Technical Field
[0001] The utility model belongs to the technical field of diamond wire production, and in particular relates to a cathode roller for diamond wire plating. Background Art
[0002] Diamond wire is the abbreviation of diamond cutting wire. Many hard materials in industry, such as silicon wafers, are cut and processed by diamond wire. The winding device of the electroplated diamond wire production equipment commonly used in the market mainly uses a cylindrical roller as the cathode conductive device, commonly known as the cathode roller. The existing new continuous electroplating cathode roller still has certain defects when used, such as:
[0003] Currently, most cathode roller wire troughs are V-shaped. During the production of diamond wire, when the steel wire swings, it moves outward along the inner curved side wall of the wire trough, and there is a possibility of separation from the cathode conductive rod on the inside, resulting in poor electroplating effect. The electroplating time can only be extended, affecting production efficiency. Summary of the invention
[0004] The utility model aims to solve the problem that most of the current cathode roller wire passing grooves are of V-shaped structure. During the diamond wire production process, when the steel wire swings, it moves outward along the inner arc-shaped side wall of the wire passing groove, and there is a situation where it is separated from the cathode conductive rod inside, resulting in poor electroplating effect, which can only prolong the electroplating time and affect the production efficiency. A cathode roller for diamond wire plating is provided, which is configured by configuring the outer side of the wire passing groove to be an outer groove with a rectangular cross-section, and the inner side to be an inner groove with a V-shaped cross-section, and the cathode conductive rod passes through the inner groove, so that the swing of the steel wire in the wire passing groove will not cause the other inner conductive rods to separate, thereby ensuring the electroplating effect.
[0005] In order to achieve the above purpose, the technical solution of the utility model is:
[0006] A cathode roller for diamond wire plating comprises two relatively arranged covers, a plurality of wire passing disks are fixedly arranged between the two covers, a plurality of wire passing grooves are opened on the outer circumference of the wire passing disks, the wire passing grooves comprise inner grooves and outer grooves which are connected, the cross section of the inner groove is triangular, and the cross section of the outer groove is rectangular, cathode holes, limiting holes and mounting holes are opened on the end surface of the wire passing disk from outside to inside in sequence, the cathode holes and limiting holes are both arranged in multiples and are evenly arranged along the circumference of the wire passing disk, the mounting hole is coaxially arranged with the wire passing disk, annular grooves are coaxially opened on the end surfaces of both ends of the wire passing disk, through holes and connecting holes are opened in sequence from inside to outside on the inner side surface of the annular groove, the through holes and connecting holes are both arranged in multiples around the mounting hole, a transmission shaft is passed through the mounting hole, the transmission shaft is fixedly connected to the cover body, a conductive rod is passed through the cathode hole, the conductive rod passes through multiple inner grooves in sequence, the limit of the steel wire is ensured by the inner groove, the inner groove cooperates with the outer groove, and when the steel wire swings, its contact with the conductive rod is ensured, thereby ensuring the electroplating effect.
[0007] Preferably, one end of the transmission shaft penetrates through the cover body and is connected to a power device, which is used to drive the transmission shaft to rotate, and the transmission shaft drives the cover body and the wire passing disc to rotate.
[0008] Preferably, a limiting rod is inserted into the limiting hole. Nuts are threadedly connected to both ends of the limiting rod and the conductive rod after they protrude from the cover body. The limiting rod ensures the positioning of multiple wire passing discs and prevents the wire passing discs from rotating when the conductive rod is installed.
[0009] Preferably, adjacent wire passing discs are fixedly connected by a plurality of bolts. The bolts pass through corresponding connection holes on adjacent wire passing discs and are threadedly connected with nuts, ensuring the fixed connection between adjacent wire passing discs.
[0010] Preferably, the middle part of the conductive rod is a smooth rod and the two ends are provided with threads. The middle part of the limiting rod is a smooth rod and the two ends are provided with threads. The smooth middle part of the conductive rod ensures the conductive effect when contacting the steel wire and reduces the influence of friction.
[0011] By the above technical solutions, the beneficial effects of the present utility model are as follows:
[0012] 1. The present utility model opens a wire passing groove on the outer side of the wire passing disc for winding the steel wire, and sets the inner groove to have a triangular cross-section, and the conductive rod penetrates through the inner groove, so that when the steel wire swings in the wire passing groove, it can contact the conductive rod at any time, ensuring the conductive effect, and further ensuring the electroplating effect, and avoiding problems such as poor electroplating effect or failure to electroplate during electroplating.
[0013] 2. The present utility model combines two wire passing discs in pairs and fixedly connects them by bolts, and then limits and connects them in series by a limiting rod.

[0014] 3. The present utility model opens a plurality of through holes on the wire passing disc, effectively reducing the overall weight of the cathode roller composed of the wire passing discs and saving materials.
[0015] 4.

[0016] 5. The present utility model drives the cover body to rotate through the transmission shaft, drives the wire passing disc to rotate to realize the overall rotation of the cathode roller. At the same time, by tightening and fixing the nuts at both ends of the limiting rod and the conductive rod, the limiting and fixed connection of the wire passing disc and the cover body are ensured, and the overall rotation effect of the cathode roller is ensured.

