Welding is an essential key process in the manufacturing of these products. When welding components such as circuit boards and circuit cards, solder plays a crucial role as the main material. However, a large amount of waste solder dross is inevitably generated during the welding process. Waste solder dross is a waste generated during the welding process, and people usually manually salvage and discard it. However, waste solder dross actually contains important resource value.

[0047] For the dross salvage system according to the embodiments of the present utility model, please refer to Figures 1 to 6, the dross salvage system includes a tin furnace 400, a dross separation device 10, a dross salvage device 20, and a driving motor 330. A solder space 401 is formed inside the tin furnace 400; the dross separation device 10 includes a separation main body 100 and a stirring and separating component 310. An accommodation cavity 101 is formed inside the separation main body 100. The separation main body 100 is provided with a feed inlet 102, a dross discharge outlet 103, and a solder discharge outlet 104 that communicate with the accommodation cavity 101. The solder discharge outlet 104 communicates with the solder space 401. The stirring and separating component 310 is disposed in the accommodation cavity 101 and is used to drive the mixture in the accommodation cavity 101 to rotate centrifugally to achieve dross separation; the dross salvage device 20 includes a dross transfer mechanism 21. The starting end of the dross transfer mechanism 21 is disposed near the solder space 401, and the ending end is disposed near the feed inlet 102; the driving motor 330 is used to drive the stirring and separating component 310 and the dross transfer mechanism 21 to move.

[0048] In the dross salvage system according to the embodiment of the present invention, the dross transfer mechanism 21 can automatically salvage the dross in the solder space 401 and transfer it to the dross separation device 10. Then, the dross separation device 10 separates the dross and the solder, avoiding the cumbersome and error-prone manual sorting, improving the work efficiency, and realizing the automatic processing of the dross. At the same time, the separated solder can re-enter the solder space 401 for recycling, realizing the maximum utilization of resources. One driving motor 330 can drive the stirring and separating component 310 and the dross transfer mechanism 21 to move, with higher energy utilization efficiency, and can also realize the coordinated work between the dross separation device and the dross salvage device.

[0049] It can be understood that the solder space 401 formed inside the tin furnace 400 provides a stable solder source for the welding operation. During the welding process, dross will be continuously formed and will fall back into the tin furnace 400. The dross salvage device 20 can salvage the dross from the solder space 401. The dross salvage device 20 is mainly composed of a dross transfer mechanism 21. The starting end of the dross transfer mechanism 21 is disposed in the solder space 401, and the ending end is connected to the feed inlet 102 of the dross separation device 10. Finally, the dross separation device 10 separates the dross and the solder.

[0050] Specifically, the stirring and separating component 310 is disposed inside the accommodation cavity 101. When the driving motor 330 drives it to rotate, it can drive the mixture of dross and solder in the accommodation cavity 101 to rotate centrifugally. Due to the different physical properties of the dross and the solder, under the action of centrifugal force, the two can be effectively separated. The separated dross is discharged from the dross discharge outlet 103, and the solder re-enters the solder space 401 through the solder discharge outlet 104 for recycling.

[0051] It should be noted that a driving motor 330 drives the stirring and separating component 310 and the dross conveying mechanism 21, which not only simplifies the system structure but also improves the energy utilization efficiency. At the same time, through an accurate control system, the coordinated operation between the dross separation device and the dross salvage device can be achieved.

[0052] The starting end of the dross conveying mechanism 21 is arranged at and near the solder space 401. Specifically, the starting end of the dross conveying mechanism 21 can be located in the solder space 401 or can also be arranged near the solder space 401, as long as the solder can enter the starting end of the dross conveying mechanism 21 and be sent to the feeding port 102. The vicinity of the solder space 401 can be understood as one of the upper part, lower part, front part, rear part, left part, and right part of the solder space 401.

[0053] The ending end of the dross conveying mechanism 21 is arranged at and near the feeding port 102. Specifically, the ending end of the dross conveying mechanism 21 can be arranged at the feeding port 102 or can also be arranged near the feeding port 102, as long as the solder conveyed to the ending end can be accurately sent to the feeding port 102. The vicinity of the feeding port 102 can be understood as one of the upper part, front part, rear part, left part, and right part of the feeding port 102.

