Technical Field

[0001] This utility model belongs to the field of chemical vapor deposition thin film equipment assembly technology, specifically relating to an auxiliary tool for installing a top cover plate mixing plate. Background Technology

[0002] In the production and maintenance of the SupraD ACHM IV chemical vapor deposition thin film equipment, the gas mixing plate of the top cover plate needs to be installed in two steps: First, the top cover plate is manually lifted to the gas mixing plate placement position, and one of the gas mixing plates, either side A or side B, is installed; after that, the top cover plate is lifted again and rotated 90° or 180° to install the gas mixing plate on the other side.

[0003] It is evident that the traditional installation process requires lifting and moving the heavy top cover plate three times: initial positioning, lifting and rotating, and secondary installation. This is not only inefficient, but the repeated handling can also cause muscle injuries to personnel and risks of equipment collisions. Utility Model Content

[0004] In view of this, the present invention provides an auxiliary tool for installing the top cover plate and the mixing plate, which solves the technical problems of low efficiency and safety hazards associated with manual installation of the top cover plate and the mixing plate.

[0005] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides an auxiliary tool for installing a top cover plate and a mixing plate. This auxiliary tool is used to install the mixing plate and the top cover plate. The tool includes a base plate and fixing members, the number of which corresponds to the number of mixing plates. The fixing members are fixed to the upper surface of the base plate and are matched with the bottom structure of the mixing plate to achieve automatic centering. When the mixing plate is engaged with the fixing members, the top cover plate can be installed above the mixing plate.

[0006] In some embodiments, the fastener is conical, and its conical surface shape matches the conical structure at the bottom of the mixing plate.

[0007] In some embodiments, the bottom of the tapered fastener is provided with a positioning stop, and when the fastener is assembled onto the base plate, the positioning stop ensures that the concentricity error between the fastener and the base plate is less than a threshold.

[0008] In some embodiments, the surface of the base plate is provided with directional marking lines, which are used to indicate the installation direction of the rubber ring of the mixing plate.

[0009] In some embodiments, the direction marking line is a straight line laser-etched on the surface of the base plate.

[0010] In some embodiments, the surface of the base plate is covered with a Teflon coating to reduce the coefficient of friction between the mixing plate and the base plate.

[0011] In some embodiments, the base plate has a first hole and the fastener has a second hole, and there are multiple first holes and second holes, and their positions are distributed in the same way.

[0012] In some embodiments, the first hole and the second hole are engaged by screws to achieve a detachable connection between the base plate and the fastener.

[0013] In some embodiments, the mixing plate has a third hole and the upper cover plate has a fourth hole. There are multiple third holes and fourth holes, and by adjusting the mixing plate, the third hole can be vertically aligned with the fourth hole to fix the mixing plate and the upper cover plate.

[0014] In some embodiments, the base plate is a rectangular steel plate whose dimensions match the projected area of ​​the top cover plate.

[0015] Compared with the prior art, the auxiliary tool for installing the upper cover plate and mixing plate of this utility model has at least the following beneficial effects:

[0016] The auxiliary tool for installing the upper cover plate and the air mixing plate provided by this utility model is used to realize the installation of the air mixing plate and the upper cover plate. The auxiliary tool for installing the upper cover plate and the air mixing plate includes a base plate and fixing components. The number of fixing components corresponds to the number of air mixing plates. The fixing components are fixed to the upper surface of the base plate, and the fixing components match the bottom structure of the air mixing plate to achieve automatic centering. When the air mixing plate is engaged with the fixing components, the upper cover plate can be installed on top of the air mixing plate.

