However, the error range of traditional assembly processes can no longer meet these standards; the production capacity bottleneck of manual assembly is becoming increasingly prominent.

[0003] In the field of transformer core manufacturing, existing systems often suffer from limitations such as limited functionality and insufficient coordination. For example, traditional conveying devices can only achieve linear transport of workpieces, cannot precisely connect with assembly mechanisms, and are difficult to adapt to spatial posture adjustments during insulation paper splicing. Although some equipment is equipped with vision inspection modules, it can only identify the presence or absence of workpieces and cannot collect position coordinates in real time and feed them back to the control system, resulting in the accumulation of assembly errors.

[0045] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, the technical features involved in the various embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0046] Please see Figures 1-6 The transformer core rapid assembly system in the preferred embodiment of the present invention specifically includes a conveyor belt assembly 100, a jig assembly 200, a first assembly assembly 400, a first workbench 600, and a second workbench 700. The conveyor belt assembly 100 is arranged along the X-axis, while the jig assembly 200 is arranged on the conveyor belt assembly 100 to support the lower yoke 300 to be assembled. The first assembly assembly 400 spans the conveyor belt assembly 100 along the Y-axis. The first assembly assembly 400 includes two support structures 401, which are respectively arranged on the conveyor belt assembly 100 along the Y-axis. The first assembly assembly 400 is located on both sides of the first assembly assembly 400 in the Y-axis direction. An X-axis moving unit 402 is provided on the bracket 401, and a Y-axis moving module is provided between the two X-axis moving units 402. Two sliders are arranged at intervals along the X-axis direction on the Y-axis moving module. Each slider is provided with a Z-axis moving unit 404, and a gripper 405 is provided on the telescopic unit of the Z-axis moving module. The two grippers 405 move in opposite directions. The first worktable 600 and the second worktable 700 are respectively located on both sides of the first assembly assembly 400 in the Y-axis direction. The first worktable 600 and the second worktable 700 are used to place the insulating paper 601 and the winding structure 602 to be assembled, respectively. At the same time, a first detection camera 406 is provided below each slider to collect image data and position information of the lower yoke 300. When the gripper 405 moves with the X-axis moving unit 402, the Y-axis moving unit 403 and the Z-axis moving unit 404 to the top of the first worktable 600 or the second worktable 700, it collects image data and position information of the workpiece to be assembled on the worktable.

[0047] More specifically, the rapid assembly system in the preferred embodiment of the present invention further includes a second assembly component 500, which is straddling the conveyor belt assembly 100 along the Y-axis direction and spaced apart from the first assembly group in the X-axis direction; it includes a frame 501 and two first telescopic units 502, a second telescopic unit 503 and a third telescopic unit 504 located on opposite sides inside the frame 501; wherein, the first telescopic unit 502 is arranged along the Y-axis direction, the second telescopic unit 503 is arranged along the X-axis direction on the telescopic end of the first telescopic unit 502, and the third telescopic unit 504 is arranged on the movable end of the second telescopic unit 503.

[0048] Furthermore, a pressure block is also provided on the telescopic end of the third telescopic unit 504 to press the upper yoke onto the lower yoke 300. At the same time, a second detection camera 505 is also provided on the top of the inner cavity of the frame 501 to collect image data of the lower yoke 300 located at the bottom of the frame 501.

[0049] In actual use, the second assembly component 500 is spaced apart from the first assembly component 400. The first telescopic unit 502 of the Y-axis, the second telescopic unit 503 of the X-axis, and the third telescopic unit 504 of the Z-axis in the frame 501 work together to drive the pressing block. The second detection camera 505 at the top monitors the position of the lower yoke 300 in real time. Through multi-axis linkage, the upper yoke is precisely pressed to the lower yoke 300 to form a closed magnetic circuit, replacing the traditional manual pressing operation, ensuring that the air gap of the magnetic circuit is evenly distributed and improving the electromagnetic performance of the iron core.

[0050] More specifically, the jig assembly 200 includes a carrier plate 201 and a clamping structure 203; the clamping structure 203 is disposed on the linear module 202 for clamping and limiting the lower yoke 300. More preferably, the linear module 202 is disposed on the carrier plate 201 along the X-axis direction, and the clamping structure 203 is disposed on the linear module 202 for driving the linear module 202 to make fine adjustments along the X-axis direction.

