[0002] In the application of spectrum automatic detection in the modern market industry, with the increasing demands of customers, including new requirements such as improving efficiency and reducing costs, the requirements for integrating spectrum automatic detection equipment into automated production are also getting higher and higher. In the existing spectrum automatic detection field, independent X-ray fluorescence spectrum equipment is still mainly used, and there is a lack of mechanisms or devices for automated assembly line production, especially for the assembly line transportation mechanisms or devices of flat or flat structures in some 3C products. Therefore, it is necessary to find some mechanisms or devices that can improve production efficiency. Summary of the invention

[0003] In view of this, it is necessary to overcome at least one of the above-mentioned defects in the prior art. The present invention provides an automatic assembly line energy dispersive X-ray fluorescence spectrum array scanning analysis method, which can effectively solve the related problems, including: The left automatic sample feeding docking device / right automatic sample feeding docking device delivers the array samples to the sample transmission positioning detection mechanism in the X-ray fluorescence spectrum array scanning analysis device through the corresponding first transmission mechanism and the second transmission mechanism, and the Z-axis energy dispersion X-ray fluorescence spectrometer high-efficiency dual-optical path system above detects and analyzes the array samples; The sample transmission positioning detection mechanism performs XY axis movement through the XY axis automatic adjustment device and cooperates with the Z axis movement mechanism of the dual optical path system to position the array sample. At the same time, the host lifting mechanism clamps or fixes the array sample and cooperates with the fixed transmission mechanism and the mobile transmission mechanism on the transmission positioning detection mechanism to form side positioning on both sides. After the side positioning is completed, the array sample is set at the lower side of the dual optical path system, the first optical path module in the dual optical path system is fixed, and the second optical path module, the third optical path module and the nth optical path module matched with the first optical path module are moved to form the first optical path module corresponding to the starting sample, the second optical path module corresponding to the mth sample, the third optical path module corresponding to the 2*(m-1) sample, and so on. The nth optical path module corresponds to the (n-1)*(m-1) sample. When all optical path modules correspond to the corresponding samples, the detection and analysis function of the dual optical path system is started to perform detection and analysis.

[0004] The method involves equipment including: a left automatic sampling docking device and a right automatic sampling docking device on both sides, an X-ray fluorescence spectrum array scanning and analysis device located between the left automatic sampling docking device and the right automatic sampling docking device, the X-ray fluorescence spectrum array scanning and analysis device including an XY-axis automatic adjustment device and a Z-axis energy dispersion X-ray fluorescence spectrometer high-efficiency dual-light path system located above the XY-axis automatic adjustment device, and an energy dispersion X-ray fluorescence spectrometer water cooling pipeline with multiple safety protections connected to an X-ray source in the high-efficiency dual-light path system and used for cooling; The XY axis automatic adjustment device comprises an X adjustment mechanism for adjustment on the X axis and a Y adjustment mechanism for adjustment on the Y axis, wherein the X adjustment mechanism is arranged on the Y adjustment mechanism, a sample transmission positioning detection mechanism is installed on the X adjustment mechanism, and a protective cover lifting mechanism including a protective cover is also installed on the X adjustment mechanism, wherein the protective cover is a barrel-shaped structure without upper and lower covers, and the XY axis automatic adjustment device is arranged in the barrel-shaped structure; The energy dispersive X-ray fluorescence spectrometer high-efficiency dual-optical path system includes: an optical path base plate, a first optical path module fixedly mounted on the optical path base plate, a second optical path module, a third optical path module, and up to the nth optical path module mounted on a sliding component on the optical path base plate and matching the fixed optical path module, an integrated light gate collimating filter switching module mounted under the first optical path module and the second optical path module, the third optical path module, and up to the nth optical path module, and a movable adjustment module corresponding to the second optical path module, the third optical path module, and up to the nth optical path module one by one and used to adjust the second optical path module, the third optical path module, and up to the nth optical path module and the first optical path module and the distance between them.

