Description

Technical Field

[0001] This utility model relates to the field of electroplated diamond wire saw processing technology, and in particular to a guide wheel device for electroplated diamond wire saw equipment. Background Technology

[0002] Diamond wire saws are widely used in the photovoltaic silicon wafer cutting industry. Diamond wire saws are a key auxiliary material in silicon wafer cutting. Therefore, the production of diamond wire saws needs to improve the stability of the product process and reduce the number of defective products in the product process, thereby improving product production efficiency and reducing production costs.

[0003] In the existing technology, electroplated diamond wire saws sometimes experience problems such as wire rotation and wire damage from guide wheels during the production process, which affects the product quality of the electroplated diamond wire saw. Summary of the Invention

[0004] The technical problem this invention aims to solve is: how to prevent the steel wire from rotating on its own and the guide wheel from damaging the wire during the production process of electroplated diamond wire saws.

[0005] To solve the above-mentioned technical problems, this utility model provides a guide wheel device for an electroplated diamond wire saw, including a bracket, a guide wheel and a shaft. One end of the shaft is connected to the bracket, and the other end of the shaft is connected to the guide wheel. The guide wheel is rotatably mounted on the bracket via the shaft. The guide wheel has a hollowed-out groove that passes through the guide wheel along its axial direction. A flexible ring is fitted on the outer circumferential surface of the guide wheel.

[0006] Furthermore, the flexible ring is a polyurethane rubber ring.

[0007] Furthermore, the circumferential edges of both end faces of the guide wheel are provided with flanges, the flanges extending radially out of the outer circumferential surface of the guide wheel, and the flexible ring is located between the two flanges.

[0008] Furthermore, the guide wheel has a mounting groove at its center, and a bearing is installed in the mounting groove. The guide wheel is rotatably connected to the shaft through the bearing.

[0009] Furthermore, a spring retainer is provided in the mounting groove, and the spring retainer abuts against the outer ring of the bearing.

[0010] Furthermore, the shaft body is provided with a countersunk screw at the end of the mounting groove, and the countersunk screw abuts against the inner ring of the bearing.

[0011] Furthermore, the end of the shaft away from the guide wheel is provided with an external thread, and a nut is threadedly connected to the external thread. The upper end of the bracket is provided with a U-shaped groove, and the shaft passes through the U-shaped groove. The shaft is provided with a shoulder, and the shoulder is located on both sides of the bracket opposite to the nut.

[0012] Furthermore, the bracket is L-shaped, the U-shaped groove is located at the upper end of the bracket and the U-shaped groove extends through the bracket laterally, and the lower end of the bracket is provided with an elongated hole that extends through the bracket longitudinally.

[0013] The guide wheel device for electroplated diamond wire saw equipment provided by the above technical solution has the following advantages compared with the prior art: By setting a hollow groove in the guide wheel, the hollow groove runs through the guide wheel along the axial direction of the guide wheel, making the hollow guide wheel lighter and easier to rotate. The steel wire drives the guide wheel to rotate more flexibly, preventing the steel wire from being damaged due to the guide wheel's inflexible rotation during steel wire transmission. By sleeved a flexible ring on the outer circumference of the guide wheel, the flexible ring provides greater friction when in contact with the steel wire, which can prevent the steel wire from rotating on its own. The flexible ring is flexible enough to protect the steel wire and will not scratch the steel wire, thereby further preventing damage to the wire. Attached Figure Description

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 based on the specific circumstances.

[0020] like Figure 1 and Figure 2 As shown, the present invention provides a guide wheel device for an electroplated diamond wire saw, including a bracket 1, a guide wheel 2 and a shaft 3. One end of the shaft 3 is connected to the bracket 1, and the other end of the shaft 3 is connected to the guide wheel 2. The guide wheel 2 is rotatably mounted on the bracket 1 via the shaft 3. The guide wheel 2 is provided with a hollow groove 21, which penetrates the guide wheel 2 along the axial direction of the guide wheel 2. A flexible ring 4 is sleeved on the outer circumferential surface of the guide wheel 2.

