Description

Technical Field

[0001] The utility model relates to the technical field of dispensing equipment, in particular to a glue pushing device capable of accurately dispensing glue. Background Technique

[0002] A dispensing device, also known as a glue coating machine, a glue dropping machine or a caulking machine, is an industrial device. The main function of the dispensing device is to accurately dot glue, paint or other liquids on the surface or inside of a product, realizing various functions such as dotting, line drawing, circular or arc-shaped, etc., so as to improve production efficiency and product quality. This kind of equipment is widely used in fields such as semiconductors, chips, communication products, etc. For this reason, a glue pushing device capable of accurately dispensing glue is proposed.

[0003] For the existing Chinese utility model patent with the reference publication number: CN213102958U, it discloses a precise quantitative dispensing machine. In this kind of precise quantitative dispensing machine, a slidable sliding plug plate (5) is installed inside a dispensing machine housing (3), and a glue liquid (7) is filled inside the dispensing machine housing (3) at the bottom position of the sliding plug plate (5). After the structure is improved, a pushing shaft (13) is connected to the top of the sliding plug plate (5), and the other end of the pushing shaft (13) is connected to the output end of a stepping motor (9). The end face of the stepping motor (9) is threadedly fixed and installed on a shaft plate (11) through a threaded section (10). The beneficial effect is: for a precise quantitative dispensing machine, the original form of pushing and extruding the glue liquid (7) by air source is optimized into a mechanical extrusion form of the glue liquid (7), making the inaccuracy of the original discharge amount of the glue liquid (7) become the high-precision quantification of the mechanical extrusion of the glue liquid (7), and while ensuring the sealing performance of the movement and extrusion of the sliding plug plate (5), ensuring the accuracy of the extrusion amount, so as to improve the working precision of the dispensing machine.
