Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, and in particular to a method, device, equipment, medium and cutting system for processing a washing machine barrel body. Background Art

[0002] During the production of a washing machine drum, knurling needs to be performed on a blank. Affected by the knurling structure, the shrinkage amounts at the middle knurled position and the non-knurled side position are inconsistent after curling, resulting in gaps at the splicing joints when the blanks are welded and spliced later. Only lapping and then riveting connections can be used, but the strength of the riveted joints is low and it is easy to accumulate dirt, resulting in low quality of the produced washing machine drums.

[0063] The realization, functional characteristics and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0064] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0065] Referring to Figure 1 , Figure 1 It is a schematic structural diagram of the washing machine barrel processing equipment for the hardware operating environment involved in the embodiment solution of the present invention.

[0066] As Figure 1 shown, the washing machine barrel processing equipment may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless-fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM), or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0067] Those skilled in the art can understand that Figure 1 the structure shown in

[0068] As Figure 1As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a washing machine barrel body processing program.

[0069] In Figure 1 In the washing machine barrel body processing equipment shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the washing machine barrel body processing equipment of the present invention may be arranged in the washing machine barrel body processing equipment. The washing machine barrel body processing equipment calls the washing machine barrel body processing program stored in the memory 1005 through the processor 1001 and executes the washing machine barrel body processing method provided by the embodiment of the present invention.

[0070] The embodiment of the present invention provides a washing machine barrel body processing method. Refer to Figure 2 , Figure 2 It is a schematic flowchart of the first embodiment of a washing machine barrel body processing method of the present invention.

[0071] In this embodiment, the washing machine barrel body processing method is applied to a washing machine barrel body cutting system. The washing machine barrel body cutting system includes a positioning mechanism and a laser cutting head. The washing machine barrel body processing method includes the following steps:

[0072] Step S10: Perform knurling on the original blank to obtain a to-be-processed blank.

[0073] It should be noted that the above washing machine barrel body cutting system may be a laser cutting system. In this embodiment, laser cutting is adopted to replace die punching, so as to realize the compensation and correction of the cutting trajectory. Compared with the cutting means of using die punching in the prior art, in this embodiment, flexible trajectory correction and dynamic adjustment of the laser cutting trajectory can be realized through laser cutting, thereby improving the cutting accuracy and cutting efficiency of the blank, improving the quality of the finished washing machine drum, and adopting laser cutting to avoid the die loss in the traditional process, greatly reducing the production cost. The laser cutting end face is flat and free of burrs, avoiding the problem of poor cutting end face caused by the passivation of the punching die, thereby improving the welding quality.

[0074] It should be understood that the execution subject of the method in this embodiment may be a washing machine barrel body processing equipment with data processing, network communication, and program running functions, such as a numerical control machine tool, a computer, etc., or other devices or equipment that can achieve the same or similar functions. Here, the above washing machine barrel body processing equipment (hereinafter referred to as the processing equipment) is taken as an example for description.

[0075] It should be noted that the knurling process can be planar knurling. By stretching out a designed shape on the blank, it is used to increase the friction of the inner cylinder during laundry. The blank to be processed can be the sheet metal to be processed for the washing machine barrel body.

[0076] It can be understood that the processing equipment first divides the coiled material to be processed for the washing machine barrel body into single sheet metal (i.e., obtaining the blank to be processed), and then performs knurling on the blank to be processed, stretching out a designed shape on the blank, which is used to increase the friction of the inner cylinder during laundry.

[0077] Furthermore, in order to effectively eliminate the defects at both side edges of the blank, the above step S10 may include:

[0078] Step S11: Perform knurling on the original blank;

[0079] Step S12: Determine the areas to be trimmed on both sides of the original blank after knurling;

[0080] Step S13: Use the laser cutting head to perform laser cutting on the areas to be trimmed to obtain the blank to be processed.

[0081] It should be noted that the areas to be trimmed can be areas with a preset size on both side edges of the original blank after knurling. For example, laser trimming and cutting are performed on a width of 2 - 3 mm on both side edges of the original blank.

[0082] It can be understood that the original blank can be a single sheet metal divided from the coiled material. After cutting and dividing, there may be defects such as burrs and notches at both side edges of the original blank. In order to eliminate the defects at the edges and improve the quality of the blank, the processing equipment uses laser cutting to perform straight edge trimming on the knurled blank.

[0083] Step S20: Generate a cutting trajectory based on the blank to be processed.

