Description

Technical Field

[0001] The present invention relates to the technical field of electricity meter disassembly, and more particularly, to an electricity meter disassembly system. Background Art

[0002] With the transformation and upgrading of the global energy structure, the electricity meter, as the core metering device of the smart grid, has significantly accelerated its renewal and iteration speed, resulting in a large number of waste electricity meters waiting to be processed.

[0003] Currently, the industry generally relies on traditional manual disassembly. The existing disassembly mode mainly consists of scattered small-scale disassembly centers, which have prominent problems such as low efficiency, high labor intensity, rough technology, and high environmental protection risks. It is difficult to meet the large-scale, refined, and intelligent disassembly requirements, resulting in high resource recovery costs, seriously restricting the resource recovery value and the sustainable development of the industry. At the same time, the rough manual disassembly process and the ambiguity of manual classification lead to low recovery rates of materials such as metal, plastic, and circuit boards. In addition, the insufficient disassembly accuracy of the complex internal structure of the electricity meter is likely to cause damage to components or material mixing, requiring secondary screening and processing, further restricting the resource recycling efficiency. More seriously, there is a lack of effective control over harmful substances (such as lead seal debris and electronic component residues) during the disassembly process, which is likely to cause dust diffusion and environmental pollution. Summary of the Invention

[0004] The purpose of the present invention is to provide an electricity meter disassembly system, which solves the problems of low disassembly efficiency, disassembly granularity, and resource recovery rate of existing electricity meters.

[0005] The present invention is achieved through the following technical solutions: An electricity meter disassembly system includes a screening system, a feeding system, a conveying system, and a disassembly system. The conveying system includes a first conveyor line and a second conveyor line; The feeding system includes a feeding conveyor line. The feeding conveyor line receives the tray full of electricity meters from the screening system, and the feeding conveyor line is provided with a second transfer mechanism for transferring the electricity meters to the first conveyor line one by one; The disassembly system includes an appearance disassembly area, an upper cover separation area, a circuit board extraction area, and a base disassembly area sequentially arranged on the first conveyor line, and a communication box disassembly area, a label cover disassembly area, and an upper cover disassembly area sequentially arranged on the second conveyor line. The electricity meter is sequentially subjected to label and lead seal disassembly and recovery, upper cover and base separation, base and circuit board separation, and base component disassembly and recovery on the first conveyor line, and the electricity meter is sequentially subjected to communication box disassembly and recovery, label cover disassembly and recovery, and display window and flip cover disassembly and recovery on the second conveyor line; The upper cover separation area transfers the separated upper cover of the electricity meter to the communication box disassembly area through a third transfer mechanism, and the circuit board extraction area is connected to a circuit board disassembly area for disassembly and recovery of the separated electricity meter circuit board through a fourth transfer mechanism.

[0006] The present invention has at least the following advantages and beneficial effects: By setting up a screening system, a feeding system, a conveying system, and a disassembly system, the electric energy meter is successively subjected to label and lead seal disassembly and recycling, upper cover and base separation, base and circuit board separation, and base component disassembly and recycling on the first conveyor line, and the electric energy meter is successively subjected to communication box disassembly and recycling, nameplate cover disassembly and recycling, and display window and flip cover disassembly and recycling on the second conveyor line.

[0034] As Figures 1 to 26 shown, in this embodiment, a watt-hour meter disassembly system is mainly disclosed, which is particularly applicable to the disassembly and component recovery of single-phase smart watt-hour meters. The watt-hour meter is a standard device well-known to those skilled in the art, and its structure includes a base and an upper cover fastened by the first screw. Buried nails are embedded in both the base and the upper cover. Labels are covered at the joints on both sides of the base and the upper cover, and lead seals are connected. The base is threadedly connected with a second screw for wiring. A circuit board is connected to the base by a third screw. A hanging plate for easy hanging is clamped at the outer bottom of the base. The circuit board is connected to a terminal block by a fourth screw, and copper columns for connecting wires are provided in the terminal block. A communication box is arranged in the upper cover, and its surface is covered by a sign cover hinged to the upper cover. The upper cover also has a display window and a flip cover covering the terminal block. This disassembly system disassembles each component of the watt-hour meter in sequence, mainly including a screening system 1, a feeding system 2, a conveying system 20, and a disassembly system.

