DETAILED DESCRIPTION

[0010] As mentioned in the background art, there are still many problems in the installation process of photovoltaic arrays in the related art, which will be explained in detail below.

[0011] A photovoltaic array is a structure consisting of several pre-assembled photovoltaic racks and photovoltaic modules installed together. These structures are often very large and heavy, and are not susceptible to collisions. Due to the large size and weight of photovoltaic arrays, the current installation process for photovoltaic arrays is primarily performed manually on-site. The loose parts of the photovoltaic racks and boxes of photovoltaic modules are shipped directly from the production site to the final installation location. At the final installation site, a large number of workers assemble the photovoltaic racks from scratch, unpack the photovoltaic module boxes, and manually remove the photovoltaic modules and install them one by one on the photovoltaic racks.

[0012] Due to the harsh installation environment, the large size of the photovoltaic brackets, the heavy weight of the photovoltaic brackets and photovoltaic modules, the large number of fasteners required for installation, and the limited operating space during fastener installation, the manual on-site installation workload is often huge. On-site dimensions must be repeatedly measured and a large number of screws must be tightened. Due to the limited installation space, it is difficult to ensure the consistency of the installation (such as the final installation size of the bracket and the tightening torque of the fasteners). There is even the possibility of accidental bumps and scratches on the photovoltaic modules. In addition, the large number of installers required leads to low assembly efficiency, and the manual use of hand tools for installation and fixation results in poor product consistency.

[0013] 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 with reference to the accompanying drawings.

[0014] Please refer to Figures 1 to 3. In an embodiment of the present application, a photovoltaic array semi-finished product assembly system is provided, including: a photovoltaic bracket assembly system 100, and a photovoltaic bracket and photovoltaic component assembly system 101, wherein the photovoltaic bracket assembly system 100 is connected to the photovoltaic bracket and photovoltaic component assembly system 101; wherein, the photovoltaic bracket assembly system 100 is used to automatically assemble and fix parts and components to form a photovoltaic bracket 102; the photovoltaic bracket and photovoltaic component assembly system 101 is used to automatically assemble and fix the photovoltaic bracket 102 and a number of photovoltaic components 103 to form a photovoltaic array semi-finished product 104.

[0015] The photovoltaic bracket assembly system 100 and the photovoltaic bracket and photovoltaic module assembly system 101 automatically pre-assemble the photovoltaic bracket 102 and the photovoltaic module 103. During this process, the assembly system provides a stable assembly environment, effectively reducing damage to the photovoltaic module 103. Furthermore, the automated pre-assembly process can effectively improve assembly efficiency, reduce the number of assembly personnel, and effectively enhance installation consistency.

[0016] The photovoltaic array semi-finished product 104 is used to be fixed on the photovoltaic panel support structure (not shown) at the installation site. The photovoltaic modules 103 in the photovoltaic array semi-finished product 104 are arranged in an array, with a number of 20 to 32 modules.

[0017] 2 , in this embodiment, the number of the photovoltaic modules 103 in the photovoltaic array semi-finished product 104 is 26. The 26 photovoltaic modules 103 are arranged in an array of 2 rows, with each row including 13 photovoltaic modules 103.

[0018] Continuing to refer to FIG. 3 , in this embodiment, the components include: a support beam 102 a , a purlin 102 b and a purlin support 102 c .

[0019] Please refer to Figure 4. In this embodiment, the support beam 102a and the purlin support 102c are first assembled and fixed, and then the assembled and fixed support beam 102a and the purlin support 102c are fixed to the purlin 102b. The corresponding photovoltaic support assembly system 100 includes: a support beam purlin support pre-assembly device 1001, which is used to assemble and fix the support beam 102a and the purlin support 102c; a support beam purlin assembly device 1002 connected to the support beam purlin support pre-assembly device 1001, which is used to assemble and fix the purlin 102b and the assembled and fixed support beam 102a and the purlin support 102c to form the photovoltaic support 102.

[0020] Please continue to refer to Figure 4. The photovoltaic support assembly system 100 also includes: a support beam loading device 1003 connected to the support beam purlin support pre-installation device 1001, which is used to load and transport multiple support beams 102a, and separate and detect the front support beam 102a; a purlin support loading device 1004 connected to the support beam purlin support pre-installation device 1001, which is used to load and transport multiple purlin supports 102c, and separate the front purlin support 102c; a purlin loading device 1005 connected to the support beam purlin assembly device 1002, which is used to load and transport multiple purlins 102b, and separate and detect the front purlin 102b.

