To improve the efficiency and quality of circuit board production, conformal adhesive coating is usually performed using automated equipment (adhesive spraying machines). The use of adhesive spraying machines improves the efficiency of conformal adhesive spraying to a certain extent and also reduces the harm of conformal adhesive to the human body.

[0003] Currently, in the application of glue spraying machines, users need to set the control parameters of the glue spraying machine according to their own glue spraying quality requirements; according to the set control parameters, the glue spraying machine executes the glue spraying command to carry out the glue spraying operation; after the glue spraying operation is completed, users need to visually observe and judge the glue spraying quality; if the glue spraying quality is judged to be unsatisfactory, the control parameters of the glue spraying machine are then corrected based on personal experience.

The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0075] Those skilled in the art will understand that Figure 1 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0076] like Figure 1 As shown, the memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a glue spraying control program.

[0077] The operating system is a program that manages and controls the glue spraying machine and software resources, and supports the operation of the network communication module, user interface module, glue spraying control program and other programs or software; the network communication module is used to manage and control the network interface 1002; the user interface module is used to manage and control the user interface 1003.

[0078] exist Figure 1 In the glue spraying machine shown, the glue spraying machine calls the glue spraying control program stored in the memory 1005 through the processor 1001 and executes the operations in the various embodiments of the glue spraying control method described below.

[0079] Based on the above hardware structure, an embodiment of the adhesive spraying control method of the present invention is proposed.

[0080] Reference Figure 2 , Figure 2 This is a schematic flowchart of the first embodiment of the glue spraying control method of the present invention. The glue spraying control method includes:

[0081] Step S10: Obtain the glue spraying quality target, which is used to characterize the desired glue spraying effect.

[0082] Step S20: Determine the control parameters of the glue spraying machine according to the glue spraying quality target;

[0083] Step S30: Based on the control parameters, control the glue spraying machine to perform glue spraying test according to the preset test trajectory to obtain the glue spraying test quality;

[0084] Step S40: If the glue spraying test quality meets the glue spraying quality target, the glue spraying machine is controlled to perform glue spraying operation using the control parameters.

[0085] This embodiment obtains a glue spraying quality target, which characterizes the desired glue spraying effect; determines the control parameters of the glue spraying machine based on the glue spraying quality target; adjusts the glue spraying machine according to the control parameters, and controls the adjusted glue spraying machine to perform glue spraying tests according to a preset test trajectory to obtain the glue spraying test quality; if the glue spraying test quality meets the glue spraying quality target, the glue spraying machine is controlled to perform glue spraying operations according to the control parameters; by collecting the glue spraying operation results, the relationship model is continuously changed, improving the relationship model's prediction accuracy of glue spraying quality; thereby improving glue spraying efficiency and glue spraying quality stability, and saving labor costs.

[0086] The following will provide a detailed explanation of each step:

[0087] Step S10: Obtain the adhesive spraying quality target, which is used to characterize the desired adhesive spraying effect.

[0088] In this embodiment, the glue spraying control method of the present invention is applied to a glue spraying machine. This method automatically sets and adjusts the control parameters of the glue spraying machine according to the glue spraying quality target, and automatically monitors the glue spraying quality; thus, a closed-loop control is formed between the control parameters and the glue spraying quality during the glue spraying operation. The application of the glue spraying method of the present invention not only saves labor costs but also ensures high-quality glue spraying production. (Refer to...) Figure 3 , Figure 3 This is a diagram of the overall architecture of the glue spraying machine;

[0089] Reference Figure 4 , Figure 4 This is a schematic diagram of the glue spraying machine in operation. The glue spraying quality target of the glue spraying machine is set in advance. The glue spraying quality target is used to characterize the desired glue spraying effect, and the glue spraying quality target includes, but is not limited to, glue splatter distance, target glue thickness value, etc.; for example, no glue splatter during the glue spraying process.

[0090] Step S20: Determine the control parameters of the glue spraying machine according to the glue spraying quality target.

[0091] In this embodiment, the control parameters of the glue spraying machine are determined according to the above-mentioned glue spraying quality target, so that the glue spraying machine after adjusting the control parameters can achieve the glue spraying quality target.

[0092] The control parameters of the glue spraying machine can be divided into two categories: glue spraying process parameters and mechanism motion parameters. Glue spraying process parameters may include parameters such as glue flow rate and atomization pressure; mechanism motion parameters may include parameters such as spraying height, moving speed, and acceleration / deceleration. It is understood that in some embodiments, the above control parameters may also include other parameters, such as glue spraying duration, etc. The specific settings can be made according to actual conditions, and this specification does not limit this aspect in the embodiments.