[0029] The present utility model will be further described below in conjunction with the attached drawings and specific embodiments
[0030] Such as Figures 1 to 11As shown in the figure, this embodiment provides a cathode roller for diamond wire plating, which includes two relatively arranged cover bodies 1. A plurality of wire passing discs 2 are fixedly arranged between the two cover bodies 1. There are 8 wire passing discs 2. Adjacent two wire passing discs 2 are fixedly connected by a plurality of bolts 15. Among them, two wire passing discs 2 are taken as a group, and the two wire passing discs 2 in a group are fixedly connected by bolts 15.
[0031] A plurality of wire passing grooves 3 are formed on the outer periphery of each wire passing disc 2. During electroplating, the steel wire is wound in the wire passing grooves 3. As Figures 10 - 11 shown, the wire passing groove 3 includes an inner groove 4 and an outer groove 5 that are communicated with each other. As Figure 5 shown, on the end face of the wire passing disc 2, a cathode hole 6, a limiting hole 7 and a mounting hole 8 are sequentially formed from outside to inside. The cathode holes 6 and the limiting holes 7 are both provided in a plurality and are evenly arranged along the circumferential direction of the wire passing disc 2. The mounting hole 8 is coaxially arranged with the wire passing disc 2. Annular grooves 9 are coaxially formed on the end faces of both ends of the wire passing disc 2. Through holes 10 and connection holes 11 are sequentially formed on the inner side surface of the annular groove 9 from inside to outside. The through holes 10 and the connection holes 11 are both provided in a plurality around the mounting hole 8. By providing a plurality of through holes 10, the weight of the cathode roller is effectively reduced, the material usage is reduced, and the cost is reduced. The bolt 15 passes through the corresponding connection holes 11 on two adjacent wire passing discs 2 and is threadedly connected with a nut. The fixed connection between a group of wire passing discs 2 is realized through the bolt 15. A transmission shaft 12 is arranged in the mounting hole 8. The transmission shaft 12 is fixedly connected with the cover body 1. One end of the transmission shaft 12 penetrates through the cover body 1 and is connected to a power device. The power device is used to drive the transmission shaft 12 to rotate. Both ends of the transmission shaft 12 penetrate through the corresponding cover bodies 1 and are rotatably arranged on corresponding bearing seats through bearings. One end of the transmission shaft 12 is fixedly connected with a power device. The power device is a motor, which drives the transmission shaft 12 to drive the cover body 1 to rotate, and further drives a plurality of wire passing discs 2 between the two cover bodies 1 to rotate.
[0032] Conductive rods 13 are arranged in the cathode holes 6. The conductive rods 13 sequentially penetrate through a plurality of inner grooves 4. The cross section of the inner groove 4 is triangular, and the cross section of the outer groove 5 is rectangular. The steel wire is wound in the wire passing groove 3 and contacts the conductive rod 13, thereby ensuring the smooth progress of electroplating. At the same time, when the steel wire swings during electroplating, since the steel wire swings along the axial direction of the wire passing disc 2, that is, the swinging direction of the steel wire is the axial direction of the conductive rod, it will not be separated from the conductive rod 13 due to swinging, ensuring the smooth progress of the electroplating process and ensuring the electroplating effect.
[0033] A limiting rod 14 is inserted into the limiting hole 7. Nuts are threadedly connected to both ends of the limiting rod 14 and the conductive rod 13 after they protrude from the cover body 1. During assembly, the cover body 1 and multiple wire passing discs 2 are both sleeved on the transmission shaft 12 to ensure that the cover body 1 and the multiple wire passing discs 2 are coaxially corresponding. Subsequently, the circumferential position of the wire passing disc 2 and the cover body 1 is limited by the installation of the limiting rod 14, thereby ensuring the smooth installation of the conductive rod 13. At the same time, the synchronous rotation of the cover body 1 and the multiple wire passing discs 2 is ensured by the multiple limiting rods 14 and the multiple conductive rods 13.
[0034] The middle part of the conductive rod 13 is a smooth rod, and threads are provided at both ends to ensure the contact between the smooth part in the middle of the conductive rod 13 and the steel wire, and reduce the friction between the conductive rod 13 and the steel wire. The middle part of the limiting rod 14 is a smooth rod, and threads are provided at both ends. Since the middle parts of the limiting rod 14 and the conductive rod 13 are both smooth surfaces, during installation. Just insert the limiting rod 14 and the conductive rod 13 into the corresponding limiting hole 7 and the cathode hole 6 respectively. Subsequently, tighten the corresponding nuts at both ends of the conductive rod 13 and the limiting rod 14 respectively, so that the cover body 1 and the multiple wire passing discs 2 are axially fixed, and the disassembly and assembly are convenient.
[0035] During use, since the conductive rod 13 penetrates through multiple inner grooves 5, the steel wire wound in the wire passing groove 3 contacts the conductive rod 13, ensuring the smooth progress of electroplating. During the electroplating process, when the steel wire swings, due to the limitation of the two side walls of the outer groove 4, the steel wire always keeps in contact with the conductive rod 13 exposed in the inner groove 5, ensuring the smooth progress of the electroplating process and ensuring the electroplating effect and efficiency.
[0036] The above embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent should be included in the scope of the present invention's patent application.
