[0029] An embodiment of the present application provides a welding system, including: an alternating coaxial cyclic welding flexible circuit board device 1 and a feeding device.

[0030] As Figure 1 shown, the alternating coaxial cyclic welding flexible circuit board device 1 includes: a welding frame 10, a moving part 20, two groups of pressing head mechanisms 30, and a welding galvanometer mechanism 40.

[0031] The welding frame 10 is horizontally located on the ground. Four legs 11 are evenly distributed at the bottom of the welding frame 10. The four legs 11 are arranged at the four corners of the welding frame 10, symmetrically in pairs, to ensure the position state of the welding frame 10. On one side of the top of the welding frame 10, a first support frame 12 and a second support frame 13 perpendicular to each other are installed. The first support frame 12 is arranged on one side of the top of the welding frame 10 along the X-axis direction; the second support frame 13 is composed of two support frames, which are symmetrically arranged on both sides of the first support frame 12 respectively. The two support frames in the second support frame 13 are both perpendicular to the first support frame 12.

[0032] The moving part 20 is installed on the first support frame 12 and the second support frame 13 perpendicular to each other installed on one side of the top of the welding frame 10. The moving part 20 includes two groups of Y-axis linear modules 21 and one group of X-axis linear modules 22. The two groups of Y-axis linear modules 21 are respectively installed on the two support frames in the symmetrically arranged second support frame 13, and one group of X-axis linear modules 22 is installed on the first support frame 12.

[0033] As Figure 2 shown, both ends of one group of X-axis linear modules 22 are respectively arranged on the moving ends of the two groups of Y-axis linear modules 21. The X-axis linear module 22 is composed of two linear modules, namely a large X-axis linear module 221 and a small X-axis linear module 222. The large X-axis linear module 221 has one moving end, and the small X-axis linear module 222 has two moving ends.

[0034] The two groups of pressing head mechanisms 30 are respectively a first pressing head mechanism 31 and a second pressing head mechanism 32. The first pressing head mechanism 31 and the second pressing head mechanism 32 are respectively arranged on the two moving ends of the small X-axis linear module 222. The first pressing head mechanism 31 and the second pressing head mechanism 32 respectively move along the axis of the small X-axis linear module 222 together with the two moving ends of the small X-axis linear module 222.

[0035] The welding galvanometer mechanism 40 is arranged on the moving end of the large X-axis linear module 221. The welding galvanometer mechanism 40 moves along the axis of the large X-axis linear module 221 together with the moving end of the large X-axis linear module 221.

[0036] The feeding device is an automated guided vehicle, which is used to carry the flexible printed circuit board and move it into the internal of the alternating coaxial circular welding flexible printed circuit board device 1, transport the flexible printed circuit board below the moving part 20, and the different points in the same row of the flexible printed circuit board are in the same vertical plane as the X-axis linear module 22.

[0037] The flexible printed circuit board is carried on the automatic guided vehicle, and the flexible printed circuit board follows the automatic guided vehicle into the interior of the alternating coaxial circular welding flexible printed circuit board device 1. When the flexible printed circuit board is transported by the automatic guided vehicle to below the moving part 20, and a row of points to be welded on the flexible printed circuit board is in the same vertical plane as the X-axis linear module 22. More specifically, the small hole provided at the center of the bottom press head seat 303 is in the same vertical plane as the point to be welded. After completing the positioning and alignment work of the flexible printed circuit board and the alternating coaxial circular welding flexible printed circuit board device 1, the automatic guided vehicle and the alternating coaxial circular welding flexible printed circuit board device 1 are fixed to each other to ensure the position consistency of the flexible printed circuit board and the stability during the welding process of the equipment.

[0038] At this time, the alternating coaxial circular welding flexible printed circuit board device 1 starts to work, and the specific steps are as follows:

[0039] S1. Two sets of press head mechanisms 30 are activated. The first press head mechanism 31 presses down onto the first point on the left side of the flexible printed circuit board, and the second press head mechanism 32 presses down onto the first point on the right side of the flexible printed circuit board.

