Technical Field

[0001] This invention relates to the field of electricity meter testing technology, and in particular to an electricity meter testing device and its usage method. Background Technology

[0002] In electricity meter testing systems, visual inspection of the electricity meter is a critical step, as it allows for the early detection of defects in the meter's casing and LCD screen area. For example... Figure 1 As shown, the areas of the electricity meter 100 that need to be visually inspected are the upper surface 101, the front surface 102, the left side surface 103, the rear surface 104, and the right side surface 105. The LCD screen 1011 is located on the upper surface 101. Currently, the visual inspection of electricity meters is usually done by manual visual inspection. However, manual inspection requires a lot of manpower and there is a risk of missed inspections due to fatigue, which cannot meet the requirements of mass production of electricity meters. Summary of the Invention

[0003] The technical problem to be solved by this invention is that the current method of visual inspection of electricity meters is not feasible for mass production of electricity meters.

[0004] To address the aforementioned technical problems, the present invention aims to provide an electricity meter testing device, comprising a support platform, on which a first detection position and a second detection position are arranged at intervals from left to right. An electricity meter is placed on the first detection position. A support frame is fixed on the support platform, and a first camera and a second camera are fixed on the support frame at intervals from front to back. The second camera is tilted towards the left rear of the first detection position to capture images of the rear, left, and top sides of the electricity meter located at the first detection position. The support platform is provided with a transfer device for transferring the electricity meter from the first detection position to the second detection position. The first camera is tilted towards the right front of the second detection position to capture images of the front, right, and top sides of the electricity meter moved to the second detection position.

[0005] As a preferred embodiment, the transfer device includes a first clamping plate and a second clamping plate arranged in parallel at intervals, the interval between the first clamping plate and the second clamping plate forming a clamping space, and the first detection position and the second detection position are both located in the clamping space;

[0006] Both the first clamping plate and the second clamping plate are fixed with baffles that extend away from the clamping space in the front-back direction. Each baffle is connected to a vertically arranged guide pin at the end away from the clamping space. Each support platform is provided with a straight-edged elliptical annular guide groove that extends in the left-right direction at the position opposite to each guide pin.

[0007] The transfer device further includes a driving mechanism, which drives each of the guide pins to move along the corresponding guide groove. When each of the guide pins moves along the corresponding straight portion of the guide groove, the first clamping plate and the second clamping plate clamp the energy meter and move the energy meter from the first detection position to the second detection position.

[0008] As a preferred embodiment, the electricity meter testing device includes at least two telescopic rods arranged parallel to each other on the left and right, one end of each telescopic rod is connected to the first clamping plate, and the other end of each telescopic rod is connected to the second clamping plate;

[0009] One of the two baffles is provided with a limiting groove arranged in the front-to-back direction. The driving mechanism includes a motor fixedly connected to the support platform and a connecting member connected to the output shaft of the motor to prevent rotation. A stop pin is fixed at the end of the connecting member away from the motor, and the stop pin is inserted into the limiting groove.

[0010] The guide pin is made of magnetic material, and a magnet is fixed on the outer side of the arc portion of each guide groove to apply magnetic force to the guide pin so that the guide pin moves along the arc portion of the corresponding guide groove.

[0011] As a preferred embodiment, each of the telescopic rods includes a sleeve, a first L-shaped rod, and a second L-shaped rod. The sleeve extends in the front-back direction and is arranged above the support platform. The first end of the first L-shaped rod and the first end of the second L-shaped rod are respectively inserted into the two ends of the sleeve. The second end of the first L-shaped rod and the second end of the second L-shaped rod are respectively fixedly connected to the first clamping plate and the second clamping plate.

[0012] As a preferred embodiment, the electricity meter testing equipment includes a first conveyor belt for transporting the tested electricity meters. The first end of the first conveyor belt is located to the left of the second testing position. The right half of the first clamping plate and the right half of the second clamping plate clamp the electricity meter and move the electricity meter from the first testing position to the second testing position. When each of the guide pins is located at the left arc portion of the corresponding guide groove, the left half of the first clamping plate and the left half of the second clamping plate both move to above the first end of the first conveyor belt.

