Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of filter mesh etching positioning, in particular to a filter mesh etching positioning device. Background Art
[0002] Etching is a technique that removes materials by chemical reaction or physical impact. Etching technology can be divided into two categories: wet etching and dry etching. Dry etching mainly uses argon gas to bombard the surface of semi-finished materials, achieving the purpose of etching through collisions between particles.
[0003] When performing dry etching on filter mesh, clamping the metal sheet is a crucial step. Since the metal sheet itself is thin and its raw material strength is relatively low, it is very easy to deform during the processing. In order to ensure that the metal sheet can remain stable during the etching process, the traditional fixture design often uses clamps on both sides to clamp the raw material. The operator needs to manually adjust the distance between the clamps on both sides to keep the metal sheet as straight as possible, thereby ensuring the accuracy and effect of etching.
[0004] However, this traditional clamp design has some problems. Since the clamp block of the clamp is relatively hard and the clamping force is often relatively large, when the clamp block clamps the metal sheet, it is easy to produce a certain deformation at the outer part of the metal sheet. This deformation will not only affect the etching accuracy, but also reduce the quality of the filter mesh, resulting in the problem of unqualified quality of the subsequent etched filter mesh.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0022] Embodiment 1: Figures 1 to 6 As shown, a positioning device for etching a filter mesh described in an embodiment of the present invention includes a body 1, a driving motor 2 is fixedly connected to one side of the body 1, the driving motor 2 drives an etching roller, the etching roller is used to eject an ion beam, and physically or chemically react with the surface of the filter mesh, thereby removing the material, and then forming specific filter holes on the surface of the filter plate 5, an adjustment component is arranged above the body 1, the adjustment component includes a fixing frame 3, a fixing motor 31 is fixedly connected to the upper surface of the fixing frame 3, and a screw rod 32 is fixedly connected to the output end of the fixing motor 31, The screw rod 32 reciprocates and drives a fixed shaft 36, and the circumferential surface of the fixed shaft 36 is used to sleeve an auxiliary roller, which is used to assist the etching roller in positioning the filter plate 5 during the etching process; a striking assembly is arranged above the body 1, and the striking assembly includes two rack plates 24 slidably arranged on both sides of the body 1, and the upper surfaces of the two rack plates 24 are fixedly connected to the same connecting frame 216, and the lower surface of the connecting frame 216 is elastically provided with a plurality of top blocks 220, and the plurality of top blocks 220 are used to eject the metal sheets that have not completely separated from the filter plate 5 after etching.
[0023] Specifically, there are some problems with the existing clamp design. Since the clamp block of the clamp is relatively hard and the clamping force is often relatively large, when the clamp block clamps the metal sheet, it is easy to produce a certain deformation at the outer part of the metal sheet. This deformation not only affects the etching accuracy, but also reduces the quality of the filter mesh, resulting in the problem of unqualified quality of the filter mesh etched later. Therefore, the present invention solves this problem by setting a certain structure. First, when the device is running, the driving motor 2 drives the etching roller to rotate. The etching roller acts on the surface of the filter mesh by ejecting ion beams to accurately remove materials and form the required filter holes. At the same time, the fixed motor 31 in the adjustment component drives the screw 32 to rotate, so that the fixed shaft 36 drives the auxiliary roller to fit tightly with the metal filter plate 5 of the corresponding specifications. The auxiliary roller fits tightly on the surface of the filter plate 5 to ensure the stable positioning of the filter plate 5 during the etching process and improve the etching accuracy. When a group of holes are etched, the front striking component plays a role, and the two rack plates 24 slide on both sides of the body 1. The connecting frame 216 and the top block 220 below it move downward, and the top block 220 uses elastic force to eject the metal sheet that has not completely separated from the filter plate 5 after etching, so as to avoid the residual metal sheet affecting the subsequent operation or product quality. The positioning device realizes accurate positioning during the etching process and effective cleaning after etching through the design of the adjustment component and the striking component, thereby improving the etching quality and production efficiency of the filter mesh. The reciprocating movement of the auxiliary roller not only enhances the stability of the filter plate 5, but also ensures the accuracy of the etching hole position. At the same time, the elastic ejection effect of the top block 220 effectively solves the problem of residual metal sheets and reduces the tediousness and cost of manual cleaning. The problem that the existing positioning and clamping may cause deformation of the metal filter plate 5, resulting in unqualified subsequent etching quality is solved.
