[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The existing glue dispensing equipment has the problem that the glue head is easily adhered to the glue.

[0022] To this end, the present invention provides a dispensing device for lamp bead packaging, see Figure 1-Figure 3As shown, it includes a driving device 1, on which a mounting frame 2 is arranged, and also includes a conveying device 8 with a conveyor belt 3 structure, the conveyor belt 3 passes through the inside of the driving device 1, and a lamp bead board 4 is conveyed on the conveyor belt 3, on which a plurality of lamp beads 11 are arranged in a matrix, a plurality of glue pumps 7 are slidably connected to the mounting frame 2, and the glue pump 7 is slidably connected to a support frame 6 on the side close to the conveyor belt 3, and a glue gun 5 for gluing the lamp beads 11 on the lamp bead board 4 is arranged on the support frame 6, and a driving device for driving the glue gun 5, the support frame 6 and the glue pump 7 to move longitudinally and transversely, frontward, rearward, leftward and rightward respectively is arranged in the driving device 1, and a fixing plate 9 for aligning and fixing the lamp bead board 4 is arranged on the mounting frame 2, and a plurality of fixing grooves 10 are opened on the fixing plate 9, and the fixing grooves 10 correspond to the number of columns of the lamp beads 11 arranged in a matrix on the lamp bead board 4.

[0023] Specifically, Figure 2-Figure 6 As shown, the glue pump 7 is also provided with a cleaning component that moves laterally with the glue pump 7, and is used to clean the glue outlet of the glue dispensing gun 5. The cleaning component includes a lower clamping plate 13 fixed on the glue pump 7, and the lower clamping plate 13 is located directly below the glue outlet of the glue dispensing gun 5 at the initial position. An upper clamping plate 14 is slidably provided on the lower clamping plate 13, and a plurality of teeth are provided on the lower clamping plate 13 and the upper clamping plate 14, and a notch 34 is formed between the plurality of teeth; in the initial state, the notches 34 of the lower clamping plate 13 and the upper clamping plate 14 are aligned to form a through opening, and the glue dispensing gun 5 The glue outlet head is located just above the through opening; mounting plates 12 are symmetrically arranged on both sides of the fixing plate 9, one of the mounting plates 12 is provided with a corrugated plate 19, one side of the upper clamping plate 14 is in contact with the corrugated plate 19, and the other side of the upper clamping plate 14 is provided with an elastic telescopic component, which is slidably connected to the other mounting plate 12; after the glue is dispensed on a horizontal row of lamp beads 11, the glue pump 7 drives the lower clamping plate 13 to move to the next row, and the upper clamping plate 14 reciprocates horizontally in a wave-like manner on the corrugated plate 19, which is used to clean the glue outlet head of the glue dispensing gun 5.

[0024] It can be seen that after the glue dispensing gun 5 is retracted after dispensing the glue, it moves to the next row under the drive of the glue pump 7, which will drive the upper clamping plate 14 to move on the wave plate 19. Due to its wave-like structure and the elastic force of the elastic contraction component, the upper clamping plate 14 will scrape off the glue that may be stuck to the glue outlet head of the glue dispensing gun 5 every time the glue pump 7 moves forward, and then reset.

[0025] Among them, Figure 3-Figure 4 As shown, connecting rods 31 are arranged on both sides of the lower clamping plate 13, and the lower clamping plate 13 is fixedly connected to the glue pump 7 through the connecting rods 31. A receiving groove 15 is detachably connected to the side of the lower clamping plate 13 away from the teeth, which is used to store the glue adhered to the glue discharge head after cleaning. The receiving groove 15 is provided with a plurality of collecting ports 28 corresponding to the center positions of the notches 34. Secondly, for the lower clamping plate 13, see Fig.12As shown, a second guide groove 27 is provided between two teeth on the lower clamping plate 13, and the second guide groove 27 is connected to the collecting port 28. The second guide groove 27 is inclined, and the end away from the collecting port 28 is higher, so that the inflowing glue can smoothly flow into the collecting port 28 and then enter the receiving groove 15.

[0026] Further, such as Figure 3-Figure 4 and Figure Figure 11-Figure 12 As shown, the teeth of the upper clamping plate 14 match the teeth of the lower clamping plate 13, and the side of the teeth of the upper clamping plate 14 away from the corrugated plate 19 is a sharp structure, and a first guide groove 26 is provided through the upper clamping plate 14 at the position of the teeth, and the first guide groove 26 matches the second guide groove 27, and when the teeth of the upper clamping plate 14 are located at the notch 34 of the lower clamping plate 13, the first guide groove 26 and the second guide groove 27 are connected; It is worth adding that the length of the first guide groove 26 exceeds the second guide groove 27, the exceeding part is located on the teeth of the upper clamping plate 14, and the bottom end of the part of the first guide groove 26 exceeding the second guide groove 27 is inclined to facilitate the flow of fallen glue into the second guide groove 27; and the end of the first guide groove 26 located on the teeth of the upper clamping plate 14 is adapted to the sharp structure of the teeth of the upper clamping plate 14, and when the glue discharge head of the glue dispensing gun 5 returns to its initial position, its bottom end is flush with an edge of the first guide groove 26 away from the sharp side; secondly, the glue discharge head of the glue dispensing gun 5 is smaller than the notch 34, and is located on the side of the corrugated plate 19 directly above the notch 34, that is, it is not located directly above the middle of the notch 34, but has a certain offset, so that when the first guide groove 26 is connected to the second guide groove 27, The part of the first guide groove 26 located on the teeth of the upper clamp plate 14 passes over the glue discharge head. It can be concluded that when the glue discharge head of the glue dispensing gun 5 moves to the initial position and advances to the next row driven by the glue pump 7, the higher edge of the first guide groove 26 on the upper clamp plate 14 will pass over the bottom of the glue discharge head and scrape the adhered glue into the part of the first guide groove 26 located on the teeth, and then flow into the second guide groove 27 and then into the receiving groove 15. After the work is completed, the receiving groove 15 can be disassembled and cleaned and recycled. It should be noted here that the cleaning component can only clean most of the adhered glue, and it is inevitable that some of it will enter the lower clamp plate 13 and the upper clamp plate 14. Therefore, the lower fixing plate 9 not only plays the role of fixing the lamp bead plate 4, but also can reduce the risk of some glue falling on the lamp bead 11.

