The electrophoretic drainage of the body door sill made of aluminum alloy profiles is considered after the body structure setting is basically completed, and then the expansion glue installation blocks of the body cavity are arranged and designed. After the expansion glue installation blocks are arranged, if the spacing between the slots of the production line is short and the drainage time is insufficient, it will cause the body structure to accumulate excessive liquid and the tank liquid will jump out of the tank, which will seriously affect the stability of the pre-treatment electrophoretic tank liquid parameters. If the residual electrophoretic liquid is retained in the body door sill cavity, after entering the drying furnace, the liquid retention area cannot reach the curing temperature required by the electrophoretic film for a long time, resulting in poor curing of the electrophoretic paint film. Therefore, when designing the electrophoretic drainage plan, how to reasonably optimize the electrophoretic drainage parameters becomes an urgent problem to be solved. Summary of the invention

[0040] References to "one embodiment" or "some embodiments" etc. described in the present specification mean that one or more embodiments of the present invention include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0041] It should be understood that the order of execution of the steps in the following embodiments does not imply a precedence of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0042] See also Figure 1 , is a flow chart of a method for optimizing electrophoretic drainage parameters of a vehicle body sill mounting block provided in Embodiment 1 of the present invention, such as Figure 1 As shown, the electrophoretic drainage parameter optimization method of the vehicle body sill mounting block may include the following steps.

[0043] S101: Obtain the number of electrophoretic drainage boxes of the vehicle body door sill, the drainage gap length and initial gap height at the mounting block in the electrophoretic drainage box, and the liquid surface area representing the liquid to be discharged in the electrophoretic drainage box.

[0044] In step S101, the number of electrophoretic drainage boxes of the vehicle body sill is the number of cavities inside the vehicle body sill, the number of electrophoretic drainage boxes is an integer greater than zero, the length of the drainage gap at the mounting block in the electrophoretic drainage box is the length of the electrophoretic drainage box, the initial gap is a preset height, and the liquid surface area representing the liquid to be discharged in the electrophoretic drainage box is the cross-sectional area of ​​the drainage box.

[0045] In this embodiment, the body door sill is a body door sill made of alloy profile material, the electrophoretic drainage box in the body door sill is honeycomb-shaped, the mounting block in the electrophoretic drainage box is an expansion glue mounting block, and the expansion glue mounting block is installed in the electrophoretic drainage box to prevent the body door sill from being squeezed. When the mounting block is installed in the drainage box, the gap between the drainage box and the mounting block serves as the electrophoretic liquid discharge gap, and the electrophoretic liquid is discharged through the drainage gap.

[0046] It should be noted that when the electrophoretic liquid is discharged through the discharge gap, due to the small discharge gap, if the electrophoretic liquid cannot be completely discharged within the preset process constraint time, the amount of liquid accumulated inside the vehicle body structure will exceed the standard, and the tank liquid will jump out of the tank, which will seriously affect the stability of the pre-treatment electrophoretic tank liquid parameters. The residual electrophoretic liquid will be retained in the door sill cavity of the vehicle body. After entering the drying furnace, the liquid-collecting area cannot reach the curing temperature required for the electrophoretic film for a long time, resulting in poor curing of the electrophoretic paint film.

[0047] Therefore, it is necessary to adjust the spatial size of the drainage gap according to the corresponding preset process constraint time. In this embodiment, the spatial size of the drainage gap is adjusted by adjusting the gap height of the drainage gap. When adjusting the gap height of the drainage gap, first determine whether the overall electrophoresis drainage time of the electrophoresis drainage box is within the preset time range. If not, adjust the gap height of the drainage gap.

[0048] In this embodiment, when calculating the total electrophoretic drainage time of the electrophoretic drainage boxes, firstly, the number of electrophoretic drainage boxes on the vehicle body door sill, the drainage gap length and the initial gap height at the mounting block in the electrophoretic drainage box, and the liquid surface area representing the liquid to be discharged in the electrophoretic drainage box are obtained; based on the number of electrophoretic drainage boxes, the drainage gap length, the initial gap height and the liquid surface area, the total electrophoretic drainage time of all electrophoretic drainage boxes is calculated.

