[0041] There are two slide rails 24 , and the two slide rails 24 are symmetrically arranged.

[0042] The working principle is: When in use, the motor is started, and the motor drives the eccentric cam to rotate. The rotation of the eccentric cam then pushes the pulley to move, and then the pulley drives the sliding frame, the mounting seat and the vibrating screen frame to slide. The rotation of the eccentric cam drives the vibrating screen frame to continuously reciprocate back and forth, so as to achieve vibrating screen of the wafer on the fixed fixture, so that the wafer falls into the glass shell, thereby achieving the vibrating screen function of the device; When the eccentric cam drives the sliding frame to slide, the sliding frame drives the mounting seat, the driving shaft and the third gear to move. Since the rack is fixed, the third gear meshes with the rack while moving horizontally, so that the third gear and the driving shaft can rotate. The second gear on the driving shaft drives the first gear and the rotating shaft to rotate, so that the vibrating screen frame is tilted. With the reciprocating motion of the sliding frame, the vibrating screen frame is driven to shake left and right. After the vibration screening is completed, the staff can use the baffle to push the excess wafers into the collection box to collect the excess wafers on the fixed fixture.

When the fixed jig needs to be replaced, the staff can push the grip rod upward, and rely on the grip rod to move upward to push the push rod upward, so that the fixed jig can be lifted upward, thereby ejecting the fixed jig from the middle of the vibrating screen frame, so that the staff can take out the fixed jig conveniently, thereby facilitating the staff's use.

[0043] When the glass-sealed diode wafer vibrating screen device is used, the mounting seat is moved while driving the supporting seat to move, so that the third gear moves along the rack to drive the driving shaft to rotate, and the left and right tilting and swinging of the vibrating screen frame are realized under the cooperation of the first gear and the second gear, so that the vibrating screen frame can be tilted and swung left and right while shaking forward and backward, reducing the vibration amplitude and avoiding the situation of wafer aggregation, which is conducive to the dispersion of wafers in the vibrating screen frame, thereby improving the overall vibrating screen effect; In addition, the fixed fixture is installed on the fixed rod inside the vibrating screen frame, and through the cooperation of the push rod and the holding rod, the push rod can be driven to move upward by lifting the holding rod to push out the fixed fixture, so that personnel can disassemble the fixed fixture conveniently. In addition, a baffle is set inside the vibrating screen frame to limit the chip; and a collection box is rotatably installed on the side of the baffle opposite to the fixed fixture, which is convenient for collecting excess chips and dumping the chips in the collection box onto the fixed fixture, thereby improving the convenience of personnel operation.
