Description

Technical Field

[0001] This utility model relates to the technical field of screen assembly and flipping, specifically to an automatic screen flipping and assembly device. Background Technology

[0002] Automatic screen flipping assembly equipment is a key piece of equipment in the display device manufacturing industry. It is mainly used for flipping operations in the production process of products such as LCD screens and flat panel displays. In the production process of display products, due to the needs of various production processes, it is often necessary to flip the screen 180 degrees for corresponding operations, such as double-sided processing, inspection or assembly.

[0003] Existing automatic screen flipping assembly devices typically use a robotic arm to flip the display screen. However, the distance between the suction cups cannot be adjusted during the flipping process, making it impossible to adhere to the edges of the display screen and thus affecting the assembly work. In addition, a camera is used to calibrate the position of the suction cups, but the camera position is relatively fixed and cannot be flexibly adjusted to suit the positioning of different sized display screens, resulting in poor performance.

[0004] Therefore, we propose an automatic screen flipping assembly device to solve the problems mentioned above. Utility Model Content

[0029] In this embodiment: During use, the display screen can be adsorbed, fixed, and flipped by the robotic arm body 2 and the vacuum suction cup 69. Before adsorption, the distance between the two adsorption plates 67 can be adjusted. At this time, the operation of the camera body 88 can calibrate and position the adsorption point of the display screen, making it convenient for staff to observe on the display device. The position of the camera body 88 can also be adjusted according to the actual situation. The operation of the servo motor B81 drives the transmission gear 82 to rotate. When the transmission gear 82 rotates, it will drive the rotating gear 83 to rotate. At this time, the camera body 88 can be rotated through the circular seat 84, the arc block 85, the hydraulic push rod B87, and the connecting seat 86. In addition, the setting of the hydraulic push rod B87 can also adjust the position of the camera body 88, which is beneficial to To better position and calibrate the adsorption area, the servo motor A61 drives the active bevel gear 62 to rotate. The rotation of the active bevel gear 62 causes the driven bevel gears 63 on the front and rear sides to rotate synchronously. The rotation of the driven bevel gears 63 then drives the adjacent screw 64 to rotate. The rotation of the screw 64 causes the adjacent threaded sleeve 65 to move relative to or in opposite directions. During observation, the L-shaped fixing rod 66 can be used to move the adsorption plates 67 relative to or in opposite directions, thus adjusting the distance between the front and rear vacuum suction cups 69. After adjustment, the servo motor A61 can be stopped, allowing the vacuum suction cups 69 to adsorb and fix the display screen. After adsorption and fixation, the robotic arm body 2 can be moved to flip the display screen, facilitating assembly work for the staff.

[0030] Example 2 This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1 , Figure 4-6 and Figure 10The snap-fit ​​assembly 5 includes two side plates 51 fixedly installed on the right side of the U-shaped plate 4, with the side plates 51 arranged front and back. Threaded tubes 52 are movably installed through the upper middle part of each side plate 51. Threaded rods 53 extending to the outside are threadedly installed in the inner cavity of each threaded tube 52. T-shaped snap-fit ​​rods 54 are fixedly installed on the opposite end of each threaded rod 53. The opposite ends of the T-shaped snap-fit ​​rods 54 extend into the inner cavities of adjacent snap-fit ​​grooves 32. Worm gears 55 are fixedly installed on the opposite ends of the threaded tubes 52. A worm 56 meshes with the right side of the worm gear 55. A flat plate is fixedly installed above the right side of the U-shaped plate 4. The upper end of the worm 56 movably extends through to the outside of the flat plate, facilitating snap-fit ​​fixing between the U-shaped plate 4 and the U-shaped connecting plate 3, and making separation between the two convenient.

[0031] The threaded tube 52 and threaded rod 53 involved in this application have the same precision, which can meet the requirement of synchronous rotation, and the external threads of the threaded rods 53 on both sides are set in opposite directions.

[0032] A knob 561 is fixedly installed at the upper end of the worm 56 to facilitate the rotation of the worm 56.

[0033] A vertical plate 511 is fixedly installed at the middle of the top of the side plate 51, and a guide plate 512 is provided on the opposite side of the vertical plate 511.

[0034] In this embodiment: After assembly, the U-shaped plate 4 and the U-shaped connecting plate 3 can be disassembled and separated. By rotating the knob 561, the worm gear 56 can be rotated. When the worm gear 56 rotates, it will drive the threaded tubes 52 on the front and rear sides to rotate. When the threaded tubes 52 rotate, they will drive the adjacent threaded rods 53 to move relative to each other. When the threaded rods 53 move relative to each other, they will drive the adjacent T-shaped snap-fit ​​rods 54 to move in the opposite direction, thereby moving them away from the inner cavity of the adjacent snap-fit ​​groove 32. At this time, the U-shaped plate 4 and the U-shaped connecting plate 3 can be separated. After separation, it is also convenient for staff to perform maintenance and inspection work on the drive components, etc. The reverse operation can be used to snap and install the two together.
