[0048] The embodiment of the present utility model, referring to Figures 1-8 As shown, a wave soldering nozzle structure 10 and a wave soldering device are provided.

[0049] In the related art, the turbulence wave generating component 120 and the horizontal wave generating component 130 of the wave soldering equipment are independently arranged and are respectively driven by a turbulence pump and a horizontal pump. The turbulence pump drives the tin liquid in the tin furnace 400 to eject from the turbulence wave nozzle 1201 to form a turbulence wave. The turbulence wave nozzle 1201 is designed with a specific shape and aperture to generate a rotating airflow and eddy current, thereby disturbing the gas flow and heat distribution in the welding area; the horizontal pump drives the tin liquid in the tin furnace 400 to eject from the horizontal wave nozzle to form a horizontal wave. The horizontal wave nozzle 1301 is designed with a specific shape and aperture to maintain the temperature of the welding area and the stability of the gas flow, thereby achieving uniform heat distribution.

[0050] According to an embodiment of the present invention, please refer to Figure 1 and Figure 2 According to the wave soldering nozzle structure 10 of the embodiment of the present invention, it includes a base 110 and a crest generating mechanism. The base 110 is formed with a guide cavity, which is suitable for communicating with the tin furnace through a driving device. The crest generating mechanism is installed on the base 110. The crest generating mechanism is formed with a crest nozzle connected to the guide cavity, and the crest nozzle is formed with a turbulent wave area and a flat wave area.

[0051] In this embodiment, the guide cavity of the base 110 can be connected to the tin furnace 400 of the wave soldering equipment to supply solder into the guide cavity. The solder in the guide cavity can be sprayed into the welding area through the turbulent wave area and the smooth wave area respectively to form turbulent waves and smooth waves. The wave soldering nozzle structure 10 of this embodiment only needs to use a driving motor to transport the solder into the guide cavity and spray it from the wave nozzle to realize welding work in the turbulent wave area and the smooth wave area, thereby improving system integration, simplifying operation steps, reducing operation complexity, and thus improving work efficiency. In the entire welding process, only one driving motor is needed to transport the solder, which reduces energy consumption and production costs compared to the traditional two motors that drive the turbulent wave generating component and the smooth wave generating component respectively.

[0052] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the spoiler wave region is provided with a spoiler wave generating component 120 , and the spoiler wave generating component 120 forms a spoiler wave nozzle 1201 ; the flat wave region is provided with a flat wave generating component 130 , and the flat wave generating component 130 forms a flat wave nozzle 1301 .

[0053] The spoiler wave generating assembly 120 and the peaceful wave generating assembly 130 are integrated on the same base 110 to realize the integration of spoiler wave and peaceful wave, that is, the spoiler wave assembly and the peaceful wave assembly can work simultaneously.

[0054] The spoiler wave nozzle 1201 is a component of the spoiler wave generating assembly 120. It sprays the molten tin onto the soldering area and generates spoiler waves, thereby enhancing the mixing of the molten tin and improving soldering quality. The spoiler wave nozzle 1201 is typically designed with multiple small holes or slits, which disperse the molten tin into multiple small streams, generating spoiler waves. The spoiler wave nozzle 1201 can also adjust the spray angle and effect by changing parameters such as the position, size, and shape of the holes, thereby meeting the needs of different occasions.

[0055] The flat wave nozzle 1301 is a component of the flat wave generating assembly 130. It evenly sprays the molten tin onto the weld area, maintaining its stability and fluidity during the spraying process, thereby ensuring accurate and stable welding. The flat wave nozzle 1301 is typically designed in a long strip shape. This ensures that the molten tin evenly covers the entire weld area during spraying, preventing drastic fluctuations in the molten tin due to inertia and ensuring weld quality.

[0056] It is easy to understand that the integrated setting can reduce the number of components, simplify the overall structure, and reduce the complexity of assembly and maintenance; through the integrated setting, the unified control of the spoiler wave and the smooth wave can be more conveniently achieved, thereby improving the convenience and flexibility of operation; the spoiler wave and the smooth wave can work simultaneously and coordinate with each other, thereby improving the stability and efficiency of the welding process, and integrating the spoiler wave generating component 120 and the smooth wave generating component 130 on the same base 110 can save space and reduce the overall volume.

[0057] During the welding process, disturbed wave welding is usually performed first to promote the mixing and solidification of welding materials by disturbing the flow state of gas or liquid in the welding area; then flat wave welding is performed to control the temperature distribution of materials in the welding area through stable solder flow, thereby improving welding quality.

[0058] It can be understood that the wave soldering nozzle structure 10 of the embodiment of the present invention includes a base 110, a spoiler wave generating component 120 and a smooth wave generating component 130, the base 110 is formed with a guide cavity, the spoiler wave generating component 120 and the smooth wave generating component 130 are arranged on the base 110, the spoiler wave generating component 120 is provided with a spoiler wave nozzle 1201, and the smooth wave generating component 130 is provided with a smooth wave nozzle 1301, and the spoiler wave nozzle 1201 and the smooth wave nozzle 1301 are both connected to the guide cavity. Only one driving motor is needed to transport solder into the guide cavity to realize the welding work of the spoiler wave nozzle 1201 and the smooth wave nozzle 1301, which simplifies the operation steps, reduces the operation complexity, and thus improves the work efficiency. In the entire welding process, only one driving motor is needed to transport the solder, which reduces the energy consumption and reduces the production cost compared with the traditional two motors that drive the spoiler wave generating component 120 and the smooth wave generating component 130 respectively.

[0059] Since the operation of the spoiler wave generating component 120 and the horizontal wave generating component 130 can be realized by a single driving motor, compared with the previous design in which the spoiler wave generating component 120 and the horizontal wave generating component 130 are independently driven by driving motors, one driving motor, impeller, inverter and guide groove can be reduced, thereby greatly saving the manufacturing cost and maintenance cost of the wave soldering equipment.

[0060] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the turbulent wave generating assembly 120 and the flat wave generating assembly 130 are arranged side by side along the width direction of the base 110 .

[0061] It will be appreciated that in this embodiment, arranging the turbulent wave generating assembly 120 and the smooth wave generating assembly 130 side by side along the width direction of the base 110 can effectively utilize space and improve welding efficiency. Furthermore, by reducing the length of the turbulent wave generating assembly 120 and the smooth wave generating assembly 130, the contact area between the molten tin and the air during the spraying of the molten tin by the turbulent wave and smooth wave nozzles can be reduced, thereby reducing the oxidation rate of the tin slag, avoiding the generation of excessive tin slag, and improving the utilization rate of the solder.

[0062] In some embodiments, the spraying angles of the turbulent wave generating assembly 120 and the horizontal wave generating assembly 130 can be reasonably adjusted to ensure that the tin liquid is directly sprayed onto the welding area, reducing the area of ​​contact with the air during the spraying process, or a more sophisticated nozzle structure can be designed to control the range and speed of the spraying to ensure that the tin liquid solidifies quickly after being sprayed onto the welding area, reducing the time of exposure to the air. The spraying pressure and amount of the turbulent wave generating assembly 120 and the horizontal wave generating assembly 130 can also be adjusted to avoid excessive spraying that causes the tin liquid to splash, thereby reducing the chance of contact with the air; or inert gas (such as nitrogen) can be used for protection during the welding process to effectively reduce the contact between the tin liquid and the air and reduce the oxidation rate.

[0063] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the spoiler wave generating assembly 120 includes a front baffle 121, a spoiler 122 and a middle baffle 123 arranged in sequence, the spoiler 122 is provided with a spoiler wave nozzle 1201, the flat wave generating assembly 130 includes a flat plate 131 and a rear baffle 132, and a spoiler cavity is formed between the front baffle 121, the spoiler 122 and the middle baffle 123, and a flat cavity is formed between the middle baffle 123, the flat plate 131 and the rear baffle 132.

