[0002] The three-dimensional wound core transformer is a type of transformer that breaks through the traditional planar core structure. The core is composed of three single-frame structures assembled from several trapezoidal strips wound sequentially, forming a three-phase symmetrical three-dimensional structure. Compared with traditional transformer cores, it features three-phase balance, material saving, low no-load loss, low no-load current, strong short-circuit withstand capability, low noise, and low electric and magnetic fields.

[0003] In the preparation of three-dimensional iron cores, core assembly is a crucial process.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-5 As shown in the schematic embodiment of the three-dimensional coiled iron core automatic assembly device of this utility model, the three-dimensional coiled iron core automatic assembly device includes a base 1, and an assembly rotary mechanism 2 is rotatably connected to the base 1. The rotation axis of the assembly rotary mechanism 2 is vertical. An assembly mechanism 3 is installed on the top of the assembly rotary mechanism 2. The assembly mechanism 3 includes a first moving mechanism 306, a second rotating mechanism 303, and a mounting bracket 302. The first moving mechanism 306 is installed on the assembly rotary mechanism 2, the second rotating mechanism 303 is installed on the first moving mechanism 306, and the mounting bracket 302 is installed on the second rotating mechanism 303. The first moving mechanism 306 slides radially on the assembly rotary mechanism 2, the second rotating mechanism 303 rotates around the vertical rotation axis, and a longitudinally expanding and contracting tensioning mechanism 301 is provided on the mounting bracket 302.

[0023] Furthermore, the number of assembly mechanisms 3 on the assembly rotation mechanism 2 is the same as the number of single frames of the three-dimensional coiled iron core, and the assembly mechanisms 3 are arranged at equal intervals along the circumference.

[0024] Furthermore, the tensioning mechanism 301 includes two longitudinally symmetrically arranged tensioning structures, which move up and down towards or away from each other.

[0025] In actual operation, the operator can issue instructions through the control system, and the assembly slewing mechanism 2 will rotate in the forward or reverse direction according to the preset program to complete the material docking work.

[0026] Each assembly mechanism 3 has independent forward, backward, and forward / reverse rotation functions. This design allows each assembly mechanism 3 to flexibly adjust its position and angle according to specific assembly requirements, enabling parallel operation and significantly saving time.

[0027] After the assembly mechanism 3 receives the iron core to be assembled, the tensioning mechanism 301 can flexibly adapt to iron cores of different specifications. Whether the iron core is large or small, it can achieve effective tensioning, ensuring the stability and accuracy of the assembly process.

[0028] In some embodiments, the assembly rotary mechanism 2 includes a first rotary mechanism 201, a first rotary drive 202, and a rotary table 203. The top of the first rotary mechanism 201 is fixedly connected to the rotary table 203, and the first rotary mechanism 201 is rotatably connected to the first rotary drive 202. The first rotary drive 202 drives the first rotary mechanism 201 to drive the rotary table 203 to rotate.

[0029] Furthermore, the first rotary drive 202 is driven by a first servo motor, one end of which is connected to a first drive gear. The first rotary mechanism 201 is a first ring gear, and the first drive gear meshes with the first ring gear. After the first servo motor is started, the first drive gear of the first rotary drive 202 drives the first ring gear of the first rotary mechanism 201 to rotate the rotary table 203.

[0030] The assembly rotary mechanism 2 is structurally stable and durable. Its rotary structure employs gear transmission and servo motor drive, ensuring smooth operation and precise positioning during rotation in both positive and negative directions. This rotary capability allows the device to adapt to various production processes and layout requirements, especially in production environments that require frequent changes in work positions or collaboration with multiple upstream devices.

[0031] In some embodiments, a lifting mechanism 4 is provided at the internal center of the assembly rotary mechanism 2. The lifting mechanism 4 includes a lifting drive 401 and a lifting platform 402. The lifting drive 401 drives the lifting platform 402 to move up and down.

[0032] After the iron core is assembled on the assembly mechanism 3 of the assembly rotary mechanism 2, the lifting platform 402 rises smoothly under the drive of the lifting drive 401, accurately supporting the bottom of the iron core. This not only provides stable support for the assembled iron core, but also creates convenient conditions for the robotic arm or other gripping equipment in the next process, ensuring a seamless connection in the production process.

[0033] In some embodiments, the lifting drive 401 is a piston telescopic device, and the lifting platform 402 is driven by the piston rod of the piston telescopic device to move freely up and down.

[0034] Furthermore, the piston telescopic device can be a hydraulic piston telescopic device, which uses the pressure of hydraulic oil to push the piston rod to achieve telescopic movement; it can also be a pneumatic piston telescopic device, which relies on compressed air to drive the piston movement; or it can be an electric screw-driven piston telescopic device, which uses a motor to drive the screw to rotate, causing the piston rod on the nut to move linearly, with high precision and controllability.

[0035] In some embodiments, the first moving mechanism 306 is connected to the first moving drive 304, and the first moving drive 304 drives the first moving mechanism 306 to move the mounting bracket 302.

[0036] Furthermore, the first moving mechanism 306 includes a slide rail, a slider, and a lead screw; the slider is mounted on the slide rail and connected to the lead screw; Furthermore, the first motion drive 304 is driven by a second servo motor, which drives the lead screw to rotate, and the lead screw drives the slider to move along the slide rail direction.

