Description

Technical Field

[0001] This utility model relates to the field of network transformer testing technology, specifically a material tray circulation device for water withstand voltage testing of network transformers. Background Technology

[0002] Network transformers are crucial components in electronic devices, primarily used for network signal transmission, isolation, and impedance matching. They are indispensable in various network devices such as routers, switches, and network interface cards (NICs). The water withstand voltage test of a network transformer verifies its insulation performance and withstand voltage capability. Specifically, the transformer is submerged in water, and a certain voltage is applied using appropriate testing equipment to check for problems such as breakdown or leakage. If the test fails, using such a network transformer in equipment could lead to equipment malfunctions or even safety accidents. Therefore, this testing step is critical to ensuring the quality of network transformers.

[0003] Existing technologies have several problems. First, adjusting the magnets is cumbersome; manual adjustment is not only time-consuming but also makes it difficult to precisely control the magnet's height and position. This often results in the material tray being misaligned, causing positional deviations in the network transformer during testing and affecting the accuracy of the test data. Second, the design of the gripper device is also inadequate. Either the gripping is not stable enough, causing the transformer to wobble or even fall during testing; or the conductivity is poor, leading to frequent poor contact at the points of contact with the transformer, resulting in unstable test voltages and sometimes even no results. Therefore, we propose a material tray circulation device for water withstand voltage testing of network transformers. Utility Model Content

[0004] The purpose of this invention is to provide a material tray circulation device for water withstand voltage testing of network transformers, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material tray circulation device for water withstand voltage testing of network transformers, comprising a test circulation water tank mechanism and a test gripper assembly. The test gripper assembly is installed on both sides of the test circulation water tank mechanism. The test circulation water tank mechanism includes a circulation water tank, a support plate is provided below the circulation water tank, a magnet lifting mechanism is provided in the lower center of the circulation water tank, and quick-connect connectors and test coils are provided on both sides of the circulation water tank, and the quick-connect connectors and test coils are detachably connected to the circulation water tank.

[0006] Optionally, the magnet lifting mechanism includes a cylinder actuation plate disposed below the circulating water tank, a three-axis cylinder disposed below the cylinder actuation plate, the output end of the three-axis cylinder being detachably connected to the lower middle part of the cylinder actuation plate, a cylinder mounting plate being fixedly installed at the lower end of the three-axis cylinder, a plurality of first adjustment plates being disposed at the upper end of the cylinder actuation plate, and the first adjustment plates being detachably connected to the cylinder actuation plate, a second adjustment plate being disposed at the upper end of the first adjustment plates, the first adjustment plates and the second adjustment plates being fixedly connected by bolts, and a magnet being fixedly installed at the upper end of the second adjustment plate.

[0007] Optionally, a horizontal fine-tuning structure is provided between the second adjusting plate and the first adjusting plate.

[0008] Optionally, the test gripper assembly includes a support vertical plate, which is vertically arranged. A support horizontal plate is detachably installed on the upper end of the support vertical plate by bolts. Multiple mounting plates are detachably installed on the upper end of the support horizontal plate. A gripper cylinder is fixedly installed on the upper end of the mounting plate. An insulated gripper is fixedly installed on the output end of the gripper cylinder.

[0009] Optionally, the test gripper assembly further includes a first conductive copper plate, a second conductive copper plate, and a conductive sponge. The first conductive copper plate and the second conductive copper plate are respectively installed on the inner side of the insulating gripper, and the conductive sponge is attached to the surface of the first conductive copper plate and the second conductive copper plate.

[0010] Optionally, one end of the quick-connect fitting is connected to the inside of the circulating water tank, and the other end is used to connect to an external water circulation pipeline.

[0011] Optionally, the test coil is provided with multiple connectors for connection to the pins of the network transformer, and the test coil is electrically connected to an external test power supply.

[0012] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0013] In this application, the magnet lifting mechanism achieves automatic lifting and lowering of the magnet through a three-axis cylinder, with high telescopic precision. In addition, with the horizontal fine adjustment of adjustment plate 1 and adjustment plate 2, the position and height of the magnet can be precisely controlled to ensure that the material tray is firmly attracted and kept upright, thereby ensuring the accurate position of the network transformer during testing and greatly improving the accuracy of the test data.

[0014] This application employs a gripper cylinder to control the opening and closing of the insulating gripper, ensuring stable clamping force and preventing transformer shaking or falling. Simultaneously, a conductive copper plate and conductive sponge are placed inside the insulating gripper. The softness of the conductive sponge allows for tighter contact between the conductive copper plate and the transformer pins, reducing the possibility of poor contact, ensuring stable test voltage, and improving test reliability.

[0015] This application achieves water circulation through a test circulating water tank, which not only removes impurities from the water in a timely manner and keeps the water clean, but also keeps the water temperature stable, avoiding the impact of water temperature changes or water quality deterioration on the pressure resistance test results, and further improving the accuracy of the test.

