Description
Technical Field
[0001] The present application relates to the field of photovoltaic technology, and in particular to an automatic detection device and photovoltaic module assembly equipment. Background Art
[0002] Photovoltaic modules are the core and most important part of solar power generation systems. The function of photovoltaic modules is to convert solar energy into electrical energy and send it to batteries for storage through off-grid systems, or connect to loads or connect to the grid.
[0003] During the production process of photovoltaic modules, the processes are divided into welding, layout, lap welding, lamination, glazing, EL appearance, edge sealing, lamination, edge chamfering, flip inspection, framing, junction box installation, glue filling, curing, cleaning, IV testing, insulation withstand voltage, EL testing, FQC appearance, grading, packaging, etc. After the frame is assembled, it is often found that the frame is scratched during the quality inspection process. The operator cannot judge whether it is due to the defect of the raw material itself or the defect caused by the process. In order to avoid the problem of spending a lot of time to replace the new frame after the frame with poor raw materials is installed incorrectly, the best practice is to perform an appearance inspection on the frame before the framing process.
[0004] In the related art, the frame needs to be flipped to detect different surfaces of the frame. This solution not only has the risk of the frame falling and being damaged, but also, there is a chance that the frame will loosen during the flipping process, which may cause a deviation in the detection environment of the frame, affect the accuracy of the detection structure, and even cause misjudgment of the frame detection result.

[0013] In one embodiment, the positioning mechanism includes a telescopic cylinder and a positioning piece. The telescopic cylinder is installed on the test base platform and is used to drive the positioning piece to perform lifting movements. When the telescopic cylinder drives the positioning piece to rise, the positioning piece protrudes from the table top of the test base platform. The positioning piece and the test base platform jointly form a positioning groove on the peripheral side of the test area for positioning the frame.
[0014] In one embodiment, the first camera assembly includes a first moving mechanism and at least two first cameras, the first cameras are arranged along the height direction of the frame, and the first moving mechanism is used to drive the first cameras to move along the length direction of the frame.

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0034] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.
[0035] The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions are for illustrative purposes only and do not represent the only implementations.
[0036] It should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0037] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0038] See also Figure 1 and Figure 2 As shown, an automatic detection device 10 provided in one embodiment of the present application can automatically detect whether the frame 22 of the photovoltaic module 20 is scratched before assembly, so that the scratched frame 22 can be selected and prohibited from use, avoiding the need to spend time on rework and replacement of the defective frame 22 after assembly, thereby saving time and labor costs.
[0039] For ease of understanding, the structure of the frame 22 is described below in conjunction with the structure of the photovoltaic assembly 20 .
[0040] Combination Figure 2As shown, the photovoltaic module 20 includes a glass component 21 and a frame 22, and the frame 22 surrounds the glass component 21 on all four sides. Among them, the frame 22 corresponding to the long side of the glass component 21 can be called the "long frame 221", and the frame 22 corresponding to the short side of the glass component 21 can be called the "short frame 222". The glass component 21 includes glass 211 and solar cells 212, and the glass 211 covers the solar cells 212 to protect the solar cells 212. In some embodiments, the glass component 21 can be one piece of glass 211 covering multiple solar cells 212, or two pieces of glass 211 can be respectively clamped on the front and back of multiple solar cells 212. For example, the two pieces of glass 211 can be clamped on the front and back of the solar cells 212 by hot pressing. The front side of the solar cell 212 refers to the side facing the sun during use, and correspondingly, the back side of the solar cell 212 refers to the side facing away from the sun during use.
