[0027] The present invention will be described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. Those skilled in the art can fully understand the present invention without the description of these details. In order to avoid obscuring the essence of the present invention, well-known methods, processes, and procedures are not described in detail. Additionally, the drawings are not necessarily drawn to scale.

[0028] An embodiment of the present invention provides an alignment device, as Figure 1 shown, including a carrier 1. A bearing surface 11 for placing an object is provided on the carrier 1. At least one set of transverse first alignment structures 2 and at least one set of longitudinal second alignment structures 3 are fixedly arranged on the carrier 1. The first alignment structure 2 and the second alignment structure 3 are connected to a control device. The control device controls the first alignment structure 2 to perform transverse alignment and controls the second alignment structure 3 to perform longitudinal alignment so that the object can fall into a predetermined position A.

[0029] In the alignment device provided by the embodiment of the present invention, a carrier is included. An area for placing an object is provided on the carrier. At least one set of transverse first alignment structures and at least one set of longitudinal second alignment structures are fixedly arranged on the carrier. The first alignment structure and the second alignment structure are connected to a control device. The control device controls the first alignment structure to perform transverse alignment and controls the second alignment structure to perform longitudinal alignment so that the object can fall into a designated area. From this analysis, taking the example of an unmanned aerial vehicle (UAV) dropping goods, the UAV drops the goods into the area on the carrier for placing goods. The control device controls the first alignment structure to perform transverse alignment (X-direction alignment) on the goods on the carrier and controls the second alignment structure to perform longitudinal alignment (Y-direction alignment) on the goods so that the goods can fall into the designated position on the carrier, avoiding the situation that the goods deviate from the designated position, and further ensuring that the next process can be carried out automatically and improving the efficiency of automated operations.

[0030] Specifically, as Figure 2As shown, the control device includes a plurality of transmission belts, a plurality of drive wheels, and a motor 45. The plurality of transmission belts are vertically arranged at intervals, and the shapes of the plurality of transmission belts are closed structures arranged circumferentially around the edge of the bearing surface, and the planes where the closed structures are located are parallel to each other.

[0031] In the following embodiments, the present invention will be described in detail taking the bearing surface as a rectangle as an example. Of course, the following embodiments are only examples and should not constitute any limitation to the functions and usage scopes of the embodiments of the present invention.

[0032] The plurality of transmission belts include a first transmission belt 41a and a second transmission belt 41b, and the first transmission belt 41a is arranged above the second transmission belt 41b.

[0033] The plurality of drive wheels are vertically arranged at one corner of the bearing table 1, the axes of the plurality of drive wheels are connected to the output shaft of the motor 45, and the motor 45 is used to drive the drive wheels to rotate in the same direction and at the same speed.

[0034] The plurality of drive wheels include a first drive wheel 42a and a second drive wheel 42b. The first drive wheel 42a is used to drive the first transmission belt 41a, and the second drive wheel 42b is used to drive the second transmission belt 41b. Specifically, as Figure 3 shown, the inner side of the first transmission belt 41a meshes with the outer side wheel of the first drive wheel 42a, and the outer side of the second transmission belt 41b meshes with the inner side wheel of the second drive wheel 44.

[0035] A plurality of auxiliary wheels are also arranged on both sides of the second drive wheel 44 for tensioning and limiting the second transmission belt 41b. Specifically, a first auxiliary wheel 43a and a second auxiliary wheel 43b are arranged on the bearing table 1. The first auxiliary wheel 43a is adjacent to the second drive wheel 42b in the X direction, and the second auxiliary wheel 43b is adjacent to the second drive wheel 42b in the Y direction. The first auxiliary wheel 43a, the second auxiliary wheel 43b, and the second drive wheel 42b are located in the same plane. The inner side of the second transmission belt 41b meshes with the outer side wheels of the first auxiliary wheel 43a and the second auxiliary wheel 43b respectively. The first auxiliary wheel 43a and the second auxiliary wheel 43b are used to tension and limit the second transmission belt 41b in the X direction and the Y direction, so that the second transmission belt 41b can be tightly meshed with the second drive wheel 42b.

