Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection devices, in particular to a small workpiece detection platform with a built-in laser measuring instrument. Background Art
[0002] Dimension measurement is the most common application industry of machine vision technology, especially in the automated manufacturing industry. Machine vision is used to measure various dimensional parameters of workpieces, such as length measurement, circle measurement, angle measurement, arc measurement, area measurement, etc. The actual size of the product is often indispensable, but due to the complexity of the surface of the object or the limitation of objective physical conditions, it may not be available. Machine vision detection technology can handle such problems well and measure various dimensional parameters of workpieces, such as length measurement, circle measurement, angle measurement, line arc measurement, area measurement, etc. The automatic detection and judgment system based on machine vision can automatically measure and judge the inner and outer dimensions of various models of apertures, bridge width, slot width and other parameters, and detect the basic geometric features of the relevant areas of the workpiece;
[0003] Currently, workpieces are usually inspected manually using micrometers, vernier calipers, feeler gauges, etc. to measure with the naked eye. However, uneven force is prone to occur during long-term measurements, causing the caliper to be tilted. In addition, such measurement methods have low measurement accuracy and slow speed, and cannot meet the needs of large-scale automated production. At the same time, during the laser detection process, it is easily affected by light and dust, causing the detection accuracy to deviate.
[0004] In view of this, we propose a small workpiece inspection platform with a built-in laser measuring instrument. Utility Model Content
