The nondestructive spectrum analysis technology is gradually becoming an indispensable analysis means in the industries of agriculture, food, industry and mining and the like. The spectrum detection device comprises a sample cup, a mounting seat and a spectrum detector, wherein the sample cup is arranged on the mounting seat, a sample to be detected is placed in the sample cup, and spectrum data of the sample to be detected is obtained through the spectrum detector. However, when the conventional spectrum detection device is used, the area of the spectrum detector scanning the sample is relatively fixed, so that the accuracy of the measured spectrum data is low.

In view of the above, through intensive research, a spectrum detection apparatus has been devised which can improve the accuracy of obtained spectrum data when in use.

FIG. 1 is an exploded schematic view of a spectral detection device 10; FIG. 2 is a partially exploded view of the spectrum detecting device 10; FIG. 3 is a schematic assembly view of a portion of the spectrum detecting apparatus 10 shown in FIG. 2; fig. 4 is a schematic diagram of a partial structure of the spectrum detecting apparatus 10 of fig. 3 at one of the viewing angles.

Referring to fig. 1 to 5, the spectrum detecting apparatus 10 includes a detecting component 100, a supporting mechanism 200, a sample accommodating component 300 and a driving component 400. The sample holding assembly 300 is used for holding a sample to be detected, the sample to be detected can be granular or powder, the detection assembly 100 is used for acquiring spectral information of the sample to be detected, and the type of the sample to be detected can be detected through the spectral information.

Referring to fig. 1 to 4, the supporting mechanism 200 is connected to the detecting assembly 100, and the supporting mechanism 200 forms a supporting portion. The sample holding assembly 300 can be suspended relative to the detection assembly 100 under support from a support. The sample-receiving component 300 is suspended relative to the testing component 100, as the name suggests, in which case the sample-receiving component 300 does not directly contact the testing component 100, but is spaced apart from the testing component so that no frictional resistance is created between the two when the sample-receiving component 300 is moved, such as by rotation or movement.

Referring to fig. 2 and 3, the detecting assembly 100 is provided with a detecting region 122 for detecting light to pass through, and the sample holding assembly 300 includes a light-transmitting portion 3224, wherein the light-transmitting portion 3224 faces a side of the detecting assembly 100 where the detecting region 122 is formed, and a center of the detecting region 122 is offset from a center of an orthographic projection area of the light-transmitting portion 3224 on the detecting assembly 100. The detection light can be emitted by a corresponding spectrum module, the spectrum module can be arranged on one side, deviating from the sample accommodating component 300, of the detection area 122, the spectrum module emits the detection light to the light transmission portion 3224, the detection light is transmitted to the sample to be detected, and the sample to be detected is transmitted back to the spectrum module after a series of optical transmission such as reflection or diffuse reflection, so that the spectrum information of the sample to be detected is obtained, and the type of the sample to be detected is judged.

Here, the light-transmitting portion 3224 of the sample accommodating member 300 is a portion through which the detection light emitted from the detection member 100 passes.

Referring to fig. 1 and fig. 3, the driving member 400 is in driving fit with the sample accommodating component 300, the driving member 400 is used for driving the sample accommodating component 300 to rotate, and the light-transmitting portion 3224 is driven by the sample accommodating component 300 to rotate relative to the detection region 122, so as to switch the area of the light-transmitting portion 3224 corresponding to the detection region 122.

Referring to fig. 3, the rotation direction of the sample holding assembly 300 may be the direction F in the drawing, and the direction F in fig. 3 is the clockwise direction, but this does not mean that the sample holding assembly 300 is limited to rotate clockwise, the sample holding assembly 300 may also rotate counterclockwise according to the requirement, and the specific rotation direction may be set according to the requirement.

Referring to fig. 1 to 4, when the spectrum detection apparatus 10 is used, the driving member 400 drives the sample accommodating component 300 to rotate, and the light-transmitting portion 3224 is driven by the sample accommodating component 300 to rotate relative to the detection region 122, so as to switch the area of the light-transmitting portion 3224 corresponding to the detection region 122, thereby increasing the area of the detection region 122 scanning the light-transmitting portion 3224, and further improving the accuracy of the detection result.

