[0022] Compared with the prior art, the present invention provides an automatic demoulding and contact lens removal machine, which has the following beneficial effects:
[0023] 1. The automatic demoulding and contact lens machine, when working, manually puts the mold parts of the contact lens into the automatic feeding device, the automatic feeding device automatically arranges the upper and lower mold parts, and arranges them on the receiving plate of the demoulding device, the feeding fork mechanism automatically divides the two workpieces to the bottom of the punch head, the guide mechanism is lifted and inserted into the upper mold, the punching cylinder is pressed down, and the upper and lower molds are separated under the action of the buffer spring, and then the guide mechanism is lowered to put the upper mold on the guide groove of the upper mold feeding mechanism; the lower mold after mold separation is waste, the lower mold is squeezed by the feeding fork mechanism, flows into the lower mold slide groove along the arc groove of the receiving plate, and then slides to the waste box, the contact lens is automatically arranged by the upper mold feeding mechanism together with the upper mold to the turntable of the cutting device, and the rotary motor drives the rotating The gear rotates, bringing the upper die into the gap between the rotating gear and the fixed gear, and the cutter cuts the residual material on the side of the upper die. The upper die rotates under the action of the rotating gear and the fixed gear, thereby rotating and cutting the residual material on the entire side circumference of the upper die. While cutting the residual material, the air blower blows air, and the dust box sucks air under the action of the external vacuum cleaner to remove the cut residual material; the turntable of the residual material cutting device rotates to drive the upper die to the front end of the dividing device, and the conveying drive motor drives the conveyor belt to transfer the upper die to the dividing position. The fork driving cylinder drives the dividing fork to divide 10 upper dies at equal intervals. After the division, the fork driving cylinder retracts. The spacing between the 10 upper dies is equal to the spacing between 10 holes in a row of the stepping grid plate. The material picking telescopic cylinder drives the material picking lifting cylinder and the material picking vacuum suction cup to extend together, and the material is picked up. The material lifting cylinder drives the material picking vacuum suction cup to descend and absorb the 10 separated upper molds, and then the material picking lifting cylinder retracts. After the material picking telescopic cylinder retracts into place, the material picking lifting cylinder drives the material picking vacuum suction cup to descend again to place the 10 upper molds into a row of slots on the heating plate, and the material prying cylinder drives the material prying plate to advance one position, and the material prying cylinder drives the material prying plate to return to its original position. At this time, a row of upper molds has advanced one position, and the upper molds are pushed forward on the heating plate in turn. The upper molds slide on the heating plate, and the heating plate is heated by the heating rod, so as to heat and soften the upper molds, which is convenient for the subsequent lens separation device to extrude the lenses. When there is material in the last row of the heating plate, the rear material picking device absorbs this row of materials and places them on the upper mold support plate, and then the extrusion drive motor drives the moving rack to extrude the upper mold forward to the solid state. After the upper mold is squeezed and deformed to a certain extent on the fixed rack, the translation drive motor drives the extrusion drive motor and the mobile rack to translate together. The upper mold rotates under the action of the fixed rack and the mobile rack, so that the lens is evenly stressed all around and thus detaches from the curved surface of the upper mold.

After the lens transfer suction cup absorbs the contact lens, the upper mold drive cylinder drives the upper mold support plate to retract, and the extrusion drive motor drives the mobile rack to retract at the same time. At this time, the upper mold that has taken the lens will fall from the bottom of the upper mold support plate and fall into the upper mold funnel.

The card tray cylinder initially holds the pallet, the empty pallet lifting drive motor moves upward to lift the empty lens placement tray, and then the card tray cylinder retracts. After the empty pallet lifting drive motor descends to the height of one pallet, the card tray cylinder extends out to hold the pallet again, and the empty pallet lifting drive motor continues to descend, placing the bottom row of lens placement trays on the belt conveyor line, and the belt drive motor drives the belt to rotate to transport the lens placement tray The lens is sent to the block position of the conveyor line blocking cylinder, the conveyor line stops, and the lens transfer device starts to place lenses. After the lens placement tray is full, the conveyor line blocking cylinder drops, and the belt drive motor drives the belt to rotate to transport the lens placement tray to the bottom of the receiving tray guide slot. The conveyor line stops rotating, and the receiving tray lifting drive motor moves upward to lift the lens placement tray. When it approaches the card tray cylinder, the receiving tray lifting drive motor pauses, and the card tray cylinder retracts at the same time. The receiving tray lifting drive motor drives the lens placement tray to continue to move upward by the height of a tray, and then the card tray cylinder extends, and the receiving tray lifting drive motor retracts to its original position. After the lens placement tray in the receiving tray guide slot is full, the stacked lens placement trays are manually taken out. BRIEF DESCRIPTION OF THE DRAWINGS
