[0010] Furthermore, a buffer pad is bonded to the top inner wall of the robot arm clamping frame.
[0011] Furthermore, a non-slip pad is bonded to one side of the clamping plate.
[0012] The beneficial effects of the utility model are:
[0013] 1. The setting of individually controlling the clamping plate by multiple electric push rods can be suitable for clamping goods with irregular surfaces, so as to clamp the goods stably.
[0014] 2. The turntable is driven by the first motor to rotate, thereby driving the robotic arm mechanism to rotate, and then adjusting the robotic arm mechanism to the direction of cargo stacking.
