Screwdriving is the second-most frequent meeting activity. However it is usually a tiresome job with many issues when completed manually. Automated screwdriving presents a extremely efficient answer… however provided that your activity is appropriate.

Meeting is a core exercise for a lot of producers and screwdriving is an especially frequent operation. Based on analysis, the one meeting activity that’s extra prevalent than screwdriving is peg-in-hole.

There are many nice causes to automate your screwdriving activity, together with improved consistency, decreased damage to staff, and excessive accuracy.

The issue is that not all screwdriving duties are appropriate for automation.

If you choose the unsuitable activity — or the unsuitable kind of computerized screwdriving machine —you can find yourself with an computerized screwdriving system that does not fit your wants.

What kind of automated screwdriving system do you want?

Folks typically get the unsuitable concept in relation to automated screwdriving. They assume that there are solely two choices: guide screwdriving or full-scale automation.

In actuality, there are a number of choices for automated, or semi-automated, screwdriving. Any of those may be appropriate to your wants. Which answer is finest is dependent upon your scenario.

Three frequent choices are:

  • Full computerized screwdriving machine — These are a sort of standard automation. So that they are typically large, cumbersome, and costly. They embrace mounted spindles and fixtures that carry out precisely the identical screwing operation each time. They are perfect for high-volume manufacturing with easy screwdriving duties that by no means change.
  • Auto-screw feeder with handheld nutrunner — That is one step up from guide screwdriving with an electrical screwdriver. The operator holds the nutrunner of their hand, which offers excessive torque to the screw. The automated facet comes from the screw feeder, which routinely feeds the nutrunner with screws.
  • Robotic screwdriving — Collaborative robotic screwdriving presents the perfect of each worlds. It’s nearly as versatile as guide screwdriving for some duties however has the excessive consistency of standard automation.

Earlier than you’ll be able to assess your specific screwdriving activity for suitability, you will have to resolve which of those 3 forms of automation you want.

5 components that make a screwdriving activity difficult for automation

What makes a screwdriving activity simple or tough for automation?

If you find yourself manually screwdriving, you won’t discover that the duty is definitely fairly complicated. Deceptively complicated.

Robotics researchers broke the duty of screwdriving down into its element components to search out which have been essentially the most difficult.

Listed below are 5 components that make a activity difficult for automated screwdriving:

1. Unclear understanding of your screwdriving activity

The primary problem comes earlier than you even begin deploying your automated answer. There are various automated screwdriving options in the marketplace. All of them share comparable properties, however some will probably be extra appropriate to your wants than others.

If you do not have a transparent understanding of your screwdriving activity, this will make it very arduous to discover a good answer to your wants.

2. Screw meting out

One problem with automation is that all the things must be offered in a managed, constant means. For instance, a screwdriving robotic requires that the screws are offered in precisely the identical location and orientation each time.

A typical answer for that is to make use of a screw feeder. This ensures that the robotic will at all times obtain a screw in the proper means. The Robotiq Screwdriving Resolution consists of the Robotiq SF-300 Screw Feeder for this objective.

If every of your assemblies requires dozens of various screw sorts, shapes, and sizes, it turns into lots tougher to dispense the screws correctly.

3. Uncommon, nonferrous screws

A associated downside is transporting the screw from the feeder to the work house. You don’t need the screw to fall from the robotic’s finish effector when it is in movement. This might result in an incorrectly assembled product.

With ferrous screws, the robotic can maintain maintain of the screw utilizing a magnetic tip. Nevertheless, this does not work for all screw sorts.

In case your activity makes use of an uncommon, nonferrous kind of screw, you would possibly wrestle to automate it simply.

4. Unusual or complicated screw alignment

Probably a very powerful and difficult facet of automated screwdriving is alignment. The screw have to be completely aligned with the bolt or gap. Whether it is incorrectly aligned, faults like cross-threading can happen, ruining the workpiece.

Your chosen automated screwdriving system ought to have the ability to precisely place and align the screw, in addition to account for errors.

In case your screws are very tough to align for some cause, it could be arduous to automate the duty with out including further parts or fixtures.

5. Extreme torque required

There are three fundamental phases to any screwdriving movement: Alignment, rundown, and tightening.

Within the closing tightening step, the automated system applies torque to the screw, fixing it firmly in place. Your system ought to have the ability to help the torque required. For instance, the Robotiq Screwdriving Resolution can apply torques as much as 4 Nm.

In case your screws require very excessive torques, they are going to want specialist nutrunners to account for this.

How one can assess your screwdriving activity for suitability with a robotic

There are some clear indicators {that a} screwdriving activity is appropriate for automation.

Some good guidelines of thumb once you assess a activity for robotic automation are…

  • The half will be fixtured
  • The duty is easy
  • Just one human is changed
  • Makes use of a single kind of screw
  • You have got operator buy-in
  • Extra flooring house is accessible
  • Has a excessive influence
