Description
Technical Field
[0001] This utility model relates to the field of power testing technology, and specifically to a power testing module device. Background Technology
[0002] In the production, repair, and operation of power equipment, performance testing of power modules (such as voltage acquisition modules and power detection modules) is a critical step, requiring parameter testing through interface connection with the testing equipment. Currently, the industry commonly uses a manual plug-and-play method to connect modules to the testing equipment: the tester holds the power module and aligns its interface with the port of the testing equipment for plugging and unplugging. In existing power testing scenarios, some modules and testing equipment may carry residual charges. If the insulation protection is inadequate, direct manual contact during plugging and unplugging can easily lead to electric shock accidents, posing a threat to the personal safety of operators. To reduce the risk of leakage, some scenarios adopt the method of plugging and unplugging after power failure. However, frequent power failures and power-on will cause the internal circuits of the testing equipment and power modules to be subjected to instantaneous voltage surges, accelerating the aging of components such as capacitors and chips, and shortening the service life of the equipment.

[0018] See attached document Figure 1 -Appendix Figure 6The present invention provides a power testing module device, including a testing equipment body 1, a protective shell 2 fixedly provided on the top of the testing equipment body 1, and a testing control mechanism provided inside the protective shell 2; The test control mechanism includes a connecting plate 6. Two first electric push rods 7 are fixedly mounted on the top of the connecting plate 6. A fixing plate 9 is fixedly mounted on the output end of each of the two first electric push rods 7. A connecting shell 10 is fixedly mounted on one side of each of the two fixing plates 9. A support frame 12 is fixedly mounted between the two connecting shells 10. A positioning component and a fixing component are respectively provided on one side of the support frame 12. The positioning component includes two positioning units. Each positioning unit includes a rotating rod 23. The rotating rod 23 is located inside the connecting shell 10 and connected to the side wall of the connecting shell 10 via a bearing. A gear 24 is fixedly sleeved on the outside of the rotating rod 23. Gear plates 26 are provided on both sides of the gear 24. Gear 24 meshes with toothed plate 26. A first positioning plate 27 and a second positioning plate 28 are fixedly provided on one side of the two toothed plates 26 respectively. Multiple sliding columns 29 are connected to one side of the first positioning plate 27 and the second positioning plate 28 through bearings. A second electric push rod 11 is fixedly provided on one side of the connecting shell 10. The output end of the second electric push rod 11 is fixedly connected to the first positioning plate 27. Two sliding rods 25 are fixedly provided inside the connecting shell 10. The sliding rods 25 pass through the toothed plate 26 and are slidably connected to the toothed plate 26. A second sliding groove 31 is provided on both sides of the support frame 12. The first positioning plate 27 and the second positioning plate 28 pass through the second sliding groove 31 and are slidably connected to the second sliding groove 31. In this implementation scheme, the operator places the power module to be tested inside the support frame 12, aligning the module interface downwards with the approximate direction of the port 13. After starting the positioning program, the controller 3 controls the second electric push rod 11 to extend, pushing the toothed plate 26 connected to it to move along the slide rod 25 towards the center of the support frame 12. The toothed plate 26 meshes with the gear 24, causing the gear 24 to rotate around the rotating rod 23, thereby driving the toothed plate 26 on the other side to move in the opposite direction along the slide rod 25 (i.e., move synchronously towards the center of the support frame 12). The toothed plates 26 on both sides respectively drive the first positioning plate 27 and the second positioning plate 28 to move closer together along the second slide groove 31 until the slide column 29 contacts the two sides of the module. To achieve the fixing purpose, the device adopts the following technical solution: The fixing component includes a side shell 17, which is fixedly disposed on one side of the support frame 12. A second motor 18 is fixedly disposed on one side of the side shell 17. A threaded rod 19 is fixedly connected to the output end of the second motor 18. The threaded rod 19 is connected to the side wall of the side shell 17 through a bearing. The threads on both sides of the threaded rod 19 have opposite directions of rotation. Sliding blocks 20 are threadedly fitted on both sides of the threaded rod 19. Two clamping plates 21 are fixedly disposed on one side of each sliding block 20. A pad 22 is fixedly disposed on one side of each clamping plate 21. Two first sliding grooves 30 are opened on one side of the support frame 12. The clamping plates 21 pass through the first sliding grooves 30 and extend into the interior of the support frame 12. The controller 3 automatically starts the second motor 18. The second motor 18 rotates forward to drive the threaded rod 19 to rotate. Since the threads on both sides of the threaded rod 19 have opposite directions of rotation, the sliding blocks 20 on both sides move synchronously towards the center along the threaded rod 19, causing the clamping plates 21 to pass through the first sliding grooves 30. The pad 