Description

Technical Field

[0001] The utility model relates to the field of lamp bead production and preparation, in particular to a lamp bead chip removing device. Background Art

[0002] LED lamp beads refer to small devices that use LED (light-emitting diode) as a light source. LED is a solid-state light-emitting device with the characteristics of high brightness, low energy consumption, and long life, so it is widely used in lighting, display, and indication. LED lamp beads are usually composed of multiple LED chips that are processed in a small package and connected to a circuit board.

[0003] When preparing LED lamp beads, the preparation process includes solid crystal, wire welding, glue dispensing, blanking, light splitting, material mixing, and tape delivery. Among them, the blanking process requires the lamp beads to be peeled off from the bracket into individual lamp beads. This process is achieved through external force destruction. Therefore, during the blanking process, the PPA (polyphthalamide) resin on the brackets on both sides of the lamp beads is easily peeled off due to the card points on both sides of the lamp beads, resulting in PPA resin dust. In the above-mentioned LED preparation process, the PPA resin dust mixed in the lamp beads cannot be removed, which will lead to problems such as the LED lamp bead pins cannot be tinned or cold soldered during the subsequent lamp bead patching due to dust problems, affecting the use of the display screen. Therefore, in actual production, the dust will be removed manually after blanking, but due to the additional dust removal process, the production process of the lamp beads is increased in disguise, which reduces the production efficiency of the lamp beads. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a lamp bead dust removal device, aiming to solve the problem in the prior art that an additional dust removal process is required to clear the dust attached to the lamp beads, resulting in low lamp bead production efficiency.

[0005] The lamp bead dust removing device proposed in the utility model comprises an inner barrel for placing lamp beads, an outer barrel sleeved on the outer side of the inner barrel, and a connecting piece arranged at the bottom of the inner barrel for connecting the inner barrel and the outer barrel, wherein a plurality of evenly distributed filter holes are arranged at the bottom of the inner barrel, and a stirring baffle is extended inwardly from the side wall of the inner barrel, and the cross-sectional area of ​​the stirring baffle gradually increases from the top to the bottom. When in use, the inner barrel is driven to rotate relative to the outer barrel or the inner barrel and the outer barrel are driven to rotate synchronously by external equipment, so that the stirring baffle stirs the lamp beads in the inner barrel and causes the dust attached to the lamp beads to fall off and enter the outer barrel through the filter holes.

[0006] The above-mentioned lamp bead dust removal device is provided with an inner barrel and stirring baffles inside the inner barrel. After the lamp beads are sorted, they are stirred and mixed in the inner barrel. Then, an outer barrel is arranged outside the inner barrel, filter holes are arranged at the bottom of the inner barrel, and the inner barrel and the outer barrel are connected to each other through a connecting member, so that an external device can drive the inner barrel to rotate relative to the outer barrel or drive the inner barrel and the outer barrel to rotate together. Thus, while the stirring baffles rotate for mixing materials, the dust attached to the surface of the lamp beads is separated from the lamp beads and enters the outer barrel through the filter holes, thereby realizing the function of dust removal. Furthermore, the two processes of wheel mixing and dust removal are achieved in one step, greatly improving the production efficiency of lamp beads and avoiding the influence of dust on the production of lamp beads. In addition, by gradually changing the cross-sectional area of the stirring baffles, the lamp beads in the stirring barrel are more likely to move upward under the stirring action and then move downward under the action of gravity, thereby improving the stirring effect and making the dust more likely to fall from the filter holes. Therefore, the present utility model solves the problems of low cleaning efficiency of the surface fluff of lamp beads in the prior art and the influence on the workshop environment.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] See also Figures 1 to 3 , shown is a lamp bead chip removal device in the first embodiment of the utility model, comprising an inner barrel 10 for placing lamp beads, an outer barrel 20 sleeved outside the inner barrel 10, and a connecting piece 30 arranged at the bottom of the inner barrel 10 for connecting the inner barrel 10 and the outer barrel 20, wherein:

[0030] A plurality of evenly distributed filter holes 11 are provided at the bottom of the inner barrel 10, and a stirring baffle 12 is extended inwardly from the side wall of the inner barrel 10, and the cross-sectional area of ​​the stirring baffle 12 gradually increases from the top to the bottom. When in use, the inner barrel 10 is driven by an external device to rotate relative to the outer barrel 20 or the inner barrel 10 and the outer barrel 20 rotate synchronously, so that the stirring baffle 12 stirs the lamp beads of the inner barrel 10, and causes the dust attached to the lamp beads to fall off and enter the outer barrel 20 through the filter holes 11.

