Description

Technical Field

[0001] This utility model relates to the field of automated production technology of contact lenses, specifically a dry contact lens feeding device. Background Technology

[0002] In the production of colored contact lenses, the conventional process of printing lens patterns involves printing the pattern into a mold and then molding the liquid material in the mold to achieve the printing effect. In the production process of contact lenses, the pre-hydration soaking process is mold separation and lens removal, which is to remove the molded dry contact lens from the mold. The dry lens is more stable in terms of shape and size.

[0003] Dry lens printing is a special contact lens manufacturing process. By placing the printing process after mold separation and lens removal, the production of all previous processes becomes independent of the pattern and design, allowing for large-scale production as colorless and transparent lenses. This facilitates production scheduling and saves production costs. After mold separation and lens removal, the dry lenses are then printed with different patterns and colors, resulting in unique and distinctive colored contact lens products.

[0004] Dry film is relatively fragile, and the handling mechanisms that directly pick up or grab it in conventional equipment cannot adapt to the batch production of dry film printing operations, thus failing to meet market demands. There is an urgent need to provide a solution. Utility Model Content

[0005] The purpose of this invention is to provide a contact lens dry film feeding device that can automatically feed dry films with high feeding efficiency, improve the overall production efficiency of contact lens dry films, and facilitate batch processing of dry films.

[0006] To achieve the above objectives, this utility model provides the following technical solution;

[0007] A dry contact lens loading device includes a tray transport mechanism for transporting dry lens trays, a vision mechanism for visually positioning the dry lenses, a platform mechanism for transferring dry lenses, and a dry lens transport robotic arm for transporting dry lenses onto a dry lens carrier.

[0008] During loading, the tray transport mechanism moves the dry sheet tray to the platform mechanism, which then moves the dry sheet tray to the vision mechanism. The vision mechanism visually positions the dry sheet to be transferred within the dry sheet tray. The dry sheet transport robot arm then moves the dry sheet to be transferred from the dry sheet tray to the dry sheet carrier.

[0009] Furthermore, the tray transport mechanism includes a tray moving drive device, a tray lifting drive device driven by the actuator of the tray moving drive device, and a tray fixture driven by the actuator of the tray lifting drive device; the tray lifting drive device drives the tray fixture to move up and down, so that the tray fixture can pick up and place the dry film tray; the tray moving drive device drives the tray lifting drive device and the tray fixture to move, thereby transporting the dry film to be printed.

[0010] Furthermore, the stage mechanism includes a turntable drive device and a tray platform driven by the turntable drive device. The tray platform has multiple tray positioning slots. The tray transport mechanism transports the dry film tray to the tray positioning slots. The turntable drive device drives the tray platform to rotate, moving the dry film tray placed in the tray positioning slots into the vision mechanism. After the dry film to be transferred on the tray platform is transported, the turntable drive device drives the tray platform to rotate, moving the empty dry film tray to the tray transport mechanism, which then removes the empty dry film tray.

[0011] Furthermore, a supplementary lighting panel is also provided below the tray platform.

[0012] Furthermore, the vision mechanism includes a recognition lens for identifying dry film and a recognition column for mounting the recognition lens; the recognition column is mounted on one end of the platform mechanism near the dry film transport robot arm; the recognition lens is slidably mounted on the recognition column using a sliding track module.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This dry contact lens loading device integrates a tray transport mechanism, a vision mechanism, a platform mechanism, and a dry lens transport robotic arm to perform coordinated operations. It enables the transport, transfer, visual positioning, and gripping of dry lenses, allowing for batch loading of dry lenses. Simultaneously, it can remove empty dry lens trays, facilitating rapid transfer of dry lenses and trays. This improves production efficiency and facilitates efficient, rapid, and batch dry lens processing. Attached Figure Description

During loading, the tray transport mechanism 210 transports the dry lens tray 110 onto the platform mechanism 230, the platform mechanism 230 moves the dry lens tray 110 to the vision mechanism 220, the vision mechanism 220 visually positions the dry lens to be transferred within the dry lens tray 110, and the dry lens transport robotic arm 240 transports the dry lens from the dry lens tray 110 onto the dry lens carrier 800.

