[0001] The present application relates to the technical field of paint spraying, in particular to a paint spraying control method and device, an electronic device and a storage medium. BACKGROUND

[0002] At present, most paint spraying systems determine the flow required for the spray gun to spray, so as to determine the consumption of paint, by adjusting process parameters. However, the process of adjusting process parameters is relatively complex, which has high technical requirements for the adjuster. In addition, when the spraying flow changes, the staff is not easy to detect, or after detection, it is difficult to make timely adjustment of the spraying flow, thus leading to unstable spraying flow, and the consumption of paint for the same object to be sprayed is greatly different, and thus uneven spraying occurs. SUMMARY

[0003] The purpose of the embodiments of the present application is to provide a paint spraying control method and device, an electronic device and a storage medium, which can keep the spraying flow of the spray gun stable, avoid the consumption of paint for the same object to be sprayed being greatly different, and thus avoid uneven spraying.

[0004] In a first aspect, the embodiments of the present application provide a paint spraying control method applied to a paint spraying system, and the method comprises the following steps.

[0005] Obtaining discharge information when the spray gun sprays;

[0006] According to the discharge information, calculating the consumption of paint when the spray gun sprays;

[0007] According to the consumption of paint and a preset target consumption, adjusting the pressure value of a spraying pump to adjust the spraying flow of the spray gun and the discharge information.

[0008] In the above implementation process, the paint spraying control method of the embodiments of the present application can obtain the discharge information when the spray gun sprays, calculate the consumption of paint when the spray gun sprays, and combine the preset target consumption to adjust the pressure value of the spraying pump, so as to adjust the spraying flow of the spray gun and the discharge information, keep the consumption of paint of the spray gun consistent with the preset target consumption, thereby keeping the spraying flow of the spray gun stable, avoiding the consumption of paint for the same object to be sprayed being greatly different, and thus avoiding uneven spraying, and improving the spraying quality and spraying effect.

[0009] Further, the discharge information is the discharge volume;

[0010] The calculation of the consumption of paint when the spray gun sprays according to the discharge information comprises the following steps.

[0011] The paint consumption of the spray gun is calculated according to the product of the discharge volume and the paint density divided by the predetermined paint coverage area.

[0012] In the above implementation process, the paint consumption of the spray gun can be directly, quickly and accurately calculated according to the product of the discharge volume and the paint density divided by the predetermined paint coverage area, so as to facilitate the adjustment of the pressure value of the spraying pump.

[0013] Further, the adjustment of the pressure value of the spraying pump according to the paint consumption and the preset target consumption includes:

[0014] The pressure value of the spraying pump is adjusted according to the value of the paint consumption minus the preset target consumption, so as to adjust the spraying flow of the spray gun and the discharge information.

[0015] In the above implementation process, the pressure value of the spraying pump can be conveniently and accurately adjusted according to the value of the paint consumption minus the preset target consumption, so as to conveniently and accurately adjust the spraying flow of the spray gun and the discharge information.

[0016] Further, the adjustment of the pressure value of the spraying pump according to the value of the paint consumption minus the preset target consumption, so as to adjust the spraying flow of the spray gun and the discharge information, includes:

[0017] When the value of the paint consumption minus the preset target consumption is within the allowable error range, the pressure value of the spraying pump is maintained, so as to maintain the spraying flow of the spray gun and the discharge information.

[0018] When the value of the paint consumption minus the preset target consumption is less than the lower limit of the allowable error, the pressure value of the spraying pump is increased according to a predetermined pressure increasing mode, so as to increase the spraying flow of the spray gun and the discharge information.

[0019] When the value of the paint consumption minus the preset target consumption is greater than the upper limit of the allowable error, the pressure value of the spraying pump is decreased according to a predetermined pressure decreasing mode, so as to decrease the spraying flow of the spray gun and the discharge information.

[0020] In the above implementation process, the pressure value of the spraying pump is adjusted according to the value of the paint consumption minus the preset target consumption, so as to adjust the spraying flow of the spray gun and the discharge information, which combines the allowable error range, so as to better adjust the pressure value of the spraying pump and avoid increasing the adjustment load of the pressure value of the spraying pump due to slight adjustment.

[0021] Further, the increasing of the pressure value of the spraying pump according to the predetermined pressure increasing mode includes:

[0022] The target pressure value of the spraying pump is calculated according to N*(1+K), and the pressure value of the spraying pump is increased based on the target pressure value;

[0023] The pressure value of the spraying pump is decreased according to a predetermined pressure decreasing mode.

