[0043] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0044] like Figure 1-6 As shown, the following embodiment discloses a welding device for a round tube external component.

[0045] A round tube external fitting welding device, comprising:

[0046] The rotary mechanism 200 is used to install the round tube 2 and can drive the round tube 2 to rotate around the central axis;

[0047] The visual recognition mechanism 100 is used to identify and determine the installation position on the round tube 2;

[0048] A loading mechanism 300 is used to take the external component 1 and position it on the round tube 2;

[0049] The welding mechanism 400 is located at the side of the feeding mechanism 300, and when the feeding mechanism 300 places the external component 1 on the round tube 2, the external component 1 and the round tube 2 are welded;

[0050] The conveying mechanism 500 is used to convey the feeding mechanism 300 and the welding mechanism 400;

[0051] The above is the basic solution of this embodiment.

[0052] For details, refer to 1 and Figure 2 As shown, the feeding mechanism 300 and the welding mechanism 400 are arranged on the side of the rotating mechanism. When the round tube 2 is installed on the rotating mechanism and rotates under the action of the rotating mechanism, the feeding mechanism 300 feeds the external hanger 1 and positions the external hanger 1 on the round tube 2, and the welding mechanism 400 welds the external hanger 1 and the outer surface of the round tube 2 to fix the external hanger 1.

[0053] In order to locate the welding position of the external hanger 1, a visual recognition mechanism 100 is provided in this embodiment to recognize the position state of the round tube 2;

[0054] Reference Figure 2 As shown, in this embodiment, the visual recognition mechanism 100 is preferably arranged at one end of the circular tube 2 and located in the middle of the end. When the circular tube 2 rotates, the position of the circular tube 2 after rotation can be determined;

[0055] The round tube 2 rotates, and the visual recognition mechanism 100 performs position recognition, checks the starting point, and positions the round tube 2 to a specified angle. The feeding mechanism 300 takes the external component 1 and places it at a specified position, and the welding assembly welds the external component 1 at the same time. After welding is completed, the conveying mechanism 500 simultaneously conveys the feeding mechanism 300 and the welding mechanism 400, and conveys the set distance. The feeding mechanism 300 and the welding mechanism 400 perform the picking, feeding, and welding operations of the external component 1 again.

[0056] One loading process is the welding of a row of external parts 1 along the axis of the circular tube 2. After completion, the conveying mechanism 500 conveys the loading mechanism 300 and the welding mechanism 400 back to the starting point, and the rotating mechanism drives the circular tube 2 to rotate a set angle, and the second loading is performed again.

[0057] In order to enable the visual recognition mechanism 100 to perform position recognition on the round tubes 2 of different diameters, in this embodiment, the visual recognition mechanism 100 includes a lifting base 120 , and the detection camera 110 is disposed on the lifting base 120 .

[0058] When the diameter of the circular tube 2 is large, its upper end is at a higher position. At this time, the lifting base 120 moves the detection camera 110 upward so that the capturing range of the detection camera 110 can cover the entire end of the circular tube 2 .

[0059] The circular tube 2 is a long tube with a hollow interior, and therefore, a rotating structure is required to fix the circular tube 2 and then drive it to rotate. The specific implementation method for solving this problem in this embodiment is as follows: the rotating mechanism includes a rotating top block 230 for positioning and installing the two ends of the circular tube 2, and at least one side is provided with a rotating drive seat for driving the rotating top block 230 to rotate.

[0060] In this embodiment, the rotating mechanism includes a front seat 210 and a rear seat 220. The front seat 210 is a rotating driving seat. Two rotating top blocks 230 are respectively arranged on two opposite surfaces of the front seat 210 and the rear seat 220. The front seat 210 drives the rotating top block 230 to rotate, thereby driving the circular tube 2 to rotate.

[0061] In this embodiment, the rotating top block 230 is configured as a laterally placed cone or frustum, and the end with a small inner diameter extends into the circular tube 2.

[0062] Reference Figure 3As shown, the rotating top block 230 is set as a small head end facing the circular tube 2, and a support is formed between the outer circumferential surface of the rotating top block 230 and the end of the circular tube 2. After the two rotating top blocks 230 clamp the circular tube 2, there is a great static friction between the circular tube 2 and the rotating top block 230, so that the rotating top block 230 on the front seat 210 can drive the circular tube 2 to rotate, and the rotating top block 230 on the rear seat 220 rotates with the circular tube 2.

[0063] Since the circular tube 2 is relatively long, the rotating top block 230 only supports the two ends of the circular tube 2. Therefore, during the rotation process, the middle part of the circular tube 2 will produce a certain amount of shaking or vibration due to unstable installation. In this embodiment, the rotating mechanism also includes a rolling support frame 240. The rolling support frame 240 is provided with a supporting part, and the supporting part is tangent to the outer surface of the circular tube 2 to support the circular tube 2.

[0064] Reference Figure 3 As shown, the rolling support frame 240 is arranged in the middle of the circular tube 2, and a plurality of rolling support frames 240 can be arranged according to the length of the circular tube 2.

