Description

Technical Field

[0001] This application belongs to the technical field of tungsten wire pretreatment equipment, and specifically relates to a grinding machine used in the pretreatment of tungsten wire and diamond wire. Background Technology

[0002] The most widely used process at present is the electroplating of carbon steel wire with diamond wire. By consolidating diamond micro powder onto carbon steel wire, the coating has good consolidation ability of diamond and excellent substrate bonding ability, ensuring that the carbon steel wire with diamond wire coating has good cutting ability during silicon wafer wire cutting.

[0003] The manufacturing process of electroplated carbon steel wire and diamond wire includes pretreatment, pre-plating, abrasive coating, thickening, and post-treatment. Pre-plating involves immersing the steel wire substrate, after the first process, into a pre-plating bath, where a thin layer of nickel metal is electrodeposited onto the wire. Because the steel wire substrate and the nickel coating can form metallic bonds and mechanical interlocking forces, the bonding strength between the carbon steel wire and the nickel coating is excellent. On the one hand, this prevents damage to the mechanical properties of the steel wire substrate and avoids hydrogen embrittlement; on the other hand, the composite coating and the base coating bond to the substrate through the nickel metal matrix, making the subsequent diamond abrasive grains bond more firmly to the steel wire substrate. Therefore, cleaning the tungsten wire before pre-plating is a crucial step.

[0004] A technical solution disclosed in CN220783239U, a tungsten wire surface polishing and grinding device, involves setting a limiting block and a screw. Rotating the handle causes the screw to rotate, causing it to slide to one side and simultaneously sliding the limiting block, which in turn drives the rotating shaft to slide. Since multiple grinding wheels are symmetrically arranged, their synchronous sliding occurs as the screw rotates. However, the inventors believe this tungsten wire polishing method is inefficient, and applying pressure only to one side of the horizontal plane can easily cause the tungsten wire to break. Furthermore, this structure cannot be applied to polishing extremely fine tungsten wires. Utility Model Content

[0005] The purpose of this invention is to address the existing problems of existing grinding machines being unable to grind extremely fine tungsten wires, having low grinding efficiency, and being prone to tungsten wire breakage. This invention provides a grinding machine that sets grinding mechanisms on both sides of the tungsten wire in a vertical plane, and sets multiple grinding mechanisms on the tungsten wire conveying line, and can arrange multiple tungsten wires side by side in the grinding mechanism for simultaneous grinding.

[0006] To achieve the above technical objectives, the following technical solution is provided: a grinding machine used in the pretreatment of tungsten wire diamond wire, including a main support, the main support having a conveying support part and a power support part, a chain conveying mechanism being provided on the conveying support part, the chain conveying mechanism including a pair of conveying chains, a plurality of grinding plates being fixed between the conveying chains, and the movement direction of the conveying chains being opposite to the conveying direction of the tungsten wire diamond wire.

[0007] The roller polishing group is also provided, and the rotating directions of the polishing rollers in the roller polishing group are opposite to the conveying direction of the tungsten wire diamond wire, and the outer surfaces of the polishing rollers are in close contact with the upper surface of the polishing plate to form a polishing area of the diamond wire.

[0008] In an implementable manner, the chain conveying mechanism further comprises a pair of conveying shafts, the conveying shafts are arranged at both ends of the conveying support part and are located on the conveying path of the tungsten wire diamond wire, and a pair of sprockets are arranged on the conveying shafts and are matched with a pair of conveying chains.

[0009] The conveying support group has a pair of support frames, each support frame is fixed with each conveying shaft.

[0010] The chain drive motor is connected with one of the conveying shafts through the sprocket group, and the chain drive motor is located on the power support part.

[0011] In an implementable manner, the chain conveying mechanism further comprises a pair of support edges, the conveying chains are arranged above the support edges, and the support edges are fixed through the support rods arranged on the conveying support part.

[0012] In an implementable manner, the roller polishing group comprises at least one single polishing roller,

[0013] The single polishing roller has a first drive motor and a first transmission system, the first drive motor is located on the power support part, and the first transmission system realizes the connection of the first drive motor and the polishing roller through the belt pulley group.

[0014] In an implementable manner, the roller polishing group further comprises at least one double polishing roller,

[0015] The double polishing roller has a second drive motor and a second transmission system, the second drive motor is located on the power support part, the second transmission system realizes the connection of the second drive motor and one polishing roller through the belt pulley group, and the other polishing roller is connected with the first polishing roller through the belt transmission.

[0016] In an implementable manner, each polishing roller is arranged in a polishing unit, the polishing unit further comprises a polishing support for fixing the rotating shafts at both ends of the polishing roller, the polishing support is arranged on the conveying support part and is located on both sides of the chain conveying mechanism.

[0017] In an implementable manner, the polishing unit is also provided with an adjusting part at the fixing position of the end of each rotating shaft and the polishing support, and the adjusting part controls the distance of the polishing area.

[0018] In an implementable manner, the polishing unit is arranged to be inclined, that is, at an angle to the conveying direction of the tungsten wire diamond wire.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The grinding mechanism arranged on the upper and lower sides of the tungsten wire can make the tungsten wire grinding more uniform, and the tungsten wire will not break due to unilateral stress, especially the grinding of the extremely thin tungsten wire in the technical scheme. In the technical scheme, the chain conveying grinding group is adopted in the bottom grinding mechanism so that the tungsten wire can be in a continuous grinding state during the conveying process, and the tungsten wire has a guiding and positioning effect, preventing the tungsten wire from deviating under the action of the roller grinding group. The combination of single and double roller grinding groups ensures that the motor is installed on the power support part with sufficient position, and the rotating speed of each grinding roller can be adjusted to realize the uniform grinding of the tungsten wire in all directions. The inclination of each grinding roller is arranged to realize the actual friction force on the tungsten wire. BRIEF DESCRIPTION OF DRAWINGS
