Description

Technical Field

[0001] This invention relates to the field of electroplating copper additive preparation technology, and more specifically, to a rapid preparation device for the production of chemical copper plating additives. Background Technology

[0002] Additives for electroless copper plating are key auxiliary materials in the electroless copper plating process, and their performance directly affects the quality indicators of the plating layer, such as adhesion, gloss, and uniformity. Electroless copper plating additives are usually formulated by mixing and preparing multiple components in specific proportions.

[0003] Currently, the raw material supply in the preparation of chemical copper plating agents largely relies on manual addition. Manual addition not only lacks precise quantitative control, easily leading to significant deviations in the raw material ratio and affecting product performance, but it is also inefficient. Furthermore, the powdered additives cannot be pre-mixed before being added to the electroplating bath, resulting in localized areas of excessively high or low additive concentrations, which negatively impacts the copper plating effect. Therefore, a rapid preparation device for the production of chemical copper plating additives is urgently needed to solve these problems. Summary of the Invention

[0004] In view of the problems in related technologies, the present invention proposes a rapid modulation device for the production of chemical copper plating additives, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] The technical solution of this invention is implemented as follows:

[0006] A rapid preparation device for producing chemical copper plating additives includes a tank fixedly connected to the top of a support platform. Three raw material cylinders containing different types of additive powders are fixedly connected to the top outer wall of the tank. A sealing plug for ensuring the dryness of the internal material is inserted into the top of each raw material cylinder.

[0007] The tank is equipped with a feeding assembly for quantitatively adding powder to the inside of the raw material cylinder.

[0008] A lifting component for adjusting the amount of powder being fed is provided on one side of the feeding component.

[0009] An inlet pipe is fixedly connected to the outer circumference of the tank, and a drain pipe is fixedly connected to the bottom of the tank. The outer circumference of the tank is provided with scale markings for real-time monitoring of the amount of liquid added. The prepared additive solution is transported to the interior of the electroplating tank through the drain pipe and hose.

[0010] Preferably, the feeding assembly includes a circular baffle disposed inside the tank body. A guide pipe is fixedly connected to the bottom outer wall of the circular baffle. A discharge pipe is fixedly connected to the bottom of each of the three raw material cylinders. The discharge pipe and the guide pipe have the same specifications. A conveying pipe is inserted into the bottom end of the guide pipe. A rotating seat is fixedly connected to the circumferential outer wall of the conveying pipe. A rotating shaft is rotatably connected to the inner walls of both sides of the rotating seat. A rotating roller is fixedly connected to one end of the rotating shaft. A cover plate for sealing the bottom of the conveying pipe is fixedly connected to the circumferential outer wall of the rotating roller. A partition is fixedly connected to the circumferential inner wall of the tank body. A through groove is opened at the top of the partition. A guide cover is fixedly connected to the top of the through groove. The guide cover is located directly below one of the conveying pipes. A rotating plate is fixedly connected to the top of the conveying pipe. A fixed circular plate is disposed inside the tank body. A rotating groove is opened on the circumferential outer wall of the fixed circular plate. The rotating plate is rotatably connected to the rotating groove. A drive assembly for providing power to the feeding assembly is disposed inside the tank body.

[0011] Preferably, the three feed pipes located at the bottom of the three raw material cylinders are in different positions, and the three feed pipes are distributed horizontally at equal distances at the bottom of the three raw material cylinders.

[0012] Preferably, a housing is fixedly connected to the outer circumferential wall of the conveying pipe, and a rotating column is fixedly connected to one end of another rotating shaft. A worm gear is fixedly connected to the outer circumferential wall of the rotating column, and a worm is meshed with the outer circumferential wall of the worm gear. A fourth rotating rod is fixedly connected to the inner circumferential wall of the worm. Both ends of the fourth rotating rod are rotatably connected to the inner walls of the two sides of the housing. A third gear disk is fixedly connected to the outer circumferential wall of the fourth rotating rod. A second gear ring is meshed with the outer circumferential wall of the third gear disk. A first gear ring is meshed with the other side of the second gear ring. A third rotating rod and a second rotating rod are fixedly connected to the inner circumferential walls of the second gear ring and the first gear ring, respectively. Both the third rotating rod and the second rotating rod are rotatably connected to the housing. A second gear disk is fixedly connected to one end of the second rotating rod that extends outside the housing.

