[0045] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0046] As Figure 3 shown, this is a flowchart of the working process of a method for abnormal warning of a glue application system according to an embodiment of the present invention, including:

[0047] Step S301, in response to a spraying operation, monitor the spraying glue hose of the glue application system that performs the spraying operation, and obtain monitoring data;

[0048] Step S302, detect the monitoring data, and perform an alarm operation when the monitoring data is abnormal.

[0049] Specifically, the present invention can be applied to an electronic device with processing capabilities, such as a controller.

[0050] Specifically, a detection device is installed on the spraying glue hose. When performing a spraying operation, step S301 is executed. In response to the spraying operation, monitor the spraying glue hose of the glue application system that performs the spraying operation, and obtain monitoring data.

[0051] Among them, the glue application system is preferably a robot glue application system. The spraying operation is to spray the glue material from the spraying glue hose connected to the spray gun to the spraying area. For example, the spraying glue hose sprays the glue material to the vehicle chassis through the spray gun.

[0052] The monitoring data includes but is not limited to: the flow rate of the glue material.

[0053] Then step S302 is executed to detect the monitoring data, and an alarm operation is performed when the monitoring data is abnormal.

[0054] Specifically, the alarm operation includes, but is not limited to, audible and visual alarms, screen output of alarm information, etc.

[0055] In the present invention, by monitoring the spraying hose that performs the spraying operation on the gluing system, when the monitored data is abnormal, an alarm operation is performed, thereby monitoring the spraying state in real time, reducing the phenomenon of missed spraying, avoiding the outflow of batch defects, improving product quality, and meeting the requirements of high-precision spraying processes.

[0056] As Figure 4 shown is a flowchart of the working process of a method for early warning of abnormalities in a gluing system according to another embodiment of the present invention, including:

[0057] Step S401, in response to the spraying operation, monitor the spraying hose that performs the spraying operation on the gluing system, and obtain the flow rate of the glue material in the spraying hose as the monitored data.

[0058] Step S402, detect the monitored data, and when the flow rate is greater than the maximum flow rate threshold or when the flow rate is less than the minimum flow rate threshold, determine that the monitored data is abnormal and perform an alarm operation.

[0059] Step S403, when the monitored data is abnormal, output the position information of the spraying performed by the spraying operation.

[0060] Specifically, when performing the spraying operation, step S401 is triggered. In response to the spraying operation, the spraying hose that performs the spraying operation on the gluing system is monitored, and the flow rate of the glue material in the spraying hose is obtained as the monitored data.

[0061] Specifically, as Figure 5 shown, in the gluing system, the glue material is sprayed through the spraying hose. Therefore, by using the original layout structure of the robot 2 and the metering machine device 3 in the gluing system, a spraying hose 1 capable of installing an ultrasonic pulse sensor is set, and the ultrasonic pulse sensor is used to detect the change in the flow of the glue amount inside the spraying hose 1. Among them, the spraying hose 1 is preferably a high-pressure pipe.

[0062] The monitored value in this embodiment is the flow rate of the glue material. The fluctuation of the glue amount in the robot spraying hose will cause pressure abnormality or viscosity abnormality in the spraying hose. Therefore, by monitoring the change in the flow rate in real time, the discharge amount state of the spraying system is judged, and the problem of missed spraying caused by the fluctuation of the glue amount is avoided.

[0063] In one of the embodiments, the obtaining the flow rate of the glue material in the spraying hose as the monitored data includes:

[0064] Obtain the ultrasonic information of the ultrasonic sensor clamped outside the spraying hose that performs the spraying operation, and calculate the flow rate of the glue material in the spraying hose according to the ultrasonic information as the monitored data.

[0065] Specifically, an ultrasonic sensor is clamped outside the spraying hose.

[0066] As Figure 6 shown, in an embodiment of the present invention, an ultrasonic sensor 11 includes an upper clamping portion 111, a lower clamping portion 112, a first ultrasonic transceiver device 113 and a second ultrasonic transceiver device 114. Among them, the upper ends of the first ultrasonic transceiver device 113 and the second ultrasonic transceiver device 114 are connected to the upper clamping portion 111, and the lower ends of the first ultrasonic transceiver device 113 and the second ultrasonic transceiver device 114 are connected to the lower clamping portion 112. The upper clamping portion 111 is sleeved on the upper end of the spraying hose 1, and the lower clamping portion 112 is sleeved on the lower end of the spraying hose 1. The first ultrasonic transceiver device 113 and the second ultrasonic transceiver device 114 clamp the spraying hose 1, and the ultrasonic waves transmitted and received by the first ultrasonic transceiver device 113 and the second ultrasonic transceiver device 114 pass through the spraying hose 1.

