Description

Technical Field

[0001] The present application relates to but is not limited to the technical field of photovoltaic module production equipment, and in particular to an automatic photovoltaic module framing machine. Background Art

[0002] The automatic framing machine in the photovoltaic module packaging equipment is an important process equipment in the photovoltaic module production process. The framing quality directly determines the quality of the finished photovoltaic module. Most of the existing framing equipment on the market has a complex structure and cumbersome actions. In the framing process, the alignment action is more important. The alignment action is to push the long and short sides of the module to the center. Therefore, the alignment components are installed around the solar cell. At the same time, there are components around the solar cell for corner assembly, so the required parts are the most numerous and complex.

[0003] like Figure 1 As shown, a feeding mechanism 02, a straightening mechanism 04, a leveling mechanism (not shown in the figure), an angle assembly mechanism 03, a positioning mechanism 05, etc. are provided at both ends of the body of the conventional framing machine. When framing the photovoltaic module, the photovoltaic module is firstly transferred to a predetermined position by the feeding mechanism 02, placed on the suction cup of the positioning mechanism 05, and then straightened by the straightening mechanism 04, and then raised to a predetermined angle assembly position by the leveling mechanism, and finally the photovoltaic module is angled by the angle assembly mechanism 03 to complete the automatic framing of the photovoltaic module.

[0004] Traditional frame machines can only produce components of the same specification after being set up once. If components of different specifications are produced, the various components in the frame machine need to be reset. Because traditional frame machines have many components and complex structures, they take up a lot of space and are time-consuming, making it inconvenient to install and debug automatic frame machines. Summary of the invention

[0005] The embodiment of the present application provides an automatic framing machine for photovoltaic modules, which solves the problem that the current automatic framing machines have many components and are time-consuming to install.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0007] An embodiment of the present application provides an automatic framing machine for photovoltaic modules, including: a frame, a workbench, a leveling mechanism, a positioning mechanism, and a corner aligning and assembling mechanism. Among them, the workbench bears the photovoltaic module; the leveling mechanism is located between the frame and the workbench and is used to level the photovoltaic module; the positioning mechanism is arranged on the frame and is used to position the photovoltaic module; the corner aligning and assembling mechanism is arranged on the frame and is used to adjust the photovoltaic module on the workbench. The corner aligning and assembling mechanism includes a corner assembling module and a corner aligning module. The corner assembling module includes a plurality of corner assembling stroke components, which are movably connected to the frame and are arranged corresponding to each side of the photovoltaic module. A plurality of corner assembling pressing components are fixed on the corner assembling stroke components. The corner assembling stroke components can move relative to the frame along the extending direction of the photovoltaic module to drive the corner assembling pressing components to move to the corner assembling position. The corner assembling pressing components are used to perform corner assembling operations on the photovoltaic module at the corner assembling position; the corner aligning module includes a first corner aligning pushing component, which is arranged on the corner assembling stroke component. The corner assembling stroke component can drive the first corner aligning pushing component to move to the corner aligning position. The first corner aligning pushing component is used to perform corner aligning operations on the photovoltaic module at the corner aligning position.

[0008] An embodiment of the present application provides an automatic framing machine for photovoltaic modules. During the framing process, when performing corner aligning and assembling operations on the photovoltaic module, the workbench and the frame provide support for the corner aligning and assembling operations of the photovoltaic module. The photovoltaic module is located on the workbench, and the workbench drives the photovoltaic module to switch between the corner aligning position and the corner assembling position. The photovoltaic module is first in the corner aligning position, and the corner aligning module performs corner aligning operations on the photovoltaic module. The two corner aligning pushing components located on the long sides of the photovoltaic module act simultaneously to push the photovoltaic module towards the center position between them to complete the corner aligning operation of the long sides of the photovoltaic module; the two corner aligning pushing components located on the short sides of the photovoltaic module act simultaneously to push the photovoltaic module towards the center position between them to complete the corner aligning operation of the short sides of the photovoltaic module. Performing corner aligning operations on the photovoltaic module before performing corner assembling operations avoids misalignment of the photovoltaic module during corner assembling, thereby improving production quality. When changing the specifications of the photovoltaic module, the corner assembling module needs to be adjusted to a new position to adapt to the new specifications of the photovoltaic module. The first corner aligning pushing component also requires this operation. By directly arranging the first corner aligning pushing component on the corner assembling stroke component, the first corner aligning pushing component is adjusted while adjusting the corner assembling stroke component, without the need to additionally adjust the position of the first corner aligning pushing component, reducing the number of adjustments, making the debugging and model change of the automatic framing machine of the present invention more convenient. At the same time, the driving and transmission components required for adjusting the position of the first corner aligning pushing component are eliminated, the structure is simpler, and it is more convenient for the installation of the automatic framing machine. Compared with the solution in the related art where the corner aligning module and the corner assembling module are separated, the present application adopts an associated setting of the two, effectively simplifying the mechanism, facilitating installation, reducing some components of the automatic framing machine without affecting the framing quality, and solving the problems of time consumption and inconvenient installation. Further, the equipment cost is saved.

[0009] Furthermore, the first straightening push component is arranged at the front end of the angular stroke component. The front end of the angular stroke component is that end close to the photovoltaic component. The first straightening push component is arranged here. Firstly, the first straightening push component is closer to the photovoltaic component, has a short action stroke, consumes lower power, and is more energy-saving and environmentally friendly. Secondly, due to the short action stroke, the first straightening push component can be arranged smaller, making it more compact and saving materials. Finally, the action of the first straightening push component is not easily interfered with by the angular stroke component, thereby improving the reliability of the mechanism.

[0010] Furthermore, the first straightening push component is arranged at the lower side of the angular stroke component. In order to reduce energy consumption, save energy and avoid unnecessary movements, the straightening module should be arranged between the workbench and the angular stroke module, so that the workbench passes through the straightening module and the angular stroke module in sequence during operation. The photovoltaic components can be fed in from the upper side of the rack or from the lower side. Feeding in from the lower side using a conveyor belt is more stable, while feeding in from the upper side requires a sling, which has poor stability. Considering the stability of the photovoltaic components fed into the workbench, the first straightening push component is arranged at the lower side of the angular stroke component.

[0011] Furthermore, in order to make the operation of the first alignment push component more concise and convenient while saving costs during the alignment process, the first alignment push component can be arranged at the lower side of the front end of the angular stroke component.

[0012] Furthermore, the calibration module includes a second calibration push component and a calibration stroke component. The second calibration push component is arranged on the calibration stroke component. The calibration stroke component is used to be movably connected to the frame of the photovoltaic production equipment and is arranged on the side of the photovoltaic component where the first calibration push component is not arranged. The calibration stroke component can drive the second calibration push component to move to the calibration position. The second calibration push component is used to perform calibration operations on the photovoltaic component in the calibration position. In order to cope with the situation where it is inconvenient to set the calibration push component on the corresponding group angular stroke component, such as the situation that it may interfere with the loading and unloading of the photovoltaic component, the present application sets an independent calibration stroke component to drive the second calibration push component, so as to facilitate the present mechanism to adapt to photovoltaic components of different specifications. Compared with the traditional equipment in which the adjustment operation and the calibration operation are combined into one, the independent calibration stroke component reduces the stroke of the calibration push component, is more energy-saving, and the position adjustment is more convenient.

[0013] Furthermore, the first straightening push component is located on the short side of the photovoltaic component, and the second straightening push component is located on the long side of the photovoltaic component. Since the space on the short side of the photovoltaic component is relatively narrow, and the second straightening push component requires a matching straightening stroke component, the required installation space is relatively large. Therefore, the smaller first straightening push component is set on the short side of the photovoltaic component, and the larger second straightening push component is set on the long side of the photovoltaic component, so that the structure of the entire photovoltaic component framing machine production device is more reasonable.

[0014] Further, the alignment and pushing component includes an alignment and pushing mounting plate, a driving member, and a pushing head. The alignment and pushing mounting plate is fixed to the corner assembling travel component or the alignment travel component. The driving member is fixed on the alignment and pushing mounting plate, and the driving member is in transmission connection with the pushing head. The driving member drives the pushing head to move relative to the rack along the extension direction of the photovoltaic module, so as to perform an alignment operation on the photovoltaic module at the alignment position. Among them, the alignment and pushing mounting plate facilitates the installation of the alignment and pushing component. The driving member drives the pushing head to move, and the pushing head moves relative to the rack along the extension direction of the photovoltaic module, thereby realizing the alignment operation on the photovoltaic module. The structure is simple and the action is reliable.

[0015] Further, the axis of the pushing head is perpendicularly arranged with respect to the axis of the output shaft of the driving member. When the axis of the pushing head is arranged parallel to the axis of the output shaft of the driving member, its size is limited by the distance between the driving member and other components, such as the distance between the driving member and the corner assembling travel component. However, when the axis of the pushing head is perpendicularly arranged with respect to the axis of the output shaft of the driving member, the size of the pushing head is not easily restricted by this. The size of the pushing head can be made larger, so as to increase the contact area with the photovoltaic module, make the force on the photovoltaic module more balanced during the alignment operation, and improve the alignment effect.

