A method of height compensation for dispensing position

Abstract

The invention discloses a height compensation method for an adhesive dispensing position. The height compensation method for the adhesive dispensing position comprises the steps that firstly, a height measurement detection position is set in a product to be subjected to adhesive dispensing, a positional relation between a visual system and an adhesive dispensing head is calibrated, and a height difference H between the visual system and the adhesive dispensing head is measured; secondly, a positional relation between a laser height measurement module and the visual system is calibrated, and a Z-coordinate Z1 of the visual system at the detection position, a Z-coordinate Z2 of the laser height measurement module at the detection position, and a height measurement value V1 from laser of the laser height measurement module to the detection position are measured; thirdly, the adhesive dispensing position of a second product to be subjected to adhesive dispensing is set; fourthly, a Z-coordinate Z3 of the laser height measurement module at the adhesive dispensing position and a height measurement value V2 of the laser, located at the adhesive dispensing position, of the laser height measurement module are measured; fifthly, a Z-coordinate novel Z of the adhesive dispensing position is represented by a formula: the novel Z = Z1+H-V1-Z2+V2+Z3; sixthly, the novel Z is compensated to the Z-coordinate of the adhesive dispensing position. The height compensation method for the adhesive dispensing position has the advantages that height compensation can be carried out on the adhesive dispensing position, so an adhesive dispensing effect is made to be stable.

Description

technical field [0001] The invention relates to a dispensing method, in particular to a method for height compensation of a dispensing position, Background technique [0002] Glue dispensing system is a kind of process equipment widely used in the field of product production, and its scope of use covers product bonding, potting, coating, sealing, filling, dripping, scribing glue and other processes. The position accuracy of the dispensing system directly affects the effect of the dispensing process, especially in contact dispensing. Most of the current technologies use the visual system to compensate the coordinates of the XY plane to achieve the purpose of position compensation. Due to contact dispensing, only compensating the XY coordinates can only achieve the effect of translation compensation, and the height of dispensing affects the final dispensing effect. When the height of the product to be dispensed is inconsistent, the dispensing method without height compensati...

AI Technical Summary

Problems solved by technology

Due to contact dispensing, only compensating the XY coordinates can only achieve the effect of translation compensation, while the height of dispensing affects the final dispensing effect

When the height of the product to be dispensed is inconsistent, the dispensing method without height compensation will not be able to achieve good dispensing

[0003] In summary, the dispensing method in the prior art has the following defects: the height of the dispensing, that is, the Z axis, cannot be compensated, and the dispensing effect is poor
