[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] During the fabrication of a three-dimensional iron core, corresponding debris will be generated and adsorbed onto the core. As an important process in iron core manufacturing, the assembly of debris directly affects the manufacturing and performance of the transformer. However, the current debris cleaning relies entirely on manual labor, with air blowing cleaning performed before assembly. This operation is cumbersome and has a low degree of automation, making it impossible for the production line to operate efficiently. Utility Model Content

[0030] This utility model embodiment provides a three-dimensional coiled iron core fragment cleaning device. Figure 1 This is a perspective view of a three-dimensional coiled iron core fragment cleaning device according to an embodiment of the present invention. (Reference) Figure 1 As shown, the device includes at least:

[0031] The machine base 1 includes a central disk 101 located at the center, and crossbeams 102 of the same number as the single frame of the three-dimensional coiled iron core are evenly arranged along the outer circumference of the central disk 101. A column 103 extending downward is provided at the end of each crossbeam 102. A drive mechanism 2 is installed on the crossbeam 102, and a clamping station 3 is installed below the drive mechanism 2. The drive mechanism 2 is used to drive the clamping station 3 to slide on the crossbeam 102. The clamping station 3 is provided with a longitudinally expanding and contracting tensioning mechanism 304. A cleaning device 4 for blowing air to the clamping station 3 is provided on the lower side of the connection between the crossbeam 102 and the central disk 101.

[0032] Furthermore, the base 1 adopts a gantry frame design, with the gantry frame set at a 120° angle, forming a triangular gantry frame. This structure features high stability and load-bearing capacity, providing a solid and reliable support foundation for the entire debris removal device.

[0033] Furthermore, three clamping stations 3 are set on the gantry. This layout enables the device to perform debris cleaning operations on multiple areas or multiple targets simultaneously, greatly improving cleaning efficiency and meeting the needs of large-scale, multi-task cleaning.

[0034] Furthermore, each clamping station 3 has independent forward and backward functions, and the drive mechanism 2 performs a reciprocating motion after reaching the designated cleaning position. This reciprocating motion is designed to achieve a more thorough cleaning effect. Through this motion, the cleaning device 4 can more effectively remove debris and impurities from the surface of the iron core, improving the cleaning quality.

[0035] Furthermore, each clamping station 3 is equipped with a corresponding cleaning device 4, which can comprehensively cover the iron core, achieving 360° cleaning of the iron core surface without dead angles. This effectively removes debris from the iron core surface, ensuring optimal performance of the iron core during subsequent processing and assembly. In addition, this comprehensive cleaning method can improve production efficiency, reduce rework and scrap rates caused by surface quality issues, and improve the overall efficiency of the production process.

[0036] Furthermore, the tensioning mechanism 304 includes two longitudinally symmetrically arranged tensioning structures, which move up and down towards or away from each other.

[0037] The tensioning mechanism 304 can perform precise gripping operations according to different models of coiled iron cores. The tensioning mechanism 304 can firmly grip the coiled iron core, ensuring that there will be no slippage or positional deviation during the material receiving process.

[0038] In some embodiments, the clamping station 3 further includes a mounting bracket 301, a rotary mechanism 303, and a rotary drive 302. The mounting bracket 301 is mounted on the bottom of the rotary mechanism 303, and the rotary drive 302 is connected to the rotary mechanism 303. The rotary drive 302 drives the rotary mechanism 303 to rotate the mounting bracket 301.

[0039] Furthermore, the rotary drive 302 is driven by a first servo motor, one end of which is connected to a drive gear. The rotary mechanism 303 is a ring gear, and the drive gear meshes with the ring gear. After the first servo motor starts, the drive gear of the rotary drive 302 drives the ring gear of the rotary mechanism 303 to rotate the mounting bracket 301.

[0040] The rotary drive 302 and the rotary mechanism 303 are connected by gears for power transmission. This gear connection structure not only ensures the stability and accuracy of power transmission, but also has high transmission efficiency. When the rotary drive 302 is started, the meshing of the gears drives the rotary mechanism 303 to achieve precise rotary motion.

[0041] In some embodiments, a lifting mechanism 6 is installed on one side of the column 103. The lifting mechanism 6 includes a lifting drive 601 and a lifting platform 602. The lifting drive 601 drives the lifting platform 602 to move up and down.

[0042] Furthermore, the lifting platform 602 is provided with a positioning groove, the shape and size of which are adapted to the coiled iron core, so that the iron core can be placed vertically and the tensioning mechanism 304 of the clamping station 3 can clamp it.

