[0037] See also Figure 1 and Figure 2An embodiment of the present application provides a photovoltaic welding device, including a housing 1, a mounting assembly 2 and a collecting assembly 3. The housing 1 is used to accommodate the welding assembly 5, so that the photovoltaic sheet can be welded in the housing 1 through the welding assembly 5. The collecting assembly 3 is used to collect photovoltaic sheets with missing corners, broken pieces, dirt and other problems for subsequent centralized processing. The mounting assembly 2 is used to install the collecting assembly 3 on the housing 1, so that the collecting assembly 3 can collect the photovoltaic sheets in the housing 1.

[0038] In the specific configuration, the mounting assembly 2 is arranged inside the housing 1, and the housing 1 is provided with a through hole 13 penetrating into the housing 1 along a first direction, and the collecting assembly 3 is slidably arranged on the mounting assembly 2 along the first direction, and the collecting assembly 3 is penetrated in the through hole 13, so that the collecting assembly 3 can push and pull relative to the through hole 13. When the staff pulls the collecting assembly 3 out of the housing 1, the unqualified photovoltaic sheets in the collecting assembly 3 can be taken out and processed, and when the staff pushes the collecting assembly 3 into the housing 1, the collecting assembly 3 can continue to collect the unqualified photovoltaic sheets.

[0039] Specifically, the housing 1 is provided with a detection component and a welding component 5. Before the welding component 5 welds the photovoltaic sheet, the detection component first performs an appearance inspection on the photovoltaic sheet to confirm whether the edges and corners of the photovoltaic sheet are free of problems such as missing corners, broken pieces, dirt, etc. If it is determined that the photovoltaic sheet has problems such as missing corners, broken pieces, dirt, etc., the photovoltaic sheet is moved to the collection box 32 for centralized collection. If it is determined that the photovoltaic sheet does not have problems such as missing corners, broken pieces, dirt, etc., the photovoltaic sheet is moved to the welding component 5 for welding. When the number of photovoltaic sheets in the collection box 32 reaches the set number, the staff can pull the collection component 3 out of the housing 1, and then take out the unqualified photovoltaic sheets in the collection component 3 for subsequent processing. After the staff takes out all the unqualified photovoltaic sheets in the collection component 3, the collection component 3 can be pushed back into the housing 1 so that the collection component 3 continues to collect the unqualified photovoltaic sheets.

[0040] In summary, the photovoltaic welding device of the present application collects unqualified photovoltaic sheets through the collecting component 3 that passes through the opening 13 and can be pulled and moved along the first direction, so that the staff can take out the unqualified photovoltaic sheets in the collecting component 3 by pulling the collecting component 3 out of the casing 1. The operation is convenient and quick, and there is no need to shut down the equipment during taking, thereby ensuring production efficiency, production capacity and production working hours.

[0041] See also Figure 1 and Figure 3In one embodiment, the collection assembly 3 includes a collection rack 31 and a collection box 32. The collection box 32 is detachably arranged on the collection rack 31, so that the collection box 32 can be removed from the collection rack 31, so that the staff can take and process the photovoltaic sheets in the collection box 32. The collection rack 31 is slidably arranged on the mounting assembly 2, so that the collection rack 31 can drive the collection box 32 to move along the first direction on the mounting assembly 2, and the collection box 32 passes through the through opening 13 during the movement, so that the staff can take and process the photovoltaic sheets in the collection box 32.

[0042] Specifically, the collection rack 31 is provided with a placement slot 33, and the collection box 32 is accommodated in the placement slot 33 to achieve a detachable connection between the collection box 32 and the collection rack 31. The collection box 32 is provided with a collection slot, and unqualified photovoltaic cells can be placed in the collection slot. After the staff pulls the collection assembly 3 out of the housing 1, the collection box 32 together with the photovoltaic cells inside can be removed from the collection rack 31, and then another empty collection box 32 can be placed on the collection rack 31. Compared with the method of taking out the photovoltaic cells in the collection box 32 on the collection rack 31, the method of directly replacing the empty collection box 32 is faster and more efficient.

[0043] More specifically, the placement groove 33 is opened on the first surface of the collection rack 31 and extends a distance into the interior of the collection rack 31. The collection groove is opened on the second surface of the collection box 32 and extends a distance into the interior of the collection rack 31. The first surface and the second surface are both parallel to the first direction to ensure that after the collection box 32 is placed in the placement groove 33, the collection groove can be exposed so that the photovoltaic panel can be placed.

