Description

Technical Field

[0001] The utility model relates to the technical field of LEDs, in particular to a lamp bead hair removal and chip dropping device and a lamp bead dropping system. 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, they need to be dropped from a whole bracket through a blanking machine after packaging and baking. The lamp bead bracket will move through the conveyor track and pass through the tool to separate the lamp bead from the bracket, thereby completing the blanking of the lamp bead. However, since the card point of the bracket is plastic, a lot of plastic debris will be generated in this process and mixed with the lamp beads, and then there is a problem that the hair debris sticks to the surface of the lamp bead, resulting in a poor appearance of the lamp bead. In the prior art, after the lamp beads are blanked, the surface of the lamp beads is usually cleaned manually with the help of a fan, etc., and the cleaning efficiency is low. Due to the accumulation of lamp beads, a larger wind is required to separate the hair debris from the lamp beads. If suction is used, the lamp beads will be sucked away. Therefore, the lamp beads are usually blown in a perforated container, which makes it easy for the hair debris to be blown and spread in the workshop, affecting the workshop environment. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a lamp bead hair removal and chip dropping device and a lamp bead dropping system, aiming to solve the problem of low efficiency of lamp bead surface hair removal and chip dropping in the prior art and affecting the workshop environment.

[0006] The above-mentioned lamp bead hair removal and debris dropping device is provided with a debris removal bin so that the lamp bead enters the debris removal bin for debris removal after being dropped, wherein a fan is provided on one side of the debris removal bin so that when the lamp bead falls down in the debris removal bin, the hair on the surface of the lamp bead will be separated from the lamp bead under the blowing of the fan. In addition, a filter is provided in the debris removal bin, and a material dropping pipe is provided in the middle of the filter. After the hair and the lamp bead are separated, they will continue to move downward in the debris removal bin through the filter and be discharged to a designated position, while the lamp bead is transported to an external material box through the material dropping pipe above the filter. In addition, there is a situation where the hair is still attached to the lamp bead after the fan blows, and the rolling of the lamp bead on the filter will also separate the hair from the lamp bead and fall from the filter, thereby performing a secondary separation on the lamp bead to ensure the separation effect between the lamp bead and the hair. In addition, since the debris removal is carried out in the debris removal bin, the hair generated by the debris removal is directed to a designated position, thereby avoiding the situation where the hair affects the workshop environment. Therefore, the utility model solves the problem in the prior art that the cleaning efficiency of hair debris on the surface of lamp beads is low and affects the workshop environment.

Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] See also Figure 1 to Figure 2 , shown is a lamp bead hair removal and chip dropping device in an embodiment of the utility model, comprising a drop bin 10 arranged between the conveying tracks and a chip removal bin 20 arranged at the bottom of the drop bin 10 and connected to the drop bin 10, wherein:

[0026] The chip removal bin 20 includes a shell 21, a filter element 30 arranged in the shell 21 to separate the shell 21 into an upper and lower part, a drop pipe 40 arranged in the middle of the filter element 30 for transferring lamp beads, and a fan 50 arranged on one side of the shell 21. The fan 50 is used to separate the hair debris from the lamp beads by blowing air, and the filter element 30 is used to filter the hair debris to the lower part of the shell 21.

[0027] It can be understood that by setting up the chip removal bin 20, the lamp beads enter the chip removal bin 20 for chip removal after they are dropped, wherein a fan 50 is provided on one side of the chip removal bin 20, so that in the process of the lamp beads falling down in the chip removal bin 20, under the blowing of the fan 50, the hair debris on the surface of the lamp beads will be separated from the lamp beads. In addition, a filter 30 is also provided in the chip removal bin 20, and a material dropping pipe 40 is provided in the middle of the filter 30. After the hair debris is separated from the lamp beads, it will continue to move downward in the chip removal bin through the filter 30 and be discharged to the designated position, while the lamp beads are transported to the external material box through the material dropping pipe 40 above the filter 30. In addition, there is a situation where the hair debris is still attached to the lamp beads after the blowing of the fan 50. The rolling of the lamp beads on the filter 30 will also separate the hair debris from the lamp beads and fall from the filter 30, thereby performing a secondary separation on the lamp beads to ensure the separation effect between the lamp beads and the hair debris. In addition, since the debris removal is carried out in the debris removal chamber 20, the debris generated by the debris removal is directed to a designated location, thereby preventing the debris from affecting the workshop environment. Therefore, the utility model solves the problem of low efficiency in cleaning debris on the surface of the lamp beads and affecting the workshop environment in the prior art.

