Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a side welding unit. Background Technology

[0002] The fuel tank is an important component of vehicles such as automobiles that use gasoline as their power source. Fuel tanks typically require welding of components such as fuel nozzles, hose clamps, carbon canister brackets, support blocks, and isolation valve brackets to facilitate the assembly of surrounding parts and the operation of the fuel tank.

[0003] In existing technologies, welding equipment typically uses a dedicated side welding unit to weld the sides of fuel tank products. This existing side welding unit employs a single hot die head to simultaneously heat both the workpiece and the product. After heating, the hot die head, driven by relevant drive components, moves away from the welding path of the workpiece and product, allowing the workpiece to fuse with the product under this driving force. This structure results in a relatively long welding stroke, making it difficult to weld large fuel tank products in space-constrained environments. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a side welding unit that enables the welding of large-sized fuel tank products in environments with limited space.

[0005] This utility model provides a side welding unit, which includes: a reference plate; a hot mold assembly including a first hot mold head, a second hot mold head, and a first translational drive member, wherein the first hot mold head is disposed on the reference plate, the first translational drive member is disposed on the reference plate and connected to the second hot mold head, and the first translational drive member is used to drive the second hot mold head to move to abut against the product, so that the second hot mold head heats the product to a molten state; and a fixing assembly including a clamping structure and a second translational drive member, wherein the second translational drive member is disposed on the reference plate and connected to the clamping structure, the clamping structure is used to clamp the weldment, the second translational drive member is used to drive the clamping structure to move the weldment to abut against the first hot mold head, so that the first hot mold head heats the weldment to a molten state, and the second translational drive member is also used to drive the clamping structure to move the weldment to weld with the product.

[0006] The side welding unit provided in the first aspect of this utility model has at least the following beneficial effects:

[0007] By setting the first hot die head on the reference plate, the second translation drive can drive the clamping structure to move the workpiece to contact the first hot die head, thereby heating the workpiece. Alternatively, by setting the second hot die head and the first translation drive, the first translation drive can drive the second hot die head to contact the product, thereby heating the product. In this way, the product and the workpiece are heated by independent hot dies, which can effectively shorten the welding stroke of the clamping structure (the stroke of the clamping structure driven by the second translation drive), making it easier to weld large-sized products in environments with limited space.

[0008] In one embodiment of this implementation, the side welding unit includes a misalignment driving mechanism, which includes a misalignment moving seat and a misalignment driving member. The first translation driving member and the second translation driving member are both disposed on the misalignment moving seat. The misalignment driving member is disposed on the reference plate and connected to the misalignment moving seat. The misalignment driving member is used to drive the misalignment moving seat to move between a first position and a second position. When the misalignment moving seat is located in the first position, the clamping structure is opposite to the first hot die head, and the second hot die head is opposite to the welding position of the product. When the misalignment moving seat is located in the second position, the clamping structure is opposite to the welding position of the product.

[0009] In one embodiment of this implementation, when the misaligned moving seat is in the second position, the first hot mold head and the second hot mold head are respectively located on both sides of the clamping structure in the driving direction of the misaligned driving member.

[0010] In one embodiment of this implementation, when the misaligned moving seat is in the second position, the distance between the clamping structure and the first hot mold head and the distance between the second hot mold head and the clamping structure are equal in the driving direction of the misaligned driving member.

[0011] In one embodiment of this implementation, the misalignment driving mechanism includes a first movable seat and a second movable seat, both of which are slidably engaged with the misalignment movable seat. The second hot mold head is disposed on the first movable seat, and the clamping structure is disposed on the second movable seat.

[0012] In one embodiment of this implementation, the clamping structure is detachably connected to the second movable seat and is used to clamp and fix the weldment with a matching shape.

[0013] In one embodiment of this implementation, both the first translation drive and the second translation drive are constructed as cylinders and arranged in parallel.

[0014] In one embodiment of this implementation, the misaligned moving seat is slidably engaged with the reference plate.