[0016] Further, the driving member is a rotary cylinder. The pushing head is fixed to the output end of the rotary cylinder. The rotary cylinder drives the pushing head to move relative to the rack along the extension direction of the photovoltaic module and drives the pushing head to rotate along the axis of the output shaft of the rotary cylinder. Since the rotary cylinder can provide both linear drive along its output shaft axis and rotary drive along its output shaft axis, during the alignment operation, the rotary cylinder first drives the pushing head to rotate to the vertical state so that it can avoid other mechanisms during subsequent movement. Then, the rotary cylinder linearly drives the pushing head to move relative to the rack along the extension direction of the photovoltaic module to realize the alignment operation on the corresponding side of the photovoltaic module, making the mechanism more flexible and improving the practicability.

[0017] Further, the leveling mechanism includes a driving assembly. The driving assembly includes a driving member, a synchronous rod, and a plurality of lifting link groups. The synchronous rod is connected to the plurality of lifting link groups. The driving member drives the plurality of lifting link groups to move through the synchronous rod, so as to raise or lower the workbench. The synchronous rod is connected to the plurality of lifting link groups. When the driving member drives the synchronous rod to move, the synchronous rod can drive the plurality of lifting link groups to perform lifting actions synchronously, so that the workbench rises or falls. There is no need to adjust the levelness of the connection position between the lifting link group and the workbench, and the synchronism of the lifting actions of the lifting link group will not be affected by the levelness adjustment error. The installation is simple and the synchronism of the lifting actions of the lifting link group is good.

[0018] Further, the lifting link group includes a first link and a second link fixed together at an angle. The first end of the first link is hinged to the synchronization rod, and the second end is hinged to the frame; the end of the second link is hinged to the workbench. When the synchronization rod moves linearly under the drive of the driving member, the first end of the first link moves linearly with the synchronization rod, and the second end generates a clockwise or counterclockwise rotational force, driving the second link to rotate clockwise or counterclockwise, causing the second link to swing up and down, and driving the workbench to rise and fall.

[0019] Further, the first link is connected to the base through a first bearing seat, and the second link is connected to the workbench through a second bearing seat. Taking the first bearing seat as the inner support point for the hinge between the first link and the base, and the second bearing seat as the outer support point for the hinge between the second link and the workbench, so that the first link and the second link are stably fixed.

[0020] Further, the first link and the second link are fixed through a first rotating shaft. The first rotating shaft connects one ends of two second links, and the other ends of the two second links are connected through a second rotating shaft. The first rotating shaft and the second rotating shaft are arranged in parallel. So that the first link, the two second links, the first rotating shaft and the second rotating shaft form a lifting link group, moving simultaneously and maintaining synchronism.

[0021] Further, the two second links are arranged at intervals along the first rotating shaft and perpendicular to the first rotating shaft.

[0022] Further, the positioning mechanism includes a first suction cup assembly and N auxiliary suction cup assemblies. Among them, the first suction cup assembly is used for adsorbing the photovoltaic module and is arranged on the frame; the auxiliary suction cup assemblies, the adsorption directions of the auxiliary suction cup assemblies are the same as that of the first suction cup assembly. The auxiliary suction cup assemblies are movably connected to the frame. The auxiliary suction cup assemblies can move to a first height position and a second height position. The height direction is opposite to the adsorption direction of the auxiliary suction cup assemblies. When the auxiliary suction cup assemblies are in the first height position, the auxiliary suction cup assemblies are lower than the first suction cup assembly. When the auxiliary suction cup assemblies are in the second height position, the auxiliary suction cup assemblies are flush with the first suction cup assembly. When the auxiliary suction cup assemblies are flush with the first suction cup assembly, the auxiliary suction cup assemblies and the first suction cup assembly are arranged in a direction perpendicular to the height direction. During the process of adsorbing a photovoltaic module with a small area, the auxiliary suction cup assemblies do not work. During the process of adsorbing a photovoltaic module with a large area, the first suction cup assembly and the auxiliary suction cup assemblies work simultaneously, which is beneficial to resource conservation and control of the adsorption force.

[0023] Further, when the N auxiliary suction cup assemblies are flush with the first suction cup assembly, the N auxiliary suction cup assemblies and the first suction cup assembly are arranged in a straight line.

[0024] Further, the first suction cup assembly includes a static suction cup group and M moving suction cup groups, where M is a positive integer greater than or equal to 1. The static suction cup group is located at the second height position, and the M moving suction cup groups can respectively move from the second height position to M height positions, all of which are higher than the second height position.

[0025] Further, the auxiliary suction cup assembly includes an auxiliary static suction cup group and L auxiliary moving suction cup groups, where L is a positive integer greater than or equal to 1. When the auxiliary suction cup assembly moves to the second height position, the auxiliary static suction cup group is located at the second height position, and the L auxiliary moving suction cup groups can respectively move from the second height position to L height positions, all of which are higher than the second height position. Further, the first suction cup assembly includes a first suction cup and a first pre-suction cup. The first pre-suction cup can move to the second height position and the third height position. When the first pre-suction cup moves to the third height position, the first suction cup is lower than the first pre-suction cup. When the first pre-suction cup moves to the second height position, the first suction cup is flush with the first pre-suction cup. During the adsorption process of the first suction cup assembly on the photovoltaic module, the photovoltaic module is first adsorbed on the first pre-suction cup, and then jointly adsorbed by the first pre-suction cup and the first suction cup. That is, the first suction cup assembly adsorbs the photovoltaic module in two steps, which can make the positioning of the photovoltaic module by the photovoltaic module positioning device more accurate.

[0026] Further, the photovoltaic module corresponding to the first suction cup assembly in size is the first battery module. The number of the first pre-suction cups is four, and the four first pre-suction cups are respectively used to adsorb the four corners of the first battery module. During the installation of the frame of the photovoltaic module, the accuracy of the four corners of the photovoltaic module is more important than that of other positions. Therefore, positioning the four corners of the photovoltaic module first can better ensure the position accuracy of the photovoltaic module.

[0027] Further, the N auxiliary suction cup assemblies include a second suction cup assembly. The second suction cup assembly includes a second suction cup and a second pre-suction cup. When the second suction cup assembly moves to the second height position, the second pre-suction cup can move to the second height position and the third height position. When the second pre-suction cup moves to the third height position, the second suction cup is lower than the second pre-suction cup. When the second pre-suction cup moves to the second height position, the second suction cup is flush with the second pre-suction cup. With such a structural form, that is, the second suction cup assembly adsorbs the photovoltaic module in two steps, which can make the positioning of the photovoltaic module by the photovoltaic module positioning device more accurate.

[0028] Further, second suction cup assemblies are arranged on both opposite sides of the first suction cup assembly. For a photovoltaic module in the shape of a rectangular plate, the position of the center of the device during the installation process will not have a large deviation, which is convenient for the framing device to frame the photovoltaic module.

[0029] Further, the photovoltaic module corresponding to the area formed by the second suction cup assemblies on both sides is the second battery module. Each second suction cup assembly has two second pre-suction cups. The four second pre-suction cups on the second suction cup assemblies on both sides are respectively used to adsorb the four corners of the second battery module. During the adsorption process of the second suction cup assembly to the second battery module, the four corners of the second battery module can be positioned first to ensure the accuracy of the four corners of the second battery module.

Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0055] The embodiments of the present application provide an automatic framing machine for photovoltaic modules. The solar cell is composed of a glass panel, a battery string, a laying film, and a frame for fixing. During the production process of the solar cell, it needs to go through processes such as material cutting, laying, lamination, and frame corner assembly. The corner assembly process is used to combine and compress the frame of the solar cell, so that the frame provides support and protection for other components of the solar cell.

[0056] Referring to Figure 2 , the automatic framing machine for photovoltaic modules includes a frame 1. The frame 1 is formed by fixedly connecting a plurality of vertically arranged support columns 11 and a plurality of horizontally arranged connecting rods 12, and is rectangular as a whole. A connecting piece 13 is fixed at the bottom of the support column 11, and the connecting piece 13 can fix the device to the ground by means of bolt connection or the like. In the related art, the long and short side alignment modules 62 align the components. The long side alignment head is installed at the front end of the rack. The servo motor drives the gear to drive the rack to move on the linear guide rail to push the component. Two sets of alignment heads on the same side are connected by a long shaft to act together. The short side alignment mechanism pushes the alignment head by the alignment cylinder, and the servo motor drives the lead screw nut to adjust the position of the alignment cylinder. The components of the long and short side alignment mechanisms are numerous, and the structures of the gear rack and the lead screw nut are costly, and the installation and debugging workload is large.

[0057] Referring to Figure 2 , in an embodiment of the present application, the number of the support columns 11 is eight, which are respectively arranged at the four corners of the frame 1, and at least two connecting rods 12 are fixed between adjacent support columns 11.

[0058] Referring to Figure 2 , a feeding mechanism 2 is provided on the frame 1. The feeding mechanism 2 is composed of a plurality of parallel conveyor belts. When loading and unloading, the photovoltaic module is placed on the conveyor belt, and is loaded from one side of the frame 1 and unloaded from the other side. The plurality of conveyor belts can provide multi-point support for the photovoltaic module, making the photovoltaic module more stable during transportation.

