Description

Technical Field

[0001] The present invention relates to the field of plate cutting, and in particular to a plate arrangement cutting method, system and cutting machine. Background Art

[0002] Sheet cutting refers to the process of using various tools and equipment to cut sheets into specific sizes and shapes. Sheet layout refers to the activity of rationally planning and arranging the parts that need to be cut on the sheet during production or processing.

[0003] In the prior art, when parts are cut on a plate, they usually need to be arranged on the plate. However, considering that a large amount of heat will be generated when adjacent parts are cut, which will affect the adjacent parts, the arrangement distance between adjacent parts needs to be increased.

[0004] Regarding the above-mentioned related technologies, since the arrangement distance between adjacent parts is increased, the utilization rate of the plate and the productivity of the parts are reduced, which needs to be improved. Summary of the invention

[0005] In order to improve the utilization rate of the plate, the present invention provides a plate arrangement and cutting method.

[0006] In a first aspect, the present invention provides a plate arrangement and cutting method, which adopts the following technical solution:

[0010] Determine the safe distance based on the laser power;

[0011] Analyze the preset arrangement database according to the plate parameters, preset component parameters and safety distance to obtain the arrangement position of the components and the number of reference components;

[0012] Determine the placement position of the preset heat dissipation device and the cutting position for processing according to the arrangement position;

[0013] The heat dissipation temperature value is determined according to the preset heat dissipation power, and the heat dissipation temperature value corresponding to the heat dissipation power can be matched through the preset heat dissipation database, wherein the greater the heat dissipation power, the greater the heat dissipation temperature value;

[0014] The transfer temperature value is calculated based on the plate parameters, processing temperature value and heat dissipation temperature value. Since the thermal conductivity of different materials is different, the transfer temperature value can be obtained by calculating the quotient between the processing temperature value and the heat dissipation temperature value under different plate parameters;

[0015] The safety distance is updated according to the transferred temperature value, and the updated safety distance corresponding to the transferred temperature value can be matched through a preset distance database, and the distance database contains the corresponding relationship between the transferred temperature value and the updated safety distance;

[0016] Analyze from a preset arrangement database according to plate parameters, component parameters and updated safety distance to update the component arrangement position and reference component quantity, and define the updated reference component quantity as the compact component quantity;

[0017] According to the excess relationship between the number of compact parts and the number of reference parts, the heat dissipation device is controlled to move to the placement position or the cutting device is controlled to perform cutting at the cutting position corresponding to the number of reference parts;

[0018] After the heat sink is moved to the placement position, the heat sink is controlled to dissipate heat using a preset heat dissipation method, and the cutting device is controlled to cut at an updated cutting position.

[0019] By adopting the above technical solution, the arrangement position of the parts on the plate and the number of reference parts can be known by understanding the plate parameters, part parameters and safety distance. Then, the heat dissipation device is used to dissipate heat between adjacent parts. And by understanding the plate parameters, processing temperature value and heat dissipation temperature value, the transfer temperature value is calculated to shorten the safety distance, thereby increasing the number of parts and improving the utilization rate of the plate.

[0020] Optionally, the method for correcting the updated arrangement position includes:

[0021] Obtaining detection image information of the plate to be cut;

[0022] Determine the completion of placement or select abnormal features from the detected image information based on the consistency between the detected image information and the preset reference image information;

[0023] Match the abnormal type from the preset abnormal database according to the abnormal characteristics;

[0024] Matching adjustment methods from a preset adjustment database according to the abnormality type;

[0025] Control the clamping device to adjust the plate to be cut according to the adjustment method to complete the placement;

[0026] After the placement is completed, the cutting device is controlled to perform cutting at the updated cutting position, and after the current workpiece is cut, the workpiece to be cut is determined according to the updated arrangement position;

[0027] Determine the edge position according to the workpiece to be cut, the workpiece parameters and the updated safety distance;

[0028] Obtain cutting image information based on edge position;

[0030] After grinding, obtain the smoothness of the cut edge;

[0031] According to the excess relationship between the post-grinding flatness and the preset reference flatness, the cutting device is controlled to continue cutting at the updated cutting position or the arrangement position is updated based on the cutting image information and the cutting edge.

[0032] By adopting the above technical solution, the placement of the plate is known by understanding the consistency between the detection image information and the reference image information. When the plate is placed abnormally, the adjustment method is known by understanding the type of abnormality, and the plate is corrected by the adjustment method to complete the placement. After the placement is completed and the workpiece is cut, the damage of the edge position is known by understanding the inclusion between the cutting image information and the damage feature. When no damage occurs, the grinding device is controlled to grind the cut edge, and the update of the arrangement position is known by understanding the excess relationship between the post-grinding flatness and the reference flatness, thereby further improving the utilization rate of the plate.

[0033] Optional processing methods for the workpiece include:

[0034] Get the material information of the board;

[0035] Match the weight value and shape information of the workpiece from the preset workpiece database according to the material information and workpiece parameters;

[0036] According to the weight value of the workpiece, the blowing force value is matched from the preset blowing database;

[0037] Determine the blowing force area based on shape information and part weight;

[0038] Dividing the blowing area of ​​the preset blowing device based on the updated arrangement position;

[0039] Determine the cutting benchmark time based on the plate parameters, workpiece parameters and laser power;

[0040] Based on the cutting benchmark time, the blowing area is updated according to the updated arrangement position, and the blowing outlet corresponding to the blowing area is controlled to align with the blowing force area to blow with the blowing force value, and the blowing force value is reduced at a preset blowing attenuation rate until the blowing force value is zero.

