Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to a detection device for the pre-torsion of the stator of a flat wire motor. Background Technology

[0002] In the stator manufacturing process of flat wire motors, flaring and twisting are two crucial steps. The quality of flaring directly affects the pass rate of twisting before mold entry. Therefore, in automated production lines, the inspection after flaring and before twisting is particularly important and a key means to improve the pass rate. Currently, one method for inspection on domestic automated flat wire production lines is to add a manual inspection station after the flaring process, using inspection molds to manually check the flaring quality. This method increases labor costs and has relatively low efficiency, hindering automation. Another method is to omit this step, allowing the motor to directly enter the twisting process after flaring. The disadvantages of this approach are a lower pass rate, increased costs, and difficulty in controlling equipment costs. Summary of the Invention

[0003] In order to overcome the shortcomings of the above-mentioned technologies, this invention provides a device for detecting the pre-torsion of the stator of a flat wire motor.

[0004] The technical solution of this utility model is as follows: a pressure sensor is provided in the center of the base frame, linear bearings are provided around the base frame, a sliding rod slides in the linear bearings, the top of the sliding rod is fixedly connected to the upper plate, a detection mold is provided on the upper plate, a guide core is provided on the detection mold, and a pressure display cooperates with the pressure sensor and is fixedly connected to the base frame. Beneficial effects

[0005] Because it adopts a flat wire motor stator pre-torsion detection device, a reasonable pressure range is set by a pressure sensor to detect the quality of the flaring. It can not only detect and shape the stator before torsion, but also detect stators with poor flaring and repair them. It has the advantages of simple and effective operation and cost saving.

[0010] refer to Figure 1 , Figure 2 A device for detecting the torsion of a flat wire motor stator before it twists and turns, wherein a pressure sensor 2 is provided at the center of a base frame 1, linear bearings 3 are provided around the base frame 1, a sliding rod 4 slides in the linear bearings 3, the top of the sliding rod 4 is fixedly connected to an upper plate 5, a detection mold 6 is provided on the upper plate 5, a guide core 7 is provided on the detection mold 6, and a pressure display 8 cooperates with the pressure sensor 2 and is fixedly connected to the base frame 1.

[0011] The steps of the working method are as follows:

[0012] The flat wire stator to be inspected after flaring is fed into the inspection mold 6 by a robotic arm or similar means. The pressure sensor 2 senses the pressure and outputs the pressure value through the pressure display 8. The pressure value is automatically compared with the set pressure value. If the pressure value exceeds the set pressure value, the pressure display alarms, and the robotic arm automatically removes the unqualified product. This achieves the function of automatically detecting the quality of flaring and preparing for stator torsion.
