[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0019] See Figures 1 to 13 As shown, this invention discloses an embodiment of a bending and welding device.

[0020] The material to be bent and welded 1 includes a housing 11 and a ribbon cable 12. The housing 11 has a first end and a second end facing away from each other. The first end of the housing 11 is provided with a first metal sheet 13. The ribbon cable 12 has a first edge and a second edge that are parallel to each other. The first edge of the ribbon cable 12 is connected to the first end of the housing 11. The second edge of the ribbon cable 12 is provided with a second metal sheet 14. When the ribbon cable 12 is in a bent state, the second metal sheet 14 overlaps the first metal sheet 13.

[0021] In the above description, the housing 11 is a rigid support component with a first end and a second end facing away from each other. The first end connects to the ribbon cable 12 and supports the first metal sheet 13, serving to fix and support the ribbon cable and ensure the overall structural stability. The ribbon cable 12 is typically a flexible flat cable (FFC), a flexible and bendable connector with parallel first and second edges, used to connect the housing 11 and fix the second metal sheet 14, respectively. After bending, the second metal sheet 14 can overlap with the first metal sheet 13. The first metal sheet 13 serves as a welding reference; its flat surface allows it to overlap with the second metal sheet 14 for welding, achieving electrical conductivity or structural fixation. The second metal sheet 14 is adapted to the first metal sheet 13. When the ribbon cable 12 is bent to a preset shape, the second metal sheet 14 can precisely overlap the first metal sheet 13, serving as the component to be connected in the welding process.

[0022] The aforementioned bending and welding equipment includes: The positioning device 2 has a wiring station on one side along the horizontal X-axis, which is used to fix the position of the housing 11 and place the wiring 12 in the wiring station. The bending device 3 is used to apply downward pressure to a portion of the cable 12 above the cable 12 at the above-mentioned cable 12 station. The side-pushing device 4 is used to apply a lateral thrust toward the housing to the outer side of the portion of the cable 12 near the second edge at the cable laying station. Support device 5 is used to abut against the inner side of the portion of the cable 12 near the second edge between the first metal sheet 13 and the portion of the cable 12 near the first edge at the above-mentioned cable laying station, and to support the first metal sheet 13. The pressure holding device 6 is used to press the second metal sheet 14 above the first metal sheet 13 at the above-mentioned wiring station and expose the welding position of the second metal sheet 14. The laser welding device 7 is used to weld the position of the second metal sheet 14 to be welded above the first metal sheet 13 at the above-mentioned wiring station. A first visual inspection device (not shown in the figure) is used to detect the position of the second metal sheet 14 above the first metal sheet 13 at the above-mentioned wiring station; The second visual inspection device 8 is used to detect the gap between the first metal sheet 13 and the second metal sheet 14 from the side of the first metal sheet 13 at the above-mentioned wiring station. The laser ranging device 9 is used to detect the distance between the first metal sheet 13 and the upper surface of the second metal sheet 14 above the above-mentioned wiring station.

[0023] In the above text, the positioning device 2 is used for reference positioning. One side along the horizontal X-axis is designated as the wiring station. Its core function is to fix the position of the housing 11 and accurately guide the wiring 12 to the wiring station, providing a stable positioning reference for subsequent bending, alignment and welding processes.

[0024] The bending device 3, the side pushing device 4, and the support device 5 work together to perform the bending action. During operation, the support device 5 serves as a positioning reference for the inner side of the portion of the cable 12 near the second edge after bending. The bending device 3 applies downward pressure from above the cable 12 in the cable laying station, forcing the cable 12 to undergo plastic deformation. At the same time, the side pushing device 4 applies a lateral pushing force towards the housing 11 on the outer side of the second edge of the cable 12 in the cable laying station, forming a preset bending shape to ensure that the second metal sheet 14 can be accurately aligned with the first metal sheet 13.

[0025] The support device 5 and the pressure holding device 6 work together to perform the pressure holding action. The support device 5 provides an upward support force at the bottom of the first metal sheet 13 in the wiring station, and the pressure holding device 6 provides a downward pressure at the top of the second metal sheet 14 in the wiring station, clamping the first metal sheet 13 and the second metal sheet 14 together to ensure a tight connection between them. At the same time, the pressure holding device 6 avoids the welding position of the second metal sheet 14 and does not interfere with the subsequent laser welding operation.

