Description

Technical Field

[0001] The present invention relates to the technical field of glass cover plate coating, and in particular to an automatic coating device for a glass cover plate. Background Art

[0002] The glass cover is a thin sheet made of transparent glass material, which is mainly used to protect the screens of electronic devices such as smartphones and tablets with touch screens as a high-strength "armor". It is also used in household appliances such as washing machines, refrigerators, microwave ovens, etc. to prevent the outer shell from being scratched or damaged.

[0003] Depending on the usage environment, in some cases, the glass cover will be coated to change its optical properties, improve thermal insulation or reduce UV transmittance, etc. The coating of glass plates mainly includes vacuum resistance heating evaporation, electron gun heating evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, ion beam sputtering, etc.

[0004] The authorization announcement number is: CN117758221B discloses a vacuum glass coating equipment and process, which divides an integrated coating umbrella into multiple coating umbrella units, and then uses the method of unfolding them to facilitate personnel to take and place glass substrates, thereby improving work efficiency; it can prevent the glass substrate from being damaged due to edge collapse due to deformation during the coating process, and prevent the clamping unit from blocking the coating of the glass substrate, thereby improving the yield rate; the sputtering coating covers a wide range, the coating is more uniform, and the work quality is improved.

[0005] However, there is a significant limitation in the glass surface coating process described in the above patent: it can only achieve single-sided coating, which means that after completing the coating operation on one side, the production process must be suspended, and the staff must manually remove the glass plate, flip it, and then put it back into the equipment for coating on the other side. This tedious and time-consuming manual flipping step not only increases the time cost in the production process, but also may lead to a significant decrease in coating efficiency, thereby reducing the overall glass coating production. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that it can only achieve single-sided coating, which means that after completing the coating operation on one side, the production process must be suspended, and the staff must manually remove the glass plate, flip it, and then put it back into the equipment to coat the other side.

[0011] The compression member includes two fixed rods fixedly connected to one side of the slide slot, and the outer peripheries of the two fixed rods are slidably connected with abutment blocks in contact with the abutment plate, the outer peripheries of the two fixed rods are sleeved with telescopic springs, and a clamping plate is connected between the abutment block and the fixed member.

[0012] As a further description of the above technical solution:

[0013] The fixing member comprises a rotating rod rotatably mounted inside the clamping plate and the welding block. One end of the two rotating rods passes through the welding block and the clamping plate respectively and is connected to the fixing plate. The welding block and the rotating rod are connected via a bearing.

[0014] As a further description of the above technical solution:

[0015] The interior of the limit plate is provided with a slot, the inner walls of the slot are fixedly connected with a fixing column, the outer periphery of the fixing column is connected to a limit block via a torsion spring, and one side of the limit block abuts against the limit plate.

[0016] As a further description of the above technical solution:

[0017] The rotating assembly includes a mounting plate installed on one side of the abutment block and a rotating disk fixedly connected to the outer periphery of a rotating rod near the mounting plate, a positioning rod is fixedly connected to the top of the mounting plate, and a rotating gear is rotatably connected to the outer periphery of the positioning rod, the rotating gear and the top of the rotating disk are both connected to a welding plate via an extension rod and a connecting column, and the rotating gear is connected to the vacuum chamber via a gear plate.

[0018] As a further description of the above technical solution:

[0019] A limiting component is connected to one side of the L-shaped plate, and the limiting component includes a connecting plate installed on one side of the L-shaped plate, and a plurality of inclined blocks installed on the outer periphery of the rotating rod away from the rotating gear. A groove is opened inside the connecting plate, and a plurality of connecting frames are fixedly connected to the inner wall of the groove.

[0022] As a further description of the above technical solution:

[0023] The power mechanism includes a servo motor installed inside the vacuum chamber, the output end of the servo motor is connected to a rotating shaft, the top of the rotating shaft is connected to a connecting rod, the top of the connecting rod passes through the frame and the vacuum chamber and is connected to a rotating disk, and a limiting groove for limiting the sliding of the limiting column is opened on the surface of the rotating disk.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] In the coating process, the start of the servo motor is the key first step. Its power is transmitted to the connecting rod through the rotating shaft, thereby driving the rotating disk to rotate smoothly. The rotation of the rotating disk not only activates the entire coating system, but also guides the moving block to move along the predetermined trajectory in the moving groove through the precise cooperation of the limiting groove and the limiting column. In this process, the abutment block in the L-shaped plate gradually moves away from the abutment plate under the elastic force of the telescopic spring as the moving block contracts inward, and slides down along the fixed rod to the inside of the L-shaped plate. When the abutment block is completely separated from the abutment plate, it contacts the L-shaped plate and pushes the clamping plate and the fixed plate to approach the glass cover plate body, finally achieving a stable clamping of the glass cover plate body;

