[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] The auxiliary vacuum extraction method during or after solvent surface treatment cannot completely prevent the occurrence of related surface treatment quality defects, but it will cause a large amount of solvent surface treatment liquid (especially volatile solvents) to evaporate, affecting the solvent concentration, changing the ratio, easily causing quality defects, and possibly damaging the environment.

[0038] Based on this, the present invention proposes a surface treatment auxiliary device.

[0039] See also Figure 1 In one embodiment of the present invention, the surface treatment auxiliary device 100 comprises:

[0040] The storage box 1 has an open cavity 11 formed inside, and the cavity 11 is used to store the treatment liquid;

[0041] A surface treatment component is installed at the open portion, and the surface treatment component is provided with a treatment tank 221, and the treatment tank 221 is used to perform surface treatment on the target part to be treated, and the treatment tank 221 is immersed below the liquid level of the treatment liquid; and

[0042] The vacuum tank 3 is installed in an open place and spaced apart from the surface treatment component. The bottom of the vacuum tank 3 is immersed below the liquid surface of the treatment liquid. The vacuum tank 3 is used to place the target part, and the target part is transferred to the inside of the treatment tank 221 for surface treatment after being evacuated by the vacuum tank 3.

[0043] In the technical solution of the present invention, a cavity 11 is formed inside the storage box 1, and the cavity 11 is used to store the solvent treatment liquid. A surface treatment component and a vacuum tank 3 are arranged at intervals above the storage box 1, and the bottom of the vacuum tank 3 and the treatment tank 221 in the surface treatment component are immersed below the liquid surface of the treatment liquid. In this way, the target part is first placed in the vacuum tank 3 for vacuum treatment, so as to clean the dirt, bubbles or other impurities on the surface of the target part, thereby improving the subsequent surface treatment quality of the target part. Since the target part is transferred to the treatment tank 221 in the treatment liquid after flowing out from the bottom of the vacuum tank 3, it does not contact the air during this process, but is always immersed in the treatment liquid, ensuring that the treatment liquid can penetrate well into the blind hole of the target part. The change of the solvent concentration ratio is reduced during the entire treatment process, and the quality of the solvent surface treatment is effectively improved.

[0044] Specifically, there is no specific limitation on the structure of the surface treatment component, for example, it can be an electroplating device or a vibration plating machine 2, etc., as long as it is a structure that needs to be surface treated in a solvent environment. In order to ensure the effect of vacuuming the target part in the vacuum tank 3, the vacuum tank 3 is usually a closed container. For example, a switch that can be opened or closed can be provided at the bottom of the vacuum tank 3. After the vacuuming is completed, the switch is turned on to allow the target part to fall and be transferred to the treatment tank 221. It should be noted that in order to ensure that the treatment liquid in the cavity 11 can immerse the bottom of the vacuum tank 3 and the treatment tank 221, scale lines can also be provided on the inner wall of the storage box 1, such as 3L, 5L, 7L, etc. Through the marking of the scale lines, the amount of solvent added each time can have a clear measurement unit, which is convenient for the subsequent replenishment of the treatment liquid in the cavity 11.

[0045] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 , the surface treatment auxiliary device 100 also includes a material guide member, which is immersed in the treatment liquid, and one end of the material guide member is arranged below the vacuum tank 3, and the other end of the material guide member extends into the treatment tank 221, so as to transfer the target part from the vacuum tank 3 to the treatment tank 221. The setting of the material guide member allows the target part to be accurately and smoothly transferred between the vacuum tank 3 and the treatment tank 221, and avoids the situation where the target part falls into the cavity 11. The target part that has been vacuumed is directly transferred to the treatment tank 221 by the material guide member, which simplifies the operation process and improves the production efficiency. In addition, during the transfer process, the material guide member is always immersed in the treatment liquid, which can prevent the target part from contacting with the external environment during the transfer process, reduce the risk of contamination, and ensure the consistency and cleanliness of the surface treatment. In this embodiment, there is no specific limitation on the shape of the material guide member, for example, it can be a funnel shape, or a tubular channel, etc.

[0046] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 The material guide member includes a material guide plate 4, which is bent toward the open direction to form a slide 41, and the two ends of the slide 41 are respectively connected to the vacuum tank 3 and the processing tank 221. The setting of the slide 41 allows the target part to slide smoothly during the transfer from the vacuum tank 3 to the processing tank 221. The structure of the slide 41 helps to guide the flow of the processing liquid and reduce the splashing of the processing liquid during the transfer process. In addition, the bending setting of the material guide plate 4 can prevent small parts such as PIN connectors from slipping off the two sides of the material guide plate 4 during the transfer process. In addition, the two ends of the slide 41 are respectively connected to the vacuum tank 3 and the processing tank 221. This closed transfer path effectively prevents the target part from falling.