[0026] The laser welding device 7 is used to perform welding operations. It emits a laser at the welding position of the second metal sheet 14 in the wiring station and uses the high energy of the laser to achieve the fusion of the first metal sheet 13 and the second metal sheet 14.

[0027] The first vision inspection device is used to detect the positional accuracy of the second metal sheet 14. It acquires a positional image of the second metal sheet 14 above the first metal sheet 13 in the wiring station, and judges the alignment deviation of the second metal sheet 14 through image analysis, providing data basis for subsequent compensation and adjustment.

[0028] The second visual inspection device 8 is used to detect the size of the gap between the first metal sheet 13 and the second metal sheet 14. It collects a gap image of the overlap between the first metal sheet 13 and the second metal sheet 14 from the side of the first metal sheet 13 in the wiring station, detects the size of the gap between the first metal sheet 13 and the second metal sheet 14, and determines whether the welding process requirements are met.

[0029] The laser ranging device 9 is used to detect the flatness of the upper surface of the second metal sheet 14. It emits a laser beam above the first metal sheet 13 in the wiring station to determine whether each position of the second metal sheet 14 is tightly attached to the first metal sheet 13.

[0030] Specifically, the bending and welding method of the aforementioned bending and welding equipment includes the following steps: S1. The housing 11 is positioned by the positioning device 2 and the cable 12 is placed at the cable laying position, with the cable 12 in a flat state. S2. The first visual inspection device detects the position of the second metal sheet 14 in real time above the first metal sheet 13 at the wiring station. The second visual inspection device 8 detects the gap between the second metal sheet 14 and the first metal sheet 13 in real time from the side of the first metal sheet 13 and the second metal sheet 14. The support device 5 is located between the first metal sheet 13 and the portion of the wiring 12 near the first edge. The bending device 3 applies downward pressure to the wiring 12 from above. At the same time, the side pushing device 4 applies a side pushing force towards the housing 11 to the wiring 12 from the outside of the second edge of the wiring 12 until the second metal sheet 14 is located at a preset position above the first metal sheet 13 and the gap between it and the first metal sheet 13 is a preset size. S3. The aforementioned support device 5 is supported below the first metal sheet 13; S4. The aforementioned pressure-holding device 6 presses against the top of the second metal sheet 14; S5. The laser ranging device 9 detects whether the distance between itself and different positions of the second metal sheet 14 is the same. If yes, proceed to step S6. If no, recycle the material to be bent and welded. S6. The laser welding device 7 described above welds the second metal sheet 14 and the first metal sheet 13.

[0031] Step S1 is the initial stage of the process, ensuring that the shell 11 is free from displacement to avoid errors in subsequent bending and alignment due to reference offset.

[0032] Step S2 is the core step in resolving the mutual interference between bending and alignment. It adopts a closed-loop control mode of detection-action-correction: the first visual detection device collects the position data of the second metal sheet 14 from above in real time and judges its horizontal alignment deviation with the first metal sheet 13; the second visual detection device 8 detects the gap between the two metal sheets from the side in real time and judges whether it meets the welding gap requirements; the support device 5 serves as the inner side reference for the cable bending, the bending device 3 applies downward pressure to cause the cable 12 to undergo plastic deformation, and the side pushing device 4 simultaneously applies a lateral pushing force towards the housing 11. The support device 5, bending device 3 and side pushing device 4 dynamically adjust the action amplitude according to the visual detection data, and finally push the second metal sheet 14 precisely above the first metal sheet 13, and the position and gap meet the preset standards.

[0033] Step S3 prevents the metal sheet from deforming due to pressure or laser thermal effect during subsequent pressure holding and welding processes, ensuring the flatness of the welding reference surface.

[0034] Step S4 can eliminate the microscopic gap between the first metal sheet 13 and the second metal sheet 14, improve welding reliability, and fix the position of the second metal sheet 14 to prevent displacement before welding.

