DETAILED DESCRIPTION

[0030] 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.

[0031] like Figures 1 to 3 As shown, a continuous detection system for LED chips based on Raman spectroscopy according to an embodiment of the present invention comprises a conveyor frame 1, a supporting leg 2 is installed at the bottom end of the conveyor frame 1, the supporting leg 2 comprises a supporting rod 20 and a first hydraulic cylinder 21, the top end of the output end of the first hydraulic cylinder 21 is connected to the bottom end of the supporting rod 20, and the top end of the supporting rod 20 is connected to the bottom end of the conveyor frame 1; a conveyor belt 4 is installed on the surface of the conveyor frame 1; a plurality of carrying plates 41 are evenly arranged on the surface of the conveyor belt 4, and a connecting piece is arranged between the carrying plates 41 and the conveyor belt 4; a Raman spectrometer 3 is arranged on one side of the conveyor frame 1, and the output end of the Raman spectrometer 3 is located directly above the conveyor belt 4;

[0032] In actual detection, especially when detecting objects in batches, it is necessary to manually place the detected objects on the detection pool and take them out after the detection is completed. The whole detection process is inefficient and is not conducive to the detection of large quantities of objects. To solve the above problems, the embodiment of the present invention is provided with a conveyor belt 4. When in use, the conveyor frame 1 is placed below the output end of the Raman spectrometer 3, and then the LED chip to be detected is placed on the surface of the carrier plate 41, and the conveyor belt 4 is controlled to rotate. The conveyor belt 4 drives the chip on the carrier plate 41 to stop when it reaches the output end of the Raman spectrometer 3. After that, when the Raman spectrometer 3 completes the chip detection, the conveyor belt 4 is controlled to continue to rotate, and the conveyor belt 4 drives the chip on the carrier plate 41 to move. The detected chip is separated from the detection station of the Raman spectrometer 3, and the undetected chip enters the detection station for continued detection. The whole detection process is smooth, and the staff only needs to take and place the chip on the carrier plate 41; the detection efficiency of the LED chip is improved; it is conducive to the detection of large quantities of chips; it should be pointed out that the height of the conveyor frame 1 can be adjusted by the first hydraulic cylinder 21 in conjunction with the support rod 20, and then the height of the detected chip is adjusted to meet the detection position requirements.

[0033] The connecting piece is specifically a rubber strip 42, one side of the rubber strip 42 is connected to the center of the supporting plate 41, and the other side is connected to the surface of the conveyor belt 4; when the conveyor belt 4 drives the supporting plate 41 to rotate to the corner, the rubber strip 42 can be deformed accordingly to prevent the supporting plate 41 from pulling the conveyor belt 4 at the corner, causing damage to the conveyor belt 4.

[0034] A pair of support springs 43 are symmetrically arranged on the side of the supporting plate 41 facing the conveyor belt 4 based on the rubber strip 42, and a pad 44 is arranged on the end of the supporting spring 43 away from the supporting plate 41, and the pad 44 is pressed against the surface of the conveyor belt 4; when in use, the supporting plate 41 supports the areas on both sides of the rubber strip 42 through the cooperation of the support springs 43 and the pad 44, so that the supporting plate 41 remains stable during use.

[0035] like Figures 4 to 5 As shown, a receiving frame 5 is arranged above the conveyor belt 4, a pair of supporting rollers 51 are arranged symmetrically on the side of the receiving frame 5 based on the center, a rotating belt 52 is sleeved on the surface of the pair of supporting rollers 51, a first connecting frame 53 is arranged on the side of the receiving frame 5, a second hydraulic cylinder 54 is arranged below the first connecting frame 53, the top end of the output end of the second hydraulic cylinder 54 is connected to the first connecting frame 53, and a fixing member 55 is sleeved on the shell part of the second hydraulic cylinder 54;

[0036] A second connecting frame 56 is provided at the bottom end of the fixing member 55, one end of the second connecting frame 56 is fixedly connected to the bottom surface of the conveying frame 1, and the other end is provided with a fourth hydraulic cylinder 57, and the output end of the fourth hydraulic cylinder 57 is connected to the side of the fixing member 55; when the conveyor belt 4 drives the carrying plate 41 to move, the second hydraulic cylinder 54 can be driven to move through the fourth hydraulic cylinder 57 and the fixing member 55, and then the second hydraulic cylinder 54 drives the receiving frame 5 to move through the first connecting frame 53, and the receiving frame 5 drives the rotating belt 52 to move to the top of the conveyor belt 4 through the supporting roller 51, and then the second hydraulic cylinder 54 drives the receiving frame 5 to move through the first connecting frame 53, and the receiving frame 5 drives the rotating belt 52 to move to the top of the conveyor belt 4 through the supporting roller 51, and then the second hydraulic cylinder 54 drives the rotating belt 52 to move downward and stops when the rotating belt 52 contacts the chip on the top surface of the carrier plate 41. Then, as the conveyor belt 4 rotates, the conveyor belt 4 drives the chip on the carrier plate 41 to move. When the chip moves, the friction force drives the rotating belt 52 to rotate. Therefore, the chip is continuously covered by the rotating belt 52 when it moves. The conveyor belt 4 can adaptably increase the rotation speed and improve the chip transportation efficiency without causing the chip to fall off the carrier plate 41. When detecting the chip, the fourth hydraulic cylinder 57 moves the rotating belt 52 away from the top of the conveyor belt 4 to avoid affecting the chip detection.