[0051] Meanwhile, an infrared receiver is also installed on the carrier plate 201; correspondingly, an infrared transmitter is installed on the frame 501, which is communicatively connected to the infrared receiver and used to position the carrier plate 201. The fixture assembly 200, through the cooperation of the linear module 202 on the carrier plate 201 and the clamping structure 203, can adjust the clamping position according to the iron core specifications. Combined with the positioning calibration of the infrared receiver and the transmitter of the frame 501, it can achieve adaptive clamping and precise positioning of iron cores with different numbers of core columns, solve the problem of time-consuming changeover of traditional fixed fixtures, and enhance the flexible production capability of the production line.

[0052] In addition, the preferred embodiment of the present invention also includes a data processing module, which is communicatively connected to the first detection camera 406 and the second detection camera 505, respectively, for receiving image data collected by the first detection camera 406 and the second detection camera 505, and controlling the first assembly component 400, the second assembly component 500, and the conveyor belt component 100 to work together according to the image data acquisition location information.

[0053] In practical use, the conveyor belt assembly 100 is set along the X-axis, and the fixture assembly 200 is mounted on the conveyor belt. Its carrier plate 201 drives the clamping structure 203 to make fine adjustments along the X-axis through the linear module 202. With the communication positioning between the infrared receiver and the infrared transmitter of the frame 501, the lower yoke 300 is stably clamped and its position is calibrated, solving the offset problem caused by traditional manual handling and providing a precise benchmark for subsequent assembly. The first assembly assembly 400 is straddling both sides of the conveyor belt along the Y-axis. It forms a three-axis linkage structure through the X-axis moving unit on the bracket 401, the Y-axis moving module, and the Z-axis moving unit on the slider. The gripper 405 moves in the opposite direction under the drive of the slider to synchronously grab the workpiece. The first detection camera 406 under the slider collects image data of the lower yoke 300 and the workpiece on the worktable in real time. After the data processing module calculates the data, it controls the three-axis linkage to realize the precise splicing of the insulating paper 601 according to the number of core columns and the automated assembly of the winding. The robotic arm replaces manual operation, which significantly improves the assembly efficiency and consistency.

[0054] The data processing module, together with the first and second detection cameras 505, forms a closed-loop control system. It receives image data in real time and calculates the workpiece position information. It synchronously controls the conveyor belt assembly 100, the first assembly assembly 400, and the second assembly assembly 500 to work together. The entire process is automated, from the splicing of the insulating paper 601 and the assembly of the winding to the pressing of the upper yoke. This avoids the accumulation of human operation errors and improves the assembly accuracy and system stability.

[0055] Based on this, the present invention also provides a rapid assembly method for transformer cores, which utilizes the aforementioned rapid assembly system. The method includes the following steps: assembling the upper yoke of the core onto a jig assembly 200, and assembling the jig assembly 200 onto a conveyor belt assembly 100; the conveyor belt transports the jig assembly 200, carrying the lower yoke 300, to the position of the first assembly assembly 400; the first assembly assembly 400 drives the grippers 405 to move via an X-axis moving unit 402, a Y-axis moving unit 403, and a Z-axis moving unit 404, first gripping the insulating paper 601, then gripping a corresponding number of insulating papers 601 according to the number of vertical cores of the lower yoke 300, and attaching the insulators to the vertical cores of the lower yoke 300; next, adjusting the position of the lower yoke 300 in the X-axis direction, using the grippers 405 on the other side to grip a corresponding number of coil windings, and assembling them onto the vertical cores of the lower yoke 300; thus completing the assembly of the lower yoke 300.

[0056] The assembly method relies on the above system. First, the lower yoke 300 is fixed to the fixture and transported to the assembly station by the conveyor belt. The first assembly component 400 completes the connection of the insulating paper 601 and the winding assembly through the three-axis linkage gripper 405. Subsequently, the second assembly component 500 automatically presses the upper yoke. Each process achieves precise coordination through visual inspection and data processing, which simplifies the complex process of traditional manual assembly, reduces labor intensity, and significantly improves the efficiency and reliability of core assembly.

[0057] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
