Description

Technical Field

[0001] The utility model relates to a metal welding machine, in particular to a copper busbar soft connection welding machine. Background Art

[0002] In the power and electronics industries, soft connection welding of copper bars is an important process to ensure stable current transmission and reliable operation of equipment. The traditional welding method requires that several layers of copper bars be precisely stacked and then heated at high temperature by a welding machine to cause molecular diffusion between the copper bars to achieve soft connection. However, this method has some problems in actual operation.

[0003] First, the copper busbars need to be precisely stacked before welding, but during the welding process, they often shift due to thermal expansion or equipment vibration. This shift may cause the copper busbars to be arranged unevenly after welding, affecting the stability and aesthetics of the connection. In addition, position shift may also lead to uneven welding, thus affecting the transmission efficiency and safety of the current.

[0004] In order to solve the above problems, the present application proposes an improved copper busbar soft connection welding machine design. The new welding machine introduces a positioning fixture to ensure the stability of the copper busbar during the welding process. The positioning fixture can fix the position of the copper busbar before welding to prevent it from shifting during heating. Utility Model Content

[0005] The utility model aims to provide a copper bar soft connection welding machine, which can automatically adjust the positions of the stacked copper bars, thereby ensuring that the copper bars are neatly arranged during welding.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0040] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like 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 a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0041] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0042] like Figure 1 As shown, a copper busbar flexible connection welding machine includes a frame 1. A welding plate 2 is arranged on one side of the frame 1. A driving cylinder 3 is connected to the welding plate 2 to drive the welding plate 2 to move up and down. Among them, a heating device (not shown in the figure) is connected to one side of the welding plate 2 through the copper busbar. The heating device is used to heat the welding plate 2 at a high temperature. A workbench 4 is arranged below the welding plate 2. The contact surface between the workbench 4 and the welding plate 2 is a plane.

[0043] The core technical solution of this application is as follows:

[0044] like Figure 1-Figure 3 As shown, a positioning bracket 5 is provided on one side of the workbench 4 and is arranged flush with the workbench 4. A storage space 6 for placing multiple layers of copper bars is provided on the positioning bracket 5. The area of ​​the storage space 6 is adapted to the size of the copper bar, and can also be larger than the copper bar.

[0045] When the staff needs to perform molecular diffusion welding on the multi-layer copper busbars, they place the copper busbars in the storage space 6 and stack them one by one, and the storage space 6 wrapped by the positioning bracket 5 is precisely arranged and stacked, thereby ensuring that the stacked copper busbars are stably placed. Compared with the existing method of manually holding the copper busbars and placing them on the workbench 4, the copper busbars can be arranged neatly to a greater extent.

[0046] In order to solve the problem that after the diffusion welding of the copper bar is completed, the surface temperature of the copper bar is high, it is difficult to output and may cause potential safety hazards. The present application is slidably connected with a slide plate 7 in the placement space. The height of the slide plate 7 can be higher than the height of the stacked copper bars. The slide plate 7 can be used to limit the arrangement of the copper bars. Correspondingly, a connecting plate 8 is connected to one side of the slide plate 7. The connecting plate 8 is in the shape of a "door". One end of the connecting plate 8 is connected to a square frame 9. The frame 9 is slidably arranged with the positioning bracket 5, and the setting method is a T-block connection.

[0047] The middle of the frame 9 is hollow, and a cam 10 is arranged in the middle of the frame 9. The cam 10 is connected to a driving shaft 11. The driving shaft 11 is connected to a driving motor 12.

[0048] Optimally, a recovery box 13 is provided on one side of the positioning bracket 5. Cooling water is provided in the recovery box 13 to facilitate the subsequent high-temperature cooling of the copper busbar.

[0049] The overall process is as follows:

[0050] 1. Place multiple copper bars in the placement space, with one end of each copper bar abutting against the slide plate 7 for alignment, to ensure that multiple layers of copper bars are accurately stacked;

[0051] 2. Under the action of the driving cylinder 3, the welding plate 2 moves down to abut against the copper busbar of the first layer, that is, Figure 4 As shown, a welding position 14 is provided on the copper bar, and the molecules between the copper bars are diffused by high temperature heating, so that the copper bars of each layer are welded and bonded (such as Figure 4 shown);

[0052] 3. After welding is completed, the driving cylinder 3 drives the welding plate 2 to reset. The driving motor 12 works in steps, and the stepping amplitude is 180°. The driving motor 12 drives the cam 10 to rotate. The far end of the cam 10 contacts the left and right sides of the frame 9 in turn (such as Figure 1 The frame 9 first moves to the left, causing the slide plate 7 connected to the connecting plate 8 to move to the left. The slide plate 7 moves to the left, pushing the copper bar to the left, and finally the copper bar is pushed out of the positioning bracket 5 and falls into the recovery box 13 under the action of gravity for cooling.

[0053] 4. The frame 9 moves to the right and resets under the action of the drive motor 12;

[0054] 5. Repeat the above steps to achieve the purpose of accurately stacking and automatically recycling several layers of copper busbars.

[0055] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
