LED has the advantages of small size, long life, low driving voltage, low power consumption, fast response rate, and good shock resistance. It is widely used in signal indication, digital display and other fields.

[0003] A patent application with publication number CN112525884A discloses an ultra-trace Raman spectroscopy detection device, including an ultra-trace detection device combining optical fiber tweezers and Raman spectroscopy. The optical tweezers can capture substances at the single cell level, such as cells, and move them into the V-shaped groove of the Raman detection optical fiber probe under the optical tweezers, so as to efficiently utilize the substance to be tested, improve the collection efficiency of Raman scattered light, and obtain an accurate Raman spectrum.

[0004] In the current prior art, when detecting LED lamps, since the light source of the LED lamp is scattered in all directions when it is divergent, the detection device does not capture the light source completely when detecting the LED lamp, and the detected data is not detailed, which affects the detection effect.

[0005] To this end, the present invention provides a Raman spectrum detection device for LED production. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: a Raman spectrum detection device for LED production described in the present invention comprises a conveyor, a mounting box is symmetrically arranged on the top of the conveyor, a detection box is fixedly installed on the top of two mounting boxes, a light collecting component is arranged inside the detection box, the light collecting component is used to refract and concentrate the light emitted from the bottom of the LED lamp, and plays the role of a concentrated light source, a casual assembly is arranged inside the mounting box, the casual assembly is used to connect and install the detection box with the conveyor, and plays the role of facilitating assembly, and a Raman spectrum detector is arranged inside the detection box;

[0008] During installation, the detection box is placed above the conveyor, and then the installation box is placed on both sides of the conveyor. The detection box and the conveyor are installed and connected through the convenient components in the installation box. The setting of the convenient components facilitates assembly and disassembly. Then, the LED lamp to be detected is placed on the conveyor, and the conveyor drives the LED lamp to move to the bottom of the detection box. Then, the Raman spectrum detector in the detection box captures the light emitted by the LED lamp. At the same time, the light collecting component refracts and concentrates the light emitted from the bottom of the LED lamp, and assists the Raman spectrum detector to capture the scattered light that cannot be captured. Then, the Raman spectrum detector uses the Raman signal excited by the LED light source to obtain the Raman narrowband measurement signal through a bandpass filter and a photodetector with special spectral transmittance, and then reconstructs the Raman spectrum with high spectral resolution through a data post-processing module. Finally, the data is displayed on the display for people to observe and play a detection role.

[0009] Preferably, a placement plate and a limiting plate are fixedly installed on the top of the inner wall of the detection box, a motor is fixedly installed on the top of the placement plate, a plurality of fixing ring rods are fixedly installed on the bottom of the placement plate, a fixing ring is fixedly installed on one end of the plurality of fixing ring rods, the fixing ring is arranged in the middle of the inner wall of the limiting plate, and the Raman spectrum detector is fixedly installed in the fixing ring. During installation, the Raman spectrum detector is arranged in the fixing ring, the Raman spectrum detector is hung on the bottom of the placement plate through the fixing ring rods, and the fixing ring is placed in the middle of the inner wall of the limiting plate, so that the Raman spectrum detector can maintain a stable receiving distance with the LED lamp during detection work, and will not interfere with the motor when driving subsequent process operations, causing any impact.

[0010] Preferably, the output end of the motor is fixedly installed with a shaft disk, the shaft disk is slidably connected to the outer wall of a plurality of fixing ring rods, the bottom of the shaft disk is fixedly installed with a plurality of connecting rods, and the bottom ends of the plurality of connecting rods are fixedly installed with a focusing tube, the focusing tube is slidably connected to the outer wall of the fixing ring, the fixing ring is placed in the middle of the inside of the focusing tube, the focusing tube is slidably connected to the inner wall of the limiting plate, and the inside of the detection box is symmetrically fixedly installed with a frame plate, the outer walls of the two frame plates are fixedly connected to the inner walls of the setting plate and the limiting plate. When the conveyor drives the LED lamp to be placed under the detection box, the motor drives the shaft disk to move downward. When the shaft disk moves downward, the shaft disk drives the focusing tube to move downward through a plurality of connecting rods. When the motor drives the focusing tube to cover the LED lamp, the motor stops operating. At this time, the light collecting component refracts and concentrates the light diverged from the bottom of the LED lamp, so that the Raman spectrum detector can better detect the LED lamp. The LED lamp is covered by the focusing tube, so that when the Raman spectrum detector is detecting, the focusing tube can better prevent the divergence of the LED lamp, thereby limiting the divergence of the light source.

