[0034] See also Figures 1 to 5 , Figure 1 1 is a schematic structural diagram of a welding device 1000 according to an embodiment of the present invention; Figure 2 yes Figure 1 A structural schematic diagram of the welding device 1000 from another perspective; Figure 3 yes Figure 1A schematic structural diagram of the side welding device 300 and the back welding device 400 and the frame 100 in the welding equipment 1000; Figure 4 yes Figure 3 A schematic structural diagram of the side welding device 300 and the Y-direction slide rail 103 on the frame 100; Figure 5 yes Figure 4 Schematic diagram of the structure of the side welding device 300 and the y-axis slide rail 103 on the frame 100 from another perspective. An embodiment of the present invention provides a welding device 1000, which includes a frame 100 and a side welding device 300, and the side welding device 300 is installed on the frame 100. The side welding device 300 includes a y-axis motion mechanism 31, a first x-axis motion mechanism 32, a first z-axis motion mechanism 33, a first biaxial rotation module 34 and a side welding unit 35 connected in sequence, the first x-axis motion mechanism 32, the y-axis motion mechanism 31 and the first z-axis motion mechanism 33 are used to cooperate with the first biaxial rotation module 34 to drive the side welding unit 35 to move along the x-axis direction, the y-axis direction and the z-axis direction, the first biaxial rotation module 34 is used to drive the side welding unit 35 to rotate around the z-axis and the axis perpendicular to the z-axis, and the side welding unit 35 is used to weld the weldment to the side of the product.

[0035] Specifically, the frame 100 is constructed from multiple welded metal pipes. A side welding device 300 is mounted at the bottom of the frame 100, facilitating welding of products placed within the frame 100. The welding equipment 1000 also includes a top welding device 200, a back welding device 400, a workbench 500, a transfer station 600, and a feed station 700. The back welding device 400 is mounted at the bottom of the frame 100, facilitating welding of the back of the product. The top welding device 200 is mounted at the top of the frame 100, facilitating welding of the top surface of the product. The workbench 500 is mounted at the center of the bottom of the frame 100 and is used to secure the fuel tank product. The transfer station 600 is located adjacent to the workbench 500 to facilitate loading and unloading of the fuel tank product. The feed station 700 is located adjacent to the transfer station 600 to transport the fuel tank product away after welding. It should be noted that the welding equipment 1000 provided by the present invention can be used not only for welding fuel tanks, but also for welding other components such as batteries.

[0036] It will be understood that the y-axis motion mechanism 31 is mounted on the frame 100 and can drive the first x-axis motion mechanism 32, the first z-axis motion mechanism 33, the first biaxial rotation module 34, and the side welding unit 35 to move relative to the frame 100 along the y-axis direction. The first x-axis motion mechanism 32 is mounted on the y-axis motion mechanism 31 and can drive the first z-axis motion mechanism 33, the first biaxial rotation module 34, and the side welding unit 35 to move relative to the y-axis motion mechanism 31 along the x-axis direction. The first z-axis motion mechanism 33 is mounted on the first x-axis motion mechanism 32 and can drive the first biaxial rotation module 34 and the side welding unit 35 to move relative to the first x-axis motion mechanism 32 along the z-axis direction. The first biaxial rotation module 34 is mounted on the first z-axis motion mechanism 33 and can drive the side welding unit 35 to rotate relative to the first z-axis motion mechanism 33 about the z-axis and an axis perpendicular to the z-axis. In this way, the side welding unit 35 can move along the x-axis, y-axis and z-axis directions, rotate around the z-axis, and rotate around an axis perpendicular to the z-axis.

[0037] It is understandable that the side of a fuel tank product is different from other surfaces and is relatively more complex. In some fuel tank products, there may be areas on the side that are constructed as bevels (the angle formed with the horizontal plane is an acute angle), and the contour of the side generally extends along a curve (the bevel and the contour extending along the curve may exist at the same time). During welding, the weldment needs to be welded to the welding position on the side of the product in a direction perpendicular to the side. In the welding equipment 1000 provided in the embodiment of the present invention, the side welding unit 35 can be driven to rotate about the z-axis by the first dual-axis rotation module 34, so that the side welding unit 35 can adapt to the welding requirements of the side of the product with a curved contour, and the side welding unit 35 can be driven to rotate about the axis perpendicular to the z-axis by the first dual-axis rotation module 34, so that the side welding unit 35 can adapt to the welding requirements of the bevel area on the side.

