Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of diamond wire production equipment, and in particular to an adaptive control mechanism for diamond wire drawing tension. Background Technology
[0002] Diamond wire, as an important cutting tool, is widely used in industries such as photovoltaics and semiconductors to cut hard and brittle materials such as silicon wafers and sapphire. In the production process of diamond wire, the drawing process is a key step, and its tension stability directly affects the uniformity, tensile strength and surface quality of the wire. If the tension is not properly controlled, it may lead to problems such as wire breakage, wire diameter fluctuation and coating peeling, which in turn affects the cutting efficiency and yield.
[0003] Currently, tension control in the diamond wire drawing process mainly adopts traditional mechanical tension control or electrical control methods. However, these methods cannot be adjusted in real time according to the actual situation during the drawing process. When the drawing speed changes, the wire diameter fluctuates, or other interference factors are encountered, the tension will fluctuate significantly, resulting in uneven wire diameter and reduced surface quality of the diamond wire. To address this, we have provided an adaptive tension control mechanism for diamond wire drawing. Utility Model Content
[0004] This utility model provides a diamond wire drawing tension adaptive control mechanism to solve the technical problems existing in the background art.
[0005] The purpose and effect of this utility model diamond wire drawing tension adaptive control mechanism are achieved by the following specific technical means: the diamond wire drawing tension adaptive control mechanism includes a mounting plate and a set of supporting wheels disposed on the front of the mounting plate, a tension adaptive component is disposed between the set of supporting wheels, the tension adaptive component includes a hanging plate disposed on the front of the mounting plate, a U-shaped plate is disposed below the hanging plate, and a tension adjusting wheel is rotatably connected to the inner wall of the U-shaped plate.
[0006] The tension adaptive component also includes an adaptive structure disposed between the hanging plate and the U-shaped plate for automatically adjusting the tension of the diamond wire by the tension adjusting wheel, and an adjustment structure disposed on the hanging plate for adjusting the range of tension applied to the diamond wire by the tension adjusting wheel.
[0007] Preferably, the adaptive structure of the tension adaptive component includes a set of sliding columns slidably connected to the upper surface of the hanging plate, the bottom end of each sliding column being connected to the upper surface of the U-shaped plate, and a spring being sleeved on the outside of each sliding column.
[0008] Preferably, the top ends of the two sliding columns are fixedly connected to a limiting plate.
[0009] Preferably, the U-shaped plate has stabilizing grooves on both its left and right sides, and each stabilizing groove has an L-shaped stabilizing plate slidably connected to its inner wall. The top of each L-shaped stabilizing plate is connected to the bottom surface of the hanging plate.
[0010] Preferably, the adjustment structure of the tension adaptive component includes a threaded column threaded to the hanging plate, a support block rotatably connected to the bottom end of the threaded column, and the rear end of the support block being connected to the front of the mounting plate.
[0011] Preferably, a hexagonal cap is fixedly connected to the top of the threaded post.
[0012] Preferably, a set of guide plates are slidably connected to the hanging plate, and the back of the guide plates is connected to the front of the mounting plate.
[0013] Preferably, the tension adjusting wheel is made of ceramic material.
[0014] Beneficial effects:
[0015] 1. By setting the tension adaptive component, the tension of the diamond wire can be preset, and the tension fluctuation of the diamond wire can be converted into the elastic deformation of the spring. This ensures that the tension is stable within a very small fluctuation range throughout the drawing process, avoiding differences in wire stretching deformation caused by uneven tension. This ensures that the diamond wire is subjected to uniform force during the drawing process, and ultimately achieves the consistency of wire diameter and the stability of surface quality.
[0016] 2. By using the stabilizing groove and the L-shaped stabilizing plate, the connection between the U-shaped plate and the hanging plate can be made, ensuring the stability of the U-shaped plate and effectively preventing the U-shaped plate from shaking under the tension of the diamond wire, ensuring that the tension adjusting wheel is always kept in the predetermined position.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] As attached Figure 1 To be continued Figure 4 As shown: The diamond wire drawing tension adaptive control mechanism includes a mounting plate 1 and a set of supporting wheels 2 disposed on the front of the mounting plate 1. A tension adaptive component 3 is disposed between the set of supporting wheels 2. The tension adaptive component 3 includes a hanging plate 301 disposed on the front of the mounting plate 1. A U-shaped plate 302 is disposed below the hanging plate 301. A tension adjusting wheel 303 is rotatably connected to the inner wall of the U-shaped plate 302. The tension adjusting wheel 303 is made of ceramic material, which can effectively prevent wear, breakage and surface scratches of the diamond wire during high-speed drawing. At the same time, the ceramic material has good chemical stability and can resist the corrosion of chemical media such as coolant and lubricant during diamond wire production, avoiding surface roughness or particle shedding caused by material corrosion, thereby preventing dents or impurities from adhering to the diamond wire surface. In addition, the ceramic tension adjusting wheel 303 is lightweight and has a low coefficient of thermal expansion. It is not easily deformed by temperature changes during long-term continuous operation, ensuring its contact accuracy with the diamond wire and maintaining a stable tension adjustment effect, effectively improving the surface quality and production efficiency of the diamond wire.
