Description

Technical Field

[0001] The present invention relates to the technical field of laser forming, and in particular to a control method and a control device for a laser forming production line. Background Art

[0002] In order to increase the output of existing laser forming production lines, multiple groups of laser equipment are usually operated simultaneously on the laser forming production line. During the operation of the laser equipment, sudden failures may occur (such as accidental power failure of the equipment), making the laser equipment unable to work; the usual treatment method is to shut down the failed laser equipment and remove it from the laser forming production line for maintenance. Since the cause of sudden failure of each laser equipment is not fixed, the time when the laser equipment suddenly fails cannot be predicted in advance, which makes the probability of failure of the laser equipment on the entire laser forming production line greater during operation, resulting in an unstable number of laser equipment working on the laser forming production line, which makes the output of the entire laser forming production line unstable. The existing solution is to increase the maintenance frequency of the laser equipment, but frequent shutdown of the laser equipment and sending it for maintenance reduces the number of laser equipment working on the laser forming production line, which in turn reduces the output of the laser forming production line. Therefore, there is a problem of unstable generation efficiency caused by the uncontrollable failure time of the laser equipment in the prior art, and no effective solution has been proposed. Summary of the invention

[0003] In view of the above problems, the present invention is proposed to provide a control method and a control device for a laser forming production line that overcome the above problems or at least partially solve the above problems, which can solve the problem of unstable production efficiency caused by uncontrollable failure time of laser equipment and achieve the purpose of improving user experience.

[0015] Determine whether the accumulated working time of the longest powered-on device is less than a preset time;

[0016] If not, it is determined that the longest powered-on device is the aging device.

[0017] Optionally, in response to the accumulated working time of the longest powered-on device being less than the preset duration, the number of the longest powered-on devices is obtained, and the number of the longest powered-on devices is added to the optimal working number to correct and obtain a first working number;

[0018] The optimal number of jobs is adjusted according to the first number of jobs.

[0019] Optionally, when the longest powered-on device is the aged device, the number of the aged devices is obtained, and the optimal working number is subtracted from the number of the aged devices to correct and obtain a second working number;

[0020] The optimal job quantity is adjusted according to the second job quantity.

[0021] Optionally, adjusting the optimal number of tasks according to the first number of tasks includes:

[0022] Determining whether the first job quantity is less than the optimal job quantity;

[0023] If yes, when the first work quantity is greater than a preset value, taking the first work quantity as the new optimal work quantity;

[0024] If not, the first work quantity is used as the new optimal work quantity.

[0025] Optionally, adjusting the optimal number of tasks according to the second number of tasks includes:

[0026] Determining whether the second job quantity is less than the optimal job quantity;

[0027] If so, when the second work quantity is greater than a preset value, the second work quantity is used as the new optimal work quantity;

[0028] If not, the second work quantity is used as the new optimal work quantity.

[0029] Optionally, adjusting the actual work quantity according to the optimal work quantity includes:

By removing relatively aged equipment on the laser forming production line, the probability of failure of the laser equipment on the laser forming production line during operation can be made relatively small, making the laser forming production line relatively stable, and thus making the production efficiency of the laser forming production line more stable.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0049] Figure 1FIG. 1 is a schematic flow chart of a control method for a laser forming production line according to an embodiment of the present invention. Figure 1 As shown, an embodiment of the present invention provides a control method for a laser forming production line.

[0050] The laser forming production line includes at least two laser devices, and all laser devices are grid-connected and controlled;

[0051] And, the control method of the laser forming production line includes:

[0052] Step S1: obtaining the actual working quantity and the optimal working quantity of the laser equipment in the laser forming production line, where the actual working quantity is the sum of the number of laser equipment in the turned-on state;

[0053] Step S2: adjusting the actual work quantity according to the optimal work quantity;

[0054] Step S3: adjusting the optimal working quantity according to the aging degree of each laser device in the turned-on state.

[0055] Specifically, the control method of the laser forming production line can be executed once a day, once a week, or once a month.

