Embodiment Construction

[0021] Such as Figure 1-5 As shown, the present invention provides an absolute encoder, which includes: a housing 10 , a main shaft 20 disposed inside the housing 10 , a main body 30 sleeved outside the main shaft 20 , a code disc seat 40 , and a metal code disc 50 . A bearing 22 is provided between the main shaft 20 and the main body 30, and a slit assembly 24 is provided outside the main shaft 20, and the slit assembly 24 includes a metal slit sheet 242, a luminous tube printed board 244, and a connecting metal slit The connecting plate 246 of the slit 242 and the luminous tube printed board 244 . The main body 30 is made of plastic-steel insulating material (PPS), and the shell 10 and the connecting plate 246 are made of acrylonitrile-styrene-butadiene copolymer (ABS) plus glass fiber material, which is not only easy to assemble, The accuracy is high, and leakage phenomenon can be prevented, and the use is relatively safe.

Abstract

The invention discloses an absolute value coder, which comprises a casing, a spindle arranged in the casing, a main body sleeved on the outer side of the spindle, a code disc base and a metal code disc. A bearing is arranged between the spindle and the main body, a slit assembly is further arranged on the outer side of the spindle, the slit assembly comprises a metal slit sheet, a light-emitting tube printed board and a connecting board for connecting the metal slit sheet and the light-emitting tube printed board, the main body is made of glass-reinforced plastic insulation materials, and the casing and the connecting board are both made of acrylonitrile butadiene styrene (ABS) and glass fiber materials. The absolute value coder is convenient to assemble, high in accuracy, capable of avoiding electric leakage and safe to use.

Description

technical field [0001] The present invention relates to an encoder, in particular to an absolute value encoder. Background technique [0002] An encoder (encoder) is a device that compiles and converts signals (such as bit streams) or data into signal forms that can be used for communication, transmission and storage. It is an electronic component that outputs control signals. It converts several binary digits 0 and 1. Arrange according to certain rules to form different codes. [0003] The absolute value encoder is a type of encoder. Because it is a multi-code channel reading, the value is coded from the 0th power of 2 to the n-1th power of 2, so its output is different from the incremental pulse. output. From the perspective of physical device classification, it can be divided into parallel output, serial synchronous output, serial asynchronous bus output, and converted analog output. [0004] However, the absolute value encoders commonly used in the market are mainly m...
