Description

Technical Field

[0001] The present invention relates to the field of mechanical manufacturing, and in particular to a manufacturing method, system and terminal of a mechanical intermittent motion valve. Background Art

[0002] The mechanical intermittent motion valve is a special mechanical valve that combines the functional characteristics of an intermittent motion mechanism and a mechanical valve, and can be opened and closed at predetermined time intervals or periodically.

[0003] The mechanical intermittent motion valve mainly includes a dynamic valve driven by a motor and a fixed static valve. The dynamic valve has an air path for high-pressure airflow, and the static valve also has an air path. When the motor drives the dynamic valve to rotate on the surface of the static valve, the dynamic valve is opened when the air paths of the two are connected.

[0004] Mechanical intermittent motion valves are commonly used for intermittent control of pneumatic motors and are used in automobile wipers. Mechanical intermittent motion valves usually have metal valve bodies. After casting, burrs may be present in the air passage. When the mechanical intermittent motion valve is in use, the burrs may be rushed into the pneumatic motor along with the high-pressure airflow, which may easily cause the pneumatic motor to malfunction. Therefore, the burrs in the mechanical intermittent motion valve need to be removed. In most factories, burr removal is usually done manually, with workers using metal brushes to clean the air passages. This process is inefficient and the burr removal is not comprehensive, so burrs may still remain in the air passages, which needs to be improved. Summary of the Invention

[0005] In order to improve the efficiency of removing burrs from a mechanical intermittent motion valve, the present invention provides a method, system and terminal for manufacturing a mechanical intermittent motion valve.

[0006] In a first aspect, the present invention provides a method for manufacturing a mechanical intermittent motion valve, which adopts the following technical solution: A method for manufacturing a mechanical intermittent motion valve, comprising: Acquire an image of the internal gas path of a moving valve in an intermittent motion valve; Generate an airway channel model based on the internal airway image; Compare and analyze the gas path channel model with the preset reference model to determine the burr characteristics and burr feature locations; Determine the burr diameter of each burr feature according to the gas path model and the burr feature position; Compare each burr feature to determine the burr feature with the largest burr diameter, and determine the maximum burr diameter; Match the shock wave intensity of the preset high-pressure air release device according to the maximum burr diameter; According to the intensity of the shock wave, the high-pressure air release device is controlled to release the air shock wave to the air path of the intermittent motion valve to break the burr feature and blow it out of the intermittent motion valve.

[0007] By adopting the above technical solution, a shock wave of high-pressure air is released into the air path of the motion valve, and the burr features in the air path are broken by the shock wave. After breaking, the burr features can be blown out of the motion valve by the air flow, thereby achieving the effect of clearing the burr features. The above-mentioned efficiency of clearing burrs in the motion valve is relatively high.

[0008] Optionally, the intensity of the shock wave will be attenuated when propagating in the air path, so it is necessary to correct the intensity of the shock wave of the high-pressure air released by the high-pressure air release device. The shock wave intensity correction method includes: Determine the blocking surface area of ​​each burr feature according to the gas path model and the burr features, and determine the total blocking area of ​​all burr features; Determine the influence distance of the burr feature with the largest blocking surface area from the gas channel entrance and the distal burr diameter of the burr feature farthest from the gas channel entrance according to the gas channel model and the burr feature position; Determine the regional blocking area of ​​all burr features in the gas path that affect the distance based on the affected distance; Determine the regional attenuation of the shock wave according to the regional blocking area, and calculate the sum of the regional attenuation and the shock wave intensity to be defined as the regional shock wave intensity; Matching the distal shock wave intensity of the burr feature farthest from the gas channel entrance to the distal burr diameter; Determine the far-end attenuation of the shock wave according to the total blocking area, and calculate the sum of the far-end attenuation and the shock wave intensity to be defined as the penetration shock wave intensity; Based on the regional shock wave intensity being greater than the penetrating shock wave intensity, the regional shock wave intensity is used as a modified shock wave intensity and the modified shock wave intensity is output; Based on the regional shock wave intensity being no greater than the penetrating shock wave intensity, the penetrating shock wave intensity is used as a corrected shock wave intensity and the corrected shock wave intensity is output.

