DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] In the photovoltaic field, photovoltaic products usually include a backplane, a glass plate covering the backplane, and a number of cells located between the two. Film tapes are attached to the gaps between the cells. The film tapes reflect the light energy irradiated into the gaps between the cells onto the glass plate, and then reflect it to the cells through the glass plate, so as to fully utilize the light energy in the gaps between the cells and improve the light energy utilization rate of photovoltaic products.

[0033] At present, there is usually no film testing process after the film is applied to the photovoltaic backplane. Instead, after the backplane, glass panel, etc. are assembled to form a photovoltaic product, testing equipment is used to test the film application of the photovoltaic product. Once a film application problem is found, the photovoltaic product needs to be disassembled and the photovoltaic backplane needs to be re-filmed, which makes the film application rework process of the photovoltaic product complicated.

[0034] In view of the above problems, the film pasting equipment provided by the embodiment of the present disclosure includes a conveying device, a film pasting device and a detection system. The conveying device includes an input end, an output end and a conveying surface, and the conveying surface is used to transport the photovoltaic backboard between the input end and the output end. The film pasting device is located on one side of the conveying surface and is arranged between the input end and the output end. The film pasting device is used to apply a reflective film strip to the photovoltaic backboard. The film pasting equipment is provided with a detection station, and the detection station is arranged at the output end, which means that the detection station is at the output end, or the detection station is at the side of the output end away from the input end. If the detection station is at the output end, the conveying device includes a first conveying part and a second conveying part, and the first conveying part and the second conveying part are arranged at intervals, and the detection station is between the first conveying part and the second conveying part. Of course, other effective implementation methods can also be used. The detection station and the conveying surface are located in the same plane, and the detection station has a first side and a second side opposite to each other. The detection system includes: a light source component, a detection component and an information processing device. The light source assembly is arranged at the first side of the detection station, and is configured to emit light toward the detection station, and the light passes through the photovoltaic backboard, and projects the photovoltaic backboard onto the second side of the detection station. The detection assembly is arranged at the second side of the detection station, and is configured to collect the projected image of the photovoltaic backboard. The information processing device is connected to the detection assembly signal, and is used to receive and process the information collected by the detection assembly.

[0035] After the film pasting device affixes the reflective film tape to the photovoltaic back panel, the detection system utilizes the light source component and the detection component to realize the acquisition of the projection image of the photovoltaic back panel, and utilizes the information processing device to receive and process the information of the detection component, so as to realize the detection and processing of the film pasting condition after the reflective film tape is affixed to the photovoltaic back panel. Once the film pasting problem is found, the photovoltaic back panel can be immediately reworked, and the rework process is simple.

[0036] The specific structure of the film sticking equipment is described below in conjunction with an embodiment.

[0037] Figure 1 Shown is a schematic structural diagram of a film pasting device provided in one embodiment of the present disclosure. Figure 2 FIG. 1 is a schematic diagram of the structure of a detection system provided by an embodiment of the present disclosure. Figure 1 and Figure 2As shown, the film pasting device 120 includes a conveying device 121, a film pasting device 122 and a detection system 123. The conveying device 121 includes a conveying surface 1211, an input end 1212 and an output end 1213. The conveying surface 1211 is used to transport the photovoltaic back panel between the input end 1212 and the output end 1213. The film pasting device 122 is located on one side of the conveying surface 1211 and is arranged between the input end 1212 and the output end 1213. The film pasting device 122 is used to apply a reflective film strip to the photovoltaic back panel. The film pasting device 120 is provided with a detection station 1214. The detection station 1214 is arranged on the side of the output end 1213 away from the input end 1212 and is located in the same plane as the conveying surface 1211. The detection station 1214 has a first side and a second side opposite to each other. The detection system 123 includes: a detection component 1, a light source component 2 and an information processing device 3. The light source assembly 2 is disposed on the first side of the detection station 1214, and the light source assembly 2 is configured to emit light toward the detection station 1214, and the light passes through the photovoltaic backsheet, and projects the photovoltaic backsheet on the second side of the detection station 1214. The detection assembly 1 is disposed on the second side of the detection station 1214, and the detection assembly 1 is configured to collect the projected image of the photovoltaic backsheet. The information processing device 3 is connected to the detection assembly 1 by signal, and the information processing device 3 is used to receive and process the information collected by the detection assembly 1.

[0038] After the film pasting device 122 affixes the reflective film to the photovoltaic backboard, the detection system 123 utilizes the light source component 2 and the detection component 1 to capture the projection image of the photovoltaic backboard, and utilizes the information processing device 3 to receive and process the information of the detection component 1, so as to detect and process the film pasting condition after the reflective film is affixed to the photovoltaic backboard. Once a film pasting problem is found, the photovoltaic backboard can be reworked immediately, and the rework process is simple and fast.

