Description

Technical Field

[0001] This application relates to the field of photovoltaic module packaging technology, and in particular to an automatic capping device and a photovoltaic module packaging system. Background Technology

[0002] Photovoltaic modules, also known as solar cell modules or solar panels, are the core and most important component of a solar power generation system. Their function is to convert solar energy into electrical energy, which is then either stored in batteries or used to power loads. During the production of photovoltaic modules, the finished modules need to be stacked and packaged for transport. Currently, the industry commonly uses nested cardboard boxes for packaging. The specific process is as follows: first, the bottom box is unfolded and fitted onto the outside of the stacked modules, and then the top cover is installed on top of the bottom box to complete the sealing. However, because the size of multiple photovoltaic modules stacked together is very large, the size of the top cover used for packaging is correspondingly large. Generally, multiple people work together to install the top cover before strapping it on. However, manually installing the top cover requires bending it before it can be installed on the photovoltaic modules, resulting in low work efficiency, a very large amount of manual labor, and high labor costs.

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0047] After photovoltaic modules are manufactured, they need to be packaged for subsequent transportation. Because of their flat shape, they are usually stacked in piles before packaging. The packaging process is complex, involving stacking, inner strapping, corner protector installation, cardboard box packaging, outer strapping, and wrapping, among other steps. It involves multiple workstations and is often designed as an assembly line.

[0048] Current packaging lines employ both manual and semi-automatic methods. Taking the carton-packing process as an example, the industry commonly uses interlocking cartons. The specific procedure involves unfolding the bottom box and fitting it around the stacked modules, then installing the top cover on top of the bottom box to complete the sealing. However, due to the very large size of multiple stacked photovoltaic modules, the size of the top cover used for packaging is correspondingly large. Typically, multiple people work together to install the top cover before strapping and packaging. However, manually installing the top cover requires bending it before it can be installed on the photovoltaic modules, resulting in low efficiency, a large workload, and high labor costs.

[0049] In response, one embodiment of this application provides an automatic capping device for capping and packaging photovoltaic modules on a packaging line 40. The packaging line 40 can be narrowly defined as a conveyor belt, which transports photovoltaic modules to different workstations, such as... Figure 1 As shown, the packaging line 40 has a material placement area A and a straightening area B on its side, and a bottom box expansion area C on its top.

[0050] like Figure 2As shown, the automatic capping device 10 includes a gripping module 100, a straightening module 200, and an expanding module 300. The gripping module 100 can transfer the top cap 20 from the material placement area A to the straightening area B. The straightening module 200 can straighten the top cap 20 in the straightening area B, and the gripping module 100 can also transfer the straightened top cap 20 from the straightening area B to the bottom box expanding area C, and perform a pressing operation on the top cap 20 during the transfer. The expanding module 300 can expand the bottom box 30 in the bottom box expanding area C, and the gripping module 100 can also place the pressed top cap 20 into the expanded bottom box 30. Figure 12 The structure of the top cover 20 after the short side is pressed is shown.

[0051] After the photovoltaic modules are encased and conveyed to the capping station by the conveyor belt, the gripping module 100 of the automatic capping device 10 transfers the top cap 20 from the material placement area A to the alignment area B. The alignment module 200 then aligns the top cap 20 in the alignment area B. Afterward, the gripping module 100 transfers the aligned top cap 20 from the alignment area B to the bottom box expansion area C, performing an edge-pressing operation on the top cap 20 during the transfer. Simultaneously, the expansion module 300 expands the bottom box 30 on the conveyor belt 1142c in the bottom box expansion area C. After the bottom box 30 has been expanded, the gripping module 100 places the edge-pressed top cap 20 into the bottom box 30, thus completing the capping of the photovoltaic modules. Therefore, the automatic capping device 10 provided in this application, through the cooperation of the gripping module 100, the alignment module 200, and the expansion module 300, can achieve automatic capping of photovoltaic modules, which not only improves packaging efficiency but also reduces labor costs.

