[0043] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners adopt related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods.

For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0044] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner that is obvious to those skilled in the art.

[0045] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0046] In currently common soldering machines, the tin feeding module 400 is usually arranged on the soldering frame 200. During the soldering operation, the soldering module 500 moves driven by the moving module 300, and the tin feeding module 400 supplies tin to the soldering module 500 that moves to various places through the tin delivery pipe 4241. Since the position of the soldering module 500 changes continuously, the shape of the tin delivery pipe 4241 also changes accordingly, which easily hinders the transportation of the solder wire along the tin delivery pipe 4241; moreover, due to the relatively long distance between the soldering module 500 and the tin feeding module 400, the length of the tin delivery pipe 4241 is relatively long, and the frictional resistance during transportation is relatively large, which is not conducive to the transportation of the solder wire, especially for the transportation of small-diameter solder wires with a diameter of 0.5 mm, and the transportation quality is not good.

[0047] In the embodiment of the present application, the tin feeding module 400 and the soldering module 500 are integrally arranged on the mounting member 600, and by setting a positioning structure, the tin feeding module 400 can be stably arranged on the mounting member 600 so as to move together with the soldering module 500 driven by the moving module 300. This not only helps the tin delivery pipe 4241 to maintain a stable state and helps to avoid the influence of the deformation of the tin delivery pipe 4241 on the transportation of the solder wire, but also can shorten the tin feeding distance, reduce the frictional resistance during the transportation of the solder wire, and achieve the effect of improving the tin feeding quality.

[0048] An embodiment discloses a soldering machine. Please refer to Figures 1-5 , the soldering machine includes a soldering frame 200, a moving module 300, a tin feeding module 400, and other modules or structures set as needed.

[0049] In one embodiment, taking a four-axis soldering machine as an example, please refer to Figure 1 , the soldering machine further includes a machine base 100, the soldering frame 200 is arranged on the machine base 100, and the moving module 300 is arranged on the soldering frame 200.

[0050] Exemplarily, please refer to Figure 1, the machine base 100 has a length direction. Along the length direction of the machine base 100, a Y-axis guide rail 110 is provided. A moving platform 120 is arranged on the Y-axis guide rail 110. The Y-axis guide rail 110 is used to drive the moving platform 120 to move along the length direction of the Y-axis guide rail 110. Workpieces such as PCB boards are placed on the moving platform 120. The soldering frame 200 is a gantry frame. The soldering frame 200 includes columns 210 arranged on both sides of the machine base 100 and a cross beam 220 erected between the two columns 210.

[0051] The moving module 300 includes an X-axis guide rail 310 arranged on the cross beam 220 along the length direction of the cross beam 220, and a Z-axis mechanism 320 arranged on the X-axis guide rail 310. The X-axis guide rail 310 is used to drive the Z-axis mechanism 320 to move along the length direction of the X-axis guide rail 310. The Z-axis mechanism 320 includes a housing 321 and a Z-axis guide rail and an R-axis mechanism arranged in the housing 321. The Z-axis guide rail is used to drive the R-axis mechanism to move along the length direction of the Z-axis guide rail. The X-axis guide rail 310, the Y-axis guide rail 110, and the Z-axis guide rail can be perpendicular to each other. The R-axis mechanism includes an R-axis driving member and an R-axis 330. The R-axis 330 is arranged along the Z-axis guide rail direction. One end of the R-axis 330 close to the machine base 100 extends out of the housing 321. The R-axis driving member is used to drive the R-axis 330 to rotate. The Z-axis guide rail and the R-axis driving member are not shown in the figure.

[0052] In other embodiments, the soldering machine can also be other types of soldering machines. The machine base 100, the soldering frame 200, and the moving module 300 can also adopt other setting forms. For example: the moving module 300 can only include the X-axis guide rail 310 and the Z-axis guide rail, or the Y-axis guide rail 110 is used to drive the soldering frame 200 to move along the length direction of the Y-axis guide rail 110.

[0053] In one embodiment, please refer to Figure 1 and Figure 2, an installation member 600 is provided on the moving module 300, and a solder feeding module 400 and a soldering module 500 are provided on the installation member 600. Among them, the solder feeding module 400 includes a solder wire bracket 410 and a solder feeding unit 420. Both the solder wire bracket 410 and the solder feeding unit 420 are provided on the installation member 600. The solder wire bracket 410 is used to install a solder wire coil. The solder feeding unit 420 includes a tin feeding pipe 4241, and the solder feeding unit 420 is used to convey the solder wire to the soldering area of the soldering module 500 through the tin feeding pipe 4241. Integrating the solder feeding module 400 and the soldering module 500 on the installation member 600 helps to shorten the solder feeding distance, reduce the frictional resistance during the solder wire conveying process; and can avoid the frequent deformation of the tin feeding pipe 4241 during the soldering operation, keep the tin feeding pipe 4241 in a stable form, help to avoid the influence of the deformation of the tin feeding pipe 4241 on the solder wire conveying, and achieve the effect of improving the solder feeding quality. In addition, it also helps to improve the overall compactness of the soldering machine and save the installation space. And shortening the solder feeding distance also helps to improve the applicability of the soldering machine to small-diameter solder wires such as those with a diameter of 0.5 mm.

