Description

Technical Field

[0001] This utility model relates to the field of automotive electrophoretic coating technology, and in particular to an automatic liquid replenishment device for automotive electrophoretic coating tanks. Background Technology

[0002] The automatic replenishment device for automotive electrophoretic coating tanks is a key piece of equipment in automotive coating production lines, used to automatically maintain the stability of the electrophoretic coating tank solution level, composition, and quality. Its core function is to ensure the continuity and consistency of the coating process through sensor monitoring, automated control, and precise replenishment technology. A level sensor monitors the tank solution level in real time; when the level falls below a set value, it automatically replenishes the solution, preventing coating defects caused by level fluctuations, such as uneven film thickness and reduced penetration. The sensor also monitors the liquid level in real time; when it falls below the lower limit, it triggers a PLC to start the replenishment pump. A flow meter measures the replenishment volume, and the pump automatically stops once the set value is reached.

[0003] Existing replenishment devices cause sedimentation and stratification of the solution after prolonged standing. It is necessary to keep the internal solution in a uniformly mixed state. Mixing will cause internal waves, and large waves will affect the liquid level judgment and coating effect.

[0004] An existing patent (publication number: CN222313352U) discloses an automatic liquid replenishment device for an automotive electrophoretic coating tank, which includes an electrophoretic tank assembly and a reflux assembly. The reflux assembly is disposed on both sides of the electrophoretic tank assembly. The electrophoretic tank assembly includes an electrophoretic tank, a reflux tank, a reflux pipe, an overflow hole, a partition plate, a hydraulic cylinder, a mixing plate, and a wave-damping plate. The reflux tank is fixedly disposed on the top of both sides of the electrophoretic tank, and the reflux pipe is fixedly disposed at the bottom of one end of the reflux tank. It recovers the overflowing solution when the car body-in-white is immersed in the tank controlled by the bracket, and quickly replenishes the internal solution of the electrophoretic tank as the car body-in-white is removed, so as to maintain a relatively constant liquid level inside the electrophoretic tank. The operation of the internal mixing plate ensures that the solution does not precipitate, and the wave-damping plates at both ends of the electrophoretic tank reduce wave generation, thereby reducing the impact on liquid level sensing.

[0005] To address the aforementioned issues, existing patents offer solutions that recover overflowing solution when the car body-in-white is immersed in the pool using a support, and reduce wave generation by using wave-damping plates at both ends of the electric pool, thereby minimizing the impact on liquid level sensing. However, these solutions require additional mechanisms to drive the agitation of the solution, resulting in higher overall costs and lower practicality. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic replenishment device for an automotive electrophoretic coating tank. A delivery pump extracts the solution stored in the storage tank and delivers it to the electrophoretic coating tank via a delivery pipe, achieving automatic replenishment. As the solution passes through the connector, it drives the impeller to rotate, causing the connecting rod to rotate, which in turn drives the mounting rod to rotate. The stirring blades stir the solution within the electrophoretic coating tank, effectively reducing sedimentation. No additional stirring mechanism is required, improving practicality and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic replenishment device for an automotive electrophoretic coating tank, comprising an electrophoretic pool body, a liquid storage tank fixed on the lower surface of the electrophoretic pool body, a conveying mechanism for conveying the solution on one side of the liquid storage tank, and an elimination mechanism for eliminating water waves inside the electrophoretic pool body;

[0008] The conveying mechanism includes a conveying pump, which is connected to one side of the liquid storage tank via a pipeline. The output end of the conveying pump is connected to a conveying pipe, and the end of the conveying pipe is connected to a connector. A water impeller is rotatably connected inside the connector.

[0009] Preferably, a connecting rod is welded to one side of the water impeller, and the end of the connecting rod is fixed to an installation rod through the inner wall of the electric pool body.

[0010] Preferably, a plurality of stirring blades are welded at equal intervals on the outer surface of the mounting rod, and one side of the connector is connected to a connecting pipe that communicates with the electric pool body.

[0012] Preferably, two liquid level sensors are fixed to the inner wall of the electric pool body by screws, and a partition plate is welded horizontally inside the electric pool body.

[0013] Preferably, the elimination mechanism includes two mounting plates, both of which are vertically installed inside the electric pool body, and several wave-damping plates are fixed to the side walls of both mounting plates.

[0014] Preferably, both ends of the two mounting plates are fixed with connecting blocks, one side of the connecting block is inserted into a connecting groove opened on the electric pool body, and the side wall of the electric pool body is equipped with fixing bolts that abut against the connecting blocks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the set conveying mechanism, the conveying pump draws out the solution stored in the storage tank and sends it to the electric pool body through the conveying pipe to realize the function of automatic liquid replenishment. When the solution passes through the connecting part, it will drive the water impeller to rotate, drive the connecting rod to rotate, and cause the installation rod to rotate.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An automatic replenishment device for an automotive electrophoretic coating tank includes an electrophoretic pool body 1, a liquid storage tank 2 fixed on the lower surface of the electrophoretic pool body 1, a conveying mechanism for conveying the solution on one side of the liquid storage tank 2, and an elimination mechanism for eliminating water waves inside the electrophoretic pool body 1.

