[0002] Rolling bearing is a precision mechanical component that reduces friction loss and improves mechanical efficiency by converting the sliding friction between the shaft and the shaft seat into rolling friction.

[0048] By adopting the above technical solution, by obtaining the grinding image information and surface image information, the change of the rust area before and during the grinding of the component can be known, so as to know the remaining grinding depth and then know the height value of the component after grinding. Then, by understanding the size relationship between the height value after grinding and the reference height value, the qualification of the component after grinding can be known. If it is unqualified, the component is moved to the waste recycling area for recycling, so as to further improve the grinding efficiency.

[0049] Optionally, when the rust thickness value is greater than the reference thickness value, the rust characteristics greater than the reference thickness value are adjusted using a preset adjustment method, and the adjustment method includes:

[0057] By adopting the above technical solution, when the rust thickness value is greater than the reference thickness value, the rust removal method is known by understanding the size relationship between the rust thickness value and the excessive thickness value. When the rust thickness value is greater than the excessive thickness value, the rust removal reagent and the reagent dosage value are known through the rust thickness value, and then the rust removal equipment is controlled to spray the rust characteristics, and after spraying, the reagent dosage values ​​are sorted from small to large to obtain the eradication order, and then the rust characteristics are eradicated, thereby improving the rust removal efficiency.

[0058] Optionally, also include:

[0067] By adopting the above technical solution, the working state of the grinding device can be known by understanding the consistency between the state signal and the working signal. When they are consistent, the magnetic device is placed in the waste drop area. Then, by understanding the waste drop area and the position of the components, the blowing angle is known, and then the air is blown in the direction of the waste drop area to absorb the waste dropped by grinding. Then, by understanding the excess between the magnetic attraction density information and the reference density information, the magnetic attraction of the magnetic device is known. In this way, the waste treatment efficiency is improved.

[0076] By adopting the above technical solution, the suction condition of the magnetic device can be known by understanding the size relationship between the remaining magnetic suction area and the required magnetic suction area. When the waste dropped by the next grinding cannot be absorbed, and when the state signal is consistent with the standby signal, the magnetic device is moved to the demagnetization recovery area for demagnetization, and the magnetic device is controlled to vibrate with a vibration amplitude to drop the waste on the magnetic device into the demagnetization recovery area. This improves the waste processing efficiency.

[0099] The following is combined with Figure 1-Figure 7 The present invention is further described in detail with examples.

[0100] The embodiment of the present application discloses a method for manufacturing a rolling bearing, and the rust feature is processed accordingly by understanding the thickness of the rust feature. When grinding, the component is fixed by an external clamping device and an internal clamping device, and after fixation, the rust feature is grinded. And when the component is uneven, the lowest height value of the component is used as the reference height of the component for fixed grinding. Then, by knowing the change in the rust area before and after grinding, the remaining grinding depth is calculated, and then the qualification of the component is known. When the rust thickness value is too large, rust is removed by using a rust removal agent. During grinding, the waste material dropped by grinding is sucked by a magnetic suction device.

[0101] Reference Figure 1 , a method for manufacturing a rolling bearing, comprising the following steps:

[0102] Step 100: Obtain surface image information of a component.

[0103] The component refers to a ring used to make a rolling bearing. The surface image information refers to images of the upper and lower surfaces of the component. The surface image information is obtained by taking a picture with a camera.

[0104] Step 101: Determine whether to complete the inspection or select the rust area based on the inclusion between the surface image information and the preset rust features.

[0105] Rust features refer to features when rust appears on the surface of a component. Rust features are set in advance by those skilled in the art and will not be described in detail here. Whether the surface of a component is rusted can be determined by determining whether the surface image information and the rust features are included.

[0106] If the surface image information does not contain rust features, it means that there is no rust on the surface of the component and the rust inspection is completed.

[0107] If the surface image information contains rust features, it means that there is rust on the surface of the component, and the rusty area with rust features needs to be selected from the surface image information. The rusty area refers to the area on the surface of the component where rust features exist. The rusty area on the component where rust features exist can be selected using the surface image information.

