[0006] The beneficial effect of the utility model lies in that the first conveyor is used to convey the pallet filled with workpieces, and the second conveyor rises through the lifting mechanism so that the second conveyor is level with the conveying surface of the first conveyor, and the pallet filled with workpieces can enter the second conveyor, and then the workpieces on the pallet are transferred to the automatic cartoning machine for packaging process through the manipulator. After the loading and transfer of the workpieces on the pallet are completed, the second conveyor descends to the middle of the conveyor frame through the lifting mechanism, so that the conveying surface of the second conveyor is level with the pallet slide, and the second conveyor conveys the pallet into the pallet slide. Since the pallet slide is set at an angle, the pallet slides down under the action of its own weight, so that the workers can collect it. At the same time, the second conveyor continues to rise to the first conveyor through the lifting mechanism, and works in a cycle. There is no need for workers to frequently take away empty pallets separately, nor do they need workers to place pallets with workpieces at the position specified by the manipulator, thereby improving work efficiency, and the automatic transportation of the equipment is more convenient and flexible.

[0007] Furthermore, a first baffle is provided on the side of the second conveyor close to the robot frame, a second baffle is provided on the side of the second conveyor close to the automatic cartoning machine, and a centering mechanism is provided on the side of the second conveyor away from the robot frame, and the centering mechanism is installed on the lifting mechanism.

[0008] After adopting the above-mentioned further structure, the pallet can be easily pushed to the first baffle through the centering mechanism to complete the centering action, so as to facilitate the operation of the robot, and the second baffle can limit the position of the pallet when it is input into the second conveyor.

[0009] Furthermore, the lifting mechanism includes a support plate installed in the middle of the conveying frame, a lifting cylinder is installed at the lower end of the support plate, the cylinder shaft of the lifting cylinder passes through the support plate, and the cylinder shaft is connected to a conveying seat, the conveying seat is located above the support plate, the second conveyor is installed on the conveying seat, and the centering mechanism is installed on the side of the conveying seat.

[0010] After adopting the above-mentioned further structure, the conveying seat is driven by the lifting cylinder to switch between the first conveyor and the pallet slide, thereby driving the second conveyor to switch and connect the first conveyor and the pallet slide, so as to facilitate the replacement of pallets, make the equipment more flexible, reduce the work of operators, and improve efficiency.

[0011] Furthermore, a shaft sleeve is installed on the support plate, a guide rod is inserted into the shaft sleeve, and the upper end of the guide rod is fixedly connected to the lower end of the conveying seat.

[0012] After adopting the above-mentioned further structure, under the action of the guide rod, the conveying seat can be more stable during the lifting process.

[0013] Furthermore, the centering mechanism includes a connecting seat installed on the side of the conveying seat, a pushing cylinder is provided on one side of the connecting seat, a cylinder shaft of the pushing cylinder is connected to a centering plate, and the centering plate corresponds to the first baffle.

[0014] After adopting the above further structure, the centering plate can be driven to move by pushing the cylinder, so that the tray can be pushed to the first baffle plate to make the tray reach the specified position.

[0015] Furthermore, a tray sliding cavity is provided in the middle of the conveying frame, the tray slide is installed in the tray sliding cavity, a slide is provided in the tray slide, and a plurality of rubber rollers are provided in the slide.
