Description

Technical Field

[0001] The invention relates to a warehouse discharging device, in particular to an electronic material tray discharging device. Background Art

[0002] Electronic materials are the most basic components of electronic products. SMT patch technology is usually used to mount electronic components on PCBA substrates. Electronic materials have a wide variety of types, small device geometry, and different storage environments. Electronic materials are generally stored in plastic discs, and different electronic materials often use similar material discs, which are later called electronic disc materials.

[0003] The current electronic trays can be automatically transported. The material-retrieving device for automatically transporting electronic trays generally uses suction cup suction, overall grasping, side clamping and other methods to take out the stored electronic trays from the storage box, but there are generally problems of low efficiency and low success rate. The suction cup suction method requires that the suction surface must be smooth and flat, but the smooth parts of electronic trays produced by different manufacturers are often inconsistent, which will have a great impact on the reliability of suction, so it is not universal. The overall grasping and side clamping methods require precise control of the range of movement of grasping or clamping, otherwise it is easy to cause damage to the tray or electronic components. The diameter and thickness of electronic trays produced by different manufacturers often differ, which requires real-time adjustment of the range of movement of the grasping mechanism or clamping mechanism according to different trays to avoid damage to the tray or electronic components. This adjustment operation is cumbersome and does not have universality and reliability. Summary of the invention
