[0035] The storage component 6 is disposed on the top of the workbench 1. The storage component 6 includes a second spring slide rod 61, a second connecting block 62, and a storage tank 63.
[0036] The workbench 1 is a plate with four support legs fixed to the bottom for support and fixation. The screening component 2 rotates to screen phosphors of different particle sizes. The first auxiliary component 3 connects to realize the vibration of the screening component 2. The support and limiting component 4 supports the storage component 6 and drives the storage tank 63 to move up and down. The drive component 5 drives the moving parts of the device. The storage component 6 is connected to the screening disc 22 to realize the screening of phosphors.
[0037] The rotating plate 21 is movably connected to the top of the workbench 1, the screening disc 22 is fixedly installed on the surface of the rotating plate 21, and the striking block 23 is movably connected to the outer surface of the screening disc 22.
[0038] The rotating plate 21 is cross-shaped and is rotatably mounted on the top of the workbench 1. There are four screening discs 22, which are fixedly connected to the four corners of the rotating plate 21, and their surfaces are connected with different mesh sizes. The screening discs 22 are rotated to the bottom of the storage tank 63 to achieve screening of different particle sizes of fluorescent powder. There are two striking blocks 23, which are rotatably connected to the left and right ends of the top of the workbench 1. When the two striking blocks 23 rotate, they can strike the screening discs 22, causing the rotating plate 21 and the screening discs 22 to shake left and right.
[0039] The sliding groove 31 is formed inside the workbench 1, the first spring slide rod 32 is fixedly connected inside the sliding groove 31, the first connecting block 33 is fixedly connected to the bottom of the rotating plate 21, and the rotating plate 21 is movably connected to the surface of the first spring slide rod 32.
[0040] The sliding groove 31 is located at the center of the screening assembly 2. The first spring slide rod 32 is a rod with a spring movably sleeved on its outer surface. The two ends of the rod are fixedly connected to the inner surface of the sliding groove 31. The first connecting block 33 is movably embedded inside the sliding groove 31 and slidably sleeved on the outer surface of the rod. The center of the rotating plate 21 is rotatably connected to the top surface of the first connecting block 33. Thus, when the rotating plate 21 shakes, it cooperates with the spring in the first spring slide rod 32 to realize the vibration of the rotating plate 21 and the screening disc 22.
[0041] The support frame 41 is fixedly connected to the top of the workbench 1, the limiting rod 42 is fixedly connected to the inner surface of the support frame 41, and the movable seat 43 is movably connected to the surface of the limiting rod 42.

When the second drive motor 53 is started, the threaded rod 54 rotates, and the movable seat 43 is limited by the limiting rod 42, thereby realizing the up and down movement of the movable seat 43.
[0045] The second spring slide rod 61 is fixedly connected to the upper and lower surfaces of the movable seat 43, the second connecting block 62 is movably connected to the surface of the second spring slide rod 61, and the storage tank 63 is fixedly connected to the other end of the second connecting block 62.
[0046] The second spring slide rod 61 is composed of a spring that is movably sleeved on the surface of a rod. The connecting rod is fixedly connected to the upper and lower inner surfaces of the second spring slide rod 61. The two second connecting blocks 62 are respectively movably connected to the surfaces of the connecting rods on the surfaces of the two second spring slide rods 61.

Then, pour the fluorescent powder into the storage tank 63 and start the first drive motor 52 to drive the two pulleys to drive the two striking blocks 23 to rotate synchronously and strike the two screening discs 22 connected to them. The screening disc 22 causes the storage tank 63 to shake at a high height, and the vibration of the storage tank 63 is achieved through the first spring slide rod 32 and the second spring slide rod 61, thereby realizing the screening of the fluorescent powder.
