Description

Technical Field

[0001] This utility model relates to the field of vacuum coating technology, and in particular to a fixture and coating device for coating small-diameter parts with full diameter. Background Technology

[0002] With the development of high-end optical system applications, the precision requirements for optical components are becoming increasingly stringent, especially the requirements for the coating layers of coated products. Optical coating involves depositing one or more layers of material onto the surface of optical elements to alter their optical properties or improve their optical performance. The coating precision of high-end optical components is mainly reflected in aspects such as optical performance, film thickness control precision, film uniformity and flatness, durability, and stability.

[0003] In the coating process of optical components, full-aperture coating of small-diameter parts is an important technical requirement. Taking a small-diameter optical component with a diameter of 2.6mm as an example, the convex surface coating diameter needs to reach 2.6mm, which means that the full-aperture coating of the component needs to be achieved. Due to the characteristics of vacuum evaporation coating process, the film material evaporates from below, so the coated surface needs to be placed downwards. Since it is a full-aperture coating, it is not possible to directly support the part from the bottom surface, but only to fix it using the side.

[0004] Existing methods for preparing full-aperture optical thin films for small-diameter parts mostly employ a process of depositing a blank and then trimming it to a specified diameter. Specifically, a 5mm diameter blank is first deposited, and then trimmed to a finished size of 3mm. While this method is relatively simple, it has significant technical drawbacks: due to the small size of the parts, the trimming process is difficult, especially centering, which can easily lead to part scrap and increased processing costs.

[0005] Furthermore, traditional clamping methods for small-diameter parts primarily employ end-face clamping, meaning the part is held and fixed by clamps at both ends. This clamping method obscures the end faces of the part, preventing coating treatment and hindering the achievement of true full-diameter coating. For smaller diameter parts, the proportion of the end-face area to the total surface area is relatively large, and the lack of end-face coating significantly impacts the overall optical performance and usability of the part. Utility Model Content

[0006] This utility model provides a fixture and coating device for full-diameter coating of small-diameter parts. The fixture can realize full-diameter coating of small-diameter parts, while avoiding the problems of centering difficulties and complex processing in the traditional process of coating first and then trimming.

[0007] In a first aspect, this utility model provides a clamp for full-diameter coating of small-diameter parts, comprising: a first clamping strip, the first surface of which is provided with a placement groove for accommodating the parts, the placement groove having an opening connected to one side along a first direction; a second clamping strip, connected to the first clamping strip via an adjusting member, the second clamping strip being movable relative to the first clamping strip along the first direction; and a clamping assembly, disposed on the second clamping strip, the clamping assembly having a clamping part, the clamping part abutting against the outer peripheral surface of the parts located in the placement groove through the opening.

[0008] In one possible implementation, the clamping assembly includes: a top block with a clamping portion at one end facing the placement groove; and an elastic member, one end of which abuts against the end of the top block away from the clamping portion, and the other end of which abuts against the second retaining strip.

[0009] In one possible implementation, the top clamping part is provided with a first pick-and-place groove, which is connected to the placement groove through an opening; the first surface of the first clip is provided with a second pick-and-place groove that is connected to the placement groove, and the second pick-and-place groove is arranged opposite to the first pick-and-place groove.

[0010] In one possible implementation, the first surface of the first card bar is provided with a first movable groove extending in a first direction, the first movable groove is connected to the placement groove through an opening, and the pressing part of the top block is slidably disposed in the first movable groove.

[0011] In one possible implementation, the depth of the first active tank and the second pick-and-place tank is greater than the depth of the placement tank, for bidirectional discharge of cleaning fluid from the placement tank.

[0012] In one possible implementation, the second card strip is provided with a second movable groove extending in a first direction; the top block is provided with a limiting part at one end away from the tightening part, the limiting part is slidably disposed in the second movable groove, and the elastic member is located in the second movable groove, with one end abutting against the limiting part and the other end abutting against the inner sidewall of the second movable groove.

[0013] In one possible implementation, a cover plate is also included, which is mounted on the second locking strip to seal the second movable slot.

[0014] In one possible implementation, the first card bar is provided with a plurality of placement slots spaced apart along the second direction, and each of the plurality of placement slots has an opening on one side; wherein the first direction and the second direction are perpendicular to each other.

[0016] In one possible implementation, the two ends of the first card strip extend outward from the second card strip to form a mounting part, which is used to connect the cleaning frame and the planetary disk.

