[0002] The demand for winding machines is increasing, and production efficiency and other factors are considered in the design of the equipment. The patent with application number 2020100274149 and title "Sleeve winding and rubber coating device" describes a machine frame as a load-bearing component. A sleeve feeding device is used to supply sleeves. An upper line device is used to supply copper wire. An upper and lower material feeding mechanism provides upper and lower raw materials for the winding component. A clamping device fixes the sleeve. A cutting device cuts the wrapped copper wire. A rubber belt mechanism provides a rubber-coated belt. The upper part of the machine frame is provided with a sleeve feeding device and an upper line mechanism. The vertical surface of the machine frame is provided with a wire guide, which realizes the transmission of copper wire and sleeve. The wire guide includes a fixed plate and a sleeve sleeve on the fixed plate, a copper wire tube, a sleeve notch on the sleeve sleeve, a sleeve feeding wheel at the sleeve notch, a wire tube notch on the copper wire tube, and a wire feeding wheel at the wire tube notch. The inside of the sleeve feeding wheel and the wire feeding wheel is provided with a motor structure, which drives the sleeve feeding wheel to rotate and moves the sleeve by extrusion between the sleeve feeding wheels. The motor structure drives the wire feeding wheel to rotate and moves the copper wire by extrusion between the wire feeding wheels. The wire guide is provided below the clamping device, which receives and fixes the sleeve to prevent position deviation during winding. The clamping device is connected to the machine frame through a first slide device on the machine frame. The first slide device allows the clamping device to move in the X-axis direction. The clamping device is provided with a sleeve clamp for fixing the sleeve. The clamping device is provided with a transmission device at one end, which drives the clamping device to move horizontally in the first slide device. The clamping device is also provided with a first winding device. The machine frame is also provided with a clamping part, which fixes the winding component and rotates to realize winding. The clamping part is also provided with a cutting device and a rubber belt mechanism, which are fixed by a moving frame. The moving frame includes a first moving frame and a second moving frame. The first moving frame is connected to the second sliding device on the machine frame. The first moving frame and the machine frame are displaced in the Z-axis direction by a motor device. The first moving frame is provided with a third sliding device, and the second moving frame moves in the Y-axis direction by a motor device in the vertical direction of the first moving frame. The cutting device is connected to the second moving frame by a support rod. The cutting device is also provided with a second winding device at one end. The rubber belt mechanism moves in the vertical plane of the second moving frame by the movement of the second moving frame. The machine frame is also provided with an upper and lower material feeding mechanism. The above scheme realizes high product efficiency with multiple shafts. During the process of multiple shafts, the transmission of multiple wires is unstable and cannot pass through the sleeve. Patent No. 202123031513.3. A utility model patent entitled "A Copper Wire Coating Mechanism" discloses a frame with a tape reel, a limiting part, a transmission mechanism, a cutting mechanism, and a transfer mechanism. The transmission mechanism includes a first transmission wheel and a first motor. The first transmission wheel rotates via the first motor and has a groove group. The cutting mechanism is movable relative to the frame. The transfer mechanism includes a rotating concave wheel, which rotates via a second motor and has a wire-rotating groove. This invention proposes a copper wire coating mechanism that enables tape winding of multi-strand copper wire. This design results in a small footprint, structural stability, and good transmission performance. Furthermore, this structure can be fixed to a winding machine and integrated with it. A patent application numbered 202122828898.X entitled "A Sleeve Winding Coating Device" discloses: "A single-axis sleeve winding machine, including a machine..." The machine frame is equipped with a tubing feeding device, a wire feeding device, a wire guide section, a tubing clamping device, a loading and unloading mechanism, a clamping part, and a wire cutting device. The wire guide section is located on the vertical surface of the machine frame and has a through-sleeve and a through-copper wire tube. The through-sleeve has a tubing notch, and a tubing feeding wheel assembly is located at the notch. The through-copper wire tube has a wire tube notch, and a wire feeding wheel assembly is located at the notch. A motor structure is located inside the through-sleeve and wire feeding wheel assemblies. The tubing clamping device can move laterally and has a tube cutting device. A first guide pin section is located on one side of the machine frame of the wire guide section, and a second guide pin section is located on the other side of the machine frame. This single-axis tubing winding machine achieves small-batch processing through a new connection structure, is easy to operate, simple to assemble and disassemble, and convenient for maintenance and debugging.

