Description

Technical Field

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

[0002] In the production process of dry contact lenses, liquid is injected into the lower mold and then molded together with the upper mold. After the molding and curing, the upper and lower molds need to be opened to separate the lens from the mold and remove the complete contact lens (dry lens).

[0003] After the dry sheets are demolded and separated, they need to be collected and coiled. This is usually done manually or semi-automatically. This method is labor-intensive and has low production efficiency, which cannot meet market demand. Therefore, there is an urgent need to provide a solution. Utility Model Content

[0004] The purpose of this invention is to provide a device for automatically and quickly loading dry contact lenses into trays after molding.

[0005] To achieve the above objectives, this utility model provides the following technical solution;

[0006] A dry contact lens flipping and placing device includes a flipping assembly, a tray rack for placing a receiving tray, a dry lens flipping drive for driving the flipping assembly to flip, and a tooling drive mechanism for driving the dry lens flipping drive to move.

[0007] When the dry sheets are arranged on the tray, multiple dry sheets are placed at the flipping assembly, which fixes the dry sheets in place; the dry sheet flipping drive device drives the flipping assembly to flip and change the direction of the dry sheets fixed on the flipping assembly; the tooling drive mechanism drives the dry sheet flipping drive to move the flipping assembly to the tray rack, and the flipping assembly places the dry sheets into the receiving tray.

[0008] Furthermore, the flipping assembly includes a tooling frame and multiple pickup components mounted on the tooling frame; the pickup components secure the transferred dry film.

[0009] Furthermore, the tooling drive mechanism includes a tooling displacement drive device and a tooling lifting drive device that is driven and connected to the execution end of the tooling displacement drive device; the tooling displacement drive device drives the tooling lifting drive device to move the flipping assembly to the receiving tray along with the dry sheet flipping drive device.

[0010] Furthermore, an electrostatic dust removal unit is also provided at the flipping assembly; when the tooling drive mechanism drives the dry sheet flipping drive device to carry the flipping assembly through the electrostatic dust removal unit, the electrostatic dust removal unit performs dust removal on the dry sheet.

[0011] Furthermore, the tray rack is also provided with a tray transfer drive mechanism, and a tray transfer fixture is driven and connected to the execution end of the tray transfer drive mechanism.

[0012] During operation, the transfer drive mechanism drives the transfer fixture to move the receiving tray containing the dry film out of the tray rack from the tray rack.

[0013] Furthermore, the pallet transfer drive mechanism includes a pallet transfer displacement drive device, a pallet transfer lifting drive device that is driven and connected to the execution end of the pallet transfer displacement drive device, and a tooling steering drive device that is driven and connected to the execution end of the pallet transfer lifting drive device.

[0014] The pallet transfer drive device drives the pallet lifting drive and the tooling steering drive to move, so that the pallet transfer tooling picks up the receiving tray containing dry sheets at the pallet rack.

[0015] Furthermore, the actuator of the tooling steering drive device is connected to two pallet transfer fixtures; when one pallet transfer fixture picks up the receiving tray containing dry sheets at the pallet rack, the other pallet transfer fixture picks up the empty receiving tray at the receiving tray.

[0016] When the tooling steering drive device rotates, it causes the transfer tooling that picks up the empty receiving tray to rotate to the tray rack; at the same time, it causes the transfer tooling that picks up the receiving tray containing dry sheets to move to the receiving tray position.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In practical use, the flipping assembly is used to fix dry sheets with a specific incoming orientation; the tray rack is used to temporarily place empty receiving trays; the dry sheet flipping drive device drives the flipping assembly to flip and change orientation, so that the fixed dry sheets change their fixed orientation, which facilitates subsequent tray placement.

[0019] This dry contact lens flipping and placement device uses a flipping assembly to load and fix multiple dry lenses, increasing the number of lenses that can be placed in a single batch. The dry lens flipping drive enables secondary orientation changes of the incoming dry lenses, adapting to various placement requirements. The tooling drive mechanism drives the dry lens flipping drive device and the flipping assembly to perform rapid and stable reciprocating motion, enabling automated and rapid batch placement of dry contact lenses into trays, thus improving the overall production efficiency of contact lenses.
