Optical encoder assembly

Abstract

The invention discloses an optical encoder assembly. The optical encoder assembly is composed of an encoder mechanical unit and a photoelectric unit; the encoder mechanical unit comprises a base and acover body; the photoelectric unit is a circuit board pasted with an optical module; the optical module comprises a light-emitting element and a photosensitive element; the encoder mechanical unit iscombined with the photoelectric unit circuit board through the base; the encoder mechanical unit is matched with the photoelectric unit to achieve generation of photoelectric signals. According to the encoder, an optical path module with an innovative structure is adopted; a light blocking turntable is matched with the optical path module to realize the change of an optical path; an optical pathswitch module is ingeniously simplified by the structure, the structure is light and thin, the layout is more reasonable, and the cost is saved; in addition, a concave-convex surface is arranged on the light blocking turntable and can be matched with an elastic piece to provide sectioned hand feeling for a user. The optical encoder assembly is compact in structure, convenient to use and suitable for batch production. According to the optical encoder assembly, space can be fully utilized.

Description

technical field [0001] The invention relates to an encoding signal output device, in particular to an optical encoder. Background technique [0002] The rotary coding switch is a common row of switches on the motherboard used as a jumper to adjust the frequency. It is also called a coding switch and a dial switch, and outputs binary BCD codes. [0003] Existing optical encoders generally adopt a grating structure, namely: a light-emitting diode, two receiving tubes, and a roller grating between them. When the rolling wheel rolls, the grating continuously blocks and transmits light, so that the receiving tube obtains pulse signals, thereby realizing perception. The rolling effect of the roller requires some mechanical structure to achieve a smooth feel when turning. However, due to the addition of a mechanical structure, the thickness of the product and its use will also be affected, and the overall structure will become complicated accordingly. Difficult to use. Contents ...
