Description

Technical Field

[0001] The present application relates to the field of electroplating technology, and in particular to a room temperature evaporation system. Background Art

[0002] Roughening is a very important part of the ABS electroplating process. The quality of roughening will directly affect the bonding force, brightness and integrity of the coating. The roughening process can oxidize and dissolve the spherical rubber on the surface of ABS plastic, so that the surface of the plated part has hydrophilicity, and at the same time, form micropores on the surface of the plated part, thereby ensuring adsorption and adhesion of the coating. The roughening of ABS plastic generally includes three methods: high sulfuric acid type, high chromic acid type and phosphoric acid type. From the perspective of environmental protection, it is advisable to use chromium-free high sulfuric acid type. Its main steps include surface treatment with concentrated sulfuric acid, followed by swelling treatment with a swelling agent, roughening, decontamination treatment, followed by chemical etching with an etching solution, followed by neutralization treatment, and finally activation treatment, thereby obtaining a surface roughening layer of special engineering plastics. A significant advantage of this method is that it uses an etching solution that does not contain chromic acid for chemical etching, which causes less pollution to the environment and helps to reduce the amount of pollution.

[0003] However, due to the influence of air humidity, such as high air humidity in summer and the water-absorbing property of high-concentration bath liquid (especially concentrated sulfuric acid), the bath liquid easily absorbs water, resulting in a decrease in bath liquid concentration, which in turn affects the roughening effect of the bath liquid on the material, thereby further affecting the quality of subsequent coatings. In order to reduce the impact of this situation on production, we propose a room temperature evaporation system that aims to reduce the water content of the bath liquid to reduce the impact of water absorption by the bath liquid.

[0032] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0036] Embodiment 1:

[0037] Reference Figures 1 to 13 This embodiment proposes a room temperature evaporation system, which is mainly used in the roughening process of ABS plastic pre-plating treatment. This embodiment preferably adopts the chromium-free roughening technology process, and the bath solution of the roughening tank 8 of this process is composed of a mixture of concentrated sulfuric acid, potassium permanganate and other solutions. Compared with chromic acid roughening, this process does not produce heavy metal pollution, thus becoming an environmentally friendly new roughening process system. However, due to the water absorption of concentrated sulfuric acid, in summer, especially in coastal cities or some southern cities with high humidity, the problem of water absorption of the bath solution is particularly prominent. After absorbing water, the concentration of the bath solution decreases, which seriously affects the roughening effect.

[0038] To this end, this embodiment proposes a room temperature evaporation system, which resists the impact of water absorption by evaporating part of the water in the tank liquid. It is worth noting that the "room temperature" mentioned in this embodiment, without additional explanation, refers to the normal temperature of the environment or the roughening tank during roughening. Generally, the better range of roughening temperature is between 60℃ and 75℃. Therefore, the "room temperature" mentioned in this embodiment can be defined as this temperature range, because within this temperature range, there is generally not much negative impact on the various equipment used in the roughening process. Therefore, evaporation at this "room temperature" is relatively safe and has little impact on the various roughening equipment. Figure 1 As shown, the normal temperature evaporation system mainly includes a coarsening tank, in which Figure 2 As shown, there are multiple roughening tanks, which are installed in parallel and spaced in two rows. Figure 2 The middle row has five coarsening pools, but other numbers are possible. There is an aisle 10 between the two rows of coarsening pools. Figure 2The left side of the middle aisle 10 is the first working side 11, and the right side of the aisle 10 is the second working side 12; a hanging device is arranged above the two rows of roughening tanks, and the hanging device is suitable for hanging materials and transferring the materials to the set position of the roughening tank for roughening. After the roughening is completed, the hanging device is also responsible for hanging and moving the materials, so as to facilitate the subsequent process. The hanging device is a common technical means in this field, and the specific model and other instructions are not given here.

[0039] like Figure 1 , Figure 3 As shown, in this embodiment, the roughening pool includes an evaporation chamber 9 and a roughening chamber 1. The evaporation chamber 9 is provided with an evaporation assembly, which includes an evaporation component and a feed component 3, wherein the evaporation assembly is mainly an evaporator therein. According to the actual ambient temperature of the roughening, the temperature used for evaporation can also be set to 60°C~75°C. On this basis, evaporation can be performed by increasing air flow and other methods. The specific evaporation means can be replaced according to actual conditions. The evaporation principle itself is not the focus of this embodiment, and therefore will not be described in detail. After evaporation, the evaporated water vapor can be condensed and discharged through the condenser. After evaporation, the concentration of the tank liquid increases, and a return component 4 is set to fill the concentrated tank liquid into the roughening chamber 1.

