This instrument is known for its simple structure, easy operation, fast, efficient and accurate measurement, and its low wavenumber measurement ability; it adopts a confocal optical path design to obtain higher resolution, can perform micro-area detection at the um level on the sample surface, and can also be used for microscopic image measurement.

[0086] Such as Figures 1 - 4 and Figure 7As shown in the figure, the present invention provides a Raman spectroscopy detection device with an efficient detection function, including a support mechanism 1, a laser generator 2, a spectrometer 3, a Raman head 4, and a motion platform 5. The support mechanism 1 is used to support the laser generator 2, the spectrometer 3, the Raman head 4, and the motion platform 5. After being powered on, the laser generator 2 can generate laser rays for Raman detection, and the laser rays are transmitted to the Raman head 4 through an optical fiber. The Raman head 4 is used to emit the laser transmitted by the laser generator 2 to the sample and receive the laser reflected by the sample, and transmit the reflected laser to the spectrometer 3 through an optical fiber. The spectrometer 3 is used to receive the signal of the laser fed back by the Raman head 4, and can output the Raman spectrum according to the reflected spectrum, and output or store the results analyzed by the Raman spectrum through devices such as a host computer and a PC. The motion platform 5 is used to drive the Raman head 4 and the sample to be detected to move respectively, so that the Raman head 4 and the sample in the sample well plate 10 can interact quickly, realizing batch and rapid detection.

[0087] The support mechanism 1 further includes a support frame for supporting each component. The support frame includes a support base 101, a vertical support frame 102, a vertical equipment box 103, and a horizontal equipment box 104. The support base 101 is arranged at the lowermost end of the entire support frame and serves to connect and support the equipment. A longitudinally distributed guide rail 503 can be installed on the top of the support base 101, and a slider 504 is arranged on the guide rail 503. The slider 504 is driven by a motor and rollers to drive a belt, so that the slider 504 can reciprocate in the longitudinal direction, forming a longitudinal motion device. The longitudinal motion device is used to drive the sample to move in the longitudinal direction. There are two vertical support frames 102, and the two vertical support frames 102 are respectively vertically arranged at the edges on the left and right sides of the top of the support base 101. A plurality of horizontal slide table mounting holes 105 are provided in the upper parts of the two vertical support frames 102. The guide rail 503 for supporting the horizontal slider is installed between the two vertical support frames 102 through the horizontal slide table mounting holes 105. A motor mounting bracket 106 is installed on the side surface of one of the vertical support frames 102 for installing the motor that drives the horizontal slider 504 to move. A roller mounting plate 107 is arranged on the inner wall of the other vertical support frame 102, and rollers are installed on the roller mounting plate 107. A belt is arranged between the output shaft of the motor and the rollers, and the horizontal slider 504 is driven by the belt to reciprocate in the horizontal direction, forming a motion device in the horizontal direction. At this time, the Raman head 4 connected to the horizontal slider 504 will move simultaneously to quickly detect the sample. The vertical equipment box 103 is arranged at the rear end of the top of the support base 101, and a lower computer 6, an interface board 7, and a power supply are installed inside the vertical equipment box 103. The lower computer 6 is used to control the Raman spectroscopy detection device and perform signal interaction with an external upper computer. The interface board 7 is used to connect the power supply and each functional device in the Raman spectroscopy detection device. A lower computer interface slot and a power supply interface slot are respectively arranged on the same side surface of the vertical equipment box 103. The lower computer interface slot is used to facilitate the connection of the circuit with the lower computer, and the power supply interface slot is used to facilitate the external connection of the power supply. A rear cover is arranged at the rear end of the vertical equipment box 103 to cover the opening of the vertical equipment box 103, and lead wire heat dissipation holes are arranged on the front surface of the vertical equipment box 103. The circuit of the motion platform motor enters the inside of the vertical equipment box 103 through the lead wire heat dissipation holes and is connected to the interface board 7, so that the motion platform 5 can be controlled by the lower computer 6.

[0088] The horizontal device box 104 is arranged on the top of the vertical support frame 102 and the vertical device box 103 and is supported. A spectrum analyzer interface slot is arranged on the same side of the horizontal device box 104 as the lower computer interface slot, and the spectrum analyzer interface slot is used to enable the line of the spectrometer 3 to be conveniently connected to the lower computer 6. A vertical ventilation wiring slot is arranged at the inner bottom of the horizontal device box 104. The vertical ventilation wiring slot is used to allow air to circulate to the inside of the horizontal device box 104. When necessary, the line can also pass through the position of the vertical ventilation wiring slot. A sealing cover is arranged on the top of the horizontal device box 104 to isolate the inside of the horizontal device box 104. A fiber optic outlet 108 is arranged on the front of the sealing cover, and the optical fiber of the spectrometer 3 and the laser generator 2 inside the horizontal device box 104 can pass through the fiber optic outlet 108 to connect with the Raman head 4.

