[0002] The eyebrow pencil refill is the core part of the eyebrow pencil used to draw eyebrows.

[0003] At present, when eyebrow pencils are produced, a series of tests are usually required for the refills of the eyebrow pencils. In most cases, manual inspection is still relied on. The staff relies on experience and simple tools to check the appearance and color of the refills one by one.

[0004] However, manual inspection is greatly affected by subjective factors. Different quality inspectors have different judgment standards, which can easily lead to missed inspections and false inspections, resulting in the assembly of unqualified refills and nibs, thereby reducing the yield rate of eyebrow pencils.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Reference Figure 1 The present application embodiment discloses a control method for an eyebrow pencil refill detection mechanism, comprising the following steps: Step 100: Obtain pen tip image information of a preset pen tip detection area.

[0022] The pen tip detection area refers to the area used to detect the angle of the pen tip. The pen tip detection area is set in advance by a person skilled in the art and will not be described in detail here. The pen tip image information refers to the image of the pen tip contained in the pen tip detection area. The pen tip image information is obtained by taking a photo with a camera.

[0023] Step 101: Determine the pen tip angle value according to the pen tip image information, preset pen tip features and reference objects.

[0024] The pen tip feature refers to the features of the pen tip's appearance, outline, and color. The reference object refers to an object used to assist in measuring and comparing the actual position, size, and angle of each feature in the image. The position and size of the pen tip feature and the reference object are set in advance by those skilled in the art and will not be elaborated here. The pen tip angle value refers to the angle value that the pen tip currently presents relative to the horizontal direction. By identifying the size and angle of the pen tip feature and the reference object in the pen tip image information, and then comparing the actual size and angle of the reference object, the ratio between the parameters in the image and the actual parameters can be known, and then the actual pen tip angle value of the pen tip can be obtained.

[0025] Step 102: When the pen tip angle value is inconsistent with a preset reference angle value, an angle adjustment value is determined according to the pen tip angle value and the reference angle value.

[0026] The reference angle value refers to the angle value that the pen tip should be at. The reference angle value is set in advance by a person skilled in the art and will not be described in detail here. The angle adjustment value refers to the specific value when the pen tip is adjusted in angle. The angle adjustment value can be known by calculating the difference between the pen tip angle value and the reference angle value. When the pen tip angle value is inconsistent with the reference angle value, it means that the current angle of the pen tip is abnormal, and the angle adjustment value must be calculated first for subsequent steps.

[0027] Step 103: Based on the angle adjustment value, a preset angle adjustment device is controlled to adjust the angle of the pen tip, and after the angle adjustment is completed, the pen core is inserted using a preset pen core insertion method.

[0028] The angle adjustment device refers to a device for adjusting the angle of the pen tip. The refill insertion method refers to a method for inserting the refill into the pen tip. The specific refill insertion method is described in detail in the subsequent steps 200 to 205, and will not be repeated here.

[0029] The angle adjustment device is controlled to adjust the angle of the pen tip according to the angle adjustment value, and after the angle adjustment of the pen tip is completed, the pen core is inserted into the pen tip by the pen core insertion method.

[0030] Step 104: After the refill is inserted, a preset refill detection device is controlled to perform fracture detection on the refill using a preset fracture detection method, and a fracture detection signal is obtained.

[0031] The refill detection device refers to a device for detecting whether the refill inserted into the pen tip is broken. The fracture detection method refers to a method for detecting whether the refill inserted into the pen tip is broken. The fracture detection method is described in detail in the subsequent steps 300 to 306, which will not be described in detail here. The fracture detection signal refers to the detection result output by the refill detection device after the refill is detected for fracture. The fracture detection signal includes a qualified detection signal and an abnormal detection signal. The qualified detection signal refers to the signal when the refill inserted into the pen tip is not broken. The abnormal detection signal refers to the signal when the refill inserted into the pen tip is broken. The qualified detection signal and the abnormal detection signal are both set in advance by those skilled in the art, which will not be described in detail here. The fracture detection signal is obtained by a signal transceiver preset on the refill detection device.

[0032] After the refill is inserted into the pen tip, the refill detection device needs to be controlled to perform fracture detection on the refill using a fracture detection method, and then a fracture detection signal is obtained for subsequent steps.

