Description

Technical Field

[0001] This application relates to the field of electrophoretic pretreatment technology, and in particular to electrophoretic pretreatment tanks with ultrasonic cleaning function. Background Technology

[0002] In electrophoretic coating, the quality of metal part pretreatment directly affects coating adhesion, corrosion resistance, and appearance. Traditional pretreatment tanks typically employ chemical immersion or ultrasonic cleaning alone. Static immersion is insufficient to completely remove stubborn grease from blind holes and irregularly shaped parts. While ultrasonic cleaning can remove contaminants through cavitation, the poor fluidity of the tank liquid causes grease to re-adhere to the workpiece surface. The grease removed during cleaning tends to accumulate on the liquid surface, requiring frequent shutdowns for manual cleaning, which severely restricts production continuity. Utility Model Content

[0003] To improve the problems of insufficient liquid flow and oil suspension, this application provides an electrophoretic pretreatment tank with ultrasonic cleaning function.

[0004] The electrophoretic pretreatment tank with ultrasonic cleaning function provided in this application adopts the following technical solution:

[0005] An electrophoretic pretreatment tank with ultrasonic cleaning function includes a cleaning tank. A first groove is provided on one side of the surface of the cleaning tank. A functional plate with a Teflon coating is slidably connected through the inside of the first groove. A rotating shaft is fixedly connected to the inner wall of the cleaning tank. A scraper is rotatably connected through the surface of the rotating shaft.

[0006] By adopting the above technical solution, a first sliding groove is opened on the surface of the cleaning tank, and a functional plate with a Teflon coating is sprayed through it on the sliding connection surface. The Teflon coating has an extremely low coefficient of friction and good corrosion resistance, which can reduce the frictional resistance when the functional plate slides, while preventing the cleaning fluid from corroding the functional plate and extending the service life of the equipment.

[0007] Preferably, a torsion spring is fitted on the surface of the rotating shaft, one end of which is fixedly connected to the surface of the scraper, and the other end of the torsion spring is fixedly connected to a baffle that is rotatably connected to the surface of the rotating shaft.

[0008] By adopting the above technical solution, a rotating shaft is fixed on the inner wall of the cleaning tank, and a scraper is rotatably connected through the surface of the shaft. The scraper can rotate around the shaft, which facilitates scraping the functional plates, effectively removing grease and impurities adhering to the functional plates, and improving the cleaning effect.

[0009] Preferably, the surface of the scraper is provided with a collection groove, and an adsorption tube is fixedly connected to both ends of the inner wall of the collection groove.

[0010] By adopting the above technical solution, the collection tank can collect the grease and impurities scraped off by the scraper, and the adsorption tube uses negative pressure to suck the grease and impurities out of the tank, keeping the inside of the tank clean.

[0011] Preferably, gears are fixedly connected to both ends of the scraper, a rack is meshed with one side of the gear, and a movable column is fixedly connected to one side of the rack.

[0012] By adopting the above technical solution, the rack and pinion are used to control the contact between the scraper and the functional plate.

[0013] Preferably, an auxiliary plate is fixedly connected to one side of the surface of the cleaning tank, and a limiting groove is symmetrically opened on one side of the surface of the auxiliary plate. A slider that is slidably connected to the moving column is slidably connected inside the limiting groove, and a connecting rod that is fixedly connected to the surface of the functional plate is fixedly connected to one side of the surface of the slider.

[0014] By adopting the above technical solution, the slider slides within the limiting groove, providing guidance for the linear movement of the moving column and ensuring the stability of the function plate movement.

[0015] Preferably, the surface of the slider is provided with a second groove, and the interior of the second groove is slidably connected to a first cylinder that is fixedly connected to the surface of the moving column. The surface of the auxiliary plate is symmetrically provided with a first inclined plate and a second inclined plate that are slidably connected to the first cylinder.

[0016] By adopting the above technical solution, the first inclined plate and the second inclined plate are used to control the meshing of the gear and the rack.

[0017] Preferably, a limiting shell that communicates with the interior of the first sliding groove is fixedly connected to one side of the surface of the cleaning tank. A movable plate is slidably connected inside the limiting shell. An inclined groove is opened through the surface of the movable plate. A second cylinder that is fixed to the surface of the functional plate is slidably connected inside the inclined groove.

[0018] By adopting the above technical solution, the horizontal displacement of the inclined slot is converted into the vertical movement of the functional board.

