Description

Technical Field

[0001] This utility model relates to the field of contact lens manufacturing technology, and more specifically, to a fully automated contact lens dyeing and printing equipment. Background Technology

[0002] Contact lenses, also known as corneal contact lenses, are optical devices worn directly on the surface of the cornea. They are primarily used to correct refractive errors (myopia, hyperopia, astigmatism) and can also be used to treat ocular surface diseases or for cosmetic purposes. During the production of contact lenses, some lenses require a dyeing process on the surface to meet market demand.

[0003] The printing and dyeing equipment in related technologies all use a single printing and dyeing head to perform the printing and dyeing process on a single contact lens, and the loading and unloading are done manually, resulting in low production efficiency. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 This application provides a fully automated contact lens printing and dyeing device, including a tray 10 for holding a plurality of contact lenses, and a support platform 20 having a plurality of rectangularly distributed slots 21 for mounting the trays 10. A printing and dyeing mechanism 30 includes a plurality of rectangularly arranged transfer heads 31 positioned above the support platform 20 for simultaneously printing and dyeing a plurality of contact lenses. A clamping mechanism 40 is positioned on one side of the printing and dyeing mechanism 30 for loading and unloading the trays 10 onto the support platform 20. A moving mechanism 50 is positioned above the support platform 20, and its output end is connected to the clamping mechanism 40 and the printing and dyeing mechanisms 30 for moving the printing and dyeing mechanisms 30 and the clamping mechanism 40. A conveying mechanism 60 is symmetrically arranged on both sides of the support platform 20 for conveying the contact lenses.

[0018] Understandably, the tray 10 is a support component that simultaneously holds multiple contact lenses to be processed. For example, it can be multiple independently set up holding platforms for contact lenses, or multiple integrated holding platforms, etc., but is not limited to these. The support platform 20 is a component that holds multiple trays 10 at intervals. For example, it can be a circular platform, or a square platform, etc., but is not limited to these. The tray 21 is a component that positions the tray 10. For example, it can be a groove, or multiple positioning plates, etc., but is not limited to these. The printing mechanism 30 is a component that prints patterns onto the surface or interior of the contact lenses. For example, it can be a pad printing mechanism 30, or a sandwich printing mechanism 30, etc., but is not limited to these. The clamping mechanism 40 is a component that clamps the tray 10 and then moves the contact lenses within the tray 10. For example, it can be a pneumatic suction clamping device with a sliding mechanism, or a combination of a magnetic suction clamping device with a sliding mechanism, etc., but is not limited to these. The moving mechanism 50 is a component that simultaneously drives the clamping mechanism 40 and the printing mechanism 30 to move back and forth. It can be, for example, a screw and nut mechanism or an electric push rod mechanism, but is not limited to these. The moving mechanism 50 is mounted above the support platform 20 via a fixing component. For example, the moving mechanism 50 can have its own frame, fixed to the ground around the support platform 20 by threaded screws, or it can be mounted on a support frame on a fixed wall, with the moving mechanism 40 fixedly connected to the support frame, etc., but is not limited to these installation methods. The pad printing head 31 is a component that prints the pattern onto the surface of the contact lens. For example, it can be a silicone-based pad printing head 31 or a fluorosilicone pad printing head 31, etc., but is not limited to these. The conveying mechanism 60 is a component that transports the contact lenses on the tray 10 to and from the clamping mechanism 40. For example, it can be a continuous conveyor belt conveying mechanism 60, or two conveying mechanisms 60 can be set up on both sides of the support platform 20, etc., but is not limited to these installation methods.

[0019] As can be seen from the above, the equipment is rectangularly arranged with multiple printing heads 31 that simultaneously print multiple contact lens surfaces. It is connected to the printing and dyeing mechanism 30 and the clamping mechanism 40 through the same moving mechanism 50. The moving mechanism 50 drives the printing and dyeing mechanism 30 and the clamping mechanism 40 to move synchronously. When the printing and dyeing mechanism 30 prints the contact lenses, the clamping mechanism 40 performs unloading and loading operations on the material tray 10 of the printed contact lenses. By printing at multiple stations and saving contact lens material changing time, the processing efficiency is improved.

[0020] As is known, in some embodiments, please refer to Figure 4 The material trays 10 are arranged in multiple rows and columns of rectangles on the support platform 20. Several holders 11 for holding contact lenses are spaced apart on the material trays 10. Several printing and dyeing mechanisms 30 are provided, each corresponding to a single row of material trays 10. Clamping mechanisms 40 and printing and dyeing mechanisms 30 are also provided in a corresponding manner.

