[0001] This invention belongs to the technical field of intelligent production line for copper busbar processing, and relates to an intelligent production line and method for automatic feeding and recycling of surplus materials in copper busbar processing. It can realize automatic stacking, automatic warehousing / outbound of copper busbars, automatic feeding and automatic recycling of surplus materials. Background Technology

[0002] Copper busbars are important conductive components widely used in power distribution systems. They are typically produced by processing copper busbars using a busbar processing machine. Copper busbars are the raw material for processing copper busbars.

[0003] Currently, the production and processing of copper busbars has achieved functions such as automatic stacking, automatic warehousing, and automatic warehousing. However, it lacks the function of recycling the surplus material generated after the copper busbar processing is completed, and the copper busbar warehouse is usually a flat-floor structure, occupying a large area. The current copper busbar processing production line mainly faces the following technical problems that need to be solved: 1. The problem of recycling leftover materials after the processing of copper busbars; 2. The large floor area of ​​the copper busbar warehouse increases the production cost of the production line, and the long stroke of the robotic arm for picking up materials leads to a longer production cycle of copper busbars; 3. When copper busbars are put into storage, the model of the copper busbars is generally determined by laser ranging. The laser ranging structure is complex and the identification time is long, which prolongs the production cycle of copper busbars. Summary of the Invention

[0012] A method for automatic feeding and waste material recycling in copper busbar processing, using the aforementioned intelligent production line for automatic feeding and waste material recycling in copper busbar processing, includes the following steps: Copper busbar storage: Rotate to open a pair of rotating supports, so that the auxiliary guide rail on the rotating supports aligns with the bottom copper busbar guide rail inside the main frame of the copper busbar storage. The copper busbar storage drawer moves along the copper busbar guide rail and the auxiliary guide rail to the storage position. The operator stores the copper busbars according to their specifications and sizes into the corresponding placement compartments in the copper busbar storage drawer. The copper busbar storage drawer moves along the auxiliary guide rail and the copper busbar storage rail to the loading position. Close the rotating supports. The control system controls the copper busbar loading gantry robot to take out the copper busbars from the copper busbar storage drawer and transport them to the vision camera to identify the specifications and models of the copper busbars. The identification results are transmitted to the control system. The control system controls the copper busbar storage drawer with available space for the corresponding specifications and models to move to the storage position. The copper busbar loading gantry robot places the copper busbars into the empty space of the copper busbar storage drawer. Copper busbar loading: The roller conveyor in the copper busbar silo, the copper busbar loading roller conveyor, and the residual material recovery roller conveyor are started. The centering mechanism on each roller conveyor is adjusted to match the specifications and models of the copper busbars to be processed. The control system controls the copper busbar storage drawer containing the copper busbars of the specified specifications and models to move to the loading position. The copper busbar loading gantry robot grabs the copper busbar, the copper busbar storage drawer is reset, and the copper busbar loading gantry robot places the copper busbar between a pair of clamping bars on the roller conveyor in the copper busbar silo. The copper busbar is conveyed to the busbar machine through the roller conveyor in the copper busbar silo and the copper busbar loading roller conveyor. The busbar machine processes the copper busbar into copper busbars. Residual material recycling: The control system calculates and determines whether there is residual material and whether the length of the residual material is within the recycling length range. If so, the residual material recycling roller line works in conjunction with the residual material recycling gantry robot to recycle the residual material.

[0013] Preferably, the control system sends a prompt signal to the on-site staff, who then place the surplus material from the copper busbar feeding roller line onto the surplus material recycling roller line. The surplus material recycling roller line transports the surplus material towards the surplus material storage area. When the fifth proximity switch on the surplus material recycling roller line detects the arrival of the surplus material, the control system stops the surplus material recycling roller line. The surplus material recycling gantry robot grabs the surplus material, and the surplus material storage drawer corresponding to the surplus material specification moves to the recycling position. The surplus material recycling gantry robot then places the surplus material into the surplus material storage drawer.

Detailed Implementation

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Example 1:

