The Industrial Pick and Place robot buyer's guide

Robotic arms ABCs

A robotic arm is an automated system designed to grasp and move objects quickly and precisely. While this may seem futuristic, assembly lines commonly use these robots day in and day out. Moreover, they can also aid other types of operations'such as logistics'if they're fitted with the right mechanisms and programs. 

With competitive price and timely delivery, Fuxin Intelligent sincerely hope to be your supplier and partner.

Let's break down their key components:

  • End-effectors: These are the gripping mechanisms that attach to the robot's arm and allow it to grasp and hold objects. Different types of end-effectors include vacuum grippers for smooth objects, force-controlled grippers for objects of various shapes and sizes, and magnetic grippers for ferrous objects with magnetic surfaces.
  • Joints: These are the flexible connectors that allow the robot's arm to move and maneuver. The number and type of joints determine the arm's range of motion and overall dexterity.
  • Motors: They drive the robot's movement, converting electrical energy into mechanical motion, enabling the robot to precisely position its arm and grip objects.

What is an Industrial Pick and Place robot?

An Industrial Pick and Place robot is a specialized robotic arm typically mounted on a stable stand with end-effectors that allow it to grasp and move objects from point A to point B. 

These automated machines utilize end-effectors like vacuum grippers, force-controlled grippers, or magnetic grippers to grab items, and then maneuver them as needed. They can either operate on a fixed path or use sensors to adjust to varying positions. 

If you're a logistics or manufacturing professional, you probably can give us a TED talk about the pick and place process. But, an Industrial Pick and Place robot can help you supercharge your workflow by operating fast, accurately, and around the clock.

Let's take a look at how.

How can an Industrial Pick and Place robot help logistics? 

Robot arms have several advantages over human labor, such as: 

  • Higher throughput and productivity because they can operate continuously without those pesky smoke breaks.
  • Improved precision. Robots are fantastic at high-precision tasks and can place objects exactly where needed over and over again.
  • Better use of space. An Industrial Pick and Place robot can reach areas that may be difficult or outright dangerous for humans. 
  • They save time and money. Although at first, you may need to pay a pretty penny, you will save money in the long run due to reduced labor costs and increased efficiency. 

Furthermore, you can use an Industrial Pick and Place robot for a wide range of applications. These versatile systems can streamline your picking, packing, and palletizing processes to optimize productivity. 

If you're looking to implement robotics in your workspace, understanding your options is essential to finding what works for you.

Types of Industrial Pick and Place robots

There are several types of Pick and Place robots, each with its specialties and strengths.

Robotic arms: The most common type, used for basic single-plane pick and place tasks. Five-Axis arms handle standard tasks, while Six-Axis arms handle more complex ones.

Cartesian robots: Similar to Six-Axis arms but move in even more planes of motion, offering better positioning accuracy.

Delta robots: Equipped with advanced vision technology to identify and pick items based on size, shape, and color. Ideal for assembly and packaging applications.

Fast pick robots: Perfect for high-volume applications, picking up to 300 items per hour from a pool of up to 8 SKUs. Great at handling fast-moving items like promotional products or batteries.

Collaborative robots: Work alongside humans, optimizing routes and guiding associates through tasks, boosting efficiency and productivity.

What can you use Industrial Pick and Place robots for?

While the most common use of Industrial Pick and Place robots is manufacturing, they have many possible applications. 

Their built-in versatility and precision make them perfect tools for various industries, such as: 

  • Assembly: Pick and Place robots are widely employed in assembly lines to streamline the process of joining components. They grab incoming parts from conveyors or designated locations and precisely position them for assembly.
  • Packaging: These robot arms pick up products from incoming sources and place them immaculately in designated containers.
  • Bin picking: Advanced vision systems enable industrial Pick and Place robots to identify, grasp, and extract specific items or parts based on their color, shape, size, or other distinguishing features. Then, these extracted items go on to further assembly or packaging. '
  • Quality control: Pick and Place robots can precisely pick up products and meticulously scan them for flaws to remove any defective items from the production line.

5 Things to Consider Before Purchasing a Robot

I might be dating myself a bit here, but back in the s, there was a belief among machinists like myself that robots were for repetitive work. They were for big companies (with deep pockets) entrenched in automation and efficiency. We pictured car assembly plants with continuous streams of parts moving along an automated line, with robots painting, bonding and assembling different makes and models. The whole thing looked and sounded expensive, exclusive and complicated, and most of us wrote robots off then and there.

Today, things are just a bit different. (You know I'm being sarcastic.)

Technology is booming. Machine shops are becoming more automated. Robots are more affordable. Information is more accessible, and machine learning is no longer science fiction. Everyone is jumping in ' the herd has heard the call ' but, as with most things, people are jumping on the train blindly. So, before you equip your machine shop with the latest and greatest robots, there are a few things you need to take into consideration.

Application

This is the big one: What do you want your robot to do? Other questions to ask yourself include: How heavy of a load do you want the robot to lift? Is it in a hostile environment such as a welding application? What accuracy should the robot have? Can you use a cobot instead of an industrial robot? Will it be working alongside humans? The list goes on. You must have a clear idea of what you want the robot to do.

Integration

The average machinist cannot 'hook up' or integrate a robot to a CNC machine by themselves, that is unless they are gifted by the divine. I'm going to assume that is not the case, so this is an important consideration: Depending on who you use and how good they are, the project can end up as a great success or a giant failure. Be sure to start small and keep it simple, with tasks such as loading and unloading a lathe. Remember, robots can be reprogrammed very easily, and the scope of work can increase as you become more familiar with the technology.

Ease of Programming

They're not building robots like they used to. Today, most robots are user friendly and accessible. You don't need to have a Ph.D. to program a robot. Some of us used to think that was the case, but it's just not so anymore. Many robot manufacturers have online courses and academies that teach you how to program their products, and while some programming systems are more complex than others, they are mostly very user friendly.

When choosing a robot, assess your programming comfort level and test it out. Don't run before you can walk. The more complex the robot's programming, the more likely it is that your project may not work out. This is especially true given that you may have to constantly reprogram your robot as you learn to expand the tasks and movements it performs.

Cost of Support

There is no denying that support has a cost, but many manufacturers use support as a profit center. Avoid companies that use it as such, especially if you get the feeling that the cost of dealing with them is going to greatly increase the cost of the robot. How can you tell? When you get your quote for the robot, large training expenses with service and support fees will give it away. Like I said, support has a cost, but quality robot manufacturers will offer help and assistance as part of the sale. If they don't, well then, it's your call.

Partners in Innovation

When I first started buying equipment, this wasn't even on my radar. Now, it's an integral part of the purchasing decision. In this case, when I talk about partners in innovation, I'm talking about how much a robot manufacturer collaborates with other innovative companies. What I've learned over the years is that it's a big red flag when a manufacturer wants to supply and do everything themselves. Ultimately, they want to capture all your money. Some manufacturers like to create a closed circuit so you have to rely on them. By only using their own technology, they don't partner with innovative companies that have strengths in other areas. There are so many innovative things happening in the manufacturing industry ' you want to maximize your benefit from it. It's something to consider, and something that will make your robot integration as successful as possible now and in the future.

In order to make the integration of robots into your machine shop successful, you need to consider each of these five points respectively. I personally know many companies that have failed in the integration of robots because they neglected one of these considerations. Don't be like that. Don't rush in without doing your research. Don't set yourself up for failure. Start simple, and you'll be successful.