[0033] Step 105: When the fracture detection signal is consistent with the preset qualified detection signal, the pen cap is installed using a preset pen cap installation method, thereby completing the installation of the eyebrow pencil.

[0034] The pen cap installation method refers to a method for installing and fixing the pen cap and the pen tip. The specific pen cap installation method is described in detail in the subsequent steps 400 to 406, and will not be repeated here.

[0035] When the fracture detection signal is consistent with the qualified detection signal, it indicates that the pen core is not broken, and the pen cap can be directly installed on the pen tip in the same way as the pen cap installation method, thereby completing the installation of the eyebrow pencil.

[0036] Reference Figure 2, the refill insertion method comprises the following steps: Step 200: Obtaining the refill image information of the preset refill placement area.

[0037] The refill placement area refers to an area for placing the refill to be loaded into the pen tip. The refill placement area is set in advance by a person skilled in the art and will not be described in detail here. The refill image information refers to an image of the refill in the refill placement area. The refill image information is obtained by taking a photo with a camera.

[0038] Step 201: Determine the position of the pen core according to the pen core image information, the preset pen core features and the reference object.

[0039] The refill features refer to the features of the refill's appearance, outline, and color. The refill features are set in advance by those skilled in the art and will not be described in detail here. The refill position refers to the position of the refill within the qualified refill area. The qualified refill area refers to the area used to place refills that have passed the inspection. The qualified refill area is set in advance by those skilled in the art and will not be described in detail here. By identifying the positions of the refill features and the reference object in the refill image information, and then comparing the actual position of the reference object, the proportion of the image can be known, and then the actual refill position can be compared.

[0040] Step 202: Control a preset clamping device according to the position of the pen core to clamp the pen core into a preset pen core placement device.

[0041] The clamping device is a device used to clamp the refill in the qualified refill area into the refill placement device. The refill placement device is a device used to place the refill to be inserted into the nib. Before the refill is inserted into the nib, the refill needs to be placed on the refill placement device.

[0042] The clamping device is controlled to move to the position just above the pen core to clamp the pen core into the pen core placement device for subsequent steps.

[0043] Step 203: Obtain the insertion image information of the preset insertion area.

[0044] The insertion area refers to the area where the pen core is inserted into the pen tip. The insertion area is set in advance by a person skilled in the art and will not be described in detail here. The insertion image information refers to the image in the insertion area. The insertion image information is obtained by taking a photo with a camera.

[0045] Step 204: When the insertion image information does not contain the preset refill placement device feature, control the clamping device to clamp the refill placement device into the insertion area.

[0046] The characteristics of the refill placement device refer to the characteristics of the appearance, outline and color of the refill placement device. The characteristics of the refill placement device are set in advance by those skilled in the art and will not be described in detail here.

[0047] When the insertion image information does not contain the refill placement device feature, it means that there is no refill placement device in the insertion area, and the clamping device can be controlled to clamp the refill placement device into the insertion area for subsequent steps.

[0048] Step 205: Control the preset propulsion device to push the refill in the refill placement device into the pen tip with a preset propulsion force value.

[0049] The propulsion device refers to a device for pushing the refill in the refill placement device into the pen tip. The propulsion force value refers to the force value when the propulsion device pushes the refill in the refill placement device into the pen tip. The propulsion force value is set in advance by a person skilled in the art and will not be described in detail here.

[0050] The propulsion device is controlled to push the pen core in the pen core placement device into the pen tip according to the propulsion force value, thereby completing the process of inserting the pen core into the pen tip.

[0051] Reference Figure 3 , the fracture detection method comprises the following steps: Step 300: After the pen core is pushed into the pen tip, push-in image information of a preset push-in detection area is obtained.

[0052] The push-in detection area refers to the area used to detect whether the pen core is inserted into the pen tip. The push-in detection area is set in advance by a person skilled in the art and will not be described in detail here. The push-in image information refers to the image in the push-in detection area. The push-in image information is obtained by taking a photo with a camera.

[0053] After the pen core is pushed into the pen tip, it is necessary to obtain the push-in image information of the push-in detection area for subsequent steps.

[0054] Step 301: Based on the fact that the push-in image information contains the refill feature, the refill detection device is controlled to clamp the refill with a preset clamping force value, and after clamping, the refill is pulled with a preset pulling force value, and after a preset pulling distance value, a rebound pressure value is obtained.

