Description

Technical Field

[0001] The invention belongs to the technical field of thin plate transportation, and in particular relates to a metal thin plate transportation device. Background Art

[0002] Sheet metal is a thin metal material widely used in many industries such as automobiles, construction, electronics, and aerospace. Common sheet metal materials include carbon steel, stainless steel, aluminum, and copper, which are favored for their excellent physical and chemical properties. The production of sheet metal usually adopts processes such as cold rolling and hot rolling to ensure its surface quality and dimensional accuracy. Due to its lightweight and high strength, sheet metal can not only reduce product weight and improve energy efficiency, but also realize a variety of processing methods, such as welding and cutting, to meet complex design requirements. Therefore, sheet metal plays an important role in modern industry and is an indispensable basic material in the field of manufacturing and construction.

[0003] Metal sheets are usually processed and manufactured from different materials, which makes it difficult to transport the metal sheets due to the different sizes of the metal sheets during transportation. When the existing metal sheet transportation device is working, due to the different widths of different types of thin plates, the metal sheets of different widths are adsorbed at the same position during transportation, so that the metal sheets are easily deformed and unstable during transportation. In addition, when the metal sheets are transported and placed on their side, the existing metal sheet transportation device cannot be adjusted, resulting in the operator usually needing to manually operate the metal sheets when they are placed on their side, resulting in complicated operation and slow transportation during the transportation of the metal sheets, thereby greatly reducing the work efficiency of metal sheet transportation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a metal sheet conveying device.

[0005] The technical solution adopted to solve the above technical problems is: a metal sheet handling device, comprising a crossbeam, the top of which is fixedly connected to two supporting steels, and the tops of the two supporting steels are fixedly connected to hanging steels; A lifting ring is fixedly connected to the top of the hanging steel, an adjusting mechanism is installed at the front and rear ends of the crossbeam, an adsorption mechanism is installed at the top of the crossbeam, and a rotating mechanism is installed at one side of the adjusting mechanism.

[0006] Furthermore, the adjustment mechanism includes a support body fixedly connected to the top of the beam, a sliding groove is provided inside the support body, a first motor is fixedly connected to the top of the support body, a threaded rod is fixedly connected to the output end of the first motor, a connecting body is threadedly connected to the outer wall of the threaded rod, the front and rear ends of the connecting body are rotatably connected to two arc-shaped support rods, the front and rear ends of the beam are fixedly connected to a plurality of support seats, and two connecting rods are rotatably connected inside the plurality of support seats, a support block is rotatably connected between every two of the arc-shaped support rods, an inner groove is provided inside the plurality of support blocks, the threaded rod runs through the support body, the outer wall of the connecting body is slidably connected to the sliding groove, the connecting body is in the shape of four strips, the other ends of every two connecting rods are rotatably connected to the corresponding inner grooves, and every two connecting rods are distributed up and down.

[0007] By using the above technical scheme, when the metal sheet is transported, it is adjusted according to the width of the metal sheet, and the width of the adsorption on the surface of the metal sheet can be controlled by the adjustment mechanism, so as to ensure that the adsorption of thin plates with various widths can be controlled to the side of the metal sheet as much as possible when transporting, thereby reducing the swing of the thin plate and avoiding the deformation of the thin plate during transportation. In addition, the adjustment function enables the operator to make adjustments according to actual needs, thereby reducing the intensity of manual operation. At the same time, the quick adjustment of the distance between the suction cups can shorten the operation time, improve work efficiency, and make the transportation process more flexible and efficient. Specifically, when the metal sheet is transported, a lifting device is used to connect with the lifting ring on the top of the hanging steel of the device. According to the width of the thin plate, the first motor on the top of the support body is started to drive the threaded rod to rotate. At this time, the connecting body is at the top and can be The metal sheet with the largest width will be transported, and then the connector will move along with the rotation of the threaded rod. As the threaded rod rotates, the connector will move downward along the sliding groove inside the support body, and under the traction of the two connecting rods connected inside the support seat, multiple arc-shaped support rods will converge to the middle and make a certain circular motion. At this time, the distance can be gradually reduced from the maximum width. The operator can choose according to the metal sheets of different widths, so as to maximize the role of the transport device, until the connector slides to the bottom of the support body, at which time the arc-shaped support rod will move to the maximum limit, and the support blocks on both sides will converge in the center. At this time, the metal sheet with the smallest width can be transported. After the adsorption is completed, the lifting equipment is lifted to lift the transport device, thereby realizing the transport of metal sheets of different widths.