[0003] The aforementioned single-axis winding machine has low efficiency. Furthermore, if three-axis or more are made, the guide pin section is a single-arm mechanism, which makes the components too heavy and unstable. In addition, loading and unloading become new problems when designing a multi-axis machine. Utility Model Content

[0018] Example:

[0019] like Figures 1-3As shown, a biaxial winding machine loading and unloading pitch-changing mechanism includes a frame 1, on which a loading and unloading mechanism 2 is provided. The loading and unloading mechanism 2 includes a loading section 21 and an unloading section 22. The loading section 21 includes a first conveying device 211 and a first pitch-changing device 212. The first conveying device 211 is provided with a first positioning module 2111, and the first pitch-changing device 212 can contact or separate from the first positioning module 2111.

The second positioning module 2211 is provided on the device 221, and the second pitch-changing device 222 can contact or separate from the second positioning module 2211. In specific implementation, the clamping part 3 on the dual-axis winding machine includes a first clamping part 31 and a second clamping part 32. During the feeding process, the first clamping part 31 and the second clamping part 32 need to be fed simultaneously. Since there is a distance between the first clamping part 31 and the second clamping part 32, the two molds to be wound need to be separated during the feeding process. The molds to be wound are placed on the first transmission device 211 and then moved to the second transmission device 221. The first pitch-changing device 212 moves in one direction. During this process, the first pitch-changing device 212 approaches the first positioning module 2111. After the winding die moves to one position on the first positioning module 2211 and one on the first pitch-changing device 212, the first pitch-changing device 212 moves away from the first positioning module 2211. The first clamping part 31 and the second clamping part 32 are used to grip the winding die and perform winding by rotation. After the winding is completed, the die moves to the unloading part 22, and the second positioning module 2211 and the second pitch-changing device 222 move away from each other. The first clamping part 31 and the second clamping part 32 move away from each other. 2. After the completed winding mold is placed on the second positioning module 2211 and the second pitch changing device 222, the second pitch changing device 222 moves towards the second positioning module 2211. After getting close, the second transmission device 221 moves the completed winding mold to the right so that the completed winding mold is separated from the second pitch changing device 222 and the second positioning module 2211, thus completing a set of mold winding. The first transmission device 211 and the second transmission device 221 can be set to move the mold on them through a cyclic transfer mechanism, a traction mechanism, or a vibration method.

[0020] Based on the above embodiments, the pitch change method can be achieved by setting a telescopic clamp on the first transmission device, such as by using a clamp at a mold opening, with the second mold at the clamp location; the second transmission device has a placement opening set according to the distance between the first clamping part and the second clamping part, and the mold moves on the second transmission device after placement; this utility model provides another pitch change structure, specifically, the first pitch change device 212 includes a first pushing component 2121 and a first limiting part 2122 connected to the frame 1, the first pushing component 2121 is provided with a first pushing rod 21211, and the first pushing rod 21211 is fixedly connected to the first limiting part 2122; the second pitch change device 222 includes a second pushing component 2221 and a second limiting part 2222 connected to the frame 1, the second pushing component 2221 is provided with a second pushing rod 22211, and the second pushing rod 22211... 1 is fixedly connected to the second limiting part 2222; the first pushing component 2121 and the second pushing component 2221 control the movement of the first pushing rod 21211 and the second pushing rod 22211 to achieve control of pitch change. The specific pushing component can also be designed and implemented by a motor, cam, etc. From the perspective of implementation and cost, the first pushing component 2121 and the second pushing component 2221 are air pump structures; during the above movement, it may be affected by the gravity of the components, etc. In order to reduce the impact on the life of the protective components, the frame 1 is provided with a slide rail 12. The first limiting part 2122 and the second limiting part 2222 are respectively provided with a first sliding groove 21221 and a second sliding groove 22221 that match the slide rail 12; the first limiting part 2122 and the second limiting part 2222 slide on the slide rail 12 through the first sliding groove 21221 and the second sliding groove 22221.
