Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and particularly to an automatic conveying device for steel plate welding. Background Art

[0002] In the modern industrial system, the collaborative operation efficiency of material transportation and processing plays a decisive role in production benefits, especially in the manufacturing fields related to steel plate welding. With the booming development of industries such as construction, machinery manufacturing, automobiles, ships, and nuclear power equipment, the demand for steel plate welding processing not only continues to climb in quantity, but also sets higher standards in terms of quality and efficiency.

[0003] Traditional steel plate welding operations have many drawbacks in the material transportation link. Manually handling steel plates for loading and unloading not only has extremely high labor intensity, but also extremely low efficiency. Due to the instability of manual operations, steel plates are prone to deviation during handling and positioning, which will not only affect the welding quality, resulting in problems such as uneven welds and insufficient strength, but may also cause welding rework due to inaccurate positioning, further reducing production efficiency.

[0004] Although semi-automatic welding equipment has achieved partial automation, it still relies on a large amount of manual intervention in material transportation. Workers need to frequently manually place and remove steel plates, which makes the equipment idle during loading and unloading and cannot achieve continuous operation, greatly limiting the improvement of the overall welding efficiency. Moreover, frequent manual contact with the equipment and steel plates poses certain safety risks, such as scalding and bruising, increasing the enterprise's safety management costs.

[0005] In the field of automated welding, although some existing welding equipment has achieved automation of the welding process, there are obvious defects in the design of the material transportation link. Most equipment is only equipped with a single loading mechanism. After a steel plate is welded, it is necessary to wait for an operator to place the next steel plate in place. During this period, the welding equipment is idle, resulting in waste of time and resources and making it difficult to meet the requirements of large-scale and high-efficiency production.

[0006] In addition, the existing equipment also has prominent problems in the unloading link after welding. It often requires manual assistance to carry the welded steel plates, which not only increases the labor cost, but also easily affects the continuous operation of the welding equipment due to untimely manual handling, resulting in the stagnation of the production line. At the same time, there are certain safety risks during manual handling, which may cause harm to the operators. Summary of the Invention

When the ball screw two 6102 on the second lifting member 612 moves, its moving direction is opposite to that of the ball screw two 6102 on the first lifting member 610. That is, when the ball screw two 6102 on the second lifting member 612 is arranged, its spiral direction can be opposite to that of the ball screw two 6102 on the first lifting member 610, so as to realize that when the ball screw two 6102 on the second lifting member 612 moves up and down, it moves in the opposite direction to the ball screw two 6102 on the first lifting member 610. A triangular stable support for the rotating plate 42 is formed between the two first lifting members 610 and the second lifting member 612.

[0037] When the present invention is in use, the steel plate to be welded is placed on one of the tooling tables 4. The positioning cylinder 43 is used to push the steel plates to be aligned and position the steel plates. The positioning fixture 44 is started to further clamp and fix the steel plates, completing the welding positioning of the steel plates. The driving device 51 is started. The driving device 51 drives the ball screw one 32 connected to it through the first transmission assembly 52 to rotate. The rotating ball screw one 32 drives another ball screw one 32 to rotate together through the second transmission assembly 53, so that the two ball screws one 32 rotate synchronously. The ball nut one 321 on the ball screw one 32 can perform linear movement under the rotation of the screw, and drives the moving plate one 41 to slide on the first slide rail assembly 31 through the connecting block 322, so as to move the tooling table 4 on which the steel plates are placed towards the welding mechanism 2. After the steel plate to be welded moves to the welding position, the welding mechanism 2 starts to work. The first linear module 21 and the second linear module 22 move in coordination to drive the welder 23 to move in the two-dimensional plane to weld the steel plates. During this process, the steel plates to be welded are also placed on the other feeding member 3 in advance and positioned; After the steel plate on the first feeding part 3 is welded, the driving device 51 is started. When the ball screw 32 on the feeding part 3 rotates, the moving block on the ball screw 32 drives the corresponding moving plate to move outwards. Since the rotation directions of the ball screws 32 on the two feeding parts 3 are opposite, the other feeding part 3 moves the steel plate thereon to the lower part of the welding mechanism 2 through the feeding part 3 for welding, realizing staggered continuous feeding and welding. After the steel plate is welded, it is no longer necessary to position it. The positioning cylinder 43 and the positioning fixture 44 for fixing the steel plate are unlocked to avoid fixing the steel plate again, so that the steel plate can be smoothly discharged; During the return process of the welded feeding part 3, the second moving plate 67 moves with the feeding part 3. When the second moving plate 67 moves to a certain position, the first ratchet gear 682 meshes with the rack 65 on the first positioning plate 63. The rotation of the first ratchet gear 682 drives the input shaft of the first transmission 681 to rotate. After being speeded up by the first transmission 681, it drives the sleeve 6101 of one of the first lifting parts 610 to rotate through the third transmission component 683. The sleeve 6101 drives the ball screw 6102 to rotate. The second ball nut on the ball screw 6102 is fixed on the sleeve 6101, so that the ball screw 6102 moves upwards. When one sleeve 6101 rotates, the two connected sleeves 6101 can rotate synchronously through the fourth transmission component 611, and then the two ball screws 6102 move upwards synchronously. The upward moving ball screw 6102 moves the control block 6104 upwards through the top plate 6103. The control block 6104 pushes the hinge block 6106 through the pin rod 6107, and then pushes the rotating plate 42 to rotate and tilt, so that the welded steel plate on the rotating plate 42 can slide off. When the sleeve 6101 on the first lifting part 610 rotates, it can drive the sleeve 6101 on the second lifting part 612 to rotate synchronously through the fifth transmission component 613. When the ball screw 6102 on the first lifting part 610 moves upwards, the ball screw 6102 on the second lifting part 612 moves downwards, so that the rotating plate 42 can rotate and tilt, so as to fall into the lower collecting box or the conveyor belt, thereby automatically discharging the welded steel plate; After the ratchet gear 682 moves away from the positioning plate 63, the moving plate 67 continues to move. The ratchet gear 692 meshes with the rack 65 on the positioning plate 64. The rotation of the ratchet gear 692 drives the rotation of the input shaft of the transmission 691. After being speed-changed by the transmission 691, it drives the connected sleeve 6101 to rotate through the transmission gear set 693. The transmission member 69 drives the connected sleeve 6101 to rotate in the opposite direction relative to the transmission member 68 during rotation, so that the ball screw 6102 on the lifting member 610 can move downward. The ball screws 6102 on the two lifting members 610 move downward, and the ball screw 6102 on the lifting member 612 moves upward, thereby driving the rotating plate 42 to rotate back and reset, thus completing the automatic reset of the rotating plate 42 after the steel plate is cut.
