Description

Technical Field

[0001] The utility model relates to the technical field of glass coating processing, in particular to a general coating correction plate structure. Background Art

[0002] Glass coating is a method of changing the optical properties of glass by coating one or more layers of metal, alloy or metal compound film on the glass surface. The coated glass has the advantages of preventing paint surface oxidation and aging, improving glass strength, corrosion resistance and high temperature resistance, preventing scratches and reducing the difficulty of glass cleaning. In the industry, four methods are mainly used to achieve the coating operation on the glass surface, namely chemical deposition method, thermal evaporation coating, mechanical coating (including spraying and dipping) and vacuum sputtering coating. Among them, vacuum sputtering coating uses a vacuum sputtering coating machine. First, an inert gas (usually Ar gas) is made to generate charged ions through the glow discharge phenomenon. The charged ions are accelerated by an electric field and then strike the surface of the target material, causing the target material atoms to be bombarded and fly out to generate secondary electrons. The secondary electrons then strike the gas atoms, thus forming more charged ions. Finally, the target material atoms with a certain kinetic energy reach the surface of the object to be coated (substrate) for deposition, thereby realizing the coating operation on the substrate surface. The coating machine correction plate is an important component of the vacuum sputtering coating machine. By adjusting its shape and position, it changes the movement trajectory of sputtering particles (such as metal atoms, ions, etc.), making the distribution of sputtering particles more uniform to ensure the uniformity of the deposited film thickness. At the same time, the correction plate can also block non-sputtering substances to prevent non-sputtering substances from contaminating the coating surface.

[0003] Currently, the commonly used coating machine correction plate in the industry (as shown in Figure 1 ) includes a carrier plate 1 fixed on the coating equipment and a plurality of baffles 3 connected to the carrier plate 1 by screws 2. A plurality of screw holes 4 are provided on the carrier plate 1, and a U-shaped groove 5 is provided at the end of the baffle 3. By placing the U-shaped groove 5 in different screw holes 4, the length of the baffle 3 is adjusted to adjust the current-cutting shape of each part of the correction plate to ensure the uniformity of coating. For the above correction plate structure, since the baffle adopts a groove structure, the target material will deposit and fill the groove after coating, making the baffle unable to move and adjust, thus causing the baffle to be scrapped and increasing the cost of the correction plate. Moreover, since the U-shaped groove and the screw are used in combination for locking for adjustment, the adjustment distance of the baffle is limited by the opening length of the U-shaped groove, and the adjustable range is small. Therefore, baffles of different lengths need to be used for secondary adjustment. The types of baffles involved in the adjustment process of the correction plate are numerous, thus increasing the production and storage costs. In addition, since screw holes at multiple different height positions are used to adjust the length of the baffle, it is necessary to frequently disassemble and assemble the baffle to achieve long-distance adjustment. The operation is complex, the time-consuming for adjusting the length of the correction plate baffle is long, and the length adjustment efficiency is low. Summary of the Utility Model

[0027] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be made with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] The utility model discloses a general coating correction plate structure, which can avoid the deposition and filling of the target material to extend the service life of the rack. The length adjustment range of the rack is large, and only a single rack is required to meet various length adjustments, without the need to select multiple racks to achieve secondary adjustment of the rack length. Moreover, the rack is loosened or fixed by screwing the limit bolt, reducing the difficulty of rack length adjustment.

