[0001] The utility model belongs to the technical field of vision detection, and particularly relates to a vision detection platform. Background Art

[0002] With the development of technology and the progress of living standards, in the field of appearance defect detection, machine vision detection has gradually replaced manual detection, greatly improving the detection efficiency and accuracy. Since there are many types of appearance defects, in order to enable the vision detection device to detect multiple defect types of the object to be detected, it is required that the platform where the object to be detected is located has a high degree of freedom and can detect multiple objects simultaneously.

[0003] However, most of the existing detection platforms are of the flow channel type or the module type. When the object to be detected moves on the platform, its plane is still parallel to the tabletop, making it difficult to achieve multi-station and multi-degree-of-freedom detection. That is, the degree of freedom of movement of the object to be detected on the detection platform is limited, making it difficult to achieve multi-directional imaging and unable to detect various types of defects.

[0004] Even if the existing detection platforms have a certain flipping function, they need to be combined with multiple structures to achieve it. This not only increases the volume and weight of the platform, but also reduces the detection efficiency, increases the production and detection costs, and is not convenient for popularization and use.

[0036] Among them, the first direction can be the length direction of the mounting base plate 1.

[0037] Specifically, the at least four support plates 5 are located in the same plane, and the plane where the at least four support plates 5 are located is parallel to the mounting base plate 1. It can be understood that in the embodiments of the present utility model, it is not limited that the object to be detected is directly placed on the support plate 5, and a tray can also be arranged on the support plate 5, and the object to be detected is placed on the tray.

[0038] Among them, the vision detection platform further includes a slewing mechanism 4. The slewing mechanism 4 is arranged on the mounting base plate 1 and is connected to the support plate 5. The slewing mechanism 4 is used to drive the support plate 5 to rotate self - sufficiently to drive the object to be detected to rotate self - sufficiently, so that the vision detection device can detect the side of the object to be detected, improving the detection quality.

[0039] Among them, the slewing mechanism 4 includes a slewing drive unit 41, a belt drive assembly 42 and a hollow slewing platform 43.

[0041] Among them, the slewing drive unit 41 can be a motor, and the drive end of the slewing drive unit 41 can be understood as the motor shaft of the motor, specifically the motor shaft of a servo motor.

By providing the stage base 2, a stable setting position is provided for the mounting base plate 1, and at the same time, it can support the mounting base plate 1 to flip. It should be noted that the flipping of the mounting base plate 1 means that the mounting base plate 1 rotates with the rotation connection point between the mounting base plate 1 and the stage base 2 as the rotation center. In the present invention, the axis of flipping of the mounting base plate 1 is perpendicular to the axis of self-rotation of the support plate 5.

[0045] Specifically, the vision detection platform further includes a flipping mechanism 3. The flipping mechanism 3 is arranged on the stage base 2, and the driving end of the flipping mechanism 3 is connected to the mounting base plate 1. By providing the flipping mechanism 3, power can be provided to the mounting base plate 1 to rotate with the rotation connection point between the mounting base plate 1 and the stage base 2 as the rotation center.

[0046] In some possible implementation embodiments disclosed in the present invention, refer to Figure 2 As shown, the belt drive assembly 42 includes a driving wheel, a driven wheel and a belt. The belt is respectively connected to the driving wheel and the driven wheel. The driving end of the rotary drive unit 41 is connected to the driving wheel. The rotary drive unit 41 is used to drive the driving wheel to rotate, so as to drive the driven wheel to rotate through the belt.

[0052] It should be noted that the belt drive assembly 42 transmits torque through the belt. Since the belt has a certain flexibility, the positions of the two long pulley shafts and the two short pulley shafts can be finely adjusted. On the one hand, it can ensure that the concentricity of the long pulley shaft and the short pulley shaft with the input end of the hollow slewing platform 43 is consistent, improving the installation accuracy; on the other hand, it can ensure that the center lines of the long pulley shaft and the short pulley shaft are coplanar, that is, it can ensure that the connection line of the centers of multiple objects to be detected is a straight line, improving the detection quality.

