Description

Technical Field

[0001] The present application relates to the technical field of film pasting equipment, and in particular to a film pasting device for photovoltaic modules. Background Art

[0002] Solar panels are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect. After the production of solar panels, workers usually use a film-sticking device to wrap a layer of protective film on the surface of the solar panels to protect the solar panels.

[0003] In the related art, the protective film is transported to the top of the solar panel by the transmission device of the film pasting device, and after being heated by the heating device, it is pasted on the surface of the solar panel under the pressure of the pressing device. Since the length of the protective film is greater than the length of the solar panel, the film pasting device often stops moving after each solar panel is pasted, waiting for the staff to cut the protective film. During this process, the heating device continues to heat the broken part of the protective film, resulting in a higher temperature at the broken part of the protective film. The high temperature protective film is easy to produce bubbles when pasted on the solar panel, affecting the quality of the film pasting. Summary of the invention

[0043] See also Figure 1 , Figure 1A schematic structural diagram of a film-applying device for photovoltaic modules in an embodiment of the present application is shown. A film-applying device 1000 for photovoltaic modules provided in an embodiment of the present application includes: a reel (not shown), a shearing component 1200, a pressing component 1400, and a heating component 1500. The reel is used to wind up a reflective film 1100. The shearing component 1200 is arranged on one side of the reel. The shearing component 1200 is used to shear the reflective film 1100. The pressing component 1400 is arranged on the side of the shearing component 1200 away from the reel. The pressing component 1400 is used to attach the free end of the reflective film 1100 to a device to be film-applied (not shown). The heating component 1500 is arranged on the side of the pressing component 1400 away from the shearing component 1200. The heating component 1500 is used to heat the reflective film 1100.

[0044] In the film-painting device 1000 for photovoltaic modules in this embodiment, the heating component 1500 heats the reflective film 1100, and the pressing component 1400 applies pressure to the heated reflective film 1100 so that the free end of the reflective film 1100 is attached to the device to be film-painted. When the reflective film 1100 is attached to the entire device to be film-painted, the shearing component 1200 shears the reflective film 1100 to separate the reflective film 1100 attached to the device to be film-painted from the reflective film 1100 wound on the reel, so as to facilitate filming on other devices to be film-painted. In summary, The film-laminating device 1000 for photovoltaic modules in this embodiment can timely cut the reflective film 1100 attached to the device to be laminated and the reflective film 1100 wound on the reel when the reflective film 1100 has been laminated on the entire device to be laminated by setting the shearing component 1200, thereby avoiding continuous heating of a certain area on the reflective film 1100 by the heating component 1500, ensuring that the heating temperature of each area on the reflective film 1100 is the same, reducing the probability of bubbles generated when the reflective film 1100 is attached to the device to be laminated, and improving the laminating quality.

[0045] In addition, since the film-sticking device 1000 for photovoltaic modules does not need to stop working for a period of time after sticking a piece of film to be applied to the device, waiting for the staff to cut the reflective film 1100, the film-sticking efficiency of the film-sticking device 1000 for photovoltaic modules is also greatly improved.

[0046] It should be further explained that the device to be coated may be a glass panel in a solar panel.

[0047] See also Figure 2 and Figure 3 In some embodiments, the shearing component 1200 includes a shearing piece 1210 and a shearing seat 1220 that are relatively arranged. The shearing piece 1210 can move relative to the shearing seat 1220 toward or away from the shearing seat 1220, and the reflective film 1100 is used to be inserted between the shearing piece 1210 and the shearing seat 1220.

[0048] In this embodiment, the shearing piece 1210 moves toward the direction approaching the shearing seat 1220, and can cut the reflective film 1100 inserted between the shearing piece 1210 and the shearing seat 1220; the shearing piece 1210 moves toward the direction away from the shearing seat 1220, so that the remaining reflective film 1100 on the reel can be attached to a new film-sticking device, and can be inserted between the shearing piece 1210 and the shearing seat 1220 again and cut by the shearing piece 1210.

