The transmission mechanism 2 is in transmission connection with the plurality of brackets 1 and is used for driving any one of the brackets 1 to slide according to the width of the PCB and the scanning path of the PCB optical scanner, so that the plurality of brackets 1 are close to or far away from each other, namely, each bracket 1 can slide along the direction perpendicular to the conveying direction of the conveying channel 11. In this embodiment, due to the arrangement of the plurality of conveying channels 11, the optical scanner can scan and detect the plurality of PCB boards in the plurality of conveying channels 11 at the same time every time the optical scanner moves, and the detection efficiency is high. In addition, through the setting of drive mechanism 2, drive mechanism 2 can be according to the width of PCB board real-time regulation each transfer passage 11's width to make conveyer can carry out the material loading to the PCB board of multiple specification and detect, adapt to the diversified demand of production environment. Furthermore, since the transmission mechanism 2 can drive any one of the brackets 1 to slide, the width covered by all the conveying paths 11 can be adjusted according to the scanning path (e.g., L1-L2) of the optical scanning gun, so that the width of the conveying device composed of several conveying paths 11 can be adapted to the scanning path of the optical scanner. In addition, in the transmission mechanism 2 of the present embodiment, a gear mechanism, a screw mechanism, a belt mechanism, and the like can be selectively used.

The following description will take the conveying device with two conveying channels 11 as an example

Specifically, the conveying device in this embodiment further includes a pair of slide rails 3 disposed oppositely, two ends of the plurality of brackets 1 are slidably connected to the pair of slide rails 3, respectively, and the transmission mechanism 2 drives the brackets 1 to slide along the slide rails 3.

More specifically, as shown in fig. 1, the number of the racks 1 is four, and the racks are respectively a first rack 12 located at both left and right ends and a second rack 13 located between the two first racks 12, and a transfer passage 11 is formed between the first racks 12 and the second racks 13 adjacent to each other, and therefore, the transfer apparatus in the present embodiment has two transfer passages 11. The transmission mechanism 2 comprises a first transmission rod 20 connected with the two first brackets 12 and a second transmission rod 21 connected with the two second brackets 13, the first transmission rod 20 is used for driving the two first brackets 12 to approach or depart from each other, and the second transmission rod 21 is used for driving the two second brackets 13 to approach or depart from the first brackets 12 at the corresponding ends respectively. Preferably, the first transmission rod 20 and the second transmission rod 21 in this embodiment are both bidirectional screws, and taking the second transmission rod 21 as an example, two transmission nuts are provided thereon, and the two transmission nuts are respectively connected with the two second brackets 13, when the two transmission channels 11 need to be narrowed, the motor on the second transmission rod 21 or the operating handle at one end is started, so that the two transmission nuts move in opposite directions, thereby driving the two second brackets 13 to respectively approach the first brackets 12 at the two ends, and similarly, when the two transmission channels 11 need to be widened, the motor on the second transmission rod 21 or the operating handle at one end is started, so that the two transmission nuts move in opposite directions, thereby driving the two second brackets 13 to respectively keep away from the first brackets 12 at the two ends. In addition, when the scanning path of the optical scanner changes, the first driving rod 20 can be activated, and the two first supports 12 are driven to approach or move away from each other by the two driving nuts of the first driving rod 20.
