Description

Technical Field

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

[0002] During the production process of optical lenses, the surface of the lenses needs to be coated. Common coating processes include evaporation and sputtering. The corresponding coating process is selected according to different materials and process requirements. In the sputtering coating equipment, the target material is 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 sputtering the target material toward the material surface, the cylindrical bracket needs to rotate at a high speed so that the material surface 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 remain stable on the cylindrical bracket to prevent the material from being separated from the cylindrical bracket due to the influence of centrifugal force. In order to ensure the stability of the material on the cylindrical bracket, the current common practice is to manually stick the material to the cylindrical bracket with tape, and use the tape to stick the edges of the material to the cylindrical bracket. After the coating is completed, the tape is torn off and the coated material is taken away. The cylindrical bracket of the coating equipment is large in size. It takes a long time to manually attach the material to the cylindrical bracket one by one, which seriously restricts the coating efficiency of the material. In addition, the use of tape as a consumable also increases the coating cost. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] Embodiment 1: The present invention specifically discloses a coating bracket that is easy to hang materials, such as Figure 1 , Figure 3-Figure 6 As shown, it includes: a cylindrical bracket composed of a support shaft 1, a connecting ring 2 and an arc-shaped hanging plate 3, according to Figure 3 As shown, a plurality of connecting rings 2 are evenly spaced and installed on a supporting shaft 1, and an arc-shaped hanging plate 3 is installed and covered around the outer surface of the connecting ring 2, thereby forming a cylindrical bracket around the connecting ring 2; when in use, the cylindrical bracket is placed on the driving end in the coating chamber of the coating equipment through the supporting shaft 1, and the material to be coated needs to be fixed on the arc-shaped hanging plate 3, and as the cylindrical bracket rotates, the target material is sputtered from the side of the cylindrical bracket onto the surface of the material to form a coating layer.

[0030] according to Figure 1 , Figure 4 and Figure 5 As shown, in order to facilitate fixing the material on the cylindrical bracket, a torsion spring button frame 4 is provided on the cylindrical bracket. The torsion spring button frame 4 is detachably mounted on the connecting ring 2 through the fixed connecting pieces 5 provided at both ends thereof. A plurality of torsion spring button frames 4 are evenly arranged in a vertical state along the circumferential direction on the cylindrical bracket. The torsion spring button frames 4 include: a connecting plate 41. The two ends of the connecting plate 41 are respectively connected to the fixed connecting pieces 5, and are vertically mounted on the connecting ring 2 through the fixed connecting pieces 5. A sleeve 42 is provided on the connecting plate 41. The sleeves 42 are arranged in groups of two, and multiple groups are evenly spaced on the connecting plate 41. A double torsion spring button 43 is installed on the sleeve 42, and the button portion of the double torsion spring button 43 is against the surface of the arc-shaped hanging plate 3.

[0031] according to Figure 2 As shown, the surface of the arc hanging plate 3 is provided with step bars, which are connected end to end to form a circular ring and are installed on the surface of the arc hanging plate 3, and multiple step bars are arranged at intervals around the outer surface of the arc hanging plate 3 in the direction of the axial centerline of the support shaft 1.

[0032] Among them, the arc-shaped hanging plate 3 has three usage states because it is equipped with a torsion spring button frame 4 and a step bar. One is the first state in which the torsion spring button frame 4 exists alone, and the material to be coated is fastened to the arc-shaped hanging plate 3 through the torsion spring button frame 4.

[0033] The second state is a second state in which the step bar exists alone, and the material is stuck between the two step bars to be fixed on the arc hanging plate 3 .

[0034] The third is that the torsion spring button frame 4 and the step bar are cross-assembled and installed on the arc hanging plate 3, and the material is stuck between the two step bars and fastened by the torsion spring button frame 4.

[0035] In this embodiment, the first state is taken as an example. When in use, the double torsion spring button 43 is pulled up, and the material is placed between the double torsion spring button 43 and the arc-shaped hanging plate 3. Then the double torsion spring button 43 is loosened to fasten the material to the surface of the arc-shaped hanging plate 3. In this way, the material can be quickly and conveniently fixed on the cylindrical bracket.

[0036] according to Figure 5 As shown, a protruding rib 45 in a convex shape is provided in the middle of the connecting plate 41. The protruding rib 45 and the connecting plate 41 are integrally formed to form a T-shaped cross section. Through the protruding rib 45, the connecting plate 41 has a higher structural strength, and the plate body in the middle part is not easy to bend and deform, so that the double torsion spring button 43 can still have enough pressure against the surface of the arc-shaped hanging plate 3. The button part of the double torsion spring button 43 is provided with a concave curved inner concave part 44. The curved inner concave part 44 provided on the double torsion spring button 43 can be pulled up by pulling this part when in use, so as to facilitate use.

[0037] according to Figure 5 As shown, the fixed connection member 5 includes: a fixed block 51, which is fixedly connected to the end of the connecting plate 41 through a protruding extension 53 provided thereon, and 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, and the arc-shaped hanging plate 3 is located between the fixed block 51 and the connecting plate 41. A screw rod 52 is spirally connected to the fixed block 51, and by rotating the screw rod 52, the screw rod 52 is pushed out from the fixed block 51 and abuts against the inner wall of the connecting ring 2, so that the connecting plate 41 can be tightly clamped on the outer surface of the arc-shaped hanging plate 3 by rotating the screw rod 52.

