Description

Technical Field

[0001] This invention relates to the field of electricity meter testing and calibration technology, and more specifically, to a multi-functional calibration device for smart meters. Background Technology

[0002] Multifunctional verification of smart meters refers to the comprehensive testing and verification of their various functions to ensure that key performance indicators such as metering accuracy, communication stability, and data processing capabilities meet relevant standards and specifications. Smart meters typically undergo rigorous verification before leaving the factory to ensure that all functions operate normally and comply with industry standards. Furthermore, regular verification and maintenance are performed during use to promptly identify potential problems, ensure long-term stable operation of the meters, and guarantee the reliability of the power system and the accuracy of data.

[0003] Specifically, the verification process for smart meters involves a verification device using a standard energy meter or a high-precision sampling device to provide a reference electrical energy, which is then compared with the measured value of the meter under test to determine whether the meter's error is within the allowable range. During actual verification, the verification equipment moves the smart meter under test, inserting probes into the meter's terminals and connecting the voltage and current input terminals respectively. Simultaneously, a photoelectric probe is connected to the pulse output window. By providing the required voltage signal and a standard current source, and using the photoelectric sampler to collect pulse data, a small current is applied during this process to detect whether the meter can start normally. Finally, the pulse constant of the smart meter is calculated, and the verification result determines whether the smart meter under test is qualified.

[0004] Manually placing meters for verification is a common method in traditional verification processes, especially suitable for small-scale or non-automated verification scenarios. For example, for non-standard or special-model smart meters, or when the number of meters to be verified is small and equipment resources are limited, large automated equipment may not be suitable, necessitating manual operation to place or remove the meters one by one onto the verification equipment. However, manual placement has significant limitations, such as slow meter placement and retrieval speeds and inaccurate placement positions. These problems easily lead to low verification efficiency and insufficient reliability of results, making it difficult to meet the verification needs of large-volume meters. Therefore, it is necessary to propose a multi-functional smart meter verification device to solve these problems. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a multifunctional smart meter calibration device. This device solves the problems of low efficiency, large errors, and difficulty in meeting the calibration requirements for large batches of smart meters caused by manual placement and retrieval in non-automated smart meter calibration. It has the advantage of being able to complete the placement and retrieval of smart meters in batches, thus improving the calibration efficiency of smart meter calibration equipment.

[0006] To solve the above problems, the present invention adopts the following technical solution: A multi-functional smart meter calibration device includes a loading mechanism, which includes a calibration table. A feeding mechanism is installed on the inclined surface of the calibration table.

A collar is provided inside the front end of the slide plate, a top block is installed outside the collar, and a ramp ring is installed inside the collar.

A stop bar is fixed on the outside of the rack, and the stop bar is rotatably connected to the front end of the slide plate.

[0013] In a preferred embodiment of the present invention, a labeling mechanism is installed inside the skateboard. The labeling mechanism includes a push block installed inside one of the gears. A push bar is slidably connected inside the skateboard near the gear, and the push block abuts against one end of the push bar.

The gear column is meshed with the second toothed plate and the first toothed plate.

[0015] Compared with the prior art, the advantages of this invention are:

[0016] 1. Electricity meters are loaded in batches onto a sliding plate and transported in batches to corresponding pallets. They are then independently sorted based on the calibration results, separating qualified meters from unqualified ones. Finally, all qualified meters are collected together. This process efficiently replaces traditional manual operation, avoiding the tedious steps of manually placing each meter on the calibration table, manually distinguishing between qualified and unqualified meters, and sorting and collecting them. It significantly improves calibration efficiency, reduces errors from manual operation, and lowers labor intensity.

[0017] 2. As the sliding plate slides downwards along the inclined surface of the calibration table, it simultaneously drives the pallet to slide upwards along the same surface, meaning the two move relative to each other and move closer together. This allows the pallet to quickly receive the meter inside the side plate, reducing the sliding plate's travel distance, saving transportation time, and improving calibration efficiency. Furthermore, the mutual contact between the sliding plate and the pallet ensures the meter lands accurately on the pallet, preventing excessive errors in the landing position that could affect the accuracy of the connection between the calibration equipment and the terminals when inserted into the meter. As the pallet moves the meter closer to the calibration equipment, the positioning plate presses against the clamping plate, causing the clamping plate to push the meter to the center of the pallet. This ensures that when the calibration equipment is inserted into the meter, the probes can accurately connect to the corresponding terminals, further guaranteeing the quality and reliability of the calibration process.

