Description

Technical Field

[0001] The present invention relates to the technical field of welding, in particular to a welding device. Background Art

[0002] Fuel tanks are essential components for gasoline-powered vehicles, such as automobiles. Fuel tanks typically require welding of components such as nozzles, pipe clamps, carbon canister brackets, support blocks, and isolation valve brackets to ensure proper assembly of surrounding components and ensure proper operation.

[0003] In the prior art, dedicated welding equipment is usually equipped to meet the processing requirements of different fuel tank top surfaces. Each welding unit in the welding equipment corresponds to multiple welding positions on the fuel tank top surface, and the welding unit welds the weldment to the welding position to complete the welding process of the fuel tank. This requires workers to adjust the positions of each welding unit to meet the processing requirements of different fuel tanks when faced with different fuel tanks, which reduces processing efficiency. Moreover, because the welding unit occupies a large space, when faced with a scene where multiple welding positions are densely arranged on some fuel tanks, multiple welding positions can only be welded sequentially (for example, after welding position 1, the welding unit needs to be adjusted to face position 2, and then weld position 2, and so on), further reducing processing efficiency.

An embodiment of the present invention provides a welding device 1000, which includes a frame 100 and a plurality of top surface welding devices 200. A plurality of top surface welding devices 200 are installed on the frame 100. Each top surface welding device 200 includes an x-axis motion mechanism 21, a y-axis motion mechanism 22, a z-axis motion mechanism 23, a z-axis rotation mechanism 24 and a top surface welding unit 25 connected in sequence, the x-axis motion mechanism 21, the y-axis motion mechanism 22 and the z-axis motion mechanism 23 are used to cooperate with the driving z-axis rotation mechanism 24 to drive the top surface welding unit 25 to move along the x-axis direction, the y-axis direction and the z-axis direction, the z-axis rotation mechanism 24 is used to drive the top surface welding unit 25 to rotate around the z-axis, and the top surface welding unit 25 is used to weld the weldment to the top surface of the product.

[0029] Specifically, the frame 100 is constructed from multiple welded metal pipes. Multiple top welding devices 200 are hoisted from the top of the frame 100, facilitating welding of products placed within the frame 100. The welding equipment 1000 also includes a side welding device 300, a back welding device 400, a workbench 500, a transfer station 600, and a feed station 700. Both the side welding device 300 and the back welding device 400 are mounted at the bottom of the frame 100, facilitating welding of the product sides by the side welding device 300 and the back welding device 400 on the back.

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.

[0030] It can be understood that the x-axis motion mechanism 21 is mounted on the frame 100 and can drive the y-axis motion mechanism 22 to drive the z-axis motion mechanism 23, the z-axis rotation mechanism 24 and the top surface welding unit 25 to move 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 drive the z-axis rotation mechanism 24 and the top surface welding unit 25 to move 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 drive the top surface welding unit 25 to move 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 about the z-axis relative to the z-axis motion mechanism 23. In this way, the top surface welding unit 25 can move along the x-axis, y-axis and z-axis directions, and rotate about the z-axis.

[0031] By arranging an x-axis motion mechanism 21, a y-axis motion mechanism 22, a z-axis motion mechanism 23 and a z-axis rotation mechanism 24 between the frame 100 and the top surface welding unit 25, the x-axis motion mechanism 21, the y-axis motion mechanism 22 and the z-axis motion mechanism 23 can cooperate with the driving z-axis rotation mechanism 24 to drive the top surface welding unit 25 to move along the x-axis direction, the y-axis direction and the z-axis direction, so that the top surface welding unit 25 can weld the weldment to the welding position on the top surface of the product, thereby adapting to the processing requirements of different products and improving the processing efficiency. At the same time, the z-axis rotation mechanism 24 can drive the top surface welding unit 25 to rotate around the z-axis. When welding the top surface of the product, the top surface welding units 25 in multiple top surface welding devices 200 can avoid each other to avoid interference, so that multiple welding positions densely arranged on the top surface of the product can be welded at the same time, further improving the processing efficiency.