[0009] Optionally, the shock wave intensity correction method further includes: Determine the total length of the gas path according to the gas path model; Determine the gas path bending characteristics and total bending angle based on the gas path channel model; Determine the friction attenuation according to the total length of the gas path and the preset channel friction coefficient; Determine the total bending attenuation according to the total bending angle; The final shock wave intensity is determined based on the corrected shock wave intensity, friction attenuation, and total bending attenuation.

[0010] Optionally, after the burr feature is blown off, it may fall into the gap between the moving valve and the static valve of the intermittent motion valve, causing the gap to widen and leak. Methods for handling the burr feature in the gap include: The intermittent motion valve is controlled to rotate at a preset centrifugal speed; After a preset centrifugation time, obtaining image information of the gap between the dynamic valve and the static valve at the connection point of the gas passage; Determine the gap width between the dynamic valve and the static valve according to the gap image information, and determine the maximum gap width position according to the gap width; Determine the concentrated location of burr features based on the maximum gap width; Determine the shortest removal path based on the concentrated location of the burr features and the preset air path location; The preset magnetic attraction device is controlled with a preset magnetic strength to attract the burr features at the concentrated position of the burr features and is pulled to the air path position according to the shortest removal path.

[0011] Optionally, if the burr feature scratches the contact surface between the movable valve and the static valve, the surface repair method of the gap includes: Acquiring abutment surface image information; Determine the scratch position and scratch path based on the abutment surface image information and preset scratch features; Determine whether the scratch path and the gas channel position coincide with each other; If and only if the scratch path coincides with the gas channel, it is defined as the scratch feature passing through the gas channel, and the filling volume is determined based on the abutment surface image information and the scratch feature; Based on the filling volume being smaller than a preset reference restoration volume, matching the filling volume of the corresponding burr feature according to the filling volume; Determine the melting temperature based on the filling volume, the preset burr material, and the preset material feature library; Select the burr feature to fill the volume and melt the burr feature at the melting temperature before injecting it into the scratch position.

[0012] Optionally, also include: Based on the filling volume being no less than the reference recovery volume, the penetration port position is determined according to the scratch path and the gas path position; Determine the interception point position within the scratch path according to the penetration position, the preset interception distance and the scratch path; Controlling a preset interception device at the interception point position to cut off the scratch path to form an outlet filling slot between the interception point position and the penetration port position; The burr feature is melted at the melting temperature and then injected into the outlet filling groove to cut off the scratch path at the through-mouth position.

[0013] Optionally, the burr feature is collected after being blown out of the air passage by the shock wave. The burr collection method includes: Obtain the weighing weight value of the intermittent motion valve; Determine the burr weight value according to the weighing weight value and the preset reference weight value; Match the adsorption magnetic strength of the magnetic attraction device preset at the outlet of the gas path according to the intensity of the shock wave; The magnetic device is controlled by the adsorption magnetic strength to collect the burr features of the blown air channel. After a preset impact time, the weight of the burrs collected on the magnetic device is obtained. Based on the inconsistency between the burr collection weight and the burr weight value, the shock wave intensity of the high-pressure air release device is increased by a preset enhancement amount, and the adsorption magnetic strength is corrected simultaneously.

[0014] Optionally, the shock wave intensity correction is calculated as: P=P0+μ1*P0*S 总 / (S 道 *ρ*c)+k1*a*P0+k2*μ2*L*P0; Among them, P is the modified shock wave intensity, P0 is the shock wave intensity, μ1 is the energy loss coefficient, S 总 is the total blocking area of ​​all burr features, S 道 is the cross-sectional area of ​​the gas channel, ρ is the air density, c is the propagation speed of the shock wave in the air, k1 is the bending attenuation coefficient, a is the total bending angle, k2 is the channel attenuation coefficient, μ2 is the channel friction coefficient, and L is the total length of the gas channel.