[0065] The supporting part supports the outer circumference of the circular tube 2 . When the circular tube 2 rotates, a relative movement occurs between the supporting part and the circular tube 2 , but the supporting height remains unchanged, thereby ensuring the stability of the circular tube 2 .

[0066] In this embodiment, the specific implementation of the rolling support frame 240 is as follows: at least two symmetrical rollers 250 are arranged on the rolling support frame 240 , and the axes of the rollers 250 are parallel to the axis of the circular tube 2 ; and the supporting part is located between the two rollers 250 .

[0067] Specific reference Figure 4 As shown, two rollers 250 are installed on the rolling support frame 240, and the supporting part thereof is the contact part between the rollers 250 and the round tube 2, and the supporting part has different positions according to the different diameters of the round tube 2.

[0068] During the supporting process, a V-shape is formed between the supporting part and the center of the rolling support frame 240, that is, the rolling support frame 240 and the roller 250 provide V-shaped support for the circular tube 2, ensuring that the same set of support frames and rollers can be used for support at different heights or for circular tubes 2 of different diameters.

[0069] In order to reduce the friction between the roller 250 and the round tube 2 , in this embodiment, the roller 250 is rotatably connected to the rolling support frame 240 .

[0070] Reference Figure 4 As shown, a roller 250 mounting seat is provided on the rolling support frame 240, and the roller 250 mounting seat is rotatably mounted on the roller 250 mounting seat;

[0071] When the round tube 2 rotates, the roller 250 is driven to rotate together, thereby achieving a rolling connection with the roller 250 and reducing friction.

[0072] In this embodiment, in order to facilitate the operator to adjust the supporting part of the round tube 2, a supporting slide 270 is also included, and the rolling support frame 240 is slidably installed on the supporting slide 270.

[0073] In this embodiment, the support slide 270 is configured as a conventional slide rail, and the rolling support frame 240 is slidably installed through the slide rail. The operator can adjust the position of the rolling support frame 240 to evenly support the round tube 2.

[0074] In this embodiment, the feeding mechanism 300 includes a feeding robot 310 , on which a material picking assembly is disposed, and the conveying mechanism 500 is provided with a feeding plate 320 .

[0075] The loading robot 310 is a conventional robot, and a material taking component is arranged at the end thereof. The material taking component takes materials from the loading plate 320 and then places the external component 1 to the designated position of the round tube 2.

[0076] Specifically, in this embodiment, the material picking assembly includes a material picking plate 360 ​​, and the material picking plate 360 ​​is adjustably disposed on the loading robot 310 .

[0077] Specific reference Figure 6 As shown, a fixing plate 330 is provided on the feeding manipulator 310, and the back of the picking plate 360 ​​is connected to the manipulator via a spring 350, so that the picking plate 360 ​​can be offset relative to the feeding manipulator 310 or relative to the fixing plate 330. In order to ensure that its convenient position is a straight line, in this embodiment, a guide column 340 is provided between the fixing plate 330 and the picking plate 360, and an avoidance hole that enables the guide column 340 to slide is provided on the fixing plate 330; one end of the guide column 340 is fixed to the back of the picking plate 360; at the same time, the spring 350 is sleeved on the guide column 340;

[0078] During the material picking process, the picking plate 360 ​​moves to the top of the loading plate 320 under the action of the loading robot 310, and descends to a position where it can contact the external plug-in 1 on the loading plate 320, sucks the external plug-in 1, and then takes the external plug-in 1 away through the loading robot 310.

[0079] In this embodiment, the picking plate 360 ​​is set as a magnet that can adsorb the external component 1. The purpose of setting the spring 350 is to ensure that the picking plate 360 ​​can contact the external component 1. When the picking plate 360 ​​contacts the external component 1, the head position of the loading robot 310 is as low as possible to squeeze the spring 350, thereby ensuring that the picking plate 360 ​​and the external component 1 are in contact.

[0080] In other embodiments, other material-retrieving components with adsorption function may also be provided; compared with the material-retrieving method of clamping, in this embodiment, the external component 1 is adsorbed and placed on the round tube 2, which does not affect the welding of the external component 1 by the welding mechanism 400.

[0081] In this embodiment, the welding mechanism 400 includes a welding manipulator 410 , and the head of the welding manipulator 410 is configured as a welding head 420 ;

[0082] A welding wire barrel (not shown) is disposed on the side of the welding robot 410 .

[0083] In this embodiment, after the feeding mechanism 300 takes the material, it places the external component 1 at the specified position of the round tube 2, and the welding robot 410 welds it after soaking the welding wire from the welding wire barrel. Therefore, the feeding mechanism 300 and the welding mechanism 400 work almost simultaneously; therefore, when the feeding robot 310 is moved, the welding mechanism 400 needs to be moved at the same time to ensure that the welding mechanism 400 and the feeding mechanism 300 can cooperate with each other.

[0084] In this embodiment, a moving plate is provided on the conveying mechanism 500 , and the feeding mechanism 300 and the welding mechanism 400 are both provided on the moving plate and move on the conveying mechanism 500 along with the moving plate.

[0085] In this embodiment, the conveying mechanism 500 is a conventional conveyor belt or a conveyor slide rail.

[0086] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