Therefore, this utility model can achieve full-diameter coating treatment of small-diameter parts, while avoiding the difficulties in centering and complex processing problems in the traditional process of coating first and then trimming.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] The following is combined Figure 1-7 This utility model describes a clamping fixture for full-diameter coating of small-diameter parts, comprising a first clamping strip 1, a second clamping strip 2, and a clamping assembly 4, wherein: The first surface of the first card strip 1 is provided with a placement groove 11 for accommodating part a, and the placement groove 11 is provided with an opening 12 along one side of the first direction X.

[0030] The second card strip 2 is connected to the first card strip 1 via an adjusting member 3, and the second card strip 2 can move relative to the first card strip 1 along the first direction X.

[0031] The clamping assembly 4 is disposed on the second clip 2. The clamping assembly 4 has a clamping part 41, which can abut against the outer peripheral surface of the part a located in the placement groove 11 through the opening 12.

[0032] In this invention, a placement groove 11 is disposed on the first surface of the first clamping strip 1 to accommodate part a. An opening 12 is provided on one side of the placement groove 11 along the first direction X. The second clamping strip 2 is connected to the first clamping strip 1 via an adjusting member 3 and can move relative to it along the first direction X. A clamping assembly 4 is disposed on the second clamping strip 2 and has a clamping part 41. The clamping part 41 abuts against the outer peripheral surface of part a located in the placement groove 11 through the opening 12, solving the technical problem of full-diameter coating for small-diameter parts a. Specifically, after part a is placed in the placement groove 11, the clamping part 41 abuts against the outer peripheral surface of part a from the side through the opening 12, completely exposing the end face of part a to be coated without being obstructed by the fixture. During the vacuum evaporation coating process, the film material is deposited from bottom to top, completely covering the entire end face of part a, achieving full-diameter coating. Therefore, this invention can achieve full-diameter coating treatment for small-diameter parts a, while avoiding the difficulties in centering and complex processing in the traditional process of coating first and then trimming.

[0033] Specifically, the placement groove 11 provides positioning and support for part a, and the opening 12 serves as a channel for the clamping part 41. When the second clamping strip 2 approaches the first clamping strip 1 along the first direction X, the clamping part 41 of the clamping assembly 4 passes through the opening 12 and applies a clamping force to the outer peripheral surface of part a within the placement groove 11. The adjusting member 3 can adjust the distance between the first clamping strip 1 and the second clamping strip 2 to accommodate clamping requirements for parts a of different diameters. The clamping part 41 has a contact surface adapted to the shape of part a. The placement groove 11 initially positions part a, and then the clamping part 41 abuts against one side of the outer peripheral surface of part a, achieving clamping of part a through the inner wall of the placement groove 11 and the clamping part 41.

[0034] In a specific embodiment, when coating a small diameter shaft part a with a diameter of 2-8mm, after part a is placed in the placement groove 11, the second clamping strip 2 is moved towards the first clamping strip 1 by the adjusting member 3, and the clamping part 41 applies clamping force to the outer peripheral surface of part a from the side. Both end faces of part a are completely exposed and can receive coating treatment from all directions of the end faces to obtain a complete full-diameter coating effect.

[0035] In related technologies, small-diameter parts a are typically clamped using an end-face clamping method, where a clamp is used to hold and fix the part a from both end faces. However, the end faces are obscured by the clamp, preventing coating and resulting in incomplete coating, which affects the performance of part a. In this embodiment, however, a side clamping method is used. The clamping part 41 abuts against the outer circumference of part a from the side through the opening 12, fully exposing the end faces of part a. This solves the coating obstruction problem caused by traditional end-face clamping methods, truly achieving full-diameter coating treatment for small-diameter parts a.

[0036] In some embodiments, the clamping assembly 4 includes: a top block 42, with a clamping portion 41 provided at one end of the top block 42 facing the placement groove 11; and an elastic member 43, with one end of the elastic member 43 abutting against the end of the top block 42 away from the clamping portion 41, and the other end abutting against the second locking strip 2.

[0037] In this utility model, the clamping component 4 includes a top block 42 and an elastic element 43. The top block 42 is provided with a clamping part 41 at one end facing the placement groove 11. One end of the elastic element 43 abuts against the end of the top block 42 away from the clamping part 41, and the other end abuts against the second clamping strip 2. The elastic clamping force provided by the elastic element 43 can ensure the reliability of clamping and avoid rigid compression damage to part a.