[0093] Furthermore, in one embodiment, reference is made to... Figure 5 Step S20 includes:

[0094] Step S21: Obtain the target relationship model, which is used to characterize the correlation between the quality of the spray adhesive and the control parameters;

[0095] Step S22: Determine the control parameters of the glue spraying machine based on the glue spraying quality target and the target relationship model.

[0096] In this embodiment, based on the above-mentioned glue spraying quality target and the obtained target relationship model, the control parameters of the corresponding glue spraying machine are set and adjusted so that the glue spraying machine after adjusting the control parameters achieves the glue spraying quality target; wherein, the target relationship model is a pre-constructed mathematical expression between the glue spraying quality target and the control parameters, and the target relationship model is used to characterize the correlation between glue spraying quality and control parameters.

[0097] By determining the corresponding control parameters of the glue spraying machine through the glue spraying quality target and target relationship model, and automatically monitoring the glue spraying quality of the glue spraying machine, the control parameters and glue spraying quality target control form a closed loop, thereby realizing automatic control of glue spraying quality, improving the stability of glue spraying quality, and saving labor costs.

[0098] Step S30: Based on the control parameters, control the glue spraying machine to perform glue spraying test according to the preset test trajectory to obtain the glue spraying test quality.

[0099] In this embodiment, refer to Figure 4 , Figure 4 The diagram illustrates the operation of the glue spraying machine. Based on the control parameters set above, the glue spraying machine is adjusted, and the glue spraying machine after adjusting the control parameters is controlled to perform glue spraying tests according to the preset test trajectory to obtain the glue spraying test quality. The preset test trajectory is the motion trajectory of the glue spraying test that is pre-set in the glue spraying machine.

[0100] Among them, the quality of glue spraying test refers to the glue spraying effect achieved after the glue spraying machine performs the glue spraying test.

[0101] After conducting the adhesive spraying test, the quality of the adhesive spraying test is detected by visual inspection to determine whether the quality of the adhesive spraying test meets the user's set adhesive spraying quality target.

[0102] If the quality of the adhesive spraying test meets the adhesive spraying quality target, the above-mentioned control parameters are used to control the adhesive spraying machine to perform large-scale adhesive spraying operations.

[0103] If the quality of the adhesive spraying test does not meet the adhesive spraying quality target, the above control parameters need to be adjusted until the adhesive spraying test quality can meet the adhesive spraying quality target.

[0104] Furthermore, in one embodiment, reference is made to... Figure 6 After step S30, the adhesive spraying control method also includes:

[0105] Step Z10: If the glue spraying test quality does not meet the glue spraying quality target, update the target relationship model based on the error between the glue spraying test quality and the glue spraying quality target.

[0106] Step Z20: Based on the updated target relationship model and the glue spraying quality target, determine the control parameters of the glue spraying machine until the glue spraying test quality meets the glue spraying quality target.

[0107] In this embodiment, if the glue spraying test quality does not meet the glue spraying quality target, for example, if the glue splatter distance and / or glue thickness do not meet the above-mentioned glue spraying quality target.

[0108] The quality of the adhesive spraying test is compared with the adhesive spraying quality target to obtain the error between the two. The target relationship model is then updated to obtain the updated target relationship model. Specifically, the update process involves correcting the adhesive spraying process parameters and mechanism motion parameters in the target relationship model so that the corrected target relationship model can achieve the adhesive spraying quality target.

[0109] Then, based on the updated target relationship model and glue spraying quality target, the control parameters in the glue spraying machine are redefined until the glue spraying test quality of the glue spraying machine meets the glue spraying quality target. By evaluating the glue spraying quality of the glue spraying machine according to the quantifiable standard evaluation criteria of the glue spraying quality target, the control parameters of the glue spraying machine are automatically set and adjusted to achieve closed-loop control between the control parameters and the glue spraying quality. This enables the evaluation of the glue spraying quality of the glue spraying machine using quantifiable standard evaluation criteria, and also saves labor costs and improves the stability of glue spraying quality.

[0110] In addition, it can monitor the glue spraying quality and glue flow rate when the glue spraying machine performs glue spraying operations, and determine whether to correct the control parameters of the glue spraying machine or remind the glue spraying valve of the glue spraying machine to clean and maintain it.

[0111] Step S40: If the glue spraying test quality meets the glue spraying quality target, the glue spraying machine is controlled to perform glue spraying operation using the control parameters.

[0112] In one embodiment, reference is made to Figure 4 , Figure 4 This is a schematic diagram of the glue spraying machine's operation. When the glue spraying test quality meets the glue spraying quality target, the glue spraying machine is controlled under these parameters to perform large-scale glue spraying operations. A closed-loop control is formed through the control parameters and glue spraying quality target control, thereby achieving automatic control of glue spraying quality, improving the stability of glue spraying quality, and saving labor costs.