[0049] Among them, the number of electrophoretic drainage boxes of the vehicle body sill, the drainage gap length and initial gap height at the mounting block in the electrophoretic drainage box, and the liquid surface area representing the liquid to be discharged in the electrophoretic drainage box can be obtained by measuring the vehicle body sill structure diagram. During measurement, CATIA (Computer Aided Three-dimensional Interactive Application) measurement tools can be used for measurement.

[0050] It should be noted that when measuring the liquid surface area, the volume of the liquid to be discharged and the boundary height of the electrophoresis drainage box are first measured, and the liquid surface area of ​​the liquid to be discharged is calculated based on the volume of the liquid to be discharged and the boundary height of the electrophoresis drainage box. The calculation formula is as follows:

[0051]

[0052] Wherein, S is the liquid surface area of ​​the liquid to be discharged, V is the volume of the discharged liquid, and H is the boundary height of the electrophoresis drainage box.

[0053] In this embodiment, corresponding known parameters are obtained so that the overall electrophoresis drainage time of all electrophoresis drainage boxes can be calculated based on the known parameters. By directly substituting the parameters, the overall electrophoresis drainage time of all electrophoresis drainage boxes can be quickly obtained, thereby improving calculation efficiency.

[0054] S102: Calculate the total electrophoresis drainage time of all electrophoresis drainage boxes according to the number of electrophoresis drainage boxes, the drainage gap length, the initial gap height and the liquid surface area.

[0055] In step S102, the overall electrophoresis drainage time of the electrophoresis drainage box is the time after the electrophoresis drainage box has drained all the electrophoresis fluid after the mounting block is installed.

[0056] In this embodiment, a first prediction model is obtained, and the number of electrophoresis drainage boxes, the length of the drainage gap, the initial gap height and the liquid surface area are introduced into the first prediction model to calculate the overall electrophoresis drainage time.

[0057] Among them, the first prediction model is a functional relationship model between the overall electrophoresis drainage time and the number of electrophoresis drainage boxes, the drainage gap length, the initial gap height and the liquid surface area.

[0058] See also Figure 2 , is a flow chart of a method for calculating the overall electrophoresis discharge time of all electrophoresis discharge boxes provided in the second embodiment of the present invention, such as Figure 2 As shown, the method for calculating the overall electrophoresis drainage time of all electrophoresis drainage boxes may include the following steps.

[0059] Optionally, the total electrophoresis drainage time of all electrophoresis drainage boxes is calculated according to the number of electrophoresis drainage boxes, the drainage gap length, the initial gap height and the liquid surface area, including:

[0060] S201: Obtaining a first prediction model, the first prediction model including a first functional relationship between the equivalent number of electrophoresis drainage boxes and the number of electrophoresis drainage boxes, a second functional relationship between the drainage volume per unit time of each box and the number of electrophoresis drainage boxes, the drainage gap length, the initial gap height and the liquid surface area, and a third functional relationship between the overall electrophoresis drainage time and the equivalent number and the drainage volume per unit time of each box;

[0061] S202: The number of electrophoresis drainage boxes, the length of the drainage gap, the initial gap height and the liquid surface area are brought into the first prediction model to calculate the overall electrophoresis drainage time of all the electrophoresis drainage boxes.

[0062] In this embodiment, the first prediction model is used to calculate the overall electrophoresis drainage time, wherein the first prediction model includes a first functional relationship between the equivalent number of electrophoresis drainage boxes and the number of electrophoresis drainage boxes, a second functional relationship between the discharge volume per unit time of each box and the number of electrophoresis drainage boxes, the discharge gap length, the initial gap height and the liquid surface area, and a third functional relationship between the overall electrophoresis drainage time and the equivalent number and the discharge volume per unit time of each box.

[0063] Substitute the number of electrophoresis drainage boxes into the first functional relationship to obtain the equivalent number of electrophoresis drainage boxes, where the equivalent number of electrophoresis drainage boxes is the equivalent number of electrophoresis drainage boxes. Substitute the number of electrophoresis drainage boxes, drainage gap length, initial gap height and liquid surface area into the second functional relationship to obtain the drainage volume per unit time of each box, and substitute the equivalent number and the drainage volume per unit time of each box into the third functional relationship to obtain the overall electrophoresis drainage time.