[0067] Specifically, Figures 6 to 9 shown, the upper clamping portion 111 refers to the connection joint component of the metering machine equipment. The upper clamping portion 111 is sleeved on the upper end of the spraying hose 1, and the lower clamping portion 112 refers to the connection joint component of the lower connecting hose. The lower clamping portion 112 is sleeved on the lower end of the spraying hose 1. Tighten the upper clamping portion 111 and the lower clamping portion 112, and then the first ultrasonic transceiver device 113 sends ultrasonic waves (downward ultrasonic waves) towards the second ultrasonic transceiver device 114, and the second ultrasonic transceiver device 114 sends ultrasonic waves (upward ultrasonic waves) towards the first ultrasonic transceiver device 113. The first ultrasonic transceiver device 113 and the second ultrasonic transceiver device 114 can receive ultrasonic waves simultaneously. The ultrasonic waves will pass through the spraying hose 1 clamped by the first ultrasonic transceiver device 113 and the second ultrasonic transceiver device 114, and the propagation time or speed will be changed by the glue material in the spraying hose 1. Therefore, by actually receiving the ultrasonic pulse signals emitted by the first ultrasonic transceiver device 113 and the second ultrasonic transceiver device 114, recording the propagation time difference, and then calculating the corresponding glue material flow rate according to the propagation time difference.

[0068] In some embodiments, calculating the flow rate of the glue material in the spraying hose according to the ultrasonic information includes:

[0069] Obtaining the first propagation time of the first ultrasonic pulse emitted by the first ultrasonic transceiver device 113 towards the second ultrasonic transceiver device 114;

[0070] Obtaining the second propagation time of the second ultrasonic pulse emitted by the second ultrasonic transceiver device 114 towards the first ultrasonic transceiver device 113;

[0071] Calculate the propagation time difference between the first propagation time and the second propagation time;

[0072] Calculate the flow velocity of the rubber compound as v = L / (2cosθ) * [Δt / (t1 * t2)], where v is the flow velocity of the rubber compound, L is the ultrasonic emission path length, Δt is the propagation time difference, t1 is the first propagation time, t2 is the second propagation time, and θ is the angle between the ultrasonic wave and the flow direction of the rubber compound fluid.

[0073] Specifically:

[0074] The first ultrasonic transceiver 113 emits an ultrasonic pulse (in the downstream direction) to the second ultrasonic transceiver 114, and records the first propagation time as t1;

[0075] The second ultrasonic transceiver 114 emits an ultrasonic pulse (in the upstream direction) to the first ultrasonic transceiver 113, and records the second propagation time as t2;

[0076] Calculate the propagation time difference Δt = t2 - t1;

[0077] The ultrasonic emission path length is measured as L;

[0078] The angle between the ultrasonic wave and the flow direction of the rubber compound fluid is measured as θ;

[0079] The flow velocity of the rubber compound is calculated as v = L / (2cosθ) * [Δt / (t1 * t2)];

[0080] Calculate the average value of multiple measurements to reduce random errors.

[0081] The ultrasonic sensor in this embodiment adopts a clamp-type detection device, which avoids inserting the sensor into the internal part of the mechanical component or contacting the rubber compound. The ultrasonic sensor in this embodiment has no pressure loss, no blockage, and requires no maintenance, and will not affect the normal operation of the flow velocity of the rubber hose.

[0082] In one of the embodiments, obtaining the ultrasonic information of the ultrasonic sensor clamped outside the spraying rubber hose performing the spraying operation, and calculating the flow velocity of the rubber compound in the spraying rubber hose as monitoring data according to the ultrasonic information, includes:

[0083] Obtain the ultrasonic information of the ultrasonic sensor clamped outside the spraying rubber hose performing the spraying operation;

[0084] Filter the ultrasonic information, and calculate the flow velocity of the rubber compound in the spraying rubber hose as monitoring data according to the filtered ultrasonic information.

[0085] Specifically, use a digital filtering algorithm to exclude the noise interference of the impact data fluctuation during the spraying process, and accurately reflect the flow velocity corresponding to the abnormal pressure or abnormal viscosity.

[0086] Through a high-speed arithmetic processing method, interference components randomly mixed in can be eliminated, and only correct signal components can be extracted. It can filter and remove 50Hz / 60Hz power frequency interference in a specific frequency or narrow band range in the signal.

[0087] Among them, the sources of equipment interference include:

[0088] Electromagnetic radiation generated by the power system (such as power lines, robot control cabinets, AC equipment of metering machines);

[0089] Fixed interference at a specific frequency in the communication system or environment (such as radio interference);

[0090] Harmonic interference (high-frequency harmonics in the output signal of frequency converters or inverters).

[0091] Then, step S402 is executed to detect the monitoring data. When the flow rate is greater than the maximum flow rate threshold or the flow rate is less than the minimum flow rate threshold, it is determined that the monitoring data is abnormal, and an alarm operation is executed.

