Description

Technical Field

[0001] The invention relates to the field of automation, and in particular to an automatic Raman testing system. Background Art

[0002] Raman spectroscopy is a scattering spectroscopy technique based on the interaction between light and matter, which can be used to study the molecular structure, composition and physical properties of materials. Due to its non-destructive, high-resolution and high-sensitivity characteristics, Raman spectroscopy has been widely used in chemistry, physics, biomedicine, materials science and other fields.

[0003] As scientific research and industry have higher requirements for data acquisition speed and accuracy, automated testing has become a trend. Automated testing can not only improve work efficiency, but also reduce human errors and ensure data consistency and reliability. In the field of spectral analysis, automated testing can achieve batch and high-throughput analysis of samples, saving researchers a lot of time.

[0004] When testing samples with Raman, the stage needs to be operated manually. When the number of samples increases, the workload is extremely large and tedious. Although there are many electrically controlled automatic displacement platforms on the market, they cannot be combined with the Raman testing system and cannot meet the requirements of automatic testing. The present invention aims to solve the problems of low automation, low efficiency, and easy errors in manual operation during Raman testing. Summary of the invention

[0005] In view of this, the present invention provides an automatic Raman testing system to achieve automatic positioning, testing and data storage of samples, reduce human intervention, and improve testing efficiency and data accuracy.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] An automatic Raman testing system comprises a three-dimensional mobile platform, a laser confocal micro-Raman spectrometer and a host computer;

[0008] The three-dimensional moving platform includes a stage and a gripper capable of moving in a three-dimensional coordinate system; and is used to move the sample located on the stage to the test table of the laser confocal micro-Raman spectrometer;

[0009] The laser confocal micro-Raman spectrometer is used to test the sample;

[0010] The host computer is equipped with Raman test software and central processing software; wherein the Raman test software is used to record Raman test data, and the central processing software is used to realize the control of the laser confocal micro-Raman spectrometer;

[0011] The samples are placed on the stage and arranged in a rectangular array. The three-dimensional mobile platform moves the samples on the stage to the test table of the laser confocal micro-Raman spectrometer in sequence by gripping the hands, and the laser confocal micro-Raman spectrometer performs Raman detection in sequence. After the Raman test software of the host computer receives the Raman test data, the Raman test data is matched one by one with the samples through the central processing software and stored.

[0012] Furthermore, the central processing software realizes the control of the laser confocal micro-Raman spectrometer by starting the Raman test software; the central processing software includes a storage module, a writing module, a command module and a viewing module;

[0013] The command module is used to have a built-in calculation formula for calculating the time it takes to complete the hand clamping action;

[0014] The writing module is used to record the code of the sample tested this time, and after receiving the test data of the sample, the sample code is matched with its test data, and the storage module stores it;

[0015] After the system officially starts working, the command module calculates the duration of the gripper's action based on the distance from the sample position on the stage to the test bench. When the gripper's movement time meets the conditions, a start signal is sent to the Raman test software, and the Raman test software starts running to start testing the sample. After the test is completed, the write module matches the test data with the sample code and saves it to the storage module. If it needs to be viewed, the staff can retrieve the information of the storage module through the viewing module to view the Raman test data of the sample.

[0016] Furthermore, during the detection process of the laser confocal micro-Raman spectrometer, the clamping hand is returned to its position and prepared for the next round of sample detection.

[0017] Furthermore, the return position of the gripper is located directly above the next round of test samples.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The present invention can improve efficiency: realize the automation of the whole process, significantly reduce the manual operation time, and improve the testing efficiency.

[0020] Reduce errors: Automatically and precisely control the movement of the displacement platform and the execution of the test, reducing the errors caused by human operation.

[0021] Enhanced flexibility: Test parameters can be adjusted according to actual needs to adapt to different test scenarios.

[0022] Easy to implement: It can be implemented by utilizing existing software libraries and equipment without complicated modifications to hardware and software. BRIEF DESCRIPTION OF THE DRAWINGS
