Precise and consistent assembly of magnets and coatings with a cobot for the automotive market

LITMAT, a company with over 70 years of experience in supplying components for the automotive industry, has recently introduced the OMRON TM5 cobot within its magnet assembly plant on metal oil drain plugs. The goal of the solution is to simplify the process of assembling the magnets that are necessary to attract any impurities in oil. The cobot takes care of the complete process, from applying the glue, inserting the magnets in the plugs and the verification of the amount of glue applied with the integrated camera. All data is managed centrally by an OMRON NX102 PLC, which can be connected to the MES for integrated supervision of the entire production cycle in real time. At the terminal (OMRON NB Series 7'') the operator can see the information related to processed pieces, types, rejected pieces, causes of stoppage as well as timing, and modify all the parameters relating to the formats if necessary, such as ​​height of the cap, magnet and magnetization. All these variables are supplied to the cobot, which then proceeds with the machining according to the quotas assigned for each different piece to be assembled, without expensive tooling operations. Like all OMRON cobots, even the OMRON TM5 installed in LITMAT can operate in the presence of personnel. Two barriers equipped with a safety module are connected to the PLC and allow the OMRON TM5 to enter collaborative mode. In this way, the employees in charge of sorting the magnets in boxes can work without any risk close to the automated area. Overall, the solution enables LITMAT to assemble approximately 180 caps per hour for a total of 1500 pieces in each 8-hour shift. All with unparalleled consistency: the cobot always exerts the same pressure on the plug, ensuring repeatability and consistent quality. About LITMAT S.p.A.
