Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically to a variable pitch double needle winding mechanism. Background Technology

[0002] A winding machine is a device that winds a wire-like object onto a specific workpiece. It is usually used for winding copper wire. Most electrical products need to be wound with enameled copper wire to make inductor coils, and a winding machine can be used to complete this one or more processing steps.

[0003] Conventional double-needle winding machines work with multi-pin products and cannot adjust the needle pitch and winding process for different products, resulting in a limited range of applications for the winding mechanism. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a variable-pitch double-needle winding mechanism, aiming to solve the problem mentioned in the background art where the inability to adjust the distance between the wire nozzles results in a limited range of applications.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a variable-pitch double-needle winding mechanism, comprising two upright plates, with a support plate between the two upright plates. A first thread nozzle mounting plate is mounted on the top of the support plate via a Y-axis sliding member. A plurality of evenly distributed first thread nozzle mounting seats are mounted on the bottom of the first thread nozzle mounting plate, each first thread nozzle being mounted on a first thread nozzle mounting seat. Cylinders for driving the first thread nozzle mounting plate to move along the Y-axis direction of the support plate are mounted on both sides of the support plate. A second thread nozzle mounting plate is mounted on the bottom of the support plate via an X-axis sliding member. A second thread nozzle mounting seat corresponding to the first thread nozzle mounting seat is mounted on one side of the second thread nozzle mounting plate, and a second thread nozzle is mounted on the second thread nozzle mounting seat. A drive mechanism for driving the second thread nozzle mounting plate to move along the X-axis direction of the support plate is provided on one side of the support plate.

[0006] Furthermore, a limiting block is installed at the bottom of the support plate, and a limiting hole is opened on the limiting block. A guide rod that matches the limiting hole is installed at one end of the second wire nozzle mounting plate, and a spring is fitted on the guide rod.

[0007] Furthermore, the drive mechanism includes a servo motor, the output end of which is equipped with a camshaft, and a connecting rod is mounted on the camshaft. The end of the connecting rod away from the camshaft is connected to the second nozzle mounting plate.

[0008] Furthermore, the X-axis slider includes an X-axis slider and an X-axis slide rail, and the Y-axis slider includes a Y-axis slider and a Y-axis slide rail.

[0009] Furthermore, a second cylinder is installed on one side of each of the upright plates, and the output end of each second cylinder is connected to a crankshaft. The support plate is disposed between the two crankshafts.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a compact structure and strong practicality. By using a servo motor to drive the cam and connecting rod, the second thread nozzle on the second thread nozzle mounting plate is controlled to move left and right, thereby changing the left and right distance between the first and second thread nozzles. By using a first cylinder to drive the first thread nozzle on the first thread nozzle mounting plate to move back and forth, the front and back distance between the first and second thread nozzles is changed, thus realizing the adjustment of the front and back and left and right distances of the first and second thread nozzles. Therefore, it can be applied to the wrapping process of various products with different needle pitches and the wrapping process of alternating thread nozzles. Through the combined use of springs and guide rods, the transmission gap between the planetary gears in the right angle reducer can be eliminated, realizing the precision of the left and right adjustment of the first and second thread nozzles.

[0017] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-5As shown, this utility model provides a variable-pitch double-needle winding mechanism, including two upright plates 1, with a support plate 2 between the two upright plates 1. A first thread nozzle mounting plate 4 is mounted on the top of the support plate 2 via a Y-axis sliding member 3. The Y-axis sliding member 3 includes a Y-axis slider and a Y-axis slide rail. The Y-axis slider is fixed to the top of the support plate 2, and the Y-axis slide rail is fixed to the bottom of the first thread nozzle mounting plate 4. Under the action of the Y-axis slider and the Y-axis slide rail, the first thread nozzle mounting plate 4 is slid along the support plate 3 in the Y-axis direction. Multiple evenly distributed first thread nozzle mounting seats 5 are mounted on the bottom of the first thread nozzle mounting plate 4 via bolts. A first thread nozzle 6 is mounted on each of the first thread nozzle mounting seats 5. First cylinders 7 are mounted on both sides of the support plate 2 to drive the first thread nozzle mounting plate 4 to move along the Y-axis direction of the support plate 2. The first cylinders 7 control the movement of the first thread nozzle mounting plate 4. The support plate 2 provides power for moving in the Y direction. A second wire nozzle mounting plate 9 is mounted on the bottom of the support plate 2 via an X-axis sliding member 8. The X-axis sliding member 8 includes an X-axis slider and an X-axis slide rail. The X-axis slider is mounted on the top of the second wire nozzle mounting plate 9 via bolts, and the X-axis slide rail is mounted on the bottom of the support plate 2 via bolts. Under the action of the X-axis slider and the X-axis slide rail, the second wire nozzle mounting plate 9 can drive the second wire nozzle 11 to move left and right along the X-axis direction of the support plate 2. A second wire nozzle mounting seat 10 corresponding to the first wire nozzle mounting seat 5 is mounted on one side of the second wire nozzle mounting plate 9. The second wire nozzle 11 is located behind the first wire nozzle 6. The second wire nozzle 11 is mounted on the second wire nozzle mounting seat 10. A drive mechanism 12 for driving the second wire nozzle mounting plate 9 to move along the X-axis direction of the support plate is provided on one side of the support plate 2.

