In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
[0080] In the related art, the oxidation rate of tin material in the wave soldering machine is high, which produces a lot of tin slag, causing waste, and a lot of tin slag is formed in the tin furnace 600, affecting the welding quality.
[0081] The present invention provides a wave soldering machine according to one aspect of the present invention. Figure 11-13 As shown, it includes a wave soldering device 4, a tin adding device 5 and a tin slag separation device 6. The wave soldering device 4 includes a tin furnace 600. The tin furnace 600 is formed with a tin cavity for accommodating liquid tin. The tin adding device 5 is connected to the tin furnace 600 and is suitable for supplying tin material into the tin furnace 600 based on the liquid level height of the tin furnace 600. The tin slag separation device 6 is installed in the tin furnace 600 and is used to separate the tin slag from the liquid tin. The tin slag separation device 6 is provided with a tin liquid outlet 613 and a tin slag outlet 612. The tin liquid outlet 613 is connected to the tin cavity, and the tin slag outlet 612 is connected to the outside of the tin furnace 600. The separated tin liquid flows into the tin cavity through the tin material outlet, and the separated tin slag is discharged through the tin slag outlet 612.
[0082] Tin slag is the solid or semi-solid residue of tin oxide and other impurities formed during the welding process. Tin slag is usually produced by the contact of tin liquid with oxygen in the air during welding, or due to the impurity of welding materials. The presence of tin slag can easily lead to a decline in welding quality, such as uneven welds, oxide layers, poor solder joints and other problems.
[0083] In an optional embodiment, the wave soldering machine also includes a casing 1, and the casing 1 forms an installation cavity. The wave soldering device 4 can be arranged in the installation cavity. In this embodiment, the casing 1 is the outer shell 67 of the wave soldering machine, in which an installation cavity is formed for installing other accessories. The tin furnace 600 is a device for heating and storing tin material. A tin cavity for containing molten tin is formed inside the tin furnace 600, and the tin material in the tin furnace 600 is in liquid state.
[0084] It should be noted that when the liquid level of the tin furnace 600 is low, the height of the tin liquid from the circuit board above will increase, resulting in an increase in the distance the tin liquid sprays and falls, thereby increasing the time the tin liquid is in contact with the air, which will make the tin liquid more easily oxidized and produce more tin slag during the welding process.
[0085] In this embodiment, the tin adding device 5 can be connected to the tin furnace 600 to add tin material into the tin furnace 600 according to the liquid level height in the tin furnace 600, so that the liquid level in the tin furnace 600 is maintained at an appropriate height, thereby reducing the contact time between the tin liquid and the air, thereby reducing the oxidation of the tin liquid, and thus reducing the generation of tin slag.
[0086] Even if the liquid level in the tin furnace 600 is maintained at a certain height, when there is tin slag mixed with tin liquid in the tin furnace 600, the tin slag may contain oxidants, such as oxygen or moisture, which will accelerate the oxidation reaction when in contact with the tin liquid. If the tin slag accumulates in the tin furnace 600 for a long time, the oxidants therein will continue to exist, increasing the possibility of oxidation of the tin liquid. Some tin slag may contain impurities or pollutants, which will accelerate the oxidation of the tin liquid. Long-term accumulation of tin slag will increase the contact time and opportunity of these pollutants with the tin liquid, further promoting the oxidation of the tin material.
[0087] Therefore, in addition to providing a tin adding device 5 to automatically add tin to the tin furnace 600, this embodiment also provides a tin slag separation device 6 to separate the tin slag from the tin liquid in the tin furnace 600. The separated tin liquid continues to enter the tin furnace 600 for recycling, saving raw materials. The separated tin slag is discharged to the outside of the tin furnace 600, which helps to keep the inside of the tin furnace 600 clean and avoid the influence of the tin slag on the oxidation of the tin liquid in the tin furnace 600.
[0088] During the soldering process, the tin adding device 5 and the tin slag separation device 6 operate simultaneously. The tin adding device 5 is responsible for supplying tin wire, while the tin slag separation device 6 is responsible for collecting and processing the tin slag produced by soldering. The two cooperate with each other to maintain the liquid level of the tin furnace 600, while keeping the tin furnace 600 clean, reducing the oxidation rate of the tin material, and ensuring the normal operation of the wave soldering machine.
[0089] In an alternative embodiment, reference Fig.12 and Fig.13As shown, the tin slag separation device 6 includes a tin slag collection box 64, a separation body 61 and a separation mechanism 63. A tin cavity is formed inside the tin furnace 600; the tin slag collection box 64 is connected to the tin furnace 600, and a tin slag space 641 is formed inside the tin furnace 600, and the tin slag space 641 and the tin cavity are independent of each other; the separation body 61 is provided with an inlet 611, a tin slag outlet 612 and a tin liquid outlet 613, the tin slag outlet 612 is connected to the tin slag space 641, and the tin liquid outlet 613 is connected to the tin cavity; the separation mechanism 63 is used to drive the mixture of tin slag and tin liquid to centrifugally rotate to achieve tin slag separation; during the tin slag separation process, the separation body 61 is at least partially located below the solder liquid level of the tin cavity, so that the solder in the tin cavity heats the containing cavity, the separated solder enters the tin cavity through the solder outlet, and the separated tin slag enters the tin slag space 641 through the tin slag outlet 612.
[0090] According to the tin slag separation device 6 of the utility model embodiment, refer to Fig.12 and Fig.13 As shown, through the centrifugal rotation of the separation mechanism 63 and the heat energy supply of the tin furnace 600, the tin slag separation device 6 can efficiently separate the solder and tin slag in the waste solder tin slag. During the tin slag separation process, the separation body 61 is at least partially below the solder liquid level of the tin furnace 600. The tin furnace 600 can provide sufficient heat for the separation body 61 so that the mixture can be fully liquefied to ensure smooth separation of the tin slag. The centrifugal rotation of the separation mechanism 63 allows the solder and tin slag with different densities to leave the accommodation cavity from the tin slag outlet 612 and the tin liquid outlet 613 respectively under the action of centrifugal force.
[0091] It is understandable that a tin cavity is formed inside the tin furnace 600, wherein the solder stored in the tin cavity can be used as a raw material for welding. The tin furnace 600 can provide thermal energy to heat the mixture in the accommodating cavity, which can promote the tin slag separation process. It should be noted that the tin slag separation process here can be understood as the separation of reusable solder and non-reusable tin slag, and entering different storage spaces (tin slag space 641 and tin cavity) from different discharge ports (tin slag outlet 612 and tin liquid outlet 613).
[0092] It can be understood that the tin slag space 641 of the tin slag collection box 64 and the tin chamber of the tin furnace 600 are independent of each other. The separated solder enters the tin chamber through the tin liquid outlet 613 for collection, while the separated tin slag enters the tin slag space 641 through the tin slag outlet 612, which is convenient for the operator to recycle the solder after the tin slag is separated, and to deal with the tin slag after the tin slag is separated.
[0093] It can be understood that the separation mechanism 63 can drive the mixture of tin slag and tin liquid to rotate, so that the tin slag and solder with different densities are separated. The tin slag with low density floats above the solder and enters the tin slag space 641 from the tin slag outlet 612 under the action of centrifugal force.
[0094] In an optional embodiment, a containing cavity is formed inside the separation body 61 , and the separation body 61 is provided with a feed inlet 611 connected to the containing cavity, a tin slag outlet 612 and a tin liquid outlet 613 , and the tin liquid outlet 613 is provided below the tin slag outlet 612 .
[0095] According to the tin slag separation device 6 of the embodiment of the utility model, the grinding part 621 of the grinding mechanism 62 can pulverize the mixture, which helps to improve the efficiency and accuracy of the subsequent separation process. The separation mechanism 63 can drive the mixture in the accommodating chamber to rotate centrifugally, realize the intelligent separation of tin slag, and improve the degree of automation and production efficiency. The separation body 61 is provided with a feed inlet 611, a tin slag outlet 612 and a tin liquid outlet 613, which is convenient for recycling the solder and removing the tin slag that cannot be recycled. The tin slag outlet 612 and the tin liquid outlet 613 are respectively arranged at different positions, which helps to reduce the possibility of them being mixed together and maintain the purity of the solder and the tin slag.
[0096] According to one embodiment of the present invention, referring to Fig.12 and Fig.13 As shown, the tin slag separation device 6 also includes a fixed support frame 65, and the fixed support frame 65 is used to fix the separation body 61 to the inner wall of the tin furnace 600.
[0097] It can be understood that the fixed support frame 65 can firmly fix the separation body 61 on the inner wall of the tin furnace 600 to prevent it from moving or shaking during operation, thereby ensuring the stability and reliability of the separation process.
[0098] It is understandable that the fixed support frame 65 only needs to fix the separation body 61 to the inner wall of the tin furnace 600. The fixed support frame 65 can be connected to the inner wall of the tin furnace 600, or to the outer surface of the tin furnace 600, or can be hung on the edge of the tin furnace 600.
[0099] According to one embodiment of the present invention, referring to Fig.12 and Fig.13 As shown, the fixed support frame 65 is a U-shaped frame, which is arranged around the outer contour of the separation body 61 , and the end of the U-shaped frame is fixed to the inner wall of the tin furnace 600 .
[0100] It can be understood that the shape design of the U-shaped frame enables it to completely surround the outer contour of the separation body 61, provide comprehensive support, effectively enhance the stability of the fixed support frame 65, and ensure a firm connection between the support frame 910 and the tin furnace 600.
[0101] Specifically, the end of the U-shaped frame can be fixed to the tin furnace 600 by screws.
[0102] According to one embodiment of the present invention, referring to Fig.12 and Fig.13 As shown, the separation mechanism 63 includes a stirring and separating component 631 , a transmission component 632 and a driving motor 633 . The output shaft of the driving motor 633 drives the stirring and separating component 631 to rotate through the transmission component 632 . The driving motor 633 is arranged outside the tin furnace 600 .
[0103] It can be understood that the stirring and separating component 631 is a component for stirring and separating slag during the tin slag separation process, ensuring that the mixture can be fully stirred and separated during the separation process.
[0104] The drive motor 633 is arranged outside the tin furnace 600, which prevents the motor from being directly exposed to high temperature and corrosive environment, prolongs the service life of the drive motor 633, and facilitates maintenance. At the same time, the height of the whole device is reduced, which will not hinder the addition of new mixture to the separation body 61, and is convenient for use.
[0105] It should be noted that the transmission component 632 can be any existing transmission component 632, such as a gear or a chain, and no specific limitation is made here.
[0106] According to one embodiment of the present invention, referring to Fig.12 and Fig.13 As shown, the stirring and separating component 631 includes a rotating shaft 6311 and a spiral blade 6312, the spiral blade 6312 is arranged around the rotating shaft 6311, and the driving motor 633 is suitable for driving the rotating shaft 6311 to rotate. It can be understood that the spiral blade 6312 can effectively stir the mixture, and the spiral blade 6312 is driven to rotate by the rotating shaft 6311, so that the mixture can be more evenly distributed during the stirring process, which is conducive to separating the target substance and improving the separation accuracy.
[0107] In one embodiment, the separation mechanism 63 includes a rotating barrel, a transmission component 632 and a drive motor 633. The rotating barrel is at least partially located in the accommodating chamber, and the output shaft of the drive motor 633 drives the rotating barrel to rotate through the transmission component 632. The rotating barrel is connected up and down and can rotate. The mixture is placed in the rotating barrel, which is suitable for centrifugally separating the tin slag and the solder as the rotating barrel rotates. The separated solder enters the accommodating chamber through the outlet below the rotating barrel and then leaves the separation body 61 from the tin liquid outlet 613.
[0108] According to an embodiment of the present invention, the transmission component 632 is a chain, the output shaft of the driving motor 633 is provided with a first gear 634, the stirring and separating component 631 is provided with a second gear 635, and the chain is connected to the first gear 634 and the second gear 635. It can be understood that the chain can effectively transmit the output rotational force of the driving motor 633 to the stirring and separating component 631, and can usually maintain stable operation during operation, reduce vibration and noise, and have strong wear resistance.
[0109] According to one embodiment of the present invention, referring to Fig.12 and Fig.13 As shown, the separation mechanism 63 further includes a housing 67, and the housing 67 covers the transmission component 632 and the drive motor 633. It can be understood that the housing 67 and the housing 67 cover can effectively protect the transmission component 632 and the drive motor 633, prevent the intrusion of external substances such as dust and water vapor, reduce the risk of damage to the mechanical structure, and improve the safety of use.
[0110] According to an embodiment of the present invention, the tin slag separation device 6 further includes a lifting device 68, see Figure 2 The lifting device 68 includes a fixed frame 681 and a movable member 682. The fixed frame 681 is fixedly installed on the tin furnace 600. The movable member 682 is suitable for sliding along the height direction of the tin furnace 600 and is fixedly connected to the fixed frame 681. The separation body 61 is connected to the movable member 682.
[0111] It can be understood that through the design of the lifting device 68, the height adjustment of the separation body 61 in the vertical direction can be realized, so that the height can be adjusted according to the liquid level of the tin furnace 600, ensuring that during the separation of the tin slag, the separation body 61 is at least partially located below the solder liquid level in the tin chamber.
[0112] It should be noted that, as the tin slag is continuously recycled, the liquid level of the solder in the tin chamber may rise, and the height of the separation body 61 can be adjusted by the lifting device 68 to prevent the liquid level from exceeding the height of the accommodation chamber, resulting in a decrease in separation efficiency. At the same time, if the operator is also using the solder in the tin chamber during the recycling process, the solder liquid level in the tin furnace 600 continues to drop, and the height of the separation body 61 can be adjusted by the lifting device 68 to prevent the solder liquid level from being too low, resulting in a decrease in the speed of heat conduction.
[0113] It should be noted that the sliding and fixed connection of the movable part 682 to the fixed frame 681 can be achieved through the existing lifting device 68, and no specific limitation is made here. For example, the movable part 682 and the fixed frame 681 are slidably and fixedly connected through the lifting screw rod 920. The lifting screw rod 920 rotates forward to drive the movable part 682 to rise relative to the fixed frame 681, and the lifting screw rod 920 rotates reversely to drive the movable part 682 to descend relative to the fixed frame 681.
[0114] In one embodiment, the tin slag separation device 6 further includes an auxiliary heating device, which is suitable for providing heat to the separation body 61 .
[0115] When the solder liquid level in the tin cavity drops, the auxiliary heating device can provide heat to the separation body 61 to avoid insufficient heat inside the separation body 61 due to the solder liquid level being too low, resulting in slow liquefaction of the mixture.
[0116] The working process of the auxiliary heating device of the present application is described below in conjunction with a specific embodiment:
[0117] When the separation body 61 is fixedly connected to the tin furnace 600 , the solder liquid level in the tin cavity has a preset minimum liquid level. When the actual liquid level is lower than the minimum liquid level, the auxiliary heating device is started to assist in heating the separation body 61 .
[0118] It should be noted that the separation body 61 of the embodiment here is fixedly connected to the tin furnace 600, and the separation body 61 of the present application can also be adjusted in height relative to the tin furnace 600 through the lifting device 68, and the auxiliary heating device can be used in conjunction with the lifting device 68.
[0119] According to one embodiment of the present invention, referring to Fig.12 and Fig.13 As shown, the tin slag separation device 6 also includes a grinding mechanism 62, which is installed on the tin furnace 600. The grinding mechanism 62 includes a grinding component 621 and a feed barrel 622. The grinding component 621 is used to crush the mixture entering the feed barrel 622. The outlet of the feed barrel 622 is connected to the feed port 611.
[0120] It is understandable that the grinding component 621 is used to crush and grind the mixture entering the feed barrel 622, so as to better perform the subsequent separation work and improve the separation efficiency and quality. The feed barrel 622 is used to hold the mixture and transport it to the grinding component 621 for processing. The outlet of the feed barrel 622 is connected to the feed inlet 611, ensuring that the ground material smoothly enters the next processing stage, ensuring the continuity and efficiency of the production process.
[0121] According to one embodiment of the present invention, referring to Fig.12 and Fig.13 As shown, the feed barrel 622 is arranged above the receiving chamber of the separation body, and the grinding component 621 is connected to the separation mechanism 63. It can be understood that the feed barrel 622 is arranged above the receiving chamber, so that the ground mixture can enter the grinding component 621 more easily by gravity, thereby improving the conveying efficiency. The grinding component 621 is connected to the separation mechanism 63, which facilitates the coordinated operation between the two components and improves the processing efficiency and quality.
[0122] In one embodiment, the feed bucket 622 is funnel-shaped. Of course, the feed bucket 622 can be in other shapes, which are not specifically limited here.
