DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figure 1-2As shown, a laser induced sintering device for solar panels in an embodiment of the present invention comprises a device body 1, a conveying system 2 is installed in the device body 1, an air suspension positioning system 3 is installed on the inner wall of one end of the conveying system 2, a laser control system 4 is installed above the conveying system 2 in the device body 1, a heat transmission system 5 is fixedly connected above the laser control system 4, a detection transfer system 6 is installed in the middle of the conveying system 2 in the device body 1, a plc controller 7 is installed on the upper end surface of the device body 1, the device body 1 comprises a sintering conveying bin 101 and a defective product transfer bin 102, the defective product transfer bin 102 is integrally formed on one side wall of the sintering conveying bin 101, and the conveying system 2 comprises a first conveying platform 201, a second conveying platform 202, and a heat transfer system 5 is fixedly connected above the laser control system 4. 2 and the third conveyor platform 203, the first conveyor platform 201 and the second conveyor platform 202 are installed on the inner wall of the sintering conveying bin 101, and the third conveyor platform 203 is installed on the inner wall of the defective product transfer bin 102. The inner walls of the sintering conveying bin 101 and the defective product transfer bin 102 are connected. The solar panel is transported from the previous process to the side of the conveying system 2 close to the air suspension positioning system 3 and enters the equipment body 1, and then passes through the laser control system 4 and the heat transmission system 5 above the conveying system 2, and is finally transported to the second conveyor platform 202 and the third conveyor platform 203 after inspection, and then transported to the exits on both sides of the sintering conveying bin 101 and the defective product transfer bin 102 through the second conveyor platform 202 and the third conveyor platform 203.

[0031] like Figure 3 As shown, a first motor 2011 is installed on one side wall of the first conveying platform 201, and protective plates 2012 are fixedly connected at both ends of the first conveying platform 201. A first bevel gear 2021 is installed on one side wall of the second conveying platform 202, and rotating shafts are provided at both ends of the second conveying platform 202. The first bevel gear 2021 is fixedly connected to the rotating shaft in the second conveying platform 202. A second motor 3032 is installed on one side wall of the third conveying platform 203, and the output end of the second motor 3032 is fixedly connected to the third gas mold conveying device 3031. Both ends of the third conveying platform 203 are provided with There is a rotating shaft, the second bevel gear 2031 is fixedly connected to the rotating shaft in the third conveyor platform 203, the first bevel gear 2021 and the second bevel gear 2031 are meshed with each other, the first conveyor platform 201 is driven to work by the first motor 2011, and the third conveyor platform 203 is driven to work by the second motor 3032, and at the same time, the second bevel gear 2031 and the first bevel gear 2021 are meshed, thereby driving the second conveyor platform 202 to work, so that the second motor 3032 drives the second conveyor platform 202 and the third conveyor platform 203 to work at the same time, which greatly saves energy consumption.

[0032] like Figure 4As shown, the air suspension positioning system 3 includes a bottom air mold generating device 301, which is installed on the inner wall of the protective plate 2012 on the first conveying platform 201, and a first air mold hole 3011 is opened on the bottom air mold generating device 301. A pair of inner walls of the protective plate 2012 are both installed with parallel air mold generating devices 302, and a side wall of the parallel air mold generating device 302 is provided with a second air mold hole 3021. An inclined air mold conveying device 303 is installed on a pair of side walls of the protective plate 2012 close to the bottom air mold generating device 301, and a third air mold conveying device 3031 is opened on one side wall of the inclined air mold conveying device 303. The pair of inclined air mold conveying devices 303 are inclined. When the solar cell panel reaches above the bottom air mold generating device 301, the air suspension positioning system 3 works, and the stable air generated by the bottom air mold generating device 301 The source is ejected from the first air mold hole 3011, so that the first air mold hole 3011 forms a uniform air mold under the battery panel, so that the battery panel that has just entered the equipment body 1 can be suspended, to avoid damage to the battery panel when the battery panel is in direct contact with the first conveying platform 201. Then, when it reaches the inner side of a pair of inclined air mold conveying devices 303, the third air mold conveying device 3031 forms a stable air mold on both sides of the battery panel, driving the battery panel to slowly adjust the position of the left and right sides. Then, when the battery panel reaches the inner side of a pair of parallel air mold generating devices 302, the second air mold hole 3021 forms a stable air mold on both sides of the battery panel, and once again accurately adjusts the precise positioning of the battery panel above the first conveying platform 201 to ensure that the laser beam can accurately irradiate the predetermined position. If the equipment accuracy is insufficient or the positioning is inaccurate, the sintering position may be offset, affecting the connection quality and performance of the battery panel.

