Description

Technical Field

[0001] This utility model relates to the field of photovoltaic frame production technology, and in particular to a photovoltaic frame stacking device. Background Technology

[0002] After a series of production processes and visual inspections, photovoltaic (PV) frames need to be stacked to prepare for subsequent shipment. While efficient methods using robotic arms or other automated devices to grasp and stack PV frames have emerged, these devices often handle multiple frames at a time, making them unusable when workspace is limited.

[0003] Therefore, when the workspace is limited, it is still necessary to work manually by stacking two photovoltaic frames at a time. The whole process is not only time-consuming and labor-intensive, but it is also easy to fall behind the pace of the overall production line, affecting the overall production efficiency of photovoltaic frames. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a photovoltaic frame stacking device that occupies little space and ensures high production efficiency.

[0005] The present invention adopts the following technical solution:

[0006] This utility model provides a photovoltaic frame stacking device, including a linear track, stacking modules, and a controller. The linear track is divided into two sets of sliding guide rails in the middle. Each set of sliding guide rails has a stacking module slidably mounted on it. The stacking module is equipped with a lifting component and a rotating component. The lifting component is connected to the rotating component and can drive the rotating component to lift and lower. The rotating component is equipped with a clamping component that can clamp one end of the photovoltaic frame along its length. The rotating component can drive the clamping component to rotate. The clamping components on the two stacking modules are arranged facing each other, and the lifting component, rotating component, and clamping component on the two stacking modules are all signal connected to the controller.

[0007] Preferably, the stacking module includes a sliding base and a locking component. The lifting component is disposed on the sliding base, which is linearly slidable on the sliding guide rail. The locking component is disposed on the sliding base and can lock the sliding base onto the sliding guide rail.

[0008] Preferably, the lifting assembly includes a lifting cylinder and a lifting seat. The lifting cylinder is fixed on the sliding base and connected to the controller signal. The lifting end of the lifting cylinder extends out of the sliding base and is connected and fixed to the lifting seat. The rotating assembly is mounted on the lifting seat.

[0009] Preferably, a distance sensor is provided on the lifting end of the lifting cylinder. The distance sensor is used to measure the distance between the lifting end of the lifting cylinder and the area below. The distance sensor is connected to the controller signal.

[0010] Preferably, the sliding base is provided with multiple linear bearings at intervals, and the lifting base is fixed with multiple guide supports at intervals. Each guide support is fixed with a guide shaft, and the multiple guide shafts are correspondingly inserted into the multiple linear bearings.

[0011] Preferably, a buffer block is fixed on the sliding base, and the buffer block is located between the sliding base and the lifting base.

[0012] Preferably, a hydraulic damper is provided between the sliding base and the lifting base.

[0013] Preferably, the rotating assembly includes a rotary motor, a rotary shaft, and a seated bearing. Both the rotary motor and the seated bearing are fixed on the lifting seat, and the rotary motor is signal-connected to the controller. The rotary shaft passes through the seated bearing, the drive end of the rotary motor extends laterally and is axially connected to one end of the rotary shaft, and the other end of the rotary shaft is axially connected to the clamping assembly.

[0014] Preferably, the clamping component is a clamping cylinder, and the clamping ends of the clamping components on the two stacking modules are arranged facing each other.

[0015] Preferably, the lifting seat is provided with an exhaust valve group, which is connected to the clamping cylinder, and the controller is signal-connected to the exhaust valve group.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The photovoltaic frame stacking device of this invention uses only the clamping components on two stacking modules to perform the flipping and stacking operation on a single photovoltaic frame. Compared with traditional robotic arms or other automated devices that can grab multiple photovoltaic frames at once for flipping and stacking, the photovoltaic frame stacking device of this invention occupies less space and can therefore be applied in situations where workspace is limited.

