Description

Technical Field

[0001] This invention relates to the field of electrophoresis technology, and in particular to an electrophoretic paint coating equipment for automobile production. Background Technology

[0002] As the defects of conventional spraying become increasingly apparent, electrophoresis is becoming more and more popular. Electrophoresis is one of the most effective methods for coating metal workpieces. Electrophoretic coating is a special coating method in which a conductive workpiece is immersed in a tank filled with a low-concentration electrophoretic coating diluted with water, which serves as the anode or cathode. A corresponding cathode or anode is also set in the tank. After a direct current is applied between the two electrodes for a period of time, a uniform, fine, and water-insoluble coating film is deposited on the surface of the workpiece.

[0003] During the electrophoretic coating process, the air above the electrophoretic tank contains oil mist, paint mist, and contaminants containing organosilicon substances. These contaminants adhere to the materials to be electrophoretically coated and enter the electrophoretic tank along with the materials, causing contamination of the electrophoretic solution inside the tank. At the same time, as the materials move within the electrophoretic solution, substances from the nearby solution adhere to the material surface, and residual impurities from inside the electrophoretic tank also adhere to the material surface, reducing the quality of the electrophoretic coating.

[0004] Therefore, we propose an electrophoretic coating equipment for automobile production to solve the above problems. Summary of the Invention

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] Firstly, by setting up a paint liquid isolation component in this invention, the movement direction of the material inside the electrophoresis tank is blocked, which can reduce the contact between impurities and contaminants and the material. At the same time, the paint liquid isolation component can directly introduce the filtered electrophoretic liquid into the vicinity of the material and replenish the electrophoretic liquid near the material, preventing the concentration of the electrophoretic liquid near the material from decreasing and improving the quality of electrophoretic coating.

[0035] Secondly, in this invention, the transmission component can drive the first conveyor wheel to rotate, the first conveyor wheel can drive the conveyor belt to rotate, and when the conveyor belt rotates, it can drive the baffle plate to move. The baffle plate can move with the material, and at the same time, the baffle plate can block the movement direction of the material, preventing impurities in the electrophoresis liquid of the electrophoresis tank body from contacting the material, thereby improving the electrophoretic coating quality of the material inside the electrophoresis tank body.

[0036] Thirdly, in this invention, when the baffle plate moves together with the material, the baffle plate can be equipped with a nozzle on its outer wall. The nozzle can guide the filtered electrophoretic liquid to the vicinity of the material, so that the concentration of the electrophoretic liquid near the material will not decrease, thereby improving the electrophoretic liquid coating effect.

[0037] Fourthly, in this invention, while the baffle plate is moving, it will stir the original electrophoretic liquid inside the electrophoresis tank body, thereby improving the mixing degree of the electrophoretic liquid inside the electrophoresis tank body.

[0038] Fifth, in this invention, when the inner side of the conveyor belt is in contact with the first conveyor wheel, the liquid guide block extending from the outer ring of the first conveyor wheel will be stuck in the liquid inlet hole on the inner side of the conveyor belt. The liquid guide block is connected to the liquid inlet hole, which increases the connection effect between the first conveyor wheel and the conveyor belt and prevents the conveyor belt from slipping outside the first conveyor wheel.

[0039] Sixth, in this invention, a sealing plate is provided on the inner side of the liquid inlet hole. Under the action of the second spring, the sealing plate will adhere to the inner side of the liquid inlet hole, blocking the inner side of the liquid inlet hole, preventing the electrophoretic liquid inside the liquid guiding cavity from leaking and failing to enter all the flow baffles, thereby improving the flow effect of the electrophoretic liquid.

[0050] 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.

[0051] In this embodiment of the invention, an electrophoretic coating equipment for automobile production is provided. Please refer to [link to relevant documentation]. Figure 1 - Figure 9 The system includes an electrophoresis tank body 1, with a support frame 2 disposed above the electrophoresis tank body 1. The system is characterized by further including a paint liquid isolation component 6, which is disposed inside the electrophoresis tank body 1. The paint liquid isolation component 6 can reduce the adhesion of impurities inside the electrophoresis tank body 1 to the material and can also replenish new electrophoresis liquid to the vicinity of the material, thereby improving the quality of the electrophoretic coating of the material.

