Description

Technical Field

[0001] This invention relates to the field of metal welding, specifically to an electric welding device for manufacturing photovoltaic equipment components. Background Technology

[0002] Photovoltaic equipment components, such as photovoltaic brackets, mounting frames, and frames, require welding during the manufacturing process.

[0003] In current photovoltaic equipment component welding operations, workpiece leveling largely relies on manual adjustments using shims and pads. Leveling accuracy is highly dependent on operator experience, the adjustment process is time-consuming, and the shims are prone to displacement during welding, affecting dimensional consistency. Workpiece clamping often employs bolt plates or rigid fixtures, making clamping force difficult to control. Rigid compression can easily cause localized deformation of thin-walled components, and changing workpieces of different sizes requires readjusting the fixture positions, resulting in low adaptation efficiency.

[0004] For large photovoltaic components requiring double-sided welding, the flipping operation typically relies on manual handling or lifting equipment, which is labor-intensive, poses safety hazards, and requires re-clamping and repositioning after flipping. Repeated positioning errors can affect weld alignment accuracy, reducing welding quality and production efficiency. Existing welding fixtures mostly have only a single clamping function, and processes such as leveling, clamping, and flipping require multiple sets of equipment or multiple clamping operations, making the process cumbersome and difficult to meet the continuous operation requirements for batch welding of large photovoltaic components.

[0005] Therefore, there is a need to provide an electric welding device for manufacturing photovoltaic equipment components, which aims to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an electric welding device for manufacturing photovoltaic equipment components.

The flipping assembly includes a movable base, which is slidably connected to the top of the welding workbench. A rectangular limiting plate is slidably connected to the top of the movable base, a room-shaped trigger block is fixedly connected to the bottom of the rectangular limiting plate, and a hydraulic rod is fixedly connected to the bottom of the movable base. The fixing component includes a positioning groove plate, which is disposed above the welding workbench. A strip-shaped slider is symmetrically slidably connected inside the positioning groove plate, and several limiting clamping blocks are symmetrically slidably connected inside the two strip-shaped sliders.

[0008] Preferably, the tilting assembly includes a lifting seat, which is fixedly connected to the output shaft of the hydraulic rod, and limit rods are symmetrically fixedly connected to the outer wall of the lifting seat.

[0009] Preferably, the flipping assembly includes a rotating rod rotatably connected inside the lifting seat. Both limiting rods are arranged on the movement path of the rotating rod. A first return spring is hinged to the bottom of the rotating rod. The end of the first return spring away from the rotating rod is hinged to the lifting seat. A triangular rotating block is fixedly connected to the end of the rotating rod away from the first return spring. The end of the triangular rotating block away from the rotating rod is fixedly connected to the positioning groove plate.

[0010] Preferably, the fixing assembly includes a cover plate assembly that is snapped onto the outer wall of the positioning groove plate. Each of the limiting clamping blocks is fixedly connected to a second return spring at one end near the strip slider, and the end of the second return spring away from the limiting clamping block is fixedly connected to the strip slider.

[0011] Preferably, the fixing component includes a limiting slider, which is fixedly connected to the bottom of the strip slider, and a bidirectional threaded rod is rotatably connected to the bottom of the positioning groove plate, and a rotating handle is fixedly connected to the outer wall of the bidirectional threaded rod.

[0012] Preferably, the leveling and adjusting assembly includes two sets of positioning toothed plates, which are respectively fixedly connected to two sets of cover plates. Each set of positioning toothed plates is slidably connected to a rectangular slider, and each rectangular slider is slidably connected to a J-shaped pressing block assembly.

[0013] Preferably, the leveling and adjusting assembly includes four positioning blocks, with each pair of positioning blocks forming a group. The two groups of positioning blocks are respectively fixedly connected to the inner wall of the rectangular slider. Each rectangular slider is provided with a third return spring inside. The two ends of the third return spring are respectively fixedly connected to the J-shaped pressing block group and the positioning block. A leveling and adjusting plate is fixedly connected between the two rectangular sliders.

[0014] Preferably, both the rectangular limiting plate and the room-shaped trigger block are positioned on the movement path of the triangular rotating block.

[0015] Preferably, several of the limiting clamping blocks are slidably connected inside the cover plate assembly, and the bidirectional threaded rod is threadedly connected inside the limiting slider.

[0016] Preferably, the leveling and adjusting plate is positioned below the limiting clamping block.