[0037] In some embodiments, the second rotary mechanism 303 is connected to the second rotary drive 305, and the second rotary drive 305 drives the second rotary mechanism 303 to rotate the mounting bracket 302.

[0038] Furthermore, the second rotary drive 305 is driven by a third servo motor, one end of which is connected to the second drive gear.

[0039] Furthermore, the second rotating mechanism 303 is a second ring gear, and the second drive gear meshes with the second ring gear.

[0040] After the servo motor is started, the second drive gear of the second rotary drive 305 drives the second ring gear of the second rotary mechanism 303 to rotate the mounting bracket 302 mounted on the second rotary mechanism 303.

[0041] In some embodiments, a visual inspection device 5 is fixed at the center vertically upward position of the assembly rotation mechanism 2.

[0042] The visual inspection device 5 can monitor the assembly status in real time during the core assembly process. The visual inspection device 5 captures image data during the assembly process using a high-precision camera, and uses image processing software to analyze key parameters such as the size, position, and angle of the core to ensure that it meets the preset standards and size requirements.

[0043] Once a deviation is detected during the assembly process, the system immediately sends a feedback signal to the rotary mechanism of the individual assembly mechanism 3. The rotary mechanism of the individual assembly mechanism 3 responds quickly based on the feedback from the vision system, adjusting the assembly angle of the iron core by rotating left and right to ensure that the final assembly size and quality meet the expected standards. This closed-loop control system not only improves the assembly accuracy but also enhances the automation and intelligence level of the entire device. Through the synergistic effect of vision inspection and the rotary mechanism, the device can effectively adapt to the assembly requirements of iron cores of different specifications, ensuring the stability and consistency of the production process, thereby significantly improving the quality and efficiency of iron core assembly.

[0044] In some embodiments, the three-dimensional coiled iron core automatic assembly device also includes a material receiving mechanism 6, which has the same structure as the assembly mechanism 3.

[0045] Furthermore, during the material receiving and unloading process, the tensioning mechanism 301 of assembly mechanism 3 and the tensioning mechanism 301 of material receiving mechanism 6 are aligned and connected, ensuring that materials can flow smoothly from material receiving mechanism 6 to assembly mechanism 3. This design not only improves the efficiency of material transfer but also enhances the stability and reliability of the entire production process, thereby ensuring the smooth operation of the material receiving and unloading process.

[0046] In some embodiments, the three-dimensional coiled iron core automatic assembly device also includes a material receiving table 7, on which the material receiving mechanism 6 slides in a direction close to or away from the assembly mechanism 3.

[0047] Furthermore, the feeding mechanism 6 can also move and rotate.

[0048] In some embodiments, the tensioning mechanism 301 is configured as a piston telescopic device, and the tensioning mechanism 301 is driven by the piston rod of the piston telescopic device to move freely up and down.

[0049] Furthermore, the piston telescopic device can be a hydraulic piston telescopic device, which uses the pressure of hydraulic oil to push the piston rod to achieve telescopic movement; it can also be a pneumatic piston telescopic device, which relies on compressed air to drive the piston movement; or it can be an electric screw-driven piston telescopic device, which uses a motor to drive the screw to rotate, causing the piston rod on the nut to move linearly, with high precision and controllability.

[0050] In use, the feeding mechanism 6 takes a single iron core out of the iron core warehouse and transports it to the receiving position. The feeding mechanism 6 is aligned with the assembly mechanism 3. According to the specifications of the iron core to be assembled, the two tensioning structures of the tensioning mechanism 301 in the assembly mechanism 3 move back and forth a corresponding distance, and the tensioning mechanism 301 tensions the upper and lower end faces of the inner frame of the iron core.

[0051] The two tensioning mechanisms 301 in the feeding mechanism 6 move towards each other a corresponding distance, moving away from the upper and lower end faces of the inner frame of the iron core and retracting into the iron core storage container to retrieve the next iron core; after the assembly mechanism 3 completes receiving the material, the assembly rotation mechanism 2 rotates, and the next assembly mechanism 3 docks with the next feeding mechanism 6 to complete receiving the material, until all receiving is completed, as follows. Figure 5 .

[0052] The second rotary drive 305 of the three assembly mechanisms 3 drives the second rotary mechanism 303 to rotate. After all the assembly mechanisms 3 have rotated to the inside, the first moving drive 304 drives the first moving mechanism 306 to converge towards the center at the same time and stop when they reach the pre-assembly position. The vision inspection device 5 starts to work and detects the iron core assembly triangle area. According to the data fed back by the vision system, the assembly mechanism 3 swings left and right appropriately to adjust the iron core angle. After passing the test, the three iron cores continue to move towards the center position for assembly. When they reach the assembly position, the drive device stops automatically.

[0053] The automatic winding device wraps fiberglass tape around the three iron core columns. After winding is completed, the lifting drive 401 pushes the lifting platform 402 to rise, supporting the bottom of the assembled iron core. The two tensioning structures of the tensioning mechanism 301 in the three assembly mechanisms 3 move towards each other by a corresponding distance, and the tensioning mechanism 301 moves away from the upper and lower end faces of the inner frame of the iron core, waiting for the next iron core assembly instruction.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