[0032] In one embodiment of this embodiment, please refer to Figure 3 and Figure 4 The frame 100 is provided with an x-axis slide 101. The x-axis motion mechanism 21 includes an x-axis drive member 211 and an x-axis slide 212. The x-axis slide 212 slidably engages with the x-axis slide 101. The x-axis drive member 211 is mounted on the frame 100 and connected to the x-axis slide 212. The y-axis motion mechanism 22 is mounted on the x-axis slide 212. This arrangement enables high-precision movement of the top surface welding unit 25 relative to the frame 100 in the x-axis direction.

[0033] In one embodiment of this embodiment, please refer to Figures 3 to 5 , Figure 5 yes Figure 4 Schematic diagram of the structure of the top surface welding device 200 and the x-direction slide 101 from another perspective. The welding equipment 1000 includes multiple groups of top surface welding devices 200, with at least two top surface welding devices 200 in each group, and multiple x-direction slides 101, which are arranged in sequence along the y-axis direction, and the x-direction slides 212 in the top surface welding devices 200 of each group slide in conjunction with the same x-direction slide 101. With such an arrangement, the x-direction slides 212 of the top surface welding devices 200 of each group can move along the same x-direction slide 101, which on the one hand simplifies the structure and reduces the cost, and on the other hand improves the position accuracy of the top surface welding units 25 in the same group and reduces the risk of interference.

[0034] In this embodiment, the welding equipment 1000 includes two groups of top surface welding devices 200, and the number of top surface welding devices 200 in each group is two, that is, a total of four top surface welding devices 200. Two x-direction slide rails 101 are provided on the frame 100, and the two x-direction slide rails 101 are spaced apart along the y-axis direction. The two groups of top surface welding devices 200 are slidably matched with the corresponding x-direction slide rails 101 respectively. With such an arrangement, the four top surface welding devices 200 can simultaneously perform welding processing on the top surface of the product. Specifically, in this embodiment, the four top surface welding devices 200 are respectively used to weld the oil nozzle, support block, isolation valve bracket and pipe clamp to the corresponding welding positions on the top surface of the oil tank product.

[0035] In one embodiment of this embodiment, 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 222. The x-axis slide 212 is provided with a y-axis slide rail 213. The y-axis slide 222 slidably engages with the y-axis slide rail 213. The y-axis drive member 221 is mounted on the x-axis slide 212 and connected to the y-axis slide 222. The z-axis motion mechanism 23 is mounted on the y-axis slide 222. This arrangement enables high-precision movement of the top surface welding unit 25 relative to the frame 100 in the y-axis direction.

[0036] In one embodiment of this embodiment, 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 232. The y-axis slide 222 is provided with a z-axis slide rail 223. The z-axis slide 232 slidably engages with the z-axis slide rail 223. The z-axis drive member 231 is mounted on the y-axis slide 222 and connected to the z-axis slide 232. The z-axis rotation mechanism 24 is mounted on the z-axis slide 232. This arrangement enables high-precision movement of the top surface welding unit 25 relative to the frame 100 in the z-axis direction.

[0037] In one embodiment of this embodiment, please refer to Figure 3 、 Figure 4 and Figure 7 , Figure 7 yes Figure 6Schematic diagram of the partial structure of the z-axis rotation mechanism 24 and the structure of the z-direction slide 232 in the top surface welding device 200. The z-axis rotation mechanism 24 includes a z-axis rotation driver 241 and a rotating seat 242. The z-axis rotation driver 241 is installed on the z-direction motion mechanism 23. The rotating seat 242 can be installed on the z-direction motion mechanism 23 so as to rotate relative to the z-axis. The top surface welding unit 25 is installed on the rotating seat 242. The z-axis rotation driver 241 is provided with a first gear 243, and the rotating seat 242 is provided with a second gear 244. The first gear 243 and the second gear 244 are engaged. With such an arrangement, the z-axis rotation driver 241 can drive the rotating seat 242 to rotate relative to the z-direction motion mechanism 23 in the form of gear engagement, so as to realize the rotation of the top surface welding unit 25 relative to the frame 100 around the z-axis.

