Description

Technical Field

[0001] This invention relates to the field of photovoltaic glass coating technology, specifically to a photovoltaic glass coating device for the production of solar cell modules. Background Technology

[0002] Photovoltaic glass is usually produced in one color. To make it more aesthetically pleasing, a colored or patterned film is applied to the back of the glass. In order to make the film have a longer lifespan and better appearance, a back film is usually applied after the main film is applied to the glass.

[0003] Existing film-coating equipment can perform photovoltaic glass film application quickly and easily, with fast application speed and good results; it is simple to use and easy to operate. However, in actual photovoltaic glass film application, this equipment is very likely to cause bubbles or wrinkles in the applied back film, which is unsightly and results in defective products.

[0004] Meanwhile, during the transport process, the glass may fall due to machine vibration or external impact. If the glass is not protected by a clamping device, it may fall. Summary of the Invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a photovoltaic glass coating device for the production of solar cell modules, comprising a flat coating device, a side frame, a clamping device, and an adjuster, wherein the flat coating device is fixedly installed on the top of the side frame, the adjuster is fixedly installed on the outside of the side frame, the adjuster is slidably connected to the clamping device, and an adjusting rod is fixedly connected to the inside of the side frame;

[0006] The adjuster includes a slide rod, one end of which is fixedly connected to a side frame, and the end of the slide rod away from the side frame is fixedly connected to a connecting rod frame. A threaded rod is threadedly connected to the center of the connecting rod frame, and a support is fitted onto one end of the threaded rod. The slide rod passes through the outside of the support. A connecting rod frame is threadedly connected to the outside of the threaded rod, and the connecting rod frame is connected to the slide rod. The other end of the slide rod is fixedly connected to the side frame. Therefore, as the threaded rod rotates, the position of the side frame changes, thereby limiting the vertically placed photovoltaic glass of different thicknesses.

[0007] The gripper includes a gripping assembly, a rotating pressure plate is slidably mounted on the outer side of the gripping assembly, a rotating rod is rotatably mounted inside the rotating pressure plate, and a fixing frame is fixedly connected to the outer side of the rotating rod.

[0008] The flat cover includes a bottom bend rod, one end of which is fixedly connected to a side frame, and a spring strip is fixedly connected to the end of the bottom bend rod away from the side frame. A flat cover plate is fixedly connected to the end of the spring strip away from the bottom bend rod.

[0009] Preferably, a drive roller is rotatably mounted inside the side frame, and a pressure transformer is fixedly connected to the outside of the drive roller. A drive wheel is rotatably mounted at the bottom of the side frame, and the drive wheel is fixedly connected to the drive roller. A belt is drively connected to the outside of the drive wheel. The drive wheel of the drive roller connected to the motor is independent of the other drive wheels. Therefore, the drive wheel of the drive roller connected to the motor drives the belt to rotate, and the belt then drives the other drive wheels to rotate. The other drive wheels play a role in maintaining the force balance transmission of the belt.

[0010] Preferably, a first groove is formed on the inner side of the belt, and an inner sleeve is provided inside the first groove. The top of the inner sleeve is fixedly connected to the fixing frame. A limit frame is fixedly connected to the outer side of the fixing frame.

[0011] Preferably, the inner side of the pressure plate has a second sliding groove. The clamping assembly includes a telescopic rod, the outer side of which is slidably installed inside the second sliding groove. A spring is fixedly connected to the outer side of the telescopic rod, and the end of the spring away from the telescopic rod is fixedly connected to the second sliding groove. A placement plate is fixedly connected to the top of the telescopic rod, and a spring-loaded tab is fixedly connected to the side of the placement plate away from the telescopic rod. The spring-loaded tab is connected to the placement plate, and the telescopic rod connected to the placement plate is connected to the spring. Therefore, the spring will drive the telescopic rod to slide within the second sliding groove, ultimately achieving the clamping, fixing, and transportation functions of the photovoltaic glass.