[0055] The clamping force value refers to the force value when the refill detection device clamps the refill. The pulling force value refers to the force value when the refill detection device performs pulling detection after clamping the refill. The pulling distance value refers to the distance the refill detection device pulls when performing pulling detection after clamping the refill. The clamping force value, pulling force value and pulling distance value are all set in advance by those skilled in the art and will not be elaborated here. The rebound pressure value refers to the pressure value that the refill detection device is subjected to when it rebounds after the refill detection device pulls the refill with the pulling force value. The rebound pressure value is measured by a preset pressure sensor on the refill detection device.

[0056] In this embodiment, there are two parallel rubber bands on the refill detection device. The two rubber bands are close to each other to clamp the refill, and after clamping the refill, they are pulled in the direction away from the pen tip. When pulled to a pulling distance value, the rubber band will rebound and reset. By understanding the rebound pressure value, the breakage of the refill can be known.

[0057] When the push-in image information contains the refill feature, it means that the refill has been successfully inserted into the pen tip. The refill detection device needs to be controlled to clamp the refill with the clamping force value, and after clamping, the refill is pulled with the pulling force value. After the refill detection device moves the pulling distance value, the rebound pressure value of the refill detection device is obtained for subsequent steps.

[0058] Step 302: When the rebound pressure value is lower than a preset reference pressure value, device image information of the refill detection device is obtained.

[0059] The reference pressure value refers to the force value that the rebound pressure value should reach. The reference pressure value is set in advance by a person skilled in the art and will not be described in detail here. The device image information refers to the image of the outer surface of the refill detection device, and the device image information includes two rubber bands on the refill detection device. The device image information is obtained by taking a photo with a camera.

[0060] When the rebound pressure value is lower than the reference pressure value, it indicates that the pen core may be broken during the fracture detection of the pen core, and it is necessary to obtain device image information of the pen core detection device to further verify the result of the fracture detection.

[0061] Step 303: Determine the size of the rubber band according to the device image information, the preset rubber band features and the reference object.

[0062] The rubber band features refer to the features of the appearance, outline and color of the two rubber bands on the refill detection device. The rubber band features are set in advance by those skilled in the art and will not be described in detail here. The rubber band size refers to the size of the rubber band. By identifying the rubber band features and the size of the reference object in the device image information, and then comparing the actual size of the reference object, the ratio between the parameters in the image and the actual parameters can be known, and then the actual rubber band size of the rubber band can be obtained.

[0063] Step 304: When the rubber band size is inconsistent with the preset reference rubber band size, a corrected pressure value is determined according to the rubber band size, the reference rubber band size and the reference pressure value.

[0064] The reference rubber band size refers to the size that the rubber band should be. The reference rubber band size is set in advance by a person skilled in the art and will not be described in detail here. The corrected pressure value refers to the corrected reference pressure value. Since the size of the rubber band deviates, the reference pressure value will also deviate accordingly, and then the preset pressure database is required to match the rubber band size, the reference rubber band size and the corrected pressure value corresponding to the reference pressure value, so as to further verify the result of the fracture detection. The pressure database contains the correspondence between the rubber band size, the reference rubber band size, the reference pressure value and the corrected pressure value. The pressure database is a manually set database and will not be described in detail here.

[0065] When the size of the rubber band is inconsistent with the reference rubber band size, it means that the rubber band is worn, which further indicates that there is a deviation in the detection result in step 302, and a corrected pressure value needs to be matched first for subsequent steps.

[0066] Step 305: When the rebound pressure value is lower than the correction pressure value, an abnormal detection signal is reported.

[0067] When the rebound pressure value is lower than the correction pressure value, it means that the pen core is broken and an abnormal detection signal needs to be reported.

[0068] Step 306: When the rebound pressure value is not lower than the correction pressure value, a qualified detection signal is reported.

[0069] When the rebound pressure value is lower than the correction pressure value, it means that the pen core is not broken and a qualified detection signal needs to be reported.

[0070] Reference Figure 4 , the pen cap installation method includes the following steps: Step 400: Obtain installation image information of a preset pen cap installation area.

