Description

Technical Field

[0002] The coating machine uses an infrared plate assembly to bake the coated electrode. In the prior art, wires are used to directly weld the infrared plate to achieve electrical connection of the infrared plate, so that the infrared plate can radiate heat. However, on the one hand, because the temperature required for coating is very high (up to 400°C), when the infrared plate heats to a high temperature, the terminal head on the wire that is welded to the infrared plate is easily burned, resulting in abnormal electrical connection of the infrared plate. On the other hand, affected by the level of welding, the wire is prone to cold welding or leaking when welded to the infrared plate, resulting in abnormal electrical connection of the infrared plate. Therefore, the baking stability of the existing coating machine is poor. Utility Model Content

[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] The coating machine uses an infrared board assembly to bake the coated electrode. In the prior art, wires are used to directly weld the infrared board to achieve electrical connection of the infrared board, so that the infrared board can radiate heat. But on the one hand, because the temperature required for coating is very high (up to 400°C), when the infrared board heats to a higher temperature, the terminal heads on the wires that are welded to the infrared board are easily burned, resulting in abnormal electrical connection of the infrared board. Specifically, when the infrared board exceeds about 300°C, the terminal heads of the wires will appear burnt black. Therefore, the sintering heads need to be fixed with glue, but the glue cannot withstand high temperatures and will soften, resulting in loose pulling force of the terminal heads, which in turn leads to abnormal electrical connection of the infrared board. On the other hand, affected by the level of welding, the wires are prone to cold soldering or leaking when welded to the infrared board, resulting in abnormal electrical connection of the infrared board. Therefore, the baking stability of the existing coating machine is poor.

[0052] In view of this, the first embodiment of the utility model proposes a heating component 10, which is used in a coating machine. The heating component 10 has high baking stability. It should be noted that the heating component 10 can be an infrared panel component. Figures 1 to 10 The heating assembly 10 according to the embodiment of the present application is introduced. Specifically, the heating assembly 10 includes a first heating plate 100 , a spring 200 and a base frame 300 .

[0053] Reference Figures 1 to 3 , the first heating plate 100 can generate heat to bake the battery electrode. Specifically, the first heating plate 100 can be an infrared plate. The first heating plate 100 can generate radiation heat after the electrical connection is achieved. The specific configuration of the first heating plate 100 can refer to the relevant known technology.

[0054] Reference Figures 3 to 5 The spring sheet 200 is stacked and connected with the first heating plate 100 along the thickness direction Z thereof. Figure 3 The direction in is used as a reference, and the thickness direction Z may be the left-right direction. It can be understood that the spring piece 200 can be connected to the first heating plate 100 and then connected to the wire to achieve electrical connection of the first heating plate 100.

[0055] Reference Figures 1 to 4The base frame 300 is used to carry the spring sheet 200 and the first heating plate 100. Specifically, the base frame 300 can be arranged on the side of the spring sheet 200 away from the first heating plate 100. Figure 4 The orientation in is used as a reference, that is, the first heating plate 100 can be arranged on the upper side, the base frame 300 is arranged on the lower side, and the spring piece 200 is arranged between the first heating plate 100 and the base frame 300.

[0056] In the technical solution of the utility model, the heating assembly 10 includes a first heating plate 100, a spring 200 and a base frame 300. Compared with the technical solution of the prior art that uses a wire to weld directly to the heating plate, in this solution, the spring 200 is connected to the first heating plate 100 in a stacked manner along the thickness direction Z, and then the spring 200 is connected to the wire to achieve the electrical connection of the first heating plate 100. By adding the spring 200, the present solution can effectively avoid the phenomenon of the wire connecting the heating plate being burned, thereby ensuring the stability of the electrical connection of the first heating plate 100. Moreover, the present solution is not affected by the level of welding technology. Furthermore, the present solution uses a base frame 300 to carry the spring 200 and the first heating plate 100 to ensure the stability of the connection between the spring 200 and the first heating plate 100. In addition, compared with the technical solution that uses a wire to weld directly to the heating plate, the present solution only needs to replace the existing heating plate with a new infrared plate when it fails, and the overall maintenance operation is convenient and quick. In summary, this solution can effectively improve the baking stability of the heating component 10 and ensure that the coating machine can continue to operate normally.