[0015] In a second aspect, the present application provides a manufacturing system for a mechanical intermittent motion valve, which adopts the following technical solution: A manufacturing system for a mechanical intermittent motion valve, comprising: An acquisition module is used to acquire internal gas path images, gap image information, abutment surface image information, weighing weight values, and burr collection weight; A memory for storing a program for the method of manufacturing any one of the mechanical intermittent motion valves; The program in the memory can be loaded and executed by the processor to implement a method for manufacturing a mechanical intermittent motion valve.

[0016] In a third aspect, the present application provides a smart terminal that adopts the following technical solution: An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute any one of the above-mentioned methods for manufacturing a mechanical intermittent motion valve.

[0017] In summary, this application includes at least one of the following beneficial technical effects: A method for manufacturing a mechanical intermittent motion valve includes releasing a shock wave of high-pressure air into an air passage of the motion valve, thereby breaking off burrs in the air passage. After breaking off, the burrs are blown out of the motion valve by airflow, thereby achieving the effect of removing burrs. The above method has a high efficiency in removing burrs in the motion valve. The moving valve is first centrifugally rotated so that the burr features between the moving valve and the static valve can be concentrated together, and then the burr features are adsorbed by a magnetic device to guide the burrs to move along the shortest distance to the air path position, thereby removing the burr features between the moving valve and the static valve. The above method does not require the moving valve to be disassembled for cleaning, and is highly efficient. When scratches and grooves appear on the abutting surface between the dynamic valve and the static valve, the system performs targeted processing based on the volume of the scratch features; if the scratch is small, it is directly repaired by filling the scratch with melted burr features; if the scratch is large, it is repaired by filling and sealing a small area with melted burr features at the connection between the scratch and the air path to improve air tightness. The above method has a high processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The present invention discloses a method for manufacturing a mechanical intermittent motion valve. A high-pressure air release device releases a shock wave into the air passage of the motion valve, thereby breaking off burrs in the air passage. A magnetic device removes burrs that have fallen into the moving and stationary valves, and the burrs are collected. After deburring, scratches caused by the burrs are repaired to ensure airtightness.

[0021] Reference Figure 1 A method for manufacturing a mechanical intermittent motion valve comprises the following steps: Step S100: Acquire an internal gas path image of the intermittent motion valve.

[0022] Internal gas path images refer to images of the gas path within the moving valve of an intermittent motion valve. These images are acquired using a microprobe that is inserted into the gas path, moves along the path, and simultaneously captures the image. If the gas path has burrs, these burrs will appear in the internal gas path image.

[0023] Step S101: Generate an airway channel model based on the internal airway image.

[0024] The airway channel model refers to a spatial three-dimensional model of the airway channel. The distances between each point on the inner wall of the airway channel and the microprobe can be analyzed using image recognition in the internal airway image. Therefore, the airway channel model can be obtained by importing the internal airway image into a pre-set 2D-to-3D image database for processing. This 2D-to-3D image database is a tool database known to those skilled in the art and will not be described in detail here.

[0025] Step S102: Comparing and analyzing the gas path channel model with a preset reference model to determine the burr features and burr feature locations.

[0026] The reference model refers to a reference model of the air passage obtained by technicians through pre-testing a motion valve that has been processed and has no burrs in the air passage. The reference model has no burr features.

[0027] The burr feature position refers to the position of the burr feature in the gas path.

[0028] The air path channel model is compared with the reference model. The difference between the two is the burr feature. After the burr feature is determined, the actual burr feature position of the burr feature in the motion valve can be determined based on the position of the burr feature in the air path channel model.

[0029] Step S103: determining the burr diameter of each burr feature according to the air path model and the burr feature position.

[0030] After determining all the burr features in the air path, the system can analyze each burr specifically and determine the burr diameter corresponding to each burr from the air path model.

[0031] Step S104: comparing each burr feature to determine the burr feature with the largest burr diameter, and determining the maximum burr diameter.

