Description

Technical Field

[0001] This utility model relates to the technical field of sealing test equipment, and in particular to a sealing test equipment for automotive gaskets. Background Technology

[0002] Automotive gaskets are materials or parts used to prevent fluids or solid particles from leaking between adjacent mating surfaces and to prevent external impurities such as dust and moisture from entering the interior of machinery and equipment.

[0003] For example, the authorization notice number "CN212845985U" is titled "Detection Device for Missing Automotive Sealing Gaskets." While it applies pressure to the product components and uses a pressure sensor to determine if any components are missing by monitoring the pressure drop, the device operates normally if no components are missing and the pressure drop exceeds the set range. If a component is missing, the pressure sensor detects a pressure drop exceeding the set range, triggering an alarm and stopping operation. This method allows operators to effectively determine if components are missing, ensuring product quality. However, this detection device lacks a conveying device, requiring manual picking of automotive gaskets, reducing detection efficiency. Furthermore, the device lacks a sorting device, necessitating manual sorting, increasing labor load and reducing production efficiency. Utility Model Content

A pressurizing fan 12 is located on the upper surface of the second frame 10. An air passage 13 is located on the middle surface of the sealing test block 11.

A third mounting block 18 is located at the rear end of the upper surface of the sealing test block 11. A sealing test device is located on the lower surface of the third mounting block 18. Two second infrared emitters 19 are located on the lower surface of the sealing test device. There are two receiving slots 20 on the upper surface of the sealing test block 11 corresponding to the second infrared emitters 19. A second infrared receiver 21 is located on the lower inner wall of each of the two receiving slots 20. The infrared rays emitted by the second infrared emitters 19 are received by the second infrared receivers 21 and then fed back to the control terminal. The upper rear surface of the first frame 1 is provided with a fourth mounting block 22 on both sides. The upper surface of the two fourth mounting blocks 22 is provided with a sorting device.

After the compressed air pressure is stable, stop the pressure blower 12, and detect whether there is a pressure drop through the air pressure sensor 17, so as to detect the sealing performance of the gasket body 5. After the test is completed, reverse-start the third cylinder 30 to make the third telescopic rod 31 shorten, and then drive the sealing slider 32 to move upward to make the sealing slider 32 separate from the gasket body 5, and the detection is completed; for the set sorting device, when the gasket body 5 is tested, if the air pressure value transmitted by the air pressure sensor 17 drops to the specified range value, this gasket body 5 is a qualified product, start the second cylinder 27 on one side to make the second telescopic rod 28 extend, and push the gasket body 5 into the recycling box 23 on the other side through the second push block 29.
