[0002] Photovoltaic panels refer to devices that use solar energy to generate electricity. They are mainly composed of a backplane, photovoltaic modules, glass, etc. After the production of photovoltaic panels is completed, they need to be transported or sold as semi-finished products. In order to prevent scratches on the surface of the photovoltaic panels during transportation, a film is often affixed to the surface of the photovoltaic panels to protect them. A film-sticking device is required to stick the film on the photovoltaic panels.

However, the edges of the small photovoltaic panels are curved.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Example 1: Reference Figure 1 , Figure 2 and Figure 5 A photovoltaic panel film pasting device includes: a working platform 1 and a conveying mechanism 101 arranged on the working platform 1, the conveying mechanism 101 can be a conveyor belt but is not limited to a conveyor belt, a mounting plate 102 is fixedly connected to one side of the working platform 1, and a reeling mechanism 106 is arranged on the mounting plate 102, wherein the reeling mechanism 106 is composed of a driving motor and a reeling shaft and a limiting mechanism for limiting the winding roll, and also includes: a first tensioning shaft 107, which is rotatably arranged on the mounting plate 102; a moving platform 2, which is arranged on the working platform 1; a cylinder 201, which is symmetrically fixedly connected between the moving platform 2 and the working platform 1; an air column 3, which is rotatably arranged on the moving platform 2; refer to Figure 2 The cylinder 201 drives the moving platform 2 to move downward, so that the air column 3 is squeezed onto the photovoltaic panel. The lower end of the air column 3 squeezes the film onto the photovoltaic panel, and the deformed air column 3 squeezes the film onto the curved surfaces on the left and right sides of the photovoltaic panel, thereby improving the effect of film pasting on the photovoltaic panel.

[0038] The fixed plate 301 is symmetrically fixedly connected to both sides of the air column 3; the fixed shaft 302 is arranged on the air column 3, and the fixed shaft 302 is colinear with the axis of the air column 3, and both ends of the fixed shaft 302 pass through the fixed plate 301; the second motor 104 is arranged on one side of the moving platform 2, and the output end of the second motor 104 is fixedly connected to the fixed shaft 302; refer to Figure 5 The second motor 104 drives the air column 3 to rotate through the fixed shaft 302, so that the photovoltaic panel can move between the conveying mechanism 101 and the air column 3. The lower end of the rotating air column 3 is in surface contact and extrusion with the photovoltaic panel to improve the compression effect on the film. At the same time, the rotating air column 3 rolls the film to be bonded to the photovoltaic panel to prevent bubbles from appearing during the process of bonding the film to the photovoltaic panel.

[0039] The guide shaft 311 is fixedly arranged on the moving platform 2, and the guide shaft 311 matches the air column 3; Figure 6 The guide shaft 311 guides the film and keeps the film in a tensioned state to prevent the film from wrinkling.

[0040] The film cutting assembly is arranged on the moving platform 2 ; the controller 105 is fixedly arranged on one side of the mounting plate 102 .

[0041] Reference Figure 3 and Figure 6The film cutting assembly includes a top plate 202 fixedly set on the moving platform 2, a visual detection mechanism 203 is fixedly connected to the top plate 202, first linear motors 204 are symmetrically fixedly connected on both sides of the moving platform 2, a second linear motor 205 is fixedly connected between the mover ends of the two first linear motors 204, a limiting block 206 is fixedly connected to the mover end of the second linear motor 205, a limiting rod 207 is fixedly connected between the mover ends of the two first linear motors 204, the limiting block 206 is slidably set on the limiting rod 207, and a cutting knife 208 is fixedly connected to the lower end of the limiting block 206.

[0042] The photovoltaic panels after film pasting are photographed by the visual detection mechanism 203. When the ends of the two photovoltaic panels move to the set position, the controller 105 controls the first linear motor 204 and the second linear motor 205 to drive the cutting knife 208 to follow the cutting of the film between the two photovoltaic panels, and keeps the cutting knife 208 and the moving direction of the photovoltaic panels stationary. The visual detection mechanism 203 uses a camera in the prior art to take pictures, and then analyzes them through the analysis module in the microcomputer.

[0043] Example 2: Reference Figure 4 , Figure 5 and Figure 7 , a photovoltaic panel film pasting device, which is basically the same as Example 1, further, a turntable 4 is rotatably arranged on the mounting plate 102, a first motor 103 is fixedly connected to one side of the mounting plate 102, and the output end of the first motor 103 is fixedly connected to the turntable 4, a second tensioning shaft 401 is fixedly connected to the side of the turntable 4 away from the first motor 103, and the second tensioning shaft 401 is eccentrically arranged on the turntable 4, wherein the first motor 103 adopts a motor that currently does not have a self-locking function.