[0059] It should be noted that the conveying direction of the conveyor belt can be set parallel to the short side of the photovoltaic module or parallel to the long side direction of the photovoltaic module, such as Figure 3As described above, in an embodiment of the present application, the conveying direction of the conveyor belt is set along the short side direction of the photovoltaic module. There are a total of five conveyor belts. The conveyor belts on both sides are provided with a downwardly concave avoidance groove 22 in the middle for avoiding the movement of components such as the pusher head.

[0060] As Figure 2 and Figure 3 As described above, the photovoltaic module is not shown in the figure. The photovoltaic module can be regarded as a horizontally placed rectangular plate, with its long side corresponding to the long side of the frame 1 and its short side corresponding to the short side of the frame 1.

[0061] As Figure 2 and Figure 3 As described above, an embodiment of the present application provides an automatic frame mounting machine for photovoltaic modules, including: a frame 1, a workbench 3, a feeding mechanism 2, a leveling mechanism, a positioning mechanism 55, and a regularizing and corner assembling mechanism 6 (the leveling mechanism is not shown in the figure). Among them, the feeding mechanism 2 is connected to the frame 1 for sending the photovoltaic module into the frame 1 for frame mounting, and then sending the photovoltaic module out of the frame 1 after the frame mounting is completed. The regularizing and corner assembling mechanism 6 includes a corner assembling module 61 and a regularizing module 62. The corner assembling module 61 is used to perform corner assembling operations on the photovoltaic module at the corner assembling position, and the regularizing module 62 is used to perform regularizing operations on the photovoltaic module at the regularizing position. The leveling mechanism is located inside the frame 1 and is connected to the frame 1 for synchronously and stably lifting the positioning mechanism 5, and the positioning mechanism 5 is arranged on the leveling mechanism for adsorbing the photovoltaic module to the corresponding position, facilitating the regularizing and corner assembling mechanism to perform regularizing and corner assembling operations on the photovoltaic module and improving the frame mounting quality of the photovoltaic module.

[0062] As Figure 2 As described above, a corner assembling module 61 is arranged on the upper side of the feeding mechanism 2. The corner assembling module 61 includes a plurality of corner assembling stroke components 611, and is provided corresponding to each side of the photovoltaic module. A plurality of corner assembling and pressing components 612 are fixed on the corner assembling stroke components 611, and the corner assembling and pressing components 612 are used to perform corner assembling operations on the photovoltaic module at the corner assembling position.

[0063] Among them, the sides of the photovoltaic module are the long and short sides of the photovoltaic module in the above text.

[0064] In an embodiment of the present application, referring to Figure 2 , the number of the corner assembling stroke components 611 is four. The four corner assembling stroke components 611 are respectively arranged on the four sides of the photovoltaic module, with two located on the long side of the photovoltaic module and two located on the short side of the photovoltaic module. Four corner assembling and pressing components 612 are fixed on each corner assembling stroke component 611 located on the long side of the photovoltaic module, and three corner assembling and pressing components 612 are fixed on each corner assembling stroke component 611 located on the short side of the photovoltaic module. The corner assembling and pressing components 612 can press the frame of the photovoltaic module tightly.

[0065] As Figure 5As described above, there are various ways to implement the corner assembly and fixing component 612, and any structure that can implement the extrusion action is acceptable. In an embodiment of the present application, the corner assembly and fixing component 612 includes a corner cylinder 6121, which is fixed on the corner travel component 611. The output shaft of the corner cylinder 6121 is arranged vertically, and the output end of the corner cylinder 6121 is fixedly connected with a corner pushing block 6122. There are 1 to 4 supporting rollers 6123 arranged under each corner pushing block 6122. The multiple supporting rollers 6123 are arranged horizontally and fixed on the corner travel component 611.

[0066] It should be noted that the corner assembly operation refers to the operation in which the corner cylinder 6121 drives the corner pushing block 6122 to move towards the supporting roller 6123, and the corner pushing block 6122 and the supporting roller 6123 cooperate to press and fasten the frame of the photovoltaic module firmly.

[0067] In order to enable the corner assembly module 61 to adapt to photovoltaic modules of different sizes and improve the universality of the device, the corner travel component 611 is movably connected to the frame 1 and can move relative to the frame 1 along the extending direction of the photovoltaic module, so as to drive the corner assembly and fixing component 612 to move to the corner assembly position.

[0068] In an embodiment of the present application, with reference to Figure 4 and Figure 5 As described above, the corner travel component 611 includes a corner base body 6111. The corner cylinder 6121 and the supporting rollers 6123 are both fixed on the corner base body 6111. A nut 6112 is fixed under the corner base body 6111. The nut 6112 is inserted and threadedly connected with a lead screw 6113. The lead screw 6113 is rotationally connected to the frame 1 through a connecting seat and is driven by a corner motor 6114 fixed on the frame 1, so as to drive the movement of the corner base body 6111. The corner base body 6111 then drives the corner assembly and fixing component 612 to move to the corner assembly position.

[0069] Among them, there are various forms of movable connection. With reference to Figure 4 and Figure 8 As described above, any connection that can realize the horizontal movement of the corner travel component 611 relative to the frame 1 is acceptable. In an embodiment of the present application, a sliding connection is adopted between the component travel component and the frame 1, and the sliding connection can be realized by a slider 6236 rail assembly; the number of nuts 6112 and lead screws 6113 can be multiple, and the multiple lead screws 6113 are arranged in parallel.

[0070] It should be noted that, as Figure 2 and Figure 3 As described above, moving along the extending direction of the photovoltaic module relative to the frame 1 refers to moving towards the photovoltaic module, that is, the corner travel components 611 and the like located on each side of the photovoltaic module horizontally close to the center of the photovoltaic module.

[0071] Referring to Figure 2 , in order to ensure the effect of the corner assembling operation, a rectifying operation needs to be carried out before the components to prevent misalignment during the assembly of the photovoltaic modules. A rectifying module 62 is provided between the corner assembling module 61 and the feeding mechanism 2. The rectifying module 62 includes a plurality of first rectifying pushing components 621 and a plurality of second rectifying pushing components 622. The first rectifying pushing components 621 and the second rectifying pushing components are respectively arranged on the sides of the photovoltaic module. Among them, the first rectifying pushing components 621 and the second rectifying pushing components 622 are located on different sides of the photovoltaic module. The rectifying pushing components are used to push the photovoltaic module from the sides of the photovoltaic module to the central position relative to the workbench 3, that is, to perform a rectifying operation on the photovoltaic module at the rectifying position.

[0072] During the rectifying operation, as Figure 2 , the two second rectifying pushing components 622 located on the long side of the photovoltaic module act simultaneously to push the photovoltaic module to the central position between them to complete the rectifying operation of the long side of the photovoltaic module; the two first rectifying pushing components 621 located on the short side of the photovoltaic module act simultaneously to push the photovoltaic module to the central position between them to complete the rectifying operation of the short side of the photovoltaic module. Performing the rectifying operation on the photovoltaic module before the corner assembling operation avoids misalignment of the photovoltaic module during corner assembling, thereby improving the production quality.

[0073] Referring to Figure 4 , Figure 7 and Figure 8 , in order to enable the rectifying module 62 to adapt to photovoltaic modules of different sizes and improve the universality of the device, the rectifying components need to be adjusted in a position similar to that of the corner assembling stroke component 611. Therefore, the first rectifying pushing component 621 is fixed on the corner assembling base 6111 of the corner assembling stroke component 611, and the second rectifying pushing component 622 is arranged on the rectifying stroke component 623. Among them, the rectifying stroke component 623 is arranged on the frame 1 and moves similarly to the corner assembling stroke component 611, and is used to drive the second rectifying pushing component 622 to the rectifying position, while the first rectifying pushing component 621 is driven by the corner assembling stroke component 611.

[0074] As Figure 2 shown, by directly arranging the first rectifying pushing component 621 on the corner assembling stroke component 611, the first rectifying pushing component 621 is adjusted while adjusting the corner assembling stroke component 611. There is no need to additionally adjust the position of the first rectifying pushing component 621, reducing the number of adjustments, making the debugging and model change of the mechanism more convenient. At the same time, the driving and transmission components required for the position adjustment of the first rectifying pushing component 621 are eliminated, the structure is simpler, and it is more convenient for the installation of the device.

[0075] In order to make the device more compact and improve its reliability, in an embodiment of the present application, referring to Figure 2, the first alignment pushing component 621 is arranged at the front end of the corner forming stroke component 611. The front end of the corner forming stroke component 611 is the end close to the photovoltaic module. Arranging the first alignment pushing component 621 here, firstly, the first alignment pushing component 621 is closer to the photovoltaic module, with a shorter acting stroke, lower power consumption, and is more energy-saving and environmentally friendly. Secondly, due to the short acting stroke, the first alignment pushing component 621 can be made more compact, making it more compact and also saving materials. Finally, the movement of the first alignment pushing component 621 is not easily interfered by the corner forming stroke component 611, improving the reliability of this mechanism.

