Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meter processing, and in particular to a device for processing scrapped electric energy meters. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy or various electrical quantities. However, due to the long-term use of electric energy meters, they may be damaged, so damaged electric energy meters need to be scrapped and recycled. According to regulations, when handling scrapped electric energy meters, they need to be destroyed to ensure that the scrapped electric energy meters cannot be reused. The traditional method of destroying scrapped electric energy meters is to manually open holes for destruction and manually perform laser coding to mark the surface of the electric energy meters. This is inefficient and unsafe. In addition, there is no archiving record for scrapped electric energy meters, which results in the tracing and query of scrapped electric energy meters. This cannot effectively meet the current needs of the State Grid for electric energy meter asset management. Therefore, it is necessary to develop a scrapped electric energy meter processing device that is efficient, simple to operate, safe and stable. Summary of the Invention

DETAILED DESCRIPTION

[0038] In order to facilitate understanding of the technical solution of the present invention, a detailed description is given below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] like Figure 1-Figure 2 As shown, a scrapped electricity meter disposal device includes a profile frame 1 and a conveyor line 2 arranged below the profile frame 1, and a first filing mechanism 3, a punching mechanism 4, an engraving mechanism 5 and a second filing mechanism 6 are arranged in sequence on the profile frame 1; the engraving mechanism 5 includes an engraving machine body 5-1 and a first driving mechanism 5-2 for driving the engraving machine body 5-1 to move.

[0041] The profile frame 1 is provided with a stopping mechanism and a positioning mechanism for preventing the electric energy meter from moving, which can position the electric energy meter and improve the accuracy of drilling by the punching mechanism 4 and laser engraving by the engraving mechanism 5.

[0042] The punching mechanism 4 includes a three-axis moving component 4-1 and a drill bit 4-2 located on the three-axis moving component 4-1. The height and position of the drill bit 4-2 are controlled by the three-axis moving component 4-1, and the drill bit is controlled by a high-speed motor to rotate to punch holes in the electricity meter; the conveyor line 2 includes a conveyor frame 2-1 and two conveyor belts 2-2 located on the conveyor frame 2-1. The area between the two conveyor belts 2-2 is where the electricity meter is placed, and an exhaust outlet is formed between the two conveyor belts 2-2.

[0043] like Figure 12 As shown, the conveyor frame 2-1 is also equipped with several clamping cylinders 2-3 arranged side by side. The driving ends of the clamping cylinders 2-3 are equipped with drive plates 2-4. Flexible pressure strips 2-5 are connected between adjacent drive plates 2-4. The extended length of each clamping cylinder 2-3 can be different to clamp electricity meters of different specifications and sizes, and can be compatible with single-phase meters, three-phase cost control meters, and three-phase multi-function meters. The flexible pressure strips 2-5 can have a certain degree of elasticity to facilitate clamping the electricity meter while reducing vibration during drilling. In addition, the flexible pressure strips 2-5 are detachable and can be set at different heights according to the height of the electricity meter.

[0044] The first archiving mechanism 3 and the second archiving mechanism 6 include industrial cameras that can read the barcode of the electricity meter before it is scrapped and archive it.

[0045] The engraving machine body has a laser lens, which is replaceable. The laser lens of appropriate size can be selected according to the size of single-phase meter, three-phase meter and terminal meter, so that the engraving range can cover any single-phase meter, three-phase meter and terminal meter.

[0046] The first driving mechanism is a z-axis lifting mechanism. According to the first filing mechanism, the engraving machine body can automatically identify the type of electricity meter, and the z-axis upgrading mechanism automatically adjusts the focal length of the engraving machine to target the height deviation of different meters.

[0047] During operation, the electric energy meter is transported in the device through the conveyor line, first transported to the photo-taking and archiving station to take photos and archive them before destruction through the first archiving mechanism, and after archiving is completed, it is transported to the drilling and destruction station to drill holes in designated positions through the punching mechanism 4, and after drilling, it is transported to the coding station to engrave designated characters at designated positions through the engraving mechanism 5, and finally transported to the scrapping and archiving station to take photos and archive them through the second archiving mechanism.

[0048] Example 2

[0049] like Figure 3 As shown, the profile frame 1 is further provided with an exhaust gas absorption mechanism 7 matching the engraving mechanism 5, which can absorb the exhaust gas and dust generated after laser engraving.

