To use electric drives instead of pneumatic or hydropneumatic driven cylinders, is a modern advancement in assembly technology. SCHMIDT Technology combined its proven rugged mechanics with the latest electric drive technology to create assembly presses for industrial production applications. The high effi ciency of electric drives may not be the only reason to choose them. The individual process, the infrastructure and the quality of the compressed air should also have a bearing on that decision
The Schmidt Electric Presses is PLC controlled thus eliminating the need for compressed air or hydraulic pressure. This ensures swift integration into existing automated systems.
SCHMIDT assembly machine
On the basis of high-precision SCHMIDT Servo Press modules in the press force range of 0.5 to 100 kN, a assembly machine has been developed, which can be used for fully automated assembly processes in many sectors. The flexible assembly of components with different dimensions in one load becomes reality.

The workstation is equipped with the latest palletised systems for optimum efficiency
The workstation control system can store many data sets for each type of product to be assembled: reducing the need to re-program for each product type.
Freely parameterizable, sequential scanning of the working area
Automatic tool change
Traceability and documentation complying with ISO 9000
Statistic Process Control SPC online
This new development is intended for users who want to create fully automated, highly productive assembly workstations.
Instead of the labourious loading of single parts, workpiece carriers are loaded or unloaded to the machine. This reduces loading time considerably.
The workpiece carrier can contain different components. The Cartesian assembly machine scans the working area sequentially, whereby it is possible to carry out automatic tool changes. A linear table moves the workpiece carrier in X direction. The ServoPress module that presses in Z direction is moved in Y direction via a gantry so that any points in the 3D working area can be accessed via the corresponding profiles.
The flexible data set management of the SCHMIDT Press Control 5000 allows setting up the machines quickly and efficiently. A data set change, for example, if workpiece carriers are loaded with different pieces, can be carried out fully automated from the operating panel. A mechanical retrofitting of the machine is completely avoided.
With regard to intelligent assembly, documentation and Statistic Process Control SPC, the machine disposes of all tools that are provided by the control unit SCHMIDT Press Control 5000.

How to select the right Electro-Mechanical Press
How to select the right electro-mechanical (Servo) Assembly Press
Over the years, press assembly technology has evolved from simple hand-operated presses, which rely on the operator for control, to electro-mechanical presses, which internally control nearly every aspect of the pressing operation. With the advent of the electro-mechanical press (commonly referred to as a servo-press), the level of press control is now virtually unlimited.
Electro-mechanical presses can be grouped into three main categories. They range from a basic servo-actuator, used to generate force, to a highly intelligent servo-press system, which provides force/distance feedback and closed-loop force control. To select the best electro-mechanical press for your assembly operation, you need to understand the important differences between the vari-ous press categories. Then, by comparing the differences in mechanical design and how the system controls and monitors both position and force during the pressing cycle against your specific needs, you will be able to select the right system.
Consisting of a motor and spindle, a basic servo-actuator is generally used to shuttle parts between locations. If properly adapted for pressing, a servo-actuator can be used for uncomplicated press-ing operations. Typically, a servo-actuator offers the user the flexibility to control both the ram position and the ram speed while providing closed-loop position control. A servo-actuator can measure force via the torque of the motor or an externally mounted load cell, but it will not pro-vide true closed-loop force control. Available control packages vary by supplier, system builder and required configuration.
When designed to function as presses, high-end servo-actuators employ several additional me-chanical components including planetary roller screw spindles for higher forces, mechanical clutches, integrated load cells and guided anti-rotational rams. Although software packages, which control and monitor the pressing operation, are available, they do not provide either true closed-loop force control nor rational possibilities to react on blocked actuation. Depending on the sup-plier or builder of the system and required configuration, the unit’s software program will vary greatly in both the degree of press control and the level of monitoring. For joining operations with manual loading these systems are not suitable because of the missing safety devices.
Incorporating all the features of a high-end servo-actuator, a servo-press system contains many additional components that significantly increase the users ability to produce high quality parts. To achieve unsurpassed precision, a servo-press system utilizes totally integrated controls, designed specifically for pressing applications, to monitor the total pressing operation. By incorporating these controls with high-speed data transmission for real-time processing, a servo-press system provides true closed-loop force control and can dynamically compensate for system, tooling and part compression/relaxation.
Designed to operate in an industrial environment, a servo-press system, equipped with an integrat-ed safety circuit, minimizes any electromagnetic interference (EMI) present in the area and incor-porates a lubricating system for maintenance-free operation as well as a motor cooling system which allows a continuous operation under full load. To meet the varying needs of users, the man-ufacturer provides a fully configured control package with standard pressing profiles to accommo-date a variety of pressing requirements. As a result of these unique features, the servo-press system is the most accurate and controlled pressing system available today.
