Description

Technical Field

[0001] The present invention relates to the technical field of vacuum coating, in particular to a vacuum coating mounting structure and method. Background Art

[0002] Vacuum coating is a method of preparing functional thin films by physical vapor deposition. Its basic principle is that the atoms of the material are separated from the target source under the action of the electromagnetic field in a vacuum chamber and hit the surface of the plated object. It is widely used in the surface treatment of various components, especially for some car light reflectors, automotive decorative parts and some handicrafts, which need to be coated with a protective film to extend the service life of the product.

[0003] In the prior art, cylindrical or annular workpieces are generally hung on a hanger, and then the hanger fixture is fixed as a whole in the furnace chamber of the vacuum coating machine for vacuum coating operations. The traditional hanger hanging method generally places the workpiece horizontally or tilted so that its top surface faces upward, which not only makes it impossible to coat the mounting position, but also makes it easier for dust to accumulate due to the large area of ​​the top surface of the workpiece. In addition, the horizontal placement of the workpiece will cause the dust on the holes on it to settle on the bottom surface of the holes, affecting the quality of the vacuum coating of the workpiece. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a vacuum coating mounting structure and method which can completely avoid ion ash deposition generated during vacuum coating and effectively ensure the quality of vacuum coating.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention to solve the technical problems is:

[0010] Furthermore, the cylindrical workpiece fixed on the rack is subjected to vacuum coating treatment, comprising:

[0013] Furthermore, the distance between two adjacent cylindrical workpieces is 0.5-5 times the thickness of the cylindrical workpiece.

[0014] Furthermore, the vacuum coating process includes:

[0015] placing the cylindrical workpiece fixed on the jig into a vacuum region;

[0016] Filling the vacuum region with reactive gas;

[0017] applying an electric current to the cylindrical workpiece;

[0018] An electric current is applied to the reaction raw materials, so that the reaction raw materials form charged particles that bombard the surface of the cylindrical workpiece and are deposited on the surface of the cylindrical workpiece to form a coating layer.

[0019] Furthermore, a plurality of support rods are evenly arranged on the fixture base, and the plurality of support rods abut against the stepped grooves, holes and bottom surface on the cylindrical workpiece.

[0022] Furthermore, the jig base includes a main body, a mounting cylinder is provided on the top of the main body, and a positioning cylinder is provided on the bottom of the main body. The outer diameter of the positioning cylinder is less than or equal to the inner diameter of the mounting cylinder. When the jig base is stacked on the rotating rod, the positioning cylinder of the main body located above is passed through the mounting cylinder located below.

[0023] Furthermore, the second rod is made of a metal or non-metallic material with a certain degree of elasticity. The cylindrical workpiece is placed on the second rod. Under the action of its gravity, multiple second rods rotate relative to the first rod, so that the free ends of the multiple second rods tension and position the cylindrical workpiece.

[0024] Beneficial effects of the present invention:

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1 As shown, a vacuum coating mounting method includes:

[0030] The rack is arranged in a vacuum coating device, wherein the rack includes a rotating rod, the rotating rod is vertically arranged in the vacuum coating device, a jig is arranged on the rotating rod, and a cylindrical workpiece is arranged on the jig so that the rotating rod passes through the cylindrical workpiece;

[0031] The jig includes a jig base, which is sleeved on a rotating rod. A support rod provided on the jig base supports the cylindrical workpiece so that the through hole on the cylindrical workpiece is arranged in a vertical direction.

[0032] The jig and the cylindrical workpiece are stacked one by one on the rotating rod in sequence, and the cylindrical workpiece fixed on the rack is subjected to vacuum coating treatment.

[0033] The support rod of the present invention supports the cylindrical workpiece so that the through hole on the cylindrical workpiece is arranged in a vertical direction, so that the through hole of the cylindrical workpiece and the through holes on it are all arranged in the up-down direction, which can completely avoid the deposition of ion ash generated during vacuum coating, and effectively avoid the problem that the traditional hanging method of the hanger causes the cylindrical workpiece to be placed horizontally, and its upward top surface area is large and more prone to dust accumulation; at the same time, the dust falling from the horizontally arranged hole will be deposited on the bottom surface of the hole. The vertical arrangement not only reduces the small upward top surface area of ​​the workpiece, but also the ion ash originally deposited on the bottom surface of the hole will pass through the through hole or hole, and will not cause deposition at the hole, thereby effectively ensuring the quality of vacuum coating.

