Description
Technical Field
The present invention relates to encoders, and particularly to a dual-layer encoder.
Background
An encoder (encoder) is a device that compiles, converts, and formats signals (e.g., bitstreams) or data into a form of signals that can be communicated, transmitted, and stored. Encoders convert angular or linear displacements, called codewheels, into electrical signals, called coderulers. The encoder can be divided into a contact type and a non-contact type according to a reading mode; encoders can be classified into an incremental type and an absolute type according to their operation principles. The incremental encoder converts displacement into periodic electrical signals, and then converts the electrical signals into counting pulses, and the number of the pulses is used for expressing the magnitude of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so that its representation is only dependent on the start and end positions of the measurement, and not on the intermediate course of the measurement.
The double-layer encoder is a combined electronic element formed by overlapping and combining two encoders. However, in the existing double-layer encoder, each encoder unit is provided with one control shaft, the two control shafts are usually arranged in an inner and outer shaft structure, and each control shaft independently controls the corresponding encoder unit. For example, the present chinese utility model with publication number CNCN210893176U discloses "an electronic product with expandable double-layer encoder", including outer axle rotation coding subassembly, interior axle rotation coding subassembly, metal dome and keying circuit, outer axle rotation coding subassembly is including first encapsulation shell, second encapsulation shell, outer axle, first division board, first photoelectric transmission circuit, first grating subassembly and photoelectric receiving circuit, first encapsulation shell, second encapsulation shell, outer axle, first division board, first photoelectric transmission circuit, first grating subassembly and photoelectric receiving circuit arrange in proper order, interior axle rotation coding subassembly is including interior axle, second grating subassembly, second photoelectric transmission circuit, second division board, interior axle positioning disk, third encapsulation shell, third division board, silica gel pad and fourth division board.
