[0001] The present invention relates to the technical field of cams, and in particular to a cam-based production detection method, system and cam. Background Art

[0002] A dog is a mechanical connection part used on the motor shaft and the connecting shaft.

[0003] The claws are evenly provided with protrusions, which are used to mesh with the grooves or structures on the connecting shaft to transmit the torque of the motor shaft to the connecting shaft. During the production inspection of the claws, the blank is processed by a manually operated machine tool with a preset size to obtain the claws.

[0004] During the production inspection of the claws, manual machine operation may result in operating errors, which may cause deviations in the size of the claws. Summary of the invention

[0005] In order to improve the accuracy of production detection of claws, the present invention provides a production detection method and system based on claws and claws.

[0006] In a first aspect, the present invention provides a production detection method based on a protruding claw, which adopts the following technical solution: A production detection method based on a cam, comprising: Collecting manufacturing parameters of the claws; Responding to manufacturing parameters and preset blank specifications to generate a cutting path, and inputting it into a preset cutting device for cutting; When the cutting device completes cutting, the manufacturing parameters are matched to the estimated burr range, and the preset cutting wire is controlled to run within the estimated burr range to generate a burr path; Obtaining a burr segmentation point based on manufacturing parameters and a burr path, and controlling the cutting wire to cut the burr at the burr segmentation point; A grinding path is obtained in response to the burr path and the burr dividing point, and a preset grinding device is controlled to run along the grinding path.

[0007] By adopting the above technical scheme, the manufacturing parameters of the claws are analyzed to obtain the cutting path and the estimated range of the burrs, and the cutting device is controlled to cut along the cutting path. The burr segmentation points and the grinding path are generated by the cutting wire and the manufacturing parameters, and the grinding device and the cutting wire are controlled to operate according to the burr segmentation points and the grinding path. Thus, the claws can be automatically cut and produced to improve the accuracy of the claw production detection, and the burrs on the claws can be removed. While removing the burrs, the position offset of the burrs caused by the grinding device can be reduced, thereby improving the accuracy of the burr removal.

[0008] Optionally, the method after the grinding device runs in the grinding path includes: The center position of the claw is retrieved from the manufacturing parameters, and the claw is clamped to a preset weight detection position; When the center position of the convex claw coincides with the weight detection position, controlling the preset cutting wire to wind the convex claw with a preset number of winding turns; The friction coefficient of the cam is retrieved from the manufacturing parameters; Responding to the friction coefficient of the pawl and the preset friction coefficient of the wire to match the tightening force; Collect and output the pulling force of the wire reel with the cutting wire; From the traction forces, a traction force greater than the tightening force is retrieved as the marking force; The difference between the marked force and the tightening force is calculated as the force deviation value; A weight deviation parameter is matched in response to the force deviation value, and the cutting path is updated by the weight deviation parameter.

[0009] By adopting the above technical solution, the cutting wire is controlled to wrap around the claw so that the claw is suspended in the air, and then the force deviation value is calculated by marking the force and the tightening force, and the weight deviation parameter is obtained by the force deviation value to update the cutting path, so as to know the parameter deviation of the automatic processing of the claw to facilitate the subsequent processing of the claw.

[0010] Optionally, the method after the grinding device runs along the grinding path further comprises: Clamp the claw to a preset size detection position; When the center position of the claw coincides with the size detection position, responding to the manufacturing parameters to obtain the compacted volume of the plasticine; Placing a compacted volume of plasticine at the center of the claws, and controlling a preset squeezing device to compact the plasticine at a preset compacting speed; Collecting the pressure detection value on the extrusion device and updating the pressure detection value at a preset unit time; Calculate the difference between the pressure detection values ​​before and after the update as the pressure change value; When the pressure change value is greater than the preset reference change value, the gap change value is matched by manufacturing parameters; When the pressure change value and the gap change value are inconsistent, the cutting path is updated according to the pressure change value and the gap change value.

[0011] By adopting the above technical solution, the plasticine is compressed to fill the protruding claws by controlling the extrusion device, and the pressure change value is obtained by the pressure detection value on the extrusion device. A new cutting path is obtained based on the comparison between the pressure change value and the reference change value, so that the size deviation of the protruding claws can be known by knowing the diffusion of the plasticine.

