DETAILED DESCRIPTION

[0033] ​​​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0034] An embodiment of a diamond sawing wire electroplating device is provided, as shown in Figures 1 to 12

[0035] An embodiment of a diamond sawing wire electroplating device is provided, as shown in

[0036] Specifically, the electroplating tank 200 is fixedly connected with a support plate 210 at two ends in the first direction, and the current-carrying guide wheel 400 is rotatably installed on the support plate 210.

[0037] Further, the guide wheel 300 is provided with two guide wheels 300, which are sequentially arranged in the first direction and are located in the electroplating tank 200. After the free end of the metal wire 100 is wound around one of the current-carrying guide wheels 400 in the first direction, it is sequentially wound around the two guide wheels 300 downward, and then wound around the other current-carrying guide wheel 400 upward.

[0038] Further, the guide wheel 300 is provided with two guide wheels 300, which are sequentially arranged in the first direction and are located in the electroplating tank 200. After the free end of the metal wire 100 is wound around one of the current-carrying guide wheels 400 in the first direction, it is sequentially wound around the two guide wheels 300 downward, and then wound around the other current-carrying guide wheel 400 upward.

[0039] The embodiment is used in cooperation with the electroplating tank 200, the guide wheel 300 and the two current-carrying guide wheels 400. In use, referring to Figure 3 ​As shown, the metal wire 100 is passed over the current-carrying guide roller 400 on the right side, then wound to the lower side of the guide roller 300, and then pulled out from the current-carrying guide roller 400 on the left side. Under the limiting of the guide roller 300, the metal wire 100 is immersed in the electroplating solution of the electroplating tank 200. When the current-carrying guide roller 400 is electrified with the electroplating solution, the diamond grits in the electroplating solution will be electroplated onto the metal wire 100. The metal wire 100 is continuously unwound and wound by the unwinding roller and the winding roller, and the metal wire 100 is continuously moved from right to left by friction to drive the guide roller 300 to rotate. Since the cross section of the guide roller 300 perpendicular to the axial direction is elliptical, the elliptical structure of the guide roller 300 can limit the metal wire 100 and additionally stir the diamond grits in the electroplating solution when the guide roller 300 rotates. Since the linear speed of the metal wire 100 is constant and the linear speed of the guide roller 300 is the same as that of the metal wire 100, the guide roller 300 with an elliptical structure stirs in a variable speed manner during rotation, further enhances the uniformity of stirring, and makes the diamond grits in the electroplating solution more uniformly distributed, which helps to improve the electroplating quality.

[0040] In a further embodiment, the long sides of the two guide rollers 300 are perpendicular to each other in the initial state.

[0041] Referring to Figure 3 As shown, the long side of the guide roller 300 on the left side is arranged in the first direction, and the long side of the guide roller 300 on the right side is arranged in the vertical direction. This arrangement enables the guide roller 300 on the left side and the guide roller 300 on the right side to alternately move the metal wire 100 up and down during rotation, so that the tension of the metal wire 100 is more consistent.

[0042] In a further embodiment, the current-carrying guide roller 400 and the guide roller 300 are both provided with guide grooves 500. The guide grooves 500 are uniformly distributed in the circumferential direction of the corresponding current-carrying guide roller 400 and guide roller 300. The movement of the metal wire 100 is limited by the guide grooves 500.

[0043] The guide roller 300 includes a shaft 310 and a plurality of wheel bodies 320. The shaft 310 is rotatably installed in the electroplating tank 200, and the plurality of wheel bodies 320 are sequentially and spacedly arranged in the first direction on the shaft 310 and can rotate with the shaft 310. The guide grooves 500 are provided on the wheel bodies 320, and there is one guide groove 500 on each wheel body 320. The guide groove 500 is a circular groove.

[0044] Alternatively, in another possible embodiment, the guide groove 500 on each wheel body 320 includes two first groove sections 510 and two second groove sections 520. The two first groove sections 510 and the two second groove sections 520 are sequentially arranged in the circumferential direction of the wheel body 320, and the first groove sections 510 and the second groove sections 520 are alternately distributed in the circumferential direction of the wheel body 320. The first groove section 510 is an arc section, and the two first groove sections 510 are sequentially arranged in the first direction. The second groove section 520 is obliquely arranged and communicates with the two first groove sections 510. The second groove section 520 is located on one side of the short side of the wheel body 320. The second groove section 520 is provided with a guide slope 530 on both sides in the first direction. The second groove sections 520 of two wheel bodies 320 arranged adjacent in the first direction are arranged face to face in the axial direction of the wheel body 320.

[0045] The power guide wheel 400 includes a rotating wheel 410 and a plurality of guide rings 420. The rotating wheel 410 is rotatably mounted on the electroplating tank 200, and the plurality of guide rings 420 are sequentially and spacedly arranged in the first direction on the rotating wheel 410 and coaxial with the rotating wheel 410. The guide ring 420 is in key groove cooperation with the rotating wheel 410, so that the guide ring 420 can rotate with the rotating wheel 410 and can move relative to the rotating wheel 410 in the first direction. The guide groove 500 is formed on the guide ring 420, and two guide grooves 500 are formed on each guide ring 420. The distance between the two metal wires 100 on the same guide ring 420 in the first direction is less than the distance between the two metal wires 100 on the two guide rings 420 arranged adjacent in the first direction. The guide ring 420 is used to separate every two metal wires 100 to prevent interference between the metal wires 100 on different guide rings 420. It should be particularly noted that the axial displacement of the guide ring 420 is not large, and is only used to adapt to the axial displacement of the metal wire 100 from the first groove section 510 to the second groove section 520.