22 extends into the support frame 12 until it is in close contact with the front and rear sides of the module, thus securing the module firmly and preventing it from shaking during subsequent translation and insertion / removal. To achieve the purpose of movement, the device adopts the following technical solution: The test control mechanism further includes two fixed columns 14, which are fixed inside the protective shell 2. A support shell 5 is fixed at the bottom of the two fixed columns 14. A first motor 8 is fixed on one side of the support shell 5. A lead screw 15 is fixedly connected to the output end of the first motor 8. The lead screw 15 is connected to the side wall of the support shell 5 through a bearing. A slider 16 is threaded on the outside of the lead screw 15. The slider 16 is fixedly connected to the connecting plate 6. Multiple ports 13 are installed on the top of the main body 1 of the test equipment. The first motor 8 starts, driving the lead screw 15 to rotate forward. The slider 16 slides along the lead screw 15 into the protective housing 2. Through the connecting plate 6, it drives the fixing plate 9, the connecting housing 10, and the support frame 12 to move horizontally as a whole. When the slider 16 moves to the preset position (directly above the port 13 to be docked), the first motor 8 stops. At this time, the module interface and the port 13 are in a coaxial position in the vertical direction. After the alignment is completed, the first electric push rod 7 starts and extends downward, pushing the fixing plate 9, the connecting housing 10, and the support frame 12 to move downward as a whole, so that the module interface is accurately inserted into the port 13. To facilitate viewing, the device employs the following technical solution: a viewing window 4 is provided on one side of the protective housing 2, which allows for easy viewing of the insertion and removal status; To achieve the control objective, the device employs the following technical solution: a controller 3 is installed on one side of the protective housing 2, and the controller 3 is a Siemens S7-200 SMART series PLC (model: SR20).
[0019] The usage process of this utility model is as follows: Module Placement and Positioning: By setting preset parameters using controller 3, the operator places the power module to be tested inside the support frame 12, aligning the module interface downwards with the approximate direction of port 13. After starting the positioning program, controller 3 controls the second electric push rod 11 to extend, pushing the toothed plate 26 connected to it to move along slide rod 25 towards the center of support frame 12. The toothed plate 26 meshes with gear 24, causing gear 24 to rotate around rotating rod 23, thereby driving the toothed plate 26 on the other side to move in the opposite direction along slide rod 25 (i.e., move synchronously towards the center of support frame 12). The toothed plates 26 on both sides respectively drive the first positioning plate 27 and the second positioning plate 28 to move closer together along the second slide groove 31 until the slide column 29 contacts both sides of the module. The design function of the sliding column 29 is as follows: Since the sliding column 29 is connected to the positioning plate through the bearing, it can rotate freely. When the module is placed in the support frame, if there is a slight positional deviation, the sliding column 29 will rotate with the slight sliding of the module after contacting the module. This can achieve positioning and guidance, and avoid hard friction scratching the surface of the module. Module clamping and fixing: After positioning is completed, the controller 3 automatically starts the second motor 18. The second motor 18 rotates forward to drive the threaded rod 19 to rotate. Since the threads on both sides of the threaded rod 19 rotate in opposite directions, the sliding blocks 20 on both sides move synchronously towards the center along the threaded rod 19, driving the clamping plate 21 to pass through the first sliding groove 30 and extend into the support frame 12 until the pad 22 is in close contact with the front and rear sides of the module, so as to achieve a stable fixation of the module and prevent the module from shaking during subsequent translation and insertion / removal. Module translation and alignment: After clamping is completed, the first motor 8 starts, driving the lead screw 15 to rotate forward. The slider 16 slides along the lead screw 15 into the protective housing 2. Through the connecting plate 6, the fixing plate 9, the connecting housing 10 and the support frame 12 move horizontally as a whole. When the slider 16 moves to the preset position (directly above the port 13 to be docked), the first motor 8 stops. At this time, the module interface and the port 13 are in a coaxial position in the vertical direction. Automatic insertion and removal test: After alignment, the first electric push rod 7 starts and extends downward, pushing the fixing plate 9, connecting shell 10 and support frame 12 to move down as a whole, so that the module interface is accurately inserted into port 13. After insertion, the internal circuit of the test equipment body 1 starts parameter detection. After the test is completed, the first electric push rod 7 retracts and moves the module upward and away from port 13. Then the first motor 8 reverses and moves the module to the outside of the protective shell 2. The second motor 18 reverses and releases the clamp 21. The second electric push rod 11 retracts and opens the positioning plate. The operator can then take out the module that has been tested and put in the next module to be tested and repeat the above process.
[0020] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