[0123] In one embodiment, the rotation centers of the grinding component 621 and the stirring and separating component 631 are coaxial. Specifically, the grinding component 621 and the stirring and separating component 631 are integrally formed, or the grinding component 621 is fixedly connected to the stirring and separating component 631 .
[0124] It can be understood that, by having the grinding component 621 and the stirring and separating component 631 have coaxial rotation centers, the grinding component 621 and the stirring and separating component 631 can be driven by the same driving motor 633, which can improve the compactness of the system.
[0125] According to one embodiment of the utility model, the tin adding device 5 includes a detection component and a controller (not shown in the figure). The detection component is arranged in the tin furnace 600, and is used to detect the liquid level height of the tin furnace 600 and the tin slag content in the tin chamber. The controller is electrically connected to the detection component, the tin adding device 5 and the tin slag separation device 6 to control the operation of the tin adding device 5 and the tin slag separation device 6 based on the liquid level height of the tin furnace 600 and the tin slag content in the tin chamber.
[0126] It can be understood that in this embodiment, through sensors or other detection equipment, the detection component can accurately sense the liquid level of the tin liquid and the content of tin slag in the tin furnace 600, and transmit these data to the controller. The controller performs logical judgment and control based on the liquid level and tin slag content data of the tin furnace 600 obtained from the detection component. When the liquid level in the tin furnace 600 is lower than the set value, the controller will start the tin adding device 5 to replenish the tin liquid to maintain the continuity of the welding process. At the same time, when the tin slag content in the tin chamber reaches a certain level, the controller will start the tin slag separation device 6 to effectively separate the tin slag from the tin liquid to ensure the quality and stability of the welding process.
[0127] The controller continuously monitors the liquid level and tin slag content of the tin furnace 600, and adjusts the working state of the tin adding device 5 and the tin slag separating device 6 in real time to meet the requirements of the welding process. When the tin liquid is insufficient, the tin adding device 5 will be started to add an appropriate amount of tin wire into the tin furnace 600. At the same time, when too much tin slag accumulates, the tin slag separating device 6 will be started to separate the tin slag from the tin liquid to ensure the stability and continuity of the welding process. Through such a setting, the welding process can be automatically controlled, which improves production efficiency and product quality, and also reduces the need for manual intervention.
[0128] Exemplarily, the controller can also control parameters such as the working time and working frequency of the tin adding device 5 and the tin slag separation device 6 to adapt to the needs of liquid level changes during welding, maintain a reasonable level of tin slag, avoid affecting the welding process, and improve production efficiency and welding quality.
[0129] According to one embodiment of the present invention, referring to Figure 11-13 As shown, the tin adding device 5 includes a material box 51 and a tin feeding tube 52. The material box 51 is used to place the tin wire. The first end of the tin feeding tube 52 is connected to the material box 51, and the second end of the tin feeding tube 52 is arranged in the tin cavity. The tin wire is suitable for entering the tin furnace 600 through the tin feeding tube 52. The second end of the tin feeding tube 52 is arranged below the tin liquid outlet 613, and the second end of the tin feeding tube 52 is located below the liquid level of the tin cavity.
[0130] It can be understood that, in this embodiment, the material box 51 is used to store tin wire, and the tin feeding tube 52 is used to transport the tin wire to the welding equipment. The tin wire passes through the first end and the second end of the tin feeding tube 52 and enters the tin cavity of the tin furnace 600. The tin feeding tube 52 guides the tin wire during the feeding process to ensure that the tin wire can be smoothly transported to the tin cavity of the welding setting to ensure that the tin wire will not be blocked or stuck during the transportation process, thereby ensuring the continuity and stability of the welding process.
[0131] Furthermore, the second end of the tin delivery tube 52 can be arranged below the tin liquid outlet 613. Such an arrangement can utilize the higher temperature tin liquid at the tin liquid outlet 613 to quickly melt the tin wire into liquid, thereby achieving a smoother and more efficient tinning process. In this way, the melting speed of the tin wire can be accelerated, the waiting time can be reduced, and the efficiency and production speed of tinning can be improved. Exemplarily, the second end of the tin delivery tube 52 can be arranged below the liquid surface of the tin furnace 600 to facilitate the melting of the tin wire from solid to liquid.
[0132] In an alternative embodiment, reference Fig.14 and Fig.15As shown, a base 511, a guide wheel 512 and an adjusting portion 513 are provided in the material box 51, and the guide wheel 512 is rotatably connected to the base 511; the adjusting portion 513 is rotatably connected to the base 511, and a clamping wheel 5131 is provided on the adjusting portion 513; a guide channel 5121 for the tin wire is formed between the clamping wheel 5131 and the guide wheel 512; the adjusting portion 513 rotates relative to the base 511, so that the clamping wheel 5131 approaches or moves away from the guide wheel 512.
[0133] It can be understood that the clamping wheel 5131 is away from the guide wheel 512, which makes it convenient for the tin wire to pass through the guide channel 5121. The clamping wheel 5131 is close to the guide wheel 512 to clamp the tin wire; the guide wheel 512 rotates to use friction to drive the transmission of the tin wire; the adjustment part 513 rotates relative to the base 511 to adjust the distance between the guide wheel 512 and the clamping wheel 5131, which can be suitable for tin wires of different diameters and has high flexibility.
[0134] In the related art, since the friction between the guide wheel 512 and the tin wire is required to achieve the effect of transmitting the tin wire during the welding process, the distance between the two guide wheels 512 is very close, and the tin wire is difficult to install between the two guide wheels 512. However, the embodiment of the utility model clamps the tin wire through the guide wheel 512 and the movable clamping wheel 5131, which can drive the transmission of the tin wire while supporting the tin wire; the separation and combination of the guide wheel 512 and the clamping wheel 5131 is not only conducive to the installation of the tin wire, but also the guide channel 5121 can be adjusted to a suitable width. If the width of the guide channel 5121 is too small, it will increase the resistance of the tinning process. If the width of the guide channel 5121 is too large, it will cause the guide wheel 512 to idle; in addition, the width of the guide channel 5121 is adjustable, which is conducive to adapting to tin wires of different sizes.
[0135] It is understandable that when installing the tin wire, the adjusting part 513 can be rotated to move the clamping wheel 5131 away, which is convenient for installing the tin wire; if a guide rail is directly set on the base 511, and the adjusting part 513 is installed on the guide rail, the clamping wheel 5131 is moved close to or away from the guide wheel 512 through the linear movement of the adjusting part 513 on the guide rail, then the guide rail needs to be processed on the base 511, and space for the guide rail needs to be reserved on the base 511, resulting in a large overall volume. In the embodiment of the utility model, the adjusting part 513 is directly hinged on the base 511, and there is no need to perform excessive processing on the base 511; in the process of installing the tin wire, the adjusting part 513 can be rotated to rotate the clamping wheel 5131 outside the base 511, which is conducive to miniaturizing the tinning device 5 while meeting the transmission requirements of the tin wire, reducing the material of the base 511, and thus reducing the production cost.
[0136] It is understandable that in order to ensure that the width of the guide channel 5121 is relatively fixed and the clamping wheel 5131 is maintained at a specific position in the absence of a large external force, the adjustment part 513 can have its own damping. While realizing the rotation of the adjustment part 513, the relative position between the clamping wheel 5131 and the guide wheel 512 is kept fixed by using the resistance of the damping, so that the transmission of the tin wire can proceed smoothly. The adjustment part 513 can be hinged to the base 511 through a pin shaft, and friction materials such as rubber gaskets can be added between the pin shaft and the shaft hole of the adjustment part 513 to improve the damping effect.
[0137] See also Fig.14 In one embodiment, the tinning device 5 further includes a locking assembly 514, which is suitable for fixing the adjusting portion 513. The tin wire is passed through the guide channel 5121, and the adjusting portion 513 is rotated. The locking assembly 514 fixes the pressing wheel 5131 to a suitable position to prevent the pressing wheel 5131 from shifting during operation, thereby ensuring the normal operation of the tin wire transmission.
[0138] See also Fig.14 In one embodiment, the locking assembly 514 includes a locking rod 5141, and the adjustment part 513 is provided with two, namely a first adjustment part 5132 and a second adjustment part 5133; the first end of the locking rod 5141 is rotatably connected to the first adjustment part 5132, and the second end of the locking rod 5141 is suitable for fixing or disengaging from the second adjustment part 5133; the relative movement between the first adjustment part 5132 and the second adjustment part 5133 is limited by the locking rod 5141 to fix the first adjustment part 5132 and the second adjustment part 5133.
[0139] It can be understood that the first adjustment portion 5132 and the second adjustment portion 5133 are rotatably connected to the base 511 respectively, and the first adjustment portion 5132 and the second adjustment portion 5133 are connected by the locking rod 5141 to limit the relative movement between the first adjustment portion 5132 and the second adjustment portion 5133, so that the clamping wheel 5131 is maintained at a specific position, thereby ensuring that the width of the guide channel 5121 is appropriate and improving the stability of the tin feeding process; the first adjustment portion 5132 and the second adjustment portion 5133 can be fixed or detached by the second end of the locking rod 5141, and the fixing of the first adjustment portion 5132 and the second adjustment portion 5133 can be achieved, without the need to fix the first adjustment portion 5132 and the second adjustment portion 5133 separately, thereby reducing the operation flow The tin wire is transmitted in the guide channel 5121 and is simultaneously acted upon by the first adjusting portion 5132 and the second adjusting portion 5133. The position of the guide wheel 512 is fixed, and the first adjusting portion 5132 and the second adjusting portion 5133 are synchronously fixed by a locking rod 5141. The distance between the first adjusting portion 5132 and the guide wheel 512 and the distance between the second adjusting portion 5133 and the guide wheel 512 can be synchronously adjusted, thereby reducing the difference in the force exerted on the tin wire by the first adjusting portion 5132 and the second adjusting portion 5133, so that the force exerted on the tin wire during the transmission process is relatively uniform, which is beneficial to reducing the deviation during the tin feeding process and improving the stability of the tin wire transmission process.
[0140] It can be understood that the first end of the locking rod 5141 is rotatably connected to the first adjustment portion 5132, and two connecting ears 5135 can be set on the side of the first adjustment portion 5132 close to the locking rod 5141, and the locking rod 5141 is connected between the two connecting ears 5135; the two connecting ears 5135 can further support the locking rod 5141, improve the reliability of the connection, and prevent the locking rod 5141 from loosening during rotation; the first adjustment portion 5132 is hinged to the locking rod 5141 through the two connecting ears 5135, which can increase the rotation angle range of the locking rod 5141 and improve the rotation flexibility of the locking rod 5141.
[0141] In one embodiment, a locking rod 5141 may be corresponding to fixing one adjusting portion 513. For example, one end of the locking rod 5141 is rotatably connected to the base 511, and the other end of the locking member is provided with a locking portion 5140. The locking portion 5140 is suitable for fixing or disengaging the adjusting portion 513. The adjusting portion 513 is hinged on the base 511, and the base 511 and the adjusting portion 513 are connected by the locking rod 5141, so as to limit the movement of the adjusting portion 513, and then maintain the clamping wheel 5131 of the adjusting portion 513 at a specific position to ensure the normal tin feeding work.
[0142] In one embodiment, two guide wheels 512 can be provided, and the guide wheels 512 correspond to the adjustment parts 513 one by one; providing two guide wheels 512 can provide more stable support for the tin wire, prevent the tin wire from falling off and affecting the welding work; secondly, the two guide wheels 512 can better maintain the transmission path of the tin wire, prevent the tin wire from being offset or twisted during the transmission process, affecting the tin feeding effect, and make the transmission of the tin wire more stable.
[0143] See also Fig.14 In one embodiment, the tin adding device 5 includes a driving member 5153, and the output shaft of the driving member 5153 is fixedly connected to the guide wheel 512; the guide wheel 512 is driven to rotate by the driving member 5153, thereby promoting the tin feeding work; generally, the driving member 5153 is a motor; two driving members 5153 can be provided, and the two driving members 5153 respectively drive the two guide wheels 512 to rotate to achieve dual drive. If one of the driving members 5153 fails, the operation of the device can be maintained by relying on the other driving member 5153, which can improve the reliability and stability of the tin adding device 5 and reduce the occurrence of accidents; in addition, the setting of two driving members 5153 can increase the overall tin feeding speed, balance the load of the two guide wheels 512, and improve work efficiency.
[0144] See also Fig.14 In one embodiment, the tin adding device 5 also includes a third sensor 5154, which is arranged between the two guide wheels 512, the third sensor 5154 is located on one side of the guide channel 5121 and the third sensor 5154 is suitable for detecting the presence of tin wire; the third sensor 5154 is arranged to detect the presence of tin wire by the third sensor 5154, so as to judge whether the tin feeding work is carried out normally; generally, the third sensor 5154 is a photoelectric sensor, and if the third sensor 5154 does not detect the tin wire, it is judged that the tin wire is out of the tin adding device 5 or the tin wire is exhausted.
[0145] See also Fig.14 In one embodiment, the tinning device 5 may further include a guide block 516, and the guide channel 5121 partially passes through the guide block 516 and the guide block 516 is located between the two guide wheels 512. The guide block 516 further supports and guides the tin wire to increase stability.
[0146] See also Fig.14In one embodiment, the guide block 516 includes at least two guide walls 5161, and the guide channel 5121 passes through the two guide walls 5161 in sequence; the guide block 516 is fixedly set on the base 511, and the tin wire is supported by the guide walls 5161; the setting of the two guide walls 5161 can improve the stability of the tin wire during the movement process, and further enhance the guiding effect. A detection space 5162 is formed between the two guide walls 5161, and the probe of the third sensor 5154 faces the detection space 5162. The two guide walls 5161 limit part of the tin wire in the detection space 5162, which is conducive to the third sensor 5154 to detect the tin wire located in the guide channel 5121, thereby improving the accuracy of the detection. Of course, a guide hole can also be directly opened on the guide block 516; the third sensor 5154 can also be set at one end of the guide block 516.
[0147] Of course, in other embodiments, a guide wheel 512 may also be provided, and the two adjustment parts 513 are respectively pressed on different positions of the guide wheel 512, so that the tin wire adheres to the surface of the guide wheel 512 for transmission, and the surface of the guide wheel 512 can provide support force for the tin wire.
[0148] See also Figure 14 to Figure 15 In one embodiment, the second adjustment portion 5133 is provided with a matching notch 5134 matching with the locking portion 5140 on a side facing the locking rod 5141 , and the second end of the locking rod 5141 is suitable for fixing or disengaging from the matching notch 5134 .
[0149] It can be understood that the second adjusting portion 5133 is provided with a matching notch 5134, which is conducive to the matching between the locking rod 5141 and the second adjusting portion 5133, making the operation simpler and more convenient; during the rotation of the locking rod 5141, the matching notch 5134 can approach the locking rod 5141 from the circumferential direction of the locking rod 5141 and match with the locking rod 5141; in order to prevent the second adjusting portion 5133 from falling off, the length of the second end of the locking rod 5141 can be appropriately extended in the setting. At the same time, the extended part of the second end of the locking rod 5141 can also be used as a hand-holding position during operation; if the locking rod 5141 is directly matched with the end direction of the locking rod 5141, the longer the locking rod 5141 is, the more difficult the matching is; and the second adjustment part 5133 of the embodiment of the utility model is matched with the locking rod 5141 from the circumferential direction of the locking rod 5141, extending the second end of the locking rod 5141 will not affect the matching between the locking rod 5141 and the second adjustment part 5133.
[0150] In order to achieve standardization of parts and reduce production costs and inventory pressure, the first adjustment portion 5132 and the second adjustment portion 5133 can adopt the same structure. For example, the matching notch 5134 can be formed between the two connecting ears 5135.
[0151] See also Fig.14 In one embodiment, the locking assembly 514 further includes an elastic member 5142, which is sleeved on the locking rod 5141 and abuts against the second adjustment portion 5133. The elastic force of the elastic member 5142 is suitable for adjusting the distance between the first adjustment portion 5132 and the second adjustment portion 5133. The tension is used to make the pressing wheel 5131 press the guide wheel 512 tightly, so as to achieve the clamping and transmission of the tin wire. Since the elastic member 5142 is elastic, the distance between the first adjustment portion 5132 and the second adjustment portion 5133 can fluctuate within a certain range. Therefore, the guide channel 5121 can accommodate tin wires within a certain diameter range, and has flexibility. When adjusting tin wires of different diameters, there is no need to replace different tinning devices 5, and the adaptability is wide. Generally, the elastic member 5142 is a spring.
[0152] See also Fig.14 In one embodiment, the pressure wheel 5131 of the first adjusting portion 5132 is disposed on a side close to the second adjusting portion 5133 , and the pressure wheel 5131 of the second adjusting portion 5133 is disposed on a side close to the first adjusting portion 5132 .
