[0022] The present invention will be further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 A large-scale roller assembly production line includes a ground rail 10, one end of which is provided with a fixed chuck 11 for clamping a central shaft 81, a first supporting assembly 20 and a second supporting assembly 30 are slidably provided on the ground rail 10, the first supporting assembly 20 is used to place the drum skin 80, the second supporting assembly 30 is used to place the central shaft 81, and the second supporting assembly 30 is located between the first supporting assembly 20 and the fixed chuck 11.

[0024] The first supporting assembly 20 and the second supporting assembly 30 are both moved along the ground rail 10 through the moving assembly 70. A rack 12 is provided on the surface of the ground rail 10. The moving assembly 70 includes a moving motor 71 and a moving gear 72. The moving gear 72 is meshed with the rack 12, and the moving motor 71 drives the moving gear 72 to rotate.

[0025] The first supporting assembly 20 and the second supporting assembly 30 have the same structure. The first supporting assembly 20 includes a sliding plate 21, a worm gear hoist 23 and a limit seat 22. The sliding plate 21 is slidably connected to the ground rail 10. The worm gear hoist 23 is arranged above the sliding plate 21. The limit seat 22 is fixedly connected to the worm gear hoist. The worm gear hoist 23 drives the limit seat 22 to move up and down. A V-shaped groove is provided on the surface of the limit seat 22.

[0026] When the tube skin 80 and the center axis 81 are placed on the limit seat 22, the structure of the surface of the limit seat 22 is used to ensure that the tube skin 80 and the center axis 81 are located in the middle of the limit seat 22, and the limit seat 22 is lifted by the worm gear lifting machine 23, so that the axes of the tube skin 80 and the center axis 81 on the first supporting component 20 and the second supporting component 30 are located on the same straight line, ensuring the subsequent assembly accuracy, and adjusting the center axis 81 to a height at which the fixed chuck 11 can be fixed, and there are four worm gear lifting machines 23 on the first supporting component 20, which are correspondingly arranged at the four corners of the limit seat 22, to ensure that the heavier tube skin 80 can be lifted smoothly.

[0027] The transporting assembly 40 includes two groups of transporting assemblies 40 , which are disposed on one side of the ground rail 10 . The transporting assemblies 40 are used to roll the tube skin 80 and the central axis 81 onto the first supporting assembly 20 and the second supporting assembly 30 , respectively.

[0028] The docking assembly 50 is arranged on the other side of the ground rail 10 relative to the conveying assembly 40, and the docking assembly 50 is arranged corresponding to the conveying assembly 40. The docking assembly 50 is used to limit the position when the conveying assembly 40 conveys the cylinder skin 80 or the central axis 81 to the first supporting assembly 20 and the second assembly, and the docking assembly 50 is also used to transfer the assembled roller to the next process.

[0029] Please refer to Figure 5 The docking assembly 50 includes a double arm 51, a single arm 52 and a support 53. A moving wheel is provided below the support 53. A track 54 is provided below the support 53. The track 54 is arranged between the ground rail 10 and the blanking assembly 60. The support 53 can move along the track 54. The double arm 51 is in a U-shaped structure. One side of the double arm 51 is rotatably connected to the side of the support 53 close to the ground rail 10. A limit block 511 is provided below the side of the double arm 51 close to the support 53. The limit block 511 is used to limit the double arm 51 from rotating downward, and the length of the double arm 51 is greater than the width of the ground rail 10. The single arm 52 is rotatably connected to the other side of the support 53. A storage groove is provided on the surface of the support 53, and the single arm 52 can be received in the storage groove. The double arm 51 and the single arm 52 are both controlled to rotate by a rotating motor, and the surfaces of the double arm 51, the single arm 52 and the support 53 are all in an inverted triangular inclined structure.

[0030] In the initial state, the single arm 52 of the docking assembly 50 is stored in the storage groove of the support 53, and the double arm 51 is unfolded toward one side of the ground rail 10, and is restricted to maintain a horizontal state by the limit block 511 below the double arm 51. The double arm 51 is inserted into both sides of the limit seat 22 of the first supporting assembly 20 or the second supporting assembly 30 through the moving wheel, and the limit seat 22 is assisted to unload the impact force of the tube skin 80 and the central axis 81 when they roll down. When the tube skin 80 or the central axis 81 rolls toward the double arm 51, the single arm 52 can be lifted slightly to prevent the tube skin 80 or the central axis 81 from rolling, and then the double arm 51 is withdrawn from both sides of the limit seat 22. When it is necessary to remove the assembled tube skin 80 from the limiting seat 22, the double support arms 51 are reinserted into both sides of the limiting seat 22, and the double support arms 51 are driven to rotate toward the side of the support 53 by controlling the rotating motor, so that the tube skin 80 is transferred to the support 53, and then transferred to the next process using the single support arm 52 on the support 53.

[0031] In addition, the surfaces of the double arm 51, the single arm 52 and the support 53 are all inverted triangular inclined structures, which can better limit the tube skin 80 and the central axis 81. A lifting cylinder 13 is provided on the side of the ground rail 10 away from the docking assembly 50. The lifting cylinder 13 is arranged corresponding to the docking assembly 50, and the double arm 51 can be erected above the lifting cylinder 13. The lifting cylinder 13 can be used to better support the side of the double arm 51 away from the support 53, thereby improving the overall unloading effect.

