Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic module assembly equipment, and particularly relates to a wire clamp mechanism for electrical property testing of perovskite photovoltaic modules.

Background Art

[0002] At present, there is a frameless perovskite photovoltaic module that needs to be subjected to various electrical property tests after being manufactured, including insulation withstand voltage test. The withstand voltage test of the perovskite photovoltaic module is different from that of the conventional framed photovoltaic module. Its electrical conduction points are not located on the upper surface or the lower surface of the photovoltaic module, nor are they point-distributed, but on the outer peripheral side surface. Therefore, it is impossible to use the conductive probes in the prior art to conduct electrical connection.

[0003] Therefore, it is necessary to provide a new wire clamp mechanism for electrical property testing of perovskite photovoltaic modules to solve the above technical problems.

Content of the Utility Model

[0004] The main purpose of the utility model is to provide a wire clamp mechanism for electrical property testing of perovskite photovoltaic modules, which can stably and reliably achieve the electrical connection of perovskite photovoltaic modules and provide a prerequisite for realizing electrical property testing.

[0005] The utility model realizes the above purpose through the following technical scheme: A wire clamp mechanism for electrical property testing of perovskite photovoltaic modules, which includes a support cross beam, a slide rail fixed on the support cross beam, a support platform that is arranged on the slide rail with adjustable position and is used to support the perovskite photovoltaic module, a first wire clamp assembly and a second wire clamp assembly that are arranged on the slide rail with adjustable position and are located on opposite sides of the support platform; the first wire clamp assembly and the second wire clamp assembly have the same structure and both include a slider slidably arranged on the slide rail, a support plate fixed on the slider, a clamping plate perpendicularly arranged on the support plate with respect to the support cross beam, a conductive foam filled in the clamping plate, and a locking member for locking the slider on the slide rail; the clamping plate or the conductive foam is electrically connected to the test equipment.

[0006] Further, a hollow cavity is formed in the clamping plate, a long strip-shaped slot communicating with the hollow cavity is opened on one side surface of the clamping plate facing the perovskite photovoltaic module, and the conductive foam is filled in the hollow cavity and is exposed corresponding to the long strip-shaped slot area.

[0007] Further, both ends of the hollow cavity are through and open structures.

[0008] Further, the clamping plate is made of a conductive material, and a lead perforation for facilitating electrical connection to the test equipment is arranged at its end.

[0009] Compared with the prior art, the beneficial effects of the wire clamp mechanism for electrical property testing of a perovskite photovoltaic module of the present utility model are as follows: Two clamping plates are arranged on opposite sides of the support platform for supporting the product. The clamping plates are designed as hollow cavity structures, and conductive foam is filled in the hollow cavities. A long strip-shaped slot is opened on the surface of the clamping plate facing the product to be tested. The product is clamped and fixed by the clamping plates in a clamping manner. At the same time, the conductive foam exposed in the long strip-shaped slot area is in C-shaped wrapped contact with the side surface of the perovskite photovoltaic module, thereby realizing electrical conduction and providing a reliable guarantee for electrical property testing; The positions of the two clamping plates are flexibly adjustable and can be applied to clamping components of various different specifications and sizes, with high versatility.

Detailed Embodiment

[0016] Embodiment 1:

[0017] Please refer to Figures 1 - 3 , this embodiment is a wire clamp mechanism 100 for electrical property testing of a perovskite photovoltaic module, which includes a support cross beam 1, a slide rail 2 fixed on the support cross beam 1, a support platform 3 which is arranged on the slide rail 2 and can be adjusted in position and is used to support the perovskite photovoltaic module, and a first wire clamp assembly 4 and a second wire clamp assembly 5 which are arranged on the slide rail 2 and can be adjusted in position and are located on opposite sides of the support platform 3.

[0018] The first wire clamp assembly 4 and the second wire clamp assembly 5 have the same structure and both include a slider 41 slidably arranged on the slide rail 2, a support plate 42 fixed on the slider 41, a clamping plate 43 perpendicular to the support cross beam 1 arranged on the support plate 42, a conductive foam 44 filled in the clamping plate 43, and a locking member 45 for locking the slider 41 on the slide rail 2; the clamping plate 43 or the conductive foam 44 is electrically connected to the testing device.

[0019] A hollow cavity 431 is formed in the clamping plate 43, and a long strip-shaped slot 432 communicating with the hollow cavity 431 is formed on one side surface of the clamping plate 43 facing the perovskite photovoltaic module. The conductive foam 44 is filled in the hollow cavity 431 and is exposed corresponding to the area of the long strip-shaped slot 432. The long strip-shaped slot 432 is used for exposing the conductive foam 44 on the one hand, and can limit the side edge of the photovoltaic module on the other hand. During testing, the edge of the photovoltaic module extends into the long strip-shaped slot 432, so as to ensure that the conductive foam 44 can effectively and reliably contact the side surface of the photovoltaic module, thereby realizing stable and reliable electrical connection and ensuring the reliability of the electrical testing process.

[0020] Both ends of the hollow cavity 431 are of a through-open structure to facilitate the replacement of the conductive foam 44.

[0021] The clamping plate 43 is made of a conductive material, and a lead perforation 433 for facilitating electrical connection to the testing device is arranged at its end.

[0022] During testing, the first wire clamp assembly 4 can be fixed and kept stationary after adjusting the position, while the second wire clamp assembly 5 can be adjusted in position according to different product sizes. At the same time, by fixing or loosening the second wire clamp assembly 5, the clamping and loosening operations of the product can also be realized, which is convenient for taking, placing and clamping the product.

[0023] When the wire clamp mechanism 100 for electrical testing of a perovskite photovoltaic module in this embodiment is in use, first, according to the size of the component to be tested, the positions of the first wire clamp assembly 4 and the second wire clamp assembly 5 are adjusted, and then the first wire clamp assembly 4 is fixedly locked; the component to be tested is placed on the support platform 3, and the second wire clamp assembly 5 is pushed along the slide rail 2 to approach the first wire clamp assembly 4, and the component to be tested is clamped from the left and right sides by the first wire clamp assembly 4 and the second wire clamp assembly 5, and electrical connection is realized by the conductive foam 44 in the wire clamp assembly contacting the side edge of the perovskite photovoltaic module.

[0024] For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
