Intelligent assembly system and intelligent assembly method using repair workshop robot

Abstract

The invention belongs to the field of assembly using a repair workshop, and particularly discloses an intelligent assembly system and intelligent assembly method using a repair workshop robot. The system comprises an intelligent AGV, an integrated operation module, a tray material module, a material port and a control module, wherein the integrated operation module comprises a grabbing and assembling robot, an automatic nail feeding device, a tightening robot and a fastening bolt marking robot; and the control module is used for planning an operation track according to the operation type, andcontrolling the intelligent AGV, the integrated operation module, the tray material module and the material port to work cooperatively according to the operation track. The method comprises the following steps of planning a movement path of the intelligent AGV, grabbing mounting materials, mounting fasteners on fastening holes of the mounting materials and fastening, and marking the fastened fasteners. According to the intelligent assembly system and intelligent assembly method using the repair workshop robot, an automatic assembly process of parts, an automatic screwing process of screws andan automatic anti-loose marking process of the fastened screws are combined, so that the labor is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the field of assembly in a maintenance workshop, and more particularly relates to an intelligent assembly system and method for a robot in a maintenance workshop. Background technique [0002] At present, in the operation and maintenance workshop of CRH3 Harmony and Fuxing EMUs, there are the following problems in the installation process of the axle box end cover: (1) Each station is independent of each other, and the work is scattered and the efficiency is low. At the axlebox end cover inspection station in the maintenance and repair workshop, the three steps of picking and assembling parts, batching and assembling bolts, and marking anti-loosening bolts are still the main procedures of motor vehicle maintenance. At present, the site is a multi-person operation mode, and each operation process needs special personnel to be responsible. There is a large demand for operators, and the operators have to run around the train with ...

AI Technical Summary

Problems solved by technology

[0002] At present, in the operation and maintenance workshop of CRH3 Harmony and Fuxing EMUs, there are the following problems in the installation process of the axle box end cover: (1) Each station is independent of each other, and the operation is scattered, and the efficiency is low

At present, the site is a multi-person operation mode, and each operation process needs special personnel to be responsible. There is a large demand for operators, and the operators have to run around the train with tools and materials. The labor intensity on the site is relatively high, and multiple groups of people There is also the situation of cross-operation, which needs to avoid each other, and the operation efficiency is low

(2) The bolt tightening operation of the axle box end cover cannot prevent mistakes in the bolt tightening sequence

At present, in the repair and maintenance workshop of the EMU, during the maintenance operation process of the axle box end cover, when the axle box end cover is installed, the fastening bolts are tightened by workers holding hand tools; because it is manual work, it cannot Absolute control and error-proofing of the bolt tightening sequence should be achieved. If the control of this step is unfavorable, gaps will appear between the end cover of the axle box of the EMU and the joint surface of the axle box. cause security incident

(3) After the bolts are tightened, the anti-loosening marks are marked, which is labor-intensive and time-consuming

At present, in the operation and maintenance workshops of various bullet train depots, after the axle box end cover is inspected and installed, and the bolts are tightened, the workers rely on the workers to hold the syringes and mark the bolts that have been completed one by one with anti-loosening marks. The number of bolts is large , the work is intensive, time-consuming and labor-intensive
