[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] like Figure 1 As shown, the photovoltaic module production line according to the embodiment of the present invention includes a first slicing component 1, a second slicing component 2, a detection component 3, a storage component 5, a gluing component 6, a stacking platform 7 and a positioner 8. The first slicing component 1 is used to cut the battery original sheet into full sheets, and the second slicing component 2 is connected to the first slicing component 1 and is used to cut the full sheet into battery sheets of different specifications.

[0019] The number of detection components 3 is equal to the number of specifications of the battery cells, and the detection components 3 are used to detect battery cells of corresponding specifications. The first slicing component 1 and the second slicing component 2 are both connected with detection components 3, and each detection component 3 can detect battery cells of different specifications including full slices. The number of second slicing components 2 is the same as the number of specifications of half slices, that is, the number of detection components 3 is equal to the sum of the number of first slicing components 1 and the number of second slicing components 2.

[0020] The number of storage components 5 is equal to and corresponds to the number of detection components 3. The storage components 5 are connected to the corresponding detection components 3 and are used to store battery cells of corresponding specifications. The number of gluing components 6 is equal to and corresponds to the number of storage components 5. The gluing components 6 are connected to the corresponding storage components 5 and are used to glue battery cells of corresponding specifications. The stacking platform 7 is connected to each of the multiple gluing components 6. The stacking platform 7 is used to stack battery cells of different specifications. The positioner 8 is installed on the stacking platform 7 and is used to position battery cells of different specifications.

[0021] The photovoltaic module production line according to the embodiment of the present invention can simultaneously produce battery cells of various specifications including full cells by setting up the first slicing component 1 and the second slicing component 2, and when battery cells of other specifications other than full cells need to be formed, the cut and formed full cells only need to be transported from the first slicing component 1 to the second slicing component 2 for re-cutting, thereby eliminating the need to set up multiple loading components matching battery cells of different specifications, thereby reducing the cutting cost of battery cells of various specifications.

[0022] In some embodiments, Figure 1 As shown, the photovoltaic module production line also includes a plurality of waste boxes 4, the number of waste boxes 4 is equal to and corresponds to the number of detection components 3, and the waste boxes 4 are used to receive unqualified cells of corresponding specifications. Specifically, the waste box 4 is located beside the corresponding detection component 3, and the detection component 3 is located downstream of the corresponding first slicing component 1 / second slicing component 2, and upstream of the storage component 5.

[0023] In some embodiments, the photovoltaic module production line also includes a control terminal, and each of the storage components 5 is equipped with a detector for detecting the number of battery cells of corresponding specifications. Each of the multiple detectors is electrically connected to the control terminal, and the control terminal controls the first slicing component 1 and the second slicing component 2 to cut and form battery cells of set specifications according to the value L detected by the detector.

[0024] Specifically, the thicknesses of battery cells of different specifications are the same, and the battery cells of corresponding specifications on each storage assembly 5 are stacked in sequence in the thickness direction, wherein: D is the total height of the stacked cells, d is the thickness of the corresponding cell, and m is the measurement error.

[0025] That is, by using the sensor in the detector to detect the total height D of the multiple stacked battery cells in real time, the detector can directly obtain the number L of the stacked battery cells, and by introducing a measurement error m, it is convenient to obtain an integer L value.

[0026] If the number of battery cells on the corresponding storage component 5 is less than the set number, the control terminal can control the first slicing component 1 / the second slicing component 2 to change parameters to cut and form the battery cells, thereby ensuring a balance in the number of battery cells of various specifications.

[0027] In some embodiments, 0.9≤m≤1.1. That is, within the error range, the value detected by the detector has only one integer value, which is L, and the value detected by the detector has higher accuracy.

[0028] In some embodiments, the number of full cells in the photovoltaic module is X and the number of single-specification cells in the remaining specifications is Y. n The ratio is Z n, the number of full cells x on the storage component 5 and the number of other specification cells y on the storage component 5 n The ratio is z n Among them, z n =kZ n , n is the number of specifications of battery cells other than full cells, and the control terminal controls the first slicing component 1 and the second slicing component 2 to cut and form battery cells of corresponding specifications according to the size of k.

[0029] Therefore, under the control of the control terminal, the number of full cells x on the storage component 5 and the number of other specification cells y on the storage component 5 n The ratio of n It is always kept within the set range, thus ensuring that each cell meets the stacking requirements of the photovoltaic module.

[0030] For example, when the number of cell sheets other than full sheets in a photovoltaic module is two, that is, when n=2, the number of cell sheets of two specifications in the photovoltaic module is Y1 and Y2, the ratio of X to Y1 is Z1, and the ratio of X to Y2 is Z2. The number of cell sheets on the two storage components 5 is y1 and y2, the ratio of x to y1 is z1, and the ratio of x to y2 is z2. Among them, when both specifications of cell sheets need to be cut and formed, the priority cutting order is determined according to the maximum offset value of z1 / z2 relative to Z1 / Z2, so as to continuously adjust in a cycle.

[0031] In some embodiments, when k < 1, the first slicing assembly 1 cuts into full sheets, and when k > 2.5, the second slicing assembly 2 cuts the full sheets into cells of corresponding specifications. The photovoltaic assembly production line also includes a circulating conveyor, which connects the first slicing assembly 1 and the second slicing assembly 2, and the circulating conveyor is used to transport the full sheets cut by the first slicing assembly 1 to the second slicing assembly 2.

[0032] k is the slicing adjustment factor. Based on the number of full slices, when the stock of a certain specification of battery cells is insufficient (k>2.5), the circulating conveyor is automatically started, and the circulating conveyor transfers the full slices cut by the first slicing component 1 to the corresponding second slicing component 2, thereby realizing the cutting of battery cells of corresponding specifications. The cut slices are sent to the storage component 5 after being inspected by the corresponding inspection component 3, and sent to the waste box 4 if they are unqualified. When the stock of battery cells of this specification is sufficient for the adjustment factor (k<1), the circulating conveyor is stopped.
