Problems solved by technology

[0003] The glue in the prior art is often mixed with air to generate air bubbles. When the glue mixed with air bubbles is used in a dispensing machine, it will not only make the glue flow poor and affect the dispensing effect, but also cause the valve to close. drip risk
The current glue degassing device has the disadvantages of low degassing efficiency and incomplete degassing

Embodiment 1

[0017] Such as figure 1 As shown, in the electronic processing glue centrifugal defoaming device of the present embodiment, a centrifugal cylinder is arranged above the base 1, and the centrifugal cylinder includes an outer cylinder 201 and an inner cylinder 202, and the top of the outer cylinder is provided with a glue adding port. A cover plate 9 is provided at the liquid addition port, a glue discharge port 10 is provided at the bottom of the outer cylinder, and a valve 11 is provided at the glue discharge port. The side walls of the blocks are spliced ​​by hinged arc-shaped plates in turn. The arc-shaped plates are connected to the side wall of the outer cylinder through the spring 4. The outer cylinder is connected to the base through the rotating shaft 5. The rotating shaft is driven to rotate by the motor 3. Specifically, The rotating shaft is provided with a driven pulley 7 that rotates synchronously with the rotating shaft, and the output shaft of the motor is provide...

Embodiment 2

[0019] Compared with Embodiment 1, this embodiment is different in that: a circulation pipe 12 connecting the bottom and top of the outer cylinder is provided on the side wall of the outer cylinder, a circulation pump 13 is provided on the circulation pipe, and the outer cylinder is close to The position of the top is straddled with a glue spray pipe 14 communicated with the circulation pipe, and the side wall of the glue spray pipe is evenly provided with a plurality of glue spray holes, and glue spray nozzles 15 are arranged in the glue spray holes. . The circulation pump works, and the glue is pumped from the bottom of the centrifugal cylinder to the top, and sprayed out through the glue spray nozzle, thereby improving the fluidity and dispersion of the glue, and further improving the efficiency and effect of defoaming.

Embodiment 3

[0021] Compared with Embodiment 1 and Embodiment 2, the difference of this embodiment is that a vertical shaft 18 is arranged in the center of the glue spraying pipe, and a spiral stirring blade 19 extending axially along the vertical shaft is arranged on the vertical shaft. During the centrifugal defoaming process of the glue, due to the viscosity of the glue, the rotation of the glue will be slower than that of the centrifugal cylinder, and the vertical shaft and the centrifugal cylinder will rotate synchronously, so the spiral stirring blade will have a stirring effect on the glue, thereby increasing the viscosity of the glue. Centrifugal action is beneficial to the defoaming of glue.

Abstract

The invention discloses a glue centrifugal de-foaming device for electronic processing. The device comprises a base, a centrifugal barrel and a motor; the centrifugal barrel comprises an outer barrelbody and an inner barrel body; the inner barrel body is formed by assembly of multiple arc-shaped plates with side walls connected sequentially in a hinged manner; the arc-shaped plates are connectedwith the side wall of the outer barrel body through springs; a rotating shaft rotationally connected with the base is arranged at the bottom of the outer barrel body; and the rotating shaft is drivento rotate by the motor through a transmission structure. With the device adopting the structure, the glue de-foaming efficiency and effect are effectively improved.

Description

technical field [0001] The invention relates to the field of glue degassing, in particular to a centrifugal degassing device for glue used in electronic processing. Background technique [0002] In the production process of various electronic devices or circuit boards, a glue dispenser is often used. The glue dispenser is also called a glue applicator, a glue dispenser or a glue pouring machine, etc., to control the fluid. An automatic machine that drips and coats the fluid on the surface of the product or inside the product, which can realize three-dimensional and four-dimensional path dispensing, with the advantages of precise positioning, precise glue pulling and no wire drawing. Its working principle is: the glue is stored in the glue storage room formed by the rubber cylinder and the piston, the glue storage room is connected with the dispensing nozzle through the feeding pipe, and a valve is set at the connection between the dispensing nozzle and the feeding pipe, thro...
