DETAILED DESCRIPTION

[0018] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0019] Figure 1 A schematic diagram of the structure of an electric energy meter scrapping device provided by an embodiment of the present invention, Figure 5 Another structural schematic diagram of an electric energy meter scrapping device provided by an embodiment of the present invention is as follows Figure 1 and Figure 5 As shown, the device includes a stacker 100, a chassis 13, a laser 15, and an exhaust assembly 17, wherein: The stacker 100 places the turnover box 21 on the conveyor belt 102, and the conveyor belt 102 moves under the drive of the motor, and then transports the turnover box 21 into the chassis 13, wherein the turnover box 21 contains a plurality of electric energy meters 19 to be scrapped; FIG2 is a schematic diagram of the structure of a turnover box 21 in an electric energy meter scrapping device provided in an embodiment of the present invention, Figure 2b Another structural schematic diagram of a turnover box in an electric energy meter scrapping device provided by an embodiment of the present invention; Figure 2c A schematic diagram of a turnover box loaded with an electric energy meter to be scrapped in an electric energy meter scrapping device provided by an embodiment of the present invention; Figure 2a ,picture Figure 2b , Figure 2c As shown, the turnover box 21 is a box with an open top, and has a certain amount of accommodation space inside, and multiple electric energy meters 19 to be scrapped can be placed side by side, for example, Figure 2a The turnover box shown is a single-phase electric energy meter turnover box, which can accommodate 12 electric energy meters to be scrapped; Figure 2b The turnover box shown is a three-phase electric energy meter turnover box, which can accommodate 4 electric energy meters to be scrapped. Of course, in practical applications, turnover boxes 21 of other specifications can also be used, and the embodiment of the present invention is not limited here.

[0020] The chassis 13 is a common box structure of equipment, the difference is that the chassis 13 in the embodiment of the present invention has an opening on both sides, the opening on the left side can be used as an entrance 1301, and the opening on the right side can be used as an exit 1302. The strip conveyor belt 102 passes through the entrance 1301 and the exit 1302 of the chassis 13, and then can transport the meter box into the chassis 13. The laser 15 located in the chassis 13 irradiates the laser beam onto the electric energy meter; The exhaust assembly 17 is located inside the chassis 13 , and the air inlet of the exhaust assembly 17 is arranged below the portion of the conveyor belt 102 located inside the chassis 13 .

[0021] Furthermore, in order to facilitate loading and unloading, the stacker 100 includes: a conveyor belt 102, a stacker 101, wherein: The conveyor belt 102 passes through an inlet 1301 and an outlet 1302 located on opposite sides of the chassis 13; The stacker 101 is located at one side of the conveyor belt 102 and is used to place the turnover box 21 on the conveyor belt 102 and remove the turnover box 21 containing the scrapped electric energy meter from the conveyor belt 102 .

[0022] Furthermore, Figure 3 A schematic diagram of the top structure of an electric energy meter scrapping device provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, in order to improve work efficiency and reduce hardware costs, the conveyor belt 102 is annular as a whole, and the stacker 101 is located on one side of the end of the conveyor belt 102; the scrapping device 200 provided in the embodiment of the present invention is located on one side of the conveyor belt 102, that is, this side of the conveyor belt 102 runs through the entrance 1301 and the exit 1302 on both sides of the scrapping device 200, so that only one stacker is used to realize the two functions of moving the meter box onto the conveyor belt 102 and moving the meter box off the conveyor belt 102, that is, one workstation realizes two different processes, reduces the number of stackers or manipulators used, and thereby reduces the overall hardware cost of the scrapping device 200.

[0023] Furthermore, a camera 23 is also provided in the chassis 13, and the shooting range of the camera 23 covers the length of the conveyor belt 102 in the chassis. The camera 23 continuously shoots, and images of the range of the conveyor belt 102 in the chassis at different times can be obtained, and then the image recognition algorithm is used to identify the position and number of the electric energy meters 19 to be scrapped in the turnover box 21, and then the six-degree-of-freedom slide rail 2903 is adjusted according to the position of the electric energy meters 19 to be scrapped, and then the laser 15 is adjusted to the position directly above the electric energy meters 19 to be scrapped. When the electric energy meters 19 to be scrapped are directly below the laser 15, the exhaust component 17 is then started, and then the laser 15 is started for irradiation, and the laser 15 irradiates each electric energy meter 19 to be scrapped for a set time. Then, by analogy, the above operations are performed on each electric energy meter 19 to be scrapped, and then each electric energy meter 19 to be scrapped in the turnover box 21 can be laser-drilled.

[0024] In actual applications, the six-degree-of-freedom slide rail 2903 includes: a horizontal slide rail 2902, a longitudinal slide rail 2901, and a vertical telescopic mechanism 2903, wherein the laser 15 and the camera 23 are both installed on the vertical telescopic mechanism 2903, which can realize the synchronous movement and lifting of the laser 15 and the camera 23, thereby reducing the difficulty of positioning the scrapped electricity meter 19.

[0025] The transverse slide rail 2902 extends in the direction from the entrance 1301 to the exit 1302, and can be slidably installed on the longitudinal slide rail 2901. The transverse slide rail 2902 can slide along the longitudinal slide rail 2901 in the direction perpendicular to the entrance 1301 to the exit 1302; the vertical telescopic mechanism 2903 can slide along the transverse slide rail 2902 in the direction from the entrance 1301 to the exit 1302.

[0026] Furthermore, in order to reduce the noise during operation of the device, a fireproof and sound-absorbing cotton 25, such as graphite felt, is provided on the inner surface of the chassis 13.

