Description

Technical Field

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

[0002] At present, a drilling machine is usually needed to drill holes in PCB boards during processing so that the circuit boards can achieve electrical connection. Existing PCB drilling machines do not have protective structures. During the drilling process, due to the thin board material, it is easy to cause the PCB board to break due to stress, which increases unnecessary economic losses.

[0003] For example, the utility model with patent number 201920445464.1 discloses a protective device for drilling holes in a PCB board, including a PCB board, wherein pressure plates are provided at the upper and lower ends of the PCB board, and a through hole is provided on the pressure plate. The protective device for drilling holes in a PCB board is provided with a pressure plate, and the pressure plate is used to cover both ends of the PCB board, so that the drill bit can directly drill holes in the PCB board through the "T"-shaped through holes of the pressure plate, thereby ensuring the accuracy of the drilling position of the PCB board and avoiding damage to the PCB board during the drilling process. The device is provided with a second fixing frame with a "Z"-shaped structure, and by pressing the tail end of the second fixing frame, the starting end of the fixing frame can be expanded along the fixed axis as the axis, thereby driving the pressure plate to separate from the PCB board. This operation method is fast and convenient, and provides an effective protective measure for the drilling process of the PCB board;

[0004] Although the protective device in this patent can circle and protect the drilling position of the PCB board, a large amount of waste chips will be generated during the drilling process and cannot be cleaned up in time. It is also necessary to use additional tools such as cleaning brushes to clean it, which makes it not very convenient to clean the surface of the PCB board. Utility Model Content