[0046] Alternatively, in another possible embodiment, the second groove section 520 is provided with a guide wheel 540 at both ends in the circumferential direction of the wheel body 320. The guide wheel 540 is rotatably mounted on the wheel body 320 and is perpendicular to the axis of the wheel body 320. The guide wheel 540 is used to guide the metal wire 100.

[0047] In this embodiment, the guide groove 500 is provided with two first groove sections 510 and two second groove sections 520. During the movement of the metal wire 100 and the rotation of the guide wheel 300, when the metal wire 100 reaches the junction of the first groove section 510 and the second groove section 520, the metal wire 100 still has a tendency to continue to be arranged around the path. Therefore, the metal wire 100 will be in contact with the guide slope 530, and will gradually slide into the second groove section 520 under the guidance of the guide slope 530.

[0048] The setting is because when the guide wheel 300 rotates to stir the electroplating solution, the rotating resistance of the guide wheel 300 is relatively large when the guide wheel 300 is arranged from the long side in the first direction to the long side in the vertical direction. Compared with arranging the guide groove 500 as a circle, the metal wire 100 can produce bending at the junction of the first groove segment 510 and the second groove segment 520, increase the tightness of the metal wire 100 at the junction of the first groove segment 510 and the second groove segment 520, and then increase the friction between the guide groove 500 and the metal wire 100, avoid sliding friction between the guide groove 500 and the metal wire 100, and affect the normal rotation of the guide wheel 300.

[0049] In a further embodiment, two cutters 330 are arranged on each wheel body 320, and the two cutters 330 are arranged in sequence in the first direction. Two inclined guide grooves 340 are arranged on the wheel body 320, and the inclined guide grooves 340 are arranged one by one with the cutters 330. The inclined guide grooves 340 are arranged obliquely relative to the vertical direction. The two ends of the inclined guide groove 340 are referred to as the tail end and the top end, respectively. The tail end is located on the side close to the axis of the wheel body 320 in the radial direction of the wheel body 320, and the tail ends of the two inclined guide grooves 340 on the same wheel body 320 are close to each other, and the top ends are far away from each other. In the initial state, each cutter 330 is located at the tail end of the inclined guide groove 340 arranged thereon, and each cutter 330 can slide out from the tail end to the top end of the inclined guide groove 340 arranged thereon, and cut the metal wire 100 on the wheel body 320 arranged adjacent to the wheel body 320 in the first direction.

[0050] Among them, the first elastic member 370 is arranged between the wheel body 320 and the wheel shaft 310, and the first elastic member 370 is a volute spring. Each cutter 330 is abutted on the wheel shaft 310 through a top rod 350, the top rod 350 is arranged in the radial direction of the wheel body 320, and can only move in the radial direction of the wheel body 320. The wheel shaft 310 is provided with an ejection groove 360 around the circumferential direction thereof. The two ends of the ejection groove 360 are referred to as the first end and the second end, respectively. In the circumferential direction of the wheel shaft 310, the depth of the ejection groove 360 gradually decreases from the first end to the second end. In the initial state, the top rod 350 is abutted with the first end of the ejection groove 360.

[0051] Specifically, each cutter 330 is connected with the wheel body 320 through a second elastic member 380, and the second elastic member 380 is a spring. The wheel body 320 is provided with a limiting groove 321 arranged in the radial direction of the wheel body 320. The top rod 350 is slidingly installed in the limiting groove 321, so that the top rod 350 can only move in the radial direction of the wheel body 320.

[0052] In the process of work, when a metal wire 100 suddenly breaks, the metal wire 100 will inevitably be wound on the adjacent metal wire 100 after breaking, and then a chain reaction occurs. The embodiment is provided with a cutter 330 on the wheel body 320, as shown in Figure 6 When the metal wire 100 on the right wheel body 320 suddenly breaks, the volute spring between the wheel body 320 and the wheel shaft 310 will reverse the wheel body 320 relative to the wheel shaft 310, so that the ejection groove 360 is in abutment with the ejector rod 350 at the second end. In this process, the ejector rod 350 will move in the radial direction of the wheel shaft 310, and the cutter 330 will slide along the tail end of the corresponding inclined guide groove 340 to the top end, so that the cutter 330 on the right wheel body 320 extends to the left, until the cutter 330 cuts off the metal wire 100 on the left wheel body 320. That is, the cutter 330 moves from the state shown by the dashed line to the state shown by the solid line. Figure 6

[0053] In this process, the operator can power off the electroplating device to stop the entire electroplating device, avoid affecting other metal wires 100, and then manually process the broken wire, thereby reducing the negative impact of the broken metal wire 100.

[0054] The application also provides an electroplating process of the electroplating device of the diamond sawing wire, which utilizes the electroplating device of the diamond sawing wire, and includes the following steps:

[0055] S10, after winding the metal wire 100 on one of the current guide rollers 400 in the first direction, winding the metal wire 100 on the guide roller 300 in the downward direction, and then winding the metal wire 100 on the other current guide roller 400 in the upward direction, and powering the current guide roller 400 and the electroplating solution in the electroplating tank 200;

[0056] S20, moving the metal wire 100 in the first direction and driving the guide roller 300 to rotate around its own axis.

[0057] The above description is only a preferred embodiment of the application and is not intended to limit the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application shall be included in the protection scope of the application.​