[0064] In this embodiment, the first prediction model is used to calculate the overall electrophoresis drainage time. The first prediction model includes a first functional relationship between the equivalent number and the number of electrophoresis drainage boxes. The equivalent number is calculated, and the equivalent numerical value of the number of electrophoresis drainage boxes is determined, thereby improving the accuracy of the calculation of the number of electrophoresis drainage boxes. The overall electrophoresis drainage time is calculated based on the equivalent number, thereby improving the accuracy of the overall electrophoresis drainage time.

[0065] Optionally, the first functional relationship between the equivalent number of electrophoresis discharge boxes and the number of electrophoresis discharge boxes includes:

[0066]

[0067] m is the equivalent number, n is the number of electrophoresis drainage boxes, p is the drainage empirical coefficient of the electrophoresis drainage box, and a and b are parameters.

[0068] In this embodiment, the first functional relationship also includes the empirical drainage coefficient of the electrophoresis drainage box. a and b are parameters greater than 0. In this embodiment, a can take the value of 3.09, b can take the value of 2.1, and the empirical drainage coefficient p of the electrophoresis drainage box is a number greater than 0 and less than 1.

[0069] Optionally, the second functional relationship between the amount of liquid discharged per unit time of each box and the number of electrophoresis liquid discharge boxes, the liquid discharge gap length, the initial gap height and the liquid surface area includes:

[0070]

[0071] Among them, q t is the displacement per unit time of each box, g is the acceleration due to gravity, h is iis the initial gap height, l is the drainage gap length, S is the liquid surface area, p is the drainage empirical coefficient of the electrophoresis drainage box, n is the number of electrophoresis drainage boxes, u is the calibration parameter value, and the drainage empirical coefficient p of the electrophoresis drainage box is a number greater than 0 and less than 1.

[0072] Optionally, the third functional relationship between the overall electrophoresis discharge time and the equivalent number and the discharge volume per unit time of each box includes:

[0073]

[0074] Among them, V i The volume of liquid discharged from each electrophoresis drainage box can be measured using the CATIA measurement tool, where n is the number of electrophoresis drainage boxes, m is the equivalent number, and q is the volume of liquid discharged from each electrophoresis drainage box. t The amount of liquid discharged per unit time for each box.

[0075] S103: comparing the overall electrophoresis discharge time with the preset discharge constraint time to obtain a comparison result.

[0076] In step S103, the calculated total electrophoresis liquid discharge time is compared with a preset liquid discharge constraint time to determine whether the total electrophoresis liquid discharge time satisfies a condition for completing the discharge of the electrophoresis liquid.

[0077] In this embodiment, the corresponding overall electrophoresis drainage time is compared with the preset drainage constraint time to obtain a comparison result, wherein the comparison result includes that the overall electrophoresis drainage time is less than the preset drainage constraint time, or the overall electrophoresis drainage time is greater than the preset drainage constraint time.

[0078] In another embodiment, a corresponding discharge guarantee coefficient may be set for a preset discharge constraint time, and the overall electrophoresis discharge time may be compared with the preset discharge constraint time taking the discharge guarantee coefficient into consideration to obtain a comparison result.

[0079] In this embodiment, by comparing the overall electrophoresis drainage time with the preset drainage constraint time, the size relationship between the overall electrophoresis drainage time and the preset drainage constraint time is determined, so that the gap height can be adjusted according to the comparison result, which simplifies the process of gap height parameter optimization and improves the efficiency of parameter optimization.

[0080] S104: When the comparison result does not meet the preset condition, the gap height at the mounting block in the electrophoresis drainage box is adjusted to obtain an adjusted gap height.

[0081] In step S104, the preset condition is one of the situations that may occur in the comparison result. The gap height at the mounting block in the electrophoresis drainage box is adjusted according to the comparison result to obtain an adjusted gap height, wherein the adjusted gap height is based on the adjusted gap height to make the overall electrophoresis drainage time closer to the preset drainage constraint time.

[0082] In this embodiment, the calculation formula of the preset condition is as follows:

[0083] t≤λT

[0084] Wherein, t is the overall electrophoresis discharge time, λ is the discharge guarantee coefficient, T is the preset discharge constraint time, and λ is (0.7, 0.8). When the comparison result does not meet the preset conditions, it is considered that the initial gap and initial height meet the conditions, and there is no need to adjust the initial gap height, and the electrophoresis liquid can be discharged using the initial gap height.

