Description

Technical Field

[0001] This utility model relates to the technical field of diamond wire cutting equipment, specifically a wire swing and tension adjustment device. Background Technology

[0002] Diamond wire cutting (DFD) technology, as a highly efficient and precise machining method, has been widely used in the cutting of hard and brittle materials such as photovoltaics, semiconductors, sapphire, and magnetic materials. In this technology, the diamond wire loop reciprocates at high speed, a key process that avoids localized wear of the loop, promotes chip removal, and improves cutting efficiency and cross-sectional quality.

[0003] Currently, in existing technologies, the swaying drive function and tension control function of the loop are mostly implemented by two independent systems. The swaying drive system usually consists of a servo motor and a lead screw mechanism to drive a slide with guide wheels to perform reciprocating linear motion. The tension control system, on the other hand, requires an additional independent tensioning mechanism, such as a pneumatic tensioning cylinder, a counterweight, or a tension arm driven by another motor. When the swaying of the line causes changes in the loop path, the response of the independent tensioning mechanism is delayed, which can easily cause tension fluctuations. This not only affects the cutting accuracy but may also cause the loop to break due to excessive tension. Utility Model Content

[0004] To address the shortcomings of existing technologies where the response of the independent tensioning mechanism lags when the loop path changes due to line swaying, easily causing tension fluctuations that not only affect cutting accuracy but may also lead to loop breakage due to excessive tension, this utility model provides a line swaying and tension adjustment device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a line swing and tension adjustment device, including a first bracket and a second bracket. The first bracket is provided with a first drive plate that can slide along its length direction. The first drive plate is provided with a driving wheel and a swing driven wheel. The first bracket is provided with a first driving member for driving the first drive plate to move. The second bracket is provided with a second drive plate and a third drive plate that can slide independently along its length. Both the second drive plate and the third drive plate are provided with tension driven wheels. The drive wheel, the oscillating driven wheel and the tension driven wheel are surrounded by diamond-cut rings. The second bracket is provided with a second driving member for driving the second driving plate to move and a third driving member for driving the third driving plate to move.

[0006] As a preferred technical solution of this utility model, the first driving component includes a first motor fixedly connected to the outer wall of the first bracket, a first lead screw fixedly connected to the output end of the first motor, and a first threaded sleeve threadedly connected to the first lead screw fixedly connected to the outer wall of the first driving plate on the side near the first lead screw.

[0007] As a preferred technical solution of this utility model, a first slide rail is fixedly connected to the side of the outer wall of the first bracket near the first lead screw, and a first slider is fixedly connected to the side of the outer wall of the first drive plate near the first slide rail. The first drive plate is slidably connected to the first bracket through the first slide rail and the first slider.

[0008] As a preferred technical solution of this utility model, the second driving component includes a second motor fixedly connected to the top of one side of the outer wall of the second bracket, a second lead screw fixedly connected to the output end of the second motor, and a second threaded sleeve threadedly connected to the second lead screw fixedly connected to the side of the outer wall of the second driving plate near the second lead screw.

[0009] As a preferred technical solution of this utility model, the third driving component includes a third motor fixedly connected to the bottom end of one side of the outer wall of the second bracket, a third lead screw coaxially arranged with the second lead screw fixedly connected to the output end of the third motor, and a third threaded sleeve threadedly connected to the third lead screw fixedly connected to one side of the outer wall of the third driving plate.

[0010] As a preferred technical solution of this utility model, a second slide rail is fixedly connected to one side of the outer wall of the second bracket, which is arranged along the length direction of the second bracket. A second slider is fixedly connected to the second slide rail on the side of the second drive plate near the second slide rail. The second drive plate is slidably connected to the second bracket through the second slide rail and the second slider. The third drive plate is fixedly connected to the side of the second slide rail with a third slider that is slidably connected to the second slide rail. The third drive plate is slidably connected to the second bracket through the second slide rail and the third slider.

[0011] As a preferred embodiment of this utility model, a cutting motor for driving the rotation of the drive wheel is fixedly connected to the outer side wall of the first drive plate near the drive wheel.