[0017] This invention solves the technical problems in the prior art through the synergistic effect of the base plate and the fixing component: First, the fixing component matches the bottom of the mixing plate with a conical structure. When the two mixing plates are placed on the fixing component, the automatic centering function of the conical surface ensures that the spatial position of the two mixing plates is synchronously and accurately calibrated to match the mounting holes of the top cover plate, completely eliminating the sequential installation limitations caused by the inability to position the mixing plates on both sides in the traditional method. Second, the base plate, as a rigid reference platform, supports the positioned mixing plates. The operator only needs to lift the top cover plate once to cover the mixing plates directly, and tighten the screws directly based on the pre-calibrated hole correspondence, eliminating the step of lifting and rotating the top cover plate a second time after installing one side in the traditional process. This solution reduces the number of times the top cover plate is lifted from three (initial installation, lifting and rotating, and secondary installation) to one, improving efficiency while avoiding the safety risks of repeated handling of heavy components and the hidden dangers of rotation and collision, fundamentally achieving the core breakthrough of "one-time drop, synchronous assembly on both sides".

[0028] This embodiment provides an auxiliary tool for installing the upper cover plate mixing plate, such as... Figs. 1-3 As shown, the upper cover plate 4 air mixing plate installation auxiliary tool is used to install the air mixing plate 1 and the upper cover plate 4; the upper cover plate 4 air mixing plate installation auxiliary tool includes a base plate 2 and a fixing member 3, the number of fixing members 3 corresponds to the number of air mixing plates 1, the fixing member 3 is fixed to the upper surface of the base plate 2, and the fixing member 3 matches the bottom structure of the air mixing plate 1 to achieve automatic centering; when the air mixing plate 1 is engaged with the fixing member 3, the upper cover plate 4 can be installed on top of the air mixing plate 1.

[0029] In this embodiment, the mixing plate 1 is a core functional component of the equipment and needs to be precisely installed to the bottom of the upper cover plate 4; its bottom conical structure is used to cooperate with the fixing component 3 to achieve automatic positioning. The upper cover plate 4 is the cover of the equipment, and it needs to be precisely aligned with the mixing plate 1 during installation, which requires repeated lifting and moving in the traditional process. The base plate 2 provides a stable horizontal reference platform to support the positioning system of the fixing component 3 and the mixing plate 1. The fixing component 3 is a core positioning functional component, which matches the bottom of the mixing plate 1 through its top conical structure to achieve automatic centering of the mixing plate 1.

[0030] The bottom of the mixing plate 1 directly contacts the top of the fixing component 3, forming a positioning fit through tapered geometric matching. The bottom of the fixing component 3 is vertically fixed to the upper surface of the base plate 2 by screws, and the two are rigidly connected. The upper cover plate 4 covers all the mixing plates 1 directly above, and its weight is indirectly transferred to the base plate 2 through the mixing plates 1. The positional relationship of the mixing plate 1, the upper cover plate 4, the base plate 2, and the fixing component 3 from bottom to top is as follows: base plate 2, fixing component 3, mixing plate 1, upper cover plate 4.

[0031] In this embodiment, the fixing member 3 is rigidly connected to the base plate 2 by screws to ensure its vertical fixation; the mixing plate 1 is engaged with the top conical surface of the fixing member 3 through the bottom conical structure, and automatically slides into the center position under the action of gravity to complete the positioning; after all the mixing plates 1 are accurately positioned on the base plate 2 by the fixing member 3, the upper cover plate 4 covers the mixing plate 1 directly above it, and achieves natural alignment installation by relying on the pre-positioning of the mixing plate 1.

[0032] This embodiment solves the technical problems in the background art through the synergistic effect of the base plate 2 and the fixing component 3: First, the fixing component 3 matches the bottom of the mixing plate 1 with a conical structure. When the two mixing plates 1 are placed on the fixing component 3 respectively, the automatic centering function of the conical surface enables the spatial position of the two mixing plates 1 to be synchronously and accurately calibrated to the state consistent with the mounting hole position of the upper cover plate 4, completely eliminating the sequential installation limitation caused by the inability to position the mixing plates 1 on both sides in the traditional method; Second, the base plate 2, as a rigid reference platform, supports the positioned mixing plates 1. The operator only needs to lift the upper cover plate 4 once to cover the mixing plates 1 directly, and tighten the screws directly based on the pre-calibrated hole position correspondence, eliminating the step of lifting and rotating the upper cover plate 4 a second time after installing one side in the traditional process. This solution reduces the number of times the upper cover plate 4 is lifted from three (initial installation, lifting and rotation, and secondary installation) to one time, improving efficiency while avoiding the safety risks of repeated handling of heavy components and the hidden dangers of rotation and collision, fundamentally achieving the core breakthrough of "one-time drop, synchronous assembly on both sides".

