Embodiment Construction

[0018] refer to figure 1 , a kind of spraying equipment that the present invention proposes is provided with spray gun dredging structure, comprises: material box 1, confluence box 2, backflow pump 3 and nozzle 4, material box 1 connects nozzle 4 through hose, so that nozzle 4 extracts material box 1 The conductive adhesive inside is dispensed.

[0019] The confluence box 2 is provided with an input port 2-1 and a return port 2-2. The input port 2-1 is connected to the material box 1 through a pipeline, and the return port 2-2 is connected to the material box 1 through the return pump 3. The material box 1 and the confluence Tank 2 and return pump 3 constitute a circulation loop. In this way, after the backflow pump 3 works, the conductive glue in the material box 1 flows into the combiner box 2, and then returns to the material box 1 after the reflux pump 3, so as to realize the dynamic circulation of the conductive glue in the material box 1, so as to avoid the internal lea...

Abstract

The invention discloses spraying equipment with a spray gun dredging structure. The spraying equipment comprises a material box, a convergence box, a reflux pump and a spray head, wherein the materialbox is connected with the spray head through a hose; the material box, the convergence box and the reflux pump define a circulating loop; the front end of the spray head is of a tapered structure; apressure plate which is fixedly mounted on the inner wall of the spray head is arranged on the inner part of the spray head; the pressure plate is perpendicular to the center shaft of the spray head;the opposite two sides of the pressure plate inside the spray head communicate with each other; a tapered hole which is matched with the front end of the spray head is formed in the side wall of the convergence box; a telescopic pole which is parallel to the axial direction of the tapered hole is mounted on the inner wall of the convergence box; the free end of the telescopic pole is close to thetapered hole; the free end of the telescopic pole is equipped with a sealing plate; a spring sleeves the telescopic pole; and one side, away from a spring, of the sealing plate is equipped with a pushing rod in the extending direction of the spring. The spraying equipment is beneficial for preventing the spray head from being cleared frequently as a result of condensation of conductive adhesive inthe spray head, so that dispensing efficiency of the spray head is improved.

Description

technical field [0001] The invention relates to the technical field of conductive adhesive spraying, in particular to a spraying equipment provided with a spray gun dredging structure. Background technique [0002] Conductive adhesive is an adhesive with certain conductivity after curing or drying. It can connect a variety of conductive materials together to form an electrical path between the connected materials. In the electronic industry, conductive adhesive has become an essential new material. [0003] During the use of conductive adhesive, it is very easy to condense and precipitate, which causes the nozzle to be cleaned when it is suspended to prevent the conductive adhesive from condensing inside the nozzle and blocking the nozzle. As a result, during the glue spraying process, the nozzle needs to be cleaned frequently, which reduces the glue dispensing efficiency. Contents of the invention [0004] Based on the technical problems existing in the background tech...