[0012] Optionally, the method for updating the cutting path according to the pressure change value and the gap change value includes: Update the pressure change value per unit time; Responding to the pressure change value before and after the update to match the detection angle value; When the detected angle value is consistent with the preset reference angle value, the cutting path is updated through the updated pressure change value; When the detected angle value is inconsistent with the preset reference angle value, the difference between the detected angle value and the reference angle value is calculated as the angle deviation value; The cutting path is updated according to the updated pressure change value and angle deviation value.

[0013] By adopting the above technical solution, the cutting path is updated according to the pressure change value and the angle deviation value by comparing the detected angle value with the reference angle value, so as to further know the parameter deviation of the claw and improve the accuracy of the cutting path adjustment.

[0014] Optionally, also include: When the detected angle value is inconsistent with the preset reference angle value, other pressure values ​​on the extrusion device are collected and updated per unit time; Calculate the difference between other pressure values ​​before and after the update as other change value; When the other change value is greater than the gap change value, responding to the other change value to match the detection offset distance; Responding to the pressure change value to match the reference offset distance; Update the cutting path based on the detection offset distance and the base offset distance.

[0015] By adopting the above technical solution, when the detected angle value is consistent with the reference angle value, other change values ​​are obtained through other pressure values, and the detected offset distance and the reference offset distance are obtained based on the comparison between the other change values ​​and the gap change value. The new cutting path is obtained by detecting the offset distance and the reference offset distance, so that it can be known that the position of the protruding part of the claw is offset, thereby improving the accuracy of the cutting path adjustment.

[0016] Optionally, the method after obtaining the compacted volume of the plasticine in response to the manufacturing parameters comprises: Retrieving the reference expansion range from the manufacturing parameters; Responding to the friction coefficient of the claw, the preset extrusion friction coefficient and the extrusion speed to match the expansion range; The detection height of the plasticine is obtained through the expansion range, the compacted volume and the reference expansion range; When the detection height exceeds the preset reference height, the detection range is generated according to the reference height and the compaction volume; obtaining a deviation range in response to the expansion range, the detection range, and the reference expansion range; Match the buffer strength according to the deviation range; The inflation amount is matched by the buffering force, and the airbag device preset on the extrusion device is controlled to output the inflation amount so as to extrude the plasticine through the airbag device.

[0017] By adopting the above technical solution, when the plasticine is squeezed by the squeezing device, the airbag device is controlled to inflate with an inflation amount by analyzing the expansion of the plasticine, thereby slowing down the expansion range of the plasticine and reducing the probability of the plasticine expanding to the protruding part.

[0018] Optionally, the method of squeezing the plasticine by the air bag device includes: When the pressure detection value is consistent with the preset extrusion force, the moving distance of the extrusion device is collected; When the moving distance is inconsistent with the reference height, the difference between the moving distance and the reference height is calculated as the height deviation value; Update the cutting path according to the height deviation value; When the moving distance is consistent with the reference height, re-collect other pressure values; When the other pressure values ​​are less than the squeezing force, the squeezing device is controlled to continue to descend to obtain the inflation supplement distance until the other pressure values ​​are consistent with the squeezing force, and the supplementary movement distance is collected; Responding to the compaction volume, the base height, and the travel distance to match the diffusion fatigue of the plasticine; Generate the minimum diffusion thickness according to the diffusion fatigue and extrusion strength; The height reduction parameter is obtained by supplementing the moving distance, diffusing the minimum thickness and inflating the supplement distance, and the cutting path is updated according to the height reduction parameter.

[0019] By adopting the above technical solution, the cutting path is updated or other pressure values ​​are obtained by obtaining the height deviation value based on the consistency between the moving distance and the reference height, and the cutting path is updated by obtaining the height reduction parameter based on the consistency between other pressure values ​​and the extrusion force. This allows the height value of the protruding part to be reduced when the diffusion of the plasticine is reduced, thereby improving the accuracy of the cutting path adjustment.

[0020] Optionally, the method of controlling the extrusion device to continue to descend includes: Retrieving the protruding area of ​​the claw from the manufacturing parameters; Responding to other pressure values, pressure detection values, and squeeze strength to obtain a deviation amount; Responsive to the protrusion area and the deviation amount to obtain a total contact area; Responding to the inflation amount and a preset reference inflation amount to obtain an inflation replenishment distance; The product of the inflation replenishment distance and the total contact area is calculated to obtain the total contact volume, and the total contact volume is updated according to the preset unit moving distance; Obtaining a marked inflation volume according to the updated total contact volume and the reference inflation volume; The difference between the inflation amount and the marked inflation amount is calculated and used as the supplementary inflation amount, and when the squeezing device continues to descend, the airbag device is inflated and deflated with the supplementary inflation amount.