[0076] To reduce energy consumption, save energy, and avoid unnecessary actions, such as Figure 2 As shown, the alignment module 62 should be arranged between the workbench 3 and the corner forming module 61, so that the workbench 3 passes through the alignment module 62 and the corner forming module 61 in sequence. The photovoltaic module can be fed from the upper side of the frame 1 or from the lower side. Feeding from the lower side is more stable using the conveyor belt 21, while feeding from the upper side requires a lifting tool and has poor stability. Considering the stability of the photovoltaic module feeding onto the workbench 3, in an embodiment of the present application, the first alignment pushing component 621 is arranged on the lower side of the corner forming stroke component 611.

[0077] It should be noted that referring to Figure 2 , the first alignment pushing component 621 can be located on the short side or the long side of the photovoltaic module. Similarly, for the second alignment pushing component 622, as long as it is ensured that the first alignment pushing component 621 and the second alignment pushing component 622 are not opposite to each other.

[0078] In an embodiment of the present application, referring to Figure 2 and Figure 9 , the first alignment pushing component 621 is located on the short side of the photovoltaic module, and one is arranged on each side. The second alignment pushing component 622 is located on the long side of the photovoltaic module, and two are arranged on each side. Considering that the space on the short side of the photovoltaic module is relatively narrow, and the second alignment pushing component 622 requires a supporting alignment stroke component 623, and the required installation space is relatively large. Therefore, the first alignment pushing component 621 with a smaller volume is arranged on the short side of the photovoltaic module, and the second alignment pushing component 622 with a larger volume is arranged on the long side of the photovoltaic module, making the structure of the entire photovoltaic production device more reasonable.

[0079] In addition, as Figure 8 and Figure 9As shown, the second alignment driving component 622 and the alignment stroke component 623 are provided to address the situation where it is not convenient to arrange the alignment driving component corresponding to the corner assembly stroke component 611, such as the situation where interference may occur with the loading and unloading of photovoltaic modules. Among them, the second alignment driving component 622 is arranged on the alignment stroke component 623, and the alignment stroke component 623 is movably connected to the frame 1 of the photovoltaic production equipment.

[0080] Referring to Figure 8 , by setting up an independent alignment stroke component 623 to drive the second alignment driving component 622, it is convenient for this mechanism to adapt to photovoltaic modules of different specifications. Compared with the traditional equipment where the adjustment operation and the alignment operation are combined into one, the independent alignment stroke component 623 reduces the stroke of the alignment driving component, is more energy-efficient, and the position adjustment is also more convenient.

[0081] Referring to Figure 9 , it should be noted that there are various ways to implement the alignment stroke component 623, as long as it can drive the second alignment driving component 622 to achieve reciprocating motion. In an embodiment of the present application, the alignment stroke component 623 includes an alignment stroke mounting plate 6231, the alignment stroke mounting plate 6231 is fixed on the frame 1, the lower side of the alignment stroke mounting plate 6231 is movably connected with an alignment stroke motor 6233 through a driving mounting frame 6232, the output end of the alignment stroke motor 6233 penetrates through the alignment stroke mounting plate 6231, and a gear 6234 is fixedly connected to the upper side of the alignment stroke mounting plate 6231. The gear 6234 meshes with a rack 6235, the rack 6235 is fixed to the second alignment driving mounting plate 6221 of the second alignment driving component 622, a slider 6236 is fixed to the lower side of the second alignment driving mounting plate 6221 of the second alignment driving mechanism, and the slider 6236 slides on a linear guide rail 6237 fixed to the upper side of the alignment stroke mounting plate 6231. The alignment stroke motor 6233 of the alignment stroke component 623 drives the gear 6234 to rotate, the gear 6234 drives the rack 6235 to move, and the rack 6235 drives the second alignment driving mechanism to slide on the linear guide rail 6237, so as to achieve the purpose of adjusting the position of the second alignment driving component 622.

[0082] It should be noted that the output end of the alignment stroke motor 6233 is not the output end in the narrow sense. When the alignment stroke motor 6233 is connected and driven through a reducer, it refers to the output end of the reducer.

[0083] In an embodiment of the present application, such as Figure 6 , Figure 7 and Figure 9As shown in the figure, the alignment and pushing assembly includes an alignment and pushing mounting plate, a driving member, and a pushing head. The alignment and pushing mounting plates corresponding to the two alignment and pushing assemblies are the first alignment and pushing mounting plate and the second alignment and pushing mounting plate 6221 respectively. The first alignment and pushing mounting plate is fixed to the corner assembly base 6111 of the corner assembly 611, and the second alignment and pushing mounting plate 6221 is fixed to the slider 6236 of the alignment travel assembly 623. The driving members corresponding to the two alignment and pushing assemblies are the first driving member 6212 and the second driving member 6222 respectively. The first driving member 6212 is fixed on the first alignment and pushing mounting plate, and the second driving member 6222 is fixed on the second alignment and pushing mounting plate 6221. The pushing heads corresponding to the two alignment and pushing assemblies are the first pushing head 6213 and the second pushing head 6223 respectively. The first driving member 6212 is in transmission connection with the first pushing head 6213, and the second driving member 6222 is in transmission connection with the second pushing head 6223. The first driving member 6212 drives the first pushing head 6213 to move relative to the frame 1 along the extension direction of the photovoltaic module, so as to perform alignment operation on the photovoltaic module at the alignment position. The second driving member 6222 drives the second pushing head 6223 to move relative to the frame 1 along the extension direction of the photovoltaic module, so as to perform alignment operation on the photovoltaic module at the alignment position.

[0084] Referring to Figure 2 , the alignment and pushing mounting plate facilitates the installation of the alignment and pushing assembly. The driving member drives the pushing head to move, and the pushing head moves relative to the frame 1 along the extension direction of the photovoltaic module, thereby realizing the alignment operation on the photovoltaic module. The structure is simple and the action is reliable.

[0085] It should be noted that the transmission connection refers to any connection method that can transmit the output motion of the driving member to the pushing head. By way of example, belt drive, chain drive, connection through a reduction mechanism, fixed connection, etc.

[0086] When the axis of the pushing head is arranged parallel to the axis of the output shaft of the driving member, its size is limited by the distance between the driving member and other components, such as the distance between the driving member and the corner assembly 611. In order to make the size of the pushing head larger and increase the contact area between the pushing head and the photovoltaic module, so that the photovoltaic module is more evenly stressed during the alignment operation, the axis of the pushing head is arranged perpendicular to the axis of the output shaft of the driving member. The size of the pushing head is not easily limited, and the size of the pushing head can be made larger, thereby improving the alignment effect.

[0087] To solve the problem that the pushing head may interfere with the movement of other mechanisms, referring to Figure 2 , such as the operation of the feeding mechanism 2 to feed the photovoltaic module into or out of, the driving member is a rotary cylinder, the pushing head is fixed to the output end of the rotary cylinder, and the rotary cylinder drives the pushing head to move relative to the frame 1 along the extension direction of the photovoltaic module and drives the pushing head to rotate along the axis of the output shaft of the rotary cylinder.

[0088] The corner cylinder can provide both linear drive along the axis of its output shaft and rotational drive along the axis of its output shaft. For example, Figure 7 and Figure 8 as shown, during the short-side alignment operation, the first driving member 6212 first drives the first pushing head 6213 to rotate to the vertical state so that it can avoid other mechanisms during subsequent movements. Then, the first driving member 6212 linearly drives the first pushing head 6213 to move relative to the frame 1 along the extension direction of the long side of the photovoltaic module to achieve the alignment operation of the short side of the photovoltaic module. During the long-side alignment operation, the second driving member 6222 first drives the second pushing head 6223 to rotate to the vertical state so that it can avoid other mechanisms during subsequent movements. Then, the second driving member 6222 linearly drives the second pushing head 6223 to move relative to the frame 1 along the extension direction of the short side of the photovoltaic module to achieve the alignment operation of the long side of the photovoltaic module, making this mechanism more flexible and improving its practicability.

[0089] Referring to Figure 10 as shown, in an embodiment of the present application, for the leveling mechanism 4, the frame 1 is used to carry the driving assembly 41, the workbench 3 is used to carry the photovoltaic module, and the leveling mechanism 4 includes a driving member 411, a synchronous rod 412, and a plurality of lifting link groups 413. The driving assembly 41 is arranged between the frame 1 and the workbench 3 and is used to provide the power for the workbench 3 to rise or fall. The synchronous rod 412 is connected to the plurality of lifting link groups 413. When the driving member 411 drives the synchronous rod 412 to move, the synchronous rod 412 can drive the plurality of lifting link groups 413 to perform lifting actions synchronously, so that the workbench 3 rises or falls. Compared with the related technology of installing synchronous lifters under the workbench 3 and driving the synchronous lifters by cylinders to achieve the synchronization of the lifting actions of the lifting components, since the structures of the plurality of lifting link groups 413 are the same and they are all connected to the synchronous rod 412 and the workbench 3, therefore, there is no need to adjust the levelness of the connection position between the lifting link group 413 and the workbench 3, and the synchronization of the lifting actions of the lifting link group 413 will not be affected by the levelness adjustment error. The installation is simple, the synchronization of the lifting actions of the lifting link group 413 is good, and the framing quality of the photovoltaic module is high.

