[0006] Summary of the Invention

[0007] In view of this, the embodiments of the present disclosure hope to provide a conveying device and a production line that facilitate the disassembly of the conveyor belt.

[0008] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present disclosure is implemented as follows:

[0009] The present disclosure provides a conveying device, comprising:

[0010] Bracket;

[0011] conveyor;

[0012] A first shaft is arranged in the annular space of the conveyor belt;

[0013] A second shaft is provided in the annular space of the conveyor belt, wherein the first shaft and the second shaft are respectively located at two ends of the conveyor belt along the conveying direction;

[0014] A support seat is provided on the bracket, wherein the axial ends of the first shaft are respectively provided with a support seat, and the shaft ends of the first shaft are detachably connected to the support seat;

[0015] A bearing seat is arranged on the bracket, and one bearing seat is respectively provided at the axial ends of the second shaft, and the axial ends of the second shaft are detachably connected to the bearing seat.

[0016] The conveying equipment provided by the embodiment of the present disclosure can, when the conveyor belt needs to be maintained or replaced, remove the first shaft from the support seat, remove the second shaft from the bearing seat, and then pull the conveyor belt out from the first shaft and the second shaft to complete the disassembly of the conveyor belt. When the conveyor belt needs to be assembled to the bracket, the first shaft and the second shaft can be inserted into the annular space, and the first shaft can be installed on the support seat, and the second shaft can be installed on the bearing seat to complete the installation of the conveyor belt. In this way, there is no need to disassemble the support seat and the bearing seat from the bracket. The conveyor belt can be conveniently disassembled by disassembling the first shaft and the second shaft, thereby reducing the difficulty of maintenance and replacement of the conveyor belt.

[0017] In some embodiments, the support seat includes two detachably connected seat bodies, the two seat bodies define a mounting hole, and the shaft end of the first shaft is accommodated in the mounting hole.

[0018] In this embodiment, the wall of the mounting hole can restrict the end of the first shaft from separating from the support seat, thereby detachably connecting the end of the first shaft to the support seat. The two seats are of a split structure. If the first shaft needs to be removed, one seat can be removed from the other, and the first shaft can be removed, which is simple and convenient.

[0019] In some embodiments, the two bases are stacked in an up-down direction.

[0020] In this embodiment, during the disassembly process, the operator does not need to hold the first shaft to assist in disassembling the seat body, thereby reducing the difficulty of the operation.

[0021] In some embodiments, the base body is formed with an open slot, and the open slots of two base bodies are spliced ​​relative to each other to form the mounting hole.

[0022] In this embodiment, the shaft end of the first shaft is located in the open grooves of the two base bodies, and the two base bodies jointly clamp the shaft end of the first shaft. When the first shaft needs to be disassembled, one of the base bodies can be disassembled from the other base body, and the first shaft can be taken out from the opening of the open groove.

[0023] In some embodiments, a rotating bearing is provided at the shaft end of the first shaft, the support seat forms a limiting flange, the limiting flange is provided in the mounting hole, and the rotating bearing is accommodated in the mounting hole and abuts against the limiting flange.

[0024] In this embodiment, the limiting flange limits the axial movement of the first shaft, thereby reducing the axial movement of the first shaft.

[0025] In some embodiments, the supporting seat is formed with a placement groove for accommodating the shaft end of the second shaft, and the supporting seat is formed with an inlet and outlet connected to the placement groove on one side along the conveying direction, and the shaft end of the second shaft enters and exits the placement groove through the inlet and outlet.

[0026] In this embodiment, the walls of the placement slot restrict the second shaft's end from disengaging, thereby providing a removable connection between the second shaft end and the support base. To disassemble the second shaft, the second shaft end can be removed from the placement slot through the access port. To assemble the second shaft end to the support base, the second shaft end can be placed back into the placement slot through the access port, providing a simple and convenient operation.

[0027] In some embodiments, the conveying device includes a tensioning mechanism disposed on the bracket, the tensioning mechanism is located on a side of the bearing seat where the inlet and outlet are formed, and the tensioning mechanism can abut against or release the second shaft.

[0028] In this embodiment, on the one hand, the force of the tensioning mechanism prevents the second shaft from slipping out of the inlet and outlet, thereby restricting the second shaft's movement. On the other hand, the tensioning mechanism forces the end of the second shaft to abut against the wall of the placement slot, allowing the second shaft to tension the conveyor belt. For example, if the conveyor belt needs to be removed, the tensioning mechanism can be used to release the second shaft, allowing the second shaft to slip out of the placement slot through the inlet and outlet, leaving the conveyor belt in a relaxed state, facilitating its removal.

