DETAILED DESCRIPTION

[0038] The following is a further detailed description of the embodiments of the present disclosure in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present disclosure, but are not intended to limit the scope of the present disclosure.

Therefore, it should not be understood as limiting the embodiments of the present disclosure. In addition, the terms "first," "second," and "third" are used for descriptive purposes and should not be understood to indicate or imply relative importance.

For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0041] In the description of this specification, reference to the terms "some embodiments," "example," etc., means that the features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0042] With the rapid development of photovoltaic power generation, the demand for photovoltaic modules is increasing. Currently, photovoltaic modules are produced using automated production lines. However, the conveying equipment on photovoltaic module production lines usually transports photovoltaic modules in a single direction, making it difficult to change the placement of photovoltaic modules on the conveying equipment, resulting in low production efficiency.

[0043] Referring to Figures 1 to 3, an embodiment of the present disclosure provides a rotary lifting device 100, comprising a rotary mechanism 10 and a pallet 30. The rotary mechanism 10 comprises a connecting shaft 11, a rotary shaft 12, a rotary drive member 13, and a clutch 14. The connecting shaft 11 is respectively connected to the rotary drive member 13 and the clutch 14, and the connecting shaft 11 is configured to transmit power to the clutch 14; the rotary shaft 12 is respectively connected to the clutch 14 and the pallet 30, and the rotary shaft 12 is configured to transmit power to the pallet 30; when the clutch 14 is in an engaged state, the power transmitted from the connecting shaft 11 to the clutch 14 is transmitted to the rotary shaft 12; when the clutch 14 is in a disengaged state, the power transmitted from the connecting shaft 11 to the clutch 14 is cut off from transmission relative to the rotary shaft 12. The rotary drive member 13 is configured to provide power. In other words, clutch 14 can connect rotating shaft 12 and connecting shaft 11 into a single unit, so that the rotating drive member 13 drives connecting shaft 11, causing clutch 14 and rotating shaft 12 to rotate synchronously. Clutch 14 can also separate rotating shaft 12 from connecting shaft 11, preventing rotating shaft 12 from rotating with clutch 14 and connecting shaft 11. Tray 30 is connected to rotating shaft 12. Tray 30 is configured to carry objects, such as photovoltaic modules.

[0044] Taking the tray 30 carrying photovoltaic modules as an example, the working principle of the rotating mechanism 10 is described as follows: when the placement direction of the photovoltaic modules needs to be changed, the clutch 14 engages the rotating shaft 12 and the connecting shaft 11, the rotating drive 13 drives the connecting shaft 11 to rotate, the connecting shaft 11 drives the clutch 14 and the rotating shaft 12 to rotate, and the rotating shaft 12 drives the tray 30 carrying the photovoltaic modules to rotate, so that the photovoltaic modules can be rotated in the forward direction, thereby changing the placement direction of the photovoltaic modules. After the above-mentioned rotation operation is completed, the clutch 14 can separate the rotating shaft 12 and the connecting shaft 11, that is, the clutch 14 disconnects the rotating shaft 12 and the connecting shaft 11, so that the rotating drive 13 no longer drives the rotating shaft 12 and the tray 30 to rotate. When the photovoltaic modules need to continue to rotate in the forward direction or the placement direction of the next batch of photovoltaic modules needs to be changed, the clutch 14 reengages the rotating shaft 12 and the connecting shaft 11, so that the photovoltaic modules can continue to rotate in the forward direction or complete the change of the placement direction of the next batch of photovoltaic modules.

[0045] It should be noted that the positive direction may be clockwise or counterclockwise. Down refers to the direction toward the ground, and up refers to the direction opposite to down.

[0046] In some embodiments, the rotary jacking device 100 further includes a fixed mounting frame 60 and a lifting mechanism 20. The lifting mechanism 20 is connected to the fixed mounting frame 60 and is configured to drive the tray 30 and the rotary mechanism 10 away from or close to the fixed mounting frame 60.

