Specific embodiments

[0024] The embodiments of the technical solution of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and thus are only examples and cannot be used to limit the protection scope of the present utility model.

[0025] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present utility model belongs.

[0026] In the embodiment of the present utility model, the structure of the upper wire mechanism for a winding machine is as Figures 1 to 5 shown, which includes a mechanism frame 1, a linear drive module 2, a mounting frame 3, a swing drive module 4, a connecting member 5, and a wire feeding tube 6; the linear drive module 2 is fixed on the mechanism frame 1, and the linear drive module 2 is used to drive the mounting frame 3 to move linearly; the swing drive module 4 is installed on the mounting frame 3, and the swing drive module 4 is used to drive the connecting member 5 to perform a swing motion; the wire feeding tube 6 is installed on the connecting member 5, and the wire feeding tube 6 is used to guide the output copper wire; during the upper wire process, through the coordinated work of the linear drive module 2 and the swing drive module 4, the wire feeding tube 6 can achieve a combined motion of linear and swing, so as to control the position of the wire feeding tube 6 to better meet the requirements of the upper wire operation. The wire feeding tube 6 is preferably made of wear-resistant materials (such as ceramics, cemented carbide, etc.).

[0027] See Figure 1As shown, the linear drive module 2 includes a fixed seat 21 fixedly connected to the mechanism frame 1, a lead screw 22 rotatably mounted on the fixed seat 21, a drive motor 23 for driving the rotation of the lead screw 22, and a slider 24 threadedly engaged with the lead screw 22. When the drive motor 23 drives the lead screw 22 to rotate, the slider 24 is driven to move along the axial direction of the lead screw 22, and the mounting frame 3 is fixed on the slider 24. Through the threaded engagement structure of the lead screw 22 and the slider 24, efficient, stable, and precise linear motion control is achieved, and the displacement of the slider 24 is accurately adjusted to meet the positioning requirements.

[0028] Further, a position sensor (such as a photoelectric sensor, proximity switch) is installed on the fixed seat 21, which is not shown in the figure. When the slider 24 moves to the corresponding position, the position sensor is triggered. During installation and use, the position sensor is connected to the control system of the winding machine. When the equipment is running, when the linear drive module 2 drives the slider 24 to move to a predetermined position, the position sensor is triggered, and the control system receives the trigger signal to control the drive motor 23 to stop rotating, so as to control the slider 24 to stop moving, thereby accurately controlling the position of the wire feeding tube 6.

[0029] Combined Figures 2 to 4 , as a preferred implementation, the swing drive module 4 includes a support rod 41 mounted on the mounting frame 3 and rotatable about its own axis, an elbow arm 42 fixed to the upper end of the support rod 41, a single-acting cylinder 43 connected between the mounting frame 3 and the elbow arm 42, and a return spring 9 connected between the mounting frame 3 and the elbow arm 42. The single-acting cylinder 43 and the return spring 9 cooperate to drive the elbow arm 42 to drive the support rod 41 to rotate. The connecting member 5 is fixed to the lower end of the support rod 41. During the wire feeding process, when compressed air enters the single-acting cylinder 43, the single-acting cylinder 43 extends to drive the elbow arm 42 to swing, so as to drive the support rod 41 to rotate about its own axis, and further drive the wire feeding tube 6 to turn. During this process, the return spring 9 is stretched and stores energy. When it is necessary to control the wire feeding tube 6 to rotate and reset, the supply of compressed air to the single-acting cylinder is stopped, and the return spring 9 releases the stored energy and drives the single-acting cylinder 43 to shorten, further driving the elbow arm 42 and the support rod 41 to rotate, and further driving the wire feeding tube 6 to turn and reset. In this solution, the reset of the wire feeding tube 6 is not driven by the single-acting cylinder 43, but by pulling the return spring 9 to pull for reset, which avoids the hard drive when the wire feeding tube 6 returns, makes the reset process of the wire feeding tube 6 more compliant, and when the wire feeding tube 6 encounters slight jamming during the reset process, the return spring 9 can be moderately stretched and adaptively pass through the jam, playing a certain protective role for the wire feeding tube 6.

[0030] As another embodiment of the swing drive module 4: The swing drive module 4 includes a support rod 41 mounted on the mounting bracket 3 and rotatable about its own axis, an elbow arm 42 fixed to the upper end of the support rod 41, and a double-acting cylinder connected between the mounting bracket 3 and the elbow arm 42; The double-acting cylinder drives the support rod 41 to rotate by driving the elbow arm 42 to expand and contract; The connecting member 5 is fixed to the lower end of the support rod 41; In this embodiment, the rotation of the support rod 41 is controlled by controlling the extension and shortening of the double-acting cylinder, so that there is no need to provide the return spring 9 in the above embodiment.

[0031] In order to accommodate the installation of the return spring 9, a hanging member one 7 and a hanging member two 8 are respectively provided on the mounting bracket 3 and the elbow arm 42, and both ends of the return spring 9 are respectively connected to the hanging member one 7 and the hanging member two 8, so as to provide a return force for the elbow arm 42 through the return spring 9. Exemplarily, the hanging member one 7 and the hanging member two 8 are bolts, and are fixedly connected to the mounting bracket 3 / elbow arm 42 by screwing.

[0032] See Figures 1 to 4 , a hollow bearing seat 31 is fixed on the mounting bracket 3, the support rod 41 passes through the bearing seat 31, and a bearing 32 is installed between the support rod 41 and the bearing seat 31; Preferably, bearings 32 are provided at both the upper and lower ends inside the bearing seat 31. The setting of the bearings 32 can effectively support the support rod 41, and the bearings 32 reduce the friction between the support rod 41 and the bearing seat 31, ensuring the stability and smoothness of the support rod 41 during rotation.

[0033] Further, as Figure 5 shown, a connecting plate 33 is fixed on the mounting bracket 3, and a tension maintaining member 34 and a wire pressing member 35 are installed on the connecting plate 33; The tension maintaining member 34 is for the copper wire to pass through, so that the copper wire can maintain a good tension and avoid the copper wire from being slack, while the wire pressing member 35 can press the copper wire when the copper wire stops being conveyed. A wire passing guide hole 36 is provided on the connecting plate 33, and the wire pressing member 35 is arranged between the tension maintaining member 34 and the wire passing guide hole 36. The copper wire passes through the tension maintaining member 34 and the wire passing guide hole 36 in sequence. The wire passing guide hole 36 helps to guide the direction of the copper wire and ensures the accuracy and stability of its transmission path.

[0034] Specifically, the tension maintaining member 34 includes two wool felt pads 341 stacked and fixed on the connecting plate 33. The copper wire passes between the two wool felt pads 341. The gap between the wool felt pads can provide appropriate friction to ensure that the copper wire maintains a stable tension during transportation and avoid slack; Moreover, the wool felt pad 341 has the characteristics of being soft and wear-resistant, and can effectively protect the surface of the copper wire and avoid damage caused by friction.

[0035] Preferably, the wire pressing component 35 includes a wire pressing cylinder 351 fixed on the connecting plate 33 and a wire pressing plastic 352 installed at the driving end of the wire pressing cylinder 351. A baffle 331 opposite to the wire pressing plastic 352 is provided on the connecting plate 33. When conveying the copper wire, the copper wire passes through the gap between the wire pressing plastic 352 and the baffle 331. When stopping conveying the copper wire, the wire pressing cylinder 351 drives the wire pressing plastic 352 to press the copper wire against the baffle 331.

[0036] For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or variations derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
