Description

Technical Field

[0001] This invention relates to the field of photovoltaic module installation equipment technology, and in particular to a photovoltaic module transfer device. Background Technology

[0002] Microcracks in photovoltaic modules are a defect that occurs when cracks, invisible to the naked eye, appear inside the module. This is a strictly controlled defect in solar cells. Many factors can cause microcracks, one of which is human error. These can occur during various stages of production, transportation, installation, and maintenance. Although automated equipment is widely used in production, manual handling or equipment relocation during processes such as lamination, framing, and cleaning can still cause microcracks. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a photovoltaic module transfer device with high transfer efficiency and no microcracks in the battery module during the transfer process.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A photovoltaic module transfer device includes a support frame, which is a cross-shaped support frame. One horizontal bar has positioning rods connected to both ends, and the other horizontal bar has clamping mechanisms connected to both ends via connecting arms. The top end of the connecting arm passes through the horizontal bar, and the bottom end of the connecting arm is connected to the clamping mechanism. The clamping mechanism includes an upper pressure plate and a lower pressure plate, with one end of the upper and lower pressure plates connected by a connecting rod. The connecting rod has a cavity containing a compression spring. One end of the upper pressure plate is located within the cavity and connected to the compression spring. The upper and lower pressure plates are also connected by a threaded rod and a nut. An upper flexible pad is connected to the lower surface of the upper pressure plate, and a lower flexible pad is connected to the upper surface of the lower pressure plate. The upper and lower flexible pads are positioned correspondingly.

[0006] Furthermore, a guide plate is connected above the crossbar connected to the connecting arm. The guide plate and the crossbar are connected by a connecting post. The guide plate is provided with a limit hole. The connecting arm passes through the limit hole and is tightened by a nut.

[0007] Furthermore, the connecting arm is also connected to the lower surface of the crossbar by a nut.

[0008] Furthermore, the connecting arm and the clamping mechanism are connected by a reciprocating track, and the reciprocating track and the connecting arm are connected by welding. The clamping mechanism is connected to a lead screw stepper motor, and the clamping mechanism moves horizontally along the reciprocating track under the drive of the lead screw stepper motor.

[0009] Furthermore, the reciprocating track includes an upper track and a lower track arranged in opposite directions, with one end of the upper track and the lower track connected by a connecting plate. The connecting plate has a lead screw hole, and a stepper lead screw motor is located on the outside of the connecting plate. The clamping mechanism is located between the upper track and the lower track and is matched in size.

[0010] Furthermore, the upper flexible pad and the lower flexible pad are made of rubber material and each includes a cylindrical section and a cup-shaped section located at the top of the cylindrical section.

[0011] Furthermore, the positioning rod is a hydraulic lifting rod, and a support base is connected to the bottom of the positioning rod. The support base is a regular square pyramidal truncated pyramid, and a trapezoidal groove is on the lower surface of the support base. The outer surface of the support base is covered with a layer of flexible rubber pad.

[0012] Furthermore, after installation, the length of the positioning rod is greater than the length of the connecting arm.

[0013] Furthermore, a lifting ring is connected to the top of the bracket, and a retaining ring is provided inside the lifting ring.

[0014] Furthermore, the two crossbars in the cross bracket are connected by welding, and a reinforcing bar is connected between adjacent sections of the two crossbars.

[0015] The beneficial effects of adopting the technical solution of the present invention are:

[0016] The photovoltaic module transfer device of this invention has a simple structure and reasonable design. The top of the connecting arm passes through a crossbar, and the bottom of the connecting arm is connected to a clamping mechanism. This allows the connecting arm to move up and down, thereby adapting to photovoltaic modules with different stacking heights and improving efficiency. The clamping mechanism includes an upper pressure plate and a lower pressure plate, one end of which is connected by a connecting rod. The connecting rod has a cavity with a compression spring inside. One end of the upper pressure plate is located in the cavity and connected to the compression spring, allowing the upper pressure plate to move up and down along the cavity. This enables quick adjustment of the clamping and releasing mechanism, making operation more convenient.

[0017] The compression spring structure in this invention provides a buffer force between the upper and lower pressure plates, which further ensures that the force applied to the photovoltaic module during installation and clamping is not too large, thus further avoiding the risk of microcracks in the photovoltaic module.