[0008] Furthermore, the adsorption mechanism includes a vacuum pump fixedly connected to the top of the beam, two first spring-type pipes are fixedly connected to the top of the vacuum pump, a plurality of pipe buckles are fixedly connected to the front and rear ends of the beam, a plurality of pipe buckles are fixedly connected to the inside of each of the straight pipes, a plurality of connecting pipes are fixedly connected to the top of the outer walls of the two straight pipes, wherein a plurality of connecting pipe input ends are fixedly connected to a second spring-type pipe, and the two first spring-type pipe input ends are respectively fixedly connected to the corresponding connecting pipes.

[0009] Through the above technical scheme, after selecting according to the width of the metal sheet, the adsorption mechanism can be used to adsorb the metal sheet, so that the metal sheet can be transported as the transport device moves. At the same time, when the adsorption mechanism is used to transport the metal sheet, the problem that metal sheets of different materials cannot be magnetized during transportation can be avoided. By using the adsorption mechanism, the contact area of ​​the suction cup with the thin plate is larger, which can reduce local pressure and thus reduce potential damage to the surface of the thin plate. Specifically, after the width distance placement control is completed, the vacuum pump on the top of the beam is started at this time. The second spring-type pipe connected to the two first spring-type pipes and multiple connecting pipes can pass the gas through the inside thereof, thereby realizing the suction required for transporting the metal sheet, thereby ensuring that the surface force of the metal sheet is evenly distributed during transportation.

[0010] Furthermore, the rotating mechanism includes a second motor fixedly connected to one side of two of the support blocks, the output ends of the two second motors are fixedly connected to a driving shaft, the other ends of the two driving shafts are fixedly connected to a placement body, the interior of the placement body is fixedly connected to an air intake pipe, the input end of the air intake pipe is fixedly connected to a suction cup, a plurality of the support blocks are rotatably connected to connecting shafts, a plurality of the second spring-type pipe input ends are respectively fixedly connected to the corresponding air intake pipes, the driving shaft passes through the interior of the support block, and a plurality of connecting shaft ends are respectively fixedly connected to the corresponding placement bodies.

[0011] Through the above technical scheme, when the adsorption mechanism is started, the rotating mechanism can be cooperated to adsorb the metal sheet, and the transportation of the metal sheet can be completed at this time. When some metal sheets are transported, the metal sheet can be kept standing on its side. By letting one side of the sheet stand up first, the operator can more conveniently adjust and position the sheet, thereby reducing the difficulty of operation. At the same time, when the metal sheet is standing on its side, the rotating mechanism and the adjusting mechanism can be cooperated, and can be selected according to metal sheets of different thicknesses to improve the applicability of the transportation device. At the same time, double-sided adsorption is used to ensure that the metal sheet is in a vertical state, and the operator can better control the sheet to avoid accidental slipping, thereby improving the safety of operation. Specifically, when the metal sheet needs to be transported in a plane, the surface of the metal sheet can be adsorbed by multiple suction cups, and the suction force is generated by connecting the air intake pipe through the input end of the second spring-type pipe, thereby realizing the stable transportation of the metal sheet. At the same time, when the metal sheet is standing on its side, the adjusting mechanism can be used to adjust it to drive the crossbeam Multiple suction cups at one end absorb the metal sheet, and the lifting equipment will pull the handling device upward, and then start the second motor on one side of the support block to drive the drive shaft to rotate. Since the multiple placement bodies and the connecting shaft are fixedly connected, the placement bodies and the connecting shaft will be driven to rotate, so that the suction cup can rotate. When the metal sheet remains vertical, the adjustment mechanism can be used to adjust according to the thickness of the metal sheet, and the distance can be reduced to an appropriate distance according to the thickness of the metal sheet. At the same time, relevant adjustments are made to ensure that the metal sheet has sufficient stability when being transported in a sideways state, and then start another second motor until the multiple suction cups at the other end of the beam absorb the other side of the metal sheet. At this time, the lifting equipment can lift the sheet and put it in an upright state. The contact area is relatively small, which can reduce friction and damage to the surface of the sheet. In addition, since the device will run in a circular arc when the adjustment mechanism is adjusted, the rotation mechanism can be used to ensure the adsorption angle, thereby completing the handling of the metal sheet.