[0054] According to an embodiment of the present invention, a first transmission component 320 is arranged between the driving motor 330 and the stirring and separating component 310, and a second transmission component 80 is arranged between the driving motor 330 and the dross conveying mechanism 21. At least one of the first transmission component 320 and the second transmission component 80 has a reverse transmission with the driving motor 330.

[0055] It can be understood that a first transmission component 320 is arranged between the driving motor 330 and the stirring and separating component 310, and this component can transmit the power of the driving motor 330 to the stirring and separating component 310 to make it perform a rotational motion. At the same time, a second transmission component 80 is arranged between the driving motor 330 and the dross conveying mechanism 21 to transmit power to make the dross conveying mechanism 21 work properly.

[0056] It can be understood that at least one of the first transmission component 320 and the second transmission component 80 has a reverse transmission design with the driving motor 330. The reverse transmission can not only change the power transmission direction but also adjust the transmission ratio according to needs, so as to achieve precise control of the movement speed and direction of the stirring and separating component 310 and the dross conveying mechanism 21.

[0057] According to an embodiment of the present invention, please refer toFigure 1 and Figure 2 The output shaft of the driving motor 330 is provided with an output helical gear, and at least one of the first transmission component 320 and the second transmission component 80 is provided with a driven helical gear, and the output helical gear is connected to the driven helical gear.

[0058] It is understandable that when the driving motor 330 is working, its output shaft drives the output bevel gear to rotate, and the output bevel gear transmits power to the corresponding first transmission component 320 or the second transmission component 80 through meshing with the driven bevel gear. The bevel gear transmission mode has the advantages of high transmission efficiency, large transmission torque, stable and reliable operation, etc., which can effectively ensure the efficient and stable operation of the tin slag salvage system.

[0059] The bevel gear can change the direction of power transmission, so that the tin slag conveying mechanism 21 and the stirring and separating component 310 can move simultaneously.

[0060] In addition, the helical gear transmission also has a self-locking function, that is, under certain conditions, even if the driving motor 330 stops working, the driven helical gear can maintain its original position, thereby avoiding system loss of control due to unexpected situations.

[0061] According to an embodiment of the present invention, the output shaft of the driving motor 330 is provided with a worm gear or a worm (not shown in the figure), and at least one of the first transmission component 320 and the second transmission component 80 is provided with a corresponding worm gear or a worm gear.

[0062] It is understandable that when the driving motor 330 is started, the worm gear or worm on its output shaft starts to rotate, and through precise meshing, power is transmitted to the corresponding worm gear or worm gear, thereby driving the first transmission component 320 or the second transmission component 80 to work.

[0063] Likewise, the worm gear can change the direction of power transmission, so that the tin slag conveying mechanism 21 and the stirring and separating component 310 can move simultaneously.

[0064] In addition, the worm gear and worm transmission also has a self-locking function, which means that even if the drive motor 330 stops working or loses power, the first transmission component 320 can maintain its original position and will not move accidentally due to external forces, thereby greatly improving the safety and stability of the system.

[0065] During the actual operation of the tin slag salvage system, this transmission mechanism can ensure that the stirring and separation component 310 and the tin slag conveying mechanism 21 can move accurately at a predetermined speed and direction after receiving the power of the drive motor 330, thereby achieving efficient salvage and separation of the tin slag.

[0066] According to an embodiment of the present utility model, the output shaft of the driving motor 330 is parallel to the rotating shaft 311 of the stirring and separating component 310. The power transmission path between the two is more direct and concise, avoiding complex steering and power loss during the transmission process, enabling the power of the driving motor 330 to be transmitted to the stirring and separating component 310 more efficiently, and realizing its efficient rotation.

[0067] In addition, the parallel rotating shaft 311 also facilitates the installation and debugging of the stirring and separating component 310. During the installation process, it is easier to align and fix the driving motor 330 and the stirring and separating component 310, ensuring their precise cooperation.

