Visual detection device capable of reducing visual detection misjudgment rate and detection method thereof

Abstract

The invention discloses a visual detection device capable of reducing the misjudgment rate of visual detection and a detection method thereof. The visual detection device comprises a vertical plate, a height adjusting structure, a transverse adjusting structure, a plane angle adjusting structure, an inclination adjusting structure, a guiding and stabilizing structure and a product positioning structure. A mounting plate is welded to the bottom end of the left side wall of the vertical plate, a reinforcing rib is arranged at the vertical joint of the mounting plate and the vertical plate, and a mounting groove is formed at the left side of the bottom surface of the mounting plate; penetrating holes are symmetrically formed at the left side of the wall body of the mounting plate, and fixing screw rods are arranged in the penetrating holes in the wall body of the mounting plate. According to the visual detection device capable of reducing the visual detection misjudgment rate and the detection method thereof, the detection judgment can be prevented from being influenced by too high conveying speed, the external characteristic specifications of a product are comprehensively acquired from different angles, supporting and guiding stability in the moving process is provided, shaking during acquisition is avoided, pictures of different external characteristic specifications of the product can be acquired, and later accurate comparison is facilitated, so that misjudgment is comprehensively reduced.

Description

technical field [0001] The invention relates to the technical field of visual detection equipment, in particular to a visual detection device and a detection method for reducing the misjudgment rate of visual detection. Background technique [0002] Visual inspection is a valuable mechanism for production, assembly or packaging that uses machines instead of human eyes for measurement and judgment. It has inestimable value in the function of detecting defects and preventing defective products from being delivered to consumers, but There are many problems in the traditional visual inspection equipment. It cannot accurately determine the arrival of the product, resulting in the product being conveyed at a high speed all the time. It cannot reduce the transmission speed of the product conveying line. According to the external feature specifications of the product, the image acquisition has strong limitations. It is impossible to avoid the detection and judgment due to the limite...

[0002] Visual inspection is a valuable mechanism for production, assembly or packaging that uses machines instead of human eyes for measurement and judgment. It has inestimable value in the function of detecting defects and preventing defective products from being delivered to consumers, but There are many problems in the traditional visual inspection equipment. It cannot accurately determine the arrival of the product, resulting in the product being conveyed at a high speed all the time. It cannot reduce the transmission speed of the product conveying line. According to the external feature specifications of the product, the image acquisition has strong limitations. It is impossible to avoid the detection and judgment due to the limited position of the image acquisition. It cannot provide stable support and guidance during the movement process. It is possible to collect pictures of different external feature specifications of products in advance to achieve accurate comparison in the later stage, resulting in many detection misjudgment factors. Therefore, a visual inspection device and a detection method that can reduce the misjudgment rate of visual inspection can solve such problems It is imperative to realize