[0044] See also Figure 3 and Figure 4 In one embodiment, the collection assembly 3 further includes a connecting member 34, which is fixedly connected to one end of the collection rack 31 close to the outside of the housing 1, and the area of ​​the cross section of the connecting member 34 perpendicular to the first direction is consistent with the opening area of ​​the through-port 13, so that the connecting member 34 can block the through-port 13, improve the aesthetics and prevent dust from entering the interior of the housing 1 through the gap between the collection rack 31 and the through-port 13. Specifically, the connecting member 34 is a connecting plate.

[0045] In addition, the collecting assembly 3 further comprises a handle 35 , which is disposed on a side of the connecting member 34 away from the collecting frame 31 along the first direction, so that the staff can perform a pulling operation on the collecting assembly 3 .

[0047] See also Figure 2In one embodiment, a dicing assembly 4 and a welding assembly 5 are provided in the housing 1, and the dicing assembly 4 and the welding assembly 5 are spaced apart along the second direction. By simultaneously providing the dicing assembly 4 and the welding assembly 5 in the housing 1, the photovoltaic welding device of the present application can not only weld the photovoltaic sheet through the welding assembly 5, but also cut the photovoltaic sheet through the dicing assembly 4, so as to cut the whole large photovoltaic sheet into individual small photovoltaic sheets for subsequent welding operations.

[0048] Along the second direction, the mounting assembly 2 is arranged between the dicing assembly 4 and the welding assembly 5, so that after the dicing assembly 4 cuts the whole large photovoltaic sheet into individual small photovoltaic sheets, the photovoltaic sheets detected to have problems such as missing corners, broken pieces, dirt, etc. can be directly moved to the collecting assembly 3 for centralized collection, and the photovoltaic sheets detected to have no problems such as missing corners, broken pieces, dirt, etc. can be directly moved to the welding assembly 5 for welding operation. The second direction is perpendicular to the first direction, so that the pulling direction of the collecting assembly 3 is perpendicular to the arrangement direction of the dicing assembly 4, the mounting assembly 2 and the welding assembly 5, so as to realize the reasonable arrangement of the dicing assembly 4, the collecting assembly 3, the mounting assembly 2 and the welding assembly 5.

[0049] See also Figure 2 In one embodiment, the mounting assembly 2 includes a mounting frame 21 and a slide rail 22, the slide rail 22 is disposed on the mounting frame 21, the slide rail 22 has a slider that can slide along a first direction, and the slider is connected to the collection assembly 3.

[0050] Specifically, at least two slide rails 22 are provided, and at least two slide rails 22 are evenly arranged on the mounting frame 21 along the second direction, each slide rail 22 has at least one slider, and each slider is connected to the collecting assembly 3. By increasing the number of slide rails 22, the smoothness and stability of the collecting assembly 3 when sliding on the mounting frame 21 are ensured. The mounting frame 21 adopts a profile to ensure the supporting effect of the collecting assembly 3. More specifically, the profile adopted by the mounting frame 21 can be a lightweight, high-strength, low-cost aluminum alloy, or can be a metal material such as iron and stainless steel.

[0051] See also Figure 1 and Figure 2 In one embodiment, the housing 1 includes a main housing 11 and a safety door 12, and the safety door 12 is movably connected to the main housing 11. The staff can check or repair the equipment inside the housing 1 by opening the safety door 12. The through hole 13 is set on the safety door 12, and the collection component 3 can pass through the installation door when being pulled out, so that the staff can face the installation door to pull out the collection component 3.

[0052] Specifically, the safety door 12 includes a first door body 121 and a second door body 122, both of which are movably connected to the main housing 11, a first notch is provided on a side of the first door body 121 close to the second door body 122, and a second notch is provided on a side of the second door body 122 close to the first door body 121, and the first notch and the second notch cooperate to form a through opening 13. Compared with one door, two doors can reduce the space occupied by the photovoltaic welding device while ensuring the observation range.

[0053] More specifically, an observation window 14 is further provided on the first door body 121 and / or the second door body 122 , so that the staff can directly check the status of the equipment inside the casing 1 through the observation window 14 without opening the safety door 12 .

[0054] In one embodiment, a sensor for sensing the position of the collecting assembly 3 and a transplanting component for clamping the photovoltaic sheet may be provided inside the housing 1, and the sensor is electrically connected to the transplanting component. When the staff pulls the collecting assembly 3 out of the housing 1, the sensor can timely sense the position change of the collecting assembly 3 and control the transplanting component to stop working, so as to ensure that the transplanting component will not place new photovoltaic sheets with missing corners, broken pieces, dirt, etc. After the staff pushes the collecting assembly 3 back into the housing 1, the sensor gives a signal to the transplanting component to make it continue to work.