[0015] In one embodiment of this implementation, the driving directions of the first translational drive and the second translational drive are parallel and both perpendicular to the driving direction of the misalignment drive.

[0016] In one embodiment of this implementation, the first hot mold head is fixed on the reference plate, and the heating surface of the first hot mold head faces opposite directions to the heating surface of the second hot mold head.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0045] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of a welding device 1000 according to one embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the welding equipment 1000 from another perspective; Figure 3 yes Figure 1 A schematic diagram of the structure of the side welding device 300 and the back welding device 400 in the welding equipment 1000 and the frame 100; Figure 4 yes Figure 3 A schematic diagram of the structure of the side welding device 300 and the y-direction slide rail 103 on the frame 100; Figure 5 yes Figure 4 A schematic diagram of the side welding device 300 and the y-axis slide rail 103 on the frame 100 from another perspective. This utility model provides a welding device 1000, which includes a frame 100 and a side welding device 300 mounted 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 dual-axis rotation module 34, and a side welding unit 35 connected in sequence. The first x-axis motion mechanism 32, y-axis motion mechanism 31, and first z-axis motion mechanism 33 cooperate to drive the first dual-axis rotation module 34 to move the side welding unit 35 along the x-axis, y-axis, and z-axis directions. The first dual-axis rotation module 34 drives the side welding unit 35 to rotate around the z-axis and an axis perpendicular to the z-axis. The side welding unit 35 is used to weld the workpiece to the side of the product.

[0046] Specifically, the frame 100 is constructed as a frame formed by welding multiple metal pipes. A side welding device 300 is installed at the bottom of the frame 100 to facilitate welding of products placed inside the frame. The welding equipment 1000 also includes a top welding device 200, a back welding device 400, a worktable 500, a transition table 600, and a feeding table 700. The back welding device 400 is installed at the bottom of the frame 100 to facilitate welding of the back of the product. The top welding device 200 is installed at the top of the frame 100 to facilitate welding of the top surface of the product. The worktable 500 is installed at the center of the bottom of the frame 100 and is used to fix the fuel tank product. The transition table 600 is located adjacent to the worktable 500 to assist in loading and unloading the fuel tank product. The feeding table 700 is located adjacent to the transition table 600 to transport the fuel tank product after welding is completed. It should be noted that the welding equipment 1000 provided by this utility model can be used not only for welding fuel tanks, but also for welding other components such as batteries.

[0047] Understandably, 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 dual-axis 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 dual-axis 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 dual-axis 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 dual-axis 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. This allows the side welding unit 35 to move along the x-axis, y-axis, and z-axis, as well as rotate around the z-axis and around an axis perpendicular to the z-axis.

[0048] Understandably, the sides of fuel tank products differ from other surfaces, being relatively more complex. In some fuel tank products, certain areas of the side may be constructed as slopes (forming an acute angle with the horizontal plane), and the side profile typically extends along a curve (sloping surfaces and curved profiles may coexist). During welding, the workpiece needs to be welded to the welding position on the side of the product along a direction perpendicular to the side. In the welding equipment 1000 provided in this embodiment of the invention, the side welding unit 35 can be driven to rotate around the z-axis by the first dual-axis rotation module 34, enabling the side welding unit 35 to adapt to the welding requirements of the side profile of the product, which extends along a curve, and the side welding unit 35 can also be driven to rotate around an axis perpendicular to the z-axis by the first dual-axis rotation module 34, enabling the side welding unit 35 to adapt to the welding requirements of the sloped areas on the side.

[0049] By setting 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 move the side welding unit 35 along the x-axis, y-axis, and z-axis directions, so that the side welding unit 35 adapts 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 rotate along an axis perpendicular to the z-axis to adjust the workpiece to be opposite to the welding position on the side. The side welding unit 35 can weld the workpiece to the welding position. In this way, it can adapt to the processing requirements of different products, without the need for frequent adjustments by workers, and the welding versatility is strong, which improves the processing efficiency.