[0041] Combined with Figure 3 and Figure 4 As shown, for the frame 22, the surface of the frame 22 that needs to be inspected for scratches is the appearance surface, such as the side surface 22a and the bottom surface 22b of the frame 22. Based on the appearance, it can be directly seen whether there are scratches. Therefore, in this embodiment, the side surface 22a and the bottom surface 22b of the frame 22 are inspected. The cross-section of the frame 22 is generally L-shaped, so that when the frame 22 is assembled to the edge of the glass component 21, the frame 22 can provide a stepped structure that meets the lap requirements of the glass component 21. In some embodiments, the cross-section of the frame 22 can also be U-shaped. The shape of the frame 22 is not limited here, as long as the frame 22 meets the requirements for assembling and fitting with the edge of the glass component 21.
[0042] Refer to again Figure 1As shown, the automatic detection device 10 includes a test base platform 11, a positioning mechanism 12, a first camera assembly 13 and a second camera assembly 14. The test base platform 11 has a test area for placing a frame 22. The positioning mechanism 12 is connected to the test base platform 11, and the positioning mechanism 12 is used to position the frame 22 in the test area. The first camera assembly 13 is located on the test base platform 11 and is located on the side of the test area. The first camera assembly 13 is used to take a picture of the side 22a of the frame 22 positioned in the test area. The second camera assembly 14 is located below the test base platform 11. The second camera assembly 14 is used to take a picture of the bottom surface 22b of the frame 22 positioned in the test area through the test area. The test base platform 11 is made of transparent material at least at the position corresponding to the test area. Transparent materials include but are not limited to transparent glass or transparent acrylic plates. Of course, the table top of the test base platform 11 can be made of transparent material in its entirety or in part, as long as the position corresponding to the test area is translucent so that the second camera component 14 can take a picture of the bottom surface 22b of the frame 22 positioned in the test area through the test area.
[0043] In the above-mentioned embodiment, the first camera assembly 13 and the second camera assembly 14 can be used to detect the frame 22 placed in the test area to screen out bad frames 22. Moreover, when the automatic detection device 10 is used to detect the frame 22, the positioning mechanism 12 can position the frame in the test area, and the second camera assembly 14 takes a picture of the bottom surface 22b of the frame 22 positioned in the test area through the test area. Therefore, there is no need to flip the frame 22, and the frame 22 can maintain good stability, avoiding the risk of falling of the frame 22 when flipping the frame 22 in the related art, and will not affect the accuracy of the detection result due to the loosening of the frame 22 during the flipping process. Then, the automatic detection device 10 of the present application is adopted to improve the stability of the frame 22 during the detection process, so as to improve the accuracy of the detection result and reduce the probability of misjudgment in the detection of the frame 22.
[0044] The automatic detection device 10 also includes a gripping mechanism (not shown), which is used to grip the frame 22 and transfer the frame 22 to the test base platform 11. In this embodiment, after the frame 22 is transferred to the test base platform 11 by the gripping mechanism, the positioning mechanism 12 positions the frame 22. The gripping mechanism includes but is not limited to a mechanism such as a manipulator, a pneumatic gripper, etc. that can grip the frame 22 and transfer it to the test base platform 11. The structure of the gripping mechanism is not limited here.
[0045] In some embodiments, the positioning mechanism 12 includes a telescopic cylinder 121 and a positioning member 122. The telescopic cylinder 121 is installed on the test base platform 11 and is used to drive the positioning member 122 to perform lifting and lowering movements. When the telescopic cylinder 121 drives the positioning member 122 to rise, the positioning member 122 protrudes from the table of the test base platform 11. In this way, the positioning member 122 and the test base platform 11 together form a positioning groove 123 for positioning the frame 22 on the periphery of the test area. Therefore, when the frame 22 is detected by the automatic detection device 10, the frame 22 is positioned in the test area through the positioning groove 123 to ensure that the frame 22 is placed stably on the test base platform 11. It should be noted that the number of positioning mechanisms 12 is multiple groups, for example, the number of positioning mechanisms 12 is 2 groups or more, so as to position the frame 22 corresponding to different sides of the test area respectively, and improve the positioning effect.
