[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The present invention provides a movable fixing device. Figure 1 and Figure 2 As shown, the movable fixing device includes a first fixture 10 , a second fixture 20 , a first moving mechanism 30 and a second moving mechanism 40 .

[0023] The first fixture 10 is provided with a first bearing surface 11 and a first negative pressure hole 12 . The screen is supported by the first bearing surface 11 , and the screen is adsorbed and fixed on the first bearing surface 11 through the first negative pressure hole 12 .

[0024] The first moving mechanism 30 includes a first driver 31, a first pushing block 32, and a second pushing block 33. At least one of the first pushing block 32 and the second pushing block 33 has a guide slope 34. In this embodiment, the guide slope 34 is provided on the second pushing block 33, and the first pushing block 32 is a roller.

[0025] The first driver 31 is connected to the first push block 32 to drive the first push block 32 to move laterally. The second push block 33 is connected to the first fixture 10. The first push block 32 and the second push block 33 are in driving contact with each other, so that when the first push block 32 moves laterally, the second push block 33 and the first fixture 10 move longitudinally. The first driver 31 is preferably a pneumatic cylinder.

[0026] The screen is placed on the first jig 10 and the screen is adsorbed by negative pressure. When the position of the screen needs to be adjusted, the first driver 31 works to control the movement of the first pushing block 32, thereby changing the position of the first pushing block 32. Under the action of the guide slope 34, the second pushing block 33 will move longitudinally due to the push of the first pushing block 32 or due to its own gravity. On the one hand, the longitudinal movement of the first jig 10 can be achieved by the first driver 31. On the other hand, the first driver 31 can be placed horizontally to minimize the longitudinal height of the fixing device to facilitate the installation of the fixing device on the machine. The utility model can be used to complete the position fine-tuning action to facilitate the fine alignment of the screen and the cover glass.

[0027] The second fixture 20 is provided with a second supporting surface 21 and a second negative pressure hole 22. The screen is supported by the second supporting surface 21, and the screen is fixed to the second supporting surface 21 by suction through the second negative pressure hole 22. In this embodiment, the first fixture 10 is provided with a receiving groove 13, and the second fixture 20 is placed in the receiving groove 13.

[0028] The first driver 31 is installed below the first fixing plate 51 , and the second fixture 20 is installed above the first fixing plate 51 .

[0029] The second jig 20 and the first jig 10 are two independent jigs. Before the screen and cover glass are bonded together, the first jig 10 and the second jig 20 simultaneously absorb and secure the screen to align the cover glass and screen. After alignment is complete, the second jig 20 absorbs and secures the screen. Then, the first driver 31 is activated to move the first jig 10 longitudinally relative to the second jig 20. The first jig 10 drives the screen longitudinally to complete the pre-bonding process with the cover glass. During the bonding process, the second jig 20 maintains the screen and cover glass in a well-aligned position, allowing the first jig 10 to complete the precise bonding process.

[0030] The area of ​​the second bearing surface 21 is preferably smaller than that of the first bearing surface 11 . When the screen and the cover glass are in contact, most of the screen can be bonded to the cover glass through the second fixture 20 .

[0031] The second moving mechanism 40 includes a second driver 41 and a second fixing plate 42. The first fixing plate 51 is mounted above the second fixing plate 42. The first driver 31 is mounted in the space between the first fixing plate 51 and the second fixing plate 42. The second driver 41 is used to drive the second fixing plate 42 to move perpendicular to the longitudinal direction. Specifically, the second driver 41 is used to drive the second fixing plate 42 to move in the transverse direction. The second moving mechanism 40 can significantly change the planar position of the first fixture 10 and the second fixture 20. The second driver 41 can be a motor and screw structure.

[0032] The second moving mechanism 40 further includes a first slider 43 and a first slide rail 44 . The first slider 43 is slidably connected to the first slide rail 44 . The first slider 43 is connected to the second fixing plate 42 .

[0033] The first moving mechanism 30 further includes a second slider 35 and a second slide rail 36 . The second slider 35 is slidably connected to the second slide rail 36 . The first driver 31 is connected to the second slider 35 . The first pushing block 32 is disposed on the second slider 35 .

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
