Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell electroplating technology, and in particular to a conductive device and photovoltaic cell electroplating equipment. Background Technology

[0002] Electroplating technology, as a novel electrode preparation method for photovoltaic cells, is being studied more and more extensively. As a promising electrode preparation method, electroplating can not only significantly reduce the cost of photovoltaic cell manufacturing processes, but also produce electrodes with higher aspect ratios and better conductivity compared to electrodes prepared by traditional screen printing. These electrodes also have lower internal resistance and reduce shading losses, thereby effectively improving the photoelectric conversion efficiency of photovoltaic cells.

[0003] In related technologies, photovoltaic cell electroplating equipment typically includes an electroplating tank and a power supply. The electroplating tank contains an electroplating solution, and an anode conductive element connected to the positive terminal of the power supply is usually installed inside the tank. A cathode conductive element connected to the negative terminal of the power supply is installed above the electroplating tank. During electroplating, the photovoltaic cell to be electroplated comes into contact with the cathode conductive element, forming a closed circuit with the anode conductive element, thereby depositing a coating on the surface of the photovoltaic cell. The cathode conductive element and the power supply in the photovoltaic cell electroplating equipment are usually connected by a mercury rotary joint. Because the rotating shaft comes into contact with the mercury inside the mercury rotary joint, the rotating shaft of the mercury rotary joint is prone to jamming during long-term use, causing the photovoltaic cell electroplating equipment to malfunction and resulting in poor reliability.

The first conductive clamping part 31 and the second conductive clamping part 32 are spaced apart to form a clamping cavity 30 for clamping the cathode conductive element 200.

[0033] In this embodiment of the invention, the conductive device 100 is used to connect the power cathode and the cathode conductive component 200 of the photovoltaic cell electroplating equipment, thereby achieving an electrical connection between the power cathode and the cathode conductive component 200 of the photovoltaic cell electroplating equipment. Specifically, the conductive body 1 is connected to the power cathode of the photovoltaic cell electroplating equipment. The conductive body 1 contacts the cathode conductive component 200 through a first conductive clamping part 31 and a second conductive clamping part 32, thus achieving an electrical connection between the power cathode and the cathode conductive component 200 of the photovoltaic cell electroplating equipment. The cathode conductive component 200 can be a component that directly contacts and conducts electricity with the photovoltaic cell, or it can be a component that indirectly contacts and conducts electricity with the photovoltaic cell. For example, when the cathode conductive component 200 is a component that directly contacts and conducts electricity with the photovoltaic cell, it can be a conductive rod that directly contacts the photovoltaic cell; or, for another example, when the cathode conductive component 200 is a component that indirectly contacts and conducts electricity with the photovoltaic cell, it can be a connecting rod connecting the conductive device 100, with the connecting rod connected to the conductive rod, and the connecting rod conducting electricity through contact with the photovoltaic cell.

[0034] In this embodiment of the invention, the clamping mechanism 3 is used to clamp the cathode conductive element 200, which is electrically connected to the power cathode of the photovoltaic cell electroplating equipment through the conductive device 100. The clamping mechanism 3 includes a first conductive clamping part 31 and a second conductive clamping part 32 arranged at intervals. The first conductive clamping part 31 and the second conductive clamping part 32 are arranged at intervals to form a clamping cavity 30, allowing the cathode conductive element 200 to be rotatably clamped between the first conductive clamping part 31 and the second conductive clamping part 32. Furthermore, the cathode conductive element 200 can rotate around the central axis L of the clamping cavity 30, achieving good electrical connection between the cathode conductive element 200 and the conductive device 100 during rotation.

