Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
It is described in the utility model a kind of with assisted focused and collision prevention function microscope, bag as shown in Fig. 1~Fig. 2
Include support base 1 and the eyepiece component 2 arranged on support base 1, objective lens unit 3, focus adjusting mechanism 4 and objective table 5, focus adjusting mechanism 4 with
Objective table 5 is sequentially connected, and is lifted to driving objective table 5, further includes security plane, movement portion 6, displacement sensor 7, controller
100 and alarm 8, wherein, security plane is a virtual plane, is not higher than the minimum point of objective lens unit 3, movement portion 6
Arranged on support base 1 and objective table 5 is connected to, movement portion 6 can be transported with 5 synchronization lifting of objective table, displacement sensor 7 to detect
The move distance in dynamic portion 6, and the move distance is converted into electric signal, controller 100 receives the telecommunications that displacement sensor 7 exports
Number, judge whether the distance between objective table 5 and security plane are less than safe distance according to electric signal, if being less than, to alarm
Device 8 sends instruction, and alarm 8, which receives, to be instructed and send a warning.Since security plane is minimum not higher than objective lens unit 3
Point, so, in theory, as long as objective table 5 is not higher than security plane, objective table 5 would not bump against with objective lens unit 3.At this
In embodiment, the move distance in movement portion 6 is converted to voltage value by displacement sensor 7, and with 5 lifting height of objective table
Increase, the voltage value increase that displacement sensor 7 exports, when the height of objective table 5 and the identical height of security plane, displacement passes
Sensor 7 can export a voltage value V1, when the height of objective table 5 differs the value that numerical value is safe distance with the height of security plane
When, displacement sensor 7 can export a voltage value V2, therefore, when the voltage value that displacement sensor 7 can export is less than V2, then
Representing that the distance between objective table 5 and security plane are more than safe distance, objective table 5 will not bump against with objective lens unit 3 easily,
When the voltage value that displacement sensor 7 can export between vl and v 2 when, then it represents that the distance of objective table 5 and security plane is less than peace
Full distance, objective table 5 easily bump against with objective lens unit 3, also, when the voltage value that displacement sensor 7 exports is more than V2, report
Alert device 8 sends a warning, and staff is reminded to operate with caution, is bumped against to prevent objective table 5 and objective lens unit 3.Certainly, easily
It is contemplated that the present embodiment can be designed as, the voltage value exported with the increase of 5 lifting height of objective table, displacement sensor 7
Reduce, the judgement of distance value between objective table 5 and security plane, detailed process can be still realized according to above-mentioned identical principle
It repeats no more.Meanwhile it is also readily appreciated that, the other kinds of electric signal that displacement sensor 7 can also export, such as current value
Deng.Meanwhile safe distance can be set according to actual demand, and in the present embodiment, safe distance 1mm.
