[0027] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] like Figures 1 to 6 As shown, this utility model embodiment provides a conveying device, which includes: a magnetic drive mechanism 2, a support mechanism 3, and a supporting structure 4; multiple supporting structures 4 are provided, and all supporting structures 4 are spaced apart along the conveying direction of the conveying device; each supporting structure 4 has a magnetic element 43 at both ends; the magnetic drive mechanism 2 is arranged in a one-to-one correspondence with the magnetic element 43, and the magnetic drive mechanism 2 is arranged opposite to the corresponding magnetic element 43 and can generate a magnetic attraction force with the corresponding magnetic element 43; the support mechanism 3 is arranged in a one-to-one correspondence with the magnetic drive mechanism 2, and the magnetic drive mechanism 2 is installed on the corresponding supporting structure 4. When the supporting structure 4 moves under the action of an external force, the magnetic drive mechanism 2 can move with the supporting structure 4 within the corresponding support mechanism 3.

[0029] The conveying device provided in this embodiment is used to convey workpieces, which can move within the conveying device along the conveying direction. Optionally, the workpiece can be sheet metal, such as steel plate, or uncoiled coil strip, or workpieces such as wheel hubs. All supporting structures 4 are arranged sequentially at intervals along the conveying direction of the conveying device to support the conveyed workpieces. Optionally, the conveying device has a supporting frame 1, which is the main supporting structure of the conveying device. It includes at least two opposing frame main plates 11. The area between the two frame main plates 11 is the interior of the supporting frame 1, and the area away from the frame main plates 11 is the exterior of the supporting frame 1. The frame main plates 11 extend along the conveying direction of the conveying device, and the supporting structure 4 is located between the two frame main plates 11, preferably perpendicular to the frame main plates 11. Magnetic elements 43 are provided at both ends of the supporting structure 4. To protect the magnetic elements 43, they are preferably located inside the supporting structure 4. The magnetic elements 43 are preferably permanent magnets, so that there is no need to set up circuit-related structures inside the supporting structure 4. Of course, the magnetic elements 43 can also be electromagnets. Each magnetic component 43 is provided with a corresponding magnetic drive mechanism 2. The magnetic drive mechanism 2 is arranged opposite to the corresponding magnetic component 43, and the magnetic drive mechanism 2 can generate a magnetic attraction force with the corresponding magnetic component 43. Under the action of the magnetic attraction force between the magnetic components 43 at both ends of the supporting structure 4 and the corresponding magnetic drive mechanism 2, the supporting structure 4 can overcome its own gravity and thus move in a suspended form within the supporting frame 1. The magnetic drive mechanism 2 is preferably an electromagnet. Compared with the use of permanent magnets, the use of electromagnets in the magnetic drive mechanism 2 can adjust the magnetic attraction force between the magnetic drive mechanism 2 and the magnetic component 43, thereby adjusting the supporting force of the supporting structure 4. Each magnetic drive mechanism 2 is equipped with a support mechanism 3, which is used to support the corresponding magnetic drive mechanism 2, and the magnetic drive mechanism 2 can float within the support mechanism 3. In use, when a workpiece is being transported passes through the support structure 4, the support structure 4 will move downward under the gravity of the workpiece. Meanwhile, the magnetic drive mechanisms 2 at both ends of the support structure 4 will move synchronously with the support structure 4 within the support mechanism 3 to ensure that the support structure 4 can always remain suspended. When the workpiece leaves the support structure 4, the support structure 4 and the magnetic drive mechanism 2 will reset synchronously under the action of the support mechanism 3, that is, return to the position when the workpiece did not pass through.

[0030] The conveying device provided in this embodiment has magnetic components 43 with magnetic properties at both ends of the supporting structure 4, and each magnetic component 43 is equipped with a magnetic drive mechanism 2. During operation, the supporting structure 4 can be suspended under the action of the magnetic components 43 and the magnetic drive mechanism 2. With the support mechanism 3 used to support the magnetic drive mechanism 2, the supporting structure 4 will adaptively adjust its position when the conveyed workpiece passes through it. Compared with the prior art, this can reduce the wear and tear on the supporting structure 4 and improve its service life.

