[0027] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] As described in the background technology, the tin coating tooling in the prior art will form carbon deposits after being used for a period of time (usually about 8 hours). In order to ensure product quality, it is necessary to use tools to disassemble the tin coating tooling and polish the surface before installing it. However, on the one hand, disassembling the tooling requires lifting the tooling module bracket above the tin surface, which is a time-consuming and labor-intensive process. On the other hand, disassembling the tooling requires downtime, which reduces product productivity.

[0029] In order to solve one or more of the above-mentioned technical problems in the prior art, the present application creatively proposes a new tinning auxiliary mechanism for wires. The tinning auxiliary mechanism is configured to include a plurality of working areas in the tooling body, and the plurality of working areas can be switched through a positioning mechanism. This not only saves the time for disassembly and polishing, improves production efficiency, but also reduces downtime, thereby reducing the defects caused by each cold start and improving production efficiency.

[0030] The photovoltaic welding tape winding auxiliary device of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0031] The tinning auxiliary mechanism of the wire provided in the embodiment of the present application is as follows: Figure 1 and Figure 2 As shown, the tinning auxiliary mechanism of the wire provided in the embodiment of the present application generally includes a tool body 100, a positioning mechanism 200 and a fixed plate 300, wherein the positioning mechanism 200 is used in conjunction with the tool body 100, and the tool body 100 includes a plurality of working areas 110, and the plurality of working areas 110 can be switched through the positioning mechanism 200, so that the switching of the working areas 110 can be realized without stopping the machine, saving the time for disassembly and grinding. A connecting structure (not shown) is provided on the fixed plate 300, and the connecting structure (not shown) is connected to the tool body, and the connecting structure may include two groups, wherein one group of connecting structures is connected to the tool body, so that the tool body can rotate relative to the fixed plate 300, so as to facilitate the switching between multiple working areas, and the other group of connecting structures is connected to the tool body after the tool body is switched to the currently required working area, so that the currently required working area is fixed at the current position, so as to prevent the working area from moving during the working process, resulting in problems such as defective wire produced.

[0032] It should be noted here that the shapes of the multiple working areas and the shape of the tooling body composed of the multiple working areas are not specifically limited in the embodiment of the present application. Without violating the inventive concept of the present application, any shape can be used for the multiple working areas and the tooling body composed of the multiple working areas in the embodiment of the present application. In order to facilitate the rotation of the tooling body relative to the fixed plate 300, thereby facilitating the switching between the multiple working areas, in the embodiment of the present application, the shape of the tooling body composed of the multiple working areas is preferably disc-shaped, and correspondingly, the shape of the working areas of the tooling body is preferably fan-shaped.

[0033] It can be understood that multiple working areas can be integrally formed to form a tooling body, or multiple independent working areas can be interconnected to form a tooling body. The specific implementation method can be set according to actual production needs and is not limited here.

[0034] The following descriptions are all made by taking the tool body being in a disc shape as an example. It can be understood that the tool body being in a disc shape is an exemplary but not restrictive description and does not constitute a limitation on the shape of the tool body of the present application.

[0035] In the embodiment of the present application, there is no limit on the number of working areas, and the specific number can be set according to actual needs. Taking the tool body as a disc and the working area as a sector as an example, the number of working areas is preferably 4, that is, the central angle of each working area is 90°.

[0036] Further references Figure 1 and Figure 2 As shown, each working area 110 includes at least a slot 111, and the slot 111 is used for the wire to be processed to pass through and contact the wire to be processed. When the working area 110 is fan-shaped, the slot 111 is opened on the arc surface of the fan, that is, the slot 111 is opened along the circumference of the tooling body. In the embodiment of the present application, there is no specific limitation on the specific shape and size of the slot 111, which can be set according to actual needs. Preferably, the shape and size of the slot 111 are adapted to the shape and size of the wire to be processed so that the wire to be processed passes through it. As a preferred embodiment, in the embodiment of the present application, the slot 111 can be at least one of the following shapes: circular, elliptical, semicircular, with a base portion extending outward on the bottom edge of the semicircle, a trapezoidal, triangular, or a base portion extending outward on the bottom edge of the triangle. Among them, the wire to be processed includes but is not limited to products such as photovoltaic welding strips.

[0037] As a preferred implementation, in the embodiment of the present application, a positioning port 112 is also provided on the side of each work area 110, and the positioning port 112 matches the positioning mechanism. When the work area is switched by the positioning mechanism, the tooling is rotated locally. When the positioning mechanism is stuck in the positioning port 112 of the currently required work area 110, it means that the currently required work area 110 has reached the working position. At this time, the work area 110 is connected to the connection structure provided on the fixed plate 300, thereby fixing the work area so that its position will not move. The setting of the positioning port 112 can reduce the dependence on the skills of the debugging personnel and ensure the accuracy of the switching position.