[0089] A communication hole is provided at the rear end of the top of the vertical device box 103, and a wire hole groove matching the communication hole is provided at the rear end of the bottom of the horizontal device box 104, so that the interiors of the vertical device box 103 and the horizontal device box 104 are connected, so as to facilitate the entry of cables in the vertical device box 103 into the horizontal device box 104, facilitate wiring and improve air circulation between the vertical device box 103 and the horizontal device box 104. The back cover and the sealing cover are both detachably installed at the openings of the vertical device box 103 and the horizontal device box 104. When installing and maintaining the equipment, the convenience of maintenance can be improved by removing the back cover or the sealing cover.

[0090] by Figure 5 Taking the sample hole plate 10 shown as an example, the motion platform 5 drives the Raman head 4 and the sample hole plate 10 to move respectively, so that the Raman head 4 can quickly scan the hole of the sample hole plate 10. If there is a sample in the hole, the Raman spectrum of the sample is output. And the Raman spectrum output by each sample will be stored once, and the coordinates when the Raman spectrum is obtained will be recorded to facilitate subsequent distinction. If there is no sample in the hole, then the output is an ordinary Raman spectrum. By shielding the ordinary Raman spectrum in advance, a complete sample Raman spectrum can be obtained.

[0091] The laser generator 2, the spectrometer 3, the Raman head 4 and the motion platform 5 are all arranged on the supporting mechanism 1. The laser generator 2 can transmit laser rays to the Raman head 4 through optical fiber. The optical path coupling between the spectrometer 3 and the Raman head 4 can form signal interaction, and the reflected signal received by the Raman head 4 is input into the spectrometer 3 for analysis.

[0092] The motion platform 5 includes a transverse moving member 501 and a longitudinal moving member 502. The Raman head 4 and the sample to be detected are respectively arranged on the transverse moving member 501 and the longitudinal moving member 502. The Raman head 4 and the sample to be detected can move along with the driving of the transverse moving member 501 and the longitudinal moving member 502, so that the Raman head 4 can scan all the holes on the sample well plate 10. Moreover, the transverse moving member 501 and the longitudinal moving member 502 move synchronously, which can effectively reduce the moving stroke of the Raman head 4 and the sample well plate 10, greatly reduce the time for sample detection, and improve the detection efficiency. When the Raman head 4 and the sample to be detected are vertically collinear, the transverse moving member 501 and the longitudinal moving member 502 can temporarily stop moving. At this time, the laser generator 2 emits detection laser to the Raman head 4. The Raman head 4 enters the detection state, emits laser to the sample, and receives the reflected laser signal, and synchronously transmits the laser signal to the spectrometer 3 for analysis. After this operation is completed, the transverse moving member 501 and the longitudinal moving member 502 continue to work to prepare for the detection of the next position.

[0093] The motion platform 5 is driven by a transmission device. The transmission device includes two driving components 505. The output ends of the two driving components 505 are both provided with driving wheels for power transmission. The two driving components 505 are respectively a longitudinal driving motor and a transverse driving motor. The output end of the longitudinal driving motor is arranged in the vertical direction, and the output end of the transverse driving motor is arranged longitudinally. The longitudinal driving motor and the transverse driving motor are both servo motors and are controlled by a PLC control board. During operation, the PLC control board is used to control the longitudinal driving motor and the transverse driving motor to work synchronously and make the working frequencies of the longitudinal driving motor and the transverse driving motor the same. A longitudinal driven wheel is arranged on the longitudinal extension line of the output end of the longitudinal driving motor. The driving wheel at the output end of the longitudinal driving motor and the longitudinal driven wheel cooperate to support a longitudinal transmission belt, so that both ends of the longitudinal transmission belt are supported and the longitudinal transmission belt is straightened. A longitudinal traction block is arranged on the longitudinal transmission belt. When the longitudinal transmission belt is driven by the longitudinal driving motor, the longitudinal transmission belt will drive the longitudinal traction block to perform longitudinal displacement.

