8. The workpiece encapsulation system of claim 7, wherein the pick and place mechanism comprises:

the pick-and-place sucker is provided with a turnover shaft which is horizontally arranged;

the rotary driving mechanism is in transmission connection with the hollow picking and placing sucker so as to drive the hollow picking and placing sucker to turn over by taking the turning shaft as an axis; and

the translation mechanism is in transmission connection with the hollowed-out picking and placing sucker to drive the hollowed-out picking and placing sucker to be in reciprocating translation between the first glue coating mechanism and the receiving platform along the conveying direction.

9. The workpiece encapsulation system of claim 8, wherein the middle portion of the pick-and-place chuck has a second hollowed-out portion, the workpiece encapsulation system further comprising:

the lifting platform is positioned between the first glue coating mechanism and the second glue coating mechanism and provided with a bearing surface for bearing the workpiece output by the first glue coating mechanism, and the size of the lifting platform is smaller than that of the second hollow part, so that the pick-and-place sucker can be sleeved in the circumferential direction of the lifting platform; and

and the lifting driving mechanism is in transmission connection with the lifting platform so as to drive the lifting platform to lift.

10. The workpiece encapsulation system of claim 6, wherein the loading straightening mechanism comprises a loading suction cup and a positioning mechanism, the loading suction cup is used for loading the workpiece onto the positioning mechanism, and the positioning mechanism is used for straightening and positioning the workpiece.
