Description

Technical Field

[0001] This invention relates to the field of electricity meter disposal, and more particularly to an electricity meter disposal device and system. Background Technology

[0002] As components in the power system used to measure electricity consumption, electricity meters must be scrapped at the end of their lifespan. Currently, the industry commonly uses physical destruction methods to irreversibly damage scrapped electricity meters, with drilling being one of the most frequently used techniques. Traditional electricity meter scrapping drilling mechanisms typically employ a fixed drilling rig structure, meaning the drill bit is positioned in a fixed location. The electricity meter is manually moved to the drilling position, and the drill is controlled to drill downwards to complete the scrapping process. Existing technology has the following significant drawbacks: when drilling multiple electricity meters, multiple process control steps are usually required to ensure that the meter positions are independent and fixed, and that the meter loading direction is aligned precisely with the positions of multiple fixed drill bits to achieve synchronous and accurate drilling. This process relies excessively on manual operation and requires a large amount of non-standard equipment, resulting in high equipment costs and low efficiency. Summary of the Invention

[0003] Therefore, there is a need to provide a device and system for scrapping electricity meters to solve the problem that the position of electricity meters usually needs to be repeatedly adjusted when drilling holes in multiple electricity meters.

[0004] To achieve the above objectives, the inventors provide an energy meter scrapping device, comprising: a drilling unit, a material gripping unit, and a PLC controller;

[0005] The punching unit includes multiple punching components, an X-axis moving component, a Y-axis moving component, and a Z-axis moving component. The punching components are used for punching holes in the electricity meter for scrapping. The Y-axis moving component is mounted on the X-axis moving component and can move along the X-axis direction with the X-axis moving component. There are multiple Y-axis moving components. The Z-axis moving component is mounted on the Y-axis moving component and can move along the Y-axis direction with the Y-axis moving component. There are multiple Z-axis moving components. Among the multiple Z-axis moving components, one is mounted on the X-axis moving component, and the rest are mounted on one of the Y-axis moving components, or multiple Z-axis moving components are mounted on one of the Y-axis moving components. One Z-axis moving component supports one punching component and is used to move the punching component along the Z-axis direction to punch holes in the electricity meter for scrapping.

[0006] The material gripping unit is located on one side of the punching unit and is used to grip the scrapped electricity meter after punching into the material bag;

[0007] The PLC controller is electrically connected to the punching assembly, the X-axis moving assembly, the Y-axis moving assembly, and the Z-axis moving assembly, respectively.

[0008] Furthermore: the material gripping unit includes a linear travel assembly, a first lifting assembly, a first base, a second lifting assembly, a first clamp, a second clamp, and a second base;

[0009] The first lifting component is mounted on the linear travel component and moves along the X-axis or Y-axis direction with the linear travel component. The second lifting component is mounted on the first lifting component through the first seat. The second lifting component and the first seat move along the Z-axis direction with the first lifting component. The first seat has a slot, and the second lifting component passes through the slot.

[0010] The first clamp is mounted on the first base and moves up and down with the lifting of the first base. The second clamp is mounted on the second lifting assembly via the second base and moves along the Z-axis with the second lifting assembly. The size of the first clamp is different from the size of the second clamp.

[0011] Furthermore: the first clamp includes two first clamping parts located on the left side and one second clamping part located on the right side, the two first clamping parts and the one second clamping part being rotatably arranged relative to each other to grip the material;

[0012] The first clamp has multiple clamps arranged side by side. In two adjacent first clamps, the second clamping part of the first clamp on the left is located between the two first clamping parts of the first clamp on the right.

[0013] Furthermore: the second clamp includes a third clamping part located on the left side and a fourth clamping part located on the right side, wherein the right part of the fourth clamping part is bent in the front-back direction;

[0014] There are multiple second clamps arranged side by side. In two adjacent second clamps, the fourth clamping part of the second clamp on the left is offset from the third clamping part of the second clamp on the right by a bent right part.

[0015] Furthermore: there are six first clamps, which are arranged on the first base in two rows along the front and back and in three columns along the left and right directions;

[0016] The second clamp has two clamps, which are arranged on the second base in a row along the front and back and in two columns along the left and right directions, and are located between the two rows of first clamps.

