In order to ensure that the speed of the PCB is consistent with the conveying speed of the conveyor belt 315 when the inspection module starts scanning the PCB, at least 2/3 area of the PCB is required to be in contact with the conveyor belt 315.

As shown in fig. 3, the support structure 316 includes: a seat plate 3161, a support plate 3162, a driven roller 3163, a drive roller 3164, and a regulation roller 3165.

At this time, the seat plates 3161 are arranged bilaterally symmetrically, and the support plate 3162, the driven roller 3163, the drive roller 3164, and the adjustment roller 3165 are arranged between the two seat plates 3161. The regulating roller 3165 is positioned below the supporting plate 3162, the driven roller 3163 and the driving roller 3164 are distributed on two sides of the supporting plate 3162, and the driving roller 3164 is driven by the power structure 317 to pivot.

The power mechanism 317 may be a motor, and when the motor drives the driving roller 3164 to pivot, the driving roller 3164 drives the conveying belt 315 to perform a circular conveying motion around the driven roller 3163, the supporting plate 3162 and the adjusting roller 3165 by means of friction.

The supporting plate 3162 is used to sufficiently support the conveying surface of the conveying belt 315, and the supporting plate 3162 may be a single plate or may be composed of a plurality of portions arranged at intervals in a split manner. In the connection manner, both ends of the support plate 3162 may be mounted between the two seat plates 3161 by a connection member such as a bolt.

The drive roller 3164 and the driven roller 3163 are used to tension the conveying belt 315 from both sides. In this connection, the drive roller 3164 and the driven roller 3163 are each pivotally connected between two seat plates 3161. And one end of the driving roller 3164 is also in transmission connection with a motor installed at one side of the seat plate 3161. Thus, when the motor works, the driving roller 3164 in transmission connection with the motor synchronously pivots along with the motor, and the driven roller 3163 is linked with the driving roller 3164, so that the driving roller 3164 and the driven roller 3163 drive the conveying belt 315 to circularly convey through friction.

Thus, when the fine adjustment screw 31662 is rotated, the adjustment block 31661 connected thereto can be adjusted up and down according to the scale.

In one embodiment, the scale 31663 is an inverted U-shaped structure. At this time, the adjusting block 31661 is slidably disposed between the two U-shaped arms. In order to avoid the forward and backward shaking of the adjusting block 31661, the inner side walls of the two U-shaped arms are further provided with limiting parts which are abutted against the adjusting block 31661, so that the inner side walls of the U-shaped arms are of a step structure. When the fine adjustment screw 31662 is adjusted, the adjusting block 31661 slides up and down along the step structure.

The deviation rectifying structure 318 is used to assist the conveying belt 315 to keep at the set position, so as to prevent the deviation from affecting the conveying effect. The deviation rectifying structure 318 includes a plurality of deviation-proof rollers disposed below the conveying belt 315, and each deviation-proof roller is pivotally disposed below the conveying belt 315 and presses the bottom of the conveying belt 315. Correspondingly, a roller shaft which is convenient for the anti-deviation press roller to be in pivot connection is arranged below the conveying belt 315.

In one embodiment, the number of the deviation-preventing press rollers is four. The four deviation-preventing press rollers are symmetrically arranged on the left side and the right side below the conveying belt 315, two of the deviation-preventing press rollers are arranged close to one end of the conveying belt 315, and the other two deviation-preventing press rollers are arranged close to the other end of the conveying belt 315. Thus, the four deviation-preventing press rollers are matched with the adjusting roller 3165 to jointly realize the deviation correction of the conveying belt 315.

As shown in fig. 5, the guide mechanism 32 is used for further guiding the PCB conveyed by the feeding module 10 so that the PCB can be smoothly fed into the downstream conveying mechanism 31.

Wherein, guiding mechanism 32 includes: a guide bar 321 and a guide plate 322.

In this manner, the PCB board can be fed along the guide bar 321, the guide surface 3221 and the horizontal surface 3222 into the downstream conveying mechanism 31.

The pressing mechanism 33 is used for contacting with the PCB, so as to prevent the PCB from tilting, thereby facilitating the image acquisition of the subsequent inspection module. And the friction between the PCB and the conveyor belt 315 can be increased to ensure the stability of the scanning speed.

Wherein, hold-down mechanism 33 includes: at least one pressure roller 331. In one embodiment, the two pressing rollers 331 are provided, and the two pressing rollers 331 are disposed above the upstream end and the downstream end of the first conveying unit 311 and maintain a proper distance from the conveying belt 315 of the first conveying unit 311, the distance being equal to or slightly smaller than the thickness of the corresponding PCB panel. Meanwhile, the pressing roller 331 is composed of a roller shaft and a plurality of pressing rings axially arranged on the roller shaft at intervals. So, be favorable to reducing the area of contact of pinch roller 331 and PCB board, and then protect the PCB board.