[0084] It should be noted that the cutting trajectory can be the cutting trajectory for cutting both side edges of the blank to be processed, that is, the laser cutting trajectory. The processing equipment can perform cutting on the blank to be processed through the laser cutting head based on the cutting trajectory.

[0085] It can be understood that there are uneven edges and / or burrs at both side edges of the blank to be processed. Therefore, it is necessary to cut both sides of the blank to be processed along the cutting trajectory through the laser cutting head to improve the splicing quality of the blank to be processed.

[0086] It should be understood that the processing equipment can generate a cutting trajectory based on the preset splicing requirements and / or the edge contour of the blank to be processed. For example, the knurled blank to be processed is subjected to straight edge trimming by laser cutting, cutting about 2 mm.

[0087] Step S30: Position the to-be-processed sheet through a positioning mechanism.

[0088] It should be noted that the washing machine barrel cutting system may include an A cutting station, a B cutting station, an XYZ three-axis motion slide, a front-end in-place positioning mechanism, a pressing mechanism, an anti-warping edge mechanism, and a laser welding head. The working steps are as follows:

[0089] 1) The A and B cutting stations move towards both ends respectively. The sheet is placed at the preset positioning position on the positioning roller table through a mechanical loading gripper, and the positioning mechanisms on both sides of the roller table clamp to perform lateral positioning on the sheet.

[0090] 2) The A and B cutting stations move towards the middle to the pre-pressing position, and the anti-warping edge mechanism descends to pre-press the sheet to prevent the sheet from warping and hitting the positioning mechanism, resulting in damage to the sheet.

[0091] 3) The A and B cutting stations continue to move towards the middle, and the front-end in-place positioning mechanism performs longitudinal positioning on the sheet. After positioning, the pressing mechanism descends to press both ends of the sheet.

[0092] 4) The three-axis motion slide drives the cutting head to cut the sheet according to a predetermined trajectory. After completion, the cutting head resets.

[0093] 5) After processing is completed, the pressing mechanism and the anti-warping edge mechanism rise. The A and B cutting stations move towards both ends respectively, the positioning mechanisms on the roller table side are loosened, and the robot unloads the material.

[0094] Step S40: Based on the cutting trajectory, perform laser cutting on the positioned to-be-processed sheet through the laser cutting head.

[0095] It should be noted that the processing equipment controls the laser cutting head to cut the to-be-processed sheet along the cutting trajectory.

[0096] In a specific implementation, the processing equipment can drive the laser cutting head to perform laser cutting on the to-be-processed sheet along the cutting trajectory through a three-axis motion module, thereby realizing three-axis cutting to achieve high-precision multi-directional cutting.

[0097] Step S50: Perform curling processing on the cut to-be-processed sheet to obtain a washing machine barrel.

[0098] In a specific implementation, the processing equipment imports the cutting trajectory into the washing machine barrel cutting system, and the washing machine barrel cutting system performs laser cutting on the edge positions on both sides of the to-be-processed sheet, and curls and joins the cut sheet to obtain a washing machine barrel.

[0099] It should be noted that the processing equipment cuts both sides of the to-be-processed sheet based on the cutting trajectory. In some embodiments, the processing equipment can compensate the cutting trajectory to generate a more accurate trajectory, and perform laser cutting on the positions of the to-be-processed sheet that need to be cut based on the compensated trajectory, and then roll and splice the cut sheet to obtain the washing machine barrel body.

[0100] In a specific implementation, the processing equipment imports the cutting trajectory into the washing machine barrel body cutting system, and the washing machine barrel body cutting system performs laser cutting on the positions to be cut on both sides of the to-be-processed sheet along the cutting trajectory, and then rolls and splices the cut sheet to obtain the washing machine barrel body.

[0101] It can be understood that referring to Figure 3 , Figure 3 is a splicing schematic diagram of the to-be-processed sheet without cutting compensation. It can be clearly seen that there are gaps at the splicing positions, and the parameters Figure 4 , Figure 4 is a splicing schematic diagram of the to-be-processed sheet after cutting compensation. In this embodiment, by performing cutting compensation on both sides of the to-be-processed sheet, the gaps generated by the rolling and splicing of the sheet are effectively eliminated, and the splicing quality is improved.

