[0040] The embodiments of the present utility model refer to Figure 1-Figure 8 As shown, a wave soldering nozzle structure 10 and a wave soldering device are provided.

[0041] 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 driven separately by turbulence pumps and horizontal pumps respectively. The turbulence pump drives the tin liquid in the tin furnace 400 to eject from the turbulence wave nozzle 1201 to form turbulence waves. The turbulence wave nozzle 1201 generates rotating airflow and eddy current by designing a specific shape and aperture, thereby disturbing the gas flow and heat distribution in the welding area; the horizontal flow pump drives the tin liquid in the tin furnace 400 to eject from the horizontal wave nozzle to form horizontal waves. The horizontal wave nozzle 1301 maintains the temperature of the welding area and the stability of the gas flow by designing a specific shape and aperture, thereby achieving uniform heat distribution.

[0042] According to an embodiment of the present utility model, please refer to Figure 1 and Figure 2According to the wave soldering nozzle structure 10 of the embodiment of the utility model, it includes a base 110, a spoiler wave generating component 120 and a flat wave generating component 130. The base 110 is formed with a guide cavity, and the guide cavity is suitable for communicating with the tin furnace through a driving device. The spoiler wave generating component 120 and the flat 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 flat wave generating component 130 is provided with a flat wave nozzle 1301. The spoiler wave nozzle 1201 and the flat wave nozzle 1301 are both connected with the guide cavity.

[0043] 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 spoiler wave nozzle 1201 and the flat wave nozzle 1301 respectively to form spoiler waves and flat waves. The wave soldering nozzle structure 10 of this embodiment integrates the spoiler wave generating component 120 and the flat wave generating component 130 on the same base 110, realizing the integration of spoiler waves and flat waves, that is, the spoiler wave component and the flat wave component can work at the same time.

[0044] The spoiler wave nozzle 1201 is a component on the spoiler wave generating assembly 120, through which the tin liquid can be sprayed to the welding area and a spoiler wave can be generated, thereby enhancing the mixing degree of the tin liquid and improving the welding quality. The spoiler wave nozzle 1201 is usually designed to be a plurality of small holes or slits, so that the tin liquid can be dispersed into a plurality of small streams to generate spoiler waves. The spoiler wave nozzle 1201 can also adjust the angle and effect of the spray by changing the parameters such as the position, size and shape of the hole, so as to meet the needs of different occasions.

[0045] The advection wave nozzle 1301 is a component of the advection wave generating assembly 130, through which the tin liquid can be evenly sprayed to the welding area, maintaining the stability and fluidity of the tin liquid during the spraying process, thereby achieving the accuracy and stability of welding. The advection wave nozzle 1301 is usually designed in a long strip shape, which can make the tin liquid evenly cover the entire welding area during spraying, avoiding the violent fluctuation of the tin liquid due to inertia, and ensuring the welding quality.

[0046] 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 peaceful wave can be more conveniently achieved, thereby improving the convenience and flexibility of operation; the spoiler wave and the peaceful 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 peaceful wave generating component 130 on the same base 110 can save space and reduce the overall volume.

[0047] During the welding process, usually disturbed wave welding is performed first, which promotes 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.

[0048] It can be understood that the wave soldering nozzle structure 10 of the embodiment of the utility model includes a base 110, a spoiler wave generating component 120 and a flat wave generating component 130, the base 110 is formed with a guide cavity, the spoiler wave generating component 120 and the flat 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 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 with the guide cavity. Only one driving motor is needed to transport the solder into the guide cavity to realize the welding work of the spoiler wave nozzle 1201 and the flat wave nozzle 1301, which simplifies the operation steps, reduces the operation complexity, and thus improves the work efficiency. In the whole welding process, only one driving motor is needed to transport the solder, compared with the traditional two motors driving the spoiler wave generating component 120 and the flat wave generating component 130 respectively, which reduces the energy consumption and reduces the production cost.

[0049] Since the operation of the spoiler wave generating component 120 and the horizontal wave generating component 130 can be realized by one 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 a driving motor, one driving motor, an impeller, a frequency converter and a guide groove can be reduced, thereby greatly saving the manufacturing cost and maintenance cost of the wave soldering equipment.

[0050] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the spoiler wave generating assembly 120 and the flat wave generating assembly 130 are arranged side by side along the width direction of the base 110 .

[0051] It is understandable that, in this embodiment, the spoiler wave generating assembly 120 and the flat wave generating assembly 130 are arranged side by side in the width direction of the base 110, which can effectively utilize the space and improve the welding efficiency. At the same time, the length of the spoiler wave generating assembly 120 and the flat wave generating assembly 130 can be reduced to reduce the contact area between the tin liquid and the air during the spraying of the tin liquid by the spoiler wave nozzle and the flat wave nozzle, thereby reducing the oxidation rate of the tin slag, avoiding the generation of more tin slag, and improving the utilization rate of the solder.

[0052] In some embodiments, the spraying angles of the spoiler wave generating assembly 120 and the horizontal wave generating assembly 130 can be reasonably adjusted to ensure that the tin liquid is sprayed directly onto the welding area, thereby reducing the area of ​​contact with the air during the spraying process. Alternatively, 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, thereby reducing the time of exposure to the air. The spraying pressure and amount of the spoiler 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. Alternatively, an inert gas (such as nitrogen) can be used for protection during the welding process, thereby effectively reducing the contact between the tin liquid and the air and reducing the oxidation rate.

[0053] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the spoiler wave generating component 120 includes a front baffle 121, a spoiler 122 and a middle baffle 123 which are arranged in sequence, the spoiler 122 is provided with a spoiler wave nozzle 1201, the flat wave generating component 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 flow cavity is formed between the middle baffle 123, the flat plate 131 and the rear baffle 132.

