Description

Technical Field

[0001] The invention relates to the technical field of motor manufacturing, in particular to an automatic wire binding machine for a motor stator. Background Art

[0002] When manufacturing the stator of a motor, you first need to make the stator core of the motor stator and wind multiple coils. Then, embed the coils into the grooves of the stator core manually or using a coil embedding machine, insulate the coils, and finally perform injection molding on the stator core with the coils. Common stator binding wire binding methods generally use three methods: 1. Manually use a thin rope to pass through the narrow gap between the stator wire package and the core for binding and fixing; 2. Manually use a piece of tape to pass through the narrow gap between the stator wire package and the core for pasting and fixing; 3. Manually use a cable tie to pass through the narrow gap between the stator wire package and the core for binding and fixing. These three methods have low production efficiency and require a high level of proficiency of the operator.

[0003] Someone has designed an automatic wire binding device for this situation. The wire binding is achieved through a series of actions such as the rotation and advance and retreat of the wire hook needle in coordination with the up and down movement and self-rotation and swing of the wire outlet head.

In order to thoroughly understand the present invention, some specific details will be involved in the following description. In the absence of these specific details, the invention can still be implemented, that is, those skilled in the art can use these descriptions and statements here to more effectively introduce the essence of their work to other technicians in the field.

[0023] Reference Figure 1 , Figure 2 , Figure 3 A motor stator wire binding machine includes a wire binding module composed of a wire hooking needle 1 and a wire passing tube 2, wherein the shapes and basic working principles of the wire hooking needle 1 and the wire passing tube 2 can refer to similar wire binding machines and will not be repeated here.

[0024] It also includes a swing arm 3 and a horizontally rotating cam plate 4, wherein the rotating shaft of the swing arm 3 is located at the front end, and a guide ball is arranged in the middle of the swing arm 3 corresponding to the guide groove of the cam plate 4, that is, when the cam plate 4 rotates, it can drive the swing arm 3 to swing up and down.

[0025] A thread hooking rod sliding member 11 and a thread passing tube sliding member 21 are provided on the rear side of the swing arm 3, and a thread hooking rod sliding member 11 and a thread passing tube sliding member 21 are respectively provided with a thread hooking rod 12 and a thread passing rod 22, and the thread hooking needle 1 and the thread passing tube 2 are respectively installed at the front ends of the thread hooking rod 12 and the thread passing rod 22, that is, when the swing arm 3 swings, the thread hooking needle 1 and the thread passing tube 2 also swing accordingly.

[0026] The thread tube 2 is L-shaped, and a telescopic structure 5 is provided at the rear side of the thread hooking rod 12 to control the forward and backward movement of the thread hooking rod 12. A swinging structure 6 is provided at the rear side of the thread rod 22 to control the rotation of the thread rod 22, so that the cotton thread at the thread tube 2 can be more easily hooked by the thread hooking needle 1 by swinging left and right when the thread tube 2 is discharged. Since the method of driving the thread tube 2 to swing by the rotation of the thread rod 22 has lower requirements on the control structure, it is conducive to reducing the manufacturing cost and maintenance cost of the equipment.

In the process of binding wires, the cam plate 4 drives the swing arm 3 to swing up and down, and the wire hook needle 1 and the wire passing tube 2 move up and down to bind the wires. At this time, the adjustment wheel 76 moves up and down to adjust the wire feeding to ensure that the wire outlet speed at the wire passing tube 2 is moderate. The thread passing wheel group 72 includes a first thread passing guide wheel 721, an auxiliary limiting wheel 722, a main limiting wheel 723, and a second thread passing guide wheel 724 in sequence, wherein the auxiliary limiting wheel 722 is provided with an auxiliary limiting clamping block 725 and a spring, and the main limiting wheel 723 is provided with a main limiting block 726, a spring, and a main limiting block cylinder 727 for controlling the activity of the main limiting block 726. When the thread is not tied, the main limiting wheel 723 clamps the thread. When the hook needle 1 and the thread passing tube 2 are active to tie the thread, the main limiting block cylinder 727 of the main limiting wheel 723 controls the main limiting block 726 to loosen, and only the spring of the auxiliary limiting wheel 722 and the auxiliary limiting clamping block 725 clamp the thread. In this way, it can be ensured that the cotton thread at the thread passing wheel group 72 is in a suitable tightening state regardless of whether it is in the process of tying the thread or the gap between tying the thread.

[0028] A vertical sensor bracket 78 is disposed between the line-out wheel 71 and the line-passing wheel assembly 72 . A sensor 781 is disposed on the vertical sensor bracket 78 . A spring is built into the vertical sensor bracket 78 and connected to the sensor 781 .

After the wire is tied, the wire cutter rod 82 of the wire cutter 8 extends, and the cutter head 83 melts the cotton thread toward the cotton thread between the hooking needle 1 and the workpiece. This design does not require the hooking needle 1 and the wire tube 2 to perform too complicated actions, and the cutter head 83 can accurately melt the cotton thread, thereby improving the wire breaking efficiency.

[0030] The end of the cutter head 83 is provided with an inclined surface 84 to form a blade-like structure to improve the efficiency of the fuse. The wire cutter 8 also includes a cantilever bracket 85, on which a wire cutter bar guide block 86 is provided.

[0031] It also includes a stator positioning disk 9, and the wire binding modules are arranged on the upper and lower sides of the stator positioning disk 9 to achieve wire binding on both sides of the stator at the same time. A positioning disk motor 91 is arranged next to the stator positioning disk 9 to control the rotation of the stator positioning disk 9, and a positioning disk sliding plate 92 is arranged on the lower side of the stator positioning disk 9 to drive the stator positioning disk 9 to move forward and backward. The swing structure 6 at the rear end of the wire rod 22 includes a swing rod 61 connected to the wire rod 22, a horizontal pull rod 62, a horizontal swing rod 63, and a rotatable main control vertical rod 64 to control the flexible rotation of the wire rod 22. It also includes a reset motor 93 and a reset lifting plate 94 to control the overall lifting of the wire binding module, especially to facilitate the wire cutting knife 3 to cut the wire during the wire breaking stage.
