[0028] The utility model provides a tensile test piece welding device, which includes: a battery fixing mechanism, a welding ribbon fixing mechanism, and a welding mechanism. The battery fixing mechanism is used to fix the solar cell to be welded to the battery station, the welding ribbon fixing mechanism is used to fix the welding ribbon to the welding ribbon station, and the welding mechanism includes a welding piece and a welding drive connected to the welding piece, and the welding drive is used to drive the welding piece to move along the welding ribbon station.

[0029] This tensile test piece welding device includes a battery fixing mechanism, a welding ribbon fixing mechanism, and a welding mechanism. The welding mechanism includes a welding component and a welding driver for driving the welding component. In actual use, the battery fixing mechanism fixes the solar cell to the battery station, the welding ribbon fixing mechanism fixes the welding ribbon to the welding ribbon station, and the welding driver drives the welding component to move along the welding ribbon station, welding the entire welding ribbon to the solar cell. After welding is completed, the relative movement between the battery station and the welding ribbon station allows for convenient and rapid direct tensile testing.

Since the welding process does not require manual operation by the operator, the impact on the operator can be minimized.

[0030] Figure 1 This is a schematic diagram of the cross-sectional structure of a tensile test piece welding device. Figure 1 As shown, in this embodiment, the tensile test piece welding device includes a cell fixing mechanism, a ribbon fixing mechanism, and a welding mechanism. The cell fixing mechanism is used to fix the solar cell to be welded to the cell station 101, the ribbon fixing mechanism is used to fix the ribbon to the ribbon station 201, and the welding mechanism includes a welding member 310 and a welding driver 320 connected to the welding member 310. The welding driver 320 is used to drive the welding member 310 to move along the ribbon station 201.

[0031] Cell station 101 refers to the station where the solar cells to be welded are located, while ribbon station 201 is the station where the ribbons to be welded are located. It is understood that the ribbons located at ribbon station 201 should be capable of being welded to the solar cells located at cell station 101. Furthermore, the ribbons located at ribbon station 201 can directly or indirectly contact the solar cells located at cell station 101 to ensure proper welding. During actual welding, flux may be placed between the ribbons and the solar cells.

[0032] Reference Figure 1 As shown, in some examples of this embodiment, the ribbon station 201 is arranged above the battery station 101.

[0033] Reference Figure 1As shown, in some examples of this embodiment, the soldering ribbon fixing mechanism includes two spaced-apart soldering ribbon clamps 210, each positioned on either side of the soldering ribbon station 201. It will be appreciated that, in actual use, the two soldering ribbon clamps 210 on either side of the cell station 101 can respectively clamp the ends of the soldering ribbon and secure it to the soldering ribbon station 201 by clamping. By employing two spaced-apart soldering ribbon clamps 210, the position and shape of the soldering ribbon can be maintained stable, thereby ensuring a high-quality weld between the soldering ribbon and the solar cell. Furthermore, the two spaced-apart soldering ribbon clamps 210 can free up space above the soldering ribbon station 201, facilitating welding of the soldering parts 310.

[0034] Figure 2 for Figure 1 The structure diagram of the welding ribbon clamp 210 is shown. Figure 1 and Figure 2 As shown, in some examples of this embodiment, the ribbon clamp 210 is provided with an elongated ribbon gap 2101. The ribbon gaps 2101 in the two ribbon clamps 210 are used in conjunction with each other to secure the ribbon to the ribbon station 201. It will be appreciated that in actual use, the ribbon can be inserted into the ribbon gap 2101 to secure the ribbon. The provision of the ribbon gap 2101 allows multiple parallel ribbons to be simultaneously clamped and stabilized using only two ribbon clamps 210, thereby improving work efficiency.

[0035] Combine Figure 1 and Figure 2 As shown, in some examples of this embodiment, the solder ribbon gap 2101 may pass through two opposite sides of the solder ribbon clamp 210 .

[0036] Combine Figure 1 and Figure 2 As shown, in some examples of this embodiment, the gap width of the welding ribbon clamp 2101 is adjustable. Providing a welding ribbon clamp 2101 with an adjustable gap width allows the welding ribbon fixture 210 to be suitable for welding ribbons of various sizes and shapes. Furthermore, in actual use, the gap width of the welding ribbon clamp 2101 can be adjusted to a wider width to facilitate placement of the welding ribbon in the welding ribbon clamp 2101, and then the gap width of the welding ribbon clamp 2101 can be narrowed to secure the welding ribbon.

[0037] Further, refer to Figure 2 As shown, in some examples of this embodiment, the soldering ribbon clamp 210 may include a first clamping block 211 and a second clamping block 212 that are spaced apart from each other, and the soldering ribbon gap 2101 may be provided between the first clamping block 211 and the second clamping block 212. Furthermore, the first clamping block 211 and the second clamping block 212 can move relative to each other, so that the gap width of the soldering ribbon gap 2101 is adjustable.