[0094] A transverse driven wheel is arranged on the horizontal extension line of the output end of the transverse driving motor. The driving wheel at the output end of the transverse driving motor and the transverse driven wheel cooperate to support a transverse transmission belt, so that both ends of the transverse transmission belt are supported and the transverse transmission belt is straightened. A transverse traction block is arranged on the transverse transmission belt. When the transverse transmission belt is driven by the transverse driving motor, the transverse transmission belt will drive the transverse traction block to perform transverse displacement.

[0095] The outer surfaces of all driving wheels, longitudinal driven wheels, and transverse driven wheels are provided with grooves. The longitudinal transmission belt and the transverse transmission belt are both restricted within the grooves. When driving the longitudinal transmission belt and the transverse transmission belt respectively through the longitudinal driving motor and the transverse driving motor, it is avoided that the longitudinal transmission belt and the transverse transmission belt deviate due to changes in friction and force application points, which affects the driving accuracy. Tooth teeth are provided inside the grooves of all driving wheels, longitudinal driven wheels, and transverse driven wheels, and tooth grooves are provided on the inner walls of the longitudinal transmission belt and the transverse transmission belt. The tooth teeth and the tooth grooves mesh with each other. When the longitudinal transmission belt and the transverse transmission belt are under load, if the contact surfaces between the driving wheels, longitudinal driven wheels, and transverse driven wheels and the longitudinal transmission belt and the transverse transmission belt are smooth surfaces, slipping is likely to occur, resulting in inaccurate transmission. Therefore, tooth teeth and tooth grooves are provided to mesh for transmission to improve the accuracy of transmission.

[0096] As Figure 1 and Figure 2 shown, in some embodiments, both the lateral moving member 501 and the longitudinal moving member 502 of the present invention include a guide rail 503, a slider 504, and a driving component 505. The guide rail 503 in the lateral moving member 501 and the guide rail 503 in the longitudinal moving member 502 are vertically arranged in a top view state, so that the Raman head 4 and the sample well plate 10 have a common intersection point during the movement process. When the Raman head 4 is at the intersection point, a detection operation is performed. The slider 504 is arranged on the guide rail 503 and is supported and limited by the guide rail 503, so that the slider 504 can only move along the track of the guide rail 503. The driving component 505 can drive the slider 504 to displace at a constant speed, so that the intersection time between the Raman head 4 and the wells of the sample well plate 10 remains stable. Among them: The lateral moving member 501 is installed at the upper part between two vertical support frames 102. The lateral moving member 501 is used to drive the Raman head 4 in the Raman spectroscopy detection device to move laterally. The Raman head 4 is connected to the spectrometer 3 and the laser generator 2 through optical fibers. The longitudinal moving member 502 is arranged on the top of the support base 101. The longitudinal moving member 502 is used to drive the external sample well plate 10 to move longitudinally. Samples to be detected can be injected into the wells of the sample well plate 10. The lateral moving member 501 and the longitudinal moving member 502 can respectively drive the Raman head 4 and the sample well plate 10 to generate several intersection points during the movement. When the Raman head 4 and the wells of the sample well plate 10 intersect at a predetermined position, the Raman head 4 emits laser light and receives the laser light reflected by the sample, realizing one detection. After one detection is completed, the lateral moving member 501 and the longitudinal moving member 502 continue to drive the Raman head 4 and the sample well plate 10 to move to the next detection point through the moving slider for Raman spectroscopy detection of the sample.

[0097] This application illustrates the movement relationship between the Raman head 4 and the sample well plate 10 by way of example:

[0098] The Raman head 4 and the sample well plate 10 are respectively moved to the topmost positions of the transverse moving member 501 and the longitudinal moving member 502, and this position is set as the initial point. Subsequently, the transverse moving member 501 and the Raman head 4 move simultaneously, so that the Raman head 4 quickly moves to the designated position, and all the wells of the sample well plate 10 are scanned in sequence. Then, the longitudinal moving member 502 drives the sample well plate 10 to move a row distance along the trajectory direction of the longitudinal moving member 502, so that the Raman head 4 can scan the wells in the next row, and all the wells are scanned in sequence.

[0099] It should be noted that the above examples are just one of the solutions. The scanning path can be set by the host computer, and the initial scanning path and skipped path can be set to further improve the efficiency of Raman detection.

