A mainstream solar cell module consists of a front glass panel, a primary encapsulating film, a silicon crystalline cell string, a secondary encapsulating film, and a back glass panel, all connected in sequence. The crystalline silicon cell string requires a stitch welder to weld the interconnecting bars and bus bars together, completing the circuit. After the interconnecting bars and bus bars are welded together, manual visual inspection and touch verification of the bus bars and interconnecting bars are performed.

[0030] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0031] Example 1

[0032] This embodiment provides a photovoltaic module inspection device for frictionally treating the connection locations of busbars 82 and interconnecting bars 81 in photovoltaic modules 8. The friction at the connection between interconnecting bars 81 and busbars 82, where there is a risk of a cold solder joint, causes the end of interconnecting bar 81 to deform, thereby exposing the location of the potential cold solder joint. The battery string of photovoltaic module 8 is powered on and inspected by an electrical inspection machine. If busbars 82 and interconnecting bars 81 have a deformed structure that indicates a cold solder joint and cannot form a path for the battery string, the electrical inspection machine can detect the location where the busbars 82 and interconnecting bars 81 are poorly welded. If busbars 82 and interconnecting bars 81 are well welded and can form a path for the battery string, the electrical inspection machine detects that the photovoltaic module 8 is qualified.

[0033] The electrical testing machine is a conventional device for photovoltaic modules 8 and will not be described in detail here.

[0034] Figure 1 A schematic diagram of a photovoltaic module detection device provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the detection platform provided in an embodiment of the present application.

[0035] like Figure 1 、 Figure 2 As shown, this embodiment provides a photovoltaic module detection device, including a detection platform 1, a first driving module 2 arranged on both sides of the detection platform 1, a moving beam 3 driven by the first driving module 2 to move longitudinally, a second driving module 4 arranged on the moving beam 3, a sliding beam 5 driven by the second driving module 4 to move laterally, a plurality of bracket bodies 6 detachably connected to the sliding beam 5, and a friction member 7 arranged at the end of the bracket body 6; the distance of the bracket body 6 relative to the detection platform 1 can be adjusted.

[0036] In this embodiment, the longitudinal direction is set as the Y direction, the transverse direction is set as the X direction, and the vertical direction is set as the Z direction, that is, the direction of the bracket body 6 relative to the detection platform 1 is the Z direction. Among them, the detection platform 1 is in a horizontal direction, and the detection platform 1 is used to position the photovoltaic module 8. A carrier can be set on the detection platform 1. The carrier conforms to the structure of the photovoltaic module 8 and can effectively position the photovoltaic module 8. In order to simplify the structure of the detection platform 1, in this embodiment, the photovoltaic module 8 is directly positioned on the detection platform 1. Multiple groups of photovoltaic modules 8 can be set on the detection platform 1. This embodiment is described by taking two groups of photovoltaic modules 8 set on the detection platform 1 as an example. The two groups of photovoltaic modules 8 are symmetrically arranged on both sides of the detection platform 1.

[0037] Photovoltaic module 8 includes several cell strings, each of which is formed by interconnecting cells 81. Several interconnecting cells 81 are connected to busbars 82. The connections between busbars 82 and interconnecting cells 81 may contain cold welds. Friction member 7 rubs these connections, causing warping of interconnecting cells 81 where these cold welds are present. Specifically, bracket body 6 is driven to move laterally and longitudinally, allowing friction member 7 to sweep the connections between busbars 82 and interconnecting cells 81, applying frictional force to the connections between interconnecting cells 81 and busbars 82.

[0038] In this embodiment, the friction member 7 may be a fibrous structure, specifically a brush. The friction member 7 is detachably connected to the support body 6. As a consumable part, the friction member 7 can be replaced periodically. The friction member 7 and the support body 6 may be connected by screwing, snapping, or other means, which are not limited in this embodiment.

[0039] In this embodiment, the distance between the bracket body 6 and the detection platform 1 is adjustable, so that the friction part 7 corresponds to the position of the photovoltaic component 8 to be friction-treated on the detection platform 1. The friction treatment of the friction part 7 can cause the interconnection bar 81 and the bus bar 82 on the photovoltaic component 8 to be warped and deformed at the position where the welding is poor, and accurately identify the position of the poor welding, providing a basis for further accurate identification of hidden dangers in the subsequent detection process; the bracket body 6 is installed on the sliding beam 5, and the sliding beam 5 is installed on the moving beam 3. The bracket body 6 can realize multi-directional movement operation, and can realize the detection of large quantities of photovoltaic components 8, thereby improving the accuracy and efficiency of detecting the poor welding positions of the interconnection bar 81 and the bus bar 82.
