Abstract
Description
Technical Field
[0001] The utility model relates to the field of waterproof and airtight testing, in particular to an airtight waterproof testing mechanism. Background Art
[0002] Waterproofing is a very important performance indicator in electronic products, because water ingress into electronic products causes the greatest damage to the products, and this loss is irreversible. The current method for testing waterproof sealing is the water injection method. The disadvantage of the water injection method is that when testing in an open container, on the one hand, the pressure cannot be changed and the tester needs to stare at the container for a long time. The human eye is easily fatigued and there are judgment errors. On the other hand, it is impossible to accurately detect the waterproof level of the product. When testing in a closed container, although the pressure can be adjusted, the situation inside the container cannot be seen in real time. When the pressure change is small, the pressure sensor with low accuracy cannot detect it. At this time, a higher-precision pressure sensor is required for detection, which increases the cost. Utility Model Content
[0003] In view of the existing deficiencies, the utility model provides an airtight waterproof testing mechanism.
[0004] The technical solution adopted by the utility model to solve its technical problems is: an airtightness and waterproof testing mechanism, including a frame, on which a base, a control host, an electric air pump with an electromagnetic valve and a display screen are arranged, the top of the base is provided with a groove which is connected to the electric air pump through a ventilation pipe and can be injected with liquid, a movable sealing cover on the groove is provided with a top cover, a pressure sensor is arranged in the groove, and a camera is arranged on the top cover; the electric air pump, the display screen, the pressure sensor and the camera are all electrically connected to the control host.
[0005] Preferably, the frame is also provided with a driving mechanism for driving the top cover to move up and down.
[0006] Preferably, a shell with a accommodating cavity is provided on the frame, the control host and the electric air pump are both installed in the shell, and the display screen is installed on the shell.
[0007] Preferably, a through hole is provided on the groove wall of the groove, one end of the ventilation pipe is sealed and installed in the through hole, and the other end is connected to the electric air pump.
[0008] Preferably, the camera is a panoramic camera.
[0009] Preferably, the top cover is a sealing plug that can be matched and inserted into the opening of the groove, and a sealing ring is arranged on the side wall of the top cover and surrounds the top cover.
[0010] Preferably, the groove is a T-shaped groove, the sealing ring is arranged at a position where the side wall of the top cover is opposite to the upper part of the groove wall, and the top cover is sealingly connected to the upper part of the groove.
[0011] Preferably, a water outlet pipe is provided at the bottom of the groove, and a water outlet switch is provided on the water outlet pipe.
[0012] Preferably, a positioning mechanism for positioning the product to be detected is provided in the groove.
[0013] Preferably, the rack is also provided with a timer electrically connected to the control host.
[0014] The beneficial effect of the utility model is that the utility model utilizes the movable sealing setting of the top cover on the groove. When it is necessary to detect in an open state, the top cover is not covered on the groove, and the electric air pump does not need to inflate the groove, thus meeting the detection requirements under normal pressure. When it is necessary to detect in a sealed state where the pressure can be adjusted, the top cover is set on the groove to seal the groove, and then the air pressure in the groove is adjusted by inflating the electric air pump, thereby accurately detecting the waterproof level of the product. At the same time, the camera on the top cover is used to detect in real time whether bubbles are generated in the water in the groove. The camera solves the problem of being unable to detect when the air pressure change in the groove is not within the detection accuracy of the pressure sensor. The accuracy of the pressure sensor does not need to be too high, thereby reducing the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

A through hole is set on the groove wall of the groove 20, and one end of the ventilation pipe 21 is sealed and installed in the through hole, and the other end is connected to the air outlet of the electric air pump 4. The end of the ventilation pipe 21 connected to the groove 20 is set at the upper part of the groove 20. When a top cover 6 is set on the groove 20 and a test liquid is injected into the groove 20, the ventilation pipe 21 is between the top surface of the test liquid and the bottom surface of the top cover 6. The ventilation pipe 21 adopts a soft rubber tube; the movable sealing cover on the groove 20 is provided with a top cover 6, which needs to be sealed in a sealed state. When the product is used in an open state, the top cover 6 is moved and placed on the groove 20, so that the groove 20 is sealed, and then the air pressure in the groove 20 is adjusted by inflating the electric air pump 4, so that the waterproof level of the product can be accurately detected; when the product needs to be tested in an open state, the top cover 6 is not covered on the groove 20, and the electric air pump 4 does not need to inflate the groove 20, which meets the testing requirements under normal pressure, and the tester can also directly see the test situation in the groove 20; if the top cover 6 is set to a sealing plug of an elastically deformable plastic that is interference-fitted with the opening of the groove 20, or the top cover 6 is a plug that can match the plug A sealing plug is inserted into the opening of the groove 20, and a sealing ring 61 is arranged on the side wall of the top cover 6 around the top cover 6.
