[0002] The oil tank is an important component of vehicles and other transportation tools that use gasoline as a driving energy source. Welding pieces such as fuel nozzles, pipe clamps, carbon tank supports, support blocks, and isolation valve supports are often welded on the oil tank to meet the assembly of peripheral components and the use of the oil tank.

In this way, the top surface welding unit 25 can move along the x-axis direction, the y-axis direction and the z-axis direction, and rotate around the z-axis.

[0048] By setting the x-direction movement mechanism 21, the y-direction movement mechanism 22, the z-direction movement mechanism 23 and the z-axis rotation mechanism 24 between the rack 100 and the top surface welding unit 25, the x-direction movement mechanism 21, the y-direction movement mechanism 22 and the z-direction movement mechanism 23 can drive the z-axis rotation mechanism 24 to move the top surface welding unit 25 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 welding pieces to the welding positions on the top surface of the product, thus adapting to the processing requirements of different products and improving the processing efficiency.

Specifically, in this embodiment, the four top surface welding devices 200 are respectively used to weld the oil nozzle, the support block, the isolation valve support and the pipe clamp to the corresponding welding positions on the top surface of the oil tank product.

[0054] In one embodiment of this embodiment, as shown in Figure 3 , Figure 4 and Figure 7 , Figure 7 is Figure 6Fig. 2 is a schematic view of a part of the z-axis rotating mechanism 24 in the top surface welding device 200 and the structure of the z-direction slide 232. The z-axis rotating mechanism 24 comprises a z-axis rotating driving member 241 and a rotating seat 242. The z-axis rotating driving member 241 is mounted on the z-direction movement mechanism 23, and the rotating seat 242 is mounted on the z-direction movement mechanism 23 in a relative rotating manner about the z-axis. The top surface welding unit 25 is mounted on the rotating seat 242. The z-axis rotating driving member 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. In this way, the z-axis rotating driving member 241 can drive the rotating seat 242 to rotate relative to the z-direction movement mechanism 23 in the form of gear engagement, so as to realize the rotation of the top surface welding unit 25 relative to the rack 100 about the z-axis.

[0055] Specifically, the z-axis rotating driving member 241 is mounted on the z-direction slide 232, and the rotating seat 242 is mounted on the z-direction slide 232 through a bearing, so as to realize the rotation of the rotating seat 242 relative to the z-direction slide 232 about the z-axis.

In this way, the speed reduction transmission can be realized through the cooperation of the first gear 243 and the second gear 244, so as to increase the output torque, and the rotating precision and reliability of the top surface welding unit 25 can be improved.

[0057] In an embodiment of the embodiment, please refer to Figure 4 and Figure 6 , Figure 6 is Figure 4Fig. 2 is a structural schematic view of the top surface welding unit 25 in the top surface welding device 200 of the embodiment.

The fixing assembly 253 is used to fix the welding piece and press the welding piece in the molten state onto the product. In this way, the hot die assembly 252 can heat the welding piece and the product at the same time, which is conducive to improving the welding efficiency. In addition, since the hot die assembly 252 and the fixing assembly 253 are both installed on the reference plate 251, and the reference plate 251 is connected with the z-axis rotating mechanism 24, the z-axis rotating mechanism 24 can drive the reference plate 251 to synchronously rotate around the z-axis with the hot die assembly 252 and the fixing assembly 253, so that the welding piece on the fixing assembly 253 is located above the welding position of the product. The fixing assembly 253 can press the welding piece onto the product. At the same time, under the driving of the z-axis rotating mechanism 24, the hot die assembly 252 and the fixing assembly 253 in the adjacent top surface welding unit 25 are not easy to interfere with each other, so as to realize multi-point synchronous welding and improve the processing efficiency.

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 welding piece, and the lower heating surface is used to heat the product.

