[0040] It should be noted that each time the lifting motor 37 rotates, the lifting slider 34 maintains the same travel trajectory. Figure 3 As shown in the figure) is the initial position, when the lifting motor 37 is turned on, the lifting slider 34 first slides upward, reaches the top of the first screw rod 33, and then continues to slide down to the inspection position at its bottom. At this time, the lifting motor 37 is turned off to perform the inspection work. After the inspection work is completed, the lifting motor 37 is turned on again. At this time, the lifting slider 34 will move along the first screw rod 33 to its top, and then slide down again (as shown in the figure) Figure 3As shown in the figure, the above is the fixed travel trajectory of the lifting slider 34 when completing an inspection; in addition, each time the friction wheel 451 rotates with the rotating ring 43 by friction, the movable ring 41 rotates 180 degrees along the positioning ring 4, that is, the movable ring 41 will drive the paste storage box 42 to switch positions directly below the telescopic probe 361 and directly below it along the symmetrical side of the lifting sleeve 31.
[0041] Through the arrangement of the above structure, the lifting motor 37 drives the first screw rod 33 to rotate. First, the lifting slider 34 drives the tester 36 to move upward. At this time, the telescopic probe 361 is pulled out of the paste storage box 42, and the conductive paste is adhered to the bottom end of the telescopic probe 361. In the process of the lifting slider 34 moving upward, the paddle 331 will be inserted into the paddle groove 431 in the rotating ring 43 that moves up with the lifting slider 34. At this time, the paddle 331 rotates with the first screw rod 33, thereby driving the rotating ring 43 to rotate around the first screw rod 33. At the same time, the friction force is used to make the rotating ring 43 drive the friction wheel 451 to rotate, and then through the transmission action of the linkage shaft 45 and the drive gear 452, the transmission from The movable gear 46 rotates, and the bending rod 461 is used to pull the movable ring 41 to rotate along the positioning ring 4, thereby driving the paste storage box 42 to leave the bottom of the telescopic probe 361. In the process of moving the paste storage box 42, the rotating centrifugal force can also be used to mix the conductive pastes inside it, avoiding sedimentation or local agglomeration, thereby ensuring the effectiveness of the conductive paste. When the bottom end of the telescopic probe 361 is attached to the surface of the inspection connection gasket of the electric energy metering device, the conductive paste adhered to the bottom end of the telescopic probe 361 will tightly wrap the connection between the telescopic probe 361 and the inspection gasket to form an effective conductive area, thereby avoiding current interruption during the detection process and improving the detection accuracy.
[0042] Reference Figure 1-Figure 5, wherein the driving part includes a second screw rod 5, which is rotatably connected to the guide rail 2, and a translation slider 51 is fixedly connected to the second screw rod 5, and a moving seat 52 is slidably connected to the guide rail 2.

The telescopic end passes through the clamping groove 6 and is fixedly connected to the side wall of the clamping plate 61. There is an air collecting groove 63 inside the fixed seat 21 and the movable seat 52. An inflatable sleeve 64 is fixedly connected to the guide rail 2. The second screw rod 5 passes through the middle of the inflatable sleeve 64. An inflatable pressure plate 641 is slidably connected to the inflatable sleeve 64. A first spring 642 is fixedly connected between the side wall of the inflatable pressure plate 641 and the inner wall of the inflatable sleeve 64.

The other end of the air guide pipe 621 is connected to the inner cavity of the air collecting groove 63.
[0043] Through the arrangement of the above structure, during the sliding process of the translation slider 51, the inflatable pressure plate 641 will be squeezed, so that the inflatable pressure plate 641 slides toward the side of the compressed first spring 642, thereby compressing the gas in the inflatable sleeve 64, so that the gas enters the gas collecting groove 63 along the first gas pipe 65, and then is respectively filled into the four groups of spring telescopic rods 62 by the four air guide pipes 621, so that the telescopic ends of the spring telescopic rods 62 are extended, and the clamping plate 61 is pushed along the clamping groove 6 to approach the side wall of the electric energy metering device, and finally the electric energy metering device is charged by the four groups of clamping plates 61. The electric energy metering device can be clamped and positioned, thereby firstly ensuring the stability of the electric energy metering device in subsequent inspections, and secondly, when the subsequent translation slider 51 moves in the opposite direction along the second screw rod 5, the squeezing of the inflatable pressure plate 641 will be released, and under the rebound action of the first spring 642, the gas filled in the spring telescopic rod 62 will flow back into the inflatable sleeve 64. At this time, the spring telescopic rod 62 will retract, thereby releasing the clamping of the electric energy metering device. In this way, the clamping and loosening of the electric energy metering device can be achieved automatically, which is more convenient for inspection and use, and improves the inspection efficiency.
