Description

[0002] Electronic component is the basic component of electronic circuit, and it plays a key role in the function and performance of electronic products. With the rapid development of electronic products, the identification and traceability of electronic components become increasingly important. During the production, transportation, sales and after-sales service of electronic components, identification is often required to facilitate management and maintenance. These identifications usually include model number, batch number, production date and bar code information. Therefore, a coding machine for electronic components is needed.
[0003] During the coding process of electronic components, using a conveyor belt system for mobile coding is a common solution. However, the conventional electronic components moving on the conveyor belt lack effective limiting devices, which makes the components prone to positional deviation due to vibration, friction or other external factors during transportation. Positional deviation not only leads to inconsistent coding positions, but also may cause some components to completely miss the coding equipment, resulting in failure to code, which may lead to subsequent management and traceability difficulties, increasing the risk of errors in the production process. The conventional coding machine usually does not have a cooling function during operation. However, the materials of some electronic components are very sensitive to temperature. During the laser coding process, the heat generated by the laser beam may cause these materials to deform, melt or burn, thereby affecting the performance and appearance of the components, reducing the practicality of the device.
