[0003] Circuit board drilling is an important process in the PCB production process. Drilling can provide electrical connection paths between different layers of the circuit board, ensuring that current can be smoothly transmitted between the layers.

[0004] For example, the patent with publication number CN213971574U specifically discloses a crack-proof circuit board drilling device, which includes an operating table, a base, a clamping mechanism, a circuit board, a longitudinal sliding mechanism, a transverse sliding mechanism, and an adjustment mechanism. Thus, when drilling holes on the circuit board, the circuit board is fixed to prevent the circuit board from being offset and causing damage to the circuit board.

[0005] When the above-mentioned circuit board drilling device is in use, the circuit board is clamped between the clamping plates by the first compression spring. However, when drilling the circuit board, the spring will expand or deform due to the force of the drill bit, resulting in the circuit board being not stable and accurate enough, thus affecting the drilling accuracy, and further causing the hole position deviation. Therefore, it is necessary to design a multi-layer circuit board drilling device to solve the above-mentioned problem.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0008] The technical solution adopted by the present application to solve its technical problem is: a multi-layer circuit board drilling device. It mainly includes: an operating table; a drilling component, which is installed on the operating table and is used to drill holes in a multi-layer circuit board; a fixing component, which is installed on the operating table and includes: two groups of second slide rails, which are installed on the operating table, and two groups of second sliders are installed on the second slide rails; an L-shaped plate, which is installed between the two groups of second sliders, and a second clamping plate is installed on the L-shaped plate; a fixing seat, which is installed on the L-shaped plate, and the fixing seat has a protruding end; a screw, which is connected to the protruding end, and a first clamping plate is installed on the screw.

[0009] Furthermore, a fixing pin is inserted on the second sliding block.

[0010] Furthermore, a handle is installed on the screw rod.

[0011] Furthermore, a baffle is installed on the second clamping plate.

[0012] Furthermore, anti-skid pads are installed on one side of the second clamping plate and the first clamping plate close to the circuit board, and the anti-skid pads are made of elastic material.

[0013] The beneficial effect of the present application is that the multi-layer circuit board drilling device provided by the present application can firmly clamp the multi-layer circuit board through the arrangement of the second slide rail, the second slider, the fixing pin, the L-shaped plate, the fixing seat, the protruding end, the screw, the first clamping plate, the second clamping plate and the baffle plate, so as to avoid the hole position deviation caused by position offset during drilling.
