[0002] The conveying device is widely used in the technical field of intelligent logistics. For example, the conveying device can automatically convey materials, and the conveying device can rotate the materials to change the conveying direction. However, the conventional conveying device usually has the defects of low steering accuracy, weak carrying capacity and impact resistance. SUMMARY

[0003] One of the technical problems solved by the present application is how to improve the carrying capacity and impact resistance while ensuring the steering accuracy.

[0004] A conveying device comprises:

[0005] a rack;

[0006] a first mounting plate arranged on the rack;

[0008] In one of the embodiments, the first conveying assembly comprises a base plate, a first support beam and a first rotating piece, the base plate is fixed on the driven gear, the number of the first support beams is two, the two first support beams are arranged on the base plate at intervals, and the two ends of the first rotating piece are rotationally connected with the two first support beams respectively and are used for carrying materials, the number of the first rotating pieces is multiple, and the multiple first rotating pieces are arranged at intervals along the conveying direction of the materials.

[0009] In one of the embodiments, the steering mechanism further comprises two stop assemblies, the two stop assemblies are arranged near the two ends of the first conveying assembly respectively, and the two stop assemblies are used for abutting against the materials along the conveying direction of the materials.

[0010] In one of the embodiments, the stop assembly comprises a cylinder, a stop piece and a slide rod, the cylinder is fixed on the first conveying assembly and is connected with the stop piece, and the slide rod is arranged on the stop piece and is slidingly connected with the first conveying assembly.

[0011] In one of the embodiments, a slide hole is formed in the first conveying assembly, and the slide rod is slidingly matched with the slide hole.

[0012] In one of the embodiments, the turning mechanism further comprises a first detecting member arranged on the first conveying assembly to detect whether there is material on the first conveying assembly.

[0013] In one of the embodiments, the driven gear has a diameter greater than twice the diameter of the driving gear.

[0014] In one of the embodiments, the turning mechanism further comprises a support member arranged on the first mounting plate and a roller rotatably connected with the support member and bearing the first conveying assembly.

[0015] In one of the embodiments, the turning mechanism further comprises a second mounting plate arranged on the frame and spaced apart from the first mounting plate, and a second conveying assembly arranged on the second mounting plate.

[0016] In one of the embodiments, the second conveying assembly comprises a second support beam and a second rotating member, the second support beam has two second support beams arranged on the second mounting plate in a spaced apart manner, and the second rotating member has two ends rotatably connected with the two second support beams and used for bearing the material, and the second rotating member has a plurality of second rotating members arranged in a spaced apart manner along the conveying direction of the material.

[0017] One of the technical effects of one of the embodiments is that, since the turning mechanism comprises the driver, the driving gear and the driven gear, i.e., the first conveying assembly is driven to rotate to achieve the turning of the material through the meshing relationship between the driving gear and the driven gear.

[0029] Referring to Figure 1 , Figure 2 and Figure 3 , an embodiment of the present application provides a conveying device 10 for conveying material 20, the conveying device 10 comprising a frame 100, a first mounting plate 200 and a turning mechanism 300, the first mounting plate 200 being arranged on the frame 100, and the turning mechanism 300 being arranged on the first mounting plate 200.

[0030] Referring to Figure 1 , Figure 2 and Figure 3In some embodiments, the rack 100 can include a frame 110, a foot 120, a fixing member 130 and a universal wheel 140. The frame 110 can be a cuboid structure, the first mounting plate 200 is arranged on the frame 110, and the foot 120 is arranged on the frame 110 and used to contact a support surface such as the ground, thereby supporting and bearing the rack 100 and the entire conveying device 10. The fixing member 130 is arranged on the frame 110 and can be fixed to the support surface such as the ground by bolts, thereby achieving a fixed connection relationship between the conveying device 10 and the support surface such as the ground, and avoiding slippage of the conveying device 10 relative to the ground. The universal wheel 140 is also arranged on the frame 110 and contacts the support surface such as the ground, so that the universal wheel 140 can roll on the ground, thereby enabling the universal wheel 140 to drive the entire conveying device 10 to move on the support surface such as the ground, thereby facilitating the conveying device 10 to be carried.

[0031] Referring to Figure 2 , Figure 3 and Figure 4 In some embodiments, the turning mechanism 300 includes a driver 310, a driving gear 320, a driven gear 330 and a first conveying assembly 340. The driver 310 is arranged on the first mounting plate 200, the driving gear 320 is connected with the driver 310, the driven gear 330 is rotationally connected with the first mounting plate 200 and engaged with the driving gear 320, and the first conveying assembly 340 is used to convey the material 20 and arranged on the driven gear 330. The driver 310 can be a servo motor or a stepper motor. When the driver 310 drives the driving gear 320 to rotate, the driving gear 320 drives the driven gear 330 to rotate, and then the first conveying assembly 340 synchronously rotates with the driven gear 330. When the first conveying assembly 340 rotates, the material 20 can be rotated by a certain angle, thereby changing the placement angle of the material 20, i.e., achieving the turning of the material 20, and finally achieving the conveying of the material 20 in different directions,

