Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a top surface welding device and welding equipment. 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 includes multiple welding units to weld the top surface of the fuel tank. Different welding units correspond to different welding positions on the top surface of the fuel tank. Because each welding unit occupies a significant amount of space, in scenarios where multiple welding positions are densely arranged on a fuel tank, welding can only be performed sequentially at each position. For example, after welding position 1, the welding unit needs to be adjusted to face position 2 before welding position 2, resulting in low processing efficiency. Utility Model Content

[0043] Please see Figures 1 to 3 , 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 multiple top surface welding devices 200 and the x-direction slide rail 101 on the frame 100 in the welding equipment 1000. This utility model provides a welding equipment 1000, which includes a frame 100 and multiple top surface welding devices 200 provided in this utility model embodiment. The multiple top surface welding devices 200 are mounted on the frame 100.

[0044] Specifically, the frame 100 is constructed as a frame formed by welding multiple metal pipes. Multiple top-side welding devices 200 are suspended from the top of the frame 100 to facilitate welding of products placed inside the frame 100.

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.

[0045] By adding multiple top surface welding devices 200 provided in this embodiment of the invention to the welding equipment 1000, the top surface welding units 25 of the multiple top surface welding devices 200 can simultaneously weld products with densely arranged welding positions, effectively improving processing efficiency.

[0046] Please see Figures 1 to 4 , Figure 4 yes Figure 3 A schematic diagram of the structure of a single top surface welding device 200 and an x-axis slide rail 101. This utility model provides a top surface welding device 200, which includes a top surface welding unit 25 and a z-axis rotation mechanism 24. The top surface welding unit 25 includes a reference plate 251, a hot mold assembly 252, and a fixing assembly 253. Both the hot mold assembly 252 and the fixing assembly 253 are mounted on the reference plate 251. The hot mold assembly 252 is used to heat the workpiece and product to a molten state, and the fixing assembly 253 is used to fix the workpiece and press the molten workpiece onto the top surface of the product. The z-axis rotation mechanism 24 is mounted on a frame 100 and is connected to the reference plate 251. The z-axis rotation mechanism 24 can drive the reference plate 251 to rotate the hot mold assembly 252 and the fixing assembly 253 relative to the frame 100 around a vertical z-axis.

[0047] By setting up a z-axis rotation mechanism 24, the top surface welding unit 25 can be driven to rotate relative to the frame 100 around the z-axis. When welding the top surface of the product, the top surface welding units 25 in the multiple top surface welding devices 200 can avoid each other and prevent interference. This allows for simultaneous welding of multiple densely arranged welding positions on the top surface of the product, improving processing efficiency. Furthermore, after the z-axis rotation mechanism 24 adjusts the top surface welding unit 25 into position, the top surface welding unit 25 can automatically weld the workpiece to the top surface of the product through the hot mold assembly 252 and the fixing assembly 253, further improving processing efficiency.

[0048] In this embodiment, the top surface welding device 200 further includes an x-axis motion mechanism 21, a y-axis motion mechanism 22, and a z-axis motion mechanism 23 connected in sequence. The x-axis motion mechanism 21 is mounted on the frame 100 and can drive the y-axis motion mechanism 22 to move the z-axis motion mechanism 23, the z-axis rotation mechanism 24, and the top surface welding unit 25 relative to the frame 100 along the x-axis direction. The y-axis motion mechanism 22 is mounted on the x-axis motion mechanism 21 and can drive the z-axis motion mechanism 23 to move the z-axis rotation mechanism 24 and the top surface welding unit 25 relative to the x-axis motion mechanism 21 along the y-axis direction. The z-axis motion mechanism 23 is mounted on the y-axis motion mechanism 22 and can drive the z-axis rotation mechanism 24 to move the top surface welding unit 25 relative to the y-axis motion mechanism 22 along the z-axis direction. The z-axis rotation mechanism 24 is mounted on the z-axis motion mechanism 23 and can drive the top surface welding unit 25 to rotate around the z-axis relative to the z-axis motion mechanism 23. This allows the top surface welding unit 25 to move along the x-axis, y-axis, and z-axis, as well as rotate around the z-axis. By setting x-axis motion mechanism 21, y-axis motion mechanism 22, z-axis motion mechanism 23, and z-axis rotation mechanism 24 between the frame 100 and the top surface welding unit 25, the x-axis motion mechanism 21, y-axis motion mechanism 22, and z-axis motion mechanism 23 can cooperate to drive the z-axis rotation mechanism 24 to move the top surface welding unit 25 along the x-axis, y-axis, and z-axis, enabling the top surface welding unit 25 to weld the workpiece to the welding position on the top surface of the product. This adapts to the processing needs of different products and improves processing efficiency.