[0012] Preferably, the pressure transducer includes a pressure transducer blade, the inner side of which is fixedly connected to a drive roller, and a locking block fixedly connected to the outer side of the pressure transducer blade. An inner pressure transducer blade is fixedly installed inside the locking block, and an ejector is disposed on the outer side of the inner pressure transducer blade. The top of the ejector blade is fixedly connected to a side frame. When the photovoltaic glass is driven by an external force, the drive roller, which is frictionally connected to it, rotates. The pressure transducer blade connected to the drive roller then impacts the tail of the ejector blade. The locking block fixedly installed on the opposite side of the pressure transducer blade drives the inner pressure transducer blade, which is fixedly connected to it, to impact the inner pressure transducer blade, thereby ejecting the coating film from the ejector blade.

[0013] Preferably, a single-headed hinge rod is rotatably mounted on the outer side of the flat cover plate, and an edge scraper is fixedly connected to the end of the single-headed hinge rod away from the flat cover plate. The bottom of the edge scraper is fixedly connected to the side frame, and a motor is provided on the top of the side frame.

[0014] Preferably, the output end of the motor is connected to the drive roller via a coupling, and a second threaded rod is sleeved on the outer side of the side frame, with the end of the second threaded rod away from the side frame threadedly connected to the outer frame.

[0015] Preferably, the edge scraper includes a top platform, the bottom of which is fixedly connected to a side frame. A universal ball is fixedly connected inside the top platform, and the outer side of the universal ball is fixedly connected to a single-headed hinge rod. Through the pressure of the photovoltaic glass on the edge scraper, the single-headed hinge rod deflects towards the photovoltaic glass. A flat cover plate is hinged to the other end of the single-headed hinge rod, thus the flat cover plate adheres tightly to the photovoltaic glass, achieving a secondary, even coating of the film applied to the photovoltaic glass surface.

[0016] Preferably, an external rod is fixedly connected to the side of the universal ball joint away from the single-head hinge rod. An adapter is hinged to the end of the external rod away from the universal ball joint, and a scraper plate is fixedly connected to the outer side of the adapter. When the vertically placed photovoltaic glass moves to the outside of the scraper plate and is pressed against it, the adapter connected to the scraper plate rotates on the external rod, causing the surface of the scraper plate to adhere to the surface of the photovoltaic glass. At this point, the scraper plate effectively scrapes and polishes the corners of the photovoltaic glass.

[0017] Preferably, the sprayer includes a spray housing, the top of which is fixedly connected to a side frame, a shower head is fixedly connected to one end of the spray housing, and an air bag is fixedly installed at the end of the spray housing away from the shower head, with a hollow sliding plate inside the air bag.

[0018] Preferably, the outer side of the spray shell has a third sliding groove, the inner side of which is slidably installed with a hollow sliding plate. An elastic bladder is fixedly installed inside the spray shell, and the end of the elastic bladder near the hollow sliding plate is fixedly connected to an air bag. The impact of the pressure blade against the air bag causes the hollow sliding plate inside the air bag to compress the air in the elastic bladder and squeeze the coating solution inside, thus spraying the coating solution from the shower head.

[0019] This invention provides a photovoltaic glass coating apparatus for the production of solar cell modules. It has the following beneficial effects:

[0020] 1. In this photovoltaic glass coating device for producing solar cell modules, the drive wheel of the drive roller connected to the motor is independent of the other drive wheels. Therefore, the drive wheel of the drive roller connected to the motor will drive the belt to rotate, and the belt will drive the other drive wheels to rotate. The other drive wheels play the role of maintaining the force balance transmission of the belt.

[0021] II. The photovoltaic glass coating device for the production of solar cell modules is connected to the placement plate via a spring pull tab, and the telescopic rod connected to the placement plate is connected to a spring. Therefore, the spring will drive the telescopic rod to slide in the second slide groove, ultimately achieving the function of clamping, fixing and transporting the photovoltaic glass.