[0017] Furthermore, the vertical length of the first clamping part and the second clamping part of the first clamp is greater than the vertical length of the third clamping part and the fourth clamping part of the second clamp, and the horizontal length of the third clamping part and the fourth clamping part is greater than the horizontal length of the first clamping part and the second clamping part.

[0018] Furthermore: it also includes visual cameras;

[0019] The vision camera is located above the punching unit and is used to capture images of the electricity meter below. The PLC controller is electrically connected to the vision camera and is used to acquire the images captured by the vision camera and identify the placement position, orientation, and barcode position of the electricity meter. Based on the placement position, orientation, and barcode position of the electricity meter, the PLC controller controls the X-axis moving component, Y-axis moving component, and Z-axis moving component corresponding to the position of the electricity meter to drive the punching component to perform scrapping punching.

[0020] Furthermore: the drilling assembly includes a support plate, a drilling motor, a coupling, a drill bit, a pressure block, a guide shaft, a linear bearing, and a compression spring;

[0021] The drilling assembly is supported on the Z-axis moving assembly by the support plate. The drilling motor is mounted on the support plate and connected to the drill bit through the coupling. The drill bit rotates under the drive of the drilling motor to drill holes in the electricity meter to remove it from use.

[0022] The pressure block has a slot for the drill bit to pass through. One end of the guide shaft is located on the pressure block, and the other end passes through the support plate. The support plate is located on the guide shaft via the linear bearing. The compression spring is located between the pressure block and the support plate.

[0023] Furthermore, it also includes a vacuum cleaner, the pressure block is provided with a pagoda connector, one end of the pagoda connector is connected to the slot, and the other end is connected to the vacuum cleaner, the vacuum cleaner is located on one side of the punching assembly.

[0024] To achieve the above objectives, the inventors also provide an electricity meter scrapping system, comprising:

[0025] The shell, which contains a drilling chamber and a lower surface chamber;

[0026] An electricity meter scrapping device, wherein the electricity meter scrapping device is the electricity meter scrapping device described in any of the above embodiments, wherein the drilling unit of the electricity meter scrapping device is located in the drilling chamber, and the material handling unit is located in the lower meter chamber;

[0027] The display panel is located on the outer wall of the housing and is electrically connected to the PLC controller.

[0028] Unlike existing technologies, the above-mentioned technical solution uses a PLC controller to move multiple punching components to their corresponding positions based on the X-axis and Y-axis coordinates of each energy meter. The X-axis moving component moves the corresponding punching component above the corresponding energy meter, and then the PLC controller controls the Z-axis moving component and the punching component to perform discard punching on the energy meter. After punching, the PLC controller uses a material gripping unit to grab the energy meter into a material bag. The positions of the punching components can be adjusted individually, avoiding the need for manual feeding and ensuring the correct orientation of the energy meter bins. This also accommodates drilling requirements where the barcodes of different versions of energy meters are not always in the correct positions, while effectively guaranteeing efficiency.

[0069] Please see Figures 1 to 12 This embodiment of a power meter scrapping device includes: a drilling unit 1, a material gripping unit 2, and a PLC controller;

[0070] The punching unit 1 includes multiple punching components 10, an X-axis moving component 11, a Y-axis moving component 12, and a Z-axis moving component 13. The punching components 10 are used for punching holes in the energy meter 4 before it is scrapped. The Y-axis moving component 12 is mounted on the X-axis moving component 11 and can move along the X-axis direction following the X-axis moving component 11. There are multiple Y-axis moving components 12. The Z-axis moving components 13 are mounted on the Y-axis moving component 12 and can move along the Y-axis direction following the Y-axis moving component 12. There are multiple Z-axis moving components 13. One of the Z-axis moving components 13 is mounted on the X-axis moving component 11, and the remaining ones are each mounted on a Y-axis moving component 12. Alternatively, multiple Z-axis moving components 13 can be mounted on a single Y-axis moving component 12. Each Z-axis moving component 13 supports one punching component 10 and is used to move the punching component 10 along the Z-axis direction to punch holes in the energy meter 4 before it is scrapped. The structure is as follows. Figures 7 to 12 ;

[0071] The material gripping unit 2 is located on one side of the punching unit and is used to grip the scrapped and punched energy meter 4 into the material bag. Its structure is as follows: Figures 1 to 11 ;

[0072] The PLC controller is electrically connected to the punching assembly 10, the X-axis moving assembly 11, the Y-axis moving assembly 12, and the Z-axis moving assembly 13, respectively.

