Description

Technical Field

[0001] This application relates to the field of photovoltaic solar panel processing equipment technology, and in particular to an automatic film peeling and backsheet mounting composite equipment. Background Technology

[0002] In the field of photovoltaic (PV) module manufacturing, significant progress has been made in the processing technology of PV cells and backsheets with continuous technological advancements. As the core component of a solar power generation system, every step in the production process of PV modules is crucial. The peeling of the PV cell film and the application of adhesive to the backsheet are key steps in PV module production, directly impacting the module's performance and quality. The peeling process provides a clean bonding surface for subsequent backsheet mounting, while the adhesive application provides the necessary adhesion. These technological advancements have made PV module production more efficient and reliable, driving the development of the solar power generation industry.

[0003] A Chinese patent with authorization announcement number CN205542722U discloses a solar cell film peeling device, comprising: a conveying device for transporting silicon wafers, a protective film separation pretreatment mechanism, and a film peeling mechanism. The conveying device conveys the silicon wafers processed by the protective film separation pretreatment mechanism to the film peeling mechanism. This invention pre-separates the protective film from the corresponding photosensitive film on the upper and lower surfaces of the silicon wafer.

[0004] A Chinese patent with authorization announcement number CN222564259U discloses a high-efficiency automatic adhesive application device for photovoltaic module backsheets. It uses a geared motor, a crossbar, a first bevel gear, and a second bevel gear to drive a rotating rod to rotate. The rotating rod, a fixed cylinder, and a rectangular plate drive a vertical rod to rotate. The vertical rod drives a cleaning wipe to rotate, which cleans the dust on the surface of the photovoltaic backsheet. Then, the automatic adhesive application component applies adhesive to the photovoltaic backsheet, thereby reducing the impact of dust on the adhesion strength of the adhesive.

[0005] The aforementioned technologies have the following drawbacks: although they can peel off the film from photovoltaic cells and apply adhesive to the backsheet separately, they lack the function of directly mounting the two together, which needs to be improved. Utility Model Content

[0039] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0040] This application mainly adopts a mounting chamber and corresponding guide rails and drive mechanism to realize the mounting of photovoltaic cells and backsheets, achieving the effect of directly mounting the photovoltaic cells and backsheets after the film is peeled off and the adhesive is applied. The following is a further detailed description of this application.

[0041] Example

[0042] Reference Figure 1 The automatic film peeling and backing plate mounting laminating equipment provided in this application includes a film peeling production line 1, an adhesive application production line 2, and a mounting chamber 3 at their intersection. In this embodiment, the film peeling production line 1 and the adhesive application production line 2 are arranged perpendicularly to each other, and the mounting chamber 3 is provided at the perpendicular intersection. Furthermore, an extension platform 31 is provided between the mounting chamber 3 and both the film peeling production line 1 and the adhesive application production line 2 for connecting the film peeling production line 1 and the adhesive application production line 2, and for installing other components.

[0043] Reference Figure 2A lower guide rail 11 is fixedly installed on the extension platform 31 at the output end of the film-peeling production line 1. A lower support tray 12 is slidably connected to the lower guide rail, and a downward traveling mechanism (not shown in the figure) is connected between the lower guide rail and the lower support tray 12. The downward traveling mechanism is used to drive the lower support tray 12 to slide along the lower guide rail 11. The lower support tray 12 is used to support the photovoltaic cells that have been peeled off, and the end of the lower guide rail 11 extends into the mounting chamber 3. Specifically, the lower guide rail 11 is usually made of high-strength metal material, such as stainless steel, and its shape is generally long and narrow with a smooth surface to reduce the friction when the lower support tray 12 slides. The lower support tray 12 can be a flat structure with a groove at the bottom that matches the lower guide rail 11. The groove can be a dovetail groove, etc. The sliding of the lower support tray 12 is achieved through the cooperation of the groove and the lower guide rail 11. The lower traveling mechanism can be a motor-driven chain transmission mechanism, in which the motor drives the chain to rotate and the chain is connected to the lower support tray 12, thereby driving the lower support tray 12 to slide; or it can be a screw and nut transmission mechanism, in which the motor drives the screw to rotate and the nut is connected to the lower support tray 12, thereby realizing the movement of the lower support tray 12.

[0044] A rotating seat 13 is provided between the film-peeling production line 1 and the lower guide rail 11. The rotating seat 13 can be a disc-shaped structure with a bearing at the bottom to facilitate its rotation. The rotating seat 13 is connected to a rotation drive (not shown in the figure) for driving its own rotation. The rotation drive can be a motor, and the output shaft of the motor is connected to the rotating seat 13. The rotation of the motor drives the rotating seat 13 to rotate. A longitudinal adjustment drive 14 is connected to the top of the rotating seat 13. The longitudinal adjustment drive 14 can be an electric push rod. The extension and retraction of the electric push rod realizes the raising and lowering of the transfer arm 15. A clamping mechanism 16 is provided at the end of the transfer arm 15 for transferring the peeled photovoltaic cells from the film-peeling production line 1 to the lower support tray 12.

[0045] The clamping mechanism 16 includes a pair of clamping plates 161 and a lateral adjustment drive 162 for driving the extension and retraction of the two clamping plates 161. The clamping plates 161 are generally rectangular plates made of plastic or metal, and may also have rubber pads on their surfaces to increase friction against the photovoltaic cells and prevent them from slipping. The lateral adjustment drive 162 can be a cylinder, with its piston rod connected to the clamping plates 161. The extension and retraction of the cylinder opens and closes the two clamping plates 161, thereby clamping and releasing the photovoltaic cells.