[0041] By adopting the above technical solution, the blowing force value and the blowing force area are known by understanding the weight value and shape information of the workpiece. Then the blowing area of ​​the blowing device is divided by the updated arrangement position so that the blowing device can blow the corresponding workpiece. When the workpiece is cut, the blowing port corresponding to the blowing area is controlled to align with the blowing force area to blow with the blowing force value, and the blowing force value is gradually reduced. In this way, the falling speed of the workpiece is reduced and the bumping of the workpiece is reduced.

[0042] Optionally, the processing method of the workpiece also includes:

[0043] When the workpiece is blown by the air outlet, the blowing image information is obtained;

[0044] Select the features of foreign matter in the wind according to the wind image information;

[0045] Determine whether the characteristics of the foreign matter blown by the air are consistent with the preset reference foreign matter characteristics;

[0046] If the characteristics of the foreign body being blown are inconsistent with the characteristics of the reference foreign body, continue blowing;

[0047] If the characteristics of the foreign body being blown are consistent with the characteristics of the reference foreign body, the flipping force position and the flipping blowing angle of the workpiece are determined according to the shape information;

[0049] During the blowing process, the preset suction device is controlled to move to the upper part corresponding to the blowing area, and the characteristics of the blown foreign matter are transported to the preset recovery area with the preset suction force.

[0050] By adopting the above technical solution, when the blowing port blows air to the workpiece, the blowing condition can be known by understanding the consistency between the characteristics of the foreign matter blown and the characteristics of the reference foreign matter. When they are consistent, it means that foreign matter appears during blowing. By understanding the flipping force position and flipping blowing angle of the workpiece, the auxiliary blowing device is controlled to blow air to the workpiece, so that the workpiece can be flipped, and then the foreign matter of the workpiece can be completely blown away. Then the suction equipment is controlled to suck air and transport the characteristics of the foreign matter blown to the recovery area. The recovery efficiency of foreign matter generated during cutting is improved.

[0051] Optional inspection methods for parts during cutting include:

[0052] Obtaining the detection weight value of the preset collection area;

[0053] Based on the cutting reference time, the detection weight value is updated, and the difference between the updated detection weight value and the detection weight value before the update is calculated, and the difference is defined as the newly added weight value;

[0054] Determine whether the newly added weight value is zero;

[0055] If the newly added weight value is zero, the detected weight values ​​before and after the cutting benchmark time are combined and the detected weight value is recorded once;

[0056] If the added weight value is not zero, the difference is defined as the weight increase value;

[0057] Determine whether the weight growth value is equal to the preset reference growth value;

[0058] If the weight increase value is equal to the baseline increase value, continue cutting according to the cutting position;

[0059] If the weight growth value is not equal to the reference growth value, an overweight abnormal signal or an underweight abnormal signal is output according to the size relationship between the weight growth value and the reference growth value;

[0060] Acquire abnormal image information according to the overweight abnormal signal and the underweight abnormal signal;

[0061] According to the abnormal image information, the abnormal object features are framed and selected, and the preset mechanical arm is controlled to clamp the abnormal object corresponding to the abnormal object features, and the clamping weight value is obtained;

[0062] According to the size relationship between the clamping weight value and the workpiece weight value, the robot arm is controlled to clamp the abnormal object to a preset repair area or to clamp the abnormal object to a preset recycling area.

[0063] By adopting the above technical solution, the cutting and falling conditions of the workpiece can be known by understanding the newly added weight value. When a workpiece falls, the accurate situation of the fall can be known by understanding the consistency between the weight increase value and the benchmark increase value. When there is inconsistency, the abnormal situation of the fall can be known by understanding the size relationship between the weight increase value and the benchmark increase value. Finally, by understanding the weight situation when the foreign object is clamped, the method of handling the foreign object can be known. Improve the efficiency of handling foreign objects.

[0064] Optionally, the processing when the newly added weight value is zero includes:

[0065] When the newly added weight value is zero, the preset lifting device is controlled to lift the cutting position with a preset lifting force;

[0066] During lifting, obtain lifting pressure information;

[0067] Determine the tilt angle of the workpiece based on the jacking pressure information;

[0068] Determine whether the tilt angle of the workpiece is greater than a preset reference tilt angle;

[0069] If the workpiece tilt angle is not greater than the reference tilt angle, a cutting error signal is output to a preset signal transceiver terminal;

[0070] If the workpiece inclination angle is greater than the reference inclination angle, the remaining cutting starting point and the remaining cutting allowance are determined according to the workpiece inclination angle;

[0071] According to the remaining cutting starting point and the remaining cutting allowance, the preset auxiliary cutting equipment is controlled to move to the remaining cutting starting point for cutting.

[0072] By adopting the above technical solution, when the added weight value is zero, it means that the workpiece has not fallen, and the lifting device is controlled to lift the cutting position. By understanding the lifting pressure information, the tilt angle of the workpiece is known, and then by understanding the relationship between the tilt angle of the workpiece and the reference tilt angle, the cutting degree of the workpiece is known. Then the solution is determined. The speed of workpiece production is improved.

[0073] Optional heat dissipation methods include:

[0074] After the heat dissipation device is started, a heat conduction baffle plate preset in the heat dissipation device is controlled to extend toward the plate until it contacts the plate;

[0075] After the extension is completed, obtaining device temperature information of the heat dissipation device;

[0076] Matching the blowing speed from a preset heat dissipation database according to the device temperature information;

[0077] Controlling the preset blowing equipment according to the blowing speed to inflate and blow air to the air inlet of the heat dissipation device;

[0079] Determine the inflation blowing temperature according to the outlet air temperature information;

[0080] According to the inflation blowing temperature, a preset temperature regulating device is controlled to adjust the blowing temperature during inflation blowing;

[0081] Match the degree of atomization from the preset water mist database according to the ambient temperature information;

[0082] The preset spraying equipment on the blowing device is controlled according to the degree of atomization to spray and cool down the air inlet.

