Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module adhesive removal technology, and in particular to a photovoltaic module backsheet adhesive removal device. Background Technology

[0002] To improve safety during transport, adhesive is applied to the surface of solar cells before a protective frame is attached. After the protective frame is removed upon arrival at the destination, a large amount of adhesive residue remains on the solar cells. This residue needs to be removed before the solar cells are used.

[0003] Chinese Patent Publication No. CN219745713U discloses a photovoltaic module adhesive removal device, comprising: a feeding mechanism for moving the solar cells to be treated along a working path; a pretreatment mechanism including a heating component and a spraying component, the heating component forming a heating zone on the working path; and an adhesive scraping mechanism disposed behind the pretreatment mechanism on the working path for scraping off residual adhesive on the solar cells to be treated after spraying adhesive remover. This invention sequentially performs heating treatment and adhesive removal agent spraying, reducing the adhesion of residual adhesive to the solar cells, allowing the adhesive scraping mechanism to quickly scrape off the residual adhesive, preventing scratches or damage to the solar cells during the cleaning process, and improving the efficiency of residual adhesive removal.

[0004] However, the above technical solution has the following shortcomings: when using the equipment to remove adhesive from photovoltaic modules, most of the adhesive remover sprayed on the photovoltaic modules will be removed by its own gravity and the action of the conveyor belt, which prevents the adhesive remover and glue from reacting fully. This results in the scraping mechanism not being able to scrape off the glue completely, thus affecting the adhesive removal quality of the equipment. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a photovoltaic module backsheet adhesive removal device that ensures sufficient reaction between the adhesive and the adhesive remover by reducing the contact area between the conveyor roller and the photovoltaic module and by applying the adhesive remover to the photovoltaic module.

[0006] The technical solution of this utility model is a photovoltaic module backsheet adhesive removal device, comprising: a base frame on which a heating cover, an adhesive removal cover, an intermediate conveying component, and two sets of conveying components are arranged. The intermediate conveying component is located between the two sets of conveying components, and the two sets of conveying components are respectively located below the heating cover and the adhesive removal cover.

A coating component is arranged on the base frame and includes multiple cleaning rollers arranged rotatably on the base frame, and a reagent tank, a pressure pump, a connecting pipe, and multiple water outlet plates arranged on the base frame and connected in sequence. The multiple water outlet plates are located one-to-one below the multiple cleaning rollers. The multiple cleaning rollers are respectively located between the first-step conveying roller and the second-step conveying roller. Each of the multiple cleaning rollers is coaxially arranged with a pulley, and a transmission belt is arranged on the multiple pulleys and the multiple pulleys.

[0007] Preferably, the heating cover is provided with a heating box and heating pipes that are interconnected, the heating cover and the base frame cooperate to form a heating cavity, and the heating pipes are connected to the heating cavity.

[0008] Preferably, two sets of sealing components are slidably arranged on the heating cover. The sealing components include a sealing plate slidably arranged on the heating cover, and a roller b and multiple rollers a rotatably arranged on the sealing plate. The multiple rollers a are all in rotational contact with the heating cover, and the roller b is in rotational contact with the conveying component.

[0009] Preferably, the conveyor assembly includes a motor mounted on a base frame, a drive roller and a driven roller mounted on the base frame, and a transmission belt mounted on the drive roller and the driven roller, both of which are made of high-temperature resistant material.

[0010] Preferably, the adhesive removal cover and the base frame cooperate to form an adhesive removal chamber, which is connected to the heating chamber, and the adhesive removal cover is provided with multiple rubber strips.

[0014] The user places the photovoltaic module onto the conveying assembly. Two conveying assemblies and an intermediate conveying assembly sequentially transport the photovoltaic module into the heating hood and the descaling hood. After the photovoltaic module is heated to a suitable temperature in the heating hood, the conveying assembly transports the photovoltaic module to the intermediate conveying assembly in the descaling hood. A pressure pump sprays the descaling agent in the agent tank onto the cleaning brush through a connecting pipe and a water outlet plate. Driven by multiple pulleys, the cleaning roller applies the descaling agent to the photovoltaic module, thus preventing the descaling agent adhering to the photovoltaic module from dripping onto the bottom frame.

[0021] Example 1

[0022] like Figure 1-Figure 5As shown, the photovoltaic module backsheet adhesive removal device proposed in this embodiment includes a base frame 1 and an application assembly. The base frame 1 is provided with a heating cover 15, an adhesive removal cover 21, an intermediate conveying assembly, and two sets of conveying assemblies. The intermediate conveying assembly is located between the two sets of conveying assemblies, and the two sets of conveying assemblies are respectively located below the heating cover 15 and the adhesive removal cover 21. The intermediate conveying assembly includes a motor b6 mounted on the base frame 1, and a first-step conveying roller 7 and multiple second-step conveying rollers 8 that are alternately rotated on the base frame 1. The motor b6 is driven by the first-step conveying roller 7, and multiple pulleys 28 are coaxially mounted on the first-step conveying roller 7.