[0033] Furthermore, the dust on the surface of the inflatable solar panel produced by the bottom inflatable mold generating device 301, the parallel inflatable mold generating device 302 and the inclined inflatable mold conveying device 303 has a certain cleaning effect, causing some dust particles to fall off from the surface of the solar panel, thereby reducing dust adhesion, thereby greatly improving the quality of the solar panel after sintering.

[0034] like Figure 5As shown, the heat transfer system 5 includes a supporting shell 501, an exhaust pipe 502 is installed on the inner wall of the supporting shell 501, and a plurality of exhaust holes 5021 are opened on the outer wall of the exhaust pipe 502. One end of the exhaust pipe 502 passes through the supporting shell 501 and is connected with a first air pump connecting pipe 503. A double-headed air pump 504 is installed on the top end surface of the sintering conveying bin 101. One end of the double-headed air pump 504 is fixedly connected to the first air pump connecting pipe 503, and the other end is fixedly connected to the second air pump connecting pipe 503. Tube 505, a heat collecting bin 506 is installed on the top end surface of the sintering conveying bin 101, a connecting hole matching the second air pump connecting pipe 505 is opened on one side wall of the heat collecting bin 506, one end of the second air pump connecting pipe 505 is fixedly connected to the heat collecting bin 506 on one side of the mounting hole, a plurality of groups of air outlet holes 5061 are opened below the heat collecting bin 506, and the heat collecting bin 506 is located directly above the side of the first conveying platform 201 close to the air suspension positioning system 3. The laser control system 4 will generate high temperature after long-term operation. When high temperature is generated, the double-head air pump 504 is turned on, and one end of the double-head air pump 504 is connected to the first air pump connecting pipe 503 and the exhaust pipe 502. A plurality of exhaust holes 5021 are provided on the exhaust pipe 502. The exhaust holes 5021 are distributed on both sides of the laser control system 4, so that one end of the double-head air pump 504 drives the gap with heat around the laser control system 4 to be sucked into the exhaust pipe 502, thereby accelerating the flow of air around the laser control system 4, playing a certain cooling effect on the laser control system 4, and avoiding the performance of the sintered battery panel affected by excessive temperature.

[0035] Furthermore, a smoke filter is installed on the inner wall of the air outlet 5061 in the heat collection bin 506. During the laser sintering process, smoke may be generated. When the double-head air pump 504 is working, it drives the exhaust pipe 502 to inhale air. These harmful substances are sucked into the heat collection bin 506 in time, and the clean gas after passing through the smoke filter is ejected from the air outlet 5061, thereby reducing the pollution of air quality.

[0036] Furthermore, a large amount of heat in the exhaust hole 5021 is transferred to the heat collection bin 506 through the second air pump connecting pipe 505 under the action of the double-head air pump 504, and then ejected from the air outlet 5061. The air outlet 5061 is located above the first conveying platform 201 in the equipment body 1 where the battery panel has just entered, so that the heat ejected from the air outlet 5061 preheats the battery panel before sintering, thereby reducing the temperature difference of the battery panel before and after sintering, improving the quality of the battery panel after sintering, and realizing energy recovery and utilization, which greatly reduces energy loss.

