[0002] As a kind of measuring instrument, microscope is often used to measure the surface micro three-dimensional topography of an object. In specific use, the imaging focus of the object in the objective lens is usually adjusted by adjusting the height of the lifting lens barrel, so as to observe the micro topography of the object.

[0003] The existing microscope generally has a coarse focusing screw for coarsely adjusting the distance between the objective lens and the object and a fine focusing screw for finely adjusting the distance between the objective lens and the object, which are arranged at different positions of the body of the microscope. When using the microscope for observation, the user usually rotates the coarse focusing screw to coarsely adjust the distance between the objective lens and the object, and then rotates the fine focusing screw to finely adjust the distance between the objective lens and the object when the distance between the objective lens and the object is relatively small.

[0004] In addition, a multifunctional button is disclosed in a Chinese patent with the publication number CN208902263U and the patent name "Spectrophotometer with multifunctional button".

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. In the following description, identical components are assigned identical reference numerals, and duplicate descriptions are omitted. In addition, the accompanying drawings are merely schematic, and the proportions of the dimensions of the components and the shapes of the components may differ from the actual ones.

[0033] Figure 1 2 is a schematic diagram showing the overall structure of the multi-function button involved in the embodiment of the present disclosure. Figure 2 is a cross-sectional view showing a multi-function button according to an embodiment of the present disclosure.

[0034] Reference Figure 1 and Figure 2 The multi-function button 10 (hereinafter sometimes referred to as the button 10) involved in this embodiment can be a multi-function button provided on a measuring instrument. The multi-function button 10 can be provided on a base or body of the measuring instrument. The multi-function button 10 can include a conversion mechanism 120, a steering sleeve, a rotary encoder 140, and a fixing member 150.

[0035] In some examples, the measuring instrument can be a microscope, a vision tester, a spectrophotometer, or the like. In the present embodiment, the measuring instrument can be a microscope (or a confocal microscope) as shown in FIG. 1, and the following description is made with the microscope as an example. Figure 4

[0036] Specifically, the fixing member 150 can be arranged around the steering sleeve and fixed to the housing (base or body) of the measuring instrument, and the conversion mechanism 120 can be arranged in the steering sleeve in a rotatable and movable manner. One end of the rotary encoder 140 can be fixedly connected to the conversion mechanism 120 through the shaft hole of the conversion mechanism 120, and the other end of the rotary encoder 140 can be connected to the switch circuit 7. At least one of the rotation direction, displacement distance, and displacement times of the conversion mechanism 120 can be changed to control the rotary encoder 140 to trigger the switch circuit 7 and output control signals of different sizes and directions to the main control board 2.

[0037] In the present disclosure, by controlling the rotation direction of the conversion mechanism 120 and its displacement and displacement times in the fixing member 150, the rotary encoder 140 can be controlled to trigger the switch circuit 7 and output control signals of different sizes and directions to the main control board 2. In this case, different control signals emitted by the button 1 in different action modes can be used to trigger different functions of the microscope.

[0038] In some examples, the button 1 can further include a screw 160 screwed with the conversion mechanism 120 and an outer cap 110 clamped with the screw 160. The outer cap 110 can be moved to displace the conversion mechanism 120 relative to the fixing member 150. At this time, the screw 160 can be screwed with the conversion mechanism 120. In this case, the outer cap 110 and the conversion mechanism 120 can be fixedly connected, and the fixing member 150 can increase the torque of the rotation of the outer cap 110 to facilitate the rotation, and can also support and guide the rotation of the outer cap 110.

[0039] In some examples, the outer cap 110 can be rotated clockwise or counterclockwise on the surface of the fixing member 150. The forward and reverse (clockwise and counterclockwise) rotation of the outer cap 110 can adjust the increment or decrement of the corresponding function, for example, the up or down of the lifting mechanism, or the bright or dark of the illumination light source can be adjusted by the forward and reverse rotation of the outer cap.