[0029] In some embodiments, the tensioning mechanism includes a fixing seat and an adjusting screw, the fixing seat is connected to the bracket, a threaded hole is formed in the fixing seat, the adjusting screw is threadedly engaged with the threaded hole, and the adjusting screw abuts or releases the second shaft.

[0030] In this embodiment, the adjusting screw can be rotated forward to move the adjusting screw away from the second shaft, thereby releasing the second shaft and allowing the second shaft to be disengaged from the inlet and outlet; the adjusting screw can be rotated backward to move the adjusting screw closer to and abut against the second shaft, thereby preventing the second shaft from being disengaged from the inlet and outlet. The tensioning mechanism is simple and easy to operate.

[0031] In some embodiments, the adjusting screw extends along the conveying direction, and the adjusting screw rotates relative to the fixing base to move closer to or away from the second axis.

[0032] In this embodiment, the adjusting screw can be rotated forward to move the adjusting screw away from the second shaft, thereby releasing the second shaft and allowing the second shaft to be disengaged from the inlet and outlet; the adjusting screw can be rotated backward to move the adjusting screw closer to and abut against the second shaft, thereby preventing the second shaft from being disengaged from the inlet and outlet. The tensioning mechanism is simple and easy to operate.

[0033] In some embodiments, the second shaft includes a shaft core and a roller, the roller is rotatably sleeved outside the shaft core, and the adjusting screw is pressed against the shaft end of the shaft core to limit the shaft core.

[0034] In this embodiment, during the rotation of the conveyor belt, the shaft core remains stationary to tension the conveyor belt, and the rollers rotate around the shaft core to reduce the friction between the conveyor belt and the rollers.

[0035] In some embodiments, the conveying device includes a power source, and the power source drives the first shaft to rotate.

[0036] In this embodiment, the power source drives the first shaft to rotate, and the rotation of the first shaft drives the conveyor belt and the second shaft to rotate.

[0037] In some embodiments, the power source includes an electric motor.

[0038] In this embodiment, the motor drives the first shaft to rotate.

[0039] In some embodiments, the motor shaft of the motor and the first shaft are detachably connected via a coupling.

[0040] In this embodiment, the first shaft can be driven to rotate synchronously by the motor shaft. It is understandable that when the first shaft is disassembled, the coupling and the first shaft can be loosened so that the first shaft can be disassembled from the support seat.

[0041] In some embodiments, the conveying device includes a protrusion and a groove, one of the protrusion and the groove is arranged on the inner surface of the conveyor belt, and the other of the protrusion and the groove is arranged on the outer circumferential surface of both the first shaft and the second shaft, and the protrusion can be slidably accommodated in the groove.

[0042] In this embodiment, during the rotation of the conveyor belt, the protrusion slides in the groove, and the two axial groove walls of the groove can limit the protrusion from moving in the axial direction. Therefore, the conveyor belt cannot be offset in the axial direction, solving the problem of the conveyor belt running off course during rotation.

[0043] In some embodiments, the conveying device includes a horizontally placed support plate, the support plate is inserted into the annular space of the conveyor belt, and the support plate is detachably connected to the bracket.

[0044] In this embodiment, the support plate supports the conveyor belt. The support plate is detachably connected to the bracket. When the conveyor belt needs to be disassembled, the support plate can be first removed and removed from the annular space. The first and second shafts are then removed, and the conveyor belt is removed from the first and second shafts. This prevents the support plate from interfering with the quick disassembly and assembly of the conveyor belt, facilitating maintenance and replacement.

[0045] In some embodiments, there are multiple support plates, and the multiple support plates are arranged at intervals along the conveying direction.

[0046] In this embodiment, multiple support plates can provide reliable support for the conveyor belt, and the size of a single support plate can be small to facilitate the support plate to be pulled out from the annular space, thereby reducing the difficulty of disassembling and assembling the support plate.

[0061] The following embodiments of the technical solution of the present disclosure are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present disclosure and are therefore only examples and are not intended to limit the scope of protection of the present disclosure.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this disclosure.

[0063] In the description of the embodiments of the present disclosure, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.

[0064] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0065] It should be noted that, in FIG. 1 of the present disclosure, the direction indicated by the arrow X1 is upward, the direction indicated by the arrow X2 is downward, and Y refers to the conveying direction.

[0066] Hereinafter, the present disclosure will be described in detail.

[0067] Referring to Figures 1 to 6, an embodiment of the present disclosure provides a conveying device, which includes a bracket 1, a conveyor belt 2, a first shaft 3, a second shaft 4, a supporting seat 5 and a bearing seat 6.

