Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meter disassembly, and in particular to an electric energy meter disassembly system. Background Art

[0002] With the transformation and upgrading of the global energy structure, the update and iteration speed of electricity meters, as the core metering equipment of smart grids, has been significantly accelerated, resulting in a large number of obsolete electricity meters that need to be disposed of urgently.

[0003] The current industry relies heavily on traditional manual disassembly, primarily in small, decentralized centers. This model presents significant challenges, including low efficiency, high labor intensity, crude workmanship, and high environmental risks. This makes it difficult to meet the demands for large-scale, refined, and intelligent disassembly, leading to high resource recovery costs and severely restricting the value of resource recovery and the sustainable development of the industry. Furthermore, the crude manual disassembly process and ambiguity in manual sorting result in low recovery rates for materials such as metals, plastics, and circuit boards. Furthermore, the lack of precision in disassembling the complex internal structures of electricity meters can easily damage components and cause material contamination, necessitating secondary screening and further limiting resource recycling efficiency. Furthermore, the lack of effective control over hazardous materials (such as lead seal debris and residual electronic components) during the disassembly process can easily lead to dust dispersion and environmental pollution. Summary of the Invention

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

[0005] The present invention is achieved through the following technical solutions: an electric energy meter disassembly system, comprising a screening system, a feeding system, a conveying system and a disassembly system, wherein the conveying system comprises a first conveying line and a second conveying line;

[0006] The loading system includes a loading conveyor line, which receives trays loaded with electric energy meters from the screening system and is provided with a second transfer mechanism for transferring the electric energy meters one by one to the first conveyor line;

On the first conveyor line, the labels and seals of the electric energy meter are disassembled and recycled, the upper cover is separated from the base, the base is separated from the circuit board, and the base components are disassembled and recycled. On the second conveyor line, the communication box is disassembled and recycled, the nameplate cover is disassembled and recycled, and the display window and flip cover are disassembled and recycled.

[0008] The upper cover separation area transfers the separated energy meter upper cover to the communication box disassembly area through the third transfer mechanism, and the circuit board removal area is connected to the circuit board disassembly area for disassembling and recycling the separated energy meter circuit board through the fourth transfer mechanism.

DETAILED DESCRIPTION

[0037] like Figures 1 to 26 As shown, in this embodiment, a power meter disassembly system is mainly disclosed, which is particularly suitable for the disassembly and parts recycling of single-phase smart power meters. The power meter is a standard device well known to those skilled in the art. Its structure includes a base and a top cover fastened by a first screw. The base and the top cover are embedded with embedded nails. The seams on both sides of the base and the top cover are covered with labels and connected with lead seals. The base is threaded with a second screw for wiring. The base is connected to a circuit board via a third screw. A hanging plate is clamped on the bottom of the base for easy hanging. The circuit board is connected to a terminal block via a fourth screw. The terminal block is provided with copper pillars connected to the wires. A communication box is provided in the top cover, and its surface is buckled by a nameplate cover hinged to the top cover. The top cover is also provided with a display window and a flip cover covering the terminal block. The disassembly system disassembles each component of the power meter in sequence, and mainly includes a screening system 1, a feeding system 2, a conveying system 20 and a disassembly system.

[0038] Among them, such as Figure 2As shown, the screening system 1 includes a belt conveyor 11 for loading discarded electricity meters, a double-track conveyor roller 12 is mounted above the belt conveyor 11, and a destacking mechanism 13 is provided at one end of the double-track conveyor roller 12 for splitting the stacked empty pallets into single empty pallets. A robotic arm 14 is provided on one side of the belt conveyor 11. The robotic arm 14 is used to sort and transfer the electricity meters from the belt conveyor 11 to the single empty pallets conveyed by the double-track conveyor roller 12. A palletizing mechanism 15 is provided at the other end of the double-track conveyor roller 12 for palletizing pallets fully loaded with electricity meters. The palletizing mechanism 15 is connected to a first transfer mechanism 16 for transporting the pallets fully loaded with electricity meters and palletized to the loading conveyor line 21. Specifically, the double-track conveyor roller 12 is composed of two parallel roller conveyor lines, and the robotic arm 14 is arranged between the two roller conveyor lines. Both the depalletizing mechanism 13 and the palletizing mechanism 15 consist of a lifting cylinder mounted on a half-frame for telescopically lifting the pallet horizontally and a lifting cylinder for vertically lifting the pallet. The first transfer mechanism 16 includes a transverse slide rail equipped with a longitudinal platform. The operator places the energy meters one by one on the belt conveyor 11 with the covers facing upward. The belt conveyor 11 then transports the energy meters to the bottom of the robotic arm 14. The robotic arm 14 uses an existing, mature visual recognition system to take a photo of the energy meters and confirm their model. Based on the information, the robotic arm 14 uses a pneumatic gripper to grasp the energy meters and place them on the corresponding empty pallet. When the pallet is filled with energy meters, the corresponding roller conveyor line starts to transport the pallet to the position of the palletizing mechanism 15, while the corresponding roller conveyor line simultaneously delivers empty pallets. At the position of the palletizing mechanism 15, the lifting cylinder is inflated and lifted, lifting the pallets up and stacking them layer by layer. After the pallets are stacked four layers high, they are transported to the longitudinal platform, which moves horizontally along the transverse slide rail to align the pallets with the workstation of the loading system 2.

