The material frame transfer mechanism 3 includes two parallel YZ moving modules 301 and a lifting arm 302 fixedly connected to the moving table of the YZ moving module 301. Between the two YZ moving modules 301 on the lower frame, a roller line 6 is arranged, and the roller line 6 is used for feeding the PCB material frame 9. The flipping and picking mechanism 4 includes a first XY moving module 401, a rotating assembly 402 and an adsorption assembly 403. The lifting and picking mechanism 5 includes a second XY moving module 501, a seat plate 502 fixed on the moving table of the second XY moving module 501 and a Z moving module 506. On the moving table of the Z moving module 506, a clamping jaw cylinder 503 is arranged. On both sides of the seat plate 502, a misalignment cylinder 504 is arranged. On the sliding table of the misalignment cylinder 504, a vacuum adsorption plate 505 is fixedly connected.

[0020] Water pipes are arranged on both the upper and lower sides of the water tank 2. The water pipe on the upper side of the water tank 2 is used for water inlet, and the water pipe on the lower side of the water tank 2 is used for drainage. A water level sensor is arranged inside the water tank 2, and the water level sensor can monitor the water level in the water tank 2 to prevent overflow.

[0021] Above the material frame transfer mechanism 3 on the upper frame, a barcode scanner 7 and a CCD camera 8 are arranged. The barcode scanner 7 can scan the barcode on the PCB material frame 9 to read whether the information of the PCB product conforms to this production batch. The CCD camera 8 is used to detect the number of PCB boards in the PCB material frame 9.

[0022] The PCB material frame 9 includes a material frame body 901. At the bottom of the material frame body 901, a bottom plate 902 is arranged. Multiple V-shaped grooves are opened on the bottom plate 902, and the V-shaped grooves can limit the lower end of the PCB board material. Multiple cross bars 903 are arranged in parallel at the feeding port of the material frame body 901, and the cross bars 903 can limit the upper end of the PCB board.

[0024] The working principle of the present utility model is as follows: When in use, when the PCB material frame 9 filled with PCBs is fed from the roller line 6, then the YZ moving module 301 drives the lifting arm 302 to move to the groove at the F-shaped side bracket 904 of the PCB material frame 9 to lift and transfer it into the water tank 2. Then, water is injected into the water tank 2 for flushing. After the water washing is completed, the YZ moving module 301 drives the PCB material frame 9 to rise for draining. Then, the lifting and picking mechanism 5 grabs the PCB board and rises in sequence through the clamping jaw cylinder 503. After each PCB is clamped and lifted, the vacuum adsorption plate 505 is driven by the dislocation cylinder 504 to further adsorb the PCB and then loosen the clamp. Finally, the PCB on the vacuum adsorption plate 505 is transferred to the conveyor line 1 for feeding through the flipping and picking mechanism 5.

[0025] When in use, the present utility model can transfer the PCBs in the PCB material frame 9 to the conveyor line 1, or transfer the products on the conveyor line 1 to the PCB material frame 9.
