Increasing competitive in market and variety demand of customer cause to need increase flexibility of the system. In this point, robots help the system increase flexibility. In the recent years, robots have been widely used in assembly systems instead of workers for certain operations and they are called robotic assembly lines (RAL). An assembly robot may preform on task 24 hour without fatigue. A general-purpose assembly robot can perform different tasks with use of certain tools but different type of robot can complete task with different performance.

In the assembly system, robots are able to provide enhancement on flexibility of the system and automation. Each robot can perform different performance on the same tasks due to their capabilities. Therefore, the balancing robotic assembly line (RALB) problem consists two main works, which are assigning tasks to workstations, and allocation robots in workstations. 

In our process of designing and commissioning a system, the conflict objectives, minimizing cycle time, number of workstation and robot cost, are considered.

The allocation of the suitable robot in the workstation is very important for RAL. The aim of use of robot is to increase productivity, quality of product, manufacturing flexibility, safety. The balancing robotic assembly line (RALB) problem includes two main works, which are assigning task to workstation and allocation robots in workstations because different robots perform different performance on same job. 

These are the steps we set up the Assembly Robot: 

There are many robotic configurations available for assembly robots.  

We first select the applications:

1. Six-Axis Robots provide optimal strength, flexibility, and reach to complete the desired task. They are compact, highly dexterous, nimble robots to engage assemblies from all angles. They are playing an ever-increasing role in the assembly space. 

2. SCARA Robots stand for “Selective Compliant Assembly Robot Arm.” They are 4-Axis robots  that are ideal for high-speed assembly. It gets its name as the arm is selectivity compliant in the X-Y direction but rigid in the “Z” direction to help with many types of assembly operations, such as inserting a round pin in a round hole without binding.

3. Delta Robots have smaller payloads, but unparalleled acceleration and speed. They resemble a ceiling-mounted spider as motors in the base move the three linked arms. Its major mechanical axes act on the robot face-plate in parallel rather than in series which allows it to be quick and precise. Speeds of 10 millimeters per second are typical while also accommodating improved repeatability at the tool tip which means it is perfect for small part assembly. 

4. Dual Arm robots have helped to ease complex assembly applications by doing tasks such as holding one part and inserting another part into it. For flexible parts or components, such as tubing and hoses, dual arms can work together to simplify the tooling and enable the application to be done in a simpler way.


5. Collaborative robots are a rapidly emerging area of industrial robotics also entering assembly space.  They are specially designed to operate alongside human coworkers on an assembly line without the need for safety guarding. 


Choose Assembly Software as per the system design

The machine vision software available is incredibly beneficial in guiding robots to precise part location, and inspection. In addition, force sensing equips assembly robots with the sense of touch in all 6 degrees of freedom.  It measures the forces and torque applied at the EOAT and offers the robot control system feedback for hybrid force-compliance movement control of the end-of-arm tool. These options are transforming assembly lines and clean rooms.

Consider electronics whose assembly tolerances are getting tighter as the parts and pieces are getting smaller.  The necessary precision, consistency, and minimal cost required all make robotics assembly a critical part of the production process.

Fortunately, the complex assemblies and sensor-based technologies are getting better, cheaper, and more user-friendly. The user interface is now advanced enough so a highly skilled worker is no longer necessary. Visual serving has enabled the robot world to achieve precision assembly 

Installation of the right EOAT

End of arm tooling can be purchased standard or customized for each assembly robot to cater to the manufacturing requirements. They can range from grippers, vacuum cups, 3-jaw chucks, high-speed spindles, cylinders, or drills.

A standard EOAT is mass produced and can easily be ordered as we work with several different suppliers to ensure that customers get the best available. A standard EOAT can be easily accessed and will not lengthen the build time for your robot, however it is designed to fit a number of products, and may not be the perfect fit for your specific needs.

If you choose the customized route, engineers designing the system decide which end effectors would be best for the application and then fabricate and build to the specification. This will add time to the build but ultimately a custom EOAT can produce better functionality during production. 

Choosing the right EOAT can ensure groping is done correctly.  This is a key feature where the robot moves the EOAT close to the location of assembly and transitions into groping where the robot makes a pattern around the part  where it’s supposed to be assembled. It moves slowly and progressively, in  different pre-programmed patterns, to make contact and sense the forces, motion,  and direction, and then act according to drive the parts together. 

The  important thing is to spend the money on the correct EOAT for the job since  sensing and control capability are the key.


Design the Workspace

Assembly  is able shrink the footprint of work cells by creating complex systems that  combine multiple operations by using different tooling. Ultimately, a part  produced in this type of system gets assembled and checked, all at once. 

 A robot workcell is necessary to complete a system that includes the robot, controller, and other peripherals such as a part positioner and safety environment. Custom cells are built to customer specifications and allow for the limitations and challenges often found in an industrial setting. They are ideal for applications a standard workcell would not be able to perform.​

Agile robots augmented with force sensors and vision are unstoppable. Watching coordinated assembly robots work tirelessly, accurately, quickly, and precisely is the reflection of a very promising future for automation.
