Description

Technical Field

[0001] The invention belongs to the technical field of solar cell preparation equipment, and in particular relates to an additive adding device for texturing a large solar cell panel. Background Art

[0002] Solar panels play a vital role in photovoltaic power generation systems, and their performance directly affects the power generation efficiency of photovoltaic power generation systems. The texturing process of large-sized solar panels is one of the key steps to improve the photoelectric conversion efficiency of solar panels. Through the texturing process, the light absorption area can be increased and the reflection loss can be reduced. In the texturing process, the application of additives is crucial to improving the texturing effect.

[0003] In the texturing process, the application of additives is crucial to the texturing effect.

It is difficult to adjust the metering and proportioning of additives according to the state of the forming tower base on the solar cell panel only by manual or semi-automatic means, so it is difficult to ensure that the texturing quality reaches the expected goal, affecting the overall texturing effect and the final conversion efficiency of the solar cell panel.

[0027] 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.

[0028] like Figure 1 to Figure 6 As shown, an additive adding device for texturing a large solar cell panel in one embodiment of the present invention is used to add additives into a texturing device 1. The texturing device 1 has a plurality of texturing slots 2, which are evenly distributed inside the texturing device 1. A mechanical arm is provided inside the texturing device 1, and the mechanical arm can grab a large solar cell panel, grab the large solar cell panel from one texturing slot 2 to another texturing slot 2, and the large solar cell panel contacts additives of different components, forming a pyramid-structured velvet surface on the surface.

[0029] In order to prevent the additives attached to the solar panels from mixing with the additives in other texturing tanks 2 and affecting the mixing quality of the additives during the process of the robot arm moving the solar panels, a adding device is provided, which can deliver mixed additives to the texturing tank 2, or deliver one additive to different texturing tanks 2 separately, thereby changing the mass ratio of the mixed additives in the texturing tank 2, so that the mixed additives in the texturing tank 2 are always in a state that is conducive to texturing.

[0030] like Figure 1 to Figure 6As shown, the adding device includes a first liquid replenishing mechanism and a second liquid replenishing mechanism, the first liquid replenishing mechanism is used to deliver mixed additives into the texturing tank 2, and the second liquid replenishing mechanism is used to deliver one or more additives into the texturing tank 2. That is, when the content of additives in the texturing tank 2 is too little as a whole, the first liquid replenishing mechanism can be used to replenish the texturing tank 2. The second liquid replenishing mechanism needs to add corresponding additives into the texturing tank 2 according to the mass ratio of the additives in the texturing tank 2.

[0031] like Figure 1 to Figure 6 As shown, the first liquid replenishing mechanism includes a mixing mechanism 3 and a diverter 8. The diverter 8 is used to concentrate multiple additives and distribute the concentrated additives, and can also concentrate one additive and distribute the additive to the texturing tank 2. A first liquid outlet pipe 11 is installed between the mixing mechanism 3 and the diverter 8. The additives in the diverter 8 can enter the mixing mechanism 3 and be mixed by the mixing mechanism 3. After being evenly mixed, they can be transported to the texturing tank 2 for use.

[0032] Specifically, Figure 5 As shown, the mixing mechanism 3 includes a liquid storage tank 4, a sealing cover 5 is fixedly connected to the liquid storage tank 4 by bolts, a motor 6 is fixedly connected to the upper end of the sealing cover 5, a stirring rod 7 is rotatably connected inside the liquid storage tank 4, and one end of the stirring rod 7 close to the motor 6 penetrates the sealing cover 5 and is fixedly connected to the output shaft of the motor 6. That is, the motor 6 can drive the stirring rod 7 to rotate in the liquid storage tank 4 to achieve stirring and uniform mixing of the additives.

[0033] Among them, the fourth liquid outlet pipe 16 is installed on the liquid storage tank 4, and a plurality of fifth liquid outlet pipes 1601 matching the texturing tank 2 are fixedly connected to the fourth liquid outlet pipe 16. That is, the end of the fifth liquid outlet pipe 1601 away from the fourth liquid outlet pipe 16 is connected to the texturing tank 2. The mixed additive passes through the liquid storage tank 4, the fourth liquid outlet pipe 16 and the fifth liquid outlet pipe 1601 in sequence, and finally enters the texturing tank 2 to achieve the addition of the mixed additive.

