Description

Technical Field

[0001] This utility model belongs to the technical field of winding equipment, and particularly relates to a stator winding device. Background Technology

[0002] The stator is the stationary part of an electric motor or generator. Its main function is to generate a rotating magnetic field. The stator consists of three parts: the stator core, the stator windings, and the frame. The stator core is the magnetic circuit of the generator, the stator windings form the generator's electrical circuit, and the frame is used to fix the core and bear the weight of the rotating parts. Flat wire stator is a type of stator. When winding flat wire stator, a stator winding device is required.

[0003] Existing stator winding devices, when embedding flat copper wires into the stator slots of the stator core, mostly pre-insert the flat copper wires in a ring shape into the external insertion fixture, and then use a subsequent robot to pick up multiple sets of flat copper wires as a whole and insert them into the stator slots. However, traditional winding devices have poor positioning effect on the stator core and cannot perform multi-directional positioning according to the size of the stator core. This causes the stator core to easily move during the winding process, which directly affects the collective embedding of the flat copper wires. Multiple corrections are required, which greatly prolongs the winding time and directly reduces the processing efficiency of the device. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a stator winding device, which solves the problems of poor positioning effect of stator core, inability to perform multi-directional positioning according to the size of stator core, resulting in easy positional movement of stator core during winding process, which directly affects the collective embedding of flat copper wire, requires multiple corrections, greatly prolongs winding time, and directly reduces the processing efficiency of the device.

[0005] This utility model is implemented as follows: a stator winding device includes a placement frame and four sets of T-shaped slides evenly inserted on the placement frame. Each set of T-shaped slides has a slidable locking strip, and a limiting frame is fixed on the locking strip.

[0022] like Figures 1 to 4As shown, the stator winding device provided in this embodiment of the present invention includes a placement frame 1, on which a controller is embedded, and four sets of T-shaped slides 2 evenly inserted on the placement frame 1. Each set of T-shaped slides 2 has a locking strip 7 slidably disposed on it, and a limiting frame 3 is fixed on the locking strip 7. The side of the limiting frame 3 that is close to each other is attached to the outer surface of the stator core, and the inner side of the top of the T-shaped slides 2 is attached to the bottom of the stator core. Each set of T-shaped slides 2 has a T-shaped rod 4 symmetrically inserted on it, one end of which is fixed to the placement frame 1. The first spring 5 is wound around the T-shaped rod 4. The two ends of the first spring 5 are fixed to the protruding end of the T-shaped rod 4 and the T-shaped slide 2. The design of the first spring 5, the T-shaped slide 2 and the limiting frame 3 can place and initially position the stator core. The placement frame 1 is equipped with an anti-movement component that works with the stator core. By setting the anti-movement component, the stator core can be quickly positioned before winding by using multi-directional, multi-position and multi-form positioning methods, which can effectively prevent the stator core from moving and improve winding accuracy and winding efficiency.

[0023] As a preferred embodiment of this utility model, the anti-movement component includes an air pump 13 fixed to one side of the bottom of the placement rack 1. The air inlet of the air pump 13 is connected to a first T-shaped pipe 14, one end of the first T-shaped pipe 14 is connected to a first loop pipe 15 fixed to the placement rack 1 by a support block, the air outlet of the air pump 13 is connected to a second T-shaped pipe 16, one end of the second T-shaped pipe 16 is connected to a second loop pipe 17, an L-shaped plate is fixed to the bottom of each set of clips 7, and an adsorption pipe 20 is inserted into the L-shaped plate. The T-shaped slides 2 have a first groove at their close ends that cooperate with the adsorption pipe 20, and the top end of the adsorption pipe 20 passes through... The sealing ring is attached to the bottom of the stator core. The bottom end of each set of adsorption pipes 20 is connected to a branch pipe 19 that can extend and retract. One end of the branch pipe 19 is connected to the first loop pipe 15. A second spring 21 is wound around each set of adsorption pipes 20. The two ends of the second spring 21 are fixed to the L-shaped plate and the bottom protruding ring of the adsorption pipe 20. The design of the air pump 13, together with the first T-shaped pipe 14, the second T-shaped pipe 16, the first loop pipe 15 and the branch pipe 19, can extract the air in the adsorption pipe 20 and keep it in a negative pressure state so as to adsorb the adsorption pipe 20 to the bottom of the stator core and position the stator core.