[0032] The unloading assembly 60 is arranged on a side of the docking assembly 50 away from the ground rail 10 , and is used to receive the assembled roller carried by the docking assembly 50 .

[0033] Please refer to Figure 4 The transport assembly 40 has the same structure as the unloading assembly 60. The transport assembly 40 includes a support frame 41, which is tilted downward toward the ground rail 10. A fixed frame 42 is provided in the middle of the support frame 41. A plurality of stoppers 43 are provided in the middle of the fixed frame 42. The plurality of stoppers 43 are arranged at intervals along the extending direction of the fixed frame 42. The stoppers 43 include two T-shaped plates 431, two rollers 432 and a slider 433. The two T-shaped plates 431 are arranged opposite to each other. The two rollers 432 are arranged at two ends. The two rollers 432 are respectively located at opposite ends of the T-shaped plate 431, and the other end of the T-shaped plate 431 is rotatably connected to the inner side of the fixed frame 42. The slider 433 is arranged below the roller 432, and the contact surface between the slider 433 and the roller 432 is an inclined structure. A slide rail 434 is provided below the slider 433, and the slider 433 slides along the slide rail 434, so as to push the roller 432 on the other side of the T-shaped plate 431 out of the fixed frame 42 or drop it into the fixed frame 42.

[0034] Each cylinder skin 80 or center shaft 81 is placed between two stoppers 43, and the stoppers 43 are used to limit the rolling of the cylinder skin 80 or center shaft 81. When the stoppers 43 need to stop the cylinder skin 80 or center shaft 81 from rolling, the high part of the inclined surface of the slider 433 contacts the roller 432 at the lower end of the T-shaped plate 431, so that the roller 432 on the T-shaped plate 431 is pushed out of the fixed frame 42, thereby playing a limiting role. When the cylinder skin 80 or center shaft 81 needs to move along the support frame 41, , the slider 433 is pushed to slide toward the far side, so that the lower part of the inclined surface of the slider 433 contacts the roller 432 at the lower end of the T-plate 431, and the T-plate 431 rotates downward, so that the roller 432 at the upper end of the T-plate 431 is stored under the fixed frame 42, so that the tube skin 80 or the central axis 81 can roll smoothly along the support frame 41 for subsequent processing, and by controlling multiple sliders 433 in linkage, multiple tube skins 80 or central axes 81 can roll synchronously.

[0035] And because the diameter of the tube skin 80 is relatively large, multiple limit members 43 can be set at intervals, that is, the raised T-shaped plates 431 and the lowered T-shaped plates 431 are set alternately, that is, when one limit member 43 is in a raised state, the two adjacent limit members 43 are in a lowered state, thereby decomposing the rolling process of the tube skin 80 into two sections, while also satisfying the larger interval setting of the diameter of the tube skin 80.

[0036] Working principle: hoist multiple tube skins 80 or central shafts 81 to the corresponding transport components 40 in sequence by hoisting, and use the limiting member 43 of the transport component 40 to sequentially space the multiple tube skins 80 or central shafts 81, which also plays a role of limiting. The support frame 41 for the transport component 40 is tilted downward toward the side of the ground rail 10, so that the tube skin 80 and the central shaft 81 maintain a rolling trend toward the ground rail 10; move the first supporting component 20 and the second supporting component 30 to the corresponding transport component 40 through the moving component 70. After the first supporting component 20 and the second supporting component 30 are moved into place, the connecting component 50 also corresponds to the first The supporting assembly 20 and the second supporting assembly 30 are moved into place. At this time, the limiting member 43 on the conveying assembly 40 that limits the tube skin 80 and the central axis 81 descends, so that the tube skin 80 and the central axis 81 roll to the first supporting assembly 20 and the second supporting assembly 30 on the ground rail 10 under the action of gravity. The connecting assembly 50 is used to guide and limit the tube skin 80 and the central axis 81. After the tube skin 80 and the central axis 81 complete the placement of the first supporting assembly 20 and the second supporting assembly 30, the connecting assembly 50 is withdrawn in the direction away from the ground rail 10, and moves along the ground rail 10 through the first supporting assembly 20 and the second supporting assembly 30 to complete the assembly operation. After the tube skin 80 and the central axis 81 are assembled, the first supporting assembly 20 drives the tube skin 80 to move to the corresponding position of the blanking assembly 60, and the double arms 51 of the connecting assembly 50 are reinserted into the two sides of the first supporting assembly 20. By controlling the double arms 51 to rotate toward the side of the support 53, the tube skin 80 on the first supporting assembly 20 is pushed toward the support 53, so that the tube skin 80 rolls along the double arms 51, and the inverted triangular inclined surface structure on the support 53 can limit the rolling range of the tube skin 80, while ensuring that it is located on the support 53. After the tube skin 80 is placed on the support 53, the connecting assembly 50 moves to one side of the blanking assembly 60, and uses the single arm 52 to rotate toward the side away from the support 53, so that the tube skin 80 on the support 53 is pushed to the support frame 41 of the blanking assembly 60, and enters the next process.

[0037] Through the above structure, it is only necessary to hoist the tube skin 80 and the central axis 81 onto the conveying assembly 40, and perform subsequent automated assembly and unloading through the conveying assembly 40, thereby improving assembly efficiency and reducing the occurrence of dangerous situations during the assembly process.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