[0036] Continue to refer to Figure 2, a plurality of sets of synchronous wheels are further provided on the carrier 1. The plurality of sets of synchronous wheels are arranged at the remaining corners of the carrier 1. Each set of synchronous wheels includes a first synchronous wheel 46a and a second synchronous wheel 46b which are arranged at intervals up and down. The first synchronous wheel 46a meshes with the first transmission belt 41a, and the second synchronous wheel 46b meshes with the second transmission belt 41b. The first synchronous wheel 46a and the second synchronous wheel 46b are respectively used to prevent the first transmission belt 41a and the second transmission belt 41b from loosening during rotation. The first synchronous wheel 46a and the second synchronous wheel 46b are respectively used to limit the first transmission belt 41a and the second transmission belt 41b.

[0037] Drive belt guards 47 are further respectively provided on the first drive belt 41a and the second drive belt 41b. The drive belt guards 47 are strip-shaped structures extending along the edge of the carrier 1. The cross-section of the drive belt guards 47 is "U" shaped. The portions of the first drive belt 41a and the second drive belt 41b located at the edge of the carrier 1 are located in the groove structures of the drive belt guards 47. The drive belt guards 47 can improve the load-bearing capacity of the first drive belt 41a and the second drive belt 41b, and are also used to limit the first drive belt 41a and the second drive belt 41b.

[0038] In addition, the first alignment structure 2 includes a first alignment rod 21 and a second alignment rod 22. The first alignment rod 21 and the second alignment rod 22 are respectively arranged in parallel on the left and right sides of the area A, and are symmetrically arranged corresponding to the center position of the area A. The two ends of the first alignment rod 21 and the second alignment rod 22 are respectively connected to the first drive belt 41a and the second drive belt 41b through connecting members. Specifically, as Figure 2 shown, the first end of the first alignment rod 21 is connected to the first drive belt 41a, and the second end is connected to the second drive belt 41b; the first end of the second alignment rod 22 is connected to the second drive belt 41b, and the second end is connected to the first drive belt 41a. When the first drive belt 41a and the second drive belt 41b rotate, they can drive the first alignment rod 21 and the second alignment rod 22 to move.

[0039] The second alignment structure 3 includes a third alignment rod 31 and a fourth alignment rod 32. The third alignment rod 31 and the fourth alignment rod 32 are respectively arranged in parallel on the upper and lower sides of the area A, and are symmetrically arranged corresponding to the center position of the area A. The two ends of the third alignment rod 31 and the fourth alignment rod 32 are respectively connected to the first drive belt 41a and the second drive belt 41b through connecting members. Specifically, as Figure 2 shown, the first end of the third alignment rod 31 is connected to the first drive belt 41a, and the second end is connected to the second drive belt 41b; the first end of the fourth alignment rod 32 is connected to the second drive belt 41b, and the second end is connected to the first drive belt 41a. When the first drive belt 41a and the second drive belt 41b rotate, they can drive the third alignment rod 31 and the fourth alignment rod 32 to move.

[0040] Of course, the connection relationship between the alignment rod and the transmission belt of the present application is not limited to the above embodiments. In the alignment device of other embodiments, the first ends of the first alignment rod 21 and the third alignment rod 31 are connected to the second transmission belt 41b, and the second ends of the first alignment rod 21 and the third alignment rod 31 are connected to the first transmission belt 41a. The first ends of the second alignment rod 22 and the fourth alignment rod 32 are connected to the first transmission belt 41a, and the second ends of the second alignment rod 22 and the fourth alignment rod 32 are connected to the second transmission belt 41b.

