[0031] Please refer to Figure 1 and Figure 2 , to solve the problem of low stability of the welding structure after welding by a soldering machine, the present invention proposes a soldering machine 1000, including:

[0032] A frame 1 and a welding mechanism, the frame 1 having a welding station 11; the welding mechanism includes two soldering modules 21, both of the two soldering modules 21 are provided on the frame 1 and are respectively located on both sides of the welding station 11; each soldering module 21 includes a soldering device 211, a moving component, and two voice coil motors 213, the moving component includes a first longitudinal moving slide rail 2121, a first longitudinal moving slide block 2122, a transverse moving slide rail 2123, and a transverse moving slide block 2124, the straight line along which the first longitudinal moving slide rail 2121 extends and the straight line along which the transverse moving slide rail 2123 extends are perpendicular to each other, the transverse moving slide rail 2123 is provided on the first longitudinal moving slide block 2122; one voice coil motor 213 is provided on the first longitudinal moving slide rail 2121 and drives the first longitudinal moving slide block 2122 to move on the first longitudinal moving slide rail 2121; the other voice coil motor 213 is provided on the first longitudinal moving slide block 2122 and drives the transverse moving slide block 2124 to move on the transverse moving slide rail 2123. In the technical solution of the present invention, the driving accuracy of the voice coil motor 213 is high. Using the voice coil motor 213 to drive the first longitudinal moving slide block 2122 and the transverse moving slide block 2124 to move can accurately move the soldering device 211 to the welding positions on both sides of the welding station 11, thereby improving the welding accuracy of the soldering machine 1000, reducing the welding thickness difference on both sides of the PCB board a, and improving the stability of the welding structure; at the same time, since the moving speed of the voice coil motor 213 is fast, the working efficiency of the soldering machine 1000 can be improved.

[0033] In an embodiment, the soldering machine 1000 further includes a feeding mechanism, the feeding mechanism includes a conveying line 31 and a loading device, both the conveying line 31 and the loading device are provided on the frame 1, and the conveying line 31 has a loading station 311; the conveying line 31 is used to convey the PCB board a to the loading station 311, and the loading device is used to move the PCB board a on the loading station 311 to the welding station 11. The cooperation of the loading device and the conveying line 31 realizes automatic loading, improves the loading efficiency, and is convenient for the user to use.

[0034] The loading device can be a loading robot or a moving component composed of a slide rail and a slide block. In an embodiment, the loading device includes a loading component and a loading suction plate 322, the loading component includes a second longitudinal moving slide rail 3211, a second longitudinal moving slide block 3212, and a first vertical moving slide block 3213, and the second longitudinal moving slide block 3212 is formed with a first vertical moving slide rail; the second longitudinal moving slide rail 3211 is provided on the frame 1, the second longitudinal moving slide block 3212 is slidably connected to the second longitudinal moving slide rail 3211, the first vertical moving slide block 3213 is slidably connected to the first vertical moving slide rail, the loading suction plate 322 is connected to the first vertical moving slide block 3213, and the loading suction plate 322 is used to suck the PCB board a. The first vertical moving slide block 3213 drives the loading suction plate 322 to move vertically, and the second longitudinal moving slide block 3212 drives the first vertical moving slide block 3213 to move longitudinally, realizing the operation of moving the PCB board a from the loading station 311 to the welding station 11, and improving the loading efficiency.

[0035] The loading suction plate 322 can be fixedly connected to the first vertical moving slider 3213 or rotatably connected to the first vertical moving slider 3213. In an embodiment, the loading suction plate 322 is rotatably connected to the first vertical moving slider 3213. The loading process is a process of transferring the PCB board a from the loading station 311 to the welding station 11. Since the length direction of the loading station 311 may not be consistent with the length direction of the welding station 11, and the loading suction plate 322 is rotatably connected to the first vertical moving slider 3213, the loading suction plate 322 can rotate to adjust the orientation of the PCB board a to adapt to more diverse application scenarios. Therefore, it is preferred that the loading suction plate 322 is rotatably connected to the first vertical moving slider 3213.

[0036] In an embodiment, the conveyor line 31 further has an unloading station 312; the conveyor line 31 is used to send the PCB board a on the unloading station 312 away from the frame 1; the feeding mechanism further includes an unloading device, and the unloading device includes a third longitudinal moving slide rail 331, a third longitudinal moving slider 332, a second vertical moving slider 333 and an unloading suction plate 334.

The cooperation of the unloading device and the conveyor line 31 realizes automatic unloading, improves the unloading efficiency, and facilitates the use of the user.

[0037] After welding, it may be inconvenient to unload due to the obstruction of the welding equipment. To solve this problem, in an embodiment, the soldering machine 1000 further includes a turntable 4. The turntable 4 is rotatably provided on the frame 1, and the turntable 4 has a bearing surface 41 for bearing the PCB board a. After welding, the user can rotate the turntable 4 to turn the welded PCB board a away from the welding station 11, thereby facilitating the unloading of the welded PCB board a.

[0038] In one embodiment, the frame 1 further has a pre-welding station 12 and a post-welding station 13. The pre-welding station 12, the welding station 11, and the post-welding station 13 are all located on the bearing surface 41. The loading device is used to move the PCB board a at the loading station 311 to the pre-welding station 12, and the unloading device is used to move the PCB board a at the post-welding station 13 to the unloading station 312. In this way, the three operations of loading, welding, and unloading can be carried out simultaneously. The loading device moves the PCB board a to the pre-welding station 12. At the same time, soldering of the PCB board a can be carried out on the welding station 11. Meanwhile, the unloading device can move the PCB board a at the post-welding station 13 to the conveyor line 31. After welding is completed, rotating the turntable 4 can perform the next simultaneous operations of loading, welding, and unloading, thus improving the working efficiency of the soldering machine 1000.

[0039] In one embodiment, the pre-welding station 12, the welding station 11, and the post-welding station 13 are circumferentially distributed along the axis of the turntable 4. The distances from the pre-welding station 12, the welding station 11, and the post-welding station 13 to the axis of the turntable 4 are the same. Therefore, when performing the next simultaneous operations of loading, welding, and unloading after the previous welding is completed, there is no need to adjust the position of the welding equipment, which improves the working efficiency of the soldering machine 1000.

[0040] In one embodiment, the post-welding station 13, the welding station 11, and the pre-welding station 12 are arranged in sequence along the rotation direction of the turntable 4. In this way, the operation steps are simplified, and only one rotation of the turntable 4 is required to perform the next simultaneous operations of loading, welding, and unloading after the previous welding is completed, which is convenient for users.

[0041] In one embodiment, the moving assembly further includes a connecting block 2125. The lower surface of the connecting block 2125 is connected to the first longitudinal moving slider 2122, and the upper surface of the connecting block 2125 is connected to the transverse moving slide rail 2123. An inclined angle is formed between the lower surface and the upper surface of the connecting block 2125. In this way, the welding height of the welding equipment can be changed, and its application scenario can be expanded.
