The pressing head 422 and the heating block 333 are heated to heat the adhesive on the lens 200 and melt the adhesive, so as to press the lens 200 and the workpiece 300.
After the lens 200 and the workpiece 300 are bonded, the bonding unit 42 moves away from the workpiece 300, the cover 343 is no longer bonded to the workpiece 300, and the second driving component 332 drives the first wedge-shaped block 3322 to move, so that the second wedge-shaped block 3323 drives the heating block 333 and the supporting block 334 to move downward along the Z direction. After each mechanism is reset, the workpiece 300 can be taken out, and if the next lens 200 and workpiece 300 are to be assembled, the above steps are repeated.