[0041] During actual operation, since the meshing positions of the first transmission belt 41a and the second transmission belt 41b with the first driving wheel 42a and the second driving wheel 42b are different, when the motor drives the first driving wheel 42a and the second driving wheel 42b to rotate, the rotation directions of the first transmission belt 41a and the second transmission belt 41b are just opposite. That is, when the first transmission belt 41a rotates clockwise, the second transmission belt 41b rotates counterclockwise; when the first transmission belt 41a rotates counterclockwise, the second transmission belt 41b rotates clockwise. Thus, both ends of each alignment rod can move in the same direction.

[0042] For two alignment rods moving along the same straight line, since the transmission belts on the same side they are connected to are different, the moving directions of the two alignment rods are just opposite during the rotation of the transmission belt. Taking the first alignment rod 21 and the second alignment rod 22 as an example, the first end of the first alignment rod 21 is connected to the first transmission belt 41a, and the first end of the second alignment rod 22 is connected to the second transmission belt 41b. Therefore, during the rotation of the transmission belt, the first alignment rod 21 and the second alignment rod 22 will move away from or towards each other along the transverse (X direction). Similarly, the third alignment rod 31 and the fourth alignment rod 32 can move away from or towards each other along the longitudinal (Y direction).

[0043] In addition, in order to ensure that the alignment rods moving along different straight lines can move freely within the space enclosed by the transmission belts, the alignment rods moving along different straight lines are arranged on different planes, that is, the first alignment rod 21 and the second alignment rod 22 are arranged on the first plane, and the third alignment rod 31 and the fourth alignment rod 32 are arranged on the second plane parallel to the first plane.

[0044] In an alternative embodiment, both ends of the first to fourth alignment rods are respectively connected to the first transmission belt 41a and the second transmission belt 41b through the first connector 48a and the second connector 48b. Both the first connector 48a and the second connector 48b include a first part for connecting to the transmission belt and a second part for connecting to the alignment rod. The first parts of the first connector 48a and the second connector 48b are fixedly connected to the transmission belt, and the second parts are clamped to the alignment rod, improving the connection stability between the alignment rod and the transmission belt.

[0045] In addition, since the first drive belt 41a and the second drive belt 41b are arranged at intervals in the vertical direction, the lengths of the first parts of the first connecting member 48a and the second connecting member 48b in this embodiment are different. Taking the case where the first drive belt 41a is located above the second drive belt 41b as an example, the length of the first part of the first connecting member 48a is less than the length of the first part of the second connecting member 48b, which can make both ends of the first to fourth alignment rods lie on the same plane.

[0046] Figure 4 and Figure 5 shows a working schematic diagram of the alignment device according to an embodiment of the present invention. The following will refer to Figure 4 and Figure 5 to describe in detail the working principle of the alignment device according to an embodiment of the present invention.

[0047] The first alignment structure 2 includes a first alignment rod 21 and a second alignment rod 22 arranged in parallel along the transverse direction (X direction). Both ends of the first alignment rod 21 and the second alignment rod 22 are connected to the first drive belt 41a and the second drive belt 41b respectively through connecting members. When the first drive belt 41a and the second drive belt 41b rotate, the first alignment rod 21 and the second alignment rod 22 can be driven to move in opposite directions.

[0048] The second alignment structure 3 includes a third alignment rod 31 and a fourth alignment rod 32 arranged in parallel along the longitudinal direction (Y direction). Both ends of the third alignment rod 31 and the fourth alignment rod 32 are connected to the first drive belt 41a and the second drive belt 41b respectively through connecting members. When the first drive belt 41a and the second drive belt 41b rotate, the third alignment rod 31 and the fourth alignment rod 32 can be driven to move in opposite directions.