[0073] The X, Y, and Z axes are standard coordinate systems used to describe the position and direction of motion of an object in three-dimensional space. Together, they form a Cartesian coordinate system. The X-axis is the horizontal axis, the Y-axis is the horizontal axis, and the Z-axis is the vertical axis. The X-axis movement component 11 controls the movement of the drilling component 10, the Y-axis movement component 12, and the Z-axis movement component 13 on the horizontal plane. The Y-axis movement component 12 controls the movement of the drilling component 10, the X-axis movement component 11, and the Z-axis movement component 13 on the horizontal plane. The Z-axis movement component 13 controls the vertical lifting movement of a single drilling component 10.

[0074] The Z-axis moving component 13 can be installed in two ways. The first way is that one Z-axis moving component 13 is mounted on the X-axis moving component 11, and the position of this Z-axis moving component 13 is not adjustable in the Y-axis direction. The remaining Z-axis moving components 13 are mounted on the Y-axis moving components 12, with one Z-axis moving component 13 corresponding to one Y-axis moving component 12. The positions of these Z-axis moving components 13 are adjustable in the Y-axis direction. The second way is that all Z-axis moving components 13 are mounted on each Y-axis moving component 12, and the positions of all Z-axis moving components 13 are adjustable in the Y-axis direction.

[0075] Unlike existing technologies, the above-mentioned technical solution allows the PLC controller to move multiple punching components 10 to corresponding positions via the X-axis moving component 11 based on the X-axis and Y-axis coordinates of each energy meter 4. It then moves the corresponding punching components 10 above the corresponding energy meter 4 via the Y-axis moving component 12. Finally, it controls the Z-axis moving component 13 to move the punching components 10 to perform scrap punching on the energy meter 4. After punching, the PLC controller uses the material gripping unit 2 to grab the energy meter 4 into the material bag. The positions of the punching components 10 can be adjusted individually, avoiding the placement requirements of the energy meter 4 material box 3 due to manual feeding, and accommodating the drilling requirements of different versions of energy meters 4 with inconsistent barcode locations, while effectively ensuring efficiency.

[0076] Existing conventional material handling units 2 typically employ a single-specification clamping structure, suitable only for fixed-size energy meters 4. Please refer to... Figure 1In some embodiments, the material gripping unit includes a linear travel assembly 27, a first lifting assembly 21, a first base 23, a second lifting assembly 22, a first clamp 25, a second clamp 26, and a second base 24. The first lifting assembly 21 is mounted on the linear travel assembly 27 and moves along the X-axis or Y-axis direction with the linear travel assembly 27. The second lifting assembly 22 is mounted on the first lifting assembly 21 via the first base 23. The second lifting assembly 22 and the first base 23 move along the Z-axis direction with the first lifting assembly 21. The first base 23 has a slot through which the second lifting assembly 22 passes. The first clamp 25 is mounted on the first base 23 and moves up and down with the first base 23. The second clamp 26 is mounted on the second lifting assembly 22 via the second base 24 and moves along the Z-axis direction with the second lifting assembly 22. The size of the first clamp 25 is different from the size of the second clamp 26.

[0077] A clamp (such as the first clamp 25 and the second clamp 26) is an actuator used to grip an electricity meter (such as electricity meter 4). Its core function is to reliably clamp and release materials through opening and closing actions. Each clamp includes a drive mechanism (such as a cylinder, electric push rod, etc.) and a clamping part. The clamping part is the structural part of the clamp that directly contacts the electricity meter 4. In terms of shape and movement, it is similar to the "fingers" of a human hand—when the clamp is closed, the clamping part moves towards the center, holding the material from both sides or multiple directions; when the clamp is opened, the clamping part separates, releasing the material.