[0040] Among them, a part of the feed assembly 3 is located in the roughening chamber 1. Obviously, the feed assembly 3 is set at the feed position of the evaporation assembly, so at least a part of it is set at the connection with the evaporation assembly, that is, in the evaporation chamber 9, and this embodiment sets a part of the feed assembly 3 in the roughening chamber 1. The feed assembly 3 includes a feed part 14, a retractable feed channel and a drive part for providing power. The drive part is started during feeding. When the drive part is running, the gas in the feed channel is first emptied and contracted, and then the feed part 14 is opened for feeding; after the feeding is completed, the feed part 14 is automatically closed; the feed part 14 is the inlet of the evaporation assembly for absorbing the roughening tank liquid, the essence of the feed channel is a pipeline for communication, and the drive part is a device for providing suction power, generally a pump body is selected, such as a water pump. Different from the prior art, the feed channel of this embodiment is retractable. When suction is performed, the feed part 14 is obviously closed in the initial state. It must ensure that the feed channel and the roughening chamber 1 are isolated when the roughening tank is in normal working condition; it is generally through a one-way valve or other structure, and when the drive part is running, it is opened by the drive part or corresponding electrical control means (such as an electric valve).

[0041] When the driving part of the present embodiment is in operation, the "suction force" initially generated by it does not directly open the feed part 14, but first discharges the gas or liquid in the feed channel, causing the feed channel to shrink first. When the feed channel shrinks to the point where it can no longer shrink, the "suction force" generated will cause the feed part 14 to open. In this process, since the feed channel is generally arranged in the middle and lower part or the bottom of the roughening chamber 1 (it is easy to affect the normal material loading if it is arranged at the top), when the feed channel shrinks, the part where it is located will "collapse", and the tank liquid around the "collapsed" part will enter the "collapsed" position for filling. The larger the shrinkage space of the feed channel, the more obvious this effect will be. The function of the tank liquid filling the collapsed position is to instantly exchange and fuse the tank liquid near the feed channel, thereby making the tank liquid more uniform. Since the tank liquid generally absorbs water at the top In the case of insufficient stirring, the top absorbs more water, so the tank liquid concentration at this position is relatively small. In order not to affect the working range of the roughening tank, the feed channel is set at the middle and lower part or the bottom of the roughening tank. In this way, without additional treatment, the tank liquid absorbed at the bottom is relatively concentrated, so the effect after evaporation is not ideal; the feed channel is set to be retractable. When feeding, the feed channel shrinks first. At this time, the collapsed part is mostly filled with the tank liquid at the top. At the same time, due to the flow of the tank liquid, the tank liquid at the top layer of the collapsed position decreases, and the surrounding liquid will be replenished accordingly, thereby playing a better uniform effect on the overall tank liquid, and can effectively reduce the tank liquid concentration at the feed channel position (because the tank liquid with lower concentration on the top layer is mixed in), so it is easy to evaporate more water during evaporation, thereby ensuring evaporation efficiency.

[0042] The feed part 14 in this embodiment generally adopts a valve such as a one-way valve that automatically opens when receiving external force, and the contraction of the feed channel also needs to be subjected to external force. These two "external forces" actually come from the power of the driving part. Therefore, when setting, the external force required for the contraction of the feed channel needs to be smaller than the external force required for the opening of the feed part 14, so as to ensure that the feed channel contracts before the feed part 14 opens.