The manner in which the support supports the sample-receiving component 300 in suspension relative to the detection component 100 can be varied: for example, the supporting portion may be a supporting ring, the sample holding assembly 300 is inserted into the supporting ring, and the outer wall of the sample holding assembly 300 is formed with an overlapping rib, and the overlapping rib is overlapped with the supporting ring, so as to support the sample holding assembly 300 to suspend relative to the detecting assembly 100; alternatively, the supporting portion includes at least three supporting portions, and the sample assembly is supported and clamped by the three supporting portions from at least three different directions to be suspended relative to the sample holding assembly 300. Of course, the support portion may also suspend the sample holding assembly 300 above the detecting assembly 100 by means of magnetic levitation.

Referring to fig. 2 and 3, in one embodiment, the supporting mechanism 200 includes at least three mounting shafts 210, the supporting portion includes at least three bearings 220, one of the bearings 220 is connected to the detecting assembly 100 through one of the mounting shafts 210, and the at least three bearings 220 are spaced apart and fit against the sample-containing assembly 300 to suspend the sample-containing assembly 300 relative to the detecting assembly 100.

It should be noted that, according to the basic structural knowledge of the bearing 220, the bearing 220 generally comprises an inner ring and an outer ring, the inner ring is used for matching the mounting shaft 210, and the outer ring is used for butting and matching with the sample holding component 300.

It will be appreciated that the reason for defining the number of mounting shafts 210 to be at least three is that the stability against the sample receiving assembly 300 is optimal in at least three positions.

When the number of the bearings 220 is three, three bearings 220 may be disposed at intervals and located on the same circumference, and a central angle formed between two adjacent bearings 220 is 120 °. When the number of the bearings 220 is four, the four bearings 220 may be located on the same circumference, and a central angle formed between two adjacent bearings 220 may be 90 °. When the number of the bearings 220 is more than 4, all the bearings 220 may still be arranged at intervals and located on the same circumference, and the central angle formed between two adjacent bearings 220 may be set according to the number of the bearings 220, as long as all the bearings 220 can be abutted against the sample accommodating component 300 in a matching manner to suspend the sample accommodating component 300 relative to the detection component 100.

It will be appreciated that the drive member 400 provides rotational power to the sample receiving assembly 300. The driving member 400 may be any driving means known in the art that can provide rotational power.

For example, referring to fig. 2 and 3, in some embodiments, the driving member 400 includes a rotary power source 410 and a guide wheel 420 disposed at an output end of the rotary power source 410, the guide wheel 420 is in contact with and engaged with the sample-accommodating member 300, the guide wheel 420 can be driven by the rotary power source 410 to rotate, and the sample-accommodating member 300 rotates by a friction force between itself and the guide wheel 420, so that the sample-accommodating member 300 is driven to rotate while a rotation resistance of the sample-accommodating member 300 is relatively low.

Alternatively, the rotary power source 410 may be mounted to the mounting plate 110 by means of screws.

Alternatively, the rotational power source 410 may be a driving motor, and the guide pulley 420 is connected to a rotation shaft of the driving motor.

Fig. 5 is an exploded view of the sample-receiving component 300, and fig. 6 is an assembled view of the sample-receiving component 300. Referring to fig. 1, 5 and 6, the sample holding assembly 300 includes an overhead guide ring 310 and a sample cup 320, the supporting portion is used for supporting the overhead guide ring 310 to suspend the overhead guide ring 310 relative to the detecting assembly 100, the sample cup 320 is inserted into the overhead guide ring 310, and the bottom of the sample cup 320 is provided with a light-transmitting portion 3224.

Referring to fig. 5, in one embodiment, the outer wall of the overhead guide ring 310 is formed with an abutting groove 312, and the bearing 220 abuts against the groove edge of the abutting groove 312. Guide wheel 420 is in contact engagement with the slot edge of abutment recess 312.

The overhead guide ring 310 and the sample cup 320 may be integrated or may be respectively a single structure, and at this time, the sample cup 320 is disposed in the overhead guide ring 310 by a corresponding connection manner. When the sample cup 320 and the overhead guide ring 310 are of an integral structure, since the support portion needs to support against the overhead guide ring 310, when the overhead guide ring 310 or the sample cup 320 needs to be cleaned and maintained, it is difficult to detach the overhead guide ring 310 and the sample cup 320 from the support portion, and therefore, the overhead guide ring 310 and the sample cup 320 are preferably of a single structure, and the sample cup 320 and the overhead guide ring 310 are detachably connected.

