[0024] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As shown in the Figure 1 to Figure 4 accompanying drawings:

[0026] Embodiment 1: The present utility model provides a packaging mold for increasing the light output efficiency of a display light source, including a main body 1, including a base 101, mold frames 102 arranged on both sides of the top of the base 101, a mold core 103 arranged between the mold frames 102, and side frames 104 arranged at both ends of the mold frames 102; a disassembly and assembly mechanism 2, including a movable member arranged between the mold frame 102 and the side frame 104, and a connecting member arranged on the side frame 104; and a buffer mechanism 3, including a rotating member 308 arranged at the bottom of the mold frame 102, two swing arms 307 arranged on the rotating member 308, a buffer member arranged between the swing arm 307 and the base 101, a toothed shaft 309 arranged on the swing arm 307, and a detecting member arranged on the base 101.

[0027] Specifically, the movable member includes sliding grooves 204 arranged on the surfaces of both ends of the mold frame 102, and sliders 205 slidably arranged in the sliding grooves 204.

[0028] Furthermore, a connecting rod 201 is installed between the side frames 104, and push-pull rods 202 are installed at both ends of the mold core 103.

[0029] Even further, the connecting member includes a fixing bolt 203 threadedly arranged on the side frame 104, and the fixing bolt 203 penetrates through the slider 205.

[0030] As can be seen from the above, when packaging, it is only necessary to first stretch the release film onto the device so that it covers the upper surfaces of the mold frame 102, the mold core 103 and the side frame 104, and then inject glue onto the mold core 103, with the LED panel on top, in an inverted position, and position it through the Mark point, place each pixel light source in the groove on the upper surface of the mold core 103, and after ensuring that the positions are completely overlapped, apply pressure on the LED panel to press it down onto the mold core 103 to ensure a tight fit. After the colloid is cured, it is demolded through the release film, and the packaging work is completed after the excess colloid on the edge is cut off by a CNC milling cutter. The mold core 103 is packaged and formed once, and the arc-shaped groove on the upper surface of the mold core 103 can make the shape of the package hemispherical. In this way, when the light is emitted from the packaging material to the air, it is almost vertical to the interface, and the incident angle will be less than the critical angle, thereby reducing the probability of total reflection and improving the light output efficiency of the independent pixel light source. In addition, the fixing bolt 203 can be rotated as needed to fix it. The threaded connection relationship between the bolt 203 and the side frame 104 allows the fixing bolt 203 to move back and forth on the side frame 104, so that the fixing bolt 203 is separated from the mold frame 102, thereby releasing the limited state of the side frame 104, and the connecting rod 201 can be held and lifted upward to push the two side frames 104 to move upward synchronously. The slide groove 204 will limit the range of movement of the side frame 104 through the slider 205 until the side frame 104 moves to the top of the mold core 103, and then the fixing bolt 203 is rotated in the opposite direction to make it contact with the mold frame 102, so as to limit the position of the side frame 104 through the contact friction force. At this time, the mold core 103 can be removed from the device by holding the push-pull rod 202 and pushing and pulling, so that the personnel can replace the mold core 103 conveniently. At the same time, the fixing bolt 203 can be rotated as needed to separate it from the mold frame 104 and then continue to rotate until the fixing bolt 203 is separated from the slider 205, so that the personnel can remove the side frame 104 from the device for local replacement and maintenance.

[0031] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the buffer member includes a movable block 305 arranged between the rocker arms 307, a limiting groove 306 arranged on the top surface of the base 101, and a spring 304 arranged between the movable block 305 and the limiting groove 306.

[0032] Specifically, the detection component includes a pressure sensor 301 disposed on the top of the base 101 , a display screen 302 disposed at one end of the base 101 , and an indicator light 303 disposed at one end of the base 101 .

[0033] As can be seen from the above, when the LED panel is buckled on the die core 103 and pressure is applied downward, it will drive the die core 103 and the die frame 102 to move downward synchronously, so as to drive the movable block 305 to move back and forth in the limit groove 306 through the rocker arm 307. Then, the impact force is absorbed and buffered by a plurality of springs 304. The rocker arm 307 will swing through the movable part 308, and the meshing of the two gear shafts 309 will limit the swing angles of the two rocker arms 307 to keep their swing angles always the same. The die core 103 will always move up and down to avoid shaking caused by moving back and forth, effectively avoiding the situation that the positions of the LED panel and the die core 103 are misaligned, improving the buffering effect of the device, avoiding the situation that the structure is damaged due to excessive impact force, prolonging the service life of the device. When the die core 103 contacts the pressure sensor 301 downward, the pressure sensor 301 will detect the pressure applied downward by the LED panel, avoiding the situation that the structure is damaged due to excessive pressure or the situation that the LED panel and the die core 103 are not tightly pressed together due to too small pressure, which affects the encapsulation effect, improving the encapsulation effect and encapsulation efficiency, and facilitating the use of personnel.
