A fixed gear 70 is fixedly installed at one front side of the front flange 20, and a magnetic gear 80 is connected to one end of each jig assembly 40 fitted into the hole of the front flange 20.

At this time, the teeth of the fixed gear 70 and the teeth of the magnetic gear 80 are installed to mesh with each other.

Since the magnetic gear 70 is connected to one end of the jig assembly 40, the jig assembly 40 also rotates when the magnetic gear 80 is rotated.

The drive transmission 60 is formed by a shaft 61 and a pair of guide rollers 62 and 62 ', both ends of which extend over the front and rear flanges 20 and 20'. And a pair of guide rollers 62 and 62 'are positioned to be in contact with the outer circumferential surfaces of the front and rear flanges 20 and 20' to couple to the shaft 61, respectively.

The drive unit 50 is provided with at least one gear between the drive motor 51, the drive motor 51 and the shaft 61, the gear is rotated by the operation of the drive motor 51 and the interlocked with the gear The shaft 61 is also to be rotated.

Here, as shown in FIG. 2, the first gear 52 is installed at the shaft end of the driving motor 51, and the second gear 53 and the third gear 54 meshed with the first gear 52 are driven to the driving shaft ( 55 and the third gear 54 is inserted into the shaft 61, the drive gear 63 and the gear teeth (결합) is installed to be engaged with each other.

The jig assembly 40 is a rod-shaped jig fixture 41 and a plurality of jig 30 is formed in a longitudinal direction in the radial direction of the jig fixture 41, the jig fixture 41 has an axis The screw engaging holes 42 are formed at predetermined intervals in all directions along the axis.

The jig 30 is coupled to and fixed by the screw coupling hole 42.

The jig holder 41 is detachable from the front and rear flanges 20 and 20 ', and when the coating operation is completed on the surface of the mobile phone outer case supported by the jig 30 in the chamber 10, the jig holder 41 is completed. ) Can be removed from the front and rear flanges 20, 20 'and dried on another rack.

The jig 30 is coupled to a support 31 having coupling holes at both sides, a mobile phone outer case fixing plate 32 coupled to the other end coupling hole of the support 31, and a coupling hole at one end of the support 31. It is formed of a jig coupler (33) coupled to the jig holder 41 by a screw coupling hole (42).

The support 31 connected to the mobile phone outer case fixing plate 32 in the jig 30, the jig coupler 33 is a plate spring 34 of the state opened in one direction at one end so that attachment or detachment from the jig fixing stand 41 is easy. You can also install

The leaf spring 34 is not limited to three directions but may be opened in one or more directions.

The leaf spring 34 is installed to open in the opposite direction of the coupling hole of the support (31) Easily detachable from the support (31).

Meanwhile, six bearings 90 are installed at predetermined intervals along the circumferential direction with an axis line as the axis between the fixed gear 70 and the front flange 20 so that the bearings are opened by the periphery of the front flange 20. 90) Wrap it up to be supported.

According to the present invention configured as described above, a jig assembly 40 having a plurality of jigs 30 supported by a mobile phone outer case is coupled, and front and rear flanges 20 and 20 'coupled to both ends of the jig assembly 40. Describe the actions of

As shown in FIG. 2, the first gear 52 coupled to the shaft of the drive motor 51 is rotated by the operation of the drive motor 51, and the second gear 53 and the first gear 53 coupled to the drive shaft 55 are rotated. The three gears 54 rotate in conjunction with each other, and the third gear 54 rotates to rotate the drive gear 63 inserted into the shaft 61 of the drive transmission unit 60.

As the drive gear 63 is rotated, the shaft 61 is also rotated along the outer peripheral surface of the guide rollers 62 and 62 'while the guide rollers 62 and 62' installed at both ends of the shaft 61 are also rotated. The driving force is transmitted to the front and rear flanges 20 and 20 'to rotate the front and rear flanges 20 and 20'.

The front and rear flanges 20 and 20 'are supported in contact with the guide rollers 62 and 62' at the bottom thereof, and the ring-shaped front flange 20 has the periphery of the opening at the fixed gear 70 and the front flange. It is supported by six bearings 90 provided between the 20 and rotates stably.

At this time, the magnetic gear 80 connected to the end of the jig assembly 40 also rotates along the same direction while the front and rear flanges 20 and 20 'rotate. The magnetic gear 80 is fixed gear 70 and Since the teeth are engaged with each other and the magnetic gear 80 is smaller than the fixed gear 70, the front and rear flanges 20 and 20 ′ rotate faster than the speed at which they rotate.

Therefore, as the magnetic gear 80 rotates, the jig assembly 40 also rotates faster than the speed at which the front and rear flanges 20 and 20 'rotate.

When coating by vacuum deposition in the chamber in the above operating state, the coating nozzle is sprayed at an angle toward a predetermined position, but the front and rear flanges 20, 20 'and the plurality of jig assemblies 40 also rotate together. While not only the front side of the mobile phone outer case supported by the jig but also the side facing the injection nozzle for a predetermined time can be evenly coated with a uniform thickness.

In addition, by installing a lot of jig holder 41, which is a combination of a number of jigs 30, the mobile phone outer case is supported on the front and rear flanges (20, 20 ') in the chamber 10, productivity due to coating work within the same time You can also improve.

Meanwhile, after the coating operation is finished, the jig holder 41 is separated from the front and rear flanges 20 and 20 'to dry the coated cell phone outer case at another place, and the cell phone outer case uncoated to another jig holder. Jig is supported in advance by mounting the front and rear flanges (20, 20 ') by making the continuity of the coating work makes a significant contribution to improving productivity.

In addition, the other end of the jig coupler 33 coupled to the screw coupling hole 42 of the jig holder 41 is provided with a leaf spring 34 is inserted into the hole of the support 31 to support the support 31 It can be easily detached from the jig of other products can be easily replaced by coating work.

Embodiment of the coating apparatus of the mobile phone outer case according to the present invention described above is for explaining the spirit of the present invention, the present invention is not limited to the embodiment described above.

Those skilled in the art may be modified in various forms in addition to the embodiments described above, it will be possible to modify the coating apparatus of the mobile phone outer case according to the present invention without departing from the appended claims.
