Description
Technical Field
[0001] The utility model relates to the technical field of motor production, in particular to a semi-automatic pin insertion device for assembling a brushless motor skeleton. Background Art
[0002] Semi-automatic pin insertion devices play a vital role in brushless motor frame assembly, primarily by improving production efficiency, ensuring assembly precision, and reducing the complexity of manual operations. First, from the perspective of improving production efficiency, semi-automatic pin insertion devices automate the pin insertion process, significantly accelerating brushless motor frame assembly. Traditional assembly methods often require workers to manually insert pins into the frame, which is not only time-consuming and labor-intensive but also susceptible to human error, resulting in low production efficiency. Semi-automatic pin insertion devices, by precisely controlling the movement and force of the pins, enable stable and rapid pin insertion, significantly improving overall production line efficiency. Second, semi-automatic pin insertion devices excel in ensuring assembly precision. Brushless motor frame assembly places extremely high demands on pin position and angle; even the slightest deviation can cause motor performance degradation or even malfunction. Through precise design and manufacturing processes, semi-automatic pin insertion devices ensure accurate pin position and angle, thereby improving assembly precision and reliability. Furthermore, semi-automatic pin insertion devices reduce the complexity and labor intensity of manual operations.
[0003] Conventional semi-automatic pin insertion devices for brushless motor frame assembly have shortcomings. First, they cannot reliably clamp brushless motor frames of varying specifications. Second, they cannot rotate the brushless motor frame after clamping it, allowing the multiple pin insertion slots around the perimeter to be sequentially filled with pins. Therefore, improvements are needed. Utility Model Content