[0050] In some embodiments, there are multiple side welding devices 300, which simultaneously weld products at multiple densely arranged welding positions. 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 interference that would prevent the multiple side welding units 35 from welding simultaneously.

[0051] In one embodiment of this implementation, please refer to Figure 4 and Figure 5 The y-axis motion mechanism 31 includes a y-axis drive member 311 and a y-axis slide block 312. The frame 100 is provided with a y-axis slide rail 103 that slides and engages with the y-axis slide block 312. The y-axis drive member 311 is mounted on the frame 100 and connected to the y-axis slide block 312. The first x-axis motion mechanism 32 includes a first x-axis drive member 321 and a first x-axis slide block 322. The y-axis slide block 312 is provided with a first x-axis slide rail 313 that slides and engages with the first x-axis slide block 322. The first x-axis drive member 321 is mounted on the y-axis slide block 312 and connected to the first x-axis slide block 322. The first z-axis motion mechanism 33 includes a first z-axis drive member 331 and a first z-axis slide block 332. The first x-axis slide block 322 is provided with a first z-axis slide rail 323 that slides and engages with the first z-axis slide block 332. The first z-axis drive member 331 is mounted on the first x-axis slide block 322 and connected to the first z-axis slide block 332. The first dual-axis rotation mechanism is mounted on the first z-axis slide block 332. This configuration 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.

[0052] In one embodiment of this implementation, please refer to Figure 4 , Figure 5 and Figure 7 , Figure 7 yes Figure 4 The diagram shows the structure of the first dual-axis rotating module 34 and the first z-axis slide block 332 in the side welding device 300. The first dual-axis rotating module 34 includes a first rotating mechanism 341 and a second rotating mechanism 342. The first rotating mechanism 341 is mounted on the first z-axis motion mechanism 33 and connected to the second rotating mechanism 342. The side welding unit 35 is disposed on the second rotating mechanism 342. The first rotating mechanism 341 drives the second rotating mechanism 342 to rotate the side welding unit 35 around the z-axis, and the second rotating mechanism 342 drives the side welding unit 35 to rotate around an axis perpendicular to the z-axis. With this configuration, the first rotating mechanism 341 and the second rotating mechanism 342 can work together to achieve the rotation of the side welding unit 35 around the z-axis and the axis perpendicular to the z-axis.

[0053] In one embodiment of this implementation, please refer to Figure 4 , Figure 5 and Figure 7 The first rotating mechanism 341 includes a first rotating drive member 3411 and a first connecting seat 3412. The first connecting seat 3412 is rotatably mounted on a first z-axis motion mechanism 33 about the z-axis. The first rotating drive member 3411 is mounted on the first z-axis motion mechanism 33 and connected to the first connecting seat 3412. The second rotating mechanism 342 includes a second rotating drive member 3421 and a second connecting seat 3422. The second connecting seat 3422 is rotatably mounted on the first connecting seat 3412 along an axis perpendicular to the z-axis. The second rotating drive member 3421 is mounted on the first connecting seat 3412 and connected to the second connecting seat 3422. The side welding unit 35 is disposed on the second connecting seat 3422. With this configuration, under the drive of the first rotating drive member 3411 and the second rotating drive member 3421, the second connecting seat 3422 can drive the side welding unit 35 to rotate about the z-axis and an axis perpendicular to the z-axis.

[0054] Specifically, the first rotary drive 3411 is mounted on the first z-axis slide 332, and the first connecting seat 3412 is mounted on the first z-axis slide 332 via bearings, so that the first connecting seat 3412 can rotate relative to the first z-axis slide 332 around the z-axis.