[0068] According to an embodiment of the present utility model, the driving motor 330 is disposed outside the tin furnace 400. It can be understood that by disposing the driving motor 330 outside the tin furnace 400, direct contact between the motor and the high-temperature tin furnace 400 can be effectively avoided, thereby preventing the motor from overheating or being damaged, ensuring that the motor can operate in a suitable working environment, extending its service life, and reducing the risk of failures caused by high temperature.

[0069] According to an embodiment of the present utility model, please refer to Figure 3 and Figure 4 , the solder dross conveying mechanism 21 includes a conveyor belt 29 and a rotating shaft 30. The number of rotating shafts 30 is at least two, all rotating shafts 30 are spaced apart and rotatably connected to the tin furnace 400, and the driving motor 330 is adapted to drive one of the rotating shafts 30 to rotate, and the conveyor belt 29 is sleeved on all the rotating shafts 30.

[0070] It can be understood that the driving motor 330 is connected to one of the rotating shafts 30 through a second transmission component 80. When the driving motor 330 operates, it can drive the rotating shaft 30 to rotate, and then drive the entire conveyor belt 29 to perform a circular motion. The conveyor belt 29 is sleeved on all the rotating shafts 30 to form a closed circular loop. Driven by the conveyor belt 29, the solder dross can be smoothly conveyed from the starting end of the solder space 401 to the feeding port 102 of the solder dross separation device 10.

[0071] According to an embodiment of the present utility model, at least one of the rotating shafts 30 is disposed in the solder space 401.

[0072] During the soldering process, solder dross will continuously generate and accumulate in the solder space 401. Through the rotating shaft 30 disposed in the solder space 401, the conveyor belt 29 can closely adhere to the surface of the solder dross, effectively scrape and convey the solder dross from the bottom of the solder space 401, ensuring that the solder dross can leave the solder space 401 in a timely and efficient manner, preventing the accumulation and blockage of the solder dross.

[0073] Another rotating shaft 30 is arranged above the feeding port 102, so that the conveyor belt 29 can be smoothly lifted when it reaches the feeding port 102, and the solder dross is poured into the solder dross separation device 10. This ensures that the solder dross can accurately enter the solder dross separation device 10, avoiding the scattering and waste of the solder dross during the conveying process.

[0074] In one embodiment, by adjusting the heights of the two rotating shafts 30, the precise control of the inclination angle of the conveyor belt 29 can be achieved, thereby further optimizing the conveying efficiency and accuracy of the solder dross.

[0075] According to one embodiment of the present invention, please refer to Figure 3 and Figure 4 , the solder dross conveying mechanism 21 includes stoppers 25. The number of stoppers 25 is multiple, and the multiple stoppers 25 are arranged on the first conveying member 22 along the conveying direction of the first conveying mechanism 40, and the stoppers 25 are arranged at intervals to form a fishing chamber 26.

[0076] It can be understood that the stoppers 25 are orderly arranged on the first conveying member 22 along the conveying direction of the first conveying mechanism 40, ensuring that the solder dross can be smoothly conveyed along the set path, and avoiding the scattering and waste of the solder dross during the conveying process. The intervals between the stoppers 25 together form multiple fishing chambers 26. These fishing chambers 26 are like "temporary warehouses" in the solder dross conveying mechanism 21, and they can temporarily store the solder dross during the conveying process of the solder dross.

[0077] According to one embodiment of the present invention, please refer to Figure 3 and Figure 4 , the solder dross fishing device 20 further includes a lifting mechanism 27, and the lifting mechanism 27 is used to change the height of the starting end of the solder dross conveying mechanism 21.

[0078] It can be understood that the lifting mechanism 27 can help optimize the fishing effect of the solder dross. By adjusting the height of the solder dross conveying mechanism 21, it can be closer to the solder dross layer on the surface of the solder, thereby improving the fishing efficiency. At the same time, the lifting mechanism 27 can also be adjusted according to the actual situation of the solder space 401 to ensure that the solder dross conveying mechanism 21 maintains the best working angle and position during the fishing process.

[0079] It should be noted that the lifting mechanism 27 can adopt any common lifting mechanism 27 on the market, and no specific limitation is made here.