[0043] Embodiment 2:

[0044] This embodiment proposes a preferred solution for the feed channel. Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the feed channel includes an outer portion 31, a folding portion 32 and an inner portion 33 in sequence. The outer portion 31 is fixedly installed, and the inner portion 33 is slidably and position-limitedly installed. The sliding position-limiting installation of the inner portion 33 can refer to Figure 5 , Figure 6As shown, a limiting frame 15 is arranged outside the entire feed channel, and the inner portion 33 is not fixedly mounted with the limiting frame 15, and can slide in the inner cavity of the limiting frame 15. The folding portion 32 is suitable for extending or contracting in the sliding direction of the inner portion 33, and can be arranged as follows: Figure 5 The bellows shown has a relatively simple folding principle. Since the roughening tank solution contains concentrated sulfuric acid and may also contain potassium permanganate, the materials used in all structures in this specification do not react with the tank solution unless otherwise specified.

[0045] In the initial state, the folding part 32 is in an expanded state and is located at the bottom of the roughening chamber 1; the feed part 14 is arranged on the internal part 33, and the internal part 33 is provided with a reset structure. When feeding, the driving part operates to move the internal part 33 toward the external part 31, and the folding part 32 shrinks at the same time. After the folding part 32 is completely folded, the driving part continues to operate and the feed part 14 opens to feed. After the feeding is completed, the feed part 14 is closed, and the reset structure is suitable for moving the internal part 33 to the initial position, and the folding part 32 returns to the expanded state. Figure 3 As shown, the internally connected portion 33 is a portion of the feed channel connected to the roughening chamber 1 , and the externally connected portion 31 is a portion connected to the evaporation chamber 9 .

[0046] The following are two specific settings of the reset structure:

[0047] (1) The reset structure is provided as a first elastic reset member 16, and the first elastic reset member 16 is provided on the internally connected part 33. The driving part is provided with a pump body, and the height of the pipe outlet of the pump body in the evaporation chamber 9 is higher than the liquid level in the evaporation chamber 9. When feeding, the pump body operates to draw gas or liquid in the feeding channel to fold the folded part 32. At this time, the first elastic reset member 16 is deformed. After the feeding is completed, the pump body is closed, and the first elastic reset member 16 elastically recovers to move the internally connected part 33 back to the initial position and the folded part 32 recovers to the unfolded state. During the recovery process, the folded part 32 is supplied with air from the pipe of the pump body in the evaporation chamber 9 to prevent negative pressure from being generated when the folded part 32 recovers. The elastic reset member is preferably a spring. Of course, if Figure 3 As shown, in this embodiment, the deformation of the folding part 32 only requires the movement of the inscribed part 33. Although it will be affected by the hydraulic pressure of the tank liquid, it does not move the folding part 32 in the vertical direction, so the hydraulic pressure will not be too large. Therefore, by reasonably setting the elastic force of the first elastic reset member 16, the folding part 32 can be automatically reset after the feeding is completed.

[0048] (2) The reset structure is set as an air pump, the driving part is set as a pump body, the outlet of the air pump and the side where the pump body is connected to the feed channel are connected by a three-way pipe, and the other end of the three-way pipe is connected to the feed channel; a one-way valve is set on the side of the three-way pipe leading to the pump body; when feeding, the pump body runs, so that the one-way valve opens and draws the gas or liquid in the feed channel to fold the folded part 32, and then the feed part 14 opens to feed. After the feeding is completed, the pump body is closed, the one-way valve is closed, the air pump is turned on and pumps air into the feed channel through the three-way pipe to restore the folded part 32, and the internal part 33 moves back to the initial position. In this embodiment, an air pump is separately set up to pump air toward the folded part 32 after the feeding is completed, and the folded part 32 is restored to the unfolded state by air pressure.

[0049] In the second reset structure, in order to prevent the air pump from not stopping in time after the folded portion 32 is filled with air, the continuous injection of gas may cause the feed channel to expand and deform, thereby causing damage, such as Figure 3 As shown, a part of the feed part 14 is located outside the internally connected part 33, and a part is located inside the internally connected part 33. The outer wall of the feed part 14 located outside the internally connected part 33 is provided with a pressure relief part 24. The pressure relief part 24 is a one-way opening structure. When the air pump is running to restore the folded part 32, the air pump continues to run, and the pressure relief part 24 is opened to balance the gas. Another function of this embodiment is to pump part of the air in the evaporation chamber 9 into the folded part 32, so that the air pressure in the evaporation chamber 9 is reduced, thereby making it easier to evaporate the water.