[0054] For a four-axis soldering machine with an R axis 330, the installation member 600 is arranged on the R axis 330. Since the R axis mechanism can rotate freely by 360°, the soldering module 500 can be adjusted at any angle and in any orientation to realize soldering at any solder joint position in the 3D space.

[0055] Exemplarily, please refer to Figure 2 , the installation member 600 includes a first part 610 and a second part 620. The first part 610 is provided with a shaft-passing hole (not shown in the figure) for the R axis 330 to pass through. The first part 610 is provided with a recess. The second part 620 can be clamped at the recess. And semi-circular cavities (not shown in the figure) are provided on the opposite side walls of the second part 620 and the first part 610. The two semi-circular cavities can be combined into a locking shaft cavity that is aligned and communicated with the shaft-passing hole. When the second part 620 is fixed to the first part 610 by bolts, the R axis 330 in the locking shaft cavity can be locked, so that the installation member 600 is fixed to the R axis 330. In other embodiments, the installation member 600 can also be arranged on the Z-axis guide rail as needed.

[0056] In one embodiment, please refer to Figure 2 and Figure 3 , the installation member 600 has a first side and a second side arranged oppositely. The first side is used to install the soldering module 500, and one of the solder wire bracket 410 and the solder feeding unit 420 is installed on the second side. By respectively arranging the soldering module 500 and one of the solder wire bracket 410 and the solder feeding unit 420 on the opposite sides of the installation member 600, it helps to balance the force on the installation member 600 and facilitate the installation member 600 to maintain stability during movement.

[0057] In one embodiment, please refer to Figure 2 and Figure 3 , a solder wire bracket 410 is installed on the second side. The mounting member 600 further has a third side, which is disposed opposite to the second side, and the solder feeding unit 420 is disposed on the third side. Exemplarily, the mounting member 600 is generally in a cuboid structure, and the soldering module 500 and the solder feeding unit 420 are respectively located at the diagonal positions of the mounting member 600. The solder feeding bracket is located at a corner of the mounting member 600 adjacent to both the soldering module 500 and the solder feeding unit 420. With such an arrangement, there is no other module blocking between the welding area of the solder feeding unit 420 and the soldering module 500, so that the solder wire can be directly sent to the welding area of the soldering module 500 after being sent out by the solder feeding unit 420, which helps to reduce the conveying distance of the solder wire and also reduces bending, contributing to improving the conveying quality.

[0058] In other embodiments, the solder feeding unit 420 can also be disposed on the second side, the solder wire bracket 410 can be disposed on the third side, or the soldering module 500, the solder wire bracket 410 and the solder feeding unit 420 can be arranged in other ways, as long as the design and use requirements can be met.

[0059] In order to enable the welding angle of the welding module to be adjusted according to the welding requirements of the product, in one embodiment, please refer to Figure 2 and Figure 3 , an angle adjusting mechanism 630 is provided on the mounting member 600, and the angle adjusting mechanism 630 is used for movably arranging the soldering module 500 on the mounting member 600.

[0060] In one embodiment, the angle adjusting mechanism 630 includes an angle adjusting member 632, a fixing member 633 and two limiting members 631. Among them, the two limiting members 631 are spaced apart on the mounting member 600, and arc surfaces are provided on the opposite sides of the two limiting members 631 to form an arc-shaped limiting groove 6311 between the two limiting members 631; the angle adjusting member 632 includes a connecting portion 6321 and a matching portion 6322, the matching portion 6322 is set to be arc-shaped and adapted to the radian of the arc-shaped limiting groove 6311, the matching portion 6322 is slidably disposed in the arc-shaped limiting groove 6311, and the connecting portion 6321 is used for installing the soldering module 500; the fixing member 633 is used for fixing the angle adjusting member to the mounting member 600. When the welding angle of the welding module needs to be adjusted, first release the fixing of the fixing member 633, and then slide the angle adjusting member 632 along the arc-shaped limiting groove 6311, so that the welding module can be deflected and the welding angle can be changed. After the adjustment is in place, reinstall the fixing member 633 for fixing.