[0085] When the comparison result does not meet the preset conditions, the gap height at the mounting block in the electrophoresis drainage box is adjusted to obtain the adjusted gap height. It should be noted that when the gap height is adjusted, the range of each adjustment is uncertain, and multiple adjustments can be made, and the range of the adjusted gap height is (0.003 meters, 0.007 meters).

[0086] When the comparison result meets the preset conditions, the initial gap height is directly used as the final optimized gap height parameter.

[0087] In this embodiment, by comparing the results, it is determined whether to optimize the gap height of the drainage gap. When the comparison result meets the preset conditions, there is no need to optimize the gap height, and the initial gap height is used as the final gap height. When the comparison result does not meet the preset conditions, the gap height at the mounting block in the electrophoresis drainage box is adjusted to achieve the purpose of optimizing the gap height, saving the gap height parameter optimization time and improving the optimization efficiency.

[0088] S105: recalculating the overall electrophoresis drainage time according to the adjusted gap height, and comparing the overall electrophoresis drainage time with the drainage constraint time again until the comparison result meets a preset condition.

[0089] In step S105, the overall electrophoresis discharge time is recalculated according to the adjusted gap height, and the recalculated overall electrophoresis discharge time is re-compared with the discharge constraint time to obtain a re-comparison result, and based on the re-comparison result, it is determined whether the preset conditions are met.

[0090] In this embodiment, the overall electrophoresis drainage time is recalculated based on the adjusted gap height, and the overall electrophoresis drainage time is compared with the drainage constraint time again until the comparison result meets the preset conditions. When recalculating the overall electrophoresis drainage time, the number of electrophoresis drainage boxes, the drainage gap length, the adjusted gap height and the liquid surface area are brought into the first prediction model to calculate the overall electrophoresis drainage time of all electrophoresis drainage boxes.

[0091] In this embodiment, the overall electrophoresis drainage time is recalculated based on the adjusted gap height so that the comparison result between the recalculated overall electrophoresis drainage time and the drainage constraint time meets the preset conditions, so as to achieve the purpose of parameter optimization after the adjusted gap height and prevent the electrophoresis liquid from being discharged completely within the drainage constraint time based on the adjusted gap height.

[0092] See also Figure 3 , is a flow chart of a method for calculating the overall electrophoresis discharge time of an electrophoresis discharge box provided in Embodiment 3 of the present invention, such as Figure 3 As shown, the method for calculating the overall electrophoresis drainage time of the electrophoresis drainage box may include the following steps.

[0093] Optionally, when the number of electrophoretic drainage boxes of the vehicle body door sill is one, calculating the total electrophoretic drainage time of the electrophoretic drainage box includes:

[0094] S301: obtaining liquid surface area representing the liquid to be discharged in the electrophoresis drainage box, the drainage gap length at the mounting block in the electrophoresis drainage box, and the initial gap height;

[0095] S302: The liquid surface area, the drainage gap length and the initial gap height are brought into a second prediction model of the preset overall electrophoresis drainage time to calculate the overall electrophoresis drainage time of the electrophoresis drainage box.

[0096] The second prediction model includes the functional relationship between the electrophoresis drainage time and the liquid surface area, the drainage gap length and the initial gap height.

[0097] In this embodiment, when the number of electrophoretic drainage boxes in the body sill is one, that is, the number of cavities in the body sill is one, the probability that the electrophoretic drainage boxes simultaneously discharge the electrophoretic liquid is 100%. According to the law of conservation of matter, the volume of the liquid to be discharged in the electrophoretic drainage box is equal to the liquid flow rate discharged during the drainage interval discharge time, and the calculation formula is as follows:

[0098]

[0099] Wherein, H is the boundary height of the electrophoresis drainage box, S is the liquid surface area of ​​the liquid to be discharged in the electrophoresis drainage box, h is the variable of the boundary height of the electrophoresis drainage box, and the value range of h is (0, H), t0 is the time for the electrophoresis fluid to be discharged from the drainage gap at the mounting block in the electrophoresis drainage box, v is the flow rate per unit time of the liquid in the drainage gap, and t is the variable of the time for the electrophoresis fluid to be discharged from the drainage gap at the mounting block in the electrophoresis drainage box, and the value range of t is (0, t 0 ). The fluid theory of water can obtain the flow rate of the liquid in the drainage gap per unit time as follows:

[0100]

[0101] According to the formula With the formula The second prediction model is calculated and the calculation formula of the second prediction model is as follows:

[0102]

[0103] Among them, t 0 is the time for discharging the electrophoresis liquid from the drainage gap at the mounting block in the electrophoresis drainage box, S is the liquid surface area of ​​the liquid to be discharged in the electrophoresis drainage box, s is the drainage area of ​​the drainage gap, H is the boundary height of the electrophoresis drainage box, and g is the gravitational acceleration.

