For example, the requirements for the effective activity space of the robot arm for visual recognition and grasping are reduced because the objects are basically in the middle), etc. The first conveyor belt and the second conveyor belt rotate in different directions to meet different needs. When rotating in the same direction, they realize the function of an ordinary conveyor belt. When the two conveyor belts rotate in opposite directions, they can "rub apart" the objects, that is, rely on the conveyor belts on both sides to give the objects friction forces in different directions, so that the stacked objects can be separated, which is convenient for subsequent processing. Separation refers to the object can be only a single object on the vertical plane along the moving direction of the conveyor belt, which makes the conveyor belt convey a single object instead of multiple objects when the object falls out, which is convenient for subsequent processing, thereby simplifying the classification of multiple objects into the classification of single objects.

[0032] The first transmission mechanism includes a second motor 10, the second motor 10 is mounted on the first support plate 1, the output shaft of the second motor 10 is drivingly connected to a fourth transmission wheel 8, the fourth transmission wheel 8 is rotatably mounted on a side of the first support plate 1 perpendicular to the direction of motion transmission, the surface of the fourth transmission wheel 8 is drivingly connected to a second conveyor belt 9, the other side of the second conveyor belt 9 is drivingly connected to a third transmission wheel 7, the third transmission wheel 7 is rotatably mounted on the other side of the first support plate 1 perpendicular to the direction of motion transmission;

[0033] Specifically, the second motor 10 is started, the second motor 10 rotates to drive the fourth transmission wheel 8 to rotate, and the fourth transmission wheel 8 rotates to drive the second transmission belt 9 to rotate;

[0034] A second conveying mechanism is installed on the surface of the second support plate 2, and the second conveying mechanism includes a first motor 6, which is installed on the second support plate 2. The output shaft of the first motor 6 is connected to the second conveying wheel 4, which is rotatably installed on one side of the second support plate 2. The surface of the second conveying wheel is connected to the first conveyor belt 5, and the other side of the first conveyor belt 5 is connected to the first transmission wheel 3, which is rotatably installed on the other side of the second support plate 2.

[0035] Specifically, the first motor 6 is started, the first motor 6 rotates to drive the second transmission wheel 4 to rotate, and the second transmission wheel 4 rotates to drive the first transmission belt 5 to rotate;

[0036] The first conveyor belt 5 and the second conveyor belt 9 are arranged at an obtuse angle, and the first conveyor belt 5 and the second conveyor belt 9 adopt an angle shape of 90° to 179°. The surfaces of the first conveyor belt 5 and the second conveyor belt 9 adopt wavy anti-slip patterns. The relative inner sides of the first conveyor belt 5 and the second conveyor belt 9 are arranged to tilt downward, and the relative outer sides of the first conveyor belt 5 and the second conveyor belt 9 are arranged to tilt upward. The first conveyor belt 5 and the second conveyor belt 9 are generally low in the middle and high on both sides.

[0037] The surfaces of the first motor 6 and the second motor 10 are both fixed with plates, the fixing plate of the first motor 6 is fixedly connected to the second support plate 2 by bolts, and the fixing plate of the second motor 10 is fixedly connected to the first support plate 1 by bolts;

[0038] The second conveying mechanism and the first conveying mechanism are in an angle shape for naturally gathering objects toward the central axis due to gravity. The conveying ports of the second conveying mechanism and the first conveying mechanism are provided with matrix optical fiber sensors for sensing the transported objects. The detection results of the matrix optical fiber sensors are used to control the transmission direction of the bidirectional transmission mechanism. The matrix optical fiber sensors can be suspended at the conveying ports of the second conveying mechanism and the first conveying mechanism through a bracket. There is at least one bidirectional transmission mechanism for rubbing apart the stacked objects between the second conveying mechanism and the first conveying mechanism.

[0039] Specifically, when the matrix optical fiber sensor detects that objects are stacked together, the first motor 6 and the second motor 10 are started, and the first motor 6 drives the first conveyor belt 5 to rotate through the second conveyor wheel 4, and the second motor 10 drives the second conveyor belt 9 to rotate through the fourth conveyor wheel 8, so that the rotation direction of the second conveyor belt 9 is opposite to that of the first conveyor belt 5, thereby rubbing the objects apart and separating the objects, and then controlling the second motor 10 to rotate in the opposite direction through the fourth conveyor wheel 8 to drive the second conveyor belt 9 to rotate in the same direction as the first conveyor belt 5, thereby dispersing and conveying the objects.

