[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0037] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0038] Currently, in existing technologies, traditional welding methods are easily limited by fixed structures. Welding of a 300mm product can only target its directly exposed parts. If large-angle welding, such as 360 degrees or 270 degrees, is desired, a second welding operation must be performed at a different workstation. This process is cumbersome, has low welding precision, and, more importantly, is inefficient. It is gradually failing to meet the growing demands for automation and production precision.

[0039] Based on this, this application proposes a welding auxiliary device. The welding auxiliary device achieves a 360-degree rotation of the second port on the mounting protrusion 151 through the cooperation of the first gear 132, the second gear 140 and the mounting protrusion 151. The welding laser focus performs welding operation on the product 300 through the second port and rotates synchronously with the second port, thereby realizing a 360-degree welding operation on the product 300.

[0040] The following reference Figure 1 , Figure 4 and Figure 6 This application describes a welding auxiliary device according to an embodiment.

[0041] It is understood that the welding auxiliary device of this application embodiment includes: a bracket 100, a first mounting plate 120, a first gear 132, a second gear 140, a connector 150, and a first pressing assembly; the bracket 100 is provided with a first driving assembly 110; the first mounting plate 120 is disposed on the bracket 100, and the first mounting plate 120 is provided with a first through-hole and a second driving assembly 130, the first driving assembly 110 being used to drive the first mounting plate 120 to move in the vertical direction; the first gear 132 is connected to the second driving assembly 130; the second gear 140 is provided with a third through-hole, and the second gear 140 is connected to the first gear 132. 2. Engaging connection: The second drive assembly 130 drives the first gear 132 to rotate the second gear 140; the connector 150 is movably connected to the inner wall of the first port, and the inner wall of the connector 150 is provided with a mounting protrusion 151. A second port is provided between the mounting protrusion 151 and the inner wall of the connector 150. The second port is used for the welding laser focus to pass through. The connector 150 is located on the second gear 140, and a third port is located directly above the second port. The second gear 140 is used to drive the mounting protrusion 151 to rotate; the first pressing assembly is connected to the mounting protrusion 151, and the pressing assembly is used to press the product 300.

[0042] The beneficial effects of the welding auxiliary device in this application embodiment are as follows: By providing a first driving component 110, the first mounting plate 120 is driven to move the first pressing component along the vertical direction of the bracket 100, thereby achieving a pressing operation on the product 300. This effectively avoids the adverse effects caused by the product 300 detaching during the welding process. The second opening in the connector 150 allows the welding laser focus to contact the product 300 through the second slot. The second driving component 130 drives the first gear 132 to rotate, thereby driving the second gear 140 and the mounting protrusion 151. The welding auxiliary device of this application operates as follows: the first drive assembly 110 drives the first mounting plate 120 to move vertically along the bracket 100 to press the product 300; the second drive assembly 130 drives the first gear 132 to rotate within a 360-degree range; the first gear 132 drives the second gear 140 meshing with it to rotate; the second gear 140 drives the connector 150 to rotate; the second port on the connector 150 also rotates accordingly; the welding laser focus welds to the product 300 through the second port and rotates synchronously with the second port, thereby achieving 360-degree welding of the product 300.

[0043] For example, in some embodiments, reference is made to Figure 1 , Figure 4 and Figure 6In this embodiment, both the first drive assembly 110 and the second drive assembly 130 are servo electric cylinders. The first drive assembly 110 is located on one side of the bracket 100. A fifth mounting plate 111 is provided above the first drive assembly 110. A floating joint 112 is provided on the side of the fifth mounting plate 111 away from the first drive assembly 110. The first drive assembly 110 and the floating joint 112 are mechanically connected. A first connecting plate 113 is provided on the side of the floating joint 112 away from the first drive assembly 110. The first connecting plate 113 is connected to the first mounting plate 120 through a second connecting plate 114, thereby enabling the first drive assembly 110 to move intermittently. The first mounting plate 120 is driven by a cylinder. When the cylinder extends, the floating joint 112 is lifted, which in turn drives the first mounting plate 120, which is connected to the first connecting plate 113 via the second connecting plate 114, to rise. When the cylinder retracts, the floating joint 112 also retracts, which in turn drives the first mounting plate 120 to fall. This controls the lifting and lowering state of the first mounting plate 120. A third mounting plate 131 is provided on the first mounting plate 120, and a second drive assembly 130 is provided on the third mounting plate 131. The first mounting plate 120 has a groove, and the third mounting plate 131 is located directly above the groove. The second drive assembly 130 is connected to the first gear 132 via a third connecting rod. The first gear 132 is located in a groove, and the second gear 140 meshes with the first gear 132. Thus, the second drive assembly 130 can drive the first gear 132 to rotate the second gear 140 360 degrees. The second gear 140 is mounted on the connector 150, enabling the second gear 140 to rotate the connector 150 360 degrees. The connector 150 is located within the first opening and is movably connected to the inner wall of the first opening. The connector 150 has a ring structure, and its inner wall is provided with a mounting protrusion 151. The mounting protrusion 151 is used to mount the first pressing assembly, so that the first pressing assembly can drive the first mounting plate 120 through the first driving assembly 110 during welding, thereby driving the first pressing assembly to achieve the pressing operation of the product 300. There is also a second opening between the mounting protrusion 151 and the side wall of the connector 150. The second opening is approximately "U" shaped. The third opening is located directly above the second opening, so that the welding laser focus can smoothly pass through the third opening and the second opening to weld the product 300. The welding laser focus rotates synchronously with the connector 150 along the second opening, thereby preventing the mounting protrusion 151 from blocking the welding laser focus.

