Description

Technical Field

[0001] This invention relates to the field of conveying devices, specifically a conveying device for an automatic lamination production line for transformer cores. Background Technology

[0002] Transformers are manufactured based on the principle of electromagnetic induction. The magnetic circuit is the medium for converting electrical energy, and the iron core is the main magnetic circuit of the transformer. Its main function is to conduct magnetism, converting electrical energy from the primary circuit into magnetic energy, and then from magnetic energy into electrical energy in the secondary circuit. At the same time, the iron core is also the mechanical skeleton of the transformer. The clamping device of the iron core not only makes the magnetic conductor a mechanically complete structure, but also houses insulated coils that support the leads and almost all the internal components of the transformer. The iron core is the heaviest component of the transformer, accounting for about 60% of the total weight in dry-type transformers and about 40% in oil-immersed transformers.

[0003] The iron core is a rectangular frame made of silicon steel laminations. In the traditional iron core lamination production line, the silicon steel laminations are automatically stacked onto the stacking table by a robotic arm, and then the stacking table and the stacked iron core are transported to the next process by an RGV trolley.

[0004] RGV is an abbreviation for Rail Guided Vehicle, also known as a rail shuttle vehicle. RGV vehicles can be used in warehouses with various high-density storage methods. The vehicle aisles can be designed to be of any length, which can increase the overall storage capacity of the warehouse. Moreover, no forklifts need to enter the aisles during operation, making it safer.

[0005] The base used to place the stacking table needs to be equipped with a conveying component to transport the stacking table to the RGV trolley. Thus, the base where multiple processes are located needs to be equipped with drive motors to drive the conveying components. The large number of drive motors increases the equipment cost and maintenance cost. In order to further reduce the number of drive motors, a conveying device for an automatic lamination production line for transformer cores is provided. Summary of the Invention

[0006] The purpose of this invention is to provide a conveying device for an automatic lamination production line for transformer cores, in order to solve the problem.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for an automatic lamination production line for transformer cores, comprising an RGV trolley and a workbench with a base, wherein two top support plates are symmetrically fixedly connected to the top of the RGV trolley, and a fixed rotating rod is rotatably connected to the middle position of the two top support plates, and two sets of extension components are symmetrically arranged on the inner side of the two top support plates with the fixed rotating rod as the center, the extension components being used to dock the RGV trolley with the workbench;

[0010] The rotating arm is symmetrically rotatably connected to the ends of two fixed side plates that are far apart from each other. The linkage gear and the fixed gear are located on the side of the rotating arm that is far away from the fixed side plates and are close to the upper and lower ends of the rotating arm, respectively. The rack is fixed to one side of the top support plate and extends to the bottom of the fixed gear. The fixed gear is fixedly connected to the rotating arm and meshes with the rack.

[0011] The base has a third conveying assembly on its top inner side. The first conveying assembly a, the second conveying assembly b, and the third conveying assembly c are all composed of conveying rollers, transmission gears, and transmission toothed belts. The transmission gears are arranged in two sets and symmetrically distributed at both ends of the conveying rollers. Each set of transmission gears includes two transmission gears. There are multiple conveying rollers. The transmission toothed belt is sleeved on the outside of two aligned transmission gears on two adjacent conveying rollers to realize the same-direction transmission of the two conveying rollers.

[0012] The conveying rollers in the first conveying assembly, the second conveying assembly, and the third conveying assembly are respectively rotatably connected to the fixed side plate, the rotating arm, and the base.

[0015] The base is distributed at both ends of the RGV trolley. The first driven gear and the second driven gear mesh with each other and are rotatably connected to the outer walls of the base. The conveying roller located at the end of the base near the RGV trolley is connected to the second driven gear through the conveying roller. The rotating arm that rotates downward to a horizontal state drives the linkage gear to mesh with the first driven gear, which is used to realize the linkage between the second conveying component and the third conveying component.

[0016] As a further embodiment of the present invention: a conveying roller located at the outermost end of the fixed side plate in the first conveying assembly and a conveying roller located at the lowermost end of the rotating arm in the second conveying assembly are connected by a transmission toothed belt to realize the linkage between the first conveying assembly and the second conveying assembly.

