Description

Technical Field

[0001] The utility model relates to the technical field of vehicle painting, in particular to an automatic liquid replenishing device for an automobile electrophoretic painting pool. Background Art

[0002] Electrophoretic coating is a coating method that uses an external electric field to cause particles such as pigments and resins suspended in the electrophoretic liquid to migrate in a directional manner and deposit on the surface of a substrate at one of the electrodes. Electrophoretic coating is generally the first coating method for automobile body-in-white. The electrophoretic paint film has the advantages of full, uniform, flat and smooth coating. The hardness, adhesion, corrosion resistance, impact performance and penetration performance of the electrophoretic paint film are significantly better than other coating processes.

[0003] In the automotive industry, when a vehicle enters the electrophoretic coating tank for electrophoretic coating, as the vehicle and its fixing bracket enter, the internal solution level will first rise. Too high a liquid level will cause excessive infiltration on the surface of the fixing bracket, resulting in solution waste. After electrophoretic coating, the liquid level will drop, resulting in the inability to completely coat the subsequent processed car body. Therefore, it is necessary to keep the internal liquid level of the electrophoretic coating tank in a relatively stable state at all times, and the solution will produce precipitation and stratification after standing for a long time. The internal solution needs to be kept in a uniformly mixed state. Mixing will cause waves inside, and large waves will affect the liquid level judgment and coating effect. Utility Model Content

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0026] like Figure 1-6 An automatic liquid replenishing device for an automobile electrophoretic coating pool is shown, comprising an electrophoretic pool assembly 1 and a reflux assembly 2, wherein the reflux assembly 2 is arranged on both sides of the electrophoretic pool assembly 1, and the electrophoretic pool assembly 1 comprises an electrophoretic pool 11, a reflux groove 12, a reflux pipe 13, an overflow hole 14, an isolation plate 15, an oil cylinder 16, a mixing plate 17 and a wave-breaking plate 18, wherein the reflux groove 12 is fixedly arranged at the top of both sides of the electrophoretic pool 11, the reflux pipe 13 is fixedly arranged at the bottom of one end of the reflux groove 12, the overflow hole 14 is opened at the top of both sides of the electrophoretic pool 11 and is located on the inner side of the bottom of the reflux groove 12, the isolation plate 15 is fixedly arranged on the inner side of the electrophoretic pool 11, the oil cylinder 16 is fixedly arranged at the bottom of the electrophoretic pool 11, the mixing plate 17 is fixedly arranged at the telescopic end of the oil cylinder 16, and the wave-breaking plate 18 is fixedly arranged inside the two ends of the electrophoretic pool 11.

[0027] Specifically, the reflux assembly 2 includes a collection box 21, a pump 22, a suction pipe 23, an output pipe 24 and a guide cover 25. The pump 22 is fixedly arranged on the top of the collection box 21, the suction pipe 23 is connected to the liquid inlet end of the pump 22, the output pipe 24 is connected to the liquid outlet end of the pump 22, and the guide cover 25 is sleeved on the end of the output pipe 24. The bottom of the reflux groove 12 is inclined downward, and the reflux pipe 13 is fixedly arranged at the lowest end of the bottom of the reflux groove 12. The bottom of the reflux pipe 13 passes through and extends to the collection box 21. On the inner side of the top of the box 21, a card hole that cooperates with the bottom of the return pipe 13 is opened on the top of the collection box 21. The vertical section of the deflector 25 is a 7-shaped structure, one end of which is located on the top of one side of the electrothermal pool 11. The deflector 25 is made of rubber. The telescopic end of the cylinder 16 passes through and extends to the bottom inner side of the electrothermal pool 11. The mixing plate 17 is located on the bottom outer side of the isolation plate 15. The surface of the isolation plate 15 is provided with flow holes. The wave-breaking plates 18 increase in height from the inside to the outside, and the surface of the wave-breaking plates 18 is provided with blocking holes.

[0028] In this embodiment, the electrophoretic coating solution is injected into the electrophoretic tank 11, and the liquid level is located at the bottom of the overflow hole 14. A corresponding liquid level sensor is provided. When the bracket fixes the automobile body-in-white and immerses it into the electrophoretic tank 11, the liquid level rises as the body-in-white is immersed. The excess solution overflows from the overflow hole 14 into the reflux groove 12, and flows rapidly downward along the slope at the bottom of the reflux groove 12, and flows from the reflux pipe 13 to the inside of the collection box 21. After the body-in-white is electrophoretically coated, it is taken out of the solution. At this time, the liquid level will drop rapidly. The liquid level sensor controls the pump 22 to start, and the solution in the collection box 21 is quickly extracted and injected into the electrophoretic tank 11 to achieve automatic liquid replenishment. The suction pipe 23 sucks the solution from the collection box 21 and then inputs it into the electrophoretic tank 11 from the output pipe 24. The guide cover 25 set at the end of the output pipe 24 is made of rubber material to prevent the protruding output pipe 24 from colliding with the body-in-white and causing damage to the body, and to play a diversion effect to reduce splashing.

[0029] Furthermore, an oil cylinder 16 is installed at the bottom of the electrostatic pool 11. The expansion and contraction of the oil cylinder 16 drives the mixing plate 17 to make a reciprocating motion, so that the internal solution is mixed at all times to avoid precipitation. The isolation plate 15 blocks the mixing plate 17 to achieve the effect of protecting the white body. The flow holes on its surface are relatively large, which effectively ensures the mixing effect. Due to the reciprocating motion of the mixing plate 17 and the immersion and removal of the body, large waves will be generated inside. The waves will have a great impact on the liquid level judgment. Therefore, it is necessary to fix wave-breaking plates 18 inside both ends of the electrostatic pool 11. The wave-breaking plates 18 gradually increase from the inside to the outside, and blocking holes are provided on their surface to effectively reduce the wave height, thereby reducing the liquid level fluctuations, which is convenient for the liquid level sensor to automatically judge.

[0030] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0031] In the description of the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "set", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