[0038] Specifically, the z-axis rotation driver 241 is mounted on the z-direction slide 232, and the rotating base 242 is mounted on the z-direction slide 232 via a bearing, so that the rotating base 242 can rotate around the z-axis relative to the z-direction slide 232. The rotating base 242 is inserted into the z-direction slide 232, and a second gear 244 is provided at the bottom end.

[0039] In one embodiment of this embodiment, please refer to Figure 4 and Figure 7 The number of teeth of the first gear 243 is smaller than the number of teeth of the second gear 244. In this way, the first gear 243 and the second gear 244 can cooperate to achieve a reduction transmission to increase the output torque, thereby improving the rotation accuracy and reliability of the top surface welding unit 25.

[0040] In one embodiment of this embodiment, please refer to Figure 4 and Figure 6 , Figure 6 yes Figure 4A schematic diagram of the structure of the top surface welding unit 25 in the top surface welding device 200. The top surface welding unit 25 includes a reference plate 251, a hot mold assembly 252, and a fixed assembly 253. The reference plate 251 is connected to the z-axis rotation mechanism 24. The hot mold assembly 252 and the fixed assembly 253 are both mounted on the reference plate 251. The hot mold assembly 252 is used to heat the weldment and the product to a molten state, and the fixed assembly 253 is used to fix the weldment and press the molten weldment onto the product. This arrangement allows the hot mold assembly 252 to heat the weldment and the product simultaneously, which helps improve welding efficiency. In addition, since the hot mold assembly 252 and the fixed assembly 253 are both installed on the reference plate 251, the reference plate 251 is connected to the z-axis rotation mechanism 24, so that 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, so that the weldment on the fixed assembly 253 is located 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 the adjacent top surface welding unit 25 are not prone to interference, so as to achieve multi-point synchronous welding and improve processing efficiency.

[0041] In this embodiment, the reference plate 251 is fixedly connected to the rotating base 242 , so that under the drive of the z-axis rotation driving member 241 , the rotating base 242 can drive the reference plate 251 to rotate synchronously.

[0042] In one embodiment of this embodiment, please refer to Figure 4 and Figure 6 The hot mold assembly 252 and the fixing assembly 253 are respectively installed on the opposite sides of the reference plate 251. Such an arrangement has a simpler structure and can reduce the space occupied by the top surface welding unit 25.

[0043] In one embodiment of this embodiment, please refer to Figure 4 and Figure 6The fixing assembly 253 includes a welding drive 2531 and a clamping structure 2532 for clamping the weldment. The welding drive 2531 is installed on the reference plate 251 and is 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 installed on the reference plate 251 and is 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 weldment in the z-axis direction, and the hot mold driver 2521 is also used to drive the hot mold head 2522 to move to abut against the product, and the welding drive 2531 is used to drive the clamping structure 2532 to drive the weldment to move along the z-axis direction, so that the weldment 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 weldment, and the lower heating surface is used to heat the product.

[0044] It is understood that the hot die driver 2521 drives the hot die head 2522 to move to the bottom side of the clamping structure 2532 in the z-axis direction. At this time, the welding driver 2531 can drive the clamping structure 2532 to drive the weldment to move downward along the z-axis, so that the weldment abuts the upper heating surface of the hot die head 2522, thereby heating the weldment. In addition, the hot die driver 2521 can also drive the hot die head 2522 to move closer to the product, so that the lower heating surface of the hot die head 2522 abuts the product, thereby heating the weldment, thereby achieving automated heating of the product and the weldment by the hot die head 2522. At the same time, after the weldment is heated to a molten state, the hot die driver 2521 can drive the hot die head 2522 to leave the driving path of the welding driver 2531 to avoid the clamping structure 2532. The welding driver 2531 then drives the clamping structure 2532 to drive the weldment to continue moving along the z-axis, completing the automated welding of the weldment and the product.

