Bicolor keycap glue feeding device and glue feeding method thereof

Abstract

The invention relates to the field of production of bicolor keycaps, in particular to a bicolor keycap glue feeding device and a glue feeding method of the bicolor keycap glue feeding device. The bicolor keycap glue feeding device comprises glue feeding bodies (1) and spray nozzles (2) connected with the glue feeding bodies (1). Each spray nozzle (2) is in an arc bent shape as a whole. The sharp point (3) of each spray nozzle (2) is bent to the inner side edge of the edge of a corresponding keycap (4). When the bicolor keycap glue feeding device and the glue feeding method of the bicolor keycap glue feeding device are used for feeding glue, even if glue point burrs are formed after glue feeding is ended, the glue point burrs are on the inner side of the edge of the keycap and are not exposed, the attractiveness of the keycaps 4 and the whole keyboard cannot be influenced, it is not needed to remove the burrs through manpower and physical materials, and the product cost is reduced to a certain extent.

Description

technical field [0001] The invention relates to the production field of a two-color keycap, in particular to a two-color keycap glue feeding device and a glue feeding method thereof. Background technique [0002] The two-color keycap is molded by glue injection during production. In the existing molding device, the glue injection nozzle is generally a straight-through nozzle, and the glue in the nozzle receives a higher pressure and a faster speed. This leads to a little protruding glue dot burr on the outer edge of the keycap when the glue injection is completed, and the glue dot on the keycap is generally at the outer edge of the keycap. If it is left on the keycap, It will seriously affect the aesthetics of the keyboard, so after the dipping process, it is often necessary to manually grind off the burrs of the glue dots to ensure the aesthetics of the keycaps. Contents of the invention [0003] The purpose of the present invention is to provide a two-color keycap glue ...
