Problems solved by technology

[0013] However, in each jig mounting device, identification marks such as invisible marks or printed marks may be double-imaged. In this case, there is a problem that it cannot be determined which of the double-imaged identification marks is used as a reference to determine mounting. point

Embodiment 1

[0090] 1 and 2 show an embodiment of a clamp installation device 1 of the present invention. The jig installation device 1 in this embodiment accurately installs a jig 3 for processing a lens, especially a spectacle lens 2, on the spectacle lens 2 (refer to FIG. 2 ). As shown in FIG. 1 , the jig installation device 1 includes a housing 4 , a liquid crystal display unit 5 , and an operation key unit 6 .

[0091] As shown in FIG. 2 , the jig installation device 1 includes a support device for a spectacle lens 2 disposed inside a casing 2 . In the illustrated embodiment, the supporting device includes: a fixed plate 7 for placing unprocessed spectacle lenses 2; a platform 8 on which the fixed plate 7 is placed; a driving mechanism for driving the platform 8 in X and Y directions 9 ; and a drive mechanism 10 for driving the fixed plate 7 to rotate relative to the platform 8 .

[0092] The spectacle lens 2 includes: a printed mark 20 printed on its surface 2a, an identification m...

example 2

[0266] As shown in FIG. 31 , when the interchangeable frame lens holder 570 is installed on the ring gear 551 , the images shown in FIGS. 50 to 53 are displayed on the liquid crystal display 129 . In FIGS. 50 to 53 , reference numeral 950 denotes an arm image of the lens holding arm 66 , and reference numeral 952 denotes a cutout area. In Fig. 51, reference numeral 951 denotes the lens shape of the interchangeable frame lens holder shown in Figs. 30 and 31 .

[0267] Next, referring to FIG. 54 , the processing of Example 2 for checking the presence or absence of spectacle lenses will be described below.

[0268] (step S11)

[0269] The operation control circuit 100 receives the image signal from the CCD 115, starts the process of judging whether there is a lens shown in FIG.

[0270] That is, the arithmetic control circuit 100 sets the cutout area 952 (processing area) indicated by the square frame in FIG. 50, and proceeds to step S12. The cut-out area 952 is set approximat...

Abstract

A jig mounting device which comprises a detection optical system for detecting the identification mark of a glasses lens and is constructed so as to determine a mounting point based on an identification mark detected by the detection optical system, position the mounting center of the jig used when a glasses lens is processed onto the mounting point, and mount the jig on the surface of the glasses lens, wherein the detection optical system comprises a condensing optical system for condensing a luminous light flux from a light source onto the surface of the glasses lens formed with a concealed mark via a stop, a reflection plate for reflecting the light flux condensed by the condensing optical system and passed through the glasses lens, and an imaging means provided to be positioned almost optically conjugate with the stop so as to be focused on a spatial portion along the optical axis from the surface of the glasses lens.

Description

technical field [0001] The present invention relates to a jig installation device, in particular to a jig installation device which reads an invisible mark drawn on a spectacle lens as a reference mark and can automatically install a jig used for processing spectacle lenses on the spectacle lens . Background technique [0002] Generally speaking, in spectacle lenses such as progressive addition lenses, printed marks or invisible marks are provided as reference marks when a jig for processing spectacle lenses is mounted on the spectacle lenses. [0003] Conventionally, for example, in the following patent documents 1 to 8, there are disclosed jig installation devices which detect identification marks such as invisible marks by using a detection optical system, and based on the identification marks detected by the detection optical system, Determine the mounting point on which the jig used to process the spectacle lens is located, and install the jig on the spectacle lens. ...
