Multi-camera multi-thread detection system

Abstract

The invention discloses a multi-camera multi-thread detection system and a detection method thereof. The system comprises a rack, a PLC, and an industrial personal computer, wherein the rack is provided with a vibration disc which enables the directions of to-be-detected workpieces to be unified; a discharging runner of the vibrating disc extends to a feeding mechanism; the system further involvesa transparent rotating disc, the transparent rotating disc is driven by a stepping motor to rotate; a feeding area, a photographing area and a falling area are sequentially arranged along the periphery of the transparent rotating disc; a plurality of stations are uniformly arranged on the transparent rotating disc, and a product is placed on each station; two photographing positions are sequentially arranged in the photographing area on the side of the transparent rotating disc; and three falling boxes, namely an OK falling box, an NG falling box and a tailing box, are sequentially arranged in the falling area. The system has the advantages that 1) the plasticity is high, specifically, the system can be transformed to test similar products, a hardware part does not need to be replaced basically, the cost is further saved; and 2) the operation is simple, specifically, a parameter setting window is developed, debugging is convenient, and production personnel can complete the operation.

Description

technical field [0001] The invention discloses a detection system, in particular to a detection system with multiple cameras and multiple threads. Background technique [0002] In the metal powder metallurgy process, the production of MIM components requires large processes such as injection molding and sintering. In this process, the quality of the product depends most on the quality of the corresponding grinding tools, sintering and other processes. Nowadays, it is difficult to achieve inspection-free products, so product inspection is an indispensable link. At present, there are mainly the following detection methods: [0003] The use of machine vision is also growing rapidly in this industry. [0004] 1) Traditional detection methods, such as calipers, diaphragms, etc., have low efficiency and cannot meet production needs. [0005] 2) The method of automatic visual inspection is adopted. This method can automatically load the material, use the PLC to control the came...

Problems solved by technology

[0006] During the research and practice of this product size, I found that the efficiency of manual operation is low. When automatic testing is used, when one camera tests one part, there is still a large test space, which is easy to cause waste of space. In order to meet the Due to the demand for production, it is necessary to increase the number of machines and equipment several times. Therefore, a test method with multiple threads of a camera is invented, which can meet the production needs while reducing the number of machines.