[0038] By arranging a y-axis motion mechanism 31, a first x-axis motion mechanism 32, a first z-axis motion mechanism 33 and a first dual-axis rotation module 34 between the frame 100 and the side welding unit 35, the y-axis motion mechanism 31, the first x-axis motion mechanism 32 and the first z-axis motion mechanism 33 can cooperate to drive the first dual-axis rotation module 34 to drive the side welding unit 35 to move along the x-axis direction, the y-axis direction and the z-axis direction, so that the side welding unit 35 can adapt to move to the welding position on the side of the product. At the same time, the first dual-axis rotation module 34 drives the side welding unit 35 to rotate around the z-axis and to rotate along two axes perpendicular to the z-axis to adjust the weldment to be opposite to the welding position on the side. The side welding unit 35 can weld the weldment to the welding position, so that it can adapt to the processing requirements of different products without the need for workers to frequently adjust. The welding is more versatile and the processing efficiency is improved.

[0039] In some embodiments, multiple side welding devices 300 are used to simultaneously weld products at multiple closely spaced welding locations. The presence of the first dual-axis rotation module 34 allows the side welding units 35 of the multiple side welding devices 300 to avoid each other, preventing interference that could prevent simultaneous welding.

[0040] In one embodiment of this embodiment, please refer to Figure 4 and Figure 5 The y-direction motion mechanism 31 includes a y-direction driving member 311 and a y-direction slide 312.

The first z-direction motion mechanism 33 includes a first z-direction driver 331 and a first z-direction slide 332. The first x-direction slide 322 is provided with a first z-direction slide rail 323 that slidably engages with the first z-direction slide 332. The first z-direction driver 331 is mounted on the first x-direction slide 322 and connected to the first z-direction slide 332. The first dual-axis rotation mechanism is mounted on the first z-direction slide 332. This arrangement enables high-precision movement of the side welding unit 35 relative to the frame 100 in the x-axis, y-axis, and z-axis directions.

[0041] In one embodiment of this embodiment, please refer to Figure 4 、 Figure 5 and Figure 7 , Figure 7 yes Figure 4 Schematic diagram of the structure of the first dual-axis rotation module 34 and the first z-direction slide 332 in the side welding device 300.

This arrangement allows for a reduced transmission to be achieved through the cooperation between the first gear 3413 and the second gear 3414, thereby increasing the output torque to the second connecting base 3422 and improving the rotational accuracy and reliability of the side welding unit 35.

[0047] Specifically, the second connecting seat 3422 is inserted into the first connecting seat 3412 , and the fourth gear 3424 is installed at one end thereof. The side welding unit 35 is installed on the end surface of the fourth gear 3424 .

The hot mold assembly 352 is used to heat the weldment and the product to a molten state, while the fixed assembly 353 is used to secure the weldment and press the molten weldment onto the product. Specifically, the reference plate 351 is mounted on the end surface of the fourth gear 3424. In this arrangement, the hot mold assembly 352 and the fixed assembly 353 are both installed on the reference plate 351, and the reference plate 351 is connected to the first biaxial rotation module 34, so that the first biaxial rotation module 34 can drive the reference plate 351 to drive the hot mold assembly 352 and the fixed assembly 353 to perform biaxial rotation movement synchronously, so that the weldment on the fixed assembly 353 is located in the normal direction of the welding position on the side of the product, the fixed assembly 353 can press the weldment down onto the product, and the heating surface of the hot mold assembly 352 is located in the normal direction of the welding position on the side of the product, and the hot mold assembly 352 can heat the product.

[0051] In one embodiment of this embodiment, please refer to Figure 8 The hot die assembly 352 includes a first hot die head 3521, a second hot die head 3522 and a first translation drive member 3523. The first hot die head 3521 is fixed on the reference plate 351. The first translation drive member 3523 is set on the reference plate 351 and connected to the second hot die head 3522. The first translation drive member 3523 is used to drive the second hot die head 3522 to move to abut against the product. The fixed assembly 353 includes a clamping structure 3531 and a second translation drive member 3532. The second translation drive member 3532 is set on the reference plate 351 and connected to the clamping structure 3531. The second translation drive member 3532 is used to drive the clamping structure 3531 to drive the weldment to move to abut against the first hot die head 3521 and the product respectively.

