Description

Technical Field

[0001] This utility model belongs to the technical field of diamond wire equipment, specifically referring to a conductive cathode roller for multi-wire diamond wire production. Background Technology

[0002] Electroplated diamond wire is widely used in silicon cutting due to its excellent cutting efficiency. During the abrasion process of the diamond wire, the cathode roller acts as a conductor, and the diamond wire is wound around the conductive cathode roller during abrasion.

[0003] However, most existing conductive cathode rollers used in multi-line diamond wire production directly wind diamond wire, making the entire cathode roller energized. This can easily lead to leakage and misalignment of the diamond wire, affecting multi-line production. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model proposes a conductive cathode roller for multi-wire diamond wire production, which effectively solves the problems that most conductive cathode rollers for multi-wire diamond wire production directly wind diamond wire, making the entire cathode roller energized and prone to leakage, and that diamond wire is prone to misalignment and winding, affecting multi-wire production.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a conductive cathode roller for diamond wire multi-wire production, including a fixed shaft, a cathode roller structure, and a rotating structure. The cathode roller structure is disposed on the fixed shaft, and the rotating structure is disposed on the fixed shaft. The cathode roller structure includes a metal ring, a cathode cable, an arc-shaped electrode sheet, a connecting post, an electrode post, a spring, a U-shaped groove, and an insulating rubber ring. The metal ring is wrapped around the fixed shaft, the cathode cable passes through the fixed shaft and is fixedly disposed on the metal ring, the arc-shaped electrode sheet is rotatably disposed around the metal ring, the connecting post is fixedly disposed above the arc-shaped electrode sheet, the electrode post is inserted into the connecting post, one end of the spring is fixedly disposed on the connecting post and the other end is fixedly disposed inside the electrode post, the U-shaped groove is fixedly disposed at the top of the electrode post, and the insulating rubber ring passes through the electrode post and wraps around the U-shaped groove.

[0006] Preferably, the rotating structure includes an inner shell, a cage, an outer shell, and balls. The inner shell is fixedly mounted on a fixed shaft. The cage is rotatably mounted on the outside of the inner shell. The outer shell is rotatably mounted on the outside of the cage and fixedly mounted on the inside of an insulating rubber ring. The balls pass through the insulating rubber ring and roll between the inner shell and the outer shell.

[0007] To achieve a more stable connection, six sets of electrode posts are arranged with a 60-degree interval between them.

[0008] To achieve the goal of reducing friction more quickly, the arc-shaped electrode is designed in an arc shape.

[0009] Furthermore, the insulating rubber ring is made of insulating rubber material.

[0010] To achieve good conductivity, the metal ring, arc-shaped electrode, connecting post, electrode post, spring, and U-shaped groove are all made of brass.

[0011] The beneficial effects of this utility model using the above structure are as follows: The conductive cathode roller for multi-wire diamond wire production proposed in this solution insulates the U-shaped groove with an insulating rubber ring, and connects the current through the arc-shaped electric sheet, connecting column and metal ring to achieve local energization, single-wire guidance and improve safety.

[0016] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, this utility model proposes a conductive cathode roller for diamond wire multi-wire production, comprising a fixed shaft 1, a cathode roller structure 2, and a rotating structure 3. The cathode roller structure 2 is mounted on the fixed shaft 1, and the rotating structure 3 is also mounted on the fixed shaft 1. The cathode roller structure 2 includes a metal ring 4, a cathode cable 5, an arc-shaped electrode sheet 6, a connecting post 7, an electrode post 8, a spring 9, a U-shaped groove 10, and an insulating rubber ring 11. The metal ring 4 is wrapped around the fixed shaft 1, the cathode cable 5 passes through the fixed shaft 1 and is fixedly mounted on the metal ring 4, and the arc-shaped electrode sheet 6 is rotatably mounted around the metal ring 4. The arc-shaped electrode 6 is arranged in an arc shape. The connecting post 7 is fixed above the arc-shaped electrode 6. The electrode post 8 is inserted into the connecting post 7. There are six sets of electrode posts 8, which are spaced sixty degrees apart. One end of the spring 9 is fixed to the connecting post 7 and the other end is fixed inside the electrode post 8. The U-shaped groove 10 is fixed to the top of the electrode post 8. The metal ring 4, the arc-shaped electrode 6, the connecting post 7, the electrode post 8, the spring 9, and the U-shaped groove 10 are all made of brass. The insulating rubber ring 11 passes through the electrode post 8 and wraps around the U-shaped groove 10. The insulating rubber ring 11 is made of insulating rubber.

[0019] like Figure 1 and Figure 3 As shown, the rotating structure 3 includes an inner shell 12, a retainer 13, an outer shell 14, and a ball bearing 15. The inner shell 12 is fixedly mounted on the fixed shaft 1. The retainer 13 is rotatably mounted on the outside of the inner shell 12. The outer shell 14 is rotatably mounted on the outside of the retainer 13 and fixedly mounted on the inside of the insulating rubber ring 11. The ball bearing 15 passes through the insulating rubber ring 11 and rolls between the inner shell 12 and the outer shell 14.

[0020] In practical use, the diamond wire is guided from the U-shaped groove 10 into the sanding system. At this time, the diamond wire contacts the U-shaped groove 10 and conducts electricity. The cathode current is then transmitted through the cathode cable 5 to the metal ring 4, and then through the metal ring 4 to the arc-shaped electrode 6 and the connecting post 7, and finally to the U-shaped groove 10 on the electrode post 8. Thus, the U-shaped groove 10 transmits the cathode current to the diamond wire, allowing the diamond wire to adsorb metal cations in the electroplating solution for sanding. The diamond wire pulls the insulating rubber ring 11 on the U-shaped groove 10 to rotate, which in turn causes the electrode post 8 inside the insulating rubber ring 11 to drive the connecting post 7 to rotate. As a result, the arc-shaped electrode 6 on the connecting post 7 rotates around the metal ring 4. At this time, the spring 9 pushes the arc-shaped electrode 6 on the connecting post 7 to press against the metal ring 4, connecting and energizing the wire to achieve stable energization for sanding. At the same time, the U-shaped groove 10 limits and guides a group of diamond wires to prevent entanglement when producing multiple diamond wires. The above is the entire process of using the conductive cathode roller for multi-wire diamond wire production.
