Embodiment

[0024] Such as figure 2As shown, a cylindrical product appearance detection system of the present invention is used to detect the surface appearance of cylindrical electronic components, including a frame 9, two rollers 10 are arranged on the frame 9, and the transmission belt 6 is tightened between the two rollers. 10, one of the rollers 10 is driven by a drive mechanism, driven by the drive mechanism, the conveyor belt 6 can rotate between the two rollers 10, the two flat panels 7 are fixed on the frame 9, and the two flat panels 7 and the conveyor belt 6 The gap between them is 1 mm, and a detection channel 8 is formed between the two flat plates 7. An angle α is formed between the detection channel 8 and the moving direction of the conveyor belt 6. When the cylindrical product 2 advances a unit length in the axial direction, The circumferential direction rotates exactly 360°, so the ideal α angle should be arctan(L / 2πR), where arctan is the arc tangent function, R is th...

Abstract

The invention discloses an appearance detection system for a cylinder product. The appearance detection system comprises a line scanning camera and further comprises a conveyor belt, wherein two flat plates are fixed above the conveyor belt; a detection channel is formed between the two flat plates at an interval; an included angle alpha is formed between the detection channel and a movement direction of the conveyor belt, and alpha is more than 0 degree and smaller than 90 degrees; and the detection channel is located at a photographing region of the line scanning camera. The appearance detection system can ensure that constant-speed movement in the axial and peripheral directions is kept when a material passes through a view field of the line scanning camera, so that an acquired image is linear, the boundary of the material is clear when the image is acquired, and the image processing difficulty is reduced; the material is driven by the belt to continuously move, and after front-section material supply is stopped, the material is not left on the section; the driving of the material is not influenced by other materials and can be suitable for any length, diameter and weight; and once if the material is stacked, the material automatically moves, so that the front-section material supply is slowed down or the speed of the belt is improved, the material can move out of a stacked region, and a material stacking fault is automatically removed.

Description

technical field [0001] The invention relates to the detection field of rod-shaped products and cylindrical products, in particular to a cylindrical product appearance detection system. Background technique [0002] Cylindrical or rod mechanical products are widely used in many fields of industry, such as rollers for needle bearings, zirconia ceramic ferrules for butt joints with optical fibers, and metal wool for the production of drills and milling cutters. Embryo and so on. Many products have strict quality requirements, and a comprehensive inspection of the appearance of the product is often required. Due to the large amount of cylindrical bar material, it is difficult for manual visual inspection to meet the speed and quantity requirements, so it is necessary to use machine vision equipment for automatic inspection. The mature cylindrical material machine vision inspection equipment on the market is divided into two categories: [0003] The first is to use multiple ar...
