A device for detecting whether the beam of a shelf is qualified through a fisheye lens group

Abstract

The invention discloses a device for detecting whether a goods shelf transverse beam is qualified or not through a fish-eye lens set. The device comprises a base, a conveyor belt, an approach switch, a stopping block, a pushing air cylinder, a measuring bracket, a portal frame, image photographing modules, a screw rod driving module, a pressing air cylinder and an overturning driving module, wherein two sets of the image photographing modules are arranged; the two sets of image photographing modules are arranged at the front and back ends of the measuring bracket respectively and are used for carrying out image acquisition on front and back two pairs of mounting holes of a workpiece to be detected; and each of the two sets of image photographing modules comprises an industrial camera, a parallel light source and a lens set. A field curvature principle of the lens sets is used for carrying out compression rate adjustment on photographed images of the mounting holes with the relatively far distance; when the mounting holes are closer to the middle, the compression ratio is higher; when the mounting holes are closer to the two ends, the compression ratio is lower; and when the distance between the two mounting holes in the photographed images is closer, the volume is correspondingly increased, so that image judgment can be conveniently carried out, the accuracy of a measured result is extremely improved and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of shelf beam detection, and more specifically relates to a device for detecting whether a shelf beam is qualified through a fisheye lens group. Background technique [0002] Modern large-scale production promotes the socialization, specialization, high mechanization and automation of industrial production, which requires that the supply of materials should be distributed in a timely, rapid and accurate manner, and also promotes the rapid development of storage technology. As a member of storage facilities, steel shelves are an indispensable part of modern logistics centers and distribution centers. Shelves are an important tool for warehouse modernization and efficiency improvement. Shelves generally refer to shelves for storing goods, and shelves are storage equipment for storing items. For example, in general stores, goods are often displayed on shelves. In order to improve the display of goods and facilitate load...

Problems solved by technology

[0005] However, when using an industrial camera to actually shoot, because the diameter of the mounting hole is small, usually less than 10mm, and the distance between the two mounting holes is usually more than 50mm, and the image taken by the industrial camera usually includes two mounting holes at the same end, The image taken in this way will appear to have too large a blank area, and the two installation holes that need to be photographed are very small, which is not conducive to the later image processing

If it is necessary to improve the shooting accuracy of the mounting hole, a high-precision camera is required, which will inevitably increase the cost of the equipment
