[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 and Figure 2As shown, the robot loading and unloading workstation for multiple silos of the present embodiment includes a frame 1, on which an articulated robot 2 and a silo lifting station 3 are arranged, the silo lifting station 3 includes multiple groups of silo mechanisms 301 and lifting mechanisms 302, the silo mechanisms 301 include several groups of fixed blocks 3011 and positioning columns 3012 arranged on the frame 1, the positioning columns 3012 enclose a storage space for placing materials, and the lifting mechanism 302 includes a tray 3021 movably arranged on the positioning columns 3012 and a driving assembly 3022 for driving the tray 3021 to reciprocate in a vertical direction. The robot loading and unloading workstation for multiple silos becomes an independent integrated workstation by arranging an articulated robot 2 and a silo lifting station 3 on a frame 1. It occupies a small space and can adapt to automated operations in a small area. The silo lifting station 3 includes multiple groups of silo mechanisms 301 operating side by side, realizing multiple groups of stacked feeding in a limited space and maximizing space utilization. Different silo mechanisms 301 can be used for the supply of raw materials and for the storage of finished or semi-finished materials. It has high flexibility and good compatibility, and can ensure a large material capacity. In conjunction with the articulated robot 2, it can adapt to the automated loading and unloading needs of various types of equipment. It has a wide range of applications and can effectively reduce the workload of staff and improve processing production efficiency.

[0021] Specifically, in this embodiment, the number of groups of the silo mechanism 301 and the lifting mechanism 302 in the silo lifting station 3 is set to four groups, and each group of the silo mechanism 301 includes three groups of fixed blocks 3011 and positioning columns 3012, and the three groups of positioning columns 3012 enclose a storage space for placing materials.

[0022] Preferably, the driving assembly 3022 includes a driving motor, a gear and a rack, the gear is connected to the output end of the driving motor, the rack is meshed with the gear, and the tray 3021 is connected to the end of the rack and is arranged to float. In this embodiment, the driving assembly 3022 adopts the form of gear rack transmission, which has the advantages of large power transmission, stable operation, and high reliability. In other embodiments, the driving assembly 3022 can also use a screw, a crank connecting rod mechanism, a cylinder telescopic mechanism and other components with reciprocating movement function, which is not limited to this embodiment.

[0024] Preferably, the frame 1 is provided with a material sensing switch 6 for detecting the arrival of materials.

[0025] In actual application, the lifting action of the rack drives the tray 3021 and the materials thereon to perform lifting and lowering movements. In the feeding state, the rack rises until the material sensing switch 6 detects that the material is in place. At this time, the articulated robot 2 can go to the corresponding silo mechanism 301 to pick up the material after receiving the material signal. After taking the material, the rack rises again until the material sensing switch 6 detects that the material is in place again, and the above steps are repeated to achieve continuous feeding; if the upper limit position sensing switch 4 detects the preset upper limit position signal on the rack, it means that the material of the current silo mechanism 301 has been emptied, and the silo mechanism 301 switches from the feeding state to the receiving state; in the receiving state, the rack descends until the material sensing switch 6 detects no material. At this time, the articulated robot 2 receives the material discharge signal and places the processed finished product into the corresponding silo mechanism 301. The material sensing switch 6 detects that the material is in place, triggering the rack to descend again until the material sensing switch 6 detects no material again, and the above steps are repeated to achieve continuous material collection; if the lower limit position sensing switch 5 detects the preset lower limit position signal on the rack, it means that the material of the current silo mechanism 301 is full. Preferably, a control button panel is also provided on the frame 1, and the staff can manually switch the feeding or receiving state of each group of silo mechanisms 301 through the control button panel.

[0026] Preferably, a plurality of sets of movable casters 7 are provided at the bottom of the frame 1. In this embodiment, four sets of movable casters 7 are installed at the bottom of the frame 1. The movable casters 7 are in the form of Foma wheels, which have the advantages of high mobility, strong bearing capacity, and good durability. The two states of fixed and mobile states can be switched, so that the robot loading and unloading workstation can be moved to different equipment for operation, giving full play to the flexibility of use.

[0027] Preferably, the articulated robot 2 includes an end effector 201 for grabbing materials. In this embodiment, the articulated robot 2 can select an appropriate end effector 201 to grab materials according to the characteristics of the materials to be processed, such as tubular, spherical, sheet, etc., and can adapt to the loading and unloading requirements of various equipment such as CNC lathes, machining centers, grinders, etc.