[0026] As the two fixed plates successfully clamp the glass cover body, the moving block just enters the rotating groove. At this time, the magnetic radiation generator is activated, and the continuous rotation of the rotating disk drives the moving block to rotate in the rotating groove, thereby uniformly coating the glass cover body;

[0027] It is worth noting that when the moving block rotates, it will also push the limit block to rotate with the fixed column as the center and exert pressure on the torsion spring. When the moving block is separated from the limit block, the limit block is quickly reset under the elastic force of the torsion spring and is tightly abutted against the limit plate, thereby effectively preventing the position of the glass cover body from shifting during the coating process and ensuring the stability of the coating quality.

[0028] In addition, with the synchronous rotation of the L-shaped plate, the mounting plate, the positioning rod and the rotating gear also rotate accordingly. Driven by the gear plate, the rotating gear not only rotates by itself, but also drives the rotating disk to rotate synchronously through the transmission mechanism of the extension rod, the welding plate and the connecting column. The rotation of the rotating disk further drives the fixed plate to flip over, so that both sides of the glass cover body can be evenly coated. At the same time, the application of bearings effectively reduces the friction during the rotation process, ensuring the synchronous rotation of the fixed plate and the improvement of the coating efficiency.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figure 1-Figure 10As shown, the present invention provides an automatic coating equipment for a glass cover plate: comprising a frame 10, the frame 10 is connected to a magnetron system 12 (generating a strong magnetic field for forming plasma on the surface of a target material and controlling the movement of the plasma through a magnetic field) through a vacuum chamber 11 connected at the top, a vacuum pumping system 13 (for extracting air in the vacuum chamber 11 to create a high vacuum environment), an inert gas supply system 14 (providing a rarefied gas, usually an inert gas such as argon, to maintain the gas atmosphere in the vacuum chamber 11) and an exhaust gas treatment system 15 (treating the exhaust gas generated in the vacuum chamber 11 to ensure environmental friendliness and safe operation), and a closed cover plate 111 is installed on the top of the vacuum chamber 11.

[0048] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, it also includes: a power mechanism 20 assembled at the bottom of the vacuum chamber 11 and an installation assembly 30 installed inside the vacuum chamber 11, the installation assembly 30 includes a plurality of connecting frames 33 fixedly installed on the inner wall of the vacuum chamber 11 and a fixing frame 31, a magnetic radiation generator 32 is installed at the bottom of the fixing frame 31, a glass cover body 35 to be coated is placed on one side of the connecting frame 33 through a placing plate 34, the connecting frame 33 is connected with two rows of placing plates 34 that are far apart, the surface where the connecting frame 33 is connected to the placing plate 34 is set to be an arc surface, and the placing plate 34 is connected to the connecting frame 33. The position of the upper and lower sides of the glass cover body 35 does not exceed the center line (does not exceed the rotating rod 468, so as to facilitate the turning over of the glass cover body 35), and is only used for placing the glass cover body 35. The power mechanism 20 includes a servo motor 21 installed inside the vacuum chamber 11, and the output end of the servo motor 21 is connected to a rotating shaft 22, and the top of the rotating shaft 22 is connected to a connecting rod 23. The top of the connecting rod 23 passes through the frame 10 and the vacuum chamber 11 and is connected to a rotating disk 24. The surface of the rotating disk 24 is provided with a limiting groove 241 for limiting the sliding of the limiting column 45;

[0049] When the glass cover body 35 needs to be precisely coated, the closed cover 111 is first opened, and then the glass cover body 35 to be coated is carefully placed between two placement plates 34 preset on one side of the connecting frame 33 to ensure the stability and safety of the glass cover body 35 in the initial stage of the coating process;

[0050] After confirming that the glass cover body 35 has been correctly placed, we quickly close the closed cover 111 to facilitate the construction of a closed and controllable coating environment, effectively isolating the influence of external factors on the coating process;

[0051] Next, we start the magnetic control system 12, which uses magnetic field to precisely control the coating material to ensure the uniformity and quality of the coating layer. At the same time, the vacuum system 13 starts to work to extract the air in the coating room to achieve the required vacuum degree, creating an ideal oxygen-free environment for the deposition of the coating material.

