Description

Technical Field

[0001] The invention belongs to the technical field of electroplating equipment, and in particular refers to a self-adaptive adding device for electroplating reagents. Background Art

[0002] Electroplating is an electrochemical and redox process. The metal workpiece is used as the cathode and placed in the electroplating solution together with a metal plate anode of a specific material. After direct current is passed, the metal ions will adhere to the surface of the workpiece to form an electroplated layer.

[0003] When external conditions such as current and temperature remain stable, the ions in the plating solution will be continuously consumed, and changes in ion concentration will also affect the consistency of the electroplated layer; therefore, in the process of continuous electroplating, if the metal ions can be continuously replenished according to the consumption, thereby compensating for the ion concentration and maintaining it in a relatively stable state, the quality and consistency of the electroplating process will be better maintained.

[0004] When the workpiece is taken out of the liquid, some liquid will also adhere to the surface of the coating. Therefore, during the continuous electroplating process, not only the ions will be consumed, but the total amount of liquid will also be consumed. Therefore, continuously replenishing the appropriate concentration of reagents during this process will be more conducive to maintaining the total amount and concentration of the electroplating solution stable. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes an adaptive adding device for electroplating agents with an ingenious structure, which can adaptively control the replenishment amount of the agent according to the immersion duration of the workpiece. This scheme creatively proposes a self-resetting electroplating sensing mechanism and an adaptive dosing stirring mechanism, and utilizes the objective law related to the consumption of ions and the duration of electroplating. During the continuous rotation of the electroplating bracket, the replenishment speed of the agent required for electroplating is adaptively controlled by sensing the duration of the electroplating process.

[0006] In this technical solution, since the sliding direction of the sensing piston in the sliding sensing cavity is the same as the direction in which the sliding sensing cavity itself can slide freely, how to ensure that the sensing lever and the hook plate portion can be stably combined and separated is another problem faced in the actual operation of the present invention. In order to solve this problem, the present invention provides an elastic rope that can be stretched and a hook plate return spring that can be compressed, so that the movement of the sensing lever on the hook plate portion will first be converted into the movement of the sensing piston, and the sliding sensing cavity will be pushed to slide as a whole only after the sensing piston slides a certain amplitude; and through the smooth groove portion provided at the tail of the arc-shaped slide groove, the sliding sensing cavity can be slightly offset and turned when it slides to the end, so that the sensing lever and the hook plate portion can be separated smoothly.

[0007] The present invention utilizes the rotational motion of the stirring impeller, and uses the driving force of stirring as the driving force for drug feeding without pressurizing the concentrated medicine storage tank and the medicine tube holder, and then controls the opening and closing of the drug feeding valve according to the rotation angle of the rotating holder, thereby achieving the technical effect of adaptively replenishing the medicine.

[0042] like Figure 1 to Figure 13 As shown, the present invention proposes an adaptive adding device for electroplating reagents, comprising an electroplating reaction box 1, a rotating picking mechanism 2, a self-resetting electroplating induction mechanism 3, an adaptive adding and stirring mechanism 4 and a loading and unloading assembly 5, wherein the rotating picking mechanism 2 is arranged on the electroplating reaction box 1, the self-resetting electroplating induction mechanism 3 is arranged on the inner wall of the electroplating reaction box 1, the adaptive adding and stirring mechanism 4 is rotatably arranged at the bottom of the electroplating reaction box 1, and the loading and unloading assemblies 5 are symmetrically arranged on both sides of the electroplating reaction box 1.

[0043] This solution can provide feedback on the actual duration of the electroplating process by sensing the rotation angle of the rotating bracket 11 while the rotating picking mechanism 2 is continuously rotating with the workpiece, and can continuously replenish the concentrated solution during the consumption of metal ions, thereby alleviating the problem of concentration reduction caused by ion consumption, thereby maintaining the solution concentration within a relatively stable range, and achieving the technical effect of improving the quality and consistency of the electroplating process.

[0046] By following the position of the sensing lever 6 that rotates with the rotating bracket 11, the current angle of the continuously rotating rotating spindle 10 and the rotating bracket 11 can be sensed, thereby determining whether the current state is the actual working time of the electroplating process.

[0048] The continuously moving loading and unloading belt 48 can cooperate with the rotating rotating bracket 11 to achieve the effect of automatically picking up and releasing the workpiece, thereby realizing the automation of the electroplating process.

[0049] The adaptive drug adding and stirring mechanism 4 includes a rotating stirring component 28, a spiral drug supply component 29, an adaptive control component 30 and a drug supply component 31. The rotating stirring component 28 is rotatably arranged at the bottom of the electroplating reaction box 1, the spiral drug supply component 29 is located in the rotating stirring component 28, the adaptive control component 30 is arranged at the top of the rotating stirring component 28, and the drug supply component 31 is arranged at the bottom of the rotating stirring component 28.

The stirring impeller 34 is located inside the electroplating reaction box 1.

