Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] Please refer to Figures 1-7 The present invention discloses a testing device for an electricity meter circuit board, which consists of six parts, as follows: Figure 1 , Figure 2 , Figure 4As shown, the device includes a base 1, a fixed surface 2, a cylinder 3, a moving contactor 5, a support platform 6, and an elastic ejection assembly 8. A support plate 11 is mounted on the top of the base 1. The fixed surface 2 is mounted on the top of the base 1 and is positioned above the support plate 11. The cylinder 3 is mounted on the side wall of the fixed surface 2. A moving stroke plate 4 is mounted on the output end of the cylinder 3. Several moving contactors 5 are mounted on the bottom of the moving stroke plate 4. The support platform 6 is slidably connected to the top of the support plate 11. A circuit board cavity 7 is opened on the top of the support platform 6. The elastic ejection assembly 8 is located inside the circuit board cavity 7 and is used to eject the circuit board after the test is completed.

[0048] This application features high integration and compact size, allowing it to be placed on a tabletop or desktop. If placed on a desktop, casters can be installed underneath the table for easy movement of the entire device.

[0049] The shape and arrangement of the support plate 11 and the support platform 6 are as follows: Figure 1 As shown. The top of the support platform 6 is provided with four circuit board cavities 7, which can hold four circuit boards for testing at the same time. The top of the support plate 11 is provided with test connection points for contacting the pins or contacts on the circuit boards at positions corresponding to the four circuit board cavities 7.

[0050] The structure of the circuit board cavity 7 is as follows Figure 4 As shown, the circuit board cavity 7 is used to place the circuit board. An opening is provided on the left side of the circuit board cavity 7, which extends through the circuit board cavity 7 and the support platform 6, so that the circuit board can come into contact with the detection device on the top of the support platform 11.

[0051] There are four sets of movable contactors 5, and their positions correspond to the four circuit board cavities 7. Each set has several movable contactors 5. The function of the movable contactors 5 is to press against the top of the circuit board under the drive of the cylinder 3, and push the circuit board and the support platform 6 to move towards the support plate 11 below without damaging the circuit board, so that the circuit board contacts the detection connection point for detection.

[0052] By setting up cylinder 3, support plate 11, support platform 6 and circuit board cavity 7, automatic and precise docking with the test points of the circuit board is achieved, replacing the traditional manual wiring and switching of test modes, which significantly improves test efficiency and consistency.

[0053] By setting up the circuit board cavity 7 and the elastic ejection component 8, the circuit board can be automatically ejected after the test is completed, making it easy for operators to quickly remove the circuit board, improving the efficiency of the test process cycle and effectively reducing the labor intensity of operators.

[0054] Preferably, a through-beam fiber optic sensor 12 for detecting the position of the user's arm is provided on the top of the base 1. When the circuit board is placed or removed, the worker's arm may be below the moving travel plate 4. If the moving travel plate 4 descends at this time, it will cause injury to the worker. By setting the through-beam fiber optic sensor 12, the operating area can be monitored in real time, and the opening timing of the cylinder 3 can be controlled according to the detection results, thereby enhancing operational safety.

[0055] Preferably, the testing device for electricity meter circuit boards further includes a functional test display 13 and an electronic tag reader 14. The functional test display 13 is electrically connected to the testing device for electricity meter circuit boards and is used to display test data. The electronic tag reader 14 is electrically connected to the testing device for electricity meter circuit boards and is used to read electronic tags. By setting up the functional test display 13 and the electronic tag reader 14, real-time visual display of test data and automatic reading and binding of electronic tags are achieved. The test data is directly synchronized to the production management system, reducing the error rate of manual recording. At the same time, the automatic reading function of electronic tags ensures that each circuit board corresponds to one test data, improving the accuracy of quality traceability.

[0056] like Figure 1 , Figure 3 As shown, the top four corners of the support plate 11 are threaded with spacing adjustment bolts 61, and the support platform 6 is slidably connected to the top of the support plate 11 through the spacing adjustment bolts 61. A spacing adjustment spring 62 is provided between the support plate 11 and the support platform 6, and the spacing adjustment spring 62 is sleeved on the outer wall of the spacing adjustment bolt 61.

[0057] In this embodiment, after the movable contactor 5 pushes the circuit board and the support platform 6 to move downwards towards the support plate 11 and completes the detection, the cylinder 3 drives the movable stroke plate 4 to rise. At this time, the spacing adjustment spring 62 will restore its deformation and push the support platform 6 back to the preset position to prepare for the next detection.

