Description

Technical Field

[0001] The utility model relates to the manufacturing field of photovoltaic products, in particular to a stacking device for photovoltaic products. Background Art

[0002] In the production and storage of photovoltaic products, automated mechanical stacking technology should theoretically be an ideal choice due to its high efficiency, space-saving, and labor-cost-reducing advantages. However, in practice, photovoltaic products face numerous challenges related to automated mechanical stacking, which significantly restricts improvements in production efficiency and warehouse management.

[0003] First, photovoltaic products are large, heavy, and irregularly shaped, making them difficult to accurately grasp and position using traditional automated mechanical stacking equipment. Furthermore, the surface of photovoltaic products is easily damaged, requiring extreme precision and stability during the stacking process to avoid damage.

[0004] Secondly, photovoltaic products are produced in diverse batches and specifications, and products of different sizes and weights require different stacking strategies. This requires stacking equipment to be highly flexible and adaptable, but the mechanical and automated stacking equipment currently on the market often fails to meet this requirement.

[0005] Furthermore, the storage environment for photovoltaic products is complex, subject to fluctuations in temperature, humidity, and other environmental factors, which can disrupt the stable operation of stacking equipment. In particular, high temperatures and humidity increase equipment failure rates, further impacting the automation level of stacking.

[0006] In summary, the inability to perform automated mechanical stacking of photovoltaic products during actual production has become a bottleneck restricting the industry's development. Therefore, a mechanical automated stacking system and method tailored to the characteristics of photovoltaic products is urgently needed to address the existing technical issues, improve production efficiency and warehouse management, and promote the sustainable and healthy development of the photovoltaic industry.

[0065] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0066] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0067] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0068] In order to solve the problem that photovoltaic products in the prior art cannot be stacked automatically, the utility model provides a stacking device that can be used for stacking photovoltaic products.

[0069] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0070] like Figure 1-4 As shown, the present invention provides a stacking device for photovoltaic products, which includes a container box 1, a three-dimensional shelf 2 and a transfer module. The container box 1 is used to load the photovoltaic products.

[0071] The three-dimensional shelf 2 is in length, width, height (reference Figure 1 ) is extended in three directions and has multiple spaced-apart carrying units 21, the carrying units 21 include shelves 211, the container box 1 can be moved onto the shelves 211, and the three-dimensional shelf includes multiple carrying units 21, so that multiple quantities of photovoltaic products can be stacked, thereby saving production space.

[0072] The transfer module 3 is spaced apart from the loading unit 21 along the width direction and comprises a support mechanism 31 and a transport unit 32. The transport unit 32 comprises a mounting base 321 and a clamping mechanism 322. The support mechanism 31 is mounted on the three-dimensional shelf 2 and can move back and forth along the length direction. The mounting base 321 is mounted on the support mechanism 31 and can move back and forth along the height direction. The clamping mechanism 322 is mounted on the mounting base 321 and can move toward or away from the shelf 211 along the width direction. Thus, the container box 1 is placed on the shelf 211 or clamped and removed from the shelf 211.

[0073] Through the above arrangement, the container box 1 can accommodate photovoltaic products of various specifications, the support mechanism 31 can move back and forth along the length direction, the mounting base 321 can move back and forth along the height direction on the support mechanism 31, and the clamping mechanism 322 is arranged on the mounting base 321 and can move toward or away from the shelf 211 along the width direction. Through such an arrangement, photovoltaic products can be stacked in the length, width and height directions.

[0074] It should be noted that, in this embodiment, reference Figure 1 As shown, in Figure 1 The end facing the paper is defined as the near end, and the end facing away from the paper is defined as the far end.

[0075] Furthermore, the transport unit 32 is further equipped with a first sensor 323, which is cleverly mounted on the distal side of the mounting base 321. The main function of the first sensor 323 is to accurately detect whether there is a container box 1 on the shelf 211. When the sensor detects that there is a container box on the shelf, it sends a signal to the control system, instructing the clamping mechanism 322 to perform a moving operation; on the contrary, if the sensor finds that there is nothing on the shelf, it triggers the clamping mechanism to accurately place the new container box 1 on the shelf 211. This design not only improves the degree of automation of the stacking process, but also ensures the accuracy and efficiency of the operation, thereby further optimizing the stacking process of photovoltaic products.