[0039] In some embodiments, Figure 2 and Figure 3 As shown, the detection assembly 1 includes a first adjustment assembly 10 and a detection device 20. The first adjustment assembly 10 is arranged at the second side of the detection station. The detection device 20 is connected to the first adjustment assembly 10, and the information processing device 3 is signal-connected. The detection device 20 is configured to collect the projection image of the photovoltaic backsheet. The first adjustment assembly 10 is configured to adjust the posture of the detection device 20. The posture of the detection device 20 is adjusted by the first adjustment assembly 10 so that the detection device 20 can collect the projection image of the photovoltaic backsheet at the best angle, thereby improving the collection accuracy.

[0040] In some embodiments, the first adjustment assembly 10 includes: a support plate 100, a mounting plate 200 and a locking assembly 300, the mounting plate 200 is rotatably connected to the support plate 100, the mounting plate 200 is configured to install the detection device 20, the locking assembly 300 is detachably connected to the mounting plate 200 and the support plate 100, and the locking assembly 300 is configured to fix the relative position of the support plate 100 and the mounting plate 200. In other words, when the rotation angle of the mounting plate 200 relative to the support plate 100 meets the preset angle, the locking assembly 300 locks the mounting plate 200 and the support plate 100. The structure is simple and the adjustment method is simple.

[0041] Exemplarily, the mounting plate 200 may be rotatably connected to the support plate 100 via a pin 1900 .

[0042] For example, Figure 3 and Figure 4 As shown, the detection device 20 may include a camera 201, which is disposed on a mounting plate 200 and fixedly connected to the mounting plate 200. The camera 201 may be non-detachably connected to the mounting plate 200 by welding, bonding, etc., or the camera 201 may be detachably connected to the mounting plate 200 by bolts, nuts, screws, buckles, magnets, etc.

[0043] Exemplarily, the detection device 20 may further include a protective cover 202 , which is disposed on the periphery of the camera 201 and connected to the mounting plate 200 , for protecting the camera 201 .

[0044] The specific value of the preset angle can be determined according to actual needs, and the present disclosure does not make specific limitations. In practical applications, the preset angle is generally determined during the debugging process of the detection device 20. For example, when the preset angle determined during the debugging process of the detection device 20 is 5°, when the rotation angle of the mounting plate 200 relative to the support plate 100 is 5°, the locking assembly 300 can be used to lock the mounting plate 200 and the support plate 100.

[0045] In some embodiments, the first adjustment assembly 10 further includes: a first fixing member 400 and at least one first adjustment member 500, the first fixing member 400 is connected to the support plate 100 and is located on one side of the mounting plate 200, and the at least one first adjustment member 500 is screwed to the first fixing member 400 and abuts against the side of the mounting plate 200 to make the adjustment more precise. The first adjustment member 500 applies a thrust to the mounting plate 200 to rotate the mounting plate 200 relative to the support plate 100, and the direction of the thrust applied by the first adjustment member 500 to the mounting plate 200 does not pass through the rotation center of the mounting plate 200 and the support plate 100.

[0046] For example, Figure 4 and Figure 5As shown, the support plate 100 and the mounting plate 200 are both vertically arranged, the first fixing member 400 is located on the lower side of the support plate 100 and the mounting plate 200 and is connected to the support plate 100, and at least one first adjusting member 500 is screwed to the first fixing member 400 and abuts against the lower side surface of the mounting plate 200.

[0047] For example, Figure 4 and Figure 5 As shown, the first adjusting member 500 includes a first adjusting bolt 510 and a locking nut 520. The first adjusting bolt 510 is threadedly connected to the first fixing member 400 and abuts against the lower side of the mounting plate 200. The first adjusting bolt 510 is rotated to adjust the length of the portion of the first adjusting bolt 510 between the first fixing member 400 and the lower side of the mounting plate 200, so as to adjust the rotation angle of the mounting plate 200 relative to the support plate 100. The locking nut 520 is threadedly connected to the first adjusting bolt 510 and is disposed on a side of the first fixing member 400 away from the mounting plate 200. The first adjusting bolt 510 is locked by the locking nut 520, so that the rotation angle of the mounting plate 200 relative to the support plate 100 remains unchanged.

[0048] The first adjusting member 500 may also be other structures, as long as the first adjusting member 500 can be used to adjust the rotation angle of the mounting plate 200 relative to the support plate 100 . The present disclosure does not specifically limit the structure of the first adjusting member 500 .

[0049] In some embodiments, there are multiple first adjustment members 500, and the multiple first adjustment members 500 are all located on the same side of the mounting plate 200 and are spaced apart from each other to respectively abut different areas of the same side of the mounting plate 200. The multiple first adjustment members 500 are adjusted simultaneously to adjust the rotation angle of the mounting plate 200 relative to the support plate 100, and the adjustment accuracy is high.

[0050] Exemplarily, the two first adjusting members 500 are respectively in contact with the two sides of the lower side of the mounting plate 200. The two first adjusting members 500 can be symmetrically arranged relative to the rotation center of the mounting plate 200 and the support plate 100 to further improve the accuracy of the adjustment.

[0051] In some embodiments, the mounting plate 200 has at least one groove 210, the groove 210 is in an arc shape, the center of the arc is located at the rotation center of the support plate 100, and the support plate 100 has at least one first threaded hole 110. The locking assembly 300 includes: at least one first bolt 310, the first bolt 310 passes through the groove 210 and is screwed to the first threaded hole 110. The above locking method is simple and reliable.

