Abstract: An RFID antenna has a flexible single-sided substrate including a first end, a second end and a leading-out terminal. A plurality of parallel conductors are provided on the substrate and extend between the first end and the second end of the substrate. One of the multiple conductors is broken at the leading-out terminal and extends to an end of the leading-out terminal to form a connection terminal. A flexible covering layer is attached to the substrate and covers the conductors. Ends of the conductors on the first end of the substrate are respectively connected to ends of the conductors on the second end of the substrate to form a helical RFID coil.

Abstract: A small hole electric discharge machining equipment automatic electrode change device having an electrode docking turntable having a plurality of mounting slots located at equal intervals, each with a magnet, holding an electrode chuck. When changing a used electrode chuck on the quick-release collet is required, a first cylinder moves the electrode docking turntable forward and the mounting slot receives the used electrode chuck, which is attracted to one magnet. The quick-release collet then releases the used electrode chuck. The machining rotatory spindle automatically rises and the electrode docking turntable returns to an original position. The electrode docking turntable rotates and positions a new electrode chuck below the quick-release collet. The electrode machining rotatory spindle then lowers attaching the electrode chuck to the quick-release collet, following which the electrode docking turntable returns to the original position, removing the electrode chuck from the mounting slot.

Abstract: A small hole electric discharge machining equipment automatic electrode change device in which the electrode docking turntable has a plurality of mounting slots that are circularly disposed at equal intervals apart, with a magnet situated at each mounting slot, thereby holding each electrode chuck in the mounting slots which are at the same time is attracted to a magnet for firm positioning. When the change of the electrode chuck on the quick-release collet is required, a first cylinder forwards the electrode docking turntable and the mounting slot receives the change electrode chuck, which is at the same attracted to a magnet. The quick-release collet then releases the change electrode chuck, following which the machining rotatory spindle automatically rises and the electrode docking turntable returns to its original position.