[0056] Each time the above control method is executed, the number of laser devices turned on in the laser forming production line is first obtained as the actual working number; then the optimal working number set by the user according to the production demand is obtained, and the value of the above optimal working number is the initial value.

[0057] After obtaining the actual work quantity and the optimal work quantity, the actual work quantity is adjusted according to the optimal work quantity, that is, the number of laser devices in the turned-on state on the laser forming production line is made close to the optimal work quantity to maximize the output of the laser forming production line.

[0058] After adjusting the actual working quantity, the aging degree of each laser equipment on the laser forming production line is analyzed, and the optimal working quantity is adjusted according to the aging degree of each laser equipment. This allows the laser forming production line to take the equipment with a higher degree of aging offline to ensure as much as possible that the laser forming equipment does not fail when the laser forming production line is working, keep the number of laser equipment in the laser forming production line stable, and thus ensure the stability of the output of the laser forming production line.

[0059] The above control method is based on the common sense that "the higher the aging degree of the equipment, the higher the frequency of equipment failure". It uses the working time of the laser equipment to quantify and reflect the aging degree of the laser equipment, so that the time when the laser equipment fails during operation can be measured and reflected as much as possible through digital measurement, thereby making the time when the laser equipment fails more controllable, which means that sudden failures of the laser equipment can be predicted and prevented to the greatest extent, making the production efficiency of the laser forming production line more stable.

[0060] In some embodiments of the present invention, the control method of the present invention is mainly applied to a laser forming production line, wherein the laser forming process used is one of the 3D additive manufacturing processes, and the laser forming in the present invention mainly refers to stereolithography (SLA), digital light processing (DLP), and direct metal laser sintering (DMLS).

[0061] The laser forming production line in the present invention is preferably a laser forming production line based on a CNC system, wherein the laser equipment is specifically a laser forming equipment.

[0062] In some embodiments of the present invention, adjusting the optimal working quantity according to the aging degree of each laser device in the turned-on state includes:

[0063] Determine whether there is an aging device among the laser devices in the turned-on state;

[0064] If so, reduce the optimal operating quantity based on the amount of aged equipment; or

[0065] If not, increase the optimal number of jobs based on the adjusted actual number of jobs.

[0066] Specifically, determining whether there is an aged device among the laser devices in the turned-on state may also be determining whether the laser devices in the turned-on state are aged devices.

[0067] If there are aging devices, the optimal working quantity is reduced according to the number of aging devices to obtain a new optimal working quantity; when the above control method is executed next time, it is executed according to the above new optimal working quantity, that is, the actual working quantity is adjusted according to the new optimal working quantity, so that the aging equipment in the laser forming production line is taken offline from the laser forming production line, thereby reducing the probability of sudden failure of the laser equipment in the laser forming production line during operation and stabilizing the production efficiency of the laser forming production line.

[0068] Alternatively, if there is no aging equipment, the optimal working quantity is increased according to the adjusted actual working quantity to obtain a new optimal working quantity; it should be noted that the above new optimal working quantity is greater than the actual working quantity; when the above control method is executed next time, it is executed according to the above new optimal working quantity, and the actual working quantity is adjusted according to the optimal working quantity. In other words, more laser equipment is put online to increase the production capacity of the laser forming production line.

[0069] The embodiment of the present invention uses the aging degree of the equipment as a benchmark for correcting the optimal working quantity. Based on the common sense that "the higher the aging degree of the laser equipment, the higher the frequency of its failure", the higher the aging degree of the laser equipment, the higher the frequency of its failure, and the greater the possibility of failure during the working hours. Based on this, the timing of failure of the aged equipment is relatively controllable compared to other laser equipment. Therefore, after discovering that there is an aged equipment in the laser equipment, by removing the aged equipment from the laser forming production line, the probability of laser equipment failure during operation of the laser forming production line can be greatly reduced, thereby stabilizing the output of the laser forming production line.

[0070] In some alternative embodiments of the present invention, after it is found that there is an aging device on the laser forming production line, the aging device is shut down and taken offline from the laser forming production line when the above control method is executed next time.

