[0036] A screen laminating device 1000, which includes a first frame 1100 and an outer screen calibration mechanism 1200, an inner screen calibration mechanism 1300, and a first manipulator 1400 disposed on the first frame 1100. The outer screen calibration mechanism 1200 is used to place the outer screen and calibrate the position of the outer screen. The inner screen calibration mechanism 1300 is used to place the inner screen and calibrate the position of the inner screen. The first manipulator 1400 is used to grab the outer screen located on the outer screen calibration mechanism 1200 and laminate it with the inner screen on the inner screen calibration mechanism 1300 to form a semi-finished display screen;

[0037] A vacuum pressure maintaining device 2000, which includes a second frame 2100 and a second manipulator 2200 and at least one vacuum mechanism 2300 disposed on the second frame 2100. The second manipulator 2200 is used to grab the semi-finished display screen located on the inner screen calibration mechanism 1300 and place it into the vacuum mechanism 2300.

[0038] Among them, the first frame 1100 and the second frame 2100 can be separately provided, such as detachably connected, or can be integrally provided. The outer screen calibration mechanism 1200 is used to calibrate the position of the outer screen. The specific calibration method can be to limit the outer screen at a preset position by means of horizontal movement, so as to facilitate the grabbing of the first manipulator 1400. The inner screen calibration mechanism 1300 is used to calibrate the position of the inner screen. The specific calibration method can be to adjust the position and placement angle of the inner screen by means of horizontal movement and horizontal rotation, so as to facilitate the first manipulator 1400 to accurately laminate the outer screen on the inner screen. The first manipulator 1400 can adopt a conventional form, such as a gantry manipulator or a multi-axis manipulator. The specific method of grabbing the outer screen can be vacuum adsorption, and of course, it can also be in a clamping manner. The placement methods of the outer screen and the inner screen can be manual placement or automatic placement by means of a manipulator.

[0039] The second manipulator 2200 can adopt a conventional form, such as a gantry manipulator or a multi-axis manipulator. The specific way to grasp the semi-finished product screen can be vacuum adsorption, or it can also be a clamping method, so as to facilitate grasping the semi-finished product screen into the vacuum mechanism 2300. At this time, the outer screen and the inner screen have a certain bonding ability, and the inner screen and the outer screen will not separate during the transfer of the second manipulator 2200. The vacuum mechanism 2300 can adopt a conventional form, such as cooperating with an openable and closable box body to evacuate the air, so as to facilitate the outer screen and the inner screen of the semi-finished product screen to fit more closely under vacuum conditions.

[0040] In this embodiment, the position of the outer screen is automatically calibrated by the outer screen calibration mechanism 1200 and the position of the inner screen is calibrated by the inner screen calibration mechanism 1300, so as to facilitate the first manipulator 1400 to accurately place the outer screen on the inner screen to form a semi-finished product screen. Then, the second manipulator 2200 is used to place the semi-finished product screen in the vacuum mechanism 2300, and the outer screen and the inner screen are tightly bonded together by vacuum negative pressure to form a finished product screen, thereby improving the bonding accuracy of the outer screen and the inner screen, and the automatic transfer by the manipulator is also beneficial to improving the production speed.

[0041] In a preferred embodiment, such as Figure 4 and Figure 5As shown, preferably, the outer screen calibration mechanism 1200 includes a first driving member 1210 and a first automatic calibration seat 1220. The first driving member 1210 is disposed on the first rack 1100 and is used to drive the first automatic calibration seat 1220 to move below the loading point of the first manipulator 1400. The first automatic calibration seat 1220 includes a first bearing plate 1221 connected to the output end of the first driving member 1210 and a horizontal clamping assembly 1222 disposed on the first bearing plate 1221. The first bearing plate 1221 has a first placement position 1223 for placing the outer screen, and the horizontal clamping assembly 1222 is used to position the outer screen located at the first placement position 1223. Among them, the first driving member 1210 is preferably a linear module to facilitate precise control of the movement of the first automatic calibration seat 1220. The two ends of the linear module are the outer screen loading position and the outer screen unloading position. The outer screen loading position is used to place the outer screen on the first automatic calibration seat 1220, and the outer screen unloading position is the loading position of the first manipulator 1400, which facilitates the first manipulator 1400 to grab the outer screen located on the first automatic calibration seat 1220. The first placement position 1223 on the first bearing plate 1221 may be a cavity adapted to the size of the outer screen, and the horizontal clamping assembly 1222 may adopt the form of a cylinder + chuck. A plurality of chucks are arranged around the circumference of the first placement position 1223, and a plurality of cylinders are used to drive the plurality of chucks to horizontally move towards the first placement position 1223 respectively, so as to accurately position the outer screen within the first placement position 1223. Two fixed stoppers may also be provided on the first bearing plate 1221 around the circumference of the first placement position 1223. At this time, there are two chucks. One fixed stopper is disposed opposite to one chuck, and the other fixed stopper is disposed opposite to the other chuck. Moreover, the two chucks and the two fixed stoppers are all arranged around the circumference of the first placement position 1223. By driving the two chucks to move towards the corresponding fixed stoppers with two cylinders, the positioning of the outer screen on the first placement position 1223 can be achieved. Compared with the previous method, this method is beneficial to reducing the number of cylinders and lowering the cost. In this embodiment, the horizontal clamping assembly 1222 positions the outer screen located at the first placement position 1223 and releases the outer screen after positioning, so as to facilitate the first manipulator 1400 to grab the outer screen.

[0042] In a preferred embodiment, as Figure 6 and Figure 7As shown, preferably, the inner screen calibration mechanism 1300 includes a second driving member 1310 and a second automatic calibration seat 1320.

The second automatic calibration seat 1320 includes a UVW alignment platform 1321 connected to the output end of the second driving member 1310 and a second bearing plate 1322 disposed on the output end of the UVW alignment platform 1321.

Among them, the second driving member 1310 is preferably a linear module to facilitate precise control of the movement of the second automatic calibration seat 1320. The two ends of the linear module are the inner screen loading position and the screen fitting position. The inner screen loading position is used to place the inner screen on the second automatic calibration seat 1320, and the screen fitting position is the blanking position of the first manipulator 1400, so as to facilitate the first manipulator 1400 to fit the outer screen on the inner screen. The second placement position 1323 fixes the inner screen by providing vacuum adsorption holes 1324. When the inner screen is placed on the second placement position 1323, the inner screen is fixed by means of vacuum adsorption to prevent the inner screen from moving during calibration and attachment. In addition, the UVW alignment platform 1321 can adopt a conventional form, that is, the UVW alignment platform 1321 can drive the second bearing plate 1322 to move horizontally and rotate around the vertical direction to facilitate adjusting the position and placement angle of the inner screen on the second placement position 1323. In this embodiment, after the UVW alignment platform 1321 adjusts the position and placement angle of the inner screen on the second placement position 1323, the second driving member 1310 can be used to drive the inner screen to move to the blanking point of the first manipulator 1400, so as to facilitate the first manipulator 1400 to fit the outer screen on the inner screen. In addition, a vacuum button and a first start button can be provided on the second frame 2100. Since the first inner screen is self-adhesive with a protective film, after the inner screen is manually placed on the second placement position 1323 first, the inner screen is adsorbed on the second placement position 1323 through the vacuum button. After the protective film is removed manually, the UVW alignment platform 1321 can be automatically used to calibrate the inner screen through the first start button.