[0064] It will be appreciated that in this embodiment, the spoiler wave generating assembly 120 and the flat wave generating assembly 130 are arranged closely together, i.e., a spoiler cavity is formed between the front baffle 121, the spoiler 122, and the middle baffle 123, and a flat flow cavity is formed between the middle baffle 123, the flat flow cavity 131, and the rear baffle 132. The spoiler cavity and the flat flow cavity are separated by the middle baffle 123. This compact structural arrangement enables the spoiler cavity and the flat flow cavity to perform their respective unique functions during the welding process, effectively controlling and optimizing the flow state of the tin liquid, thereby improving the accuracy and stability of welding. This design helps improve welding quality, reduces volume, and implements complex operating processes within a limited space.

[0065] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the spoiler 122 and the flattening plate 131 are disposed on both sides of the middle baffle 123 , and both the spoiler 122 and the flattening plate 131 abut against the middle baffle 123 .

[0066] It is understood that in this embodiment, the spoiler wave generating assembly 120 and the smooth wave generating assembly 130 can share the same middle baffle 123, and there is no gap between the spoiler wave generating assembly 120 and the smooth wave generating assembly 130. By sharing the same middle baffle 123 and eliminating the gap between the spoiler wave generating assembly 120 and the smooth wave generating assembly 130, the two assemblies can be tightly combined together, reducing additional space requirements. This can minimize the overall volume of the wave soldering nozzle structure 10.

[0067] This compact design not only saves space on the equipment but also reduces the area of ​​contact between the solder and air during the soldering process, reducing the risk of oxidation and contamination, thereby improving soldering quality and efficiency. Furthermore, by reducing the area of ​​contact between the solder and air, the generation of tin dross can also be reduced. The generation of tin dross not only affects soldering quality but also increases the difficulty and time of subsequent cleaning work. Therefore, reducing the generation of tin dross can improve the maintainability of the equipment, reduce maintenance and cleaning costs, improve the soldering quality of wave soldering equipment, and ensure good soldering results.

[0068] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the height of the middle baffle 123 is lower than that of the rear baffle 132 so that the spoiler cavity and the flat flow cavity are connected.

[0069] It can be understood that in this embodiment, since there is no gap between the spoiler wave generating assembly 120 and the flat wave generating assembly 130, and by setting the height of the middle baffle 123 to be lower than the height of the rear baffle 132, the solder sprayed from the spoiler wave generating assembly 120 can flow into the flat flow cavity composed of the middle baffle 123, the flat flow plate 131 and the rear baffle 132 to a certain extent, forming a flat flow wave.

[0070] In some embodiments, the solder flows directly through the flow guide cavity and is ejected from the advection wave nozzle 1301. In this case, the solder flows directly into the advection cavity through the flow guide cavity and is then ejected from the advection wave nozzle 1301, forming a advection wave. This approach ensures that the solder flow is effectively controlled, forming a more stable and uniform advection wave, which is beneficial for improving welding quality.

[0071] In other embodiments, the solder ejected from the turbulent wave nozzle 1201 flows into the advection cavity to form a flat wave. By designing the middle baffle 123 to be lower than the rear baffle 132, the solder ejected from the turbulent wave generating assembly 120 can flow into the advection cavity to a certain extent, forming a flat wave with the advection plate 131. This approach can also help the solder flow more evenly, reduce the generation of defects such as bubbles and oxides, and improve welding quality and stability.

[0072] In other embodiments, part of the flat wave is formed by the solder directly ejected from the flat wave nozzle 1301 through the guide cavity, and the other part is formed by the solder ejected from the turbulent wave nozzle 1201 flowing into the flat flow cavity. It can be designed according to actual application requirements.

[0073] In this embodiment, through the connection design between the turbulence chamber and the horizontal flow chamber, the solder ejected from the turbulence wave nozzle 1201 can flow into the horizontal flow chamber to form a horizontal wave. This design helps to make the tin liquid flow and mix more smoothly during the welding process, thereby improving the welding quality and stability, and also improving the welding efficiency. When the solder can flow smoothly from the turbulence chamber into the horizontal flow chamber, the flow state of the solder can be better controlled to ensure that the solder is evenly distributed in the welding area, which helps to reduce the generation of defects such as bubbles and oxides, and improve the quality and stability of welding. In addition, the tin liquid flows and mixes more evenly in the horizontal flow chamber, which can make the welding process more stable and reliable, reduce the influence of adverse factors on the welding results, and thus improve the overall performance of the welding process.

[0074] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the height of the middle baffle 123 is adjustable.

[0075] It can be understood that in this embodiment, by adjusting the height of the middle baffle 123, the flow rate and speed of the solder ejected from the turbulent wave nozzle 1201 to the horizontal flow cavity can be flexibly controlled, so that the operator can adjust the flow of the solder according to actual needs during the welding process to achieve the best welding effect.

[0076] On the one hand, by adjusting the height of the middle baffle 123, the amount of solder flowing into the horizontal flow cavity can be controlled, thereby affecting the distribution uniformity and thickness of the solder in the welding area, and further affecting the welding quality; on the other hand, adjusting the height of the middle baffle 123 can also adjust the speed at which the solder flows into the horizontal flow cavity, which is crucial for controlling the formation of the molten pool and the flow of liquid metal during the welding process, and helps to improve the welding stability; on the other hand, by adjusting the height of the middle baffle 123, the heat distribution in the welding area can also be affected, which helps to control the welding temperature and avoid overheating or overcooling, thereby improving the welding quality.

[0077] According to one embodiment of the present invention, a third positioning bolt is further included. The middle baffle 123 is provided with a third adjustment long hole along the height direction. The third positioning bolt is suitable for passing through the third adjustment long hole and connecting to the base 110 to adjust the height of the middle baffle 123.

[0078] To change the width of the middle baffle 123, simply loosen the third positioning bolt, move the middle baffle 123 to the desired height, and then tighten the third positioning bolt to secure the height. The third positioning bolt and the third adjustment slot allow the height of the middle baffle 123 to be easily adjusted to meet varying welding requirements and workpiece characteristics.

[0079] In some optional embodiments, the height of the rear baffle 132 is adjustable. By adjusting the height of the rear baffle 132, the height of the flat waves generated by the flat wave generating assembly 130 can be adjusted. At this time, the height of the middle baffle 123 can be adjusted to adapt to the height of the rear baffle 132, that is, the height of the middle baffle 123 is adaptively adjusted when the height of the rear baffle 132 is adjusted.

[0080] By adjusting the height of the rear baffle 132, the height of the flat wave generated by the flat wave generating assembly 130 can be controlled, thereby affecting the atmosphere protection and solder flow in the welding area. Simultaneously, to ensure the stability and uniformity of the flat wave, the height of the middle baffle 123 also needs to be adjusted accordingly to accommodate the height changes of the rear baffle 132. This adaptive adjustment can help optimize the solder flow during the welding process, making it more uniform and stable. By properly adjusting the heights of the rear baffle 132 and the middle baffle 123, more precise welding control can be achieved, improving welding quality and stability.

[0081] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the width of the spoiler 122 is greater than the width of the flat plate 131 .

[0082] It is understandable that, in the present embodiment, the width of spoiler 122 is greater than the width of flattener 131, so the width of spoiler wave is also greater than the width of flattener wave, increases the outlet area of ​​spoiler wave, larger spoiler 122 width can produce larger spoiler wave, and provides more contact area, makes solder fully contact with circuit board to be welded. Simultaneously, larger spoiler 122 width can also enhance the fluidity of solder, by expanding the outlet area of ​​spoiler wave, can reduce resistance, make solder flow more smoothly in welding process, this helps to improve the uniformity and stability of solder in welding process, reduces the factor that may cause welding defect. In addition, by increasing the area of ​​spoiler wave nozzle 1201 panel, can increase the mixing efficiency and heat transfer speed in welding area, this makes welding process more efficient, can improve welding speed.

