Problems solved by technology
In order to be able to collect clear images, the objective lens of the microscope needs to move up and down relative to the specimen to be tested to focus. The existing objective lens is usually set so that the specimen is fixed when moving relative to the specimen, and the objective lens is controlled by the driving device to move up and down. It is set as a rack and pinion structure, and its control accuracy is limited, so it is impossible to realize the rapid movement of the objective lens or the accurate displacement of the image

The present application discloses an objective lens driving device, which includes a mounting column, a driving component, and a screw transmission component. The screw transmission component includes a screw, a first nut, and a second nut, and the first nut is fixedly connected to the mounting column. The second nut is fixedly connected with the objective lens, and the second nut moves axially along the mounting column, and the screw rod is provided with two sections of threads in turn, the first thread and the second thread, and the screw rod is provided with two sections of threads. The end of the first thread far away from the second thread is connected to the driving part, the first thread and the first nut form a first screw pair, and the second thread and the second nut form a second screw pair. The screw pair, the objective lens driving device of the present invention has a simple structure and high precision, and realizes precise adjustment of the upper and lower positions of the objective lens; the present invention also provides a microscope using the above objective lens driving device.
Description
technical field [0001] The present application relates to the technical field of optical instruments, in particular to an objective lens driving device and a microscope. Background technique [0002] A microscope is composed of one or more lens combinations, and is mainly used to magnify tiny objects, making it an instrument that can be observed by human eyes. Among them, biological microscopes are often used to observe and study biological slices, biological cells, bacteria, living tissue culture, and fluid precipitation. Such as blood routine analysis, urine microscopic analysis and so on. [0003] With the improvement of the degree of automation, a digital camera device is added to the microscope for the microscope analysis instrument. In order to be able to collect clear images, the objective lens of the microscope needs to move up and down relative to the specimen to be tested to focus. The existing objective lens is usually set so that the specimen is fixed when movi...
