Description

Technical Field

[0001] This invention relates to the field of diamond wire stretching technology, and more particularly to a diamond wire busbar stretching and impurity removal device. Background Technology

[0002] In the manufacturing process of diamond wire cutting, the quality of the busbar material is crucial. During the drawing and forming process, numerous impurities inevitably adhere to or generate on the surface of the diamond wire busbar, such as metal fragments from the wear of the drawing die, lubricant residue, and environmental dust. If these surface impurities are not effectively removed, they will seriously affect the subsequent electroplating process, leading to insufficient adhesion between the plating layer and the busbar substrate. This, in turn, can cause a series of quality problems, including plating layer peeling, poor diamond micropowder bonding (i.e., poor "sanding" effect), and increased wire breakage rate during the cutting process. Ultimately, these issues affect the cutting quality and production efficiency of materials such as silicon wafers.

[0003] Patent application publication number CN110180915B discloses a diamond wire busbar stretching and impurity removal device, including a spacer plate. The upper surface of the spacer plate includes a fixed plate, the bottom of which is fixedly connected to the upper surface of the spacer plate. The right side of the fixed plate includes a hydraulic telescopic rod, the left end of which is fixedly connected to the right side of the fixed plate. This diamond wire busbar stretching and impurity removal device, through the cooperation of a motor, bolts, and a threaded ring, achieves left and right movement of the motor by having the bolts move left and right inside the threaded ring. Through the cooperation of a vertical rod, slider, groove, connecting rod, rotating shaft, and cleaning roller, the cleaning roller moves left and right simultaneously with the motor, removing debris and dust from the surface of the diamond wire busbar. This solves the problem of debris and dust easily generated during the current diamond wire busbar stretching process.

[0004] However, the cleaning roller in the above device is located above the diamond wire busbar. When the cleaning roller rotates to clean the diamond wire busbar, it can only clean the surface above the diamond wire busbar, while the surface below the diamond wire busbar is difficult to clean. Therefore, it is impossible to clean all the impurities on the surface of the diamond wire busbar, which is a defect. Summary of the Invention

Two connecting frames are fixedly connected to the back of the central plate. Slide rods are provided inside the two connecting frames. First springs are sleeved on both sides of the surface of the slide rods. One end of the two first springs is connected to the two sides of the inner wall of the connecting frame, respectively. An array of embedded grooves is opened on the surface of the central plate. A threaded rod is threaded through the top of the embedded groove. A positioning block that matches the embedded groove is rotatably connected to the bottom of the threaded rod through a bearing. A sponge is provided at one end of the positioning block.

[0007] As a further description of the diamond wire busbar stretching and impurity removal device described above: a protrusion is provided on the other side of the movable frame, and movable plates are fixedly connected to the top and bottom of the movable frame. The movable plates are slidably connected to the slide rod, and the two sides of the movable plates are respectively connected to one end of two springs.

[0008] As a further description of the diamond wire busbar stretching and impurity removal device described above: The impurity removal mechanism includes a double-layered tank slidably connected inside the second positioning plate. The double-layered tank is divided into an outer tank and an inner tank. Wire holes are opened on both sides of the inner tank. A rotating plate is rotatably connected to one side of the inner tank. One side of the rotating plate is fixedly connected to the center plate through a connecting rod. Brush bristles are provided inside the inner tank. Impurity leakage grooves are opened on the double-layered tank. A scraper is fixedly connected to one side of the outer tank. An outer protrusion is fixedly connected to the edge of one side of the inner tank.

[0009] As a further description of the diamond wire busbar stretching and impurity removal device of the above-mentioned technology: the scraper includes a bending rod connected to the outer tank body, a release groove is opened on the surface of the bending rod, a side groove is opened on one side of the bending rod, an extension plate is slidably connected inside the side groove, a through rod is fixedly connected to the top of the extension plate, the top of the through rod passes through the top of the side groove and is connected to a top plate, a second spring is provided between the top of the extension plate and the inner top wall of the side groove, and the second spring is sleeved on the surface of the through rod.

[0010] As a further description of the diamond wire busbar stretching and impurity removal device described above: the drive mechanism includes a motor mounted on the upper surface of a support plate, the output end of the motor is connected to a gear, the tooth surface of the gear meshes with a gear ring, and the gear ring is fixedly connected to the outer tank.