[0027] In order to reduce the impact of smoke generated during laser beam irradiation on the environment, the exhaust component 17 is also connected to a filter device 18 to filter the smoke in the air exhausted by the exhaust component 17, thereby eliminating PM2.5 and harmful gas components contained in the smoke.

[0028] In practical applications, the exhaust assembly 17 includes an air suction port 1701, an exhaust duct 1702, and an exhaust fan 1703 which are connected in sequence; the air suction port 1701 is an inverted cone structure with an upper opening, thereby expanding the air suction area and improving the smoke exhaust effect; The exhaust duct 1702 is used to transport the air sucked in by the air inlet 1701 to the filter device 18 under the action of the exhaust fan 1703.

[0029] Furthermore, in order to improve the fire extinguishing effect, there is an air supply assembly 27 on the top of the chassis 13 of the scrapping device 200. The air supply assembly 27 includes an air supply port 2701, an air supply duct 2702, and an air supply fan 2703 which are connected in sequence; the air supply port 2701 is an inverted cone structure with an upper opening, thereby expanding the air supply area and improving the air supply effect; The air supply duct 1702 is used to transport the air delivered by the air supply port 2701 into the chassis 13 under the action of the air supply fan 2703.

[0030] In practical applications, the air supply component 27 can prevent the accumulation of heat generated by the laser 15 during irradiation by increasing the air supply flow rate, thereby preventing fire. At the same time, the large air supply flow rate can also fully dilute the concentration of smoke generated by the laser 15 during irradiation, thereby preventing the smoke from damaging the laser beam and improving the scrapping effect.

[0031] Furthermore, in order to further improve the fire extinguishing effect, the air supply fan 2703 is also connected to the inert gas storage tank. At this time, the inert gas is used as a fire extinguishing gas. The air supply fan 2703 extracts the inert gas from the inert gas storage tank and then delivers the inert gas into the chassis 13. Similarly, the air supply component 27 can avoid the accumulation of heat generated by the laser 15 during irradiation by increasing the air supply flow rate. At the same time, the inert gas also has a fire extinguishing effect, isolating the combustion aid, thereby achieving a better fire extinguishing and fire prevention effect.

[0032] Furthermore, to prevent the gas containing smoke in the chassis 13 from leaking into the workshop, the air supply volume (including the air supplied and the inert gas) of the air supply fan 2703 is smaller than the exhaust volume of the exhaust assembly 17. For example, the chassis 13 can be roughly maintained in a slightly negative pressure environment, and the air in the workshop can enter the chassis 13 through the inlet 1301 and the outlet 1302 on the opposite sides of the chassis 13, thereby forming a barrier to prevent the leakage of smoke.

[0033] Corresponding to the present invention Figure 1 The present invention also provides a method for scrapping an electric energy meter. Figure 5 A schematic diagram of a process for scrapping an electric energy meter provided by an embodiment of the present invention, such as Figure 5 As shown, the method includes: S101: Place the turnover box 21 containing the electric energy meter 19 to be scrapped on the left end of the conveyor belt 102; then start the device, the conveyor belt 102 starts to rotate, and the turnover box 21 is transported to the right.

[0034] S102: The conveyor belt 102 conveys the turnover box 21 into the chassis 13; For example, after the conveyor belt 102 conveys the turnover box 21 to be completely inside the chassis 13 and within the effective irradiation range of the laser 15, the conveyor belt 102 stops moving. Of course, after the irradiation of the scrapped energy meter 19 is completed, the conveyor belt 102 resumes moving and conveys the turnover box 21 out.

[0035] Furthermore, for the purpose of recording, a first photo of the electric energy meter 19 to be scrapped is taken before the laser 15 irradiates the electric energy meter 19 to be scrapped, and the first photo includes a barcode of the electric energy meter 19 to be scrapped and a front image of the electric energy meter 19 to be scrapped.

[0036] S103: The laser 15 sequentially irradiates the target area on the surface of each of the scrapped electric energy meters 19 with a laser beam, and continuously irradiates the target area of ​​each of the scrapped electric energy meters 19 for a set time period; The laser 15 starts to work, irradiating the target area of ​​each scrapped electric energy meter 19 for 5 seconds in turn, and then punching holes in the dial and circuit board of the scrapped electric energy meter 19. It should be emphasized that when irradiating the target area, the laser beam will penetrate the shell of the scrapped electric energy meter 19 and the chip area of ​​the circuit board inside the shell, and then the laser will irradiate the chip position to achieve the goal of scrapping the electric energy meter; and then punch holes in the circuit board. In actual applications, the laser beam can irradiate the scrapped electric energy meter 19 downward in the vertical direction.

[0037] Furthermore, in order to avoid the influence of smoke generated during laser irradiation on the laser, when the laser 15 irradiates the electric energy meter 19 to be scrapped, the exhaust component 17 is started. Since the exhaust component 17 is located below the conveyor belt 102, the smoke will be sucked under the conveyor belt 102 at this time, thereby avoiding the absorption of the laser beam by the smoke and improving the scrapping effect.

[0038] Furthermore, in order to avoid fire caused by high temperature generated during laser irradiation, when the laser 15 irradiates the scrapped electricity meter 19, the air supply component is started. The air supply component is located inside the chassis 13 and is arranged above the conveyor belt 102. The air supply component is used to inject fire extinguishing gas into the chassis 13.

[0039] S104: After all the electric energy meters 19 to be scrapped are irradiated, the turnover boxes 21 are transported out of the chassis 13 .

[0040] S105: After the laser 15 irradiates the electric energy meter 19 to be scrapped, a second photo of the electric energy meter 19 to be scrapped is taken. The second photo is a front photo of the electric energy meter 19 to be scrapped after being irradiated by the laser.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
