Description

Technical Field

[0001] The utility model relates to the field of photovoltaic glass production, in particular to a photovoltaic glass film pasting device. Background Art

[0002] Photovoltaic glass coating is a deep processing technology for photovoltaic glass. By laminating an anti-reflection film layer on the surface of the photovoltaic glass, the reflection of sunlight is reduced, the light transmittance of the photovoltaic glass is increased, and the function of improving the photoelectric conversion efficiency of the solar photovoltaic cell module is achieved. The continuous development of the photovoltaic glass coating technology enables the photoelectric conversion efficiency of the solar photovoltaic cell to reach a higher index. The in-depth research of the coating technology and the continuous R & D of the coating equipment are of great significance to the application and development of the photovoltaic solar cell.

[0003] The Chinese utility model patent (CN215750761U) discloses a photovoltaic glass film pasting machine. The user of the photovoltaic glass film pasting machine can rotate the screw clockwise and counterclockwise to adjust the height of the second fixed plate, and at the same time drive the height of the cleaning brush, so as to clean photovoltaic glass with different thicknesses, which can meet different needs and improve the applicability. The soft brush can apply glue on the surface of the first rubber roller. When the photovoltaic glass is rolled by the first rubber roller, the glue can be adhered to the upper surface of the photovoltaic glass, improving the firmness. However, after the glass film is laminated on the photovoltaic glass, there are many bubbles in the middle, resulting in poor lamination. And this photovoltaic glass film pasting machine does not optimize the rolling and lamination between the photovoltaic glass and the glass film. In view of the existing problems, a photovoltaic glass film pasting device is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that there are many bubbles in the middle after the glass film is laminated on the photovoltaic glass in the prior art, and to propose a photovoltaic glass film pasting device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a photovoltaic glass film pasting device, including a chassis and a film pasting mechanism. The film pasting mechanism is arranged above both sides of the chassis. The film pasting mechanism includes two side plates, a roller shaft, and a rotating belt. The two side plates are symmetrically and fixedly installed on both sides above the chassis. The roller shafts are arranged in an array and rotatably installed between the two side plates. The rotating belt is rotatably sleeved outside the roller shafts. Limiting components are arranged in an array at both ends outside the rotating belt, and rubber roller shafts are rotatably installed between the corresponding limiting components at both ends.

[0007] Preferably, the limiting component includes a limiting box and a sliding block. The limiting boxes are fixedly installed in an array on both ends of the outer surface of the rotating belt. An activity groove is formed on one side of the limiting box close to the rubber roller shaft. The sliding block is slidably installed in the activity groove, and the sliding block is rotatably connected to both ends of the rubber roller shaft.

[0008] Preferably, springs are fixedly installed in an array between the inner wall of the limiting box and the sliding block.

[0009] Preferably, it further includes a feeding mechanism, which includes a plurality of rotating shafts. The plurality of rotating shafts are rotatably installed in an array in the middle of the chassis.

[0010] Preferably, a feeding rubber sleeve is fixedly sleeved on each rotating shaft.

[0011] Preferably, it further includes a film supply mechanism, which includes an extension frame and a feeding roller. The extension frame is fixedly installed at the front end of the chassis. The feeding roller is rotatably installed in the middle of the upper end of the extension frame. The glass film is wound around the feeding roller.

[0012] The beneficial effects of a photovoltaic glass film pasting device proposed by the present utility model are as follows:

[0013] 1. By rotatably arranging the rotating belt in the film pasting mechanism on the chassis, it can drive the rubber roller shafts arranged in an array to rotate in contact with the photovoltaic glass. Through the rolling pressure of the dense and continuous rubber roller shafts, the glass film can be closely and evenly attached to the photovoltaic glass, reducing the time and energy consumed by manual film pasting and leveling. At the same time, with the setting of the limiting component, the sliding block slides up and down in the limiting box, and through the elastic force of the spring, it can also adapt to photovoltaic glass of different thicknesses for film pasting operations, and always ensure the contact between the rubber roller shaft and the photovoltaic glass.

[0014] 2. Through the setting of the extension frame and the feeding roller in the film supply mechanism, the glass film can be wound and stored. During use, only by synchronously pulling it along with the photovoltaic glass, the corresponding attachment of the glass film and the photovoltaic glass can be realized, which is more convenient. At the same time, in the feeding mechanism, through the drive of multiple second motors, it can drive the rotation of some rotating shafts and the feeding rubber sleeves, so as to convey the photovoltaic glass, facilitating continuous film pasting operations. At the same time, the feeding rubber sleeve can provide better friction for the photovoltaic glass. When the rotating belt drives the rubber roller shaft and the feeding rubber sleeve to rotate in opposite directions, it can always provide sufficient friction for the photovoltaic glass to move forward.

