Description

Technical Field

[0001] This utility model relates to the field of adjustment mechanism technology, and in particular to a wear-resistant guide wheel angle adjustment mechanism for photovoltaic equipment. Background Technology

[0002] The core function of wear-resistant guide rollers is concentrated in the silicon wafer manufacturing stage of the photovoltaic industry chain, especially in the "multi-wire cutting" process. Multi-wire cutting requires the high-speed movement of ultra-fine cutting wires to cut silicon ingots. The guide rollers need to precisely support the cutting wires. Photovoltaic silicon wafer production is a large-scale mass production scenario, and equipment downtime for maintenance directly affects production capacity. The service life of wear-resistant guide rollers is much longer than that of ordinary guide rollers (typically thousands of hours), which can significantly reduce the frequency of guide roller replacement, reduce downtime and consumable costs, and ensure the continuous and stable operation of the production line.

[0003] A self-aligning guide wheel mechanism for a multi-wire cutting machine, with authorized publication number CN217670323U, includes a cantilever, a corner assembly fixing frame sleeved and fixed on the cantilever, and a self-aligning guide wheel fixed on the corner assembly fixing frame. One end of the cantilever is fixed with an adjustment plate; a swing wheel frame shaft passes through the corner assembly fixing frame; the self-aligning guide wheel includes a swing body sleeved on the swing wheel frame shaft, a swing wheel frame on one side of the swing body, a first guide wheel axle located on the swing wheel frame, and a guide wheel fixedly sleeved on the first guide wheel axle. Compared with existing technologies, this invention, through the rotatable structure of the swing wheel frame and the self-aligning guide wheel, can automatically adjust the guide wheel angle, enabling the guide wheel before the multi-wire cutting machine winds around the roller to automatically adjust to a suitable angle under wire tension. This facilitates equipment use, saves winding time, and avoids the problems of insufficient precision in traditional guide wheel adjustment and wire detachment.

[0004] Regarding the aforementioned technologies, the existing adjustment mechanisms have the following drawbacks: as the wear resistance of the guide wheel deteriorates, the surface will wear down rapidly, forming grooves, which will cause the cutting line to deviate or the tension to fluctuate, directly resulting in uneven silicon wafer thickness or even breakage. Therefore, this utility model provides a wear-resistant guide wheel angle adjustment mechanism for photovoltaic equipment. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1: Reference Figure 1-4The diagram illustrates a wear-resistant guide wheel angle adjustment mechanism for photovoltaic equipment, comprising a support frame 1. The support frame 1 serves as the mounting foundation and load-bearing body of the entire adjustment mechanism, providing stable support for each component and ensuring the overall structural integrity of the mechanism. A tension adjustment component is installed on the outer side of the support frame 1 to adjust the tension during wire transmission, ensuring smooth transmission. The tension adjustment component includes multiple first guide wheels 5 and second guide wheels 6 installed on the outer side of the support frame 1. These two components work together to guide the wire transmission, ensuring the material moves along a preset path. A pair of hydraulic push rods 7 are fixedly connected to the outer side of the support frame 1, serving as the power source for tension adjustment. The power is transmitted through the output end... The extension and retraction drive the movement of subsequent components; the output end of the hydraulic push rod 7 is fixedly connected to the push plate 8, which plays a role in force transmission, synchronously transmitting the power of the hydraulic push rod 7 to the sliding rod 9; the outer sides of multiple first guide wheels 5 and second guide wheels 6 are all fixedly connected to the sliding rod 9, which is used to drive the guide wheels to move along the slide groove 13 to achieve position adjustment; the outer side of the support frame 1 is provided with a slide groove 13 that matches the sliding rod 9, providing guidance for the sliding rod 9, ensuring its stable movement trajectory, and thus ensuring accurate adjustment of the guide wheel angle; the sliding rod 9 on one side is fixedly connected to the push plate 8 on the same side, so that the push plate 8 can synchronously drive the sliding rod 9 and the guide wheel on the same side to move; the push plate A cooling and heat-reducing component is provided on the outer side of the push plate 8 to reduce the heat generated by friction of the guide wheel and extend its service life. The cooling and heat-reducing component includes an air pump 12 fixedly connected to the outer side of the push plate 8, which serves as a cooling air source to provide a continuous airflow for the cooling process. The output end of the air pump 12 is fixedly connected to an air distribution pipe 11 with multiple air outlets to achieve airflow diversion and uniform distribution. Multiple interconnected vent pipes 10 are fixedly connected to the outer side of the air distribution pipe 11 to guide the airflow in the air distribution pipe 11 to the guide wheel. The multiple vent pipes 10 located on both sides are respectively connected to the first guide wheel 5 and the second guide wheel 6 to ensure that the airflow is accurately delivered to each guide wheel. The inner sides of the guide wheel 5 and the second guide wheel 6 are provided with spiral vent holes that extend to the outside through the vent pipe 10, allowing the airflow to flow spirally inside the guide wheel, increasing the contact area with the guide wheel and improving the cooling efficiency. At the same time, the spiral structure can prevent the airflow from directly impacting the wire. Multiple first guide wheels 5 and second guide wheels 6 are located on both sides of the support frame 1, forming a symmetrical guide structure, which facilitates the balance adjustment of tension. The outer sides of the first guide wheels 5 and the second guide wheels 6 are coated with a ceramic base coating. The ceramic base coating can improve the wear resistance of the guide wheels, reduce wear during long-term use, and enhance their high temperature resistance, further extending their service life in conjunction with the cooling components.