[0046] In some embodiments, when the frame 22 is inspected by the automatic inspection device 10, the frame 22 is transferred to the test base platform 11 by the gripping mechanism, and after the frame 22 is positioned by the positioning mechanism 12, the positioning mechanism 12 is withdrawn from the table of the test base platform 11. For example, in an embodiment in which the positioning mechanism 12 includes a telescopic cylinder 121 and a positioning member 122, when it is necessary to position the frame 22, the telescopic cylinder 121 is lifted so that the positioning member 122 protrudes from the table of the test base platform 11 to position the frame 22. After the positioning of the frame 22 is completed, the telescopic cylinder 121 retracts downward, so that the positioning member 122 moves downward relative to the test base platform 11, so that the positioning member 122 does not protrude from the table of the test base platform 11, thereby leaving detection space for the first camera assembly 13, and preventing the positioning member 122 from blocking the camera assembly 13's line of sight when taking pictures of the side 22a of the frame 22, so as to ensure the accuracy of scratch detection.
[0047] Combination Figure 1 and Figure 6 As shown, the first camera assembly 13 includes a first moving mechanism 131 and at least two first cameras 132. It should be noted that at least two first cameras 132 means that the number of the first cameras 132 can be two or more than two. For example, when the frame 22 is positioned in the test area, two or more first cameras 132 are opposite to the side 22a of the frame 22 to shoot the side 22a of the frame 22. In this embodiment, the first moving mechanism 131 is used to drive the first camera 132 to move along the length direction of the frame 22, so that the first camera 132 can scan the side 22a of the frame 22 to fully detect the appearance defects of the side 22a of the frame 22.
[0048] The first cameras 132 may be arranged in a vertical direction, that is, the first cameras 132 are arranged in a height direction of the frame 22. Thus, when the first moving mechanism 131 drives the first cameras 132 to move, the first cameras 132 may move synchronously in a length direction of the frame 22 to improve the detection accuracy of the side surface 22a of the frame 22. The number of the first cameras 132 is not limited herein.
[0049] Continue to combine Figure 1 and Figure 6 As shown, the second camera assembly 14 includes a second moving mechanism 141 and at least two second cameras 142. It should be noted that at least two second cameras 142 means that the number of second cameras 142 can be two or more than two. For example, when the frame 22 is positioned in the test area, two or more second cameras 142 are opposite to the bottom surface 22b of the frame 22 to shoot the bottom surface 22b of the frame 22. In this embodiment, the second moving mechanism 141 is used to drive the second camera 142 to move along the length direction of the frame 22, so that the second camera 142 can scan the bottom surface 22b of the frame 22 to comprehensively detect the appearance defects of the bottom surface 22b of the frame 22.
[0050] The second cameras 142 are arranged in the horizontal direction. For example, the second cameras 142 are arranged in the width direction of the frame 22, so that when the second moving mechanism 141 drives the second cameras 142 to move, the second cameras 142 can move synchronously along the length direction of the frame 22 to improve the detection accuracy of the bottom surface 22b of the frame 22.
[0051] The structures of the first moving mechanism 131 and the second moving mechanism 141 may be the same or different. The first moving mechanism 131 and the second moving mechanism 141 may be belt mechanisms or chain mechanisms.
[0052] For example, in some embodiments, the first moving mechanism 131 includes a first moving chain and a first mounting seat. The first camera 132 is mounted on the first mounting seat, and the first moving chain is connected to the first mounting seat and used to drive the first mounting seat to move, so that the first mounting seat moves together with the first camera 132 to scan the side 22a of the frame 22. Correspondingly, the second moving mechanism 141 includes a second moving chain and a second mounting seat. The second camera 142 is mounted on the second mounting seat, and the second moving chain is connected to the second mounting seat and used to drive the second mounting seat to move, so that the second mounting seat moves together with the second camera 142 to scan the bottom surface 22b of the frame 22.
