DETAILED DESCRIPTION

[0037] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0039] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0040] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] First, the X direction, Y direction and Z direction mentioned in the embodiment of the present application can be referred to in the attached drawings. Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The marked directions. Among them, the X direction, Y direction and Z direction intersect each other.

[0043] like Figure 1-Figure 5As shown, according to the first aspect of an embodiment of the present application, a heating system is provided, comprising a heating mechanism 1 and a preheating mechanism 2; the heating mechanism 1 comprises a heating component 11, the heating component having a heating portion 111, the heating portion 111 being a planar structure, and the heating portion 111 being made of graphene; the preheating mechanism 2 is located below the heating mechanism 1 in the Z direction, the preheating mechanism 1 comprises a heat-saturating component 22, the temperature of the heat-saturating component 22 can be maintained at a preset value to preheat the workpiece to be welded; when the heating system is in use, the heating mechanism 1 and the preheating mechanism 2, the heating mechanism 1 or the preheating mechanism 2 can be used.

[0044] like Figure 1 As shown, the heating system includes a heating mechanism 1 and a preheating mechanism 2. The preheating mechanism 2 is used to place the workpiece to be welded and preheat the workpiece to be welded on the preheating mechanism 2. The preheating mechanism 2 is located below the heating mechanism 1 in the Z direction. The heating mechanism 1 is used to weld the workpiece to be welded on the preheating mechanism 2 at high temperature.

[0045] Further explanation, such as Figure 1 and Figure 2 As shown, the heating mechanism 1 includes a heating component 11, and the heating component 11 has a heating portion 111. The heating portion 111 is a planar structure and is made of graphene. Graphene has a high electrothermal conversion efficiency and can quickly convert electrical energy into thermal energy. Its heating speed is fast, thereby improving welding efficiency. As the temperature of graphene continues to rise, graphene will gradually become a poor conductor of heat, and can confine the temperature to a very small area. Therefore, graphene has good heat-dissipating performance, which can make the parts to be welded more evenly heated, thereby avoiding the occurrence of broken grids, spot defects or cold welds during welding. Graphene can also maintain structural stability even at high temperatures, and has good thermal stability and deformation stability, thereby improving the service life of the heating component 11.

[0046] Further explanation: the preheating mechanism 2 includes a heat-saturating component 22, the temperature of which can be maintained at a preset value, thereby preheating the workpiece to be welded, thereby reducing the temperature difference between the upper and lower surfaces of the workpiece to be welded, thereby improving the welding quality.

[0047] To further illustrate, when the heating system is in use, only the heating mechanism 1, only the preheating mechanism 2, or both the heating mechanism 1 and the preheating mechanism 2 may be used as needed.

[0048] Therefore, in the embodiment of the present application, the preheating mechanism 2 can preheat the workpiece to be welded, and can reduce the temperature difference between the upper and lower surfaces of the workpiece to be welded when the heating mechanism 1 welds the workpiece to be welded. Therefore, during welding, it can avoid uneven heating of the workpiece to be welded and the occurrence of broken grids, spot defects or cold welds. Therefore, the heating system provided in the present application can improve welding quality and welding efficiency.

[0049] In an optional embodiment, the heating portion 11 includes several areas, and the temperature of each area is the same or different to adapt to different parts to be welded.

[0050] To further illustrate, since the heating portion 11 is a planar structure, the plane can be divided into several areas, and the temperature in each area can be the same or different, so that the temperature can be adjusted according to the battery process and different parts to be welded.

[0051] In an optional embodiment, the heating system further includes a controller;

The first temperature sensor is connected to the controller for communication, and the heating component 11 is connected to the controller for communication; when the controller receives a signal from the first temperature sensor that the temperature of the heating part 111 is lower than or exceeds a preset value, the controller sends an instruction to the heating component 11 to control the heating component 11 to adjust so that the temperature of the heating part 111 is controlled to the preset value. The second temperature sensor is arranged on the heat-scaling component 22, and the second temperature sensor is used to detect the temperature of the heat-scaling component 22. The second temperature sensor is connected to the controller for communication, and the heat-scaling component 22 is connected to the controller for communication; when the controller receives a signal from the second temperature sensor that the temperature of the heat-scaling component 22 is lower than or exceeds a preset value, the controller sends an instruction to the heat-scaling component 22 to control the heat-scaling component 22 to adjust so that the temperature of the heat-scaling component 22 is controlled to the preset value.

The heating component 11 is connected to the adjustment component 12, and the adjustment component 12 can drive the heating component 11 to move, thereby adjusting the relative position between the heating component 11 and the preheating mechanism 2. Since the workpiece to be welded is located on the preheating mechanism 2, by adjusting the position between the heating component 11 and the preheating mechanism 2, the position between the heating component 11 and the workpiece to be welded can be adjusted, thereby improving the stability of the heating component 11 in welding the workpiece to be welded.

The third driving member can drive the first driving member 121 to move in the X direction, thereby also driving the heating assembly 11 to move in the Y direction. By providing the third driving member, the positions of the heating assembly 11 and the preheating mechanism 2 can be adjusted in the Y direction.

[0062] The first drive element 121 can be a linear motor, a hydraulic cylinder, or an electric cylinder; the second drive element 122 can be a linear motor, a hydraulic cylinder, or an electric cylinder; and the third drive element can be a linear motor, a hydraulic cylinder, or an electric cylinder.

In other words, it can reduce the temperature difference at various positions on the upper end surface 217 of the base plate 21. The workpiece to be welded is placed on the upper end surface 217, so that the workpiece to be welded is heated more evenly, thereby avoiding spot welding and cold welding during welding, thereby improving welding quality.

[0066] In one embodiment, the heat-scaling component 22 may be a heat-scaling tube or a heat-scaling plate. The accommodating cavity 211 is a connected space, and the heat-scaling tube or the heat-scaling plate is disposed in the accommodating cavity 211 .

A partition plate is provided between the first accommodating cavity and the second accommodating cavity to separate the first accommodating cavity and the second accommodating cavity.
