Description

TECHNICAL FIELD

[0001] The utility model relates to test equipment technical field especially, relate to a camera definition detection and foreign matter detection one drags two equipment. BACKGROUND

[0002] The definition detection of camera is generally that manual places the camera to be detected on the detection fixture, drives by the cylinder, drives the camera to move to the detection position, and the detection position is equipped with relay lens optical system, and the image of camera shooting standard definition test card is passed through the optical transmission of relay lens. After the host computer receives the image, the line bundle definition on the definition test card is analyzed, and the imaging quality of the camera is judged based on the preset standard, and the definition detection is completed.

[0003] The camera focusing detection adopts the same equipment as the definition detection, when the fixture reaches the detection position, the operator manually rotates the camera lens, and simultaneously observes the definition value displayed by the host computer. The image reaches the best definition by manually adjusting the lens position, and the host computer judges whether the focusing is qualified according to the set definition threshold, so that the focusing detection of the camera is realized.

[0004] The camera foreign matter detection also manually places the camera to be detected on the detection fixture, and the detection position is equipped with a white backlight plate and a uniform light source. After the camera shoots the lamp plate image, the host computer analyzes the image, identifies whether there is dust, fiber or oil stain and other foreign matters, and based on the preset foreign matter judgment standard, the system outputs the detection result, and the foreign matter detection of the camera is completed.

[0005] The camera definition detection and foreign matter detection are not in the same station, and two stations are tested respectively, and it takes about 30 seconds and 25 seconds respectively. The definition detection equipment is usually one-to-one, that is, a single device can only detect one device at the same time, and the detection efficiency is low. The foreign matter detection equipment is usually non-standard, and the equipment form is not unified. The foreign matter detection equipment currently has two forms, that is, the fixture is manually pushed or the cylinder automatically tests (the fixture moves or the foreign matter detection lamp plate moves). Part of the foreign matter detection of the product is placed on the camera whole machine detection equipment (which is the last process of camera product test, and the whole camera product is tested), so that the detection time of a single camera whole machine detection equipment increases by 40 seconds. If the product has foreign matter, the time of the previous process is wasted, the rework is complicated, the detection efficiency is low, the whole machine detection line body pass rate is reduced. Therefore, the existing camera definition and foreign matter detection equipment cannot meet the production demand of high productivity and high yield. UTILITY MODEL CONTENTS

Then the X-axis transplanting assembly of the other set of foreign matter detection modules is controlled to drive the test fixture assembly to move to the lower side of the relay lens assembly to perform detection, and the detection method is the same as above.

[0030] If it is judged in the early stage that the foreign matter detection of the two to-be-detected cameras is qualified only once, the to-be-detected camera with qualified foreign matter detection is controlled to perform clarity detection, the to-be-detected camera with unqualified foreign matter detection is directly placed in the unqualified product box, if it is judged in the early stage that the foreign matter detection of the two to-be-detected cameras is not qualified, the two to-be-detected cameras are directly placed in the unqualified product box and clarity detection is not performed, so that the detection efficiency is further improved.
