At present, when tinning the wire (such as photovoltaic welding strip), the tinning tool will contact the wire, and carbon deposits will form on the surface after a period of use (usually about 8 hours). In order to ensure product quality, it is necessary to use tools to disassemble the tinning tool and polish the surface before installing and using it. However, on the one hand, disassembling the tool requires lifting the tool module bracket above the tin surface, which is a time-consuming and labor-intensive process; on the other hand, disassembling the tool requires stopping the machine, which reduces product productivity.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of the present application.

[0027] As described in the background technology, in the related art, the tin coating tooling 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 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.

[0028] In order to solve one or more of the above-mentioned technical problems of the related technology, 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 11 by setting a tool body 1. The plurality of working areas 11 can be switched through a switching module 2, thereby replacing the contact surface between the tool body 1 and the wire, thereby reducing the accumulation and formation of carbon deposits, and extending the service life of the tinning auxiliary mechanism. No manual operation or tool replacement is required during use.

[0029] The following is combined with Figure 1-3 The tin coating auxiliary mechanism of the photovoltaic solder strip in the embodiment of the present application is described in detail.

[0030] The tinning auxiliary mechanism of the wire provided in the embodiment of the present application is as follows: Figure 1 As shown, the wire tinning auxiliary mechanism provided in the embodiment of the present application generally includes a tool body 1, a switching module 2 and a fixed plate 3, wherein the switching module 2 is used in conjunction with the tool body 1, and the tool body 1 includes a plurality of working areas 11, and the plurality of working areas 11 can be switched through the switching module 2, so that the switching of the working areas 11 can be realized without stopping the machine, saving the time for disassembly and grinding. The fixed plate 3 is provided with a number of mounting holes of different specifications (not shown in the figure), and the tool body 1 can be mounted on the fixed plate 3 through a corresponding connection structure, and then the fixed plate 3 can be mounted on the tinning equipment through a connection structure such as a bolt connection, so that the tool body 1 can be easily rotated relative to the fixed plate 3, and at the same time, the working area 11 can be prevented from moving during the operation of the equipment, resulting in product defects such as uneven tinning of the produced wire.

[0031] It should be noted here that the shapes of the multiple working areas 11 and the shape of the tooling body 1 composed of the multiple working areas 11 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 11 and the tooling body 1 composed of the multiple working areas 11 in the embodiment of the present application. Preferably, in the embodiment of the present application, the shape of the tooling body 1 composed of the multiple working areas 11 is disc-shaped, and correspondingly, the shape of the working areas 11 constituting the tooling body 1 is fan-shaped.

[0032] It is understandable that the multiple working areas 11 can be integrally formed to form the tooling body 1, or the tooling body 1 can be formed by multiple independent working areas 11. The specific implementation method can be set according to actual production needs and is not limited here.

[0033] The following description is made by taking the tool body 1 being in a disc shape as an example. It can be understood that the tool body 1 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 1 of the present application.

[0034] In the embodiment of the present application, there is no limit on the number of working areas 11, and the specific number can be set according to actual needs. Taking the tool body 1 as a disc and the working area 11 as a fan, the number of working areas 11 is preferably 4, that is, the central angle of each working area 11 is 90°.

[0035] Further references Figure 1 As shown, each working area 11 at least includes a passage groove 111 for the wire to be processed to pass through, and the passage groove 111 is in contact with the wire to be processed. When the working area 11 is fan-shaped, the passage groove 111 is opened on the arc surface of the fan, that is, the passage groove 111 is opened along the circumference of the tooling body 1. In the embodiment of the present application, there is no specific limitation on the specific shape and size of the passage groove 111, which can be set according to actual needs. Preferably, the shape and size of the passage groove 111 are compatible with the shape and size of the wire to be processed so that the wire to be processed can pass through it. As a preferred embodiment, in the embodiment of the present application, the cross-section of the passage groove 111 can be at least one of the following shapes: circular, elliptical, semicircular. Among them, the wire to be processed includes but is not limited to products such as photovoltaic welding strips.

[0036] Further references Figure 1 and Figure 2 As shown, in the embodiment of the present application, the tooling body 1 and the fixing plate 3 are connected through the tooling fixing shaft 12, and the fixing plate 3 is provided with a fixing hole (not shown) for the tooling fixing shaft 12 to pass through; a step and an elastic member (not shown) are provided in the fixing hole for fixing the tooling fixing shaft 12 to prevent the tooling fixing shaft 12 from moving. The elastic member in the present embodiment is a retaining spring. One end of the tooling fixing shaft 12 is connected to the tooling body 1, and the other end of the tooling fixing shaft 12 is connected to the second transmission gear 213. In the embodiment of the present application, the second transmission gear 213 is a bevel gear.

[0037] The transmission assembly 21 includes an adjusting rod 211, which is connected to the fixing plate 3 through a mounting bracket 5; the mounting bracket 5 is connected to a flange sleeve 51 and a positioning ring 52, which are used to position the adjusting rod 211 when it is installed. One end of the adjusting rod 211 is connected to a first transmission gear 212 meshing with the second transmission gear 213. In this embodiment, the first transmission gear 212 is a bevel gear; the other end of the adjusting rod 211 is connected to a driving member 22 through a coupling. The driving member 22 in the embodiment of the present application is a servo motor, which can be controlled to rotate by a PLC output signal. By setting the PLC program, the driving member 22 can be controlled to drive the tooling body 1 to rotate a certain number of times at regular intervals; specifically, the PLC outputs a signal to the driving member 22, the driving member 22 starts, and then drives the meshing first transmission gear 212 and The second transmission gear 213 rotates to convert the rotational force of the Y-axis into the rotational force of the X-axis (in this embodiment, the Y-axis direction is the direction from the driving member 22 to the first transmission gear 212, and the X-axis direction is the direction from the second transmission gear 213 to the tool body 1;) thereby driving the tool body 1 to rotate to achieve switching of different working areas 11, so that the contact surface between the tool body 1 and the wire to be processed can be switched in time, resulting in the inability to form carbon deposits in the passage groove 111 in the tool body 1 that should have been formed within a certain period of time, thereby extending the service life of the tool body 1, reducing the adjustment frequency of the technicians, and eliminating the need for manual operation within a certain period of time.

The wire to be processed is wound in the feeding assembly, and after being tinned by the tinning mechanism, it passes through the working area 11 of the tinning auxiliary mechanism for the wire, and then enters the winding assembly for winding. The specific process is the prior art and will not be repeated here.