[0034] like Figure 6 As shown, the flow divider 8 includes a manifold 9, and a plurality of connecting nozzles 10 are fixedly connected to the manifold 9, and the connecting nozzles 10 are used to connect to a liquid infusion tube 13 for conveying different additives. The liquid infusion tube 13 conveys the additives to the manifold 9, and the various additives in the manifold 9 can be preliminarily mixed by the impact force generated by the conveying, and then conveyed to the mixing mechanism 3 through the first liquid outlet pipe 11 for further mixing.

[0035] like Figure 1 to Figure 6As shown, the second liquid replenishing mechanism includes a second liquid outlet pipe 12, which is installed at one end of the collecting pipe 9, and the end of the second liquid outlet pipe 12 away from the collecting pipe 9 is fixedly connected with the second liquid outlet pipe 12, and the end of the second liquid outlet pipe 12 away from the collecting pipe 9 is fixedly connected to the sixth liquid outlet pipe 14, and the sixth liquid outlet pipe 14 is installed with a plurality of third liquid outlet pipes 15 matching the texturing tank 2. One or more additives enter the collecting pipe 9 from the infusion pipe 13 in turn, and are then transported to the second liquid outlet pipe 12, the sixth liquid outlet pipe 14 and the third liquid outlet pipe 15 in turn by the collecting pipe 9. The third liquid outlet pipe 15 transports the additives to the texturing tank 2 to achieve the increase of one or more additives. By accurately detecting the content of the mixed additives and adding the additives through the second liquid replenishing device, the additives in the texturing tank 2 are always in a state conducive to texturing.

[0036] In order to accurately detect the state of the additive in the texturing tank 2, the adding device includes an additive detection system, which is used to detect the mass ratio of the additive in the texturing tank 2, and can cooperate with the second liquid replenishing mechanism to add additives to the texturing tank 2. Even if the additives in one texturing tank 2 are mixed with the additives in another texturing tank 2, the second liquid replenishing mechanism can add repair additives according to the detection results of the additive detection system, and the mixed additives are restored to a state capable of texturing the large solar panels.

[0037] Specifically, Figure 1 to Figure 4 As shown, the additive detection system includes an infusion system and a detection device. The infusion system is located in the texturing tank 2, and is used to collect the additives in the texturing tank 2 at multiple points and transport them to the detection device for detection. The detection device includes a chromatograph 21 and a spectrometer 23, and the infusion system includes a chromatograph delivery system 22 and a spectrometer delivery system 24. The chromatograph delivery system 22 and the spectrometer delivery system 24 are both located in the texturing tank 2, and the chromatograph 21 and the spectrometer 23 are interconnected, and the chromatograph delivery system 22 and the spectrometer delivery system 24 are interconnected.

[0038] In order to reduce the measurement error, the additive sample collected by the chromatograph delivery system 22 and the spectrometer delivery system 24 is the same sample. The infusion system divides the unified sample into two parts and provides them to the chromatograph 21 and the spectrometer 23 respectively. The chromatograph 21 and the spectrometer 23 respectively detect the test results. The test results are tested multiple times, and the average value of the test results is taken. Additives are added to the texturing tank 2 according to the average value, which can largely avoid the situation where too much or too little additive is added due to the detection error.

[0039] In order to adjust the dosage and ratio of the additive according to the state of the forming tower base on the large solar cell panel, the adding device also includes a velvet surface detection mechanism 17, which can detect the velvet surface on the large solar cell panel, and the second liquid replenishing mechanism replenishes the liquid according to the velvet surface detection result.

[0040] When the equipment starts to run, the suede inspection results are generally observed manually, and the second liquid replenishment mechanism is used according to the suede inspection results. In order to achieve more intelligent liquid replenishment, the device also includes an intelligent analysis system, which can conduct in-depth learning of suede quality and the process of adding additives, and can train the intelligent analysis system through a large amount of data to achieve intelligent liquid replenishment.

