Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of LED fluorescent powder preparation, in particular to a spraying mechanism for coating LED fluorescent powder. Background Art
[0002] LED lamp is a semiconductor material chip that emits light in an electric field. It is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver wire or gold wire. It is sealed with epoxy resin around to protect the internal core wire. Finally, the shell is installed, so the LED lamp has good shock resistance. In the LED lamp production line, there are many ways to use LED phosphors to achieve white light, such as coating yellow phosphors that can be excited by blue light on blue LED chips, coating green and red phosphors on blue LED chips, and coating three primary colors or multiple colors of phosphors on purple or ultraviolet LED chips. Among them, purple light has higher efficiency in converting white light, balanced spectral distribution, and relatively good color rendering index, which is of great significance for energy conservation and emission reduction and improving light quality.
[0003] The current LED phosphor spraying device cannot perform baking and shaping immediately after spraying is completed. The work needs to be performed separately, which is not only inefficient, but also leads to low phosphor excitation efficiency and uneven light output. In addition, since there is no cooling device after baking, it is not convenient to take it out quickly. In addition, during the operation of the coating machine, although the barrel of the coating machine moves horizontally with the slider, the phosphor colloidal solution in the barrel is still in a relatively stable state. If it is in a relatively stable state for a long time, the phosphor in the solution will precipitate, which will eventually affect the spraying uniformity.
[0004] Based on this, a spraying mechanism for coating LED fluorescent powder is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

[0028] The heating mechanism includes an upper shell 35, a fixed support plate is fixedly provided on one side of the upper shell 35, a first guide slide bar is slidably provided in a rectangular perforation at the upper end of the fixed support plate, the first guide slide bar is fixedly arranged inside a second fixed box 39, the second fixed box 39 is fixedly arranged on the upper end of the workbench 20, a second return spring 40 is fixedly provided between the upper end of the fixed support plate and the upper end of the second fixed box 39, a heating box 37 is communicated with the upper end of the upper shell 35, a heating tube 38 is fixedly provided inside the heating box 37, the heating box 37 is communicated with one end of the first hose, the first hose is communicated with the output end of the fan 43, the fan 43 is fixedly provided on the upper end of the workbench 20, a lower shell 36 is closely attached to the bottom end of the upper shell 35, the lower shell 36 is fixedly provided on the upper end of the workbench 20, a guide plate 41 is fixedly provided in the mounting groove at the bottom end of the heating box 37, a plurality of third push rods 42 are fixedly provided at the upper end of the placement rack 18 corresponding to the position of the guide plate 41, so that When in use, after the spraying tube 11 has finished spraying the LED chips inside the fixed mold 17, the first motor 19 is started, and the output end of the first motor 19 drives the placement rack 18 to rotate 90 degrees, so that the sprayed LED chips move to the bottom of the upper shell 35. In the process of the placement rack 18 driving the LED chips to move, one end of the third push rod 42 contacts the inclined surface of the guide plate 41, and then the third push rod 42 rotates with the placement rack 18, so that the upper shell 35 slides along the length direction of the first guide slide rod. When one end of the third push rod 42 contacts the bottom end of the guide plate 41, the upper shell 35 no longer moves. After the placement rack 18 rotates 90 degrees, one end of the third push rod 42 disengages from the bottom end of the guide plate 41, and under the action of the second return spring 40, the bottom end of the upper shell 35 is tightly attached to the upper end of the lower shell 36, and then the fan 43 is started.

[0029] The lower shell 36 is connected to one end of the fixed tube, and the other end of the fixed tube is connected to the liquid storage tank 45. The liquid storage tank 45 is fixedly arranged on the upper end of the workbench 20. When in use, a purification solution is added to the liquid storage tank 45. As the first hose continuously transports gas to the upper shell 35, the upper shell 35 and the lower shell 36 are combined into a closed space, so that the air inside the lower shell 36 enters the liquid storage tank 45 through the fixed tube. The solution purifies and discharges the gas after use, thereby reducing the diffusion of harmful gases generated when baking the LED chips.
