Description

Technical Field

[0001] This utility model relates to the field of guide wheel cleaning technology, and in particular to a novel guide wheel rinsing device. Background Technology

[0002] The guide wheel is the wheel in a wire cutting machine responsible for winding the wire. It is made of steel internally and coated with a layer of polyurethane externally. It rotates by bearings at both ends and a lead screw passing through the middle. Different specifications have different requirements for the grooving specifications of the guide wheel. The coating and groove shape of the guide wheel have a significant impact on the cutting quality of silicon wafers. Therefore, most manufacturers usually purchase ungrooved guide wheels and perform precision machining on them using CNC grooving machines before putting them into production.

[0003] However, the CNC grooving machine tools currently used in the factory can only perform fine grooving on the guide wheels after the system is programmed. The dirt that is already on the surface of the guide wheels and the debris that sticks to them during grooving cannot be cleaned in time. Simple sweeping or vibration cannot remove the tightly stuck dirt. When such dirty guide wheels are used in wire cutting machines, the high-speed moving diamond wire will be affected by the dirt, resulting in a high defect rate. It will also reduce the cutting quality of silicon wafers and increase the defect rate of large silicon wafers. Utility Model Content

[0044] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] Reference Appendix Figure 1-8This utility model provides a novel guide wheel rinsing device, which includes at least: a support 10, a water distribution pipe 1, a water supply pipe 2, and a rinsing nozzle 3. The water distribution pipe 1 is mounted on the support 10, and its two ends are rotatably connected to the support 10. The water supply pipe 2 and the rinsing nozzle 3 are mounted on the water distribution pipe 1 and are both connected to the interior of the water distribution pipe 1. The water supply pipe 2 supplies water to the water distribution pipe 1 and the rinsing nozzle 3. The rinsing nozzle 3 is located on the side wall of the water distribution pipe 1, and several nozzles are evenly distributed along the axial direction of the water distribution pipe 1. The nozzles are used to spray water onto the guide wheel next to the support 10 and use high-pressure water to clean the dirt that is stuck to the guide wheel.

[0048] In use, the bracket 10 is fixed to one side of the CNC grooving machine tool. The fixing method is not limited; welding, bolt connection, etc. are all acceptable. The water supply pipe 2 is connected to the cooling water tank of the CNC grooving machine tool (the cooling water tank has a built-in water pump). Without much modification to the CNC grooving machine tool, this guide wheel cleaning device can be combined with the CNC grooving machine tool to clean the guide wheel without affecting the grooving process. The water pump built into the cooling water tank can provide high pressure for the water entering the water supply pipe 2, and the water is then sprayed out through the cleaning nozzle 3 to clean the guide wheel. After the guide wheel is cleaned by this device, it can be used in the wire cutting machine to avoid abnormal vibration and friction of the diamond wire, reduce its abnormality rate, improve the cutting effect on silicon wafers, and improve the quality and yield of silicon wafers.

[0049] In addition to the built-in water pump in the cooling water tank, one or more sets of booster pumps 4 can be added between the water supply pipe 2 and the cooling water tank to further increase the water pressure of the flushing nozzle 3 and improve the cleaning effect on the guide wheel. Furthermore, the connection between the flushing nozzle 3, the water distribution pipe 1, or both is equipped with a solenoid valve 5 for controlling the water output. The control program of the solenoid valve 5 can be linked with the grooving process of the CNC grooving machine. During the grooving process, the solenoid valve 5 remains closed, and the flushing nozzle 3 does not spray water. When the grooving process stops, the solenoid valve 5 opens, and the flushing nozzle 3 starts spraying water, thus avoiding mutual interference between the flushing and grooving processes, especially the impact of water spraying on grooving accuracy. Of course, the solenoid valve 5 should also be linked with the booster pump 4. When the solenoid valve 5 opens, the booster pump 4 starts; when the booster pump 4 closes, the solenoid valve 5 closes again, preventing excessive water pressure in the water supply pipe 2 and the water distribution pipe 1, which could cause structural damage and reduce service life.