[0039] like Figure 3 As shown, the feeding system 2 includes a feeding conveyor line 21, one end of which receives the pallet fully loaded with electricity meters from the screening system 1, and a second transfer mechanism 22 is provided in the middle of the feeding conveyor line 21 for transferring the electricity meters to the starting end of the first conveyor line 201. Specifically, the feeding system 2 also includes a temporary storage area 23, a destacking area 24, a pallet positioning area 25 and a pallet recovery area 26 sequentially arranged 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 fully loaded with electricity meters and stacked to the destacking area 24 for destacking, transports the pallets fully loaded with electricity meters after destacking to the pallet positioning area 25, where the second transfer mechanism 22 clamps and transfers the electricity meters, and transports the empty pallets to the pallet recovery area 26 for palletizing and recovery.

[0040] like Figure 1 and Figure 4As shown, the conveying system 20 includes a first conveyor line 201 and a second conveyor line 202. The first conveyor line 201 is used for disassembling the entire electricity meter and removing the base, while the second conveyor line 202 is used for removing the upper cover. Both the first conveyor line 201 and the second conveyor line 202 are fork conveyor lines, including a horizontal slide for supporting the electricity meter. A horizontal push mechanism is provided below the horizontal slide. A vertical telescopic mechanism is provided at the output end of the horizontal push mechanism. A fork is provided at the output end of the vertical telescopic mechanism. The horizontal push mechanism drives the vertical telescopic mechanism and the fork to move back and forth linearly along the extension direction of the horizontal slide. Combined with the lifting movement of the vertical telescopic mechanism, intermittent cyclic reciprocating motion is achieved, and the fork is used to push the electricity meter forward to the subsequent workstation. The electricity meter is accurately delivered to the bottom of each workstation through the conveying system 20. Each workstation is equipped with a positioning assembly 205 for limiting the position of the electricity meter. The positioning assembly 205 includes a positioning cylinder provided on a positioning bracket. The positioning cylinder is connected to a clamping claw to clamp the electricity meter.

[0041] like Figure 1 As shown, the disassembly system includes an appearance disassembly area 3, an upper cover separation area 4, a circuit board removal area 5 and a base disassembly area 6 which are sequentially arranged on the first conveyor line 201, and a communication box disassembly area 7, a nameplate cover disassembly area 8 and an upper cover disassembly area 9 which are sequentially arranged on the second conveyor line 202. On the first conveyor line 201, the labels and lead seals of the electric energy meter are disassembled and recycled, the upper cover is separated from the base, the base is separated from the circuit board, and the base components are disassembled and recycled. On the second conveyor line 202, the communication box is disassembled and recycled, the nameplate cover is disassembled and recycled, and the display window and flip cover are disassembled and recycled. The upper cover separation area 4 transfers the separated upper cover of the electric energy meter to the communication box disassembly area 7 through the third transmission mechanism 203. The circuit board removal area 5 is connected to the circuit board disassembly area 10 for disassembling and recycling the separated electric energy meter circuit board through the fourth transmission mechanism 204. Specifically, on the first conveyor line 201, the meter's label and seal are removed, the upper cover is separated from the base, the wiring screws are removed, the circuit board is removed, the base is nailed, and the hanging plate is removed. On the second conveyor line 202, the separated upper cover is removed, followed by the communication box, nameplate cover, display window and flip cover, and upper cover nailing. On the circuit board, the circuit board removal area 10 sequentially separates the terminal blocks, removes the copper pillars, and removes the terminal block nailing. This enables the precise and simultaneous disassembly of multiple components of the meter, improving disassembly efficiency and resource recovery.