[0022] Third, the photovoltaic glass coating device for the production of solar cell modules uses two rotating blades fixed on the first drive roller and another drive roller connected to it to rotate in opposite directions and simultaneously impact the sprayer. In addition, the opposite rotation of the two blades also helps to more effectively coat the film sprayed on the surface of the photovoltaic glass.

[0023] IV. The photovoltaic glass coating device for the production of solar cell modules works by moving the vertically placed photovoltaic glass to the outside of the edge scraper and pressing it. The adapter connected to the edge scraper rotates on the external rod, so that the surface of the edge scraper is in contact with the surface of the photovoltaic glass. At this time, the edge scraper plays the role of scraping and polishing the corners of the photovoltaic glass.

[0024] 5. The photovoltaic glass coating device for the production of solar cell modules is also wrapped in an air bag in the part that is driven by the hollow slide plate and the No. 3 slide. Then the hollow slide plate will compress the air in the elastic bag and squeeze the coating solution in the elastic bag, so as to spray the coating solution from the shower head.

[0025] VI. The photovoltaic glass coating device for the production of solar cell modules uses an internal pressure blade to continue impacting the hollow slide plate along the No. 3 slide groove. This causes the hollow slide plate to impact the elastic bladder a second time, causing the coating solution inside the elastic bladder to be sprayed out again, thus achieving the effect of completely spraying out the coating solution inside the elastic bladder.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0037] First embodiment, such as Figures 1-4 As shown, the present invention provides a technical solution: a photovoltaic glass coating device for the production of solar cell modules, including a flat coating device 1, a side frame 2, a clamping device 3 and an adjuster 4. The flat coating device 1 is fixedly installed on the top of the side frame 2, the adjuster 4 is fixedly installed on the outside of the side frame 2, the adjuster 4 is slidably connected to the clamping device 3, and an adjusting rod 5 is fixedly connected to the inside of the side frame 2.

[0038] The adjuster 4 includes a slide rod 41, one end of which is fixedly connected to the side frame 2. The end of the slide rod 41 away from the side frame 2 is fixedly connected to a connecting rod frame 48. A threaded rod 43 is threadedly connected to the center of the connecting rod frame 48. A support 42 is sleeved on one end of the threaded rod 43. The slide rod 41 passes through the outside of the support 42. A drive roller 46 is rotatably installed inside the side frame 2. A pressure transformer 47 is fixedly connected to the outside of the drive roller 46. A drive wheel 45 is rotatably installed at the bottom of the side frame 2. The drive wheel 45 is fixedly connected to the drive roller 46. A belt 44 is drively connected to the outside of the drive wheel 45. When the motor 15 is started, the drive roller 46 connected to it will rotate. Subsequently, the drive roller 46 connected to the motor 15 will drive the other drive rollers 46 to rotate. The drive roller 46 connected to the motor 15 is connected to the drive wheel 45, while the other drive rollers 46 and the drive wheel 45 are not connected. At the same time, the drive wheel 45 of the drive roller 46 connected to the motor 15 is not related to the other drive wheels 45. Therefore, the drive wheel 45 of the drive roller 46 connected to the motor 15 will drive the belt 44 to rotate, and the belt 44 will drive the other drive wheels 45 to rotate. The other drive wheels 45 play the role of maintaining the force balance transmission of the belt 44.

[0039] The vertically placed photovoltaic glass is placed on the adjusting rod 5. Then, by rotating the first threaded rod 43, which is sleeved and connected to the support 42, the first threaded rod 43 will rotate within the support 42. The outer thread of the first threaded rod 43 is connected to the connecting rod 48, which is connected to the sliding rod 41. The other end of the sliding rod 41 is fixedly connected to the side frame 2. Therefore, as the first threaded rod 43 rotates, the sliding rod 41 will cause the position of the side frame 2 to change, thereby limiting the vertically placed photovoltaic glass of different thicknesses.