[0017] The welding device for manufacturing photovoltaic equipment components provided by this invention has the following advantages compared with the prior art: This solution is designed for double-sided welding of large-size photovoltaic equipment components. It integrates automatic leveling, bidirectional centering clamping, and mechanical flipping. The workpiece can complete the entire process of leveling, clamping, and flipping in one clamping. After flipping, the workpiece still maintains its original centering clamping state, eliminating the need for re-clamping and positioning, avoiding repeated positioning errors, ensuring the alignment accuracy of welds in double-sided welding, reducing auxiliary time for multi-process connections, and improving the efficiency of continuous welding operations.

[0018] This solution can automatically flip the triangular rotating block and the positioning groove plate 180 degrees with a single extension and retraction cycle of the hydraulic rod, realizing automatic workpiece flipping without the need for manual handling or lifting equipment, thus reducing the labor intensity and safety risks of flipping large-sized components. The flipping action is automatically triggered and reset by mechanical linkage, making it easy to operate and suitable for the continuous flipping needs in mass production.

[0019] This solution features a leveling and adjusting plate and a two-way centering clamping structure. After the workpiece is placed, it automatically conforms to the flat support surface under its own weight, achieving automatic leveling without the need for repeated manual leveling and correction. The two-way threaded rod drives the two-sided limiting clamping blocks to move synchronously in center. With the elastic compensation of the second return spring, it can ensure effective clamping preload while avoiding surface damage and deformation caused by rigid extrusion. At the same time, the threaded drive has a self-locking characteristic, which can prevent the clamping from loosening due to vibration and thermal deformation during welding, ensuring the stability of welding positioning.

[0020] This solution features a press-to-unlock height adjustment structure. Pressing both sides of the pressing block group simultaneously releases the toothed locking mechanism, causing the rectangular slider and leveling plate to rise and fall vertically along the positioning toothed plate group. Once adjusted to the correct position, releasing the slider will automatically engage the toothed locking mechanism. This design allows for quick adaptation to photovoltaic equipment components of different heights and sizes, expanding the applicability of the device.

[0021] The movable seats on both sides of this solution can move horizontally along the top of the welding workbench to adjust the spacing between the flipping components on both sides, adapting to photovoltaic equipment components of different lengths and specifications, and further improving the device's adaptability to workpieces of multiple specifications.

[0022] The entire system is based on a purely mechanical linkage structure, ensuring stable and reliable positioning. It is suitable for the high-temperature, dusty, and high-vibration working environment of welding workshops, and its maintenance is simple and its operating cost is low. It can meet the long-term use needs of mass welding production of photovoltaic equipment components. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a welding device for manufacturing photovoltaic equipment components, including a welding workbench 11, a control console 12 and a welding gun 13. The control console 12 and the welding gun 13 are both disposed on the top of the welding workbench 11. A flipping component is symmetrically disposed on the top of the welding workbench 11. A fixing component is disposed above the welding workbench 11. A leveling and adjusting component is disposed on the fixing component.

[0029] like Figure 3 and Figure 4 As shown, the movable base 21 is slidably connected to the top of the welding workbench 11. The movable base 21 is controlled to move horizontally by the control console 12. This is prior art and will not be described in detail here. A rectangular limiting plate 22 is slidably connected to the top of the movable base 21. A room-shaped trigger block 23 is fixedly connected to the bottom of the rectangular limiting plate 22. A hydraulic rod 24 is fixedly connected to the bottom of the movable base 21. The hydraulic rod 24 is controlled to lift and lower by the control console 12.

[0030] The lifting seat 25 is fixedly connected to the output shaft of the hydraulic rod 24, and limit rods 26 are symmetrically fixedly connected to the outer wall of the lifting seat 25. The rotating rod 27 is rotatably connected inside the lifting seat 25, and both limit rods 26 are set on the movement path of the rotating rod 27 to limit the extreme position of the rotating rod 27 after it has rotated 180 degrees. One end of the first return spring 28 is hinged to the bottom of the rotating rod 27, and the other end is hinged to the lifting seat 25. A triangular rotating block 29 is fixedly connected to the end of the rotating rod 27 away from the first return spring 28.