[0047] Taking the tray 30 carrying the photovoltaic module as an example, the working principle of the rotary lifting device 100 is explained as follows: when it is necessary to change the placement direction of the photovoltaic module, the clutch 14 engages the rotating shaft 12 and the connecting shaft 11, and the lifting mechanism 20 drives the rotating mechanism 10 and the tray 30 to move away from the fixed mounting frame 60, for example, upward movement, and the rotary drive member 13 drives the connecting shaft 11 to rotate, and the connecting shaft 11 drives the clutch 14 and the rotating shaft 12 to rotate, and the rotating shaft 12 drives the tray 30 carrying the photovoltaic module to rotate, so that the photovoltaic module can be rotated in the forward direction, so that the placement direction of the photovoltaic module can be changed. After the above-mentioned rotation operation is completed, the clutch 14 can separate the rotating shaft 12 and the connecting shaft 11, that is, the clutch 14 disconnects the rotating shaft 12 and the connecting shaft 11, so that the rotary drive member 13 no longer drives the rotating shaft 12 and the tray 30 to rotate. If the photovoltaic modules need to continue rotating in the forward direction or change the placement direction of the next batch of photovoltaic modules, the clutch 14 re-engages the rotating shaft 12 and the connecting shaft 11, thereby enabling the photovoltaic modules to continue rotating in the forward direction or change the placement direction of the next batch of photovoltaic modules. After the photovoltaic modules are rotated, the lifting mechanism 20 drives the rotating mechanism 10 and the tray 30 to move toward the fixed mounting frame 60, for example, downward, so that the photovoltaic modules can continue to be transported.

[0048] It should be noted that down refers to the direction toward the ground, up refers to the direction opposite to down, and up and down directions refer to directions approaching or moving away from the ground.

[0049] In some embodiments, the lifting mechanism 20 includes a lifting frame 21 and a lifting drive 22. The rotating mechanism 10 is mounted on the lifting frame 21, and the lifting drive 22 is configured to drive the lifting frame 21 to move vertically. The lifting drive 22 is configured to provide power. In other words, the lifting drive 22 can drive the rotating mechanism 10 to move up and down synchronously with the lifting frame 21.

[0050] In some embodiments, to reduce the impact on photovoltaic modules, the lifting drive 22 and the rotating drive 13 can work sequentially. The lifting drive 22 first drives the lifting frame 21 to drive the rotating mechanism 10 to move upward, and the rotating drive 13 then drives the tray 30 to rotate.

[0051] In the rotary lifting device 100 provided by the disclosed embodiment, when the placement direction of the photovoltaic module needs to be changed, the lifting drive 22 drives the lifting frame 21 to move the rotating mechanism 10 and the tray 30 upward, thereby reducing the possibility of damage to the photovoltaic module due to contact with other structural components. After the photovoltaic module is turned, the lifting drive 22 drives the lifting frame 21 to move the rotating mechanism 10 and the tray 30 downward, so that the photovoltaic module can continue to be transported. Under the action of the clutch 14, the rotating mechanism 10 can drive the tray 30 to drive the photovoltaic module to rotate continuously in the same direction, such as the forward direction, thereby improving production efficiency.

[0052] The rotary drive member 13 can be a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0053] In the related art, a motor is used to power the tray's rotation. For example, a motor drives the tray 30 to rotate. However, when the motor is running, position deviations can easily occur, leading to inaccurate positioning. In view of this, in some embodiments, as shown in Figures 2-3 , the rotation driver 13 includes a first cylinder 131, which is configured to drive the connecting shaft 11 to rotate.

[0054] By controlling the first cylinder 131 to drive the connecting shaft 11 , accurate and stable position control can be provided, positioning accuracy can be improved, and rotation speed can be increased.

[0055] For example, referring to Figures 3-4 , the first cylinder 131 includes a first cylinder barrel 1311 and a first piston rod 1312. The first piston rod 1312 extends and retracts horizontally. The first piston rod 1312 is connected to the connecting shaft 11 via a steering member, which converts the linear motion of the first piston rod 1312 into rotation of the connecting shaft 11. By controlling the stroke of the first piston rod 1312, the rotation angle of the photovoltaic module can be controlled, thereby improving rotation accuracy.

