Description

Technical Field

[0001] The present invention belongs to the technical field of electricity meter detection, and particularly relates to an automatic classification production line for electricity meters. Background Art

[0002] An electricity meter detection production line is an automated system for efficiently and accurately calibrating and testing electricity meters. The production line usually includes multiple detection units, such as an appearance inspection unit, a withstand voltage test unit, an error calibration unit, etc., and can complete the calibration work of various types of electricity meters simultaneously.

[0003] In the existing automatic electricity meter detection production line, the electricity meters detected with faults in each unit are automatically taken offline and picked out by a sorting unit. However, the faults of the various faulty electricity meters picked out in this detection method are different, and it is impossible to accurately know the faults of the electricity meters themselves when the electricity meters are sent back to the factory for processing. This will increase the workload of the manufacturing workshop during the factory repair, with a high rate of repetitive operations and low repair efficiency. Moreover, when classifying the faulty electricity meters, the sorting efficiency is often low due to the unobvious fault occurrence location, the sorting error is large, and the finished product rate and qualification rate of the electricity meters after factory repair are low.

Detailed implementation manners

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the orientation or positional relationship indicated by terms such as "length", "upper", "lower", "front", "rear", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or several of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0025] Please refer to Figures 1 to 6 , and the automatic classification pipeline for electric energy meters provided by the present invention will be described hereinafter. The automatic classification pipeline for electric energy meters includes a main conveying line 10, an auxiliary conveying line 20, a plurality of labeling mechanisms 30, and a plurality of pushing mechanisms 40; a plurality of detection modules are connected to the main conveying line 10, and the detection modules are used for detecting the functions of the electric energy meters; one end of the auxiliary conveying line 20 is connected to the main conveying line 10, and the other end is connected to a fault shelving area 21; each of the labeling mechanisms 30 is connected to the main conveying line 10 and is electrically connected to each of the detection modules respectively, and the plurality of labeling mechanisms 30 are respectively used for pasting different fault labels on the barcodes of the faulty electric energy meters 50; each of the pushing mechanisms 40 is connected to the main conveying line 10, and the pushing mechanism 40 is used for pushing the faulty electric energy meter 50 to the middle of the main conveying line 10, and one of the pushing mechanisms 40 is used for pushing the faulty electric energy meter 50 on the main conveying line 10 to the auxiliary conveying line 20.

[0026] It should be noted that after each of the detection modules on the main conveying line 10 detects a faulty electric energy meter 50 with a fault, the faulty electric energy meter 50 is pushed to the labeling mechanism 30 by the pushing mechanism 40 for pasting a fault label, and the faulty electric energy meters 50 with different faults are pasted with different fault labels; one of the pushing mechanisms 40 is located at the intersection of the main conveying line 10 and the auxiliary conveying line 20, and can push the faulty electric energy meter 50 on the main conveying line 10 to the auxiliary conveying line 20, so that the electric energy meters are stacked in the fault shelving area 21 for centralized processing.

[0027] The beneficial effect of the automatic classification assembly line of electric energy meters provided by the present invention is that: compared with the prior art, the pushing mechanism 40 adopted by the present invention can push the faulty electric energy meter 50 to the labeling mechanism 30 after the detection module detects the faulty electric energy meter 50, and the labeling mechanism 30 pastes a fault mark on the barcode of the faulty electric energy meter 50. The detection module has multiple detection functions. The faulty electric energy meters 50 with different faults are pasted with different fault marks on the barcode by the labeling mechanism 30. The operator can quickly identify the fault location of the faulty electric energy meter 50 by observing the fault mark, and can quickly classify the faulty electric energy meter 50; the pushing mechanism 40 can also push the faulty electric energy meter 50 to the conveying auxiliary line 20, and the faulty electric energy meter 50 enters the fault holding area 21 through the conveying auxiliary line 20 for centralized processing. During the electric energy meter detection process, the faulty electric energy meter 50 is automatically sorted out and the fault location of each faulty electric energy meter 50 can be clearly displayed, which can avoid repeated operations in the manufacturing workshop, reduce classification errors, and improve the efficiency of returning the faulty electric energy meter 50 to the factory for repair and the qualified rate of the repaired finished products.