[0057] At present, many coating widths are greater than 1200mm. Since infrared panels are generally made of glass as a carrier, large-area infrared panels are not easy to be directly processed and formed. Therefore, the existing technology uses multiple small infrared panels to splice into a large infrared panel to achieve production. However, multiple infrared panels need to be connected with multiple wires to achieve electrical connection and radiate heat. Therefore, the wiring of multiple infrared panels in the existing heating assembly is complicated.

[0058] Reference Figure 4 and Fig.10 , the following describes the specific configuration of the heating plate of the heating assembly 10 in some embodiments of the present application. It can be understood that referring to Fig. 9 , the heating plate of the heating assembly 10 can be set as a single one. Fig.10 The heating assembly 10 may also include multiple heating plates. In some embodiments of the present application, three heating plates are used as an example. It should be noted that when multiple heating plates are provided, each heating plate may be arranged in a staggered manner to avoid uneven heating (for the electrode after coating).

[0059] In order to facilitate the description and understanding of the specific arrangement of the multiple heating plates, a first direction X is defined. The first direction X is perpendicular to the thickness direction Z. Fig.10With reference to the orientation in , the thickness direction Z points to the front-to-back direction, and the first direction X points to the left-to-right direction.

[0060] Reference Figure 4 The heating assembly 10 includes a second heating plate 400 located on the side of the spring 200 away from the base frame 300, that is, the base frame 300 can simultaneously carry the first heating plate 100 and the second heating plate 400. The second heating plate 400 is stacked and connected with the spring 200 along the thickness direction Z. When the heating assembly 10 in this solution is provided with multiple heating plates, because the spring 200 is simultaneously connected to the first heating plate 100 and the second heating plate 400, when the electrical connection of each heating plate is made, it is only necessary to connect the wire to the spring 200. Therefore, this solution can effectively reduce the number of wire outlets and avoid the occurrence of cumbersome wiring.

[0061] Reference Figure 1 In some embodiments, the heating assembly 10 includes a first stopper 500, and the first stopper 500 can fix the first heating plate 100. Specifically, the first stopper 500 is disposed on the side of the first heating plate 100 that is away from the base frame 300, that is, the first heating plate 100 is located between the first stopper 500 and the base frame 300. In this solution, the first stopper 500 is connected to the base frame 300, that is, the first stopper 500 and the base frame 300 can jointly clamp the first heating plate 100 and the spring 200, which can effectively improve the stability of the connection between the first heating plate 100 and the spring 200, thereby improving the stability of the electrical connection of the first heating plate 100, and ensuring the stability of the baking of the heating assembly 10.

[0062] Reference Fig. 9 and Fig.10 The specific structure of the first stopper 500 is described below. The first stopper 500 includes a plurality of first bending portions 510 arranged at intervals. Fig.10 With reference to the orientation in , each first bending portion 510 can be arranged at intervals along the first direction X. Specifically, the intervals between each two adjacent first bending portions 510 can be uniformly spaced. It should be noted that in some embodiments, each first bending portion 510 can be arranged as an integral whole. In other embodiments, each first bending portion 510 can also be arranged separately. Some embodiments of the present application are described by taking the separate arrangement of each first bending portion 510 as an example. It can be understood that the first bending portion 510 can be an L-shaped plate, etc. In this solution, the first bending portion 510 abuts against the first heating plate 100, that is, it can limit the first heating plate 100 from detaching from the base frame 300 along the thickness direction Z, further improve the reliability of the connection between the first heating plate 100 and the spring 200, and ensure the stability of baking of the heating component 10.

[0063] Reference Figure 4 and Figure 5, the specific structure of the base frame 300 is introduced below. In some embodiments, the base frame 300 includes a receiving groove 310 facing the spring sheet 200, and the receiving groove 310 can be adapted to the spring sheet 200 to accommodate the spring sheet 200. Specifically, the receiving groove 310 can be directly opened on the base frame 300, or a plurality of bent plates can be arranged to enclose the receiving groove 310. Some embodiments of the present application are described by taking the arrangement of a plurality of bent plates to enclose the receiving groove 310 as an example.

[0064] Reference Figure 3 , the spring piece 200 can be at least partially accommodated in the accommodating groove 310, and the specific accommodating size of the spring piece 200 can be determined according to actual conditions. By setting the accommodating groove 310, this solution can limit the spring piece 200 from leaving the accommodating groove 310 along the first direction X, and the first direction X is perpendicular to the thickness direction Z. It should be noted that the first direction X can be any direction perpendicular to the thickness direction Z, so that Figure 3 With reference to the direction in FIG. 1 , some embodiments of the present application are described by taking the first direction X as the front-to-back direction as an example.

