Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically a three-hook needle type winding machine suitable for small annular magnetic rings. Background Technology

[0002] Magnetic property testing is an important means of characterizing materials under different testing environments, mainly including DC magnetic property testing, AC magnetic property testing, material remanence testing, material magnetic noise testing, and material shielding coefficient testing. Before conducting DC and AC magnetic property tests, copper wires of different specifications need to be wound around small ring-shaped samples. Currently, this process is mainly done manually, with operators manually winding two specifications of copper wires around the front and back of the sample. This method has many problems, such as being time-consuming and having a large degree of randomness in the quality of the wound coils, making it difficult to guarantee the consistency and reliability of the test results. Patent application number 202411302893.5 provides a ring winding machine for high-frequency transformer processing, based on the notched ring winding principle. This patent improves the stability of clamping the high-frequency transformer by setting a winding support frame on a moving slide rail. However, due to its structural design placing the winding wheel in the middle of the winding wheel, this layout limits the applicability of the equipment and cannot meet the winding requirements of small ring-shaped samples with an outer diameter of 40mm and an inner diameter of 32mm. On the other hand, invention patent application number 202411072705.4 provides an automated dual-magnetic winding machine based on the lever-hook type winding principle. This patent solves the defect of existing magnetic winding machines that cannot achieve automated winding of copper wire with dual magnetic rings. However, the first magnetic winding machine and the magnetic winding machine itself have complex structures and high costs, making them unsuitable for winding ring-shaped test samples in a laboratory environment. In summary, existing technologies still have shortcomings in handling the problem of rapid winding of small ring-shaped samples. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5As shown, a three-hook needle type winding machine suitable for small annular magnetic rings includes a mounting platform 31 and an aluminum beam 32 for enhancing the stability of the mounting platform 31. A wire feeding device 3 is provided on the lower surface of the mounting platform 31, including a coil shaft 33, a left coil 34, and a right coil 35. A thrust motor mounting bracket 23 is provided on the upper surface of the mounting platform 31, and the thrust motor mounting bracket 23 is connected to the mounting platform 31 via two mounting bracket connectors 24. A rotating mechanism 1 and a three-hook needle winding mechanism 2 are mounted on the thrust motor mounting bracket 23. The rotating mechanism 1 has a mechanism for clamping and driving the magnetic ring sample 10 to rotate. The rotating drive device 4 and the three-hook winding mechanism 2 include an upper hook 201, a right hook 211 and a left hook 221. The upper hook 201, right hook 211 and left hook 221 are driven by corresponding thrust motors. The three sets of hooks sequentially perform vertical hooking, horizontal hooking and inclined hooking actions. Utilizing the stability of the mounting platform 31 and the wire supply of the wire supply device, the cooperation of the thrust motor fixing frame 23 and the rotating mechanism 1 realizes the rotation of the magnetic ring sample. The three-hook winding mechanism realizes vertical, horizontal and inclined hooking actions through the cooperation of the three hooks, thereby solving the problem of rapid winding of small ring samples.

[0023] Furthermore, the drive device 4 includes a positioning clamping wheel 11, a positioning clamping spring 12, a driven gear 13, a positioning clamping wheel shaft 14, a driving gear 15, and a stepper motor 16. The positioning clamping wheel 11 clamps the magnetic ring sample 10 through the positioning clamping spring 12. The positioning clamping wheel 11 and the driven gear 13 are keyed together through the positioning clamping wheel shaft 14. The driven gear 13 and the driving gear 15 are driven by gear meshing. Power is transmitted to the positioning clamping wheel 11 through the positioning clamping wheel shaft 14. By using a threaded connection, the upper hook 201, the right hook 211, and the left hook 221 are respectively screwed to the thrust motor, and the thrust motor is fixed on the thrust motor mounting bracket 23. This simplifies the connection structure between the hooks and the thrust motor and reduces the complexity of installation and debugging.

[0024] Furthermore, the upper hook 201, the right hook 211, and the left hook 221 are respectively screwed to the corresponding thrust motors via threads, and the thrust motors are fixed on the thrust motor mounting bracket 23.

[0025] Furthermore, the coil shaft 33 is connected to the aluminum beam 32 through a shaft hole, and the left coil 34 and the right coil 35 are mounted on the coil shaft 33 to provide different types of metal wire for the three-hook winding mechanism 2.

[0026] Furthermore, the upper hook 201 moves downward to hook the metal wire and pull it to a vertical position; the right hook 211 moves to the left to receive the metal wire and pull it to a horizontal position; the left hook 221 moves to the upper left to receive the metal wire and pull it to an inclined position; the upper hook 201 moves downward again to complete the winding loop. During the winding process, the upper hook 201, right hook 211, and left hook 221 perform movements in different directions: the upper hook 201 moves downward to hook and pull the metal wire to a vertical position; the right hook 211 moves to the left to receive and pull the metal wire to a horizontal position; and the left hook 221 moves to the upper left to receive and pull the metal wire to an inclined position. Finally, the upper hook 201 moves downward again to complete the winding loop. In this way, the coordinated movement of the three hooks enables accurate traction and loop closure of the metal wire, thus solving the problem of accurate traction and loop closure of the metal wire during the winding process for small ring-shaped samples.

[0027] Furthermore, the magnetic ring sample 10 is suitable for small annular samples with an outer diameter ≤ 40 mm and an inner diameter ≥ 32 mm. This technical feature, by limiting the sample size, helps the winding machine to better control the stability of the sample and the uniformity of the winding during operation. Moreover, through this size limitation, the winding machine can better optimize its structure and function during the design and manufacturing process to accommodate samples of specific sizes, improving winding efficiency and quality.

[0028] Furthermore, the thrust motor is fixed to the thrust motor mounting bracket 23 by M3 cylindrical head screws.

[0029] Furthermore, aluminum beam 32 is made of aluminum profiles of specification 4545.

[0030] Working principle: During automatic winding, the upper hook push motor drives the upper hook 201 downward through the magnetic ring sample 10 and the mounting platform 31, hooking up the different types of metal wires provided by the left coil 34 and the right coil 35. The upper push motor 20 drives the upper hook 201 upward, passing the metal wire through the magnetic ring sample 10. At this time, the metal wire remains vertical under the traction of the upper hook 201. The right push motor 21 drives the right hook 211 to move to the left, hooking up the vertical metal wire. At the same time, the upper hook 201 releases the metal wire, and the right push motor 21 drives the right hook 211 to move to the right. The metal wire remains horizontal under the traction of the right hook 211; while the left thrust motor 22 drives the left hook 221 to move upward and to the left, hooking up the horizontal metal wire. At the same time, the right hook 211 releases the metal wire, and the left thrust motor 22 drives the left hook 221 to move downward and to the right. At this time, the metal wire remains inclined under the traction of the right hook 221; finally, the upper thrust motor 20 drives the upper hook 201 downward through the annular sample box 10 to hook up the inclined metal wire, and the left hook 211 releases the metal wire. The above mechanical structure realizes the automatic winding of the annular sample box 10.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