[0047] In the embodiments of the present invention, please refer to Figure 4 The width of the chute 41 decreases from the end close to the vacuum tank 3 to the end close to the processing tank 221. That is to say, the width of the chute 41 close to the vacuum tank 3 is larger, which can effectively receive a plurality of small PIN connectors and other small parts dropped from the bottom of the vacuum tank 3; the width of the chute 41 close to the vacuum tank 3 is smaller, so that the flow rate of the PIN connector flowing from the chute 41 into the processing tank 221 is smaller, which can ensure that the PIN connector is fully surface treated in the processing tank 221, thereby improving the surface treatment quality. The decreasing width setting in the guide plate 4 can gradually guide the target part to be smoothly transferred from the vacuum tank 3 to the processing tank 221, ensuring the smoothness and accuracy of the transfer process.

[0048] In the embodiments of the present invention, please refer to Figure 2 and Figure 3The guide plate 4 is tilted, and the guide plate 4 tilts from one end close to the vacuum tank 3 to the end close to the processing tank 221 in a direction away from the opening. The tilted guide plate 4 uses the gravity-assisted effect to achieve the transfer of the target part from the vacuum tank 3 to the processing tank 221, reducing the power required during the transfer process and improving energy efficiency. In addition, the tilted setting makes it easier for bubbles on the target part to rise and be discharged in the processing liquid. It should be pointed out that the tilt angle of the guide plate 4 is not specifically limited and can be adjusted according to actual needs.

[0049] In the embodiments of the present invention, please refer to Figures 1 to 3 , the surface treatment auxiliary device 100 also includes a conducting tube 5, one end of which is connected to the vacuum tank 3, and the other end of the conducting tube 5 extends into the cavity 11, and the conducting tube 5 is used to transport the treatment liquid. That is to say, one end of the conducting tube 5 extends into the interior of the vacuum tank 3, and the other end is connected to the solvent surface treatment liquid (immersed under the liquid level of the treatment liquid). Optionally, the conducting tube 5 can also be connected to an air pump, and the treatment liquid can be reciprocated between the vacuum tank 3 and the storage box 1 through the air pump, so that the vacuum tank 3 has three states of vacuum, air and solvent treatment liquid. In this way, the target part is first evacuated in the vacuum tank 3, and then the treatment liquid is added to the vacuum tank 3 through the conducting tube 5, so that the target part is soaked by the treatment liquid while maintaining the vacuum state, which increases the soaking time of the treatment liquid on the target part, ensures that the treatment liquid can completely fill the blind hole on the target part, and then improves the solvent surface treatment effect on the target part. Optionally, a ball valve switch is also provided on the conducting tube 5, and the on-off of the conducting tube 5 is controlled by the ball valve switch. In general, this solution can not only enable the processing liquid to enter the blind hole of the target part to ensure the processing quality, but also avoid the volatilization of substances in the processing liquid when the processing liquid is vacuumed.

[0050] In the embodiments of the present invention, please refer to Figure 5 , the surface treatment auxiliary device 100 also includes a lifting component 6, which is installed on the storage box 1 and is connected to the vacuum tank 3 to drive the vacuum tank 3 to rise or fall. Optionally, the lifting component 6 includes a slide rail and a slider fixedly connected to the vacuum tank 3, and the slider is fixedly connected to the vacuum tank 3. The rise or fall of the vacuum tank 3 is achieved by sliding the slider up and down on the slide rail. Of course, a telescopic cylinder can also be provided to provide sliding power for the slider. In this way, by installing the lifting component 6, the convenient lifting and lowering of the vacuum tank 3 is achieved. When the vacuum tank 3 needs to be in a treatment liquid environment, the lifting component 6 can quickly lower the vacuum tank 3 to an appropriate position, so that the treatment liquid can enter the tank smoothly, ensuring the solution treatment effect of the target part; when the treatment liquid does not need to be stored in the vacuum tank 3, the vacuum tank 3 is driven to rise by the lifting component 6, so that the vacuum tank 3 is separated from the treatment liquid, and the treatment liquid is prevented from entering the tank body through the bottom of the vacuum tank 3.

[0051] In the embodiments of the present invention, please refer to Figure 2 , the vacuum tank 3 comprises:

[0052] The tank body 31 is mounted on the storage box 1, and the tank body 31 is provided with an upper opening and a lower opening communicating with the interior thereof, and the lower opening is immersed in the treatment liquid;

[0053] An upper cover 32, mounted on the upper opening to open or close the upper opening; and

[0054] The lower cover 33 is installed at the lower opening to open or close the lower opening.

[0055] Specifically, the tank body 31 is provided with an upper opening and a lower opening, and is opened or closed by an upper cover 32 and a lower cover 33, respectively, to ensure good sealing performance of the vacuum tank 3 during the vacuuming process and prevent external air from entering. The lower opening is immersed in the treatment liquid, and by opening and closing the lower cover 33, the target part can be quickly immersed in the treatment liquid, which reduces the operation time and improves the efficiency of the surface treatment. Optionally, the lower cover 33 and the upper cover 32 are opened or closed by a handle.