[0038] Specifically, the elastic element 43 adopts a spring structure, which has good elastic characteristics and small deformation. When the first locking bar 1 and the second locking bar 2 are separated, the spring is in a relaxed or natural state and will not hinder the insertion of part a. When the second locking bar 2 moves toward the first locking bar 1, the spring is compressed and generates elastic force, which pushes the top block 42 so that the clamping part 41 applies a clamping force to part a.

[0039] In one specific embodiment, part a in the processing batch has a dimensional tolerance of ±0.02mm. The elastic deformation of the spring can automatically adapt to this dimensional difference, providing a suitable clamping force for each part a, ensuring that part a will not deform due to excessive clamping force or loosen due to insufficient clamping force, and that the clamping effect remains consistent during batch processing.

[0040] In some embodiments, the top clamping part 41 is provided with a first pick-up and put-out groove 44, which is connected to the placement groove 11 through the opening 12; the first surface of the first card strip 1 is provided with a second pick-up and put-out groove 13 that is connected to the placement groove 11, and the second pick-up and put-out groove 13 is disposed opposite to the first pick-up and put-out groove 44.

[0041] In this utility model, the top clamping part 41 has a first pick-and-place groove 44 and communicates with the placement groove 11 through the opening 12. The first surface of the first clip 1 is provided with a second pick-and-place groove 13 that communicates with the placement groove 11. The first pick-and-place groove 44 and the second pick-and-place groove 13 are arranged opposite to each other, providing a two-way operation channel for the operator, making the loading and unloading of small diameter parts a more convenient.

[0042] Specifically, the first pick-and-place slot 44 is located at the clamping part 41. When the clamping part 41 is in a non-clamping state, the first pick-and-place slot 44 communicates with the placement slot 11 to form an operating space. The second pick-and-place slot 13 is located on the first surface of the first clamping strip 1 and is directly connected to the placement slot 11. The two pick-and-place slots are arranged opposite to each other, allowing the operator to access part a from two directions.

[0043] In one specific embodiment, for a small-diameter part a with a diameter of 3mm, due to its small size and smooth surface, the operator can easily use tweezers to grip part a from both ends of the first pick-and-place slot 44 and the second pick-and-place slot 13 to complete the pick-and-place operation of part a. The bidirectional operation mode makes the loading of part a more stable and controllable, and it is not easy to fall off when it is taken out, thus significantly improving the operation efficiency.

[0044] In some embodiments, the first surface of the first card strip 1 is provided with a first movable groove 14 extending along the first direction X. The first movable groove 14 is connected to the placement groove 11 through the opening 12, and the pressing part 41 of the top block 42 is slidably disposed in the first movable groove 14.

[0045] In this invention, the first surface of the first locking strip 1 is provided with a first movable groove 14 extending along the first direction X. The first movable groove 14 is connected to the placement groove 11 through an opening 12. The clamping part 41 of the top block 42 is slidably disposed in the first movable groove 14, providing precise guidance for the movement of the clamping part 41, making the clamping action more stable and reliable. Specifically, the first movable groove 14 extends along the first direction X, consistent with the moving direction of the clamping part 41. When the second locking strip 2 moves relative to the first locking strip 1, the clamping part 41 slides in the first movable groove 14. The groove wall of the movable groove guides the clamping part 41, restricting its displacement in other directions.

[0046] In one specific embodiment, during the batch clamping of parts a, the first movable groove 14 ensures that the clamping part 41 can only move along the predetermined first direction X, avoiding the clamping part 41 from shifting or tilting during the clamping process, ensuring the correct contact between the clamping part 41 and the outer peripheral surface of part a, and guaranteeing clamping accuracy and repeatability.

[0047] In some embodiments, the depth of the first active groove 14 and the second pick-and-place groove 13 is greater than the depth of the placement groove 11, for bidirectional discharge of cleaning fluid in the placement groove 11.

[0048] In this invention, the depth of the first movable groove 14 and the second pick-and-place groove 13 is greater than the depth of the placement groove 11, forming an effective liquid discharge system for bidirectional discharge of the cleaning liquid in the placement groove 11, ensuring that the part a and the fixture can be thoroughly dried after the cleaning process, creating favorable conditions for the subsequent coating process.

[0049] Specifically, according to the processing sequence of part a, part a needs to undergo a cleaning process before coating, and the cleaning solution used includes chemical solution or cleaning water. Since the first active tank 14 and the second pick-up and drop-off tank 13 are deeper, they form a lower area relative to the placement tank 11. Under the action of gravity, the cleaning solution flows from the placement tank 11 to these deeper areas and is quickly discharged.

