A dispensing compensation method based on glue flow detection

Abstract

The invention discloses a glue dispensing compensation method based on glue flow detection, comprising a glue dispensing compensation system, the glue dispensing compensation system including a glue receiving mechanism, a fixing seat, an optical fiber sensor, an amplifier, a PC industrial computer, a driver and glue dispensing Execute the motor and dispensing compensation steps are as follows, S1, install and connect the components involved in the dispensing compensation system correctly; S2, set the dispensing compensation program and parameters on the PC industrial computer; S21, perform dispensing compensation by adjusting the rotating shaft; S22. Dispensing compensation by adjusting the air pressure; the present invention automatically calculates the proportional value of the dripping speed change through different dripping speeds, and automatically adjusts the speed or air pressure of the dispensing control system in equal proportions to achieve the effect of stably compensating glue, and the compensation technology is stable , improve debugging efficiency and accuracy, and have good market application value.

Description

Technical field [0001] The present invention relates to the field of dispensing compensation technology, in particular to a dispensing compensation method based on glue flow detection. Background [0002] With the development of industry and technology, the industry on the dispensing process requirements are getting higher and higher, mainly manifested in the dispensing line width more and more extreme, glue volume control is getting smaller and smaller and more stable, resulting in equipment demand dispensing glue weight control more and more precise, at the same time, the popularity of industrial automation, a series of module optimization of the equipment to be designed around the core of automatic no one intervention, and due to the dispensing needle inner wall of the glue curing and the viscosity of the glue change, resulting in the dispensing needle out of the glue will also change, Therefore, it will often take human intervention to adjust the dispensing control system, at...

Problems solved by technology

[0002] With the development of industry and technology, various industries have higher and higher requirements for dispensing technology. The main performance is that the line width of dispensing is getting more and more extreme, and the control of glue volume is getting smaller and more stable, which leads to the dispensing glue required by the equipment. Heavy control is becoming more and more precise. At the same time, with the popularization of industrial automation, a series of module optimization of equipment must be designed around the core of fully automatic unmanned intervention, and due to the curing of the glue on the inner wall of the dispensing needle and the viscosity of the glue Changes will lead to changes in the glue output of the dispensing needle, so human intervention is often required to adjust the dispensing control system. At present, in the dispensing industry, the way to monitor the glue volume is mainly through the weighing module. Weigh the weight of the glue dispensed per unit time, and then adjust the dispensing speed, but because of the needle dispensing process, the weighing method is not ideal, because the glue is easy to stick to the needle, resulting in the amount of glue not being accurately weighed. , and an error occurs
