Description

Technical Field

[0001] The invention belongs to the field of testing instruments for measuring the time integration of power or current, and in particular relates to an electric energy meter carrier plug-in testing device and an electric energy meter sorting line. Background Art

[0003] When testing old energy meters, relevant documents and standards must be strictly followed. The most critical part is to perform carrier communication test on the carrier module of the old energy meter. Currently, staff need to manually test the old energy meter. The test process includes the following steps: Step S1: A staff member opens a protective cover on the electric energy meter for protecting a carrier module; Step S2: The staff inserts the carrier module into the carrier module compartment of the electric energy meter; Step S3: The staff crimps the power supply terminal and the upper power terminal of the electric energy meter together, so that the power supply terminal can supply power to the electric energy meter; Step S4, power on the electric energy meter, and perform a carrier communication test on the electric energy meter through a carrier copy controller; Step S5, power off the electric energy meter, unplug the carrier module from the carrier module compartment, and record the test results.

[0004] In the process of manual inspection of electric energy meters, since the carrier module needs to be repeatedly plugged and unplugged, and in each process of plugging and unplugging the carrier module, the staff cannot ensure that the carrier module is completely aligned with the carrier module compartment, so there is a situation where the carrier module is not plugged in properly. In this case, the staff will misjudge a good electric energy meter as a bad electric energy meter, affecting the accuracy of the measurement results; at the same time, since the staff cannot plug and unplug the carrier module according to the plug-in and unplug direction of the carrier module every time, the phenomenon of oblique plugging or oblique unplugging will often occur, and each oblique plugging or oblique unplugging will damage the carrier module, resulting in a shorter life of the carrier module. Using manual inspection to detect electric energy meters wastes manpower, and when testing electric energy meters, since the electric energy meters need to be powered on, there is a safety hazard of electric shock to the staff.

[0033] In order to solve the problems in the background technology, the core inventive concept of the present invention is: using a conveying system, a cover opening mechanism, a plug-in mechanism, a communication test system and a PLC automatic control system to simulate the process of manual detection of the electric energy meter, so that the electric energy meter carrier plug-in test device can detect the electric energy meter in an unmanned environment, saving manpower and eliminating the safety hazard of electric shock to the staff. At the same time, it can also reduce the oblique insertion and withdrawal caused by human factors and improve the life of the plug-in module.

[0034] The present invention is further described in detail below in conjunction with embodiments.

[0035] Specific embodiment 1 of the electric energy meter carrier plug-in test device provided by the present invention: like Figures 1 to 4 As shown, as a first type of basic specific implementation, the electric energy meter carrier plug-in test device includes a conveying system 3 for conveying the electric energy meter, a cover opening mechanism 2 for opening and closing the protective cover of the electric energy meter, a plug-in mechanism 1 for inserting the carrier module compartment of the electric energy meter, a communication test system 5 for performing a carrier communication test on the electric energy meter, and a PLC (Programmable Logic Controller) automatic control system 4 for controlling the operation of the electric energy meter carrier plug-in test device; The conveying system 3 includes a tray 32 and a conveyor belt 31 for conveying the tray 32. The tray 32 is provided with an installation slot for installing the electric energy meter. The tray 32 has a preparation position for making the electric energy meter in the installation slot face the plug-in mechanism 1. The cover opening mechanism 2 has a cover opening station for placing the protective cover in an open state; The plug-in mechanism 1 includes a plug-in module for inserting into the carrier module compartment and a plug-in drive structure for driving the plug-in module to approach or move away from the carrier module compartment. The plug-in module has a plug-in station for being in a plug-in state with the carrier module compartment and a separation station for being in a separation state with the carrier module compartment. When the plug-in module is in the plug-in position, the cover opening mechanism 2 is in the cover opening position; The communication test system 5 comprises a power supply terminal for supplying power to the electric energy meter and a carrier copy controller 52 for performing a carrier communication test on the electric energy meter, the power supply terminal having a power supply station for crimping with the upper power terminal of the electric energy meter; When the plug-in module is in the plug-in position and the power supply terminal is in the power supply position, the PLC automatic control system 4 is used to control the carrier copy controller 52 to perform a carrier communication test on the electric energy meter and record the test result.