[0113] This embodiment obtains a glue spraying quality target, which characterizes the desired glue spraying effect; determines the control parameters of the glue spraying machine based on the glue spraying quality target; adjusts the glue spraying machine according to the control parameters, and controls the adjusted glue spraying machine to perform glue spraying tests according to a preset test trajectory to obtain the glue spraying test quality; if the glue spraying test quality meets the glue spraying quality target, the glue spraying machine is controlled to perform glue spraying operations according to the control parameters; by collecting the glue spraying operation results, the relationship model is continuously changed, improving the relationship model's prediction accuracy of glue spraying quality; thereby improving glue spraying efficiency and glue spraying quality stability, and saving labor costs.

[0114] Furthermore, based on the first embodiment of the adhesive spraying control method of the present invention, a second embodiment of the adhesive spraying control method of the present invention is proposed.

[0115] The second embodiment of the glue spraying control method differs from the first embodiment in that, in this embodiment, before step S20, which involves determining the control parameters of the glue spraying machine based on the glue spraying quality target, references... Figure 7 The glue spraying control method further includes:

[0116] Step A10: Set multiple different sets of sample control parameters;

[0117] Step A20: Control the glue spraying machine to perform glue spraying operation using each of the sample control parameters to obtain the corresponding glue spraying quality sample set;

[0118] Step A30: Perform data fitting on the plurality of sample control parameter sets and the corresponding adhesive quality sample sets to obtain the target relationship model.

[0119] In this embodiment, multiple different sample control parameter sets can be set, and each sample control parameter can be used to control the glue spraying machine to perform glue spraying operations, thereby obtaining a corresponding glue spraying quality sample set. Data fitting is performed on multiple sample control parameter sets and the corresponding glue spraying quality sample sets to obtain a target relationship model corresponding to the sample control parameter sets and the glue spraying quality sample sets. As glue spraying production proceeds, the target relationship model will be continuously corrected and improved, thereby improving the accuracy of the target relationship model in predicting glue spraying quality indicators.

[0120] In this embodiment, the above-mentioned sample control parameter set may include a set of control parameter samples. Each set of control parameter samples may include: glue spraying process parameters, mechanism motion parameters, etc., wherein the glue spraying process parameters may include parameters such as glue flow rate and atomization pressure, and the mechanism motion parameters may include parameters such as glue spraying height, moving speed, and acceleration and deceleration.

[0121] The following will provide a detailed explanation of each step:

[0122] Step A10: Set multiple sets of sample control parameters;

[0123] Step A20: Control the glue spraying machine to perform glue spraying operation using each of the sample control parameters to obtain the corresponding glue spraying quality sample set.

[0124] In this embodiment, the user sets multiple different sets of sample control parameters on the glue spraying machine. These control parameters include glue spraying process parameters and mechanism motion parameters. The glue spraying process parameters include glue flow rate and atomization pressure, while the mechanism motion parameters include glue spraying height, moving speed, and acceleration / deceleration. After setting multiple sets of sample control parameters with different combinations, the glue spraying machine can be controlled to perform glue spraying operations using each set of parameters, obtaining a glue spraying quality sample set corresponding to each combination. This sample set of glue spraying quality parameters may include glue splatter distance, glue thickness, and other glue spraying quality parameters corresponding to a single set of control parameters.

[0125] It should be noted that, in order to ensure the accuracy of the target relationship model, the sample control parameter set should be large enough. The embodiments in this specification do not limit the number of sample control parameter sets, which can be determined according to actual needs. In practical applications, the more sample control parameter sets there are, the more accurate the relationship between the glue spraying quality target and the control parameters in the target relationship model will be.

[0126] Step A30: Perform data fitting on the plurality of sample control parameter sets and the corresponding adhesive quality sample sets to obtain the target relationship model.

[0127] In this embodiment, after obtaining the glue quality sample set corresponding to each sample control parameter, data fitting can be performed on each sample control parameter set and each glue quality sample set; wherein, the fitting method includes, but is not limited to: linear fitting, nonlinear fitting, neural network calculation fitting, etc.

[0128] After data fitting, a mathematical relationship can be obtained between the glue quality sample set and the sample control parameter set. This relationship can characterize the target relationship model between glue quality and control parameters. Based on the input glue quality target, the corresponding control parameters can be determined using the target relationship model.

[0129] As the amount of data obtained, including the sample control parameter set and the corresponding glue quality sample set, increases, the mathematical relationship between the glue quality sample set and the sample control parameter set will be refitted, thereby automatically generating a new target relationship model.

