After applying the solder paste, the machine is used to solder the surface of the electronic components. This not only increases the workload of the workers but also reduces the soldering efficiency of the electronic components. Furthermore, the amount of solder paste used cannot be precisely controlled, resulting in waste and reducing the overall practicality of the soldering machine. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an automatic solder feeding mechanism for a soldering machine, including a base 1, a slide block 2 slidably mounted on the base 1, a mounting plate 3 vertically slidably mounted on the bottom surface of the slide block 2, and a soldering gun 4 fixedly mounted on the mounting plate 3; a collar 8 is also provided on the mounting plate 3, a rotating arm 10 is rotatably mounted on the collar 8, a liquid feeding cylinder 11 is fixedly mounted on the rotating arm 10, and a liquid feeding mechanism for adding solder paste to the liquid feeding cylinder 11 is provided on the rotating arm 10. The effect achieved by the above components is that by utilizing the liquid feeding mechanism, the solder paste can flow into the liquid feeding cylinder 11 under the action of the liquid feeding mechanism, thereby dripping the solder paste onto the electronic components through the liquid feeding cylinder 11, and thus soldering the surface of the electronic components. This reduces the workload of the workers, improves the soldering efficiency of the electronic component surface, and improves the practicality of the entire soldering machine.

[0024] The following is a detailed explanation of its overall setup and function.

[0025] A fixed arm 9 is fixedly installed on the collar 8, and a rotating arm 10 is rotatably mounted on the fixed arm 9. A positioning bolt 24 is threaded onto the fixed arm 9. By using the rotating arm 10, the tilt angle of the liquid delivery cylinder 11 on the rotating arm 10 can be adaptively adjusted, and by using the positioning bolt 24, the adjusted angle of the rotating arm 10 can be locked, thereby improving the stability of the rotating arm 10.

[0026] The liquid delivery mechanism includes a mounting ring 12, which is threaded onto the rotating arm 10 via a threaded rod 13. An injection cylinder 14 is snapped into the interior of the mounting ring 12. A cap 15 is threaded onto the top end face of the injection cylinder 14. An inlet pipe 16 and an outlet pipe 17 are connected to the cap 15, and the outlet pipe 17 is connected to the delivery cylinder 11. By utilizing the inlet pipe 16 on the injection cylinder 14, solder paste can flow into the injection cylinder 14 along the inlet pipe 16 under the action of the injection cylinder 14. Furthermore, by utilizing the reverse operation of the injection cylinder 14, the solder paste in the injection cylinder 14 can flow into the paper tube delivery cylinder 11 along the outlet pipe 17, thus achieving the effect of automatically delivering the solder paste in the delivery cylinder 11.

[0027] A piston 22 is disposed inside the injection cylinder 14, which is reciprocated within the injection cylinder 14 by a drive assembly. By controlling the sliding of the piston 22 within the injection cylinder 14 using the drive assembly, the piston 22 is able to absorb solder paste and deliver solder paste within the injection cylinder 14.

[0028] The drive assembly includes a connecting bracket 18 fixedly mounted on the side of the mounting ring 12. An electric push rod 19 is fixedly mounted on the connecting bracket 18. A connecting plate 20 is fixedly mounted on the output end of the electric push rod 19. A stopper rod 21 is fixedly mounted on the connecting plate 20. The other end of the stopper rod 21 is fixedly mounted on a piston 22. By utilizing the electric push rod 19, the piston 22 in the injection cylinder 14 can slide along the axial direction of the injection cylinder 14 under the action of the electric push rod 19, thereby achieving the effect of precisely controlling the amount of solder paste used as needed.

[0029] A spring 23 is fitted around the circumference of the plunger 21. One end of the spring 23 is fixedly connected to the syringe 14, and the other end is fixedly connected to the piston 22. By utilizing the spring 23, the piston 22 is provided with the power to return to its original position.

[0030] A mounting bracket 5 is fixedly mounted on the mounting plate 3, and a cylinder 6 is fixedly mounted on the mounting bracket 5. A lifting plate 7 is fixedly mounted on the output end of the cylinder 6, and a collar 8 is fixedly mounted on the lifting plate 7, and the collar 8 is slidably sleeved on the welding torch 4. By utilizing the cylinder 6, the lifting plate 7 can slide vertically under the action of the cylinder 6, thereby allowing the collar 8 to slide along the axial direction of the welding torch 4. This allows for adaptive adjustment of the height of the liquid delivery cylinder 11 on the rotating arm 10, thus enabling the welding torch 4 to lift the liquid delivery cylinder 11 on the rotating arm 10 when welding electronic components, thereby storing the liquid delivery tube and improving the protection of the liquid delivery cylinder 11.

[0031] Working principle: When solder paste needs to be added to electronic components using the liquid delivery cylinder 11, the piston 22 in the injection cylinder 14 can slide along the axis of the injection cylinder 14 under the action of the electric push rod 19 on the connecting frame 18, so that the solder paste can flow into the injection cylinder 14 in a metered manner through the liquid inlet pipe 16.

[0032] Then, by means of the reverse action of the electric push rod 19, the piston 22 can slide in the reverse direction along the axis of the injection cylinder 14, thereby pushing the solder paste in the injection cylinder 14 along the liquid outlet tube 17 into the liquid delivery tube 11, thereby dripping the solder paste onto the corresponding position on the electronic component by means of the liquid delivery tube 11.

[0033] It is worth mentioning that solenoid valves should be installed on the inlet pipe 16 and the outlet pipe 17 to ensure that the solder paste flows along the above steps when the piston 22 in the injection cylinder 14 slides back and forth.

[0034] After the electronic components are added to the solder paste, the lifting plate 7 can slide vertically under the action of the cylinder 6, so that the collar 8 can slide along the axis of the soldering gun 4. This allows the height of the liquid delivery cylinder 11 on the rotating arm 10 to be adaptively adjusted. In this way, the soldering gun 4 can lift the liquid delivery cylinder 11 on the rotating arm 10 when soldering electronic components, thereby storing the liquid delivery tube and improving the protection of the liquid delivery cylinder 11.
