Currently, most of them are clamped by a PCB board forming machine, and the processing tools are used to drill holes on the PCB embryo to obtain a PCB board that meets the shape requirements. However, due to the small overall size of the PCB embryo, the corresponding processing tools are also relatively slender. Therefore, when the processing tools are processed at high speed, the processing tools are prone to swing or shake greatly under the action of centrifugal force, which may cause the processing tools to break, thereby affecting the subsequent processing of the PCB embryo.

[0008] In summary, the present application has the following beneficial effects:
[0009] By fitting the inner side surface of the limiting hole with the outer side surface of the processing tool, the space for the swing or shaking of the processing tool when the processing tool rotates inside the through hole is limited, so that the processing tool will not swing or shake greatly when rotating, which effectively solves the technical problem that due to the small overall size of the PCB embryo, the corresponding processing tool is also relatively slender. Therefore, when the processing tool performs high-speed processing, the processing tool is prone to swing or shake greatly under the action of centrifugal force, thereby causing the processing tool to break, thereby affecting the subsequent processing work of the PCB embryo.

In this embodiment, when the processing tool is working at high speed, The outer side surface of the processing tool will fit with the inner side surface of the limiting hole 13 for rotation. The inner side surface of the limiting hole 13 fits with the outer side surface of the processing tool, so that the swing or shaking space of the processing tool when the processing tool rotates inside the through hole 2 is limited, so that the processing tool will not swing or shake greatly when rotating, which effectively solves the problem that due to the small overall size of the PCB embryo, the corresponding processing tool is also relatively slender, so when the processing tool performs high-speed processing, the processing tool is prone to swing or shake greatly under the action of centrifugal force, thereby causing the processing tool to break, thereby affecting the subsequent processing of the PCB embryo. In addition, by adjusting the distance that the driving member 4 drives the slider 5 to move horizontally inside the slide groove 3, the processing tools of different diameters can be limited and protected, effectively improving the practicality of this product.
[0019] The dust collecting head body 1 is provided with sockets 7 on both sides, and the sockets 7 are transversely penetrated through the dust collecting head body 1 and connected with the through hole 2, and sensing optical fibers 8 are inserted in the sockets 7. In the present embodiment, when the processing tool enters the dust collecting head body 1 through the through hole 2, the sensing optical fiber 8 will sense whether there is an object penetrating the dust collecting head body 1. The sensing optical fiber 8 senses the telescopic state of the processing tool in the through hole 2 to judge whether the processing tool is intact. The processing tool can be monitored to avoid empty drilling during the processing of the PCB embryo (not shown in the figure) due to the breakage of the processing tool.
[0020] A double-ear connecting platform 9 is provided on one side of the dust collecting head body 1, and the double-ear connecting platform 9 is connected to the main shaft of the PCB board forming machine (not shown in the figure), and the dust collecting head body 1 is fixed on the main shaft of the PCB board forming machine through the double-ear connecting platform 9.

In this embodiment, since the PCB board forming machine will generate a large amount of dust during operation, the first closing opening 11 is designed for this purpose.