[0153] It can be understood that the pressing wheel 5131 of the first adjusting portion 5132 and the pressing wheel 5131 of the second adjusting portion 5133 are both arranged on the opposite side. In this way, when the distance between the first adjusting portion 5132 and the second adjusting portion 5133 is shortened, the pressing wheel 5131 of the first adjusting portion 5132 presses the first guide wheel 512, and the pressing wheel 5131 of the second adjusting portion 5133 presses the second guide wheel 512, so that the forces acting on the guide wheel 512 by the first adjusting portion 5132 and the second adjusting portion 5133 can be adjusted synchronously. For example, the elastic member 5142 is fixed to the second end of the locking rod 5141, and the elastic force of the elastic member 5142 is used to make the second adjusting portion 5133 approach the first adjusting portion 5132, so that the two pressing wheels 5131 press the guide wheel 512 at the same time. The elastic member 5142 may be fixed to the second end of the locking rod 5141 by welding or the like, or a limit block may be provided at the second end of the locking rod 5141 , and one end of the elastic member 5142 abuts against the limit block.
[0154] In other embodiments, the pressing wheel 5131 of the first adjusting portion 5132 is arranged on a side away from the second adjusting portion 5133, and the pressing wheel 5131 of the second adjusting portion 5133 is arranged on a side away from the first adjusting portion 5132. The elastic member 5142 may be arranged between the first adjusting portion 5132 and the second adjusting portion 5133, and the elastic force of the elastic member 5142 is used to make the first adjusting portion 5132 and the second adjusting portion 5133 move away from each other. At this time, the pressing wheel 5131 of the first adjusting portion 5132 and the pressing wheel 5131 of the second adjusting portion 5133 simultaneously press the guide wheel 512, so that the two adjusting portions 513 act synchronously on the guide wheel 512.
[0155] See also Fig.14 In one embodiment, the locking assembly 514 further includes a sleeve 5143 and an abutment block 5144. The sleeve 5143 is sleeved on the second end of the locking rod 5141. On the one hand, the sleeve 5143 can be used as a handle of the locking rod 5141. On the other hand, the elastic member 5142 can be arranged inside the sleeve 5143. The sleeve 5143 protects the elastic member 5142 and can also prevent the elastic member 5142 from scratching the operator. It can be understood that the elastic member 5142 partially extends out of the sleeve 5143, which is convenient for the elastic member 5142 to It acts on the second adjusting part 5133; one end of the elastic member 5142 away from the sleeve 5143 is connected to the abutment block 5144, and the abutment block 5144 is located between the second adjusting part 5133 and the sleeve 5143. The elastic member 5142 abuts against the second adjusting part 5133 through the abutment block 5144, which can increase the force area of the second adjusting part 5133, and can also compress the elastic member 5142 by pressing the abutment block 5144, which is convenient for operation and avoids the operator directly pressing the elastic member 5142 and being scratched by the elastic member 5142 during operation.
[0156] See also Figure 14 to Figure 15 In one embodiment, the adjusting portion 513 is provided with a fixing portion 5136 on a side away from the locking rod 5141 , one end of the fixing portion 5136 is hinged to the base 511 , and the other end is rotatably connected to the pressing wheel 5131 .
[0157] It can be understood that one end of the fixing portion 5136 is hinged to the base 511 to achieve relative rotation between the adjusting portion 513 and the base 511, and the other end of the fixing portion 5136 is rotatably connected to the pressure wheel 5131, which can drive the pressure wheel 5131 away from or close to the guide wheel 512; since the pressure wheel 5131 is arranged at the end of the fixing portion 5136, the small-range angular rotation of the fixing portion 5136 can realize a large displacement of the pressure wheel 5131, which is beneficial to the installation of the tin wire.
[0158] See also Fig.14 and Fig.16In one embodiment, the tin adding device 5 includes a coil shaft 5182 and a counting component 517 . The coil shaft 5182 is suitable for placing the tin wire; the counting component 517 is suitable for counting the number of rotations of the guide wheel 512 or the coil shaft 5182 .
[0159] The rotation of the guide wheel 512 drives the transmission of the tin wire, and the coil shaft 5182 rolls to realize the transmission of the tin wire; the counting component 517 calculates the number of rotations of the guide wheel 512 or the coil shaft 5182, and then calculates the used length of the tin wire.
[0160] It can be understood that the guide wheel 512 is used to drive the tin wire to be wound on the coil shaft 5182. When the tin wire is transmitted, the coil shaft 5182 rotates, and the number of turns of the tin wire on the coil shaft 5182 decreases. The length of the tin wire used can be calculated according to the formula through the number of turns of the coil shaft 5182 and the diameter of the coil shaft 5182.
[0161] Alternatively, the length of the used tin wire can be calculated according to the formula by the number of rotations of the guide wheel 512 and the diameter of the guide wheel 512. The tin wire is wound on the coil shaft 5182 to form multiple layers of tin coils from the inside to the outside. The diameter of the tin coil in the outer layer is larger than the diameter of the tin coil in the inner layer. In comparison, the diameter of the guide wheel 512 is more stable, and the length of the used tin wire is calculated by the number of rotations of the guide wheel 512, and the data obtained is more accurate.
[0162] See also Fig.14 In one embodiment, the counting component 517 includes a trigger member 5171 and a first sensor 5172, the trigger member 5171 is fixedly connected to the guide wheel 512; the trigger member 5171 includes a trigger part 5170, and the trigger part 5170 is located on the peripheral side of the guide wheel 512; the first sensor 5172 is arranged on one side of the guide wheel 512; the first sensor 5172 is suitable for detecting the position state of the trigger part 5170.
[0163] It can be understood that the trigger member 5171 rotates synchronously with the guide wheel 512, the trigger portion 5170 is located on the peripheral side of the guide wheel 512, and the first sensor 5172 detects the position state of the trigger portion 5170, calculates the number of rotations of the trigger member 5171, and then obtains the number of rotations of the guide wheel 512. The length of the tin wire passing through the guide wheel 512 is calculated by the diameter and number of rotations of the guide wheel 512.
[0164] Generally, the first sensor 5172 is a photoelectric sensor, which has the characteristics of high detection accuracy and fast response speed, which is conducive to improving the accuracy of counting and reducing measurement errors. During the detection process, the photoelectric sensor does not need to be in direct contact with the trigger member 5171, avoiding physical contact to cause wear or damage to the trigger member 5171, and reducing the impact on the tin wire transmission work; the first sensor 5172 is set on the base 511, and when the trigger member 5171 rotates, the trigger part 5170 passes through the probe of the third sensor 5154, and the third sensor 5154 detects the trigger part 5170, thereby calculating the number of rotations of the guide wheel 512.
[0165] It is understandable that the trigger member 5171 can be a cylinder coaxially arranged with the guide wheel 512, or it can be ring-shaped; the embodiment of the utility model can include a fixing screw, through which the trigger member 5171 and the guide wheel 512 are connected; the trigger member 5171 and the guide wheel 512 can be integrally formed to facilitate processing and installation.
[0166] In one embodiment, the trigger member 5171 is provided with at least two trigger parts 5170, and a detection gap is provided between two adjacent trigger parts 5170. The detection gap is suitable for separating two adjacent trigger parts 5170, so that different trigger parts 5170 can trigger the third sensor respectively.
[0167] See also Fig.14 In one embodiment, the trigger parts 5170 are evenly distributed around the trigger member 5171, which can improve the detection accuracy; for example, two trigger parts 5170 are symmetrically arranged on opposite sides of the trigger member 5171. If the third sensing member detects two trigger parts 5170, the guide wheel 512 rotates one circle, and if the third sensing member detects three trigger parts 5170, the guide wheel 512 rotates one and a half circles, and so on. Similarly, three, four or five trigger parts 5170 can be evenly arranged around the trigger member 5171 to improve the detection accuracy.
[0168] In one embodiment, the trigger member 5171 is a gear, the trigger portion 5170 is the teeth of the gear, and the trigger member 5171 and the guide wheel 512 are coaxially arranged.
[0169] It is understandable that when the gear rotates, the third sensor 5154 detects the teeth of the gear passing by to calculate the number of rotations of the guide wheel 512. The gear is directly used as the trigger member 5171, the procurement cost is low, and there is no need to design and process the trigger member 5171 separately, which is convenient for later maintenance and replacement. The output shaft of the driving member 5153 connects the guide wheel 512 and the trigger member 5171. The output shaft of the driving member 5153 directly drives the guide wheel 512 and the trigger member 5171 to rotate synchronously. At the same time, the output shaft of the driving member 5153 can be used as a connecting member between the guide wheel 512 and the trigger member 5171, so that the guide wheel 512 and the trigger member 5171 are relatively fixed.
[0170] See also Fig.14 In one embodiment, the trigger member 5171 is in the form of a sheet. The sheet-like structure can minimize the space occupied by the trigger member 5171, making the overall structure of the tinning device 5 more compact. Secondly, the sheet-like design can greatly reduce the material used for the trigger member 5171 and reduce the production cost. Since the trigger member 5171 is light and thin in shape, it is easy for the trigger member 5171 to fit the guide wheel 512, thereby reducing the relative movement between the guide wheel 512 and the trigger member 5171 and improving the accuracy of detection. The trigger member 5171 can be a metal sheet. While meeting the requirements of lightweight design, the metal sheet has a certain rigidity to prevent the trigger member 5171 from being deformed due to force during rotation.
[0171] See also Fig.14 In one embodiment, the trigger portion 5170 is rod-shaped; compared with other shapes, the width of the rod-shaped trigger portion 5170 is narrower, which is conducive to forming a detection gap between two adjacent trigger portions 5170 to improve accuracy, and the rod-shaped trigger portion 5170 is relatively slender, and the free end of the trigger portion 5170 extends outward and corresponds to the probe of the third sensor 5154, thereby avoiding other parts such as the guide wheel 512 from affecting the detection work of the third sensor 5154.
[0172] See also Fig.16 In one embodiment, the counting component 517 includes an encoder 5173 and a second sensor 5174. The encoder 5173 is set on the guide wheel 512 or the coil shaft 5182. The second sensor 5174 is suitable for detecting the rotation state of the encoder 5173, and then obtaining the number of rotations of the guide wheel 512 or the coil shaft 5182, so as to facilitate the calculation of the use length of the tin wire.
[0173] Generally, the tin adding device 5 also includes a base 5151, a coil shaft 5182 is rotatably connected to the base 5151, an encoder 5173 is arranged at the end of the coil shaft 5182, and a second sensor 5174 is arranged on the inner wall of the base 5151 and corresponds to the encoder 5173, so as to facilitate the detection of the number of rotations of the coil shaft 5182.
[0174] The encoder 5173 may also be disposed on the guide wheel 512 , and the second sensor 5174 is disposed on the base 511 to calculate the use length of the solder wire by detecting the number of rotations of the guide wheel 512 .
[0175] The encoder 5173 is a magnetic disk or a magnetic steel. Compared with the gear encoder 5173, the magnetic encoder 5173 can provide higher resolution and more accurately detect the rotation position and speed. It is a contactless sensor that can detect the rotation position and speed through the magnetic field without directly contacting the rotating parts. It can better adapt to high-speed rotation and has stronger anti-interference ability against external vibration and temperature changes. The second sensor 5174 can detect the magnetic field change of the encoder 5173, thereby determining the rotation speed and position of the encoder 5173, and then calculating the number of rotations of the guide wheel 512 or the coil shaft 5182. Generally, the second sensor 5174 is a Hall element.
[0176] See also Fig.17 In one embodiment, the tin adding device 5 includes a turntable 5181 and a fourth sensor 5183 . The turntable 5181 is disposed on the base 5151 , and the turntable 5181 rotates relative to the base 5151 . The fourth sensor 5183 is disposed on the base 5151 , and the fourth sensor 5183 is suitable for detecting the weight of the turntable 5181 .
[0177] The tin wire can be placed directly on the turntable 5181. As the tin wire is used, the weight of the turntable 5181 changes accordingly. The usage of the tin wire is judged based on the weight data of the turntable 5181 detected by the fourth sensor 5183 to detect the remaining tin wire. The tin wire is generally rolled tin wire, and the turntable 5181 can rotate flexibly as the tin wire is used to avoid twisting of the tin wire during use, which affects the transmission of the tin wire.
[0178] It can be understood that the turntable 5181 is disposed on the base 5151, and the fourth sensor 5183 is disposed on the base 5151, so that the fourth sensor 5183 can obtain the weight of the turntable 5181; the fourth sensor 5183 is generally a weighing sensor, which is a device that converts a mass signal into a measurable electrical signal output. In other embodiments, the fourth sensor 5183 can also be a pressure sensor.
[0179] See also Fig.18In one embodiment, a movable groove 5152 is provided in the base 5151; the tin adding device 5 also includes a storage member 5191, an elastic member 5193 and a trigger sensor 5192, the storage member 5191 is provided with a material groove 5190 for the tin wire, and the storage member 5191 is movably arranged in the movable groove 5152; the elastic member 5193 connects the bottom of the storage member 5191 and the bottom of the movable groove 5152; the trigger sensor 5192 is arranged on the side wall of the movable groove 5152.
[0180] It is understandable that when the remaining amount of tin wire is sufficient, the elastic member 5193 is compressed. During the use of the tin wire, as the tin wire decreases, the storage member 5191 moves upward under the elastic force of the elastic member 5193. When the tin wire in the trough 5190 is lower than the preset amount, the elastic force of the elastic member 5193 drives the storage member 5191 to move to the set position, triggering the trigger sensor 5192. Through the elastic member 5193 and the trigger sensor 5192, the remaining amount of tin wire can be detected in real time, so as to increase the tin wire in time. The trigger sensor 5192 can be a photoelectric switch.
[0181] According to an embodiment of the present invention, the tin slag outlet 612 is connected to the tin slag collecting box 64, and at least one of the material box 51 and the tin slag collecting box 64 is provided with a weight sensor for detecting the weight of the tin wire and the tin slag.
[0182] In an optional embodiment, the material box 51 is provided with a weight sensor, which can detect the remaining weight of the tin wire in the material box 51. By monitoring the weight, the operator can promptly learn about the destruction of the tin wire without having to wait until the tin wire in the material box 51 is completely used up. This helps to avoid production interruptions or pauses caused by lack of tin wire, and can promptly discover whether the tin wire needs to be replenished to maintain the continuity and stability of the production process.
[0183] In another optional embodiment, the tin slag outlet 612 is connected to the tin slag collection box 64, and the tin slag separated by the tin slag separation device 6 is stored in the tin slag collection box 64 through the tin slag outlet 612. The tin slag collection box 64 can be provided with a weight sensor, and the weight sensor can monitor the weight change of the tin slag in the tin slag collection box 64 in real time, and provide data support for the improvement and optimization of the production process. These data can help production managers better understand the generation rate and accumulation law of tin slag, and then formulate more reasonable production and management strategies. In some embodiments, when the weight of the tin slag in the tin slag collection box 64 reaches a set threshold, the weight sensor can sound an alarm to remind the operator that the tin slag collection box 64 needs to be cleaned or replaced in time.
[0184] In another optional embodiment, the material box 51 and the tin slag collection box 64 are both provided with weight sensors, which can fully understand the consumption of raw materials and the generation of waste materials during the welding process, and help to achieve comprehensive management and control of the production process. Comprehensive analysis of the weight data of the material box 51 and the tin slag collection box 64 can provide a deeper understanding of the material flow and resource utilization in the production process. This helps production managers to formulate more accurate production plans and resource allocation strategies, improve production efficiency and resource utilization, and establish a more comprehensive early warning mechanism to ensure the continuity and stability of the production process.
[0185] According to one embodiment of the present invention, referring to Fig.11 As shown, the wave soldering device 4 further includes a lifting assembly 900 , which is connected to the tin furnace 600 and is used to adjust the height of the tin furnace 600 .
[0186] It is understandable that a lifting assembly 900 is also provided in the present embodiment, and the lifting assembly 900 can adjust the height of the tin furnace 600. Through the lifting assembly 900, the operator can flexibly adjust the height of the tin furnace 600 according to the actual welding needs to ensure that the solder can effectively wet the surface of the welded parts during the welding process, thereby obtaining a high-quality welded joint. Wave soldering usually involves workpieces of different types and sizes, and these workpieces may require welding conditions of different heights. By adjusting the height of the tin furnace 600 through the lifting assembly 900, the requirements of different workpieces can be met to ensure welding quality and consistency. Through the lifting assembly 900, the operator can adjust the height of the tin furnace 600 at any time during the welding process, which improves the convenience and efficiency of operation and reduces production downtime.