[0029] Specifically, please combine Figure 2-7, the general coating correction plate structure 10 of this embodiment includes a mounting base 100, a protective cover 200, a rack assembly, and an adjusting assembly. A through groove 110 is formed in the mounting base 100 and penetrates through two opposite side surfaces of the mounting base 100. A plurality of screw holes 120 are formed in the upper surface of the mounting base 100 and are arranged at intervals along the length direction of the mounting base 100. The screw holes 120 communicate with the through groove 110, and the mounting base 100 has a first side corresponding to one end opening of the through groove 110 and a second side corresponding to the other end opening of the through groove 110. In this embodiment, the through groove 110 extends along the width direction of the mounting base 100. The protective cover 200 is covered on the upper surface of the mounting base 100. An adjusting space 210 is formed between the lower surface of the protective cover 200 and the upper surface of the mounting base 100. The protective cover 200 is used to protect the adjusting assembly and the screw holes 120 on the mounting base 100 to prevent the adjusting assembly and the mounting base 100 from being damaged by the ejected target material. The rack assembly includes a plurality of racks 300 arranged side by side. The racks 300 are used to intercept the steam released by the auxiliary heating device of the coating machine to change the movement trajectory of the sputtering particles, so that the sputtering particles are more evenly distributed on the surface of the substrate. In this embodiment, by adjusting the length of each rack 300 extending out of the first side, the exposed lengths of the racks 300 are different to form a specific shape, and the uniformity of the deposited film thickness is achieved by intercepting the steam. The rack 300 is inserted into the through groove 110, and the insertion depth of the rack 300 into the through groove 110 is adjustable. At least one end of the rack 300 extends out of the through groove 110 and forms a steam intercepting portion 310 on the first side of the through groove 110. This steam intercepting portion 310 is used to intercept the steam released by the auxiliary heating device. The adjusting assembly includes a plurality of limit bolts 400 corresponding to each rack 300. The limit bolts 400 pass through the screw holes 120 and are in threaded cooperation with the screw holes 120. The head of the limit bolt 400 is located in the adjusting space 210, and the tail of the limit bolt 400 abuts against the upper surface of the rack 300. That is to say, each rack 300 is limited by a limit bolt 400 passing through a corresponding screw hole 120. When it is necessary to adjust the length of the rack 300 extending out of the first side, that is, to adjust the length of the steam intercepting portion 310, only need to rotate the limit bolt 400 to separate the tail of the limit bolt 400 from the upper surface of the rack 300, release the constraint of the limit bolt 400 on the rack 300, and then the rack 300 can be pulled outward or pushed inward in the through groove 110 to adjust the length of the steam intercepting portion 310 of the rack 300.

[0030] For the above-mentioned general coating correction plate structure 10, a through groove 110 is opened on the mounting base 100, and the rack 300 is fixed by the pressing method of the limit bolt 400. There is no need to provide a hole groove structure on the rack 300, which can avoid the problem of difficult movement of the rack 300 caused by the deposition and filling of the target material in the hole groove, extend the service life of the rack 300, and reduce the use cost of the correction plate structure; the design of the through groove 110 structure ensures that the rack 300 can slide in the through groove 110 to adjust the length of its extension from the first side. The adjustable length of the rack 300 is extended to the length of the rack 300, increasing the adjustable range of the extension length of the rack 300. There is no need to use multiple racks 300 with different lengths for secondary adjustment, reducing the adjustment difficulty of the extension length of the rack 300 and the production and storage costs of the rack 300; the length of the rack 300 extending from the first side is adjusted by pressing and limiting with the limit bolt 400 and the sliding of the rack 300 in the through groove 110. There is no need to frequently disassemble and assemble the rack 300, reducing the adjustment difficulty of the extension length of the rack 300 and improving the adjustment efficiency of the extension length of the rack 300.