[0041] like Figure 1 to Figure 4 As shown, the textured surface detection mechanism 17 includes a plurality of ultrasonic detection devices 18, which are evenly distributed inside the textured tank 2, and can perform real-time detection on the textured process of the solar cell and judge the textured quality. In particular, three data comparisons can be performed before, during and after the textured process, and the quality of the textured process can be judged based on the data comparison results.

[0042] In addition, in order to improve the accuracy of the detection results of the textured surface detection mechanism 17, the textured surface detection mechanism 17 also includes a radar detection device 19 and a visual detection device 20. The radar detection device 19 and the visual detection device 20 are both installed at the upper end of the textured tank 2. The radar detection device 19 detects the textured quality of the silicon wafer by radar, and the visual detection device 20 detects the textured quality by visual means. The detection results of the ultrasonic detection device 18, the radar detection device 19 and the visual detection device 20 can be compared. Multiple detection mechanisms are compared and the average value of the results is taken, which can largely avoid the situation where a single detection structure affects the detection accuracy.

[0043] The detection result of the velvet surface detection mechanism 17 can be matched with the additive in the velvet tank 2. For example, when the velvet quality is 1, the additive mass ratio detected by the additive detection system is 1, but the velvet quality detected by the ultrasonic detection device 18 is 1.2, the velvet quality detected by the radar detection device 19 is 0.9, and the velvet detection quality of the visual detection device 20 is 1.1. The average value of the velvet surface quality detection result is 1. If the results of multiple detection data are also the same, then the relationship between the detection results of the ultrasonic detection device 18, the radar detection device 19 and the visual detection device 20 and the additive detection system can be determined. Using this relationship, this result can be used on other production lines. For example, another production line only uses the radar detection device 19 to detect the velvet quality, and the detection result is 0.9. It can be judged that there is no problem with the velvet quality, and the mass ratio of the components in the additive is also correct, and no additional additives are needed. This method can reduce the detection error caused by relying on only one detection device without adding additional equipment, and can analyze the error relationship between the velvet surface detection system and the additive detection system, greatly improving the accuracy of velvet quality detection.

[0044] The velvet surface detection mechanism 17 and the additive detection system can be used together. When in use, it is necessary to manually import data. The velvet surface detection mechanism 17 can detect the quality of velvet and judge the quality of the velvet surface. If you want to further improve the velvet effect, use the additive detection system to detect the additive ratio of the data that matches the imported data, and add the corresponding additives through the second liquid replenishment mechanism. That is, the proportion of the additives can be judged by the velvet surface detection mechanism 17, and the quality of the velvet surface can also be judged by the additive detection system. The combination of the two is more conducive to judging the quality of velvet, and the judgment effect is more accurate and less prone to deviation.

[0045] The intelligent analysis system can analyze the relationship between the suede and the additives, and can obtain analysis data, can upload the analysis data, and the analysis data is used for adding the device.

[0046] When in use, the solar cell is first transported to the texturing device 1, and the large solar cell is transported by the robot arm to the first texturing tank 2. During the texturing of the large solar cell in the texturing tank 2, the additive detection system and the texturing surface detection system are detected at the same time. The detection results of the two are compared, and the second liquid replenishing mechanism replenishes the corresponding additive into the texturing tank 2 according to the detection results.

[0047] If the additive content in the texturing tank 2 is reduced as a whole, the first liquid replenishing mechanism is used to add additives mixed in a certain ratio into the texturing tank 2. Among them, the mixing mechanism 3 can store a certain amount of additives, which can be used and released when in use, which is conducive to improving the liquid replenishing efficiency of the first liquid replenishing mechanism.

[0048] The present invention sets up a velvet surface detection system and an additive detection system. The proportional relationship between the velvet surface and the additive can be analyzed by the intelligent analysis system. According to the detection mechanisms in the velvet surface detection system and the additive detection system, the error degree between the detection mechanisms can be analyzed. The velvet surface detection system and the additive detection system can be used in another production line. By adjusting the parameters in the other production line, the situation in which the detection error affects the velvet quality can be reduced. There is no need to upgrade the equipment in the production line, which is beneficial to saving the upgrade cost of the production line.