[0035] The present invention provides a conductive device 100 that connects to a power source by providing a conductive body 1 and a clamping mechanism 3 connected to the conductive body 1. The clamping mechanism 3 includes a first conductive clamping part 31 and a second conductive clamping part 32 arranged at intervals. A clamping cavity 30 for clamping a cathode conductive element 200 is formed between the first conductive clamping part 31 and the second conductive clamping part 32. The conductive body 1 is connected to a power source, and the cathode conductive element 200 is clamped by the first conductive clamping part 31 and the second conductive clamping part 32, so that the cathode conductive element 200 is rotatably clamped between the first conductive clamping part 31 and the second conductive clamping part 32. Between the clamping parts 32, a good electrical connection can be maintained between the cathode conductive element 200 and the conductive device 100 during the rotation process, realizing a good electrical connection between the cathode conductive element 200 and the power cathode. The conductive device 100 replaces the traditional mercury rotary joint, which can avoid the jamming problem that is prone to occur when using a mercury rotary joint, and ensures a reliable electrical connection between the power supply and the cathode conductive element 200. Compared with the mercury rotary joint, the conductive device of this application can achieve a good electrical connection between the cathode conductive element and the power cathode, and is less prone to jamming problems, thereby improving the working reliability of the photovoltaic cell electroplating equipment.

[0036] As one embodiment of this utility model, the conductive body 1 includes:

[0037] Fixing part 11; and

[0038] Two wiring portions 12 connected to the fixing portion 11, the first conductive clamping portion 31 and the second conductive clamping portion 32 are respectively connected to one wiring portion 12.

[0039] In this embodiment, the fixing part 11 is used to fix the conductive device 100.

The two wiring parts 12 are used to connect the cathode of the power supply, thereby electrically connecting the power cathode and the cathode conductive element 200 of the photovoltaic cell electroplating equipment through the conductive device 100. In some other embodiments, the first conductive clamping part 31 and the second conductive clamping part 32 can also be connected to the fixing part 11. Figures 1-3 The first conductive clamping part 31 and the second conductive clamping part 32 shown in the diagram are both fixedly connected to the wiring part 12.

[0040] The two wiring portions 12 are respectively connected to the power cathode via cables, and the first conductive clamping portion 31 and the second conductive clamping portion 32 are respectively connected to one wiring portion 12, so that the first conductive clamping portion 31 and the second conductive clamping portion 32 maintain good electrical contact with the cathode conductive element 200, which helps to further improve the stability of the electrical contact between the first conductive clamping portion 31 and the second conductive clamping portion 32 and the cathode conductive element 200.

Specifically, the fixing part 11 can be tightly fitted with the fixing shaft on the bracket of the photovoltaic cell electroplating equipment through the mounting hole 110, so that the fixing part 11 is fixed on the bracket of the photovoltaic cell electroplating equipment and the photovoltaic cell electroplating equipment remains fixed during the electroplating process.

[0043] As an embodiment of this utility model, each wiring part 12 is provided with a wiring hole 121, and the wiring hole 121 is connected to the cathode of the power supply through a cable.

[0044] In this embodiment, each of the two wiring sections 12 is provided with a wiring hole 121 to facilitate connection of the wiring section 12 to the power supply via a cable. The wiring hole 121 on each wiring section 12 is connected to the power supply cathode via a cable, thereby achieving electrical connection between the wiring section 12 and the power supply cathode.

[0045] As an embodiment of the present invention, the two wiring portions 12 are bent relative to the fixing portion 11, and the wiring portions 12 and the fixing portion 11 form a cavity 111 that communicates with the clamping cavity 30.

[0046] In this embodiment, the two wiring portions 12 are bent relative to the fixing portion 11. The two wiring portions 12 and the fixing portion 11 can be arranged perpendicularly or non-perpendicularly. Optionally, the included angle between the wiring portions 12 and the fixing portion 11 is 60° to 100°. More preferably, the two wiring portions 12 are arranged perpendicularly to the fixing portion 11.

[0047] In this embodiment, since the two wiring portions 12 are bent relative to the fixing portion 11, and the wiring portions 12 and the fixing portion 11 form a cavity 111 that communicates with the clamping cavity 30, since the first conductive clamping portion 31 and the second conductive clamping portion 32 are respectively connected to a wiring portion 12, and since the design of the cavity 111 can increase the elastic deformation capability of the first conductive clamping portion 31 and the second conductive clamping portion 32, it is beneficial to clamp the cathode conductive element 200 more stably; moreover, it is beneficial to allow the cathode conductive element 200 to partially extend into the cavity 111, so that the conductive device 100 can clamp cathode conductive elements 200 of different lengths.

