[0025] As shown in Figures 1-2 The automatic feeding and discharging PCB tape sticking machine provided by the present application comprises a rack 100, a tape sticking assembly 300 and a material moving assembly 400, an in-out material assembly 200 comprises two jacking pieces 210, a first supporting plate 220 and a second supporting plate 230, the two jacking pieces 210 are installed on the rack 100, the top ends of the two jacking pieces 210 are jacking ends and are connected with the first supporting plate 220 and the second supporting plate 230 respectively; the tape sticking assembly 300 is installed on the rack 100 and has a tape sticking end; the material moving assembly 400 is installed on the rack 100 and has a material moving end, the material moving end is configured to grab the PCB on the first supporting plate 220 and move to a position abutting against the tape sticking end, and after the tape sticking, the PCB is moved to the second supporting plate 230.

[0026] In practice, the PCBs to be taped are stacked on the first tray 220 to complete the loading process. The transfer component 400 moves the topmost PCB on the first tray 220 to a position where it abuts against the tape application end. At the same time, the lifting component 210 moves the first tray 220 upward by a distance equal to the thickness of one PCB. The tape application end then applies tape to the PCB. The transfer component 400 moves the PCB abutting against the tape application end to the second tray 230. Simultaneously, another lifting component 210 moves the second tray 230 downward by a distance equal to the thickness of one PCB, thus completing the unloading process. By repeating the above steps, the automatic loading, unloading, and tape application of multiple PCBs can be completed, resulting in high production efficiency.

[0027] In this embodiment, the frame 100 is a load-bearing structure, which is a structure that can be conceived by those skilled in the art, and will not be elaborated or explained in detail here.

[0028] The feeding and discharging assembly 200 in this embodiment includes two lifting components 210, a first pallet 220 and a second pallet 230. The two lifting components 210 are mounted on the frame 100, and the top ends of the two lifting components 210 are lifting ends and are respectively connected to the first pallet 220 and the second pallet 230.

[0029] Whenever a PCB is picked up from the first tray 220 or placed onto the second tray 230, one of the lifting components 210 moves the first tray 220 upward by a distance equal to the thickness of a PCB. At the same time, the other lifting component 210 moves the second tray 230 downward by a distance equal to the thickness of a PCB, so as to facilitate the picking and placing of the PCB by the transfer assembly 400.
