Problems solved by technology

[0004] In the prior art, such as patent 201620077231.7, in the servo reducer, if two encoders are used up and down to measure the rotation angles of the motor and the reducer respectively, this arrangement will lead to a large number of joint parts and increase the production cost, and It leads to large joint volume and weight, which reduces the load capacity of the joint belt

Embodiment Construction

[0023] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0024] Such as Figure 1-5 As shown, the present invention provides a double code disc encoder 1, including a first code disc 10 for measuring the rotation angle of the reducer, a second code disc 11 for measuring the motor rotation angle, and a first reading head for reading And the second reading head, used to fix the circuit board 12 of the first reading head and the second reading head, wherein the first code wheel 10 and the second code wheel 11 are coaxial and nested on the same plane. The coaxial and horizontal nesting of the first code wheel 10 and the second code wheel 11 can reduce the number of parts and reduce the volume of the corresponding servo joint compared with the prior art where two encoders are arranged up and down.

[0025] Specifically, the first code disc 10 is used to measure the rotation angle of the reducer in t...

Abstract

The invention relates to the technical field of encoders, in particular to a dual-coded-disc encoder and a servo joint using the dual-coded-disc encoder. The dual-coded-disc encoder comprises a firstcoded disc, a second coded disc, a first reading head, a second reading head and a circuit board, wherein the first coded disc is used for measuring a reduction gear corner, the second coded disc is used for measuring a motor corner, the first reading head and the second reading head are used for reading, and the circuit board is used for fixing the first reading head and the second reading head;and the first coded disc and the second coded disc are coaxially embedded in a same plane. The dual-coded-disc encoder has the advantages that the first reading head and second reading head used for measuring the reduction gear corner and the motor corner are coaxially embedded in the same plane, and compared with the arrangement of the two encoders in the prior art, the size of the servo motor isreduced, and the load capacity of a joint belt is improved; the servo joint using the dual-coded-disc encoder has the advantages that the structure is compact, the production cost is reduced, the size and weight are reduced, and the application on a robot is convenient.

Description

technical field [0001] The invention relates to the technical field of encoders, in particular to a double-code disc encoder and a servo joint using the double-code disc encoder. Background technique [0002] With the rapid development of industrial automation technology, robots, as an important industrial automation equipment, are getting more and more attention and are used more and more widely. In robot-related technologies, the control of moving parts such as robot joints is the most important and critical. [0003] In the servo reducer, the moving parts such as the robot joints can be powered by the motor, and the motion posture of the motor and the moving parts such as the joints of the robot can be measured through the encoder, so as to realize the full closed-loop control of the moving parts such as the robot joints. [0004] In the prior art, such as patent 201620077231.7, in the servo reducer, if two encoders are used up and down to measure the rotation angles of ...
