Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Reference Figures 2 to 3 The present application provides an embodiment: an automatic inductance winding point machine, comprising a lower casing 1 made of high-quality steel material, which has good compression resistance and stability, laying a solid foundation for stable operation of the entire device, effectively resisting external interference and internal mechanical operation vibration, and ensuring accurate relative position of each component under complex working conditions. The top end of the lower casing 1 is fixedly connected with a bottom plate 4 made of lightweight aluminum alloy material, which significantly reduces the overall weight of the device while ensuring sufficient strength to support the numerous components above, facilitating the transportation and installation layout adjustment of the device, and the aluminum alloy material has excellent corrosion resistance and can adapt to various production environments. The top end of the bottom plate 4 is rotatably connected with a rotating disc 18, which can flexibly and accurately rotate on the bottom plate 4, realizing efficient switching of related components between different stations, greatly improving the automation degree and continuity of the production process;

[0033] The top end of the rotating disc 18 is slidingly connected with a conveying plate 15, which can provide a basis for the operation of the subsequent assembly. The inside of the conveying plate 15 is slidingly connected with a coil 16.

The top end of the bottom plate 4 is fixedly connected with a cylinder two 19, which can accurately control the lifting height of the jacking plate 17, and ensure the consistency and reliability of each jacking action. The top end of the bottom plate 4 is fixedly connected with a guide rail one 21, which is made of high-precision chromium-molybdenum alloy steel linear guide rail. Chromium-molybdenum alloy steel has very high hardness and wear resistance. The unique design of the linear guide rail endows it with excellent guiding precision, enabling the relevant components to slide smoothly and accurately inside it, providing a stable and accurate positioning basis for the subsequent welding process, effectively reducing the welding deviation. The inside of the guide rail one 21 is slidingly connected with a solder pad 20, which can be welded together with the coil 16;

[0034] The top end of the bottom plate 4 is fixedly connected with a bracket one 22, which is made of stainless steel welding. The corrosion resistance of stainless steel material ensures that the bracket one 22 will not rust and corrode due to environmental factors during long-term use, thereby maintaining a stable structure at all times, providing a solid and reliable installation support for related components. The top and bottom ends of the bracket one 22 are fixedly connected with a cylinder three 23, which can quickly, smoothly and accurately drive the relevant components to move up and down, effectively improving the operation efficiency of the equipment and the accuracy of the welding operation.

Through ingenious mechanical structure design, it can generate enough clamping force by its own elasticity, firmly fix the related components, and ensure the stable and reliable position of the starting end of winding. The top end of the bottom plate 4 is fixedly connected with the support column 10, which can ensure that each part always maintains accurate relative position during work and maintains the stability of the overall structure. The protection assembly includes the upper casing 2, which is generally made of aluminum alloy material by pressure casting process. This material is light and has high strength, which can effectively block dust, debris and other external objects from entering the device and affecting the normal operation of each component, and will not add too much weight to the entire device. The inside of the upper casing 2 is fixedly connected with the observation window 3, which is made of tempered glass with high transparency and wear resistance. Its clear visibility facilitates the operator to observe the working state of the device inside at any time.

The slide in the support one 22 is processed with high precision, and the surface has high flatness and is coated with appropriate amount of lubricating grease, which has good cooperation precision with the sliding frame one 24. The inside of the guide rail one 21 is provided with a sliding groove, which can make the matched components slide smoothly and accurately in it;

[0040] The inside of the guide rail two 33 is provided with a sliding groove, which can ensure that the parts will not deviate left and right or jam during sliding, and ensure that the whole cutting and related processes are carried out in an orderly manner according to the established process. The bottom end of the punch holder 32 is provided with a punch, which is made of hard alloy material with high hardness and good toughness, and is treated by professional forging and quenching process. During the cutting operation, the punch can easily and neatly cut off the solder pad 20, making the cutting edge smooth and neat, and ensuring the high quality of the cutting work. The outside of the coil 16 is fixedly connected to the inside of the solder pad 20, and the two are tightly combined together by welding. During the subsequent transportation and operation process, the relative stability can be maintained at all times, and the loosening and separation can not easily occur, ensuring the integrity of the whole product and the smooth progress of the subsequent process. The inside of the guide wheel 29 is slidingly connected to the outside of the solder pad 20, and the guide wheel 29 can tightly fit the outer contour of the solder pad 20 to play a good guiding role, guiding the solder pad 20 to move smoothly along the accurate route, and ensuring the smooth connection between the processes of the device. The outside of the winding column 11 is slidingly connected to the inside of the other coil 16, and the size cooperation between the winding column 11 and the coil 16 is just right. When the winding column 11 rotates and winds, the wire 6 can be neatly wound on the winding column 11 to form the coil 16. The inside of the wire clamp 9 is in contact with the outside of the wire 6, and the part of the wire clamp 9 in contact with the wire 6 can uniformly apply clamping force to fix the wire 6.