[0049] First, the motor drives the first drive wheel and the second drive wheel to rotate counterclockwise. Since the meshing positions of the first drive belt and the second drive belt on the first drive wheel and the second drive wheel are different, the rotation directions of the first drive belt and the second drive belt are just opposite, that is, the first drive belt rotates counterclockwise and the second drive belt rotates clockwise. Then, the first to fourth alignment rods move towards the edge of the bearing surface under the drive of the first drive belt and the second drive belt, as Figure 4 shown. Finally, the first to fourth alignment rods stop at the edge position of the bearing surface, and the cross-sectional area between the first to fourth alignment rods increases, which can enable the target object to accurately fall into the cross-sectional area between the first to fourth alignment rods.

[0050] After the target object falls into the cross-sectional area between the first to fourth alignment rods, the motor drives the first drive wheel and the second drive wheel to rotate clockwise, the first drive belt rotates clockwise, and the second drive belt rotates counterclockwise. The first to fourth alignment rods move closer to each other, as Figure 5As shown in the figure. As the cross-sectional area between the first to fourth alignment rods gradually decreases, the first to fourth alignment rods can align the target object both horizontally and vertically, causing the target object to accurately fall into the predetermined position A.

[0051] It should be noted that the embodiments of the present invention do not specifically limit the types of the driving wheel, the auxiliary wheel, and the synchronous wheel. The driving wheel, the auxiliary wheel, and the synchronous wheel can be sprocket wheels, and the transmission belt is a chain; or the driving wheel, the auxiliary wheel, and the synchronous wheel are track wheels, and the transmission belt is a track; or the driving wheel, the auxiliary wheel, and the synchronous wheel are pulley wheels, and the transmission belt is a belt. The types of the driving wheel, the auxiliary wheel, and the synchronous wheel and the specific transmission method can be selected according to the actual use and production conditions.

[0052] In summary, in the alignment device provided by the embodiments of the present invention, it includes a carrying platform, on which there is a carrying surface for placing the target object. At least one set of horizontal first alignment structures and at least one set of vertical second alignment structures are fixedly arranged on the carrying platform. The first alignment structures and the second alignment structures are connected to a control device. The control device controls the first alignment structures to perform horizontal alignment and controls the second alignment structures to perform vertical alignment, so that the target object can accurately fall into the predetermined position, realizing the automatic alignment of the target object and improving the efficiency of automated operations.

[0053] In a preferred embodiment, the control device includes a first transmission belt and a second transmission belt arranged vertically at intervals, and a first driving wheel and a second driving wheel. The first driving wheel and the second driving wheel rotate in the same direction at the same speed under the drive of a motor. The meshing positions of the first transmission belt and the second transmission belt with the first driving wheel and the second driving wheel are different. Therefore, when the motor drives the first driving wheel and the second driving wheel to rotate, the rotation directions of the first transmission belt and the second transmission belt are exactly opposite, that is, when the first transmission belt rotates clockwise, the second transmission belt rotates counterclockwise; when the first transmission belt rotates counterclockwise, the second transmission belt rotates clockwise. Both the first alignment structures and the second alignment structures include two alignment rods arranged in parallel. Both ends of each alignment rod are respectively connected to the first transmission belt and the second transmission belt. Therefore, when the first transmission belt and the second transmission belt rotate, both ends of each alignment rod can move in the same direction. It achieves the beneficial effect of controlling both ends of each alignment rod to move in the same direction by one motor.

[0054] In a preferred embodiment, for two alignment rods moving along the same straight line, since the transmission belts on the same side to which they are connected are different, the moving directions of the two alignment rods are exactly opposite during the rotation of the transmission belts. Therefore, during the rotation of the transmission belts, the two alignment rods moving along the same straight line will move away from or towards each other. The automatic alignment of the target object is realized through the convergence and divergence between the alignment rods in two directions, and the structure is simpler.

[0055] In a preferred embodiment, a conveyor belt guard is further provided on the conveyor belt. The conveyor belt guard is used to improve the load-bearing capacity of the conveyor belt and limit the conveyor belt at the same time.

[0056] In a preferred embodiment, both ends of each alignment rod are respectively connected to the conveyor belt through connectors, improving the stability of the alignment rod.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
