A screw thread automatic detection and sorting system for small mim products

Abstract

The invention discloses a screw thread automatic detection and sorting system for small-sized MIM products, which includes a casing and a feeding mechanism, a detection mechanism and a sorting mechanism arranged in the casing. The feeding mechanism includes a vibrating plate and a U-shaped manipulator. The mechanism includes a turntable and a fixture that can rotate counterclockwise. The turntable is provided with a discharging station, a testing station and a picking station in sequence along the counterclockwise direction. A CCD high-definition camera is installed at the testing station, and the lens of the CCD high-definition camera Facing the material placement position, the sorting mechanism includes a sorting frame, an assembly line module and a spider hand robot. The assembly line module includes a neatly arranged plate-putting module, a plate-setting module, and a closing module. One side of the sorting frame is provided with a throwing box. The invention has high degree of automation, high detection efficiency and accuracy, is applicable to the detection of large batches of components, and efficiently realizes the detection and sorting of small-sized MIM product screw threads, and has significant economic and social values.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a thread automatic detection and sorting system for small MIM products. Background technique [0002] MIM, or Metal Injection Molding, is a molding method that injects a plasticized mixture of metal powder and its binder into a model. It is suitable for mass production of small, precise, complex three-dimensional shapes and metal parts with special performance requirements. In the manufacture of components, in order to ensure that all the metal parts are qualified, these MIM products need to be tested after the manufacturing is completed, and the unqualified products are sorted out. For example, for small-sized MIM products with threads, in order to ensure that they can be used normally after being put into the market, it is necessary to inspect the threads of the threads. At present, most of the thread inspections of these small-sized MIM products are done manually. ...

For example, for small-sized MIM products with threads, in order to ensure that they can be used normally after being put into the market, it is necessary to inspect the threads of the threads. At present, most of the thread inspections of these small-sized MIM products are done manually. In the process of testing, inspectors rely on experience and special tools to complete the inspection work. However, due to the small size of small MIM products, this manual inspection method is greatly affected by human factors, and the detection accuracy is low. There will be misjudgments or missed judgments. Secondly, manual detection is time-consuming, labor-intensive, labor-intensive, and labor-intensive. For the detection of large-scale small MIM products at this stage, this detection method is obviously no longer possible. Meet the requirements of industrial development