[0076] Furthermore, the stacking device design further incorporates the concept of efficient logistics, specifically by adding a conveyor belt 4 that extends along the length and cleverly passes through the interior of the three-dimensional shelf 2. This conveyor belt 4 not only bears the heavy responsibility of carrying the containers 1, but also extends outside the three-dimensional shelf at both ends, forming a convenient feed end 41 and discharge end 42, greatly enhancing the flexibility of material handling.

[0077] Even more ingenious is the reserved space within the three-dimensional shelf 2 to accommodate the transport unit 32. When the transport unit 32 needs to perform stacking or retrieving tasks, it flexibly moves into this space. At this point, the first sensor 323 plays a crucial role, accurately sensing whether a container box 1 is placed above the conveyor belt 4 at the position corresponding to the first sensor 323.

[0078] This design achieves seamless collaboration between the transport unit 32 and the conveyor belt 4. When the first sensor 323 detects that there is a container box 1 on the shelf 211 that needs to be moved out, it will quickly send a signal to the control system, instructing the clamping mechanism 322 to perform the removal operation and place the container box 1 securely on the conveyor belt 4 for subsequent processing. On the contrary, if the shelf 211 is empty, the transport unit 32 will quickly move to the avoidance space and use the first sensor 323 to confirm again whether there is a container box 1 to be stacked on the conveyor belt 4. If there is a container box 1 on the conveyor belt 4, the clamping mechanism 322 will take action immediately and place it accurately on the corresponding shelf 211; if there is no container box 1 on the conveyor belt 4, the control system will start the conveyor belt 4 and transport the next container box 1 to the designated position, and then the clamping mechanism 322 will complete the stacking task.

[0079] Such a design not only greatly improves the degree of automation of the stacking device, but also realizes the efficiency, accuracy and flexibility of the photovoltaic product stacking process through the close cooperation between the conveyor belt 4 and the handling unit 32.

[0080] Further, refer to Figure 3 and Figure 4 As shown, the design of the clamping mechanism 322 is exquisite and practical, and its core components include a first clamping plate 3221 and a second clamping plate 3222 arranged opposite to each other in the width direction. The second clamping plate 3222 is fixed at a proximal position close to the transport unit 32, serving as a stable fulcrum for the clamping operation. The first clamping plate 3221 has the ability to move flexibly in the width direction and can move toward or away from the second clamping plate 3222 according to control instructions. When it is necessary to clamp the container box 1, the first clamping plate 3221 will move closer to the second clamping plate 3222, and the two will work together to firmly fix the container box 1; and when it is necessary to release the container box 1, the first clamping plate 3221 will move away from the second clamping plate 3222, providing sufficient space for taking out or placing the container box 1. Such a design not only ensures the stability of the clamping, but also greatly improves the flexibility and efficiency of the operation, and can adapt to container boxes 1 of different sizes.

[0081] Furthermore, the structure of the clamping mechanism 322 is further refined to ensure its precise and reliable clamping action. The mechanism is also equipped with a mounting member 3223 and a telescopic motor 3224 as a power source. The telescopic motor 3224 consists of a motor body 32241 and an output shaft 32242 mounted thereon. This design achieves efficient power transmission. The motor body 32241 is securely mounted between the second clamping plate 3222 and the mounting member 3223, providing solid support for the entire clamping mechanism. The output shaft 32242 is cleverly inserted into the second clamping plate 3222 and tightly connected to the first clamping plate 3221. When the telescopic motor 3224 is activated, the output shaft 32242 drives the first clamping plate 3221 to reciprocate in the width direction, thereby achieving a coordinated clamping or release action with the second clamping plate 3222. This structure is not only simple and clear, but also ensures a stable and reliable clamping force through the precise control of the motor.

[0082] Further references Figure 4As shown, the structural design of the transport unit 32 fully considers the smoothness and precision of movement. Its core components include at least one guide rail 324 and a synchronous belt drive mechanism 325. The synchronous belt drive mechanism 325 consists of a synchronous belt 3251, a drive motor 3252, a first synchronous pulley 3253, and a second synchronous pulley 3254, forming a highly efficient transmission system. At least one guide rail 324 is precisely mounted on the upper surface of the mounting base 321 parallel to the width direction, providing stable guidance for the transport unit. The mounting member 3223 is cleverly slidably mounted on these guide rails 324 and tightly connected to the synchronous belt 3251 via a connector. When the drive motor 3252 is activated, it drives the mounting member 3223 via the synchronous belt 3251 to perform precise sliding movement along the guide rail 324. This design not only ensures stable movement of the transport unit 32 in the width direction, but also, through the high-precision characteristics of the synchronous belt drive, enables precise control of the position of the clamping mechanism 322, thereby meeting the stringent positioning accuracy requirements of automated stacking processes.