[0108] Step 102: Obtain a rust thickness value based on the rust area.

[0109] The rust thickness value refers to the thickness of the rust feature in the rusted area. The rust thickness value can be obtained by scanning the rusted area with a preset laser scanner.

[0110] Step 103: Determine whether the rust thickness value is greater than a preset reference thickness value.

[0111] The reference thickness value refers to the thickest thickness that the rust feature can be directly polished. Different rust removal methods are selected according to different thicknesses. The specific rust removal methods are described in detail in subsequent steps 1031 to 1034. The reference thickness value is set in advance by those skilled in the art and will not be described in detail here. By judging whether the rust thickness value is greater than the reference thickness value, it is known whether to directly polish the rust feature.

[0112] Step 1031: If the rust thickness value is not greater than the reference thickness value, the rust area is polished using a preset polishing method.

[0113] If the rust thickness value is not greater than the reference thickness value, it means that the rust feature can be directly polished, and the preset polishing device is controlled to polish the rusted area with the preset polishing method. The polishing method is described in detail in the subsequent steps of this implementation, and will not be repeated here.

[0114] Step 1032: If the rust thickness value is greater than the reference thickness value, a removal path is determined based on the surface image information and the rust characteristics.

[0115] If the rust thickness value is greater than the reference thickness value, it means that grinding the rust feature directly consumes too much time, and the removal path needs to be determined by the surface image information and the rust feature. The removal path refers to the path from the starting point to the end point when removing the rust feature. The removal path of the rust feature can be identified by the surface image information.

[0116] Step 1033: Control the preset scraping device to scrape the rust features along the scraping path, and update the surface image information after the scraping.

[0117] The scraping device refers to a scraper used to scrape away rust features. The scraping device is controlled to scrape away the rust features along a scraping path, and after scraping, the surface image information is reacquired.

[0118] Step 1034: Determine whether to complete the removal or update the rust thickness value based on the inclusion between the updated surface image information and the rust features.

[0119] By judging the inclusion between the updated surface image information and the rust features, it is known whether the component still contains the rust features.

[0120] If the updated surface image information does not contain rust features, it means that the removal of the rust features is completed.

[0121] If the updated surface image information contains rust features, it means that the component still contains rust features, and the rust thickness value needs to be updated and steps 103 to 1034 are repeated until the removal is completed.

[0122] Reference Figure 2 , the grinding method comprises the following steps:

[0123] Step 200: Obtain component height information of the component.

[0124] The component height information refers to the height from the bottom to the top when the component is located on a horizontal plane. The component height information can be obtained by scanning with a preset laser scanner.

[0125] Step 201: Determine the centerline position of the component according to the component height information and mark it, and define it as an external marking line.

[0126] The centerline position of a component refers to the position between the bottom and top of the component. The height of the component can be known through the component height information, and then the height of the component is divided by two. The quotient is the middle of the component, and then the centerline position of the component is obtained. The centerline position of the component is marked by a laser instrument, and the mark is defined as the external marking line. The external marking line refers to the marking line of the outer circle of the component.

[0127] Step 202: Determine the internal marking line according to the external marking line and the component height information.

[0128] Internal marking lines refer to the marking lines on the inner circle of a component. Internal marking lines correspond to external marking lines, and the internal marking lines corresponding to external marking lines can be known through component height information.

[0129] Step 203: Control a preset external clamping device to identify the external marking line, and move to the external marking line to clamp the outside of the component.

[0130] The external clamping device refers to a mechanical arm used to clamp the outside of a component. The camera set on the external clamping device is controlled to recognize the external marking line, and the external clamping device is controlled to move to the external marking line to clamp the outside of the component.

[0131] Step 204: Control the preset internal clamping device to move to the internal marking line to tension the inside of the component outward.

[0132] The internal clamping device refers to a chuck used to tension and fix the component outward. The internal clamping device is controlled to move to the internal marking line to tension the inside of the component outward, and then the component is fixed in cooperation with the external clamping device.

[0133] Step 205: After clamping, cancel the mark and control the preset grinding device to move to the preset grinding position.

