Description

Technical Field

[0001] This invention belongs to the technical field of electrophoretic coating equipment, specifically a vibration defoaming and high-temperature resistant electrophoretic coating equipment for automobile engine cylinder heads. Background Technology

[0002] Electrophoretic coating is a core process for surface anti-corrosion treatment of automotive parts. Among them, high-temperature resistant electrophoretic coating is widely used in high-temperature components such as engine cylinder heads and gearbox housings due to its excellent temperature resistance and corrosion resistance. Existing electrophoretic coating equipment mainly consists of a conveying system, an electrophoretic tank, a DC power supply system, and a post-processing system. It uses an electric field to cause charged coating particles to be deposited directionally on the surface of the workpiece, forming a uniform and dense protective film.

[0003] In the manufacturing process of automotive engine cylinder heads, electrophoretic coating equipment is used to perform electrophoretic anti-corrosion treatment on the cylinder heads in order to improve their anti-corrosion performance. Due to the complex structure of automotive engine cylinder heads, which are densely packed with deep and narrow cavities such as bolt blind holes, oil and water passages, combustion chamber pits, and valve guide holes, air bubbles are easily trapped in the cavities when immersed in the electrophoretic tank, making it difficult for them to float up and be expelled naturally. Currently, electrophoretic coating equipment only uses fixed ultrasonic bars for defoaming and cannot perform rotational defoaming treatment. As a result, some air bubbles in the cavities cannot rise and be expelled, causing them to remain for a long time and affecting the adhesion of the electrophoretic film. Summary of the Invention

[0007] In the above technical solution, preferably, the elastic pressure member includes a pressure ring sleeved on the trapezoidal rod, one side of the pressure ring is in contact with the surface of the cylinder head mounting sleeve, two movable plates are symmetrically fixedly connected to the movable ring, one side of the movable plate is fixedly connected to the pressure ring, a second spring is fixedly connected to one side of the pressure ring, the second spring is sleeved on the trapezoidal rod, and one end of the second spring is fixedly connected to the inside of the concave plate.

[0008] In the above technical solution, preferably, two guide sleeves are symmetrically fixedly connected to the concave plate, the guide sleeves are sleeved on the movable plate, one end of the first spring is fixedly connected to the inside of the concave plate, and the other end of the first spring is in contact with the surface of the cylinder head mounting sleeve.

[0009] In the above technical solution, preferably, the circulating defoaming component includes a gear pump fixedly connected to the bottom of the motor output shaft. The input end of the gear pump passes through the interior of the electrophoresis tank via a connecting pipe. The output end of the gear pump passes through the interior of the electrophoresis tank and is connected to a water outlet pipe. A drain pipe is sleeved on the water outlet pipe. A reciprocating drive component is provided at one end of the rotating rod.

[0010] In the above technical solution, preferably, the reciprocating drive component includes a commutator fixedly connected to one end of the rotating rod, an eccentric wheel fixedly connected to the output end of the commutator, a sliding sleeve sleeved on the eccentric wheel, one side of the sliding sleeve fixedly connected to the drain pipe via a connecting plate, a support sleeve fixedly connected inside the electrophoresis tank, the top of the commutator fixedly connected inside the support sleeve, the support sleeve sleeved on the rotating rod, two positioning rods symmetrically fixedly connected inside the support sleeve, and the sliding sleeve sleeved on the positioning rods.

[0011] In the above technical solution, preferably, a swing defoaming component is provided on one side of the sliding sleeve. The swing defoaming component includes a side plate fixedly connected to one side of the sliding sleeve, and a round rod fixedly connected to one side of the side plate. A sleeve plate is hinged inside the electrophoresis tank through a shaft, and the sleeve plate is fixedly connected to the ultrasonic vibrating rod.

[0012] In the above technical solution, preferably, a fixing sleeve is fixedly connected inside the electrophoresis tank, the fixing sleeve is fitted onto the side plate, and an arc-shaped plate is fixedly connected inside the electrophoresis tank, the top of the arc-shaped plate being in contact with the bottom of the drain pipe.

