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.
Resources used:
Software: I-DEAS 8 Design / Assembly / Mechanism Design.
Time Taken: 4 Working Days.
