Description

Technical Field

[0001] The present invention relates to the technical field of sputtering coating, and in particular, to a coating bracket that is easy to hang workpieces. Background Art

[0002] During the production of optical lenses, it is necessary to coat the surface of the lenses. The common coating processes mainly include evaporation coating and sputtering coating. The corresponding coating process is selected according to different materials and process requirements. In the sputtering coating equipment, the target is located in the middle of the coating chamber, and the material to be coated is placed on a cylindrical bracket in the coating chamber. During the process of the target sputtering towards the surface of the material, the cylindrical bracket needs to rotate at a high speed so that the surface of the material is evenly coated with a film layer. Since the cylindrical bracket needs to rotate at a high speed in the coating chamber, the material needs to be kept stable on the cylindrical bracket to prevent the material from detaching from the cylindrical bracket under the influence of centrifugal force. In order to ensure the stability of the material on the cylindrical bracket, the common current method is to manually stick the material on the cylindrical bracket with tape, stick the edges of the material around the cylindrical bracket with the tape, and tear off the tape to take away the coated material after the coating is completed. However, the cylindrical bracket of the coating equipment is huge, and it takes a long time to manually attach the materials to the cylindrical bracket one by one, which seriously restricts the coating efficiency of the materials, and the use of tape as a consumable also increases the coating cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application rather than all the structures are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0029] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] Embodiment 1: The present invention specifically discloses a coating bracket that is easy to hang components, as Figure 1 , Figures 3 - 6 shown, including: a cylindrical bracket formed by connecting a support shaft 1, a connecting ring 2, and an arc-shaped hanging plate 3. As Figure 3 shown, a plurality of connecting rings 2 are evenly installed on the support shaft 1 at intervals, and the arc-shaped hanging plate 3 is installed covering the outer surface of the connecting ring 2, thereby forming a cylindrical bracket around the connecting ring 2. During use, the cylindrical bracket is placed on the driving end in the coating chamber of the coating equipment through the support shaft 1, and the material to be coated needs to be fixed on the arc-shaped hanging plate 3. As the cylindrical bracket rotates, the target material sputters from the side of the cylindrical bracket onto the surface of the material to form a coating layer.

[0031] As Figure 1 , Figure 4 and Figure 5 shown, in order to facilitate fixing the material on the cylindrical bracket, a torsion spring buckle bracket 4 is provided on the cylindrical bracket. The torsion spring buckle bracket 4 is detachably installed on the connecting ring 2 through the fixing connectors 5 provided at both ends thereof. A plurality of torsion spring buckle brackets 4 are arranged on the cylindrical bracket at intervals along the circumferential direction in a vertical state. The torsion spring buckle bracket 4 includes: a connecting plate 41. Both ends of the connecting plate 41 are respectively connected to the fixing connectors 5 and are vertically installed on the connecting ring 2 through the fixing connectors 5. A sleeve 42 is provided on the connecting plate 41. The sleeves 42 are grouped in pairs, and multiple groups are evenly provided on the connecting plate 41 at intervals. A double torsion spring buckle 43 is installed on the sleeve 42, and the buckle part of the double torsion spring buckle 43 abuts against the surface of the arc-shaped hanging plate 3.

[0032] As Figure 2As shown, the arc-shaped hanging plate 3 is provided with stepped strips on its surface. The stepped strips are connected end to end to form a circular ring and are arranged at intervals on the surface of the arc-shaped hanging plate 3 in the direction of the axis of the support shaft 1, with multiple such arrangements.

[0033] Among them, due to the configuration of the torsion spring buckle bracket 4 and the stepped strips, the arc-shaped hanging plate 3 has three usage states. One is the first state where only the torsion spring buckle bracket 4 exists. The material to be coated is fastened to the arc-shaped hanging plate 3 through the torsion spring buckle bracket 4.

[0034] The second is the second state where only the stepped strips exist. The material is clamped between two stepped strips to be fixed on the arc-shaped hanging plate 3.

[0035] The third is that the torsion spring buckle bracket 4 and the stepped strips are cross-combined and installed on the arc-shaped hanging plate 3. The material is clamped between two stepped strips and fastened by the torsion spring buckle bracket 4.

[0036] In this embodiment, the first state is taken as an example. During use, the double torsion spring buckle 43 is pulled up. After pulling up, the material is placed between the double torsion spring buckle 43 and the arc-shaped hanging plate 3, and then the double torsion spring buckle 43 is released to tightly fasten the material on the surface of the arc-shaped hanging plate 3. In this way, the material can be quickly and conveniently fixed on the cylindrical bracket.