[0031] Both the rectangular limiting plate 22 and the chamber-shaped trigger block 23 are positioned on the movement path of the triangular rotating block 29. When the triangular rotating block 29 rises, it abuts against the rectangular limiting plate 22, triggering a flip. When it falls, it abuts against the chamber-shaped trigger block 23, causing the rectangular limiting plate 22 to slide and reset, preparing for the next flip. The two ends of the positioning groove plate 31 are fixedly connected to the triangular rotating blocks 29 on both sides. When the triangular rotating block 29 flips, it causes the positioning groove plate 31 and the clamped workpiece to flip as a whole.

[0032] like Figure 8 and Figure 9 As shown, a positioning groove plate 31 is positioned above the welding workbench 11. A strip-shaped slider 33 is symmetrically slidably connected inside the positioning groove plate 31. Several limiting clamping blocks 34 are symmetrically slidably connected inside the two strip-shaped sliders 33. A cover plate assembly 32 is snapped onto the outer wall of the positioning groove plate 31, and several limiting clamping blocks 34 are slidably connected inside the cover plate assembly 32. A second return spring 35 is fixedly connected to one end of each limiting clamping block 34 near the strip-shaped slider 33. The other end of the second return spring 35, away from the limiting clamping block 34, is fixedly connected to the strip-shaped slider 33. The second return spring 35 provides elastic compensation for clamping, preventing rigid compression damage to the workpiece.

[0033] The limiting slider 36 is fixedly connected to the bottom of the strip slider 33. A bidirectional threaded rod 37 is rotatably connected to the bottom of the positioning groove plate 31. A rotating handle 38 is fixedly connected to the outer wall of the bidirectional threaded rod 37. The bidirectional threaded rod 37 is threadedly connected to the inside of the limiting slider 36. Rotating the rotating handle 38 drives the bidirectional threaded rod 37 to rotate, which drives the limiting sliders 36 on both sides to move synchronously in the center or in the opposite direction, realizing the centering and clamping of the workpiece.

[0034] like Figures 5 to 7 As shown, two sets of positioning toothed plate assemblies 41 are fixedly connected to two sets of cover plate assemblies 32, respectively. A rectangular slider 42 is slidably connected to each set of positioning toothed plate assemblies 41, and a J-shaped pressing block assembly 44 is slidably connected inside each rectangular slider 42. Four positioning blocks 43 are arranged in pairs, and the two sets of positioning blocks 43 are fixedly connected to the inner wall of the rectangular slider 42. A third return spring 45 is fixedly connected between each set of J-shaped pressing block assemblies 44 and the positioning block 43.

[0035] A protrusion is provided at one end of the J-shaped pressing block assembly 44 near the positioning toothed plate assembly 41. Correspondingly, a toothed groove is provided on the inner wall of the positioning toothed plate assembly 41. When the protrusion is engaged in the toothed groove, the rectangular slider 42 is locked and cannot slide. Pressing the J-shaped pressing block assembly 44 disengages the protrusion from the toothed groove, allowing the rectangular slider 42 to slide and adjust its height. After releasing, the third return spring 45 pushes the J-shaped pressing block assembly 44 to reset, and the protrusion re-engages in the toothed groove to complete the locking. A leveling and adjusting plate 46 is fixedly connected between the two rectangular sliders 42. The leveling and adjusting plate 46 is located below the limiting clamping block 34, and its top surface is a flat support surface. After the workpiece is placed, it automatically levels itself by its own weight.

[0036] Overall working process of the device Before welding, the photovoltaic equipment components are placed on the top surface of the leveling and adjusting plate 46 and automatically leveled by their own weight. Rotating the handle 38 drives the two-way threaded rod 37 to move the limit clamping blocks 34 on both sides to move synchronously in the center. With the elastic compensation of the second reset spring 35, the workpiece is clamped in the center.

[0037] When the support height needs to be adjusted, press the J-shaped pressing blocks 44 on both sides to release the toothed locking, which will drive the rectangular slider 42 and the leveling and adjusting plate 46 to rise and fall for adjustment. After reaching the position, release to lock automatically.

[0038] When welding requires flipping, the control console 12 drives the hydraulic rod 24 to perform one extension and retraction cycle. The hydraulic rod 24 rises, causing the triangular rotating block 29 to rise, which in turn contacts the rectangular limiting plate 22 and triggers the rotating rod 27 to rotate 180 degrees, causing the positioning groove plate 31 and the workpiece to flip over. When the hydraulic rod 24 falls, the triangular rotating block 29 passes through the top gap of the rectangular limiting plate 22 and contacts the room-shaped trigger block 23, causing the rectangular limiting plate 22 to slide and reset, preparing for the next flipping.

