[0001] This application relates to the technical field of laser welding equipment, and more particularly, to a laser welding equipment for new energy vehicle parts. Background Art

[0002] The laser welding equipment for new energy vehicle parts is a high-precision processing tool designed for the manufacturing of key components of new energy vehicles. Its core advantages lie in its efficient, precise, and clean thermal processing capabilities, which can meet the special process requirements of components such as power batteries, drive motors, and body structures.

[0003] Currently, the laser welding equipment for new energy vehicle parts mainly uses fixtures to clamp workpieces for laser welding. Especially when processing parts with arc-shaped structures, special-shaped fixtures are required to clamp two arc-shaped parts. After clamping the arc-shaped workpieces with such special-shaped fixtures, it is generally difficult to flexibly adjust the position of the welded workpieces to cooperate with the laser welding equipment for welding both sides of the workpieces. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this purpose, this application proposes a laser welding equipment for new energy vehicle parts to solve the problem that it is generally difficult to flexibly adjust the position of the welded workpieces to cooperate with the laser welding equipment for welding both sides of the workpieces after clamping the arc-shaped workpieces with conventional special-shaped fixtures.

[0005] A laser welding equipment for new energy vehicle parts according to an embodiment of this application includes: a laser welding equipment main body, a universal adjustment mechanism, and a workpiece support adjustment mechanism.

[0006] The laser welding equipment main body includes a base, a welding assembly, and a lifting and mounting assembly, and both the welding assembly and the lifting and mounting assembly are installed above the base;

[0007] The lifting and mounting assembly drives the universal adjustment mechanism to move in the vertical direction;

[0008] The workpiece support adjustment mechanism includes a base plate, arc-shaped guide rails, a limiting frame with an arc-shaped structure, a rotation driving member, arc-shaped sliding rails, and magnet blocks. The universal adjustment mechanism drives the base plate to move and adjust. Two groups of arc-shaped guide rails are respectively fixed on both sides above the base plate. The rotation driving member is installed on the base plate to drive the arc-shaped sliding rails to slide and cooperate along the arc-shaped guide rails. The end of the limiting frame is fixedly connected to the arc-shaped sliding rails. A strip plate is arranged in the slot inside the limiting frame, and the magnet blocks are fixedly embedded in the mounting openings on the strip plate.

[0009] Place the two arc-structured parts in the limit frame of the workpiece support adjustment mechanism, and the magnet blocks on the internal strip board of the limit frame will adsorb and position the metal parts. The lifting and installation component can drive the universal adjustment mechanism to move in the vertical direction, that is, drive the parts inside the limit frame to move and adjust in the vertical direction. The universal adjustment mechanism can drive the parts inside the limit frame to be adjusted to any position, and cooperate with the welding component to complete the welding operation. The rotation driving part can drive the arc-shaped slide rail to move along the arc-shaped guide rail, that is, the arc-shaped parts inside the limit frame can move along the arc-shaped guide rail to adjust the welding position, so that the other side of the arc-shaped parts inside the limit frame can be welded through the opening under the arc-shaped guide rail. That is, the laser welding equipment for new energy vehicle parts can perform various position adjustments on the magnetically adsorbed arc-shaped metal parts, which is convenient for the welding component to weld different surfaces of the parts. Without putting down the workpiece during a single welding operation, multi-surface adjustment welding can be directly carried out, improving the welding processing efficiency of arc-shaped parts.

[0010] In some embodiments of the present application, the welding component includes a welding head and a support arm. The bottom of the support arm is fixedly arranged with the base, and the welding head is installed on the top of the support arm.

[0011] In some embodiments of the present application, the lifting and installation component includes a fixed seat, a sliding seat, a hydraulic cylinder and a bracket. The fixed seat is fixedly arranged with the base, the hydraulic cylinder is installed above the fixed seat to drive the sliding seat to lift, and the bracket is connected with the sliding seat.

[0012] In some embodiments of the present application, the lifting and installation component further includes a protective cover shell, which is located outside the hydraulic cylinder and is detachably installed with the fixed seat.

[0013] In some embodiments of the present application, the universal adjustment mechanism includes a universal movement component and a seat frame. The universal movement component includes a first motor, a second motor, a third motor, a first connecting arm and a second connecting arm. The first motor is installed at the end of the bracket to drive the first connecting arm to rotate, the second motor is installed at the other end of the first connecting arm to drive the second connecting arm to rotate, and the third motor is installed at the other end of the second connecting arm.