[0037] like Figure 1-2 and Figure 6As shown, the detection transfer system 6 includes a support column 601, a rotation system 602 is installed on the outer wall of the support column 601, a first opening groove is provided on one side wall of the rotation system 602, an electric telescopic rod 604 is installed on the inner wall of the opening groove, a mechanical arm 603 matching the first opening groove is installed above the electric telescopic rod 604, a first slider is integrally formed on a pair of side walls of the mechanical arm 603, a first slide groove matching the first slider is provided on the inner wall of the opening groove, the first slider slides on a pair of groove walls of the first slide groove, one end side wall of the mechanical arm 603 slides on the inner wall of the opening groove, an electromagnetic adsorption system 605 is installed on the bottom end face of the mechanical arm 603, the support column 601 is installed in the sintering conveying bin 101 and is located between the first conveying platform 201 and the second conveying platform 202, the third conveying platform 203 is located on one side of the support column 601, and the support column 60 1 is installed with a motor, a pair of gears are fixedly connected to the output end of the motor, a bearing is installed in the rotating system 602, and a plc controller 7 is installed above the equipment body 1. The corresponding program is input into the plc controller 7 to realize the detection and transfer system 6 to accurately control the adsorption, detection, rotation and conveying processes for automatic control: when the battery panel is transported to the side of the first conveying platform 201 close to the detection and transfer system 6, the plc controller 7 controls the motor located in the support column 601 to work, thereby driving the gear to rotate, driving the mechanical arm 603 to rotate to the first conveying platform 201 above the battery panel, and then the plc controller 7 controls the electric telescopic rod 604 to drive the mechanical arm 603 to move downward, and then the electromagnetic adsorption system 605 works. A number of adsorption holes are opened on the electromagnetic adsorption system 605 to achieve stable adsorption of the battery panel, ensuring the stability of subsequent conveying work.

[0038] Furthermore, a UMC detection device is installed inside the mechanical arm 603, and a characteristic monitoring point is set on the battery panel. When the battery panel is adsorbed by the electromagnetic adsorption system 605, the UMC detection device located inside the mechanical arm 603 just contacts the inspection point on the battery panel, thereby realizing the detection of the battery panel after sintering. Through the UMC detection, possible problems in the sintering process, such as incomplete sintering, over-sintering, etc., can be discovered in time, thereby ensuring the quality of the battery panel; the UMC detection can comprehensively evaluate the performance of the battery panel, including key parameters such as open circuit voltage, short circuit current, fill factor, and conversion efficiency. These parameters can reflect the photoelectric conversion capacity and stability of the battery panel, and are of great significance to the application and performance optimization of the battery panel; through the UMC detection, potential defects in the battery panel, such as cracks, open circuits, short circuits, etc., can be discovered in time. These defects may cause the performance of the battery panel to deteriorate or fail during use, so timely discovery and repair of these defects can improve the reliability of the battery panel; by analyzing the detection results, the influence of the sintering process on the performance of the battery panel can be understood, thereby adjusting the sintering temperature, time and other parameters, optimizing the production process, and improving the performance and stability of the battery panel.

[0039] Furthermore, the corresponding program is input into the PLC controller 7 to control the qualified and abnormal conditions of the battery panels after the detection is completed, so as to realize the real-time detection of the battery panels. Once a problematic battery panel is detected, the system can immediately trigger the corresponding mechanism to separate it from the transmission line and transport it separately, adjust the position of the battery panel transportation, and rotate the sintered battery panel by 90 degrees and 108 degrees respectively according to the qualified and abnormal conditions and transport it to the top of the second conveyor platform 202 and the third conveyor platform 203, and then transport it to the next process, thereby reducing the workload in the later stage and enhancing the flexibility of production.

[0040] When in use, the solar panel is transported into the equipment body 1 by the previous process, and first arrives at the side of the first conveying platform 201 close to the air suspension positioning system 3. When passing through the air suspension positioning system 3, the skewed or offset solar panel is automatically corrected, and then passes under the heat transfer system 5, so that the heat generated by the laser control system 4 is transferred to the top of the solar panel through the heat transfer system 5, and the solar panel is preheated before sintering. Then the solar panel arrives under the laser control system 4, so that the laser control system 4 sinters the solar panel, and the solar panel after sintering arrives on the first conveying platform 201 Close to one end of the detection and transfer system 6, the detection and transfer system 6 then absorbs the solar panel for detection. At this time, the solar panel is separated from the first conveyor platform 201. Then, according to the detection results and the qualified and abnormal data formulated by the staff, the detection and transfer system 6 rotates the abnormal solar panel 90 degrees and transfers it to the top of the third conveyor platform 203, and then transports it to the next process through the third conveyor platform 203, and rotates the qualified solar panel 180 degrees and transfers it to the top of the second conveyor platform 202, and then transports it to the next process through the second conveyor platform 202, thereby completing the laser sintering of the solar panel.