[0024] like Figure 3 As shown, the adjustment component of this embodiment also includes a rotating wheel 38 fixedly connected to one end of the screw rod 32, and the fixed motor 31 drives the rotating wheel 38 at the top of one of the screw rods 32 to rotate, and the rotating wheel 38 drives the conveyor belt 33 to drive the other screw rod 32 to rotate. The circumferential surfaces of the two screw rods 32 are slidably connected with sliding blocks 35, and the body 1 is provided with a limiting groove 34 at the position corresponding to the sliding block 35. The sliding block 35 can slide along the limiting groove 34, and a fixed shaft 36 is fixedly connected between the two sliding blocks 35. Auxiliary rollers are sleeved on the circumferential surface of the fixed shaft 36. The bottom end of each sliding block 35 is fixedly connected to a connecting spring 37, and the connecting spring 37 is used to adjust the distance between the auxiliary roller and the etching roller to adapt to filter plates 5 of different specifications and position the corresponding filter plates 5.
[0025] Specifically, the fixed motor 31 drives the rotating wheel 38 at the top of one of the screw rods 32 to rotate, and the rotating wheel 38 drives the other screw rod 32 to rotate synchronously through the conveyor belt 33 to realize dual-axis synchronous driving. The sliding blocks 35 on the two screw rods 32 slide on the circumferential surface and are restricted by the limiting groove 34 opened in the body 1 to ensure that the sliding blocks 35 move along a specific trajectory. The fixed shaft 36 fixed between the sliding blocks 35 drives the auxiliary roller to move to adapt to filter plates 5 of different widths. The setting of the connecting spring 37 allows the sliding block 35 and the auxiliary roller thereon to have a certain elastic adjustment ability in the vertical direction, and automatically adjusts the distance between the auxiliary roller and the etching roller according to the thickness of the filter plate 5 to ensure that the auxiliary roller always fits closely to the edge of the filter plate 5 to provide stable positioning support.
[0026] like Figure 2 As shown, the striking assembly of this embodiment also includes a cam 21, and the driving motor 2 drives the cam 21 to rotate. The cam 21 is engaged with a gear 22, and the circumferential surface of the shaft rod fixedly connected to the gear 22 is fixedly connected to an etching roller. The cam 21 is engaged with a rack plate 24, and the connecting frame 216 is fixedly connected to the two rack plates 24.
[0027] Specifically, the driving motor 2 drives the cam 21 to rotate, and the cam 21 drives the gear 22 to rotate through the meshing action, thereby driving the etching roller fixed on its shaft to perform periodic motion. At the same time, the cam 21 also meshes with the rack plate 24, and the rack plate 24 moves upward as the cam 21 rotates. The striking action of the top block 220 is realized through the connecting frame 216, thereby realizing the periodic striking motion of the etching roller and improving the etching efficiency and uniformity.
[0028] like Figure 2 As shown, sliding grooves 23 are provided on both sides of the body 1 of this embodiment, and the rack plate 24 can slide up and down along the sliding grooves 23. A bottom plate 25 is fixedly connected to the lower surface of the body 1, and a telescopic rod 26 is fixedly connected to the upper surface of the bottom plate 25. The circumferential surface of the telescopic rod 26 is sleeved with a compression spring 27, and the top end of the compression spring 27 is fixedly connected to the rack plate 24.