[0038] When the torsion spring button frame 4 needs to be adjusted, the screw 52 can be rotated so that it no longer presses against the connecting ring 2, and then the torsion spring button frame 4 is pushed to slide along the connecting ring 2. In order to better make the fixing block 51 slide in the connecting ring 2, the installation roller 54 is rotated 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 ring wall of the connecting ring 2, so that the torsion spring button frame 4 will not be easily stuck when it is pushed.

[0039] Embodiment 2: When the curved hanging plate 3 is used in the second state, according to Figure 2 and Figure 8As shown, the step bar is a first arc bar 6, and two first arc bars 6 are provided. The two first arc bars 6 are hinged together to form an openable and closable ring, and are connected end to end by a movable buckle 62 to clamp on the outer surface of the arc hanging plate 3. The inner side wall of the first arc bar 6 facing the arc hanging plate 3 is symmetrically provided with a second step groove 61. When the first arc bar 6 is attached to the surface of the arc hanging plate 3, the second step groove 61 can allow the material to be placed therein. When in use, the first arc bar 6 is clamped on the outer surface of the arc hanging plate 3 by locking the movable buckle 62, and then the upper and lower sides of the material are inserted into the second step groove 61, so as to fix the material on the surface of the arc hanging plate 3.

[0040] Unlike the first embodiment, the structure of the fixing means of this embodiment is simpler; however, it should be noted that the coating material has different sizes depending on the final product, and when the material is fixed by step bars, it will be limited by the width of the material. When the tangent angle formed when the material width is attached to the surface of the arc hanging plate 3 exceeds the range that the step groove can allow, the material cannot be inserted into the groove and fixed on the surface of the arc hanging plate 3. In other words, the fixation method using step bars is only suitable for smaller materials, while the fixation method using the torsion spring button rack 4 can be used for larger materials. Although the small-sized materials can be fastened by reducing the spacing of the torsion spring button rack 4, this will cause the torsion spring button rack 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 material is flat, the two sides of the material are in a suspended state when it is directly attached to the arc-shaped hanging plate 3, and the double torsion spring buttons 43 directly press on both sides of the material and easily break the material. For this reason, it is necessary to stick a layer of film on the back of the material, and clamp the film with the double torsion spring buttons 43 to fix the large-sized material.

[0041] according to Figure 8 As shown, a wedge 63 is fixed on the inner wall of the first arc strip 6. When the first arc strip 6 is clamped on the arc hanging plate 3, the wedge 63 can be inserted into the connecting seam 301 between the arc hanging plates 3, so that when the cylindrical bracket rotates, the first arc strip 6 will not rotate in the opposite direction.

[0042] The present invention can selectively select a suitable use state according to the size of the material after the torsion spring button frame 4 and the step bar are arranged on the cylindrical bracket, so as to quickly fix the material on the cylindrical bracket; for example, when the material is small, the material can be clamped between two step bars to quickly and conveniently fix the material; when the material size is large, the torsion spring button frame 4 can be used to tightly buckle the material on the cylindrical bracket; or the torsion spring button frame 4 and the step bar can be combined with each other to fix the material more firmly; the torsion spring button frame 4 and the step bar are simple and convenient to use, and no tape is required for auxiliary fixation, which saves consumables and reduces costs.

[0043] Embodiment 3: When the arc hanging plate 3 is used in the third state, according to Figure 1 , Figure 6 and Figure 7 As shown, the step bar is the second arc bar 7, the connecting plate 41 is symmetrically provided with first step grooves 46 on both sides of the arc hanging plate 3, the two ends of the second arc bar 7 are inserted into the first step grooves 46 to keep the state of being attached to the arc hanging plate 3, the second arc bar 7 and the connecting plate 41 are perpendicular to each other, the second arc bar 7 is symmetrically provided with third step grooves 71 on both sides of the arc hanging plate 3, and after the second arc bar 7 is attached to the arc hanging plate 3, the material can be inserted into the third step grooves 71. This embodiment is a combination of a step bar and a torsion spring button frame 4, and the cylindrical bracket combines the advantages of embodiment 1 and embodiment 2, and is not limited by the size of the material when used.

[0044] according to Figure 5 and Figure 7 As shown, intermediate blocks 74 are installed at both ends of the second arc strip 7, and the ends of the intermediate block 74 are slidably connected to the stop blocks 77 through the insertion rod 76. The insertion rod 76 is provided with a second spring 78, and the second spring 78 is between the stop block 77 and the intermediate block 74. The function of the second spring 78 is to keep the stop block 77 in a pop-up state, and the end of the stop block 77 is against the first step groove 46, and the surface of the stop block 77 is provided with a sinking groove 79 matching the first step groove 46, so that the stop block 77 is not easy to tilt when it is stuck in the first step groove 46, and the first step groove 46 is provided with a positioning tooth 47, and the end of the stop block 77 contacting the first step groove 46 is provided with an engaging tooth 710, and the engaging tooth 710 is engaged with the positioning tooth 47 through the push of the second spring 78.

[0045] Specifically, after the second arc-shaped bar 7 is installed between the two torsion spring button frames 4, if the upper and lower spacing needs to be adjusted, the stop 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 bar 7 can be slid up and down in the first step groove 46 to adjust its position. The position of the second arc-shaped bar 7 can be adjusted without removing it. When the engaging teeth 710 are re-engaged with the positioning teeth 47, the second arc-shaped bar 7 is fixed.

[0046] according to Figure 7As 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.

[0047] 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.
