Automatic sorting equipment and method for injection molded parts

Abstract

The invention provides automatic sorting equipment and method for injection molding parts. The method comprises the steps of collecting binocular images of the injection molding parts; according to apreset grabbing position, grabbing point coordinates in the binocular image are recognized, and the spatial position of the grabbing point coordinates in the three-dimensional space is obtained through mapping; grabbing the injection molding part according to the spatial position, and moving the injection molding part to a defect detection position; collecting an appearance image of the injectionmolding part at the defect detection position; and according to the appearance image, performing defect recognition on the injection molding parts, and placing the injection molding parts in a classified mode according to the recognition result. According to the technical scheme provided by the embodiment, the defects of the injection molding parts can be automatically recognized, the injection molding parts can be automatically sorted according to the defect types, the sorting efficiency of the injection molding parts can be improved, the manual sorting cost is reduced, and the sorting accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an automatic sorting device and a sorting method for injection molded parts. Background technique [0002] my country has the largest injection molded parts processing industry in the world, with a huge volume of product shipments and a wide variety of products. With the improvement of automation level, the processing and manufacturing of injection molded parts has basically realized assembly line production. The steps of batching, baking, feeding, injection molding, cooling, post-processing and other steps of injection molded parts can be produced automatically without human intervention. However, the quality inspection, sorting, coding, packaging and other links of injection molded parts generally rely on manual operations. [0003] Existing automated sorting equipment can save labor to a certain extent, and the solution can be briefly described as follows:...

AI Technical Summary

Problems solved by technology

[0005] The disadvantages of the above existing solutions are: 1. The automatic sorting equipment cannot realize online quality inspection, and the quality inspection depends on manual

The efficiency of manual detection is low, and the reliability of detection is difficult to guarantee

If a full inspection is carried out, more inspection personnel are required, which greatly increases the personnel cost of the inspection process

2. The setting of automatic sorting equipment is relatively cumbersome. In the manufacture of injection molded parts, it is often faced with the situation that there are many types of parts, many batches, and each output is small.

The use of automation equipment will reduce production efficiency
