[0026] In order to ensure the stability of the installation of the eight electric push rods 1 7 and the electric push rod 2 17, two fixing plates are fixedly installed on the bottom inner wall of the four box bodies 2 4, and a U-shaped clamp 1 is fixedly installed on one side of the eight fixing plates.

[0030] The working principle of the light source board pressing device of the LED bulb provided by the utility model is as follows:

[0031] When the light source board needs to be pressed together, start the motor 2, which will drive the four boxes 2 4 to rotate clockwise through the connecting block 3. During the rotation of the four boxes 2 4, they will automatically stop moving after rotating to the position of the next probe hole 5, ensuring that the four boxes 2 4 are always aligned with the corresponding probe holes 5, and the constituent materials of the light source board are neatly placed on the top of the box 2 4 through the three exposed probe holes 5, so that the constituent materials are located between the corresponding four baffles 15, until the light source board materials are placed on the top of the four boxes 2 4, the action of placing the light source board materials can be stopped.

[0032] The pressing plate 18 is pressed against the bottom surface of the light source board, and the pressing plate 18 is pressed against the bottom surface of the light source board, so that the light source board material can be formed in one piece. During the pressing of the light source board by the pressing plate 18, the motor 2 stops rotating. After the pressing of the light source board is completed, the pressing plate 18 is driven by the pressing plate 18 to slide upward, and the motor 2 is restarted to drive the four boxes 2 4 to rotate again, and the light source board material that is about to be pressed is moved to the bottom of the pressing plate 18 to prepare for the next round of pressing. The pressed light source board will be moved to another exposed access hole 5. During the pressing of the light source board by the pressing plate 18, the pressed light source board can be removed from the corresponding box 2 4 and replaced with the light source board material that needs to be pressed, so as to ensure the continuous pressing work.

[0033] When it is necessary to press-fit light source panels with different shapes, two motors 2 13 in a box body 2 4 are started successively, and the two motors 2 13 will drive the two gears 14 fixedly connected thereto, and with the cooperation of the four gears 14, the two threaded sleeves 11 will be driven to rotate, and the four threaded rods 12 will slide in the two threaded sleeves 11. During the sliding process of the four threaded rods 12, four baffles 15 are driven, and after the four baffles 15 are adjusted to appropriate positions, the two motors 2 13 will be automatically closed. After the four baffles 15 on one box body 2 4 are adjusted, the other three box bodies 2 4 are adjusted in the same way. After the four baffles 15 on each box body 2 4 are adjusted, the multiple baffles 15 on the four box bodies 2 4 for limiting the position of the light source panels can be put into use after being adjusted, so as to adapt to different light source panels and improve the flexibility of equipment use.

[0034] Compared with the related art, the light source board pressing device of the LED bulb provided by the utility model has the following beneficial effects:

[0035] In the utility model, four box bodies 2 4 are arranged in box body 1, and the tops of the four box bodies 2 4 are used to place the light source panels that need to be pressed. Driven by motor 1 2, the positions of the four box bodies 2 4 are gradually changed and are positioned under the pressure plate 18 in turn to be pressed. This makes it convenient to take and replace the light source panels and saves time. At the same time, starting multiple motors 2 13 can adjust the positions of multiple baffles 15, thereby facilitating the multiple baffles 15 to adapt to different light source panels and improving the flexibility and applicability of the equipment.
