Generally, the optical pickup device is installed vertically below a disc, which is an optical recording medium of various optical disc players such as a mini disc player (MDP), a compact disc player (CDP) or a laser disc player (LDP) Detects a desired track position on the disk while moving linearly, detects laser light incident on the pit recorded on the disk surface at the detected track position, detects the reflected light through the optical system, converts the reflected light thus detected into an electric signal And reproduces the recorded contents on the disk surface.

The actuator is an apparatus for finely moving the objective lens for connecting the laser light of the optical pickup device on the disk surface in the radial direction and the optical axis direction to form an accurate focus on the disk surface with laser light.

As shown in FIG. 1, the actuator includes a plate 10 disposed at a lower portion and a bobbin 20 for mounting an objective lens 24 provided on the plate 10. More specifically, As follows.

The plate 10 is provided with a pair of inner yokes 12 provided with bobbins 20 on the upper side and a pair of outer yokes 14 provided with magnets 13 outside the inner yokes 12, And a second yoke 16 is formed on the outer side of one side outer yoke 14 to which the suspension chassis 38 is attached.

The bobbin 20 is provided with a laser passage hole 22 at the center thereof and an objective lens 24 for focusing a focus on the disk reflection surface is bonded above the laser passage hole 22, A focusing coil 26 for moving the objective lens 24 in the direction of the optical axis is wound around the inner yoke 12 while being floated. A pair of tracking coils 28 for moving the objective lens 24 in the radial direction are bonded to both sides of the focusing coil 26, respectively.

The tracking coil 28 and the focusing coil 26 are attached to both sides of the bobbin 20. The focusing coil 26 and the tracking coil 28 are mounted on the coil cover 30, And a suspension wire 34 for supporting the oscillation of the bobbin 20 and attenuating the vibration of the bobbin 20 when the shock is applied from the outside.

The second yoke 16 is provided with a holder gel 36 to which a damping gel 37 is injected. The suspension wire 34 is bonded to the suspension coil 38 via the holder gel 36.

Therefore, when the objective lens 24 adhered to the bobbin 20 vibrates while moving by the focusing coil 26 and the tracking coil 28 to focus on the recording pit on the disk, the bobbin 20 The vibration of the supporting suspension wire 34 is rapidly reduced by the damping gel 37 so that the objective lens 24 can stably focus on the disk.

This damping gel 37 also attenuates vibrations transmitted from the outside to the suspension wire 34 rapidly from the outside even when the disk player with the built-in actuator is installed in a place where vibration of the vehicle or the like is severe, It does not transmit.

Since the damping gel 37 having such an action is in a liquid-like state due to its high fluidity before being cured, the damping gel 37 is injected into the holder gel 36 after the assembly of the actuator is completed and cured in a curing facility where high temperature and low humidity are maintained. To form a gel having a strong viscosity.

In order to inject the damping gel 37 into the holder gel 36, the damping gel 37 is injected into the holder gel 36 by an injector while holding the actuator by hand.

However, such a working method has a problem in that it is difficult to stably fix the small-sized actuator with the hand, and the efficiency of the work is lowered, and the precise work is not performed, thereby increasing the defective manufacturing rate of the actuator.

The assembling process of the damping gel injection jig will be described with reference to FIG.

First, a support table 154 is installed on the base 152 of the support member 150. A length of the installation table 112 of the installation member 110 is calculated in advance, 152). At this time, the fixing method can be performed in an effective manner depending on the material of the supporting member 150 such as bolting or adhesion.

Next, a plate 172 of the actuator 170 and a magnet groove 114 into which the outer yoke 174 formed on the plate 172 can be inserted are formed in the mounting base 112 of the mounting member 110, The magnet 116 is fixed to the magnet groove 114 with an adhesive.

Then, the mounting base 112 is placed between the both side supports 154, and the rotation bar 132 of the rotation member 130 is inserted into the rotation hole 156 of the both side support base 154, And the mounting base 112 is supported on the support base 154 by the rotation bar 132.

Then, the lever 136 is press-fitted into the rotation bar 132 on one side or both sides. At this time, the lever 136 may be coupled to the rotation bar 132 by a method such as adhesion in addition to press fitting. The plate spring 138 is mounted on the support base 154 with the bolts 140 so as to be in contact with the gear teeth of the lever 136.

Then, the handle 134 of the rotating means is press-fitted into the rotation bar 132 on one side or both sides.

Even if the lever 136 and the fitting holes 135 and 137 of the handle 134 and the rotating bar 132 are formed in a polygonal shape and in particular a quadrangular shape so that the pressing force is weak, It will not turn.

The lever 136 and the handle 134 are first engaged with the rotation bar 132 and the support stand 154 is inserted between the lever 136 and the handle 134 according to the method of assembly operation, The installed rotation bar 132 may be inserted into the rotation hole 156 of the support base 154 and screwed to the screw hole 118 of the mounting base 112. [

The operation of injecting the damping gel into the holder gel 176 using the damping gel injection jig thus assembled is as follows.

The handle 134 is rotated so that the magnet groove 114 formed on the mounting base 112 faces the side and the plate 172 is inserted into the magnet groove 114 with the holder gel 176 of the actuator 170 outside do. Then, the plate 172 and the outer yoke 174 formed thereon are inserted together into the magnet groove 114 and bonded by the magnetic force of the magnet 116.

Therefore, Is installed on the mounting table 112, At this time, a plurality of actuators 170 may be installed according to the number of the magnet grooves 114 formed in the mounting base 112.

This condition is such that the inlet of the holder gel 176 faces sideways making it difficult to inject the damping gel. Thus, by turning the knob 134, the mounting table 112 is rotated to move the actuator 170 installed thereon downward so that the inlet of the holder gel 176 faces upward. At this time, since the rotation of the lever 136 provided on the rotation bar 132 is elastically braked by the leaf spring 138 provided on the support base 154, the mounting base 112 is rotated only when the handle 134 is rotated, The mounting base 112 remains in a stopped state.

In this state, the damping gel is injected into the plurality of holder gels 176 in sequence by the damping gel injector.

When the injection is completed, the injection jig provided with the actuator 170 may be transferred to a hardening facility such as a hardening tank to harden the damping gel. At this time, the injection jig can stabilize the fixed state of the actuator 170, thereby preventing the damping gel injected into the holder gel 176 from overflowing or being hardened while being tilted.

In addition, the actuator 170 is removed from the injection jig by overcoming the magnetic force of the magnet 116, transferred to a separate curing facility to cure the damping gel, and a new actuator 170 is installed in the injection jig. The gel injecting operation may be continued.

As described above, the present invention is an injection jig for rotatably fixing a plurality of actuators 170 for injecting a damping gel into a holder gel 176 of an actuator 170, The damping gel is injected into the actuator 170 installed in the injection jig, and then the damping gel is hardened and cured. In this case, There is an effect that the damping gel can be cured in a good state by fixing the actuator 170 with the injection jig.