[0021] Understandably, the placement component 11 is a support component used to place contact lenses and is correspondingly arranged with the pad printing head 31. For example, it can be a flexible placement component 11 or a rigid placement component 11, but it is not limited to these. The number and arrangement of the placement components 11 are the same as those of the pad printing head 31. The trays 10 are arranged in multiple rows on the support table 20, and each row has multiple trays 10. The number of single-row or single-column printing and dyeing mechanisms 30 is equal to the number of single-row or single-column trays 10. For example, the number of single-row trays 10 can be equal to the number of single-row printing and dyeing mechanisms 30, or the number of single-column trays 10 can be equal to the number of single-column printing and dyeing mechanisms 30, but it is not limited to these. Since one clamping mechanism 40 clamps one tray 10, the number of clamping mechanisms 40 and printing and dyeing mechanisms 30 is equal.

[0022] With this setup, through the corresponding arrangement of multiple material trays 10, multiple printing and dyeing mechanisms 30, and multiple clamping mechanisms 40, more contact lenses can be operated by the printing and dyeing mechanisms 30 and the clamping mechanisms 40, thereby improving production efficiency.

[0023] As is known, in some embodiments, please refer to Figure 1 and Figure 3 The printing and dyeing mechanism 30 also includes a lifting component 32 connected to the output end of the pad printing head 31, which is used to drive the pad printing head 31 to move up and down. The pad printing head 31 is set one-to-one with the placement component 11.

[0024] Understandably, the lifting component 32 is a component that pushes the transfer head 31 to contact the surface of the contact lens. For example, it can be a pneumatic telescopic mechanism or a hydraulic telescopic mechanism, but it is not limited to these.

[0025] As is known, in some embodiments, please refer to Figure 2 and Figure 3 The clamping mechanism 40 includes: a clamping plate 41, disposed above the material tray 10, for clamping the material tray 10; a telescopic member 42, the output end of which is connected to the clamping plate 41, for driving the clamping plate 41 to descend and clamp the material tray 10; and a sliding drive member 43, the output end of which is connected to the telescopic member 42, for driving the contact lens to move left and right.

[0026] Understandably, the telescopic component 42 drives the clamping plate 41 to descend. The clamping plate 41 is fixed at the output end of the telescopic component 42 to clamp the material tray 10. The sliding drive component 43 drives the contact lens to move left and right. This is how the contact lens is grasped and moved. For example, the combination can be that the pneumatic clamping plate 41 is set at the output end of the electric push rod, and the electric push rod is set on the nut screw mechanism. It can also be a combination of suction clamping plate 41 plus pneumatic push rod plus nut screw mechanism, etc., but it is not limited to these.

[0027] This setup, through the combined use of multiple mechanisms, enables complex automated loading and unloading operations, saving manpower.

[0028] As is known, in some embodiments, please refer to Figure 4 The conveying mechanism 60 includes: a feeding component 61, disposed on one side of the support platform 20, for feeding the tray 10 to the clamping mechanism 40; and a discharging component 62, disposed on the other side of the support platform 20 opposite to the feeding component 61, for receiving the tray 10 fed by the clamping mechanism 40 and discharging it. The feeding component 61 is provided with baffles 611 along its conveying direction, dividing it into several conveying sections corresponding to each row of trays 21.

[0029] Understandably, the feeder 61 is a component that transports the trays 10 to the trays 21 on the support platform 20. Since the clamping mechanism 40 moves linearly left and right when clamping, the position of the trays 10 and the position of each row of trays 21 correspond during feeding. Therefore, the feeder 61 needs to be divided into multiple conveying sections. The number of conveying sections is equal to the number of rows of trays 21, and one conveying section corresponds to one row of trays 21. For example, there can be one feeder 61, and after multiple baffles 611 are installed on the conveying surface of the feeder 61, the conveying surface of the feeder 61 is divided into multiple conveying sections by the baffles 611. One conveying section corresponds to conveying a whole row of trays 10. Alternatively, multiple independent feeders 61 can be used in combination, and multiple feeders 61 can be separated by baffles 611, etc., but it is not limited to these.

[0030] With this configuration, when the conveying section on the feeder 61 conveys the corresponding single-row tray 21, the movement direction of the tray 10 is restricted by the baffle 611 to prevent the tray 10 from losing its position due to the vibration of the conveying mechanism 60, so that the tray 10 can be transported stably.

[0031] As can be seen from the above, the multi-row material tray 10 is placed on the feeding part, and the printing and dyeing mechanism 30 rises after completing one printing and dyeing cycle. The moving mechanism 50 drives the printing and dyeing mechanism 30 to move to the next row of contact lenses that need to be printed and dyed. At the same time, the moving mechanism 50 also drives the clamping mechanism 40 to move above the contact lenses that have been printed and dyed. The printing and dyeing mechanism 30 descends to print new contact lenses, and the clamping mechanism 40 clamps the contact lenses that have been printed and dyed and moves them to the unloading part 62 to convey the contact lenses of the printing and dyeing process out. The above steps are repeated.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