[0134] The grinding device refers to a grinding wheel used to grind a component. The grinding position refers to the position where the grinding device needs to be when the grinding device is grinding a component. The grinding position is set in advance by a person skilled in the art and will not be described in detail here. After the clamping is fixed, the mark on the component is removed and the grinding device is controlled to move to the grinding position for subsequent grinding.

[0135] Step 206: At the grinding position, control the grinding device to grind the component with a preset grinding force and a preset grinding feed rate, and obtain the grinding angle of the grinding device.

[0136] In this embodiment, when the grinding device grinds the component for the first time, it first contacts the grinding surface of the component in parallel, and then knows the grinding angle of the grinding surface. After knowing the grinding angle, the grinding device is controlled to be adjusted to be parallel to the horizontal plane, and then the grinding surface of the component is ground until the component is ground flat.

[0137] The grinding force refers to the speed of the grinding device when grinding. The grinding feed rate refers to the distance that the grinding device moves toward the component when grinding. The grinding force and the grinding feed rate are both set in advance by technicians in this field and will not be elaborated here. When the grinding device is in the grinding position, the grinding device is controlled to grind the component with the grinding force and the grinding feed rate, and the grinding angle of the grinding device is obtained. The grinding angle refers to the inclination of the grinding device when the grinding device is grinding the component. The grinding angle is obtained by the inclination sensor set on the grinding device.

[0138] In this embodiment, the grinding device is located above the component, the component is clamped and not moved, and the grinding device grinds the component from above.

[0139] Step 207: Determine whether to continue grinding or control the grinding device to exit to a preset safety position according to the consistency between the grinding angle and the preset reference angle.

[0140] The reference angle condition refers to the condition when the grinding device is not tilted. The reference angle condition is set in advance by a person skilled in the art and will not be described in detail here. By judging the consistency between the grinding angle condition and the reference angle condition, it is known whether the current grinding surface of the component is polished flat.

[0141] If the grinding angle is consistent with the reference angle, it means that the current grinding surface of the component has been polished flat, and the grinding device needs to be controlled to withdraw to a safe position. The safe position refers to the position where the grinding device and the component will not affect each other when the external clamping device flips the component. The safe position is set in advance by a technician in this field and will not be described in detail here.

[0142] If the grinding angle is inconsistent with the reference angle, it means that the current grinding surface of the component is not smooth and needs to be further polished.

[0143] Step 208: After exiting to the safety position, control the external clamping device to flip the component, and control the grinding device to move to the grinding position again.

[0144] When the grinding device is withdrawn to the safe position, the external clamping device is controlled to flip the component, and the grinding device is controlled to move to the grinding position again to grind the other side of the component until both sides are polished flat to complete the grinding of the component.

[0145] The bottom and top surfaces of the components in steps 200 to 208 are parallel to the horizontal plane and there is no inclination.

[0146] Reference Figure 3 The grinding method further comprises the following steps:

[0147] Step 300: Determine the highest value and the lowest value of the component according to the component height information.

[0148] The bottom surface and / or the top surface of the component in steps 300 to 308 is inclined.

[0149] The highest value of a component refers to the value at the highest point when the component is tilted upward. The lowest value of a component refers to the value at the lowest point when the component is tilted upward. The highest value and the lowest value of a component can be obtained through the component height information.

[0150] Step 301: Calculate the difference between the highest value of the component and the lowest value of the component, and define the difference as the basic grinding value.

[0151] The basic grinding value refers to the value at which the component is ground straight when it is ground. The basic grinding value can be obtained by subtracting the difference between the highest value of the component and the lowest value of the component.

[0152] Step 302: Determine the component base height according to the component height information and the component lowest value.

[0153] The component base height refers to the distance from the lowest value of the component on one side to the lowest value of the component on the other side. The component base height can be obtained through the component height information and the component lowest value.

[0154] Step 303: Update the external marking line according to the component base height.

[0155] Divide the component base height by two and use the quotient to update the component centerline position to update the external marker line.

[0156] Step 304: Update the internal marking line according to the updated external marking line and the component base height.