[0011] Preferably, the light collecting component includes a refracting mirror plate, and there are two refracting mirror plates, the outer walls of the two refracting mirror plates are fixedly mounted with a rectangular plate, the top of the rectangular plate is fixedly mounted with a force block, the outer walls of the two frame plates are fixedly mounted with a groove plate, the bottoms of the two rectangular plates are respectively slidably connected to the inner walls of the two groove plates, the outer wall of the shaft disk is symmetrically fixedly mounted with a pressure plate, the bottoms of the two pressure plates are fixedly mounted with an extrusion block, the outer walls of the two extrusion blocks are respectively slidably connected to the outer walls of the two force blocks, when the motor drives the focusing cylinder to move downward toward the LED lamp cover through the shaft disk, the shaft disk also drives the pressure plate to move, and when the pressure plate moves, it drives the extrusion block to move downward, and the extrusion block squeezes the force block when it moves downward. The force block moves, and the force block will drive the rectangular plate to slide out of the groove plate when moving, and the refracting mirror plate on one end of the rectangular plate will slowly extend out. When the two refracting mirror plates on the left and right complete contact through driving, the focusing tube will cover the LED lamp, and the focusing tube will be placed above the two refracting mirror plates, and the LED lamp will be placed between the two. The two refracting mirror plates will form a refractive arc surface under the LED lamp. When the LED lamp is on, the refracting mirror plate refracts the light emitted from the bottom of the LED lamp, and the refracted light will be transmitted to the Raman spectrum detector for processing and detection, so that the Raman spectrum detector can detect the LED lamp more comprehensively and with better results.

[0012] Preferably, a group of sliding rods are fixedly installed on the outer sides of the two rectangular plates, and a round block is fixedly installed on one end of the two groups of sliding rods. The outer walls of the two groups of sliding rods are respectively slidably connected to the inner walls of the two frame plates, and return springs are arranged between the two groups of round blocks and the two frame plates. The two groups of return springs are respectively placed on the outsides of the two groups of sliding rods. When the rectangular plates move, the round block on one end of the sliding rod squeezes the return spring to move, and the sliding rod will slide on the inner wall of the frame plate. After the Raman spectrum detector has finished detecting the LED lamp, the motor drives the focusing tube and the extrusion block to move back to their positions, the force-bearing block will lose its thrust, and the return spring will drive the rectangular plate to reset through the elastic force, and the two refracting mirror plates will move out from the bottom of the LED lamp, which is convenient for moving the LED lamp out. This process can also facilitate the detection of LED lamps one by one during production.

[0013] Preferably, a correction axis is symmetrically fixedly installed on the outer wall of one of the refracting mirror plates, and the two correction axes are slidably connected to the inner wall of the other refracting mirror plate. When the two refracting mirror plates are in contact, the correction axis on one of the refracting mirror plates will be inserted into the other refracting mirror plate. When the correction axis is fully inserted, the two refracting mirror plates form a complete refractive arc surface. The setting of the correction axis plays a correction role to prevent the two refracting mirror plates from being misaligned during sliding contact and unable to fully contact each other.

[0014] Preferably, a release box is provided on the top of the conveyor, and inclined sliding blocks are fixedly installed on both sides of the release box, and the inner wall of the release box is symmetrically slidably connected with a release block, and the outer walls of the two release blocks are fixedly installed with a limited sliding shaft, one end of the limited sliding shaft is fixedly connected to the inner wall of the release box, and a push block spring is provided between the inner wall of the release box and the outer wall of the release block, and the push block spring is placed outside the limited sliding shaft. When the conveyor drives the LED lamp to move, when the LED lamp moves into the release box, it stops moving. When the LED lamp moves into the release box, the bottom of the LED lamp will push the release block in the release box to squeeze the push block spring to slide on the limited sliding shaft. When sliding to a certain extent, the two release blocks stop sliding. At this time, the LED lamp is completely in the release box, and the power connection end of the LED lamp will be placed between the two release blocks. Then an external power supply is connected to energize the release block, and the LED lamp will generate a light source, which plays a role in lighting up the LED lamp.