[0032] The maximum burr diameter refers to the diameter of the burr feature with the largest diameter among all burr features. In this embodiment, the maximum burr diameter can be used as a parameter basis for controlling the high-pressure air release device.

[0033] Step S105: matching the shock wave intensity of the preset high-pressure air release device according to the maximum burr diameter.

[0034] Shock wave intensity refers to the impact strength of the gas released by the high-pressure air release device. Shock wave intensity is proportional to the maximum burr diameter; the larger the maximum burr diameter, the greater the shock wave intensity. When the burr feature with the largest burr diameter can be severed by the high-pressure air of the shock wave intensity, other burr features with smaller diameters can also be severed.

[0035] Step S106: controlling the high-pressure air release device to release air shock waves to the air passage of the intermittent motion valve according to the intensity of the shock waves to break the burr features and blow out the intermittent motion valve.

[0036] After the intensity of the shock wave is determined, the high-pressure air release device is controlled to release high-pressure gas to the air passage inlet of the movable valve. When the high-pressure gas passes through the air passage, the burr features in the air passage can be broken and discharged.

[0037] Reference Figure 2 The intensity of the shock wave will be attenuated when it propagates in the air channel. Therefore, it is necessary to correct the intensity of the shock wave of the high-pressure air released by the high-pressure air release device so that the high-pressure air can break all the burr features. The shock wave intensity correction method includes the following steps: Step S200: determining the blocking surface area of ​​each burr feature according to the air path model and the burr features, and determining the total blocking area of ​​all burr features.

[0038] The blocking surface area refers to the area of ​​the projected surface of the burr feature toward the gas channel entrance. The blocking surface area can be directly analyzed by the system from the gas channel model.

[0039] The total blocking area is the sum of the blocking surface areas of all burr features.

[0040] Step S201: determining the influence distance of the burr feature with the largest blocking surface area from the air channel entrance and the distal burr diameter of the burr feature farthest from the air channel entrance according to the air channel model and the burr feature position.

[0041] After determining the blocking surface areas of all burr features, the system can filter out the burr feature with the largest blocking surface area and determine the position of the burr feature in the air path, thereby determining the distance between the burr feature and the air path entrance, which is the impact distance.

[0042] The distal burr diameter refers to the diameter of the burr feature farthest from the gas path. The system can directly determine the burr feature farthest from the gas path from the gas path model, thereby directly obtaining its burr diameter.

[0043] Step S202: determining the regional blocking area of ​​all burr features in the gas path channel affecting the distance according to the affecting distance.

[0044] The regional blocking area refers to the sum of the blocking surface areas of the burr features within the length range of the impact distance in the gas path.

[0045] After determining the impact distance, the system can determine all burr features within the length range of the impact distance according to the gas path channel model, and add up the blocking surface areas of all burr features to obtain the regional blocking area.

[0046] Step S203: determining the regional attenuation of the shock wave according to the regional blocking area, and calculating the sum of the regional attenuation and the shock wave intensity to define it as the regional shock wave intensity.

[0047] When high-pressure gas passes through a gas channel, the burr features block the shock wave, reducing its intensity. The amount of shock wave attenuation caused by the burr features is the regional attenuation. The regional attenuation is the amount of shock wave attenuation after passing through the gas channel at the affected distance. The regional attenuation is proportional to the regional blocking area; the larger the regional blocking area, the greater the regional attenuation.

[0048] Regional shock wave intensity refers to the corrected shock wave intensity, which is the sum of the regional attenuation and the shock wave intensity. When the high-pressure air release device releases a shock wave at regional shock wave intensity, after being blocked by all burr features within the length of the impact distance, the burr feature with the largest burr diameter at the impact distance is broken.

[0049] Step S204: matching the distal shock wave intensity of the burr feature farthest from the gas channel entrance according to the distal burr diameter.

[0050] The distal shock wave intensity refers to the intensity of the shock wave that can break the burr feature farthest from the gas path. The distal shock wave intensity is proportional to the distal burr diameter. The larger the distal burr diameter, the greater the distal shock wave intensity.

