Description

Technical Field

[0001] This specification relates to the field of non-standard automation, and in particular to an auxiliary material stripping device and a control system. Background Art

[0002] When preparing electronic products, it involves the peeling and adsorption of die-cut products. This process usually requires the auxiliary materials to be peeled off from the release paper and adsorbed.

[0003] When proofing auxiliary materials, more and more manufacturers use laser cutting to make auxiliary material rolls. Laser cutting is a semi-cutting process, that is, it only cuts off a layer of auxiliary materials without cutting the release paper. After cutting, the waste part and the useful auxiliary material part will stick to the release paper together. Therefore, it is difficult to accurately peel off the auxiliary material part of the required part and separate the waste part. At the same time, in the process of peeling auxiliary materials, the incorrect posture of the auxiliary materials and the overheated environment temperature will affect the peeling efficiency of the auxiliary materials.

[0004] In view of this, it is desired to provide an auxiliary material stripping device and a control system that can monitor the auxiliary material stripping process and make appropriate adjustments to achieve more efficient and accurate auxiliary material stripping. Summary of the invention

[0015] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of this specification.

[0019] When stripping auxiliary materials, it is necessary to accurately strip the cut auxiliary materials to avoid the waste materials in the middle of the auxiliary materials being adsorbed. During the stripping process, factors such as inaccurate auxiliary material posture and excessively high ambient temperature may affect the efficiency of the device operation, increase the risk of damaging the auxiliary materials, and increase the residue of waste materials on the auxiliary materials. In view of this, it is hoped to provide an auxiliary material stripping device and control system that can monitor the auxiliary material stripping quality so as to make timely adjustments and achieve more efficient and intelligent auxiliary material stripping.

[0020] Figure 1 It is a schematic diagram of the structure of the auxiliary material stripping device shown in some embodiments of this specification.

In some embodiments, the feeding device 110 may include a feeding frame 111 and a rotating shaft 112. In some embodiments, the rotating shaft may be used to install the auxiliary material roll and drive the auxiliary material roll to rotate.

[0023] The auxiliary material roll 113 is a roll of auxiliary materials pasted on release paper. Release paper is industrial paper used to isolate sticky objects, and auxiliary materials refer to auxiliary consumables in the production process, for example, labels, double-sided tape, Mylar film, foam, conductive cloth, high-temperature glue, etc.

[0024] The conveying assembly 120 is a component for conveying the auxiliary material belt. In some embodiments, the conveying assembly 120 may include a conveying roller 121, and the conveying device drives the auxiliary material belt to perform a peeling operation by rotating the conveying roller. In some embodiments, a static elimination component is provided on the conveying roller. The static elimination component is used to eliminate static electricity on the auxiliary material belt.

[0025] The auxiliary material strip refers to an unrolled auxiliary material roll. In some embodiments, the auxiliary material strip may include release paper and cut auxiliary materials. The cut auxiliary materials refer to auxiliary materials cut by laser cutting.

[0026] The peeling assembly 130 is a assembly for peeling off the auxiliary material and the release paper. In some embodiments, the peeling assembly may include a limiting assembly 131 , a driving motor 132 , a separating assembly, and an adsorption assembly 134 .

[0027] The limiting assembly 131 is a assembly for limiting the position of the auxiliary material belt. In some embodiments, the limiting assembly can be arranged on both sides of the conveyor belt. For the description of the conveyor belt, please refer to the relevant description below.

[0028] The driving motor 132 is a component for driving the auxiliary material belt for conveyance.

[0029] The separation component is a component used to separate the auxiliary material from the release paper. Figure 1 As shown, the separation assembly may include a first shear sheet 133 - 1 and a second shear sheet 133 - 2 .

[0030] The first shearing piece 133-1 is used to peel the auxiliary material from the release paper. The second shearing piece 133-2 is used to separate the waste material attached to the inside of the auxiliary material from the auxiliary material. The waste material attached to the inside of the auxiliary material refers to the part that needs to be hollowed out inside the cut auxiliary material.

