In addition, the second driving assembly 22 drives the blocking member 21 to move downward, so that the blocking member 21 is located at the second position, and at this time, the upper end of the blocking member 21 is lower than the upper end of the lifting mechanism 1, and the blocking member 21 can allow the PCB to pass through.
As shown in fig. 2, the blocking mechanism 2 includes a mounting assembly 24, the mounting assembly 24 is connected with the jacking mechanism 1 and the second driving assembly 22 respectively, and by setting the mounting assembly 24, the blocking mechanism 2 is more firmly connected with the jacking mechanism 1, and the blocking mechanism 2 is more convenient to disassemble and assemble with the jacking mechanism 1.
In addition, the blocking mechanism 2 is constantly impacted by the PCB during operation, and thus, the accuracy of movement of the blocking mechanism 2 in the up-down direction is affected. To solve this problem, as shown in fig. 2, the blocking mechanism 2 further includes a first guide mechanism 23, the first guide mechanism 23 being provided between the mounting assembly 24 and the blocking member 21, the first guide mechanism 23 being for guiding the blocking member 21 to move the blocking member 21 in the up-down direction.

In addition, in actual production, the sizes of the PCB are generally inconsistent, which can lead to the center of the PCB deviating from the middle of the supporting device, thereby affecting the dispensing accuracy. To solve this problem, as shown in fig. 1 and 2, the relative positions of the blocking portion 211 and the connecting portion 212 along the movement direction of the PCB board are adjustable. When the size of the PCB is bigger, the blocking part 211 is adjusted in the direction away from the jacking mechanism 1, when the size of the PCB is smaller, the blocking part 211 is adjusted in the direction close to the jacking mechanism 1, and the center of the PCB can be ensured to be positioned in the middle of the supporting device by adjusting the distance between the blocking part 211 and the jacking mechanism 1, so that the dispensing precision is ensured.