[0157] The internal marking line corresponds to the external marking line of the component under the component base height, and the internal marking line can be updated synchronously by updating the external marking line and the component base height.

[0158] Step 305: Control the external clamping device to identify the external marking line, and move to the external marking line to clamp the outside of the component.

[0159] The camera on the external clamping device is controlled to identify the external marking line, and moves to the external marking line to clamp the outside of the component.

[0160] Step 306: Control the internal clamping device to move to the internal marking line to tension the inside of the component outward.

[0161] The internal clamping device is controlled to move to the internal marking line to tighten and fix the inside of the component outward.

[0162] Step 307: After clamping, cancel the mark and control the grinding device to move to the grinding position.

[0163] After the clamping is completed, the mark on the component is cancelled and the grinding device is controlled to move to the grinding position for subsequent grinding.

[0164] Step 308: At the grinding position, control the grinding device to grind the component according to the basic grinding value.

[0165] When the grinding device is in the grinding position, the grinding device is controlled to grind the component with the basic grinding value.

[0166] Reference Figure 4 The grinding method further comprises the following steps:

[0167] Step 400: Determine the rust area according to the surface image information and the rust characteristics.

[0168] The rust area refers to the area of ​​the component occupied by the rust feature. The rust feature can be compared with a preset reference through the surface image information to obtain the rust area. The surface image information includes a reference, and the size of the reference is set in advance by a person skilled in the art, which will not be described in detail here.

[0169] Step 401: Based on the polishing position, control the polishing device to polish the component along a preset polishing path, and obtain polishing image information when the polishing device is located at a preset shooting position in the polishing path.

[0170] When the grinding device is located at the grinding position, the grinding device is controlled to grind the component with a preset grinding path, and the grinding image information is obtained when the grinding device is located at a preset shooting position in the grinding path. The grinding path refers to the path of the grinding device when the grinding device is grinding the component. The grinding device moves from a position close to the component to a direction away from the component. When the grinding device moves away from the position where it does not block the component, the grinding device approaches the component and moves away again, and repeats this movement. The shooting position refers to the position where the grinding device does not block the component when it moves on the grinding path. The grinding path and the shooting position are both set in advance by those skilled in the art and will not be described in detail here. The grinding image information refers to the image of the grinding device when it is grinding the component. When the grinding device is located at the shooting position, the component is photographed by a camera to obtain the grinding image information.

[0171] Step 402: Determine whether to complete the grinding or update the rust area according to the inclusion between the grinding image information and the rust feature.

[0172] Whether the grinding is completed is determined by judging the inclusion between the grinding image information and the rust features.

[0173] If the polishing image information does not contain rust features, it means that the polishing is completed and the subsequent process can be carried out.

[0174] If the polishing image information contains rust features, it means that the polishing is not completed, and the rust area of ​​the rust feature is updated through the polishing image information.

[0175] Step 403: Calculate the difference between the rust area before updating and the rust area after updating, and define the difference as the rust removal value.

[0176] The Rust Removal Value is the value of the rust area removed after the part is polished. The Rust Removal Value is calculated by subtracting the rust area before the update from the rust area after the update.

[0177] Step 404: Match the remaining grinding depth from a preset grinding database according to the rust removal value, the updated rust area and the preset single grinding depth.

[0178] The single grinding depth refers to the depth of the component that the grinding device grinds once along the grinding path. The remaining grinding depth refers to the depth required to remove the rust. The rust removal value, the updated rust area, and the remaining grinding depth corresponding to the single grinding depth can be matched through the grinding database. The grinding database contains the corresponding relationship between the rust removal value, the updated rust area, the single grinding depth, and the remaining grinding depth. The grinding database is a manually set database and will not be described in detail here.

[0179] Step 405: Obtain the current real-time height information of the component.

[0180] Real-time height information refers to the height of the component after grinding. Real-time height information is obtained by scanning the component with a laser scanner.

[0181] Step 406: Calculate the difference between the real-time height information and the remaining grinding depth, and define the difference as the post-grinding height value.

[0182] The height after grinding refers to the height of the component after grinding. The height after grinding is calculated by subtracting the difference between the real-time height information and the remaining grinding depth.