[0080] According to one embodiment of the present invention, the solder dross conveying mechanism 21 includes a first conveying member 22 and a first baffle 23. The first conveying member 22 is located in the solder space 401, and the first conveying member 22 is adapted to convey the solder dross along a first direction. The first baffle 23 extends along the first direction and is arranged on at least one side of the first conveying member 22.

[0081] It can be understood that the first conveying member 22 is located within the solder space 401 and can convey the dross along the first direction. In other words, the dross can be automatically collected from the solder space 401 and conveyed to subsequent processing steps, greatly improving the work efficiency and the degree of automation of the operation. The first baffle 23 extending along the first direction can effectively prevent the dross from falling or overflowing from the side of the conveying member during the conveying process. The baffle plays a guiding and fixing role, ensuring that the dross can be stably conveyed to the dross separation device 10.

[0082] According to an embodiment of the present invention, at least one telescopic member 24 is provided between the first baffle 23 and the first conveying member 22, and the telescopic member 24 is adapted to adjust the distance between the first baffle 23 and the first conveying member 22.

[0083] It can be understood that by adjusting the telescopic member 24, the distance between the first baffle 23 and the first conveying member 22 can be flexibly changed, thereby expanding the fishing range of the first conveying member 22. The first conveying member 22 can not only transmit the dross located above it to the dross separation device 10, but also gather the nearby dross above it by adjusting the telescopic member 24, greatly increasing the fishing range.

[0084] Specifically, when the telescopic member 24 is adjusted to a shorter length, the distance between the first baffle 23 and the first conveying member 22 is reduced, which enables the dross conveying mechanism 21 to fit more closely to the surface of the dross when fishing for dross, ensuring that more dross is effectively conveyed to the dross separation device 10. When the telescopic member 24 is adjusted to a longer length, the distance between the first baffle 23 and the first conveying member 22 is increased, which enables the first conveying member 22 to cover a larger area and gather and convey the dross scattered in a wider area to the dross separation device 10.

[0085] This adjustability not only improves the fishing efficiency of the dross conveying mechanism 21, but also enables the mechanism to better adapt to different dross distribution situations and operating environments. Whether facing densely piled dross or scattered dross, the fishing effect can be optimized by adjusting the telescopic member 24.

[0086] According to an embodiment of the present invention, the lifting mechanism 27 is connected to the starting end of the dross conveying mechanism 21, and one of the middle sections or the end of the dross conveying mechanism 21 is rotatably connected to the soldering furnace 400.

[0087] It can be understood that when the lifting mechanism 27 adjusts the height, the solder dross conveying mechanism 21 can rotate accordingly. That is, when the lifting mechanism 27 adjusts the height position of the starting end, the end point of the solder dross conveying mechanism 21 is still set at the position of the feeding port 102 to ensure the stable conveyance of the solder dross.

[0088] The solder dross conveying mechanism 21 may include a first conveying mechanism 40 and a second conveying mechanism 50. The first conveying mechanism 40 is used to salvage the solder dross located in the solder space 401. A plurality of second conveying mechanisms 50 may be provided to convey the solder dross of the first conveying mechanism 40 to the feeding port 102. The starting end of the first conveying mechanism 40 is set in the solder space 401, the end point of the first conveying mechanism 40 is connected to the starting end of the second conveying mechanism 50, and the end point of the second conveying mechanism 50 is set at the feeding port 102.

[0089] It should be noted that one place in the middle section of the solder dross conveying mechanism 21 and the starting end of the solder dross conveying mechanism 21 are the first conveying mechanism 40.

[0090] Among them, the lifting mechanism 27 is connected to the first conveying mechanism 40, and the first conveying mechanism 40 can change the height direction as a whole. For example, the first conveying mechanism 40 can be lifted and lowered along the height direction as a whole. The first conveying mechanism 40 can also change the local height direction. For example, the lifting mechanism 27 is connected to the starting end of the first conveying mechanism 40, and the end point of the first conveying mechanism 40 is rotatably connected to the solder furnace 400, so that the starting end of the first conveying mechanism 40 can rotate around the end point of the first conveying mechanism 40 to change the height.

[0091] According to an embodiment of the present invention, the solder dross conveying mechanism 21 is provided with a plurality of reflux holes 28. The reflux holes 28 penetrate through the solder dross conveying mechanism 21 and communicate with the solder space 401, and the solder flows back to the solder space 401 through the reflux holes 28.