[0014] In some embodiments of the present application, the seat frame includes an upper shelf board, a lower shelf board and a connecting block. The output shaft end of the third motor is connected with the upper shelf board, and the lower shelf board is fixedly connected with the upper shelf board through the connecting block.

[0015] In some embodiments of the present application, a first through hole is provided on the lower shelf board, and the lower shelf board passes through and is located outside the third motor.

[0016] In some embodiments of the present application, a second through hole is provided on the bottom board, and the bottom board passes through and is located outside the third motor.

[0017] In some embodiments of the present application, the rotation driving member includes a driving motor and a driving block. The driving motor is installed above the bottom plate, and the driving block is fixedly sleeved at the end of the output shaft of the driving motor.

[0018] In some embodiments of the present application, an avoidance opening for avoiding the driving block is provided at the bottom end of the arc-shaped guide rail.

[0019] The laser welding equipment for new energy vehicle parts further includes a pneumatic actuator. The pneumatic actuator includes an air shell, a piston, a pull rod, and an air pipe. A sealing gasket is provided on the magnet block, and a ventilation hole is provided in the middle of the magnet block. The air shell is located below the limit frame, and the end face of the air shell is fixedly connected to the arc-shaped guide rail. The piston is located inside the air shell. One end of the pull rod is fixedly connected to the piston, and the other end of the pull rod slides through the air shell and is connected to the bottom of the strip plate in the limit frame. One end of the air pipe penetrates through the strip plate and is communicated with the bottom of the ventilation hole. The side of the piston away from the pull rod and the air shell form a pneumatic cavity, and the other end of the air pipe is communicated with the pneumatic cavity inside the air shell.

[0020] When two arc-shaped parts are placed inside the limit frame, the welding areas above the two parts are in a horizontal position. After the upper welding is completed, the arc-shaped slide rail can be driven to rotate by the rotation driving member, that is, finally drive the limit frame to rotate to adjust the position of the bottom of the internal parts to be inclined outside the seat frame. Then, in cooperation with the universal adjustment mechanism and the lifting and installation assembly, the other welding surface originally located at the bottom can be rotated and adjusted to the upper surface, and welding operations can be carried out in cooperation with the welding assembly. If the parts are non-magnetic parts, when the arc-shaped slide rail drives the limit frame to rotate and adjust the position, the strip plate in the limit frame moving along the arc-shaped guide rail will also drive the pull rod to move. The moving pull rod will drive the piston to move inside the air shell. The space in the pneumatic cavity inside the air shell becomes larger and the air pressure decreases. Through the air pipe and the ventilation hole, the cavity between the magnet block and the sealing gasket above can be tightly adsorbed on the surface of the part. That is, the magnet block and the sealing gasket enclose a suction cup structure that can adsorb the surface of the workpiece. And this adsorption method has a good adsorption and positioning effect during the process of the gradually increasing rotation angle of the limit frame. As the inclination angle of the internal parts in the limit frame gradually increases, the cavity on the magnet block and the sealing gasket is more tightly adsorbed on the surface of the part.

[0021] In some embodiments of the present application, the sealing gasket includes a base cushion layer, an outer edge layer, and a convex edge layer. An outer edge groove is provided on the outer edge of the top of the magnet block. A through hole is provided in the middle of the base cushion layer, and the base cushion layer is fixedly sleeved in the outer edge groove. The outer edge layer is integrally formed on the outer edge of the top of the base cushion layer, and the inner wall of the outer edge layer is inclined. The annular convex edge layer is provided in the middle of the inclined surface of the outer edge layer, and small holes are provided on the bottom side edge of the convex edge layer.

[0022] The inner wall of the convex edge layer and the inclined surface of the outer edge layer form an adsorption cavity. Through the cooperation of the small holes, the outer wall of the convex edge layer and the inclined outer edge layer form another adsorption cavity. That is, when the gasket contacts the workpiece surface to form negative pressure, two adsorption cavities can be formed for hierarchical adsorption, which can increase the adsorption contact area between the gasket and the workpiece, improve the adsorption capacity of the parts, and further improve the positioning effect of the workpiece inside the limit frame.