[0013] Preferably, a spring is fixedly connected to one side of the outer wall of the cover plate to ensure tight closure, and the end of the spring away from the cover plate is fixedly connected to one side of the outer wall of the housing.

[0014] Preferably, the drive assembly includes a first motor fixedly connected to the outer circumference of the tank body, a first helical gear fixedly connected to the output end of the first motor, a second helical gear meshing with the outer circumference of the first helical gear, a fifth rotating rod fixedly connected to the inner circumference of the second helical gear, a missing gear fixedly connected to the outer circumference of the fifth rotating rod, the missing gear having teeth on its outer circumference, the teeth having a circumference of one-sixth of the total circumference of the missing gear, the missing gear meshing with a first gear disk through its teeth, a first rotating rod fixedly connected to the inner circumference of the first gear disk, the top end of the first rotating rod fixedly connected to the bottom outer wall of the circular baffle, and a swing assembly for increasing the unloading speed provided at the bottom of the fixed circular baffle.

[0015] Preferably, the swing assembly includes a swing rack, an opening rack, and a closing rack fixedly connected to the outer wall of the bottom of the fixed circular plate. The cover is driven to open by the meshing between the second gear disk and the opening rack, and the cover is driven to close by the meshing between the second gear disk and the swing rack and the closing rack. The swing rack and the opening rack each have a groove on one side, and the grooves on the swing rack and the opening rack are staggered.

[0016] Preferably, the lifting assembly includes a rotating rod rotatably connected inside the tank body, a fourth gear disk fixedly connected to the outer circumference of the rotating rod, a handle fixedly connected to one end of the rotating rod, a fixed cylinder fixedly connected to the bottom outer wall of the fixed circular plate, the first rotating rod passing through the inside of the fixed cylinder, and equally spaced circular plates fixedly connected to the outer circumference of the fixed cylinder, the fourth gear disk meshing with the equally spaced circular plates.

[0017] Preferably, a connecting plate is fixedly connected to one side of the outer wall of the housing, and the connecting plate is fixedly connected to the circumferential outer wall of the fixed cylinder.

[0018] Preferably, a second motor is fixedly connected to the outer circumference of the tank, and a stirring rod is fixedly connected to the output end of the second motor. Stirring rods distributed in an equidistant circular pattern are fixedly connected to the outer circumference of the stirring rod.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a rapid mixing device for the production of chemical copper plating additives. Through a feeding assembly and a driving assembly, a first motor drives a first helical gear to rotate. A meshing second helical gear drives a fifth rotating rod and a missing gear to rotate. The rotation of the missing gear causes a meshing first gear disc to rotate as well. When the first gear disc rotates, it causes the first rotating rod to drive a circular baffle to rotate. At this time, the guide pipe at the bottom of the circular baffle rotates with it. When the guide pipe rotates to align with the bottom discharge pipe of a raw material cylinder (three discharge pipes are horizontally equidistant for precise alignment and simultaneous aligned discharge), the powder enters the conveying pipe through the guide pipe and fills it, facilitating subsequent quantitative feeding. Simultaneously, during this process, a cover plate allows for the adjustment of the bottom of the conveying pipe. Effective sealing is achieved to prevent material leakage. During the operation of the drive component, the tooth circumference of the missing gear accounts for one-sixth of the total circumference, allowing the missing gear to intermittently mesh with the first gear disc. This intermittent period ensures that the material inside the raw material cylinder has sufficient time to fill the conveying pipe, preventing insufficient material due to incomplete filling during the feeding process. Simultaneously, the rotating plate at the top of the conveying pipe rotates within the rotating groove of the fixed circular plate, ensuring stable connection of the conveying pipe. This intermittent drive method can precisely control the timing of adding different powders, avoiding the mixing ratio confusion caused by adding multiple powders simultaneously. Compared with manual addition, it significantly improves the quantitative accuracy and reduces the impact of raw material ratio deviations on product performance.