[0011] As a further description of the diamond wire busbar stretching and impurity removal device of the above-mentioned technology: one side of the extension plate is flush with the edge of the side groove opening, and one side of the extension plate is in contact with the front of the positioning block.

[0012] As a further description of the diamond wire busbar stretching and impurity removal device of the above technology: the front of the center plate is provided with a number of scales, which are distributed on the edges of the inner groove on both sides.

[0013] As a further description of the diamond wire busbar stretching and impurity removal device of the above-mentioned technology: both sides of the outer shell are fixedly connected to the inlet shell, the inside of the inlet shell is fixedly connected to the support pulley, and the top of the outer shell is slidably connected to the cover plate.

[0014] In summary, due to the adoption of the above-mentioned technology in the diamond wire busbar stretching and impurity removal device, the beneficial effects of this invention are: With the inclusion of a cleaning mechanism, a driving mechanism, and a positioning mechanism, the busbar is sequentially passed through the center plate and the inside of the double-layer tank during use. Rotating the threaded rod moves the positioning blocks towards the center of the center plate. The three positioning blocks, along with a sponge, clamp the busbar, positioning it at the center of the center plate. This prevents the busbar from skewing during transport, which would affect the cleaning effect. Simultaneously, due to the sponge's soft nature, it adheres to the outer surface of the busbar. As the busbar is continuously pulled, the three positioning blocks and the sponge remove impurities from the outer surface. In conjunction with the brush inside the double-layer tank, as the busbar passes through the inner tank, the brush further cleans any remaining impurities from the outer surface. The removed impurities fall out of the outer tank through the impurity trough, thus performing double cleaning of the busbar and thoroughly cleaning impurities from its surface, significantly improving the cleaning effect. Simultaneously, when the drive mechanism drives the double-layer tank, the bristles inside the inner tank can evenly clean impurities on the busbar. At the same time, when the double-layer tank rotates, the outer tank can drive the scraper and the outer protrusion to rotate. The scraper and the outer protrusion are respectively set opposite each other on the outer tank. As the outer protrusion continuously contacts one of the protrusions, the outer protrusion can pull the moving frame to move horizontally to one side. When the widest part of the outer protrusion contacts the protrusion, one end of the moving frame disengages from the first positioning plate, thus allowing the scraper to pass smoothly and avoiding the moving frame from blocking the scraper's rotation. When the scraper rotates, it can scrape off the impurities on the surface of the positioning block, thereby scraping off the impurities accumulated on the positioning block and preventing the accumulated impurities from increasing the resistance of the busbar.

[0017] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a diamond wire busbar stretching and impurity removal device of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figures 1-9This embodiment provides a diamond wire busbar stretching and impurity removal device, including a housing 1. Both sides of the housing 1 are fixedly connected to inlet shells 8. The inside of the inlet shells 8 is fixedly connected to a support pulley 9. The top of the housing 1 is slidably connected to a cover plate 10. One side of the inner wall of the housing 1 is fixedly connected to a first positioning plate 2. The back of the first positioning plate 2 is slidably connected to a positioning mechanism 7. The other side of the inner wall of the housing 1 is fixedly connected to a second positioning plate 3. The inside of the second positioning plate 3 is rotatably connected to a cleanup mechanism 4. A support plate 5 is fixedly connected to the outer surface of the housing 1. The upper surface of the support plate 5 is fixedly connected to a drive mechanism 6.

