Currently, the cutting and stacking of gear shaft components in the industry mainly relies on manual handling. This involves high labor intensity for operators, and the process is prone to quality risks such as bumps and damage during transportation. Furthermore, there is a possibility of errors or omissions in human operation. Summary of the Invention
[0003] To address the problems existing in the prior art, the present invention provides an automatic gear shaft unloading and stacking system and method, which solves the quality risks such as bumps and damage that are prone to occur during the transfer process, as well as the problems of human error and omissions.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] An automatic material unloading and stacking system for gear shafts includes a parts frame destacking and stacking station, a gripping robot station, a gear shaft material receiving and gripping station, a parts frame temporary storage station, and a control system.
[0006] The parts frame destacking and stacking station is used for destacking and stacking parts frames; the parts frame temporary storage station is used for placing empty parts frames; and the gear shaft material handling station is used for handling gear shafts.
[0007] The gripping robot station is equipped with a 3D camera, a gear shaft gripper, a gear shaft conveyor track, and a part frame gripper.
[0008] The gear shaft conveyor track is used to transport gear shafts, the gear shaft grippers are used to grip the gear shafts transported to the gear shaft material gripping station, and the parts frame grippers are used to grip the parts frame.
[0009] The 3D camera is used to take pictures of the part frame to confirm the position of the gear shaft chuck stacking the gear shaft in the part frame;
[0010] The control system controls the 3D camera, gear shaft chuck, gear shaft conveyor track, and part frame chuck.
[0011] Preferably, the part frame is provided with part frame positioning corner blocks for precise positioning of the part frame.

Detailed Implementation
[0030] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.
[0031] The present invention provides an automatic gear shaft unloading and stacking system, comprising a parts frame destacking and stacking station 9, a gripping robot station, a gear shaft receiving and gripping station 10, a parts frame temporary storage station 11, and a control system.
[0032] Parts frame destacking and stacking station 9 is used for destacking and stacking parts frame 3; parts frame temporary storage station 11 is used for placing empty parts frames; gear shaft material grabbing station 10 is used for grabbing gear shafts.
[0033] The gripping robot station is equipped with a 3D camera 5, a gear shaft gripper 6, a gear shaft conveyor track 7, and a part frame gripper 8.
[0034] The gear shaft conveyor track 7 is used to transport gear shafts, the gear shaft chuck 6 is used to grip the gear shafts transported to the gear shaft material gripping station 10, and the parts frame chuck 8 is used to grip the parts frame 3.
[0035] The 3D camera 5 is used to take pictures of the part frame 3 to confirm the position of the gear shaft chuck 6 stacking the gear shaft in the part frame 3.
[0036] The control system controls the 3D camera 5, the gear shaft chuck 6, the gear shaft conveyor track 7, and the part frame chuck 8.
[0037] The 3D camera 5 automatically identifies the position and status of the part frame 3 and the gear shaft. The part frame jaws 8 disassemble the three-layer part frame. The gear shaft jaws 6 grab the gear shaft, identify it through the 3D camera 5, and place it in the corresponding position in the part frame 3. The part frame jaws 8 stack the part frame 3 again. The gear shaft jaws 6 repeat the previous action to grab the gear shaft and place it in the corresponding position in the part frame 3.
[0038] like Figure 1 As shown, in the temporary storage station 11 for parts, after being destacking, parts 3 are placed in the temporary storage station 11 for parts. The parts 3 is precisely positioned by the positioning corner block 2. The magnetic sensor 1 under the parts 3 placement table 4 can accurately sense the parts 3 on the parts 3 placement table 4, which is convenient for the robot to grasp and identify in the future.
[0039] like Figure 2 As shown, in the robot gripping assembly, the gear shaft is conveyed along the gear shaft conveyor track 7 to the gear shaft material gripping station 10. After being identified by the 3D camera 5, it is gripped by the gear shaft claw 6. The head of the part frame claw 8 can be bent at 90° to realize the gripping and release of the part frame 3.
[0040] like Figure 3 As shown, empty parts frames (3 stacks in total) are delivered to the parts frame destacking and stacking station 9. The 3D camera 5 carried by the gripping robot takes 3D pictures of the incoming empty parts frames and transmits the 3D data of the identified empty parts frame stacks to the gear shaft chuck 6.
[0041] After the grabbing robot obtains the three-dimensional coordinate data of the empty part frame stack, it unpacks the empty part frame stack to the part frame temporary storage station 11. At this time, there is one empty part frame left in the part frame unpacking and stacking station 9. The gear shaft chuck 6 grabs the gear shaft from the gear shaft material grabbing station 10, reads the gear shaft placement position identified by the three-dimensional camera 5, and puts the gear shaft into the remaining empty part frame.
[0042] After the empty parts frame is filled, the parts frame claw 8 grabs the empty parts frame temporarily stored at the parts frame temporary storage station 11 and stacks it to the parts frame destacking and stacking station 9. The previous step is repeated until all three parts frames 3 are filled. Then, the three stacks of filled parts frames are conveyed to the next station along the track.
[0043] The present invention provides an automatic unloading and stacking method for gear shafts, comprising the following processes:
[0044] After the parts frame 3 is destacking, the empty parts frame is placed in the parts frame temporary storage station 11;
[0045] The gear shaft is conveyed along the gear shaft conveyor track 7 to the gear shaft unloading unit, and after being identified by the three-dimensional camera 5, it is gripped by the gear shaft chuck 6.
[0046] Empty parts frames are brought to the parts frame destacking and stacking station 9. The 3D camera 5 takes a 3D picture of the incoming empty parts frames and transmits the identified 3D data of the empty parts frame stack to the parts frame claw 8.
[0047] After the part frame chuck 8 obtains the three-dimensional coordinate data of the empty part frame stack, it unpacks the empty part frame stack to the part frame temporary storage station 11. The gear shaft chuck 6 picks up the gear shaft from the gear shaft material picking station 10, reads the gear shaft placement position identified by the three-dimensional camera 5, and puts the gear shaft into the empty part frame.
[0048] Once the empty parts frames are full, they are transferred to the next workstation.
[0049] The part frame gripper 8 grabs the empty part frames temporarily stored at the part frame temporary storage station 11 and stacks them to the part frame destacking and stacking station 9 to continue stacking.