[0044] Reference Figure 1-Figure 3 、 Figures 6-10The cleaning assembly includes two sets of drive boxes 7, which are fixedly connected to the mounting frame 3 with an electric push rod 71, and the telescopic end of the electric push rod 71 is fixedly connected to the carrying plate 72. The two sets of drive boxes 7 are fixed on the top of the carrying plate 72, and the two sets of drive boxes 7 are rotatably connected to the cleaning rollers 73. The two cleaning rollers 73 pass through the mounting frame 3 from both sides and extend to the bottom of the telescopic probe 361.

A piston plate 761 is slidably connected in the piston chamber 76, and a second spring 762 is fixedly connected between the side wall of the piston plate 761 and the inner wall of the piston chamber 76. The second screw rod 5 in the air pressure chamber 75 is fixedly connected to the magnetic plate 763. The magnetic plate 763 and the piston plate 761 repel each other magnetically. The top of the test platform 1 is fixedly connected to an air storage box 77. The piston chamber 76 and the air storage box 77 are connected through an inflation pipe 771, and a one-way valve is provided in the inflation pipe 771. The top of the air storage box 77 is fixed on both sides and connected to a second air pipe 772. The other end of the second air pipe 772 is connected to the top of the drive box 7. The mounting frame 3 is fixedly connected to an air inlet pipe 78 on both sides. The air inlet pipe 78 is connected to the inner cavity of the piston chamber 76. They are connected, and a one-way valve is provided in the air intake pipe 78; the middle section of the second air pipe 772 is a hose setting, and the second air pipe 772 is fixedly connected to a switching box 8, a switching plate 81 is slidably connected in the switching box 8, a third spring 82 is fixedly connected between the side wall of the switching plate 81 and the inner wall of the switching box 8, and a ventilation groove 811 is provided on the switching plate 81, a contact plate 83 is slidably connected in the mounting frame 3, and the end of the contact plate 83 passes through the mounting frame 3 and is aligned with the end of the switching plate 81.
[0045] It should be noted that the one-way valve in the inflation tube 771 can only allow the gas in the piston chamber 76 to enter the air storage box 77; the one-way valve in the air inlet pipe 78 can only allow the external airflow to be replenished into the piston chamber 76; in addition, an exhaust hole is provided on the side wall of the drive box 7 for discharging the airflow filled in the drive box 7 to ensure that the gas in the drive box 7 continues to flow, thereby driving the drive impeller 74.
[0046] By setting the above structure, during the rotation of the second screw rod 5, the repulsive effect between the magnetic plate 763 and the piston plate 761 will cause the piston plate 761 to slide toward the side of the compressed second spring 762, thereby compressing the gas in the piston chamber 76 and opening the one-way valve in the inflation pipe 771, so that the compressed gas in the piston chamber 76 is filled into the air storage box 77. When the magnetic plate 763 and the piston plate 761 are separated from the repulsive area, the second spring 762 will rebound and pull the piston plate 761 to return to its original position, thereby generating a suction effect in the piston chamber 76, thereby opening the one-way valve in the intake pipe 78, so that the external air flow is replenished into the piston chamber 76, and so on and so forth, which can continuously increase the air volume in the air storage box 77. When the fixing seat 21 moves toward the mounting bracket 3 in the final stage, the end of the spring telescopic rod 62 will squeeze the contact plate 83, and then the two ends of the contact plate 83 will squeeze the switching plate 81, so that the switching plate 81 moves toward the side of the compressed third spring 82, and finally the ventilation groove 811 and the second air pipe 772 are in a connected state. At this time, the high-pressure airflow in the air storage box 77 will instantly flow into the drive box 7 along the second air pipe 772, thereby driving the driving impeller 74 to rotate with the cleaning roller 73, and then frictionally cleaning the surface of the inspection connection gasket of the electric energy metering device, effectively avoiding the formation of an oxide layer on the gasket surface, ensuring the cleanliness of the gasket surface, thereby improving the connection effect and ensuring the inspection accuracy.

During the sliding process of the above-mentioned translation slider 51, the inflatable pressure plate 641 will be squeezed, so that the inflatable pressure plate 641 slides toward the side of the compressed first spring 642, thereby compressing the gas in the inflatable sleeve 64, so that the gas enters the gas collecting groove 63 along the first gas pipe 65, and then is respectively filled into the four groups of spring telescopic rods 62 by the four air guide pipes 621, so that the telescopic ends of the spring telescopic rods 62 are The four sets of clamping plates 61 are used to clamp and position the electric energy metering device, thereby firstly ensuring the stability of the electric energy metering device in subsequent inspections, and secondly, when the translation slider 51 moves in the opposite direction along the second screw rod 5, the squeezing of the inflatable pressure plate 641 will be released. Under the rebound action of the first spring 642, the gas filled in the spring telescopic rod 62 will flow back into the inflatable sleeve 64. At this time, the spring telescopic rod 62 will retract, thereby releasing the clamping of the electric energy metering device. In this way, the clamping and loosening of the electric energy metering device can be realized automatically, which is more convenient for inspection and use, and improves the inspection efficiency.
