Description of the Invention: [Technical Field] The present invention provides a device for preventing interference of light interference of an operation panel of an automatic machine, and particularly refers to a plurality of buttons on an operation panel, the operation state light and the non-operation The state lights do not interfere with each other. [Prior Art] According to the prior art, a typical device, such as the patented construction device of the operation panel for industrial control devices, is disclosed in the Taiwan New Type Bulletin No. 4 9 6 6 5 4 And the application case is the invention patent of "Modularized Device for Operation Panel of Automated Machinery" No. 9 2 1 2 8 8 6 0. This prior art has the following shortcomings under the long-term implementation: (1) · When working When the environment is dark or black, the transparent multi-function button on the operation panel of the working machine (such as CNC lathe) will display a weak backlight, so as to highlight the position of the button, but the light-transmitting point area of the side angle of the button surface Is a light indicating the state of the operation function (hereinafter referred to as operation light). Due to the two light-emitting diodes on the board, the backlight (weak light) is emitted at any time, and the other can emit the operating light (glare) in time. There is no barrier under the button, so the backlight and the operating light It is very easy to produce two kinds of light interference and the surface of the button that is unclear is displayed. Therefore, in a weak working environment, it is very easy for the user to mistake the backlight for the operation light. (2) The light-transmitting convex mirror surface of the operation light is lower than the surface of the button, especially the hollow system is a tapered hole, so the effect of collecting light is poor. SUMMARY OF THE INVENTION 1247569 The reason is that the main purpose of the present invention is to provide a preventive device for the operation panel, and to exert (4) surface-exposed and known light, one of which does not relate to confusion. The re-purpose of the present month is to provide a control device for the optical interference of the operating panel of the automated machine, and to perform the operation of the light and the light is better. The present invention provides an operating panel for an automated machine. The light interference preventing device comprises: an operation panel 1 ,, at least one or more piercing workers 2, a plurality of buttons 50, each of which has a front convex surface 5 4 piercing the perforation 1 2 and rear a flange portion 5 2 having a large area; one side surface 4 4 of the waterproof rubber pad 40 is attached to the flange portion 5 2; the frame 20 is attached to the back surface of the waterproof rubber pad 40; the circuit board 3 0 is abutted on the rear side of the frame 20; the circuit board 30, the frame 20, the waterproof pad 40 and the button 50 are combined and fixed on the back surface of the operation panel 10, and the features are provided on the frame 20 At least one or more of the backlight through holes 2 2 , the side of the backlight through hole 2 2 is provided with a shielding frame 2 2 1 , the shielding frame 2 2 1 has an operation light through hole 2 2 2; the inside of the button 50 is provided with a tubular shape Hollow body 55', a convex body 5 3 is formed above the hollow body 5 5 , and the rear end is an inlet end 5 5 1 ; 30, respectively, A light-emitting element 3 4 and B light-emitting element 1247569 piece 3 5 are arranged, wherein A light-emitting element 34 is located in the operation light-transmitting hole 2 2 2 'B light-emitting element 35 corresponds to the backlight through-hole 2 2 By blocking the frame 2 2 1 , the a and b light-emitting elements 3 4 and 3 5 can be prevented from being confused with each other by the interference light. As shown in FIG. 3 and FIG. 4, wherein the surface of the convex mirror body 53 has a curved surface, and protrudes and faces the surface 5 1 of the button 5 , the convex mirror body 53 can be a transparent magnifying glass; the hollow body 5 5 is The hollow tube of equal diameter has an inner wall surface with atomized opaque spots 552. The waterproof rubber pad 40 is a transparent or translucent soft rubber pad having a plurality of concave portions 45 to form a preferred light transmitting region, and the concave portion 45 corresponds to the inlet end of the hollow body 55. The light emitted from the element 34 passes through the concave portion 45 and is swept by the hollow body 55, and is then amplified and emitted by the convex mirror body 53. The button 50 is a transparent acrylic product, and the weak light emitted by the B light-emitting element 35 can pass through the surface 5 of the button 5 to form a weak light (backlight). A plastic inner frame 915 having a mixture of color phosphors can be inserted into the operation light through hole 2 2 2 . The side wall surface of the inner frame 9.5 has a flexible inclined convex plate 9 5 1 ' at the bottom of which a groove 9 5 2 is provided. [Embodiment] (1)· As shown in Fig. 1, the case is screwed to the panel by a button 5 〇, a soft waterproof pad 4 〇, a plastic molded frame 2 电路, and a circuit board 30 by a fixed block 6 0 I247569. The back side of 10 is used to form an operation panel for industrial automation machinery. As shown in FIG. 2 and FIG. 3, the shadow frame 2 2 1 is an opaque frame, and the operation light through hole 2 2 2 inside the shadow frame 2 2 1 can be sleeved into an inner frame 9.5. 9 5 can be selected as a blue or yellow or red ... and other colors of the phosphor material mixed with a plastic inner frame 9 5, Α light-emitting elements 3 4 (ie, LED), the white light source emitted, the emission excitation On the groove 9 5 2, the color phosphor in the material of the entire inner frame 9.5 is excited to generate a sensitizing effect 'so that the color light formed outside the inner frame 9.5 is the same as or similar to the plastic inner frame 9.5. The light of the color. The color light is emitted into the hollow body 5 5 from the light-transmissive recess 4 5 and the inlet end 5 5 1 , and the hollow body 5 5 is a hollow tubular tube of equal diameter, and the inner wall is an opaque region of the mist spot 5 5 2 The convex mirror body 53 has a light amplifying effect, and the inner wall thereof is a transparent region. Therefore, the hollow body 55 has the effect of light collecting and collecting light, and the operating function light having color appearance is amplified by the convex mirror body 53. Highlighted. The color-operated function light does not penetrate through the backlight through-hole 2 2 due to the blocking of the shadow frame 2 2 1 . (2) When the B light-emitting element 35 emits a weak light, it passes through the transparent button 5 〇 to emit a weak light (ie, a backlight). At this time, a significant effect is achieved, that is, the blocking of the shielding frame 2 2 1 causes the operating light and the backlight emitted by the A, B illuminating elements 34, 35 to not interfere with each other, so that the effect is to be dim or dark. In the working environment, the backlight that always emits light will never interfere with the light function of the operation function, so that the backlight will never pass through the convex mirror body 53, or the operation light will be transmitted from the surface 5i. 1247569 [Simple description of the drawings] The first figure is an exploded perspective view of the operation panel of the present invention.