[0036] Preferably, in the specific embodiment of the improvement of Class 1-1, as Figure 2 As shown, the electric energy meter carrier plug-in test device includes a frame, and the plug-in drive structure includes a plug-in cylinder 16. The output end of the plug-in cylinder 16 is connected to a sliding member 14 for slidingly cooperating with the frame guide. One of the sliding member 14 and the frame is provided with a slide rail 15, and the other is provided with a slide groove matching the slide rail 15. The plug-in module is fixed on the sliding member 14. Under the guidance cooperation between the sliding member 14 and the frame, the plug-in module can be better inserted into the carrier module compartment.

[0037] In the specific implementation of the improvement of category 1-2, the output end of the plug-in cylinder 16 is directly fixedly connected to the plug-in module.

[0038] Of course, the plug-in drive structure can also be replaced with an oil cylinder, an electric cylinder or other direct-acting drive mechanism. The present invention does not limit the specific structure of the plug-in drive structure, as long as the plug-in drive structure can drive the plug-in module to move linearly and the plug-in module has a plug-in station and a separation station.

[0039] It should be noted that, in the present invention, Figures 1 to 4 As shown, the conveying direction of the conveyor belt 31 is defined as the front-to-back direction. In the specific implementation of the 1-3 types of improvements, when the electric energy meter is placed on the tray 32, since the opening of the carrier module compartment faces upward and the power terminal is located on the left or right side of the electric energy meter, the plug-in module moves in the up and down direction and the power supply terminal moves in the left and right direction.

[0040] In the specific implementation methods of the improvements of categories 1 to 4, the plug-in module can also move in the left and right directions, and the power supply terminals can move in the up and down directions. At this time, when the electric energy meter is placed on the tray 32, the opening of the carrier module compartment needs to face left or right, and the upper power terminal needs to be located on the upper side of the electric energy meter.

[0041] In the present invention, the tray 32 may be provided with only one mounting groove, or may be provided with two or more mounting grooves.

[0042] Preferably, in the specific implementation methods of the improvements of categories 1 to 5, two groups of left and right installation slots are provided on the tray 32, and all the installation slots are arranged in a 2×n matrix, n≥1. At this time, all the electric energy meters can be tested at the same time, and the number of tested electric energy meters is the largest, thereby effectively improving the test efficiency.

[0043] In the specific implementation manner of the improvements of categories 1 to 6, two groups of left and right mounting grooves are provided on the tray 32, with two mounting grooves on the left side and one mounting groove on the right side.

[0044] In the present invention, an electric energy meter carrier plug-in test device is used to replace manual labor to complete the test process of the electric energy meter. When in use, the PLC automatic control system 4 can automatically control the electric energy meter carrier plug-in test device to complete the test work without manual participation, thereby saving labor and eliminating the safety hazard of electric shock to workers. At the same time, it can also reduce oblique insertion and oblique withdrawal caused by human factors and improve the life of the plug-in module.

[0045] When actually testing the old electric energy meter, the PLC control system can control the electric energy meter carrier plug-in test device to run according to the following steps: Step S1, moving the tray 32 to the preparation position, at which time the plug-in module is in the separation position; Step S2, switching the cover opening mechanism 2 to the cover opening station; Step S3, switching the plug-in module to the plug-in position, and placing the power supply terminal at the power supply position; Step S4, using the carrier copy controller 52 to perform a carrier communication test on the electric energy meter, and record the test results; Step S5: switch the plug-in module to the separation position, and separate the power supply terminal from the power supply position.

[0046] Since the old electricity meter has been used for a period of time, the shell of the old electricity meter will be deformed to varying degrees compared to the new electricity meter. Therefore, the entrance of the carrier module compartment will also be deformed to varying degrees. When the plug-in module is an existing carrier module, the carrier module is prone to friction with the carrier module compartment, resulting in a shorter life of the carrier module.

[0047] In order to overcome the above problems, the present invention makes the following improvements to the plug-in module: In the specific implementation of the 2-1 type improvement, the plug-in module is composed of a contour module 11, and the shell of the contour module 11 is made of self-lubricating material, thereby reducing the friction between the plug-in module and the carrier module compartment and improving the service life of the plug-in module.