[0090] As Figure 10 shown, in the embodiment of the present application, the lifting link group 413 includes a first link 4131 and a second link 4132 fixed together. The first end of the first link 4131 is hinged to the synchronous rod 412, and the second end is hinged to the frame 1; the end of the second link 4132 is hinged to the workbench 3.

[0091] As Figure 12As shown, since the lifting link group 413 needs to generate an upward lifting force under the linear drive of the synchronous rod 412, if the first link 4131 and the second link 4132 of the lifting link group 413 are in a straight line, then the first end of the first link 4131 moves linearly under the linear drive of the synchronous rod 412, and the second end hinged to the frame 1 will generate a rotational force and transmit the rotational force to the end of the second link 4132 connected to the first link 4131, driving the other end of the second link 4132 to move linearly in the opposite direction to the first end of the first link 4131, and the workbench 3 cannot be lifted.

[0092] Therefore, referring to Figure 10 As shown, in this application, the first link 4131 and the second link 4132 fixed together at a certain angle are provided. Under the linear drive of the synchronous rod 412, the first end of the first link 4131 hinged to the synchronous rod 412 is driven to move linearly. The second end of the first link 4131 is hinged to the frame 1. Therefore, the second end of the first link 4131 will generate a clockwise or counterclockwise rotational force and transmit the rotational force to the second link 4132. Through the clockwise or counterclockwise rotation of the second link 4132, the lifting and lowering of the workbench 3 are driven.

[0093] Exemplarily, as Figure 10 shown, the first link 4131 can be directly connected to the frame 1 or connected through a bearing seat. When the first link 4131 is directly connected to the frame 1, a structure for hinging needs to be provided at the corresponding position of the frame 1 as a support point, and then the first link 4131 is hinged to the frame 1, which is inconvenient for installation. In the embodiment of this application, the first link 4131 is connected to the frame 1 through the first bearing seat 4133. With the bearing as the inner support point for the hinge between the first link 4131 and the frame 1 and the first bearing seat 4133 as the outer support point for the hinge between the first link 4131 and the frame 1, the installation is convenient.

[0094] Similarly, referring to Figure 10 , the second link 4132 is connected to the workbench 3 through the second bearing seat 4134, and the same technical effect as that of the aforementioned first bearing seat 4133 can be achieved.

[0095] Referring to Figure 10, the first link 4131 can be connected to one second link 4132 or multiple second links 4132. When the first link 4131 is connected to one second link 4132, a lifting link group 413 can only drive one point of the workbench 3 to rise and fall. Therefore, in the embodiment of the present application, the first link 4131 is connected to two second links 4132. Specifically, the first link 4131 and the second link 4132 are fixed by a first rotating shaft 4135. The first rotating shaft 4135 is connected to one end of two second links 4132, and the other ends of the two second links 4132 are connected by a second rotating shaft 4136. The first rotating shaft 4135 and the second rotating shaft 4136 are arranged in parallel. The first link 4131, the two second links 4132, the first rotating shaft 4135, and the second rotating shaft 4136 form a lifting link group 413. By connecting the first link 4131 to two second links 4132, a lifting link group 413 can synchronously drive two points of the workbench 3 to rise and fall, reducing the number of driving members 411 and synchronizing rods 412 provided, saving costs, and saving space inside the frame 1.

[0096] As Figure 11 shown, if the first rotating shaft 4135 and the second rotating shaft 4136 are not arranged in parallel, the heights of the connection ends of the two second links 4132 and the second rotating shaft 4136 swing up and down differently, so that a lifting link group 413 cannot drive two points of the workbench 3 to rise and fall synchronously, losing the meaning of connecting the first link 4131 to two second links 4132. Therefore, in the embodiment of the present application, the first rotating shaft 4135 and the second rotating shaft 4136 are arranged in parallel, so that the connection ends of the two second links 4132 and the second rotating shaft 4136 can rise and fall synchronously.

[0097] As Figure 11 shown, according to the needs of the actual framing device, the first link 4131 can be connected to more than two second links 4132 through the first rotating shaft 4135.

[0098] Referring to Figure 11 , the two second links 4132 can be arranged on one side of the first link 4131 or on both sides of the first link 4131. When the length of the first rotating shaft 4135 is fixed, when the two second links 4132 are arranged on one side of the first link 4131, the distance between the two second links 4132 is less than the distance when the two second links 4132 are arranged on both sides of the first link 4131, affecting the support width of the two second links 4132 for the workbench 3. Therefore, in the embodiment of the present application, the two second links 4132 are arranged on both sides of the first link 4131, improving the support width of the two second links 4132 for the workbench 3. When the width of the photovoltaic module is large, the number of leveling mechanisms 4 provided can be saved, saving costs.

[0099] Reference Figure 10 and Figure 11 As shown in FIGS. and, the two second linkages 4132 can be arranged at both ends of the first rotating shaft 4135 at intervals along the first rotating shaft 4135, or can be arranged at any positions on both sides of the first linkage 4131. When the two second linkages 4132 are arranged at any positions on both sides of the first linkage 4131, unnecessary ends will appear on the first rotating shaft 4135, affecting the utilization rate of the space inside the frame 1. Therefore, in the embodiments of the present application, the two second linkages 4132 are arranged at both ends of the first rotating shaft 4135, making full use of the length of the first rotating shaft 4135 and using this length as the width of the lifting support point, thus making full use of the space inside the frame 1.

[0100] As Figure 11 and Figure 12 shown, in the embodiments of the present application, the two second linkages 4132 are vertically arranged at both ends of the first rotating shaft 4135. The first rotating shaft 4135, the second rotating shaft 4136 and the two second linkages 4132 form a rectangle, and the rectangular structure can make full use of the space inside the frame 1 and improve the utilization rate of the space inside the frame 1.

[0101] As Figure 11 and Figure 12 shown, the two second linkages 4132 can be symmetrically arranged at both ends of the first rotating shaft 4135, and the first rotating shaft 4135, the second rotating shaft 4136 and the two second linkages 4132 form a trapezoid; the two second linkages 4132 can be parallelly arranged at both ends of the first rotating shaft 4135, and the first rotating shaft 4135, the second rotating shaft 4136 and the two second linkages 4132 form a parallelogram.

[0102] Exemplarily, as Figure 11 and Figure 12 shown, the first linkage 4131 can be arranged at any position between both ends of the first rotating shaft 4135. In order to make the forces at both ends of the first rotating shaft 4135 the same and extend the service life of the entire lifting linkage group 413 and the leveling mechanism 4, in the embodiments of the present application, the first linkage 4131 is arranged in the middle of the first rotating shaft 4135. Since the force arms from the first linkage 4131 to both ends of the first rotating shaft 4135 are the same, the forces at both ends of the first rotating shaft 4135 are the same. Therefore, the wear degrees at both ends of the first rotating shaft 4135 will also be the same, and the service lives will be relatively consistent, avoiding the situation where one end is already damaged while the other end is not yet damaged, and extending the service life of the entire lifting linkage group 413 and the leveling mechanism 4.

[0103] As Figure 11 and Figure 12As shown, the driving member 411 can be fixedly connected to the synchronizing rod 412 or hinged to the synchronizing rod 412. Since the first end of the first link 4131 is hinged to the synchronizing rod 412 and the second end is hinged to the frame 1, when the first link 4131 is subjected to the driving force of the driving member 411, the first link 4131 will rotate around the second end, and the movement path of the second end is arc-shaped. If the driving member 411 is fixedly connected to the synchronizing rod 412, the connection will be severely worn due to the movement of the second end of the first link 4131, affecting the service life of the leveling mechanism 4. Therefore, in the embodiment of the present application, the driving member 411 and the synchronizing rod 412 are hinged through the first joint 414, and the first joint 414 is hinged to the lifting link group 413. When the second end of the first link 4131 moves along its arc-shaped path, the hinged end of the driving member 411 and the synchronizing rod 412 will relieve the wear degree at the connection between the driving member 411 and the synchronizing rod 412, extending the service life of the leveling mechanism 4.

[0104] Further, as Figure 11 shown, the first joint 414 is of a U-shaped structure. Two sets of through holes are correspondingly provided on both sides of the U-shaped structure. Deep groove ball bearings of push rods 4112 are provided in each set of through holes near the opening of the U-shaped structure, and first deep groove ball bearings 4142 are provided in the other set of through holes. A through hole is provided at the first end of the first link 4131. The first end is inserted into the first joint 414, and the first link 4131 is connected to the first joint 414 through the first connecting pin shaft 4141 passing through the through hole at the first end of the first link 4131 and the first deep groove ball bearing 4142. The wear at the connection between the first link 4131 and the first joint 414 is reduced through the connecting pin shaft and the deep groove ball bearing, improving the service life of the leveling mechanism 4.

[0105] Meanwhile, referring to Figure 11 , the first joint 414 is connected to one end of the synchronizing rod 412 through the first locking nut 4143. The other end of the synchronizing rod 412 is connected to the second joint 415 through the second locking nut 4153. The second joint 415 is connected to the lifting link group 413 through the second connecting pin shaft 4151 and the second deep groove ball bearing 4152. Through the movement of the synchronizing rod 412, the synchronous lifting of the two lifting link groups 413 is driven.