[0031] The adsorption component 134 is a component used to adsorb the peeled auxiliary material to prevent the auxiliary material from sticking to the first shearing sheet or the second shearing sheet. In some embodiments, the adsorption component is installed on the surface of the rotating shaft of the driving motor.

[0032] Figure 5 It is a partial cross-sectional schematic diagram of a stripping assembly according to some embodiments of the present specification.

[0033] like Figure 5 As shown, the cutout distance 501 between the first shearing sheet 133 - 1 and the second shearing sheet 133 - 2 refers to the shortest distance between the slicing edge of the first shearing sheet and the slicing edge of the second shearing sheet.

[0034] In some embodiments, the gap distance between the first shearing piece and the second shearing piece can be determined based on the appearance characteristics of the auxiliary material. For example, the peeling controller can set the gap distance according to the length of the auxiliary material, so that the auxiliary material enters the second shearing piece to remove the waste material only after it is completely peeled off by the first shearing piece. For another example, when the auxiliary material is an irregular shape, the technician can manually set the gap distance according to the appearance of the auxiliary material. For an explanation of the peeling controller, please refer to the relevant description below.

[0037] The stepper motor is a motor that provides power to the conveying device. In some embodiments, the conveyor belt performs stepping motion based on the stepper motor. For example, each time a piece of auxiliary material is peeled off, the stepper motor can rotate a fixed angle (i.e., step angle) in a set direction, and then stop to wait for the next piece of auxiliary material to be peeled off. The waiting time can be determined based on the stepping frequency. The stepping frequency refers to the frequency of the stepping motion of the stepper motor.

[0038] The stepping motion parameters are related parameters that reflect the operation of the stepping motor. For example, the stepping motion parameters may include stepping frequency, etc. In some embodiments, the stripping controller may adjust the stepping motion parameters of the stepping motor by adjusting the pulse signal output to the stepping motor.

[0039] In some embodiments, the stepping motion parameters of the stepping motor are synchronized with the driving parameters of the driving motor. For example, the stepping motor can monitor the operating state of the driving motor, determine the driving parameters, such as the speed of the driving motor, and determine the corresponding stepping motion parameters, such as the stepping frequency, based on the driving parameters, so that the stepping motion parameters are synchronized with the driving parameters.

[0043] In some embodiments, monitoring component 150 may include an image sensor.

[0044] Image sensor is a sensor used to obtain auxiliary material images. For example, the image sensor can be a CCD (Charge Coupled Device) image sensor, a CMOS (Complementary Metal-Oxide Semiconductor) image sensor, etc. For more information about auxiliary material images, please refer to Figure 3The corresponding description.

[0045] In some embodiments, the monitoring component may further include an adsorption force monitoring device.

[0046] The adsorption force monitoring device is a device for monitoring the adsorption process of the auxiliary material. In some embodiments, the adsorption force monitoring device may include a force sensor.

For more information about peeling pressure, see Figure 3 Related description.

[0048] The adjustment component is a component used to adjust the auxiliary material. In some embodiments, the adjustment component is disposed on the bracket and is used to adjust the auxiliary material posture. For example, the adjustment component may include a robotic arm, which can cooperate with the monitoring component to adjust the direction, position, angle, etc. of the auxiliary material to achieve the adjustment of the auxiliary material posture.

[0049] For more information about auxiliary material positions, see Figure 3 The corresponding description.

[0050] The stripping controller is a component for executing the auxiliary material stripping control method. In some embodiments, the stripping controller may include a processor and a wireless communication component. The wireless communication component is a component for realizing the interaction between the various components of the auxiliary material stripping device. In some embodiments, the wireless communication component can be connected to the feeding device, the static elimination component, the stripping component, the monitoring component, etc. to obtain relevant data and / or information.

[0051] The processor is used to process the data and information obtained by the wireless communication component. In some embodiments, the processor can control other devices of the auxiliary material stripping device (such as a feeding device, a conveying component, a stripping component, a monitoring component, an adjustment component, etc.) to execute program instructions based on the data, information and / or processing results obtained by the wireless communication component to execute the auxiliary material stripping control method.