[0071] The pen cap installation area refers to the area for installing the pen cap on the pen tip. The pen cap installation area is set in advance by a person skilled in the art and will not be described in detail here. The installation image information refers to the image in the pen cap installation area. The installation image information is obtained by taking a picture with a camera.

[0072] Step 401: Determine the pen tip position according to the installation image information, pen tip features and reference objects.

[0073] The pen tip position refers to the position of the pen tip within the pen cap installation area. By identifying the pen tip features and the position of the reference object in the device image information, and then comparing the actual position of the reference object, the ratio between the parameters in the image and the actual parameters can be known, and the pen tip position can be compared.

[0074] Step 402: Determine the pen cap placement position according to the pen tip position and a preset pen cap placement device model.

[0075] The model of the pen cap placement device refers to the specific model of the pen cap placement device. The pen cap placement device refers to a device used to place the pen cap and enable the pre-installation device to pre-install the pen cap on the pen tip. The pre-installation device refers to a device used to pre-install the pen cap on the pen tip. The pen cap placement device has multiple placement slots for placing the pen cap. By understanding the model of the pen cap placement device, the specific position of each placement slot on the device can be known. The model of the pen cap placement device is selected in advance by a person skilled in the art and will not be described in detail here.

[0076] The pen cap placement position corresponding to the pen tip position and the pen cap placement device position can be matched through the preset position database, which includes the correspondence between the pen tip position, the pen cap placement device position and the pen cap placement position. The position database is an artificially set database and will not be elaborated here.

[0077] Step 403: Control a preset clamping device to clamp the pen cap to a pen cap placement position, and obtain pen cap material information and pen tip material information.

[0078] The clamping device refers to a device used to clamp the pen cap to the pen cap placement position. The pen cap material information refers to the material used to manufacture the pen cap. The pen tip material information refers to the material used to manufacture the pen tip. The pen cap material information and the pen tip material information can be retrieved from the preset material database. The material database stores the pen cap material information and the pen tip material information. The material database is a manually set database and will not be described in detail here.

[0079] First, control the clamping device to clamp the pen cap to the pen cap placement position, and then obtain the pen cap material information and the pen tip material information for subsequent steps.

[0080] Step 404: Determine the applied static electricity value according to the pen cap material information and the pen tip material information.

[0081] The applied static value refers to the static value achieved when the pen cap and pen tip are subjected to static electricity. The applied static value corresponding to the pen cap material information and the pen tip material information can be matched through the preset static database, which contains the correspondence between the pen cap material information, the pen tip material information and the applied static value. The static database is a manually set database and will not be described in detail here.

[0082] Step 405: Based on the applied static electricity value, a preset static electricity device is controlled to apply static electricity to the pen cap and the pen tip, and a preset pre-installation device is controlled to pre-install the pen cap on the pen tip with a preset pre-installation force value.

[0083] The electrostatic device refers to a device for applying static electricity to the pen cap and the pen tip. The pre-installation force value refers to the force value used when the pre-installation device pre-installs the pen cap on the pen tip. The pre-installation force value is set in advance by a person skilled in the art and will not be described in detail here.

[0084] The electrostatic device is controlled to apply static electricity to the pen cap and the pen tip with an applied static electricity value, so as to increase the adsorption capacity between the pen cap and the pen tip, and then the pre-installation device is controlled to pre-install the pen cap on the pen tip with a pre-installation force value for subsequent steps.

[0085] Step 406: After the pre-installation is completed, the preset propulsion device is controlled to propel the pen cap with a preset propulsion strength value, thereby completing the installation of the pen cap.

[0086] The pushing device refers to a device used to completely install the pen cap on the pen tip. The pushing strength value refers to the force value used by the pushing device when the pen cap is completely installed on the pen tip. The pushing strength value is set in advance by a person skilled in the art and will not be described in detail here.

[0087] After the pre-installation is completed, the propulsion device needs to be controlled to propel the pen cap with a propulsion strength value, so as to completely install the pen cap on the pen tip, thereby completing the installation of the pen cap.

[0088] Reference Figure 5 , further comprising the step of controlling a preset propulsion device to propel the pen cap with a preset propulsion strength value before: Step 500: Acquire advancement image information.