[0019] Preferably, a second connecting rod is fixedly connected to the surface of the movable plate, penetrating the interior of the limiting shell. A push plate that is slidably connected to the end of the second connecting rod away from the limiting shell is fixedly connected to the end of the push plate that is slidably connected to the interior of the cleaning tank. The surface of the push plate has linearly arranged toothed grooves. An electric push rod is fixedly connected to the surface of the cleaning tank. The output end of the electric push rod is fixedly connected to the surface of the push plate.

[0020] By adopting the above technical solution, the electric actuator provides power to the push plate, driving the push plate to perform reciprocating linear motion, and then drives the functional plate to slide through the second connecting rod and the moving plate to realize the automated cleaning of the cleaning tank.

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

[0022] 1. By using the push plate and toothed groove to drive the hanger to shake, the static boundary layer on the workpiece surface is broken, which improves the contact efficiency of ultrasonic cavitation bubbles. It is especially effective for cleaning deep holes / blind holes, allowing grease to quickly detach from the workpiece surface. By setting up a Teflon-coated functional plate, the grease is adsorbed by the functional plate through liquid shaking.

[0023] 2. The scraper is driven by gears and racks. It automatically scrapes off the grease on the surface of the function plate after each stroke. When the electric push rod drives the moving plate to move horizontally, the horizontal displacement is converted into the vertical movement of the function plate through the inclined groove, which in turn drives the rack to drive the gear to rotate. This ensures that the scraper does not contact the function plate when the function plate moves up, and scrapes off the grease and impurities by the scraper adhering to the surface of the function plate when the function plate moves down. The scraper reciprocates and scrapes the oil with the help of the torsion spring. No additional power source is required throughout the process.

[0024] 3. A first inclined plate and a second inclined plate are set at the upper and lower ends of the rack. When the oil scraping stroke ends, the second inclined plate moves the rack and the gear to a different plane through the first cylinder to avoid interference with the rack when it goes down, so that the scraper can fit with the function plate when it goes down. The first inclined plate ensures that the rack and the gear re-mesh after the reset, forming an automatic cycle. Attached Figure Description

[0034] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0035] This application discloses an electrophoretic pretreatment tank with ultrasonic cleaning function.

[0036] Reference Figure 2 , Figure 4 An electrophoretic pretreatment tank with ultrasonic cleaning function includes a cleaning tank 1. A first groove 2 is formed on the upper surface of the cleaning tank 1. The inner wall of the first groove 2 is slidably connected to the outer wall of a functional plate 3. The inner side of the top of the functional plate 3 is attached to the upper surface of the cleaning tank 1, and the end of the functional plate 3 away from the first groove 2 is attached to the inner side of the cleaning tank 1. The outer wall of the functional plate 3 inside the cleaning tank 1 is coated with a Teflon coating. The two sides of the inner wall of the cleaning tank 1 are fixed to the two ends of a rotating shaft 4. The surface of the rotating shaft 4 is rotatably connected to the inner wall of a scraper 5. The scraper 5 is located... The middle part of the rotating shaft 4 has a gap, and a torsion spring 6 is fitted in the middle gap of the rotating shaft 4. One end of the torsion spring 6 is fixed to the baffle 7. The bottom end of the baffle 7 is rotatably connected to the rotating shaft 4. The other end of the torsion spring 6 is fixed to the surface of the scraper 5. The scraper 5 is hook-shaped, and one side of the hook can abut against the coating side of the functional plate 3 for scraping off adsorbed grease. The surface of the hook of the collection tank 8 is provided with a collection tank 8. The two ends of the inner wall of the collection tank 8 are fixedly connected to two adsorption tubes 9 respectively. The ends of the two adsorption tubes 9 away from the collection tank 8 can be connected to a negative pressure suction device through a tube.

[0037] Teflon coating has extremely low surface energy, making it one of the most hydrophobic materials known. It also exhibits excellent affinity for grease, allowing grease to easily spread and form a continuous oil film on its surface. Its non-stick property results in very weak adhesion between the grease layer and the Teflon coating substrate. The scraper 5 easily removes most of the grease layer in one piece, leaving very little residue. The upward movement of the functional plate 3 causes the scraper 5 to rotate, preventing grease impurities from being scraped into the water during upward movement. When the functional plate 3 moves downward, the scraper 5 adheres to and abuts against the coating surface of the functional plate 3 via the torsion spring 6. The downward movement of the functional plate 3 scrapes the grease layer into the collection tank 8. A negative pressure suction pump is then activated to absorb impurities in the collection tank 8, reducing contamination and extending its service life.