[0040] ​In some examples, the displaceable distance of the conversion mechanism 120 relative to the fixed part 150 can be 0.5-1.5mm, which can be achieved by moving (pressing) the outer cap 110 to drive the conversion mechanism 120 to displace relative to the fixed part 150. In this way, the displacement of the conversion mechanism 120 relative to the fixed part 150 can be conveniently controlled, and thus the rotation encoder 140 can be controlled to trigger the switch circuit 7 to output control signals of different sizes and directions.

[0041] In some examples, more preferably, the displaceable distance of the conversion mechanism 120 relative to the fixed part 150 can be 1mm.

[0042] In some examples, the conversion mechanism 120 can be driven to displace inwardly by 1mm by single-clicking the outer cap 110, so as to control the rotation encoder 140 to trigger the switch circuit 7 to output a first control signal; then, the outer cap 110 can be reset (i.e. displace outwardly by 1mm) to trigger the switch circuit 7 to output a second control signal.

[0043] In some examples, the first control signal can have a strength greater than that of the second control signal. In other examples, the second control signal can also be set to have a strength greater than that of the first control signal.

[0044] In some examples, the conversion mechanism 120 can be driven to displace inwardly by 1mm by double-clicking the outer cap 110, so as to trigger the switch circuit 7 to output a third control signal.

[0045] In some examples, the third control signal can have a strength less than that of the first control signal and the second control signal.

[0046] In some examples, the first control signal, the second control signal and the third control signal can also be set to different signal modes.

[0047] In some examples, the control signal can include a level signal triggered by the action (displacement and displacement times) of the conversion mechanism 120 and a rotation pulse signal triggered by the rotation of the conversion mechanism 120.

[0048] In some examples, the switch circuit 7 can be triggered to output level signals of different sizes by the movement of the rotation encoder 140.

[0049] In some examples, the outer surface of the fixed part 150 can be uniformly provided with damping grooves 151 for adding damping oil, and the fixed part 150 can be provided as a hollow structure. In this way, the outer cap 110 can be conveniently rotated on the surface of the fixed part 150, and the hollow structure of the fixed part 150 can reduce its own weight without affecting its supporting and guiding functions, thereby improving the user's operation feeling.

[0050] In some examples, the damping groove 151 can be arranged as an annular groove around the fixing member 150. In some examples, the number of annular grooves can be 1, 2, 3, 4, 5, 6, etc.

[0051] In some examples, the outer rotary cap 110, the screw 160, the conversion mechanism 120, the steering sleeve, and the fixing member 150 can be arranged as a rotational axis symmetrical structure.

[0052] In some examples, the outer rotary cap 110, the screw 160, the conversion mechanism 120, the steering sleeve, and the fixing member 150 can be coaxially arranged around the central axis of the outer rotary cap 110. In this way, the symmetry of the multifunctional button 1 structure can be formed, and the aesthetic appearance and operability of the multifunctional button 1 structure can be enhanced.

[0053] Figure 3 FIG. 1 is a structural schematic diagram of a microbead sleeve according to an embodiment of the present disclosure.

[0054] Referring to Figure 3 In some examples, the steering sleeve can be a microbead sleeve 130.

[0055] In some examples, a plurality of balls can be uniformly arranged on the microbead sleeve 1, and the conversion mechanism 120 and the fixing member 150 can be pre-pressed and attached to the balls on the microbead sleeve 1 to realize an interference fit between the conversion mechanism 120, the fixing member 150, and the microbead sleeve 1. The microbead sleeve 1 can move axially and rotate radially between the conversion mechanism 120 and the fixing member 150 through the balls arranged thereon. In this way, the microbead sleeve 1 can facilitate high-precision operation or movement of the outer rotary cap 110 and the conversion mechanism 120.

[0056] In some examples, the rotation of the conversion mechanism 120 can drive the rotation of the rotary encoder 140, and the movement of the conversion mechanism 120 can drive the movement of the rotary encoder 140. In this way, the rotary encoder 140 can be triggered to output a control signal, which can include a level signal and a rotation pulse signal.

[0057] In some examples, a reset spring and a clamping member can be arranged at the contact surface of one end of the rotary encoder 140 and the conversion mechanism 120. When the conversion mechanism 120 is displaced inward, the clamping member can be clamped and then rotated. When a reset is desired, the outer rotary cap 110 can be pressed again to easily reset the conversion mechanism 120 under the action of the reset spring.

