AGV transfer device for iron core storage

Abstract

This utility model discloses an AGV transfer device for iron core storage, including an AGV mobile platform. The AGV mobile platform has a transfer box with an upper opening for placing the transformer iron core. Multiple clamping plates are symmetrically arranged around the inner wall of the transfer box. A moving component is provided between each clamping plate and the transfer box to move the clamping plate closer to or away from one side of the inner wall of the transfer box. A vibration damping component is provided between the AGV mobile platform and the transfer box to reduce the vertical swaying arc of the transfer box. Through the symmetrically arranged clamping plates and moving components, the clamping position can be adaptively adjusted according to the shape characteristics of the iron core, ensuring uniform distribution of clamping force and avoiding localized stress concentration caused by mismatched contact surfaces in traditional general-purpose clamps. This effectively prevents the iron core from slipping or bumping during transportation. The vibration damping component reduces the impact of vibration on the iron core lamination structure during transportation by suppressing the vertical swaying amplitude of the transfer box, reducing the risk of iron core deformation or edge damage caused by mechanical vibration.

Description

Technical Field

[0001] This utility model relates to the field of iron core transfer technology, specifically to an AGV transfer device for iron core storage. Background Technology

[0002] As the core component of power equipment such as transformers and reactors, the iron core has stringent manufacturing requirements and its individual weight usually reaches more than 500 kg, with some large iron cores even exceeding 2 tons.

[0003] With the rapid development of intelligent manufacturing technology, Automated Guided Vehicles (AGVs), as core equipment for industrial logistics automation, have been widely used in material handling, warehouse management, and other fields. In the power equipment manufacturing industry, iron cores are core components of transformers and motors, and their transportation efficiency and safety directly affect the overall operation of the production line. Traditional iron core transportation mainly relies on manually operated forklifts or general-purpose AGV platforms. However, with the expansion of production scale and the increase in precision requirements, the existing transportation methods have gradually revealed their insufficient adaptability.

[0004] Currently, conventional AGV transfer devices mostly use standardized cargo platforms, securing materials with simple baffles or universal clamps. However, in the scenario of transporting iron cores, this structure has significant limitations. As a high-precision laminated assembly, the iron core has a regular shape but fragile edges. Universal clamps are difficult to conform to its surface characteristics, resulting in uneven clamping force distribution. This makes it prone to slippage and up-and-down jolting during transport, leading to damage to the iron core. Therefore, there is an urgent need for a device that can prevent the iron core from moving during transport to solve this problem. Utility Model Content

[0005] The main purpose of this utility model is to provide an AGV transfer device for iron core storage, which aims to solve the technical problem in the prior art that iron cores are prone to slippage or even tipping over during transportation vibration, resulting in damage to the iron cores.

[0006] To achieve the above objectives, the present invention proposes an AGV transfer device for iron core storage, comprising an AGV mobile platform, wherein the AGV mobile platform is provided with a transfer box with an upper opening for placing transformer iron cores, and multiple clamping plates are symmetrically arranged around the inner wall of the transfer box. Each clamping plate is provided with a moving component between it and the transfer box for moving the clamping plate closer to or away from one side of the inner wall of the transfer box. A vibration damping component is provided between the AGV mobile platform and the transfer box for reducing the vertical swaying arc of the transfer box.

[0007] Preferably, the moving component includes a first lead screw, one end of which is rotatably connected to the side of the clamping plate near the transfer box and extends out of the transfer box, and the other end passes through the transfer box and is movably connected to the transfer box. The extension direction of the first lead screw is in the same direction as the extension direction of the bottom wall of the transfer box. The moving component also includes a rotating component for driving the lead screw to rotate.

[0008] Preferably, the moving component includes a second lead screw and a bracket. The second lead screw meshes with the first lead screw. One end of the second lead screw is rotatably connected to the transfer box via a first rotating shaft, and the other end is rotatably connected to the bracket via a second rotating shaft. A first pulley is sleeved on the second rotating shaft. The moving component also includes a motor mounted on the bracket. A second pulley is mounted on the output shaft of the motor. The first pulley and the second pulley are connected by a plate drive belt. The moving component also includes a fixing component for limiting the rotation of the second lead screw.

[0009] Preferably, the fixing component includes a gear sleeved on the second rotating shaft, and also includes an electric telescopic rod mounted on the bracket. The output end of the electric telescopic rod is provided with a pin, and the output shaft of the electric telescopic rod extends out to drive the pin to be inserted into the tooth groove on the gear.

[0010] Preferably, a pressure sensor is provided on the side of the clamp plate away from the inner wall of the transfer box.

[0012] Preferably, a plurality of guides are provided between the clamping plate and the inner wall of the transfer box to restrict the movement direction of the clamping plate.