[0187] In some embodiments, the lifting assembly 900 may also be provided with a safety protection structure, such as a limit switch or a safety sensor, to ensure that the tin furnace 600 is stable and reliable during the lifting process to avoid accidents or damage to the equipment.
[0188] According to one embodiment of the present invention, referring to Fig.11 As shown, the lifting assembly 900 includes a support frame 910 and a lifting screw rod 920. A guide wheel 911 is installed at the bottom of the support frame 910. One end of the lifting screw rod 920 can be lifted and installed on the support frame 910, and the other end is connected to the tin furnace 600.
[0189] It is understandable that in this embodiment, a guide wheel 911 is installed at the bottom of the support frame 910, and the guide wheel 911 can make the support frame 910 more convenient to move, thereby driving the position adjustment of the tin furnace 600, facilitating the installation and commissioning of the tin furnace 600, and can adapt to circuit boards of different sizes and shapes. Exemplarily, the guide wheel 911 can be a universal wheel that can be freely selected in all directions, so that the support frame 910 and the tin furnace 600 are easier to move and adjust the position.
[0190] One end of the lifting screw 920 is fixed on the support frame 910, and the other end is connected to the tin furnace 600. The lifting screw 920 can realize the up and down movement of the tin furnace 600. The lifting screw 920 usually has a threaded structure, and its thread cooperates with the nut or the guide rod, so that the tin furnace 600 can move up and down smoothly when the screw is rotated. By controlling the rotation direction and rotation amount of the lifting screw 920, the height of the tin furnace 600 can be accurately adjusted to meet the requirements of different workpieces and the needs of the welding process.
[0191] According to one embodiment of the present invention, referring to Fig.11 As shown, the wave soldering machine includes a conveying device 3 for conveying circuit boards, and a tinning device 5 and a wave soldering device 4 are arranged side by side below the conveying device 3 along the conveying direction of the conveying device 3 .
[0192] It can be understood that, in this embodiment, the conveying device 3 is used to convey the circuit board, which can be a conveyor belt or a conveyor chain, and is used to convey the circuit board to be soldered to the top of the tin furnace 600 for soldering. The tinning device 5 and the wave soldering device 4 are arranged side by side below the conveying device 3 along the conveying direction of the conveying device 3. This arrangement makes the structure of the wave soldering machine compact, which can minimize the occupied space, reduce the volume of the wave soldering machine, and improve production efficiency and work flexibility.
[0193] According to one embodiment of the utility model, the wave soldering machine also includes a tin slag salvaging device (not shown in the figure), which is connected to the tin cavity and the tin slag separation device 6, and is used to salvage the tin slag in the tin cavity and transport it to the tin slag separation device 6 for separation.
[0194] It can be understood that the present embodiment is also provided with a tin slag salvaging device for salvaging the tin slag in the tin furnace 600, and the salvaged tin slag is transported to the tin slag separation device 6 for tin slag separation, without the need for manual salvaging, thereby greatly reducing labor costs and improving production efficiency.
[0195] It is understandable that the tin slag salvaging device will inevitably be mixed with tin liquid when salvaging the tin slag in the tin furnace 600, and the mixture of tin slag and tin liquid can be transported to the tin slag separation device 6 for separation. In an optional embodiment, the tin slag salvaging device and the tin slag separation device 6 can share a driving motor, which saves energy, reduces costs and facilitates maintenance, and can also realize the simultaneous performance of tin slag salvaging and tin slag separation.
[0196] According to one embodiment of the present invention, referring to Fig.10 As shown, the wave soldering device 4 also includes a base 100, a spoiler wave generating component 200, a flat wave generating component 300 and a driving component 700. The base 100 is formed with a guide cavity, a wave crest generating mechanism is connected to the base 100, the wave crest generating mechanism is formed with a wave crest nozzle, the wave crest nozzle is connected to the guide cavity, and the wave crest nozzle is formed with a spoiler wave area and a flat wave area, the spoiler wave area is provided with a spoiler wave generating component 200, and the flat wave area is provided with a flat wave generating component 300; the driving component 700 is connected with the guide cavity and the tin cavity, and is used for conveying tin liquid from the tin cavity to the spoiler wave generating component 200 and the flat wave generating component 300 to generate spoiler waves and flat waves.
[0197] The spoiler wave generating assembly 200 and the peaceful wave generating assembly 300 share a wave crest nozzle, and both the spoiler wave generating assembly 200 and the peaceful wave generating assembly 300 are connected to the guide cavity. Only one driving motor is required to convey the solder into the guide cavity, so that the spoiler wave generating assembly 200 and the peaceful wave generating assembly 300 can be welded, thereby realizing the integration of the spoiler wave and the peaceful wave, that is, the spoiler wave assembly and the peaceful wave assembly can work at the same time, 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 required to convey the solder, which reduces the energy consumption and the production cost compared with the traditional two motors driving the spoiler wave generating assembly 200 and the peaceful wave generating assembly 300 to work separately.
[0198] 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.
[0199] Since the operation of the spoiler wave generating component 200 and the horizontal wave generating component 300 can be realized by a driving component 700, compared with the previous design in which the spoiler wave generating component 200 and the horizontal wave generating component 300 are independently driven by a driving motor 633, one driving motor 633, an impeller, a frequency converter, a guide structure and a base 100 can be reduced, thereby greatly saving the manufacturing cost and maintenance cost of the wave soldering device 4.
[0200] According to one embodiment of the present invention, referring to Figure 3 and Fig.10 As shown, the wave soldering device 4 is provided with a guide component 800, one end of the guide component 800 is connected to at least one of the turbulent wave generating component 200 and the peaceful wave generating component 300, and the other end is connected to the tin furnace 600 to reflux the sprayed tin liquid. The tin liquid sprayed from at least one of the turbulent wave generating component 200 and the peaceful wave generating component 300 is suitable for flowing back to the tin furnace 600 after being guided by the guide component 800.
[0201] Exemplarily, the flow guide component 800 can be arranged at the lower side of the disturbance wave generating component 200 or the flat wave generating component 300 to effectively guide the ejected tin liquid back to the tin furnace 600 to achieve buffering. In some embodiments, the height of the flow guide component 800 is between the height of the disturbance wave generating component 200 and the liquid level height of the tin furnace 600, so as to achieve buffering for the tin liquid ejected from the disturbance wave generating component and prevent the tin liquid from falling directly into the tin furnace 600. By setting the flow guide component 800 to guide the tin liquid back to the tin furnace 600, the problem of large impact force generated by the direct drop of the tin liquid can be effectively solved, thereby improving the stability during the welding process, making the welding process more stable and reliable, and reducing the adverse effects on the welding quality.
[0202] According to one embodiment of the present invention, referring to Figure 1 As shown, the wave soldering device 4 includes at least one of a first adjusting member 410 and a second adjusting member 420, wherein the first adjusting member 410 is connected to the spoiler wave generating assembly 200 for adjusting the parameters of the spoiler wave; the second adjusting member 420 is connected to the flat wave generating assembly 300 for adjusting the parameters of the flat wave.
[0203] In an optional embodiment, the first adjusting member 410 includes a first operating part 411 and a first transmission part 412, the first operating part 411 is connected to the spoiler wave generating assembly 200 through the first transmission part 412, and the first operating part 411 is at least partially arranged outside the tin furnace 600; and / or, the second adjusting member 420 includes a second operating part 421 and a second transmission part 422, the second operating part 421 is connected to the smooth wave generating assembly 300 through the second transmission part 422, and the second operating part 421 is at least partially arranged outside the tin furnace 600, and the parameters of the spoiler wave generating assembly 200 or the smooth wave generating assembly 300 can be adjusted outside the tin furnace 600, thereby improving the safety performance of the operation.
[0204] According to one embodiment of the present invention, referring to Figures 19 to 22 As shown, the wave soldering device 4 is provided with an anti-oxidation device, which includes: an anti-oxidation cover 8; a fixing member 81, the anti-oxidation cover 8 is connected to the fixing member 81, and an anti-oxidation cavity is formed so that the transmission bearing 710 of the driving component 700 is located in the anti-oxidation cavity; an air inlet 82, the air inlet 82 is connected to the anti-oxidation cavity, and the air inlet 82 is suitable for introducing anti-oxidation gas into the anti-oxidation cavity.
[0205] In the existing tin furnace 600, liquid tin is easily oxidized when in contact with air and produces tin slag. The tin slag produced by oxidation is adsorbed on the transmission shaft of the wave soldering device 4, and moves upward with the help of the rotational power of the transmission shaft to reach the transmission bearing 710, causing the transmission bearing 710 to get stuck.
[0206] The anti-oxidation cover 8 is provided with a fixing part 81 and an air inlet part 82. The anti-oxidation cover 8 is connected to the fixing part 81, and an anti-oxidation cavity is formed, so that the transmission bearing 710 of the wave soldering device 4 is located in the anti-oxidation cavity; the air inlet part 82 is connected to the anti-oxidation cavity, and the air inlet part 82 is suitable for introducing anti-oxidation gas into the anti-oxidation cavity.
[0207] The anti-oxidation cover 8 and the fixing part 81 are connected to each other to form an anti-oxidation cavity, and the anti-oxidation gas is introduced into the cavity through the air inlet part 82, so that the liquid tin can be always in contact with the anti-oxidation gas, preventing the liquid tin from contacting with the air to produce tin slag and further damaging the bearing.
[0208] In specific implementation, the transmission bearing 710 located therein can be protected by introducing an anti-oxidation gas into the anti-oxidation cavity, wherein the anti-oxidation gas can be nitrogen, carbon dioxide, and an inert gas (such as helium), etc., and nitrogen is used as an example in this embodiment. The introduction of the anti-oxidation gas into the anti-oxidation cavity can isolate the contact between the liquid tin and the air, reduce the amount of tin slag generated inside the anti-oxidation cover 8, thereby reducing the tin slag adsorbed on the transmission bearing 710 and preventing the transmission bearing 710 from being damaged.
[0209] According to some embodiments of the utility model, only a cavity can be set in the anti-oxidation cover 8 to form the above-mentioned anti-oxidation cavity, and the transmission bearing 710 can be set in the anti-oxidation cover 8 to protect it. On this basis, in other embodiments, a cavity can also be set in the fixing member 81, and the cavity is connected with the cavity in the anti-oxidation cover 8. The cavity formed in the fixing member 81 is connected with the cavity formed in the anti-oxidation cover 8 to form an anti-oxidation cavity, which can increase the volume of the anti-oxidation cavity and improve the protection effect. In addition, the anti-oxidation gas can be introduced into the anti-oxidation cavity through the cavity formed in the fixing member 81 to improve the flexibility of the pipeline connection. The fixing member 81 plays a fixing role and is used to connect with the wave soldering device 4, so as to fix the anti-oxidation cover 8. When in use, since the fixing member 81 is located above the anti-oxidation cover 8, the cavity inside it is far away from the liquid surface of the liquid tin. Therefore, under the premise of satisfying the spatial layout, the transmission bearing 710 is usually set in the cavity formed in the fixing member 81.
[0210] According to some embodiments of the present invention, reference Fig.19 , Fig. 20 and Fig.21As shown, the fixing member 81 is threadedly connected to the anti-oxidation cover 8 to adjust the height of the lower end of the anti-oxidation cover 8 when the anti-oxidation cover 8 is rotated. By configuring the fixing member 81 and the anti-oxidation cover 8 to be threadedly connected, the height of the anti-oxidation cover 8 can be adjusted by rotating the anti-oxidation cover 8, and then the position of the lower end of the anti-oxidation cover 8 relative to the liquid tin liquid surface can be adjusted so that the lower end of the anti-oxidation cover 8 is always below the liquid tin liquid surface, thereby preventing air from entering the anti-oxidation cavity. It is convenient to adjust the height of the anti-oxidation cover 8 by manually rotating the anti-oxidation cover 8, and it is also convenient to rotate the anti-oxidation cover 8 with the help of an external drive structure to achieve automatic adjustment. It is convenient to install and disassemble the fixing member 81 and the anti-oxidation cover 8, and clean the tin slag inside the anti-oxidation cover 8 and the fixing member 81. In the case of protecting the transmission bearing 71050 by introducing anti-oxidation gas into the anti-oxidation cavity, the threaded connection between the fixing member 81 and the anti-oxidation cover 8 can also ensure the airtightness of the anti-oxidation cavity and prevent the anti-oxidation gas from overflowing through the connection position between the fixing member 81 and the anti-oxidation cover 8. In addition, by configuring the fixing member 81 and the anti-oxidation cover 8 to be threadedly connected, after the anti-oxidation cover 8 is adjusted, the threaded self-locking can be used to keep the anti-oxidation cover 8 at the current height without any other constraints, and there is no need to set an additional limiting mechanism to limit the anti-oxidation cover 8.
[0211] According to an embodiment of the present invention, the fixing member 81 is detachably connected to the anti-oxidation cover 8 and forms an anti-oxidation cavity so that the transmission bearing 710 of the wave soldering device 4 is located in the anti-oxidation cavity.
[0212] In this embodiment, the anti-oxidation cover 8 and the fixing member 81 are configured to be detachably connected. When tin slag is generated inside the anti-oxidation cover 8, the interconnected anti-oxidation cover 8 and the fixing member 81 can be detached, thereby facilitating cleaning of the inside of the anti-oxidation cover 8.
[0213] According to one embodiment of the present invention, referring to Fig.11 and Fig.23 As shown, the wave soldering machine also includes a wave soldering spraying device 2, which includes: a base 511; a nozzle assembly 25, which is arranged on the base 511 and is used to spray flux; a longitudinal moving assembly 26, which is arranged on the nozzle assembly 25 and is used to drive the nozzle assembly 25 to move longitudinally; and a transverse moving assembly 27, which is arranged on the longitudinal moving assembly 26 to drive the nozzle assembly 25 to move transversely.
[0214] In the related art, when the wave soldering equipment performs wave soldering on electronic components on the circuit board, a layer of flux needs to be sprayed on the circuit board in advance according to the process requirements to achieve better welding quality. However, in the process of spraying this layer of flux, the entire circuit board is often sprayed with a layer of flux, but in fact, it is only necessary to selectively spray the flux on the local area where the electronic components are to be soldered to meet the product's welding requirements; therefore, the existing flux spraying process will cause a waste of flux due to the large spraying area, increase production costs, and also affect welding efficiency.
[0215] In this embodiment, the bracket 21 is the support platform of the entire wave soldering spraying device 2, and a mounting cavity is formed to provide a foundation and stability for the installation of other components. The nozzle assembly 25, the longitudinal moving assembly 26 and the lateral moving assembly 27 can all be installed in the mounting cavity, so that the various components can cooperate closely and work together to achieve precise spraying operations on the circuit board. Through this design, the bracket 21 not only supports and fixes other components, but also provides a unified mounting platform for the entire wave soldering spraying device 2, which is convenient for maintenance and operation. The positions of the nozzle assembly 25, the longitudinal moving assembly 26 and the lateral moving assembly 27 in the mounting cavity can cooperate with each other to achieve the movement and adjustment required for the spraying operation, thereby ensuring the accuracy and efficiency of the spraying.
[0216] In an alternative embodiment, reference Fig.23 As shown, the bracket 21 can adopt a frame structure, and the four sides of the bracket 21 can be closed by panels. This design can effectively provide a stable support platform, and the closed panels can protect the internal components and prevent the entry of dust or other impurities, thereby keeping the equipment clean and safe. The bracket 21 of the frame structure is usually made of a solid metal material, such as steel or aluminum alloy, to ensure sufficient load-bearing capacity and stability. At the same time, the closed design of the panel helps to reduce noise in the working environment and prevent accidental contact with internal moving parts, thereby improving the overall safety of the equipment.
[0217] Furthermore, an adjustment button can be set on the panel of the bracket 21. By setting the adjustment button on the panel, the operator can easily adjust the spraying parameters, such as spraying speed, spraying pressure, nozzle 202 angle, etc., so as to achieve precise control and adjustment of the spraying process. Through this design, the operator can adjust the spraying parameters at any time according to actual needs to ensure the stability and accuracy of the spraying process.
[0218] The nozzle assembly 25 is located in the installation cavity, and its main function is to spray the solder flux. By controlling the position of the nozzle assembly 25, spraying of a specific area of the circuit board can be achieved. The longitudinal movement assembly 26 and the lateral movement assembly 27 work together to control the longitudinal movement and lateral movement of the spray assembly to achieve position adjustment of the nozzle assembly 25.
[0219] Flux is an auxiliary material used in the welding process, and its main function is to help improve welding quality and efficiency. Flux is usually coated on the welding surface, and plays a role in cleaning, anti-oxidation, and promoting wetting during the welding process, which helps the contact and diffusion of solder with the workpiece surface, thereby improving welding quality and reliability.