[0052] By securing the first hot die head 3521 to the reference plate 351, the second translational drive 3532 can drive the clamping structure 3531 to move the weldment into contact with the first hot die head 3521, thereby heating the weldment. Furthermore, the second hot die head 3522 and the first translational drive 3523 are provided, and the first translational drive 3523 can drive the second hot die head 3522 into contact with the product, thereby heating the product. In this way, the product and weldment are heated by separate hot die heads, allowing both to simultaneously enter a molten state, thereby improving weld quality. Furthermore, the separate hot die heads can effectively shorten the welding stroke of the clamping structure 3531 (the stroke required for the second translational drive 3532 to drive the clamping structure 3531), facilitating the welding of large products in environments with limited space. Furthermore, the second translational drive 3532 can simultaneously heat the weldment and fuse the weldment to the product, resulting in a relatively simple structure and lowering costs.

[0053] In one embodiment of this embodiment, please refer to Figure 8 In order to reduce costs and improve welding accuracy, the first translation drive member 3523 and the second translation drive member 3532 are both constructed as cylinders and are arranged in parallel.

[0054] In one embodiment of this embodiment, please refer to Figure 8 The heating surface of the first hot die head 3521 faces opposite to the heating surface of the second hot die head 3522. With this arrangement, the weldment and the product can be heated from both sides by the corresponding hot die heads, saving horizontal space.

[0055] Specifically, Figure 8 The heating surface of the first hot die head 3521 is shown to be generally facing right, and the heating surface of the second hot die head 3522 is shown to be generally facing left.

[0056] In one embodiment of this embodiment, please refer to Figures 8 to 10 , Figure 9 yes Figure 8 A schematic structural diagram of the welding unit in the side welding device 300 from another perspective; Figure 10 yes Figure 4 Schematic diagram of the structure of the welding unit in the side welding device 300 when the offset movable base 3541 is in the first position. The side welding unit 35 includes a dislocation drive mechanism 354, which includes a dislocation movable base 3541 and a dislocation drive member 3542. A first translation drive member 3523 and a second translation drive member 3532 are both disposed on the dislocation movable base 3541. The dislocation drive member 3542 is disposed on the reference plate 351 and connected to the dislocation movable base 3541. The dislocation drive member 3542 is used to drive the dislocation movable base 3541 to move between the first position and the second position. When the dislocation movable base 3541 is in the first position, the clamping structure 3531 is opposite to the first hot die head 3521, and the second hot die head 3522 is opposite to the welding position of the product. When the dislocation movable base 3541 is in the second position, the clamping structure 3531 is opposite to the welding position of the product. It is understood that after the offset driver 3542 drives the offset movable seat 3541 to move to the first position, the second translation driver 3532 can drive the clamping structure 3531 to move the weldment to abut against the first hot die head 3521. Simultaneously, the first translation driver 3523 can drive the second hot die head 3522 to abut against the welding position of the product, so that the weldment and the welding position of the product are simultaneously heated to a molten state to ensure welding quality. The offset driver 3542 then drives the offset movable seat 3541 from the first position to the second position, so that the second translation driver 3532 can drive the clamping structure 3531 to move the molten weldment to abut against the molten welding position of the product, thereby completing the fusion welding. In addition, during the welding process, the second translation driver 3532 can take into account the driving components of both weldment heating and weldment welding, simplifying the structure and reducing costs, which is conducive to reducing the horizontal dimension of the side welding unit 35.

[0057] In one embodiment of this embodiment, please refer to Figures 8 to 10 The offset drive mechanism 354 includes a first movable base 3543 and a second movable base 3544, both of which are slidably engaged with the offset movable base 3541. The second hot die head 3522 is disposed on the first movable base 3543, and the clamping structure 3531 is disposed on the second movable base 3544. This arrangement improves the movement accuracy of the second hot die head 3522 and the clamping structure 3531, thereby improving welding quality.

[0058] In one embodiment of this embodiment, Figure 8 and Figure 11, Figure 11 yes Figure 9 A schematic diagram of the structure of the clamping structure 3531 in the welding unit. Clamping structure 3531 is detachably connected to the second movable seat 3544 and is used to clamp and fix a weldment of matching shape. This arrangement allows for quick removal and replacement of the clamping structure 3531 for a specific product when processing different products, improving the versatility and efficiency of the welding process.