[0018] 3. When the meter is conveyed by the feeding mechanism, the contact between the sliding plate and the pallet drives the rotation of the baffle bar and simultaneously drives the labeling mechanism. This causes the pressure plate to automatically retract into the housing, and in conjunction with the rotation of the drum, completes the installation of the new label. Subsequently, during the process of the sliding plate retrieving qualified meters from the pallet, the sliding plate again contacts the pallet, the baffle bar rises, blocking the meter while simultaneously causing the pressure plate to contact the side of the meter. During this movement, the label on the label roll is cut off and affixed to the side of the meter. This automated process not only significantly reduces the labor intensity of manual labeling but also improves the efficiency and accuracy of label application, achieving standardization and high efficiency in meter labeling. During this process, a long rod drives a sliding lever, which in turn pushes a lever block, causing the rotating rod to rotate. This allows the wiping plate to clean the surface of the meter, thereby cleaning the area where the label is to be applied, resulting in a smoother and more secure label application.

[0037] Example 1, please refer to Figures 1 to 16 As shown, the present invention discloses a multi-functional calibration device for smart meters, including a loading mechanism 1. The loading mechanism 1 includes a calibration table 11. A loading mechanism 3 is installed on the inclined surface of the calibration table 11. The loading mechanism 3 includes a support plate 33 installed on the inclined surface of the calibration table 11. A meter 39 is placed on the top surface of the support plate 33. The inclined surface of the calibration table 11 is provided with a pushing mechanism 4. The pushing mechanism 4 includes a slide groove 41 provided on the inclined surface of the calibration table 11. A slider 43 is slidably connected inside the slide groove 41, and a clamping block 45 is installed inside the slider 43. The inclined surface of the calibration table 11 is provided with a flipping mechanism 5. The flipping mechanism 5 includes a flipping chamber 51 located at the top of the inclined surface of the calibration table 11. A flip plate 52 is rotatably connected inside the flipping chamber 51. A motor 53 is installed on the side of the calibration table 11, and the output end of the motor 53 is installed on the side of the flip plate 52. The top surface of the flip plate 52 is provided with a feeding mechanism 6. The feeding mechanism 6 includes several slide plates 61 that are equidistantly installed on the top surface of the flip plate 52. Two side plates 62 are symmetrically arranged on both sides of the top surface of the slide plates 61, and an electric meter 39 is placed between the side plates 62.

[0038] The loading mechanism 1 also includes a feeding conveyor belt 12 installed inside the calibration table 11. A recycling conveyor belt 13 is installed inside the calibration table 11 below the feeding conveyor belt 12. Several first electric push rods 14 are installed at equal intervals on the back of the calibration table 11. A push plate 15 is installed at the output end of the first electric push rod 14, and the push plate 15 is slidably connected to the inside of the calibration table 11. Several partitions 16 are arranged at equal intervals on the feeding conveyor belt 12. The electric meter 39 is placed inside the partition 16. Several channels 17 are arranged at equal intervals inside the calibration table 11. The bottom end of the channel 17 is above the recycling conveyor belt 13.

[0039] A calibration mechanism 2 is installed at the bottom of the inclined surface of the calibration platform 11. The calibration mechanism 2 includes several calibration devices 21 that are equidistantly installed at the bottom of the inclined surface of the calibration platform 11. Two positioning plates 22 are symmetrically installed on the inclined surface of the calibration platform 11 on both sides of each calibration device 21.

[0040] The loading mechanism 3 also includes a support plate 31 and a first spring 32 installed inside the calibration table 11. The support plate 31 is elastically connected to the inside of the calibration table 11 through the first spring 32, and a support plate 33 is installed on the side of the support plate 31. Second springs 34 are installed inside both sides of the support plate 33. Clamping plates 35 are slidably connected to both sides of the support plate 33, and the clamping plates 35 are elastically connected to the support plate 33 through the second springs 34. A rod 36 is installed on the top surface of the support plate 31, and a protrusion 37 is fixed on the cylindrical surface of the rod 36. A first toothed plate 38 is installed on the bottom surface of the support plate 31.

[0041] The feeding mechanism 4 also includes a second electric push rod 42 installed inside the slide 41, and the output end of the second electric push rod 42 is installed on the side of the slider 43. A third spring 44 is installed inside the slider 43, and the clamping block 45 is elastically connected to the inside of the slider 43 through the third spring 44.