[0019] Example 2: Reference Figure 1-4Based on the same concept as Embodiment 1 above, this embodiment further proposes that a groove 14 is provided on the outer side of the support frame 1. The groove 14 provides installation space and movement guidance for the deflection rod 3, allowing the deflection rod 3 to deflect stably within the groove 14 and preventing offset or shaking during deflection. A matching deflection rod 3 is provided within the groove 14. The deflection rod 3 is used to receive the power of the motor 4 and drive the traction wheel 2 to achieve angle adjustment. The motor 4 is fixedly connected to the outer side of the support frame 1. The motor 4 serves as a power source, providing stable power for the deflection of the deflection rod 3, ensuring precise and controllable deflection process. The output end of motor 4 is connected to the support frame 1, and the output end of motor 4 is fixedly connected to the deflection rod 3 to realize direct power transmission and reduce power loss. One end of the deflection rod 3 is fixedly connected to the traction wheel 2. The traction wheel 2 is used to cooperate with the traction rope or related traction components. The traction direction can be changed by adjusting the angle to meet the traction needs of different working conditions. The outside of the support frame 1 is provided with a mounting frame for connecting with external equipment. The mounting frame is used to realize the stable connection between the support frame 1 and the external equipment, ensure the installation stability of the entire device during operation, and avoid the device from shifting or failing due to loose connection.

[0020] The working principle of this utility model is as follows: The wire passes sequentially around the traction wheel 2 and then around multiple staggered first guide wheels 5 and second guide wheels 6 in an "S" shape. The tension of the wire is monitored by a tension monitor located on the outside of the support frame 1. If the wire becomes slack, the control motor 4 drives the deflection rod 3 and the traction wheel 2 to deflect, initially tensioning the wire. If the adjustment force is insufficient, the corresponding hydraulic push rod 7 drives the push plate 8, multiple sliding rods 9, and the first guide wheel 5 to move, adjusting the tension of the wire. By performing the same operation to adjust the tension of the wire, the tension of the wire is further adjusted by adjusting the position of multiple second guide wheels 6. The control air pump 12 guides airflow into the spiral vent holes inside the first guide wheels 5 and second guide wheels 6 through the air distribution pipe 11 and multiple vent pipes 10, and the airflow flows out to dissipate heat and cool the first guide wheels 5 and second guide wheels 6.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