[0083] By adopting the above technical solution, the blowing speed is known by understanding the device temperature information, and then the blowing device is controlled to blow air to the air inlet of the heat dissipation device based on the blowing speed. Then, the inflation blowing temperature is known by understanding the air outlet temperature information of the air outlet on the heat dissipation device, and then the blowing temperature is adjusted based on the inflation blowing temperature. Then, the atomization degree is determined by understanding the ambient temperature information of the heat dissipation device, and then the spraying equipment is controlled to spray and cool down the air inlet. In this way, the heat dissipated during cutting is reduced, so that adjacent workpieces can be cut closer, thereby improving the utilization rate of the plate.

[0084] Optionally, also include:

[0085] After the heat dissipation device is started, the difference between the ambient temperature information and the preset reference temperature information is calculated and defined as the cooling temperature value;

[0086] According to the cooling temperature value, the restored wind force value is matched from the preset blowing database;

[0091] By adopting the above technical solution, the reduction wind force value is known by understanding the cooling temperature value. Then, the reduction gas is known by understanding the material information, and then the gas release amount is known. Finally, the blower is controlled to blow air at the blowing position by the reduction wind force value, reduction gas and gas release amount. In this way, the oxidation phenomenon during the production of the product is reduced, and the yield rate of the product is improved.

[0108] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0109] The embodiment of the present application discloses a plate arrangement cutting method, which reduces the heat emitted during cutting by using a heat dissipation device, thereby shortening the distance between adjacent parts to update the arrangement position. When the plate is not placed, the plate is adjusted by a matched adjustment method. After the placement is completed, the plate is cut, and after one cut is completed, the damage of the edge position is known to know whether the edge position needs to be polished, and when necessary, the edge position is polished to further shorten the distance between adjacent parts. After the parts are cut, the parts are blown by using a blowing device. And when blowing, when the blowing foreign body feature appears, the parts are blown to flip, to blow the blowing foreign body feature, and the suction device is controlled to suck the blowing foreign body feature to the recovery area. When the newly added weight value is abnormal, the abnormal situation is understood to deal with the parts with abnormal situation accordingly. When the parts do not fall after cutting, they are lifted by the lifting device to know the reason why they cannot fall. Then the problem of the parts not falling is solved by the corresponding solution. When cutting, the heat generated during cutting is absorbed by the heat dissipation device, and then the heat dissipation device is blown and sprayed by the blowing device and the spraying device on the blowing device to reduce the heat of the heat dissipation device. When cutting, the workpiece is protected by using reducing gas to avoid oxidation of the workpiece.

[0110] Reference Figure 1 , a plate arrangement cutting method comprises the following steps:

[0111] Step 100: Obtaining plate parameters of the plate to be cut.

[0112] The plate to be cut refers to the plate that will be cut by the cutting device to produce the product. The cutting device refers to the laser cutting machine used to cut the plate. The plate parameters refer to the thickness, length and width of the plate. The plate parameters are obtained by scanning the QR code on the plate with a preset scanner. The content after scanning the QR code corresponds to the plate parameters.

[0113] Step 101: Match the laser power and processing temperature values ​​from a preset laser database according to the plate parameters.

[0114] Laser power refers to the power required when the cutting device performs laser cutting on the plate, and the greater the laser power, the higher the penetration depth of the plate. The processing temperature value refers to the processing temperature emitted when the cutting device performs laser cutting on the plate. The laser database contains the correspondence between the plate parameters and the laser power and processing temperature values. The laser database can be used to match the laser power and processing temperature values ​​corresponding to the plate parameters.

[0115] Step 102: Determine a safe distance according to the laser power.

[0116] Safety distance refers to the distance between adjacent parts on the plate. The safety distance corresponding to the laser power can be matched through the preset safety database. The greater the laser power, the greater the safety distance. The safety database is a manually set database and will not be described here.

[0117] Step 103: Analyze the preset arrangement database according to the plate parameters, preset component parameters and the safety distance to obtain the arrangement position of the components and the number of reference components.

[0118] Part parameters refer to the shape and size of the parts to be cut. Arrangement position refers to the position distribution of the parts on the plate. The number of reference parts refers to the number of parts that can be produced from the current plate. When the size of the parts is fixed, the larger the size of the plate, the more parts can be arranged. The arrangement database can analyze the plate parameters, part parameters and safety distance, and then know the arrangement position of the parts and the number of reference parts. The arrangement database is a manually set database and will not be described here.

[0119] Step 104: Determine the placement position of the preset heat dissipation device and the processing cutting position according to the arrangement position.

[0120] The heat sink refers to a partition used to dissipate heat when the plate is cut. The placement position refers to the position where the heat sink is placed on the plate. The cutting position refers to the position where the workpiece is cut on the plate. Since the heat sink needs to be placed between adjacent workpieces to be cut, the placement position of the heat sink can be known through the arrangement position. The arrangement position can be used to know the arrangement of the workpieces on the plate, so as to obtain the cutting position.

[0121] Step 105: Determine a heat dissipation temperature value according to a preset heat dissipation power.

[0122] The heat dissipation power refers to the power of the heat dissipation device when dissipating heat. The heat dissipation temperature value refers to the heat value that the heat dissipation device can dissipate. The heat dissipation power is set in advance by those skilled in the art and will not be described in detail here. The heat dissipation temperature value corresponding to the heat dissipation power can be matched through a preset heat dissipation database, where the greater the heat dissipation power, the greater the heat dissipation temperature value. The heat dissipation database is a manually set database and will not be described in detail here.

[0123] Step 106: Calculate the transfer temperature value according to the plate parameters, the processing temperature value and the heat dissipation temperature value.

[0124] The transfer temperature value refers to the temperature value of the plate when the heat emitted from the current cutting position is transferred to the next cutting position after heat dissipation during cutting. Since the thermal conductivity of different materials is different, the transfer temperature value can be obtained by calculating the quotient between the processing temperature value and the heat dissipation temperature value under different plate parameters.

