[0025] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.
[0026] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.
[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0029] In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and cannot be understood as limiting the scope of protection of this application.

In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.
[0030] Figure 1 It is a structural schematic diagram of a coating oven device provided in one embodiment of the present application.
[0031] like Figure 1 The coating oven device 100 includes an unwinding mechanism 1, a first electrode piece splicing platform 2, an oven device 3 and a second electrode piece splicing platform 4 which are placed in sequence. The oven device 3 is composed of a plurality of oven sections 30 connected in series. An inlet 31 for the electrode piece 5 to pass through is provided on the left side of the oven device 3. An outlet 32 for the electrode piece 5 to pass through is provided on the right side of the oven device 3. An oven traction mechanism 6 is provided between the first electrode piece splicing platform 2 and the oven device 3. The oven traction mechanism 6 includes a connecting portion 61 and a traction portion 62. The connecting portion 61 is fixedly connected to the inlet 31 of the oven device 3, and the traction portion 62 is configured to pass through the interior of the oven device 3. The unwinding mechanism 1 includes a traction belt 10, which is configured to carry the electrode piece 5 and drive the electrode piece 5 to move. One end of the traction belt 10 is connected to the connecting portion 61 to transport the electrode piece 5.
[0032] When the coating oven device 100 is running, the electrode piece 5 is configured to be connected to the traction belt 10 on the first electrode piece splicing platform 2. Subsequently, the traction belt 10 carries the electrode piece 5 and drives the electrode piece 5 to move to the entrance 31 of the oven device 3. The electrode piece 5 is connected to the traction part 62 via the connecting part 61. Subsequently, the electrode piece 5 is moved out from the outlet 32 of the oven device 3 to the second electrode piece splicing platform 4 under the driving action of the traction part 62.
[0033] When the pole piece 5 is broken in the oven device 3, the broken pole piece 5 can be moved out from the outlet 32 of the oven device 3 to the second pole piece splicing platform 4 under the driving action of the traction part 62. At this time, the broken pole piece 5 can be re-spliced on the second pole piece splicing platform 4 for subsequent coating. Therefore, personnel no longer need to manually pull out the pole piece 5 in the oven device 3, avoiding burns. In addition, the traction belt 10 plays a bearing and driving role for the part of the pole piece 5 that has not entered the oven device 3. When the pole piece 5 is broken, it can act as a buffer to avoid dislocation of the pole piece surface, thereby reducing the risk of secondary breakage.
[0034] For the traction portion 62, if Figure 2 In some embodiments, the traction portion 62 includes a traction track 621 disposed on the inner wall of the oven device 3. The traction track 621 is configured to penetrate through the outlet 32 of the oven device 3. The connecting portion 61 can slide in the traction track to drive the pole piece 5 to move out of the outlet 32 smoothly.
[0035] For the connecting portion 61, Figure 3 In some embodiments, the connecting portion 61 includes a traction beam 611. The bottom of the traction beam 611 is embedded in the traction rail 621 to remain fixed in the oven device 3. The traction beam 611 is configured to fix the traction belt 10 so that the force of the traction belt 10 is stable. Figure 3 , the traction beam 611 can be extended and placed along the moving direction of the pole piece 5. The traction beam 611 is provided with a pressure strip 612 that can be placed along the moving direction of the pole piece 5. There are two pressure strips 612, each of which is fixedly connected to the traction beam 611 through a telescopic spring. The pressure strip 612 is configured to clamp the traction belt 622. In this way, the pressure strip 612 can clamp the traction belt 10, and the pole piece 5 moves toward the outlet 32 under the traction action of the traction belt 10, thereby avoiding the risk of damage that may be caused by directly pulling the pole piece 5, and also avoiding the surface of the traction belt 10 from sagging and wrinkling, reducing the risk of secondary belt breakage.
[0036] In some embodiments, the moving direction of the pole piece 5 can be controlled by a motor 7 disposed inside the oven device 3. For example, the pole piece 5 is controlled to move from the inlet 31 to the outlet 32 inside the oven device 3, or the pole piece 5 is controlled to move from the outlet 32 to the inlet 31 inside the oven device 3.
[0037] In some embodiments, the traction belt 10 may be made of a high temperature resistant material to prevent the surface of the traction belt 10 from melting when passing through the oven device 3, thereby reducing the risk of secondary belt breakage.
[0038] It can be seen from the above description that when the pole piece 5 is broken in the oven device 3, the pole piece 5 is driven through the oven device 3 by the oven traction mechanism 6, so that the broken pole piece 5 can be transported to the second pole piece splicing platform 4 inside the oven device 3, so that personnel can complete the splicing of the pole piece 5 outside the oven to avoid burns. In addition, the oven traction mechanism 6 can buffer the force of the broken pole piece 5, avoid the surface dislocation of the pole piece due to uneven force, and thus reduce the risk of secondary pole piece breakage.
[0039] Figure 4 It is a structural schematic diagram of a coating system 200 provided in one embodiment of the present application.
[0040] like Figure 4 The coating system 200 includes a die head 8 and a coating oven device 100. The die head 8 is disposed behind the second pole piece splicing platform 4. When the broken pole piece 5 is re-spliced at the second pole piece splicing platform 4, the die head 8 can perform subsequent coating operations on the spliced pole piece 5.