[0052] The material conveying assembly is located below the support frame 2. The material conveying assembly is used for material conveying. The material is conveyed into the electrophoresis tank body 1 through the material conveying assembly, and then processed by the electrophoresis liquid inside the electrophoresis tank body 1.

[0053] The circulation component is located on the outside of the electrophoresis tank body 1. The circulation component is used for circulating the electrophoresis liquid and can also filter the electrophoresis liquid inside the electrophoresis tank body 1 to reduce impurities in the electrophoresis liquid inside the electrophoresis tank body 1.

[0054] The paint isolation assembly 6 includes a first conveyor wheel 605 and a second conveyor wheel 610. The first conveyor wheel 605 and the second conveyor wheel 610 are rotatably disposed inside the electrophoresis tank body 1. A conveyor belt 601 is sleeved on the outside of the first conveyor wheel 605 and the second conveyor wheel 610. The outer ring of the conveyor belt 601 is provided with evenly distributed fixing rods 602. One end of the fixing rod 602 is fixed with a fixing strip 603. A flow-blocking plate 604 is fixed on the outer wall of the fixing strip 603.

[0055] Conveyor wheel 605 and conveyor wheel 610 drive the conveyor belt 601. The conveyor belt 601 drives the fixed rod 602, fixed bar 603 and baffle plate 604 to move, so that the baffle plate 604 separates different materials. When the materials move, it can reduce the adhesion of impurities in the electrophoresis liquid inside the electrophoresis tank body 1 to the materials, thereby improving the quality of electrophoretic coating.

[0056] A liquid guide rod 606 is fixed at the center of the conveyor wheel 605. A transmission gear 609 is rotatably connected to the end of the liquid guide rod 606 away from the conveyor wheel 605. The conveyor wheel 605 has one liquid guide cavity 612 and several liquid guide cavities 615 inside. The liquid guide cavity 612 communicates with the interior of each liquid guide cavity 615. The outlets of the liquid guide cavities 615 are evenly distributed around the conveyor wheel 605. A liquid guide block 611 is installed inside the outlet of each liquid guide cavity 615. A spring 614 is fitted around the outside of the liquid guide block 611. A liquid guide hole 613 is opened on the outside of the liquid guide block 611, and the interior of the liquid guide block 611 is hollow. The end of the liquid guide block 611 extending from the liquid guide cavity 615 is open. The spring 614 controls the liquid guide block 611. When the liquid guide block 611 enters the liquid inlet 608, the spring 614 controls the liquid guide block 611 so that the liquid guide hole 613 on the outer wall of the liquid guide block 611 can fit against the inner wall of the liquid guide cavity 615. At this time, the liquid guide hole 613 is blocked and cannot transport the electrophoresis liquid. The electrophoresis liquid can flow through the liquid guide hole 613 on the squeezed liquid guide block 611. The inner shape of the opening of the liquid guide cavity 615 matches the outer shape of the liquid guide block 611. The inner width of the liquid guide cavity 615 is greater than the outer diameter of the liquid guide block 611. When the liquid guide block 611 is squeezed, the liquid guide hole 613 on the outer wall of the liquid guide block 611 can move to a wider position inside the liquid guide cavity 615, so that the electrophoresis liquid can enter the liquid guide hole 613.

[0057] The first conveyor wheel 605 drives the conveyor belt 601. The first conveyor wheel 605 has a liquid guiding cavity 612 and a second liquid guiding cavity 615 inside. The filtered electrophoresis liquid is guided through the first liquid guiding cavity 612 and the second liquid guiding cavity 615. The electrophoresis liquid inside the second liquid guiding cavity 615 can enter the conveyor belt 601 through the liquid guiding hole 613 on the outer wall of the liquid guiding block 611, which plays the role of transporting the electrophoresis liquid.

[0058] The transmission gear 609 is connected to the transmission assembly 5, which includes a transmission box 501. The transmission box 501 is fixed to the outside of the electrophoresis tank body 1, and a motor 502 is provided on the outer wall of the transmission box 501. The motor 502 is connected to the transmission gear 609 through gears.