[0065] Reference Figure 3 and Figure 5 In some embodiments, the heating component 10 further includes a partition 600 , which may be a mica insulating board. The partition 600 can prevent the base frame 300 from being electrically connected to the spring 200 , thereby ensuring the safety of the heating component 10 .

[0066] The specific location of the partition 600 is described below. Figure 3 As a reference, the partition 600 is located between the spring sheet 200 and the base frame 300 along the left-right direction, that is, the partition 600 can separate the base frame 300 from the spring sheet 200. In addition, the partition 600 can be at least partially accommodated in the receiving groove 310, that is, the stability of the connection between the partition 600 and the base frame 300 can be improved.

[0067] It should be noted that the partition 600 can be connected with the spring sheet 200, that is, the stability of the connection between the base frame 300 and the spring sheet 200 can be ensured. Figure 5 In some embodiments, a first bending portion 230 may be provided on the side of the spring sheet 200 facing the partition 600, and the first bending portion 230 has a connection hole 231, and the connection hole 231 can be wired and conductive. A first slot body 610 may be provided on the side of the partition 600 facing the spring sheet 200, and the first slot body 610 is adapted to the arrangement of the first bending portion 230. The first bending portion 230 may be penetrated by the first slot body 610, so that the partition 600 can avoid the high-temperature wiring portion of the first bending portion 230. Further, the base frame 300 may be provided with an avoidance groove 320, and the first bending portion 230 may be penetrated by the avoidance groove 320, so that the base frame 300 can avoid the high-temperature wiring portion of the first bending portion 230.

[0068] In other embodiments, a second bending portion 240 may also be provided on the side of the spring clip 200 facing the partition 600, a second groove body 620 may be provided on the side of the partition 600 facing the spring clip 200, and the second bending portion 240 may pass through the second groove body 620, that is, the partition 600 can limit the spring clip 200, and can improve the stability of the connection between the spring clip 200 and the base frame 300.

[0069] Reference Figures 4 to 6 The specific structure of the spring sheet 200 is described below. In some embodiments, the spring sheet 200 includes a base 210 and a plurality of elastic bosses 220. Specifically, the elastic bosses 220 can be arranged on a side of the base 210 facing the first heating plate 100. The elastic bosses 220 are arranged on the base 210 at intervals along the first direction X so as to Figure 7 The orientation in is used as a reference, that is, each elastic boss 220 can be arranged on the base 210 at uniform intervals along the left-right direction. The elastic boss 220 can be elastically deformed to connect to the first heating plate 100. This solution can avoid the disconnection between the spring piece 200 and the first heating plate 100 when the coating machine vibrates, thereby ensuring the stability of the electrical connection of the first heating plate 100. In addition, the elastic boss 220 of the spring piece 200 in this solution can also alleviate the effect of the thermal expansion of the first heating plate 100. It should be noted that the elastic boss 220 can be silver-plated, so as to further improve the stability of the conductive contact between the spring piece 200 and the first heating plate 100.

[0070] Reference Figure 7 and Figure 8 , the specific location of the elastic boss 220 in the spring sheet 200 on the base 210 is described below.

[0071] Specifically, the base 210 includes a first side 211 and a second side 212 arranged opposite to each other along the second direction Y. In some embodiments, not shown in the drawings, the elastic boss 220 may be connected to the first side 211 and spaced apart from the second side 212. Figure 7 The elastic boss 220 is connected to the second side 212 and is spaced apart from the first side 211. This solution can prevent the excess portion of the elastic boss 220 from being in contact with the first heating plate 100 and being burned. Figure 8The elastic boss 220 is disposed between the first side edge 211 and the second side edge 212, and is spaced apart from the first side edge 211 and the second side edge 212.

Fig.10 With reference to the orientation in , the thickness direction Z may point to the front-to-back direction, the first direction X may point to the left-to-right direction, and the second direction Y may point to the up-down direction.

[0073] Reference Fig. 9 and Fig.10 The specific structure of the second stopper 700 is described below. The second stopper 700 includes a plurality of second bending portions 710 arranged at intervals. Fig.10 With reference to the orientation in the figure, each second bending portion 710 can be arranged at intervals along the first direction X.