[0015] Preferably, a lamp holder is provided on the top of the conveyor. During inspection, the LED lamp is placed in the lamp holder, and then the conveyor drives the lamp holder to move into the release box so that the Raman spectrum detector can detect it. Usually, this design and arrangement allows the LED lamps to be inspected one by one during production, saving the process of inspecting them one by one after the LED lamps are produced, which is more conducive to production and processing.

[0016] Preferably, the casual wear component includes a lap frame, which is fixedly installed inside the installation box. The inner bottom of the installation box is slidably connected with a lifting block, and the bottom of the lifting block is fixedly installed with a hydraulic press. During installation, the lap frame is placed on the top of both sides of the conveyor, and then the lifting block is placed on the bottom of the conveyor, and the hydraulic press is placed on the ground. Through the continuous raising of the hydraulic press, the lifting block will slide on the installation box. When the top of the lifting block completely contacts the bottom of the conveyor, the hydraulic press stops operating. At this time, the conveyor will be completely stuck between the lifting block and the lap frame, completely connecting the conveyor and the detection box. The lifting block is supported by the hydraulic expansion and contraction of the hydraulic press, which is convenient for assembly and disassembly.

[0017] Preferably, vertical legs are fixedly installed at the bottom of the two frames. During installation, the vertical legs at the bottom of the frames are placed on both sides of the conveyor, and then the vertical legs are connected to the conveyor by bolts and nuts. The lifting block is then moved by the hydraulic expansion and contraction of the hydraulic machine to connect the inspection box and the conveyor. The setting of the vertical legs can strengthen the fixation between the inspection box and the conveyor to prevent the inspection box from collapsing during operation.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The Raman spectrum detection device for LED production described in the present invention drives the focusing tube to move downward by a motor, and at the same time drives the pressure plate to move, thereby driving the rectangular plate to slide out of the groove plate, and the refracting mirror plate on one end of the rectangular plate will slowly extend out. When the two refracting mirror plates, one on the left and one on the right, are in contact, the focusing tube covers the LED lamp, the focusing tube is placed above the two refracting mirror plates, and the LED lamp is placed between the two. The two refracting mirror plates form a refractive arc surface below the LED lamp. When the LED lamp is on, the refracting mirror plate refracts the light emitted from the bottom of the LED lamp, so that the detection is more comprehensive and the effect is better.

[0020] 2.

[0021] 3. The Raman spectrum detection device for LED production described in the present invention, after the LED lamp is detected by the Raman spectrum detector, the motor drives the focusing tube and the extrusion block to move back to their positions, the force-bearing block will lose the thrust, the reset spring will drive the moment plate to reset through the elastic force, and the two refracting mirror plates will move out from the bottom of the LED lamp. Usually, this design and arrangement allows the LED lamps to be detected one by one during production, saving the process of detecting them one by one after the LED lamps are produced, which is more conducive to production and processing.

[0022] 4.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 9 As shown, a Raman spectrum detection device for LED production according to an embodiment of the present invention comprises a conveyor 2, a mounting box 3 is symmetrically arranged on the top of the conveyor 2, a detection box 1 is fixedly installed on the top of the two mounting boxes 3, a light collecting component is arranged inside the detection box 1, the light collecting component is used to refract and concentrate the light emitted from the bottom of the LED lamp, and plays the role of a concentrated light source, a casual component is arranged inside the mounting box 3, the casual component is used to connect and install the detection box 1 with the conveyor 2, and plays the role of facilitating assembly, and a Raman spectrum detector 30 is arranged inside the detection box 1;

[0036] In the current prior art, when detecting LED lamps, since the light source of the LED lamps is scattered in all directions when being scattered, the detection device does not fully capture the light source when detecting the LED lamps, and the detected data is not detailed, which affects the detection effect;