[0013] As a preferred embodiment, the lower ends of the first clamping plate and the lower ends of the second clamping plate are each connected to a plurality of steel balls at intervals on the left and right, and the ball end of each steel ball abuts against the upper end of the support platform.

[0014] As a preferred embodiment, a telescopic drive device is fixed on the support platform. The telescopic end of the telescopic drive device is connected to a meter holder for testing the connection of the electricity meter. The pins of the meter holder are arranged one-to-one with the wiring holes of the electricity meter. When the transfer device clamps the electricity meter, the telescopic drive device extends to insert each of the pins into the corresponding wiring holes.

[0015] As a preferred embodiment, the electricity meter testing equipment includes a second conveyor belt for conveying the electricity meter to be tested. The right side of the support platform has a notch with an opening facing to the right. The end of the second conveyor belt is located in the notch, and the portion of the second conveyor belt located in the notch forms the first testing position.

[0016] A method of using the above-mentioned electricity meter testing device, characterized by comprising the following steps:

[0017] Step S1: Place the electricity meter in the first detection position;

[0018] Step S2: Take a first picture of the energy meter located at the first detection position using the second camera;

[0019] Step S3: Use the transfer device to move the energy meter from the first detection position to the second detection position;

[0020] Step S4: Use the first camera to take a second picture of the energy meter located at the second detection position.

[0021] As a preferred embodiment, in step S3, after the transfer device clamps the electricity meter and before moving the electricity meter, the telescopic drive device drives the meter holder to move backward, so that each pin is inserted into the corresponding wiring hole. The second camera takes a third picture of the electricity meter after it is connected to the ground. After that, the telescopic drive device drives the meter holder to move backward, so that each pin is dislodged from the corresponding wiring hole.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The electricity meter testing equipment of the present invention includes a support platform with a first detection position and a second detection position arranged at a left-right interval on the support platform. The electricity meter is placed on the first detection position. A support frame is fixed on the support platform, and a first camera and a second camera arranged at a front-back interval are fixed on the support frame.

[0040] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0041] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms; these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0042] like Figures 2 to 15 As shown, a preferred embodiment of the electricity meter testing device of the present invention includes a support platform 1. The support platform 1 has a first detection position and a second detection position arranged at intervals from left to right. An electricity meter 100 is placed on the first detection position. A support frame 2 is fixed on the support platform 1. A first camera 21 and a second camera 22 are fixed on the support frame 2, arranged at intervals from front to back. The second camera 22 is tilted towards the left rear of the first detection position to take pictures of the rear, left, and top sides of the electricity meter 100 located at the first detection position. The support platform 1 is provided with a transfer device for transferring the electricity meter 100 from the first detection position to the second detection position. The first camera 21 is tilted towards the right front of the second detection position to take pictures of the front, right, and top sides of the electricity meter 100 moved to the second detection position. Therefore, by using the first camera 21 and the second camera 22, all areas of the electricity meter 100 that need to be tested can be photographed, realizing the appearance inspection of the electricity meter, avoiding the risk of missed inspections due to fatigue in manual inspection, and meeting the requirements of mass production of electricity meters.

[0043] There are various ways to set up the transfer device, such as setting up a linear module arranged in the left-right direction, with the end of the linear module connected to a clamping mechanism. In this embodiment, the transfer device includes a first clamping plate 31 and a second clamping plate 32 arranged in parallel front-back, with the gap between the first clamping plate 31 and the second clamping plate 32 forming a clamping space. The first detection position and the second detection position are both located in the clamping space. The first clamping plate 31 and the second clamping plate 32 are each fixed with a baffle 33 extending in the front-back direction away from the clamping space. Each baffle 33 is away from the clamping space. Each of the guide pins 34 is connected to a vertically arranged guide pin 34 at one end. The support platform 1 has a straight-edged elliptical annular guide groove 11 extending in the left-right direction at a position opposite to each guide pin 34 vertically. The transfer device also includes a drive mechanism, which drives each guide pin 34 to move along its corresponding guide groove 11. When each guide pin 34 moves along the corresponding straight section of its corresponding guide groove 11, the first clamping plate 31 and the second clamping plate 32 clamp the energy meter 100 and move the energy meter 100 from the first detection position to the second detection position. Specifically, the drive mechanism can be implemented in various ways, such as by setting a rack along the edge of the guide groove on one side wall of the guide groove, connecting the guide pin 34 to a gear meshing with the rack, and providing a rotary motor to drive the guide pin 34 to rotate. The rotary motor drives the guide pin to rotate, which in turn drives the gear to rotate, causing the gear to move along the rack. At this time, the guide pin 34 is rotatably connected to the baffle 33.

