Technical Field

[0001] This application relates to the technical field of testing equipment for spectrometers, and in particular to a rapid testing device for a patch spectrometer. Background Technology

[0002] SMD LED spectrometers are widely used in the LED lighting industry to classify LED chips of different colors and brightness levels, ensuring product quality consistency and reliability. With the rapid development of LED technology, the application scope of SMD LED spectrometers is constantly expanding, not only improving production efficiency but also significantly enhancing product market competitiveness. However, in actual production, the use of SMD LED spectrometers often involves a significant amount of preliminary work, especially in the quality inspection of the LED chips, a crucial step in ensuring the performance of the final product.

[0003] Currently, the methods and technologies used in the industry to inspect LED chips have solved the problem to some extent, but some obvious shortcomings still exist. Firstly, the inspection speed is slow, especially in large-scale production, where traditional inspection methods cannot meet the requirements for high efficiency. Summary of the Invention

[0004] To overcome the aforementioned technical problems, this application provides a rapid detection device for a patch spectrometer.

[0005] This application provides a rapid detection device for a patch spectrometer, which adopts the following technical solution: A rapid detection device for a surface mount spectrometer includes a feeding hopper, a vibrating plate, a detection mechanism, and a storage mechanism. The detection mechanism includes a detection disc and a detection assembly. The detection assembly includes two opposing detection electrode blocks, each with an electrode contact. A gap exists between the two electrode contacts, and the two electrode contacts are connected to the detection electrode blocks via torsion springs. A drive shaft is vertically positioned in the center of the detection disc, and a disc drive motor is connected to the bottom of the drive shaft. Multiple detection protrusions are arranged in a ring around the outer side of the detection disc. A detection groove is formed at the top of each detection protrusion, and an electrode contact is provided at the bottom of the groove. Each detection protrusion is adjacent to a voltage contact block, which is fixedly mounted on the upper surface of the detection disc. A voltmeter contact block is located at the top of each voltage contact block.

[0006] By adopting the above technical solution, electrode contacts are set on the detection electrode block, and the electrode contacts are connected to the detection electrode block by a torsion spring. When the detection protrusion passes through the electrode contacts, it becomes conductive, and the conductive protrusion in turn makes the electrode contacts conductive, thus energizing the LED placed in the detection slot. LEDs that meet the quality standards will light up, while those that do not will not. In addition, a voltage contact block and a voltmeter contact block are set adjacent to the detection protrusion to detect the voltage across the LED. If the LED is lit, a voltage will be generated across its terminals, allowing the system to determine whether the LED is lit.

[0007] In one specific implementation, the storage mechanism includes a storage box, the top of which is detachably equipped with a test tube holder. The test tube holder is a circular frame with a circular groove on it, and test tubes are placed in the groove.

[0008] In one specific implementation, a dispensing motor is fixedly installed inside the receiving box, and the dispensing motor is connected to the test tube holder.

[0009] By adopting the above technical solution, the test tube is used to store the qualified LED beads. The qualified LED beads are placed in a circular arrangement in the placement slots, so that the test tubes can also be arranged in a circular arrangement in the placement slots. Driven by the dispensing motor, the test tubes can be rotated.

[0010] In one specific implementation, the top of the test tube holder is provided with a discharge pipe, and a material distribution guide rail is connected to the discharge pipe. The material distribution guide rail has a groove to form a material distribution guide groove. The discharge pipe is set vertically, the material distribution guide rail is set downwardly, and the material distribution guide groove is connected to the outlet of the discharge pipe.

[0011] By adopting the above technical solution, when the test tube is rotated, it can pass through the dispensing guide rail one by one, so that the LED beads falling on the dispensing guide rail can fall into the test tube one by one.

[0012] In one specific implementation, a pressure-sensitive element is provided at the end of the material distribution guide channel, directly opposite the outlet of the discharge pipe.

[0013] By adopting the above technical solution and by setting the pressure-sensitive element, each falling LED bead can collide with the pressure-sensitive element and generate an electrical signal, thereby enabling the system to accurately collect the number of LED beads falling into each test tube, so that the LED beads can fall into each test tube evenly according to the predetermined number.

[0014] In one specific implementation, the storage mechanism further includes an NG suction tip, which is disposed adjacent to the detection electrode block.

[0015] In one specific implementation, the storage mechanism further includes an NG straw connected to the NG suction head, with an NG box provided at the opening of the NG straw.

[0016] In one specific implementation, the storage mechanism further includes a storage suction head, which is arranged adjacent to the NG suction head. The storage mechanism also includes a material storage pipe connected to the storage suction head and connected to the discharge pipe.

[0017] By adopting the above technical solution, the NG suction head is used to suck up unqualified parts into the NG box, and the storage suction head and storage suction tube are used to transfer qualified LED beads.