[0048] In the specific implementation of the 2-2 type improvement, the plug-in module is composed of a contour module 11, and a self-lubricating coating is provided on the outer surface of the contour module 11, so as to reduce the friction between the plug-in module and the carrier module compartment and improve the service life of the plug-in module.

[0049] In the improved specific implementation of category 2-1 and the improved specific implementation of category 2-2, the profiling module 11 has the same shape as the carrier module, or the profiling module 11 has a similar shape to the carrier module.

[0050] Preferably, the profiling module 11 is similar in shape to the carrier module, and the difference in shape between the profiling module 11 and the carrier module is that the chamfer size of the profiling module 11 is larger than the chamfer size of the carrier module, so that the profiling module 11 can be better inserted into the carrier module compartment.

[0051] Of course, in the specific implementation of the third type of improvement, the plug-in module can also be an existing carrier module. Similar to the manual testing of an old electric energy meter, after the carrier module is damaged, the staff only needs to replace it with a new carrier module.

[0052] In order to better insert the plug-in module into the carrier module compartment, the present invention makes the following improvements to the plug-in mechanism 1: In the specific implementation of the fourth category of improvements, an elastic buffer 13 is provided on the side of the plug-in module away from the carrier module compartment. The elastic buffer 13 is used to elastically deform when the plug-in module and the carrier module compartment are obliquely inserted, so as to adjust the posture of the plug-in module and avoid jamming between the plug-in module and the carrier module compartment.

[0053] exist Figure 2 In the embodiment, the elastic buffer 13 has a specific structure of two connecting plates connected by four bolts, one of which is fixedly connected to the bolts, and the other connecting plate is provided with a through hole for the bolts to pass through, and each bolt is provided with a spring, which is squeezed between the two connecting plates. Among them, the connecting plate used for fixed connection with the profiling module 11 constitutes the profiling module fixing plate 12.

[0054] Of course, the elastic buffer 13 may also be other existing elastic buffers 13 , as long as the elastic buffer 13 can apply elastic forces of different magnitudes to different positions on the plug-in module, thereby adjusting the position of the plug-in module.

[0055] In the improved specific implementation manner of category 4-1, based on the specific implementation manner of category 1-1, the elastic buffer 13 is installed on the sliding member 14, and the plug-in module is installed on the elastic buffer 13.

[0056] In the improved specific implementation of category 4-2, based on the specific implementation of category 1-2, the output end of the plug-in cylinder 16 is fixedly connected to one side of the elastic buffer 13, and the other side of the elastic buffer 13 is fixedly connected to the plug-in module.

[0057] In order to facilitate opening the protective cover, the following improvements are made to the cover opening mechanism 2 in the present invention: In the specific implementation of the 5th category of improvement, the cover opening mechanism 2 includes a cover-opening assembly for opening the protective cover, the cover-opening assembly includes a rotating arm 22 and a negative pressure suction cup 21 connected to one end of the rotating arm 22 and used for adsorbing the protective cover, the negative pressure suction cup 21 is provided with a vacuum generator, and the end of the rotating arm 22 away from the negative pressure suction cup 21 is fixedly connected with a rotating shaft 24, and the rotating shaft 24 is provided with a rotating shaft driving structure for rotating the rotating shaft 24 along its own axis, and the structure is simple.

[0058] The shaft driving structure can be a rotating cylinder. When the number of lid-opening assemblies is at least two (for example, two, three or more), the shaft driving structure can include a lid-opening cylinder 23. The lid-opening cylinder 23 outputs a direct-acting action, and the output end of the lid-opening cylinder 23 simultaneously controls the rotation of all shafts 24 through a gear transmission mechanism, thereby opening at least two protective covers at one time, and the structure is simple.

[0059] In the sixth improved specific implementation, the cover opening mechanism 2 includes a finger cylinder for clamping the protective cover and a rotary cylinder for driving the finger cylinder to rotate.

[0060] In the present invention, the specific structure of the cover opening mechanism 2 is not limited, as long as the cover opening mechanism 2 can open the protective cover.