[0034] Furthermore, the cylindrical workpiece fixed on the rack is subjected to vacuum coating treatment, comprising:

[0035] The rotating rod drives the jig and the cylindrical workpiece on the jig to rotate, so as to perform uniform vacuum coating treatment on the inside and outside of the cylindrical workpiece.

[0036] Specifically, the rotating rod drives the jig and the cylindrical workpiece on the jig to rotate, thereby completing the vacuum coating of the cylindrical workpiece at various angles. During the rotation process, the surface of the cylindrical workpiece is flexibly vacuum coated to achieve a uniform vacuum coating effect, with excellent flexibility and high degree of automation.

[0037] Furthermore, the rotating rod rotates intermittently or continuously, causing the fixture and the cylindrical workpiece on the rotating rod to vibrate slightly, so as to shake off the ion dust adhered to the cylindrical workpiece during vacuum coating.

[0038] Specifically, the rotating rod rotates intermittently or continuously, which can be performed before, during and after the vacuum coating process. The early vibration can make the stacked fixture bases more tightly connected, and at the same time make the support rod vibrate to the correct supporting position of the cylindrical workpiece. Slight vibration during the coating process can make the cylindrical workpiece slightly deviate from the point supported by the support rod and expose the point, thereby ensuring vacuum coating of the supporting point, and can also ensure the overall coating effect without vibration. The late vibration can facilitate the demoulding of the support rod and the workpiece, facilitate the removal of the workpiece, and drive the fixture on the rotating rod and the cylindrical workpiece to vibrate slightly, which can make the ion ash originally deposited on the bottom surface of the hole pass through the through hole or hole, and will not cause hole deposition. Vibration can further avoid the deposition of ion ash on the top surface, effectively ensuring the quality of vacuum coating.

[0039] Furthermore, the distance between two adjacent cylindrical workpieces is 0.5-5 times the thickness of the cylindrical workpiece.

[0040] Specifically, the spacing between two adjacent cylindrical workpieces is 0.5-5 times the thickness of the cylindrical workpiece, so that the gap between the two adjacent cylindrical workpieces is convenient for ion ash to pass through the through hole or hole without causing hole deposition, effectively ensuring the quality of vacuum coating, and also facilitating the adjustment of the spacing.

[0041] Furthermore, the vacuum coating process includes:

[0042] placing the cylindrical workpiece fixed on the jig into the vacuum coating chamber;

[0043] Filling the vacuum coating chamber with reactive gas;

[0044] applying an electric current to the cylindrical workpiece;

[0045] An electric current is applied to the reaction raw materials, so that the reaction raw materials form charged particles that bombard the surface of the cylindrical workpiece and are deposited on the surface of the cylindrical workpiece to form a coating layer.

[0046] Specifically, the above-mentioned traditional method is used to coat the cylindrical workpiece. This application does not improve the vacuum coating process. It adopts the above-mentioned existing vacuum coating method. It is set in a vertical direction, which not only reduces the upward top surface area of ​​the workpiece, but also the ion ash originally deposited on the bottom surface of the hole will pass through the through hole or hole, and will not cause hole deposition, effectively ensuring the quality of vacuum coating.

[0047] Furthermore, a plurality of support rods are evenly arranged on the jig base, and the plurality of support rods abut against the stepped grooves, holes and bottom surface on the cylindrical workpiece. Under the action of the gravity of the cylindrical workpiece, the support rods clamp the stepped grooves, holes and bottom surface on the cylindrical workpiece, so as to enable seamless mounting of the cylindrical workpiece.

[0048] Specifically, multiple support rods abut the stepped grooves, holes and bottom surface on the cylindrical workpiece, so that multi-point contact is formed between the cylindrical workpiece and the support rods, and the cylindrical workpiece can be vacuum-coated without a trace. The support rods are used for point support, and the spacing between them is convenient to adjust. The second rod is opened to increase the contact surface with the cylindrical workpiece and the multi-point support, making the support more stable, solving the shortcomings of the existing cylindrical workpiece hanging method. It has a simple structure, strong operability and low cost. Under the action of the gravity of the cylindrical workpiece, the support rods clamp the stepped grooves, holes and bottom surface on the cylindrical workpiece, provide clamping force while clamping the cylindrical workpiece, and complete further positioning of the cylindrical workpiece.