[0104] Wherein, s can be obtained by multiplying the drainage gap length at the mounting block in the electrophoresis drainage box by the initial gap height, so the calculation formula of the second prediction model can also be as follows:

[0105]

[0106] Among them, t 0 is the time for the electrophoresis liquid to be discharged from the drainage gap at the mounting block in the electrophoresis drainage box, S is the liquid surface area of ​​the liquid to be discharged in the electrophoresis drainage box, H is the boundary height of the electrophoresis drainage box, g is the gravitational acceleration, and h is the gravitational acceleration. i is the initial gap height, l is the drainage gap length. The liquid surface area, drainage gap length and initial gap height are brought into the second prediction model to calculate the overall electrophoresis drainage time of the electrophoresis drainage box.

[0107] In this embodiment, the number of electrophoretic drainage boxes is single, that is, the electrophoretic drainage box is definitely used during the electrophoretic drainage process, and there is no need to calculate the equivalent number of electrophoretic drainage boxes. According to the law of conservation of matter and energy, the volume of liquid to be discharged is equal to the liquid flow rate flowing out at a certain flow rate within a certain period of time, which reduces the complexity of the calculation, simplifies the calculation process, and thus improves the calculation efficiency.

[0108] See also Figure 4 , is a flow chart of a method for optimizing electrophoretic drainage parameters of a vehicle body sill mounting block provided by a fourth embodiment of the present invention, such as Figure 4As shown, the electrophoretic drainage parameter optimization method of the vehicle body sill mounting block may include the following steps.

[0109] S401: Obtain the number of electrophoretic drainage boxes of the vehicle body door sill, the length of the drainage gap at the mounting block in the electrophoretic drainage box, the liquid surface area representing the liquid to be discharged in the electrophoretic drainage box, and the overall drainage constraint time of all electrophoretic drainage boxes.

[0110] In step S401, the number of electrophoretic drainage boxes of the vehicle body sill is the number of cavities inside the vehicle body sill, the length of the drainage gap at the mounting block in the electrophoretic drainage box is the length of the electrophoretic drainage box, the liquid surface area representing the liquid to be discharged in the electrophoretic drainage box is the cross-sectional area of ​​the drainage box, and the overall drainage constraint time of the electrophoretic drainage box is the completion time of the electrophoretic process.

[0111] In this embodiment, the number of electrophoretic drainage boxes on the vehicle body sill and the length of the drainage gap at the mounting block in the electrophoretic drainage box are obtained, and the liquid surface area of ​​the liquid to be discharged in the electrophoretic drainage box is characterized by measuring the vehicle body sill structure diagram. During the measurement, CATIA (Computer Aided Three-dimensional Interactive Application) measurement tools can be used for measurement.

[0112] It should be noted that when measuring the liquid surface area, the volume of the liquid to be discharged and the boundary height of the electrophoresis drainage box are first measured, and the liquid surface area of ​​the liquid to be discharged is calculated based on the volume of the liquid to be discharged and the boundary height of the electrophoresis drainage box. The calculation formula is as follows:

[0113]

[0114] Wherein, S is the liquid surface area of ​​the liquid to be discharged, V is the volume of the discharged liquid, and H is the boundary height of the electrophoresis drainage box.

[0115] In this embodiment, corresponding known parameters are obtained so that the overall electrophoresis drainage time of all electrophoresis drainage boxes can be calculated based on the known parameters. By directly substituting the parameters, the overall electrophoresis drainage time of all electrophoresis drainage boxes can be quickly obtained, thereby improving calculation efficiency.