[0054] It can be understood that in this embodiment, the spoiler wave generating assembly 120 and the advection wave generating assembly 130 are arranged closely, that is, a spoiler cavity is formed between the front baffle 121, the spoiler 122 and the middle baffle 123, and an advection cavity is formed between the middle baffle 123, the advection plate 131 and the rear baffle 132, and the spoiler cavity and the advection cavity are separated by the middle baffle 123. Such a compact structural arrangement enables the spoiler cavity and the advection cavity to play their own unique functions during the welding process, effectively control and optimize the flow state of the tin liquid, thereby improving the accuracy and stability of welding. This design helps to improve the welding quality, and can reduce the volume and realize complex operation processes in a limited space.

[0055] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the spoiler 122 and the advection plate 131 are disposed on both sides of the middle baffle 123 , and the spoiler 122 and the advection plate 131 are both in contact with the middle baffle 123 .

[0056] It can be understood that, in this embodiment, the spoiler wave generating assembly 120 and the flat wave generating assembly 130 can share the same middle baffle plate 123, and there is no interval between the spoiler wave generating assembly 120 and the flat wave generating assembly 130. By sharing the same middle baffle plate 123 and eliminating the interval between the spoiler wave generating assembly 120 and the flat wave generating assembly 130, the two assemblies can be closely combined together, reducing the additional space requirement. The overall volume of the wave soldering nozzle structure 10 can be minimized.

[0057] This compact design not only saves space occupied by the equipment, but also reduces the contact area between the solder and the air during the soldering process, reducing the risk of oxidation and contamination, thereby improving the soldering quality and efficiency. In addition, by reducing the contact area between the solder and the air, the generation rate of tin slag can also be reduced. The generation of tin slag not only affects the soldering quality, but also increases the difficulty and time of subsequent cleaning work. Therefore, reducing the generation rate of tin slag can improve the maintainability of the equipment, reduce the cost of maintenance and cleaning, improve the soldering quality of wave soldering equipment, and ensure good soldering results.

[0058] 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 advection cavity are connected.

[0059] 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.

[0060] In some embodiments, the solder is directly ejected from the advection wave nozzle 1301 through the guide cavity: in this case, the solder directly enters the advection cavity through the guide cavity, and then ejects from the advection wave nozzle 1301 to form an advection wave. This method can ensure that the solder is effectively controlled during the flow process, so that it forms a more stable and uniform advection wave, which is conducive to improving the welding quality.

[0061] In other embodiments, the solder ejected from the spoiler wave nozzle 1201 flows into the advection cavity to form a advection wave: by designing the height of the middle baffle 123 to be lower than the rear baffle 132, the solder ejected from the spoiler wave generating assembly 120 can flow into the advection cavity to a certain extent and form a advection wave with the advection plate 131. This method can also help the solder flow more evenly, reduce the generation of defects such as bubbles and oxides, and improve welding quality and stability.

[0062] In other embodiments, a part of the advection wave is formed by the solder directly ejected from the advection 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 advection cavity, which can be designed according to actual application requirements.

[0063] In this embodiment, through the connection design between the spoiler chamber and the advection chamber, the solder ejected from the spoiler wave nozzle 1201 can flow into the advection chamber to form a advection 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 can improve the welding efficiency. When the solder can flow smoothly from the spoiler chamber into the advection 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 advection 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.

[0064] 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.

[0065] 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 sprayed from the spoiler 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.

[0066] 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.

[0067] 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 wave 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.

[0068] By adjusting the height of the rear baffle 132, the height of the advection wave generated by the advection wave generating assembly 130 can be controlled, thereby affecting the atmosphere protection and solder flow in the welding area. At the same time, in order to ensure the stability and uniformity of the advection wave, the height of the middle baffle 123 also needs to be adjusted accordingly to adapt to the change in the height 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 reasonably adjusting the height of the rear baffle 132 and the middle baffle 123, more precise welding control can be achieved, and the welding quality and stability can be improved.

[0069] 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 .

[0070] It is understandable that, in the present embodiment, the width of the spoiler 122 is greater than the width of the flat plate 131, so the width of the spoiler wave is also greater than the width of the flat wave, increasing the outlet area of ​​the spoiler wave, and the larger spoiler 122 width can produce a larger spoiler wave, and provide more contact area, so that the solder is fully in contact with the circuit board to be welded. At the same time, the larger spoiler 122 width can also enhance the fluidity of the solder, and by expanding the outlet area of ​​the spoiler wave, the resistance can be reduced, so that the solder flows more smoothly during the welding process, which helps to improve the uniformity and stability of the solder during the welding process, and reduce the factors that may cause welding defects. In addition, by increasing the area of ​​the spoiler wave nozzle 1201 panel, the mixing efficiency and heat transfer speed in the welding area can be increased, which makes the welding process more efficient and can improve the welding speed.

[0071] 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, and can only be applied to welding workpieces of specific types or sizes. The application range is extremely limited, and a large amount of tin slag is generated during the welding process, affecting the welding quality.

[0072] Since the welding time cannot be adjusted, it cannot be optimized according to the requirements of different workpieces, resulting in a waste of solder. And the inability to adjust the welding time means that the equipment can only be used for welding workpieces of a certain type or size, limiting the scope of application of the equipment. For workpieces of other types or sizes, the ideal welding effect may not be obtained. Too long welding time may cause excessive tin slag to be generated, reducing the welding quality. The inability to adjust the welding time makes it difficult to control the generation of tin slag during the welding process, affecting the welding quality and appearance.

[0073] According to one embodiment of the present invention, referring to Figure 1 , Figure 4 and Figure 5As shown, the wave soldering nozzle structure 10 includes a base 110, a spoiler wave generating component 120 and an inclination adjusting 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 adjusting component 150 is arranged on the spoiler wave generating component 120, and the inclination adjusting 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.

[0074] 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 larger adjustment range, and the adjustment process is relatively simple.

