Automatic tracking and dispensing method based on production line

Abstract

The invention discloses an automatic tracking and dispensing method based on a production line. The method comprises the following steps: firstly, a sensor or image acquisition is triggered to capturean image of an incoming material; secondly, the contour and position of the incoming material are shot by at least one image acquisition device; thirdly, a template and an image coordinate system areestablished based on images of the incoming material, a product is matched by a template matching method, an incoming material model is fitted in combination with morphological analysis, the image coordinate system is associated with an equipment motion coordinate system by a five-point calibration method, and coordinates and angles of the incoming material are determined; fourthly, an actual starting point corresponding to a machining track is determined based on the machining track and coordinates and angle of the incoming material; fifthly, a dispensing device is displaced to the actual starting point, and the position of the incoming material at any time after image capture and the running speed of the incoming material are judged by sensing; sixthly, the incoming material enters theactual starting point, and the dispensing device is controlled to move synchronously with the incoming material to perform dispensing; seventhly, the incoming material is glued, and a glue valve is cleaned to wait for the next incoming material.

Description

technical field [0001] The invention relates to technical fields such as intelligent manufacturing, equipment automation, and fluid control, and in particular to an automatic tracking dispensing method based on an assembly line. Background technique [0002] In the conventional product dispensing process, if most products are to be dispensed, the following processes are basically required: handling and loading—vehicle / mechanical positioning—visual positioning—gluing operation—handling and unloading, etc.; In this process, only the process of "gluing operation" really generates value, and the rest of the processes are auxiliary processes and are unnecessary. [0003] At present, there are roughly three dispensing methods in the industry, but they each have their own shortcomings. E.g: [0004] 1. Manual dispensing: rising labor costs, poor precision, completely dependent on the proficiency of the operator, and low yield rate; [0005] 2. Desktop glue dispensing machine: hi...

AI Technical Summary

Problems solved by technology

[0004] 1. Manual dispensing: rising labor costs, poor precision, completely dependent on the proficiency of the operator, and low yield rate;

[0005] 2. Desktop glue dispensing machine: high precision requirements for fixtures, unstable personnel;

[0006] 3. Fully automatic machine: high cost, requirements for the process before and after the assembly line, and poor flexibility

[0007] At the same time, in traditional dispensing operations, jigs / carriers are indispensable, which leads to the need to replace another product for production, you must stop, manually replace the carrier, debug the track, etc., to resume production, This step is time-consuming and laborious, and cannot meet the production scenarios of small batches, multiple batches, and multiple types of products on the production line