[0005] According to the prior art described in the background of the present invention, in the existing spectral automatic detection field, independent X-ray fluorescence spectroscopy equipment is mainly used, and there is a lack of automated assembly line production mechanisms or devices, especially for the assembly line transportation mechanisms or devices of the plane or flat structure in some 3C products; and the automatic assembly line energy dispersion X-ray fluorescence spectrum array scanning analysis method disclosed in the present invention, through the left and right automatic sample feeding docking devices (the two devices can be exactly the same, which is convenient for adjusting the production process and reducing the overall production cost) to transport products to the middle X-ray fluorescence spectrum array scanning analysis device, and perform array detection, at the same time, the product optical path system is optimized from the actual application of the product, and multiple optical path modules are arranged, one path is a fixed mode, and the other paths can adjust their displacement through the mobile module, and the integrated light gate, collimation, filter switching component optical path accessories are optimized and configured, and the test unit effectively adjusts the displacement of the movable optical path according to the algorithm calculation according to the samples of different specifications and sizes, so as to realize a high-efficiency and high-performance optical path system, thereby meeting the testing needs of different products, and can simultaneously meet the requirements of accuracy and efficiency of the testing process, and is applied to industries related to the RoHS directive, the electronic product industry, the integrated circuit industry and other industries with higher requirements for efficiency and accuracy.

[0006] Among them, the scanning detection method carried out according to the algorithm for calculating the effective adjustment of the displacement of the movable optical path and other processes can be implemented by the following method: The sample array is arranged on the lower side of the optical path bottom plate. The distance between the fixed first optical path module and the plurality of second optical path modules is designed in advance or adjusted according to the sample array to form the distance S2 between the first optical path module and the second optical path module, the distance S3 between the second optical path module and the third optical path module, until the distance Sn between the (n - 1)th optical path module and the nth optical path module, and the first optical path module corresponds to the starting sample in the sample array, the second optical path module corresponds to the mth sample determined according to the distance S2, until the nth optical path module corresponds to the sample obtained by arranging and combining the (n - 1)*(m - 1) samples determined according to the distance Sn for detection. Then, the driving part is used to drive the optical path bottom plate for array scanning detection; The number of movable optical path modules can be determined according to the width of the sample array. When the width of the sample array is small, only two sets of optical path modules, such as the first optical path module and the second optical path module, can be used. To improve the efficiency, the distance between the first optical path module and the second optical path module can be adjusted to half of the width of the sample array (the sample array is i*j). At the start of detection, the detection point of the first optical path module is at the first starting point (1,1) of the sample array, and the detection starting point of the second optical path module is at the sample (i / 2,j). If i is odd, the detection starting point of the second optical path module is at ((i + 1) / 2,j). In this way, the efficiency can be doubled; When the width of the sample array is large, n>2 movable optical path modules can be used. The method is the same as the method when n = 2, and the efficiency can be increased by n times. If the sample array is larger, the optical path modules on the optical path bottom plate can be made into an array-type optical path, and its efficiency can be increased more. At the same time, due to the adoption of a dual-path detection component, the detection accuracy can be further improved; In the detection method, the sample can be fixed and the optical path moves in the XY axes, even including the Z axis movement, or the optical path is only responsible for the Z axis movement and the sample moves in the XY axes, thereby forming a three-dimensional movement between the optical path and the sample, and further improving the overall efficiency.

[0007] In addition, according to the automatic pipeline energy dispersive X-ray fluorescence spectrometry array scanning analysis method disclosed in the present invention, the following additional technical features are also provided: Furthermore, the left automatic sampling docking device and the right automatic sampling docking device include a base plate, a first conveying mechanism and a second conveying mechanism, the first conveying mechanism and the second conveying mechanism correspond to each other, the first conveying mechanism is fixedly mounted on the base plate, the second conveying mechanism is mounted on the base plate through a sliding mechanism, and a lifting mechanism for lifting the sample; the first conveying mechanism includes a supporting component mounted on the base plate to play an overall supporting role, a conveying wheel and an adjusting wheel mounted on the supporting component, and a conveyor belt mounted on the conveying wheel and the adjusting wheel, a driving component mounted on the supporting component, and a driving wheel mounted on the driving shaft of the driving component; the second conveying structure includes a supporting component mounted on the sliding mechanism A supporting component that plays an overall supporting role, a transmission wheel and an adjusting wheel installed on the supporting component, and a conveyor belt installed on the transmission wheel and the adjusting wheel, a driving component installed on the supporting component, and a driving wheel installed on the driving shaft of the driving component; the lifting mechanism includes a clamping claw at the front end for clamping the sample, and a lifting component at the rear end for driving the clamping claw to lift up, and left and right automatic sampling docking devices. The automatic sampling docking devices arranged on the left and right sides of the detection host can realize rapid assembly line transportation of planar structure products. At the same time, the lifting mechanism is used to ensure that the planar structure product can be lifted off the conveyor belt or stopped at a fixed position when the equipment is in the state of sampling stop and the power transmission mechanism is in continuous operation, thereby ensuring the safety of the product.