[0059] Specifically, the clamping structure 3531 includes a fixed block 35313, a first quick-release block 35314, a second quick-release block 35315, a rotating block 35316, and a clamping body 35317, which are connected in sequence. The fixed block 35313 is fixedly connected to the second movable seat 3544. The first quick-release block 35314 and the second quick-release block 35315 are fastened together to enable quick removal and installation. The rotating block 35316 and the second quick-release block 35315 have multiple installation positions. In different installation positions, the relative angles of the rotating block 35316 and the second quick-release block 35315 around an axis parallel to the driving direction of the second translational driver 3532 vary, facilitating alignment of the weldment with the product. The clamping body 35317 defines a mounting slot whose shape matches the weldment, and the weldment is clamped and fixed within the mounting slot. Due to the quick-release connection between the first quick-release block 35314 and the second quick-release block 35315 , the dedicated clamping body 35317 can be replaced in a timely manner.

[0060] In some embodiments, the clamping structure 3531 includes a rotation adjustment mechanism (not shown) and a camera, which are both mounted on the second movable seat 3544. The rotation adjustment mechanism is connected to the fixed block 35313 and is used to drive the fixed block 35313 to drive the clamping body 35317 and the weldment to rotate relative to the product around an axis parallel to the driving direction of the second translation drive member 3532. The camera is used to obtain an image of the product so that the rotation adjustment mechanism can adjust the weldment to align with the product based on the image.

[0061] In one embodiment of this embodiment, please refer to Figures 8 to 10 The offset movable seat 3541 is slidably engaged with the reference plate 351. This arrangement can improve the movement accuracy of the offset movable seat 3541, so as to ensure that the weldment on the clamping structure 3531 can be aligned with the first hot die head 3521, and the second hot die head 3522 can be aligned with the welding position of the product.

[0062] Specifically, the direction in which the offset moving seat 3541 slides relative to the reference plate 351 is perpendicular to the axis around which the second rotating mechanism 342 drives the reference plate 351 to rotate.

[0063] Specifically, the offset movable seat 3541 and the reference plate 351 , the first movable seat 3543 and the offset movable seat 3541 , and the second movable seat 3544 and the offset movable seat 3541 all achieve sliding fit by adopting a guide rail and a guide groove fit.

[0064] In one embodiment of this embodiment, please refer to Figures 8 to 10 When the offset movable seat 3541 is in the second position, the first hot die head 3521 and the second hot die head 3522 are respectively located on either side of the clamping structure 3531 in the driving direction of the offset driving member 3542. This arrangement allows the clamping structure 3531 to avoid the first hot die head 3521 and face the product when the offset movable seat 3541 is in the second position, facilitating welding of the welded parts.

[0065] In one embodiment of this embodiment, please refer to Figures 8 to 10 When the offset movable seat 3541 is in the second position, the distance between the clamping structure 3531 and the first hot die head 3521 is equal to the distance between the clamping structure 3531 and the second hot die head 3522 in the driving direction of the offset driving member 3542. This arrangement allows the position of the clamping structure 3531 when the offset movable seat 3541 is in the second position to coincide with the position of the second hot die head 3522 when the offset movable seat 3541 is in the first position, thereby facilitating alignment of the weldment on the clamping structure 3531 and the second hot die head 3522 with the weld position of the product.

[0066] In one embodiment of this embodiment, please refer to Figures 8 to 10 The driving directions of the first translation driving member 3523 and the second translation driving member 3532 are parallel and perpendicular to the driving direction of the offset driving member 3542. This arrangement facilitates heating and welding of the weldment and the product, and is conducive to improving welding accuracy.

[0067] In this embodiment, the y-direction driving member 311, the first x-direction driving member 321 and the first z-direction driving member 331 all use motor screws to achieve linear drive, and the first translation driving member 3523, the second translation driving member 3532 and the offset driving member 3542 all use cylinder drive to achieve linear drive, and the output push rod of the cylinder (not shown) is connected to the corresponding moving parts.

[0068] In one embodiment of this embodiment, please refer to Figure 6 , Figure 6 yes Figure 3Schematic diagram of the structure of the back welding device 400 and the second x-axis slide rail 104 on the frame 100. The back welding device 400 includes a second x-axis motion mechanism 41, a second z-axis motion mechanism 42, a second two-axis rotation module 43 and a back welding unit 44 connected in sequence. The second x-axis motion mechanism 41 and the second z-axis motion mechanism 42 are used to cooperate with the second two-axis rotation module 43 to drive the back welding unit 44 to move along the x-axis and z-axis directions. The second two-axis rotation module 43 is used to drive the back welding unit 44 to rotate around the z-axis and an axis perpendicular to the z-axis. The back welding unit 44 is used to weld the weldment to the back of the product. It can be understood that the second x-axis motion mechanism 41 and the second z-axis motion mechanism 42 can cooperate to drive the second two-axis rotation module 43 to drive the back welding unit 44 to move along the x-axis direction and the z-axis direction, so that the back welding unit 44 can adapt to move to the welding position on the back of the product. At the same time, the second two-axis rotation module 43 drives the back welding unit 44 to rotate around the z-axis and rotate on two axes perpendicular to the z-axis to adjust the weldment to be opposite to the welding position on the back. The back welding unit 44 can weld the weldment to the welding position, and can realize simultaneous welding of the side and back of the product with the side welding device 300, thereby further improving the processing efficiency.

