[0037] The working process of the utility model discloses a car body electrophoresis mixed line production continuous power failure control system is described below.

[0038] The electrophoretic tank is composed of three parts, and is divided into a coating waiting area, a coating area and a coating buffer area. The coating waiting area is an area where the automobile body waits for coating, and the anode tube voltage of the coating waiting area in the embodiment of the utility model is set to 35V, and the current is set to 5A. The coating area is an area where the automobile body is coated, and the anode tube voltage of the coating area in the embodiment of the utility model is set to 295V, and the current is set to 50A. The coating buffer area is an intermediate area between the coating waiting area and the coating area, and the anode tube voltage and the current of the coating buffer area gradually increase from the coating waiting area to the coating area.

[0039] After the target automobile body enters the electrophoretic tank, the position recognition module 2 sends a radio frequency signal to the tag module 1 on the target automobile body, obtains a response signal of the tag module 1, and obtains the position information of the target automobile body.

[0040] The position recognition module 2 sends the target automobile body position information to the control module 3.

[0041] After obtaining the target automobile body position information, when the tail of the target automobile body enters the coating buffer area from the coating waiting area, the control module 3 controls the anode tube corresponding to the tail of the target automobile body to be powered off. The number of anode tubes is a set value, and in the embodiment of the utility model, three groups of anode tubes are powered off. The utility model adopts the strategy of powering off the anode tube corresponding to the tail of the target automobile body when the tail of the target automobile body enters the coating buffer area from the coating waiting area, thereby reducing the influence of the electric field of the tail of the target automobile body on the front cover of the rear vehicle.

[0042] With the movement of the target automobile body, the control module 3 controls the anode tube group corresponding to the tail of the target automobile body to be powered off in the form of a flowing water lamp. When the front cover of the rear vehicle of the target automobile body reaches the coating buffer area, the control module 3 controls the number of powered-off anode tubes corresponding to the tail of the target automobile body to gradually decrease until it decreases to zero. The utility model eliminates the influence of the electric field of the tail of the target automobile body on the front cover of the rear vehicle by controlling the anode tube corresponding to the tail of the target automobile body, without increasing the distance between the target automobile body and the rear vehicle, thereby increasing the utilization rate of the production line, and the production line can coat more automobile bodies in the same time.

[0043] When the tail of the rear vehicle of the target automobile body enters the coating buffer area from the coating waiting area, the above process is repeated.

[0044] The utility model will be described below in combination with the embodiments in the drawings.

[0045] In the embodiment, the coating waiting area is an area where the vehicle body waits for coating, and the coating waiting area in the embodiment of the utility model comprises 14 groups of anode tubes, the voltage of the anode tubes is set to 35V, and the current is set to 5A. The coating area is an area where the vehicle body is coated, and the voltage of the coating area in the embodiment of the utility model is set to 295V, and the current is set to 50A. The coating buffer area is an intermediate buffer area between the coating waiting area and the coating area, and in the embodiment of the utility model, the coating buffer area comprises 12 groups of anode tubes, the voltage of the 15th group of anode tubes is set to 60V, the current is set to 12A; the voltage of the 16th group of anode tubes is set to 75V, the current is set to 15A; the voltage of the 17th group of anode tubes is set to 90V, the current is set to 18A; the voltage of the 18th group of anode tubes is set to 105V, the current is set to 21A; the voltage of the 19th group of anode tubes is set to 125V, the current is set to 24A; the voltage of the 20th group of anode tubes is set to 145V, the current is set to 28A; the voltage of the 21st group of anode tubes is set to 165V, the current is set to 32A; the voltage of the 22nd group of anode tubes is set to 185V, the current is set to 36A; the voltage of the 23rd group of anode tubes is set to 205V, the current is set to 40A; the voltage of the 24th group of anode tubes is set to 225V, the current is set to 42A; the voltage of the 25th and 26th groups of anode tubes is set to 265V, and the current is set to 46A.

[0046] As shown in Figure 2 , when the tail of the target vehicle body enters the coating buffer area from the coating waiting area, that is, when it enters the 15th group of anode tubes from the 14th group of anode tubes, the control module 3 controls the 14th, 15th and 16th groups of anode tubes to be powered off.

[0047] As the target vehicle body moves, as shown in Figure 3 , the control module 3 controls the 15th, 16th and 17th groups of anode tubes to be powered off.

[0048] As the target vehicle body moves, as shown in Figure 4 , the control module 3 controls the 16th, 17th and 18th groups of anode tubes to be powered off. After the rear vehicle of the target vehicle body enters the coating buffer area, the control module 3 controls the number of powered-off anode tube groups corresponding to the tail of the target vehicle body to gradually decrease, as shown in Figure 5 , the control module 3 controls the 17th and 18th groups of anode tubes to be powered off. As shown in Figure 6 , the control module 3 controls the 18th group of anode tubes to be powered off. Until the number of powered-off anode tube groups corresponding to the tail of the target vehicle body decreases to zero, as shown in Figure 7 , at this time the front cover of the rear vehicle of the target vehicle body has smoothly entered the coating buffer area, and the electric field of the target vehicle body cannot affect the front cover of the rear vehicle.

[0049] As shown in Figure 8 , Figure 9 andFigure 10 As shown, three different length of car model before being improved by the system and method of the utility model, there are stripes on the front cover of the car body, which need a large amount of manual polishing of the electrophoresis paint surface, increasing the cost. After being improved by the system and method of the utility model, the front cover of the car body is free of stripes and anti-rust phenomenon, as shown in Figure 11 .

[0050] The utility model solves the problem of electric field stripes generated during electrophoresis coating of the car body, eliminates the cost of manual polishing, and improves the corrosion resistance and durability of the automobile coating. The utility model solves the problem of flexible production of the electrophoresis production line for different car models, and different car models can be produced on one production line, improving the production capacity.

[0051] The utility model is described above in conjunction with the drawings. Obviously, the specific implementation of the utility model is not limited by the above method. As long as various non-essential improvements are made by using the method concept and technical scheme of the utility model, or the above concept and technical scheme of the utility model are directly applied to other occasions without improvement, they are within the protection scope of the utility model.