[0052] In some embodiments, the processor may include one or more sub-processors. As an example only, the processor may be a central processing unit (CPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), etc., or any combination thereof.

For the relevant description of the first peeling quality, see Figure 4 The corresponding description.

[0057] In some embodiments of the present specification, the auxiliary material stripping device mentioned above can realize a more intelligent and automated auxiliary material stripping, the feeding device and the conveying component can automatically convey the auxiliary material belt and eliminate static electricity, the stripping component cooperates with the conveying device to separate and adsorb the auxiliary material, and the auxiliary material can be accurately and efficiently separated from the release paper, the monitoring component and the adjustment component can realize real-time monitoring and adjustment of the auxiliary material stripping process, and the stripping controller can control and adjust the entire auxiliary material stripping process.

[0058] Figure 2 It is an exemplary module diagram of an auxiliary material stripping control system shown in some embodiments of this specification.

[0059] In some embodiments, the auxiliary material stripping control system 200 may include a posture determination module 210 , an instruction sending module 220 , a drive adjustment module 230 and a step adjustment module 240 .

[0060] The posture determination module 210 is a module for determining the posture of the auxiliary material. In some embodiments, the posture determination module can be configured to determine the posture of the auxiliary material based on the auxiliary material image.

[0061] The instruction sending module 220 is a module for sending adjustment instructions. In some embodiments, the instruction sending module can be configured to send a first adjustment instruction to the adjustment component in response to the auxiliary material posture not meeting the posture requirement.

[0062] The driving adjustment module 230 is a module for adjusting driving parameters. In some embodiments, the driving adjustment module can be configured to adjust driving parameters of the driving motor.

[0063] The step adjustment module 240 is a module for adjusting the step motion parameters. In some embodiments, the step adjustment module can be configured to adjust the step motion parameters based on the driving parameters.

[0064] In some embodiments, the auxiliary material stripping control system 200 is further configured to determine a second stripping quality based on the stripping pressure; in response to the second stripping quality not meeting the quality requirement, send a second adjustment instruction to the adjustment component; and adjust the driving parameters and the stepping motion parameters.

[0065] In some embodiments, the auxiliary material peeling control system 200 is further configured to determine damage data of the auxiliary material based on the second peeling quality; and adjust the gap distance between the first shearing piece and the second shearing piece in response to the damage data satisfying a preset condition.

[0066] For detailed instructions on how to implement the above, see Figure 3 The corresponding description.

[0067] In some embodiments, the auxiliary material peeling control system 200 is further configured to evaluate the first peeling quality based on the auxiliary material image; determine the drive adjustment parameter based on the ambient temperature and the first peeling quality; and adjust the drive parameter of the drive motor based on the drive adjustment parameter. Figure 4 The corresponding description.

[0068] In some embodiments, all or part of the modules of the auxiliary material stripping control system can be integrated into the stripping controller. For relevant descriptions of the stripping controller, please refer to Figure 1 The corresponding description.

[0069] It should be noted that the above description of the auxiliary material stripping control system 200 and its modules is only for the convenience of description and does not limit the present specification to the scope of the embodiments. It is understandable that for those skilled in the art, after understanding the principle of the system, it is possible to arbitrarily combine the modules or form a subsystem to connect with other modules without deviating from this principle. In some embodiments, Figure 2The posture determination module 210, instruction sending module 220, drive adjustment module 230 and step adjustment module 240 disclosed in the specification can be different modules in a system, or a module can realize the functions of two or more modules mentioned above. For example, each module can share a storage module, or each module can have its own storage module. Such variations are all within the protection scope of this specification.

[0070] Figure 3 is an exemplary flow chart of the auxiliary material stripping control method shown in some embodiments of this specification. Figure 3 As shown, the process 300 includes the following steps. In some embodiments, the process 300 may be executed by a stripping controller.

[0071] Step 310: Determine the auxiliary material position and posture based on the auxiliary material image.

