Abstract

The utility model discloses an automatic optical intelligent detecting system. The system comprises a shell, a scanner, a PCB (Printed Circuit Board) placing frame, a conveying device, a controller and a display screen, wherein the scanner is fixedly arranged in the shell; the conveying device can be used for driving the PCB placing frame to move in a linear reciprocating way so as to enter and exit an imaging range of the scanner; the scanner can be used for transmitting an imaging graphic signal to the controller; and the controller is used for comparing a scanned image and a set image and displaying a distinguishing position image on the display screen; according to the utility model, images are obtained by the scanner; only through driving the PCB placing frame to linearly move through the conveying device, a PCB to be detected can be sent below the scanner to be scanned; the automatic optical intelligent detecting system disclosed by the utility model has the advantages of simple integral structure, high detecting speed, high image definition and high detecting accuracy; moreover, the controller can be used for saving a whole image obtained by scanning, thereby being convenient for filing and checking.

Description

The automated optical intelligent checking system

Technical field

The utility model relates to a kind of PCB checkout equipment, particularly a kind of automated optical intelligent checking system.

Background technology

Present various electronic product is increasingly extensive, and market is huge, and electron device is more and more littler; Degree of integration is increasingly high, from the control of cost and quality, and all can be more and more stricter to each production link of electronic product; The detection of PCB wiring board is one of test job, the machine that also has some to detect the PCB circuit now, but these machine great majority are to detect the circuit board that components and parts are arranged; The circuit board size that can detect is less, obtains the mode of image and obtains through camera, in obtaining the process of image, wants dollying head or circuit board to do moving of direction all around; Use inconvenience, accuracy of detection is lower.

The utility model content

In order to overcome above-mentioned defective, the utility model provides a kind of automated optical intelligent checking system, and this automated optical intelligent checking system is simple in structure, detection speed is fast, accuracy of detection is high, easy to use.

The utility model for the technical scheme that solves its technical matters and adopt is: a kind of automated optical intelligent checking system; Comprise casing, scanner, PCB rack, transport, controller and display screen; Scanner is fixedly arranged in the casing, and transport can drive the straight reciprocating motion of PCB rack and then entering and withdraw from the imaging scope of scanner, and scanner can be transferred to controller with the imaging figure signal; Controller will scan drawing and set drawing and compare and will distinguish the position image and on display screen, show; During use, pcb board is placed on the PCB rack, transport drives the image space that the PCB rack is linearly moved to scanner; Obtain PCB circuit board drawing picture and send controller to through scanner; Controller compares image and the standard form that is provided with in advance, finds out and the defect point of the different place of standard form as wiring board, is presented on the display and preserves the positional information of defect point.

Further improvement as the utility model; The structure that said transport can drive the straight reciprocating motion of PCB rack and then entering and withdraw from the surface sweeping scope of scanner is: transport comprises motor, first and second power wheel and driving-belt; First and second power wheel can rotational positioning in casing; Driving-belt closely is sheathed on first and second power wheel outside, and motor is fixedly arranged in the casing, the rotation of motor-driven first power wheel; The PCB rack is fixedly arranged on driving-belt top, under driving-belt just is positioned at the sweep limit of scanner along an end of its direction of motion.

As the further improvement of the utility model, said first and second power wheel periphery is provided with engaging tooth, and driving-belt is the belt of inboard band engaging tooth, can certainly be through sprocket wheel and chain drive.

As the further improvement of the utility model, said controller is a host computer.

As the further improvement of the utility model, said casing is provided with an import with inside and outside connection, and the PCB rack can reach the casing outside from this import.

As the further improvement of the utility model, also be provided with guide rail in the casing, the PCB rack is sheathed on the guide rail outside, and guide rail has guide effect to the PCB rack, guarantees its kinematic accuracy.

The beneficial effect of the utility model is: the utility model is to obtain image through scanner; Only need transport to drive the PCB rack and do straight line and move and scan below just can PCB to be checked being sent to scanner, its one-piece construction is simple, and detection speed is fast; The drawing sharpness is high; Accuracy of detection is high, and controller can preserve one whole image that scanning obtains, and is convenient to file and the inspection needs.