[0044] A damping ring 402 is fixedly connected to the mounting plate 102 , and the turntable 4 rotates inside the damping ring 402 .

[0045] During the film laminating process, the unwinding mechanism 106 is used for unwinding, and the first motor 103 drives the turntable 4 to rotate at a specified angle and then stop, so that the film wound on the winding roll falls off, and at the same time, the second tensioning shaft 401 is used for tensioning, and the air column 3 continuously adheres to the film. At this time, the film exerts a moving force on the second tensioning shaft 401 under the action of the first tensioning shaft 107, so that it rotates along the axis of the turntable 4. During the rotation of the turntable 4, a certain resistance is provided by the damping ring 402, thereby effectively improving the tensioning effect of the film.

[0046] Example 3: Reference Figure 7, a photovoltaic panel film pasting device, which is basically the same as Example 1, and further, a fixing ring 403 is fixedly connected to the mounting plate 102, and the fixing ring 403 is coaxially arranged with the turntable 4, the turntable 4 is fixedly connected with a first breaking contact conductive block 404, a first detection conductive block 406 and a first triggering conductive block 408, the fixing ring 403 is fixedly connected with a second breaking contact conductive block 405, a second detection conductive block 407 and a second triggering conductive block 409, the first breaking contact conductive block 404 and the second breaking contact conductive block 405 are in the same circuit, and the current signal of the circuit in which they are located is detected by the controller 105, the first detection conductive block 406 and the second detection conductive block 407 are in the same circuit, and the first triggering conductive block 408 and the second triggering conductive block 409 are in the same circuit.

[0047] When the controller 105 detects that the circuit where the first break contact conductive block 404 and the second break contact conductive block 405 are located is energized, the controller 105 controls the first motor 103 to turn off. When the controller 105 detects that the circuit where the first trigger conductive block 408 and the second trigger conductive block 409 are located is energized, the controller 105 controls the first motor 103 to drive the turntable 4 to rotate, thereby achieving precise film discharge and avoiding the film being too tight or too loose when discharging at a fixed output rate.

[0048] Example 4: Reference Fig. 9 , a photovoltaic panel film pasting device, which is basically the same as Example 1, and further, the diameter of the middle part of the air column 3 gradually decreases to the diameter of the two ends of the air column 3, and the two ends of the transverse cutting surface of the air column 3 are arranged in an arc shape.

[0049] When applying film to the photovoltaic panel, the air column 3 on the side close to the guide shaft 311 squeezes the film in an arc shape. At this time, the air column 3 first contacts the film between the guide shaft 311 and the air column 3 and slightly squeezes it. At this time, the middle part of the film between the guide shaft 311 and the air column 3 contacts the photovoltaic panel first, and the films on both sides gradually contact the photovoltaic panel. At this time, the extrusion propulsion surface of the film is effectively increased, thereby effectively preventing the existence of bubbles between the film and the photovoltaic panel.

[0050] Moreover, the air column 3 can effectively prevent the air column 3 from contacting the conveying mechanism 101 while ensuring large-area squeezing of the photovoltaic panel. Large-area squeezing can effectively increase the squeezing time of the air column 3 on the film on the photovoltaic panel, thereby effectively improving the film pasting effect.

[0051] The photovoltaic panels of different thicknesses can be subjected to film pasting treatment by adjusting the contraction length of the cylinder 201 .

[0052] Reference Figure 6 A plurality of rubber shafts 312 are fixedly connected to the moving platform 2 at equal intervals.

[0053] The rubber shaft 312 squeezes and conveys the photovoltaic panel on the conveying mechanism 101 to improve its conveying stability, thereby effectively preventing the photovoltaic panel from shifting when the film is applied to the photovoltaic panel, and effectively preventing the photovoltaic panel from shifting when the air column 3 first contacts and squeezes the end of the photovoltaic panel.

[0054] Example 5: Reference Fig. 9 and Fig.10 , a photovoltaic panel film pasting device, which is basically the same as Example 1, and further, a plurality of thin film pressure sensors 310 are arranged in the air column 3.

[0055] In a specific embodiment, when the air column 3 contacts and squeezes the photovoltaic panel, the pressure signal received by the air column 3 is detected by the thin film pressure sensor 310, and the received pressure signal is transmitted to the microcomputer, so that the squeezing surface of the photovoltaic panel film by the air column 3 can be fed back to the microcomputer, and the squeezing force on the film and the photovoltaic panel can be intuitively judged.