The idler pulley is rotatably arranged on the idler pulley seat and is in contact with the belt. By setting the idler pulley assembly 44, the belt can be tensioned, the friction between the belt and the driving wheel and the driven wheel can be increased, and the working stability of the belt drive assembly 42 can be improved. Thus, it can ensure that the rotation angles of multiple objects to be detected are the same, improving the detection quality.

[0054] Among them, in the embodiment of the present utility model, four idler pulley assemblies 44 are provided. The first-stage transmission part is tensioned by two idler pulley assemblies 44, and the two second-stage transmission parts are respectively tensioned by one idler pulley assembly 44.

The first end of the slewing shaft 45 is connected to the hollow slewing platform 43, and the second end of the slewing shaft 45 is connected to the suction cup mounting plate 46. A suction cup is provided on the suction cup mounting plate 46, and the suction cup is used to adsorb the support plate 5.

[0058] Among them, the slewing shaft 45 is arranged between the hollow slewing platform 43 and the suction cup mounting plate 46. The suction cup mounting plate 46 is relatively fixed to the slewing shaft 45. The output end of the hollow slewing platform 43 is connected to the slewing shaft 45, and the output end of the hollow slewing platform 43 is used to drive the slewing shaft 45 and the suction cup mounting plate 46 to rotate.

[0059] Specifically, the suction cup mounting plate 46 is adapted to rotate around the axis of the slewing shaft 45.

[0060] Among them, a suction cup is provided on the suction cup mounting plate 46, and the suction cup can adsorb the support plate 5. In the embodiments of the present utility model, by providing the suction cup mounting plate 46, a stable mounting foundation is provided for the suction cup, ensuring that the suction cup can be firmly mounted at the specified position and will not easily shake or fall off; at the same time, it can also help maintain the accurate position of the suction cup in the working space, thereby ensuring the accuracy of the suction and operation of the suction cup on objects such as workpieces.

[0061] In some possible embodiments disclosed by the present utility model, the slewing mechanism 4 further includes a rotary joint. The rotary joint is arranged inside the hollow slewing platform 43. The rotary joint is used to connect the air pipe, and the rotary joint is also connected to the slewing shaft 45. The slewing shaft 45 is a hollow structure, and the rotary joint supplies air to the suction cup through the slewing shaft 45. By providing the rotary joint, continuous transmission of gas can be achieved between the air pipe and the slewing shaft 45, ensuring that the gas supply is not interrupted while the slewing shaft 45 is rotating.

[0062] Among them, a through hole is opened on the outer shell of the hollow slewing platform 43, and the air pipe can extend into the hollow slewing platform 43 through the through hole to be connected to the rotary joint.

[0063] Specifically, the rotary structure is also connected to the slewing shaft 45. The slewing shaft 45 is a hollow structure, so that the air pipe can smoothly transport gases such as compressed air from the gas source to the suction cup through the rotary joint and the slewing shaft 45. It can be understood that when gas is introduced into the suction cup, such as pumping out the air inside the suction cup, a negative pressure will be formed inside the suction cup, that is, a pressure state lower than the atmospheric pressure. Under the action of the atmospheric pressure, the suction cup will tightly adsorb the support plate 5. When it is necessary to release the support plate 5, an appropriate amount of gas is introduced into the suction cup through the air pipe to make the pressure inside the suction cup return to normal, thereby releasing the adsorption.

[0064] In some possible embodiments disclosed by the present utility model, refer toFigure 2 As shown, the rotary mechanism 4 also includes an air pipe wire board 6, which is arranged on the mounting base plate 1 and is used to fix the air pipe.

[0069] The reducer 32 may be a harmonic reducer 32 . The reducer 32 can reduce the rotation speed and significantly increase the torque output by the flip drive unit 31 , thereby ensuring that the mounting base 1 can be flipped relative to the stage base 2 .

[0070] The driving end of the flip driving unit 31 is connected to the mounting base plate 1 through a reducer 32 and a transition flange 33 , and the flip driving unit 31 is used to drive the mounting base plate 1 to rotate with the driving end of the flip driving unit 31 as the rotation center.
