Description

Technical Field

[0001] This invention belongs to the field of geological experimental technology, specifically relating to a miniature, automatically retractable marking system and method. Background Technology

[0002] Currently, determining the internal standard in LA-ICP-MS experiments is extremely complex. First, mineral identification must be performed under scanning electron microscopy, polarizing microscope, and ordinary microscope (transmitted and reflected light). The type of mineral to be tested and the specific location for single-mineral testing must be selected, and the location and sequence number must be marked in CorelDRAW on the reflected light image. Then, referring to the location of the test point in the image, electron probe microanalysis is used to locate the test particle under the microscope, and the experiment is completed. The location and sequence number of the electron probe test point are then marked in CorelDRAW. Finally, the thin section and the image with the marked test particle are placed together in the LA-ICP-MS laboratory, and the location of the test point in the image must again be located before the experiment begins. This method is cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a miniature, automatically retractable marking system and method. This system is simple in structure, easy to operate, and can quickly and accurately locate target minerals required for experiments such as LA-ICP-MS and scanning electron microscopy.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a miniature automatic telescopic marking system, including a cylindrical shell, an internal threaded interface for connecting to the bottom of a microscope lens is provided inside the upper port of the cylindrical shell, a rechargeable battery and a PLC controller are provided in the upper part of the cylindrical shell, a two-stage miniature telescopic rod device is provided in the lower part of the cylindrical shell, a telescopic channel with an open lower end is provided inside the cylindrical shell, and a toner filling channel communicating with the telescopic channel is provided on the radial side of the lower end of the cylindrical shell.

[0005] The two-stage miniature telescopic rod device includes a first electric push rod and a second electric push rod arranged co-centered with the telescopic channel. The first electric push rod includes a guide sleeve, a first push rod, and a first motor. The first push rod is slidably disposed inside the guide sleeve, and the first motor is disposed above the guide sleeve and is drivenly connected to the first push rod. The lower end of the first push rod extends into the telescopic channel. The first push rod and the first motor are provided with a central sliding hole that is open at both ends along the center. The second electric push rod includes a second push rod and a second motor. The second push rod is slidably assembled inside the central sliding hole, and the second motor is disposed above the first motor and is drivenly connected to the upper end of the second push rod.

[0006] The lower end of the first push rod is equipped with a ring-shaped first strain gauge pressure sensor. The first push rod and the first motor have a first through-hole for wire passing through them. The first strain gauge pressure sensor is connected to the input terminal of the PLC controller through a first signal line passing through the first through-hole. The lower end of the second push rod is equipped with a ring-shaped second strain gauge pressure sensor. The second push rod and the second motor have a second through-hole for wire passing through them. The second strain gauge pressure sensor is connected to the input terminal of the PLC controller through a second signal line passing through the second through-hole. The output terminal of the PLC controller is connected to the first motor and the second motor respectively through control lines.

[0007] Both the first strain gauge pressure sensor and the second strain gauge pressure sensor have a ring-shaped, roughened adhesive cloth on their lower surfaces.

[0008] The inner diameter of the first push rod is 2000 μm, and the inner diameter of the second push rod is 500 μm.

[0009] The upper diameter of the cylindrical shell is larger than the lower diameter. The outer circumference of the cylindrical shell is equipped with a power switch connected to a rechargeable battery, a first switch for controlling the opening and closing of the first motor, and a second switch for controlling the opening and closing of the second motor.

[0010] A marking method for a miniature, automatically retractable marking system includes the following steps:

[0011] (1) Connect the internal threaded interface at the upper end of the cylindrical shell to the external threaded connector at the lower end of the microscope lens;

[0012] (2) Select the specified color toner cartridge, connect the toner cartridge with the connecting rod, hold the connecting rod and insert the toner cartridge into the telescopic channel along the toner filling channel. The upper surface of the toner cartridge contacts the adhesive cloth on the lower surface of the first strain gauge pressure sensor and / or the second strain gauge pressure sensor, and the powder adheres to the adhesive cloth.

[0013] (3) Turn on the power switch, observe the particle size on the thin slice through the microscope, and mark the corresponding diameter push rod;

[0014] (4) If the observed particle size is less than 2000μm and greater than 500μm, press the first switch, start the first motor, drive the first push rod to move downward through the transmission mechanism, the lower end of the first push rod extends out of the lower end face of the cylindrical shell, the adhesive cloth at the lower end of the first push rod contacts the particles and marks the particles, and at the same time the first strain gauge pressure sensor transmits the pressure signal to the PLC controller. When the PLC controller receives the pressure signal and the set value is reached, the PLC controller sends a reverse signal command to the first motor, the first motor rotates in the opposite direction, drives the first push rod to move upward to the initial position, and then the first motor automatically shuts off.

[0015] (5) If the particle size is observed to be less than 500μm, press the second switch, the second motor starts, and drives the second push rod to move downward through the transmission mechanism. The lower end of the second push rod extends out of the lower end face of the cylindrical shell, and the adhesive cloth at the lower end of the second push rod contacts the particles to mark them. At the same time, the second strain gauge pressure sensor transmits the pressure signal to the PLC controller. When the PLC controller receives the pressure signal and it reaches the set value, the PLC controller sends a reverse signal command to the second motor. The second motor rotates in the opposite direction, driving the second push rod to move upward to the initial position. After that, the second motor automatically shuts off.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention using the above technical solution are as follows:

[0017] 1. The present invention is equipped with a miniature first electric push rod and a second electric push rod. The extension and retraction of the corresponding push rods are controlled by two motors to mark the target object (particles on the thin sheet). When the adhesive cloth contacts the thin sheet and generates pressure, the PLC controller receives the signal and transmits the command to the pressure sensor. The PLC controller controls the motor to reverse and drive the push rod to automatically retract to its original position to prevent the particle sample from being squeezed and damaged.

[0018] 2. Determining the internal standard in LA-ICP-MS experiments is extremely complex. First, mineral identification must be performed under scanning electron microscopy, polarizing microscope, and ordinary microscope (transmitted and reflected light). The type of mineral to be tested and the specific location for single-mineral testing must be selected, and the location and sequence number must be marked in CorelDRAW on the reflected light photograph. Then, referring to the location of the test point in the photograph, electron probe microanalysis is used to locate the test particle under the microscope to complete the experiment, and the location and sequence number of the electron probe test point are marked in CorelDRAW. Finally, the thin section and the photograph of the marked test particle are placed together in the LA-ICP-MS laboratory, and the location of the test point in the photograph must still be located before starting the experiment. This method is cumbersome, time-consuming, and labor-intensive. In this invention, a miniature automatic telescopic rod system can locate and calibrate the target particle in one step, eliminating the need for repeated searching of the target particle under the microscope by referring to the photograph.

[0019] In summary, this invention is the first to propose the combined use of Raman spectroscopy with experimental instruments such as LA-ICP-MS and scanning electron microscopes. The principle is scientific, the structure is compact, the operation is convenient, and the work efficiency is improved. Moreover, the labeled toner has no effect on subsequent experiments such as LA-ICP-MS and scanning electron microscopes. Attached Figure Description