[0016] This application allows for continuous testing of multiple transformers in a single tray, significantly reducing the testing time for individual transformers. This meets the needs of batch testing of network transformers in large-scale production and improves production efficiency. Attached Figure Description

[0023] Please see Figure 1-4This utility model provides a technical solution: a material tray circulation device for water withstand voltage testing of network transformers, including a test circulation water tank mechanism 1 and a test gripper assembly 2. The test gripper assembly 2 is installed on both sides of the test circulation water tank mechanism 1. The test circulation water tank mechanism 1 includes a circulation water tank 101. A support plate 102 is provided below the circulation water tank 101. A magnet lifting mechanism 103 is provided in the lower middle part of the circulation water tank 101. Quick connectors 104 and test coils 105 are provided on both sides of the circulation water tank 101, and the quick connectors 104 and test coils 105 are detachably connected to the circulation water tank 101.

[0024] In this embodiment, the support plate 102 is installed at the bottom of the circulating water tank 101. On the one hand, it supports the circulating water tank 101, allowing it to be stably fixed on the test platform. On the other hand, it also raises the circulating water tank 101 slightly, making it easier to install other components under the tank. The quick-connect connector 104 is installed on the side of the circulating water tank 101, with one end connected to an external water pipe and the other end leading into the circulating water tank 101. Through the quick-connect connector 104, water can continuously flow into the circulating water tank 101, while the water in the tank can also flow out, forming a cycle. This ensures that the water in the tank keeps flowing, which not only removes impurities from the water but also keeps the water temperature stable, preventing temperature changes from affecting the test results.

[0025] In this technical solution, the magnet lifting mechanism 103 includes a cylinder actuation plate 107 disposed below the circulating water tank 101. A three-axis cylinder 109 is disposed below the cylinder actuation plate 107. The output end of the three-axis cylinder 109 is detachably connected to the lower middle part of the cylinder actuation plate 107. A cylinder mounting plate 108 is fixedly installed at the lower end of the three-axis cylinder 109. A plurality of first adjustment plates 106 are disposed at the upper end of the cylinder actuation plate 107, and the first adjustment plates 106 are detachably connected to the cylinder actuation plate 107. A second adjustment plate 110 is disposed at the upper end of the first adjustment plates 106. The first adjustment plates 106 and the second adjustment plates 110 are fixedly connected by bolts. A magnet 111 is fixedly installed at the upper end of the second adjustment plate 110. A horizontal fine-tuning structure is provided between the second adjustment plate 110 and the first adjustment plate 106.

[0026] In this embodiment, when the three-axis cylinder 109 extends or retracts, the cylinder action plate 107 moves up and down accordingly. The second adjustment plate 110 is installed above the first adjustment plate 106, which facilitates fine-tuning and further improves the accuracy of adjustment. When the material tray is transported to the test position, the three-axis cylinder 109 extends, driving the adjustment plate, the adjustment plate and the magnet 111 to rise together until the magnet 111 attracts the material tray. After the test is completed, the three-axis cylinder 109 retracts, driving the magnet 111 and the material tray to descend together, so that the material tray can be transported away.

[0027] In this technical solution, the test gripper assembly 2 includes a supporting vertical plate 201, which is vertically arranged. A supporting horizontal plate 203 is detachably installed on the upper end of the supporting vertical plate 201 by bolts. Multiple mounting plates 202 are detachably installed on the upper end of the supporting horizontal plate 203. A gripper cylinder 204 is fixedly installed on the upper end of the mounting plate 202. An insulating gripper 205 is fixedly installed on the output end of the gripper cylinder 204. The test gripper assembly 2 also includes a first conductive copper plate 206, a second conductive copper plate 207, and a conductive sponge 208. The first conductive copper plate 206 and the second conductive copper plate 207 are respectively installed on the inner side of the insulating gripper 205. The conductive sponge 208 is attached to the surface of the first conductive copper plate 206 and the second conductive copper plate 207.

[0028] In this embodiment, the gripper cylinder 204 is the power source for the gripper section. It is connected to the insulating gripper 205, and the opening and closing of the insulating gripper 205 is controlled by the compression of compressed air. The insulating gripper 205 is the component that directly contacts the network transformer. Its material is insulating material, which can prevent leakage during testing and ensure test safety. At the same time, in order to make the contact between the conductive copper plate and the network transformer tighter, a layer of conductive sponge 208 is attached to the surface of the conductive copper plate. The conductive sponge 208 is soft and is slightly compressed when the gripper clamps the transformer, thus filling the gap between the copper plate and the transformer and ensuring good conductivity.

[0029] In this technical solution, one end of the quick-connect connector 104 is connected to the inside of the circulating water tank 101, and the other end is used to connect to the external water circulation pipeline.

[0030] In this technical solution, the test coil 105 is provided with multiple connectors for connecting to the pins of the network transformer, and the test coil 105 is electrically connected to an external test power supply.
