[0038] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] In this embodiment:

[0040] Reference Figure 1 As shown, a preferred embodiment of the present invention is provided.

[0041] The nano coating device of this embodiment includes a base 1, on which a mechanical arm 5 is installed, and the base 1 is located outside the mechanical arm 5 and is sequentially provided with a baffle 3 and a vacuum box 2, and the base 1 is located below the inner side of the baffle 3 and is provided with a drain pipe 11 extending to the outer side of the bottom of the base 1;

[0042] A truss 4 is installed on the baffle 3, and a guide seat 41 is provided on the truss 4. A nozzle 44 and two groups of laser level gauges 43 distributed on both sides of the nozzle 44 are respectively provided on the guide seat 41. The laser level gauge 43 is used to level the upper surface of the meter body, and the nozzle 44 is used to perform sputtering coating operation on the meter body.

[0043] The robot arm 5 includes a turntable 53, on which a tray 51 is flipped through a bracket 52, and two groups of cross-arranged support plates 54 are arranged at the bottom of the tray 51, and two groups of L-shaped slide plates 55 are opened and closed in the support plates 54, and the ends of the slide plates 55 are provided with claws 56 extending to the top of the tray 51, and a clamping frame 562 is installed through the claws 56, and the ends of the four clamping frames 562 are equipped with blocks 564 for clamping and fixing the watch body, and performing azimuth adjustment operations, and a spin coating motor 12 for driving the turntable 53 to rotate is installed at the bottom of the base 1, and a spin coating operation is performed in conjunction with the sputtering coating of the above-mentioned watch body.

[0044] Refer to the attached Figure 2 and 3 As shown, the guide seat 41 is equipped with a control component 42, a liquid supply valve 441 and a guide motor 411. The control component 42 includes a PLC, which is electrically connected to various electrical components through the PLC. The real-time control of various components is achieved through the PLC programming of model S4-400, thereby completing the orientation adjustment of the coating surface and the coating operation;

[0045] Among them, the liquid outlet end of the liquid supply valve 441 is connected to the liquid inlet end of the nozzle 44, and the liquid inlet end of the liquid supply valve 441 is connected to the external liquid supply system of the equipment through a pipeline. After the laser level 43 is used to complete the leveling of the table body upward, the nozzle 44 is used to complete the sputtering coating operation on the surface of the table body.

[0046] Furthermore, guide wheels 412 are provided on both sides of the bottom of the guide seat 41, and the guide wheels 412 act on the upper part of the truss 4. The output shaft of the guide motor 411 is sleeved with a driving gear, and the inner wall of one side of the truss 4 is evenly provided with tooth grooves meshing with the driving gear. Under the drive of the guide motor 411, the guide seat 41 can slide on the truss 4 through the guide wheels 412, so as to improve the efficiency of coating and the sputtering range.

[0047] Refer to the attached Figure 5-6As shown, the middle parts of the two support plates 54 are connected to the lower part of the tray 51 through a rotating shaft, and a swing motor 573 is installed on the tray 51. The output shaft of the swing motor 573 is connected to an inclined rod 57 extending to the lower part of the tray 51. The external thread of the inclined rod 57 is connected to a connecting block 571, and the end of the connecting block 571 and the end of the support plate 54 are connected to an inclined support rod 572 by a rotating shaft. The inclined rod 57 is driven to rotate by the swing motor 573, thereby pushing the connecting block 571 connected to its external thread to transmit outside the inclined rod 57, and then using the inclined support rod 572 to push the support plate 54 to swing along the rotating shaft, so as to adjust the angle between the two groups of support plates 54. The clamping motor 541 and the internal bearing of the support plate 54 are connected to a clamping rod 542 driven by the clamping motor 541, and the surfaces of both ends of the clamping rod 542 are respectively provided with a forward thread and a reverse thread, and the inner sides of the ends of the slides 55 at both ends are provided with thread grooves that mesh with the forward thread and the reverse thread. The clamping motor 541 drives the clamping rod 542 to rotate, thereby pushing the slides 55 at both ends to achieve reverse synchronous transmission, thereby driving the stop block 564 to complete the function of clamping the watch body, and the above-mentioned swing motor 573 drives the two groups of support plates 54 to change their angles, and cooperates with the alternating clamping of the two groups of clamping motors 541 to achieve the switching of the four clamping points of the watch body, so that the axial position of the watch body itself changes.

[0048] Furthermore, in order to adapt to the clamping position of different types of watch bodies, the internal bearing of the claw hand 56 is connected to a lifting adjustment rod 561, and the end of the clamping frame 562 is threadedly connected to the outside of the lifting adjustment rod 561. By rotating the lifting adjustment rod 561, the clamping frame 562 with its threaded connection is driven to rise and fall, so that the stop block 564 can act on positions at different heights on the surface of the watch body.

[0049] Refer to the attached Figure 3 As shown, the end shaft of the clamping frame 562 is connected to a rotating rod 563, and an arc-shaped damping frame 565 is slidably installed inside the end of the rotating rod 563. One side of the stop block 564 is connected to the two ends of the arc-shaped damping frame 565. Two groups of springs are also clamped on the inner side of the end of the rotating rod 563. A protrusion is provided in the middle of the arc-shaped damping frame 565, and the other ends of the two groups of springs respectively abut against the two sides of the protrusion. Under the action of the rotating shaft and the arc-shaped damping frame 565, the stop block 564 can change its own clamping direction and clamping angle through the clamping force to meet the stability requirements of the special-shaped design watch body.

[0050] An eccentric disk 58 is provided at the end of the bracket 52, and magnetic sheets 581 are evenly distributed on the surface of the eccentric disk 58. An armature 511 is provided at the end of the tray 51. By supplying power to the magnetic sheets 581 at different positions, electromagnetic force is generated to adsorb the armature 511, thereby adjusting the offset angle of the tray 51 to ensure that the grooves or surfaces required for sputtering and spin plating of the watch body can always remain upward, thereby improving the coating effect.

[0051] The present application can continuously level the coated surface of the watch body through two groups of laser levels 43 arranged on the guide seat 41, and perform sputtering coating operations on it through a translatable nozzle 44, combined with a robotic arm 5 that can flexibly adjust, flip and rotate, to achieve multi-angle and all-round coating, and can perform spin coating operations, so that the nano-coating can penetrate into the embedded groove through centrifugal force to ensure the integrity and uniformity of the coating. Compared with traditional vacuum coating, the robotic arm 5 simulates manual operation, and there is no need to frequently manually adjust the orientation of the watch body, and can perform all-round coating operations on the watch body in a vacuum coating environment.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
