Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to a material roll transfer device and a cantilever mechanism. Background Technology

[0002] In industrial production, such as battery manufacturing, the handling of material rolls is a frequent task. Currently, the common method is to install a cantilever structure on an automated guided vehicle (AGV), and the material rolls are transferred by placing them on the cantilever. After the material rolls are transported to the target workstation, they are usually unloaded from the cantilever manually or with lifting equipment. However, when the material rolls are heavy, conventional unloading methods become difficult to operate, inefficient, and pose certain safety risks. Utility Model Content

[0003] Therefore, it is necessary to provide a material roll transfer device and cantilever mechanism that facilitates unloading of material rolls to address the above problems.

[0004] A cantilever mechanism, comprising:

[0005] Base;

[0006] A support shaft is fixed to the base. The surface of the support shaft is provided with multiple rows of rolling elements spaced apart circumferentially along the support shaft, and each row of rolling elements extends axially along the support shaft.

[0007] A pusher sleeve, fitted onto the support shaft and capable of moving axially along the support shaft; and

[0008] The drive assembly is connected to the pusher sleeve and is capable of driving the pusher sleeve to move axially along the support shaft.

[0009] In one embodiment, a limiting block is provided at one end of the support shaft away from the base. The limiting block is operable to switch positions so that it protrudes or retracts relative to the surface of the support shaft.

[0010] In one embodiment, the rolling element is configured as a ball embedded in the support shaft, and the ball portion protrudes from the surface of the support shaft.

[0011] In one embodiment, a plurality of pressure plates are arranged circumferentially along the support shaft, each pressure plate being detachably mounted to the support shaft, and each row of balls being held by one of the pressure plates on the support shaft.

[0012] In one embodiment, a plurality of rollers are installed at circumferential intervals on the inner wall of the pusher sleeve, and the rollers abut against the surface of the support shaft so that the pusher sleeve can move axially along the support shaft.

[0013] In one embodiment, the inner wall of the pusher sleeve is provided with a plurality of brackets spaced circumferentially along the pusher sleeve, and each bracket is provided with two rollers, the two rollers being arranged at an angle.

[0014] In one embodiment, the drive assembly includes a drive motor and a ring-shaped transmission chain, the transmission chain being sleeved on the rotating end of the drive motor and extending axially along the support shaft, and the inner wall of the pusher sleeve being connected to the transmission chain.

[0015] In one embodiment, the support shaft has a hollow structure, and a window is provided at the end of the support shaft away from the base, through which the transmission chain passes so that a portion of the transmission chain passes through the interior of the support shaft.

[0016] In one embodiment, a clearance hole is formed on the base, the drive motor is disposed on the side of the base facing away from the base, and the transmission chain passes through the clearance hole.

[0017] A roll transfer device includes an automated guided vehicle and a cantilever mechanism as described in any of the preferred embodiments above, the cantilever mechanism being mounted on the automated guided vehicle.

[0018] In the aforementioned coil transfer device and cantilever mechanism, the coil is first placed on a support shaft during transfer. As the automated guided vehicle moves, the coil is transported to the target location. Once the coil is in place, the drive assembly first drives the pusher sleeve to move outward along the support shaft, thereby applying a pushing force to the coil. Because the inner wall of the coil is in direct contact with the rolling elements, the friction between the coil and the support shaft is relatively small. Therefore, under the pushing force of the pusher sleeve, the coil can move axially towards the end of the support shaft until it slides off the end of the support shaft to complete unloading. It is evident that during the unloading process, the aforementioned coil transfer device and cantilever mechanism can automatically perform the relevant operations without manual intervention, thus making the unloading operation of the coil more convenient.

[0030] Please see Figure 1 This utility model provides a cantilever mechanism 10. Furthermore, this utility model also provides a material roll transfer device, wherein the material roll transfer device includes an automatic guide vehicle (not shown) and the cantilever mechanism 10.

[0031] The aforementioned roll transfer device is used to transfer rolls 20, such as diaphragm rolls, electrode rolls, etc. A cantilever mechanism 10 is mounted on the automated guided vehicle (AGV). Furthermore, the cantilever mechanism 10 supports the roll 20. The AGV can then travel along a planned path, transporting the roll 20 to the target location as it moves.

