Description

Technical Field

[0001] This utility model relates to the field of transformers, and specifically to a winding head mechanism for a transformer shaft winding device. Background Technology

[0002] In the manufacturing process of transformers, especially multi-strand transformers, the "heading" process after winding (i.e., properly fixing the wire ends to the bobbin pins) is a crucial step in ensuring the reliability of the product's electrical connections. Currently, the level of automation in this step is severely lagging behind, becoming a major bottleneck restricting the improvement of production efficiency and product quality.

[0003] Currently, the industry generally suffers from the following two outdated production methods:

[0004] 1. Purely Manual Operation Mode: Many small and medium-sized manufacturers still rely entirely on manual labor for thread trimming. Operators use simple tools such as tweezers and crochet hooks to manually press, wrap, or hook the thread ends onto the pins. This method has significant drawbacks: First, production efficiency is extremely low, as the speed of manual thread trimming cannot match the pace of automatic winding, becoming a bottleneck for the entire production line; second, the quality of the work is extremely unstable, entirely dependent on the operator's skill and work condition, easily leading to quality problems such as loose, crooked, or even damaged thread ends, making it impossible to guarantee product consistency.

[0005] 2. Semi-automated equipment mode: Some automated winding equipment attempts to integrate simple mechanical mechanisms (such as pressure bars with fixed stroke) to replace some manual labor. However, these mechanisms are often low in intelligence and rough in operation. Their core defects are: (1) poor adaptability: unable to accurately adapt to changes in different bobbin models and pin spacing; (2) high risk of damage: mechanical parts are prone to rigid collisions with the wound wire turns or pins during the pressing process, which may scratch the wire insulation layer or break the coil, thus introducing new quality hazards.

[0006] In conclusion, existing technologies, whether manual or rudimentary mechanical automation, cannot meet the modern manufacturing industry's demands for high efficiency, high consistency, and high reliability. The heavy reliance on manual labor in the "heading" process leads to a series of problems, including high production costs, large quality fluctuations, and limited production capacity.

[0007] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0008] The purpose of this utility model is to provide a winding head mechanism for a transformer shaft winding device to overcome the above-mentioned shortcomings and deficiencies of the prior art.

[0009] A winding mechanism for a transformer shaft includes: a robotic arm, an X-axis transmission system, a Y-axis transmission system, a Z-axis transmission system, a fixed guide pin module, and a guide pin. The robotic arm is connected to the X-axis transmission system, the Y-axis transmission system, and the Z-axis transmission system. The fixed guide pin module is connected to the robotic arm, and the bottom end of the fixed guide pin module is connected to the guide pin.

[0010] Furthermore, the X-axis transmission system includes: an X-axis transmission motor, an X-axis transmission screw, and an X-axis slide rail. The X-axis transmission motor is connected to the robotic arm via the X-axis transmission screw, the X-axis slide rail is connected to the robotic arm, and the X-axis transmission motor is connected to the Y-axis transmission system.

[0011] Furthermore, the Y-axis transmission system includes: a Y-axis transmission motor, a Y-axis slide rail, and a Y-axis lead screw. The Y-axis transmission motor drives the X-axis transmission motor to move along the Y-axis slide rail via the Y-axis lead screw.

[0012] Furthermore, the Z-axis transmission system includes: a Z-axis transmission motor, a Z-axis slide rail, and a Z-axis lead screw.

[0022] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] Example 1

[0024] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a diagram showing the usage state of this utility model.

[0025] like Figure 1-2 As shown, a winding mechanism for a transformer shaft winding device includes: a robotic arm 100, an X-axis transmission system 200, a Y-axis transmission system 300, a Z-axis transmission system 400, a fixed guide pin module 500, and a guide pin 600. The robotic arm 100 is connected to the X-axis transmission system 200, the Y-axis transmission system 300, and the Z-axis transmission system 400. The fixed guide pin module 500 is connected to the robotic arm 100, and the bottom end of the fixed guide pin module 500 is connected to the guide pin 600.

[0026] The X-axis transmission system 200 includes an X-axis transmission motor 210, an X-axis transmission screw 220, and an X-axis slide rail 230. The X-axis transmission motor 210 is connected to the robotic arm 100 through the X-axis transmission screw 220, the X-axis slide rail 230 is connected to the robotic arm 100, and the X-axis transmission motor 210 is connected to the Y-axis transmission system 300.

[0027] The Y-axis transmission system 300 includes a Y-axis transmission motor 310, a Y-axis slide rail 320, and a Y-axis lead screw 330. The Y-axis transmission motor 310 drives the X-axis transmission motor 210 to move on the Y-axis slide rail 320 through the Y-axis lead screw 330.

[0028] The Z-axis transmission system 400 includes a Z-axis transmission motor 410, a Z-axis slide rail 420, and a Z-axis lead screw 430. The Z-axis transmission motor 410 drives the X-axis transmission system 200 and the Y-axis transmission system 300 to move on the Z-axis slide rail 420 via the Z-axis lead screw 430.

[0029] The principle of this utility model is that the X-axis transmission system 200, Y-axis transmission system 300 and Z-axis transmission system 400 provide the power for movement and action, which is then transmitted in conjunction with the robotic arm 100, and the head is achieved through the fixed guide needle module 500 and guide needle 600.

[0030] Specifically, the X-axis transmission system 200 is directly connected to the robotic arm 100, essentially enabling the robotic arm 100 to move along the X-axis along the X-axis slide rail 230. Similarly, the X-axis transmission system 200 moves along the Y-axis via the Y-axis transmission system 300, thus allowing the robotic arm 100 to move in the Y-axis direction. Likewise, the X-axis transmission system 200 and the Y-axis transmission system 300 move along the Z-axis via the Z-axis transmission system 400, thus enabling the robotic arm 100 to move in the Z-axis direction as well.

[0031] Therefore, the fixed guide pin module 500 on the robotic arm 100 can also move in the X, Y, and Z directions. This is because, to achieve the desired pinning, movement in the four basic planes (left, right, up, and down) is required, as the transformer pinning consists of multiple horizontal pins and two symmetrical vertical sets. The principle of the entire mechanized automatic pinning process is as follows: the fixed guide pin module 500 has a large chamfer at its bottom. The robotic arm moves the fixed guide pin module 500 up and down in the Z-axis direction, pressing the large chamfer into the pins, thus achieving pinning.

[0032] Compared with traditional technology, this utility model adds an automated winding mechanism to the winding equipment, which greatly improves production efficiency compared with traditional manual winding.

[0033] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
