Description

Technical Field

[0001] This utility model relates to the field of hardware etching uniformity control devices, specifically a hardware etching uniformity control device based on grain size regulation. Background Technology

[0002] Metal etching is a subtractive manufacturing technology that uses chemical reagents to selectively etch metal through a mask after exposure and development, thereby obtaining precise and complex patterns. It is widely used in the manufacture of electronic components such as lead frames and precision shielding covers, metal filters, decorative signs, and metal photomasks. Its advantages are that it has no mechanical stress, no burrs, and can process extremely thin materials and complex patterns.

[0003] While some progress has been made in devices and technologies for controlling the uniformity of metal etching based on grain size, they still face some challenges and shortcomings. Traditional metal etching devices lack the function of controlling the grain size, resulting in the mixed use of grains. During the metal etching process, the grains used have large size differences, which leads to a decrease in etching accuracy and surface quality. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, traditional metal etching equipment lacks the function of grain size control, resulting in the mixed use of grains. During the metal etching process, the grains used have large size differences, leading to problems such as reduced etching accuracy and surface quality. This utility model proposes a metal etching uniformity control device based on grain size control.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hardware etching uniformity control device based on grain size regulation, including a shell, an inlet is provided on one side of the shell, and a material distribution mechanism is provided in the inner cavity of the shell. The material distribution mechanism includes a first rotating shaft, one end of which is rotatably connected to the inner cavity of the outer casing. A first screen plate is fixedly connected to the surface of the first rotating shaft, and the surface of the first screen plate is rotatably connected to the inner cavity of the outer casing. A first gear is fixedly connected to the surface of the first rotating shaft. A second rotating shaft is rotatably connected to the inner cavity of the outer casing. A second screen plate is fixedly connected to the surface of the second rotating shaft, and a second gear is fixedly connected to the surface of the second rotating shaft. A rack is slidably connected to the inner cavity of the outer casing. The teeth of the rack mesh with the teeth of the first gear and the teeth of the rack mesh with the teeth of the second gear. A discharge port is provided on one side of the outer casing, and a transmission mechanism is provided in the inner cavity of the outer casing.

[0006] Preferably, the transmission mechanism includes a first motor, one side of which is fixedly connected to the inner wall of the housing, the output end of which is fixedly connected to a first rotating shaft, and one end of which is fixedly connected to a third gear, the teeth of which mesh with the teeth of the rack.

[0007] Preferably, a limiting strip is fixedly connected to the inner wall of the outer shell, and a sliding groove is provided on one side of the rack, with one side of the limiting strip slidably connected to the inner wall of the sliding groove.

[0008] Preferably, a second motor is fixedly connected to the inner wall of the housing, a second rotating shaft is fixedly connected to the output end of the second motor, and a first cam is fixedly connected to the surface of the second rotating shaft.

[0009] Preferably, the inner cavity of the housing is rotatably connected to a third rotating shaft, the surface of the third rotating shaft is fixedly connected to a second cam, and the surface of the third rotating shaft and the surface of the second rotating shaft are connected by a transmission belt.

[0010] Preferably, a fixed shaft is fixedly connected to the inner wall of the discharge port, and a sealing plate is rotatably connected to the surface of the fixed shaft, with one side of the sealing plate abutting against the inner wall of the discharge port.

[0011] Preferably, a clamp is fixedly connected to the surface of the first rotating shaft, and one side of the clamp engages with one side of the sealing plate.