[0008] Specific process: When the external assembly line transports samples to the automatic sampling docking device, the transmission wheel and the transmission belt extend out of the boundary of the horizontal plate. At the same time, the outer diameter of the transmission wheel is lower than the outer edge of the conveyor belt, so the sample is smoothly transferred from here. The positions of the second conveying mechanism and the first conveying mechanism are adjusted to realize the transmission of products of different widths. The tension of the conveyor belt is adjusted by the up and down adjustment structure and the left and right adjustment structure. The problems caused by the excessive length of the conveyor belt can also be adjusted. At the same time, the lifting mechanism is used to ensure that the planar structure product can be lifted off the conveyor belt or stopped at a fixed position when the equipment is in the state of sampling stop and the power transmission mechanism is in continuous work, so as to ensure the safety of the product. The clamping jaws and the side are provided with anti-static and wear-resistant soft materials to avoid scratches on the product surface.

[0009] Furthermore, the lifting component is a cylinder, and the clamp is installed at the end of the cylinder. There can be two cylinders, distributed on the left and right sides, and driven at the same time to ensure the stability of the product's posture. It can also be one. When it is one, it is set on the side where the sample enters the detection host. When the sample inside the monitoring host is in the detection process, the conveyor belt is still rotating. At this time, the lifting component rises, and the front clamp extends to block the sample. The lifting component can lift the sample away from the conveyor belt, or it can not lift the sample away from the conveyor belt, but only block the sample from moving forward.

[0010] Furthermore, the lifting component is a rotating motor, and the clamping jaw is installed on a screw structure connected to the motor, or the lifting component is a linear motor, and the clamping jaw is installed on the linear motion structure of the linear motor. Using a motor can make the lifting action more stable.

[0011] Furthermore, the sliding mechanism includes a slide rail provided on the bottom plate and a slider installed on the slide rail. The support component of the second conveying mechanism is installed on the slider. In this way, the distance between the first conveying mechanism and the second conveying mechanism can be adjusted through automatic control or manual control to adapt to the product conveying processes of different widths.

[0012] Furthermore, the support component includes a vertical vertical plate and a horizontal plate installed on the vertical plate. The conveying wheels are arranged on both sides of the horizontal plate and inside the conveyor belt, and the adjusting wheels are arranged on the horizontal plate at a position lower than the conveying wheels and outside the conveyor belt. The driving component is a motor, and the motor is installed on the horizontal plate through a motor fixing plate. The driving wheel is arranged on the motor driving shaft and inside the conveyor belt. The support components of the two conveying mechanisms can be the same or different. The vertical plate can be designed according to requirements when installed on the sliding mechanism or on the bottom plate. Similarly, the support component can also be an integrally formed structure, and the horizontal plate can be designed in the same way.

[0013] Furthermore, an up-and-down adjustment structure for adjusting the up-and-down movement of the motor is provided on the horizontal plate. The up-and-down adjustment structure is an adjustment groove or an adjustment hole. By moving the fastener on the motor fixing plate up and down in the adjustment groove or adjustment hole and locking it, the up-and-down positions of the motor and the driving wheel can be adjusted to adjust the tension of the conveyor belt. The adjustment groove can perform continuous adjustment of the position, and the adjustment hole can perform discrete adjustment.

[0014] Furthermore, a left-and-right adjustment structure for adjusting the left-and-right movement of the adjusting wheel is provided on the horizontal plate. The left-and-right adjustment structure is an adjustment groove or an adjustment hole. By locking the lateral position of the adjusting wheel in the adjustment groove or adjustment hole, the tension of the conveyor belt can be adjusted, and the problems caused by the excessive length of the conveyor belt can also be adjusted.

[0015] The horizontal plate can have both a left-and-right adjustment structure and an up-and-down adjustment structure at the same time, or can be set separately.

[0016] Furthermore, the conveying wheels protrude beyond the left and right boundaries of the horizontal plate. Since the overall device also needs to be docked with an external assembly line, the conveying wheels with the conveyor belt extending beyond the left and right boundaries of the horizontal plate can better fill the possible gaps between itself and the external assembly line, making the conveying more stable.