[0031] The mounting base 100 is used to support and mount the rack assembly and limit the rack assembly. In this embodiment, the mounting base 100 at least includes two relatively arranged limiting baffles 130, an upper pressing plate 140 located above the two limiting baffles 130 and fixedly connected to the limiting baffles 130, and a mounting plate 150 located below the two limiting baffles 130 and fixedly connected to the limiting baffles 130. The upper pressing plate 140, the mounting plate 150 and the two limiting baffles 130 jointly enclose a through groove 110. Each screw hole 120 is arranged along the length direction of the upper pressing plate 140 and penetrates through the upper surface and the lower surface of the upper pressing plate 140. The protective cover 200 is fixedly connected to the upper surface of the upper pressing plate 140. The mounting plate 150 is used to be fixedly connected to the inner wall of the vacuum chamber of the coating machine to realize the installation of the correction plate structure. The upper pressing plate 140 is used to carry the limiting bolt 400 to realize the installation of the limiting bolt 400. The limiting baffle 130 is used to separate the upper pressing plate 140 and the mounting plate 150 and limit the size of the through groove 110 in the thickness direction of the mounting plate 150. In this embodiment, the size of the through groove 110 in the thickness direction of the mounting plate 150 is larger than the thickness of the rack 300, so that when the limiting bolt 400 is loosened, the rack 300 can slide smoothly in the through groove 110. Further, the ratio of the size of the through groove 110 in the thickness direction of the mounting plate 150 to the thickness of the rack 300 is between 11:10 - 12:10, which reduces the sway of the rack 300 in the through groove 110 while ensuring the smooth sliding of the rack 300. In order to further reduce the sway of the rack 300 in the through groove 110, a plurality of partitions are arranged at intervals on the surface of the mounting plate 150 located in the through groove 110 to divide the through groove 110 into several sliding areas. The partitions extend along the width direction of the mounting plate 150, and each rack 300 is correspondingly and slidably embedded in a sliding area. In this way, through the common restraint of adjacent partitions or the partitions and the limiting baffles 130, the limit of the rack 300 can be realized to avoid the sway of the rack 300 during the adjustment process. During actual production, according to the size of the limiting baffle 130, the number of the limiting baffles 130 can be further increased to ensure the stability of the support of the limiting baffle 130 on the upper pressing plate 140 and the mounting plate 150. In addition, it should be emphasized that in this embodiment, the number of the racks 300 is the same as the number of the limiting bolts 400 to ensure that each rack 300 has a corresponding limiting bolt 400 for positioning; the number of the racks 300 is less than or equal to the number of the screw holes 120. In this way, according to the installation position of the mounting base 100 in the vacuum chamber and the area of the sputtering particles that need to be intercepted, an appropriate number of racks 300 can be selected.

[0032] In one embodiment, the limiting baffle 130, the upper pressing plate 140, and the mounting plate 150 are integrally formed. For example, the mounting seat 100 composed of the limiting baffle 130, the upper pressing plate 140, and the mounting plate 150 can be obtained by die casting, or a through groove 110 can be cut on the plate to obtain the mounting seat 100 composed of the limiting baffle 130, the upper pressing plate 140, and the mounting plate 150. In another embodiment, the mounting seat 100 further includes a first screw 160. The first screw 160 sequentially passes through the upper pressing plate 140 and the limiting baffle 130 and is inserted into the mounting plate 150. That is to say, the limiting baffle 130, the upper pressing plate 140, and the mounting plate 150 are all independent components. The three can be separately processed and fixed together by the first screw 160 to achieve the detachable connection of the three. In this way, when some components are damaged, only the damaged components can be replaced to reduce the use cost of the correction plate structure.

[0033] Furthermore, in one embodiment, the mounting plate 150 includes a plate body 151, a first fin 152 and a second fin 153 which are arranged on two opposite sides of the plate body 151 and are respectively fixedly connected to the plate body 151. The connection line between the middle of the first fin 152 and the middle of the second fin 153 is parallel to the length direction of the plate body 151. One limiting baffle 130 is fixed on the first fin 152, and the other limiting baffle 130 is fixed on the second fin 153, and the shape of the upper pressing plate 140 is adapted to the shape of the mounting plate 150. It can also be understood that the mounting plate 150 has a T-shaped structure or a cross-shaped structure to prevent the connection parts between the mounting plate 150 and the limiting baffle 130 and between the upper pressing plate 140 and the limiting baffle 130 from interfering with the sliding of the rack 300. Preferably, both the mounting plate 150 and the upper pressing plate 140 have a T-shaped structure. In addition, in this embodiment, the first fin 152, the second fin 153, and the plate body 151 are integrally formed. The connection parts between the first fin 152 and the plate body 151 and between the second fin 153 and the plate body 151 are respectively screw-connected to the upper pressing plate 140, and the middle of the plate body 151 is also screw-connected to the upper pressing plate 140 to improve the overall structural stability of the mounting seat 100 and prevent the upper pressing plate 140 or the mounting plate 150 from deforming when subjected to external pressure.