[0049] In some embodiments, the film-sticking device 1000 for photovoltaic modules also includes an image collector (not shown), which is used to capture image information of the reflective film 1100 inserted between the shearing piece 1210 and the shearing seat 1220, so that the staff can understand the shearing effect of the shearing piece 1210, and then judge whether the shearing piece 1210 needs to be sheared again according to the degree of shearing of the reflective film 1100.

[0050] See also Figure 2 In some embodiments, a shearing member 1210 is provided with shearing teeth 1211 on one side close to the shearing seat 1220 , and the shearing teeth 1211 are used to shear through holes (not shown) on the reflective film 1100 .

[0051] In this embodiment, the shearing teeth 1211 cut through holes on the reflective film 1100. After the reflective film 1100 is attached to the device to be film-attached, the film-attaching device 1000 for photovoltaic modules uses the adhesive force between the reflective film 1100 attached to the device to be film-attached and the device to be film-attached to stretch the entire reflective film 1100, so that stress concentration occurs in the through holes opened on the reflective film 1100, and then the reflective film 1100 is torn into pieces, separating the reflective film 1100 attached to the device to be film-attached from the reflective film 1100 wound on the reel.

[0052] In some embodiments, a plurality of shearing teeth 1211 are provided on the side of the shearing piece 1210 close to the shearing seat 1220, and each shearing tooth 1211 is used to cut a through hole on the reflective film 1100. By opening a plurality of through holes on the reflective film 1100, it is convenient to separate the reflective film 1100 attached to the film-applying device from the reflective film 1100 wound on the reel with a smaller adhesive force.

[0053] In some embodiments, the plurality of shear teeth 1211 are evenly arranged along the width direction or thickness direction of the reflective film 1100 to open through holes penetrating opposite sides of the reflective film 1100 along the width direction or to open through holes penetrating opposite sides of the reflective film 1100 along the thickness direction.

[0054] See also Figure 3In some embodiments, a groove 1221 is provided on a side of the shear seat 1220 close to the shear teeth 1211 , and the groove 1221 is configured to accommodate the shear teeth 1211 when the shearing piece 1210 shears the reflective film 1100 .

[0055] In this embodiment, a groove 1221 for accommodating the shearing teeth 1211 is provided on the shearing seat 1220, so that the shearing teeth 1211 can completely penetrate the reflective film 1100, thereby improving the success rate of the shearing teeth 1211 in cutting a through hole on the reflective film 1100. The above-mentioned success rate of cutting a through hole on the reflective film 1100 refers to the through hole completely penetrating the reflective film 1100.

[0056] In some embodiments, a plurality of grooves 1221 arranged at intervals are provided on one side of the shearing seat 1220 near the shearing teeth 1211, and the plurality of grooves 1221 correspond to the plurality of shearing teeth 1211 one by one, and each groove 1221 is configured to accommodate the corresponding shearing tooth 1211 when the shearing piece 1210 shears the reflective film 1100. By providing the plurality of grooves 1221 and the plurality of shearing teeth 1211, the reflective film 1100 can be supported by means of an isolation piece (not shown) between two adjacent grooves 1221, so that when the shearing teeth 1211 pierce the reflective film 1100, the tensile force generated on the reflective film 1100 is reduced, so that the reflective film 1100 passing through the shearing piece 1210 and the shearing seat 1220 is prevented from being broken by the tensile force, so that the reflective film 1100 on the reel can continue to pass through the gap between the shearing piece 1210 and the shearing seat 1220.

[0057] Please continue reading Figure 3 In some embodiments, a guide groove 1222 is provided on the side of the shearing seat 1220 close to the shearing tooth 1211, and the guide groove 1222 is used to accommodate the reflective film 1100. The reflective film 1100 is configured to move relative to the shearing seat 1220 along the extension direction of the guide groove 1222, and the groove 1221 is provided on the groove wall (not shown) of the guide groove 1222 close to the shearing tooth 1211.

