[0002] At present, in the production process of auto parts, the junction of metal parts and rubber parts needs to be sprayed with special adhesives and coatings. According to the process arrangement, it is divided into two types of coatings for two spraying operations and dried; during this period, it is not allowed to touch them with hands. Therefore, if the spray gun is clogged or the coating is short of material, there may be spray leakage; especially if the first layer of spraying is missed or less sprayed, it is not found in time, and it is randomly covered by the second layer of spraying, resulting in residual residue that is not immediately noticed. Defective products are transferred to the subsequent process; in order to ensure that the products have been sprayed twice, it is necessary to inspect the product production and spraying process; the existing inspection method directly sets up an industrial camera near the spray gun for shooting, but it is limited to the outer ring spraying inspection, and the inner Circle spray detection is limited by the diameter of the inner hole and cannot be detected, or it can only be photographed at a 45-degree angle (the product rotates during the photographing). Due to the difference in product height, the viewing angle is blind, so defective products cannot be detected, and the production cost is greatly increased. Reduced detection efficiency, while reducing production efficiency

The invention discloses a detection device for sprayed products, comprising: a driving assembly, including a first connecting piece, one end of the first connecting piece is connected with the detection assembly; a detection assembly, including a detection feedback piece, the detection feedback The device includes an imaging device and a signal capturing device, the signal capturing device is placed under the imaging device, and a signal is fed back to the imaging device through the signal capturing device. The invention can ensure that more production pieces can be detected when detecting products, reduce blind areas in detection, and increase detection efficiency through telescopic guide rods.
Description
technical field [0001] The invention relates to the technical field of qualified detection of sprayed products, in particular to a device capable of distinguishing and detecting sprayed products. Background technique [0002] At present, in the production process of auto parts, the junction of metal parts and rubber parts needs to be sprayed with special adhesives and coatings. According to the process arrangement, it is divided into two types of coatings for two spraying operations and dried; during this period, it is not allowed to touch them with hands. Therefore, if the spray gun is clogged or the coating is short of material, there may be spray leakage; especially if the first layer of spraying is missed or less sprayed, it is not found in time, and it is randomly covered by the second layer of spraying, resulting in residual residue that is not immediately noticed. Defective products are transferred to the subsequent process; in order to ensure that the products have b...