[0013] In the above technical solution, preferably, an anti-sway frame is fixedly connected inside the electrophoresis tank, and the anti-sway frame is sleeved on the concave plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a motor and reducer to drive a rotating rod and gears to rotate. The gears, through a gear sleeve and a hexagonal plate, drive the cylinder head mounting sleeve and the automobile engine cylinder head to rotate, allowing air bubbles in each position in the automobile engine cylinder head to rise and be expelled. At the same time, the hexagonal plate drives the collision vibration component to generate periodic collision vibrations on the cylinder head mounting sleeve, causing air bubbles attached to the deep and narrow cavity to quickly detach from the wall. Combined with the ultrasonic cavitation effect, a double defoaming effect is formed, improving the defoaming efficiency and effectively ensuring the density and adhesion of the electrophoretic membrane.

[0015] Furthermore, relying solely on the rotation of the cylinder head mounting sleeve to remove air bubbles results in the detached bubbles easily re-adhering to the workpiece surface, making it difficult to remove them quickly, and the defoaming speed and thoroughness are still insufficient. However, by designing a structure with a gear pump, water outlet pipe, and drain pipe in the circulating defoaming component, the gear pump at the bottom of the motor output shaft draws paint from the electrophoresis tank and sprays it out through the water outlet pipe and drain pipe. The rotating rod drives the drain pipe to move back and forth through the reciprocating drive component, flushing away the air bubbles and accelerating their upward floating and discharge, preventing the air bubbles from re-adhering, and further improving the overall defoaming efficiency.

[0016] Furthermore, fixed ultrasonic vibrating rods have acoustic field dead zones, and defoaming in deep hole areas is still incomplete, resulting in insufficient overall uniformity. However, through the structural design of the side plate, round rod, and sleeve plate in the swing defoaming component, the sliding sleeve moves back and forth, driving the side plate and round rod to move synchronously. The round rod pushes the sleeve plate to swing back and forth around the shaft, and the sleeve plate drives the ultrasonic vibrating rod to swing synchronously, dynamically adjusting the acoustic field distribution, completely eliminating standing wave dead zones, and improving the defoaming effect of deep and narrow cavities.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, this invention provides a vibration defoaming and high-temperature resistant electrophoretic coating equipment for automobile engine cylinder heads, including an electrophoresis tank 1. A suspended conveyor frame 2 and a guide rail 3 are fixedly connected to the electrophoresis tank 1 via a connecting plate. A lifting device 4 is fixedly connected to the suspended conveyor frame 2. A concave plate 5 is fixedly connected to the bottom of the lifting device 4. A cylinder head mounting sleeve 6 is disposed inside the concave plate 5. The equipment also includes: The rotary vibration defoaming component 7 is installed inside the electrophoresis tank 1 to quickly eliminate air bubbles on the tank cover; The rotary vibration defoaming component 7 includes a trapezoidal rod 71 fixedly connected to one side of the cylinder head mounting sleeve 6. One end of the trapezoidal rod 71 extends through to one side of the concave plate 5 and is fixedly connected to a hexagonal plate 72. A toothed sleeve 73 is fixedly connected to one side of the hexagonal plate 72. A transmission component 74 connected to the toothed sleeve 73 is provided on one side of the electrophoresis tank 1. A support rod 75 is fixedly connected to one side of the electrophoresis tank 1. One end of the support rod 75 extends through to the outside of the concave plate 5. A spring 76 located inside the concave plate 5 is sleeved on the support rod 75. A collision vibration component 77 is provided on the hexagonal plate 72. An ultrasonic vibration rod 78 is provided inside the electrophoresis tank 1. The circulating defoaming component 8 is located on one side of the electrophoresis tank 1 and is used to increase the rising and discharging speed of bubbles.

