Benefits of Pick and Place Servo Drives

 In an age of rapid industrialization and intense competition, manufacturers simply cannot afford to compromise on the speed and accuracy of the machines and assembly lines in their production units. Prudence thus lies in investing in servo systems that speed up the functions on the assembly line front and also add to the precision of the operations. Herein stems the importance of pick and place robots in an assembly process. These systems are commonly found in industrial automation processes and are used to sort components and place them in their appropriate slots in the line.

Pick and place servo drives systems are some of the most expensive components in an industrial assembly line but manufacturers usually do not hesitate to invest in these because of the advantages that installing one such system affords. The following are some of the benefits of pick and place systems:

• Speed: Pick and place robotic systems, by automating processes, speed up cycle times. This in turn, leads to faster production, a key requirement for businesses to prosper in a 24X7 world. A servo controlled pick and place system is especially considered matchless on this front.

• Precision: Pick and place systems are almost 100% accurate in their operations, much more than a human being can ever be. When quality is the key to retaining customers, this feature ensures that manufacturing units engaging pick and place systems are consistently able to outsmart competition.

• Reliability: Powered by servo control, pick and place systems, when in top-notch shape, can work round the clock on all days of the week. This enables a manufacturing unit to churn out products in almost no time at all. This in turn, leads to considerable revenues.

• Flexibility: A slight tweak in the programming controls or a few twists and turns of the tools are all that is needed to equip a pick and place system with the capability to deal with multiple applications. This flexibility makes installing such a system extremely cost-effective.

• Cost-Effectiveness: The afore-mentioned features combine to lend a high degree of cost-effectiveness to such systems. Cost effectiveness also accrues from the fact that pick and place systems empower businesses to take up orders in bulk and thus aid business expansion and also reap the benefits of large-scale production.

Advances in technology in recent times complemented by a drop in prices, have made pick and place systems more affordable. It is thus possible for even small-scale production unit owners to own such a servo control system and reap its benefits.

Servo Amplifier

A servo amplifier is a part of the closed loop servo control drive system is designed to primarily control the performance of a mechanism. Basically they are four-quadrant, power amplifiers with regenerative features and equipped to supply power according to the control voltage to the overall motor. These servo amplifiers can supply energy to the load, as well as absorb energy from the load. They are also designed to convert the kinetic energy of the combined motor load into electrical energy while the load is decelerating.

The output of a servo amplifier is an analogue circuit. The circuit enables the current and voltage of the motor to be adjusted to control position, torque and velocity. The feedback and comparator stages though can have a mixture of analog and digital devices.

Few ideal characteristics that are desired in a servo amplifier are as follows:

• Constant Velocity – ability to maintain the commanded velocity. Tachometers are used to record the aberrations between the commanded and actual motor speed.

·         Infinite Acceleration – an ideal amplifier must be able to provide infinite acceleration which can be observed by abruptly starting and stopping the motor.

·         Linear response – the amplifier need to respond proportionally to the changes in the velocity input command.

·         Hold Position – the amplifier should drive the motor in such a way that the latter holds its position irrespective of any external force or disturbance.

·         Overload protection – a low resistance circuit should be there to protect the amplifier from excessive current.

There are a host of servo amplifiers in the market but one should be careful while choosing an amplifier. The compatibility of the servo amplifier with its servo is to be ensured. Some notable types of servo amplifiers are as follows:

• Push Pull amplifiers – one of the earliest designs of amplifiers designed primarily for two transistors to get switched on/off to share the current load for the motor.
• Chopper amplifier – another primitive DC-motor based amplifier that finds limited usage today.
• L Type (Linear Motion) Servo Amplifier – it is fitted with linear positioning function you can basically construct a linear positioning system using such amplifiers as a ball screw or rack & pinion.
• Digital Amplifier – it is usually used for higher machine performance as it promises improved reliability and repeatability through digital technology.
• R Type (Rotation) Servo Amplifier – it provides an additional rotation angle indexing function. Rotation angle index system can be constructed using this amplifier.
• DC servo amplifier – both brush and brushless amplifiers can be found in simple DC motors

Important Facts behind Servo Motion Controller

Servo drives have been an integral part of efficient output ever since they came into being. The servo motion controller has further enhanced the way industries can work, with precision management of position, velocity and movement and therefore aligning the entire process uniformly. 

The key industries benefiting from servo control system include:

• Assembly line units
• Industrial Machines
• Packaging industries
• Semiconductor production facilities
• Textile mills
• Printing houses
• High end video game industries
• Robot manufacturing
• Medical Equipments

The various servo drive products range from the simple servo motors, DC motors, servo drives, gears, linear motion components and actuators, linear ball and lead screws, linear and rotary brushless servo motors among others. The servo motion controller enhances velocity and position of these machines and their electric motors for effective and efficient output. 

The wires in servo motion control:  The 3 wire connector –

1. One supplies five to six volts of positive charge (DC)
2. The second one serves as voltage ground
3. The third wire acts as the signal wire through which the receiver responds

Servo motion controller not only enhances machine performance but also anticipates mishaps. The in-built mechanism can read slightest of the errors thus acting as a checkpoint for your machine’s efficiency. 

Benefits of servo motion control –

•             Accelerate system development

•             Increase system bandwidth

•             Reduce steady-state errors

•             Diminish loading parameters sensitivity

•             Decrease voltage fluctuations.

•             True asset utilization

•             Lower total production costs

The most commonly referred role of the servo drive is that of the mediator. The control system sends specific signals to the drive which they amplify from their end. Then they transmit the current to the motor to create and incite a motion and torque that is in sync with the original signal, thereby brining in a balance of power and output in the device. This improves performance by adjusting and anticipating change. 

The key functions of the servo motion controller include command tracking and addressing all disturbance rejection traits that lie in the system. Together they track, mange and streamline processes. It includes the drive or the amplifier, motion controller, sensors for tracking feedback along with a hydraulic pump or air cylinder acting as a linear actuator.
