[0037] The utility model provides a curved screen laminating machine through improvement. The technical solution of the utility model is:

[0038] like Figure 1 As shown,

[0039] A curved screen laminating machine comprises a frame 1, and also comprises: an inner screen feeding mechanism 2, an inner screen moving mechanism 3, a visual inspection mechanism 4 and a screen laminating mechanism 5 arranged on the frame 1.

[0040] like Figure 5As shown, the inner screen feeding mechanism 2 includes a first translation component 21 and a first inner screen seat 22 that are fixedly connected, and the first translation component 21 drives the first inner screen seat 22 to translate. The first translation component 21 is used to drive the first inner screen seat 22 to translate for feeding and position adjustment. In some embodiments, the first translation component 21 can be a linear slide rail.

[0041] like Figure 2 As shown, the inner screen moving mechanism 3 includes a second translation component 31, a lifting component 32, a rotating component 33 and a first suction head 34 connected in sequence. The second translation component 31 is used to drive the lifting component 32, the rotating component 33 and the first suction head 34 to translate, move the inner screen and adjust the position of the inner screen; the lifting component 32 is used to drive the rotating component 33 and the first suction head 34 to move up and down, move the inner screen; the rotating component 33 is used to drive the first suction head 34 to rotate, and adjust the angle of the inner screen. The moving path of the second translation component 31 is perpendicular to the moving path of the first translation component 21. The translation of the inner screen at various positions on the horizontal plane is achieved through the first translation component 21 and the second translation component 31.

[0042] like Figure 1 and Figure 6 As shown, the visual inspection mechanism 4 is fixedly connected to the inner screen moving mechanism 3. The visual inspection mechanism 4 is used to capture information such as the position and angle of the inner and outer screens, and then transmit the information to the computer device for comparison and identification, and then return the information to the inner screen feeding component and the inner screen moving component, and adjust the position of the inner screen according to the position of the outer screen, so that the outer screen can be more accurately attached to the inner screen.

[0043] like Figure 3 As shown, the screen-attaching mechanism 5 comprises an outer screen seat 51, a first driving device 52 and a second inner screen seat 53. The first driving device 52 drives the outer screen seat 51 to rotate and cover the second inner screen seat 53. The first driving device 52 may be a motor, which drives the outer screen seat 51 to rotate, so that the outer screen seat 51 covers the second inner screen seat 53, thereby making the inner screen and the outer screen attached together.

[0044] like Figure 4As shown, an inner screen lifting mechanism 6 is provided under the second inner screen seat 53, and the inner screen lifting mechanism 6 is used to lift the inner screen in the second inner screen seat 53 so that the inner screen and the outer screen can be further fitted. The inner screen lifting mechanism 6 includes a second driving device 61 and a top plate 62. The second driving device 61 drives the top plate 62 to rise and fall. The second driving device 61 can be a cylinder, and the top plate 62 is lifted or retracted by the push rod of the cylinder to realize the lifting of the inner screen. The top plate 62 and the bottom surface of the second inner screen seat 53 are detachably connected, and different types of top plates 62 can be replaced according to different inner screens.

[0045] When in use, firstly, the inner screen and the outer screen are loaded manually or by an external robot arm, and the inner screen is placed on the first inner screen seat 22, and the outer screen is placed on the outer screen seat 51. Then, the second translation component 31 drives the visual inspection mechanism 4 to translate, and the inner screen and the outer screen are photographed. After the photographing, the position of the inner screen is adjusted by the first translation component 21, and the position of the first suction head 34 is adjusted by the second translation component 31 and the rotation component 33. After the adjustment is completed, the first suction head 34 is lowered by the lifting component 32, and the first suction head 34 sucks up the inner screen, and then moves the inner screen to the second inner screen seat 53. Then, the first driving device 52 drives the outer screen seat 51 to rotate, and the outer screen is attached to the inner screen, and the screen bonding is completed.

After the inner screen and the outer screen are attached, when the outer screen seat 51 and the second inner screen seat 53 are separated, the stickiness of the two is greater than the stickiness of the first adhesive member 512 and the second adhesive member 531, and the inner screen and the outer screen will not be separated. The viscosity of the second adhesive member 531 is greater than that of the first adhesive member 512. By setting the viscosity of the second adhesive member 531 to be greater than that of the first adhesive member 512, when the inner screen and the outer screen are bonded together and then cut into pieces, the combination of the two will remain on the second inner screen seat 53, making cutting easier.