[0049] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 The frame 100 is provided with an x-axis slide rail 101. The x-axis motion mechanism 21 includes an x-axis drive member 211 and an x-axis slide block 212. The x-axis slide block 212 is slidably engaged with the x-axis slide rail 101. The x-axis drive member 211 is mounted on the frame 100 and connected to the x-axis slide block 212. The y-axis motion mechanism 22 is mounted on the x-axis slide block 212. This configuration enables high-precision movement of the top surface welding unit 25 relative to the frame 100 in the x-axis direction.

[0050] In one embodiment of this implementation, please refer to Figures 3 to 5 , Figure 5 yes Figure 4 The diagram shows the top surface welding device 200 and the x-axis slide rail 101 from another perspective. The welding equipment 1000 includes multiple sets of top surface welding devices 200, with at least two devices in each set and multiple x-axis slide rails 101 arranged sequentially along the y-axis. The x-axis slide blocks 212 in each set of top surface welding devices 200 slide in slidably onto the same x-axis slide rail 101. This arrangement allows the x-axis slide blocks 212 of each set of top surface welding devices 200 to move along the same x-axis slide rail 101, simplifying the structure and reducing costs. It also improves the positional accuracy of the top surface welding units 25 within the same set and reduces the risk of interference.

[0051] In this embodiment, the welding equipment 1000 includes two sets of top surface welding devices 200, with two devices in each set, for a total of four top surface welding devices 200. The frame 100 is equipped with two x-axis slide rails 101, which are spaced apart along the y-axis. The two sets of top surface welding devices 200 are slidably engaged with their respective x-axis slide rails 101. This arrangement allows all four top surface welding devices 200 to simultaneously weld the top surface of the product. Specifically, in this embodiment, the four top surface welding devices 200 are used to weld the nozzle, support block, isolation valve bracket, and pipe clamp to the corresponding welding positions on the top surface of the oil tank product.

[0052] In one embodiment of this implementation, please refer to Figures 3 to 5 The y-axis motion mechanism 22 includes a y-axis drive member 221 and a y-axis slide block 222. The x-axis slide block 212 is provided with a y-axis slide rail 213, and the y-axis slide block 222 slides in cooperation with the y-axis slide rail 213. The y-axis drive member 221 is mounted on the x-axis slide block 212 and connected to the y-axis slide block 222. The z-axis motion mechanism 23 is mounted on the y-axis slide block 222. This configuration enables high-precision movement of the top surface welding unit 25 relative to the frame 100 in the y-axis direction.

[0053] In one embodiment of this implementation, please refer to Figures 3 to 5 The z-axis motion mechanism 23 includes a z-axis drive member 231 and a z-axis slide block 232. The y-axis slide block 222 is provided with a z-axis slide rail 223, and the z-axis slide block 232 slides in cooperation with the z-axis slide rail 223. The z-axis drive member 231 is mounted on the y-axis slide block 222 and connected to the z-axis slide block 232. The z-axis rotation mechanism 24 is mounted on the z-axis slide block 232. With this configuration, high-precision movement of the top surface welding unit 25 relative to the frame 100 in the z-axis direction can be achieved.

[0054] In one embodiment of this implementation, please refer to Figure 3, Figure 4 and Figure 7 , Figure 7 yes Figure 6 The diagram shows a partial structure of the z-axis rotation mechanism 24 and the z-axis slide 232 in the top surface welding device 200. The z-axis rotation mechanism 24 includes a z-axis rotation drive 241 and a rotating seat 242. The z-axis rotation drive 241 is mounted on the z-axis motion mechanism 23, and the rotating seat 242 is rotatably mounted on the z-axis motion mechanism 23. The top surface welding unit 25 is mounted on the rotating seat 242. The z-axis rotation drive 241 has a first gear 243, and the rotating seat 242 has a second gear 244. The first gear 243 and the second gear 244 mesh. With this configuration, the z-axis rotation drive 241 can drive the rotating seat 242 to rotate relative to the z-axis motion mechanism 23 through gear meshing, thereby enabling the top surface welding unit 25 to rotate relative to the frame 100 around the z-axis.