[0075] The inclination adjusting member 150 may also adopt a sliding adjustment structure, that is, the angle is changed by sliding the adjusting member in a groove on the base 110. This sliding adjustment structure needs to have a certain guiding device to ensure smooth and controllable sliding.

[0076] The inclination adjustment member 150 may 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.

[0077] In addition, the inclination adjusting member 150 may also adopt an adjusting pin structure, that is, the angle is changed by inserting or pulling out the adjusting pin. This structure requires a corresponding pin groove or pin hole to fix the adjusting pin.

[0078] 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, and this embodiment does not make any specific limitation to this.

[0079] The angle of the spoiler wave can affect the welding time, that is, the welding time is positively correlated with the angle of the spoiler wave. Generally speaking, the larger the spoiler wave angle, the longer the welding time will be; the smaller the spoiler wave angle, the shorter the welding time may be. By adjusting the spoiler wave angle, the length of the welding time can be controlled to meet the welding time requirements of different workpieces. And the appropriate spoiler wave angle can effectively reduce the generation of tin slag. By adjusting the spoiler wave angle, the heat transfer and liquid flux flow during the welding process can be optimized, the generation of welding residues and tin slag can be reduced, and the welding quality and efficiency can be improved.

[0080] The angle of the spoiler wave will also affect the filling height of the liquid flux during welding. By adjusting the angle of the spoiler wave, the flow of the liquid flux during welding can be controlled, thereby affecting the filling height. This adjustment method can make the welding filling more uniform and improve the welding quality and stability.

[0081] The angle of the spoiler wave will also affect the welding effect. Different workpieces may require different welding effects, such as weld shape, welding strength, etc. By adjusting the angle of the spoiler wave, the heat distribution in the welding area and the flow of liquid flux can be changed during welding, thereby affecting the welding effect. Adjusting the angle of the spoiler wave can make the welding effect more uniform and stable to meet the workpiece's requirements for welding quality.

[0082] It can be understood that, in the present 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, and 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.

[0083] According to one embodiment of the present invention, referring to Figure 1 , Figure 2 and Figure 4 As 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 arranged on the spoiler 122.

[0084] It can be understood that, in this embodiment, by providing the spoiler wave nozzle 1201 on the spoiler plate 122 and adjusting the angle of the spoiler plate 122, the angle of the spoiler wave can be adjusted without adjusting 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.

[0085] 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 welding. The advantage of this design is that the operator can adjust the spoiler wave angle during welding by simply adjusting the angle of the spoiler 122, without the need to make complex adjustments to the entire spoiler wave generating assembly 120, which improves the convenience and efficiency of spoiler wave angle adjustment and makes the adjustment of welding parameters more intuitive and accurate.

[0086] The space between the front baffle 121, the middle baffle 123 and the spoiler 122 forms a spoiler cavity, the front baffle 121 and the middle baffle 123 are connected by the mounting plate 124, and the spoiler 122 is rotatably arranged on the mounting plate 124, which improves the structural stability of the spoiler wave generating assembly 120, reduces the looseness and swing between the components, and thus ensures the stability and consistency during the welding process. By improving the stability of the overall structure, the shape and direction of the spoiler wave during the welding process can be better controlled, thereby improving the welding quality and efficiency.

[0087] 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 .

[0088] 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.

[0089] By setting the tilt angle and height difference of the spoiler 122, the flow direction and shape of the solder during welding can be effectively controlled to improve 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.

[0090] According to one embodiment of the present invention, referring to 1 and 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.

[0091] 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 assembly 120, a spoiler wave is formed to weld the circuit board, and 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 prevent the solder from splashing when it 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.

[0092] By using the inclined setting of the guide section 1212 and the principle of fluid mechanics, the solder can be guided back to the designated position to avoid splashing and scattering, which can not only improve the safety of the welding process, but also reduce the workload of handling tin slag, and improve production efficiency and resource utilization.

[0093] 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 spoiler 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.

[0094] 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 and ensure welding quality and process stability.

[0095] 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 adjustment screw 152 and a second adjustment 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 adjustment screw 152 and the second adjustment screw 153 are arranged on both sides of the rotating member 151.

[0096] It can be understood that, in this embodiment, the spoiler 122 is rotatably mounted on the mounting plate 124 via the rotating member 151, and the rotation 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 pass through the corresponding through-holes on the spoiler 122 and abut against the mounting plate 124, and the height of the left and right sides of the spoiler 122 can be adjusted by adjusting the depth of the first adjusting screw 152 and the second adjusting screw 153 screwed into the through-holes, thereby adjusting the angle of the spoiler 122 and achieving the adjustment of the spoiler wave angle.

[0097] When the first adjustment screw 152 and the second adjustment screw 153 are rotated, they will push the spoiler 122 to change its position on the mounting plate 124, thereby changing the height difference between the left and right sides of the spoiler 122, and then adjusting the inclination angle of the spoiler 122. By controlling the depth of the two screws, the inclination angle of the spoiler 122 can be accurately adjusted to meet specific needs and requirements. This design structure is simple and effective, easy to operate, and can achieve accurate adjustment of the angle of the spoiler 122, so that the spoiler 122 can play the best effect in different occasions. This adjustment method is flexible and reliable, and is suitable for various application scenarios where the angle of the spoiler 122 needs to be adjusted.

[0098] In an optional embodiment, the angle adjustment of the spoiler 122 can also be achieved by a rotating shaft or a screw or a gear transmission. For example, by setting a rotating shaft between the mounting plate 124 and the spoiler 122, the spoiler 122 can be rotated around the axis of the rotating shaft, thereby changing the inclination angle of the spoiler 122. This design can achieve continuous and smooth adjustment of the angle of the spoiler 122, making the adjustment more convenient and accurate. In addition, the angle adjustment of the spoiler 122 can also be achieved by using a screw transmission mechanism. By rotating the screw, the spoiler 122 can be pushed up and down or rotated, thereby changing its inclination angle. This transmission method is simple and reliable, and is suitable for occasions where precise angle control is required. In addition, gear transmission is also a common method, and the angle adjustment of the spoiler 122 can be achieved by meshing and rotating the gears. The gear transmission structure is simple and stable, and the transmission efficiency is high. It is suitable for situations where the angle adjustment accuracy of the spoiler 122 is required to be high. Those skilled in the art can select a suitable adjustment method for adjustment according to actual needs.

