Description

Technical Field

[0001] This utility model relates to the field of tungsten wire processing technology, and in particular to a device for surface treatment of tungsten filaments. Background Technology

[0002] Tungsten filaments are extremely fine filamentary materials made of tungsten metal. Tungsten is a metal with a high melting point, high strength, and high hardness, and it has good electrical and thermal conductivity and corrosion resistance. Tungsten filaments are usually made by drawing tungsten metal into very fine filaments through special processing techniques. Their diameter can be as small as a few micrometers or even smaller. Due to their advantages, tungsten filaments have been widely used in many fields such as electronics, lighting, and aerospace.

[0003] The surface quality of tungsten filaments has a crucial impact on their performance and service life during processing and production. Therefore, surface treatment equipment is needed to process the surface of tungsten filaments in order to improve their service life.

[0004] Currently available tungsten filament surface treatment devices on the market immerse all the tungsten filaments in the treatment solution during the cleaning and coating process. However, due to differences in concentration and temperature within the treatment solution, the substances in the solution flow slowly, making it difficult to ensure that each tungsten filament receives uniform treatment. This affects the processing quality of the product and fails to meet the user's needs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tungsten wire surface treatment device, which aims to improve the problem of uneven workpiece treatment that occurs when using existing tungsten wire surface treatment devices.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a tungsten filament surface treatment device, comprising a treatment frame, a U-shaped plate at the top of the treatment frame, a servo motor fixedly connected to the top of the U-shaped plate, the output end of the servo motor passing through the U-shaped plate and fixedly connected to a cylindrical half-gear, a T-shaped groove at the bottom of the U-shaped plate, a T-shaped block slidably connected inside the T-shaped groove, a rack fixedly connected to the bottom of the T-shaped block, the rack meshing with the cylindrical half-gear, a connecting rod fixedly connected to the bottom of the rack, a hollow rod slidably connected to the outside of the connecting rod, a filter frame fixedly connected to the bottom end of the hollow rod, and an air filter fixedly connected to the left side of the treatment frame. The pump has an air outlet pipe at one end, which passes through the processing frame and is rotatably connected to a connecting pipe. The top of the connecting pipe is connected to a hollow box. Multiple aeration pipes are equidistantly connected to the outer perimeter of the hollow box. Multiple aeration holes are equidistantly connected to the top of each aeration pipe. A hollow ring is rotatably connected to the inner center of the connecting pipe. Multiple support rods are fixedly connected to the inner perimeter of the hollow ring at equal intervals. One end of each support rod is fixedly connected to the same fixed column. An impeller is fixedly connected to the bottom of the fixed column. An anti-clogging mechanism is provided inside the processing frame to prevent the filter frame from being clogged by impurities, thus affecting the normal operation of subsequent processing.

[0007] As a further description of the above technical solution: The anti-clogging mechanism includes a servo motor, which is fixedly connected to the front left side of the processing frame. The output end of the servo motor passes through the processing frame and is fixedly connected to a first rotating rod. The right end of the first rotating rod is fixedly connected to a drive gear. The left side inside the processing frame is rotatably connected to a second rotating rod. The right end of the second rotating rod is fixedly connected to a driven half gear, which meshes with the drive gear. A fixing rod is fixedly connected to the rear side of the driven half gear.

[0008] As a further description of the above technical solution: A one-way valve is connected to the bottom right side of the processing frame, and a water outlet pipe is provided on the middle outer side of the one-way valve.

[0009] As a further description of the above technical solution: The left and right sides of the U-shaped plate are threaded with second bolts, one end of which passes through the U-shaped plate and the processing frame in sequence.

[0010] As a further description of the above technical solution: The processing frame has an observation window at its front end and a scale on the right side of its front end.

[0011] As a further description of the above technical solution: A control panel is fixedly connected to the front left side of the processing frame. The control panel is electrically connected to the servo motor, the servo motor, and the air pump.

[0012] As a further description of the above technical solution: The hollow rod has a threaded connection to the right side with a first bolt, and the left end of the first bolt passes through the hollow rod and the connecting rod in sequence.

[0013] As a further description of the above technical solution: One end of the air pump is connected to an air inlet pipe, and the size of the T-block matches the internal size of the T-slot.

