[0002] Existing electricity meters often exhibit issues such as excessively fast readings after production, primarily due to insufficient accuracy of the meter's main board. To address this problem, most electricity meter main board suppliers conduct accuracy tests on the meters before they leave the factory, making adjustments based on the test results.

[0003] The existing Chinese utility model patent with application number CN201821849489.X relates to a tooling for calibrating the accuracy of an electricity meter motherboard, including a base plate, a test seat, a mounting slot, a positioning plate, a slot, a test pin, a positioning pin, a bracket, a crossbeam, and a telescopic cylinder, which can reduce the manual dependence during the accuracy calibration of the electricity meter motherboard and improve the calibration effect and efficiency.

[0004] The above-mentioned device uses a telescopic cylinder to drive a pressure plate to assist in fixing the main board of the electricity meter. However, it is difficult to control the pressure of the telescopic cylinder in actual use. At the same time, it is easy to damage the main board when fixing a main board that is not properly positioned. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a power meter motherboard accuracy calibration device that uses a support device to support the motherboard during testing, facilitates the replacement and fixation of its own components, and increases the stability of the testing equipment. A fixing device secures the motherboard placed on the support device, preventing the motherboard's own shaking during testing from affecting the accuracy of the test data, while also preventing pressure damage to the circuit board during the fixing process. An auxiliary device assists in cleaning the metal contacts, thus improving the device's practicality.

[0006] This utility model discloses a power meter mainboard accuracy calibration device, comprising a support device, a fixing device, and an auxiliary device. The fixing device is mounted on the support device, and the auxiliary device is mounted on the support device. The support device provides support for the mainboard testing and facilitates the replacement and fixing of its own components, increasing the stability of the equipment testing. The fixing device fixes the position of the mainboard placed on the support device, preventing the mainboard's own shaking during the testing process from affecting the accuracy of the test data, and also preventing pressure damage to the circuit board caused by the fixing process. The auxiliary device assists in cleaning the metal contacts, improving the practicality of the device.

[0007] Preferably, the support device includes a frame, a placement slot, a test seat, a side pressure plate, and a limiting groove. Multiple placement slots are provided on the upper surface of the frame, allowing multiple test seats to be placed into them. A side pressure plate is installed at the rear of each placement slot, with a limiting protrusion at the front. A limiting groove is provided on the rear surface of the test seat corresponding to the limiting protrusion on the side pressure plate. The test seat is equipped with a test pin and a positioning pin. The test seat is placed into the placement slot, and its position is fixed by the limiting protrusion on the side pressure plate and the limiting groove on the test seat. Then, the main board is placed on the test pin on the test seat, reducing the impact of vibration on the test seat's own body during testing. Simultaneously, moving the side pressure plate separates the protrusion on the side pressure plate from the limiting groove on the test seat, facilitating quick removal of the test seat from the placement slot for maintenance or replacement, thus improving the practicality and stability of the device.

[0008] Preferably, the fixing device includes a rotating groove, a strip groove, an L-shaped cover plate, cylindrical protrusions, limiting light rods, and magnets. Multiple sets of rotating grooves are provided on the rear part of the upper end face of the frame, located behind multiple sets of placement slots. A set of strip grooves is provided on each of the left and right end faces of the rotating grooves. The lower part of the L-shaped cover plate is located inside the rotating groove, and a set of cylindrical protrusions is provided on each of the left and right end faces of the L-shaped cover plate.

After the circuit board is placed on the test stand, rotate the L-shaped cover so that its upper part covers the circuit board. Then, insert the two sets of limiting light rods on the L-shaped cover into the two sets of circular slots on the front side of the placement slot. With the help of the magnet, the front part of the L-shaped cover is attracted, so that the L-shaped cover applies a certain pressure to the circuit board to ensure that the circuit board contacts can press the test pins on the test stand. After the test is completed, lift the L-shaped cover upward and rotate it so that its upper part rotates to the rear side of the placement slot, making it easier to remove the circuit board. The lifting height and pressing position of the L-shaped cover are limited by the strip groove and cylindrical protrusion, which improves the practicality of the device.

The device is positioned above the testing area. The drive motor is then activated to transmit power to the lead screw, causing it to rotate. The rotating lead screw moves the transverse platform laterally, which in turn moves the fan to different test seats. The fan pressurizes external air and blows it into the testing area, thus assisting in cleaning and cooling the area and reducing the impact of dust and debris on the test data. During continuous testing, the test pins on the test seats may experience localized heat buildup. The cylindrical protrusions provide auxiliary heat dissipation for the test pins, improving the practicality and stability of the device.

[0011] Preferably, it also includes a rubber pull tab, and a rubber pull tab is provided on the rear end face of the side pressure plate; the rubber pull tab provided on the rear end face of the side pressure plate makes it easy for the operator to pry open the side pressure plate to install and release the test seat, thus improving the practicality of the device.