[0019] Specifically, such as Figure 1 and Figure 4 As shown, the positioning mechanism 7 includes a movable frame 701 slidably connected to the back of the first positioning plate 2. A protrusion is provided on the other side of the movable frame 701. Movable plates 708 are fixedly connected to the top and bottom of the movable frame 701. The movable plates 708 are slidably connected to the slide rod, and both sides of the movable plates 708 are respectively connected to one end of two springs. A center plate 702 is slidably connected to one side of the movable frame 701. Two connecting brackets 703 are fixedly connected to the back of the center plate 702. Slide rods are provided inside the two connecting brackets 703. First springs 704 are sleeved on both sides of the surface of the slide rods. One end of the two first springs 704 is respectively connected to both sides of the inner wall of the connecting brackets 703. Embedded grooves are arrayed on the center plate 702, and the top of the embedded grooves is threaded. A threaded rod 705 is inserted, and the bottom of the threaded rod 705 is rotatably connected to a positioning block 706 that matches the embedded groove via a bearing. A sponge 707 is provided at one end of the positioning block 706. First, the busbar passes through the middle of the center plate 702. Then, the threaded rod 705 is rotated to move the positioning block 706 toward the center of the center plate 702. The three positioning blocks 706 cause the sponge 707 to fit against the outer surface of the busbar, positioning the busbar at the center of the center plate 702. This prevents the busbar from becoming skewed during transport, which would affect the impurity removal effect. At the same time, due to the soft nature of the sponge 707, the sponge 707 can fit against the outer surface of the busbar to the maximum extent. As the busbar is continuously pulled, the three positioning blocks 706 and the sponge 707 remove impurities from the outer surface of the busbar. The front of the center plate 702 is arrayed with several scales, which are distributed on the edges of the two sides of the embedded groove. By setting the scales, the distances moved by the three positioning blocks 706 can be compared and observed, so as to make the distances moved by the three positioning blocks 706 equal and avoid the busbar from being skewed due to the different distances moved by the three positioning blocks 706, which would prevent it from being at the center of the center plate 702 and affect the accurate removal of impurities from the busbar.

[0020] Specifically, such as Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the cleaning mechanism 4 includes a double-layer tank 401 slidably connected inside the second positioning plate 3. The double-layer tank 401 is divided into an outer tank and an inner tank. A rotating plate 405 is rotatably connected to one side of the inner tank. One side of the rotating plate 405 is fixedly connected to the center plate 702 via a connecting rod. The rotating plate 405 is connected to the center plate 702 via the connecting rod, which allows the center plate 702 and the double-layer tank 401 to be at the same center, preventing the center plate 702 from shifting laterally when the moving frame 701 is moved. Wire holes are provided on both sides of the inner tank, and bristles 404 are provided inside the inner tank. The tank 401 has a debris-leakage groove. A scraper 402 is fixedly connected to one side of the outer tank body, and an outer protrusion 403 is fixedly connected to the edge of one side of the inner tank body. When the busbar passes through the inside of the center plate 702, it enters the inner tank body through a wire hole on one side, and then exits through a wire hole on the other side. As the busbar passes through the inner tank body, the bristles 404 inside the inner tank body clean the impurities that have not been removed from the outer surface of the busbar again. The cleaned impurities fall out of the debris-leakage groove to the outside of the outer tank body. When the double-layer tank 401 rotates, it drives the bristles 404 inside the inner tank body to rotate. 4. It can evenly clean impurities on the busbar. Simultaneously, while the three positioning blocks 706 perform initial cleaning of the impurities on the busbar, as the busbar is continuously pulled, the positioning blocks 706 gradually transfer and accumulate the impurities removed from the busbar on one side of the positioning block 706 in contact with the busbar. This accumulation of impurities increases the resistance to pulling the busbar. One end of the scraper 402 passes between the center plate 702 and the first positioning plate 2 and adheres to the side of the positioning block 706 where impurities are accumulated. Therefore, when the double-layer tank 401 rotates, the outer tank body can drive the scraper 402 and the outer protrusion 403 to rotate. 03 are respectively set on the outer tank body. As the outer protrusion 403 continuously contacts one of the protrusions, the outer protrusion 403 can pull the moving frame 701 to move horizontally to one side. When the widest part of the outer protrusion 403 contacts the protrusion, one end of the moving frame 701 is separated from the first positioning plate 2, so that the scraper 402 can pass smoothly and avoid the moving frame 701 blocking the scraper 402 from rotating. When the scraper 402 rotates, it can scrape off the impurities on the surface of the positioning block 706, thereby scraping off the impurities accumulated on the positioning block 706 and avoiding the accumulated impurities from increasing the resistance of the busbar pulling. The scraper 402 includes a bent rod 4021 connected to the outer tank body. A release groove is provided on the surface of the bent rod 4021. A side groove is provided on one side of the bent rod 4021. An extension plate 4022 is slidably connected inside the side groove. A through rod 4023 is fixedly connected to the top of the extension plate 4022. The top of the through rod 4023 passes through the top of the side groove and is connected to a top plate. A second spring 4024 is provided between the top of the extension plate 4022 and the top wall of the side groove. The second spring 4024 is sleeved on the surface of the through rod 4023. Since the thickness of the generatrix is ​​different, the distance that the positioning block 706 moves will also be different. Through the setting of the extension plate 4022 and the second spring 4024, the bent rod 4021 can be extended in coordination with the distance that the positioning block 706 moves, avoiding the possibility of missing scraping when cleaning the impurities accumulated on the positioning block 706 due to the insufficient length of the bent rod 4021. One side of the extension plate 4022 is flush with the edge of the side groove opening, and one side of the extension plate 4022 is in contact with the front of the positioning block 706. The edge of the extension plate 4022 is flush with the edge of the side groove opening. If the width of the extension plate 4022 and the width of the bending rod 4021 are not uniform, the extension plate 4022 will not be able to fit the surface of the positioning block 706, which will affect the effect of the bending rod 4021 on scraping impurities.