[0072] The auxiliary material image refers to the image of the auxiliary material after being peeled off by the peeling component. In some embodiments, the auxiliary material image can be obtained by an image sensor. For a description of the image sensor, see Figure 1 The corresponding description.

[0073] The auxiliary material posture refers to the orientation of the auxiliary material. For example, the auxiliary material posture can be characterized by the orientation angle of the auxiliary material relative to the peeling component, conveyor belt, etc.

[0074] In some embodiments, the stripping controller can determine the auxiliary material posture based on the auxiliary material image in a variety of ways. For example, the stripping controller can identify the auxiliary material and the stripping component in the auxiliary material image through an image recognition algorithm, and calculate the orientation angle of the auxiliary material relative to the conveyor belt to determine the auxiliary material posture.

[0075] Step 320: In response to the auxiliary material posture not meeting the posture requirement, a first adjustment instruction is sent to the adjustment component.

[0076] For instructions on adjusting components, see Figure 1 The corresponding description.

[0077] The posture requirement refers to the requirement for determining whether the posture of the auxiliary material is standard. In some embodiments, the posture requirement may be that the angle difference between the posture of the auxiliary material and the preset standard posture does not exceed a preset range. The standard posture and the preset range may be preset according to actual needs.

[0078] The first adjustment instruction is an instruction for adjusting the auxiliary material posture. For example, when it is found that the direction of the auxiliary material relative to the conveyor belt is opposite to the standard posture, the first adjustment instruction may be to rotate the auxiliary material 180 degrees clockwise / counterclockwise.

[0079] In some embodiments, the stripping controller may determine the first adjustment instruction in a variety of ways. For example, the stripping controller may determine the direction and angle amplitude to be adjusted based on the angle difference between the auxiliary material posture and the standard posture, and generate the corresponding first adjustment instruction.

[0080] In some embodiments, in response to the auxiliary material posture not meeting the posture requirement, the peeling controller may send a first adjustment instruction to the adjustment component, and the adjustment component adjusts the auxiliary material posture based on the adjustment direction and angle amplitude included in the first adjustment instruction.

[0081] Step 330: adjusting the driving parameters of the driving motor.

[0082] For more information about the drive motor, see Figure 1 The corresponding description.

[0083] The driving parameters are related parameters that reflect the operation of the driving motor. For example, the driving parameters may include the speed and power of the driving motor.

[0084] In some embodiments, when the adjustment component adjusts the auxiliary material posture based on the first adjustment instruction, the stripping controller can adjust the driving parameters of the drive motor. For example, the stripping controller can reduce the power of the drive motor and slow down the speed of the drive motor so that the adjustment component has enough time to adjust the auxiliary material posture.

[0085] Step 340 , adjusting the stepping motion parameters based on the driving parameters.

[0086] For more information about stepping motion parameters and stepping frequency, please refer to Figure 1 The corresponding description in .

[0087] In some embodiments, the peeling controller can adjust the stepping motion parameters in a variety of ways based on the driving parameters. For example, the peeling controller can calculate the time to complete the peeling of the next auxiliary material according to the adjusted driving parameters, thereby determining the time of the next stepping motion of the stepping motor, and adjusting the stepping frequency by adjusting the pulse signal input to the stepping motor.

[0088] In some embodiments of the present specification, by judging the auxiliary material posture based on the auxiliary material image, timely adjusting the auxiliary material that does not meet the posture requirements, and adjusting the driving parameters and stepping motion parameters at the same time, the operation of various components in the auxiliary material peeling process can be better coordinated to achieve a more intelligent auxiliary material peeling control method.

[0089] In some embodiments, the peeling controller is further configured to: determine a second peeling quality based on the peeling pressure; send a second adjustment instruction to the adjustment component in response to the second peeling quality not meeting the quality requirement; and adjust the driving parameters and the stepping motion parameters.

[0090] The peeling pressure refers to the maximum pressure required to peel the auxiliary material and the release paper. In some embodiments, the peeling pressure can be obtained by a force sensor. For details, see Figure 1 Related instructions.

