Problems solved by technology

The coordinated movement of the six branch chains can make the moving platform move in six degrees of freedom relative to the fixed platform, but there will be gaps between the ball head and the ball socket connected by the ball pair due to insufficient processing and / or assembly accuracy. Due to a certain gap, the contact surface between the ball head and the ball socket cannot always be tightly fitted, which is prone to wear and tear, causing the moving platform to vibrate during the movement, thereby reducing the stability of the parallel robot movement and the positioning accuracy. This makes it difficult for this parallel robot to be used in occasions requiring high precision

Abstract

The invention discloses a machine vision parallel sorting robot. The machine vision parallel sorting robot comprises a box body assembly (1). A robot horizontally-moving platform (7) is fixedly connected to the upper portion of the box body assembly (1). A driving connecting rod (9) is arranged parallel to the robot horizontally-moving platform (7). The driving connecting rod (9) is connected with connecting rods (10). Gaps between the connecting rods (10) are eliminated through a crossed steel wire (11). In the installation process, the gaps between the connecting rods are eliminated through pre-tightening of the crossed steel wire, abrasion is effectively reduced, the algorithm of the parallel robot is optimized, a front arm speed reducer and a servo motor are integrally designed, and the speed and accuracy of the robot are improved.

Description

technical field [0001] The invention relates to a robot, in particular to a machine vision parallel sorting robot. Background technique [0002] With the rapid development of modern industry, high-performance robots have been widely used in industrial production. They can be used to quickly sort and carry items, thus saving a lot of manpower and improving production efficiency. At present, most of the sorting robots widely used in industrial production are series robots. At this stage, parallel robots can realize functions such as high-speed sorting and automatic visual judgment. [0003] However, the existing parallel robots generally include a fixed platform, a moving platform, and six branch chains connected in parallel between the fixed platform and the moving platform. The fixed platform is generally fixed, and the six branch chains can perform telescopic movements, including A moving pair and a ball pair connected to the fixed platform and the moving platform respecti...
