[0030] PCB, full name Printed Circuit Board, is the bearing part of electronic components. It is made through circuit diagrams and drawings, supporting circuit elements and realizing the function of interconnecting circuit elements. In the PCB manufacturing process, the PCB needs to be sent to the AVI machine for inspection. AVI inspection is mainly used for appearance defects such as green oil pads, exposed copper, depressions, convex copper, whitening, broken green oil bridges, open circuits, short circuits, gaps, foreign matter, etc. In order to better realize the quality information control of products in production, after AVI inspection, label paper needs to be glued to the inspected PCB board for later information traceability.

[0031] However, in the current label paper bonding process, production personnel are required to take the label paper from the AVI machine and then bond it to the PCB board. This process not only takes a lot of time, but is also prone to bonding errors, the label paper does not correspond to the PCB board, and leads to errors in the later quality information control. Based on this, the present application provides a label paper conveying system for PCB boards. Example

[0032] Reference Figure 1-Figure 5 The utility model provides a label paper conveying system for PCB boards, comprising:

[0033] The conveyor line 2, the inlet end of the conveyor line 2 is connected to the outlet end of the AVI inspection machine 1; the AVI inspection machine 1 can be an existing AVI inspection machine 1, which is mainly used to inspect the quality of PCB boards.

[0034] The conveyor line 2 is provided with a label printer 4, and the label printer 4 is arranged downstream of the inlet end of the conveyor line 2;

[0035] A control device, the control device is electrically connected to the label printer 4 and the AVI detector 1. The drawings of the present application do not show a control device.

[0036] Specifically, the label printer 4 is spaced L meters from the entrance end of the conveyor line 2, where L is 1 meter to 3 meters.

[0037] The label printer 4 is at a certain distance from the outlet of the AVI inspection machine 1, so that after the inspected PCB board flows out from the outlet of the AVI inspection machine 1, the control device has enough time to send a signal to the label printer 4, so that the label printer 4 receives the inspection information fed back by the AVI inspection machine 1 and prints the relevant information on the label paper. Specifically, the label paper can include all the information of the inspected PCB board, such as the production date, batch number, whether the product quality is qualified, etc.

[0038] In actual applications, a material detector may be provided at the outlet of the AVI inspection machine 1 to detect whether a PCB board flows out. The material detector is electrically connected to the control device and can feed back a signal to the control device.

[0039] This is a label paper conveying system for PCB boards. During operation, the control device can receive the signal fed back by the AVI detection machine 1.

The detected PCB board enters the conveying line 2 and flows through the label printer 4. The label printer 4 sends out the printed label paper so that the label paper falls on the PCB board, realizing a one-to-one correspondence between the PCB board and the label paper. Then the PCB board and the label paper continue to be sent out by the conveying line 2 or sent into the label bonding machine for bonding. The conveying system can make the PCB board correspond to the label paper one-to-one, saving the step of manually taking the label paper, and can avoid the defect that the label paper does not correspond to the PCB board, resulting in errors in the quality information control in the later stage.