[0034] In one embodiment, the two side edges of the protective cover 200 are bent towards the adjusting space 210 to form supporting feet 220, and the bottom of the supporting feet 220 is bent towards the direction away from the adjusting space 210 to form connecting pieces 230 that abut against the upper surface of the mounting base 100. A limiting notch 240 is formed at the edge of the connecting piece 230; the general-purpose coating correction plate structure 10 further includes a second screw 170. The second screw 170 passes through the limiting notch 240 and is inserted into the mounting base 100, and the head of the second screw 170 abuts against the edge of the limiting notch 240. Of course, the limiting notch 240 at the edge of the connecting piece 230 can also be replaced with a through hole, and the second screw 170 passes through the through hole and the head of the second screw 170 abuts against the edge of the through hole to fix the protective cover 200 on the mounting base 100. The protective cover 200 can be in a rectangular structure or can be adapted to the shape of the upper pressing plate 140, that is, the protective cover 200 can also be in a T-shaped structure or a cross-shaped structure. Preferably, in this embodiment, the shape of the protective cover 200 is adapted to the shape of the upper pressing plate 140 to fully shield the limiting bolt 400 and the screw hole 120 and achieve the protection of the limiting bolt 400 and the screw hole 120.

[0035] To improve the structural stability of the protective cover 200, in one embodiment, the general-purpose coating correction plate structure 10 further includes a reinforcing bracket 500. The reinforcing bracket 500 is located between the protective cover 200 and the mounting base 100, and the reinforcing bracket 500 is fixedly connected to the lower surface of the protective cover 200 and the upper surface of the mounting base 100 respectively. The edge of the reinforcing bracket 500 adjacent to the first side, the lower surface of the protective cover 200, and the upper surface of the mounting base 100 jointly enclose the adjusting space 210. Each screw hole 120 is arranged along the edge of the upper surface of the mounting base 100 and is respectively communicated with the adjusting space 210 and the through groove 110. Further, the reinforcing bracket 500 is integrally formed with the upper pressing plate 140. The reinforcing bracket 500 can be in a cross-shaped structure, a feng-shaped structure, a square-shaped structure or a tree-shaped structure. By arranging the reinforcing bracket 500 between the lower surface of the protective cover 200 and the upper surface of the mounting base 100, the supporting surface of the mounting base 100 for the protective cover 200 is increased, so as to avoid the problem of damage to the protective cover 200 caused by excessive local pressure on the protective cover 200, extend the service life of the protective cover 200, and ensure the protection effect of the protective cover 200 on the limiting bolt 400 and the screw hole 120.

[0036] The limiting bolt 400 includes a stud and a screw head located at the head of the stud, the cross section of the screw head is a pentagonal or hexagonal structure, or the outer surface of the screw head is provided with a toggle portion, so that the limiting bolt 400 can be rotated by twisting the screw head or the toggle portion on the screw head to lock or release the rack 300. Preferably, the limiting bolt 400 is a knurled screw. In this embodiment, the height of the adjustment space 210 is greater than or equal to the difference between the length of the limiting bolt 400 and the depth of the screw hole 120 to meet the moving stroke of the limiting bolt 400 in the height direction of the mounting seat 100; the height of the adjustment space 210 is less than the length of the limiting bolt 400 to avoid the problem of difficulty in resetting the limiting bolt 400 caused by the limiting bolt 400 rotating too many times and the limiting bolt 400 being separated from the screw hole 120 and falling out of the adjustment space 210 during the adjustment process of the rack 300.