[0021] Specifically, the lifting device 4 includes a cylinder fixedly connected to the suspended conveyor frame 2. A top plate is fixedly connected to the output end of the cylinder. Two square sleeves are fixedly connected to the bottom of the top plate. An outer sleeve is installed inside each square sleeve, and a square plate is slidably connected inside the outer sleeve. The top of the square plate is fixedly connected to the bottom of the suspended conveyor frame 2, and the bottom of the outer sleeve is fixedly connected to a concave plate 5. The cylinder can drive the outer sleeve to rise and fall. After the outer sleeve rises to a certain height, the suspended conveyor frame 2 will move the outer sleeve via the square plate, allowing it to move into the guide rail 3. The guide rail 3 supports the outer sleeve and the concave plate 5, facilitating movement. Proceed to the next process; the cylinder head mounting sleeve 6 has a support column fixedly connected inside. The support column can reduce the contact area between the automobile engine cylinder head and the cylinder head mounting sleeve 6, and improve the electrophoretic anti-corrosion effect. The cylinder head mounting sleeve 6 is fixedly connected with bolt clamping parts, which can clamp and position the automobile engine cylinder head; the lifting device 4 and the cylinder head mounting sleeve 6 are mature technology applications; the bottom of the cylinder head mounting sleeve 6 is fixedly connected with two counterweight plates. The counterweight plates can ensure that the cylinder head mounting sleeve 6 is in a horizontal state. In use, the lifting device 4 drives the concave plate 5 to move down, so that the gear sleeve 73 can stably mesh with the gear 744.

[0022] like Figures 3 to 7 As shown, the transmission component 74 includes a motor 741 fixedly connected to one side of the electrophoresis tank 1. A reducer 742 is fixedly connected to the top of the output shaft of the motor 741. The output end of the reducer 742 extends into the interior of the electrophoresis tank 1 and is fixedly connected to a rotating rod 743. A gear 744 that meshes with the gear sleeve 73 is fixedly connected to the rotating rod 743.

[0023] Specifically, the trapezoidal rod 71 can limit the left side of the cylinder head mounting sleeve 6, and together with the spring 76, it can maintain the stability of the cylinder head mounting sleeve 6; the reducer 742 is a worm gear reducer 742, and one side of the reducer 742 is fixedly connected to the electrophoresis tank 1; in use, the motor 741 drives the rotating rod 743 and the gear 744 to rotate stably after the reducer 742 reduces the speed and increases the torque. The gear 744 meshes precisely with the gear sleeve 73, which can synchronously drive the hexagonal plate 72, the trapezoidal rod 71 and the cylinder head mounting sleeve 6 to rotate at a uniform speed, so that all surfaces of the cylinder head and the deep and narrow cavities are aligned with the ultrasonic vibrating rod 78 in sequence, eliminating the blind zone of ultrasonic action.

[0024] like Figures 4 to 7 As shown, the collision vibration component 77 includes a rotating sleeve 771 sleeved on a hexagonal plate 72. The rotating sleeve 771 has an inclined groove 772. A transverse groove 773 is formed inside the inclined groove 772. A sliding rod 774 is slidably connected inside the transverse groove 773. A movable ring 775 is sleeved on the rotating sleeve 771. One end of the sliding rod 774 is fixedly connected to the inside of the movable ring 775. A limiting ring 776 is fixedly connected to one side of the concave plate 5. The limiting ring 776 is sleeved on the rotating sleeve 771. An elastic pressure component 777 is provided on the movable ring 775.

[0025] Specifically, when the hexagonal plate 72 drives the rotating sleeve 771 to rotate synchronously, the rotating sleeve 771 pushes the sliding rod 774 through the inclined groove 772. The sliding rod 774 compresses the elastic pressure member 777 through the limiting ring 776. When the sliding rod 774 enters the transverse groove 773, the elastic pressure member 777 quickly resets and generates periodic collision vibrations on the cylinder head mounting sleeve 6. Since a spring 76 is provided on one side of the cylinder head mounting sleeve 6, the collision vibration can be accurately transmitted to the automobile engine cylinder head. This structure does not require an additional power source. The vibration frequency is synchronized with the cylinder head rotation frequency, which allows the tightly attached bubbles in the deep and narrow cavity to quickly detach from the wall surface, greatly improving the defoaming efficiency in dead corners.

[0026] like Figures 4 to 7 As shown, the elastic pressure member 777 includes a pressure ring 7771 sleeved on the trapezoidal rod 71. One side of the pressure ring 7771 is in contact with the surface of the cylinder head mounting sleeve 6. Two moving plates 7772 are symmetrically fixedly connected to the moving ring 775. One side of the moving plate 7772 is fixedly connected to the pressure ring 7771. A second spring 7773 is fixedly connected to one side of the pressure ring 7771. The second spring 7773 is sleeved on the trapezoidal rod 71. One end of the second spring 7773 is fixedly connected to the inside of the concave plate 5.