[0053] The automatic detection device 10 also includes an image analysis and judgment module, and the first camera assembly 13 and the second camera assembly 14 are both connected to the image analysis and judgment module by signal. The image analysis and judgment module is used to judge whether the frame 22 is a good product based on the images captured by the first camera assembly 13 and the second camera assembly 14. For example, after receiving the images of the side surface 22a and the bottom surface 22b of the frame 22 captured by the first camera assembly 13 and the second camera assembly 14, the image analysis and judgment module compares the images with the pre-set images of the good frame 22, and can judge whether the frame 22 is a good product.
[0054] It should be noted that in the embodiment where the first camera assembly 13 includes the first moving mechanism 131, the first moving mechanism 131 can drive the first camera 132 to move along the length direction of the frame 22 to scan the side 22a of the frame 22. Therefore, when the first camera 132 stays at different positions in the length direction of the frame 22, the current position can be imaged. In this way, the movement of the first camera 132 by the first moving mechanism 131 can realize segmented shooting of all parts of the side 22a of the frame 22. Based on this, when the image analysis and judgment module performs image comparison, the image of the corresponding position of the frame 22 of the current object can be compared with the image of a corresponding position of the frame 22 of the good product (which can be pre-set in the database of the computer). When the image of a certain position of the frame 22 captured shows a significant difference from the image of the corresponding position in the database, it is determined to be a defective product.
[0055] Accordingly, in the embodiment where the second camera assembly 14 includes the second moving mechanism 141, the second moving mechanism 141 can drive the second camera 142 to move along the length direction of the frame 22 to scan the bottom surface 22b of the frame 22. Therefore, when the second camera 142 stays at different positions in the length direction of the frame 22, the current position can be imaged. In this way, the movement of the second camera 142 by the second moving mechanism 141 can realize the segmented shooting of all parts of the bottom surface 22b of the frame 22. Based on this, when the image analysis and judgment module performs image comparison, the image of the corresponding position of the frame 22 of the real object currently photographed can be compared with the image of a corresponding position of the frame 22 of the good product (which can be pre-set in the database of the computer). When the image of a certain position of the frame 22 photographed shows a significant difference with the image of the corresponding position in the database, it is judged as a defective product.
[0056] In some embodiments, the gripping mechanism is electrically connected to the image analysis and judgment module, and the gripping mechanism is also used to sort good and bad frames 22 according to the judgment result of the image analysis and judgment module. In this embodiment, the gripping mechanism is used to sort good and bad frames 22, and bad frames 22 are removed, thereby avoiding the use of bad products and causing subsequent rework, reducing the loss of other auxiliary materials caused by replacing the frame 22, and thus reducing production costs.
[0057] The image analysis and judgment module may be integrated on the mainboard of the computer to utilize the data analysis capability of the computer to complete the image analysis and then judge whether the appearance of the side surface 22a and the bottom surface 22b of the frame 22 is normal.
[0058] The computer can be connected to a display screen 101 (see Figure 5 As shown in FIG. 1 ), the display screen 101 may be provided with two or more display areas 1011, wherein one display area 1011 is used to display the image of the good-quality frame 22, and the other display area 1011 is used to display the measured real-object image obtained by the first camera assembly 13 and the second camera assembly 14. When the image analysis and judgment module is used to judge whether the frame 22 is a good-quality product, the operator can also visually observe the appearance of the frame 22 from the display screen 101.
[0059] The number of display areas 1011 on the display screen 101 can be set according to actual needs and is not limited here. Figure 5 As shown, the display screen 101 provides two display areas 1011. Figure 5 The left display area 1011 can display the image of the frame 22 of a good product, and the right display area 1011 can display the measured real object image. Of course, in some embodiments, the position of the display area 1011 displaying the image of the frame 22 of a good product can be interchanged with the position of the display area 1011 displaying the measured real object image.
[0060] Combination Figure 7 As shown, the test base platform 11 is provided with a good product inventory area 102 . When the image analysis and judgment module determines that the frame 22 is a good product, the good frame 22 can be centrally stored in the good product inventory area 102 for subsequent photovoltaic assembly 20 use.