[0056] 2-4 , the rotating mechanism 10 further includes a first connecting plate 17, which is fixed to the lifting frame 21, and a first cylinder 1311 is fixed to the first connecting plate 17. In this way, the first cylinder 131 is fixed to the lifting frame 21 and rises or descends with the lifting frame 21.

[0057] 3 , the rotating mechanism 10 includes a rotating universal joint 15 , and the first piston rod 1312 is connected to the connecting shaft 11 via the rotating universal joint 15 . The first cylinder 1311 may be connected to the lifting frame 21 .

[0058] One end of the rotary universal joint 15 is connected to the first piston rod 1312, and the other end is connected to the connecting shaft 11, driving the connecting shaft 11 to rotate. The rotary universal joint 15 converts the linear motion of the first piston rod 1312 into the rotational motion of the connecting shaft 11.

[0059] Exemplarily, the connecting shaft 11 extends in the up-down direction, and one end of the rotary universal joint 15 connected to the connecting shaft 11 is located in the middle position of the connecting shaft 11 in the up-down direction.

[0060] In some embodiments, referring to FIG. 3 and FIG. 5 , the connecting shaft 11 extends in the up-down direction, a connecting platform 141 is formed on the circumferential surface of the clutch 14 , and the connecting shaft 11 is connected to the connecting platform 141 .

[0061] In some embodiments, referring to FIG. 3 , the rotating mechanism 10 includes a reinforcing fixing plate 16 , which connects the connecting shaft 11 and the clutch 14 .

[0062] In this embodiment, the connection strength between the connecting shaft 11 and the clutch 14 can be improved by strengthening the fixing plate 16 , thereby reducing the possibility of bending or breaking of the connecting shaft 11 .

[0063] Exemplarily, the bottom end of the connecting shaft 11 is lower than the lower surface of the clutch 14, and the reinforcing fixing plate 16 includes an inclined plate and two parallel plates of different heights, one of which is connected to the lower surface of the clutch 14, and the other parallel plate is connected to the lower end of the connecting shaft 11, and the inclined plate connects the two parallel plates.

[0064] In some embodiments, as shown in Figures 3 and 5 , the rotary jacking device 100 includes a buffer 40. A limiting protrusion 142 is formed on the circumferential surface of the clutch 14, and the anti-collision head 43 of the buffer 40 is located along the rotational trajectory of the limiting protrusion 142. For example, the buffer 40 is mounted on the lifting frame 21. That is, after the limiting protrusion 142 rotates a predetermined angle, the limiting protrusion 142 can contact the anti-collision head 43 of the buffer 40. The buffer 40 can reduce the vibration and noise caused by the rotary drive member 13 driving the connecting shaft 11.

[0065] For example, referring to FIG3 , the rotating mechanism 10 further includes a second connecting plate 18, which is fixed to the lifting frame 21. The first cylinder 1311 is fixed to the first connecting plate 17, and the buffer 40 is fixed to the lifting frame 21 via the second connecting plate 18. The buffer 40 is positioned toward the limiting protrusion 142. After the limiting protrusion 142 rotates a predetermined angle along with the connecting shaft 11, the buffer 40 abuts against the limiting protrusion 142, thereby achieving buffering.

[0066] In some embodiments, referring to Figures 3 and 5, the buffer 40 includes a hydraulic buffer 41, a first positioning member 42 and an anti-collision head 43. The first positioning member 42 is arranged on the hydraulic buffer 41, and the anti-collision head 43 is slidably arranged on the side of the first positioning member 42 away from the hydraulic buffer 41. The hydraulic buffer 41 can convert the mechanical energy of the anti-collision head 43 into internal energy.

[0067] In this embodiment, the anti-collision head 43 is located on the rotation track of the limiting protrusion 142 , and the limiting protrusion 142 rotates to contact the anti-collision head 43 to provide buffering.

[0068] In some embodiments, the anti-collision head 43 slides in the first positioning member 42 and then abuts against the first positioning member 42 , which can limit the rotation angle of the tray 30 and improve the rotation accuracy.

