Description

Technical Field

[0001] The present invention relates to the technical field of glass cover plate coating, and particularly relates to a glass cover plate coating device with a chamber partition structure for rapid switching. Background Art

[0002] A glass cover plate, as a functional protection component based on ultra-thin glass, is formed through fine processing such as precision cutting, strengthening treatment, and coating processes. It is widely used in multiple high-end fields such as mobile phone screens, electronic displays, vehicle-mounted devices, and medical instruments. In the manufacturing process of glass cover plates, the coating link is particularly crucial, which is an important prerequisite to ensure that the glass cover plate has excellent scratch resistance and fingerprint resistance.

[0003] For glass cover plates in different usage environments, corresponding coating processes need to be flexibly matched. Taking AG coating as an example, by adopting advanced technologies such as ultrasonic spraying and vapor deposition, a microscopic rough structure is formed on the surface of the glass cover plate, thereby effectively achieving the anti-glare effect.

[0004] However, although ultrasonic spraying and vapor deposition are currently relatively common processing technologies, there are still certain limitations. First of all, traditional coating operations usually rely on a single device for processing. When facing the mass production of glass cover plates, it is difficult to meet the requirements of continuous coating operations, resulting in the need to further improve the processing efficiency. In addition, due to the presence of tiny unevenness on the surface of the glass cover plate, when using the above processes for coating, problems such as uneven spraying or covering defects are likely to occur, affecting the quality and performance of the final product.

[0047] The flipping group 32 includes a mating gear 321 rotatably penetrating through the C-shaped mounting frame 311 through a rotating shaft and fixedly connected to any side of the mounting plate 312. An inverted L-shaped rack 322 that is always meshed with the mating gear 321 is slidably arranged on one side of the vertical section of the C-shaped mounting frame 311 corresponding to the mating gear 321.

[0048] The pushing group 314 includes an electric push rod fixedly arranged on the robotic arm 3 through a connecting plate. Installation grooves are formed on the upper end face of the horizontal section of the C-shaped mounting frame 311 corresponding to the positions of the two covers 3131. A pushing block 3141 is slidably arranged inside the installation grooves. The telescopic end of the electric push rod is fixedly provided with a pushing plate 3142 that abuts against the pushing block 3141.

[0049] The upper end faces of the baffle 142 and the arc-shaped partition 1121 are both arranged in a bowl shape, that is, the heights of the upper end faces of the baffle 142 and the arc-shaped partition 1121 gradually decrease from the outside to the inside.

[0050] During specific implementation, it mainly includes the following steps:

[0051] 1. Clamping, limiting and transferring of the glass cover plates:

[0052] Initially, two glass cover plates are placed on the conveyor belts of the conveying device 13 that move in the same direction by manual or external equipment. As the glass cover plates move along with the conveyor belts towards the workbench 1 to the designated position, the robotic arm 3 is controlled to drive the C-shaped mounting frame 311 to rotate to directly above the two glass cover plates. Subsequently, the telescopic base 2 is controlled to drive the robotic arm 3 to move downward and gradually approach the glass cover plates.

[0053] When the C-shaped mounting frame 311 drives the mounting plate 312 to move downward, the glass cover plates will enter the interior of the clamping sleeve 3134. As the mounting plate 312 continues to press down, the clamping sleeve 3134 is compressed and retracted. The outer wall of the clamping sleeve 3134 is squeezed by the inner wall of the mounting sleeve 3132 during the retraction process and gradually changes from the initial slope shape to a vertical shape. At this time, the deformed clamping sleeve 3134 completes the clamping and limiting work on the glass cover plates through the annular groove opened inside it.

[0054] At the same time, during the retraction process of the clamping sleeve 3134, when the telescopic top block 3135 moves into the interior of the mounting sleeve 3132, due to the lack of a pushing force, the telescopic top block 3135 will quickly pop out and snap into the inner wall of the mounting sleeve 3132 to prevent the subsequent glass cover plates from falling off during the movement of the robotic arm 3. Finally, the robotic arm 3 is controlled to drive the two glass cover plates to move to directly above the coating tank one 11 and the coating tank two 12.

[0055] It is worth emphasizing that the clamping sleeve 3134 that completes the clamping and limiting of the glass cover plates is made of a material with a certain elasticity, aiming to avoid damaging the glass cover plates during the clamping process.

[0056] 2. Coating work on the glass cover plates:

[0057] The robotic arm 3 drives the two glass cover plates to move into the corresponding coating tank one 11 and coating tank two 12 respectively. The corresponding cover 3131 of the coating tank one 11 is in close contact with the mating groove one 111 after moving downward, and the corresponding cover 3131 of the coating tank two 12 is also in close contact with the mating groove two 121 after moving downward.

[0058] Inside the coating tank 11, the external motor drives the driving gear 141 through the output shaft to rotate synchronously with the four driven gears 143. At this time, the toggle rods 145 provided on the four driven gears 143 toggle the corresponding T-shaped connecting blocks 1122 to rotate during the rotation process. The four spray heads 112 and the baffle plate 142 are driven by the T-shaped connecting blocks 1122 to move synchronously closer or farther away. During the movement of the four spray heads 112, the coating material is continuously ejected through their ejection ports to complete the spraying work on the lower end surface of the glass cover. At the same time, when the four driven gears 143 rotate, they will drive the internal gear ring 1461 and the linkage block 1463 to rotate. During the rotation process of the linkage block 1463, through its cooperation with the cover 3131, the cover 3131, the mounting sleeve 3132, and the glass cover inside the mounting sleeve 3132 are driven to rotate. Through the movement of the four spray heads 112 in cooperation with the continuous rotation of the glass cover, the blind area during the coating work of the glass cover can be effectively reduced, and the quality of the coating work of the glass cover can be further improved.