[0092] Specifically, when the solder dross conveying mechanism 21 works in the solder space 401, it may inevitably carry some solder. By providing the reflux holes 28, these redundant solders can flow back to the solder space 401 smoothly, avoiding the waste and loss of the solder. At the same time, this also ensures that the solder dross conveying mechanism 21 mainly conveys the solder dross rather than the solder, thereby improving the efficiency and accuracy of solder dross separation.

[0093] According to an embodiment of the present utility model, a working device 60 is disposed inside the soldering furnace 400. The dross conveying mechanism 21 includes a first conveying mechanism 40 and a second conveying mechanism 50. The starting end of the first conveying mechanism 40 is disposed in the solder space 401. The ending end of the first conveying mechanism 40 is connected to the starting end of the second conveying mechanism 50. The ending end of the second conveying mechanism 50 is disposed at the feed inlet 102. The conveying directions of the first conveying mechanism 40 and the second conveying mechanism 50 are different and are used to avoid the working device 60.

[0094] Specifically, the starting end of the first conveying mechanism 40 is disposed in the solder space 401, which means that it can directly contact the dross in the soldering furnace 400 and effectively salvage it. The ending end of the first conveying mechanism 40 is connected to the starting end of the second conveying mechanism 50, forming a continuous conveying path. The ending end of the second conveying mechanism 50 is disposed at the feed inlet 102 and is responsible for conveying the salvaged dross to the dross separation device 10.

[0095] When the soldering furnace 400 is working, the working device 60 (such as a soldering device, a heating element, a stirring device, etc.) inside it may occupy a certain space and needs to perform specific movements. By making the first conveying mechanism 40 and the second conveying mechanism 50 convey in different directions, it can effectively avoid their interference or collision with the working device 60, thereby ensuring the safety and stability of the entire dross salvage system. Moreover, it also ensures that the work of the working device 60 and the work of the dross salvage device 20 do not affect each other, and even the work of salvaging and the work of the working device 60 can be carried out synchronously, thereby improving work efficiency.

[0096] According to the dross separation system of the embodiment of the present utility model, the dross separation system includes a soldering furnace 400, a dross collection box 500, a separation main body 100, and a separation mechanism 300. A solder space 401 is formed inside the soldering furnace 400. The dross collection box 500 is connected to the soldering furnace 400, and a dross space 501 is formed inside it. The dross space 501 and the solder space 401 are independent of each other. An accommodation cavity 101 is formed inside the separation main body 100. The separation main body 100 is provided with a feed inlet 102, a dross discharge port 103, and a solder discharge port 104 that communicate with the accommodation cavity 101. The dross discharge port 103 communicates with the dross space 501, and the solder discharge port 104 communicates with the solder space 401. The separation mechanism 300 is used to drive the mixture in the accommodation cavity 101 to rotate centrifugally to achieve dross separation. During the dross separation process, at least a part of the separation main body 100 is located below the solder liquid level in the solder space 401 to heat the accommodation cavity 101 through the solder in the solder space 401. The separated solder enters the solder space 401 through the solder outlet, and the separated dross enters the dross space 501 through the dross discharge port 103.

[0097] According to the solder dross separation system of the embodiments of the present utility model, through the centrifugal rotation of the separation mechanism 300 and the heat energy supply of the solder furnace 400, the solder dross separation system can efficiently separate the solder and the solder dross in the waste solder dross. During the process of separating the solder dross, at least a part of the separation main body 100 is located below the liquid level of the solder in the solder furnace 400. The solder furnace 400 can provide sufficient heat for the separation main body 100, so that the mixture can be fully liquefied, ensuring the smooth progress of the solder dross separation. The centrifugal rotation of the separation mechanism 300 causes the solder and the solder dross with different densities to leave the accommodation cavity 101 from the solder dross discharge port 103 and the solder discharge port 104 respectively under the action of centrifugal force.