[0099] 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 .

[0100] It is understandable 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 can ensure that the height changes of the left and right sides of the spoiler 122 are symmetrical during the adjustment process, so that the angle adjustment of the spoiler 122 is more uniform and stable.

[0101] By symmetrically arranging the first and second adjusting screws 153 in the middle of the spoiler 122, the depth change of the adjusting screws will simultaneously affect the height of the left and right sides of the spoiler 122, thereby maintaining the balance of the spoiler 122 during the adjustment process. This ensures that the spoiler 122 remains stable when adjusting the angle, and avoids tilting or unevenness.

[0102] The symmetrical arrangement of the first and second adjustment screws 153 also helps to simplify the adjustment operation, so that the user can more easily achieve accurate adjustment of 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.

[0103] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, there are multiple spoiler wave nozzles 1201, and the spoiler wave nozzles 1201 in two adjacent rows are staggered.

[0104] It is understandable that, in the present embodiment, the spoiler 122 may 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 leaking solder. The staggered arrangement of spoiler waves can increase the range of disturbance, ensuring that the entire circuit board surface is uniformly covered, and the arrangement of multiple spoiler wave nozzles 1201 can increase the turbulence of the fluid, which helps to improve the uniformity and coverage of the coating, and reduce the risk of leaking solder. 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 waves can effectively reduce the risk of leaking solder on the circuit board, and solder can evenly cover the entire circuit board surface, ensuring that the welding points are fully covered and welded, thereby improving the success rate of welding.

[0105] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, a nozzle 1202 is provided on the side of the spoiler wave nozzle 1201 facing the circuit board to be soldered.

[0106] It can be understood that, in this embodiment, by providing the nozzle 1202 at the spoiler wave nozzle 1201, the spraying force of the solder can be increased, ensuring that the coating is sprayed onto the circuit board at a higher speed and pressure. This helps the coating to cover the welding area more evenly, reducing the risk of missing coating and uneven coating. The provision of the nozzle 1202 can limit the divergence range of the coating, so that it can cover the target area more concentratedly, avoiding excessive diffusion of the coating during the spraying process, ensuring that the welding area is effectively covered, reducing the risk of missing coating, and improving welding quality.

[0107] In the related art, in the production process of home appliance circuit boards, for wave soldering of high-power devices, a combination of turbulent waves and flat waves can be used 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.

[0108] 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 flat wave generating component 130 and a height adjusting component 160. The base 110 is formed with a guide cavity. The flat wave generating component 130 is arranged on the base 110, and the flat wave generating component 130 is connected to the guide cavity. The height adjusting component 160 is arranged on the flat wave generating component 130, and the height adjusting component 160 is used to adjust the height of the flat wave generating component 130 relative to the base 110.

[0109] The advection wave generating assembly 130 is used to generate advection 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 the welding quality.

[0110] It is understandable that in this embodiment, by providing the height adjustment member 160, the height of the advection wave generating assembly 130 relative to the base 110 can be adjusted, thereby adjusting the height of the advection wave. This design allows the height of the advection wave to be accurately controlled, thereby adjusting the amount of tin in the tin spot and reducing the occurrence of poor soldering and tin bridges. At the same time, such a design can also be applied to different types of workpieces, improving the versatility and flexibility of the equipment.

[0111] By adjusting the height of the advection wave, it is possible to ensure that the solder evenly covers the welding area during the welding process, and it can be adjusted according to the specific characteristics of the workpiece to achieve the best welding effect. This helps to control the amount of tin in the tin point and avoid too much or too little solder, thereby reducing welding defects such as continuous welding and tin bridges. It can also be applied to different welding conditions that require adjustment of the height of the advection wave, suitable for different types of workpieces, and improve the flexibility and applicability of the welding process, thereby improving welding quality and production efficiency.

[0112] 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 an advection plate 131, one side of the advection 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 advection plate 131 and the rear baffle 132 form an advection cavity, and the height adjustment member 160 is used to adjust the height of the rear baffle 132.

[0113] 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.

[0114] By adjusting the height of the rear baffle 132, the shape and size of the advection cavity can be changed, 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 the best welding effect. Adjusting the height of the rear baffle 132 can affect the flow state of the solder during the welding process, help control the coating amount and uniformity of the solder, and thus reduce the occurrence of welding defects.

[0115] In general, by adjusting the height of the rear baffle 132 through the height adjustment member 160, the formation and flow of the advection 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 advection wave can be accurately controlled according to specific welding requirements and workpiece requirements, and the generation of tin slag can be reduced, which helps to ensure that the solder can evenly cover the welding area and avoid too much or too little solder.

[0116] 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.

[0117] It can be understood that in this embodiment, the middle baffle 123, the rear baffle 132, the advection plate 131 and the side plates 133 on both sides are jointly arranged to form an advection cavity for generating advection waves. The height of the rear baffle 132 can be adjusted to adjust the height of the advection wave. At the same time, the height of the side plates 133 on both sides can also be adaptively adjusted following the height of the rear baffle 132. The height of the side plates 133 can be adjusted according to specific welding requirements and workpiece shapes to ensure that the flow direction and speed of the airflow in the welding area meet the requirements. In this way, the solder can flow and apply evenly during the welding process, reduce the occurrence of welding defects, and improve the welding quality.