[0028] In addition, the filter element 30 includes two symmetrically inclined mesh belts, so that the height of the filter element 30 gradually increases from the middle to the two ends. The bottom of the drop bin 10 is provided with a drop port 11 adapted to the top feed port 22 of the chip removal bin 20, and the drop port 11 is directly opposite to the middle of the mesh belt near the fan 50. Specifically, by setting the filter element 30 as a mesh belt, the lamp beads will bounce on the mesh belt when they fall, which can not only prevent the lamp beads from colliding with hard parts and being damaged, but also allow the lamp beads to shake off the hair debris when they bounce, thereby achieving a separation effect. In addition, by setting the mesh belt tilted for guidance, the lamp beads roll on the mesh belt and enter the drop pipe 40 for drop. During the rolling process of the lamp beads, the separation effect of the lamp beads and the hair debris is achieved again. In addition, by setting the drop opening 11 above the mesh belt near the fan 50, when the lamp beads drop, most of the hair debris is blown onto the mesh belt on the other side, preventing the lamp beads from rolling on the mesh belt and getting stuck with hair debris. In addition, in the specific implementation, the filter can also be a component with filter holes made of gas flexible material, which can prevent the lamp beads from colliding and breaking, and filter hair debris, and no more examples are given here.

[0029] Specifically, the blanking pipe 40 includes a spiral section 41 and transition sections 42 arranged on both sides of the spiral section 41, one transition section 42 is connected to the middle of the filter element 30, and the other transition section 42 extends from the bottom of the shell 21, and a filter hole is provided at the bottom of the spiral section 41. When the lamp beads are blanked, the lamp beads and the hair debris may not be completely separated, and the lamp beads and the hair debris may enter the blanking pipe 40 together. Therefore, by providing the blanking pipe 40 with a spiral section 41 and providing a filter hole at the bottom of the spiral section 41, the lamp beads and the hair debris can be separated again when they are transported in the spiral section 41. In addition, since the filter hole is only provided at the bottom of the spiral section 41, the hair debris separated by the upper part of the spiral section 41 will not enter the lower part of the spiral section 41 through the filter hole, thereby ensuring the separation effect of the spiral section 41.

[0030] In addition, a vibration component 60 is provided above the mesh material belt away from the fan side, and the vibration rod of the vibration component 60 abuts against the mesh material belt to vibrate the mesh material belt. The vibration component 60 is provided to drive the mesh material belt to shake up and down, thereby further enhancing the separation effect between the lamp beads and the hair debris. In addition, the hair debris is prevented from blocking the filter holes of the mesh material belt and affecting the filtering effect. In addition, since the drop port 11 is provided above the mesh material belt on the side close to the fan 50, there are more hair debris on the mesh material belt on the other side, and then the vibration component 60 is provided on the mesh material belt on the other side, so that the vibration effect here is better, ensuring that the hair debris will not block the filter holes of the mesh material belt.

[0031] Specifically, a heating component is provided in the fan 50 so that the fan 50 continuously blows hot air to the other side of the housing 21. By providing the heating component, the fan continuously blows hot air to the lamp beads, thereby removing the static electricity effect between the lamp beads and the hair, making it easier to separate the lamp beads and the hair. In addition, the hot air can also dehumidify and dry the lamp beads to prevent moisture from penetrating into the lamp beads and damaging the lamp beads, thereby playing a role in extending the service life of the lamp beads in disguise.

