[0020] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0021] Specific embodiment 1: Please refer to Figure 1-4 A robot automatic welding box machine is used for welding the junction box of photovoltaic modules, comprising: a frame 1, an inlet and outlet assembly line 2, a correction mechanism 3, a limit mechanism 4, a displacement mechanism 5, a four-axis robot 6, a welding gun 7, a visual positioning mechanism 8, a mounting plate 9 and a support plate 10, wherein the inlet and outlet assembly line 2, the correction mechanism 3, the limit mechanism 4, and the displacement mechanism 5 are all installed on the frame 1, wherein the inlet and outlet assembly line 2 is arranged on the inner side of the frame 1 for conveying the photovoltaic modules to the inner side of the welding box machine, and the correction mechanism 3 is arranged on both sides of the inlet and outlet assembly line 2 for pushing the photovoltaic modules entering the welding box machine on four sides to play a central positioning role The limiting mechanism 4 is arranged at the lower side of the inlet and outlet assembly line 2 to block the input photovoltaic components to assist the correction mechanism 3 in positioning. The displacement mechanism 5 is arranged at the upper side of the inlet and outlet assembly line 2. The four-axis robot 6 is arranged on the displacement mechanism 5. Driven by the displacement mechanism 5, the four-axis robot 6 can realize lateral movement on the upper side of the inlet and outlet assembly line 2, and the lateral movement direction is perpendicular to the conveying direction of the inlet and outlet assembly line 2; the welding gun 7 is arranged at the execution end of the four-axis robot 6 through the mounting plate 9, and the visual positioning mechanism 8 is arranged at the execution end of the four-axis robot 6 through the support plate 10 and the position corresponds to the welding gun 7, which is used to assist the welding gun 7 in performing precise spot welding.

[0022] Specifically, the displacement mechanism 5 includes a crossbeam 51 and two groups of linear modules 52. The two groups of linear modules 52 are arranged on the frame 1, and their laying direction is perpendicular to the conveying direction of the inlet and outlet assembly line 2; the crossbeam 51 is erected between the two groups of linear modules 52, and under the drive of the linear modules 52, the crossbeam 51 can move horizontally left and right on the upper side of the inlet and outlet assembly line 2; further, the crossbeam 51 is a hollow columnar structure.

[0023] The mounting end of the four-axis robot 6 is fixedly connected to the crossbeam 51. When in use, the displacement mechanism 5 can drive the four-axis robot 6 to perform a relatively large lateral movement on the upper side of the in-and-out material assembly line 2. In this embodiment, with the assistance of the displacement mechanism 5, the longitudinal projection area of ​​all strokes of the execution end of the four-axis robot 6 on the upper side of the in-and-out material assembly line 2 should not be less than the longitudinal projection area of ​​the space inside the rack 1, so that the execution end of the four-axis robot 6 can achieve full coverage of all points on the photovoltaic components entering the inner side of the rack 1;

[0024] The mounting plate 9 is composed of a connecting portion 91 and a folding portion 92. The connecting portion 91 is fixedly connected to the execution end of the four-axis robot 6, and the supporting plate 10 is fixedly connected to the connecting portion 91. The folding portion 92 can provide more supporting points for the welding gun 7 to make the welding gun 7 more stable.

[0025] In this embodiment, the support plate 10 is a U-shaped plate structure, a through hole is longitudinally opened on the support plate 10, the visual positioning mechanism 8 is arranged on the lower side of the through hole and the visual positioning mechanism 8 is within the range of the longitudinal projection of the support plate 10, and the outer edge of the support plate 10 can provide more protection for the visual positioning mechanism 8 to avoid the visual positioning mechanism 8 being accidentally injured when the four-axis robot 6 is in action; it should be noted that the visual positioning mechanism 8 is used to determine the welding point to assist the action of the execution end of the four-axis robot 6.

[0026] In this embodiment, the welding wire box machine also includes a control system, which is circuit-connected to the feed and discharge assembly line 2, the correction mechanism 3, the limit mechanism 4, the displacement mechanism 5, the four-axis robot 6, the welding gun 7, and the visual positioning mechanism 8 to improve the degree of automation of the welding wire box machine.

[0027] The working principle of the present welding junction box machine is as follows: the photovoltaic module is transported into the equipment through the feed-in and feed-out assembly line 2, and the correcting mechanism 3 and the limiting mechanism 4 center the photovoltaic module. After the positioning is completed, the displacement mechanism 5 and the four-axis robot 6 drive the visual positioning mechanism 8 and the welding gun 7 to move to the top of the photovoltaic module junction box. According to the parameters set in advance by the control system, with the assistance of the visual positioning mechanism 8, the welding gun 7 sequentially welds the bus bar and the copper base plate on the photovoltaic module junction box on the photovoltaic module according to the set welding path. After the welding is completed, the correcting mechanism 3 and the limiting mechanism 4 release the photovoltaic module, and the photovoltaic module is transported out of the equipment through the feed-in and feed-out assembly line 2 to complete the welding.

[0028] The overall layout of the welding wire box machine is compact. A displacement mechanism 5 is arranged on the upper side of the feeding and discharging assembly line 2, and a four-axis robot 6 is arranged on the displacement mechanism 5. Driven by the displacement mechanism 5, the execution end of the four-axis robot 6 can fully cover all points on the photovoltaic components entering the inner side of the frame 1. The welding gun 7 and the visual positioning mechanism 8 are both installed on the execution end of the four-axis robot 6. Compared with the existing junction box welding machine, the structure of the welding wire box machine is simpler, and the later maintenance is more time-saving and labor-saving. At the same time, the welding wire box machine also has the characteristics of multiple welding positions and points, which can meet the welding work of photovoltaic components of different models and has a wide range of applications.