[0130] This target relationship model is a mathematical expression between the glue spraying quality target and the control parameters of the glue spraying machine; based on the glue spraying quality target, the control parameters of the glue spraying machine can be set and adjusted so that the glue spraying machine achieves the glue spraying quality target after the control parameters are adjusted.

[0131] In this embodiment, multiple different sample control parameter sets are set, and each sample control parameter is used to control the glue spraying machine to perform glue spraying operations, thereby obtaining a corresponding glue spraying quality sample set. Data fitting is performed on multiple sample control parameter sets and corresponding glue spraying quality sample sets to obtain a target relationship model corresponding to the sample control parameter sets and glue spraying quality sample sets. As glue spraying production proceeds, the target relationship model will be continuously corrected and improved, thereby improving the accuracy of the target relationship model in predicting glue spraying quality indicators.

[0132] Furthermore, based on the first and second embodiments of the adhesive spraying control method of the present invention, a third embodiment of the adhesive spraying control method of the present invention is proposed.

[0133] The third embodiment of the glue spraying control method differs from the first and second embodiments in that it refines step S40, which involves using the control parameters to control the glue spraying machine to perform the glue spraying operation. (Refer to...) Figure 8 This step specifically includes:

[0134] Step D10: Based on the target air pressure value, control the first rotary motor to rotate forward or reverse the pressure regulating knob of the pressure regulating valve to adjust the air pressure in the pressure regulating valve.

[0135] Step D20: Read the current air pressure value in the pressure regulating valve;

[0136] Step D30: Compare the current air pressure value with the target air pressure value;

[0137] Step D40: If the current air pressure value is inconsistent with the target air pressure value, the first rotary motor is controlled to adjust the pressure regulating knob according to the error between the current air pressure value and the target air pressure value until the air pressure value in the pressure regulating valve is consistent with the target air pressure value.

[0138] In this embodiment, the pressure regulating knob of the first rotary motor is controlled to rotate forward or backward according to the target air pressure value to adjust the air pressure in the pressure regulating valve; the current air pressure value in the pressure regulating valve is read and compared with the target air pressure value; if the current air pressure value is inconsistent with the target air pressure value, the first rotary motor is controlled to adjust the pressure regulating knob according to the error between the current air pressure value and the target air pressure value until the air pressure value in the pressure regulating valve is consistent with the target air pressure value; thereby realizing the automatic adjustment of the input pressure of the pressure regulating valve, and thus ensuring high-quality glue spraying production.

[0139] The following will provide a detailed explanation of each step:

[0140] Step D10: Based on the target air pressure value, control the first rotary motor to rotate forward or reverse the pressure regulating knob of the pressure regulating valve to adjust the air pressure in the pressure regulating valve.

[0141] In this embodiment, refer to Figure 9 , Figure 9 This is a schematic diagram illustrating the automatic adjustment of the input pressure of a pressure regulating valve. The glue spraying machine is connected to a pressure regulating valve, and the valve's adjusting knob is connected to a first rotary motor. The control parameters include a target air pressure value, which characterizes the air pressure at which the glue spraying quality meets the target quality during glue spraying operations. In this invention, the first rotary motor replaces a human operator in adjusting the pressure regulating valve, and the current air pressure value is acquired by a sensor built into the valve. After acquiring the current air pressure value, it is compared with the target air pressure value, and an output signal controls the first rotary motor to rotate forward or backward, thereby increasing or decreasing the input air pressure of the pressure regulating valve.

[0142] When the control parameter is the target air pressure value, the pressure regulating knob of the first rotating motor can be controlled to rotate forward or backward according to the target air pressure value, so that the air pressure in the pressure regulating valve can be increased or decreased, and the air pressure in the pressure regulating valve can gradually approach the target air pressure value.

[0143] Step D20: Read the current air pressure value in the pressure regulating valve.

[0144] In this embodiment, refer to Figure 9 , Figure 9 This diagram illustrates the automatic adjustment of input pressure to the pressure regulating valve; it reads the current air pressure value from the pressure regulating valve and compares it with the target air pressure value to check whether the current air pressure value and the target air pressure value are consistent.

[0145] Step D30: Compare the current air pressure value with the target air pressure value.

[0146] In this embodiment, refer to Figure 9 , Figure 9 The diagram illustrates the automatic adjustment of the input pressure of the pressure regulating valve. The current air pressure value is compared with the target air pressure value. If the current air pressure value is inconsistent with the target air pressure value, it means that the air pressure adjustment of the glue sprayer has not been completed. Therefore, it is necessary to control the first rotary motor to adjust the air pressure in the pressure regulating valve according to the difference between the current air pressure value and the target air pressure value until the air pressure value in the pressure regulating valve is consistent with the target air pressure value.