[0032] For the conventional steering mechanism 300, there are usually the following defects: first, the weight of the material 20 is uncertain, but the steering mechanism 300 cannot bear the material 20 with a large weight, that is, the carrying capacity of the conveying device 10 is limited, which leads to the conveying device 10 being difficult to adapt to various working conditions. Second, when impact occurs due to instability during movement, it will cause the entire steering mechanism 300 to malfunction or be damaged, thereby reducing the impact resistance and reliability of the conveying device 10. Third, the steering mechanism 300 has frequent start and stop actions, and it is difficult to control the acceleration of the steering mechanism 300, so that the material 20 is difficult to move accurately to the specified position, thereby affecting the steering accuracy of the steering mechanism 300. At the same time, the steering mechanism 300 can only rotate by a limited number of angles, that is, the steering mechanism 300 can only rotate the material 20 by a specific angle, and when it is necessary to rotate the material 20 to other angles outside the specific angle, the steering mechanism 300 will not be able to achieve it, which further affects the steering accuracy of the steering mechanism 300.

[0033] For the steering mechanism 300 in the above embodiments, since the steering mechanism 300 includes the driver 310, the driving gear 320, and the driven gear 330, that is, the first conveying assembly 340 is driven to rotate to achieve the steering of the material 20 through the gear engagement relationship. Therefore, the following beneficial effects will exist: first, the engagement of the driving gear 320 and the driven gear 330 will generate a large driving force, so that the first conveying assembly 340 can carry the material 20 with a large weight, thereby improving the carrying capacity of the steering mechanism 300 and the adaptability of the entire conveying device 10 to different working conditions. Second, the movement of the driving gear 320 and the driven gear 330 is stable and difficult to produce internal impact, and even if there is external impact, it is difficult to cause the driving gear 320 and the driven gear 330 to malfunction or be damaged, thereby improving the impact resistance and reliability of the steering mechanism 300 and the conveying device 10. Third, the engagement of the driving gear 320 and the driven gear 330 can well control the acceleration of the first conveying assembly 340, so that the first conveying assembly 340 and the material 20 can move to the specified position, thereby improving the steering accuracy of the steering mechanism 300. At the same time, the first conveying assembly 340 can rotate by 360°, so that the first conveying assembly 340 can rotate by any angle, thereby realizing the steering of the material 20 by any angle by the steering mechanism 300, which further affects the steering accuracy of the steering mechanism 300.

[0034] Referring to Figure 2 , Figure 3 and Figure 4In some embodiments, the first conveying assembly 340 comprises a base plate 341, two first support beams 342 and a plurality of first rotating members 343. The base plate 341 is fixed on the driven gear 330. The two first support beams 342 extend along the conveying direction of the material 20, and are spaced apart on the base plate 341 in a direction perpendicular to the conveying direction of the material 20. The first rotating members 343 extend along the direction perpendicular to the conveying direction of the material 20, and both ends of the first rotating members 343 are rotatably connected to the first support beams 342. The material 20 is carried on the first rotating members 343. When the first rotating members 343 rotate, the material 20 can move linearly relative to the first support beams 342. During the linear movement of the material 20, the first support beams 342 can limit the two sides of the material 20, thereby improving the movement accuracy of the material 20.

[0035] Referring to Figure 2 , Figure 3 and Figure 4 In some embodiments, the turning mechanism 300 further comprises two stop assemblies 350, which are arranged near the two ends of the first conveying assembly 340 respectively, and are used to abut against the material 20 along the conveying direction of the material 20. During the turning of the material 20 by the first conveying assembly 340 following the rotation of the driven gear 330, the two stop assemblies 350 can abut against the two ends of the material 20 along the conveying direction of the material 20 respectively, thereby preventing the material 20 from slipping along the conveying direction, and finally improving the turning accuracy of the turning mechanism 300 to the material 20.

[0036] Referring to Figure 2 , Figure 3 and Figure 4In some embodiments, the stop component 350 comprises a cylinder 351, a stop piece 352 and a slide rod 353. The cylinder barrel of the cylinder 351 can be fixed on the base plate 341, and the piston rod of the cylinder 351 is connected with the stop piece 352, so that the piston rod drives the stop piece 352 to move close to or away from the base plate 341 when the piston rod is retracted and extended. The end of the slide rod 353 is fixed on the stop piece 352, and a slide hole 3411 can be formed on the base plate 341, and the slide rod 353 is in sliding fit with the slide hole 3411. Through the cooperation of the slide rod 353 and the slide hole 3411, the smoothness and accuracy of the movement of the slide rod 353 and the stop piece 352 can be improved. When it is needed to input or output the material 20 relative to the first conveying component 340, the cylinder 351 can be driven to drive the stop piece 352 to move close to the base plate 341 by a set distance, so that the interference of the stop piece 352 to the material 20 can be eliminated, and the material 20 can be smoothly input to or output from the first conveying component 340. When it is needed to prevent the material 20 from slipping relative to the first conveying component 340, the cylinder 351 can be driven to drive the stop piece 352 to move away from the base plate 341 by a set distance, so that the stop piece 352 abuts against the end of the material 20, and the positioning of the stop piece 352 to the material 20 is realized. The number of the slide rods 353 is two, and the two slide rods 353 are respectively arranged close to the two ends of the stop piece 352, and the number of the slide hole 3411 and the slide rod 353 is equal to form a one-to-one correspondence relationship.

