Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] As Figure 1 , Figure 2 , Figure 6 shown, the present invention provides a technical solution: an efficient and reliable LED lamp bead curing device, including a frustum 1 and an overheat prevention mechanism 5;

[0034] A transmission device 2 is fixedly connected to the top of the frustum 1. A protective shell 3 is fixedly connected to a position near the side of the top of the transmission device 2. An opening and closing plate 4 is rotatably connected to the surface of the protective shell 3;

[0035] The overheat prevention mechanism 5 is arranged at the middle position of the inner side surface of the protective shell 3. The LED lamp beads are irradiated and cured by ultraviolet rays. The transmission device 2 conveys the LED lamp bead board into the interior of the protective shell 3. The overheat prevention mechanism 5 is driven to move downward close to the LED lamp bead board for light curing. The overheat prevention mechanism 5 uses gas flow to cool the ultraviolet lamp;

[0036] It further includes a uniform mechanism 6. The uniform mechanism 6 is arranged on the side of the overheat prevention mechanism 5 away from the ultraviolet lamp. The air flow cools the overheat prevention mechanism 5. After the air flow is heated, it is introduced into the uniform mechanism 6. The uniform mechanism 6 is driven by the overheat prevention mechanism 5 to move downward to apply glue to the LED lamp bead board; including a colloid shell 65. An efficiency enhancement assembly 64 is fixedly connected to the top of the colloid shell 65. An extrusion assembly 66 is fixedly connected to the bottom of the inner side surface of the colloid shell 65. The extrusion assembly 66 moves downward to extrude the colloid onto the LED lamp bead board for glue application;

[0037] A mechanism wall 61 is fixedly connected to the position above the surface of the efficiency enhancement assembly 64. A filter plate 62 is fixedly connected to the inner side surface of the mechanism wall 61. An electric cylinder 63 is fixedly connected to the bottom of the mechanism wall 61.

[0038] During use, the transmission device 2 drives the LED board into the interior of the protective shell 3. The transmission device 2 stops moving, and the overheat prevention mechanism 5 drives the mechanism wall 61 and the ultraviolet lamp downward. The mechanism wall 61 is fixedly connected to the colloid shell 65, so that the colloid shell 65 is close to the LED board. A plurality of extrusion components 66 are arranged at the bottom of the colloid shell 65. The piston rod at the output end of the electric cylinder 63 moves downward to stir and extrude the colloid inside the colloid shell 65. The colloid is extruded from the extrusion components 66, thereby simultaneously dispensing glue on a plurality of lamp beads on the LED board. The ultraviolet lamp is also driven downward to cure the LED board after dispensing glue, solving the problem that when encapsulating a plurality of lamp beads on the LED board, dispensing glue on each lamp bead one by one will cause uneven curing of the lamp beads.

[0039] As Figure 6 、 Figure 7 、 Figure 8 As shown in [figures], the efficiency enhancement component 64 includes a fixing plate 641. The bottom of the fixing plate 641 is fixedly connected to the top of the colloid shell 65. An air flow pipe 642 is fixedly connected to the surface of the fixing plate 641. The upper position on the surface of the air flow pipe 642 is fixedly connected to the inner side surface of the mechanism wall 61. A pressure valve 643 is fixedly connected to the top of the fixing plate 641. The output end of the electric cylinder 63 extends into the interior of the colloid shell 65. The bottom end of the output end of the electric cylinder 63 is fixedly connected to a pressing plate 644. The extrusion component 66 includes a fixing ring 661. The surface of the fixing ring 661 is fixedly connected to the bottom of the colloid shell 65. A plastic conical wall 662 is fixedly connected to the bottom of the fixing ring 661. Extrusion holes 663 are formed on the surface of the plastic conical wall 662. A pressing block 664 is fixedly connected to the position on the bottom of the pressing plate 644 close to the plastic conical wall 662. The bottom of the pressing block 664 communicates with the upper position of the pressing plate 644.

[0040] During use, the interior of the colloid shell 65 is filled with glue for dispensing. The top of the pressing block 664 communicates with the colloid. The air flow pipe 642 fixedly connects the mechanism wall 61 and the colloid shell 65. When the mechanism wall 61 is driven downward, the plastic conical wall 662 approaches the LED board. The top of the plastic conical wall 662 is fixed through the fixing ring 661. The extrusion holes 663 block the colloid with high viscosity. When the pressing plate 644 is driven downward, the pressing block 664 presses the inner side surface of the plastic conical wall 662, causing the plastic conical wall 662 to undergo plastic deformation, and the extrusion holes 663 are pushed open. The colloid falls to the positions of the lamp beads on the LED board. The device is provided with a plurality of plastic conical walls 662, and the glue dropping is driven by the same pressing plate 644, so that a plurality of lamp beads on the LED board are evenly dispensed with glue.