[0050] like Figure 4 As shown, the exhaust gas absorption mechanism 7 includes an exhaust gas box 7-1 arranged on the profile frame 1, an exhaust gas cover 7-2 arranged on the exhaust gas box 7-1, and an exhaust gas hood arranged on the lower surface of the workbench 1-1 of the profile frame 1, and a driving pipe 7-3 is provided between the exhaust gas hood and the exhaust gas cover 7-2; wherein, the workbench 1-1 is provided with a plurality of exhaust gas holes, and the exhaust gas holes are distributed below the engraving mechanism 5 and in front of the moving position of the electric energy meter. For example, there are 6 exhaust gas holes below the engraving mechanism 5, and 4 exhaust gas holes are provided in front of the 6 exhaust gas holes. During engraving, the electric energy meter is located in the area surrounded by the 6 exhaust gas holes below the engraving mechanism 5. The exhaust gas generated during engraving generally enters the exhaust gas absorption mechanism 7 through the 6 exhaust gas holes. When engraving is completed, the electric energy meter moves forward driven by the conveyor line 2, and the residual exhaust gas and dust on the electric energy meter can be absorbed through the 4 exhaust gas holes in the front. In this embodiment, during engraving, the exhaust hood is positioned below the six exhaust holes to absorb exhaust gas from the engraving process. After engraving is completed, when the energy meter moves forward to the area of ​​the four exhaust holes, the exhaust box 7-1 drives the exhaust hood to simultaneously move below the four exhaust holes to absorb any residual exhaust gas and dust from the energy meter. In other words, the exhaust hood and exhaust box 7-1 in this application can move synchronously. For example, both the exhaust hood and exhaust box 7-1 can be slidably engaged with the profile frame 1 via a slide rail and slider assembly. The specific structure is conventional in the art and will not be described in detail.

[0051] In addition, the driving pipe 7-3 can be set as a rigid straight pipe, so that the exhaust box 7-1 can move while pushing the exhaust cover to move. Alternatively, the exhaust box 7-1 and the exhaust cover are both provided with a driving structure such as a cylinder.

[0052] The exhaust port, exhaust hole, exhaust hood, drive pipe 7-3, exhaust cover 7-2 and exhaust box 7-1 form an exhaust passage, and the exhaust gas can be collected or discharged into the air after passing through the exhaust passage.

[0053] Specifically, the exhaust box 7-1 has vertically distributed first, second, and third areas. The first area houses a first process cartridge 7-4, the second area houses a second process cartridge 7-5, and the third area houses a third process cartridge 7-6. The structures of the first, second, and third process cartridges 7-4, 7-5, and 7-6 are nearly identical, differing only in the exhaust gas treatment components within them. The first, second, and third process cartridges 7-4, 7-5, and 7-6 are approximately disc-shaped in shape. For example, the first process cartridge 7-4 comprises a central process cartridge body and connecting portions at the upper and lower ends of the process cartridge body, namely an upper connecting portion and a lower connecting portion. Both the process cartridge body and the connecting portion are oblate cylindrical structures, with the diameter and height of the process cartridge body being greater than those of the connecting portions. The interior of the first process cartridge 7-4 is hollow, with a first exhaust gas inlet 7-4-1 located on the upper connecting portion and a first exhaust gas outlet 7-4-2 located on the lower connecting portion. The first exhaust gas treatment component is housed within the hollow portion of the process cartridge body. Exhaust gas enters the cavity of the upper connecting portion through the first exhaust gas inlet 7-4-1, is treated by the first exhaust gas treatment assembly, and then enters the cavity of the lower connecting portion. Finally, it is discharged into the second processing box 7-5 through the first exhaust gas outlet 7-4-2. The second processing box 7-5 and the third processing box 7-6 have the same external structure, so the exhaust gas circulation method will not be further described.

[0054] To sum up, the first waste gas inlet 7-4-1 of the first processing box 7-4 is connected to the waste gas cover 7-2 through a hose, the first waste gas outlet 7-4-2 of the first processing box 7-4 is connected to the second waste gas inlet 7-5-1 of the second processing box 7-5 through a hose, the second waste gas outlet 7-5-2 of the second processing box 7-5 is connected to the third waste gas inlet 7-6-1 of the third processing box 7-6 through a hose, the third waste gas outlet 7-6-2 of the third processing box 7-6 is connected to the waste gas outlet 7-1-1 of the waste gas box 7-1, and the treated waste gas can be discharged into the air or into a collection box through the waste gas outlet 7-1-1.