[0116] S402: Calculating the ideal height of the drainage gap at the mounting block in the electrophoresis drainage box according to the number of electrophoresis drainage boxes, the length of the drainage gap, the liquid surface area and the overall drainage constraint time;

[0117] In step S402, the ideal height of the drainage gap at the mounting block in the electrophoresis drainage box is the height of the liquid level of the electrophoresis liquid discharged from the electrophoresis drainage box after the mounting block is installed.

[0118] In this embodiment, a prediction model of an ideal height is obtained, and the number of electrophoresis drainage boxes, the length of the drainage gap, the liquid surface area, and the overall drainage constraint time are brought into the prediction model of the ideal height to calculate the ideal height of the drainage gap. The prediction model of the ideal height is a functional relationship model between the number of electrophoresis drainage boxes, the length of the drainage gap, the liquid surface area, and the overall drainage constraint time.

[0119] See also Figure 5 , is a flow chart of a method for calculating an ideal height of a drainage gap at a mounting block in an electrophoresis drainage box provided in a fifth embodiment of the present invention, such as Figure 5 As shown, the method for calculating the ideal height of the drainage gap at the mounting block in the electrophoresis drainage box may include the following steps.

[0120] Optionally, according to the number of electrophoresis drainage boxes, the length of the drainage gap, the liquid surface area and the overall drainage constraint time, the ideal height of the drainage gap at the mounting block in the electrophoresis drainage box is calculated, including:

[0121] S501: Obtaining a prediction model for an ideal height, the prediction model for the ideal height comprising a first functional relationship between an equivalent number and the number of electrophoresis drainage boxes, and a second functional relationship between the ideal height and a liquid surface area, a total drainage constraint time, a drainage gap length, and an equivalent number and the number of electrophoresis drainage boxes;

[0122] S502: The number of electrophoresis drainage boxes, the length of the drainage gap, the liquid surface area and the overall drainage constraint time are brought into the prediction model of the ideal height to obtain the ideal height of the drainage gap at the mounting block in the electrophoresis drainage box.

[0123] In this embodiment, the ideal height of the drainage gap is calculated using a prediction model for the ideal height, wherein the prediction model for the ideal height includes a first functional relationship between the equivalent number of electrophoretic drainage boxes and the number of electrophoretic drainage boxes, and a second functional relationship between the ideal height and the liquid surface area, the overall drainage constraint time, the drainage gap length, and the equivalent number and the number of electrophoretic drainage boxes.

[0124] Substitute the number of electrophoresis drainage boxes into the first functional relationship to obtain the equivalent number of electrophoresis drainage boxes, where the equivalent number of electrophoresis drainage boxes is the equivalent number of electrophoresis drainage boxes. Substitute the liquid surface area, the overall drainage constraint time, the drainage gap length, the equivalent number and the number of electrophoresis drainage boxes into the prediction model of the ideal height to obtain the ideal height of the drainage gap at the mounting block in the electrophoresis drainage box.

[0125] The first functional relationship between the equivalent number of electrophoresis discharge boxes and the number of electrophoresis discharge boxes includes:

[0126]

[0127] m is the equivalent number, n is the number of electrophoresis drainage boxes, p is the drainage empirical coefficient of the electrophoresis drainage box, and a and b are parameters. The first functional relationship also includes the drainage empirical coefficient of the electrophoresis drainage box, a and b are parameters greater than 0. In this embodiment, a can be 3.09, b can be 2.1, and the drainage empirical coefficient p of the electrophoresis drainage box is a number greater than 0 and less than 1.

[0128] The second functional relationship between the ideal height and the liquid surface area, the overall drainage constraint time, the drainage gap length, the equivalent number and the number of electrophoresis drainage boxes includes:

[0129]

[0130] Among them, V i The volume of liquid discharged from each electrophoresis drainage box can be measured using the CATIA measurement tool, where n is the number of electrophoresis drainage boxes, m is the equivalent number, l is the drainage gap length, S is the liquid surface area, t is the overall drainage constraint time, p is the drainage empirical coefficient of the electrophoresis drainage box, and u is the calibration parameter value. The drainage empirical coefficient p of the electrophoresis drainage box is a number greater than 0 and less than 1.

[0131] In this embodiment, a prediction model for ideal height is used to calculate the ideal value of the gap height. The prediction model for ideal height includes a first functional relationship between the equivalent number and the number of electrophoretic drainage boxes. The equivalent number is calculated, and the equivalent numerical value of the number of electrophoretic drainage boxes is determined, thereby improving the accuracy of the calculation of the number of electrophoretic drainage boxes. The ideal height is calculated based on the equivalent number, thereby improving the accuracy of the ideal height.

