Description

Technical Field

[0001] This utility model relates to the field of glue dispensing technology, and specifically to a two-component glue dispensing and vacuuming integrated machine. Background Technology

[0002] Dispensing machines are automated machines specifically designed to control fluid flow and dispense, coat, and encapsulate adhesive onto or inside product surfaces. They are widely used in modern large-scale industrial production. Currently, when some products undergo secondary assembly after the initial adhesive layer has been applied, air bubbles can easily form between the adhesive and the components being assembled. If degassing is not performed, numerous air bubbles will remain within the adhesive layer after surface dispensing, resulting in product defects.

[0003] In existing technologies, such as the PLC program and vacuum control device for two-component adhesive dispensing disclosed in Chinese patent document CN202210604225.2, although it can degas the product after the bottom layer adhesive is applied and after secondary assembly, and then apply the surface adhesive to remove air bubbles generated inside the adhesive during secondary assembly, and uses a precision screw metering pump to precisely control the adhesive supply and achieve accurate control of the A and B adhesive ratio, this device has the following problems: due to the long distance between the screw metering pump and the mixing tube, it is impossible to accurately control the amount of adhesive dispensed, and the mixing tube is prone to adhesive residue during dispensing, which directly affects the dispensing accuracy, causing problems such as stringing or adhesive breakage, and even reducing product yield. Utility Model Content