[0037] During installation, the detection box 1 is placed above the conveyor 2, and then the installation box 3 is placed on both sides of the conveyor 2. The detection box 1 and the conveyor 2 are installed and connected through the casual components in the installation box 3. The setting of the casual components facilitates assembly and disassembly. Then, the LED lamp to be detected is placed on the conveyor 2, and the conveyor 2 drives the LED lamp to move to the bottom of the detection box 1. Then, the Raman spectrum detector 30 in the detection box 1 captures the light emitted by the LED lamp. At the same time, the light collecting component refracts and concentrates the light emitted from the bottom of the LED lamp, assisting the Raman spectrum detector 30 to capture the scattered light that cannot be captured. Then, the Raman spectrum detector 30 uses the Raman signal excited by the LED light source to detect the light. A bandpass filter and a photodetector with special spectral transmittance obtain Raman narrowband measurement signals, and then a Raman spectrum with high spectral resolution is reconstructed through a data post-processing module. The data is finally displayed on a monitor for easy observation by people, which plays a role in detection. The light emitted from the bottom of the LED lamp is refracted and concentrated through a light collecting component, which can solve the above-mentioned problem that the light source of the LED lamp is scattered all around when it is emitted, resulting in the detection device not fully capturing the light source when detecting the LED lamp, and the detected data is not detailed, which affects the detection effect. It should be noted here that the outer shape of the LED lamp is a bulb. The attached figure of this scheme shows the working state of the device, and the conveyor 2 is an intermittent conveying device.

[0038] like Figures 1 to 7 As shown, a plate 7 and a limiting plate 32 are fixedly installed on the top of the inner wall of the detection box 1, a motor 4 is fixedly installed on the top of the plate 7, a plurality of fixed ring rods 20 are fixedly installed on the bottom of the plate 7, a fixing ring 19 is fixedly installed on one end of the plurality of fixed ring rods 20, the fixing ring 19 is arranged in the middle of the inner wall of the limiting plate 32, and the Raman spectrum detector 30 is fixedly installed in the fixing ring 19;

[0039] During installation, the Raman spectrum detector 30 is set in the retaining ring 19, and the Raman spectrum detector 30 is hung on the bottom of the mounting plate 7 through the retaining ring rod 20. The retaining ring 19 is placed in the middle of the inner wall of the limiting plate 32, so that the Raman spectrum detector 30 can maintain a stable receiving distance with the LED lamp during detection work, and when the motor 4 drives the subsequent process operation, it will not interfere with it and cause any impact. It should be noted here that the distance between the Raman spectrum detector 30 and the LED lamp needs to be actually measured.

[0040] like Figures 4 to 5As shown, the output end of the motor 4 is fixedly mounted with a shaft disc 18, the shaft disc 18 is slidably connected to the outer wall of a plurality of fixed ring rods 20, a plurality of connecting rods 21 are fixedly mounted on the bottom of the shaft disc 18, a focusing tube 5 is fixedly mounted on the bottom end of the plurality of connecting rods 21, the focusing tube 5 is slidably connected to the outer wall of the retaining ring 19, the retaining ring 19 is placed in the middle of the light focusing tube 5, the light focusing tube 5 is slidably connected to the inner wall of the limiting plate 32, and the inside of the detection box 1 is symmetrically fixedly mounted with frame plates 6, and the outer walls of the two frame plates 6 are fixedly connected to the inner walls of the placement plate 7 and the limiting plate 32;

[0041] When the conveyor 2 drives the LED lamp to be placed under the detection box 1, the motor 4 drives the shaft disk 18 to move downward. When the shaft disk 18 moves downward, the shaft disk 18 drives the focusing tube 5 to move downward through multiple connecting rods 21. When the motor 4 drives the focusing tube 5 to cover the LED lamp, the motor 4 stops working. At this time, the light collecting component refracts and concentrates the light diverged from the bottom of the LED lamp, which is convenient for the Raman spectrum detector 30 to better detect the LED lamp. The LED lamp is covered by the focusing tube 5, so that when the Raman spectrum detector 30 is detecting, the focusing tube 5 can better prevent the divergence of the LED lamp, which plays a role in limiting the divergence of the light source. The setting of the frame 6 can play a supporting role. It should be noted here that the size of the focusing tube 5 needs to be actually measured and calculated.

[0042] like Figures 4 to 6 As shown, the light collecting assembly includes a folding mirror plate 16, and the number of the folding mirror plates 16 is two. The outer walls of the two folding mirror plates 16 are fixedly installed with a rectangular plate 15, and the top of the rectangular plate 15 is fixedly installed with a force block 17. The outer walls of the two frame plates 6 are fixedly installed with a slot plate 10, and the bottoms of the two rectangular plates 15 are respectively slidably connected with the inner walls of the two slot plates 10. The outer wall of the shaft disc 18 is symmetrically fixedly installed with a pressing plate 9, and the bottoms of the two pressing plates 9 are fixedly installed with an extrusion block 8, and the outer walls of the two extrusion blocks 8 are respectively slidably connected with the outer walls of the two force blocks 17;