[0033] In a specific embodiment, there are two mixing plates 1, and there are also two corresponding fasteners 3.

[0034] In a specific embodiment, the fixing member 3 is conical, and its conical surface shape matches the conical structure at the bottom of the mixing plate 1.

[0035] The fixing member 3 is designed in a conical shape, with its top conical surface perfectly complementing the conical concave (or convex) surface geometry of the bottom of the air mixing plate 1 to be installed. This means that when the air mixing plate 1 is placed on the fixing member 3, its bottom conical structure can naturally and physically conform to the conical surface of the fixing member 3. The core effect of this feature is to achieve automatic centering and precise positioning of the air mixing plate 1. Under the action of gravity, the air mixing plate 1 will automatically slide along the conical surface of the fixing member 3 until its central axis coincides with the central axis of the fixing member 3, thereby ensuring that the air mixing plate 1 is precisely positioned in the preset correct position on the base plate 2. This conical surface matching not only eliminates the need for manual adjustment of the position, but also ensures that the relative positional accuracy between multiple air mixing plates 1 (such as the A / B sides) meets the installation hole requirements of the top cover plate 4, laying the foundation for the subsequent one-time installation of the top cover plate 4. At the same time, the guiding nature of the conical fit makes the placement of the air mixing plate 1 simple and quick, significantly improving installation efficiency and positioning accuracy.

[0036] In a specific embodiment, the bottom of the tapered fastener 3 is provided with a positioning stop. When the fastener 3 is assembled onto the base plate 2, the positioning stop ensures that the concentricity error between the fastener 3 and the base plate 2 is less than a threshold value. This threshold value can be 0.1 mm.

[0037] The locating stop is a stepped coaxial locating structure located at the bottom of the fastener 3, typically consisting of an annular end face perpendicular to the axis and a short cylindrical surface (or conical surface). Specifically, the bottom of the fastener 3 is designed with a raised cylindrical locating step (i.e., the stop), the outer diameter of which fits tightly with the inner diameter of the corresponding mounting hole on the base plate 2. When the fastener 3 is assembled to the base plate 2, the cylindrical step inserts into the mounting hole of the base plate 2, achieving radial constraint through the contact between the side of the step and the hole wall, while the end face of the step fits against the upper surface of the base plate 2 to provide axial limitation. Of course, the locating stop can also be other structures.

[0038] The core function of the positioning stop is to achieve precise alignment and rigid positioning between the fastener 3 and the base plate 2. Its cylindrical stepped structure uses geometric interference to forcibly constrain the radial displacement and angular deflection of the fastener 3 on the base plate 2, ensuring that the central axis of the fastener 3 coincides with the central axis of the pre-set hole on the base plate 2. At the same time, the surface contact between the end face of the stop and the upper surface of the base plate 2 prevents the fastener 3 from tilting after assembly. This design essentially eliminates the assembly gap deviation that may occur during screw tightening, establishing a precise reference coordinate system for the subsequent positioning of the mixing plate 1.

[0039] The concentricity error between the fastener 3 and the base plate 2 directly affects the final positioning accuracy of the mixing plate 1. If the axis of the fastener 3 deviates from the design center of the base plate 2, the position of the mixing plate 1 will shift, making it impossible to align with the threaded hole of the upper cover plate 4. The positioning stop controls the concentricity error through physical hard limiting: its cylindrical step and the mounting hole of the base plate 2 are fitted with a small clearance, and the precision machining of the mating surface ensures that the radial assembly clearance is less than the threshold. When the step is inserted into the mounting hole, the mating surface directly eliminates the radial degree of freedom, forcing the center of the fastener 3 to coincide with the center of the hole of the base plate 2. Even with micron-level machining errors, the stop structure can suppress the concentricity error within the allowable range through the uniform force distribution on the contact surface, thereby ensuring that the mounting hole positions of the mixing plate 1 and the upper cover plate 4 are accurately matched.