[0023] The beneficial effects of this application are as follows: A laser welding device for new energy vehicle parts obtained through the above design. The magnet blocks on the strip board inside the limit frame adsorb and position the metal parts. The lifting and mounting assembly cooperates with the universal adjustment mechanism to adjust the parts to any position to complete the welding operation. The rotation driving part can drive the arc-shaped slide rail to move along the arc-shaped guide rail, that is, the arc-shaped parts inside the limit frame can move along the arc-shaped guide rail to adjust the welding position, so that the other side of the arc-shaped parts inside the limit frame can pass through the opening under the arc-shaped guide rail for welding operation. That is, it realizes multi-position adjustment of the magnetically adsorbed arc-shaped metal parts, facilitates the welding assembly to weld different surfaces of the parts, and does not need to put down the workpiece during a single welding operation, and can directly perform multi-surface adjustment welding, improving the welding processing efficiency of the arc-shaped parts.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0039] Accordingly, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0040] A laser welding device for new energy vehicle parts according to an embodiment of the present application will be described below with reference to the drawings.

[0041] Please refer to Figures 1-9 , a laser welding device for new energy vehicle parts according to an embodiment of the present application includes: a laser welding device main body 10, a universal adjustment mechanism 20, and a workpiece support adjustment mechanism 30.

[0042] Among them, the workpiece support adjustment mechanism 30 is used to position two arc-shaped structural parts, can adjust the angle of the positioned parts, cooperate with the universal adjustment mechanism 20 to adjust the position of the parts, and cooperate with the laser welding device main body 10 to flexibly complete double-sided welding.

[0043] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 , the laser welding device main body 10 includes a base 110, a welding assembly 120, and a lifting and mounting assembly 130. The welding assembly 120 and the lifting and mounting assembly 130 are both installed above the base 110. The lifting and mounting assembly 130 drives the universal adjustment mechanism 20 to move in the vertical direction. The workpiece support adjustment mechanism 30 includes a bottom plate 310, arc-shaped guide rails 320, a limiting frame 330 with an arc-shaped structure, a rotation driving member 340, arc-shaped slide rails 350, and magnet blocks 360. The universal adjustment mechanism 20 drives the bottom plate 310 to move and adjust. Two groups of arc-shaped guide rails 320 are respectively fixed on both sides above the bottom plate 310. The rotation driving member 340 is installed on the bottom plate 310 to drive the arc-shaped slide rails 350 to slide and cooperate along the arc-shaped guide rails 320. The end of the limiting frame 330 is fixedly connected to the arc-shaped slide rails 350. A strip plate is arranged in the slot inside the limiting frame 330, and the magnet blocks 360 are fixedly embedded in the mounting openings on the strip plate.

[0044] The working principle of the laser welding equipment for new energy vehicle parts is as follows: Place two parts with arc-shaped structures in the limit frame 330 of the workpiece support adjustment mechanism 30. The magnet blocks 360 on the inner strip of the limit frame 330 adsorb and position the metal parts. The lifting and mounting assembly 130 can drive the universal adjustment mechanism 20 to move in the vertical direction, that is, drive the parts inside the limit frame 330 to move and adjust in the vertical direction. The universal adjustment mechanism 20 can drive the parts inside the limit frame 330 to be adjusted to any position, and cooperate with the welding assembly 120 to complete the welding operation. The rotation driving part 340 can drive the arc-shaped slide rail 350 to move along the arc-shaped guide rail 320, that is, the arc-shaped parts inside the limit frame 330 can move along the arc-shaped guide rail 320 to adjust the welding position, so that the other side of the arc-shaped parts inside the limit frame 330 can be welded through the opening under the arc-shaped guide rail 320. That is, the laser welding equipment for new energy vehicle parts can perform various position adjustments on the magnetically adsorbed arc-shaped metal parts, facilitating the welding assembly 120 to weld different surfaces of the parts. Without putting down the workpiece during a single welding operation, multi-surface adjustment welding can be directly carried out, improving the welding processing efficiency of the arc-shaped parts.

[0045] For specific settings, please refer to Figure 1 , the welding assembly 120 includes a welding head 121 and a support arm 122. The bottom of the support arm 122 is fixedly arranged with the base 110. The support arm 122 and the base 110 can be fixed by bolts. The welding head 121 is installed on the top of the support arm 122. The welding head 121 is a common laser welding head device, and the welding head 121 can perform welding processing operations on parts.