[0052] In some embodiments of this application, such as Figure 2 As shown, the gripping module 100 includes a transport robot 120 and a gripping body 110; further, as Figure 3 and Figure 4 As shown, the gripping body 110 includes a frame assembly 111, a first suction cup assembly 112, and a bending assembly 113. The frame assembly 111 is located at the execution end of the handling robot 120, and the length of the frame assembly 111 is adjustable. The first suction cup assembly 112 is located at least at both ends of the frame assembly 111 along its length. The bending assembly 113 is located at the end of the frame assembly 111 along its length and is capable of bending the edge of the top cover 20. Throughout this text, the terms "length direction," "width direction," and "thickness direction" of the frame assembly 111 are used to refer to... Figure 3 The information shown shall prevail.

[0053] After the photovoltaic modules are encased and transported to the capping station by conveyor belt 1142c, the gripping module 100's gripping body 110 first adjusts the length of the frame component 111 according to the size of the top cover 20, and then grips the top cover 20 by adsorption through the first suction cup component 112. Next, the transport robot 120 transports the top cover 20 to the alignment zone B. After the top cover 20 is aligned, the transport robot 120 transports the top cover 20 again to the bottom box expansion zone C. During the transport process, the bending component 113 bends the edge of the top cover 20 (e.g., the short or long side). After the bottom box 30 completes the expansion operation, the transport robot 120 lowers the top cover 20 and places the edge-pressed top cover 20 into the expanded bottom box 30. It can be seen that the gripping module 100 with this structure facilitates the transfer of the top cover 20 and can grip top covers 20 of different sizes, enabling capping operations on photovoltaic modules of different specifications, thereby expanding the application range of the automatic capping device 10.

[0054] The handling robot 120 can be a six-joint robot with a maximum working radius of 2000mm to 3000mm, a repeatability of ±0.10mm, a six-joint movement speed of 200° / s to 600° / s, and a weight of 200±20KG. It can handle high loads of less than 100KG and can meet the handling requirements of the top cover 20. In addition, the robotic arm of the handling robot 120 can handle a distance of 3000mm after it is extended, which makes it easy for the first suction cup assembly 112 at the front end of the robot to pick up the top cover 20 and carry it to the top of the bottom box 30 on the packaging line 40.

[0055] In one embodiment, such as Figures 3 to 4 As shown, the frame assembly 111 includes a main frame 1111 and a sub-frame 1112. The main frame 1111 is mounted on the handling robot 120, and the sub-frame 1112 is located at the end of the main frame 1111 along its length and can move along the length of the main frame 1111. A bending assembly 113 is located at the end of the sub-frame 1112 away from the main frame 1111. The first suction cup assembly 112 includes multiple first suction cups 1121 and multiple second suction cups 1122. The first suction cups 1121 are located on the main frame 1111, and the second suction cups 1122 are located at the end of the sub-frame 1112 away from the main frame 1111. The main frame 1111 and the sub-frame 1112 are respectively provided with first suction cups 1121 and second suction cups 1122, enabling the gripping module 100 to effectively adsorb top covers 20 of different sizes.

[0056] The dimensions of the main frame 1111 can be set according to the dimensions of the top cover 20, for example, the length can be set to approximately 1500mm and the width to 900mm-1100mm. It can be a rectangular frame made of connected profiles, where the cross-sectional dimensions of the profiles can be set according to requirements. For example, the profiles used for the edge of the main frame 1111 can have a cross-sectional dimension of 80mm × 40mm, while the profiles used for the middle part of the main frame 1111 can have a cross-sectional dimension of 40mm × 40mm. For example... Figure 3 As shown, the main frame 1111 has a mounting bracket 1113 in the middle. The mounting bracket 1113 can be installed on the execution end of the handling robot 120 by means of screw connection, snap connection or other methods.

[0057] The sub-frame 1112 can also be formed by connecting profiles, wherein the sub-frame 1112 can be one or more. Figure 3 and Figure 4 The two shown are subframes 1112, which are respectively set at the two ends of the main frame 1111 along the length direction.

[0058] The number of first suction cups 1121 can be set according to requirements. For example, two first suction cups 1121 can be set on each of the two frame sides along the length of the main frame 1111, and two first suction cups 1121 can be set in the middle of the main frame 1111. In order to improve the adsorption effect on the top cover 20, a reinforcing frame 1114 can be provided at each end of the two frame sides along the length of the main frame 1111 (see...). Figure 5 The reinforcing frame 1114 is equipped with a first suction cup 1121. The number of second suction cups 1122 can be set according to the requirements. For example, four second suction cups 1122 can be set at intervals on the sub-frame 1112 along the width direction of the main frame 1111.