[0012] The beneficial effects of the present invention are as follows: (1) The present invention, by designing an adjustment mechanism, an adsorption mechanism and a rotation mechanism, can adjust the metal sheet according to the width of the sheet during transportation. By adjusting the spacing of the suction cups, the edge of the sheet can be better fitted, the suction force can be increased, the risk of slipping or falling during transportation can be reduced, the safety can be improved, and the stability during transportation can be increased. In addition, the metal iron sheet can be transported sideways to effectively utilize the vertical space, especially in a narrow working environment, so that it can be transported more flexibly and the efficiency of space utilization can be improved. At the same time, the suction cup can be used to transport various materials, including non-magnetic metals such as aluminum, copper, and stainless steel. (2) The present invention, by designing an adjustment mechanism and an adsorption mechanism, can allow the metal When the thin plate is being transported, the distance between the suction cups on both sides can be adjusted, and the position of the suction cups can be adjusted according to the thin plates of different widths. During the transportation process, the appropriate suction cup spacing can evenly distribute the suction force, reduce the local pressure on the thin plate, and thus avoid deformation or damage to the thin plate; (3) The present invention designs a rotating mechanism, so that when the thin plate is transported sideways, the metal thin plates of different materials can stand on one side first, and the side where the thin plate stands is adsorbed first, which can ensure that its center of gravity is well controlled, reduce the risk of tipping or sliding, and thus improve the stability of the transportation process. In addition, it can be adjusted according to the metal thin plates of different thicknesses, and double-sided adsorption is performed. By adsorbing at both ends, the weight can be distributed more evenly, reducing the pressure on the middle part of the thin plate and reducing the possibility of deformation.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] like Figure 1-Figure 7 As shown, in this embodiment, Figure 1As shown, the metal sheet handling device of this embodiment includes a crossbeam 1, two supporting steels 2 are fixedly connected to the top of the crossbeam 1, the tops of the two supporting steels 2 are fixedly connected to hanging steels 3, the tops of the hanging steels 3 are fixedly connected to hanging rings 4, and the front and rear ends of the crossbeam 1 are installed with adjustment mechanisms 5, the adjustment mechanisms 5 include a support body 501 fixedly connected to the top of the crossbeam 1, a sliding groove 502 is opened inside the support body 501, a first motor 503 is fixedly connected to the top of the support body 501, a threaded rod 504 is fixedly connected to the output end of the first motor 503, a connector 505 is threadedly connected to the outer wall of the threaded rod 504, the front and rear ends of the connector 505 are rotatably connected to two arc-shaped supporting rods 506, and the front and rear ends of the crossbeam 1 are fixedly connected to a plurality of support seats 507, and the plurality of support seats 507 are all There are two connecting rods 508 rotatably connected, and a support block 509 is rotatably connected between each two arc-shaped support rods 506. Inner grooves 510 are opened inside the multiple support blocks 509, and the threaded rod 504 runs through the inside of the support body 501. The outer wall of the connecting body 505 is slidably connected to the sliding groove 502. The connecting body 505 is in the shape of four strips, and the other ends of each two connecting rods 508 are rotatably connected to the corresponding inner grooves 510 respectively. Each two connecting rods 508 are distributed up and down. When in use, when the metal sheet is transported, it is adjusted according to the width of the metal sheet. The width of the adsorption on the surface of the metal sheet can be controlled by the adjustment mechanism 5 to ensure that when the sheets of various sizes and widths are transported, the adsorption is controlled to the side of the metal sheet as much as possible, the swing of the sheet is reduced, and the sheet is prevented from being transported. When the metal sheet is transported, the lifting device is used to connect the lifting ring 4 on the top of the hanging steel 3 of the device. According to the width of the thin plate, the first motor 503 on the top of the support body 501 is started to drive the threaded rod 504 to rotate. At this time, the connecting body 505 is located at the top, and the metal sheet with the largest width can be transported. Then the connecting body 505 will move along with the rotation of the threaded rod 504. As the threaded rod 504 rotates, the connecting body 505 will move along the support body. The sliding groove 502 inside 501 moves downward, and under the traction of the two connecting rods 508 connected inside the support seat 507, multiple arc-shaped support rods 506 will converge to the middle and make a certain circular motion. At this time, the maximum width distance can be gradually reduced.

