However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0032] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0033] Please see Figures 1 to 6 An automatic soldering device for speaker terminals with a nitrogen protection structure, in this embodiment including:

[0034] A soldering assembly 2 for horn terminal soldering includes a soldering head 3 for horn terminal soldering and an electric push rod 4 for providing power for automatic soldering of the horn terminal. The soldering head 3 is an existing soldering facility that can perform soldering by contacting electrical connectors. The soldering head 3 is not an innovative structure to be protected by this utility model. The specific functional principle is not described in detail. The horn terminal and the electrical connection line are transported by an external conveying device, so that the horn terminal and the electrical connection line are in contact. The electric push rod 4 provides power, and the soldering head 3 moves automatically during the transmission process to realize the automatic soldering of the horn terminal.

[0035] The protective component 5 is used to spray nitrogen to protect the solder of the horn terminal. In order to improve the soldering quality of the horn terminal, it is often necessary to spray nitrogen for anti-oxidation treatment. Thanks to the design of the protective component 5, nitrogen can be sprayed to provide an anti-oxidation environment for the soldering equipment to process the horn terminal, thereby improving the soldering quality of the horn terminal. The protective component 5 includes a hollow connecting ring 6 and a flexible connecting tube 10. The outer periphery of the connecting tube 10 is connected to the connecting ring 6. Nitrogen can be introduced into the connecting tube 10 through an external pump, so that the nitrogen is introduced into the inner cavity of the connecting ring 6.

[0036] The bottom surface of the connecting ring 6 is equipped with several inclined nozzles for spraying nitrogen to protect the solder of the horn terminals. By spraying nitrogen through these nozzles, the horn terminals undergoing soldering are protected against oxidation, thereby improving the soldering quality of the horn terminals. The upper part of the connecting ring 6 is provided with a limiting plate 9. A movable plate 8 is slidably connected to the top surface of the limiting plate 9. A connecting plate 7 is welded to the bottom surface of the movable plate 8. The side of the connecting plate 7 is welded to the connecting ring 6. The solder head 3 is located in the inner cavity of the connecting ring 6. An installation plate 11 is welded to the side of the limiting plate 9. The solder head 3 is installed on the bottom surface of the installation plate 11.

[0037] The solder head 3 is fixed to the bottom surface of the mounting plate 11. The position of the solder head 3 can be fixed by welding, bolt connection or other methods. The specific fixing connection method can be determined according to the actual use requirements. The side of the limiting plate 9 away from the mounting plate 11 is threaded with a clamping bolt for pressing against the moving plate 8. In order to adapt to the nitrogen gas requirements during the soldering process of the horn terminal, the moving plate 8 can be moved along the path of the limiting plate 9. With the connection of the connecting plate 7, the vertical position of the connecting ring 6 can be adjusted, thereby controlling the position of several nozzles spraying nitrogen gas, so that several nozzles can fully cover the horn terminal during the soldering process with nitrogen gas, enhance the anti-oxidation effect during the soldering process of the horn terminal, and improve the soldering quality of the horn terminal by the equipment.

[0038] A positioning plate 12 is provided on the upper part of the mounting plate 11. An electric push rod 4 is embedded in the top surface of the positioning plate 12. The fixed end of the electric push rod 4 is connected to the positioning plate 12 by bolts, and the moving end of the electric push rod 4 is connected to the mounting plate 11. The top wall of the mounting plate 11 is connected to the moving end of the electric push rod 4 by bolts. Positioning ears 13 are welded to the top and bottom of the positioning plate 12. A processing table 1 is provided at the lower part of the solder head 3. A support plate 18 is welded to the top surface of the processing table 1. The sides of the two positioning ears 13 are threadedly connected to the support plate 18 by bolts. The sides of the support plate 18 are provided with several threaded slots for bolt threading, so that the bolts threadedly connected to the positioning ears 13 can extend into different threaded slots, providing conditions for adjusting the vertical position of the positioning plate 12. Two clamping blocks 15 are welded to the end face of the positioning plate 12. A clamping plate 14 is welded to the end face of the two clamping blocks 15. The sides of the clamping plate 14 are slidably connected to the support plate 18.

[0039] Two sliding slots for sliding the clamping block 15 are provided on the side of the support plate 18 near the clamping plate 14. Two L-shaped symmetrically arranged connecting brackets 16 are welded to the side of the mounting plate 11. The inner walls of the two connecting brackets 16 are arranged adjacent to each other. The sides of the two connecting brackets 16 are slidably connected to the inner walls of the two sliding slots. Movable plates 17 are welded to the adjacent sides of the two connecting brackets 16. The sides of the movable plates 17 are slidably connected to the support plate 18. The initial position of the solder head 3 can be adjusted by adjusting the vertical position of the positioning plate 12. By shortening the solder spacing between the solder head 3 and the horn terminal, the travel of the moving end of the electric push rod 4 is shortened, reducing energy consumption and achieving energy saving and environmental protection of the equipment. When the mounting plate 11 moves vertically, the movable plate 17 and the two connecting brackets 16 move down along the path of the support plate 18, which enhances the vertical movement stability of the solder head 3 during the transmission process.

[0040] Solder tip 3 and electric push rod 4 are conventional instruments. Their working principle, size and model are not related to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. In order to facilitate the inspection, maintenance and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. In addition, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0041] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0042] Working principle

[0043] In use, the automatic soldering equipment for horn terminals with a nitrogen protection structure is operated by an external pump that inputs nitrogen into the connecting ring 6 through a connecting pipe 10. The nitrogen is then sprayed out through several nozzles. The moving plate 8 moves along the path of the limiting plate 9. With the connection between the connecting plate 7 and the connecting ring 6, the position of the nozzles is adjusted so that the nitrogen sprayed by the nozzles fully covers the horn terminals during the soldering process, thereby providing an anti-oxidation effect for the soldering of the horn terminals.

[0044] This allows the clamping plate 14 and the two clamping blocks 15 to move along the path of the support plate 18. With the connection of the two positioning ears 13, the vertical position of the positioning plate 12 can be adjusted. By reducing the initial distance between the solder head 3 and the speaker terminal, the travel of the moving end of the electric push rod 4 is reduced, energy consumption is reduced, and the energy-saving and environmentally friendly nature of the equipment is achieved.

[0045] During the vertical movement of the mounting plate 11, the movable plate 17 and the two connecting brackets 16 move down along the path of the support plate 18, allowing the solder head 3 to move smoothly.