[0050] The pressure relief portion 24 used in the tee pipe can be as follows: Figures 8 to 10 As shown, a third elastic reset member 29, a second piston 30 and a second valve core 34 are provided inside the pressure relief portion 24. The second valve core 34 has a large opening at the top and a small opening at the bottom. The second piston 30 is spherical. The third elastic reset member 29 makes the second piston 30 close to the second valve core 34 in the initial state, thereby ensuring the closed state. The top surface of the pressure relief portion 24 is in the tank liquid of the roughening tank. Under the action of the hydraulic pressure, the second piston 30 is more closely attached to the second valve core 34 to ensure the closure; and after the feeding is completed, the air pump inflates the folded part 32 to restore it. If the air pump continues to inflate, the air pressure will push the second piston 30 open, thereby ensuring that no overpressure is generated in the feeding channel. When the evaporation chamber is in a closed state, the air pump can expel the gas in the evaporation chamber 9 at this time, thereby reducing the air pressure in the evaporation chamber 9, and then facilitating evaporation.

[0051] Embodiment 3:

[0052] This embodiment proposes a preferred solution of the feed section 14. Figure 7 , Figure 8 , Figure 8The left side of the middle section does not show an opening because of the position of the section. In fact, there is an opening. The feed part 14 includes a feed tube cavity with openings on both sides. A first valve core 28 is arranged inside the feed tube cavity on one side located in the roughening chamber 1. A second elastic reset member 26 and a first piston 27 are arranged on the other side of the feed tube cavity relative to the first valve core 28. In the initial state, the second elastic reset member 26 makes the first piston 27 close to the first valve core 28 to form a closed state; when feeding, the first valve core 28 moves toward the second elastic reset member 26 and compresses the second elastic reset member 26, so that the two sides of the feed tube cavity are connected and feed; when the first piston 27 is subjected to an external force toward the first valve core 28, the first piston 27 and the first valve core 28 remain close to each other to maintain a closed state; a mounting portion 25 is opened on the outer wall of one side of the feed tube cavity located in the roughening chamber 1, and a filter assembly is detachably mounted on the mounting portion 25. The elasticity of the second elastic reset member 26 should be slightly greater than the elasticity of the first elastic reset member 16 in the reset structure (1) in Example 2.

[0053] like Figures 3 to 6 As shown, two feed channels and two feed parts 14 are respectively provided at the bottom of the roughening chamber 1; the two feed channels have opposite contraction directions. When feeding, after the folded part 32 contracts, the two folded parts 32 on both sides contract in different directions, so that the larger area at the bottom of the roughening chamber 1 generates liquid flow, thereby further mixing the tank liquid. The feed channel away from the evaporation chamber 9 passes through the roughening tank and is provided with a feed pipe 5, which bypasses the outer wall of the roughening tank and penetrates into the evaporation chamber 9 from the rear of the roughening tank; the feed channel close to one side of the evaporation chamber 9 directly penetrates and connects with the evaporation chamber 9; the feed pipes are provided on the opposite sides of the two feed channels, and the two feed pipes are respectively provided on both sides of the roughening chamber 1; the evaporation assembly includes a temperature control component and a heating component, and the temperature control component controls the heating component to keep the temperature in the evaporation chamber 9 at 60°C~75°C. The temperature control component and the heating component are common technical means in this field, so the specific equipment used can be selected according to needs.

[0054] The two feed sections 14 are as follows Figure 3 As shown, they are respectively located on both sides of the roughening chamber 1, so that when the tank liquid in the roughening chamber 1 is pumped out, water can be pumped on both sides to fill the surrounding tank liquid, thereby achieving mixing of the tank liquid in a larger range. This embodiment can be combined with the first (1) reset structure in Example 2, and a hanger 22 is set on the side of the inscribed part 33, and a first elastic reset member 16 is set between the two hangers 22 of the two inscribed parts 33 on both sides, so that the two inscribed parts 33 on both sides will be close to each other in the initial state, so that after the feeding is completed, the two inscribed parts 33 on both sides are restored to the initial position through the first elastic reset member 16.

[0055] like Figure 3As shown, the evaporation assembly is arranged on the side away from the passage 10; a feeding assembly 6 is arranged between two adjacent roughening tanks, and the feeding assembly 6 includes a feeding box for pressurized feeding and a feeding nozzle 13 penetrating the inner wall of the roughening tank.