[0038] Reference Figure 5 , Figure 6The scraper 5 has two ends fixed to the surfaces of two gears 10, and the two gears 10, on the side away from the functional plate 3, mesh with a rack 11. The top surface of the rack 11 is fixed to the outer surface of the moving column 13. The outer side of the cleaning tank 1 near the functional plate 3 is fixedly connected to the inner side of the auxiliary plate 20. The bottom of the first chute 2 abuts against the surface of the baffle 7. Two limiting grooves 19 are provided on the inner side of the auxiliary plate 20 away from the functional plate 3. The two limiting grooves 19 are symmetrically arranged. The inner walls of the two limiting grooves 19 are slidably connected to the outer wall of a slider 12. The slider 12 is penetrated by the moving column 13, and the moving column 13 is inside the slider 12. The upper surface of the slider 12 is fixed to the bottom of the end of the connecting rod 18 near the auxiliary plate 20, and the end of the connecting rod 18 away from the slider 12 is fixed to the upper surface of the functional plate 3. A second groove 14 is provided on the outer surface of the slider 12 near the gear 10. The second groove 14 extends through the interior of the slider 12 to the surface of the moving column 13. The inner wall of the second groove 14 is slidably connected to the outer wall of the first cylinder 15 without gaps to avoid displacement during movement. The end of the first cylinder 15 located inside the second groove 14 is fixed to the surface of the moving column 13. The side of the auxiliary plate 20 near the slider 12 is fixed to the surface of the first inclined plate 16 and the second inclined plate 17.

[0039] Initially, gear 10 is located at the top of rack 11 and is not engaged with rack 11. Scraper 5 is in contact with the coating surface of functional plate 3 via torsion spring 6. Slider 12 is located at the bottom of limiting groove 19. First cylinder 15 is located at the bottom of the inclined surface of first inclined plate 16. When functional plate 3 moves upward, it drives connecting rod 18 to move. When connecting rod 18 moves, it drives slider 12 to slide upward inside limiting groove 19. When slider 12 moves, it drives rack 11 to move upward via moving column 13. When rack 11 moves, it engages with gear 10 and drives gear 10 to rotate. The rotation of gear 10 drives scraper 5 to rotate and move away from the coating surface of functional plate 3. When slider 12 moves to the top of limiting groove 19, rack 11 is not engaged with gear 10, and scraper 5... The torsion spring 6 rotates and re-attaches to the surface of the functional plate 3. At this time, the functional plate 3 is in the position after moving upward. The scraper 5 is attached to the bottom of the coating surface of the functional plate 3. Since the first inclined plate 16 and the second inclined plate 17 are symmetrically arranged, the second inclined plate 17 and the first inclined plate 16 have the same size, and the second inclined plate 17 is located at a position rotated 180 degrees about the center of the second inclined plate 17 and the first inclined plate 16. When the slider 12 is located at the top of the limiting groove 19, the first cylinder 15 abuts against the inclined surface of the second inclined plate 17. The movement of the first cylinder 15 drives the rack 11 to move through the moving column 13. The rack 11 is not in the same plane as the gear 10, so that the rack 11 does not mesh with the gear 10 when the functional plate 3 moves downward, avoiding interference with the rack 11 when moving downward.

[0040] Reference Figure 1 , Figure 3The outer surface of the cleaning tank 1 near the auxiliary plate 20 is fixed to the surface of the limiting shell 21. The interior of the limiting shell 21 is connected to the interior of the first sliding groove 2. The inner wall of the limiting shell 21 is slidably connected to the outer wall of the moving plate 22 without gaps to avoid instability during movement. The surface of the moving plate 22 is provided with an inclined groove 23 that penetrates the interior of the moving plate 22. The inner wall of the inclined groove 23 slides against the outer wall of the second cylinder 24. The end of the second cylinder 24 away from the inclined groove 23 is fixed to the surface of the functional plate 3 located inside the first sliding groove 2. The outer surface of the movable plate 22 is fixed to the surface of the second connecting rod 25, which penetrates the interior of the limiting shell 21. The surface of the second connecting rod 25 is fixed to the surface of the push plate 26. The push plate 26 is located at the end of the second connecting rod 25 away from the limiting shell 21. The bottom end of the push plate 26 is located inside the cleaning tank 1. The surface of the push plate 26 is provided with toothed grooves 27, which are distributed in a linear array. The outer surface of the cleaning tank 1 is fixed to the mounting end of the electric push rod 28, and the output end of the electric push rod 28 is fixed to one side of the top of the push plate 26.