[0029] Specifically, the sliding grooves 23 opened on both sides of the body 1 provide a track for the rack plate 24 to slide up and down, ensuring that the rack plate 24 can move stably and accurately under the drive of the cam 21. The telescopic rod 26 on the bottom plate 25 is connected to the rack plate 24 through a compression spring 27. The compression spring 27 serves as an elastic element and plays a role of buffering and resetting when the rack plate 24 slides up and down, so that the rack plate 24 can smoothly transition when it is driven by the cam 21, and can quickly return to its initial position after the driving force disappears, driving a number of top blocks 220 to clear the holes and grooves of the filter plate 5, thereby enhancing the stability and accuracy of the movement of the rack plate 24, and reducing the impact and noise during the movement through the buffering effect of the compression spring 27, thereby extending the service life of the equipment.
[0030] like Figure 2 As shown, the driving motor 2 of this embodiment drives the cam 21 to rotate, and the cam 21 can drive the gear 22 to rotate after rotating. The rotation of the gear 22 drives the etching roller to rotate, and the etching roller etches the surface of the filter plate 5. Some of the gear teeth of the cam 21 can control the intermittent etching of the filter plate 5. The etched holes have a certain interval. The rotation of the cam 21 can also drive the rack plate 24 to move upward. When the non-toothed part of the cam 21 is engaged with the rack plate 24, the rack plate 24 moves downward under the reset force of the compression spring 27, driving the connecting frame 216, and at the same time driving a plurality of ejecting blocks 220 elastically arranged on the connecting frame 216 to eject and detach the metal sheet that has not been detached from the surface of the filter plate 5.
[0031] Specifically, after the driving motor 2 is started, the cam 21 rotates with it, thereby driving the gear 22 meshing with it to rotate. The rotation of the gear 22 drives the periodic rotation of the etching roller. During the rotation process, the etching roller etches the surface of the filter plate 5 to form holes at a certain interval. The special design of the cam 21, some of its gear teeth can achieve intermittent control of the etching of the filter plate 5, ensuring that the etching holes have a uniform interval. At the same time, the rotation of the cam 21 also drives the rack plate 24 to move up and down in the sliding groove 23. When the gear of the cam 21 is disengaged from the rack plate 24, the rack plate 24 moves downward rapidly under the reset force of the compression spring 27. This action is transmitted through the connecting frame 216, so that a plurality of ejecting blocks 220 elastically arranged on the connecting frame 216 eject the metal sheets that have not yet been separated from the surface of the filter plate 5, thereby ensuring the thoroughness of the etching effect and improving the accuracy and efficiency of the etching operation. The problem of residual metal sheets on the surface of the filter plate 5 is effectively solved through intermittent etching and the ejection design of the ejecting block 220, thereby improving the etching quality.
[0032] Embodiment 2: Figures 1 to 6 As shown, compared with Example 1, another embodiment of the present invention is: a plurality of slide rods 217 are slidably connected to the upper surface of the connecting frame 216, the top of each slide rod 217 is fixedly connected to a limiting plate 218, the lower surface of each limiting plate 218 is fixedly connected to two second springs 219, the bottom ends of the two second springs 219 are fixedly connected to the connecting frame 216, and the bottom end of each slide rod 217 is fixedly connected to a top block 220.
[0033] Specifically, the slide bar 217 on the upper surface of the connecting frame 216 can slide freely, and the limit plate 218 fixed at the top is connected to the connecting frame 216 through the second spring 219 to form an elastic support. When the rack plate 24 drives the connecting frame 216 to move, the slide bar 217 and the top block 220 at the bottom move accordingly. At the same time, the second spring 219 generates corresponding elastic force according to the moving distance to ensure that the top block 220 maintains appropriate contact force with the surface of the filter plate 5. The top block 220 has an ejection effect on the metal sheet on the surface of the filter plate 5. The elastic adjustment of the second spring 219 also realizes precise control of the force of the top block 220, avoids damage to the filter plate 5 due to excessive force, and improves the quality of the etching operation and the reliability of the equipment.