[0031] Moreover, since the supporting structure 4 is suspended within the support frame 1 under the action of the magnetic component 43 and the magnetic drive mechanism 2, the supporting structure 4 is installed within the support frame 1 in a non-physical connection manner. Therefore, there is no need to set up bearings or sealing structures between the support frame 1 and the supporting structure 4, which can reduce the workload during manufacturing and avoid problems such as bearing jamming, seal failure and internal leakage.

[0032] As a preferred option, such as Figure 1 and Figure 4 As shown, the magnetic drive mechanism 2 and the corresponding support mechanism 3 are located outside the support frame 1, thereby preventing impurities from interfering with the magnetic drive mechanism 2 and the support mechanism 3 during the operation of the conveying device, thus providing a certain degree of protection for the magnetic drive mechanism 2 and the support mechanism 3 and extending their service life.

[0033] The conveying device provided in this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the support mechanism 3 includes a fixing member 31 and multiple buffer members 32; the fixing member 31 is fixedly installed, one end of the buffer member 32 is connected to the fixing member 31, and the other end is connected to the corresponding magnetic drive mechanism 2, and all the buffer members 32 are spaced apart along the periphery of the magnetic drive mechanism 2.

[0034] In this embodiment, the magnetic drive mechanism 2 described above moves synchronously with the supporting structure 4 under the action of the buffer 32. The fixing member 31 can be a block structure, in which case multiple fixing members 31 are provided, each corresponding to one of the buffer members 32. The fixing member 31 can also be a frame structure such as a circular ring, elliptical ring, or square, in which case only one fixing member 31 is required. The fixing member 31 is fixedly installed, and all buffer members 32 are fixedly connected to the fixing member 31 at one end and connected to the magnetic drive mechanism 2 at the other end.

[0035] Optionally, in this embodiment, the buffer 32 can be a spring, which has a simple structure, low cost, and long service life; or, the buffer 32 can also be a hydraulic component, which is a device that uses liquid as a working medium to absorb and dissipate energy through the flow resistance of the liquid, and can also achieve the purpose of enabling the magnetic drive mechanism 2 to move synchronously with the support structure 4 in this embodiment.

[0036] The aforementioned fastener 31 can be fixed in the form of a support or other structure inside the conveying device, with the fastener 31 fixed on the support inside the conveying device. Alternatively, the fastener 31 can be directly fixed to the frame main board 11 of the support frame 1 by welding, riveting, or screwing. Preferably, the fastener 31 is fixed to the outside of the frame main board 11.

[0037] The conveying device provided in this embodiment of the utility model, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, it also includes multiple limiting members 12, and both ends of the supporting structure 4 are provided with limiting members 12; the limiting members 12 are fixed to the inner side of the supporting frame 1, and the limiting members 12 have limiting holes and / or limiting grooves, so that the ends of the supporting structure 4 can pass through the corresponding limiting members 12.

[0038] In this embodiment, to prevent excessive downward displacement of the support structure 4 due to the excessive mass of the workpiece during operation, which could lead to disengagement of the support structure 4 from the corresponding magnetic drive mechanism 2 and cause the support structure 4 to detach from the support frame 1, the support structure 4 is also equipped with limiting members 12. Each end of the support structure 4 is equipped with a limiting member 12, which is a ring-shaped or square cylindrical structure, a semi-circular groove structure, or a hole opened on the frame main plate 11. Preferably, the limiting member 12 adopts the aforementioned cylindrical structure. Correspondingly, the limiting member 12 has a limiting hole. One end of the limiting member 12 can be fixed to the inner side of the frame main plate 11 by welding, riveting, or screwing, and the end of the support structure 4 passes through the limiting member 12 at the end facing away from the frame main plate 11. Thus, when the workpiece passes through the support structure 4, the support structure 4 can only move within the workpiece, preventing disengagement from the magnetic drive mechanism.

