With the increase in coating speed, the length of the coating machine oven has also increased significantly. To ensure that the electrode sheet does not deviate during long-distance operation in the oven, a deviation rectifying device needs to be installed. However, for the high-temperature environment in the oven, the deviation rectifying actuators of the existing technologies cannot work in the high-temperature environment, thus making it impossible to implement.

[0030] This application provides an embodiment of a deviation rectifying device applied in an oven. For details, please refer to Figure 1 and Figure 3 .

[0031] The deviation rectifying device applied in the oven in this embodiment includes: a deviation rectifying device body for installation at the bypass of the pole piece 11 on the end face of the oven. The deviation rectifying device body includes a shield 01 and a deviation rectifying component arranged inside the shield 01. An air filter 05 for introducing ambient air to reduce the temperature of the deviation rectifying area is arranged on the shield 01.

[0032] It should be noted that: by utilizing the negative pressure principle of the inner cavity of the oven, ambient air is inhaled. Specifically, the ambient air enters the shield 01 through the air filter 05, cools the deviation rectifying component after passing through the deviation rectifying component area, so as to protect the deviation rectifying component from being damaged by high temperature, which can effectively solve the problem that the existing deviation rectifying device cannot work in the high-temperature environment in the oven, and thus complete the deviation rectifying work normally in the oven, ensuring that the pole piece 11 does not deviate during long-distance operation in the oven.

[0033] The above is the first embodiment of a deviation rectifying device applied to an oven provided by the embodiments of the present application. The following is the second embodiment of a deviation rectifying device applied to an oven provided by the embodiments of the present application. For details, please refer to Figures 1 to 4 。

[0034] The deviation rectifying device applied to an oven in this embodiment includes: a deviation rectifying device body for being installed at the bypass of the pole piece 11 on the end face of the oven. The deviation rectifying device body includes a shield 01 and a deviation rectifying component arranged inside the shield 01. An air filter 05 for introducing ambient air to reduce the temperature of the deviation rectifying area is arranged on the shield 01. Specifically, the shield 01 is a rectangular structure with one end open.

[0035] It can be understood that the deviation rectifying component generally works below 60°C. When the temperature exceeds 60°C, some components will be damaged. And the deviation rectifying component is placed inside the oven, and the temperature inside the oven is about 150°C. To avoid damage to the deviation rectifying component, the present application utilizes the negative pressure characteristic inside the oven, and an air filter 05 is arranged on the shield 01 to filter the ambient air at about 30°C. The ambient air enters the shield 01, passes through the deviation rectifying component and then enters the oven. By supplementing the ambient air, the high temperature in the deviation rectifying area is diluted to ensure that the deviation rectifying component can work normally.

[0036] The open side of the shield 01 is fixedly connected to the end face of the oven through a high-temperature heat insulation plate 10.

[0037] A support seat 02 is arranged at the bottom of the shield 01, and the support seat 02 is fixedly connected to the high-temperature heat insulation plate 10. Specifically, the support seat 02 is a triangular structure.

[0038] The deviation rectifying component includes a deviation rectifying sensor 07 for detecting whether the pole piece 11 runs off track, a deviation rectifying swing roller 06 for connecting with the pole piece 11, and a deviation rectifying actuator 03 for driving the deviation rectifying swing roller 06 to perform deviation rectifying actions. The deviation rectifying sensor 07 is electrically connected to the deviation rectifying actuator 03, and is used to control the deviation rectifying actuator 03 to perform corresponding deviation rectifying actions when detecting that the pole piece 11 runs off track. The deviation rectifying sensor 07 can be fixed on the side of the high-temperature heat insulation plate 10 close to the shield 01.

[0039] An eight-shaped track 04 is arranged on the inner bottom surface of the shield 01. Both ends of the deviation rectifying swing roller 06 are slidably connected to the eight-shaped track 04 through a connecting piece 09. The deviation rectifying actuator 03 is drivingly connected to the connecting piece 09 and is used to drive the connecting piece 09 to slide left and right on the eight-shaped track 04. Specifically, the deviation rectifying actuator 03 can be an electric push rod or a cylinder.

[0040] An operation door 08 is arranged on the shield 01, and an air filter 05 can also be arranged on the operation door 08 to increase the inflow of external ambient air.

[0041] During specific implementation, the electrode sheet 11 is dried by winding inside the oven. Normally, it runs in the middle of the rollers. However, the electrode sheet 11 may deviate during its operation inside the oven. Therefore, at the winding area on the end face of the oven, this deviation rectifying device is installed to prevent deviation. Specifically, the electrode sheet 11 is wound around the deviation rectifying swing roller 06, and the deviation rectifying sensor 07 is used to monitor in real time whether the electrode sheet 11 is running in the middle of the roller surface. Since the length of the roller is a bit wider than the electrode sheet 11, when the electrode sheet 11 deviates beyond the roller, the electrode sheet 11 will be torn. If the electrode sheet 11 is not running in the middle of the roller surface, the deviation rectifying sensor 07 will collect signals and send them to the deviation rectifying actuator 03, controlling the deviation rectifying actuator 03 to contract or push the deviation rectifying swing roller 06 on the eight-shaped track 04 to swing in the corresponding direction for straightening. During this process, the ambient air will enter through the air filter 05 on the shield 01 and pass through the deviation rectifying component area to prevent the high temperature inside the oven from spreading to the deviation rectifying area.

[0042] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
