Problems solved by technology

[0004] This inspection machine with a grooved rotating disk has the following main disadvantages: 1) It is inconvenient to use, and each inspection machine can only detect parts of the same size. If the size of the parts changes, the orbit of the rotating disk and the feeder must be replaced. , this is a very troublesome thing; 2) the accuracy is not high, because the parts are suspended at the notch of the rotating disk by the big head, and the parts are free to swing in the groove, there is a certain gap, so when shooting to detect the diameter and length, When the screw pitch is used, the measurement accuracy will be affected by the distance error between the part and the camera lens, especially the big head of some screw parts is not perpendicular to the screw axis, and the effect is more obvious; 3) The speed is slow, and the parts are easy to get stuck in the rotation Because the parts enter the groove of the rotating disk one by one, sometimes the material will be jammed due to the poor cooperation between the rotating disk and the vibrating track, that is, the parts do not fully enter the groove of the rotating disk and the rotating disk is stuck, and such a structure , it is difficult to achieve high-speed operation; 4) The structure is complex and the cost is high

Embodiment

[0036] see figure 1, this embodiment provides a detection device for columnar products 7, including a feeding mechanism, a visual detection mechanism and a flow distribution mechanism. The detection device is used for the quality inspection of the columnar product 7, specifically, for detecting the length, outer diameter, and presence or absence of scars, burrs, etc. , the shape, depth and foreign matter of the head groove, the length, outer diameter, inner diameter and pitch of the threaded part, the sharp point and broken tail of the tail, etc.

[0037] In this embodiment, the visual detection mechanism includes a transparent plate 5, a control device and a camera assembly. The transparent plate 5 is docked with the discharge port of the feeding mechanism, the transparent plate 5 is inclined downward according to a preset angle, and is used to make the columnar product 7 move on the transparent plate 5 in a self-rotating manner, and the camera component is used to collect t...

Abstract

The invention provides a detecting device use for columnar products. The detecting device comprises a charging mechanism, a visual detecting mechanism and a distribution mechanism. The visual detecting mechanism comprises a transparent plate, a control unit and a camera assembly. The transparent plate is in butt joint with a discharging outlet of the charging mechanism and is inclined downwards by a preset angle and used for enabling the columnar products to move on the transparent plate in a rotating mode. The camera assembly is used for collecting the surface images of the columnar products. The distribution mechanism comprises a blowing unit, a qualified product collecting unit and a reject collecting unit. The blowing unit is arranged under the transparent plate and used for generating pulse airflow so as to blow rejects into the reject collecting unit. The detecting device provided by the invention is convenient to use, high in precision and speed, stable in operation and simple in structure.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a detection device for columnar products. Background technique [0002] Columnar products such as bolts and screws are common fasteners and connectors, and are widely used in various mechanical and electronic products. In order to ensure product quality, it is necessary to carry out quality inspection on columnar products. The traditional detection method is manual detection. Due to the high efficiency of the production line of columnar products, the speed of manual detection is slow, which seriously limits the output of columnar products. Therefore, some manufacturers carry out random inspection on products, and the way of random inspection will inevitably lead to the flow of substandard products into the market. [0003] With the development and progress of machine vision technology, visual inspection is applied to the quality inspection of columnar products. Taking screws...