[0059] In one embodiment, the automatic capping device 10 further includes a vacuum module (not shown in the drawings). The vacuum module is connected to the first suction cup 1121 and the second suction cup 1122. When the first suction cup 1121 and the second suction cup 1122 adsorb the top cover 20, the vacuum module evacuates the first suction cup 1121 and the second suction cup 1122. The pressure difference under vacuum conditions allows the top cover 20 to be adsorbed onto the first suction cup 1121 and the second suction cup 1122. When the first suction cup 1121 and the second suction cup 1122 release the top cover 20, the vacuuming of the first suction cup 1121 and the second suction cup 1122 stops. The vacuum module may include a vacuum pump.

[0060] In one embodiment, such as Figure 5As shown, the gripping module 100 also includes a first drive module 114, which drives the sub-frame 1112 to move along the length of the main frame 1111. The first drive module 114 includes a first power component 1141, a first belt drive mechanism 1142, and a first lead screw drive mechanism 1143. The first power component 1141 is mounted on the main frame 1111. The first belt drive mechanism 1142 is connected between the first power component 1141 and the first lead screw drive mechanism 1143. The first lead screw drive mechanism 1143 is connected to both the main frame 1111 and the sub-frame 1112. The transmission directions of the first lead screw drive mechanism 1143 and the first belt drive mechanism 1142 are perpendicular. The transmission direction of the first belt drive mechanism 1142 is the width direction of the frame assembly 111, and the transmission direction of the first lead screw drive mechanism 1143 is the length direction of the frame assembly 111. This first drive module 114 has a compact structure and is easy to install. Of course, in some other embodiments, the transmission mechanism of the first drive module 114 may only include the first belt drive mechanism 1142 or the first lead screw drive mechanism 1143, or other types of transmission mechanisms. The number of first drive modules 114 may be the same as that of the sub-frame 1112, both being set to 2, with one first drive module 114 driving one sub-frame 1112 to move.

[0061] The first power component 1141 can be a rotary motor, and the housing of the rotary motor can be installed in the middle of the main frame 1111.

[0062] like Figure 5 As shown, the first belt drive mechanism 1142 may include a drive pulley 1142a, a driven pulley 1142b, and a conveyor belt 1142c. The drive pulley 1142a is located on the output shaft of the first power member 1141, the driven pulley 1142b is located on the power input end of the first lead screw drive mechanism 1143, and the conveyor belt 1142c is located on the drive pulley 1142a and the driven pulley 1142b.

[0063] like Figure 5As shown, the first lead screw transmission mechanism 1143 may include a lead screw 1143a, a lead screw nut 1143b, a first support seat 1143c, and a second support seat 1143d; the first support seat 1143c and the second support seat 1143d are spaced apart along the length of the main frame 1111 in the middle of the main frame 1111; the lead screw 1143a is rotatably mounted on the first support seat 1143c and the second support seat 1143d and connected to the driven pulley 1142b of the first belt transmission mechanism 1142; the lead screw nut 1143b is sleeved on the lead screw 1143a and connected to the sub-frame 1112. When the output shaft of the first power component 1141 rotates, the driving wheel 1142a of the first belt drive mechanism 1142 drives the driven wheel 1142b to rotate through the conveyor belt 1142c. The lead screw 1143a rotates together with the driven wheel 1142b, and the lead screw nut 1143b moves along the length of the main frame 1111 with the secondary frame 1112 when the lead screw 1143a rotates.

[0064] In one embodiment, such as Figure 5 and Figure 6 As shown, the bending assembly 113 includes a mounting base 1131, a bending cylinder 1132, a connecting shaft 1133, and a folding member 1134. The mounting base 1131 is located at the end of the frame assembly 111 along its length and is movable along the thickness of the frame assembly 111. The bending cylinder 1132 is mounted on the mounting base 1131. The connecting shaft 1133 is rotatably connected to the bending cylinder 1132 and the mounting base 1131. The folding member 1134 is rotatably connected to the connecting shaft 1133. When the piston rod of the bending cylinder 1132 extends or retracts, the connecting shaft 1133 can drive the folding member 1134 to rotate. When the handling robot 120 moves the top cover 20 from the alignment zone B to the bottom box expansion zone C, the mounting base 1131 moves toward the top cover 20 along the thickness direction of the frame assembly 111. After the folding part 1134 contacts the top cover 20, the bending cylinder 1132 pushes the connecting shaft 1133 to rotate, and the folding part 1134 bends the short or long side of the top cover 20.