[0042] The flipping mechanism 5 also includes a number of third electric push rods 54 that are equidistantly installed on the top surface of the flip plate 52, and the output end of each third electric push rod 54 is installed at the rear end of the slide plate 61. A slot 55 is provided through the flipping compartment 51 at the bottom of each slide plate 61.

[0043] The feeding mechanism 6 also includes a first motor 63 installed inside the frame of the slide plate 61. A discharge plate 64 is rotatably connected inside the slide plate 61, and the output of the first motor 63 drives the discharge plate 64 to rotate. A collar 65 is provided inside the front end of the slide plate 61, a top block 66 is installed outside the collar 65, and a ramp ring 67 is installed inside the collar 65. Two locking blocks 68 are symmetrically fixed to the side of the tail end of the collar 65. Two locking grooves 691 are symmetrically provided inside the front end of the slide plate 61, and the locking blocks 68 engage with the corresponding locking grooves 691. A fourth spring 69 is installed at the tail end of the collar 65. The collar 65 is elastically connected to the front end of the slide plate 61 via the fourth spring 69. Two sets of racks 692 and a fifth spring 693 are symmetrically installed inside the front end of the slide plate 61. The racks 692 are elastically connected to the front end of the slide plate 61 on both sides of the collar 65 via the corresponding fifth spring 693, and the top block 66 abuts against the end of the rack 692. Two gears 694 are symmetrically installed inside the front end of the slide plate 61, and the gears 694 mesh with the corresponding racks 692. A stop bar 695 is fixed to the outside of the rack 692, and the stop bar 695 is rotatably connected to the front end of the slide plate 61.

[0044] A transmission mechanism 8 is provided on the inclined surface of the calibration table 11. The transmission mechanism 8 includes a long groove 81 on the inclined surface of the calibration table 11. A second toothed plate 82 and a ninth spring 83 are installed in the long groove 81. The second toothed plate 82 is elastically connected to the inside of the long groove 81 through the ninth spring 83. A gear column 84 is installed inside the bottom end of the calibration table 11. The gear column 84 is meshed with the second toothed plate 82 and the first toothed plate 38.

[0045] Each slot 16 on the discharge conveyor belt 12 contains an electric meter 39. Initially, the flip plate 52 is horizontally positioned within the tilting chamber 51, and the feeding conveyor belt 12 rolls inside the calibration table 11, stopping at regular intervals. Each time it stops, several slots 16 on the top surface of the feeding conveyor belt 12 correspond one-to-one with the position of each slide plate 61 on the flip plate 52. Then, the first electric push rod 14 is activated, driving the push plate 15 to push the electric meter 39 inside each slot 16 into the side plate 62 on the top of the corresponding slide plate 61, until the bottom of the electric meter 39 touches the stop bar 695 (initially, the stop bar 695 is perpendicular to the top surface of the slide plate 61).

[0046] After the meter 39 enters the side plate 62, the motor 53 drives the flip plate 52 to reverse, causing the flip plate 52 and the pushing mechanism 4 to tilt at the same angle as the inclined surface of the inspection table 11 (as shown in the attached figure). Figure 2(As shown), then the third electric push rod 54 is activated, pushing the slide plate 61 to slide down the slope of the calibration table 11. The slide plate 61 moves with the meter 39. Since the clamping block 45 protrudes from the slope of the calibration table 11 and is on the moving path of the slide plate 61, the front end of the slide plate 61 will abut against the clamping block 45 during the sliding process. Since the clamping block 45 is set as a slope, the slide plate 61 pressing the clamping block 45 will cause the clamping block 45 to slide into the slider 43 and compress the third spring 44, so that the clamping block 45 sinks into the slope of the calibration table 11, thereby avoiding obstructing the movement of the slide plate 61.

