Description

Technical Field

[0001] The present application relates to the technical field of automated inspection production lines, and in particular to a hardness and size inspection device for loading and unloading workpieces. Background Art

[0002] General machine vision system: camera, lens, light source, motion system, visual industrial inspection is generally divided into workpiece size measurement and positioning, surface defect detection, and various logo detection and identification, etc. Size measurement mainly detects the length, width, and height of the object. The most common is the two-dimensional size (width and height) detection of the object. Surface defect detection is mainly the area with uneven physical or chemical properties on the surface of the object. The most common ones are scratches on the surface of metal or plastic products (such as scratches on the surface of mobile phone cases / screens), spots and holes (such as missing solder joints on PCB boards or more solder joints on the surface), color difference, dirt, and damage on the surface of paper, indentations and bulges on the surface of paper products, impurities, damage, stains, and flatness on the surface of non-metallic products such as glass. , In particular, it involves a device for detecting the hardness and size of workpieces during loading and unloading.

[0003] However, there are still some shortcomings in its actual use. For example, when the current testing equipment conducts a comprehensive inspection on the workpiece during loading and unloading, the workpiece needs to be immediately converted from a moving state to a static state, which leads to the workpiece being easily displaced during the fixing process and uneven force when fixed. As a result, various data are prone to errors in the subsequent testing process, thereby affecting the equipment's judgment of the workpiece's performance, and thus failing to effectively control the product's factory quality. Summary of the invention

[0004] In order to improve the stability of the workpiece during inspection and to improve the accuracy of inspection, the present application provides a hardness and size inspection device for loading and unloading workpieces. By setting a fixed clamping plate and a fixed side plate as well as an arc-shaped clamping port and a side guide plate, the operator slides the workpiece through the side guide plate and fixes it inside the arc-shaped clamping port and the adapter port between the fixed clamping plate and the fixed side plate. The workpiece is fixed from the left and right sides by two groups of structures, and an electric telescopic rod is used to drive the fixed clamping plate to rotate and press toward one side of the workpiece, thereby effectively ensuring the stability of the workpiece during the fixing process, and simultaneously locking the workpiece through the two arc-shaped clamping ports and the adapter port to ensure that its center of circle is concentrically distributed with the center of circle between the arc-shaped clamping port and the adapter port, thereby improving the fixing accuracy of the workpiece while ensuring its stability, avoiding problems such as displacement and loosening during the fixing and inspection process, and simultaneously The overall hardness and size of the workpiece can be effectively measured through the detection equipment inside the base of the equipment. By setting an electric telescopic rod, a reset spring and a fixed rotating shaft, first, when the electric telescopic rod retracts, the reset spring will use its own reverse elastic force to drive the electric telescopic rod to quickly reset, thereby ensuring its automation and work efficiency. At the same time, the fixed rotating shaft on one side of the fixed splint will rotate inside the rotating circular hole on the operating table, ensuring the flexibility of the fixed splint during the locking and releasing process. Finally, the fixed splint returns to its original position, ready to clamp and detect the next workpiece, further improving the automation of the equipment and the overall work efficiency, so as to solve the problems raised in the above background technology.