[0024] The target pressure value of the spraying pump is calculated according to N*(1-K), and the pressure value of the spraying pump is decreased based on the target pressure value.

[0025] N is the current pressure value of the spraying pump, and K is the pump pressure adjustment ratio.

[0026] In the above implementation process, when the pressure value of the spraying pump is adjusted, the parameter of the pump pressure adjustment ratio is introduced, so that the adjustment amount can be controlled, and the target value can be adjusted more quickly, accurately and intelligently, and the conditions of excessive adjustment or too small adjustment amount can be avoided.

[0027] Further, the spray gun sprays in a row;

[0028] Before the step of obtaining the discharge information of the spray gun during spraying, the method further comprises:

[0029] The change information of the spraying flow of the spray gun is obtained in units of rows under a predetermined number of rows.

[0030] It is judged whether the change information of the spraying flow is consistent.

[0031] If yes, the step of obtaining the discharge information of the spray gun during spraying is performed.

[0032] In the above implementation process, in actual spraying work, various factors inevitably lead to fluctuations in the spraying flow of each row under the same pump pressure. If the pump pressure is directly adjusted, misadjustment may occur to some extent. Therefore, the method can obtain the discharge information of the spray gun during spraying only when the change information of the spraying flow of multiple rows is consistent, so as to adjust the pressure value of the spraying pump, thereby avoiding misadjustment and improving the practicability and efficiency of the coating spraying control method.

[0033] Further, before the step of obtaining the discharge information of the spray gun during spraying, the method further comprises:

[0034] The current spraying flow of the spray gun during spraying is obtained.

[0035] It is judged whether the current spraying flow is consistent with a preset target spraying flow.

[0036] If no, the step of obtaining the discharge information of the spray gun during spraying is performed.

[0037] In the implementation process, the method can acquire the discharge information when the current spraying flow acquired is inconsistent with the preset target spraying flow, and adjust the pressure value of the spraying pump, so that the practicability and efficiency of the coating spraying control method of the embodiment of the application can be improved.

[0038] In a second aspect, the embodiment of the application provides a coating spraying control device applied to a coating spraying system, and the device comprises:

[0039] an acquisition module configured to acquire discharge information when a spray gun sprays;

[0040] a consumption calculation module configured to calculate coating consumption when the spray gun sprays according to the discharge information;

[0041] a control module configured to adjust a pressure value of a spraying pump according to the coating consumption and a preset target consumption, so as to adjust a spraying flow of the spray gun and the discharge information.

[0042] In the implementation process, the coating spraying control device of the embodiment of the application can calculate the coating consumption when the spray gun sprays according to the acquired discharge information, adjust the pressure value of the spraying pump according to the preset target consumption, adjust the spraying flow of the spray gun and the discharge information, so that the coating consumption of the spray gun is consistent with the preset target consumption, the spraying flow of the spray gun is kept stable, the spraying consumption difference of the same object to be sprayed is avoided, and the problem of uneven spraying is avoided, so that the spraying quality and effect are improved.

Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing description, and cannot be understood as indicating or implying relative importance.

[0052] At present, most of the paint spraying systems are to determine the flow required by the spray gun spraying by adjusting the process parameters, so as to determine the consumption of paint; but actually, the process of adjusting the process parameters is relatively complex, which has high technical requirements for the adjuster, and when the spraying flow changes, the staff is not easy to detect, or after detection, it is difficult to make timely adjustment of the spraying flow, thus it is easy to cause the instability of the spraying flow, and it is easy to cause the large difference of the spraying consumption of the same sprayed object, and thus the problem of uneven spraying occurs.

[0053] In view of the problems in the prior art, the present application provides a paint spraying control method, device, electronic equipment and storage medium, which can keep the spraying flow of the spray gun stable, avoid the large difference of the spraying consumption of the same sprayed object, and thus avoid the problem of uneven spraying.

[0054] Embodiment One

[0055] Referring to Figure 1 , Figure 1 A first flowchart of the paint spraying control method provided for the embodiments of the present application. The paint spraying control method described in the embodiments of the present application can be applied to the controller of the paint spraying system.

[0056] Exemplarily, the paint spraying system described above can be a paint spraying system of an external wall spraying robot.

