[0018] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0019] As shown in the figure, a fully automatic three-axis wire feeding device includes an X-axis high-precision linear module 2, a Y-axis high-precision linear module 3, a Z-axis high-precision linear module 4, an anti-jump wire component 9, an enameled wire impurity removal component 12 and a double-station wire feeding nozzle fine-tuning component 13 located on a base 1. The combined action of the X-axis high-precision linear module 2, the Y-axis high-precision linear module 3 and the Z-axis high-precision linear module 4 can realize the position adjustment of the anti-jump wire component 9, the enameled wire impurity removal component 12 and the double-station wire feeding nozzle fine-tuning component 13 in six directions of X, Y and Z axes, thereby realizing real-time adjustment of the position of the wire feeding nozzle 134 in the double-station wire feeding nozzle fine-tuning component 13 in six directions during the winding process.

[0020] The X-axis high-precision linear module 2 and the Y-axis high-precision linear module 3 are both arranged horizontally and perpendicular to each other. The Y-axis high-precision linear module 3 is connected to the X-axis slide of the X-axis high-precision linear module 2 via a horizontally arranged module transition base 5. The X-axis slide is capable of reciprocating along the lead screw in the X-axis high-precision linear module 2 with the module transition base 5 under the action of the servo motor in the X-axis high-precision linear module 2, thereby adjusting the position of the wire feed nozzle 134 in the X-axis direction. The machine base is equipped with a linear guide 6 arranged parallel to the X-axis high-precision linear module 2. The module transition base 5 is equipped with a slide groove compatible with the structure of the linear guide 6. The combination of the linear guide 6 and the slide groove improves the stability of the module transition base 5 during movement. The frame of the X-axis high-precision linear module 2 is equipped with a first photoelectric sensor, and the module transition base 5 is equipped with a first light shielding plate corresponding to the second photoelectric sensor 10. The combination of the first photoelectric sensor and the first light shielding plate facilitates the determination of the starting position of the wire feed nozzle 134 during movement in the X-axis direction.

[0021] The Z-axis high-precision linear module 4 is vertically mounted and connected to the Y-axis slide of the Y-axis high-precision linear module 3 via a vertically mounted mounting plate 7. The Y-axis slide, driven by the servo motor in the Y-axis high-precision linear module 3, can move back and forth along the lead screw in the Y-axis high-precision linear module 3 with the mounting plate 7, thereby adjusting the position of the wire feed nozzle 134 in the Y-axis direction. A second photoelectric sensor 10 is provided on the frame of the Y-axis high-precision linear module 3, and a second light shielding plate 11 is provided on the mounting plate 7, corresponding to the second photoelectric sensor 10. The coordinated use of the second photoelectric sensor 10 and the second light shielding plate 11 facilitates determination of the starting position of the wire feed nozzle 134 as it moves in the Y-axis direction.

[0022] The anti-jump wire assembly 9, the enameled wire impurity removal assembly 12, and the double-station wire feeding nozzle fine-tuning assembly 13 are sequentially arranged on the Z-axis slide of the Z-axis high-precision linear module 4 from top to bottom. The anti-jump wire assembly 9, the enameled wire impurity removal assembly 12, and the double-station wire feeding nozzle fine-tuning assembly 13 are all connected to the Z-axis slide via the mounting base 8. The Z-axis slide can move back and forth along the lead screw in the Z-axis high-precision linear module 4 with the mounting base 8 under the action of the servo motor in the Z-axis high-precision linear module 4, thereby realizing the position adjustment function of the wire feeding nozzle 134 in the Z-axis direction. A third photoelectric sensor is provided on the frame of the Z-axis high-precision linear module 4, and a third light shielding plate is provided on the mounting base 8 corresponding to the third photoelectric sensor. The coordinated use of the third photoelectric sensor and the third light shielding plate can conveniently determine the starting position of the wire feeding nozzle 134 when it moves in the Z-axis direction.

[0023] The anti-jump wire assembly 9 includes a tension spring 901, an anti-jump wire combination wheel fixed long strip 902 and an anti-jump wire combination wheel 903. Two tension springs 901 are provided and are vertically symmetrically arranged on both sides of the mounting base 8. The top ends of the two tension springs 901 are connected to the fixed plate on the top of the mounting base 8 through the upper tension spring support 904, and the bottom ends of the two tension springs 901 are respectively connected to the two lower tension spring supports 905 on the anti-jump wire combination wheel fixed long strip 902. The tension spring 901 can slowly lower the anti-jump wire combination wheel fixed long strip 902 when the full-automatic three-axis wire feeding device suddenly loses power, thereby slowly lowering the anti-jump wire assembly 9, the enameled wire impurity removal assembly 12 and the double-station wire feeding nozzle fine-tuning assembly 13 on the mounting base 8, ultimately avoiding damage to the wire feeding nozzle 134 in the double-station wire feeding nozzle fine-tuning assembly 13, thereby protecting the wire feeding nozzle 134. Anti-jumping wheel assembly 903 is installed at both ends of the long fixed strip 902. Anti-jumping wheel assembly 903 is used to prevent wire jumps during winding. The middle porcelain wheel on the anti-jumping wheel assembly 903 is connected to the high-speed bearing. The middle porcelain wheel is made of ultra-fine polishing and works in conjunction with the high-speed bearing to minimize wire jumps during winding, maintaining the original stability of the winding tension.