[0051] The hollow shaft 32 is continuously rotated by the stirring driving gear 33. During this process, the continuous rotation of the medicine feeding auger 36 can ensure that the medicine in the concentrated medicine storage tank 42 always has a tendency to flow into the electroplating reaction box 1, thereby achieving the technical effect of continuous medicine supply by utilizing the driving force of the stirring process without any independent driving device.

[0052] The spiral medicine supply assembly 29 includes an auger support frame 35, a medicine feeding auger 36 and a square sliding bracket 37. The auger support frame 35 is fixedly connected to the hollow rotating shaft 32. There is a hollow portion in the middle of the auger support frame 35 to allow liquid to flow.

[0053] The adaptive control component 30 includes a fixed valve flap 38, a sliding valve flap 39, a rotating sensing chamber 40 and a telescopic valve flap control rod 41. The fixed valve flap 38 is fixedly connected to the hollow rotating shaft 32 and the square sliding bracket 37. The sliding valve flap 39 is slidably arranged in the square sliding bracket 37. The fixed valve flap 38 and the sliding valve flap 39 are arrayed with grids that allow liquid to pass through. When the grids of the fixed valve flap 38 and the sliding valve flap 39 overlap, the liquid can enter the electroplating reaction box 1 from the hollow rotating shaft 32. The rotating sensing chamber 40 is fixedly connected to the square sliding bracket 37. A second hydraulic joint 45 is provided at the tail of the rotating sensing chamber 40.

[0054] The sliding of the sliding valve flap 39 can be controlled by sliding the telescopic valve flap control rod 41, thereby controlling whether the grid parts of the fixed valve flap 38 and the sliding valve flap 39 overlap. By controlling the sliding manner of the sliding valve flap 39, the opening and closing of the adaptive control component 30 can be switched, thereby achieving the technical effect of "replenishing the reagents accordingly when the electroplating process is actually continuing".

[0055] Since the second hydraulic joint 45 is bent upward, the hose for connecting the first hydraulic joint 19 and the second hydraulic joint 45 will not be entangled during the continuous rotation of the hollow shaft 32.

[0056] The reagent supply assembly 31 includes a concentrated reagent storage tank 42, a reagent tube bracket 43 and an upper reagent tube 44. The concentrated reagent storage tank 42 is fixedly connected to the outer side of the electroplating reaction box 1, the reagent tube bracket 43 is fixedly connected to the bottom of the electroplating reaction box 1, the upper reagent tube 44 is snap-fitted into the reagent tube bracket 43, one end of the upper reagent tube 44 is disposed at the bottom of the concentrated reagent storage tank 42, and the other end of the upper reagent tube 44 is rotatably connected to the bottom of the hollow rotating shaft 32.

[0057] The self-resetting electroplating induction mechanism 3 includes a sliding support component 14 and a compression feedback component 15 . The sliding support component 14 is arranged on the inner wall of the electroplating reaction box 1 , and the compression feedback component 15 is arranged on the sliding support component 14 .

[0058] The sliding support assembly 14 includes an arc-shaped support frame 16, an elastic rope 17 and a sliding sensing cavity 18. The arc-shaped support frame 16 is fixedly connected to the inner wall of the electroplating reaction box 1. The arc-shaped support frame 16 is provided with an arc-shaped slide groove 23. A smooth groove portion 24 is provided at one end of the arc-shaped slide groove 23. One end of the elastic rope 17 is provided on the arc-shaped support frame 16. A circular sliding boss 25 is symmetrically provided on the sliding sensing cavity 18. The circular sliding boss 25 is engaged and slidably provided in the arc-shaped slide groove 23 and the smooth groove portion 24. A vertical mounting plate 26 is provided at the bottom of the sliding sensing cavity 18, and the other end of the elastic rope 17 is provided on the vertical mounting plate 26.

[0059] By means of the sliding sensing cavity 18 that can slide along the arc-shaped slide groove 23, the adaptive control component 30 can be kept in the open state during the duration of the electroplating process by the sliding sensing cavity 18 following the movement of the sensing lever 6; at the tail of the arc-shaped slide groove 23, the direction of the sliding sensing cavity 18 is adjusted by the smooth groove portion 24, so that the sensing lever 6 and the hook plate portion 27 can be separated, thereby avoiding the situation where the self-resetting electroplating sensing mechanism 3 is stuck with the sensing lever 6 after sliding to the extreme position.

[0060] The compression feedback assembly 15 includes a first hydraulic joint 19, a sensing piston 20, a U-shaped sensing plate 21 and a hook plate return spring 22. The first hydraulic joint 19 is arranged at the tail end of the sliding sensing cavity 18. The sensing piston 20 is slidably arranged in the sliding sensing cavity 18. The U-shaped sensing plate 21 is fixed to the sensing piston 20. A hook plate portion 27 is provided at the end of the U-shaped sensing plate 21. The sensing lever 6 can contact and move the hook plate portion 27 during rotation. The hook plate return spring 22 is arranged between the inner wall of the sliding sensing cavity 18 and the sensing piston 20.

