Description

Technical Field

[0001] The utility model relates to the technical field of encoders, in particular to an absolute encoder with dense and narrow code paths. Background Art

[0002] A dense and narrow code channel absolute encoder is a sensor used to accurately measure position. It achieves high-precision position detection by setting dense and narrow code channels on the encoder's code disk. An absolute encoder means that the position information it outputs is absolute, that is, the encoder can output a unique digital code corresponding to the position of the shaft at any time, without the need to determine the current position by counting or referring to other positions.

[0003] An encoder is a rotary sensor that converts rotational displacement into a series of digital pulse signals. It is mounted on one end of the motor shaft and can feed the motor's rotation signal back to the controller. The controller then controls the rotation of the motor shaft based on the feedback signal. However, existing encoders lack protective measures during operation, which can easily cause the housing to corrode, rust, or collide, resulting in poor safety. Therefore, a protective device for the encoder is needed to address this issue.

[0004] The existing patent (publication number: CN210154604U) provides a protective device for an encoder, comprising an upper anti-corrosion cover and a lower anti-corrosion cover, the lower end of the upper anti-corrosion cover is fitted with the lower anti-corrosion cover, the upper anti-corrosion cover and the lower anti-corrosion cover are both fitted with the front end of the baffle, the upper anti-corrosion cover and the lower anti-corrosion cover are both fitted with the rear end of the fixed plate, the fixed plate is fixedly connected to the front inner wall of the protective shell for collision prevention, the inside of the protective shell is symmetrically rotated to connect two two-way adjusting screws, the annular outer side of the two-way adjusting screw is threadedly connected to two nuts, the two nuts are respectively fixedly connected to the upper end of the upper anti-corrosion cover side straight plate and the lower end of the lower anti-corrosion cover side straight plate, and at least two heat sinks are equidistantly arranged on the outer side of the middle arc plate of the upper anti-corrosion cover and the outer side of the middle arc plate of the lower anti-corrosion cover. This design forms a sealed space for installing the encoder through the baffle, fixed plate, upper anti-corrosion cover and lower anti-corrosion cover to prevent humid air from entering, and has good safety.

[0005] In response to the above problems, existing patents have provided solutions. However, when using existing absolute encoders, they do not have an external wiring harness protection structure, which causes the connecting harness to be excessively bent during use, resulting in fatigue fracture of the metal wires inside the connecting harness, affecting the stability and reliability of signal transmission. The existing patents cannot solve this problem, so it is not conducive to user use.

[0006] Therefore, a dense and narrow code channel absolute encoder is proposed. Utility Model Content
