[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3 , an automatic solder paste applying mechanism, comprising:

[0021] A fixed housing 1, wherein the bottom end of the fixed housing 1 is fixedly connected to a fixed tube 2, and the solder paste leaves the fixed housing 1 through the fixed tube 2;

[0022] The extrusion structure includes a motor 3 fixedly connected to the top of the fixed shell 1, and the output end of the motor 3 is fixedly connected to the rotating rod 5, which penetrates the upper inner wall of the fixed shell 1 and extends to the interior of the fixed shell 1. A fixed piston 7 is slidably connected between the inner walls of the fixed shell 1, and the fixed piston 7 and the fixed shell 1 are sealed, which can prevent the solder paste from flowing out when not squeezed, and the top of the fixed piston 7 is fixedly connected to the threaded rod 6. One end of the rotating rod 5 located on the inner side of the fixed shell 1 is threadedly sleeved on the outer side of the fixed shell 1, and a stirring structure is provided on the fixed piston 7. When the motor 3 is started, the output end of the motor 3 drives the rotating rod 5 to rotate. Since the threaded rod 6 and the fixed piston 7 cannot rotate, the rotation of the rotating rod 5 will cause the threaded rod 6 to move under the action of the thread, so that the fixed piston 7 moves accordingly. When the fixed piston 7 moves downward, the solder paste in the fixed shell 1 will be squeezed toward the fixed tube 2;

[0023] The stirring structure includes a connecting groove 12 opened on the bottom wall of the fixed piston 7, and a connecting block 13 is rotatably connected on the upper inner wall of the connecting groove 12, and the position of the connecting block 13 corresponds to the threaded rod 6. The top of the connecting block 13 is fixedly connected to a fixing rod 8, which passes through the connecting groove 12 and the threaded rod 6 and extends into the interior of the rotating rod 5, and the fixing rod 8 and the threaded rod 6 are rotatably connected. One end of the fixing rod 8 located inside the rotating rod 5 is fixedly connected to a fixing block 9, and the fixing block 9 is slidably connected to the inner wall of the rotating rod 5, and a plurality of stirring rods 14 are fixedly connected to the side wall of the connecting block 13. When the threaded rod 6 moves, the fixing rod 8 moves accordingly, so that the relative position of the fixing rod 8 and the rotating rod 5 remains unchanged. At the same time, the fixing rod 8 will rotate under the cooperation of the fixing block 9 and the rotating rod 5, so that the connecting block 13 and the plurality of stirring rods 14 rotate together, stirring the solder paste in the fixed shell 1 to prevent the solder paste from solidifying;

[0024] The end of each stirring rod 14 away from the connecting block 13 is fixedly connected to a scraping block 15, and the end of each scraping block 15 away from the stirring rod 14 is arranged in contact with the inner wall of the connecting groove 12, and the side wall of each scraping block 15 is provided with a chamfer. When the stirring rod 14 rotates, the scraping block 15 rotates accordingly to scrape the inner wall of the connecting groove 12 to prevent the solder paste from adhering to the inner wall of the connecting groove 12. At the same time, the chamfer arrangement facilitates the scraping of the solder paste; a sliding block 10 is fixedly connected to the side wall of the fixed block 9, and a sliding groove 11 corresponding to each sliding block 10 is opened on the inner side wall of the rotating rod 5. The sliding block 10 and the sliding groove 11 can facilitate the movement of the rotating rod 5;

[0025] The top of the fixed shell 1 is fixedly connected to a protective shell 4, and the protective shell 4 completely wraps the motor 3. The motor 3 is provided with a corresponding controller. The controller and the motor 3 are matching existing technologies. The motor 3 can be controlled by the controller, and the protective shell 4 can protect the motor 3 to prevent damage to the motor 3; a thread is provided on the side wall of the fixed tube 2, and the fixed shell 1 is fixedly connected to the welding device through the thread on the fixed tube 2.

[0026] In the present invention, when the device is in use, the fixed shell 1 is first fixedly connected to the welding device through the thread on the fixed tube 2. During the welding process, the motor 3 is started. After the motor 3 is started, the output end of the motor 3 drives the rotating rod 5 to rotate. Since the threaded rod 6 and the fixed piston 7 cannot rotate, the rotation of the rotating rod 5 will cause the threaded rod 6 to move under the action of the thread, so that the fixed piston 7 moves accordingly. When the fixed piston 7 moves downward, the solder paste in the fixed shell 1 will be squeezed toward the fixed tube 2, so that the solder paste enters the welding device from the fixed tube 2. The screw threaded rod 6 is placed inside, and when the screw threaded rod 6 moves, the fixed rod 8 moves accordingly, so that the relative position of the fixed rod 8 and the rotating rod 5 remains unchanged. At the same time, the fixed rod 8 rotates with the cooperation of the fixed block 9 and the rotating rod 5, so that the connecting block 13 and the plurality of stirring rods 14 rotate together, stirring the solder paste in the fixed housing 1 to prevent the solder paste from solidifying. When the stirring rod 14 rotates, the scraping block 15 rotates accordingly to scrape the inner wall of the connecting groove 12 to prevent the solder paste from adhering to the inner wall of the connecting groove 12. The chamfered setting also facilitates the scraping of the solder paste.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