[0038] Further, refer to Figure 2 As shown, in some examples of this embodiment, the welding ribbon fixing mechanism may further include an end support plate 220, which may be connected to the ends of the first clamping block 211 and the second clamping block 212. The end support plate 220 is used to fix the positions of the first clamping block 211 and the second clamping block 212. Furthermore, the first clamping block 211 and / or the second clamping block 212 may be movably connected to the end support plate 220, so that the first clamping block 211 and the second clamping block 212 can move relative to each other.

[0039] Reference Figure 2 As shown, in some examples of this embodiment, in the welding ribbon fixing mechanism, there may be two end support plates 220 , and the two end support plates 220 are respectively arranged at both ends of the first clamping block 211 and the second clamping block 212 .

[0040] Figure 3 for Figure 1 Schematic diagram of the battery fixing mechanism in FIG. Figure 1 and Figure 3 As shown, in some examples of this embodiment, the battery fixing mechanism includes a battery accommodating member 110 and a lifting member 120. The battery accommodating member 110 has a battery accommodating slot for the solar cell to be set. The battery station 101 is set in the battery accommodating slot. The lifting member 120 is used to drive the solar cell located in the battery accommodating slot. It can be understood that in actual use, the solar cell can be set in the battery accommodating slot first, and then the lifting member 120 is used to drive the solar cell to move upward to reach the preset battery station 101, and to have a more appropriate distance between the solar cell and the soldering ribbon located at the soldering ribbon station 201, so as to facilitate soldering the soldering ribbon to the solar cell. By providing the lifting member 120, the placement process of the solar cell can be simplified, and the distance between the solar cell and the soldering ribbon can be adjusted to improve the accuracy of welding.

[0041] Combine Figure 1 and Figure 3 As shown, in some examples of this embodiment, the battery accommodating member 110 includes a limiting top plate 111 and a supporting bottom plate 112 that are relatively and spaced apart. The battery accommodating groove is arranged between the limiting top plate 111 and the supporting bottom plate 112. The spacing between the supporting bottom plate 112 and the limiting top plate 111 is adjustable, and the supporting bottom plate 112 is connected to the lifting member 120. It can be understood that the lifting member 120 is connected to the supporting bottom plate 112, so the lifting member 120 can drive the solar cell to move upward by raising the supporting bottom plate 112. The limiting top plate 111 at the top can limit the rising range of the solar cell, ensuring that the solar cell can accurately reach the preset battery station 101.

[0042] Combine Figure 1and Figure 3 As shown, in some examples of this embodiment, a welding gap 1110 is provided in the limiting top plate 111, and the welding gap 1110 is used to expose the electrodes of the solar cell, and the welding strip station 201 is provided above the welding gap 1110. It can be understood that the welding gap 1110 can be used as a reference structure when placing the solar cell and the welding strip, and is used to position the welding strip and the solar cell. In the actual welding process, the electrode of the solar cell is aligned with the welding gap 1110, and the welding strip is aligned with the welding gap 1110, which can ensure that the welding strip and the solar cell are accurately aligned. Furthermore, the welding part 310 can also be provided directly above the welding gap 1110 to weld the welding strip and the solar cell after the alignment is completed.

[0043] Combine Figure 1 and Figure 3 As shown, in some examples of this embodiment, there are multiple welding gaps 1110, and the multiple welding gaps 1110 are arranged in parallel. There are also multiple welding parts 310, and the multiple welding parts 310 are arranged corresponding to the multiple welding gaps 1110. Furthermore, there can also be multiple corresponding welding ribbon stations 201. It can be understood that by providing multiple welding gaps 1110 and multiple welding parts 310, multiple welding ribbons can be welded to solar cells simultaneously, improving welding efficiency.

[0044] Combine Figure 1 and Figure 3 As shown, in some examples of this embodiment, the battery container 110 may further include two side panels 113 disposed opposite each other, the limiting top panel 111 and the supporting bottom panel 112 disposed between the two side panels 113, and the battery receiving slot is also located between the two side panels 113. Furthermore, the limiting top panel 111 may be fixedly connected to the two side panels 113, and the supporting bottom panel 112 may be movably disposed between the two side panels 113, so that the lifting member 120 can drive the supporting bottom panel 112 to move between the two side panels 113.

[0045] Combine Figure 1 and Figure 3 As shown, in some examples of this embodiment, the tensile test piece welding device further includes a tensile test moving mechanism. The tensile test moving mechanism is used to drive the battery fixing mechanism to move along the extension direction of the ribbon welding station 201. It can be understood that in actual use, the battery fixing mechanism fixes the solar cell on the battery station 101, and the tensile test moving mechanism drives the battery fixing mechanism to move, thereby indirectly driving the solar cell to move along the extension direction of the ribbon welding station 201, thereby causing relative movement between the welded solar cell and the ribbon, and enabling the tensile force between the solar cell and the ribbon to be tested directly after welding is completed.