[0017] As a further embodiment of the present invention: a telescopic transmission assembly for providing driving force to the first conveying assembly, the second conveying assembly, and the third conveying assembly is provided between the top support plate and the fixed side plate;

[0018] The telescopic transmission assembly includes a drive gear, a first moving gear, a second moving gear, and a linkage toothed belt;

[0019] The drive gear is rotatably connected to both sides of the top support plate. The first moving gear and the second moving gear are located on the outside of the top support plate and are rotatably connected to the fixed side plate through the connecting shaft. The first moving gear is rotatably connected to the fixed side plate. The connecting shaft of the second moving gear passes through the fixed side plate and is connected to another conveying roller in the first conveying assembly. The drive gear, the first moving gear, and the second moving gear are staggered from bottom to top.

[0020] The drive gear, the first moving gear, and the second moving gear are arranged in two sets and are symmetrically distributed. The linkage toothed belt is S-shaped and sleeved on the outside of the two sets of drive gears, the first moving gear, and the second moving gear, so as to realize the linkage of the two sets of first conveying components in the two sets of extension components.

[0021] A limiting groove is provided at the contact position between the top support plate and the connecting shaft of the first moving gear and the second moving gear, which provides space for the movement of the connecting shaft when the first moving gear and the second moving gear move horizontally;

[0022] The RGV trolley is equipped with a dual-axis motor on its top. The two output ends of the dual-axis motor pass through two top support plates and are connected to two of the drive gears in a set of drive gears.

[0023] As a further embodiment of the present invention: the L-shaped limiting plate is symmetrically fixed to the outer wall of the two fixed side plates and fits against the outer wall of the rotating arm, and is used to limit the rotating arm in the vertical state and to support the rotating arm in the horizontal state.

[0024] As a further aspect of the present invention: the travel length of the connecting shaft of the first moving gear and the second moving gear inside the limiting slide groove is matched with the semi-circular trajectory length of the fixed gear.

[0025] As a further embodiment of the present invention: the number of fixed rotating rods is set to multiple, and the multiple fixed rotating rods are evenly distributed between the two top support plates and located between the two sets of extension components.

[0026] As a further embodiment of the present invention: the top horizontal height of the conveying roller in the first conveying assembly is the same as the top horizontal height of the conveying roller in the third conveying assembly, and when the rotating arm rotates to a horizontal state, the top horizontal height of the second conveying assembly is level with the tops of the first conveying assembly and the third conveying assembly.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] By setting an extension component to drive the moving seat through an electric push rod, the rotating arm can move and rotate, thereby engaging the linkage gear with the first transmission gear. This achieves the linkage of the first, second, and third conveying components. The telescopic transmission component can drive the three conveying components to run synchronously and in the same direction, thus realizing the transfer operation of the stacking table. Moreover, there is no need to install a motor inside the worktable, effectively reducing the purchase and maintenance costs of the worktable. Attached Figure Description

The following describes embodiments of the invention based on its overall structure.

[0039] Please see Figures 1 to 7In this embodiment of the invention, a conveying device for an automatic lamination production line for transformer cores includes an RGV trolley 1 and a workbench 7 with a base 701. Two top support plates 2 are symmetrically fixedly connected to the top of the RGV trolley 1. A fixed rotating rod 3 is rotatably connected to the middle position of the two top support plates 2. Two sets of extension components 4 are symmetrically arranged on the inner side of the two top support plates 2 with the fixed rotating rod 3 as the center. The extension components 4 are used to dock the RGV trolley 1 with the workbench 7.

[0040] The extension assembly 4 includes a fixed bracket 401, an electric push rod 402, a movable seat 403, a fixed side plate 404, a rotating arm 405, a linkage gear 406, a fixed gear 407, a rack 408, an L-shaped limiting plate 409, and a first conveying assembly 5a and a second conveying assembly 5b.

[0041] The electric push rod 402 is fixedly installed between the two top support plates 2 by the fixed bracket 401. The movable seat 403 is slidably connected between the two top support plates 2 and connected to the output end of the electric push rod 402. The fixed side plate 404 is symmetrically fixed to the top of the movable seat 403. The electric push rod 402 and the movable seat 403 extend and protrude from the side of the top support plate 2.

[0042] The rotating arm 405 is symmetrically rotatably connected to the two fixed side plates 404 at opposite ends. The linkage gear 406 and the fixed gear 407 are located on the side of the rotating arm 405 away from the fixed side plates 404 and are close to the upper and lower ends of the rotating arm 405 respectively. The rack 408 is fixed to one side of the top support plate 2 and extends to the bottom of the fixed gear 407. The fixed gear 407 is fixedly connected to the rotating arm 405 and meshes with the rack 408.

