2. Introduction: Automated Assembly
The use of mechanized and automated devices to perform the various
assembly tasks in an assembly line or cell
Most automated assembly systems are designed to perform a fixed sequence of
assembly steps on a specific product that is produced in very large quantities

3. Automated Assembly - Application
Characteristics
Where Is automated assembly appropriate
• High product demand
• Stable product design
• The assembly consists of no more than a limited number of components
• The product is designed for automated assembly
Advantages Of Automated Assembly
• High production rate
• High product quality and precision
• Low cost of production
• Not create the risk to the operator

4. The type of work transfer system that is used in
the assembly system:
 • Continuous transfer system
 • Synchronous transfer system
 • Asynchronous transfer system
 • Stationary base part system

5. System Configurations
1. In-line assembly machine
2. Dial indexing machine
3. Carousel assembly system
4. Single-station assembly cell

6. In-line assembly machine
 A series of automatic workstations located along and
in-line transfer system

7. Dial indexing machine
Base parts are loaded onto
fixtures or nests attached
to a circular dial table, and
components are added at
workstations located
around the periphery of
the dial as it indexes from
station to station

8. Carousel assembly system
A hybrid between circular work flow of dial indexing
machine and straight work flow of in-line system

9. Single-station assembly cell
Assembly operations are performed on a base part at a
single location
 A robot is sometimes used as the assembly machine

Abstract :
 The current process of mounting a wheel in an automotive
industry is done by manually which is difficult and time
consuming .
 In order to over come this problem automated wheel assembly
system with PLC is used to reduce human effort , time and
energy

11. Introduction
 There are many challenges to automate
the wheel loading process
 When the car is moving on the
production line as it tends to move at
random speed along x and y direction
 The automated loading system should
be able to track the random motion of
the car accurately
 since it is a final step of whole
assembly thus small damage to the car
could be a big loss
 Hence more intelligent industrial robot
system have to be developed for
complex assembly

12. Methodology
 The system includes a ABB IRB6600(7 axis) robot with sensor ,controller
and conveyor
 Initially the car position is identified by the robot using IR sensor and
motion is tracked.
 Since the wheels are loaded randomly into station the robot picks the wheel
in required position and orientation by robot gripers then moves towards
car

13.  To perform an assembly, the robot has to be controlled to
approach the moving part.
 Therefore, force control along the Z axis is applied to control
the motion of the robot to perform the wheel loading process.

14. Conclusion
 In this paper, an automated wheel loading system is developed based on the
synergic combination of visual servoing and force control strategy.
 Visual servoing is used to track the 2D motion of the car on the conveyor.
Experiments were performed successfully and the results demonstrated that
the developed technology can be used for wheel loading.
 Since huge amount of time and resource can be saved using the developed
robotic system, this innovative technology will have great impact in the
automotive industry, especially when automotive manufacturing is facing
difficulties

15. ASSEMBLY LINE PRODUCTION IMPROVEMENT BY
OPTIMIZATION OF CYCLE TIME

Abstract
 Automobile manufacturing organizations are currently Facing a necessity to
respond to rapidly changing customer needs, desires and fluctuating market
demand.
 As customer demand higher quality, shorter delivery time, higher customer
service level and lower prices.
 organizations must need to develop new methodologies allowing them to
remain competitive and flexible simultaneously so that they can respond to
the new demands
 This requirement is focusing on optimization of cycle time, reduction non
value added work Continuous Improvement.

16. Introduction
 Production improvement in the any sectors depends on man, machine
,material, methods and management.
 Cycle time is one of the important data for the line balancing at and
production line. Cycle time is the time it takes to finish one product
 Reducing cycle time requires eliminating or reducing non-value-added
activity like repair due to defects, machine set-up, inspection, test and
schedule delays.
 This elimination is done through
1. Process analysis
2. Work analysis
3. Motion analysis

17. CASE STUDY
 TKAP- R transmission planned to increase the production
capacity from 708/day to 775/day. The main basic theme is to
improve the productivity through 3M’s elimination at
transmission line to meet customer demand
 As per analysis study of assembly line conclude wastage of
machinery, material, worker and production methods and
optimize cycle time.
 In the case study small changes can adopt with low cost
automation creative think in small modification.

18.  At the stage of before implementation of low cost automation
analysis of cycle time study of one process required 70sec.
Production quantity in numbers at 95% line efficiency at this
stage was 708 units per day.

19.  At the stage of after implementation of low cost automation analysis of
cycle time study of one process required 66sec.
 Production quantity in numbers at 95% line efficiency at the stage of after
implementation is produce 775 units per day.
Fig. LCA implementation for optimization of cycle time

20. CONCLUSIONS
 As in this case study the main basic theme was to improve the
productivity through elimination non-value added activity in
transmission line.
 This was obtained by implementing LCA.the productivity was
increased from 706 to 770 units/day. the cost of operation is
reduced considerably