[0069] It is understandable that the movement stroke of the first piston rod 1312 in the first cylinder 131 can limit the rotation angle of the tray 30, and the abutment of the anti-collision head 43 against the first positioning member 42 can limit the rotation angle of the tray 30, thereby enhancing the accuracy of the rotation angle.

[0070] Exemplarily, the buffer 40 further includes bolts, and the hydraulic buffer 41 is fixed to the second connecting plate 18 by the bolts, thereby improving the stability of the buffer 40. For example, the buffer 40 includes two bolts, one on each side of the second connecting plate 18, and the hydraulic buffer 41 is inserted through the two bolts, and the bolts fix the hydraulic buffer 41 to the second connecting plate 18.

[0071] In some embodiments, referring to FIG. 2 , the lifting drive member 22 includes a second cylinder 221 , and the second cylinder 221 drives the lifting frame 21 to move in the up and down directions.

[0072] In this embodiment, the lifting frame 21 is driven by the second cylinder 221 to lift the tray 30. Before rotating the tray 30, the tray 30 is first lifted.

[0073] For example, please refer to Figure 2, the fixed mounting frame 60 includes a fixed frame 63, the second cylinder 221 includes a second cylinder barrel 2211 and a second piston rod 2212, the second cylinder barrel 2211 is fixedly connected to the bottom of the lifting frame 21, the second piston rod 2212 is passed through the lifting frame 21, and the second piston rod 2212 is fixedly connected to the fixed frame 63, and the second cylinder barrel 2211 can move in the up and down directions relative to the second piston rod 2211.

[0074] In this embodiment, the second cylinder 2211 drives the lifting frame 21 to move in the up and down directions, so that the lifting frame 21 and the rotating mechanism 10 can be lifted and lowered.

[0075] In some embodiments, as shown in FIG6 , a tray 30 includes a support platform 31 and a plurality of retaining members 32 . The support platform 31 is connected to the rotating shaft 12 . At least two retaining members 32 are located at opposite ends of the support platform 31 along a first direction, and can move away from or toward each other along the first direction, where the first direction is perpendicular to the vertical direction. For example, a photovoltaic module is placed on the support platform 31, and the two retaining members 32 clamp the photovoltaic module along the first direction.

[0076] In this embodiment, the support platform 31 is connected to the rotating shaft 12. When the rotary drive 13 drives the connecting shaft 11 to rotate and the clutch 14 engages the connecting shaft 11 and the rotating shaft 12, the connecting shaft 11 drives the rotating shaft 12 and the support platform 31 to rotate together. The two limiting members 32 can move away from or toward each other in the first direction, thereby adjusting the spacing between the two limiting members 32 to accommodate photovoltaic modules of different sizes.

[0077] It is understandable that when the size of the photovoltaic module is smaller than or equal to the coverage size of the support platform 31 , the limiting member 32 abuts against the support platform 31 .

[0078] For example, referring to Figure 6 , the tray 30 further includes a slide rail 34 and a slider 33. The slide rail 34 extends in a first direction, the slider 33 is fixed to the support platform 31, and the stopper 32 is connected to the end of the slide rail 34 away from the support platform 31. The slide rail 34 and the slider 33 slide together, thereby driving the stopper 32 to slide in the first direction to accommodate different photovoltaic module sizes.

[0079] Exemplarily, the tray 30 further includes a sliding drive member fixed to the support platform 31 , thereby providing power for the slide rail 34 to slide.

[0080] For example, the sliding drive member may be an electric cylinder, a pneumatic cylinder, an oil cylinder, a linear motor, or the like.

[0081] In some embodiments, referring to FIG7 , at least two stoppers 32 are located at opposite ends of the support platform 31 along the second direction, and can move away from or toward each other along the second direction. The first and second directions are both perpendicular to the up-down direction. In a plane perpendicular to the up-down direction, the first and second directions can be perpendicular to each other.

[0082] In this embodiment, the positioning members 32 are arranged in both the first and second directions to improve support stability. The first and second directions are both perpendicular to the vertical direction. When the lifting mechanism 20 lifts the rotating mechanism 10 and moves in the vertical direction, the tray 30 can stably support the photovoltaic module.