[0046] Specifically, please refer to Figure 2 , the lifting and mounting assembly 130 includes a fixed seat 131, a sliding seat 132, a hydraulic cylinder 133 and a bracket 134. The fixed seat 131 is fixedly arranged with the base 110 by bolts. The hydraulic cylinder 133 is installed above the fixed seat 131 to drive the sliding seat 132 to lift and lower. The bracket 134 is connected to the sliding seat 132. The output rod end of the hydraulic cylinder 133 drives the sliding seat 132 to move in the vertical direction, that is, drives the universal adjustment mechanism 20 to perform a large-distance movement adjustment in the vertical direction.

[0047] Furthermore, the lifting and mounting assembly 130 also includes a protective cover shell, which is detachably installed on the fixed seat 131 outside the hydraulic cylinder 133. The protective cover shell is used to protect the hydraulic cylinder 133.

[0048] In the above specific implementation manner, please refer to Figure 3 and Figure 4, the universal adjustment mechanism 20 includes a universal movement component 210 and a seat frame 220. The universal movement component 210 includes a first motor 211, a second motor 212, a third motor 213, a first connecting arm 214, and a second connecting arm 215. The first motor 211 is installed at the end of the bracket 134 to drive the first connecting arm 214 to rotate. The second motor 212 is installed at the other end of the first connecting arm 214 to drive the second connecting arm 215 to rotate. The third motor 213 is installed at the other end of the second connecting arm 215.

[0049] The first motor 211 in the universal movement component 210 drives the first connecting arm 214 to rotate, the second motor 212 drives the second connecting arm 215 to rotate, and the third motor 213 drives the upper shelf plate 221 to rotate. This enables the seat frame 220 to adjust its position in all three axes. That is, it drives the components in the limit frame 330 to move to the required positions.

[0050] Furthermore, the seat frame 220 includes an upper shelf plate 221, a lower shelf plate 222, and a connecting block 223. The output shaft end of the third motor 213 is connected to the upper shelf plate 221, and the lower shelf plate 222 is fixedly connected to the upper shelf plate 221 through the connecting block 223. The third motor 213 drives the upper shelf plate 221 in the seat frame 220 to rotate, and drives the lower shelf plate 222 to move together through the connecting block 223. Among them, the bottom plate 310 is fixedly arranged with the lower shelf plate 222.

[0051] Specifically, the lower shelf plate 222 is provided with a first through hole, and the lower shelf plate 222 passes through the outside of the third motor 213. The bottom plate 310 is provided with a second through hole, and the bottom plate 310 passes through the outside of the third motor 213. The rotation driving member 340 includes a driving motor 341 and a driving block 342. The driving motor 341 is installed above the bottom plate 310, and the driving block 342 is fixedly sleeved on the output shaft end of the driving motor 341. The driving motor 341 in the rotation driving member 340 drives the arc-shaped slide rail 350 to move through the friction between the driving block 342 and the arc-shaped slide rail 350. A corresponding anti-movement structure can also be set between the driving motor 341 and the driving block 342, such as improving the stability of the arc-shaped slide rail 350 after rotation adjustment through the self-locking structure of the worm and worm gear.

[0052] Furthermore, the bottom end of the arc-shaped guide rail 320 is provided with an avoidance opening for avoiding the driving block 342.

[0053] The limit frame 330 in the above-mentioned laser welding equipment for new energy vehicle parts is only suitable for fixing metal parts that can be magnetically attracted by the magnet block 360, and cannot perform positioning processing operations on some workpieces that cannot be magnetically attracted.

[0054] Please refer to Figure 6 , Figure 7 and Figure 8, the laser welding equipment for new energy vehicle parts further includes a pneumatic actuator 40, which includes an air shell 410, a piston 420, a pull rod 430 and an air pipe 440. A sealing gasket 370 is arranged on the magnet block 360, and a ventilation hole 361 is arranged in the middle of the magnet block 360. The air shell 410 is located below the limit frame 330, and the end face of the air shell 410 is fixedly connected to the arc-shaped guide rail 320. The piston 420 is located inside the air shell 410. One end of the pull rod 430 is fixedly connected to the piston 420, and the other end of the pull rod 430 slides through the air shell 410 and is connected to the bottom of the strip plate in the limit frame 330. One end of the air pipe 440 penetrates through the strip plate and is communicated with the bottom of the ventilation hole 361. The side of the piston 420 away from the pull rod 430 and the air shell 410 form a pneumatic cavity, and the other end of the air pipe 440 is communicated with the pneumatic cavity inside the air shell 410.