[0055] Specifically, the z-axis rotation drive 241 is mounted on the z-axis slide 232, and the rotating seat 242 is mounted on the z-axis slide 232 via bearings, so that the rotating seat 242 can rotate relative to the z-axis slide 232 around the z-axis. The rotating seat 242 passes through the z-axis slide 232, and a second gear 244 is provided at its bottom end.

[0056] In one embodiment of this implementation, please refer to Figure 4 and Figure 7 The number of teeth on the first gear 243 is less than the number of teeth on the second gear 244. This configuration allows for speed reduction transmission through the cooperation of the first gear 243 and the second gear 244, thereby increasing the output torque and improving the rotational accuracy and reliability of the top welding unit 25.

[0057] In one embodiment of this implementation, please refer to Figure 4 and Figure 6 , Figure 6 yes Figure 4A schematic diagram of the top surface welding unit 25 in the top surface welding device 200 is shown. The top surface welding unit 25 includes a reference plate 251, a hot mold assembly 252, and a fixing assembly 253. The reference plate 251 is connected to the z-axis rotation mechanism 24. Both the hot mold assembly 252 and the fixing assembly 253 are mounted on the reference plate 251. The hot mold assembly 252 is used to heat the workpiece and the product to a molten state, and the fixing assembly 253 is used to fix the workpiece and press the molten workpiece onto the product. With this configuration, the hot mold assembly 252 can heat the workpiece and the product simultaneously, which helps to improve welding efficiency. In addition, since both the hot mold assembly 252 and the fixed assembly 253 are mounted on the reference plate 251, and the reference plate 251 is connected to the z-axis rotation mechanism 24, the z-axis rotation mechanism 24 can drive the reference plate 251 to drive the hot mold assembly 252 and the fixed assembly 253 to rotate synchronously around the z-axis. This allows the weldment on the fixed assembly 253 to be positioned above the welding position of the product, and the fixed assembly 253 can press the weldment down onto the product. At the same time, driven by the z-axis rotation mechanism 24, the hot mold assembly 252 and the fixed assembly 253 in adjacent top surface welding units 25 are less likely to interfere with each other, so as to achieve multi-point synchronous welding and improve processing efficiency.

[0058] In this embodiment, the reference plate 251 is fixedly connected to the rotating seat 242, so that the rotating seat 242 can drive the reference plate 251 to rotate synchronously under the drive of the z-axis rotation drive member 241.

[0059] In one embodiment of this implementation, please refer to Figure 4 and Figure 6 The hot mold assembly 252 and the fixing assembly 253 are respectively installed on opposite sides of the base plate 251. This arrangement simplifies the structure and reduces the space occupied by the top welding unit 25.

[0060] In one embodiment of this implementation, please refer to Figure 4 and Figure 6The fixing assembly 253 includes a welding drive 2531 and a clamping structure 2532 for clamping the workpiece. The welding drive 2531 is mounted on the base plate 251 and connected to the clamping structure 2532. The hot mold assembly 252 includes a hot mold driver 2521 and a hot mold head 2522. The hot mold driver 2521 is mounted on the base plate 251 and connected to the hot mold head 2522. The hot mold driver 2521 is used to drive the hot mold head 2522 to move to the bottom side of the clamping structure 2532 so that the top side of the hot mold head 2522 is opposite to the workpiece in the z-axis direction. The hot mold driver 2521 is also used to drive the hot mold head 2522 to move to abut against the product. The welding drive 2531 is used to drive the clamping structure 2532 to move the workpiece along the z-axis direction so that the workpiece abuts against the hot mold head 2522 or the product. Specifically, the hot die head 2522 has an upper heating surface and a lower heating surface. The upper heating surface is used to heat the workpiece, and the lower heating surface is used to heat the product.

[0061] Understandably, the hot mold actuator 2521 drives the hot mold head 2522 to move to the bottom side of the clamping structure 2532 in the z-axis direction. At this time, the welding drive component 2531 can drive the workpiece to move downward along the z-axis direction by driving the clamping structure 2532, so that the workpiece abuts against the upper heating surface of the hot mold head 2522, thereby heating the workpiece. Additionally, the hot mold actuator 2521 can also drive the hot mold head 2522 to move closer to the product, so that the lower heating surface of the hot mold head 2522 abuts against the product, thereby heating the workpiece. This achieves automated heating of both the product and the workpiece by the hot mold head 2522. Simultaneously, after the workpiece is heated to a molten state, the hot mold actuator 2521 can drive the hot mold head 2522 away from the drive path of the welding drive component 2531 to avoid the clamping structure 2532. Then, the welding drive component 2531 drives the clamping structure 2532 to continue moving the workpiece along the z-axis direction, completing the automated welding of the workpiece and the product.