[0044] It should be noted that the angle at which the second drive assembly 130 drives the first gear 132 to rotate can also be 270 degrees or 300 degrees, etc., and the shape of the second opening can also be a semi-circular arc, mainly to avoid the mounting protrusion 151 blocking the welding laser focus.

[0045] It is understood that the first pressing assembly includes a first pressing block 160, a first connecting rod 161, and a needle roller bearing 162. The mounting protrusion 151 has a slot on the side away from the second gear 140. The needle roller bearing 162 is sleeved on one end of the first connecting rod 161 and engaged in the slot. The other end of the first connecting rod 161 is connected to the first pressing block 160. The needle roller bearing 162 and the first connecting rod 161 are movably connected.

[0046] For example, in some embodiments, referring to the figures, Figure 1 and Figure 5 In this embodiment, the first pressing assembly is also provided with a bearing 163. The bearing 163 and the needle roller bearing 162 are sequentially sleeved on the end of the first connecting rod 161 near the connecting member 150. The end of the connecting member 150 away from the second gear 140 is provided with a groove. The bearing 163 and the needle roller bearing 162 are both engaged in the groove. Thus, when the connecting member 150 rotates, it will also drive the bearing 163 and the needle roller bearing 162 to rotate. The first connecting rod 161 is movably connected to the bearing 163 and the needle roller bearing 162. Therefore, when the bearing 163 and the needle roller bearing 162 rotate, the first connecting rod 161 can also remain stationary. This achieves 360-degree welding of the product 300 while also tightly pressing the product 300, ensuring that the product 300 will not easily shift. The first pressing block 160 is an insulated elastic structure, which can better press the product 300. At the same time, due to its insulation properties, it also plays a certain role in protecting the product 300. The design of the bearing 163 and the needle roller bearing 162 reduces the friction coefficient between the first connecting rod 161 and the groove, making the rotation of the connecting piece 150 smoother.

[0047] It is understood that the welding auxiliary device of this application also includes a second pressing assembly, which is located at the end of the mounting plate away from the bracket 100.

[0048] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the second pressing component is located at one end of the first mounting plate 120 away from the bracket 100, so as to press the other end of the product 300 by the first pressing component, prevent the product 300 from tilting, and further fix the position of the product 300 during welding.

[0049] It is understood that the welding auxiliary device of this application also includes a second mounting plate 170, and the second pressing assembly includes a second connecting rod 180 and a second pressing block 181. One end of the second connecting rod 180 is connected to the first mounting plate 120 through the second mounting plate 170, and the other end is connected to the second pressing block 181. The second pressing assembly and the first pressing assembly are located on the same side of the first mounting plate 120.

[0050] For example, in some embodiments, reference is made to Figure 1 and Figure 5 In this embodiment, the second connecting rod 180 is a linear bearing. One end of the second connecting rod 180 is connected to the end of the second mounting plate 170 away from the bracket 100 via a connecting rod shaft. The second connecting rod 180 and the connecting rod shaft are in a sliding fit to reduce wear between them, thereby extending their service life and reducing costs. The second pressing block 181 is located at the other end of the second connecting rod 180. The second pressing block 181 is used to press the product 300. The second pressing assembly and the first pressing assembly are located on the same side, which facilitates the simultaneous pressing of the product 300.

[0051] It is understandable that the second pressing block 181 and the second connecting rod 180 are connected by a spring.

[0052] For example, in this embodiment, the second pressing block 181 and the second connecting rod 180 are connected by a spring (not shown in the figure), which facilitates the second pressing assembly to better press the product 300. At the same time, since the spring is an elastic structure, it also avoids the situation where the product 300 is damaged due to excessive pressing.

[0053] It is understood that the welding auxiliary device of this application also includes a guide rail assembly 115, which is disposed on the side of the bracket 100 near the first mounting plate 120. The first mounting plate 120 is disposed on the guide rail assembly 115, and the guide rail assembly 115 is used to drive the first mounting plate 120 to move along the vertical direction of the bracket 100.

[0054] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the first mounting plate 120 is fixedly connected to the guide rail assembly 115, thereby the guide rail assembly 115 provides a certain support for the first mounting plate 120. At the same time, the guide rail assembly 115 moves along the vertical direction of the bracket 100, thereby driving the first mounting plate 120 to move. This reduces the friction when the first drive assembly 110 drives the first mounting plate 120 to lift and lower, and also makes the lifting and lowering operation of the first mounting plate 120 faster and smoother, making the operation more efficient.

