A new type of steel ball unfolding and sorting device for visual inspection

Abstract

The invention relates to a novel steel ball spreading and sorting device for visual inspection. The novel steel ball spreading and sorting device comprises a feeding mechanism, a feeding channel, a detection slot, a feeding disc, a fan-shaped supporting block, an eccentric wheel, a slide block, a sorting disc and a discharging channel, wherein the feeding mechanism is connected with the feeding disc which is arranged in the detection slot through the feeding channel; the fan-shaped supporting block, the slide block and the sorting disc are arranged below the feeding disc in parallel; the adjacent end faces of the fan-shaped supporting block, the slide block and the sorting disc are in tight fit with one another; the upper surfaces of the fan-shaped supporting block, the slide block and the sorting disc are flush with one another; the eccentric wheel is connected with a feeding rotating shaft; the eccentric wheel drives the slide block to do reciprocating motion towards a radial direction of the feeding rotating shaft. The novel steel ball spreading and sorting device is simple in structure, low in equipment control difficulty and low in manufacturing and operating cost and overcomes the defect that a ball outlet channel of a traditional gate control ball outlet mechanism is long in state switching time.

Description

technical field [0001] The invention relates to an automatic detection device, specifically, a device that realizes the full expansion of the steel ball surface under machine vision through the coordinated movement of a mechanical mechanism, and controls the ball-out mechanism to realize steel ball sorting according to the detection feedback information. device. Background technique [0002] The product surface defect detection method based on machine vision has been more and more widely used in the field of automatic detection due to its characteristics of non-contact, rapidity and accuracy, and achieved good results. [0003] Chinese invention patents with patent numbers ZL200310109912.4 and ZL200810243613.2 respectively disclose a detection method and device for steel ball surface defects. The steel ball feeding and unfolding mechanisms disclosed in these two patents require three motors to drive. The Chinese invention patent with the patent number ZL201210168658.4 discl...

AI Technical Summary

Problems solved by technology

The overall structure of these motion mechanisms is relatively complex, which will increase the difficulty of equipment control and the cost of manufacturing and operation.

[0004] In terms of steel ball sorting, the traditional gated ball discharge mechanism has a long public channel for the genuine product and the defective product, so there is a switching time between the state of the ball discharge channel (that is, the state of the genuine product and the state of the defective product) long disadvantage