[0012] The advantages of this utility model are: This invention utilizes a material distribution mechanism. Workers pour crystals into the device through the inlet. Due to gravity, the crystals first fall onto the surface of the first sieve plate, where larger crystals are retained. Other crystals continue to fall onto the second sieve plate, where larger crystals are also retained. Smaller crystals then fall to the bottom of the inner cavity of the outer casing. Subsequently, the rack moves downwards. Because the teeth of the rack mesh with the teeth of the first and second gears, the first and second gears are driven to rotate by the rack. This, in turn, drives the first rotating shaft fixedly connected to it. The second gear drives the second rotating shaft fixedly connected to it, causing the first rotating shaft to rotate the first screen plate fixedly connected to it, and the second rotating shaft to rotate the second screen plate fixedly connected to it. As the angle between the first and second screen plates changes, the grains on their surfaces roll into the corresponding discharge ports due to gravity, thus classifying grains of different sizes and achieving uniformity control. This solves the problems of traditional metal etching devices lacking grain size control functions, resulting in mixed use of grains, and large size differences between the grains used in the metal etching process, leading to a decrease in etching accuracy and surface quality.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a hardware etching uniformity control device based on grain size regulation. (Refer to...) Figures 1 to 3 A hardware etching uniformity control device based on grain size regulation includes a housing 1, an inlet 2 on one side of the housing 1, and a material distribution mechanism 3 in the inner cavity of the housing 1. The material dispensing mechanism 3 includes a first rotating shaft 301, one end of which is rotatably connected to the inner cavity of the outer casing 1. A first screen plate 302 is fixedly connected to the surface of the first rotating shaft 301, and the surface of the first screen plate 302 is rotatably connected to the inner cavity of the outer casing 1. A first gear 303 is fixedly connected to the surface of the first rotating shaft 301. A second rotating shaft 304 is rotatably connected to the inner cavity of the outer casing 1. A second screen plate 305 is fixedly connected to the surface of the second rotating shaft 304, and a second gear 306 is fixedly connected to the surface of the second rotating shaft 304. A rack 30 is slidably connected to the inner cavity of the outer casing 1. 7. The teeth of rack 307 mesh with the teeth of the first gear 303, and the teeth of rack 307 mesh with the teeth of the second gear 306. A discharge port 308 is provided on one side of the outer casing 1. A transmission mechanism 4 is provided inside the outer casing 1. A material distribution mechanism 3 is provided. Screens are provided on the first screen plate 302 and the second screen plate 305, allowing the first screen plate 302 and the second screen plate 305 to screen the crystals. The aperture of the first screen plate 302 is larger than that of the second screen plate 305, so the size of the crystals passing through the first screen plate 302 is larger than that passing through the second screen plate 305. The worker pours the crystals into the device through the feed inlet 2. Due to gravity, the crystals first fall onto the surface of the first sieve plate 302, where larger crystals are retained. Other crystals continue to fall onto the second sieve plate 305, where larger crystals are retained. Smaller crystals then fall to the bottom of the inner cavity of the outer shell 1. Subsequently, the rack 307 moves downward. Since the teeth of the rack 307 mesh with the teeth of the first gear 303 and the second gear 306, the first gear 303 and... The second gear 306 is driven to rotate by the rack 307, thereby driving the first gear 303 to drive the first rotating shaft 301 fixedly connected to it, and the second gear 306 to drive the second rotating shaft 304 fixedly connected to it. This causes the first rotating shaft 301 to drive the first screen plate 302 fixedly connected to it to rotate, and the second rotating shaft 304 to drive the second screen plate 305 fixedly connected to it to rotate. As the angle between the first screen plate 302 and the second screen plate 305 changes, the grains on their surfaces roll into the corresponding discharge port 308 due to gravity, thus classifying grains of different sizes and achieving uniformity control.

[0018] Reference Figure 3The transmission mechanism 4 includes a first motor 401, one side of which is fixedly connected to the inner wall of the outer casing 1. The output end of the first motor 401 is fixedly connected to a first rotating shaft 402, and one end of the first rotating shaft 402 is fixedly connected to a third gear 403. The teeth of the third gear 403 mesh with the teeth of the rack 307. By setting the transmission mechanism 4, the first motor 401 works and controls the first rotating shaft 402 fixedly connected to its output end to rotate. As a result, the first rotating shaft 402 drives the third gear 403 fixedly connected to it to rotate. Since the teeth of the third gear 403 mesh with the teeth of the rack 307, the rotation of the third gear 403 drives the rack 307 to move vertically.

[0019] Reference Figure 3 A limiting strip 5 is fixedly connected to the inner wall of the outer shell 1. A groove 6 is provided on one side of the rack 307. One side of the limiting strip 5 is slidably connected to the inner wall of the groove 6. By setting the limiting strip 5 and the groove 6, since one side of the limiting strip 5 is slidably connected to the inner wall of the groove 6 and one side of the limiting strip 5 is fixedly connected to the inner wall of the outer shell 1, the limiting strip 5 can limit the rack 307 with the groove 6, thereby improving its movement stability.