[0052] Then the inert gas supply system 14 is activated to inject a proper amount of inert gas into the coating chamber. These gases play a role in protecting and promoting the deposition of coating materials during the coating process, while the exhaust gas treatment system 15 is responsible for treating the exhaust gas generated during the coating process to ensure the cleanliness and safety of the working environment;

[0053] After all the preparations are ready, we start the servo motor 21, driving the rotating shaft 22 to start rotating smoothly. Through the precise transmission of the connecting rod 23, the rotating disk 24 rotates at a uniform speed. This step not only provides the necessary power for the uniform deposition of the coating material on the glass cover body 35, but also ensures the continuity and stability of the coating process.

[0054] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the inner wall of the vacuum chamber 11 is connected to a limiting assembly 40, which includes a limiting plate 41 fixedly mounted on the inner wall of the vacuum chamber 11, and the limiting plate 41 is provided with a communicating moving groove 411 and a rotating groove 412, the inner wall of the moving groove 411 is slidably connected with a moving block 44, and both sides of the moving block 44 are arranged as arc surfaces to ensure that it can rotate in the rotating groove 412, the moving block 44 is slidably connected with the rotating disk 24 through a limiting column 45 connected to the top, one side of the moving block 44 is connected with an L-shaped plate 46, and a slide groove 463 is provided inside the L-shaped plate 46, the inner wall of the vacuum chamber 11 is fixedly connected with an abutting plate 462, the inner wall of the slide groove 463 is connected with a compression member abutting against the abutting plate 462, and the compression member It includes two fixed rods 465 fixedly connected to one side of the slide groove 463, and the outer peripheries of the two fixed rods 465 are slidably connected with abutment blocks 464 in contact with the abutment plate 462, the outer peripheries of the two fixed rods 465 are sleeved with telescopic springs 466, a clamping plate 467 is connected between the abutment block 464 and the fixing member, a welding block 461 is connected to one side of the L-shaped plate 46, and a fixing member is connected between the welding block 461 and the compression member, and the fixing member includes a rotating rod 468 rotatably installed inside the clamping plate 467 and the welding block 461, one end of the two rotating rods 468 passes through the welding block 461 and the clamping plate 467 respectively and is connected to the fixed plate 469, and the welding block 461 and the rotating rod 468 are connected through a bearing 47;

[0055] As the rotating disk 24 rotates at a constant speed, the limiting groove 241 thereon accurately guides the limiting column 45 to move along a predetermined trajectory, thereby driving the moving block 44 to slide smoothly in the moving groove 411. As the moving block 44 gradually shrinks inward, the structure inside the L-shaped plate 46 begins to change, and the abutting block 464 is gradually separated from the abutting plate 462 under the traction of the moving block 44.

[0056] At this time, the telescopic spring 466 in the contracted state responds quickly, and uses its elastic potential energy to push the abutment block 464 to slide smoothly along the outer periphery of the fixing rod 465. During the sliding process, the abutment block 464 skillfully descends slowly along the inclined surface of the abutment plate 462. This design ensures the stability of the action. As the abutment block 464 descends, the clamping plate 467 connected thereto also moves downward, thereby driving the rotating rod 468 and the fixing plate 469 to slowly approach the glass cover body 35 to be coated.

[0057] When the abutment block 464 is completely separated from the abutment plate 462, it contacts the other part of the L-shaped plate 46. At this time, the two fixing plates 469 firmly clamp the glass cover body 35 at a precise position to ensure that it will not be displaced or shaken during the coating process.

[0058] At the same time, the moving block 44 just moves into the rotating groove 412. This action indicates that the coating preparation work is fully completed. Then the magnetic jet generator 32 is started, so that it can evenly coat the surface of the glass cover body 35 under the continuous rotation of the rotating disk 24. The rotation of the rotating disk 24 not only promotes the uniform distribution of the coating material, but also improves the coating efficiency, ensuring that the quality and thickness of the coating layer reach the optimal state.

[0059] like Figure 7 As shown, a slot 42 is provided inside the limit plate 41, and a fixing column 421 is fixedly connected between the inner walls of the slot 42. The outer periphery of the fixing column 421 is connected to a limit block 422 through a torsion spring 423. The side of the limit block 422 abutting against the limit plate 41 is set to be an arc surface adapted to the moving block 44, and one side of the limit block 422 abuts against the limit plate 41.