[0147] When the current air pressure value matches the target air pressure value, it means that the air pressure regulation of the glue spraying machine has been completed, and the current air pressure value in the pressure regulating valve is the target air pressure value. The current air pressure value is then used to control the glue spraying machine to perform large-volume glue spraying operations.

[0148] Step D40: If the current air pressure value is inconsistent with the target air pressure value, the first rotary motor is controlled to adjust the pressure regulating knob according to the error between the current air pressure value and the target air pressure value until the air pressure value in the pressure regulating valve is consistent with the target air pressure value.

[0149] In this embodiment, refer to Figure 9 , Figure 9 This diagram illustrates the automatic adjustment of the input pressure to the pressure regulating valve. When the current air pressure value matches the target air pressure value, it indicates that the air pressure adjustment of the glue spraying machine has not yet been completed. Therefore, it is necessary to control the first rotary motor to adjust the pressure regulating knob according to the difference between the current air pressure value and the target air pressure value until the air pressure value in the pressure regulating valve matches the target air pressure value. This achieves automatic adjustment of the input pressure in the pressure regulating valve, thereby ensuring high-quality glue spraying production.

[0150] In this embodiment, the pressure regulating knob of the first rotary motor is controlled to rotate forward or backward according to the target air pressure value to adjust the air pressure in the pressure regulating valve; the current air pressure value in the pressure regulating valve is read and compared with the target air pressure value; if the current air pressure value is inconsistent with the target air pressure value, the first rotary motor is controlled to adjust the pressure regulating knob according to the error between the current air pressure value and the target air pressure value until the air pressure value in the pressure regulating valve is consistent with the target air pressure value; thereby realizing the automatic adjustment of the input pressure of the pressure regulating valve, and thus ensuring high-quality glue spraying production.

[0151] Furthermore, based on the first, second, and third embodiments of the adhesive spraying control method of the present invention, a fourth embodiment of the adhesive spraying control method is proposed.

[0152] The fourth embodiment of the glue spraying control method differs from the first, second, and third embodiments in that this embodiment refines step S40, which involves using the control parameters to control the glue spraying machine to perform the glue spraying operation. (Refer to...) Figure 10 This step specifically includes:

[0153] Step E10: Based on the target glue flow rate, control the second rotary motor to rotate the scale of the glue spray valve to adjust the outlet glue flow rate of the glue spray valve;

[0154] Step E20: Measure the mass of adhesive dispensed from the adhesive spray valve using the weighing balance;

[0155] Step E30: Determine the current glue flow rate based on the current outlet glue quality;

[0156] Step E40: Compare the current adhesive flow rate with the target adhesive flow rate;

[0157] Step E50: If the current glue flow rate is inconsistent with the target glue flow rate, the rotary motor is controlled to rotate the scale of the glue spray valve according to the error between the current glue flow rate and the target glue flow rate until the current glue flow rate of the glue spray valve is consistent with the target glue flow rate.

[0158] In this embodiment, the glue flow rate at the outlet of the glue spraying valve is adjusted by controlling the scale of the second rotary motor to rotate according to the target glue flow rate; the current glue mass at the outlet of the glue spraying valve is measured by a weighing balance; the current glue flow rate is compared with the target glue flow rate; if the current glue flow rate and the target glue flow rate are inconsistent, the scale of the rotary motor to rotate the glue spraying valve is adjusted according to the error between the current glue flow rate and the target glue flow rate until the current glue flow rate of the glue spraying valve is consistent with the target glue flow rate; thereby realizing automatic control of the glue flow rate of the glue spraying valve, and thus ensuring high-quality glue spraying production.

[0159] The following will provide a detailed explanation of each step:

[0160] Step E10: Based on the target glue flow rate, control the second rotary motor to rotate the scale of the glue spray valve to adjust the outlet glue flow rate of the glue spray valve.

[0161] In this embodiment, refer to Figure 11 , Figure 11This is a schematic diagram of automatic control of glue flow rate for a glue spraying valve. The glue spraying machine includes a second rotary motor, a glue spraying valve, and a weighing balance. Control parameters include a target glue flow rate, which characterizes the glue flow rate at which the glue spraying quality meets the target quality during glue spraying operations. In this invention, the second rotary motor replaces a human operator in controlling the scale at the top of the glue spraying valve. Furthermore, this invention proposes using a weighing balance to measure the glue mass at the outlet of the glue spraying valve. The glue flow rate is obtained by dividing the outlet glue mass by the corresponding time consumed.

