment mechanism 8 and the drill rod 11, the drilling position can be accurately controlled. At the same time, the circular dust suction ring 13 collects debris in real time, effectively solving the problems of low positioning efficiency and incomplete debris collection in traditional equipment.