[0043] When the motor 4 drives the focusing tube 5 to move downward toward the LED lamp cover through the shaft disc 18, the shaft disc 18 also drives the pressure plate 9 to move. When the pressure plate 9 moves, it drives the squeezing block 8 to move downward. When the squeezing block 8 moves downward, it squeezes the force-bearing block 17 to move. When the force-bearing block 17 moves, it will drive the rectangular plate 15 to slide out of the groove plate 10, and the refracting mirror plate 16 on one end of the rectangular plate 15 will slowly extend out. When the left and right refracting mirror plates 16 are driven to complete contact, the focusing tube 5 will cover the LED lamp, and the focusing tube 5 will be placed above the two refracting mirror plates 16, and the LED lamp will be placed between the two refracting mirror plates 16. In the middle, the two refracting mirror plates 16 will form a refractive arc surface under the LED lamp. When the LED lamp is on, the refracting mirror plate 16 refracts the light emitted from the bottom of the LED lamp, and the refracted light will be transmitted to the Raman spectrum detector 30 for processing and detection, so that the Raman spectrum detector 30 can detect the LED lamp more comprehensively and effectively. It should be noted here that the size of the refracting mirror plate 16 needs to be actually measured, and the downward movement distance of the focusing tube 5 and the movement distance of the two refracting mirror plates 16 need time to be measured and obtained.

[0044] like Figures 4 to 5 As shown, a set of slide bars 14 are fixedly installed on the outer sides of the two rectangular plates 15, and a round block 12 is fixedly installed on one end of the two sets of slide bars 14. The outer walls of the two sets of slide bars 14 are respectively slidably connected to the inner walls of the two frame plates 6. A return spring 13 is arranged between the two sets of round blocks 12 and the two frame plates 6. The two sets of return springs 13 are respectively placed on the outside of the two sets of slide bars 14;

[0045] When the moment plate 15 moves, the round block 12 on one end of the slide bar 14 squeezes the reset spring 13 to move, and the slide bar 14 will slide on the inner wall of the frame plate 6. When the Raman spectrum detector 30 has finished detecting the LED lamp, the motor 4 drives the focusing tube 5 and the squeezing block 8 to move back to their positions, and the force-bearing block 17 will lose its thrust. The reset spring 13 will drive the moment plate 15 to reset through elastic force, and the two refracting mirror plates 16 will move out from the bottom of the LED lamp, making it easy to move the LED lamp out. This process can also facilitate the detection of LED lamps one by one during production.

[0046] like Figure 5 to Figure 6 As shown, the outer wall of one of the folding mirror plates 16 is symmetrically fixed with a correction shaft 31, and the two correction shafts 31 are slidably connected to the inner wall of the other folding mirror plate 16;

[0047] When the two refracting mirror plates 16 are in contact, the correction axis 31 on one of the refracting mirror plates 16 will be inserted into the other refracting mirror plate 16. When the correction axis 31 is fully inserted, the two refracting mirror plates 16 form a complete refractive arc surface. The setting of the correction axis 31 plays a correction role to prevent the two refracting mirror plates 16 from being misaligned during sliding contact and unable to fully contact each other. It should be noted here that the length of the correction axis 31 needs to be actually measured.

[0048] like Figures 1 to 9 As shown, a release box 25 is provided on the top of the conveyor 2, and inclined sliders 11 are fixedly installed on both sides of the release box 25. The inner wall of the release box 25 is symmetrically slidably connected with a release block 26. The outer walls of the two release blocks 26 are fixedly installed with a limited sliding shaft 27, and one end of the limited sliding shaft 27 is fixedly connected to the inner wall of the release box 25. A push block spring 28 is provided between the inner wall of the release box 25 and the outer wall of the release block 26, and the push block spring 28 is placed outside the limited sliding shaft 27.

[0049] When the conveyor 2 drives the LED lamp to move, when the LED lamp moves into the release box 25, it stops moving. When the LED lamp moves into the release box 25, the bottom of the LED lamp will push the release block 26 in the release box 25 to squeeze the push block spring 28 to slide on the limited sliding shaft 27. When sliding to a certain extent, the two release blocks 26 stop sliding. At this time, the LED lamp is completely in the release box 25, and the power connection end of the LED lamp will be placed between the two release blocks 26. Then, an external power supply is connected to energize the release block 26, and the LED lamp will generate a light source to light up the LED lamp. It should be noted here that except for the release block 26 which is made of energized material, the other components are made of insulating materials.

