In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0068] like Figures 1 to 19 As shown, a preferred embodiment of an automated display assembly system of the present invention includes a conveyor belt 1. A main display assembly station a, an LCD screen assembly station b, and a cover assembly station 3c are sequentially arranged around the conveyor belt 1 along the conveyor belt 1 conveyor belt 1. A base assembly station 2c is also provided at the LCD screen assembly station b.

[0069] like Figure 2 As shown, the main display loading station a includes a material bin 2a, a main display installation station 3a, and a main display loading station 4a. The main display loading station 4a, the main display installation station 3a, and the material bin 2a are arranged sequentially on one side of the belt conveyor 1 according to the material assembly sequence.

[0070] like Figure 3 and Figure 4 As shown, the hopper 2a provides materials and transfers them to the main display installation station 3a. The hopper 2a includes a frame 21a, a tray conveying assembly 22a, a tray lifting assembly 23a, a three-axis gantry slide 24a, and a loading robot 25a. The tray conveying assembly 22a is horizontally arranged and installed on the frame 21a, the tray lifting assembly 23a is vertically arranged and installed on the frame 21a, the three-axis gantry slide 24a is mounted on the top of the frame 21a, and the loading robot 25a is installed on the three-axis gantry slide 24a for gripping and transferring materials.

[0071] In this embodiment, the hopper 2a uses a receiving tray 5a to hold materials, which are then transferred by the tray conveying assembly 22a. In this embodiment, the hopper 2a includes two tray conveying assemblies 22a and two tray lifting assemblies 23a. The two tray conveying assemblies 22a are arranged side-by-side at the lower part of the frame 21a, and the two tray lifting assemblies 23a are respectively arranged on the sides of the two tray conveying assemblies 22a. Adjacent tray conveying assemblies 22a and tray lifting assemblies 23a form a group, creating an infeed station and an outfeed station to respectively realize the functions of feeding and discharging materials. To transfer materials more accurately, both the frame 21a and the loading robot 25a are equipped with camera assemblies 27a for positioning the three-axis gantry slide 24a and the loading robot 25a.

[0072] During operation, the worker in the material silo 2a places the materials required for assembly onto the receiving tray 5a, places the receiving tray 5a on the material tray conveying assembly 22a at the feeding station, and transfers the receiving tray 5a to the corresponding material tray lifting assembly 23a via the material tray conveying assembly 22a. Then, the material tray 5a is lifted by the material tray lifting assembly 23a to bring it close to the three-axis gantry slide 24a. Afterwards, the loading robot 25a set on the three-axis gantry slide 24a takes out the materials from the receiving tray 5a and transfers them to the main display installation station 3a for subsequent installation.

[0073] To facilitate the transfer of the receiving tray 5a, the hopper 2a also includes a tray transfer assembly 26a, which is mounted on the frame 21a and located above the tray lifting assembly 23a. After the loading robot 25a removes the material from the receiving tray 5a, the empty receiving tray 5a is moved to the tray lifting assembly 23a at the discharge station via the tray transfer assembly 26a. The tray lifting assembly 23a then transfers the receiving tray 5a to the corresponding tray conveying assembly 22a, which then delivers the empty receiving tray 5a out.

[0074] The main display installation station 3a is located between the hopper 2a and the main display loading station 4a, for installing the display screen hinge and switch buttons, as well as transferring materials to the main display loading station 4a.

Specifically, the adsorption component 32a includes a lead screw slide 321a, a lifting cylinder 322a, and an adsorption nozzle 323a. The lead screw slide 321a is horizontally arranged on the material platform 31a for horizontal material transfer. The lifting cylinder 322a is installed on the sliding seat of the lead screw slide 321a, and the adsorption nozzle 323a is installed on the output shaft of the lifting cylinder 322a. The adsorption nozzle 323a is oriented towards the operating positions 311a for adsorbing and transferring materials.

[0076] In this embodiment, four operation positions 311a are sequentially arranged on the material platform 31a for feeding and temporary storage, main display shaft installation, switch button installation, and discharge and temporary storage, respectively. During operation, the loading robot 25a transfers the material to the operation position 311a for feeding and temporary storage, and then uses the adsorption component 32a to pick up and transfer the material to the operation position 311a for main display shaft installation to install the main display shaft. After that, the adsorption component 32a transfers the material to the operation position 311a for switch button installation to install the switch buttons. Finally, the adsorption component 32a transfers the material to the operation position 311a for discharge and temporary storage for storage, so that it can be used in the next assembly process.

[0077] Specifically, the number and setting order of operation positions 311a can be adjusted according to different assembly projects.

[0078] The main display loading station 4a is located on one side of the conveyor belt 1 to realize the functions of installing the speaker mesh and welding the antenna of the display screen, as well as transferring materials to the conveyor belt 1.

The first gantry robot 45a includes a rotary cylinder 451a and two suction components 452a. A cantilever 453a is provided on the rotation shaft of the rotary cylinder 451a. The two suction components 452a are respectively located at both ends of the cantilever 453a and are respectively located above the assembly fixture 46a and the conveyor belt 1.

[0081] In this embodiment, the transfer robot 43a, the antenna welding assembly 44a, and the first gantry robot 45a are respectively arranged around the periphery of the disk 42a to sequentially load / install the speaker mesh, weld the antenna, and unload the material; three assembly fixtures 46a are arranged around the edge of the disk 42a and are respectively set corresponding to the transfer robot 43a, the antenna welding assembly 44a, and the first gantry robot 45a.

[0082] During operation, the transfer robot 43a transfers the material from the temporary material storage position 311a in the main display installation station 3a to the corresponding assembly fixture 46a for speaker mesh installation. Then, the assembly fixture 46a is moved to the antenna welding assembly 44a by the rotating disc 42a for antenna welding. After that, the disc 42a moves the assembly fixture 46a to the first gantry robot 45a, where the suction unit 452a picks up the material in the assembly fixture 46a. The rotating cylinder 451a drives the cantilever 453a to rotate, thereby transferring the material to the conveyor belt 1, completing the main display online operation. The material is then transported to the LCD screen assembly station b via the conveyor belt 1 for subsequent assembly.