[0040] In a specific embodiment, the surface of the base plate 2 is provided with a direction marking line 21, which is used to indicate the installation direction of the rubber ring of the mixing plate 1.

[0041] The core function of the directional marking line 21 is to provide an installation reference for the circumferential angle of the mixing plate 1. Because the rubber ring position of the mixing plate 1 and the air passage interface of the upper cover plate 4 have strict directional matching requirements, if the mixing plate 1 experiences angular displacement in the horizontal plane, it will lead to air passage misalignment or seal failure. The directional marking line 21 is formed by engraving or spraying onto the surface of the base plate 2, creating a straight reference mark aligned with the designed installation orientation of the rubber ring of the mixing plate 1. By aligning the rubber ring position of the mixing plate 1 with this marking line, operators can ensure the consistency of the rotation angle of all mixing plates 1 on the base plate 2, eliminating circumferential installation deviations.

[0042] The directional marking line 21 provides an indication function through visual alignment. During operation, the rubber ring groove (or the center point of the rubber ring) at the bottom of the mixing plate 1 must be rotated to a position that completely coincides with the directional marking line 21. This orientation indication is crucial because: the rubber ring of the mixing plate 1 must precisely cover the gas channel interface of the upper cover plate 4; angular misalignment will cause the rubber ring to misalign with the interface, leading to process gas leakage; the mounting screw holes of the mixing plate 1 and the holes of the upper cover plate 4 are distributed at a specific angle; if the circumferential angle is incorrect, the screws will not be able to be inserted; when two mixing plates 1 are placed on the base plate 2 at the same time, the directional marking line 21 can ensure that the rubber rings of the two are aligned, avoiding the time-consuming adjustment of individual plates.

[0043] In this embodiment, the direction marking line 21 allows operators to quickly complete angle calibration without relying on complex tooling, greatly reducing the risk of rework due to incorrect direction.

[0044] In a specific embodiment, the direction marking line 21 is a straight line mark laser-etched on the surface of the base plate 2.

[0045] The directional marking line 21 is formed into a permanent straight line on the surface of the base plate 2 using a laser etching process. This process uses a high-energy laser beam to precisely ablate the surface material of the base plate 2, creating a physical groove. Its core advantages are: the laser-etched marking has permanent wear-resistant properties, which can withstand the mechanical friction and cleaning agent erosion of repeated placement of the mixing plate 1, avoiding the problem of easy peeling off of traditional ink markings; at the same time, the laser beam can achieve micron-level processing precision, ensuring that the angular deviation between the directional marking line 21 and the axis of the fixing part 3 is small, meeting the orientation accuracy requirements of the rubber ring installation of the mixing plate 1; in addition, the groove structure remains clearly visible after the base plate 2 is coated with Teflon, preventing the marking from becoming ineffective due to coating coverage, and the edge of the groove provides tactile feedback, allowing operators to assist visual alignment by touching it with their fingertips, significantly reducing the error rate of orientation adjustment, and fundamentally ensuring the long-term accurate matching of the rubber ring of the mixing plate 1 and the air passage interface of the upper cover plate 4.

[0046] In a specific embodiment, the surface of the base plate 2 is covered with a Teflon coating to reduce the coefficient of friction between the mixing plate 1 and the base plate 2.

[0047] The Teflon coating covering the surface of the base plate 2 is formed into a low-friction surface layer through a high-temperature sintering process. The core advantage of this design is that it significantly reduces the sliding resistance of the contact surface between the mixing plate 1 and the base plate 2. Specifically, the benefits are as follows: the inherent high lubricity of the Teflon coating allows operators to fine-tune the circumferential angle of the mixing plate 1 with minimal force, ensuring quick and accurate alignment of the rubber ring with the laser-etched direction mark line 21; simultaneously, the non-stick properties of the coating prevent adhesion between the bottom surface of the mixing plate 1 and the base plate 2, eliminating the risk of positioning misalignment caused by surface adsorption; furthermore, the coating is resistant to chemical solvent cleaning during equipment maintenance, maintaining stable low-friction performance over a long period, making the orientation adjustment of the mixing plate 1 always easy and efficient, fundamentally improving the reliability and operational comfort of the installation process.

