Description

Technical Field

[0001] The utility model relates to the technical field of visual inspection, in particular to a high-precision visual inspection platform. Background Art

[0002] Visual inspection involves replacing the human eye with machines for measurement and judgment. This involves using machine vision products (i.e., image capture devices, available in CMOS and CCD formats) to convert captured objects into image signals. These signals are then transmitted to a dedicated image processing system, which converts them into digital signals based on pixel distribution, brightness, color, and other information. The imaging system then performs various operations on these signals to extract the object's features and, based on the resulting analysis, controls the operation of on-site equipment. This is a valuable mechanism used in production, assembly, and packaging. Its value lies in detecting defects and preventing defective products from reaching consumers.

[0003] When visual inspection is performed on a product, the product needs to be placed on the inspection platform and then inspected with the visual inspection module. However, the existing visual inspection platform can only perform a single static placement when placing the product, and then use the drive mechanism to drive the visual camera for rotation inspection. This limits the inspection angle of the product and cannot perform high-precision inspection.

Then, the second X-axis linear module 93 is started to drive the slide 92 to slide along the support frame 3 91 until it slides to the bottom of the vision module 5, and then visual inspection can be carried out;