[0118] It should be noted that the height of the side panel 133 may be flush with the height of the rear baffle 132 , or the height of the side panel 133 may be slightly lower than the height of the rear baffle 132 , and this is not specifically limited in the present embodiment.

[0119] 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 advection plate 131. For example, the second adjustment long hole 161 extends obliquely upward along the height direction of the advection plate 131. The second positioning bolt 162 is suitable for passing through the second adjustment long hole 161 and being connected to the advection plate 131 to fix the height of the rear baffle 132.

[0120] It is understandable 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 position to be adjusted, and then tighten the second positioning bolt 162 to fix the height of the rear baffle 132. Through the cooperation of the second positioning bolt 162 and the second adjustment slot 161, the height of the rear baffle 132 can be easily adjusted to meet different welding requirements and workpiece characteristics. At the same time, the height of the advection wave can be effectively controlled to improve welding quality and efficiency.

[0121] In an optional embodiment, a mounting hole is provided on the flat plate 131, and the second positioning bolt 162 can pass through the second adjustment slot 161 and the mounting hole to achieve the installation of the rear baffle 132 on the flat plate 131. By adjusting different positions 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 flow of airflow and heat transfer in the welding area to meet the needs of different welding situations.

[0122] This design structure is simple and effective, making the installation and height adjustment of the rear baffle 132 convenient and flexible. Through reasonable adjustment, it can ensure that the connection between the rear baffle 132 and the flat plate 131 is firm and stable, and it can also achieve precise control of airflow and heat during welding, thereby improving the efficiency and quality of welding.

[0123] In other embodiments, the height adjustment member 160 may adopt various types of adjustment structures as long as the height can be flexibly adjusted. 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 be used to achieve the height adjustment function in the welding equipment. As long as the height of the rear baffle 132 can be adjusted, the present application does not make any specific restrictions on this.

[0124] These adjustment structures can be selected according to specific design requirements and application scenarios to better adapt to different welding equipment and process requirements. By reasonably selecting and configuring the height adjustment member 160, the height adjustment of various components in the welding equipment can be achieved, thereby meeting the precise control of welding parameters in different welding situations and improving welding quality and efficiency.

[0125] 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 arranged at intervals along the length direction of the rear baffle 132 .

[0126] It is understandable that in this embodiment, by providing a plurality of second adjustment slots 161 on the rear baffle 132, more adjustment options and flexibility can be provided, and each second adjustment slot 161 can use a corresponding positioning bolt to fix the distance between the middle baffle 123 and the rear baffle 132. At the same time, the plurality of second adjustment slots 161 are arranged at intervals along the length direction of the rear baffle 132, so that the height adjustment of the rear baffle 132 can be kept consistent, ensuring that the height of the advection wave at each location is kept consistent, and ensuring the stability and consistency of the welding process.

[0127] 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 .

[0128] In an optional embodiment, scale indicator lines are arranged around the second adjustment slot 161 , and the scale indicator lines can facilitate the user to determine the height of the rear baffle 132 , thereby improving the adjustment accuracy of the height of the rear baffle 132 .

[0129] Through the scale indicator line, the operator can intuitively read the adjustment distance, avoiding the trouble of additional measurement, and also reducing the possibility of inaccurate adjustment due to errors. This design can greatly simplify the operation process, improve work efficiency, and ensure the accuracy of height adjustment during welding. The setting of the scale indicator line makes the height adjustment of the rear baffle 132 more intuitive and convenient, especially when the height of the advection wave needs to be adjusted frequently, which can greatly improve work efficiency.

[0130] 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 advection plate 131 , and the first folded edge 1231 and the advection plate 131 are suitable for relative sliding to adjust the distance between the middle baffle 123 and the rear baffle 132 .

[0131] It can be understood that in this embodiment, when the advection plate 131 is adjusted so that the distance between the rear baffle 132 and the middle baffle 123 increases, the width of the advection wave will also increase accordingly. On the contrary, when the advection plate 131 is adjusted so that the distance between the rear baffle 132 and the middle baffle 123 decreases, 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, it is necessary to appropriately adjust the distance adjustment member 140 according to the needs of the welding process and the desired effect to obtain the optimal advection wave width.

[0132] During the welding process, adjusting the width of the advection wave can affect the welding speed and heat input. A narrower advection wave will result in a faster welding speed and a relatively smaller heat input; while a wider advection wave will slow down the welding speed and increase the heat input. By adjusting the width of the advection wave, the welding speed and heat input can be better controlled, thereby affecting the formation and quality of the weld; a narrower advection wave will result in a narrower weld, a higher weld height, and a sharper weld morphology; while a wider advection wave will result in a wider weld, a lower weld height, and a flatter weld morphology. Properly adjusting the width of the advection wave can obtain a weld morphology and welding quality that better meets the requirements. In actual operation, the operator can reasonably adjust the width of the advection wave according to the specific welding requirements and workpiece characteristics to achieve the best welding effect.

[0133] In an optional embodiment, the horizontal 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 horizontal flow plate 131, and the first adjustment long hole 141 extends along the width direction of the horizontal wave generating assembly 130. 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 horizontal flow plate 131, and fix the distance between the middle baffle 123 and the rear baffle 132.

[0134] According to one embodiment of the present invention, referring to Figure 1 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, and the spoiler wave generating component 120 is provided with a spoiler wave nozzle 1201, and the spoiler wave nozzle 1201 is connected to the guide cavity for generating spoiler waves. Through the design of the spoiler wave generating component 120, spoiler waves can be introduced while flat waves are formed, so as to better promote heat transfer and mass transfer in the welding process, and realize the simultaneous operation of spoiler waves and flat waves, and cooperate with each other.

[0135] According to one embodiment of the present invention, referring to Figure 1 and Figure 2As 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 .