[0021] By adopting the above technical solution, the situation of the protruding part sinking into the airbag is analyzed to obtain the supplementary inflation amount, and the airbag device is inflated. As a result, when the extrusion device continues to descend and the protruding part of the claw sinks into the airbag, the airbag that is not in contact with the protruding part can maintain a certain air pressure value, so as to facilitate the continued detection of the height deviation of the protruding part.

[0022] In a second aspect, the present application provides a production detection system based on a cam, which adopts the following technical solution: A production detection system based on a cam, comprising: An acquisition module, used for acquiring manufacturing parameters; A memory for storing a production detection method based on a cam; The processor is used to load, execute and implement the program stored in the memory.

[0023] In a third aspect, a claw is applied to the above-mentioned claw-based production detection method, comprising a body, protruding parts evenly arranged on the body, and a tooth groove opened in the center of the body.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Analyze the manufacturing parameters of the claws to control the cutting device to cut along the cutting path, and then control the grinding device and the cutting wire by the burr segmentation point and the grinding path, so that the claws can be automatically cut and produced to improve the accuracy of the claw production detection, and the burrs on the claws can be removed. While removing the burrs, the position offset of the burrs caused by the grinding device can be reduced, thereby improving the accuracy of burr removal; 2. When the plasticine is squeezed by the squeezing device, the airbag device is controlled to inflate with an inflation amount by analyzing the expansion of the plasticine, thereby slowing down the expansion range of the plasticine and reducing the probability of the plasticine expanding to the protruding part; 3.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Reference Figure 1 The embodiment of the present application discloses a claw, including a body 1, protruding parts 2 evenly arranged on the body 1, and tooth grooves 3 opened on the body 1, four protruding parts 2 are arranged on the body 1, the tooth grooves 3 penetrate the body 1 and are coaxial with the body 1.

[0029] Reference Figure 2The present application embodiment discloses a production detection method based on a protruding claw, comprising the following steps: Step S100: collecting manufacturing parameters of the claws.

[0030] The manufacturing parameters refer to parameters such as the size of the claws and the friction coefficient, which can be obtained through pre-input by the operator.

[0031] Step S101: generating a cutting path in response to manufacturing parameters and preset blank specifications, and inputting the path into a preset cutting device for cutting.

[0032] The cutting device refers to a machine tool used to cut a blank. Blank specifications are the size specifications of the blank used to make the claws set by the technician. The cutting path refers to the path from the blank to the claws. The cutting path is obtained by analyzing the manufacturing parameters and the blank specifications, and the cutting device is controlled to cut the blank along the cutting path. The analysis method of the cutting path is common knowledge known to those skilled in the art and will not be described in detail here.

[0033] Step S102: When the cutting device completes cutting, the manufacturing parameters are matched to the burr estimation range, and the preset cutting wire is controlled to run within the burr estimation range to generate a burr path.

[0034] The burr estimation range refers to the range where burrs are likely to appear on the claws. The burr estimation range is matched from a preset burr database through manufacturing parameters. The burr estimation range corresponding to different manufacturing parameters is stored in the burr database. The parameters in the burr database are set by technicians in this field in advance according to actual conditions, and will not be described in detail here.

[0035] The cutting wire is a wire used to remove burrs. The wire is generated by a wire reel, and a traction sensor for detecting the traction force of the wire is provided on the wire reel. The burr path refers to the path where the burrs appear on the claws. The burr path is drawn by the cutting wire in the burr estimation range. When the traction force changes, it means that the burrs actually appear in the burr estimation range, and the burr path is recorded and drawn. The drawn path is the burr path.

[0036] Step S103: obtaining a burr segmentation point based on the manufacturing parameters and the burr path, and controlling the cutting wire to cut the burr at the burr segmentation point.

[0037] The burr dividing point refers to the position point used to divide the burr path. The point where the straight line formed by the side of the protruding part 2 and the center of the claw intersects the burr path is used as the burr dividing point, and the cutting wire is controlled to cut the burr at the burr dividing point.

