Description

Technical Field

[0001] The utility model relates to the technical field of PCB board drilling, in particular to a PCB board drilling device. Background Art

[0002] PCB, or printed circuit board, is an important electronic component. It is the support for electronic components and the carrier for electrical connections of electronic components. During production, PCB boards need to be punched according to assembly requirements, so drilling devices are needed to assist in the punching stage.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN218083036U discloses a protective device for drilling holes in PCB boards, including a table, two sets of parallel plates, an adjustable drilling component, a circulating cleaning component and a supporting processing component. The parallel plates are symmetrically mounted on both sides of the upper surface of the table. The utility model can cover and drill holes on the PCB board on the conveyor belt through the adjustable drilling component, and a circulating cleaning component is added to the drilling equipment. The circulating conveyor belt is used to keep the conveyor belt clean for subsequent processing, and avoid the situation where the waste residue on the conveyor belt causes the subsequent processed plate to lose stability and cause the drilling to break. The overall drilling work is protected and the burden on the staff is reduced. With the cooperation of the cleaning unit, the cleaning brush contacts the conveyor belt for cleaning. Starting the vibration motor can comprehensively clean the waste on the conveyor belt, keep the conveyor belt continuously clean, and enable the equipment to perform continuous drilling.

[0005] However, the above patent still has some problems that need to be improved during actual use. The most obvious one is that the relative position of the cleaning brush and the moving conveyor belt is fixed. When used for a long time, the cleaning brush will be worn due to friction with the conveyor belt, so that a gap will be generated between the cleaning brush and the conveyor belt, affecting the cleaning effect and efficiency of the waste on the surface of the conveyor belt.

[0006] To this end, we proposed a PCB board drilling equipment to solve the above-mentioned drawbacks. Utility Model Content