[0035] Among them, as Figure 2As shown, the screening system 1 includes a belt conveyor 11 for feeding waste electric energy meters. Above the belt conveyor 11, there is a double-track conveying roller 12. At one end of the double-track conveying roller 12, there is a palletizing mechanism 13 for splitting stacked empty pallets into single empty pallets. On one side of the belt conveyor 11, there is a robotic arm 14, which is used to sort and transfer the electric energy meters from the belt conveyor 11 to a single empty pallet conveyed by the double-track conveying roller 12. At the other end of the double-track conveying roller 12, there is a palletizing mechanism 15 for palletizing the pallets full of electric energy meters. The palletizing mechanism 15 is connected to a first transfer mechanism 16 for transporting the pallet full of and palletized electric energy meters to the feeding conveyor line 21. Specifically, the double-track conveying roller 12 consists of two parallel roller conveyor lines, and the robotic arm 14 is arranged between the two roller conveyor lines. Both the palletizing mechanism 13 and the palletizing mechanism 15 are composed of a lifting cylinder arranged on a semi-frame for horizontally stretching and lifting the pallet and a jacking cylinder for vertically jacking up the pallet. The first transfer mechanism 16 includes a transverse sliding rail, and a longitudinal moving platform is arranged on the transverse sliding rail. The operator places the electric energy meters one by one on the belt conveyor 11 with the upper cover facing up. The belt conveyor 11 transports the electric energy meters to the lower part of the robotic arm 14. The robotic arm 14 takes pictures of the electric energy meters through an existing mature vision judgment system and confirms the model of the electric energy meters. The robotic arm 14 uses a pneumatic gripper to pick up the electric energy meters according to the information and places the electric energy meters into the corresponding empty pallets. When the pallet is full of electric energy meters, the corresponding roller conveyor line starts to transport the pallet to the position of the palletizing mechanism 15, and at the same time, the corresponding roller conveyor line sends an empty pallet over. At the position of the palletizing mechanism 15, the jacking cylinder is inflated to jack up the pallet, and the pallets are stacked layer by layer. After the pallet is stacked four layers, the pallet is transported to the longitudinal moving platform, and the longitudinal moving platform translates along the transverse sliding rail to align the pallet with the working station of the feeding system 2.

[0036] As Figure 3 shown, the feeding system 2 includes a feeding conveyor line 21. One end of the feeding conveyor line 21 receives the pallet full of electric energy meters from the screening system 1. In the middle of the feeding conveyor line 21, there is a second transfer mechanism 22 for transferring the electric energy meters to the starting end of the first conveyor line 201. Specifically, the feeding system 2 further includes a temporary storage area 23, a palletizing area 24, a pallet positioning area 25, and a pallet recycling area 26 arranged in sequence on the feeding conveyor line 21. The temporary storage area 23 is connected to the first transfer mechanism 16. The feeding conveyor line 21 sequentially transports the pallets full of and stacked electric energy meters to the palletizing area 24 for palletizing, transports the pallets full of electric energy meters after palletizing to the pallet positioning area 25, and the second transfer mechanism 22 picks up and transfers the electric energy meters, and transports the empty pallets to the pallet recycling area 26 for palletizing and recycling.

[0037] As Figure 1 and Figure 4As shown, the conveying system 20 includes a first conveying line 201 and a second conveying line 202. The first conveying line 201 is used for the overall disassembly of the electricity meter and the disassembly of the base, and the second conveying line 202 is used for the disassembly of the upper cover. Both the first conveying line 201 and the second conveying line 202 adopt a fork conveying line, which includes a horizontal slideway for supporting the electricity meter. A horizontal pushing mechanism is arranged below the horizontal slideway, and a vertical telescopic mechanism is arranged at the output end of the horizontal pushing mechanism. A fork is arranged at the output end of the vertical telescopic mechanism. The horizontal pushing mechanism drives the vertical telescopic mechanism and the fork to perform reciprocating linear motion along the extension direction of the horizontal slideway. Combining with the lifting motion of the vertical telescopic mechanism, an intermittent cyclic reciprocating motion is realized, and the electricity meter is pushed forward to the subsequent workstations by the fork. The electricity meter is accurately transferred to the lower part of each workstation through the conveying system 20. A positioning component 205 for limiting the electricity meter is arranged at each workstation. The positioning component 205 includes a positioning cylinder arranged on a positioning bracket, and the positioning cylinder is connected with a claw for clamping the electricity meter.

