Description

PCB labeling auxiliary tool

Technical Field

The utility model belongs to the technical field of PCB processing, and particularly discloses an auxiliary fixture for labeling a PCB.

Background

There are many types of existing PCB boards (Printed Circuit Board, printed circuit boards), and in order to facilitate distinguishing between different PCB boards, relevant information of the PCB boards is generated into a label, and then the label is attached to a corresponding position of the corresponding PCB board. Automatic labelling of PCBs is typically achieved in the prior art by means of labelling devices.

When an automatic labeling device is used for labeling, labeling is usually performed after a stack of PCB boards are stacked together. However, because the PCB itself is plate-shaped, the difference between the front and back sides is small, and not all labeling apparatuses can detect the front and back directions of the PCB. This results in the situation that personnel place and the PCB is reversed when the suppliers supply materials for packaging, and the labels are attached to the back surface of the PCB when the labels are attached. In addition, in the conventional operation process, the SMT labeling has a certain probability of causing label offset due to the fact that the PCB is not placed neatly.
