ROTOR COIL WINDING DEVICE OF A VIBRATION MOTOR}

The present invention relates to a rotor coil winding device of a vibration motor for winding a coil of a rotor in a vibration motor that notifies reception of a vibration in a communication device such as a mobile phone or a pager, and more particularly, to generate vibration by rotating the rotor. In order to rotate the rotor, a circular coil is mounted around the rotor. Since the coil must be rigid, the coil is formed in three stages. In the first stage, the coil is wound on a hexagonal column at a predetermined number of turns. The coil is wound up, and the wound coil is drawn out as it is in the hexagonal shape. In the second step, the coil formed in step 1 is made into a thin plate, and in the third step, the coil is wound again to make a circular shape, and then the insulation paper is formed in a predetermined size in the center. In the winding machine to form a coil of the rotor by winding the present invention is a process of making a hexagonal coil into a thin plate Bet winding a coil around a hexagonal shape, and relates them to the vibration motor rotor coil winding apparatus for drawing such that its shape is maintained as it is.

Coils used in the rotor of the vibration motor is a three-phase coil for three phases, the length is 9.3mm to 9.7mm, the diameter is composed of 3mm, the form of the step by step for each process of making the coil is It has a form as shown in FIG. Therefore, the coil wound in the first step is weak because the rigidity is to increase the thickness of the flat sheet to make it circular again.

Conventionally, there is a winding machine provided for winding a coil configured as described above, which is a manual step-by-step work process, which is performed by human hands, so that the coil of the rotor is extremely small, which leads to considerable difficulty in the process of going through the process. Falling, there is a variety of problems, such as reduced productivity due to the decrease in productivity.

In particular, since the primary winding, which is a preparatory step for constructing the coil of the rotor, is performed by hand, a change in the shape may be brought about, resulting in a high defect rate in which a part of the wound coil is disconnected.

The present invention has been made in order to solve the above-mentioned conventional problems, and in the rotor coil winding machine of the vibration motor to complete the coil of the rotor in three steps, the coil is wound around the hexagonal pillar at a predetermined number of times in three steps. In the first step of pulling the wound coil in its hexagonal shape as it is, the coil wound in alignment can be taken out without changing the shape, thereby preventing a part of the wound coil from being disconnected and mechanically winding it. The purpose of the invention is to obtain productivity and quality.

In order to achieve the above object, the jig winding the coil is formed in a hexagonal shape to wind a coil supplied from the tension mat, and after the winding, the tab wire twists three coils with hooks, and attaches an adhesive tape to the slide being transferred. The excitation take-out jaw (JAW) is formed so that the coil can be withdrawn from the jig, and the hexagonal coil wound by the high rotor operation of the take-out jaw, which is drawn out and bonded to the adhesive tape, is formed into a thin sheet and then An object of the present invention is to provide a rotor coil winding apparatus for a vibration motor which is transferred to a process.

Hereinafter, the configuration of the present invention in detail with reference to the accompanying drawings as follows.

1 is a schematic diagram of a vibration motor rotor winding machine to which the configuration of the present invention is applied, and shows a three-step process for configuring the rotor coil of the vibration motor. The coil wound by the transfer is made into a thin plate and then transferred to the next process to form a circular coil to bond an insulating material to complete the rotor coil of the vibration motor.

Fig. 2 schematically shows a device of a process of winding a coil supplied from a tension mat to a jig and twisting the coil of the final end of the coil wound by a hook as a configuration of the present invention. It is.

As shown, a jig 10 for winding a coil supplied from a tension mat, a hook 11 for twisting three tab wires after winding a coil in the jig 10, and taking out the wound coil The adhesive tape is formed on the transfer 12 constituting the jaw 13, and the hexagonal coil wound by the high rotor operation of the jaw 13 is constituted by a thin plate. It is a device to transfer to the next process by 12).

Referring to the process of winding the coil by the above configuration is as follows.

The coil supplied through the tension mat is wound on a jig, and the jig is made in a given length in consideration of the length of the coil, and the shape of the jig is wound by a hexagonal coil.

The coil connected after winding on the jig is firstly wound on a hook of a fishing needle driven by a stepping motor and twisted to pull out the tap wire three times. Since the tap wire is three-phase, it is 120 ° It should be made at intervals of. At this time, the operation should be done correctly by the motor.

The coil wound as described above is reduced in shape of the winding jig when the ejection part jaw of the take-out two-transfer is taken out and inserted into the jig while the take-out pin in the middle of the jig is reversed. At this time, the winding coil is attached to the tape attached to the take-out part jaw, and it is reversed to the transfer side.

As such, when the primary winding is completed, the cut coil is pulled out of the coil guide, so the coil gripper presses the coil to prevent separation. When the primary winding coil is attached to the drawer jaw and transferred to the transfer, the coil must be hooked to the winding gripper for the next winding. When the coil guide is fixed to the rim motion rail and descends to the protrusion of the winding gripper, the protrusion The coil is reversed to catch the coil, and the coil gripper reverses to finish the primary winding operation.

The coil formed as described above is deformed into a thin plate shape by the transfer, and the drawout jaw attached to the transformer is retracted while moving forward and backward in the opposite directions by the operation of the high lot. At this time, because the remaining twisted wire after winding must be kept in line, the jaws of the winding part are separated into upper and lower parts. The upper part is already closed when the ejection part draws out the coils to hold the twisted wires, and the lower part is inserted into the winding jig and the primary wound coil is laminated to the next process.

In this way, the coil is wound on the hexagonal pillar a predetermined number of times, and the coil wound up to be aligned in a step 1 operation of drawing the wound coil as it is is pulled out without change of shape to make a thin sheet.

Therefore, according to the present invention as described above, the coil is wound in a hexagonal shape, and the coiled coil is taken out while maintaining the shape thereof and made into a thin sheet, and then sent to the next step, thereby preventing a part of the wound coil from being disconnected. In addition, there is a feature to obtain productivity and quality as it is mechanically cured.
