[0036] Figure 1 This is a structural diagram of a first embodiment of a junction box welding device of the present invention; Figure 2 FIG. 1 is a structural block diagram of a first embodiment of a junction box welding device of the present invention. In the first embodiment of the present invention, the junction box welding device 100 includes a welding machine 110 , a recognition camera 120 , a position recognition circuit 130 , and a shift control circuit 140 .

[0037] The identification camera 120 is set on the welding machine 110 and faces the junction box 200. The junction box 200 includes an inspection position A1 and a welding position A2. The inspection position A1 is set at the diode 210 of the junction box 200, and the welding position A2 is set at the bus bar 220 of the junction box 200. There is a preset distance between the inspection position A1 and the welding position A2, and the diode 210 of the junction box 200 is electrically connected to the bus bar 220 of the junction box 200.

[0038] The position recognition circuit 130 is electrically connected to the recognition camera 120 . The position recognition circuit 130 is configured to recognize the position of the diode 210 according to the recognition camera 120 to obtain the verification bit A1 , and recognize the position of the bus bar 220 according to the recognition camera 120 .

[0039] The shift control circuit 140 is electrically connected to the welding machine 110 and the recognition camera 120 respectively. The shift control circuit 140 is configured to obtain the welding position A2 according to the preset spacing, the inspection position A1 and the position of the bus bar 220, and control the welding machine 110 to move to the welding position A2 to weld the bus bar 220.

[0040] In an embodiment of the present invention, before the welding machine 110 welds the bus bar 220 of the junction box 200, the position recognition circuit 130 can obtain a visual image of the junction box 200 to be welded by the recognition camera 120, and recognize the position of the diode 210 of the junction box 200 based on the visual image to determine the position of the inspection position A1 corresponding to the diode 210, and recognize the position of the bus bar 220 of the junction box 200 based on the visual image.

[0041] A bus bar 220 is provided on both sides of the diode 210 of the junction box 200 to be welded. The bus bar 220 and the diode 210 have a fixed preset distance, and the bus bar 220 and the diode 210 are electrically connected. The current can flow unidirectionally through the bus bar 220 and the diode 210 in the junction box 200.

[0042] After the position recognition circuit 130 identifies and determines the inspection position A1, the shift control circuit 140 can calculate the exact position of the welding position A2 covered by the busbar 220 based on the position of the inspection position A1, the position of the busbar 220, and the preset distance between the busbar 220 and the diode 210. After obtaining the exact position of the welding position A2, the shift control circuit 140 can control the welding machine 110 to move to the welding position A2 of the busbar 220 by recognizing the image transmitted by the camera 120 to weld the busbar 220.

[0043] The position recognition circuit 130 and the shift control circuit 140 in the embodiment of the present invention can adopt existing solutions. For example, the position recognition circuit 130 can adopt an RFID recognition circuit, an optical camera recognition circuit, etc., and the shift control circuit 140 can adopt a PID controller, a position proportional control circuit, etc., to realize the recognition of visual images and the position control of the welding machine 110.

[0044] The junction box welding device 100 of the embodiment of the present invention can accurately control the welding machine 110 to move to the welding position A2 to weld the busbar 220, thereby improving the welding accuracy of the junction box 200 and reducing the rework rate and production cost of the junction box 200.

[0045] The position recognition circuit 130 of the junction box welding device 100 of the embodiment of the present invention can identify the position of the diode 210 of the junction box 200 through the recognition camera 120 to obtain the inspection position A1, and can also identify the position of the bus bar 220. Since there is a preset distance between the welding position A2 located on the bus bar 220 and the inspection position A1 located on the diode 210, the shift control circuit 140 can obtain the accurate position of the welding position A2 through the position of the bus bar 220, the position of the inspection position A1 and the preset distance, and control the welding machine 110 to weld the welding position A2 of the bus bar 220, thereby avoiding cold welding or over-welding of the bus bar 220 due to inaccurate positioning, thereby ensuring the welding quality of the bus bar 220.

[0046] In some embodiments, the junction box welding device 100 further includes a correction component 150, which is electrically connected to the shift control circuit 140. The welding machine 110 is detachably mounted on the correction component 150. The correction component 150 can drive the welding machine 110 to approach the junction box 200, or move away from the junction box 200, or reciprocate in a direction parallel to the junction box 200.

[0047] In this embodiment, after the shift control circuit 140 acquires a visual image of the junction box 200 through the recognition camera 120 and determines the welding position A2 of the busbar 220, it controls the return assembly 150 to drive the welding machine 110 to move to the welding position A2 of the busbar 220 and weld the busbar 220. After welding one busbar 220 of the junction box 200 is completed, the return assembly 150 is further controlled to drive the welding machine 110 to move to the welding position A2 of another busbar 220 to weld it. After welding is completed, the return assembly 150 is controlled to drive the welding machine 110 away from the junction box 200 where the welding is completed, completing the welding of the busbars 220 of the junction box 200.

[0048] Furthermore, the welding machine 110 includes a welding rod 111 and a welding head 112 , and the lens of the recognition camera 120 is oriented toward the welding head 112 .

The recognition camera 120 located on the welding rod body 111 can judge the position of the welding head 112 relative to the junction box 200 based on the recognized visual image, so that the shift control circuit 140 can accurately control the welding head 112 to move to the welding position A2 based on the visual image.

[0051] In this embodiment, since the plane formed by the first direction X and the second direction Y is parallel to the junction box 200, the first telescopic end 1511 of the first driving member 151 and the second telescopic end 1521 of the second driving member 152 can control the welding machine 110 to reciprocate along the first direction X and the second direction Y respectively, so as to enable the welding machine 110 to move back and forth in a direction parallel to the junction box 200 to adjust the position of the welding head 112 of the welding machine 110 relative to the junction box 200.

[0052] Furthermore, the correction component 150 also includes a third driving member 153, and the third driving member 153 includes a third telescopic end 1531. The third driving member 153 can drive the third telescopic end 1531 to drive the welding machine 110 to reciprocate along the third direction Z, and the third direction Z is perpendicular to the plane formed by the first direction X and the second direction Y.

[0053] In this embodiment, after the welding head 112 of the welding machine 110 is adjusted to a position opposite to the welding position A2 by the first driving member 151 and the second driving member 152, the welding head 112 is controlled by the third driving member 153 to approach the welding position A2 of the busbar 220 along the third direction Z and weld the busbar 220. After the welding is completed, the welding head 112 is controlled to move away from the busbar 220 along the third direction Z to complete the welding of the busbar 220.

[0054] The first driving member 151 , the second driving member 152 and the third driving member 153 may be driving devices such as cylinders, hydraulic cylinders, or screw rods that can drive the welding machine 110 to telescopic movement.

[0055] Specifically, the welding rod body 111 is detachably connected to the first telescopic end 1511 , the second telescopic end 1521 and the third telescopic end 1531 .

[0056] In this embodiment, by detachably connecting the welding rod 111 to the first telescopic end 1511, the second telescopic end 1521, and the third telescopic end 1531, the welding rod 111 can be conveniently disassembled, replaced, and maintained when the welding machine 110 needs to be replaced or maintained, thereby reducing maintenance costs and improving maintenance efficiency. Furthermore, the connection angles between the first telescopic end 1511, the second telescopic end 1521, and the third telescopic end 1531 and the welding rod 111 can be adjusted at any time, facilitating adjustment of the movement direction of the welding rod 111.