[0061] It can be understood that the hot die driving device 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 driving member 2531 can drive the clamping structure 2532 to move the welding piece downward along the z-axis direction, so that the welding piece abuts against the upper heating surface of the hot die head 2522, thereby realizing heating of the welding piece, and the hot die driving device 2521 can also drive the hot die head 2522 to move close to the product, so that the lower heating surface of the hot die head 2522 abuts against the product, thereby realizing heating of the welding piece, thereby realizing automatic heating of the product and the welding piece by the hot die head 2522. At the same time, after the welding piece is heated to a molten state, the hot die driving device 2521 can drive the hot die head 2522 to leave the driving path of the welding driving member 2531 to avoid the clamping structure 2532, and then the welding driving member 2531 drives the clamping structure 2532 to continue moving the welding piece along the z-axis direction, thereby completing automatic welding of the welding piece and the product.

In other embodiments, the driving direction of the first thermal die driving member 2523 can also be a direction perpendicular to the z-axis direction, and the driving direction of the second thermal die driving member 2524 can also be the z-axis direction.

[0064] In one embodiment of this embodiment, referring to Figure 6 , the thermal die driver 2521 includes a first sliding seat 2525 and a second sliding seat 2526, the first sliding seat 2525 is in sliding fit with the reference plate 251, the first thermal die driving member 2523 is connected with the first sliding seat 2525, the second sliding seat 2526 is in sliding fit with the first sliding seat 2525, the second thermal die driving member 2524 is installed on the first sliding seat 2525 and connected with the second sliding seat 2526, and the thermal die head 2522 is arranged on the second sliding seat 2526. In this way, high-precision movement of the thermal die head 2522 in two-axis directions can be achieved.

[0065] In one embodiment of this embodiment, referring to Figure 6 , the reference plate 251 and the first sliding seat 2525 are in sliding fit through guide rails and guide grooves; and / or, the first sliding seat 2525 and the second sliding seat 2526 are in sliding fit through guide rails and guide grooves. In this way, the movement precision of the thermal die head 2522 can be further improved.

[0066] In this embodiment, the reference plate 251 and the first sliding seat 2525, and the first sliding seat 2525 and the second sliding seat 2526 are in sliding fit through guide rails and guide grooves. In other embodiments, the reference plate 251 and the first sliding seat 2525, and the first sliding seat 2525 and the second sliding seat 2526 can also adopt other sliding fit modes.

[0067] In one embodiment of this embodiment, referring to Figure 6 and Figure 8 , Figure 8 is Figure 6 a structural schematic view of a chuck 2534 in the top surface welding unit 25. The clamping structure 2532 includes a sliding plate 2533 and the chuck 2534, the sliding plate 2533 is in sliding fit with the reference plate 251 and connected with a welding driving member 2531, and the chuck 2534 is detachably installed on the sliding plate 2533, and the chuck 2534 is used for clamping and fixing a welding piece with a matched shape. In this way, when different products are processed, the chuck 2534 can be quickly disassembled and replaced with a special chuck 2534, so as to improve the universality of welding processing and improve the processing efficiency.

[0068] In this embodiment, the chuck 2534 comprises 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, wherein the fixed block 2535 is fixedly connected with the sliding plate 2533, the first quick-release block 2536 and the second quick-release block 2537 are connected in a clamping manner to realize quick release and quick installation, the rotating block 2538 has multiple installation positions with the second quick-release block 2537, and the relative angle of the rotating block 2538 and the second quick-release block 2537 around the z-axis is different at different installation positions, so as to simultaneously meet the requirements of avoiding interference and aligning the welding part with the product. The clamping body 2539 is provided with an installation slot, the shape of the installation slot is matched with the welding part, and the welding part is clamped and fixed in the installation slot. Due to the quick-release connection of the first quick-release block 2536 and the second quick-release block 2537, the special clamping body 2539 can be replaced in time.

[0069] It can be understood that the welding part is usually required to be welded to the surface of the product at a certain angle, and the z-axis rotating mechanism 24 can adjust the relative angle of the welding part and the product around the z-axis on one hand to align the welding part with the product, and can swing the top surface welding unit 25 on the other hand to avoid interference with other adjacent units. In actual use, the two situations may be faced, that is, when the welding part is adjusted to align with the product by the z-axis rotating mechanism 24, the top surface welding unit 25 will interfere with other adjacent units, or when the top surface welding unit 25 is swung to avoid interference with other adjacent units by the z-axis rotating mechanism 24, the welding part cannot align with the product. In this embodiment, the rotating block 2538 is arranged between the second quick-release block 2537 and the clamping body 2539, and the rotating block 2538 and the second quick-release block 2537 have multiple installation positions, so as to adjust the angle of the welding part on the clamping body 2539 around the z-axis, so that when the z-axis rotating mechanism 24 adjusts the welding part to align with the product, the top surface welding unit 25 will not interfere with other adjacent units.

[0070] In order to better solve the above problems, in some embodiments, the clamping structure 2532 comprises a rotating adjustment mechanism (not shown) and a camera, both of which are installed on the sliding plate 2533, the rotating adjustment mechanism is connected with the chuck 2534 and is used to drive the chuck 2534 to rotate the welding part relative to the product around the z-axis, and the camera is used to obtain an image of the product, so that the rotating adjustment mechanism can adjust the welding part to align with the product according to the image. In this way, as long as the z-axis rotating mechanism 24 ensures that the top surface welding unit 25 does not interfere with other adjacent units, the welding part can be adjusted to align with the product by the rotating adjustment mechanism.

[0071] In this embodiment, the x-direction driving member 211, the y-direction driving member 221 and the z-direction driving member 231 are all in the form of a screw motor to realize linear driving, the first hot die driving member 2523, the second hot die driving member 2524 and the welding driving member 2531 are all in the form of a cylinder to realize linear driving, and the output push rod (not shown) of the cylinder is connected with the corresponding moving part.

[0072] The welding step of the top surface welding device 200 in the welding equipment 1000 provided by the embodiment is as follows.

[0073] First step: the x-direction motion mechanism 21, the y-direction motion mechanism 22, the z-direction motion mechanism 23 and the z-axis rotation mechanism 24 cooperatively drive the top surface welding unit 25 to move along the x-axis direction, the y-axis direction and the z-axis direction and rotate around the z-axis, so that the top surface welding unit 25 is in a suitable position (with a certain interval distance from the adjacent top surface welding unit 25 to ensure that interference does not occur after welding continues);

[0074] Second step: the second hot die driving member 2524 drives the hot die head 2522 to move along a direction perpendicular to the z-axis direction to the bottom side of the clamping structure 2532, at this time, the upper heating surface of the hot die head 2522 is opposite to the clamping structure 2532, and the lower heating surface of the hot die head 2522 is opposite to the welding position of the product;

[0075] Third step: the first hot die driving member 2523 drives the hot die head 2522 to move downward along the z-axis direction, and 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 welding piece, the hot die head 2522 simultaneously heats the welding piece and the product, so that both of them synchronously enter a molten state to improve the welding quality;

[0076] Fourth step: after the welding piece and the product are heated in place, the first hot die driving member 2523 drives the hot die head 2522 to move upward along the z-axis direction, so that the lower heating surface of the hot die head 2522 is separated from the product, and the welding driving member 2531 drives the clamping structure 2532 to move upward along the z-axis direction, so that the upper heating surface of the hot die head 2522 is separated from the welding piece;

[0077] Fifth step: the second hot die driving member 2524 drives the hot die head 2522 to move along a direction perpendicular to the z-axis direction, so that the hot die head 2522 is separated from the welding piece and the product;

[0078] Sixth step: the welding driving member 2531 drives the clamping structure 2532 to move the welding piece downward along the z-axis direction, so that the welding piece is pressed to the welding position of the product, thereby completing the welding.