[0062] In one embodiment of this implementation, please refer to Figure 6 The thermal mold actuator 2521 includes a first thermal mold drive 2523 and a second thermal mold drive 2524. The first thermal mold drive 2523 is mounted on the base plate 251 and connected to the second thermal mold drive 2524. A thermal mold head 2522 is disposed on the second thermal mold drive 2524. The first thermal mold drive 2523 and the second thermal mold drive 2524 cooperate to drive the thermal mold head 2522 to move along the z-axis and in a direction perpendicular to the z-axis. With this configuration, the thermal mold actuator 2521 can drive the thermal mold head 2522 to move along the z-axis to contact the product for heating, and the thermal mold actuator 2521 can drive the thermal mold head 2522 to move in a direction perpendicular to the z-axis to below the clamping structure 2532 in the z-axis direction for heating the workpiece.

[0063] In this embodiment, the driving direction of the first thermal mold driving member 2523 is the z-axis direction, and the driving direction of the second thermal mold driving member 2524 is perpendicular to the z-axis direction. That is, the first thermal mold driving member 2523 can drive the second thermal mold driving member 2524 to move the thermal mold head 2522 along the z-axis direction, and the second thermal mold driving member can drive the thermal mold head 2522 to move in a direction perpendicular to the z-axis direction. In other embodiments, the driving direction of the first thermal mold driving member 2523 can also be perpendicular to the z-axis direction, and the driving direction of the second thermal mold driving member 2524 can also be the z-axis direction.

[0064] In one embodiment of this implementation, please refer to Figure 6 The thermal mold actuator 2521 includes a first slide 2525 and a second slide 2526. The first slide 2525 is slidably engaged with the reference plate 251. A first thermal mold drive component 2523 is connected to the first slide 2525. The second slide 2526 is slidably engaged with the first slide 2525. A second thermal mold drive component 2524 is mounted on the first slide 2525 and connected to the second slide 2526. The thermal mold head 2522 is disposed on the second slide 2526. This configuration enables high-precision movement of the thermal mold head 2522 in both axes.

[0065] In one embodiment of this implementation, please refer to Figure 6 The reference plate 251 and the first slide block 2525 are slidably engaged via guide rails and guide grooves; and / or, the first slide block 2525 and the second slide block 2526 are slidably engaged via guide rails and guide grooves. This arrangement can further improve the movement accuracy of the hot mold head 2522.

[0066] In this embodiment, the reference plate 251 and the first slide block 2525, as well as the first slide block 2525 and the second slide block 2526, are all slidably engaged via guide rails and guide grooves. In other embodiments, the reference plate 251 and the first slide block 2525, as well as the first slide block 2525 and the second slide block 2526, may also employ other sliding engagement methods.

[0067] In one embodiment of this implementation, please refer to Figure 6 and Figure 8 , Figure 8 yes Figure 6 A schematic diagram of the chuck 2534 in the top welding unit 25 is shown. The clamping structure 2532 includes a sliding plate 2533 and a chuck 2534. The sliding plate 2533 slides in engagement with the reference plate 251 and is connected to the welding drive component 2531. The chuck 2534 is detachably mounted on the sliding plate 2533 and is used to clamp and fix the weldment with a matching shape. This arrangement allows for quick disassembly and replacement of the chuck 2534 with a dedicated chuck when processing different products, thereby improving the versatility of welding processing and increasing processing efficiency.

[0068] In this embodiment, the chuck 2534 includes a fixed block 2535, a first quick-release block 2536, a second quick-release block 2537, a rotating block 2538, and a clamping body 2539 connected in sequence. The fixed block 2535 is fixedly connected to the slide plate 2533. The first quick-release block 2536 and the second quick-release block 2537 achieve quick disassembly and installation through a snap-fit ​​connection. The rotating block 2538 and the second quick-release block 2537 have multiple installation positions. The relative angles of the rotating block 2538 and the second quick-release block 2537 around the z-axis differ in different installation positions to simultaneously meet the requirements of avoiding interference and aligning the weldment with the product. The clamping body 2539 has an installation groove whose shape is adapted to the weldment, and the weldment is clamped and fixed within the installation groove. Due to the quick-release connection of the first quick-release block 2536 and the second quick-release block 2537, the dedicated clamping body 2539 can be replaced promptly.