[0055] It is understood that the welding auxiliary device of this application also includes an adjustable base, which includes a first base plate 200, a second base plate 210, a first adjusting plate 201, a second adjusting plate 211, a first adjusting screw, and a second adjusting screw. The bracket 100 is disposed on the first base plate 200. The first adjusting plate 201 is disposed on the side wall of the first base plate 200 through the first adjusting screw. The first base plate 200 can move along the length direction of the first adjusting screw. The second base plate 210 is disposed on the side of the first base plate 200 away from the bracket 100. The second adjusting plate 211 is disposed on the side wall of the second base plate 210 through the second adjusting screw. The second base plate 210 can move along the length direction of the second adjusting screw. The direction in which the first base plate 200 can move is perpendicular to the direction in which the second base plate 210 can move.

[0056] For example, in some embodiments, reference is made to Figure 2 and Figure 3 In this embodiment, the bracket 100 is mounted on the first base plate 200 via the fourth mounting plate 190. The first adjusting plate 201 is mounted on the side wall of the first base plate 200 and is movably connected to the first base plate 200 via the first adjusting screw. The first base plate 200 can move along the length direction of the first adjusting screw. The second base plate 210 is located on the side of the first base plate 200 away from the fourth mounting bracket. The second adjusting plate 211 is mounted on the side wall of the second base plate 210 and is movably connected to the second base plate 210 via the second adjusting screw. The second base plate 210 can move along the length direction of the second adjusting screw. The length direction of the first adjusting screw is perpendicular to the length direction of the second adjusting screw, thereby adjusting the position of the bracket 100 and consequently adjusting the position of the connector 150. This avoids the initial position of the mounting protrusion 151 from blocking the welding laser focus. Multiple first base plates 200 can be mounted on the second base plate 210 simultaneously to facilitate the coordinated operation of multiple welding auxiliary devices.

[0057] It is understood that the welding auxiliary device of this application also includes a gasket 133. The first drive assembly 110 is connected to the first gear 132 through a third connecting rod. The third connecting rod passes through the first gear 132 and the gasket 133 in sequence and is fixedly connected to the gasket 133. The gasket 133 abuts against the first gear 132.

[0058] For example, in some embodiments, reference is made to Figure 5 In this embodiment, one end of the third connecting rod is fixedly connected to the second driving assembly 130, and the other end is inserted through the first gear 132 and the first washer 133. The first washer 133 is fixed to the other end of the third connecting rod and is connected to the side of the first gear 132 away from the first driving assembly 110, thereby realizing the supporting effect of the washer 133 on the first gear 132, which can effectively prevent the first gear 132 from disengaging from the third connecting rod when rotating.

[0059] It is understood that the welding auxiliary device of this application also includes a connecting ring 152, which is sleeved on the side wall of the connector 150, and the connector 150 is movably connected to the first port through the connecting ring 152.

[0060] For example, in some embodiments, reference is made to Figure 6 In this embodiment, the connecting ring 152 is a ring bearing. The connecting ring 152 is sleeved on the side wall of the connector 150, and the inner side wall of the connecting ring 152 is engaged with the side wall of the connector 150. The outer side wall of the connecting ring 152 is movably connected to the side wall of the first port. When the connector 150 rotates, the connecting ring 152 will also be driven to rotate. The connecting ring 152 is provided to reduce the wear of the connector 150, extend the service life of the connector 150, and reduce costs.

[0061] The welding apparatus according to the second aspect of the application includes the welding auxiliary apparatus of the first aspect of the application described above.

[0062] According to the welding apparatus of this application embodiment, a first driving component 110 is provided, which drives the first mounting plate 120 to move the first pressing component along the vertical direction of the bracket 100, thereby achieving a pressing operation on the product 300. This effectively avoids the adverse effects caused by the product 300 detaching during the welding process. By providing a second opening in the connector 150, the welding laser focus can contact the product 300 through the second slot. By providing a second driving component 130, the first gear 132 is driven to rotate, thereby driving the second gear 140 and the mounting protrusion 151 to rotate. The welding auxiliary device of this application operates as follows: The first drive assembly 110 drives the first mounting plate 120 to move vertically along the bracket 100 to press the product 300. The second drive assembly 130 drives the first gear 132 to rotate within a 360-degree range. The first gear 132 drives the second gear 140, which meshes with it, to rotate. The second gear 140 drives the connector 150 to rotate, and the second port on the connector 150 also rotates accordingly. The welding laser focus welds to the product 300 through the second port and rotates synchronously with the second port, thereby achieving 360-degree welding of the product 300. By using the welding auxiliary device of this application, the welding efficiency of the welding equipment is improved.

[0063] Since the welding equipment includes the welding auxiliary device of the first aspect embodiment, the corresponding contents of the welding auxiliary device in the first aspect embodiment can be applied to the welding equipment of the second aspect, and have the same implementation principle and technical effect. To avoid redundancy, it will not be described in detail here.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