[0061] Exemplarily, please refer to Figure 2 and Figure 3, two limit members 631 are axially spaced along the R axis 330 on one side of the mounting member 600. Threaded holes (not shown in the figure) are provided in pairs on the mounting member 600 between the two limit members 631; a plurality of groups of fixing holes 63221 are spaced along the arc direction of the mating portion 6322 itself, and two fixing holes 63221 in each group are provided corresponding to the threaded holes. When the mating portion 6322 slides in the arc-shaped limit groove 6311, the fixing holes 63221 can be aligned with the two threaded holes group by group; the fixing member 633 is a fixing bolt. After the mating portion 6322 is slid and adjusted to the required position, the fixing bolt is passed through the fixing hole 63221 and threadedly connected to the threaded hole to complete the fixing.

[0062] In other embodiments, one, three or more threaded holes can also be provided, and the fixing holes 63221 can be provided to match the threaded holes; the fixing member 633 can also be a fixing pin, a clamping plate or other positioning structures, and the fixing holes 63221 and the threaded holes can be replaced with other mating structures according to the different fixing members 633, and the fixing of the mating portion 6322 and the mounting member 600 can be realized.

[0063] In one embodiment, please refer to Figure 3 , the solder wire support 410 includes a support rod 411 mounted on the mounting member 600. The support rod 411 is used for sleeving the solder wire coil. A limit stop 412 is provided at one end of the support rod 411 away from the mounting member 600. The limit stop 412 can be detachably mounted on the support rod 411 by bolts. The limit stop 412 is used for limiting the solder wire coil mounted on the support rod 411 to prevent the solder wire coil from shifting when the user detaches it. In other embodiments, the solder wire support 410 can also adopt other structures, and can be used for mounting and fixing the solder wire coil or other types of solder wires.

[0064] Since the solder feeding unit 420 will generate offset inertia when moving with the moving module 300, it is easy to cause the solder feeding unit 420 to have a position deviation, which affects the solder feeding quality. For this, in one embodiment, please refer to Figure 3 and Figure 4 , the mounting member 600 is provided with a mounting portion 640. The solder feeding unit 420 includes a solder feeding support plate 421. The mounting portion 640 and the solder feeding support plate 421 are provided with a matching positioning structure, and the mounting portion 640 and the solder feeding support plate 421 are detachably connected by a fastener 4211. By setting the positioning structure to cooperate with the fastener 4211 for fixing, the solder feeding unit 420 can be stably fixed on the mounting member 600, so that the solder feeding unit 420 can adapt to the mobile solder feeding scenario, which helps to realize the stable movement of the solder feeding unit 420 along with the mounting member 600, so that the tin delivery pipe 4241 can maintain a relatively stable state during tin delivery, and helps to avoid fluctuations in the solder feeding quality.

[0065] In one embodiment, please refer to Figure 3 andFigure 4 The positioning structure includes a transverse groove 641 provided on the mounting portion 640, and one side of the tin feeding bracket plate 421 is inserted into the transverse groove 641. Not only is the structure simple, but the positioning operation is also convenient. For example, the mounting portion 640 is a plate-shaped structure, and the mounting portion 640 is fixed on the mounting member 600 by bolts. The transverse groove 640 is provided on the side of the mounting portion 640 away from the mounting member 600, and the transverse groove 641 is provided perpendicular to the R-axis 330. The thickness of the tin feeding bracket plate 421 is adapted to the width of the transverse groove 641, and one side of the tin feeding bracket plate 421 is inserted into the transverse groove 641.

[0066] Regarding the fixing method of the fastener 4211, in some embodiments, a mounting hole that passes through the mounting portion 640 can be provided at the position corresponding to the transverse groove 641 on the mounting portion 640, and the portion of the tin feeding bracket plate 421 inserted into the transverse groove 641 can be provided with a threaded hole. The fastener 4211 can be a bolt or a screw, and the fastener 4211 passes through the mounting hole and is threadedly connected to the threaded hole to fix the tin feeding bracket plate 421, thereby fixing the tin feeding unit 420. The provision of the transverse groove 641 not only facilitates the positioning of the tin feeding unit 420, but also helps to install and fix the tin feeding unit 420. In other embodiments, the positioning structure can also be a positioning block provided on the mounting portion 640 or other structure that meets the design and use requirements.

[0067] In one embodiment, please refer to Figure 4 and Figure 5 The tin delivery unit 420 also includes a tin delivery box 422, a tin inlet guide tube 423, a tin outlet conduit 424, and a tin delivery assembly.

The outlet end of the tin outlet conduit 424 is connected to the tin delivery tube 4241. The tin delivery assembly is mounted between the tin inlet guide tube 423 and the tin outlet conduit 424 to provide power for the tin wire. The tin inlet guide tube 423 and the tin outlet conduit 424 cooperate to form a tin wire delivery path. The tin delivery assembly applies power to the tin wire along the tin wire delivery path, allowing the tin wire to be continuously delivered along the tin delivery tube 4241 after entering the tin delivery tube 4241.
