Description

Technical Field

[0001] The present invention belongs to the technical field of solar cells, and particularly relates to a battery chip auxiliary separator. Background Art

[0002] The back contact battery (BC) is a solar cell combined with multiple technical routes. Its electrodes are located on the back of the battery, and there is no metal grid line blocking on the front. The advantage of this design can ensure that the front of the battery fully receives sunlight, while reducing the current transmission path and resistance, thereby effectively improving the performance of the battery. However, this structure also has obvious disadvantages. For example, when BC battery chips are stacked, the front of the battery chip contacts the back of the next battery chip. There are raised metal grid lines on the front, while the back surface is smooth. When the two battery chips contact, the metal grid lines are very likely to cause scratches, even cracks or fragments on the back of the battery chip, resulting in a significant reduction in the shipping rate and an increase in production costs.

[0031] Please refer toFigure 1 , 4 and 5, the auxiliary separator for solar cells includes: a solar cell adsorption unit, arranged above the film laminating unit, for adsorbing or releasing the adsorption of solar cells; a film laminating unit, arranged above the solar cell storage box, for fixing and pulling the film 10 to move, so that the film 10 is laid under the solar cell 6, and after determining that the solar cell 6 lands on the film 10, releasing the fixation of the film 10, so that the combination of the film 10 and the solar cell 6 falls into the solar cell storage box.

[0032] Here, the solar cell 6 is a BC solar cell and is stored in the solar cell storage unit. The solar cell storage unit can be the production conveyor belt of solar cells. Exemplarily, the solar cell adsorption unit adsorbs the solar cell 6 from the production conveyor belt of solar cells and releases the adsorption of the solar cell 6 above the film laminating unit.

[0033] Please refer to Figure 2 , 4 and 5, the solar cell adsorption unit includes: an adsorption module and a second support module 4; the adsorption module and the second support module 4 are movably connected, and the second support module 4 is arranged on one side of the film laminating unit; the adsorption module can move up and down relative to the second support module 4, for adsorbing or releasing the adsorption of solar cells.

[0034] Here, the second support module 4 includes: a first support rod 41 and a second support rod 42; the first support rod 41 is arranged on one side of the film laminating unit, one end of the second support rod 42 is movably connected with the adsorption module, and the other end is connected with the end of the first support rod 41 far from the film laminating unit. The first support rod 41 and the second support rod 42 are perpendicular to each other.

[0035] Here, the adsorption module includes: a suction cup 5 and a fixing rod 1 which are fixedly connected; the fixing rod 1 is movably connected with the second support module 4. Specifically, the fixing rod 1 is movably connected with the first support rod 41, and the second support rod 42 is rotatably arranged on the connecting bar 8; Exemplarily, the second support rod 42 rotates clockwise to the production line of the solar cell 6, a convex block is arranged on the first support rod 41, a slide rail is arranged on the fixing rod 1, by clamping the convex block in the slide rail, electrically controlling the convex block to slide down in the vertical slide rail, so as to drive the fixing rod 1 and the suction cup 5 to approach and adsorb the solar cell 6, and then electrically controlling the convex block to rise in the vertical slide rail, along with the counterclockwise rotation of the second support rod 42, the solar cell 6 is located above the film 10. Here, the suction cup 5 is an electric suction cup, and the solar cell 6 is a BC solar cell; the suction cup 5 contacts the side of the solar cell 6 covered with metal grid lines.

[0036] Please refer to Figure 3 , 4-6, the film laminating unit includes: a film supply module, a film clamping module, and a first support module; the first support module is disposed on the film clamping module, and the film supply module is disposed on one side of the film clamping module; the solar cell adsorption unit is disposed on the first support module; the film supply module is configured to provide a film 10 to the film clamping module; the film clamping module is configured to clamp one side of the film 10 to drag the film 10 to move below the solar cell 6, and after reaching below the solar cell 6, clamp the other side of the film 10.

[0037] Here, the film supply module includes: a cutting sub-module 9 and a film storage sub-module 7; the cutting sub-module 9 and the film storage sub-module 7 are arranged side by side on one side of the film clamping module; the cutting sub-module 9 is configured to monitor the film length when the film clamping module drags the film 10 stored in the film storage sub-module 7, and after the film length reaches a preset length, cut off the connection between the film and the film storage sub-module. In a possible implementation, the cutting sub-module 9 is a laser cutter; the film storage sub-module 7 is in a cylindrical shape.

[0038] In a possible implementation, the second support module 4 is also connected to the cutting sub-module 9. Specifically, the second support module 4 is respectively disposed at the midpoints of the connecting bar 8 in the first support module and the cutting sub-module 9.

