And controlling the working state of the conveyor belt on each guide rail according to the detection results of the feeding sensor and the discharging sensor.

As shown in fig. 2, in the present embodiment, the number of the label feeding assemblies 20 is plural and is disposed on both sides of the material transporting assembly 10, respectively. The number of label feed assemblies 20 may be selected based on the type of label desired to be applied by the PCB.

As shown in fig. 2, in the present embodiment, the multi-axis robot 30 is installed above the material transporting assembly 10.

The working principle is briefly described:

as shown in fig. 2, in operation, the pitch positions of the second rail 12, the third rail 13, and the fourth rail 14 are adjusted according to the size of the PCB, so that a first track for transporting the PCB is formed between the first rail 11 and the second rail 12, and a second track for transporting the PCB is formed between the third rail 13 and the fourth rail 14. Each PCB moves under the load of the two conveyor belts, is intercepted by the stop unit when the PCB reaches a preset labeling point, and the guide rails are further brought together to clamp the PCB for positioning, at which point the labeling sensor detects that the PCB is in place, the multi-axis robot 30 grabs the label from the label feed assembly 20 and attaches the label to the PCB, and then the stop unit releases the PCB, which is transferred from the rail flow to the next station.

For example, in the present embodiment, the PCB conveyance on the first track constituted by the first rail 11 and the second rail 12 is taken as an example. The position of the second rail 12 is adjusted in advance according to the size of the PCB so that the width of the first rail matches the width of the PCB. When the PCB enters the first rail from the right end, the first feeding sensor 113 detects the PCB entering, the first conveyor belt and the second conveyor belt start to operate, and the first stopper rod 1112 on the first stopper unit 111 is lifted, both sides of the PCB are respectively moved toward the right end under the support of the conveyor belt until being intercepted by the first stopper rod 1112, at this time, the first labeling sensor 112 detects that the PCB has reached the labeling point, the second rail 12 is moved toward the left again by a small extent, the first rail is narrowed to clamp the PCB, and the multi-axis robot 30 adsorbs the label from the label feeding assembly 20 and attaches to the PCB. After the labeling is completed, the second guide rail 12 moves right by a small extent to loosen the PCB, then the first material blocking rod 1112 descends to release the PCB, the PCB continues to move forward until reaching the position of the first material discharging sensor 114, the first material discharging sensor 114 detects that the PCB reaches the material receiving point of the preset next station, and the first conveyor belt and the second conveyor belt stop to act and wait for the PCB to be taken away.

The dual-track labeling machine 100 constructs the dual-track material transmission assembly 10 which can be flexibly adjusted according to the size of the PCB, and is matched with the multi-axis manipulator 30 and the label feeding assembly 20 to realize automatic labeling of the PCB, so that the problem of applicability of the PCB with different sizes is solved, and two PCBs can be conveyed side by side to improve the working efficiency.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