[0035] Step S5 is a quality screening step before welding. If the distances at each position are the same, it means that the upper surface of the second metal sheet 14 is flat and the first metal sheet 13 and the second metal sheet 14 are evenly bonded, meeting the welding conditions. If the distances are different, it means that the first metal sheet 13 or the second metal sheet 14 has problems such as warping or poor bonding. Such materials need to be recycled to avoid flowing into the welding process and causing defective products.

[0036] Step S6 is the final step of the process. The laser welding device 7 emits a laser at the welding position of the second metal sheet 14. The high energy density of the laser melts and fuses the contact area of ​​the two metal sheets. After cooling, a strong welded joint is formed.

[0037] The bending and welding equipment, as described above, includes a positioning device, a bending device, a side-pushing device, a supporting device, and a pressure-holding device. When bending the cable, the positions of the first and second metal sheets can be adjusted to achieve precise alignment of the cable bending and the metal sheets.

[0038] In this embodiment, the positioning device 2 includes a bearing mechanism 21, a clamping mechanism 22, an abutting mechanism 23, and a rotary drive 24. The bearing mechanism 21 is used to support the bottom of the housing 11. The clamping mechanism 22 is used to clamp the two sides of the housing 11 along the horizontal Z-axis. The abutting mechanism 23 is used to abut the second end of the housing 11. The rotary drive 24 connects the bearing mechanism 21, the clamping mechanism 22, and the abutting mechanism 23, and is used to drive the bearing mechanism 21, the clamping mechanism 22, and the abutting mechanism 23 to rotate synchronously around the vertical Y-axis.

[0039] In the above description, the bearing mechanism 21 provides bottom support, offering a stable vertical support reference for the housing 11 and preventing it from sinking, tilting, or shifting during bending, alignment, and welding processes. The clamping mechanism 22 provides lateral positioning, ensuring precise positioning and clamping of the housing 11 along the horizontal Z-axis, preventing lateral displacement due to pressure or thrust from subsequent devices. The abutment mechanism 23 provides lateral limiting, restricting the displacement of the housing 11 along its length. Working in conjunction with the bearing mechanism 21 and clamping mechanism 22, it fixes the housing 11 in three-dimensional space, ensuring that the first end of the housing 11 (the cable connection end) is always in the preset position of the cable routing station. The rotary drive component 24 is a power-driven component connected to the bearing mechanism 21, clamping mechanism 22, and abutment mechanism 23. It drives these three mechanisms to rotate synchronously around the vertical Y-axis, adjusting the attitude angle of the housing and cable to adapt to bending and welding requirements at different angles, thus improving the equipment's process compatibility.

[0040] Specifically, the shell 11 of the material to be bent and welded is placed in a preset position on the supporting mechanism 21, and the clamping mechanism 22 and the abutting mechanism 23 move synchronously to position the shell 11. When it is necessary to adjust the angle of the material to be bent and welded, the supporting mechanism 21, the clamping mechanism 22, and the abutting mechanism 23 are driven to rotate synchronously by the rotating drive component 24.

[0041] The positioning device, which includes a bearing mechanism, a clamping mechanism, an abutment mechanism, and a rotating drive component, provides a high-precision and high-stability material reference for subsequent bending, alignment, and welding processes through multi-dimensional collaborative positioning and adjustable posture design.

[0042] In this embodiment, the bending device 3 includes a bending rod 31, a first Z-axis drive 32, a first Y-axis drive 33, and a first X-axis drive 34. The bending rod 31 extends along the horizontal Z-axis direction and is used to directly contact the ribbon cable 12. The first Z-axis drive 32 is connected to the bending rod 31 and is used to drive the bending rod 31 to move along the horizontal Z-axis. The first Y-axis drive 33 is connected to the first Z-axis drive 32 and is used to drive the first Z-axis drive 32 to move along the vertical Y-axis direction. The first X-axis drive 34 is connected to the first Y-axis drive 33 and is used to drive the first Y-axis drive 33 to move along the horizontal X-axis direction.

