Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail the present invention detailed description of the invention.As shown in Figure 1, a kind of sample auto-feed test accessories, including fixed mount 1, motor 6, plate 7, rotating disk 8 and platen 9, described plate is flexibly connected with described fixed mount, described motor is fixed on described plate, the output shaft of described motor is connected with described rotating disk by key, and described rotating disk is provided with the first through hole 11；Described platen size is identical with described rotating disk, and platen is flexibly connected with described rotating disk by securing member, and described platen is provided with the second through hole 12, and quantity and the size of described second through hole are identical with quantity and the size of the first through hole on described rotating disk.This structure need not repeatedly open sample bin, thus avoid and have influence on test environment, only need to shift to an earlier date and testing sample is fixed between rotating disk and platen.The mode of the flexible connection that above-mentioned several parts all use is fixed, the most readily accessible and maintenance.
In order to accurately control the rotational angle of motor, control the turned position of rotating disk, pass through to be bonded on the output shaft of described motor to be connected to zero-detection sheet 3, the top of described plate is provided with fixing rack for sensor 5, being provided with sensor 4 on described fixing rack for sensor, described sensor is for sensing the position signalling of described zero-detection sheet.
Damage the most under external force owing to motor and sensor are chronically exposed to outer one side, on the other hand operator also can be produced harm, in order to solve the problems referred to above, described motor extenal fixation has motor cover 2, and described motor cover leaves the cable hole of motor and sensor.Arranging motor cover is for overall attractive in appearance of adnexa, and protection motor and the safety of staff thereof.
As a further improvement on the present invention, described fixed mount is made up of base plate 13 and the limiting plate 14 being fixed on base plate both sides, with bolt fixing hole 15 on base plate, side corresponding on described limiting plate is vertically provided with stopper slot 16, and the both sides of described plate are slidably matched with described stopper slot respectively.Fixed mount can be fixed in sample bin by the fixing hole on base plate, prevents adnexa from moving integrally, impact test effect, it addition, use two limiting plates to be fixed by plate, it is simple to installation and removal.
In the present invention, described securing member includes fastening bolt 17 and the locking button 10 coordinated with it, and described fastening bolt is vertically fixed in the card of described rotating disk, and the platen corresponding with described fastening bolt is provided with bolt through-hole 18.When mounted, rotating disk and platen, through the bolt through-hole on platen, are fixed, simple operation, it is possible to quickly test sample be arranged on rotating disk and platen between the through hole of correspondence by the fastening bolt on rotating disk by locking button.
For Appropriate application motor, saving space, the output shaft of described motor is divided into front output shaft and rear output shaft, described rotating disk to be fixed on front output shaft, and described zero-detection sheet is fixed on rear output shaft.Front output shaft and rear output shaft are typically all an axis, and the present invention reasonably make use of this root axis, are that present configuration is compacter.
Being provided with third through-hole in the middle part of described plate, described third through-hole is corresponding with described first through hole and the second through hole.Working as electric machine rotation, when driving rotating disk to rotate, when each through hole forwards extreme lower position to, now incident illumination passes through from here.Certainly this is optimum mode, and the first through hole and the second through hole can also turn to side or top, and incident illumination passes from this position.
Installation steps: first fixed mount 1 is fixed on the sample bin of infrared spectrometer；
2. will be an entirety after the outer miscellaneous part of fixed mount 1, miscellaneous part assemble, in the middle of the first through hole at this moment fixing sample (having light transmission) to be measured can being placed on rotating disk 8, then by platen
9 cover on rotating disk 8, then lock with locking button 10, remarks: can certainly fix multiple testing sample, current rotating disk 8 has position, 4 holes, can fix 3 testing samples, because one of them hole is in order to infrared spectrometer gathers used by empty background spectrogram.
The most then insert on fixed mount 1 by plate 7, accessory tapes has the most had testing sample fix in instrument sample storehouse；
4. driving rotating disk 8 to realize stepping followed by motor 6 to rotate, the precision of electric machine rotation and reset are to realize control by sensor 4；Sensor 4 is fixed on fixing rack for sensor 5；Zero-detection sheet 3 has been yes, and sensor 4 controls motor 6 realization reset；
5., for the safety of the attractive in appearance of adnexa He operator, turn round and look at and have employed motor cover 2 by adnexa major part cover；Leave motor and sensor cable hole simultaneously.
In use, it is only necessary to fixed mount is installed in the sample bin of infrared spectrometer instrument；In addition to fixed mount, other parts assembled can be inserted in fixed mount by plate, owing to each parts use the mode of flexible connection, thus can realize conveniently picking and placeing；Motor realizes stepping and rotates, and control accuracy and reset are realized by sensor and zero-detection sheet；Step motor drive rotating disk rotates, and platen is fixed on rotating disk by locking button；Test sample is fixed in hole site in the middle of rotating disk and platen.This structure need not repeatedly open sample bin, thus avoid and have influence on test environment, only need to shift to an earlier date and testing sample 21 is fixed between rotating disk and platen.Incident illumination 19 forms emergent light 20 after being radiated in test sample 21.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
