Description
Technical Field
[0001] The utility model relates to the technical field of electrostatic discharge, in particular to an electrostatic discharge testing system. Background Art
[0002] Electrostatic discharge testing uses a simulator to simulate the effects of human static electricity on equipment. Currently, ESD testing for domestic energy metering products is performed manually, resulting in low efficiency, high labor intensity, and significant safety risks. Furthermore, a wide range of existing energy metering products, including single-phase meters, three-phase direct meters, three-phase inductive meters, and terminals, all require ESD testing. With numerous testing options, manual testing cannot guarantee a standardized and uniform testing process, and consequently, the accuracy of measurement results cannot be guaranteed.
[0003] Existing domestic ESD testing equipment relies on manual testing, using a discharge gun tip to perform ESD tests on various locations on an object according to GB17626.2. Some companies are attempting to automate this testing, primarily using industrial robots to replace humans and employ ESD tools to perform direct discharges on the surface of energy metering equipment. These tests lack indirect and air discharge procedures, and the discharge process is not strictly adhered to GB17626.2, resulting in unreliable test results.
[0004] The utility model, with publication number CN217981666U, discloses an electrostatic discharge immunity test device, comprising: a workbench, an electrostatic gun, a controller, and a horizontal coupling plate, a vertical coupling plate, a movable mechanism, and a gun tip placement compartment mounted on the insulating tabletop of the workbench. The horizontal coupling plate is used to place an electric energy meter, and the vertical coupling plate is located to the side of the horizontal coupling plate. The electrostatic gun is connected to the movable mechanism, which drives the electrostatic gun to move and rotate within a working range. The horizontal coupling plate and the gun tip placement compartment are both located within the working range. The gun tip placement compartment is used to place the gun tip and provide a placement location. The gun tip placement compartment, the electrostatic gun, and the movable mechanism are all connected to and controlled by the controller. However, the above-mentioned electrostatic discharge immunity test device can only perform a single electrostatic discharge test on an electric energy meter. Utility Model Content

[0076] The transfer device 2 is connected to the second clamp 42 for clamping the tooling power-on device 7 to power on the first object power-on tooling 53 or the second object power-on tooling 63 .
[0077] The clamping device 421 is used to press down and fix the first object power-on device 5 or the second object power-on device 6 when the three-phase electricity meter is connected to the first object power-on device 5, or when the single-phase electricity meter is connected to the second object power-on device 6, to prevent the first object power-on device 5 or the second object power-on device 6 from moving when the connection is powered on.

[0083] In this embodiment, the first object power-on fixture 53 is used to position and power up a three-phase energy meter. The first power-on socket 531 is a dedicated three-phase energy meter socket, and the first power terminals 532 are standard terminals designed to mate with connectors 71 using a standard interface. Connecting the power-on terminal of the three-phase energy meter to the first power-on socket 531, and connecting the first power terminals 532 to the fixture power-on device 7, transmits power and signals to the first power-on socket 531. The first power-on socket 531 directly inputs the power and signals to the three-phase energy meter placed within the first object power-on device 5.
[0084] The reason why the first object power-on device 5 and the second object power-on tooling 63 need to be set separately is that the power-on interfaces of objects such as single-phase electricity meters and three-phase electricity meters are different, and corresponding special meter sockets need to be set to cooperate with the power-on interfaces of different objects. The present invention sets different power-on toolings accordingly, sets standard power terminals and corresponding special meter sockets on the power-on tooling, and there is no need to set multiple tooling power-on devices 7 to power on single-phase electricity meters, three-phase electricity meters and other objects respectively. The connector 71 with a standard interface on the power-on device 7 can be connected to the standard power terminals on different power-on toolings, and the power-on of different objects such as single-phase electricity meters and three-phase electricity meters can be realized.
[0085] The first limiting assembly 533 is respectively provided on the inner side walls opposite to the first object electrical device 5, and is used to limit the backward movement of the three-phase electric energy meter, complete the limiting and fixing of the three-phase electric energy meter, and realize the combined binding of the three-phase electric energy meter and the first object electrical device 5. The first limiting assembly 533 includes a fixing seat 5331, a reset spring 5332, and a limiting block 5333. When the three-phase electric energy meter needs to be limited, the limiting block 5333 is pressed down to make it contact the end of the three-phase electric energy meter away from the first upper electrical seat 531, preventing it from falling out of the first upper electrical seat 531. Under the downward pressure of an external force, the limiting block 5333 rotates upward under the action of the reset spring 5332, realizing the release of the limit, and releasing the binding of the three-phase electric energy meter and the first object electrical device 53.
[0086] The tooling power-on device 7 is equipped with a connector 71, which uses a standard interface to power various tooling types, including single-phase, three-phase, and terminal devices. Guide pin holes 72 are provided at each end of the connector 71. Guide posts are provided at corresponding positions on the first power terminal 532 or the second power terminal 632. The guide pin holes 72 cooperate with the guide posts to accurately connect the connector 71 to the first power terminal, achieving precise positioning.