[0041] As Figure 3 、 Figure 6As shown, the overheat prevention mechanism 5 includes a fixed wall 51, the surface of the fixed wall 51 is fixedly connected to the middle position of the inner side of the protective shell 3, a motor 52 is fixedly connected to the top of the fixed wall 51, a lead screw 53 is fixedly connected to the output shaft of the motor 52, a lifting component 54 is threadedly connected to the surface of the lead screw 53, a bent pipe 55 is fixedly connected to the upper position of the surface of the lifting component 54, a guiding component 56 is fixedly connected to one end of the bent pipe 55, the other end of the bent pipe 55 is fixedly connected to the top of the uniform mechanism 6, an efficiency enhancement component 64 is fixedly connected to the top of the colloid shell 65, an extrusion component 66 is fixedly connected to the bottom of the inner side of the colloid shell 65, and the extrusion component 66 moves downward to extrude the colloid onto the LED lamp bead board for dispensing glue; an institutional wall 61 is fixedly connected to the upper position of the surface of the efficiency enhancement component 64, a filter plate 62 is fixedly connected to the inner side of the institutional wall 61, and an electric cylinder 63 is fixedly connected to the bottom of the institutional wall 61.

[0042] During use, the motor 52 drives the lead screw 53 to rotate, the lifting component 54 is driven to move downward, the bent pipe 55 drives the institutional wall 61 and the guiding component 56 to move downward simultaneously, the lifting component 54 blocks the position between the colloid shell 65 and the guiding component 56 to prevent the ultraviolet light from curing the colloid inside the colloid shell 65, the airflow is driven to cool the guiding component 56, the bent pipe 55 passes the heated gas into the interior of the institutional wall 61, the filter plate 62 removes impurities from the heated gas and then passes it into the colloid shell 65, the colloid inside the colloid shell 65 transfers heat with the gas, and the colloid inside the colloid shell 65 is heated to increase its fluidity, solving the problem that the ultraviolet curing lamp is prone to extinguish due to overheating.

The guiding component 56 includes a component wall 561, a blower 564 is fixedly connected to the top of the component wall 561, the output end of the blower 564 is fixedly connected to the end face of the bent pipe 55, an opening 562 is opened at the side position of the surface of the component wall 561, and an ultraviolet lamp 563 is fixedly connected to the bottom of the inner side of the component wall 561. The input end of the blower 564 is communicated with the interior of the component wall 561.

[0044] During use, in the prior art, the dispensing and curing of the LED lamp bead board are carried out by separate machines, which easily leads to problems such as impurities on the surface of the LED lamp bead board and uneven curing of the lamp beads. The lead screw 53 drives the lifting block 541 to move downward through the screw thread lift force, and the baffle plate 543 and the elbow pipe 55 are driven to move downward. The connecting table 544 supports the elbow pipe 55, and the ultraviolet lamp 563 approaches the LED lamp bead board after dispensing, so that the curing efficiency of the ultraviolet lamp 563 is effectively improved. At the same time, the distance between the LED lamp bead board and the extrusion assembly 66 is reduced, and the colloid inside the colloid shell 65 is extruded into the LED lamp bead board. The LED lamp bead board is directly cured after dispensing, which can effectively improve the curing efficiency between the lamp beads of the LED lamp bead board.

[0045] As Figure 5 , Figure 7 shown, a blower 564 is fixedly connected to the top of the component wall 561. The output end of the blower 564 is fixedly connected to the end face of the elbow pipe 55. An opening 562 is formed in the side position of the surface of the component wall 561.

[0046] During use, an opening 562 is formed in the side position of the surface of the component wall 561. The ultraviolet lamp 563 releases ultraviolet rays to cure the colloid of the LED lamp bead board. The blower 564 drives the gas to flow at the position of the opening 562. After the gas is heated, it is introduced into the inside of the elbow pipe 55. The elbow pipe 55 introduces the heated gas into the inside of the mechanism wall 61.
