Automatic steel plate automatic feeding and conveying device

Abstract

This application relates to the field of automated production equipment and material handling technology, and discloses an automated steel plate automatic feeding and conveying device, including a gantry robot, an adsorption and lifting mechanism, a pneumatic separating mechanism, an air supply mechanism, and a conveying and centering mechanism. After adsorbing the uppermost steel plate, the adsorption and lifting mechanism mechanically lifts the edges using a cylinder drive. Simultaneously, the pneumatic separating mechanism precisely aligns and lifts the gaps, blowing out high-pressure airflow. Through the combined mechanical and pneumatic action, the adhered steel plates are completely separated, eliminating the risk of stacking. When the separated individual steel plates are transferred above the conveying and centering mechanism, the air supply mechanism switches the air path to supply air to the hollow conveying plate, which sprays out through its surface holes to form a high-pressure air cushion. This air cushion steadily supports the falling steel plate, keeping it slightly suspended, providing a drop buffer while reducing static friction to an extremely low level, achieving resistance-free centering and positioning. This invention completely solves the technical problems of steel plates easily adhering due to oil film during loading, being susceptible to impact from gravity, and being easily scratched due to high friction during centering.

Description

Technical Field

[0001] This invention relates to the field of automated production equipment and material handling technology, specifically to an automated steel plate automatic feeding and conveying device. Background Technology

[0002] With the rapid development of modern industrial manufacturing technology, metal sheet processing occupies a pivotal position in automobile manufacturing, home appliances, aerospace and building materials. Before the deep processing of steel plates, such as stamping, bending or cutting, it is usually necessary to take out the stacked steel plates one by one and transport them smoothly to the designated processing station. In order to improve production efficiency, reduce the labor intensity of manual handling and ensure the safety of operators, most processing enterprises have introduced automated steel plate loading and conveying devices to replace traditional manual operations, realizing the automated transfer and continuous conveying of large batches of steel plates from the stack to the processing line.

[0003] Existing automated steel plate loading devices typically employ a conventional rigid vertical gripping structure during transfer operations. Their main mechanical structure and technical principles include a gantry frame or multi-axis robotic arm, and a rigid suction cup frame fixedly installed at the bottom of the execution end. During operation, the mechanical drive mechanism controls the suction cup frame to descend vertically above the steel plate stack, causing multiple vacuum suction cups arrayed at the bottom of the frame to simultaneously contact the surface of the top layer of steel plate. An external vacuum pump then generates negative pressure, using atmospheric pressure to adsorb and lock the entire steel plate. Finally, the mechanical mechanism directly and vertically pulls the suction cup frame upwards, separating the top layer of steel plate from the stack and transferring it horizontally onto a subsequent conventional roller or belt conveyor line for processing.

[0004] However, this traditional direct vertical adsorption lifting method has a significant and insurmountable technical flaw in practical applications: the stacked steel plates are prone to severe adhesion, easily leading to the simultaneous grabbing and feeding of "double" or even "multiple" plates. Since the steel plates are typically coated with anti-rust oil during manufacturing and storage, and their relatively smooth surfaces, their own weight causes almost all air to be expelled between the plates during stacking, creating extremely strong oil film surface tension and vacuum negative pressure adsorption force between the layers. When the existing rigid suction cup frame directly lifts the top layer of steel plate vertically upwards, this enormous interlayer adhesion force often tightly adsorbs and lifts the second or even third layer of steel plates below. This situation, where multiple steel plates are carried into subsequent processing equipment, not only results in direct waste of raw materials but also triggers serious "stacking" accidents, easily exceeding the processing equipment's limit load. This can cause devastating physical damage to expensive processing molds and stamping machines, forcing the entire production line to shut down for repairs and causing incalculable economic losses to the company. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automated steel plate automatic feeding and conveying device, which solves the problem that existing straight-up and straight-down feeding devices are prone to severe adhesion due to the tension of the anti-rust oil film between layers and the vacuum negative pressure when grabbing and stacking steel plates. This leads to multiple steel plates being fed together, causing stacking accidents, damaging processing molds, and causing production line shutdowns.

