Description

Technical Field

[0001] This utility model relates to the field of spectral detection technology, and in particular to a Raman spectroscopy coal detection device. Background Technology

[0002] Raman spectroscopy is an instrument that uses a laser as an excitation source to analyze the composition of a substance by measuring the Raman spectrum generated by the sample. Raman spectroscopy is widely used in the field of coal detection, where it can analyze the structure of coal and, by observing changes in the degree of coalification, quickly identify the type and quality of coal, providing an important detection method for effectively preventing the import of inferior coal.

[0003] In coal testing, multiple different samples of the same batch of coal usually need to be tested. However, existing testing equipment can only test a single sample at a time. This means that testing a batch of samples requires switching samples multiple times. If multiple different batches of samples need to be tested, the workload of switching samples will be very large. In addition, each time samples are switched, refocusing is required, resulting in low testing efficiency and easy confusion because different batches of samples are waiting to be tested. Utility Model Content

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a Raman spectroscopy coal detection device to solve the problems mentioned in the background section. To achieve this objective, the present invention adopts the following technical solution:

[0005] The Raman spectroscopy coal detection device includes: a fixed base, which is set on the worktable;

[0006] The testing platform is slidably mounted on the fixed base;

[0007] A sample stage is detachably mounted on the detection stage, and multiple sample slots are arranged in sequence.

[0008] A movable base is movably mounted on the fixed base;

[0009] A driving device is disposed on one side of the movable seat, used to drive the movable seat to move along the fixed seat;

[0010] A focusing device is mounted on the movable base;

[0011] The detection probe is mounted on the focusing device.

[0012] Optionally, roller sets are provided on both sides of the movable seat, and roller grooves are provided on both sides of the fixed seat. The two sets of roller sets correspond one-to-one with the two roller grooves and are tumblingly connected.

[0013] Optionally, the driving device includes a servo motor and a gear. The servo motor is disposed on one side of the movable base, and a rack is disposed on one side of the fixed base. The gear is disposed at the working end of the servo motor and meshes with the rack.

[0014] Optionally, the focusing device includes a support base and a linear slide. The support base is disposed on the movable base, the linear slide is disposed on one side of the support base, and the detection probe is disposed at the working end of the linear slide.

[0015] Optionally, the fixed base is provided with a guide rail, and the testing table is slidably disposed on the guide rail.

[0016] Optionally, it also includes a second slide, which is disposed within the fixed base and is used to drive the detection stage to move along the guide rail.

[0017] Optionally, the detection stage is provided with multiple limiting stages, which are used to limit the sample stage.

[0018] Optionally, each of the sample slots has a pick-and-place slot on its periphery, and the pick-and-place slot is connected to the sample slot.

[0019] Compared with the prior art, the advantages of this invention are as follows: By arranging multiple sample slots on the sample stage, samples from the same batch can be placed into multiple sample slots respectively. The detachable design of the testing stage and sample stage facilitates the switching of different batches of samples, and ensures that each batch of samples is placed in one sample stage, avoiding confusion between different batches.

The focusing device drives the vertical movement of the detection probe, which facilitates automatic focusing of the detection probe. The driving device drives the detection probe to move along the fixed base, allowing multiple samples on the sample stage to be tested sequentially, reducing the time for switching samples and improving the testing efficiency.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0030] like Figures 1-4As shown, one embodiment of the present invention is that the Raman spectroscopy coal detection device includes: a fixed base 1, a detection stage 2, a sample stage 3, a movable base 4, a driving device 5, a focusing device 6, and a detection probe 7. The fixed base 1 is horizontally arranged on the top surface of the worktable in the front-back direction.

[0031] The testing platform 2 is slidably mounted on the fixed base 1;

[0032] The sample stage 3 is detachably mounted on the top surface of the detection stage 2, and multiple sample slots 8 are arranged sequentially along the front-back direction;

[0033] The movable base 4 is movably disposed at the rear end of the fixed base 1;

[0034] The drive device 5 is located on the left side of the movable seat 4 and is used to drive the movable seat 4 to move along the fixed seat 1;

[0035] The focusing device 6 is mounted on the movable base 4;

[0036] The detection probe 7 is mounted on the focusing device 6.

