Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel spraying, and particularly to a multi-mode switching adaptive photovoltaic panel spraying device. Background Art

[0002] In the field of photovoltaic panel manufacturing, coating spraying technology is a key link to improve the photoelectric conversion efficiency, environmental durability and surface functionality of photovoltaic modules. There are various types of coatings for photovoltaic panels, including anti-reflection coatings, hydrophobic and anti-fouling coatings, anti-PID coatings, and protective coatings for enhancing mechanical strength. These coatings need to be customized according to the material of the photovoltaic panel, the use environment and functional requirements.

[0003] The patent with the publication number CN117563854A discloses a spraying device and spraying method for processing non-PID-decaying TOPcon photovoltaic modules, including a vacuum chuck. A moving device for driving its movement is installed at the bottom of the vacuum chuck, and the vacuum chuck is used for the adsorption and positioning of the photovoltaic panel. It also includes two mounting brackets installed at both ends of the vacuum chuck. A moving unit is installed in the two mounting brackets, and a moving seat is docked on the moving unit. A spraying head is installed at the bottom of the moving seat. Mounting plates are installed on both sides of the moving seat, and a blowing unit is installed on the mounting plates. The blowing unit is used for removing dust particles on the photovoltaic panel, and a driving mechanism for driving the two blowing units is also installed on the mounting plates.

[0004] In the above patent, the moving unit drives the moving seat to reciprocate on the photovoltaic panel, and the moving seat drives the spraying head to reciprocate on the photovoltaic panel for spraying the photovoltaic panel. There is only one spraying head. However, the chemical compositions of different coating liquids are significantly different. For example, a certain anti-PID coating may contain an alkaline buffer, and a hydrophobic coating may contain an acidic catalyst. If not thoroughly cleaned when changing the coating liquid, the two coating liquids may undergo a chemical reaction in a closed space, resulting in cross-contamination, which may cause impurities or reaction by-products to be mixed into the new coating liquid, reducing the uniformity and adhesion of the coating liquid. Frequent replacement of the spraying head will significantly increase labor and consumable costs, and at the same time extend the equipment downtime. Summary of the Invention

[0005] In view of this, the present invention provides a multi-mode switching adaptive photovoltaic panel spraying device, which can overcome the drawback that two coating liquids may undergo a chemical reaction in a closed space, resulting in cross-contamination, which may cause impurities or reaction by-products to be mixed into the new coating liquid, reducing the uniformity and adhesion of the coating liquid.

Specific Embodiments

[0030] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0031] Reference Figures 1-6 Figures 1-6 , a multi-mode switching adaptive photovoltaic panel spraying device, comprising a frame 1, a conveyor 2, a bracket 3, a robotic arm 4, a mounting block 5, a mounting box 6, a mounting ring 7, a rotating box 8, a mounting pipe 9, a nozzle 10, a liquid storage tank 11, a suction pump 12, a rigid pipe 13, a flexible pipe 14, a rotating mechanism and a sealing mechanism. The conveyor 2 is bolted to the top of the frame 1. On the front and back sides of the right side of the top of the frame 1, brackets 3 are bolted. On one side of the two brackets 3 close to each other, robotic arms 4 are bolted. On the execution ends of the robotic arms 4, mounting blocks 5 are connected. At the bottom of the mounting blocks 5, mounting boxes 6 are bolted. On the front and back sides inside the mounting boxes 6, mounting rings 7 are connected. Inside the same mounting box 6, two mounting rings 7 jointly rotatably connect a rotating box 8. On the rotating box 8, three mounting pipes 9 are evenly spaced and connected. On the mounting pipes 9, nozzles 10 are connected. The types of the three nozzles 10 on the same rotating box 8 are different. On the left and right sides of the bottom of the mounting box 6, there are inlets and outlets. The nozzles 10 enter the mounting box 6 through these inlets and outlets. On one side of the two brackets 3 away from each other, three liquid storage tanks 11 are bolted. On the liquid storage tanks 11, suction pumps 12 are bolted. The liquid inlet ends of the suction pumps 12 extend into the liquid storage tanks 11. On the liquid outlet ends of the suction pumps 12, rigid pipes 13 are connected. The rigid pipes 13 are connected to the brackets 3. On the rigid pipes 13, flexible pipes 14 are connected. The flexible pipes 14 are connected to the mounting pipes 9. The rotating mechanism is used to control the rotation of the nozzles 10 and switch the nozzles 10. The sealing mechanism is used to seal the inlets and outlets on the mounting box 6.