[0055] In one embodiment of this implementation, please refer to Figure 4 , Figure 5 and Figure 7 The first rotary drive component 3411 is provided with a first gear 3413, and the first connecting seat 3412 is provided with a second gear 3414 that meshes with the first gear 3413. The number of teeth of the first gear 3413 is less than the number of teeth of the second gear 3414. With this arrangement, speed reduction transmission can be achieved through the cooperation of the first gear 3413 and the second gear 3414, thereby increasing the output torque on the first connecting seat 3412 and improving the rotational accuracy and reliability of the side welding unit 35.

[0056] Specifically, the first connecting seat 3412 passes through the first z-axis slide 332, the second gear 3414 is located at the top of the first connecting seat 3412, and the second connecting seat 3422 is mounted on the end face of the second gear 3414.

[0057] In one embodiment of this implementation, please refer to Figure 4 , Figure 5 and Figure 7The second rotary drive component 3421 is equipped with a third gear 3423, and the second connecting seat 3422 is equipped with a fourth gear 3424 that meshes with the third gear 3423. The number of teeth of the third gear 3423 is less than the number of teeth of the fourth gear 3424. With this arrangement, speed reduction transmission can be achieved through the cooperation of the first gear 3413 and the second gear 3414, thereby increasing the output torque on the second connecting seat 3422 and improving the rotational accuracy and reliability of the side welding unit 35.

[0058] Specifically, the second connecting seat 3422 passes through the first connecting seat 3412, and a fourth gear 3424 is installed at one end of it, with the side welding unit 35 installed on the end face of the fourth gear 3424.

[0059] In one embodiment of this implementation, please refer to Figure 3 The product has two side welding devices 300, which are arranged opposite each other to weld the workpiece to the two opposite sides of the product. Specifically, the two side welding devices 300 have identical structures. This arrangement allows for simultaneous welding of both sides of the product, improving processing efficiency.

[0060] Specifically, the two side welding devices 300 are used to weld the nozzle, support block, isolation valve bracket and pipe clamp to the corresponding welding positions on the side of the oil tank product.

[0061] The side welding unit 35 provided in the embodiments of this utility model will be described in detail below.

[0062] In one embodiment of this implementation, please refer to Figure 8 , Figure 8 yes Figure 4 A schematic diagram of the welding unit in the side welding device 300 when the misaligned moving seat 3541 is in the second position. The side welding unit 35 includes a reference plate 351, a hot mold assembly 352, and a fixing assembly 353. The hot mold assembly 352 includes a first hot mold head 3521, a second hot mold head 3522, and a first translation drive 3523. The first hot mold head 3521 is disposed on the reference plate 351, and the first translation drive 3523 is disposed on the reference plate 351 and connected to the second hot mold head 3522. The first translation drive 3523 is used to drive the second hot mold head 3522 to move to abut against the product. The fixing assembly 353 includes a clamping structure 3531 and a second translation drive 3532. The second translation drive 3532 is disposed on the reference plate 351 and connected to the clamping structure 3531. The second translation drive 3532 is used to drive the clamping structure 3531 to move the weldment to abut against the first hot mold head 3521 and the product, respectively.

[0063] Specifically, the reference plate 351 is mounted on the end face of the fourth gear 3424. With this configuration, both the hot mold assembly 352 and the fixing assembly 353 are mounted on the reference plate 351. The reference plate 351 is connected to the first dual-axis rotating module 34, enabling the first dual-axis rotating module 34 to drive the reference plate 351 to synchronously rotate the hot mold assembly 352 and the fixing assembly 353. This allows the weldment on the fixing assembly 353 to be positioned in the normal direction of the welding position on the side of the product, allowing the fixing assembly 353 to press the weldment onto the product. Additionally, the heating surface of the hot mold assembly 352 is positioned in the normal direction of the welding position on the side of the product, allowing the hot mold assembly 352 to heat the product.