[0069] Specifically, the second x-axis motion mechanism 41 is mounted on the frame 100 and can drive the second z-axis motion mechanism 42, the second two-axis rotation module 43, and the back welding unit 44 to move along the x-axis relative to the frame 100. The second z-axis motion mechanism 42 is mounted on the second x-axis motion mechanism 41 and can drive the second two-axis rotation module 43 and the back welding unit 44 to move along the z-axis relative to the second x-axis motion mechanism 41. The second two-axis rotation module 43 is mounted on the second z-axis motion mechanism 42 and can drive the back welding unit 44 to rotate about the z-axis and an axis perpendicular to the z-axis relative to the second z-axis motion mechanism 42. In this way, the back welding unit 44 can move along the x-axis and z-axis directions, rotate about the z-axis, and rotate about an axis perpendicular to the z-axis.

[0070] In one embodiment of this embodiment, please refer to Figure 1 and Figure 6The second x-axis motion mechanism 41 includes a second x-axis drive member 411 and a second x-axis slide 412. The frame 100 is provided with a second x-axis slide rail 104 that slidably cooperates with the second x-axis slide 412. The second x-axis drive member 411 is mounted on the frame 100 and connected to the second x-axis slide 412. The second z-axis motion mechanism 42 includes a second z-axis drive member 421 and a second z-axis slide 422. The second x-axis slide 412 is provided with a second z-axis slide rail 413 that slidably cooperates with the second z-axis slide 422. The second z-axis drive member 421 is mounted on the second x-axis slide 412 and connected to the second z-axis slide 422. The second two-axis rotation mechanism is mounted on the second z-axis slide 422. This arrangement enables high-precision movement of the back welding unit 44 relative to the frame 100 in the x-axis and z-axis directions.

[0071] It should be noted that the specific structure of the back welding unit 44 in the back welding device 400 can refer to the side welding unit 35 in the side welding device 300, and the specific structure of the second biaxial rotation module 43 in the back welding device 400 can refer to the first biaxial rotation module 34 in the side welding device 300. Compared with the side welding unit 35, the movement in the y-axis direction between the back welding unit 44 and the frame 100 is cancelled. By reasonably setting the position of the workbench 500, the back welding unit 44 and the product on the workbench 500 have an appropriate distance in the y-axis direction, so there is no need for movement in the y-axis direction.

[0072] The welding steps of the side welding device 300 of the welding equipment 1000 provided in this embodiment are as follows: Step 1: The y-axis motion mechanism 31, the first x-axis motion mechanism 32, the first z-axis motion mechanism 33, and the first biaxial rotation module 34 cooperate to drive the side welding unit 35 to move along the y-axis, x-axis, and z-axis directions, and to rotate around the z-axis and an axis perpendicular to the z-axis, so that the side welding unit 35 is in a suitable position. At this time, the offset moving seat 3541 is in the first position, the clamping structure 3531 is opposite to the first hot die head 3521, and the second hot die head 3522 is opposite to the welding position of the product; Step 2: The first translation drive 3523 drives the second hot die head 3522 to move to abut against the welding position of the product, thereby heating the welding position of the product to a molten state. At the same time, the second translation drive 3532 drives the clamping structure 3531 to move the weldment to abut against the first hot die head 3521, thereby heating the weldment to a molten state. Step 3: The first translation drive 3523 drives the second hot die head 3522 to move and separate from the product. At the same time, the second translation drive 3532 drives the clamping structure 3531 to move the weldment to separate from the first hot die head 3521. Step 4: The dislocation driving member 3542 drives the dislocation movable seat 3541 to move to the second position, so that the clamping structure 3531 is opposite to the welding position of the product; Step 5: The second translation drive 3532 drives the clamping structure 3531 to move the weldment to weld with the product.

Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention.