[0058] In other examples, the reset mode can also be manual dragging reset.

[0059] Figure 4 FIG. 1 is a functional module diagram of a microscope according to an embodiment of the present disclosure.Figure 5 is a schematic diagram showing the overall structure of a microscope involved in the embodiments of the present disclosure. Figure 6 is a control module diagram of a microscope involved in the embodiments of the present disclosure.

[0060] With reference to Figure 4 and Figure 5 , the present disclosure also provides a microscope, which can include the multifunctional button 1 as described above and a switch circuit 7, a main control board 2, a motor 3, a dimming control assembly 4, a lifting mechanism 5 and an illumination light source 6. One end of the switch circuit 7 is connected to the other end of the rotary encoder 140, and the other end of the switch circuit 7 is connected to the input end of the main control board 2. The first output end of the main control board 2 is connected to the input end of the motor 3, and the output end of the motor 3 can be connected to the lifting mechanism 5. The second output end of the main control board 2 can be connected to the input end of the dimming control assembly 6, and the output end of the dimming control assembly 6 can be connected to the illumination light source 6.

[0061] In the present disclosure, the main control board 2 can receive and identify different sizes and directions of control signals triggered by the multifunctional button 1, and then trigger the motor 3 or the dimming control assembly 4 to work according to different control signals, so that the motor 3 or the dimming control assembly 4 can control the corresponding control lifting mechanism 5 or illumination light source 6 to work.

[0062] In some examples, when the button 1 is in the initial state, the outer layer of the rotating cap 110 can be controlled to trigger the rotary encoder 140 to output a second control signal to the switch circuit 7, and the main control board 2 receives and identifies the second control signal to control the motor 3 to rotate at a second speed, thereby controlling the lifting mechanism 5 to ascend or descend. The outer layer of the rotating cap 110 can be rotated in forward or reverse direction to control the lifting mechanism 5 to ascend or descend.

[0063] In some examples, the outer layer of the rotating cap 110 can be clicked to control the rotary encoder 140 to trigger the switch circuit 7 to output a first control signal, and the main control board 2 receives and identifies the first control signal to control the motor 3 to rotate at a first speed, thereby controlling the lifting mechanism 5 to ascend or descend at the first speed. The outer layer of the rotating cap 110 can be rotated in forward or reverse direction to control the lifting mechanism 5 to ascend or descend.

[0064] In some examples, the outer layer of the rotating cap 110 can be double-clicked to control the rotary encoder 140 to trigger the switch circuit 7 to output a third control signal, and the main control board 2 receives and identifies the third control signal to control the dimming control assembly 4 to output a corresponding dimming control signal, thereby controlling the brightness of the illumination light source 6. The outer layer of the rotating cap 110 can be rotated in forward or reverse direction to control the illumination light source 6 to brighten or darken.

[0065] In some examples, the control signals can include level signals and rotation pulse signals, i.e., the first control signal can include a first level signal and a first rotation pulse signal, the second control signal can include a second level signal and a second rotation pulse signal, and the third control signal can include a third level signal and a third rotation pulse signal.

[0066] In some examples, the first level signal can be different from the second level signal. In some examples, the first level signal can be a level signal output by the switch circuit 7 triggered by one rotation of the rotary encoder 140, and the second level signal can be a level signal output by the switch circuit 7 triggered after the rotary encoder 140 is reset.

[0067] In some examples, the level signal output by the switch circuit 7 triggered by one rotation of the rotary encoder 140 can be a low level signal, and the level signal output by the switch circuit 7 after the rotary encoder 140 is reset can be a high level signal.

[0068] In some examples, the main control board 2 can output a first driving signal to drive the motor 3 to rotate fast by recognizing the first level signal and the first rotation pulse signal, and output the first driving signal to drive the motor 3 to rotate slowly by recognizing the second level signal and the second rotation pulse signal. In this case, the motor 3 can be controlled to rotate fast by the first level signal and the first rotation pulse signal, and the lifting mechanism 5 can be controlled to lift fast, and the motor 3 can be controlled to rotate slowly by the second level signal and the second rotation pulse signal, and the lifting mechanism 5 can be controlled to lift slowly.

