Technical Field

[0001] The invention relates to the technical field of wire cutting, and in particular to a method and system for controlling the tension force of a wire cutting molybdenum wire. Background Art

[0002] With the development of science and technology, the emergence of various advanced manufacturing technologies has changed the traditional processing methods of many industries. However, in the wire cutting industry, there has not been a big breakthrough and development in technology in recent years. On the other hand, there is no other more advanced processing method to replace the wire cutting processing method. Therefore, it is very necessary and valuable to innovate and upgrade the technology on the existing wire cutting equipment.

[0003] In the existing medium-wire cutting equipment, the molybdenum wire is transported through a roller mechanism and several bearing components to fix the molybdenum wire's circulation. Since the length of the molybdenum wire is relatively long during the entire circulation process, in order to control the tension of the molybdenum wire, some pressure blocks are used on the mechanical structure to adjust and assist in fixing the molybdenum wire and achieve the adjustment of the molybdenum wire tension. In addition, in order to monitor the molybdenum wire breakage problem in real time during the processing, a contact mechanical structure is required to press on the molybdenum wire, and the feedback of the electrical signal loaded on it is used to monitor whether the molybdenum wire has broken.

[0004] With respect to the above-mentioned related technologies, the inventors found that there are the following defects: it is impossible to effectively analyze the loss of the molybdenum wire and adjust the tension force according to the loss, which reduces the accuracy of the processed product. Summary of the invention

[0010] If yes, then analyze and judge that the tension of the wire cutting molybdenum wire is correct;

[0011] If not, then analyze and determine the adjustment degree of the wire-cut molybdenum wire tension based on the comparison result between the actual size of the molybdenum wire and the median value of the size range, and the corresponding relationship between the comparison result and the adjustment degree of the wire-cut molybdenum wire tension, and adjust the wire-cut molybdenum wire tension according to the analysis and determined adjustment degree of the wire-cut molybdenum wire tension.

[0020] Optionally, reanalyze to determine the problem distribution probability including:

[0021] Obtain the average number of occurrences of other time ranges that are consistent with the time interval corresponding to the preset time range and that do not fall within the size range after adjustment;

[0022] The weight coefficient is determined based on the ratio of the average number of occurrences to the number of occurrences that do not fall into the size range after adjustment within the preset time range. The problem distribution probability is re-analyzed based on the weight coefficient determined by the analysis.

[0023] Optionally, reanalyze to determine the problem distribution probability including:

[0041] The present application is further described in detail below in conjunction with the accompanying drawings.

[0042] Reference Figure 1 , is a method for controlling the tension force of a molybdenum wire cut by a wire cutting disclosed in the present application, comprising:

[0043] Step S100, obtaining the position and actual size of the molybdenum wire during the wire cutting process.

[0044] The position and actual size of the molybdenum wire during wire cutting are obtained as follows: the image of the molybdenum wire is read in real time by an industrial camera, and the actual size of the molybdenum wire is calculated by software.

[0045] Step S200, according to the preset correspondence between the position of the molybdenum wire and the size range, analyze and obtain whether the actual size of the molybdenum wire at different positions falls within the size range. If yes, execute step S300; if not, execute step S400.

[0046] Among them, the corresponding relationship between the preset position of the molybdenum wire and the size range is obtained as follows: set the size of the molybdenum wire in the software, adjust the tension of the molybdenum wire to a suitable situation, use the industrial camera to take a photo to record the position of the molybdenum wire as the standard position; take a photo with the camera, and calculate the size of the molybdenum wire in the image as the standard size.

[0047] Step S300, analyzing and determining whether the tension of the wire-cut molybdenum wire is correct.

[0048] Step S400, analyze and determine the adjustment degree of the wire-cut molybdenum wire tension according to the comparison result between the actual size of the molybdenum wire and the median value of the size range, and the corresponding relationship between the comparison result and the adjustment degree of the wire-cut molybdenum wire tension, and adjust the wire-cut molybdenum wire tension according to the analysis and determined adjustment degree of the wire-cut molybdenum wire tension.

