[0035] See Figure 1 and Figure 5The embodiment provides a dispensing system for a TOP LED lamp bead 5, which comprises a conveying device 1, a dispensing device 2, a scraping device 3 and a homogenizing net 4. The conveying device 1 is used for conveying a packaging module to be dispensed and a packaging module after dispensing. The packaging module to be dispensed comprises a plurality of TOP LED lamp beads 5 to be dispensed, and the top of the TOP LED lamp bead 5 to be dispensed is formed with a bowl cup 51 to be dispensed. The dispensing device 2 and the scraping device 3 are arranged above the conveying device 1, and the scraping device 3 is arranged on one side of the dispensing device 2. The homogenizing net 4 is arranged between the dispensing device 2 and the conveying device 1. The dispensing device 2 comprises a glue cylinder 21, a fixing member 22 and a dispensing valve body 23. The fixing member 22 is in communication with the glue cylinder 21 and the dispensing valve body 23, so as to dispense the packaging glue in the glue cylinder 21 through the dispensing valve body 23. The homogenizing net 4 comprises a plurality of mesh holes 41. The packaging glue dispensed through the dispensing valve body 23 is dispensed into the bowl cup 51 to be dispensed through the mesh holes 41, and is scraped by the scraping device 3.

[0036] Based on the above-mentioned embodiment, after the packaging module to be dispensed is conveyed to the lower side of the dispensing device 2 by the conveying device 1, the dispensing valve body 23 dispenses, the packaging glue dispensed is homogenized through the mesh holes 41 and then enters the bowl cup 51 to be dispensed, and then is scraped by the scraping device 3. During the scraping process, part of the packaging glue remaining on the homogenizing net 4 can fill the bowl cup 51 to be dispensed, so as to improve the dispensing uniformity, and further optimize the brightness uniformity, the light-emitting angle uniformity and the light color uniformity of the TOP LED lamp bead.

[0037] Specifically, referring to Figure 2 , the mesh holes 41 on the homogenizing net 4 are arranged one by one corresponding to the TOP LED lamp beads 5 to be dispensed on the packaging module, so that the dispensing can be directly dispensed into the bowl cup 51 to be dispensed through the mesh holes 41. Specifically, the cross-sectional shape of the mesh hole 41 can be circular, elliptical, square, chamfered square, pentagonal or hexagonal, but is not limited thereto. Preferably, in an embodiment, the cross-sectional shape of the mesh hole 41 is square, circular or elliptical, which is more convenient for the packaging glue dispensed by the dispensing valve body 23 to enter the bowl cup to be dispensed. More preferably, the cross-section of the mesh hole 41 is circular, which not only makes it more convenient for the packaging glue to enter the bowl cup to be dispensed, but also improves the flow uniformity of the packaging glue in the bowl cup 51 to be dispensed, further improving the dispensing uniformity.

[0038] Further, in order to optimize the dispensing uniformity, the width of the mesh hole 41 should be slightly larger than the width of the bowl cup 51 to be dispensed. The width of the mesh hole 41 refers to the maximum characteristic width thereof, for example, when the mesh hole 41 is circular, the width is the diameter thereof; when the mesh hole 41 is elliptical, the width is the length of the major axis thereof, and when the mesh hole 41 is quadrilateral, the width is the length of the longest side thereof. Correspondingly, the width of the dispensing bowl cup refers to the maximum characteristic dimension of the cross-sectional shape of the top thereof.

[0039] Specifically, referring toFigure 3 In one embodiment, the conveying device 1 comprises a conveying table 11 and a conveying belt 12 arranged in the conveying table 11, the top surface of the conveying belt 12 is lower than the top surface of the conveying table 11, so as to fix the encapsulation module to be glued by the conveying table 11, prevent the encapsulation module from moving during the scraping by the scraping device 3, and reduce the uniformity of the gluing.

[0040] More preferably, in order to fix the encapsulation module after gluing, the homogenizing net 4 is fixed with the conveying device 1, and then the encapsulation module before and after gluing is pressed and fixed by the homogenizing net 4. More specifically, in one embodiment, the homogenizing net 4 is fixed on the top surface of the conveying table 11, and the gluing system further comprises a jacking device 6, which can press the encapsulation module to the lower side of the homogenizing net 4, so as to fix the encapsulation module to be glued.

[0041] Specifically, referring to Figure 1 In another embodiment, the gluing system further comprises a fixing plate 7, a plurality of strip-shaped holes are arranged on the fixing plate 7, which are used to limit the TOP LED lamp beads 5 on the encapsulation module, so as to further fix the encapsulation module. It should be noted that, since the homogenizing net 4 is arranged above the encapsulation module, when the encapsulation module is pressed on the homogenizing net 4 in the vertical direction by the jacking device 6, there is still a possibility that the encapsulation module will move horizontally during the horizontal scraping by the scraping device 3. Therefore, the fixing plate 7 is introduced in this embodiment, and the strip-shaped holes arranged on the fixing plate 7 can further position the TOP LED lamp beads 5 in the horizontal direction, so as to further improve the uniformity of the gluing.

[0042] Based on this embodiment, the fixing plate 7 and the homogenizing net 4 are both fixed on the conveying device 1, and the homogenizing net 4 is fixed above the fixing plate 7. More specifically, the fixing plate 7 and the homogenizing net 4 are both fixed on the top surface of the conveying table 11, which can simplify the structure.

[0043] More specifically, a plurality of strip-shaped holes are arranged on the fixing plate 7 in the length direction of the fixing plate 7, and the encapsulation module to be glued comprises a material falling support and a plurality of rows of TOP LED lamp beads fixed on the material falling support; each row of TOP LED lamp beads 5 to be glued of the encapsulation module to be glued extends out of the strip-shaped hole.

[0044] More specifically, a predetermined distance is arranged between the fixing plate 7 and the homogenizing net 4, so that the homogenizing net 4 can press the encapsulation module to be glued. It should be noted that the gluing bowl cup 51 of the TOP LED lamp bead 5 to be glued on the material falling support has a certain height, and by arranging the distance between the fixing plate 7 and the homogenizing net 4, the homogenizing net 4 can just press on the top surface of the gluing bowl cup 51, so as to further optimize the uniformity of the gluing.

[0045] Specifically, in one embodiment, the scraping device 3 can be a doctor blade, but is not limited thereto. More preferably, in one embodiment, the doctor blade has a wedge-shaped bottom, which can form a storage space for temporarily storing the encapsulation glue. This avoids the accumulation of too much encapsulation glue on the homogenizing net 4.

[0046] Specifically, the scraping device 3 can be an independently arranged and driven mechanism. Preferably, referring to Figure 4 In one embodiment, the scraping device 3 is fixed on the fixing member 22, and the scraping device 3 is arranged outside the glue dispensing valve body 23. That is, the glue dispensing valve body 23 and the scraping device 3 are synchronously driven, which can simplify the structure of the glue dispensing system.

[0047] In summary, the glue dispensing system for the TOP LED lamp bead 5 includes the transmission device 1, the glue dispensing device 2, the scraping device 3 and the homogenizing net 4. The homogenizing net 4 is arranged between the glue dispensing device 2 and the encapsulation module to be dispensed, and includes a plurality of mesh holes 41. The encapsulation glue is dispensed by the glue dispensing device 2 and then enters the glue dispensing bowl cup through the mesh holes 41. Based on the glue dispensing system, the dispensing amount can be made consistent, the dispensing uniformity is improved, and then the brightness uniformity, the light-emitting angle uniformity and the light color uniformity of the TOP LED lamp bead 5 are optimized.