[0125] Step 107: Update the safety distance according to the transmitted temperature value.

[0126] Due to the presence of a heat sink, the transfer temperature value will be lower than the processing temperature value, so that adjacent parts can be brought closer together during cutting, thereby updating the safety distance. The distance of approach can be matched to the distance corresponding to the transfer temperature value through a preset distance database, which contains the corresponding relationship between the transfer temperature value and this distance. The distance database is a manually set database and will not be described in detail here.

[0127] Step 108: Analyze from a preset arrangement database according to the plate parameters, the component parameters and the updated safety distance to update the component arrangement position and the reference component quantity, and define the updated reference component quantity as the compact component quantity.

[0128] Since the safety distance is updated, the arrangement position will also be updated accordingly. The arrangement database is used to analyze the plate parameters, component parameters and the updated safety distance to update the arrangement position and the reference component quantity, and the updated reference component quantity is defined as the compact component quantity.

[0129] Step 109: Controlling the heat sink to move to the placement position or controlling the cutting device to perform cutting at the cutting position corresponding to the reference number of parts according to the excess relationship between the number of compact parts and the reference number of parts.

[0130] By determining the excess relationship between the number of compact parts and the number of reference parts, it is determined whether the arrangement position needs to be updated.

[0131] If the number of compact parts exceeds the number of reference parts, it means that the utilization rate of the plate in the updated arrangement position is greater than that before the update. The heat sink can be moved to the placement position by controlling the robot arm.

[0132] If the number of compact parts does not exceed the number of reference parts, it means that the utilization rate of the plate material by the updated arrangement position is not greater than that of the arrangement position before the update. The cutting device can be directly controlled to perform cutting at the cutting position corresponding to the number of reference parts.

[0133] Step 110: After the heat sink is moved to the placement position, the heat sink is controlled to dissipate heat using a preset heat dissipation method, and the cutting device is controlled to cut at an updated cutting position.

[0134] The heat dissipation method refers to the method by which the heat dissipation device dissipates heat when processing the plate. The specific steps of the heat dissipation method are described in detail in the subsequent embodiments and will not be repeated here.

[0135] When the heat dissipation device is moved to the placement position, the heat dissipation device is controlled to dissipate heat from the plate using a heat dissipation method, and the cutting device is controlled to cut at the updated cutting position.

[0136] Reference Figure 2 , the method for correcting the updated arrangement position includes the following steps:

[0137] Step 200: Acquire detection image information of the plate to be cut.

[0138] The detection image information refers to the image of the plate placed on the cutting device. The detection image information is obtained by taking a picture with a camera.

[0139] Step 201: Determine the completion of placement or select abnormal features from the detection image information based on the consistency between the detection image information and the preset reference image information.

[0140] The reference image information refers to the image of the plate after it is placed on the cutting device. The reference image information is obtained by a person skilled in the art by taking a photo in advance. The placement of the plate is known by judging the consistency between the detection image information and the reference image information.

[0141] If the detected image information is consistent with the reference image information, the plate is placed on the cutting device.

[0142] If the detected image information is inconsistent with the reference image information, the plate is not placed neatly on the cutting device, and the plate needs to be adjusted by understanding the abnormal features. The abnormal features refer to the features in the detected image information that are different from the reference image information. The abnormal features are obtained by comparing the differences between the detected image information and the reference image information.

[0143] Step 202: Match the abnormality type from a preset abnormality database according to the abnormality feature.

[0144] The abnormal type refers to the specific reason why the plate is not placed properly. The abnormal database is obtained based on the deep learning of the neural network model, which contains the correspondence between abnormal features and abnormal types. The abnormal database can match the abnormal type corresponding to the abnormal feature. Among them, the abnormal type includes the situation where the plate is placed crookedly and the situation where the plate is tilted. The abnormal database is a manually set database and will not be described here.

[0145] Step 203: Match an adjustment method from a preset adjustment database according to the abnormality type.

[0146] The adjustment method refers to the method used to handle the abnormal type. The adjustment database contains the correspondence between the abnormal type and the adjustment method. The adjustment database can be used to match the adjustment method corresponding to the abnormal type. The adjustment database is a manually set database and will not be described in detail here.

[0147] Step 204: Control the clamping device to adjust the plate to be cut according to the adjustment method to complete the placement.

[0148] The plate to be cut is adjusted by controlling the clamping device to complete the placement. When the abnormality is that the plate is tilted, the adjustment method is to control the clamping device to clamp and lift the plate, then control the clamping device to rotate and adjust, and finally place the rotated plate back on the cutting device. When the abnormality is that one end is tilted, the adjustment method is to control the clamping device to clamp and lift the plate, then control the clamping device to move horizontally, and finally place the moved plate back on the cutting device.

[0149] Step 205: After the placement is completed, the cutting device is controlled to perform cutting at the updated cutting position, and after the current workpiece is cut, the workpiece to be cut is determined according to the updated arrangement position.

[0150] When the plate is placed, the cutting device is controlled to cut the plate at the updated cutting position, and after the current workpiece is cut, the workpiece to be cut is obtained through the updated arrangement position. The workpiece to be cut refers to the next workpiece to be cut after the current workpiece is cut.

[0151] Step 206: Determine the edge position according to the workpiece to be cut, the workpiece parameters and the updated safety distance.

[0152] The edge position refers to the position of the cut workpiece on the plate close to one end of the workpiece to be cut. The workpiece to be cut can be used to know the edge of one end of the workpiece cut on the plate, and then the distance between the workpiece to be cut and the edge position can be known through the workpiece parameters and the updated safety distance, and then the edge position can be obtained.

[0153] Step 207: Obtain cutting image information based on the edge position.