[0038] Step S104: obtaining a grinding path in response to the burr path and the burr segmentation point, and controlling a preset grinding device to run along the grinding path.

[0039] The grinding device is a device provided with a micro grinding head. The grinding path refers to the path for grinding the burrs, and the burr path divided by the burr dividing point is used as the grinding path and input into the preset grinding device to run the grinding path.

[0040] Reference Figure 3 , the method after the grinding device is operated in the grinding path includes: Step S200: Retrieve the center position of the claw from the manufacturing parameters, and clamp the claw to a preset weight detection position.

[0041] The center position of the claw refers to the center position of the claw, which is obtained by calling the center position of the claw from the manufacturing parameters. The weight detection position is the position set by the technician to detect the weight distribution of the claw. The clamping device is a mechanical claw, and the claw is clamped to the weight detection position by the clamping device.

[0042] Step S201: When the center position of the claw coincides with the weight detection position, the preset cutting wire is controlled to wind around the claw with a preset number of winding turns.

[0043] The number of winding turns is the number of turns set by the technician for winding the claw. When the center position of the claw coincides with the weight detection position, it means that the claw is at the weight detection position, and the cutting wire is controlled to wind the claw with the number of winding turns. In this embodiment, there are two wire drums for winding the claw. When the wire drums are wound, the protruding parts 2 are evenly distributed on both sides of the wire drum to facilitate the weight distribution detection of the claw.

[0044] Step S202: Retrieve the friction coefficient of the claw from the manufacturing parameters.

[0045] The cam friction coefficient refers to the friction coefficient of the cam, and the cam friction coefficient is obtained from the manufacturing parameters.

[0046] Step S203: matching the tightening force in response to the friction coefficient of the pawl and the preset friction coefficient of the wire.

[0047] The wire friction coefficient is the friction coefficient of the cutting wire set by the technician. The tightening force refers to the force required to cut the wire to make the claws suspended in the air. The tightening force is matched by inputting the claw friction coefficient and the wire friction coefficient into the preset tightening database. The tightening database stores the tightening forces corresponding to different claw friction coefficients and wire friction coefficients. The parameters in the tightening database are set by technicians in this field in advance according to actual conditions, and will not be elaborated here.

[0048] Step S204: collecting and outputting the pulling force of the wire reel having the cutting wire.

[0049] The pulling force refers to the pulling force of the cutting wire, which is collected from the pulling sensor on the wire drum.

[0050] Step S205: Retrieving a traction force greater than the tightening force from the traction forces as a marking force.

[0051] The marking force refers to a traction force greater than the tightening force, and the traction force greater than the tightening force is retrieved from the traction force as the marking force.

[0052] Step S206: Calculate the difference between the marking force and the tightening force as the force deviation value.

[0053] The force deviation value refers to the deviation value between the marked force and the tightening force. The difference between the marked force and the tightening force is calculated as the force deviation value.

[0054] Step S207: matching a weight deviation parameter in response to the force deviation value, and updating the cutting path by the weight deviation parameter.

[0055] The weight deviation parameter refers to the parameter of the weight deviation on the claw. The weight deviation parameter is matched from the preset deviation database through the force deviation value, and the cutting path is regenerated through the weight deviation parameter. The method of regenerating the cutting path is common knowledge to those skilled in the art and will not be elaborated here.

[0056] The deviation database stores weight deviation parameters corresponding to different force deviation values. The parameters in the deviation database are set by technicians in this field in advance according to actual conditions and will not be described in detail here.

[0057] Reference Figure 4 , the method after the grinding device runs along the grinding path further comprises: Step S300: clamping the claws to a preset size detection position.

[0058] The size detection position is a position set by a technician to detect whether the claw has a size deviation. The claw is clamped to the size detection position by a clamping device.

[0059] Step S301: When the center position of the claw coincides with the size detection position, the compacted volume of the plasticine is obtained in response to the manufacturing parameters.

[0060] The compacted volume refers to the volume of the plasticine used to detect the size of the claw. When the center position of the claw coincides with the size detection position, it means that the claw moves to the size detection position. The compacted volume is obtained by analyzing the size in the manufacturing parameters. In this embodiment, the claw is a cylinder, and the plasticine is used to supplement the claw including the protrusion 2 and the tooth groove 3 into a complete cylinder.

