Description

   Adjusting method for cutting dust-suction brush of plate cutter   

The method for adjusting the dust suction brush of the cutting cutter of the plate splitter of the present invention is mainly applied to the dust suction technology during circuit board cutting. The axial displacement device is used to allow the brush holder to cooperate with the milling cutter of the processing spindle when adjusting the milling position. , Automatically make the axial high and low displacement, to avoid the brush down too tight or floating too loose to interfere with the accuracy of the milling cutter milling and affect the effect of vacuuming.

According to the general circuit board, the so-called board edge cutting and sub-board movement must be performed. In order to avoid the dust, copper foil, tin balls and other debris generated by the sub-board machine from cutting the circuit board, it will fall on the circuit board. Therefore, the dust, copper foil, tin balls and other debris must be sucked away with a vacuuming device, and the vacuuming device generally uses a brush to surround the vicinity of the milling cutter to form a vacuuming area.

However, because the thickness of the circuit board is only 3 ~ 4mm, and the length of the milling cutter of the processing spindle is 10 ~ 15mm, when the milling cutter of the processing spindle is cutting and milling a certain number of circuit boards (about 100 or 200) After that, the milling cutter will become hot and hot, so the industry will lower the milling cutter height or increase it by a few mm to avoid excessive wear of the milling cutter, and also ensure the precision of the milling cutter in cutting and milling circuit boards. When the height of the milling cutter is lowered or raised, the brush must be axially displaced along with the milling cutter; otherwise, when the position of the brush is pressed too low, it will be deformed. When the milling cutter is cut and milled, A side force will be generated, which will affect the accuracy of cutting the circuit board. When the position of the brush is too high, a gap will be formed in the vacuuming area, which will affect the vacuuming effect.