[0051] Step S205: determining the far-end attenuation of the shock wave according to the total blocking area, and calculating the sum of the far-end attenuation and the shock wave intensity to define it as the penetrating shock wave intensity.

[0052] The distal attenuation is the attenuation of the shock wave due to obstruction by burrs as it passes through the entire airway. The distal attenuation is related to and proportional to the total obstruction area of ​​all burrs within the airway. The larger the total obstruction area, the greater the distal attenuation.

[0053] Penetrating shock wave intensity refers to the corrected shock wave intensity, which is the sum of the distal attenuation and the shock wave intensity. When the high-pressure air release device releases a shock wave at penetrating shock wave intensity, after passing through all burr features, the burr feature farthest from the air path is broken.

[0054] Step S2061: Based on the regional shock wave intensity being greater than the penetrating shock wave intensity, the regional shock wave intensity is used as a modified shock wave intensity and the modified shock wave intensity is output.

[0055] The regional shock wave intensity is compared with the penetrating shock wave intensity to determine whether the regional shock wave intensity or the penetrating shock wave intensity is used as the final shock wave intensity. The modified shock wave intensity is ultimately used to control the shock wave intensity of the high-pressure air release device. Releasing the shock wave at the modified shock wave intensity can break all burrs in the air path.

[0056] When the regional shock wave intensity is greater than the penetrating shock wave intensity, the shock wave with the penetrating shock wave intensity cannot break the burr feature with the maximum burr diameter at the impact distance. Therefore, the regional shock wave intensity is used as the final corrected shock wave intensity.

[0057] Step S2062: Based on the regional shock wave intensity being no greater than the penetrating shock wave intensity, the penetrating shock wave intensity is used as a corrected shock wave intensity and the corrected shock wave intensity is output.

[0058] When the regional shock wave intensity is not greater than the penetrating shock wave intensity, the shock wave of the regional shock wave intensity cannot break the burr feature farthest from the gas channel entrance, so the penetrating shock wave intensity is used as the final corrected shock wave intensity.

[0059] Reference Figure 3When the shock wave passes through the air channel, it will be blocked by the inner wall and the bend of the air channel, resulting in attenuation. Therefore, the influence of the inner wall and the bend of the air channel needs to be considered. The shock wave intensity correction method also includes the following steps: Step S300: determining the total length of the gas channel according to the gas channel model.

[0060] The total length of the gas path refers to the total length of the gas path in the movable valve. The total length of the gas path can be directly analyzed from the gas path model.

[0061] Step S301: determining the gas path bending characteristics and the total bending angle according to the gas path channel model.

[0062] The gas path bend feature refers to the bend location within the gas path. The total bend angle is the sum of the angles of all bend locations within the gas path. The gas path bend feature can be directly analyzed from the gas path model and its bend angle can be determined. Finally, the total bend angle is calculated by summing the bend angles of all gas path bend features.

[0063] Each time the shock wave passes through a gas path bending feature, it will be weakened to a certain extent, and this is related to the bending angle of the gas path bending feature. Therefore, the total bending angle of all the gas path bending features is determined.

[0064] Step S302: determining the friction attenuation according to the total length of the gas path and a preset channel friction coefficient.

[0065] The channel friction coefficient is a standard parameter obtained by technicians through pre-testing the inner wall of the gas channel, and will not be described in detail here.

[0066] Frictional attenuation is the energy attenuated by the shock wave's friction with the inner wall of the gas channel as it moves through the channel. Frictional attenuation is proportional to the product of the total length of the gas channel and the channel's friction coefficient. The greater the product of the total length and the channel's friction coefficient, the greater the frictional attenuation.

[0067] Step S303: determining the total bending attenuation according to the total bending angle.

[0068] The total bending attenuation is the energy attenuated by the shock wave after passing through all the bending features of the gas path. The total bending attenuation is proportional to the total bending angle. The larger the total bending angle, the greater the total bending attenuation.

[0069] Step S304: determining a final shock wave intensity according to the corrected shock wave intensity, the friction attenuation, and the total bending attenuation.

