[0042] Electron gun welding is a type of welding technology. Depending on different welding requirements, the electron gun can perform welding processing in a vacuum environment or a low vacuum environment.

[0043] The existing electron gun welding equipment has the problems of poor operation stability and low transmission accuracy when the electron gun has a large movement stroke during the welding process.

[0044] The utility model provides a welding device, which is applied to a welding chamber (not shown), wherein the welding chamber can be a vacuum welding chamber or a low vacuum welding chamber.

[0045] See also Figures 1 to 4 In one embodiment of the present invention, the welding device comprises:

[0046] The frame 100 is fixed to the welding chamber. Specifically, the frame 100 can be fixed to the box (not shown) of the welding chamber by bolts.

[0047] The first multi-axis driving member 200 and the electron gun 300 are installed on the frame 100; the electron gun 300 is connected to the first multi-axis driving member 200, and the first multi-axis driving member 200 drives the electron gun 300 to move. In this embodiment, by installing the first multi-axis driving member 200 on the frame 100 and driving the electron gun 300 to move, the first multi-axis driving member 200 can be made more stable when in use. Specifically, the frame 100 structure has good stability, which can make the first multi-axis driving member 200 drive the electron gun 300 more stable during the movement, thereby making the movement accuracy of the electron gun 300 higher, thereby solving the technical problems existing in the prior art. At the same time, when the welding equipment of the present application is used in a vacuum or low vacuum welding chamber, under the action of the frame 100 structure, when the vacuum chamber is evacuated, the frame 100 structure has good rigidity, which can reduce the impact of the vacuum chamber deformation on the electron gun 300. In addition, the frame 100 of the present application serves as a carrier of the electron gun 300, and the interactive range of the electron gun 300 can be designed according to the structure of the frame 100. That is to say, as the structure of the frame 100 increases, the active range of the electron gun 300 can be effectively increased, thereby increasing the effective welding stroke of the electron gun 300.

[0048] In one embodiment, reference Figure 1 、 Figure 3The first multi-axis driving member 200 includes a first driving mechanism 210, a second driving mechanism 220, and a third driving mechanism 230. The first driving mechanism 210 is installed on the frame 100. The first driving mechanism 210 is driven and connected with the second driving mechanism 220 so that the second driving mechanism 220 moves along a first direction. The second driving mechanism 220 is driven and connected with the third driving mechanism 230 so that the third driving mechanism 230 moves along a second direction, wherein the second direction is the height direction of the frame 100. The third driving mechanism 230 is driven and connected with the The electron gun 300 is driven and connected to move along a third direction. The first direction, the second direction, and the third direction are arranged at a predetermined angle relative to each other. Furthermore, the first multi-axis drive member 200 utilizes the aforementioned modular design, enabling the first drive mechanism 210, the second drive mechanism 220, and the third drive mechanism 230 to operate independently. In other words, the first drive mechanism 210, the second drive mechanism 220, and the third drive mechanism 230 can operate synchronously, moving the electron gun 300 to a predetermined position at the fastest rate, thereby improving production efficiency. In this embodiment, the first direction, the second direction, and the third direction are arranged at a 90-degree angle relative to each other. In other embodiments, the first direction and the second direction may be arranged at a 60-degree angle, the second direction and the third direction may be arranged at a 120-degree angle, and so on.

[0049] Furthermore, in this embodiment, when the first driving mechanism 210, the second driving mechanism 220 and the third driving mechanism 230 operate simultaneously, the electron gun 300 can simultaneously operate in the first direction, the second direction and the third direction, so that the electron gun 300 reaches the preset position at the fastest speed.

[0050] In one embodiment, referring to the figure, the first driving mechanism 210 includes a first guide rail 211 and a first driving component 212 installed on the frame 100, the second driving mechanism 220 is installed on the first guide rail 211, and the first driving component 212 is driven and connected to the second driving mechanism 220. Specifically, the first guide rail 211 is fixed to the frame 100, and the second driving mechanism 220 is installed on the first guide rail 211. At this time, the first driving component 212 can drive the second driving mechanism 220 to move along the first guide rail 211.