[0043] In the above description, the bending rod 31 is a cylindrical or flat rigid rod used to directly contact the cabling 12 and apply pressure, forcing the cabling to undergo plastic deformation to form a preset bending shape. The first Z-axis drive 32, the first Y-axis drive 33, and the first X-axis drive 34 are all power components that realize the spatial movement of the bending rod 31. The first Z-axis drive 32 is used to drive the bending rod 31 to extend to or away from the cabling station. The contact position between the bending rod and the cabling can be adjusted to adapt to the bending requirements of cablings with different widths, while also achieving precise alignment of the bending rod. The first Y-axis drive 33 is used to drive the bending rod to apply downward pressure to the cabling, providing the downward pressure required for bending the cabling, while also controlling the bending depth and pressure. The first X-axis drive 34 can adjust the position of the bending rod 31 in the horizontal X-axis direction, precisely positioning the bending area of ​​the cabling 12.

[0044] Specifically, before bending the cable, the bending rod 31 is in its initial position. During bending, firstly, the first Z-axis drive 32 moves the bending rod 31 along the horizontal Z-axis, positioning it above the cable 12. Then, the first X-axis drive 34 adjusts the bending rod 31 to precisely position it above the preset bending area of ​​the cable 12. Finally, the first Y-axis drive 33 moves the bending rod 31 downwards to bend the cable 12. After bending, the bending rod 31 returns to its initial position.

[0045] Through the above technical solution, the position of the bending bar can be precisely controlled by the X, Y, and Z three-axis drive components. This can accurately locate the bending area of ​​the cable and precisely control the bending depth and pressure, avoiding cable damage or substandard bending angle caused by bending position deviation or excessive pressure, thus ensuring bending consistency.

[0046] In this embodiment, the side-pushing device 4 includes a side-pushing plate 41, a second Y-axis drive 42, a second X-axis drive 43, and a second Z-axis drive 44. The side-pushing plate 41 is perpendicular to the horizontal X-axis direction and is used to directly contact the ribbon cable 12. The second Y-axis drive 42 is connected to the side-pushing plate 41 and is used to drive the side-pushing plate 41 to move along the vertical Y-axis direction. The second X-axis drive 43 is connected to the second Y-axis drive 42 and is used to drive the second Y-axis drive 42 to move along the horizontal X-axis direction. The second Z-axis drive 44 is connected to the second X-axis drive 43 and is used to drive the second X-axis drive 43 to move along the horizontal Z-axis direction.

[0047] In the above description, the side push plate 41 is made of rigid material and is used to directly contact the second edge of the ribbon cable 12, applying a stable lateral thrust to avoid deformation of the ribbon cable or displacement of the metal sheet due to single-point force. The second Y-axis drive component 42 can adjust the height of the side push plate 41 to precisely match the height of the second edge of the ribbon cable 12, ensuring the rationality of the thrust application point. The thrust and displacement of the second X-axis drive component 43 can be precisely controlled, and it is the core power source for pushing the ribbon cable 12 to bring the second metal sheet 14 closer to the first metal sheet 13. The second Z-axis drive component 44 can adjust the horizontal lateral position of the side push plate 41 to adapt to ribbon cables of different widths, ensuring that the side push plate 41 fully fits the edge of the ribbon cable 12.

[0048] Specifically, before the cable is bent, the side push plate 41 is in its initial position. During the bending process, firstly, the second Y-axis drive 42 and the second Z-axis drive 44 cooperate to adjust the position of the side push plate 41 so that it aligns with the cable 12. Then, the second X-axis drive 43 moves the side push plate 41 closer to the housing to bend the cable. After the cable is bent, the side push plate 41 returns to its initial position.

[0049] Through the above technical solution, the height and horizontal lateral position of the side push plate can be precisely adjusted by the Y-axis and Z-axis drive components, and the thrust and displacement can be precisely controlled by the X-axis drive component. The parameters can be dynamically adjusted according to the cable specifications and alignment requirements to avoid cable damage due to excessive thrust or alignment deviation due to insufficient thrust.

[0050] In this embodiment, the support device 5 includes a support bar 51, a third Y-axis drive member 52, a third Z-axis drive member 53, and a third X-axis drive member 54. The support bar 51 extends along the horizontal Z-axis direction and is used to directly contact the first metal sheet 13. The third Y-axis drive member 52 is connected to the support bar 51 and is used to drive the support bar 51 to move along the vertical Y-axis direction. The third Z-axis drive member 53 is connected to the third Y-axis drive member 52 and is used to drive the third Y-axis drive member 52 to move along the vertical Y-axis direction. The third X-axis drive member 54 is connected to the third Z-axis drive member 53 and is used to drive the third Z-axis drive member 53 to move along the horizontal X-axis direction.