[0083] In the related art, the welding time of the turbulent wave of the wave soldering equipment is not convenient to adjust, resulting in excessive consumption of solder during the welding process, increasing production costs. It can only be applied to welding workpieces of specific types or sizes, and the application range is extremely limited. In addition, a large amount of tin slag is generated during the welding process, affecting the welding quality.

[0084] The inability to adjust the welding time prevents optimization based on the requirements of different workpieces, resulting in wasted solder. Furthermore, the inability to adjust the welding time means the equipment is only suitable for welding workpieces of specific types or sizes, limiting its application range. For workpieces of other types or sizes, ideal welding results may not be achieved. Excessive welding time can lead to excessive slag, reducing weld quality. The inability to adjust the welding time makes it difficult to control slag generation during the welding process, affecting weld quality and appearance.

[0085] According to one embodiment of the present invention, referring to Figure 1 、 Figure 4 and Figure 5 As shown, the wave soldering nozzle structure 10 includes a base 110, a spoiler wave generating component 120 and an inclination adjustment component 150. The base 110 is formed with a guide cavity. The spoiler wave generating component 120 is rotatably arranged on the base 110. The spoiler wave generating component 120 is provided with a spoiler wave nozzle 1201. The spoiler wave nozzle 1201 is connected to the guide cavity. The inclination adjustment component 150 is provided on the spoiler wave generating component 120. The inclination adjustment component 150 is used to drive the spoiler wave generating component 120 to rotate so as to adjust the angle between the spoiler wave generating component 120 and the base 110.

[0086] In this embodiment, the inclination adjustment member 150 is used to adjust the angle between the spoiler wave generating assembly 120 and the base 110. The inclination adjustment member 150 can adopt a spiral adjustment structure, that is, the angle between the spoiler wave generating assembly 120 and the base 110 can be changed by rotating the adjustment member. This structure can provide a large adjustment range and a relatively simple adjustment process.

[0087] The inclination adjustment member 150 may also adopt a sliding adjustment structure, that is, the angle is changed by sliding the adjustment member in the groove on the base 110. This sliding adjustment structure needs to have a certain guide device to ensure smooth and controllable sliding.

[0088] The inclination adjustment member 150 can also adopt a locking nut structure, that is, the angle between the spoiler wave generating assembly 120 and the base 110 is locked or released by rotating the nut. This locking nut structure can provide a stable angle and prevent accidental adjustment, and has good stability.

[0089] In addition, the inclination adjustment member 150 may also adopt an adjustment pin structure, that is, the angle is changed by inserting or pulling out the adjustment pin. This structure requires a corresponding pin groove or pin hole to fix the adjustment pin.

[0090] In addition, the inclination adjustment member 150 may also adopt other adjustment structures, as long as it can adjust the relative angle between the spoiler wave generating assembly 120 and the base 110. This embodiment does not make any specific limitation to this.

[0091] The angle of the spoiler wave can affect welding time, showing a positive correlation between welding time and the angle. Generally speaking, a larger spoiler wave angle increases welding time, while a smaller spoiler wave angle may shorten welding time. By adjusting the spoiler wave angle, welding time can be controlled to meet the welding time requirements of different workpieces. A suitable spoiler wave angle can also effectively reduce the generation of tin slag. By adjusting the spoiler wave angle, heat transfer and liquid flux flow during welding can be optimized, reducing the generation of solder residue and tin slag, thereby improving welding quality and efficiency.

[0092] The angle of the turbulent wave also affects the fill height of the liquid flux during welding. By adjusting the angle of the turbulent wave, the flow of liquid flux during welding can be controlled, thereby affecting the fill height. This adjustment method can make the welding fill more uniform, improving welding quality and stability.

[0093] The angle of the turbulent wave also affects the welding quality. Different workpieces may require different welding effects, such as weld seam shape and weld strength. By adjusting the angle of the turbulent wave, the heat distribution in the weld area and the flow of liquid flux can be altered during welding, thereby affecting the welding effect. Adjusting the angle of the turbulent wave can achieve a more uniform and stable welding effect, thereby meeting the workpiece's welding quality requirements.

[0094] It can be understood that in this embodiment, the wave soldering nozzle structure 10 includes a base 110, a spoiler wave generating assembly 120 and an inclination adjustment member 150. The base 110 is formed with a guide cavity. The spoiler wave generating assembly 120 is rotatably arranged on the base 110. The spoiler wave generating assembly 120 is provided with a spoiler wave nozzle 1201. The spoiler wave nozzle 1201 is connected to the guide cavity. The inclination adjustment member 150 is arranged on the spoiler wave generating assembly 120. The inclination adjustment member 150 is used to adjust the angle between the spoiler wave generating assembly 120 and the base 110. By adjusting the angle of the spoiler wave, the welding time and welding effect can be controlled, the generation of tin slag can be reduced, and the welding quality can be improved. It has a wide range of applications and can meet the requirements of different workpieces.

[0095] According to one embodiment of the present invention, referring to Figure 1 、 Figure 2 and Figure 4As shown, the spoiler wave generating assembly 120 includes a front baffle 121 and a middle baffle 123 that are relatively arranged, a mounting plate 124 and a spoiler 122, the mounting plate 124 connects the front baffle 121 and the middle baffle 123, the spoiler 122 is rotatably arranged on the mounting plate 124, and a spoiler wave nozzle 1201 is provided on the spoiler 122.

[0096] It is understood that in this embodiment, by providing the spoiler wave nozzle 1201 on the spoiler plate 122, the angle of the spoiler wave can be adjusted by adjusting the angle of the spoiler plate 122 without having to adjust the entire spoiler wave generating assembly 120. This design makes it more convenient and flexible to adjust the angle of the wave crest during welding.

[0097] By rotating the spoiler 122, the direction and angle of the spoiler wave nozzle 1201 will also change accordingly. By increasing or decreasing the angle of the spoiler 122, the spray direction of the spoiler wave nozzle 1201 can be adjusted, thereby controlling the direction and shape of the solder flow during the welding process. The advantage of this design is that the operator can adjust the spoiler wave angle during the welding process by simply adjusting the angle of the spoiler 122, without having to make complex adjustments to the entire spoiler wave generating assembly 120. This improves the convenience and efficiency of adjusting the spoiler wave angle and makes the adjustment of welding parameters more intuitive and accurate.

[0098] The space between front baffle 121, middle baffle 123, and spoiler 122 forms a spoiler chamber. Front baffle 121 and middle baffle 123 are connected via mounting plate 124, and spoiler 122 is pivotally mounted on mounting plate 124. This improves the structural stability of spoiler wave generating assembly 120 and reduces looseness and swinging between components, thereby ensuring stability and consistency during the welding process. By improving the stability of the overall structure, the shape and direction of the spoiler wave during welding can be better controlled, thereby improving welding quality and efficiency.

[0099] According to one embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the height of the front baffle 121 and the height of the spoiler 122 are both lower than the height of the middle baffle 123 .

[0100] It can be understood that in this embodiment, since the circuit board first passes through the spoiler wave and then the flat wave during the welding process, the height of the front baffle 121 is set to be lower than the height of the middle baffle 123, and the spoiler 122 can be tilted toward one side of the front baffle 121, that is, the height of the spoiler 122 close to the front baffle 121 is lower than the height close to the middle baffle 123, so that the spoiler 122 can spray solder toward the front side to achieve welding.

[0101] By setting the tilt angle and height difference of the spoiler 122, the flow direction and shape of the solder during the welding process can be effectively controlled, improving welding efficiency and quality. This design can better meet the welding requirements of high-power devices, reduce the occurrence of adverse phenomena, and ensure stable and reliable welding quality.

