Description

[0030] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0031] like Figure 1 and Figure 6As shown in the figure, this embodiment provides a tank liquid turning device, including a shed 1, a silane liquid tank 2 and a passivation liquid tank 3 are provided at one end of the shed 1, a PLC controller 10 is fixedly installed on the side wall of the shed 1, a silane liquid recovery tank 8 and a passivation liquid recovery tank 9 are provided at the bottom of the shed 1, and an outlet pipe 11 is fixedly connected to the bottom of the shed 1. The shed 1 includes a turning mechanism 7.

[0032] The bottom end of the liquid outlet pipe 11 is fixedly sleeved with a housing 71. A turning groove 72 is opened inside the housing 71, and sealing grooves 73 are symmetrically opened on the inner wall of the turning groove 72. A servo motor 74 is fixedly installed on one side of the housing 71. A hollow rotating shaft 75 is fixedly sleeved on the output shaft of the servo motor 74. One end of the hollow rotating shaft 75 passes through the inner wall of the turning groove 72 and extends to the other side of the housing 71. Two automatic deflection plates 76 are fixedly connected to the surface of the hollow rotating shaft 75. The automatic deflection plates 76 are slidably connected to the inner wall of the sealing groove 73.

[0033] A silane liquid recovery tube 81 is fixedly sleeved on one side of the bottom end of the outer shell 71. The bottom end of the silane liquid recovery tube 81 is fixedly sleeved on the top end of the silane liquid recovery box 8. A passivation liquid recovery tube 91 is fixedly sleeved on the other side of the bottom end of the outer shell 71. The bottom end of the passivation liquid recovery tube 91 is fixedly sleeved on the top end of the passivation liquid recovery box 9.

[0034] Specifically, when the device is using silane solution, the waste silane solution flows out through the outlet pipe 11 at the bottom of the shed 1. At this time, the PLC controller 10 controls the servo motor 74 to start. The servo motor 74 drives the hollow shaft 75 to rotate. The hollow shaft 75 drives the automatic redirection plate 76 to rotate. When the automatic redirection plate 76 rotates to a certain angle and reaches the inner wall of the sealing groove 73, it opens the channel to the silane solution recovery pipe 81 and closes the channel to the passivation solution recovery pipe 91. This will guide the solution flowing out of the outlet pipe 11 towards the silane solution recovery tank 8, so that the silane solution flows into the silane solution recovery tank 8, thereby realizing the recovery of the silane solution.

[0035] When the device is using the passivation solution, the waste passivation solution also flows out through the outlet pipe 11. The PLC controller 10 controls the servo motor 74 again, causing it to drive the hollow rotating shaft 75 to rotate. The automatic redirecting plate 76 also rotates accordingly, turning the automatic redirecting plate 76 to another angle, opening the channel to the passivation solution recovery pipe 91 and closing the channel to the silane solution recovery pipe 81. This guides the solution flowing out of the outlet pipe 11 into the passivation solution recovery tank 9, thus realizing the recovery of the passivation solution.

[0036] In a further embodiment, the automatic deflector plate 76 has a deflection groove 77 inside, and a manual deflector plate 78 is rotatably connected inside the hollow shaft 75. One end of the manual deflector plate 78 passes through the hollow shaft 75 and is fixedly sleeved with a wheel 79. Bolts 711 are threadedly connected to the same end surface of the hollow shaft 75 and the manual deflector plate 78. Two manual deflector plates 710 are fixedly connected to the surface of the manual deflector plate 78. The manual deflector plates 710 are fitted into the inner wall of the deflection groove 77.

[0037] Specifically, when the servo motor 74 malfunctions or requires manual intervention, firstly, unscrew the bolt 711 to release the fixation between the manual rotating shaft 78 and the hollow rotating shaft 75. Rotate the rotating wheel 79, which drives the manual rotating shaft 78 to rotate inside the hollow rotating shaft 75. The manual rotating shaft 78 drives the manual redirection plate 710 to rotate. Since the manual redirection plate 710 is fitted into the inner wall of the redirection groove 77 inside the automatic redirection plate 76, when the manual redirection plate 710 changes angle, the redirection groove 77 will open, thereby changing the flow direction of the tank liquid and realizing manual control of the tank liquid's direction. After the adjustment is completed, tighten the bolt 711 to fix the manual rotating shaft 78 and the hollow rotating shaft 75 together, preventing them from rotating accidentally, improving the reliability and flexibility of the device, and ensuring accurate recovery of the tank liquid under different conditions.

[0038] In a further embodiment, a first water pump 21 is fixedly installed at the top of the silane liquid tank 2. A first liquid extraction pipe is fixedly sleeved at the input end of the first water pump 21. One end of the first liquid extraction pipe extends into the interior of the silane liquid tank 2. A silane liquid pipe 22 is fixedly sleeved at the output end of the first water pump 21. A first solenoid valve 23 is fixedly sleeved at the lower part of the silane liquid pipe 22. The top of the first solenoid valve 23 is fixedly sleeved at one side of the opening of the Y-shaped liquid pipe 4.

[0039] A second water pump 31 is fixedly installed at the top of the passivation solution tank 3. A second liquid extraction pipe is fixedly connected to the input end of the second water pump 31. The bottom end of the second liquid extraction pipe extends into the interior of the passivation solution tank 3. A passivation solution pipe 32 is fixedly connected to the output end of the second water pump 31. A second solenoid valve 33 is fixedly connected to the lower surface of the passivation solution pipe 32. The top end of the second solenoid valve 33 is fixedly connected to the other side of the Y-shaped liquid pipe 4.

[0040] One end of the Y-shaped liquid pipe 4 is fixedly sleeved with an infusion pipe 5. One end of the infusion pipe 5 passes through the side wall of the shed 1 and extends into its interior. Several spray pipes 6 are fixedly sleeved on the lower surface of the infusion pipe 5. The several spray pipes 6 are arranged at equal intervals.

[0041] Specifically, when silane solution is needed, the PLC controller 10 controls the first water pump 21 to start. The first water pump 21 draws silane solution from the silane solution tank 2 through the first extraction pipe. After the silane solution is drawn, it enters the silane solution pipe 22 through the output end of the first water pump 21. At this time, the PLC controller 10 controls the first solenoid valve 23 to open. The silane solution flows along the silane solution pipe 22 through the first solenoid valve 23 and enters one side of the Y-shaped liquid pipe 4. The silane solution enters the infusion pipe 5 from the Y-shaped liquid pipe 4, and then is evenly sprayed onto the workpiece to be treated inside the shed 1 from several equally spaced spray pipes 6 below the infusion pipe 5.

[0042] When passivation solution is needed, PLC controller 10 controls the second water pump 31 to start. The second water pump 31 draws passivation solution from the passivation solution tank 3 using the second suction pipe. The drawn passivation solution enters the passivation solution pipe 32 through the output end of the second water pump 31. Then, PLC controller 10 controls the second solenoid valve 33 to open. After passing through the passivation solution pipe 32 and the second solenoid valve 33, the passivation solution enters the other side of the Y-shaped liquid pipe 4. Then, it is evenly sprayed onto the workpiece inside the shed 1 through the spray pipe 6 on the lower surface of the infusion pipe 5.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