[0023] The application assembly is mounted on the base frame 1. The application assembly includes multiple cleaning rollers 9 that are rotatably mounted on the base frame 1, as well as a reagent tank 11, a pressure pump 12, a connecting pipe 13, and multiple water outlet plates 14 that are mounted on the base frame 1 and connected in sequence. The multiple water outlet plates 14 are located below the multiple cleaning rollers 9. The multiple cleaning rollers 9 are located between the first step conveyor roller 7 and the second step conveyor roller 8. The cleaning roller 9 includes a cleaning drum 91 and multiple cleaning brushes 92 that are arranged circumferentially on the cleaning roller 9. The multiple cleaning rollers 9 are all coaxially mounted with pulleys 29. The multiple pulleys 29 are all different in style. The multiple pulleys 28 and the multiple pulleys 29 are all equipped with a drive belt.

[0024] The conveying assembly includes a motor 2 mounted on a base frame 1, a drive roller 3 and a driven roller 4 mounted on the base frame 1, and a transmission belt 5 mounted on the drive roller 3 and the driven roller 4. Both transmission belts 5 are made of high-temperature resistant material.

[0025] In this embodiment, the user places the photovoltaic module onto the conveying assembly. The two conveying assemblies and the intermediate conveying assembly sequentially convey the photovoltaic module into the heating cover 15 and the adhesive removal cover 21. After the photovoltaic module is heated to a suitable temperature in the heating cover 15, the conveying assembly conveys the photovoltaic module to the intermediate conveying assembly in the adhesive removal cover 21. The pressurizing pump 12 sprays the adhesive remover in the agent tank 11 onto the cleaning brush 92 through the connecting pipe 13 and the water outlet plate 14. Driven by the multiple pulleys 28, the cleaning roller 9 applies the adhesive remover to the photovoltaic module, thereby making it difficult for the adhesive remover adhering to the photovoltaic module to drip onto the base frame 1. Furthermore, the first-step conveying roller 7 and the second-step conveying roller 8 reduce the contact area with the photovoltaic module, thereby allowing the adhesive to react with sufficient adhesive remover and improving the adhesive removal quality.

[0026] Example 2

[0027] like Figure 1 , Figure 2 and Figure 4As shown in the figure, the photovoltaic module backsheet adhesive removal device proposed in this embodiment, compared with the first embodiment, has a heating box 16 and a heating pipe 17 that are interconnected on the heating cover 15. The heating cover 15 and the base frame 1 cooperate to form a heating cavity, and the heating pipe 17 is connected to the heating cavity.

[0028] Two sets of sealing components are slidably arranged on the heating cover 15. The sealing components include a sealing plate 18 slidably arranged on the heating cover 15, and a roller b20 and multiple rollers a19 rotatably arranged on the sealing plate 18. The multiple rollers a19 are all in rotational contact with the heating cover 15, and the roller b20 is in rotational contact with the conveying component.

[0029] In this embodiment, the heating box 16 delivers heated air into the heating chamber. Then, two sets of sealing components reduce the rate at which the heated air escapes to the outside, thus reducing the energy consumed in heating the photovoltaic module. When the photovoltaic module moves through the conveying components, the roller b20 contacts the photovoltaic module. Under the push of the conveying components, the photovoltaic module pushes the sealing plate 18 upward through the roller b20. The roller a19 reduces the friction of the sealing plate 18 during movement. When the photovoltaic module is completely inside the heating chamber, the sealing plate 18 resets under its own gravity, thereby reducing the rate of temperature rise near the device.

[0030] Example 3

[0031] like Figure 1 , Figure 2 and Figure 5 As shown in the figure, the photovoltaic module backsheet adhesive removal device proposed in this embodiment, compared with the first embodiment, in this embodiment, the adhesive removal cover 21 and the base frame 1 cooperate to form an adhesive removal chamber, the adhesive removal chamber is connected to the heating chamber, and multiple rubber strips 27 are provided on the adhesive removal cover 21.

[0032] A ventilation assembly 22 is provided on the adhesive removal cover 21, and the ventilation assembly 22 is connected to the adhesive removal chamber. A lower pressure frame 23 is slidably arranged on the adhesive removal cover 21, and a spring 24 is provided between the lower pressure frame 23 and the adhesive removal cover 21. Multiple lower pressure rollers 25 are rotatably arranged on the lower pressure frame 23, and rubber sleeves 26 are provided on the outer circumference of each of the multiple lower pressure rollers 25.

[0033] In this embodiment, the adhesive remover commonly uses chemical materials such as acetone. Acetone evaporates at a temperature of about 55 degrees Celsius. The ventilation component 22 discharges the evaporated chemical gas to the corresponding waste gas recovery component to avoid chronic poisoning of workers. After the photovoltaic module moves to the position of the scraper 10, the spring 24 drives the lower roller 25 on the lower pressure frame 23 to move towards the photovoltaic module until multiple rubber sleeves 26 press against the photovoltaic module, so that the scraper 10 can thoroughly clean the adhesive on the photovoltaic module.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
