Redesign of Three-Axis Robot and Its Picking Tool (English)
Abstract [en]

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges. The idea behind the solution of Robot 1 is also to be able to apply it onto existingmachinery without too much interference. Robot 2 is significantly more advanced and alsoimplies considerable material changes. The advantage of Robot 2 is that it takes into accountboth the problems with the X-axis and Y-axis, and should absolutely be considered on newmachines, but also for existing machines. For the picking tool the thesis presents the solutionin the form of both a modified existing vacuum tool and a brand new pneumatic gripper forRobot 2 which differ from the vacuum system. I think that the vacuum tool presented shouldbe considered to be implemented even if no other modifications are made on the robotbecause of its simple construction.The thesis presents the functions and problems with the current robot and its picking tool.For the described problems the different solutions have been presented, partly by findingcompletely new market components but also through new self-designed components.During this time, choices of materials and material dimensions have been based onoverestimates and previous material selections, which later were controlled by using FEManalysisin CAD-environment.The work is considered to have gone well and the goals that have been set have beenachieved in a satisfactory manner.