[0100] As Figure 1 shown, in some embodiments, the driving component 505 of the present invention is a programmable motor, and a coordinate initialization module 506 is installed on the driving component 505. The coordinate initialization module 506 is specifically a control board with servo motor torque control logic. For example, the MS1H3-75C15CD-A331R-ZL model in the Inovance MS1-ZL series servo motors supports torque control, etc. The function of the coordinate initialization module 506 is to make the transverse moving member 501 and the longitudinal moving member 502 return to the initial coordinate points before power-on and after power-off, so as to improve the accuracy of equipment operation and automatically correct the coordinate deviation caused by long-term use. The specific working principle of the coordinate initialization module 506 is to issue an instruction to make the driving component 505 drive the slider 504 to move towards the initial point coordinate all the time until the driving component 505 cannot drive the slider 504 to move, and then instruct the driving component 505 to stop. At this time, the sliders 504 in the transverse moving member 501 and the longitudinal moving member 502 are both in the initial position, that is, the zero coordinate, realizing coordinate initialization. Compared with judging the coordinate position of the slider 504 by monitoring the torque generated by the driving component 505, this device is more stable and will not cause coordinate errors due to factors such as the wear of the guide rail 503 and the slider 504 and the change of the friction coefficient. The driving motors in the transverse moving member 501 and the longitudinal moving member 502 are both servo motors, and both driving motors are equipped with adapted PLC control boards. When performing Raman spectroscopy detection on the sample, the driving motors are driven and set through the PLC control boards, so that the Raman head 4 and the sample well plate 10 can move precisely according to the setting. When some of the wells in the sample well plate 10 contain samples, by separately setting the two driving motors, the Raman head 4 and the sample well plate 10 can be moved to the designated positions for detection, which can effectively improve the detection efficiency without having to scan all the wells in the sample multi-well plate in sequence.

[0101] As Figures 1 - 5 andFigures 11 - 12 As shown, in some embodiments, the motion platform 5 of the present invention further includes a placement table 507 on which the sample well plate 10 can be placed. The placement table 507 is arranged on the slider 504 of the longitudinal moving member 502. The placement table 507 is mounted on the slider 504 by bolts, and a limiting groove is provided at the top of the placement table 507 to limit the sample well plate 10.

[0102] The sample well plate 10 includes a well plate base 1001, above which a sample support frame 1002 is provided. A number of sample well holes are equidistantly arranged on the sample support frame 1002. Anti-slip limiting components 1003 are symmetrically arranged on the side of the well plate base 1001 with the axis of the well plate base 1001 as the center, for restricting the well plate base 1001 on the placement table 507 to prevent the well plate base 1001 from shifting under the action of inertia when the placement table 507 moves.

[0103] The well plate base 1001 and the sample support frame 1002 cooperate to increase the overall height of the sample well plate 10, and the provided sample well holes are used to limit the samples, so that the samples can be placed in the sample well holes or the test tubes can be supported and limited through the sample well holes. The gap of each sample well hole is set with corresponding coordinate values in the data logic of the Raman spectroscopy detection device and the motion platform 5. After each detection by the Raman spectroscopy detection device, coordinate information is marked after the sample information to facilitate the production of detection forms and clarify the Raman spectra of each sample, avoiding data confusion.

[0104] The sample well holes are bottom-sealed holes or through holes. When the sample well holes are sealed holes, the samples to be detected can be directly dropped into the sample well holes for detection, improving the convenience of detection. By setting the sample well holes as through holes, the depth of the holes can be increased, facilitating the insertion of longer test tubes into the sample well holes, reducing the time and steps for transferring samples, and improving the convenience and flexibility of detection.

[0105] The anti-slip limiting component 1003 includes an elastic side strip. The elastic side strip is bow-shaped, and there is a gap between the inner wall of the elastic side strip and the outer surface of the cavity plate base 1001. At the same time, a limiting groove adapted to the bottom cross-section of the cavity plate base 1001 is provided at the top of the placement table 507. When the cavity plate base 1001 is placed in the limiting groove at the top of the placement table 507, the provided limiting groove and the elastic side strip cooperate to position the cavity plate base 1001. The elastic side strip has elasticity. After the sample cavity plate 10 is placed inside the limiting groove, the outer surface of the elastic side strip abuts against the inner wall of the limiting groove due to the elasticity of the elastic side strip, thereby further improving the stability of the sample cavity plate 10 and preventing the sample cavity plate 10 from shaking slightly in the limiting groove. The outer surface of the elastic side strip extends beyond the outer surface of the sample support frame 1002. When the cavity plate base 1001 is placed in the limiting groove, the protruding elastic side strip can better abut against the inner wall of the limiting groove, increasing the contact area and thus enhancing the stability of the limit. The cavity plate base 1001 is a sheet-shaped frame structure, and the projected area of the cavity plate base 1001 is larger than the projected area of the sample support frame 1002. The sheet-shaped frame structure of the cavity plate base 1001 can make the bottom of the sample support frame 1002 suspended, which is used to increase the depth of placing the test tube and improve the stability of placing the test tube.

