Problems solved by technology

[0002] Assembly in a narrow space has always been a difficult problem in the field of automated assembly. In a narrow space, due to reasons such as low visibility, small visible range, and large axial depth of installation, other assembly tools must be used for installation. However, due to Assembly tools are not coordinated by the human eye, making manual tool manipulation difficult
When the axial installation depth is greater than the reach of human hands, it is basically impossible to install with ordinary installation tools

Abstract

The invention discloses a narrow space bolt positioning and installing robot and a control method. The narrow space bolt positioning and installing robot comprises an installing platform, a fixing plate, a tool fixture, an industrial robot, a movement module and a controller. The control method comprises the steps of firstly moving a bolt and a washer to an axis position of a driven gear, supporting the bolt and the washer through a spring force, then downwards moving a connecting block, installing the bolt onto the driven gear, and resetting a spring to fix the bolt; then vision guiding for avoiding obstacles through a camera, and sending the fixture to a preset position capable of shooting a thread hole through a robot arm; and adopting the robot for automatically positioning a target thread hole, sending the position of the thread hole to the robot arm and locking the position, rotating the fixture to enable the bolt to align at the thread hole, starting to move downwards under the drive of the gear, stopping the assembling of the first bolt when a sensor touches a bottom plate, automatically carrying the robot to a preset position of a next thread hole through a module motor, and carrying out the next round of assembling until all assembling is finished.

Description

technical field [0001] The invention relates to the field of industrial robots, in particular to a robot for positioning and installing bolts in a narrow space and a control method thereof. Background technique [0002] Assembly in a narrow space has always been a difficult problem in the field of automated assembly. In a narrow space, due to reasons such as low visibility, small visible range, and large axial depth of installation, other assembly tools must be used for installation. However, due to Assembly tools do not get the cooperation of the human eye, making manual handling of the tools quite difficult. When the axial installation depth is greater than the reach of human hands, it is basically impossible to install with ordinary installation tools. Therefore, the prior art needs to be further improved and perfected. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a robot for positi...
