Embodiment 1

[0032] According to an embodiment of the present invention, a method for marking test results of a circuit board is provided, see figure 1 ,include:

[0033] Step B: Determine whether the circuit boards being conveyed are qualified according to the test results of the circuit boards, and detect whether the unqualified circuit boards during the conveyance have reached the predetermined position;

[0034] Step C: Stop conveying the circuit board when the circuit board reaches the predetermined position, and generate a distribution map of unqualified points on the circuit board according to the test results of the circuit board;

[0035] Step D: mark the unqualified points on the corresponding positions on the circuit board according to the distribution diagram.

[0036] In the embodiment of the present invention, the method for marking the test results of circuit boards is to determine whether the circuit boards being transported are qualified according to the detected test res...

Embodiment 2

[0038] According to another embodiment of the present invention, a method for marking test results of a circuit board is provided, see figure 2 , the method also includes:

[0039] Step E: Detect whether all unqualified points are marked, if not, continue to mark unqualified points on corresponding positions on the circuit board according to the distribution diagram.

[0040] Specifically: check whether there are unqualified points to mark, if so, record the marked unqualified points in the marked data, and check whether all unqualified points are marked, if not, according to the distribution map and the marked data The data is flagged for unflagged failure points. Make sure that every non-conforming point is marked.

[0041] As preferably, the method also includes before step B:

[0042] Step A: Take pictures of the circuit board to generate a test picture, and automatically analyze the test picture to determine whether there are unqualified points on the circuit board, a...

Embodiment 3

[0044] According to another embodiment of the present invention, a device for marking test results of circuit boards is provided, see image 3 , including: a main controller, a position sensor, a mechanical arm, and a marking pen; the marking pen is set on the mechanical arm; the main controller can be an MCU.

[0045]The main controller is connected with external circuit board testing equipment for data. The circuit board testing equipment can be X-RAY equipment or AOI optical testing equipment. The main controller judges the circuit being transported according to the circuit board test results detected by the circuit board testing equipment. Whether the board is qualified, and control the position sensor to detect whether the unqualified circuit board delivered to the SMT connecting station (controlled by PLC) reaches the predetermined position. When the circuit board reaches the predetermined position, stop the circuit board detection equipment to convey the circuit board A...

Abstract

The invention relates to the field of marking, and particularly relates to a method, equipment and a system for marking a test result of a circuit board. The method comprises the steps of: determiningwhether conveyed circuit boards are qualified or not according to a detected circuit board test result; detecting whether an unqualified circuit board in the conveying process reaches a preset position or not; stopping conveying the circuit board when the circuit board reaches the preset position; generating a distribution diagram of unqualified points on the circuit board according to a test result of the circuit board; and carrying out unqualified point marking on corresponding positions on the circuit board according to the distribution diagram. The method, the equipment and the system avoid radiation damage to marking personnel caused by circuit board detection equipment in the existing marking, facilitate next maintenance for the maintenance engineers after the unqualified circuit board is marked, achieve automatic operation, are high in efficiency, replaces the personnel with machines, finish the marking operation by means of the machines completely, protect the personnel against radiation influences, and avoid the situation of marking missing.

Description

technical field [0001] The invention relates to the field of marking, in particular to a method, device and system for marking test results of circuit boards. Background technique [0002] After the factory performs FPC SMT placement, it is necessary to use x-ray inspection equipment to take pictures of the FPC to confirm that it is not welded or missing parts. , resulting in noise or distortion when the device collects sound signals. [0003] Limited by the site, for the x-ray test results, the operator needs to visually observe the shooting results next to the x-ray equipment to judge whether the FPC product is OK. After the FPC product carrier board is sent out by the x-ray equipment, use a marker Make a mark to facilitate maintenance personnel to carry out maintenance. Since x-ray radiation is extremely harmful to humans, it is not advisable for people to stay next to x-ray equipment for a long time. X-ray radiation will cause harm to human body for a long time. Cont...
