Specifically, the position correcting baffle comprises a first arc baffle 71 and a second arc baffle 70, the first arc baffle and the second arc baffle are sequentially connected and arranged along the conveying direction of the workpiece, the circle center of the arc where the second arc baffle is located coincides with the circle center of the circle where the conveying direction of the workpiece is located, the second arc baffle is arranged on one side of the conveying part of the workpiece, one end of the first arc baffle is connected with the second arc baffle, the other end of the first arc baffle is turned over to form an arc towards one side far away from the conveying part of the workpiece, and the diameter of the arc where the first arc baffle is smaller than that of the arc where the second arc baffle is located.
In one embodiment, the second arc-shaped baffles of the two groups of position correcting baffles have the same arc-shaped diameter, and when the plane of the protrusions at the two sides of the suction nozzle is perpendicular to the tangential line of the workpiece in the conveying direction, the protrusions at the two sides of the suction nozzle are still clamped between the second arc-shaped baffles of the two groups of position correcting baffles.
In a preferred embodiment, the arc diameters of the second arc baffles in the two groups of position correcting baffles are different, and by setting the second arc baffles in the two groups of position correcting baffles to arc baffles with different radians and different diameters, when the plane where the outer edge protrusions on two sides of the suction nozzle are located is perpendicular to the tangent line in the conveying direction of the workpiece, the outer edge protrusions on one side of the suction nozzle firstly prop against the second arc baffles with larger arc diameters, and in the continuous movement of the suction nozzle in the conveying direction of the workpiece, the plane where the outer edge protrusions on two sides of the suction nozzle are located is tangent to the circle where the conveying direction of the workpiece is located by rotating the outer edge protrusions on the other side of the suction nozzle.