[0014] This utility model has the following beneficial effects: In this invention, an air pump injects outside air into the connecting pipe. The impeller in the connecting pipe rotates due to the fluid flow, causing the connecting pipe to rotate. The hollow box then rotates the aeration pipe. Simultaneously, a servo motor drives the cylindrical half-gear to rotate, and the rack causes the filter screen frame to sway left and right. This further promotes the flow of the treatment liquid, ensuring full contact between the treatment liquid and the tungsten filaments. This ensures that each tungsten filament is treated uniformly, thus not affecting the product's processing quality and meeting the user's needs.

[0015] In this invention, a servo motor drives the first rotating rod to rotate, and the driving gear on the outside of the first rotating rod will rotate accordingly. The driven half gear meshing with it will rotate up and down, thereby driving the fixed rod to move up and down to knock on the bottom of the filter screen frame. This can prevent impurities on the surface of the tungsten filament from clogging the filter screen frame and affecting the subsequent processing of the tungsten filament, thus improving the practicality of the device.

[0018] 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 protection scope of the present utility model.

[0019] Reference Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a tungsten filament surface treatment device, comprising a treatment frame 1, a U-shaped plate 3 at the top of the treatment frame 1, a servo motor 4 fixedly connected to the top of the U-shaped plate 3, the output end of the servo motor 4 passing through the U-shaped plate 3 and fixedly connected to a cylindrical half-gear 5, a T-shaped groove 6 at the bottom of the U-shaped plate 3, a T-shaped block 7 slidably connected inside the T-shaped groove 6, a rack 8 fixedly connected to the bottom of the T-shaped block 7, the rack 8 meshing with the cylindrical half-gear 5, a connecting rod 9 fixedly connected to the bottom of the rack 8, a hollow rod 10 slidably connected to the outside of the connecting rod 9, a filter frame 11 fixedly connected to the bottom end of the hollow rod 10, an air pump 12 fixedly connected to the left side of the treatment frame 1, one end of the air pump 12 connected to an air outlet pipe 14, and one end of the air outlet pipe 14 passing through the treatment frame 1. A connecting pipe 15 is rotatably connected to the filter screen 11. The top of the connecting pipe 15 is connected to a hollow box 20. Multiple aeration pipes 21 are equidistantly connected to the outer periphery of the hollow box 20. Multiple aeration holes 22 are equidistantly connected to the top of each aeration pipe 21. A hollow ring 16 is rotatably connected to the middle of the inner side of the connecting pipe 15. Multiple support rods 17 are equidistantly fixed to the inner periphery of the hollow ring 16. One end of each support rod 17 is fixedly connected to the same fixed column 18. An impeller 19 is fixedly connected to the bottom end of the fixed column 18. An anti-clogging mechanism 2 is provided inside the processing frame 1. The anti-clogging mechanism 2 is used to prevent the filter screen frame 11 from being blocked by impurities, which would affect the normal operation of subsequent processing. One end of the air pump 12 is connected to an air inlet pipe 13. The size of the T-shaped block 7 matches the internal size of the T-shaped groove 6. Specifically, air pump 12 injects outside air into connecting pipe 15. When air enters connecting pipe 15, impeller 19 inside will start to rotate due to the influence of the fluid. This rotation not only drives connecting pipe 15 itself to rotate, but also drives hollow box 20 to rotate. The rotation of hollow box 20 will drive aeration pipe 21 to rotate accordingly. At the same time, servo motor 4 drives cylindrical half gear 5 to rotate. The rack 8 meshing with cylindrical half gear 5 will move left and right accordingly. At this time, the movement of rack 8 will drive T-block 7 to slide left and right in T-groove 6. The filter screen frame 11 at the bottom of T-block 7 will also shake accordingly with the left and right movement of T-block 7. This shaking can effectively prevent the tungsten wires in filter screen frame 11 from accumulating together, thereby avoiding the impact of tungsten wire accumulation on the treatment effect. In this way, the flow of treatment liquid can be further promoted, ensuring that the treatment liquid can fully contact each tungsten wire, and each tungsten wire can be treated uniformly, thus not affecting the processing quality of the product.

