AI Technical Summary
In existing electroless nickel plating processes, the concentration of the cleaning solution in the cleaning tank is prone to increase, which leads to a decrease in cleaning effect. This requires frequent replacement of the cleaning agent or an increase in the number of cleaning tanks, resulting in a large footprint.
A pure water tank is added between the chemical tank and the cleaning tank to collect the chemical solution dripping from the workpiece for preliminary drainage treatment. The separated chemical solution is then recycled through a recycling unit, reducing the burden on the cleaning tank.
Extending the service life of the cleaning tank slows down the rate at which the concentration of cleaning agents increases, thus saving on cleaning agent costs.

Technical Field
[0001] This utility model belongs to the field of chemical plating technology, specifically an online chemical solution recovery system. Background Technology
[0002] Electroless nickel plating is a process that deposits nickel onto a substrate surface through a chemical reaction. Unlike electroplating, electroless nickel plating does not require an electric current; instead, it relies on a chemical reduction reaction to deposit nickel. This process can uniformly form a nickel layer on various material surfaces, making it particularly suitable for parts with complex shapes or requiring good coverage.
[0003] In existing technologies, the workpiece is often lifted by a hoisting mechanism or fixed to a frame, and then immersed in a chemical solution tank for chemical nickel plating. After the nickel plating is completed, the workpiece is then immersed in a cleaning tank by the hoisting mechanism to remove the residual chemicals. After a period of time, the concentration of chemicals in the cleaning tank will increase, which may even affect the cleaning effect. Therefore, the cleaning agent in the cleaning tank needs to be replaced frequently, or multiple cleaning tanks need to be set up to ensure the cleaning effect of the workpiece. This method will increase the footprint of the entire system.

DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0029] Example 1
[0030] Reference Figs. 1-4 An on-line recovery system of a chemical solution includes a chemical solution pool 1, a pure water pool 2, a cleaning pool 3, and a recovery unit 4. A fixing frame B with a workpiece fixed thereon is driven by an external lifting mechanism A to stay in the chemical solution pool 1, the pure water pool 2, and the cleaning pool 3 in sequence.
[0031] The chemical solution pool 1 is used to provide a chemical environment for the workpiece, so that the workpiece completes plating in the chemical solution pool 1.
[0032] The pure water in the pure water pool 2 has a liquid level lower than the workpiece, and the pure water pool 2 is used to collect the chemical solution dripping from the workpiece.
[0033] The cleaning pool 3 is used to clean the chemical solution remaining on the workpiece.
[0034] The pure water tank 2 is connected with the recovery unit 4, the recovery unit 4 is used for recovering the mixed liquid in the pure water tank 2, and the separated medicine liquid is transported to the medicine liquid tank 1.
[0035] In this design, the operator fixes the workpiece on a fixing frame B, or directly hoists the workpiece through the hoisting mechanism A, and then immerses the workpiece in the medicine liquid tank 1. Implicitly, the medicine liquid tank 1 is also provided with a heating module. The purpose of heating is to promote the occurrence of chemical reaction, improve the nickel plating speed, shorten the nickel plating time, improve the adhesion and compactness of the plating layer, and further improve the performance of the plating layer.
[0036] Until the workpiece is plated, the hoisting mechanism A takes out the workpiece from the medicine liquid tank 1 and moves to the pure water tank 2. The medicine liquid remaining on the workpiece will drip into the pure water tank 2 under the action of gravity. With the passage of time, the concentration of the medicine liquid in the pure water tank 2 will become higher and higher. After the water draining is completed, the workpiece is moved to the cleaning tank 3. At this time, the medicine liquid remaining on the workpiece is much less than that when it is just taken out from the medicine liquid tank 1. In this way, the burden of the cleaning tank 3 is reduced, the speed of increasing the concentration of the medicine liquid in the cleaning tank 3 is slowed down, and the use time of the cleaning tank 3 is prolonged. Another purpose of setting the pure water tank 2 is to make the medicine liquid tank 1 idle during water draining. The workpiece that has not completed nickel plating can be immersed in the medicine liquid tank 1 at this time.
[0037] In addition, the mixed solution in the pure water tank 2 is treated by the recovery unit 4, and the separated medicine liquid is replenished into the medicine liquid tank 1.
[0038] Further, the recovery unit 4 comprises a filtering module 41, an evaporation module 42 and a storage module 43 connected in sequence. The pure water tank 2 is provided with an inlet pipe 23 for replenishing pure water and an outlet pipe 24 connected with the filtering module 41. The storage module 43 is provided with an output pipe 431 connected with the medicine liquid tank 1.
[0039] Specifically, the filtering module 41 can adopt a filter tank for filtering impurities in the mixed solution. The filtered mixed solution enters the evaporation module 42. Since the pure water tank 2 contains pure water, the mixed solution mainly contains a mixture of pure water and medicine liquid. By evaporating the pure water, the medicine liquid can be separated and introduced into the storage module 43. The storage module 43 controls the replenishment amount of the medicine liquid according to the liquid level in the medicine liquid tank 1, realizes recycling and reduces cost.
[0040] Preferably, the inner wall of the pure water tank 2 is provided with symmetrical blowing mechanisms 21. The blowing mechanism 21 comprises a blowing pipe 211 and a plurality of air outlets 212 connected with the blowing pipe 211. The air outlets 212 are inclinedly arranged. The input end of the blowing pipe 211 is connected with an external blowing device.
[0041] In actual use, the air flow is provided by the air supply device to supply the air into the air supply pipe 211 and output from the air outlet 212, so as to promote the dropping of the chemical solution on the workpiece, reduce the draining time and improve the efficiency.
[0042] More preferably, the chemical solution pool 2 is provided with the inclined baffle 22, the number of the baffle 22 is matched with the air blowing mechanism 21, the baffle 22 is located above the air blowing mechanism 21, and the entrance for the workpiece to enter the chemical solution pool 2 is arranged between the baffles 22. The arrangement of the baffle 22 can avoid the chemical solution dropping on the air blowing mechanism 21, and the inclined baffle 22 can also guide the chemical solution dropping on the baffle 22 into the chemical solution pool 2.
[0043] In the embodiment, the chemical solution pool 1 is provided with the first input port 11 connected with the output pipe 431, the second input port 12 connected with the external chemical solution conveying device, and the first liquid discharge pipe 13 for discharging the chemical solution in the chemical solution pool 1.
[0044] Specifically, the chemical solution in the chemical solution pool 1 can be supplemented by the output pipe 431 of the storage module 43 or the external chemical solution conveying device.
[0045] Preferably, the aeration module 33 is arranged in the cleaning pool 3, the third input port 31 for inputting water is arranged on the cleaning pool 3, and the second liquid discharge pipe 32 connected with the filter module 41 is arranged on the cleaning pool 3. In the embodiment, the cleaning liquid in the cleaning pool 3 is preferably water. By arranging the aeration module 33 in the cleaning pool 3, the generation and rising of the bubbles during the aeration process can drive the cleaning liquid to flow, thereby increasing the movement of the liquid. The flowing cleaning liquid can more effectively contact and flush the surface of the object, helping to remove the chemical solution remaining on the workpiece.
[0046] Further, the aeration module 33 includes the gas supply pipe 331 connected with the external gas conveying device and the plurality of gas outlets 332 arranged on the gas supply pipe 331. In the embodiment, the external gas conveying device is preferably a nitrogen gas conveying device, because nitrogen is an inert gas and can avoid some unnecessary chemical reactions.
[0047] Preferably, the cleaning pool 3 is two. Of course, the operator can set three, four or five according to the actual situation, and the number of the cleaning pool 3 is not limited in the embodiment.

In actual use, the fixed frame B can be placed on the notch 51 of the fixed part 5, and the lifting mechanism A does not need to be in a state of load all the time, thereby improving the service life of the machine and reducing energy consumption.
[0049] The above only describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the principles of the present application, a number of improvements or modifications can be made, and these improvements or modifications should be considered as the protection scope of the present application.
