Embodiment Construction

[0014] The purpose of the present invention is to provide a kind of deceleration device for SCARA industrial robot, mainly aimed at four-axis SCARA industrial robot, solves in the prior art:

[0015] 1. The J4 joint depends on the harmonic reducer, which leads to the high cost of the SCARA robot;

[0016] 2. Due to the heavy mass of the J4 joint harmonic reducer and the placement at the farthest end of the arm span, there is a technical defect in the partial loss of the performance of the J1, J2 axis motors and the reducer.

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the deceleration device for the SCARA industrial robot of the present invention is arranged on the forearm 1 at the end of the robot, and includes a motor 2, a first-stage synchronous belt, a second-stage synchronous belt and a ball spline mechanism, and the motor 2 is arranged on the ...

Abstract

Provided is a reduction gear for an SCARA industrial robot. A motor is arranged on a forearm, the tail end of the forearm is connected with a ball spline mechanism through a bearing, and the motor outputs torque and rotating speed to a ball spline through a first level synchronous belt and a second level synchronous belt. According to the reduction gear for the SCARA industrial robot, an alternative solution of a harmonic drive is provided, a reducing mechanism with compound transmission through the second level synchronous belt is adopted, the barycener offset distance of the SCARA robot is reduced, and the improvement of the acceleration performance of the whole machine is facilitated; meanwhile, the reduction gear for the SCARA industrial robot has the advantages of being long in service face, high in precision, high in speed, stable in transmission, high in space utilization, low in heat productivity, low in noise and the like, the use performance is improved, and the cost of the whole machine is reduced.

Description

technical field [0001] The invention belongs to the technical field of industrial robots, and relates to a joint deceleration technology of a robot, in particular to a deceleration device for a SCARA industrial robot. Background technique [0002] Planar articulated robot, also known as SCARA (Selective Compliance Assembly Robot Arm) robot, is a robot arm used in assembly operations. In the development process of the industrial robot body, the joint deceleration device is a very critical link and one of the technical cores of the mechanical part of the entire robot. Moreover, the cost of joint reduction devices occupies a relatively large proportion in the total cost of mechanical components. [0003] The four-axis SCARA robot has three revolving joints whose axes are parallel to each other for positioning and orientation in the plane. The other joint is the movement joint, which is used to complete the movement of the end piece in a plane perpendicular to the plane. Gene...