[0102] According to one embodiment of the present invention, referring to FIG. Figure 4 As shown, the front baffle 121 includes a vertical section 1211, a guide section 1212 and a connecting section 1213. The vertical section 1211 is installed on the base 110, the guide section 1212 is inclined toward the front side of the spoiler wave generating assembly 120, and the connecting section 1213 connects the vertical section 1211 and the guide section 1212.

[0103] It can be understood that in this embodiment, the vertical section 1211 can be installed on the base 110 for fixation, and when the spoiler 122 sprays solder toward the front side of the spoiler wave generating component 120, a spoiler wave is formed to weld the circuit board. The sprayed solder can also flow back to the tin furnace 400 under the guidance of the guide section 1212. The guide section 1212 guides the reflux of the solder to avoid splashing when the solder falls back into the tin furnace 400 and generating more tin slag. The flow direction of the solder can be effectively controlled and guided back to the tin furnace 400 for recycling, thereby reducing waste and the generation of tin slag.

[0104] By using the tilted guide section 1212 and the principles of fluid mechanics, the solder can be directed back to a designated location to prevent it from splashing and scattering. This not only improves the safety of the soldering process, but also reduces the workload of handling tin slag, thereby improving production efficiency and resource utilization.

[0105] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the wave soldering nozzle structure 10 also includes a flat wave generating component 130 arranged side by side with the turbulent wave generating component 120, and the flat wave generating component 130 includes a rear baffle 132 and a flat plate 131. The rear baffle 132 is arranged opposite to the middle baffle 123. The flat plate 131 connects the middle baffle 123 and the rear baffle 132, and the middle baffle 123, the flat plate 131 and the rear baffle 132 form a flat flow cavity.

[0106] It can be understood that in this embodiment, the wave soldering nozzle structure 10 is also provided with a flat wave generating component 130, which is used to generate flat waves for welding circuit boards. During the welding process, the turbulent waves and the flat waves work together to enable the wave soldering nozzle structure 10 to achieve efficient welding of circuit boards, ensuring welding quality and process stability.

[0107] According to one embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the inclination adjustment member 150 includes a rotating member 151, a first adjusting screw 152 and a second adjusting screw 153. The middle part of the spoiler 122 is rotatably mounted on the mounting plate 124 through the rotating member 151, and the first adjusting screw 152 and the second adjusting screw 153 are arranged on both sides of the rotating member 151.

[0108] It will be appreciated that, in this embodiment, the spoiler 122 is rotatably mounted to the mounting plate 124 via the rotating member 151, and the rotational angle of the spoiler 122 can be adjusted by adjusting the tightening depth of the first adjusting screw 152 and the second adjusting screw 153. Specifically, the first adjusting screw 152 and the second adjusting screw 153 can be inserted through corresponding mounting holes in the spoiler 122 and abut against the mounting plate 124. By adjusting the depth of the first adjusting screw 152 and the second adjusting screw 153 screwed into the mounting holes, the height of the left and right sides of the spoiler 122 can be adjusted, thereby adjusting the angle of the spoiler 122 and adjusting the angle of the spoiler wave.

[0109] When the first adjustment screw 152 and the second adjustment screw 153 are rotated, they push the spoiler 122 against the mounting plate 124, thereby changing the height difference between the left and right sides of the spoiler 122 and adjusting the tilt angle of the spoiler 122. By controlling the depth of these two screws, the tilt angle of the spoiler 122 can be precisely adjusted to meet specific needs and requirements. This design is simple, effective, and easy to operate, allowing for precise adjustment of the angle of the spoiler 122, ensuring that the spoiler 122 performs optimally in different situations. This flexible and reliable adjustment method is suitable for a variety of applications requiring adjustment of the spoiler 122 angle.

[0110] In an alternative embodiment, the angle of the spoiler 122 can be adjusted using a rotating shaft, screw, or gear transmission. For example, by providing a rotating shaft between the mounting plate 124 and the spoiler 122, the spoiler 122 can be rotated about the axis of the rotating shaft, thereby changing the tilt angle of the spoiler 122. This design allows for continuous and smooth adjustment of the angle of the spoiler 122, making adjustment more convenient and precise. Alternatively, the angle of the spoiler 122 can be adjusted using a screw transmission mechanism. By rotating the screw, the spoiler 122 can be moved up and down or rotated, thereby changing its tilt angle. This transmission method is simple and reliable, making it suitable for applications requiring precise angle control. Gear transmission is also a common method, enabling the angle of the spoiler 122 to be adjusted through the meshing rotation of gears. Gear transmission offers a simple, stable structure with high transmission efficiency, making it suitable for applications requiring high precision in the angle adjustment of the spoiler 122. Those skilled in the art can select an appropriate adjustment method based on actual needs.

[0111] According to one embodiment of the present invention, referring to Figure 5 As shown, the first adjusting screw 152 and the second adjusting screw 153 are symmetrically arranged about the middle portion of the spoiler 122 .

[0112] It is understood that in this embodiment, the first adjustment screw 152 and the second adjustment screw 153 are symmetrically arranged about the middle of the spoiler 122. This arrangement ensures that the height changes on the left and right sides of the spoiler 122 are symmetrical during the adjustment process, thereby making the angle adjustment of the spoiler 122 more uniform and stable.

[0113] By symmetrically positioning the first and second adjustment screws 153 in the middle of the spoiler 122, changes in the depth of the adjustment screws simultaneously affect the heights of both the left and right sides of the spoiler 122, maintaining the balance of the spoiler 122 during adjustment. This ensures that the spoiler 122 remains stable during angle adjustment, preventing tilting or unevenness.

[0114] The symmetrical arrangement of the first and second adjustment screws 153 also helps to simplify the adjustment operation, making it easier for the user to accurately adjust the angle of the spoiler 122. At the same time, the symmetrical arrangement can also improve the stability and reliability of the system, ensuring that the spoiler 122 can maintain good performance under various working conditions.

[0115] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, there are multiple spoiler jets 1201, and the spoiler jets 1201 in two adjacent rows are staggered.

[0116] It is understandable that, in the present embodiment, spoiler 122 can be provided with multiple rows of spoiler wave nozzles 1201, and the spoiler wave nozzles 1201 of two adjacent rows are staggered. By arranging multiple spoiler wave nozzles 1201, the entire circuit board surface can be covered, ensuring that each area is sufficiently disturbed and coated, thereby avoiding the problem of soldering leaks. The staggered arrangement of spoiler wave can increase the disturbance range, ensuring that the entire circuit board surface is uniformly covered, and the arrangement of multiple spoiler wave nozzles 1201 can increase the turbulence degree of fluid, which helps to improve the uniformity and coverage of coating, and reduces the risk of soldering leaks. The turbulence effect can also ensure that the coating material forms a uniform coating on the circuit board surface, improves the quality and reliability of welding, and through comprehensive coverage and enhanced turbulence effect, spoiler wave can effectively reduce the risk of soldering leaks in the circuit board, and solder can evenly cover the entire circuit board surface, ensuring that soldering points are fully covered and welded, and improves the success rate of welding.

[0117] According to one embodiment of the present invention, referring to Figure 1 and Figure 2As shown, a nozzle 1202 is provided on the side of the spoiler wave nozzle 1201 facing the circuit board to be soldered.

[0118] It is understood that in this embodiment, by providing nozzle 1202 within spoiler wave nozzle 1201, the solder spraying force can be increased, ensuring that the coating is sprayed onto the circuit board at a higher speed and pressure. This helps the coating more evenly cover the soldering area, reducing the risk of missed coating and uneven coating. The provision of nozzle 1202 can limit the coating's dispersion range, allowing it to more concentratedly cover the target area, preventing excessive coating diffusion during the spraying process, ensuring effective coverage of the soldering area, reducing the risk of missed coating, and improving soldering quality.

