[0026] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0027] In order to solve the technical problem that conventional diameter limiting devices in the prior art cannot provide production lines that meet the needs of photovoltaic welding ribbons and other wires, resulting in particles on the surface of the produced photovoltaic welding ribbons and other wires, this application proposes a diameter limiting device. During the production process, photovoltaic welding ribbons and other wires pass through the diameter limiting holes of the diameter limiting device to achieve control of process defects and prevent tin particles generated during the production of photovoltaic welding ribbons and other wires from being attached to the surface of the wire and flowing out, affecting the quality of the wire.

[0028] The diameter limiting device according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the diameter limiting device provided by the embodiment of the present invention includes a first body 10 and a second body 20, wherein the first body 10 and the second body 20 are connected in an openable and closable manner. The first body 10 has a first preset surface 11, and the second body 20 has a second preset surface 21. When the first body 10 and the second body 20 are in a closed state, the first preset surface 11 and the second preset surface 21 are in contact with each other. Figure 1 As shown, the first preset surface 11 is provided with a first slot 111, and the first slot 111 passes through the first preset surface 11, and the second preset surface 21 is provided with a second slot 211, and the second slot 211 passes through the second preset surface 21. Figure 2 As shown, when the first body 10 and the second body 20 are in the closed state, the first slot 111 and the second slot 211 cooperate to form a diameter-limiting hole. The size of the diameter-limiting hole is adapted to the wire to be produced. During the production process of the wire, the wire passes through the diameter-limiting hole, which can scrape off particles such as tin on the surface of the wire, preventing the surface of the wire from being contaminated with tin and other particles, which may affect the quality of the wire. It should be noted that in the embodiments of the present invention, the wire includes but is not limited to products such as photovoltaic welding ribbons.

[0030] Since the wire needs to pass through the diameter-limiting hole during the actual production process, please refer to Figure 1 As shown, the first body 10 and the second body 20 are in an open state, and then the first end of the wire is introduced and placed in the second slot 211, and the first end of the wire needs to pass through the second preset surface 21, and then the first body 10 and the second body 20 are closed, so that the first end of the wire is located in the diameter-limiting hole formed by the first slot and the second slot, and then the first end of the wire is pulled by the preset production equipment so that the wire passes through the diameter-limiting hole. Therefore, in an embodiment of the present invention, the first body 10 and the second body 20 are set to be openable and closable. It can facilitate the free switching of the first body 10 and the second body 20 between the open and closed states during the production process, reduce the time for placing the wire, and improve production efficiency.

[0031] Taking the photovoltaic welding ribbon as an example, since there are many specifications of photovoltaic welding ribbons, the wire diameters, shapes, etc. of photovoltaic welding ribbons of different specifications may be different. Therefore, photovoltaic welding ribbons of different specifications have different requirements for the diameter limiting holes of the diameter limiting device. Therefore, in actual production, when producing photovoltaic welding ribbons of different specifications, it is necessary to remove the original diameter limiting device and reinstall a new diameter limiting device that matches the photovoltaic welding ribbon to be produced, which requires frequent disassembly and installation of the diameter limiting device. In order to solve the above problem, as a preferred embodiment, in the embodiment of the present invention, the first slot 111 is provided to include a plurality of slots with different widths and / or depths, and the second slot 211 includes a plurality of slots with different widths and / or depths corresponding to the first slot. When the first main body 10 and the second main body 20 are closed, the first slot 111 cooperates with the second slot 211 to form a plurality of diameter limiting holes suitable for wires of different diameters to pass through. Further reference Figure 1 As shown, in an embodiment of the present invention, taking the example of the first slot 111 and the second slot 211 both including two slots with different radii, when the first body 10 and the second body 20 are closed, the first slot 111 cooperates with the second slot 211 to form two diameter-limiting holes with different radii, so that the diameter-limiting device can be applied to the production of two wires with different diameter limits, reducing the installation frequency of switching the diameter-limiting device according to product specifications, saving loading and unloading time, improving production efficiency, and reducing production costs. It should be noted here that in an embodiment of the present invention, there is no restriction on the width and / or depth of the first slot 111 and the second slot 211, and the user can set it according to actual production needs.

[0032] As a preferred embodiment, in an embodiment of the present invention, the diameter-limiting hole has at least one of the following shapes: a circle, an ellipse, a semicircle, a semicircle with a base portion extending outward on the bottom edge, a trapezoid, a triangle, or a triangle with a base portion extending outward on the bottom edge, wherein the two ends of the base portion may also have an arc shape, and the arc shape includes a superior arc and an inferior arc. It should be noted that the above shape is only an exemplary description and is not intended to limit the shape of the diameter-limiting hole. Users can set it according to actual production needs.