[0061] Step S302: placing a compacted volume of plasticine at the center of the claws, and controlling a preset squeezing device to compact the plasticine at a preset compacting speed.

[0062] The squeezing device includes a cylinder, a disc with the same area as the bottom surface of the claw, and a telescopic rod arranged between the cylinder and the disc. The pressing speed is the speed at which the squeezing device presses the plasticine set by the technician. The squeezing device is controlled to press the plasticine at the pressing speed. In this embodiment, when the claw is squeezed, a cylindrical through groove is provided at the size detection position for sleeved on the claw to reduce the probability of the plasticine expanding outside the claw, and the plasticine is located on the side of the claw where the protruding portion 2 is provided.

[0063] Step S303: collecting the pressure detection value on the extrusion device, and updating the pressure detection value at a preset unit time.

[0064] The unit time is the time length value set by the technician to update the pressure value. The pressure detection value refers to the pressure value on the extrusion device. When the extrusion device compresses the plasticine, the pressure value retrieved from the pressure sensor array set on the extrusion device is used as the pressure detection value, and the pressure detection value is updated by the unit time.

[0065] Step S304: Calculate the difference between the pressure detection values ​​before and after the update as the pressure change value.

[0066] The pressure change value refers to the change in pressure when the squeezing device compresses the plasticine, and the pressure change value is obtained by calculating the difference between the pressure detection values ​​before and after the update.

[0067] Step S305: When the pressure change value is greater than a preset reference change value, the clearance change value is matched by manufacturing parameters.

[0068] The reference change value is the maximum value of the pressure on the extrusion device before the plasticine diffuses to the protrusion 2, which is set by the technician. The gap change value refers to the pressure value on the extrusion device when the plasticine diffuses to the protrusion 2. When the pressure change value is greater than the reference change value, it means that the plasticine diffuses to the protrusion 2, and the manufacturing parameters are input into the preset gap database to match the gap change value. The gap database stores the gap change values ​​corresponding to different manufacturing parameters. The parameters in the gap database are set by technicians in this field in advance according to actual conditions, and will not be elaborated here.

[0069] Step S306: When the pressure change value and the gap change value are inconsistent, updating the cutting path according to the pressure change value and the gap change value.

[0070] When the pressure change value is inconsistent with the gap change value, it indicates that there is a size deviation in the gap between the protruding parts 2, and a new cutting path is obtained by analyzing the pressure change value and the gap change value.

[0071] Reference Figure 5 The method for updating the cutting path according to the pressure change value and the gap change value includes: Step S400: updating the pressure change value per unit time.

[0072] Step S303 and step S304 are re-executed in unit time.

[0073] Step S401: responding to the pressure change values ​​before and after the update to match the detection angle value.

[0074] The detection angle value refers to the angle value between the side of the protruding portion 2 and the center of the claw, and the detection angle value is matched by inputting the pressure change value before and after the update into the preset angle database. The angle database stores the detection angle values ​​corresponding to different pressure change values ​​before and after the update. The parameters in the angle database are set by the technicians in this field in advance according to the actual situation, and will not be described in detail here.

[0075] Step S402: When the detected angle value is consistent with the preset reference angle value, the cutting path is updated by using the updated pressure change value.

[0076] The reference angle value is the angle value set by the technician at which no dimensional deviation occurs on the side of the protruding part 2. When the detected angle value is consistent with the reference angle value, it indicates that there is a dimensional deviation of the protruding part 2. Then, the deviation dimension is matched from the preset dimension database through the updated pressure change value, and the cutting path is regenerated through the deviation dimension. The dimension database stores the deviation dimensions of the protruding part 2 corresponding to different pressure change values. The parameters in the dimension database are set by the technicians in the field in advance according to the actual situation, and will not be elaborated here.

[0077] Step S403: When the detected angle value is inconsistent with the preset reference angle value, the difference between the detected angle value and the reference angle value is calculated as the angle deviation value.

[0078] The angle deviation value refers to the deviation value between the detected angle value and the reference angle value. When the detected angle value is inconsistent with the reference angle value, it means that there is a center position offset or size deviation in the protruding part 2. The difference between the detected angle value and the reference angle value is calculated as the angle deviation value.