[0050] like Figures 1 to 9 As shown, a lamp holder 29 is provided on the top of the conveyor 2;

[0051] During detection, the LED lamp is placed in the lamp holder 29, and then the conveyor 2 drives the lamp holder 29 to move into the discharge box 25, so that the Raman spectrum detector 30 can detect it. Usually, this design and arrangement allows the LED lamps to be detected one by one during production, saving the process of testing them one by one after the LED lamps are produced, which is more conducive to production and processing.

[0052] like Figures 7 and 8 As shown, the casual wear assembly includes a lap frame 24, which is fixedly installed inside the installation box 3. The bottom of the interior of the installation box 3 is slidably connected with a lifting block 22, and the bottom of the lifting block 22 is fixedly installed with a hydraulic press 33;

[0053] During installation, the lap frame 24 is placed on the top of both sides of the conveyor 2, and then the lifting block 22 is placed at the bottom of the conveyor 2, and the hydraulic press 33 is placed on the ground. As the hydraulic press 33 is continuously raised, the lifting block 22 will slide on the installation box 3. When the top of the lifting block 22 completely contacts the bottom of the conveyor 2, the hydraulic press 33 stops working. At this time, the conveyor 2 will be completely stuck between the lifting block 22 and the lap frame 24, completely connecting the conveyor 2 and the detection box 1. The lifting block 22 is supported by the hydraulic expansion and contraction of the hydraulic press 33, which is convenient for assembly and disassembly.

[0054] like Figures 7 and 8 As shown, the bottom of the two frame plates 6 are fixedly mounted with vertical legs 23;

[0055] During installation, the vertical legs 23 at the bottom of the frame plate 6 are placed on both sides of the conveyor 2, and then the vertical legs 23 are connected to the conveyor 2 by bolts and nuts. Then, the lifting block 22 is moved by the hydraulic expansion and contraction of the hydraulic cylinder 33 to connect the detection box 1 and the conveyor 2. The setting of the vertical legs 23 can strengthen the fixation between the detection box 1 and the conveyor 2 to prevent the detection box 1 from collapsing during operation.

[0056] Working principle: During installation, the detection box 1 is placed above the conveyor 2, and then the installation box 3 is placed on both sides of the conveyor 2. The detection box 1 and the conveyor 2 are installed and connected through the casual components in the installation box 3. The setting of the casual components facilitates assembly and disassembly. Then, the LED lamp to be detected is placed on the conveyor 2, and the conveyor 2 drives the LED lamp to move to the bottom of the detection box 1. Then, the Raman spectrum detector 30 in the detection box 1 captures the light emitted by the LED lamp. At the same time, the light collecting component refracts and concentrates the light emitted from the bottom of the LED lamp, and assists the Raman spectrum detector 30 to capture the scattered light that cannot be captured. Then, the Raman spectrum detector 30 uses the Raman signal excited by the LED light source to obtain the Raman narrowband measurement signal through the bandpass filter and photodetector with special spectral transmittance, and then reconstructs the Raman spectrum with high spectral resolution through the data post-processing module. Finally, the data is displayed on the display for people to observe and play a detection role.

[0057] During installation, the Raman spectrum detector 30 is placed in the retaining ring 19, and the Raman spectrum detector 30 is hung on the bottom of the mounting plate 7 through the retaining ring rod 20. The retaining ring 19 is placed in the middle of the inner wall of the limiting plate 32, so that the Raman spectrum detector 30 can maintain a stable receiving distance with the LED lamp during detection work, and when the motor 4 drives the subsequent process operation, it will not interfere with it and cause any impact;

[0058] When the conveyor 2 drives the LED lamp to be placed under the detection box 1, the motor 4 drives the shaft disc 18 to move downward. When the shaft disc 18 moves downward, the shaft disc 18 drives the focusing tube 5 to move downward through multiple connecting rods 21. When the motor 4 drives the focusing tube 5 to cover the LED lamp, the motor 4 stops working. At this time, the light collecting component refracts and concentrates the light diverged from the bottom of the LED lamp, so that the Raman spectrum detector 30 can better detect the LED lamp. The LED lamp is covered by the focusing tube 5, so that when the Raman spectrum detector 30 is detecting, the focusing tube 5 can better prevent the divergence of the LED lamp, thereby limiting the divergence of the light source.