[0055] When two arc-shaped parts are placed inside the limit frame 330, the welding areas above the two parts are in a horizontal position. After the upper welding is completed, the arc-shaped slide rail 350 can be driven to rotate by rotating the driving part 340, that is, finally drive the limit frame 330 to rotate to adjust the position of the bottom of the internal parts to be inclined outside the seat frame 220. Then, with the cooperation of the universal adjustment mechanism 20 and the lifting and installation component 130, the other welding surface originally located at the bottom can be rotated and adjusted to the upper surface, and welding operations can be carried out in cooperation with the welding component 120. If the parts are non-magnetic adsorption parts, when the arc-shaped slide rail 350 drives the limit frame 330 to rotate and adjust the position, the strip plate in the limit frame 330 moving along the arc-shaped guide rail 320 will also drive the pull rod 430 to move. The moving pull rod 430 will drive the piston 420 to move inside the air shell 410. The space in the pneumatic cavity inside the air shell 410 becomes larger and the air pressure decreases. Through the air pipe 440 and the ventilation hole 361, the cavity between the upper part of the magnet block 360 and the sealing gasket 370 can be tightly adsorbed on the part surface. That is, the magnet block 360 and the sealing gasket 370 enclose a suction cup structure that can adsorb the workpiece surface. And this adsorption method, during the process of the gradually increasing rotation angle of the limit frame 330, as the inclination angle of the internal parts in the limit frame 330 gradually increases, the cavity on the magnet block 360 and the sealing gasket 370 is also more tightly adsorbed on the part surface, having a good adsorption and positioning effect.

[0056] If the parts to be welded and processed are magnetic workpieces, not only can they be positioned by magnetic adsorption of the magnet block 360, but at the same time, the cavity formed by the sealing gasket 370 can further adsorb the part surface for positioning, improving the positioning stability of the parts during welding processing.

[0057] The sealing gasket 370 in the above-mentioned laser welding equipment for new energy vehicle parts encloses a general suction cup structure, and its adsorption ability is relatively general. If the adsorption structure can be designed and adjusted, the role of adsorbing and positioning parts can be further improved.

[0058] For specific settings, please refer to Figure 6 , Figure 8 and Figure 9 , the gasket 370 includes a base cushion layer 371, an outer edge layer 373 and a convex edge layer 374. An outer edge groove 362 is provided on the outer edge of the top of the magnet block 360. A through hole 372 is provided in the middle of the base cushion layer 371, and the base cushion layer 371 is fixedly sleeved in the outer edge groove 362. The outer edge layer 373 is integrally formed on the outer edge of the top of the base cushion layer 371, and the inner wall of the outer edge layer 373 is arranged as an inclined surface. The annular convex edge layer 374 is arranged in the middle of the inclined surface of the outer edge layer 373, and small holes 375 are provided on the bottom side edge of the convex edge layer 374.

[0059] Among them, the base cushion layer 371, the outer edge layer 373 and the convex edge layer 374 are integrally formed. The inner wall of the convex edge layer 374 and the inclined surface of the outer edge layer 373 form an adsorption cavity groove. Through the cooperation of the small holes 375, the outer wall of the convex edge layer 374 and the inclined outer edge layer 373 form another adsorption cavity groove. That is, when the gasket 370 is in contact with the workpiece surface to form negative pressure, two adsorption cavity grooves can be formed for hierarchical adsorption, which can increase the adsorption contact area between the gasket 370 and the workpiece and improve the adsorption ability of the gasket to the parts, that is, further improve the positioning effect of the workpiece inside the limit frame 330.

[0060] It should be noted that the specific model specifications of the above hydraulic cylinder 133, the first motor 211, the second motor 212, the third motor 213, and the drive motor 341 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail. The power supply and principle of the hydraulic cylinder 133, the first motor 211, the second motor 212, the third motor 213, and the drive motor 341 are clear to those skilled in the art, and will not be described in detail here.