[0017] Furthermore, the edge of the conveyor wheel is lower than the outer surface of the conveyor belt, so that the product can be in full contact with the outer surface of the conveyor belt, ensuring the smooth transportation of the product.

[0018] The device further includes an external bracket and an upper plate and other panels arranged on the external bracket. The upper plate has holes for the protruding clamping jaws. The conveyor belt and the cross plate both protrude from the upper plate, and the driving wheel protrudes from the outer boundary of the cross plate and also protrudes from the outer boundary of the external bracket. The outer boundary of the cross plate can be the same as the front and rear boundaries of the external bracket or can protrude from the boundary of the external bracket.

[0019] Furthermore, side edges for restricting the left - right movement of the sample are installed on the cross plate. The conveyor belt carries the sample to move back and forth. The side edges ensure that the sample does not change its position in the left - right directions. At the same time, the side edges are made of a soft material to avoid damage to the surface of the sample. Preferably, they are of a soft organic material structure.

[0020] Furthermore, the sample transfer positioning and detection mechanism includes an X-adjustment sliding bottom plate installed on the X-adjustment mechanism, a fixed transfer mechanism and a mobile transfer mechanism. The fixed transfer mechanism and the mobile transfer mechanism correspond to each other. The fixed transfer mechanism is fixedly installed on the X-adjustment sliding bottom plate, and the mobile transfer mechanism is installed on the X-adjustment sliding bottom plate through a main machine sliding mechanism, as well as a main machine lifting mechanism for lifting or blocking the movement of the sample; the fixed transfer mechanism includes a main machine support component installed on the X-adjustment sliding bottom plate for overall support, a main machine transfer wheel and a main machine adjustment wheel installed on the main machine support component, and a conveyor belt cooperatively installed with the main machine transfer wheel and the main machine adjustment wheel, a main machine drive component installed on the main machine support component, and a main machine drive wheel installed on the drive shaft of the main machine drive component; the mobile transfer mechanism includes a main machine support component installed on the main machine sliding mechanism for overall support, a main machine transfer wheel and a main machine adjustment wheel installed on the main machine support component, and a conveyor belt cooperatively installed with the main machine transfer wheel and the main machine adjustment wheel, a main machine drive component installed on the main machine support component, and a main machine drive wheel installed on the drive shaft of the main machine drive component; the main machine lifting mechanism includes a main machine jaw at the front end for clamping the sample, and a main machine lifting component at the rear end for driving the main machine jaw to lift; the main machine support component includes a vertical main machine vertical plate and a main machine horizontal plate installed on the vertical plate. The main machine transfer wheels are arranged on both sides of the main machine horizontal plate and inside the main machine conveyor belt. The main machine adjustment wheels are arranged on the main machine horizontal plate at a position lower than the main machine transfer wheels and outside the main machine conveyor belt. The main machine drive component is a motor, and the main machine drive component is installed on the main machine horizontal plate through a main machine motor fixing plate. The main machine drive wheel is arranged on the drive shaft of the main machine motor and inside the main machine conveyor belt; the XY-axis automatic adjustment device realizes the XY-axis position adjustment of flat-structured products quickly through the XY-axis automatic adjustment device arranged inside the detection main machine, and uses the main machine lifting mechanism to ensure that when the equipment is in continuous operation of the transfer mechanism, the flat-structured products can be lifted off the conveyor belt or stopped at a fixed position, ensuring the safety of the products. At the same time, the sample clamping component is also used to move from the lateral direction (the direction perpendicular to the movement direction) to the side of the fixed transfer mechanism or the mobile transfer mechanism, thereby fixing the sample horizontally and ensuring the accurate position of the sample. And when the X-ray device is working, the protective cover lifting mechanism raises the protective cover to prevent the leakage of the protective cover. At the same time, the lifting component of the protective cover lifting mechanism is in the normally open state, that is, when a machine failure occurs, the protective cover is in the raised state to avoid the leakage of X-rays.