[0060] During the coating process, as the moving block 44 continues to rotate in the rotating groove 412, it not only drives the coating operation to proceed smoothly, but also cleverly interacts with the limiting block 422 to ensure the stability and accuracy of the coating. Specifically, the movement of the moving block 44 will push the limiting block 422 to rotate around the fixed column 421. During this process, the torsion spring 423 is squeezed and stores elastic potential energy. When the moving block 44 contacts the limiting block 422 and pushes it to the position of closing the moving groove 411, the coating area is effectively isolated, preventing the moving block 44 from moving out of the rotating groove 412.

[0061] However, as the coating operation progresses or the rotating disk 24 continues to rotate, the moving block 44 will eventually break away from the contact with the limiting block 422. At this time, the previously squeezed torsion spring 423 quickly releases its elastic potential energy, pushing the limiting block 422 to reset, so that it is closely contacted with the limiting disk 41 again. This design ingeniously prevents the problem of uneven coating caused by the position change of the glass cover body 35 during the coating process, and ensures the stability of the coating quality.

[0062] It is worth noting that after the coating operation is completed, a reverse operation is required to remove the glass cover body 35. First, the magnetic control system 12, the vacuum system 13, the inert gas supply system 14 and the exhaust gas treatment system 15 need to be turned off to ensure that the environment in the coating room returns to normal. Then, the rotating disk 24 starts to rotate in the opposite direction through the reverse rotation of the servo motor 21. During this process, the moving block 44 moves along a predetermined path under the constraints of the limiting column 45 and the rotating groove 412, and slides along the surface of the limiting block 422 abutting against the limiting disk 41. This sliding action not only guides the processed glass cover body 35 to return to the initial position between the two rows of placement plates 34 with the clamping action of the fixed plate 469, but also realizes the release of the clamping state of the glass cover body 35.

[0063] As the L-shaped plate 46 gradually moves outward, the abutment block 464 contacts the abutment plate 462 again. Under the action of the contact force, the abutment block 464 is pushed upward, thereby driving the entire L-shaped plate 46 and its attached structure to return to the initial state. In this process, the distance between the two fixed plates 469 is also restored, preparing for the next coating operation or the removal of the glass cover. The entire operation process is reasonably designed and the movements are smooth, fully demonstrating the efficiency and stability of the equipment.

[0064] like Figure 1 , Figure 4 , Figure 6 , Figure 8 , Fig. 9 As shown, and a rotating assembly 50 installed on one side of the compression member, the rotating assembly 50 includes a mounting plate 51 installed on one side of the abutment block 464 and a rotating disk 57 fixedly connected to the outer periphery of the rotating rod 468 near the mounting plate 51, a positioning rod 52 is fixedly connected to the top of the mounting plate 51, and a rotating gear 53 is rotatably connected to the outer periphery of the positioning rod 52, the rotating gear 53 and the top of the rotating disk 57 are both connected to a welding plate 55 through an extension rod 54 and a connecting column 56, the rotating gear 53 is connected to the vacuum chamber 11 through a gear plate 58, and the height of the gear plate 58 is flush with the rotating gear 53 after the descent;

[0065] In the coating process, the rotation of the L-shaped plate 46 is crucial. As the moving block 44 rotates stably in the rotating groove 412, the L-shaped plate 46 is synchronously driven, and the abutment block 464 thereon and the mounting plate 51 connected thereto also perform circular motion;

[0066] As the mounting plate 51 rotates, the positioning rod 52 and the rotating gear 53 are driven together to move along a preset track. During this process, the rotating gear 53 meshes with the gear plate 58 fixedly mounted on the inner wall of the vacuum chamber 11, thereby realizing the active rotation of the rotating gear 53. This design cleverly utilizes the principle of gear transmission to convert the rotational motion of the mounting plate 51 into the rotational power of the rotating gear 53, providing a strong driving force for the subsequent coating operation.

[0067] The rotation of the rotating gear 53 forms a stable linkage with the rotating disk 57 through the close cooperation of the extension rod 54, the welding plate 55 and the connecting column 56. When the rotating gear 53 rotates, these components work together to drive the rotating disk 57 to rotate synchronously. This design not only realizes the effective transmission of energy, but also ensures the stability and accuracy of the rotation movement.

[0068] As the rotating disk 57 rotates, the rotating rod 468 and the fixed plate 469 connected thereto also flip over 180 degrees. This flipping action is crucial for the double-sided coating of the glass cover body 35. During the flipping process, the firm connection between the welding block 461 and the rotating rod 468 and the lubrication of the bearing 47 play a key role. The presence of the bearing 47 greatly reduces the friction during the rotation process, so that the two fixed plates 469 can flip synchronously and smoothly, thereby achieving uniform coating on both sides of the glass cover body 35.

