[0002] As China's stepper motor industry continues to grow and develop, the industry scale continues to expand, and the technical level continues to improve. Therefore, many companies regard the stepper motor industry as a key focus for future development, hoping to promote the development of China's stepper motor industry by continuously investing in new technologies and technological improvements.

[0003] A stepper motor, also known as a pulse motor, is an electric motor that converts electrical pulse signals into corresponding angular or linear displacement. Based on the fundamental principle of electromagnetism, stepper motors precisely control the motor's rotation angle and speed by controlling the frequency and number of pulse signals. With each input pulse signal, the stepper motor's rotor precisely rotates a fixed angle (step angle) or moves forward a fixed distance. The output displacement (angular or linear) is proportional to the number of input pulses, and the speed is proportional to the pulse frequency.

[0004] During the production process of existing stepper motors, a large number of people are required to solder multiple terminal wires onto the circuit board for assembly. This involves many production steps, high labor costs, low production efficiency, and is prone to errors, resulting in the stepper motors being repaired and scrapped, a serious waste of raw materials, and an invisibly increased cost.

[0026] The present invention is further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the present invention. The methods used in the present invention are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0027] Example:

[0028] like Figures 1 to 6 As shown, the utility model provides a new type of bending needle stepping motor, including a casing 1 and a motor output shaft 2, a winding skeleton 3 is installed in the casing 1, the winding skeleton 3 is provided with five pin holes, each pin hole is installed with a bending needle 4, one end of the bending needle 4 is bent to form a bending portion 5, the bending portion 5 is flat, and a terminal wire 6 is welded on the bending portion 5, and an outlet box 7 is installed on the outside of the winding skeleton 3, the outlet box 7 is used to limit the terminal wire 6 to ensure the firmness of the terminal wire 6.

[0029] The terminal wire 6 is directly welded to the bent portion 5 of the bending needle 4, eliminating the circuit board, realizing automatic assembly, and omitting the steps of manually separating the wires and welding them on the circuit board. The operation is more convenient, saving manpower, low cost, and less waste. At the same time, it further reduces the manual error rate and greatly improves production efficiency.

[0030] Furthermore, a gear set is installed above the winding skeleton 3 , the gear set is installed on the mounting plate 22 , the gear set is installed in the housing 1 , and the gear set is connected to the motor output shaft 2 .

[0031] The setting of the gear set can achieve a better deceleration effect on the motor output shaft 2 and increase the torque.

[0032] Furthermore, a rotor magnetic ring 8 is coaxially mounted on the casing 1, and the rotor magnetic ring 8 is inserted into the casing needle 26 inside the casing 1. A gear 1 9 is fixedly mounted on the top of the rotor magnetic ring 8. The gear set includes a gear 2 10, a gear 3 11 and a gear 4 12. The gear 2 10 includes an upper gear 2 101 and a lower gear 2 102. The upper gear 2 101 is fixedly mounted on the lower gear 2 102. The gear 1 9 is meshed with the lower gear 2 102 on the gear 2 10. The upper gear 2 101 of the gear 2 10 is meshed with the gear 3 11. The gear 3 11 is meshed with the gear 4 12. The gear 4 12 is fixedly connected to the motor output shaft 2. Specifically, a gear five 24 is rotatably installed at the bottom of the gear four 12. Since the installation position of the gear three 11 is restricted by the mounting plate 22, the gear three 11 is installed at the boss of the mounting plate 22. Therefore, the setting of the gear five 24 can better enable the gear three 11 to drive the gear four 12 to rotate, thereby raising the gear four 12 and ensuring that the gear three 11 is always engaged with the gear four 12.

[0033] The rotation of the rotor magnetic ring 8 drives the rotation of its top gear 1 9, and the gear 1 9 drives the lower gear 2 102 to rotate through the through hole 23 on the mounting plate 22. The rotation of the lower gear 2 102 drives the rotation of the upper gear 2 101, and then the upper gear 2 101 drives the rotation of the gear 3 11. The rotation of the gear 3 11 drives the rotation of the gear 4 12, and finally drives the motor output shaft 2 to decelerate.

[0034] Furthermore, the outlet box 7 is snap-fitted to the winding frame 3 , so that the outlet box 7 can be quickly installed on the winding frame 3 , and the installation method is simple and quick.

[0035] Furthermore, buckles 13 are provided on both sides of the outlet box 7 , and the protrusions 25 on the buckles 13 are just clamped on both sides of the clamping plates 14 on the winding skeleton 3 , and the clamping plates 14 are fixedly installed on both sides of the winding skeleton 3 .

[0036] Furthermore, an annular plate 15 is installed at the bottom of the outlet box 7 , and the annular plate 15 is inserted into the annular groove 16 of the winding skeleton 3 to enhance the installation stability of the outlet box 7 .

[0037] Furthermore, a partition plate 17 is fixedly installed in the outlet box 7 , and the partition plate 17 is used to separate the terminal wires 6 , so as to better define the positions of the terminal wires 6 .

[0038] Furthermore, a cover plate 18 is fixedly mounted on the upper portion of the housing 1 , and the cover plate 18 is located above the gear set.

[0039] Furthermore, a through slot 19 is formed between the cover plate 18 and the outlet box 7, and the terminal wire 6 passes through the through slot 19, which not only has a good positioning effect, but also saves the step of manually passing the terminal wire 6 through the outlet box 7, thereby improving production efficiency.

[0040] Furthermore, a protrusion 20 is installed in the outlet box 7 near the through-slot 19. The protrusion 20 is inserted into a groove 21 on the clamping plate 14. A passage is left between the protrusion 20 and the groove 21 to facilitate the passage of the terminal wire 6. Specifically, the terminal wire 6 welded to the bent portion 5 is first separated by the action of the partition plate 17, and then passes through the through-slot 19 through the passage, which has a better limiting effect.

[0041] The working principle of this embodiment is as follows:

[0042] One end of the terminal wire 6 is connected to the power supply, and the current is transmitted to the bending part 5 of the bending needle 4 through the terminal wire 6. At this time, the coil on the winding frame 3 generates a magnetic field to rotate the rotor magnetic ring 8. The rotation of the rotor magnetic ring 8 drives the rotation of gear 1 9. Gear 1 9 passes through the through hole 23 on the mounting plate 22 to drive the lower gear 2 102 to rotate. The rotation of the lower gear 2 102 drives the rotation of the upper gear 2 101, and then the upper gear 2 101 drives the gear 3 11 to rotate. The rotation of the gear 3 11 drives the rotation of the gear 4 12, and finally drives the motor output shaft 2 to decelerate.
