Description

Technical Field

[0001] The utility model relates to the technical field of battery sheet processing equipment, in particular to a laser efficiency-enhancing processing streamline. Background Art

[0002] In recent years, the photovoltaic industry has developed rapidly, has passed the wild growth stage, and is putting forward higher requirements for product quality; among them, one of the key directions is to improve the photoelectric conversion efficiency of solar cells. In the prior art, the sintering process has a good passivation effect on the cell, which can improve the photoelectric conversion efficiency of the cell. At present, the common way to sinter the cell is to provide a high-temperature environment so that the metal ions and silicon atoms in the cell are heated to the eutectic temperature, and the silicon atoms are melted into the molten metal ions; wherein the high-temperature environment is provided by the sintering bin. For example, the Chinese patent with publication number CN116799098A provides a cell sintering light injection integrated device and a method of use, the equipment includes a sintering bin, the sintering bin includes a sintering zone, the sintering zone includes three heating chambers with different temperatures arranged in sequence, and the cell is heated and sintered in sequence inside the sintering bin. However, the above-mentioned method of using a sintering chamber to provide a high-temperature environment is relatively traditional and it is difficult to achieve precise control of the sintering process; moreover, direct contact between the metal and the silicon substrate may induce carrier recombination, which will lead to energy loss and thus reduce the photoelectric conversion efficiency of the battery cell.

[0003] In view of the above problems, the utility model introduces laser technology for auxiliary sintering, provides a laser efficiency enhancement platform, and can effectively improve the photoelectric conversion efficiency of the cell. Specifically: high-intensity laser is irradiated on the under-sintered cell, and a deflection voltage of 10V or more is applied at the same time, so that a local current of several amperes is generated to significantly reduce the contact resistance between the metal and the semiconductor. In principle, the current formed by the laser will be transmitted along the low contact resistance path, causing the mutual diffusion of metal and silicon, thereby reducing the contact resistance, improving the open circuit voltage and conversion efficiency; and the duration of the entire sintering process matches the carrier lifetime, and the laser stops quickly after passing, which can achieve the maximum retention of the original passivation layer and avoid the carrier recombination caused by the direct contact between the metal and silicon substrate. In essence, it is to use the highly concentrated energy and controllable characteristics of the laser to separate the two key steps of passivation layer erosion and contact formation in the high-temperature sintering process, so as to achieve further precise control of the sintering process, which has obvious advantages over traditional sintering methods.

[0004] On this basis, in order to further realize the automation and batch processing of battery cells, the utility model provides a laser efficiency-enhanced processing streamline, which can effectively improve the output speed of battery cells and better meet the development needs of the market.

The structural composition of the belt conveyor structure VI is consistent with that of the belt conveyor structure III, and will not be repeated here; for the convenience of subsequent description, the two belt conveyor structures VI are respectively recorded as the belt conveyor structure VI-a located on the left and the belt conveyor structure VI-b located on the right.

[0048] like Fig.13 As shown, the material unloading and correcting mechanism 10 includes a belt conveying structure VII, and a correcting structure IV is provided on the belt conveying structure VII. The structural composition of the correcting structure IV is consistent with the structural composition of the correcting execution component in the correcting structure II, specifically: it includes a servo motor VI50, the output end of the servo motor VI50 is indirectly connected to a synchronous wheel IV51, and a synchronous belt V52 is wound around the synchronous wheel IV51.

[0049] like Fig.14 As shown, the discharging mechanism 11 includes a belt conveyor structure VIII, and the structural composition of the belt conveyor structure VIII is consistent with that of the belt conveyor structure I, which will not be repeated here.

[0050] Based on the above structure, the working principle of this implementation is as follows:

[0051] In the fragment detection mechanism 1: the servo motor Ⅰ13 drives the synchronous pulley Ⅰ12 to rotate through the synchronous belt Ⅰ15, and then drives the belt Ⅰ14 to move by driving the drive shaft Ⅰ16 to rotate, thereby realizing the transportation of the battery cells. The industrial camera Ⅰ18 can take an image of the battery cells being transported, and then analyze and determine whether they are fragments, and according to the judgment result, the fragmentation conveyor is linked to realize the recovery of fragments or the transportation of normal pieces. The photoelectric sensor will form a reflection after irradiating light onto the reflective plate normally, but if there are battery cells flowing on the belt Ⅰ14, the reflection path of the light will be blocked. Based on this principle, the counting of the transported battery cells can be realized.