[0027] Specifically, the moving ring 775 drives the pressure ring 7771 to move axially along the trapezoidal rod 71 via the moving plate 7772, compressing the spring 7773 to generate elastic force, achieving elastic collision rather than rigid impact. This structure can ensure sufficient vibration intensity to detach the bubble, while preventing excessive impact energy, ensuring the continuity and stability of the collision vibration, and extending the service life of the equipment.

[0028] like Figures 4 to 6 As shown, two guide sleeves 9 are symmetrically fixedly connected to the concave plate 5. The guide sleeves 9 are sleeved on the movable plate 7772. One end of the spring 76 is fixedly connected to the inside of the concave plate 5, and the other end of the spring 76 is in contact with the surface of the cylinder head mounting sleeve 6.

[0029] Specifically, the guide sleeve 9 is fitted onto the moving plate 7772, which can precisely guide the axial movement of the moving plate 7772, prevent the moving plate 7772 from radially shifting, and ensure that the pressure ring 7771 is subjected to uniform force. Since a spring 76 is provided on one side of the cylinder head mounting sleeve 6, the collision vibration can be accurately transmitted to the automobile engine cylinder head. At the same time, the spring 76 can buffer excess vibration, reduce the transmission to the concave plate 5 and the lifting device 4, and reduce the overall noise of the equipment.

[0030] like Figures 4 to 6 As shown, the circulating defoaming component 8 includes a gear pump 81 fixedly connected to the bottom of the output shaft of the motor 741. The input end of the gear pump 81 passes through the interior of the electrophoresis tank 1 through a connecting pipe. The output end of the gear pump 81 passes through the interior of the electrophoresis tank 1 and is connected to a water outlet pipe 82. A drain pipe 83 is sleeved on the water outlet pipe 82. A reciprocating drive component 84 is provided at one end of the rotating rod 743.

[0031] Specifically, the gear pump 81 at the bottom of the output shaft of the motor 741 draws paint liquid from the electrophoresis tank 1 and sprays it out through the water outlet pipe 82 and the drain pipe 83. The rotating rod 743 drives the drain pipe 83 to move back and forth through the reciprocating drive component 84, flushing away the air bubbles and accelerating their upward discharge, thus preventing the air bubbles from re-adhering and further improving the overall defoaming efficiency.

[0032] like Figures 3 to 5 As shown, the reciprocating drive component 84 includes a commutator 841 fixedly connected to one end of the rotating rod 743. An eccentric wheel 842 is fixedly connected to the output end of the commutator 841. A sliding sleeve 843 is sleeved on the eccentric wheel 842. One side of the sliding sleeve 843 is fixedly connected to the drain pipe 83 through a connecting plate. A support sleeve 844 is fixedly connected inside the electrophoresis tank 1. The top of the commutator 841 is fixedly connected inside the support sleeve 844. The support sleeve 844 is sleeved on the rotating rod 743. Two positioning rods 845 are symmetrically fixedly connected inside the support sleeve 844. The sliding sleeve 843 is sleeved on the positioning rods 845.

[0033] Specifically, the commutator 841 is a bevel gear commutator. The rotating rod 743 changes the transmission direction through the commutator 841, driving the eccentric wheel 842 to rotate, causing the sliding sleeve 843 to reciprocate linearly along the positioning rod 845. This, in turn, drives the drain pipe 83 to reciprocate synchronously through the connecting plate, expanding the coverage of the liquid flow. This allows for the washing of the rotating cylinder head surface of the automobile engine, avoiding liquid flow blind spots, while ensuring uniform liquid flow intensity and improving the consistency of the overall defoaming effect.

[0034] like Figures 2 to 4 As shown, a swing defoaming component 10 is provided on one side of the sliding sleeve 843. The swing defoaming component 10 includes a side plate 101 fixedly connected to one side of the sliding sleeve 843. A round rod 102 is fixedly connected to one side of the side plate 101. A sleeve plate 103 is hinged inside the electrophoresis tank 1 through a shaft. The sleeve plate 103 is fixedly connected to the ultrasonic vibrating rod 78.

[0035] Specifically, when the sliding sleeve 843 reciprocates, it drives the side plate 101 and the round rod 102 to move synchronously. The round rod 102 pushes the sleeve 103 to swing back and forth around the shaft. The sleeve 103 drives the ultrasonic vibrating rod 78 to swing synchronously, dynamically adjusting the sound field distribution, completely eliminating standing wave dead angles, and improving the defoaming effect of deep and narrow cavities.