[0069] like Figure 1 , Figure 4 , Figure 6 , Fig.10 As shown, a limiting assembly 60 is connected to one side of the L-shaped plate 46, and the limiting assembly 60 includes a connecting plate 61 installed on one side of the L-shaped plate 46, and a plurality of tilting blocks 62 installed on the outer periphery of the rotating rod 468 away from the rotating gear 53. A groove is provided inside the connecting plate 61, and a plurality of connecting frames 63 are fixedly connected to the inner wall of the groove. A center column 64 is fixedly installed on the inner wall of the connecting frame 63. A toggle sleeve 65 in contact with the tilting block 62 is connected to the outer periphery of the center column 64, and a plurality of spring sheets 66 are connected to the inside of the groove, and the spring sheets 66 are also in contact with the toggle sleeve 65.

[0070] During the operation of the coating device, when the rotating rod 468 rotates, the inclined block 62 designed on its periphery cleverly interacts with the toggle sleeve 65, and the toggle sleeve 65 rotates around the central column 64 through the pressing action, and at the same time compresses the spring sheet 66 to store elastic potential energy. This design not only ensures that the rotating rod 468 can rotate smoothly, but also maintains the stability and controllability of the rotation action through the feedback force of the spring sheet 66;

[0071] However, in the critical link of flipping the glass cover body 35, in order to prevent the problem of inconsistent flipping angles caused by interference from external factors, it is necessary to ensure that the rotating rod 468 can only rotate in one direction. In the interaction between the rotating rod 468 and the toggle sleeve 65, a one-way locking mechanism is hidden, which allows the rotating rod 468 to rotate smoothly during the flipping process, but is hindered in the opposite direction and cannot rotate. This design greatly ensures the uniformity and accuracy of the flipping angle of the glass cover body 35, and avoids the problem of uneven coating caused by angle deviation.

[0072] Working principle: During the coating process, the glass cover body 35 to be coated must first be placed securely between the placement plates 34 on both sides of the connecting frame 33 by opening the closed cover plate 111, and then the closed cover plate 111 must be quickly closed to ensure the closedness of the operating environment. Next, the magnetic control system 12, the vacuum system 13, the inert gas supply system 14 and the exhaust gas treatment system 15 must be started in sequence, and a series of preparations must be performed until all systems are ready.

[0073] At this time, the servo motor 21 is started, and its power is transmitted to the connecting rod 23 through the rotating shaft 22, thereby driving the rotating disk 24 to rotate slowly. The rotation of the rotating disk 24 not only drives the operation of the entire coating system, but also guides the moving block 44 to move orderly in the moving groove 411 through the precise cooperation between the limiting groove 241 and the limiting column 45. In this process, the abutting block 464 in the L-shaped plate 46 gradually moves away from the abutting plate 462 as the moving block 44 contracts inwardly under the action of the telescopic spring 466, and slides down along the fixing rod 465 to the inside of the L-shaped plate 46. When the abutting block 464 is completely separated from the abutting plate 462, it contacts the L-shaped plate 46, and pushes the clamping plate 467 and the fixing plate 469 to move closer to the glass cover body 35, finally achieving a stable clamping thereof.

[0074] As the two fixing plates 469 successfully clamp the glass cover body 35, the moving block 44 just moves into the rotating groove 412, and the magnetic radiation generator 32 is activated at this time. The continuous rotation of the rotating disk 24 drives the moving block 44 to rotate in the rotating groove 412, thereby achieving uniform coating of the glass cover body 35;

[0075] It is worth noting that, during the rotation of the moving block 44, it will also push the limiting block 422 to rotate with the fixed column 421 as the center, and squeeze the torsion spring 423. When the moving block 44 is separated from the limiting block 422, the limiting block 422 is quickly reset under the action of the torsion spring 423, and is closely abutted against the limiting plate 41, effectively preventing position deviation during the coating process and ensuring the coating quality.

[0076] In addition, as the L-shaped plate 46 rotates, the mounting plate 51, the positioning rod 52 and the rotating gear 53 also rotate accordingly. Driven by the gear plate 58, the rotating gear 53 not only rotates itself, but also drives the rotating disk 57 to rotate synchronously through the transmission effect of the extension rod 54, the welding plate 55 and the connecting column 56. The rotation of the rotating disk 57 further drives the fixed plate 469 to flip 180 degrees, so that both sides of the glass cover body 35 can be evenly coated. At the same time, the use of the bearing 47 effectively reduces the friction during the rotation process, ensuring the synchronous rotation of the fixed plate 469 and the improvement of the coating efficiency.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