[0065] The number of bending components 113 is the same as that of the sub-frame 1112, and can be set to 2. These 2 bending components 113 are set on the ends of the corresponding sub-frame 1112 in the length direction.

[0066] Folding component 1134 can be Figure 5 The strip plate shown may have push protrusions 1134a at both ends along the width direction of the frame assembly 111. The push protrusions 1134a facilitate the folding member 1134 to press against the top cover 20, which is beneficial for pressing the edge of the top cover 20. Optionally, two bending cylinders 1132 and two connecting shafts 1133 may be provided respectively. Each end of the folding member 1134 along the width direction of the frame assembly 111 is provided with a bending cylinder 1132 and a connecting shaft 1133.

[0067] The coupling 1133 can be a cam structure. The coupling 1133 has three rotation points, which are rotatably connected to the mounting base 1131, the bending cylinder 1132 and the folding part 1134, respectively.

[0068] Furthermore, in one embodiment, as Figure 5 and Figure 6 As shown, the bending assembly 113 also includes an adjusting cylinder 1135, which is mounted on the sub-frame 1112 and connected to the mounting base 1131. The adjusting cylinder 1135 can drive the mounting base 1131 to move along the thickness direction of the frame assembly 111. The number of adjusting cylinders 1135 is the same as the number of sub-frames 1112, with one adjusting cylinder 1135 mounted on each sub-frame 1112.

[0069] In one embodiment, such as Figure 3 As shown, the gripping module 100 also includes a first cable chain mechanism 130, which is located at the movable connection between the main frame 1111 and the sub-frame 1112. The first cable chain mechanism 130 is used to carry electrical wires, thus preventing damage to the wires.

[0070] The alignment module 200 is mainly used to align the position of the top cover 20, so that when the gripping module 100 moves the top cover 20, it can press down the short or long side of the top cover 20, and can move the top cover 20 directly above the bottom box 30, facilitating the sealing of the top cover 20. In one embodiment, such as Figure 7 and Figure 8 As shown, the correction module 200 includes a correction frame 210, a plurality of first correction blocks 220, and a plurality of second correction blocks 230. A correction platform 211 is provided at the top of the correction frame 210. The plurality of first correction blocks 220 are located on both sides of the correction platform 211 along its length. The plurality of second correction blocks 230 are located on both sides of the correction platform 211 along its width and, together with the first correction blocks 220, form a correction zone B. At least one of the first correction blocks 220 is movable along the length of the correction platform 211, and at least one of the second correction blocks 230 is movable along the width of the correction platform 211. Throughout the text, the "length direction" and "width direction" of the correction module 200 are referred to as... Figure 7 and Figure 8 As shown in the figure. After the handling robot 120 of the gripping module 100 transfers the top cover 20 to the alignment platform 211 of the alignment module 200, the first suction cup assembly 112 of the gripping module 100 releases the top cover 20; then, the first alignment block 220 on at least one side and the second alignment block 230 on at least one side of the alignment platform 211 begin to move until the alignment of the top cover 20 is completed.

[0071] like Figure 8As shown, the first correction block 220 may include a movable strip 221 and at least one correction ear plate 222. The movable strip 221 is movably disposed on the correction frame 210 and located below the correction platform 211. The correction platform 211 has a first blind hole 211a, and the correction ear plate 222 passes through the first blind hole 211a from the correction platform 211. The number of correction ear plates 222 may be one, and this one correction ear plate 222 is disposed in the middle of the movable strip 221; of course, as... Figure 8 As shown, there can also be two straightening ear plates 222, which are located at the two ends of the moving strip 221 along the width direction of the straightening frame 210. The second straightening stop 230 can have the same structure as the first straightening stop 220.

[0072] As an example, the first correction blocks 220 on both sides of the correction platform 211 can move along the length direction of the correction platform 211, and the second correction blocks 230 on one side of the correction platform 211 can move along the width direction of the correction platform 211.