[0040] S2. The welding galvanometer mechanism 40 moves to the position in the same vertical plane as the first press head mechanism 31, and welds the first point on the left side of the flexible printed circuit board through the small hole provided at the center of the bottom press head seat 303 of the first press head mechanism 31.

[0041] S3. After the welding operation of the first point on the left side of the flexible printed circuit board at the first press head mechanism 31 is completed, the welding galvanometer mechanism 40 moves to the position in the same vertical plane as the second press head mechanism 32, and welds the first point on the right side of the flexible printed circuit board through the small hole provided at the center of the bottom press head seat 303 of the second press head mechanism 32.

[0042] Meanwhile, the first press head mechanism 31 releases the first point on the left side of the flexible printed circuit board where the welding has been completed, moves towards the middle of the flexible printed circuit board to the second point on the left side of the flexible printed circuit board, and the first press head mechanism 31 presses down onto the second point on the left side of the flexible printed circuit board.

[0043] S4. When the welding galvanometer mechanism 40 finishes welding the first point on the right side of the flexible printed circuit board, the pressing operation of the first press head mechanism 31 on the second point on the left side of the flexible printed circuit board is also completed. At this time, the welding galvanometer mechanism 40 moves to the position in the same vertical plane as the first press head mechanism 31, and welds the second point on the left side of the flexible printed circuit board through the small hole provided at the center of the bottom press head seat 303 of the first press head mechanism 31.

[0044] Meanwhile, the second pressing head mechanism 32 releases the first position on the right side of the flex circuit board that has been welded, moves towards the middle of the flex circuit board to the second position on the right side of the flex circuit board, and the second pressing head mechanism 32 presses down to the second position on the right side of the flex circuit board.

[0045] And so on, the welding galvanometer mechanism 40 moves to the place where the pressing operation has been completed for welding. Meanwhile, another pressing head mechanism performs the pressing operation. The first pressing head mechanism 31 and the second pressing head mechanism 32 are used to alternately press different positions in the same row of the flex circuit board. The welding galvanometer mechanism 40 continuously performs the welding operation back and forth between the first pressing head mechanism 31 and the second pressing head mechanism 32 in a cyclic manner.

[0046] After the alternating coaxial cyclic welding flex circuit board device 1 completes the welding of all positions in this single row of the flex circuit board, the moving ends of the two groups of Y-axis linear modules 21 drive the X-axis linear module 22 to move to other single rows of flex circuit boards that need to be welded. The alternating coaxial cyclic welding flex circuit board device 1 performs the alternating coaxial cyclic welding operation on this row of positions again. When the welding operation of all rows of positions of the flex circuit board is completed, the automatic guided transport vehicle carries the flex circuit board and drives away from the alternating coaxial cyclic welding flex circuit board device 1.

[0047] In the alternating coaxial cyclic welding flex circuit board device 1, there are two pressing head mechanisms and a welding galvanometer mechanism of the X-axis linear module. And the two pressing head mechanisms share the small X-axis. The two pressing head mechanisms alternately press different positions in the same row of the flex circuit board. When the first pressing head mechanism completes the pressing operation of a certain position of the flex circuit board and is performing welding, the second pressing head mechanism can simultaneously press different positions in the same row of the flex circuit board. When the welding at the first pressing head mechanism is completed, the welding galvanometer mechanism moves above the second pressing head mechanism to weld the position of the flex circuit board that has been pressed. While the welding galvanometer mechanism moves above the second pressing head mechanism to weld the position of the flex circuit board that has been pressed, the first pressing head mechanism presses different positions in the same row of the flex circuit board. And so on, the welding galvanometer mechanism can work back and forth alternately between the two pressing head mechanisms continuously, directly processing the positions of the flex circuit board that have been pressed, and there is no situation where the welding operation waits for the pressing operation. This welding equipment has high working efficiency.