[0021] This invention provides a rapid preparation device for the production of chemical copper plating additives. Through a set oscillating mechanism, when the material in the feeding pipe is completed and rotates to directly above the guide hood, the oscillating component starts working. The second gear disk first meshes with the opening rack, driving the first gear ring to rotate via the second rotating rod. The meshing second gear ring drives the third rotating rod and the third gear disk to rotate. The third gear disk drives the fourth rotating rod and the worm gear to rotate. The meshing worm wheel drives the rotating column and the rotating shaft to rotate, causing the rotating roller to open the cover plate to a certain angle. At this time, the spring is in a compressed state, and the powder inside the feeding pipe enters the lower part of the tank through the through-slot opened at the top of the guide hood and the partition. Then, as the circular baffle continues to rotate, the second gear disk meshes with the oscillating rack. Since the oscillating rack is located on the other side of the second gear disk, it can drive the cover plate to rotate in the reverse direction towards the closing direction. Simultaneously, the grooves on the oscillating rack and the opening rack are staggered, allowing the cover plate to reciprocate during the powder unloading process. The changing angles of opening and closing create an intermittent "pushing" and "guiding" effect on the powder in the conveying pipe. On the one hand, each time the cover opens, the powder falls smoothly, and when it closes, it slightly squeezes the residual powder in the pipe, preventing the powder from accumulating on the inner wall of the conveying pipe due to its own stickiness or particle agglomeration, effectively solving the problem of powder blockage. On the other hand, the reciprocating motion shortens the residence time of the powder in the conveying pipe, speeds up the overall feeding speed, and ensures that the powder in the conveying pipe can quickly and completely enter the lower part of the tank, further ensuring the accuracy of the single feeding amount and avoiding deviations between the actual and set ratios due to powder residue. Subsequently, when the second gear plate meshes with the closing rack, it can drive the cover to close completely, and with the spring reset (the spring was previously in a compressed state, and the reset provides a tight closing force for the cover), it ensures that the cover forms an effective seal on the bottom of the conveying pipe, preventing leakage during subsequent rotation of the conveying pipe and preparing for the next precise feeding.

[0022] This invention provides a rapid mixing device for the production of chemical copper plating additives. Through a lifting component, the amount of additive being fed can be adjusted simultaneously. Specifically, by rotating the handle of the lifting component, the rotating rod and the fourth gear disk rotate. The fourth gear disk meshes with the circular plate on the outer wall of the fixed cylinder, causing the fixed cylinder to lift the conveying pipe, changing the docking depth between the guide pipe and the discharge pipe, thereby adjusting the amount of powder passing through at one time to meet different mixing ratio requirements and enhance the applicability of the device.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 A rapid preparation device for producing chemical copper plating additives includes a tank 1 fixedly connected to the top of a support platform 2. Three raw material cylinders 4 containing different types of additive powders are fixedly connected to the top outer wall of the tank 1. A sealing plug 5 for ensuring the dryness of the internal material is inserted into the top of the raw material cylinders 4.

[0038] The tank 1 is equipped with a feeding component for quantitatively adding powder to the inside of the raw material cylinder 4;

[0039] A lifting component for adjusting the amount of powder fed is provided on one side of the feeding component;

[0040] A liquid inlet pipe 8 is fixedly connected to the outer circumference of the tank body 1, and a liquid outlet pipe 12 is fixedly connected to the bottom of the tank body 1. The outer circumference of the tank body 1 is provided with scale marks 11 for real-time monitoring of the amount of liquid added. The prepared additive solution is transported to the interior of the electroplating tank 3 through the liquid outlet pipe 12 and the hose 10. The entire device realizes the precise quantitative addition and feeding amount adjustment of the additive powder, real-time monitoring of the amount of liquid added, and the additive is mixed evenly through pre-stirring. It solves the problems of lack of precise quantitative control, low efficiency and uneven local concentration of additives in traditional manual addition, and improves the accuracy and efficiency of additive preparation and the subsequent copper plating effect.

