Description

Technical Field

[0001] The utility model relates to the technical field of plastic product detection, in particular to a black spot inspection device for plastic products. Background Art

[0002] Plastic is a material widely used in the manufacture of various plastic products. It is a product formed by processing high-molecular compounds. It has the characteristics of low density, good toughness, corrosion resistance, and easy processing and molding. Plastic also has good insulation properties and can be used for the packaging of electronic devices.

[0003] During the production process of plastic products, it is inevitable that some plastic products will contain black spots. Black spots are usually composed of carbides, foreign impurities, broken metal particles in the equipment, or undispersed speckled crystals of masterbatch. The presence of these black spots may seriously affect the appearance and quality of the products. Therefore, black spot inspection of plastic products can effectively avoid these problems and ensure that the appearance and quality of the products meet the standards. At present, the existing black spot inspection of plastic products is mostly completed by manual observation with the naked eye. After the black spots are manually discovered in the plastic products, they need to be manually removed from the conveyor belt, which will undoubtedly increase the labor intensity. In addition, the efficiency of this inspection is also low, which in turn affects the production efficiency of the products. Utility Model Content

[0004] The purpose of the present invention is to provide a black spot inspection device for plastic products to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0012] 1. The utility model cooperates with a CCD visual camera, a cylinder, a kick plate and a material guide structure to capture image information of the bottle cap surface through the CCD visual camera, and uses a computer's image processing algorithm to process and analyze the image. During the image processing process, the computer will analyze and judge according to preset defect characteristics. If defects such as black spots are detected, the computer will start the cylinder, and the cylinder will kick out unqualified plastic products through the kick plate and export them through the material guide structure. Compared with the existing manual visual inspection method, the utility model has higher inspection efficiency and lower labor intensity.

[0013] 2. The utility model is provided with an electric telescopic rod, a slider and a trough body. The electric telescopic rod drives the slider to move upward or downward in the trough body, and then drives the CCD vision camera to rise or fall.