[0052] In the translation feeding mechanism 2: Since the conveyed battery cells can be counted by the industrial camera Ⅰ18, it can be further determined whether the streamline needs to be fed. If feeding is required, the translation suction cup structure is first adjusted to the top of the loading box 23 under the action of the linear motor module Ⅳ20 to facilitate material collection; after the suction cup 21 grabs the battery cell from the loading box 23, the translation suction cup structure is adjusted to the top of the belt conveyor structure Ⅱ under the action of the linear motor module Ⅳ20 again, and then the battery cell is transferred to the belt conveyor structure Ⅱ, and finally the belt conveyor structure Ⅱ is used to transport the battery cell to the next mechanism. Specifically, when the suction cup 21 grabs the battery cell, the servo motor VI28 controls the piston rod of the electric cylinder 27 to extend upward to lift the pallet 48. When the pallet 48 is lifted, the suction cup 21 grabs the battery cell on the pallet 48, and then the linear motor module IV20 drives the suction cup 21 to translate to transfer the battery cell to the belt conveyor structure II; wherein, after the optical path of the through-beam sensor 49 is blocked by the rising pallet 48, the through-beam sensor 49 sends a stop signal to the servo motor VI28, so that the piston rod of the electric cylinder 27 stops extending, thereby controlling the rising height of the pallet 48; in addition, the structure can also be directly used for off-line loading, that is, there is no need to dock with the previous mechanism, and the operator directly puts the battery cells to be processed into the loading box 23 for subsequent processing; if there are too many battery cells on the streamline causing blockage, the linear motor module IV20 can drive the suction cup to grab the battery cells on the streamline and translate them into the receiving box 47. If no material replenishment is needed, the linear motor module IV 20 and the translation suction cup 21 structure will not operate, and the normally transported battery cells will be transported to the next mechanism through the belt conveyor structure II.

[0053] When the belt conveyor structure II is conveying the battery cells, the servo motor II 25 drives the synchronous wheel II 24 to rotate, and the synchronous wheel II 24 drives the synchronous belt II 26 to move, thereby controlling the alignment fixture clamped on the synchronous belt II 26 to continuously align the battery cells.

[0054] In the fragment conveying mechanism 3: through the linear motor module Ⅰ31, the two belt conveying structures Ⅲ can be translated, and then the two belt conveying structures Ⅲ can be cross-operated. Specifically: during the streamline operation, if the fragment detection mechanism 1 detects the fragment, the linear motor module Ⅰ31 does not move, and the fragment flows directly into the fragment unloading box 4 through the belt conveying structure Ⅲ-a or belt conveying structure Ⅲ-b currently connected to the belt conveying structure Ⅱ and the fragment unloading box 4. If the fragment detection mechanism 1 does not detect the fragment, when the battery cell reaches the belt conveying structure Ⅲ-a from the belt conveying structure Ⅱ, the linear motor module Ⅰ31 will move to make the belt conveying structure Ⅲ-a and the belt conveying structure Ⅲ-b move left synchronously, based on which the belt conveying structure Ⅲ-a is connected to the belt conveying structure Ⅳ-a in the feeding conveying line 5, and the belt conveying structure Ⅲ-b is connected to the belt conveying structure Ⅱ and the fragment unloading box 4, and then the battery cell is transported from the belt conveying structure Ⅲ-a to the belt conveying structure Ⅳ-a in the feeding conveying line 5. At the same time, the belt conveyor structure III-b is responsible for continuing to receive the battery cells transmitted from the belt conveyor structure II; if the battery cells are fragments, the linear motor module I31 does not work, and the fragments directly reach the fragment unloading box 4 through the belt conveyor structure III-b; if the battery cells are intact, after the battery cells on the belt conveyor structure III-a are transported away, the linear motor module I31 will work to make the belt conveyor structure III-a and the belt conveyor structure III-b move right synchronously, based on which the belt conveyor structure III-b is docked with the belt conveyor structure IV-b in the feeding conveyor line 5, and the belt conveyor structure III-a is docked with the belt conveyor structure II and the fragment unloading box 4, and then the battery cells are transported from the belt conveyor structure III-b to the belt conveyor structure IV-b in the feeding conveyor line 5, and the belt conveyor structure III-a is responsible for continuing to receive the battery cells transmitted from the belt conveyor structure II. According to the above logic, the two belt conveyor structures III can work crosswise.

[0055] In the feeding conveyor line 5: the servo motor III 32 drives the active roller 34 to rotate through the synchronous belt III, and then drives the belt II 33 to move, so as to realize the conveying of the battery cell. When the output end of the belt conveying structure IV is plugged into the input end side of the loading platform 42, the industrial camera II 35 can take the image of the battery cell to further determine whether the battery cell is centered on the loading platform 42; if the battery cell is not centered, the battery cell can be corrected by the correction execution component (the working principle of the correction execution component is similar to that of the correction structure I, which will not be repeated here); when the battery cell is corrected and centered on the loading platform 42, the loading platform 42 is separated from the belt conveying structure IV, and the battery cell moves with the loading platform 42 to the bottom of the laser enhancement platform 6 to receive laser enhancement processing.

