‌The camera system of Sony SMT plays a vital role in the SMT process, mainly including parts identification and correction functions. ‌

Working principle and function of camera system

The camera system of Sony SMT accurately identifies and locates electronic components through high-resolution cameras and image processing technology. Specifically, the workflow of the camera system includes the following steps:

‌Suctioning chips‌: sucking components from the feeder through vacuum adsorption.

‌Correction‌: using the parts camera to identify the center offset and deflection of the components, and correcting them through the XY axis and RN axis.

‌Blowing chips‌: driven by the electromagnetic joystick, the nozzle places the components on the PCB board‌.

Differences in camera systems of different models of SMT machines

Different models of Sony SMT machines also differ in camera systems. For example, the SI-G200 model is equipped with two high-speed planetary SMT connectors, which can handle electronic components ranging from extremely small to large irregular shapes, with a placement accuracy of up to 40μ, 3σ‌1. The SI-F130 model has a high-precision placement head that can handle components ranging from 0402 to 12mm IC with a placement accuracy of 50μ‌.

Technical parameters and maintenance of the camera system

The camera system of the Sony placement machine performs well in technical parameters. For example, the placement speed of the SI-G200 can reach 45,000cph and the placement accuracy is 45μ, 3σ‌1. In daily maintenance, it is necessary to regularly clean the lens and check the image processing system to ensure its normal operation. In addition, regular calibration and lubrication are also important measures to maintain the high precision of the camera system‌.

In summary, the camera system of the Sony placement machine ensures the accuracy and efficiency of the placement process through high-precision image processing and correction functions, and is an indispensable key equipment in modern electronic manufacturing.
