Triple socket outlet / Switzerland
Whether you want to listen to the radio, switch on the shaver or enjoy a cup of freshly made coffee: The sockets that supply these devices with electricity can be found everywhere - like the pictured triple socket outlet from Switzerland. Its inner workings conceal a sophisticated interaction of very different parts: from the metal baseplate through a range of plug contacts and on to the casing.
The solution for the complex production of this assembly consisting of 19 parts is provided by the Bihler BIMERIC BM 3000 servo production and assembly system. This end-to-end system starts by manufacturing the spring clips before then stamping out the baseplates and welding the spring clips to them. The assembly is then inserted in the casing, the intermediate plate is placed in position and the plug contacts, which are produced in parallel, are attached. In this way, 15 ready-to-use triple socket outlets leave the production line every minute.
Connectors for hydraulic valves
Agricultural and construction machines commonly use hydraulic systems to drive their work units. Electrically controlled hydraulic valves ensure that the pressures in these systems are regulated safely and reliably. Three and four-point connectors for hydraulic valves are made on a BIMERIC BM 4500 servo production and assembly system. The contact part is made first. It is punched, stamped and drawn, then a thread is cut.
Next, the connectors are assembled. The BIMERIC BM 4500 inserts a screw, adds the casing, separates the contact part, and then fits out the assembly in a pick-and-place operation. The process is exceptionally reliable because the stamped and bended part is handled directly on the punch strip. Up to 80 connectors a minute in 16 variants can be made on this end-to-end system. Changeovers from one connector type to another are managed by a central control system and can be completed quickly and easily in under 30 minutes.
A perfectly shaped connection
Ring-shaped contact lamella, high current contact
The new ring-shaped contact lamella, which was recently developed for high-current contacts in transformers, switchgear cabinets and circuit breakers, looks almost like a work of art. It consists of a sprung stainless steel carrier strip with riveted lamellar bands and, compared with conventional coils spring contacts, has the advantage of ensuring a constant, low contact resistance coupled with only minimum heating of the contact even when subject to permanent load. And the manufacturing process is every bit as innovative as the component itself.
This can take place particularly quickly and reliable on a BIMERIC BM 3000 servo production and assembly system and a B 20K welding system combined with a Bihler RZV 2.1 radial gripper feed. The output performance runs to an impressive 100 lamellae per minute. During the operation, the system performs all the necessary cutting, bending, stamping and welding steps, as well as the removal of the waste material, in a single, end-to-end process. During the crucial contact welding step, the compact radial gripper feed system ensures the highly dynamic, precise feeding and positioning of the strip material.
Contact at the touch of a button
Whether for a remote control, phone or laptop keyboard: Micro-buttons in the form of so-called short-stroke buttons or keys are a long established part of many manually operated device interfaces. These components, which measure only a few millimeters must ensure extremely reliable switching and provide a sealed contact system in order to establish or break the electrical contact depending on the switch position. A highly efficient solution for the production of pushbuttons at a speed of 240 parts per minute was recently implemented on the BIMERIC BM 3000 servo production and assembly system.
The system takes in the pre-punched strip from the spool, checks the injection molding on the strip by means of a camera and then performs the cutting and bending operations. The part is then fitted from behind with up to three snap washers. The cover is then mounted, again from behind, and a check is performed to ensure correct engagement. The camera inspection and the electrical and mechanical function testing of the pushbutton are then performed. Following laser marking, the OK parts are automatically picked and transported on top the packaging plant. Alongside the high performance it offers, the system excels thanks to the Bihler servo technology, which ensures top quality and the ability to adapt the setup quickly for further switch types.