[0046] Reference Figure 3An upper guide rail 21 is fixed above the extension platform 31 at the output end of the adhesive application line 2. An upper gripper 22 is slidably connected to the upper guide rail 21. An upper traveling mechanism (not shown in the figure) connects the upper guide rail 21 and the upper gripper 22. The upper traveling mechanism drives the upper gripper 22 to slide along the upper guide rail 21, and the end of the upper guide rail 21 also extends into the application chamber 3. The material and structure of the upper guide rail 21 are similar to those of the lower guide rail 11, and it also has good sliding performance. The shape of the upper gripper 22 can be designed according to actual needs, generally a frame structure to reduce its own weight. The working principle of the upper traveling mechanism is similar to that of the lower traveling mechanism, and it can also adopt chain drive or screw and nut drive. The lifting drive 23 can be a cylinder drive, with the piston rod of the cylinder connected to the adsorption component 24, and the lifting of the adsorption component 24 is achieved by the extension and retraction of the cylinder; or it can be an electric push rod drive, with the extension and retraction of the electric push rod driving the adsorption component 24 to move up and down.

[0047] In other embodiments, the lower and upper traveling mechanisms can also employ synchronous belt drive mechanisms. A synchronous belt drive mechanism includes a synchronous pulley and a synchronous belt. A motor drives the synchronous pulley to rotate, which in turn drives the synchronous belt. The synchronous belt is connected to the lower support tray 12 or the upper gripper 22, enabling their sliding. Synchronous belt drives offer advantages such as smooth transmission and low noise, improving the stability of equipment operation. Furthermore, synchronous belts are available in various materials, allowing for the selection of suitable belts based on different working environments, such as neoprene synchronous belts and polyurethane synchronous belts.

[0048] Reference Figure 4 Inside the mounting chamber 3, the upper gripper 22 is positioned above the lower support tray 12. The bottom of the upper gripper 22 is connected to the adsorption component 24 via the lifting drive 23. The adsorption component 24 is used to adsorb the backsheet that has been glued, and the lower support tray 12 is used to place the photovoltaic cells that have been peeled off. This setup allows the photovoltaic cells to be directly mounted inside the mounting chamber 3 after the film has been peeled off and the backsheet has been glued, improving production efficiency and reducing intermediate steps.

[0049] Reference Figure 5 The adsorption assembly 24 includes a mounting frame 241, a suction cup 242, and a pneumatic control unit (not shown in the figure). The mounting frame 241 is typically a rectangular frame structure made of lightweight materials such as aluminum alloy to facilitate connection with the lifting drive 23. The suction cup 242 can be a circular suction cup made of rubber, which has good adsorption performance. The pneumatic control unit can be a combination of an air pump and a solenoid valve. The air pump provides the air source, and the solenoid valve controls the flow of gas, thereby controlling the negative pressure state inside the suction cup 242.

[0050] Reference Figure 5Specifically, the mounting frame 241 has a mounting hole 250 at its bottom, which is generally circular with threads on its inner wall. The suction cup 242 has a mounting tube 25 connected to the inside of the suction cup 242. The outer wall of the mounting tube 25 is also threaded. The suction cup 242 is detachably mounted on the mounting frame 241 via the threaded connection between the mounting tube 25 and the mounting hole 250. Furthermore, the mounting frame 241 has an air hole 26 at its top, which is connected to the air control unit via an air tube. The air hole 26 is connected to both the mounting hole 250 and the mounting tube 25. Thus, the air control unit can draw air into or inflate the suction cup 242 via the air tube, enabling the suction cup 242 to adhere to and release the backplate.

[0051] Furthermore, a coaxial sealing ring 27 is provided at the end of the mounting tube 25. The sealing ring 27 is usually made of rubber, and its function is to prevent gas leakage and improve the adsorption effect of the suction cup 242. When the mounting tube 25 is threadedly connected to the mounting hole 250, the sealing ring 27 abuts tightly against the inner wall of the mounting hole 250 to form a sealing structure.

[0052] Reference Figure 1 The mounting chamber 3 has a stacking position 32 on its side, which is used to store the mounted photovoltaic modules. The end of the upper guide rail 21 passes through the mounting chamber 3 and extends above the stacking position 32, facilitating the transportation of the mounted photovoltaic modules to the stacking position 32. Limiting corner plates 33 are provided at the four corners of the stacking position 32. The limiting corner plates 33 are generally right-angled triangular structures made of metal, and their function is to limit the stacked photovoltaic modules, preventing them from tipping over or shifting.

[0053] The implementation principle of this embodiment is as follows: During the photovoltaic module production process, the film-peeling production line 1 peels the photovoltaic cells, and the adhesive-applying production line 2 applies adhesive to the backsheet. After peeling, the photovoltaic cells are transferred to the lower support tray 12, and then the lower traveling mechanism drives the lower support tray 12 along the lower guide rail 11 to transport the photovoltaic cells into the mounting chamber 3. Simultaneously, the adhesive-applying backsheet is adsorbed by the adsorption component 24, and the upper traveling mechanism drives the upper gripper 22 along the upper guide rail 21 to transport the backsheet into the mounting chamber 3, positioned above the photovoltaic cells. Then, the lifting drive 23 lowers the adsorption component 24, causing the backsheet to adhere to the photovoltaic cells, completing the mounting process. After mounting, the upper traveling mechanism lifts the mounted photovoltaic module and transports it to the stacking position 32 for stacking. The entire process achieves integrated operation of photovoltaic cell film peeling, backsheet adhesive application, and both mounting, improving production efficiency, reducing manual intervention, and lowering production costs, representing an effective improvement over existing technologies.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