[0018] In one specific implementation scheme, the vibrating plate is connected to a single through groove, a negative pressure suction head is provided on the single through groove, the negative pressure suction pipe is connected to a discharge head through a pipe, the discharge head is placed above the detection disc, the discharge head has a material retention chamber and a side channel inside, the material retention chamber is vertically arranged in the discharge head, and the side channel communicates with the material retention chamber.

[0019] In one specific implementation, a rotating pusher is further provided between the material storage chamber and the bypass channel. The rotating pusher includes a ring-shaped rotating part and a pusher part integrally disposed on the periphery of the rotating part. The rotating part is connected to a pusher motor via gears.

[0020] By adopting the above technical solution, the material storage chamber is set up to temporarily store the LED beads, so that the LED beads can be arranged one by one in the material storage chamber in sequence. The setting of the pusher motor and the rotating pusher allows the LED beads in the material storage chamber to enter the detection slot one by one, so as to achieve the technical effect of quantitative feeding.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting two opposing detection electrode blocks and equipping them with electrode contacts and torsion springs, the LED can conduct electricity through the electrode contacts during the detection process, thereby making the electrode contacts conductive and illuminating the LED placed in the detection slot.

[0022] 2. By designing the material distribution guide rail and discharge pipe, the sequential falling of LED beads into the test tubes is further ensured. The use of pressure-sensitive elements enables the system to accurately collect information on the number of LED beads falling into each test tube.

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] In the description of the invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0028] This application discloses a rapid detection device for a patch spectrometer, referring to... Figure 1 and Figure 2 It includes a material feeding bin 1, a vibrating plate 2, a detection mechanism and a storage mechanism. The vibrating plate 2 is connected to a single channel 21. A negative pressure suction head 61 is provided on the single channel 21. The suction end of the negative pressure suction head 61 is facing the single channel 21. The vibrating plate 2 transports the lamp beads one by one through the single channel 21 with the electrode end facing upward.

[0029] Reference Figures 3 to 6 The negative pressure suction head 61 is connected to the discharge head 62 via a pipe. The discharge head 62 is positioned above the detection disc 31. The negative pressure suction head 61 can adsorb the LED beads on the single channel 21 one by one into the pipe and transport them to the discharge head 62 through the pipe. The discharge head 62 has a material storage chamber 621 and a bypass channel 622 inside. The material storage chamber 621 is vertically arranged inside the discharge head 62, and the bypass channel 622 is connected to the material storage chamber 621. The top of the material storage chamber 621 is connected to the pipe. The LED beads sucked in by the negative pressure suction head 61 will be stacked layer by layer in the material storage chamber 621. The diameter of the material storage chamber 621 is set to match the diameter of the LED beads, so that the LED beads can be arranged individually upwards in the material storage chamber 621. A rotating pusher 633 is also provided between the material storage chamber 621 and the bypass channel 622. The rotating pusher 633 includes a ring-shaped rotating part 634 and a pusher part 635 integrally disposed around the rotating part 634. The rotating part 634 is connected to a pusher motor 636 through a gear. The pusher motor 636 drives the rotating part 634 to rotate, thereby driving the pusher part 635 to rotate. The rotation path of the pusher part 635 is set at the connection between the bypass channel 622 and the material storage chamber 621, so that the pusher part 635 can push the lamp bead into the bypass channel 622 during rotation. The bypass channel 622 is tilted downward so that the lamp bead can slide out through the bypass channel 622.

[0030] The detection mechanism includes a detection disc 31 and detection components. A drive shaft 315 is vertically mounted in the center of the detection disc 31, and a disc drive motor 314 is connected to the bottom of the drive shaft 315. Multiple detection protrusions 311 are arranged in a ring on the outer side of the detection disc 31, and detection grooves 312 are formed on the top of the detection protrusions 311. The disc drive motor 314 can rotate the drive shaft 315, which in turn drives the detection disc 31 to rotate, allowing all detection grooves 312 to pass through the outlet of the bypass channel 622. When the detection groove 312 moves to directly below the outlet of the bypass channel 622, the push block 635 pushes out the LED bead, so that the end of the LED bead with the electrode faces downwards and falls into the detection groove 312.