[0040] The gripper 3 includes a gripping assembly 37. A pressure plate 36 is slidably mounted on the outer side of the gripping assembly 37. A rotating rod 35 is rotatably mounted inside the pressure plate 36. A fixing frame 34 is fixedly connected to the outer side of the rotating rod 35. A first groove 31 is formed on the inner side of the belt 44. An inner sleeve 32 is provided inside the first groove 31. The top of the inner sleeve 32 is fixedly connected to the fixing frame 34. A limit frame 33 is fixedly connected to the outer side of the fixing frame 34.

[0041] The inner side of the pressure plate 36 is provided with a second sliding groove 371. The clamping assembly 37 includes a telescopic rod 373. The outer side of the telescopic rod 373 is slidably installed inside the second sliding groove 371. A spring 372 is fixedly connected to the outer side of the telescopic rod 373. The end of the spring 372 away from the telescopic rod 373 is fixedly connected to the second sliding groove 371. A placement plate 374 is fixedly connected to the top of the telescopic rod 373. A spring pull tab 375 is fixedly connected to the side of the placement plate 374 away from the telescopic rod 373. Before the belt 44 rotates, the horizontally placed photovoltaic glass is first placed on the grippers 3 that are slidably installed inside the belt 44. There are several grippers 3, arranged in pairs facing each other. The horizontally placed photovoltaic glass first presses against the pressure plate 36. At this time, the section of the pressure plate 36 near the belt 44 rotates via the rotating rod 35 and is eventually limited by the limiting frame 33. The section of the pressure plate 36 with the gripping assembly 37 rotates towards the photovoltaic glass. Then, the upper and lower sides of the photovoltaic glass extend into the space between the two placement plates 374. The end face is curved, so the upper and lower sides of the photovoltaic glass will press against the placement plate 374. The other end of the placement plate 374 is fixedly connected to the telescopic rod 373. Therefore, the placement plate 374 will move in the opposite direction to the photovoltaic glass. The circumferential side of the photovoltaic glass will press against the elastic pull piece 375. The elastic pull piece 375 is connected to the placement plate 374. The telescopic rod 373 connected to the placement plate 374 is connected to the spring 372. Therefore, the spring 372 will drive the telescopic rod 373 to slide in the second slide groove 371, ultimately achieving the function of clamping, fixing and transporting the photovoltaic glass.

[0042] Second embodiment, such as Figures 5-9 As shown, the flat cover 1 includes a bottom bending rod 11, one end of which is fixedly connected to the side frame 2. A spring strip 12 is fixedly connected to the end of the bottom bending rod 11 away from the side frame 2. A flat cover plate 13 is fixedly connected to the end of the spring strip 12 away from the bottom bending rod 11. A single-headed hinge rod 14 is rotatably installed on the outer side of the flat cover plate 13. An edge scraper 16 is fixedly connected to the end of the single-headed hinge rod 14 away from the flat cover plate 13. The bottom of the edge scraper 16 is fixedly connected to the side frame 2. A motor 15 is provided on the top of the side frame 2. The output end of the motor 15 is connected to the drive roller 46 through a coupling. A second threaded rod 18 is sleeved on the outer side of the side frame 2. An outer frame 17 is threadedly connected to the end of the second threaded rod 18 away from the side frame 2.

[0043] The pressure transducer 47 includes a pressure transducer blade 471. The inner side of the pressure transducer blade 471 is fixedly connected to the drive roller 46, and a locking block 472 is fixedly connected to the outer side of the pressure transducer blade 471. An inner pressure transducer blade 473 is fixedly installed inside the locking block 472, and an ejector 474 is provided on the outer side of the inner pressure transducer blade 473. The top of the ejector 474 is fixedly connected to the side frame 2. When an external force moves the vertically placed photovoltaic glass along the outer side of the drive roller 46, the drive roller 46 will rotate. Since the pressure transducer blade 471 is fixedly connected to the outer side of the drive roller 46, the pressure transducer blade 471 will impact the tail of the ejector 474. The locking block 472, fixedly installed on the opposite side of the pressure transducer blade 471, will drive the inner pressure transducer blade 473, which is fixedly connected to it, to impact the inner pressure transducer blade 473, thereby spraying the coating film out of the ejector 474.