[0061] Through the sensing piston 20 and the U-shaped sensing plate 21 that can slide relative to the sliding sensing chamber 18, it is possible to feedback whether the sensing lever 6 has moved the self-resetting electroplating sensing mechanism 3 independently of the sliding of the sliding sensing chamber 18, and during the continuous movement of the sensing lever 6, the compression state of the hook plate reset spring 22 can still be continuously maintained, thereby achieving the technical purpose of keeping the adaptive control component 30 continuously open during the continuous electroplating process.

[0062] When in use, the user first needs to start the external motor to rotate the rotating main shaft 10 through the rotating driving gear 12, and the external motor rotates the hollow rotating shaft 32 through the stirring driving gear 33; at the same time, the loading and unloading assembly 5 also continues to move under the drive of the motor; The rotation speed of the rotating spindle 10 and the rotating bracket 11 matches the movement speed of the loading and unloading belt 48. The picking device on the picking bracket 13 can pick up the workpiece on the loading and unloading belt 48 on one side and immerse it in the electroplating reaction box 1. After the electroplating is completed, the picking device located on the picking bracket 13 will send the workpiece to the loading and unloading belt 48 on the other side, thereby realizing automatic loading and unloading and picking. The picking method of the picking bracket 13 can be magnetic suction, clamping or other suitable methods.

[0063] When the rotating bracket 11 rotates with the workpiece and immerses it in the electroplating liquid, the sensing lever 6 contacts and pushes the hook plate portion 27. In the initial state, the sliding sensing cavity 18 is located at the end of the arc-shaped support frame 16 away from the smooth groove portion 24. When the sensing lever 6 contacts and pushes the hook plate portion 27, since the elastic force of the hook plate return spring 22 is smaller than the elastic force of the elastic rope 17, in the first stage, the sliding sensing cavity 18 remains stationary, and the sensing piston 20 overcomes the elastic force of the hook plate return spring 22 and slides toward the first hydraulic joint 19. In this process, the liquid in the sliding sensing cavity 18 is immersed in the rotating sensing cavity 40 through the hose, thereby pushing the sliding valve flap 39 to slide. Since the sliding direction of the sliding valve flap 39 is perpendicular to the pressure direction of the liquid in the hollow shaft 32, the pressure of the liquid will not hinder the sliding of the sliding valve flap 39, and the pressure required to push the sliding valve flap 39 is relatively small; The sliding valve flap 39 slides a certain distance, and the grille parts on the fixed valve flap 38 and the sliding valve flap 39 overlap.

[0064] As the hollow shaft 32 slowly rotates with the stirring impeller 34, the liquid in the electroplating reaction box 1 can be continuously stirred. On the one hand, it can quickly replenish the ions near the workpiece surface after they are consumed. On the other hand, it can also allow the concentrated solution that has just entered the electroplating reaction box 1 to be quickly and fully mixed with the original liquid in the electroplating reaction box 1.

[0065] During the slow rotation of the hollow shaft 32, the medicine feeding auger 36 will also rotate with it, thereby applying an upward thrust to the liquid in the hollow shaft 32. When the grid parts of the fixed valve flap 38 and the sliding valve flap 39 do not overlap, the liquid in the hollow shaft 32 cannot flow into the electroplating reaction box 1. When the grid parts of the fixed valve flap 38 and the sliding valve flap 39 overlap, the liquid in the hollow shaft 32 will flow into the electroplating reaction box 1, thereby replenishing the consumed medicine in the electroplating reaction box 1.

[0066] When the workpiece is immersed in the electroplating solution, the sensing lever 6 will push the sliding sensing cavity 18 to slide while the hook plate return spring 22 remains compressed. During this process, the reagent in the hollow shaft 32 continues to enter the electroplating reaction box 1 to compensate for the liquid in the electroplating reaction box 1. When the sliding sensing cavity 18 slides along the arc-shaped slide groove 23 to the smooth groove portion 24, the workpiece is just taken out of the electroplating liquid, and the direction of the sliding sensing cavity 18 will be deflected relative to the rotating bracket 11. At this time, the hook plate portion 27 and the sensing lever 6 are separated, and the sensing lever 6 without limiting position continues to rotate with the rotating bracket 11 until the workpiece is transported to another loading and unloading belt 48.

[0067] After the hook plate portion 27 and the sensing lever 6 are separated, the sensing piston 20 is first reset under the elastic force of the hook plate reset spring 22, and the liquid in the rotating sensing chamber 40 enters the sliding sensing chamber 18 through the hose, and the telescopic valve flap control rod 41 also slides and resets with the sliding valve flap 39, and the adaptive control assembly 30 is restored to the closed state; Then, the sliding sensing cavity 18 will slide back to the end away from the smooth groove portion 24 under the elastic force of the elastic rope 17 .

[0068] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0069] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