[0069] In some examples, the third level signal can be different from the first level signal and the second level signal. In some examples, the main control board 2 can recognize two level signal changes output by the switch circuit 7 triggered by one rotation of the rotary encoder 140 within a predetermined time interval as the second level signal, and recognize a level signal change within a time interval greater than the predetermined time interval as the first level signal.

[0070] In some examples, the main control board 2 can output a third driving signal to drive the dimming control assembly 4 to control the brightness of the illumination light source 6 after recognizing the third level signal and the third rotation pulse signal.

[0071] In some examples, the switch circuit 7 can be a switch tube circuit composed of one of a triode and a MOS tube. In other examples, the switch circuit 7 can also be a switch tube circuit composed of a thyristor.

[0072] Thus, different functions of the microscope can be triggered by different actions of the multifunctional button 1.

[0073] In some examples, the microscope may further include a stage 11 disposed on a base, a body 9 connected to the base 8, a lifting mechanism 5 disposed within the body 9, and an objective lens connected to the lifting mechanism 5. An illumination light source 6 may be disposed on the body 9 for illuminating a sample to be tested on the stage 11. The multi-function button 1 may be fixed to the base 8 of the microscope. Thus, the lifting mechanism 5 can be used to control the movement of the objective lens 10 relative to the stage 11, and the illumination light source 6 can be used to conveniently illuminate the sample to be tested on the stage 11.

[0074] In this case, the distance between the objective lens 10 and the sample on the stage 11 can be coarsely adjusted by the first control signal, and the distance between the objective lens 10 and the sample on the stage 11 can be finely adjusted by the second control signal.

[0079] Step S300: When the conversion mechanism 120 is in the initial position, the conversion mechanism 120 is rotated to control the rotary encoder 140 to trigger the switch circuit 7 to output a second control signal to the main control board 2;

[0092] In some examples, the first level signal can be different from the second level signal. In some examples, the first level signal can be a level signal output by the switch circuit 7 triggered by one movement of the rotary encoder 140, and the second level signal can be a level signal output by the switch circuit 7 triggered after the rotary encoder 140 is reset.

[0093] In some examples, the level signal output by the switch circuit 7 triggered by one movement of the rotary encoder 140 can be a low level signal, and the level signal output by the switch circuit 7 after the rotary encoder 140 is reset can be a high level signal.

[0094] In some examples, the main control board 2 can output a first driving signal to drive the motor 3 to rotate quickly by identifying the first level signal and the first rotation pulse signal, and the main control board 2 can output the first driving signal to drive the motor 3 to rotate slowly by identifying the second level signal and the second rotation pulse signal. In this case, the motor 3 can be controlled to rotate quickly by the first level signal and the first rotation pulse signal, and the lifting mechanism 5 can be controlled to lift quickly, and the motor 3 can be controlled to rotate slowly by the second level signal and the second rotation pulse signal, and the lifting mechanism 5 can be controlled to lift slowly.

[0095] In some examples, the third level signal can be different from the first level signal and the second level signal. In some examples, the main control board 2 can identify two level signal changes output by the switch circuit 7 triggered by the movement of the rotary encoder 140 within a predetermined time interval as the second level signal, and the main control board 2 can identify a level signal change identified within a time interval greater than the predetermined time interval as the first level signal.

[0096] In some examples, the main control board 2 can output a third driving signal to drive the dimming control component 4 to control the brightness of the illumination light source after recognizing the third level signal and the third rotation pulse signal.

[0097] In some examples, the rotation pulse signal can include a clockwise rotation signal and an anticlockwise rotation signal. Specifically, the first rotation pulse signal can include a first clockwise pulse signal and a first anticlockwise pulse signal, the second rotation pulse signal can include a second clockwise pulse signal and a second anticlockwise pulse signal, and the third rotation pulse signal can include a third clockwise pulse signal and a third anticlockwise pulse signal.

