[0067] Step S1, fixing the computer frame: placing the computer frame on the frame fixture 301 on the frame conveying mechanism 30 and fixing it;

[0068] Step S2, automatic assembly of the bracket: the bracket loading mechanism 7 puts the bracket on, and then the parts are assembled on the bracket by the parts assembly mechanism 8, and then the bracket unloading mechanism 9 places the assembled bracket on the computer frame on the frame fixture 301;

[0069] Step S3, computer screen transfer: while performing steps S1 to S2, the placement jig 11 with the screen is placed on the placement mechanism 1, and then the screen is grabbed and placed on the assembly jig 32 by the transfer mechanism 2, and then the assembly jig 32 with the screen is moved to the vicinity of the assembly robot 4 by the mobile platform 31;

[0070] Step S4, accessory assembly: The feeding mechanism 5 feeds the accessory, and then the assembly robot 4 grabs the accessory from the feeding mechanism 5. After the accessory is grabbed, it moves to the visual inspection device 33 for photography inspection, and then moves to the dispensing device 36 for dispensing glue on the accessory. After the dispensing is completed, the assembly robot 4 transfers the accessory to the assembly jig 32 and assembles the accessory on one side of the screen. After the assembly is completed, the assembly clamping device 35 presses and fixes the accessory.

[0071] Step S5, screen assembly: During steps S3 and S4, the front cover is placed on the placement jig 11. After step S4 is completed, the mobile platform 31 moves the assembly jig 32 toward the placement mechanism 1. The transfer mechanism 2 grabs the screen and places it on the front cover. The screen and the front cover are then manually secured with screws.

[0072] Step S6, assembling the computer frame. After completing steps S1 to S5, the frame is transferred toward the placement mechanism 1 through the frame conveying mechanism 30, and then the computer frame is manually grabbed from the frame fixture 301 and assembled to the front cover assembled in step S5 to fix the screen.

[0073] In this embodiment, the automatic assembly method of the computer screen frame and its supporting equipment significantly improve production efficiency and assembly accuracy. Through the automated process design, the automatic loading of the bracket, assembly and unloading of parts, and the precise transfer and positioning of the screen, the manual operation links are greatly reduced, the labor intensity is reduced, and the assembly quality problems caused by human errors are avoided. In the accessory assembly stage, the introduction of the visual inspection device 33 and the automatic dispensing ensure the precise assembly and reliable connection of the accessories, further improving the overall quality of the product. In addition, the parallel operation mode effectively utilizes the production time and shortens the assembly cycle while the outer frame is fixed and the bracket is assembled. Finally, the combination of the manual intervention of the screw locking and the front cover assembly steps retains the necessary flexibility to adapt to complex assembly requirements, and gives full play to the advantages of the automated equipment, achieving a balance between efficiency and accuracy. The present invention not only improves production efficiency, but also significantly enhances the assembly quality and market competitiveness of the product. Another important technical effect of the automatic assembly method of the computer screen frame is its high customizability and scalability. Through modular design and the flexible configuration of key components such as the parts assembly mechanism 8, transfer mechanism 2, and assembly robot 4, this solution can adapt to the assembly needs of computer screen frames of different specifications and models. When product lines need to be adjusted or upgraded, simply replacing or adjusting the corresponding modules can quickly reconfigure the production line, reducing renovation costs and time.