[0054] When the inspection connection gasket on the electric energy metering device moves to just below the telescopic probe 361, the translation motor 53 stops working, and at this time the two sets of cleaning rollers 73 are just plugged into the surface of the inspection connection gasket on the electric energy metering device. During the rotation of the second screw rod 5, the repulsive effect between the magnetic plate 763 and the piston plate 761 will cause the piston plate 761 to slide toward the side of the compressed second spring 762, thereby compressing the gas in the piston chamber 76 and opening the one-way valve in the inflation pipe 771, so that the compressed gas in the piston chamber 76 is filled into the air storage box 77. When the magnetic plate 763 and the piston plate 761 are separated from the repulsive area, the second spring 762 will rebound and pull the piston plate 761 to reset, thereby generating a suction effect in the piston chamber 76, thereby opening the one-way valve in the intake pipe 78, so that The external air flow is replenished into the piston chamber 76, and this reciprocating process can continuously increase the air pressure in the air storage box 77. When the fixing seat 21 moves toward the mounting bracket 3 in the final stage, the end of the spring telescopic rod 62 will squeeze the contact plate 83, and then the two ends of the contact plate 83 will squeeze the switching plate 81, so that the switching plate 81 moves toward the side of the compressed third spring 82, and finally the ventilation groove 811 and the second air pipe 772 are in a connected state. At this time, the high-pressure air flow in the air storage box 77 will instantly flow into the drive box 7 along the second air pipe 772, thereby driving the driving impeller 74 to rotate with the cleaning roller 73, and then frictionally cleaning the surface of the inspection connection gasket of the electric energy metering device, effectively avoiding the formation of an oxide layer on the gasket surface, ensuring the cleanliness of the gasket surface, thereby improving the connection effect and ensuring the inspection accuracy.
[0055] Then the lifting motor 37 drives the first screw rod 33 to rotate, and at the same time the electric push rod 71 extends to push the carrier plate 72 to move, so that the drive box 7 and the cleaning roller 73 are away from the electric energy metering device, so that the telescopic probe 361 can move down and contact the inspection connection gasket of the electric energy metering device. First, the lifting slider 34 drives the tester 36 to move upward. At this time, the telescopic probe 361 is pulled out of the paste storage box 42, and the conductive paste is adhered to the bottom end of the telescopic probe 361. In the process of the lifting slider 34 moving upward, the paddle 331 will be inserted into the paddle slot 431 in the rotating ring 43 that moves up with the lifting slider 34. At this time, the paddle 331 rotates with the first screw rod 33 The rotating ring 43 is driven to rotate around the first screw rod 33, and the friction force is used to make the rotating ring 43 drive the friction wheel 451 to rotate, and then the driven gear 46 is rotated through the transmission action of the linkage shaft 45 and the driving gear 452. At the same time, the movable ring 41 is pulled to rotate along the positioning ring 4 by the bending rod 461, so as to drive the paste box 42 away from the bottom of the telescopic probe 361. In the process of moving the paste box 42, the centrifugal force of rotation can also be used to mix the conductive pastes inside it, avoiding sedimentation or local agglomeration, thereby ensuring the use effect of the conductive paste. When the rod 33 moves downward, and the pulling groove 431 is separated from the pulling piece 331, the opening of the movable ring 41 coincides with the opening of the positioning ring 4, thereby achieving the avoidance of the paste storage box 42 and ensuring the smooth operation of the device. At this time, the lifting slider 34 carries the tester 36 downward through the above-mentioned open position until the bottom end of the telescopic probe rod 361 is in contact with the surface of the test connection gasket of the electric energy metering device. At this time, the conductive paste adhered to the bottom end of the telescopic probe rod 361 will tightly wrap the connection between the telescopic probe rod 361 and the test gasket, forming an effective conductive area, avoiding the occurrence of current interruption during the detection process, and improving the detection accuracy. Finally, the tester 36 can be turned on to test the electric energy metering device. Carry out inspection work; after the inspection is completed, the lifting slider 34 moves with the tester 36 to the first screw rod 33, and then moves down to the initial position. As mentioned above, during this process, it will continue to drive the movable ring 41 to rotate, so that the paste storage box 42 returns to the lower part of the tester 36, and finally the telescopic probe 361 is inserted into the conductive paste in the paste storage box 42, so as to ensure the subsequent connection and conductive effect of the telescopic probe 361. At the same time, the connecting conductive end of the telescopic probe 361 can be protected when not in use to avoid oxidation or rust of the connecting conductive end of the telescopic probe 361, thereby effectively improving the use effect and durability of the telescopic probe 361.
