Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a splicing platform device. Background Art

[0002] In the production process of solar cells, the transfer of silicon wafers or cells between upstream and downstream processes has basically been automated. The current transmission production line transports cells by placing them on the transmission belt. The cells are laid flat on the transmission belt at equal distances. When the number of cells laid on the transmission belt reaches a predetermined number, such as 9 pieces, the transmission belt moves to transfer the cells to the designated position, and then the cell on the transmission belt is lifted up by the splicing platform for the suction mechanism to pick up the material. The cell is positioned twice on the splicing platform by pins. When the cell on the splicing platform is completely picked up, the splicing platform drops and resets to wait for the next round of lifting.

[0003] The current mainstream sizes of solar cells are 182mm×91mm and 210mm×105mm. When the traditional splicing platform lifts the cell for secondary positioning, it mainly relies on positioning pins A and B. Among them, pin A is mainly used to position the long side of the cell (210mm / 182mm), and pin B is used to position the short side of the cell (105mm / 91mm). The splicing platform currently used is only suitable for cells of a certain size. In the actual production process, after producing a cell of one size, such as 210mm×105mm, when changing to another size, such as 182mm×91mm, it is necessary to modify the equipment and adjust the splicing platform of the appropriate size. Because the splicing platform has high precision requirements, the debugging work after the modification takes at least 2-3 days, which will cause the entire line equipment to stop, resulting in a large loss of production capacity and affecting corporate profits.

The first positioning component 210 has a first step 211. The second positioning component 220 has a second step 221.

The maximum straight-line distance between the first steps 211 of adjacent first positioning groups 201 along the second direction is the first distance L1. The minimum spacing between adjacent first positioning groups 201 along the second direction is the second distance L2. The first distance L1 is greater than the second distance L2. At least one second positioning group 202 is arranged between adjacent first positioning groups 201. The maximum straight-line distance between two second steps 221 in the second positioning group 202 along the first direction is the third distance L3. The minimum spacing between two second positioning components 220 in the second positioning group 202 along the first direction is the fourth distance L4. The third distance L3 is greater than the fourth distance L4. The first direction is perpendicular to the second direction.

[0037] In some embodiments, multiple groups of second positioning groups 202 are arranged between adjacent first positioning groups 201. The multiple groups of second positioning groups 202 are spaced apart along the second direction. Preferably, as shown in FIG1 , two groups of second positioning groups 202 are arranged between adjacent first positioning groups 201. The multiple groups of second positioning groups 202 can improve the positioning accuracy of the silicon wafer or battery cell 20. The distance between two adjacent groups of second positioning groups 202 is not limited.

[0038] In some embodiments, referring to Fig. 1, Fig. 1 shows two sets of first positioning groups 201. It is not difficult to understand that the first positioning member 210 can be provided with first steps 211 on both sides thereof, so that the first positioning member 210 can simultaneously assist in supporting two silicon wafers or battery cells 20, thereby improving the use efficiency of the first positioning member 210.

[0039] In some embodiments, the first positioning member 210 is detachably connected to the platform member 100. The detachable connection between the first positioning member 210 and the platform member 100 facilitates the disassembly, maintenance, and replacement of the first positioning member 210.

[0040] In some embodiments, the second positioning member 220 is detachably connected to the platform member 100. The detachable connection between the second positioning member 220 and the platform member 100 facilitates the disassembly, maintenance, and replacement of the first positioning member 210.

[0041] In some embodiments, the width of the first step 211 along the second direction is 5 mm to 12 mm, which is used to support the two ends of the silicon wafer or battery wafer 20 in the length direction.

[0042] In some embodiments, the width of the second step 221 along the first direction is 3 mm to 5 mm, which is used to support the two ends of the silicon wafer or battery cell 20 in the width direction.

[0043] In some embodiments, the platform component 100 includes a first platform 101 and a second platform 102. The first platform 101 and the second platform 102 are spaced apart along the second direction. The two first positioning components 210 on the first positioning group 201 are respectively mounted on the first platform 101 and the second platform 102, and the two second positioning components 220 on the second positioning group 202 are respectively mounted on the first platform 101 and the second platform 102. The interval between the first platform 101 and the second platform 102 can be operated by a conveyor belt and a silicon wafer or battery cell 20 on the conveyor belt. The conveyor belt runs between the first platform 101 and the second platform 102, so that the platform component 100 can be lifted directly to lift the silicon wafer or battery cell 20 on the conveyor belt for secondary positioning.

[0044] In some embodiments, the sheet splicing platform device 10 further includes a detection component 300. The detection component 300 is installed on the platform component 100 and is located between two adjacent first positioning groups 201. The detection component 300 is used to detect whether there is material on the platform component 100.

[0045] In some embodiments, the detection component 300 is a position sensor. When the detection component 300 detects that there is material on the splicing platform, the platform component 100 is driven by the driving mechanism to lift the material on the conveyor belt, such as silicon wafers and battery cells 20, and at the same time, the first positioning group 201 and the second positioning group 202 on the platform component 100 cooperate with each other to achieve secondary positioning of the silicon wafer or battery cell 20.

[0046] In some embodiments, as shown in FIG. 2 and FIG. 4 , the first distance L1 is 211 mm to 213 mm, and the first distance L1 is used to match the long side of the battery cell 20 of 210 mm×105 mm size, and the second distance L2 is 183 mm to 185 mm, and the second distance L2 is used to match the long side of the battery cell 20 of 182 mm×91 mm size. As shown in FIG. 3 and FIG. 5 , the third distance L3 is 106 mm to 108 mm, and the third distance L3 is used to match the short side of the battery cell 20 of 210 mm×105 mm size, and the fourth distance L4 is 92 mm to 94 mm, and the second distance L2 is used to match the short side of the battery cell 20 of 182 mm×91 mm size. The above distance ranges are slightly larger than the length and width of the corresponding battery cell 20, so that a certain margin space is left, so that the battery cell 20 can enter the tab assembly and the positioning component.

[0047] The above-mentioned splicing platform device 10, by setting a first positioning component 210, a second positioning component 220 and a first step 211 and a second step 221 thereon, and setting different numbers of first positioning components 210 and second positioning components 220 in the first direction and the second direction, forms a first distance L1, a second distance L2, a third distance L3 and a third distance L3, which can be adapted to and compatible with the production of 182mm×91mm size battery cells 20 and 210mm×105mm size battery cells 20. When switching the production of battery cells 20 of different sizes, it is only necessary to switch the parameters or modes on the equipment operation interface, without the need for additional equipment modification to replace the splicing platform, avoiding long-term equipment debugging, meeting the requirements of adjusting the switching production of battery cells 20 of different sizes due to market changes, without the need to re-modify the equipment production line, improving production efficiency, and maximizing corporate profits.

[0048] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