At this time, the arc-shaped support rod 506 will move to the maximum limit, and the support blocks 509 on both sides will converge in the center. At this time, the metal sheet of the smallest width can be handled. After the adsorption is completed, the lifting equipment is lifted to lift the handling device, thereby realizing the handling of metal sheets of different widths.

[0017] like Figure 6 As shown, an adsorption mechanism 6 is installed on the top of the beam 1, and the adsorption mechanism 6 includes a vacuum pump 601 fixedly connected to the top of the beam 1, and two first spring-type pipes 602 are fixedly connected to the top of the vacuum pump 601. A plurality of pipe buckles 603 are fixedly connected to the front and rear ends of the beam 1, and a straight pipe 604 is fixedly connected inside the plurality of pipe buckles 603. A plurality of connecting pipes 605 are fixedly connected to the top of the outer walls of the two straight pipes 604, wherein the input ends of the plurality of connecting pipes 605 are fixedly connected to the second spring-type pipes 606, and the input ends of the two first spring-type pipes 602 are fixedly connected to the corresponding connecting pipes 605, respectively. After selection according to the width of the metal sheet, the adsorption mechanism 6 can be used to adsorb the metal sheet. The metal sheet can be transported along with the movement of the transport device. At the same time, when the adsorption mechanism 6 is used to transport the metal sheet, the problem that metal sheets of different materials cannot be magnetized during transportation can be avoided. By using the adsorption mechanism 6, the contact area of ​​the suction cup 705 with the thin plate is larger, which can reduce local pressure and thus reduce potential damage to the surface of the thin plate. Specifically, after the width distance placement control is completed, the vacuum pump 601 on the top of the beam 1 is started at this time. The second spring-type pipe 606 connected to the multiple connecting pipes 605 through the two first spring-type pipes 602 can pass the gas through its interior, thereby realizing the suction force required for transporting the metal sheet, thereby ensuring that the surface force of the metal sheet is evenly applied during transportation.

