Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber seal ring appearance inspection, and particularly relates to a rubber seal ring appearance inspection equipment. BACKGROUND

[0002] The O-shaped rubber seal ring is a ring-shaped rubber seal ring with a circular cross section. The O-shaped rubber seal ring has simple structure, good sealing performance, small installation space, small friction, and is easy to manufacture. The O-shaped rubber seal ring is the most widely used extrusion sealing element and is mainly used for preventing liquid and gas medium leakage of mechanical parts under static conditions. Surface defects and wire diameter size are important technical performance indicators.

[0003] Traditional production of the O-shaped rubber seal ring is mainly formed by injection molding. Due to the characteristics of the rubber material, surface defects such as flow marks and misplacement may occur during the injection molding process. Such defects pose a potential threat to the sealing performance and service life of the seal ring. At present, the industry generally adopts an appearance inspection scheme based on visual detection, that is, an industrial camera is used to collect a surface image of the seal ring to identify defects. Although this scheme can be integrated with an automatic conveying line, it is limited by the single-surface imaging principle and can only detect a single surface of the seal ring. Manual intervention is required to complete the turning of the other surface and ensure that the position is appropriate (to avoid position deviation and inaccurate collection and detection), which leads to an efficiency bottleneck in the overall detection process.

[0026] The lifting plate 15 is rotatably connected with a turnover plate 29 opposite to the second conveying mechanism, a second motor 30 is installed on the bottom of the lifting plate 15, a drive shaft 31 is fixed to the output end of the second motor 30, and two drive rods 32 for driving the turnover plate 29 to rotate are fixed on the drive shaft 31.

[0027] The turnover plate 29 can turn over the rubber sealing ring, and is pushed to the first conveying mechanism by a pushing mechanism. The base 1 is provided with a mounting frame 2, and the mounting frame 2 is capable of reciprocating between the first conveying mechanism and the second conveying mechanism. When the camera 26 is opposite to the first conveying mechanism and the second conveying mechanism, the camera 26 is opposite to the rubber sealing ring, and the appearance of the front surface and the back surface of the rubber sealing ring can be collected.
