Technical Field

[0001] This utility model relates to the field of glass coating technology, and in particular to a coating device that can adjust the coating end by detecting the glass thickness. Background Technology

[0002] Coated glass typically has one or more coating layers on its surface, which give it properties such as high gloss, oxidation resistance, acid and alkali resistance, and UV resistance. Spray coating is a glass coating method that involves spraying a coating liquid onto the glass surface using a spray gun or nozzle to form a coating layer, thus achieving the effect of coating the glass.

[0003] Existing coating devices typically use a spray gun to coat glass, but in practice, the coating end cannot be quickly adjusted or disassembled for maintenance. Therefore, we propose a coating device that can adjust the coating end by detecting the glass thickness. Utility Model Content

[0039] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0040] Example:

[0041] like Figures 1-6 As shown, a coating apparatus capable of detecting glass thickness and adjusting the coating end includes:

[0042] The operating table 1 has a support column fixed at its bottom end and a discharge hole inside it;

[0043] Fixed support block 2 is fixedly installed at the top center of the operating table 1, and has a discharge hole inside it;

[0044] Adjustment mechanism 3 is symmetrically arranged on the top of the operating table 1;

[0045] The mobile positioning mechanism 4 is located at the output end of the adjustment mechanism 3;

[0046] The coating mechanism 5 is movably inserted into the end of the moving positioning mechanism 4;

[0047] The glass thickness detection mechanism 6 is bolted to the top of the operating table 1;

[0048] Waste liquid collection box 7 is movably located below the operating table 1 and inside the fixed support block 2, with symmetrical casters at its bottom end.

[0049] The working principle of the above technical solution is as follows:

[0050] During use, the glass can be placed on top of the fixed support block 2, with one end of the glass positioned below the glass thickness detection mechanism 6. The glass thickness is then detected by the glass thickness detection mechanism 6. After detection, the glass is moved to below the connecting coating mechanism 5. The adjusting mechanism 3 drives the moving positioning mechanism 4, causing the moving positioning mechanism 4 to move the connecting coating mechanism 5. Under the action of the connecting coating mechanism 5, the glass surface can be coated. The operation is convenient and quick. Excess coating liquid can flow into the inside of the waste liquid collection box 7 through the discharge hole.

[0051] In another embodiment, such as Figure 2 As shown, the adjustment mechanism 3 includes a fixed guide frame 31. A first servo motor 32 is fixedly connected to one end of the fixed guide frame 31. The output end of the first servo motor 32 passes through the interior of the end of the fixed guide frame 31 and is fixedly connected to a movable threaded rod 33. A connecting limit plate 34 is fixedly connected to the end of the movable threaded rod 33 away from the first servo motor 32.

[0052] The first servo motor 32 can drive the movable threaded rod 33 and the connecting limit plate 34, so that the movable threaded rod 33 can move the moving positioning mechanism 4 and the connecting coating mechanism 5 during the rotation, so that the connecting coating mechanism 5 can stably coat the glass surface, making the operation convenient.

[0053] In another embodiment, such as Figure 3As shown, the mobile positioning mechanism 4 includes a first mobile mounting block 41, which is located on the outer side of the surface of the movable threaded rod 33 and the inner side of the fixed guide frame 31. A connecting limiting sleeve 42 is fixedly connected to one side of the first mobile mounting block 41. A fixed slot 43 is provided inside the connecting limiting sleeve 42. A positioning component body 44 is fixedly connected to one side of the connecting limiting sleeve 42.

[0054] This allows the bottom end of the connecting coating mechanism 5 to be easily inserted into the inside of the fixing slot 43, enabling the positioning component body 44 to restrict and fix the connecting coating mechanism 5, and allowing for quick assembly and disassembly of the connecting coating mechanism 5, making the operation convenient.

