Description

Technical Field

[0001] The utility model relates to the technical field related to product visual inspection, and in particular to a product loading and unloading visual inspection device. Background Art

[0002] Visual inspection is to use machines to replace human eyes to make measurements and judgments. Visual inspection refers to the process of converting captured targets into image signals through machine vision products, transmitting them to a dedicated image processing system, and converting them into digital signals based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment action on site based on the results of the judgment. It is a valuable mechanism for production, assembly or packaging. It has inestimable value in detecting defects and preventing defective products from being delivered to consumers.

[0003] After massive searches, it was found that the prior art publication number is CN215031314U, which discloses a conveyor belt for an aluminum cover processing visual inspection machine, including: the base, which is an existing electric control box structure, provides power to the device, and plays a role of fixed support for the device, and a conveyor belt is installed on the upper end of the base; fixed rods, which are installed on the outer surface of the conveyor belt at equal intervals, and the outer surface of the fixed rods is provided with a cross plate; a waste hopper, which is provided on the outer surface of the conveyor belt, and the outer surface of the conveyor belt is provided with a cylinder. The conveyor belt for the aluminum cover processing visual inspection machine, when the device is in use, when the camera detects an unqualified workpiece, the user can energize the cylinder so that the cylinder drives the push plate to move, thereby pushing the workpiece into the waste hopper for centralized storage through the push plate, avoiding the workpieces from being mixed together and inconvenient for the user to distinguish, and at the same time facilitating the user to centrally process the unqualified workpieces.