[0038] As Figure 1 shown, the disassembly system includes an appearance disassembly area 3, an upper cover separation area 4, a circuit board extraction area 5, and a base disassembly area 6 sequentially arranged on the first conveying line 201, and a communication box disassembly area 7, a label cover disassembly area 8, and an upper cover disassembly area 9 sequentially arranged on the second conveying line 202. On the first conveying line 201, the label and lead seal of the electricity meter are disassembled and recycled, the upper cover and the base are separated, the base and the circuit board are separated, and the base components are disassembled and recycled. On the second conveying line 202, the communication box of the electricity meter is disassembled and recycled, the label cover is disassembled and recycled, and the display window and the flip cover are disassembled and recycled. The separated upper cover of the electricity meter is transferred to the communication box disassembly area 7 by a third transfer mechanism 203 in the upper cover separation area 4. The circuit board extraction area 5 is connected with a circuit board disassembly area 10 for disassembling and recycling the separated circuit board of the electricity meter through a fourth transfer mechanism 204. Specifically, the electricity meter sequentially undergoes label and lead seal disassembly, upper cover and base separation, wiring screw disassembly, circuit board extraction, base buried nail and hanging plate disassembly on the first conveying line 201. The separated upper cover sequentially undergoes communication box disassembly, label cover disassembly, display window and flip cover disassembly, and upper cover buried nail disassembly on the second conveying line 202. The circuit board in the circuit board disassembly area 10 sequentially undergoes terminal block separation, copper column and terminal block buried nail disassembly. The refined synchronous disassembly of multiple components of the electricity meter is realized, improving the disassembly efficiency and resource recovery rate.

[0039] Furthermore, in specific implementation, as Figure 5As shown in the figure, a label cutting mechanism 31 and a lead seal removing mechanism 32 are sequentially arranged along the first conveyor line 201 in the above-mentioned appearance disassembly area 3 provided in the embodiment of the present invention. The label cutting mechanism 31 includes a pneumatic finger arranged on a linear driver, and a cutting wheel is rotatably connected to the end of the finger rod of the pneumatic finger. First, the linear driver drives the pneumatic finger to extend out and approach the electricity meter. Then, the finger rods are driven by the pneumatic finger to approach each other to form an enclosing effect on both sides of the electricity meter. The cutting edge of the cutting wheel is horizontally aligned with the seam between the upper cover and the base of the limited electricity meter. Since the discarded electricity meters usually comply with national standards, the seam width between the upper cover and the base is basically the same on each electricity meter. In this way, the time for adjusting the height of the cutting wheel to match the seam height can be saved. The cutting edge of the cutting wheel is inserted into the seam. Then, the linear driver continues to drive the pneumatic finger to further approach the electricity meter, and the cutting wheel is driven along the seam to cut off the label. The lead seal removing mechanism 32 includes a milling cutter and a three-axis regulator for changing the spatial position of the milling cutter. The three-axis regulator adopts a conventional structure known in the art. The specific composition and working principle are well-known to those skilled in the art and will not be elaborated here. It is mainly used to achieve movements in the three directions of the X-axis, Y-axis, and Z-axis, and drive the milling cutter to remove the lead seals on the electricity meter in sequence. In addition, a dust suction device for sucking debris is arranged on one side of the milling cutter to reduce environmental pollution.

[0040] Further, in specific implementation, a first screw removing mechanism 41 and a first separating mechanism 42 are sequentially arranged in the above-mentioned upper cover separating area 4 provided in the embodiment of the present invention; As Figure 6 shown, the first screw removing mechanism 41 includes a first electric screwdriver 410 for loosening the connecting screws between the upper cover and the base of the electricity meter and a first three-axis regulator 411 for changing the spatial position of the first electric screwdriver 410; specifically, the electricity meter is conveyed to the lower part of the station where the first screw removing mechanism 41 is located through the first conveyor line 201. One end of the base is limited by the positioning component 205, and the other end is abutted and limited by the abutting mechanism 206 inserted into the gap between the base and the hanging plate. At the same time, the upper cover of the electricity meter is limited by a vacuum chuck. The first three-axis regulator 411 drives the first electric screwdriver 410 to achieve movements in the three directions of the X-axis, Y-axis, and Z-axis, and sequentially loosen the first screws to release the connection between the upper cover and the base. At this time, the loosened first screws are limited in the buried screw holes of the upper cover and do not slide down; As Figure 7 and Figure 8As shown in the figure, the first separation mechanism 42 includes a pulling cylinder 421 and a first pneumatic finger 422 connected to the piston rod of the pulling cylinder 421. The pulling cylinder 421 is horizontally and laterally slidably connected to the third transfer mechanism 203. The first pneumatic finger 422 contacts both sides of the upper cover of the electric energy meter for clamping the upper cover of the electric energy meter. Specifically, when the electric energy meter is at the station where the first separation mechanism 42 is located, its base is also restricted by the positioning component 205 and the abutting mechanism 206. By clamping the upper cover with the first pneumatic finger 422, the pulling cylinder 421 pulls up to separate the upper cover from the base, and then the upper cover part is placed at the starting end of the second conveying line 202 through the third transfer mechanism 203, while the base part is conveyed to the next station through the first conveying line 201.