[0092] Specifically, the judgment condition is: if the flow rate detected by the rubber hose exceeds the upper and lower thresholds, it is determined that there is a leakage spray, and an alarm operation is executed.

[0093] The spraying operation can be in an instantaneous mode. The robot controls the spraying rubber hose to continuously spray at different positions, and each monitoring data is detected. At the same time, each spraying operation at each moment has the position information at that moment. The position information is recorded as the position information of the spraying object.

[0094] Another spraying operation is the area mode. The robot controls the spraying rubber hose to spray a certain area of the spraying object, and then stops spraying and transfers to another area to spray again. Therefore, the position information of the entire area can be recorded.

[0095] In one embodiment, the detection of the monitoring data includes:

[0096] In response to the spraying start command signal, it is marked as the window start time;

[0097] In response to the spraying end command signal, it is marked as the window end time;

[0098] The monitoring data between the window start time and the window end time is detected.

[0099] Specifically, when the robot controls the spraying rubber hose to spray a certain area of the spraying object, a spraying start command signal will be generated, and this time is marked as the window start time. When the spraying of this area ends, a spraying end command signal will be generated, and this time is marked as the window end time. Select the monitoring data, such as the flow rate, between the window start time and the window end time for detection

[0100] At the same time, take the entire involved area as a whole and record the position information of the area. And detect the monitoring data. If an abnormality is judged, an early warning operation is executed.

[0101] Finally, execute step S403. When the monitoring data is abnormal, output the position information sprayed by the spraying operation.

[0102] In this embodiment, by online detecting the flow rate, using the digital filtering method and regional digital acquisition processing and analysis, the accurate spraying position is judged. It plays a role in preventing the occurrence of quality problems caused by unstable spraying flow rate. By real-time monitoring the spraying flow rate fluctuation, when an abnormality is found, a pre-alarm is triggered. At the same time, it can quickly locate the missed spraying position, provide suggestions on the inspection order of the spraying position points, and display the degree of missed spraying with a quantitative index (such as percentage). This embodiment realizes automated management, the system real-time monitors the spraying state, replaces manual regular spot checks, and improves management efficiency.

[0103] This embodiment improves the spraying quality. By real-time monitoring the spraying state, it reduces the phenomenon of missed spraying, avoids the outflow of batch defects, and improves the product quality. At the same time, this embodiment can improve the maintenance efficiency. By quickly locating the fault point, providing maintenance suggestions, shortening the fault troubleshooting time, and improving the equipment maintenance efficiency. In addition, this embodiment can reduce the labor cost. By replacing manual visual inspection, reducing manual intervention, and reducing the management cost. Finally, this embodiment can enhance the system reliability. By combining the non-invasive detection device and the digital filtering algorithm, it ensures the accuracy of the monitoring data and the stability of the system.

[0104] As Figure 10 shown in the working flowchart of an abnormal early warning method for a glue coating system according to the best embodiment of the present invention, including:

[0105] Step S1001, start system detection;

[0106] Step S1002, measure the flow rate, convert the analog quantity into a digital quantity and transfer it to the register in the programmable controller (collect continuously)

[0107] Step S1003, collect the spraying start command signal and mark it as the window start time;

[0108] Step S1004, collect the spraying end command signal and mark it as the window end time;

[0109] Step S1005, execute the digital filtering algorithm and detect the execution of the pattern;

[0110] Step S1006, if the flow rate is within the upper and lower threshold ranges, the operation is normal, execute the next action, otherwise execute Step S1007;

[0111] Step S1007, obtain the robot position point information and extract the area value;

[0112] Step S1008, determine the risk of spray flow rate fluctuation;

[0113] Step S1009, send out the position information of the corresponding missed spray area;

[0114] Step S1010, stop the equipment and perform manual inspection;

[0115] Step S1011, if the spraying state is restored, the operation is normal, execute the next action.

[0116] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

[0117] Specifically, according to the running trajectory of the robot teaching, collect and record the number and sequence data of gun switching in different areas for each vehicle model, count the sequence and total number of the robot gun switching and gluing signals, accumulate and count multiple gun sprayings of the robot as one area, assign an area value for identifying the area to each area, and record the position range included in each area. When performing the spraying work on the vehicle, for each area, send out a spraying start instruction signal at the start of the area, and send out a spraying end instruction signal at the end of the area, calculate the sum of the actual rubber material flow rates between the spraying start instruction signal and the spraying end instruction signal, and compare it with the set threshold of the area. If the deviation exceeds the setting, it is determined as abnormal. At the same time, according to the robot position point information, find the area value of the area whose position range covers the robot position point. Determine the risk of spray flow rate fluctuation, regard this area as the missed spray area, and send out the position information of the corresponding missed spray area to remind manual inspection.
