Chip turnover mechanism and thermistor chip welding equipment thereof

Abstract

The invention discloses a chip turnover mechanism and thermistor chip welding equipment thereof. The chip turnover mechanism comprises a turnover fixing base, a turnover driving device, a turnover guide device and a turnover conveying device; the turnover driving device, the turnover guide device and the turnover conveying device are arranged on the turnover fixing base; the turnover driving device is connected to the turnover guide device; and the turnover conveying device is arranged on the turnover guide device. The chip turnover mechanism has the advantages that through the turnover fixingbase, the turnover driving device, the turnover guide device and the turnover conveying device, the operation of overturning a chip can be realized, so that the chip can be subjected to the welding operation of the front and back sides, welding points on the welding surface cannot be touched, and therefore the welding efficiency and the welding quality of the chip can be improved.

Description

technical field [0001] The invention relates to the technical field of thermistor production and processing, in particular to a chip turning mechanism and thermistor chip welding equipment. Background technique [0002] Thermistors are a type of sensitive components, which can be divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors according to the temperature coefficient. A typical feature of a thermistor is that it is sensitive to temperature and exhibits different resistance values ​​at different temperatures. The higher the temperature of the positive temperature coefficient thermistor is, the greater the resistance value is, and the lower the resistance value of the negative temperature coefficient thermistor is when the temperature is higher, they are both semiconductor devices. [0003] During the production process of the thermistor, the chip of the thermistor needs to be welded. The traditional welding method is...

Problems solved by technology

[0003] During the production process of the thermistor, the chip of the thermistor needs to be welded. The traditional welding method is manual welding. The worker first welds the front of the thermistor chip through the welding torch, and then uses the welding torch to weld on the front of the thermistor chip. The reverse side of the thermistor chip is welded, and the manual flip operation of the chip is not only low in production efficiency, but at the same time, it is easy to touch the soldering point of the chip during the flipping process, which makes the soldering point on the chip easy to cause defects, thus Affect the quality of welding process