[0083] In some embodiments, referring to Figures 7-10, the rotary lifting device 100 includes a positioning mechanism 50, the positioning mechanism 50 includes a second positioning member 51 and a positioning drive member 52, the tray 30 is formed with a positioning groove 30a, and the positioning drive member 52 drives the second positioning member 51 to selectively enter or escape from the positioning groove 30a.

[0084] In this embodiment, the positioning mechanism 50 can improve the rotation accuracy of the rotating shaft 12 and the tray 30, and can improve the stability of the tray 30 after following the rotation of the rotating shaft 12, and reduce the error caused by the swing of the tray 30 due to the inertia of movement after following the rotation of the rotating shaft 12.

[0085] It is understood that the positioning mechanism 50 and the rotary drive member 13 cooperate to rotate the rotary shaft 12 to a predetermined angle, and the second positioning member 51 is inserted into the positioning slot 30a, thereby locking the tray 30. For example, when the rotary shaft 12 rotates 90°, the second positioning member 51 is inserted into the positioning slot 30a, locking the tray 30.

[0086] For example, referring to FIG. 4 , the rotary drive member 13 further includes a position sensor 132, which is fixed to the first cylinder 131. The first cylinder 131 includes a first cylinder barrel 1311 and a first piston rod 1312. The position sensor 132 is configured to detect the position information of the first piston rod 1312 in the extended position of the first cylinder barrel 1311 and promptly transmit the position information to the controller. The controller controls the positioning drive member 52 based on the position information detected by the position sensor 132. For example, when the position sensor 132 detects that the rotary shaft 12 has completed one rotation, the controller obtains the position information and controls the second positioning member 51 to insert into the positioning slot 30a, thereby locking the tray 30.

[0087] Exemplarily, the outer contour of the second positioning member 51 is adapted to the positioning groove 30 a , and the second positioning member 51 can enter the positioning groove 30 a .

[0088] In some embodiments, the second positioning member 51 is located on one side of the positioning slot 30a in the horizontal direction, and the positioning slot 30a has an opening toward the second positioning member 51. The positioning drive member 52 drives the second positioning member 51 to move in the horizontal direction and selectively enter or exit the positioning slot 30a.

[0089] In this embodiment, the positioning groove 30 a opens toward the second positioning member 51 , and the second positioning member 51 can enter the positioning groove 30 a in a horizontal direction, which can increase the speed at which the second positioning member 51 enters the positioning groove 30 a.

[0090] In some embodiments, the second positioning member 51 can rotate about an axis extending in the vertical direction. This can reduce frictional resistance when the second positioning member 51 is inserted into the positioning slot 30a, reduce equipment wear, increase the speed of the second positioning member 51 inserting into the positioning slot 30a, and improve production efficiency.

[0091] Exemplarily, the outer contour of the second positioning member 51 is circular, which reduces the friction resistance when the second positioning member 51 is inserted into the positioning groove 30 a.

[0092] In some embodiments, the number of the positioning mechanisms 50 and the number of the positioning slots 30 a are both four. The four positioning slots 30 a are symmetrically arranged in pairs along the diagonal line, and each positioning mechanism 50 corresponds to one positioning slot 30 a.

[0093] In this way, the rotary driving member 13 drives the rotary shaft 12 to rotate 90°, and the second positioning member 51 can be inserted into the positioning groove 30a for positioning.

[0094] Exemplarily, one group of symmetrically arranged positioning grooves 30 a is along the first direction, and another group of symmetrically arranged positioning grooves 30 a is along the second direction.

[0095] In some embodiments, referring to FIG. 2 , the lifting frame 21 includes a connecting post 211 extending in the vertical direction. The fixed mounting frame 60 is formed with a guide sleeve 62, and the connecting post 211 is slidably disposed within the guide sleeve 62. Thus, the connecting post 211 enables the lifting frame 21 to slide up and down along a set trajectory under the guidance of the guide sleeve 62, thereby reducing the possibility of the lifting frame 21 deviating from the set trajectory.