[0032] Reference Figure 5 Figure 5 , the rotating mechanism includes a full gear 151, a stepper motor 152 and a sector gear 153. On one side of the two rotating boxes 8 away from each other, full gears 151 are installed. On the mounting blocks 5, stepper motors 152 are bolted. On the output shafts of the stepper motors 152, sector gears 153 are key-connected. The number of teeth of the full gear 151 is four times that of the sector gear 153. During the rotation of the sector gear 153, it will mesh with the full gear 151.

[0033] Reference Figure 6 Figure 6 , the sealing mechanism includes a rotating shaft 161 and a sealing block 162. On the left and right sides of the bottom of the mounting box 6, rotating shafts 161 are rotatably connected. At the front and rear of the rotating shafts 161, torsion springs are sleeved. The two ends of the torsion springs are respectively connected to the mounting box 6 and the rotating shafts 161. On the rotating shafts 161, sealing blocks 162 are connected.

[0034] The staff pour three different coating liquids into three liquid storage tanks 11 respectively. The left side of the conveyor 2 is docked with the production line, and the photovoltaic panels are sent to the conveyor 2 through the production line. The conveyor 2 conveys the photovoltaic panels to the right and transports the photovoltaic panels below the nozzle 10. The suction pump 12 sucks the coating liquid in the liquid storage tank 11 into the hard pipe 13. The coating liquid sprays out from the nozzle 10 through the hose 14 and the installation pipe 9 and sprays onto the photovoltaic panel. The robotic arm 4 can control the movement of the nozzle 10 to adapt to different photovoltaic panels such as curved photovoltaic panels and flat photovoltaic panels. When spraying different photovoltaic panels, the types of the coating liquid and the nozzle 10 also need to be replaced accordingly. Controlling the output shaft of the stepping motor 152 to rotate one circle drives the sector gear 153 to rotate one circle. During the rotation of the sector gear 153, it meshes with the full gear 151 and drives the full gear 151 to rotate. The full gear 151 drives the rotating box 8 to rotate, and the rotating box 8 drives the nozzle 10 to rotate. When the nozzle 10 contacts the sealing block 162, it will push the sealing block 162, causing the sealing block 162 to rotate, and the torsion spring deforms. The nozzle 10 that is not needed rotates into the installation box 6, and the nozzle 10 that needs to be used rotates out of the installation box 6 to switch the nozzle 10. When the nozzle 10 and the sealing block 162 are disengaged, under the action of the torsion spring, the sealing block 162 rotates reversely to reset and seals the inlet and outlet on the installation box 6 again, preventing dust or coating liquid from floating into the installation box 6 and contaminating the nozzle 10. When the sector gear 153 and the full gear 151 are not meshed, the full gear 151 stops rotating, and the nozzle 10 also stops rotating. The number of teeth of the full gear 151 is four times that of the sector gear 153. Therefore, when the sector gear 153 rotates one circle, the full gear 151 rotates one-fourth of a circle to complete the switching of the nozzle 10. Different spraying modes can be selected according to different photovoltaic panels, avoiding sharing the same nozzle 10 and preventing chemical reactions between the two coating liquids from causing cross-contamination, ensuring the uniformity and adhesion of the coating liquid. When the photovoltaic panel does not need to be sprayed, all the nozzles 10 can be rotated into the installation box 6 to protect the nozzles 10 through the installation box 6 and prevent dust from contaminating the nozzles 10.

[0035] Refer to Figures 7-9, also includes a cleaning mechanism. The cleaning mechanism includes a water inlet pipe 171, a first solenoid valve 172, a second solenoid valve 173, a guide frame 174, a water outlet pipe 175, a first spring 176, a third solenoid valve 177, a sealing ring 1712 and a control component. The water inlet pipes 171 are connected to the hard pipes 13, the first solenoid valves 172 are installed on the water inlet pipes 171, the second solenoid valve 173 is installed on the hard pipe 13 near the suction pump 12, the guide frames 174 are connected to the right side of the installation box 6, the water outlet pipes 175 are slidably connected to the guide frames 174, the water outlet pipes 175 slidably penetrate through the right side of the installation box 6, the first springs 176 are sleeved on the front and rear parts of the guide frames 174, the two ends of the first springs 176 are respectively connected to the guide frames 174 and the water outlet pipes 175, and the first springs 176 are sleeved on the guide frames 174 to prevent the first springs 176 from bending. The third solenoid valves 177 are installed on the upper parts of the water outlet pipes 175, the sealing rings 1712 are connected to the lower parts of the water outlet pipes 175, and the control component is used to control the docking and separation of the water outlet pipes 175 and the installation pipes 9.