[0154] The cutting image information refers to the image at the edge position, and the cutting image information is obtained by taking a picture with a camera.

[0155] Step 208: Control the cutting device to continue cutting at the updated cutting position or control the preset grinding device to grind the cutting edge at a preset grinding force according to the inclusion between the cutting image information and the preset damage feature.

[0156] The damage feature refers to the damage on the plate after the plate is cut. The damage feature is set in advance by those skilled in the art and will not be described in detail here. By judging the inclusion between the cutting image information and the damage feature, it is known whether the adjacent parts can be brought closer.

[0157] If the cutting image information contains damage features, it means that the current edge position cannot be cut into a qualified product, and there is no need to further adjust the cutting position. The cutting device can be controlled to continue cutting at the updated cutting position.

[0158] If the cutting image information does not contain damage features, it means that the current edge position can be cut into qualified parts, and the grinding device needs to be controlled to grind the cutting edge with grinding force for subsequent cutting. The grinding device refers to an angle grinder used to grind the flatness of the plate. The grinding force refers to the force with which the grinding device grinds the plate. The grinding force is set in advance by a technician in this field and will not be described in detail here.

[0159] Step 209: After grinding is completed, obtain the post-grinding flatness of the cut edge.

[0160] The post-grinding flatness refers to the flatness of the cut edge after grinding. The post-grinding flatness is obtained by scanning with a preset infrared scanning device.

[0161] Step 210: Controlling the cutting device to continue cutting at the updated cutting position according to the excess relationship between the post-grinding flatness and the preset reference flatness, or updating the arrangement position based on the cutting image information and the cutting edge.

[0162] The reference flatness refers to the flatness that the plate needs to reach in order to produce a product. The reference flatness is set in advance by those skilled in the art and will not be described in detail here. By judging the excess relationship between the post-grinding flatness and the reference flatness, it is known whether the cut edge after grinding can be cut into a qualified product.

[0163] If the flatness after grinding exceeds the reference flatness, it means that the cut edge after grinding cannot be cut into a qualified product. The cutting device can be controlled to continue cutting at the updated cutting position.

[0164] If the flatness after grinding does not exceed the reference flatness, it means that the cut edge after grinding can be cut into qualified products, and the arrangement position is updated again through the cutting image information and the cutting edge. In this way, the product to be cut can be tangent to the product cut before the product to be cut, thereby shortening the distance between adjacent products again.

[0165] Reference Figure 3 , the processing method of the workpiece includes the following steps:

[0166] Step 300: Obtain material information of the board.

[0167] Material information refers to the material and weight of the board. The material information is obtained by scanning the barcode on the board with a preset scanner, and the content corresponding to the material information can be obtained by reading the barcode.

[0168] Step 301: Match the weight value and shape information of the workpiece from a preset workpiece database according to the material information and the workpiece parameters.

[0169] The part weight value refers to the weight of a single part. The shape information refers to the shape of the part. The part weight value and shape information corresponding to the material information and part parameters can be matched through the part database. The part database contains the corresponding relationship between material information, part parameters, part weight value and shape information. Inputting material information and part parameters into the part database can match the part weight value and shape information. The part database is a manually set database and will not be described in detail here.

[0170] Step 302: Match the blowing force value from a preset blowing database according to the workpiece weight value.

[0171] The blowing force value refers to the force when blowing on the workpiece. The blowing force value corresponding to the workpiece weight value can be matched through the blowing database. The blowing database contains the corresponding relationship between the workpiece weight value and the blowing force value. The larger the workpiece weight value, the larger the blowing force value. The blowing database is a manually set database and will not be described here.

[0172] Step 303: Determine the blowing force area according to the shape information and the weight value of the workpiece.

[0173] The blowing force area refers to the force position area of ​​the workpiece when the workpiece is blown. The center of gravity of the workpiece can be obtained through the shape information and weight value of the workpiece, so that the best force position of the workpiece can be obtained, and then the blowing force area can be obtained, so that the workpiece can fall smoothly.

[0174] Step 304: Divide the blowing area of ​​the preset blowing device based on the updated arrangement position.

[0175] The blowing device refers to a large fan used to blow air to the workpiece. The blowing area refers to the area divided on the blowing device. Among them, the blowing device is provided with multiple air outlets to control the blowing area. The cutting position of each workpiece can be obtained through the updated arrangement position, and the blowing area is divided accordingly.

[0176] Step 305: Determine a reference cutting time according to the plate parameters, the workpiece parameters and the laser power.

[0177] The cutting reference time refers to the time required to cut a single workpiece. The preset cutting database can match the cutting reference time corresponding to the plate parameters, workpiece parameters and laser power. The cutting database contains the correspondence between the plate parameters, workpiece parameters, laser power and cutting reference time. Among them, when the laser power is fixed, the greater the thickness of the plate and the size of the workpiece in the plate parameters and workpiece parameters, the longer the cutting reference time. The cutting database is a manually set database and will not be elaborated here.

[0178] Step 306: Based on the cutting benchmark time, the blowing area is updated according to the updated arrangement position, and the blowing outlet corresponding to the blowing area is controlled to align with the blowing force area to blow with the blowing force value, and the blowing force value is reduced at a preset blowing attenuation rate until the blowing force value is zero.

[0179] After the cutting reference time has passed, the position of the next workpiece to be cut is obtained through the updated arrangement position, so as to update the corresponding blowing area. And the blowing port corresponding to the blowing area is controlled to blow air at the blowing force value aligned with the blowing force area of ​​the workpiece to slow down the falling speed of the workpiece. The blowing port is provided with a nozzle that can rotate 360°, and the rotation of the nozzle is controlled by the pan-tilt to adjust the blowing angle of the blowing port. At the same time, the blowing device is controlled to reduce the blowing force value at a preset blowing attenuation rate until the blowing force value is zero. The blowing attenuation rate refers to the rate at which the blowing device gradually suspends the blowing force value. The blowing attenuation rate is set in advance by those skilled in the art and will not be elaborated here.