[0051] In one embodiment, reference Figure 1 、 Figure 5, the first guide rail 211 is configured as two groups, and the two groups of the first guide rails 211 are respectively arranged on the opposite sides of the frame 100; the second driving mechanism 220 includes two second driving components 221, and the two second driving components 221 are respectively installed on the two first guide rails 211. Since the first guide rails 211 are arranged on the opposite sides of the frame 100, the two second driving components 221 are also arranged on the opposite sides of the frame 100; the two second driving components 221 are both driven and connected to the third driving mechanism 230. Specifically, the third driving mechanism 230 is connected to the opposite sides of the frame 100. Since the two second driving components 221 are both driven and connected to the third driving mechanism 230, at this time, the third driving mechanism 2 30 is subjected to driving forces at two locations, and the driving forces at the two locations are respectively located on two opposite sides of the frame 100. In this way, when the second driving mechanism 220 drives the third driving mechanism 230 to move in the second direction, the two second driving components 221 can be driven synchronously, so that the positions of the third driving mechanism 230 near the two opposite sides of the frame 100 can all be subjected to driving forces, thereby making the third driving mechanism 230 more stable when moving in the second direction; in this embodiment, the two second driving components 221 are drivingly connected to the third driving mechanism 230. At this time, when the first driving component 212 drives the second driving component 221 to move along the first guide rail 211, the third driving mechanism 230 can also move along the first guide rail 211. At the same time, in this embodiment, the first driving component 212 can be provided in two groups, and the two groups of first driving components 212 are respectively provided corresponding to the two groups of first guide rails 211. In other words, the two groups of first driving components 212 are provided in a one-to-one correspondence with the two groups of second driving mechanisms 220 and are drivingly connected thereto.

[0052] In one embodiment, reference Figure 3 The first drive component 212 is driven and connected to the second drive component 221. At this time, when the first drive component 212 drives a second drive component 221 to move along the first guide rail 211, the force can be transmitted to another second drive component 221 through the third drive mechanism 230, so that the other second drive component 221 moves along the first guide rail 211. This can reduce the number of first drive components 212 and reduce the cost of welding equipment.

[0053] In one embodiment, reference Figure 3The first drive component 212 includes a first drive motor 2121, two second guide rails 2122 and two transmission parts.

Specifically, the first drive component 212 can drive the relative ends of the second drive component 221 to move synchronously, so that the second drive component 221 can move more smoothly along the first guide rail 211, and the swing of the second drive component 221 is smaller.

[0054] In one embodiment, reference Figure 1 、 Figure 2 The third driving mechanism 230 includes a third guide rail 231, a third driving component 232 fixed to the third guide rail 231, and two second driving components 221 are respectively connected to the opposite ends of the third guide rail 231 to synchronously drive the opposite ends of the third guide rail 231 to move along the second direction. The electron gun 300 is slidably mounted on the third guide rail 231, and the third driving component 232 is connected to the electron gun 300. Furthermore, the two second driving components 221 are respectively connected to the opposite ends of the third guide rail 231. At this time, the first driving component 212 drives one of the second driving components 221 to move along the first When the electron gun 300 moves in the first direction, the other second driving assembly 221 can be moved in the first direction through the third guide rail 231. At the same time, in this embodiment, the electron gun 300 is slidably mounted on the third guide rail 231. When the third guide rail 231 follows the two second driving assemblies 221 to move in the first direction, the electron gun 300 can also follow it to move in the first direction. At the same time, the two second driving assemblies 221 can drive the third guide rail 231 to move in the second direction. At this time, the electron gun 300 can also move in the second direction. Since the third driving assembly 232 is fixed to the third guide rail 231, the third driving assembly 232 can drive the electron gun 300 to move in the third direction.

[0055] In one embodiment, the first drive assembly 212, the second drive assembly 221, and the third drive assembly 232 are configured as closed linear motion modules. Further, the use of closed linear motion modules can significantly reduce the pollution of transmission components by dust and splashes during welding, reducing maintenance costs. At the same time, in this embodiment, the closed linear motion module can adopt a closed belt transmission linear drive assembly, a closed gear transmission linear drive assembly, etc. Further, when the second drive assembly 221 adopts a closed linear motion module, a set of guide rails in the second drive assembly 221 is configured as two and driven by a drive member (see Figure 2 、 Figure 3 ).

At the same time, the electron gun 300 can rotate in the fifth direction within a range of 0 to 180 degrees, i.e., the electron gun 300 can rotate in the first direction. However, the present design is not limited thereto.
