Clamping conveyer belt for semiconductor marking machine

Abstract

The invention discloses a clamping conveyer belt for a semiconductor marking machine. The clamping conveyer belt structurally comprises a conveyer belt body, a clamping fixture and a pressing frame. According to the clamping conveyer belt, after infrared sensors in the middle of a framework detect that a semiconductor chip board passes through, an external pneumatic pipeline supplies air to an airinlet of a second cylinder body, so that an internal rod extends to the front end, a second clamping block moves forwards to locate the left side of the rear end of the moving semiconductor chip board, then the external pneumatic pipeline supplies air to an air vent of the cylinder body, and a piston cylinder in the cylinder body is pushed to the front end to drive a clamping block at the front end of a fixed block to move so as to fixedly clamp the front side of the right end of the semiconductor chip board; and after marking is completed, a controller controls the external pneumatic pipeline to be ventilated, so that an exhaust port of a second cylinder body is ventilated, an internal rod of the second cylinder body contracts backwards, the clamping fixture clamps and locates the semiconductor chip board, the equipment marking precision is further improved, the deviation of the marking position is avoided, and the production yield is increased.

Description

technical field [0001] The invention relates to the field related to semiconductor processing, in particular to a clamping conveyor belt for a semiconductor marking machine. Background technique [0002] Laser marking machine uses laser beams to mark permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to engrave the label. Before marking the semiconductor chip, it is often carried out by conveyor belt. The transmission is placed on the bottom end of the marking machine, and then sent to the left end of the production line to be transported out. The production line uses manual assembly, which requires multiple personnel, high labor costs, and direct accumulation. The height difference between the ordinary conveyor belt and the plane is high, and the drop on the plane will affect The quality of the semiconductor chip board causes the chip position to deviate due to jitt...

[0002] Laser marking machine uses laser beams to mark permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to engrave the label. Before marking the semiconductor chip, it is often carried out by conveyor belt. The transmission is placed on the bottom end of the marking machine, and then sent to the left end of the production line to be transported out. The production line uses manual assembly, which requires multiple personnel, high labor costs, and direct accumulation. The height difference between the ordinary conveyor belt and the plane is high, and the drop on the plane will affect The quality of the semiconductor chip board causes the chip position to deviate due to jitter or belt-to-belt transmission during the ordinary conveyor belt transmission process. For some precision and small ICs that are directly marked during the transportation process, the marking position will deviate and affect the marking. Code display effect, but manual assembly takes a long time, and the ordinary conveyor belt falls directly from a high place, which will cause damage to the semiconductor chip
