[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In the prior art, each tool position in the tool magazine of a CNC machine tool is provided with a tool position number, and each tool also has a tool number. The tool number of the tool located at the tool position in the initial state corresponds to the tool position number of the tool position, and the tool number of the tool located on the spindle is also corresponded to the spindle, and the tool number of the tool located on the spindle is defined as the spindle tool number. The purpose of this application is to restore the tools in the tool magazine and the tools on the spindle to the initial state after the operation through the automatic tool arrangement method of the tool magazine.

[0025] To facilitate understanding, an example is given here:

[0026] Assume that the tool magazine includes 10 tool positions, and the tool position numbers of these 10 tool positions are 1, 2, ... 10. For the convenience of explanation, the tool position with tool position number 1 is referred to as tool position 1, the tool position with tool position number 2 is referred to as tool position 2, and so on. At the same time, there are 11 tools in total, and the tool numbers of these 11 tools are 0, 1, 2, ... 10. For the convenience of explanation, the tool with tool number 0 is referred to as tool 0, the tool with tool number 1 is referred to as tool 1, and so on.

[0027] In the initial state, tool No. 0 is located on the spindle, tool No. 1 is located on tool position No. 1 in the tool magazine, tool No. 2 is located on tool position No. 2 in the tool magazine, and so on. At the same time, the tool number of tool No. 0 is defined as the spindle tool number.

[0028] The purpose of this application is that after the operation, the position of each tool is consistent with the initial state.

[0029] See also Figure 1 In one embodiment, the automatic tool arrangement method of the tool magazine of the present application includes:

[0030] S110: judging whether the tool number of the tool currently on the spindle is the spindle tool number according to the tool table, wherein the tool table updates and saves the tool number of the tool currently on the spindle and the tool number of the tool currently located at each tool position in the tool magazine in real time.

[0031] Specifically, as long as the position of any tool in the tool magazine or the spindle changes, the tool table will be updated. Therefore, based on the tool table, the tool number of the tool currently on the spindle can be obtained, and it can be further determined whether the tool number of the tool currently on the spindle is the spindle tool number. If it is determined that the tool number of the tool currently on the spindle is the spindle tool number, step S130 is executed, otherwise step S120 is executed.

[0032] Still using the above example for explanation, step S110 specifically determines whether the current spindle has tool No. 0. If it has tool No. 0, execute step S130; otherwise, execute step S120.

[0033] S120: According to the tool table, the tool on the spindle is exchanged with the tool in the tool magazine so that the tool number of the tool currently on the spindle is the spindle tool number.

[0034] Specifically, the tool number of the tool on the spindle is not the spindle tool number, that is, the tool on the spindle is not tool No. 0. The machine tool replaces the tool on the spindle with the tool in the tool magazine so that tool No. 0 is replaced on the spindle.

[0035] See also Figure 2 , the process specifically includes:

[0036] S121: Obtain a target tool position number corresponding to the tool number of the tool currently located on the spindle.

[0037] Specifically, the target tool position number corresponding to the tool number of the tool currently on the spindle is, in the initial state, the tool position number of the tool position of the tool magazine where the tool currently on the spindle is located. Still using the above example, assuming that the tool currently on the spindle is tool No. 3, therefore, in the initial state, tool No. 3 is located at tool position No. 3 of the tool magazine, and therefore the corresponding target tool position number obtained in step S121 is No. 3.

[0038] It can be understood that step S121 is to obtain the target tool position number according to the tool table.

[0039] S122: Exchange the tool at the tool position with the target tool position number in the tool magazine with the tool on the spindle.

[0040] Specifically, after step S122, the tool on the spindle returns to the tool position where the tool was located in the initial state, and the tool on the tool position is returned to the spindle. For example, in the above example, tool No. 3 returns to tool position No. 3, and the tool on tool position No. 3 returns to the spindle. Of course, the above exchange process will be updated in real time in the tool table.

[0041] It can be understood that if the tool on tool position No. 3 is tool No. 0 before the exchange in step S122, then after the exchange in step S122, the tool on the spindle is tool No. 0, but if the tool on tool position No. 3 is not tool No. 0 before the exchange in step S122, then after the exchange in step S122, the tool on the spindle is not yet tool No. 0.