[0059] When the motor 4 drives the focusing tube 5 to move downward toward the LED lamp cover through the shaft disc 18, the shaft disc 18 also drives the pressure plate 9 to move. When the pressure plate 9 moves, it drives the squeezing block 8 to move downward. When the squeezing block 8 moves downward, it squeezes the force-bearing block 17 to move. When the force-bearing block 17 moves, it will drive the rectangular plate 15 to slide out of the groove plate 10, and the refracting mirror plate 16 on one end of the rectangular plate 15 will slowly extend out. When the two refracting mirror plates 16 on the left and right complete contact through driving, the focusing tube 5 will cover the LED lamp at this time, and the focusing tube 5 will be placed above the two refracting mirror plates 16, and the LED lamp will be placed between the two. The two refracting mirror plates 16 will form a refractive arc surface below the LED lamp. When the LED lamp is on, the refracting mirror plate 16 refracts the light emitted from the bottom of the LED lamp, and the refracted light will be transmitted to the Raman spectrum detector 30 for processing and detection, so that the Raman spectrum detector 30 can detect the LED lamp more comprehensively and with better effect.

[0060] When the moment plate 15 moves, the round block 12 on one end of the slide bar 14 squeezes the reset spring 13 to move, and the slide bar 14 will slide on the inner wall of the frame plate 6. When the Raman spectrum detector 30 has finished detecting the LED lamp, the motor 4 drives the focusing tube 5 and the squeeze block 8 to move back to their positions, and the force-bearing block 17 will lose its thrust. The reset spring 13 will drive the moment plate 15 to reset through elastic force, and the two refracting mirror plates 16 will move out from the bottom of the LED lamp, making it easy to move the LED lamp out. This process can also facilitate the detection of LED lamps one by one during production.

[0061] When the two folding mirror plates 16 are in contact, the correction axis 31 on one of the folding mirror plates 16 will be inserted into the other folding mirror plate 16. When the correction axis 31 is fully inserted, the two folding mirror plates 16 form a complete refractive arc surface. The setting of the correction axis 31 plays a correction role, preventing the two folding mirror plates 16 from being offset when sliding in contact and failing to be fully in contact with each other.

[0062] When the conveyor 2 drives the LED lamp to move, when the LED lamp moves into the power-release box 25, it stops moving. When the LED lamp moves into the power-release box 25, the bottom of the LED lamp pushes the power-release block 26 in the power-release box 25 to squeeze the push block spring 28 to slide on the limited sliding shaft 27. When sliding to a certain extent, the two power-release blocks 26 stop sliding. At this time, the LED lamp is completely in the power-release box 25, and the power-connecting end of the LED lamp is placed between the two power-release blocks 26. Then, an external power supply is connected to energize the power-release block 26, and the LED lamp generates a light source, which plays the role of lighting the LED lamp.

[0063] During the inspection, the LED lamp is placed in the lamp holder 29, and then the conveyor 2 drives the lamp holder 29 to move into the discharge box 25, so that the Raman spectrum detector 30 can inspect it. Usually, such a design and placement allows the LED lamps to be inspected one by one during production, saving the process of inspecting the LED lamps one by one after they are produced, which is more conducive to production and processing;

[0064] During installation, the lapped frames 24 are placed on the top of both sides of the conveyor 2, and then the lifting block 22 is placed at the bottom of the conveyor 2, and the hydraulic press 33 is placed on the ground. As the hydraulic press 33 is continuously raised, the lifting block 22 will slide on the installation box 3. When the top of the lifting block 22 completely contacts the bottom of the conveyor 2, the hydraulic press 33 stops working. At this time, the conveyor 2 will be completely stuck between the lifting block 22 and the lapped frames 24, and the connection between the conveyor 2 and the detection box 1 is completely supported. The lifting block 22 is driven by the hydraulic expansion and contraction of the hydraulic press 33, which is convenient for assembly and disassembly.

[0065] During installation, the vertical legs 23 at the bottom of the frame plate 6 are placed on both sides of the conveyor 2, and then the vertical legs 23 are connected to the conveyor 2 by bolts and nuts. Then, the lifting block 22 is moved by the hydraulic expansion and contraction of the hydraulic cylinder 33 to connect the detection box 1 and the conveyor 2. The setting of the vertical legs 23 can strengthen the fixation between the detection box 1 and the conveyor 2 to prevent the detection box 1 from collapsing during operation.
