The number of the rollers 10 is plural, each of the rollers 10 is substantially cylindrical, and each of the rollers 10 extends in the first direction L1. Each of said rollers 10 has an axis parallel to said first direction L1, about which said roller 10 can rotate. The plurality of rollers 10 are arranged in a second direction L2, wherein the second direction L2 is perpendicular to the first direction L1.

In other embodiments, the length, diameter, and axial distance of the roller 10 are not limited, and may be adjusted according to parameters such as a conveying speed and a hardness of the circuit board 40. For example, the length of the roller 10 along the first direction L1 is 800mm to 1000mm, the diameter of each roller 10 is 30mm to 50mm, and the axial distance between two adjacent rollers 10 is 40mm to 60 mm. In one embodiment, the length of each of the rollers 10 along the first direction L1 is 850mm, the diameter of each of the rollers 10 is 40mm, and the axial distance between two adjacent rollers 10 is 50mm, so that the circuit board 40 is uniformly stressed during the transmission process, and the circuit board 40 is prevented from being bent to cause the jamming.

The conveyor belt 20 has toughness, and the material of the conveyor belt 20 may be polytetrafluoroethylene, polyvinyl chloride, or the like. The conveyor belt 20 is used for carrying and conveying the circuit board 40.

The number of the conveyor belts 20 is plural, each of the conveyor belts 20 is in an elliptical ring shape and is sleeved on the plurality of rollers 10 arranged along the second direction L2, and the plurality of conveyor belts 20 are arranged along the first direction L1.

The conveyor belts 20 are movably disposed on the roller 10, that is, the distance between two adjacent conveyor belts 20 can be adjusted according to parameters such as the length of the circuit board 40 and the width of the circuit board 40, so as to convey circuit boards 40 with different sizes, thereby increasing the universality of the conveyor 100.

In other embodiments, the number of the conveyor belts 20 may be set according to needs, for example, adjusted according to parameters such as the hardness of the circuit board 40, the length of the circuit board 40, the width of the circuit board 40, and the like.

When the circuit board 40 is placed on the conveyor belt 20, the roller 10 rotates along the axis to drive the conveyor belt 20 to move along the first direction L1, and the movement of the conveyor belt 20 drives the circuit board 40 to convey along the first direction L1.

Further, the conveyor belt 20 has a cross section perpendicular to the second direction L2, and the length of the line of the cross section on the side facing away from the roller 10 is smaller than the length of the line of the cross section on the side close to the roller 10.

The length D2 of the second line segment 214 is relatively long, which can increase the contact area between the driving surface 212 and the roller 10, thereby increasing the friction between the roller 10 and the belt 20, and further facilitating the movement of the belt 20 by the roller 10; the relatively short length D1 of the first line segment 234 reduces the area of the carrying surface 232, thereby reducing the contact area between the conveyor belt 20 and the circuit board 40, reducing the friction between the conveyor belt 20 and the circuit board 40, and preventing the circuit board 40 from being scratched during the conveying process.