[0087] See also Figure 6 In some embodiments of the present invention, the first object power-on device 5 further includes a first positioning device 54 , a first positioning detection component 55 and a plurality of first clamping blocks 56 arranged around the first object power-on tooling 53 .
[0088] A plurality of first latches 56 are provided around the first object loading fixture 53. A first positioning device 54 is provided at one end of the first object loading fixture 53. The first latches 56 cooperate with the first positioning device 54 to limit the position of the first object loading fixture 53, preventing the transfer device 2 from damaging the positioning accuracy of the first object loading fixture 53 during the process of placing an object on the first object loading fixture 53. A first positioning detection component 55 can detect the presence of an object or the first object loading fixture 53 to determine the accuracy of the workflow node.
[0089] See also Figure 9 and 10 In some embodiments of the present invention, the second object electrical tooling 63 includes a second upper electrical seat 631 , a second electrical terminal 632 and a second limiting component 633 , and the second upper electrical seat 631 is electrically connected to the second electrical terminal 632 .
[0090] Second object power-on device 6 is used to position and power up a single-phase electricity meter. It includes a second frame 61, a second pneumatic device 62, a second object power-on tool 63, a second positioning device 64, and a second positioning detection assembly 65. Second object power-on tool 63 is similar in structure to first object power-on tool 53, including a second power-on seat 631, a second power terminal 632, and a second position-limiting assembly 633, which completes the power-on operation of the single-phase electricity meter. Second position-limiting assembly 633 shares the same structure and principle as first position-limiting assembly 533.
[0091] In this embodiment, the movements of the object clamping jaw 321 , the positioning device clamping jaw 322 , the pressing device 421 , and the tooling power-on device clamping jaw 422 are all driven by the second pneumatic device 62 or the first pneumatic device 52 .
[0092] See also Figure 9 In some embodiments of the present invention, the second object power-on device 6 further includes a second positioning device 64 , a second positioning detection component 65 and a plurality of second clamping blocks 66 arranged around the second object power-on tooling 63 .
[0093] A plurality of second latches 66 are provided around the second object mounting fixture 63. These second latches 66 cooperate with the second positioning device 64 to limit the position of the second object mounting fixture 63, preventing the transfer device 2 from damaging the positioning accuracy of the second object mounting fixture 63 during the placement of the object on the second object mounting fixture 63. A second positioning detection assembly 65 can detect the presence of the single-phase electric energy meter and the second object mounting fixture 63, assisting in control.
[0094] See also Figure 1-12 Taking a three-phase electric energy meter as an example, the working process of this utility model is as follows:
[0095] The three-phase electric energy meter is transported to the side of the adjacent transfer device 2 through the conveyor line 1. After being stopped and lifted to position, the first clamp 32 is picked up by the transfer device 2.
[0096] After the transfer device 2 picks up the first clamp 32 , it clamps the three-phase electric energy meter to be tested through the object clamping claws 321 and places it on the first object electrical tool 53 .
[0097] The transfer device 2 pushes the three-phase energy meter to be tested toward the first upper electrical seat 531 and, through the first limit assembly 533, positions it so that the three-phase energy meter is firmly secured within the first electrical fixture 53, thereby completing the connection between the three-phase energy meter and the first electrical fixture 53. The transfer device 2 then places the first electrical fixture 53 on the test bench 9 using the first fixture 32.
[0098] The transfer device 2 uses the second clamp 42 to clamp the tooling power-on device 7 and insert it into the first power terminal 532 provided on the first object power-on tooling 53 to power on the first object power-on tooling 53 and the three-phase electric energy meter.
[0099] According to the national standard GB17626.2, the transfer device 2 uses an indirect discharge gun 33 for indirect discharge and direct discharge, and an air discharge gun 43 for air discharge. A wireless electrostatic gun can be used here, and a thread tightening machine or a plug-in device can be used to replace the gun head to achieve different electrostatic discharge requirements.
[0100] During the test, the detection device 8 records the entire test process and detects the status of the three-phase electric energy meter in real time.
[0101] After the test is completed, the transfer device 2 is replaced with the first clamp 32, which grabs the first object on the test table 9, puts on the electrical tool 53, rotates 90 degrees, and tests again.
[0102] After completing the electrostatic discharge test of the electric energy meter in strict accordance with the national standard, the transfer device 2 is replaced with the second fixture 42 and the tooling power-on device 7 is taken out.
[0103] Transfer device 2 then switches to the first fixture 32 and places the energy meter and first object electrical fixture 53 onto the first object electrical fixture 5. After being positioned by the first positioning device 54, transfer device 2 depresses the stop block 5333 on the first stop assembly 533 and grabs the three-phase energy meter and unloads it onto conveyor line 1, completing the test.
[0104] For the testing process of single-phase electricity meters, in addition to replacing the first object power-on tool 53 with the second object power-on tool 63 in the second object power-on device 6, the corresponding power-on tool is replaced for the terminal or other metering device, and the test can be performed according to the same process as the three-phase electricity meter.
