Description

Technical Field

[0001] The utility model relates to the technical field of LED packaging systems, in particular to a glue supply structure for delaying powder sedimentation in LED packaging systems. Background Art

[0002] In the LED packaging process, the appropriate adhesive is basically selected based on the functional requirements of the product. Then, according to the condition parameter set in the stage process of the packaging machine function preset, the packaging machine and mold are controlled to heat-seal the adhesive at the preset position of the board to complete the initial thermal curing of the LED board packaging. Then, the colloid is matured by the aging process to show the optical performance of the LED workpiece. As the optical performance requirements of the LED vary, adding appropriate and appropriate amounts of powder to the adhesive and then reasonably physically stirring it so that the powder is fully and evenly dispersed in the adhesive to ensure that the optical performance of the LED workpiece is stable and consistent between batches is a correct, reasonable and effective current method. In packaging practice, preparing enough adhesives with the same ratio of raw material components required for the same batch of boards at one time can not only stabilize the optical performance of the workpiece, but also In addition to performance, consistency across products of the same grade is also a key concern. In the preparation of adhesives for LED packaging, manufacturers can often add additives or even powders to meet specific performance requirements based on the performance needs of the product. Users can also adjust the adhesive components and proportions to accommodate functional needs. However, the powder is physically stirred and dispersed, or floated, within the gaps between the adhesive's molecular structure. It does not undergo a chemical cross-linking reaction with the adhesive or become bonded to the adhesive's molecular structure. This leads to physical variations in the adhesive, such as stratification, suspension, and sedimentation, before it is placed in containers such as hoses for the heat-curing process. While this may not be intuitively apparent to the naked eye, instrumental testing of the heat-cured workpiece reveals a loss of optical performance in the LED board, resulting in low yield and consistency in the finished product.

A glue outlet head 2 connected to the hose 1 is installed at one end of the hose 1. The head of the glue outlet head 2 is tilted to provide a glue outlet, which can facilitate the glue material to be extruded through the glue outlet head 2, thereby facilitating the glue supply. A hose sleeve 3 is installed at the other end of the hose 1. A push rod 4 is threadedly connected to the hose sleeve 3. One end of the push rod 4 is arranged outside the hose 1 and is rotatably installed with a connecting pin 5. The connecting pin 5 can be connected to a glue supply power source when supplying glue to provide power for linear motion for the connecting pin 5. The glue supply power source is one of a cylinder, a hydraulic cylinder or an electric telescopic rod. The other end of the push rod 4 is arranged inside the hose 1 and is equipped with a push rod head 6. The push rod head 6 is slidably arranged inside the hose 1 and is provided with a stirring blade The sheet structure 61, when supplying glue, the glue supply power source can push the connecting tip 5 to move linearly, and the connecting tip 5 can drive the push rod 4 to move linearly. Since the push rod 4 and the connecting tip 5 are rotationally connected, and the push rod 4 and the hose sleeve 3 are threadedly connected, the push rod 4 will rotate while moving linearly. The push rod 4 can drive the push rod head 6 to move linearly and rotate inside the hose 1, and extrude the glue inside the hose 1 through the glue outlet head 2. At the same time, the stirring blade structure 61 on the push rod head 6 can rotate with the push rod head 6 to stir and mix the powder inside the glue material with the glue material to avoid the sedimentation of the powder inside the glue material, thereby avoiding the loss of optical efficiency of the LED board and improving the yield and consistency of the finished LED board.

[0021] In this embodiment, Figure 3As shown, a threaded hole 31 is provided inside the hose sleeve 3, and an external thread is provided on the outer wall of the push rod 4. When the rotation angle of the push rod 4 is constant, the larger the pitch of the external thread, the larger the linear motion stroke of the push rod 4, and the smaller the pitch of the external thread, the smaller the linear motion stroke of the push rod 4. There is no restriction on the pitch of the external thread in this embodiment, and a suitable pitch can be selected according to different rubber materials and powders. The push rod 4 is threadedly connected to the threaded hole 31 of the hose sleeve 3 through the external thread.