[0024] As a preferred embodiment of this utility model, the anti-movement component further includes an auxiliary cylinder 10 that is uniformly fixed to the top of the placement frame 1 by a vertical plate. A piston rod 11 is slidably arranged inside the auxiliary cylinder 10. One end of the piston rod 11 is fixed to the limiting frame 3 by a side plate. A bent pipe 18 is connected to the side of the auxiliary cylinder 10 away from the side plate. One end of the bent pipe 18 is connected to the second loop pipe 17. An exhaust pipe is connected to the outer side of the top and bottom of each set of auxiliary cylinders 10. Solenoid valves 22 are provided on both ends of the first T-shaped pipe 14, the end of the second T-shaped pipe 16 away from the air pump 13 and the second loop pipe 17, one end of the bent pipe 18, and the exhaust pipe. The air pump 13, in conjunction with multiple sets of solenoid valves 22, can change the air inlet and outlet positions of the air pump 13 so as to use the piston rod 11 to squeeze and position the limiting frame 3 and to perform multi-directional positioning of the outer surface of the stator core. At the same time, the design of the exhaust pipe allows the auxiliary piston rod 11 to move freely with the side plate when the gas is not filled into the auxiliary cylinder 10.

[0025] As a preferred embodiment of this utility model, each set of T-shaped slides 2 is provided with a fixed groove 6 and a locking strip 7 is engaged in the fixed groove 6. Each set of locking strips 7 is threaded with a locking bolt 9. Multiple sets of screw holes 8 that are threadedly connected to the locking bolts 9 are evenly provided at the bottom of the inner cavity of the fixed groove 6. The design of the locking bolts 9 and the screw holes 8 can position the moving limit frame 3 so that the position of the limit frame 3 can be freely changed according to the wall thickness of the stator core, making it easy for the device to be adapted to stator cores of different sizes.

[0026] As a preferred embodiment of this utility model, the end of the T-shaped carriage 2 inserted into the placement frame 1 has a cross-shaped structure, which improves the stability of the T-shaped carriage 2 when it moves and prevents it from falling off the placement frame 1.

[0027] As a preferred embodiment of this utility model, multiple sets of U-shaped frames 12 are evenly inserted around the perimeter of the placement rack 1. Both ends of each set of U-shaped frames 12 are fixed to the bottom of the T-shaped slide 2. A second groove is provided on the side of the U-shaped frames 12 that is close to each other, which is used in conjunction with the adsorption pipe 20. The design of the U-shaped frames 12 can help the T-shaped slide 2 move stably and prevent one end from tilting downward due to excessive movement.

[0028] As a preferred embodiment of this utility model, the top of each set of limiting frames 3 has an outward inclined structure, which can help the stator core move down stably and avoid obstruction. Two sets of uprights are symmetrically fixed inside each set of limiting frames 3, which improves the overall strength of the limiting frames 3 and prevents them from breaking easily.

[0029] The working principle of this utility model:

[0030] refer to Figures 1 to 4The user moves the stator core onto the placement rack 1 and lowers it using an external robotic arm. The inclined limiting frame 3 at the top assists in the stable downward movement of the stator core. The force applied to the limiting frame 3 drives the T-shaped slide 2 outward and compresses the first spring 5 until the bottom of the stator core contacts the T-shaped slide 2. The elastic rebound of the first spring 5 then places and initially positions the stator core. As the stator core moves downward, the adsorption pipe 20 moves downward synchronously, stretching the second spring 21. The elastic rebound of the second spring 21 ensures the adsorption pipe 20 is tightly against the bottom of the stator core. The user then activates the solenoid valves 22 on the air pump 13, the bottom of the first T-shaped pipe 14, and the bend pipe 18 via the controller. The air pump 13 then draws external gas through the second loop pipe 17 and the bend pipe... Pipe 18 delivers the material to the auxiliary cylinder 10, thereby providing a certain pushing force to the piston rod 11. The piston rod 11 can then be used to position the limit frame 3, thus enabling multi-directional positioning of the outer surface of the stator core. After positioning is completed, the above-mentioned opening solenoid valve 22 is closed, and another set of solenoid valves 22 on the first T-shaped pipe 14 and the second T-shaped pipe 16 are opened. At this time, the air pump 13 extracts the air from the adsorption pipe 20 through the first loop pipe 15 and the branch pipe 19 and discharges it through the second T-shaped pipe 16, keeping its interior under negative pressure. This allows the adsorption pipe 20 to be adsorbed onto the bottom of the stator core. After adsorption is completed, the above-mentioned opening solenoid valve 22 is closed, and the stator core can be repositioned. This effectively prevents the stator core from shifting, improving the subsequent winding accuracy and winding efficiency.