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Embodiment 1

[0023] Refer to Figures 1-5, A photovoltaic glass film pasting device, including a chassis 1 and a film pasting mechanism 2. The film pasting mechanism 2 is arranged above both sides of the chassis 1. The photovoltaic glass enters from the front end between the chassis 1 and the film pasting mechanism 2. The film pasting mechanism 2 includes two side plates 21, roller shafts 22, and a rotating belt 23. The two side plates 21 are symmetrically and fixedly installed above both sides of the chassis 1. The roller shafts 22 are rotatably installed in an array between the two side plates 21. The roller shafts 22 are used to support the rotating belt 23 and ensure that the rotating belt 23 is always in a tensioned state. A first motor is fixedly installed on the outer side of the side plate 21. The output shaft of the first motor penetrates the side plate 21 and is fixedly connected to the roller shaft 22. The rotating belt 23 is rotatably sleeved outside the roller shaft 22. At both ends of the outer side of the rotating belt 23, a limiting component 24 is arranged in an array. A rubber roller shaft 25 is rotatably installed between the corresponding limiting components 24 at both ends. The rubber roller shaft 25 is made of a flexible material and can always ensure close contact with the glass film 33 above the photovoltaic glass. The limiting component 24 includes a limiting box 241 and a sliding block 242. The limiting boxes 241 are fixedly installed in an array on the outer surface at both ends of the rotating belt 23. An activity groove is opened on one side of the limiting box 241 close to the rubber roller shaft 25. The sliding block 242 is slidably installed in the activity groove. The sliding block 242 is rotatably connected to both ends of the rubber roller shaft 25. A spring 243 is fixedly installed in an array between the inner wall of the limiting box 241 and the sliding block 242. When the rubber roller shaft 25 contacts the photovoltaic glass, due to the thickness of the photovoltaic glass, it will cause the rubber roller shaft 25 to move upward, thereby squeezing the spring 243 and increasing the squeezing force between the rubber roller shaft 25 and the photovoltaic glass, optimizing the film pasting effect of the photovoltaic glass.

[0024] By rotatably arranging the rotating belt 23 in the film pasting mechanism 2 on the chassis 1, it can drive the rubber roller shafts 25 arranged in an array to rotate in contact with the photovoltaic glass. Through the rolling pressure of the dense and continuous rubber roller shafts 25, the glass film 33 can be closely and evenly attached to the photovoltaic glass, reducing the time and energy consumed by manual film pasting and leveling. At the same time, with the setting of the limiting component 24, by sliding the sliding block 242 up and down in the limiting box 241 and through the elastic force of the spring 243, it can also adapt to photovoltaic glass of different thicknesses for film pasting operations and always ensure the contact between the rubber roller shaft 25 and the photovoltaic glass.

[0025] Embodiment 2

[0026] According to Embodiment 1, in Embodiment 1, the rubber roller shafts 25 arranged in an array on the rotating belt 23 can drive the rubber roller shafts 25 to continuously contact the photovoltaic glass when the rotating belt 23 rotates, optimizing the film pasting effect. However, the supply of the photovoltaic glass and the glass film 33 is relatively inconvenient. Referring to Figures 1-5 , As another preferred embodiment of the present invention, on the basis of Embodiment 1, a feeding mechanism 4 is further included.

[0027] The material feeding mechanism 4 includes a plurality of rotating shafts 41. The plurality of rotating shafts 41 are rotatably installed in the middle of the chassis 1 in an array. A second motor is fixedly installed on one side of the chassis 1 in an array. The output shaft of the second motor penetrates through 1 and is fixedly connected to 41. A material feeding rubber sleeve 42 is fixedly sleeved on each rotating shaft 41. The material feeding rubber sleeve 42 is in direct contact with the photovoltaic glass, providing sufficient friction for the photovoltaic glass. It further includes a film feeding mechanism 3. The film feeding mechanism 3 includes an extension frame 31 and a material feeding roller 32. The extension frame 31 is fixedly installed at the front end of the chassis 1. The material feeding roller 32 is rotatably installed in the middle of the upper end of the extension frame 31. The glass film 33 is wound around the material feeding roller 32.

[0028] Through the arrangement of the extension frame 31 and the material feeding roller 32 in the film feeding mechanism 3, the glass film 33 can be wound and stored. During use, only by pulling it synchronously with the photovoltaic glass, the corresponding fitting of the glass film 33 and the photovoltaic glass can be realized, which is more convenient. At the same time, in the material feeding mechanism 4, through the drive of multiple second motors, the rotation of some rotating shafts 41 and the material feeding rubber sleeves 42 can be driven, so as to convey the photovoltaic glass, facilitating continuous film sticking operation. At the same time, the material feeding rubber sleeve 42 can provide good friction for the photovoltaic glass. When the rotating belt 23 drives the rubber roller shaft 25 and the material feeding rubber sleeve 42 to rotate in the opposite direction, sufficient friction can always be provided for the forward conveyance of the photovoltaic glass.

[0029] Working principle: Place the photovoltaic glass at the front end of the chassis 1. First, pull the glass film 33 to fit one end to the front end of the photovoltaic glass, and then appropriately push the photovoltaic glass. At this time, synchronously start the second motor to drive the rotating shaft 41 and the material feeding rubber sleeve 42 to rotate slowly to convey the photovoltaic glass. At this time, start the first motor to drive the roller shaft 22 and the rotating belt 23 to rotate, and ensure that the rotation directions of the roller shaft 22 and the rotating belt 23 are opposite to the rotation direction of the material feeding rubber sleeve 42. At this time, as the photovoltaic glass advances, always ensure that the glass film 33 is attached to the photovoltaic glass, and the rubber roller shaft 25 on the rotating belt 23 rolls the glass film 33 on the photovoltaic glass to optimize the fitting effect of the glass film 33 on the photovoltaic glass.

[0030] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