[0068] Please refer to FIG. 4 . The conveyor belt 2 is an annular structure, and the inner space enclosed by the conveyor belt 2 is an annular space 2 a.

[0069] A first shaft 3 is disposed within the annular space 2a of the conveyor belt 2. A second shaft 4 is disposed within the annular space 2a of the conveyor belt 2. The first shaft 3 and the second shaft 4 are located at opposite ends of the conveyor belt 2 along the conveying direction. The first shaft 3 and the second shaft 4 drive the conveyor belt 2 to rotate, thereby moving objects on the conveyor belt 2 from one station to another along the conveying direction.

[0070] A support seat 5 is provided on the bracket 1, with a support seat 5 provided at each axial end of the first shaft 3, and the shaft end of the first shaft 3 is detachably connected to the support seat 5. A bearing seat 6 is provided on the bracket 1, with a bearing seat 6 provided at each axial end of the second shaft 4, and the shaft end of the second shaft 4 is detachably connected to the bearing seat 6.

[0071] In the conveying equipment provided by the embodiment of the present disclosure, when the conveyor belt 2 needs to be maintained or replaced, the first shaft 3 can be disassembled from the support seat 5, and the second shaft 4 can be disassembled from the bearing seat 6, and then the conveyor belt 2 can be pulled out from the first shaft 3 and the second shaft 4 to complete the disassembly of the conveyor belt 2. When the conveyor belt 2 needs to be assembled to the bracket 1, the first shaft 3 and the second shaft 4 can be inserted into the annular space 2a, and the first shaft 3 can be installed on the support seat 5, and the second shaft 4 can be installed on the bearing seat 6 to complete the installation of the conveyor belt 2. In this way, there is no need to disassemble the support seat 5 and the bearing seat 6 from the bracket 1. The conveyor belt 2 can be conveniently disassembled by disassembling the first shaft 3 and the second shaft 4, thereby reducing the difficulty of maintenance and replacement of the conveyor belt 2.

[0072] The shape of the annular space 2a defined by the conveyor belt 2 is not limited. For example, please refer to FIG. 4 . Taking the plane perpendicular to the rotation axis of the first shaft 3 as the projection plane, the projection shape of the annular space 2a defined by the conveyor belt 2 is an oval shape.

[0073] In one embodiment, referring to Figures 1 and 2 , the support base 5 includes two detachably connected base bodies 51. The two base bodies 51 define a mounting hole 5a, within which the end of the first shaft 3 is received. The wall of the mounting hole 5a prevents the end of the first shaft 3 from disengaging from the support base 5, thereby detachably connecting the end of the first shaft 3 to the support base 5. The two base bodies 51 are split. To remove the first shaft 3, one base body 51 can be detached from the other, allowing for easy and convenient removal.

[0074] For example, in one embodiment, referring to Figures 1 and 2 , the base body 51 is formed with an open slot 51a. The open slots 51a of two base bodies 51 are joined to form the mounting hole 5a. In other words, the end of the first shaft 3 is located within the open slots 51a of both base bodies 51, and the two base bodies 51 jointly clamp the end of the first shaft 3. To remove the first shaft 3, one base body 51 can be removed from the other base body 51, and the first shaft 3 can be removed through the opening of the open slot 51a.

[0075] In one embodiment, referring to Figures 1 and 2 , two base bodies 51 can be stacked vertically. For example, the opening of the opening slot 51a of one base body 51 faces upward, while the opening of the opening slot 51a of the other base body 51 faces downward. After the upper base body 51 is removed, the end of the first shaft 3 can be positioned within the opening slot 51a of the lower base body 51. This eliminates the need for the operator to manually support the first shaft 3 during the removal process, reducing the difficulty of the operation.

[0076] In one embodiment, referring to Figures 1 and 3, the support seat 6 is formed with a placement groove 6a for accommodating the shaft end of the second shaft 4. An inlet and outlet connected to the placement groove 6a are formed on one side of the support seat 6 along the conveying direction, and the shaft end of the second shaft 4 enters and exits the placement groove 6a through the inlet and outlet. The groove wall surface of the placement groove 6a restricts the shaft end of the second shaft 4 from being separated from the placement groove 6a, thereby detachably connecting the shaft end of the second shaft 4 to the support seat 6. When the second shaft 4 needs to be disassembled, the shaft end of the second shaft 4 can be taken out of the placement groove 6a through the inlet and outlet. When the shaft end of the second shaft 4 needs to be assembled to the support seat 6, the shaft end of the second shaft 4 is placed into the placement groove 6a through the inlet and outlet, which is simple and convenient to operate.