[0022] In this embodiment, the hose sleeve 3 is arranged inside the other end of the hose 1, and the outer wall of the hose sleeve 3 is provided with a first sealing ring 32, which is a silicone ring. The outer wall of the hose sleeve 3 is sealed with the inner wall of the other end of the hose 1 through the first sealing ring 32, so that the hose sleeve 3 seals the other end of the hose 1 to prevent the rubber material inside the hose 1 from overflowing. The other end of the hose 1 is provided with a first flange 11, which is an elliptical structure. At the same time, the first flange 11 is integrally formed with the hose 1. One end of the hose sleeve 3 is provided outside the hose 1 and is provided with a second flange 33 matching the first flange 11. The second flange 33 is an elliptical structure, and the second flange 33 is integrally formed with the hose sleeve 3. By arranging the second flange 33 at one end of the hose sleeve 3, it is convenient to hold the hose sleeve 3 when installing the hose sleeve 3 inside the hose 1, so that the hose sleeve 3 can be conveniently installed inside the hose 1. At the same time, the second flange 33 can limit one end of the hose sleeve 3 to the outside of the hose 1 when the hose sleeve 3 is installed inside the hose 1, so as to facilitate the removal of the hose sleeve 3 from the inside of the hose 1, thereby facilitating the disassembly and assembly of the hose sleeve 3, and conveniently adding adhesive material to the inside of the hose 1.

[0023] The second flange 33 is fixed to the cam 32 by the screw thread, and the second flange 33 is fixed to the cam 32 by the screw thread, so that the second flange 33 is fixed to the cam 32.

[0024] In this embodiment, Figure 4As shown, a second sealing ring 62 is provided on the outer wall of the push rod head 6, and the second sealing ring 62 is a silicone ring. The outer wall of the push rod head 6 is slidingly and sealedly connected to the inner wall of the hose 1 through the second sealing ring 62. The outer wall of the push rod head 6 and the inner wall of the hose 1 are slidingly and sealed by the second sealing ring 62, which can help the push rod head 6 to extrude the rubber material inside the hose 1. It should be noted that a mounting hole is provided in the center of the push rod head 6, and one end of the push rod 4 located inside the hose 1 is fixed inside the mounting hole by a bolt to connect the push rod head 6 to the push rod.

[0025] In this embodiment, the stirring blade structure 61 includes a plurality of blades centered on the central axis of the push rod head 6 and evenly arranged on the side of the push rod head 6 away from the push rod 4. At the same time, the blades and the push rod head 6 are integrally formed. It should be noted that the shape of the blades can be adjusted according to the viscosity of the glue and the properties and quality of the added powder. By adjusting the appropriate blade shape, the powder can be effectively prevented from settling. Therefore, any blade shape that can effectively prevent the powder from settling is within the protection scope of the utility model.

[0026] In this embodiment, Figure 5 As shown, the connecting tip 5 includes a tip rod 51, a mounting sleeve 52 is vertically installed in the middle of the tip rod 51, a bearing 53 is installed inside the mounting sleeve 52, the bearing 52 is a ball bearing, and there are two bearings 52, which are respectively installed at both ends inside the mounting sleeve 52, and the two bearings 52 are separated by a gasket. A rotating shaft 54 ​​is rotatably installed inside the bearing 53, and one end of the rotating shaft 54 ​​is connected to the end of the push rod 4 located outside the hose 1. The connecting tip 5 using the above design can be rotatably connected to the end of the push rod 4 located outside the hose 1. It should be noted that the tip rod 51 and the mounting sleeve 52 are connected by bolts.

[0027] Specific principle: When adding rubber material to the inside of the hose 1, remove the hose sleeve 3 from the inside of the hose 1. After the hose sleeve 3 is removed from the inside of the hose 1, remove the push rod head 6 from the inside of the hose 1, and then add the rubber material to the inside of the hose 1. When the rubber material is added, push the push rod head 6 into the inside of the hose 1, and then install the hose sleeve 3 inside the hose 1 to complete the addition of the rubber material.

[0028] When supplying glue, the hose 1 is installed on the packaging machine, and the connecting tip 5 is connected to the glue supply power source. The connecting tip 5 is pushed by the glue supply power source to move linearly, and the connecting tip 5 can drive the push rod 4 to move linearly. Since the push rod 4 is rotationally connected to the connecting tip 5, and the push rod 4 is threadedly connected to the hose sleeve 3, the push rod will rotate while moving linearly. The push rod 4 can drive the push rod head 6 to move linearly and rotate inside the hose 1, and extrude the glue inside the hose 1 through the glue outlet head 2. At the same time, the stirring blade structure 61 on the push rod head 6 can rotate with the push rod head 6 to stir and mix the powder inside the glue material with the glue material, thereby avoiding the sedimentation of the powder inside the glue material, thereby avoiding the loss of optical efficiency of the LED board and improving the yield and consistency of the finished LED board.