[0073] Furthermore, in one embodiment, as Figure 8 As shown, the correction module 200 also includes a second drive assembly 240. The second drive assembly 240 can drive the movement of at least one of the first correction blocks 220 and includes a second power component 241 and a second belt drive mechanism 242. The second power component 241 is disposed on the correction frame 210 and connected to the second belt drive mechanism 242. The second belt drive mechanism 242 is connected to at least one of the first correction blocks 220. The second power component 241 has the same structure as the first power component 1141, and the second belt drive mechanism 242 has the same structure as the first belt drive mechanism 1142. When the first correction blocks 220 on both sides of the correction platform 211 move along the length direction of the correction platform 211, the first correction blocks 220 on both sides can share the belt of the second belt drive mechanism 242. One side of the first correction block 220 is connected to the upper half of the belt of the second belt drive mechanism 242, and the other side of the first correction block 220 is connected to the lower half of the belt of the second belt drive mechanism 242.

[0074] The alignment frame 210 is provided with a first alignment guide rail 212, which is located below the alignment platform 211 and extends along the length of the alignment frame 210. A first alignment stop 220 can move along the first alignment guide rail 212. The number of first alignment guide rails 212 is the same as the number of movable first alignment stops 220. When both first alignment stops 220 on both sides of the alignment platform 211 can move along the length of the alignment frame 210, a first alignment guide rail 212 is provided on each side of the alignment frame 210's length.

[0075] See also Figure 8In one embodiment, the correction module 200 further includes a third drive component 250, which is capable of driving at least one side of the second correction block 230 to move, and includes a correction cylinder connected to the correction frame 210 and at least one side of the second correction block 230. The correction cylinder can drive the second correction block 230 to move along the width direction of the correction frame 210. The number of correction cylinders is the same as the number of movable second correction blocks 230. When both sides of the correction frame 210 can move, two correction cylinders are correspondingly provided, each driving one second correction block 230 to move. The third drive component 250 and the second drive component 240 can have the same structure or be interchanged.

[0076] The correction frame 210 is provided with a second correction guide rail 213 (see Figure 8 The second correction guide rail 213 is located below the correction platform 211 and extends along the width direction of the correction frame 210. The second correction block 230 can move along the second correction guide rail 213. The number of second correction guide rails 213 is the same as the number of movable second correction blocks 230. When the second correction blocks 230 on both sides of the correction platform 211 can move along the width direction of the correction frame 210, there is a second correction guide rail 213 on each side of the width direction of the correction frame 210.

[0077] The expansion module 300 is mainly used to enlarge the opening of the base box 30, creating a gap between the inner wall of the base box 30 and the outer wall of the photovoltaic module, facilitating the placement of the top cover 20 within this gap. Figure 9As shown, in one embodiment, the expansion module 300 includes a support component 310, an expansion frame 320, a second suction cup component 330, and a disengaging component 340; the expansion frame 320 is movably mounted on the support component 310; the second suction cup component 330 is mounted on the expansion frame 320 and can pull the bottom box 30 outward along the length or width direction of the expansion frame 320; the disengaging component 340 is mounted on the expansion frame 320 and can extend into the bottom box 30 and move along the length or width direction of the expansion frame 320 to enlarge the opening of the bottom box 30. When it is necessary to expand the bottom box 30, the second suction cup assembly 330 is first used to pull the bottom box 30 outward, creating a certain gap between the inner wall of the bottom box 30 and the outer wall of the photovoltaic module. Then, the prying assembly 340 is inserted into the opening of the bottom box 30 and moves along the length or width direction of the expansion frame 320, further increasing the gap between the inner wall of the bottom box 30 and the outer wall of the photovoltaic module, thus widening the opening of the bottom box 30. Afterward, the handling robot 120 lowers the top cover 20 into the gap between the inner wall of the bottom box 30 and the outer wall of the photovoltaic module. Pulling the bottom box 30 outward with the second suction cup assembly 330 before inserting the prying assembly 340 into the bottom box 30 avoids damaging the photovoltaic module and the box wall of the bottom box 30. The "length direction" and "width direction" of the expansion frame 320 in the entire text refer to... Figure 9 The information shown shall prevail.

[0078] If the short side of the top cover 20 is bent, the second suction cup assembly 330 can move along the length direction of the expanding frame 320, and the push-open assembly 340 can also move at least along the length direction of the expanding frame 320; if the long side of the top cover 20 is bent, the second suction cup assembly 330 can move along the width direction of the expanding frame 320, and the push-open assembly 340 can also move at least along the width direction of the expanding frame 320.

