Feedback adjustment spraying dispensing device and adjusting method thereof

Abstract

The invention relates to the technical field of dispensing, in particular to a feedback adjustment spraying dispensing device and an adjusting method thereof. A valve body is included and comprises avalve body upper shell and a valve body lower shell. The valve body lower shell is provided with a collision pin hole, and a collision pin is arranged in the collision pin hole in a sliding manner. The valve body lower shell is further provided with a glue inlet pipeline communicating with the collision pin hole. The outer portion of the lower shell is in threaded connection with a limiting threaded sleeve. A nozzle communicating with the collision pin hole is arranged at the bottom end of the limiting threaded sleeve. Glue spraying is achieved through collisions of the collision pin and the nozzle. A cavity is formed in the valve body upper shell, a lever is arranged in the valve body upper shell, a piezoelectric stack is fixed to the top end of the cavity, the collision pin upwards extends into the cavity, the piezoelectric stack abuts against the lever, the outer portion of the collision pin is sleeved with an elastic element, one end of the elastic element abuts against the lever,and the other end of the elastic element presses the valve body upper shell. The cavity is internally provided with a displacement sensor probe for detecting the lever moving distance. According to the feedback adjustment spraying dispensing device and the adjusting method thereof, the nozzle adjusting efficiency is high, and reliability is high.

Description

technical field [0001] The invention relates to the field of dispensing technology, in particular to a feedback-adjusted jet dispensing device and an adjustment method thereof. Background technique [0002] With the rapid development of the electronic industry in today's society, the surface mount technology in the electronic packaging industry has also been rapidly improved. In the surface mount technology, the dispensing technology for electronic products has also been developed rapidly as its core. Among them, the non-contact jet dispensing technology does not need to move in the height direction, so the dispensing speed and dispensing accuracy have been greatly improved. At the same time, because the piezoelectric stack-driven non-contact jet dispensing device has a high speed And the advantages of high precision, so it is favored by people in the non-contact jet dispensing mechanism. [0003] The non-contact jet dispensing mechanism realizes non-contact dispensing thro...

Problems solved by technology

[0006] In order to solve the defects in the prior art that the gap between the nozzle and the striker cannot be sprayed normally due to the gap between the nozzle and the striker being too large or too small, the present invention provides a feedback adjustment device that is convenient for adjusting the gap between the nozzle and the striker and reducing the error caused by the distance problem.