[0031] Electrode contacts 313 are provided at the bottom of the detection slot 312. When the LED bead falls into the detection slot 312, the electrode contacts 313 contact the electrodes of the LED bead. The detection assembly includes two opposing detection electrode blocks 317, each with an electrode contact 318. There is a gap between the two electrode contacts 318, and the two electrode contacts 318 are connected to the detection electrode blocks 317 by a torsion spring 319. When the detection disc 31 rotates, the detection protrusion 311 passes between the two electrode contacts 318 and moves the electrode contacts 318. The torsion spring 319 returns the electrode contacts 318 to their original position after being moved. The two detection electrode blocks 317 are respectively connected to the positive and negative terminals of the power supply. When the electrode contact 318 contacts the detection protrusion 311, if the LED bead is of qualified quality, the electrode contact 318 will illuminate the LED bead in the detection slot 312 through the detection protrusion 311 and the electrode contacts 313. If the LED chip is of substandard quality, it will not light up. Each detection protrusion 311 is adjacent to a voltage contact block 316, which is fixedly mounted on the upper surface of the detection disk 31. A voltmeter contact block 320 is located on top of each voltage contact block 316. The voltage contact block 316 is connected in parallel with the LED chip and is used to detect the voltage across the LED chip, i.e., the voltage across the electrode contacts 313. The voltmeter contact block 320 has internal wires connected to the voltmeter, forming a circuit for detecting the voltage across the LED chip.

[0032] Reference Figure 1 , Figure 2 and Figure 7The storage mechanism includes a storage box 44, on the top of which a test tube holder 49 is detachably mounted. The test tube holder 49 is a circular frame with circular placement slots 50 arranged on it, in which test tubes are placed. A dispensing motor 51 is fixedly mounted inside the storage box 44 and connected to the test tube holder 49, driving the test tube holder 49 to rotate. A discharge pipe 45 is mounted on the top of the test tube holder 49, connected to a dispensing guide rail 46. The dispensing guide rail 46 has a groove forming a dispensing guide 47. The discharge pipe 45 is vertically mounted, while the dispensing guide rail 46 is inclined downwards. The dispensing guide 47 connects to the outlet of the discharge pipe 45. Because the test tube holder 49 is a circular frame, rotation allows the test tubes placed in the placement slots 50 to rotate one by one to below the dispensing guide 47. A pressure-sensitive element 48 is installed at the end of the dispensing guide trough 47, directly opposite the outlet of the discharge pipe 45. The receiving mechanism includes an NG suction head 321 and a storage suction head 322. Both the NG suction head 321 and the storage suction head 322 are located on the same side of the detection electrode block 317, adjacent to the detection electrode block 317, and adjacent to the storage suction head 322. The receiving mechanism also includes an NG suction tube 42 connected to the NG suction head 321 and a storage suction tube 41 connected to the storage suction head 322. The storage suction tube is connected to the discharge pipe 45. An NG box 43 is installed at the opening of the NG suction tube 42.

[0033] The implementation principle of this application embodiment is as follows: When testing the LED beads, the LED beads are placed in the feeding bin 1, which guides them into the vibrating plate 2. The vibrating plate 2 causes the electrode-bearing end of the LED beads to face upwards and pass through the single-pass groove 21 one by one. The negative pressure suction head 61 set at the single-pass groove 21 adsorbs the LED beads to the discharge head 62. The rotating pusher 633 set at the discharge head 62 pushes the LED beads out from the side channel 622 and into the detection groove 312. The end of the LED bead with electrodes that falls into the detection slot 312 will contact the electrode contact 313 at the bottom of the detection slot 312. When the detection protrusion 311 passes through the detection assembly, the electrode contacts 318 on the detection electrode block 317 will contact the detection protrusion 311, thereby testing whether the LED bead is lit. If the LED bead is lit, a voltage is generated across its two ends. The voltage across the LED bead can be detected by the voltage contact block 316 and the voltmeter contact block 320. When the LED bead is lit, the voltmeter reading changes, indicating whether the LED bead is lit. If the LED bead is lit, the detection disk 31 moves the lit LED bead to the next position, namely the NG pick-up head 321. If the NG suction head 321 is not working, the detection disc 31 will move the LED bead to the storage suction head 322. The storage suction head 322 will pick up the LED bead and pass it sequentially through the storage suction tube 41, the discharge tube 45, the distribution guide rail 46, and the distribution guide groove 47 before finally dropping it into the test tube for storage. If the LED bead fails the test, it will be sucked into the NG suction head 321 as it passes through the NG suction head 321 and fall into the NG box 43 through the NG suction tube 42.

[0034] Before passing through the material distribution guide 47, qualified LED beads fall directly from the discharge pipe 45 into the material distribution guide 47. Since the pressure sensing element 48 is located at the position where the LED beads fall, the pressure sensing element 48 can generate pressure sensing data. Each sensing indicates that an LED bead has fallen. Thus, according to the number of LED beads stored in each test tube, the LED beads can be distributed in a certain number, and the test tube fixing frame 49 can be rotated in conjunction with the material distribution motor 51 to ensure that the number of LED beads stored in each test tube is consistent.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
