In some embodiments, the plurality of holes 20 are arranged in an array, and the plurality of adsorption holes 11 are disposed around the holes 20 and arranged in an array. Specifically, the tray body 10 is rectangular, wherein, as shown in fig. 1, the first direction X is along the length direction of the tray body 10, the second direction Y is along the width direction of the tray body 10, and the first direction X and the second direction Y are perpendicular to each other. It can be understood that the plurality of through holes 20 are arranged in a plurality of ways, for example, the plurality of through holes 20 may be disposed only along the first direction X, only along the second direction Y, or both along the first direction X and the second direction Y, for example, the through holes 20 may be in a shape of "one", "ten", "tian" -shape, grid, or other matrix, and the like. Of course, the hollow holes 20 may be distributed along the diagonal line of the tray body 10, etc., and are not particularly limited herein.

The plurality of adsorption holes 11 are disposed around the hollow holes 20, and correspondingly, the plurality of adsorption holes 11 may be disposed only along the first direction X, only along the second direction Y, or both along the first direction X and the second direction Y, for example, the adsorption holes 11 may be in a shape of "one", "cross", "field", "grid", or other matrix, etc. Of course, the adsorption holes 11 may also be distributed along the diagonal line of the tray body 10, etc., and are not particularly limited herein.

In some embodiments, the number of the cavities 12 is plural, the plural cavities 12 extend along the first direction X and/or the second direction Y, respectively, and the plural adsorption holes 11 are arranged at intervals along the first direction X and/or the second direction Y, wherein the first direction X and the second direction Y intersect.

Specifically, as shown in fig. 4, taking the tray body 10 as a rectangle, the first direction X is along the length direction of the tray body 10, the second direction Y is along the width direction of the tray body 10, and the first direction X and the second direction Y are perpendicular to each other. It is understood that the plurality of cavities 12 may extend along only the first direction X, may extend along only the second direction Y, or may intersect both the first direction X and the second direction Y.

Illustratively, the cavity 12 includes a first cavity 121 and a second cavity 122, the plurality of first cavities 121 extend along a first direction X, the plurality of second cavities 122 extend along a second direction Y, adjacent first cavities 121 are arranged at intervals, a hollow hole 20 is arranged between adjacent first cavities 121, the first cavities 121 and the second cavities 122 extend along the first direction X and the second direction Y respectively to form an air channel, and the first cavities 121 and the second cavities 122 intersect inside the tray body 10, so that all the first cavities 121 and all the second cavities 122 are communicated with each other, which is beneficial to improving the negative pressure suction efficiency.

In some embodiments, each adsorption hole 11 has a diameter ranging from 0.5mm to 5mm, and a distance between adjacent adsorption holes 11 ranges from 10mm to 30 mm.

It can be understood that, at a certain area of the tray body 10, the larger the diameter of the suction hole 11 is, the larger the suction force of the suction hole 11 to the flexible display device 200 is, and conversely, the smaller the diameter of the suction hole 11 is, the smaller the suction force of the suction hole 11 to the flexible display device 200 is. It can be understood that the larger the adsorption capacity of the adsorption holes 11 is, but when the diameter of the adsorption holes 11 is too large, the flexible display device 200 may form a depression under the action of the adsorption force of the adsorption holes 11, thereby affecting the yield of the flexible display device 200; and the adsorption capacity of the adsorption holes 11 is too small, adsorption efficiency may be lowered.

Similarly, the distance between the suction holes 11 represents the distribution density of the suction holes 11 on the surface of the tray body 10, and the distribution of the suction holes 11 on the surface of the tray body 10 is more sparse if the distance between the plurality of suction holes 11 is larger for the same diameter of the suction holes 11, whereas the distribution of the suction holes 11 on the surface of the tray body 10 is more dense if the distance between the plurality of suction holes 11 is smaller for the same diameter of the suction holes 11. It can be understood that the more densely the adsorption holes 11 are distributed on the surface of the tray body 10, certain influence may be exerted on the structural strength of the tray body 10, which is not favorable for the structural stability of the tray body 10. The distribution of the adsorption holes 11 on the surface of the tray body 10 is too sparse, and the adsorption capacity of the adsorption holes 11 is too small, which may reduce the adsorption efficiency.

Illustratively, the diameter of each adsorption hole 11 may be 0.5mm, 3mm, 5mm, or the like, and the distance between the adsorption hole 11 and the adsorption hole 11 may be 10mm, 20mm, 30mm, or the like. Through the diameter with every adsorption hole 11 and the interval setting of adsorption hole 11 in suitable scope, on the basis of guaranteeing the adsorption efficiency of adsorption hole 11, both can improve adsorption efficiency, can guarantee the structural stability of turnover tray 100 again.

In addition, different adsorption hole 11 diameters and different adsorption hole 11 intervals also can play the effect that is suitable for the turnover tray 100 of equidimension not for turnover tray 100 can be used on the flexible substrate of equidimension not, improves turnover tray 100's commonality.