[0036] like Figures 2 to 4 As shown, a fixing sleeve 11 is fixedly connected inside the electrophoresis tank 1. The fixing sleeve 11 is fitted onto the side plate 101. An arc-shaped plate 12 is fixedly connected inside the electrophoresis tank 1. The top of the arc-shaped plate 12 is in contact with the bottom of the drain pipe 83.

[0037] Specifically, the fixing sleeve 11 is fitted onto the side plate 101, which can precisely guide the reciprocating motion of the side plate 101, prevent the side plate 101 from shifting, ensure the fitting accuracy between the round rod 102 and the sleeve plate 103, and ensure the stability of the swing angle of the ultrasonic vibrating rod 78; the arc plate 12 supports and guides the bottom of the drain pipe 83, preventing the drain pipe 83 from sagging or shaking during reciprocating movement, and ensuring the accuracy of the spray direction.

[0038] like Figures 1 to 3 As shown, an anti-sway frame 13 is fixedly connected inside the electrophoresis tank 1, and the anti-sway frame 13 is sleeved on the concave plate 5.

[0039] Specifically, the anti-sway bracket 13 is installed on the outside of the concave plate 5, which can limit the concave plate 5 and effectively prevent the cylinder head of the car engine from shaking during rotation and collision vibration, which could lead to damage to the lifting device 4.

[0040] Working principle and usage process of this invention: The suspended conveyor 2 moves the lifting device 4 and cylinder head mounting sleeve 6 above the electrophoresis tank 1. The lifting device 4 lowers the cylinder head mounting sleeve 6, so that the gear sleeve 73 meshes with the gear 744, and the automobile engine cylinder head is completely immersed in the paint. The motor 741 starts, and after being reduced in speed and torque by the reducer 742, it drives the rotating rod 743 and the gear 744 to rotate. The gear 744 meshes with the gear sleeve 73, which drives the hexagonal plate 72, the trapezoidal rod 71 and the cylinder head mounting sleeve 6 to rotate synchronously. This allows each surface of the automobile engine cylinder head to be subjected to the cavitation effect of the ultrasonic vibrating rod 78 in sequence. At the same time, the hexagonal plate 72 drives the rotating sleeve 771 to rotate synchronously. The rotating sleeve 771 pushes the sliding rod 774 through the inclined groove 772. The sliding rod 774 and the moving ring 775 compress the spring 7773 through the moving plate 7772 and the limiting ring 776. When the sliding rod 774 enters the transverse groove 773, the pressure ring 7771 quickly resets and generates a collision vibration on the cylinder head mounting sleeve 6, realizing an elastic collision rather than a rigid impact. This allows the bubbles attached to the deep and narrow cavity to quickly detach from the wall surface, and combined with the ultrasonic cavitation effect, forms the first layer of defoaming. The bottom of the output shaft of motor 741 synchronously drives gear pump 81 to run. Gear pump 81 draws paint liquid from electrophoresis tank 1 through connecting pipe and sprays it out in a direction through water outlet pipe 82 and drain pipe 83. Rotary rod 743 drives eccentric wheel 842 to rotate through commutator 841, causing sliding sleeve 843 to move linearly back and forth along positioning rod 845. Then, through connecting plate, it drives drain pipe 83 to move back and forth synchronously, expanding the coverage of liquid flow, quickly flushing away bubbles that have detached from the wall and accelerating their upward floating and discharge, preventing bubbles from re-attaching, and forming a second defoaming process. At the same time, the sliding sleeve 843 drives the side plate 101 and the round rod 102 to move synchronously. The round rod 102 pushes the sleeve 103 to swing back and forth around the shaft. The sleeve 103 drives the ultrasonic vibrating rod 78 to swing synchronously, dynamically adjusting the sound field distribution, completely eliminating the standing wave dead angle, improving the defoaming effect of the deep and narrow cavity, and forming a third defoaming. After defoaming is completed, electrophoretic coating can be carried out. After electrophoretic coating is completed, the lifting device 4 drives the cylinder head mounting sleeve 6 to rise, the gear sleeve 73 disengages from the gear 744, and the suspended conveyor 2 transports the workpiece to the next process.
