Then, the colloid is matured by the aging process to show the optical performance of the LED workpiece. With the different requirements of LED optical performance, adding appropriate and appropriate amount 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, it is necessary to prepare enough adhesives with the same proportion of raw material components required for the same batch of boards at one time, in addition to stabilizing the optical performance of the workpiece In addition to performance, the consistency of the same product is also a concern. In the preparation of the adhesive for LED packaging, the manufacturer can often add an appropriate amount of adhesive additives or even powders that can meet the specific performance requirements according to the performance requirements of the demand side. Of course, the user also adjusts the adhesive composition and proportion due to the need for functional adjustment. However, the powder is fully stirred by physical means and dispersed or floated in the gaps between the molecular structure of the adhesive. It does not undergo a chemical cross-linking reaction with the adhesive or is bonded to the molecular structure of the adhesive. As a result, the adhesive is inevitably unevenly distributed due to stratification, suspension, sedimentation, etc. before waiting for the heat curing process in containers such as hoses. Although it may not be intuitively discovered by naked eyes, when the workpiece after heat curing is tested by instruments, the optical performance of the LED board is lost, and the yield and consistency of the finished product are low.

[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 limitation 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 and connected 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, and the first flange 11 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 arranged 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 the hose sleeve 3 is installed 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 outside 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, so that the hose sleeve 3 can be conveniently disassembled and assembled, and the rubber material can be conveniently added to the inside of the hose 1.

[0023] In order to firmly fix the hose sleeve 3 inside the hose 1 and prevent the hose sleeve 3 from rotating inside the hose 1 when supplying glue, in this embodiment, a clamping block 34 is provided on the side wall of the second flange 33, and the clamping block 34 is integrally formed with the second flange 33. The clamping block 34 is clamped on the side wall of the first flange 11. At the same time, in this embodiment, the number of the clamping blocks 34 is two, and the two clamping blocks 34 are respectively clamped on the side walls at both ends of the first flange 11. The side walls of the clamping blocks 34 are arc-shaped structures that match the side walls of the first flange 11 to fix the second flange 33 on the first flange 11 to prevent the hose sleeve 3 from rotating inside the hose 1 when supplying glue, which is conducive to stable glue supply. At the same time, in order to make the hose sleeve 3 more firmly fixed inside the hose 1, the first flange 11 and the second flange 33 can be fixedly connected by bolts. At the same time, in this embodiment, the number of bolts is two, and they are fixedly connected at both ends of the first flange 11 and the second flange 33 respectively.

[0024] In this embodiment, Figure 4As shown, the outer wall of the push rod head 6 is provided with a second sealing ring 62, 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 is slidingly and sealedly connected to the inner wall of the hose 1 through 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 bolts to connect the push rod head 6 with 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 sedimentation can be effectively prevented. Therefore, any blade shape that can effectively prevent the powder sedimentation is within the protection scope of the invention.

[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 the two 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 into the rubber hose 1, take out the rubber hose sleeve 3 from the rubber hose 1, take out the push rod head 6 from the rubber hose 1, and then add the rubber material into the rubber hose 1, when the rubber material is added, push the push rod head 6 into the rubber hose 1, and then install the rubber hose sleeve 3 in the rubber hose 1, and then the addition of the rubber material can be completed;

[0028] When supplying glue, the rubber tube 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 and the connecting tip 5 are rotationally connected, and the push rod 4 and the rubber tube sleeve 3 are threadedly connected, 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 rubber tube 1, and extrude the glue inside the rubber tube 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.