[0048] As an embodiment of the present invention, the first conductive clamping part 31 includes a plurality of first conductive springs 310 spaced apart, and the second conductive clamping part 32 includes a plurality of second conductive springs 320 spaced apart. The plurality of first conductive springs 310 and the plurality of second conductive springs 320 are spaced apart to form a clamping cavity 30.

[0049] In this embodiment, the first conductive clamping part 31 includes a plurality of first conductive springs 310 spaced apart, and the second conductive clamping part 32 includes a plurality of second conductive springs 320 spaced apart. The number of spaced-apart first conductive springs 310 in the first conductive clamping part 31 is not limited; for example, the first conductive clamping part 31 may have 2 to 6 first conductive springs 310. The number of spaced-apart second conductive springs 320 in the second conductive clamping part 32 is also not limited; for example, the second conductive clamping part 32 may have 2 to 6 second conductive springs 320. The number of first conductive springs 310 and second conductive springs 320 may be the same or different. Preferably, the number of first conductive springs 310 and second conductive springs 320 is the same, and the first conductive springs 310 and second conductive springs 320 are arranged opposite each other.

[0050] In this embodiment, the use of multiple first conductive springs 310 can increase the elastic deformation capability of the first conductive clamping part 31, and the use of multiple second conductive springs 320 can increase the elastic deformation capability of the second conductive clamping part 32, which is conducive to more stable clamping of the cathode conductive component 200. Moreover, the simultaneous contact of multiple first conductive springs 310 and multiple second conductive springs 320 with the cathode conductive component 200 can ensure sufficient contact area between the first conductive clamping part 31 and the second conductive clamping part 32 and the cathode conductive component 200. This can not only further ensure a good electrical connection between the cathode conductive component 200 and the conductive device 100, but also ensure that the cathode conductive component 200 can rotate stably within the clamping cavity 30 between the first conductive clamping part 31 and the second conductive clamping part 32, which can further improve the working reliability of the photovoltaic cell electroplating equipment.

[0051] As an embodiment of the present invention, the first conductive spring 310 includes a first deformable portion 311 connected to a wiring portion 12 and a first contact portion 312 connected to the first deformable portion 311; the second conductive spring 320 includes a second deformable portion 321 connected to another wiring portion 12 and a second contact portion 322 connected to the second deformable portion 321, and the first contact portion 312 and the second contact portion 322 are spaced apart to form a clamping cavity 30.

[0052] In this embodiment, both the first deformation portion 311 and the second deformation portion 321 can generate elastic deformation. The design of the first deformation portion 311 and the second deformation portion 321 can increase the elastic deformation capability of the first conductive clamping portion 31 and the second conductive clamping portion 32, respectively, so that the first contact portion 312 and the second contact portion 322 can clamp the cathode conductive component 200 more stably. Moreover, the first contact portion 312 and the second contact portion 322 can contact the cathode conductive component 200 simultaneously, which can ensure sufficient contact area between the first conductive clamping portion 31 and the second conductive clamping portion 32 and the cathode conductive component 200. This can not only further ensure a good electrical connection between the cathode conductive component 200 and the conductive device 100, but also ensure that the cathode conductive component 200 can rotate stably within the clamping cavity 30 between the first conductive clamping portion 31 and the second conductive clamping portion 32, which can further improve the working reliability of the photovoltaic cell electroplating equipment.

The first guide portion 313 and the second guide portion 323 form a guide opening 300 that communicates with the clamping cavity 30, and the width W1 of the guide opening 300 away from the clamping cavity 30 is greater than the width W2 of the guide opening 300 close to the clamping cavity 30.

The guide surfaces on the first guide portion 313 and the guide surfaces on the second guide portion 323 can be inclined surfaces, arc surfaces, or a combination of inclined surfaces and arc surfaces.

The cathode conductive element 200 can enter the clamping cavity 30 through the guide opening 300 formed between the first guide portion 313 and the second guide portion 323 and be clamped in the clamping cavity 30. Due to the arrangement of the first guide portion 313 and the second guide portion 323, they play a guiding role when the cathode conductive element 200 enters the clamping cavity 30, which facilitates the installation of the conductive device 100 and the cathode conductive element 200.