[0057] The paint spraying control method of the embodiments of the present application is applied to the paint spraying system, and includes the following steps:

[0058] Step S130, obtaining the discharging information when the spray gun sprays.

[0059] It can be understood that the paint spraying system comprises a controller, a spray gun and a spraying pump.

[0060] In the embodiment, the discharging information when the spray gun sprays can be the discharging volume or the discharging flow (i.e. the spraying flow) when the spray gun sprays, and the paint spraying control method of the embodiment is explained by taking the discharging volume when the spray gun sprays as an example.

[0061] Optionally, the discharging volume when the spray gun sprays can be obtained by a flow meter.

[0062] In the embodiment, the paint spraying control method of the embodiment is explained by taking the working mode of spraying by rows by the spray gun.

[0063] It can be understood that the discharging volume is the paint volume consumed when the spray gun sprays one row.

[0064] Step S140, calculating the paint consumption when the spray gun sprays according to the discharging information.

[0065] In the embodiment, the paint consumption when the spray gun sprays can be calculated by the discharging volume.

[0066] It can be understood that the paint consumption is the weight of the paint needed for spraying per unit area.

[0067] Step S150, adjusting the pressure value of the spraying pump according to the paint consumption and the preset target consumption, so as to adjust the spraying flow of the spray gun and the discharging information.

[0068] In the embodiment, the preset target consumption is a preset value, which is the target value of the paint consumption after the pressure value of the spraying pump is adjusted, and can be regarded as a reference value for adjusting the pressure value of the spraying pump.

[0069] It can be understood that when the pressure value of the spraying pump is adjusted, the spraying flow of the spray gun is adjusted, and the discharging volume is also adjusted; the spraying flow is the amount of fluid passing through the cross section of the pipeline per unit time.

[0070] For the paint spraying control in the paint spraying control method of the embodiment, please refer to Figure 2 , wherein the pump is the spraying pump, the actual consumption Y is the paint consumption, and the target consumption Y1 is the preset target consumption.

[0071] The paint spraying control method of the embodiment of the application can, when the spray gun is spraying, calculate the paint consumption of the spray gun by the obtained discharge information, adjust the pressure value of the spraying pump in combination with the preset target consumption, adjust the spraying flow of the spray gun and the discharge information, and keep the paint consumption of the spray gun consistent with the preset target consumption, so that the spraying flow of the spray gun can be kept stable, the spraying consumption difference of the same sprayed object can be avoided, and the problem of uneven spraying can be avoided, thereby improving the spraying quality and spraying effect.

[0072] In some embodiments of the application, the step S140 of calculating the paint consumption of the spray gun according to the discharge information can include:

[0073] The paint consumption of the spray gun is calculated according to the product of the discharge volume and the paint density divided by the predetermined paint coverage area.

[0074] Specifically, the paint consumption of the spray gun is calculated by Y = p * V / S, wherein Y is the paint consumption, p is the paint density, V is the discharge volume, and S is the predetermined paint coverage area.

[0075] The predetermined paint coverage area can be calculated according to the predetermined spraying length and width when working by row.

[0076] In the above process, the paint consumption of the spray gun can be directly, quickly and accurately calculated by the product of the discharge volume and the paint density divided by the predetermined paint coverage area, thereby facilitating the adjustment of the pressure value of the spraying pump.

[0077] In some embodiments of the application, the step S150 of adjusting the pressure value of the spraying pump according to the paint consumption and the preset target consumption to adjust the spraying flow of the spray gun and the discharge information can include:

[0078] The pressure value of the spraying pump is adjusted according to the value of the paint consumption minus the preset target consumption to adjust the spraying flow of the spray gun and the discharge information.

[0079] In the above process, the pressure value of the spraying pump can be adjusted conveniently and accurately by the value of the paint consumption minus the preset target consumption, thereby the spraying flow of the spray gun and the discharge information can be adjusted conveniently and accurately.

[0080] Optionally, the pressure value of the spraying pump is adjusted according to the value of the paint consumption minus the preset target consumption to adjust the spraying flow of the spray gun and the discharge information can include:

[0081] When the value of the paint consumption minus the preset target consumption is within the allowable error range, the pressure value of the spraying pump is maintained to maintain the spraying flow of the spray gun and the discharge information.

[0082] When the paint consumption minus the preset target consumption value is less than the lower limit of the allowable error, the pressure value of the spraying pump is increased in a predetermined pressure increasing mode to increase the spraying flow of the spray gun and the discharging information.