[0079] Step S404: updating the cutting path according to the updated pressure change value and angle deviation value.

[0080] Refer to step S402 to obtain the deviation size, and regenerate the cutting path according to the deviation size and the angle deviation value.

[0081] Reference Figure 6 The method for updating the cutting path according to the pressure change value and the gap change value also includes: Step S500: When the detected angle value is inconsistent with the preset reference angle value, other pressure values ​​on the extrusion device are collected and updated per unit time.

[0082] Other pressure values ​​refer to pressure values ​​detected by other pressure sensors on the extrusion device. The pressure values ​​detected by other pressure sensors on the array of the extrusion device are used as other pressure values, and the other pressure values ​​are updated per unit time.

[0083] Step S501: Calculate the difference between other pressure values ​​before and after the update as other change values.

[0084] Other change values ​​refer to change values ​​of other pressure values ​​on the extrusion device, and the difference between other pressure values ​​before and after the update is calculated as the other change value.

[0085] Step S502: When the other change value is greater than the gap change value, respond to the other change value to match the detection offset distance.

[0086] The detection offset distance refers to the distance at which the center position of the protruding part 2 of other change values ​​is offset. When the other change value is greater than the gap change value, it means that there is a size offset or position offset in other protruding parts. The detection offset distance is matched from the preset offset database through the other change values. The offset database stores the offset distances of the protruding part 2 corresponding to different pressure change values. The parameters in the offset database are set in advance by technicians in this field according to actual conditions, and will not be elaborated here.

[0087] Step S503: responding to the pressure change value to match a reference offset distance.

[0088] The reference offset distance refers to the distance at which the center position of the protruding portion 2 of the pressure change value is offset. Referring to step S502 , the reference offset distance is matched from the offset database using the pressure change value.

[0089] Step S504: updating the cutting path according to the detected offset distance and the reference offset distance.

[0090] When the detected offset distance is consistent with the reference offset distance, it means that only the position point of the protruding part 2 is offset, and the cutting path is regenerated by detecting the offset distance. When the detected offset distance is inconsistent with the reference offset distance, it means that the protruding part 2 has a size offset, and the cutting path is regenerated by detecting the offset distance and the reference offset distance.

[0091] Reference Figure 7 , the method after obtaining the compacted volume of the plasticine in response to the manufacturing parameters comprises: Step S600: Retrieve a reference expansion range from manufacturing parameters.

[0092] The reference expansion range refers to the range in which the plasticine near the extrusion device can expand, and the range surrounded by the side of the protruding portion 2 close to the tooth groove 3 is retrieved from the manufacturing parameters as the reference expansion range.

[0093] Step S601: responding to the friction coefficient of the claw, the preset extrusion friction coefficient and the extrusion speed to match the expansion range.

[0094] The extrusion friction coefficient is the friction coefficient of the disc on the extrusion device set by the technician. The expansion range refers to the range in which the plasticine near the extrusion device expands. The expansion range is matched from a preset expansion database through the cam friction coefficient, the extrusion friction coefficient and the extrusion speed. The expansion database stores the expansion ranges corresponding to different cam friction coefficients, extrusion friction coefficients and extrusion speeds. The faster the extrusion speed, the larger the expansion range. The parameters in the expansion database are set by the technicians in this field in advance according to the actual situation, and will not be described here. In this embodiment, the plasticine is a cylinder when it is not compacted.

[0095] Step S602: Obtain the detection height of the plasticine through the expansion range, the compaction volume and the reference expansion range.

[0096] The detection height refers to the height of the plasticine. The difference between the baseline expansion range and the expansion range is calculated as the detection expansion range. The height of the plasticine is obtained by analyzing the compacted volume and the detection expansion range as the detection height. The analysis method of the detection height is common knowledge among technicians in this field and will not be elaborated here.

[0097] Step S603: When the detection height exceeds the preset reference height, a detection range is generated according to the reference height and the compaction volume.

[0098] The reference height is the maximum height of the plasticine squeezed by the squeezing device set by the technician. When the detection height exceeds the reference height, it means that the plasticine is not easily squeezed by the squeezing device. Then, the reference height and the squeezed volume are analyzed to obtain the detection range. The analysis method of the detection range is common knowledge among technicians in this field and will not be elaborated here.

[0099] Step S604: Obtaining a deviation range in response to the expansion range, the detection range, and the reference expansion range.