[0032] Please refer to the following: Figure 2 and Figure 3 In one embodiment of the present invention, the cantilever mechanism 10 includes a base 100, a support shaft 200, a pusher sleeve 300, and a drive assembly 400.

[0033] The base 100 provides support and can be connected to the automated guided vehicle. The support shaft 200 is fixed to the base 100. The base 100 is generally also equipped with a connecting flange, and one end of the support shaft 200 can be fixedly connected to the base 100 through the connecting flange and threaded fasteners.

[0034] The support shaft 200 is elongated and supports the material roll 20. The material roll 20 to be transferred is first fitted onto the support shaft 200. Multiple rows of rolling elements 210 are arranged on the surface of the support shaft 200, spaced apart circumferentially, with each row extending axially along the support shaft 200. Each row of rolling elements 210 typically contains multiple spaced-apart rolling elements 210 capable of rolling. The top of each rolling element 210 protrudes from the surface of the support shaft 200, thus the material roll 20 fitted onto the support shaft 200 will directly contact the rolling element 210.

[0035] Specifically, in this embodiment, the rolling element 210 is configured as a ball embedded in the support shaft 200, with the ball portion protruding from the surface of the support shaft 200. The ball is spherical in shape, providing high support strength and resistance to deformation. Moreover, the ball can roll in any direction, requiring lower installation precision.

[0036] Furthermore, in this embodiment, a plurality of pressure plates 220 are arranged at circumferential intervals along the support shaft 200. Each pressure plate 220 is detachably installed on the support shaft 200, and each row of balls is pressed against the support shaft 200 by a pressure plate 220.

[0037] More specifically, the pressure plate 220 can be mounted on the support shaft 200 by screws. The pressure plate 220 has a circular hole (not shown) corresponding to each ball, the inner diameter of which is smaller than the diameter of the ball. The support shaft 200 also generally has a groove (not shown) at the position of each ball, with the ball partially housed within the groove and protruding from the corresponding circular hole, thus achieving positioning. Furthermore, when some balls wear out and need replacement, only the pressure plate 220 needs to be removed, facilitating maintenance of the cantilever mechanism 10.

[0038] The pusher sleeve 300 is fitted onto the support shaft 200 and can move axially along the support shaft 200. The drive assembly 400 is connected to the pusher sleeve 300 and can drive the pusher sleeve 300 to move axially along the support shaft 200. The pusher sleeve 300 has a hollow cylindrical structure, and its inner diameter is larger than the outer diameter of the support shaft 200. After the material roll 20 is delivered to the position, the drive assembly 400 first drives the pusher sleeve 300 to move outward along the support shaft 200 (towards the side away from the base 100), thereby applying a pushing force to the material roll 20 by the pusher sleeve 300. Since the end face of the pusher sleeve 300 is annular, it can apply a pushing force to the material roll 20 circumferentially, thereby making the force on the material roll 20 more even.

[0039] Furthermore, since the inner wall of the material roll 20 is in direct contact with the rolling element 210, the friction between the material roll and the support shaft 200 is relatively small. Therefore, under the pushing force of the pusher sleeve 300, the material roll 20 can move towards the end along the axial direction of the support shaft 200 until the material roll 20 slides out from the end of the support shaft 200 to complete the unloading. In other words, no manual operation is required during the unloading process of the material roll 20; the aforementioned cantilever mechanism 10 can automatically perform the relevant operations.

[0040] In this embodiment, a limiting block 500 is provided at one end of the support shaft 200 away from the base 100. The limiting block 500 can be operably switched so that the limiting block 500 protrudes or is recessed relative to the surface of the support shaft 200.

[0041] The limiting block 500 and the support shaft 200 can be connected by a lifting structure (not shown) or an elastic structure (not shown), so that the limiting block 500 can move up and down relative to the surface of the support shaft 200, thereby achieving position switching. Specifically, the limiting block 500 can be manually operated to switch positions, or it can be automatically operated by setting a micro switch or other means.