[0041] When using the cleaning tank 1, the staff needs to hang the hanger with the metal parts inside the cleaning tank 1. The hanger is inserted into the toothed groove 27 according to its position. The staff then activates the electric push rod 28, which drives the push plate 26 and the connecting rod 25 to move. When the connecting rod 25 moves, it causes the moving plate 22 to slide inside the limiting shell 21. When the moving plate 22 moves, it causes the second cylinder 24 to move up and down through the inclined groove 23. When the second cylinder 24 moves, it causes the functional plate 3 to move up and down, thereby scraping off the grease on the surface of the functional plate 3. When the push plate 26 moves, it causes the hanger to shake, which, in conjunction with the ultrasonic waves, allows the grease to quickly detach from the surface of the workpiece.

[0042] Among them, the electric actuator 28, the cleaning tank 1, and the negative pressure suction device are all existing technologies, and their structural principles will not be described in detail. The electric actuator 28 adopts the Thomson Electrak XD model, the negative pressure suction device can adopt the Busch Mink MM1202AD model, and the cleaning tank 1 can use the Binensin ultrasonic cleaner B8510E-MTH model. When using it, a thickened plate needs to be bolted to one side. No modification is required to the original product; only the thickened plate needs to be modified. The thickened plate is used to open the first sliding groove 2 so that the functional plate 3 can be used inside the cleaning tank 1. All components of this device are connected by bolts through standard mounting brackets, which facilitates assembly and maintenance.

[0043] The system circuit and startup logic are as follows: 220V AC power is stepped down and rectified to 24V DC power to supply the control circuit. The ultrasonic cleaner is directly connected to the 220V power supply and generates cavitation effect through high-frequency vibration. The electric actuator 28 is connected to the controller through a five-wire potentiometer interface to realize displacement feedback and forward / reverse control. The negative pressure suction pump is controlled by a relay. The pressure relay monitors the negative pressure value, and automatically stops the machine or manually controls the solenoid valve to open and close when the set value is reached. During startup, the ultrasonic cleaner is turned on first. After the cavitation effect stabilizes, the electric actuator 28 is started to drive the bracket to shake. The negative pressure pump automatically maintains the adsorption pressure according to the negative pressure feedback, or can be manually controlled by a button.

[0044] In this device, the torsion spring 6 primarily uses torque to represent its elastic effect, and its calculation formula is usually based on the spring's stiffness (elastic coefficient). The basic formula is: M = K·θ, where: M is the torque generated by the torsion spring 6 upon recovery (the unit is usually N·m or lb·ft); θ is the torsion angle (in radians); and K is the stiffness of the torsion spring 6, representing the restoring torque generated per unit angle. For a standard circular cross-section torsion spring 6, the formula for calculating the stiffness K is:

[0045] K = (G·d) 4 ) / (10.8·D·n) where: G is the shear modulus of the material (usually in N / m) 2 (or psi); d is the diameter of the torsion spring 6 wire; D is the average diameter of the torsion spring 6; n is the effective number of coils; the constant 10.8 is an empirical coefficient used to correct the mechanical distribution in actual use (this value may vary slightly under different designs and standards).

[0046] The implementation principle of the electrophoretic pretreatment tank with ultrasonic cleaning function in this embodiment is as follows: the pusher 26 is moved by the start of the electric pusher 28, and the pusher 26 and the toothed groove 27 drive the hanger to shake, thereby destroying the static boundary layer on the surface of the workpiece and improving the contact efficiency of ultrasonic cavitation bubbles. It is especially effective for cleaning deep holes / blind holes, and allows grease to quickly leave the surface of the workpiece. By setting the Teflon-coated functional plate 3, the grease is adsorbed by the functional plate 3 through liquid shaking.

[0047] When the push plate 26 moves, it drives the moving plate 22 to move horizontally through the connecting rod 25. The horizontal displacement is converted into the vertical movement of the functional plate 3 through the inclined groove 23, which in turn drives the rack 11 to drive the gear 10 to rotate. This ensures that when the functional plate 3 moves upward, the scraper 5 does not contact the functional plate 3. When the functional plate 3 moves downward, the scraper 5 scrapes off the grease and impurities by adhering to the surface of the functional plate 3. The scraper 5 reciprocates and scrapes the oil in conjunction with the torsion spring 6. No additional power source is required throughout the process. The rack 11 is equipped with a first inclined plate 16 and a second inclined plate 17 at its upper and lower ends. When the oil scraping stroke ends, the second inclined plate 17 moves the rack 11 and the gear 10 to a different plane through the first cylinder 15 to avoid interference with the rack 11 when it moves downward. This ensures that the scraper 5 and the functional plate 3 are in contact when it moves downward. The first inclined plate 16 ensures that the rack 11 and the gear 10 re-engage after the rack 11 is reset, forming an automated cycle.

[0048] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
