Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 and 2, a visual inspection apparatus for an LED lamp on an FPCA may include a test platform (not shown) and a test fixture 1, a dc power supply 2, a test driving board 3, and an LED lamp visual inspection machine mounted on the test platform. Wherein, the test fixture 1 is used for clamping the FPCA to be tested and has a structure. The test driving board 3 with binding post electricity on the test fixture 1 is connected for drive the last LED lamp of FPCA, DC power supply is used for the test driving board power supply, and then lights the last LED lamp of FPCA. The LED lamp visual inspection machine comprises a camera, a host and a display 5. The camera is installed 1 top of test fixture, with the host computer electricity is connected for shoot the LED lamp image on the FPCA, the host computer is used for according to predetermineeing the procedure to the LED lamp image on the FPCA that the camera was shot handles. Preferably, the camera and the host are an integrated smart camera 4 to save space. The display 5 is electrically connected with the host and used for displaying the test result.

Because the FPCA of different specifications, LED lamp position on it is different, consequently, in order to ensure that the camera can shoot the LED lamp, need adjust the position of camera or test fixture for the LED lamp on the FPCA that awaits measuring is located the shooting range of camera. Specifically, the camera is mounted on an adjustable support, or the test fixture is movably positioned below the camera. Preferably, the adjustable bracket is a manual adjustment bracket capable of adjusting the front and back, left and right, and up and down positions, so as to conveniently adjust the position of the camera.

In an embodiment, a start switch is disposed on the test driving board 3, and the start switch is used for triggering visual detection. When a starting switch ON the driving test board 3 is toggled to an ON gear, an LED lamp ON the FPCA is lightened, and meanwhile, a camera is triggered to automatically shoot, and then a test result is displayed ON a display.

The working process of the present invention is briefly described as follows: after the test fixture, the drive test board, the direct-current power supply and the LED visual inspection machine are connected, placing the test fixture on a test table; placing the FPCA to be tested ON a test fixture lightly, pressing down a quick clamp of the fixture, and then toggling a starting switch ON a driving test board to an ON gear, wherein at the moment, all LED lamps are lightened; at the moment, the LED visual inspection machine inspects the appearance and the performance of the LED lamp through a preset program and outputs a test result on the display, if the LED lamp is good, green OK is displayed, and if the LED lamp is not good, red NG is displayed. The whole test result is simple and clear, the outflow of defective products is avoided, the labor intensity of workers is greatly reduced, and the working efficiency is improved.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
