[0002] As the demand for AI computing power gradually increases, hardware circuits become increasingly complex. Both the previously widely used PCB organic substrates and TSV technology, which increases packaging density, will become bottlenecks restricting the production of high-performance computing chips such as AI chips in the foreseeable future. Glass substrates, with their inherent electrical properties, excellent mechanical properties, good thermal conductivity, and low coefficient of thermal expansion, have become a key research focus for new advanced packaging technology substrates.

[0003] In commercial applications, glass substrates are mainly 0.7mm and 0.5mm thick, and are about to enter the process of thinner (such as 0.4mm) thickness. Basically, a panel requires two glass substrates, one for the bottom glass substrate and the other for the base plate of the color filter. The bonding of glass substrates has been fully automated, with a robotic arm moving and positioning the glass substrates.

[0004] Currently, most robotic arms use fixed parameters to bond glass substrates, and the operation is consistent each time. However, the glass substrate may deviate after placement, which may cause misalignment in the electrical component connections after the robotic arm bonds the glass panel according to the fixed parameters, resulting in defective products. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a precise positioning device for multi-layer bonding of mini LED glass substrates, including an operating table 2, a lower suction cup 5, and a driving assembly. The lower suction cup 5 for adsorbing the glass substrate is located above the operating table 2. A robotic arm 1 for transferring the glass substrate is located on one side of the operating table 2. An upper suction cup 4 is located at the moving end of the robotic arm 1. A driving assembly is located at the connection between the upper suction cup 4 and the robotic arm 1. The upper suction cup 4 is rotatably connected to the movable end of the robotic arm 1. Detection modules 9 for detecting the edge position of the glass substrate are located at the edges of the adsorption surfaces of the upper suction cup 4 and the lower suction cup 5. A bevel 9 is formed on one side of the detection module 9. 03. A light emitter 901 and a light receiver 902 are provided on the inner side of the inclined side 903. The light emitter 901 and the light receiver 902 are arranged symmetrically. The glass substrate is adsorbed and fixed by the upper suction cup 4 and the lower suction cup 5. At the same time, the light emitter 901 emits light, which is reflected by the glass substrate and enters the light receiver 902 to determine that the detection module 9 is within the range of the glass substrate. Multiple detection modules 9 can be used in combination to obtain the edge position of the glass substrate, so that the robotic arm 1 and the drive motor 3 drive the upper suction cup 4 to produce corresponding movements and adjust the bonding position and angle.

[0023] Please see Figure 2In this embodiment, the driving assembly includes a drive motor 3, a first gear 406, a second gear 407, and a gear ring 403. A gear ring 403 is positioned above the upper suction cup 4 and is fixedly connected to it. A connecting seat 401 is provided at the movable end of the robotic arm 1. The drive motor 3 is positioned above the connecting seat 401. A second gear 407 is positioned inside the gear ring 403 and is rotatably connected to the connecting seat 401. A first gear 406 is positioned at the output end of the drive motor 3. The second gear 407 meshes with the first gear 406 and the gear ring 403. The connecting seat 401... A first mounting plate 404 is provided on the inner side, and a second mounting plate 405 is provided on the outer side of the gear ring 403. A thrust bearing 402 is provided in the space between the first mounting plate 404 and the second mounting plate 405. The cooperation of the first mounting plate 404, the thrust bearing 402 and the thrust bearing 403 rotatably connects the connecting seat 401 and the gear ring 403, thereby rotatably connecting the upper suction cup 4 to the movable end of the robotic arm 1. The drive motor 3 can drive the first gear 406 to rotate, and the planetary gear set composed of the gear ring 403, the first gear 406 and the second gear 407 increases the torque, so that the upper suction cup 4 rotates at a certain angle.

[0024] Please see Figures 3-4 In this embodiment, a communicating chamber 501 is formed on the inner side of the upper suction cup 4 and the lower suction cup 5. A connecting pipe 502 is provided on one side of the upper suction cup 4 and the lower suction cup 5. The connecting pipe 502 is connected to the communicating chamber 501 and the vacuuming device. A movable chamber 503 is formed on the inner side of the upper suction cup 4 and the lower suction cup 5. A piston 6 is provided on the inner side of the movable chamber 503. The piston 6 is slidably sealed to the inner wall of the movable chamber 503. A spring 7 is provided at the bottom of the piston 6. A thin film 8 is provided above the piston 6. The edge of the thin film 8 is fixedly connected to the upper suction cup 4 or the lower suction cup 5. When adsorbing and fixing the glass substrate, the vacuuming device uses the connecting pipe 502 to extract the air from the communicating chamber 501. The air pressure difference causes the piston 6 to move downward and compress the spring 7, and drives the middle part of the thin film 8 to move downward, thereby forming small cavities between the upper suction cup 4 or the lower suction cup 5 and the glass substrate. The air pressure difference is used to adsorb and fix the glass substrate.

[0025] In use, the vacuum equipment uses the connecting pipe 502 to extract the air from the communicating chamber 501. The pressure difference causes the piston 6 to move downward and compress the spring 7, which in turn causes the middle part of the film 8 to move downward. This creates small cavities between the upper suction cup 4 or the lower suction cup 5 and the glass substrate. The pressure difference is used to adsorb and fix the glass substrate. At the same time, the light emitter 901 emits light. The light is reflected by the glass substrate and enters the light receiver 902, which determines that the detection module 9 is within the range of the glass substrate. Multiple detection modules 9 can be used in combination to obtain the edge position of the glass substrate. The robotic arm 1 adjusts the position of the upper suction cup 4 according to the position of the glass substrate. The drive motor 3 drives the first gear 406 to rotate according to the position of the glass substrate. The planetary gear set composed of the gear ring 403, the first gear 406 and the second gear 407 increases the torque, causing the upper suction cup 4 to rotate at a certain angle, thereby making the adhesion of the upper and lower glass substrates more precise.

[0026] Through the above steps, the glass substrate is adsorbed and fixed by setting the upper suction cup 4 and the lower suction cup 5. At the same time, the light emitter 901 emits light, which is reflected by the glass substrate and enters the light receiver 902 to determine that the detection module 9 is within the range of the glass substrate. Multiple detection modules 9 can be used in combination to obtain the edge position of the glass substrate, so that the robotic arm 1 and the drive motor 3 drive the upper suction cup 4 to produce corresponding movements, and adjust the bonding position and angle.