[0039] After welding is completed, rotate the handle 38 in the opposite direction to release the limit clamping block 34, and then the workpiece can be removed.

[0040] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments: Workpiece placement and automatic leveling steps Before welding the photovoltaic equipment components, the components to be welded are placed on the top surface of the leveling and adjusting plate 46. Since the leveling and adjusting plates 46 on both sides are pre-adjusted to the same horizontal height, and the top surface of the leveling and adjusting plates 46 is a flat support surface, the photovoltaic equipment components automatically adhere to the top surface of the leveling and adjusting plates 46 by their own weight after placement, realizing automatic leveling of the workpiece. This ensures that the components to be welded on both sides are in the same reference plane, eliminating the need for manual leveling and correction, and providing a flat positioning reference for subsequent precise welding.

[0041] This solution uses a leveling and adjusting plate 46. After the workpiece is placed, it automatically fits the flat support surface by its own weight, achieving automatic leveling without the need for repeated manual leveling and correction. This reduces the leveling and adjustment time, provides a stable horizontal reference for welding, and ensures the consistency of the welding dimensions of the components.

[0042] Bidirectional centering clamping and positioning steps After the workpiece is leveled, the worker holds the workpiece to maintain stability and rotates the handle 38. Rotating the handle 38 drives the bidirectional threaded rod 37 to rotate synchronously. During the rotation of the bidirectional threaded rod 37, the threaded transmission drives the two side limit sliders 36 to move synchronously towards the center along the bottom of the positioning groove plate 31. The two side limit sliders 36 respectively drive the top strip slider 33 to move synchronously towards the center along the inside of the positioning groove plate 31. When the strip slider 33 moves, it simultaneously drives the limiting clamping block 34 and the second reset spring 35 to move closer to the workpiece. The limiting clamping blocks 34 on both sides gradually abut against the outer walls of both sides of the workpiece, pushing the workpiece to move towards the center position of the positioning groove plate 31, thereby realizing the automatic centering and positioning of the workpiece.

[0043] After the limiting clamping block 34 contacts the workpiece, the second return spring 35 is compressed, generating an elastic compensation force. This ensures effective clamping and pre-tightening of the workpiece while preventing surface damage and deformation caused by rigid extrusion, thus adapting to the clamping requirements of workpieces of different thicknesses. Simultaneously, the threaded drive between the bidirectional threaded rod 37 and the limiting slider 36 has a mechanical self-locking characteristic, meaning the limiting slider 36 can only be driven by the bidirectional threaded rod 37; it cannot be driven in the opposite direction. This effectively prevents clamping loosening due to vibration during welding, ensuring welding positioning accuracy.

[0044] By using a bidirectional threaded rod 37 to drive the two side limit sliders 36 to move synchronously in the center, the limit clamping block 34 is driven to achieve bidirectional centering clamping of the workpiece. With the elastic compensation of the second return spring 35, it can not only ensure effective clamping preload, but also avoid surface damage and deformation of the workpiece caused by rigid extrusion, which is suitable for clamping requirements of photovoltaic components of different thicknesses. At the same time, the threaded drive has a self-locking characteristic, which can prevent the clamping from loosening due to vibration and thermal deformation during the welding process, and ensure positioning stability.

[0045] Adjustable clamping height adaptation steps For photovoltaic equipment components with different heights and welding positions, the support height of the leveling and adjusting plate 46 can be adjusted. Simultaneously pressing the J-shaped pressing block assemblies 44 on both sides causes them to slide along the rectangular slider 42 towards the positioning block 43, simultaneously compressing the third return spring 45. The protrusions at the ends of the J-shaped pressing block assemblies 44 retract inward, disengaging from the toothed grooves on the inner wall of the positioning toothed plate assembly 41, releasing the vertical locking constraint of the rectangular slider 42. At this point, the J-shaped pressing block assemblies 44 can drive the rectangular slider 42 to slide vertically along the positioning toothed plate assembly 41, thereby causing the leveling and adjusting plate 46 to rise or fall, adjusting it to a support height suitable for the workpiece size.

