Description

Technical Field

[0001] This utility model relates to the field of drain valve testing technology, specifically a drain valve testing device. Background Technology

[0002] A drain valve is a device used in toilets to control the discharge of water in pipes or containers. It is widely used in many fields such as industry and daily life. Its main function is to ensure the effective discharge of fluid and prevent excessive liquid or impurities from accumulating inside the equipment, thereby protecting the safe operation of the equipment. During the production process, the airtightness and half-discharge / full-discharge performance of the drain valve need to be tested, which requires a drain valve testing device.

[0003] However, existing drain valves are usually inspected manually, which is not accurate enough. The sealing of the drain valve relies on the human eye to observe the product dripping in water. However, it is difficult to observe the dripping of tiny leaks, or it may take a long time to detect NG (non-compliant) products. Moreover, workers are prone to false positives due to fatigue from long hours of work. In addition, the existing drain valves are not versatile and compatible enough, which means that the testing equipment cannot be used to change the matching fixture for products with different outer diameters, and cannot test various models of products.

[0034] Furthermore, such as Figure 4 and Figure 8 As shown, the surfaces of the test fixture 1201 and the jig 1202 are provided with a high compatibility mechanism 2. The high compatibility mechanism 2 consists of a clamping member 21, a connecting seat 22, a clamping plate 23, and an elastic locking member 24. Two sets of clamping members 21 are symmetrically arranged on the surface of the test fixture 1201. Two sets of connecting seats 22 are symmetrically installed on the surface of the test fixture 1201. The top of the connecting seat 22 extends into the interior of the clamping member 21 and rotates with the inner wall of the clamping member 21. A clamping plate 23 is installed on the inner wall of the clamping member 21. The surface of the clamping plate 23 contacts the surface of the jig 1202. An elastic locking member 24 is installed on the surface of the connecting seat 22. The elastic locking member 24 is engaged with the inner wall of the clamping member 21.

[0035] During implementation, the user rotates the two sets of clamping members 21 on the surface of the test fixture 1201. Under the action of the connecting seat 22, the clamping members 21 can move away from the fixture 1202. At this time, the clamping plate 23 on the inner wall of the clamping member 21 moves away from the surface of the fixture 1202, and the user can remove the fixture 1202 from the surface of the test fixture 1201. The replaced fixture 1202 is placed on the surface of the test fixture 1201, and the user then rotates the clamping plates 23 on the surface of the test fixture 1201. The clamping member 21 rotates on the surface of the connecting seat 22. When one side of the clamping member 21 moves above the fixture 1202, the fixture 1202 is pressed onto the surface of the test fixture 1201 by the combined action of the clamping member 21 and the clamping plate 23. At this time, the elastic clip 24 on the surface of the connecting seat 22 is engaged with the designated position on the inner wall of the clamping member 21, which can ensure the stability of the fixture 1202 when assembled on the surface of the test fixture 1201, so as to achieve the function of high compatibility of the testing equipment.

