The two welding wire reels 40 are respectively arranged in the first receiving space and the second receiving space, and the two welding wire reels 40 are respectively rotatably connected to the frame main body 11.

[0036] It should be noted that the receiving space includes the above-mentioned first receiving space and second receiving space.

[0037] The arrangement of the first flip cover and the second flip cover is convenient for maintaining the wire feeding mechanism on the one hand, and on the other hand, it can also prevent water and dust.

[0038] For the convenience of description, in this application, the width direction of the frame is the first direction x, the height direction is the second direction z, and the length direction is the third direction y.

[0039] In some embodiments, the first flip cover 12 is rotatably connected to the top of the frame main body 11 through a hinge assembly, so that the first flip cover 12 can rotate around the frame main body 11.

[0040] In some embodiments, such as Figure 3 shown, the rotation range of the first flip cover 12 is 0-180°. The rotation of the first flip cover 12 enables the opening of the first accommodating groove 110, facilitating the maintenance of components (such as the driver 20 or the wire feeding mechanism 30) placed inside the frame 10. It can be understood that the connection method of the second flip cover is the same as that of the first flip cover, which will not be elaborated here.

[0041] In some embodiments, such as Figure 4 and Figure 5 shown, the driver 20 includes a driving source 21 and a transmission component 22. The output end of the driving source 21 is connected to the transmission mechanism 22 to drive the transmission mechanism 22 to rotate, and the wire feeding mechanism 30 is connected to the transmission mechanism 22.

[0042] In some embodiments, the driving source 21 is a motor.

[0043] In some embodiments, the transmission component 22 includes a transmission wheel 221 and a rotating shaft 222 coaxially connected to the transmission wheel 221. The output end of the driving source 21 meshes with the transmission wheel 221 to drive the transmission wheel 221 to rotate, and the wire feeding mechanism 30 is connected to the rotating shaft 222.

[0044] In some embodiments, the wire feeding mechanism 30 includes a wire feeding assembly 31. The wire feeding assembly 31 is connected to the transmission component 22, and the two welding wire reels 40 are respectively connected to the wire feeding assembly 31 through welding wires. For example, the wire feeding assembly 31 is connected to the rotating shaft 222.

[0045] In some embodiments, the transmission mechanism 22 can adopt a worm and gear structure. The output end of the motor 21 is fixedly connected to the worm, and the transmission end of the worm is connected to the driving wheel 322 of the wire feeding mechanism 30.

[0046] In some embodiments, such as Figure 2 and Figure 6 shown, the wire feeding assembly 31 includes a housing 311, a driving wheel 312, a wire feeding wheel 313, and a rolling component. The driving wheel 312 meshes with the wire feeding wheel 313 to drive the wire feeding wheel 313 to rotate for wire feeding. The rolling component is arranged above the wire feeding wheel 313 and is used to cooperate with the wire feeding wheel 313 for wire pressing.

[0047] In some embodiments, the housing 311 of the wire feeding assembly 31 provides a stable support structure for the driving wheel 312, the wire feeding wheel 313, and the rolling component; the wire feeding wheel 313 is movably connected to the housing 311, and the rolling component is movably connected to the housing 311 and is located above the wire feeding wheel 313 along the second direction z.

[0048] In some embodiments, such as Figure 4 and Figure 6As shown, a lead-out port 3111 is provided on the housing 311 in the third direction y. An outlet pipe 32 is provided in the lead-out port 3111. The lead-out port 3111 is fixedly connected to one side of the housing 311 and is located between the wire feeding wheel 313 and the rolling assembly. The outlet pipe 32 is used to prevent the welding wire from wrinkling.

[0049] In some embodiments, grooves adapted to the welding wire are provided on the outer circumference of the wire feeding wheel 313. The rolling assembly is provided directly above the grooves. The welding wire passes through the outlet pipe 31 and enters the grooves, and is wire-pressed by the rolling assembly above.

[0050] Further, as Figure 6 shown, there are two wire feeding wheels 313, which are respectively arranged horizontally (along the third direction y) on both sides of the driving wheel 312. There are two rolling assemblies and two lead-out ports 3111. One rolling assembly cooperates with one wire feeding wheel 313. The two lead-out ports 3111 are respectively arranged on both sides of the housing 311 along the third direction y. It can be understood that the above-mentioned outlet pipes are provided in both lead-out ports.

[0051] It should be noted that the lead-out ports far from the welding wire reel are respectively connected to the first wire outlet and the second wire outlet.

[0052] In some embodiments, among the two lead-out ports, the outlet pipe in the lead-out port at the end far from the welding wire reel 40 is connected to the first wire outlet 101, so that the welding wire of the welding wire reel 40 is transported to the external welding laser head through the wire feeding assembly 31, the outlet pipe 32 and the first wire outlet 101.

[0053] After the welding wire comes out of the welding wire reel 40, it is clamped by the wire feeding wheel 313 and the rolling assembly. After the wire feeding wheel 313 rotates, it jointly rolls the welding wire with the rolling assembly. At this time, the welding wire can be continuously extruded from the outlet pipe 31 to the external laser welding head. The transportation of the two wire feeding mechanisms 30 increases the welding efficiency of the external double laser welding heads and effectively improves the use efficiency of the laser welding machine.

[0054] In some embodiments, as Figure 6As shown in the figure, the rolling component includes a wire pressing wheel mounting bracket 314, a wire pressing wheel 315, and a locking handle 316.

One end of the wire pressing wheel mounting bracket 314 is rotatably connected to the housing 311 up and down, and the other end is clamped and fixed between the locking handle 316 and the locking support end 317. The wire pressing wheel 315 is movably mounted on the wire pressing wheel mounting bracket 314. The lower end of the locking handle 316 is rotatably connected inside the locking support end 317, and a rotation avoidance groove 318 is also provided on the locking support end 317 and the wire pressing wheel mounting bracket 314. In this application, the wire pressing wheel mounting bracket 314 can rotate up and down on the housing 311 to realize the pressing and loosening of the wire pressing wheel 315. When pressing is required, rotate the wire pressing wheel mounting bracket 314 downward to make the wire pressing wheel mounting bracket 314 horizontal, and then rotate the locking handle 316 upward to clamp and lock the other end of the wire pressing wheel mounting bracket 314 between the locking handle 316 and the locking support end 317. When loosening is required, rotate the locking handle 316 downward to release the end of the wire pressing wheel mounting bracket 314, and then rotate the wire pressing wheel mounting bracket 314 upward.