[0018] like Figure 1-9As shown, an intelligent production line for automatic feeding and waste material recycling of copper busbars includes a busbar machine 1. The left side of the busbar machine 1 is the copper busbar outlet, and the right side is the copper busbar inlet. The busbar machine 1 is used to process copper busbars into copper busbars. A waste material recycling roller line 3, a copper busbar feeding roller line 2, and a waste material storage main frame 4 are arranged parallel to each other on the right side of the busbar machine 1's inlet. The waste material recycling roller line 3 is located in front of the copper busbar feeding roller line 2, and the waste material storage main frame 4 is located behind the copper busbar feeding roller line 2. The right end of the copper busbar feeding roller line 2 is connected to an inner roller line 11 inside the copper busbar storage main frame 9. The copper busbar feeding roller line 2 and the inner roller line 11 are flush. The inner roller line 11 is located in the middle of the width direction inside the copper busbar storage main frame 9. The inner roller line 11 and the copper busbar feeding roller line 2 constitute a copper busbar feeding system. The main frame 4 of the waste material storage silo includes a waste material storage frame set on the ground behind the copper busbar feeding roller line 2, and a horizontal support frame located on top of the waste material storage frame. The front end of the horizontal support frame is located above the waste material recycling roller line 3. Several layers of paired waste material storage guide rails are set inside the waste material storage frame of the main frame 4. The waste material storage drawers 6 are rolled on the waste material storage guide rails at both ends. The waste material storage drawers 6 are located on the rear side of the main frame 4. The height of two adjacent layers of waste material storage guide rails is greater than the height of the waste material storage drawers 6. A waste material recycling gantry robot 5 capable of horizontal and vertical movement is installed on the horizontal support frame of the main frame 4. The main frame 9 of the copper busbar storage unit also has several layers of copper busbar storage guide rails 10 (flexibly configured according to the height of the main frame 9 and customer needs). Each layer of copper busbar storage guide rails 10 includes two parallel copper busbar storage guide rails 10 arranged on the left and right sides. The copper busbar storage guide rails 10 are aligned with the width of the main frame 9. The left and right ends of the copper busbar storage drawers 7 are slidably mounted on the copper busbar storage guide rails 10. A copper busbar loading gantry robot 8 capable of horizontal and vertical movement is movably mounted on the main frame 9. A copper busbar storage drawer 18 is slidably mounted on the bottom layer of copper busbar storage guide rails 10, and a pair of copper busbar storage drawers 7 are slidably mounted on the guide rails 10 of other layers. The pair of copper busbar storage drawers 7 are located on the front and rear sides inside the main frame 9 of the copper busbar storage unit.

[0019] A pair of rotating brackets 12 with a double-door structure are rotatably installed at the lower front ends of the main frame 9 of the copper busbar storage unit. The rotating brackets 12 are hinged to the main frame 9 and are opened and closed manually. Each rotating bracket 12 has an auxiliary guide rail 17 on its inner side, at the same height as the lowest copper busbar storage guide rail 10 inside the main frame 9. When the rotating bracket 12 is opened forward at 90°, the inner end of the auxiliary guide rail 17 aligns with the end of the lowest copper busbar storage guide rail 10, facilitating the horizontal movement of the copper busbar storage drawer 18 and enabling automatic copper busbar storage. The height of the roller conveyor 11 inside the copper busbar storage unit is higher than the lowest copper busbar storage guide rail 10 inside the main frame 9, and the height of adjacent copper busbar storage guide rails 10 is greater than the height of the copper busbar storage drawer 7 and the copper busbar storage drawer 18.

[0020] The main frame 9 of the copper busbar storage unit is a rectangular steel frame. A pair of copper busbar loading beams are installed above the main frame 9, with the width of the loading beams aligned with the width of the main frame 9. A loading gantry robot 8 is mounted on these beams. The loading gantry robot 8 is existing technology and includes a drive mechanism and a suction cup gripper. The drive mechanism (including motor drive, hydraulic cylinder, or pneumatic cylinder drive) is existing technology, enabling the suction cup gripper to move forward, backward, up, and down. The suction cup gripper itself is also existing technology and will not be described further.

[0021] The copper busbar storage drawer 18 is a rectangular frame base welded from square steel tubes. First baffles 24 are welded to the upper surfaces of both ends of the frame base along its length. A rack 14 is fixedly installed on the bottom copper busbar storage guide rail 10. Rollers 15 and gears 16 are rotatably installed at both ends of the copper busbar storage drawer 18, respectively. The gears 16 mesh with the rack 14, and the rollers 15 roll along the upper surface of the copper busbar storage guide rail 10, avoiding the rack 14. A drive motor 20 and a gear set 21 are fixedly installed in the middle of the frame base of the copper busbar storage drawer 18. The drive motor 20 is connected to the gear set 21, which is also connected to the rotating shaft 22. The rotating shaft 22 runs parallel to the length of the frame base of the copper busbar storage drawer 18, and its end is rotatably connected to the frame base. The gear 16 is fixedly located at the end of the rotating shaft 22. The drive motor 20 controls the rotation of the gear 16, causing the copper busbar storage drawer 18 to move horizontally. A vision camera 13 is fixedly installed on the copper busbar storage guide rail 10 above the roller conveyor 11 inside the copper busbar storage compartment. Several vertically aligned dividers 23 are arranged along the width direction of the copper busbar storage drawer 18 inside the two first baffles 24. The dividers 23 engage with positioning holes on the frame base, and adjacent dividers 23 form storage compartments for copper busbars. The spacing between the dividers 23 varies, and the number of positioning holes is greater than or equal to the number of dividers 23. The position of the dividers 23 can be adjusted according to the width of the copper busbars (set according to customer processing requirements, and the control system program is adjusted accordingly) to accommodate various copper busbar width specifications.