[0046] After adjustment, the J-shaped pressing block assembly 44 is released, the third reset spring 45 extends elastically, pushing the J-shaped pressing block assembly 44 to reset outwards. The end protrusion re-engages into the corresponding height groove of the positioning tooth plate assembly 41, locking the position of the rectangular slider 42 again, thus completing the height adjustment. This adjustment structure can quickly adapt to photovoltaic equipment components of different heights, expanding the applicability of the device.

[0047] This solution features a height-adjustable leveling adjustment structure. By pressing the J-shaped pressing block group 44 to release the lock, the rectangular slider 42 can be driven to slide vertically along the positioning tooth plate group 41 to adjust the support height of the leveling adjustment plate 46. After releasing, it automatically locks into the tooth groove, which can quickly adapt to photovoltaic components of different heights and sizes, expanding the applicability of the device.

[0048] Mechanical flipping and turning steps When photovoltaic equipment components need to be flipped for welding during the welding process, the hydraulic rod 24 is started by the control console 12. The hydraulic rod 24 performs one extension and retraction cycle, first rising and then falling. When the hydraulic rod 24 rises, it drives the lifting seat 25 to rise synchronously. The lifting seat 25 drives the triangular rotating block 29 to rise synchronously through the rotating rod 27.

[0049] During its ascent, the triangular rotating block 29 contacts the rectangular limiting plate 22. Blocked by the rectangular limiting plate 22, the triangular rotating block 29 drives the rotating rod 27 to rotate around the hinge point of the lifting seat 25, simultaneously stretching the first return spring 28. When the rotating rod 27 rotates past the vertical center line, the first return spring 28 elastically contracts, pulling the rotating rod 27 to quickly flip until the other end of the rotating rod 27 abuts the limiting rod 26, completing a 180-degree flip and limiting. The triangular rotating block 29 flips 180 degrees synchronously with the rotating rod 27, passing through the top gap of the rectangular limiting plate 22, thereby causing the positioning groove plate 31 and the clamped workpiece to flip 180 degrees, achieving workpiece flipping.

[0050] Subsequently, the hydraulic rod 24 retracts and descends, causing the lifting seat 25, rotating rod 27, and triangular rotating block 29 to descend synchronously. During the descent, the triangular rotating block 29 passes through the top gap of the rectangular limiting plate 22. Then, the inclined surface of the triangular rotating block 29 abuts against the room-shaped trigger block 23, pushing the room-shaped trigger block 23 to drive the rectangular limiting plate 22 to slide to one side along the top of the moving seat 21, so that the rectangular limiting plate 22 moves again to the path directly above the triangular rotating block 29 for the next rise, preparing for the next flip.

[0051] Each triggering of the hydraulic rod's 24-cycle extension and retraction can drive the workpiece to complete a 180-degree flip, eliminating the need for manual disassembly and reassembly or manual flipping. It is especially suitable for double-sided welding operations of large-sized photovoltaic equipment components, reducing the labor intensity and safety risks of manual flipping, and ensuring that the workpiece maintains its original centered positioning after flipping, resulting in good consistency in the welding position.

[0052] The triangular rotating block 29 and the positioning groove plate 31 can be rotated 180 degrees in one extension and retraction cycle by the hydraulic rod 24, so as to realize the automatic flipping of the workpiece. There is no need for manual disassembly and reassembly or manual handling, which reduces the labor intensity and safety risks of flipping large-sized components. After flipping, the workpiece still maintains its original centered clamping state, avoiding positioning errors caused by repeated clamping and ensuring the alignment accuracy of the weld seam in double-sided welding.

[0053] Spacing adaptation and continuous welding effect The control console 12 allows the two movable seats 21 to move horizontally along the top of the welding worktable 11, adjusting the spacing between the two flipping components to accommodate photovoltaic equipment components of different lengths. The flipping and fixing components work together to achieve integrated workpiece clamping, leveling, and flipping. When flipping is required during welding, there is no need for re-clamping and repositioning; mechanical flipping is completed directly by hydraulic drive. After flipping, the workpiece retains its original centered positioning, effectively reducing positioning errors caused by repeated clamping and improving welding quality and continuous operation efficiency.

[0054] The movable seats 21 on both sides of this solution can be moved horizontally along the welding worktable 11 to adjust the spacing, adapting to photovoltaic components of different lengths and specifications; the device integrates automatic leveling, centering clamping, height adjustment, and mechanical flipping, with each process closely connected, reducing the auxiliary time of multiple clamping, and improving the continuous operation efficiency of double-sided welding of large-size photovoltaic components.
