Problems solved by technology

[0006] (3) When the dispensing equipment is mass-produced, there are certain errors in the fixtures, motion systems and vision systems of different equipment, which also leads to the manual calibration of the product workpiece dispensing or glue application trajectory of each dispensing equipment. And during manual calibration, all glue dispensing or glue application tracks in the XY dimension of the product workpiece plane need to go through a series of cumbersome operations such as continuously moving the needle for calibration, resulting in a long debugging time;
[0007] (4) The error of manual calibration greatly affects the accuracy of the dispensing effect, which in turn affects the sealing performance of the product workpiece after dispensing

Abstract

The invention discloses a dispensing method, system and device based on visual guidance and a storage medium. The method comprises the following steps: calibrating a camera, and determining the relation between an image coordinate system and a world coordinate system; calculating the distance between the camera and the dispensing needle head; point gluing track information is obtained from a provided CAD standard glue road drawing file and registered as a standard template; collecting image information of the product workpiece by using a camera, and comparing the image information with the standard template to determine a deviation value; according to the deviation value, point gluing track information after deviation of the product workpiece is calculated; According to the deviated point gluing track information, the distance between the camera and the dispensing needle head and the mechanical coordinate when the camera collects the image, the actual point gluing track information of the product workpiece is calculated, and the dispensing operation is assisted. According to the invention, the time and the workload of personnel for adjusting the dispensing track can be obviously reduced, the dispensing precision is high, the dispensing track is stable, and the production quality and the production efficiency are greatly improved.

Description

technical field [0001] The invention relates to the field of glue dispensing technology, in particular to a vision-guided glue dispensing method, system, equipment and storage medium. Background technique [0002] Glue dispensing is a process, also known as sizing, gluing, glue pouring, glue dropping, etc., which is to drip, smear, and seal electronic glue, oil or other liquids on the surface or inside of the product workpiece, so that the product workpiece can be lifted. To paste, potting, insulation, fixation, smooth surface and so on. The application range of dispensing is very wide, ranging from large airplanes and ships to small productions such as clothes, toys, and electronic components, all of which may require dispensing. [0003] At present, in the existing automatic dispensing system, the vision system deviation method is more commonly used to guide, which requires the dispensing system handheld box or dispensing software to preset the dispensing track of the pro...