[0038] Further references Figure 1 and Figure 2As shown, in the embodiment of the present application, the tooling body and the fixed plate 300 can be connected by a connecting rod. In specific implementation, the connecting rod includes a first connecting rod 310 and a second connecting rod 320, the first connecting rod 310 is used to fix the working area to the working position, and the second connecting rod 320 is used to allow the tooling body 100 to rotate relative to the fixed plate 300, so as to switch the position of the working area. Correspondingly, each working area 110 is provided with a first connecting hole 113 corresponding to the first connecting rod 310, and the first connecting hole 113 is axially opened on each working area 110. It can be understood that the connection structure on the fixed plate 300 also includes a connecting hole corresponding to the first connecting rod 310, so that the working area and the fixed plate 300 can be connected by the first connecting rod. In order to improve the stability of the connection between the working area and the fixed plate 300, the number of the first connecting rod 310 and the first connecting hole 113 can include multiple, preferably, the number of the first connecting rod 310 and the first connecting hole 113 are both 2. Since the second connecting rod 320 is used to allow the tool body 100 to rotate relative to the fixed plate 300, it is convenient to switch the position of the working area, and the second connecting hole (not shown in the figure) corresponding to the second connecting rod 320 can be opened at the center of the tool body 100, and the number of the second connecting rod 320 and the second connecting hole is one. When the tool body 100 is disc-shaped, the second connecting hole (not shown in the figure) can be opened at the center of the tool body 100. It can be understood that the connection structure on the fixed plate also includes a connection hole corresponding to the second connecting rod 320, so that the tool body and the fixed plate can be connected through the second connecting rod, and the tool body can rotate relative to the fixed plate after connection.

[0039] It can be understood that the second connecting rod 320 and the second connecting hole (not shown in the figure) are always connected, while the first connecting rod 310 and the first connecting hole 113 are not connected during the working area switching process. When switching to the required working area and the positioning mechanism is locked in the positioning port 112, the first connecting rod 310 and the first connecting hole 113 are connected, so that the position of the current working area is fixed and no longer moves.

[0040] It should be noted here that in the embodiment of the present application, there is no limitation on the specific connection method between the first connecting rod 310 and the first connecting hole 113 and the second connecting rod 320 and the second connecting hole (not shown in the figure), which can be one of the methods such as magnetic connection, snap connection, and threaded connection.

[0041] Further references Figure 1As shown, the positioning mechanism 200 generally includes a main body 210, a positioning rod 220 and an elastic connector 230. The main body 210 is fixedly connected to a tin coating device (not shown), and the elastic connector 230 is used to connect the positioning rod 220 and the main body 210. One end of the positioning rod 220 matches the positioning port 112.

[0042] As a preferred implementation mode, in the embodiment of the present application, the main body 210 is U-shaped, including a U-shaped opening, one end of the positioning rod 220 and the elastic connecting member 230 are both arranged in the U-shaped opening, and one end of the positioning rod 220 is connected to the U-shaped opening through the elastic connecting member 230.

[0043] As a preferred implementation, in the embodiment of the present application, the positioning rod 220 is T-shaped, and includes a first portion 221 and a second portion 222, and the first portion 221 and the second portion 222 are arranged in a T-shape. In specific implementation, the first portion 221 is connected to the U-shaped opening of the main body 210 through an elastic connector 230, one end of the second portion 222 is connected to the first portion 221, and the other end of the second portion 222 is used to be clamped in the positioning port 112.

[0044] As a preferred implementation, in the embodiment of the present application, the elastic connector 230 includes but is not limited to a spring, etc. The elastic connector 230 can connect the positioning rod 220 to the main body 210 on one hand, and on the other hand, can generate an elastic force between the positioning rod 220 and the main body 210 to move the two away from each other, so that a section of the second portion 222 of the positioning rod 220 can be stuck in the positioning port 112, and the two do not separate.

[0045] When the working area is switched by the positioning mechanism, the connection between the second connecting rod 320 and the second connecting hole (not shown in the figure) is maintained, the first connecting rod 310 is separated from the first connecting hole 113, and then the tooling body 100 is rotated to change the position of each working area 110. When a section of the second part 222 of the positioning rod 220 of the positioning mechanism 200 enters the positioning port of the currently required working area 110, the second part 222 of the positioning rod 220 will be temporarily fixed in the positioning port 112 due to the elastic force generated by the elastic connecting member 230, indicating that the currently required working area 110 has reached the working position. At this time, the second connecting rod 320 is connected to the second connecting hole (not shown in the figure) and the corresponding connecting structure on the fixing plate 300, so that the currently required working area 110 is fixed to the current working position to prevent the working area 110 from moving during the production process, thereby causing problems such as defective products.

[0046] Corresponding to the above-mentioned wire tinning auxiliary mechanism, the present application also provides a wire tinning device, the device includes an unwinding mechanism, a tinning mechanism, the wire tinning auxiliary mechanism as described above, and a winding mechanism, which are sequentially arranged along the running direction of the wire to be processed. The wire to be processed is wound in the unwinding mechanism, and after being tinned by the tinning mechanism, it passes through the working area of ​​the wire tinning auxiliary mechanism, and then enters the winding mechanism for winding. The specific process is not described one by one, and the user can set it according to needs.
