[0023] 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.

[0024] like Figure 1As shown, the multi-specification solar cell photovoltaic module production line according to an embodiment of the present invention includes a slicing component 1, a first storage component 2 and a detection component 6, as well as a second storage component 4, a third storage component 9, a gluing component 8 and a control terminal 5 connected in sequence. The slicing component 1 can cut the original cell into full sheets, and can cut the full sheets into cells of different specifications. The detection component 6 is used to detect full sheets and cells of different specifications, and the first storage component 2 is used to store full sheets. The number of the second storage components 4 is equal to the number of specifications of cells of different specifications cut and formed by the slicing component 1 and corresponds one to one. The second storage component 4 is connected between the slicing component 1 and the detection component 6 and is used to store cells of corresponding specifications.

[0025] The number of third storage components 9 is equal to the sum of the number of first storage components 2 and second storage components 4 and corresponds one to one. The third storage components 9 are connected to the detection component 6 and are used to store the corresponding full slices or various specifications of battery slices. The glue component 8 is connected to each of the plurality of third storage components 9. The control terminal 5 is electrically connected to the third storage component 9 and the glue component 8 respectively. The control terminal 5 is used to control the battery slices of different specifications to go to the glue component 8 according to the layout of the photovoltaic module, and control the glue component 8 to glue the corresponding size of the battery slice.

[0026] According to the multi-specification cell photovoltaic module production line of the embodiment of the present invention, when more specifications of cells need to be cut, only the second storage component 4 and the third storage component 9 for storing the increased specifications of cells need to be added, and the multi-specification cell photovoltaic module production line has stronger adaptability. Moreover, only one detection component 6 is needed to detect cells of different specifications, and the detection cost is lower.

[0027] In some embodiments, the multi-specification cell photovoltaic assembly production line further includes a circulating conveyor 3, the circulating conveyor 3 is connected to the first storage assembly 2 and the slicing assembly 1, the control terminal 5 is electrically connected to the circulating conveyor 3 and the first storage assembly 2, and the circulating conveyor 3 is used to convey the full slices on the first storage assembly 2 to the slicing assembly 1. That is, when the number of half slices is small and the number of full slices on the first storage assembly 2 is too large, the full slices on the first storage assembly 2 can be conveyed to the slicing assembly 1 for slicing, further ensuring that the full slices and half slices maintain a set ratio range.

[0028] Moreover, when it is necessary to form battery cells of other specifications besides full sheets, the cut and formed full sheets only need to be transported to the slicing assembly 1 through the circulating conveyor 3 for further cutting. Therefore, there is no need to set up multiple loading assemblies matching battery cells of different specifications, thereby reducing the cutting cost of battery cells of various specifications.

[0029] In some embodiments, the control terminal 5 is electrically connected to the slicing assembly 1 and the circulating conveyor 3 to control the slicing assembly 1 to cut and form cells of set specifications. Therefore, the multi-specification cell photovoltaic assembly production line according to this embodiment can automatically complete the cutting of cells of different specifications.

[0030] Specifically, the control terminal 5 can control the slicing assembly 1 to cut various specifications of battery cells including full cells, and can also control the circulating conveyor 3 to work so as to transfer the full cells on the first storage assembly 2 to the slicing assembly 1. When full cells need to be made, the control terminal 5 controls the slicing assembly 1 to cut the battery cells loaded by the loading assembly into full cells; when other specifications of battery cells need to be made, the control terminal 5 controls the circulating conveyor 3 to work, and the control terminal 5 controls the slicing assembly 1 to change parameters so as to be able to cut the full cells into battery cells of set specifications.

[0031] In some embodiments, the multi-specification solar cell photovoltaic module production line further includes a waste box 7. The waste box 7 is connected to the detection component 6 and is used to receive unqualified solar cells.

[0032] In some embodiments, the detection component 6 includes labels that match the different specifications of battery cells required by the photovoltaic module. The control terminal 5 is electrically connected to the detection component 6. The control terminal 5 controls the detection component 6 to switch different labels based on pixel edge detection of battery cells of different specifications to facilitate the detection of whether the battery cells are complete.

[0033] That is, the detection component 6 includes labels of various specifications of battery cells including full cells. When the slicing component 1 cuts battery cells of corresponding specifications, the control terminal 5 also controls the detection component 6 to switch to the labels corresponding to the battery cells of the specifications. At this time, the detection of the battery cells of the corresponding specifications is realized through PL (photoluminescence) detection or EL (electroluminescence) detection. In this way, one detection component 6 can detect battery cells of different specifications, reducing the detection cost of battery cells of different specifications.