[0183] Step 407: According to the size relationship between the post-grinding height value and the preset reference height value, the grinding device is controlled to grind the component with the remaining grinding depth or to move the component to a preset waste recovery area.

[0184] The reference height value refers to the reference height when the component is qualified. The reference height value is set in advance by those skilled in the art and will not be described in detail here. By judging the size relationship between the height value after grinding and the reference height value, it is known whether the component needs to be further ground.

[0185] If the height value after grinding is not less than the reference height value, it means that the component can continue to be ground, and the grinding device can be controlled to grind the component with the remaining grinding depth.

[0186] If the height after grinding is less than the reference height, it means that the size of the part after grinding is unqualified. There is no need to continue grinding the part. The preset robot arm is controlled to move the part to the waste recycling area for recycling. The waste recycling area refers to the area used to recycle parts with unqualified sizes and waste dropped by grinding.

[0187] Reference Figure 5 When the rust thickness value is greater than the reference thickness value, the method further includes adjusting the rust characteristics greater than the reference thickness value using a preset adjustment method, the adjustment method including the following steps:

[0188] Step 500: When the rust thickness value is greater than the reference thickness value, determine whether the rust thickness value is greater than a preset excessive thickness value.

[0189] The overthickness value refers to the thickness of the rust feature that cannot be directly removed. When the rust thickness value is greater than the reference thickness value, it is determined whether the rust thickness value is greater than the overthickness value to determine whether the rust feature can be directly removed.

[0190] Step 501: If the rust thickness value is not greater than the excessive thickness value, the removing device is controlled to remove the rust features along the removing path.

[0191] If the rust thickness value is not greater than the over-thickness value, it means that the rust feature can be directly removed, and the removing device is controlled to remove the rust feature along the removing path.

[0192] Step 502: If the rust thickness value is greater than the excessive thickness value, a rust removal agent and an agent dosage value are matched from a preset rust removal database according to the rust thickness value.

[0193] If the rust thickness value is greater than the over-thickness value, it means that the rust feature cannot be removed. The rust removal reagent and reagent dosage value corresponding to the rust thickness value need to be matched through the rust removal database. Rust removal reagent refers to the reagent used to corrode rust features. The reagent dosage value refers to the dosage of the rust removal reagent. The rust removal database contains the correspondence between the rust removal reagent and the reagent dosage value and the rust thickness value. The rust removal database is a manually set database and will not be described here.

[0194] Step 5021: Determine the reagent usage location based on the rust area and rust characteristics.

[0195] The reagent application location refers to the location where the rust removal reagent is applied to the rust feature. The location of the rust feature can be known through the rust area, and then the reagent application location can be known.

[0196] Step 5022: Control the preset rust removal equipment to move to the reagent use position, and after the movement is completed, control the rust removal equipment to spray the rust features with the rust removal reagent and the reagent dosage value.

[0197] Rust removal equipment refers to a sprayer used to spray rust removal reagents. The rust removal equipment is controlled to move to the reagent use position, and after the movement is completed, the rust removal equipment is controlled to spray the rust characteristics with the rust removal reagent and the reagent dosage value.

[0198] Step 5023: After the preset spraying time, determine the order of removal from small to large according to the size relationship of the reagent dosage values.

[0199] The spraying time refers to the time that the rust removal reagent adheres to the rust feature after spraying. The spraying time is set in advance by a person skilled in the art and will not be described in detail here. The eradication order refers to the order in which the eradication device eradicates the rust features. The reagent dosage values ​​used for each rust feature are sorted from small to large, and the eradication device is controlled to eradicate the rust features from small to large, thereby obtaining the eradication order.

[0200] The area of ​​the rust feature corresponding to the small reagent dosage value is small, so the rust removal reagent corrodes it quickly, and vice versa. Therefore, the rust removal is carried out from small to large, so that the rust removal reagent corrodes the rust features completely.

[0201] Step 5024: Control the scraping device to scrape away the rust features along the scraping path according to the scraping sequence.

[0202] The eradication device is controlled to eradicate the rust features along an eradication sequence and an eradication path.