[0106] As Figure 3 shown, in some embodiments, the Raman spectroscopy detection device of the present invention further includes a lower computer 6 and an interface board 7. The laser generator 2, the spectrometer 3, the motion platform 5, and the lower computer 6 all perform signal interaction and power supply through the interface board 7. The interface board 7 is connected to an external power supply, and a switch is provided at the connection between the interface board 7 and the external power supply to control the startup and shutdown of the device.

[0107] It should be noted that a control core is welded on the interface board 7, and the control core can control the movement of the two driving components 505 through a logic program.

[0108] Signals can be interacted between the spectrometer 3 and the lower computer 6. The lower computer 6 can interact with an external upper computer. The upper computer can set parameters for the spectrometer 3 and read the detection results of the spectrometer 3, and control parameters such as the laser emission of the laser generator 2 and the working mode of the motion platform 5 through the signal relay of the lower computer 6.

[0109] As Figure 2As shown, in some embodiments, the Raman head 4 of the present invention is respectively connected to the laser generator 2 and the spectrometer 3 through optical fibers. The laser generated by the laser generator 2 enters the Raman head 4 through the optical fiber and is emitted towards the sample. Subsequently, after the Raman head 4 receives the laser reflected by the sample, it is transmitted to the spectrometer 3 through the optical fiber for analysis. The optical fiber reserves a length that can move with the Raman head 4 to avoid breakage of the optical fiber caused by excessive pulling during the translation of the Raman head 4. It should be noted that during the process of optical fiber wiring, the optical fiber should be bent as little as possible to reduce optical attenuation, improve the transmission efficiency of the optical fiber and the accuracy of information.

[0110] As Figure 2 and Figures 13 - 14 As shown, in some embodiments, the two optical fibers connecting the laser generator 2 and the spectrometer 3 of the present invention are parallel. A protective tube is commonly sleeved on the outer surfaces of the two parallel optical fibers. The protective tube is a flexible hose and has extensibility. The bare fiber of the optical fiber is prone to breakage. In order to avoid the problem of optical fiber breakage during the repeated movement of the Raman head 4, a protective tube is provided to increase the strength of the optical fiber. And the bending angle of the optical fiber is restricted by the protective tube to reduce optical attenuation and avoid fatigue breakage of the optical fiber.

[0111] The protective tube forms an optical path protection mechanism 11. The optical path protection mechanism 11 includes a sleeve 1101 and a branch protection sleeve 1102. The sleeve 1101 is used to provide the outermost layer of protection for the optical fiber, while the branch protection sleeve 1102 is used to provide the inner layer of protection for the optical fiber. Through the sleeve 1101, the optical fiber can be connected to the Raman head 4 at a relatively gentle angle. The sleeve 1101 can be bent and swung, so that when the Raman head 4 is driven to move by the moving platform 5, the sleeve 1101 can swing with the swing of the Raman head 4. At this time, due to the traction of the sleeve 1101, the turning radius of the optical fiber inside it is restricted and cannot generate too small an angle, avoiding optical fiber breakage and a large increase in optical attenuation. One end of the sleeve 1101 is provided with a Raman head access port 1103. The Raman head access port 1103 is used to connect to the upper end of the Raman head 4, so that the laser emitted by the laser generator 2 inside the Raman spectrometer main body can enter the inside of the Raman head 4, and the reflected laser can enter the spectrometer 3 inside the Raman spectrometer main body through the Raman head 4. The other end of the sleeve 1101 is provided with a protective tube fixing head 1104. The protective tube fixing head 1104 is used to fix the other end of the sleeve 1101 on the optical fiber outlet 108 to improve the stability of the optical fiber. The protective tube fixing head 1104 is installed on the central axis of the Raman spectrometer main body, so that the maximum swing stroke of the sleeve 1101 left and right is equal.