[0047] Finally, the front end of the slide plate 61 comes into contact with the support plate 33 located at the bottom of the inclined surface of the calibration table 11. During the contact process, the insert rod 36 on the top surface of the support plate 31 is inserted into the collar 65 at the front end of the slide plate 61, and the protrusion 37 on the cylindrical surface of the insert rod 36 comes into contact with the ramp ring 67 on the inner wall of the collar 65 (the ramp ring 67 is formed by connecting two semi-circular structures with inclined ends). Because the locking block 68 at the tail end of the collar 65 is engaged in the locking groove 691, the collar 65 can only slide horizontally and cannot rotate axially. Therefore, when the insert rod 36 initially enters the collar 65, although the protrusion 37 abuts against the ramp ring 67, it cannot drive the collar 65 to rotate. Instead, under the pushing force of the protrusion 37, it slides a certain distance deeper into the slide plate 61, causing the collar 65 to compress the fourth spring 69, and the locking block 68 to disengage from the locking groove 691. Subsequently, the protrusion 37 squeezes the ramp ring 67, causing the collar 65 to rotate half a turn. The collar 65 pushes the rack 692 to slide through the top block 66. The rack 692 compresses the fifth spring 693 while driving the gear 694 to rotate, thereby causing the stop bar 695 to rotate ninety degrees, changing from vertical to parallel to the top surface of the slide plate 61. Without the obstruction of the stop bar 695, the meter 39 inside the side plate 62 completely abuts against the support plate 33. Next, the third electric push rod 54 shortens, causing the slide plate 61 to return, leaving the meter 39 on the support plate 33. During the return process, the insert rod 36 is pulled out of the collar 65. During this process, the elastic force of the collar 65 causes the collar 65 to slide along with the insert rod 36, and the locking block 68 slides back into the locking groove 691, thereby locking the collar 65 and preventing it from rotating. Therefore, during the reset process of the slide plate 61, the rack 692 is abutted by the top block 66 and cannot move, thus fixing the gear 694 and the stop bar 695, keeping the stop bar 695 parallel to the top surface of the slide plate 61.

[0048] During the process of transporting the meter 39, the slide plate 61 always abuts against the clamping block 45, keeping the clamping block 45 inside the slider 43. When the slide plate 61 returns to its original position and no longer abuts against the clamping block 45, the third spring 44 pushes the clamping block 45 out of the slider 43. Subsequently, the second electric push rod 42 extends, pushing the slider 43 to slide in the slide groove 41, and causing the clamping block 45 to abut against the meter 39 on the support plate 33. The slider 43 continues to slide, and the clamping block 45 pushes the meter 39 and the support plate 33 together to move towards the bottom of the inclined surface of the calibration table 11. The support plate 33 drives the support plate 31 to slide inside the calibration table 11. The support plate 31 compresses the first spring 32 and drives the first toothed plate 38 to move synchronously. The first toothed plate 38 separates from the gear column 84. Finally, the meter 39 is lowered into the bottom of the calibration device 21 for calibration (the calibration device 21 is equipped with various probes required for calibration, such as voltage probes, current probes, photoelectric probes, and grounding probes, which are connected to the voltage and current input terminals, pulse output port, and grounding terminal of the meter 39, respectively).

[0049] After the verification is completed, the second electric push rod 42 shortens, causing the slider 43 and clamp 45 to return. Without the resistance of the clamp 45, the support plate 31 and tray 33 reset under the elastic force of the first spring 32. After the verification is completed, the verification equipment 21 calculates the pulse constant of the meter 39 and determines whether the current verification object is qualified based on the comparison results, and sends different signals to the third electric push rod 54. If the test fails, the third electric push rod 54 will not activate; if the test succeeds, the third electric push rod 54 will activate, causing the slide plate 61 to slide down the inclined surface of the calibration table 11 again. When the front end of the slide plate 61 touches the support plate 33 again, the side plate 62 will wrap around the meter 39 on the support plate 33, and the insert rod 36 will be inserted into the collar 65 again, causing the collar 65 to rotate half a turn, causing the top block 66 to no longer touch the rack 692. Then, under the rebound force of the fifth spring 693, the rack 692 will drive the gear 694 to reverse, rotating the stop bar 695 back to be perpendicular to the top surface of the slide plate 61, and blocking the bottom of the meter 39 again (as per the instruction manual). Figure 7 As shown, the top surface of the tray 33 has grooves on both sides. The front end of the slide plate 61 abuts against the higher position of the top surface of the tray 33. The groove allows the stop bar 695 to rotate freely, so that the stop bar 695 can smoothly block the bottom of the meter 39. In this way, when the slide plate 61 is reset, it can drive the meter 39 into the tilting chamber 51 together.

[0050] After the slide plate 61 returns to the flip plate 52, the motor 53 drives the flip plate 52 to reset (return to the initial horizontal position), causing the meter 39 inside the side plate 62 to enter the flip chamber 51. Subsequently, the first motor 63 drives the unloading plate 64 to rotate, emptying the middle of the slide plate 61 (as per the instruction manual). Figure 10As shown), it is connected to the corresponding channel 17. The meter 39 in the side plate 62 slides into the channel 17 along the inclined surface formed by the unloading plate 64, and finally reaches the recycling conveyor belt 13 and is transported out by the recycling conveyor belt 13.