[0048] In a specific embodiment, the base plate 2 has a first hole 22 and the fixing member 3 has a second hole 31. Both the first hole 22 and the second hole 31 have multiple holes and are located in the same position.

[0049] The array of first holes 22 on the base plate 2 is completely identical to the array of second holes 31 on the fastener 3 in terms of quantity, spacing, and spatial arrangement. For example, when the bottom of the fastener 3 needs to be connected to the base plate 2 by four screws, its second holes 31 are designed as four through holes evenly distributed around the axis of the fastener 3; correspondingly, the four first holes 22 at the corresponding positions on the base plate 2 need to be machined into threaded holes with the same diameter and completely consistent equal division angles (such as 90° intervals). This strict spatial coordinate matching ensures that when the positioning stop of the fastener 3 is inserted into the mounting hole of the base plate 2, the center point of all the second holes 31 can be precisely aligned with the center point of the first holes 22, forming a screw-through channel without deviation.

[0050] During assembly, the positioning stop of the fastener 3 is first inserted into the mounting hole of the base plate 2 to achieve radial positioning. At this time, all the second holes 31 automatically align with the first hole 22. Then, the screws are screwed into the first hole 22 through the second holes 31 in sequence, and the fastener 3 is vertically pressed onto the base plate 2 by the axial tension of the screws. The diameter margin of the second hole 31 can absorb minor machining errors to ensure that the screws can pass through smoothly, while the thread structure of the first hole 22 ultimately achieves rigid locking.

[0051] In a specific embodiment, the first hole 22 and the second hole 31 are engaged by screws to achieve a detachable connection between the base plate 2 and the fixing member 3.

[0052] The core advantage of the detachable connection between the base plate 2 and the fastener 3 achieved by screws through the first hole 22 and the second hole 31 is that the design allows for quick installation or removal of the fastener 3 using standard tools (such as screwdrivers). When the fastener 3 suffers wear on its conical surface or accidental damage due to long-term use, the fastener 3 can be replaced individually by simply loosening the screws without scrapping the entire base plate 2, significantly reducing maintenance costs. At the same time, the detachable structure facilitates disassembly of parts during transportation and storage, reducing the overall size of the tools and avoiding damage from handling. Furthermore, during the initial assembly stage, operators can eliminate the influence of minor flatness errors of the base plate 2 on the perpendicularity of the fastener 3 by fine-tuning the screw tightening sequence, ensuring that the fit accuracy between the conical surface of the fastener 3 and the mixing plate 1 always meets the coaxiality requirements. Moreover, during reassembly after disassembly, the fastener automatically resets itself using the positioning stop, eliminating the need for repeated position calibration.

[0053] In a specific embodiment, the mixing plate 1 has a third hole 11 and the upper cover plate 4 has a fourth hole. There are multiple third holes 11 and fourth holes. By adjusting the mixing plate 1, the third hole 11 can be vertically aligned with the fourth hole to fix the mixing plate 1 and the upper cover plate 4.

[0054] The third hole 11 on the mixing plate 1 is a threaded hole, and the fourth hole on the upper cover plate 4 is a smooth hole. The number and distribution angle of the two are completely consistent. Structurally, when the mixing plate 1 is centered by the conical surface of the fixing member 3 and the circumferential angle is calibrated by the direction mark line 21, the axis of its third hole 11 and the axis of the fourth hole of the upper cover plate 4 automatically coincide. If they do not coincide, the mixing plate 1 can be adjusted to make them coincide. After that, the third hole 11 and the fourth hole form a vertical through channel.

[0055] The operator only needs to screw the screw through the fourth hole and into the third hole 11 to achieve a rigid connection between the mixing plate 1 and the upper cover plate 4. This design ensures uniform force on the connection surface through a distributed multi-hole structure, avoiding deformation of the sealing ring caused by single-point locking. At the same time, the fit tolerance between the threaded hole and the smooth hole allows the mixing plate 1 to slide slightly on the conical surface (assisted by Teflon coating). Even if there is a certain installation deviation, the screw can still be smoothly inserted, greatly reducing the assembly difficulty and making it possible to complete the synchronous locking of the mixing plates 1 on both sides by lifting the upper cover plate 4 at one time.