[0043] A third conveying component 5c is provided on the inner side of the top of the base 701. The first conveying component 5a, the second conveying component 5b, and the third conveying component 5c are all composed of conveying rollers 501, transmission gears 502, and transmission toothed belts 503. There are two sets of transmission gears 502, which are symmetrically distributed at both ends of the conveying rollers 501. Each set of transmission gears 502 includes two transmission gears 502. There are multiple conveying rollers 501. The transmission toothed belts 503 are sleeved on the outer sides of two aligned transmission gears 502 on two adjacent conveying rollers 501 to realize the same direction of transmission of the two conveying rollers 501.

[0044] The conveying rollers 501 in the first conveying assembly 5a, the second conveying assembly 5b, and the third conveying assembly 5c are respectively rotatably connected to the fixed side plate 404, the rotating arm 405, and the base 701.

[0045] The conveying roller 501 located at the top of the rotating arm 405 passes through the rotating arm 405 and is fixedly connected to the linkage gear 406.

[0046] The worktable 7 also includes a first driven gear 702 and a second driven gear 703;

[0047] The base 701 is distributed at both ends of the RGV trolley 1. The first driven gear 702 and the second driven gear 703 mesh with each other and are rotatably connected to the outer walls of the base 701. The conveying roller 501 located at the end of the base 701 near the RGV trolley 1 passes through the conveying roller 501 and is connected to the second driven gear 703. The rotating arm 405 rotates downward to a horizontal state and drives the linkage gear 406 to mesh with the first driven gear 702, which is used to realize the linkage between the second conveying component 5b and the third conveying component 5c.

[0048] In the first conveying assembly 5a, a conveying roller 501 located at the outermost end of the fixed side plate 404 is connected to the second conveying assembly 5b, a conveying roller 501 located at the lowermost end of the rotating arm 405, via a transmission toothed belt 503, so as to realize the linkage between the first conveying assembly 5a and the second conveying assembly 5b.

[0049] The top horizontal height of the conveying roller 501 in the first conveying assembly 5a is the same as the top horizontal height of the conveying roller 501 in the first conveying assembly 5a, and when the rotating arm 405 rotates to the horizontal state, the top horizontal height of the second conveying assembly 5b is level with the top of the first conveying assembly 5a and the top of the first conveying assembly 5a.

[0050] In this embodiment, it should be noted that the stacking platform for stacking silicon steel sheets is placed on top of the third conveying assembly 503 on the top of the base 701. After the silicon steel sheets are stacked and fixed, the RGV trolley 1 can be controlled to move to align with the workbench 7 on which the stacking platform is placed. Then, the electric push rod 402 corresponding to the workbench 7 is controlled to run according to the orientation of the workbench 7.

[0051] The electric push rod 402 can push the movable seat 403, the fixed side plate 404, the rotating arm 405, and the fixed gear 407 to move synchronously towards the worktable 7. Since the bottom of the fixed gear 407 meshes with the rack 408, the fixed gear 407 will rotate during the movement. The rotating arm 405 of the fixed gear 407 rotates, causing the rotating arm 405 to rotate from a vertical state to a horizontal state. As the rotating arm 405 moves and rotates, the linkage gear 406 can approach the first driven gear 702 and eventually mesh with the first driven gear 702.

[0052] At this time, the first conveying component 5a, the second conveying component 5b, and the third component 5c are in a state of mutual linkage. When one of the conveying rollers 501 in the first conveying component 5a rotates, the multiple conveying rollers 501 in the first conveying component 5a, the second conveying component 5b, and the third component 5c rotate synchronously and in the same direction. At this time, the stacking table on the top of the workbench 7 can be transferred to the top of the RGV trolley 1, and then moved to the workbench 7 of other workstations by the RGV trolley 1. The same operation can be performed to transfer the stacking table to other workbench 7.

[0053] By combining the above components, the workbench 7 can be made to eliminate the need for a drive motor, which can effectively reduce equipment and maintenance costs, while still maintaining good ease of transfer of the stacking table.

[0054] Please refer to this carefully. Figures 1 to 4 A telescopic transmission assembly 6 is provided between the top support plate 2 and the fixed side plate 404 to provide driving force for the first conveying assembly 5a, the second conveying assembly 5b, and the third conveying assembly 5c.