[0098] It can be understood that a solder space 401 is formed inside the solder furnace 400, and the solder stored in the solder space 401 can be used as the raw material for welding. The solder furnace 400 can provide heat energy to heat the mixture in the accommodation cavity 101, which can promote the solder dross separation process. It should be noted that the solder dross separation process here can be understood as separating the reusable solder and the non-reusable solder dross, and entering different storage spaces (the solder dross space 501 and the solder space 401) from different discharge ports (the solder dross discharge port 103 and the solder discharge port 104).

[0099] It can be understood that the solder dross space 501 of the solder dross collection box 500 and the solder space 401 of the solder furnace 400 are independent of each other. The separated solder enters the solder space 401 through the solder discharge port 104 for collection, while the separated solder dross enters the solder dross space 501 through the solder dross discharge port 103, which is convenient for the operator to recycle the solder after solder dross separation and to process the solder dross after solder dross separation.

[0100] It can be understood that the separation mechanism 300 can drive the mixture in the accommodation cavity 101 to rotate, so that the solder dross and the solder with different densities are separated. The solder dross with a small density floats above the solder, and under the action of centrifugal force, it enters the solder dross space 501 through the solder dross discharge port 103.

[0101] According to an embodiment of the present utility model, the solder dross separation system further includes a fixed support frame 600, and the fixed support frame 600 is used to fix the separation main body 100 to the inner wall of the solder furnace 400.

[0102] It can be understood that the fixed support frame 600 can firmly fix the separation main body 100 to the inner wall of the solder furnace 400, prevent it from moving or shaking during operation, and ensure the stability and reliability of the separation process.

[0103] It can be understood that the fixed support frame 600 only needs to fix the separation main body 100 to the inner wall of the soldering furnace 400. The fixed support frame 600 can be connected to the inner wall of the soldering furnace 400, can also be connected to the outer surface of the soldering furnace 400, or can be hung on the edge of the soldering furnace 400.

[0104] According to an embodiment of the present invention, the fixed support frame 600 is a U-shaped frame. The U-shaped frame is arranged around the outer contour of the separation main body 100, and the ends of the U-shaped frame are fixed to the inner wall of the soldering furnace 400.

[0105] It can be understood that the shape design of the U-shaped frame enables it to completely surround the outer contour of the separation main body 100, providing comprehensive support, effectively enhancing the stability of the fixed support frame 600, and ensuring a firm connection between the support frame and the soldering furnace 400.

[0106] Specifically, the ends of the U-shaped frame can be fixedly installed on the soldering furnace 400 by screws.

[0107] According to an embodiment of the present invention, during the process of separating solder dross, the accommodating cavity 101 is located in the solder space 401, and the solder discharge port 104 is arranged at the bottom of the separation main body 100.

[0108] It can be understood that the accommodating cavity 101 being located in the solder space 401 can utilize the temperature of the liquid solder inside the soldering furnace 400 to provide the temperature of the molten mixture for the accommodating cavity 101 through heat conduction, which is beneficial to the subsequent separation process of solder dross and solder. The solder discharge port 104 is located at the bottom of the separation main body 100 and is used to discharge the processed solder from the separation main body 100, facilitating subsequent processing or recycling.

[0109] According to an embodiment of the present invention, the separation mechanism 300 includes a stirring and separating component 310, a first transmission component 320, and a driving motor 330. At least part of the stirring and separating component 310 is arranged in the accommodating cavity 101. The output shaft of the driving motor 330 drives the stirring and separating component 310 to rotate through the first transmission component 320, and the driving motor 330 is arranged outside the soldering furnace 400.

[0110] It can be understood that the stirring and separating component 310 is a component that stirs and separates the dregs during the process of separating solder dross. At least part of it is arranged in the accommodating cavity 101 to ensure that the mixture can be fully stirred and separated during the separation process.

[0111] The driving motor 330 is arranged outside the soldering furnace 400, avoiding the motor being directly exposed to high temperature and corrosive environments, extending the service life of the driving motor 330, and facilitating maintenance and repair. At the same time, it reduces the overall height of the device, does not interfere with adding new mixture to the separation main body 100, and is convenient to use.

[0112] It should be noted that the first transmission component 320 can be any existing transmission component, such as a gear or a chain, and no specific limitation is made here.