[0012] Preferably, a protruding plate is fixedly connected to the outer wall of the mounting rod, and a pressure spring is sleeved on the outer wall of the mounting rod, with the bottom end of the pressure spring fixedly connected to the upper surface of the protruding plate.

[0015] Preferably, the gas supply mechanism includes a gas storage tank, which is connected to an electromagnetic reversing valve via a first gas pipe.

[0018] This invention provides an automated steel plate automatic feeding and conveying device. It has the following beneficial effects:

[0019] 1. This invention effectively solves the industry problem of stacked steel plates easily sticking together due to oil film and negative pressure. By cleverly setting up an adsorption corner-lifting mechanism and a wind-powered separating mechanism, after the vacuum suction cup flexibly contacts and adsorbs the top layer of steel plate, the cylinder drives the flipping mounting plate to deflect upward, physically and mechanically lifting the two ends of the steel plate. At the same time, the motor and worm gear precisely adjust the pitch angle of the air knife, so that it is precisely aligned with the corner-lifting gap and blows in high-pressure airflow. This dual peeling mode of "mechanical corner lifting + precise wind-power assistance" eliminates the risk of multiple steel plates being fed together and greatly improves the reliability of layered feeding.

[0020] 2. This invention innovatively designs a high-pressure air cushion suspension buffer and zero-friction centering mechanism, which greatly extends the equipment life and protects the steel plate surface. Through the ingenious switching of the electromagnetic reversing valve, before the hollow conveyor plate receives the steel plate, its surface through holes will spray high-pressure air cushion upwards. This air cushion not only provides excellent flexible air cushioning, eliminating the rigid impact damage to the equipment caused by the steel plate falling due to gravity, but also lifts the steel plate to a micro-suspended state, so that when the push plate is centering and positioning, the static friction between the steel plate and the bottom surface is almost zero. This not only greatly reduces the resistance and energy consumption required for cylinder centering, but also effectively prevents the bottom surface of the steel plate from being scratched.

[0021] 3. The device of this invention has strong overall linkage, highly compact structure and high air source utilization. By using a unified air supply mechanism and reversing valve, it realizes the sharing and reuse of air source for the front-end air knife stripping and the rear-end air cushion lifting, saving manufacturing costs. The entire workflow, from precise transfer of the gantry and anti-adhesion stripping to resistance-free suspension centering and end processing, achieves seamless connection, significantly improving the overall production efficiency and product yield of the steel plate automated processing line, and has extremely high industrial promotion value.

The conveying centering mechanism 7 is slidably connected to the inner wall of the support frame 801.

[0034] As an important component of this invention, the specific structure of the adsorption corner-lifting mechanism 4 is as follows: it includes a first mounting post 401 fixedly connected to the lower surface of the fixed plate 3, a fixed mounting plate 404 fixedly connected to the lower surface of the first mounting post 401, a second mounting post 402 rotatably connected to both ends of the first mounting post 401, a flip mounting plate 403 fixedly connected to the lower surface of the second mounting post 402, and in order to realize the corner-lifting action, a first cylinder 405 rotatably connected to the upper surface of the fixed mounting plate 404, a U-shaped seat 406 rotatably connected to the output end of the first cylinder 405, a U-shaped seat 406 fixedly connected to the outer wall of the square plate 407, and the square plate 407 fixedly connected to the upper surface of the flip mounting plate 403.