[0021] Please refer to Figure 5. The support beam loading device 1003 includes: a support beam stop and material separation mechanism 1003a, which is used to separate the support beam 102a located at the front; a support beam direction detection mechanism 1003b coordinated with the support beam stop and material separation mechanism 1003a, which is used to detect whether the support beam 102a is placed in the wrong direction; and a support beam flipping device 1003c coordinated with the support beam direction detection mechanism 1003b, which is used to flip the support beam 102a.

[0022] It should be noted that the reason for flipping the support beam 102a is that when the support beam 102a is transporting the upper parts, in order to ensure the stability of its transportation, the wide side of the support beam 102a needs to be attached to the transportation device (i.e. lying flat). When assembling the support beam 102a, since its assembly and fixing position is on its narrow side, in order to ensure the convenience of assembly, it needs to be flipped, and the support beam 102a is flipped from a lying flat form to a lying vertical form.

[0023] The support beam stop and dispensing mechanism 1003a can include a group of blocking cylinders and a group of material dispensing cylinders. First, the blocking cylinder rises to block a row of multiple support beams 102a, and then the material dispensing cylinder extends to block the second support beam 102a. Then the blocking cylinder descends, and the first support beam 102a is transferred separately to complete the material dispensing. Then the blocking cylinder extends again, and the material dispensing cylinder retracts, ready to enter the next material dispensing cycle. The support beam direction detection mechanism 1003b can use image recognition technology, and the image recognition process can be trained and tested in advance using deep learning to improve the accuracy of image recognition. When image recognition determines that the support beam 102a is correctly placed, it needs to cooperate with the support beam flipping device 1003c to flip it; when image recognition determines that the support beam 102a is incorrectly placed, an alarm is directly triggered, and the misplaced support beam 102a is manually removed. The support beam flipping device 1003c can include a set of translation cylinders, a set of lifting cylinders, and a set of rotating cylinders. The rotating cylinders are mounted on the lifting cylinders, which are in turn mounted on the translation cylinders. The rotating cylinders hook the support beam 102a and then follow the lifting cylinders to lift it. Due to gravity, the support beam 102a changes from lying flat (the wide side of the C-shaped steel faces downward) to lying vertically (the narrow side of the C-shaped steel tilts downward). The translation cylinders then drive the support beam 102a to translate to the loading position, the lifting cylinders descend, and then the rotating cylinders rotate open, releasing the workpiece, completing the flipping operation.

[0024] Please refer to Figure 6. The purlin upper component device 1005 includes: a purlin stop and material separation mechanism 1005a, which is used to separate the purlin 102b located at the front; a purlin direction detection mechanism 1005b coordinated with the purlin stop and material separation mechanism 1005a, which is used to detect whether the purlin 102b is placed in the wrong direction; and a purlin flipping device 1005c coordinated with the purlin direction detection mechanism 1005b, which is used to flip the purlin 102b.

[0025] The reason why the purlin 102b needs to be flipped is the same as the reason why the support beam 102a needs to be flipped, and will not be repeated here.

[0026] The purlin stop and material distribution mechanism 1005a can include a purlin fixing and blocking device, a cylinder lifting and separating device (equipped with an inclined rolling bar), and a material receiving device. After the purlin 102b is transferred to the right position, it will be blocked by the purlin fixing and blocking device, and then the cylinder lifting and separating device will rise, driving the front purlin 102b to rise. When the purlin 102b rises to a certain height, it will break away from the purlin fixing and blocking device. Due to the action of gravity, the purlin 102b slides forward on the inclined rolling bar and falls into the material receiving device, completing the material distribution operation of the purlin 102b. The purlin direction detection mechanism 1005b can adopt the detection process of the support beam direction detection mechanism 1003b as described above, and the specific detection and coordination process will not be repeated here. The purlin flipping device 1005c can adopt the structure for flipping the support beam 102a as described above, and the specific flipping process will not be repeated here.

[0027] Please refer to FIG. 7 , the purlin support upper device 1004 includes a purlin support separating device 1004 a for separating the purlin support 102 c located at the front.