[0037] The surface of the rotating belt 52 is covered with a layer of sponge; when the rotating belt 52 is pressed onto the chip on the carrier plate 41 , the sponge on the rotating belt 52 will protect the chip to prevent the chip from being damaged when being pressed.

[0038] An output motor 6 is installed on the side of the receiving frame 5, and the output end of the output motor 6 is connected to one end of a pair of support rollers 51; when the rotating belt 52 is pressed onto the chip, as the conveyor belt 4 rotates, the output motor 6 controls the support rollers 51 to drive the rotating belt 52 to rotate synchronously, so that when the rotating belt 52 is pressed onto the chip, no interlacing force is generated between the chip and the rotating belt 52, thereby further ensuring the stability of chip transportation.

[0039] A pair of reinforcing rods 7 are symmetrically arranged on the side of the receiving frame 5 based on the center, and a receiving block 71 is sleeved on the surface of the reinforcing rod 7. A fixed cylinder 72 is arranged below the receiving block 71. The side of the fixed cylinder 72 is installed on the side of the conveying frame 1, and the bottom end of the receiving block 71 is inserted into the inside of the fixed cylinder 72; when the receiving frame 5 moves horizontally, the reinforcing rod 7 is driven to move horizontally relative to the receiving block 71. When the receiving frame 5 moves vertically, the reinforcing rod 7 drives the receiving block 71 to move up and down in the fixed cylinder 72, so that the reinforcing rod 7 continuously supports the receiving frame 5, thereby ensuring the stability of the receiving frame 5 during use.

[0040] like Figures 1 to 7As shown, the unloading end of the conveyor belt 4 is provided with a receiving plate 8, and the bottom end of the receiving plate 8 is provided with a support member 81; the top of the receiving plate 8 includes a vertical surface and an inclined surface; when the conveyor belt 4 rotates, the side of the carrier plate 41 used for carrying the chip can be connected with the inclined surface of the receiving plate 8, that is, with the rotation of the conveyor belt 4, the end of the inclined surface of the receiving plate 8 slides on the side of the carrier plate 41 used for carrying the chip, and then the carried chip is connected to the inclined surface of the receiving plate 8; after the chip detection on the carrier plate 41 is completed, with the continuous rotation of the conveyor belt 4, when the detected chip is conveyed to the unloading end, the surface of the lower carrier plate 41 is connected with the inclined surface of the receiving plate 8, and with the flipping of the carrier plate 41, the chip on the surface will gradually transfer to the inclined surface of the receiving plate 8, and then the staff can remove the chip on the receiving plate 8. Compared with directly unloading on the carrier plate 41, corresponding buffering can be performed, that is, the receiving plate 8 can receive multiple chips at once, which is beneficial to reduce the labor intensity of the staff.

[0041] A plurality of through holes are provided on the top surface of the inclined surface of the receiving plate 8; a rubber column 93 is inserted into the inside of the through hole, a connecting plate 92 is provided at the bottom end of the rubber column 93, a fifth hydraulic cylinder 91 is provided below the connecting plate 92, and the output end of the fifth hydraulic cylinder 91 is connected to the bottom surface of the connecting plate 92; a fixing frame 9 is provided at the bottom end of the receiving plate 8, and the shell part of the fifth hydraulic cylinder 91 is installed on the fixing frame 9; after the receiving plate 8 receives the chip, the fifth hydraulic cylinder 91 is started, and the fifth hydraulic cylinder 91 drives the rubber column 93 to move upward through the connecting plate 92, and the top end of the rubber column 93 moves to the top of the inclined surface through the through hole, contacts with the bottom surface of the chip on the inclined surface and generates an extrusion force, so that there is friction between the chip and the rubber column 93, preventing the chip from sliding down from the inclined surface of the receiving plate 8.

[0042] The top surface of the lead plate 8 is polished to prevent the chip from being damaged by friction when it moves on the lead plate 8 .