[0027] Therefore, it is necessary to set the teeth of the upper clamping plate 14 to be an inclined structure, that is, it is necessary to set the part away from the corrugated plate 19 to be a sharp structure. First, some glue wire drawing can be cut off. Then, since the first guide groove 26 also becomes an inclined structure, the edge of the higher end of the first guide groove 26 can be used as a scraper to scrape the glue head. Second, it is convenient for the glue to be scraped into the first guide groove 26. The lower end of the inclined structure can provide a higher activity space for the glue to stick, preventing some glue from sticking too long, that is, If there is a wire drawing, it will first be cut off by the sharp teeth of the upper clamping plate 14 and the teeth of the lower clamping plate 13, and then the larger glue in the shape of beads or strips will be injected into the part of the first guide groove 26 located on the teeth, and then gradually pass through the glue head on the higher edge of the first guide groove 26 for scraping, and then the glue falls into the first guide groove 26, that is, the glue head is located on one side of the first guide groove 26 at this time; then the glue pump 7 continues to move forward, and the upper clamping plate 14 is reset. The specific reciprocating operation of the upper clamping plate 14 is described below: The distance that the glue gun 5 moves each time along the conveying direction, the interval between adjacent notches 34 and the interval between adjacent first guide grooves 26 are adapted to the interval between the lamp beads 11 arranged in adjacent rows on the lamp bead plate 4 .

[0028] See also Figure 4 , Figure 6 , Figure 7 and Figure 10-12 As shown, the two ends of the upper clamping plate 14 are respectively fixedly connected with the second push rod 20 and the first push rod 18, the second push rod 20 fits with the wave plate 19, the convex parts of two adjacent waves of the wave plate 19 are adapted to the distance between the adjacent horizontal rows of lamp beads 11 on the lamp bead plate 4, and the distance of the lateral movement of the second push rod 20 lifted by the wave plate 19 is adapted to the distance between the two adjacent notches 34; and the upper clamping plate 14 mentioned above works under the cooperation of the elastic contraction component, wherein the elastic contraction component includes a slide rail 16, and the slide rail 16 is fixedly connected to the wave plate 19 away from the wave plate 19 On the other mounting plate 12, a contraction box 17 is slidably connected to the slide rail 16, a push plate 32 is slidably connected in the contraction box 17, a spring 33 is fixed in the contraction box 17, one end of the spring 33 is fixedly connected to the push plate 32, and the other end is fixedly connected to the contraction box 17, the push plate 32 is fixedly connected to the first push rod 18, the thrust of the spring 33 can cause the upper clamping plate 14 to reset, and the length of the contraction box 17 is adapted to the distance between the two adjacent notches 34, that is, the distance that the push plate 32 can move in the contraction box 17 is greater than the distance between the two adjacent notches 34.

[0029] It can be seen from this that the second push rod 20 slides on the corrugated plate 19, and when it slides to the convex part, the upper splint 14 is pushed to the other side due to its structure, and then the first push rod 18 at the other end of the upper splint 14 will be squeezed into the contraction box 17, and then the lower splint 13 moves forward again, and the second push rod 20 on the upper splint 14 is inserted into the concave part, and the upper splint 14 is reset by the elastic force of the spring 33 in the contraction box 17, completing the cleaning of the glue head; it is necessary to sort out the working process in a brief way here, that is, dispensing - the dispensing gun 5 rises - the dispensing gun 5 moves to the next row - the second push rod 20 moves from the concave part to the convex part - the glue head cleaning is completed - the dispensing gun 5 moves to the next row - at this time the second push rod 20 is located in the concave part again.

[0030] The second object of the present invention is to provide an LED lamp bead 11, which includes a lamp part, a wire part, a PCB board and a packaging layer, and the lamp part, the wire part, the PCB board and the packaging layer are arranged in sequence from bottom to top, and the packaging layer is packaged by the above-mentioned dispensing equipment for lamp bead packaging.

[0031] The third object of the present invention is to provide a working method for the above-mentioned glue dispensing device for lamp bead packaging, comprising the following method steps: S1. When the lamp bead board 4 is transferred to the bottom of the fixing plate 9, the lamp bead board 4 is fixed under the fixing plate 9, and each row of lamp beads 11 corresponds to the fixing groove 10; S2, the driving device drives the glue pump 7 and the glue gun 5 to move forward, glue the first row of a certain column of lamp beads 11, and then move forward along the corrugated plate 19 to glue the second row. At this time, the upper clamping plate 14 will slide on the corrugated plate 19 through the second push rod 20, and when passing the convex part of the corrugated plate 19, it will push the upper clamping plate 14 to move toward the shrink box 17; S3, during the movement of the upper clamping plate 14, a higher edge of the inclined surface structure of the first guide groove 26 will pass over the glue outlet of the glue dispensing gun 5 and scrape off the glue at the glue outlet; S4. The scraped glue will fall into the second guide groove 27 through the first guide groove 26, and finally flow into the receiving groove 15 for temporary storage.

[0032] In summary, the problem that the glue head of the existing glue dispensing equipment is easily adhered to glue is effectively solved.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention.