[0039] Exemplarily, a technician pulls out the film from the film storage sub-module, fixes one end of it on the film clamping module, and uses the film clamping module to pull the film 10 to a preset position. During this period, the cutting sub-module 9 is used for real-time monitoring. After the pulled film length is greater than the preset length and before the cutting sub-module 9 cuts off the film 10, the other end of the film 10 is intelligently fixed on the film clamping module. It should be understood that the film length being greater than the preset length can ensure a surplus, avoiding incomplete fitting of the solar cell 6 and the film 10, or holes in the film 10 attached to the solar cell 6.

[0040] Please continue to refer to Figure 3-5 As shown in FIGS. 6 and 7, the first support module includes: a first bracket 21, a second bracket 22, and a connecting bar 8; the first bracket 21 and the second bracket 22 are symmetrically arranged, and both ends of the connecting bar 8 are respectively connected to one end of the first bracket 21 and one end of the second bracket 22; and, sliding sub-modules are disposed on both the first bracket 21 and the second bracket 22. Here, the first bracket 21 and the second bracket 2 form a bracket 2; the sliding sub-module is a rectangular conveyor belt or an oval conveyor belt. For example, Figure 7 the conveyor belt 221 disposed on the first bracket 21 in FIG. 6.

[0041] Here, the film clamping module includes: a plurality of tapered pestles 3. For example, Figure 5The first conical pestle 31 and the second conical pestle 32 in it. The cell auxiliary separator further includes: a control module (not shown in the figure); one end of a plurality of conical pestles 3 is movably clamped in the sliding sub-module; the plurality of conical pestles 3 and the sliding sub-module are respectively electrically connected to the control module; the sliding sub-module is configured to drive the plurality of conical pestles 3 to move relative to the first bracket 21 and the second bracket 22 in response to a first control instruction of the control module; the plurality of conical pestles 3 are configured to slide up and down relative to the sliding sub-module in response to a second control instruction of the control module to clamp the film 10 or release the clamping of the film 10.

[0042] Here, please refer to Figure 6 , the conical pestle 3 is composed of two parts. The part clamped in the sliding sub-module is a hollow cylinder, and the part used to pierce into the film is a conical needle. The conical needle can retract and extend in the hollow cylinder in response to the second control instruction. Moreover, the number and the setting positions of the conical pestles 3 provided on the first bracket 21 and the second bracket 22 are the same, and are at least 2. As Figure 5 shown, when the number of the conical pestles 3 on one bracket is 2, the first conical pestle 31 provided on the first bracket 21 is located at the starting end, that is, at the position where the first bracket 21 is far from the cutting sub-module 9, and the second conical pestle 32 on the first bracket 21 is located at the position close to the cutting sub-module 9. Moreover, the first conical pestle 31 provided on the first bracket 21 and the second conical pestle 32 provided on the second bracket 22 extend or retract the conical needles synchronously.

[0043] In actual work, the adsorption module in the cell adsorption unit adsorbs the cell 6 from the conveyor belt of the production line above the cell storage box. Among them, the back surface of the cell 6 faces the film 10; the technician pulls out the film 10 from the film storage sub-module 7 and fixes one end of it on the first conical pestle 31 just near the film storage sub-module 7. In response to the first control instruction, the film 10 is driven to slide in the conveyor belt 221 until the pulled film length is greater than the preset length, and then the cutting sub-module 9 cuts off the connection between the film 10 and the film storage sub-module 7; the other end of the film 10 is automatically pierced and fixed by the sliding second conical pestle 32; at this time, the film 10 is located above the cell 6; the adsorption module releases the adsorption of the cell 6 and blows an appropriate amount of air, and the cell 6 falls to make its back surface fit with the film 10, and under the influence of gravity, drives the film 10 to fall off from the first conical pestle 31 and the second conical pestle 32 and fall into the cell storage box; at the same time, the adsorption module continues to adsorb a new cell 6 from the conveyor belt of the production line to repeat the above steps. It should be noted that when the film in the film storage sub-module 7 is used for the first time, it needs to be assisted by the technician to be pulled out. At other times, a new film can be pulled out by the movement of the conical pestle.

[0044] In view of the problem that the existing stacking method of BC solar cells easily leads to a low shipping rate of solar cells, the present invention proposes a solar cell auxiliary separator. This device can adsorb the solar cells by means of a solar cell adsorption unit so that the side to be laminated faces the lamination unit, and use the lamination unit to attach a wear-resistant film to the solar cells, ensuring that adjacent solar cells do not rub against each other during the stacking of solar cells, avoiding problems such as scratches, cracks or fragments, greatly improving the shipping rate of solar cells and reducing the production cost.

[0045] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present invention.
