A processing device for electronic components

Abstract

The present invention discloses a processing device for electronic components. The present invention sets a transmission mechanism. When the handle is pushed counterclockwise, the linkage rod pushes the long column and the gear to move to the right. The gear rotates while moving to the right, and pulls the pushing mechanism to the right through the transmission chain. When the pushing mechanism moves to the right, since the upper end of the shift rod is inserted between two adjacent tooth blocks, the shift rod pushes the movable plate to the right, so that the movable plate can migrate the processed circuit boards from under the engraving machine and continue to process the next batch of circuit boards, thereby greatly improving the processing efficiency. When the handle is pushed clockwise, the linkage rod pulls the long column to move to the left. At this time, under the action of the connecting spring, the pushing mechanism automatically moves to the left and resets. When the pushing mechanism resets, under the joint action of the reset spring, the shift rod tilts and flips to the right, and will not drag the movable plate.

While the swivel seat 84 is rotating, the connecting rod 85 gradually changes from a vertical state to an inclined state, so that the lifting platform 88 moves downward. When the lifting platform 88 moves downward, it can drive the push-pull rod 513 and the piston 512 to move downward, so that the internal air pressure of the hollow rod 511 is reduced, and suction is generated on the upper part. The suction is transmitted to the circuit board to be processed through the through hole 21. The circuit board to be processed is fixed on the movable plate 2 by adsorption. At this time, the circuit board can be processed. After the processing of the circuit board is completed, the handle 81 is rotated counterclockwise, and the connecting rod 85 gradually changes from an inclined state to a vertical state, so that the lifting platform 88 moves up, thereby driving the push-pull rod 513 and the piston 512 to move up, so that the air pressure inside the hollow rod 511 increases, generating a blowing force upward, and the blowing force is transmitted to the circuit board to be processed through the through hole 21, so that the circuit board is released. When the handle 81 is swung, the connecting rod 85 can be moved upward by the linkage rod The long column 745 of 742 moves inside the short column 746. When the handle 81 is pushed counterclockwise, the linkage rod 742 pushes the long column 745 to move to the right. Since one end of the transmission chain 72 is fixedly connected to the right-angle rod 73, the gear 747 rotates while moving to the right, and the pushing mechanism 71 is pulled to the right through the transmission chain 72. At this time, the connecting spring 748 is gradually stretched. When the pushing mechanism 71 moves to the right, the upper end of the shifting rod 711 is inserted between the two adjacent tooth blocks 23. Therefore, the shifting rod 711 It will push the movable plate 2 to move to the right, so that the movable plate 2 can move the processed circuit boards to the right from under the engraving machine 4 and continue to process the next batch of circuit boards. When the handle 81 is pushed clockwise, the linkage rod 742 will pull the long column 745 to move to the left. At this time, under the action of the connecting spring 748, the pushing mechanism 71 will automatically move to the left and reset. When the pushing mechanism 71 is reset, the lever 711 will tilt and flip to the right under the joint action of its own conical head and the reset spring 712, and will not drag the movable plate 2.