[0021] During use, the bracket 1 can be fixedly mounted on the electroplated diamond wire saw equipment. The guide wheel 2 can rotate relative to the bracket 1. When the wire is transmitted, it contacts the flexible ring 4 on the outer circumference of the guide wheel 2. By setting a hollow groove 21 on the guide wheel 2, the hollow groove 21 passes through the guide wheel 2 along the axial direction of the guide wheel 2. The hollow guide wheel 2 is lighter and rotates more easily. The wire drives the guide wheel 2 to rotate more flexibly, preventing the wire from being damaged due to the guide wheel 2's inflexible rotation during wire transmission. By sleeved with a flexible ring 4 on the outer circumference of the guide wheel 2, the flexible ring 4 provides greater friction when in contact with the wire, which can prevent the wire from rotating on its own. The flexible ring 4 is flexible and can protect the wire, preventing it from being scratched, thus further preventing damage to the wire.

[0022] In some embodiments, the flexible ring 4 is a polyurethane rubber ring, which has a certain degree of elasticity.

[0023] In some embodiments, the circumferential edges of both end faces of the guide wheel 2 are provided with flanges 22, which extend radially out of the outer circumferential surface of the guide wheel 2, and the flexible ring 4 is located between the two flanges 22. The flanges 22 can support the flexible ring 4 and prevent it from shifting.

[0024] In some embodiments, the guide wheel 2 has a mounting groove at its center, and a bearing 5 is provided in the mounting groove. The guide wheel 2 is rotatably connected to the shaft 3 through the bearing 5. Specifically, the mounting groove is circular and is fixedly fitted onto the outer ring of the bearing 5, while the inner ring of the bearing 5 is fixedly fitted onto the shaft 3.

[0025] In some embodiments, as Figure 2 As shown, a spring retainer 6 is provided in the mounting groove, and the spring retainer 6 abuts against the outer ring of the bearing 5. The spring retainer 6 can prevent the outer ring of the bearing 5 from shifting.

[0026] In some embodiments, as Figure 2 As shown, the shaft 3 has a countersunk screw 7 at its end in the mounting groove, which abuts against the inner ring of the bearing 5. Specifically, the end of the shaft 3 has a threaded hole, and the countersunk screw 7 is threaded into this hole. The head of the countersunk screw 7 abuts against the inner ring of the bearing 5 to limit the inner ring of the bearing 5. When the guide wheel 2 rotates, the shaft 3 and the bracket 1 remain relatively fixed, while the guide wheel 2 rotates relative to the shaft 3.

[0027] In some embodiments, as Figure 1 As shown, the end of the shaft 3 away from the guide wheel 2 has an external thread, which is threaded to a nut 8. The upper end of the bracket 1 has a U-shaped groove 11, through which the shaft 3 passes. The shaft 3 has a shoulder, which is located on both sides of the bracket 1 opposite to the nut 8. Specifically, the U-shaped groove 11 facilitates the installation of the shaft 3 and the bracket 1. The diameter of the shoulder is larger than the width of the U-shaped groove 11. The shoulder and the nut 8 clamp the bracket 1, thereby fixing the shaft 3 to the bracket 1.

[0028] In some embodiments, as Figure 1As shown, the bracket 1 is L-shaped, with a U-shaped groove 11 located at the upper end of the bracket 1, extending horizontally through the bracket 1. An elongated hole 12 is provided at the lower end of the bracket 1, extending longitudinally through the bracket 1. The U-shaped groove 11 allows adjustment of the vertical position of the shaft 3 and the guide wheel 2, thereby adjusting the height of the guide wheel 2 as needed. The bracket 1 is fixed to the electroplated diamond wire saw equipment through the elongated hole 12, and its horizontal position can be adjusted accordingly, thereby adjusting the position of the guide wheel 2 as needed. The bracket 1 allows for convenient and quick adjustment of the height and lateral position of the guide wheel 2, ensuring the wire is in the optimal position on the guide wheel 2. The bracket 1 is made of stainless steel.

[0029] Specifically, the axis of the shaft 3 is set horizontally, and the guide wheel 2 is set coaxially with the shaft 3. When the flexible ring 4 wears out after a certain period of use, the position of the guide wheel 2 can be adjusted by the bracket 1 so that the rigid wire is in a new position of the flexible ring 4. The flexible ring 4 can be used multiple times, so there is no need to replace the guide wheel 2, thus saving costs.

[0030] In summary, this utility model provides a guide wheel device for an electroplated diamond wire saw. This device is characterized by high versatility, ease of use, and reusability, which improves production quality. This device enables standardized operation of production equipment, reduces the risk of damage to the diamond wire due to the self-rotation of the wire during production and the failure to replace the guide wheel 2 in a timely manner, thereby improving product quality and production efficiency and reducing production costs.

[0031] 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.