[0119] In the related art, in the production process of circuit boards for home appliances, wave soldering of high-power devices is performed by using a combination of disturbed waves and smooth waves to achieve soldering of the mainboard. However, during this type of soldering, some undesirable phenomena are prone to occur, such as cold soldering, excessive soldering, solder bridges, and insufficient soldering height.

[0120] According to one embodiment of the present invention, referring to Figure 1 As shown, the wave soldering nozzle structure 10 includes a base 110, a smooth wave generating component 130 and a height adjustment component 160. The base 110 is formed with a guide cavity. The smooth wave generating component 130 is arranged on the base 110, and the smooth wave generating component 130 is connected to the guide cavity. The height adjustment component 160 is arranged on the smooth wave generating component 130, and the height adjustment component 160 is used to adjust the height of the smooth wave generating component 130 relative to the base 110.

[0121] The flat wave generating assembly 130 is used to generate flat waves, which enable the solder to evenly cover the welding area, and control the temperature distribution of the material in the welding area through stable solder flow, thereby improving welding quality.

[0122] It is understood that in this embodiment, by providing a height adjustment member 160, the height of the flat wave generating assembly 130 relative to the base 110 can be adjusted, thereby adjusting the height of the flat wave. This design allows for precise control of the flat wave height, thereby adjusting the amount of tin in the solder joints and reducing the occurrence of poor solder joints and solder bridges. Furthermore, this design is adaptable to different types of workpieces, improving the versatility and flexibility of the device.

[0123] By adjusting the height of the flat wave, you can ensure that the solder evenly covers the weld area during the soldering process. This can be adjusted based on the specific characteristics of the workpiece to achieve the optimal soldering result. This helps control the amount of solder in the solder joint, avoiding excessive or insufficient solder, thereby reducing defects such as continuous soldering and solder bridges. It can also be adapted to different welding conditions requiring adjustable flat wave height and to different workpiece types, increasing the flexibility and applicability of the welding process, thereby improving welding quality and production efficiency.

[0124] According to one embodiment of the present invention, referring to Figure 1 and Figure 6 As shown, the advection wave generating assembly 130 includes a middle baffle 123 and a rear baffle 132 that are relatively arranged, and a flat plate 131, one side of the flat plate 131 is connected to the middle baffle 123, and the other side is connected to the rear baffle 132, wherein the middle baffle 123, the flat plate 131 and the rear baffle 132 form a flat flow cavity, and the height adjustment member 160 is used to adjust the height of the rear baffle 132.

[0125] It is understandable that, in this embodiment, the height adjustment member 160 is generally used to adjust the height of the rear baffle 132 , thereby affecting the formation and flow of the entire advection wave.

[0126] By adjusting the height of the rear baffle 132, the shape and size of the advection chamber can be altered, thereby adjusting the formation and height of the advection wave. This design allows the parameters of the advection wave to be adjusted according to specific welding needs and workpiece requirements to achieve optimal welding results. Adjusting the height of the rear baffle 132 can influence the flow of solder during the welding process, helping to control the amount and uniformity of solder applied, thereby reducing the occurrence of welding defects.

[0127] In general, by adjusting the height of the rear baffle 132 through the height adjustment member 160, the formation and flow of the flat wave can be affected, thereby controlling the distribution and quality of the solder during the welding process and improving the stability and efficiency of welding. By adjusting the height of the rear baffle 132, the height of the flat wave can be precisely controlled according to specific welding requirements and workpiece requirements, reducing the generation of tin slag, which helps to ensure that the solder can evenly cover the welding area and avoid too much or too little solder.

[0128] According to one embodiment of the present invention, referring to Figure 1 and Figure 3 As shown, the advection plate 131 is provided with side plates 133 on both sides of its length direction, and the height of the side plates 133 is adjustable.

[0129] It will be appreciated that in this embodiment, the middle baffle 123, rear baffle 132, flat plate 131, and side plates 133 on either side collectively enclose a flat flow chamber for generating flat flow waves. The height of the rear baffle 132 is adjustable to adjust the height of the flat flow waves. Simultaneously, the heights of the side plates 133 on either side can also be adaptively adjusted to follow the height of the rear baffle 132. The heights of the side plates 133 can be adjusted based on specific welding requirements and workpiece shape to ensure that the flow direction and velocity of the airflow within the welding area meet the requirements. This allows the solder to flow and spread evenly during the welding process, reducing the occurrence of welding defects and improving welding quality.

[0130] It should be noted that the height of the side panel 133 may be flush with the height of the rear baffle 132 , or may be slightly lower than the height of the rear baffle 132 , which is not specifically limited in this embodiment.

[0131] According to one embodiment of the present invention, referring to Figure 1 and Figure 6 As shown, the height adjustment member 160 includes a second adjustment long hole 161 and a second positioning bolt 162. The second adjustment long hole 161 is provided on the rear baffle 132. The second adjustment long hole 161 extends along the height direction of the flat plate 131. For example, the second adjustment long hole 161 extends obliquely upward along the height direction of the flat plate 131. The second positioning bolt 162 is suitable for passing through the second adjustment long hole 161 and being connected to the flat plate 131 to fix the height of the rear baffle 132.

[0132] It will be appreciated that in this embodiment, when the height of the rear baffle 132 needs to be changed, it is only necessary to loosen the second positioning bolt 162, move the second adjustment slot 161 to the desired position, and then tighten the second positioning bolt 162 to fix the height of the rear baffle 132. The cooperation between the second positioning bolt 162 and the second adjustment slot 161 allows the height of the rear baffle 132 to be easily adjusted to meet different welding requirements and workpiece characteristics. Furthermore, the height of the flattened wave can be effectively controlled, thereby improving welding quality and efficiency.

[0133] In an optional embodiment, a mounting hole is formed in the flat plate 131, and a second positioning bolt 162 can be passed through the second adjustment slot 161 and the mounting hole to attach the rear baffle 132 to the flat plate 131. By adjusting the position of the second adjustment slot 161 to connect with the mounting plate 124, the height of the rear baffle 132 can be flexibly changed, thereby adjusting the airflow and heat transfer within the welding area to meet the requirements of different welding situations.

[0134] This design is simple and effective, making the installation and height adjustment of the rear baffle 132 convenient and flexible. Through reasonable adjustment, the connection between the rear baffle 132 and the flat plate 131 can be ensured to be firm and stable, while also achieving precise control of airflow and heat during welding, thereby improving welding efficiency and quality.

[0135] In other embodiments, the height adjustment member 160 may employ various types of adjustment structures, as long as they enable flexible height adjustment. In addition to the second adjustment slot 161 and the second positioning bolt 162, various mechanical structures such as screws, nuts, adjustment bolts, sliders, cams, and even hydraulic or pneumatic adjustment systems may also be used to achieve height adjustment in the welding equipment. This application does not impose any specific limitations on any such mechanism, as long as it enables adjustment of the height of the rear baffle 132.

[0136] These adjustment structures can be selected based on specific design requirements and application scenarios to better adapt to different welding equipment and process requirements. By properly selecting and configuring the height adjustment member 160, the height of various components in the welding equipment can be adjusted, thereby meeting the precise control of welding parameters in different welding situations and improving welding quality and efficiency.

[0137] According to one embodiment of the present invention, referring to Figure 1 and Figure 6 As shown, there are multiple second adjustment long holes 161 , and the multiple second adjustment long holes 161 are spaced apart along the length direction of the rear baffle 132 .