[0079] like Figure 9 As shown, the support assembly 310 may include a support frame 311 and a lifting unit 312. The lifting unit 312 may include a fifth power component 3121 and a fifth belt drive mechanism 3122. The fifth power component 3121 is mounted on the support frame 311 and connected to the fifth belt drive mechanism 3122. The structure of the fifth belt drive mechanism 3122 is the same as that of the first belt drive mechanism 1142. The belt of the fifth belt drive mechanism 3122 is connected to the expanding frame 320.

[0080] The expanded frame 320 can be a quadrilateral frame, which can be made of profiles connected together.

[0081] The second suction cup assembly 330 includes a plurality of third suction cups 331 (see...) Figure 10 Multiple third suction cups 331 are disposed on both sides of the expansion frame 320 in the length or width direction, wherein each third suction cup 331 is connected to the vacuum module.

[0082] Furthermore, in one embodiment, as Figure 10 As shown, the disengaging assembly 340 may include a disengaging seat 341, a disengaging rod 342, a fixing seat 343, and a disengaging cylinder (not shown in the figure); the fixing seat 343 is disposed on the expanding frame 320 and can move along the length or width direction of the expanding frame 320; the disengaging cylinder is disposed on the fixing seat 343 and can drive the disengaging seat 341 to move up and down; the disengaging rod 342 is disposed on the side of the disengaging seat 341 away from the fixing seat 343.

[0083] The lever 342 can be an "L" shaped lever (see...) Figure 10 ), among which, such as Figure 10 As shown, the side of the push-opening seat 341 away from the fixed seat 343 is provided on the auxiliary rod 3411. The auxiliary rod 3411 is connected to the push-opening rod 342. The auxiliary rod 3411 can be an inverted "L" shaped rod, wherein the upper oblique part of the auxiliary rod 3411 is connected to the horizontal part of the push-opening rod 342.

[0084] The number of the opening components 340 can be set to four. Two opening components 340 are provided on each side of the length direction of the expansion frame 320, and the two opening components 340 on each side are located at the end of the width direction of the expansion frame 320.

[0085] like Figure 11 As shown, in one embodiment, the expansion module 300 further includes a fourth drive module 350. The fourth drive module 350 is capable of driving the disengaging component 340 to move along the length direction of the expansion frame 320, and includes a third power component 351, a bevel gear transmission mechanism 352, and a third belt transmission mechanism 353. The third power component 351 is disposed on the expansion frame 320 and connected to the bevel gear transmission mechanism 352, and the third belt transmission mechanism 353 is connected to the bevel gear transmission mechanism 352 and the disengaging component 340. This arrangement of the fourth drive module 350 makes the structure of the expansion module 300 more compact.

[0086] The third power component 351 can be a rotary motor, which can be mounted on the end of the expanded frame 320 along its length via a connecting seat 321 (see [link]). Figure 11 ).

[0087] The bevel gear transmission mechanism 352 may include a first bevel gear, a second bevel gear, and a transmission shaft. The first and second bevel gears are rotatably mounted in the connecting seat 321. The first bevel gear is mounted on the output shaft of the third power member 351 and meshes with the second bevel gear. The second bevel gear is mounted on the transmission shaft, which is connected to the third belt transmission mechanism 353. The third belt transmission mechanism 353 may have the same structure as the first belt transmission mechanism 1142. When the disengaging component 340 needs to move along the length of the expanding frame 320, the output shaft of the third power member 351 rotates, and the transmission shaft also rotates through the transmission between the first and second bevel gears, thereby driving the belt of the third belt transmission mechanism 353 to move, and the disengaging component 340 moves along the length of the expanding frame 320.

[0088] like Figure 11 As shown, a first expansion guide rail 323 is provided on one side of the expansion frame 320 in the width direction. The first expansion guide rail 323 extends along the length direction of the expansion frame 320 and is located above the lower half of the belt of the third belt drive mechanism 353. The disengaging component 340 can move along the first expansion guide rail 323. The disengaging component 340 is connected to the upper half of the belt of the third belt drive mechanism 353 through a fixing frame 322. As an example, the second suction cup component 330 is also provided on the fixing frame 322. This arrangement allows the second suction cup component 330 and the disengaging component 340 to share the fourth drive module 350, thus simplifying the structure of the device.