[0035] In addition, a vacuum generator 408 is fixedly connected to the upper surface of the flip mounting plate 403 and the fixed mounting plate 404. A mounting rod 409 is fixedly connected to one end of the vacuum generator 408. The outer wall of the mounting rod 409 is slidably connected to the inner wall of the flip mounting plate 403 and the fixed mounting plate 404. A suction cup 413 for adsorbing the steel plate body 1 is fixedly connected to the bottom end of the mounting rod 409. In order to provide downward pressure buffer, a protruding plate 411 is fixedly connected to the outer wall of the mounting rod 409, and a pressure spring 412 is sleeved on the outer wall. The bottom end of the pressure spring 412 is fixedly connected to the upper surface of the protruding plate 411. The mounting rod 409 is limited and fixed above by a fixing nut 410 threadedly connected to it.

[0036] To assist in peeling off the adhered steel plates, the wind-powered separating mechanism 5 includes a first connecting rod 501 fixedly connected to the side wall of the fixed mounting plate 404, and a second connecting rod 502 fixedly connected to the lower surface of the fixed mounting plate 404. A frame 503 is fixedly connected to the bottom of the first connecting rod 501 and the second connecting rod 502. A rotating rod 505 is rotatably connected to the inner wall of the frame 503. An air knife 504 is fixedly connected to the outer wall of the rotating rod 505. To achieve precise adjustment of the blowing angle of the air knife 504, a protective shell 506 is fixedly installed on the outer wall of the frame 503. A motor 509 is installed inside the shell. A worm gear 508 is fixedly connected to the output end of the motor 509. The worm gear 508 is rotatably connected to the inner wall of the protective shell 506. A worm wheel 507 is fixedly connected to one end of the rotating rod 505. The teeth of the worm gear 508 and the worm wheel 507 mesh with each other to form a self-locking reduction transmission.

[0037] For the gas source switching part, the gas supply mechanism 6 includes a gas storage tank 601. The gas storage tank 601 is connected to an electromagnetic reversing valve 603 through a first air pipe 602. The electromagnetic reversing valve 603 is a three-position five-way electromagnetic reversing valve. The electromagnetic reversing valve 603 is fixedly installed on the outer wall of the support frame 801. The output ends on both sides of the electromagnetic reversing valve 603 are respectively fixedly connected to one end of a second air pipe 604 and a third air pipe 605. The other end of the second air pipe 604 is fixedly connected to the inner wall of the air knife 504. It should be noted that, in order to prevent spatial physical interference during long-distance movement, the second air pipe 604 and the third air pipe 605 are both flexible spiral air pipes, and they move synchronously with the gantry robot 2 and the conveyor plate 701 through an external drag chain structure, which effectively prevents the air pipes from getting tangled and being pulled and broken.

[0038] For the receiving and centering part, the conveying and centering mechanism 7 includes a conveying plate 701 slidably connected to the inner wall of the support frame 801 for receiving the steel plate body 1. The other end of the third air pipe 605 is fixedly connected to the bottom of the conveying plate 701. The conveying plate 701 has a hollow structure inside, and multiple through holes 702 are arrayed on its upper surface. The upper surface of the support frame 801 is fixedly connected to a first support 705 and a second support 707. The inner walls of the two are fixedly connected to a guide rod 706. The upper surface of the support frame 801 is also provided with a second cylinder 703. The output end of the second cylinder 703 is fixedly connected to a push plate 704. The inner wall of the push plate 704 is slidably connected to the outer wall of the guide rod 706. In addition, a linear drive module is fixedly installed on the inner side wall of the support frame 801. The linear drive module is fixedly connected to the conveying plate 701 and is used to drive the conveying plate 701 to slide back and forth along the inner wall of the support frame 801.

[0039] Working principle: When an automated steel plate automatic feeding and conveying device is needed, when the equipment is started, the gantry robot 2 is activated to control the fixed plate 3 to move horizontally to directly above the steel plate body 1 to be grabbed. Then, the gantry robot 2 drives the fixed plate 3 to move vertically downward, which drives the first mounting column 401, the second mounting column 402, the flipping mounting plate 403 and the fixed mounting plate 404 in the adsorption lifting mechanism 4 to move downward synchronously.