[0136] It can be understood that in this embodiment, the distance between the rear baffle 132 and the middle baffle 123 is adjusted by setting the distance adjusting member 140, so as to achieve the purpose of adjusting the width of the advection wave generated by the advection wave generating assembly 130. When the distance adjusting member 140 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. On the contrary, if the distance adjusting member 140 is adjusted to reduce 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 adjusting member 140, the width of the advection wave can be flexibly controlled to meet specific welding requirements and workpiece characteristics. In actual operation, it is necessary to appropriately adjust the distance adjusting member 140 according to the needs of the welding process and the desired effect to obtain the optimal advection wave width.

[0137] During the welding process, adjusting the width of the advection wave can affect the welding speed and heat input. A narrower advection wave will result in a faster welding speed and a relatively smaller heat input; while a wider advection wave will slow down the welding speed and increase the heat input. By adjusting the width of the advection wave, the welding speed and heat input can be better controlled, thereby affecting the formation and quality of the weld; a narrower advection wave will result in a narrower weld, a higher weld height, and a sharper weld morphology; while a wider advection wave will result in a wider weld, a lower weld height, and a flatter weld morphology. Properly adjusting the width of the advection wave can obtain a weld morphology and welding quality that better meets the requirements. In actual operation, the operator can reasonably adjust the width of the advection wave according to the specific welding requirements and workpiece characteristics to achieve the best welding effect.

[0138] 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.

[0139] It can be understood that in this embodiment, since the rear baffle 132 is installed on the advection plate 131, the distance between the middle baffle 123 and the rear baffle 132 can be adjusted by adjusting the relative position of the advection plate 131 and the middle baffle 123, thereby achieving the adjustment of the advection wave width to meet the requirements of the welding process.

[0140] 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 connector whose length is suitable for passing through the first adjustment long hole 141 and connecting the middle baffle 123 and the float plate 131 to fix the distance between the middle baffle 123 and the rear baffle 132.

[0141] When the width of the advection wave needs to be changed, the first positioning bolt 142 only needs to be loosened, and the position of the first adjustment slot 141 needs to be adjusted, and then the distance between the rear baffle 132 and the middle baffle 123 is fixed by tightening the first positioning bolt 142. Through the cooperation of the first positioning bolt 142 and the first adjustment slot 141, the distance between the rear baffle 132 and the middle baffle 123 can be easily adjusted to meet different welding requirements and workpiece characteristics. At the same time, the distance adjustment member 140 can also effectively control the width of the advection wave and improve welding quality and efficiency.

[0142] According to one embodiment of the present invention, referring to Figure 1 and 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 advection plate 131 .

[0143] It is understandable that in this embodiment, by providing a plurality of first adjustment slots 141 on the advection plate 131, more adjustment options and flexibility can be provided, and each first adjustment slot 141 can use a corresponding positioning bolt to fix the distance between the middle baffle 123 and the rear baffle 132. At the same time, the plurality of first adjustment slots 141 are arranged at intervals along the length direction of the advection plate 131, so that the distance adjustment at various locations of the advection plate 131 can be kept consistent, ensuring that the middle baffle 123 and the rear baffle 132 are parallel during the adjustment process, and ensuring the stability and consistency of the welding process.

[0144] In an optional embodiment, scale indicator lines are arranged around the first adjustment slot 141 , and the scale indicator lines can facilitate the user to determine the adjustment distance between the middle baffle 123 and the rear baffle 132 , thereby improving the adjustment accuracy.

[0145] Through the scale indicator line, the operator can intuitively read the adjustment distance, avoiding the trouble of additional measurement, and also reducing the possibility of inaccurate adjustment due to errors. This design can greatly simplify the operation process, improve work efficiency, and ensure the accuracy of distance adjustment during welding. The setting of the scale indicator line makes the distance adjustment between the middle baffle 123 and the rear baffle 132 more intuitive and convenient, especially when the advection wave width needs to be adjusted frequently, which can greatly improve work efficiency.

[0146] The embodiment of the second aspect of the utility model refers 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-mentioned 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.

[0147] In this embodiment, the tin furnace 400 is a device for melting soldering materials (such as solder such as tin), which is formed with a tin cavity for containing and heating the soldering materials, and the driving device 20 is used to control the flow and injection of the soldering materials. The driving device 20 is connected to the tin cavity and the wave soldering nozzle structure 10, and the molten soldering materials are transported from the tin cavity to the wave soldering nozzle structure 10 through a pump or other driving mechanism. The wave soldering nozzle structure 10 is arranged in the tin furnace 400 and is connected to the driving device 20. The function of the wave soldering nozzle structure 10 is to generate advection waves and turbulence waves to solder the circuit board.

[0148] The working principle of the whole device is that the driving 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 flow waves and turbulent waves according to the design principle. These waves help to improve the quality and efficiency of soldering. The solder material is sprayed to the soldering area through the wave soldering nozzle structure 10 to complete the soldering process of the circuit board and electronic components.

[0149] In the related art, the wave soldering nozzle structure 10 can generate turbulent waves and horizontal waves to solder the circuit board. 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 not convenient to adjust, which can easily lead to unstable welding quality and affect welding efficiency.

[0150] 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, wherein the tin furnace 400 forms a tin cavity; the wave soldering nozzle structure 10 is disposed in the tin cavity, and the wave soldering nozzle structure 10 includes a base 110 and a flat wave generating assembly 130 disposed on the base 110; the height adjustment member 160 includes an operating portion 163 and a transmission portion 164, wherein the operating portion 163 is connected to the flat wave generating assembly 130 through the transmission portion 164 so that the flat wave generating assembly 130 moves in the up and down directions to adjust the height of the flat wave generating assembly 130, and the operating portion 163 is at least partially disposed outside the tin cavity.