[0102] Further, in order to improve the processing efficiency of the washing machine barrel body, after the above step S50, the following steps may be included:

[0103] Detect whether there is a gap in the splicing area of the washing machine barrel body;

[0104] If there is no gap, save the cutting trajectory, and perform laser cutting on other sheets of the same batch as the to-be-processed sheet based on the cutting trajectory;

[0105] If there is a gap, return to the step of generating the cutting trajectory based on the to-be-processed sheet until there is no gap in the splicing area of the washing machine barrel body.

[0106] It should be noted that the processing equipment can collect images of the splicing area of the washing machine barrel body, obtain the splicing state of the splicing area based on the splicing area image, judge whether there is a splicing gap in the washing machine barrel body based on the splicing state. If there is a gap, adjust and correct the compensation trajectory, and continue to perform cutting compensation on the to-be-processed sheet until there is no gap in the splicing area of the washing machine barrel body; if there is no gap, save the cutting trajectory, import the compensated trajectory into the laser cutting system, and perform cutting compensation on the sheets of the same batch as the to-be-processed sheet based on the saved cutting trajectory.

[0107] In this embodiment, the raw sheet is knurled to obtain the sheet to be processed, a cutting trajectory is generated based on the sheet to be processed, the sheet to be processed is positioned by a positioning mechanism, and the positioned sheet to be processed is laser cut by the laser cutting head based on the cutting trajectory, so as to achieve precise cutting of the sheet material. The processed sheet to be processed is subjected to curling processing to obtain the washing machine barrel body, thereby meeting the automated high-precision welding requirements of the washing machine drum, reducing the transformation cost of the existing production line, effectively improving the splicing quality of the washing machine barrel body, and significantly enhancing the barrel body strength.

[0108] Reference Figure 5 , Figure 5 is a schematic flowchart of the second embodiment of a method for processing a washing machine barrel body according to the present invention.

[0109] Based on the above first embodiment, in this embodiment, the step S20 includes:

[0110] Step S21: Identify the edges to be welded on the knurled edge of the sheet to be processed.

[0111] It should be noted that the edges to be welded can be the edges on both sides of the sheet to be processed that need to be welded and spliced. In this embodiment, the edges to be welded of the sheet to be processed can be visually inspected and imaged to obtain the expansion and contraction amount information on both sides of the sheet to be processed.

[0112] Step S22: Obtain the expansion and contraction amount information of the edges to be welded according to the recognition result.

[0113] It can be understood that after the sheet is curled, the expansion and contraction amounts at the knurled position in the middle and the non-knurled position next to it are inconsistent, resulting in too large a gap at the splicing position. In this embodiment, by obtaining the expansion and contraction amount information of the edges to be welded, a cutting trajectory is generated based on the expansion and contraction amount information, and laser cutting is performed based on the expansion and contraction information, effectively eliminating the gap at the splicing position and improving the splicing quality of the sheet material.

[0114] Step S23: Generate a cutting trajectory based on the expansion and contraction amount information.

[0115] It can be understood that in this embodiment, the sheet to be processed can be cut based on the expansion and contraction information to avoid the problem of too large a splicing gap caused by inconsistent expansion and contraction amounts on both sides of the sheet. Compared with direct cutting, in this embodiment, cutting can be performed based on the expansion and contraction amount information, thereby effectively eliminating the burrs, irregularities, and uneven parts on both sides, and improving the splicing quality.

[0116] Further, in order to effectively eliminate the splicing gap, the above step S23 may include:

[0117] Step S231: Obtain the washing machine processing requirement information;

[0118] Step S232: Generate an original trajectory based on the washing machine processing requirement information;

[0119] Step S233: Generate the edge profile of the edge to be welded according to the telescopic amount information;

[0120] Step S234: Compensate the original trajectory based on the edge profile to obtain a cutting trajectory.

[0121] It should be noted that the washing machine processing requirement information can be the processing requirement information of the washing machine barrel blank. For example, the washing machine processing requirement information may include the blank size of the washing machine barrel, the edge cutting size, etc. The above original trajectory can be a trajectory for directly performing straight-line cutting on both sides of the to-be-processed blank according to the target cutting size in the washing machine processing requirement information.

[0122] It can be understood that the above edge profile can be the edge profiles to be welded on both sides of the to-be-processed blank. In this embodiment, the edge profiles on both sides of the to-be-processed blank can be generated by performing visual inspection and image acquisition on the to-be-processed blank and combining the telescopic amount information of the blank.

