As shown in fig. 1, a conventional transfer platform 90 for transferring a glass substrate 99 includes an adsorption plate 91, a plurality of vacuum suction nozzles 92 are mounted on the adsorption plate 91, the transfer platform 90 lifts the glass substrate 99 and transfers the glass substrate after being adsorbed by the vacuum suction nozzles 92 on the adsorption plate 91, and a direction of an arrow in fig. 1 indicates a transfer direction of the glass substrate 99. Because the size and weight of the glass substrate 99 are increased, if the current carrying mode is still used, the glass substrate 99 is easy to be damaged or the quality is abnormal due to too large friction; meanwhile, in the conveying process, because one adsorption plate 91 is arranged to convey one glass substrate 99, the two sides of the glass substrate 99 can be subjected to resistance of different degrees due to the structural difference of the transfer platform, and the positions of the two sides deviate, so that the next-stage process can be influenced.

Therefore, there is a need for a new transfer platform and transfer device that overcomes the problems of the prior art.

Example 1

Referring to fig. 2, a first embodiment of the present invention provides a transfer platform 10, which includes an adsorption plate 1 for supporting and adsorbing a substrate 20, wherein the adsorption plate 1 is provided with a plurality of vacuum nozzles 11 and at least one vacuum chuck 12, and an adsorption area of the vacuum chuck 12 is larger than an adsorption area of the vacuum nozzles for increasing a force-bearing area for adsorbing the substrate 20. The vacuum suction disc 12 can prevent the situation that when the substrate 20 is sucked by the vacuum suction nozzle 11 with small holes on the suction plate 1, the required pressure value is increased due to the small stress of the unit area, and the substrate 20 is not pulled easily due to the small stress area.

In this embodiment, the opening of the vacuum chuck 12 and the opening of the vacuum nozzle 11 are located in the same plane. This makes the opening of the vacuum chuck 12 and the opening of the vacuum nozzle 11 flush with the surface of the substrate 20 to be sucked, and can better suck the substrate 20 and prevent the generation of tensile stress due to the difference in height.

In this embodiment, the opening of the vacuum chuck 12 is circular, the diameter of the circular opening of the vacuum chuck 12 is 1cm to 5cm, preferably 2cm, 3cm, or 4cm, the opening of the vacuum chuck 12 is larger than the opening of the vacuum nozzle 11, and the vacuum chuck 12 can increase the force-bearing area for absorbing the substrate 20, so as to absorb the substrate 20 well.

In this embodiment, the adsorption plate 1 is rectangular, and the adsorption plate 1 is divided into a first region 101 and a second region 102 along the length direction; the number of the vacuum suction cups 12 is two, and the two vacuum suction cups 12 are respectively located in the middle of the first area 101 and the second area 102. The paired arrangement of the vacuum chucks 12 can firmly suck the substrate 20 and prevent the substrate 20 from being rotationally displaced.

In this embodiment, the vacuum suction cups 12 located in the first area 101 and the second area 102 are aligned with the center point of the vacuum suction nozzle 11. Therefore, the appearance is attractive, a concentrated pressure area is conveniently formed on a straight line when the substrate 20 is adsorbed, and the substrate 20 can be better adsorbed.

This arrangement enables both the vacuum chuck 12 and the vacuum nozzle 11 to be attached to the surface of the substrate 20 to be sucked, and the substrate 20 to be sucked.

In this embodiment, the second through hole 22 is in a strip shape and extends along the width direction of the adsorption plate 1. Because the adsorption plate 1 drives the moving direction of the substrate 20 to be the length direction of the adsorption plate 1, the second through hole 22 is arranged in a pressure area capable of forming a line segment in the moving direction of the substrate 20, so that the substrate 20 can be better adsorbed and driven to move.

In this embodiment, the length of the second through hole 22 is equal to the diameter of the first through hole 21.

In this embodiment, the vacuum chuck 12 protrudes from the adsorption plate 1, and the thickness of the buffer rubber pad 2 is equal to the height of the vacuum chuck 12 protruding from the adsorption plate 1. Thus, the second through hole 22 of the cushion rubber pad 2 serves as an opening of the vacuum suction nozzle 11, so that the opening of the vacuum suction cup 12 and the opening of the vacuum suction nozzle 11 are positioned in the same plane, the substrate 20 can be better adsorbed, and the tensile stress generated by the height difference can be prevented.

Referring to fig. 4 and 5, the present invention further provides a conveying device 100, which includes at least two of the transfer platforms 10, a mounting frame 30 and a suction pipe (not shown); the mounting frame 30 is arranged on the side of the transfer platform 10 facing away from the base plate 20; the transfer platforms 10 are symmetrically and fixedly connected to the mounting frame 30, and are used for driving the transfer platforms 10 and the substrates 20 to move, uneven stress on the substrates 20 is reduced by arranging the transfer platforms 10 in pairs, and abnormal deviation of two sides of the substrates 20 is avoided; the moving direction of the substrate 20 is indicated by arrows in fig. 4 and 5; the air suction pipe is communicated with the vacuum suction nozzle 11 and the vacuum suction disc 12 of the transfer platform 10, and is used for sucking air to enable the vacuum suction nozzle 11 and the vacuum suction disc 12 to generate suction negative pressure.