[0042] Furthermore, in specific implementation, Figure 5As shown, in the above-mentioned appearance disassembly area 3 provided in the embodiment of the present invention, a label cutting mechanism 31 and a lead seal removal mechanism 32 are sequentially arranged along the first conveyor line 201. The label cutting mechanism 31 includes a pneumatic finger arranged on a linear actuator, and the end of the finger rod of the pneumatic finger is rotatably connected to a cutting wheel. First, the linear actuator drives the pneumatic finger to extend outward and approach the electricity meter. Then, the finger rods are driven by the pneumatic finger to approach each other to form an encirclement effect on both sides of the electricity meter. The blade of the cutting wheel is horizontally aligned with the seam between the upper cover and the base of the limited electricity meter. Discarded electricity meters usually meet national standards, so the seam width between the upper cover and the base is basically the same on each electricity meter. This saves the time of adjusting the cutting wheel height to match the seam height. The blade of the cutting wheel is inserted into the seam, and then the linear actuator continues to drive the pneumatic finger closer to the electricity meter, driving the cutting wheel to cut the label along the seam. The seal removal mechanism 32 comprises a milling cutter and a three-axis adjuster for adjusting the cutter's spatial position. The three-axis adjuster employs a conventional structure known in the art. Its specific composition and operating principle are well known to those skilled in the art and will not be further described. It primarily functions to achieve movement in the X, Y, and Z axes, driving the milling cutter to sequentially remove the seals on the electricity meter. Furthermore, a dust collector is installed on one side of the milling cutter to absorb debris and reduce environmental pollution.

[0043] Furthermore, in a specific implementation, the upper cover separation area 4 provided in the embodiment of the present invention is provided with a first screw removal mechanism 41 and a first separation mechanism 42 in sequence;

[0044] like Figure 6 As shown, the first screw removal mechanism 41 includes a first electric screwdriver 410 for loosening the screws connecting the upper cover and the base of the electric energy meter and a first three-axis adjuster 411 for changing the spatial position of the first electric screwdriver 410; specifically, the electric energy meter is transported to the bottom of the workstation where the first screw removal mechanism 41 is located through the first conveyor line 201, one end of the base is limited by the positioning assembly 205, and the other end is abutted and limited by the abutment mechanism 206 inserted into the gap between the base and the hanging plate, and at the same time, the upper cover of the electric energy meter is limited by the vacuum suction cup, and the first three-axis adjuster 411 drives the first electric screwdriver 410 to realize movement in the three directions of X-axis, Y-axis and Z-axis, and loosens the first screws in sequence to release the connection between the upper cover and the base. At this time, the loosened first screw is limited in the nail hole of the upper cover and does not slide down;

[0045] like Figure 7 and Figure 8As shown, the first separation mechanism 42 includes a pulling cylinder 421 and a first pneumatic clamping 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 transmission mechanism 203. The first pneumatic clamping finger 422 contacts both sides of the upper cover of the electric energy meter to clamp the upper cover of the electric energy meter. Specifically, the electric energy meter is at the workstation where the first separation mechanism 42 is located, and its base is also restricted by the positioning assembly 205 and the abutment mechanism 206. The upper cover is clamped by the first pneumatic clamping finger 422, and the upper cover and the base are separated by pulling up with the pulling cylinder 421. Then, the upper cover part is placed at the starting end of the second conveyor line 202 by the third transmission mechanism 203, and the base part is transported to the next workstation via the first conveyor line 201.

[0046] Furthermore, in specific implementation, Figures 9 and 10 As shown, the circuit board removal area 5 provided in the embodiment of the present invention is provided with a second screw removal mechanism 51, a third screw removal mechanism 52 and a second separation mechanism 53 in sequence;

[0047] The second screw removal mechanism 51 includes a second electric screwdriver 511 for loosening the base wiring screws, a second three-axis adjuster 512 for changing the spatial position of the second electric screwdriver 511, and a first nail suction mechanism 54 for sucking and recovering the loosened base wiring screws. Specifically, the second three-axis adjuster 512 drives the second electric screwdriver 511 to realize movement in the three directions of X-axis, Y-axis, and Z-axis, and loosens the second screw on the base in turn. After the second screw is loosened, the base is transported backward by the first conveyor line 201 and sucks the base wiring screws through the first nail suction mechanism 54. The first nail suction mechanism 54 includes a nail suction cylinder 541, and the piston rod of the nail suction cylinder 541 is connected to a suction head 542 connected to a suction pump. In addition, two sets of the second screw removal mechanism 51 are arranged along the first conveyor line 201, and the two sets of the second screw removal mechanism 51 operate simultaneously, thereby improving the disassembly efficiency;

