Description

TECHNICAL FIELD

[0002] The hot stamping pattern of a hot stamping machine is determined by a hot stamping die. In operation, the hot stamping die is fixed, and the servo shaft of the hot stamping machine drives the hot stamping material to move to realize hot stamping of the pattern. The hot stamping modules on the hot stamping die are random in size and number, and there can be as many as 10 hot stamping modules on a hot stamping die. In order to save hot stamping material and improve the utilization rate of the hot stamping material, the positioning mode (uniform positioning or step positioning) of the servo shaft needs to be calculated in real time according to the random hot stamping pattern during hot stamping.

[0003] At present, when the positioning mode of the servo shaft is calculated, the workers calculate it on site according to the pattern to be hot stamped.

[0004] However, in the case of a small number of hot stamping patterns, the calculation by the workers is still relatively accurate. Once the number of hot stamping patterns increases, the hot stamping modules are more, the sizes of the hot stamping patterns or the hot stamping modules are inconsistent, the distances between the hot stamping modules are inconsistent, etc., the difficulty of calculation by the human brain becomes very great.

[0089] In order to make the objects, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with examples.

[0090] When the hot stamping machine stamps different patterns, the number, spacing and arrangement of the hot stamping dies used by the hot stamping dies may be the same or different. In order to meet the hot stamping requirements of different patterns, the positioning mode of the servo shaft needs to be calculated before hot stamping. Among them, the positioning mode of the servo shaft of the hot stamping machine refers to the way the servo shaft moves, whether it is a step mode or a uniform step mode, and how many steps are set when moving in a certain way. In order to solve the problem that manual calculation of the positioning mode of the servo shaft of the hot stamping machine requires a lot of calculation time, seriously affects production efficiency, and may cause the problem of low utilization rate of hot stamping materials, the present application provides a calculation method for the positioning mode of the servo shaft of the hot stamping machine. The method provides several candidate moving modes for selection by simulating the moving mode of the servo shaft on the hot stamping material when stamping the pattern. The method can be executed by any device, equipment, platform or device cluster with calculation and processing capability. As shown in Figure 1 The calculation method for the positioning mode of the servo shaft of the hot stamping machine provided by the present application includes the following steps:

[0091] Step 101, generating a simulation string corresponding to the hot stamping die according to the composition and arrangement of the hot stamping dies in the hot stamping die.

[0092] Among them, the hot stamping die includes several hot stamping dies, and the width of each hot stamping die may be the same or different; the spacing between adjacent hot stamping dies may be the same or different. The composition of the hot stamping die refers to the number of hot stamping dies, and the arrangement of the hot stamping die refers to the. The simulation string is a digital model that can be recognized by a CPU or other computing device, so as to provide candidate moving modes based on the simulation string subsequently.

[0093] Step 103, moving the simulation string in multiple rounds to simulate various positioning modes of the servo shaft of the hot stamping machine when stamping the pattern.

[0094] Moving the simulation string includes moving direction and moving distance. Moving the simulation string in one round simulates one positioning mode of the servo shaft when stamping the pattern.

[0095] Step 105, determining at least one candidate moving mode according to the moving results of the simulation string in each round.

[0096] The candidate moving mode refers to the moving mode of the simulation string applied to the moving mode of the servo shaft on the hot stamping material, which will not cause hot stamping problems, such as pattern overlap. When the moving mode of the simulation string in a certain round is applied to the moving mode of the servo shaft on the hot stamping material, the stamped pattern will be out of order, and the moving mode will be discarded directly.

[0097] Step 107, calculate the usage of the stamping material when the servo shaft is positioned in various candidate moving modes according to the simulation string and the simulation string after each round of movement.

[0098] Step 109, determine the positioning mode of the servo shaft of the stamping machine according to each usage.

[0099] The purpose of calculating the positioning mode of the servo shaft is to maximize the use of the stamping material, i.e., to improve the utilization rate of the stamping material, so as to save costs. Therefore, by calculating the usage of the stamping material when the servo shaft is positioned in various candidate moving modes and determining the positioning mode of the servo shaft of the stamping machine according to each usage, the candidate moving mode with the most reasonable utilization rate of the stamping material can be selected.

[0100] The method provided by the embodiment of the present application can generate a simulation string corresponding to the stamping die according to the composition and arrangement of the stamping modules in the stamping die, simulate various positioning modes of the servo shaft of the stamping machine when stamping a pattern by moving the simulation string, and provide a method for calculating the positioning mode of the servo shaft of the stamping machine by using a computer or other device with computing function. The positioning mode of the servo shaft of the stamping machine can be quickly calculated by using the method, which can not only save calculation time and improve production efficiency, but also facilitate the selection of a positioning mode with a high utilization rate of the stamping material by calculating the usage of the stamping material when the servo shaft is positioned in various candidate moving modes and determining the positioning mode of the servo shaft of the stamping machine according to each usage, thereby saving costs. In addition, since the calculation is performed by a machine, even if the number of stamping patterns increases, the stamping modules are more, the sizes of the stamping patterns or the stamping modules are inconsistent, the distances between the stamping modules are inconsistent, or the like, accurate and fast calculation can still be performed, and the calculation time can be shortened and the labor cost can be saved.