[0058] In this embodiment, the reflective film 1100 is guided by setting a guide groove 1222, so as to avoid the reflective film 1100 from being offset when passing through the gap between the shearing piece 1210 and the shearing seat 1220, thereby ensuring that the reflective film 1100 located between the shearing piece 1210 and the shearing seat 1220 is always facing the shearing piece 1210, so that the shearing piece 1210 can cut the reflective film 1100 easily.

[0059] In some embodiments, the guide groove 1222 is provided with a first arc chamfer (not shown) on one side along its own extension direction, and a second arc chamfer (not shown) on the other side, and the reflective film 1100 enters the guide groove 1222 through the first arc chamfer, and leaves the guide groove 1222 from the second arc chamfer. By respectively providing the first arc chamfer and the second arc chamfer on both sides of the guide groove 1222 along its own extension direction, the wear of the reflective film 1100 at the connection between the two sides of the guide groove 1222 along its own extension direction and the groove wall of the guide groove 1222 on the side close to the shearing teeth 1211 can be reduced when the reflective film 1100 passes through the guide groove 1222.

[0060] See also Figure 2 In some embodiments, the shearing component 1200 includes a first driving member 1230, a power output end of the first driving member 1230 is connected to the shearing member 1210, and the first driving member 1230 is configured to drive the shearing member 1210 to move relative to the shearing seat 1220 toward or away from the shearing seat 1220.

[0061] In this embodiment, by setting the first driving member 1230 to drive the shearing member 1210 to move relative to the shearing seat 1220 toward or away from the shearing seat 1220, the reflective film 1100 inserted between the shearing member 1210 and the shearing seat 1220 can be sheared more efficiently and quickly.

[0062] In some embodiments, the first driving member 1230 can adopt a common linear motion driving device such as a linear motor, a cylinder, etc. to drive the shearing member 1210 to move relative to the shearing seat 1220 toward or away from the shearing seat 1220.

[0063] In some embodiments, the film-sticking device 1000 for photovoltaic modules includes a central controller (not shown), the first driving member 1230 and the image collector are both communicatively connected to the central controller, the central controller reads the image information taken by the image collector, and when the cutting effect of the shearing member 1210 does not meet expectations, the shearing member 1210 is driven again to shear the reflective film 1100 inserted between the shearing member 1210 and the cutting seat 1220.

[0064] In some embodiments, the film-applying device 1000 for photovoltaic modules includes a position detection sensor (not shown), which is communicatively connected to the central controller. When the position detection sensor detects the shearing piece 1210, it transmits a position signal to the central controller. The central controller turns off the first driving member 1230 based on the received position signal to prevent the shearing piece 1210 from getting closer to the shearing seat 1220, thereby reducing the risk of the shearing piece 1210 being squeezed or collided with the shearing seat 1220 and being damaged.

[0065] Optionally, the position detection sensor may be a common position detection device such as an infrared sensor, an ultrasonic sensor, or a laser sensor.

[0066] See also Figure 1 and Figure 4 In some embodiments, the film pasting device 1000 for photovoltaic modules further includes a transmission assembly 1300, and the transmission assembly 1300 includes a first transmission roller 1310 and a second transmission roller 1320 that are spaced apart. The free end of the reflective film 1100 passes through the gap between the first transmission roller 1310 and the second transmission roller 1320, and moves driven by the first transmission roller 1310 and the second transmission roller 1320.

[0067] In this embodiment, the reflective film 1100 is driven to move by the first transmission roller 1310 and the second transmission roller 1320, so that the reflective film 1100 wound on the reel can be gradually pulled out from the reel, thereby making full use of the reflective film 1100 on the reel to be attached to the film-attaching equipment.

[0068] See also Figure 1 and Figure 4 In some embodiments, a reflective surface 1110 and an adhesive surface 1120 are respectively provided on opposite sides of the reflective film 1100, the first transmission roller 1310 is in contact with the reflective surface 1110, the second transmission roller 1320 is in contact with the adhesive surface 1120, and the outer peripheral surface of the first transmission roller 1310 is provided with transmission teeth (not shown).