[0042] During the operation of the automated guided vehicle, the limiting block 500 can be operated to protrude from the surface of the support shaft 200. In this way, the limiting block 500 can limit the material roll 20, thereby preventing the material roll 20 from falling off the support shaft 200 during the transfer process. When unloading, the limiting block 500 is operated to make it recessed from the surface of the support shaft 200. In this way, the limiting block 500 will not prevent the material roll 20 from sliding off the end of the support shaft 200.

[0043] Please refer to the following: Figure 4 In this embodiment, a plurality of rollers 310 are installed at intervals along the circumference of the inner wall of the pusher sleeve 300. The rollers 310 abut against the surface of the support shaft 200, so that the pusher sleeve 300 can move axially along the support shaft 200. The rollers 310 and the surface of the support shaft 200 have rolling friction, which can reduce the resistance encountered by the pusher sleeve 300 when moving along the support shaft 200.

[0044] Furthermore, in this embodiment, the inner wall of the pusher sleeve 300 is provided with a plurality of supports 320 spaced circumferentially along the pusher sleeve 300. Each support 320 is provided with two rollers 310, and the two rollers 310 are set at an angle. The angle between the two rollers 310 is approximately equal to the interval angle between the two rollers 310 in the circumferential direction of the support shaft 200. In this way, the two rollers 310 can make better contact with the surface of the support shaft 200, so that the pusher sleeve 300 can move more smoothly.

[0045] Please refer to it again. Figure 2 and Figure 3 In this embodiment, the drive assembly 400 includes a drive motor 410 and a transmission chain 420. The transmission chain 420 is annular and is sleeved on the rotating end of the drive motor 410 and extends axially along the support shaft 200. Furthermore, the inner wall of the pusher sleeve 300 is connected to the transmission chain 420.

[0046] The drive motor 410 is fixedly mounted on the base 100 and drives the transmission chain 420. Specifically, the drive motor 410 can rotate forward and reverse, thereby driving the transmission chain 420 to reciprocate. As the transmission chain 420 rotates, it drives the pusher sleeve 300 to move reciprocally along the axial direction of the support shaft 200. Moreover, the transmission chain 420 has a long stroke, allowing the pusher sleeve 300 to move within a wider range, thus enabling smooth unloading of different types of material rolls 20.

[0047] Furthermore, in this embodiment, the support shaft 200 has a hollow structure, and a window (not shown) is provided at the end of the support shaft 200 away from the base 100. The transmission chain 420 passes through the window so that part of the transmission chain 420 passes through the interior of the support shaft 200.

[0048] Specifically, after passing through the window, the drive chain 420 will exit from the end of the support shaft 200 near the base 100. A gear (not shown) can be installed at the window to support the drive chain 420. Since the interior of the support shaft 200 can accommodate part of the drive chain 420, the space occupied by the drive chain 420 on the outside of the support shaft 200 can be reduced, thus making the structure of the cantilever mechanism 10 more compact.

[0049] Furthermore, in this embodiment, a clearance hole 110 is formed on the base 100, and the drive motor 410 is disposed on the side of the base 100 facing away from the base 100. The transmission chain 420 passes through the clearance hole 110. Since the drive motor 410 is relatively heavy, disposing of it and the support shaft 200 on opposite sides of the base 100 respectively allows the center of gravity of the cantilever mechanism 10 to be more centrally distributed, which helps to improve the stability of the cantilever mechanism 10.

[0050] In the aforementioned material roll transfer device and cantilever mechanism 10, when transferring the material roll 20, the material roll 20 is first placed on the support shaft 200. As the automated guided vehicle moves, the material roll 20 can be transported to the target position. After the material roll 20 is in place, the drive assembly 400 first drives the pusher sleeve 300 to move outward along the support shaft 200, thereby applying a pushing force to the material roll 20. Since the inner wall of the material roll 20 is in direct contact with the rolling element 210, the friction between the material roll 20 and the support shaft 200 is relatively small. Therefore, under the pushing force of the pusher sleeve 300, the material roll 20 can move axially towards the end of the support shaft 200 until the material roll 20 slides out from the end of the support shaft 200 to complete the unloading. It can be seen that during the unloading process of the material roll 20, the aforementioned material roll transfer device and cantilever mechanism 10 can automatically perform the relevant operations without manual operation, thus making the unloading operation of the material roll 20 more convenient.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