[0041] Further, in specific implementation, as Figures 9 to 10 shown, in the above-mentioned circuit board extraction area 5 provided in the embodiment of the present invention, a second screw disassembly mechanism 51, a third screw disassembly mechanism 52 and a second separation mechanism 53 are sequentially provided; The second screw disassembly mechanism 51 includes a second electric screwdriver 511 for loosening the base wiring screws, a second three-axis regulator 512 for changing the spatial position of the second electric screwdriver 511, and a first screw suction mechanism 54 for sucking and recovering the loosened base wiring screws. Specifically, the second three-axis regulator 512 drives the second electric screwdriver 511 to move in three directions of the X-axis, Y-axis and Z-axis to sequentially loosen the second screws on the base. After the second screws are loosened, the base is conveyed backward by the first conveying line 201 and passes through the first screw suction mechanism 54 to suck the base wiring screws. The first screw suction mechanism 54 includes a screw suction cylinder 541, and the piston rod of the screw suction cylinder 541 is connected with a suction head 542 communicated with a suction pump. In addition, two sets of the second screw disassembly mechanism 51 are arranged along the first conveying line 201, and the two sets of the second screw disassembly mechanism 51 operate simultaneously, which improves the disassembly efficiency; As Figure 11 shown, the third screw disassembly mechanism 52 includes a third electric screwdriver 521 for loosening the circuit board connection screws, a third three-axis regulator 522 for changing the spatial position of the third electric screwdriver 521, and a second screw suction mechanism for sucking and recovering the loosened circuit board connection screws; specifically, the third three-axis regulator 522 drives the third electric screwdriver 521 to move in three directions of the X-axis, Y-axis and Z-axis to sequentially loosen the third screws on the circuit board, and release the connection between the circuit board and the base. After the third screws are loosened, the base is conveyed backward by the first conveying line 201 and passes through the second screw suction mechanism to suck the circuit board screws. The structure of the second screw suction mechanism is the same as that of the first screw suction mechanism 54.

[0042] As Figure 12As shown, the second separation mechanism 53 includes a first transverse frame 531, a first clamping mechanism 532, and an internal support structure 533 that abuts the inner wall of the power meter base to prop the power meter base open. The first clamping mechanism 532 is horizontally and laterally slidably connected to the first transverse frame 531 to transfer the removed circuit board to the fourth transfer mechanism 204. The first clamping mechanism 532 includes a first mounting frame 534. The first mounting frame 534 has two ends connected to oppositely arranged telescopic cylinders 535. The piston rods of the telescopic cylinders 535 are connected to clamping blocks that engage with the two ends of the circuit board to clamp the circuit board. A first suction cup 536 is provided below the first mounting frame 534 for vacuum adsorption of the circuit board. Specifically, the first transverse frame 531 is a single-axis gantry frame used to drive the horizontal movement of the first clamping mechanism 532. The internal support structure 533 includes a support rod, a first internal support cylinder that extends vertically to insert the support rod into the gap between the circuit board and the base, and a second internal support cylinder that extends outward toward the base to extend the base. This slightly deforms the base, facilitating the first gripping mechanism 532's grasping of the circuit board. After the base removes the circuit board, the base's contour returns to its original shape.