[0041] Furthermore, the feeding assembly includes a circular baffle 16 disposed inside the tank 1. A guide pipe 14 is fixedly connected to the bottom outer wall of the circular baffle 16. A discharge pipe 13 is fixedly connected to the bottom of each of the three raw material cylinders 4. The discharge pipe 13 has the same specifications as the guide pipe 14. A conveying pipe 15 is inserted into the bottom end of the guide pipe 14. A rotating seat 41 is fixedly connected to the circumferential outer wall of the conveying pipe 15. A rotating shaft 43 is rotatably connected to the inner walls of both sides of the rotating seat 41. A rotating roller 42 is fixedly connected to one end of the rotating shaft 43. A device for adjusting the circumferential outer wall of the rotating roller 42 is fixedly connected to the rotating shaft 43. The bottom of the conveying pipe 15 is sealed with a cover plate 27. A partition plate 17 is fixedly connected to the inner circumference of the tank body 1. A through groove is opened at the top of the partition plate 17. A guide cover 50 is fixedly connected to the top of the through groove. The guide cover 50 is located directly below a conveying pipe 15. A rotating plate 28 is fixedly connected to the top of the conveying pipe 15. A fixed circular plate 18 is provided inside the tank body 1. A rotating groove 30 is opened on the outer circumference of the fixed circular plate 18. The rotating plate 28 is rotatably connected to the rotating groove 30. A drive component for providing power to the feeding component is provided inside the tank body 1.

[0042] Furthermore, the three feed pipes 13 located at the bottom of the three raw material cylinders 4 are in different positions. The three feed pipes 13 are distributed horizontally at equal distances at the bottom of the three raw material cylinders 4. The three feed pipes 13, which are distributed horizontally at equal distances but in different positions, can accurately and orderly connect with the guide pipe 14 inside the tank 1 that rotates with the circular baffle 16. This avoids the situation where multiple feed pipes 13 connect with the guide pipe 14 at the same time, which would cause different types of additive powders to mix. It ensures that only a single type of powder enters the conveying pipe 15 through the guide pipe 14 each time. This provides a structural basis for the subsequent precise control of the addition order and single addition amount of different powders, further ensuring the accuracy of the distribution ratio of each component of the additives and reducing the impact of premature mixing or mismixing of powders on the performance of the additives and the subsequent copper plating effect.

[0043] Furthermore, a housing 25 is fixedly connected to the outer circumferential wall of the conveying pipe 15, and a rotating column 40 is fixedly connected to one end of another rotating shaft 43. A worm gear 39 is fixedly connected to the outer circumferential wall of the rotating column 40, and a worm 37 meshes with the outer circumferential wall of the worm gear 39. A fourth rotating rod 38 is fixedly connected to the inner circumferential wall of the worm 37. Both ends of the fourth rotating rod 38 are rotatably connected to the inner walls of both sides of the housing 25. A third gear disk 36 is fixedly connected to the outer circumferential wall of the fourth rotating rod 38, and a second gear ring 35 meshes with the outer circumferential wall of the third gear disk 36. A first gear ring 33 meshes with the other side of the second gear ring 35. A third rotating rod 34 and a second rotating rod are fixedly connected to the inner circumferential walls of the second gear ring 35 and the first gear ring 33, respectively. 32. The third rotating rod 34 and the second rotating rod 32 are both rotatably connected to the housing 25. The second rotating rod 32 extends to the outside of the housing 25 and is fixedly connected to the second gear disk 31. When the second gear disk 31 rotates, it can drive the first gear ring 33 to rotate through the second rotating rod 32. The meshing second gear ring 35 drives the third rotating rod 34 and the third gear disk 36 to rotate. The third gear disk 36 drives the fourth rotating rod 38 and the worm gear 37 to rotate. The meshing worm wheel 39 drives the rotating column 40 and the rotating shaft 43 to rotate, so that the rotating roller 42 drives the cover plate 27 to open at a certain angle. At this time, the spring 44 is in a compressed state, and the powder inside the conveying pipe 15 enters the lower part of the tank 1 through the guide cover 50 and the through groove opened at the top of the partition plate 17.

