Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor conveying, and in particular to a semiconductor packaging conveying device with a protective structure. Background Art

[0002] Semiconductors are material products usually composed of silicon, which have higher conductivity than insulators such as glass, but lower conductivity than pure conductors such as copper or aluminum. Their conductivity and other properties can be changed by introducing impurities (called doping) to meet the specific needs of the electronic components in which they reside.

[0017] (2) In the present invention, when the conveyor belt contacts the semiconductor package, the semiconductor package is moved by the conveyor belt, so that the conveyor belt rotates around the rotating rod to prevent the semiconductor package from getting stuck during transportation, and the reaction force of the semiconductor package causes the conveyor belt to drive the rotating rod to move upward, the rotating rod drives the square shell to move upward, the square shell drives the sliding rod to move upward, and at the same time the square shell drives the bending rod to move upward, and the bending rod drives the sliding block to move upward.

[0043] When the conveyor belt 665 comes into contact with the semiconductor package, the conveyor belt 63 drives the semiconductor package to move, so that the conveyor belt 665 rotates around the rotating rod 664 to prevent the semiconductor package from getting stuck during transportation, and the reaction force of the semiconductor package causes the conveyor belt 665 to drive the rotating rod 664 to move upward, the rotating rod 664 drives the square shell 663 to move upward, the square shell 663 drives the sliding rod 661 to move upward, and at the same time the square shell 663 drives the bending rod 671 to move upward, the bending rod 671 drives the sliding block 672 to move upward, and at this time the fixed platform 656 and the square shell 663 are connected. 3 are brought closer to each other, so that the rotating bar 673 can drive the sliding block 672 to move along the outer wall of the bent rod 671, and the sliding block 672 drives the bent plate 674 to move.