[0089] When both sides of the expansion frame 320 are provided with a dispersing component 340, two fourth drive modules 350 are also provided accordingly. The third power component 351 and the bevel gear transmission mechanism 352 of the two fourth drive modules 350 are located on both sides of the expansion frame 320 in the length direction, and the third belt transmission mechanism 353 of the two fourth drive modules 350 are located on both sides of the expansion frame 320 in the width direction. The belt transmission directions of the two fourth drive modules 350 are opposite, so that the dispersing components 340 on both sides of the expansion frame 320 in the length direction move towards each other or in opposite directions.

[0090] like Figure 11As shown, in one embodiment, the expansion module 300 further includes a fifth drive module 360. The fifth drive module 360 ​​can drive the disengaging component 340 to move along the width direction of the expansion frame 320, and includes a fourth power member 361 and a fourth belt drive mechanism 362. The fourth power member 361 is mounted on a fixing frame 322 on the expansion frame 320 and is connected to the fourth belt drive mechanism 362. The fourth belt drive mechanism 362 is connected to the disengaging component 340. The fourth power member 361 can be a rotary motor, and the fourth belt drive mechanism 362 can have the same structure as the first belt drive mechanism 1142. The belt of the fourth belt drive mechanism 362 is connected to the fixing seat 343 of the disengaging component 340. The fixing seat 343 of the disengaging component 340 is provided with a connecting member 344 (see...). Figure 11 One end of the connector 344 is connected to the belt of the fourth belt drive mechanism 362, and the other end can move along the fixed frame 322.

[0091] When both sides of the width direction of the expansion frame 320 are provided with a push-open component 340, two fifth drive modules 360 are also provided accordingly. These two fifth drive modules 360 are located on the corresponding fixed frame 322, and the belt transmission directions of these two fifth drive modules 360 are opposite, so that the push-open components 340 on both sides of the width direction of the expansion frame 320 move towards each other or in opposite directions.

[0092] In one embodiment, such as Figure 11 As shown, the expansion module 300 also includes a second cable chain mechanism 370, which is located at the movable connection between the fixed frame 322 and the expansion frame 320. The second cable chain mechanism 370 is used for cable routing, which can prevent damage to the cables.

[0093] In one embodiment, such as Figure 11 As shown, the expansion module 300 also includes a third cable chain mechanism 380, which is located at the movable connection between the fixed frame 322 and the fixed base 343. The third cable chain mechanism 380 is used for cable routing, which can prevent damage to the cables.

[0094] In some embodiments of this application, the automatic capping device 10 also includes a control module. The control module typically adopts a hierarchical architecture. The top layer is a monitoring and management system, which is responsible for monitoring the operating status of the entire device, scheduling tasks, and managing data. The middle layer is a core control unit, including a programmable logic controller (PLC) or an industrial computer (IPC), which receives instructions from the upper layer and converts them into specific control signals for the lower-level actuators. The bottom layer is the drive control of various actuators, such as various motors, cylinders, and solenoid valve controllers, and can also directly control the joint motors and gripping functions of the handling robot 120.

[0095] Solenoid valve controllers are installed in the gas passages of each cylinder to control the basic automated components of the fluid, adjusting the direction, flow rate, speed, and other parameters of the medium. Each gas passage is also equipped with a pressure regulating valve and a filter. The pressure regulating valve operates within a pressure range of 0 MPa to 0.9 MPa, with a limit not exceeding 1.0 MPa. It is primarily used to regulate the pressure of compressed air entering the gas passage, ensuring the system operates under stable pressure. The filter operates within a pressure range of 0 to 0.9 MPa, and its main function is to filter impurities, moisture, and oil from the compressed air, ensuring clean air entering the gas passage and preventing component wear and blockage. The minimum filtration accuracy is 5 μm.

[0096] On the other hand, one embodiment of this application provides a packaging system for photovoltaic modules, which includes the automatic capping device 10 described above.

[0097] This packaging system, through the cooperation of the gripping module 100, the straightening module 200 and the expanding module 300 of the automatic capping device 10, can realize the automatic capping of photovoltaic modules, which can not only improve packaging efficiency, but also reduce labor costs.

[0098] In one embodiment, the packaging system further includes an automatic box-fitting device capable of opening the bottom box 30 and fitting the opened bottom box 30 onto the outer periphery of the photovoltaic module. The automatic box-fitting device can improve the automation level of the entire packaging system.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
