[0002] The motherboard is a core component of a computer device, responsible for crucial electrical connections and signal transmission. As electronic products evolve towards higher density and performance, the structure of motherboards is becoming increasingly complex, placing higher demands on their manufacturing precision and efficiency.

[0003] The motherboard drilling process generally includes board placement, positioning and clamping, drill bit alignment, drilling execution, and debris removal. Before drilling, the motherboard is placed on a base for positioning and fixation. The operator screws bolts around the base and places locating plates on the bolts to hold the edges of the board, achieving initial positioning and clamping of the motherboard. While this method achieves basic positioning, it is prone to damage to the edges of the board due to uneven torque of the locating plates or bolt misalignment during operation. Furthermore, the assembly and fixing steps are relatively cumbersome and time-consuming, affecting overall processing efficiency and the stability of mass production. Utility Model Content

[0004] The technical problem this invention aims to solve is that the assembly process during the laser processing and drilling of the motherboard is prone to damage and the operation is relatively cumbersome.

[0006] As a further improvement of this utility model, the two sides of the connecting block are respectively set as a first disk and a second disk, and the center is fixedly connected by a connecting column. A sliding groove for the connecting column to slide is provided on one side of the inner cavity, and the first disk is slidably connected to the inner cavity.

[0007] As a further improvement of this utility model, the second disc is provided with a mounting screw hole in the center, and the mounting screw hole is provided with a mounting bolt with internal threads, and the mounting bolt is fastened to both sides of the limiting clamp.

[0008] As a further improvement of this utility model, the clamping block has a clamping groove on one side and is made entirely of rubber material.

[0009] As a further improvement of this utility model, an assembly groove is provided on one side of the slot, and an assembly block that matches the assembly groove is fixedly connected to the inner side of the side plate.

[0010] As a further improvement of this utility model, an assembly bolt is provided on one side of the frame, and the assembly bolt passes through the slot and is fastened to the side plate. The side plate is provided with a plurality of assembly screw holes for the assembly bolt to be screwed into.

[0011] The beneficial effects of this utility model are as follows: The frame serves as an integrated processing platform, providing stable support. Side plates are securely fastened to both sides, with extension arms fixedly connected to the inner sides of the side plates. These extension arms, via internal springs, automatically return to their original position and adjust with the connecting blocks. Simultaneously, a clamping block on one side of the limiting clamping plate holds and limits the mainboard substrate, facilitating laser drilling of the mainboard in subsequent processes. The first and second discs on both sides of the connecting blocks, adjusted via connecting columns, enhance the linkage stability between the limiting clamping plate and the extension arms. Furthermore, the clamping mechanism is firmly fixed with assembly bolts, ensuring reliable structural connection during drilling. In addition, the clamping blocks are made of rubber and feature a groove design, preventing edge damage to the substrate caused by traditional bolt-based limiting, providing flexible contact and anti-slip support, improving the yield rate of mainboard processing, and making it suitable for batch, high-precision drilling production scenarios.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides a fixed-point drilling device for computer motherboards, including a frame 1;

[0021] As attached Figure 1-4 As shown, the frame 1 has a central mounting platform for motherboard processing. Grooves are formed on both sides of the frame 1, and side plates 2 are installed within these grooves. Extension arms 3, extending inwards, are fixed to both ends of the side plates 2. The extension arms 3 are L-shaped rods with an inner cavity at one end, extending through the end of the extension arm 3. A spring is fixed to the inner wall of the inner cavity, and a connecting block 4 that slides within the inner cavity is fixed to the other end of the spring. A limiting clamping plate 5 is fastened between the two connecting blocks 4. A clamping block 6 for gripping the edge of the motherboard is fixedly connected to the inner side of the limiting clamping plate 5. The clamping block 6 has a clamping groove on one side and is made entirely of rubber; this provides anti-slip properties while ensuring reliable clamping of both sides of the motherboard. A handle is fixed to the outer side of the limiting clamping plate 5 for easy adjustment. Simultaneously, this equipment, combined with the drilling head of the Haiyi HY-FB01 laser cutting device, performs drilling operations on the motherboard on the mounting platform.

[0022] As attached Figure 2 , 3 As shown, the connecting block 4 has a first disc 401 and a second disc 402 on both sides, which are fixedly connected by a connecting column. A sliding groove for the connecting column is provided on one side of the inner cavity, and the first disc 401 is slidably connected to the inner cavity; the first disc 401 ensures slidable connection with the extension arm 3. The second disc 402 has an assembly screw hole in its center, and an assembly bolt 7 is threaded inside the assembly screw hole. The assembly bolt 7 is fastened to both sides of the limiting clamp 5; the second disc 402 is used to reinforce the connection of the limiting clamp 5 to be assembled later.

[0023] As attached Figure 4 As shown, to minimize the space occupied by the frame 1 during transportation, a detachable mechanism is used between the frame 1 and the side plate 2. An assembly slot is provided on one side of the slotted section, and an assembly block 8 matching the assembly slot is fixedly connected to the inner side of the side plate 2. When the side plate 2 is connected to the frame 1, assembly is performed through the assembly block 8 and the assembly slot. An assembly bolt 9 is provided on one side of the frame 1, and the assembly bolt 9 passes through the slot and is securely connected to the side plate 2. The side plate 2 has multiple assembly screw holes for the assembly bolt 9 to screw into; the assembly bolt 9 and the assembly screw holes ensure a secure structural connection.

[0024] Working Principle: In practical application, this invention first connects the side plate 2 to the mounting slot at the side opening of the frame 1 via the assembly block 8. The assembly bolts 9 are then screwed into the pre-set assembly screw holes to secure the structure, thus completing the foundation erection. Next, the operator pulls the limiting clamp 5 outwards, compressing the spring in the inner cavity of the extension arm 3. This causes the first disc 401 in the inner cavity to move inwards, placing the main plate on the mounting platform of the frame 1, ensuring that its edge engages with the clamping block 6 of the limiting clamp 5 on the other side. The limiting clamp 5 is then slowly released, moving it inwards towards the frame 1. The spring in the inner cavity of the extension arm 3 returns to its original state, causing the clamping block 6 to hold the edge of the main plate, achieving stable positioning. The rubber clamping blocks 6 on both sides ensure even force distribution on the main plate when clamped, preventing damage to the edges and corners, and providing good anti-slip properties. Finally, a laser drilling machine is used to drill holes in the mounting plate main plate.