[0051] Electricity meters 39 are loaded in batches onto the slide plate 61 and transported in batches to the corresponding pallets 33. They are then independently sorted according to the verification results, separating qualified meters 39 from unqualified ones. Finally, all qualified meters are collected together. This process efficiently replaces traditional manual operation, avoiding the tedious steps of manually placing each meter 39 on the verification table 11, manually distinguishing between qualified and unqualified meters, and sorting and collecting them. It significantly improves verification efficiency, reduces errors from manual operation, and lowers labor intensity. Moreover, compared to fully automated verification, this solution is smaller in scale and lower in cost, making it suitable for small-scale or special-model smart meter verification.

[0052] During the process of the third electric push rod 54 pushing the slide plate 61 down, the outer shell 74 on the side of the side plate 62 will abut against the second toothed plate 82 exposed from the long groove 81 halfway down. (The second toothed plate 82 has an L-shaped structure, with its short end slidably connected to the long groove 81 and its long end slidably connected to the inside of the calibration table 11. It has teeth on its surface and meshes with the gear column 84. It should be noted that initially, the second toothed plate 82 does not mesh with the gear column 84. Only after the outer shell 74 pushes the second toothed plate 82 to slide a certain distance will the second toothed plate 82 mesh with the gear column 84. This is because the first toothed plate 38 also meshes with the gear column 84. During the calibration stage, the first toothed plate 38 slides down with the support plate 31, which will drive the gear column 84 to rotate. At this time, the gear column 84 does not mesh with the second toothed plate 82, so it will not drive the second toothed plate 82 to move. Therefore, it reduces the movement of parts to a certain extent, reduces interference between mechanisms, and improves the service life of parts.) The outer casing 74 pushes the second toothed plate 82 to slide within the long slot 81 and compresses the ninth spring 83. Subsequently, the second toothed plate 82 meshes with the gear column 84, causing the support plate 31 to slide upward along the inclined surface of the calibration table 11 by driving the gear column 84 to rotate. The support plate 31 stretches the first spring 32 while driving the support plate 33 to move together. The support plate 33 and the slide plate 61 move relative to each other and move closer to each other, so that the support plate 33 can quickly receive the meter 39 in the side plate 62, reduce the moving distance of the slide plate 61, save transportation time, and improve calibration efficiency. Moreover, the handover of the meter 39 is completed by the mutual contact between the slide plate 61 and the support plate 33, which can also ensure that the meter 39 falls accurately onto the support plate 33, avoiding excessive error in the falling position, which would affect the accuracy of the calibration equipment 21 inserting into the meter 39 and connecting with the terminal.

[0053] To ensure that the probes on the calibration equipment 21 can accurately connect with the corresponding terminals inside the meter 39, thereby improving calibration quality and reliability, clamping plates 35 are provided on both sides of the tray 33. When the tray 33 moves the meter 39 closer to the calibration equipment 21, the clamping plates 35 are first squeezed by the positioning plates 22 on the inclined surfaces of the calibration table 11 on both sides of the calibration equipment 21, causing the clamping plates 35 to move closer to the center of the loading mechanism 3, compressing the second spring 34 inside the tray 33, and squeezing the side of the meter 39, so that the meter 39 falls accurately into the center position of the tray 33. Thus, when the calibration equipment 21 is inserted into the meter 39, the probes can accurately connect with the corresponding terminals, thereby ensuring calibration reliability.