[0037] According to Figure 5 As shown, a protruding rib 45 in a convex shape is provided in the middle of the connecting plate 41. After the protruding rib 45 and the connecting plate 41 are integrally formed, the cross-section is T-shaped. Through the provided protruding rib 45, the connecting plate 41 has higher structural strength, and the plate body in the middle part is not prone to bending deformation, so that sufficient pressure can still be ensured for the double torsion spring buckle 43 against the surface of the arc-shaped hanging plate 3. The buckle part of the double torsion spring buckle 43 is provided with an inward concave curved concave part 44. The curved concave part 44 provided on the double torsion spring buckle 43 can be pulled up by pulling this part during use for convenient use.

[0038] According to Figure 5 As shown, the fixed connecting piece 5 includes: a fixed block 51. The fixed block 51 is fixedly connected to the end of the connecting plate 41 through a protruding extension part 53 provided thereon. The connecting plate 41 is attached to the surface of the arc-shaped hanging plate 3, and the fixed block 51 is located on the inner wall of the connecting ring 2. At this time, the arc-shaped hanging plate 3 is between the fixed block 51 and the connecting plate 41. A screw 52 is spirally penetrated through the fixed block 51. By rotating the screw 52, the screw 52 protrudes from the fixed block 51 and abuts against the inner wall of the connecting ring 2. Therefore, by rotating the screw 52, the connecting plate 41 can be tightly clamped on the outer surface of the arc-shaped hanging plate 3.

[0039] When it is necessary to adjust the torsion spring button holder 4, the screw 52 can be rotated so that it no longer abuts against the connecting ring 2, and then the torsion spring button holder 4 is pushed to slide along the connecting ring 2. In order to better enable the fixing block 51 to slide within the connecting ring 2, a roller 54 is rotatably installed on the fixing block 51 on the side facing the connecting ring 2. After the screw 52 is loosened, the roller 54 rolls on the inner circumferential wall of the connecting ring 2, so that the torsion spring button holder 4 will not be easily stuck when pushed.

[0040] Embodiment 2: When used in the second state of the arc-shaped hanging plate 3, according to Figure 2 and Figure 8 As shown, the stepped strip is the first arc-shaped strip 6. There are two first arc-shaped strips 6. The two first arc-shaped strips 6 are hinged together to form an openable and closable ring, and are fastened to the outer surface of the arc-shaped hanging plate 3 by the movable buckle 62 end to end. Second stepped grooves 61 are symmetrically formed on the inner side wall of the first arc-shaped strip 6 on the side facing the arc-shaped hanging plate 3. When the first arc-shaped strip 6 fits on the surface of the arc-shaped hanging plate 3, the second stepped grooves 61 can allow materials to be placed therein. During use, the first arc-shaped strip 6 is fastened to the outer surface of the arc-shaped hanging plate 3 by tightening the movable buckle 62, and then the upper and lower sides of the material are inserted into the second stepped grooves 61, thereby fixing the material on the surface of the arc-shaped hanging plate 3.

[0041] Different from the first embodiment, the structure of the fixing measure in this embodiment is simpler; however, it should be noted that the coating materials vary in size according to the final products. When the stepped strip is used to fix the materials, it is limited by the width of the materials. When the tangent angle formed by the width of the materials attached to the surface of the arc-shaped hanging plate 3 exceeds the range that the stepped grooves can allow to be placed, the materials cannot be inserted into the grooves and fixed on the surface of the arc-shaped hanging plate 3. That is to say, the method of using the stepped strip for fixing is only suitable for materials with smaller sizes, while the method of fixing by the torsion spring button holder 4 can be applied to materials with larger sizes. Although the distance between the torsion spring button holders 4 can be reduced to fasten the small-sized materials, this will cause the torsion spring button holders 4 to occupy more space on the cylindrical bracket, resulting in a significant reduction in the number of materials that can be hung. At the same time, considering that the materials are flat, when directly attached to the arc-shaped hanging plate 3, both sides of the materials are in a suspended state, and the double torsion spring buttons 43 directly pressing on both sides of the materials are likely to break the materials. Therefore, a film needs to be pasted on the back of the materials, and the double torsion spring buttons 43 are used to clamp the film, so that the large-sized materials can be fixed.

[0042] According to Figure 8 As shown, a wedge 63 is fixedly provided on the inner side wall of the first arc-shaped strip 6. When the first arc-shaped strip 6 is fastened to the arc-shaped hanging plate 3, the wedge 63 can be inserted into the connecting seam 301 between the arc-shaped hanging plates 3, so that the first arc-shaped strip 6 will not rotate in the opposite direction during the rotation of the cylindrical bracket.