[0100] The deviation range refers to the range in which the plasticine will expand to the protruding portion 2 when squeezed. The sum of the expansion range and the detection range is calculated as the total expansion range, and the difference between the total expansion range and the reference expansion range is calculated as the deviation range.

[0101] Step S605: Matching the buffering force according to the deviation range.

[0102] The buffering force refers to the force required to buffer the plasticine, and the buffering force is matched from a preset buffering database through the deviation range. The buffering database stores the buffering forces corresponding to different deviation ranges. The parameters in the buffering database are set by technicians in this field in advance according to actual conditions, and will not be described in detail here.

[0103] Step S606: Matching the inflation amount through the buffering force, and controlling the airbag device preset on the squeezing device to output the inflation amount to squeeze the plasticine through the airbag device.

[0104] The airbag device includes an airbag and an extrusion disc disposed between the airbag and the pressure sensor on the extrusion device. The inflation amount refers to the volume of gas required to inflate the airbag device on the extrusion device. The inflation amount is matched from a preset inflation database through the buffering force, and the airbag device is controlled to output the inflation amount to extrude the plasticine through the airbag device. In this embodiment, when the airbag device is inflated, the airbag will generate pressure on the pressure sensor. When the airbag device is completely inflated, the pressure sensor is reset to 0, and the distance required to move the extrusion device is updated.

[0105] The inflation database stores inflation volumes corresponding to different buffering forces. The parameters in the inflation database are set by technicians in this field in advance according to actual conditions, and will not be described in detail here.

[0106] Reference Figure 8 , the method of squeezing the plasticine by the air bag device includes: Step S700: When the pressure detection value is consistent with the preset squeezing force, the moving distance of the squeezing device is collected.

[0107] The squeezing force is the force set by the technicians to squeeze the plasticine by the squeezing device. When the pressure detection value is consistent with the squeezing force, it means that the plasticine has been squeezed, and the parameter detected by the displacement sensor in the squeezing device is used as the moving distance.

[0108] Step S701: When the moving distance is inconsistent with the reference height, the difference between the moving distance and the reference height is calculated as the height deviation value.

[0109] The reference protrusion height is the height value of the protrusion 2 set by the technician. The height deviation value refers to the deviation value between the moving distance and the reference height. When the moving distance is inconsistent with the reference height, it means that there is a protrusion 2 that exceeds the reference protrusion height. The difference between the moving distance and the reference height is calculated as the height deviation value.

[0110] Step S702: Update the cutting path according to the height deviation value.

[0111] Regenerate the cutting path by the height deviation value.

[0112] Step S703: When the moving distance is consistent with the reference height, other pressure values ​​are collected again.

[0113] When the moving distance is consistent with the reference height, it means that there is no protruding part 2 exceeding the reference protruding height, and other pressure values ​​are re-acquired.

[0114] Step S704: When the other pressure values ​​are less than the squeezing force, the squeezing device is controlled to continue to descend to obtain the inflation supplement distance until the other pressure values ​​are consistent with the squeezing force, and the supplementary movement distance is collected.

[0115] The inflation supplement distance refers to the thickness distance of the airbag that changes when the extrusion device continues to descend, and the supplementary movement distance refers to the distance value of the extrusion device continuing to descend. When the other pressure values ​​are inconsistent with the extrusion force, it means that there is a protrusion 2 that is smaller than the reference protrusion height. The extrusion device is controlled to continue to descend to obtain the inflation supplement distance until the other pressure values ​​are consistent with the extrusion force, and the supplementary movement distance of the extrusion device continuing to descend is retrieved from the displacement sensor of the extrusion device.

[0116] Step S705: Responding to the compaction volume, the reference height, and the moving distance to match the diffusion fatigue of the plasticine.

[0117] Diffusion fatigue refers to the degree of fatigue of the clay when it diffuses. The diffusion fatigue is matched from a preset clay database by the compacted volume, reference height, and moving distance. The clay database stores diffusion fatigue corresponding to different compacted volumes, reference heights, and moving distances. The parameters in the clay database are set by those skilled in the art in advance according to actual conditions, and will not be elaborated here.

[0118] Step S706: Generate a minimum diffusion thickness according to the diffusion fatigue and the extrusion force.