[0106] Referring to Figure 10 , two or more second joints 415 can be provided on the synchronizing rod 412, and each second joint 415 is connected to the lifting link group 413. Through the movement of the synchronizing rod 412, the synchronous lifting of all the lifting link groups 413 is driven.

[0107] Referring to Figure 10, the driving member 411 can be powered by a cylinder or a motor. When powered by a cylinder, due to the single stroke of the cylinder, when producing photovoltaic modules of different specifications, only the position of the floating joint of the cylinder can be adjusted to finely adjust the lifting height of the workbench 3, and the adjustment amount is limited, which affects the production efficiency of photovoltaic modules of different specifications. Therefore, in the embodiment of the present application, a servo motor is used to provide power. Specifically, the driving member 411 includes a linear motor 4111. The output end of the linear motor 4111 is connected to one end of a push rod 4112, and the other end of the push rod 4112 is connected to a synchronizing rod 412. When producing photovoltaic modules of different specifications, the linear motor 4111 controls the lifting height of the lifting link group 413 by controlling the action stroke of the push rod 4112, without the need to stop the machine for manual adjustment, improving the production efficiency of photovoltaic modules of different specifications. At the same time, the use of the linear motor 4111 also improves the accuracy of the lifting action of the lifting link group 413.

[0108] As Figure 11 and 12 shown, specifically, one end of the push rod 4112 is connected to the first joint 414 through a push rod joint 4113. The push rod 4112 is threadedly connected to the push rod joint 4113. The push rod joint 4113 is of a T-shaped structure. One end of the push rod joint 4113 extends into the first joint 414. A through hole is provided at the end extending into the first joint 414. A push rod connecting pin shaft 4144 passes through the through hole and a deep groove ball bearing 4145 of the push rod to connect the push rod joint 4113 with the first joint 414; the other end of the push rod 4112 is fixed to the frame 1 through a hinge base 4114. Fixing the push rod 4112 to the frame 1 improves the stability of the driving member 411. Hinging with the frame 1 and the first joint 414 can relieve the wear at the connection between the frame 1 and the push rod 4112 and the connection between the push rod 4112 and the first joint 414, and improve the service life of the driving member 411.

[0109] As Figure 12 and Figure 13 shown, in order to reduce the load on the linear motor 4111 and improve the service life of the leveling mechanism 4, in the embodiment of the present application, a boosting lifting cylinder 4164 assembly 416 is further provided between the frame 1 and the workbench 3. The boosting lifting cylinder 4164 assembly 416 is arranged at the four corners of the workbench 3. During the rising and falling process of the lifting link group 413, it moves synchronously with the linear motor 4111, reducing the load on the linear motor 4111, improving the service life of the leveling mechanism 4, and at the same time compensating for the thread clearance of the push rod 4112 and improving the stability of the lifting action.

[0110] As Figure 13As shown in the figure, specifically, the assisting lifting cylinder 4164 assembly 416 includes an assisting lifting cylinder 4164. The assisting lifting cylinder 4164 is connected to the frame 1 through a cylinder hinge base 4161 at the lower part, and is connected to a lifting connection seat 4163 arranged on the workbench 3 through a Y-shaped joint 4162 at the upper part.

[0111] The photovoltaic module positioning mechanism provided by the embodiment of the present application is referred to Figure 15 and Figure 16 As shown, it includes a first suction cup assembly 501 and N auxiliary suction cup assemblies (refer to Figure 16 the label, the second suction cup assembly 502 and the third suction cup assembly 505, which is an embodiment thereof). Among them, the first suction cup assembly 501 is used to adsorb the photovoltaic module, and the first suction cup assembly 501 is arranged on the frame 1; N is a positive integer greater than or equal to one. The adsorption direction of the auxiliary suction cup assembly is the same as that of the first suction cup assembly 501. The auxiliary suction cup assembly is movably connected to the frame 1. The auxiliary suction cup assembly can move to a first height position and a second height position. The height direction is opposite to the adsorption direction of the auxiliary suction cup assembly. When the auxiliary suction cup assembly is in the first height position, the auxiliary suction cup assembly is lower than the first suction cup assembly 501. When the auxiliary suction cup assembly is in the second height position, the auxiliary suction cup assembly is flush with the first suction cup assembly 501. When the auxiliary suction cup assembly is flush with the first suction cup assembly 501, the auxiliary suction cup assembly and the first suction cup assembly are arranged in the vertical direction of the height direction. During the process of adsorbing a photovoltaic module with a smaller area, the auxiliary suction cup assembly does not work. During the process of adsorbing a photovoltaic module with a larger area, the first suction cup assembly 501 and the auxiliary suction cup assembly work simultaneously. Compared with the related technology where the number of suction cups for adsorbing a photovoltaic module with a larger area is the same as that for adsorbing a photovoltaic module with a smaller area, it is beneficial to save resources and control the adsorption force; when the auxiliary suction cup assembly is flush with the first suction cup assembly 501, the spacing distance between the auxiliary suction cup assembly and the first suction cup assembly arranged in the vertical direction of the height direction can be conveniently set according to the area size of the photovoltaic module, avoiding the problem in the related technology that the distance between the fixed suction cup and the movable suction cup becomes larger after the movable suction cup extends outwards, resulting in poor flatness of a larger photovoltaic module; the movement of the auxiliary suction cup assembly changes the distance between the first suction cup assembly 501 and the auxiliary suction cup assembly in the height direction. Compared with the related technology where the movement of the movable suction cup changes the distance between the movable suction cup and the fixed suction cup in the vertical direction of the height direction, it is beneficial to save space.

[0112] As Figure 16 shown, it should be noted that the framing machine frames the photovoltaic module along the adsorption direction. When the framing machine frames the photovoltaic module independently adsorbed by the first suction cup assembly 501, the auxiliary suction cup assembly is in the first height position to avoid the framing machine and prevent the framing machine from hitting the auxiliary suction cup assembly.

[0113] In some embodiments, please refer to Figure 15 and Figure 16 , when the N auxiliary suction cup assemblies are flush with the first suction cup assembly 501, the N auxiliary suction cup assemblies and the first suction cup assembly 501 are arranged in a straight line. In such a structural form, the distances between the N auxiliary suction cup assemblies and the first suction cup assembly 501 are different. The auxiliary suction cup assembly, the first suction cup assembly 501, and the auxiliary suction cup assemblies between this auxiliary suction cup assembly and the first suction cup assembly 501 with a larger distance from the first suction cup assembly 501 can jointly adsorb a photovoltaic module with a larger area. The auxiliary suction cup assembly, the first suction cup assembly 501, and the auxiliary suction cup assemblies between this suction cup assembly and the first suction cup assembly 501 with a smaller distance from the first suction cup assembly 501 can jointly adsorb a photovoltaic module with a smaller area. Thus, the photovoltaic module positioning mechanism 5 can adapt to various specifications of photovoltaic modules.

[0114] In some embodiments, refer to Figure 14 and Figure 15 As shown, the photovoltaic module positioning mechanism further includes an auxiliary suction cup assembly driving mechanism 503, and the auxiliary suction cup assembly driving mechanism 503 is arranged on the frame 1. The auxiliary suction cup assembly driving mechanism 503 is used to drive the auxiliary suction cup assembly to move between a first height position and a second height position. The auxiliary suction cup assembly driving mechanism 503 can be implemented in various ways. For example, it can be a power cylinder, a linear motor, a lead screw nut, a link mechanism, a rack and pinion, and a worm and worm gear, etc. In the embodiment of the present application, the auxiliary suction cup assembly driving mechanism 503 is a power cylinder. The cylinder body of the power cylinder is fixed to the frame 1, and the piston rod is fixed to the auxiliary suction cup assembly. On this basis, in some embodiments, the telescopic direction of the piston rod of the air cylinder is parallel to the height direction.

[0115] In some embodiments, refer to Figure 14 and Figure 15As shown, the first suction cup assembly 501 includes a first suction cup 5011 and a first pre - suction cup 5012. The first pre - suction cup 5012 can move to a second height position and a third height position. When the first pre - suction cup 5012 moves to the third height position, the first suction cup 5011 is lower than the first pre - suction cup 5012. When the first pre - suction cup 5012 moves to the second height position, the first suction cup 5011 is flush with the first pre - suction cup 5012. When the first suction cup 5011 is flush with the first pre - suction cup 5012, the first suction cup 5011 and the first pre - suction cup 5012 can jointly adsorb the photovoltaic module. When the first suction cup 5011 is lower than the first pre - suction cup 5012, there is a spacing between the first suction cup 5011 and the first pre - suction cup 5012 in the adsorption direction. When the first pre - suction cup 5012 adsorbs the photovoltaic module, there is a spacing between the first suction cup 5011 and the photovoltaic module. Specifically, during the process of the first suction cup assembly 501 adsorbing the photovoltaic module, the photovoltaic module is first adsorbed on the first pre - suction cup 5012, and then jointly adsorbed by the first pre - suction cup 5012 and the first suction cup 5011. That is, the first suction cup assembly 501 adsorbs the photovoltaic module in two steps, which can make the positioning mechanism of the photovoltaic module more accurate.