[0021] Specific process: the X-adjustment mechanism and the Y-adjustment mechanism move together or separately, so that the mainframe conveyor belt part (mainly the mainframe conveyor wheel carrying the outer edge of the mainframe conveyor belt) extends out of the detection mainframe, and cooperates with the external automatic sample feeding docking device. The automatic rest docking device has a conveyor belt and a conveyor wheel with similar structure. The sample is conveyed into the detection mainframe through the mainframe conveyor belt. The X-adjustment mechanism and the Y-adjustment mechanism move together to move the sample to a predetermined position. At the same time, the mainframe lifting mechanism lifts the sample away from the mainframe conveyor belt or lifts it to prevent the sample from moving. At the same time, the clamping jaws and the side cooperate to clamp the sample between the clamping jaws and the side to form a fixed positioning. The X-ray detection equipment located above the XY axis automatic adjustment device inside the detection mainframe adjusts the upper and lower positions, and cooperates with the X-adjustment mechanism and the Y-adjustment mechanism to realize the detection of the sample.

[0022] Furthermore, the XY-axis automatic adjustment device also includes a sample clamping component arranged on the fixed conveying mechanism / mobile conveying mechanism, and the sample clamping component includes a clamping cylinder and a clamping claw. The clamping claw is arranged above the main conveyor belt of the fixed conveying mechanism / the mobile conveying mechanism, and the clamping claw cooperates with the side of the mobile conveying mechanism / the fixed conveying mechanism for limiting the vertical movement direction of the sample. When the sample is transported to the predetermined position through the conveyor belt, before the main host performs detection, the clamping claw moves inward and cooperates with the side to fix the sample in the lateral position to ensure that the position is accurate when the main host detects; the clamping claw is provided with an anti-static soft contact sheet.

[0023] Furthermore, the host lifting component is a cylinder, and the clamping claw is installed at the end of the host lifting component; the cylinder can be two, distributed on the left and right sides, and driven at the same time to ensure the stability of the product posture, or it can be one, and when it is one, it is set on the side where the sample enters the detection host. When the sample inside the monitoring host is in the detection process, the conveyor belt is still rotating. At this time, the lifting component rises, and the front clamping claw extends to block the sample. The lifting component can lift the sample away from the conveyor belt, or it can not lift the sample away from the conveyor belt, but only block the sample from moving forward. or The main engine lifting component is a rotating motor, and the clamp is installed on a screw structure connected to the main engine lifting component, or the main engine lifting component is a linear motor, and the clamp is installed on the linear motion structure of the linear motor. Using a motor can make the lifting action smoother.

[0024] Further, the host sliding mechanism includes a slide rail disposed on the base plate and a slider mounted on the slide rail, and the support member of the mobile transfer mechanism is mounted on the slider. In this way, the distance between the fixed transfer mechanism and the mobile transfer mechanism can be adjusted through automatic control or manual control to adapt to the product transfer processes of different widths.

[0025] Further, the host support member includes a vertical host vertical plate and a host horizontal plate mounted on the vertical plate. The host transfer wheels are disposed on both sides of the host horizontal plate and inside the host conveyor belt. The host adjustment wheels are disposed on the host horizontal plate at a position lower than the host transfer wheels and outside the host conveyor belt. The host drive member is a motor, and the host drive member is mounted on the host horizontal plate through a host motor fixing plate. The host drive wheel is disposed on the host motor drive shaft and inside the host conveyor belt. The support members of the two transfer mechanisms may be the same or different. The vertical plate can be designed according to the need to be disposed on the sliding mechanism of the sample transfer positioning mechanism or on the base plate. Similarly, the support member may also be an integrally formed structure, and the horizontal plate can be designed in the same way.

[0026] Further, a host up-and-down adjustment structure for adjusting the up-and-down movement of the host drive member is disposed on the host horizontal plate. The host up-and-down adjustment structure is an adjustment groove or an adjustment hole. By moving the fastener on the motor fixing plate up and down in the adjustment groove or the adjustment hole and locking it, the up-and-down positions of the motor and the drive wheel can be adjusted to adjust the tension of the conveyor belt. The adjustment groove can perform continuous adjustment of the position, and the adjustment hole can perform discrete adjustment.

[0027] Further, a host left-and-right adjustment structure for adjusting the left-and-right movement of the host adjustment wheel is disposed on the host horizontal plate. The host left-and-right adjustment structure is an adjustment groove or an adjustment hole. By locking the horizontal position of the adjustment wheel of the sample transfer positioning mechanism in the adjustment groove or the adjustment hole, the tension of the conveyor belt can be adjusted, and the problems caused by the excessive length of the conveyor belt can also be adjusted.

[0028] The host horizontal plate may have both a host left-and-right adjustment structure and a host up-and-down adjustment structure at the same time, or may be provided separately.