[0028] In one possible implementation, see Figures 2 to 5 The labeling mechanism 30 includes a workbench 31, a reel 32, a plurality of reeling rollers 36, a labeling roller 34, a rotating drive member 35 and a reeling roller 36; the workbench 31 is connected to the main conveying line 10, and the workbench 31 is provided with two first chutes 311 which are perpendicular to the main conveying line 10, and the two first chutes 311 are arranged at intervals up and down; the reel 32 is arranged on the workbench 31, and both ends of the reel 32 are rotatably connected to the workbench 31, and the reel 32 is used to wind the coiled material with the fault mark; each take-up roller 33 is spaced apart Distributed on the workbench 31, and both ends are rotatably connected to the workbench 31; the labeling roller 34 is located on the side of the tightening roller 33 away from the unwinding roller 32, and both ends of the labeling roller 34 are rotatably connected with the first slider 341, and the two first sliders 341 are respectively slidably connected to the two first slide grooves 311; the rotary driving member 35 is arranged on the workbench 31, and is located on one side of the labeling roller 34; one end of the winding roller 36 is connected to the output end of the rotary driving member 35, and the other end is rotatably connected to the workbench 31, and the winding roller 36 is used to wind the coil.

[0029] It should be noted that the workbench 31 is connected to the main conveying line 10. The bottom of the first chute 311 is in the same plane as the top of the main conveying line 10. After the first sliders 341 at both ends of the labeling roller 34 are slidably connected to the first chute 311, they can freely slide within the first chute 311, avoiding the limitation of the sliding of the labeling roller 34 caused by the height difference between the main conveying line 10 and the first chute 311, and improving the sliding distance of the labeling roller 34. The unwinding roller 32 is used for winding the coil material. The fault labels are distributed at intervals on the coil material. The coil material is pasted on the surfaces of each tightening roller 33 and the labeling roller 34 and is connected to the winding roller 36 at one end. The rotary driving member 35 drives the winding roller 36 to wind, so that the fault labels on the coil material are on the labeling roller 34. The labeling roller 34 slides within the first chute 311 and abuts against the surface of the faulty electric energy meter 50, and can press the fault label against the outer surface of the faulty electric energy meter 50, so that the fault label is pasted on the bar code of the faulty electric energy meter 50 to cover the bar code.

[0030] The labeling positions of the labeling rollers 34 on each labeling mechanism 30 are different in height. If the detection module detects multiple faulty electric energy meters 50 with faults, the multiple labeling rollers 34 with different labeling position heights can paste the fault labels showing different faults on different positions of the bar code of the faulty electric energy meter 50, avoiding the subsequent pasting of the fault label covering the fault label pasted by the previous-level electric energy meter detection, reducing the sorting error when the subsequent faulty electric energy meters 50 are sent back to the factory for repair, and ensuring the quality of the finished products sent back to the factory for repair.

[0031] In a possible implementation manner, please refer to Figure 4 and Figure 5 , two second chutes 312 perpendicular to the main conveying line 10 are further provided on the workbench 31. The two first chutes 311 are arranged at intervals up and down. The second chute 312 is located between the tightening roller 33 and the labeling roller 34. The labeling mechanism 30 further includes an adjusting roller 37. Second sliders 371 are rotatably connected to both ends of the adjusting roller 37, and the two second sliders 371 are respectively slidably connected to the two second chutes 312.

[0032] It should be noted that the second slide groove 312 is parallel to the first slide groove 311, and the second slide groove 312 is spaced apart from the first slide groove 311. The second slide groove 312 is slidably connected to the adjusting roller 37. When the labeling roller 34 slides in the first slide groove 311 and approaches the faulty electric energy meter 50, the distance between the labeling roller 34 and the winding roller 36 increases, causing the coil on the labeling roller 34 to be tensioned. When the labeling roller 34 is away from the faulty electric energy meter 50, the distance between the labeling roller 34 and the winding roller 36 decreases, and the conveying distance of the coil becomes shorter, so that the coil closely attached to the labeling roller 34 becomes loose, and each roller shaft cannot tighten the coil. The adjusting roller 37 can change its position in the second slide groove 312 when the coil becomes loose, thereby increasing the conveying distance of the coil. The coil is tightened so that it can be tightly attached to the surface of the labeling roller 34 to effectively label the faulty power meter 50; the sliding direction of the adjusting roller 37 and the labeling roller 34 is the same at the same time, and the sliding distance of the adjusting roller 37 in the second slide groove 312 is greater than the sliding distance of the labeling roller 34 in the first slide groove 311, which can produce a displacement difference to change the conveying distance of the coil between each roller shaft; similarly, the adjusting roller 37 can synchronously approach the conveying main line 10 when the labeling roller 34 approaches the faulty power meter 50, and can also produce a displacement difference to change the conveying distance of the coil between the adjusting roller 37 and the labeling roller 34, compensate for the increase in the conveying distance of the coil between the labeling roller 34 and the winding roller 36, keep the conveying distance of the coil unchanged, and avoid excessive tension of the coil causing breakage.