[0044] Furthermore, a spring 44 is fixedly connected to one side of the outer wall of the cover plate 27 to ensure its tight closure. The end of the spring 44 away from the cover plate 27 is fixedly connected to one side of the outer wall of the housing 25. The spring 44 can provide a tight closing force for the cover plate 27, ensuring that the cover plate 27 forms an effective seal on the bottom of the conveying pipe 15, preventing material leakage during the subsequent rotation of the conveying pipe 15, and preparing for the next precise feeding.

[0045] Furthermore, the drive assembly includes a first motor 7 fixedly connected to the outer circumference of the tank 1. A first helical gear 47 is fixedly connected to the output end of the first motor 7. A second helical gear 48 meshes with the outer circumference of the first helical gear 47. A fifth rotating rod is fixedly connected to the inner circumference of the second helical gear 48. A missing gear 49 is fixedly connected to the outer circumference of the fifth rotating rod. The outer circumference of the missing gear 49 is provided with teeth, and the circumference of the teeth accounts for one-sixth of the total circumference of the missing gear 49. The missing gear 49 meshes with a first gear disk 24 through its teeth. A first rotating rod 21 is fixedly connected to the inner circumference of the first gear disk 24. The top end of the first rotating rod 21 is fixedly connected to the bottom outer wall of the circular baffle 16. A swing assembly for increasing the unloading speed is provided at the bottom of the fixed circular plate 18. When the first motor 7 is started, the... The first motor 7 drives the first helical gear 47 to rotate, and the meshing second helical gear 48 drives the fifth rotating rod and the missing gear 49 to rotate. The rotation of the missing gear 49 can make the first gear disk 24 meshing with it rotate together. When the first gear disk 24 rotates, it can make the first rotating rod 21 drive the circular baffle 16 to rotate. At this time, the bottom guide pipe 14 of the circular baffle 16 rotates with it. When the guide pipe 14 rotates to align with the bottom discharge pipe 13 of a certain raw material cylinder 4 (the three discharge pipes 13 are distributed horizontally at equal distances, which facilitates precise docking and can realize simultaneous alignment and discharge), the powder enters the conveying pipe 15 through the guide pipe 14 to fill it, which is convenient for the subsequent quantitative feeding needs (it should be noted that the volume ratio inside the three conveying pipes 15 is the same as the rated addition ratio of the three additives to ensure the accuracy of feeding).

[0046] Furthermore, the swing assembly includes a swing rack 51, an opening rack 52, and a closing rack 54 fixedly connected to the bottom outer wall of the fixed circular plate 18. The cover plate 27 can be opened by the meshing between the second gear disk 31 and the opening rack 52, and the cover plate 27 can be closed by the meshing between the second gear disk 31 and the swing rack 51 and the closing rack 54. Grooves 53 are provided on one side of both the swing rack 51 and the opening rack 52, and the grooves 53 on the swing rack 51 and the opening rack 52 are staggered. As the circular baffle 16 continues to rotate, the second gear disk 31 meshes with the swing rack 51. Since the swing rack 51 is located on the other side of the second gear disk 31, it can drive the cover plate 27 to rotate in the closing direction in the opposite direction. Simultaneously, the grooves 53 on the swing rack 51 and the opening rack 52 are staggered. The cover plate 27 can reciprocate by opening and closing at different angles during the powder unloading process, creating an intermittent "pushing" and "guiding" effect on the powder in the conveying pipe 15. On the one hand, each time the cover plate 27 opens, the powder can fall smoothly, and when it closes, it can slightly squeeze the residual powder in the pipe, preventing the powder from accumulating on the inner wall of the conveying pipe 15 due to its own stickiness or particle agglomeration, effectively solving the powder blockage problem. On the other hand, the reciprocating motion shortens the residence time of the powder in the conveying pipe 15, speeds up the overall unloading speed, and ensures that the powder in the conveying pipe 15 can quickly and completely enter the lower part of the tank 1, further ensuring the accuracy of the single feeding amount and avoiding deviations between the actual ratio and the set ratio due to powder residue. Subsequently, when the second gear disk 31 meshes with the closing rack 54, it can drive the cover plate 27 to close completely.

