Inner wall vision detection device for annular object

Abstract

The invention discloses an inner wall vision detection device for an annular object, which comprises a base, wherein the left end of the base is provided with a lifting mechanism, an image pickup assembly is fixed on a lifting slider of the lifting mechanism, a workpiece rotating table is arranged on the right side of the image pickup assembly, the workpiece rotating table is hinged on a moving seat capable of moving left and right through bearings, the front end and the rear end of the moving seat are inserted into a sliding rail arranged in the left-right direction, a connecting rod protruding leftwards is fixed on the moving seat, a piston rod of an air cylinder is arranged in parallel with the slide rail, an outer ring gear is formed on the outer wall of the workpiece rotary table, a driving gear is connected with a speed reduction mechanism fixed on the base, and a driving motor is arranged in the speed reduction mechanism. The inner wall vision detection device is simple in structure and can realize automatic detection, a detected workpiece can automatically rotate, so that the annular workpiece is convenient to measure, an LED stable light source is arranged on a camera, sothat high-definition images can be obtained, the identification rate of the workpiece damage is greatly increased, the operation is simple, and the cost is greatly reduced.

Description

Technical field [0001] The invention relates to the field of detection technology, in particular to a visual detection device for the inner wall of a ring body. Background technique [0002] In the prior art, after the various components of the circuit board are welded and packaged, it is necessary to perform some defect detection on the circuit board to ensure that the output circuit board is a finished product, and then the circuit board installation or subsequent follow-up can be completed for the later stations. The factory sales and other work of the circuit boards are guaranteed, so the inspection of the circuit boards is very important. Machine vision inspection can easily cope with the quality control of metal parts production, such as coins, auto parts, connectors, etc. Through image processing methods, defects such as scratches, defects, discoloration, and mucous membranes on the surface of metal parts are found. At present, visual inspection is the detection of some d...

Problems solved by technology

[0003] At present, the existing technology has the following problems: one, most of the visual inspection mechanisms are not suitable for the internal detection of some special workpieces; to get a clear image, so that accurate judgments cannot be made; the third is that the ring-shaped workpiece is a circle, and there are certain difficulties in image acquisition.