[0180] Reference Figure 4 , the processing method of the workpiece also includes the following steps:

[0181] Step 400: When the workpiece is blown by the blower, the blowing image information is obtained.

[0182] The blowing image information refers to the image of the workpiece when the blowing port of the blowing device blows air to the workpiece. The blowing image information is obtained by taking pictures with a camera.

[0183] Step 401: Select features of foreign matter caused by blowing air according to the blowing image information.

[0184] Blowing foreign body features refer to features other than the workpiece in the image. Blowing foreign body features can be obtained by eliminating the workpiece features through the blowing image information.

[0185] Step 402: Determine whether the characteristics of the foreign matter blown by the air are consistent with the preset reference foreign matter characteristics.

[0186] The reference foreign body feature refers to the feature of the foreign body that needs to be removed. By judging whether the foreign body feature of the blowing foreign body is consistent with the reference foreign body feature, it is known whether the foreign body feature of the blowing foreign body needs to be removed.

[0187] Step 4021: If the characteristics of the foreign body being blown are inconsistent with the characteristics of the reference foreign body, continue blowing.

[0188] If the characteristics of the foreign body being blown are inconsistent with the characteristics of the reference foreign body, it means that the characteristics of the foreign body being blown do not need to be removed and the blowing can be continued.

[0189] Step 4022: If the characteristics of the foreign matter caused by blowing are consistent with the characteristics of the reference foreign matter, the flipping force position and the flipping blowing angle of the workpiece are determined based on the shape information.

[0190] If the characteristics of the foreign body caused by blowing are consistent with the characteristics of the reference foreign body, it means that the characteristics of the foreign body caused by blowing need to be removed. To ensure that it can be removed thoroughly, the workpiece needs to be flipped over, so the flipping force position and flipping blowing angle of the workpiece need to be known. The flipping force position refers to the position where the workpiece is subjected to wind force when the blowing device blows the workpiece over. The flipping blowing angle refers to the angle at which the workpiece is blown over. The shape information can be used to know the position where the workpiece is easily blown over, so the flipping force position and flipping blowing angle of the workpiece can be known.

[0191] Step 4023: Control the auxiliary blowing device preset in the blowing area to blow with a blowing force value according to the flip force position and the flip blowing angle.

[0192] The auxiliary blowing device refers to a fan used to assist in blowing the workpiece to flip. The auxiliary blowing device blows out air through a blowing nozzle. The auxiliary blowing device controls the blowing area to blow air at the flipping force position and flipping blowing angle of the workpiece according to the blowing force value to complete the flipping of the workpiece.

[0193] Step 4024: During the blowing process, the preset suction device is controlled to move to the upper part corresponding to the blowing area, and the characteristics of the blown foreign matter are transported to the preset recovery area with the preset suction force.

[0194] The suction device refers to a fan used to absorb the characteristics of blowing foreign matter and transport it to the recovery area. The recovery area refers to an area used to centrally recover waste materials such as the characteristics of blowing foreign matter. The suction force refers to the force of the suction device when sucking air. The recovery area and the suction force are set in advance by those skilled in the art and will not be described here. When the blowing device is blowing, it controls the preset mechanical arm to clamp the suction device and move it to the top corresponding to the blowing area, and transports the characteristics of blowing foreign matter to the preset recovery area with the suction force.

[0195] The inspection method for the workpiece during cutting includes the following steps:

[0196] Step 500: Obtain the detected weight value of the preset collection area.

[0197] The collection area refers to the area for collecting the finished cut parts. The collection area is set in advance by a person skilled in the art and will not be described in detail here. The detection weight value refers to the weight value of the collection area. The detection weight value is obtained by measuring the weight detector set in the collection area.

[0198] Step 501: based on the cutting reference time, update the detection weight value, calculate the difference between the updated detection weight value and the detection weight value before the update, and define the difference as the newly added weight value.

[0199] Based on the cutting benchmark time, the detection weight value is obtained again, and the difference between the two detection weight values ​​is calculated, and the difference is defined as the new weight value.

[0200] Step 502: Determine whether the newly added weight value is zero.

[0201] By judging whether the newly added weight value is zero, it is known whether a workpiece has fallen after the cutting reference time.

[0202] Step 5021: If the newly added weight value is zero, the detected weight values ​​before and after the cutting reference time are combined, and the detected weight value is recorded once.

[0203] If the newly added weight value is zero, it means that no part has fallen, and the two detected weight values ​​are combined and recorded as one detected weight value until the newly added weight value is not zero.

[0204] Step 5022: If the newly added weight value is not zero, the difference is defined as the weight increase value.

[0205] If the newly added weight value is not zero, it means that an item has fallen in the collection area, and the difference between the newly added weight value and zero is defined as the weight growth value.

[0206] Step 5023: Determine whether the weight growth value is equal to a preset reference growth value.

[0207] The base growth value refers to the weight of a single component. By judging whether the weight growth value is equal to the base growth value, we can know whether the dropped item is a component.

[0208] Step 50231: If the weight growth value is equal to the baseline growth value, continue cutting according to the cutting position.

[0209] If the weight increase value is equal to the baseline increase value, it means that the dropped object is a workpiece, and you can continue cutting the next workpiece according to the cutting position.

[0210] Step 50232: If the weight growth value is not equal to the reference growth value, an overweight abnormal signal or an underweight abnormal signal is output according to the size relationship between the weight growth value and the reference growth value.

[0211] If the weight growth value is not equal to the reference growth value, the relationship between the weight growth value and the reference growth value is determined to determine whether the dropped item is not a manufactured item or whether there are other items besides the manufactured item.