[0089] The advancing image information refers to the image before the advancing device advances the pen cap. The advancing image information is obtained by taking a picture with a camera.

[0090] Step 501: Determine the current posture of the pen cap according to the advancement image information and preset pen cap features.

[0091] The current posture of the pen cap refers to the posture of the pen cap pre-installed on the pen tip before the propulsion device propels the pen cap. The current posture of the pen cap corresponding to the pen cap features in the image propulsion information can be matched through the preset posture database, which contains the corresponding relationship between the propulsion image information and the pen cap features and the current posture of the pen cap. The posture recognition library is a manually set database and will not be described here.

[0092] Step 502: When the current posture of the pen cap is consistent with the preset pen cap detachment posture, the pen cap detachment parameters are determined according to the propulsion image information, the pen tip features, the pen cap features and the reference object.

[0093] The pen cap detachment posture refers to the posture of the pen cap when it is tilted on the pen tip and is about to detach from the pen tip. The pen cap detachment posture is set in advance by a person skilled in the art and will not be described in detail here. The pen cap detachment parameter refers to the angle value when the pen cap is tilted and the distance value of the pen cap sliding off the pen tip due to the tilt of the pen cap. The pen cap detachment parameters corresponding to the propulsion image information, pen tip features, pen cap features and reference objects can be matched through the preset detachment database, which includes the corresponding relationship between the propulsion image information, pen tip features, pen cap features, reference objects and pen cap detachment parameters. The detachment database is a manually set database and will not be described in detail here.

[0094] When the current posture of the pen cap is consistent with the pen cap detachment posture, it means that there is an abnormality in the pre-installation of the pen cap, and the pen cap is about to detach from the pen tip. In order to avoid damage to the pen cap and the pen tip during further fixing operations, the pen cap detachment parameters need to be matched first for subsequent steps.

[0095] Step 503: Determine the lifting height value and the displacement angle value according to the pen cap detachment parameter.

[0096] The lifting height value refers to the height value when the pen cap is lifted. The displacement angle value refers to the angle value of the displacement during the process of pushing the pen cap back to the pre-installed state while the pen cap is lifted. The lifting height value and displacement angle value corresponding to the pen cap detachment parameter can be matched through the preset lifting database, which includes the correspondence between the pen cap detachment parameter, the lifting height value and the displacement angle value. The lifting database is a manually set database and will not be described here.

[0097] Step 504: Determine the current intensity value and the device angle value according to the lifting height value, the displacement angle value, and the preset device spacing distance value.

[0098] The device spacing distance value refers to the distance between the electromagnetic mutual repulsion device and the pen cap in the pre-installed state. The device spacing distance value is set in advance by a person skilled in the art and will not be described in detail here. The current intensity value refers to the intensity value of the electromagnetic mutual repulsion device when applying current to the pen cap. The device angle value refers to the angle value presented by the electromagnetic mutual repulsion device relative to the horizontal direction when applying current to the pen cap. The electromagnetic mutual repulsion device refers to a device that generates electromagnetics by energizing and uses the mutual repulsion between electromagnetics to achieve the effect of lifting the pen cap.

[0099] The lifting database can be used to match the current intensity value and device angle value corresponding to the lifting height value, the shifting angle value and the device spacing distance value, which includes the corresponding relationship between the lifting height value, the shifting angle value, the device spacing distance value, the current intensity value and the device angle value.

[0100] Step 505: Control the preset electromagnetic repulsion device to be adjusted to be consistent with the device angle value, and energize it with the current intensity value to lift and reset the pen cap.

[0101] The electromagnetic mutual repulsion device is controlled to adjust the angle to be consistent with the device angle value, and after consistency, the electromagnetic mutual repulsion device is controlled to be energized with the current intensity value, so as to utilize the mutual repulsion force between the electromagnetics to lift and reset the pen cap.

[0102] Reference Figure 6 , the refill detection method comprises the following steps: Step 600: Acquire detection image information of a preset refill detection area and refill material information.

[0103] The refill detection area refers to the area used to detect whether the refill is damaged. The refill detection area is set in advance by a person skilled in the art and will not be described in detail here. The detection image information refers to the image in the refill detection area. The detection image information is obtained by taking a photo with a camera. The refill material information refers to the material used in manufacturing the refill.