[0049] Among them, the comparison result of the actual size of the molybdenum wire and the median of the size range is the ratio of the actual size of the molybdenum wire to the median of the size range, and the corresponding relationship between the comparison result and the adjustment degree of the wire-cut molybdenum wire tension is to determine the adjustment degree of the wire-cut molybdenum wire tension according to the ratio.

[0050] Among them, the process of adjusting the tension of the wire-cut molybdenum wire according to the adjustment degree of the wire-cut molybdenum wire tension determined by analysis is as follows: the tension adjustment module controls the pulse power supply to turn off the high frequency and stop processing the workpiece; the tension adjustment device controls the wire storage drum to reduce the rotation speed and slowly transport the wire to adjust the tension of the molybdenum wire so that the tension of the molybdenum wire returns to the set tension; the tension adjustment device controls the pulse power supply to turn on the high frequency again and process the workpiece again.

[0051] exist Figure 1 After step S400, it is further considered that after the wire cutting molybdenum wire tension adjustment is completed, the influence of the molybdenum wire on the molybdenum wire tension change is not as expected. In this case, further analysis and processing are required. For details, refer to Figure 2 The illustrated embodiment is described in detail.

[0052] Reference Figure 2 The method for controlling the tension of the molybdenum wire cut wire further includes the following steps after adjusting the tension of the molybdenum wire cut wire according to the adjustment degree of the tension of the molybdenum wire cut wire determined by analysis:

[0053] Step S500, analyzing whether the actual sizes of the molybdenum wire at different positions after the wire cutting molybdenum wire tensioning force adjustment are within the size range. If yes, execute step S600; if no, execute step S700.

[0054] Step S600, analyzing whether the adjustment degree of the tension force of the wire cutting molybdenum wire is correct.

[0055] Step S700: Analyze and determine the problem distribution probability based on the correspondence between the adjusted size range and the problem distribution probability, and send it to the terminal held by the person in charge.

[0056] Among them, the analysis of the problem distribution probability is determined as follows: the situation that does not fall into the size range after adjustment is brought into a preset database that stores the corresponding relationship between the size range that does not fall into the adjustment and the problem distribution probability, and the terminal held by the person in charge of the problem can be queried to obtain the terminal held by the person in charge. The terminal held by the person in charge can be a mobile phone, computer or other terminal device.

[0057] exist Figure 2 In step S700, it is further considered that when determining the problem distribution probability, the distribution situation in the most recent time range should be considered, so that the determined problem distribution probability is more accurate and reasonable. Figure 3 The illustrated embodiment is described in detail.

[0058] Reference Figure 3 , the analysis of the problem distribution probability is determined as follows:

[0059] Step S710, obtaining the number of occurrences that do not fall within the size range after adjustment within a preset time range.

[0060] Step S720, if the number of occurrences of not falling into the size range after adjustment within the preset time range is less than the preset number, the problem distribution probability is analyzed and determined based on the correspondence between the size not falling into the size range after the tension force of the molybdenum wire cutting equipment of the same model is adjusted and the problem distribution probability.

[0061] The number of occurrences that do not fall within the size range after adjustment within the preset time range can be set as needed, for example, it can be set to 4 times, and the preset time range can be half a month or 1 month.

[0062] Step S730, if the number of occurrences of not falling into the size range after adjustment within the preset time range is greater than or equal to the preset number, then the problem distribution probability is re-analyzed and determined based on the problem distribution probability determined within the preset time range, the correspondence between the size not falling into the size range and the problem distribution probability after the tension force of the molybdenum wire cutting equipment of the same model is adjusted, and the weight coefficients of different time ranges.

[0063] For example, the weight coefficient corresponding to the problem distribution probability determined within the preset time range is 0.3, and the distribution probability of the problem determined within the preset time range is 1:2:2 according to problem A, problem B, and problem C; it can be converted to 20%:40%:40%. The weight coefficient of the corresponding relationship between the size of the same model of wire cutting equipment not falling within the size range after the tension force of the molybdenum wire is adjusted and the problem distribution probability is 0.7, and the distribution probability of the problem determined within the preset time range is 3:3:4 according to problem A, problem B, and problem C, which can be converted to 30%:30%:40%. Then the distribution probability after the weight coefficient becomes 27%:33%:40%, that is, 27:33:40.

