Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal panel transfer, and in particular to a liquid crystal panel transfer device. Background Art

[0002] The quality of a TV depends first on its panel, because the quality of the panel directly affects the viewing effect of the picture, and the LCD TV panel accounts for more than half of the cost of the whole machine, which is the main factor affecting the cost of LCD TV. Therefore, the LCD panel needs to be prevented from bumping during the transfer process.

[0003] After searching, the existing patent (publication number: CN208499746U) discloses a suction cup clamp, including a long strip-shaped clamp body, a plurality of negative pressure suction cups arranged along the extension direction of the clamp body are fixedly arranged below the clamp body, and a plurality of short rods are also arranged at intervals on the clamp body, and the extension direction of the short rods is perpendicular to the extension direction of the clamp body. A negative pressure suction cup is fixedly arranged below each end of each short rod, and the air paths of all the negative pressure suction cups fixed on the clamp body are connected and constitute a first suction cup group, and the air paths of all the negative pressure suction cups fixed on the short rods are connected and constitute a second suction cup group, and a adapter block connected to the robot is fixedly arranged above the clamp body. The suction cup clamp of the utility model has two independently controlled first suction cup groups and second suction cup groups, which can alternately clamp sheet metal parts of different sizes, save production space, simplify the process, improve production efficiency, and reduce production costs. In the process of realizing this application, the inventor found that the prior art has the following problems: Most of the existing suction cup clamps are connected to mechanical arms for use. They are too large and inconvenient to move. They are mostly used on production lines and cannot enter small spaces such as elevators. They are not suitable for transferring and installing LCD panels. Some split handheld suction cup clamps require the cooperation of multiple people to transfer and move some slightly larger LCD panels. In addition, due to the excessive weight of the LCD panels, the workers' physical strength is consumed during transportation, and they are prone to bumps and damage during transportation.