[0037] During operation, the testing stage 2 is moved to the front of the fixed base 1 to facilitate material loading by the staff. The staff places multiple sample boxes of the same batch into multiple sample slots 8 of the sample stage 3, places the sample stage 3 on the testing stage 2, and moves the testing stage 2 to the rear of the fixed base 1. The focusing device 6 drives the detection probe 7 to move vertically to focus on and detect the first sample on the sample stage 3. The driving device 5 drives the moving base 4 to move forward so that the detection probe 7 can detect the sample in each sample slot 8.

[0038] This application arranges multiple sample slots 8 on the sample stage 3, allowing samples from the same batch to be placed into the multiple sample slots 8 respectively. The detachable arrangement of the detection stage 2 and the sample stage 3 facilitates the switching of samples from different batches and avoids confusion between samples from different batches. The sliding arrangement of the detection stage 2 and the fixed base 1 makes it easy for the operator to pick up and put down the sample stage 3 at the front of the workbench. The focusing device 6 drives the detection probe 7 to move vertically, which facilitates the automatic focusing of the detection probe 7. The driving device 5 drives the detection probe 7 to move back and forth, so that multiple samples on the sample stage 3 can be detected sequentially, reducing the time for switching samples and improving the detection efficiency.

[0039] In one embodiment, such as Figure 2 As shown, roller sets 41 are respectively provided on the left and right sides of the movable seat 4, and roller grooves 11 are respectively provided on the left and right sides of the fixed seat 1 along its length direction. The two sets of roller sets 41 correspond one-to-one with the two roller grooves 11 and are connected in a rolling manner.

[0040] It is understood that each set of rollers 41 includes at least two rollers. The roller set 41 on the left side of the movable seat 4 is tactilely connected to the roller groove 11 on the left side of the fixed seat 1, and the roller set 41 on the right side of the movable seat 4 is tactilely connected to the roller groove 11 on the right side of the fixed seat 1, so that the movable seat 4 can move and roll. Both ends of the roller groove 11 can be used to limit the roller set 41.

[0041] In one embodiment, such as Figure 2 As shown, the drive device 5 includes a servo motor 51 and a gear 52. The servo motor 51 is located on the left side of the movable seat 4. A rack 53 is provided on the left side of the fixed seat 1 along the front-back direction. The gear 52 is located at the working end of the servo motor 51 and meshes with the rack 53. The servo motor 51 drives the gear 52 to rotate, and the gear 52 moves along the rack 53, thereby causing the movable seat 4 to move along the front-back direction of the fixed seat 1, thereby driving the detection probe 7 to detect multiple samples on the sample stage 3 in sequence.

[0042] In one embodiment, such as Figure 3 As shown, the focusing device 6 includes a support base 61 and a linear slide 62. The support base 61 is vertically disposed on the top surface of the movable base 4, and the linear slide 62 is vertically disposed on the front side of the support base 61. The detection probe 7 is vertically disposed on the working end of the linear slide 62. The linear slide 62 is used to drive the detection probe 7 to move vertically, thereby realizing the focusing work of the detection probe 7.

[0043] In one embodiment, such as Figure 4 As shown, a guide rail 12 is provided on the fixed base 1 along the front-back direction. The detection table 2 is slidably mounted on the guide rail 12. In order to maintain the stability of the movement of the detection table 2, there are two guide rails 12, which are arranged parallel to each other on the fixed base 1.

[0044] In one embodiment, such as Figure 4 As shown, it also includes a second slide 9, which is set in the fixed base 1 and is used to drive the detection stage 2 to move along the guide rail 12, so that the sample stage 3 can be loaded and unloaded at the front end of the fixed base 1 and detected at the rear end.

[0045] In one embodiment, such as Figure 5 As shown, the detection stage 2 is provided with multiple limiting platforms 21, which are used to limit the sample stage 3. In this embodiment, the sample stage 3 is rectangular, and four limiting platforms 21 are respectively provided on the top surface of the detection stage 2 corresponding to the four sides of the sample stage 3. The four limiting platforms 21 are used to limit the sample stage 3 around its perimeter, which facilitates fixing the sample stage 3 during loading and prevents it from shifting during movement.

[0046] In one embodiment, such as Figure 5As shown, each sample slot 8 has a pick-and-place slot 81 on its periphery. The pick-and-place slot 81 is connected to the sample slot 8. The pick-and-place slot 81 makes it easy for workers or robotic arms to grab the sample boxes in the sample slot 8, which facilitates loading and unloading and improves the efficiency of sample switching.

[0047] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