[0033] Further references Figure 1 As shown, as a preferred embodiment, in the embodiment of the present invention, at least one third slot 112 can be further provided on the first preset surface 11 of the first body 10, and at least one fourth slot 212 can be further provided on the second preset surface 21 of the second body 20, wherein the third slot 112 cooperates with the fourth slot 212. When the first body 10 and the second body 20 are in a closed state, the third slot 112 cooperates with the fourth slot 212 to form a cavity, which is used to accommodate waste materials such as tin ash scraped from the surface of the wire to prevent waste materials such as tin ash from accumulating and jamming the wire. It should be noted here that, in the embodiment of the present invention, the number of the third slot 112 and the fourth slot 212 can be set according to actual needs, and there is no restriction here. Figure 1 The fact that the number of the third slots 112 and the fourth slots 212 is set to 2 is only an exemplary description. In actual applications, the user can set the number of the third slots 112 and the fourth slots 212 according to actual production requirements.

[0034] Further references Figure 1 As shown, the third slot 112 is cross-arranged with the first slot 111, and the fourth slot 212 is cross-arranged with the second slot 211. This arrangement allows waste materials such as tin ash scraped from the surface of the wire to fall into the third slot 112 or the fourth slot 212, preventing waste materials such as tin ash from accumulating on the first preset surface 11 and the second preset surface 21, thereby causing problems such as wire jamming.

[0035] Further references Figure 1 As shown, in the embodiment of the present invention, the depth of the third slot 112 is set to be greater than the depth of the first slot 111, and the depth of the fourth slot 212 is set to be greater than the depth of the second slot 211. This arrangement allows the third slot 112 and the fourth slot 212 to accommodate more waste materials such as tin ash, preventing tin ash and other waste materials from overflowing the third slot 112 or the fourth slot 212 and accumulating on the first preset surface 11 and the second preset surface 21, thereby causing problems such as wire jamming.

[0036] As a preferred embodiment, in the embodiment of the present invention, the cross-sections of the third slot 112 and the fourth slot 212 are at least one of the following shapes: circular, semicircular, U-shaped, trapezoidal, triangular, rectangular, or square. It should be noted that the cross-sectional shapes of the third slot 112 and the fourth slot 212 can be the same or different, and the position of the third slot 112 on the first preset surface 11 and the position of the fourth slot 212 on the second preset surface 21 can be consistent or inconsistent. Users can set these according to actual production needs and are not limited here.

[0037] During the wire rod production process, waste materials such as tin ash accumulated in the third slot 112 and the fourth slot 212 can be promptly cleaned out using equipment such as an air gun, eliminating the need to remove the diameter limiting device. To facilitate the removal of waste materials such as tin ash from the third slot 112 and the fourth slot 212 using equipment such as an air gun, as a preferred embodiment, in this embodiment of the present invention, the width of the slot opening of the third slot 112 and the fourth slot 212 can be set to be greater than the width of the slot bottom.

[0038] As a preferred embodiment, in the embodiment of the present invention, the weight of the first body 10 is set to be greater than the weight of the second body 20. Figure 2 As shown, during use of the diameter limiting device, the first body 10 is located above the second body 20. Setting the weight of the first body 10 to be greater than the weight of the second body 20 can prevent the diameter limiting device from not closing due to the shaking of the wire passing through the diameter limiting hole, that is, preventing the first body 10 and the second body 20 from closing.

[0039] As a preferred embodiment, in the embodiment of the present invention, the first body 10 and the second body 20 are provided with strong magnetism. Figure 2 As shown, during use of the diameter limiting device, the first body 10 is located above the second body 20. Setting the first body 10 and the second body 20 to have strong magnetism can also prevent the diameter limiting device from not closing due to the shaking of the wire passing through the diameter limiting hole, that is, preventing the first body 10 and the second body 20 from closing.

[0040] As a preferred embodiment, in the embodiment of the present invention, a handle 13 is provided on the third preset surface 12 of the first body 10, and the third preset surface 12 is a different surface from the first preset surface 11. Figure 2 As shown, a handle 13 is provided on the first body 10, which can facilitate the user to separate or close the first body 10 and the second body 20 through the handle 13. The third preset surface 12 can be any surface of the first body 10 except the first preset surface 11.

[0041] Reference Figure 3 As shown, as a preferred embodiment, in the embodiment of the present invention, the first body 10 is provided with a first connecting portion 14, and the second body 20 is provided with a second connecting portion 24, wherein the first connecting portion 14 cooperates with the second connecting portion 24. Through the connection between the first connecting portion 14 and the second connecting portion 24, the first body 10 and the second body 20 can be connected in an openable and closable manner.

[0042] Further references Figure 3 As shown, as a preferred embodiment, in this embodiment of the present invention, the first connecting portion 14 includes a first connecting hole 141, and the second connecting portion 24 includes a second connecting hole 241, wherein the first connecting hole 141 cooperates with the second connecting hole 241. Through the pivotal connection between the first connecting hole 141 and the second connecting hole 241, an openable and closable connection between the first connecting portion 14 and the second connecting portion 24 can be achieved, thereby achieving an openable and closable connection between the first body 10 and the second body 20. It should be noted that in this embodiment of the present invention, in addition to being connected by a pivot, the first connecting hole 141 and the second connecting hole 241 can also be connected by hinges, bolts, etc., which will not be described in detail here.