[0070] The final shock wave intensity is the shock wave intensity obtained by integrating all factors that cause energy attenuation of the shock wave. The final shock wave intensity is the sum of the corrected shock wave intensity, friction attenuation, and total bending attenuation.

[0071] Reference Figure 4 After the burr feature is blown off, it may fall into the gap between the moving valve and the static valve in the intermittent motion valve, causing the gap to widen and leak. The method for handling the burr feature in the gap includes the following steps: Step S400: controlling the intermittent motion valve to rotate at a preset centrifugal speed.

[0072] The centrifugal speed is the rotation speed set by the technicians to drive the intermittent motion valve to rotate circumferentially. When the motion valve rotates at the centrifugal speed, the burrs in the gap can be thrown to the edge and gathered together during the rotation process. I will not go into details here.

[0073] Step S401: After a preset centrifugation time, obtain image information of the gap between the movable valve and the static valve at the connection point of the gas passage.

[0074] The centrifugal time is the time for the intermittent motion valve to rotate set by the technicians, which will not be described in detail here.

[0075] The gap image information is an image obtained by photographing the gap at the connection between the dynamic valve and the static valve in the air passage through a micro probe. The micro probe is in the air passage to photograph the circumferential gap.

[0076] Step S402: determining the gap width between the dynamic valve and the static valve according to the gap image information, and determining the maximum gap width position according to the gap width.

[0077] The gap width refers to the distance between the moving and static valves at the gas path connection. This gap width can be determined from gap image information using image recognition. When burrs are present between the moving and static valves, the burrs stretch them apart, making the gap width between them uneven along the circumference. Therefore, once the circumferential gap width between the moving and static valves is determined, the gap width can be analyzed and identified, thereby determining the location of the maximum gap width.

[0078] Step S403: determining the burr feature concentration position according to the maximum gap width position.

[0079] The burr feature concentration position refers to the position between the moving valve and the static valve after the burr feature is centrifugally concentrated.

[0080] The reason for the maximum gap width position is that there is a burr feature on the extension line of the line connecting the maximum gap width position and the center of the air path channel. Therefore, the maximum gap width position is raised. According to the above principle, the burr feature concentration position can be determined by the maximum gap width position.

[0081] Step S404: determining the shortest removal path according to the concentrated location of the burr features and the preset gas path location.

[0082] The position of the air passage refers to the position of the air passage at the connection between the moving valve and the static valve in the moving valve, which will not be described here.

[0083] The shortest removal path refers to the shortest distance path taken to move the burr feature from the burr feature concentration location to the air path location. The shortest removal path is the line connecting the burr feature concentration location and the air path location.

[0084] Step S405: controlling a preset magnetic attraction device with a preset magnetic strength to attract the burr features at the burr feature concentration location and pulling them to the air passage location along the shortest removal path.

[0085] Directly removing the burr feature from the movable valve and the static valve is not easy to operate and cannot be handled cleanly. In this embodiment, since the burr feature is made of ferrous metal material, a magnetic attraction device is provided around the movable valve to generate a magnetic field that can attract the burr feature, thereby guiding the movement of the burr feature and pulling the burr feature to the air path position along the shortest removal path.

[0086] The magnetic strength is the strength of the magnetic force after the magnetic device set by the technician pulls the burr feature. When the magnetic field is the magnetic strength, it can attract the burr feature, which will not be elaborated here.

[0087] Reference Figure 5 The burr feature scratches the contact surface between the dynamic valve and the static valve. The surface repair method of the gap includes the following steps: Step S500: Acquire abutment surface image information.

[0088] The abutment surface image information is an image of the abutment surface between the dynamic and static valves captured by a camera. After the burr features are removed and the moving valve is tested, if air leakage is detected, the dynamic and static valves are disassembled and image recognition of the abutment surface between them is performed again.

[0089] Step S501: determining the scratch position and scratch path according to the abutting surface image information and preset scratch features.