[0050] In use, the water distribution pipe 1 can be rotated to change the relative angle between the flushing nozzle 3 and the guide wheel according to different needs. However, the water distribution pipe 1 and the water supply pipe 2, which are fully loaded with water, have a large mass. In addition to increasing the frictional resistance at the rotating connection between the water distribution pipe 1 and the bracket 10 to prevent the water distribution pipe 1 from returning to its original position due to its own weight after being rotated to a specified angle, positioning turntables 6 can be set at both ends of the water distribution pipe 1. The positioning turntables 6 are rotatably connected to the bracket 10. Several positioning holes 6-1 are set on the positioning turntables 6 along its circumference, and positioning parts 7 are set on the bracket 10 and pinned to the positioning holes 6-1. By rotating the positioning turntables 6 and connecting the positioning parts 7 to different positioning holes 6-1, the relative angle between the flushing nozzle 3 and the outer guide wheel on the water distribution pipe 1 can be changed. The positioning parts 7 are used for fixing, which can appropriately reduce the frictional resistance between the positioning turntables 6, the water distribution pipe 1 and the bracket 10, improve the operating efficiency when rotating the water distribution pipe 1 and save labor. Of course, the positioning turntable 6 can be used directly as the rotating shaft of the water distribution pipe 1, or a thinner rotating shaft can be set on the side of the positioning turntable 6 away from the water distribution pipe 1 to further reduce the rotation resistance. Whether the positioning turntable 6 is used directly as the rotating shaft or an additional rotating shaft is added, the rotation installation method on the bracket 10 is the existing technology, such as installation through bearings, which will not be elaborated here.

[0051] Reference Appendix Figure 3 In this embodiment, the positioning component 7 is configured as follows: a pin 7-1, a return spring 7-2, and a connecting plate 7-3. The return spring 7-2 is distributed around the outer periphery of the pin 7-1 and extends in the same direction as the pin 7-1. The ends of both the pin 7-1 and the pin 7-2 that are away from the positioning turntable 6 are connected to the connecting plate 7-3. The connecting plate 7-3 is engaged with the bracket 10. When the connecting plate 7-3 is moved in the direction away from the positioning turntable 6, the pin 7-1 and the return spring 7-2 move and stretch with the connecting plate 7-3, respectively. When the pin 7-1 is disengaged from the positioning hole 6-1, the positioning turntable 6 and the water distribution pipe 1 are in a rotatable state. After releasing the pin 7-1, under the action of the return spring 7-2, the pin 7-1 moves toward the positioning turntable 6 and is then inserted into the positioning hole 6-1. Since the connecting plate 7-3 is restricted by the bracket 10 and cannot move, the pin 7-1 cannot move, and the positioning turntable 6 and the water distribution pipe 1 cannot rotate.

[0052] However, the configuration of positioning component 7 is not limited to the attached figure. Figure 3 As shown, the positioning component 7 can be positioned on the side of the bracket 10 away from the water distribution pipe 1, or it can be positioned on the side close to the water distribution pipe 1, but the latter is slightly less convenient to operate than the former; the pin 7-1 can be positioned as shown in the attached figure. Figure 3As shown, the pin 7-1 can be connected to the positioning hole 6-1 on the positioning turntable 6 after penetrating the bracket 10. Alternatively, there may be no direct penetrating or connecting relationship between the pin 7-1 and the bracket 10. This depends on the position of the end face of the positioning turntable 6. When the end face of the positioning turntable 6 near the positioning component 7 is flush with the end face of the bracket 10, the pin 7-1 can be directly inserted into the positioning hole 6-1 on the positioning turntable 6. As for the snap-fit ​​relationship between the connecting plate 7-3 and the bracket 10, a tenon and mortise snap-fit ​​structure can be used. The shape and other configurations can be made according to actual needs, as long as they do not affect the movement and reset of the pin 7-1. No specific restrictions are imposed here.