[0064] exist Figure 3 In step S730, the influence of the problem distribution probability within the preset time range on the weight coefficient is further considered, and the problem distribution probability is further re-analyzed and determined. Figure 4 The illustrated embodiment is described in detail.

[0065] Reference Figure 4 , re-analyze and determine the problem distribution probability including:

[0066] Step S731, obtaining the average number of occurrences of other time ranges that are consistent with the time interval corresponding to the preset time range and that do not fall within the size range after adjustment.

[0067] For example, assuming that the time interval corresponding to the preset time range is 1 month, the preset time range is the most recent month, and other time ranges consistent with the time interval corresponding to the preset time range are the previous time ranges every other month.

[0068] Step S732, analyzing and determining a weight coefficient based on the ratio of the average number of occurrences to the number of occurrences that do not fall within the size range after adjustment within a preset time range, and re-analyzing and determining the problem distribution probability based on the weight coefficient determined by the analysis.

[0069] exist Figure 3 In step S730, the weight coefficient is further considered to be related to the situation preferred by the person in charge, so further analysis is required. Figure 5 The illustrated embodiment is described in detail.

[0070] Reference Figure 5 , re-analyze and determine the problem distribution probability including:

[0071] Step S73a, obtaining the identity information of the notified person in charge.

[0072] Step S73b, analyzing and determining the weight coefficient according to the correspondence between the identity information of the person in charge and the setting of the weight coefficient, and re-analyzing and determining the problem distribution probability according to the analyzed and determined weight coefficient.

[0073] The re-analysis of the problem distribution probability is determined as follows: taking the identity information of the person in charge as the query object, querying and obtaining the weight coefficient from a preset database storing the corresponding relationship between the identity information of the person in charge and the setting of the weight coefficient.

[0074] exist Figure 2 After step S700, it is further considered that when the person in charge arrives at the scene to deal with the problem, he can know the possibility of failure in advance and the problems that may be encountered in advance. Figure 6 The illustrated embodiment is described in detail.

[0075] Reference Figure 6 The method for controlling the tension force of the molybdenum wire cut by wire cutting also includes steps after the data is sent to the terminal held by the person in charge, which are as follows:

[0076] Step S800, obtaining the failure rate of the person in charge in handling different issues.

[0077] The failure rates of the responsible persons in handling different problems may be obtained by querying from a preset database storing the failure rates of the responsible persons in handling different problems.

[0078] Step S900, according to the corresponding relationship between the failure rate of the person in charge in handling different problems and the problem distribution probability, the failure rate of problem handling is analyzed and determined, and the problems are specifically sorted from high to low according to the failure rate, and loaded into the text message sent to the terminal held by the person in charge.

[0079] exist Figure 6 After step S900, it is further considered to facilitate the person in charge to understand the cause of the failure more clearly so as to make more appropriate preparations. Figure 7 The illustrated embodiment is described in detail.

[0080] Reference Figure 7 The method for controlling the tension force of the molybdenum wire for wire cutting also includes the following steps after the failure rates of the problems are specifically sorted from high to low and loaded into a text message sent to the terminal held by the person in charge, which are as follows:

[0081] Step SA00, obtaining the reasons corresponding to the failure rates of the responsible persons in handling different problems.

[0082] Step SB00, based on the problem distribution probability and the reasons corresponding to the failure rate of the person in charge in handling different problems, the distribution probability of the reasons corresponding to the failure is summarized and analyzed, and loaded into a text message sent to the terminal held by the person in charge.

[0083] Based on the same inventive concept, an embodiment of the present invention provides a wire cutting molybdenum wire tension control system, including a memory and a processor, wherein the memory stores a program that can be executed on the processor to implement the following Figures 1 to 7 Procedure for either method.
