[0002] In current industrial production, winding machines are key equipment for wire processing. Their performance and efficiency directly affect the operation of the entire production line. They are widely used in the winding of wires, cables, plastic wires and other wires, especially in the production of 3D printing wires. By configuring winding machines downstream of the device for extruding 3D printing wires, the winding of such wires can be completed while the 3D printing wires are being produced, thereby improving production efficiency. However, the existing traditional winding machines mainly manually pass the wire through multiple wire wheels in sequence, and then manually pull the wire and wind it on a rotating carrier, such as a rotating shaft, a winding reel, etc. This existing winding method not only has low manual operation efficiency, but also, especially when a large amount of wire needs to be processed, workers need to repeatedly perform actions such as threading and tying the wires, which is labor-intensive and prone to errors. Moreover, due to the uncontrollability of manual operation, the arrangement of the wires is often not neat, and the winding density is difficult to maintain consistency, which affects the quality and consistency of the product. Therefore, how to realize the automation of the winding process, improve production efficiency, and reduce manual labor intensity has become an urgent problem to be solved in the current development of winding machine technology.

[0034] See also Figures 2 to 4The wire feeding mechanism a1 also includes a driven wheel group a16 arranged between the wire wheel group a11 and the driving wheel group a12.

Before winding, the wire needs to be manually inserted into the wire feeding mechanism a1, but since it cannot be ensured that the length of the wire passing through the conductor channel a13 is constant each time, the cutting mechanism a6 is set to cut the wire to realize the "zeroing" function, and then the meter encoder a163 obtains the length of the wire movement, and the length of the wire winding can be obtained.

By providing the upper positioning wheel a71 and the lower positioning wheel a72, the part of the wire that passes through the wire channel a13 can be prevented from jumping up and down and scratching the wire channel a13 and the wire. At the same time, the staggered arrangement of the upper positioning wheel a71 and the lower positioning wheel a72 can avoid the upper positioning wheel a71 and the lower positioning wheel a72 from interfering with each other, and can ensure that the wires can all pass into the wire groove a73, further preventing the wires from jumping up and down.

When the clamping member b122 contacts the positioning disk b121, they are electrically connected and send out a detection signal. Through the above-mentioned setting, it can be determined whether the wire is clamped, because when the wire is clamped between the positioning disk b121 and the clamping member b122, the two will not contact, and therefore no detection signal will be generated, thereby determining that the wire has been clamped, and when the wire is not clamped, the two will contact to generate a detection signal, thereby determining that the wire is not clamped.

[0046] See also Figure 8 , Fig.12 and Fig.13 The outer periphery of the positioning sleeve b31 is also constructed with a radially extending positioning convex edge b32, and the positioning convex edge b32 is used to fit tightly against the surface of the baffle c2 when the conical surface b311 is inserted into the cylinder c1, thereby fitting the winding drum c and making the winding drum c rotate more smoothly.

[0047] This embodiment also provides a winding method using the above winding machine, comprising the following steps: The wire is passed through the wire wheel assembly a11, the driving wheel assembly a12 and the wire channel a13 in sequence; the robot d grabs the winding drum c and sets the winding drum c on the rotating shaft b11. When grabbing the winding drum c, the robot d identifies the position of the hollow part c11 of the winding drum c, for example, by using the visual recognition method in the prior art to get the coordinates of the hollow part c11, and then calculates the angle that the feeding gripper d1 needs to rotate by a computer algorithm, so that the hollow part c11 of the winding drum c installed with the rotating shaft b11 is aligned with the clamping assembly b12; Drive the wire feeding mechanism a1 to move to a preset position along the X-axis in a direction close to the winding device b, so that the wire channel a13 is close to the winding device b; The driving wheel set a12 drives the wire to move, so that the end of the wire passes through the wire channel a13; The cutting mechanism a6 cuts off the portion of the wire extending out of the conductor channel a13. Since it cannot be ensured in the previous step that the length of the wire passing through the conductor channel a13 is consistent each time, the cutting mechanism a6 cuts off the wire to achieve "zero adjustment". The length of the subsequent wire travel is calculated from the cut portion by the meter encoder a163 to confirm the winding length. The driving wheel assembly a12 drives the wire to move a preset distance in the direction of the winding device b, so that the end of the wire passes through the hollow portion c11 and enters between the connecting member b121.2 and the clamping portion b126, and is clamped by the clamping assembly b12; The rotating shaft b11 rotates to realize the winding of the wire. Every time the rotating shaft b11 rotates one circle, the wire feeding mechanism a1 moves away from the rotating shaft b11 by a preset distance along the X-axis direction. At the same time, the wire feeding mechanism a1 reciprocates along the Y-axis to realize the wire arrangement, and moves upward along the Z-axis according to the thickness of the wire wound on the winding drum c. The length of the wire winding is obtained through the meter encoder a163. When the preset value is reached, the rotating shaft b11 stops rotating and the cutting mechanism a6 cuts the wire; the robot d clamps the end of the wire through the wire gripper d2 and snaps it into the bayonet c21, thereby completing the wire winding of a winding reel c; or, the glue component b5 controls the swing arm b52 to approach the end of the wire, and the rotating shaft b11 continues to rotate, thereby pressing the tape against the end of the wire to achieve the finishing touch.

[0048] As an improved solution, the minimum spacing between the end of the wire channel a13 and the axis of the rotating shaft b11 in the X-axis direction is 8-12 mm, preferably 10 mm. Through the above arrangement, the wire channel a13 can be extended to be as close to the winding reel c as possible, thereby preventing the wire from extending out of the wire channel a13 too long and causing jumping.

[0049] Compared with the prior art, the present invention provides a feeding device a, which is used to feed the wire to the winding device b before winding and clamped by the clamping assembly b12, thereby realizing automatic wire feeding and loading. In the winding process, the wire feeding mechanism a1 moves a preset distance away from the rotating axis b11 every time the rotating axis b11 rotates one circle, thereby preventing the wound wire from colliding with the conductor channel a13. The present invention has a high degree of automation, can effectively improve work efficiency, and reduce manual fatigue.
