[0020] See Figures 1 to 5 As shown, it is a positioning bracket and PCBA board assembly equipment for notebook touch module, which includes: an assembly line transfer module 1, a tray loader 2 arranged beside the assembly line transfer module 1, a material picking robot 3 arranged between the tray loader 2 and the assembly line transfer module 1 and used to grab the PCBA board and transfer the positioning bracket A, a pressure holding mechanism 4 arranged beside the material picking robot 3, a lower visual inspection module 5 arranged below the movement stroke of the material picking robot 3 and used to detect product quality, and a defective product storage platform 6 arranged beside the lower visual inspection module 5, wherein the assembly line transfer module 1 is used for the transfer of the PCBA board, and the tray loader 2 is used for loading the positioning bracket A. The assembly line transfer module 1 is used to transfer the PCBA board, and the tray loader 2 is used to feed the positioning bracket A. The PCBA board is grabbed by the material picking robot 3 to the pressure holding mechanism 4 instead of manual labor, and then the positioning bracket A is grabbed from the tray loader 2 and placed on the PCBA board in the pressure holding mechanism 4. The pressure holding mechanism 4 fastens the positioning bracket A to the PCBA board, and finally the pressed finished product is taken out by the material picking robot 3. After inspection and judgment by the lower visual inspection module 5, the qualified product is placed back on the assembly line module 1 and transferred to the next workstation, while the unqualified product is directly placed on the defective product storage platform 6, thereby realizing the automatic organization of the PCBA board and the positioning bracket A, replacing manual operation, and greatly improving production efficiency.

[0021] The pallet loader 2 includes a pallet storage box 21, a lifting frame 23 disposed in the pallet storage box 21 and capable of placing at least two pallet containers 22, a plurality of pallets 24 vertically placed in the pallet container 22 and capable of being independently withdrawn, a pallet extraction module 25 disposed on one side of the pallet storage box 21 and used to pull out the pallet 24 for the material taking manipulator 3 to take out the material, and a Z-axis driving device 26 for driving the lifting frame 23 to move up and down so that pallets 24 of different heights can be taken out by the pallet extraction module 25.
