Description

Technical Field

[0001] The invention relates to the technical field of film coating, in particular to a film coating rotating rack. Background Art

[0002] At present, when using vacuum coating equipment to coat multiple products at the same time, a rotating rack is generally set in the process chamber of the equipment, and the products are fixed on the rotating rack by hanging rods, so that the products are coated while following the rotation of the rotating rack. Through the rotation of the rotating rack, each product on the rotating rack can get an equal opportunity to be coated facing the sputtering target.

[0003] For example, a coating rotating rack with the invention patent publication number CN114774876A limits the self-rotation of the hanging rod by forming a lateral resistance to the two cranks through the arc track segment. When the hanging rod revolves to guide a crank located at the front side to the turning track segment, the front and rear positions of the two cranks are interchanged by utilizing the deflection effect of the swing arm, thereby driving the hanging rod to perform a self-rotation action, realizing periodic rapid flipping of the product installed on the hanging rod, so as to improve the deposition rate and film uniformity.

[0004] But it still has some shortcomings:

[0005] During the coating process, due to the traditional gear meshing rotation, it is easy to cause jamming and blocking, which affects the coating efficiency during the rotation and use;

[0042] Through the above design, in conjunction with the output end of the motor 2, the supporting disc 3 can drive the rotating support rod 9 and the anti-fouling cover 22 to rotate stably at the top of the fixed base 1. At the same time, under the rolling action of the first ball 6 and the second ball 47, the smoothness of the rotation of the supporting disc 3 at the top of the fixed base 1 is effectively improved, and the occurrence of poor coating effect caused by jamming is effectively reduced.

[0043] The mounting mechanism includes an abutment and limiting plate 25 annularly mounted on the bottom end of the inner wall of the anti-fouling cover 22, mounting side plates 28 are fixedly mounted on both sides of the bottom end of the abutment and limiting plate 25, the middle part of the mounting side plate 28 is connected to the outer wall of the connecting port 30 by a second bolt 29, a sealing plug 26 is fixedly mounted on the middle part of the bottom end of the abutment and limiting plate 25, and a connecting pipe port 27 is installed on the middle part of the bottom end of the sealing plug 26, the connecting pipe port 27 is inserted at the top end of the connecting port 30, and the bottom end of the connecting port 30 is fixedly mounted on the middle part of the outer wall of the spray block 31.

At this time, after the columnar workpiece is placed vertically, the abutting top block 14 is released, so that the bottom end of the abutting pad 15 can be directly abutted against the top of the columnar workpiece under the action of the elastic reaction force of the first spring 12 and the second spring 18, and the limiting work of the columnar workpiece can be completed at this time;

[0048] When the bearing disc 3 rotates at the top of the fixed base 1 under the action of the top output end of the motor 2, the bearing disc 3 can move smoothly at the top of the fixed base 1 relatively conveniently under the rolling action of the first ball 6 and the second ball 47;

[0049] By pulling the connecting top plate 34 downward to release the negative pressure state of the top end of the sealing plug 26 from the bottom end of the connecting side plate 10, the cleaning shell 32 is held at this time, so that the cleaning cotton block 41 on the inner side of the cleaning inner plate 40 is driven to clean the outer wall of the rotating support rod 9 under the joint action of the hinged support of the first hinged rod 37 and the third spring 39 and the elastic potential energy of the second hinged rod 38.