[0012] In summary, this application has the following beneficial effects: This application utilizes the cooperation of a first bracket, a second bracket, a first drive plate, a drive wheel, a oscillating driven wheel, a first drive component, a second drive plate, a third drive plate, a tension driven wheel, a diamond cutting loop, and a second and third drive component. During use, the first drive component drives the first drive plate and its drive wheel and oscillating driven wheel to reciprocate linearly, achieving the oscillation function of the loop. This causes the cutting angle of the loop to continuously change in the cutting section, improving cutting efficiency while minimizing the formation of cutting marks. The device can simultaneously control the second and third drive components to independently drive the second and third drive plates while the first drive component moves the first drive plate. By changing the distance between the two tension driven wheels, the total length of the quadrilateral closed-loop path is actively adjusted, thereby dynamically balancing and stabilizing the tension of the diamond cutting loop. This minimizes the impact of tension fluctuations on the cutting effect and allows the cutting line to be cut at an inclined angle to adapt to different cutting scenarios.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Please refer to Figure 1 , Figure 2 and Figure 3 This utility model discloses a wire swing and tension adjustment device, including a first support 1 and a second support 2. The first support 1 is provided with a first drive plate 3 that can slide along its length direction. The first drive plate 3 is provided with a driving wheel 4 and a swing driven wheel 5. A cutting motor 18 for driving the driving wheel 4 to rotate is fixedly connected to the side of the outer wall of the first drive plate 3 near the driving wheel 4. The first support 1 is provided with a first drive member 6 for driving the first drive plate 3 to move. The first drive member 6 includes a first motor 61 fixedly connected to the outer wall of the first support 1. A first lead screw 62 is fixedly connected to the output end of the first motor 61. A first threaded sleeve 63 threadedly connected to the first lead screw 62 is fixedly connected to the side of the outer wall of the first drive plate 3 near the first lead screw 62. A first slide rail 13 is fixedly connected to the side of the outer wall of the first bracket 1 near the first lead screw 62, and a first slider 14 is fixedly connected to the side of the outer wall of the first drive plate 3 near the first slide rail 13. The first drive plate 3 is slidably connected to the first slide rail 13. The first drive plate 3 is slidably connected to the first bracket 1 through the first slide rail 13 and the first slider 14. After the first motor 61 is turned on, the first motor 61 can drive the first lead screw 62 to rotate, thereby driving the first threaded sleeve 63 and the first drive plate 3 to move along the first lead screw 62 (during this process, the first slider 14 slides along the first slide rail 13, thereby limiting the first threaded sleeve 63 and the first drive plate 3, ensuring that the first drive plate 3 and the first threaded sleeve 63 move linearly along the first lead screw 62).

[0017] Reference Figure 2 and Figure 3 The second support 2 is provided with a second drive plate 7 and a third drive plate 8 that can slide independently along its length. A second slide rail 15 is fixedly connected to one side of the outer wall of the second support 2 along the length of the second support 2. A second slider 16 is fixedly connected to the second slide rail 15 on the side of the second drive plate 7 near the second slide rail 15. The second drive plate 7 is slidably connected to the second support 2 through the second slide rail 15 and the second slider 16. A third slider 17 is fixedly connected to the second slide rail 15 on the side of the third drive plate 8 near the second slide rail 15. The third drive plate 8 is slidably connected to the second support 2 through the second slide rail 15 and the third slider 17. Both the second drive plate 7 and the third drive plate 8 are equipped with tension driven wheels 9. The drive wheel 4, the oscillating driven wheel 5, and the tension driven wheel 9 are all surrounded by a diamond cutting ring 10. In use, the cutting motor 18 can be started to drive the drive wheel 4 to rotate, which in turn drives the diamond cutting ring 10 surrounded by the drive wheel 4, the oscillating driven wheel 5, and the tension driven wheel 9 to rotate cyclically. The diamond particles on the diamond cutting ring 10 cut the material in contact with it.