[0055] The telescopic transmission assembly 6 includes a drive gear 601, a first moving gear 602, a second moving gear 603, and a linkage toothed belt 604;

[0056] The drive gear 601 is rotatably connected to both sides of the top support plate 2. The first moving gear 602 and the second moving gear 603 are located on the outside of the top support plate 2 and are rotatably connected to the fixed side plate 404 through the connecting shaft. The first moving gear 602 is rotatably connected to the fixed side plate 404. The connecting shaft of the second moving gear 603 passes through the fixed side plate 404 and is connected to another conveying roller 501 in the first conveying assembly 5a. The drive gear 601, the first moving gear 602, and the second moving gear 603 are staggered from bottom to top.

[0057] Two sets of drive gear 601, first moving gear 602, and second moving gear 603 are provided and are symmetrically distributed. The linkage toothed belt 604 is S-shaped and sleeved on the outside of the two sets of drive gear 601, first moving gear 602, and second moving gear 603 to realize the linkage of the two sets of first conveying components 5a in the two sets of extension components 4.

[0058] A limiting groove 605 is provided at the contact position between the top support plate 2 and the connecting shaft of the first moving gear 602 and the second moving gear 603, which is used to provide space for the movement of the connecting shaft when the first moving gear 602 and the second moving gear 603 move horizontally;

[0059] The top of the RGV trolley 1 is equipped with a dual-axis motor 606. The two output ends of the dual-axis motor 606 pass through the two top support plates 2 and are connected to two of the drive gears 601 in a set of drive gears 601.

[0060] The travel length of the connecting shaft between the first moving gear 602 and the second moving gear 603 inside the limiting slide groove 605 matches the semi-circular trajectory length of the fixed gear 407.

[0061] In this embodiment: when the electric push rod 402 drives the movable seat 403 to move, its first movable gear 602 and second movable gear 603 will move synchronously with the fixed side plate 404, and the linkage toothed belt 604 will deform synchronously. In this way, the first movable gear 602, the second movable gear 603 and the drive gear 601 can maintain normal transmission during the telescopic movement of the movable seat 403.

[0062] When the linkage gear 406 meshes with the first driven gear 702, the dual-shaft motor 606 can be started to move. The motor 606 drives the drive gear 601 to rotate. The drive gear 601 drives the first moving gear 602 and the second moving gear 603 to rotate through the linkage belt 604. The second moving gear 603 can drive one of the conveying rollers 501 in the first conveying assembly 5a to rotate. This conveying roller 501 can drive the other conveying rollers 501 in the first conveying assembly 5a and the second conveying assembly 5b to rotate synchronously through the transmission gear 502 and the transmission belt 503. One of the conveying rollers 501 in the second conveying assembly 5b drives the linkage gear 406 to rotate. The linkage gear 406 can drive the conveying roller 501 in the third conveying assembly 5c to rotate through the transmission of the first driven gear 702 and the second driven gear 703. In this way, the synchronous operation of the three conveying assemblies is realized, and the rotation direction of all the conveying rollers 501 in the three conveying assemblies is in the same direction, thereby realizing the transfer operation of the stacking table.

[0063] Please refer to this carefully. Figures 5 to 6 The L-shaped limiting plate 409 is symmetrically fixed to the outer wall of the two fixed side plates 404 and fits against the outer wall of the rotating arm 405. It is used to limit the rotating arm 405 in the vertical state and to support the rotating arm 405 in the horizontal state.

[0064] In this embodiment: when the rotating arm 405 rotates to a horizontal state, its bottom is in contact with the top of the horizontal part of the L-shaped limiting plate 409, so that the L-shaped limiting plate 409 can provide support for the rotating arm 405. When the rotating arm 405 rotates to a vertical state, the side of the rotating arm 405 is in contact with the side of the vertical part of the L-shaped limiting plate 409, so that the vertical rotation of the rotating arm 405 can be limited.

[0065] Please refer to this carefully. Figures 1 to 4The number of fixed rotating rods 3 is set to be multiple, and the multiple fixed rotating rods 3 are evenly distributed between the two top support plates 2 and located between the two sets of extension components 4.

[0066] In this embodiment: the fixed rotating rod 3 can provide support for the stacking platform. It should be noted that the distribution spacing of the fixed rotating rod 3 is less than the length of the stacking platform. When the stacking platform is moved above the RGV trolley, the bottom of the stacking platform is in contact with the two sets of first conveying components 5a and the fixed rotating rod 3.

[0067] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