[0162] The glue flow rate is obtained by measuring the signal from the weighing balance, and the output signal controls the second rotary motor, which in turn controls the scale of the glue spraying valve to adjust the glue flow rate, thus achieving closed-loop automatic control of the glue flow rate. The weighing balance is installed inside the glue spraying machine and can be accessed at any time during glue spraying operations. The glue flow rate is also used to determine and adjust the working status of the glue spraying machine.

[0163] Based on the target air pressure value, the scale of the spray valve is controlled to rotate forward or backward according to the second rotary motor, so as to increase or decrease the outlet glue flow rate in the spray valve, so that the outlet glue flow rate of the spray valve gradually approaches the target glue flow rate.

[0164] Step E20: Measure the current outlet adhesive mass of the adhesive spray valve using the weighing balance.

[0165] In this embodiment, refer to Figure 11 , Figure 11 This is a schematic diagram of the automatic control of glue flow rate in the glue spraying valve; the current glue mass at the outlet of the glue spraying valve is measured using a weighing balance.

[0166] Step E30: Determine the current glue flow rate based on the current export glue quality.

[0167] In this embodiment, refer to Figure 11 , Figure 11 This is a schematic diagram of the automatic control of glue flow rate for the glue spray valve; the current glue flow rate is calculated by dividing the current outlet glue quality by the corresponding time.

[0168] Step E40: Compare the current adhesive flow rate with the target adhesive flow rate.

[0169] In this embodiment, the current glue flow rate is compared with the target glue flow rate to detect whether they are consistent. When the glue flow rate matches the target flow rate, it indicates that the glue flow control of the spray valve has been completed, and the current glue flow rate in the spray valve is controlled to the target air pressure value. When the glue flow rate does not match the target flow rate, it indicates that the glue flow control of the spray valve has not yet been completed, and it is necessary to control the second rotary motor to rotate the scale of the spray valve based on the difference between the current and target glue flow rates to adjust the outlet glue flow rate of the spray valve to reach the target glue flow rate.

[0170] Step E50: If the current glue flow rate is inconsistent with the target glue flow rate, the rotary motor is controlled to rotate the scale of the glue spray valve according to the error between the current glue flow rate and the target glue flow rate until the current glue flow rate of the glue spray valve is consistent with the target glue flow rate.

[0171] In this embodiment, refer to Figure 11 , Figure 11 This diagram illustrates the automatic control of glue flow rate in a glue spray valve. When the current glue flow rate differs from the target flow rate, the rotary motor is controlled to rotate the scale of the glue spray valve based on the error between the current and target flow rates. This adjusts the outlet glue flow rate until the current flow rate matches the target flow rate. This achieves automatic control of the glue flow rate in the glue spray valve, thereby ensuring high-quality glue spraying production.

[0172] In this embodiment, the glue flow rate at the outlet of the glue spraying valve is adjusted by controlling the scale of the second rotary motor to rotate according to the target glue flow rate; the current glue mass at the outlet of the glue spraying valve is measured by a weighing balance; the current glue flow rate is compared with the target glue flow rate; if the current glue flow rate and the target glue flow rate are inconsistent, the scale of the rotary motor to rotate the glue spraying valve is adjusted according to the error between the current glue flow rate and the target glue flow rate until the current glue flow rate of the glue spraying valve is consistent with the target glue flow rate; thereby realizing automatic control of the glue flow rate of the glue spraying valve, and thus ensuring high-quality glue spraying production.

[0173] Furthermore, based on the first, second, third, and fourth embodiments of the adhesive spraying control method of the present invention, a fifth embodiment of the adhesive spraying control method of the present invention is proposed.

[0174] The fifth embodiment of the glue spraying control method differs from the first, second, third, and fourth embodiments in that this embodiment focuses on step S30, where, based on the control parameters, the glue spraying machine is controlled to perform a glue spraying test according to a preset test trajectory, resulting in a refined quality assessment of the glue spraying test. (Refer to...) Figure 12 This step specifically includes:

[0175] Step S31: Based on the control parameters, control the glue spraying machine to perform glue spraying test according to the preset test trajectory to obtain the glued sample;

[0176] Step S32: Take a picture of the sample using the vision device to obtain a spray adhesive test image;

[0177] Step S33: Process the adhesive spraying test image using a preset image algorithm to obtain the adhesive spraying test quality corresponding to the sample.

[0178] This embodiment adjusts the glue spraying machine according to control parameters and controls the machine to perform glue spraying tests according to a preset test trajectory to obtain a glue-sprayed sample. A vision device is used to capture the sample, obtaining a corresponding glue spraying test image. A preset image algorithm is used to process the glue spraying test image to obtain the glue spraying test quality of the sample. Thus, by using a vision device to evaluate the glue spraying quality, the efficiency and stability of the glue spraying operation are improved, and labor costs are saved.