[0033] In order to create a displacement difference between the adjusting roller 37 and the labeling roller 34 during movement, the length of the second slide groove 312 can be greater than the length of the first slide groove 311, so that the sliding distance of the second slider 371 in the second slide groove 312 is greater than the sliding distance of the first slider 341 in the first slide groove 311, so as to ensure that a displacement difference is created between the adjusting roller 37 and the labeling roller 34, compensate for the lack of the coil conveying distance between the labeling roller 34 and the winding roller 36, and ensure that the coil is always stretched tight on the labeling roller 34.

[0034] In one possible implementation, see Figure 4 and Figure 5 A first elastic member 38 is provided on the first slider 341, and a second elastic member 38 is provided on the second slider 371. The first slider 341 is connected to the first slide groove 311 through the first elastic member 38, and the second slider 371 is connected to the second slide groove 312 through the second elastic member 38. The first elastic member 38 is used to push the first slider 341 away from the conveying main line 10, and the second elastic member 38 is used to push the second slider 371 away from the conveying main line 10.

[0035] It should be noted that both the first elastic member 38 and the second elastic member 38 can be springs. One end of the first chute 311 and the second chute 312 close to the conveying main line 10 is closed. The first elastic member 38 is arranged at the closed end of the first chute 311, and the second elastic member 38 is arranged at the closed end of the second chute 312. The first elastic member 38 has an elastic force to push the first slider 341 out of the first chute 311, and the second elastic member 38 has an elastic force to push the second slider 371 out of the second chute 312. That is, when the labeling roller 34 is not affected by an external force, it is located outside the conveying main line 10. When the rotating driving member 35 drives the winding roller 36 to wind, it drives the labeling roller 34 to overcome the elastic force of the first elastic member 38, so that the first slider 341 slides towards the end close to the conveying main line 10 in the first chute 311, and drives the labeling roller 34 to extend into the conveying main line 10 and abut against the outer surface of the faulty electricity meter 50 to label the faulty electricity meter 50. The second elastic member 38 connected to the second slider 371 can push the second slider 371 when the unwinding amount of the coil increases and the coil is loose, so that the adjusting roller 37 moves away from the labeling roller 34 to increase the conveying distance of the coil, and the coil is tightened on the labeling roller 34, ensuring that the coil can always be tightened on each roller shaft and preventing the coil from being loose and causing misalignment of the fault label paste.

[0036] In a possible implementation, please refer to Figure 4 and Figure 5 , a first rotating shaft 313 is rotatably arranged at one end of the first chute 311 away from the conveying main line 10. Two first cams 3131 are arranged on the first rotating shaft 313, and the two first cams 3131 are respectively in contact with the two first sliders 341. A second rotating shaft 314 is rotatably arranged at one end of the second chute 312 away from the conveying main line 10. Two second cams 3141 are arranged on the second rotating shaft 314, and the two second cams 3141 are in contact with the two second sliders 371.

[0037] It should be noted that the first rotating shaft 313 is rotatably connected to the workbench 31, and the first cam 3131 abuts against the first slider 341. When the faulty electricity meter 50 passes by the labeling roller 34, the first rotating shaft 313 rotates, causing the first cam 3131 to push the first slider 341 to slide within the first chute 311 so as to approach the main conveying line 10. Driven by the first slider 341, the labeling roller 34 extends into the main conveying line 10 and can abut against the outer surface of the faulty electricity meter 50 to label the faulty electricity meter 50. The second cam 3141 abuts against the second slider 371 and can push the second slider 371 to slide within the second chute 312 to change the conveying distance of the coil material between the adjusting roller 37 and the labeling roller 34. The convex height of the cam can reflect the maximum distance that the cam pushes the abutting member to move. The larger the convex height, the farther the moving position of the abutting member. The base circle radius of the cam can reflect the distance between the abutting member and the rotating shaft. The smaller the base circle radius, the smaller the distance between the abutting member and the rotating shaft. The convex height of the second cam 3141 can be greater than the convex height of the first cam 3131, and the base circle radius of the second cam 3141 can be smaller than the base circle radius of the first cam 3131, so that the second slider 371 has a longer sliding distance compared to the first slider 341 to achieve the displacement difference between the two, avoiding excessive tension of the coil material when the labeling roller 34 enters the main conveying line 10 and abuts against the faulty electricity meter 50, and also being able to avoid the coil material between the roller shafts from being loose when the labeling roller 34 moves away from the faulty electricity meter 50. The two first cams 3131 respectively abut against the two first sliders 341, and the two second cams 3141 respectively abut against the two second sliders 371, which can ensure the balance of the labeling roller 34 and the adjusting roller 37 in the vertical direction during the moving process, avoiding the deviation of the labeling roller 34 and the adjusting roller 37 from affecting the labeling work of the faulty electricity meter 50.