[0055] like Figure 6 As shown, in this embodiment, two layers of supporting protrusions 7-1-2 are provided in the first area, the second area and the third area, and the supporting protrusions 7-1-2 of each layer in the same area are arranged opposite to each other; taking the first area as an example, two layers of supporting protrusions 7-1-2 arranged opposite to each other are provided in the first area, and each layer of supporting protrusions 7-1-2 has four supporting protrusions 7-1-2 and is evenly distributed on the inner wall of the exhaust box 7-1, and the ends of the supporting protrusions 7-1-2 are provided with recesses 7-1-3, and the two layers of supporting protrusions 7-1-2 arranged opposite to each other enclose an accommodating space for accommodating the first processing cartridge 7-4; as shown Figure 7As shown, a crankshaft 7-7 is rotatably fitted in the exhaust box 7-1, and a bent accommodating portion 7-7-1 is provided on the crankshaft 7-7 for accommodating the first processing box 7-4, the second processing box 7-5 and the third processing box 7-6 respectively. Specifically, the lower end of the crankshaft 7-7 is rotatably fitted in the bottom of the exhaust box 7-1, and has three bent accommodating portions 7-7-1 bent outward and inward. The crankshaft 7-7 extends upward from the bottom of the exhaust box 7-1 to the top of the exhaust box 7-1, passing through the first area, the second area and the third area; the first processing box 7-4 is arranged in the first bent accommodating portion at the top, as shown in FIG. Figure 5 As shown, a push key 8 is provided between the first curved accommodating portion and the corresponding process cartridge, which drives the process cartridge to rotate about the rotation center of the crankshaft 7-7. That is, during use, rotating the crankshaft 7-7 can drive the first process cartridge 7-4 to rotate via the push key 8. Similarly, the second curved accommodating portion located in the middle of the crankshaft 7-7 houses the second process cartridge 7-5, with a push key 8 located between the second curved accommodating portion and the second process cartridge 7-5. The third curved accommodating portion located in the lower portion of the crankshaft 7-7 houses the third process cartridge 7-6, with a push key 8 located between the third curved accommodating portion and the third process cartridge 7-6. Rotating the crankshaft 7-7 can cause the first, second, and third process cartridges 7-4, 7-5, and 7-6 to rotate simultaneously via the push key 8, thereby urging exhaust gas and dust to flow within the corresponding process cartridges and more effectively treating impurities such as exhaust gas. In this embodiment, a rotary motor can be provided at the bottom of the exhaust gas box 7-1 to drive the crankshaft 7-7.

[0056] In addition, the upper and lower corners of the first bent accommodating portion respectively fit over the clearance notches 7-1-3 of the two layers of support protrusions 7-1-2 in the first region, supporting and guiding the first bent accommodating portion through the clearance notches 7-1-3. Preferably, multiple first bent accommodating portions can be provided on the crankshaft 7-7 at the same height as the first bent accommodating portion. This facilitates the fit between the first bent accommodating portion and the clearance notches 7-1-3 and improves the stability between the first process cartridge 7-4 and the first bent accommodating portion. Similarly, multiple second and third bent accommodating portions can be provided at corresponding heights on the crankshaft 7-7.

[0057] The first curved accommodating portion has a stepped structure at its upper and lower corners, which not only conform to the surface of the clearance notch 7-1-3 but also to the surface of the support protrusion 7-1-2, thereby improving stability during rotation. A support pad 11 is provided between the first curved accommodating portion and the first process cartridge 7-4. One or more support pads 11 may be provided. Similarly, the structures of the second and third curved accommodating portions are similar to those of the first curved accommodating portion and will not be further described.