[0069] It is understandable that weldments are typically required to be welded to the surface of a product at a certain angle. The z-axis rotation mechanism 24 can adjust the relative angle between the weldment and the product around the z-axis to align the weldment with the product. It can also swing the top welding unit 25 to avoid interference with adjacent units. In practical use, two situations may arise: when adjusting the weldment to align with the product using the z-axis rotation mechanism 24, the top welding unit 25 may interfere with adjacent units; or when swinging the top welding unit 25 to avoid interference with adjacent units using the z-axis rotation mechanism 24, the weldment may not align with the product. In this embodiment, a rotating block 2538 is provided between the second quick-release block 2537 and the clamping body 2539. Utilizing the multiple mounting positions of the rotating block 2538 and the second quick-release block 2537, the angle of the weldment on the clamping body 2539 around the z-axis is adjusted. This ensures that when the z-axis rotation mechanism 24 adjusts the weldment to align with the product, the top welding unit 25 will not interfere with adjacent units.

[0070] To better address the aforementioned issues, in some embodiments, the clamping structure 2532 includes a rotation adjustment mechanism (not shown) and a camera. Both the rotation adjustment mechanism and the camera are mounted on the slide plate 2533. The rotation adjustment mechanism is connected to the chuck 2534 and is used to drive the chuck 2534 to rotate the weldment relative to the product around the z-axis. 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 based on the image. With this configuration, as long as the z-axis rotation mechanism 24 ensures that the top surface welding unit 25 does not interfere with other adjacent units, the weldment can be adjusted to be aligned with the product by the rotation adjustment mechanism.

[0071] In this embodiment, the x-axis drive member 211, the y-axis drive member 221 and the z-axis drive member 231 are all driven linearly by a lead screw motor, and the first hot mold drive member 2523, the second hot mold drive member 2524 and the welding drive member 2531 are all driven linearly by a cylinder.

[0072] The welding steps of the top surface welding device 200 of the welding equipment 1000 provided in this embodiment are as follows:

[0073] Step 1: The x-axis motion mechanism 21, y-axis motion mechanism 22, z-axis motion mechanism 23 and z-axis rotation mechanism 24 work together to drive the top surface welding unit 25 to move along the x-axis, y-axis and z-axis and rotate around the z-axis, so that the top surface welding unit 25 is in a suitable position (with a certain distance from the adjacent top surface welding unit 25 to ensure that no interference occurs after welding continues).

[0074] Step 2: The second hot mold drive 2524 drives the hot mold head 2522 to move along the direction perpendicular to the z-axis to the bottom side of the clamping structure 2532. At this time, the upper heating surface of the hot mold head 2522 is opposite to the clamping structure 2532, and the lower heating surface of the hot mold head 2522 is opposite to the welding position of the product.

[0075] Step 3: The first hot mold drive component 2523 drives the hot mold head 2522 to move downward along the z-axis, while the welding drive component 2531 drives the clamping structure 2532 to move downward along the z-axis, so that the lower heating surface of the hot mold head 2522 abuts against the welding position of the product, and the upper heating surface of the hot mold head 2522 abuts against the workpiece. The hot mold head 2522 heats both the workpiece and the product at the same time, so that both enter the melting state simultaneously to improve the welding quality.

[0076] Step 4: After the workpiece and the product are heated to the correct position, the first hot mold drive 2523 drives the hot mold head 2522 to move upward along the z-axis, so that the lower heating surface of the hot mold head 2522 is separated from the product. At the same time, the welding drive 2531 drives the clamping structure 2532 to move upward along the z-axis, so that the upper heating surface of the hot mold head 2522 is separated from the workpiece.

[0077] Step 5: The second hot mold drive 2524 drives the hot mold head 2522 to move in a direction perpendicular to the z-axis, so that the hot mold head 2522 leaves the weldment and the product;

[0078] Step 6: The welding drive component 2531 drives the clamping structure 2532 to move the workpiece downward along the z-axis, pressing the workpiece onto the welding position of the product, thereby completing the welding.
