After curing is completed, the water-cooled UV lamp is turned off, and the curing cylinder 48 drives the floating plate 47 to slide upward along the column 45. Then, the prism stage module 4 carries a new set of pre-cured parts on the material tray 24 into the curing platform 44 area. Next, the lifting and distributing linear module 52 drives the clamping plate 51 upward and into the position of the prism stage module 4. At this time, the clamping cylinder 55 drives two... Clamping plate 51 clamps the tray 24 on the prism stage module 4. After clamping, the lifting and distributing linear module 52 drives clamping plate 51 to continue moving upward. Then, the prism stage module 4 disengages from the curing platform 44, and the distributing cylinder 54 drives the intermediate support 53 to move upward, simultaneously moving the tray 24 containing the cured parts upward. The prism stage module 4 then re-enters the curing platform 44. The distributing cylinder 54 resets, and the tray 24 on the intermediate support 53 is fed into the prism stage module 4, where it is then processed by the prism stage module 4. The material is returned to the prism tower 2; finally, the lifting and distributing linear module 52 drives the clamping plate 51 to descend, so that the material tray 24 of the pre-cured parts enters the intermediate support 53. The clamping cylinder 55 drives the clamping plate 51 to move, so that the clamping plate 51 is disengaged from the material tray 24, and the material tray 24 is accurately placed on the intermediate support 53. Finally, the curing cylinder 48 drives the lamp cover 49 to press against the top surface of the curing platform 44. The water-cooled UV lamp inside the lamp cover 49 performs final curing on each row of pre-cured parts on the material tray 24, and so on.