[0058] In this embodiment, a first partition wall is provided at the top of the first area, a second partition wall is provided at the top of the second area, and a third partition wall is provided at the top of the third area. A rotating disk 9 is provided within the exhaust gas box 7-1. The rotating disk 9 includes a first rotating disk 9-1 provided on the first partition wall, a second rotating disk 9-2 provided on the second partition wall, and a third rotating disk 9-3 provided on the third partition wall. The first rotating disk 9-1, the second rotating disk 9-2, and the third rotating disk 9-3 are rotatably engaged with the first partition wall, the second partition wall, and the third partition wall, respectively. Taking the first rotating disk 9-1 as an example, limiting protrusions are provided at both ends of the first rotating disk 9-1, and limiting grooves are provided at corresponding positions on the first partition wall, which can support the first rotating disk 9-1 while preventing the first rotating disk 9-1 from detaching from the first partition wall. The crankshaft 7-7 is arranged to pass through the second rotating disk 9-2 and the third rotating disk 9-3, and the crankshaft 7-7 has a rotating protrusion 7-7-2 at the corresponding position on the second rotating disk 9-2 and the third rotating disk 9-3. The surface of the rotating protrusion 7-7-2 is provided with a pushing protrusion 7-7-3. The pushing protrusion 7-7-3 can push the second rotating disk 9-2 and the third rotating disk 9-3 to rotate as the crankshaft 7-7 rotates. The top of the first bent accommodating portion has a pushing protrusion 7-7-4, and the corresponding position of the lower end of the first rotating disk 9-1 has a mounting groove 9-1-1. When the crankshaft 7-7 rotates, the pushing protrusion 7-7-4 can cooperate with the mounting groove 9-1-1 to rotate the first rotating disk 9-1.

[0059] Since the first processing box 7-4, the second processing box 7-5, the third processing box 7-6, the first rotating disk 9-1, the second rotating disk 9-2 and the third rotating disk 9-3 will all rotate with the rotation of the crankshaft 7-7, hose connecting ports are provided on the first rotating disk 9-1, the second rotating disk 9-2 and the third rotating disk 9-3. The hose connecting port of the first rotating disk 9-1 is connected to the first exhaust gas inlet 7-4-1 of the first processing box 7-4 through a hose, the first exhaust gas outlet 7-4-2 of the first processing box 7-4 is connected to the hose connecting port of the second rotating disk 9-2 through a hose, the hose connecting port of the second rotating disk 9-2 is connected to the second exhaust gas inlet 7-5-1 of the second processing box 7-5 through a hose, the second exhaust gas outlet 7-5-2 of the second rotating disk 9-2 is connected to the hose connecting port of the third rotating disk 9-3 through a hose, and the hose connecting port of the third rotating disk 9-3 is connected to the third exhaust gas inlet 7-6-1 of the third processing box 7-6 through a hose.

[0060] An exhaust gas outlet 7-1-1 is provided on the inner wall of the third area in the exhaust gas box 7-1, and an air pump is connected to the exhaust gas outlet to absorb exhaust gas and other impurities from the engraving station into the exhaust gas box 7-1.

[0061] A fourth processing box 7-8 is provided in the third area near the exhaust outlet 7-1-1. The exhaust port, exhaust hole, exhaust cover, drive pipe 7-3, exhaust cover 7-2, first processing box 7-4, second processing box 7-5, third processing box 7-6, fourth processing box 7-8 and exhaust box 7-1 form an exhaust channel. After the impurities are processed by the first processing box 7-4, second processing box 7-5, third processing box 7-6 and fourth processing box 7-8, they can be directly discharged into the air or discharged into an additional collection box. Among them, the exhaust gas treatment components in the first processing box 7-4, the second processing box 7-5, the third processing box 7-6 and the fourth processing box 7-8 can be set according to usage requirements, such as filter screens, activated carbon layers, etc.; in this embodiment, the first processing box 7-4 is provided with a filter screen or a cyclone separator to remove large particles and some dust in the exhaust gas to reduce the burden on subsequent processing equipment; the second processing box 7-5 adopts HEPA high-efficiency filter elements and other filter materials to filter tiny particles in the exhaust gas to ensure that the particulate matter in the exhaust gas meets the emission standards; the third processing box 7-6 has an activated carbon layer, which uses the adsorption properties of activated carbon to adsorb organic matter and odor in the exhaust gas.

