Problems solved by technology

As in the prior art, in the face of the detection of large-area DUTs, such as FPD boards, etc., the current solution is to use multiple CCD cameras in a line, which obviously causes a significant increase in cost; another solution is to use a single Camera plus drag chain realizes reciprocating motion for image scanning detection. This method requires too high speed of reciprocating motion; Unable to ensure high positioning accuracy, also resulting in a reduction in detection accuracy

Abstract

The invention discloses an optical detection device and detection equipment using the device. The device includes a main detection camera component, a re-inspection camera component, a positioning camera component, a line scanning drive component, a drag chain component and a double-cavity box frame; the detection device includes A vibration-absorbing stand, a platform module, and an optical detection device, wherein the platform module and the optical detection device are arranged on the shock-absorbing stand. The positioning, initial inspection and re-inspection of DUTs of different specifications are realized through the main inspection camera assembly, re-inspection camera assembly, and positioning camera assembly. Two sets of main inspection camera assemblies are used to replace the existing multiple sets of line-row camera groups, reducing the cost. cost, re-inspection after the initial inspection improves the detection accuracy and detection efficiency, and realizes the feeding positioning and defect position positioning of different specifications of the parts to be tested by positioning the camera, which improves the functional integration and detection efficiency of the whole machine and reduces the cost of inspection. Machine cost and failure rate.

Description

technical field [0001] The invention relates to detection equipment and its parts technology, in particular to an optical detection device and detection equipment using the device. Background technique [0002] Indispensable for testing equipment for motherboards of 3C products such as computer-computer, communication-communication, consumer electronics-consumerelectronics (such as FPC, flexible printed circuit, flexible printed circuit board, FPD, flat panel display-flat panel display) It is used for the vision or image inspection mechanism of the DUT, which is usually used in conjunction with the transfer device to detect defects and / or measure the size of the DUT. [0003] However, with the increasingly higher precision and multi-functional integration requirements of inspection equipment, inspection equipment has more and more functional requirements for visual or image inspection mechanisms. As in the prior art, in the face of the detection of large-area DUTs, such as ...