[0031] It can be understood that by setting the inner barrel 10 and setting the stirring baffle 12 in the inner barrel 10, after the lamp beads are split, they are stirred and mixed in the inner barrel 10, and then by setting the outer barrel 20 on the outside of the inner barrel 10, and setting the filter hole 11 at the bottom of the inner barrel 10, and by setting the connecting piece 30 to connect the inner barrel 10 and the outer barrel 20 to each other, the external device can drive the inner barrel 10 to rotate relative to the outer barrel 20, or drive the inner barrel 10 and the outer barrel 20 to rotate together, so that the stirring baffle 12 rotates to mix the material, and the dust attached to the surface of the lamp beads is separated from the lamp beads and enters the outer barrel 20 through the filter hole 11, thereby realizing the function of dust removal, and then the two processes of mixing the material and removing the dust are realized in one step, which greatly improves the production efficiency of the lamp beads and avoids the influence of dust on the production of lamp beads. In addition, by gradually changing the cross-sectional area of ​​the stirring baffle 12, the lamp beads in the stirring barrel are more likely to move upward under the stirring action, and then move downward under the action of gravity, thereby improving the stirring effect and making it easier for dust to fall from the filter hole 11. Therefore, the utility model solves the problem of low cleaning efficiency of the lamp bead surface hair debris and affecting the workshop environment in the prior art.

[0032] It should be noted that during the production process, the lamp beads need to be split and divided into different grades. However, even at the same grade, due to the instrument deviation of each splitting device itself, there are still slight deviations in the brightness of the lamp beads of the same grade. Therefore, the lamp beads of the same grade need to be mixed and evenly mixed to ensure the uniformity of the light output after the lamp beads are mounted.

[0033] By way of example and not limitation, in some optional embodiments, the connecting member 30 includes a connecting column 31 disposed at the bottom of the inner barrel 10 and a connecting shell 32 disposed on the outer barrel 20, the connecting shell 32 is sleeved on the connecting column 31, the connecting column 31 includes a cylindrical portion 311 connected to the inner barrel 10 and a prism portion 312 away from the inner barrel 10, the connecting shell 32 is adapted to the prism portion 312 and sleeved on the prism portion 312, the cylindrical portion 311 is a hollow structure and one end is connected to the interior of the inner barrel 10, and the side of the cylindrical portion 311 is provided with a filter hole 11. By providing the connecting column 31 and the connecting shell 32, and making the prism portion 312 of the connecting column 31 adapted to the connecting shell 32, the external setting can drive the outer barrel 20 to rotate, thereby driving the inner barrel 10 to rotate, thereby achieving the mixing and dust removal function inside the inner barrel 10. In addition, by providing a hollow cylindrical portion 311, a filter hole 11 can also be provided on the top plate of the connecting column 31, thereby improving the dust filtering effect. The dust enters the cylindrical portion 311 through the filter hole 11 on the top of the cylindrical portion 311, and is thrown into the outer barrel 20 through the filter hole 11 on the side of the cylindrical portion 311 under the action of centrifugation, thereby causing the dust to gather on the outside for easy cleaning.

[0034] Furthermore, a stopper 14 is extended outward from the outer side of the inner barrel 10, and a stopper 21 adapted to the stopper 14 is provided on the inner side of the outer barrel 20. By providing the stopper 14 on the outer side of the inner barrel 10 and the stopper 21 adapted to the stopper 14 on the inner side of the outer barrel 20, the outer barrel 20 can drive the inner barrel 10 to rotate through the cooperation of the stopper 21 and the stopper 14, thereby allocating the force of the connecting column 31, ensuring the stirring effect of the inner barrel 10, and improving the service life of the connecting piece 30.

[0035] Specifically, the side wall of the inner barrel 10 is provided with a plurality of stirring baffles 12, and the plurality of stirring baffles 12 are equidistantly distributed along the circumferential direction of the axis of the inner barrel 10. The stirring efficiency in the barrel is improved by providing a plurality of stirring baffles 12. In addition, in a specific implementation, the stirring baffles 12 can also be tilted to be arranged so that the tilting direction of the stirring baffles 12 is consistent with the stirring direction to improve the stirring effect. In addition, during the specific stirring, the lamp beads will submerge the stirring baffles 12 to ensure the stirring efficiency of the stirring baffles 12.

[0036] See also Figures 4 to 6 , shown is a lamp bead chip removal device in the second embodiment of the utility model. The difference between the second embodiment and the first embodiment is that the connecting member 30 is provided with a transmission shaft 33 at the bottom of the inner barrel 10 and a bearing 34 provided on the outer barrel 20. The transmission shaft 33 includes a hollow portion 331 connected to the inner barrel 10 and a solid portion 332 away from the inner barrel 10. The hollow portion 331 is connected to the inner wall of the inner barrel 10, and a filter hole 11 is provided on the side of the hollow portion 331. Specifically, by providing a transmission shaft 33 and a transmission shaft 33 bearing, and in a specific implementation, the transmission shaft 33 extends to the outside of the outer barrel 20, so that the inner barrel 10 can be driven to rotate relative to the outer barrel 20 through the transmission shaft 33 by an external device, thereby achieving a stirring and filtering effect of the inner barrel 10. In addition, by providing the hollow portion 331 and the filter hole 11 on the side of the hollow portion 331, the filter hole 11 can also be provided on the top plate of the transmission shaft 33 to improve the filtering effect. By providing different connecting pieces 30, the lamp bead chip removal device can be connected to different external devices, thereby improving the adaptability of the lamp bead chip removal device.