[0071] In some embodiments of the present invention, determining whether there is an aged device among the laser devices in the turned-on state includes:

[0072] Obtain the laser device with the longest cumulative working time among all laser devices in the turned-on state, and record it as the longest-on device;

[0073] Determine whether the accumulated working time of the longest powered-on device is less than the preset time;

[0074] If not, the device with the longest power-on time is determined to be an aging device.

[0075] Specifically, the preset duration is preferably 12 months. When executing the above control method, the cumulative working time of each laser device is counted, and the laser device with the longest cumulative working time is counted and recorded as the longest powered-on device. According to the cumulative working time of the longest powered-on device, it is determined whether the longest powered-on device is an aging device.

[0076] The embodiment of the present invention utilizes the working time of the laser device to determine whether there is an aged device in the laser device. That is, the accumulated working time of the laser device is utilized to quantify and reflect the degree of aging of the laser device. This makes the control method more reasonable and accurate in determining the degree of aging and aged devices.

[0077] In some embodiments of the present invention, in response to the cumulative working time of the longest boot device being less than a preset duration, the number of the longest boot devices is obtained, and the number of the longest boot devices is added to the optimal working number to correct the first working number; based on the first working number, the optimal working number is adjusted.

[0078] In some embodiments of the present invention, when the longest powered-on device is an aging device, the number of aging devices is obtained, and the optimal working number is subtracted from the number of aging devices to correct and obtain a second working number;

[0079] The optimal work quantity is adjusted according to the second work quantity.

[0080] In some embodiments of the present invention, adjusting the optimal working quantity according to the first working quantity includes: determining whether the first working quantity is less than the optimal working quantity; if so, when the first working quantity is greater than a preset value, using the first working quantity as the new optimal working quantity; if not, using the first working quantity as the new optimal working quantity.

[0081] Specifically, the preset value is preferably 1, and the preset value may also be the number of laser devices required to maintain the minimum output of the laser forming production line.

[0082] Determining whether the first work quantity is less than the optimal work quantity is to determine whether the first work quantity is less than the initial optimal work quantity;

[0083] In the case where the first work quantity is greater than the initial optimal work quantity, the first work quantity can be directly used as the new optimal work quantity, and the next execution of the control method is performed according to the new optimal work quantity;

[0084] In the case where the first working quantity is less than the initial optimal working quantity, if the first optimal working quantity is greater than a preset value, the first working quantity can be directly used as a new optimal working quantity, and the control method is executed according to the new optimal working quantity in the next execution;

[0085] If the first optimal working quantity is less than or equal to the preset value, all the spare laser devices in the laser forming production line are turned on to strive to maintain the minimum output of the laser forming production line.

[0086] Adjusting the optimal working quantity according to the second working quantity includes: determining whether the second working quantity is less than the optimal working quantity; if so, taking the second working quantity as the new optimal working quantity when the second working quantity is greater than a preset value; if not, taking the second working quantity as the new optimal working quantity.

[0087] Specifically, the preset value is preferably 1, and the preset value may also be the number of laser devices required to maintain the minimum output of the laser forming production line.

[0088] Determining whether the second work quantity is less than the optimal work quantity is to determine whether the second work quantity is less than the initial optimal work quantity;

[0089] In the case where the second work quantity is greater than the initial optimal work quantity, the second work quantity can be directly used as the new optimal work quantity, and in the execution of the next secondary control method, it is executed according to the new optimal work quantity;

[0090] In the case where the second working quantity is less than the initial optimal working quantity, if the second optimal working quantity is greater than a preset value, the second working quantity can be directly used as a new optimal working quantity, and in the execution of the next secondary control method, it is executed according to the new optimal working quantity;

[0091] If the second optimal working quantity is less than or equal to the preset value, all the spare laser devices in the laser forming production line are turned on to strive to maintain the minimum output of the laser forming production line. It should be noted that the above spare laser devices are offline laser devices in the laser forming production line. When the laser device fails unexpectedly and is offline for maintenance, it is marked as a spare laser device.