[0123] It should be noted that in this embodiment, the original trajectory can be compensated based on the edge profile to generate a compensated cutting trajectory (i.e., a cutting compensation trajectory). The above cutting compensation trajectory can be a laser cutting trajectory that needs to be compensated and corrected on both sides of the to-be-processed blank.

[0124] It should be understood that the processing equipment can perform cutting compensation on the edges of the to-be-processed blank based on the cutting compensation trajectory, thereby effectively avoiding the generation of gaps when splicing the edges on both sides of the to-be-processed blank.

[0125] It can be understood that the processing equipment in this embodiment can generate an edge profile based on the edge parameters by acquiring the edge parameters on both sides of the to-be-processed blank, perform edge compensation based on the edge profile, and generate a cutting compensation trajectory to eliminate the gaps generated during edge splicing.

[0126] It should be noted that after the to-be-processed blank is curled, the telescopic amounts at the middle knurled position and the non-knurled position beside it are inconsistent, resulting in too large a gap at the splicing position. Only lapping and then riveting connection can be used. The riveting interface has lower strength than the laser welding interface and is prone to dirt accumulation. Therefore, it is necessary to compensate the original trajectory according to the telescopic amount information of the to-be-processed blank to ensure that there are no gaps when splicing the edges on both sides of the to-be-processed blank.

[0127] It should be understood that the equipment in this embodiment can determine the positions to be welded on both sides of the to-be-processed blank, perform data acquisition on the edges to be welded on both sides of the to-be-processed blank based on the positions to be welded, obtain the edge parameters on both sides of the to-be-processed blank, and extract the edge profile of the to-be-processed blank based on the edge parameters to obtain the edge profile.

[0128] In a specific implementation, the processing device can acquire an image of the edge contour of the to-be-processed wafer to obtain the contour parameters of the to-be-processed wafer, or measure the edge of the to-be-processed wafer with a vernier caliper to obtain the contour parameters, and obtain the edge contour of the to-be-processed wafer based on the contour parameters.

[0129] Further, in order to accurately generate the contour of the to-be-welded edge, the above step S233 may include:

[0130] Step S2331: Perform a curling and splicing test on the to-be-processed wafer.

[0131] It should be noted that the curling and splicing test can be performed by curling the to-be-processed wafer into a barrel shape to test the curling result of the wafers of the same batch as the to-be-processed wafer, and determining the edge splicing state after curling and splicing the two side edges of the wafers of the same batch as the to-be-processed wafer based on the curling result, so as to determine whether there is a gap after the wafer is curled and spliced.

[0132] In some embodiments, the processing device can acquire the wafer material parameters (such as density, material stiffness, material elasticity parameters, etc.), wafer size parameters, and wafer edge parameters of the to-be-processed wafer, construct a simulation model of the to-be-processed wafer based on the wafer material parameters, wafer size parameters, and wafer edge parameters, perform curling simulation based on the simulation model, and obtain the edge splicing state of the to-be-processed wafer based on the curling simulation result.

[0133] Step S2332: Obtain the edge splicing state of the to-be-processed wafer based on the curling and splicing test result.

[0134] It should be noted that the edge splicing state can be the splicing state of the two side edges of the wafer after the to-be-processed wafer is curled.

[0135] It can be understood that the processing device can judge whether there is a gap, the gap size, the gap position, etc. after the to-be-processed wafer is curled and spliced based on the curling and splicing test result.

[0136] Step S2333: Obtain the splicing contour information of the to-be-processed wafer according to the edge splicing state.

[0137] It should be noted that the splicing contour information can be the contour data of the two side edges that are spliced with each other after the to-be-processed wafer is curled, such as the shape and size of the void part at the splicing position, etc.

[0138] It can be understood that the processing equipment can judge whether there is a splicing gap after splicing the to-be-processed wafers based on the edge splicing state. If not, the to-be-processed wafers and the wafers of the same batch as the to-be-processed wafers are spliced and welded. If there is a splicing gap, parameters such as the shape and size of the splicing gap of the to-be-processed wafer are obtained to obtain the splicing contour information of the to-be-processed wafer.

[0139] Step S2334: Generate an edge contour based on the splicing contour information and the telescopic amount information.

[0140] It should be noted that the processing equipment can obtain the contour data of the splicing part of the two sides of the wafer through measurement or image processing technology, including the splicing contour information such as the shape and size of the gap part. Based on the splicing contour information, contour fitting is performed to generate the edge contour at the edge gap position.

