Description

Rotor and damper plate transfer device of V-Cal motor

The present invention relates to a device for automatically transferring the rotor and the damper plate of the motor on the head drum when assembling the head drum of the BC-AL. More specifically, the damper is located on the upper side of the rotor. It relates to a rotor and a damper plate transfer device of the motor for V-Cal which is capable of firmly fixing the plate and preventing falling of the damper plate to achieve stable operation to improve work productivity.

In general, a VCR (Video Cassette Recorder) is a kind of A / V device, and a video system is driven by driving a deck system and a video tape with the driving system. It is a device composed of video, voice recording, and playback system that can record audio tracks and video tracks, or vice versa.

The drum assembly mounted on the V-C is an upper drum rotatable at high speed by a drum motor for image tracking of the tape, a lower drum connected to a shaft passing through the center thereof, and an outer peripheral surface of the upper drum. To protrude, it is composed of a plurality of heads (two for two-head BC, four for four-head BC) mounted on the bottom of the upper drum.

On the other hand, in order to install the drum assembly on the tech plate inclined at a predetermined angle, it is necessary to mount a component such as a stator or a rotor constituting the drum motor as a plurality of screws on the lower side of the lower drum. Such a motor is fixed to the drum base, and the assembling work of the drum base is performed as a screw automatic fastening device.

In this regard, FIG. 6 shows a rotor and a damper plate transfer device 100 of a conventional BC motor.

The conventional rotor and damper plate transfer device 100 is a vertical pillar 112 is located on one side of the bottom surface on which the head drum seating jig 105 and the rotor support 110 is located, the vertical pillar 112 At one end of the crosspiece 115 is rotatably mounted at the upper end of the crossbar, and a guide rail 117 is formed at one side of the crossbar 115 so that the slide cylinder 120 is mounted on the slide cylinder. One side of the 120 is the pneumatic cylinder 122 is mounted downward. In addition, the lower end of the rod 122a of the pneumatic cylinder 122 has a configuration in which the clamp jaw 130 is opened and closed by pneumatic pressure.

The conventional rotor and damper plate transfer device 100 is a clamp jaw 130 is opened, lowered to the upper side of the rotor pedestal 110 by the pneumatic cylinder 122, between the clamp jaw 130 The rotor 132 is picked up and lifted from the rotor support 110, and the clamp jaw 130 and the rotor 132 are moved to the head drum 140 by the operation of the slide cylinder 120 to move the head drum. It will be put on the top of 140. However, in this operation, a thin plate called a damper plate 135 is positioned on the upper side of the rotor 132, and the damper plate 135 is placed on the upper surface of the rotor 132, and then the rotor ( When the 132 is fixed to the head drum 140, it is to be fixed integrally to reduce the frictional resistance of the rotor 132, such damper plate 135 is a conventional clamp jaw 130 is a rotor Since only 132 is fixed and conveyed, even if a small impact is applied from the outside during the movement of the rotor 132, it is easily dropped from the upper surface of the rotor 132 and falls. Therefore, the operator picks up the damper plate 135 and manually places the damper plate 135 and the rotor 132 on the top of the rotor 132 on the head drum 140 again by screwing the head drum at the same time. It is fixed to 140.

Therefore, the conventional rotor and damper plate transfer device 100 has a problem that the work is very cumbersome and deteriorates the work productivity by dropping the damper plate 135 when the rotor 132 falls during the movement of the rotor 132. Was.

In addition, the conventional rotor transfer device 100 to the head drum 140 because the clamp jaw 130 only puts the rotor 132 and the damper plate 135 on the upper side of the head drum 140. There is also a problem that a poor product occurs due to the failure to achieve a complete coupling during the screwing operation of the rotor 132 and the damper plate 135 due to not being in close contact.

The present invention has been proposed in order to solve the above problems, it is possible to firmly fix the damper plate located on the rotor and the upper side and to prevent the fall of the damper plate to achieve a stable operation to improve the work productivity, head drum It is an object of the present invention to provide a rotor and a damper plate transfer device for a V-Cal motor which is improved to allow stable screwing by bringing the rotor and the damper plate into close contact with each other.