[0132] S403: Acquire the actual height of the drainage gap at the mounting block in the electrophoresis drainage box, and determine the target height of the drainage gap at the mounting block in the electrophoresis drainage box according to the actual height and the ideal height.

[0133] In step S403, the target height of the drainage gap at the mounting block in the electrophoresis drainage box is determined according to the actual height and the ideal height, wherein the actual height is the preset height of the drainage gap and the target height is one of the actual height and the ideal height.

[0134] In this embodiment, the actual height is compared with the ideal height, and the target height of the drainage gap at the mounting block in the electrophoresis drainage box is determined from the ideal height and the time height.

[0135] It should be noted that if the value range of the target height is limited, it is determined whether the target height meets the value range limit. If it does, the target height is the final target height. If not, the final target height is determined from the value range limited by the target height.

[0136] In this embodiment, the actual height of the drainage gap at the mounting block in the electrophoresis drainage box is obtained, and the target height is selected from the actual height and the ideal height. The target height can be obtained with one selection, avoiding multiple adjustments, simplifying the calculation process, and improving calculation efficiency.

[0137] See also Figure 6 , is a flow chart of a method for determining a target height of a drainage gap at a mounting block in an electrophoresis drainage box provided by a sixth embodiment of the present invention, such as Figure 6 As shown, the method for determining the target height of the drainage gap at the mounting block in the electrophoresis drainage box may include the following steps.

[0138] Optionally, determining a target height of a drainage gap at a mounting block in an electrophoresis drainage box according to an actual height and an ideal height includes:

[0139] S601: If the actual height is less than the ideal height, the ideal height is determined as the target height;

[0140] S602: If the actual height is greater than the ideal height, the actual height is determined as the target height.

[0141] In this embodiment, since the overall discharge constraint time of all electrophoretic discharge boxes is used when calculating the ideal height, the calculated ideal height is the minimum height for discharging the electrophoretic liquid within the overall discharge constraint time. When the actual height is less than the ideal height, the ideal height is determined as the target height. If the actual height is greater than the ideal height, the actual height is determined as the target height, and the discharge gap height is adjusted to the target height.

[0142] It should be noted that if the value range of the target height is limited, for example, the value range of the target height is (a, b), then the value range of the ideal height should also be (a, b). If the actual height is less than the ideal height, the ideal height is determined as the target height. Since the ideal height is the minimum height, when the ideal height is less than a, a is taken as the target height.

[0143] In this embodiment, by comparing the ideal height with the actual height, the target height is determined from the actual height and the ideal height, and there is no need to adjust the gap height multiple times, thereby improving the convenience of determining the target height.

[0144] The number of electrophoretic drainage boxes on the door sill of the vehicle body, the drainage gap length and initial gap height at the mounting block in the electrophoretic drainage box, and the liquid surface area representing the liquid to be discharged in the electrophoretic drainage box are obtained; the overall electrophoretic drainage time of all electrophoretic drainage boxes is calculated according to the number of electrophoretic drainage boxes, the drainage gap length, the initial gap height and the liquid surface area; the overall electrophoretic drainage time is compared with the preset drainage constraint time to obtain a comparison result; when the comparison result does not meet the preset conditions, the gap height at the mounting block in the electrophoretic drainage box is adjusted to obtain the adjusted gap height; the overall electrophoretic drainage time is recalculated according to the adjusted gap height; the overall electrophoretic drainage time is compared with the drainage constraint time again until the comparison result meets the preset conditions. In the present application, during the electrophoretic drainage process, the height of the drainage gap in the drainage box is quantified to calculate the total electrophoretic drainage time of all electrophoretic drainage boxes. The calculated total electrophoretic drainage time is compared with the preset drainage constraint time to adjust the height of the drainage gap according to the comparison result so that the height parameter of the drainage gap can be optimized. Based on the adjusted drainage gap height, the electrophoretic fluid can be completely drained within the preset drainage constraint time to prevent the amount of electrophoretic fluid accumulated inside the vehicle body from exceeding the standard and the occurrence of tank liquid jumping, so as to improve the stability of the electrophoretic tank liquid parameters.
