[0042] Specifically, the ions of the silver target material 28 bombarded subsequently are deposited on the artificial hip joint to complete the coating, thereby avoiding the occurrence of a silver oxide layer coating on the artificial hip joint caused by the initial sputtering.

[0043] Please see attached Figure 1 -Attached Fig.13In a preferred embodiment, a first vacuum pump 3 and an inert gas pipe 2 are installed on the top of the box body 1, the inert gas pipe 2 is connected to the inert gas tank, an electromagnetic valve is installed on the inert gas pipe 2, a second motor 5 is fixedly installed on the outside of the box body 1, and the output shaft of the second motor 5 is installed at the top center of the turntable 7, a first motor 4 is installed on the top of the box body 1, and the output shaft of the first motor 4 is installed at the top center of the ring 29.

[0044] The working principle of the present invention is as follows: first, the interior of the box 1 is evacuated by the first vacuum pump 3, and then an inert gas is filled into the interior of the box 1. Then, the artificial hip joint is inserted into the corresponding socket 12, and then the second motor 5 is started (rotated 90 degrees each time). The second motor 5 drives the turntable 7 and the feed ring 8 to rotate, and the feed ring 8 and the turntable 7 rotate, driving the components thereon to revolve together. When the first gear 24 and the arc-shaped rack on the toothed disc 27 are in contact and meshing, the first gear 24 will rotate, and the first gear 24 will rotate to drive the first bevel gear 27 to rotate. The wheel 19 rotates, the first bevel gear 19 rotates to drive the second bevel gear 20 to rotate, the second bevel gear 20 rotates to drive the reciprocating screw 18 to rotate, the reciprocating screw 18 rotates to drive the slide plate 17 to move, the slide plate 17 moves to drive the two second movable rods 22 to move, the two second movable rods 22 drive the connecting plate 15 to move downward, the connecting plate 15 moves downward to drive the socket 12 to move downward and the first movable rod 16 to move, the first movable rod 16 moves to drive the sealing plate 10 to move horizontally (closed, will not affect the feeding ring 8 to rotate to the inside of the box body 1);

[0045] When the second motor 5 is started again, the vent hole 21 in the inner cavity 11 is connected to the inside of the hollow disk 6 through the arc-shaped notch 14, and the inner cavity 11 can be evacuated by the second vacuum pump 9. When the first gear 24 is meshed with the corresponding arc-shaped rack on the toothed disk 27 again, it can be seen from the above that the rotation of the first gear 24 will drive the connecting plate 15 and the socket 12 to move upward and open the sealing plate 10, so that the sealing plate 10 no longer blocks the artificial hip joint, and the artificial hip joint can be sputter-coated;

[0046] When sputter coating is required for the artificial hip joint, the ion source 43 is turned on to generate glow discharge, and the first motor 4 is started synchronously to drive the ring 29, the back plate 31 and the target material 28 to rotate. When the ring 29 and the back plate 31 rotate for the first time, the ramp plate 34 will be driven to rotate. Due to the setting of the inclined surface on the notch groove 39, the fixed block 38 moves downward. The downward movement of the fixed block 38 drives the third spring rod 37 and the sleeve plate 35 to move downward and causes the second spring rod 36 to generate tension, so that the telescopic end of the third spring rod 37 and the horizontal edge of the U-shaped plate 33 can be pressed tightly and the third spring rod 37 can generate elastic force. In addition, due to the effect of inertia, the T-block 41 has hysteresis, so that the T-block 41 can slide to the inside of the two T-slots 40 (the notch groove 39 is blocked, so that when the ring 29 rotates, the fixed block 38 does not The first spring rod 32 is moved by the ramp plate 34 and the third spring rod 37 is moved by the ramp plate 34. The elastic force generated by the third spring rod 37 causes the telescopic end of the third spring rod 37 to move downward, and the telescopic end of the third spring rod 37 can further block the U-shaped plate 33, so that the baffle 30 is no longer located under the target material 28, so that the ions of the silver target material 28 bombarded subsequently are deposited on the artificial hip joint to complete the coating, thereby avoiding the occurrence of the silver oxide coating on the artificial hip joint caused by the initial sputtering, thereby improving the coating quality;

[0047] When the coating of the artificial hip joint is completed, the second motor 5 is started again to rotate 90 degrees. As can be seen from the above, when the first gear 24 is meshed with the arc-shaped rack on the corresponding toothed disc 27 again, the socket 12 is moved downward and the sealing plate 10 seals the inner cavity 11;

[0048] Finally, the second motor 5 is started again to rotate 90 degrees, and the first gear 24 and the arc-shaped rack on the corresponding gear plate 27 are meshed, so that the artificial hip joint after coating is moved upward and the sealing plate 10 is opened, and the artificial hip joint after coating is taken out and the artificial hip joint to be coated is placed;

[0049] In summary, the artificial hip joint can be continuously sputter-coated by reciprocating motion, which not only ensures the quality of the coating but also has high coating efficiency.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