[0056] In a specific embodiment, the base plate 2 is a rectangular steel plate, the size of which matches the projected area of ​​the upper cover plate 4.

[0057] The base plate 2 adopts a rectangular steel plate structure. Its length and width are designed to cover the maximum outline dimension of the upper cover plate 4 projected on the horizontal plane, ensuring that the edge of the upper cover plate 4 is always within the bearing range of the base plate 2 when it is lowered for installation. The core effect of this size matching is to provide stable support throughout the entire area. When the upper cover plate 4 falls to the top of the mixing plate 1, its weight is transferred to the fixing component 3 through the mixing plate 1, and finally evenly borne by the base plate 2. The rigid structure of the rectangular steel plate can resist the bending deformation caused by the weight of the upper cover plate 4, preventing the mixing plate 1 from being misaligned due to the deformation of the base plate 2. At the same time, the matching projection area allows the operator to place the upper cover plate 4 without precise alignment, and the reserved boundary safety distance avoids tool collision damage, fundamentally ensuring the safety and positioning reliability of the heavy upper cover plate 4 during installation.

[0058] The specific working process of the auxiliary tool for installing the upper cover plate 4 air mixing plate provided in this embodiment is as follows:

[0059] Pre-assembly of auxiliary tools: Align the positioning stop of the fastener 3 with the mounting hole of the base plate 2 and insert it to radially constrain the two; then screw through the second hole 31 of the fastener 3 and screw it into the first hole 22 of the base plate 2 to complete the rigid connection between the fastener 3 and the base plate 2. At this time, the spatial relationship between the conical axis of the fastener 3 and the direction marking line 21 of the base plate 2 has been accurately calibrated.

[0060] Pre-positioning of mixing plates 1: Place two mixing plates 1 on the conical surface of the fixing member 3 respectively, and automatically center them by relying on the conical structure (the bottom conical surface of the mixing plate 1 is in contact with the conical surface of the fixing member 3, and the central axis coincides under the action of gravity); at the same time, rotate the mixing plate 1 so that the center of its rubber ring groove is aligned with the laser etching direction mark line 21 of the base plate 2, and the low friction characteristics of the Teflon coating facilitate fine adjustment of the angle. This step ensures that the spatial position of the third hole 11 (threaded hole) of the mixing plate 1 is consistent with the target hole position of the upper cover plate 4.

[0061] Installation of the upper cover plate 4: The operator lifts the upper cover plate 4 directly above the auxiliary tool and slowly lowers it to cover the two mixing plates 1. At this time: the pre-positioning of the mixing plate 1 automatically aligns the fourth hole of the upper cover plate 4 with the third hole 11 of the mixing plate 1; if there is a deviation, the mixing plate 1 can be slightly slid on the Teflon coating to make the axis of the fourth hole coincide with that of the third hole 11.

[0062] Screw synchronous locking: Screws are passed through the fourth hole of the upper cover plate 4 and screwed into the third hole 11 of the mixing plate 1, and the mixing plates 1 on both sides are tightened simultaneously. The rigid support of the rectangular base plate 2 prevents the upper cover plate 4 from shifting due to gravity, and the boundary safety distance avoids collisions.

[0063] This embodiment provides an auxiliary tool for installing the upper cover plate 4 and the air mixing plate, which achieves the positioning accuracy of the upper cover plate 4 and the air mixing plate. The positioning stop controls the concentricity of the fixing part 3 and the base plate 2, the conical surface fit ensures the positioning accuracy of the air mixing plate 1, and the direction marking line 21 ensures that the angle error of the rubber ring is small. At the same time, the installation efficiency is improved. The installation of both sides can be completed by lifting the upper cover plate 4 once, avoiding the risk of repeated handling of heavy parts.

[0064] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