[0069] In this embodiment, transmission teeth are provided on the outer surface of the first transmission roller 1310 to increase the roughness of the outer surface of the first transmission roller 1310, thereby increasing the friction force when the outer surface of the first transmission roller 1310 contacts the reflective surface 1110, thereby reducing the risk of the reflective film 1100 slipping relative to the first transmission roller 1310.

[0070] In some embodiments, the outer surface of the second transmission roller 1320 is smoothed and polished to reduce the roughness of the outer surface of the second transmission roller 1320, thereby reducing the friction between the outer surface of the second transmission roller 1320 and the bonding surface 1120, thereby reducing the risk of glue peeling on the bonding surface 1120 of the reflective film 1100.

[0071] In other embodiments, a reflective surface 1110 and an adhesive surface 1120 are respectively provided on opposite sides of the reflective film 1100, the first transmission roller 1310 contacts the reflective surface 1110, the second transmission roller 1320 contacts the adhesive surface 1120, and the outer peripheral surface of the first transmission roller 1310 is roughened and frosted.

[0072] See also Figure 4In some embodiments, the transmission assembly 1300 includes a second driving member 1330 and a third driving member 1340. The power output shaft of the second driving member 1330 is connected to the first transmission roller 1310 to drive the first transmission roller 1310 to rotate around its own axis. The power output shaft of the third driving member 1340 is connected to the second transmission roller 1320 to drive the second transmission roller 1320 to rotate around its own axis.

[0073] In this embodiment, by setting the second driving member 1330 and the third driving member 1340, the first transmission roller 1310 and the second transmission roller 1320 can be automatically rotated, thereby automatically, quickly and efficiently driving the reflective film 1100 to move. It should be further explained that the rotation direction of the first transmission roller 1310 is opposite to the rotation direction of the second transmission roller 1320.

[0074] In some embodiments, the second driving member 1330 and the third driving member 1340 may be common driving devices such as servo motors and rotary cylinders.

[0075] In some embodiments, the film-sticking device 1000 for photovoltaic modules includes a speed detection sensor (not shown), and the speed detection sensor, the second drive member 1330 and the third drive member 1340 are all communicatively connected to the central controller. The speed detection sensor is used to detect the moving speed of the reflective film 1100 and transmit the detected speed information to the central controller. The central controller adjusts the second drive member 1330 and the third drive member 1340 according to the received speed information so that the rotation speed of the first transmission roller 1310 and the rotation speed of the second transmission roller 1320 reach a preset value.

[0076] See also Figure 1 In some embodiments, the film-applying device 1000 for photovoltaic modules includes a plurality of transmission assemblies 1300 arranged at intervals, and the free end of the reflective film 1100 passes through the gap between the first transmission roller 1310 and the second transmission roller 1320 in each transmission assembly 1300, and moves driven by the first transmission roller 1310 and the second transmission roller 1320.

[0077] In this embodiment, a plurality of transmission assemblies 1300 are arranged at intervals. When the reflective film 1100 is relatively long, the free end of the reflective film 1100 is passed through the gap between the first transmission roller 1310 and the second transmission roller 1320 in each transmission assembly 1300 to tension the reflective film 1100.

[0078] In some embodiments, multiple transmission components 1300 are arranged at intervals along the direction of the reel pointing to the clamping component 1400, each transmission component 1300 is arranged between the reel and the clamping component 1400, and the shearing component 1200 is arranged on the side of any transmission component 1300 close to the clamping component 1400.

[0079] In some embodiments, the pressing component 1400 includes a pressing wheel 1420, which can move toward or away from the device to be filmed relative to the device to be filmed, so as to apply pressure to the free end of the reflective film 1100 between the pressing wheel 1420 and the device to be filmed, thereby attaching the reflective film 1100 to the device to be filmed.