[0056] In the cross-carrying platform 7: the linear motor module II 39 works, which can drive the carrier 42 to translate, so as to achieve the docking of the carrier 42 with the loading conveyor line 5, the unloading conveyor line 8 and the laser enhancement platform 6. When the carrier 42 reaches the horizontal processing position below the laser enhancement platform 6, the servo motor V 40 works to rotate the screw of the ball screw 41 and make the nut seat move linearly, and the connecting plate will move up and down accordingly, thereby driving the carrier 42 to move up and down, so that the carrier 42 reaches the height working position. In this embodiment, since the carrier platform 42 is a double-sided composite structure, a double-station cross-working mode can be implemented. Specifically, both the carrier platform a-Ⅰ and the carrier platform a-Ⅱ can carry battery cells independently; at a certain time point, after the battery cells on the carrier platform a-Ⅰ have been subjected to laser scanning, the carrier platform a-Ⅰ needs to be moved to dock with the unloading conveyor line 8 under the action of the linear motor module Ⅱ39 and the platform lifting mechanism to realize the transfer of the scanned battery cells; at the same time, the carrier platform a-Ⅱ can carry new battery cells that have not yet been scanned, and under the action of the linear motor module Ⅱ39 and the platform lifting mechanism, it moves to the processing position below the laser enhancement platform 6, so that the new battery cells can be powered by the probe and scanned by the laser. When the carrier a-Ⅰ completes the transfer operation, it can be moved to the same horizontal position opposite to the carrier a-Ⅱ under the action of the linear motor module Ⅱ39 and the platform lifting mechanism to wait (during the waiting period, a new battery cell is placed on the carrier a-Ⅰ), but the height of the carrier a-Ⅰ is lower than the height of the carrier a-Ⅱ; when the battery cell on the carrier a-Ⅱ is completely scanned by the laser, the carrier a-Ⅱ transfers the battery cell; at the same time, the carrier a-Ⅰ rises to the processing position, so that the new battery cell on the carrier a-Ⅰ can be powered by the probe and scanned by the laser. Then, the two carriers 42 work crosswise according to the above process.

[0057] In the laser enhancement platform 6: the laser 44 can emit laser toward the battery cell on the carrier platform 42, and the probe array 45 can contact the battery cell on the carrier platform 42 to conduct electricity, thereby realizing laser enhancement processing of the battery cell. In this embodiment, since a laser 44 and a power-on mechanism are respectively installed on both sides of the bracket 43, double-line operation can be performed.

[0058] The unloading conveyor line 8 is used to receive and convey the battery cells after scanning. The working principle of the unloading conveyor line 8 itself and the docking principle between it and the cross-carrying platform 7 can be referred to the part of the loading conveyor line 5, which will not be repeated here.

[0059] The translational unloading mechanism 9 is used to receive and convey the battery cells conveyed from the unloading conveyor line 8, and it can realize the cross-operation of the two belt conveyor structures V. Specifically: when the battery cells flow out from the belt conveyor structure V-a located on the left side of the unloading conveyor line 8, the linear motor module III46 will operate to make the belt conveyor structure VI-a and the belt conveyor structure VI-b move left synchronously, based on this, the belt conveyor structure VI-a is connected with the belt conveyor structure V-a, and the belt conveyor structure VI-b is located in the middle position of the linear motor module III46, and then the battery cells are conveyed from the belt conveyor structure V-a to the belt conveyor structure VI-a in the translational unloading mechanism 9. When the battery cells flow out from the belt conveyor structure V-b located on the right side of the unloading conveyor line 8, the linear motor module III46 will operate to make the belt conveyor structure VI-a and the belt conveyor structure VI-b move right synchronously, based on which the belt conveyor structure VI-b is docked with the belt conveyor structure V-b, the belt conveyor structure VI-a is located in the middle position of the linear motor module III46 and docked with the unloading and correcting mechanism 10, and then the battery cells are transported from the belt conveyor structure V-b to the belt conveyor structure VI-b in the translation unloading mechanism 9, and the battery cells on the belt conveyor structure VI-a are transported to the unloading and correcting mechanism 10. According to the above logic, the two belt conveyor structures V can work crosswise.

[0060] The unloading and correcting mechanism 10 is used to realize the correction of the battery cell. Its working principle can refer to the working principle of the correction structure I. Specifically: the servo motor VI50 drives the synchronous wheel IV51 to rotate, and the synchronous wheel IV51 drives the synchronous belt V52 to move, which can then drive the two correction clamps III53 on both sides of the belt conveyor structure VII to cyclically contract inward and open outward, thereby correcting the battery cell; among them, when the induction sensor 56 senses the approach of the induction sheet 55, it will send a signal to the servo motor VI50 to change the direction of movement of the synchronous belt V52.

[0061] The discharging mechanism 11 is used to realize the output of the battery cells. Its working principle can refer to the working principle of the belt conveyor structure I, which will not be repeated here.

[0062] In summary, the laser efficiency-enhancing processing streamline provided in this embodiment can not only perform automated, batch, and flow-type laser efficiency-enhancing processing on battery cells, but also realize dual-line loading, unloading, and laser irradiation operations, thereby effectively improving processing efficiency.