[0036] Refer to Figure 7 and Figure 8 , the control component includes a guide block 178, a slide bar 179, a cam 1710 and a limit block 1711. The guide blocks 178 are connected to the right side of the top of the installation box 6, the slide bars 179 are slidably connected to the guide blocks 178, the right ends of the slide bars 179 are connected to the left sides of the water outlet pipes 175, the cams 1710 are key-connected to the output shafts of the stepper motors 152, and the limit blocks 1711 are connected to the right sides of the cams 1710.

[0037] When it is necessary to spray the photovoltaic panel, the solenoid valve II 173 can be controlled to open, and the solenoid valve I 172 can be controlled to close to prevent the coating liquid from being discharged from the water inlet pipe 171. When it is necessary to switch the nozzle 10, the solenoid valve II 173 and the solenoid valve III 177 are controlled to close, and then the solenoid valve I 172 is controlled to open. When the output shaft of the stepping motor 152 rotates one circle, it can drive the cam 1710 to rotate one circle. The cam 1710 drives the limit block 1711 to rotate, turning the limit block 1711 away so that the limit block 1711 no longer limits the slide bar 179. Subsequently, the cam 1710 pushes the slide bar 179 to move to the right. The slide bar 179 drives the water outlet pipe 175 to move to the right, separating the water outlet pipe 175 from the installation pipe 9, and the first spring 176 is stretched. When the sector gear 153 and the full gear 151 are not engaged, the nozzle 10 has been switched. After the cam 1710 rotates one circle, under the action of the first spring 176, the water outlet pipe 175 moves to the left, and the water outlet pipe 175 will be docked with the installation pipe 9. At this time, the nozzle 10 is located in the water outlet pipe 175, and the sealing ring 1712 will contact the installation pipe 9, thereby improving the sealing performance between the water outlet pipe 175 and the installation pipe 9 and preventing the cleaning liquid or clean water from leaking. At this time, the limit block 1711 will limit the slide bar 179, making the water outlet pipe 175 unable to move and ensuring the stability of the docking between the water outlet pipe 175 and the installation pipe 9. Then, the water outlet pipe 175 is connected to the drainage pipe, and the cleaning liquid is injected into the hard pipe 13 through the water inlet pipe 171. The cleaning liquid flows into the nozzle 10 through the flexible pipe 14 and the installation pipe 9, and finally the cleaning liquid will flow into the water outlet pipe 175. At this time, the solenoid valve III 177 is in the closed state, so the cleaning liquid will remain in the hard pipe 13, the flexible pipe 14, the installation pipe 9, the nozzle 10 and the water outlet pipe 175, soaking the hard pipe 13, the flexible pipe 14, the installation pipe 9 and the nozzle 10 to soften the stains inside them for subsequent flushing. After the soaking is completed, the solenoid valve III 177 is controlled to open, and then clean water is injected into the hard pipe 13 through the water inlet pipe 171 to clean the hard pipe 13, the flexible pipe 14, the installation pipe 9 and the nozzle 10. The dirty water is discharged through the water outlet pipe 175. During the cleaning process, another nozzle 10 can be used to spray the photovoltaic panel, and the spraying and cleaning can be carried out simultaneously without stopping the machine for operation, so that the work can be carried out continuously to ensure the work efficiency.

[0038] Refer to Figures 10-12, further comprising a positioning mechanism, the positioning mechanism includes a positioning pin 182 and a second spring 183. The rotary box 8 is circumferentially and evenly spaced with four groups of positioning grooves 181, and each group has six positioning grooves 181. The mounting ring 7 is circumferentially and evenly spaced and slidably connected with four groups of positioning pins 182, and each group has three positioning pins 182. The positioning pins 182 are located in the positioning grooves 181. The rotary box 8 is positioned by six positioning pins 182, which can ensure the stability of the rotary box 8. The positioning pins 182 are sleeved with second springs 183, and the two ends of the second springs 183 are respectively connected with the mounting ring 7 and the positioning pins 182. The second springs 183 are sleeved on the positioning pins 182, which can prevent the second springs 183 from bending.

[0039] When the rotary box 8 rotates, the positioning pins 182 will move out of the positioning grooves 181, and the second springs 183 will be stretched. After the nozzle 10 is switched, the positioning pins 182 will correspond to the positioning grooves 181 again. Under the action of the second springs 183, the positioning pins 182 will insert into the positioning grooves 181 to position the rotary box 8, thereby positioning the nozzle 10 and preventing the angle of the nozzle 10 from shifting.

[0040] The above are only examples of the present invention and are not used to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the prior art well-known to those skilled in the art.