[0056] Reference Figure 6 , Figure 8 and Fig. 9 A gas cylinder 306 is fixedly connected to one side of the mobile platform 2, and a piston rod 307 is sealed and slidably connected inside the gas cylinder 306. An electric telescopic rod 308 is fixedly connected to the mobile platform 2, and a connecting plate 309 is fixedly connected between the output end of the electric telescopic rod 308 and the piston rod 307. An air intake ring 305 is fixedly connected to the mobile platform 2, and one end of the fixed shaft 302 is sealed and rotated in the air intake ring 305, and a connecting pipe 313 is fixedly connected between the air intake ring 305 and the bottom of the gas cylinder 306. A plurality of air intake ports 303 are provided at one end of the fixed shaft 302 close to the air intake ring 305, and a plurality of exhaust ports 304 are provided at one end of the fixed shaft 302 in the air column 3.

[0057] The electric telescopic rod 308 drives the piston rod 307 to slide in the air cylinder 306 through the connecting plate 309. The air cylinder 306 is connected to the air column 3 through the connecting pipe 313, the air intake ring 305, the air intake port 303, the fixed shaft 302 and the exhaust port 304. The piston rod 307 sliding in the air cylinder 306 can adjust the pressure in the air column 3, thereby adjusting the pressure in the air column 3 and the squeezing force on the photovoltaic panel by sliding the piston rod 307 in the air cylinder 306.

[0058] Refer to Figure 1 and Figure 2When the middle extruded surface of the air column 3 moves to the edge of the right side of the photovoltaic panel, that is, the edge of the middle extruded surface of the air column 3 moves between the two photovoltaic panels, the pressure signal received by the film pressure sensor 310 changes. At this time, the microcomputer sends a control signal to the controller 105, and the controller 105 controls the electric telescopic rod 308 to contract, so that the gas in the air cylinder 306 enters the air column 3, increasing the air pressure in the air column 3, so that the film on the curved surface at the end of the photovoltaic panel can be compressed, so that it can better fit the curved surface of the photovoltaic panel.

[0059] When the middle of the air column 3 contacts the next photovoltaic panel to be pasted with film, the gas in the air column 3 is still in a state of increased pressure, so that the film on the curved surface at the front end of the next photovoltaic panel can be pressed tightly to ensure that the films on the edge curved surfaces of the photovoltaic panel are tightly fitted to the photovoltaic panel, thereby effectively improving the effect of pasting film on the photovoltaic panel.

[0060] The middle of the air column 3 first bonds the middle of the film to the next photovoltaic panel, and then gradually bonds to both sides, thereby effectively preventing the film positioning on the upper side of the photovoltaic panel from being affected when bonding to the curved surface of the photovoltaic panel.

[0061] When the air column 3 is completely placed on the next photovoltaic panel, the microcomputer detects the pressure signal of the film pressure sensor 310, thereby obtaining the fitting condition of its extrusion surface, and the controller 105 controls the electric telescopic rod 308 to reset.

[0062] The photovoltaic panel is squeezed by air column 3. When one side of the squeezing surface of the photovoltaic panel by air column 3 moves to between the two photovoltaic panels, the front end of air column 3 pushes the membrane downward, causing the membrane between the two photovoltaic panels to be concave downward with a certain margin, thereby facilitating a close fit between the membrane and the front and rear curved surfaces of the photovoltaic panel.

[0063] When the controller 105 detects the current signal of the circuit where the first detection conductive block 406 and the second detection conductive block 407 are located, the controller 105 controls the electric telescopic rod 308 to contract, thereby increasing the air pressure in the air column 3, limiting the position of the membrane, and preventing the membrane from being lifted off the photovoltaic panel when the second tensioning shaft 401 tensions the membrane.

[0064] In a specific embodiment, an electronic barometer is installed on the air cylinder 306 (not shown in the figure). The air pressure data of the electronic barometer is obtained by the controller 105, so different air pressures can be adjusted when applying film to photovoltaic panels of different thicknesses to achieve film adhesion.

[0065] Embodiment 6: A photovoltaic panel film pasting method mainly comprises the following steps:

[0066] Step 1: The photovoltaic panel is transported by the transport mechanism 101, and the unwinding mechanism 106 unwinds the film;

[0067] Step 2: applying a squeezing force to the photovoltaic panel through the air column 3, and the lower end of the air column 3 is deformed after being squeezed with the photovoltaic panel, so that the film is attached to the photovoltaic panel;

[0068] Step 3: The squeezed air column 3 squeezes the extruded films on both sides of the photovoltaic panel so that the films are attached to the left and right curved surfaces of the photovoltaic panel;

[0069] Step 4: Cut the film between the two photovoltaic panels using the film cutting assembly.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
