Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic glass guides and relates to a photovoltaic glass guide device. Background Art

[0002] Amid the rapid growth of the photovoltaic industry, photovoltaic glass, a key component of solar panels, faces significant challenges in terms of quality and production efficiency, directly impacting the performance and cost of the entire photovoltaic system. The importance of cleaning in the processing of photovoltaic glass is paramount, ensuring surface cleanliness and improving photovoltaic conversion efficiency. However, while achieving efficient cleaning, existing photovoltaic glass cleaning machines also face numerous design challenges with their guide wheel systems. Guide wheels are a crucial component of photovoltaic glass cleaning machines. As photovoltaic glass is transported within the cleaning machine, they are impacted by rollers, sprays, and other factors, causing partial or complete deviation. The guide wheels function by slightly impacting the glass against their edges, causing them to rotate and change direction. As the glass moves forward, it continuously pushes against several or individual guide wheels, ultimately correcting the overall direction of the glass and ensuring a straight, non-deflecting transport within the cleaning machine. Currently used guide wheels frequently contact the glass edges and withstand significant impact, resulting in increased wear, shortened service life, and significantly increased replacement frequency. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problem in the prior art that the existing guide wheels need to frequently contact the edge of the glass and withstand a certain impact force, resulting in increased wear and shortened service life, and to provide a photovoltaic glass guide device.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A photovoltaic glass guide device comprises a base connecting plate, a transition plate, a guide wheel base and a guide wheel;

[0006] The base connecting plate is an L-shaped structure and is provided with a strip hole on the base connecting plate; the transition plate is a two-sided vertical structure and is provided with a strip hole on the horizontal surface of the transition plate, which is connected to the base connecting plate; the vertical surface of the transition plate is provided with a stepped hole, which is connected to the guide wheel base; the guide wheel base is provided with a guide wheel.

[0007] Furthermore, the strip-shaped holes on the base connecting plate are connected to the strip-shaped holes on the transition plate.

[0008] Furthermore, a plurality of stepped holes are provided on the stepped hole.

[0009] Furthermore, the guide wheel and the guide wheel base are fixed via a stepped shaft.

[0010] Furthermore, a retaining spring is provided at the top end of the stepped shaft.

[0011] Furthermore, the height of the guide wheel is greater than that of the deep groove ball bearing 6002 .

[0012] Furthermore, the guide wheel base is an L-shaped structure, and the guide wheel is arranged in the horizontal direction of the guide wheel base.

[0013] Furthermore, the guide wheel is made of PEEK.

[0014] Furthermore, the width of the strip-shaped hole is 6 mm.

[0015] Furthermore, the inner diameter, outer diameter and thickness of the guide wheel are all the same as those of the deep groove ball bearing 6002.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The utility model discloses a photovoltaic glass guide device, which combines an L-shaped base connecting plate with two vertical transition plates, effectively enhancing the overall rigidity and stability of the device. The guide wheel is firmly mounted on the transition plate via the guide wheel base, ensuring that the photovoltaic glass can move along a precise straight path during the cleaning process, significantly reducing offset and improving guiding accuracy. The design of the guide wheel and its base takes into account wear resistance and durability. By selecting high-quality materials or performing special treatments, such as surface hardening, the service life of the guide wheel is effectively extended. In addition, the stepped hole design allows the positioning bolts to be quickly removed and the guide wheel position to be changed without stopping the machine, facilitating the stable installation of the guide wheel base, allowing the worn contact surface to be moved, and the unworn contact surface to continue to be used. This design increases the service life of the guide wheel, reduces the frequency of replacement, and improves the utilization rate of the equipment. Bar holes are provided on both the base connecting plate and the transition plate. This design makes the installation and adjustment of the guide device inside the cleaning machine more flexible and convenient. At the same time, the introduction of stepped holes simplifies the connection process between the guide wheel base and the transition plate, making the replacement and maintenance of the guide wheel faster and more efficient, reducing downtime and maintenance costs.

[0018] Furthermore, the strip holes in the base connecting plate connect to the strip holes in the transition plate, allowing the relative position of the base connecting plate and the transition plate to be adjusted within a certain range. This flexibility is crucial for adapting to different types and sizes of photovoltaic glass and different installation environments. By adjusting the position of the bolts in the strip holes, the guide device can be perfectly aligned with the other components of the cleaning machine, achieving precise installation.

[0019] Furthermore, the stepped hole is provided with multiple stepped holes. The design of multiple stepped holes allows for precise positioning through different steps during the assembly process. This multi-level positioning method can reduce assembly errors and ensure the precise connection between the guide device and the photovoltaic glass and other components of the cleaning machine. At the same time, the positioning bolts can be quickly removed and the position of the guide wheel can be changed without stopping the machine, facilitating the stable installation of the guide wheel base. The worn contact surface can be moved, and the unworn contact surface can continue to be used. This design increases the service life of the guide wheel, reduces the frequency of replacement, and improves the equipment's utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is described in further detail below with reference to the accompanying drawings:

[0032] See also Figure 1-3 The utility model provides a photovoltaic glass guide device, including a base connecting plate 1, a transition plate 2, a guide wheel base 3 and a guide wheel 6.

[0033] It should be noted that the base connecting plate 1 of the present invention is an L-shaped structure, and is provided with a strip hole 4. The base connecting plate 1 is made of PVC material, preferably with a thickness of 8mm. The width of the strip hole 4 is 6mm, and the length of the strip hole 4 can be set according to actual needs.