[0113] According to an embodiment of the present invention, the stirring and separating component 310 includes a rotating shaft 311 and a spiral blade 312. The spiral blade 312 is wound around the rotating shaft 311, and the driving motor 330 is adapted to drive the rotating shaft 311 to rotate. It can be understood that the spiral blade 312 can effectively stir the mixture. By driving the spiral blade 312 to rotate through the rotating shaft 311, the mixture can be more evenly distributed during the stirring process, which is beneficial to separating the target substance and improving the separation accuracy.

[0114] According to an embodiment of the present invention, the accommodating cavity 101 is in a funnel shape, and the stirring and separating component 310 is disposed at the center of the accommodating cavity 101. It can be understood that the funnel-shaped design of the accommodating cavity 101 can make the mixture more evenly distributed inside. The stirring and separating component 310 is located at the center of the accommodating cavity 101, which can ensure that the mixture is fully mixed and separated during the stirring process, improving the processing efficiency and accuracy.

[0115] In one embodiment, the separation mechanism 300 includes a rotating barrel, a first transmission component 320, and a driving motor 330. At least a part of the rotating barrel is located in the accommodating cavity 101. The output shaft of the driving motor 330 drives the rotating barrel to rotate through the first transmission component 320. The rotating barrel is connected up and down and can rotate relative to the accommodating cavity 101. The mixture is placed in the rotating barrel and is adapted to rotate with the rotating barrel to centrifugally separate the solder dross and the solder. The separated solder enters the accommodating cavity 101 through the outlet below the rotating barrel and then leaves the separation main body 100 from the solder outlet 104.

[0116] According to an embodiment of the present invention, the first transmission component 320 is a chain. The output shaft of the driving motor 330 is provided with a first gear 340, and the stirring and separating component 310 is provided with a second gear 350. The chain is connected between the first gear 340 and the second gear 350. It can be understood that the chain can effectively transmit the output rotational force of the driving motor 330 to the stirring and separating component 310, usually maintaining a stable operation during work, reducing vibration and noise, and having strong wear resistance at the same time.

[0117] According to an embodiment of the present invention, the separation mechanism 300 further includes a housing 700, and the housing 700 covers the first transmission component 320 and the driving motor 330. It can be understood that the housing 700 and the housing cover can effectively protect the first transmission component 320 and the driving motor 330, prevent external substances such as dust and water vapor from invading, reduce the risk of mechanical structure damage, and improve the use safety.

[0118] According to an embodiment of the present utility model, the dross separation system further includes a lifting device 800. Please refer to Figure 2 , the lifting device 800 includes a fixed seat 810 and a movable member 820. The fixed seat 810 is fixedly installed on the soldering furnace 400. The movable member 820 is adapted to slide along the height direction of the soldering furnace 400 and is fixedly connected to the fixed seat 810. The separation main body 100 is connected to the movable member 820.

[0119] It can be understood that through the design of the lifting device 800, the height adjustment of the separation main body 100 in the vertical direction can be realized, so that the height can be adjusted according to the liquid level of the soldering furnace 400, ensuring that at least part of the separation main body 100 is located below the solder liquid level in the solder space 401 during the dross separation process.

[0120] It should be noted that as the dross is continuously recycled, the liquid level height of the solder in the solder space 401 may rise. The height of the separation main body 100 can be adjusted through the lifting device 800 to prevent the liquid level from exceeding the height of the accommodating cavity 101 and reducing the separation efficiency. At the same time, if the operator is also using the solder in the solder space 401 during the recycling process and the solder liquid level in the soldering furnace 400 continuously drops, the height of the separation main body 100 can be adjusted through the lifting device 800 to prevent the solder liquid level from being too low and reducing the heat conduction speed.

[0121] It should be noted that the sliding and fixed connection of the movable member 820 to the fixed seat 810 can be realized by an existing lifting device, and no specific limitation is made here. For example, the movable member 820 and the fixed seat 810 are slidably and fixedly connected through a lifting screw rod. When the lifting screw rod rotates forward, the movable member 820 is driven to rise relative to the fixed seat 810. When the lifting screw rod rotates reversely, the movable member 820 is driven to descend relative to the fixed seat 810.