[0090] The scratch position refers to the location of the scratch feature on the contact surface between the movable and stationary valves, and the scratch path refers to the shape trajectory of the scratch feature. The scratch position and scratch path can be determined by performing image recognition analysis on the scratch features in the contact surface image information.

[0091] Step S502: Determine whether the scratch path and the air channel position overlap based on the scratch path and the air channel position.

[0092] By determining whether the scratch path and the air passage overlap, it can be determined whether the scratch feature penetrates the air passage. If so, premature air leakage will occur if the air passages of the movable and static valves are disconnected. If not, there will be no impact. The treatment method is determined based on whether the two overlap.

[0093] Step S503: If and only if the scratch path coincides with the air passage, it is defined as the scratch feature passing through the air passage, and the filling volume is determined based on the abutment surface image information and the scratch feature.

[0094] Repair is required when the scratch path coincides with the air passageway, meaning the scratch extends through the air passageway. The fill volume refers to the volume of the indentation caused by the scratch feature on the abutment surface between the movable and stationary valves. This fill volume can be determined by performing image recognition analysis on the scratch feature from the abutment surface image information.

[0095] Step S504 : Based on the filling volume being smaller than the preset reference restoration volume, a filling volume of the corresponding burr feature is matched according to the filling volume.

[0096] By analyzing the size of the filling volume, different repair methods are used for scratch characteristics with different filling volumes.

[0097] The reference restoration volume is a parameter set by technicians to measure whether the scratch feature needs to be completely filled and repaired, and will not be described in detail here.

[0098] When the filling volume is not less than the reference restoration volume, it means that the scratch feature is large and it does not need to be completely filled and repaired. The specific repair method will not be described here and will be introduced in detail in subsequent embodiments.

[0099] When the filling volume is smaller than the baseline restoration volume, it means that the scratch feature is small. In this case, the scratch feature can be directly filled and repaired.

[0100] In this embodiment, the burr features that were broken off within the gas path are recovered and melted to repair the scratch features. The fill volume refers to the volume of the burr feature used to repair the scratch feature. The fill volume corresponds one-to-one with the filling volume.

[0101] Step S505 : determining a melting temperature according to the filling volume, the preset burr material, and the preset material feature library.

[0102] The melting temperature is the temperature required to melt the burr feature. By entering the fill volume and burr material into the material feature library, the melting temperature required to melt the burr corresponding to the fill volume can be matched. The material feature library is a standard database set by technicians, which contains the corresponding relationship between fill volume, burr material and melting temperature.

[0103] Step S506: Select the burr feature of the filling volume and melt the burr feature at the melting temperature and then inject it into the scratch position.

[0104] After determining the melting temperature, the system selects the appropriate burr features and melts them through the melting temperature, and finally injects them into the scratch position.

[0105] Reference Figure 6 , the gap surface repair method also includes the following steps: Step S600: Based on the fact that the filling volume is not less than the reference restoration volume, the position of the through-hole is determined according to the scratch path and the position of the gas channel.

[0106] When the filling volume is not less than the baseline recovery volume, the scratch feature does not need to be completely filled and repaired due to its large size. In this embodiment, repair is performed at the junction of the scratch feature and the air passage. The through-hole location refers to the junction between the scratch feature and the air passage, which is located at the edge of the air passage. Analyzing the scratch path and the air passage location, the point where the two overlap is the through-hole location.

[0107] Step S601: determining the interception point position within the scratch path according to the penetration position, the preset interception distance and the scratch path.

[0108] The interception distance is the distance set by technicians to allow the melted burr features to flow through and be filled. It is also a reference for setting the interception device and will not be elaborated here.

[0109] The interception point position is the position where an interception device is set on the scratch path to prevent the melted burr feature from flowing through. The interception point position can be determined based on the penetration position and the interception distance. The position when moving the interception distance along the scratch path from the penetration position is the interception point position.

[0110] Step S602: Controlling a preset interception device at the interception point position to cut off the scratch path to form an outlet filling slot between the interception point position and the penetration port position.