[0078] The first lifting component 21 can control the first clamp 25 and the second clamp 26 to rise or fall together, while the second lifting component 22 can control the second clamp 26 to rise or fall independently. Optionally, the first clamp 25 grips the small energy meter 4, and the second clamp 26 grips the large energy meter 4. If the energy meter is the small energy meter 4, the first clamp 25 is activated, and the second clamp 26 remains in the retracted state. The second clamp 26 can be controlled to rise above the first clamp 25 to avoid interfering with the first clamp 25. If the energy meter is the large energy meter 4, the second clamp 26 is activated, and the second clamp 26 can be controlled to descend below the first clamp 25 to grip the material, while the first clamp 25 remains in a non-interference position.

[0079] This structure can solve the problem that traditional gripping unit 2 cannot handle the gripping of multiple sizes of energy meters 4. For example, it can be compatible with the gripping requirements of single / three-phase meters. Furthermore, through the ingenious dual lifting linkage and clamp avoidance design, it can adapt and grip at least two sizes of energy meters 4 within the same gripping unit 2.

[0080] Please see Figures 1 to 4In some embodiments, the first clamp 25 includes two first clamping parts 251 on the left and one second clamping part 252 on the right. The two first clamping parts 251 and the one second clamping part 252 are rotatably arranged relative to each other to grip materials. There are multiple first clamps 25 arranged side by side. In two adjacent first clamps 25, the second clamping part 252 of the first clamp 25 on the left is located between the two first clamping parts 251 of the first clamp 25 on the right. The first clamping parts 251 and the second clamping parts 252 can be rotated under the drive of a cylinder or an electric push rod to achieve the closing and opening of the clamp. The first clamp 25 has a three-jaw structure, with two first clamping parts 251 arranged side by side in the front-back direction. The gap between them can accommodate one first clamping part 251, forming an interlaced layout, which significantly reduces the minimum installation distance between adjacent first clamps 25, allowing the first base 23 to arrange more first clamps 25 in a limited space.

[0081] Please see Figures 1 to 4 In some embodiments, the second clamp 26 includes a third clamping portion 261 on the left and a fourth clamping portion 262 on the right, with the right portion of the fourth clamping portion 262 bent in the front-back direction. Multiple second clamps 26 are arranged side-by-side. In two adjacent second clamps 26, the fourth clamping portion 262 of the second clamp 26 on the left is offset from the third clamping portion 261 of the second clamp 26 on the right by its bent right portion. The second clamp 26 has a two-claw structure. By using the bent fourth clamping portion 262 to avoid the adjacent third clamping portion 261, the spatial layout is optimized, significantly reducing the minimum installation distance between adjacent first clamps 25, allowing the second base 24 to accommodate more second clamps 26 within a limited space.

[0082] Please see Figure 4 In some embodiments, there are six first clamps 25, arranged in two rows along the front-to-back direction and three columns along the left-to-right direction on the first base 23; there are two second clamps 26, arranged in one row along the front-to-back direction and two columns along the left-to-right direction on the second base 24, and located between the two rows of first clamps 25. The second clamps 26 can rise above the first clamps 25 to avoid obstruction, or descend below the first clamps 25 to perform clamping operations, following the second lifting assembly 22.

[0083] It should be noted that the specific number and arrangement (including the number of rows, columns and relative positions) of the first clamp 25 and the second clamp 26 can be adaptively adjusted according to factors such as the actual arrangement, size and specifications of the electricity meters in the turnover box, production capacity requirements and the installation space of the material gripping unit 2.

[0084] Please see Figure 4In some embodiments, the vertical length of the first clamping portion 251 and the second clamping portion 252 of the first clamp 25 is greater than the vertical length of the third clamping portion 261 and the fourth clamping portion 262 of the second clamp 26, and the horizontal length of the third clamping portion 261 and the fourth clamping portion 262 is greater than the horizontal length of the first clamping portion 251 and the second clamping portion 252. The size of the first clamp 25 is smaller than the size of the second clamp 26; the first clamp 25 is a small clamp, and the second clamp 26 is a large clamp.

[0085] In some embodiments, both the first clamp 25 and the second clamp 26 are pneumatic clamps, meaning that the clamping parts are closed and opened via cylinders. In other embodiments, both the first clamp 25 and the second clamp 26 are hydraulic or electric clamps.