[0013] Preferably, the vibration damping component includes a sleeve vertically mounted on the AGV mobile platform with an open top. A column is slidably mounted inside the sleeve. One end of the column away from the sleeve is connected to the lower side of the transfer box. A first electromagnet is provided at the bottom of the sleeve. A second electromagnet is provided at the end of the column located inside the sleeve. A conductive ring is provided around the inner wall of the sleeve. Conductive brushes for contacting the conductive ring are provided on both sides of the second electromagnet.

[0014] In the technical solution of this utility model, multiple clamping plates and moving components arranged symmetrically around the core can adaptively adjust the clamping position according to the shape characteristics of the core, ensuring uniform distribution of clamping force and avoiding local stress concentration caused by mismatch of contact surfaces in traditional general-purpose clamps. This effectively prevents the core from slipping or bumping during transportation. The vibration damping component reduces the impact of vibration on the core lamination structure during transportation by suppressing the up-and-down shaking amplitude of the transfer box, thereby reducing the risk of core deformation or edge damage caused by mechanical vibration and greatly improving the quality of the transformer core.

[0028] This utility model proposes an AGV transfer device for iron core storage.

[0029] Please refer to Figures 1 to 4 The AGV transfer device for storing iron cores includes an AGV mobile platform 1. The AGV mobile platform 1 is provided with a transfer box 2 with an upper opening for placing transformer iron cores. Multiple clamping plates 3 are symmetrically arranged around the inner wall of the transfer box 2. A moving component 4 is provided between each clamping plate 3 and the transfer box 2 to move the clamping plate 3 closer to or away from one side of the inner wall of the transfer box 2. A vibration damping component 5 is provided between the AGV mobile platform 1 and the transfer box 2 to reduce the vertical swaying arc of the transfer box 2.

[0030] In the technical solution of this utility model, multiple clamping plates 3 and moving components 4 arranged symmetrically around the core can adaptively adjust the clamping position according to the shape characteristics of the core, ensuring uniform distribution of clamping force and avoiding local stress concentration caused by mismatch of contact surfaces in traditional general-purpose clamps. This effectively prevents the core from slipping or bumping during transportation. The vibration damping component 5 reduces the impact of vibration on the core lamination structure during transportation by suppressing the up-and-down shaking amplitude of the transfer box 2, thereby reducing the risk of core deformation or edge damage caused by mechanical vibration and greatly improving the quality of the transformer core.

[0031] Please refer to the appendix. Figure 1-2 The moving component 4 includes a first lead screw 41, one end of which is rotatably connected to the side of the clamping plate 3 near the transfer box 2 and extends out of the transfer box 2, and the other end passes through the transfer box 2 and is movably connected to the transfer box 2. The extension direction of the first lead screw 41 is the same as the extension direction of the bottom wall of the transfer box 2. The moving component 4 also includes a rotating component for driving the lead screw to rotate.

[0032] The first lead screw 41 is used in conjunction with the rotating component to achieve precise control of the linear movement of the clamping plate 3. The clamping distance can be finely adjusted according to the size of the iron core to avoid displacement or damage to the iron core caused by excessively loose or tight clamping. The lead screw drive has a self-locking characteristic, which can automatically maintain the position of the clamping plate 3 after adjustment to the correct position, preventing the clamping from loosening due to vibration during transportation.

[0033] Please refer to the appendix. Figure 2 The moving component 4 includes a second lead screw 42 and a bracket 46. The second lead screw 42 meshes with the first lead screw 41. One end of the second lead screw 42 is rotatably connected to the transfer box 2 via a first rotating shaft 43, and the other end is rotatably connected to the bracket 46 via a second rotating shaft 44. A first pulley 45 is sleeved on the second rotating shaft 44. The moving component 4 also includes a motor 48 mounted on the bracket 46. A second pulley 47 is mounted on the output shaft of the motor 48. The first pulley 45 and the second pulley 47 are connected by a plate drive belt 49. The moving component 4 also includes a fixing component for limiting the rotation of the second lead screw 42.

[0034] By engaging the second lead screw 42 with the first lead screw 41 and cooperating with the belt pulley transmission system, multiple motors 48 of multiple moving components 4 are controlled simultaneously to achieve synchronous movement of multiple clamping plates 3, ensuring the symmetry and uniformity of clamping force and avoiding the risk of core tilting caused by unilateral pressure.

[0035] Please refer to the appendix. Figure 2The fixing component includes a gear 412 sleeved on the second rotating shaft 44, and an electric telescopic rod 410 set on the bracket 46. The output end of the electric telescopic rod 410 is provided with a pin 411. The output shaft of the electric telescopic rod 410 extends out to drive the pin 411 to be inserted into the tooth groove on the gear 412.

[0036] The mechanical locking of the pin 411 and the tooth groove of the gear 412 completely fixes the rotational freedom of the second lead screw 42, preventing clamping loosening caused by external vibration or load changes and ensuring clamping stability throughout the transportation process; the electric telescopic rod 410 is linked with the control system and can automatically trigger the locking action after clamping is completed, without manual intervention, thus improving operating efficiency.