[0058] The spacing adjustment bolt 61 is used to adjust the spacing between the support plate 11 and the support platform 6 to accommodate the contact distance required by different types of circuit boards. By setting the spacing adjustment bolt 61 and the spacing adjustment spring 62, this device can adapt to circuit boards of different specifications, improving the versatility of the equipment.

[0059] like Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the elastic ejection assembly 8 includes a through hole 81, a sliding column 82, a lifting column 83, a first spring 85, a locking block 86, a push block 87, an unlocking block 88, a locking column 89, a locking block 91, and a second spring 92. The through hole 81 is formed through the bottom wall of the circuit board cavity 7. The sliding columns 82 are arranged in pairs and are disposed inside the through hole 81. A push plate 84 is formed on the side wall of the lifting column 83. The lifting column 83 is slidably connected to the sliding column 82 through the push plate 84. The first spring 85 is arranged in pairs, sleeved on the outer side wall of the sliding column 82 and disposed below the push plate 84. The locking block 86... 6 is set at the bottom of the lifting column 83. The push block 87 is integrally formed on the side wall of the lifting column 83 and is set above the locking block 86. The unlocking block 88 is slidably connected to the side wall of the lifting column 83 and is set between the locking block 86 and the push block 87. The locking columns 89 are set in pairs and are set at the top of the support plate 11. The side wall of the locking column 89 is provided with a sliding groove 90. The locking block 91 is slidably connected in the sliding groove 90. One end of the second spring 92 is connected to the inner side wall of the sliding groove 90 and the other end of the second spring 92 is connected to the side wall of the locking block 91.

[0060] In this embodiment, the shapes and positions of the through hole 81, lifting column 83, locking block 86, pushing block 87, unlocking block 88, locking column 89, and locking block 91 are as follows: Figure 6 As shown.

[0061] The lifting column 83 is located inside the support platform 6, while the locking column 89 and locking block 91 are located on the top of the support plate 11. Before the test begins, the locking block 86 is above the locking block 91 but not in contact with it. The first spring 85 pushes the push plate 84 to contact the top wall inside the through hole 81. At this time, the top of the lifting column 83 extends into the circuit board cavity 7.

[0062] The usage of the elastic ejection component 8 can be divided into three stages:

[0063] Phase 1: The staff places the circuit board into the circuit board cavity 7. The circuit board presses against the top of the lifting column 83 and drives the lifting column 83 to move downward. The locking block 86 at the bottom of the lifting column 83 moves downward and contacts the locking block 91, pushing the locking block 91 back into the slide groove 90. When the top of the lifting column 83 is flush with the bottom surface of the circuit board cavity 7, the locking block 86 descends below the locking block 91. The second spring 92 pushes the locking block 91 to limit the locking block 86.

[0064] Second stage: Cylinder 3 is activated, and the moving contactor 5 pushes the circuit board and the support platform 6 to move downwards towards the support plate 11. The circuit board in the circuit board cavity 7 contacts the device on top of the support plate 11 and begins detection. During this process, the lifting column 83 moves downwards along with the support platform 6, and the push block 87 pushes the unlocking block 88 to a position slightly lower than the locking block 91, so that the locking block 91 abuts against the side wall of the unlocking block 88. At this time, the state is as follows. Figure 7 As shown.

[0065] Third stage: After the test is completed, the moving contactor 5 moves upward, the spacing adjustment spring 62 pushes the support platform 6 to rise, and at the same time the first spring 85 pushes the push plate 84, so that the top of the lifting column 83 extends into the circuit board cavity 7 and pushes the circuit board out. During this process, the locking block 91 first limits the unlocking block 88, and then the locking block 86 moves upward until it is in close contact with the unlocking block 88, and pushes the unlocking block 88 to move upward together, so that the combination of the locking block 86 and the unlocking block 88 passes over the locking block 91. Finally, the locking block 86 returns to the initial position above the locking block 91 and does not contact it.

[0066] like Figure 6 , Figure 7 As shown, the cross-section of locking block 86 is a trapezoid with an upper base length greater than the lower base length, and the cross-section of unlocking block 88 is a trapezoid with an upper base length less than the lower base length. The shapes of locking block 86 and unlocking block 88 are as follows: Figure 6 , Figure 7 As shown, the shapes of the locking block 86 and the unlocking block 88 can match the locking block 91, driving the locking block 91 to extend and retract within the slide groove 90.

[0067] Preferably, the length of the upper bottom edge of the locking block 86 is slightly less than the length of the lower bottom edge of the unlocking block 88. This ensures that when the locking block 86 moves upward, it can always pass through the position of the locking block 91.

[0068] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