[0092] The control method of the embodiment of the present invention can prevent the optimal working quantity from being continuously reduced so that the laser forming production line cannot maintain its minimum output. In addition, the control method of the embodiment of the present invention can realize the automatic startup of the backup laser equipment without the need for manual startup after the laser equipment is offline.

[0093] In some embodiments of the present invention, adjusting the actual work quantity according to the optimal work quantity includes:

[0094] Determine whether the actual work quantity is less than the optimal work quantity;

[0095] If so, the backup laser device is turned on according to the difference between the actual working quantity and the optimal working quantity.

[0096] The control method of the embodiment of the present invention can make up the gap between the actual working quantity and the optimal working quantity by turning on the backup laser equipment, so that the actual working quantity approaches or even equals the optimal working quantity, so as to ensure the stability of the production volume of the laser forming production line.

[0097] like Figure 2 As shown, in some embodiments of the present invention, starting the backup laser device according to the difference between the actual working quantity and the optimal working quantity includes:

[0098] Step S21: obtaining the number of spare laser devices in the laser forming production line;

[0099] Step S22: determining whether the number of standby laser devices is greater than the difference between the actual working number and the optimal working number;

[0100] If yes, step S23: start the backup laser device at a preset speed.

[0101] In response to the number of spare laser devices being less than or equal to the difference between the actual working number and the optimal working number, step S24: determining whether the number of spare laser devices in the laser forming production line is equal to 0,

[0102] If not, step S25: start all standby laser devices at a preset speed.

[0103] Specifically, turning on the backup laser equipment at a preset speed is preferably turning on the backup laser equipment at a speed of 1 group / 30 minutes; turning on all the backup laser equipment at a preset speed is preferably turning on all the backup laser equipment at a speed of 1 group / 30 minutes.

[0104] If the number of spare laser devices can make up for the difference between the actual working number and the optimal working number, the spare laser devices are turned on at a preset speed until the actual working number of the laser devices in the laser forming production line is equal to the optimal working number, and then the judgment of whether there is an aging device among the laser devices in the turned-on state and its subsequent procedures are directly executed;

[0105] If the number of spare laser devices cannot make up for the difference between the actual working number and the optimal working number, the judgment on the number of laser devices will be increased, and all the spare laser devices will be turned on when the number of spare laser devices is not 0, and then the judgment on whether there are aging devices in each laser device in the turned-on state and its subsequent procedures will be directly executed; if the number of spare laser devices is 0, the judgment on whether there are aging devices in each laser device in the turned-on state and its subsequent procedures will be directly executed.

[0106] In some alternative embodiments of the present invention, the control method includes:

[0107] Step S31: Obtaining the actual work quantity;

[0108] Step S32: Obtain the optimal number of tasks;

[0109] Step S33: determining whether the actual number of jobs is less than the optimal number of jobs;

[0110] If yes, step S34: obtaining the difference between the optimal work quantity and the actual work quantity, and the number of spare laser devices;

[0111] If not, execute step S41 and subsequent steps:

[0112] Step S35: determining whether the number of spare laser devices is greater than the difference;

[0113] If yes, step S36: start the backup laser equipment one group / 30 minutes at a time according to the difference, and execute step

[0114] If not, step S37: determine whether the number of standby units is 0; if so, execute step S41 and subsequent steps; if not, step S38: turn on all standby laser devices in a manner of 1 unit / 30 minutes, and execute step S41 and subsequent steps;

[0115] Step S41: The longest accumulated working time of the laser equipment is less than 12 months;

[0116] If not, step S42: the number of optimal operating units minus N, where N is the number of the longest cumulative working units;

[0117] If yes, step S43: the number of optimal operating units + N, where N is the number of the longest cumulative working units;

[0118] Step S44: determining whether the corrected optimal number of jobs is smaller than the initial setting value;

[0119] If not, step S45: updating the optimal work quantity to a revised value;

[0120] If so, step S46: the corrected optimal working number is greater than 1; if so, execute step S45, and then return to step S32; if so, step S47: turn on all standby laser devices, and then return to step S31.