[0138] It will be appreciated that in this embodiment, by providing multiple second adjustment slots 161 on the rear baffle 132, more adjustment options and flexibility are provided. Each second adjustment slot 161 can be used with a corresponding positioning bolt to fix the distance between the middle baffle 123 and the rear baffle 132. Furthermore, the multiple second adjustment slots 161 are spaced apart along the length of the rear baffle 132. This ensures that the height adjustment of the rear baffle 132 remains consistent at all locations, ensuring a consistent advection wave height at all locations, and ensuring stability and consistency during the welding process.

[0139] According to an embodiment of the present invention, the second adjustment slot 161 is further provided with a scale line (not shown in the figure), and the scale line is used to indicate the adjustment height of the rear baffle 132 .

[0140] In an optional embodiment, scale indicator lines are provided around the second adjustment slot 161 , and the scale indicator lines can facilitate the user in determining the height of the rear baffle 132 , thereby improving the adjustment accuracy of the height of the rear baffle 132 .

[0141] The graduated indicator lines allow the operator to intuitively read the adjustment distance, eliminating the need for additional measurements and reducing the possibility of inaccurate adjustments due to errors. This design significantly simplifies the operating process, improves work efficiency, and ensures accurate height adjustment during welding. The graduated indicator lines make height adjustment of the rear baffle 132 more intuitive and convenient, significantly improving work efficiency when frequent adjustments to the advection wave height are required.

[0142] According to one embodiment of the present invention, referring to Figure 1 、 Figure 2 and Figure 4 As shown, the middle baffle 123 is provided with a first folded edge 1231 , the first folded edge 1231 abuts against the flat plate 131 , and the first folded edge 1231 and the flat plate 131 are suitable for relative sliding to adjust the distance between the middle baffle 123 and the rear baffle 132 .

[0143] It will be appreciated that, in this embodiment, when the advection plate 131 is adjusted to increase the distance between the rear baffle 132 and the middle baffle 123, the width of the advection wave will also increase accordingly. Conversely, when the advection plate 131 is adjusted to decrease the distance between the rear baffle 132 and the middle baffle 123, the width of the advection wave will also decrease. By adjusting the distance between the middle baffle 123 and the rear baffle 132, the width of the advection wave can be flexibly controlled to meet specific welding requirements and workpiece characteristics. In actual operation, the distance adjustment member 140 needs to be appropriately adjusted according to the needs of the welding process and the desired effect to obtain the optimal advection wave width.

[0144] During welding, adjusting the width of the flat wave can affect welding speed and heat input. A narrow flat wave results in faster welding speeds and relatively lower heat input, while a wider flat wave slows welding speeds and increases heat input. Adjusting the flat wave width allows for better control of welding speed and heat input, thereby affecting weld formation and quality. A narrow flat wave results in a narrower weld, a higher weld height, and a sharper weld appearance, while a wider flat wave results in a wider weld, a lower weld height, and a flatter weld appearance. Appropriately adjusting the flat wave width can achieve more desirable weld appearance and quality. In practice, operators can adjust the flat wave width based on specific welding requirements and workpiece characteristics to achieve optimal welding results.

[0145] In an optional embodiment, the smooth wave generating assembly 130 is further provided with a first positioning bolt 142, and a first adjustment long hole 141 is opened in one of the first folded edge 1231 and the smooth flow plate 131. The first adjustment long hole 141 extends along the width direction of the smooth wave generating assembly 130, and the first positioning bolt 142 is suitable for passing through the first adjustment long hole 141 to connect the first folded edge 1231 and the smooth flow plate 131, and fix the distance between the middle baffle 123 and the rear baffle 132.

[0146] According to one embodiment of the present invention, referring to Figure 1 As shown, the wave soldering nozzle structure 10 also includes a turbulent wave generating assembly 120 arranged side by side with the flat wave generating assembly 130. The turbulent wave generating assembly 120 is provided with a turbulent wave nozzle 1201, which is connected to the guide cavity and is used to generate turbulent waves. The design of the turbulent wave generating assembly 120 can introduce turbulent waves at the same time as the flat wave is generated, thereby better promoting heat and mass transfer during the welding process, and realizing the simultaneous operation and mutual cooperation of the turbulent waves and the flat wave.

[0147] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the flat wave generating assembly 130 is provided with a distance adjusting member 140 , and the distance adjusting member 140 is used to adjust the distance between the rear baffle 132 and the middle baffle 123 .

[0148] It will be appreciated that in this embodiment, the distance between the rear baffle 132 and the middle baffle 123 is adjusted by providing a distance adjustment member 140, thereby adjusting the width of the flat wave generated by the flat wave generating assembly 130. When the distance adjustment member 140 is adjusted to increase the distance between the rear baffle 132 and the middle baffle 123, the width of the flat wave is also increased accordingly. Conversely, when the distance adjustment member 140 is adjusted to decrease the distance between the rear baffle 132 and the middle baffle 123, the width of the flat wave is also decreased. By adjusting the distance adjustment member 140, the width of the flat wave can be flexibly controlled to meet specific welding requirements and workpiece characteristics. In actual operation, the distance adjustment member 140 needs to be appropriately adjusted according to the needs of the welding process and the desired effect to obtain the optimal flat wave width.

[0149] During welding, adjusting the width of the flat wave can affect welding speed and heat input. A narrow flat wave results in faster welding speeds and relatively lower heat input, while a wider flat wave slows welding speeds and increases heat input. Adjusting the flat wave width allows for better control of welding speed and heat input, thereby affecting weld formation and quality. A narrow flat wave results in a narrower weld, a higher weld height, and a sharper weld appearance, while a wider flat wave results in a wider weld, a lower weld height, and a flatter weld appearance. Appropriately adjusting the flat wave width can achieve more desirable weld appearance and quality. In practice, operators can adjust the flat wave width based on specific welding requirements and workpiece characteristics to achieve optimal welding results.

[0150] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the distance adjustment member 140 includes a first adjustment long hole 141 and a first positioning bolt 142. The first adjustment long hole 141 is provided on the advection plate 131 or the middle baffle 123. The first adjustment long hole 141 extends along the width direction of the advection plate 131. The first positioning bolt 142 is suitable for passing through the first adjustment long hole 141 and connecting the middle baffle 123 and the advection plate 131 to fix the distance between the middle baffle 123 and the rear baffle 132.

[0151] It can be understood that in this embodiment, since the rear baffle 132 is installed on the flat plate 131, the distance between the middle baffle 123 and the rear baffle 132 can be adjusted by adjusting the relative position of the flat plate 131 and the middle baffle 123, thereby adjusting the width of the flat wave to meet the requirements of the welding process.

[0152] In this embodiment, the first positioning bolt 142 is used as the main component of the distance adjustment member 140. The first positioning bolt 142 is a threaded connection member whose length is suitable for passing through the first adjustment long hole 141 and connecting the middle baffle 123 and the flat plate 131 to fix the distance between the middle baffle 123 and the rear baffle 132.

[0153] To adjust the width of the flattened wave, simply loosen the first positioning bolt 142, move the first adjustment slot 141 to the desired position, and then tighten the first positioning bolt 142 to fix the distance between the rear baffle 132 and the middle baffle 123. The coordination of the first positioning bolt 142 and the first adjustment slot 141 allows for easy adjustment of the distance between the rear baffle 132 and the middle baffle 123 to meet varying welding requirements and workpiece characteristics. Distance adjuster 140 also effectively controls the width of the flattened wave, improving welding quality and efficiency.

[0154] According to one embodiment of the present invention, referring to Figure 1and Figure 2 As shown, there are multiple first adjustment long holes 141 , and the multiple first adjustment long holes 141 are arranged at intervals along the length direction of the flattening plate 131 .

