Description

Technical Field

[0001] The present invention relates to the technical field of rubber product detection, and in particular to a detection device for rubber products. Background Art

[0002] Rubber products are widely used in industries such as automotive, electronics, electrical engineering, and construction, and their quality directly impacts product performance and service life. To ensure the quality of rubber products, particularly their hardness and appearance, traditional testing methods typically rely on manual inspection or single mechanical testing equipment. However, existing testing equipment often suffers from insufficient accuracy, low efficiency, and the inability to perform multiple tests simultaneously, making it unable to meet the high quality control standards required in large-scale production.

[0003] Hardness is a key physical property of rubber products, directly affecting their elasticity, durability, and performance. Traditional hardness testing typically relies on manual measurement. While this method provides adequate results, it can easily lead to data instability and inaccuracy due to manual manipulation. Furthermore, the unique geometry of annular rubber products makes it difficult to ensure comprehensive and uniform hardness testing accuracy using traditional methods.

Common defects include surface scratches, bubbles, cracks, etc. These defects may affect the function and appearance quality of rubber products.

The cylinder arm of the hydraulic cylinder 3 607 continues to drive the motor 5 609 to move downward, and the driving member 612 is separated from the contact state with the gear 5 617. The driving member 612 contacts the connecting groove 508 on the gear 1 507. The limiting member 610 is inserted into the gear 5 617. The driving member 612 drives the gear 1 507 to rotate, and the gear 1 507 drives the inner gear ring 506 The inner gear ring 506 rotates, and the connecting ring 503 rotates through two sets of arc-shaped sliding plates. The connecting ring 503 drives the rotating ring 502 to rotate, and the rotating ring 502 drives the sliding support 513 to move closer or disperse. When the sliding support 513 moves closer, the rubber product is clamped. When the sliding support 513 disperses, the rubber product is released. During the rotation of the rotating ring 502, the appearance of the outer ring of the rubber product is inspected by a visual inspection instrument 524. The inspection data is transmitted to the computer. When it is found that the outer ring of the rubber product is If a problem occurs with the appearance, start the small air pump 519 and motor 4 520. The output end of motor 4 520 drives gear 3 516 through gear 2 515. Gear 3 516 drives connecting piece 522 through rotating rod 1 523. Connecting piece 522 drives spray port 521. The paint in storage box 518 enters spray port 521 through connecting pipe 517 through small air pump 519. The problem area on the outer ring of the rubber product is marked through spray port 521. The rubber product is then removed and reset.