[0086] In some embodiments, the first lifting assembly 21 and the second lifting assembly 22 may be electrically powered linear lifting guide rails. Alternatively, the first lifting assembly 21 and the second lifting assembly 22 may be in the form of electric actuators in conjunction with slide rails.

[0087] Please see Figures 1 to 3 , Figures 5 to 6 In some embodiments, the linear motion assembly 27 includes a base 271, two linear motion guide rails 272, and a sliding plate 273. The base 271 has a hollow area, and the two linear motion guide rails 272 are symmetrically arranged on the left and right sides of the hollow area. The sliding plate 273 spans across the two linear motion guide rails 272 and moves with the two linear motion guide rails 272. The first lifting assembly 21 is disposed on the sliding plate 273 of the linear motion assembly 27. The base 271 may be U-shaped with a hollow area in the middle. The linear motion guide rails 272 include tracks and sliders, and the sliders are slidably connected to the tracks. The linear motion guide rails 272 may be driven by a motor. The sliding plate 273 is mounted on the two sliders and slides with the sliders when the sliders slide. The sliding plate 273 is subjected to balanced force, runs smoothly, and has high positioning accuracy. The sliding of the sliding plate 273 moves the lifting assembly and the gripping unit together to the gripping position.

[0088] In some embodiments, the electricity meter scrapping device further includes a vision camera; the vision camera is located above the drilling unit and is used to capture images of the electricity meter 4 below. The PLC controller is electrically connected to the vision camera and is used to acquire the images captured by the vision camera and identify the placement position, orientation, and barcode position of the electricity meter 4. Based on the placement position, orientation, and barcode position of the electricity meter 4, the PLC controller controls the X-axis movement component 11, Y-axis movement component 12, and Z-axis movement component 13 corresponding to the position of the electricity meter 4 to drive the drilling component 10 to perform scrapping drilling. An industrial vision camera is fixedly installed above the drilling unit, with its lens facing downwards, directly facing the electricity meter 4 in the material bin 3. The vision camera is connected to the PLC controller via a cable. The vision camera collects the placement orientation and position offset information of the electricity meter and sends the offset information to the PLC. After receiving the information, the PLC controller, according to the pre-set program, gives the Y-axis walking position sequence and the X-axis offset information of the drilling component 10 required for the current position, ensuring that the drilling can adapt to the position offset of the meter barcode.

[0089] Please see Figure 7 and Figure 11 In some embodiments, the drilling assembly 10 includes a support plate 100, a drilling motor 101, a coupling 102, a drill bit 103, a pressure block 104, a guide shaft 105, a linear bearing 106, and a compression spring 107. The drilling assembly 10 is supported on the Z-axis moving assembly 13 by the support plate 100. The drilling motor 101 is mounted on the support plate 100 and connected to the drill bit 103 by the coupling 102. The drill bit 103 rotates under the drive of the drilling motor 101 to perform scrapping drilling on the energy meter 4. The pressure block 104 has a slot for the drill bit 103 to pass through. One end of the guide shaft 105 is mounted on the pressure block 104, and the other end passes through the support plate 100. The support plate 100 is mounted on the guide shaft 105 by the linear bearing 106. The compression spring 107 is located between the pressure block 104 and the support plate 100.

[0090] The drilling motor 101 starts, transmitting torque to the drill bit 103 via the coupling 102, causing it to rotate at high speed and enter the electricity meter 4, completing the drilling for scrapping. The support plate 100 serves as a structural support platform, securely mounting the drilling motor 101 and moving up and down with the Z-axis moving assembly 13. When the Z-axis moving assembly 13 drives the entire drilling assembly 10 downwards, the pressure block 104 first contacts the surface of the electricity meter 4. As the Z-axis moving assembly 13 continues to press down, the pressure block 104 stops due to obstruction, pressing the electricity meter 4 firmly. The drill bit 103 continues to rotate under the motor drive, applying force smoothly with the buffering effect of the spring. The guide shaft 105 and the linear bearing 106 form a precision guide pair, preventing the pressure block 104 from deflecting or wobbling at the moment of contact, ensuring the verticality of the drilling. After drilling is completed, the Z-axis moving assembly 13 rises, the compression spring 107 rebounds, and the pressure block 104 returns to its initial position.

