Problems solved by technology

In the prior art, when the chamber is evacuated, due to the large pressure difference between the air pressure in the chamber and the outside air pressure, and the time delay when the valve is closed, the vacuum value in the chamber will be unstable.
Moreover, the adsorption force generated by the large internal and external pressure difference has a high output power requirement for the valve closing mechanism, and the valve opening and closing mechanism with large kinetic energy will cause impact on the cavity and reduce its service life.

Abstract

The dispensing device comprises a vacuum bin body, a rack, a dispensing valve and a workbench, the vacuum bin body is installed on the rack, an extraction opening is formed in the outer surface of one side of the vacuum bin body, and a flange part extending inwards in the radial direction is arranged on the inner wall of the end, close to the interior of the vacuum bin body, of the extraction opening; a first flange plate is embedded into the extraction opening, a door opening is formed in the vacuum bin body, a sealing ring is arranged on the peripheral edge of the door opening, a movable door body is arranged on the front side of the door opening, the left side and the right side of the door body are each provided with a door frame, and linear guide rails are arranged on the portions, located on the left side and the right side of the door opening, of the vacuum bin body respectively. The two door frames are connected with the corresponding linear guide rails through sliding blocks respectively, so that the door body can move up and down in the vertical direction. Position deviation between the door body and the sealing ring caused by left-right shaking of the door body in the moving process can be avoided, and it is guaranteed that the sealing performance in the vacuum bin body is stable when the door body is in the closed state.

Description

technical field [0001] The invention relates to the technical field of vacuum cavity sealing, in particular to a glue dispensing device for precision parts. Background technique [0002] The vacuum chamber is mainly used in the field of product dispensing and packaging. Using the force of negative pressure, the air in the vacuum box is first pumped away during the pouring process, and then the product is poured, which can quickly penetrate the glue into the product and inject shock. And the bubbles generated by the contact between the glue and the product can also be quickly removed under the action of negative pressure, thus ensuring the high performance of the product. In the prior art, when the cavity is evacuated, due to the large pressure difference between the air pressure in the cavity and the outside air pressure, and the time delay when the valve is closed, the vacuum value in the cavity is unstable. In addition, the adsorption force generated by the large internal...