[0083] The transport unit 32 is also cleverly integrated with a second sensing member 326. This design greatly improves the automation and safety of the system. The second sensing member 326 is carefully installed on the upper surface of the mounting base 321 near its proximal end. Its main function is to accurately sense whether the mounting member 3223 has successfully reached the preset initial position. In this embodiment, the initial position is the extreme position that the mounting member 3223 can reach when sliding toward the proximal end on the guide rail 324. In this position, the positive projection of the clamping mechanism 322 on the upper surface of the mounting base 321 is located inside the edges of the upper surface, thereby ensuring that when the mounting member 3223 is in this initial position, the clamping mechanism 322 is stable and safe above the mounting base 321.

[0084] Furthermore, the design of the transport unit 32 also includes a third sensor 327, which is cleverly placed on the upper surface of the mounting base 321 to further enhance the system's intelligence and automation. The main function of the third sensor 327 is to accurately determine whether the clamping mechanism 322 has successfully clamped the container box 1 when the mounting member 3223 is firmly in its initial position. Normally, the clamping mechanism 322 remains in its stowed state, suspended above the upper surface of the mounting base 321, at which point the mounting member 3223 is precisely in its initial position. Through the precise sensing of the third sensor 327, the system can quickly identify the current state of the clamping mechanism 322—whether it is in an idle waiting state or has already clamped the container box 1 and is ready for the next step. This design not only enhances the system's real-time monitoring capabilities of the operating status, but also provides a more precise control basis for subsequent operation processes, thereby ensuring the smooth and efficient operation of the entire automated stacking process.

[0085] Furthermore, the structure of the three-dimensional shelf 2 cleverly incorporates a base plate 23, a top plate 22, and two key first linear motion modules 24. These components are positioned opposite each other in the height direction, together forming a stable and flexible support frame. The base plate 23 and the top plate 22 serve as the foundation and roof of the entire shelf, not only providing the necessary structural strength but also providing a broad platform for storing and transporting goods. The two first linear motion modules 24 are respectively mounted on the base plate 23 and the top plate 22, forming a tight transmission cooperation relationship with the support mechanism 31, ensuring that the support mechanism 31 can move freely and smoothly back and forth along the length of the shelf.

[0086] Specifically, the first linear motion module 24 integrates core components such as the first drive member 241, the linear guide rail 242, and the first rack 243. The first drive member 241 is connected to the support mechanism 31, and the gear assembled on its pivot shaft is tightly engaged with the first rack 243, forming a stable transmission chain. When the drive member is started, the gear slowly rolls along the rack, thereby driving the entire first drive member 241 to move precisely along the length of the shelf under the guidance of the linear guide rail 242. This process not only achieves efficient displacement of the support mechanism 31, but also ensures the stability and reliability of the entire handling process, providing solid technical support for the efficient operation of the three-dimensional shelf 2.

[0087] Furthermore, the support mechanism 31 is ingeniously designed and practical, primarily comprising a support column 311 and a second linear motion module 312 mounted thereon. The support column 311 serves as the framework of the entire mechanism, extending vertically and providing solid support for the transport unit 32. The second linear motion module 312 is connected to the mounting base 321 and engages with the support column 311 to drive the transport unit 32 back and forth in the vertical direction.

[0088] Generally speaking, the second linear motion module 312 includes a second driving member 3121 and a second rack 3122. The second rack 3122 extends parallel to the height direction and is arranged on the supporting column 311. The pivot end of the second driving member 3121 is provided with gear teeth that cooperate with the second rack 3122. The second driving member 3121 is connected to the mounting base 321 through a connecting member. When the gear teeth cooperate with the second rack 3122 on the supporting column 311 and move along the height direction, it can drive the mounting base 321 to move in the height direction.

[0089] In summary, the embodiments of the present invention achieve the following technical effects:

[0090] The container box 1 can accommodate photovoltaic products of various specifications. The support mechanism 31 can move back and forth along the length direction. The mounting base 321 can move back and forth along the height direction on the support mechanism 31. The clamping mechanism 322 is arranged on the mounting base 321 and can move toward or away from the shelf 211 along the width direction. Through such an arrangement, photovoltaic products can be stacked in the length, width and height directions.
