First level lead screw is connected between end, and the second horizontal lead screw, the first level are connected between riser and the rear end of the first guide rail
Lead screw and the second horizontal lead screw with the second guide rail screw-thread fit, and pass through between first level lead screw and the second horizontal lead screw
Chain wheel driving mechanism connects.The above structure can drive the second horizontal lead screw to synchronize fortune when rotating first level lead screw
Turn, the second guide rail is made to move in the horizontal direction, to realize the adjusting of distance between the first guide rail and the second guide rail, to adapt to not
With the needs of width dimensions circuit board transport, it is easy to operate, convenient to adjust.
In order to keep operation more effortless, in one end of the first level lead screw, installation is shaken the hand.
It is equipped with guide rod parallel with it in the left and right sides of the vertical lead screw, the upper end of the guide rod and supporting block
Bottom is mutually fixed, and the lower end of guide rod passes through positioning plate.Guide rod plays a part of to be oriented to, and makes supporting block and sieve rack only vertical
Direction moves, to ensure the reliability of screening.
Preferably, multiple screening blocks are set from top to bottom in the sieve material strip, two adjacent screenings in same sieve material strip
The distance between block is equal.
In order to simplify structure, making easy to process, the screening block is packet, and is structure as a whole with sieve material strip.
Advantageous effect：The configuration of the present invention is simple, compact, good reliability, high degree of automation, when there is defective work,
Whole circuit board production line need not be shut down, and defective work is screened out on screening machine to be placed aside, and whole line can be after
Continuous production, thus greatly accelerates production efficiency, and complete product classification well.