[0043] In some embodiments, a moving mechanism 603 is installed at the lower end of the lifting drive 601, and the moving mechanism 603 drives the lifting drive 601 to slide horizontally.

[0044] The lifting mechanism 6 includes a lifting structure and a lateral moving structure, which can meet various complex material positioning requirements. The lifting drive 601 can precisely adjust the height of the lifting mechanism 6 according to the height of different materials and the specific position of the clamping station 3; the moving mechanism 603 enables the lifting mechanism 6 to not only be adjusted up and down, but also to move in the horizontal direction, flexibly adjusting its position in the horizontal direction.

[0045] In some embodiments, the lifting drive 601 is a piston telescopic device, and the piston rod of the lifting drive 601 drives the lifting platform 602 to move freely up and down.

[0046] 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.

[0047] In some embodiments, the cleaning device 4 includes a frame 401 and an air blowing device 402, which is fixed to the frame 401.

[0048] Furthermore, the frame 401 can be rectangular, circular, or other shapes that can achieve the cleaning function. When the frame 401 is rectangular, it is provided with groups of air blowing devices 402 at the top and bottom and groups of air blowing devices 402 at the left and right.

[0049] After the clamping station 3 reaches the cleaning position, it reciprocates under the drive of the drive mechanism 2. The air blowing device 402 blows air onto the clamping station 3 that is reciprocating. The air blowing device 402 can wrap the iron core in all directions, thereby achieving 360° cleaning of the iron core surface without dead angles, and can effectively remove debris from the iron core surface.

[0050] In some embodiments, the drive mechanism 2 includes a slider 201, a lead screw 203, a moving drive 202, a guide rail 204, and a fixed bracket 205. A guide rail 204 aligned with the direction of the crossbeam 102 is provided below the crossbeam 102. A slider 201 is provided on the lower side of the guide rail 204, and a fixed bracket 205 is provided on the lower side of the slider 201. The slider 201 is connected to the lead screw 203, and the lead screw 203 is connected to the moving drive 202. The moving drive 202 drives the lead screw 203 to move the slider 201 on the guide rail 204.

[0051] Furthermore, the motion drive 202 is driven by a second servo motor, which drives the lead screw 203 to rotate, and the lead screw 203 drives the slider 201 to move along the guide rail 204.

[0052] In some embodiments, a feeding mechanism 5 is also included, which has the same structure as the clamping station 3.

[0053] In some embodiments, a feeding table 7 is also included, on which the feeding mechanism 5 slides in a direction close to or away from the clamping station 3.

[0054] Furthermore, the feeding mechanism 5 is capable of movement and rotation.

[0055] In some embodiments, the tensioning mechanism 304 is configured as a piston telescopic device, and the tensioning mechanism 304 is driven by the piston rod of the piston telescopic device to move freely up and down.

[0056] 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.

[0057] During use, select the corresponding core specification and model on the system interface according to the required core specifications to be cleaned, and press the equipment start button. The clamping station 3 on the drive mechanism 2 rotates to the outside under the drive of the rotary drive 302, as... Figure 4 .

[0058] The receiving mechanism 5 removes a single iron core from the iron core storage and transports it to the lifting mechanism 6. The two tensioning structures of the tensioning mechanism 304 of the receiving mechanism 5 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 return to the iron core storage to retrieve the next iron core. The lifting mechanism 6 lifts and moves laterally to align with the clamping station 3. Based on the required iron core specifications, the two tensioning structures of the tensioning mechanism 304 of the clamping station 3 move away from each other a corresponding distance, tightening the upper and lower end faces of the inner frame of the iron core. The rotating mechanism 303 rotates 90° in the opposite direction to complete the material retrieval action, and the remaining clamping stations 3 complete the material receiving in sequence, such as... Figure 5 .

[0059] After all the assembly mechanisms have rotated to the inner side, the drive mechanism 2 drives the clamping station 3 to converge towards the center at the same time. The cleaning device 4 is started. After the drive mechanism 2 reaches the cleaning position, it reciprocates. After the action is completed, it returns to the original point. The rotary mechanism 303 rotates 90° in the forward direction. After the cleaned iron core is placed on the lifting mechanism 6, the two tensioning structures of the tensioning mechanism 304 of the clamping station 3 move towards each other by a corresponding distance. The two tensioning structures move away from the upper and lower end faces of the inner frame of the iron core, waiting for the next iron core cleaning instruction.

[0060] 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.

[0061] 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.