[0212] If the weight increase value is greater than the reference increase value, it means that there are other items besides the workpiece, and an overweight abnormal signal needs to be output. The overweight abnormal signal refers to the abnormal signal issued when the weight increase value is greater than the reference increase value.

[0213] If the weight increase value is less than the reference increase value, it means that the dropped object is not a workpiece, and an underweight abnormal signal needs to be output. An underweight abnormal signal refers to an abnormal signal issued when the weight increase value is less than the reference increase value.

[0214] Step 50233: Obtain abnormal image information based on the overweight abnormal signal and the underweight abnormal signal.

[0215] When any one of the overweight abnormal signal and the underweight abnormal signal is output, abnormal image information is obtained. The abnormal image information refers to the image of the object that outputs the abnormal signal. The abnormal image information is obtained by taking a photo with a camera.

[0216] Step 50234: select the abnormal object features according to the abnormal image information, control the preset robotic arm to clamp the abnormal object corresponding to the abnormal object features, and obtain the clamping weight value.

[0217] Abnormal object features refer to features in the image that are not artifacts. Abnormal object features are obtained by eliminating artifact features from abnormal image information. The abnormal object corresponding to the abnormal object features is clamped by controlling the robotic arm, and the clamping weight value is obtained. The clamping weight value is the weight value of the abnormal object corresponding to the abnormal object features clamped by the robotic arm, and the clamping weight value is obtained by the weight sensor on the robotic arm.

[0218] Step 50235: Control the robot arm to clamp the abnormal object to a preset repair area or to clamp the abnormal object to a preset recycling area according to the size relationship between the clamping weight value and the workpiece weight value.

[0219] By judging the magnitude relationship between the clamping weight value and the workpiece weight value, it is possible to know whether the clamped abnormal object is an abnormal object integrated with the workpiece or another abnormal object.

[0220] If the clamping weight value is greater than the workpiece weight value, it means that the clamped abnormal object is an abnormal object integrated with the workpiece. The abnormal object needs to be held to the repair area. The repair area refers to the area used to separate the abnormal object integrated with the workpiece. The repair area is set in advance by a person skilled in the art and will not be described in detail here.

[0221] If the clamping weight value is less than the workpiece weight value, it means that the clamped abnormal object is another abnormal object. Simply clamp the abnormal object to the recycling area.

[0222] The processing when the newly added weight value is zero includes the following steps:

[0223] Step 600: When the newly added weight value is zero, control the preset lifting device to lift the cutting position with a preset lifting force.

[0224] The lifting device refers to a hydraulic push rod used to lift the workpiece that has not fallen after cutting. The lifting force refers to the force when the lifting device lifts the fallen workpiece. The lifting force is set in advance by a person skilled in the art and will not be described in detail here. When the added weight value is zero, the cutting position is lifted by controlling the lifting device with the lifting force.

[0225] Step 601: During lifting, obtain lifting pressure information.

[0226] The lifting pressure information refers to the pressure on the end of the lifting device that contacts the workpiece when the lifting device is lifting. A plurality of pressure sensors are provided on the end of the lifting device that contacts the workpiece, and the lifting pressure information of each area of ​​the end of the lifting device that contacts the workpiece can be obtained through the pressure sensors.

[0227] Step 602: Determine the tilt angle of the workpiece according to the lifting pressure information.

[0228] The tilt angle of the workpiece refers to the angle at which the workpiece tilts after being lifted. A plurality of pressure sensors are provided on the lifting device, and each of them is provided with a corresponding number. The tilt angle of the workpiece can be analyzed from the preset tilt database through the different lifting pressure information corresponding to the numbers of the pressure sensors at the positions of the various areas on one end where the lifting device abuts against the workpiece. The tilt database contains the correspondence between the lifting pressure information and the tilt angle of the workpiece. The tilt database is a manually set database and will not be described in detail here.

[0229] Step 603: Determine whether the workpiece inclination angle is greater than a preset reference inclination angle.

[0230] The reference tilt angle refers to the angle when the workpiece is not tilted, that is, the reference tilt angle is zero. The reference tilt angle is set in advance by a person skilled in the art and will not be described in detail here. By judging whether the tilt angle of the workpiece is greater than the reference tilt angle, the cutting progress of the workpiece can be known.

[0231] Step 6031: If the workpiece inclination angle is not greater than the reference inclination angle, a cutting error signal is output to a preset signal transceiver terminal.

[0232] If the tilt angle of the workpiece is not greater than the reference tilt angle, it means that the lifting device cannot lift the workpiece, which means that the cutting device has hardly cut the current workpiece. A cutting error signal needs to be output to the preset signal transceiver terminal. The cutting error signal refers to the signal sent when the cutting device has hardly cut the current workpiece. The signal transceiver terminal is used to receive and send various signals for subsequent work.

[0233] Step 6032: If the inclination angle of the workpiece is greater than the reference inclination angle, the remaining cutting starting point and the remaining cutting margin are determined according to the inclination angle of the workpiece.

[0234] If the tilt angle of the workpiece is greater than the reference tilt angle, it means that the lifting device can lift the workpiece, which means that the cutting device has not completely cut the current workpiece and there are some parts that have not been cut. The part that has been cut can be known through the tilt angle of the workpiece, and then the remaining cutting starting point and the remaining cutting margin can be known.

[0235] Step 6033: According to the remaining cutting starting point and the remaining cutting margin, the preset auxiliary cutting equipment is controlled to move to the remaining cutting starting point for cutting.

[0236] The auxiliary cutting device refers to a spare laser cutting machine installed on the cutting device for re-cutting the incompletely cut workpiece. The auxiliary cutting device is clamped and moved to the remaining cutting starting point by a mechanical arm to cut the remaining cutting margin of the workpiece.