[0018] Reference Figure 1 , Figure 2 and Figure 3 The second bracket 2 is provided with a second driving component 11 for driving the second driving plate 7 to move and a third driving component 12 for driving the third driving plate 8 to move. The second driving component 11 includes a second motor 111 fixedly connected to the top of one side of the outer wall of the second bracket 2. The output end of the second motor 111 is fixedly connected to a second lead screw 112. A second threaded sleeve 113 is fixedly connected to the second lead screw 112 on the side of the outer wall of the second driving plate 7 near the second lead screw 112. After the second motor 111 is turned on, the second motor 111 can drive the second lead screw 112 to rotate, thereby driving the second threaded sleeve 113 and the second drive plate 7 to move along the second lead screw 112 (during this process, the second slider 16 slides along the second slide rail 15, thereby limiting the second threaded sleeve 113 and the second drive plate 7, ensuring that the second drive plate 7 and the second threaded sleeve 113 move linearly along the second lead screw 112). The third driving component 12 includes a third motor 121 fixedly connected to the bottom end of one side of the outer wall of the second bracket 2. The output end of the third motor 121 is fixedly connected to a third lead screw 122 coaxially arranged with the second lead screw 112. A third threaded sleeve 123 threadedly connected to the third lead screw 122 is fixedly connected to one side of the outer wall of the third driving plate 8. After the third motor 121 is turned on, the third motor 121 can drive the third lead screw 122 to rotate, thereby driving the third threaded sleeve 123 and the third drive plate 8 to move along the third lead screw 122 (during this process, the third slider 17 slides along the second slide rail 15, thereby limiting the third threaded sleeve 123 and the third drive plate 8, ensuring that the third drive plate 8 and the third threaded sleeve 123 move linearly along the third lead screw 122).

[0019] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0020] The implementation principle of this utility model is as follows: In use, the diamond cutting loop 10 is first passed around the driving wheel 4, the tension driven wheel 9 on the second drive plate 7, the tension driven wheel 9 on the third drive plate 8 and the oscillating driven wheel 5 to form a closed loop. Then, the second motor 111 and the third motor 121 are started to drive the second lead screw 112 and the third lead screw 122 to rotate, so that the second drive plate 7 moves upward along the second lead screw 112, and at the same time the third drive plate 8 moves downward along the third lead screw 122 until the diamond cutting loop 10 is tensioned. Then the second motor 111 and the third motor 121 are turned off to complete the tensioning of the diamond cutting loop 10. Once the diamond cutting ring 10 is tensioned, the cutting motor 18 is started. The cutting motor 18 can drive the drive wheel 4 to rotate at high speed, which in turn drives the diamond cutting ring 10 to rotate in a one-way cycle, and cuts the material through the diamond particles on the surface of the diamond cutting ring 10. During the cutting process, the first motor 61 can be started to drive the first lead screw 62 to rotate, which in turn drives the first threaded sleeve 63 and the first drive plate 3 to perform slow and continuous reciprocating motion (swaying up and down) along the first lead screw 62, thereby making the cutting angle of the loop continuously change in the cutting part, improving the cutting efficiency while minimizing the generation of cutting marks. Simultaneously, when the first motor 61 drives the first lead screw 62 to rotate and further drives the first drive plate 3 to move upward, the second motor 111 and the third motor 121 respectively drive the second lead screw 112 and the third lead screw 122 to rotate, causing the second drive plate 7 to move upward along the second lead screw 112, while the third drive plate 8 moves downward along the third lead screw 122, actively extending the path of the diamond cutting loop 10, thereby maintaining the tension of the diamond cutting loop 10. (When the first drive plate 3 moves upward, the quadrilateral path of the diamond cutting loop 10 tends to shorten, which will lead to a decrease in the tension of the diamond cutting loop 10). When the first motor 61 drives the first lead screw 62 to rotate and further drives the first drive plate 3 to move downward, the second motor 111 and the third motor 121 drive the second lead screw 112 and the third lead screw 122 to rotate respectively, causing the second drive plate 7 to move downward along the second lead screw 112, while the third drive plate 8 moves upward along the third lead screw 122, actively shortening the path of the diamond cutting loop 10, thereby maintaining the tension of the diamond cutting loop 10. (When the first drive plate 3 moves downward, the quadrilateral path of the diamond cutting loop 10 tends to become longer, which will cause the tension of the diamond cutting loop 10 to increase.)