[0034] like Figure 5 As shown, the rack plate 24 of this embodiment drives the connecting frame 216 to move upward. When the cam 21 is no longer engaged with the rack plate 24, the rack plate 24 moves downward under the restoring force of the compression spring 27, and the rack plate 24 drives a plurality of top blocks 220 on the connecting frame 216 to strike and impact the holes etched on the surface of the filter plate 5, and push out the metal sheets that have not been detached from the holes. The top blocks 220 push the metal sheets, and when they encounter metal sheets adhered to the filter plate 5, the metal sheets will squeeze the top blocks 220. The top blocks 220 push the sliding rod 217, driving the sliding rod to push the second spring 219. The second spring 219 can exert a reaction force to increase the force of pushing up the metal sheets.
[0035] Specifically, under the drive of the cam 21, the rack plate 24 drives the connecting frame 216 to rise. When the cam 21 is separated from the rack plate 24, the rack plate 24 rapidly descends under the restoring force of the compression spring 27. This action causes the multiple top blocks 220 on the connecting frame 216 to forcefully strike the holes etched on the surface of the filter plate 5, effectively ejecting the metal sheets that have not been completely separated from the holes. If a metal sheet that is tightly adhered is encountered, the metal sheet will squeeze the top block 220, and the top block 220 will push the slide bar 217 along the connecting frame 2 16 slides, thereby compressing the second spring 219. The compression process of the spring accumulates energy, and then releases a strong reaction force, which further increases the ejection force of the metal sheet through the ejection block 220, ensuring that the metal sheet is completely separated from the filter plate 5, thereby improving the thoroughness of the metal sheet separation after etching. The energy storage and release mechanism of the spring is also used to achieve dynamic adjustment of the force of the ejection block 220, which not only ensures the ejection effect, but also avoids the damage of the filter plate 5 caused by excessive force, thereby significantly improving the quality and efficiency of the etching operation.
[0036] like Figure 5 As shown, a grinding block 221 is fixedly connected to the upper surface of the top block 220 of this embodiment. The grinding block 221 can grind the inner wall of the etched hole and remove the metal burrs adhered to the inner wall of the hole.
[0037] Specifically, the frosting block 221 fixed to the top block 220, while the top block 220 strikes and impacts the etched hole, also performs a fine grinding treatment on the inner wall of the hole. The material and structural design of the frosting block 221 enable it to effectively grind away the metal burrs adhering to the inner wall of the hole, further improving the smoothness and overall quality of the etched hole, simplifying the processing process of the metal burrs after etching, and through the grinding effect of the frosting block 221, the fine processing of the inner wall of the etched hole is achieved, reducing the subsequent processing cost, and improving the overall production efficiency and product quality.
[0038] like Figure 5 and Figure 6 As shown, a fixed box 28 is fixedly connected to the upper part of the machine body 1 of this embodiment, and a first cavity 29 is opened inside the fixed box 28. Both sides of the inner wall of the first cavity 29 are opened with fixed grooves 210, and first springs 211 are fixedly connected to the fixed grooves 210. The bottom ends of the two first springs 211 are fixedly connected to the same cross bar 215. A connecting plate 212 is fixedly connected to the lower surface of the fixed box 28, and a sliding column 214 is fixedly connected to the lower surface of the cross bar 215. The sliding column 214 slides through the connecting plate 212, and two fixed pipes 213 are fixedly connected to the position of the connecting plate 212 corresponding to each cross bar 215. The connecting frame When the limit plate 218 is driven by 216 to move upward, the limit plate 218 will push up the sliding column 214 and the cross bar 215. At this time, the cross bar 215 will break away from the seal on the top of the fixed tube 213, and the pressurized cutting fluid in the fixed box 28 will be sprayed out from the fixed tube 213 to moisten the two ends of the sanding block 221 to prevent the metal dust generated by sanding from being raised. The connecting frame 216 moves downward, and the limit plate 218 no longer squeezes the sliding column 214. The cross bar 215 is reset under the action of the restoring force of the two first springs 211, and continues to seal the top of the fixed tube 213.