The current posture of the refill corresponding to the refill feature in the detection image information can be matched through the posture database, which includes the corresponding relationship between the detection image information, the refill feature and the current posture of the refill.

[0106] Step 602: When the current posture of the pen core is inconsistent with the preset reference detection posture, determine the posture adjustment angle value according to the current posture of the pen core and the reference detection posture.

[0107] The reference detection posture refers to the placement posture that the pen core should be in on the pen core detection area. The reference detection posture is set in advance by a person skilled in the art and will not be elaborated here. The posture adjustment angle value refers to the rotation angle when adjusting the placement posture of the pen core. The posture adjustment angle value corresponding to the current posture of the pen core and the reference detection posture can be matched through a preset adjustment database, which includes the corresponding relationship between the current posture of the pen core and the reference detection posture and the posture adjustment angle value. The adjustment database is an artificially set database and will not be elaborated here.

[0108] Step 603: Based on the posture adjustment angle value, the preset posture adjustment device is controlled to adjust the posture of the pen core. After the adjustment, the clamping device is controlled to clamp the pen core into the preset blowing detection device, and the blowing detection device is controlled to close.

[0109] The posture adjustment device refers to a device used to adjust the placement posture of the pen refill. The blowing detection device refers to a device that detects the damage of the pen refill by blowing air. After the pen refill is placed in the blowing detection device, the blowing detection device will be closed immediately so that the pen refill will not be affected by the external environment wind when the blowing detection is performed later.

[0110] The posture adjustment device is controlled to adjust the posture of the pen core with the posture adjustment angle value, and after the adjustment is completed, the clamping device is controlled to clamp the pen core into the blowing detection device, and the blowing detection device is controlled to close for subsequent steps.

[0111] Step 604: After the blowing detection device is closed, the pen core is blown with a preset blowing force value, and the blowing pressure distribution and the internal temperature value of the blowing detection device are obtained.

[0112] The blowing force value refers to the force value when the blowing detection device blows air to the pen core. The blowing force value is set in advance by a person skilled in the art and will not be described in detail here.

The pressure distribution plate is arranged in the blowing detection device, and a plurality of pressure sensors are evenly arranged on the pressure distribution plate, and each sensor is provided with a corresponding number. The blowing pressure distribution can be analyzed by inputting the pressure value of the pressure sensor corresponding to the number into a preset distribution database. The distribution database stores the corresponding relationship between each pressure sensor on the pressure distribution plate and the blowing pressure distribution. The distribution database is an artificially set database and will not be described in detail here. The internal temperature value refers to the temperature value inside the blowing detection device. The internal temperature value is obtained by measuring the preset temperature sensor in the blowing detection device.

[0113] When the blowing detection device is closed, the blowing detection device is controlled to blow air to the pen core with the blowing force value, and the blowing pressure distribution and the internal temperature value of the blowing detection device are obtained for subsequent steps.

[0114] Step 605: Determine the reference pressure distribution according to the refill material information, preset refill parameters and internal temperature value.

[0115] The refill parameters refer to the size, weight and outer contour of the refill under qualified conditions. The refill parameters are set in advance by those skilled in the art and will not be described in detail here. The reference pressure distribution refers to the situation where the blowing pressure distribution should be. The reference pressure distribution corresponding to the refill material information, refill parameters and internal temperature values ​​can be matched through the distribution database, which includes the corresponding relationship between the refill material information, refill parameters, internal temperature values ​​and reference pressure distribution conditions.

[0116] Step 606: When the reference pressure distribution is inconsistent with the blowing pressure distribution, a tip indicating that the pen core is damaged is reported.

[0117] The pen core damage prompt refers to the prompt when the outer surface of the pen core is damaged. The pen core damage prompt is set in advance by those skilled in the art and will not be described in detail here.

[0118] When the reference pressure distribution is inconsistent with the blowing pressure distribution, it means that the outer surface of the pen core is damaged and the pen core damage prompt needs to be reported.

[0119] Reference Figure 7 , the detection and verification method includes the following steps: Step 700: When the reference pressure distribution is consistent with the blowing pressure distribution, the blowing detection device is controlled to open, and the friction coefficient of the pen core is determined according to the pen core material information and the preset desktop material.

