[0008] The transport area includes a first lifting transport area, a second lifting transport area and a third lifting transport area which are arranged in parallel and used for the return flow of the pallets. The first lifting transport area is used to input or output the pallets, the second transport area is used to temporarily store the pallets, and the third transport area is used to send the pallets to the processing area.

[0009] In some specific embodiments, the clamping portion includes a slider slidably connected to the first slide rail and the second slide rail respectively, a first cylinder connected to the slider, and a clamping plate provided at a movable end of the cylinder.

[0010] In some specific embodiments, a groove is provided on the upper surface of the sliding block, and the cylinder is disposed in the groove.

[0011] In some specific embodiments, the clamp is L-shaped, including a first bent portion connected to the movable end of the cylinder and a second bent portion for supporting the tray.

[0012] In some specific embodiments, the upper surface of the tray is provided with a plurality of positioning grooves for accommodating bolts.

[0013] In some specific embodiments, limiting posts are provided at the four corners of the top of the tray, and limiting grooves matching the limiting posts are provided at the four corners of the bottom, so that the trays can be stacked after the limiting posts are inserted into the limiting grooves.

The second lifting and transporting area 3 rises or descends to a certain height, so that the positioning column 501 at the movable end of the lifting cylinder is inserted into the limiting groove 902 at the bottom of the pallet 9 to temporarily store the second batch of pallets 9.

[0042] S4. After the bolts are processed, the pallet 9 loaded with the processed bolts is returned to the third lifting and transporting area 2 by the robotic arm, and the clamping part 8 on the second slide rail 9 slides to the third lifting and transporting area 4, so that the cylinder 801 on the second slide rails 7 on both sides pushes the clamping plate 802 to clamp the bottom of the pallet 9, and slides along the second slide rail 7 to the first lifting and transporting area 2. The first lifting and transporting area 2 rises or falls to a certain height, so that the positioning column 501 at the movable end of the lifting cylinder is inserted into the limiting groove 902 at the bottom of the pallet 9. When the first batch of pallets 9 are returned to the first lifting and transporting area 2, the logistics cart will send out the first batch of pallets 9.