[0091] The second peeling quality refers to the appearance quality of the auxiliary material when peeling. For example, the second peeling quality can be complete peeling, or damage, scratches, bending, folding, etc.

[0092] In some embodiments, the peeling controller can determine the second peeling quality based on the peeling pressure in a variety of ways. For example, the peeling controller can build a preset table based on historical data, and determine the second peeling quality by querying the preset table based on the peeling pressure. The preset table can include the corresponding relationship between the peeling pressure intervals of different auxiliary material types and the second peeling quality, and the second peeling quality corresponding to the different peeling pressures of different auxiliary materials in the historical data can be manually determined based on the appearance.

[0093] In some embodiments, the peeling controller may also obtain a peeling pressure curve of the peeling auxiliary material of the peeling component; and determine the second peeling quality based on the peeling pressure curve.

[0094] The peeling pressure curve is a continuous curve formed by the peeling pressure during the process of peeling a piece of auxiliary material.

[0095] In some embodiments, the peeling controller can determine the second peeling quality based on the peeling pressure curve in a variety of ways. For example, the peeling controller can match the peeling pressure curve in the peeling database based on the change trend and change process of the curve, obtain the reference peeling pressure curve with the highest similarity, and determine the reference second peeling quality corresponding to the reference peeling pressure curve as the second peeling quality of the auxiliary material corresponding to the peeling pressure curve.

[0096] Among them, the peeling database includes multiple reference peeling pressure curves and their corresponding second peeling qualities. The reference peeling pressure curve is composed of the peeling pressure curve generated when the auxiliary material is actually peeled off in the historical records. The corresponding second peeling quality can be determined based on the second peeling quality of the auxiliary material confirmed during manual quality inspection. The similarity can be obtained by calculating the Euclidean distance, dynamic time warping (DTW), correlation coefficient, etc. between the curves.

[0097] In some embodiments of the present specification, some minor internal damages during the auxiliary material peeling process may be difficult to see on the surface, but can be reflected in the peeling pressure curve. By determining the second peeling quality based on the peeling pressure curve, the peeling quality of the auxiliary material can be more accurately reflected, making the subsequent judgment on whether the second peeling quality meets the quality requirements more reliable.

[0098] The quality requirement is the appearance quality requirement when the auxiliary materials are peeled off. For example, the quality requirement may be that the auxiliary materials are completely peeled off.

[0099] The second adjustment instruction is an instruction for processing the auxiliary materials that do not meet the quality requirements. In some embodiments, the second adjustment instruction can be to directly discard the auxiliary materials that do not meet the quality requirements, or to move the auxiliary materials that do not meet the quality requirements aside for manual confirmation.

[0100] In some embodiments, in response to the second peeling quality not meeting the quality requirement, the peeling controller may send a second adjustment instruction to the adjustment component to process the auxiliary material that does not meet the quality requirement.

[0101] In some embodiments, when there are auxiliary materials that do not meet the quality requirements, the stripping controller can adjust the driving parameters to pause or slow down the driving motor and adjust the stepping motion parameters based on the driving parameters. For details on adjusting the stepping motion parameters based on the driving parameters, please refer to the relevant description of step 340 above.

[0102] In some embodiments of the present specification, by determining the second peeling quality based on the peeling pressure and sending the second adjustment instruction, the peeling quality of the auxiliary material can be judged more intelligently, so as to reasonably handle the auxiliary material that does not meet the quality requirements.

[0103] In some embodiments, the peeling controller is further configured to: determine damage data of the auxiliary material based on the second peeling quality; and adjust the gap distance between the first shearing piece and the second shearing piece in response to the damage data satisfying a preset condition.

[0104] For details about the first and second shears, see Figure 1 The corresponding description.

[0105] The damage data is data related to the damage of the auxiliary materials when the auxiliary materials are peeled off. For example, the damage data may be damage frequency, damage rate (i.e., the proportion of damaged auxiliary materials), etc.