[0112] There are two branch protection sleeves 1102, which are used to protect the optical fibers connected to the laser generator 2 and the spectrometer 3 respectively. Each branch protection sleeve 1102 penetrates from one end of the protection tube fixing head 1104 to the end of the sleeve 1101 and extends into the Raman head access port 1103. After the two optical fibers are connected from the laser generator 2 and the spectrometer 3, the Raman head 4 is connected to realize the emission of laser light and the recovery of reflected light. The outer surface of the protection tube fixing head 1104 is provided with a circular limiting groove, and the protection tube fixing head 1104 is fixed on the optical fiber outlet 108 through the limiting groove. When installing and fixing the optical path protection mechanism 11, the rubber protection tube fixing head 1104 can be deformed by squeezing the protection tube fixing head 1104 to pass through the optical fiber outlet 108 opened on the Raman spectrometer main body for installation. When the pressure on the protection tube fixing head 1104 is lost, the limiting groove will be fixed in the optical fiber outlet 108 of the Raman spectrometer main body. The installation in a detachable manner can improve the convenience of optical fiber maintenance and replacement. Both ends of the branch protection sleeve 1102 are provided with ceramic flange heads, and the ceramic flange heads are ceramic optical fiber flange plugs.

[0113] The optical path protection mechanism 11 further includes an included angle fixing device 12, and the included angle fixing device 12 is used to clamp and limit the branch protection sleeve 1102. When the Raman head 4 is driven by the moving platform 5 to move, the sleeve 1101 will swing with the movement of the Raman head 4, resulting in the vibration of the optical fiber. The vibrating optical fiber is likely to cause the connection between the ceramic flange head and the laser generator 2 and the spectrometer 3 to become loose. Therefore, by setting the included angle fixing device 12 to limit the branch protection sleeve 1102, the vibration of the optical fiber is reduced. At the same time, the access angle between the branch protection sleeve 1102 and the laser generator 2 and the spectrometer 3 can also be changed by fixing the branch protection sleeve 1102 by the included angle fixing device 12, avoiding the increase of optical loss caused by a small bend and affecting the detection result.

[0114] As Figures 5 - 6 、 Figures 8 - 10 shown, in some embodiments, the Raman spectroscopy detection device of the present invention further includes a housing 8, and the housing 8 is used to protect the entire device and the operator. It prevents the operator from accidentally touching the moving parts of the device and getting injured and isolates the laser rays to protect the eyesight of the operator. At the same time, the housing 8 can also improve the aesthetics of the device. The housing 8 is provided with a hatch 801 that is adapted to the position of the placement table 507. The provided hatch 801 is used to place the sample well plate 10 on the placement table 507. An air inlet 802 and an air outlet 803 are respectively provided on the housing 8 to enable air circulation inside the device to achieve the effect of dissipating heat from the device. An active heat dissipation device 9 is provided at the air outlet 803 on the support mechanism 1, and the active heat dissipation device 9 is used to actively increase the speed of air flow and further improve the heat dissipation performance of the device.

[0115] The housing 8 includes a bottom housing assembly 81 and an upper housing assembly 82. The bottom housing assembly 81 and the upper housing assembly 82 are connected to each other to enclose a space for installing the Raman detection spectrometer, so that the Raman spectroscopy detection device performs detection in a closed device state, reducing the influence of external air and dust on the detection results.

[0116] Specifically, the bottom housing assembly 81 includes a bottom housing support platform 811. On both sides of the inner bottom of the bottom housing support platform 811, a number of first connecting columns 812 are provided. The axis of the first connecting columns 812 is set as a threaded hole, and the threaded hole penetrates through to the bottom of the bottom housing support platform 811.

[0117] The upper housing assembly 82 includes a cover 821. Transparent cover plates 822 are provided at both ends of the cover 821. When performing Raman spectroscopy detection, the operator can observe the detection situation inside the housing 8 through the transparent cover plates 822, improving the convenience of use. The transparent cover plates 822 are colored light-transmitting plates, which are used to filter the laser radiation light when observing the sample detection progress conveniently, so as to protect the eyesight of the user. On the inner top of the cover 821, second connecting columns 823 that are adapted to the number and position of the first connecting columns 812 are provided. Bolts passing through the first connecting columns 812 from the bottom of the bottom housing support platform 811 extend into the interior of the second connecting columns 823, and the bottom housing support platform 811 and the cover 821 can be connected together to form a complete housing protective cover.

[0118] Button mounting holes are provided on the side of the bottom housing support platform 811, and the power supply control button and the setting button of the Raman spectroscopy detection device are led out through the button mounting holes to facilitate the operation of the user. Indicator mounting holes are provided on the side of the hatch 801, and the indicator light for displaying the working state of the device and the control button for controlling the opening and closing of the hatch door 804 by driving the moving platform 5 are arranged here to facilitate the control of the hatch door 804.

[0119] An upper air outlet 803 is provided on the top of the cover 821. The cooperation of the upper heat dissipation holes and the bottom heat dissipation holes can form a complete air circulation channel. Thus, cold air enters from one of them and hot air is discharged from the other to form a cycle, improving the heat dissipation efficiency.