[0101] Specifically, as shown in FIG. 1, step 101 includes the following steps when generating a simulation string corresponding to the stamping die according to the composition and arrangement of the stamping modules in the stamping die: Figure 2

[0102] Step 1011, obtain the width, arrangement distance and arrangement sequence of each stamping module in the stamping die.

[0103] For example, the present embodiment provides a stamping die attribute UI interface, and an operator can input the number of stamping modules, the width, arrangement distance and arrangement sequence of each stamping module and other information on the UI interface. On this basis, the width, arrangement distance and arrangement sequence of each stamping module in the stamping die can be input by the operator in advance, and when the width, arrangement distance and arrangement sequence of each stamping module in the stamping die are obtained, the data input and stored by the user can be directly obtained.

[0104] ​In step 1013, the arrangement string of the hot stamping modules is determined according to the width, arrangement interval and arrangement sequence of the hot stamping modules.

[0105] The arrangement string can reflect the width, arrangement interval and arrangement sequence of the hot stamping modules. For example, if the hot stamping mold comprises three hot stamping modules, i.e., hot stamping module a, hot stamping module b and hot stamping module c arranged in sequence, the width of the hot stamping module a, the hot stamping module b and the hot stamping module c is 2 cm, 1 cm and 1 cm respectively, the arrangement interval between the hot stamping module a and the hot stamping module b is 6 cm, and the arrangement interval between the hot stamping module b and the hot stamping module c is 4 cm, the arrangement string of the hot stamping modules can be represented as 26141.

[0106] In step 1015, the unit length during the conversion of the string is obtained.

[0107] The unit length can be set as needed, and the embodiment does not make specific limitation thereon. In order to facilitate the conversion of the arrangement string, the unit length can be the minimum value between the width and the arrangement interval of the hot stamping modules. In combination with the above example, the unit length can be 1 cm.

[0108] In step 1017, the quotient value between the character representing the width of the hot stamping module in the arrangement string of the hot stamping modules and the unit length is converted into a corresponding number of first characters, and the quotient value between the character representing the arrangement interval in the arrangement string of the hot stamping modules and the unit length is converted into a corresponding number of second characters.

[0109] The first character and the second character can be set at will as needed, such as A and B, @ and #, 8 and 9, etc. However, in order to facilitate the recognition of the CPU and other computing devices and improve the computing efficiency, the first character and the second character are preferably set to 1 and 0 which can be directly recognized by the computing device. In order to facilitate the conversion of the simulation string, the unit length is preferably set to the minimum value between the width and the arrangement interval of the hot stamping modules.

[0110] In step 1019, the first character and the second character are combined according to the arrangement sequence to obtain the simulation string corresponding to the hot stamping mold.

[0111] In order to enable the simulation string to represent the width, arrangement interval and arrangement sequence of the hot stamping modules, the first character and the second character are combined according to the arrangement sequence, and the simulation string can be obtained.

[0112] For example, when the arrangement string of the hot stamping modules is 26141, the unit length is 1 cm, and the first character and the second character are 1 and 0 respectively, the simulation string is 11000000100001.

[0113] In another embodiment of the present invention, the purpose of step 103, which involves multiple rounds of simulated movement of the simulated string, is to simulate various positioning methods when the servo axis is hot-pressing the pattern, so that the optimal servo axis positioning method can be found subsequently. The direction and distance of movement of each round of simulated movement of the simulated string can be determined in combination with the positioning method when the hot-pressing machine's servo axis is hot-pressing the pattern.

[0114] Specifically, in one round of movement of the simulated string, the movement can be either moving a certain distance in one direction, or moving a certain distance in one direction followed by moving another distance in the same direction. That is, one round of movement of the simulated string can include moving the simulated string once or moving it multiple times (at least twice). When one round of movement of the simulated string includes at least two movements, and each movement is the same distance, this movement method is called a uniform movement method; when the distances of each movement differ, this movement method is called a skip movement method. Furthermore, in a skip movement method, there can be cases where the first few movements are the same distance, but the distance of the last movement differs from the distances of the previous movements.

[0115] Based on the above, in step 103, during each round of moving the simulated string, either a skipping or uniform step method can be used to move the simulated string to simulate a positioning method when the hot stamping machine's servo axis is used to stamp the pattern. Specifically, there are two methods:

[0116] The first method: This method uses a skip-step movement of the simulated string to simulate the positioning of a hot stamping machine's servo axis when stamping patterns. The implementation of this method involves determining the step size when moving the simulated string using the skip-step movement technique. The step size can be set as needed.