[0021] Specifically, such as Figure 3 and Figure 4 As shown, the drive mechanism 6 includes a motor 601 mounted on the upper surface of the support plate 5. The output end of the motor 601 is connected to a gear 602. The tooth surface of the gear 602 meshes with a gear ring 603, which is fixedly connected to the outer tank.

[0022] Among them, the motor 601 starts and drives the gear 602 to rotate, then the gear 602 rotates and drives the gear ring 603 to rotate, and the gear ring 603 rotates and drives the double-layer tank 401 to rotate.

[0023] Working principle: First, the busbar is inserted from one side of the outer shell 1, then passes through the center plate 702 and the inside of the double-layer tank 401 in sequence, and finally exits from the other side of the outer shell 1. When the busbar passes through the center plate 702, the threaded rod 705 is rotated to drive the positioning block 706 to move towards the center of the center plate 702. The three positioning blocks 706 drive the sponge 707 to fit against the outer surface of the busbar, positioning the busbar at the center of the center plate 702, preventing the busbar from becoming skewed during transportation, which would affect the impurity removal effect. At the same time, due to the soft nature of the sponge 707, the sponge 707 can fit against the outer surface of the busbar to the maximum extent. As the busbar is continuously pulled, the three positioning blocks 706 and the sponge 707 remove impurities from the outer surface of the busbar.

[0024] As the busbar passes through the inner tank, the bristles 404 inside the inner tank clean the remaining impurities on the outer surface of the busbar. The cleaned impurities fall out of the outer tank through the impurity trough. Then, the motor 601 starts and drives the gear 602 to rotate. Subsequently, the rotation of the gear 602 drives the gear ring 603 to rotate, which in turn drives the double-layer tank 401 to rotate. When the double-layer tank 401 rotates, it drives the bristles 404 inside the inner tank to rotate. The rotating bristles 404 can evenly clean the impurities on the busbar.

[0025] Simultaneously, while the three positioning blocks 706 perform initial cleaning of impurities on the busbar, as the busbar is continuously pulled, the positioning blocks 706 gradually transfer and accumulate the impurities removed from the busbar on the side where they contact the busbar. This accumulation of impurities increases the resistance to the busbar's movement. One end of the scraper 402 passes between the center plate 702 and the first positioning plate 2 and adheres to the side of the positioning block 706 where impurities are accumulated. Therefore, when the double-layer tank 401 rotates, the outer tank can drive the scraper 402 and the outer protrusion 403 to rotate. The scraper 402 and the outer protrusion 403 are respectively positioned opposite each other. On the outer tank, as the outer protrusion 403 continuously contacts one of the protrusions, the outer protrusion 403 can pull the moving frame 701 to move horizontally to one side. When the widest part of the outer protrusion 403 contacts the protrusion, one end of the moving frame 701 disengages from the first positioning plate 2, thereby allowing the scraper 402 to pass smoothly. This avoids the moving frame 701 blocking the scraper 402 from rotating. When the scraper 402 rotates, it can scrape off the impurities on the surface of the positioning block 706, thereby scraping off the impurities accumulated on the positioning block 706 and preventing the accumulated impurities from increasing the resistance of the busbar pulling.