[0120] A hatch door 804 is hinged at the hatch 801. The purpose of setting the hatch door 804 is to improve the sealing performance inside the device and reduce the possibility of the sample being disturbed during the Raman detection process.

[0121] The hatch door 804 includes a sealing cover door 8041. A hinge seat 8042 is provided at the edge of the bottom of the sealing cover door 8041, and a connecting shaft 8043 penetrates through the axis of the hinge seat 8042. The connecting shaft 8043 is connected to the hatch 801 on the bottom housing assembly 81 so that the sealing cover door 8041 can rotate radially along the connecting shaft 8043.

[0122] With the above technical solution, when the sealing cover door 8041 is subjected to an outward thrust, since the bottom hinge seat 8042 and the connecting shaft 8043 of the sealing cover door 8041 are hinged to the bottom shell assembly 81, the sealing cover door 8041 will rotate about the connecting shaft 8043 as the axis, exposing the hatch 801 on the bottom shell assembly 81, facilitating the placement and removal of samples.

[0123] A closing door torsion spring 8044 is arranged on the connecting shaft 8043 to provide the resilient force for the sealing cover door 8041 to rebound. The resilient force provided by the closing door torsion spring 8044 can pull the sealing cover door 8041 to close the hatch 801. When the thrust on the sealing cover door 8041 disappears, the sealing cover door 8041 will gradually and automatically close the hatch 801 under the action of the closing door torsion spring 8044 without additional operation by personnel.

[0124] One end of the closing door torsion spring 8044 abuts against the inner wall of the sealing cover door 8041, and the other end of the closing door torsion spring 8044 abuts against the bottom of the bottom shell assembly 81. During installation, the closing door torsion spring 8044 is limited to prevent it from shifting due to force. At the same time, in the natural deflected state, the closing door torsion spring 8044 can drive the sealing cover door 8041 to be in a normally closed state. After the closing door torsion spring 8044 is compressed, it will always exert a resilient force on the sealing cover door 8041 and drive the sealing cover door 8041 back to the closed state after the pressure disappears.

[0125] A torsion spring limit buckle 8045 is arranged on the side of the sealing cover door 8041 facing the hatch 801. The torsion spring limit buckle 8045 is used to fix the end of the closing door torsion spring 8044. In the natural deflected state of the closing door torsion spring 8044, the end of the closing door torsion spring 8044 cooperates with the torsion spring limit buckle 8045 to exert a resetting force on the sealing cover door 8041. And the torsion spring limit buckle 8045 will limit the end of the closing door torsion spring 8044 to prevent the closing door torsion spring 8044 from sliding on the outer surface of the connecting shaft 8043, resulting in non-central force on the sealing cover door 8041.

[0126] Reinforcing ribs 8046 are arranged on both sides of the side of the sealing cover door 8041 facing the hatch 801. The reinforcing ribs 8046 can effectively increase the structural strength of the sealing cover door 8041. At the same time, both of the two reinforcing ribs 8046 can interact with the triggering device for pushing the sealing cover door 8041 to push the sealing cover door 8041 to rotate and open the hatch 801, so as to prevent the triggering device for pushing the sealing cover door 8041 from directly contacting the inside of the sealing cover door 8041 and causing damage to the relatively weak sealing cover door 8041.

[0127] Each reinforcing rib 8046 includes a contact frame, which is arranged along the inside of the sealing cover door 8041, and the side of the contact frame facing the triggering mechanism is made of wear-resistant material. A secondary rib plate is arranged on the side of the contact frame, and the secondary rib plate can support the contact frame. The purpose of setting the secondary rib plate is to further enhance the strength of the sealing cover door 8041 and the contact frame. Because the contact frame will directly receive the pressure from the triggering mechanism, which may cause the contact frame to deform easily. At the same time, the connection between the contact frame and the sealing cover door 8041 is a linear connection, and the stress points are relatively concentrated.

