Abstract

The invention discloses a non-contact image detection device. The device comprises an image acquisition device and a worktable. The worktable comprises a carrier belt conveying rail, a camera control rail is arranged above the carrier belt conveying rail in parallel, and the two ends of the camera control rail are fixed to lifting control devices. The image acquisition device comprises a CCD camera, a camera control device, a signal processing device and a main controller which are sequentially connected, the main controller is connected with a display device, and the CCD camera is arranged on the camera control rail and provided with an electrostatic protection device which can avoid influences of static electricity on the CCD camera.

Description

technical field [0001] The invention relates to the field of carrier tape detection devices, in particular to a non-contact image detection device. Background technique [0002] Holes for holding electronic components and positioning holes for index positioning are equidistantly distributed in the length direction of the carrier tape. In the production process of the carrier tape, there are generally two ways to control the quality of the carrier tape: manual inspection and machine inspection. The former uses manual inspection of the shape of the product on the production line, which has low inspection efficiency and unstable inspection results; the latter usually uses image inspection. The device detects the shape of the products on the production line. This method has high detection efficiency and stable detection effect. Currently, existing image detection devices generally use a CCD camera to collect images. When collecting the image of the carrier tape, static electri...