[0038] In a possible implementation manner, please refer to Figure 4 and Figure 5 , the rotation driving member 35 is in transmission connection with the first rotating shaft 313, and the first rotating shaft 313 is in transmission connection with the second rotating shaft 314.

[0039] It should be noted that the rotation driving member 35 can be a motor. The rotation driving member 35 is connected to the first rotating shaft 313 through a conveyor belt. While the rotation driving member 35 can drive the winding roller 36 to wind and convey the fault label to the labeling roller 34, it can also drive the first rotating shaft 313 to rotate, so that the first cam 3131 pushes the first slider 341, driving the labeling roller 34 to extend into the main conveyor line 10, making the labeling roller 34 abut against the faulty electricity meter 50, so that the fault label can be pasted on the barcode of the faulty electricity meter 50; The first rotating shaft 313 is connected to the second rotating shaft 314 through a conveyor belt. The protrusions of the first cam 3131 and the second cam 3141 always face the same direction. When the labeling roller 34 approaches the main conveyor line 10 and the conveying distance of the coil between the labeling roller 34 and the winding roller 36 increases, the adjusting roller 37 also approaches the main conveyor line 10 to reduce the conveying distance of the coil between the adjusting roller 37 and the labeling roller 34, avoiding the coil from being too tight; When labeling the faulty electricity meter 50, through one drive of the rotation driving member 35, the conveying of the coil and the close abutment between the labeling roller 34 and the faulty electricity meter 50 can be realized, so that the fault label can be successfully pasted on the barcode of the faulty electricity meter 50.

[0040] Please refer to Figure 4 and Figure 5 After the push rod 43 pushes the faulty electricity meter 50 to the side of the main conveyor line 10 close to the labeling roller 34, the labeling roller 34 extends into the main conveyor line 10. While pasting the fault label on the faulty electricity meter 50, it can push the faulty electricity meter 50 offset from the middle of the main conveyor line 10 to the middle of the main conveyor line 10, so that the faulty electricity meter 50 can enter the next-level detection module for detection at the correct detection station after pasting the fault label, ensuring that the labeling unit 18 only pastes the fault label on the faulty electricity meter 50 with faults and ensuring the detection accuracy rate.

[0041] In a possible implementation manner, please refer to Figure 2 and Figure 6 The pushing mechanism 40 includes a base 41, a telescopic driving member 42 and a push rod 43. The base 41 is connected to the main conveyor line 10. The telescopic driving member 42 is arranged on the base 41, and the output end of the telescopic driving member 42 is connected to the push rod 43.

[0042] It should be noted that the telescopic driving member 42 can be a cylinder. One of the telescopic driving members 42 is electrically connected to the first detection unit 11. After the first detection unit 11 detects the faulty electricity meter 50, the first detection unit 11 transmits an electrical signal to the telescopic driving member 42, and the telescopic driving member 42 controls the push rod 43 to push the faulty electricity meter 50 to the side of the main conveyor line 10 close to the labeling roller 34, reducing the distance between the labeling roller 34 and the faulty electricity meter 50, so that the labeling roller 34 can paste the fault label on the barcode of the faulty electricity meter 50.

[0043] In a possible implementation, please refer to Figure 3 , the detection module includes a first detection unit 11, a second detection unit 12, and a third detection unit 13. The first detection unit 11 is used for the appearance detection of the electricity meter, the second detection unit 12 is used for the withstand voltage detection of the electricity meter, and the third detection unit 13 is used for the barcode detection of the electricity meter. A pushing mechanism 40 is connected to one side of both the first detection unit 11 and the third detection unit 13. A plurality of detection rods 121 are slidably arranged on the second detection unit 12, and each detection rod 121 is perpendicular to the main conveying line 10. The detection rods 121 are used for inserting the electricity meter and powering on the electricity meter.