[0091] In some embodiments, the electricity meter scrapping device also includes a vacuum cleaner, and the pressure block 104 is provided with a pagoda connector 14, with the structure as follows: Figure 7 As shown, one end of the pagoda connector 14 connects to the slot, and the other end connects to a vacuum cleaner, which is located on one side of the drilling unit. A pagoda connector 14 is integrated into the body of the pressure block 104, and the inner hole of this connector communicates with the slot in the center of the pressure block 104 through which the drill bit 103 passes. The outer interface of the pagoda connector 14 is connected to a vacuum cleaner via a flexible suction hose. When the drilling assembly 10 performs drilling operations, the vacuum cleaner starts simultaneously, generating negative pressure to immediately suck up the plastic debris generated during drilling and transport it through the hose to the dust collection bin of the vacuum cleaner.

[0092] Please see Figure 7 , Figure 9 , Figure 10 and Figure 12 In some embodiments, the electricity meter scrapping device further includes a conveying assembly 17, a material box 3, and a clamping assembly 15. The conveying assembly 17 is located below the X-axis moving assembly 11, and its sidewalls support the X-axis moving assembly 11. The conveying assembly 17 is used to convey the material box 3 containing the electricity meter 2 along the Y-axis direction to a preset position below the punching assembly 10. The clamping assembly 15 includes a clamping telescopic rod 150 and a clamping plate 151. The clamping telescopic rod 150 is located on the sidewall of the conveying assembly 17 and close to one end of the punching assembly 10. The clamping plate 151 is connected to the clamping telescopic rod 150 and is used to contact the material box 3 to limit its movement when the material box 3 moves to the preset position below the punching assembly 10. During operation, the material box 3 moves along the Y-axis direction with the conveying assembly 17 to the preset punching position below the punching assembly 10. Once in position, the PLC controller triggers the clamping telescopic rod 150 to move, causing the clamping plate 151 to move towards the side wall of the material box 3 and fit tightly against it, forming a rigid limit. This limit ensures that the material box 3 remains stationary during subsequent drilling, preventing the material box 3 from sliding or shifting due to the reaction force generated by the downward pressure of the drill bit 103, thus ensuring the drilling position accuracy. After drilling is completed, the clamping plate 151 is released, and the conveying assembly 17 continues to send the material box 3 out to the lower chamber. It should be noted that the clamping telescopic rod can be a rotary cylinder structure to drive the clamping plate 151 to rotate, or a linear cylinder to drive the clamping plate 151 to translate.

[0093] Please see Figure 7 , Figure 8 , Figure 9 and Figure 12In a preferred embodiment, the conveying assembly 17 is a conveying roller assembly, which includes two symmetrically arranged side plates 170, with multiple rotatable conveying rollers 171 mounted parallel between the two side plates 170. Each conveying roller 171 is supported on the two side plates 170 by bearings and is driven to rotate by a conveying motor. The material box 3 is placed on the multiple conveying rollers 171. When the conveying rollers 171 rotate, their surfaces contact the bottom surface of the material box 3 and generate friction, thereby driving the material box 3 to move smoothly along the Y-axis to the preset drilling position below the drilling assembly 10. In some embodiments, the conveying assembly 17 may be a conveyor belt assembly.

[0094] Please see Figure 7 , Figure 9 and Figure 10 In some embodiments, the electricity meter scrapping device further includes a swing limiting component 16, which includes a mounting frame 160, two rotary clamping cylinders 161, and two swing members 162. The two rotary clamping cylinders 161 are respectively mounted on the left and right side plates 170 of the conveying component 17 via a mounting frame 160. The mounting frame 160 may be L-shaped. The swing members 162 are connected to the rotary clamping cylinders 161 and rotate with the drive of the rotary clamping cylinders 161. The two swing members 162 clamp and fix the material box transported to the middle. When one material box moves to a preset position below the punching component 10, the next material box is transported between the two swing members 162 and fixed.

