8. An automated contact lens sealing machine according to claim 1, characterized in that, The product information detection unit (800) includes a detection frame (801) and a product detection camera (802) installed on the detection frame (801). During inspection, after the laser engraving unit (700) laser-marks the packaged product, the product inspection camera (802) is positioned above the material turntable (200) to inspect the marking information of the packaged product.

9. An automated contact lens sealing machine according to claim 1, characterized in that, The sealing detection unit (900) includes a camera driving device (902), a detection rotation mechanism (903), a sealing detection camera (901) driven and connected to the execution end of the camera driving device (902), and a detection pick-and-place mechanism (904) installed at the execution end of the detection rotation mechanism (903). During operation, after the laser engraving unit (700) laser marks the packaged product, the detection and pick-up mechanism (904) picks up the packaged product from the packaged carrier (210) on the material turntable (200). Then, the detection rotation mechanism (903) drives the detection and pick-up mechanism (904) to rotate, placing the heat seal of the packaged product to be detected above the sealing detection camera (901). The camera drive device (902) drives the sealing detection camera (901) to move in order to obtain complete information on the heat seal of the packaged product.

10. An automated contact lens sealing machine according to claim 1, characterized in that, The unloading unit (1000) includes an unloading and conveying mechanism, an unloading and storage frame (1001), and a guide chute (1002). During unloading, the unloading and handling mechanism will transport the sealed products detected by the product information detection unit (800) and the sealing detection unit (900) from the sealing carrier (210) on the loading turntable (200) to the unloading storage box (1001) or send them into the guide chute (1002) as needed. Alternatively, the unloading unit (1000) may include an unloading and conveying mechanism and an unloading guide plate (1011). The unloading guide plate (1011) is provided with at least two unloading guide strips (1012). Adjacent unloading guide strips (1012) form a discharge trough. The unloading and conveying mechanism will transport the packaged products to the corresponding discharge trough as needed after the product information detection unit (800) and sealing detection unit (900) have detected them.

11. An automated contact lens sealing machine according to claim 1, characterized in that, The injection unit (300) includes a peristaltic pump mechanism and an injection head component; the peristaltic pump mechanism controls the liquid in the infusion tube to be injected into the sealing box in the sealing carrier (210) through the injection head component; The heat sealing unit (600) includes a heating component (601), a lifting motor component (602), a lower sealing component (603), an upper lifting component (604), and an upper lifting cylinder (605). The heating component (601) heats the lower sealing component (603), the upper lifting cylinder (605) drives the upper lifting component (604) to rise, and the lifting motor component (602) drives the lower sealing component (603) to fall while simultaneously heat sealing the aluminum foil, so that the aluminum foil and the packaging box are heat-sealed to form a packaged product. The laser engraving unit (700) includes a laser engraving machine body (701), a laser engraving lens assembly (702), and a smoke collection assembly (703); the laser engraving machine body (701) generates energy to perform laser engraving on the surface of the packaged product through the laser engraving lens assembly (702), and the smoke collection assembly (703) collects and discharges the smoke and exhaust gas generated during the operation.
