BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for manufacturing a deflection coil for deflecting an electron beam of an electromagnetic CRT, that is, a deflection coil made of a special shape such as a saddle shape formed to maintain the shape of a coil without a core. In addition, the present invention relates to an air supply device for driving a wire winding guide pin and an air deflecting coil winding device using the air supply device, which lowers and provides an area portion for installing a servomotor on an upper end of a driving spindle of the device.

Various types of deflection coil winding machines have been developed and used to date, and, as an example, the wire rod supplying means supplies an insulated wire coated with a self-adhesive adhesive, and the wires supplied from the wire feeding means are provided. It uses the dedicated mold installed in the spindle unit driven by the servo motor of the motor to make the windings of the saddle-shaped winding body. More specifically, the upper spindles and the lower spindles of the spindle unit, which are installed separately on the same axis, are installed on the same axis. After the pair of upper and lower molds are installed to combine the upper and lower molds, the upper and lower molds are rotated at an appropriate speed, and the wires supplied separately are wound around the combined upper and lower molds and wound into a saddle shape. The winding body is manufactured.

In such winding machines, the spindle unit has a great influence on the characteristics of the deflection coils, where the upper mold of the spindle unit has several guide pins which are at least one necessary for the winding guidance of the wire rod. In order to serve as a variable form of the guide pins are operated by compressed air that is approximately supplied from a separate compressor.

More specifically, the guide pins are freely installed in the upper mold of the spindle unit in the center of rotation, and the guide pins are installed in the upper part of the spindle unit to be mounted and operated according to a preset mode. Compressed air supplied by the supply device is operated in and out of the upper mold. For example, according to a preset mode, the guide pins are sequentially emitted by the compressed air and guide the winding of the wire rod.

However, the air supply device for driving the guide pins of the wire winding is usually installed using the main shaft of the deflection coil winding machine, that is, the area provided at the upper end of the upper spindle unit. The installation of the feeder raises the height of the winding machine, thus increasing the overall volume of the device. In addition, since the air supply device is installed by using the upper end of the main shaft, an expensive hollow servo motor inevitably penetrating the main shaft, for example, a hollow servo motor manufactured by a special type rather than a general motor is inevitably installed. It is a factor that increases the manufacturing cost, the structure of the main shaft is complicated and the situation is inconvenient to replace or repair the main shaft portion.

It is an object of the present invention to achieve an air supply from the side of the spindle by using a bearing stand that supports the upper spindles of the upper spindle unit, thereby lowering the height of the upper spindle unit, thereby reducing the overall volume of the apparatus and miniaturizing the apparatus.