[0053] The following is with reference to the appendix. Figure 3 The connection and assembly form between the positioning element 7 and the bracket 10 shown in the illustration continues to describe this embodiment. However, as stated above, the following embodiments are exemplary and not restrictive, and should not be construed as limiting the scope of protection of this application. The end face of the bracket 10 facing away from the water distribution pipe 1 is provided with a connecting plate mounting groove 10-21, a return spring mounting groove 10-22, and a pin mounting hole 10-23 that penetrates the bracket 10 laterally. The positioning hole 6-1 on the positioning turntable 6 is shaped and corresponds to the pin mounting hole 10-23 (here, the corresponding position means that the axial distance between the positioning hole 6-1 and the positioning turntable 6 is equal to the axial distance between the pin mounting hole 10-23 and the positioning turntable 6). At least two sets of return spring mounting grooves 10-22 are evenly arranged around the pin mounting hole 10-23. Therefore, the connecting plate 7-3 is provided with at least two sets of return springs 7-2 evenly distributed around the pin 7-1 to strengthen the clamping force on the pin 7-1.

[0054] For ease of operation, a handle 7-4 can be provided on the side of the connecting plate 7-3 opposite to the return spring 7-2. The configuration of the handle 7-4 can be configured according to actual usage requirements, and no specific restrictions are imposed here.

[0055] Generally, before rotating the water distribution pipe 1, both ends of the water distribution pipe 1 need to be separated from the pin 7-1. However, the water distribution pipe 1 is relatively long, and one person cannot operate the pins 7-1 at both ends simultaneously. Therefore, a stop groove 10-24 can be set on the bracket 10 near the connecting plate mounting groove 10-21. The stop groove 10-24 extends radially along the pin 7-1 to connect with the connecting plate mounting groove 10-21. A slidable stop 8 is constructed in the stop groove 10-24. The stop 8 is located outside the pin 7-1. When the connecting plate 7-3 is moved to disengage the pin 7-1 from the positioning hole 6-1, the connecting plate 7-3... When a gap appears between the connecting plate and the mounting groove 10-21, the sliding stop 8 is moved at least partially into the mounting groove 10-21 to fill the gap. This prevents the connecting plate 7-3 from resetting under the action of the return spring 7-2 after the operator releases the handle. The operator then moves the connecting plate 7-3 to the other end of the water distribution pipe 1, rotates the water distribution pipe 1, and releases the handle to connect the pin 7-1 with the positioning hole 6-1 on the angled positioning turntable 6. Then, the operator returns to the side of the connecting plate 7-3 that was blocked by the stop 8, slides the stop 8 away from the pin 7-1, and releases the handle to reset the connecting plate 7-3.

[0056] In the above, the stop block 8 can be a straight or L-shaped structure. To facilitate hand gripping and sliding of the stop block 8, the end opening of the stop block groove 10-24 is away from the connecting plate mounting groove 10-21, or the side opening of the stop block groove 10-24 is away from the positioning turntable 6, so that part of the structure of the stop block 8 extends out of the stop block groove 10-24. When the stop block groove 10-24 is away from the end opening of the connecting plate mounting groove 10-21, the stop block 8 can be a straight-line structure, and the length of the stop block 8 should meet the following requirements: when the stop block 8 is pushed into the connecting plate mounting groove 10-21, a portion of the end of the stop block 8 away from the connecting plate mounting groove 10-21 still protrudes outside the stop block groove 10-24, so that in this case, a person can grasp the stop block 8 and pull it out of the connecting plate mounting groove 10-21; when the stop block groove 10-24 is away from the side opening of the positioning turntable 6, the stop block 8 can be an L-shaped structure, with the long end of the stop block 8 slidingly disposed in the stop block groove 10-24, and the short end protruding outside the stop block groove 10-24, so that a person can grasp and slide it. (See attached document) Figure 4-7When the stop block 8 adopts an L-shaped structure, its short end can be configured as a V-shaped spring piece 9, and an I-shaped slide 10-25 is configured on the side of the stop block slide groove 10-24 away from the positioning turntable 6. The I-shaped slide 10-25 has an opening on the side away from the stop block slide groove 10-24. The I-shaped slide 10-25 has a "|" part located in the center and two sets of "—" parts located at the ends. The "|" part of the I-shaped slide 10-24 extends in the same direction as the long end of the stop block 8. The V-shaped spring piece 9 is placed in the I-shaped slide 10-25. The closed end of the V-shaped spring piece 9 is fixed to the stop block 8, and the open end is away from the stop block 8. When the V-shaped spring 9 is located at the "-" part of the I-shaped slide 10-25, the V-shaped spring 9 automatically unfolds, preventing the stop block 8 from sliding freely in the stop block groove 10-24. When the V-shaped spring 9 is pinched, a person can move the V-shaped spring 9 at the "|" part of the I-shaped slide 10-25, thereby causing the stop block 8 to slide in the stop block groove 10-24. The above-mentioned structures, such as the stop block 8, the stop block groove 10-24, the I-shaped slide 10-25, and the V-shaped spring 9, can be configured in multiple sets according to actual needs.

