[0003] Before installing the LED display, the PCB board is cleaned and dried to ensure the surface is clean and flat. Solder paste is printed on the PCB board to prepare for patching. After that, the patching will be carried out. The PCB board with the components is then placed in a reflow oven for soldering. The soldered PCB board is inspected, and the LED lamp beads are installed on the PCB board. After the installation is completed, the lamp beads are soldered and fixed to ensure a firm connection. The cabinet structure is then designed according to the size and installation method of the display. Finally, multiple LED modules are spliced into a complete display screen. The display screen is then tested for electrical performance, including tests of parameters such as voltage, current, and power.

[0004] When glue is poured onto the back of the LED display, the glue pouring machine applies the glue inside the glue box through a glue spraying device. However, if the glue is left inside the glue box for a long time, it will precipitate and delaminate. In addition, the temperature of the glue and the above problems will affect the overall viscosity and adhesion of the glue, which will eventually lead to poor bonding effect of the LED display and affect the quality of the final product.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a connection and sealing device for LED display production, including: a glue filling machine 1 and a glue storage box 2. The glue storage box 2 is arranged directly above the glue filling machine 1, so a protective frame 3 is provided on the vertical surface of the glue storage box 2. The vertical surface where the protective frame 3 and the glue storage box 2 are in contact is made of aluminum. Aluminum has good thermal conductivity and can evenly distribute heat on the plate, so that the resistance wire heats the colloid more evenly, and several U-shaped clamps 4 with the same spacing are provided on the vertical surface inside the protective frame 3. The U-shaped clamp 4 clamps the same resistance wire 5, and one end of the resistance wire 5 passes through the protective frame 3.

[0026] A pair of mutually symmetrical vibration devices 6 are also provided at the vertical surface of the glue storage box 2. The vibration device is a type of vibration motor that converts electrical energy into mechanical energy. It is mainly composed of a motor body, an eccentric block, a protective cover, etc. When the motor is energized, the motor shaft drives the eccentric block to rotate, generating centrifugal force, causing the motor to vibrate. A drive motor 7 is provided on one side of the glue storage box 2. A pair of fixed plates are also provided on the drive motor 7, and the other end of the fixed plate is connected to the vertical surface of the glue storage box 2. The output end of the drive motor 7 passes through the glue storage box 2 and is connected to the rotating rod 8 inside the glue storage box 2. A mounting rod 9 is fixed on the rod body of the rotating rod 8, and several stirring blades 10 are installed on the mounting rod 9. A power supply device 11 is also provided on the upper surface of the glue storage box 2, and an L-shaped connector 12 is provided on the vertical surface of the power supply device 11, and the end of the L-shaped connector 12 away from the power supply device 11 is connected to the resistance wire 5. A rectangular cover 13 is also provided on the cross section of the upper end of the glue storage box 2, and a pair of U-shaped handles are fixedly connected to the upper surface of the rectangular cover 13.

[0027] When in use, first open the rectangular cover 13, then pour the colloid into the glue storage box 2, and then start the drive motor 7, because the output end of the drive motor 7 passes through the glue storage box 2 and is connected to the rotating rod 8 inside the glue storage box 2, and the rod body of the rotating rod 8 passes through and is fixed with a mounting rod 9, and a number of stirring blades 10 are installed on the mounting rod 9. As the drive motor 7 is driven, the stirring blades 10 will rotate and stir the colloid inside the glue storage box 2. Then, start the power supply device 11 so that the power supply device 11 supplies power to the resistance wire 5, and then start the vibration device 6. Because the colloid will generate bubbles during the stirring process, and the heat of the resistance wire 5 changes the viscosity of the colloid, which accelerates the rise and rupture of the bubbles.

[0028] Example 2

[0029] Reference Figure 1 、 3, 5, 6, is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that a pair of rectangular plates 14 are fixedly connected to the vertical surfaces on both sides of the glue filling machine 1, and the rectangular plates 14 are penetrated by threaded rods, and the rod body of the threaded rod is provided with an L-shaped moving block 15 penetrated by it. A circular hole is also provided at the intersection of the L-shaped moving block 15 and the threaded rod, and a thread groove is provided on the arc surface inside the circular hole, and the thread groove is in meshing relationship with the thread on the threaded rod, and a pair of transmission wheels are also provided on the rod body of the threaded rod, and the pair of transmission wheels are connected to the same belt, and one end of one of the threaded rods is connected to the motor.

[0030] The L-shaped moving block 15 is provided with a connecting plate 16 at the vertical surface away from the rectangular plate 14. The vertical surface of the connecting plate 16 is fixedly connected to a round rod 17. A smear cylinder 18 is rotatably connected between a pair of round rods 17. The rod body of the round rod 17 is fixedly connected to the L-shaped plate 19 that is penetrated, and the L-shaped plate 19 is fixedly connected to the glue storage box 2 at the vertical surface away from the connecting plate 16.

[0031] A mounting plate 20 is also provided on the vertical surface of the L-shaped moving block 15, and a hot air blower 21 is also provided on the upper surface of the mounting plate 20. The hot air blower is mainly composed of a motor, a fan, a heating element and a shell. Its working principle is that the motor drives the fan to rotate to generate airflow, and then the airflow is heated by the heating element to form hot air, and finally the hot air is blown out from the air outlet. A support rod 22 is provided on the vertical surface of the mounting plate 20 away from the L-shaped moving block 15, and a rectangular slide groove is also provided at the intersection of the support rod 22 and the glue filling machine 1.

[0032] When in use, first follow the operation in Example 1, then start the motor on the threaded rod, so that the motor drives the threaded rod to rotate. Because the rod bodies of the pair of threaded rods are also provided with transmission wheels, and the pair of transmission wheels are connected to the same belt, when the motor is driven, the pair of threaded rods will also rotate simultaneously. Because the rod bodies of the threaded rods are provided with an L-shaped moving block 15 that is penetrated, a circular hole is also provided at the intersection of the L-shaped moving block 15 and the threaded rod, a thread groove is provided on the arc surface inside the circular hole, and the thread groove is in a meshing relationship with the thread on the threaded rod. As the threaded rod rotates, the L-shaped moving block 15 will move. During the movement, the application barrel 18 will contact the object and generate a rotational force. As the application barrel 18 rotates, it passes through the arc surface of the glue storage box 2 and is contaminated with glue. It is then applied to the object by rotation. After that, the hot blower 21 is started. The hot blower 21 drives the fan to rotate through the motor, generating airflow, which is then heated by the heating element to form hot air. Finally, the hot air is blown out from the air outlet and blows the hot air to the area that has been applied.

[0033] The remaining structures are the same as those of Example 1.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
