Universal pneumatic fixture for visual inspection devices

Abstract

The invention provides a universal pneumatic fixture for visual inspection devices. The universal pneumatic fixture includes a bottom plate. A frame is fixed around the bottom plate. The thickness ofthe frame is greater than that of the bottom plate. A reflector is arranged around the inner side of the frame. The reflecting surface of the reflector tilts towards the upper center of the bottom plate. The reflecting surface of the reflector and the horizontal plane form an included angle Alpha. At least one adjustable clamping mechanism is arranged on the bottom plate. The image light information on the four sides of a product can be converted into information in the same direction and propagated. Through the cooperation of the general pneumatic fixture and a simple visual inspection devicefor single-direction detection, product image information in five directions at most can be obtained simultaneously. During line replacement, there is neither need for the visual inspection device tomake avoiding adjustment nor need to focus the lens. The time for line replacement is very short. The efficiency of visual inspection can be improved. Moreover, the production cost of the fixture islow, there is no need for a multi-direction multi-lens visual inspection device, and the cost of visual inspection can be reduced. The fixture can clamp most of the products, and is of high universality.

Description

technical field [0001] The invention relates to a clamp, and in particular discloses a general pneumatic clamp for a visual inspection device. Background technique [0002] Visual inspection device, also known as visual inspection device, visual inspection is to use machine instead of human eyes to make measurement and judgment, convert the ingested target into image signal through machine vision products, and send it to a dedicated image processing system, according to pixel distribution and brightness, Information such as color is converted into digital signals, and the image system performs various operations on these signals to extract the characteristics of the target. Vision inspection devices are widely used in industrial fields such as inspection, measurement, metrology, orientation, defect detection and sorting. [0003] With the continuous advancement of science and technology, the requirements for various parameters of the product are constantly increasing. There...

Problems solved by technology

To use this inspection device to detect different products, it is necessary to adjust the positions of the four lenses to place the product on the fixture of the stage. After installing the product, it is necessary to re-adjust the positions of the four lenses so that each lens can focus on the The four sides of the product to obtain a clear image, this kind of visual inspection device takes a long time to change the line, the work efficiency is low, and the cost of the visual inspection device is high, and the clamps in the existing visual inspection device only have the function of fixing the product