[0028] The purlin support material separation device 1004a may include a purlin support fixing and blocking device and a purlin support cylinder pushing and separating device. When the purlin support 102c moves (for example, from left to right) to its designated position, it will be blocked by the purlin support fixing and blocking device, and the conveyor belt will then stop. The purlin support cylinder pushing and separating device will then push the frontmost purlin support 102c from back to front, pushing out the frontmost purlin support 102c, completing the material separation operation of the purlin support 102c.

[0029] Please refer to Figure 8. The support beam purlin support pre-installation device 1001 includes: a support beam positioning and clamping device 1001a, used to position and clamp the support beam 102a; a purlin support positioning and clamping device 1001b that cooperates with the support beam positioning and clamping device 1001a, used to position and clamp the purlin support 102c; a first fixing device 1001c that cooperates with the support beam positioning and clamping device 1001a and the purlin support positioning and clamping device 1001b respectively, used to fix and assemble the support beam 102a and the purlin support 102c.

[0030] The support beam positioning clamping device 1001a and the purlin support positioning clamping device 1001b can both use a driving device to drive a plurality of clamping blocks to move relative to and toward each other (not shown) to achieve the action of clamping and releasing the support beam 102a and the purlin support 102c. The support beam positioning clamping device 1001a and the purlin support positioning clamping device 1001b need to cooperate with each other to ensure that the support beam 102a and the purlin support 102c maintain the correct relative position.

[0031] In this embodiment, the first fixing device 1001c can use an automated bolt tightening device to tighten and secure the support beam 102a and the purlin bracket 102c. In other embodiments, the first fixing device can also fix the support beam and the purlin bracket by bolting, riveting, welding, or pressing.

[0032] Please continue to refer to Figure 4. The photovoltaic bracket assembly system 100 also includes: a bracket beam purlin support assembly rotation device 1006 that is connected between the bracket beam purlin support pre-installation device 1001 and the bracket beam purlin assembly device 1002, and is used to rotate the assembled and fixed bracket beam 102a and the purlin support 102c to a preset angle.

[0033] It should be noted that since the support beams 102a and the purlins 102b are assembled and fixed in a vertical manner, they are arranged parallel to each other during transportation. Therefore, the support beams 102a need to be rotated by a preset angle (90°) before assembly so that they are ultimately perpendicular to the purlins 102b. In other embodiments, when the support beams and the purlins are arranged vertically during transportation, the support beam-purlin support assembly rotation device can be omitted.

[0034] Please refer to FIG. 9 . The support beam purlin support assembly rotating device 1006 includes: a first rotating device 1006 a for rotating the assembled support beam 102 a and the purlin support 102 c to a preset angle.

[0035] The first rotating device 1006a may adopt a structure in which a driving device drives a turntable (not shown) to rotate the assembled support beam 102a and the purlin support 102c to a preset angle so as to be subsequently connected to the purlin support 102c.

[0036] Please refer to Figure 10. The support beam purlin assembly device 1002 includes: a support beam purlin support positioning and clamping device 1002a, which is used to position and clamp the assembled and fixed support beam 102a and the purlin support 102c; a purlin positioning and clamping device 1002b that cooperates with the support beam purlin support positioning and clamping device 1002a, which is used to position and clamp the purlin 102b; a fourth fixing device 1002c that cooperates with the support beam purlin support positioning and clamping device 1002a and the purlin positioning and clamping device 1002b respectively, which is used to fix the purlin 102b and the assembled and fixed support beam 102a and the purlin support 102c.

[0037] The support beam purlin support positioning clamping device 1002a and the purlin positioning clamping device 1002b can both use a structure (not shown) such as the above-mentioned driving device to drive a plurality of clamping blocks to move relative and toward each other, thereby achieving the action of clamping and loosening the assembled support beam 102a, the purlin support 102c, and the purlin 102b. The support beam purlin support positioning clamping device 1002a and the purlin positioning clamping device 1002b need to cooperate with each other to ensure that the support beam 102a and the purlin 102b maintain the correct relative position.

[0038] In this embodiment, the fourth fixing device 1002c may also use an automated bolt tightening device to secure the purlin 102b to the assembled support beam 102a and the purlin bracket 102c. In other embodiments, the fourth fixing device may also secure the support beam and the purlin bracket by bolting, riveting, welding, or pressing.