[0037] Please refer to the appendix. Figure 1 A pressure sensor is provided on the side of the clamping plate 3 that is away from the inner wall of the transfer box 2.

[0038] The pressure sensor is electrically connected to the moving component 4 through the PLC controller. The pressure sensor can provide real-time feedback on the pressure data applied by the clamping plate 3 to the iron core. Combined with the control system, the clamping force can be dynamically adjusted to avoid wear of the iron core coating or deformation of the internal laminations due to overpressure.

[0039] Please refer to the appendix. Figure 1 The clamping plate 3 is provided with protective pads on the side near the inner wall of the transfer box 2 and the bottom wall of the transfer box 2, respectively, for protecting the coating on the outer wall of the iron core.

[0040] The protective padding layer is made of flexible materials (such as rubber or polyurethane), which can buffer the impact force when the clamp 3 comes into contact with the iron core, and also prevent the hard clamps from scratching the coating on the surface of the iron core, thus protecting the appearance quality and insulation performance of the iron core.

[0041] Please refer to the appendix. Figure 1 Multiple guides are provided between the clamping plate 3 and the inner wall of the transfer box 2 to restrict the movement direction of the clamping plate 3.

[0042] Guide components (such as slide rails or guide posts) restrict the clamping plate 3 to move only in a preset direction, preventing the clamping plate 3 from shifting due to lead screw transmission errors or external loads, ensuring that the clamping center is aligned with the center of gravity of the iron core, and the guide components share the lateral force when the clamping plate 3 moves, reducing the frictional loss between the lead screw and the nut, and extending the service life of the transmission components.

[0043] Please refer to the appendix. Figure 3-4The vibration damping component 5 includes a sleeve 51 that is vertically mounted on the AGV mobile platform 1 and has an open top. A column 52 is slidably mounted inside the sleeve 51. One end of the column 52 away from the sleeve 51 is connected to the lower side of the transfer box 2. A first electromagnet 53 is provided at the bottom of the sleeve 51. A second electromagnet 54 is provided at one end of the column 52 located inside the sleeve 51. A conductive ring 56 is arranged around the inner wall of the sleeve 51. Conductive brushes 55 are provided on both sides of the second electromagnet 54 for contacting the conductive ring 56.

[0044] Both the column 52 and the sleeve 51 are made of non-magnetic materials to prevent the magnetic field generated by the first electromagnet 53 and the second electromagnet 54 from affecting the sliding of the column 52 in the sleeve 51.

[0045] Different weight transformer cores have different requirements for vibration damping. After the transformer core is placed in the transfer box 2, the first electromagnet 53 and the second electromagnet 54 are energized and the current is gradually increased so that the first electromagnet 53 and the second electromagnet 54 generate a repulsive magnetic field. This further causes the column 52 to move away from the sleeve 51 until the conductive brush 55 contacts the conductive ring 56. At this time, the current of the first electromagnet 53 and the second electromagnet 54 stops increasing and maintains the existing current so that the column 52 floats and slides in the sleeve 51. Because different weight transformer cores require different forces to make the conductive brush 55 contact the conductive ring 56 (the repulsive force between the first electromagnet 53 and the second electromagnet 54, and the different current and voltage of the first electromagnet 53 and the second electromagnet 54), the vibration damping assembly can dampen transformers of different weights.

[0046] The vibration damping intensity is dynamically adjusted by the magnetic repulsion between the first electromagnet 53 and the second electromagnet 54. Compared with traditional spring or hydraulic vibration damping, the response speed is faster, and the optimal vibration damping parameters can be automatically adapted according to the load weight. Non-contact electromagnetic vibration damping reduces mechanical wear and lowers the frequency and cost of device maintenance.

[0047] The specific operation of this utility model is as follows: The transformer core is hoisted into the transfer box 2 by the hoisting device. The motor 48 rotates to drive the second lead screw 42 to rotate under the cooperation of the first pulley 45, the second pulley 47 and the transmission belt 49. The rotation of the second lead screw 42 drives the first lead screw 41 to rotate. The rotation of the first lead screw 41 drives the clamping plate 3 to move towards the side closer to the transformer core. After the pressure sensor detects that the pressure is greater than the threshold, the motor 48 stops working. At the same time, the output shaft of the electric telescopic rod 410 extends so that the pin 411 is inserted into the tooth groove of the gear 412 to fix the position of the clamping plate 3 and complete the fixation of the position of the transformer core in the transfer box 2.

[0048] The first electromagnet 53 and the second electromagnet 54 are energized and the current is gradually increased so that the first electromagnet 53 and the second electromagnet 54 generate a repulsive magnetic field, which further moves the column 52 away from the sleeve 51 until the conductive brush 55 contacts the conductive ring 56. At this time, the current of the first electromagnet 53 and the second electromagnet 54 stops increasing and maintains the existing current, so that the column 52 floats and slides inside the sleeve 51.

[0049] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