[0096] For example, referring to Figures 2-3, the lifting frame 21 includes two support plates 212 and a connecting column 211. The two support plates 212 are arranged in the up and down directions to form a receiving space. The connecting column 211 connects the two support plates 212, and at least part of the rotating mechanism 10 is located in the receiving space.

[0097] For ease of description, the upper support plate 212 is referred to as the first support plate 2121, and the lower support plate 212 is referred to as the second support plate 2122. The rotating mechanism 10 is fixed to the first support plate 2121, and the lifting mechanism 20 is fixed to the second support plate 2122. The lifting drive 22 drives the second support plate 2122 to move in the up and down directions, thereby achieving the lifting and lowering of the rotating mechanism 10 and the tray 30.

[0098] For example, referring to FIG3 , the rotating mechanism 10 further includes a first connecting plate 17 and a second connecting plate 18 , both of which are fixed to the first support plate 2121 . The first cylinder 131 is fixed to the first support plate 2121 via the first connecting plate 17 , and the buffer 40 is connected to the first support plate 2121 via the second connecting plate 18 . At least a portion of the first cylinder 131 and at least a portion of the buffer 40 are located in the accommodation space.

[0099] 2 , the fixed mounting frame 60 further includes a fixing plate 61, which is located between the guide sleeve 62 and the first support plate 2121, and the guide sleeve 62 is fixed below the fixing plate 61. In this way, the connecting column 211 can move in the up and down direction relative to the fixing plate 61.

[0100] The present disclosure also provides a conveying device 200, as shown in Figures 9-13. The conveying device 200 includes a support 110 and a rotary lifting device 100 according to any of the embodiments of the present disclosure. The support 110 is formed with a conveyor channel 1101 for conveying photovoltaic modules. The rotary lifting device 100 is mounted on the support 110, and a tray 30 is configured to carry photovoltaic modules. The tray 30 is capable of carrying photovoltaic modules from the conveyor channel 1101. After the photovoltaic modules are positioned in a different direction, they can continue to be transported along the conveyor channel 1101.

[0101] It is understandable that the bracket 110 is provided with a snap-in groove, and the fixing frame 63 can be snap-fitted into the snap-in groove of the bracket 110 to fix the fixing mounting frame 60 to the conveying channel 1101 .

[0102] Exemplarily, the transport channel 1101 is a conveyor belt, which is configured to transport photovoltaic components.

[0103] Exemplarily, the conveying device 200 further includes a sensor, which is fixed on the bracket 110 and is configured to detect whether the photovoltaic assembly is conveyed into place.

[0104] Taking one embodiment as an example, part of the operation process of the conveying equipment of the embodiment of the present disclosure is described:

[0105] The conveyor channel transports the photovoltaic modules to the top of the pallet;

[0106] The second piston rod retracts to drive the second cylinder to drive the lifting frame to lift the tray upward, wherein the clutch is in an engaged state of engaging the connecting shaft and the rotating shaft;

[0107] The first piston rod extends to drive the connecting shaft to rotate, causing the rotating shaft, tray and photovoltaic module to rotate 90 degrees in the forward direction;

[0108] The clutch disconnects the connecting shaft from the rotating shaft, and the first piston rod retracts;

[0109] The second piston rod extends to lower the lifting frame and the pallet;

[0110] The positioning driving member drives the second positioning member into the positioning groove;

[0111] The conveyor channel transports the photovoltaic modules away from the top of the pallet.

[0112] In this way, the position and direction of the current batch of photovoltaic modules are changed.

[0113] After the above process is completed, the clutch re-engages the connecting shaft and the rotating shaft to prepare for the position and direction change of the next batch of photovoltaic modules.

[0114] Please refer to FIG. 14 . An embodiment of the present disclosure further provides a photovoltaic module production line configured to produce photovoltaic modules. The photovoltaic module production line includes the conveying equipment according to an embodiment of the present disclosure.

[0115] The photovoltaic module production line provided by the embodiment of the present disclosure can change the placement direction of photovoltaic modules and improve production efficiency.

[0116] The various embodiments / implementations provided in the present disclosure can be combined with each other without causing any contradiction.

[0117] The above are only some embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