[0037] In addition, the lamp bead dust removal device also includes a stirring assembly 40, which includes a stirring component 41 and a connecting component 42 suspended in the inner barrel 10, one end of the connecting component 42 is connected to the stirring component 41, and the other end is connected to the outer barrel 20 and the inner barrel 10, so that the stirring component 41 is suspended in the inner barrel 10. By setting the stirring assembly, the barrel stirring assembly can also be attached with a stirring baffle 12 to stir the lamp beads in the barrel to improve the stirring effect, and the addition of the stirring component 41 makes the contact frequency between the lamp beads and the stirring member higher, thereby making the separation effect between the dust attached to the lamp beads and the lamp beads better.

[0038] Furthermore, the stirring component 41 includes a stirring shaft 411 connected to the connecting component 42, and a stirring blade 412 arranged on the stirring shaft 411, an air hole is arranged at the bottom of the stirring blade 412, the stirring shaft 411 is a hollow structure and is connected to the air hole, and one end of the stirring shaft 411 is connected to an external air supply device. In a specific implementation, by arranging an air hole at the bottom of the stirring blade 412, and supplying air to the hollow stirring shaft 411 through the air supply device and spraying it through the air hole, the dust is easier to filter from the filter hole 11. In addition, the air supply device can also provide gas at a certain temperature to reduce the electrostatic effect between the dust and the lamp beads, so that the dust and the lamp beads are easier to separate.

[0039] Specifically, the connecting component 42 includes a flat plate 421, a connecting rod 422 disposed between the inner barrel 10 and the outer barrel 20, and a connecting plate 423 for connecting the connecting rod 422 and the flat plate 421. The flat plate 421 is provided with a mounting hole 424 adapted to the stirring shaft 411. The connecting rod 422 is provided with a gear 425 on the side away from the connecting plate 423. The outer side of the inner barrel 10 and the inner side of the outer barrel 20 are both provided with a gear portion 13 adapted to the gear 425. In a specific implementation, the gear portion 13 is driven to cooperate with the gear 425 by the rotation of the inner barrel 10, so as to drive the flat plate 421 to rotate, and then drive the stirring shaft 411 to rotate. Since the gear 425 and the gear portion 13 constitute a planetary gear 425 structure, the rotation speeds of the inner barrel 10 and the stirring shaft 411 are different, so that a speed difference is formed between the two, and the two do not rotate synchronously, and then rotate relatively synchronously. The stirring paddle with a speed difference has a better stirring effect on the lamp beads in the inner barrel 10. In addition, the inner barrel 10 may be driven to rotate in the reverse direction by driving the connecting rod 422 to rotate and fix the outer barrel 20, without being limited to driving the outer barrel 20 or the inner barrel 10 to rotate by an external device.

[0040] Further, the mounting hole 424 is a threaded hole, and a reciprocating wire rod 413 adapted to the threaded hole is provided on the stirring shaft 411. In addition, in a specific implementation, a reciprocating wire rod 413 can also be provided on the stirring shaft 411, so that the stirring shaft 411 can move up and down relative to the flat plate 421 to improve the stirring effect.

[0041] In addition, a plurality of stirring blades 412 are evenly distributed along the axis of the stirring shaft 411 to form a stirring blade 412 group, and a plurality of stirring blade 412 groups are evenly distributed along the length direction of the stirring shaft 411. By providing a plurality of stirring blades 412, the contact area and contact frequency between the stirring blades 412 and the lamp beads are increased, which improves the stirring effect and the separation efficiency of the dust and the lamp beads.

[0042] In summary, the lamp bead chip removal device in the above-mentioned embodiment of the utility model is provided with an inner barrel 10, and a stirring baffle 12 is provided in the inner barrel 10, so that after the lamp bead is split, it is stirred and mixed in the inner barrel 10, and then an outer barrel 20 is provided on the outside of the inner barrel 10, and a filter hole 11 is provided at the bottom of the inner barrel 10, and the inner barrel 10 and the outer barrel 20 are connected to each other by providing a connecting piece 30, so that the inner barrel 10 can be driven by an external device to rotate relative to the outer barrel 20, or the inner barrel 10 and the outer barrel 20 can be driven to rotate together, so that the stirring baffle 12 rotates to mix the material, and the dust attached to the surface of the lamp bead is separated from the lamp bead and enters the outer barrel 20 through the filter hole 11, thereby realizing the function of dust removal, and then the two processes of mixing the material and removing the dust are realized in one step, which greatly improves the production efficiency of the lamp bead and avoids the influence of dust on the production of the lamp bead. In addition, by gradually changing the cross-sectional area of ​​the stirring baffle 12, the lamp beads in the stirring barrel are more likely to move upward under the stirring action, and then move downward under the action of gravity, thereby improving the stirring effect and making it easier for dust to fall from the filter hole 11. Therefore, the utility model solves the problem of low cleaning efficiency of the lamp bead surface hair debris and affecting the workshop environment in the prior art.