[0095] Please see Figures 7 to 10 In some embodiments, the X-axis moving assembly 11 includes two X-axis guide rails 110 and a base 111. The two X-axis guide rails 110 are arranged side by side along the Y-axis direction, that is, they extend along the X-axis direction and are arranged side by side in the Y-axis direction. The base 111 is disposed on the X-axis guide rails 110. The X-axis guide rails 110 include a track and a slider. The slider can slide along the track and can be fitted with a component that needs to slide, such as the base 111. The base 111 can support the aforementioned Y-axis moving assembly 12 and the aforementioned Z-axis moving assembly 13.

[0096] Please see Figures 7 to 9 In some embodiments, the Y-axis moving assembly 12 includes a Y-axis lead screw and nut module, which includes a Y-axis lead screw 120, a Y-axis nut 121, and a Y-axis motor 122. The Y-axis lead screw 120 is mounted on a base 111 and connected to the Y-axis motor 122, which is also mounted on the base 111. The Y-axis nut 121 is threaded to the Y-axis lead screw 120, and one Y-axis nut 121 supports one Z-axis moving assembly 13. The Y-axis lead screw 120 is parallel to the Y-axis direction. When the Y-axis lead screw 120 rotates, the Y-axis nut 121 can convert the rotational motion into linear motion and drive the Z-axis moving assembly 13 to move along the Y-axis direction to adjust the position of the drilling assembly 10.

[0097] Please see Figures 7 to 10 Preferably, there are two Y-axis moving components 12 and three Z-axis moving components 13. The middle Z-axis moving component 13 is mounted on the base 111 of the X-axis moving component 11, and the two Z-axis moving components 13 on either side are each connected to a Y-axis moving component 12. The Y-axis moving component 12 can adjust the distance between two adjacent drilling components 10 by adjusting the Z-axis moving components 13 on both sides, thus reducing the number of Y-axis moving components 12 and lowering costs.

[0098] Please see Figure 7 and Figure 9 In some embodiments, the Z-axis moving assembly 13 includes a bracket 132 and a Z-axis lead screw and nut module. The Z-axis moving assembly 13 is mounted on the Y-axis moving assembly 12 or the X-axis moving assembly 11 via the bracket 132. The Z-axis lead screw and nut module is mounted on the bracket 132 and supports the punching assembly 10, enabling the punching assembly 10 to move along the Z-axis direction. The Z-axis lead screw and nut module includes a Z-axis lead screw, a Z-axis nut 131, and a Z-axis motor 130. The Z-axis lead screw is mounted on the bracket 132 and connected to the Z-axis motor 130. The Z-axis motor 130 is mounted on the bracket 132. The Z-axis nut 131 is threaded to the Z-axis lead screw, and one Z-axis nut 131 supports one punching assembly 10. When the Z-axis nut 131 moves along the Z-axis direction, it synchronously drives the corresponding punching assembly 10 to move up and down.

[0099] Please see Figure 7 and Figure 9 Preferably, the Z-axis nut 131 of the Z-axis moving assembly 13 supports the support plate 100 of the drilling assembly 10, and the bracket 132 of the Z-axis moving assembly 13 is provided on the Y-axis nut 121 of the Y-axis moving assembly 12 or on the base 111 of the X-axis moving assembly 11.

[0100] In this embodiment, the PLC controller is electrically connected to the drilling assembly 10, the X-axis moving assembly 11, the Y-axis moving assembly 12, the Z-axis moving assembly 13, the conveying assembly 17, the swing limiting assembly 16, the box clamping assembly 15, the first clamp 25, the second clamp 26, the first lifting assembly 21, the second lifting assembly 22, the linear travel assembly 27, and the vision camera, respectively, to control the operation of these components. During operation, the PLC controller controls the conveying assembly to deliver the box to the workstation, and fixes the box to prevent interference through the box clamping assembly and the swing limiting assembly. The vision camera identifies the placement position and barcode coordinates of the energy meter, and the PLC drives the X-axis moving assembly and the Y-axis moving assembly to adjust the horizontal position of the drilling assembly accordingly. The Z-axis moving assembly controls the drill bit to press down vertically to complete precise drilling. After the drilling is completed, the PLC selects to activate the first clamp (small meter) or the second clamp (large meter) according to the size of the electricity meter, and uses the lifting component to achieve clamp avoidance and gripping. Then, the linear travel component moves the scrap meter to the position of the material bag, releases the clamp, and puts the electricity meter into the material belt.