[0028] The conveying mechanism includes a conveying pump 3, which is connected to one side of the liquid storage tank 2 via a pipeline. The output end of the conveying pump 3 is connected to a conveying pipe 31, and the end of the conveying pipe 31 is connected to a connector 32. A water impeller 33 is rotatably connected inside the connector 32. A connecting rod 34 is welded to one side of the water impeller 33. The end of the connecting rod 34 passes through the inner wall of the electric pool body 1 and is fixed to an installation rod 35. Several stirring blades 36 are welded at equal intervals on the outer surface of the installation rod 35. A connecting pipe 37 that communicates with the electric pool body 1 is connected to one side of the connector 32. Both sides of the electric pool body 1 are connected to return pipes 4 that communicate with the liquid storage tank 2.

[0029] By adopting the above technical solution, before using the automatic replenishment device for automotive electrophoretic coating tanks, the electrophoretic tank body 1 and the storage tank body 2 are first assembled in a suitable position. During use, external equipment transports the car frame, immersing it into the electrophoretic tank body 1. At this time, the solution level inside the electrophoretic tank body 1 rises. The solution level can be detected by the level sensor 5. When the level reaches the highest level, with the cooperation of the return pipe 4, the solution can flow through the return pipe 4 into the storage tank body 2 for collection, thereby effectively reducing the possibility of solution leakage. The partition plate 6 can play a separating role, thereby reducing the contact between the car frame and the bottom mechanism. When the car frame is removed, the liquid level in the electrostatic precipitator 1 drops. The liquid level sensor 5 detects this and sends the data to the PLC controller via wires. When the liquid level is detected to be too low, the PLC controller starts the delivery pump 3 to extract the solution stored in the storage tank 2, deliver it through the delivery pipe 31 to the connector 32, and then through the connecting pipe 37 into the electrostatic precipitator 1, thus achieving automatic liquid replenishment. As the solution passes through the connector 32, it drives the impeller 33 to rotate, which in turn drives the connecting rod 34 to rotate, causing the mounting rod 35 to rotate. The stirring blade 36 stirs the solution in the electrostatic precipitator 1, effectively reducing sedimentation and eliminating the need for additional stirring mechanisms, thus improving practicality.

[0030] Specifically, such as Figures 1-4 As shown, two liquid level sensors 5 are fixed to the inner wall of the electric pool body 1 by screws. A partition plate 6 is welded horizontally inside the electric pool body 1. The elimination mechanism includes a mounting plate 7. There are two mounting plates 7. Both mounting plates 7 are installed vertically inside the electric pool body 1. Several wave-damping plates 71 are fixed to the side walls of both mounting plates 7. Connecting blocks 72 are fixed to both ends of both mounting plates 7. A connecting groove 73 opened on the electric pool body 1 is inserted into one side of the connecting block 72. Fixing bolts 74 that abut against the connecting block 72 are installed on the side wall of the electric pool body 1.

[0031] By adopting the above technical solution, the wave-damping plate 71 provided on the mounting plate 7 can reduce the water waves generated when the car frame is placed in or removed. Furthermore, by unscrewing the fixing bolts 74 through the connecting block 72 provided on the mounting plate 7, and with the cooperation of the connecting groove 73, the mounting plate 7 can be disassembled, thereby facilitating the maintenance or replacement of the mounting plate 7.

[0032] Working principle: The liquid level sensor 5 detects the liquid level of the solution. When the liquid level rises to the highest level, with the cooperation of the return pipe 4, the solution can flow through the return pipe 4 into the storage tank 2 for collection, thereby effectively reducing the possibility of solution leakage. The partition plate 6 can separate the components, thereby reducing contact between the car frame and the bottom mechanism. When the car frame is removed, the liquid level in the electrostatic precipitator 1 drops. The liquid level sensor 5 detects the liquid level and sends the data to the PLC controller through wires. When the liquid level is detected to be too low, the PLC controller starts the delivery pump 3 to extract the solution stored in the storage tank 2, send it through the delivery pipe 31 to the connector 32, and then through the connecting pipe 37 into the electrostatic precipitator 1, thereby realizing the function of automatic liquid replenishment. When the solution passes through the connector 32, it drives the impeller 33 to rotate, which in turn drives the connecting rod 34 to rotate, causing the mounting rod 35 to rotate. The stirring blade 36 stirs the solution in the electric pool body 1, effectively reducing the occurrence of sedimentation. This eliminates the need for additional stirring mechanisms, improving practicality. The wave-damping plate 71 on the mounting plate 7 reduces water waves generated when the car frame is inserted or removed. Furthermore, by unscrewing the fixing bolt 74 using the connecting block 72 on the mounting plate 7 and engaging the connecting groove 73, the mounting plate 7 can be disassembled.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
