How The Introduction Of Robotics Changed The Pick And Place System?





Manufacturing of goods on a large scale requires efficient workers with suitable skills who can work hand in hand with the latest technologies and robotic pieces of equipment. In this article, we will be discussing an advanced pick and place system that is solving the issues related to monitoring, in-line processing, and other problems in placing the right items in the right place. So, let us begin by understanding what exactly this system is and how it differs from the manual pick and place system.

What is a Pick and Place System?

A robotic pick and place system shortens the time it takes to pick up and position components or things in different places. One can choose and put items utilized in current production facilities.  This technique upon automation assists to enhance manufacturing rates. Pick and place systems take care of routine chores, allowing humans to focus on more complicated ones. Pick and place system robots move merchandise from one spot to another quickly and precisely. Manual pick-and-place systems might necessitate repetitive activity over an extended period of time, thereby causing ergonomic concerns. High-speed pick and place robots can improve productivity while lowering manufacturing costs and alleviating ergonomic concerns.

How do Pick and Place Robots Operate?

Usually, high-speed pick and place robots installed on a platform provide the users with full access to their working area. After an upstream vision system has determined the product's orientation, it will enter the robotic work envelope. The selected product is set to its position by the robot at the desired spot using a bespoke end of arm tool. The product can pass or fail inspection depending on customer-defined length, straightness, form, and other criteria.

Different Types of Pick and Place System

These robotic pick and place systems are of different types based on the purpose or application in the industry. Let us check out the individual types hence understanding in depth its applications. 

1. Robotic arm 

The most popular sort of robotic pick and place system is a robot arm. A five-axis mechanical arm robot is used for basic pick and place operations, which include picking up things and moving them to different positions in a single plane. For more sophisticated approaches, such as when things must be rotated or re-oriented before being put in another area, it employs a robotic six-axis mechanical armed robot.

2. Cartesian robots

The Cartesian robots use Cartesian coordinates to move in three orthogonal axes (X, Y, and Z). They use any sort of linear actuator and a variety of driving systems, including belt, ball, and lead screw as their components.

3. Delta robots

Delta - Delta robots are frequently used in applications where robots collect objects in groups and arrange them in assembly patterns or containers. They feature excellent vision technology that allows them to discern between different sizes, shapes, and colors. Delta robots come in a variety of forms, but the majority feature three arms that move on four axes. They contain heavy motors attached to a frame, with lightweight arms linked to connecting rods and joints (usually ball joints) at each end of each arm to facilitate movement.

4. Fast pick robots

Fast pick robots are excellent for medium- to high-volume applications involving high-velocity product lines. Rapid vacuum pick and place systems completely automate the processing, allowing the human workforce to focus on more important tasks. They're great for fast-moving "top-off" products like promotional items or batteries. These robots are capable of picking up to 300 SKUs per hour from a pool of up to 8 SKUs.

5. Collaborative robots

Collaborative robots supplement human work by directing associates to appropriate areas and helping them through each activity. Collaborative robots help colleagues work more efficiently by optimizing routes in real-time and keeping them on target.

Applications of Robotic Pick and Place System

Here are some of the most typical pick and place robot applications and how they're employed that are worth mentioning. 

1. Manufacturing operations

Pick and place robots are utilized in a variety of industries, including manufacturing, packing, bin picking, and inspection. 

2. Assembly line maintenance

Pick and place robots are used in assembly applications to take incoming parts from one spot, such as a conveyor, and put or attach them to another piece of the object. After that, the two linked sections are moved to the next assembly location.

3. Packaging

Pick and place robots are used in the packaging process to take goods from an incoming source or a defined region and deposit them in a packing container. This is way better than the traditional packaging techniques which require a large number of workers working together and robotic precision supports to improve the efficiency of packing the goods.

4. Bin picking

In bin picking applications, pick and place robots gather components or things from bins. These pick and place robots usually have powerful vision systems that allow them to discern color, shape, and size in order to select the correct things from bins of randomly mixed goods. After that, the components or objects are shipped to a different site for assembly or packing.

5. Inspection 

Inspection robots are equipped with advanced vision systems that pick up things, identify abnormalities, and remove defective components or products by depositing them in a predetermined position. Thus the pick and place system for engine blocks ensures that in-line production meets the standards of the manufacturer such that any product with a defect or that does not meet the requirements will not join the final packing stage.

Advantages of Using a Pick and Place System

Pick and place robots' main advantages are speed and consistency. Robots upon configuration to fit individual manufacturing needs and are easily programmed, allowing them to be employed in a variety of settings. While pick and place robots come in a variety of sizes and weights, they are frequently compact and light, making them perfect for applications with limited space. Pick and place robots help in the picking and packing procedures in warehouses, helping to enhance productivity. These robotic solutions also give producers a favorable return on investment.

On the whole, robotic pick and place systems and the other semic automatic pieces of equipment help in utilizing automation for improved overall efficiency and reduce the degree of errors. Hope this article was useful in knowing about the pick and place systems along with their applications.
