[0027] Furthermore, such as Figure 1 and Figure 2 As shown, a storage box 2 is fixedly connected to the top of the base plate 1; the storage box 2 is a box-shaped structure with a notch at one end; multiple L-shaped baffles 21 are fixedly connected to the inner wall of the storage box 2; the multiple L-shaped baffles 21 are symmetrically arranged; during operation, a storage box 2 is set on the top of the base plate 1, and multiple L-shaped baffles 21 are fixedly connected to the inner wall of the storage box 2.

The bolt 34 is rotated so that the suction cup 35 at the end of the bolt 34 is attracted to the multi-layer circuit board, thus fixing the multi-layer circuit board. By fixing the multi-layer circuit board in multiple directions, the multi-layer circuit board can be kept stable when being drilled, preventing the circuit board from being damaged due to excessive pressure.
[0029] Furthermore, such as Figure 1 and Figure 4 As shown, multiple replacement boxes 4 are installed on the top of the base plate 1; the multiple replacement boxes 4 are located on both sides of the storage box 2 and are symmetrically arranged; the replacement boxes 4 can hold the base 31; during operation, multiple replacement boxes 4 are installed on the top of the base plate 1, and the multiple replacement boxes 4 are located on both sides of the storage box 2. At the same time, the replacement boxes 4 are hollowed out in the middle to hold the base 31. When placing multi-layer circuit boards, the base 31 needs to be taken out from the slot 3 first, and then the base 31 is placed inside the replacement box 4.

When drilling holes in multilayer circuit boards, debris may appear, affecting the drilling accuracy. Therefore, when drilling, the power of the air duct 52 is turned on, so that the air duct 52 blows air towards the drilling area to blow away the debris.
[0031] Furthermore, such as Figure 3As shown, the inner wall of the storage box 2 is provided with multiple cleaning ports 6; the multiple cleaning ports 6 are symmetrically arranged; during operation, multiple cleaning ports 6 are provided on the inner wall of the storage box 2, and the multiple cleaning ports 6 allow debris to pass through. By providing cleaning ports 6 on the inner wall of the storage box 2, the debris remaining on the surface of the storage box 2 can be reduced, thus protecting the drilling work of the multilayer circuit board.
[0032] Working principle: During operation, support frames 11 are installed on both sides of the top of the base plate 1. A first linear drive 12 is fixedly connected to the top side wall of the support frame 11. A second linear drive 13 is fixedly connected to the side wall slider of the first linear drive 12. A connecting block 14 is fixedly connected to the side wall slider of the second linear drive 13. A third linear drive 15 is fixedly connected to the side wall of the connecting block 14. A fixing block 16 is fixedly connected to the side wall slider of the third linear drive 15. An electric drill 17 is fixedly connected through the fixing block 16. A condenser box 18 is installed on the side wall of the electric drill 17. By using the first linear drive 12, the second linear drive 13, and the third linear drive 15 in different positions, the electric drill 17 can move in all directions. When drilling multilayer circuit boards, overheating can occur, potentially damaging or even melting the boards. Therefore, a condenser box 18 installed on the side wall of the drill 17 cools it down. By adding coolant or water to the hollowed-out center of the condenser box 18, it can be kept close to the drill 17 during operation, effectively cooling its side wall and reducing the impact of the drill 17's heat on the multilayer circuit board. A storage box 2 is installed on the top of the base plate 1, with multiple L-shaped baffles 21 fixedly connected to its inner wall. These baffles 21 are symmetrically arranged. A notch is left at one end of the storage box 2, allowing the multilayer circuit board to be easily placed on it. The L-shaped baffles 21 are designed to... The multilayer circuit board is fixed and adjusted so that it can be easily and neatly placed on the storage box 2 for the next step of drilling. Multiple slots 3 are made on the top inner wall of the storage box 2. Multiple bases 31 are connected to the side walls of the slots 3. A connecting rod 32 is fixedly connected to the top of the base 31, and a collar rod 33 is fixedly connected to the side wall of the connecting rod 32. A bolt 34 is threaded to the end of the collar rod 33, and a suction cup 35 is fixedly connected to the bottom of the bolt 34. Before placing the multilayer circuit board, the bases 31 connected to the side walls of the slots 3 are removed. Then, the multilayer circuit board is placed on the storage box 2, and the bases 31 are placed inside the slots 3. The bolts 34 are rotated so that the suction cups 35 at the ends of the bolts 34 adhere to the multilayer circuit board, thus securing the multilayer circuit board. The circuit board is fixed in multiple directions to maintain its stability during drilling, preventing damage due to excessive pressure. Multiple replacement boxes 4 are installed on the top of the base plate 1, located on both sides of the storage box 2. Each replacement box 4 has a hollow center to accommodate a base 31. When placing the multi-layer circuit board, the base 31 must first be removed from the slot 3 and then placed inside the replacement box 4. This method prevents the base 31 from being lost and provides a temporary storage location. Multiple fixing seats 5 are fixedly connected to the top of the base plate 1. Support rods 51 are connected to the top of the fixing seats 5, and air ducts 52 are connected to the side walls of the support rods 51.When drilling multilayer circuit boards, debris and other contaminants can affect drilling accuracy. Therefore, during drilling, the power to the air duct 52 is turned on, allowing air to blow away the debris. Multiple cleaning ports 6 are provided on the inner wall of the storage box 2 to allow debris to pass through. By providing cleaning ports 6 on the inner wall of the storage box 2, the amount of debris remaining on the surface of the storage box 2 can be reduced, thus protecting the drilling process of the multilayer circuit boards.