[0036] Working principle: In use, first place the equipment body 1 in the designated position, and manually place the product body 17 into the inside of the clamp 1105. Under the action of the circulating track 1102, the base 1104 and the clamp 1105 are conveyed, thereby driving the product body 17 placed on the surface of the clamp 1105 for loading. The clamp 1105 and the base 1104 are detachably connected. The user can replace the clamp 1105 with a suitable size according to the diameter of the product body 17 to meet the loading needs. Under the action of the half-row and full-row button press reset detection module 1103, the half-row and full-row button press reset detection of the product body 17 can be performed. Subsequently, the conveying mechanism 15 The first robotic arm module 1501 grips the product body 17 on the loading mechanism 11 and transports it to the surface of the airtightness testing mechanism 12 via the robotic arm track 1503. Specifically, the control box 10 controls the cylinder 1511 on the surface of the frame 1512 to work. Under the action of the cylinder 1511, the lifting seat 1513, the fixing plate 1514, the second gripper 1515, and the first gripper 1516 move downward to the required position. The drive component inside the fixing plate 1514 drives the second gripper 1515 to move to one side of the first gripper 1516. Under the combined action of the second gripper 1515 and the first gripper 1516, the product body 17 placed on the surface of the clamp 1105 is lifted. After clamping, the first robotic arm module 1501 moves on the surface of the robotic arm track 1503, moving it above the airtightness testing mechanism 12. It then places the product body 17, held between the second gripper 1515 and the first gripper 1516, at a designated position on the surface of the airtightness testing mechanism 12. Subsequently, the first robotic arm module 1501 resets, and the product body 17 is placed on the surface of the fixture 1202. Under the action of the airtightness testing machine 1200, the product body 17 undergoes vacuum testing to check its airtightness. Then, the second robotic arm module 1502 on the surface of the conveying mechanism 15 operates. Under the action of the airtightness testing mechanism 12, the product body 17 after surface inspection is clamped and placed inside the first half-drainage and full-drainage water volume testing mechanism 13. The next batch of product bodies 17 after being tested by the airtightness testing mechanism 12 is placed inside the second half-drainage and full-drainage water volume testing mechanism 14 through the second robotic arm module 1502. The product body 17 is tested inside the first half-drainage and full-drainage water volume testing mechanism 13 and the second half-drainage and full-drainage water volume testing mechanism 14. The NG / OK of the product body 17 is determined according to the liquid level height after the water tank 1304 is drained. According to the prior art, the water tank 1304 is equipped with a liquid level sensor with an accuracy of ±0.After the product body 17 has completed the internal testing of the first half-discharge and full-discharge testing mechanism 13 and the second half-discharge and full-discharge testing mechanism 14, the control box 10 controls the second robotic arm module 1502 on the surface of the conveying mechanism 15 to work. Under the action of the second robotic arm module 1502, the product body 17 inside the first half-discharge and full-discharge testing mechanism 13 is clamped and the product body 17 is moved. The product body 17 that is detected as NG is placed into the test air NG collection box 162 and the drainage NG collection box 163 respectively. Under the action of the guide frame 164, the product body 17 is guided. The product body 17 that is detected as OK is placed on one side of the 90-degree flip module 168 on the surface of the unloading rack 167. Under the action of the 90-degree flip module 168, the product body 17 is rotated 90 degrees. Then, the control box 10 controls the pushing module 165 to work. Under the action of the pushing module 165, the pushing plate 166 moves towards one side of the product body 17, pushing the product body 17 from the surface of the 90-degree flipping module 168 into the interior of the rotary air blowing dehydration module 169. The product body 17 rotates and blows air to remove water inside the rotary air blowing dehydration module 169. After the water is removed, the product body 17 is further pushed by the pushing plate 166 to the surface of the unloading conveyor module 1610. Under the action of the unloading conveyor module 1610, the OK product body 17 is conveyed to achieve the function of accurate detection by the testing equipment. This allows the testing equipment to achieve error-free detection. Even defects such as hair-like impurities causing incomplete sealing can be detected. At the same time, only manual loading is required, making the work comfortable and safe for workers.

[0037] Subsequently, due to the different diameters of the product bodies 17, the fixture 1202 needs to be replaced according to the diameter of the product body 17 to be tested. The user rotates the two sets of clamping members 21 on the surface of the test fixture 1201. Under the action of the connecting seat 22, the clamping members 21 can move away from the fixture 1202. At this time, the clamping plate 23 on the inner wall of the clamping member 21 moves away from the surface of the fixture 1202, and the user can remove the fixture 1202 from the surface of the test fixture 1201. The replaced fixture 1202 is placed on the surface of the test fixture 1201. The user then rotates the clamping members 21 on the surface of the test fixture 1201 respectively, so that the clamping members 21 are in... The surface of the connecting seat 22 rotates. When one side of the clamping member 21 moves above the fixture 1202, the fixture 1202 is pressed onto the surface of the test fixture 1201 by the combined action of the clamping member 21 and the clamping plate 23. At this time, the elastic clip 24 on the surface of the connecting seat 22 is locked at the designated position on the inner wall of the clamping member 21, which can ensure the stability of the fixture 1202 when assembled on the surface of the test fixture 1201, so as to realize the high compatibility function of the testing equipment. This allows the testing equipment to replace the matching fixture 1202 for products with different outer diameters, and the program can be quickly called up to be compatible with the testing of various models of product bodies 17, thus completing the use of the testing equipment.
