Example Embodiment

[0029] In order to achieve the above purpose, figure 1 It is a hardware topology diagram showing a device for identifying and detecting the stacking sequence of PCB boards in a conventional hot-melt board forming process.

[0030] The hardware of the equipment to identify and detect the stacking sequence of PCB boards consists of a digital camera, an industrial computer that processes images and IO logic, a cylinder that controls the lifting of the camera, a remote IO module that interacts with the equipment PLC and the signal of the cylinder solenoid valve, solenoid valve, and material detection. It consists of sensors, relays and related mechanical fixing and adjustment components.

[0031] The digital camera adopts an ordinary industrial camera, which is different from an industrial smart camera. It only collects images without processing. The processing is done by software, which can realize more flexible and complex arithmetic processing. It is used to collect image data ...

Abstract

The method belongs to computer vision, software engineering and video image processing, and can automatically identify the serial numbers of the boards in PCB lamination hot melting through video images acquired by a camera, so that stacking according to a set sequence is ensured, and wrong stacking is prevented. The invention discloses a system for preventing stacking faults in PCB (Printed Circuit Board) lamination hot melting. The system is characterized by comprising a video image acquisition system, a data processing system and a detection alarm system, the video image acquisition system comprises a CCD (Charge Coupled Device) digital camera, acquires a dynamic video image of a plate placed in PCB lamination hot melting from the camera in real time through a bus, and transmits the video image to the data processing system; the data processing system is responsible for processing video data, comparing an identification result with a set plate stacking sequence, identifying errors such as repeated plate placement, wrong plate placement, less placement/more placement and the like, and sending a comparison result to the detection alarm system; the detection alarm system gives an alarm sound and blocks an equipment processing command when a stacking error occurs, and ensures the normal operation of the processing equipment when the stacking error is correct; a machine vision motion detection method is creatively used for identifying the manual board placing process, and a new solution is provided for the board placing process which is not suitable for being detected by a common sensor.

Description

technical field [0001] The invention belongs to computer vision, software engineering, and video image processing. The video image obtained by the camera can automatically identify the number of the plates in the PCB lamination hot-melt, ensure that they are stacked according to the set order, and can identify repeated board placement and wrong board placement. , less / more errors, etc., to prevent stacking faults in the circuit board production process. The present invention relates to an error proofing system, in particular to a computer vision-based system for preventing stacking faults in PCB lamination hot-melt. Background technique [0002] PCB circuit board, also known as printed circuit board, is an important electronic component, a support body for electronic components, and a carrier for electrical interconnection of electronic components. Its design is mainly layout design. The main advantage of using circuit boards is to greatly reduce wiring and assembly errors,...