[0106] In some embodiments, the stripping controller can determine the damage data based on the second stripping quality in a variety of ways. For example, the stripping controller can count the auxiliary materials with damaged second stripping quality, calculate the damage frequency of the auxiliary materials stripped in the recent period, or the damage rate of the auxiliary materials as a whole, to determine the damage data.

[0107] The preset condition is a condition related to the damaged data. In some embodiments, the preset condition may be that the damaged data exceeds a preset damage threshold. The preset damage threshold may be manually preset according to actual needs.

[0108] In some embodiments, in response to the damage data satisfying a preset condition, the peeling controller can adjust the gap distance between the first shearing piece and the second shearing piece in a variety of ways. For example, since a gap distance that is too small will increase the probability of damage, when the damage data meets the preset condition, the peeling controller can increase the gap distance according to the adjustment step length, and continuously monitor the subsequent second peeling quality through the monitoring component until the second peeling quality meets the quality requirements. Among them, continuously monitoring the subsequent second peeling quality through the monitoring component means that the peeling pressure in the subsequent auxiliary material peeling process is monitored by the force sensor of the monitoring component, and the corresponding second peeling quality is determined using the relevant method described above.

[0109] The adjustment step length refers to the amplitude of each adjustment of the sheet gap distance. In some embodiments, the adjustment step length can be preset manually or determined based on damage data, as described below.

[0110] For information about monitoring components and force sensors, see Figure 1 The corresponding description.

[0111] In some embodiments, the peeling controller can determine the adjustment step size of the sheet mouth distance based on the damage data; increase the sheet mouth distance based on the adjustment step size, and monitor the peeling pressure curve corresponding to the adjusted sheet mouth distance through a monitoring component; determine the peeling damage risk based on the peeling pressure curve; in response to the peeling damage risk exceeding the risk threshold, continue to increase the sheet mouth distance based on the adjustment step size until the peeling damage risk is lower than the risk threshold.

[0112] In some embodiments, the stripping controller may determine the adjustment step length of the gap distance based on the damage data in a variety of ways. For example, the adjustment step length may be positively correlated with the damage data.

[0113] In some embodiments, the adjustment step size may also be negatively correlated to the first peeling quality. For an explanation of the first peeling quality, see Figure 4 For example, the adjustment step length L can be calculated based on the following formula (1):

[0114] L=k1*S-k2*F (1)

[0115] Wherein, k1 and k2 are preset coefficients corresponding to the damage data and the first peeling quality, respectively, and k1 and k2 are positive values, S represents the damage data, and F represents the first peeling quality. When the calculated adjustment step length L is less than or equal to the preset minimum adjustment value, the adjustment step length is determined as the preset minimum adjustment value. The preset minimum adjustment value can be preset according to actual needs.

[0116] In some embodiments of the present specification, if the sheet mouth distance is too close, it may increase the damage. If the sheet mouth distance is too far, it may not be possible to effectively peel off the attached waste due to the long distance, resulting in poor first peeling quality. By considering the first peeling quality, the determined adjustment step size can be made more reasonable.

[0117] In some embodiments, the peeling controller can increase the gap distance based on the above-determined adjustment step length, and monitor the peeling pressure curve corresponding to the adjusted gap distance through the monitoring component. For example, the peeling controller can control the first shearing piece and the second shearing piece to increase the gap distance based on the adjustment step length, and monitor the peeling pressure during the peeling process of the auxiliary material after adjusting the gap distance through the force sensor of the monitoring component to determine the peeling pressure curve corresponding to the adjusted gap distance.

[0118] The peeling damage risk is data reflecting the risk of damage to the auxiliary material during peeling. For example, the peeling damage risk may be the probability of damage to the auxiliary material during peeling.

[0119] In some embodiments, the peeling controller may determine the peeling damage risk in a variety of ways based on the peeling pressure curve. For example, the peeling controller may determine the second peeling qualities corresponding to the plurality of reference peeling pressure curves by matching the plurality of reference peeling pressure curves in the peeling database based on the peeling pressure curve, calculate the proportion of the second peeling qualities that are damaged based on the plurality of second peeling qualities, and determine the proportion as the peeling damage risk.

