Gas-assisted glue-hanging-prevention atomization device with adjustable glue width

Abstract

The invention discloses a gas-assisted glue-hanging-prevention atomization device with adjustable glue width. The gas-assisted glue-hanging-prevention atomization device is provided with an adjustingassembly, a gas inlet cap, a glue outlet assembly, an atomization cap and a flow stabilizing plug; the flow stabilizing plug is placed in the atomization cap; the adjusting assembly is fixed to the outer wall of the atomization cap; a flow stabilizing gas passage is arranged on the inner wall of the flow stabilizing plug; the adjusting assembly is provided with adjusting lead screws and a fixing piece; the outer wall of the atomization cap is sleeved with the fixing piece, and the adjusting screw rods are installed in adjusting screw holes in the two ends of the fixing piece; the gas inlet capis in threaded connection with the atomization cap; and the glue outlet assembly is provided with a glue outlet nozzle and a glue outlet pipe, the glue outlet nozzle is fixed to the top end of the glue outlet pipe, and the other end of the glue outlet pipe penetrates through the interior of the gas inlet cap and the flow stabilizing plug and extends into the atomization cap. The problem of glue hanging is solved, related components are adopted, so that the edge resolution of glue is greatly improved, and the glue is prevented from entering the gas passage to influence glue discharging; and the glue width is changed by controlling the related components to cope with a complex dispensing environment.

Description

Technical field[0001]The patent of the invention relates to the field of glue dispensing, in particular to a glue dispensing process with high viscosity and precise film width requirements, and more specifically to an anti-sticking glue gas-assisted atomization device that can control the height and thus the spray film width.Background technique[0002]Dispensing equipment is currently a process equipment widely used in mechanical production and processing, and its scope of use covers product bonding, potting, coating, sealing, filling, dripping, scribing and gluing processes. It can achieve the functions of waterproof, light leakage, heat conduction, electrical conductivity, adhesion, dustproof, encapsulation, reinforcement and so on. The dispensing method is divided into: contact dispensing and non-contact dispensing. Contact dispensing uses a certain pressure to push the glue through needles with different inner diameters to achieve the purpose of dispensing. Non-contact dispensing...

AI Technical Summary

Problems solved by technology

There are the following problems: 1) The nozzle will hang glue at the end. At the beginning of the next cycle of spraying, the glue hanging on the glue head will be sprayed to the target position first, resulting in a "big head" (such as figure 1 As shown), it affects the stability of the glue; 2) The width of the glue is not adjustable, and often needs to be dispensed multiple times; 3) Before this, the bottom of the atomizing airway is a plane, and the gas will generate a swirl after hitting the wall. Blow the glue back into the bypass airway, block the airway, and further deteriorate the atomization effect
