[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Reference Figures 1 to 4 and Figure 8 , which is the first embodiment of the present invention, and provides a roller welding device, comprising a support unit 1, including a base 11, a support frame 12 arranged above the base 11, a telescopic assembly 13 arranged between the support frame 12 and the base 11, a driving assembly 14 arranged at the top of the support frame 12, and a welding robot 15 arranged at the top of the support frame 12;

[0038] It should be noted that the support frame 12 is located above the base 11, and a telescopic assembly 13 is arranged between the two. When the roller is not placed on the driving assembly 14, the telescopic assembly 13 lifts the support frame 12 upward. When the roller is placed on the driving assembly 14, the telescopic assembly 13 will shrink, driving the support frame 12 to move downward. Multiple sets of driving assemblies 14 are fixedly connected to the support frame 12. In addition to supporting the placement of the roller, the multiple sets of driving assemblies 14 can also drive the roller to rotate. On both sides of the support frame 12, welding robots 15 are arranged, and the welding robots 15 are fixedly installed on the base 11.

[0039] The pushing unit 2 includes a fixing plate 21 disposed on both sides of the support frame 12, a fixing assembly 22 disposed on both sides of the fixing plate 21, a linear moving assembly 23 disposed at the bottom of the fixing plate 21, and a pushing assembly 24 disposed on one side of the fixing plate 21;

[0040] The fixing plate 21 is at the same height as the roller body 41 in the welding state;

[0041] It should be noted that the fixed plate 21 is located on both sides of the supporting frame 12, and a linear moving component 23 is fixedly connected to the lower surface of the fixed plate 21, and the linear moving component 23 is fixedly installed on the base 11. When the roller is not placed on the driving component 14, the horizontal height of the fixed plate 21 is lower than the driving component 14. When the roller is placed on the driving component 14, the fixed plate 21 is at the same horizontal height as the roller body 41. In the pre-welding state and the welding state, the roller is located on the driving component 14. Fixed components 22 are fixedly connected to the outer walls on both sides of the fixed plate 21. The fixed components 22 are opened and locked by the movement of the moving end of the linear moving component 23. A pushing component 24 is fixedly connected to the end of the fixed plate 21 away from the supporting frame 12. The pushing component 24 is moved close to and away from the supporting frame 12 by the movement of the moving end of the linear moving component 23.

[0043] The moving end of the fixed component 22 and the moving end of the pushing component 24 are both connected to the moving end of the linear moving component 23, the first rotating plate 33 is rotatably connected to the outer wall of the supporting frame 12, and one end of the second rotating plate 34 is connected to the moving end of the linear moving component 23;

[0044] It should be noted that the conduit 31 is fixedly embedded in the inner walls on both sides of the base 11, and a connecting rod 32 is slidably connected to the inner wall of the conduit 31, and the two ends of the connecting rod 32 are rotatably connected to the first rotating plate 33 and the second rotating plate 34 respectively, the top of the first rotating plate 33 is rotatably connected to the outer wall of the supporting frame 12, and one end of the second rotating plate 34 is rotatably connected to the moving end of the linear moving component 23.

[0045] The roller unit 4 includes a roller body 41 placed on the driving assembly 14 and shaft heads 42 arranged at both ends of the roller body 41 .

[0046] When in use, the shaft head 42 is placed in the fixing assembly 22 on the fixing plate 21, and the fixing assembly 22 fixes the shaft head 42;

[0047] The roller body 41 is placed on the driving assembly 14, and the telescopic assembly 13 is contracted to drive the support frame 12 to move downward. During the downward movement of the support frame 12, the connecting rod 32 is pushed outward through the first rotating plate 33. When the connecting rod 32 slides outward, it pulls the moving end of the linear moving assembly 23 to move downward.

[0048] When the linear moving component 23 moves downward, the fixed space is opened, and at the same time, the pushing component 24 is inserted into the tail end of the shaft head 42 and pushes the shaft head 42 to insert into both ends of the roller body 41, and then the driving component 14 is started to drive the roller body 41 to rotate;

[0049] Finally, the welding robot 15 is started to weld the contact portion between the roller body 41 and the shaft head 42 .

[0050] In summary, by placing the roller body 41 on the supporting frame 12, the telescopic component 13 contracts to drive the supporting frame 12 to move downward, and the downward movement of the supporting frame 12 drives the fixing component 22 to open, and at the same time, the shaft head 42 is inserted into the roller body 41 through the pushing component 24, and then the roller body 41 is driven to rotate and welding is performed, thereby realizing automated welding and solving the problems of complex welding process and too many manual operation steps in the existing roller welding process.

[0059] During use, when the roller body 41 is placed on multiple sets of driving wheels 142, the cylinder 133 contracts to drive the supporting frame 12 to move downward. After the shaft head 42 is inserted, the multiple sets of motors 141 are started, and the motors 141 drive the driving wheels 142 to rotate, thereby driving the roller body 42 to rotate.

Grooves are provided at the near ends of the two fixed arms 222. The two grooves constitute a fixed space, and a third rotating plate 223 is arranged between the fixed arm 222 and the connecting column 235.

[0066] During use, when the connecting column 235 pulls the third rotating plate 223 downward, the third rotating plate 223 will drive the fixed arm 222 to rotate on the fixed seat 221, and the fixed arm 222 rotates to open the fixed space to achieve the opening effect. When the roller is removed, the connecting column 235 moves upward, driving the third rotating plate 223 to push the fixed arm 222 upward, and the fixed arm 222 rotates.