[0151] It can be understood that in this embodiment, the height adjustment member 160 includes an operating part 163 and a transmission part 164, and the height adjustment of the flat wave generating assembly 130 is achieved through the operating part 163 and the transmission part 164, so as to achieve the purpose of adjusting the flat wave height, thereby adjusting the tin amount of the tin point and reducing the occurrence of poor soldering and tin bridges, thereby improving the welding quality; the operating part 163 is arranged outside the tin furnace 400, and the operator can directly adjust the height through the operating part 163 without opening the tin furnace 400 or moving the equipment, so that the operation is more convenient and quick. Since the operating part 163 is at least partially arranged outside the tin furnace 400, the operator can reduce the chance of contact with high-temperature equipment, reduce the operating risk, and improve the work safety. Moreover, the height of the flat wave generating assembly 130 can be accurately controlled through the transmission part 164, so as to achieve accurate adjustment of the flat wave height, thereby improving the welding quality and production efficiency. By adjusting the height of the flat wave outside the tin furnace 400, it can be flexibly adjusted according to different welding requirements and workpiece characteristics, meet different welding requirements, and be suitable for different types of workpieces, thereby improving the versatility and flexibility of the equipment.

[0152] According to one embodiment of the present invention, referring to Figure 7 As shown, the advection wave generating assembly 130 includes a middle baffle 123 and a rear baffle 132 that are relatively arranged, and an advection plate 131. The transmission part 164 is connected to the rear baffle 132 to adjust the height of the rear baffle 132. The advection plate 131 connects the middle baffle 123 and the rear baffle 132. A advection cavity is formed between the middle baffle 123, the advection plate 131 and the rear baffle 132 for generating advection waves.

[0153] It is understandable that in this embodiment, the transmission part 164 is connected to the rear baffle 132, and the height of the rear baffle 132 can be accurately adjusted by controlling the movement of the transmission part 164, thereby realizing accurate adjustment of the height of the advection wave. The transmission part 164 connection structure for adjusting the height of the rear baffle 132 is reasonably designed and relatively easy to operate. The operator can easily adjust the height, thereby improving production efficiency. By adjusting the height of the advection wave, it can meet the needs of different welding requirements and workpiece specifications, so that the equipment has better applicability and flexibility in different scenarios. By accurately adjusting the height of the advection wave, the shape and height of the wave crest during the welding process can be controlled, thereby ensuring welding quality and stability.

[0154] 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 rear baffle 132.

[0155] In an optional embodiment, the transmission part 164 adopts a gear transmission, which transmits motion and force through the mutual meshing of gears, and can achieve more precise height adjustment. By adjusting the size of the gear and the ratio of the number of teeth, the height of the rear baffle 132 can be slightly adjusted, which is suitable for occasions requiring higher precision.

[0156] In another optional embodiment, the transmission part 164 adopts a screw drive, which utilizes the helical side effect of the nut and the screw to convert the rotational motion into a linear displacement, thereby realizing the precise adjustment of the height of the rear baffle 132. The screw drive has high transmission efficiency and precision, and is suitable for occasions requiring precise adjustment.

[0157] In another optional embodiment, the transmission part 164 adopts hydraulic transmission, which transmits pressure through the hydraulic system to achieve motion control. The height of the rear baffle 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.

[0158] In another optional embodiment, the transmission part 164 adopts chain transmission. The chain transmission uses the cooperation of chains and gears to transmit motion and force, which can achieve relatively stable and reliable transmission and adjust the height of the rear baffle 132.

[0159] According to an embodiment of the utility model, the tin furnace 400 is provided with a mounting seat, and the operating part 163 is rotatably disposed on the mounting seat. The mounting seat can provide a stable support, so that the operating part 163 is more stable during operation. During the adjustment process, the operator only needs to adjust the tin furnace 400 by rotating the operating part 163, without the need for complex adjustments or movements, and the operation is simple and quick.

[0160] In this embodiment, the operating part 163 can be designed as a handle, a knob or other structure. In an optional embodiment, by rotating or pushing and pulling the handle, the displacement of the transmission part 164 can be controlled, thereby adjusting the height of the rear baffle 132. The handle operation is simple and intuitive, and can be suitable for occasions where the height of the rear baffle 132 needs to be frequently adjusted. In another optional embodiment, the transmission part 164 can be controlled by rotating the knob, thereby adjusting the height of the rear baffle 132. The design of the knob is flexible in operation and can be used in conjunction with the scale line, which is suitable for occasions where small adjustments are required.

[0161] 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.

[0162] It is understandable that in this embodiment, the operator can drive the transmission part 164 to move by rotating the operating part 163 (such as a handle, a knob, etc.), and when the operating part 163 rotates, the transmission screw will slide up and down along the guide groove 134. The movement of the transmission screw will drive the movement of the nut matched therewith, so that the rear baffle 132 moves in the up and down direction, so as to adjust the height of the rear baffle 132.

[0163] As required, the operator can gradually rotate or push and pull the operating part 163 to fine-tune the height of the rear baffle 132 until the requirement is met without using complex tools or performing cumbersome operations. The advantage of this adjustment method is that the operation is simple and the height of the rear baffle 132 can be adjusted by the transmission screw to achieve high precision.

[0164] According to an embodiment of the utility model, the rear baffle 132 is provided with a guide groove 134, and the nut is slidably arranged in the guide groove 134. It helps to ensure that the nut maintains the correct direction and position during the movement. The guide groove 134 can effectively guide the movement of the nut to prevent it from deviating during the movement. At the same time, the existence of the guide groove 134 can ensure the relative stability of the nut during the movement, avoid the deflection or shaking of the rear baffle 132 during the height adjustment process, thereby ensuring the stability of the rear baffle 132 during the height adjustment process.

[0165] According to an embodiment of the present invention, the guide groove 134 is arranged along the up-down direction of the rear baffle 132. By arranging the guide groove 134 along the up-down direction, the movement of the nut is directly associated with the up-down movement of the rear baffle 132, and the operator can more directly control the height adjustment of the rear baffle 132. Since the guide groove 134 limits the movement direction of the nut, the up-down movement of the rear baffle 132 can be more accurately controlled, making the height adjustment more precise.