[0098] The first clockwise pulse signal can control the motor 3 to rotate forward at a first rotation speed, and in turn control the lifting mechanism 5 to rise at the first rotation speed, and the first anticlockwise pulse signal can control the motor 3 to rotate reverse at the first rotation speed, and in turn control the lifting mechanism 5 to fall at the first rotation speed; the second clockwise pulse signal can control the motor 3 to rotate forward at a second rotation speed, and in turn control the lifting mechanism 5 to rise at the second rotation speed, and the second anticlockwise pulse signal can control the motor 3 to rotate reverse at the second rotation speed, and in turn control the lifting mechanism 5 to fall at the second rotation speed; the third clockwise pulse signal can control the dimming signal output by the dimming control component 4 to increase, so as to control the illumination light source to become brighter, and the third anticlockwise pulse signal can control the dimming signal output by the dimming control component 4 to decrease, so as to control the illumination light source to become dimmer. In this case, the lifting speed of the lifting mechanism 5 and the brightness of the illumination light source 6 can be conveniently controlled, and coarse adjustment and fine adjustment of the imaging focus in the objective lens 10 can be realized.

[0099] In some examples, the rotation of the outer rotating cap 110 can immediately control the rotation encoder 140 to output the rotation pulse signal to the main control board 2, and the main control board 2 can convert the pulse signal into a driving signal after receiving and recognizing the rotation pulse signal to continuously drive the actuator (the motor 3 or the dimming control component 4) to operate. That is, the actuator can be continuously controlled to operate by giving the outer rotating cap 110 a rotating action.

[0100] In some examples, the main control board 2 can be provided with one of an MCU, an MPU, an FPGA, a DSP, and the like.

[0101] In some examples, the outer rotating cap 110 can drive the conversion mechanism 120 to rotate clockwise or counterclockwise; when adjusting the distance between the objective lens 10 and the sample on the stage 11, the outer rotating cap 110 can be rotated clockwise to drive the lifting mechanism 5 to lower, and the outer rotating cap 110 can be rotated counterclockwise to drive the lifting mechanism 5 to rise; when adjusting the brightness of the illumination light source 6, the outer rotating cap 110 can be rotated clockwise to control the illumination light source to become brighter, and the outer rotating cap 110 can be rotated counterclockwise to control the illumination light source to become dimmer. In this way, by rotating the outer rotating cap 110 clockwise or counterclockwise, the lifting of the lifting mechanism 5 or the brightness of the illumination light source 6 can be conveniently controlled.

[0102] In some examples, a reset spring and a clamping piece can be arranged at one end of the rotary encoder 140 and the contact surface of the conversion mechanism 120, and when the conversion mechanism is displaced inward, the clamping piece can be clamped and then a rotating operation is performed. When a reset is desired, the outer rotating cap 110 can be pressed again to easily reset the conversion mechanism 120 under the action of the reset spring.

[0103] In other examples, the reset mode can also be manual dragging reset.

[0104] In the present embodiment, the above steps S100-S200, steps S300-S400, steps S500-S600 can be independent of each other, and there is no certain sequential relationship.

[0105] In some examples, after the operation steps S100-S200, the outer rotating cap 110 and the conversion mechanism 120 can be reset by dragging or pressing the outer rotating cap 110, and then the steps S300-S400 are performed.

[0106] In some examples, after the operation steps S100-S200, the outer rotating cap 110 and the conversion mechanism 120 can be reset by dragging or pressing, and then the steps S500-S600 are performed.

[0107] In other examples, the steps S100-S600 can be sequentially performed. In this way, the objective lens 10 can be quickly moved close to the sample on the stage 11 by coarse adjustment, and then the objective lens 10 is slowly moved close to the sample on the stage 11 by fine adjustment, and when the distance between the objective lens 10 and the sample on the stage 11 is appropriate, the brightness of the illumination light source 6 is adjusted to facilitate observation of the sample on the stage 11.

[0108] In step S500, the preset time interval of double-clicking can be less than 1 second, so that the quick response of the light adjustment can be realized.

Those skilled in the art can make modifications and changes to the present disclosure as needed without departing from the spirit and scope of the present disclosure, and such modifications and changes fall within the scope of the present disclosure.