[0020] Reference Figure 4The anti-blocking mechanism 2 includes a servo motor 201, which is fixedly connected to the left front end of the processing frame 1. The output end of the servo motor 201 passes through the processing frame 1 and is fixedly connected to a first rotating rod 202. The right end of the first rotating rod 202 is fixedly connected to a drive gear 203. The left side inside the processing frame 1 is rotatably connected to a second rotating rod 204. The right end of the second rotating rod 204 is fixedly connected to a driven half gear 205. The driven half gear 205 meshes with the drive gear 203. The rear side of the driven half gear 205 is fixedly connected to a fixing rod 206. Specifically, the servo motor 201 can drive the first rotating rod 202 to rotate. When the first rotating rod 202 starts to rotate, the drive gear 203 on its outer side will also rotate. At the same time, the driven half gear 205, which is tightly meshed with the drive gear 203, will be driven accordingly and thus generate up-and-down reciprocating motion. This up-and-down reciprocating motion can be further transmitted to the fixed rod 206 to make it move up and down. The up-and-down movement of the fixed rod 206 can knock the bottom of the filter screen frame 11. This action can remove impurities that may accumulate at the bottom of the filter screen frame 11. In this way, impurities on the surface of the tungsten wire can be effectively prevented from clogging the filter screen frame 11, thereby ensuring that the processing of the tungsten wire can proceed smoothly.

[0021] Reference Figure 1 and Figure 2 A one-way valve 25 is connected to the bottom right side of the processing frame 1. A water outlet pipe 26 is provided in the middle of the outer side of the one-way valve 25. An observation window 27 is provided at the front end of the processing frame 1. A scale 28 is provided on the right side of the front end of the processing frame 1. Specifically, the water outlet pipe 26 facilitates the discharge of the treatment liquid in the treatment box 1, while the one-way valve 25 prevents liquid leakage in the treatment box 1. The cooperation between the observation window 27 and the scale 28 allows staff to easily obtain the liquid level inside the treatment box 1 at any time.

[0022] Reference Figure 1 and Figure 2 The left and right sides of the U-shaped plate 3 are threaded with second bolts 24. One end of the second bolt 24 passes through the U-shaped plate 3 and the processing frame 1 in sequence. The right side of the hollow rod 10 is threaded with a first bolt 23. The left end of the first bolt 23 passes through the hollow rod 10 and the connecting rod 9 in sequence. Specifically, loosening the second bolt 24 can release the limiting fixation of the U-shaped plate 3, while loosening the first bolt 23 can release the limiting fixation of the filter screen frame 11, at which point the processed tungsten wire can be taken out.

[0023] Reference Figure 1 and Figure 4A control panel 29 is fixedly connected to the front left side of the processing frame 1. The control panel 29 is electrically connected to the servo motor 201, the servo motor 4 and the air pump 12 respectively. Specifically, the operation of the servo motor 201, servo motor 4 and air pump 12 can be controlled through the control panel 29. The model of the servo motor 201 is A5II, the model of the servo motor 4 is MHMF042L1U2MMBDLN25, and the model of the air pump 12 is WP27D-24D.

[0024] Working principle: When using this device, first inject the treatment liquid into the treatment frame 1, then put the tungsten wire to be treated into the filter frame 11. Then, the air pump 12 can inject outside air into the connecting pipe 15. At this time, the impeller 19 in the connecting pipe 15 will rotate due to the influence of the fluid, thereby driving the connecting pipe 15 to rotate. The hollow box 20 will drive the aeration pipe 21 to rotate. At the same time, the servo motor 4 can drive the cylindrical half gear 5 to rotate. The rack 8 that meshes with it will drive the T-block 7 to move left and right in the T-groove 6. The filter frame 11 at the bottom of the T-block 7 will sway left and right, which can prevent the tungsten wire in the filter frame 11 from accumulating together and affecting its treatment effect. In this way, the flow of the treatment liquid can be further promoted, so that the treatment liquid and the tungsten wire can be fully contacted. While the tungsten filament processing is underway, the servo motor 201 is activated. The servo motor 201 drives the first rotating rod 202 to rotate, and the drive gear 203 on the outside of the first rotating rod 202 rotates accordingly. The driven half gear 205 meshing with it rotates up and down, thereby driving the fixed rod 206 to move up and down to knock on the bottom of the filter screen frame 11. This prevents impurities on the surface of the tungsten filament from clogging the filter screen frame 11 and affecting the subsequent tungsten filament processing. After the processing is completed, the one-way valve 25 is opened, and the processing liquid in the processing frame 1 is discharged through the outlet pipe 26. Loosening the second bolt 24 releases the limiting fixation of the filter screen frame 11, and then the processed tungsten filament can be taken out.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
