This utility model discloses a novel SMT placement equipment, comprising: a placement equipment body, through which the working status of the placement equipment body can be observed via an arc-shaped observation window on a protective cover; a motor on the protective cover rotates a lead screw to move an LED light within the protective cover, providing more precise illumination and ensuring that the area observed within the observation window is illuminated; simultaneously, the extension and retraction of a pneumatic telescopic rod allows the LED light to be adjusted in angle, achieving optimal lighting effects and providing a better user experience; when the inner side of the arc-shaped observation window fogs up or becomes dusty, the pneumatic telescopic rod can be extended and retracted to bring a cleaning wipe into contact with the inner side of the arc-shaped observation window; the cleaning wipe is then moved along with the movement of a fixed frame to wipe the inner side of the arc-shaped observation window, providing a clearer and higher visual quality; after wiping, the cleaning wipe is retracted to prevent it from continuously rubbing against the observation window while the fixed frame is moving.

The utility model belongs to the field of medical apparatus and instruments especially, it is a kind of analytical equipment of evaluating YAG treatment MIOL after the analysis device of visual effect of visual impairment, it includes the measuring table for evaluating YAG treatment MIOL after the measuring table of visual effect of visual impairment, the top of measuring table is slidably installed with measuring equipment main part, the side of measuring equipment main part is equipped with lifting groove;The inside of lifting groove is slidably installed with sliding block, the side of sliding block is fixedly installed with moving column, the moving column is equipped with universal mechanism, the side of universal mechanism is equipped with lighting light source, the top of measuring table is fixedly installed with head fixer. The utility model can adjust the angle of lighting light source, so that it can more accurately illuminate the eye of patient when measuring, no longer need medical staff to manually adjust several times, greatly improve the measuring efficiency, increase the practicability of equipment and the accuracy when measuring.

The utility model relates to the technical field of detection, and particularly discloses a cigarette carton appearance detection device based on machine vision, which comprises a separation device, a detection device, a control cabinet, a rejection device and a conveying belt, a human-computer interface is installed on the support between the separating device and the detecting device, the removing device is installed on the right side of the detecting device, and the control cabinet is installed below the conveying belt. The device is reasonable in design and convenient to install, the two servo motors are used for controlling the synchronous belt to operate in the opposite directions, the Ethernet color camera is used for being matched with the arched white lighting structure to image cigarette strips, and meanwhile the quality of the cigarette strips is improved. The short strip-shaped light source irradiates the two end faces of the cigarette strip at an angle of 45 degrees, so that the appearance of the cigarette strip is efficiently and accurately detected, and the production quality and efficiency are improved.