[0220] It can be understood that in this embodiment, reference Fig.23 and Fig.24 As shown, the wave soldering spraying device 2 includes a bracket 21 and a nozzle assembly 25, forming an installation cavity; the nozzle assembly 25 is arranged in the installation cavity for spraying solder flux; the longitudinal moving assembly 26 is arranged in the nozzle assembly 25 for driving the nozzle assembly 25 to move longitudinally; the transverse moving assembly 27 is arranged in the longitudinal moving assembly 26 to drive the nozzle assembly 25 to move transversely. By arranging the longitudinal moving assembly 26 and the transverse moving assembly 27 to drive the spraying assembly to move, selective area spraying of solder flux on the circuit board to be soldered is achieved, avoiding the problem of flux waste caused by spraying the entire circuit board, which is conducive to saving costs and improving soldering quality and efficiency.
[0221] According to one embodiment of the present invention, referring to Fig.23 As shown, the nozzle assembly 25 includes: a guide rod 251, which is arranged along the height direction of the wave soldering spraying device 2; a sliding block 252, which is slidably arranged on the guide rod 251 and slides along the guide rod 251; and a nozzle 253, which is installed on the sliding block 252.
[0222] It can be understood that in this embodiment, the guide rod 251 is arranged along the height direction of the wave soldering spray device 2, and the slider is installed on the guide rod 251 and can be slid thereon, and the nozzle 253 is installed on the sliding block 252, so that the operator can easily adjust the height of the nozzle 253. The operator can adjust the height of the nozzle 253 as needed to ensure the accuracy and adaptability of the spraying process, which is suitable for circuit boards of different types and sizes, helps to improve production efficiency and ensure the quality of spraying.
[0223] In some embodiments, a threaded structure can be provided between the sliding block 252 and the guide rod 251, and the position of the sliding block 252 can be adjusted by rotating a nut or a bolt, thereby changing the height of the nozzle 253. This adjustment method is simple and effective, has high adjustment accuracy and good stability, and can maintain the adjusted position for a long time. It can also achieve slight height adjustments, thereby meeting process requirements for higher position accuracy of the nozzle 253.
[0224] According to an embodiment of the present invention, the spray head 253 is provided with a solenoid valve to adjust the flow rate of the spray head 253 .
[0225] It can be understood that in this embodiment, the flow rate of the flux sprayed from the nozzle 253 can be adjusted by controlling the opening of the solenoid valve. The solenoid valve, as a control element, can be controlled to open or close according to an external signal or instruction, thereby adjusting the flow of the flux in the pipeline.
[0226] In the wave soldering spraying device 2, the flow control of the nozzle 253 is crucial to ensure coating uniformity and spraying quality. By setting a solenoid valve, the flow of the nozzle 253 can be accurately adjusted to meet the spraying requirements of different process requirements and workpiece characteristics. The operator can adjust the flow size of the nozzle 253 by controlling parameters such as the opening time, frequency or opening of the solenoid valve, thereby controlling the spraying amount of the coating or liquid. This flow regulation method can achieve rapid response and precise control, and improve the stability and reliability of the spraying process.
[0227] It can be understood that in this embodiment, the types of solenoid valves include but are not limited to direct-acting solenoid valves, indirect solenoid valves, diaphragm solenoid valves, sleeve solenoid valves, plug-in solenoid valves, etc., which can be selected according to different flux, pressure, temperature requirements and control methods to ensure the normal and stable operation of the nozzle assembly 25. This embodiment does not make specific limitations on this.
[0228] According to one embodiment of the present invention, referring to Fig.24 and Fig.25 As shown, the wave soldering spray device 2 also includes a position sensor 22 and a controller. The position sensor 22 is used to detect the position information of the circuit board to be soldered; the controller connects the position sensor 22, the longitudinal moving component 26 and the lateral moving component 27 to control the operation of the longitudinal moving component 26 and the lateral moving component 27 based on the position information of the circuit board to be soldered.
[0229] It is understandable that in this embodiment, by detecting the position of the circuit board, the spraying position and direction can be determined, thereby accurately controlling the flux spraying process. Once the position sensor 22 detects the position of the circuit board, the controller can adjust the position and movement trajectory of the spray head according to this information. In this way, it can be ensured that the flux is accurately sprayed in the area where welding is required, thereby improving welding quality and efficiency. By automating the spraying process, the possibility of human error can also be reduced and production consistency can be improved.
[0230] According to one embodiment of the present invention, referring to Fig.23 and Fig.24 As shown, at least one of the longitudinal moving assembly 26 and the lateral moving assembly 27 is installed with a shock absorbing pad 23 .
[0231] It can be understood that in this embodiment, by installing the shock-absorbing pad 23 in at least one of the longitudinal moving assembly 26 and the transverse moving assembly 27, the vibration and impact generated by the equipment during movement can be effectively absorbed and reduced, preventing these vibrations from damaging the equipment structure and key components or affecting the normal operation of the equipment, effectively extending the service life of the equipment, and improving the stability and safety of the equipment. Reducing vibration and impact also helps to reduce the noise level when the equipment is running and improve the working environment.
[0232] In addition, reducing vibration and shock during the movement of the equipment can also help reduce errors. Vibration and shock will have a negative impact on the operating stability and accuracy of the equipment, which may cause errors and instability in the production process. By installing the shock-absorbing pad 23, the stability and accuracy of the equipment can be improved, the possibility of errors can be reduced, and thus production efficiency and product quality can be improved.
[0233] In an optional embodiment, both the longitudinal moving assembly 26 and the lateral moving assembly 27 are provided with a shock absorbing pad 23, which can effectively absorb and reduce the vibration and impact generated by the device in different directions. This design can enable the device to obtain a good shock absorbing effect in various mobile operations, reduce the possibility of vibration transmission to other parts of the device, and thus extend the service life of the device.
[0234] It should be noted that the types of the shock absorbing pad 23 include but are not limited to spring shock absorbing pad 23, shock absorber shock absorbing pad 23, liquid shock absorbing pad 23 and gas shock absorbing pad 23, etc., which can be selected according to specific application requirements, and this embodiment does not make specific limitations on this.
[0235] According to one embodiment of the present invention, referring to Fig.25As shown, the wave soldering spraying device 2 is also provided with a cable guide chain 24, which is used to guide the cable. It can be understood that in this embodiment, the cable guide chain 24 is a device for guiding the cable. The cable guide chain 24 is usually composed of a plurality of rollers or guide wheels 512, and its function is to ensure that the cable can maintain stable guidance during movement and prevent the cable from being entangled, crossed or messy during movement.
[0236] The cable guide chain 24 is provided in the wave soldering spraying device 2 to help maintain the cable position required during the soldering / spraying process stable and accurate. By properly setting the cable guide chain 24, it can be ensured that the cable can be guided according to the design requirements during the operation of the equipment, avoiding accidental pulling or crossing, thereby improving the stability and safety of the equipment operation.
[0237] In an optional embodiment, the cable guide chain 24 may be formed with a guide groove 241, and the cable is arranged in the guide groove 241, which can effectively limit the movement range of the cable and guide it along a designed path. Such a design can improve the neatness and reliability of cable routing, reduce the risk of cable damage, and also help maintain the safety and stability of the equipment.
[0238] According to an embodiment of the present invention, the nozzle assembly 25 is provided with a flow sensor, and the flow sensor is used to detect the flux flow of the nozzle 253 of the nozzle assembly 25 .
[0239] It is easy to understand that in this embodiment, a flow sensor is installed on the nozzle assembly 25, which can monitor the flow of the flux in real time to ensure that the nozzle 253 provides an accurate spraying amount during operation. This helps to control the material consumption during welding or spraying and improve the stability and controllability of production. The flow sensor can feed back the detected flow signal to the control system so as to adjust the working state of the nozzle 253 in time to maintain the required spraying amount. This real-time feedback and adjustment mechanism can help improve production efficiency and avoid waste and unnecessary costs.
[0240] Furthermore, monitoring the flux flow rate can also help determine whether the nozzle 253 is clogged or leaking. When the nozzle 253 is clogged, the flow sensor will detect a sudden decrease or even interruption in the flow rate, which will trigger an alarm and prompt the operator to check and clean. In addition, if a leak occurs, the flow sensor will also detect abnormal flow conditions, thereby promptly discovering and solving the leakage problem and ensuring the stability and safety of the production process.
[0241] In this embodiment, the types of flow sensors include but are not limited to mechanical flow sensors, electromagnetic flow sensors, ultrasonic flow sensors, thermal flow sensors, eddy current flow sensors and mass flow sensors, etc. As long as they can detect the flow rate of the flux, they can be selected according to the specific application scenario. This embodiment does not make any specific limitations on this.
[0242] According to one embodiment of the utility model, referring to Figure 1-Figure 10 As shown, a wave soldering nozzle structure and a wave soldering device are also provided.
[0243] In the related art, the wave soldering device is provided with a spoiler wave generating component 200 and a calm wave generating component 300, which are used to generate spoiler waves and calm waves respectively. However, the spoiler wave parameters and the calm wave parameters are not convenient to adjust, resulting in a mismatch between the spoiler wave parameters and the calm wave parameters, which may cause the welding speed to be unstable and generate more tin slag. It is also easy to cause unreasonable energy distribution of spoiler waves and calm waves, resulting in obvious differences in temperature in the space of the welding area, which is easy to cause welding deformation, thereby affecting the quality and strength of welding and affecting the welding efficiency.
[0244] According to an embodiment of the present utility model, please refer to Figure 1 As shown, a wave soldering nozzle structure is provided, including a base 100, which is formed with a guide cavity suitable for communicating with a tin furnace 600; a spoiler wave generating component 200 and a smooth wave generating component 300, which are arranged on the base 100, and the spoiler wave generating component 200 and the smooth wave generating component 300 are both connected to the guide cavity to generate spoiler waves and smooth waves respectively; an adjusting component 400, including a first adjusting member 410 and a second adjusting member 420, the first adjusting member 410 is connected to the spoiler wave generating component 200, and is used to adjust the parameters of the spoiler wave; the second adjusting member 420 is connected to the smooth wave generating component 300, and is used to adjust the parameters of the smooth wave.
[0245] It can be understood that in this embodiment, the guide cavity of the base 100 can be connected to the tin furnace 600 of the wave soldering device to supply solder into the guide cavity. The solder in the guide cavity can be sprayed into the welding area through the turbulent wave generating component 200 and the flat wave generating component 300 respectively to form turbulent waves and flat waves to achieve welding of the circuit board.
[0246] The spoiler wave generating assembly 200 is provided with a spoiler wave nozzle 201, through which the tin liquid can be sprayed to the welding area and a spoiler wave is generated, thereby enhancing the mixing degree of the tin liquid and improving the welding quality. The spoiler wave nozzle 201 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 201 can also adjust the angle and effect of the spray by changing the parameters such as the position, size and shape of the hole, thereby meeting the needs in different occasions.
[0247] The advection wave generating assembly 300 is provided with an advection wave nozzle 301, 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 301 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.
[0248] 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 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 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 in 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.
[0249] It should be noted that, in this embodiment, the parameters of the spoiler wave may include at least one of the cross-sectional area and the injection angle of the spoiler wave, and the parameters of the flat wave may include at least one of the cross-sectional area and the height of the flat wave.
[0250] The welding time can be adjusted by adjusting the jet angle of the spoiler wave, 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.
[0251] 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.
[0252] In this embodiment, the spoiler wave parameters and the flat wave parameters are adaptively adjusted by respectively setting the first adjusting member 420, so that the spoiler wave parameters and the flat wave parameters can match each other. For example, the height of the flat wave can be adaptively adjusted while adjusting the spoiler wave angle, which can better control the energy distribution and temperature distribution in the welding process, achieve better welding effect, and help improve welding quality and production efficiency.
[0253] According to an embodiment of the present invention, the first adjusting member 410 and the second adjusting member 420 are coupled to each other for transmission.
[0254] In an optional embodiment, the first adjusting member 410 and the second adjusting member 420 can be designed as a coupling transmission. Through the coupling transmission, when the first adjusting member 410 is adjusted, the second adjusting member 420 will be automatically adjusted accordingly, thereby maintaining the matching between the turbulent wave and the flat wave, and optimizing the stability and quality of the welding process.
[0255] Since coupling transmission is realized between the first adjusting member 410 and the second adjusting member 420, adjusting any one parameter will synchronously adjust the other parameter, thereby improving the convenience of adjustment and making the adjustment process faster and more efficient. The coupling transmission design can ensure that the parameter adjustment between the spoiler wave and the flat wave remains synchronized, thereby achieving precise control of the welding process, better maintaining the stability of the welding process, and improving the welding quality.
[0256] For example, the first adjusting member 410 and the second adjusting key can be connected by mechanical elements such as gears, belts, and chains so that their movements are interrelated; the synchronous adjustment between the first adjusting member 410 and the second adjusting member 420 can also be achieved through electrical components such as motors, sensors, and actuators; or hydraulic components such as hydraulic cylinders, valves, and pipelines can be used to transfer hydraulic energy to various components to achieve synchronous adjustment between the first adjusting member 410 and the second adjusting member 420.
[0257] According to the wave soldering nozzle structure of the utility model embodiment, refer to Figure 1 and Figure 7 As shown, the first adjusting member 410 includes a first operating part 411 and a first transmission part 412, and the first operating part 411 is connected to the spoiler wave generating component 200 through the first transmission part 412; the second adjusting member 420 includes a second operating part 421 and a second transmission part 422, and the second operating part 421 is connected to the flat wave generating component 300 through the second transmission part 422, and the first transmission part 412 and the second transmission part 422 are matched in transmission.
[0258] It is understandable that, in this embodiment, the first adjustment member 410 includes a first operating portion 411 and a first transmission portion 412, the first operating portion 411 may be a handle, a button or other control device, which is convenient for the user to operate, and the first transmission portion 412 is responsible for transmitting the movement of the first operating portion 411 to the spoiler wave generating assembly 200, which may be achieved through mechanical devices such as gears, chains, and transmission belts. The second adjustment member 420 also includes a second operating portion 421 and a second transmission portion 422. The adjustment form of the second operating portion 421 can be similar to that of the first operating portion 411, which is convenient for the user to adjust the parameters of the flat wave, and the second transmission portion 422 transmits the movement of the second operating portion 421 to the flat wave generating assembly 300 to achieve the adjustment of the parameters of the flat wave.
[0259] At the same time, there is a transmission match between the first transmission part 412 and the second transmission part 422, so that the movement or parameter adjustment between the first adjustment member 410 and the second adjustment member 420 is mutually related and synchronous. This match can ensure that the parameter adjustment between the spoiler wave and the flat wave remains synchronous, so as to optimize the stability and quality of the welding process.
[0260] The first transmission part 412 and the second transmission part 422 can adopt structures such as gears or screws to ensure that the first adjustment member 410 and the second adjustment member 420 have high adjustment accuracy, maintain stable transmission performance, and improve the reliability of the adjustment of the parameters of the spoiler wave and the flat wave.
[0261] In an optional embodiment, the first operating part 411 and the second operating part 421 are arranged side by side, which makes it easier for the operator to control the two components for adjustment at the same time, thereby improving the convenience and efficiency of user operation, especially when the two components need to be adjusted or controlled at the same time; in another optional embodiment, the first transmission part 412 and the second transmission part 422 are arranged side by side, which facilitates placing the first transmission part 412 and the second transmission part 422 in the same structure and sharing some outer shells or supporting structures. The side-by-side arrangement is also conducive to simplifying the design and installation of the first adjustment member 410 and the second adjustment member 420 and reducing the occupied space.
[0262] According to one embodiment of the present invention, referring to Figure 1 As shown, the first adjusting member 410 and the second adjusting member 420 are arranged on the same side of the base 100, which saves space and makes the wave soldering nozzle structure more compact. This helps to design and install the first adjusting member 410 and the second adjusting member 420 in a limited space, and at the same time facilitates the operator to make adjustments, thereby improving the convenience and efficiency of user operations.
[0263] According to one embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the wave soldering nozzle structure also includes a guide groove 500, and a first connecting seat 510 is arranged on both sides of the guide groove 500. The second connecting seat 120 is correspondingly arranged on both sides of the base 100. The first connecting seat 510 and the second connecting seat 120 located on the same side are connected by a connecting rod 520, so that the base 100 is connected to the tin furnace 600 through the guide groove 500.