[0166] 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 plate 132 away from the middle baffle plate 123 .

[0167] It is understandable that in this embodiment, by providing a tin slag collection tank 170 on one side of the rear baffle 132, the tin slag generated during the flat wave soldering process can be collected, which facilitates the cleaning of the tin slag. Tin slag is a byproduct generated during the wave soldering process, which may be deposited on the components of the soldering equipment, causing pollution and blockage of the equipment, and even affecting the soldering quality. Therefore, providing a tin slag collection tank 170 helps to avoid these problems and improve the reliability and service life of the equipment.

[0168] By arranging the tin slag collecting tank 170 on the side of the rear baffle plate 132 away from the middle baffle plate 123, it can be relatively independent from the welding area, reducing the interference of the tin slag on the welding process, and at the same time reducing the possibility of the tin slag falling back into the tin furnace 400, reducing the contamination of the solder in the tin furnace 400. After welding, the operator can easily clean the tin slag collecting tank 170 to keep the equipment clean and in good working condition, which is helpful to improve the stability and maintainability of the wave soldering equipment, and has a good effect on ensuring the welding quality and normal operation of the equipment.

[0169] According to one embodiment of the present invention, referring to Figure 7 As shown, the tin slag collecting tank 170 is disposed above the tin cavity, and the tin slag collecting tank 170 is provided with a through hole 171 communicating with the tin cavity.

[0170] It is understandable that in this embodiment, during the soldering process of the wave soldering equipment, the solder ejected from the flat wave nozzle 1301 will form a solder wave and flow along the soldering area. A portion of the solder may splash or fall into the tin slag collecting tank 170. By providing a through hole 171 connected to the tin cavity, the solder can flow back from the through hole 171 of the tin slag collecting tank 170 to the tin cavity, realizing the reflux circulation of the solder, maintaining the stable supply of solder in the tin cavity, and ensuring the consistency and stability of the soldering quality.

[0171] 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.

[0172] 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 arranged at intervals along the length direction and / or width direction of the tin slag collecting trough 170 .

[0173] 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, and by reasonably providing a plurality of through holes 171, a more uniform solder reflux distribution can be achieved, thereby improving the reflux efficiency.

[0174] In an optional embodiment, the size and number of the through holes 171 need to be reasonably designed according to 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.

[0175] 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 the height of the second side 173 , and the first side 172 is provided with a through hole 171 .

[0176] It can be understood that in this embodiment, the tin slag collecting 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.

[0177] In this embodiment, the first side 172 and the second side 173 can be two opposite sides of the tin slag collecting groove 170 along the length direction, or can be two opposite sides of the tin slag collecting groove 170 along the width direction. When the first side 172 is set lower along the length direction of the tin slag collecting groove 170, the solder can be encouraged to flow naturally to the position of the through hole 171 and smoothly flow back into the tin furnace 400. Similarly, when the first side 172 is set lower along the width direction of the tin slag collecting groove 170, the solder can also be smoothly refluxed, which is not specifically limited in this embodiment.

[0178] For example, in an optional embodiment, the height of the tin slag collecting trough 170 close to the flat wave generating assembly 130 is lower than the height away from the flat wave generating assembly 130, and the through hole 171 is arranged at the end of the tin slag collecting trough 170 close to the flat wave generating assembly 130.

[0179] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the wave soldering nozzle structure 10 is formed with a wave crest nozzle, the wave crest nozzle is connected with the guide cavity, and the wave crest nozzle is formed with a turbulent wave area and a flat wave area.

[0180] Exemplarily, the wave crest nozzle is formed with a spoiler wave nozzle 1201 located in the spoiler wave area and a flat wave nozzle 1301 located in the flat wave area. Both the spoiler wave nozzle 1201 and the flat wave nozzle 1301 are connected to the guide cavity. Only one driving motor is needed to transport the solder into the guide cavity to realize the welding work of the spoiler wave nozzle 1201 and the flat wave nozzle 1301, which simplifies the operation steps, reduces the operation complexity, and thus improves the work efficiency. In the whole welding process, only one driving motor is needed to transport the solder. Compared with the traditional two motors driving the spoiler wave generating component 120 and the flat wave generating component 130 respectively, the energy consumption is reduced and the production cost is reduced.

[0181] It should be noted that the spoiler wave generating assembly 200 and the flat wave generating assembly 300 in the present embodiment share the same nozzle, that is, the spoiler wave nozzle 201 and the flat wave nozzle 301 are actually the same crest nozzle, but the nozzle is divided into two different areas, and the spoiler wave nozzle 201 and the flat wave nozzle 301 are respectively located in different areas of the crest nozzle. Therefore, the spoiler wave nozzle 201 and the flat wave nozzle 301 are both connected with the guide cavity, and only need to convey the solder into the guide cavity through a driving motor, so that the spoiler wave nozzle 201 and the flat wave nozzle 301 can be realized to perform welding work, realize the double wave integration of spoiler wave and flat wave, that is, the spoiler wave assembly and the flat wave assembly can work at the same time, simplify the operation steps, reduce the complexity of operation, thereby improving work efficiency, and only need one driving motor to convey the solder in the whole welding process, compared with the traditional two motors driving the spoiler wave generating assembly 200 and the flat wave generating assembly 300 to work respectively, reducing energy consumption and reducing production costs.

[0182] It can be understood that the wave soldering nozzle structure 10 has the beneficial effects of the above-mentioned embodiments, and the wave soldering equipment correspondingly has the beneficial effects of the above-mentioned embodiments. The specific implementation methods thereof may refer to the above-mentioned embodiments, and will not be described in detail in this application.

[0183] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not deviate from the spirit and scope of the technical solutions of the present invention, and should be included in the protection scope of the present invention.
