Automation has been greatly used in almost all industries to make lives easier. The nature of work in the manufacturing industry has changed over the years. The majority of the tasks in factories nowadays are done by machines. Robotic arms, such as pick and place robots, are replacing human arms to complete tedious and repetitive tasks. Thus, preventing injuries and freeing human workers for tasks that need more critical thinking.
Pick and place industrial robots can produce more accurate results and drive the industry further. EVS, a leading industrial robotic arm manufacturer in China, offers innovative pick and place robotic arms that are suitable for a wide range of applications in various industries. Our pick & place robots come in various reach and payload capacities to accommodate your business’ unique needs.

Pick and place arms are common in modern production plants. Pick and place automation helps in speeding up tasks that involve picking up items or components and transporting them into other locations. This greatly increases production because robots can handle monotonous tasks without the need for an operator. They can also be configured to accommodate different plant layouts and product types.
There are 5 common types of pick and place robots (robotic arms, cartesian, delta, fast pick, and collaborative robots) but the most common ones are robotic arms. Robotic arms are typically designed to have 4 to 6 axes.
Robotic arms with 4 axes are used in standard pick and place applications that move objects to another location in one plane. On the other hand, 6-axis pick and place robots are used for applications with more complexity where objects need to be re-oriented or twisted before they are placed in other locations.
Pick and place robots are normally mounted on table stands and positioned in a place where they can reach various areas to complete tasks. They can be designed and installed with any end-of-arm tooling depending on the application where you are going to use them.
Moreover, they are heavily dependent on joints – the components in a pick and place robot that join 2 rigid bodies and can either be linear or rotary. These joints will determine the robot arm’s movement as well as its components’ degree of freedom. All pick and place robotic arms have the following major components:
This is the robot’s entire mechanism that allows the robot to move. The joints of the manipulator are its movable components that enable motion between the robot’s links. Moreover, the manipulator consists of a base, arm, and a gripper.
The controller is the robot’s brain that operates its arm/s. It controls the manipulator’s movements and the robot joints’ positions. It can either be electrical, hydraulic, or mechanical.
Electrical systems are the most popular types of controllers today because they are accurate, quiet, clean, convenient, and reasonably fast. They have a programmable controller that stores instructions to be performed in the operations. EVS robots have electrical control units.
This is like a human hand that grasps and secures items while the robot performs its task. Its strength and shape will depend on the type of object to be handled and the task the robot is going to perform.
Pick and place robots come with advanced technologies and sensors to accurately identify, pick, and move items to and from different places. They help ensure that the whole robot will function smoothly.
You might be wondering why you, as a manufacturer, should buy an industrial pick and place robot to automate your manufacturing line. Below are the main reasons why you need pick and place robots in your factory along with their benefits:
The top reason why manufacturers should buy a pick and place robot is because of speed. Pick and place robots can multitask because they can have multiple heads along with several advanced features. Through these features, the robot can quickly swap different modules. Moreover, pick and place robots are able to handle a wide array of components. In theory, they can handle up to 130,000 components/hour (cph).
Accuracy and precision are the 2 ways of measuring error. Accuracy pertains to how far a task is from the desired outcome while precision involves completing a task within a small margin of error. Pick n place robots offer both highly accurate and precise results. Their programming ensures that their mechanisms deliver reliable and consistent performance.
Pick and place robots provide extreme flexibility. You can easily program them to handle different specifications, movements, and dimensions you want. Thus, they can accommodate various operations and components in different sizes and shapes. Moreover, their arms can move laterally, vertically, or horizontally.
Pick and place robotic arms help in streamlining manufacturing processes by automating various tasks in the factory. Their speed and consistency eliminate unnecessary expenses which allow you to save more money. Although they are expensive investments at first, they are ensured to provide you good ROI in the long run.
Both big and small pick and place robots are being used in manufacturing facilities to complete tasks such as assembly, bin picking, packaging, and inspection in various industries. Let us take a look at how pick and place robotic arms are used in these applications below:
For assembly processes, pick and place assembly robots pick up parts from a conveyor and affix the parts to another component of the product being assembled. Once the components are joined together, they are moved to the succeeding assembly area.
Instead of grabbing parts from a conveyor like in assembly applications, bin picking robotic arms grab parts from bins. They are usually equipped with vision systems that help them distinguish colors, shapes, and sizes so that they can properly pick objects even from bins with random items. After picking the items, they are transported to other locations either for packaging or assembly.
Packaging pick & place robots grab products from incoming sources, such as conveyors, or from other designated areas and then place them in packaging containers at high speeds.
Lastly, inspection systems also use pick and place robots with added vision technologies to grab products, detect defective items, and remove them from the production line by transferring them to another location.