[0264] It can be understood that, in this embodiment, the wave soldering nozzle structure also includes a guide groove 500, and the driving mechanism can connect the guide groove 500 and the tin furnace 600, and the tin liquid in the tin furnace 600 is transported to the spoiler wave generating component 200 and the smooth wave generating component 300 through the guide groove 500 to generate spoiler waves and smooth waves. By connecting the guide groove 500 and the tin furnace 600 through the driving mechanism, the effective transportation of the tin liquid can be achieved, ensuring that the liquid can be accurately and stably transported to the corresponding wave generating component during the welding process. The design of the guide groove 500 can effectively control the flow direction and speed of the tin liquid, thereby ensuring that the flow state of the liquid during the welding process meets the requirements, which is conducive to the precise control and regulation of welding.
[0265] By connecting the first connecting seat 510 and the second connecting seat 120 through the connecting rod 520, it can be ensured that the connection between the base 100 and the tin furnace 600 is firm and reliable, and is not easy to loosen or shift during the welding process. The existence of the connecting rod 520 can enhance the structural stability between the base 100 and the tin furnace 600, prevent tilting or instability during use, and ensure the normal operation of the equipment.
[0266] According to one embodiment of the present invention, referring to Figure 2 As shown, there are multiple connecting rods 520, and the heights of the multiple connecting rods 520 are adjustable.
[0267] In this embodiment, the number of connecting rods 520 can be multiple, and multiple connecting rods 520 can be distributed around the base 100, which can evenly support the base 100 and enhance the stability and bearing capacity of its overall structure. At the same time, the height of the multiple connecting rods 520 can be adjusted, so as to adjust the height of the base 100, adjust the front and back, left and right levels of the base 100, reduce the shaking or instability caused by the uneven height of the base 100, and ensure the safety and stability of welding; adjusting the height of the base 100 can make it stably connected with the tin furnace 600, ensure the stability of the workpiece during welding, and thus improve the welding quality.
[0268] In an optional embodiment, a seal can be provided between the base 100 and the guide groove 500 to prevent leakage of tin liquid and ensure that the molten solder will not leak out from the gap between the base 100 and the guide groove 500 when flowing in the guide groove 500 during welding, thereby maintaining normal welding operation. The seal can be made of high temperature resistant and corrosion resistant materials, such as silicone, fluororubber, etc., to ensure its stability and durability in a high temperature welding environment. At the same time, the design of the seal needs to take into account the connection form and gap size between the base 100 and the guide groove 500 to ensure that the seal can completely fill the gap and provide a good sealing effect.
[0269] According to one embodiment of the present invention, referring to Figure 1 and Figure 3 As shown, the spoiler wave generating assembly 200 and the flat wave generating assembly 300 are arranged side by side along the width direction of the base 100 .
[0270] It is understandable that, in this embodiment, the spoiler wave generating assembly 200 and the flat wave generating assembly 300 are arranged side by side in the width direction of the base 100, which can effectively utilize the space and improve the welding efficiency. At the same time, the length of the spoiler wave generating assembly 200 and the flat wave generating assembly 300 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.
[0271] In some embodiments, the spraying angles of the spoiler wave generating assembly 200 and the horizontal wave generating assembly 300 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 spraying range and speed 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 200 and the horizontal wave generating assembly 300 can 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 to effectively reduce the contact between the tin liquid and the air and reduce the oxidation rate.
[0272] According to one embodiment of the present invention, referring to Figure 3 As shown, the spoiler wave generating component 200 includes a front baffle 210, a spoiler 220 and a middle baffle 230 which are arranged in sequence; the flat wave generating component 300 includes a flat plate 310 and a rear baffle 320 which are arranged in sequence, and side panels 110 are arranged on both sides of the spoiler wave generating component 200 and the flat wave generating component 300. The front baffle 210, the spoiler 220, the middle baffle 230 and the side panels 110 enclose a spoiler cavity, and the middle baffle 230, the flat plate 310, the rear baffle 320 and the flat plate 310 enclose a flat cavity.
[0273] It can be understood that in this embodiment, the spoiler wave generating assembly 200 and the advection wave generating assembly 300 are arranged closely, that is, a spoiler cavity is formed between the front baffle 210, the spoiler 220 and the middle baffle 230, and an advection cavity is formed between the middle baffle 230, the advection plate 310 and the rear baffle 320, and the spoiler cavity and the advection cavity are separated by the middle baffle 230. 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.
[0274] In an optional embodiment, the spoiler 220 and the flat plate 310 are arranged on both sides of the middle baffle 230, and the spoiler 220 and the flat plate 310 are both in contact with the middle baffle 230, the spoiler wave generating assembly 200 and the flat wave generating assembly 300 can share the same middle baffle 230, and there is no interval between the spoiler wave generating assembly 200 and the flat wave generating assembly 300, by sharing the same middle baffle 230 and eliminating the interval between the spoiler wave generating assembly 200 and the flat wave generating assembly 300, the two assemblies can be closely combined together, reducing the additional space requirement. The overall volume of the wave soldering nozzle structure can be minimized.
[0275] 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 the wave soldering device, and ensure a good soldering effect.
[0276] According to one embodiment of the present invention, referring to Figure 3 and Figure 4 As shown, the height of the middle baffle 230 is lower than that of the rear baffle 320 so that the spoiler cavity and the advection cavity are connected.
[0277] It can be understood that in this embodiment, since there is no gap between the spoiler wave generating assembly 200 and the flat wave generating assembly 300, and by setting the height of the middle baffle 230 to be lower than the height of the rear baffle 320, the solder sprayed from the spoiler wave generating assembly 200 can flow into the flat flow cavity composed of the middle baffle 230, the flat flow plate 310 and the rear baffle 320 to a certain extent, forming a flat flow wave.
[0278] In some embodiments, the solder is directly ejected from the advection wave nozzle 301 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 301 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.
[0279] In other embodiments, the solder ejected from the spoiler wave nozzle 201 flows into the advection cavity to form a advection wave: by designing the height of the middle baffle 230 to be lower than the rear baffle 320, the solder ejected from the spoiler wave generating assembly 200 can flow into the advection cavity to form a advection wave to a certain extent. 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.
[0280] In other embodiments, a part of the advection wave is formed by the solder directly ejected from the advection wave nozzle 301 through the guide cavity, and the other part is formed by the solder ejected from the turbulent wave nozzle 201 flowing into the advection cavity, which can be designed according to actual application requirements.
[0281] In this embodiment, through the connection design between the spoiler chamber and the advection chamber, the solder ejected from the spoiler wave nozzle 201 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.
[0282] According to one embodiment of the present invention, referring to Figure 3 and Figure 4 As shown, the height of at least one of the front baffle 210 , the side panel 110 and the middle baffle 230 is adjustable.
[0283] In an optional embodiment, the height of the middle baffle 230 is adjustable. By adjusting the height of the middle baffle 230, the flow rate and speed of the solder sprayed from the turbulent wave nozzle 201 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.
[0284] On the one hand, by adjusting the height of the middle baffle 230, 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 230 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 230, 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.
[0285] In some optional embodiments, the second adjustment member 420 can be connected to the rear baffle 320 to achieve adjustable height of the rear baffle 320. By adjusting the height of the rear baffle 320, the height of the flat wave generated by the flat wave generating assembly 300 can be adjusted. At this time, the height of the middle baffle 230 can be adjusted to adapt to the height of the rear baffle 320, that is, the height of the middle baffle 230 is adaptively adjusted when the height of the rear baffle 320 is adjusted.
[0286] By adjusting the height of the rear baffle 320, the height of the advection wave generated by the advection wave generating assembly 300 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 230 also needs to be adjusted accordingly to adapt to the change in the height of the rear baffle 320. 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 320 and the middle baffle 230, more precise welding control can be achieved, and the welding quality and stability can be improved.
[0287] In an optional embodiment, the heights of the front baffle 210 , the middle baffle 230 , and the side plate 110 can be adaptively adjusted according to the height of the rear baffle 320 to meet different welding process requirements.
[0288] According to one embodiment of the present invention, referring to Figure 1 and Figure 3 As shown, the width of the spoiler 220 is greater than the width of the deflector 310 .
[0289] It is understandable that, in the present embodiment, the width of the spoiler 220 is greater than the width of the flat plate 310, so the width of the spoiler wave is also greater than the width of the flat wave, the outlet area of the spoiler wave is increased, and the larger spoiler 220 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 220 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 can flow more smoothly during the welding process, which helps to improve the uniformity and stability of the solder during the welding process, and reduces the factors that may cause welding defects. In addition, by increasing the area of the spoiler wave nozzle 201 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.
[0290] In the related art, the welding time of the turbulent wave of the wave soldering device 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.
[0291] 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.
[0292] In an optional embodiment, the first adjusting member 410 is used to adjust the angle between the spoiler wave generating assembly 200 and the base 100, and the first adjusting member 410 can adopt a spiral adjustment structure, that is, the angle between the spoiler wave generating assembly 200 and the base 100 is changed by rotating the adjusting member. This structure can provide a larger adjustment range, and the adjustment process is relatively simple.
[0293] The first adjusting member 410 may also adopt a sliding adjustment structure, that is, the angle is changed by sliding the adjusting member in a groove on the base 100. This sliding adjustment structure needs to have a certain guiding device to ensure smooth and controllable sliding.
[0294] The first adjustment member 410 may also adopt a locking nut structure, that is, the angle between the spoiler wave generating assembly 200 and the base 100 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.
[0295] In addition, the first adjusting member 410 may also adopt an adjusting pin structure, that is, the angle is changed by inserting or pulling out the adjusting pin, and this structure requires a corresponding pin groove or pin hole to fix the adjusting pin. In addition, the first adjusting member 410 may also adopt other adjusting structures, as long as it can adjust the relative angle between the spoiler wave generating assembly 200 and the base 100, and this embodiment does not specifically limit this.
[0296] 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.
[0297] 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.
[0298] 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 during welding can be changed, thereby affecting the welding effect. Adjusting the angle of the spoiler wave can make the welding effect more uniform and stable, so as to meet the requirements of the workpiece for welding quality, control the welding time and welding effect, reduce the generation of tin slag, and improve the welding quality. It has a wide range of applications and can meet the requirements of different workpieces.
[0299] In an optional embodiment, the spoiler 220 is rotated, and the spoiler wave nozzle 201 is arranged on the spoiler 220. By adjusting the angle of the spoiler 220, the angle adjustment of the spoiler wave can be achieved without adjusting the entire spoiler wave generating assembly 200. This design makes it more convenient and flexible to adjust the angle of the crest during welding. By rotating the spoiler 220, the direction and angle of the spoiler wave nozzle 201 will also change accordingly. By increasing or decreasing the angle of the spoiler 220, the spray direction of the spoiler wave nozzle 201 can be adjusted, thereby controlling the direction and shape of the solder flow during welding. The advantage of this design is that the operator only needs to simply adjust the angle of the spoiler 220 to achieve the adjustment of the spoiler wave angle during welding, without the need to make complex adjustments to the entire spoiler wave generating assembly 200, which improves the convenience and efficiency of the spoiler wave angle adjustment, and makes the adjustment of the welding parameters more intuitive and accurate.
[0300] According to one embodiment of the present invention, referring to Figure 4 As shown, the height of the front baffle 210 and the height of the spoiler 220 are both lower than the height of the middle baffle 230 .
[0301] 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 210 is set to be lower than the height of the middle baffle 230, and the spoiler 220 can be tilted toward one side of the front baffle 210, that is, the height of the spoiler 220 close to the front baffle 210 is lower than the height close to the middle baffle 230, so that the spoiler 220 can spray solder toward the front side to achieve welding.
[0302] By setting the tilt angle and height difference of the spoiler 220, the flow direction and shape of the solder during welding can be effectively controlled, and the welding efficiency and quality can be improved. 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.
[0303] According to one embodiment of the present invention, referring to Figure 3 and Figure 4As shown, the front baffle 210 includes a vertical section 211, a guide section 212 and a connecting section 213. The vertical section 211 is installed on the base 100, the guide section 212 is inclined toward the front side of the spoiler wave generating assembly 200, and the connecting section 213 connects the vertical section 211 and the guide section 212.
[0304] It can be understood that, in the present embodiment, the vertical section 211 can be mounted on the base 100 for fixing, and when the spoiler 220 sprays solder toward the front side of the spoiler wave generating assembly 200, a spoiler wave is formed to weld the circuit board, and the sprayed solder can also flow back to the tin furnace 600 under the guidance of the guide section 212. The guide section 212 guides the reflux of the solder to prevent the solder from splashing when it falls back into the tin furnace 600 and generating more tin slag. The flow direction of the solder can be effectively controlled to guide it back to the tin furnace 600 for recycling, thereby reducing waste and the generation of tin slag.
[0305] By using the inclined setting of the guide section 212 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.
[0306] According to one embodiment of the present invention, referring to Figure 3 As shown, the spoiler plate 220 is provided with spoiler wave nozzles 201 , the number of the spoiler wave nozzles 201 is multiple, and the spoiler wave nozzles 201 in two adjacent rows are staggered.
[0307] It is understandable that, in the present embodiment, the spoiler plate 220 may be provided with multiple rows of spoiler wave nozzles 201, and the spoiler wave nozzles 201 of two adjacent rows are staggered. By providing multiple spoiler wave nozzles 201, 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 201 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 turbulent 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 turbulent 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.
[0308] According to one embodiment of the present invention, referring to Figure 3 and Figure 4 As shown, a nozzle 202 is provided on the side of the spoiler wave nozzle 201 facing the circuit board to be soldered.
[0309] It is understandable that, in this embodiment, by providing the nozzle 202 at the spoiler wave nozzle 201, 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 202 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.
[0310] In the related art, in the production process of circuit boards for home appliances, 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.
[0311] According to an embodiment of the utility model, the second adjusting member 420 can adjust the height of the flat wave generating assembly 300 relative to the base 100, thereby adjusting the height of the flat wave. This design allows the height of the flat 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.
[0312] 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.
[0313] In an optional embodiment, the second adjustment member 420 can be connected to the rear baffle 320 to adjust the height of the rear baffle 320, thereby affecting the formation and flow of the entire advection wave. By adjusting the height of the rear baffle 320, the shape and size of the advection cavity can be changed, thereby adjusting the formation and height of the advection wave. This design makes it possible to adjust the parameters of the advection wave according to specific welding needs and workpiece requirements to achieve the best welding effect. Adjusting the height of the rear baffle 320 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.
[0314] In general, by adjusting the height of the rear baffle 320 through the second adjustment member 420, the formation and flow of the horizontal 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 320, the height of the horizontal 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.
[0315] According to one embodiment of the present invention, referring to Figure 3 and Figure 5 As shown, a second adjustment long hole 321 is provided on the rear baffle 320, and the second adjustment long hole 321 extends along the height direction of the advection plate 310. For example, the second adjustment long hole 321 extends obliquely upward along the height direction of the advection plate 310, and the second positioning bolt 322 is suitable for passing through the second adjustment long hole 321 and connecting with the advection plate 310 to fix the height of the rear baffle 320.
[0316] It is understandable that, in this embodiment, when the height of the rear baffle 320 needs to be changed, it is only necessary to loosen the second positioning bolt 322, move the second adjustment slot 321 to the position that needs to be adjusted, and then tighten the second positioning bolt 322 to fix the height of the rear baffle 320. Through the cooperation of the second positioning bolt 322 and the second adjustment slot 321, the height of the rear baffle 320 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.
[0317] In an optional embodiment, a positioning hole is provided on the flat plate 310, and the second positioning bolt 322 can pass through the second adjustment slot 321 and the positioning hole to achieve the installation of the rear baffle 320 on the flat plate 310. By adjusting different positions of the second adjustment slot 321 to connect with the positioning hole, the height of the rear baffle 320 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.
[0318] This design structure is simple and effective, making the installation and height adjustment of the rear baffle 320 convenient and flexible. Through reasonable adjustment, it can ensure that the connection between the rear baffle 320 and the flat plate 310 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.
[0319] In other embodiments, the second adjusting member 420 may also adopt various types of adjustment structures, as long as the height can be flexibly adjusted. In addition to the second adjustment slot 321 and the second positioning bolt 322, 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 320 can be adjusted, this application does not make any specific restrictions.
[0320] 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 second adjustment member 420, 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.
[0321] According to one embodiment of the present invention, referring to Figure 5 As shown, there are multiple second adjustment long holes 321 , and the multiple second adjustment long holes 321 are arranged at intervals along the length direction of the rear baffle 320 .
[0322] It is understandable that in this embodiment, by providing a plurality of second adjustment slots 321 on the rear baffle 320, more adjustment options and flexibility can be provided, and each second adjustment slot 321 can use a corresponding positioning bolt to fix the distance between the middle baffle 230 and the rear baffle 320. At the same time, the plurality of second adjustment slots 321 are arranged at intervals along the length direction of the rear baffle 320, so that the height adjustment of the rear baffle 320 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.
