     The extending direction of the sliding rail  15  is the same with the moving direction of the connection rail  14 , and is perpendicular to the extending direction of the operation rail  12 .

The drive module is connected with the determination module and the distribution module and is configured to drive the distribution module to move between the operation rail  12  and the common conveying rail  13  based on the result of the determination. 
     When the connection rail  14  is positioned at one side of the common conveying rail  13  and the operation rail  12 , a supplied material first flows into the connection rail  14 . Then, it is determined based on a determination result of the determination module, whether the material  200  is to be conveyed onto the common conveying rail  13  or the operation rail  12 . After this determination, the drive module drives the connection rail  14  to move to the determined position and conveys the material  200  to the determined position. It needs to be noted that, the determination module may include a Camera Compact Module (CCM), a sensor, etc. The operation unit corresponds to the common conveying rail  13 , and may perform operations such as processing and detection on the material  200 . 
     For example, when there is a material  200  being processed on the operation rail  12  of one material conveying device  100 , the distribution module at one side of the one material conveying device  100  conveys a next material  200  after the material  200  to the common conveying rail  13  of the one material conveying device  100 , and conveys the next material  200 , by a distribution module between two material conveying devices  100  adjacent to each other , to the operation rail  12  or the common conveying rail  13  of another material conveying device  100 . 
     According to an embodiment of the present disclosure, the drive module may include a drive motor. The drive module may drive the connection rail  14  to move between the operation rail  12  and the common conveying rail  13  to allow the connection rail  14  to be in communication with the operation rail  12  or the common conveying rail  13 . The drive module can further improve the degree of automation. 
     According to an embodiment of the present disclosure, each material conveying device  100  includes one or more common conveying rails  13  and one or more operation rails  12 .

     It needs to be noted that, when there are three material conveying devices  100 , the three material conveying devices  100  are sequentially connected. If the operation rail  12  of a first material conveying device  100  is loaded with a material  200  being processed, a connection rail  14  may convey a next material  200  to be processed to the operation rail  12  or the common conveying rail  13  of a second material conveying device  100 . And when the next material  200  to be processed is conveyed to the common conveying rail  13  of the second material conveying device  100 , a connection rail  14  may continue to convey the next material  200  to be processed on the common conveying rail  13  of the second material conveying device  100  to the operation rail  12  of a third material conveying device  100 . In other words, the connection rail  14  may, based on whether the operation rail  12  of a material conveying device  100  is loaded with a material  200  being processed, choose to convey another material  200  to the operation rail  12  or the common conveying rail  13  of a next material conveying device  100  according to different needs and circumstances, for example, according to same, different, alternating or interlaced configurations of the operation units of multiple material conveying devices  100 .

In particular, the next material  200  is conveyed to a corresponding connection rail  14  along the conveying direction, and waits for further distribution on the connection rail  14 . 
     At S 3 , when the material  200  is being processed on the operation rail  12  of the first conveying unit  20  of the one material conveying device  100 , the connection rail  14  of the transfer assembly at the one side of the one material conveying device  100  conveys the next material  200  to the common conveying rail  13  of the one material conveying device  100 , and a connection rail  14  between two material conveying devices  100  adjacent to each other transfers the next material  200  to the first conveying unit  20  or the second conveying unit  30  of another material conveying device  100 , i.e., to the corresponding operation rail  12  or the corresponding common conveying rail  13 , that is, the connection rail  14  is driven to move to the common conveying rail  13  or the operation rail  12  based on a determination result at the step S 1 . 
     According to an embodiment of the present disclosure, when the operation units of two material conveying devices  100  adjacent to each other are the same, at step S 3 , a connection rail  14  at one side of one of the two material conveying devices  100  conveys a next material  200  to the common conveying rail  13  of the one of the two material conveying devices  100 .

     Optionally, at step S 4 , when the operation units of the two material conveying devices  100  adjacent to each other are the same, the connection rail  14  between the two material conveying devices  100  adjacent to each other conveys the processed material  200  to the common conveying rail  13  of the another material conveying device  100 ; and when the operation units of the two material conveying devices  100  adjacent to each other are not the same, the connection rail  14  between the two material conveying devices  100  adjacent to each other transfers the processed material  200  to the operation rail  12  of the another material conveying device  100 .

     In some specific embodiments of the present disclosure, the operation rail  12 , the common conveying rail  13  and the connection rail  14  are in parallel with each other, which can not only improve the structural compactness of the device and reduce the space occupation, but also improve the efficiency of the material  200  flowing between the connection rail  14  and the operation rail  12  or the common conveying rail  13 . 
     According to an embodiment of the present disclosure, two operation rails  12  of two material conveying devices  100  adjacent to each other are coaxial, and two common conveying rails  13  of the two material conveying devices  100  adjacent to each other are coaxial, which can improve the conveying efficiency of the material  200 . 
     Based on the above, the material distribution method for a material  200  according to embodiments of the present disclosure, can not only enable connection of multiple material conveying devices  100 , but also improve the efficiency of distributing and processing the material  200  so as to prevent the material  200  from waiting too long in the above connection of the multiple material conveying devices, which would otherwise cause jam.