[0045] In one embodiment of this embodiment, please refer to Figure 6 The hot die driver 2521 includes a first hot die driver 2523 and a second hot die driver 2524. The first hot die driver 2523 is mounted on the reference plate 251 and connected to the second hot die driver 2524. The hot die head 2522 is disposed on the second hot die driver 2524. The first hot die driver 2523 and the second hot die driver 2524 cooperate to drive the hot die head 2522 to move along the z-axis and in a direction perpendicular to the z-axis. With this arrangement, the hot die driver 2521 can drive the hot die head 2522 to move along the z-axis until it contacts the product to heat it. Furthermore, the hot die driver 2521 can drive the hot die head 2522 to move along the z-axis perpendicular to the z-axis to below the clamping structure 2532 in the z-axis direction to heat the weldment.

[0046] In this embodiment, the driving direction of the first hot mold driver 2523 is the z-axis direction, and the driving direction of the second hot mold driver 2524 is a direction perpendicular to the z-axis direction. That is, the first hot mold driver 2523 can drive the second hot mold driver 2524 to drive the hot mold head 2522 to move along the z-axis direction, and the second hot mold driver can drive the hot mold head 2522 to move in a direction perpendicular to the z-axis direction. In other embodiments, the driving direction of the first hot mold driver 2523 can also be a direction perpendicular to the z-axis direction, and the driving direction of the second hot mold driver 2524 can also be the z-axis direction.

[0047] In one embodiment of this embodiment, please refer to Figure 6 The hot mold driver 2521 includes a first slide 2525 and a second slide 2526. The first slide 2525 is in sliding engagement with the reference plate 251. The first hot mold driver 2523 is connected to the first slide 2525. The second slide 2526 is in sliding engagement with the first slide 2525. The second hot mold driver 2524 is mounted on the first slide 2525 and connected to the second slide 2526. The hot mold head 2522 is disposed on the second slide 2526. This arrangement enables high-precision movement of the hot mold head 2522 in both directions.

[0048] In one embodiment of this embodiment, please refer to Figure 6 The reference plate 251 and the first slide 2525 are slidably engaged with each other via guide rails and guide grooves; and / or the first slide 2525 and the second slide 2526 are slidably engaged with each other via guide rails and guide grooves. This arrangement can further improve the movement accuracy of the hot die head 2522.

[0049] In this embodiment, the reference plate 251 and the first slide 2525, as well as the first slide 2525 and the second slide 2526 are all slidably matched by guide rails and guide grooves. In other embodiments, the reference plate 251 and the first slide 2525, as well as the first slide 2525 and the second slide 2526 can also adopt other sliding matching methods.

[0050] In one embodiment of this embodiment, please refer to Figure 6 and Figure 8 , Figure 8 yes Figure 6 A schematic diagram of the structure of the chuck 2534 in the top surface welding unit 25 is shown. The clamping structure 2532 includes a slide 2533 and a chuck 2534. The slide 2533 slidably engages with the reference plate 251 and is connected to the welding driver 2531. The chuck 2534 is detachably mounted on the slide 2533 and is used to clamp and secure a weldment of matching shape. This arrangement allows for quick removal and replacement of the chuck 2534 for different product processing, improving the versatility and efficiency of the welding process.

[0051] 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, which are connected in sequence. The fixed block 2535 is fixedly connected to the slide 2533. The first and second quick-release blocks 2536 and 2537 are fastened together to enable quick removal and installation. The rotating block 2538 and the second quick-release block 2537 have multiple mounting positions. The relative angles of the rotating block 2538 and the second quick-release block 2537 about the z-axis vary in different mounting positions, thereby simultaneously meeting the requirements of avoiding interference and aligning the weldment with the product. The clamping body 2539 defines a mounting slot whose shape is adapted to the weldment, and the weldment is clamped and fixed within the mounting slot. The quick-release connection of the first and second quick-release blocks 2536 and 2537 allows the dedicated clamping body 2539 to be replaced promptly.