[0018] In this invention, the lower surface of the upper pressure plate is connected to an upper flexible pad, and the upper surface of the lower pressure plate is connected to a lower flexible pad. The upper and lower flexible pads are positioned correspondingly. By adopting the above structural design, the risk of microcracks occurring in the photovoltaic module during the transfer process is further reduced. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. The following embodiments will enable those skilled in the art to gain a more comprehensive understanding of the present invention, but these embodiments are not intended to limit the scope of protection of the present invention. As used herein, "an embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Please see Figure 1 , Figure 2 and Figure 3The photovoltaic module transfer device of this invention includes a support 1, which is a cross-shaped support. One horizontal bar has positioning rods 3 connected to both ends, and the other horizontal bar has clamping mechanisms connected to both ends via connecting arms 2. The top end of the connecting arm 2 passes through the horizontal bar, and the bottom end of the connecting arm 2 is connected to the clamping mechanism. This allows the connecting arm 2 to move up and down, adapting to photovoltaic modules of different stacking heights and improving efficiency. The clamping mechanism includes an upper pressure plate 6 and a lower pressure plate 7, one end of which is connected by a connecting rod. The connecting rod has a cavity containing a compression spring 14. One end of the upper pressure plate 6 is located within the cavity and connected to the compression spring 14. This design allows the upper pressure plate 6 to move up and down along the cavity, enabling quick adjustment of the clamping and releasing mechanism, making operation more convenient. The structure of the compression spring 14 provides a buffer between the upper pressure plate 6 and the lower pressure plate 7, ensuring that the force applied to the photovoltaic module during installation and clamping is not too large, thus further avoiding the risk of microcracks in the photovoltaic module. The upper pressure plate 6 and the lower pressure plate 7 are also connected by a threaded rod 11 and a nut. After the distance between the upper pressure plate 6 and the lower pressure plate 7 is adjusted, the upper pressure plate 6 is further fixed by the threaded rod 11 and the nut, ensuring safety during the transfer process and high operational efficiency. The lower surface of the upper pressure plate 6 is connected to an upper flexible pad 8, and the upper surface of the lower pressure plate 7 is connected to a lower flexible pad 9. The upper flexible pad 8 and the lower flexible pad 9 are positioned correspondingly. The above structural design further reduces the risk of microcracks in the photovoltaic module during the transfer process.

[0025] During operation, the transfer device is moved to the photovoltaic module. The positioning rod 3 serves to position and support the module. The distance between the two positioning rods 3 is greater than the length or width of the photovoltaic module. The clamping mechanism at the lower end of the connecting arm 2 clamps the photovoltaic module. The lifting mechanism hooks the bracket 1 and transfers it to the destination. In this embodiment, by setting an upper flexible pad 8 and a lower flexible pad 9 on the upper pressure plate 6 and the lower pressure plate 7 respectively, it is possible to avoid the pressure plate squeezing the photovoltaic module during the clamping process, which would cause microcracks in the photovoltaic module and affect the quality of the photovoltaic module.

[0026] A guide plate 4 is connected above the crossbar connected to the connecting arm 2. The guide plate 4 is connected to the crossbar through a connecting column. The guide plate 4 is provided with a limit hole. The connecting arm 2 passes through the limit hole and is tightened by a nut. With this structural design, the connecting arm 2 will not be displaced when it moves up and down, ensuring that the connecting arm 2 remains vertical during the up and down movement, thereby improving the up and down movement efficiency of the connecting arm 2.

[0027] The connecting arm 2 is also connected to the lower surface of the crossbar by a nut. This structural design can further improve the installation stability of the connecting arm 2.

[0028] To facilitate adjustment of the distance between the clamping mechanism and the photovoltaic module, in this embodiment, the connecting arm 2 and the clamping mechanism are connected via a reciprocating track 5. The reciprocating track 5 and the connecting arm 2 are welded together. The clamping mechanism is connected to a lead screw stepper motor 12. Driven by the lead screw stepper motor 12, the clamping mechanism moves horizontally along the reciprocating track 5. By using the lead screw stepper motor 12 to drive the clamping mechanism to move back and forth along the reciprocating track 5, the distance between the clamping mechanism and the photovoltaic module can be adjusted, resulting in higher operating efficiency. The reciprocating track 5 includes an upper track and a lower track arranged in opposite directions. One end of the upper track and the lower track are connected by a connecting plate. A lead screw hole is opened on the connecting plate. The stepper lead screw motor is located on the outside of the connecting plate. The clamping mechanism is located between the upper track and the lower track and their sizes are matched. This structural design is reasonable. In this embodiment, the length of the lead screw is less than the length of the reciprocating track 5, which ensures that the clamping mechanism will not detach from the track during movement.

[0029] In this embodiment, the upper flexible pad 8 and the lower flexible pad 9 are made of rubber material and include a cylindrical section and a cup-shaped section at the top of the cylindrical section, respectively. With this structural design, when the cup-shaped section contacts the photovoltaic module, a certain vacuum area will be formed at the contact surface between the flexible pad and the photovoltaic module, which improves the tightness of the connection between the flexible pad and the photovoltaic module and further improves the clamping operation efficiency.

[0030] In this embodiment, the positioning rod 3 is a hydraulic lifting rod. A support base 10 is connected to the bottom of the positioning rod 3. The support base 10 is a frustum-shaped square pyramid with a trapezoidal groove on its lower surface. The outer surface of the support base 10 is covered with a flexible rubber pad. This structural design allows the height of the positioning rod 3 to be adjusted to match the stacking height according to actual usage needs. After installation, the length of the positioning rod 3 is greater than the length of the connecting arm 2.

[0031] In this embodiment, a lifting ring 13 is connected above the support 1. A retaining ring is provided inside the lifting ring 13. A clamping area is formed between the retaining ring and the lifting ring 13, which can ensure that the lifting hook of the crane does not come out and improve the safety of use.

[0032] The two crossbars in the cross bracket 1 are connected by welding, and a reinforcing bar 15 is connected between adjacent sections of the two crossbars. This structural design further improves the connection strength of the bracket 1.

[0033] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of the invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