[0044] In this embodiment, the electricity meter detection device includes at least two telescopic rods 35 arranged parallel to each other on the left and right. One end of each telescopic rod 35 is connected to the first clamping plate 31, and the other end of each telescopic rod 35 is connected to the second clamping plate 32. One of the two baffles 33 is provided with a limiting groove 331 arranged in the front-back direction. The driving mechanism includes a motor 41 fixedly connected to the support platform 1 and a connector 42 connected to the output shaft of the motor 41 to prevent rotation. A stop pin 43 is fixed at the end of the connector 42 away from the motor 41, and the stop pin 43 is inserted into the limiting groove 331. The guide pin 34 is made of magnetic material, and a magnet 36 is fixed on the outer side of the arc portion of each guide groove 11 for applying magnetic force to the guide pin 34 so that the guide pin 34 moves along the arc portion of the corresponding guide groove 11. Specifically, in this embodiment, the motor 41 is located in front of the guide groove 11 near the rear of the support platform. The connecting member 42 is a rotating wheel, and the lower end of the stop pin 43 is fixed to the edge of the rotating wheel. The rotation of the motor 4 drives the rotating wheel to rotate, and the stop pin 43 drives the baffle 33 to move left and right. The setting of the limiting groove 331 ensures that the stop pin 43 can only apply a left and right force to the baffle 33. The baffle 33 can move up and down relative to the stop pin 43. When the stop pin 43 moves to the lower part of the left arc portion, the magnet 36 located at the upper left of the guide groove 11 applies an upward magnetic attraction force to the stop pin 43, thereby causing the stop pin 43 to move along the left arc portion to the upper left part of the left arc portion, thereby releasing the clamping state of the first clamping plate and the second clamping plate. The setting of the telescopic rod 35 enables the first clamping plate 31 to be linked with the second clamping plate 32. The clamping and moving of the energy meter can be achieved by rotating only one motor 41.

[0045] In this embodiment, each telescopic rod 35 includes a sleeve 351, a first L-shaped rod 352, and a second L-shaped rod 353. The sleeve 351 extends in the front-rear direction and is arranged above the support platform 1. The first end of the first L-shaped rod 352 and the first end of the second L-shaped rod 353 are respectively inserted into the two ends of the sleeve 351. The second end of the first L-shaped rod 352 and the second end of the second L-shaped rod 353 are respectively fixedly connected to the first clamping plate 31 and the second clamping plate 32. Specifically, the telescopic rod 35 is generally gantry-shaped, allowing the energy meter to pass through the gantry opening for easy movement. Further, a compression spring is inserted in the middle of the sleeve 351, and the ends of the first ends of the first L-shaped rod 352 and the second L-shaped rod 353 abut against the two ends of the compression spring.

[0046] Furthermore, the electricity meter testing equipment includes a first conveyor belt 51 for transporting the tested electricity meters 100. The first end of the first conveyor belt 51 is located to the left of the second testing position. The right half of the first clamping plate 31 and the right half of the second clamping plate 32 clamp the electricity meter 100 and move the electricity meter 100 from the first testing position to the second testing position. When each of the guide pins 34 is located at the left arc portion of the corresponding guide groove 11, the left half of the first clamping plate 31 and the left half of the second clamping plate 32 both move above the first end of the first conveyor belt 51. This achieves automatic collection of the tested electricity meters.