[0203] Reference Figure 6 The method for handling the waste material dropped by grinding includes the following steps:

[0204] Step 600: Obtain a status signal of a grinding device.

[0205] The status signal refers to the signal of the grinding device when it is grinding or in standby mode. The status signal is obtained through the signal transceiver in the grinding device.

[0206] Step 601: Determine whether to continue acquiring the state signal of the grinding device or to acquire the waste falling area according to the consistency between the state signal and the preset working signal.

[0207] The working signal refers to the signal when the grinding device is performing grinding work. The working signal is set in advance by a person skilled in the art and will not be described in detail here. By judging the consistency between the state signal and the working signal, it is known whether the grinding device is grinding the component.

[0208] If the status signal is inconsistent with the working signal, it means that the grinding device is not grinding the component, and the status signal of the grinding device can be continued to be obtained.

[0209] If the status signal is consistent with the working signal, it means that the grinding device is grinding the component, and the waste drop area needs to be obtained. The waste drop area refers to the area where the waste drops when the component is ground. The corresponding position when the waste drops can be obtained through the grinding position, and then the waste drop area can be obtained.

[0210] Step 602: Control a preset magnetic suction device to be placed into the waste falling area according to the waste falling area.

[0211] The magnetic suction device refers to an electromagnet used to absorb waste materials. By energizing the electromagnet, it generates magnetism. The preset robotic arm is controlled to place the magnetic suction device into the waste falling area so that the magnetic suction device can absorb the falling waste materials.

[0212] Step 603: Determine the blowing angle according to the waste drop area and the preset component position.

[0213] The component position refers to the position of the component when it is waiting to be polished. The blowing angle refers to the angle at which the preset blowing device blows the waste. Since the blowing device needs to blow the waste dropped by grinding to the magnetic suction device in the waste drop area, the blowing angle can be obtained by the component position and the waste drop area.

[0214] Step 604: Based on the blowing angle, a preset blowing device is controlled to blow air in the direction of the waste falling area with a preset blowing force value.

[0215] The blowing device refers to a fan used to blow the waste onto the magnetic suction device. The blowing force value refers to the wind strength when the blowing device blows. The blowing force value is set in advance by a person skilled in the art and will not be described here. Based on the blowing angle, the blowing device is controlled to blow in the direction of the waste falling area with the blowing force value.

[0216] The blowing force value is set in advance by those skilled in the art. The specific blowing force value needs to be calculated through algorithm configuration. The algorithm configuration is:

[0217] ,in, is the mass of the waste, is the acceleration of the waste, is the acceleration due to gravity, is the air pressure, is the gas constant, is the temperature, is the drag coefficient of the waste, is the windward area of ​​the waste, is the falling speed of the waste, The blowing intensity value.

[0218] The calculation formula for calculating the blowing force required to blow the waste onto the magnetic device. During the falling process, the influence of wind speed on the movement of the object is reflected in air resistance and temperature, so the formula Changes to

[0219] The blowing force value is calculated by the formula. Among them, , , , , , , as well as All are measured and obtained in advance by technicians in this field. Acquired in real time through temperature sensor.

[0220] Step 605: Obtain density image information of the magnetic attraction device.

[0221] The density image information refers to the image of the surface of the magnetic device, and the density image information is obtained by taking a picture with a camera.

[0222] Step 606: Determine magnetic attraction density information according to the density image information and the preset magnetic attraction device characteristics.

[0223] The magnetic device feature refers to the feature of the existence of the magnetic device. The magnetic device feature is set in advance by a person skilled in the art and will not be described in detail here. The magnetic density information refers to the density of the waste on the surface of the magnetic device. The magnetic density information can be obtained through the density image information and the magnetic device feature.

[0224] Step 607: Determine whether to continue magnetic attraction or replace the magnetic attraction device according to the excess between the magnetic attraction density information and the preset reference density information, and update the density image information.

[0225] The reference density information refers to the reference density when the magnetic device needs to be replaced. The reference density information is set in advance by a person skilled in the art and will not be described in detail here. By judging the excess between the magnetic density information and the reference density information, it is known whether the magnetic device needs to be replaced.

