LED lights have good shock resistance. Currently, the light transmittance quality inspection method used in the mass production of cylindrical LED beads involves manual sampling, which results in a high defect rate. Therefore, solving this problem is a key objective of this invention. Utility Model Content

Detailed Implementation
[0024] The cylindrical LED bead sorting machine of this utility model includes a frame 1, a worktable 2 mounted on the frame 1, a conveyor belt mechanism 3 mounted on the worktable 2, a sorting disc assembly 4 mounted on the worktable 2 and connected to the conveyor belt mechanism 3, a nozzle assembly 5 mounted on the frame 1 and located directly above the sorting disc assembly 4, and an optical detector 6 mounted on the worktable 2 and facing the sorting disc assembly 4. A rotary drive device 41 is mounted on the frame 1, located below the sorting disc assembly 4 and driving the sorting disc assembly 4 to rotate. The sorting disc assembly 4 includes a disc-shaped sorting disc 42. Several receiving cavities 43 are evenly distributed around the circumference of the sorting disc 42 for the cylindrical LED beads to be sorted to be placed into. After the sorting disc 42 rotates and is detected by the optical detector 6, qualified products and products with unqualified light transmittance among the cylindrical LED beads to be sorted are blown off by the nozzle assembly 5 into the corresponding material frame on the worktable 2 (the material frame is not shown in the diagram). By employing the above structure, the optical inspection instrument 6 inspects each of the cylindrical LED beads to be sorted on the sorting disc assembly 4. The qualified and non-qualified cylindrical LED beads are then blown onto the worktable 2 by the nozzle assembly 5. Compared to previous methods, this invention efficiently determines the qualification of all cylindrical LED beads to be inspected and sorts them according to different specifications.
[0025] The aforementioned conveyor belt mechanism 3 is disposed on one side of the sorting disc assembly 4 on the workbench 2, and the conveyor belt mechanism 3 and the receiving cavity 43 on the sorting disc 42 are at the same horizontal height. The rotary drive device 41 of this utility model is disposed on the frame 1 via a drive bracket; the sorting disc assembly 4 includes a sorting disc 42 and a vibrating disc 44 located below the sorting disc 42 and coaxial with the sorting disc 42. A lifting drive device (not shown in the figure) is disposed on the vibrating disc 44 and drives the vibrating disc 44 to rise and fall. The lifting drive device is disposed on the drive bracket.
[0026] In this invention, the cylindrical LED beads to be sorted, placed in the receiving cavity 43 of the sorting disk 42, are located on the vibrating disk 44. When the defective cylindrical LED beads are blown off by the nozzle assembly 5, the lifting drive device drives the vibrating disk 44 to move downward relative to the sorting disk 42. The downward movement of the vibrating disk 44 separates it from the sorting disk 42, thus preventing the defective cylindrical LED beads from getting stuck and slipping out of the receiving cavity 43 at the moment they are blown off by the nozzle assembly 5. To prevent the displacement distance of the vibrating disk 44 relative to the sorting disk 42 from being too large and affecting the normal operation of the sorting disk 42, the downward movement of the vibrating disk 44 relative to the sorting disk 42 by the lifting drive device is 1 / 5 to 1 / 3 of the height of the cylindrical LED beads to be sorted.
[0027] The aforementioned rotary drive device 41 is a rotary motor, and the lifting drive device is a lifting hydraulic cylinder or a lifting air cylinder. The nozzle assembly 5 of this utility model includes a nozzle bracket 51 mounted on the frame 1, a mounting plate 52 fixedly mounted on the nozzle bracket 51, a connecting column 53 fixedly mounted below the mounting plate 52, a nozzle mounting plate 54 located at the lower end of the connecting column 53, and nozzles 55 mounted on the nozzle mounting plate 54 directly opposite the receiving cavity 43 of the sorting disc 42. The nozzles 55 are connected to an air source. The nozzle bracket 51 is a gantry structure mounted on the frame 1. The nozzle mounting plate 54 has several flashes 56 for mounting the nozzles 55, and each flash has mounting holes for inserting the corresponding nozzle 55. The aforementioned optical detector 6 is a transmittance tester.
[0028] To further improve the working efficiency of this utility model, at least one sorting disk assembly 4 is provided on the workbench 2, and the number of sorting disk assemblies 4 is the same as the number of nozzle assemblies 5 and the number of optical detectors 6.
[0029] In addition to separating qualified and unqualified products, this utility model can also separate cylindrical LED beads of different color temperatures and wavelengths among qualified products. Specifically, among the cylindrical LED beads 7 to be separated, qualified products include cylindrical LED beads of different colors and wavelengths. Using an optical detector, cylindrical LED beads of different colors and wavelengths are blown off by the nozzle assembly 5 onto the corresponding material frame on the worktable 1, which is not shown in the material frame diagram.
