Koncept för materialpresentation till kollaborativ robot

Sammanfattning: This report is based on a bachelor’s thesis for mechanical engineers at Umeå University, done during the spring of 2019. The thesis is done at the request of and in cooperation with Sanmina SCI-AB in Örnsköldsvik.   The purpose of the project is to develop a concept for material presentation that can feed and present material to a collaborative robot that Sanmina has chosen to purchase. The robot and material presentation solution together are supposed to make up a complete automated solution. Along with this, a preferred suggestion should be presented to the layout of the robot cell.   An additional request from Sanmina was that the chosen concept should be as simple as possible with regards to electronics such as sensors, motors and the like. To explore the ways which the project could proceed, contact was established with an automated solution company. With recommendations from an expert in the field, the finalized concept could be created.   The chosen solution uses gravity to move trays with material down a slope, towards the robot. The sloped surfaces length allows them to function as storage for additional material trays, increasing the time between restocking of material. Additionally, to maximize the amount of different materials each robot can use, the solution can utilize different levels. With more than one level stacked upon the other, the robot can move the material presentation surface to access trays below.