[0120] In some embodiments, in response to the peeling damage risk exceeding the risk threshold, the peeling controller can continue to increase the sheet mouth distance based on the adjustment step length, and each time the sheet mouth distance is adjusted, the peeling controller can determine the corresponding peeling damage risk until the peeling damage risk is lower than the risk threshold, and then stop adjusting the sheet mouth distance. The risk threshold can be preset manually. The adjustment step length of each adjustment can be the same or different. The method for determining the adjustment step length is described in the above text, and the method for determining the peeling damage risk is described above.

[0121] In some embodiments of the present specification, a more reasonable adjustment step can be determined by adjusting the adjustment step of the sheet mouth distance based on damage data; damage may not occur immediately after adjusting the sheet mouth distance, but if the sheet mouth distance is inappropriate, the peeling pressure curve will have a certain manifestation. If the pressure curve is similar to the peeling pressure curve where more damage occurs, the risk of subsequent peeling damage is also greater. By monitoring the peeling pressure curve and adjusting the sheet mouth distance until the risk of peeling damage is lower than the risk threshold, damage in the subsequent peeling process can be better avoided.

[0122] In some embodiments of the present specification, by determining damage data based on the second peeling quality and then judging whether to adjust the sheet mouth distance, the sheet mouth distance can be adjusted more in line with the actual situation when necessary, thereby reducing the probability of damage.

[0123] It should be noted that the above description of process 300 is only for example and illustration, and does not limit the scope of application of this specification. For those skilled in the art, various modifications and changes can be made to process 300 under the guidance of this specification. However, these modifications and changes are still within the scope of this specification.

[0124] Figure 4 It is an exemplary schematic diagram of adjusting the driving parameters of the driving motor according to some embodiments of the present specification.

[0125] In some embodiments, Figure 4 As shown, the peeling controller is further configured to: evaluate the first peeling quality 430 based on the auxiliary material image 410; determine the driving adjustment parameter 450 based on the ambient temperature 440 and the first peeling quality 430; and adjust the driving parameter 460 of the driving motor based on the driving adjustment parameter 450.

[0126] For instructions on auxiliary material images and driver parameters, see Figure 3 The corresponding description.

[0127] The first peeling quality 430 is quality data related to the waste material attached to the auxiliary material. In some embodiments, the first peeling quality can be characterized by the amount of waste material remaining on the auxiliary material, the waste material area, etc.

[0128] In some embodiments, the stripping controller can evaluate the first stripping quality based on the auxiliary material image in a variety of ways. For example, the stripping controller can compare the auxiliary material image with a preset standard auxiliary material image, regard the area in the auxiliary material image that does not exist in the standard auxiliary material as the waste area, calculate the number of waste areas and the number of pixels in the auxiliary material image as the waste number and waste area in the first stripping quality, and thus determine the first stripping quality.

[0129] In some embodiments, Figure 4 As shown, the peeling controller may also determine a first peeling quality 430 through an effect model 420 based on the auxiliary material image 410 .

[0130] The effect model is a model for determining the first peeling quality. In some embodiments, the effect model may be a machine learning model. For example, the effect model may be a convolutional neural network model (CNN). In some embodiments, the input of the effect model may include an auxiliary material image, and the output may be the first peeling quality.

[0131] In some embodiments, the effect model can be obtained based on a large number of first training samples with first labels. The first training sample can be a sample auxiliary material image in the historical record, and the first label can be the historical actual first peeling quality of the auxiliary material corresponding to the sample auxiliary material image. In some embodiments, the waste material in the auxiliary material can be manually marked in the auxiliary material image, and then the waste material quantity and waste area in the marked sample auxiliary material image can be calculated by the peeling controller as the first label.