[0044] When the photovoltaic glass rubs against the outside of the first drive roller 46, the first drive roller 46 will rotate in the forward direction, while the second drive roller 46, which is connected to the first drive roller 46, will rotate in the reverse direction. Therefore, the two rotating blades 471, which are respectively fixed on the first drive roller 46 and the other drive roller 46 connected to it, will rotate in the opposite direction and simultaneously impact the sprayer 474. In addition, the reverse rotation of the two also plays a role in more effectively coating the film sprayed on the surface of the photovoltaic glass.

[0045] The edge scraper 16 includes a top platform 161, the bottom of which is fixedly connected to the side frame 2. A universal ball joint 162 is fixedly connected inside the top platform 161. The outer side of the universal ball joint 162 is fixedly connected to a single-headed hinge rod 14. An external rod 163 is fixedly connected to the side of the universal ball joint 162 away from the single-headed hinge rod 14. An adapter 164 is hinged to the end of the external rod 163 away from the universal ball joint 162. An edge scraper plate 165 is fixedly connected to the outer side of the adapter 164. Furthermore, when the vertically placed photovoltaic glass moves to the outside of the edge scraper plate 165 and is pressed against it, the adapter 164 connected to the edge scraper plate 165 will rotate on the external rod 163, causing the surface of the edge scraper plate 165 to adhere to the surface of the photovoltaic glass. At this time, the edge scraper plate 165 serves to scrape and polish the corner edges of the photovoltaic glass.

[0046] The other end of the external rod 163 is fixedly connected to the universal ball 162, and the other side of the universal ball 162 is connected to the single-head hinge rod 14. Therefore, when the external rod 163 is squeezed by the photovoltaic glass, the single-head hinge rod 14 will deflect towards the photovoltaic glass. The other end of the single-head hinge rod 14 is hinged to the flat cover plate 13, so the flat cover plate 13 will stick tightly to the photovoltaic glass to achieve secondary coating of the film on the surface of the photovoltaic glass and at the same time to remove air bubbles in the film on the surface of the photovoltaic glass.

[0047] The sprayer 474 includes a spray housing 4741, the top of which is fixedly connected to the side frame 2. A shower head 4742 is fixedly connected to one end of the spray housing 4741. An air bag 4743 is fixedly installed at the end of the spray housing 4741 away from the shower head 4742. A hollow sliding plate 4744 is provided inside the air bag 4743. A third sliding groove 4746 is provided on the outer side of the spray housing 4741. The inner side of the third sliding groove 4746 is slidably installed with the hollow sliding plate 4744. An elastic bladder 4745 is fixedly installed inside the spray housing 4741. The end of the elastic bladder 4745 near the hollow sliding plate 4744 is fixedly connected to the air bag 4743. The impact of the pressure blade back 471 on the air bag 4743 causes the gas inside the air bag 4743 to impact the hollow slide plate 4744. The outer side of the hollow slide plate 4744 is slidably connected to the third slide groove 4746, and the outer side of the hollow slide plate 4744 is wrapped inside the air bag 4743. The part of the hollow slide plate 4744 that drives the third slide groove 4746 is also wrapped by the air bag 4743. Subsequently, the hollow slide plate 4744 compresses the air inside the elastic bladder 4745 and squeezes the coating solution inside the elastic bladder 4745, thereby spraying the coating solution out of the shower head 4742.

[0048] Next, the inner pressure blade 473 continues to impact the hollow slide plate 4744 along the third slide groove 4746. This causes the hollow slide plate 4744 to impact the elastic bladder 4745 a second time, causing the coating solution inside the elastic bladder 4745 to spray out again. The rotation of the pressure blade 471 and the inner pressure blade 473 is repeated to completely spray out the coating solution from the elastic bladder 4745. Furthermore, when the vertically placed photovoltaic glass no longer engages in frictional transmission with the drive roller 46 in this section, the drive roller 46 stops rotating, and the coating solution stops spraying out from the elastic bladder 4745.

[0049] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