[0018] Furthermore, in actual use, the linear track of the photovoltaic frame stacking device of this invention is installed on the photovoltaic frame production line. When the photovoltaic frame stacking operation officially begins, the spacing between the two stacking modules can be adjusted according to the size of the photovoltaic frame. Then, the clamping components on the two stacking modules clamp the photovoltaic frame to prevent it from falling during operation. Afterwards, the rotating component drives the photovoltaic frame to deflect 180°, and the lifting component lifts the photovoltaic frame. The photovoltaic frame production line then continues to transport new photovoltaic frames to the original position. The controller then controls the lifting component to lower the photovoltaic frame, completing the stacking of two photovoltaic frames. Finally, the photovoltaic frame stacking device is reset to await the next photovoltaic frame stacking operation. Clearly, compared to traditional manual operation, the photovoltaic frame stacking device of this invention not only ensures production efficiency but also improves the accuracy of the stacking operation.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] See Figure 1 and Figure 2 This embodiment provides a photovoltaic frame stacking device, including a linear track, stacking modules 1, and a controller. The linear track is divided into two sets of sliding guide rails 2 in the middle. Each set of sliding guide rails 2 has a stacking module 1 slidably mounted on it. The stacking module 1 is equipped with a lifting component 3 and a rotating component 4. The lifting component 3 is connected to the rotating component 4 and can drive the rotating component 4 to rise and fall. The rotating component 4 is equipped with a clamping component 6 that can clamp one end of the photovoltaic frame 5 in the length direction. The rotating component 4 can drive the clamping component 6 to rotate. The clamping components 6 on the two stacking modules 1 are arranged facing each other, and the lifting component 3, rotating component 4, and clamping component 6 on the two stacking modules 1 are all signal connected to the controller.

[0038] The photovoltaic frame stacking device of this embodiment only uses the clamping components 6 on the two stacking modules 1 to perform the flipping and stacking operation on one photovoltaic frame 5. Compared with traditional robotic arms or other automated devices that can grab multiple photovoltaic frames 5 at a time for flipping and stacking, the photovoltaic frame stacking device of this embodiment occupies less space and can therefore be applied to occasions with limited workspace.

[0039] Furthermore, in this embodiment, the photovoltaic frame stacking device uses a linear track installed on the photovoltaic frame production line. When the stacking operation of the photovoltaic frame 5 begins, the distance between the two stacking modules 1 can be adjusted according to the size of the photovoltaic frame 5. The clamping components 6 on the two stacking modules 1 then clamp the photovoltaic frame 5 to prevent it from falling during operation. Afterwards, the rotating component 4 drives the photovoltaic frame 5 to rotate 180°, and the lifting component 3 lifts the photovoltaic frame 5. The photovoltaic frame production line then continues to transport new photovoltaic frames to the original position of the photovoltaic frame. The controller then controls the lifting component 3 to lower the photovoltaic frame 5, completing the stacking of the two photovoltaic frames. Finally, the photovoltaic frame stacking device is reset to its original position, ready for the next stacking operation. Clearly, compared to traditional manual operation, the photovoltaic frame stacking device in this embodiment not only ensures production efficiency but also improves the accuracy of the stacking operation.

[0040] It should be noted that the photovoltaic frame production line is equipped with sensors at the stacking position to detect whether the new photovoltaic frame has reached the position of the original photovoltaic frame. This is a mature technology in the photovoltaic frame production line field, and will not be elaborated on here.

[0041] Preferably, in this embodiment, the controller is preferably a PLC controller, and the controller can be the existing controller on the photovoltaic frame production line.

[0042] Preferably, see Figures 2 to 4 The stacking module 1 includes a sliding base 101 and a locking component. The lifting component 3 is mounted on the sliding base 101. The sliding base 101 is linearly slidable on the sliding guide rail 2. The locking component is mounted on the sliding base 101 and can lock the sliding base 101 onto the sliding guide rail 2.

[0043] When it is necessary to adjust the spacing between the two stacked modules 1, the sliding base 101 can be unlocked and slid on the sliding guide rail 2 to accommodate photovoltaic frames 5 of different sizes. After the adjustment is completed, the sliding base 101 can be locked on the sliding guide rail 2 by the locking component, so that the photovoltaic frame 5 can be clamped by the clamping component 6 in the future.

