Problems solved by technology

[0002] As the chip carrier of the inherited circuit, the lead frame acts as a bridge connecting the external wires. Most of the semiconductor integrated blocks need to use the lead frame. It is an important basic material in the electronic information industry. In order to improve production efficiency and improve material The utilization rate of semiconductors is convenient for batch processing of semiconductors. Therefore, a common lead frame is equipped with multiple chip nodes, and multiple chips are set on the chip nodes. After curing and packaging, the production of semiconductors is completed. After the production is completed , the semiconductor needs to be cut off from the lead frame, and the existing tailoring uses mechanical equipment for semiconductor tailoring, and the lead frames are placed in the tailoring device one by one continuously before cutting, although this method can realize However, since the lead frames need to be placed in the cutting device one by one by a special person, the work intensity of the operator is firstly increased, and the operator needs to place the lead frames continuously when the cutting device is running, which reduces the cutting of semiconductors. system efficiency

Abstract

The invention discloses lead frame plate placing and pushing-out equipment for semiconductor cutting. The lead frame plate placing and pushing-out equipment comprises a base, a top frame and a secondmotor. An arc-shaped hole is formed in the rear side of the base, a detection hole is formed in the rear side of the base, the detection hole is located in the right of the lower end of the arc-shapedhole, a sensor is fixed to the rear side of the base, the sensor and the detection hole are arranged in a front-back corresponding mode, and two transmission rollers are rotationally arranged in thebase and are in transmission connection through a belt. A first motor is fixed to the front side of the base, the output end of the first motor penetrates through the front side of the base to be fixed to the front end of one of the transmission rollers, and an electric push rod is fixed to the rear side of the base. According to the lead frame plate placing and pushing-out equipment for semiconductor cutting, the lead frame plates can be placed into the equipment without stop, then the lead frame plates are turned over to be placed and pushed into the cutting device, manual taking and placingare avoided, and the cutting efficiency is improved.