[0141] Furthermore, in order to accurately generate the cutting compensation trajectory, the above step S234 may include:

[0142] Step S2341: Perform reverse fitting based on the edge contour to generate a reverse fitting contour;

[0143] Step S2342: Perform trajectory simulation according to the reverse fitting contour;

[0144] Step S2343: Compensate the original trajectory based on the trajectory simulation result to obtain the cutting trajectory.

[0145] It should be noted that the processing equipment can obtain the contour data of the splicing part of the two sides of the wafer through measurement or image processing technology, including the shape and size of the gap part. This will become the basic data for reverse fitting. Create a contour opposite to it based on the edge contour data, that is, compensate the gap part. The reverse fitting contour should take into account the bending properties of the material and possible deformation factors during the welding process.

[0146] In some embodiments, once the processing equipment creates a reverse fitting contour, some fine-tuning and optimization may be required to ensure that it perfectly matches the edge contour, thereby eliminating the gap. Therefore, the processing equipment can perform correction processing on the initially generated reverse fitting contour to obtain an accurate reverse fitting contour.

[0147] It can be understood that the processing equipment performs trajectory simulation based on the reverse-fitted profile and uses the reverse-fitted profile data to create a compensation trajectory. This compensation trajectory will be based on the reverse-fitted profile to ensure that the cutting process can compensate for the gaps and achieve the required shape and size. When creating the compensation trajectory, cutting parameters such as cutting speed, tool type, tool diameter, etc. can be set. These parameters may affect the cutting accuracy and efficiency and need to be adjusted according to specific material and process requirements.

[0148] In this embodiment, by identifying the weld edges of the to-be-processed workpiece after knurling, obtaining the expansion amount information of the weld edges according to the identification result, and generating a cutting trajectory based on the expansion amount information, the problem that there are gaps in the splicing of the to-be-processed workpiece due to inconsistent expansion amounts on both sides is effectively solved, thereby effectively eliminating the gaps generated by the splicing of the workpiece and improving the splicing quality.

[0149] In addition, an embodiment of the present invention further provides a washing machine barrel cutting system, refer to Figure 6 , Figure 6 which is a schematic structural diagram of the washing machine barrel cutting system in the present invention.

[0150] In this embodiment, the washing machine barrel cutting system includes: a laser cutting mechanism and a positioning mechanism. The laser cutting mechanism includes a first cutting unit and a second cutting unit, and the first cutting unit and the second cutting unit are respectively arranged on both sides of the positioning mechanism;

[0151] The positioning mechanism is used to position the to-be-processed workpiece;

[0152] The first cutting unit and the second cutting unit are respectively used to perform laser cutting on both sides of the positioned to-be-processed workpiece.

[0153] It should be noted that the first cutting unit can be arranged on one side of the positioning mechanism, and the second cutting unit can be arranged on the other side of the positioning mechanism. The above positioning structure can be a side positioning roller table. In this embodiment, the first cutting unit can be an A cutting station, and the second cutting unit can be a B cutting station. The above positioning mechanism is arranged in the middle of the A cutting station and the B cutting station. Among them, the cutting stations on both sides of the positioning mechanism can move back and forth through the slide rails. When moving towards both ends respectively, there is sufficient space for loading the sheet material. When moving towards the middle together, the positioning and cutting of the sheet material can be realized.

[0154] In specific implementation, the washing machine barrel cutting system can place the to-be-processed workpiece at the preset position of the positioning mechanism through a mechanical loading gripper. The positioning structure can clamp and position the to-be-processed workpiece, and the first cutting unit and the second cutting unit can respectively perform laser cutting on both sides of the to-be-processed workpiece on the positioning mechanism.

[0155] Furthermore, in order to improve the cutting accuracy and efficiency, refer to Figure 7 , Figure 7 which is a schematic structural diagram of the laser cutting mechanism in this embodiment. The laser cutting mechanism includes a three-axis motion module and a laser cutting head, and the laser cutting head is connected to the three-axis motion module;

[0156] The laser cutting head is used to perform laser cutting on the to-be-processed wafer;

[0157] The three-axis motion module is used to drive the laser cutting head to perform three-axis movement.

[0158] It should be noted that the laser cutting mechanism includes a three-axis motion module and a laser cutting head. The above three-axis motion module can be an XYZ three-axis motion stage, and the laser cutting head can move along the X-axis, Y-axis, and Z-axis respectively through the three-axis motion module, so as to move to any position to perform laser cutting on the to-be-processed wafer. The three-axis motion module includes an X-axis motion unit, a Y-axis motion unit, and a Z-axis motion unit.