[0111] When an interception device is set at the interception point position, an outlet filling groove will be formed between the interception point position and the through-port position. By injecting the melted burr feature into the outlet filling groove, the connection between the scratch feature and the air path position can be switched, so that when air enters the scratch feature, it will not leak out from the through-port position.

[0112] Step S603: melting the burr feature at a melting temperature and then injecting the outlet filling groove to cut off the scratch path at the through-opening position.

[0113] Similar to step S506, the burr feature is melted and then injected into the outlet filling groove. At this time, when the melted burr feature cools and hardens, it can block the connection between the scratch feature and the gas path position.

[0114] Reference Figure 7 The burr features are blown out of the air passage by the shock wave and then collected. The burr collection method includes the following steps: Step S700: Obtain the weighing weight value of the intermittent motion valve.

[0115] The weighing weight value is the weight obtained by weighing the intermittent motion valve using a weighing device before the burr features are removed.

[0116] Step S701: determining a burr weight value according to a weighing weight value and a preset reference weight value.

[0117] The reference weight value is the standard weight parameter of the intermittent motion valve. The weight measured at this time is the motion valve without any burr features inside.

[0118] The burr weight value refers to the weight of the burr feature in the motion valve to be tested. The weighing weight value can be determined by calculating the difference between the weighing weight value and the reference weight value.

[0119] Step S702: Matching the adsorption magnetic strength of the magnetic attraction device preset at the outlet of the gas channel according to the shock wave strength.

[0120] In this embodiment, a magnetic attraction device is provided at the outlet of the air passage, so that the magnetic attraction device can attract the burr features of the blown motion valve and collect them.

[0121] The adsorption magnetic strength is the magnetic strength provided by the magnetic device when adsorbing the burr feature. The adsorption magnetic strength is proportional to the shock wave strength. The greater the shock wave strength, the greater the adsorption magnetic strength. As a result, the burr feature can be adsorbed by the magnetic device when it is flushed out of the motion valve by the shock wave and is not easily blown away.

[0122] Step S703: controlling the magnetic device to collect burr features of the blown air passage by using the adsorption magnetic strength, and obtaining the burr collection weight on the magnetic device after a preset impact time.

[0123] The impact time is the time set by the technicians for the shock wave to impact the burr feature to remove the burr, which will not be described in detail here.

[0124] The burr collection weight refers to the weight of the burr feature collected by the magnetic device after the burr feature is flushed out of the motion valve by the shock wave. The magnetic device is provided with a pressure sensor, and the burr collection weight can be measured by the pressure sensor.

[0125] Step S704: Based on the inconsistency between the burr collection weight and the burr weight value, the shock wave intensity of the high-pressure air release device is increased by a preset enhancement amount, and the adsorption magnetic strength is corrected simultaneously.

[0126] When the burr collection weight matches the burr weight value, the burrs within the valve have been removed and collected by the magnetic device. If the burr collection weight does not match the burr weight value, it indicates that burr features remain within the valve, possibly indicating insufficient shock wave intensity. In this case, the shock wave intensity should be increased. The enhancement amount is the amount set by the technician to correct for insufficient shock wave intensity and is not detailed here.

[0127] The calculation formula for shock wave intensity correction is: P=P0+μ1*P0*S 总 / (S 道 *ρ*c)+k1*a*P0+k2*μ2*L*P0; Among them, P is the modified shock wave intensity, P0 is the shock wave intensity, μ1 is the energy loss coefficient, S 总 is the total blocking area of ​​all burr features, S 道 is the cross-sectional area of ​​the gas channel, ρ is the air density, c is the propagation speed of the shock wave in the air, k1 is the bending attenuation coefficient, a is the total bending angle, k2 is the channel attenuation coefficient, μ2 is the channel friction coefficient, and L is the total length of the gas channel.

[0128] Three factors contribute to shock wave attenuation: The first is burrs in the air path, which block the shock wave. The second is bends in the air path, which hinder the shock wave. The third is friction between the shock wave and the inner wall of the air path, which attenuates the shock wave. These three factors must be considered when correcting the shock wave intensity, and the attenuation is added to the initial shock wave intensity.
