Calibration system, calibration method and fluid spreading device

Abstract

The invention provides a calibration system, a calibration method and a fluid spreading device. The calibration method is used for calibrating the position of a glue dispensing head, the glue clearingposition and the weighing position of the calibration system and used for automatic calibration adopted after a glue dispensing head device of the calibration system is replaced. The calibration method comprises the steps that S1, through cooperation between a calibration camera and the coordinate position of the glue dispensing head, the horizontal position of the glue dispensing head is calibrated; S2, a laser height measuring sensor and a tool setting gauge cooperate to calibrate the vertical position of the glue spreading head; S3, through cooperation between the glue dispensing head or the calibration camera and a glue clearing device, the glue clearing position is calibrated; S4, the glue head or the calibration camera cooperates with the weighting device so as to calibrate the weighing position; S5, after the step S1, the step S2, the step S3 and the step S4 are completed, automatic calibration is achieved after replacement of the glue dispensing head device. According to the calibration method of the calibration system, the precision of the set glue dispensing height can be effectively improved, and good glue dispensing is achieved.

Description

technical field [0001] The present invention relates to the technical field of fluid spraying, more specifically, to a calibration system, a calibration method and a fluid coating device. Background technique [0002] Glue dispensing system is a kind of process equipment widely used in the field of product production. Its application scope covers product bonding, potting, coating, sealing, filling, scribing and gluing and other processes. The position accuracy of the dispensing system directly affects the effect of the dispensing process. Most of the existing technologies achieve the purpose of setting the dispensing height by directly specifying the dispensing height. This method has a large error and will directly affect the dispensing effect. [0003] The existing laser and camera position calibration method uses a target position in the calibration device, aligns the laser center and the camera center with the position respectively, and calculates the deviation value. ...

AI Technical Summary

Problems solved by technology

Most of the existing technologies manually calibrate the dispensing position on the calibration plate. This method has certain errors, and there is a risk of damaging the needle, which will directly affect the dispensing effect.

[0005] The existing calibration device is to set an automatic calibration positioning groove, a glue dispensing head height adjustment device, a glue cleaning device and a weighing device on a workbench fixed on the base. The automatic calibration device is a machined cross cursor or Positioning grooves, machining these on the entire table, make the machining parts complex, take up space, damage the parts or adversely affect the calibration efficiency and accuracy

The needle cleaning glue may not be clean enough by only using the glue cleaning function

Also the position calibration method for laser and camera position is slow