[0159] In some embodiments, refer to Figure 8 , Figure 8 which is a side view of the laser cutting mechanism. The laser cutting mechanism can be composed of a three-axis motion module, a front-end in-place positioning mechanism, a pressing mechanism, an anti-warping-edge mechanism, and a laser cutting head. The working steps are as follows:

[0160] 1. The first cutting unit and the second cutting unit move towards both ends of the positioning mechanism respectively, and the to-be-processed wafer is placed at the preset position of the positioning mechanism through the mechanical loading gripper. The positioning mechanism clamps both sides of the to-be-processed wafer to perform lateral positioning on the to-be-processed wafer;

[0161] 2. The first cutting unit and the second cutting unit move towards the middle to the pre-pressing position, and the anti-warping-edge mechanism descends to pre-press the to-be-processed wafer to prevent the to-be-processed wafer from warping and hitting the positioning mechanism, resulting in damage to the to-be-processed wafer;

[0162] 3. The first cutting unit and the second cutting unit continue to move towards the middle, and the front-end in-place positioning mechanism performs longitudinal positioning on the to-be-processed wafer. After positioning, the pressing mechanism descends to press both ends of the to-be-processed wafer;

[0163] 4. The three-axis motion module drives the laser cutting head to cut the to-be-processed wafer according to a predetermined trajectory (such as a cutting compensation trajectory), and after completion, the cutting head returns to its original position;

[0164] 5. After processing is completed, the pressing mechanism and the anti-warping-edge mechanism rise, the first cutting unit and the second cutting unit move towards both ends respectively, the positioning mechanism is released, and the robot unloads the material.

[0165] In a specific implementation, the washing machine barrel cutting system positions and fixes the to-be-processed sheet material through a positioning mechanism, generates the motion trajectory of the three-axis motion module based on the cutting compensation trajectory planning, so as to realize controlling the three-axis motion module to drive the laser cutting head to perform cutting compensation on both side edges of the to-be-processed sheet material based on the cutting compensation trajectory.

[0166] In this embodiment, the to-be-processed sheet material is pressed, fixed and positioned through a positioning structure. The two sides of the positioned to-be-processed sheet material are respectively subjected to laser cutting by a first cutting unit and a second cutting unit. By using laser cutting, the mold loss in the traditional process is avoided, and the production cost is greatly reduced. The laser cutting end face is flat and free of burrs, avoiding the problem of poor cutting end face caused by the passivation of the punching die, thereby improving the welding quality. The laser cutting head is driven by a three-axis motion module, so as to realize flexible adjustment of the cutting trajectory and dynamic laser cutting. The gap caused by the inconsistent shrinkage amount after the knurled inner barrel is curled can be compensated, solving the problem that it is difficult to weld the knurled sheet material and improving the splicing quality of the washing machine drum.

[0167] In addition, an embodiment of the present invention further provides a storage medium, on which a washing machine barrel processing program is stored. When the washing machine barrel processing program is executed by a processor, the steps of the washing machine barrel processing method as described above are realized.

[0168] Since this storage medium adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.

[0169] Refer to Figure 9 , Figure 9 , which is the structural block diagram of the first embodiment of the washing machine barrel processing device of the present invention.

[0170] As Figure 9 shown, the washing machine barrel processing device proposed by the embodiment of the present invention includes:

[0171] A knurling processing module 10, configured to perform knurling processing on the original sheet material to obtain a to-be-processed sheet material;

[0172] A trajectory generation module 20, configured to generate a cutting trajectory based on the to-be-processed sheet material;

[0173] A sheet material positioning module 30, configured to position the to-be-processed sheet material through a positioning mechanism;

[0174] A laser cutting module 40, configured to perform laser cutting on the positioned to-be-processed sheet material through the laser cutting head based on the cutting trajectory;

[0175] The curling processing module 50 is used to perform curling processing on the to-be-processed sheet after cutting to obtain the washing machine barrel body.

[0176] It should be noted that the knurling process can be planar knurling, which stretches out a designed shape on the sheet to increase the friction of the inner barrel during washing. The to-be-processed sheet can be the sheet material to be processed for the washing machine barrel body.