[0064] By fixing the first hot die head 3521 to the base plate 351, the second translation drive 3532 can drive the clamping structure 3531 to move the workpiece to abut against the first hot die head 3521, thereby heating the workpiece. Furthermore, by setting up the second hot die head 3522 and the first translation drive 3523, the first translation drive 3523 can drive the second hot die head 3522 to abut against the product, thereby heating the product. In this way, the product and the workpiece are heated by independent hot dies, effectively shortening the welding stroke of the clamping structure 3531 (the stroke by which the second translation drive 3532 drives the clamping structure 3531), facilitating the welding of large-sized products in space-constrained environments. Additionally, the separate arrangement of the hot dies allows the product and the workpiece to simultaneously enter the molten state, improving welding quality. Moreover, the second translation drive 3532 can simultaneously heat the workpiece and fuse it with the product, resulting in a simpler structure and reduced costs.

[0065] In one embodiment of this implementation, please refer to Figure 8 In order to reduce costs and improve welding accuracy, the first translation drive 3523 and the second translation drive 3532 are both constructed as cylinders and arranged in parallel.

[0066] In one embodiment of this implementation, please refer to Figure 8 The heating surface of the first hot die head 3521 faces opposite directions to the heating surface of the second hot die head 3522. This arrangement allows the workpiece and the product to be heated from both sides via their respective hot die heads, saving horizontal space.

[0067] Specifically, Figure 8 The heating surface of the first hot mold head 3521 is approximately facing right, and the heating surface of the second hot mold head 3522 is approximately facing left.

[0068] In one embodiment of this implementation, please refer to Figures 8 to 10 , Figure 9 yes Figure 8A schematic diagram of the welding unit in the side welding device 300 from another perspective; Figure 10 yes Figure 4 This is a schematic diagram of the welding unit in the side welding device 300 when the misaligned moving seat 3541 is in the first position. The side welding unit 35 includes a misalignment driving mechanism 354, which includes a misalignment moving seat 3541 and a misalignment driving member 3542. The first translation driving member 3523 and the second translation driving member 3532 are both disposed on the misalignment moving seat 3541. The misalignment driving member 3542 is disposed on the reference plate 351 and connected to the misalignment moving seat 3541. The misalignment driving member 3542 is used to drive the misalignment moving seat 3541 to move between the first position and the second position. When the misalignment 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. When the misalignment moving seat 3541 is in the second position, the clamping structure 3531 is opposite to the welding position of the product. Understandably, after the misalignment drive 3542 drives the misalignment moving seat 3541 to the first position, the second translation drive 3532 can drive the clamping structure 3531 to move the weldment to abut against the first hot die head 3521. Simultaneously, the first translation drive 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. Then, the misalignment drive 3542 drives the misalignment moving seat 3541 from the first position to the second position, allowing the second translation drive 3532 to drive the clamping structure 3531 to move the molten weldment to abut against the molten welding position of the product, thus completing the fusion welding. Furthermore, during the welding process, the second translation drive 3532 can simultaneously serve as the drive component for both weldment heating and weldment fusion, simplifying the structure and reducing costs, which is beneficial for minimizing the horizontal dimensions of the side welding unit 35.

[0069] In one embodiment of this implementation, please refer to Figures 8 to 10 The misalignment drive mechanism 354 includes a first movable seat 3543 and a second movable seat 3544, both of which are slidably fitted onto the misalignment movable seat 3541. A second hot die head 3522 is disposed on the first movable seat 3543, and a clamping structure 3531 is disposed on the second movable seat 3544. This arrangement can improve the movement accuracy of the second hot die head 3522 and the clamping structure 3531, which is beneficial to improving the welding quality.

[0070] In one embodiment of this implementation, Figure 8 and Figure 11 , Figure 11 yes Figure 9A schematic diagram of the clamping structure 3531 in the welding unit is shown. The clamping structure 3531 is detachably connected to the second movable seat 3544 and is used to clamp and fix the weldment with a matching shape. This arrangement allows for quick disassembly and replacement of the clamping structure 3531 with a dedicated clamping structure 3531 when processing different products, thereby improving the versatility of welding processing and increasing processing efficiency.