[0179] The following will provide a detailed explanation of each step:

[0180] Step S31: Based on the control parameters, control the glue spraying machine to perform glue spraying test according to the preset test trajectory to obtain the glued sample.

[0181] In this embodiment, the glue spraying machine also includes a motion mechanism and a vision device; the vision device is used to detect the glue spraying quality after the glue spraying machine has finished operating; wherein, the vision device can be a camera, which is installed on the motion mechanism together with the glue spraying valve and can move as the glue spraying position changes.

[0182] Based on the above control parameters, the glue spraying machine is adjusted, and the glue spraying machine after the adjustment parameters is controlled to perform glue spraying test according to the preset test trajectory to obtain the corresponding glued sample; wherein, the preset test trajectory is the motion trajectory of glue spraying test pre-set in the glue spraying machine.

[0183] Step S32: Take a picture of the sample using the vision device to obtain a spray adhesive test image.

[0184] In this embodiment, after the glue spraying test, the glue spraying quality is detected by visual inspection using a camera; specifically, the glue-sprayed sample is photographed by the camera (UV light can be used for supplemental lighting during the photographing process) to obtain the corresponding glue spraying test image; then the glue spraying test image can be further inspected according to a preset image algorithm.

[0185] Step S33: Process the adhesive spraying test image using a preset image algorithm to obtain the adhesive spraying test quality corresponding to the sample.

[0186] In this embodiment, the obtained glue spraying test images are processed by a preset image algorithm to obtain the corresponding glue spraying test quality.

[0187] The preset image algorithms include, but are not limited to, original image extraction, grayscale processing, filtering / edge detection / segmentation, feature extraction and calculation, etc.

[0188] The quality of the adhesive spraying test includes, but is not limited to, adhesive splatter distance, adhesive edge condition, and adhesive coverage area; furthermore, adhesive thickness can be calculated from the adhesive coverage area.

[0189] The test verifies whether the quality of the adhesive spraying meets the user-defined adhesive spraying quality targets.

[0190] If the glue spraying test quality meets the glue spraying quality target, then control the glue spraying machine to perform large-scale glue spraying operations according to the current control parameters.

[0191] If the adhesive spraying test quality does not meet the adhesive spraying quality target, the control parameters need to be adjusted so that the adjusted control parameters can achieve the adhesive spraying quality target. Specifically, if there is a deviation between the test quality index and the adhesive spraying quality target, the adhesive spraying process parameters and mechanism motion parameters of the adhesive spraying machine can be automatically corrected according to the adhesive spraying quality target and the above-mentioned target relationship model, thereby achieving the requirements of the adhesive spraying quality target. After correcting the adhesive spraying process parameters and mechanism motion parameters, the relationship model between the adhesive spraying quality target and the adhesive spraying process parameters and mechanism motion parameters is also corrected.

[0192] In this embodiment, the glue spraying machine is adjusted according to control parameters, and the adjusted glue spraying machine is controlled to perform glue spraying tests according to a preset test trajectory to obtain a glue-sprayed sample; the sample is photographed by a vision device to obtain a corresponding glue spraying test image; the glue spraying test image is processed by a preset image algorithm to obtain the glue spraying test quality corresponding to the sample; thus, the glue spraying quality is evaluated by using a vision device, thereby improving the work efficiency and stability of glue spraying operations, and saving labor costs.

[0193] Furthermore, based on the first, second, third, fourth, and fifth embodiments of the adhesive spraying control method of the present invention, a sixth embodiment of the adhesive spraying control method of the present invention is proposed.

[0194] The sixth embodiment of the glue spraying control method differs from the first, second, third, fourth, and fifth embodiments in that this embodiment, after step S40, where the glue spraying test quality meets the glue spraying quality target, uses the control parameters to control the glue spraying machine to perform the glue spraying operation, refers to... Figure 13 The glue spraying control method further includes:

[0195] Step J10: Obtain the operating parameters of the glue spraying machine when performing glue spraying operations within the target time period;

[0196] Step J20: If the operating parameters meet the preset conditions, generate a prompt message; wherein the preset conditions are used to determine the operating status of the glue spraying machine, and the prompt message is used to indicate that the glue spraying machine needs cleaning and maintenance.

[0197] In this example, by acquiring the operating parameters of the glue spraying machine during the glue spraying operation within the target time period, and generating a prompt message when the operating parameters meet preset conditions, the operating status of the glue spraying machine during the glue spraying operation can be monitored, thereby improving the stability of the glue spraying quality.

[0198] The following will provide a detailed explanation of each step:

[0199] Step J10: Obtain the operating parameters of the glue spraying machine when performing glue spraying operations within the target time period.