[0323] According to an embodiment of the present invention, the second adjustment slot 321 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 320 .
[0324] In an optional embodiment, scale indicator lines are arranged around the second adjustment slot 321 , and the scale indicator lines can facilitate the user to determine the height of the rear baffle 320 , thereby improving the adjustment accuracy of the height of the rear baffle 320 .
[0325] 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 320 more intuitive and convenient, especially when the height of the advection wave needs to be adjusted frequently, which can greatly improve work efficiency.
[0326] According to one embodiment of the present invention, referring to Figure 6 As shown, one of the base 100 and the side plate 110 is provided with an adjusting long hole 102 , and the other is provided with a mounting hole 101 corresponding to the adjusting long hole 102 , so that the height of the side plate 110 can be adjusted.
[0327] The height of the side plate 110 can be adaptively adjusted following the height of the rear baffle 320, and the height of the side plate 110 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. This allows the solder to flow and apply evenly during the welding process, reducing the occurrence of welding defects and improving welding quality.
[0328] It should be noted that the height of the side panel 110 may be flush with the height of the rear baffle 320 , or the height of the side panel 110 may be slightly lower than the height of the rear baffle 320 , and this embodiment does not specifically limit this.
[0329] According to one embodiment of the present invention, referring to Figure 3 As shown, the distance between the middle baffle 230 and the rear baffle 320 is adjustable.
[0330] In a specific embodiment, a first adjustment long hole 311 is provided on the advection plate 310 or the middle baffle 230, and the first adjustment long hole 311 extends along the width direction of the advection plate 310. The first positioning bolt 312 is suitable for passing through the first adjustment long hole 311 and connecting the middle baffle 230 and the advection plate 310 to fix the distance between the middle baffle 230 and the rear baffle 320.
[0331] It can be understood that in this embodiment, since the rear baffle 320 is installed on the advection plate 310, the distance between the middle baffle 230 and the rear baffle 320 can be adjusted by adjusting the relative position of the advection plate 310 and the middle baffle 230, thereby adjusting the advection wave width to meet the needs of the welding process.
[0332] In this embodiment, the first positioning bolt 312 may be a threaded connector having a length suitable for passing through the first adjustment slot 311 and connecting the middle baffle 230 and the advection plate 310 to fix the distance between the middle baffle 230 and the rear baffle 320 .
[0333] When the width of the advection wave needs to be changed, the first positioning bolt 312 only needs to be loosened by turning, and the first adjusting slot 311 needs to be moved to the position to be adjusted, and then the distance between the rear baffle 320 and the middle baffle 230 is fixed by tightening the first positioning bolt 312. Through the cooperation of the first positioning bolt 312 and the first adjusting slot 311, the distance between the rear baffle 320 and the middle baffle 230 can be easily adjusted to meet different welding requirements and workpiece characteristics.
[0334] According to one embodiment of the present invention, referring to Figure 3 As shown, there are multiple first adjustment long holes 311 , and the multiple first adjustment long holes 311 are arranged at intervals along the length direction of the advection plate 310 .
[0335] It is understandable that in this embodiment, by providing a plurality of first adjustment slots 311 on the advection plate 310, more adjustment options and flexibility can be provided, and each first adjustment slot 311 can use a corresponding positioning bolt to fix the distance between the middle baffle 230 and the rear baffle 320. At the same time, the plurality of first adjustment slots 311 are arranged at intervals along the length direction of the advection plate 310, so that the distance adjustment of each part of the advection plate 310 can be kept consistent, ensuring that the middle baffle 230 and the rear baffle 320 are parallel during the adjustment process, and ensuring the stability and consistency of the welding process.
[0336] In an optional embodiment, scale indicator lines are arranged around the first adjustment slot 311 , and the scale indicator lines can facilitate the user to determine the adjustment distance between the middle baffle 230 and the rear baffle 320 , thereby improving the adjustment accuracy.
[0337] 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 230 and the rear baffle 320 more intuitive and convenient, especially when the advection wave width needs to be adjusted frequently, which can greatly improve work efficiency.
[0338] In this embodiment, when the distance between the rear baffle 320 and the middle baffle 230 is increased, the width of the advection wave will also increase accordingly. On the contrary, when the distance between the rear baffle 320 and the middle baffle 230 is reduced, the width of the advection wave will also decrease. By adjusting the distance between the middle baffle 230 and the rear baffle 320, 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 obtain the best advection wave width according to the needs of the welding process and the expected effect.
[0339] 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.
[0340] In an alternative embodiment, reference Figure 3 and Figure 4 As shown, the middle baffle 230 is provided with a first folded edge 232, and the flat wave generating assembly 300 is also provided with a first positioning bolt 312. The first folded edge 232 and one of the flat wave plates 310 are provided with a first adjustment long hole 311, and the first adjustment long hole 311 extends along the width direction of the flat wave generating assembly 300. The first positioning bolt 312 is suitable for passing through the first adjustment long hole 311 to connect the first folded edge 232 and the flat wave plate 310, and fix the distance between the middle baffle 230 and the rear baffle 320.
[0341] The embodiment of another aspect of the present invention is as follows: Figure 1 and Fig.10 As shown, a wave soldering device is provided, including: a tin furnace 600, which is formed with a tin cavity for accommodating tin material; a wave soldering nozzle structure of any of the above embodiments, which is arranged in the tin furnace 600; and a driving component 700, which connects the tin cavity and the wave soldering nozzle structure.
[0342] In this embodiment, the tin furnace 600 is a device for melting soldering materials (such as solder such as tin), which is formed with a tin cavity for accommodating and heating the soldering materials, and the driving assembly 700 is used to control the flow and injection of the soldering materials. The driving assembly 700 is connected to the tin cavity and the wave soldering nozzle structure, and the molten soldering material is transported from the tin cavity to the wave soldering nozzle structure through a pump or other driving mechanism. The wave soldering nozzle structure is arranged in the tin furnace 600 and is connected to the driving assembly 700. The function of the wave soldering nozzle structure is to generate advection waves and turbulent waves to solder the circuit board.
[0343] The working principle of the whole device is that the driving assembly 700 extracts or pushes the molten solder material from the tin cavity into the wave soldering nozzle structure. The nozzle structure generates advection 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 to complete the soldering process of the circuit board and electronic components.
[0344] In the related art, the wave soldering nozzle structure can generate turbulent waves and flat waves to solder circuit boards. In order to reduce the generation of tin slag, the wave soldering nozzle structure is generally placed in a tin furnace 600. During operation, the temperature of the tin furnace 600 is high, the working parameters of the turbulent waves are not convenient to adjust, and the safety is poor.
[0345] According to one embodiment of the present invention, referring to Figure 1 and Figure 5 As shown, the second operating part 421 is connected to the spoiler wave generating assembly 200 through the second transmission part 422 to adjust the parameters of the spoiler wave, and the second operating part 421 is at least partially arranged outside the tin cavity. By arranging the second operating part 421 outside the tin furnace 600, the operator can directly adjust the parameters of the spoiler wave through the second operating part 421 without opening the tin furnace 600 or moving the equipment, and the operation is more convenient and quick. Since the second operating part 421 is at least partially arranged outside the tin furnace 600, the opportunity of the operator to contact high-temperature equipment can be reduced, the operation risk can be reduced, and the work safety can be improved. By adjusting the parameters of the spoiler wave outside the tin furnace 600, it can be flexibly adjusted according to different welding requirements and workpiece characteristics, meet different welding needs, and be suitable for different types of workpieces, thereby improving the versatility and flexibility of the equipment.
[0346] Exemplarily, the parameters of the disturbance wave include, but are not limited to, welding speed, welding temperature, welding pressure, welding angle and distance, etc.
[0347] According to an embodiment of the present invention, the parameter of the spoiler wave includes at least one of a cross-sectional area and a jet angle of the spoiler wave.
[0348] In this embodiment, the cross-sectional area of the spoiler wave refers to the cross-sectional area of the spoiler wave on a plane perpendicular to its propagation direction. The larger the cross-sectional area, the wider the coverage of the spoiler wave on the welding area, and the more effectively the temperature distribution and airflow of the welding area can be controlled, thereby promoting the uniform distribution and diffusion of the solder.
[0349] In an optional embodiment, a baffle (not shown in the figure) can be slidably provided above the spoiler wave generating assembly 200, the first transmission part 412 can be connected to the baffle, and the operator can drive the baffle to move through the first operating part 411 and the first transmission part 412 to adjust the size of the area of the spoiler wave generating assembly 200 covered by the baffle, so as to achieve the purpose of adjusting the cross-sectional area of the spoiler wave. In an optional embodiment, the spoiler 220 is retractable, and the spoiler 220 can be controlled to be retracted by the first transmission part 412, so as to achieve the purpose of adjusting the cross-sectional area of the spoiler wave.
[0350] Exemplarily, the parameters of the disturbance wave include, but are not limited to, welding speed, welding temperature, welding pressure, welding angle and distance, etc.
[0351] It can be understood that the parameter of the spoiler wave may include at least one of the cross-sectional area and the injection angle of the spoiler wave.
[0352] In this embodiment, the cross-sectional area of the spoiler wave refers to the cross-sectional area of the spoiler wave on a plane perpendicular to its propagation direction. The larger the cross-sectional area, the wider the coverage of the spoiler wave on the welding area, and the more effectively the temperature distribution and airflow of the welding area can be controlled, thereby promoting the uniform distribution and diffusion of the solder.
[0353] According to one embodiment of the present invention, referring to Figure 1 and Figure 7 As shown, the spoiler 220 includes a first side 221 and a second side 222 that are relatively arranged. The first side 221 is rotatably arranged on the front baffle 210 or the base 100, and the second side 222 is suitable for connecting with the first transmission part 412 to adjust the height of the second side 222 and drive the spoiler 220 to rotate.
[0354] It can be understood that, in this embodiment, the first side 221 of the spoiler 220 is rotatably disposed on the front baffle 210 or the base 100, and the height of the second side 222 can be adjusted by the transmission part, so as to drive the spoiler 220 to rotate around the first side 221, thereby achieving angle adjustment of the spoiler 220. When the height of the second side 222 of the spoiler 220 is increased by the first transmission part 412, the spray angle of the spoiler wave can be increased, and when the height of the second side 222 of the spoiler 220 is reduced by the first transmission part 412, the spray angle of the spoiler wave can be reduced, so that the height of the second side 222 can be adjusted to achieve precise control of the welding angle and welding time.
[0355] According to one embodiment of the present invention, referring to Figure 7 and Fig.10 As shown, a fixing seat 610 is installed on the tin furnace 600, and one of the first transmission part 412 and the fixing seat 610 is provided with an internal thread, and the other is provided with an external thread matching the internal thread.
[0356] It can be understood that in this embodiment, a fixing seat 610 is installed on the tin furnace 600, and the fixing seat 610 and the first transmission part 412 are connected by a threaded transmission. The threaded transmission between the internal thread and the external thread provides higher adjustment and transmission accuracy, ensuring that the angle adjustment of the spoiler 220 is more accurate and stable.
[0357] Threaded transmission generally has a higher mechanical advantage and can provide greater transmission force and higher transmission accuracy. By adjusting the first transmission part 412, the operator can easily control the inclination angle of the spoiler 220 to achieve precise adjustment of the airflow during welding, thereby optimizing welding quality and production efficiency.
[0358] In this embodiment, the fixed base 610 can also support and stabilize the first transmission part 412. By installing the fixed base 610 on the tin furnace 600 and providing threads thereon to cooperate with the first transmission part 412, it can be ensured that the first transmission part 412 can be firmly fixed on the tin furnace 600 and will not move or shake due to operation or external factors.
[0359] The support and stabilization of the fixing base 610 are crucial to the operation and adjustment of the first transmission part 412, and can ensure that the first transmission part 412 remains stable when adjusting the angle of the spoiler 220, thereby improving the accuracy and reliability of the adjustment. This design makes the adjustment of the spoiler 220 more stable during the welding process, which helps to ensure the stability and consistency of the welding quality and production efficiency.
[0360] According to an embodiment of the present invention, a scale indicator line (not shown in the figure) is provided on the first operating portion 411, and the scale indicator line is used to indicate the adjustment angle of the spoiler panel.
[0361] It is understandable that in this embodiment, through the scale indicator line, the operator can intuitively understand the inclination angle of the spoiler wave panel, and at the same time reduce the possibility of inaccurate adjustment due to errors. This design can greatly simplify the operation process, improve work efficiency, and ensure the accuracy of angle adjustment during welding. The setting of the scale indicator line makes the angle adjustment of the spoiler plate 220 more intuitive and convenient, especially when the spoiler wave angle needs to be adjusted frequently, which can greatly improve work efficiency.
[0362] According to one embodiment of the present invention, referring to Figure 1 Heat Exchange Figure 7 As shown, the second side 222 is provided with a connecting plate 240 slidably connected to the middle baffle 230, and a guide groove 241 is provided on the connecting plate 240. The first transmission part 412 is suitable for sliding along the guide groove 241 to drive the connecting plate 240 to slide along the middle baffle 230 to adjust the height of the second side 222.
[0363] It can be understood that, in this embodiment, by providing a connecting plate 240 and a guide groove 241 on the second side 222 of the spoiler 220, and a mechanism cooperating with the first transmission part 412, the height of the second side 222 can be adjusted. This design allows the operator to easily adjust the height of the second side 222 to adjust the angle of the spoiler 220.
[0364] The setting of the guide groove 241 can ensure that the first transmission part 412 moves along the predetermined track when adjusting the height of the second side 222, thereby ensuring the stability and accuracy of the adjustment. The design and connection method of the first transmission part 412 can effectively drive the connecting plate 240 to slide along the middle baffle 230 to adjust the height of the second side 222 without errors or instability due to improper operation or external factors, thereby achieving better control and optimization during the welding process.
[0365] According to one embodiment of the present invention, referring to Figure 7 and Figure 8 As shown, one of the connecting plate 240 and the middle baffle plate 230 is provided with a third adjustment long hole 242, and the other is provided with a connecting hole corresponding to the adjustment long hole 102 to realize a sliding connection between the connecting plate 240 and the middle baffle plate 230, so that the relative position between the connecting plate 240 and the middle baffle plate 230 can be flexibly adjusted while maintaining stability and reliability. By adjusting the connecting hole to connect with different positions of the third adjustment long hole 242, the height of the connecting plate 240 can be adjusted, and then the angle of the spoiler 220 can be adjusted.
[0366] In an optional embodiment, the wave soldering device also includes a connecting structure (not shown in the figure) such as a pin or a screw, and the connecting structure is passed through the mounting hole 101 and the adjustment long hole 102 to connect the connecting plate 240 and the middle baffle plate 230, thereby ensuring that the connecting plate 240 and the middle baffle plate 230 maintain a stable connection after the position adjustment.
[0367] According to one embodiment of the present invention, referring to Figure 8 and Fig. 9 As shown, the first transmission part 412 includes a transmission section 4121, a guide part 4122 and a limiting section 4123, the transmission section 4121 is connected to the first operating part 411, the first end of the guide part 4122 is connected to the transmission section 4121, the guide part 4122 is suitable for sliding along the guide groove 241, and the limiting section 4123 is connected to the second end of the guide part 4122 to limit the guide part 4122 to the guide groove 241.
[0368] It can be understood that, in this embodiment, the transmission section 4121 is used to transmit power or motion, and the transmission section 4121 is connected to the first operating part 411, and is used to convert the motion of the first operating part 411 into the motion of the transmission section 4121. The guide part 4122 is located at one end of the transmission section 4121, and its main function is to guide or control the motion direction of the transmission section 4121. The guide part 4122 is designed to slide along the guide groove 241, so that the motion direction of the transmission section 4121 can be limited, so that it moves along a specific track or path. The limiting section 4123 is connected to the other end of the guide part 4122, and its main function is to limit the moving range of the guide part 4122 in the guide groove 241 to ensure the stability and reliability of the transmission device. The limiting section 4123 can fix the guide part 4122 at a specific position of the guide groove 241 to prevent excessive movement or dislocation, and ensure that the transmission section 4121 can achieve the height adjustment of the connecting plate 240 when moving back and forth, thereby adjusting the angle of the spoiler 220.
[0369] Exemplarily, the cross-sectional areas of the transmission section 4121 and the limiting section 4123 are both larger than the cross-sectional area of the guide portion 4122 to better achieve limiting.
[0370] According to an embodiment of the utility model, the spoiler 220 and the connecting plate 240 are an integrated structure to ensure that the spoiler 220 and the connecting plate 240 can work together better to reduce looseness and vibration during transmission, thereby improving the stability of the transmission while improving the overall strength and durability.