[0051] In the above description, the support bar 51 is made of rigid material and has a flat support surface. It is used to support the bottom of the first metal sheet 13, preventing the metal sheet from deforming due to pressure or laser heat effect during welding, thus ensuring the stability of the welding reference surface. The third Y-axis drive 52 is the core power source for raising and lowering the support bar 51, and can precisely control the contact pressure between the support bar and the first metal sheet 13. The third Z-axis drive 53 is used to move the support bar 51 to or away from the wiring station. The third X-axis drive 54 can adjust the support position of the support bar 51 so that it is precisely aligned with the area of ​​the first metal sheet 13 to be supported.

[0052] Specifically, before the cable is bent, the support bar 51 is in its initial position. During the bending process, the third Y-axis drive 52, the third Z-axis drive 53, and the third X-axis drive 54 are activated, causing the support bar 51 to move along the vertical Y-axis, horizontal Z-axis, and horizontal X-axis directions. This positions the support bar 51 at a preset position between the first metal sheet 13 and the portion of the cable 12 near its first edge, preparing it to abut against the inner side of the portion of the cable 12 near its second edge. After the cable is bent, the third X-axis drive 54 is activated, adjusting the support bar 51 so that it supports the area directly below the preset support region of the first metal sheet 13. After welding, the support bar 51 returns to its initial position.

[0053] Through the above technical solution, the X, Y, and Z axis positions of the support bar can be precisely adjusted, which can realize the positioning of the cable bending and the precise alignment with the first metal sheet, ensuring that the support force is applied to the effective area of ​​the metal sheet, avoiding local deformation of the metal sheet due to the deviation of the support position, and ensuring the flatness of the welding surface.

[0054] In this embodiment, the pressure holding device 6 includes a pressure claw 61, a fourth Y-axis drive 62, a fourth X-axis drive 63, and a fourth Z-axis drive 64. The pressure claw 61 is used to directly contact the second metal sheet 14. The fourth Y-axis drive 62 is connected to the pressure claw 61 and is used to drive the pressure claw 61 to move along the vertical Y-axis direction. The fourth X-axis drive 63 is connected to the fourth Y-axis drive 62 and is used to drive the fourth Y-axis drive 62 to move along the horizontal X-axis direction. The fourth Z-axis drive 64 is connected to the fourth X-axis drive 63 and is used to drive the fourth X-axis drive 63 to move along the horizontal Z-axis direction.

[0055] In the above description, the clamping jaw 61 is made of a rigid material to ensure a tight fit between the second metal sheet 14 and the first metal sheet 13. Simultaneously, the structural design of the clamping jaw 61 must avoid the welding area of ​​the second metal sheet 14 to prevent interference with the laser welding operation. The fourth Y-axis drive 62 performs the clamping and releasing actions of the clamping jaw 61 and precisely controls the holding pressure. The fourth X-axis drive 63 adjusts the position of the clamping jaw 61 in the horizontal X-axis direction, and the fourth Z-axis drive 64 adjusts the position of the clamping jaw 61 in the horizontal Z-axis direction, ensuring precise alignment with the non-welding area of ​​the second metal sheet 14.

[0056] Specifically, before the metal sheet is held under pressure, the clamping claw 61 is in its initial position. During the holding pressure process, firstly, the fourth X-axis drive 63 and the fourth Z-axis drive 64 actuate, moving the clamping claw 61 above the second metal sheet 14 and adjusting its position. Then, the fourth Y-axis drive 62 actuates, moving the clamping claw 61 downward to press the second metal sheet 14 firmly. After welding, the clamping claw 61 returns to its initial position.

[0057] Through the above technical solution, the X, Y, and Z axis positions of the pressure claw can be independently and precisely controlled, which can not only accurately avoid the area to be welded, but also make the pressure evenly applied to the effective area of ​​the second metal sheet, avoiding metal sheet deformation or welding interference caused by pressure claw position deviation.