[0055] In another embodiment, such as Figure 3 As shown, the connecting coating mechanism 5 includes a movable insert rod 51. A fixed limiting groove 52 is provided on one side of the movable insert rod 51, and a fixed through groove 53 is provided on the top of the movable insert rod 51. A connecting mounting top plate 54 is fixedly connected to the top of the movable insert rod 51. A rectangular through groove 55 is provided inside the connecting mounting top plate 54. Fixed positioning blocks 56 are symmetrically provided on the top of the connecting mounting top plate 54. A bidirectional threaded rod 57 is movably connected inside the fixed positioning block 56. A second servo motor 58 is fixedly connected to one end of the bidirectional threaded rod 57, and a limiting end block 59 is fixedly connected to the other end of the bidirectional threaded rod 57. A movable clamping mechanism 510 is threadedly connected to the outer surface of the bidirectional threaded rod 57. A connecting nozzle 511 is movably clamped inside the movable clamping mechanism 510. A connecting delivery pipe 512 is fixedly connected to the outer side of the connecting nozzle 511.

[0056] This allows the second servo motor 58 to drive the bidirectional threaded rod 57, enabling the moving clamping mechanism 510 to move on the outer side of the surface of the bidirectional threaded rod 57 and the inner side of the rectangular through groove 55 when the bidirectional threaded rod 57 rotates. This, in turn, moves the connecting nozzle 511 to perform a coating process on the glass, making the operation convenient.

[0057] In another embodiment, such as Figure 4 As shown, the positioning component body 44 includes a connecting sleeve 441, a movable connecting rod 442 is movably connected to the connecting sleeve 441, a positioning block 443 is fixedly connected to one end of the movable connecting rod 442, a connecting mounting plate 444 is fixedly connected to the other end of the movable connecting rod 442, and a force-bearing spring 445 is fixedly connected between the side of the connecting mounting plate 444 away from the movable connecting rod 442 and the inner end of the connecting sleeve 441.

[0058] The movable insert rod 51 is inserted into the inner side of the fixed slot 43, so that the bottom edge of the movable insert rod 51 presses against the positioning block 443, causing the positioning block 443 to retract into the connecting sleeve 441 on its own. This drives the movable connecting rod 442 and the connecting mounting plate 444 to push, compressing the force spring 445, thereby adjusting itself. When the movable insert rod 51 is in a stable state inside the fixed slot 43, the force spring 445 pushes the connecting mounting plate 444, causing the movable connecting rod 442 and the positioning block 443 to move, so that the positioning block 443 is stably engaged inside the fixed limiting groove 52, thereby achieving connection and positioning.

[0059] In another embodiment, such as Figure 5 As shown, the movable clamping mechanism 510 includes a second movable mounting block 5101. A connecting arm 5103 is bolted to the outer side of the second movable mounting block 5101. A connecting base frame 5102 is bolted to the bottom end of the connecting arm 5103. Threaded sleeves 5104 are fixedly connected to both sides of the connecting base frame 5102. A connecting threaded rod 5105 is threaded to the inner side of the threaded sleeve 5104. One end of the connecting threaded rod 5105 passes through the interior of the connecting base frame 5102 and extends to the inner side of the connecting base frame 5102. A rotating end plate 5106 is fixedly connected to one end of the connecting threaded rod 5105. A connecting end plate 5107 is fixedly connected to the other end of the connecting threaded rod 5105. A movable sleeve block 5108 is movably sleeved on the outer side of the surface of the connecting end plate 5107. A connecting clamping plate 5109 is fixedly connected to one side of the movable sleeve block 5108.

[0060] The connecting nozzle 511 is placed inside the connecting base frame 5102. Then, the rotating end plate 5106 is rotated, which drives the connecting threaded rod 5105 and the connecting end plate 5107 to rotate. This allows the connecting threaded rod 5105 to move inside the threaded sleeve 5104, while the connecting end plate 5107 can rotate inside the movable sleeve block 5108. At this time, the connecting threaded rod 5105 pushes the connecting end plate 5107, the movable sleeve block 5108, and the connecting clamping plate 5109 to clamp and fix the connecting nozzle 511, so that the connecting nozzle 511 can be used stably and is easy to operate.