[0371] In the related art, the wave soldering nozzle structure can generate turbulent waves and flat waves to solder the circuit board. In order to reduce the generation of tin slag, the wave soldering nozzle structure is generally placed in a tin furnace 600. During operation, the temperature of the tin furnace 600 is relatively high, and the height of the flat wave is not convenient to adjust, which can easily lead to unstable welding quality and affect welding efficiency.
[0372] According to one embodiment of the present invention, referring to Figure 1 As shown, the second operating part 421 is at least partially arranged outside the tin furnace 600, and the operator can directly adjust the height of the advection wave through the second operating part 421 without opening the tin furnace 600 or moving the equipment, which makes the operation more convenient and quick. Since the second operating part 421 is at least partially arranged outside the tin furnace 600, the operator can reduce the chance of contact with high-temperature equipment, reduce the operating risk, and improve work safety. The height of the advection wave generating assembly 300 can be accurately controlled by the second transmission part 422, so as to achieve accurate adjustment of the advection wave height and improve welding quality and production efficiency. By adjusting the height of the advection wave outside the tin furnace 600, it can be flexibly adjusted according to different welding requirements and workpiece characteristics, meet different welding needs, and be suitable for different types of workpieces, thereby improving the versatility and flexibility of the equipment.
[0373] It should be noted that the structure of the second transmission part 422 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 320.
[0374] In an optional embodiment, the second transmission part 422 adopts 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 320 can be slightly adjusted, which is suitable for occasions requiring higher precision.
[0375] In another optional embodiment, the second transmission part 422 adopts a screw drive, which uses the spiral side effect of the nut and the screw to convert the rotational motion into linear displacement, thereby realizing the precise adjustment of the height of the rear baffle 320. The screw drive has high transmission efficiency and precision, and is suitable for occasions that require precise adjustment. In another optional embodiment, the second transmission part 422 adopts a hydraulic drive, which transmits pressure through the hydraulic system to achieve motion control, and can achieve precise adjustment of the height of the rear baffle 320 by precisely controlling the movement of the hydraulic cylinder, which is suitable for large equipment and occasions that require high-power transmission. In another optional embodiment, the second transmission part 422 adopts a chain drive, which uses the cooperation of the chain and the gear to transmit motion and force, and can achieve a relatively stable and reliable transmission to adjust the height of the rear baffle 320.
[0376] In this embodiment, the second operating part 421 can be designed as a handle, a knob or other structure. In an optional embodiment, the second transmission part 422 can be controlled to move by rotating or pushing and pulling the handle, thereby adjusting the height of the rear baffle 320. The handle operation is simple and intuitive, and can be applied to occasions where the height of the rear baffle 320 needs to be frequently adjusted. In another optional embodiment, the second transmission part 422 can be controlled by rotating the knob, thereby adjusting the height of the rear baffle 320. 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.
[0377] The structure of the first transmission part 412 may be similar to that of the second transmission part 422 , and will not be described in detail in this embodiment.
[0378] According to one embodiment of the present invention, referring to Figure 1 , Figure 4 and Figure 5As shown, a guide groove 241 is formed at one end of the rear baffle 320, and the second transmission part 422 includes a transmission screw, and one end of the transmission screw is passed through the guide groove 241, and the other end is connected to the second operating part 421. When the second operating part 421 rotates, it is suitable for driving the transmission screw to slide up and down relative to the guide groove 241 to adjust the height of the rear baffle 320.
[0379] It is understandable that in this embodiment, the operator can drive the second transmission part 422 to move by rotating the second operating part 421 (such as a handle, a knob, etc.), and when the second operating part 421 rotates, the transmission screw will slide up and down along the guide groove 241. The movement of the transmission screw will drive the rear baffle 320 connected thereto, thereby realizing the adjustment of the height of the rear baffle 320.
[0380] As required, the operator can gradually rotate or push and pull the second operating part 421 to fine-tune the height of the rear baffle 320 until the requirements are met without using complex tools or performing cumbersome operations. The advantage of this adjustment method is that it is easy to operate, and the height of the rear baffle 320 can be adjusted by sliding the drive screw up and down, which can achieve high precision. At the same time, the existence of the guide groove 241 can ensure the stability of the drive screw in the vertical direction, avoid the deflection or shaking of the rear baffle 320 during the height adjustment process, and thus ensure the stability of the rear baffle 320 during the height adjustment process.
[0381] In the related art, the wave soldering device sprays molten tin liquid to form a wave crest to solder the circuit board. The sprayed tin liquid will directly fall back into the tin furnace 600. Due to the large height difference of the falling tin liquid, it will produce a large impact and splash, which can easily cause vibration and instability in the welding process, affecting the welding quality.
[0382] According to one embodiment of the present invention, referring to Figure 3 and Fig.10 As shown, the tin furnace 600 is formed with a containing cavity for containing tin liquid, and the wave soldering nozzle structure is also provided with a guide component 800 , which is suitable for guiding the tin liquid sprayed out of the wave soldering nozzle structure back to the tin furnace 600 .
[0383] The flow guide component 800 can be arranged at the lower side of the disturbance wave generating component 200 or the flat wave generating component 300 to effectively guide the ejected tin liquid back to the tin furnace 600 to achieve buffering. In some embodiments, the height of the flow guide component 800 is between the height of the disturbance wave generating component 200 and the liquid level height of the tin furnace 600, so as to achieve buffering for the tin liquid ejected from the disturbance wave generating component and prevent the tin liquid from falling directly into the tin furnace 600. By setting the flow guide component 800 to guide the tin liquid back to the tin furnace 600, the problem of large impact force generated by the direct fall of the tin liquid can be effectively solved, thereby improving the stability during the welding process, making the welding process more stable and reliable, and reducing the adverse effects on the welding quality.
[0384] According to one embodiment of the present invention, referring to Figure 3 and Fig.10 As shown, the guide component 800 is arranged side by side with the wave soldering nozzle structure, the guide component 800 is at least partially arranged below the wave soldering nozzle structure, and the guide component 800 is formed with a guide hole 801, which is connected to the accommodating cavity.
[0385] It can be understood that, in this embodiment, the flow guide component 800 is arranged side by side with the wave soldering nozzle structure, for example, the flow guide component 800 can be arranged side by side with the length direction of the wave soldering nozzle structure, which can ensure that the tin liquid sprayed from the wave soldering nozzle structure can be effectively guided through the flow guide component 800. This design can make the most of the flow guide component 800, and ensure that the flow guide component 800 covers the entire length of the wave soldering nozzle structure as much as possible, and the sprayed tin liquid will be guided by the flow guide component 800. In this way, no matter where the welding material is sprayed, it can be timely received and guided by the flow guide component 800, achieving the effect of full-course guidance.
[0386] In some embodiments, the guide component 800 is a trough structure, and a guide hole 801 is provided on the guide component 800, and the guide hole 801 is connected to the containing cavity. The tin liquid sprayed out of the wave soldering nozzle structure can fall back into the containing cavity of the tin furnace 600 through the guide hole 801. The design of the guide hole 801 further realizes the buffering of the tin liquid, further reduces the impact force generated when the tin liquid falls back to the tin furnace 600, and improves the stability and reliability of the welding process.
[0387] According to one embodiment of the present invention, referring to Figure 3 As shown, there are multiple flow guide holes 801 , and the multiple flow guide holes 801 are arranged along the length direction of the flow guide component 800 , or the multiple flow guide holes 801 are arranged in an array in the flow guide component 800 .
[0388] It is understandable that in this embodiment, multiple guide holes 801 are arranged along the length direction of the guide component 800, or multiple guide holes 801 are arranged in an array in the guide component 800, which can effectively achieve the diversion and reflux of the tin liquid. This design can more evenly distribute the flow of the soldering material, improve the diversion effect and reflux efficiency, ensure that the tin liquid is fully guided and returned to the accommodating cavity of the tin furnace 600, and promote the reflux and circulation of the solder.
[0389] If multiple guide holes 801 are arranged along the length direction of the guide component 800, the flow of the tin liquid can be evenly controlled during the entire welding process, thereby improving the welding quality and stability. If multiple guide holes 801 are arranged in an array on the guide component 800, the flow path of the welding material can be more accurately controlled, further improving the guide effect and the accuracy of the reflow.
[0390] In this embodiment, the size and number of the guide holes 801 need to be reasonably designed according to the specific welding parameters and equipment characteristics. The through holes can be evenly distributed in the length and width directions of the tin slag collection trough to ensure that the reflux of the solder is evenly distributed to avoid local accumulation or excessive flow.
[0391] According to one embodiment of the present invention, referring to Figure 3 As shown, at least one of the spoiler wave generating assembly 200 and the flat wave generating assembly 300 is provided with a flow guiding assembly 800 .
[0392] It is understandable that in this embodiment, at least one of the generating components (the spoiler wave generating component 200 or the flat wave generating component 300) is provided with a flow guide component 800 for guiding the flow of the welding material and realizing the flow guide and reflux functions during the welding process. By providing the flow guide component 800, the flow path of the welding material can be effectively controlled to ensure that the welding material is correctly guided and returned to the receiving chamber of the welding equipment. This design can improve the stability and consistency of the welding process, reduce the waste of welding materials, and ensure that the welding quality meets the standard requirements.
[0393] In an optional embodiment, both the spoiler wave generating component 200 and the peaceful wave generating component 300 are provided with a guide component 800, which can fully guide the tin liquid of the spoiler wave and peaceful wave to ensure the quality stability of spoiler wave welding and peaceful wave welding.
[0394] According to one embodiment of the present invention, referring to Figure 3As shown, the guide groove 800 includes a first guide groove 810 and a second guide groove 820, the spoiler wave generating component 200 and the flat wave generating component 300 are arranged side by side, the first guide groove 810 is arranged on one side of the spoiler wave generating component 200, the second guide groove 820 is arranged on one side of the flat wave generating component 300, and the first guide groove 810 and the second guide groove 820 are arranged side by side.
[0395] It is understandable that when soldering a circuit board, spoiler wave soldering is usually performed first through the spoiler wave generating component 200, and then through the flat wave soldering component 300. In this embodiment, a first guide groove 500 is provided on the front side of the spoiler wave generating component 200, and a second guide groove 820 is provided on the rear side of the flat wave generating component 300. The first guide groove 810 can reduce the tin discharge impact on the front side of the spoiler wave nozzle 202, so that the welding process is smoother and continuous; the second guide groove 820 can reduce the tin discharge impact on the rear side of the flat wave nozzle 202, so that the welding process is smoother and continuous, thereby reducing tin oxide and ensuring welding quality and reliability.
[0396] In an optional embodiment, the height of the second guide groove 820 near the flat wave generating assembly 300 is lower than the height away from the flat wave generating assembly 300, and the guide hole 801 is arranged at the end of the second guide groove 820 near the flat wave generating assembly 300 to improve the efficiency of solder reflux.
[0397] According to an embodiment of the present invention, the height of at least one of the first guide groove 810 and the second guide groove 820 is adjustable.
[0398] In an optional embodiment, the height of the first guide groove 810 is adjustable. In another optional embodiment, the height of the second guide groove 820 is adjustable. In another optional embodiment, the heights of both the first guide groove 810 and the second guide groove 820 are adjustable.
[0399] In this embodiment, by adjusting the height of the first guide groove 810 or the second guide groove 820, the impact force of the molten tin of the disturbance wave or the flat wave falling back to the tin furnace 600 can be adjusted, the reflux effect of the molten tin during welding is optimized, the generation of splashing and bubbles is reduced, and the welding quality and stability are improved. This adjustment method can be flexibly adjusted according to specific welding requirements and workpiece characteristics to obtain the best welding effect.
[0400] For example, in some embodiments, the height of the first guide groove 810 or the second guide groove 820 can be adaptively adjusted according to the height of the wave soldering nozzle structure and the liquid level of the tin furnace 600, so as to achieve sufficient buffering of the tin liquid and reduce the impact force, thereby improving the stability and quality during the welding process. By adjusting the height of the guide groove 500 according to the height of the wave soldering nozzle structure and the liquid level of the tin furnace 600, it can be ensured that the tin liquid is properly buffered and controlled when it flows back to the tin furnace 600, reducing the impact of the impact force on the equipment and welding quality. This adaptive adjustment design can be flexibly adjusted according to specific welding conditions and requirements, making the welding process more stable and controllable, better suitable for different welding processes and requirements, and improving the success rate and efficiency of welding. At the same time, reducing the impact force when the tin liquid flows back also helps to reduce material loss and equipment wear during the welding process and extend the service life of the equipment.
[0401] Specifically, the height adjustment method of the first guide groove 810 and the second guide groove 820 can be manual adjustment, for example, the operator can adjust the height of the guide groove 500 by manually rotating bolts or levers. The height of the guide groove 500 can also be automatically adjusted by a motor drive structure. The height adjustment of the guide groove 500 can also be achieved by using pneumatic devices or hydraulic systems. It can be selected according to specific adjustment requirements, and this embodiment does not make specific limitations on this.
[0402] In some other optional implementations, the inclination angle of the first guide groove 810 or the second guide groove 820 can also be adjusted as needed, so that it can be fully adapted to different application scenarios. The specific adjustment method is not specifically limited in this embodiment.
[0403] According to one embodiment of the present invention, referring to Figure 3 As shown, the spoiler wave generating assembly 200 includes a front baffle 210, a spoiler 220 and a middle baffle 230 which are arranged in sequence, a spoiler cavity is formed between the front baffle 210, the spoiler 220 and the middle baffle 230, and the front baffle 210 is provided with a guide surface 214, which is inclined toward the direction of the first guide groove 810.
[0404] It can be understood that in the present embodiment, a spoiler cavity is formed between the front baffle 210, the spoiler 220 and the middle baffle 230, and a spoiler wave nozzle 201 is provided on the spoiler 220, which can generate a spoiler wave, and the guide surface 214 is inclined toward the direction of the first guide groove 810. Due to the inclined design of the guide surface 214, the tin liquid will be guided to flow in the direction of the first guide groove 810, reducing unnecessary impact and violent flow, and finally flowing back to the tin furnace 600, which can achieve the effect of buffering and reducing impact of the tin liquid, and help to improve the welding quality and protect the welding equipment.
[0405] In the related art, the turbulence wave generating component 200 and the horizontal wave generating component 300 of the wave soldering device are independently arranged and are driven separately by turbulence pumps and horizontal flow pumps respectively. The turbulence pump drives the tin liquid in the tin furnace 600 to eject from the turbulence wave nozzle 201 to form turbulence waves. The turbulence wave nozzle 201 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 600 to eject from the horizontal wave nozzle to form horizontal waves. The horizontal wave nozzle 301 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.
[0406] According to one embodiment of the present invention, referring to Figure 1 and Fig.10 As shown, there is one flow guide cavity and one driving assembly 700, both the spoiler wave generating assembly 200 and the calm wave generating assembly 300 are connected to the flow guide cavity, and the driving assembly 700 is suitable for driving the tin liquid from the tin furnace 600 to flow to the spoiler wave generating assembly 200 and the calm wave generating assembly 300 to generate spoiler waves and calm waves.
[0407] In this embodiment, it is easy to understand that the number of the guide cavity is one, and the spoiler wave generating assembly 200 and the peaceful wave generating assembly 300 are both connected to the guide cavity, so that the spoiler wave generating assembly 200 and the peaceful wave generating assembly 300 can be integrated on the same base 100. 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 spoiler wave and the peaceful wave can be more conveniently controlled, and the convenience and flexibility of operation are improved; the spoiler wave and the peaceful wave can work at the same time and coordinate with each other, thereby improving the stability and efficiency of the welding process, and the spoiler wave generating assembly 200 and the peaceful wave generating assembly 300 are integrated on the same base 100 to save space and reduce the overall volume.
[0408] The spoiler wave nozzle 201 and the flat wave nozzle 301 are both connected to the guide cavity. The spoiler wave nozzle 201 and the flat wave nozzle 301 can be used for welding by only one driving motor to transport the solder into the guide cavity, thereby realizing the integration of the spoiler wave and the flat wave, that is, the spoiler wave component and the flat wave component can work at the same time, 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 200 and the flat wave generating component 300 to work separately, the energy consumption is reduced and the production cost is reduced.
[0409] Since the operation of the spoiler wave generating component 200 and the horizontal wave generating component 300 can be realized by a driving component 700, compared with the previous design in which the spoiler wave generating component 200 and the horizontal wave generating component 300 are independently driven by a driving motor, one driving motor, an impeller, a frequency converter, a guide groove 500 and a base 100 can be reduced, thereby greatly saving the manufacturing cost and maintenance cost of the wave soldering device.
[0410] 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.
