Description

Technical Field

[0001] The utility model relates to the field of pressing devices, in particular to a pressing device with a visual detection function. Background Art

[0002] Visual inspection is to use machines to replace human eyes for measurement and judgment. Visual inspection refers to the use of machine vision products (i.e. image capture devices, divided into CMOS and CCD) to convert the captured target into image signals, which are transmitted to a dedicated image processing system. According to pixel distribution, brightness, color and other information, they are converted into digital signals. The image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment action on site according to the results of the judgment. It has immeasurable value in detecting defects and preventing defective products from being delivered to consumers. In the production process of automotive carpets, after the pressing device presses the carpet, the carpet is photographed by an industrial camera, and the photographed image is converted into an image signal. Through the image processing system, comparative analysis is performed to judge the pressing effect.

[0003] However, the carpet is divided into a front side and a back side. The back side of the carpet fits against the workbench and is not easily photographed by an industrial camera, resulting in a lack of back side information in the image signal. The judgment result is very likely to be biased. For example, a Chinese utility model type patent with a public document number of CN214584836U discloses a visual inspection device that is easy to adjust. In the utility model, a limit pin can be pushed out by a spring arranged in a supporting rod. After the limit pin is pushed out, it can be connected to a first positioning hole and a second positioning hole, thereby unfolding the first telescopic rod and the second telescopic rod to facilitate adjustment of the position of the detection lens. Then, the back side of the car carpet is shielded by the workbench of the pressing plate device. It is impossible to capture the back side image of the carpet by simply adjusting the position of the camera lens. The car carpet must be turned over for shooting. For this reason, the present application proposes a pressing device with a visual inspection function. Utility Model Content