[0237] The heat dissipation method includes the following steps:

[0238] Step 700: After the heat dissipation device is started, a heat conduction baffle preset in the heat dissipation device is controlled to extend toward the plate until it contacts the plate.

[0239] When the heat dissipation device is started, the heat conduction baffle in the heat dissipation device is controlled to extend in the direction of the plate at a preset extension distance to complete the contact with the plate. The heat conduction baffle refers to a baffle used to guide the heat on the plate into the heat dissipation device for heat dissipation. The extension distance refers to the distance that the heat baffle extends in the direction of the plate. The extension distance is set in advance by a person skilled in the art and will not be described in detail here.

[0240] Step 701: After the extension is completed, obtain device temperature information of the heat dissipation device.

[0241] The device temperature information refers to the temperature of the heat dissipation device itself. The device temperature information is measured and obtained by an infrared temperature measuring gun.

[0242] Step 702: Match the blowing speed from a preset heat dissipation database according to the device temperature information.

[0243] The blowing speed refers to the speed at which the preset blower blows air to the air inlet of the heat dissipation device. The blowing speed corresponding to the device temperature information can be matched through the heat dissipation database. The heat dissipation database is a manually set database and will not be described in detail here.

[0244] Step 703: Control a preset blowing device to inflate and blow air to the air inlet of the heat dissipation device according to the blowing speed.

[0245] The blowing device refers to a blower used to inflate and blow air to the air inlet of the heat sink. The blowing device is controlled to inflate and blow air to the air inlet of the heat sink at a blowing speed to reduce the temperature of the heat sink.

[0246] Step 704: When blowing air based on inflation, obtain ambient temperature information of the heat dissipation device and air outlet temperature information of the air outlet on the heat dissipation device.

[0247] The ambient temperature information refers to the temperature around the heat sink. The air outlet temperature information refers to the temperature at the air outlet of the heat sink. The ambient temperature information and air outlet temperature information are measured and obtained by using an infrared temperature measuring gun.

[0248] Step 705: Determine the inflation blowing temperature according to the outlet air temperature information.

[0249] The inflation blowing temperature refers to the temperature when the blowing device inflates and blows air to the heat dissipation device. The inflation blowing temperature corresponding to the outlet temperature information can be matched in the preset inflation database. The higher the outlet temperature information, the lower the inflation blowing temperature, and the inflation blowing temperature cannot be lower than the preset minimum temperature. The inflation database is a manually set database and will not be described in detail here.

[0250] Step 706: Control a preset temperature regulating device to adjust the blowing temperature during inflation blowing according to the inflation blowing temperature.

[0251] The temperature regulating device refers to a semiconductor heating plate used to regulate the temperature of the air blown by the blowing device. The temperature regulating device is controlled to regulate the air blown by the blowing device to be consistent with the inflation air temperature.

[0252] Step 707: Match the atomization degree from a preset water mist database according to the ambient temperature information.

[0253] The degree of atomization refers to the power of atomizing water used to cool the air inlet. The degree of atomization corresponding to the ambient temperature information can be matched through the water mist database. The higher the temperature of the ambient temperature information, the higher the degree of atomization.

[0254] Step 708: Control the preset spraying equipment on the blowing device to spray and cool the air inlet according to the degree of atomization.

[0255] The spraying device refers to a humidifier used to spray water. The degree of atomization of the water outlet can be adjusted by adjusting the degree of sealing of the water outlet of the spraying device. Based on the degree of atomization, the spraying device on the blowing device is controlled to spray and cool the air inlet. The water sprayed by the spraying device is blown into the air inlet by the wind blown by the blowing device.

[0256] The protection method of parts and plates includes the following steps:

[0257] Step 800: After the heat dissipation device is started, the difference between the ambient temperature information and the preset reference temperature information is calculated and defined as a cooling temperature value.

[0258] When the heat dissipation device is started, the cooling temperature value needs to be calculated. The cooling temperature value can be obtained by subtracting the temperature value of the reference temperature information from the temperature value of the ambient temperature information. The cooling temperature value refers to the temperature value that the plate needs to be lowered. The reference temperature information refers to the temperature value that the plate needs to reach.

[0259] Step 801: Match the restored wind force value from the preset blowing database according to the cooling temperature value.

[0260] The restored wind force value refers to the wind force of the hair dryer when the temperature of the ambient temperature information is reduced to the temperature of the reference temperature information. The restored wind force value corresponding to the cooling temperature value can be matched through the blowing database. The blowing database is a manually set database and will not be described in detail here.

[0261] Step 802: Determine reducing gas according to material information.

[0262] Reducing gas refers to the gas used to reduce the oxidation rate of plates and parts. The reducing gas corresponding to the material information can be matched through the preset reduction database. The reducing gas corresponding to plates of different materials is different. The reduction database is a manually set database and will not be described in detail here.

[0263] Step 803: Match the gas release amount from a preset gas database according to the material information and the reducing gas.

[0264] The gas release volume refers to the total volume of the reducing gas blown out. The gas database can be used to match the material information and the corresponding gas release volume of the reducing gas. The gas database contains the corresponding relationship between the material information, reducing gas and the gas release volume. The gas database is a manually set database and will not be described here.

[0265] Step 804: Determine the blowing position according to the cutting position.

[0266] The blowing position refers to the position where the hair dryer blows air to the plate. Since the reducing gas blown out is to reduce the oxidation rate of the plate and the workpiece, the cutting position needs to be blown, and then the cutting position is the blowing position.

[0267] Step 805: Control the blower to blow air to the blowing position according to the restored wind force value, the restored gas, and the gas release amount.

[0268] The blower is controlled to blow air to the blowing position according to the obtained reducing wind force value, reducing gas and gas release amount, so as to reduce the oxidation rate of the plate and the workpiece.