[0025] As attached Figure 2 As shown: stabilizing grooves 307 are provided on both the left and right sides of the U-shaped plate 302. An L-shaped stabilizing plate 308 is slidably connected to the inner wall of each stabilizing groove 307. The top of each L-shaped stabilizing plate 308 is connected to the bottom surface of the hanging plate 301. By utilizing the cooperation of the stabilizing grooves 307 and the L-shaped stabilizing plates 308, the U-shaped plate 302 and the tension adjusting wheel 303 can be reinforced and stabilized, ensuring that the tension adjusting wheel 303 always remains in the predetermined position, avoiding tension fluctuations caused by shaking and deviation, thereby providing a stable and reliable tension control guarantee for diamond wire pulling operations.
[0026] As attached Figure 3 With appendix Figure 4As shown: The tension adaptive component 3 also includes an adaptive structure disposed between the hanging plate 301 and the U-shaped plate 302 for automatically adjusting the tension of the diamond wire by the tension adjusting wheel 303. The adaptive structure of the tension adaptive component 3 includes a set of sliding columns 304 slidably connected to the upper surface of the hanging plate 301. The bottom end of each sliding column 304 is connected to the upper surface of the U-shaped plate 302. A spring 305 is sleeved on the outside of each sliding column 304. When the tension of the diamond wire acts on the tension adjusting wheel 303, the U-shaped plate 302 will convert the tension of the diamond wire into a vertically upward holding force. The U-shaped plate 302 compresses the spring 305. When the tension of the diamond wire fluctuates, the spring 305, with its elastic properties, can dynamically adjust its extension and retraction in real time to follow the tension changes. It also transmits the holding force to the diamond wire through the tension adjusting wheel 303, so that the tension of the diamond wire remains stable, effectively buffering sudden tension changes and avoiding large fluctuations. The tops of the two sliding columns 304 are fixedly connected to the limiting plate 306. The limiting plate 306 can prevent the sliding columns 304 from detaching from the hanging plate 301, thereby maintaining a stable connection between the U-shaped plate 302 and the hanging plate 301.
[0027] As attached Figure 2 With appendix Figure 4 As shown: An adjustment structure is set on the hanging plate 301 to adjust the tension range applied to the diamond wire by the tension adjusting wheel 303. The adjustment structure of the tension adaptive component 3 includes a threaded post 309 threadedly connected to the hanging plate 301. The bottom end of the threaded post 309 is rotatably connected to a support block 310. The rear end of the support block 310 is connected to the front of the mounting plate 1. By rotating the threaded post 309, the vertical height of the hanging plate 301 can be precisely adjusted, thereby driving the tension adjusting wheel 303 to rise and fall synchronously, so as to apply different degrees of holding force to the diamond wire and make the diamond wire produce corresponding tension changes. The top end of the threaded post 309 is fixedly connected to a hexagonal cap 311. The hexagonal cap 311 makes it convenient for the operator to rotate the threaded post 309 with tools. A set of guide plates 312 is slidably connected to the hanging plate 301. The back of the guide plate 312 is connected to the front of the mounting plate 1. The guide plate 312 can guide the hanging plate 301 to ensure that the hanging plate 301 maintains a stable state of rising and falling.
[0028] Working principle: During the diamond wire drawing operation, the diamond wire passes sequentially over the two support rollers 2 and under the tension adjusting roller 303 between them. By rotating the threaded column 309, the vertical height of the hanging plate 301 can be precisely adjusted, thereby driving the tension adjusting roller 303 to rise and fall synchronously. This allows different levels of holding force to be applied to the diamond wire, causing corresponding tension changes. When the tension of the diamond wire acts on the tension adjusting roller 303, the U-shaped plate 302 converts the tension into a vertically upward holding force. The U-shaped plate 302 then compresses the spring 305. When the tension of the diamond wire fluctuates, the spring 305, due to its elastic properties, can dynamically adjust its extension and contraction in real time to follow the tension changes. It also transmits the holding force to the diamond wire through the tension adjusting roller 303, keeping the diamond wire tension stable, effectively buffering sudden tension changes, avoiding large fluctuations, and ensuring uniform force on the diamond wire during the drawing process. Ultimately, this achieves consistency in wire diameter and stability in surface quality.
