Description

Technical Field

[0002] OLED displays, or Organic Light Emitting Diodes, are a newly emerging type of display used in mobile phone LCDs, hailed as the "dream display." OLED is also known as the third generation of display technology. OLEDs are not only thinner and lighter, but also consume less energy, have higher brightness, better luminous efficiency, and can display pure black. Furthermore, they can be bent, as seen in today's curved-screen TVs and mobile phones. Major international manufacturers are now investing heavily in OLED technology research and development, leading to its increasingly widespread application in televisions, computers (monitors), mobile phones, tablets, and other fields.

[0035] In summary, the vacuum adsorption OLED display glass feeding machine provided by this utility model allows the connecting plate 72 to move downwards via the first telescopic cylinder 71 during operation. At this time, the adsorption component 73 moves downwards synchronously. After the vacuum suction cup 733 contacts the top surface of the glass, the first telescopic cylinder 71 continues to drive the connecting plate 72 to move downwards. At this time, the vacuum suction cup 733 can be in close contact with the glass. If the connecting plate 72 moves downwards too far, the connecting plate 72 will squeeze the first spring 75. At this time, the connecting plate 72 will slide downwards along the vertical tube 731. After the vacuum suction cup 733 is close to the glass, the vacuum pump 77 can be activated to maintain a vacuum between the vacuum suction cup 733 and the inside of the vertical tube 731, at which time the glass can be adsorbed.

[0036] After the glass is placed between the first clamping plate 13 and the second clamping plate 16 at the upper end of the workbench 2, the second telescopic cylinder 19 drives the connecting block 20 to move forward, which causes the paddle 22 to push the force plate 18 forward. At this time, the connecting rod 17 drives the second rack 12 and the connecting rod 17 to move forward. When the second rack 12 moves, it drives the second gear 10 to rotate. The rotation of the second gear 10 causes the third rack 15 and the second clamping plate 16 to move backward. At this time, the first clamping plate 13 and the second clamping plate 16 can push the glass towards the middle. After the first clamping plate 13 and the second clamping plate 16 clamp the glass, the paddle 22 will continue to move forward and will be blocked by the force plate 18, rotating along the positioning rod 21. At this time, the rotation of the paddle 22 can... Passing through the bottom of the force plate 18, the lever 22 will be reset by the tension of the second spring 23 after passing through the force plate 18. At this time, when the connecting block 20 is reset by the second telescopic cylinder 19, the lever 22 will push the force plate 18 backward. After the force plate 18 is reset backward, the lever 22 can continue to move backward and rotate to move behind the force plate 18. This structure can facilitate the positioning of the glass. The outline position of the glass can be captured by the industrial camera 9. The first gear 57 can be rotated by the motor 56, so that the first gear 57 can roll along the first rack 6. At this time, the adsorption mechanism 7 can move synchronously. The movement of the adsorption mechanism 7 can be aligned with the glass. This structure can facilitate the alignment and calibration of the adsorption mechanism 7 with the glass.
