[0058] The working principle of the steering wheel airbag cover forming equipment provided by the present invention is as follows:

[0059] The mobile gripper 1001 and the injection molding machine 6 are both existing technologies. The mobile gripper 1001 generally adopts a three-jaw second pneumatic gripper 114.

[0060] During loading, the product is manually placed on the first conveyor belt 102 with the material in the tray 12, and the first conveyor belt 102 transports the material in the tray 12 to the loading plate 1014. The first rotating motor 1013 drives the lifting screw 1011 to rotate and drive the loading plate 1014 to move upward. The loading plate 1014 carries the material tray 12 through the material transportation hole 1031 and rises above the workbench 103. The loading plate 1014 transports the material tray 12 upward. When it moves to the rotating buckle 1061, the rotating buckle 1061 flips the feeding tray 12 upward to pass through. The arc surface on the bottom of the rotating buckle 1061 makes the rotating buckle 1061 flip more smoothly. After the sensor senses the tray 12 rising to the clamping cylinder 1052, the two clamping cylinders 1052 drive the clamping hands to move toward the tray 12. The stable clamping hands 1053 pass through the clamping slot to clamp the tray 12, and the loading plate 1014 transports the remaining trays 12 to move downward;

[0061] During transfer, the horizontal screw rod 1008 moves along the length direction of the vertical guide rail 1002, and the horizontal rotating seat 1005 moves along the length direction of the horizontal screw rod 1008 to adjust the position of the mobile clamping hand 1001 on the horizontal plane. When the mobile clamping hand 1001 moves to above the material to be clamped, the clamping hand cylinder 1015 drives the mobile clamping hand 1001 to move down to clamp the material. After the mobile clamping hand 1001 completes the clamping, the clamping hand cylinder 1015 drives the mobile clamping hand 1001 to move up. An identification camera is set above the mobile clamping hand 1001 or the material tray 12 to identify whether the front and back of the material are No, when the placement surface of the material on the tray 12 is correct, the mobile gripper 1001 moves to the material placement table 104 to place the material. When the placement surface of the material on the tray 12 is incorrect, the mobile gripper 1001 moves to the adjustment mechanism 112 to move the material into the two clamps. After the clamps of the second pneumatic clamp 114 clamp the material, the second rotary motor 113 rotates 180° to turn the material over. After adjustment, the clamps of the second pneumatic clamp 114 release the material, and the mobile gripper 1001 clamps the material again and moves the material to the material placement table 104 to place the material.

[0062] During injection molding, the material-picking robot 4 controls the robot fixture 404 to move to the top of the material placement table 104, and the robot fixture 404 rotates until its magnetic suction portion 4043 is opposite to the material placement table 104. The material on the material placement table 104 is adsorbed into the first material slot 4045. Then, the material-picking robot 4 controls the robot fixture 404 to move to between the movable mold and the fixed mold of the injection mold 602. Then, the cylinder shaft of the ejector cylinder 4044 pushes the guide block 4047 out. , the ejector pin 4048 on the guide block 4047 penetrates the first material slot 4045 of the magnetic attraction portion 4043, pushing the material into the second material slot 6022, and the injection molding press 601 performs injection molding into the injection slot 6021 of the injection mold 602. After the injection molding is completed, the material-retrieving robot 4 controls the gripping platform 4051 of the robot clamp 404 to rotate to the front of the second material slot 6022, and the first pneumatic gripper 4050 grips the material frame to remove the material;

[0063] When discharging, the material-picking robot 4 controls the gripping gripper 4049 of the robot clamp 404 to move to the side of the discharging seat 5 of the executing robot 3, and the executing robot 3 controls the discharging seat 5 to rotate to the position of the camera 502 corresponding to the gripping gripper 4049. The camera 502 takes pictures of the material clamped by the gripping gripper 4049 to read the position of the material. The executing robot 3 controls the discharging seat 5 to move and rotate to the position corresponding to the test guide pin 501 and the material. The test guide pin 501 performs a conductive test on the material. After the test is successful, the gripping gripper 4049 places the material on the platform 11, and the executing robot 3 controls the discharging seat 5 to move and rotate the air nozzle to the front of the label peeling machine 8. The active wheel of the pulley transmission group 807 is driven by a motor, thereby driving the active reel 8 04 rotates, causing the label to move down through the label platform 803. When the label reaches the bottom of the label platform 803, the bottom of the label begins to separate from the labeling paper behind the label, and the air nozzle moves to the front of the label platform 803 and moves down synchronously with the label. After the air nozzle sucks the label, it moves to the upper part of the material and presses down to stick the label on the material. Then the execution robot 3 controls the discharge seat 5 to rotate to the position where the pin 504 corresponds to the material. The cylinder drives the pin 504 to perform a forward poking action to mark the material, and then transmits the signal back to the execution robot 3. Finally, the execution robot 3 controls the discharge seat 5 to rotate to the position where the pneumatic discharge gripper 505 corresponds to the material, and places the material on the second conveyor belt 2. The second conveyor belt 2 transports the material to the manual material placement table 9, and the material is manually sorted and packed.

[0064] When the material on the tray 12 is taken out, the clamping assembly 105 is released, and the tray 12 falls due to its own gravity. Then, the rotating buckle 1061 rotates downward, and the clamping strip 1064 of the rotating buckle 1061 is clamped into the clamping groove of the fixed buckle 1062. The horizontal surface at the top of the rotating buckle 1061 supports the tray 12, and the hook 1307 is located below the empty tray 12. The transfer cylinder 1308 drives the hook 1307 to move the empty tray 12 to the storage plate 1304. The storage cylinder 1306 pushes the lifting plate 1305 to drive the storage plate 1304 to move upward, so that the empty tray 12 moves to the clamp assembly II 1302. Then the storage cylinder 1306 drives the storage plate 1304 to move downward, and the empty tray 12 is clamped on the clamp assembly II 1302 to realize the stacking of the empty trays 12.

However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