[0059] Inside the coating tank 12, before the vapor deposition coating work is carried out, the coating tank 12 needs to be evacuated in cooperation with the external vacuum equipment. Subsequently, the material to be coated on the material rack 123 evaporates and moves upward to the surface of the glass cover. When the external motor drives the bidirectional lead screw 1221 to rotate, the material rack 123 moves up and down reciprocally along with the movement of the bidirectional lead screw 1221. At the same time, during the rotation of the mounting disc 1222, it will drive the glass cover corresponding to the coating tank 12 to rotate synchronously through the driving rod 1223. The rotation of the glass cover in cooperation with the movement of the material rack 123 can avoid problems such as uneven spraying or covering defects caused by the fine unevenness on the surface of the glass cover.

[0060] It should be emphasized that when the C-shaped mounting frame 311 drives the glass cover to move downward, the inverted L-shaped rack 322 provided thereon will first approach the workbench 1. Through the cooperation of the square groove and the inverted L-shaped rack 322, the relative positions of the glass cover and the corresponding coating tank 11 and coating tank 12 are adjusted, so that the glass cover can stably enter the inside of the corresponding coating tank 11 and coating tank 12.

[0061] III. Flipping work of the glass cover:

[0062] After the coating work on one side of the glass cover is completed, the manipulator 3 is controlled to drive the two glass covers away from the coating tank 11 and the coating tank 12, and then rotate 180 degrees and move to the other working area. As the telescopic base 2 gradually moves downward, the inverted L-shaped rack 322 is pushed by the square groove and moves in the opposite direction. At this time, the tooth part of the inverted L-shaped rack 322 meshes with the gear 321 and drives the mating gear 321 and the mounting plate 312 to rotate.

[0063] As the angle of the mounting plate 312 changes, the clamping sleeve 3134 inside the cover 3131 and the L-shaped weight 3133 also move synchronously under the action of gravity. When the mounting plate 312 completes a 180-degree flipping operation, the clamping sleeves 3134 and the glass cover plate inside the two covers 3131 slide to the lowermost end of the flipped mounting sleeve 3132 under gravity, thus completing the flipping operation of the glass cover plate. Finally, by repeating the above operations, the coating work on both sides of the glass cover plate can be completed.

[0064] It should be emphasized that the coating tanks one 11 and two 12 in the two processing groups are arranged in a staggered direction. The purpose is to ensure that different coating processes are realized on two aspects during the coating work of the glass cover plate. This method is to make full use of the advantages of different coating processes and meet the diverse requirements of the glass cover plate at the same time.

[0065] IV. Blanking work of the glass cover plate:

[0066] After the coating work on both sides of the glass cover plate is completed, control the robotic arm 3 to rotate to the other conveying device 13, adjust the position of the C-shaped mounting frame 311 so that both glass cover plates are above the middle conveyor belt, and then control the electric push rod to drive the push plate 3142 to extend. The downward force of the push plate 3142 is used to push the push block 3141. The clamping part 31 of the clamping sleeve 3134 gradually disengages from the mounting sleeve 3132 under the action of the push block 3141. When the clamping part 31 is fully opened, the glass cover plate inside it will fall onto the middle conveyor belt.

[0067] It should be emphasized that when the glass cover plate completes the second coating work and moves away from the workbench 1, the reset of the inverted L-shaped rack 322 drives the mating gear 321 and the mounting plate 312 to rotate until they return to the initial position.

[0068] It is worth noting that the above glass cover plate coating equipment with a fast-switching chamber partition structure has the following advantages:

[0069] Advantage 1: In this embodiment, the coating forming equipment for the glass cover plate adopts a dual-processing-group design, with two coating tanks in each group, forming a multi-chamber parallel operation mode, significantly enhancing the continuity and coordination of the processes, effectively avoiding the waiting and switching time in the single-chamber operation of the glass cover plate, and effectively improving the efficiency of the coating work of the glass cover plate.

[0070] Advantage Two: The internal design of the driven gear 143 in the coating tank 11 and the synchronous motion mechanism of the spraying head 112 greatly reduce the blind area during the coating process. The synchronous motion of the glass cover plate and the spraying head 112 ensures the uniform distribution and efficient deposition of the coating material, thereby improving the coating quality and efficiency. At the same time, the arc-shaped partition 1121 and the baffle plate 142 provided in the coating tank 11 can prevent the micro-coating material from freely falling due to gravity during the operation of the ultrasonic spraying head 112, thus avoiding the pollution of the coating tank 11.

[0071] Advantage Three: In the vapor deposition work in the coating tank 12, the combination of the up-and-down reciprocating motion of the material placement rack 123 and the rotation of the glass cover plate reduces the uneven coverage caused by the tiny unevenness on the surface of the glass cover plate, further improving the quality of the vapor deposition of the glass cover plate.

[0072] Advantage Four: The cooperation between the inverted L-shaped rack 322 and the square groove during the downward movement completes the position adjustment of the glass cover plate with respect to the coating tank 11 and the coating tank 12, enabling the glass cover plate to stably and accurately enter the coating tank 11 and the coating tank 12, laying a foundation for the subsequent coating work.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