[0043] After the torsion spring buckle bracket 4 and the stepped strip are provided on the cylindrical bracket, the present invention can selectively select a suitable use state according to the size of the workpiece, so as to quickly fix the workpiece on the cylindrical bracket. For example, when the workpiece is small, the workpiece can be clamped between the two stepped strips to quickly and conveniently fix the workpiece. When the size of the workpiece is large, the workpiece can be tightly fastened on the cylindrical bracket by the torsion spring buckle bracket 4. Or through the combination of the torsion spring buckle bracket 4 and the stepped strip, the workpiece can be fixed more firmly. The provided torsion spring buckle bracket 4 and the stepped strip are simple and convenient to use. At the same time, no tape is required for auxiliary fixation, saving consumable consumption and reducing costs.

[0044] Example 3: When used in the third state of the arc-shaped hanging plate 3, according to Figure 1 , Figure 6 and Figure 7 shown, the stepped strip is the second arc-shaped strip 7. The connecting plate 41 is symmetrically provided with first stepped grooves 46 on both sides of the arc-shaped hanging plate 3. The two ends of the second arc-shaped strip 7 are inserted into the first stepped grooves 46 to keep it in a state of being attached to the arc-shaped hanging plate 3. The second arc-shaped strip 7 and the connecting plate 41 are perpendicular to each other. The second arc-shaped strip 7 is symmetrically provided with third stepped grooves 71 on both sides of the arc-shaped hanging plate 3. After the second arc-shaped strip 7 is attached to the arc-shaped hanging plate 3, the material can be inserted into the third stepped grooves 71. This embodiment combines the stepped strip and the torsion spring buckle bracket 4. The cylindrical bracket combines the advantages of Embodiment 1 and Embodiment 2 and is not limited by the size of the material during use.

[0045] According to Figure 5 and Figure 7 shown, intermediate blocks 74 are installed at both ends of the second arc-shaped strip 7. The end of the intermediate block 74 is slidably connected with a pressing block 77 through an insertion rod 76. A second spring 78 is provided on the insertion rod 76. The second spring 78 is between the pressing block 77 and the intermediate block 74. The function of the second spring 78 is to keep the pressing block 77 in a popped state. The end of the pressing block 77 abuts against the first stepped groove 46, and a sinking groove 79 matching the first stepped groove 46 is provided on the surface of the pressing block 77. In this way, it is not easy for the pressing block 77 to tilt when it is inserted into the first stepped groove 46. The first stepped groove 46 is provided with positioning teeth 47, and the end of the pressing block 77 in contact with the first stepped groove 46 is provided with engaging teeth 710. The engaging teeth 710 are engaged with the positioning teeth 47 by the push of the second spring 78.

[0046] Specifically, after the second arc-shaped strip 7 is installed between the two torsion spring buckle brackets 4, if it is necessary to adjust the vertical distance, the pressing block 77 can be pinched and pulled to disengage the engaging teeth 710 at its end from the positioning teeth 47. After disengagement, the second arc-shaped strip 7 can be slid up and down in the first stepped groove 46 to adjust the position. The second arc-shaped strip 7 can complete the position adjustment without being removed. When the engaging teeth 710 and the positioning teeth 47 are re-engaged, the second arc-shaped strip 7 is fixed.

[0047] according to Figure 7 As shown, the ends of both ends of the second arc strip 7 are provided with protruding connecting parts 72, at this time, the middle block 74 is connected to the protruding connecting part 72 by sliding up and down through the guide rod 73, and a first spring 75 is provided on the guide rod 73, and the first spring 75 is distributed on the upper and lower sides of the protruding connecting part 72, and the second arc strip 7 and the middle block 74 are connected by sliding. At this time, the two are kept flush by the first spring 75, and the second arc strip 7 has a small range of up and down sliding function through the action of the spring. The purpose of this arrangement is that since the upper and lower sides of the material need to be inserted into the first The second arc strip 7 can only be fixed in the three-step groove 71, and moving the second arc strip 7 by pulling the engaging teeth 710 and the positioning teeth 47 out of engagement can easily damage the material, and is also inconvenient to operate. However, through the action of the guide rod 73 and the first spring 75, before placing the material, it is only necessary to adjust and fix the basic position of the second arc strip 7, and then it is only necessary to slide the second arc strip 7 up and down to increase the distance between the two second arc strips 7. After the material is placed, the second arc strip 7 can be released and it can automatically restore to the original distance, thereby locking the material, which is simple and convenient to operate.

[0048] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
