Description

Technical Field

[0001] The utility model relates to the technical field of flat wire motors, in particular to a head pressing device for winding a flat wire motor. Background Art

[0002] In the actual application of new energy vehicles, as the indicators of high power density and high torque density are getting higher and higher, flat wire with higher slot fill rate has become the first choice in motor design. The main winding forms of flat wire motors are Hair-pin, I-pin, W-Pin, etc. Among them, Hair-pin is shaped like a hairpin. It is first formed, then inserted, and finally welded on one side; I-pin winding is shaped like the letter "I", directly inserted, and then welded on both sides. This method does not require single-slot assembly, which helps to reduce the reserved space for winding assembly. However, the welding process is relatively cumbersome, and the end size is large; W-Pin winding is mainly optimized at the welding end to improve the performance and efficiency of the motor, so W-Pin winding form is more commonly used.

[0003] A Chinese patent with application number 202122989504.9 discloses a winding mechanism for flat wire winding. The winding mechanism disclosed above includes a driving shaft assembly and a driven shaft assembly. The driving shaft assembly has a driving shaft, and the driven shaft assembly has a driven shaft. The driven shaft can be detachably connected to the driving shaft; the driving shaft assembly also includes a driving shaft bracket and a driving shaft driving device. The driving shaft is rotatably mounted on the driving shaft bracket, and the output end of the driving shaft driving device is connected to the driving shaft; an iron core placement seat is provided at the upper end of the driving shaft, and a wire locking assembly and a wire pressing assembly are provided on the driving shaft bracket. A Chinese patent with application number 202121806830.5 discloses a flat wire winding mechanism. The above-disclosed winding mechanism includes a translation drive device, a first lifting drive device, a skeleton material clamp, a wire body material clamp, a rotary lower positioning chuck, a rotary upper positioning chuck, a tangent mechanism and a wire clamping mechanism. The first lifting drive device is installed on the translation drive device, and the rotary upper positioning chuck is installed on the first lifting drive device. The wire body material clamp and the skeleton material clamp are both installed on a second lifting drive device provided on one side of the rotary upper positioning chuck through a mounting block. The skeleton material clamp is located between the rotary upper positioning chuck and the wire body material clamp. The wire clamping part of the wire clamping mechanism is located on the other side of the rotary upper positioning chuck. The rotary lower positioning chuck is located below the rotary upper positioning chuck. The tangent mechanism is installed on the rotary lower positioning chuck and is located on one side of the rotary lower positioning chuck.

[0004] The above-mentioned prior art disclosed does not use a winding machine in the form of W-Pin winding. Since the W-Pin winding form is relatively complicated, the winding is currently performed manually on the market. During manual winding, the head of the wire harness cannot be fixed and pressed, which makes it easy for the head of the wire harness to move during the winding process, affecting the winding work of the wire harness, thereby reducing the winding efficiency and also affecting the quality after winding.
