Description

Technical Field

[0001] This application relates to the field of rinsing apparatus, and more particularly to a countercurrent rinsing apparatus for an automated surface treatment production line. Background Technology

[0002] In the surface treatment of some workpieces, especially in the electronics industry, the requirements for rinsing are very high, and ultrapure water is often used for rinsing, resulting in a large water exchange volume. Although overflow rinsing structures used in some surface rinsing production lines can greatly reduce water consumption, they still cannot completely guarantee the thorough removal of contaminants from the workpieces. Utility Model Content

[0003] To ensure thorough removal of contaminants from workpieces and reduce the amount of water needed for cleaning, this application provides a countercurrent rinsing device for an automated surface treatment production line.

[0004] The countercurrent rinsing device for an automated surface treatment production line provided in this application adopts the following technical solution:

[0005] A countercurrent rinsing device for an automated surface treatment production line includes a cleaning tank disposed between two adjacent reaction tanks. The cleaning tank is arranged in at least two stages along the production direction of the production line, and the liquid level in the at least two stages of the cleaning tank is arranged in a stepped manner. Each cleaning tank is equipped with a spray head at its top, and the spray head located above the previous stage of the cleaning tank is connected to the water source inside the next stage of the cleaning tank. The spray head located above the last stage of the cleaning tank is connected to pure water. Each spray head is used to activate spraying after the workpiece is lifted to the corresponding position.

[0006] By adopting the above technical solution, after the workpiece is immersed in the reaction tank, it is rinsed in at least two stages of cleaning tanks according to the production line direction. After each rinse, the workpiece is sprayed with water from the next stage of cleaning tank. Since the next stage of cleaning tank is cleaner than the previous stage, after the workpiece is rinsed once, the water from the next stage of cleaning tank is used to pre-rinse the contaminants on the surface of the workpiece that have not been rinsed off before entering the next stage of cleaning tank for rinsing. This can reduce the contamination of the next stage of cleaning tank, improve the cleaning quality, and reduce the water change frequency of the next stage of cleaning tank. At the same time, the liquid after being rinsed by the spray head falls back into the cleaning tank of this stage, which can be used as replenishment water for the cleaning tank of this stage, thereby reducing the water change frequency of the cleaning tank of this stage, that is, reducing the amount of water changed.

[0007] Preferably, the spray heads are arranged on opposite sides of the cleaning tank, and multiple spray heads are spaced apart along the width of the cleaning tank.

[0008] By adopting the above technical solution, multiple spray heads are arranged at intervals along the width of the cleaning tank to ensure all-round spray cleaning of the workpiece.

[0009] Preferably, the spray head is connected to the subsequent cleaning tank via a cleaning pipe, and each cleaning pipe is connected to a power pump. The power pump is used to start when the corresponding workpiece is lifted, and the power pump is used to stop after the spray head sprays out a set flow rate of liquid.

[0010] By adopting the above technical solution, the liquid is transported from the subsequent cleaning tank to the spray head at the top of the previous cleaning tank by a power pump.

[0011] Preferably, the cleaning tanks of at least two stages include a primary cleaning tank, a secondary cleaning tank, and a tertiary cleaning tank arranged sequentially along the production line. The liquid levels in the tertiary cleaning tank, the secondary cleaning tank, and the primary cleaning tank decrease sequentially and overflow in order. The top of the primary cleaning tank is provided with an overflow port. When the liquid level rises to the height of the overflow port, the tank liquid is discharged from the overflow port.

[0012] By adopting the above technical solution, the workpiece is first cleaned in the primary cleaning tank, which can wash away most of the chemical liquids adhering to the workpiece surface. After the workpiece is lifted, it is sprayed in the primary cleaning tank to rinse away the contaminants adhering to the workpiece surface. The water after rinsing falls into the primary cleaning tank, which can replenish the water in the primary cleaning tank to a certain extent, reducing the water exchange volume of this cleaning tank. Then the workpiece passes through the secondary and tertiary cleaning tanks for rinsing, as well as the secondary and tertiary sprays, to complete the cleaning of the workpiece. By setting the liquid level height in the primary, secondary, and tertiary cleaning tanks, the liquid can be replenished sequentially from the tertiary cleaning tank to the secondary cleaning tank and then to the primary cleaning tank, reducing the water exchange volume. At the same time, when the liquid level in the primary cleaning tank rises to the overflow port height, the tank liquid is discharged from the overflow port.

[0013] Preferably, the three-stage cleaning tank is equipped with a concentration detector for detecting the concentration of waste liquid.

[0014] By adopting the above technical solution, the liquid concentration in the three-stage cleaning tank is detected by a concentration detector. When the liquid concentration exceeds the concentration threshold, the water in the first-stage cleaning tank, the second-stage cleaning tank, and the third-stage cleaning tank are changed at the same time.

[0015] Preferably, each of the three cleaning tanks is equipped with an ultrasonic generator for producing ultrasonic waves.

[0016] By adopting the above technical solution, an ultrasonic generator is installed in the three-stage cleaning tank, thereby performing ultrasonic cleaning on the workpiece during washing and improving the cleaning effect on the workpiece.

[0017] Preferably, each of the cleaning tanks at each level is movably provided with an openable and closable cover, and the spray head is located on the inner side of the cover.