The first piston 10-2 is slidably fitted in the first piston pipe 10-4, and the second piston 10-3 is slidably fitted in the second piston pipe 10-5. The hydraulic pipe 10-1 is filled with hydraulic oil. Figure XAs shown in Figure 1, after laser engraving is completed, the first drive mechanism 5-2 drives the engraving machine body 5-1 upward, thereby driving the first piston 10-2 to rise in the first piston tube 10-4. The hydraulic oil drives the second piston 10-3 to move rightward in the second piston tube 10-5, thereby pushing the exhaust gas box 7-1 to move rightward. After laser engraving is completed, the engraved energy meter is transported to the right by the conveyor belt 2-2 to the bottom of the second archiving mechanism 6 for photographing and archiving. As the energy meter moves to the right, the first drive mechanism 5-2 drives the engraving machine body 5-1 upward, thereby pushing the exhaust gas box 7-1 forward in the direction of the energy meter's movement through the hydraulic assembly 10, thereby driving the exhaust gas hood to move rightward through the drive tube 7-3, so that the exhaust gas hood moves from below the six exhaust gas holes on the left to below the four exhaust gas holes on the right, absorbing the residual exhaust gas on the energy meter. In addition, the speed of the conveyor belt 2-2 can be set to be variable, that is, it has a certain acceleration, which can be positive or negative, so that impurities such as exhaust gas on the electricity meter can move relative to each other due to inertia and fall into the exhaust hood. When the next electricity meter moves to the engraving station, the first drive mechanism 5-2 drives the engraving machine body 5-1 to move downward, and drives the exhaust box 7-1 to move leftward and back to under the electricity meter to be engraved through the hydraulic assembly 10 to collect the exhaust gas.

[0063] Example 3

[0064] like Figure 11As shown, the drill bit 4-2 is covered with a waste collection box 12. The waste collection box 12 has a cylindrical cover structure with a through hole in the middle to accommodate the drill bit 4-2. The through hole is slightly larger than the diameter of the drill bit 4-2 to prevent the drill bit 4-2 from rotating and rubbing against the waste collection box 12, or cutting the waste collection box 12. The waste collection box 12 has an outlet 12-1 connected to a slag suction pipe 13 on one side. The slag suction pipe 13 is connected to a waste collection box via an air pump. The waste collection box is used to store waste chips generated by drilling. The waste collection box 12 and the slag suction pipe 13 can be connected by bolts or clamping. The waste collection box 12 is equipped with a chip remover 14 for removing waste chips from the surface of the drill bit 4-2. Specifically, the chip remover 14 is sleeved on the outside of the drill bit 4-2, and the middle part of the chip remover 14 has a through hole for accommodating the drill bit 4-2. The size of the through hole is slightly larger than the diameter of the drill bit 4-2. The outer surface of the chip remover 14 is connected to the inner wall of the waste chip collection box 12 through a connecting rod; the chip remover 14 has a first chip removal protrusion 14-1 at the lower end, a second chip removal protrusion 14-2 at the upper end and a collection groove 14-3 connected to the second chip removal protrusion 14-2. The first chip removal protrusion 14-1 extends downward, and the length can be 2-5 cm, with a certain inclined surface or arc surface. When the drill bit 4-2 moves upward relative to the waste chip collection box 12, the long waste chips on the drill bit 4-2 will contact the first chip removal protrusion 14-1 and be scraped off by the first chip removal protrusion 14-1. Part of the scraped waste chips can enter the waste chip box at the rear end through the slag suction pipe 13, and the other part may fall. The second chip removal protrusion 14-2 is located above the first chip removal protrusion 14-1, and its structure is similar to that of the first chip removal protrusion 14-1. The collecting groove 14-3 is an annular structure, and the collecting groove 14-3 is connected to the outlet 12-1. The waste chips in the collecting groove 14-3 can enter the waste chip box at the rear end through the slag suction pipe 13; there is at least one brush body 15 above the chip removal member 14, and the bristle part of the brush body 15 fits the surface of the drill bit 4-2. When the drill bit 4-2 moves upward relative to the waste chip collection box 12, the brush body 15 can clean the waste chips in the spiral groove of the drill bit 4-2. When the waste chips are cleaned up by the brush body 15, they will contact the second chip removal protrusion 14-2 and be introduced into the collecting groove 14-3 by the second chip removal protrusion 14-2. The waste chips in the collecting groove 14-3 can enter the waste chip collection box at the rear end through the slag suction pipe 13.