[0019] In practical use, the tray handling mechanism 210 is used to handle and load the dry sheet tray 110, improving the dry sheet loading efficiency; the vision mechanism 220 performs visual positioning of the dry sheets to be printed in the dry sheet tray 110, providing visual guidance to the dry sheet handling robot arm 240, so as to assist the dry sheet handling robot arm 240 in accurate positioning and gripping, improving the accuracy of the dry sheet loading and handling process and reducing waste sheets; the empty dry sheet tray 110 can be moved by the platform mechanism 230 to the tray handling mechanism 210, waiting for the tray handling mechanism 210 to remove the empty dry sheet tray 110 and move the loaded dry sheet tray 110 back into the platform mechanism 230, improving the dry sheet loading efficiency, so as to expand and adapt to multiple types of automated production lines.

[0020] This dry contact lens loading device coordinates the actions of the tray transport mechanism 210, the vision mechanism 220, the platform mechanism 230, and the dry lens transport robotic arm 240 to achieve dry lens transport, transfer, visual positioning, and gripping. It can batch load dry lenses and remove empty dry lens trays 110, enabling rapid transfer of dry lenses and dry lens trays 110, thereby improving production efficiency and facilitating efficient, fast, and batch dry lens processing operations, such as dry lens printing.

[0021] In this embodiment, the tray transport mechanism 210 includes a tray moving drive device 211, a tray lifting drive device 212 driven by the actuator of the tray moving drive device 211, and a tray fixture 213 driven by the actuator of the tray lifting drive device 212. During operation, the tray lifting drive device 212 drives the tray fixture 213 to move up and down, so that the tray fixture 213 can pick up and place the dry film tray 110. The tray moving drive device 211 drives the tray lifting drive device 212 and the tray fixture 213 to move, thereby transporting the dry film to be printed.

[0022] Specifically, the tray moving drive device 211 can be a linear motor, the tray lifting drive device 212 can be a lifting cylinder, and the tray tooling 213 can be a gripper or suction cup or other tooling that can realize the gripping and placement of the tray.

[0023] In this embodiment, the carrier mechanism 230 includes a turntable drive device 231 and a carrier plate 232 driven and connected to the actuator of the turntable drive device 231. The carrier plate 232 is provided with a plurality of carrier plate positioning slots 233. During operation, the carrier plate transport mechanism 210 transports the dry film carrier plate 110 to the carrier plate positioning slot 233. The turntable drive device 231 drives the carrier plate 232 to rotate, which drives the dry film carrier plate 110 placed in the carrier plate positioning slot 233 to enter the vision mechanism 220. After the dry film to be transferred on the carrier plate 232 is transported, the turntable drive device 231 drives the carrier plate 232 to move, and moves the empty dry film carrier plate 110 to the carrier plate transport mechanism 210 for removal.

[0024] Specifically, the turntable drive device 231 is a rotary motor. This platform mechanism 230 has a compact structure. The turntable drive device 231 drives the tray platform 232 to rotate, so that it rotates between the tray transport mechanism 210 and the dry sheet transport robot arm 240 to feed dry sheets. This facilitates the loading of dry sheet trays 110 with dry sheets and the removal of empty dry sheet trays 110, thereby improving production efficiency.

[0025] In this embodiment, a supplementary light plate 250 is also provided below the tray platform 232; specifically, the light from the supplementary light plate 250 passes through the tray positioning groove 233 to provide supplementary lighting to the bottom of the dry film tray 110, and assists the vision mechanism 220 in visually recognizing the dry film.

[0026] In this embodiment, the vision mechanism 220 includes an identification lens 223 for identifying dry film and an identification column 221 for mounting the identification lens 223; the identification column 221 is mounted on one end of the platform mechanism 230 near the dry film transport robot arm 240; the identification lens 223 is slidably mounted on the identification column 221 using a sliding track module 222.

[0027] In practical applications, the recognition lens 223 acquires images of the dry film in the dry film tray 110, accurately locates the position of the dry film through recognition points, and transmits the positioning to the dry film handling robot arm 240, providing precision calibration and assistance for the handling work of the dry film handling robot arm 240; improving handling efficiency and accuracy, so as to avoid damaging the fragile dry film and reduce the loss of dry film.