[0047] Furthermore, the lifting assembly includes a rotating rod 45 rotatably connected inside the tank 1. A fourth gear disk 46 is fixedly connected to the outer circumference of the rotating rod 45. A handle 6 is fixedly connected to one end of the rotating rod 45. A fixed cylinder 22 is fixedly connected to the bottom outer wall of the fixed circular plate 18. A first rotating rod 21 passes through the inside of the fixed cylinder 22. Circular plates 23 are fixedly connected to the outer circumference of the fixed cylinder 22 at equal intervals. The fourth gear disk 46 meshes with the circular plates 23 at equal intervals. If the operator needs to adjust the amount of powder fed before feeding, he can rotate the handle 6 of the lifting assembly to drive the rotating rod 45 and the fourth gear disk 46 to rotate. The fourth gear disk 46 meshes with the circular plates 23 on the outer wall of the fixed cylinder 22, causing the fixed cylinder 22 to drive the conveying pipe 15 to rise and fall, changing the docking depth between the guide pipe 14 and the discharge pipe 13, thereby adjusting the amount of powder passed through at one time to meet different mixing ratio requirements and enhance the applicability of the device.

[0048] Furthermore, a connecting plate 26 is fixedly connected to one side of the outer wall of the housing 25. The connecting plate 26 is fixedly connected to the outer circumferential wall of the fixed cylinder 22, ensuring that the housing 25 can stably follow the fixed cylinder 22 in lifting and lowering motion.

[0049] Furthermore, a second motor 9 is fixedly connected to the outer circumference of the tank 1. A stirring rod 19 is fixedly connected to the output end of the second motor 9. Stirring rods 20, which are evenly distributed in a circular pattern, are fixedly connected to the outer circumference of the stirring rod 19. The second motor 9 drives the stirring rod 19 and the stirring rods 20 to rotate, which fully stirs and mixes the powder and liquid in the tank 1 to form a uniform additive solution. Compared with the traditional method of adding directly without pre-stirring, this effectively prevents the local concentration of the additive from being too high or too low after it is added to the electroplating tank 3, thus ensuring the subsequent copper plating effect.

[0050] In summary, with the aid of the above-mentioned technical solution of the present invention, in use, the first motor 7 is first started, which drives the first helical gear 47 to rotate. The meshing second helical gear 48 drives the fifth rotating rod and the missing gear 49 to rotate. The rotation of the missing gear 49 causes the first gear disk 24 meshing with it to rotate together. When the first gear disk 24 rotates, it causes the first rotating rod 21 to drive the circular baffle 16 to rotate. At this time, the bottom guide pipe 14 of the circular baffle 16 rotates with it. When the guide pipe 14 rotates to align with the bottom discharge pipe 13 of a certain raw material cylinder 4 (the three discharge pipes 13 are distributed horizontally at equal distances, which facilitates precise docking and can achieve simultaneous aligned discharge), the powder enters the conveying pipe 15 through the guide pipe 14 to fill it, which facilitates the subsequent quantitative feeding requirements. (It should be noted that the volume ratio inside the three conveying pipes 15 is the same as the rated addition ratio of the three additives to ensure the accuracy of feeding.) Meanwhile, during this process, the cover plate 27 can effectively seal the bottom of the conveying pipe 15 to prevent material leakage. During the operation of the drive component, since the tooth circumference of the missing gear 49 accounts for one-sixth of the total circumference, the missing gear 49 can intermittently mesh with the first gear disk 24. During this intermittent period, the material inside the raw material cylinder 4 can effectively ensure that there is enough time to fill the conveying pipe 15, avoiding the situation where the material inside the conveying pipe 15 is not completely filled during the feeding process, resulting in insufficient material quantity. At the same time, the rotating plate 28 at the top of the conveying pipe 15 rotates in the rotating groove 30 of the fixed circular plate 18 to ensure stable connection of the conveying pipe 15. This intermittent drive method can accurately control the timing of adding different powders, avoiding the confusion of the ratio caused by adding multiple powders at the same time. Compared with manual addition, it greatly improves the quantitative accuracy and reduces the impact of raw material ratio deviation on product performance.