[0043] Furthermore, in specific implementation, Figure 13 As shown, the above-mentioned base disassembly area 6 and the upper cover disassembly area 9 provided in the embodiment of the present invention are both provided with a flipping mechanism 63, and the flipping mechanism 63 includes a flipping bracket 631, and a first vertical cylinder 632 is provided on the flipping bracket 631, and the piston rod of the first vertical cylinder 632 is connected to a second pneumatic clamping finger 633 for clamping the electric energy meter, and the clamping rod of the second pneumatic clamping finger 633 is rotatably connected to a clamping disc 634 that contacts the outside of the electric energy meter, and a first rotating cylinder 635 is provided on a clamping rod on one side of the second pneumatic clamping finger 633, and the output end of the first rotating cylinder 635 is connected to the clamping disc 634 through a pulley for driving the electric energy meter to flip 180°. Specifically, the flipping mechanism 63 of the base disassembly area 6 receives the base of the circuit board transported out by the first conveyor line 201, and the base is flipped and placed back on the first conveyor line 201 to facilitate subsequent nail embedding and punching of the base; and the flipping mechanism 63 of the upper cover disassembly area 9 receives the upper cover after the display window is stamped and flipped from the second conveyor line 202, and the upper cover is flipped and placed back on the second conveyor line 202 to facilitate subsequent nail embedding and punching of the upper cover.

[0044] Furthermore, in a specific implementation, the base disassembly area 6 provided in the embodiment of the present invention is provided with a base nail disassembly mechanism 61 and a hanging plate disassembly mechanism 62 in sequence; like Figure 14 and Figure 15As shown, the base buried nail disassembly mechanism 61 includes a first stamping mechanism 610, a second clamping mechanism 611 and a second transverse moving frame 612. The first stamping mechanism 610 includes a stamping gantry 613 and a first horizontal two-axis regulator 614. A first stamping cylinder 615 for stamping the buried nails in the base is arranged on the stamping gantry 613. A base carrier 616 which can move horizontally and is used to limit the position of the electricity meter base is arranged on the first horizontal two-axis regulator 614. A base buried nail recovery groove is arranged below the base carrier 616. The second clamping mechanism 611 is horizontally and transversely slidably connected to the second transverse moving frame 612 and is used for loading and unloading between the first conveyor line 201 and the base carrier 616. The second clamping mechanism 611 includes a second vertical cylinder 617, and the piston rod of the second vertical cylinder 617 is connected to a second suction cup 618 for vacuum-sucking the electricity meter base. Specifically, the first horizontal two-axis regulator 614 includes a first adjusting cylinder which is slidably connected to the base carrier 616 and is used to adjust the horizontal longitudinal position of the base carrier 616, and a second adjusting cylinder which is slidably connected to the mounting plate carrying the first adjusting cylinder and is used to adjust the horizontal transverse position of the base carrier 616. Through the cooperation of the second clamping mechanism 611 and the second transverse moving frame 612, the flipped base is transferred from the first conveyor line 201 to the regulating platform for limiting, and the position of the first horizontal two-axis regulator 614 relative to the stamping gantry 613 is changed by adjusting the position on the horizontal plane, and the buried nails in the base are punched out one by one and collected into the base buried nail recovery box by the base buried nail recovery groove; As Figure 16 shown, the hanging plate disassembly mechanism 62 includes a second mounting frame 621 and a base limiting mechanism 622 for fixing the position of the electricity meter base. A hanging plate recovery groove 623 and a pulling cylinder 624 for pulling up and separating the hanging plate of the electricity meter base are arranged on the second mounting frame 621. Specifically, after the buried nails are punched out, the base is moved along the second transverse moving frame 612 by the second clamping mechanism 611, re-transferred to the first conveyor line 201, and conveyed by the first conveyor line 201 to the station where the hanging plate disassembly mechanism 62 is located. One end of the base far from the hanging plate installation position is clamped and fixed up and down by the base limiting mechanism 622, and one end of the base where the hanging plate is installed is close to the starting top end of the hanging plate chute. The end of the output shaft of the pulling cylinder 624 acts on the hanging plate to pull up the hanging plate. When the base loses the clamping effect on the hanging plate, the hanging plate is separated from the base and collected into the hanging plate recovery box through the hanging plate recovery groove 623.

After the transverse cylinder 723 extends downward to make the fourth suction cup 724 adsorb on the communication box, the fourth suction cup 724 is lifted to pull out the communication box, and then the third transverse frame 721 moves back and puts the communication box into the communication box recovery groove 722 and slides into the communication box recovery box; As Figure 21 , Figure 22 shown, a fourth transverse frame 81 and a second connecting frame 82 are successively provided in the label cover disassembly area 8.