[0071] 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 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 achieve quick disassembly and installation through a snap-fit ​​engagement. The rotating block 35316 and the second quick-release block 35315 have multiple installation positions. In different installation positions, the relative angle between the rotating block 35316 and the second quick-release block 35315 around an axis parallel to the driving direction of the second translational drive member 3532 is different, facilitating alignment between the weldment and the product. The clamping body 35317 has an installation groove whose shape is adapted to the weldment, and the weldment is clamped and fixed within the installation groove. The quick-release connection between the first quick-release block 35314 and the second quick-release block 35315 allows the dedicated clamping body 35317 to be replaced in a timely manner.

[0072] In some embodiments, the clamping structure 3531 includes a rotation adjustment mechanism (not shown) and a camera. Both the rotation adjustment mechanism and the camera are 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 rotate the clamping body 35317 and the weldment relative to the product about an axis parallel to the driving direction of the second translation drive 3532. The camera is used to acquire an image of the product so that the rotation adjustment mechanism can adjust the weldment to be aligned with the product according to the image.

[0073] In one embodiment of this implementation, please refer to Figures 8 to 10 The misaligned moving seat 3541 slides in conjunction with the reference plate 351. This configuration improves the moving accuracy of the misaligned moving seat 3541, ensuring that the weldment on the clamping structure 3531 is aligned with the first hot die head 3521, and that the second hot die head 3522 is aligned with the welding position of the product.

[0074] Specifically, the direction in which the misaligned moving seat 3541 slides relative to the reference plate 351 is perpendicular to the axis around which the reference plate 351 rotates driven by the second rotating mechanism 342.

[0075] Specifically, the misaligned moving seat 3541 and the reference plate 351, the first moving seat 3543 and the misaligned moving seat 3541, the second moving seat 3544 and the misaligned moving seat 3541 all adopt the sliding fit of guide rail and guide groove.

[0076] In one embodiment of this implementation, please refer to Figures 8 to 10 When the misalignment moving seat 3541 is in the second position, the first hot die head 3521 and the second hot die head 3522 are respectively located on both sides of the clamping structure 3531 in the driving direction of the misalignment driving member 3542. This arrangement allows the clamping structure 3531 to avoid the first hot die head 3521 and face the product when the misalignment moving seat 3541 is in the second position, so as to facilitate welding.

[0077] In one embodiment of this implementation, please refer to Figures 8 to 10 When the misalignment moving seat 3541 is in the second position, the distance between the clamping structure 3531 and the first hot die head 3521 and the distance between the second hot die head 3522 and the clamping structure 3531 are equal in the driving direction of the misalignment driving member 3542. With this configuration, the position of the clamping structure 3531 when the misalignment moving seat 3541 is in the second position coincides with the position of the second hot die head 3522 when the misalignment moving seat 3541 is in the first position, so that the weldment on the clamping structure 3531 and the second hot die head 3522 are aligned with the welding position of the product, respectively.

[0078] In one embodiment of this implementation, please refer to Figures 8 to 10 The driving directions of the first translation drive 3523 and the second translation drive 3532 are parallel and both perpendicular to the driving direction of the misalignment drive 3542. This arrangement facilitates the heating and welding of the workpiece and the product, and helps to improve welding accuracy.

[0079] In this embodiment, the y-axis drive member 311, the first x-axis drive member 321 and the first z-axis drive member 331 are all driven linearly by a motor lead screw. The first translation drive member 3523, the second translation drive member 3532 and the misalignment drive member 3542 are all driven linearly by a cylinder. The output push rod of the cylinder (not shown) is connected to the corresponding moving part.