[0117] In one specific embodiment, the step size of the skip-step method includes a first step size and a second step size. The first step size is determined based on the maximum width of each hot stamping module, and the second step size is determined based on the length of the hot stamping mold and the number of moves according to the first step size. In this case, during one round of movement, the simulated string is first moved M times according to the first step size, and then the simulated string is moved once according to the second step size. M is obtained by rounding down the ratio between the minimum distance between adjacent hot stamping modules and the maximum width of each hot stamping module.

[0118] like Figure 3 As shown, it is a schematic diagram of this type of jump movement. Figure 3 The number 0 represents the arrangement before the hot stamping mold moves, number 1 represents the arrangement after the first movement, number 2 represents the arrangement after the second movement, and number 3 represents the arrangement after the third movement. Figure 3 Therefore, the distance that needs to be moved for the fourth time is the sum of the length of the hot stamping mold and M times the length of the first step.

[0119] It should be noted that the first mode only exemplarily lists the case that the one round jump mode includes moving with two moving steps, however, in actual hot stamping process, the number of moving steps included in the one round jump mode can be set as multiple according to needs.

[0120] The second mode: a positioning mode for moving the simulation string in a uniform step mode to simulate the hot stamping pattern of the servo shaft of the hot stamping machine, including: determining a specified step length as the moving step length when moving the simulation string in the uniform step mode, and moving the simulation string according to the specified step length. Wherein, the specified step length can be set according to needs, which is not specifically limited in the embodiment.

[0121] Further, in step 103, when moving the simulation string in multiple rounds, the number of rounds of moving the simulation string can be obtained by rounding off the ratio between the minimum distance between adjacent hot stamping modules and the maximum width of each hot stamping module. Through this way of determining the number of moving rounds, a reasonable number of candidate moving modes can be selected, and the problem of low calculation efficiency caused by large calculation amount can be avoided.

[0122] Optionally, in step 105, when determining at least one candidate moving mode according to the moving result of the simulation string in each round, since the pattern overlapping phenomenon occurs when the moving result of the simulation string is applied to the servo shaft positioning, which will cause the printing error of the hot stamping pattern, therefore, in the specific implementation, for each round of moving, it is judged whether the pattern overlapping phenomenon will occur when the moving result of the simulation string is applied to the servo shaft positioning; if the pattern overlapping phenomenon will not occur when the moving result of the simulation string is applied to the servo shaft positioning, then the moving mode of the simulation string in this round is determined as a candidate moving mode.

[0123] In combination with the above example, when the simulation string is 11000000100001 and the moving mode is moving one unit length (1 cm) to the right, the simulation string and the simulation string after moving are as follows: 11000000100001 11000000100001

[0126] Therefore, after moving according to this moving mode, the pattern printed by the hot stamping module a overlaps, therefore, this is an invalid movement, and this moving mode cannot be used as a candidate moving mode.

[0127] When the simulation string is 11000000100001 and the moving mode is moving one unit length (2 cm) to the right, then after moving, the pattern overlapping phenomenon will not occur, therefore, the moving mode of moving two unit lengths to the right is a candidate moving mode.

[0128] Specifically, when the first character and the second character are 1 and 0 respectively, in judging whether the pattern overlap phenomenon will occur when the moving result of the simulation string is applied to the positioning of the servo axis, the simulation string and the simulation string after moving can be subjected to AND operation (the empty position after moving is filled with 0), and when the AND operation result is non-zero, it is determined that the pattern overlap phenomenon will occur when the moving result of the simulation string is applied to the positioning of the servo axis; when the AND operation result is 0, it is determined that the pattern overlap phenomenon will not occur when the moving result of the simulation string is applied to the positioning of the servo axis.

[0129] In combination with the above, since the space occupied by the first character simulation hot stamping material and the space not occupied on the second character simulation hot stamping material, in another embodiment of the present application, step 107 can calculate the usage rate of the hot stamping material when the servo axis is positioned in various candidate moving ways according to the simulation string and the simulation string after each round of moving, respectively, according to the proportion of the number of the first character and the second character in the simulation string and the simulation string after each round of moving.

[0130] Specifically, when the first character and the second character are 1 and 0 respectively, for a certain round of moving, the simulation string and the simulation string after moving can be subjected to OR operation, and the proportion of 1 and 0 in the OR operation result is used to determine the usage rate of the hot stamping material corresponding to the candidate moving way.

[0131] For example, when the simulation string is 11000000100001 and the moving way is moving two unit lengths (1 cm) to the right, the result of OR operation of the simulation string and the simulation string after moving is 1111000010100101, and the proportion of the number 1 in the result can be used to determine that the usage rate of the hot stamping material when positioned in this candidate moving way is 8 / 16, i.e. 50%.