[0037] Referring to Figure 2 , Figure 3 and Figure 4 In some embodiments, the turning mechanism 300 further comprises a first detection piece 360 arranged on the first conveying component 340 to detect whether the material 20 exists on the first conveying component 340. For example, the first detection piece 360 can comprise a transmitting part and a receiving part, and the transmitting part and the receiving part are respectively fixed on the two first support beams 342. When the material 20 exists on the first conveying component 340, the light generated by the transmitting part is blocked by the material 20, so that the receiving part cannot receive the light generated by the transmitting part. At this time, the first detection piece 360 will feed back the signal that the material 20 exists on the first conveying component 340. When the material 20 does not exist on the first conveying component 340, the light generated by the transmitting part is not blocked by the material 20, so that the receiving part can receive the light generated by the transmitting part. At this time, the first detection piece 360 will feed back the signal that the material 20 does not exist on the first conveying component 340. In other embodiments, the first detection piece 360 can also detect whether the material 20 exists on the first conveying component 340 through other ways.

[0038] In some embodiments, the diameter of the driven gear 330 is greater than the diameter of the driving gear 320, for example, the diameter of the driven gear 330 is greater than twice the diameter of the driving gear 320, so that the driven gear 330 has a relatively small rotation speed and a relatively large torque, so as to improve the steering accuracy of the steering mechanism 300 and improve the carrying capacity of the steering mechanism 300.

[0039] Referring to Figure 3 , Figure 4 and Figure 5 In some embodiments, the steering mechanism 300 further comprises a support 371 and a roller 372. The support 371 is arranged on the first mounting plate 200, and the roller 372 is rotationally connected with the support 371, and the roller 372 is in contact with the base plate 341 to bear the base plate 341. During the rotation of the first conveying assembly 340 relative to the first mounting plate 200, the roller 372 of the first conveying assembly 340 bears the base plate 341, thereby improving the stability of the movement of the first conveying assembly 340, thereby improving the steering accuracy of the steering mechanism 300. The roller 372 and the base plate 341 generate rolling friction, which can reduce the frictional resistance between the base plate 341 and the roller 372, and further improve the smoothness of the rotation of the first conveying assembly 340.

[0040] Referring to Figure 1 and Figure 2 In some embodiments, the conveying device 10 further comprises a second mounting plate 400 and a second conveying assembly 500. The second mounting plate 400 is arranged on the rack 100 and is arranged in a spaced manner with the first mounting plate 200, that is, the second mounting plate 400 is arranged in a spaced manner with the first mounting plate 200 along the height direction of the rack 100. The second conveying assembly 500 is arranged on the second mounting plate 400, and the second conveying assembly 500 can only convey the material 20 in a specific direction, that is, the second conveying assembly 500 cannot steer the material 20. The number of second mounting plates 400 and second conveying assemblies 500 is equal to form a one-to-one correspondence, that is, one second conveying assembly 500 is arranged on one second mounting plate 400. The first mounting plate 200 can be located above or below the second mounting plate 400, so that the first conveying assembly 340 can be located above or below the second conveying assembly 500. The number of second conveying assemblies 500 can be greater than or equal to the number of first conveying assemblies 340.

[0041] Referring to Figure 1 and Figure 2In some embodiments, the second conveying assembly 500 can have substantially the same structure as the first conveying assembly 340, i.e. the second conveying assembly 500 comprises a second support beam 510 and a second rotating member 520. The second support beam 510 can be two in number and extend along the conveying direction of the material 20, such that the two second support beams 510 are spaced apart along a direction perpendicular to the conveying direction of the material 20 on the second mounting plate 400. The second rotating member 520 can extend along a direction perpendicular to the conveying direction of the material 20, such that both ends of the second rotating member 520 can be rotatably connected to the second support beam 510, and the material 20 is carried on the second rotating member 520. The second rotating member 520 can be multiple in number and spaced apart along the conveying direction of the material 20. When the second rotating member 520 rotates, the material 20 can be caused to move linearly relative to the second support beam 510. During the linear movement of the material 20, the second support beam 510 can limit the two sides of the material 20, thereby improving the movement accuracy of the material 20.

[0042] Referring to Figure 1 and Figure 2 In some embodiments, the second conveying assembly 500 can further comprise a second detection member 530, which can have substantially the same working principle and structure as the first detection member 360, and the second detection member 530 can be arranged on the second support beam 510 to detect whether the material 20 exists on the second conveying assembly 500.

[0043] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0044] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
