For the company KENDRION s.r.o. we produced a KYB assembly type machine – E.S. It is a workplace for automated testing of coil assemblies, which is part of the electromagnet used to control the characteristics of the suspension damper.

The device verifies the electrical functionality of the coils, visually inspects the contacts using a camera and marks the plastic parts of the coils with a laser.

Customer requirements

The assignment was to create a single-purpose machine for testing new types of coils for shock absorbers.

Fulfilling the primary requirements meant ensuring the possibility of performing multiple tests at the same time, while maintaining the specified time of one cycle. Another necessary function of the machine is the laser marking of the coils due to the traceability of each piece, including the evaluation of the quality of the unique brand.

Implemented solution

We used the following components in the manufacture of the machine:

• The machine itself is controlled by a PLC – Siemens Simatic S7-1515F-2PN.
• The HMI panel Siemens TP1200 Comfort is used to operate the machine.
• Simple movements and fixation of the coils are realized using pneumatic cylinders.
• The movement of the coils to individual positions (installation, testing, camera inspection, laser marking) is provided by a carousel whose electric motor is controlled by a Siemens G120 CU240E-2 PN-F converter.
• The SPS electronic HA 1800 B/M high-voltage tester is used to test electrical quantities.
• BURSTER Resistomat 2329 is used to measure coil resistance.
• The camera used to check the contact pins is KEYENCE IV2-G150MA.
• The coil marking laser is the KEYENCE MD-X2000A, which has an integrated DMC reader including evaluation logic.

Benefits for the customer

The supplied machine performs fully automated testing and laser marking of each coil without slowing down production.

Unique tags allow traceability and tracing of each manufactured piece along with the detailed result of the test performed.