[0018] like Figure 7As shown, a rotating mechanism 7 is installed on one side of the adjustment mechanism 5, and the rotating mechanism 7 includes a second motor 701 fixedly connected to one side of two support blocks 509, the output ends of the two second motors 701 are fixedly connected to the driving shaft 702, the other ends of the two driving shafts 702 are fixedly connected to the placement body 703, the inside of the placement body 703 is fixedly connected to the air intake pipe 704, the input end of the air intake pipe 704 is fixedly connected to the suction cup 705, the inside of the multiple support blocks 509 are rotatably connected to the connecting shaft 706, the input ends of the multiple second spring-type pipes 606 are respectively fixedly connected to the corresponding air intake pipe 704, the driving shaft 702 runs through the inside of the support block 509, and the ends of the multiple connecting shafts 706 are respectively connected to the corresponding placement bodies 70 3 is fixedly connected. When the adsorption mechanism 6 is started, the rotating mechanism 7 can be used to adsorb the metal sheet. At this time, the metal sheet can be transported. When some metal sheets are transported, the metal sheet can be kept standing on its side. By letting one side of the sheet stand up first, the operator can more conveniently adjust and position the sheet, which reduces the difficulty of operation. At the same time, when the metal sheet is standing on its side, the rotating mechanism 7 can be used to cooperate with the adjusting mechanism 5. It can be selected according to metal sheets of different thicknesses to improve the applicability of the transport device. At the same time, double-sided adsorption is used to ensure that the metal sheet is in a vertical state. The operator can better control the sheet to avoid accidental slipping and improve the safety of the operation. Specifically, the metal sheet needs to be transported flat. During operation, the surface of the metal sheet can be adsorbed by multiple suction cups 705, and the air inlet pipe 704 is connected to the input end of the second spring-type pipe 606 to generate suction, thereby realizing stable transportation of the metal sheet. At the same time, when the metal sheet is placed sideways, the adjustment mechanism 5 can be used to adjust the multiple suction cups 705 at one end of the beam 1 to adsorb the metal sheet. At this time, the lifting equipment will pull the transport device upward, and then start the second motor 701 on the side of the support block 509 to drive the drive shaft 702 to rotate. Since the multiple placement bodies 703 and the connecting shaft 706 are fixedly connected, the placement bodies 703 and the connecting shaft 706 will be driven to rotate, so that the suction cups 705 can rotate. When the metal sheet is placed sideways, the adjustment mechanism 5 can be used to adjust the multiple suction cups 705 at one end of the beam 1 to adsorb the metal sheet. At this time, the lifting equipment will pull the transport device upward, and then start the second motor 701 on the side of the support block 509 to drive the drive shaft 702 to rotate. Since the multiple placement bodies 703 and the connecting shaft 706 are fixedly connected, the placement bodies 703 and the connecting shaft 706 will be driven to rotate, so that the suction cups 705 can rotate. When the thin plate remains vertical at a certain level, the adjustment mechanism 5 can be used to adjust according to the thickness of the metal sheet, and the distance can be reduced to an appropriate distance according to the thickness of the metal sheet. At the same time, relevant adjustments can be made to ensure that the metal sheet has sufficient stability when being transported in a sideways state. Then, another second motor 701 is started until the multiple suction cups 705 at the other end of the beam 1 adsorb the other side of the metal sheet. At this time, the lifting equipment can be used to lift the thin plate to keep it in an upright state. The contact area is relatively small, which can reduce friction and damage to the surface of the thin plate. In addition, since the adjustment mechanism 5 will run in a circular arc when adjusting, the rotating mechanism 7 can be used to ensure the adsorption angle, thereby completing the transportation of the metal sheet.

[0019] The working principle of this embodiment is as follows. When the metal sheet is transported, the lifting equipment is used to connect with the lifting ring 4 at the top of the hanging steel 3 of this device. At this time, the first motor 503 at the top of the support body 501 is started to drive the threaded rod 504 to rotate. At this time, the connecting body 505 is at the top, and then the connecting body 505 will move along the rotation of the threaded rod 504. As the threaded rod 504 rotates, the connecting body 505 will move downward along the sliding groove 502 inside the support body 501, and the two connected inside the support seat 507 will be moved downward. Under the traction of the connecting rod 508, the multiple arc-shaped support rods 506 will converge to the middle until the connecting body 505 slides to a certain position of the support body 501. At this time, the arc-shaped support rods 506 will move to a certain position, and the support blocks 509 on both sides will remain stationary. At this time, the vacuum pump 601 on the top of the beam 1 is started. The second spring-shaped pipe 606 connected to the multiple connecting pipes 605 through the two first spring-shaped pipes 602 can pass the gas through it. The input end of the air inlet pipe 704 is fixedly connected to the suction cup 705 to absorb the metal sheet. At this time, the lifting The equipment can be used for lifting, driving the metal sheet in a flat state to move, and at the same time, another second motor 701 can be started until the multiple suction cups 705 at the other end of the beam 1 remain in a vertical state toward the bottom. When the metal sheet is placed sideways, the second motor 701 can be started to rotate, so that the suction cup 705 at one end of the beam 1 adjusts a certain angle, and the first motor 503 is started to make the support block 509 maintain a certain span, and then the multiple suction cups 705 at one end of the beam 1 adsorb the metal sheet, and cooperate with the lifting equipment to pull the moving piece upward. The transport device is then started, and the second motor 701 on one side of the support block 509 is started to drive the drive shaft 702 to rotate. Since the multiple placement bodies 703 and the connecting shaft 706 are fixedly connected, the placement bodies 703 and the connecting shaft 706 will be driven to rotate, so that the suction cup 705 can be rotated to ensure that when the metal sheet remains vertical, the adjustment mechanism 5 can be used for adjustment at this time, and another second motor 701 is started until the multiple suction cups 705 at the other end of the beam 1 adsorb the other side of the metal sheet, and then cooperate with the lifting equipment to complete the transportation of the metal sheet.
