Embodiment Construction

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. The foregoing and other objectives, features, aspects and advantages of the present invention will become more apparent, so that those skilled in the art can implement them with reference to the text of the description. In the drawings, the shape and size may be enlarged for clarity, and the same reference numerals will be used in all the drawings to indicate the same or similar parts. In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, and lower parts are based on the orientation or positional relationship shown in the drawings. In particular, "height" corresponds to the size from top to bottom, "width" corresponds to the size from left to right, and "depth" corresponds to the size from front to back. These relative terms are for convenience of description and are generally not intende...

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...
