Case : Mechanism Simulation of Pick and Place Arm mechanism

Industry: Packaging.

Customer: One of the well known machine manufacturer.

Background:
Customer had develop a new machine tool for pick and place mechanical arm to help them in packaging of their product. For that they had provided us detailed assembly of parts, and arrangement of various parts wthin the assembly.

Customer Requirments:
1). The customer initially wanted to develop CAM profile for Vertical and Horizontal motion of the pick and place arm.
2). Then assembly was to be created so as to stimulate the newly developed mechanism for checking interfernce between different parts of the assembly while in motion.
3). Bill of material was to be created for newly developed mechanism.
4). To develop a compact pick and place mechanism.

Solution:
Initially the parts were modeled using the drawing provided by the customer, then the assembly was created using modeled parts. The real challenge was to create CAM profile for required motion, which was generated using unique capability of software, by providing time and displacement as input.
Then the developed CAM profile's for horizontal and vertical displacement were used to create CAM and follower and then those were assembled to the whole assembly. After the complete assembly was created, it was simulated for checking the motion and interference between parts.
After the initial simulation of mechanism we found that by modifying some of the links and its arrangement within the assembly, we can develop a much compact mechanism with the required motion. After certain iterations we finally decided on the arrangement of the parts with in the assembly and the mechanism as the whole.
Then interfernce check was made between parts while in actual motion, and then wherever required necessary changes where made on the parts. The final bill of materila was created for the final assembly. Then the stimulated mechanism with BOM was submitted to the customer for the final approval.