[0048] like Figure 11 As shown, the third screw removal mechanism 52 includes a third electric screwdriver 521 for loosening the circuit board connecting screws, a third three-axis adjuster 522 for changing the spatial position of the third electric screwdriver 521, and a second nail suction mechanism for sucking and recovering the loosened circuit board connecting screws; specifically, the third three-axis adjuster 522 drives the third electric screwdriver 521 to realize movement in the three directions of X-axis, Y-axis, and Z-axis, loosening the third screw on the circuit board in turn, and releasing the connection between the circuit board and the base. After the third screw is loosened, the base is transported backward by the first conveyor line 201 and absorbs the circuit board screw through the second nail suction mechanism. The structure of the second nail suction mechanism is the same as that of the first nail suction mechanism 54.

[0049] like 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.

[0050] 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.

[0051] 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;

[0052] like Figure 14 and Figure 15As shown, the base embedded nail removal mechanism 61 includes a first punching mechanism 610, a second clamping mechanism 611 and a second transverse frame 612. The first punching mechanism 610 includes a punching gantry 613 and a first horizontal two-axis adjuster 614. The punching gantry 613 is provided with a first punching cylinder 615 for punching embedded nails in the base. The first horizontal two-axis adjuster 614 is provided with a base carrier 616 that can be horizontally moved for limiting the base of the electric energy meter. A base embedded nail recovery groove is provided below the base carrier 616. The second clamping mechanism 611 is horizontally connected to the second transverse frame 612. The horizontal sliding connection is used to load and unload materials between the first conveyor line 201 and the base platform 616. The second clamping mechanism 611 includes a second vertical cylinder 617. The piston rod of the second vertical cylinder 617 is connected to the second suction cup 618 for vacuum adsorption of the base of the electricity meter. Specifically, the first horizontal two-axis adjuster 614 includes a first adjustment cylinder that is slidably connected to the base platform 616 for adjusting the horizontal longitudinal position of the base platform 616, and a second adjustment cylinder that is slidably connected to the mounting plate carrying the first adjustment cylinder for adjusting the horizontal transverse position of the base platform 616. Through the cooperation of the second clamping mechanism 611 and the second transverse frame 612, the flipped base is transferred from the first conveyor line 201 to the upper limit of the adjustment platform, and the position of the first horizontal two-axis adjuster 614 relative to the stamping gantry 613 is changed by adjusting the position of the horizontal plane, and the embedded nails in the base are flushed out one by one, and the embedded nails are collected by the base embedded nail recovery trough to the base embedded nail recovery box.

[0053] like Figure 16 As 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 electric energy meter base. The second mounting frame 621 is provided with a hanging plate recovery groove 623 and a pulling cylinder 624 for pulling upward and separating the electric energy meter base hanging plate. Specifically, the base after punching and embedding nails is moved by the second clamping mechanism 611 along the second transverse frame 612, and is transferred back to the first conveyor line 201, and is transported to the workstation where the hanging plate disassembly mechanism 62 is located via the first conveyor line 201. The end of the base away from the hanging plate installation position is clamped and fixed by the base limiting mechanism 622, while the end of the base where the hanging plate is installed is close to the starting top of the hanging plate slide groove. The output shaft end of the pulling cylinder 624 acts on the hanging plate to pull the hanging plate upward. When the base loses its clamping effect on the hanging plate, the hanging plate is separated from the base and collected in the hanging plate recovery box through the hanging plate recovery groove 623.

[0054] Furthermore, in a specific implementation, the circuit board disassembly area 10 provided in the embodiment of the present invention is provided with a third separation mechanism and a copper pillar disassembly mechanism 102;

[0055] like Figure 17As shown, the third separation mechanism includes a third mounting bracket, a fourth three-axis adjuster for changing the spatial position of the third mounting bracket, and a circuit board carrier 1011 for limiting the placement of the circuit board. The third mounting bracket is equipped with a milling cutter for milling the solder joints on the circuit board and a fourth electric screwdriver for loosening the terminal block screws.
