Currently, PV modules are gradually becoming more widely used to power electrical equipment or transmit electrical energy to the grid. In the production process of PV modules, solar panels are made up of spliced ​​cells. The electrodes of two adjacent cells are connected, and the adjacent cells need to be welded together using welding ribbons.

[0027] Example 1, combined with Figure 1 and Figure 2 Explanation:

[0028] 1. A battery cell stacking welding device, characterized in that it comprises: a support platform 1 and a welding gun device 2, the welding gun device 2 being disposed on the support platform 1, a linear guide rail 3 being disposed on the support platform 1, the welding gun device 2 being disposed at one end of the linear guide rail 3, a linear motor 4 being slidably disposed on the linear guide rail 3, a welding platform 5 being disposed on the linear motor 4, and a stacking welding limiting component 6 being disposed on the welding platform 5, the stacking welding limiting component 6 being used to place a first battery cell 91, a second battery cell 92 and a welding strip 93.

[0029] The device also includes a controller 7, which is mounted on the support platform 1.

[0030] By setting up the superimposed welding limiting component 6, the first battery cell 91, the second battery cell 92, and the welding strip 93 can be quickly set and limited, which facilitates welding by the subsequent welding gun device 2; by setting up the welding gun device 2, superimposed welding can be facilitated; by setting up the linear guide rail 3 and the linear motor 4, the degree of automation is improved; by setting up the linear motor 4, the superimposed welding limiting component 6 can be driven to move linearly; by setting up the welding platform 5, the superimposed welding limiting component 6 can be installed; and by setting up the controller 7, the operation of the device can be controlled.

[0031] Example 2, based on Example 1, combined with... Figure 3 Explanation:

[0032] The stacked welding limiting assembly 6 includes: a first battery cell support block 61, a second battery cell support block 62, a limiting block 63, and a side limiting block 64. The first battery cell support block 61 is fixedly installed on the welding platform 5. The second battery cell support block 62 is located on one side of the first battery cell support block 61. The limiting block 63 is located on the other side of the first battery cell support block 61. Two sets of side limiting blocks 64 are provided, and the two sets are located on both sides of the first battery cell support block 61, the second battery cell support block 62, and the limiting block 63.

[0033] A first battery cell support block 61 is provided to support the first battery cell 91, and a second battery cell support block 62 is provided to support the second battery cell 92. The first battery cell support block 61 and the second battery cell support block 62 are used together to support the welding strip 93. A limiting block 63 is provided to limit the first battery cell 91 to prevent it from slipping. A side limiting block 64 is provided to facilitate the side limiting of the first battery cell 91 and the second battery cell 92.

[0034] Example 3, based on Example 2, combined with Figure 4 Explanation:

[0035] The upper side of the first battery cell support block 61 includes a first inclined surface 611 and a second inclined surface 612. The first inclined surface 611 and the second inclined surface 612 are vertically arranged. The first inclined surface 611 cooperates with the side limiting block 64 to limit the first battery cell 91. The second inclined surface 612 cooperates with the second battery cell support block 62 to limit the welding ribbon 93 and the second battery cell 92. The second inclined surface 612 is used to prevent the second battery cell 92 and the welding ribbon 93 from slipping off.

[0036] The upper side of the side limiting block 64 includes a third inclined surface 641, which is perpendicular to the first inclined surface 611. The third inclined surface 641 is used to prevent the first battery cell 91 from slipping off the first inclined surface 611.

[0038] The first inclined surface 611 has an inclination angle of 30 degrees. If the inclination angle is too large or too small, it will be inconvenient for the welding gun device 2 to stack and weld the first battery cell 91, the second battery cell 92 and the welding strip 93.

[0039] Example 4, based on Example 3, combined with Figure 5 Explanation:

[0040] The device also includes a preheating component, which includes a hot air blower 81, a duct 82, and an air outlet hood 83. The hot air blower 81 is fixedly installed on one side of the support platform 1. The hot air blower 81 is located upstream of the welding torch device 2. The output end of the hot air blower 81 is connected to the air outlet hood 83 through the duct 82. The opening of the air outlet hood 83 is aligned with the overlapping welding area.

[0041] With this setup, hot air can be generated by the hot air blower 81, and the hot air can be guided by the air duct 82 and the air outlet hood 83, so that the hot air is blown toward the welding strip for preheating.

[0042] The working principle of this utility model is as follows: In use, the second battery cell 92 is first placed on the fourth inclined surface 621, so that the second battery cell 92 adheres to the fourth inclined surface 621 and the second inclined surface 612 under the action of gravity. Then, the welding ribbon 93 is placed on the upper side of the second battery cell 92, so that the welding ribbon 93 adheres to the second inclined surface 612. Next, the first battery cell 91 is placed on the first inclined surface 611, so that the first battery cell 91 adheres to the first inclined surface 611 and the third inclined surface 641 under the action of gravity. At this time, the lower side of the first battery cell 91 is also adhered to the upper side of the welding ribbon 93. After placement is complete, the controller 7 and the linear motor are started. 4. First, the first battery cell 91, the second battery cell 92, and the welding ribbon 93 are moved to the preheating component for preheating. Then, the first battery cell 91, the second battery cell 92, and the welding ribbon 93 are moved to the welding gun device 2 for welding. After welding is completed, the linear motor 4 resets, and the operator removes the stacked first battery cell 91, the second battery cell 92, and the welding ribbon 93. This utility model has a reasonable structure and is easy to use. By setting the stacking limit component 6, the first battery cell 91, the second battery cell 92, and the welding ribbon 93 can be quickly set and limited, which facilitates the subsequent welding by the welding gun device 2.