[0051] When the material is fed into the conveying pipe 15 and rotates to directly above the guide cover 50, the swing assembly starts to work. The second gear disk 31 first meshes with the opening rack 52, driving the first gear ring 33 to rotate through the second rotating rod 32. The meshing second gear ring 35 drives the third rotating rod 34 and the third gear disk 36 to rotate. The third gear disk 36 drives the fourth rotating rod 38 and the worm gear 37 to rotate. The meshing worm wheel 39 drives the rotating column 40 and the rotating shaft 43 to rotate, causing the rotating roller 42 to drive the cover plate 27 to open at a certain angle. At this time, the spring 4 4 is in a compressed state, while the powder inside the conveying pipe 15 enters the lower part of the tank 1 through the guide cover 50 and the through groove opened at the top of the partition 17. Then, as the circular baffle 16 continues to rotate, the second gear disk 31 will mesh with the swing rack 51. Since the swing rack 51 is set on the other side of the second gear disk 31, it can drive the cover plate 27 to rotate in the closing direction in the opposite direction. At the same time, the grooves 53 opened on the swing rack 51 and the opening rack 52 are staggered, which can make the cover plate 27 reciprocate during the powder unloading process. The changing angles of opening and closing create an intermittent "pushing" and "guiding" effect on the powder within the conveying pipe 15. On one hand, each time the cover 27 opens, it allows the powder to fall smoothly, while closing it slightly squeezes any residual powder inside the pipe, preventing the powder from accumulating on the inner wall of the conveying pipe 15 due to its own stickiness or particle agglomeration, effectively solving the powder blockage problem. On the other hand, the reciprocating motion shortens the residence time of the powder in the conveying pipe 15, accelerating the overall feeding speed and ensuring that the powder in the conveying pipe 15 can quickly and completely enter the tank 1. The lower part further ensures the accuracy of the single feeding amount, avoiding deviation between the actual ratio and the set ratio due to powder residue. Subsequently, when the second gear disk 31 meshes with the closing rack 54, it can drive the cover plate 27 to close completely, and cooperate with the spring 44 to reset (the spring 44 was previously in a compressed state, and can provide a tight closing force for the cover plate 27 when resetting), ensuring that the cover plate 27 forms an effective seal on the bottom of the conveying pipe 15, preventing material leakage during the subsequent rotation of the conveying pipe 15, and preparing for the next accurate feeding.

[0052] Meanwhile, if the staff needs to adjust the amount of powder to be fed before feeding, they can turn the handle 6 of the lifting component to drive the rotating rod 45 and the fourth gear disk 46 to rotate. The fourth gear disk 46 meshes with the circular plate 23 on the outer wall of the fixed cylinder 22, so that the fixed cylinder 22 drives the conveying pipe 15 to rise and fall, changing the docking depth between the guide pipe 14 and the discharge pipe 13, thereby adjusting the amount of powder to be fed at one time to meet different ratio requirements and enhance the applicability of the device. Then, the second motor 9 drives the stirring rod 19 and the stirring rod 20 to rotate, so as to fully stir and mix the powder and liquid in the tank 1 to form a uniform additive solution. Compared with the traditional method of adding directly without pre-stirring, it effectively prevents the local concentration of the additive from being too high or too low after it is added to the electroplating tank 3, ensuring the subsequent copper plating effect. Finally, the prepared additive solution is transported to the electroplating tank 3 through the drain pipe 12 and the hose 10 to complete the entire preparation and transportation process. The whole device realizes the automation, precision and efficiency of additive preparation, greatly improving production efficiency and reducing the intensity of manual operation.
