DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the utility model provides the following technical solutions: a rapid welding device for a PCB board, comprising: an operating table 1, a bearing plate 2 is provided on the operating table 1, a support block 3 is installed between the bearing plate 2 and the operating table 1, a welding assembly is provided above the support block 3, a mounting groove 4 is provided on the bearing plate 2, a mounting plate 5 is provided in the mounting groove 4, a PCB board body 6 is provided on the upper end surface of the mounting plate 5, clamping assemblies are provided on both sides of the PCB board body 6, a limit assembly is provided between the mounting plate 5 and the bearing plate 2, a vertical first thread groove 9 is provided at the bottom end of the bearing plate 2, a first threaded rod 10 is screwed through the first thread groove 9, and the top end of the first threaded rod 10 is connected to the lower end surface of the mounting plate 5 through a bearing.

[0023] Furthermore, the clamping assembly includes a fixing plate 11, a second threaded rod 13 and a clamping plate 14. The fixing plate 11 is installed on the upper end surface of the mounting plate 5. A transverse second threaded groove 12 is opened on the fixing plate 11. The second threaded rod 13 is screwed through the second threaded groove 12. The clamping plate 14 is installed on one end of the second threaded rod 13 close to the PCB board body 6.

[0024] Furthermore, the limiting assembly includes a limiting groove 7 and a limiting block 8. The limiting groove 7 is vertically opened on the inner wall of the bearing plate 2, and the limiting block 8 is fixed on the side wall of the mounting plate 5. The limiting groove 7 and the limiting block 8 are adapted to each other.

[0025] Through the above technical solution:

[0026] When in use, place the PCB board body 6 on the mounting plate 5, screw the second threaded rod 13, and drive the clamping plate 14 to move through the interaction between the second threaded rod 13 and the second threaded groove 12, until the clamping plate 14 fits the side wall of the PCB board body 6, and clamps the PCB board body 6, so that the PCB board body 6 is not easy to shift during welding. The easily movable clamping plate 14 is convenient for clamping PCB board bodies 6 of different models, thereby improving the flexibility of the equipment. When welding, screw the first threaded rod 10, and drive the clamping plate 14 to move through the interaction between the first threaded rod 10 and the first threaded groove 9. The movable mounting plate 5 moves downward, thereby allowing the PCB board body 6 to enter the mounting groove 4. The mounting plate 5 blocks the spatter generated during welding to ensure the safety of welding. After welding is completed, the first threaded rod 10 is screwed in the opposite direction, and the first threaded rod 10 moves the mounting plate 5 upward, thereby allowing the PCB board body 6 to emerge from the mounting groove 4, making it easier to remove and install the PCB board body 6. When the mounting plate 5 moves, the limit block 8 moves in the limit groove 7, thereby limiting the movement of the mounting plate 5, so that the mounting plate 5 only moves up and down, and is not easy to shake left and right, thereby improving the stability of the equipment.

[0027] See also Figure 1 , Figure 3 and Figure 6 As shown, support rods 15 are installed on both sides of the upper end surface of the operating table 1, a support plate 16 is installed on the top of the support rod 15, a linear motor 17 is installed on the lower end surface of the support plate 16, an electric telescopic rod 18 is installed on the output end of the linear motor 17, a connecting plate 19 is installed on the output end of the electric telescopic rod 18, a rotating component is installed on the connecting plate 19, and a movable plate 22 is installed on the output end of the rotating component.

[0028] Furthermore, the rotating assembly includes a rotating motor 20 and a rotating shaft 21 . The rotating motor 20 is mounted on the connecting plate 19 . The rotating shaft 21 is connected to the output end of the rotating motor 20 . One end of the rotating shaft 21 away from the rotating motor 20 is connected to the movable plate 22 .

[0029] Furthermore, the welding assembly includes multiple welding pipe heads 23, which are all installed on the movable plate 22. The movable plate 22 is provided with multiple third thread grooves 24, and the outer walls of the multiple welding pipe heads 23 are provided with external threads 25. The third thread grooves 24 and the external threads 25 are adapted to each other.

[0030] Through the above technical solution:

[0031] When welding, start the linear motor 17 and the electric telescopic rod 18. The linear motor 17 drives the electric telescopic rod 18 and the welding assembly to move in the horizontal direction, and the electric telescopic rod 18 drives the welding assembly to move in the vertical direction. Then start the rotating motor 20. The rotating motor 20 drives the movable plate 22 to rotate through the rotating shaft 21. The rotating movable plate 22 adjusts the position of the welding pipe head 23. By selecting multiple welding pipe heads 23, the size and shape of the welding pipe head 23 can be flexibly adjusted as needed to adapt to PCB board bodies 6 of different sizes and shapes. This ensures efficient and accurate welding of PCB board bodies 6 of various sizes and shapes. When disassembling the welding pipe head 23, screw the welding pipe head 23, separate the third thread groove 24 and the external thread 25, and then remove the welding pipe head 23, so that it is convenient to clean and replace the welding pipe head 23.
