Description

Technical Field

[0001] This utility model relates to the field of steel wire lubrication technology, and in particular to a lubrication device for lifting bar steel wire. Background Technology

[0002] In the process of cutting monocrystalline silicon wafers using diamond wire, after cutting, the crystal rod needs to be lifted off the top of the wire mesh. In the existing technology, the wire jamming during the rod lifting process is consistently too high, reaching 5%. This cannot completely avoid the waste of steel wire caused by wire jamming and breakage, as well as the scratches on the silicon wafer surface caused by the steel wire. This also leads to screen breakage during the cell-side screen printing process, which seriously affects the waste of steel wire costs, the loss of slicing yield, and the low efficiency caused by screen breakage during the cell-side screen printing process. It also affects the efficiency of a single machine.

[0003] Currently, traditional cutting machines suffer from uneven lubrication film thickness on the surface of diamond wire and a certain amount of residual silicon powder, leading to local lubrication failure on the diamond wire surface, large fluctuations in the coefficient of friction, and consequently, a certain probability of wire breakage, thus reducing cutting efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a lubrication device for lifting steel wire, which solves the problems mentioned in the background art, such as uneven thickness of the lubricating film on the surface of diamond wire and a certain amount of residual silicon powder on the surface, which leads to local lubrication failure on the surface of diamond wire, large fluctuation of the friction coefficient, and thus a certain probability of wire breakage, reducing cutting efficiency.

The swinging mechanism includes a servo motor B threadedly connected to one side of the cutting box. An eccentric wheel A is fixedly connected to the output end of the servo motor B. A metal plate is fixedly connected to one side of the eccentric wheel A. The metal plate has a cavity inside, with a micro-slit at the bottom of the cavity. The eccentric wheel B is located on one side of the metal plate.

[0008] As a further embodiment of this utility model, the connecting rod is fixedly connected to the inner wall of the cutting box, and a guide wheel is rotatably connected to one side of the connecting rod. An annular groove is formed on the surface of the guide wheel, and the guide wheel is located directly below the oil bottle. The annular groove serves to constrain the movement of the diamond wire.

[0009] As a further embodiment of this utility model, the inner wall of the cutting box is rotatably connected with three sets of rollers, one of which is located on one side of the brush. The setting of the rollers drives the diamond wire to rotate, thereby realizing the cutting function.

[0010] As a further embodiment of this utility model, the servo motor B is connected through to one side of the cutting box, and the eccentric wheel B has the same structure as the eccentric wheel A. The eccentric wheel B is rotatably connected to the inner wall of the cutting box. Through the setting of the servo motor B, it plays the role of driving the metal plate to reciprocate.

[0014] (III) Beneficial Effects

[0015] This utility model provides a lubrication device for lifting bar steel wire, which has the following beneficial effects:

[0016] 1. This lifting rod steel wire lubrication device, through the setting of connecting rod, guide wheel, oil dripping mechanism and swinging mechanism, allows the diamond wire to first pass through the guide wheel into the cutting area when the multi-wire cutting machine is working. The oil bottle drips down by gravity to initially lubricate the diamond wire at the annular groove of the guide wheel. At the same time, servo motor B is started. Servo motor B drives the eccentric wheel, which drives the metal plate with micron-level slits at the bottom to swing back and forth at 10-15°. Under the action of centrifugal force, the lubricating oil in the cavity is evenly thrown out from the slits to form a dynamic oil curtain that vertically covers the diamond wire. Thus, the thickness of the lubricating film on the surface of the diamond wire is increased by the dripping of lubricating oil and the swinging oil curtain, which simultaneously reduces the vibration of the wire and the friction during cutting, reduces the breakage rate of the diamond wire, and improves the yield of silicon wafer cutting.

[0017] 2. This lifting bar steel wire lubrication device, through the setting of rollers and cleaning mechanism, when the multi-wire cutting machine is working, the servo motor A drives the rotating shaft to rotate the brush at a certain speed. After the cutting fluid is sprayed by the atomizing nozzle, the brush forms a reverse contact with the running diamond wire. The nylon filaments of the rotating brush scrape off the residual silicon powder on the surface of the diamond wire at a 45° cutting angle. At the same time, the cutting fluid forms a uniform oil film with a thickness of 5-8μm under mechanical action, realizing the dual function of "scraping-lubrication" in a single action. Thus, through the design of the cleaning mechanism, the surface friction coefficient of the diamond wire is reduced by 30%, the wire temperature is reduced, and the wire breakage problem caused by the accumulation of impurities is effectively avoided.

[0027] Servo motor B501 is connected through to one side of cutting box 1. Eccentric wheel B505 has the same structure as eccentric wheel A502. Eccentric wheel B505 is rotatably connected to the inner wall of cutting box 1. Through the setting of servo motor B501, it plays the role of driving metal plate 503 to reciprocate.

[0028] The top of the metal plate 503 is connected to an oil inlet pipe 9, and an oil tank 10 is connected to one side of the oil inlet pipe 9. The oil inlet pipe 9 is used to transport lubricating oil.

At the same time, the cutting fluid forms a uniform oil film with a thickness of 5-8μm under mechanical action, realizing the dual function of "scraping-lubrication" in a single action.