[0101] Please see Figures 13 to 15 This embodiment also provides an electricity meter scrapping system, including:

[0102] Shell 5, which contains a drilling chamber and a lower surface chamber;

[0103] The electricity meter scrapping device is the electricity meter scrapping device described in any of the above embodiments. The drilling unit of the electricity meter scrapping device is located in the drilling chamber, and the material handling unit is located in the lower meter chamber.

[0104] Display panel 6 is located on the outer wall of housing 5 and is electrically connected to the PLC controller.

[0105] Display panel 6 can be used for human-machine interaction and equipment status monitoring. For example, display panel 6 can display key operating parameters of the electricity meter 4 in real time during the scrapping process, including but not limited to: the number of electricity meters currently being processed, the coordinates of the drilling position, the drilling completion status, the fixture working mode (activating the first fixture 25 or the second fixture 26), the material box 3 arrival signal, visual recognition results (such as barcode position offset), equipment alarm information, and operation logs. Operators can manually control or set parameters for the electricity meter scrapping system through display panel 6, such as starting / pausing drilling operations, switching fixtures, calibrating the vision system, resetting fault states, or adjusting the stroke of moving components.

[0106] This section describes the working principle of the electricity meter scrapping device and equipment system:

[0107] Please see Figure 16The feeding process utilizes laser ranging to calculate the number of layers in the material bin. The feeding machine moves along the Z / Y axes to achieve fully automated feeding. Feeding can be done by separating the meters from the material bins, enabling batch feeding. After feeding, the punching assembly directly drills holes in the electricity meters inside the bins, following the bin's flow direction. This method reduces equipment complexity and improves drilling efficiency through multiple punching assemblies operating simultaneously. After drilling, the bin reaches the lower meter compartment, where a gripping unit picks up the meters and loads them into bags. Once the designated number of layers is reached, the bags detach from the frame and enter automatic packaging, thus achieving fully automated feeding and disposal of the dismantled electricity meters.

[0108] Please see Figure 17 The core drilling chamber integrates multi-element visual analysis and multi-axis module control to address issues such as inconsistent meter placement orientation and discrepancies in barcode placement for various specifications and manufacturers. The drilling chamber's visual camera captures and identifies the placement position, orientation, and X / Y coordinates of each asset's barcode, then sends this information to the PLC controller. Upon receiving the information, the PLC calculates and compares the information for each row of meters. If the coordinate deviations of barcodes at different positions within each row are small, drilling proceeds simultaneously. If the deviation exceeds the drilling position requirements, the meters are sequentially translated along the Y-axis based on their distance from the origin. Once at the Y-axis position, the drilling action is performed based on the drilling requirements of different meters at that location, ensuring drilling accuracy. This eliminates the need for strict manual placement of meters, guaranteeing accurate drilling positions. Furthermore, after drilling to the set position, the motor reverses, retracting along the original drilling path to prevent the drill bit from lifting the assets, ensuring the reliability of the drilling operation.

[0109] Drilling and material loading can be controlled on a single traveling track, optimizing the equipment structure. The drilling and pressing modules can be raised and lowered by a single motor, saving costs.

[0110] In summary, the main concept of the electricity meter scrapping device is that the PLC controller obtains the location, orientation, and X / Y coordinate information of the electricity meter's bin to determine the drilling sequence for batches, and then controls the drilling at each station according to the sequence. This directly avoids the requirement for the orientation of the electricity meter bins due to manual loading, accommodates drilling requirements with inconsistent barcode locations on different versions of electricity meters, and effectively ensures efficiency.

[0111] The above technical solution can solve the problems of existing technology requiring the placement of the metering asset on the table, which requires the asset to be placed in the same direction to ensure the accuracy of drilling, and the nature of metering assets with multiple specifications and manufacturers. Even if the assets are loaded in the same direction, the inconsistent placement of the barcodes on the meters from different manufacturers can lead to occasional non-compliant drilling positions.
