Abstract

The invention provides a dispensing device which is suitable for the field of dispensing. The dispensing device comprises a power system, a displacement amplifying system, a glue feeding system and an injection system, which are connected with one another through bolts, wherein a piezoelectric stack is used for powering the whole device; the displacement amplifying system is used for amplifying the displacement of the piezoelectric stack through an L-shaped hydraulic amplifying cavity, and a firing pin of the injection system impacts a nozzle under the displacement so as to jet a glue solution supplied by the glue feeding system. The dispensing device is dedicated to solving the problems that a current dispensing device cause large noise, and is not high in stability and low in frequency, the universality of the dispensing device is improved, and a good practical effect is achieved.

Description

technical field

[0001] The invention belongs to the field of glue dispensing, in particular to a non-contact glue dispensing device and system. Background technique

[0002] The dispensing system is a process equipment widely used in the field of product production. From semiconductor packaging industry, integrated circuit industry, SMT / PCB assembly industry to welding, injection coating and sealing in general industry, the process of sizing glue on points, lines and surfaces of colloids can be realized through this system. As the core component of the dispensing system, the dispensing device mainly solves the problem of automatic dispensing, which has an important impact on the dispensing speed, quality and shape of glue dots.

[0003] In the microelectronic packaging industry, in order to adapt to the irregularities of workpieces and pursue high-quality, high-speed, and high-precision dispensing devices, dispensing technology has gradually developed towards non-contact di...