[0059] The transmission assembly 5 controls the first conveyor wheel 605. The motor 502 drives the transmission gear 609 to rotate, which in turn drives the first conveyor wheel 605 to rotate. This causes the first conveyor wheel 605 to rotate, which in turn drives the conveyor belt 601 to rotate. The conveyor belt 601 then drives the baffle plate 604 to move, allowing the baffle plate 604 to move along with the material.

[0060] The conveyor belt 601 has a liquid guiding cavity 618 inside, and the inner side of the conveyor belt 601 has evenly distributed liquid inlet holes 608. The liquid inlet hole 608 has an annular protrusion, and a sealing plate 616 is provided at one end of the protrusion. A spring 617 is sleeved on the outside of the sealing plate 616, and one end of the spring 617 is fixed to the inner wall of the liquid guiding cavity 618.

[0061] The liquid inlet 608 on the inner side of the conveyor belt 601 can be connected to the liquid guide block 611. The liquid guide block 611 can guide the electrophoresis liquid into the liquid guide cavity 618. The liquid guide cavity 618 guides the electrophoresis liquid into the fixed rod 602, the fixed strip 603 and the baffle plate 604. At the same time, a sealing plate 616 is provided on the inner side of the liquid inlet 608. Under the action of the spring 617, the sealing plate 616 can block the liquid inlet 608. In this way, the liquid inlet 608 that is not connected to the liquid guide block 611 will not leak electrophoresis liquid, so that the electrophoresis liquid in the liquid guide cavity 618 can enter the fixed rod 602.

[0062] The inner diameter of the liquid inlet 608 is larger than the outer diameter of the liquid guide block 611, and the liquid guide block 611 has notches around the end that extends from the inside of the liquid guide cavity 615.

[0063] The inlet hole 608 serves to accommodate the liquid guide block 611. At the same time, the liquid guide block 611 has a notch on the end of its extension from the liquid guide cavity 615. When one end of the liquid guide block 611 enters the inlet hole 608 and squeezes the sealing sheet 616, the electrophoretic liquid inside the liquid guide block 611 can enter the sealing sheet 616 through the notch. Meanwhile, the sealing sheet 616 is provided with a top block 619, which is slidably disposed in the inlet hole 608. The top block 619 will be squeezed first, and at this time, the electrophoretic liquid near the sealing sheet 616 can enter the liquid guide cavity 618 through the gap between the top blocks 619.

[0064] The interiors of the fixing rod 602, fixing strip 603, and baffle plate 604 are all hollow. The interiors of the fixing rod 602, fixing strip 603, and baffle plate 604 are connected. The outer wall of the baffle plate 604 has evenly distributed through holes. A nozzle 607 is provided on the outside of the through holes of the baffle plate 604. The fixing rod 602 is connected to the interior of the conveyor belt 601.

[0065] The baffle plate 604 can move with the material. The electrophoretic liquid inside the liquid guiding chamber 618 can be conveyed through the fixed rod 602, the fixed bar 603 and the baffle plate 604. The electrophoretic liquid inside the baffle plate 604 can be sprayed to the vicinity of the material through the nozzle 607 to convey the electrophoretic liquid near the material.

[0066] The inner wall of the electrophoresis tank body 1 is fixed with symmetrically distributed positioning strips 15. The positioning strips 15 are set on the moving path of the fixed strip 603. The two positioning strips 15 are symmetrically distributed about the center line of the fixed strip 603. The two ends of the fixed strip 603 are provided with grooves, and ball bearings are provided in the grooves at both ends of the fixed strip 603.

[0067] The ball bearings on both sides of the fixing strip 603 can fit against the positioning strip 15. The ball bearings reduce the friction at both ends of the fixing strip 603 and improve the movement effect of the fixing strip 603. At the same time, the positioning strip 15 is fixed to the inner wall of the electrophoresis tank body 1 to prevent the inner wall of the electrophoresis tank body 1 from being damaged by friction.

[0068] The outer wall of the electrophoresis tank body 1 is provided with a uniformly distributed main body reinforcement frame 12, and the outside of the main body reinforcement frame 12 is "U" shaped.

[0069] The main reinforcement frame 12 serves to reinforce the main body 1 of the electrophoresis tank and improve its strength.