[0122] In an embodiment, the dross separation system further includes an auxiliary heating device, and the auxiliary heating device is adapted to provide heat for the separation main body 100.

[0123] When the solder liquid level in the solder space 401 drops, the auxiliary heating device can provide heat for the separation main body 100 to prevent the heat inside the separation main body 100 from being insufficient due to the too low solder liquid level and resulting in a slow liquefaction speed of the mixture.

[0124] Next, a specific embodiment is used to describe the working process of the auxiliary heating device of the present application:

[0125] When the separation main body 100 is fixedly connected to the soldering furnace 400, the solder liquid level in the solder space 401 has a preset minimum liquid level. When the height of the actual liquid level is lower than the height of the minimum liquid level, the auxiliary heating device is started to assist in heating the separation main body 100.

[0126] It should be noted that the separation main body 100 of the embodiment here is fixedly connected to the tin furnace 400, while the separation main body 100 of the present application can also be adjusted in the height direction relative to the tin furnace 400 through the lifting device 800, and the auxiliary heating device can be used in cooperation with the lifting device 800.

[0127] According to an embodiment of the present invention, the solder dross separation system further includes a grinding mechanism 200. The grinding mechanism 200 is installed on the tin furnace 400. The grinding mechanism 200 includes a grinding component 210 and a feed hopper 220. The grinding component 210 is used for pulverizing the mixture entering the feed hopper 220, and the outlet of the feed hopper 220 is communicated with the inlet 102.

[0128] It can be understood that the grinding component 210 is used for pulverizing and grinding the mixture entering the feed hopper 220, so as to better perform the subsequent separation work, improving the separation efficiency and quality. The feed hopper 220 is used for accommodating the mixture and conveying it to the grinding component 210 for processing. The outlet of the feed hopper 220 is communicated with the inlet 102 to ensure that the ground material smoothly enters the next processing stage, ensuring the continuity and high efficiency of the production process.

[0129] According to an embodiment of the present invention, the feed hopper 220 is arranged above the accommodation chamber 101, and the grinding component 210 is connected to the separation mechanism 300. It can be understood that the feed hopper 220 is arranged above the accommodation chamber 101, so that the ground mixture can more easily enter the grinding component 210 under the action of gravity, improving the conveying efficiency. The grinding component 210 is connected to the separation mechanism 300, which helps the coordinated operation between the two components, improving the processing efficiency and quality.

[0130] In one embodiment, the feed hopper 220 is funnel-shaped. Of course, the feed hopper 220 can be of other shapes, and no specific limitation is made here.

[0131] In one embodiment, the rotation centers of the grinding component 210 and the stirring and separating component 310 are coaxial. Specifically, the grinding component 210 and the stirring and separating component 310 are integrally formed, or the grinding component 210 is fixedly connected to the stirring and separating component 310.

[0132] It can be understood that by making the rotation centers of the grinding component 210 and the stirring and separating component 310 coaxial, the grinding component 210 and the stirring and separating component 310 can be driven by the same driving motor 330, which can improve the compactness of the system.

[0133] The welding equipment according to the embodiment of the present invention includes the above-mentioned solder dross separation system.

[0134] It can be understood that the dross separation system can improve the utilization rate of the dross by the soldering equipment, effectively recycle and process the waste dross generated during the soldering process, and achieve the reuse of resources and environmental protection.

[0135] It should be noted that since the soldering equipment of the present utility model includes the above-mentioned dross separation system, it has all the technical effects of the above-mentioned dross separation system, which will not be elaborated here.

[0136] The soldering work of the soldering equipment and the recycling work of the dross separation system can be carried out synchronously or asynchronously, and no specific restrictions are imposed here.

[0137] In one embodiment, the soldering equipment further includes a detection component for real-time detection of the solder level in the solder space 401. It can be understood that through the detection component, the system can monitor the height and state of the solder level in real time. This can timely detect the change of the liquid level, keep the solder level at an appropriate position, ensure the welding quality and stability, and at the same time ensure the stable recycling of the solder by the dross separation system, so as to ensure that the soldering work of the soldering equipment and the recycling work of the dross separation system can be carried out synchronously.

[0138] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model and should all be covered by the scope of the claims of the present utility model.