[0029] Further, the host transfer wheels protrude beyond the left and right boundaries of the host horizontal plate. Since the detection host also needs to be docked with an external assembly line, the host transfer wheels, together with the host conveyor belt, extend beyond the left and right boundaries of the host horizontal plate, which can better compensate for the possible gap between itself and the external assembly line and make the transfer more stable.

[0030] Further, the edge of the main conveyor wheel is lower than the outer surface of the main conveyor belt, so that the product can be in full contact with the outer surface of the main conveyor belt, ensuring the smooth transportation of the product.

[0031] Further, the lifting member is a cylinder, and the protective cover lifting mechanism further includes a limiting member for adjusting the up and down positions of the lifting member.

The sample is installed below the vertical interface, and the inclined interface axially points to the sample; the mobile adjustment module corresponds to the second optical path module, the third optical path module up to the nth optical path module one by one. The mobile adjustment module is connected to the second optical path module, the third optical path module up to the nth optical path module through a connecting member, and drives the second optical path module, the third optical path module up to the nth optical path module to move back and forth to adjust the distance between the first optical path module or the second optical path module, the third optical path module up to the nth optical path module.

[0034] Further, the detector component and the inclined interface are symmetrically distributed around the single-channel X-ray source component and the vertical interface, and are evenly distributed, which can make the overall detection effect more accurate and obtain higher efficiency.

[0035] Further, the angle of the inclined interface is 20 - 70 degrees. The design of the angle not only brings convenience to installation and maintenance, but also has a better effect on the collection of the excitation light.

[0036] Further, the angle of the inclined interface is 30, 45, 50, 60, 70 degrees.

[0037] Further, the detector assembly is mounted on the inclined interface through a detector insulating block, and the X-ray source assembly is mounted on the vertical interface through an optical tube fixing ring.

[0038] Further, a collimator for providing collimation is also provided between the sample and the X-ray source assembly. The collimator is a circular hole for shielding X-rays in non-necessary / non-central regions.

At the same time, it also uses the sample clamping component to move from the lateral direction (the direction perpendicular to the movement direction) to the side of the fixed transfer mechanism or the mobile transfer mechanism, thereby fixing the sample laterally to ensure the accurate position of the sample. And when the X-ray device is working, the protective cover lifting mechanism raises the protective cover to prevent the leakage of the protective cover. At the same time, the lifting component of the protective cover lifting mechanism is in a normally open state, that is, when a machine failure occurs, the protective cover is in a raised state to avoid the leakage of X-rays.

[0088] According to some embodiments of the present invention, a detection method based on the efficient dual optical path system: The sample array is arranged on the lower side of the optical path base plate. The distance between the first optical path module and the plurality of second optical path modules is pre-designed or adjusted according to the sample array to form the distance S2 between the first optical path module and the second optical path module, the distance S3 between the second optical path module and the third optical path module, until the distance Sn between the (n - 1)th optical path module and the nth optical path module, and the first optical path module corresponds to the starting sample in the sample array, the second optical path module corresponds to the mth sample determined according to the distance S2, until the nth optical path module corresponds to the (m + n)th sample pair determined according to the distance Sn for the arranged and combined samples for detection, and then the driving part is used to drive the optical path base plate for array scanning detection, as Figure 9 shown, Figure 9 two optical path modules are used for detection in

[0089] According to the embodiments of the present invention, the number of moving optical path modules can be determined according to the width of the sample array.

To improve the efficiency, the distance between the first optical path module and the second optical path module can be adjusted to half of the width of the sample array (the sample array is i*j). At the beginning of the detection, the detection point of the first optical path module is at the first starting point (1,1) of the sample array, and the detection starting point of the second optical path module is at the sample (i / 2,j). If i is odd, the detection starting point of the second optical path module is at ((i + 1) / 2,j).

[0090] According to the embodiments of the present invention, when the width of the sample array is large, n>2 moving optical path modules can be used. The method is the same as the method when n = 2, and the efficiency can be increased by n times. If the sample array is larger, the optical path modules on the optical path base plate can be made into an array-type optical path, and its efficiency can be increased more.

[0091] In the detection method, the sample can be fixed and the optical path moves in the XY axes, even including the Z axis movement, or the optical path is only responsible for the Z axis movement and the sample moves in the XY axes, thereby forming a three-dimensional movement between the optical path and the sample, further improving the overall efficiency.