[0048] In one embodiment, as Figure 3As shown in the figure, the indenter mechanism 30 includes an indenter base 301, an indenter downward pressing cylinder 302, and a bottom indenter seat 303. The indenter base 301 is directly arranged on the moving end of the small X-axis linear module 222. The indenter downward pressing cylinder 302 is arranged on one side of the indenter base 301 and is used to drive the bottom indenter seat 303 to press downward. A small hole is arranged at the center of the bottom indenter seat 303 for the welding galvanometer mechanism 40 to perform welding. A downward pressing pressure sensor 304 is also arranged between the indenter base 301 and the bottom indenter seat 303, and the downward pressing pressure sensor 304 monitors the pressing force of the bottom indenter seat 303. When the downward pressing pressure sensor 304 monitors that the pressing force of the bottom indenter seat 303 exceeds the specified value, the downward pressing action of the bottom indenter seat 303 is stopped to prevent damage to the workpiece caused by overpressure.

[0049] In one embodiment, the indenter mechanism 30 is further provided with an indirect distance measuring component 305. The indirect distance measuring component 305 is used to measure the height of the bottom indenter seat 303, and the height of the point position of the flexible printed circuit board is converted according to the height of the bottom indenter seat 303. The height value of the point position of the flexible printed circuit board measured by the indirect distance measuring component 305 is transmitted to the welding galvanometer mechanism 40 in real time.

[0050] In one embodiment, the indenter mechanism 30 further includes a welding dust extraction mechanism 306. The welding dust extraction mechanism 306 is arranged on one side of the bottom indenter seat 303 and is used to collect the dust generated during the welding process.

[0051] In one embodiment, as Figure 4 shown in the figure, the welding galvanometer mechanism 40 includes a vertical seat plate 401, a Z-axis linear module 402, and a welding galvanometer kit 403. The vertical seat plate 401 is directly arranged on the moving end of the large X-axis linear module 221. The Z-axis linear module 402 is installed on one side of the vertical seat plate 401. The welding galvanometer kit 403 is arranged on the moving end of the Z-axis linear module 402, and the welding galvanometer kit 403 and the moving end of the Z-axis linear module 402 move along the axial direction of the Z-axis linear module 402. According to the data obtained by the indirect distance measuring component 305, the welding galvanometer kit 403 moves along the axial direction of the Z-axis linear module 402 to adjust the height of the welding galvanometer kit 40 in the welding galvanometer mechanism 40 in real time, ensuring that the height of the welding galvanometer kit 403 is the same as that of each point position of the flexible printed circuit board. Ensure that the welding focus is the same for each point position of the flexible printed circuit board. The laser outlet of the welding galvanometer kit 403 and the small hole at the center of the bottom indenter seat 303 are located in the same vertical plane.

[0052] In one embodiment, the welding galvanometer mechanism 40 further includes a vision positioning component 404. The vision positioning component 404 is disposed on one side of the welding galvanometer kit 403. When the welding galvanometer mechanism 40 moves near a pressing head mechanism 30 after the pressing operation is completed, the vision positioning component 404 captures the position of the flexible printed circuit board after being pressed by the pressing head mechanism 30. The vision positioning component 404 obtains the position information of the flexible printed circuit board after being pressed by the pressing head mechanism 30. According to the position information, it is indicated that the welding galvanometer kit 403 does not need to move again, and directly performs offset welding on the position of the flexible printed circuit board after being pressed by the pressing head mechanism 30.

[0053] In one embodiment, the feeding device further includes an automatic guided vehicle positioning component, which is used to indicate the travel of the automatic guided vehicle and fix the automatic guided vehicle carrying the flexible printed circuit board so that it does not move under the alternating coaxial cyclic welding flexible printed circuit board device.

[0054] As described above, the above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application.