In some embodiments, the minimum distance of the adsorption hole 11 from the edge of the tray body 10 ranges from 1mm to 2 mm. During the use, flexible display device 200 can flush with the border of tray body 10, in order to guarantee that flexible display device 200 covers adsorption hole 11 completely, be provided with certain distance between the border of adsorption hole 11 and tray body 10 to be favorable to improving the utilization ratio of turnover tray 100, this distance minimum can be for example 1mm or 2mm, is certainly greater than 2 mm's distance and also can realize that flexible display device 200 covers adsorption hole 11 completely, does not do specific restriction here.

In some embodiments, the tray body 10 is made of carbon fiber or light metal. The light metal material can be aluminum alloy, titanium alloy, magnesium alloy or magnesium aluminum alloy and the like, and has the characteristics of small relative density, high strength, high corrosion resistance and the like, and the carbon fiber and the light metal material have the advantages of light weight, high stability, firmness, low deformation possibility and the like, so that the light weight of the structure of the turnover tray 100 is realized while the structural strength of the turnover tray 100 is ensured.

In some embodiments, as shown in fig. 5, a plurality of connection ports 13 are provided at intervals on at least one side surface of the tray body 10, and the connection ports 13 communicate with the cavity 12. The side surface is provided with the connecting port 13, so that the processing and manufacturing of the cavity 12 in the tray body 10 are facilitated. The number of the connecting ports 13 may be set corresponding to the number of the cavities 12, for example, the number of the connecting ports 13 may be one, or may be multiple, and when the number of the interfaces is multiple, the connecting ports 13 may be all set on one side surface of the tray body 10, or may be set on two adjacent side surfaces of the tray body 10, respectively.

In some embodiments, the connection port 13 includes a first connection port 131, and the first connection port 131 is disposed on at least one side surface of the tray body 10. As shown in fig. 6, the pallet body 10 further comprises at least one pipe joint 30. The pipe joint 30 is detachably connected to an inner wall of the first connector 131, and the pipe joint 30 may be connected to the first connector 131 by screwing, clamping, or the like. The tray body 10 can be connected with the external negative pressure source 50 through the first connection port 131, so that the cavity 12 forms the negative pressure. The first connection ports 131 correspond to the pipe joints 30 one to one, and the arrangement of the pipe joints 30 on the tray body 10 is not described again.

In some embodiments, as shown in fig. 7, the epicyclic tray 100 further comprises a negative pressure source 50 and a negative pressure control switch 60.

The negative pressure source 50 is communicated with the pipe joint 30, wherein the negative pressure source 50 may be a vacuum pump for forming a negative pressure in the cavity 12 by connecting the pipe joint 30, so that the adsorption hole 11 can perform an adsorption function. Negative pressure control switch 60 is used for controlling opening and closing of negative pressure source 50, when the flexible display device 200 of treating processing is placed on turnover tray 100, open through control negative pressure control switch 60, thereby realize that flexible display device 200 adsorbs on turnover tray 100, after flexible display device 200 finishes processing and shifts to next manufacturing procedure through turnover tray 100, close through control negative pressure control switch 60, cavity 12 resumes atmospheric pressure balance, thereby can separate flexible display device 200 from turnover tray 100, continue to carry out the manufacturing of flexible display device 200.

In some embodiments, the connection port 13 further includes a second connection port 132, the first connection port 131 and the second connection port 132 are spaced apart from each other on at least one side of the tray body 10, and the first connection port 131 is in communication with the second connection port 132. In the embodiment of the present invention, the cavity 12 is formed in the tray body in order to form the gas channel for vacuum suction, and the cavity 12 is formed by hollowing out the side surface of the tray body 10 into the tray body 10, so that the connection port 13 is formed in the side surface of the tray body 10.

When the first cavity 131 and the second cavity 132 are provided at the same time, it can be understood that the first connection port 131 is formed at the side of the tray body 10 when the first cavity 131 is formed inside the machining tray body 10, and the second connection port 132 is formed at the side of the tray body 10 when the second cavity 132 is formed inside the machining tray body 10. Specifically, the second connection ports 132 and the first connection ports 131 may be respectively disposed on two sides adjacent to the tray body 10, and of course, the first connection ports 131 and the second connection ports 132 may also be disposed on one side or a plurality of sides of the tray body 10 at intervals, which is not particularly limited herein.

As shown in fig. 6, the tray body 10 further includes a sealing member 40, and the sealing member 40 seals the second connection port 132, wherein the sealing member 40 may be a plug, a sealant, or the like, and since the first connection port 131 is used to connect the negative pressure source 50 so as to form negative pressure inside the cavity 13, the second connection port may not need to be connected to the negative pressure source 50 again because the first cavity 121 and the second cavity 122 are communicated, thereby saving cost. Therefore, in order to ensure the formation of the negative pressure inside the first cavity 121 and the second cavity 122, the second connection port 132 is only required to be blocked to seal the cavity 12, so as to prevent air leakage of the cavity 12 in the process of forming the negative pressure, and ensure the adsorption capacity of the turnover tray 100 on the flexible display device 200. The second connection ports 132 correspond to the sealing members 40 one by one, so the arrangement of the sealing members 40 on the tray body 10 is not described again.