[0070] The outer wall of the electrophoresis tank body 1 is provided with a hollow side box 10. The interior of the side box 10 is connected to the interior of the electrophoresis tank body 1. Electrode rods 11 are installed inside the side box 10. The side box 10 and the main body reinforcement frame 12 are staggered.

[0071] The side box 10 serves to accommodate the electrode rods 11, through which current is fed into the electrophoresis tank body 1 to power the materials inside the electrophoresis tank body 1 for electrophoretic coating.

[0072] The material conveying assembly includes a guide rail 3, and a sliding suspension assembly 4 is provided below the guide rail 3.

[0073] The guide rail 3 is used to control the movement of the suspension assembly 4 and prevent the suspension assembly 4 from tilting.

[0074] The suspension assembly 4 includes several convex sliding seats 401 and hinge blocks 402. The T-shaped ends of the sliding seats 401 are slidably disposed inside the guide rail 3. The sliding seats 401 are connected to each other by hinges composed of several hinge blocks 402. The lower end of the sliding seat 401 is provided with a material suspension rod 403.

[0075] The T-shaped end of the sliding seat 401 can be locked in the groove opened at the bottom of the guide rail 3. Multiple sliding seats 401 are connected by hinge blocks 402. All sliding seats 401 are connected together by hinge blocks 402. The material suspension rod 403 below the sliding seat 401 plays the role of fixing the material. The suspension assembly 4 brings the material into the electrophoresis tank body 1.

[0076] The circulation assembly includes a filter assembly 9, a delivery pump 8 is provided on the outer wall of the filter assembly 9, the output end of the delivery pump 8 is connected to a conduit 7, the input end of the delivery pump 8 is connected to the filter assembly 9, the other end of the conduit 7 is connected to the paint isolation assembly 6, the input end of the filter assembly 9 is connected to a conduit 13, the other end of the conduit 13 is connected to a liquid guide tank 14, the liquid guide tank 14 is fixed at the bottom of the electrophoresis tank body 1, and the liquid guide tank 14 is connected to the inside of the electrophoresis tank body 1.

[0077] The liquid guide tank 14 is connected to the interior of the electrophoresis tank body 1, allowing the electrophoresis solution inside the electrophoresis tank body 1 to enter the liquid guide tank 14. Simultaneously, the electrophoresis solution in the liquid guide tank 14 can enter the filter assembly 9 through the second conduit 13. The filter assembly 9 filters the electrophoresis solution using a biofilm filtration method to remove particulate dust and oil from the electrophoresis solution. The filtered electrophoresis solution is then transported by the transfer pump 8 to the first conduit 7, which in turn guides the filtered electrophoresis solution into the first liquid guide chamber 612. The electrophoresis solution is then guided through the first liquid guide chamber 612 into the second liquid guide chamber 615, and finally passes through the liquid guide block 611. The liquid guiding chamber 618, the fixing rod 602, and the fixing strip 603 enter the baffle plate 604. The electrophoretic liquid is reintroduced to the vicinity of the material through the nozzle 607 outside the baffle plate 604, replenishing the electrophoretic liquid near the material. The electrophoretic liquid is directly introduced to the vicinity of the material through the material, reducing the contact between the material and the original electrophoretic liquid inside the electrophoretic tank body 1. This avoids impurities in the original electrophoretic liquid inside the electrophoretic tank body 1 coming into contact with the material, improving the coating effect. The guide tube 7 and the liquid guiding rod 606 have a rotating structure. When the liquid guiding rod 606 rotates together with the conveyor wheel 605, the guide tube 7 will not twist, preventing damage to the guide tube 7.

[0078] The working principle of this invention is as follows: The suspension assembly 4 drives the material into the electrophoresis tank body 1, immersing the material in the electrophoresis solution inside the electrophoresis tank body 1. Then, the motor 502 is started, and the motor 502 drives the transmission gear 609 to rotate through the gear. The transmission gear 609 drives the first conveyor wheel 605 to rotate. The liquid guide block 611 extending from the outer ring of the first conveyor wheel 605 can be stuck in the liquid inlet 608 on the inner side of the conveyor belt 601. The first conveyor wheel 605 drives the conveyor belt 601 to rotate, and the conveyor belt 601 drives the baffle plate 604 to move. The baffle plate 604 moves together with the material entering the electrophoresis tank body. The baffle plate 604 blocks the residual impurities in the direction of material movement, preventing impurities from contacting the material.