[0200] In this example, by obtaining the operating parameters of the glue spraying machine when performing glue spraying operations within the target time period, it is possible to determine whether the control parameters of the glue spraying machine need to be adjusted or to remind the glue spraying valve of the glue spraying machine to be cleaned and maintained.

[0201] The target time period is the pre-set time period during which the glue spraying machine will perform glue spraying operations. Specifically, it can be set to one week, one month, or one quarter. The target time period is set according to the actual situation.

[0202] Furthermore, in one embodiment, reference is made to... Figure 14 After step J10, the following steps are also included:

[0203] Step J30: If the running parameters meet the preset conditions, update the target relationship model using the running parameters;

[0204] Step J40: Based on the updated target relationship model and the glue spraying quality target, update the control parameters of the glue spraying machine.

[0205] In this example, when the operating parameters of the glue spraying machine meet preset conditions, the target relationship model is updated based on these operating parameters to obtain an updated target relationship model. Then, based on the updated target relationship model and the aforementioned glue spraying quality target, the control parameters of the glue spraying machine are updated. The preset conditions are used to determine the operating status of the glue spraying machine.

[0206] By monitoring the glue spraying quality, the control parameters of the glue spraying machine can be adjusted, thereby achieving high-quality glue spraying production.

[0207] Furthermore, in one embodiment, reference is made to... Figure 15 After step J10, the following steps are also included:

[0208] Step J50: Obtain a preset glue flow rate threshold, wherein the preset glue flow rate threshold is a pre-set index used to characterize the glue spraying state when the glue spraying machine performs glue spraying operation;

[0209] Step J60: If the decrease in glue flow rate is greater than the preset glue flow rate threshold, a prompt message is generated; wherein, the prompt message is used to remind the glue spraying machine to be cleaned and maintained;

[0210] Step J70: If the decrease in glue flow rate is not greater than the preset glue flow rate threshold, the control parameters of the glue spraying machine are corrected.

[0211] In this embodiment, the operating parameters may further include the glue flow rate decrease, which characterizes the glue flow rate of the glue spraying machine during glue spraying operations. Under the same control parameters, as the duration of the glue spraying operation increases, the glue spraying valve may become clogged, leading to a decrease in the glue flow rate during the glue spraying process. The user can set a preset glue flow rate threshold, which can be a pre-set indicator used to characterize the glue spraying status of the glue spraying machine during glue spraying operations. When the decrease in the current glue spraying volume compared to the initial value is greater than the preset glue flow rate threshold, it indicates that the glue spraying machine has experienced a malfunction such as clogging and requires cleaning and maintenance.

[0212] If the decrease in glue flow rate exceeds the preset glue flow rate threshold, the user should be reminded to clean and maintain the glue spraying valve of the glue spraying machine.

[0213] If the decrease in glue flow rate is not greater than the preset glue flow rate threshold, the control parameters of the glue spraying machine can be automatically corrected. For example, if the decrease in glue flow rate is less than the preset glue flow rate threshold, it means that the current glue spraying quality of the glue spraying machine does not meet the glue spraying quality target. By comparing the current glue spraying quality with the glue spraying quality target, the error between the current glue spraying quality and the glue spraying quality target is obtained, and the decrease in glue flow rate is corrected according to the error, so that the corrected glue flow rate decrease reaches the preset glue flow rate threshold, and the glue spraying machine with corrected parameters can achieve the glue spraying quality target.

[0214] By utilizing historical monitoring results of glue flow rate reduction and glue spraying quality, it can determine whether to automatically adjust the control parameters of the glue spraying machine or remind the glue spraying machine to perform cleaning and maintenance reminders; thereby improving the automatic control of glue spraying quality.

[0215] Step J20: If the operating parameters meet the preset conditions, generate a prompt message; wherein the preset conditions are used to determine the operating status of the glue spraying machine, and the prompt message is used to indicate that the glue spraying machine needs cleaning and maintenance.

[0216] In this example, a prompt message is generated when the operating parameters of the glue spraying machine meet the preset conditions; the preset conditions are used to determine the operating status of the glue spraying machine, and the prompt message indicates that the glue spraying machine needs to be cleaned and maintained.

[0217] In this embodiment, by acquiring the operating parameters of the glue spraying machine during the glue spraying operation within the target time period, and generating a prompt message when the operating parameters meet preset conditions, the operating status of the glue spraying machine during the glue spraying operation can be monitored, thereby improving the stability of the glue spraying quality.

[0218] The present invention also provides a glue spraying control device. (See reference...) Figure 16 The adhesive spraying control device of the present invention includes:
