Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of automobile manufacturing technology, and in particular, to a welding device for processing a chassis of a new energy pickup truck. Background Art

[0002] In the manufacturing process of new energy pickup trucks, the chassis is the key load-bearing component of the vehicle, and its welding quality is directly related to the safety, stability and overall performance of the vehicle. With the rapid development of the new energy vehicle industry, more stringent requirements are placed on the welding accuracy, efficiency and reliability of the chassis.

[0003] At present, in the welding process of automobile chassis, in order to ensure the welding quality, the weld needs to be pre-cleaned before welding to remove surface oil, impurities, oxide layer, etc. In the prior art, the cleaning device matched with the welding gun mostly adopts a fixed structure or moves synchronously with the welding gun through an additional drive unit. The cleaning path of these cleaning devices is often pre-set and difficult to change, and cannot be flexibly adjusted according to the complex and changeable shape and weld direction of the chassis of new energy pickup trucks. When facing irregular welds or parts with special curvature on the chassis, the fixed cleaning path makes it impossible to effectively cover some weld areas, resulting in incomplete cleaning. This makes it very easy to cause welding defects such as pores and cracks in some weld areas due to incomplete cleaning in actual operation, and the residual impurities and contaminants during the welding process will seriously affect the strength and reliability of the welded joints. Not only does it reduce the overall quality of the automobile chassis, but it also increases the scrap rate in the production process, increases production costs, and also poses a potential threat to the driving safety of new energy pickup trucks.

Specific embodiments

[0043] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present disclosure and not for limiting the present disclosure.

[0044] For the sake of simplicity of the drawings, only the parts related to the disclosure are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, parts with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also means "more than one" situation, and "several" includes "two" and "more than two".

[0045] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0046] In the present disclosure, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact of the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or only indicating that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below" and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or only indicating that the first feature is at a lower horizontal height than the second feature.

[0047] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", and "right" are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present disclosure.

[0048] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0049] As Figures 1 to 2 shown, it shows a welding device in an embodiment of the present disclosure. A slewing bearing structure is adopted between the manipulator 8 and the housing 1 to achieve rotational connection, enabling the housing 1 to rotate at the end of the manipulator 8 to achieve omnidirectional angle adjustment, facilitating the positioning of the welding torch 2 and the cleaning device 3. The housing 1 is designed as a frame structure, and a linear guide rail is installed on one side thereof. The sliding carriage 31 cooperates with this linear guide rail and can slide linearly along the guide rail.

[0050] The clamping jaw 32 can be a pneumatic clamping jaw, which is installed at one end of the sliding carriage 31 away from the manipulator 8. The pneumatic clamping jaw 32 includes a cylinder block, a piston, and four clamping portions 321. The cylinder block is fixed on the sliding carriage 31. When compressed air is introduced into the cylinder block, under the action of air pressure, it drives the four clamping portions 321 to perform linear sliding in opposite or away directions, thereby realizing the clamping and releasing actions of the cleaning cloth 5. The four clamping portions 321 are symmetrically distributed in pairs of two, and anti-slip stripes are provided on the opposite inner sides. When clamping the cleaning cloth 5, the anti-slip stripes can increase the friction with the cleaning cloth 5 to ensure that the cleaning cloth 5 is firmly clamped.

[0051] During operation, the manipulator 8 drives the housing 1 to move to the vicinity of the welding point on the chassis of the new energy pickup truck according to a preset program. Then, the sliding carriage 31 slides on the linear guide rail, causing the pneumatic clamping jaw 32 to move to the side away from the manipulator 8 until it presses against the chassis. At this time, the cleaning cloth 5 comes into contact with the chassis surface and starts to clean the impurities and oil stains at the welding point. As the manipulator 8 further moves, the sliding carriage 31 continuously slides on the linear guide rail to adapt to the shape change of the chassis, ensuring that the cleaning cloth 5 always fits tightly against the chassis surface to complete the cleaning of the entire welding area to be cleaned. After the welding is completed with the movement of the manipulator 8, the sliding carriage 31 retracts to the initial position, stops supplying air to the cylinder block, and the piston drives the four clamping portions 321 to move away from each other to release the cleaning cloth 5.

[0052] Through the rotational connection between the robotic arm 8 and the housing 1 and the linear sliding structure of the sliding carriage 31, the cleaning device 3 can well adapt to the shape and structure of the new energy pickup truck chassis. The clamping jaw 32 can clamp and release the cleaning cloth 5 through the pneumatic drive of four clamping parts 321, ensuring the efficient progress of the cleaning work. It effectively solves the problem in the prior art that the weld cleaning device on one side of the welding torch 2 of the vehicle chassis cannot always fit the vehicle chassis, resulting in incomplete pre-cleaning of the welds, improves the cleaning effect before welding, and further improves the welding quality and firmness.

[0053] As Figures 1 to 2 shown, in this embodiment, the first elastic member 4 is a spring, one end of which is fixed on the housing 1 and the other end is connected to the sliding carriage 31. The spring is in a pre-compressed state, providing a continuous elastic pushing force towards the chassis direction for the sliding carriage 31.

[0054] During operation, when the robotic arm 8 drives the housing 1 close to the chassis and the sliding carriage 31 slides on the linear guide rail and presses against the chassis, the first elastic member 4 will be further compressed or elongated according to the undulation of the chassis surface and the change of the pressing force. For example, when encountering a convex part on the chassis surface, the sliding carriage 31 receives a greater resistance, and the first elastic member 4 is further compressed to buffer the pressing force.

[0055] The first elastic member 4 works in coordination with the robotic arm 8, the sliding carriage 31 and the clamping jaw 32. The robotic arm 8 is responsible for moving the cleaning device 3 to the area to be cleaned, the sliding carriage 31 realizes the position adjustment of the cleaning device 3 on the housing 1, and the clamping jaw 32 is used to clamp the cleaning cloth 5. The elastic pushing action of the first elastic member 4 reduces the dependence on the positioning accuracy of the robotic arm 8 and the sliding carriage 31 when the cleaning device 3 adapts to the uneven chassis surface, and reduces the problem of incomplete cleaning caused by positioning errors.

[0056] As Figures 2 to 3 shown, the swinging member 33 is swing-connected to the sliding carriage 31 through a pin shaft, and the clamping jaw 32 is installed at the outer end of the swinging member 33. The cleaning cloth storage bin 6 is slidably connected to the housing 1 through a guide rail, and the cleaning cloth storage bin 6 has a cleaning cloth outlet 61 facing the sliding carriage 31.

[0057] When it is necessary to replace the cleaning cloth 5, the swinging member 33 swings close to the cleaning cloth outlet 61 driven by a power mechanism (such as a gear-rack mechanism driven by a small motor), and at the same time the cleaning cloth storage bin 6 slides close to the clamping jaw 32 driven by another power mechanism (such as an electric push rod). When the clamping jaw 32 approaches the cleaning cloth 5 at the cleaning cloth outlet 61, the pneumatic clamping jaw 32 acts, and the four clamping parts 321 approach each other, press against and clamp the cleaning cloth 5. Then, the swinging member 33 swings back to the initial position to prepare for the cleaning work.

[0058] The cooperation among the swinging member 33, the towel storage bin 6, and the clamping jaw 32 realizes the automatic clamping function of the cleaning towel 5. The swinging of the swinging member 33 expands the movement range of the clamping jaw 32, enabling the clamping jaw 32 to accurately reach the towel outlet 61 of the towel storage bin 6. The sliding function of the towel storage bin 6 ensures that the towel outlet 61 can approach the clamping jaw 32, facilitating the clamping operation. This structure reduces manual intervention, improves the efficiency of replacing the cleaning towel 5, and thus enhances the automation level of the entire welding equipment. At the same time, the automatic clamping process reduces the contamination and damage to the cleaning towel 5 during clamping, ensuring the cleanliness and usability of the cleaning towel 5, which is beneficial to improving the cleaning effect.

[0059] As Figures 3 to 4 shown, the sliding frame 31 has a limiting cavity 311 with an opening 312 facing away from the manipulator 8. A sliding member 34 is arranged in the limiting cavity 311. The sliding member 34 is in cooperation with the limiting cavity 311 through a guide rail and can slide in the limiting cavity 311. The swinging member 33 is swingably arranged at one end of the sliding member 34 away from the manipulator 8.

[0060] Before the cleaning work starts, the sliding member 34 is outside the limiting cavity 311, and the swinging member 33 can swing freely. After the swinging member 33 clamps the cleaning towel 5 and returns to the working position, the sliding member 34 is driven by a power mechanism (such as a push rod driven by an electromagnet) to slide along the guide rail of the limiting cavity 311, driving the swinging member 33 into the limiting cavity 311. At this time, the inner wall of the limiting cavity 311 restricts the circumferential swinging of the swinging member 33, keeping the swinging member 33 stable during the cleaning process.

[0061] The mutual cooperation among the limiting cavity 311, the sliding member 34, and the swinging member 33 improves the stability of the cleaning process. The limiting cavity 311 provides a stable working environment for the swinging member 33, reducing the interference of external factors on the swinging member 33. The sliding function of the sliding member 34 realizes the flexible switching of the swinging member 33 between the working and non-working states. During the cleaning process, the stable state of the swinging member 33 ensures the position accuracy of the clamping jaw 32 and the cleaning towel 5, enabling the cleaning towel 5 to accurately act on the welding point to be welded, improving the cleaning accuracy and effect.

[0062] As Figures 3 to 4 shown, the mounting plate 35 is fixed on one side of the sliding frame 31. A telescopic member 36 (such as an electric telescopic rod) is mounted on the mounting plate 35, and its telescopic direction is perpendicular to the sliding direction of the sliding member 34.

[0063] After the sliding member 34 slides to drive the swinging member 33 out of the limiting cavity 311, the telescopic member 36 is activated, and its extending end gradually extends and abuts against the side wall of the swinging member 33. As the extending end continues to extend, it pushes the swinging member 33 to swing around the pin shaft, adjusting the clamping jaw 32 to an appropriate angle.

[0064] The telescopic member 36 works in coordination with the sliding member 34, the swinging member 33 and the clamping jaw 32, thus enhancing the adaptability of the device. The sliding of the sliding member 34 enables the swinging member 33 to enter or leave the limiting cavity 311, thus providing a prerequisite for the telescopic member 36 to adjust the angle of the swinging member 33. The telescopic function of the telescopic member 36 can adjust the angle of the swinging member 33 and the clamping jaw 32 according to the different shapes and positions of the chassis welding points. The flexible adjustment of the angle of the clamping jaw 32 enables the cleaning towel 5 to better fit the chassis surface, thus expanding the scope of application of the cleaning device 3 and improving the comprehensiveness and effectiveness of the cleaning. At the same time, this angle adjustment reduces unnecessary cleaning actions and improves the cleaning efficiency.

[0065] like Figures 4 to 6 As shown, an abutment plate 37 is installed at the outer end of each clamping portion 321 , and a plurality of anti-slip protrusions 371 are distributed on the outer end surface of the abutment plate 37 .

[0066] When the four clamping parts 321 of the pneumatic clamping jaws 32 approach each other to clamp the cleaning towel 5, the abutment plate 37 first contacts the cleaning towel 5. As the clamping parts 321 continue to approach, the anti-slip protrusions 371 increase the friction with the cleaning towel 5. At the same time, as the four abutment plates 37 gradually approach each other, the cleaning towel 5 is squeezed in the clamping space 322, resulting in wrinkles.

[0067] The abutment plate 37 increases the contact area with the cleaning towel 5, and the anti-skid protrusion 371 further enhances the friction force, ensuring that the cleaning towel 5 does not slide during the clamping process, so that the cleaning towel 5 can more effectively absorb and remove impurities and oil stains at the welding points of the chassis during the cleaning process.

[0068] like Figures 4 to 6 As shown, the abutment disc 37 is provided with a bite tooth 372 near one side of the clamping space 322. When the four clamping parts 321 drive the abutment disc 37 to approach each other to clamp the cleaning towel 5, the bite teeth 372 gradually bite each other.

[0069] The bite teeth 372 work together with the abutment plate 37 and the clamping jaws 32 to enhance the clamping stability of the cleaning towel 5. The abutment plate 37 provides a mounting base for the bite teeth 372, and the clamping action of the clamping jaws 32 drives the abutment plate 37 and the bite teeth 372 to approach each other. The mutual bite of the bite teeth 372 further enhances the fixing ability of the cleaning towel 5, ensuring that the cleaning towel 5 is always firmly fixed on the clamping jaws 32 during the entire cleaning process. This reduces the cleaning interruption and incomplete cleaning problems caused by the falling off or displacement of the cleaning towel 5, and improves the continuity and reliability of the cleaning work.

[0070] like Figures 4 to 6As shown, the outer end surface of the abutment disk 37 is provided with an anti-slip hook 373, and the anti-slip hook 373 is adjacent to the anti-slip protrusion 371. When the abutment disk 37 abuts against the cleaning towel 5, the anti-slip hook 373 will be embedded in the fiber of the cleaning towel 5. The abutment disk 37 provides an installation position for the anti-slip hook 373, and the anti-slip protrusion 371 increases the friction between the abutment disk 37 and the cleaning towel 5. The clamping action of the clamping claw 32 makes the abutment disk 37 and the anti-slip hook 373 closely contact the cleaning towel 5. The hooking action of the anti-slip hook 373 further enhances the fixing effect of the cleaning towel 5 and reduces the risk of the cleaning towel 5 falling off. This ensures the continuity and stability of the cleaning work, avoids the operation of re-clamping the cleaning towel 5 due to the falling off of the cleaning towel 5, and improves the work efficiency.

[0071] like Figures 2 to 4 As shown, the towel-removing rod 7 is hinged to the side of the towel storage bin 6 away from the manipulator 8 through a pin, and a torsion spring is installed at the hinge of the towel-removing rod 7. The torsion spring is in a pre-stretched state, providing an elastic pulling force for the towel-removing rod 7 to rotate in the direction of the clamp 32.

[0072] When the cleaning work is completed, the four clamping parts 321 of the pneumatic clamping jaws 32 move away from each other, releasing the cleaning towel 5. At this time, the swinging member 33 drives the clamping jaws 32 to swing, and the towel stripping rod 7 rotates close to the clamping jaws 32 under the tension of the torsion spring. When the towel stripping rod 7 passes through the clamping space 322, it will block the cleaning towel 5 and make the cleaning towel 5 separate from the abutment plate 37.

[0073] The towel-removing rod 7, the torsion spring, the swinging member 33 and the clamping claw 32 cooperate with each other to realize the automatic disengagement function of the cleaning towel 5. The swinging member 33 drives the clamping claw 32 to swing, providing an opportunity for the towel-removing rod 7 to contact the cleaning towel 5. The torsion spring provides the power for the towel-removing rod 7 to rotate, so that the towel-removing rod 7 can rotate to a suitable position in time to block the cleaning towel 5. This automatic disengagement function reduces manual intervention and improves the efficiency of replacing the cleaning towel 5. At the same time, it avoids the pollution and damage to the cleaning device that may be caused when the cleaning towel 5 is manually removed, ensuring the cleanliness and reliability of the cleaning device.

[0074] like Figures 2 to 4 As shown, the interior of the storage body 62 of the towel storage bin 6 is used to store the cleaning towel 5, and the towel outlet 61 is located on the side of the storage body 62 close to the sliding frame 31. The pressing plate 63 is slidably arranged in the storage body 62 through the guide rail, and the second elastic member 64 (such as a spring) is arranged in the storage body 62, one end of which is connected to the pressing plate 63, and the other end is connected to the inner wall of the storage body 62. The second elastic member 64 is in a pre-compressed state, providing an elastic push force for the pressing plate 63 toward the towel outlet 61.

[0075] When storing the cleaning towel 5 in the towel storage bin 6, the cleaning towel 5 is placed into the bin body 62. Under the action of the second elastic member 64, the pressing plate 63 slides towards the towel outlet 61, and always presses the cleaning towel 5 towards the towel outlet 61. When the clamping jaw 32 approaches the towel outlet 61 to clamp the cleaning towel 5, due to the pushing action of the pressing plate 63, the cleaning towel 5 can be stably located at the position of the towel outlet 61, facilitating clamping.

[0076] The bin body 62, the pressing plate 63 and the second elastic member 64 work together to ensure the stability of the supply of the cleaning towel 5. The bin body 62 provides a storage space for the cleaning towel 5, and the pressing plate 63 applies a pushing force to the cleaning towel 5 under the action of the second elastic member 64. This structure ensures that no matter how many cleaning towels 5 are in the bin body 62, the cleaning towels 5 can always be near the towel outlet 61, facilitating clamping by the clamping jaw 32.

[0077] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