[0116] It should be noted that, referring to Figure 14 and Figure 15 shown, the adsorption direction of the first suction cup 5011 and the adsorption direction of the first pre - suction cup 5012, that is, the adsorption direction of the first suction cup assembly 501. Both the first suction cup 5011 and the first pre - suction cup 5012 are used to adsorb the photovoltaic module. In some embodiments, both the first suction cup 5011 and the second suction cup 5021 are vacuum suction cups.

[0117] It can be understood that, referring to Figure 14 and Figure 15 shown, for the first pre - suction cup 5012 moving to the second height position and the third height position, the moving direction of the first pre - suction cup 5012 can be any direction not perpendicular to the height direction, that is, there is an angle between the moving direction of the first pre - suction cup 5012 and the perpendicular direction of the height direction.

[0118] In some embodiments, such as Figure 14 and Figure 15 , the photovoltaic module corresponding to the size of the first suction cup assembly 501 is the first battery module. The number of the first pre - suction cups 5012 is four, and the four first pre - suction cups 5012 are respectively used to adsorb the four corners of the first battery module. During the process of the first suction cup assembly 501 adsorbing the first battery module, the four corners of the first battery module can be positioned first to ensure the accuracy of the four corners of the first battery module. During the process of installing the frame of the photovoltaic module, the accuracy of the four - corner positions of the photovoltaic module is more important than the accuracy of other positions. Therefore, positioning the four corners of the photovoltaic module first can better ensure the position accuracy of the photovoltaic module.

[0119] It should be noted that, generally, the photovoltaic module has a rectangular plate-like structure. Referring to Figure 14 , the above four first pre-suction cups 5012 are respectively used to adsorb the four corners of the first battery module, which means that the four first pre-suction cups 5012 are respectively used to adsorb the four corners of the plate surface of the first battery module having a rectangular plate-like structure.

[0120] Of course, in some other embodiments, as Figure 14 shown, the first battery module may not have a rectangular structure. The first battery module may be a plate-like structure in the shape of a triangle or other polygons, and the number of the first pre-suction cups 5012 is not four. The number of the first pre-suction cups 5012 is the same as the number of sides of the above triangular or other polygon plate-like structure, and multiple first pre-suction cups 5012 are respectively used to adsorb the corresponding corners of the plate-like structure in the shape of a triangle or other polygons.

[0121] In some specific embodiments, referring to Figure 14 and Figure 15 shown, the positioning mechanism further includes a driving mechanism for the first pre-suction cup 5012. The driving mechanism for the first pre-suction cup 5012 is arranged on the frame 1. The driving mechanism for the first pre-suction cup 5012 is used to drive the first pre-suction cup 5012 to move between the second height position and the third height position. The driving mechanism 503 for the second suction cup assembly can be implemented in various ways. For example, it can be a power cylinder, a linear motor, a lead screw nut, a link mechanism, a gear rack, and a worm and worm gear, etc. In the embodiment of the present application, the driving mechanism for the first pre-suction cup 5012 is a power cylinder. The cylinder body of the power cylinder is fixed to the frame 1, and the piston rod is fixed to the second suction cup assembly 502. On this basis, in some embodiments, the telescopic direction of the piston rod of the air cylinder is parallel to the height direction.

[0122] In the embodiment of the present application, please refer to Figure 14 and Figure 15, the first suction cup assembly 501 adsorbs the photovoltaic module in two steps through the first pre-suction cup 5012 and the first suction cup 5011. In some other embodiments, the first suction cup assembly 501 can also adsorb the photovoltaic module in more than two steps. In this way, the positioning of the photovoltaic module by the photovoltaic module positioning mechanism 5 can be made more accurate. In some embodiments, the first suction cup assembly includes a static suction cup group and M moving suction cup groups, where M is a positive integer greater than or equal to one. The static suction cup group is located at the second height position, and the M moving suction cup groups can move from the second height position to M height positions respectively, and all M height positions are higher than the second height position. Specifically, during the process of the first suction cup assembly 501 adsorbing the photovoltaic module, the moving suction cup group that can move to a higher height position adsorbs the photovoltaic module first, and then the moving suction cup group adsorbs the photovoltaic module and moves it towards the second height position. During the movement, the moving suction cup group that can move to a lower height position will meet and adsorb the photovoltaic module. Then, the moving suction cup group that can move to a higher height position and the moving suction cup group that can move to a lower height position move towards the second height position together. Finally, all the moving suction cup groups descend to the second height position, and the static suction cup group is flush with the moving suction cup groups to jointly adsorb the photovoltaic module.

[0123] Further, as Figure 14 and Figure 15 shown, the N auxiliary suction cup assemblies include a second suction cup assembly 502. Among them, the second suction cup assembly 502 includes a second suction cup 5021 and a second pre-suction cup 5022. When the second suction cup assembly 502 moves to the second height position, the second pre-suction cup 5022 can move to the second height position and the third height position. When the second pre-suction cup 5022 moves to the third height position, the second suction cup 5021 is lower than the second pre-suction cup 5022. When the second pre-suction cup 5022 moves to the second height position, the second suction cup 5021 is flush with the second pre-suction cup 5022. The second suction cup 5021 and the second pre-suction cup 5022 can jointly adsorb the photovoltaic module. When the second suction cup 5021 is lower than the second pre-suction cup 5022, there is a distance between the second suction cup 5021 and the second pre-suction cup 5022 in the adsorption direction. When the second pre-suction cup 5022 adsorbs the photovoltaic module, there is a distance between the second suction cup 5021 and the photovoltaic module. Specifically, during the process of the second suction cup assembly 502 adsorbing the photovoltaic module, the photovoltaic module is first adsorbed on the second pre-suction cup 5022, and then jointly adsorbed by the second pre-suction cup 5022 and the second suction cup 5021, that is, the second suction cup assembly 502 adsorbs the photovoltaic module in two steps, which can make the positioning of the positioning mechanism for the photovoltaic module more accurate.

[0124] It should be noted that, as Figure 14As shown, the adsorption direction of the second suction cup 5021 and the adsorption direction of the second pre-suction cup 5022, which is the adsorption direction of the second suction cup assembly 502. Both the second suction cup 5021 and the second pre-suction cup 5022 are used to adsorb the photovoltaic module. In some embodiments, both the second suction cup 5021 and the second suction cup 5021 are vacuum suction cups.

[0125] As Figure 14 and Figure 15 shown, when the second suction cup assembly 502 moves to the second height position, the second pre-suction cup 5022 can move to the second height position and the third height position. In some embodiments, the second suction cup assembly 502 further includes a first carrier 5023. The first carrier 5023 is connected to the output end of the second suction cup assembly driving mechanism 503. Both the second suction cup 5021 and the second pre-suction cup 5022 are arranged on the first carrier 5023. The second suction cup assembly driving mechanism 503 is used to drive the first carrier 5023 to move so that the second suction cup 5021 and the second pre-suction cup 5022 move to the first height position and the second height position. On this basis, the second suction cup assembly 502 further includes a second pre-suction cup driving mechanism 5024. The second pre-suction cup driving mechanism 5024 is arranged on the first carrier 5023. The second pre-suction cup 5022 is connected to the output end of the second pre-suction cup driving mechanism 5024. The second pre-suction cup driving mechanism 5024 is used to drive the second pre-suction cup 5022 to move to the second height position and the third height position. The second pre-suction cup driving mechanism 5024 can have various implementation manners. For example, it can be a power cylinder, a linear motor, a lead screw nut, a link mechanism, a rack and pinion, and a worm and worm gear, etc. In the embodiment of the present application, the second pre-suction cup driving mechanism 5024 is a power cylinder. The cylinder body of the power cylinder is fixed to the first carrier 5023, and the piston rod is fixed to the second pre-suction cup 5022. On this basis, in some embodiments, the telescopic direction of the piston rod of the cylinder is parallel to the height direction.

[0126] In some embodiments, referring to Figure 15 shown, the positioning mechanism further includes a first guiding assembly 504. The first guiding assembly 504 includes a first fixing member 5041 and a first moving member 5042. The first fixing member 5041 is arranged on the frame 1, and the first moving member 5042 is arranged on the first carrier 5023. The first fixing member 5041 and the first moving member 5042 are slidably connected, and the moving direction of the first moving member 5042 relative to the first moving member 5042 is parallel to the height direction. On this basis, in some embodiments, the first fixing member 5041 is a guiding cylinder, and the first moving member 5042 is a guiding rod. The guiding rod is slidably inserted into the guiding cylinder.

[0127] In some other embodiments, referring to Figure 14 and Figure 15As shown, the second suction cup assembly 502 may not include the first carrier 5023. The second suction cup assembly 502 is composed of a second suction cup 5021, a second pre-suction cup 5022, a driving mechanism for the second suction cup 5021, and a driving mechanism for the second pre-suction cup 5024. The driving mechanism for the second suction cup 5021 and the driving mechanism for the second pre-suction cup 5024 are both arranged on the frame 1. The driving mechanism for the second suction cup 5021 is used to drive the second suction cup 5021 to move to the first height position and the second height position, and the driving mechanism for the second pre-suction cup 5024 is used to drive the second pre-suction cup 5022 to move to the first height position, the second height position, and the third height position

[0128] It should be noted that, referring to Figure 16 As shown, second suction cup assemblies 502 are arranged on both opposite sides of the first suction cup assembly 501. For a photovoltaic module in the shape of a rectangular plate, the first suction cup assembly 501 and the two second suction cup assemblies 502 can jointly and stably adsorb the photovoltaic module, enabling the positioning mechanism to accurately position the photovoltaic module.

