Detailed implementation mode

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] Please refer to Figures 1-10 , the present invention provides a technical solution: a fully automatic hub conveyor line, including a support frame 1, on which a guide rail assembly 2 and a driving assembly 7 are arranged. A chain 6 is arranged directly below the guide rail assembly 2, and the driving assembly 7 is used to drive the chain 6 to operate; a plurality of support seats 4 are evenly distributed on the chain 6, and each support seat 4 is fixedly arranged on one section of the chain link of the chain 6. The support seat 4 is used to move along with the chain 6, and the support seat 4 moves along the guide rail assembly 2; a hub support mechanism 5 is arranged on each support seat 4, and the hub support mechanism 5 is used to support the electric tricycle hub to be conveyed (hereinafter referred to as the hub).

[0034] The hub support mechanism 5 includes two support assemblies 51, and both support assemblies 51 are rotatably arranged on the support seat 4; specifically, the support assembly 51 includes a support rod 511, the top of the support rod 511 is provided with a movable head 512, and a fixed shaft 513 is fixedly arranged on the movable head 512. The fixed shaft 513 passes through the movable head 512, and both ends of the fixed shaft 513 are movably connected to the support seat 4 through bearings.

[0035] The hub support mechanism 5 further includes a connecting member 52. One connecting member 52 is connected to the bottom end of each of the two support rods 511. An arc-shaped support bar 53 is arranged between the two connecting members 52, and the arc-shaped support bar 53 can be elastically deformed. A plurality of support pads 54 adapted to its structure are evenly distributed on the outer side of the arc-shaped support bar 53. The support pads 54 are used to cooperate with the middle groove of the hub and support the hub. The support pads 54 are fixedly arranged on the arc-shaped support bar 53. The plurality of support pads 54 are arranged along the length direction of the arc-shaped support bar 53. The support pads 54 can specifically be made of elastic materials such as silica gel or rubber.

[0036] The arc-shaped support bar 53 includes two outwardly convex support portions 531 arranged in parallel. An inwardly concave connecting portion 532 is arranged between the two outwardly convex support portions 531. At one end of each outwardly convex support portion 531 away from the inwardly concave connecting portion 532, a side wing portion 533 is respectively arranged. The two side wing portions 533, the two outwardly convex support portions 531, and an inwardly concave connecting portion 532 are an integrally formed structure. At the same time, when the arc-shaped support bar 53 is not deformed, the outwardly convex support portion 531 is tangent to the inwardly concave connecting portion 532, and the side wing portion 533 is tangent to the outwardly convex support portion 531 connected thereto, that is, as Figure 4 shown; The arc-shaped support bar 53 is made of a material with good elasticity, such as a metal alloy or spring steel with good elasticity.

[0037] The connecting member 52 includes a connecting block 521 fixed to the end of the arc-shaped support bar 53. The connecting block 521 can be set to be adapted to the structure of the arc-shaped support bar 53. A first connecting ring 522 is fixedly arranged on the connecting block 521. The connecting member 52 further includes a second connecting ring 523. The second connecting ring 523 is fixed to the bottom end of the support rod 511, and the first connecting ring 522 and the second connecting ring 523 are buckled with each other.

[0038] The guide rail assembly 2 includes an annular support plate 21 fixedly arranged on the support frame 1. An annular guide rail 22 is arranged at the bottom of the annular support plate 21. The annular guide rod is adapted to the annular structure formed by the chain 6. The guiding assembly 3 includes a bearing seat 31. The bearing seat 31 is fixedly connected to the support seat 4. Two rollers 32 are arranged on the bearing seat 31. The rollers 32 have their own rotating shafts, and the rotating shafts of the rollers 32 are movably connected to the bearing seat 31 through bearings. The two rollers 32 are both arranged to cooperate with the annular guide rail 22. When the driving assembly 7 drives the chain 6 to rotate, the bearing seat 31 can be driven to move cyclically along the length direction of the annular guide rail 22.

[0039] In this embodiment, the hub support mechanism 5 is used to support the hub, that is, the hub is placed on the support pad 54. Specifically, the hub can be clamped by an external manipulator or placed manually. The driving component 7 drives the chain 6 to move, and further drives the hub support mechanism 5 to move, and the entire conveyor line forms a suspension conveyor line. When the hub is conveyed to the designated position, it cooperates with the external manipulator to clamp the hub or take out the hub manually, so that the hub can be removed from the hub support mechanism 5. When the external manipulator clamps the hub, it clamps the part of the hub near the end, and the arc-shaped support strip 53 will not interfere with the clamping operation of the external manipulator.

