Description

Technical Field

[0001] The invention relates to a cathode roller. Background Art

[0002] Copper electroplating is a mature process of plating copper on metal surfaces through the principle of electrolysis. It mainly applies positive and negative charges in the electroplating solution to allow copper ions to gather on the metal surface, thereby achieving the purpose of electroplating. The cathode roller is an important device in copper electroplating.

[0003] Diamond wire is a cutting tool made of electroplated metal as a binder. Through the electrocrystallization effect of the electroplated metal, the high-hardness and high-wear-resistant diamond abrasive is firmly fixed on the steel wire matrix so that the steel wire has diamond micro-teeth. During the sanding process of the diamond wire, the cathode roller plays a conductive role. During the sanding, the diamond wire will be wound in the groove of the cathode roller, so that the diamond wire will be directly connected to the cathode plate and the mother plate on the cathode roller. After a long sanding process, the cathode plate and the mother plate in the cathode roller will be damaged. If the cathode plate or the mother plate is damaged, the entire cathode plate and the mother plate need to be replaced. The production cost is high after long-term use, and the replacement is also inconvenient, which cannot meet the actual use needs. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cathode roller with a simple structure, which only needs to replace the long bolts after long-term use without replacing the entire cathode roller of the negative sheet or the mother sheet.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a cathode roller, including a cathode plate, a locking screw, a cover plate, a mother plate, a long bolt and a cathode roller shaft; the upper end of the cathode plate is connected to the cover plate through a plurality of locking screws; the mother plate is located at the lower end of the cathode plate, and the cathode plate and the mother plate are provided with the same plurality of parallel grooves; a plurality of the long bolts pass through the cathode plate and the mother plate in turn to fasten the two together, and a part of the long bolts is arranged in the groove; the long bolts are made of stainless steel; the cathode roller shaft is arranged in the cathode plate and the mother plate through bearings.

[0006] Preferably, the cover plate is made of stainless steel.

[0007] Preferably, the number of the locking screws is four.

[0008] Preferably, the interval between each groove is 10 mm, the width of each groove is 5 mm, and the arc of the groove is 45°.

[0009] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0010] The cathode roller of the scheme of the present invention has a simple and practical overall structure. After the diamond wire is sanded for a long time, only the corroded long bolts need to be replaced. The production cost is low, the replacement is convenient, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 It is a structural schematic diagram of the present invention;

[0012] Attached Figure 2 For attachment Figure 1 A top view of

[0013] Among them: 1. cathode plate; 2. locking screw; 3. cover plate; 4. mother plate; 5. long bolt; 6. groove; 7. cathode roller. DETAILED DESCRIPTION

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] As attached Figure 1-2 A cathode roller shown in the figure comprises a cathode sheet 1, a locking screw 2, a cover plate 3, a mother sheet 4, a long bolt 5 and a cathode roller shaft 7; the upper end of the cathode sheet 1 is connected to the cover plate 3 via a plurality of locking screws 2; the mother sheet 4 is located at the lower end of the cathode sheet 1, and the cathode sheet 1 and the mother sheet 5 are provided with a plurality of identical parallel grooves 6; a plurality of the long bolts 5 sequentially pass through the cathode sheet 1 and the mother sheet 5 to fasten the two together, and a portion of the long bolts 5 is arranged in the groove 6; the long bolts 5 are made of stainless steel; the cathode roller 7 is arranged in the cathode sheet 1 and the mother sheet 4 via a bearing.

[0016] The cover plate 3 is made of stainless steel; the number of the locking screws 2 is four; the interval between the grooves 6 is 10 mm, the width of each groove 6 is 5 mm, and the curvature of the groove 6 is 45°.

[0017] During the sanding process of the diamond wire, the diamond wire will be entangled on the long bolt located in the groove. After a long period of sanding, the long bolt will be damaged and corroded. At this time, you only need to take out the long bolt for replacement. The existing technology will directly damage and corrode the negative plate and the mother plate. Compared with the two, directly replacing the long bolt not only has a low production cost, but also is easy to replace, has strong practicality, and meets the actual use needs.

[0018] Among them, the long bolts are made of stainless steel to ensure their service life.

[0019] Furthermore, the width and angle of the groove are determined according to the actual diameter of the diamond wire.

[0020] The cathode roller of the present invention has a simple and practical overall structure. After the diamond wire is sanded for a long time, only the corroded long bolts need to be replaced. The production cost is low, the replacement is convenient, and the roller has strong practicality.

[0021] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