[0024] The enameled wire impurity removal component 12 includes an enameled wire impurity removal fixing bar 121, and impurity removal fixing wheels 122 are provided at both ends of the enameled wire impurity removal fixing bar 121. A wool felt 123 is provided in the middle groove of the impurity removal fixing wheel 122. The wool felt 123 can remove the surface quality of the enameled wire, further ensuring the original stability of the winding tension and the quality of the winding wire.

[0025] The double-station wire feed nozzle fine-tuning assembly 13 includes a mounting base 132, a precision fine-tuning slide 132, a wire feed nozzle mounting member 133, and a wire feed nozzle 134. The mounting base 132 is an inverted, nearly Y-shaped plate. The nearly Y-shaped structural design enables the double-station installation of the wire feed nozzle 134. The top of the mounting base 132 is connected to the mounting base 8, and the two bottom ends of the mounting base 132 are respectively connected to a precision fine-tuning slide 132. The precision fine-tuning slide 132 is a cross-guide type XY translation stage equipped with an opposing clamping device 135. The cross-guide type XY translation stage can achieve high-precision and smooth movement, wherein the opposing clamping device 135 can prevent the wire feed nozzle 134 from deviating during the movement of the precision fine-tuning slide 132. The working plane of the precision fine-tuning slide 132 is set vertically and connected parallel to the wire feed nozzle mounting member 133. The bottom end of the wire feed nozzle mounting member 133 is provided with a wire feed nozzle 134. The precision fine-tuning slide 132 can achieve precise displacement adjustment in four directions of the Z axis and X axis with the wire feed nozzle mounting member 133 and the wire feed nozzle 134. The wire feed nozzle 134 has a four-section variable diameter design, and the outer diameter of each section of the wire feed nozzle 134 is smaller than the outer diameter of the wire feed nozzle 134 of the previous section. The four-section variable diameter design of the wire feed nozzle 134 prevents the enameled wire from being broken by the force during the winding process, and simultaneously reduces the head area of ​​the wire feed nozzle 134, thereby enabling winding in a narrower position. In addition, the wire feed nozzle 134 is precision-machined from a high-hardness super-hard alloy material. The ends and inner hole are all precision-machined to ensure that the enameled wire is not scratched during the wire feeding process. It has extremely high rigidity and hardness, is not easy to bend or clog, and is impact-resistant and wear-resistant.

[0026] When in use, first use the precision fine-tuning slide 132 to precisely adjust the initial position of the wire feeding nozzle 134, and then use the X-axis high-precision linear module 2, the Y-axis high-precision linear module 3 and the Z-axis high-precision linear module 4 to realize the real-time adjustment of the position of the wire feeding nozzle 134 in the six directions of X, Y and Z axes during the winding process. When the X-axis high-precision linear module 2 drives the wire feeding nozzle 134 to adjust its position in the X-axis direction, the first photoelectric sensor is used to determine the starting position to ensure the movement accuracy. When the Y-axis high-precision linear module 3 drives the wire feeding nozzle 134 to adjust its position in the Y-axis direction, the second photoelectric sensor 10 is used to determine the starting position to ensure Moving accuracy, the Z-axis high-precision linear module 4 drives the wire feeding nozzle 134 to adjust its position in the Z-axis direction, and uses the third photoelectric sensor to determine the starting position to ensure moving accuracy. During the wire feeding process, the enameled wire will improve the stability of the wire tension under the action of the middle porcelain wheel of the anti-jump wire component 9 to prevent the occurrence of enameled wire jumping; under the action of the wool felt 123 of the enameled wire impurity removal component 12, impurities on the surface of the enameled wire are removed to ensure the quality of the wound wire, and further ensure the original stability of the winding tension; the double-station design of the double-station wire feeding nozzle fine-tuning component 13 enables a fully automatic three-axis wire feeding device to simultaneously perform two enameled wire feeding actions, thereby improving production efficiency.

[0027] Therefore, the present invention adopts the fully automatic three-axis wire feeding device of the above structure to effectively improve the stability of wire tension, prevent the occurrence of enameled wire jumper phenomenon, and improve production efficiency.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