[0019] like Figure 1-5 As shown, the first cylinder 7 drives the first thread nozzle mounting plate 4 to move along the Y-axis of the support plate 2, indirectly causing the first thread nozzle 6 to move back and forth, thereby changing the front-to-back distance between the corresponding first thread nozzle 6 and the second thread nozzle 11; the drive mechanism 12 drives the second thread nozzle mounting plate 9 to move along the X-axis of the support plate 2, indirectly causing the second thread nozzle 11 to move left and right, thereby changing the left and right distance between the corresponding first thread nozzle 6 and the second thread nozzle 11, thus adjusting the front-to-back and left and right distances between the corresponding first thread nozzle 6 and the second thread nozzle 11 accordingly, so as to be applicable to the wrapping process of various products with different needle pitches, and can also complete the alternating wrapping process of thread nozzles.

[0020] The drive mechanism 12 includes a servo motor 16 and a right-angle reducer. A camshaft 17 is installed at the output end of the right-angle reducer. A connecting rod 18 is rotatably installed on the camshaft 17. The end of the connecting rod 18 away from the camshaft 17 is rotatably connected to one end of the second wire nozzle mounting plate 9.

[0021] like Figure 3As shown, the output end of the servo motor 16 is connected to the input end of the right-angle reducer. The camshaft 17 rotates under the drive of the right-angle reducer, and under the action of the connecting rod 18, it drives the second wire nozzle mounting plate 9 to move left and right.

[0022] The bottom of the support plate 2 is equipped with a limiting block 13, and the limiting block 13 has a limiting hole. One end of the second wire nozzle mounting plate 9 is equipped with a guide rod 14 that matches the limiting hole, and a spring 15 is fitted on the guide rod 14.

[0023] like Figure 3 As shown, the spring 15 is located between the limiting block 13 and the second wire nozzle mounting plate 9. Under the action of the spring 15 and the guide rod 14, it is used to eliminate the transmission backlash of the planetary gear in the right angle reducer and improve the accuracy of the left and right movement of the second wire nozzle 11.

[0024] Each side of the upright plate 1 is equipped with a second cylinder 19 by bolts. The output end of each second cylinder 19 is rotatably connected to a crankshaft 20. The support plate 2 is fixedly installed between the two crankshafts 20.

[0025] like Figure 1 As shown, by activating the second cylinder 19, the output end of the second cylinder 19 drives the support plate 2 to rotate up and down through the crankshaft 20, thereby synchronously adjusting the height of the first nozzle 6 and the second nozzle 11, and realizing the overall movement of the first nozzle 6 and the second nozzle 11 in all directions.

[0026] Operating principle: Activating the first cylinder 7 pushes the first wire nozzle on the first nozzle mounting plate 4 to move along the Y-axis of the support plate 2, causing the first wire nozzle 6 to move back and forth relative to the second wire nozzle 11, thereby adjusting the front-to-back distance between the first wire nozzle 6 and the second wire nozzle 11. Activating the servo motor 16 drives the camshaft 17 to rotate. During the rotation of the camshaft 17, the second wire nozzle 11 on the second nozzle mounting plate 9 moves along the X-axis of the support plate 2 via the connecting rod 18, thereby adjusting the left-to-right distance between the second wire nozzle 11 and the first wire nozzle 6. This achieves the adjustment of the front-to-back and left-to-right distance between the first wire nozzle 6 and the second wire nozzle 11. Activating the second cylinder 19 drives the support plate 2 to rotate up and down via the crankshaft 20, thereby synchronously adjusting the height of the first wire nozzle 6 and the second wire nozzle 11. Overall, this achieves the front-to-back, left-to-right, and up-to-down movement of the first wire nozzle 6 and the second wire nozzle 11.

[0027] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