[0079] During the contact between the conveyor wheel 605 and the inner wall of the conveyor belt 601, the liquid guide block 611 can be stuck in the liquid inlet hole 608. Simultaneously, when one end of the liquid guide block 611 enters the liquid inlet hole 608 and squeezes the sealing plate 616, the electrophoretic liquid inside the liquid guide block 611 can enter the sealing plate 616 through the notch. Meanwhile, the sealing plate 616 is provided with a top block 619, which is slidably disposed within the liquid inlet hole 608. The top block 619 will be squeezed first, at which point the electrophoretic liquid near the sealing plate 616 can enter the liquid guide block through the gap between the top blocks 619. Inside cavity 618, top block 619 moves sealing plate 616, forming a gap between sealing plate 616 and liquid inlet 608. Liquid guide block 611 can guide the filtered electrophoretic liquid into liquid guide cavity 618. Then, the electrophoretic liquid inside liquid guide cavity 618 enters baffle plate 604 through fixing rod 602 and fixing strip 603. The electrophoretic liquid inside baffle plate 604 can be sprayed out through nozzle 607. Nozzle 607 can spray the filtered electrophoretic liquid near the material to avoid the concentration of electrophoretic liquid near the material decrease and improve the quality of electrophoretic coating.

[0080] After the inner side of the conveyor belt 601 separates from the first conveyor wheel 605, the liquid inlet 608 on the inner side of the conveyor belt 601 can be separated from the liquid guide block 611. At the same time, the sealing plate 616 on the inner side of the liquid inlet 608 will not be squeezed by the liquid guide block 611. Under the action of the second spring 617, the sealing plate 616 can block the liquid inlet 608. In this way, the liquid inlet 608 that is not connected to the liquid guide block 611 will not leak electrophoretic liquid, so that the electrophoretic liquid in the third liquid guide cavity 618 can enter the fixed rod 602. In this way, the electrophoretic liquid inside the third liquid guide cavity 618 will not directly leak into the electrophoresis tank body 1.

[0081] When the liquid guide block 611 enters the liquid inlet 608, the liquid guide block 611 and the top block 619 press against each other, and part of the liquid guide block 611 will retract into the liquid guide cavity 615. At this time, the liquid guide hole 613 on the outer wall of the liquid guide block 611 can move to a wider position inside the liquid guide cavity 615, so that the electrophoresis liquid can enter the liquid guide hole 613. When the liquid guide block 611 is separated from the liquid inlet 608, the spring 614 controls the liquid guide block 611 to return to its original position, so that the liquid guide hole 613 on the outer wall of the liquid guide block 611 can fit against the inner wall of the liquid guide cavity 615. At this time, the liquid guide hole 613 is blocked, and the liquid guide hole 613 at this point cannot deliver the electrophoresis liquid. In this way, the liquid guide block 611 separated from the liquid inlet 608 will not leak electrophoresis liquid.

[0082] During the movement of the baffle plate 604, the nozzles 607 on the outer wall of the baffle plate 604 replenish the electrophoretic liquid inside the electrophoretic tank body 1. The baffle plate 604 will stir the electrophoretic liquid inside the electrophoretic tank body 1, improve the mixing degree of the electrophoretic liquid inside the electrophoretic tank body 1, and improve the quality of electrophoretic coating.

[0083] Finally, the current is introduced into the electrophoresis tank body 1 through the electrode rod 11 inside the side box 10, and the material inside the electrophoresis tank body 1 can be electrophoretically coated.

[0084] The electrophoretic solution inside the electrophoresis tank body 1 can enter the liquid guide tank 14. The electrophoretic solution inside the liquid guide tank 14 can enter the filter assembly 9 through the second conduit 13. The electrophoretic solution is filtered by the filter assembly 9. At the same time, the delivery pump 8 introduces the electrophoretic solution into the liquid guide chamber 612 through the first conduit 7 to replenish the electrophoretic solution inside the first delivery wheel 605.

[0085] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