[0032] In addition, a discharge port 23 is provided at the bottom of the chip removal bin 20, and the cross-sectional area of ​​the chip removal bin 20 gradually increases from the side close to the drop port 11 to the side of the mesh material belt, and then gradually decreases from the side close to the mesh material belt to the discharge port 23. By setting the cross-sectional area of ​​the chip removal bin 20 to be gradually changed, the guiding effect of the side wall of the shell 21 is achieved, so that the hair debris in the shell 21 is filtered through the filter element 30 and discharged from the discharge port 23 to a preset position along the side wall of the shell 21.

[0033] Specifically, no filter holes are set at the bottom of the spiral section 41 near the discharge port 23. Since the bottom of the chip removal bin 20 is a closed design, the volume inside the shell 21 is smaller as it is closer to the bottom, and the density of the debris distribution is higher as it is closer to the bottom, and both the material delivery pipe 40 and the debris go out through the discharge port 23 at the bottom of the chip removal bin 20. Therefore, in order to prevent debris from entering the material delivery pipe 40 from the filter holes, no filter holes are set at the bottom of the spiral section 41. A small number of spiral sections 41 do not have filter holes, which has little effect on the overall filtering effect of the spiral section 41 and avoids debris from entering the material delivery pipe 40 from the filter holes.

[0034] In addition, the cross section of the bin 10 gradually increases from one side close to the opening 11 to the other side. By setting the two side walls of the bin 10 at an angle, the lamp beads are guided so that the lamp beads move along the inner wall of the bin 10 toward the opening 11.

[0035] Specifically, multiple filter holes are evenly and equidistantly distributed at the bottom of the spiral segment 41, and the area occupied by the multiple filter holes is one-third to one-quarter of the surface area of ​​the spiral segment 41. By limiting the area of ​​the filter holes, the filter holes are distributed in the middle part of the bottom of the spiral segment 41, and the filter holes are not distributed on the side of the spiral segment 41, so that the hair debris can easily enter the spiral segment 41 from the side. Since the filter holes are respectively at the bottom of the spiral segment 41, the hair debris in the chip removal bins 20 on both sides moves downward or drifts left and right under the action of gravity, and thus has no force to move upward, and cannot enter the spiral segment 41 from the filter holes located near the bottom.

[0036] In summary, the lamp bead hair removal and debris dropping device in the above-mentioned embodiment of the utility model is provided with a debris removal bin 20, so that the lamp beads enter the debris removal bin 20 for debris removal after dropping, wherein a fan 50 is provided on one side of the debris removal bin 20, so that in the process of the lamp beads falling down in the debris removal bin 20, under the blowing of the fan 50, the hair on the surface of the lamp beads will be separated from the lamp beads. In addition, a filter element 30 is also provided in the debris removal bin 20, and a dropping pipe 40 is provided in the middle of the filter element 30. After the hair and the lamp beads are separated, they will continue to move downward in the debris removal bin through the filter element 30 and be discharged to the designated position, while the lamp beads are transported to the external material box through the dropping pipe 40 above the filter element 30. In addition, there is a situation where the hair is still attached to the lamp beads after the blowing of the fan 50. The hair will be separated from the lamp beads by the rolling of the lamp beads on the filter element 30 and fall from the filter element 30, thereby performing a secondary separation on the lamp beads to ensure the separation effect between the lamp beads and the hair. In addition, since the chip removal is carried out in the chip removal bin 20, the debris generated by the chip removal is directed to a designated location, thereby avoiding the situation where the debris affects the workshop environment. Therefore, the utility model solves the problem of low efficiency in cleaning debris on the surface of the lamp beads and affecting the workshop environment in the prior art.

[0037] In addition, the utility model also provides a lamp bead blanking system, which includes the above-mentioned lamp bead hair removal and chip blanking device, a conveying track, a pressure plate and a cutting die. The lamp bead hair removal and chip blanking device is located below the conveying track, and the cutting die and the pressing plate are sequentially arranged on the conveying track and are located directly above the lamp bead hair removal and chip blanking device. When in use, the lamp bead holder passes through the cutting die and the pressing plate sequentially to separate the lamp bead from the lamp bead holder and enter the lamp bead hair removal and chip blanking device.
