Description

Technical Field

[0001] The invention relates to stator winding equipment, in particular to a three-wire nozzle servo inner winding machine. Background Art

[0002] The stators of motors are all equipped with copper wire windings, so the stator body needs to be wound and embedded. At present, the known winding technologies are all single-needle double-station winding, which is slow, inefficient, and cannot be wound at high speed. The main difficulties are high speed, large vibration, easy wire breakage, poor winding stability after high speed, and the output cannot be greatly improved. Traditional winding technology can only wind one slot stator at a time, and cannot wind multiple slots at the same time. It is inefficient and time-consuming, especially for stators with a large number of turns. It takes at least 10 minutes to wind a stator with 12 slots and 230 turns. Mass production has low production capacity. At present, the industry handles the bridge wire during the winding process by moving the motor wire nozzle and wrapping the wire around the stator frame or the wire column.

[0022] like Figures 1 to 6As shown, a three-wire nozzle servo inner winding machine includes a stator winding positioning mechanism, a gear box structure is provided below the stator winding positioning mechanism, a stator is installed between the stator winding positioning mechanism and the gear box structure, and the gear box structure includes a gear box 1, and a wire arrangement mechanism and a swing mechanism are provided in the gear box 1;

[0023] The wire arrangement mechanism comprises two main shafts 2, the ends of the main shafts 2 are connected to the bevel gear 3 and the main shaft slider 4, the main shaft slider 4 is connected to the upper flying fork rod 5 and the lower flying fork rod 6, and the outer side of the lower flying fork rod 6 is sleeved with a wire arrangement driven gear 7 and a wire arrangement gear 8 meshing with the wire arrangement driven gear 7;

[0024] The swing mechanism includes two main shaft synchronous wheels 9, which are connected to a swing adjustment screw 10. A driving gear 11 is provided on the outer side of the swing adjustment screw 10. The driving gear 11 meshes with an intermediate gear 12, and the intermediate gear 12 meshes with a driven gear 13. The driven gear 13 is connected to a cam 14 through a shaft. The ends of the swing adjustment screw 10 are connected to an upper flying fork rod 5 and a lower flying fork rod 6.

[0025] Furthermore, an upper flying fork rod guide sleeve 15 and a lower flying fork rod guide sleeve 16 are provided at the top and bottom of the gear box body 1 , and the end of the upper flying fork rod 5 passes through the upper flying fork rod guide sleeve 15 , and the lower flying fork rod 6 passes through the lower flying fork rod guide sleeve 16 .

[0026] The interiors of the upper flying fork rod 5 and the lower flying fork rod 6 are hollow, and the end of the lower flying fork rod 6 is provided with a wire nozzle 17.

[0027] The stator winding positioning mechanism comprises a positioning plate 18 , the stator is placed in the middle of the positioning plate 18 , a stator pressing sleeve 19 is provided above the positioning plate 18 , and the stator pressing sleeve 19 is connected to a pressing cylinder 20 .

[0028] A wire hooking cylinder 21 is provided on the outer side of the stator on the positioning plate 18, and the end of the wire hooking cylinder 21 is connected to the wire hook. A rotation indexing motor 22 is provided on the positioning plate 18, and the rotation indexing motor 22 is connected to a rotating disk 23. The rotating disk 23 is located at the bottom of the stator. A stator handling robot 24 is provided on one side of the stator winding positioning mechanism.

[0029] During the winding process, the servo motor drives the main shaft to rotate. Due to the meshing of the gears, the corresponding intermediate gear drives the driven gear to rotate. The main shaft slider 4 drives the upper flying fork rod 5 to slide up and down. At the same time, the cam 14 rotates, driving the swing adjustment screw 10 to make a corresponding angle. While moving up and down, the lower flying fork rod 6 swings back and forth together. The copper wire of the lower flying fork rod 6 will be hung on the stator core. While winding, the wire arrangement motor drives the wire arrangement gear 8 to evenly arrange each copper wire in the motor slot according to the specified coordinate value. Through the control of the servo tensioner, each wire will not cross or overlap, thereby effectively ensuring that the resistance value is within the designed range;

[0030] After each groove is wound, the clamping cylinder 20 rises, the indexing motor 22 drives the rotating disk 23 to index the stator core, the wire hooking cylinder 21 hooks the wire, and after it is hung on the wire end plate, the wire hooking cylinder 21 retracts, and the clamping cylinder 20 is pressed down to continue to repeat the winding. When all the grooves are wound, the wire is hooked, the lead wire is cut, all cylinders are reset, and the cycle is ready to wind the next stator.

[0031] The mechanism reduces the output speed and increases the torque according to different ratios. The gear box 1 is divided into spur gears and helical gears. Since the helical gears have a certain angle, they can be adjusted to different lengths. The length size can adapt to different stacking thickness requirements.

[0032] The driving gear 11 is a straight tooth. When the driven gear 13 moves, the cam 14 moves accordingly. The lift and return stroke of the cam mechanism correspond to the division of each slot of the stator core. For example, for a 12-slot stator, the division of each slot is 360 / 12=30 degrees. The angle corresponding to the lift and return stroke of the cam 14 is 30 degrees. The lift and return stroke curves of the cam are plotted by Archimedean spiral calculations. The motion effect is smooth and stable. It is driven by a 4.4KW Yaskawa servo motor with controllable speed and accurate position accuracy. As we all know, the servo motor rotor is controlled by the input signal and can respond quickly. It is widely used in automatic control systems.

[0033] The electronic control part of this device uses imported components. The main controller is the Yaskawa motion controller MP2300S, which is a small motion controller with a multifunctional structure design that integrates power supply function, CPU function, I / O function and communication function. The main controller can transform the predetermined control scheme and planning instructions into the desired mechanical motion under complex conditions, and realize the precise position control, speed control, acceleration control, torque or force control of the mechanical motion.

[0034] Using bus control, there will be no pulse loss during the motion process like the traditional pulse servo, which can ensure the accuracy of each servo division. This type of motion controller uses DSP and FPGA as the core processor. The DSP chip is used as the core processor of the motion controller, and the PC is used as the information processing platform. The motion controller is embedded in the PC in the form of a plug-in card, that is, the "PC + motion controller" mode. In this way, the information processing capability and open characteristics of the PC are organically combined with the motion trajectory control capability of the motion controller, which has the characteristics of strong information processing capability, high degree of openness, accurate motion trajectory control, and good versatility. This type of controller makes full use of the high-speed data processing capability of DSP and the super logic processing capability of FPGA, which is convenient for designing a motion controller with complete functions and superior performance. This type of motion controller usually provides multi-axis coordinated motion control and complex motion trajectory planning, real-time interpolation calculation, error compensation, servo filtering algorithm on the board, and can achieve closed-loop control.

[0035] The winding speed is greatly increased by using this device, and the customer's production capacity can be greatly improved; the precise winding process reduces the occurrence of defective products, thereby effectively reducing costs; effective shock absorption can reduce the noise intensity in the production workshop and is more ergonomically designed.
