Embodiment 1

[0030] Such as figure 1 and 2 As shown, a control method of a two-liquid dispensing automatic calibration system, the two-liquid dispensing automatic calibration system includes a glue supply device 1 and a two-component dispensing assembly 2, and the glue supply device 1 has a rubber cartridge A The A cylinder for pushing out the glue inside and the B cylinder for pushing out the glue in the B glue cartridge. The glue port is connected, and the glue inlet of the B rubber cylinder and the B screw pump 5 is connected. The control method includes the following steps:

[0031] Controller 3 can be initialized before step S1;

[0032] S1. Detect stroke difference. The difference between the current position of the push rod of cylinder A and the current position of the push rod of cylinder B is the stroke difference. If the stroke difference is greater than 5mm, the double-liquid dispensing automatic calibration system will stop and give an alarm; if the stroke difference ≤5mm, e...

Abstract

The invention relates to the technical field of double-component dispensing, in particular to a control method of a double-liquid dispensing automatic calibration system. The control method comprises the following steps: detecting a stroke difference; detecting whether a push rod of the cylinder A reaches a calibration flag position; after the push rod of the cylinder A reaches the calibration flag position, the relative position quantity of the push rod of the cylinder A and the relative position quantity of the push rod of the cylinder B are obtained; calculating the current output glue weight m; according to the position difference between the A cylinder push rod and the B cylinder push rod, the rotating speed of the A motor is adjusted; setting an adjustment coefficient K; adjusting the rotating speeds of the motor A and the motor B, the rotating speed final correction value of the motor A and the rotating speed final correction value of the motor B in equal proportion; the liquid level of a glue cylinder A and the liquid level of a glue cylinder B are monitored in real time, the consistency of the glue discharging proportion is guaranteed, the automatic calibration function is achieved, flow limitation is avoided, and the calibration requirement of high-precision micro glue dispensing can be met.

Description

technical field [0001] The invention relates to the technical field of two-component dispensing, in particular to a control method for an automatic calibration system for two-liquid dispensing. Background technique [0002] With the rapid development of the electronics industry, the requirements for electronic packaging technology are becoming more and more stringent. As one of the core technologies of electronic packaging, fluid dispensing technology is also facing the challenge of upgrading with high precision and high efficiency. In the dispensing process, due to the harsh storage conditions and easy deterioration of one-component glue, the market demand for two-component glue will increase, and the demand for two-component glue dispensing will also tend to Minimization and high precision. [0003] The two-component dispensing technology is generally completed by the two-component glue supply technology combined with the two-component glue ratio distribution technology, ...