[0034] The transition plate 2 is a two-sided vertical structure. One side has a strip hole 4 connected to the base connecting plate 1, and the other side has a stepped hole 5. The transition plate 2 is made of PVC, preferably 8 mm thick. The width of the strip hole 4 is 6 mm, and the length of the strip hole 4 can be adjusted according to actual needs. The transition plate 2 is connected to the guide wheel base 3 through the stepped hole 5. The stepped hole 5 is provided with multiple stepped holes, each with a diameter of 8 mm. The guide wheel base 3 is connected to the stepped hole 5 with bolts made of M6*30 stainless steel (SUS304). The guide wheel base 3 is equipped with a guide wheel 6. The strip hole 4 on the base connecting plate 1 is connected to the strip hole 4 on the transition plate 2. The guide wheel 6 is made of high-performance polyetheretherketone (PEEK), known for its excellent wear resistance, corrosion resistance, and mechanical strength, making it well suited for use in the harsh environment of photovoltaic glass cleaning machines. Guide wheel 6 is equipped with a deep groove ball bearing, a type widely used in various mechanical devices for its excellent load-bearing capacity and rotational precision. To ensure stable operation, guide wheel 6 is fixed to guide wheel base 3, which securely positions guide wheel 6 via a stepped shaft. The stepped shaft design not only provides the necessary support but also, through precise dimensional matching, ensures stability during high-speed rotation.

[0035] In order to further prevent the guide wheel 6 from unnecessary movement in the axial direction, which would affect the cleaning accuracy and stability, a retaining spring is provided at the top of the stepped shaft, which effectively limits the axial movement of the guide wheel 6 and ensures its smooth operation on the predetermined track.

[0036] The inner and outer diameters and thickness of the guide wheel 6 are customized based on the standard dimensions of a 6002 deep groove ball bearing to ensure a perfect match. To further extend the life of the guide wheel 6, its height has been slightly adjusted to be slightly higher than the standard height of a 6002 deep groove ball bearing, specifically within a range of 25-30mm. This increases the contact area between the guide wheel and the edge of the photovoltaic glass, dispersing contact stress and thus reducing wear and extending its service life.

[0037] The assembly process of the utility model is:

[0038] First, fix the base connecting plate 1 at a predetermined position of the cleaning machine, connect it to the fixing frame of the cleaning machine with bolts, adjust the position according to actual needs and tighten the bolts.

[0039] Next, align the side of the transition plate 2 with the strip hole 4 with the base connecting plate 1 , and use bolts to pass through the strip holes 4 of both for preliminary fixation.

[0040] Then, align the prefabricated hole of the guide wheel base 3 with the stepped hole 5 of the transition plate 2, insert and tighten the fixing bolts from the other side of the transition plate to ensure that the guide wheel base 3 is firmly installed.

[0041] Finally, install the guide wheel 6 on the guide wheel base 3 and adjust the bearing clearance to ensure that the guide wheel can rotate smoothly.

[0042] The working process / working principle of this utility model is as follows:

[0043] During the photovoltaic glass cleaning process, the glass moves along a predetermined path, guided and supported by guide wheels 6, ensuring smooth and accurate passage through the cleaning area. The wear resistance and flexibility of guide wheels 6 effectively reduce friction and wear between the glass and the guide wheels, while also improving guidance accuracy and stability. The design of the strip holes 4 and stepped holes 5 makes the entire guide device flexible and easy to install and adjust within the cleaning machine, easily adapting to different types and sizes of photovoltaic glass and different cleaning process requirements.

[0044] The front and rear adjustment of the guide wheel 6 is completed by the strip hole 4, and the upper and lower position quick adjustment of the guide wheel 6 is completed by the stepped hole 5. The number and spacing of the guide wheels 6 are selected according to the length of the cleaning machine unit and the size of the processed photovoltaic glass 7, so that the overall direction of the photovoltaic glass 7 can be corrected to ensure that the photovoltaic glass 7 is transported in a straight line inside the cleaning machine without deviation.

[0045] The photovoltaic glass guide device of the present invention is connected to the cleaning machine base through a base connecting plate 1, and a transition plate 2 connects the base connecting plate 1 to the guide wheel base 3. The connection between the transition plate 2 and the base connecting plate 1 is provided with a strip hole 4 to facilitate the adjustment of the front and rear positions. The connection between the transition plate 2 and the guide wheel base 3 is provided with a stepped hole 5 to facilitate the quick adjustment of the upper and lower positions of the guide wheel 6. The rest of the installation part is the same as the existing guide wheel installation method. Through the multi-step stepped hole 5, the positioning bolts can be quickly disassembled without stopping the machine to change the position of the guide wheel 6. The multi-step design can move the contact surface after wear, and the unworn contact surface can continue to be used. This design increases the service life of the guide wheel 6, reduces the frequency of replacement, and improves the utilization rate of the equipment. This device is highly practical and widely used. The overall device is easy to use, simple to maintain and adjust, and can be easily disassembled and replaced.

[0046] The photovoltaic glass guide device of the utility model can also be installed on the entrance conveyor belt device of the photovoltaic glass tempering furnace to ensure that the glass does not deviate when entering the tempering furnace.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