[0077] In one embodiment, referring to Figures 1 and 3 , the conveying apparatus includes a tensioning mechanism 7 disposed on the support 1. The tensioning mechanism 7 is located on the side of the support base 6 where the inlet and outlet are formed. The tensioning mechanism 7 abuts or releases the second shaft 4. Specifically, the tensioning mechanism 7 is located on the side of the support base 6 near the inlet and outlet along the conveying direction. The tensioning mechanism 7 abuts the second shaft 4, applying a force away from the inlet and outlet, thereby locking the second shaft 4. The tensioning mechanism 7 then moves away from the second shaft 4 to release the second shaft 4. On the one hand, the force exerted by the tensioning mechanism 7 prevents the second shaft 4 from slipping out of the inlet and outlet, restricting its movement. On the other hand, the tensioning mechanism 7 forces the end of the second shaft 4 into contact with the wall of the placement slot 6a, allowing the second shaft 4 to tension the conveyor belt 2. For example, if the conveyor belt 2 needs to be removed, the tensioning mechanism 7 can be used to release the second shaft 4. This allows the second shaft 4 to slip out of the placement slot 6a through the inlet and outlet, leaving the conveyor belt 2 in a relaxed state, facilitating its removal.

[0078] In one embodiment, as shown in Figure 3 , the tensioning mechanism 7 includes a fixed base 71 and an adjusting screw 72. The fixed base 71 is connected to the bracket 1 and has a threaded hole formed therein. The adjusting screw 72 engages with or releases the second shaft 4. Specifically, the adjusting screw 72 extends along the conveying direction and rotates relative to the fixed base 71 to move closer to or further away from the second shaft 4. The adjusting screw 72 can be rotated forward to move away from the second shaft 4, thereby releasing the second shaft 4 and allowing it to exit the port. The adjusting screw 72 can be rotated backward to move closer to and abut the second shaft 4, thereby preventing it from exiting the port. The tensioning mechanism 7 is simple and easy to operate.

[0079] In some embodiments, there may be two tensioning mechanisms 7 , and the two tensioning mechanisms 7 may respectively abut or release the axial ends of the second shaft 4 .

[0080] In one embodiment, the second shaft 4 includes a core and a roller, with the roller rotatably sleeved around the core. An adjusting screw 72 can abut against the end of the core to constrain the core, while the roller can rotate about the core. Thus, during the rotation of the conveyor belt 2, the core remains stationary to tension the conveyor belt 2, while the roller rotates about the core to minimize friction between the conveyor belt 2 and the roller.

[0081] In one embodiment, referring to Figures 1 and 2 , a rotary bearing 9 is provided at the end of the first shaft 3. The support base 5 forms a limiting flange 511, which is disposed within the mounting hole 5a. The rotary bearing 9 is received within the mounting hole 5a and abuts against the limiting flange 511. The limiting flange 511 limits the axial movement of the first shaft 3, thereby reducing axial play of the first shaft 3.

[0082] In one embodiment, referring to Figures 1 to 3 , the conveying device includes a power source 10 , which drives the first shaft 3 to rotate. The rotation of the first shaft 3 drives the conveyor belt 2 and the second shaft 4 to rotate.

[0083] The power source 10 includes, but is not limited to, a motor. For example, a coupling can be used to detachably connect the motor shaft and the first shaft 3. In this manner, the motor shaft can drive the first shaft 3 to rotate synchronously. It will be appreciated that when removing the first shaft 3, the coupling and the first shaft 3 can be loosened to facilitate removal of the first shaft 3 from the support base 5.

[0084] In one embodiment, referring to Figures 4 and 6 , the conveying device includes a protrusion 100 and a groove 200. One of the protrusion 100 and the groove 200 is disposed on the inner surface of the conveyor belt 2, and the other of the protrusion 100 and the groove 200 is disposed on the outer circumference of both the first shaft 3 and the second shaft 4. The protrusion 100 is slidably received in the groove 200. For example, in one embodiment, referring to Figures 4 and 6 , the protrusion 100 is disposed on the inner surface of the conveyor belt 2, and the groove 200 is disposed on the outer circumference of both the first shaft 3 and the second shaft 4. The protrusion 100 can surround the inner surface of the conveyor belt 2, the groove 200 of the first shaft 3 can surround the outer circumference of the first shaft 3, and the groove 200 of the second shaft 4 can surround the outer circumference of the second shaft 4. In another embodiment, the groove 200 is provided on the inner surface of the conveyor belt 2, and the protrusion 100 is provided on the outer circumference of both the first shaft 3 and the second shaft 4. The groove 200 can surround the inner surface of the conveyor belt 2, the protrusion 100 of the first shaft 3 can surround the outer circumference of the first shaft 3, and the protrusion 100 of the second shaft 4 can surround the outer circumference of the second shaft 4. During the rotation of the conveyor belt 2, the protrusion 100 slides within the groove 200. The two axial groove walls of the groove 200 can restrict the protrusion 100 from axial movement. Therefore, the conveyor belt 2 cannot deviate in the axial direction, solving the problem of the conveyor belt 2 running off during rotation.