[0132] In some embodiments, the stripping controller may input a large number of sample auxiliary material images into the initial effect model, construct a loss function based on the output of the initial effect model and the label representing the actual first stripping quality of the sample auxiliary material image, and iteratively update the initial effect model based on the loss function; when the value of the loss function meets the iteration completion condition, the training is completed and a trained effect model is obtained. The iteration completion condition may include the convergence of the loss function, the number of iterations reaching a threshold, etc.

[0133] In some embodiments of the present specification, by using a large number of first training samples with first labels for training to obtain a trained effect model, the corresponding first peeling quality can be determined more efficiently and accurately based on the auxiliary material image.

[0134] The ambient temperature 440 refers to the temperature of the environment surrounding the auxiliary material when the auxiliary material is peeled off. In some embodiments, the ambient temperature can be obtained by a temperature sensor. For details, see Figure 1 Related instructions.

[0135] The driving adjustment parameter 450 refers to the parameter value after the driving parameter is adjusted.

[0136] In some embodiments, the stripping controller can determine the drive adjustment parameter based on the ambient temperature and the first stripping quality. For example, when the first stripping quality is poor, such as when the amount of waste material and the waste area exceed the historical average, the stripping controller can set the reduction value of the drive parameter based on the temperature difference between the ambient temperature and the preset ambient temperature, thereby determining the drive adjustment parameter. The greater the temperature difference, the greater the reduction value of the drive parameter, and the reduction value of the drive parameter cannot exceed the adjustment threshold. The temperature difference refers to the part of the ambient temperature that exceeds the preset ambient temperature, and the preset ambient temperature and the adjustment threshold can be preset according to actual conditions.

[0137] In some embodiments, in response to the first peeling quality not meeting the preset requirement, the peeling controller may retrieve the driving adjustment parameter from the parameter database based on the ambient temperature and the peeling pressure.

[0138] For more information on peeling pressure, see Figure 3 The corresponding description.

[0139] The preset requirement is used to determine whether the first peeling quality meets the requirement. In some embodiments, the preset requirement may be that the amount of waste or the area of ​​waste generated within a unit time period or unit peeling amount is less than a preset waste threshold. The preset waste threshold may be a preset waste amount threshold or a waste area threshold, which may be preset according to actual needs. In some embodiments, when the first peeling quality of the auxiliary material meets the preset requirement, the peeling controller may discard the auxiliary material, or move it aside for manual processing.

[0140] The parameter database is a database containing the correspondence between the ambient temperature, the peeling pressure and the driving parameters. In some embodiments, each combination of the ambient temperature and the peeling pressure corresponds to a set of driving parameters. In some embodiments, the parameter database can be constructed based on historical records. For example, the peeling controller can use the driving parameters with the highest first peeling quality after peeling the auxiliary material under similar ambient temperature and peeling pressure in the historical records as the driving parameters corresponding to the set of ambient temperature and peeling pressure in the parameter database.

[0141] In some embodiments, the peeling controller may retrieve the same or closest ambient temperature and peeling pressure in the parameter database and use the corresponding driving parameters as the driving adjustment parameters.

[0142] In some embodiments of the present specification, by constructing a parameter database and searching the parameter database based on the ambient temperature and the peeling pressure to determine the drive adjustment parameters, more appropriate drive parameters in different situations can be determined to improve the first peeling quality.

[0143] In some embodiments, the stripping controller may adjust the driving parameter to a corresponding value based on the driving adjustment parameter.

[0144] In some embodiments of the present specification, since the air volume and air speed of the cooling device will blow the auxiliary material and may affect the auxiliary material posture, the relevant parameters of the cooling device are not adjusted frequently. By evaluating the first peeling quality based on the auxiliary material image and determining appropriate drive adjustment parameters in combination with the ambient temperature to adjust the drive parameters, the peeling process can be monitored and adjusted in real time, reducing the impact of the ambient temperature on the first peeling quality, and making the first peeling quality of the auxiliary material peeling device more stable.

[0145] Some embodiments of the present specification also provide a computer-readable storage medium, which stores computer instructions. When a computer reads the computer instructions in the storage medium, the computer runs the auxiliary material stripping control method.