[0040] In this embodiment, the hub support mechanism 5 before placing the hub is as Figure 5 shown; after placing the hub, due to the action of gravity, the downward pressure causes the arc-shaped support strip 53 to deform, prompting the middle position of the arc-shaped support strip 53 to deform into an arc shape adapted to the hub, that is, as Figure 6 shown; at the same time, when the hub is placed, the support pad 54 is used to be clamped in the groove in the middle of the hub, and the support pad 54 will also deform. In addition, the two side wing parts 533 deform in the direction close to the concave connecting part 532, and the shapes of the convex support part 531, the concave connecting part 532 and the side wing parts 533 will all deform. Since the arc-shaped support strip 53 has good elasticity, it helps to prompt the support pad 54 to press against the two opposite side walls of the groove in the middle of the hub, thereby improving the stability of the hub placement. In addition, by supporting the hub with the hub support mechanism 5, compared with the traditional rod-shaped structure for supporting the hub, the support area is large and the support effect is improved. At the same time, using the support pad 54 to support the hub can also reduce the wear of the hub during the conveying process.

[0041] In this embodiment, a limit seat 8 is respectively arranged on each support seat 4. The limit seat 8 has an inverted U-shaped structure, and limit parts 81 are integrally formed on the outer walls of both sides of the limit seat 8. The two limit parts 81 corresponding to each support seat 4 are located between the two movable heads 512 corresponding to the support seat 4. When a hub is placed on the hub support mechanism 5, the two support rods 511 are in a vertical state, and the two movable heads 512 corresponding to each support seat 4 respectively contact the two limit parts 81 corresponding to the support seat 4. By the limit parts 81 abutting against the corresponding movable heads 512, it is used to limit the movable heads 512. That is, when the movable head 512 contacts the limit part 81, the movable head 512 can only rotate in the direction away from the movable head 512.

[0042] When removing the wheel hub, the external manipulator or manual labor first picks up the wheel hub upward. Since the arc-shaped support bar 53 undergoes elastic deformation, during the process of lifting the wheel hub upward, the arc-shaped support bar 53 will reset. At the same time, due to the limiting effect of the limiting portion 81 on the movable head 512, the movable head 512 is prompted to rotate in a direction away from the corresponding limiting portion 81, facilitating the two support rods 511 to open to form a V-shaped structure. The bottom of the support rod 511, the end of the arc-shaped support bar 53, and the connecting member 52 gradually move away from the wheel hub, thereby helping to increase the operating space for the external manipulator or manual labor. When the wheel hub is lifted upward by an appropriate displacement, it is convenient to horizontally move the wheel hub, thereby improving the efficiency of removing the wheel hub.

[0043] Embodiment Two

[0044] Please refer to Figure 11 , based on Embodiment One, a plurality of reset components 9 are evenly distributed between the two side wing portions 533. The reset component 9 includes two fixed heads 91, which are respectively fixedly arranged on the two side wing portions 533. The positions of the two fixed heads 91 do not correspond, and a tension spring 92 is connected between the two fixed heads 91.

[0045] After placing the wheel hub, the arc-shaped support bar 53 deforms, further causing the tension spring 92 to deform. By setting the tension spring 92, it is further convenient for the arc-shaped support bar 53 to reset.

[0046] Embodiment Three

[0047] Please refer to Figures 1-12 , based on Embodiment Two, the driving component 7 includes a driving shaft 71 and a driven shaft 73. The driving shaft 71 and the driven shaft 73 are respectively movably connected to the support frame 1 through bearings. An active sprocket 72 is fixedly sleeved on the outside of the driving shaft 71, and a driven sprocket 74 is fixedly sleeved on the outside of the driven shaft 73. Both the active sprocket 72 and the driven sprocket 74 are engaged with the chain 6. At the same time, a driving motor 75 is installed on the support frame 1, and the output shaft of the driving motor 75 is fixedly connected to the driving shaft 71, and the output shaft of the driving motor 75 is coaxial with the driving shaft 71.

[0048] The driving motor 75 drives the driving shaft 71 to rotate, the driving shaft 71 drives the active sprocket 72 to rotate, and with the cooperation of the driven sprocket 74, the chain 6 can be driven to operate, further driving the support seat 4, the wheel hub support mechanism 5, and the wheel hub to move, realizing the automatic conveying of the wheel hub.