[0119] The minimum diffusion thickness refers to the minimum thickness of the clay when diffusion occurs. The minimum diffusion thickness is matched from the clay database by diffusion fatigue and extrusion strength. The clay database also stores the minimum diffusion thickness corresponding to different diffusion fatigue and extrusion strength, which will not be described here.

[0120] Step S707: obtaining a height reduction parameter by supplementing the moving distance, diffusing the minimum thickness, and inflating the supplement distance, and updating the cutting path according to the height reduction parameter.

[0121] The distance required for the extrusion device to move is updated by the inflation supplement distance, and the sum of the supplementary moving distance and the minimum diffusion thickness is calculated as a height reduction parameter, and then the cutting path is regenerated by the height reduction parameter.

[0122] Reference Fig. 9 , the method of controlling the extrusion device to continue to descend includes: Step S800: Retrieving the protruding area of ​​the claw from the manufacturing parameters.

[0123] The protruding area refers to the area of ​​a single protruding portion 2 facing the airbag device, and the protruding area of ​​the claw is retrieved from the manufacturing parameters.

[0124] Step S801: Responding to other pressure values, pressure detection values ​​and squeezing forces to obtain a deviation amount.

[0125] The deviation number refers to the number of protruding parts 2 where the height reduction parameter appears, and the number of pressure values ​​less than the squeezing force is retrieved from other pressure values ​​and pressure detection values ​​as the deviation number.

[0126] Step S802: Obtaining a total contact area in response to the protrusion area and the deviation amount.

[0127] The total contact area refers to the total contact area of ​​the protrusion 2, the plasticine and the airbag before the extrusion device continues to descend. The total contact area is obtained by analyzing the protrusion area and the number of deviations. For example, the plasticine between the protrusions 2 without deviation will also contact the airbag, and the contact area includes the area of ​​the gap between the protrusions 2.

[0128] Step S803: Responding to the inflation amount and the preset reference inflation amount to obtain the inflation replenishment distance.

[0129] The reference inflation volume is the inflation volume set by the technician to inflate the airbag device to the maximum thickness of the airbag. The inflation supplement distance refers to the thickness of the airbag device extended when the airbag device is inflated to the maximum thickness of the airbag. The inflation supplement distance is matched from the inflation database by the inflation volume and the reference inflation volume. The inflation database also stores the inflation supplement distances corresponding to different inflation volumes at the reference inflation volume.

[0130] Step S804: Calculate the product of the inflation replenishment distance and the total contact area to obtain the total contact volume, and update the total contact volume with a preset unit movement distance.

[0131] The unit moving distance is the distance that the extrusion device moves set by the technician. The total contact volume refers to the total volume of the protruding portion 2 that is sunk into the airbag device. The total contact volume is obtained by calculating the product of the inflation replenishment distance and the total contact area, and the total contact volume is updated by the unit moving distance. The larger the unit moving distance, the larger the volume of the total contact area sunk into the airbag.

[0132] Step S805: Obtain the marked inflation volume according to the updated total contact volume and the reference inflation volume.

[0133] The marked inflation amount refers to the maximum inflation amount required to maintain the maximum thickness of the part of the airbag that is not in contact with the total contact area. The marked inflation amount is matched by inputting the updated total contact volume and the benchmark inflation amount into the inflation database. The inflation database also stores the marked inflation amounts corresponding to different total contact volumes and benchmark inflation amounts, which will not be elaborated here.

[0134] When the thickness of the portion of the airbag that is not in contact with the total contact area remains unchanged, the larger the total contact volume, the smaller the amount of inflation required for the portion of the airbag that is not in contact with the total contact area at the maximum thickness.

[0135] Step S806: Calculate the difference between the inflation amount and the marked inflation amount and use it as the supplementary inflation amount. When the squeezing device continues to descend, inflate and deflate the airbag device with the supplementary inflation amount.

[0136] The supplementary inflation volume refers to the amount of inflation that needs to be supplemented for the airbag. The difference between the inflation volume and the marked inflation volume is calculated as the supplementary inflation volume, and the airbag device is inflated and deflated with the supplementary inflation volume when the squeezing device continues to descend. When the total contact volume is larger, the marked inflation volume is smaller, and the supplementary inflation volume is smaller. If the airbag has been fully inflated, the airbag needs to be deflated to maintain the marked inflation volume.