[0050] In one specific embodiment, after part a is cleaned, the cleaning fluid can be quickly discharged through the first movable tank 14 and the second pick-and-place tank 13, avoiding the accumulation of liquid in the placement tank 11. The bidirectional drainage channel makes the discharge of cleaning fluid more thorough, shortens the drying time, and improves the conversion efficiency from the cleaning process to the coating process.

[0051] In some embodiments, the second card strip 2 is provided with a second movable groove 21 extending along the first direction X; the top block 42 is provided with a limiting part 45 at one end away from the tightening part 41, the limiting part 45 is slidably disposed in the second movable groove 21, the elastic member 43 is located in the second movable groove 21, one end abuts against the limiting part 45, and the other end abuts against the inner sidewall of the second movable groove 21.

[0052] In this utility model, a second movable groove 21 extending along the first direction X is provided on the second card strip 2. A limiting part 45 is provided at one end of the top block 42 away from the tightening part 41 and is slidably disposed in the second movable groove 21. An elastic member 43 is located in the second movable groove 21, with one end abutting against the limiting part 45 and the other end abutting against the inner sidewall of the second movable groove 21, forming a complete guiding and supporting system, thereby improving the stability and reliability of the clamping mechanism.

[0053] Specifically, the second movable groove 21 provides a guide for the limiting part 45 of the top block 42, ensuring that the top block 42 can only move along the first direction X. The limiting part 45 slides within the second movable groove 21 and simultaneously serves as a support point for the elastic member 43. The elastic member 43 operates within the enclosed space of the second movable groove 21, with one end abutting against the limiting part 45 to transmit elastic force, and the other end abutting against the groove wall to obtain reaction force support.

[0054] In some embodiments, a cover plate 5 is also included, which is mounted on the second locking strip 2 to cover the second movable groove 21.

[0055] In this invention, the cover plate 5 is mounted on the second retaining strip 2 to seal the second movable groove 21, limiting the position of the top block 42 and the elastic element 43. This prevents the top block 42 and the elastic element 43 from falling off during the cleaning, spraying, and spin-drying processes, ensuring the reliability and stability of the clamp in various cleaning processes. Specifically, the cover plate 5 is fixed to the second retaining strip 2 by bolts or clips, covering the opening 12 of the second movable groove 21. The limiting part 45 of the top block 42 and the elastic element 43 are located inside the second movable groove 21. The presence of the cover plate 5 prevents these components from falling out of the groove and restricts their movement in the direction perpendicular to the first direction X.

[0056] In one specific embodiment, part a needs to undergo cleaning processes such as chemical bath cleaning, spray rinsing, and spin drying before coating. During the chemical bath cleaning process, the liquid generates impact force; during the spray rinsing, the high-pressure water flow generates a large impact on the fixture; and during the spin drying process, the high-speed rotation generates a strong centrifugal force. The limiting function of the cover plate 5 ensures that the top block 42 and the elastic element 43 remain in the correct position throughout these processes, preventing them from falling off or shifting.

[0057] In some embodiments, the first card bar 1 is provided with a plurality of placement slots 11 spaced apart along the second direction Y, and each of the plurality of placement slots 11 has an opening 12 on one side; wherein the first direction X and the second direction Y are perpendicular to each other.

[0058] In this utility model, the first card strip 1 is provided with multiple placement slots 11 at intervals along the second direction Y. Each of the multiple placement slots 11 has an opening 12 on one side. The first direction X and the second direction Y are perpendicular to each other. Multiple parts a can be loaded and processed in batches at the same time, which greatly improves production efficiency and is particularly suitable for the batch coating processing needs of small diameter parts a.

[0059] Specifically, multiple placement slots 11 are arranged along the second direction Y, each slot 11 corresponding to the loading position of a part a. The openings 12 of all placement slots 11 face the same side, facilitating unified clamping by the clamping assembly 4. The vertical layout of the first direction X and the second direction Y optimizes the space utilization of the clamp. During the movement of the second clamping bar 2 along the first direction X, multiple parts a can be clamped synchronously. Moreover, through the elastic element 43, even if there are dimensional deviations among the multiple parts a, the clamping effect of the multiple parts a can be guaranteed. More parts a can be accommodated within the limited clamping size.

[0060] In some embodiments, a chamfered structure 111 is provided at the opening of the placement groove 11.

