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 may really feel like you possibly can simply “throw” some automation on the downside. Possibly a standard automated meeting machine sounds good? Possibly you are already fascinated about utilizing a robotic?
We discover that these individuals who select screwdriving as their first robotic utility are usually extra technically minded. If that is you, perhaps you have already got expertise deploying robotics or no less than working with automation.
No matter your degree of robotics experience, there are some things you’ll be sensible 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’ve some huge plans on your meeting robotic. You have got recognized a fastening activity that you just actually need to take out of the fingers of your staff. You’re eager to automate it with a robotic.
First, ask your self: Is that this a fancy activity for a robotic?
As meeting specialists clarify “Generally the superior functionality and suppleness of a robotic may cause a designer to over activity the robotic and make the work cell too advanced.
Strive to not do an excessive amount of together with your screwdriving robotic, no less than 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 on your activity
There are plenty of robots obtainable available on the market. Some come as a part of off-the-shelf utility kits for automated fastening and others require you to deploy all the pieces your self.
No matter sort of robotic system you select, be sure you’re utilizing the right-sized robotic and equipment on your particular screw meeting activity.
One helpful methodology for sizing any automation system is to make use of the acronym LOSTPED. This stands for: Load, Orientation, Velocity, Journey, Precision, and Atmosphere.
You possibly can assess your fastening activity close to these 7 classes. It provides you with a greater thought of how properly a selected answer will meet your wants.
3. Including meeting automation with out your group
Maybe the most important mistake some firms make is to simply announce automation with out first getting their groups on facet. It is 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 venture.
Your group is filled with individuals with a large amount of talent, information, and experience. If you enable them to contribute to the robotic deployment, they may also help you to make your meeting automation an enormous success.
4. Selecting the improper finish effector sort on your screws
Not all screwdriving finish effectors are suitable with all kinds of screws.
The only instance of that is non-ferromagnetic screws. Many robotic fastening methods 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 probably want a vacuum screwdriving software or one other different.
Keep away from making assumptions about what shall be doable with a selected system — it is a lot better to simply ask and be certain. With the precise info, you can be certain to select the precise answer for you.
5. Utilizing very excessive torque screws
Torque is a core property for any automated fastening system. You want your answer to have the ability to present satisfactory torque or it will likely be unsuitable on your activity.
The Robotiq Screwdriving Resolution, for instance, can present between 1 N to 4 N of torque to the screws. That is excellent for many small fastening duties. However it is not appropriate for very excessive torque screws.
Some screwdriving purposes require a lot larger torque rankings than this, corresponding to some automotive, aerospace, or shipbuilding fastening. Be certain your chosen automation answer can meet your torque necessities.
6. Cramming fastening operations right into a small area
A typical problem for automated fastening methods is when all of the elements are squashed very shut collectively on the workpiece. This leaves the robotic with little or no area to maneuver round and might make the robotic deployment advanced.
Indicators that your fasteners lack ample area 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 pinnacle of the screw is put in. However the extra space your robotic has to maneuver round, the better it will likely be to automate the meeting.
7. Selecting advanced and/or low impression duties
Is your meeting activity really going to be price automating?
It is surprisingly frequent for engineers to decide on the improper duties after they automate a fastening activity for the primary time.
In some circumstances, they choose duties which are too advanced to automate — setting themselves up for each a troublesome deployment activity and a better probability of failure. In different circumstances, they select a activity that may have little or no impression on their processes, making it laborious for them to display a transparent return on funding.
Choose a fastening activity that’s each excessive impression and easy to deploy.