[0018] By adopting the above technical solution, a cover plate is movably installed on the top of the cleaning tank. When the workpiece moves to the top of the corresponding cleaning tank, the cover plate automatically opens. When the workpiece is cleaned and moves to the top of the next cleaning tank, the cover plate on the top of the previous cleaning tank automatically closes to prevent other impurities from falling in.

[0019] Preferably, there is an installation gap between the top surface of the cleaning tank and the table surface of the production line for arranging pipelines. Several of the spray heads are integrated on a water distribution pipe, which is connected to the cleaning pipe and is located within the installation gap.

[0020] By adopting the above technical solution, various water pipes are arranged within the installation gaps, ensuring the cleanliness of the production line surface.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application sets up a multi-stage cleaning tank, with a spray head installed at the top of each stage. The spray head is connected to the next stage cleaning tank. After rinsing, the workpiece is sprayed and rinsed with the relatively clean water in the next stage cleaning tank. This can pre-wash away contaminants attached to the workpiece, reducing contamination of the next stage cleaning tank and thus reducing the water change frequency of the next stage cleaning tank. At the same time, the water dripping from the spray can be used as replenishment water for the cleaning tank, reducing the water change frequency of the current stage cleaning tank. Therefore, this application can improve the cleaning quality of the workpiece while reducing the amount of water changed, achieving the effects of water saving, energy saving and emission reduction.

[0023] 2. By installing ultrasonic generators in all three cleaning tanks, ultrasonic cleaning of the workpieces is performed, thereby improving the cleaning effect. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a countercurrent rinsing device for an automated surface treatment production line. (Refer to...) Figures 1-4 A countercurrent rinsing device for an automated surface treatment production line includes a cleaning tank 01 positioned between two adjacent reaction tanks, with the liquid levels in at least two cleaning tanks 01 arranged in a stepped manner. Each cleaning tank 01 has a spray head 5 installed at its top, and the spray head 5 located above the preceding cleaning tank 1 is connected to the water source inside the following cleaning tank 1, while the spray head 5 located above the final cleaning tank 01 is connected to pure water. Each spray head 5 is used to activate the spraying after the workpiece is lifted to the corresponding position. This application uses a three-stage countercurrent rinsing process as an example, with a first-stage cleaning tank 1, a second-stage cleaning tank 2, and a third-stage cleaning tank 3 arranged sequentially along the production line direction. The liquid levels in the third-stage cleaning tank 3, the second-stage cleaning tank 2, and the first-stage cleaning tank 1 decrease sequentially, satisfying the requirement of sequential overflow. A first-stage spray is installed above the first-stage cleaning tank 1, a second-stage spray is installed above the second-stage cleaning tank 2, and a third-stage spray is installed above the third-stage cleaning tank 3. The primary spray is connected to the secondary cleaning tank 2 via cleaning pipe 9, the secondary spray is connected to the tertiary cleaning tank 3 via cleaning pipe 9, and the tertiary spray is connected to an external pure water source.

[0031] During rinsing, the workpiece first undergoes a primary cleaning in tank 1 to initially remove most of the chemical liquid adhering to its surface. After the workpiece is lifted, the primary spray is activated to rinse away the contaminants on its surface. The rinsed water falls back into tank 1, replenishing the tank and reducing the water exchange volume in this tank. The workpiece then passes through tank 2 for rinsing, and after being lifted, undergoes a secondary spray in tank 3 to remove most of the contaminants. It then enters tank 3 for rinsing, followed by a final rinse using the tertiary spray to ensure the cleaning quality. By setting the liquid levels in tanks 1, 2, and 3, the system allows for sequential replenishment of liquid from tank 3 to tank 2 and then back to tank 1, minimizing water exchange. Tank 1 has an overflow outlet 11 at its top; when the liquid level reaches the overflow outlet 11, the liquid is discharged.

[0032] The spray head 5 is connected to the subsequent cleaning tank 1 through the cleaning pipe 9, and each cleaning pipe 9 is connected to a power pump 10. The power pump 10 is used to start when the corresponding workpiece is lifted, and the power pump 10 is used to stop after the spray head 5 sprays out the set flow rate of liquid.

[0033] Spray heads 5 are arranged on opposite sides of the cleaning tank 01, and multiple spray heads are spaced apart along the width of the cleaning tank 01.

[0034] The tertiary cleaning tank 3 is equipped with a concentration detector for detecting the concentration of waste liquid. The concentration of the liquid in the tertiary cleaning tank 3 is detected by the concentration detector. When the liquid concentration exceeds the concentration threshold, the water in the primary cleaning tank 1, the secondary cleaning tank 2 and the tertiary cleaning tank 3 is replaced.

[0035] An ultrasonic generator is also installed in the three-stage cleaning tank 3 to generate ultrasonic waves, which cleans the workpieces ultrasonically during the washing process, thereby improving the cleaning effect.

[0036] Each cleaning tank 01 has an automatically opening and closing cover 4 on its top, with spray heads 5 located inside the cover 4. An installation gap 7 exists between the top surface of each cleaning tank 01 and the production line table 6 for pipe routing. Several spray heads 5 are integrated onto a single water distribution pipe 8, which is connected to an external water source via a cleaning pipe 9. The water distribution pipe 8 is located within the installation gap 7. This design makes the table 6 cleaner.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