[0049] The present invention also includes a vacuum coating mounting structure, including a hanging rack, the hanging rack including a rotating rod, the rotating rod being vertically arranged in the coating chamber of the vacuum coating equipment, the rotating rod being provided with a jig for placing a cylindrical workpiece, the jig including a jig base, the jig base being provided with a jig hole, the rotating rod being passed through the jig hole, the jig base being provided with a support rod, the support rod being used to support the cylindrical workpiece so that the through hole on the cylindrical workpiece is arranged in a vertical direction.

[0050] The support rod of the present invention supports the cylindrical workpiece so that the through hole on the cylindrical workpiece is arranged in a vertical direction, so that the through hole of the cylindrical workpiece and the through holes on it are all arranged in the up-down direction, which can completely avoid the ion ash deposition generated during vacuum coating. The traditional hanging method causes the cylindrical workpiece to be placed horizontally, and its upward top surface area is large, which is more prone to dust accumulation; at the same time, the dust falling from the horizontally arranged hole will be deposited on the bottom surface of the hole. The vertical arrangement not only reduces the upward top surface area of ​​the workpiece, but also the ion ash originally deposited on the bottom surface of the hole will pass through the through hole or hole, and will not cause hole deposition, thereby effectively ensuring the quality of vacuum coating.

[0051] Furthermore, the support rod includes a first rod and a second rod, the first rod and the second rod are connected in an obtuse angle structure, the first rod is arranged on the side of the jig base, and the free end of the second rod abuts against the stepped groove, hole and bottom surface on the cylindrical workpiece.

[0052] Specifically, the free end of the second rod abuts against the stepped groove, hole and bottom surface on the cylindrical workpiece, so that multi-point contact is formed between the cylindrical workpiece and the second rod, and the cylindrical workpiece can be vacuum-coated without a trace. The second rod is used for point support, and the spacing between them is easy to adjust. By opening the second rod, the contact surface with the cylindrical workpiece and the multi-point support are increased, making the support more stable, solving the shortcomings of the existing cylindrical workpiece hanging method, and having a simple structure, strong operability and low cost.

[0053] Furthermore, the jig base includes a main body, a mounting cylinder is provided on the top of the main body, and a positioning cylinder is provided on the bottom of the main body. The outer diameter of the positioning cylinder is less than or equal to the inner diameter of the mounting cylinder. When the jig base is stacked on the rotating rod, the positioning cylinder of the main body located above is passed through the mounting cylinder located below.

[0054] Specifically, another jig base is placed on the rotating rod to form a stacking structure. At this time, the positioning cylinder of the main body located above is passed through the installation cylinder located below, which can ensure the stability of the stacked workpieces. Only the two need to be spliced ​​together to quickly complete the stacking of cylindrical workpieces, saving manpower and high discharge and stacking efficiency, greatly improving production efficiency.

[0055] Furthermore, the second rod is made of a metal or non-metallic material with a certain degree of elasticity. The cylindrical workpiece is placed on the second rod. Under the action of its gravity, multiple second rods rotate relative to the first rod, so that the free ends of the multiple second rods tension and position the cylindrical workpiece.

[0056] Specifically, under the action of gravity of the cylindrical workpiece, multiple second rods rotate relative to the first rod, so that the free ends of the multiple second rods tension and position the cylindrical workpiece, thereby expanding the second rods to change the support range formed by the second rods. It is suitable for coating treatment of cylindrical workpieces of various specifications, and provides clamping force while clamping the cylindrical workpiece to complete further positioning of the cylindrical workpiece, so that it has higher stability. The cylindrical workpiece is supported by multiple points to determine the correct position of the supported object, is not prone to rollover, can have high horizontal accuracy, and achieves better technical effects.

Under the action of gravity, multiple second rods rotate relative to the first rod so that the free ends of multiple second rods tension and position the cylindrical workpiece, and then another jig base is placed on the rotating rod to form a stacked structure. At this time, the positioning cylinder of the main body located above is penetrated on the mounting cylinder located below, and the rotating rod loaded with multiple jigs and corresponding cylindrical workpieces is vertically set in the coating chamber of the vacuum coating equipment for vacuum coating processing.