[0155] It will be appreciated that in this embodiment, by providing multiple first adjustment slots 141 on the advection plate 131, more adjustment options and flexibility are provided. Each first adjustment slot 141 can be used with a corresponding positioning bolt to fix the distance between the middle baffle 123 and the rear baffle 132. Furthermore, the multiple first adjustment slots 141 are spaced apart along the length of the advection plate 131. This ensures that the distance adjustment at all locations on the advection plate 131 remains consistent, ensuring that the middle baffle 123 and the rear baffle 132 remain parallel during adjustment, and ensuring stability and consistency during the welding process.

[0156] In an optional embodiment, scale indicator lines are provided around the first adjustment slot 141 , and the scale indicator lines can facilitate the user in determining the adjustment distance between the middle baffle 123 and the rear baffle 132 , thereby improving the adjustment accuracy.

[0157] The graduated indicator lines allow operators to intuitively read the adjustment distance, eliminating the need for additional measurements and reducing the possibility of inaccurate adjustments due to errors. This design significantly simplifies the operating process, improves work efficiency, and ensures accurate distance adjustment during welding. The graduated indicator lines make distance adjustment between the middle baffle 123 and the rear baffle 132 more intuitive and convenient, significantly improving work efficiency when frequent adjustments to the advection wave width are required.

[0158] The embodiment of the second aspect of the present utility model, referring to Figure 8 As shown, a wave soldering device is provided, including a tin furnace 400, a driving device 20 and a wave soldering nozzle structure 10 of any one of the above embodiments, the tin furnace 400 is formed with a tin cavity, the wave soldering nozzle structure 10 is arranged in the tin furnace 400, and the driving device 20 connects the tin cavity and the wave soldering nozzle structure 10.

[0159] In this embodiment, the solder pot 400 is a device for melting soldering material (such as tin or other solder). It has a tin chamber for containing and heating the soldering material. A drive device 20 is used to control the flow and ejection of the soldering material. The drive device 20 connects the tin chamber and the wave soldering nozzle structure 10. The drive device 20, via a pump or other drive mechanism, transports the molten soldering material from the tin chamber to the wave soldering nozzle structure 10. The wave soldering nozzle structure 10 is disposed within the tin pot 400 and is connected to the drive device 20. The wave soldering nozzle structure 10 generates flat and turbulent waves to solder circuit boards.

[0160] The entire device works as follows: the drive device 20 extracts or pushes the molten solder material from the tin cavity into the wave soldering nozzle structure 10. The nozzle structure generates flat and turbulent waves based on the design principle. These waves help improve the quality and efficiency of soldering. The solder material is ejected through the wave soldering nozzle structure 10 to the soldering area, completing the soldering process of the circuit board and electronic components.

[0161] In related technologies, the wave soldering nozzle structure 10 can generate turbulent waves and horizontal waves to solder circuit boards. In order to reduce the generation of tin slag, the wave soldering nozzle is generally placed in a tin furnace 400. During operation, the temperature of the tin furnace 400 is relatively high, and the height of the horizontal wave is inconvenient to adjust, which can easily lead to unstable welding quality and affect welding efficiency.

[0162] According to one embodiment of the present invention, referring to Figure 1 and Figure 7 As shown, the wave soldering equipment includes a tin furnace 400, a wave soldering nozzle structure 10 and a height adjustment member 160, the tin furnace 400 forms a tin cavity; the wave soldering nozzle structure 10 is arranged in the tin cavity, the wave soldering nozzle structure 10 includes a base 110 and a flat wave generating assembly 130 arranged on the base 110; the height adjustment member 160 includes an operating part 163 and a transmission part 164, the operating part 163 is connected to the flat wave generating assembly 130 through the transmission part 164 to adjust the height of the flat wave generating assembly 130, and the operating part 163 is at least partially arranged outside the tin cavity.

[0163] It is understood that in this embodiment, the height adjustment member 160 includes an operating portion 163 and a transmission portion 164. The operating portion 163 and the transmission portion 164 are used to adjust the height of the flat wave generating assembly 130, thereby adjusting the height of the flat wave, thereby adjusting the amount of tin in the tin spot and reducing the occurrence of poor solder joints and bridging, thereby improving welding quality. The operating portion 163 is disposed outside the tin pot 400, and the operator can directly adjust the height through the operating portion 163 without having to open the tin pot 400 or move the equipment, making the operation more convenient and quick. Since the operating portion 163 is at least partially disposed outside the tin pot 400, the operator's chance of contact with high-temperature equipment can be reduced, reducing operational risks and improving work safety. The height of the flat wave generating assembly 130 can be precisely controlled by the transmission portion 164, achieving precise adjustment of the flat wave height, thereby improving welding quality and production efficiency. By adjusting the height of the flat wave outside the tin pot 400, it can be flexibly adjusted according to different welding requirements and workpiece characteristics, meeting different welding needs, and being applicable to different types of workpieces, thereby improving the versatility and flexibility of the equipment.

[0164] According to one embodiment of the present invention, referring to Figure 7As shown, the flat wave generating assembly 130 includes a middle baffle 123 and a rear baffle 132 that are relatively arranged, as well as a flat plate 131. The transmission part 164 is connected to the rear baffle 132 to adjust the height of the rear baffle 132. The flat plate 131 connects the middle baffle 123 and the rear baffle 132. A flat flow cavity is formed between the middle baffle 123, the flat plate 131 and the rear baffle 132 for generating flat waves.

[0165] It will be appreciated that in this embodiment, the connection between the transmission unit 164 and the rear baffle 132 allows precise adjustment of the height of the rear baffle 132 by controlling the movement of the transmission unit 164, thereby achieving precise adjustment of the height of the flat wave. The connection structure of the transmission unit 164 for adjusting the height of the rear baffle 132 is well designed and relatively simple to operate, allowing the operator to easily adjust the height, thereby improving production efficiency. By adjusting the height of the flat wave, the device can be adapted to different welding requirements and workpiece specifications, making it more adaptable and flexible in different scenarios. By precisely adjusting the height of the flat wave, the shape and height of the wave crest during the welding process can be controlled, thereby ensuring welding quality and stability.

[0166] It should be noted that the structure of the transmission part 164 may include but is not limited to gears, screw rods, chains, hydraulic cylinders, etc., so as to achieve precise adjustment of the height of the tailgate 132.

[0167] In an alternative embodiment, the transmission portion 164 utilizes a gear transmission. Gear transmission transmits motion and force through the intermeshing of gears, enabling more precise height adjustment. By adjusting the size and ratio of the gear teeth, the height of the tailgate 132 can be finely adjusted, which is suitable for applications requiring higher precision.

[0168] In another optional embodiment, the transmission portion 164 uses a screw drive. The screw drive utilizes the helical interaction of the nut and the screw to convert rotational motion into linear displacement, thereby achieving precise adjustment of the height of the rear baffle 132. The screw drive has high transmission efficiency and accuracy and is suitable for applications requiring precise adjustment.

[0169] In another optional embodiment, the transmission part 164 adopts hydraulic transmission, which realizes motion control by transmitting pressure through the hydraulic system. The height of the tailgate 132 can be precisely adjusted by precisely controlling the movement of the hydraulic cylinder. It is suitable for large equipment and occasions requiring high-power transmission.

[0170] In another optional embodiment, the transmission part 164 adopts chain transmission. The chain transmission uses the cooperation of the chain and gears to transmit motion and force, which can achieve relatively stable and reliable transmission and adjust the height of the tailgate 132.

[0171] In this embodiment, the operating portion 163 can be designed as a handle, knob, or other structure. In one optional embodiment, rotating or pushing or pulling the handle controls the displacement of the transmission portion 164, thereby adjusting the height of the rear baffle 132. The handle is simple and intuitive to operate, making it suitable for applications where frequent height adjustment of the rear baffle 132 is required. In another optional embodiment, the transmission portion 164 can be controlled by rotating the knob, thereby adjusting the height of the rear baffle 132. The knob's design offers flexibility and can be used in conjunction with scale lines, making it suitable for applications requiring precise adjustment.

