Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and in particular to a material unloading device for a chassis production line. Background Technology

[0002] A circular disc structure with a frame is a type of mechanical part. Its main body is a circular disc with a raised annular frame around its outer perimeter, serving both support and connection functions. In the assembly line production process, in order not to affect the subsequent quality of the workpiece, a blanking device for the chassis production line has emerged to meet the needs of subsequent assembly and use.

[0003] Traditional chassis production line unloading equipment transports workpieces to designated positions via conveyor belts, where they are gripped by robotic arms or suction cups. The workpieces are then transferred to a palletizing area for stacking. While this equipment is simple in structure and low in cost, it suffers from insufficient positioning accuracy, low palletizing efficiency, inability to meet the demands of high-speed production, and other drawbacks. Existing chassis production line unloading equipment uses servo motors and a vision recognition structure to achieve high-precision positioning and rapid gripping. Multi-axis robotic arms complete the automatic palletizing operation. However, in actual use, these devices lack a limiting stacking mechanism, causing slight misalignment of the suction cups during gripping, affecting the accuracy of palletizing and transfer efficiency, and failing to meet the high-precision and high-efficiency production requirements of modern production lines.

[0026] In summary, the present invention has at least one of the following beneficial technical effects:

[0027] 1. This invention generates a magnetic field by energizing an electromagnetic coil on a fixed ring. Under the action of the magnetic field, the metal chassis is attracted to the center area of ​​the fixed ring. Since the two magnetic blocks have opposite magnetisms in the initial state, they attract each other. The pressure sensor at the rear senses the slight pressure change and sends a signal to the main control unit. The motor then drives the shaft to deflect the second magnetic block, changing the magnetic pole. The limit rod quickly rebounds under the action of magnetic force and telescopic folds, thereby accurately pushing the chassis to the designated position.

[0028] 2. This invention generates airflow by activating an air pump, which drives the rotating blades inside the vortex shroud to rotate, thereby causing the brush strips to rotate. This effectively removes dust from the chassis perimeter. The removed dust is carried by the airflow through the screw channel and suction pipe into the dust collection box for rapid collection. During operation, the rotating blades drive the rotating wheel to rotate smoothly via a connecting shaft, ensuring stable overall operation. The entire process integrates airflow attraction and brush strip assistance, achieving highly efficient cleaning of dust around the chassis.

[0029] 3. In this invention, when the transfer suction cup moves the chassis to the stacking area for release, a buffer structure is provided to prevent damage due to falling from a height. When the chassis falls, a silicone pad provides initial support. The four corners of the silicone pad are connected to the column through positioning ropes, which can effectively transmit the impact force. The column is equipped with a slider and a spring. The impact force drives the slider to compress the spring to absorb energy. Then the spring pushes the slider to return to its original position smoothly, thereby effectively improving the product yield. Attached Figure Description

Several bottom strips 13 are provided on the bottom surface of wooden support 12. Bottom strips 13 support and stabilize wooden support 12.

[0049] Working principle: First, after the transfer suction cup 11 picks up the chassis from the conveyor belt 10 and releases it onto the base platform 2, the electromagnetic coil 304 on the fixing ring 302 is energized. Therefore, a magnetic field is generated within one revolution of the fixing ring 302. When a deviation is detected as the chassis falls, because the chassis is made of metal with a high iron content, it is propelled to move from the boundary of the fixing ring 302 towards its center. At this point, the basic limiting of the chassis is completed. During this basic limiting process, the chassis, due to its displacement, touches a certain direction of the limit within the fixing ring 302. Position rod 305 causes limit rod 305 to move. Since the first magnetic block 306 and the second magnetic block 312 have opposite magnetism in the initial state, they attract each other. Pressure sensor 313 is fixedly connected to the rear side of the second magnetic block 312. When pressure sensor 313 detects a slight pressure change, it will send a signal to the main control unit. Then, motor 311 drives shaft 301 to make the second magnetic block 312 deflect at a flat angle. The magnetic poles of the second magnetic block 312 change, causing the limit rod 305 to quickly rebound under the drive of magnetic change and telescopic fold 315, thereby causing the chassis to move to the designated position.

[0050] Furthermore, when it is necessary to clean the area around the chassis, the suction pump 413 is activated. The suction pump 413 generates airflow, which causes the rotating blade 408 located inside the vortex cover 410 to rotate. In turn, the rotating blade 408 drives the brush strip 403 under the top plate 406 to rotate. As the brush strip 403 rotates, the dust around the chassis falls off and finally enters the dust collection box 404 through the suction pipe 414 via the screw channel 411 inside the vortex cover 410. During its operation, the rotating blade 408 drives the rotating wheel 407 to rotate through the connecting shaft 409, thereby ensuring the stable operation of the rotating blade 408. The entire process, through airflow suction and the auxiliary cleaning of the brush strip 403, enables the efficient cleaning of dust around the chassis.

[0051] Finally, when the transfer suction cup 11 moves the chassis to the stacking area, during the release process, due to the certain height, a certain buffer structure is needed to prevent the chassis from falling and being damaged. When the chassis falls, the silicone pad 509 on the base 2 supports its movement. The four corners of the silicone pad 509 are fixedly connected to the positioning rope 508. When the chassis touches the silicone pad 509, the positioning rope 508 transmits the impact force of the chassis falling to the column 510 on the frame 1. The column 510 is equipped with a sliding plate 505 and a spring 507. When the impact force is generated, the sliding plate 505 drives the spring 507 to move along the direction of gravity. When the impact force is gradually offset, it gradually returns to its original position, thus providing better protection for the chassis during the unloading process, avoiding collisions, and effectively improving the yield of the workpiece.