[0085] In one embodiment, referring to Figures 1, 4, and 5, the conveying apparatus includes a horizontally positioned support plate 8, which extends through the annular space 2a of the conveyor belt 2 and is detachably connected to the bracket 1. The support plate 8 supports the conveyor belt 2. The detachable connection between the support plate 8 and the bracket 1 facilitates disassembly of the conveyor belt 2 by first removing the support plate 8 from the annular space 2a, then removing the first and second shafts 3, 4, and removing the conveyor belt 2 from the first and second shafts 3, 4. This prevents interference between the support plate 8 and the conveyor belt 2, allowing for quick assembly and disassembly, facilitating maintenance and replacement.

[0086] In one embodiment, referring to Figures 1, 4, and 5, a plurality of support plates 8 are provided, each spaced apart along the conveying direction. This design allows the plurality of support plates 8 to provide reliable support for the conveyor belt 2, and allows a single support plate 8 to be relatively small, making it easier to remove the support plate 8 from the annular space 2a and thereby reducing the difficulty of assembly and disassembly.

[0087] In one embodiment, referring to Figures 1, 4, and 5, the conveying device includes a protrusion 100 and a groove 200, one of which is disposed on the inner surface of the conveyor belt 2, and the other of which is disposed on the upper surface of the support plate 8. The protrusion 100 is slidably received in the groove 200. For example, in one embodiment, referring to Figures 1, 4, and 5, the protrusion 100 is disposed on the inner surface of the conveyor belt 2, and the groove 200 is disposed on the upper surface of the support plate 8. The protrusion 100 may surround the inner surface of the conveyor belt 2, and the groove 200 may pass through both ends of the support plate 8 along the conveying direction. In another embodiment, the groove 200 is disposed on the inner surface of the conveyor belt 2, and the protrusion 100 is disposed on the upper surface of the support plate 8. The groove 200 may surround the inner surface of the conveyor belt 2, and the protrusion 100 may extend to both ends of the support plate 8 along the conveying direction. During the rotation of the conveyor belt 2, the protrusion 100 slides in the groove 200. The two axial groove walls of the groove 200 can limit the protrusion 100 from moving in the axial direction. Therefore, the conveyor belt 2 cannot be offset in the axial direction, solving the problem of the conveyor belt 2 running off during rotation.

[0088] It is understood that in some embodiments, the conveyor belt 2 is provided with a groove 200, and the first shaft 3, the second shaft 4, and the support plate 8 are all provided with a protrusion 100. In other embodiments, referring to Figures 1, 4, 5, and 6, the conveyor belt 2 is provided with a protrusion 100, and the first shaft 3, the second shaft 4, and the support plate 8 are all provided with a groove 200.

[0089] In one embodiment, referring to Figures 1 and 5 , the conveying apparatus includes a fastener. A portion of support plate 8 protrudes axially from conveyor belt 2 along first axis 3 to form a connecting portion 81. The fastener is detachably disposed vertically through connecting portion 81 and bracket 1. Specifically, the horizontal projection of connecting portion 81 is located to one side of the horizontal projection of conveyor belt 2 in the axial direction. If support plate 8 needs to be removed, the fastener can be removed vertically, avoiding interference with other structures and facilitating operation.

[0090] Types of fasteners include, but are not limited to, screws or bolts.

[0091] For example, in one embodiment, referring to FIG. 5 , the connecting portion 81 is formed with a mounting groove 81 a , which passes through the outer periphery of the connecting portion 81 , and the fastener is inserted into the mounting groove 81 a .

[0092] The present disclosure also provides a production line for producing batteries, wherein the production line includes the conveying device according to any one of the embodiments of the present disclosure.

[0093] The conveyor belt 2 can be used to place batteries or cells. The first shaft 3 and the second shaft 4 drive the conveyor belt 2 to rotate, so that the batteries or cells on the conveyor belt 2 move from one station to another along the conveying direction.