[0061] In another embodiment, such as Figure 6As shown, the glass thickness detection mechanism 6 includes connecting legs 61 symmetrically mounted on the top of the operating table 1 by bolts. One end of the connecting legs 61 is fixedly connected to a connecting mounting block 62. A connecting guide sleeve block 63 is fixedly connected to the top of one side of the connecting mounting block 62. A scaled connecting block 64 is movably connected inside the connecting guide sleeve block 63. A connecting base plate 65 is fixedly connected to the bottom of the scaled connecting block 64. A connecting top block 66 is fixedly connected to the top of the scaled connecting block 64. A connecting handle 67 is fixedly connected to the middle of the top of the connecting top block 66. The bottom end of the connecting guide sleeve block 63 is aligned with the zero mark on the surface of the scaled connecting block 64.

[0062] The connecting handle 67 is easily pulled upwards, causing the connecting top block 66, the graduated connecting block 64, and the connecting base plate 65 to move. Then, the end of the glass is positioned below the connecting base plate 65. Next, the connecting handle 67 is released, allowing the connecting base plate 65 and the graduated connecting block 64 to move downwards, so that the bottom of the connecting base plate 65 can contact the surface of the glass. The thickness of the glass is then measured by the cooperation between the connecting guide sleeve 63 and the graduated connecting block 64. The operation is convenient.

[0063] The working principle of this utility model is as follows: During use, the glass is placed on top of the fixed support block 2. Then, the connecting handle 67 is pulled upward, causing the connecting top block 66, the scaled connecting block 64, and the connecting base plate 65 to move. Next, the end of the glass is positioned below the connecting base plate 65. Then, the connecting handle 67 is released, causing the connecting base plate 65 and the scaled connecting block 64 to move downward, so that the bottom of the connecting base plate 65 can contact the surface of the glass. Based on the cooperation between the connecting guide sleeve 63 and the scaled connecting block 64, the thickness of the glass is detected. After the glass is detected, the glass thickness detection mechanism 6 is adjusted, and then the glass is reset. Then, the first servo motor 32 drives the movable threaded rod 33, causing the first movable mounting block 41 to move on the outer side of the surface of the movable threaded rod 33, driving the connecting limit sleeve 42, the positioning component body 44, the movable insert rod 51, the connecting mounting top plate 54, and the fixed positioning. The components 56, bidirectional threaded rod 57, second servo motor 58, moving clamping mechanism 510, and connecting nozzle 511 move to deliver coating agent into the connecting nozzle 511 through connecting delivery pipe 512, thus coating the glass surface. Then, the second servo motor 58 drives the bidirectional threaded rod 57, allowing the moving clamping mechanism 510 to move outside the surface of the bidirectional threaded rod 57, changing the position of the connecting nozzle 511 above the glass. Next, the first servo motor 32 drives the movable threaded rod 33, causing the first movable mounting block 41 to move outside the surface of the movable threaded rod 33, thereby moving the connecting limit sleeve block 42, positioning component body 44, movable insert rod 51, connecting mounting top plate 54, fixed positioning block 56, bidirectional threaded rod 57, second servo motor 58, moving clamping mechanism 510, and connecting nozzle 511 to re-coat the glass surface. The overall structure is simple and the operation is convenient and quick.When disassembly and maintenance are required, rotating the rotating end plate 5106 causes the connecting threaded rod 5105 and connecting end plate 5107 to rotate, allowing the connecting threaded rod 5105 to move inside the threaded sleeve 5104. Simultaneously, the connecting end plate 5107 rotates inside the movable sleeve 5108. At this time, the connecting threaded rod 5105 pulls on the connecting end plate 5107, the movable sleeve 5108, and the connecting clamping plate 5109, causing the connecting clamping plate 5109 to no longer clamp and fix the connecting nozzle 511, thereby... The nozzle 511 is disassembled and inspected. Then, the movable insert rod 51 is pulled upwards. Under the action of the edge of the fixed limiting groove 52, the positioning block 443 is squeezed, causing it to retract into the connecting sleeve 441. This pushes the movable connecting rod 442 and the connecting mounting plate 444, compressing the force spring 445 and causing it to be pulled out from the inside of the fixed limiting groove 52. The movable insert rod 51 is no longer restricted or fixed, allowing for quick disassembly and inspection. The overall structure is simple and the operation is convenient and fast.

[0064] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