[0040] Through the above structural design, the first conveyor belt 5 and the second conveyor belt 9 are designed in a manner of an angle of degrees, so that the first conveyor belt 5 and the second conveyor belt 9 are overall in a shape of "low in the middle and high on both sides", which makes the objects on the conveyor belt naturally gather towards the central axis due to gravity, avoiding the objects from leaning to one side or even rolling out, and facilitating the processing of objects on the conveyor belt, such as visual recognition and grasping. The requirements for the effective activity space of the robot arm are reduced, because the objects are basically in the middle, etc. The first conveyor belt 5 and the second conveyor belt 9 rotate in different directions, which can meet different needs. When rotating in the same direction, the function of an ordinary conveyor belt is realized. When the two conveyor belts rotate in opposite directions, the objects can be "rubbed apart", that is, relying on the conveyor belts on both sides to give the objects friction in different directions, the objects stacked together can be separated, which is convenient for subsequent processing. Separation refers to the object can be only a single object on the vertical plane along the active direction of the conveyor belt, which makes the conveyor belt convey a single object instead of multiple objects when the object falls out, which is convenient for subsequent processing, thereby simplifying the classification of multiple objects into the classification of single objects;

[0041] The bidirectional transmission method of the transmission mechanism includes the following steps:

[0042] Step 1: The matrix optical fiber sensor detects the current object to be transmitted;

[0043] Step 2: The transmission mechanism with a bidirectional transmission function enters corresponding working states according to the stacking conditions of the objects. If the objects to be transmitted are scattered or slightly in contact, the forward constant-speed transmission state is started. If the contact area percentage of the objects to be transmitted exceeds a threshold value 1, the forward differential transmission state is started until the objects to be transmitted are scattered or slightly in contact, and the state is changed to the forward constant-speed transmission state. If the contact area percentage of the objects to be transmitted exceeds a threshold value 2, the bidirectional transmission state is started until the objects to be transmitted are scattered or slightly in contact, and the state is changed to the forward constant-speed transmission state. The threshold value 2 is greater than the threshold value 1.

[0044] Step 3: In the forward uniform speed transmission state, the first conveyor belt (5) and the second conveyor belt (9) move forward uniformly according to the set direction, and the relative positions of the objects to be transmitted are maintained;

[0045] Step 4: in the forward differential transmission state, the first conveyor belt (5) and the second conveyor belt (9) move in a forward differential speed according to a set direction, and the relative positions of the objects to be transmitted change;

[0046] Step 5: In a bidirectional transmission state, the first conveyor belt (5) moves forward according to a set direction, and the second conveyor belt (9) moves backward according to a set direction, so that the objects to be transmitted form a relative movement.

[0047] Example 2

[0048] Further, based on Example 1, an adjustment mechanism for adjusting the angle between the first support plate 1 and the second support plate 2 is fixedly installed at the bottom of the first support plate 1 and the second support plate 2;

[0049] The adjustment mechanism includes a rotating seat, which is located on the central axis of the first support plate 1 and the second support plate 2. Two mounting blocks 11 are fixedly installed on the bottom of the rotating seat. Grooves are provided on both sides of the rotating seat. A rotating shaft is rotatably connected to the inner side of each groove. A rotating plate is fixedly connected to the surface of the rotating shaft. The first support plate 1 is fixedly connected to the other side of the rotating plate. The second support plate 2 is fixedly connected to one side of the other rotating plate. A screw for fixing the position of the rotating shaft is connected to the internal thread of the rotating shaft, and the surface of the screw is threadedly connected to the rotating seat. A pointer is fixedly connected to one side of the rotating shaft extending to the outside of the rotating seat. The pointer rotates on a scale installed on the surface of the rotating seat. The included angle between the first support plate 1 and the second support plate 2 is marked by rotating the pointer on the scale.

[0050] Specifically, the first support plate 1 and the second support plate 2 are pulled to rotate, and the rotation of the first support plate 1 and the second support plate 2 drives the respective shafts to rotate, and the rotation of the shaft drives the pointer on the scale to rotate, indicating the scale on the scale;