[0037] For the mounting seat 100 structure fixed by screws, when assembling the correction plate structure, firstly, the upper pressing plate 140, the limiting baffle 130 and the mounting plate 150 are locked by the first screw 160 to form the mounting seat 100 with the through slot 110; then, the racks 300 are evenly arranged, the racks 300 are inserted into the through slots 110, and the limiting bolts 400 are tightened so that the limiting bolts 400 press the racks 300 one by one. After the racks 300 are fixed, the mounting plate 150 is fixed on the mounting position of the coating equipment, the protective cover 200 is covered, and the protective cover 200 is locked by the second screw 170. For the mounting seat 100 structure formed in an integral manner, it is only necessary to insert the racks 300 into the through slots 110, and tighten the limiting bolts 400, so that the limiting bolts 400 press the racks 300 one by one, and the mounting seat 100 is fixed on the coating equipment and the protective cover 200 is installed.

[0038] When adjusting the correction plate structure, first use optical testing instruments to perform initial inspection of the coated product and record its surface quality, optical performance and other parameters; based on the test results, analyze the possible problems with the correction plate structure and formulate a corresponding correction plan; then, according to the correction plan, make necessary adjustments to the correction plate structure, including adjusting the angle, position, height and other parameters of the correction plate structure; then use calipers, micrometers and other tools to accurately measure the adjusted correction plate structure to ensure that it meets the equipment requirements and the parameter requirements in the correction plan; finally, use optical testing instruments to retest the coating effect until the required parameter indicators are met.

[0039] The shape and position of the correction plate structure are key factors affecting the coating uniformity. By adjusting the shape (such as trimming, bending, etc.) and position (such as angle, height, etc.) of the correction plate structure, the light path or material flow during the coating process can be changed, thereby improving the uniformity of the film layer. In this solution, through the improvement of the correction plate structure, the adjustment range is increased, the service life is extended, the fixture cost is saved, and the operation of employees is facilitated. The correction plate structure has at least the following beneficial effects:

[0040] 1) The adjustment range of the rack 300 is wide. The rack 300 adopts a fixing method of being pressed by the limit bolt 400, and as long as there is a surface on the surface of the rack 300 that can be pressed, fixation can be achieved; at the same time, the through groove 110 structure solves the interference problem of the inward movement of the rack 300, so that the adjustment range can reach the length of the rack 300 itself.

[0041] 2) The service life of the rack 300 is long. There are no groove, hole position and other characteristic profiles on the rack 300, and there are no characteristics that can be damaged after the target material is sprayed on, and the sliding adjustment of the rack 300 is not affected, so it can be used for a longer time.

[0042] 3) The types and quantities of processing of the rack 300 are reduced, saving raw materials and processing costs. The adjustable range of a single type of rack 300 has reached the adjustment requirements, and there is no need to replace racks 300 of different lengths for length adjustment; moreover, the service life of the rack 300 is extended, and there is no need to prepare too many racks 300 for replacement, saving the production, manufacturing and storage costs of the correction plate structure.

[0043] 4) The adjustment method of the correction plate structure is simplified, and the operation can be completed without using tools. The original screws needed to be tightened using a hex wrench; now, with the limit bolt 400, only hand tightening is required to adjust the tightness of the limit bolt 400, greatly improving the machine adjustment efficiency.

[0044] 5) The consumable cost is reduced. The application of the protective cover 200 replaces the protective effect of the original high-temperature tape, and there is no need to replace the tape every time of adjustment; moreover, the protective cover 200 can be recycled, and there is no need to worry about the service life problem and no short-term replacement is required, which not only saves the consumable cost, but also improves the protection effect.

[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0046] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent.
