Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are only used to illustrate the present invention, but are not used to limit the protection scope of the present invention. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

In the description of the present invention, it should be understood that the numbers themselves, such as "first", "second", etc., are only used to distinguish the described objects, have no sequence or technical meaning, and cannot be construed as regulations Or imply the importance of the object being described.

It should be noted that, in the prior art, the vehicle is automatically painted by a painting robot. Therefore, the input of the vehicle body type and painting color is very critical. However, the current spraying robot compares the vehicle model, color and derivation (with or without a sunroof) by manual input and PMS comparison. When the comparison data is consistent, the data in the PMS is used as the spraying data. When the PMS fails, the comparison process is lost, and the spraying data is directly obtained by manual input. If the wrong model is entered manually, it will lead to the risk of collision between the robot and the model. There is no risk of color or excessive spraying. If the wrong color is entered manually, it will lead to the risk of wrong color of the car body, and there will also be the risk of scrapping. In view of this, in the process of vehicle color spraying, the present invention adds a model detection device to obtain the model of the vehicle, and adds a comparison step between the model and the manually input model, so as to add an insurance line of defense for the error prevention of vehicle spraying. , thereby reducing the probability of errors.

FIG. 1 is a schematic structural diagram of a preferred embodiment of a vehicle color spray detection system provided by the present invention.

As shown in Figure 1, the detection system for vehicle color spraying includes:

The engineering production management system 11 is used to obtain the first model data and the first spray color data of the vehicle;

a vehicle type detection device 12, used for acquiring the second vehicle type data of the vehicle;

The data acquisition module 13 is used to acquire the manually inputted third model data and the second spray color data;

The model comparison module 14 is configured to compare the first model data with the third model data to obtain a first comparison result, and compare the second model data with the third model data to obtain a first comparison result. Two comparison results and comparing the first spray color data with the second spray color data to obtain a third comparison result;

The color spraying device 15 is configured to, when the first comparison result, the second comparison result and the third comparison result are all consistent with the comparison data, use the second spraying color data to paint the vehicle on the vehicle. Color spray.

Specifically, the engineering production management system (ie PMS) reads the chip data of the vehicle through the chip reading head, and then determines the first model data and the first spraying data of the vehicle, or determines the first model data of the vehicle, First derived data and first spray data.

The vehicle type detection device identifies the vehicle type through the photocells arranged on both sides of the vehicle traveling, and then determines the second vehicle type data of the vehicle. Wherein, the specific detection principle of the vehicle type detection device is as follows: multiple groups of photocells are arranged on both sides of the vehicle, and each group of photocells detects the light. The amount of light through the windows or doors of the vehicle can be used to set and identify the model.

It should be noted that in the present invention, the first model data and the first spraying data of the vehicle can be obtained through the engineering production management system, and then the second model data of the vehicle can be obtained through the model detection device; The vehicle type detection device acquires the second type data of the vehicle, and then acquires the first type data and the first spraying data of the vehicle through the engineering production management system. Both implementations are within the protection scope of the present invention.

The data is compared, and when the data is correct, the control manipulator takes the manually input spray color data as the criterion, and selects different colors of paint to spray the vehicle.

It can be understood that when the data to be compared also includes derived data, that is, the data obtained by the engineering production management system also includes the first derived data, and the data obtained by the data acquisition module also includes the manually input second derived data. When all the comparison results are consistent with the comparison data, the manually input spraying color data shall prevail, and paints of different colors are selected to spray the vehicle.

The present invention provides a detection system for vehicle color spraying. In the process of vehicle color spraying, a vehicle type detection device is added to obtain the vehicle type data, and the vehicle type data obtained by the vehicle type detection device is compared with the manually input vehicle type data.

Then, the alarm module 16 is also used for:

When the fourth comparison result is that the comparison data is inconsistent, an alarm is issued.

It should be noted that, in the prior art, after the vehicle has completed the color spraying, it is only through manual visual inspection to confirm whether there is a wrong color spraying, but usually the operator will also have other work contents, and they are not specially responsible for the inspection. Because of the low accuracy of visual inspection, when the wrong color is similar to the correct color, it is difficult to be found manually, which will lead to scrapped vehicles or high rework costs. In view of this, the present invention also adds a color detection device to obtain the vehicle body color data after the vehicle completes color spraying, and adds a comparison step between the vehicle body color data and the manually input spray color data. , adds another insurance line of defense for the error-proofing of vehicle spraying, further reducing the probability of errors.
