Description

Convenient door opening device for processing spectacle lens

Technical Field

The utility model relates to a lens processing technology field, concretely relates to just, door opener of lens processing.

Background

An uncut spectacle lens is processed into a shape suitable for a spectacle frame, and the cut lens is fitted into the spectacle frame to prepare spectacles. The lens manufacturer prepares and provides uncut disc lenses based on prescription data (diopter, cylinder diopter, distance between right and left eyes, etc.) for the eyes of the person who will wear the glasses, shape data of the eyeglass frame selected by the person wearing the glasses, and contour information.

The processing of the spectacle lens is completed by a convenient door opening device for processing the spectacle lens, before processing, the processed spectacle lens needs to be clamped by a clamping mechanism which is a self-rotating mechanism, in the prior art, the clamping mechanism consists of a left clamping part and a right clamping part, if the left clamping part is an active driving part, the right clamping part is connected with the left clamping part by a synchronous belt, when the left clamping part works, the power is transmitted to the right clamping part by the synchronous belt, so that the left clamping part and the right clamping part can synchronously rotate, however, because the material of the synchronous belt is usually rubber, after a period of use, the synchronous belt can become loose, the rotating speeds of the left clamping part and the right clamping part can not be synchronous, and the clamping parts for clamping two ends of the spectacle lens form relative motion, causing wear to the ophthalmic lens.

In addition, when the spectacle lens is processed, at least two procedures of rough cutting and fine cutting are usually carried out, for some spectacle lenses, the processed edge also needs to be processed by fine grinding or grooving, the cutter device in the current processing equipment comprises a cutter disc and a central driver, wherein a plurality of cutter drivers are installed on the cutter disc, the output end of each cutter driver is connected with one cutter, for example, when the rough cutting is needed, the central driver drives the cutter disc to rotate, so that the rough cutting cutter reaches the lens processing position, and when the fine cutting is needed after the rough cutting is finished, the central driver drives the cutter disc to rotate, so that the fine cutting cutter reaches the lens processing position, and therefore, the corresponding cutter is selected according to the required processing precision or cutting mode. However, since a plurality of machining tools are disposed on the same circumference of the same cutter head, the cutter head becomes bulky, and the size of the apparatus increases. And each cutter needs to be provided with a driving motor, so that the equipment cost is high.

In addition, since a large amount of plastic splashes are generated when the lens is cut in the course of processing the spectacle lens, the processing is performed in a closed environment, and a transparent portion is generally provided on the closed portion in order to observe the processing course or the processing state. The transparent part and the closed part on the existing equipment are integrated, when the lens to be processed is replaced, the closed part needs to be integrally opened, and the next processed lens can be replaced.

The utility model also comprises a convenient door opening device I which is movably connected with the frame G, the convenient door opening device I comprises a main door 60, a handle 61, a gas spring component, a transparent auxiliary door 62 and a third linear driving mechanism, one end of the main door 60 is hinged with the frame G, and the handle 61 is fixed with the main door 60; the gas spring assembly is connected with the frame G and the main door 60; the main door 60 is provided with a window, and the auxiliary door 62 is matched with the window on the main door 60; the third linear drive mechanism cooperates with the sub-door 62 to drive the sub-door 62 to open or close the window.

In this embodiment, if the easy-open device I needs to be completely opened, the main door 60 is opened, and since the main door 60 is supported by the gas spring assembly, the main door 60 is maintained at the position of the main door 60 by the gas spring assembly after being opened, so that the opening of the main door 60 can be selected according to the requirement. When the processed spectacle lens A needs to be replaced, the problem can be solved by opening the auxiliary door 62, the auxiliary door 62 is driven to move by the third linear driving mechanism, the window on the main door 60 is in an open state, the processed spectacle lens A is taken out through the window, and the spectacle lens to be processed is replaced. Because the area of the window is not large and the opening degree of the auxiliary door 62 to the window can be selected, even if the window is opened immediately after the spectacle lens is cut, only little dust floats to the outside of the equipment, thereby greatly reducing the pollution to the environment.

The gas spring assembly comprises a first support 63, a gas spring 64, a second support 65 and a third linear driver 66, wherein the first support 63 is fixed with the rack G; one end of the gas spring 64 is hinged with the first support 63; the second support 65 is hinged to the other end of the gas spring 64, and the second support 65 is fixed to the main door 60.
