Screw assemblies are extraordinarily frequent in an meeting line. Over the course of a single shift, for instance, operators can simply be fastening over 5,000 screws even when the variety of screws per half is lower than a dozen.
You would possibly really feel like you may simply “throw” some automation on the downside. Perhaps a standard automated meeting machine sounds good? Perhaps you are already desirous about utilizing a robotic?
We discover that these individuals who select screwdriving as their first robotic utility are typically extra technically minded. If that is you, possibly you have already got expertise deploying robotics or a minimum of working with automation.
No matter your stage of robotics experience, there are some things you’d be smart to keep away from when selecting screw meeting automation.
Listed here are 7 of the highest issues to look out for:
1. Attempting to do an excessive amount of with meeting automation
Maybe you could have some large plans to your meeting robotic. You might have recognized a fastening process that you simply actually wish to take out of the arms of your staff. You might be eager to automate it with a robotic.
First, ask your self: Is that this a posh process for a robotic?
As meeting consultants clarify “Typically the superior functionality and adaptability of a robotic may cause a designer to over process the robotic and make the work cell too advanced.
Strive to not do an excessive amount of together with your screwdriving robotic, a minimum of at first. It is a lot better to ace a easy utility first and construct on that success later.
2. Mis-sizing the robotic and equipment to your process
There are quite a lot of robots accessible in the marketplace. Some come as a part of off-the-shelf utility kits for automated fastening and others require you to deploy all the things your self.
No matter kind of robotic system you select, ensure you’re utilizing the right-sized robotic and equipment to your particular screw meeting process.
One useful methodology for sizing any automation system is to make use of the acronym LOSTPED. This stands for: Load, Orientation, Pace, Journey, Precision, and Atmosphere.
You may assess your fastening process with reference to these 7 classes. It will provide you with a greater thought of how effectively a specific resolution will meet your wants.
3. Including meeting automation with out your staff
Maybe the largest mistake some corporations make is to only announce automation with out first getting their groups on facet. This can be a downside as a result of it units up a possible atmosphere of distrust from the beginning.
Essentially the most profitable deployments of screw meeting robots are these the place the groups had been concerned proper from the beginning of the mission.
Your staff is stuffed with individuals with a large amount of talent, data, and experience. Once you enable them to contribute to the robotic deployment, they can assist you to make your meeting automation an enormous success.
4. Choosing the fallacious finish effector kind to your screws
Not all screwdriving finish effectors are appropriate with all kinds of screws.
The best instance of that is non-ferromagnetic screws. Many robotic fastening techniques use magnetic screwdriving instruments to maintain the screws mounted to the tip of the robotic’s finish effector. In case your fixings aren’t ferromagnetic, they’ll possible want a vacuum screwdriving device or one other different.
Keep away from making assumptions about what shall be attainable with a specific system — it is a lot better to only ask and ensure. With the correct info, you can be certain to choose the correct resolution for you.
5. Utilizing very excessive torque screws
Torque is a core property for any automated fastening system. You want your resolution to have the ability to present satisfactory torque or it is going to be unsuitable to your process.
The Robotiq Screwdriving Answer, for instance, can present between 1 N to 4 N of torque to the screws. That is excellent for many small fastening duties. Nevertheless it is not appropriate for very excessive torque screws.
Some screwdriving purposes require a lot larger torque rankings than this, reminiscent of some automotive, aerospace, or shipbuilding fastening. Be certain your chosen automation resolution can meet your torque necessities.
6. Cramming fastening operations right into a small house
A typical problem for automated fastening techniques is when all of the parts are squashed very shut collectively on the workpiece. This leaves the robotic with little or no house to maneuver round and may make the robotic deployment advanced.
Indicators that your fasteners lack ample house embody when they’re fitted in deep recesses, when they’re near vertical partitions, and when screws are very shut collectively.
A very good rule of thumb is to have 0.5 inches of clearance round the place the top of the screw is put in. However the more room your robotic has to maneuver round, the better it is going to be to automate the meeting.
7. Choosing advanced and/or low influence duties
Is your meeting process really going to be price automating?
It is surprisingly frequent for engineers to decide on the fallacious duties once they automate a fastening process for the primary time.
In some circumstances, they decide duties which are too advanced to automate — setting themselves up for each a troublesome deployment process and the next probability of failure. In different circumstances, they select a process that may have little or no influence on their processes, making it laborious for them to show a transparent return on funding.
Choose a fastening process that’s each excessive influence and easy to deploy.
Now that you understand some issues to keep away from… how do you get began together with your first screw meeting automation mission?
A very good place to begin is to obtain a duplicate of our free eBook How you can Automate a Screwdriving Cell. This guides you thru the method of designing and deploying an meeting robotic to your facility.