[0061] In order to better position the tray 32, the present invention makes the following improvements to the conveying system 3: In the specific implementation of the 7th category improvement, the conveying system 3 also includes a stopping mechanism 33 for stopping the pallet 32, the stopping mechanism 33 includes a stopping member, the stopping member has a stopping position for stopping the pallet 32 ​​and an avoiding position for avoiding the pallet 32, the stopping mechanism 33 also includes a stopping drive structure for switching the stopping member between the stopping position and the avoiding position, the stopping drive structure can be a direct-acting cylinder or a rotary cylinder, and of course can also be other direct-acting or rotary power sources.

[0062] By using the stopping member to stop the tray 32 , the tray 32 can be stopped at a certain position, so that the tray 32 can reach the preparation station better.

[0063] In the specific implementation manner of the improvement of category 7-1, the stopping member stops the tray 32 at the preparation station, the conveyor belt 31 stops moving, and the electric energy meter is started to be tested.

[0064] In the specific implementation of the 7-2 type improvement, the conveying system 3 also includes a lifting mechanism 34 for lifting the pallet 32 ​​stopped by the blocking member upward to detach from the conveyor belt 31, the lifting mechanism 34 includes a lifting member for contacting the pallet 32 ​​and a lifting drive structure for driving the pallet 32 ​​to rise and fall, one of the lifting member and the pallet 32 ​​is provided with a positioning pin, and the other is provided with a positioning hole matching the positioning pin, and when the pallet 32 ​​is in the preparation position, the pallet 32 ​​is not in contact with the conveyor belt 31.

[0065] On the one hand, the positioning pin cooperates with the positioning hole to better locate the position of the tray 32, and thus better locate the position of the carrier module compartment of the electric energy meter; on the other hand, when one tray 32 is in the preparation position, the conveyor belt 31 is still moving, which does not affect the continued movement of other trays 32 on the conveyor belt 31, which is beneficial to improving the detection efficiency.

[0066] In the specific implementation of the 8th category improvement, the electric energy meter carrier plug-in test device also includes a position sensor for detecting the position of the tray 32. The position sensor can be a commonly used position sensor such as a photoelectric sensor or a visual sensor. After the position sensor detects that the tray 32 has arrived at the specified position, the conveyor belt 31 stops moving, so that the tray 32 arrives at the preparation station.

[0067] In order to conveniently crimp and power on the electric energy meter, the present invention makes the following improvements to the communication test system 5: like Figures 1 to 4 As shown, in the specific implementation of the 9th category improvement, the power supply terminal is configured with a power supply drive structure for driving the power supply terminal close to or away from the electric energy meter. The power supply drive structure can be a direct-acting power source such as a direct-acting cylinder, which has a simple structure. It can also include a rotational power source and a transmission mechanism that converts the rotational motion output by the rotational power source into a direct-acting motion.

[0068] Specifically, in Figures 1 to 4 In the specific implementation manner of category 9-1, multiple power supply terminals are located on the same crimping power supply seat 51, and the direct-acting cylinder simultaneously pushes the multiple power supply terminals on the same crimping power supply seat 51 to move.

[0069] In the specific implementation manner of category 9-2, each power supply terminal is equipped with a direct-acting cylinder.

[0070] It should be noted that the power supply terminal can be configured with a power source 53, and the power source 53 supplies power to the electric energy meter through the power supply terminal; or, the power supply terminal is electrically connected to the power grid through a wire. The communication test system 5 can also include a serial port server 54, which can provide stable communication between various devices inside the electric energy meter carrier plug-in test device. The communication test system 5 also includes an industrial computer 55, which processes the data measured by the carrier copy controller 52 and transmits the processed data to a remote host computer or a field display.

[0071] Specific embodiment 2 of the electric energy meter carrier plug-in test device provided by the present invention: The object of the present invention is to provide an electric energy meter carrier plug-in test device with a plug-in module and a carrier module compartment having different plug-in modes.

[0072] Reference Figures 1 to 5 As shown, the main difference between this embodiment and specific embodiment 1 is that in specific embodiment 1, the plug-in module moves to achieve the plug-in connection between the plug-in module and the carrier module compartment, while in this embodiment, the carrier module compartment moves to achieve the plug-in connection between the plug-in module and the carrier module compartment.