[0034] In some embodiments, Figure 2 As shown, the detection component 6 includes a detection platform 61 and a camera 62. The detection platform 61 is an EL detection platform or a PL detection platform. The camera 62 is locked above the detection platform 61 and is used to capture EL images or PL images of battery cells of different specifications on the detection platform 61.

[0035] The camera 62 is fixed above the inspection platform 61, and the distance between the camera 62 and the inspection platform 61 is locked and unchanged. The ratio between the image of the battery cell taken by the camera 62 and the actual size of the battery cell is fixed, so that the control terminal 5 can easily obtain the actual size of battery cells of different specifications based on the image of the battery cell, and then the downstream conveyor can transport the battery cells of corresponding specifications to the set position on the stacking platform 10, so as to ensure the production efficiency of the photovoltaic modules.

[0036] In some embodiments, the detection component can record the number L of qualified battery cells of various specifications. If the number of battery cells of corresponding specifications is less than the set number, the control terminal 5 can control the slicing component 1 to change the parameters to cut and shape the battery cells, thereby ensuring the balance of the number of battery cells of various specifications.

[0037] 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 third storage component 9 and the number of other specification cells y on each third storage component 4 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 5 controls the slicing component 1 to cut and form battery cells of corresponding specifications according to the size of k. Therefore, under the control of the control terminal 5, the number of full cells x on the third storage component 9 and the number of battery cells of other specifications y on each third storage component 9 are 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.

[0038] For example, when the number of cell sheets other than full sheets in the photovoltaic module is two, that is, when n=2, the number of cell sheets of the 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 third storage components 9 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.

[0039] In some embodiments, when k is less than 1, the slicing assembly 1 cuts the whole slice into cells; when k is greater than 2.5, the slicing assembly 1 cuts the whole slice into cells of corresponding specifications.

[0040] k is the slicing adjustment factor, which is 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 3 is automatically started, and the information is fed back to the slicing component 1. The slicing component 1 adjusts the slicing program and slicing width, and cuts the circulating battery cells into corresponding specifications. The cut slices are sent to the second storage component 4 for subsequent inspection, gluing and lamination. When the stock of battery cells of this specification exceeds the adjustment factor (k<1), the circulating conveyor 3 is stopped, and the information is fed back to the slicing component 1. The slicing component 1 adjusts the slicing program and slicing width, and continues to cut the full battery cells. This cycle continues.

[0041] In some embodiments, the multi-specification cell photovoltaic module production line also includes a stacking platform 10 and a positioner 11. The stacking platform 10 is connected to the glue assembly 8 and is used to stack cells of different specifications. The positioner 11 is installed on the stacking platform 10 and is used to position cells of different specifications.

[0042] In some embodiments, the glue application assembly 8 includes a plurality of glue application platforms, and the glue application platforms 8 correspond to the third storage assembly 9 one by one. Each glue application platform is provided with a glue application nozzle for applying glue to battery cells of corresponding specifications. Thus, full cells and half cells of different specifications are transported to the corresponding glue application platforms and glued through the glue application nozzles, thereby realizing the glue application operation with high glue application accuracy.

[0043] Alternatively, the gluing assembly 8 has a gluing head for gluing battery cells of different specifications, so that one gluing assembly 8 can achieve gluing of battery cells of different specifications, and the gluing cost is lower.

[0044] like Figure 2 and Figure 3 As shown, the embodiment of the present invention uses 182mm×30mm unit cells, and the upper and lower rows are connected in series in a shingled manner. Each row consists of 10 unit cells in parallel, and each photovoltaic module has a total of 60 rows. All cells in the first row use full cells, and the first and last cells in the second row use half cells. The arrangement of cells in alternate rows is the same. In this way, each photovoltaic module contains 60 half cells and 480 full cells. Full cell: half cell = 8:1.

[0045] At this time, the reaction program is set to: full slice: half slice = 8k (0.5≤k≤2). That is, when the material level of full slice and half slice: full slice: half slice ≥ 16, adjust the slicing component 1, the program is fed back to the control terminal 5, and half slice slicing is performed, until full slice: half slice ≤ 4, adjust the slicing component 1, the program is fed back to the control terminal 5, and full slice slicing is performed, and the switching is repeated.

[0046] The detection component 6 records the labels of the above two specifications of battery cells. After the cut battery cells are detected in the detection system, they are sent to the gluing component 8 by the third storage component 9 for gluing.

[0047] The glue applying component 8 has two glue applying nozzles and a glue applying platform, and the control terminal 5 instructs to apply glue lines of different lengths on two specifications of battery cells.