For example, referring to fig. 5 and 6, in some embodiments, the outer wall of the sample cup 320 is formed with an abutting protrusion 3222, and the abutting protrusion 3222 is in abutting fit with an end edge of the overhead guide ring 310 away from the detection assembly 100. Thus, when the sample cup 320 needs to be cleaned, the sample cup 320 needs to be removed from the overhead guide ring 310.

The abutting protrusion 3222 may be formed on an end edge of the sample cup 320 far from the detection assembly 100, or on a middle edge of the sample cup 320, and the specific forming position may be set as required.

The abutment protrusions 3222 may be snap-fit ribs. The lap joint rib can be a complete annular rib, and also can be a 3/4 arc lap joint rib, and the specific structure can be set as required as long as the sample cup 320 can be lapped with the overhead guide ring 310 through the abutting protrusion 3222 so as to be inserted into the overhead guide ring 310.

In some embodiments, the sample cup 320 may be a one-piece structure, and the bottom of the sample cup 320 may be made of various transparent materials such as glass, silicon fluoride, quartz, etc.

Figure 5 illustrates an alternative construction of a sample cup 320. Referring to fig. 5, in other embodiments, the sample cup 320 includes a cup body 322 with two open ends and a hollow interior, the light-transmitting portion 3224 is a light-transmitting element, the cup body 322 is inserted into the overhead guide ring 310, and the light-transmitting element is disposed in the overhead guide ring 310 and surrounds an inner wall of the overhead guide ring 310 to form a receiving cavity for receiving a sample.

The light-transmitting element can be a quartz plate or a light-transmitting plate made of other light-transmitting materials.

Referring to fig. 5 and 6, the sample testing assembly 100 further includes a height-increasing ring 330, the height-increasing ring 330 is in sleeved fit with the sample cup 320, and the height-increasing ring 330 is disposed in a protruding manner along the height direction of the sample cup 320 relative to the sample cup 320. Therefore, the height of the sample cup 320 can be increased by arranging the increasing ring 330, the probability that light leakage or other stray light enters the sample cup 320 is reduced, and the detection accuracy of the sample to be detected is improved.

FIG. 7 is an exploded view of the raising ring 330 and the sample cup 320. Referring to fig. 6 and 7, in some embodiments, the raised ring 330 may be threadably coupled to the sample cup 320. Specifically, one of the heightening ring 330 and the sample cup 320 may be provided with an external thread structure, and the other one may be provided with an internal thread structure, which are connected by a screw fit between the internal thread structure and the external thread structure.

Therefore, the light shielding plate 120 shields the first mounting hole 112, so that other stray light is difficult to enter the first mounting hole 112, and the detection of the sample to be detected is influenced.

Alternatively, the light shielding plate 120 may be fixed to the side of the mounting plate 110 facing away from the supporting mechanism 200 by gluing or screwing.

The light-transmitting portion 3224 is disposed in the first mounting hole 112, and thus, the light-transmitting portion 3224 is accommodated in the first mounting hole 112, so that other stray light can be prevented from entering the light-transmitting portion 3224.

The center of the area of the light transmissive member in the orthographic projection of the light shielding plate 120 is offset from the center of the detection hole 1222, and thus, when the overhead guide ring 310 is rotated, the respective areas of the light transmissive member can sequentially pass through the detection hole 1222, and further areas of the light transmissive member can be scanned.

Referring to fig. 1, the detecting assembly 100 further includes a stopping plate 140, the stopping plate 140 is disposed at a side of the light shielding plate 120 close to the sample accommodating assembly 300 and disposed in the first mounting hole 112, the stopping plate 140 is provided with a light screening portion, and the light screening portion and the detecting region 122 correspond to each other and are used for screening light with a predetermined wavelength, passing through the light screening portion and transmitting the light to the light-transmitting portion 3224.

Specifically, the light screening portion may be a light filtering portion, and the light transmitting portion may be made of light-transmitting quartz, an absorption or reflection type narrow band filter (filter), or an absorption or reflection type cut-off filter (filter).

The cut-off plate 140 may be made of various metal materials such as aluminum alloy, titanium alloy, nickel-copper alloy, and the like. The thickness of the cut-off plate 140 may be 0.5mm to 3mm, and the thickness of the cut-off plate 140 is selected according to the application scenario of the spectrum detection apparatus 10.

The stop plate 140 is fixed on the bottom wall of the first mounting hole 112 by a flat head screw, when the disassembly is required, the stop plate 140 can be vertically taken out/replaced by a sucking disc tool only after the screw is taken out, other parts are not required to be disassembled, and the disassembly is convenient.