[0030] A support frame is fixedly provided at the upper end of the workbench 20 corresponding to the position of the fixed mold 17, and a heat sink 44 is fixedly provided at one side of the support frame corresponding to the position above the fixed mold 17. The heat sink 44 is connected to one end of the second hose, and the other end of the second hose is connected to the output end of the fan 43. When in use, when the LED chip rotates to the bottom of the heat sink 44 after baking, the fan 43 transports gas to the inside of the heat sink 44 through the second hose to the output end, and the gas inside the heat sink 44 can dissipate the heat of the LED chip inside the fixed mold 17.
[0031] The feeding mechanism includes a second storage box 16, which is fixedly arranged at the upper end of the first storage box 15, and a discharge pipe at the bottom end of the second storage box 16 is connected to the inside of the first storage box 15. A baffle plate 30 is tightly arranged at one end of the discharge pipe at the bottom end of the second storage box 16, and the baffle plate 30 is slidably arranged in a rectangular through-hole at one end of the first storage box 15. A circular through-hole is arranged at the upper end of the baffle plate 30 corresponding to the position of the discharge pipe, and a tension spring 31 is fixedly arranged between one side of the fixed plate at the upper end of the baffle plate 30 and the outer side of the first storage box 15, a limit plate 29 is slidably arranged in the limit groove at the upper end of the baffle plate 30, and a support frame is slidably arranged on the limit plate 29, and the support frame is fixedly arranged on the first storage box 15, and a first baffle plate 29 is fixedly arranged on one side of the limit plate 29. A guide block 27, the upper end of the first guide block 27 is fixedly connected to the output end of the spring telescopic rod 28, the spring telescopic rod 28 is fixedly arranged at the bottom end of the support frame, the inclined surface of the first guide block 27 is in close contact with one end of the first push rod 26, the first push rod 26 is fixedly arranged at the upper end of the first sliding block 24, the first sliding block 24 is slidably arranged inside the fixed mounting tube, the fixed mounting tube is fixedly arranged on the first storage box 15, a first return spring 25 is fixedly arranged between one side of the first sliding block 24 and one side inside the fixed mounting tube, a floating ring 23 is slidably arranged inside the first storage box 15, a second guide slide rod is slidably arranged in two rectangular perforations at the upper end of the floating ring 23, and the two ends of the second guide slide rod are respectively fixedly arranged on the upper and lower surfaces inside the first storage box 15 At the lower two ends, a second guide block 32 is fixedly provided on both sides of the baffle plate 30, and a second push rod 33 is tightly provided on the inclined surface of the bottom end of the second guide block 32, and the two second push rods 33 are fixedly provided on the upper end of the floating ring 23. When in use, when the staff adds spray liquid into the second storage box 16 in advance, and then the spray liquid in the first storage box 15 is used, the liquid level in the first storage box 15 drops, and the floating ring 23 always floats on the surface of the spray liquid. When the floating ring 23 drops to the corresponding position of one end of the first sliding block 24, the floating ring 23 squeezes the first sliding block 24, so that the first sliding block 24 slides into the fixed installation tube, and at the same time, the first sliding block 24 drives the first push rod 26 to move, and under the action of the spring telescopic rod 28, the first guide The inclined surface of the block 27 is always in close contact with one end of the first push rod 26, and the first guide block 27 drives the limit plate 29 to slide. When the first sliding block 24 no longer moves, one end of the limit plate 29 disengages from the limit groove, and the baffle plate 30 slides under the action of the tension spring 31. When the circular perforation on the upper end of the baffle plate 30 is aligned with one end of the discharge pipe, the spraying liquid inside the second storage box 16 enters the first storage box 15, thereby reducing the time for adding the spraying liquid. Subsequently, the liquid level inside the first storage box 15 increases, and the floating ring 23 returns to its initial position. During this process, the second push rod 33 at the upper end of the floating ring 23 pushes the baffle plate 30 back to its initial position through the second guide block 32, thereby closing one end of the discharge pipe, and then the limit plate 29 fixes the baffle plate 30 again.
[0032] A counterweight ring is fixedly provided at the bottom end of the floating ring 23. When in use, when the floating ring 23 contacts the first sliding block 24, the weight of the floating ring 23 is increased under the action of the counterweight ring.