[0046] Furthermore, the tensile test mobile mechanism may include a base 420 and a roller 410 , the battery fixing mechanism may be arranged on the base 420 , and the base 420 may be arranged on the roller 410 , and the battery fixing mechanism may be driven to move by moving the roller 410 .

[0047] Figure 4 for Figure 1 Schematic diagram of the welding mechanism in the structure. Figure 1 and Figure 4 As shown, in this embodiment, the welding mechanism includes a welding member 310 and a welding driver 320. The welding driver 320 is used to drive the welding member 310 to move along the ribbon welding station 201. The welding member 310 is used to weld the ribbon located on the ribbon welding station 201 to the solar cell located on the cell station 101. Furthermore, the welding member 310 can be an electric soldering iron.

[0048] Further, combined with Figure 1 and Figure 4 As shown, in some examples of this embodiment, the welding drive member 320 may include a moving part 321 and a guide part 322, the extension direction of the guide part 322 may be the same as the extension direction of the welding strip station 201, the moving part 321 may be arranged on the guide part 322 and can move along the guide part 322, the welding part 310 is connected to the moving part 321, and can move along the guide part 322 along with the moving part 321.

[0049] In some examples of this embodiment, there may be two guide members 322, with both ends of the movable member 321 respectively disposed on the two guide members 322. Furthermore, each guide member 322 may include two guide rails spaced apart, with the movable member 321 disposed between the two guide rails.

[0050] Combine Figure 1 and Figure 4 As shown, in some examples of this embodiment, there can be multiple welding parts 310, and the multiple welding parts 310 can all be connected to the same movable component 321, that is, one movable component 321 can drive multiple welding parts 310 to move at the same time, so that the multiple welding parts 310 can weld multiple welding strips to the solar cells at the same time.

[0051] Reference Figure 1 As shown, in some examples of this embodiment, the tensile test piece welding device further includes a ribbon splitting mechanism 500, which is disposed on one side of the ribbon fixing mechanism and is used to split the ribbon. It will be appreciated that the ribbon splitting mechanism 500 can be provided to split the ribbon after welding is completed, removing the portion of the ribbon secured by the ribbon fixing mechanism, and retaining the remaining ribbon for subsequent welding, thereby avoiding ribbon waste.

[0052] In some examples of this embodiment, the ribbon cutting mechanism 500 may be disposed on a side of one ribbon clamp 210 away from the other ribbon clamp 210 .

[0053] In order to facilitate the description of the working mode of the above-mentioned tensile test piece welding device, the present invention also provides Figure 5 , Figure 5 For Figure 1 Schematic diagram of the cross-sectional structure of the welding ribbon 20 and the solar cell 10 in the tensile test piece welding device. Figure 5 As shown, the soldering ribbon 20 is fixedly disposed in the soldering ribbon station 201 , and the solar cell 10 is fixedly disposed in the cell station 101 .

[0054] Combine Figure 1 and Figure 5 As shown, in some examples of this embodiment, in the two ribbon clamps 210, the ribbon gap 2101 of one ribbon clamp 210 is set flush with the ribbon station 201, and the ribbon gap 2101 of the other ribbon clamp 210 is set above the side of the ribbon station 201. Figure 1 and Figure 5 In the illustrated orientation, the ribbon gap 2101 on the left side of the ribbon station 201 is flush with the ribbon station 201, while the ribbon gap 2101 on the right side of the ribbon station 201 is positioned above the right side. Accordingly, the portion of the ribbon 20 on the ribbon station 201 is flush and horizontal with the portion of the ribbon 20 on the left side, while the portion of the ribbon 20 on the right side intersects the portion of the ribbon 20 on the ribbon station 201 at an angle.

[0055] exist Figure 5 In the figure, the dashed arrow adjacent to the welding member 310 indicates the direction of movement of the welding member 310 during welding, i.e., the welding member 310 moves from one end of the ribbon welding station 201 to the other, while simultaneously welding the ribbon 20 located on the ribbon welding station 201 to the solar cell 10. The dashed arrow adjacent to the tensile test mechanism indicates its direction of movement during the tensile test, i.e., the tensile test mechanism moves toward the right. It will be understood that this movement direction is the same as the extension direction of the ribbon welding station 201. During the actual tensile test, a tensile force gauge can be used to apply tension to the tensile test mechanism to measure the tension of the ribbon 20.

[0056] Further, in Figure 1 and Figure 5 In the figure, the portion of the soldering ribbon 20 arranged on the right side is inclined to intersect with the portion of the soldering ribbon 20 located on the soldering ribbon station 201. When the tensile test moving mechanism moves toward the right side, the influence of the friction between the soldering ribbon 20 on the right side and the solar cell 10 can be avoided, thereby making the measured tensile result more accurate.

[0057] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
