Description

Technical Field

[0001] The invention relates to the technical field of thermistor production, and in particular to an automatic feeding device for thermistors. Background Art

[0002] A thermistor is a sensor resistor whose resistance value changes with temperature. It is divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors according to different temperature coefficients. The resistance value of a positive temperature coefficient thermistor increases with increasing temperature, while the resistance value of a negative temperature coefficient thermistor decreases with increasing temperature. They are both semiconductor devices, and when producing thermistors, it is often necessary to solder wires to the pins of the thermistor to facilitate the subsequent use of the thermistor.

[0003] When welding existing thermistors, a vibration plate is usually used to vibrate multiple thermistors, and then the thermistors are transported to the slide rail with the pins facing downward. The telescopic rod is then used to drive the clamping cylinder to clamp the thermistor and feed it to the welding station. The welding station then clamps the pins of the thermistor to weld the wires, and the clamping cylinder then returns and clamps again, resulting in poor feeding continuity of the thermistor and low feeding efficiency. At the same time, some thermistor pins collide after production or in the vibration plate, causing the position of the pins to shift. After feeding, the shifted pins cannot be corrected, resulting in the pins after feeding being unable to be aligned when welding the wires, resulting in welding failure. Summary of the invention

[0020] Beneficial effects of the present invention:

[0021] (1) The drive mechanism drives the mounting shaft and the transmission plate to rotate intermittently, and then the thermistor is clamped by the clamping mechanism on the transmission plate. Then, the thermistor pin is adjusted and the clamping mechanism is used to slowly correct the pins of the thermistor, so that some deviated pins are corrected, and then the welding station is entered to realize continuous automatic loading of thermistor welding, and then the wires on the pins are welded. When the welding is completed, the thermistor pin adjustment clamping mechanism clamps and fixes the welding position to prevent the welding position from falling off during subsequent movement, thereby realizing continuous automatic loading of the thermistor.

[0023] (3) By driving the adjustment box to move, the adjustment box is moved between the pins of the thermistor, and then the adjustment airbag on the adjustment box is inflated. The entire airbag applies force to both sides of the pin, and the pin is pushed slowly and flexibly to correct some pins that are out of position, which is convenient for subsequent welding of the thermistor wires. At the same time, the adjustment airbag is used to perform a flexible and slow correction, which effectively prevents excessive force from being suddenly applied during the correction process, causing the pin and the thermistor body to loosen, resulting in damage to the thermistor, thereby improving the correction effect of the thermistor.
