It should be noted that, due to the problem of debris and dust generated when the circuit board is polished, the present solution provides a dust collecting structure 10, wherein the clamping block 1004 is symmetrically fixed to the top of the inner wall of the mounting frame 1, and the fixed block 1003 is symmetrically fixed. Through the sliding structure of the fixed block 1003 and the clamping block 1004, the fixed block 1003 is correspondingly engaged and slides inside the clamping block 1004, so that the dust collecting basket 1002 can be limited to the top inside the mounting frame 1, and the fan 1001 is started, so that the debris at the top of the mounting frame 1 enters the dust collecting basket 1002 through the opening 7 for collection, thereby avoiding the accumulation of dust on the circuit board edge grinding device, which appears dirty.

Specifically, in this embodiment, the scheme mainly includes a dust collecting structure 10, and the dust collecting structure 10 includes a fan 1001. The fan 1001 is installed at the bottom end inside the mounting frame 1, and a clamping block 1004 is fixed to the top of the inner wall of the mounting frame 1, and a fixing block 1003 is arranged inside the clamping block 1004, and a dust collecting basket 1002 is fixed on the other side of the fixing block 1003. First, the fan 1001 is installed at the bottom end inside the mounting frame 1, and then the fixing blocks 1003 are symmetrically fixed on both sides of the dust collecting basket 1002, and then the clamping blocks 1004 are symmetrically fixed to the top of the inner wall of the mounting frame 1, and the fixing blocks 1003 are clamped in the internal sliding limit of the clamping blocks 1004, so that the dust collecting basket 1002 is limited to the top of the mounting frame 1, and the fan 1001 is started, so that the debris at the top of the mounting frame 1 can be collected in the dust collecting basket 1002, so as to avoid the accumulation of debris at the top of the device, which appears untidy and clean.