[0020] Reference Figure 4 A second motor 7 is fixedly connected to the inner wall of the outer casing 1. A second rotating shaft 8 is fixedly connected to the output end of the second motor 7. A first cam 9 is fixedly connected to the surface of the second rotating shaft 8. By setting the second motor 7, the second motor 7 works and controls the second rotating shaft 8 fixedly connected to its output end. Thus, the second rotating shaft 8 drives the first cam 9 fixedly connected to it. During the rotation, the protruding end of the first cam 9 can periodically strike the first sieve plate 302. By striking the first sieve plate 302, the first sieve plate 302 vibrates, thereby causing the crystals on the surface of the first sieve plate 302 to jump, thus improving the screening ability of the first sieve plate 302.

[0021] Reference Figure 4 The inner cavity of the outer shell 1 is rotatably connected to a third rotating shaft 10. A second cam 11 is fixedly connected to the surface of the third rotating shaft 10. A transmission belt 12 is drivingly connected between the surface of the third rotating shaft 10 and the surface of the second rotating shaft 8. By setting the transmission belt 12, the second rotating shaft 8 can drive the third rotating shaft 10 to rotate through the transmission belt 12. Thus, the third rotating shaft 10 drives the second cam 11 fixedly connected to it to rotate. During the rotation, the protruding end of the second cam 11 can periodically strike the second sieve plate 305. By striking the second sieve plate 305, the second sieve plate 305 vibrates, thereby causing the crystals on the surface of the second sieve plate 305 to jump, improving the screening capacity of the second sieve plate 305.

[0022] Reference Figure 5A fixed shaft 13 is fixedly connected to the inner wall of the discharge port 308. A sealing plate 14 is rotatably connected to the surface of the fixed shaft 13. One side of the sealing plate 14 is attached to the inner wall of the discharge port 308. By setting the sealing plate 14, the sealing plate 14 naturally droops due to gravity in the normal state. When it is fixed by the clamp 15, it seals the inner cavity of the outer shell 1 to prevent crystals from leaking into the discharge port 308 before the screening is completed.

[0023] Reference Figure 5 A clamp 15 is fixedly connected to the surface of the first rotating shaft 301. One side of the clamp 15 is engaged with one side of the sealing plate 14. By setting the clamp 15, as the dispensing mechanism 3 works, the first rotating shaft 301 rotates, causing the clamp 15 fixedly connected to its surface to move, so that the clamp 15 is disengaged from the sealing plate 14, allowing the sealing plate 14 to move. The sealing plate 14 moves under the push of the grains, thereby releasing the seal on the discharge port 308.

[0024] Working principle: The operator pours the crystals into the device through the feed port 2. Due to gravity, the crystals first fall onto the surface of the first sieve plate 302, where larger crystals are retained. Other crystals continue to fall onto the second sieve plate 305, where larger crystals are retained. Smaller crystals then fall to the bottom of the inner cavity of the outer shell 1. The second motor 7 operates, controlling the second rotating shaft 8 fixedly connected to its output end. The second rotating shaft 8 then drives the first cam 9 fixedly connected to it, causing the first cam 9 to... During rotation, the protruding end of cam 9 periodically strikes the first sieve plate 302, causing it to vibrate and thus agitate the grains on its surface, improving the screening capacity of the first sieve plate 302. Simultaneously, the second rotating shaft 8 drives the third rotating shaft 10 via the transmission belt 12, which in turn drives the second cam 11, which is fixedly connected to it, to rotate. During rotation, the protruding end of the second cam 11 periodically strikes the second sieve plate 305, further agitating the grains on its surface and improving the screening capacity of the first sieve plate 302. The vibration of the second sieve plate 305 causes the crystals on its surface to agitate, improving its screening capacity. Once screening is complete, the first motor 401 operates, controlling the rotation of the first rotating shaft 402 fixedly connected to its output end. This, in turn, drives the third gear 403 fixedly connected to it to rotate. Because the teeth of the third gear 403 mesh with the teeth of the rack 307, the rotation of the third gear 403 causes the rack 307 to move vertically. Since the teeth of the rack 307 mesh with the teeth of the first gear 303 and the second gear 306, the first gear... The first gear 303 and the second gear 306 are driven to rotate by the rack 307. Thus, the first gear 303 drives the first rotating shaft 301 fixedly connected to it, and the second gear 306 drives the second rotating shaft 304 fixedly connected to it. The first rotating shaft 301 drives the first screen plate 302 fixedly connected to it to rotate, and the second rotating shaft 304 drives the second screen plate 305 fixedly connected to it to rotate. As the angle of the first screen plate 302 and the second screen plate 305 changes, the grains on their surfaces roll into the corresponding discharge port 308 due to gravity, so as to classify the grains of different sizes and achieve uniformity control.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
