Description

Technical Field

[0001] This utility model relates to the field of winding device technology, specifically a polyester glass tape winding device for stator coil production. Background Technology

[0002] Wind turbine motors are one of the core components of wind power generation systems, primarily used to convert wind energy into electrical energy. They are characterized by high reliability, low speed and high torque, and wide speed range. In high-power motors such as wind turbine motors, due to the large current, copper bars can better carry the large current, reduce resistance loss, and improve the efficiency and reliability of the motor. At the same time, copper bars have high mechanical strength and can withstand large electromagnetic forces and mechanical stresses. To enhance the insulation performance of the stator copper bar coils of wind turbine motors, insulating polyester glass tape is wound around their surface using a winding device.

[0003] The existing patent publication number CN219678282U discloses an auxiliary tool for wrapping polyester fiberglass tape around the stator core of a hydro-generator stator. This tool includes two supports and a crank handle. The two ends of the stator core are placed on the two supports, and the crank handle is threaded onto one end of the stator core. This utility model has a reasonable structural design. By setting up supports and a crank handle, one person can manually rotate the stator core placed between the two supports while another person holds the polyester fiberglass tape, allowing it to be wrapped around the stator core automatically. This greatly improves work efficiency, reduces personnel and facility costs, shortens work time, and is simple, convenient, economical, and practical. However, this wrapping auxiliary tool requires one person to operate the component to be wrapped with polyester fiberglass tape while another person holds the tape to complete the wrapping work. This method is inefficient. Therefore, we propose a polyester fiberglass tape wrapping device for stator coil production to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention discloses a polyester glass tape winding device for stator coil production, including a support platform 1, a mounting base 2 fixed to the top of the support platform 1, an annular plate 3 rotatably connected to one side wall of the mounting base 2, a clamping rod 4 for fixing the polyester glass tape roll fixed to one side wall of the annular plate 3, a rotating shaft 5 rotatably connected to the side wall of the mounting base 2 via a bearing, a driving gear 6 fixed to the surface of the rotating shaft 5, a driven gear ring 7 fixed to one side wall of the annular plate 3, the driven gear ring 7 meshing with the driving gear 6, and guide seats 8 fixed to the top of the support platform 1 on both sides of the mounting base 2. Each guide seat 8 is rotatably connected to a drive roller 9 via bearings. A sprocket 17 is fixed to the surface of each drive roller 9, and the two sprockets 17 are connected by a chain 18, allowing both drive rollers 9 to rotate simultaneously under the action of a single motor, thus saving production costs. A connecting plate 10 is fixed to one side wall of each guide seat 8. The top of each connecting plate 10 is rotatably connected to two limiting rollers 11 for guiding the stator coils during transport, via bearings. The limiting rollers 11 facilitate limiting the forward and backward position of the stator copper strip coils during transport, preventing... The deviation affects the winding of the polyester glass strip. An auxiliary roller assembly 12, which works in conjunction with the two drive rollers 9, is installed above the mounting base 2. Two sets of extension roller assemblies 13 are installed on the top of the support platform 1. During the polyester glass strip winding process for stator coil production, after the polyester glass strip roll is limited and installed on the clamping rod 4, the stator copper strip coil can be placed on the right-side extension roller assembly 13 and drive roller 9. When one end of the stator copper strip coil passes through the annular plate 3, one end of the polyester glass strip can be fixed to the stator copper strip coil. This facilitates the movement of the stator copper strip coil by the drive roller 9. At this time, the auxiliary roller assembly 12 can be moved down to limit the upper part of the stator copper strip coil. Then, the motor is started to drive the drive roller 9 to rotate, which can transport the stator copper strip coil. At the same time, the motor can be started to drive the rotating shaft 5 to rotate. After the rotating shaft 5 rotates, it can drive the driven gear ring 7 to rotate under the cooperation of the drive gear 6. After the driven gear ring 7 rotates, it can drive the ring plate 3 to rotate. When the ring plate 3 rotates, it will drive the polyester glass strip on the clamping rod 4 to rotate around the moving stator copper strip coil. At this time, when the stator copper strip coil is transported from the right side to the left side, the polyester glass strip can be wrapped around its surface.

[0024] like Figure 1 and Figure 2As shown, in some embodiments, the auxiliary roller assembly 12 includes a bracket 1201 fixed to the top of two guide seats 8. A cylinder 1202 is fixed to the top of the bracket 1201. The ejector end of the cylinder 1202 slides through the bracket 1201, extends below it, and is fixed to a movable seat 1203. Two rollers 1204 are rotatably connected between the inner walls of the two sides of the movable seat 1203 via bearings. Two guide rods 1205 slide through the top of the bracket 1201, and the bottom ends of the guide rods 1205 are fixed to the movable seat 1203. When connected and in use, the starting cylinder 1202 can drive the moving seat 1203 to move down. After the moving seat 1203 moves down, it will drive the two rollers 1204 to move down. When the two rollers 1204 move down, they will be located above the drive roller 9. At this time, it can play a limiting role above the stator copper bar coil during conveying, so that the drive roller 9 can drive it to move more smoothly. The two guide rods 1205 can guide the moving seat 1203, so that it will be more stable during the up and down movement.

[0025] like Figure 1 and Figure 2 As shown, in some embodiments, the extension roller assembly 13 includes a positioning seat 1301 fixed to the top of the support platform 1. Both sides of the positioning seat 1301 are rotatably connected to rotating rods 1302 via bearings. A frame 1303 is fixed between the two rotating rods 1302. Transmission rollers 1304 are rotatably connected at equal intervals between the inner walls of the two sides of the frame 1303 via bearings. Two bearing plates 1305 are fixed to the top of the positioning seat 1301 for supporting and limiting the frame 1303 after it is flipped. In use, after the frame 1303 is laid flat, the equally spaced transmission rollers 1304 will also be in a flat state. Thus, when the stator copper bar coil is being transported and moved, it can support it. When it needs to be folded, the frame 1303 only needs to be rotated to fit against the bearing plate 1305. At this time, the bearing plate 1305 can support the rotated and folded frame 1303.

[0026] like Figure 3 As shown, in some embodiments, a T-shaped limiting rod 14 is inserted into one end of the locking rod 4, and a cathode magnet 15 is fixed to one end of the T-shaped limiting rod 14. An anode magnet 16 is fixed inside the insertion hole at one end of the locking rod 4. The cathode magnet 15 and the anode magnet 16 attract each other. In use, after the polyester glass tape roll is sleeved on the surface of the locking rod 4, the polyester glass tape roll can be limited by inserting the T-shaped limiting rod 14 into the locking rod 4 to prevent the polyester glass tape roll from falling off during rotation. With the cooperation of the cathode magnet 15 and the anode magnet 16, the T-shaped limiting rod 14 and the locking rod 4 are fixed by magnetic attraction, which makes it more convenient to replace the polyester glass tape roll after use.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