[0039] Specifically, above the machine body 1, a first cavity 29 is provided inside the fixed box 28 for storing pressurized cutting fluid. Fixed grooves 210 are provided on the inner walls on both sides of the first cavity 29. The built-in first spring 211 supports the cross bar 215. The sliding column 214 connected to the lower surface of the cross bar 215 passes through the connecting plate 212 to achieve sealed sliding up and down. On the connecting plate 212, two fixed pipes 213 are installed for each position of the cross bar 215 for spraying the cutting fluid. When the drive motor 2 is started and the connecting frame 216 drives the limit plate 218 to rise, the limit plate 218 will contact the sliding column 214 and push up, thereby driving the cross bar 215 to rise. At this time, the cross bar 215 no longer seals the top of the fixed pipe 213, so that the pressurized cutting fluid in the fixed box 28 can be sprayed out from the fixed pipe 213 to directly wet the The two ends of the sanding block 221 are designed to prevent the flying of metal dust during the sanding process and maintain the cleanliness of the working environment. When the connecting frame 216 drives the limit plate 218 to descend and no longer applies pressure to the sliding column 214, the cross bar 215 is reset under the restoring force of the first spring 211, reseals the top of the fixed tube 213, and stops the spraying of the cutting fluid. The spraying of the cutting fluid and the wetting of the sanding block 221 not only effectively prevent the flying of metal dust and protect the working environment, but also reduce the friction heat between the sanding block 221 and the metal surface through the wetting effect of the cutting fluid, extend the service life of the sanding block 221, and improve the efficiency and quality of the etching operation. At the same time, the sealing design of the cross bar 215 and the fixed tube 213 ensures the on-demand supply of cutting fluid, avoids the waste of resources, and embodies the concept of environmental protection and energy saving.
[0040] like Figure 1 As shown, in this embodiment, an auxiliary plate 4 is fixedly connected to the interior of the machine body 1, and a collecting frame 41 is fixedly connected to the upper surface of the auxiliary plate 4. The collecting frame 41 is used to collect the ejected metal sheets and the flowing cutting fluid.
[0041] Specifically, inside the body 1, the auxiliary plate 4 firmly supports the collection frame 41. When the top block 220 pushes out the metal sheet and the cutting fluid flows out, they are all effectively collected in the collection frame 41, which simplifies the collection process of the metal sheet and the cutting fluid, keeps the working area clean, reduces the difficulty and cost of subsequent processing, and improves the overall operating efficiency.
[0042] Working principle: first, when the device is running, the driving motor 2 drives the etching roller to rotate. The etching roller reacts with the surface of the filter mesh by ejecting ion beams to accurately remove materials and form the required filter holes. At the same time, the fixed motor 31 in the adjustment component drives the rotating wheel 38 at the top of one of the screw rods 32 to rotate. The rotating wheel 38 drives the other screw rod 32 to rotate synchronously through the conveyor belt 33 to achieve dual-axis synchronous drive. The sliding blocks 35 on the two screw rods 32 slide on the circumferential surface and are limited by the limiting grooves 34 opened in the body 1 to ensure that the sliding blocks 35 move along a specific trajectory. The fixed shaft 36 fixed between the sliding blocks 35 drives the auxiliary roller to move to adapt to filter plates 5 of different widths. The setting of the connecting spring 37 allows the sliding block 35 and the auxiliary roller thereon to have a certain elastic adjustment ability in the vertical direction. The distance between the auxiliary roller and the etching roller is automatically adjusted according to the thickness of the filter plate 5 to ensure that the auxiliary roller always fits closely to the edge of the filter plate 5, providing stable positioning support and improving etching accuracy. After the driving motor 2 is started, the cam 21 rotates with it, thereby driving the gear 22 meshing with it to rotate. The rotation of the gear 22 drives the periodic rotation of the etching roller. During the rotation process, the etching roller etches the surface of the filter plate 5 to form holes at a certain interval. The special design of the cam 21 allows some of its gear teeth to achieve intermittent control of the etching of the filter