[0056] In the embodiments of the present invention, please refer to Figures 1 to 3 The vacuum tank 3 is also provided with a vacuum interface 321, which is provided on the upper cover 32. The vacuum interface 321 is used to connect with external vacuum equipment and communicate with the interior of the tank body 31. The setting of the vacuum interface 321 enables the vacuum tank 3 to be easily connected with external vacuum equipment, and the vacuum degree can be adjusted according to different processing requirements, so as to realize the vacuum operation inside the tank body 31. In addition, the vacuum interface 321 can be integrated with the monitoring system of the vacuum equipment to facilitate real-time monitoring of the vacuum state inside the tank body 31 and ensure the stability of the surface treatment process. Optionally, a ball valve switch is also provided on the vacuum interface 321, and the on-off of the vacuum pipeline can be controlled by the ball valve switch.

[0057] In the embodiments of the present invention, please refer to Figures 1 to 3 The vacuum tank 3 also includes a barometer 322, which is installed on the upper cover 32 and is used to measure the internal air pressure of the tank body 31. The reading provided by the barometer 322 can accurately control the vacuum degree inside the vacuum tank 3 to meet the requirements of different surface treatment processes. The barometer 322 is directly installed on the upper cover 32, which is convenient for operators to read the air pressure data without opening the tank body 31, thereby improving the convenience of operation. By monitoring the air pressure, it is possible to prevent treatment failures caused by abnormal air pressure and ensure the quality of surface treatment.

[0058] In the embodiments of the present invention, please refer to Figures 1 to 3, the surface treatment auxiliary device 100 also includes a pressure relief component 323, which is installed on the upper cover 32 and is connected to the interior of the tank body 31. When the vacuum tank 3 needs to be opened for operation or maintenance, the pressure relief component 323 can quickly release the internal pressure. Rapid pressure relief can prevent damage to the vacuum tank 3 and its internal parts due to excessive internal pressure, and avoid potential dangers caused by pressure differences. In addition, after the target part is processed, the installation of the pressure relief component 323 enables the vacuum state in the vacuum tank 3 to be quickly converted to a normal pressure state, thereby improving operational efficiency and flexibility. Optionally, the pressure relief component 323 includes a pressure relief pipe and a ball valve switch, and the ball valve switch can control the on and off of the pressure relief component 323 and adjust the flow of gas in the pressure relief component 323.

[0059] In the embodiments of the present invention, please refer to Figures 1 to 3 The surface treatment auxiliary device 100 also includes a safety valve 324, which is installed on the upper cover 32 and communicated with the interior of the tank body 31. The installation of the safety valve 324 ensures that when the air pressure in the vacuum tank 3 exceeds the preset safety value, it can be automatically opened to release excess pressure and prevent excessive pressure from causing damage to the equipment. In addition, the use of the safety valve 324 in conjunction with the pressure relief component 323 can improve the pressure relief efficiency of the vacuum tank 3, provide double safety protection for the vacuum tank 3, and greatly reduce the safety risks during operation.

[0060] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 , the surface treatment component is a vibration plating machine 2, which includes a vibration source 21 and a vibration screen 22. The vibration source 21 is installed above the storage box 1 and is connected to the vibration screen 22 by driving. A processing tank 221 is formed inside the vibration screen 22. The vibration source 21 of the vibration plating machine 2 can make the processing tank 221 in the vibration screen 22 vibrate uniformly, thereby ensuring that the target part is fully in contact with the treatment liquid during the treatment process, thereby improving the uniformity of the surface treatment. The driving connection between the vibration source 21 and the vibration screen 22 enables the target part in the processing tank 221 to quickly and evenly contact the treatment liquid, thereby accelerating the speed of surface treatment and improving production efficiency. It should be noted that the vibration plating machine 2 can adjust the vibration frequency and amplitude according to different processing requirements to adapt to target parts of different types and sizes. The vibration effect of the vibration plating machine 2 also helps to optimize the flow distribution of the treatment liquid, reduce the dead corners in the processing tank 221, and ensure that every corner can be treated evenly.

[0061] The specific processing process of the target part of the present invention is as follows: first, fix the lower cover 33 on the vacuum tank 3, put the target part into the vacuum tank 3 and then fix the upper cover 32, turn on the switch on the vacuum interface 321 to evacuate the vacuum tank 3, and close the switch on the vacuum interface 321 after the evacuation is completed; then, turn on the ball valve switch on the conducting pipe 5, so that the vacuum tank 3 is filled with the processing liquid, and then close the ball valve switch on the conducting pipe 5; finally, turn on the ball valve switch on the pressure relief assembly 323, open the lower cover 33, and transfer the target part to the processing tank 221 through the material guide 4 for surface treatment.

[0062] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