[0044] It should be noted that the first detection unit 11 can detect the appearance of the electricity meter, and the second detection unit 12 can perform the withstand voltage detection on the electricity meter. Before the first detection unit 11 performs the appearance detection, information binding is performed through the barcode on the surface of the electricity meter. The electricity meter passes through the first detection unit 11, and the electricity meters with appearance faults are detected. The faulty electricity meters 50 are pushed to the labeling mechanism 30 electrically connected to the first detection unit 11 by the pushing mechanism 40 electrically connected to the first detection unit 11. The labeling mechanism 30 pastes a fault label indicating an appearance fault on the barcode of the faulty electricity meter 50. The faulty electricity meters 50 with appearance faults and the electricity meters with qualified appearances jointly pass through the second detection unit 12. The electricity meters with unqualified withstand voltage are detected by the second detection unit 12, and the faulty electricity meters 50 are pushed to the labeling mechanism 30 electrically connected to the second detection unit 12. The labeling mechanism 30 pastes a fault label indicating unqualified withstand voltage on the barcode of the faulty electricity meter 50. Each electricity meter passes through the third detection unit 13. The third detection unit 13 can detect the barcode and can judge whether the electricity meter has a fault according to the barcode occlusion situation. The faulty electricity meters 50 are pushed to the auxiliary conveying line 20 by the electrically connected pushing assembly, and the electricity meters are stacked in the fault shelving area 21 for centralized processing.

[0045] A conductive plate can be provided on the detection rod 121. The detection rod 121 can push the conductive plate into the electricity meter for withstand voltage testing, and can continue to push out the detection rod 121 when a faulty electricity meter 50 is detected, pushing the faulty electricity meter 50 close to the labeling roller 34 to realize the pasting of the fault label on the faulty electricity meter 50, which can reduce the installation quantity of the pushing mechanism and realize the linkage cooperation of the detection production line.

[0046] In a possible implementation, please refer to Figure 6 , a barcode scanner 131 is provided on the side of the third detection unit 13 away from the pushing mechanism 40. The barcode scanner 131 is electrically connected to the pushing mechanism 40 on one side of the third detection unit 13. When the barcode scanner 131 fails to verify the barcode, the pushing mechanism 40 on one side of the third detection unit 13 pushes the electricity meter to the auxiliary conveying line 20.

[0047] It should be noted that the barcode scanner 131 can be a laser barcode scanner, which can detect the barcode on the surface of the electricity meter passing through the third detection unit 13. When the barcode is detected, it proves that the electricity meter is qualified. If the barcode is not detected, it means that a fault identification is pasted on the barcode. The third detection unit 13 transmits an electrical signal to the pushing mechanism 40, and the pushing mechanism 40 pushes the faulty electricity meter 50 to the auxiliary conveying line 20 and conveys it to the fault storage area 21 for stacking, waiting for subsequent repair at the factory.

[0048] In a possible implementation manner, please refer to Figure 1 , the detection module further includes a multi-functional verification unit 14. The main conveying line 10 is sequentially connected with a feeding unit 15, a laser coding unit 16, a sealing unit 17, a labeling unit 18 and a discharging unit 19. Among them, the first detection unit 11 and the second detection unit 12 are located between the feeding unit 15 and the multi-functional verification unit 14, and the third detection unit 13 is located between the multi-functional verification unit 14 and the laser coding unit 16.

[0049] It should be noted that both the feeding unit 15 and the discharging unit 19 are operated by robots. The electricity meter is cached before verification before entering the multi-functional verification unit 14 and cached after verification after passing through the multi-functional verification. The outlet of the multi-functional verification unit 14 can also be electrically connected to a labeling mechanism 30 and a pushing mechanism 40, which can paste a fault identification on the unqualified faulty electricity meter 50. After the screening of the faulty electricity meter 50 is completed, it is conveyed by the main conveying line 10 to the laser coding unit 16 for coding operation; the main conveying line 10 conveys the qualified electricity meter after laser coding to the sealing unit 17 for sealing, and the sealed qualified electricity meter is labeled with a certificate by the labeling unit 18 and stored in the warehouse by the discharging unit 19.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
