Technical Field

[0001] The utility model relates to the technical field of photovoltaic component manufacturing, in particular to a photovoltaic component junction box welding detection module. Background Art

[0002] In the field of photovoltaic power generation technology, the current on the photovoltaic panel flows to the junction box through the busbar, and the power is output through the wires of the junction box. Therefore, the welding effect between the junction box and the busbar (i.e., the electrical connection effect) is closely related to the power transmission capacity of the photovoltaic module panel. After the junction box is welded, a camera is usually used to take pictures of the weld scars and appearance of the welding points to judge the actual welding effect. However, this appearance inspection has certain limitations, and there is no way to detect whether the welding effect is firm. Summary of the invention

[0003] The utility model aims to provide a photovoltaic module junction box welding detection module, which can realize welding firmness detection and make the detection result more reliable.

[0009] Furthermore, the pusher claw assembly also includes a pusher claw seat for carrying the two pusher claws, and the pusher claw seat is arranged on the mounting frame or the pressing platform; the mounting frame is connected to a first driving member for driving it to rise and fall.

[0010] Furthermore, the pusher claw assembly also includes a pusher claw seat for carrying the two pusher claws, and the pusher claw seat is located between the mounting frame and the pressing platform; the pusher claw seat and the mounting frame are driven by the two first driving members to move downward respectively.

[0011] Furthermore, the claw seat is connected to a second driving member for driving the claw seat to move in the width direction of the busbar.

[0012] Furthermore, the pusher claw can be movably arranged on the pusher claw seat up and down, and a second elastic member is arranged between the pusher claw and the pusher claw seat.

[0013] Furthermore, the second elastic member is a spring sleeved on the upper part of the pusher claw.

[0014] Furthermore, the bottom surface of the pressing platform is connected to two pressing blocks, and the two pressing blocks are respectively arranged on both sides of the avoidance hole.

[0022] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0023] like Figures 1 to 3 As shown, a photovoltaic module junction box welding detection module includes a mounting frame 1, a pressing platform 2 for pressing the junction box 100, and a claw assembly 3.

[0024] Specifically, the pressing platform 2 is connected to the bottom of the mounting frame 1 through a group of first elastic members 7; the pressing platform 2 is provided with an avoidance hole 21. The photovoltaic module junction box welding detection module also includes a group of vertical guide columns 6; in the mounting frame 1 and the pressing platform 2, one of them is fixedly connected to the guide column 6, and the other is movably connected to the guide column 6 up and down. Preferably, the first elastic member 7 is a spring sleeved on the guide column 6. In this embodiment, by providing a group of first elastic members 7, it is possible to prevent the junction box 100 from being damaged by excessive pressure, and at the same time, the junction box 100 can be kept stationary during the detection process, thereby preventing the junction box 100 from being offset and affecting the detection result.

[0025] Furthermore, two pressing blocks 22 are connected to the bottom surface of the pressing platform 2, and the two pressing blocks 22 are respectively arranged on both sides of the avoidance hole 21. In this embodiment, since two pressing blocks 22 are added to the pressing platform 2, a thinner pressing platform 2 can be used, so that the weight of the pressing platform 2 and the two pressing blocks 22 is lighter, thereby reducing the burden of each first elastic member 7 and extending the service life.

[0026] like Figure 2 and 3 As shown, the pusher claw assembly 3 includes two pusher claws 31 located in the avoidance hole 21 and a pusher claw seat 32 for carrying the two pusher claws 31. The pusher claw 31 is movably arranged on the pusher claw seat 32, and a second elastic member 33 is arranged between the pusher claw 31 and the pusher claw seat 32. The second elastic member 33 is preferably a spring sleeved on the upper part of the pusher claw 31. The pusher claw seat 32 is connected to a second driving member 5 that drives it to move in the width direction of the busbar. The second driving member 5 is preferably a cylinder. In this embodiment, by adding the second elastic member 33, the pusher claw 31 can have a certain elastic range of movement in the vertical direction, thereby ensuring that the lower end of the pusher claw 31 can directly move downward to one side of the busbar.

[0027] As an embodiment of the present invention, the claw seat 32 and the second driving member 5 are both arranged on the mounting frame 1 or the pressing platform 2; the mounting frame 1 is connected to a first driving member 4 for driving the mounting frame 1 to rise and fall. The first driving member 4 is preferably a cylinder.

[0028] A photovoltaic module junction box welding detection module of the present embodiment, when in use, driven by the first driving member 4, the mounting frame 1 and the claw assembly 3 move downward together, and the pressing platform 2 contacts the junction box 100; the mounting frame 1 and the claw assembly 3 continue to move downward until the lower ends of the two claws 31 move to one side of the bus bar; driven by the second driving member 5, the claw assembly 3 moves along the width direction of the bus bar, and the two claws 31 apply a lateral thrust to the bus bar; if the welding between the junction box 100 and the bus bar is good, the bus bar will not be offset; if the welding between the junction box 100 and the bus bar is poor, the bus bar will be offset relative to the original position.

[0029] As another embodiment of the present invention, the claw seat 32 is located between the mounting frame 1 and the pressing platform 2; the claw seat 32 and the mounting frame 1 are driven by two first driving members 4 to move downwards respectively. The first driving member 4 is preferably a cylinder.

[0030] A photovoltaic module junction box welding detection module of this embodiment, when in use, under the drive of the first first driving member 4, the mounting frame 1 moves downward so that the pressing platform 2 is pressed on the junction box 100; under the drive of the second first driving member 4, the claw assembly 3 moves downward and the two claws 31 move to one side of the bus bar. Under the drive of the second driving member 5, the claw assembly 3 moves along the width direction of the bus bar so that the two claws 31 apply a lateral thrust to the bus bar; if the junction box 100 and the bus bar are well welded, the bus bar will not be offset; if the junction box 100 and the bus bar are poorly welded, the bus bar will be offset relative to the original position.

[0031] The photovoltaic module junction box welding detection module also includes a camera assembly for photographing the busbar, and the camera assembly includes an industrial camera and a light source. When in use, the camera assembly photographs the busbar before and after the force is applied to identify whether the position of the busbar is offset, thereby judging whether the welding between the junction box 100 and the busbar is firm, ensuring the production yield of the photovoltaic module, and avoiding hidden damage to the photovoltaic module due to poor contact of the welding position after entering the back-end process.

[0032] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