[0120] The desktop material refers to the material of the desktop used to place the pen refill. The desktop material is set in advance by a person skilled in the art and will not be described in detail here. The pen refill friction coefficient refers to the friction coefficient between the pen refill and the desktop. The pen refill friction coefficient corresponding to the pen refill material information and the desktop material can be matched through a preset friction database, which contains the correspondence between the pen refill material information, the desktop material and the pen refill friction coefficient. The friction database is a manually set database and will not be described in detail here.

[0121] When the reference pressure distribution is consistent with the blowing pressure distribution, it means that the outer surface of the pen core currently subjected to the blowing test is not damaged, and subsequent tests can be carried out. The blowing detection device can be directly controlled to close the closed state, and then the friction coefficient of the pen core can be matched for subsequent steps.

[0122] Step 701: Determine the blowing wind force value according to the pen core friction coefficient, the pen core parameters and the preset moving distance value.

[0123] The moving distance value refers to the distance value that needs to be blown to move the pen core. The moving distance value is set in advance by those skilled in the art and will not be described in detail here. The blowing wind force value refers to the wind force value when blowing the pen core. m g+m (v 2 / 2s) k can be used to calculate the wind force value, where F is the wind force value, μ is the friction coefficient of the pen core, m is the weight of the pen core in the pen core parameters, g is the acceleration of gravity, v is the final speed when the pen core is blown away by the moving distance value, s is the moving distance value, and k is the correction coefficient. v, g and k are all measured in advance by those skilled in the art and will not be described in detail here.

[0124] Step 702: Determine the maximum wind force value according to the blowing wind force value and the preset remaining distance value.

[0125] The remaining distance value refers to the remaining distance value between the position of the pen core and the preset abnormal pen core area after the pen core moves by the moving distance value. The abnormal pen core area refers to the area used to concentrate unqualified pen cores. The remaining distance value and the abnormal pen core area are both set in advance by those skilled in the art and will not be described in detail here. The maximum wind force value refers to the wind force value required to blow the pen core into the abnormal pen core area. The maximum wind force value corresponding to the blowing wind force value and the remaining distance value can be matched through the preset blowing database, which includes the corresponding relationship between the blowing wind force value and the remaining distance value and the maximum wind force value. The blowing database is a manually set database and will not be described in detail here.

[0126] Step 703: Based on the blowing wind force value, a preset blowing device is controlled to blow air to the pen core, and blowing image information is obtained.

[0127] The blowing device refers to a device for blowing the pen core to a preset pen core arrival position. The pen core arrival position refers to the position that the pen core should reach after moving by the moving distance value. The pen core arrival position is set in advance by those skilled in the art and will not be described in detail here. The blowing image information refers to the image of the pen core after being blown. The blowing image information is obtained by taking a picture with a camera.

[0128] The blowing device is controlled to blow air to the pen core at a blowing wind force value, and blowing image information is obtained after blowing for subsequent steps.

[0129] Step 704: Determine whether the refill feature falls within the preset refill arrival position feature based on the blowing image information.

[0130] The refill arrival position feature refers to the appearance feature of the refill arrival position. The refill arrival position feature is set in advance by a person skilled in the art and will not be described in detail here. The refill arrival position feature has a larger feature range than the refill feature.

[0131] By judging whether the refill feature in the blowing image information falls on the refill arrival position feature, it can be known whether the distance the refill is blown away is abnormal, and further whether other parts of the refill are damaged.

[0132] Step 705: When the refill feature does not fall on the refill arrival position feature, the blowing device is controlled to blow the refill into a preset abnormal refill area at a maximum wind force value.

[0133] When the refill feature does not fall into the refill arrival position feature, it indicates that the distance the refill is blown away is abnormal, which further indicates that the refill is damaged in other parts. The blowing device needs to be controlled to blow the refill into the abnormal refill area at the maximum wind force.

[0134] Step 706: Based on the refill feature falling onto the refill arrival position feature, control the preset pushing device to push the refill into the preset qualified refill area.

[0135] The push device is a device used to push a qualified refill into the qualified refill area. When the refill feature falls on the refill arrival position feature, it means that the distance the refill is blown away is normal, and further indicates that there is no damage to other parts of the refill. The push device can be directly controlled to push the refill into the qualified refill area for subsequent use.