[0043] During operation, the conveyor rack 1 is placed below the output end of the Raman spectrometer 3, and then the LED chip to be detected is placed on the surface of the carrier plate 41, and the conveyor belt 4 is controlled to rotate. The conveyor belt 4 drives the chip on the carrier plate 41 to stop when it reaches the bottom of the output end of the Raman spectrometer 3. After that, when the Raman spectrometer 3 completes the chip detection, the conveyor belt 4 is controlled to continue to rotate, and the conveyor belt 4 drives the chip on the carrier plate 41 to move. The detected chip leaves the detection station of the Raman spectrometer 3, and the undetected chip enters the detection station for further detection. The whole detection process is smooth, and the staff only needs to take and place the chip on the carrier plate 41. It can improve the detection efficiency of LED chips and is conducive to the detection of large quantities of chips. It should be pointed out that the height of the conveyor frame 1 can be adjusted by the first hydraulic cylinder 21 in cooperation with the support rod 20, and then the height of the detected chip can be adjusted to meet the detection position requirements. When the conveyor belt 4 drives the supporting plate 41 to rotate to the corner, the rubber strip 42 can be deformed accordingly to prevent the supporting plate 41 from pulling the conveyor belt 4 at the corner, causing damage to the conveyor belt 4. When in use, the supporting plate 41 cooperates with the support spring 43 and the pad 44 to support the area on both sides of the rubber strip 42, so that the supporting plate 41 remains stable during use.

[0044] When the conveyor belt 4 drives the carrier plate 41 to move, the fourth hydraulic cylinder 57 and the fixing member 55 can drive the second hydraulic cylinder 54 to move, and then the second hydraulic cylinder 54 drives the receiving frame 5 to move through the first connecting frame 53, and the receiving frame 5 drives the rotating belt 52 to move above the conveyor belt 4 through the supporting roller 51, and then the rotating belt 52 is driven downward by the second hydraulic cylinder 54, and stops when the rotating belt 52 contacts the chip on the top surface of the carrier plate 41, and then with the rotation of the conveyor belt 4, the conveyor belt 4 drives the chip on the carrier plate 41 to move, and the friction force drives the rotating belt 52 to rotate when the chip moves, so the chip is continuously covered by the rotating belt 52 when it moves, and the conveyor belt 4 can adaptably increase the rotation speed and improve the chip transportation efficiency without causing the chip to fall off the carrier plate 41; when detecting the chip, the rotating belt 52 is moved by the fourth hydraulic cylinder 57 The rotating belt 52 is automatically separated from the top of the conveyor belt 4 to avoid affecting the detection of the chip; the surface of the rotating belt 52 is covered with a layer of sponge; when the rotating belt 52 is pressed onto the chip on the supporting plate 41, the sponge on the rotating belt 52 will protect the chip to avoid damage to the chip when being pressed; when the rotating belt 52 is pressed onto the chip, as the conveyor belt 4 rotates, the output motor 6 controls the supporting roller 51 to drive the rotating belt 52 to rotate synchronously, so that when the rotating belt 52 is pressed onto the chip, no interlacing force is generated between the chip and the rotating belt 52, further ensuring the stability of chip transportation; when the receiving frame 5 moves horizontally, the reinforcing rod 7 is driven to move horizontally relative to the receiving block 71, and when the receiving frame 5 moves vertically, the reinforcing rod 7 drives the receiving block 71 to move up and down in the fixed tube 72, so that the reinforcing rod 7 continues to support the receiving frame 5 to ensure the stability of the receiving frame 5 during use.

[0045] When the conveyor belt 4 rotates, one side of the carrier plate 41 used for carrying the chip can be butted against the inclined surface of the receiving plate 8, that is, as the conveyor belt 4 rotates, the end of the inclined surface of the receiving plate 8 slides on the side of the carrier plate 41 used for carrying the chip, and then the carried chip is received on the inclined surface of the receiving plate 8; after the chip detection on the carrier plate 41 is completed, as the conveyor belt 4 continues to rotate, when the detected chip is conveyed to the unloading end, the surface of the lower carrier plate 41 is butted against the inclined surface of the receiving plate 8, and as the carrier plate 41 flips, the chip on the surface will gradually transfer to the inclined surface of the receiving plate 8, and then the staff can remove the chip on the receiving plate 8. Compared with unloading directly on the carrier plate 41, corresponding buffering can be performed, that is, the receiving plate 8 can receive multiple chips at the same time, which is beneficial to reducing the labor intensity of the staff; after the receiving plate 8 receives the chip, the fifth hydraulic cylinder 91 is started, and the fifth hydraulic cylinder 91 drives the rubber column 93 to move upward through the connecting plate 92, and the top of the rubber column 93 moves to the top of the inclined surface through the through hole, contacts the bottom surface of the chip on the inclined surface and generates an extrusion force, so that there is friction between the chip and the rubber column 93, preventing the chip from sliding down from the inclined surface of the receiving plate 8; wherein the top surface of the receiving plate 8 is polished to prevent the chip from being damaged by friction when moving on the receiving plate 8.