[0044] Preferably, in this embodiment, the locking element can be a fastening screw, which is screwed onto the sliding base 101 and locks the sliding base 101 by pressing against the sliding guide rail 2.

[0045] Preferably, see Figures 2 to 4 The lifting assembly 3 includes a lifting cylinder 301 and a lifting seat 302. The lifting cylinder 301 is fixed on the sliding base 101 and connected to the controller signal. The lifting end of the lifting cylinder 301 extends out of the sliding base 101 and is connected and fixed to the lifting seat 302. The rotating assembly 4 is mounted on the lifting seat 302. When it is necessary to control the lifting of the photovoltaic frame 5, the controller can control the lifting cylinder 301 to lift and lower the photovoltaic frame 5 clamped on the clamping assembly 6 synchronously.

[0046] Preferably, a distance sensor is provided on the lifting end of the lifting cylinder 301. The distance sensor is used to measure the distance between the lifting end of the lifting cylinder 301 and the lower part. The distance sensor is connected to the controller signal.

[0047] The presence of a distance sensor allows the controller to precisely control the lifting cylinder 301. When the photovoltaic frame 5 is lifted to the set height, the distance sensor sends a signal to the controller, at which point the controller controls the lifting cylinder 301 to stop lifting. When the photovoltaic frame 5 is lowered to the set height, the distance sensor sends a signal to the controller again, at which point the controller controls the lifting cylinder 301 to stop lowering.

[0048] Preferably, see Figure 3 and Figure 4 The sliding base 101 is provided with multiple linear bearings 102 spaced apart, and the lifting base 302 is fixed with multiple guide supports 303 spaced apart. Each guide support 303 is fixed with a guide shaft 304, and the multiple guide shafts 304 are correspondingly inserted into the multiple linear bearings 102. The insertion of the guide shafts 304 into the linear bearings 102 can provide guidance for the lifting cylinder 301, making the height adjustment process of the photovoltaic frame 5 more stable.

[0049] Preferably, see Figure 3 A buffer block 103 is fixed on the sliding base 101, and the buffer block 103 is located between the sliding base 101 and the lifting seat 302. The buffer block 103 can buffer the lifting seat 302, prevent excessive noise when the lifting cylinder 301 drives the lifting seat 302 to descend, and also avoid collision damage between the lifting seat 302 and the sliding base 101.

[0050] Preferably, a hydraulic buffer is provided between the sliding base 101 and the lifting base 302 to further improve the buffering effect on the lifting base 302.

[0051] Preferably, see Figure 4 The rotating assembly 4 includes a rotary motor 401, a rotating shaft 402, and a bearing 403. Both the rotary motor 401 and the bearing 403 are fixed to the lifting seat 302. The rotary motor 401 is signal-connected to the controller. The rotating shaft 402 passes through the bearing 403. The drive end of the rotary motor 401 extends laterally and is axially connected to one end of the rotating shaft 402. The other end of the rotating shaft 402 is axially connected to the clamping assembly 6. When the angle of the photovoltaic frame 5 needs to be adjusted, the controller controls the rotary motor 401 to rotate the clamping assembly 6 by a specified angle.

[0052] Preferably, the clamping component 6 is a clamping cylinder, and the clamping ends of the clamping components 6 on the two stacking modules 1 are arranged facing each other.

[0053] Preferably, see Figure 4 The lifting seat 302 is equipped with an exhaust valve group 7, which is connected to the clamping cylinder. The controller is also connected to the exhaust valve group 7. By controlling the opening of the exhaust valve group 7, the clamping speed of the clamping cylinder can be precisely adjusted.

[0054] In summary, the photovoltaic frame stacking device of this utility model lifts and rotates the photovoltaic frame using mechanical and electronic means, and can be adaptively adjusted according to different photovoltaic frame size specifications to realize stacking operations, thereby improving the overall production efficiency and accuracy of photovoltaic frames.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