[0050] Referring to FIG11 and continuing to refer to FIG1 , in this embodiment, the photovoltaic modules 103 are packaged in a packaging box 106. Therefore, the photovoltaic array semi-finished product assembly system further includes a photovoltaic module unpacking system 107 coupled to the photovoltaic support and photovoltaic module assembly system 101 for automatically unpacking the packaging box 106 and removing the photovoltaic modules 103. In other embodiments, if the photovoltaic modules are not packaged in the packaging box, unpacking is not required.

[0051] Please refer to Figure 12, the photovoltaic module unpacking system 107 includes: a packaging box unpacking device 1071, used to cut the tightening strap of the packaging box 106, and open the packaging box 106 to expose the photovoltaic module 103; a photovoltaic module removal device 1072 connected to the packaging box unpacking device 1071, used to remove the photovoltaic module 103.

[0052] Please refer to Figure 13, the packaging box opening device 1071 includes: a first blocking device 1071a, used to temporarily block the unopened packaging box 106; a tape cutting device 1071b coordinated with the first blocking device 1071a, used to cut the tightening tape of the packaging box 106; and an opening device 1071c coordinated with the tape cutting device 1071b, used to open the packaging box 106 and expose the photovoltaic module 103.

[0053] The first blocking device 1071a can detect the packaging box 106 through an infrared light component (not shown). When the infrared light is blocked by the packaging box 106, it means that the packaging box 106 has reached the preset position. At this time, the automatic block (not shown) is used to temporarily block the packaging box 106. After the tightening strap of the packaging box 106 is cut and the box is opened, the automatic block retracts and the packaging box 106 is transferred to the next workstation.

The opening device 1071c can use a structure (not shown) in which a drive device drives the extension and contraction of a suction cup structure. By extending the suction cup structure, the side of the packaging box 106 that needs to be opened is adsorbed, and then the corresponding side is opened by retracting the suction cup structure.

[0054] Continuing with reference to FIG. 13 , the packaging box unpacking device 1071 further includes: a packaging box loading device 1071 d coupled to the first blocking device 1071 a for loading and transporting the packaging box 106 .

[0057] The second blocking device 1072a can adopt a structure similar to the first blocking device 1071a described above, but in order to prevent the second blocking device 1072a from causing collisions with the exposed photovoltaic module 103, a buffer layer (not shown) can be coated on the surface of the automatic block of the second blocking device 1072a. The positioning device 1072b and the retrieval device 1072c cooperate with each other. The positioning device 1072b can locate the center area of ​​the photovoltaic module 103 through image recognition. The retrieval device 1072c can be a robotic arm. The gripping end of the retrieval device 1072c can use a suction cup structure to absorb and fix the located center area of ​​the photovoltaic module 103.

[0059] The photovoltaic assembly regular arrangement device 1073 may include a counting component, a detection component, and a blocking component (not shown), wherein the detection component may be detected by the infrared light component as described above. When the infrared light component is blocked and then unblocked during the detection process, the count of the counting component increases by 1. When the count value reaches the fixed number, the blocking component is used to temporarily block the photovoltaic assembly 103 that is subsequently transmitted. The blocking component may have the same structure as the second blocking device 1072a described above. At this time, the unblocked photovoltaic assembly 103 is regularly arranged into a group (26 pieces are used as an example in this embodiment). The photovoltaic assembly loading device 1074 may include a truss manipulator and a plurality of photovoltaic assembly grasping devices installed at the end of the truss manipulator. The photovoltaic module grasping device can grasp a group of the said photovoltaic modules 103 in an orderly manner once or multiple times and rise up.

Then, the semi-finished product moving and lifting device 1083 suspends and lifts one of the interlayer spacers 1081 and covers it on the photovoltaic array semi-finished product 104 to separate two layers of the photovoltaic array semi-finished product 104. After the next photovoltaic array semi-finished product 104 is in place, the semi-finished product moving and lifting device 1083 suspends and lifts this photovoltaic array semi-finished product 104 and moves it above the semi-finished product trolley 1082, and then places this photovoltaic array semi-finished product 104 on the interlayer spacer 1081 on the semi-finished product trolley 1082. The above steps are performed in sequence until a stack of photovoltaic array semi-finished products 104 is fully stacked. After the semi-finished product trolley 1082 is full, the entire stack of the photovoltaic array semi-finished products 104 is transported into storage via the trolley traction device 1084, and an empty semi-finished product trolley 1082 is tractioned and parked at the stacking position, and the above steps are repeated in sequence.