[0129] Furthermore, as Figure 14 and Figure 16 shown, the photovoltaic module corresponding to the area formed by the second suction cup assemblies 502 on both sides is the second battery module; each second suction cup assembly 502 has two second pre-suction cups 5022, and the four second pre-suction cups 5022 on the second suction cup assemblies 502 on both sides are respectively used to adsorb the four corners of the second battery module. During the adsorption process of the second suction cup assembly 502 to the second battery module, the four corners of the second battery module can be positioned first to ensure the accuracy of the four corners of the second battery module.

[0130] Specifically, referring to Figure 14 and Figure 15 shown. During the adsorption process of the positioning mechanism to the second battery module, first, the second pre-suction cup 5022 is in the third height position to adsorb the second battery module. At this time, the first suction cup 5011, the first pre-suction cup 5012, and the second suction cup 5021 are all in the second height position. Then, the second pre-suction cup 5022 adsorbs the second battery module and moves to the second height position. Finally, the first suction cup 5011, the first pre-suction cup 5012, the second suction cup 5021, and the second pre-suction cup 5022 jointly adsorb the second battery module.

[0131] In the embodiment of the present application, the second suction cup assembly 502 adsorbs the photovoltaic module in two steps through the first pre-suction cup 5012 and the second suction cup 5021. In some other embodiments, the second suction cup assembly 502 can also adsorb the photovoltaic module in more than two steps. In this way, the positioning of the photovoltaic module by the photovoltaic module positioning mechanism 5 can be made more accurate. In some embodiments, the auxiliary suction cup assembly includes an auxiliary static suction cup group and L auxiliary moving suction cup groups, where L is a positive integer greater than or equal to one. When the auxiliary suction cup assembly moves to the second height position, the auxiliary static suction cup group is located at the second height position, and the L auxiliary moving suction cup groups can respectively move from the second height position to L height positions, and the L height positions are all higher than the second height position. Specifically, during the process of the second suction cup assembly 502 adsorbing the photovoltaic module, the auxiliary moving suction cup group that can move to a higher height position first adsorbs the photovoltaic module, and then the auxiliary moving suction cup group adsorbs the photovoltaic module and moves it towards the second height position. During the movement, the auxiliary moving suction cup group that can move to a lower height position will meet and adsorb the photovoltaic module. Then, the auxiliary moving suction cup group that can move to a higher height position and the auxiliary moving suction cup group that can move to a lower height position move towards the second height position together. Finally, all the auxiliary moving suction cup groups descend to the second height position, and the auxiliary static suction cup group is flush with the auxiliary moving suction cup groups to jointly adsorb the photovoltaic module.

[0132] Specifically, as Figure 14 and Figure 15 shown, the N auxiliary suction cup assemblies further include a third suction cup assembly 505. The third suction cup assembly 505 includes a third suction cup 5051 and a third pre-suction cup 5052. When the third suction cup assembly 505 moves to the second height position, the third pre-suction cup 5052 can move to the second height position and the third height position. When the third pre-suction cup 5052 moves to the third height position, the third suction cup 5051 is lower than the third pre-suction cup 5052. When the third pre-suction cup 5052 moves to the second height position, the third suction cup 5051 is flush with the third pre-suction cup 5052. In such a structural form, when the third suction cup 5051 is flush with the third pre-suction cup 5052, the third suction cup 5051 and the third pre-suction cup 5052 can jointly adsorb the photovoltaic module. When the third suction cup 5051 is lower than the third pre-suction cup 5052, there is a distance between the third suction cup 5051 and the third pre-suction cup 5052 in the adsorption direction. When the third pre-suction cup 5052 adsorbs the photovoltaic module, there is a distance between the third suction cup 5051 and the photovoltaic module. Specifically, during the process of the third suction cup assembly 505 adsorbing the photovoltaic module, the photovoltaic module is first adsorbed on the third pre-suction cup 5052, and then jointly adsorbed by the third pre-suction cup 5052 and the third suction cup 5051, that is, the third suction cup assembly 505 adsorbs the photovoltaic module in two steps, which can make the positioning of the positioning mechanism for the photovoltaic module more accurate.

[0133] As shown in Figure 14 and Figure 15 When the third suction cup assembly 505 moves to the second height position, the third pre-suction cup 5052 can move to the second height position and the third height position. In some embodiments, the third suction cup assembly 505 further includes a second carrier 5053. The second carrier 5053 is connected to the output end of the third suction cup assembly driving mechanism 506. The third suction cup 5051 and the third pre-suction cup 5052 are both arranged on the second carrier 5053. The third suction cup assembly driving mechanism 506 is used to drive the second carrier 5053 to move so that the third suction cup 5051 and the third pre-suction cup 5052 move to the first height position and the second height position. On this basis, the third suction cup assembly 505 further includes a third pre-suction cup driving mechanism 5054. The third pre-suction cup driving mechanism 5054 is arranged on the second carrier 5053. The third pre-suction cup 5052 is connected to the output end of the third pre-suction cup driving mechanism 5054. The third pre-suction cup driving mechanism 5054 is used to drive the third pre-suction cup 5052 to move to the second height position and the third height position. The third pre-suction cup driving mechanism 5054 can be implemented in various ways. For example, it can be a power cylinder, a linear motor, a lead screw nut, a link mechanism, a rack and pinion, and a worm and worm gear, etc. In the embodiment of the present application, the third pre-suction cup driving mechanism 5054 is a power cylinder. The cylinder body of the power cylinder is fixed to the second carrier 5053, and the piston rod is fixed to the third pre-suction cup 5052. On this basis, in some embodiments, the telescopic direction of the piston rod of the cylinder is parallel to the height direction.

[0134] In some embodiments, referring to Figure 15 , the positioning mechanism further includes a second guiding component 507. The second guiding component 507 includes a second fixing member 5071 and a second moving member 5072. The second fixing member 5071 is arranged on the frame 1, and the second moving member 5072 is arranged on the second carrier 5053. The second fixing member 5071 and the second moving member 5072 are slidably connected, and the moving direction of the second moving member 5072 relative to the second moving member 5072 is parallel to the height direction. On this basis, in some embodiments, the second fixing member 5071 is a guiding cylinder, and the second moving member 5072 is a guiding rod. The guiding rod is slidably inserted into the guiding cylinder.

[0135] In some other embodiments, as shown in Figure 14 and Figure 15As shown, the third suction cup assembly 505 may not include the second carrier 5053. The third suction cup assembly 505 is composed of a third suction cup 5051, a third pre-suction cup 5052, a driving mechanism for the third suction cup 5051, and a driving mechanism for the third pre-suction cup 5054. The driving mechanism for the third suction cup 5051 and the driving mechanism for the third pre-suction cup 5054 are both arranged on the frame 1. The driving mechanism for the third suction cup 5051 is used to drive the third suction cup 5051 to move to the first height position and the second height position, and the driving mechanism for the third pre-suction cup 5054 is used to drive the third pre-suction cup 5052 to move to the first height position, the second height position, and the third height position.

[0136] Further, referring to Figure 15 , third suction cup assemblies 505 are arranged on both opposite sides of the first suction cup assembly 501, and the first suction cup assembly 501, the second suction cup assembly 502, and the third suction cup assemblies 505 are arranged in a straight line. In such a structural form, for a photovoltaic module in the shape of a rectangular plate, the first suction cup assembly 501 and the two third suction cup assemblies 505 can jointly and stably adsorb the photovoltaic module, making the positioning of the photovoltaic module by the positioning mechanism more accurate. On this basis, in some embodiments, the third suction cup assemblies 505 on both sides are symmetrically distributed relative to the first suction cup assembly 501.

[0137] It should be added that, referring to Figure 14 and Figure 16 , the four second pre-suction cups 5022 on the second suction cup assemblies 502 on both sides are arranged in a rectangle, and the rectangle surrounded by the four second pre-suction cups 5022 is called the first rectangle. The four third pre-suction cups 5052 on the third suction cup assemblies 505 on both sides are arranged in a rectangle, and the rectangle surrounded by the four third pre-suction cups 5052 is called the second rectangle. When the positioning mechanism adsorbs the third battery module, the first pre-suction cup 5012, the second pre-suction cups 5022, the third suction cup 5051, and the third pre-suction cups 5052 are all in the open state, the second suction cups 5021 and the first suction cups 5011 located within the contour line of the second rectangle are in the closed state, and the first suction cups 5011 located on the contour line of the second rectangle are in the open state.

[0138] Specifically, in some embodiments, such as Figure 14As shown, the first pre-suction cup 5012, the second suction cup 5021, the second pre-suction cup 5022, the second suction cup 5021, the third pre-suction cup 5052 and the third suction cup 5051 are all vacuum suction cups.
