Embodiment approach

[0035] Such as Figure 1-2As shown, between the slider 216 and the second pole 212, the slider 216 after the adjusted position is limited and fixed by the second adjustment assembly. As an embodiment of the present invention, the second adjustment assembly includes The second adjusting screw 221 and the second nut 222 threadedly connected with the second adjusting screw 221, one end of the second adjusting screw 221 is provided with a stop portion 223 with a diameter greater than the diameter of the second adjusting screw 221, on the slider 216 is provided with a second screw hole 224, the second adjusting screw 221 extends from the upper end of the second pole 212 through the second screw hole 224 from the lower end of the second pole 212, and passes through the second nut 222 Threaded connection, the limiting portion 223 abuts against the lower end of the second pole 212 , thereby preventing the fixed slider 216 from coming out of the third guide hole 215 .

Abstract

The invention provides an automatic dust removal device. The automatic dust removal device comprises a top blowing-sweeping assembly, a bottom blowing-sweeping assembly, a gas generation device and an electric control box. The invention further provides a plate dividing machine. The plate dividing machine comprises a dust collecting mechanism and a conveying mechanism, and further comprises the automatic dust removal device. The top blowing-sweeping assembly is arranged above the conveying mechanism located at an outlet of the plate dividing machine. The bottom blowing-sweeping assembly is arranged on the dust collecting mechanism. A controller is connected with a controller body of the plate dividing machine. Compared with the prior art, the bottom blowing-sweeping assembly and the top blowing-sweeping assembly are arranged, residual dust on the surface of a PCBA circuit board is precisely removed through the gas generation device, and accordingly, the problem that the function of the PCBA circuit board is abnormal due to the residual dust on the surface of the PCBA circuit board is solved; and the bottom blowing-sweeping assembly and the top blowing-sweeping assembly are controlled through the electric control box, so that automation is achieved.

Description

technical field [0001] The invention relates to a PCB board technology, in particular to an automatic dust removal device and a board separating machine. Background technique [0002] The basic process of printed circuit board SMT process in typical mobile phone products is as follows: SMT printing process-SMT patch process-SMT reflow process-PCBA segmentation; in the manufacture of mobile phone products, in order to improve production efficiency, PCBs are generally designed as multi-panel , such as 3-piece, 4-piece or 6-piece, after completing SMT printing, placement, and reflow, use a fully automatic board splitter to divide the multi-piece board into single-piece boards for testing and assembly. In the existing fully automatic board splitting machine, in order to collect the dust generated when PCBA is split, a dust collection cylinder (with built-in dust collection bag and exhaust filter) is used. Its working principle is: the circuit board is separated by a vacuum pump ...