[0177] It can be understood that the processing equipment divides the coiled material of the to-be-processed washing machine barrel body in advance, divides the coiled material into single sheets (i.e., obtains the to-be-processed sheet), and then performs knurling on the to-be-processed sheet to stretch out a designed shape on the sheet to increase the friction of the inner barrel during washing.

[0178] It should be noted that the cutting trajectory can be the cutting trajectory for cutting both sides of the to-be-processed sheet, that is, the laser cutting trajectory. The processing equipment can cut the to-be-processed sheet through the laser cutting head based on the cutting trajectory.

[0179] It can be understood that there are uneven edges and / or burrs at both sides of the to-be-processed sheet. Therefore, it is necessary to cut both sides of the to-be-processed sheet along the cutting trajectory through the laser cutting head to improve the splicing quality of the to-be-processed sheet.

[0180] It should be understood that the processing equipment can generate the cutting trajectory based on the preset splicing requirements and / or the edge contour of the to-be-processed sheet. For example, the to-be-processed sheet after knurling is linearly trimmed by laser cutting, and the cutting is about 2 mm.

[0181] It should be noted that the cutting system of the washing machine barrel body can include an A cutting station, a B cutting station, an XYZ three-axis moving slide, a front-end in-place positioning mechanism, a pressing mechanism, an anti-warping edge mechanism, and a laser welding head. The working steps are as follows:

[0182] 1) The A and B cutting stations move towards both ends respectively. The sheet is placed at the preset positioning position on the positioning roller table through the mechanical loading gripper, and the positioning mechanisms on both sides of the roller table clamp to perform lateral positioning on the sheet.

[0183] 2) The A and B cutting stations move towards the middle to the pre-pressing position, and the anti-warping edge mechanism descends to pre-press the sheet to prevent the sheet from warping and hitting the positioning mechanism, resulting in damage to the sheet.

[0184] 3) The A and B cutting stations continue to move towards the middle, and the front-end in-place positioning mechanism performs longitudinal positioning on the sheet. After positioning, the pressing mechanism descends to press both ends of the sheet.

[0185] 4) The three-axis moving slide drives the cutting head to cut the sheet according to the predetermined trajectory. After completion, the cutting head returns to its original position.

[0186] 5) After processing is completed, the pressing mechanism and the anti-warping edge mechanism rise, the AB cutting stations move towards both ends respectively, the side positioning mechanism of the roller table is released, and the robot unloads the material.

[0187] It should be noted that the processing equipment controls the laser cutting head to cut the to-be-processed workpiece along the cutting trajectory.

[0188] In a specific implementation, the processing equipment can drive the laser cutting head to perform laser cutting on the to-be-processed workpiece along the cutting trajectory through a three-axis motion module, so as to achieve three-axis cutting and realize high-precision multi-directional cutting.

[0189] In a specific implementation, the processing equipment imports the cutting trajectory into the washing machine barrel cutting system, and through the washing machine barrel cutting system, laser cutting is performed on the edge positions on both sides of the to-be-processed workpiece, and the cut workpiece is rolled and spliced to obtain the washing machine barrel.

[0190] It should be noted that the processing equipment cuts both sides of the to-be-processed workpiece based on the cutting trajectory. In some embodiments, the processing equipment can compensate the cutting trajectory to generate a more accurate trajectory, and based on the compensated trajectory, laser cutting is performed on the positions to be cut of the to-be-processed workpiece, and the cut workpiece is rolled and spliced to obtain the washing machine barrel.

[0191] In a specific implementation, the processing equipment imports the cutting compensation trajectory into the washing machine barrel cutting system, and through the washing machine barrel cutting system, laser cutting is performed on the edge positions to be compensated on both sides of the to-be-processed workpiece, and the cut workpiece is rolled and spliced to obtain the washing machine barrel.

[0192] In this embodiment, the raw workpiece is knurled to obtain the to-be-processed workpiece, the cutting trajectory is generated based on the to-be-processed workpiece, the to-be-processed workpiece is positioned by the positioning mechanism, and based on the cutting trajectory, the laser cutting head performs laser cutting on the positioned to-be-processed workpiece to achieve precise cutting of the workpiece plate. Based on the cut to-be-processed workpiece, rolling processing is performed to obtain the washing machine barrel, thereby realizing the automated high-precision welding requirement of the washing machine drum, reducing the transformation cost of the existing production line, effectively improving the splicing quality of the washing machine barrel, and greatly enhancing the strength of the barrel.
