[0024] Embodiment 1: As shown in the attached drawings, a loading device for an LCD panel includes a base 1 and a conveying assembly 2. The conveying assembly 2 is installed on the top of the base 1, and further includes a feeding assembly for feeding the LCD to be dispensed.

[0025] In this embodiment, specifically, the feeding assembly includes a guide plate 3, a slide plate 4, a guide groove 5, a chute 6, a lifting rod 7, a suction and release assembly, and a driving assembly. The guide plate 3 is fixedly connected to the top of the base 1. The slide plate 4 is slidably connected to the guide plate 3. The guide groove 5 is opened on the guide plate 3. The chute 6 is opened on the slide plate 4. The lifting rod 7 is slidably connected between the guide groove 5 and the chute 6. The suction and release assembly is used to control the suction rod to suck and release the LCD panel. The driving assembly is used to drive the slide plate 4 to move and drive the suction rod to feed the LCD. Among them, the guide groove 5 is L-shaped, and the chute 6 is inclined. Both the upper and lower sides of the slide plate 4 are inclined planes.

[0026] Furthermore, the suction and release assembly includes an electric driving device 8, a suction cup body 9, a button 10, and an elastic member 101. The electric driving device 8 is fixedly connected to the end of the lifting rod 7. The suction cup body 9 is installed at the output end of the electric driving device 8. The button 10 is installed on the guide plate 3. The button 10 is electrically connected to the electric driving device 8. The elastic member 101 is connected between the button 10 and the guide plate 3.

[0027] Furthermore, the driving assembly includes a support block 11, a motor 12, a support rod 13, a rotating shaft 14, a fixed rod 15, a rotating rod 16, and a connecting rod 17. The support block 11 is fixedly connected to the top of the base 1. The motor 12 is installed on the top of the support block 11. The support rod 13 is fixedly connected to the top of the base 1. The rotating shaft 14 is rotatably connected to the support rod 13. The fixed rod 15 is fixedly connected to the top of the base 1. The rotating rod 16 is rotatably connected to the fixed rod 15. The end parts of the rotating shaft 14 are connected to the output shaft of the motor 12 and the rotating rod 16 through couplings respectively. The connecting rod 17 is rotatably connected between the slide plate 4 and the rotating rod 16.

[0028] Even further, it further includes a plurality of material blocking strips 18 and a material guiding plate 19. The plurality of material blocking strips 18 are fixedly connected to the conveying assembly 2. The material guiding plate 19 is fixedly connected to the side of the conveying assembly 2. Among them, the material guiding plate 19 is inclined.

[0029] Further, it further includes a dispensing component for automatically dispensing the LCD. Specifically, the dispensing component includes a mounting bracket 20 and a dispenser 21. The mounting bracket 20 is installed on top of the conveying component 2, and the dispenser 21 is installed inside the mounting bracket 20.

[0030] The LCD is placed on top of the base 1 and below the suction cup body 9. Subsequently, the motor 12 and the electric drive device 8 are started. The motor 12 drives the rotating rod 16 to rotate through the rotating shaft 14, and then drives the slide plate 4 to move left and right through the connecting rod 17. At the same time, the lifting rod 7 and the suction rod are driven to move left and right. Under the action of the guiding groove 5 and the sliding groove 6, the lifting rod 7 moves up and down in the guiding groove 5, thereby driving the electric drive device 8 and the suction cup body 9 to move up and down, so that the suction cup body 9 can adsorb the LCD onto the conveying component 2. As the lifting rod 7 moves, when the lifting rod 7 contacts the button 10, the lifting rod 7 presses the button 10, and the elastic member 101 is compressed. The button 10 then controls the electric drive device 8 to close, thereby controlling the suction cup body 9 to stop adsorbing the LCD, and then the LCD falls onto the conveying component 2, enabling the conveying component 2 to convey the LCD. When the lifting rod 7 moves to separate from the button 10, the elastic member 101 resets, driving the button 10 to reset, and then controlling the electric drive device 8 to restart, facilitating the suction cup body 9 to adsorb the next LCD. In this way, self-absorption and self-discharging can be achieved, with simple operation and high efficiency. Subsequently, under the action of the baffle strip 18, the LCD can be aligned and moved, facilitating subsequent dispensing.

[0031] The above is only an illustration of the best embodiment of the present invention, but it should not be construed as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure allows changes. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