[0057] In this embodiment, the support 10 includes: support legs 10-1, stabilizing beams 10-3, cross braces 10-4, and diagonal braces 10-5. Two sets of support legs 10-1 are arranged opposite each other, and each set of support legs 10-1 has a mounting block 10-2 for installing the water distribution pipe 1 on its top. The cross braces 10-4 are located at the bottom of the support legs 10-1 and can be an integrally formed plate or two sets of rods independently connecting the two sets of support legs 10-1. The stabilizing beams 10-3 are located between the two sets of support legs 10-1, with both ends connected to the two sets of support legs 10-1 to improve stability and prevent the tops of the support legs 10-1 from shaking or vibrating. The number of stabilizing beams 10-3 can be configured according to actual usage requirements and is not specifically limited here. The diagonal braces 10-5 are arranged diagonally, with both ends connected to the support legs 10-1 and the cross braces 10-4, forming a triangular stabilizing structure to improve the support stability of the support 10.

[0058] Depending on the specific application requirements, the outrigger 10-1 can be configured as a rod of fixed length, or as a combination of a sliding sleeve 10-11 and a sleeve 2 10-12, and a positioning element 2 10-13 to restrict the sliding of sleeve 10-11 (or sleeve 2 10-12). Either sleeve 10-11 or sleeve 2 10-12 is positioned above the other, or one is inside the other. When the side walls of sleeve 10-11 and sleeve 2 10-12 are respectively provided with several height adjustment holes 10-14, the positioning element 2 10-13 can be configured as a bolt or pin, allowing for manual adjustment of sleeve 10-11 and sleeve 2 10-12. The total height of the outrigger 10-1 can be adjusted by installing bolts or pins in different height adjustment holes 10-14 to adapt to different flushing needs. Of course, the positioning component 2 10-13 can also be configured as a cylinder or hydraulic rod (not shown in the attached figure). When the output end of the cylinder or hydraulic rod is fixedly connected to the inner sleeve 10-11 (or sleeve 2 10-12), the cylinder or hydraulic rod can not only restrict the sliding of sleeve 10-11 (or sleeve 2 10-12) when the action stops, but also drive the sliding of sleeve 10-11 (or sleeve 2 10-12) when it is extended or retracted, thereby adjusting the total height of the outrigger 10-1 to adapt to different flushing needs.

[0059] When the outrigger 10-1 is configured in a height-adjustable configuration, one of the outrigger 10-1 and the cross brace 10-4 is rotatably connected to the first end of the diagonal brace 10-5; the other is rotatably connected to the second end of the diagonal brace 10-5. Alternatively, several locking blocks 10-6 are provided, which are radially distributed along the rotation axis of the diagonal brace 10-5. The second end of the diagonal brace 10-5 is locked with the locking blocks 10-6. In the former case, the diagonal brace 10-5 can be a telescopic rod with a self-locking function. In the latter case, the diagonal brace 10-5 can be either a telescopic rod with a self-locking function or a regular fixed rod.

[0060] Compared with the prior art, the beneficial effects of this utility model are as follows: It provides a novel guide wheel rinsing device to work with CNC grooving machine tools. After the guide wheel is grooved, high-pressure water is used to rinse the surface of the guide wheel to remove dirt and prevent it from affecting the stability, structure and slicing quality of diamond wire when used in wire cutting machines. In addition, the angle of the rinsing nozzle 3 can be adjusted by rotating the water distribution pipe 1, and the height of the rinsing nozzle 3 can be adjusted by the telescopic support leg 10-1 to adapt to various working conditions. The characteristically designed adjustment structure improves the ease of operation and adjustment efficiency during the adjustment process.

[0061] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