[0052] It is understood 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 about the z-axis to align the weldment with the product, and can also swing the top surface welding unit 25 to avoid interference with other adjacent units. In actual use, two situations may arise: when the z-axis rotation mechanism 24 is used to adjust the weldment to align with the product, the top surface welding unit 25 may interfere with other adjacent units, or when the z-axis rotation mechanism 24 is used to swing the top surface welding unit 25 to avoid interference with other adjacent units, the weldment cannot be aligned with the product. In this embodiment, a rotating block 2538 is provided between the second quick-release block 2537 and the clamping body 2539. The rotating block 2538 and the second quick-release block 2537 have multiple mounting positions to adjust the angle of the weldment on the clamping body 2539 about the z-axis. This allows the top surface welding unit 25 to avoid interference with other adjacent units when the z-axis rotation mechanism 24 adjusts the weldment to align with the product.

[0053] To better address the aforementioned issues, in some embodiments, the clamping structure 2532 includes a rotational adjustment mechanism (not shown) and a camera, both mounted on a slide 2533. The rotational adjustment mechanism is connected to the chuck 2534 and is used to drive the chuck 2534 to rotate the weldment relative to the product about the z-axis. The camera is used to capture an image of the product so that the rotational adjustment mechanism can adjust the weldment to align with the product based on the image. With this arrangement, 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 rotational adjustment mechanism can be used to adjust the weldment to align with the product.

[0054] In this embodiment, the x-direction driving member 211, the y-direction driving member 221 and the z-direction driving member 231 all use screw motors to achieve linear drive, and the first hot mold driving member 2523, the second hot mold driving member 2524 and the welding driving member 2531 all use cylinders to achieve linear drive, and the output push rod of the cylinder (not shown) is connected to the corresponding moving parts.

[0055] The welding steps of the top surface welding device 200 in the welding equipment 1000 provided in this embodiment are as follows: Step 1: The x-axis motion mechanism 21, the y-axis motion mechanism 22, the z-axis motion mechanism 23, and the z-axis rotation mechanism 24 cooperate to drive the top surface welding unit 25 to move along the x-axis, y-axis, and z-axis directions, and to 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 there is no interference after welding continues); Step 2: The second hot die driving member 2524 drives the hot die head 2522 to move in a 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 die head 2522 faces the clamping structure 2532, and the lower heating surface of the hot die head 2522 faces the welding position of the product. Step 3: The first hot die driving member 2523 drives the hot die head 2522 to move downward along the z-axis direction. At the same time, the welding driving member 2531 drives the clamping structure 2532 to move downward along the z-axis direction, so that the lower heating surface of the hot die head 2522 abuts against the welding position of the product, and the upper heating surface of the hot die head 2522 abuts against the weldment. The hot die head 2522 heats the weldment and the product at the same time, so that both enter a molten state synchronously, thereby improving the welding quality. Step 4: After the weldment and the product are heated to the desired position, the first heat mold driving member 2523 drives the heat mold head 2522 to move upward along the z-axis, so that the lower heating surface of the heat mold head 2522 is separated from the product. At the same time, the welding driving member 2531 drives the clamping structure 2532 to move upward along the z-axis, so that the upper heating surface of the heat mold head 2522 is separated from the weldment. Step 5: The second hot die driving member 2524 drives the hot die head 2522 to move in a direction perpendicular to the z-axis direction, so that the hot die head 2522 moves away from between the weldment and the product; Step 6: The welding driver 2531 drives the clamping structure 2532 to move the weldment downward along the z-axis direction, pressing the weldment to the welding position of the product, thereby completing the welding.
