Automatic adhesive cleaning device and adhesive cleaning method thereof

Abstract

The invention provides an automatic adhesive cleaning device used for cleaning residual adhesives on a dispensing needle head. The automatic adhesive cleaning device comprises a fixed plate, material placing mechanisms, adhesive cleaning mechanisms, a guide mechanism and a material receiving mechanism, and the material placing mechanisms, the adhesive cleaning mechanisms, the guide mechanism and the material receiving mechanism are arranged on the fixed plate. Material belts are coiled into roll shapes and are loaded on the material placing mechanisms. The starting ends of the material belts are sequentially wound on the adhesive cleaning mechanisms and the guide mechanism and then are connected with the material receiving mechanism. In the process that the material receiving mechanism pulls the material belts, the material placing mechanisms, the guide mechanism and the material receiving mechanism act synchronously; the adhesive cleaning mechanisms clamp the dispensing needle head, so that the material belts are conveyed in the horizontal direction; the residual adhesives on the dispensing needle head are wiped on the material belts under matching of the material receiving mechanism and the adhesive cleaning mechanisms; and the material belts adhered with the residual adhesives are coiled on the material receiving mechanism under guiding of the guide mechanism. The automatic adhesive cleaning device and an adhesive cleaning method thereof are reasonable in design, high in efficiency, low in cost and high in automation degree.

Description

technical field [0001] The invention relates to the technical field of glue dispensers, in particular to an automatic glue clearing device and a glue clearing method thereof. Background technique [0002] Existing glue dispensing machines generally include a glue dispensing device with a needle and a controller. After the dispensing device has been processed for a period of time, there will be residual glue on the dispensing needle. If the residual glue accumulates a lot, it will affect the dispensing accuracy and further affect the product quality. Therefore, it is necessary to remove the residual glue on the dispensing needle. Especially the quick-drying glue dispensing machine uses quick-drying glue for dispensing, and the quick-drying glue will solidify quickly at room temperature, and it is easy to form residual glue on the inner surface of the needle or the tip of the needle due to the curing of the quick-drying glue, thereby causing needles Blockage of the mouth will...

AI Technical Summary

Problems solved by technology

Existing dispensing machines generally rely on manual wiping and cleaning to clean the needle residue. It is necessary to stop the machine and clean it directly or remove the dispensing needle to clean it, which affects the production speed, and the efficiency is low. Not clean enough

Especially when the shape of the needle is special, such as a curved needle, it is less efficient to manually remove the glue

[0003] And the existing manual cleaning of the needle residue of the dispensing machine is generally done by soaking the needle in a solvent such as dichloromethane, DMF and other solvents to clean it, and sometimes blowing the needle soaked in the above solvent with air, repeated 2 times. -3 times to clear

However, because the chemical preparations used are volatile and sometimes toxic, they are not environmentally friendly and healthy

In addition, special cleaning equipment, such as ultrasonic cleaning machines, can be added to clean the needle residue, but the cost will be relatively high, which increases the burden on the enterprise