[0080] In one embodiment of this implementation, please refer to Figure 6 , Figure 6 yes Figure 3A schematic diagram 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 dual-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 in driving the second dual-axis rotation module 43 to move the back welding unit 44 along the x-axis and z-axis directions. The second dual-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 workpiece to the back of the product. Understandably, the second x-axis motion mechanism 41 and the second z-axis motion mechanism 42 can cooperate to drive the second dual-axis rotation module 43 to move the back welding unit 44 along the x-axis and z-axis directions, so that the back welding unit 44 adapts to move to the welding position on the back of the product. At the same time, the second dual-axis rotation module 43 drives the back welding unit 44 to rotate around the z-axis and rotate along an axis perpendicular to the z-axis to adjust the workpiece to be opposite to the welding position on the back. The back welding unit 44 can weld the workpiece to the welding position, and can achieve simultaneous welding of the side and back of the product with the side welding device 300, further improving processing efficiency.

[0081] 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 dual-axis rotation module 43, and the back welding unit 44 to move relative to the frame 100 along the x-axis. The second z-axis motion mechanism 42 is mounted on the second x-axis motion mechanism 41 and can drive the second dual-axis rotation module 43 and the back welding unit 44 to move relative to the second x-axis motion mechanism 41 along the z-axis. The second dual-axis rotation module 43 is mounted on the second z-axis motion mechanism 42 and can drive the back welding unit 44 to rotate relative to the second z-axis motion mechanism 42 about the z-axis and an axis perpendicular to the z-axis. This allows the back welding unit 44 to move along the x-axis and z-axis, rotate about the z-axis, and rotate about an axis perpendicular to the z-axis.

[0082] In one embodiment of this implementation, 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 block 412. The frame 100 is provided with a second x-axis slide rail 104 that slides with the second x-axis slide block 412. The second x-axis drive member 411 is mounted on the frame 100 and connected to the second x-axis slide block 412. The second z-axis motion mechanism 42 includes a second z-axis drive member 421 and a second z-axis slide block 422. The second x-axis slide block 412 is provided with a second z-axis slide rail 413 that slides with the second z-axis slide block 422. The second z-axis drive member 421 is mounted on the second x-axis slide block 412 and connected to the second z-axis slide block 422. A second dual-axis rotation mechanism is mounted on the second z-axis slide block 422. This configuration enables high-precision movement of the back welding unit 44 relative to the frame 100 in the x-axis and z-axis directions.

[0083] It should be noted that the specific structure of the back welding unit 44 in the back welding device 400 can be referenced to the side welding unit 35 in the side welding device 300, and the specific structure of the second dual-axis rotating module 43 in the back welding device 400 can be referenced to the first dual-axis rotating module 34 in the side welding device 300. Compared with the side welding unit 35, the back welding unit 44 eliminates the need for movement in the y-axis direction between itself and the frame 100. By properly setting the position of the worktable 500, the back welding unit 44 and the product on the worktable 500 can be kept at a suitable distance in the y-axis direction, thus eliminating the need for movement in the y-axis direction.

[0084] The welding steps of the side welding device 300 of the welding equipment 1000 provided in this embodiment are as follows:

[0085] 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 dual-axis rotation module 34 work together to drive the side welding unit 35 to move along the y-axis, x-axis and z-axis, and rotate around the z-axis and the axis perpendicular to the z-axis, so that the side welding unit 35 is in a suitable position. At this time, the misaligned moving seat 3541 is in the first position, the clamping structure 3531 is opposite to the first hot mold head 3521, and the second hot mold head 3522 is opposite to the welding position of the product.

[0086] Step 2: The first translation drive 3523 drives the second hot mold head 3522 to move to abut against the welding position of the product, so as to heat 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 mold head 3521, so as to heat the weldment to a molten state.

[0087] Step 3: The first translation drive 3523 drives the second hot mold head 3522 to move to 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 mold head 3521.

[0088] Step 4: The misalignment drive component 3542 drives the misalignment moving seat 3541 to move to the second position, so that the clamping structure 3531 is opposite to the welding position of the product;

[0089] Step 5: The second translation drive 3532 drives the clamping structure 3531 to move the weldment to the point of fusion with the product.