[0039] Moreover, the magnetic drive mechanism 2 mentioned above is preferably an electromagnet. In this way, when the conveying device is not in use and the power to the conveying device is cut off, the supporting structure 4 will not fall off. When the conveying device is activated and the electromagnet is powered on, the supporting structure 4 can be re-levitated.

[0040] Alternatively, in this embodiment, when the conveyed workpiece is a strip, such as a steel strip after a steel coil has been uncoiled, after the head of the steel strip is put into and passes through the conveying device, since the steel strip is continuous, the remaining middle part of the steel strip does not need to be supported and conveyed, and can also pass through the conveying device. Therefore, the conveying device does not need to work at this time, and the supporting structure 4 can be lowered directly. When the supporting structure 4 is a support roller 41, since the steel strip does not contact the support roller 41, the support roller 41 does not need to rotate, thereby achieving the effect of energy saving and simplified control.

[0041] When the aforementioned limiting member 12 has a cylindrical structure, in order to facilitate the installation of the limiting member 12, preferably, the limiting member 12 adopts a multi-lobed structure. During assembly, the supporting structure 4 is first placed in the preset position, and then the limiting member 12 is installed.

[0042] The aforementioned supporting structure 4 has various forms, including, in one embodiment of the supporting structure 4, such as... Figures 1 to 3 As shown, the aforementioned support structure 4 is a support roller 41, which is a cylindrical structure with annular permanent magnets at both ends serving as magnetic components 43. The limiting component 12, which cooperates with the support roller 41, is a circular cylindrical structure. Preferably, the support roller 41 needs to rotate during operation of the conveying device to reduce wear. Therefore, the aforementioned magnetic drive mechanism 2 is preferably equipped with a structure such as a commutator to switch the magnetic poles, enabling the support roller 41 to rotate, thereby preventing the magnetic drive mechanism 2 from affecting the rotation of the support roller 41 during operation.

[0043] It should be noted that the rotation of the support roller 41 is generally passive rotation, that is, it rotates under the action of the moving workpiece.

[0044] Preferably, the electromagnet is also ring-shaped. In this case, the buffer 32 of the support mechanism 3 can be evenly distributed along the circumference of the electromagnet. Preferably, four buffers 32 are provided, with an included angle of 90° between two adjacent buffers 32, and two of the buffers 32 are vertically arranged and the other two are horizontally arranged.

[0045] Optionally, in this embodiment, when the supporting structure 4 is a supporting roller 41, the magnetic drive mechanism 2 can also be a permanent magnet. In this case, the permanent magnet needs to be ring-shaped and a cover needs to be provided. The permanent magnet is rotatably located inside the cover, and the cover is used to connect with the above-mentioned support mechanism 3. When the conveying device is running, the permanent magnet rotates with the supporting roller 41.

[0046] In another embodiment of the supporting structure 4, such as Figures 4 to 6 As shown, the supporting structure 4 includes a supporting plate 421 and a mounting component 422; magnetic components 43 are provided at both ends of the mounting component 422, and the supporting plate 421 is provided on the mounting component 422.

[0047] In this embodiment, the support plate 421 is used to support the workpiece during the workpiece conveying process and prevent the workpiece head from falling. In order to improve the support effect and save costs, multiple support plates 421 are preferably provided. Of course, the support plate 421 can also be a long strip plate provided between two frame main plates 11. The support plate 421 is installed in the support frame 1 by the mounting member 422. The mounting member 422 has a beam-like structure and can be a whole beam. When multiple support plates 421 are provided, all support plates 421 are arranged sequentially and spaced on the support beam. The magnetic element 43 is located inside both ends of the mounting member 422. The mounting member 422 can be a multi-segment beam. Two adjacent support plates 421 are connected by the mounting member 422. The support plates 421 at both ends are also provided with mounting members 422 for setting the aforementioned magnetic element 43.

[0048] Optionally, in this embodiment, when the support structure 4 includes a support plate 421 and a mounting member 422, the support plate 421 does not need to rotate. Thus, the limiting member 12 can be a square frame, and the mounting member 422 can be a corresponding square beam.

