AI Technical Summary
In traditional motor assembly, wave spring feeding relies on manual labor or simple vibration feeding devices, which suffers from problems such as low efficiency, large errors, frequent jamming, low space utilization, high noise, and poor versatility, making it difficult to meet the needs of efficient and precise automated production.
The pneumatic feeding mechanism includes a vibratory plate, a linear vibrator, a feeding assembly, and a picking assembly. It achieves precise positioning and removal of excess material through negative pressure adsorption and positive pressure blowing of the air hole structure. Combined with the return track, it forms a material circulation. The lifting and rotating components are used to adjust the posture to ensure orderly material conveying and assembly accuracy.
It improves feeding efficiency and stability, reduces waste, adapts to the assembly requirements of stators of different specifications, enhances the accuracy and consistency of motor assembly, reduces energy consumption and noise, and extends the service life of the equipment.
