Description

Technical Field

[0001] This invention relates to the field of electronic component manufacturing technology, and in particular to an electronic component surface quality inspection, sorting and conveying device. Background Technology

[0002] With the rapid development of the electronics industry, the application range of electronic components is becoming increasingly wide. Their surface quality directly affects the performance and reliability of end products, thus the requirements for the detection and sorting of surface defects in electronic components are constantly increasing. Currently, the surface quality inspection of existing electronic components mostly adopts manual inspection or semi-automatic inspection equipment. Manual inspection is inefficient, labor-intensive, and easily affected by human factors, leading to unstable inspection accuracy. Semi-automatic equipment often suffers from poor coordination between inspection, sorting, and conveying processes. During the sorting process, components are prone to jamming and guide misalignment, making it difficult to adapt to electronic components of different sizes and specifications. At the same time, the guide rails of existing conveying devices lack sufficient support stability. During the conveying process, the rails are prone to shaking, affecting the conveying accuracy of components. Insufficient friction on the surface of the conveyor belt can easily cause components to slip. The speeds of each conveyor belt cannot be flexibly matched, resulting in poor stability of components during the transfer and transition process. This, in turn, affects the overall efficiency and reliability of inspection and sorting, and cannot meet the high-efficiency and precise quality control requirements of electronic components in modern production.