[0061] In this utility model, a chamfered structure 111 is provided at the opening of the placement groove 11, which eliminates the sharp edges and corners of the groove opening, provides a smooth transition for the insertion and removal of part a, reduces operating resistance, avoids scratches on the surface of part a, protects the surface quality of part a, and improves the flow conditions of the cleaning fluid.

[0062] Specifically, the chamfered structure 111 transforms the right-angled edge of the placement groove 11 into a bevel or arc surface. During the insertion process, part a contacts the chamfered surface and smoothly enters the placement groove 11 through the guiding effect of the chamfer. The chamfer also eliminates the sharp edges of the groove opening, avoiding direct collision between part a and sharp edges.

[0063] In one specific embodiment, for small-diameter parts a with precision plating requirements on their surfaces, the chamfer structure 111 ensures that parts a are not scratched by the sharp edges of the groove during loading and unloading, thus protecting the integrity of the surface of parts a. Simultaneously, the chamfer facilitates the flow of cleaning fluid, reduces cleaning dead zones, and improves the cleaning effect.

[0064] In some embodiments, the two ends of the first clip 1 extend out of the outside of the second clip 2 and form a mounting portion 15, which is used to connect the cleaning frame 6 and the planetary disk 8.

[0065] In this utility model, the two ends of the first card strip 1 extend out of the outer side of the second card strip 2 and form a mounting part 15. The mounting part 15 is used to connect the cleaning frame 6 and the planetary disk 8. The card can be connected to different equipment in a standardized manner. The same card can be adapted to both cleaning equipment and coating equipment, thereby improving the versatility of the equipment and the continuity of the process.

[0066] Specifically, the mounting part 15 serves as a standardized interface for the clamp, and can be fixed to the mounting slot of the cleaning frame 6 with bolts. Then, the mounting part 15 is pressed and fixed by the pressure plate 7, achieving stable installation of the clamp on the cleaning equipment. Similarly, the mounting part 15 can also be connected to the mounting port 81 of the planetary disk 8 via a snap-fit ​​or positioning pin, allowing for rapid loading of the clamp onto the coating equipment. The extension of the mounting part 15 also enhances the overall rigidity of the clamp.

[0067] In one specific embodiment, after part a is clamped, the entire fixture can be directly transferred from the cleaning equipment to the spin-drying equipment, and then to the coating equipment, without the need to reload and unload part a, thus avoiding repetitive operations between processes. The standardized interface of the mounting unit 15 enables quick and convenient conversion of the fixture between different devices, improving the automation level and production efficiency of the production line.

[0068] In related technologies, cleaning and coating processes typically use different fixtures, requiring part a to be reloaded and unloaded between processes, increasing operational steps and time costs, while also posing a risk of part a loss and contamination. However, in this embodiment of the invention, the mounting unit 15 is compatible with the connection between the cleaning frame 6 and the planetary disk 8, allowing the same fixture to be used throughout the entire processing flow. This eliminates repetitive loading and unloading operations between processes, improving process continuity and production efficiency.

[0069] This utility model provides a coating device, including: a planetary disk 8, the planetary disk 8 having a mounting port 81; the aforementioned coating clamps, a plurality of clamps being arranged sequentially along a first direction X at the mounting port 81; and a clamping plate 9, disposed on the planetary disk 8, for clamping one end of the plurality of clamps.

[0070] In this invention, the coating device includes a planetary disk 8 with an installation port 81, and multiple coating clamps are arranged sequentially along the first direction X at the installation port 81. A clamping plate 9 is disposed on the planetary disk 8 to clamp one end of the multiple clamps, thus forming a complete batch coating system. Small-diameter parts a can be coated on a large scale, and the processing capacity and production efficiency of the coating device are greatly improved.

[0071] Specifically, the planetary disk 8, as the core component of the coating equipment, has a mounting port 81 to accommodate multiple clamps. The clamps are arranged sequentially along the first direction X, maximizing the use of the mounting space on the planetary disk 8. The clamping plate 9 secures all clamps through mechanical clamping, ensuring stable positioning of the clamps during the coating process and preventing loosening or displacement. The clamping plate 9 has sliding grooves at both ends, allowing it to slide along the mounting port 81 of the planetary disk 8. After the clamping plate 9 has clamped multiple clamps, fastening bolts can be screwed into the bolt holes on the clamping plate 9 to fix the clamping plate 9 to the planetary disk 8, thus effectively securing the multiple clamps. During coating, the first surface of the first clamp faces upwards, coating the bottom end face of part a.

The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
