The sealing portion is attached to the lower end face of the stage body 1 provided with the groove 11, so that the air sealing groove 11 seals the face formed by the lower end face of the stage body 1, and of course, the air sealing is provided on the premise that the backlight unit 01 is placed on the upper end face of the stage body 1 and blocks all the holes 12 in the groove 11, so that the groove 11 and all the holes 12 in the groove 11 are blocked up and down by the backlight unit 01 and the sealing portion to form a closed cavity, after the vacuum equipment is opened, the air in the cavity is extracted, the air pressure in the cavity is reduced, and even the cavity is in a vacuum state.
The seal portion may be bonded to only a part of the lower end surface of the stage body 1 along the groove 11, and a seal portion having a size corresponding to the lower end surface of the stage body 1 may be bonded to the lower end surface of the stage body 1.
The upper end surface of the backlight unit 01 is exposed to the outside, part of the lower end surface of the backlight unit 01 is in contact with one end of all the holes 12, and the backlight unit 01 is tightly pressed on the stage body 1 by means of the air pressure difference between the upper end surface and the lower end surface of the backlight unit 01, so that the backlight unit 01 is fixed on the upper end surface of the stage body 1.
According to the characteristics of machining, the groove 11 on the lower end face of the platform body 1 is formed by milling, the hole 12 in the groove 11 is formed by drilling, and after the milling and drilling are completed, the sealing part is attached to the lower end face of the platform body 1, so that the lower end face of the groove 11 is sealed. Compared with the prior art in which a vacuum cavity is formed by directly drilling a vacuum hole, the vacuum cavity of the backlight unit group loading platform is formed by three parts, namely a milling groove 11, a drilling hole 12 and a pasting sealing part, the processing difficulty of each part is low, the operation is convenient and fast, the platform carrier body 1 cannot be broken, and the structural performance of the platform carrier body 1 is ensured.
The backlight unit group loading platform provided by the invention is further described below with reference to the accompanying drawings and the implementation mode.
The vacuum chamber is formed on the premise that the groove 11 and all the holes 12 thereof are hermetically sealed by the backlight unit 01 on the upper end surface of the stage body 1 and hermetically sealed by the sealing portion on the lower end surface of the stage body 1. It can be seen that the size of the backlight unit 01 is not smaller than the size of the largest area surrounded by all the holes 12.
In view of this feature, the stage body 1 may be provided with a plurality of spaced grooves 11, a plurality of holes 12 are provided in any one of the grooves 11, and each groove 11 and all the holes 12 in the groove 11 form an independent suction area for sucking the backlight unit 01 on the upper end surface of the stage body 1. Of course, the grooves 11 may form a suction area for sucking the backlight unit 01. For example, when the backlight units 01 have a plurality of sizes, the backlight unit 01 having the smallest size may be fixed by the suction area formed by one groove 11 and all holes 12 thereof, and the backlight unit 01 having a larger size may be fixed by the suction area formed by a plurality of grooves 11 and all holes 12 thereof.

Of course, only one vacuum apparatus may be provided, and when any one of the tanks 11 is used, the vacuum apparatus may be connected to any one of the tanks 11, and when a plurality of the tanks 11 are used, the vacuum apparatus may be connected to the plurality of the tanks 11 via a multi-way connection pipe.
Preferably, a plurality of vacuum devices are connected to the plurality of grooves 11 in a one-to-one correspondence manner, so that the specific air pressure value in each groove 11 can be independently controlled, and when one backlight unit 01 is simultaneously adsorbed by the plurality of grooves 11, the air pressure value in each groove 11 can be independently adjusted, thereby facilitating adjustment of the local pressure according to the specific structure of the backlight unit 01.
