[0026] This utility model proposes an automatic PCB board unloading machine.

[0027] like Figure 1As shown in one embodiment of this utility model, an automatic PCB board unloading machine includes a frame 1. One end of the frame 1 is provided with a first transport track 2, and the other end of the frame 1 is provided with a TRAY tray loading and unloading mechanism 9. A second transport track 3 and a third transport track 4 are respectively provided on both sides of the first transport track 2 in the transport direction. A transfer mechanism 5 is provided above the third transport track 4, and the travel of the transfer mechanism 5 extends to the second transport track 3. The frame 1 is provided with a pouring port 7 at one end of the third transport track 4, and a pouring mechanism 6 is provided at the end of the third transport track 4 near the pouring port 7.

A barcode scanning component is fixedly provided at the output end of the transport mechanism 8.

[0028] In this embodiment, a pallet containing PCB boards is transported to the end via the first transport track 2. The handling mechanism 8 scans the PCB boards using its barcode scanning component and moves them onto the corresponding trays in the tray loading / unloading mechanism 9. After the PCB boards in the pallet have been transferred by the handling mechanism 8, the first transport track 2 transports the pallet back below the transfer mechanism 5. Then, the transfer mechanism 5 transfers the pallet to the third transport track 4, which in turn transports it to the unloading mechanism 6. The unloading mechanism 6 pours the waste material from the pallet into the unloading port 7. After the waste material is poured out, the transfer mechanism 5 transfers the empty pallet to the second transport track 3, which then moves the empty pallet away. This achieves automatic scanning and unloading of PCB boards and automatic emptying of waste material, thus improving production efficiency.

[0029] Specifically, the first transport track 2, the second transport track 3, and the third transport track 4 are arranged side by side.

Correspondingly, the conveying mechanism 8 simultaneously conveys the PCB boards in the two pallets on the first conveying track 2. After the conveying is completed, the two pallets are transported back to the bottom of the transfer mechanism 5 via the first conveying track 2, so that the transfer mechanism 5 can simultaneously grab and unload them. In addition, a baffle 41 is provided between the two unloading ports 7. The baffle 41 is located above the third conveying track 4, and a baffle 41 is also provided at the end of the third conveying track 4, so that the position of the two pallets conveyed by the transfer mechanism 5 can be adjusted and limited at the same time.

Then, the drive motors 63 drive the pallet to rotate and pour the waste material into the unloading port 7.

[0036] The vertical plate 61 is located near the discharge port 7. A proximity switch is installed at the end of the third transport track 4 near the discharge port 7.

The cylinder gripper 64 is driven by the fourth vertical drive assembly to move downward to clamp the tray. The cylinder gripper 64 is then raised and moved above the discharge port 7. The drive motor 63 rotates to pour the waste material in the tray into the discharge port 7. The second horizontal drive assembly is similar in structure to the first horizontal drive assembly 52, and the fourth vertical drive assembly is similar in structure to the first vertical drive assembly 53.

[0038] Optionally, the unloading mechanism 6 can also be a four-axis robot, which directly picks up the pallet and unloads the material.

[0039] Preferably, such as Figure 3 As shown, the conveying mechanism 8 includes a fixed base 81, a first rotating arm 82, a second rotating arm 83, and a third vertical drive assembly 84.

The fifth and sixth transport tracks 92 and 93 are used to place empty TRAY trays and move them below the transfer assembly, while the fourth transport track 91 is used by the handling mechanism 8 to load TRAY trays and transport full TRAY trays to the pre-loaded location. The empty trays on the fifth and sixth transport tracks 92 and 93 are transferred to the fourth transport track 91 by the transfer mechanism. Then, the PCB board is transported from the first transport track 2 to the tray on the fourth transport track 91 by the handling mechanism 8. When the tray is full of PCB board, the transfer component continues to place empty trays from the fifth and sixth transport tracks 92 and 93 on top of the trays full of PCB board. The above operation is repeated until the trays on the fourth transport track 91 are stacked to a preset height. Then, the fourth transport track 91 is driven to move the trays to a preset position for unloading.

[0045] Specifically, the working principle and usage process of this utility model are as follows: The pallet containing the PCB board is transported to the end via the first transport track 2. The handling mechanism 8 scans the PCB board with its barcode scanning component and moves the PCB board to the corresponding tray in the tray loading and unloading mechanism 9.

Then, the transfer mechanism 5 transfers the pallet to the third transport track 4. The third transport track 4 transports the pallet to the unloading mechanism 6. The unloading mechanism 6 pours the waste material in the pallet into the unloading port 7. After the waste material is unloaded, the transfer mechanism 5 transfers the empty pallet to the second transport track 3. The empty pallet is then moved away via the second transport track 3, thereby realizing automatic scanning and unloading of the PCB board and automatic unloading of the waste material, improving production efficiency.