[0047] The first clamping plate 31 and the second clamping plate 32 can be connected to the support platform through a guide mechanism. In this embodiment, in order to reduce manufacturing costs, multiple steel balls 37 are connected to the lower ends of the first clamping plate 31 and the second clamping plate 32 at intervals on the left and right. The ball end of each steel ball 37 abuts against the upper end of the support platform 1.

[0048] To test the performance of the electricity meter after it is powered on, it is necessary to test the connection wires. In this embodiment, a telescopic drive device 61 is fixed on the support platform 1. The telescopic end of the telescopic drive device 61 is connected to a meter holder 62 for testing the connection wires of the electricity meter 100. The pins of the meter holder 62 are arranged one-to-one with the wiring holes of the electricity meter 100. When the transfer device clamps the electricity meter 100, the telescopic drive device 61 extends to insert each pin into the corresponding wiring hole. Specifically, as shown... Figure 7 As shown, after the first clamping plate 31 and the second clamping plate 32 clamp the energy meter and before the energy meter moves to the left, the telescopic drive device 61 drives the meter holder to move backward, so that each pin is inserted into the corresponding wiring hole, thereby realizing the detection of the connection wire of the energy meter.

[0049] In this embodiment, the electricity meter can be manually placed in the first detection position. In order to further improve the working efficiency of the electricity meter detection device of the present invention, the electricity meter detection device includes a second conveyor belt 52 for conveying the electricity meter 100 to be tested. The right side of the support platform 1 is provided with a notch with an opening facing the right. The end of the second conveyor belt 52 is located in the notch. The part of the second conveyor belt 52 located in the notch forms the first detection position.

[0050] A method of using the above-mentioned electricity meter testing device, characterized by comprising the following steps:

[0051] Step S1: Place the electricity meter 100 in the first detection position;

[0052] Step S2: Take a first picture of the energy meter 100 located at the first detection position using the second camera 22; taking a picture of the energy meter 100 before the transfer device clamps the energy meter 100 can avoid the clamping part of the transfer device from blocking the energy meter, so that the second camera can take a more complete picture of the energy meter.

[0053] Step S3: Use the transfer device to move the electricity meter 100 from the first detection position to the second detection position;

[0054] Step S4: Take a second picture of the energy meter 100 located at the second detection position using the first camera 21. Further, before the first camera 21 takes a picture of the energy meter 100, the transfer device releases the energy meter 100 to avoid the clamping part of the transfer device blocking the energy meter 100 when the first camera 21 takes a picture of the energy meter 100.

[0055] In step S3, after the transfer device clamps the electricity meter 100 but before moving the electricity meter 100, the telescopic drive device 61 drives the meter holder 62 to move backward, causing each pin to insert into the corresponding wiring hole. The second camera 22 takes a third picture of the electricity meter 100 after it is powered on. After the second camera 22 takes the third picture of the electricity meter 100 after it is powered on, the telescopic drive device 61 drives the meter holder 62 to move backward, causing each pin to disengage from the corresponding wiring hole. The third picture captures an image of the display screen area after the electricity meter is powered on, thereby detecting the internal power-carrying performance of the electricity meter.

[0056] Specifically, the method of using the electricity meter testing device of the present invention is as follows:

[0057] like Figure 5 Before the second conveyor belt 52 transports the energy meter 100 to the first detection position, the guide pin 34 is located at the upper part of the right arc portion of the guide groove 11, and the first clamping plate 31 and the second clamping plate 32 are in a non-clamping state; Figure 6 As shown, after the second conveyor belt 52 transports the energy meter 100 to the first detection position, with the first clamping plate 31 and the second clamping plate 32 in a non-clamping state, the second camera takes a first picture of the energy meter 100, thus capturing the side, left side, and top of the energy meter 100; after the second camera completes the first picture of the energy meter 100, as shown... Figure 7 As shown, the motor 41 rotates, driving the baffle 33 to move to the right. Simultaneously, the magnet 36 located at the lower right of the guide groove 11 at the rear of the support platform 1 attracts the guide pin 34 downwards, causing the guide pin 34 to move to the front straight section of the guide groove 11 at the rear of the support platform 1, thereby switching the first clamping plate 31 and the second clamping plate 32 into a clamping state. Afterwards, the motor 41 stops rotating, as... Figure 8As shown, the retraction drive device 61 drives the meter holder 62 to move backward, so that each of the pins is inserted into the corresponding wiring hole. The second camera 22 takes a third picture of the energized energy meter 100. After the second camera 22 takes a third picture of the energized energy meter 100, as shown... Figure 9 As shown, the telescopic drive device 61 drives the watch holder 62 to move backward, causing each of the pins to disengage from its corresponding wiring hole; after each pin disengages from its corresponding wiring hole, as... Figure 10 As shown, the motor 41 continues to rotate, causing the first clamping plate 31 and the second clamping plate 32 to clamp the energy meter to the second detection position; thereafter, as... Figure 11 As shown, under the action of the magnet 36 on the left side of the guide groove 11, the first clamping plate 31 and the second clamping plate 32 switch to the loosened state; thereafter, as... Figure 12 As shown, the rotation of motor 41 drives the first clamping plate 31 and the second clamping plate 32 to move to the right to the initial position; then, as... Figure 13 As shown, while the right half of the first clamping plate 31 and the right half of the second clamping plate 32 clamp the next energy meter, the left half of the first clamping plate 31 and the left half of the second clamping plate 32 clamp the energy meter located at the second detection position. When the first clamping plate 31 and the second clamping plate 32 move to the left again, as... Figure 14 As shown, the left half of the first clamping plate 31 and the left half of the second clamping plate 32 clamp the energy meter located at the second detection position onto the first conveyor belt 51. After the first clamping plate 31 and the second clamping plate 32 are released again, the first conveyor belt 51 removes the tested energy meter. Therefore, the transfer device can simultaneously perform assembly-line progressive testing and transportation of the second energy meter while testing and transporting the first energy meter, thereby realizing the function of continuous meter testing. Since the testing process of the second energy meter is the same as that of the first energy meter, it will not be described in detail here. Because the present invention uses magnetic force to change the direction of the guide pin, all metal materials are made of 6061A aluminum material to avoid interference of magnetic force on the movement of the mechanism body.

[0058] In summary, the electricity meter testing equipment of the present invention includes a support platform 1, on which a first detection position and a second detection position are arranged at intervals from left to right. An electricity meter 100 is placed on the first detection position. A support frame 2 is fixed on the support platform 1, and a first camera 21 and a second camera 22 are fixed on the support frame 2 at intervals from front to back. The second camera 22 is tilted towards the left rear of the first detection position to take pictures of the rear, left, and top sides of the electricity meter 100 located at the first detection position. The support platform 1 is provided with a transfer device for transferring the electricity meter 100 from the first detection position to the second detection position. The first camera 21 is tilted towards the right front of the second detection position to take pictures of the front, right, and top sides of the electricity meter 100 moved to the second detection position. Therefore, by using the first camera 21 and the second camera 22, all areas of the electricity meter 100 that need to be tested can be photographed, realizing the appearance inspection of the electricity meter, avoiding the risk of missed inspections due to fatigue in manual inspection, and meeting the requirements of mass production of electricity meters. By setting the first and second cameras at different positions and angles, and combining the opening and closing actions of the first and second clamping plates, the first and second cameras can take pictures and compare various surfaces and areas of the electricity meter. Compared with the functions of existing special machines, this method can achieve a more comprehensive inspection of the appearance of the electricity meter, and avoid blind spots in appearance inspection caused by the obstruction of the first and second clamping plates, thus reducing the possibility of missed detections and misjudgments. In addition, by controlling the rotation of the turntable through the motor, the stop pin rotates around the motor shaft. By setting the stop pin in the limiting groove 331, the rotational motion of the motor is converted into the linear motion of the stop plate in the left and right directions, and the stop plate can move up and down. A magnet is added to the arc part of the guide groove 11. Combined with the rotation of the motor 41, the guide pin 34, made of magnetic material, can switch between the two linear parts in the guide groove 11 to complete the clamping and releasing actions of the electricity meter 100. The clamping and positioning and the transportation of the electricity meter are combined into a set of linkage devices.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
