Problems solved by technology

However, the above-mentioned light-curing glue bonder has the following disadvantages: the extrusion of the accommodating cavity is caused by the extrusion of the hose, which not only makes the operation inconvenient, but also makes it difficult to accurately measure the amount of glue extruded, resulting in poor controllability. Low, resulting in products prone to abnormal coating, resulting in rework or even scrapping of products, reducing the yield of finished products during production and processing

Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the drawings.

[0021] Such as figure 1 with figure 2 The light-curing glue bonder with an improved structure shown includes a main barrel 1 and a glue outlet 2 provided at the front end of the main barrel 1. Preferably, the main barrel 1 and the glue outlet 2 are integrated and fixedly connected. The main cylinder 1 is provided with a propelling piston 3, and an accommodating cavity 4 is formed between the main cylinder 1, the glue outlet 2 and the propelling piston 3. In order to prevent the leakage of glue, the front end of the propelling piston 3 is embedded and sealed with the main cylinder 1. Matching sealing ring 31. A glue nozzle post 21 is extended in the center of the glue outlet 2, and the glue nozzle post 21 is provided with a shaft hole 22 communicating with the accommodating cavity 4 along the axial direction. During operation, the shaft hole 22 serves as a channel for conveying light...

Abstract

The invention discloses a photocurable glue adhesion device adopting an improved structure. The photocurable glue adhesion device comprises a main barrel and a glue outlet formed in the front end of the main barrel, wherein a push piston is arranged in the main barrel, an accommodating cavity is formed among the main barrel, the glue outlet and the push piston, the main barrel is sleeved with a rotating barrel, and the rotating barrel is in transmission connection with the push piston; the rotating barrel drives the push piston to reciprocate in the axial direction of the main barrel when being rotated. The photocurable glue adhesion device is simple and reasonable in structure, convenient to operate and use and higher in controllability, the extruding amount of glue can be accurately measured, normal coating of products can be guaranteed, and the processing quality of the products can be improved.

Description

Technical field [0001] The invention relates to the technical field of light-curing glue bonding devices, in particular to a light-curing glue bonder with an improved structure. Background technique [0002] Light-curing glue is also called shadowless glue or photosensitive glue, which can quickly bond under the irradiation of ultraviolet light. With the development of the electronics manufacturing industry, the use of light-curing adhesives has become more and more widespread. Light-curing glue usually needs to be used with the help of a bonder. At present, the common light-curing glue bonders on the market are mostly in the form of syringe-shaped hoses. A deformable accommodating cavity is formed inside the hose. The accommodating cavity is used to accommodate light-curing glue. The head has a glue outlet that communicates with the accommodating cavity. When working, the accommodating cavity is deformed and compressed by squeezing the hose to promote the light-curing glue to ...