[0040] When the suction cup 413 contacts the surface of the uppermost steel plate body 1, the vacuum generator 408 is activated. The suction cup 413 is drawn into a vacuum state through the internal channel of the mounting rod 409, so that the suction cup 413 is firmly attached to the upper surface of the steel plate body 1. At the moment of contact, the mounting rod 409 is subjected to force and slides upward in the inner wall of the flip mounting plate 403 and the fixed mounting plate 404, and simultaneously compresses the pressure spring 412. The elastic force of the spring provides flexible buffering, effectively avoiding damage to the equipment or steel plate caused by rigid collision.

[0041] After adsorption stabilizes, the first cylinder 405 is activated to retract its output end, pulling the U-shaped seat 406 to rotate the square plate 407. This power causes the flip mounting plate 403 and the second mounting column 402 to deflect upward around the rotation center of the first mounting column 401, thereby driving the suction cups 413 set below the flip mounting plate 403 to rise synchronously, realizing the physical "flipping" action on the edges of both ends of the steel plate body 1, and initially breaking the adhesion effect between the steel plates caused by the oil film and vacuum negative pressure.

[0042] While the mechanical lifting action is maintained, the air tank 601 delivers high-pressure gas to the electromagnetic reversing valve 603. The electromagnetic reversing valve 603 is controlled to open the channel to the second air pipe 604, supplying air to the inside of the wind-powered splitting mechanism 5, causing the air knife 504 to blow out high-pressure airflow. At this time, the motor 509 is started simultaneously. The motor power drives the rotating rod 505 to rotate precisely through the reduction and self-locking transmission of the worm gear 508 and the worm wheel 507, thereby servo-adjusting the blowing pitch angle of the air knife 504. Through adjustment, the high-pressure airflow blown out by the air knife 504 is precisely aligned with the gap between the lifted upper steel plate body 1 and the lower steel plate for forced air blowing and peeling. The high-pressure air force and the mechanical lifting action are perfectly coordinated, eliminating the risk of multiple steel plate bodies 1 sticking together during feeding.

[0043] After successfully separating the single steel plate body 1, the gantry robot 2 is controlled to move it horizontally to directly above the conveyor plate 701 of the conveyor centering mechanism 7. During this period, the electromagnetic reversing valve 603 automatically switches the air path: the second air pipe 604 is closed to stop the air supply to the air knife 504, and the third air pipe 605 is opened to introduce high-pressure gas into the hollow conveyor plate 701. The high-pressure gas is evenly sprayed upward through the through holes 702 distributed in an array on the surface of the conveyor plate 701, forming a layer of "high-pressure air cushion" with lifting force above the conveyor plate 701.

[0044] Next, the vacuum generator 408 is de-vacuumed, causing the steel plate body 1 to detach. The falling steel plate body 1 is steadily supported by the "high-pressure air cushion" sprayed from below and is in a slightly suspended state. This not only plays an excellent air buffering role and effectively protects the conveyor plate 701 from the impact of gravity falling, but also converts the sliding friction between the steel plate body 1 and the conveyor plate 701 into air resistance, reducing the static friction to almost zero.

[0045] In the suspended state, the second cylinder 703 is activated simultaneously, driving the push plates 704 on both sides to move inward under the guidance and limit of the guide rod 706, so as to perform high-precision centering and positioning of the steel plate body 1 without resistance, which greatly reduces the energy consumption and wear required to drive the push plates 704.

[0046] Finally, the steel plate body 1, after being centered and positioned, lands smoothly on the conveyor plate 701 as the air cushion is released. Then, the conveyor plate 701 is driven by the linear drive module to slide along the inner wall of the support frame 801 and is accurately conveyed to the processing box 802 at the rear end for subsequent stamping and forming and other processing operations. This completes the entire automated, anti-sticking, and lossless feeding and conveying process.
