Description
Technical Field
[0001] The utility model relates to the technical field of watch movement, in particular to a novel watch movement coil. Background Art
[0002] As people pay more and more attention to health and lifestyle, wearable devices have become an important market. Among them, smart watches are one of the most popular wearable devices. Smart watches can not only display time, but also provide a variety of functions, such as notification reminders, health monitoring, exercise tracking, voice assistants, payments, etc.
[0003] In the production of existing smart watches, the ends of the enameled wire are scattered and there is no place to wrap the wire. As a result, when the coil and PCB are subsequently welded together, the wire needs to be pulled manually. The enameled wire can only be welded after passing over the soldering point. Moreover, the enameled wire is very thin and difficult to operate. Utility Model Content
[0004] In view of the above background technology, the prior art has the following shortcomings and defects: when the coil and the PCB are welded together, the wire needs to be pulled manually, the enameled wire needs to pass over the welding point before welding, and the enameled wire is very thin and difficult to operate.
[0005] The utility model discloses a novel watch movement coil, comprising a main plate, a metal pressing plate installed above the main plate, a PCB board and a stator plate arranged between the main plate and the metal pressing plate, a wire rack and a rotor assembly installed on the stator plate, an enameled wire arranged on the wire rack, a coil bracket installed at one end of the wire rack close to the PCB board, a metal winding post installed on the coil bracket, and the metal winding post arranged on a side close to the PCB board.
[0006] Furthermore, the metal wire winding pole and the bracket are integrally formed by injection molding in a mold, and one end of the metal wire winding pole is flattened.
[0007] Furthermore, a welding point is arranged at one end of the PCB board, and the metal winding column is arranged above the welding point.
[0008] Furthermore, a stopper is fixedly mounted on the coil support, and the stopper is arranged between the metal winding column and the enameled wire.
[0009] Furthermore, a positioning column is fixedly mounted on the coil support, and a positioning hole corresponding to the positioning column is provided on the wire rack.
[0010] Furthermore, the lower end surface of the coil support is in contact with the upper end surface of the wire rack, and many small round holes are arranged on the metal pressing sheet.
[0011] Furthermore, a coil pressing block is provided at one end of the wire rack away from the metal winding column, and the coil pressing block is arranged above the wire rack and mounted on the main splint.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The utility model is provided with a wire rack, a metal winding column, a coil support, an enameled wire and other components. During the working process, one end of the metal winding column is flattened to prevent the wire from loosening during winding. The metal winding column, the wire rack and the coil support cooperate with each other, so that the enameled wire is already wound on the metal winding column during winding. There is no need to manually pull the wire head during subsequent welding, which solves the problem that the enameled wire is very thin and difficult to operate.
[0014] 2. The utility model is provided with positioning columns, positioning holes and other components. The coil bracket and the wire rack are fixedly connected through the positioning column components and the positioning holes, and the small round holes on the metal pressing plate are matched with the round columns of the main splint, and are fixed by hot-press riveting in the later stage. Since the metal wire winding column will not melt during the welding process, the problem that the plastic wire winding column will melt together with the enameled wire when welding the wire is solved, and there is a certain probability that the soldering points on the PCB board will be covered, resulting in the problem of false soldering or inability to solder the enameled wire and the PCB soldering points.

By arranging the coil bracket 8, it is avoided that the wire ends of the enameled wire 7 are scattered, and the starting end and the ending end of the enameled wire 7 are respectively wound on the two metal winding columns 9 of the coil bracket 8, so as to avoid the need for manual pulling of the wire ends when the enameled wire 7 and the PCB are welded together later, thereby improving work efficiency.
[0026] Furthermore, the metal wire winding post 9 and the bracket are integrally formed by injection molding in a mold, and one end of the metal wire winding post 9 is flattened to prevent it from loosening when winding the wire. A welding point is provided at one end of the PCB board 3, and the metal wire winding post 9 is provided above the welding point. The metal wire winding post 9 will not melt during the welding process, and has higher stability.
[0027] Furthermore, a stopper 10 is fixedly mounted on the coil support 8, and the stopper 10 is arranged between the metal winding column 9 and the enameled wire 7. The stopper 10 on the coil support 8 blocks the enameled wire 7 to prevent the enameled wire 7 from loosening during the winding process.
[0028] Furthermore, a positioning column 11 is fixedly installed on the coil bracket 8, and a positioning hole 12 corresponding to the positioning column 11 is provided on the wire frame 5. The lower end surface of the coil bracket 8 is fitted with the upper end surface of the wire frame 5, and many small round holes are provided on the metal pressing sheet 2, which is fixed by hot pressing riveting later.
[0029] Furthermore, a coil pressing block 13 is provided at one end of the bobbin 5 away from the metal winding pole 9. The coil pressing block 13 is arranged above the bobbin 5 and installed on the main splint 1. One end of the bobbin 5 is fixed by the coil pressing block 13, thereby maintaining the stability of the bobbin 5.
[0030] When using the utility model: by setting the coil bracket 8, the wire ends of the enameled wire 7 are prevented from being scattered, and the starting end and the ending end of the enameled wire 7 are respectively wound on the two metal winding posts 9 of the coil bracket 8, so that when the enameled wire 7 and the PCB board 3 are subsequently welded together, there is no need to manually pull the wire ends. At the same time, since the metal winding posts 9 will not melt during the welding process, the welding is reliable and more stable, and the block 10 on the coil bracket 8 blocks the enameled wire 7 to prevent the enameled wire 7 from loosening during the winding process.
