Device and method for automatically supplying glue water

Abstract

The invention discloses a device and a method for automatically supplying glue water. The device comprises a pressure storage barrel, a control switch, a dispensing tube and a liquid level sensor. The pressure storage barrel is connected with the dispensing tube through a duct; when the liquid level sensor monitors lower limit information of the liquid level, the liquid level sensor transmits the lower limit information of the liquid level to the control switch, the control switch controls turn-on of the duct, and the pressure storage barrel conveys the glue water to the dispensing tube in a pressing way; when the liquid level sensor monitors upper limit information of the liquid level, the liquid level sensor feeds the upper limit information of the liquid level back to the control switch, and the control switch controls turn-off of the duct. According to the device and the method for automatically supplying glue water provided in the invention, the glue water is not needed to be manually replaced, and a condition that a rubber tube is linked with a large glue water tube again and air bubbles infiltrates in a conventional glue supply mode is avoided. The waste of the glue water is avoided, and the product yield is improved. Meanwhile, according to the method for automatically supplying the glue water, the time of replacing the glue water is saved, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of glue dispensers, more specifically, to a device and method for automatically supplying glue. Background technique [0002] Some existing electronic products need to use a glue dispenser during processing. For example, in the process of making a touch display screen, it is necessary to bond the touch screen and the display screen, and a glue dispenser is required for lamination. At present, the glue supply methods for the water-glue bonding process of touch screens and displays include: the glue dispenser directly uses large sticks of glue, that is, the large sticks of glue are introduced into the dispensing valve through the rubber tube, and then glued. However, when replacing the large glue, it is necessary to connect the joint of the rubber tube with the large glue. During the connection process, the steam drum will inevitably seep into the glue. Therefore, after replacing the large glue, the dispensing...

Problems solved by technology

However, when replacing the large glue, it is necessary to connect the joint of the rubber tube with the large glue. During the connection process, the steam drum will inevitably seep into the glue. Therefore, after replacing the large glue, the dispensing valve must be opened for glue removal. to remove air bubbles

The existing glue supply method not only requires manual replacement of glue, but also causes a lot of waste of glue
