Description

Technical Field

[0001] This utility model relates to the field of microscope technology, specifically to a precision electric sample carrier platform that is easy to fix. Background Technology

[0002] Currently available microscope platforms have certain limitations: their sample placement area is relatively small, limiting the number of samples they can accommodate, which in turn restricts their range of motion. Regarding motorized platforms, most products lack sufficient movement precision and generally employ open-loop stepper motors combined with optocoupler switches for limit functions, or rely on a closed-loop control system within the motor paired with optocoupler switches for limit control.

[0003] In terms of motor-driven motion, common types include lead screw and nut, synchronous belt, and linear drive, with the lead screw and nut method offering relatively higher precision. However, the closed-loop control within the motor cannot effectively eliminate errors caused by factors such as backlash in external mechanisms, leading to a discrepancy between control precision and the actual positional precision of the platform. Furthermore, the sample placement and fixing methods are relatively complex and inconvenient to operate.

[0004] Based on this, the present invention designs a precision electric loading platform that is easy to fix samples in order to solve the above problems. Utility Model Content

Then, the clamp slider 19 is pulled forward along the movable groove 20. During the movement, the clamp slider 19 will also compress the compression spring 21 until the locking pin 22 is aligned with the front locking hole 24. At this time, the compression spring 23 will reset and drive the locking pin 22 to be inserted into the front locking hole 24. At this time, the operator can put the sample to be observed into the sample placement groove 3, and then pull the locking pin 22 out of the front locking hole 24. Under the reset action of the compression spring 21, the clamp slider 19 will reset backward and press against the sample, so that the sample is pressed against the inner wall of the sample placement groove 3, thereby fixing the sample in the sample placement groove 3. The sample can then be observed through a microscope. During the observation, the X-axis linear stepper motor 4 drives the X-axis drive screw 25 to rotate, which causes the X-axis backlash-free nut 2 to drive the X-axis moving plate 12 to move left or right along the Y-axis cross roller guide 13. During the movement, the X-axis reading head 17 cooperates with the X-axis grating ruler 18 to continuously monitor the movement distance of the X-axis moving plate 12. Furthermore, the Y-axis linear stepper motor 5 drives the Y-axis drive screw 26 to rotate, causing the Y-axis backlash-free nut 8 to drive the Y-axis moving plate 15 to move forward or backward along the Y-axis cross roller guide 13. During the movement, the Y-axis grating ruler 7 and the Y-axis grating ruler 7 work together to continuously monitor the movement distance of the Y-axis moving plate 15. By cooperating with the X-axis linear stepper motor 4, the Y-axis linear stepper motor 5, the Y-axis grating ruler 7, the X-axis reading head 17, the X-axis backlash elimination nut 2, and the Y-axis backlash elimination nut 8, the mechanical backlash is reduced, the control accuracy of the device on the actual position of the sample is improved, the applicable range is increased, and the travel of the X-axis and Y-axis is increased.