[0128] The active heat dissipation device 9 includes a heat dissipation fan 901 installed on the inner top of the sealing cover, and the heat dissipation fan 901 penetrates through the top of the sealing cover. When the heat dissipation fan 901 is powered on and working, it will accelerate the air flow in the horizontal equipment box 104, thereby increasing the heat dissipation of the equipment inside the horizontal equipment box 104. At this time, the air flow will circulate throughout the device through the vertical ventilation wiring groove, the wire hole groove, and the optical fiber outlet 108. An air exchange groove is provided at the upper part of the rear cover, and the air exchange groove is communicated with the inside of the vertical equipment box 103. When the heat dissipation fan 901 drives the air to flow, part of the air will interact with the outside through the air exchange groove, thereby further improving the heat dissipation performance of the device. A bottom ventilation groove is provided at the inner bottom of the support base 101 in the vertical equipment box 103. The provided bottom ventilation groove can cooperate with the air exchange groove to form a channel for air circulation. Air can enter the inside of the vertical equipment box 103 from the bottom ventilation groove or the air exchange groove and flow out of the inside of the vertical equipment box 103 from the bottom ventilation groove or the air exchange groove to take away the heat generated during the operation of the equipment. A heat exchange hole is provided at the bottom of the back of the sealing cover, and the heat exchange hole is communicated with the wire hole groove, so that while the vertical equipment box 103 and the horizontal equipment box 104 are communicated, the vertical equipment box 103 and the horizontal equipment box 104 can also be communicated with the outside through the heat exchange hole to improve the heat dissipation effect.

[0129] As Figure 5 shown, in some embodiments, the storage table 507 of the present invention can extend from the storage port 801 to the outside of the housing 8. During use, the longitudinal moving member 502 will drive the storage table 507 to move towards the storage port 801, and make the limit groove on the storage table 507 completely exposed outside the housing 8 to facilitate the placement and removal of the sample well plate 10. The operation of the storage table 507 entering and exiting the storage port 801 is performed through the control switch on the side of the storage port 801, and the control switch is connected to the interface board 7.

[0130] The specific use process of the present invention is as follows:

[0131] Drive the storage table 507 to push open the storage door 804 through the switch, so that the storage table 507 is completely exposed;

[0132] Steadily place the sample well plate 10 with samples on the placement table 507, and then drive the placement table 507 back into the interior of the housing 8 through the switch again. At this time, the chamber door 804 closes under the action of the closing torsion spring 8044;

[0133] Set the parameters of the laser generator 2, the spectrometer 3, and the motion platform 5 respectively through the host computer, and start the laser generator 2, the spectrometer 3, and the motion platform 5 respectively, so that the Raman head 4 and the placement table 507 move, and emit laser light to the sample and receive the reflected laser light through the Raman head 4;

[0134] The reflected laser signal generates a Raman spectrum through the spectrometer 3 and then is transmitted to the host computer;

[0135] After the Raman detection of the sample is completed, drive the placement table 507 to push open the chamber door 804 through the switch again, so that the placement table 507 is completely exposed, take out the sample well plate 10 to end the detection or replace the new sample well plate 10 to continue the detection;

[0136] During the process of Raman detection, the active heat dissipation device 9 actively intervenes in the work to dissipate heat inside the device.

[0137] In summary, the Raman spectrum detection device with high-efficiency detection function of the present invention sets a lateral moving member 501 and a longitudinal moving member 502 on the support mechanism 1 respectively, and makes the lateral moving member 501 and the longitudinal moving member 502 be vertically distributed in a top view state, and drives the Raman head 4 to move through the lateral moving member 501 respectively, and the longitudinal moving member 502 drives the placement table 507 to move, so that the holes of the sample well plate 10 placed on the placement table 507 can be perpendicular and collinear with the laser emitted by the Raman head 4 for Raman detection, realizing batch and rapid Raman detection of samples and improving the efficiency of Raman detection.

[0138] By setting a lower computer 6 and an interface board 7 on the support mechanism 1, connecting the spectrometer 3 to the lower computer 6, and at the same time, connecting the laser generator 2 and the motion platform 5 to the interface board 7 respectively for power supply and command interaction, and connecting the lower computer 6 to the interface board 7 and the host computer respectively, so that the host computer can interact and control the device through the lower computer 6, improving the convenience and expandability of device control.

[0139] The entire device is protected by setting up a housing 8, and a hatch 801 adapted to the position of the placement table 507 is opened on the housing 8 for the placement table 507 to enter and exit. At the same time, a hatch door 804 is provided on the hatch 801 to close the hatch 801. During use, the placement table 507 pushes open the hatch door 804 to facilitate the placement of the sample well plate 10. During the detection process, the placement table 507 drives the well plate into the interior of the housing 8 to ensure the cleanliness of the sample plate, reduce interference during the sample detection process, and avoid harm to the human body caused by laser radiation, achieving the effect of improving safety and the accuracy of sample detection.

[0140] Therefore, the present invention effectively overcomes various drawbacks in the prior art and has high industrial utilization value.

[0141] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