[0054] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 16 The labeling mechanism 7 is installed inside the slide plate 61. The labeling mechanism 7 includes a push block 71 installed inside one of the gears 694. A pusher bar 72 is slidably connected inside the slide plate 61 near the gear 694, with the push block 71 abutting one end of the pusher bar 72. A long rod 73 is slidably connected inside the frame of the slide plate 61 near the pusher bar 72, with one end of the long rod 73 abutting the other end of the pusher bar 72. A housing 74 is installed on the side of the side plate 62. A transmission block 75 and a sixth spring 76 are installed inside the housing 74. The transmission block 75 is elastically connected to the inside of the housing 74 via the sixth spring 76, and the other end of the long rod 73 abuts the bottom inclined surface of the transmission block 75. A pressure plate 77 is installed on the top of the transmission block 75. A lever 78 is fixed to the top surface of the other end of the long rod 73. A second motor 79 and two rollers 791 are installed inside the housing 74. The output end of the second motor 79 is installed at the bottom of one of the rollers 791. Label rolls 792 are wound on the two rollers 791. A glue box 793 is also installed inside the housing 74. A glue roller 794 is rotatably connected to the bottom of the glue box 793, and the glue roller 794 abuts against the label rolls 792. A rotating rod 795 is rotatably connected inside the housing 74. A torsion spring 796 is sleeved on the rotating rod 795, and the rotating rod 795 is elastically connected to the inside of the housing 74 through the torsion spring 796. A lever 798 is provided at the bottom of the rotating rod 795. A wiping plate 797 is installed at one end of the rotating rod 795 that passes through the housing 74.

[0055] After the inspection is completed, qualified meters 39 need to be labeled with a qualified label. This step is usually done manually, which is not only labor-intensive but also time-consuming, reducing the efficiency of the inspection. Therefore, a labeling mechanism 7 is installed on the outside of the side panel 62. Inside the outer casing 74, a label roll 792 (consisting of a label with the word "qualified" printed on it and a backing paper) is wound on the drum 791 with the second motor 79 installed. When the second motor 79 is started, it drives the corresponding drum 791 to rotate, which can roll up the used label roll 792 (i.e., the backing paper without the label) and drag the label roll 792 to release the label roll 792 from the other drum 791 (the drum 791 without the second motor 79 has a certain frictional resistance when rotating, which can prevent the label roll 792 from rotating due to the pulling force when the pressure plate 77 cuts the label).

[0056] When the slide plate 61 moves the meter 39 onto the tray 33, the stop bar 695 rotates to be parallel to the top surface of the slide plate 61. During this process, the gear 694 drives the push block 71 to rotate, so that the push block 71 no longer resists the push bar 72. Then, under the elastic force of the sixth spring 76, the transmission block 75 is pulled back. The transmission block 75 drives the pressure plate 77 away from the meter 39 and back into the housing 74. Then, the second motor 79 starts, driving the corresponding drum 791 to rotate, driving the label roll 792 to be released. The label roll 792 with the new label moves to the moving path of the pressure plate 77. After the inspection is completed, the slide plate 61 receives the qualified meter 39, and the front end of the slide plate 61 again... When the meter 39 is pressed against the tray 33, the stop bar 695 rotates to a position perpendicular to the top surface of the slide plate 61. The pusher block 71 inside the slide plate 61 pushes the push bar 72 to slide, causing the other end of the long rod 73 to press against the transmission block 75. The transmission block 75 stretches the sixth spring 76 and drives the pressure plate 77 to slide out from the outer casing 74, pressing against the side of the meter 39. As the transmission block 75 drives the pressure plate 77 to move, it can press against the label roll 792 located on the moving path of the pressure plate 77, cutting off the label on the label roll 792 and pressing it against the side of the meter 39 (the pressure plate 77 uses electrostatic adsorption to hold the label in place, preventing the label from falling off), thus completing the labeling process. This automatic labeling process, which uses the feeding mechanism 6 to transport the meter 39 and collect qualified meters 39, not only significantly reduces the labor intensity of manual labeling but also improves the efficiency and accuracy of labeling, achieving standardization and high efficiency in meter labeling.

[0057] As can be seen from the above, when the slide plate 61 receives a qualified meter 39, the stop bar 695 will only move after the meter 39 is fully inside the side plate 62. That is, the process of the stop bar 695 rotating from horizontal to vertical will drive the long rod 73 to squeeze the transmission block 75. The long rod 73 will simultaneously drive the lever 78 to move, thereby contacting the lever 798 and causing the rotating rod 795 to rotate. The rotating rod 795 will cause the torsion spring 796 to store force while driving the wiping plate 797 to swing. Moreover, the wiping plate 797 swings before the pressure plate 77 contacts the side of the meter 39 (it takes a certain amount of time for the pressure plate 77 to slide out of the outer casing 74, and the contact time between the lever 78 and the lever 798 is shorter and the response is faster). In this way, the wiping plate 797 can clean the side of the meter 39 before the label on the pressure plate 77 is affixed to the meter 39, thereby cleaning the label affixed area of ​​the meter 39 and making the label affixed more flat and firm.