[0226] If the magnetic density information does not exceed the reference density information, it means that there is no need to replace the magnetic device and you can continue to use the current magnetic device.

[0227] If the magnetic absorption density information exceeds the reference density information, it means that the magnetic absorption device needs to be replaced. In this embodiment, the magnetic absorption device has two sides. When the magnetic absorption density information of one side exceeds the reference density information, the control robot arm flips the magnetic absorption device. If the magnetic absorption density information of both sides exceeds the reference density information, the magnetic absorption device is replaced. The replacement of the magnetic absorption device is achieved by controlling the two robotic arms. When the new magnetic absorption device reaches the waste drop area, the control robot arm moves the magnetic absorption device whose magnetic absorption density information on both sides exceeds the reference density information out of the waste drop area. The density image information is updated and steps 606 to 607 are repeated.

[0228] Reference Figure 7 , the processing method of the magnetic attraction device comprises the following steps:

[0229] Step 700: Obtain the waste material drop situation of a single grinding waste material drop and the remaining magnetic attraction area of ​​the magnetic attraction device.

[0230] The waste drop situation refers to the total amount of waste dropped during a single grinding of the component. The remaining magnetic attraction area refers to the area where the magnetic device can still attract waste. The waste drop situation is obtained by comparing the density change on the surface of the magnetic device before and after the previous single grinding. The remaining magnetic attraction area is calculated by subtracting the difference between the total area of ​​the magnetic device that can absorb waste on both sides and the area of ​​the magnetic device occupied by the waste.

[0231] Step 701: Determine the required magnetic attraction area according to the waste falling situation.

[0232] The required magnetic suction area refers to the area required to absorb all the waste dropped in a single time. The corresponding required magnetic suction area can be matched from the preset waste database according to the waste dropping situation. The waste database contains the required magnetic suction area corresponding to the waste dropping situation. The waste database is a manually set database and will not be described in detail here.

[0233] Step 702: Determine whether the remaining magnetic attraction area is greater than the required magnetic attraction area.

[0234] By judging whether the remaining magnetic area is larger than the required magnetic area, you can know whether you need to replace or flip the magnetic device in advance to avoid the situation where the magnetic device is full and still drops waste during grinding.

[0235] Step 7021: If the remaining magnetic attraction area is larger than the required magnetic attraction area, continue to absorb the waste.

[0236] If the remaining magnetic suction area is larger than the required magnetic suction area, it means that there is no need to replace the magnetic suction device in advance and the waste can continue to be absorbed.

[0237] Step 7022: If the remaining magnetic attraction area is not greater than the required magnetic attraction area, then based on the state signal being consistent with the preset standby signal, the magnetic attraction device is controlled to move to the preset demagnetization recovery area.

[0238] If the remaining magnetic area is not larger than the required magnetic area, it means that the magnetic device needs to be replaced in advance. When the status signal of the grinding device is consistent with the standby signal, the control arm moves the magnetic device to the demagnetization recovery area and replaces the new magnetic device. The standby signal is a signal that the grinding device is not performing a grinding operation. The demagnetization recovery area is an area used to demagnetize the magnetic device and recover the waste on the magnetic device.

[0239] Step 7023: In the demagnetization recovery area, control the magnetic device to demagnetize, and vibrate with a preset vibration amplitude to drop the waste on the magnetic device into the demagnetization recovery area.

[0240] The vibration amplitude refers to the amplitude when the mechanical arm clamps the magnetic device and vibrates. When the magnetic device is in the demagnetization recovery area, the magnetic device is controlled to stop energizing to complete the demagnetization of the electromagnet, and the mechanical arm holding the magnetic device is controlled to vibrate with the vibration amplitude to drop the waste on the magnetic device into the demagnetization recovery area.

[0241] Step 7024: After demagnetization is completed, the magnetic device is placed in a preset material preparation area.

[0242] The material preparation area is an area for storing magnetic devices. After demagnetization is completed, the robot arm is controlled to place the magnetic device into the material preparation area.