[0049] Furthermore, when the aforementioned mounting component 422 is a square beam, the magnetic component 43 is square, the electromagnet is also oriented accordingly, and at least one buffer component 32 is provided on each side of the electromagnet.

[0050] Preferably, the conveying device provided in this embodiment has multiple supporting structures 4, which are combinations of supporting rollers 41 and supporting plates 421. The supporting rollers 41 may optionally be equipped with structures such as motors to drive their rotation, thereby providing power for workpiece conveying. Of course, for conveying sheet materials (including sheet metal and uncoiled strip), a dedicated power roller is usually provided to drive the sheet material's movement, thus eliminating the need for a motor on the supporting rollers 41. The supporting plates 421 are positioned between adjacent supporting rollers 41 to prevent the head or tail of the workpiece from falling when it moves between adjacent supporting rollers 41. Furthermore, at least one set of supporting plates 421 is arranged between adjacent supporting rollers 41 along the material conveying direction.

[0051] In this embodiment, the support plate 421 is generally inclined upward along the conveying direction of the conveying device. The distance between the higher end of the support plate 421 and the conveyed workpiece is the minimum distance between the support plate 421 and the conveyed workpiece. Preferably, the minimum distance between the support plate 421 and the conveyed workpiece is greater than or equal to 5mm, so as to prevent the head or tail of the conveyed workpiece from falling into the area between two adjacent support rollers 41, while also avoiding collision between the conveyed workpiece and the support plate 421 and generating unnecessary resistance, or avoiding defects such as scratches on the surface of the conveyed workpiece.

[0052] The conveying device provided in this embodiment also includes a controller. The magnetic drive mechanism 2 corresponding to the magnetic component 43 of each supporting structure 4 is an electromagnet. Each electromagnet is electrically connected to the controller. The controller can control the on and off of the electromagnet based on the size information of the conveyed workpiece and / or through the information.

[0053] For example, when the head of the conveyed workpiece passes through the support plate 421, the controller can control the corresponding magnetic drive mechanism 2 to de-energize, and the support plate 421 falls and does not participate in the conveying. In this way, the distance between the support plate 421 and the conveyed workpiece can be greater, so as to avoid the conveyed workpiece hitting the support plate 421, causing damage between the conveyed workpiece and the support plate 421, or generating unnecessary conveying resistance.

[0054] Alternatively, when the workpiece being conveyed is a steel plate, if the thickness of the steel plate is greater than or equal to 15mm, the two magnetic drive mechanisms 2 corresponding to the support roller 41 at the starting position are always energized along the conveying direction of the conveying device to keep the steel plate stable; if the thickness of the steel plate is less than 15mm and the length is less than or equal to 5m, the magnetic drive mechanisms 2 corresponding to at least two support rollers 41 in the middle section are always energized to prevent the steel plate from deviating; if the thickness of the steel plate is less than 15mm and the length is greater than 5m, the magnetic drive mechanisms 2 corresponding to at least two support rollers 41 can be de-energized to reduce the wear of the support rollers 41 and reduce production costs.

[0055] Another embodiment of this utility model provides a production device, including the conveying device described in any of the above embodiments.

[0056] Optionally, the aforementioned production equipment can be sheet metal processing equipment, wheel hub processing equipment, or other production equipment that requires surface treatment, such as fenders or door panels, or other production equipment involving workpiece conveying.

[0057] When the aforementioned production equipment is sheet metal processing equipment, it is used to remove oxide scale from the surface of the sheet metal, and the conveying device is used to transport the sheet metal. When the conveying device transports the sheet metal, since the supporting structure 4 does not require physical connection, there will be no leakage of working fluid, solid particles, or other impurities inside the equipment. Moreover, when sheet metal such as steel plates, steel strips, or other alloy plates and strips is being transported, after the sheet metal is threaded and the entire line is tightened, the supporting structure 4 no longer needs to be supported, and the electromagnet can be directly de-energized, saving energy and increasing the service life of the supporting structure 4.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