[0033] A pressure sensor 34 is provided at the bottom end of the second storage box 16. When in use, when the spray liquid in the second storage box 16 is added to the first storage box 15, due to the lack of liquid pressure, the pressure sensor 34 is electrically connected to the external control, thereby notifying the staff to add spray liquid to the second storage box 16.
[0034] Example 2
[0035] The difference from Example 1 is that a mounting shaft 21 is rotatably provided in the mounting groove at the bottom end of the first storage box 15, and the other end of the mounting shaft 21 is rotatably provided in the mounting hole at the upper end of the second storage box 16, one end of the mounting shaft 21 is fixedly connected to the output end of the second motor 22, and the second motor 22 is fixedly provided at the upper end of the second storage box 16, and a plurality of stirring rods are fixedly provided on the mounting shaft 21 at positions corresponding to the positions of the first storage box 15 and the second storage box 16. When in use, it is convenient to stir the spray liquid inside the first storage box 15 and the second storage box 16 to prevent the precipitation of the fluorescent powder.
[0036] The above embodiment discloses a spraying mechanism for coating LED fluorescent powder, wherein after the spraying barrel 11 finishes spraying the LED chips inside the fixed mold 17, the first motor 19 is started, and the output end of the first motor 19 drives the placement rack 18 to rotate 90 degrees, so that the sprayed LED chips move to the bottom of the upper shell 35. In the process of the placement rack 18 driving the LED chips to move, one end of the third push rod 42 contacts the inclined surface of the guide plate 41, and then the third push rod 42 rotates with the placement rack 18, so that the upper shell 35 slides along the length direction of the first guide slide bar. When one end of the third push rod 42 contacts the bottom end of the guide plate 41, the upper shell 35 no longer moves. After the placement rack 18 rotates 90 degrees, the third push rod 42 is separated from the guide plate 41. At the bottom end of the plate 41, under the action of the second return spring 40, the bottom end of the upper shell 35 is tightly attached to the upper end of the lower shell 36, and then the fan 43 is started. The fan 43 transports air to the inside of the heating box 37 through the first hose, and the heating tube 38 heats the air, thereby baking the LED chip. As the first hose continuously transports gas to the inside of the upper shell 35, since the upper shell 35 and the lower shell 36 are combined into a closed space, the air inside the lower shell 36 enters the liquid storage tank 45 through the fixed pipe, and the solution purifies the gas after use and discharges it. After the LED chip is baked, when it rotates to the bottom of the heat sink 44, the fan 43 transports gas to the inside of the heat sink 44 through the second hose to the output end, and the inside of the heat sink 44 The gas can dissipate heat for the LED chip inside the fixed mold 17. Then the staff removes the processed LED chip. The staff adds spray liquid inside the second storage box 16 in advance. Then the spray liquid inside the first storage box 15 is used. The liquid level inside the first storage box 15 drops, and the floating ring 23 always floats on the surface of the spray liquid. When the floating ring 23 drops to the position corresponding to the position of one end of the first sliding block 24, the floating ring 23 squeezes the first sliding block 24, so that the first sliding block 24 slides into the fixed installation tube. At the same time, the first sliding block 24 drives the first push rod 26 to move. Under the action of the first reset spring 25, the inclined surface of the first guide block 27 is always in close contact with one end of the first push rod 26. At the same time, the first guide block 2 7 drives the limit plate 29 to slide. When the first sliding block 24 no longer moves, one end of the limit plate 29 is separated from the limit groove. Under the action of the tension spring 31, the baffle plate 30 slides. When the circular perforation on the upper end of the baffle plate 30 is aligned with one end of the discharge pipe, the spray liquid inside the second storage box 16 enters the first storage box 15, thereby reducing the time for adding the spray liquid. As a result, the liquid level inside the first storage box 15 increases, and the floating ring 23 returns to the initial position. During this process, the second push rod 33 on the upper end of the floating ring 23 pushes the baffle plate 30 back to the initial position through the second guide block 32, thereby closing one end of the discharge pipe. Then the limit plate 29 fixes the baffle plate 30 again, and at the same time drives the mounting shaft 21 to rotate through the second motor 22.The mounting shaft 21 facilitates stirring the spray liquid inside the first storage box 15 and the second storage box 16 through a plurality of stirring rods to prevent the phosphor from settling.