plate 5, ensuring that the etching holes have uniform intervals. At the same time, the rotation of the cam 21 also drives the rack plate 24 to move up and down in the sliding groove 23. When the gear teeth of the cam 21 are disengaged from the rack plate 24, the rack plate 24 moves downward rapidly under the reset force of the compression spring 27. This action is transmitted through the connecting frame 216, so that the several ejecting blocks 220 elastically arranged on the connecting frame 216 eject the metal sheets that have not yet been detached from the surface of the filter plate 5, thereby ensuring the thoroughness of the etching effect and improving the accuracy and efficiency of the etching operation. The problem of residual metal sheets on the surface of the filter plate 5 is effectively solved through the intermittent etching and the ejection design of the ejecting block 220, thereby improving the etching quality. In addition, the slide bar 217 on the upper surface of the connecting frame 216 can slide freely, and the limit plate 218 fixed at the top is connected to the connecting frame 216 through the second spring 219 to form an elastic support. When the rack plate 24 drives the connecting frame 216 to move, the slide bar 217 and the top block 220 at the bottom move accordingly. At the same time, the second spring 219 generates a corresponding elastic force according to the moving distance to ensure that the top block 220 maintains an appropriate contact force with the surface of the filter plate 5. The top block 220 has an ejection effect on the metal sheet on the surface of the filter plate 5. The elastic adjustment of the second spring 219 also realizes the precise control of the force of the top block 220, avoids the damage of the filter plate 5 caused by excessive force, and improves the quality of the etching operation and the reliability of the equipment. At the same time, the frosting block 221 fixed to the top block 220 performs a fine grinding process on the inner wall of the hole while the top block 220 strikes and impacts the etched hole. The material and structural design of the frosting block 221 enable it to effectively grind away the metal burrs adhering to the inner wall of the hole, further improving the finish and overall quality of the etched hole, simplifying the process of processing the metal burrs after etching, and also achieving fine processing of the inner wall of the etched hole through the grinding effect of the frosting block 221, reducing the subsequent processing cost, and improving the overall production efficiency and product quality; And above the machine body 1, a first cavity 29 is provided inside the fixed box 28 for storing pressurized cutting fluid, and fixed grooves 210 are provided on the inner walls on both sides of the first cavity 29, and a built-in first spring 211 supports the cross bar 215, and the sliding column 214 connected to the lower surface of the cross bar 215 passes through the connecting plate 212 to achieve sealed sliding up and down, and two fixed pipes 213 are installed on the connecting plate 212 for each position of the cross bar 215 for spraying the cutting fluid, when the drive motor 2 is started, the connecting frame 216 drives the limit plate 218 to rise, the limit plate 218 will contact the sliding column 214 and push up, thereby driving the cross bar 215 to rise, and at this time the cross bar 215 no longer seals the top of the fixed pipe 213, so that the pressurized cutting fluid in the fixed box 28 can be sprayed out from the fixed pipe 213 to directly wet the grinding wheel. The two ends of the sand block 221 are designed to prevent the flying of metal dust during the sanding process and maintain the cleanliness of the working environment. When the connecting frame 216 drives the limit plate 218 to descend and no longer applies pressure to the sliding column 214, the cross bar 215 is reset under the restoring force of the first spring 211, reseals the top of the fixed tube 213, and stops the spraying of the cutting fluid. The spraying of the cutting fluid and the wetting of the sanding block 221 not only effectively prevent the flying of metal dust and protect the working environment, but also reduce the friction heat between the sanding block 221 and the metal surface through the wetting effect of the cutting fluid, extend the service life of the sanding block 221, and improve the efficiency and quality of the etching operation. At the same time, the sealing design of the cross bar 215 and the fixed tube 213 ensures the on-demand supply of cutting fluid, avoids the waste of resources, and embodies the concept of environmental protection and energy saving.
