High-precision adjustable chip diode suction pen structure

The invention provides a high-precision adjustable chip diode suction pen structure which comprises a suction pen body, a conical suction nozzle is formed in the bottom of the suction pen body, and a vacuum air cavity is coaxially formed in the suction pen body. The position, close to the suction nozzle, of the suction pen body is sleeved with a limiting sleeve, and the lower portion of the limiting sleeve is connected with an anti-deviation block through a bolt. An anti-deviation receding cavity is formed in the center of the bottom of the anti-deviation block. The bottom of the suction nozzle penetrates through the anti-deviation block, and the vacuum air cavity is communicated with the anti-deviation receding cavity. Auxiliary clamping structures are arranged on the two opposite sides, located on the deviation preventing receding cavity, of the deviation preventing block. The auxiliary clamping structure comprises fan-shaped blocks arranged on the two opposite sides of the deviation prevention receding cavity correspondingly and buffer springs connected with the fan-shaped blocks. The two opposite side walls of the deviation prevention receding cavity are each provided with a displacement receding groove for containing the corresponding fan-shaped block and the corresponding buffer spring. The clamping device has the beneficial effects that the size of the clamping space can be automatically adjusted by being matched with a product, and the situation of clamping or crushing damage is effectively avoided.