[0073] Compared with the first basic specific implementation, the main difference between the tenth basic specific implementation and the first basic specific implementation is that: in the tenth basic specific implementation, the plug-in mechanism 1 includes a plug-in module for inserting into the carrier module compartment, the conveying system 3 also includes a direct-acting drive module for driving the tray 32 to approach or move away from the plug-in module, and the tray 32 also has a test station for putting the plug-in module and the carrier module in a plug-in state; When the tray 32 is in the testing position, the cover opening mechanism 2 is in the cover opening position; When the tray 32 is at the testing position and the power supply terminal 6 is at the power supply position, the PLC automatic control system 4 is used to control the carrier copy controller 52 to perform a carrier communication test on the electric energy meter and record the test result.

[0074] When actually testing the old electric energy meter, the PLC control system can control the electric energy meter carrier plug-in test device to run according to the following steps: Step S1, moving the tray 32 to the preparation station; Step S2, switching the cover opening mechanism 2 to the cover opening station; Step S3, moving the tray 32 to the testing station, and placing the power supply terminal 6 at the power supply station; Step S4, using the carrier copy controller 52 to perform a carrier communication test on the electric energy meter, and record the test results; Step S5: Move the tray 32 to the preparation station, and remove the power supply terminal 6 from the power supply station.

[0075] To simplify the structure, Figure 5 As shown, in the specific implementation manner of the 11th type of improvement, the communication test system 5 includes a power supply terminal 6 and a guide cylinder 9, the guide cylinder 9 cooperates with the frame to guide movement along the left and right directions, a compression spring 8 is mounted on the guide cylinder 9, the compression spring 8 is compressed between the power supply terminal 6 and the frame, and a through hole is opened in the guide cylinder 9, and the wire 7 passes through the through hole to be electrically connected to the power supply terminal 6.

[0076] The power supply terminal 6 is provided with a guiding bevel 61 for guiding and cooperating with the power-on terminal. When the tray 32 is switched from the preparation station to the test station, the power-on terminal contacts the guiding bevel 61 and drives the power supply terminal 6 to compress the compression spring 8. When the tray 32 is located at the test station, the power-on terminal is separated from the guiding bevel 61, and the power supply terminal 6 is pressed tightly by the compression spring 8. At this time, the power supply terminal 6 is in the power supply station; when the tray 32 is switched from the test station to the preparation station, the compression spring 8 is reset, thereby causing the power supply terminal 6 to leave the power supply station.

[0077] Of course, in the twelfth specific implementation manner, the power supply terminal 6 may also be configured with a direct-acting cylinder for moving the power supply terminal 6 left and right.

[0078] Compared with the twelfth specific implementation, in the eleventh specific implementation, there is no need to additionally provide a power source such as a direct-acting cylinder, and the structure is simple.

[0079] In the present invention, the crimping method of the power supply terminal 6 and the power-on terminal is not limited, as long as the power supply terminal 6 can be crimped with the power-on terminal when the tray 32 is in the testing station.

[0080] It should be noted that the electric energy meter carrier plug-in test device in the present invention can also be used to detect brand new electric energy meters.

[0082] An upper table robotic arm robot for placing undetected electric energy meters on the tray 32 is provided upstream of the electric energy meter carrier plug-in test device, and a lower table robotic arm robot for moving detected electric energy meters out of the tray 32 is provided downstream of the electric energy meter detection device, and the lower table robotic arm robot is used to move the available electric energy meters and the unavailable electric energy meters to different areas according to the test results of the electric energy meter carrier plug-in test device.

[0083] In the present invention, the electric energy meter sorting line is used to replace manual labor to complete the sorting process of the electric energy meters. When in use, the upper table mechanical arm robot can place the old electric energy meter on the tray 32, the PLC automatic control system 4 can automatically control the electric energy meter carrier plug-in test device to complete the test work, and the lower table mechanical arm robot can separate the usable electric energy meters from the unusable electric energy meters without manual participation, thereby saving labor and eliminating the safety hazard of electric shock to the staff. At the same time, it can also reduce the oblique insertion and oblique withdrawal caused by human factors, and improve the life of the plug-in module.

[0084] It should be noted that the present invention only classifies the specific embodiments according to specific structures, which does not mean that other categories do not contain this specific structure. For example, the structure of the first category of specific embodiments may be the same as that of the second or third category of specific embodiments.
