The device provided by the invention utilizes the optical fibers to detect positions of the mounting holes, and can detect whether the parallel light source works normally only by utilization of the single-beam optical fibers, thereby greatly reducing cost of equipment, the detection process is convenient, and the detection precision is high.

Description

technical field [0001] The invention relates to the field of shelf crossbeam detection, in particular to a device for detecting the position of a shelf crossbeam mounting hole by rotating a single optical fiber. 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 facili...

Problems solved by technology

For example, in general stores, goods are often displayed on shelves. In order to improve the display of goods and facilitate loading and unloading of goods, a large number of different components are used. Among them, whether the length of the shelf beam is qualified or not directly affects the ability of the shelf Normal installation will affect the final quality of the shelf

[0003] The shelf beam is usually a sheet metal part with a certain length, and a pair of mounting holes are opened at both ends. The length of the shelf beam is very high, and the mounting holes must be set at the designated positions; usually the shelf beam needs to be stamped during the production process. Forming, punching, and cutting are three processes, and the inspection of the shelf beam needs to be measured after all processes are completed; since the length and installation hole position detection is carried out after all processes are completed, if one of the processes fails , resulting in unqualified shelf beams, it cannot be fed back to the production process in time, and the consequence is a series of unqualified products that follow the unqualified products

[0004] In the detection process of shelf beams, the common method is to manually detect the length of the shelf beams and the position of the installation holes. The detection process is cumbersome, the detection accuracy is high, and the manpower consumption is relatively large. Usually, only manual spot checks are used for detection.

If the method of image acquisition is used, the position of the mounting hole of the standard part is first photographed to obtain a standard image, and then the test part is photographed, and the obtained picture is image-processed with the standard image, and whether the test part is qualified by comparison Conclusion; Although this measurement method gets rid of the limitations of traditional manual measurement, the cost of industrial cameras is relatively high, and a computer is required for image processing, which will inevitably prolong the detection time, which is not conducive to reducing equipment costs and speeding up detection.