[0061] In some embodiments, when the image analysis and judgment module determines that the frame 22 is a good product, the gripping mechanism places the frame 22 in the good product inventory area 102. The good product inventory area 102 can be divided into a first area 1021 and a second area 1022, and the first area 1021 and the second area 1022 are used to store the long frame 221 and the short frame 222 of the good product respectively. It should be noted here that both the long frame 221 and the short frame 222 can be detected by the above-mentioned automatic detection device 10 to see if there are scratches.
[0062] The good product inventory area 102 is provided with a transmission mechanism to transport the frames 22 of good products to subsequent workstations.
[0063] Combine again Figure 1 and Figure 3 As shown, in some embodiments, the frame 22 also has an inner surface 22c opposite to the side surface 22a. The automatic detection device 10 also includes a third camera assembly, which is used to take a picture of the inner surface 22c of the frame 22 to determine whether the inner surface 22c of the frame 22 is scratched or damaged. It should be noted that the third camera assembly includes a third camera 15, and the number of the third cameras 15 can be 1, or 2 or more, which is not limited here.
[0064] It should be noted that the frames 22 of qualified products detected by the automatic detection device 10 can be stored and transferred to other production lines by a handling robot for subsequent assembly. In some embodiments, the automatic detection device 10 can also be used as one of the devices in the photovoltaic module assembly process. After being detected by the automatic detection device 10, the frames 22 of qualified products flow into the subsequent stations for assembly. For example, in combination with Figure 8 As shown, the present application also provides a photovoltaic module assembly device 100 including the above-mentioned automatic detection device 10. The automatic detection device 10 is used as a device in the photovoltaic module assembly device 100, so that the photovoltaic module assembly device 100 has the function of performing appearance detection on the frame 22. The photovoltaic module assembly device 100 also includes a fixing component 110 and a clamping mechanism 120. Among them, the fixing component 110 is used to fix the glass component 21, and the clamping mechanism 120 is used to assemble the frame 22 of the qualified product detected by the automatic detection device 10 to the four sides of the glass component 21. The clamping mechanism 120 includes but is not limited to a mechanism such as a manipulator, a pneumatic clamp, etc. that can realize grabbing the frame 22 and assembling the frame to the glass component 21.
[0065] In some embodiments, four clamping mechanisms 120 are respectively disposed around the fixing assembly 110 to respectively assemble the frame 22 on the four sides of the glass assembly 21 supported by the fixing assembly 110. In some embodiments, the number of the clamping mechanisms 120 may be 1, 2 or 3, which is not limited here.
[0066] In an embodiment where a transmission mechanism is provided in the good product inventory area 102, the clamping mechanism 120 is used to grab the frame 22 transmitted by the transmission mechanism and assemble the frame 22 to the corresponding side of the glass assembly 21, that is, the long frame 221 is assembled to the long side of the glass assembly 21, and the short frame 222 is assembled to the short side of the glass assembly 21. The transmission mechanism includes but is not limited to a belt transmission mechanism or a chain transmission mechanism.
[0067] Combination Figure 8 and Fig. 9 As shown, the fixing assembly 110 includes a suction cup 111 and a support. The suction cup 111 is arranged on the support, and the glass assembly 21 is adsorbed by the suction cup 111, so that the glass assembly 21 is supported on the support, so that the four sides of the glass assembly 21 are suspended in the air, which is conducive to assembling the frame 22 to the four sides of the glass assembly 21. It should be noted that the length of the long frame 221 is greater than the length of the short frame 222, and the length of the long frame 221 is adapted to the length of the glass assembly 21, and the length of the short frame 222 is adapted to the width of the glass assembly 21, so that when the long frame 221 is assembled on the long side of the glass assembly 21 and the short frame 222 is assembled on the short side of the glass assembly 21, the edge of the photovoltaic assembly 20 can be neat.
