Optical detection apparatus of parts

Abstract

The present invention discloses an optical detection apparatus capable of detecting and classifying parts with a certain shape and size. The optical detection apparatus comprises a frame, a rotation disc arranged on the frame, a material discharge device, an alignment device, an optical detection device and a classification unloading device, wherein the material discharge device, the alignment device, the optical detection device and the classification unloading device are arranged on the periphery of the rotation disc and are sequentially aligned, the rotation disc is connected with an annular detection platform provided for bearing and transmitting a part and manufactured from a transparent material, and the optical detection device comprises at least a set of level detection devices for detecting a front surface and / or a side surface of the part and at least a set of upright detection devices for detecting a bottom surface of the part. The optical detection apparatus has the following characteristics that: a structure is simple, and operation is convenient; with full-direction imaging detection of a part to be detected, the standard part can be detected, and the special-shaped part can be detected according to the size and the surface imaging of the part to be detected; and a detection result is accurate.

Description

technical field [0001] The invention belongs to the field of optical detection, in particular to an optical detection device capable of detecting and classifying parts with certain shapes and sizes. Background technique [0002] In assembly production, more and more automation equipment is used. If the parts to be assembled have defects, not only cannot realize normal automatic assembly, but also easily damage other parts and assembly equipment, reduce the pass rate of products, and waste product costs. , which brings troubles to the production of the enterprise, so most manufacturers require that the parts supplied must be 100% quality inspected, instead of the way of random inspection that was often used in the past. The existing inspection equipment has a complex structure, and the shape and material requirements of the equipment itself Information that is more stringent and not easy to judge the detected parts. [0003] The specification of Chinese patent CN202270656U d...

[0002] In assembly production, more and more automation equipment is used. If the parts to be assembled have defects, not only cannot realize normal automatic assembly, but also easily damage other parts and assembly equipment, reduce the pass rate of products, and waste product costs. , which brings troubles to the production of the enterprise, so most manufacturers require that the parts supplied must be 100% quality inspected, instead of the way of random inspection that was often used in the past. The existing inspection equipment has a complex structure, and the shape and material requirements of the equipment itself Strict and high and it is not easy to judge the information of the test piece

[0003] The specification of Chinese patent CN202270656U discloses a glass disk image screening device, which removes defective products from the parts to be tested through steps such as feeding, machine vision detection, and rejection, so as to realize the sorting of parts. The material is discharged from the material device and enters the circular glass plate. The circular glass plate rotates to drive the product into the correction device. Qualified products are blown and blanked by the blowing nozzle of the qualified product blanking device, and unqualified products are blown and blanked by the blowing nozzle of the unqualified product blanking device. The glass disk image screening equipment mainly uses a size detection device and diameter detection device to detect parts, the detection method is single, only standard parts such as hardware, fasteners and electronic components can be detected, and irregular shaped parts cannot be detected normally