[0052] For example, Figure 6 and Figure 7As shown, the mounting plate 200 has four grooves 210 , and the four grooves 210 are arranged opposite to each other in pairs. The support plate 100 has four first threaded holes 110 , and the locking assembly 300 includes four first bolts 310 .

[0053] In some embodiments, Figure 4 , Figures 6 to 8 As shown, the support plate 100 has a first through hole 120, and the first adjustment assembly 10 further includes a support rod 600, a first connecting member 700 and a second connecting member 800. The support rod 600 has a through slot 610 and a limiting portion 620, the limiting portion 620 extends into the notch of the through slot 610, the first connecting member 700 is disposed in the through slot 610 and can slide in the through slot 610, the first connecting member 700 has a second threaded hole 710, the second connecting member 800 passes through the first through hole 120, and is screwed with the second threaded hole 710 to connect the support plate 100 and the support rod 600. Since the first connecting member 700 can slide in the through slot 610, the support plate 100 can be adjusted along the extension direction of the support rod 600.

[0054] Exemplarily, the support plate 100 has four first through holes 120, wherein two first through holes 120 form a group and are aligned in the vertical direction, and the two groups of first through holes 120 are symmetrically arranged relative to the symmetry axis of the support plate 100. The adjustment assembly 10 also includes a support rod 600, four first connecting members 700 and four second connecting members 800, wherein the support rod 600 has two mutually parallel through grooves 610 and two limit portions 620, and the two first connecting members 700 form a group and are respectively arranged in two mutually parallel through grooves 610 and aligned in the vertical direction, and the two groups of first connecting members 700 are respectively arranged opposite to the two groups of first through holes 120. The above arrangement can improve the stability of the adjustment of the support plate 100 along the extension direction of the support rod 600 and the connection stability between the support plate 100 and the support rod 600.

[0055] The second connecting member 800 may be a bolt, a screw, or other structures with threads. The present disclosure does not specifically limit the structure of the second connecting member 800.

[0056] In some embodiments, the first through hole 120 includes a first long hole 1210, and the extension direction of the first long hole 1210 is perpendicular to the extension direction of the support rod 600. The first long hole 1210 is used to adjust the support rod 600 in the vertical direction.

[0057] In some embodiments, the first adjustment assembly 10 further includes a second fixing member 900 and a second adjustment member 1000, the second fixing member 900 is fixedly connected to the support plate 100, the second fixing member 900 has a third threaded hole 910, the second adjustment member 1000 is threadedly connected to the third threaded hole 910, and abuts against the support rod 600 through the third threaded hole 910. The second adjustment member 1000 is rotated to adjust the length of the portion of the second adjustment member 1000 between the second fixing member 900 and the support rod 600, so as to achieve the adjustment of the support rod 600 in the vertical direction.

[0058] In addition, the first connecting member 700 can slide in the through groove 610, so there is a gap between the first connecting member 700 and the side wall of the through groove 610, and the position of the first connecting member 700 in the through groove 610 can be locked by the second adjusting member 1000, thereby improving the installation stability of the support plate 100. For example, Figure 4 As shown, the second fixing member 900 is fixedly connected to the upper side of the supporting plate 100 .

[0059] The second adjusting member 1000 may include a second adjusting bolt 1001 . The second adjusting bolt 1001 is threadedly connected to the third threaded hole 910 , and passes through the third threaded hole 910 to abut against the upper side surface of the support rod 600 .

[0060] The second adjusting member 1000 may also be other structures with threads, and the present disclosure does not specifically limit the structure of the second adjusting member 1000.

[0061] In some embodiments, the number of the support plate 100, the mounting plate 200 and the locking assembly 300 are all multiple and arranged one by one, and the support plate 100 is arranged linearly along the extension direction of the through slot 610. That is, multiple detection devices 20 are arranged in the extension direction of the support rod 600 to meet the detection requirements.

[0062] In some embodiments, the detection component 1 also includes a second adjustment component 30, which is disposed on the first side of the detection station and connected to the light source component 2, and is configured to adjust the posture of the light source component 2 so that the light emitted by the light source component 2 is emitted to the detection station at an optimal angle, thereby allowing the maximum amount of light to pass through the photovoltaic backplane to project the photovoltaic backplane onto the second side of the detection station.

[0063] The light source assembly 2 has a fourth threaded hole (not shown in the figure). Fig. 9 and Fig.10As shown, the second adjustment assembly 30 also includes: a first direction adjustment plate 1100, a second direction adjustment plate 1200, a third direction adjustment plate 1300 and a fourth direction adjustment plate 1400, a support column 1500, a second bolt 1600, a third bolt 1700 and a fourth bolt 1800. The first direction adjustment plate 1100 is arranged below the support plate 100 and is configured to carry the light source assembly 2. The first direction adjustment plate 1100 has a second long hole 1101. The second direction adjustment plate 1200 is connected to the first direction adjustment plate 1100 and is arranged perpendicular to the first direction adjustment plate 1100.