[0172] According to one embodiment of the present invention, referring to Figure 6 and Figure 7 As shown, the transmission part 164 includes a transmission screw and a nut movably arranged on the transmission screw. One end of the transmission screw is connected to the operating part 163, and the other end is connected to the rear baffle 132 through the nut.

[0173] It is understood that in this embodiment, the operator can rotate the operating portion 163 (e.g., a handle, knob, etc.) to drive the transmission portion 164 to move. When the operating portion 163 rotates, the transmission screw slides up and down along the guide slot 134. The movement of the transmission screw drives the movement of the nut engaged therewith, thereby causing the rear baffle 132 to move in the up and down direction, thereby adjusting the height of the rear baffle 132.

[0174] As needed, the operator can gradually rotate or push and pull the operating portion 163 to fine-tune the height of the rear baffle 132 until the desired height is met without using complex tools or performing tedious operations. The advantage of this adjustment method is that it is easy to operate and can achieve high precision by adjusting the height of the rear baffle 132 through the drive screw.

[0175] According to one embodiment of the present invention, the rear baffle 132 is provided with a guide slot 134, into which the nut slides. This helps ensure that the nut maintains the correct orientation and position during movement. The guide slot 134 effectively guides the nut's movement, preventing it from deviating during movement. Furthermore, the presence of the guide slot 134 ensures the relative stability of the nut during movement, preventing the rear baffle 132 from tilting or shaking during height adjustment, thereby ensuring the stability of the rear baffle 132 during height adjustment.

[0176] According to one embodiment of the present invention, the guide slot 134 is provided along the vertical direction of the rear baffle 132. By providing the guide slot 134 along the vertical direction, the movement of the nut is directly linked to the vertical movement of the rear baffle 132, allowing the operator to more directly control the height adjustment of the rear baffle 132. Because the guide slot 134 limits the movement direction of the nut, the vertical movement of the rear baffle 132 can be more precisely controlled, making the height adjustment more accurate.

[0177] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 The wave soldering nozzle structure 10 further includes a tin slag collecting trough 170 , which is disposed on a side of the rear baffle 132 away from the middle baffle 123 .

[0178] It will be appreciated that in this embodiment, by providing a slag collection trough 170 on one side of the rear baffle 132, slag generated during the wave soldering process can be collected, facilitating slag cleaning. Slag, a byproduct of the wave soldering process, can deposit on soldering equipment components, causing contamination and clogging, and even affecting soldering quality. Therefore, providing a slag collection trough 170 helps avoid these issues and improve equipment reliability and service life.

[0179] By positioning the slag collection trough 170 on the side of the rear baffle 132 away from the middle baffle 123, it can be relatively isolated from the welding area, reducing interference of slag on the welding process and the possibility of slag falling back into the solder pot 400, thereby reducing contamination of the solder in the solder pot 400. After welding, the operator can easily clean the slag collection trough 170, keeping the equipment clean and in good working condition, which helps improve the stability and maintainability of the wave soldering equipment and has a good effect on ensuring welding quality and normal operation of the equipment.

[0180] According to one embodiment of the present invention, referring to Figure 7 As shown, the tin slag collecting trough 170 is disposed above the tin cavity, and the tin slag collecting trough 170 is provided with a through hole 171 communicating with the tin cavity.

[0181] It is understood that in this embodiment, during the wave soldering process of the wave soldering equipment, the solder ejected from the flat wave nozzle 1301 forms a solder wave and flows along the soldering area. Some of the solder may splash or fall into the slag collection tank 170. By providing a through hole 171 connected to the tin chamber, the solder can flow from the through hole 171 of the slag collection tank 170 back into the tin chamber, achieving a solder recirculation cycle, maintaining a stable solder supply in the tin chamber, and ensuring consistent and stable soldering quality.

[0182] In an optional embodiment, the through hole 171 is opened at the bottom of the tin slag collecting trough 170, which facilitates the reflux circulation of the solder; in another optional embodiment, the through hole 171 can also be opened on the side of the tin slag collecting trough 170, and at a certain height from the bottom of the tin slag collecting trough 170. By setting a certain height, the possibility of tin slag falling from the through hole 171 into the tin furnace 400 can be reduced.

[0183] According to one embodiment of the present invention, referring to Figure 2 and Figure 7 As shown, there are multiple through holes 171 , and the multiple through holes 171 are spaced apart along the length direction and / or width direction of the tin slag collecting trough 170 .

[0184] It can be understood that in this embodiment, by providing a plurality of through holes 171 arranged at intervals, the reflux and recycling of the solder can be effectively promoted. By reasonably providing a plurality of through holes 171, a more uniform reflux distribution of the solder can be achieved, thereby improving the reflux efficiency.

[0185] In an optional embodiment, the size and number of the through holes 171 need to be reasonably designed according to the specific welding parameters and equipment characteristics. The through holes 171 can be evenly distributed in the length and width directions of the tin slag collection trough 170 to ensure that the reflux of the solder is evenly distributed to avoid local accumulation or excessive flow.

[0186] According to one embodiment of the present invention, referring to Figure 2 As shown, the tin slag collecting trough 170 has a first side 172 and a second side 173 . The height of the first side 172 is lower than that of the second side 173 , and the first side 172 is provided with a through hole 171 .

[0187] It can be understood that in this embodiment, the tin slag collection trough 170 is tilted so that the height of the first side 172 is lower than the height of the second side 173, and a through hole 171 is provided on the first side 172. By setting the through hole 171 at a lower position on the first side 172, the solder can flow naturally along the tilted direction more easily, and due to the effect of gravity, it can flow back more smoothly through the through hole 171. This design can improve the efficiency of solder reflux.

[0188] In this embodiment, the first side 172 and the second side 173 can be opposite sides of the slag collecting trough 170 along the length direction, or can be opposite sides of the slag collecting trough 170 along the width direction. Setting the first side 172 lower along the length direction of the slag collecting trough 170 can promote the natural flow of the solder to the through hole 171 and smoothly flow back into the tin pot 400. Similarly, setting the first side 172 lower along the width direction of the slag collecting trough 170 can also achieve smooth solder backflow, which is not specifically limited in this embodiment.

[0189] For example, in an optional embodiment, the height of the tin slag collecting trough 170 close to the smooth wave generating assembly 130 is lower than the height away from the smooth wave generating assembly 130, and the through hole 171 is provided at the end of the tin slag collecting trough 170 close to the smooth wave generating assembly 130.

[0190] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the wave soldering nozzle structure 10 also includes a spoiler wave generating component 120 arranged side by side with the flat wave generating component 130, the base 110 is formed with a guide cavity, the spoiler wave generating component 120 is provided with a spoiler wave nozzle 1201, and the flat wave generating component 130 is provided with a flat wave nozzle 1301, and the spoiler wave nozzle 1201 and the flat wave nozzle 1301 are both connected to the guide cavity.

[0191] In this embodiment, the turbulent wave nozzle 1201 and the flat wave nozzle 1301 are both connected to the guide cavity. The turbulent wave nozzle 1201 and the flat wave nozzle 1301 can be welded by only one driving motor to transport the solder into the guide cavity, which simplifies the operation steps, reduces the operation complexity, and thus improves work efficiency. In addition, only one driving motor is needed to transport the solder during the entire welding process. Compared with the traditional two motors that drive the turbulent wave generating component 120 and the flat wave generating component 130 respectively, energy consumption is reduced and production costs are reduced.

[0192] It can be understood that the wave soldering nozzle structure 10 has the beneficial effects of the above embodiments, and the wave soldering equipment correspondingly has the beneficial effects of the above embodiments. Its specific implementation method can refer to the above embodiments, and this application will not elaborate on it.

[0193] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be covered by the scope of protection of the present invention.