[0058] In this embodiment, the laser welding device 7 includes a laser welding head 71 and a fifth Y-axis drive member 72. The laser welding head 71 is used to perform laser welding, and the fifth Y-axis drive member 72 drives the laser welding head 71 to move along the vertical Y-axis direction.

[0059] In the above description, the laser welding head 71 incorporates a laser generator, focusing lens, and other components to generate and output a high-energy-density laser beam, which is focused on the overlapping area of ​​the second metal sheet 14 and the first metal sheet 13, causing the metal in the contact area to melt and fuse instantly. The fifth Y-axis drive unit 72 adjusts the vertical distance between the laser welding head and the area to be welded, achieving precise focusing of the laser focal point and ensuring effective transfer of welding energy.

[0060] Specifically, before welding, the laser welding head 71 is in its initial position. During laser welding, firstly, the fifth Y-axis drive component 72 is activated, moving the laser welding head 71 downwards along the vertical Y-axis to adjust the height of the welding head to a preset value, ensuring that the laser focus is precisely placed at the interface between the two metal sheets, thus concentrating the welding energy on the welding area. Then, the laser welding head 71 is activated, outputting a laser beam with a preset power and pulse width to scan or perform spot welding on the position to be welded on the second metal sheet 14. During the welding process, the pressure holding device maintains pressure continuously, and the support device provides continuous support to prevent the metal sheets from shifting due to thermal deformation, ensuring the quality of the weld formation. After welding is completed, the laser welding head 71 returns to its initial position.

[0061] The above technical solution achieves focus height adjustment only through the fifth Y-axis drive component, simplifying the structure and reducing the complexity of equipment debugging and control.

[0062] In this embodiment, the second vision detection device is integrated into the laser welding head 71.

[0063] In the above text, the laser welding head 71 serves as an integrated carrier. While retaining the laser emission and focusing functions, it also reserves installation space for the second vision inspection device to ensure that the inspection optical path and the laser welding optical path do not interfere with each other. At the same time, the position adjustment of the laser welding head can synchronously drive the second vision inspection device to move, achieving precise matching between the inspection position and the welding position.

[0064] Specifically, the laser welding head 71 is located above the cable tray station. When performing laser welding, it is necessary to detect the position of the second metal sheet 14. The same second vision detection device is used to detect the position of the second metal sheet 14 during alignment and welding.

[0065] By using the above technical solution, the independent installation station for the second vision inspection device is eliminated, and it is integrated into the laser welding head, reducing the overall space occupied by the equipment, simplifying the equipment layout, and lowering the production line construction cost.

[0066] In this embodiment, the laser ranging device 9 includes a laser head 91, a fifth Z-axis drive 92, and a fifth X-axis drive 93. The laser head 91 is used for laser ranging. The fifth Z-axis drive 92 is connected to the laser head 91 and is used to drive the laser head 91 to move along the horizontal Z-axis direction. The fifth X-axis drive 93 is connected to the fifth Z-axis drive 92 and is used to drive the fifth Z-axis drive 92 to move along the horizontal X-axis direction.

[0067] In the above description, the laser head 91 calculates the vertical distance to the upper surface of the second metal sheet 14 by emitting a laser beam and receiving reflected signals. This distance is used to determine the surface flatness of the second metal sheet 14 and ensure that the welding process requirements are met. The laser head 91 scans the second metal sheet 14 along the horizontal X-axis direction. The fifth Z-axis drive unit 92 is used to adjust the position of the laser head 91 in the horizontal Z-axis direction, and the fifth X-axis drive unit 93 is used to adjust the position of the laser head 91 in the horizontal X-axis direction.

[0068] Specifically, the bending and welding equipment includes two bending alignment units A arranged along the horizontal X-axis. Each bending alignment unit A includes a positioning device 2, a bending device 3, a side pushing device 4, a supporting device 5, and a pressure holding device 6. Each of the two bending alignment units A is equipped with a laser welding device 7 and a second vision inspection device 8, and they share a laser ranging device 9. The laser head 91 is driven to move between the two bending alignment units A through the fifth X-axis driving component.

[0069] The above technical solution uses X and Z dual-axis drive components to move the laser head, thereby achieving laser head position adjustment and switching between two bending alignment units.

[0070] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