[0022] The structures of the scrap material storage drawer 6 and the copper busbar storage drawer 7 are similar to those of the copper busbar storage drawer 18. The width of the copper busbar storage drawer 18 is greater than that of the copper busbar storage drawer 7, and less than the distance between the front side of the main frame 9 of the copper busbar storage and the front side of the roller line 11 inside the storage, so as to maximize the quantity of copper busbars loaded each time. The length of each rack 14 is adapted to the moving distance of the scrap material storage drawer 6, the copper busbar storage drawer 7, and the copper busbar storage drawer 18, and a first proximity switch 19 is provided at the end of the rack 14. The first proximity switch 19 can prevent the scrap material storage drawer 6, the copper busbar storage drawer 7, and the copper busbar storage drawer 18 from derailing, and detect whether the scrap material storage drawer 6, the copper busbar storage drawer 7, and the copper busbar storage drawer 18 have moved into place.

[0023] Each copper busbar storage drawer 7 stores copper busbars of the same size and specifications. The copper busbars stored in the copper busbar storage drawers 7 from bottom to top are arranged in descending order of specifications (based on the width of the copper busbars) (specific settings are determined according to customer requirements).

[0024] Each scrap material storage drawer 6 stores scrap materials of the same size and specifications, but only one scrap material per layer. This is because the remaining length of the scrap materials cannot be guaranteed to be consistent, and storing them one scrap material per layer facilitates the gantry robot 5's handling of the scrap material. Since the scrap materials are stored one scrap material per layer, the height of the divider bars 23 on the scrap material storage drawer 6 only needs to be adapted to the height of the single-layer scrap material.

[0025] like Figure 10 , 13 As shown in Figure 14, the inner roller conveyor 11 of the copper busbar silo includes a first roller mill and two first centering mechanisms 25. The first roller mill adopts existing technology, and the first centering mechanisms 25 are located at both ends of the first roller mill along its length. The distance from one side of the main frame 9 of the copper busbar silo to the inner roller conveyor 11 is greater than twice the width of the copper busbar storage drawer 7, ensuring that the copper busbar storage drawer 7 is unobstructed from above when it is in the loading position.

[0026] The first centering mechanism 25 includes a fixed base, a gear and rack mechanism, a centering motor 42, centering guide rails 40, centering sliders, and a first clamping rod 26. The fixed base is fixedly installed below the first roller mill. The fixed base has an inverted n-shaped structure. The centering motor 42 is located at the center of the lower surface of the fixed base. Two centering guide rails 40 are arranged parallel to each other on the upper surface of the fixed base. Aligning sliders 39 and 41 are slidably connected to the centering guide rails 40 on their adjacent sides. Gear rack mounting plates are fixedly installed on the opposite sides of the alignment sliders 39 and 41. Centering racks 44 are fixedly installed on the gear rack mounting plates. The shaft of the centering motor 42 passes through the fixed base and is fixedly connected to the centering gear 43. The centering gear 43 meshes with the two centering racks 44 for transmission. A clamping rod mounting plate is provided on the upper surface of the gear rack mounting plate. The first clamping rod 26 in a vertical direction is fixedly installed on the clamping rod mounting plate and extends out between adjacent rollers of the first roller mill. The first clamping rod 26 has a first threaded hole 38 at its top end.

[0027] like Figure 11 , 15 As shown, the structure of the copper busbar feeding roller line 2 is similar to that of the copper busbar storage roller line 11, including a second roller machine and two second centering mechanisms 29. The second centering mechanisms 29 are provided at both ends of the length direction of the second roller machine. A fourth proximity switch 30 with upward sensing is provided between the roller gaps at the end of the second roller machine near the busbar machine 1. The second centering mechanism 29 is similar in structure to the first centering mechanism 25. The second centering mechanism 29 is provided with a second clamping bar 32. The top end of the second clamping bar 32 is provided with a second threaded hole. The two ends of the first clamping plate 31 are provided with slots 46 for accommodating the second clamping bar 32. Screws 45 pass through the surface of the first clamping plate 31 above the slots 46 and are screwed into the second threaded holes, thereby fixing the first clamping plate 31 to the top of the pair of second clamping bars 32.

