The pump drive is operatively connected to drive the vacuum pump to produce a vacuum that is applied to the vacuum cup of the vacuum cup device.

A suction cup is provided, including: a cup body, including a sucking face, the cup body defining an axial direction perpendicular to the sucking face; a pump, connected to an end of the cup body opposite to the sucking face, the pump including a first passageway, a direction in which the first passageway extends and the axial direction forming an included angle therebetween; a movable handle, slidably disposed within the first passageway, including a piston.

A substrate transfer apparatus includes a body portion having a holding region on a surface thereof corresponding to a substrate. The body portion moves so that the surface thereof approaches the substrate up to at least a first distance. A plurality of vacuum holes are distributed in the holding region and form negative pressure to provide suction force to the substrate disposed at the first distance. At least some of the plurality of vacuum holes are disposed at equal intervals at an edge of the holding region and have the same width. A plurality of air holes are distributed in the holding region and form positive pressure to provide a buoyancy force to the substrate close to the holding region at a second distance smaller than the first distance.

In a laser irradiation apparatus 1 according to one embodiment, each of first and second flotation units 30a, 30b includes a base 31, and a porous plate 32 bonded to an upper surface of the base 31 by an adhesive layer 34, the base 31 includes a rising portion 312 protruding upward at an outer periphery facing at least the gap, and the porous plate 32 includes a cutout portion 321 configured to fit to the rising portion 312, and the adhesive layer 34 is formed along an inner wall of the rising portion 312 having fitted to the cutout portion 321.

The present disclosure provides a holding arrangement. The holding arrangement for holding a substrate includes: a body portion having a first side; a dry adhesive material provided on the first side of the body portion; a seal surrounding the dry adhesive material and configured to provide a vacuum region on the first side, wherein the dry adhesive material is provided in the vacuum region; and a conduit to evacuate the vacuum region.

A fabrication platform used for production lines of a display panel is provided. The fabrication platform includes: a jig, wherein the jig is configured to carry a glass substrate, and a plurality of via holes are defined on the jig; and an adsorption device, wherein the adsorption device includes a plurality of suction pads, the suction pads are disposed on a side of the jig away from the glass substrate and are disposed corresponding to the via holes, and the suction pads adsorb the glass substrate on the jig through the via holes. The provided fabrication platform effectively improves yield rate of the glass substrate in welding processes.

A display panel vacuum suction system includes a control device, a robot arm, and a vacuum device. The robot arm includes two or more retractable rods, and each of the retractable rods is connected with a vacuum plate. Each vacuum chamber is disposed in each of the vacuum plates, and each vacuum hole is disposed on a surface of each of the vacuum plates, wherein each vacuum chamber is connected with the vacuum device by a suction pipe. The control device controls expansion and retraction of the retractable rods of the robot arm, so that the vacuum plates connected with the retractable rods can be combined to pick up a single display panel or pick up two display panels respectively. By combining vacuum plates, and controlling the opening or closing of the vacuum holes of each of the vacuum plates, different sizes of display panels can be sucked.