[0083] When the paint consumption minus the preset target consumption value is greater than the upper limit of the allowable error, the pressure value of the spraying pump is decreased in a predetermined pressure decreasing mode to decrease the spraying flow of the spray gun and the discharging information.

[0084] It can be understood that when the paint consumption minus the preset target consumption value is within the allowable error range, the pressure value of the spraying pump is maintained, which is also regarded as the adjustment of the pressure value of the spraying pump.

[0085] In the above process, the method adjusts the pressure value of the spraying pump by the paint consumption minus the preset target consumption value, and combines the allowable error range to adjust the spraying flow of the spray gun and the discharging information, so that the pressure value of the spraying pump can be better adjusted, and the adjustment load of the pressure value of the spraying pump can be reduced due to slight adjustment.

[0086] Further, the pressure value of the spraying pump is increased in the predetermined pressure increasing mode, including:

[0087] The target pressure increasing value of the spraying pump is calculated according to N*(1+K), and the pressure value of the spraying pump is increased based on the target pressure increasing value;

[0088] The pressure value of the spraying pump is decreased in the predetermined pressure decreasing mode, including:

[0089] The target pressure decreasing value of the spraying pump is calculated according to N*(1-K), and the pressure value of the spraying pump is decreased based on the target pressure decreasing value;

[0090] Wherein, N is the current pressure value of the spraying pump, and K is the pump pressure adjustment ratio.

[0091] Specifically, the pressure value of the spraying pump is increased based on the target pressure increasing value, that is, the pressure value of the spraying pump is increased to the target pressure increasing value; and the pressure value of the spraying pump is decreased based on the target pressure decreasing value, that is, the pressure value of the spraying pump is decreased to the target pressure decreasing value.

[0092] In the above process, the method introduces the parameter of the pump pressure adjustment ratio when adjusting the pressure value of the spraying pump, so that the adjustment amount can be controlled, and the target value can be adjusted more quickly, accurately and intelligently, and the conditions of excessive adjustment or too small adjustment amount can be avoided.

[0093] Referring to Figure 3 , Figure 3 The second flowchart of the paint spraying control method provided by the embodiment is shown.

[0094] In some embodiments of the present application, the paint spraying control method of the present application can further comprise the following steps before the step S130 of obtaining the discharge information of the spray gun during spraying:

[0095] The step S110 comprises: obtaining the change information of the spraying flow of the spray gun in units of rows under a predetermined number of rows.

[0096] The step S120 comprises: judging whether the change information of the spraying flow of the plurality of rows is consistent.

[0097] Specifically, if the change information of the spraying flow of the plurality of rows is consistent, the steps S130 to S150 are executed; if the change information of the spraying flow of the plurality of rows is not consistent, the present process is ended.

[0098] The change information of the spraying flow of the plurality of rows can be understood as the change information of the spraying flow of the plurality of rows.

[0099] Optionally, the change information of the spraying flow can be the change trend of the spraying flow or the change curve of the spraying flow.

[0100] In the above process, in actual spraying work, various factors inevitably cause the spraying flow of each row to fluctuate under the same pump pressure. If the pump pressure is directly adjusted, the adjustment may be inaccurate to some extent. Therefore, the method can obtain the discharge information of the spray gun during spraying only when the change information of the spraying flow of the plurality of rows is consistent, so as to adjust the pressure value of the spraying pump, thereby avoiding inaccurate adjustment and improving the practicability and efficiency of the paint spraying control method of the present application.

[0101] In some embodiments of the present application, the paint spraying control method of the present application can further comprise the following steps before the step S130 of obtaining the discharge information of the spray gun during spraying:

[0102] The step S130 comprises: obtaining the current spraying flow of the spray gun during spraying.

[0103] The step S140 comprises: judging whether the current spraying flow is consistent with the preset target spraying flow.

[0104] Specifically, if the current spraying flow is not consistent with the preset target spraying flow, the steps S130 to S150 are executed; if the current spraying flow is consistent with the preset target spraying flow, the present process is ended.

[0105] In the above process, the method can obtain the discharge information of the spray gun during spraying only when the current spraying flow obtained is not consistent with the preset target spraying flow, and adjust the pressure value of the spraying pump, thereby improving the practicability and efficiency of the paint spraying control method of the present application.