[0028] The height of the waste material recycling roller line 3 is flush with that of the copper busbar feeding roller line 2. For example... Figure 12 As shown, the waste material recycling roller line 3 includes a third roller mill and a pair of third centering mechanisms 33. The third centering mechanism 33 is structurally similar to the second centering mechanism 29. A third clamping bar 35 is installed on the third centering mechanism 33, and a second clamping plate 34 is installed on the third clamping bar 35. A fifth proximity switch 36 and a second baffle 37 are provided at the right end of the third roller mill of the waste material recycling roller line 3. When the waste material is conveyed past the fifth proximity switch 36, the fifth proximity switch 36 is triggered. After 5 seconds (ensuring that the waste material contacts the second baffle 37), the third roller mill of the waste material recycling roller line 3 stops conveying.

[0029] The waste material recycling gantry robot 5 is existing technology and has a similar structure to the loading gantry robot 8.

[0030] The drive motor 20 is a servo motor, whose movement distance is preset and it moves the corresponding distance according to the control signal issued by the control system.

[0031] Example 2:

[0032] A method for automatic feeding and waste material recycling in copper busbar processing, employing the intelligent production line for automatic feeding and waste material recycling in copper busbar processing described in Example 1, includes the following steps: 1. Copper busbar storage: Manually open the rotating bracket 12, and the copper busbar storage guide rail 10 and auxiliary guide rail 17 are connected. The copper busbar storage drawer 18 automatically moves to the material release position along the bottom copper busbar storage guide rail 10 and auxiliary guide rail 17. The copper busbars are manually stored in the corresponding placement compartments in the copper busbar storage drawer 18 according to their specifications and sizes, and the number of the placement compartment containing the copper busbars is stored in the control system.

[0033] After the copper busbar storage drawer 18 automatically moves to the loading position along the auxiliary guide rail 17 and the bottom copper busbar storage guide rail 10, the rotating bracket 12 is manually closed.

[0034] The control system controls the copper busbar loading gantry robot 8 to move and take out copper busbars from the copper busbar storage drawer 18 in sequence according to the settings. The copper busbars are then transported to the vision camera 13. The vision camera 13 takes pictures of the end section of the copper busbar and identifies the size of the copper busbar section, thus completing the identification of the copper busbar specifications and models. The identification results are then transmitted to the control system. Based on the copper busbar specifications and models identified by the vision camera 13, the control system controls the copper busbar storage drawer 7 with available spaces to move to the storage position. The control system then controls the copper busbar loading gantry robot 8 to place the copper busbars into the empty spaces of the copper busbar storage drawer 7.

[0035] 2. Copper discharge and loading: The control system receives the specifications and model of the copper busbar to be processed, controls the start of the copper busbar storage roller line 11, the copper busbar feeding roller line 2 and the surplus material recovery roller line 3, and adjusts the centering mechanism on each roller line to the appropriate position according to the specifications and model of the copper busbar. The control system controls the copper busbar storage drawer 7, which stores the copper busbar of this specification and model, to move to the loading position. The control system then controls the copper busbar loading gantry robot 8 to grab the copper busbar, and the copper busbar storage drawer 7 is reset. The control system controls the copper busbar loading gantry robot 8 to place the copper busbar between a pair of first clamping bars 26 on the inner roller line 11 of the copper busbar silo. The copper busbar is then transported to the busbar machine 1 via the inner roller line 11 and the copper busbar loading roller line 2. The busbar machine 1 processes the copper busbar into a copper busbar.

[0036] 3. Waste material recycling: After the copper busbar is processed, the control system calculates and determines that there is excess material with a length greater than 500mm. The control system then sends a signal to the on-site personnel, who remove the excess material from the copper busbar feeding roller line 2 and place it on the excess material recycling roller line 3. The recycling roller line 3 then transports the excess material towards the excess material storage area. When the fifth proximity switch 36 detects the arrival of excess material, the control system stops the excess material recycling roller line 3, activates the excess material recycling gantry robot 5 to grab the excess material, moves the corresponding excess material storage drawer 6 to the recycling position, and finally places the excess material into the storage drawer 6.

[0037] Since the copper busbar is typically 6 meters long, the length cut off during processing is known, and the remaining length can be calculated.

[0038] The control system uses PLC control, and the information exchange methods with various devices (motors, sensors) are not limited to I / O signal connection, network communication, etc. (selected according to customer needs).

[0039] In the embodiments of the present invention, all technical features not described in detail are existing technologies or conventional technical means, and will not be repeated here.

The scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that any person skilled in the art can modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the technical scope disclosed in the present invention, or make equivalent substitutions for some of the technical features; and these modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered within the scope of protection of the present invention.