[0042] S123: According to the tool table, determine whether the tool number of the tool currently located on the spindle is the spindle tool number.

[0043] If the judgment result is yes, the process ends; if the judgment result is no, the process returns to step S121.

[0044] Specifically, according to the tool table, determine whether the tool number of the tool currently located on the spindle is tool No. 0. If it is not tool No. 0, return to execute step S121. If it is tool No. 0, step S120 is completed.

[0045] In order to facilitate the understanding of the above understanding, the following Figure 3 and Figure 4 Two examples are given to illustrate:

[0046] exist Figure 3 In the example, after one exchange, the tool on the spindle is already tool No. 0, so there is no need to exchange it further.

[0047] And in Figure 4 In the example, after one exchange, tool No. 1 is on the spindle, so tool No. 1 on the spindle needs to be replaced with the tool at position 1, and this process is repeated until tool No. 0 is on the spindle.

[0048] In one embodiment, the tool arrangement method further includes: in response to the number of times the step of returning to execute the step of obtaining the target tool position number corresponding to the tool number of the tool currently located on the spindle is greater than a first count threshold, issuing an alarm prompt.

[0049] Specifically, the first count threshold can be set by itself. In response to the number of times returning to execute step S121 being greater than the first count threshold, the machine tool issues an alarm to avoid program confusion and being stuck in a loop.

[0050] In one embodiment, the alarm prompt includes at least one of a sound prompt and a light prompt. Specifically, the sound prompt or the light prompt is used to remind the operator that there is a problem with the program operation, thereby reducing the time when the machine tool is stuck in a cycle and improving the processing efficiency.

[0051] S130: Determine whether the first target tool position exists in the tool magazine according to the tool table.

[0052] If it does not exist, the process ends; if it does exist, execute step S140.

[0053] Specifically, the tool position number of the first target tool position does not match the tool number of the tool located at the first target tool position stored in the tool table. That is, the tool currently at the first target tool position is not the tool that was initially at the first target tool position. For example, if the tool at position 2 in the current tool magazine is tool No. 4, then position 2 is the first target tool position.

[0054] In one embodiment, step S130 specifically includes: judging whether the tool positions in the tool magazine are the first target tool positions according to the tool table and in the order of the tool position numbers, that is, judging whether tool position No. 1 in the tool magazine is the first target tool position, and if not, judging whether tool position No. 2 is the first target tool position, and so on.

[0055] Of course, in other implementations, it is also possible to randomly determine whether the tool position in the tool magazine is the first target tool position.

[0056] S140: Exchange the tool on the first target tool position with the tool on the spindle.

[0057] Specifically, since the tool currently on the first target tool position is not the tool on the first target tool position in the initial state, the tool on the first target tool position is exchanged with the tool on the spindle. After step S140, the execution returns to step S110. After returning to step S110, the tool number of the tool on the spindle can be guaranteed to be the spindle tool number, so that the above process is continuously cycled, and the initial state can be finally restored.

[0058] In order to better understand the above scheme, Figure 4 The process is described as follows:

[0059] Combination Figure 5 After the tool on the spindle is adjusted to tool No. 0 in step S120, it is determined whether there is a first target tool position in the tool magazine. At this time, the first target tool position is found to be position 4. Then the tool on position 4 is replaced with the tool on the spindle, and then the process returns to step S120 until the tool on the spindle is tool No. 0.

[0060] Through the above method, the present application can realize automatic tool arrangement so that the distribution of the tools is the same as the initial state.

[0061] In one embodiment, the method for arranging tools further includes: in response to returning to execute the step of judging whether the tool number of the tool currently located on the spindle is the spindle tool number according to the tool table for a number of times greater than a second number threshold, an alarm is issued. Specifically, the second number threshold can be set by itself, and in response to returning to execute step S121 for a number of times greater than the second number threshold, the machine tool issues an alarm to avoid program confusion and being stuck in a loop.

[0062] In one embodiment, the alarm prompt includes at least one of a sound prompt and a light prompt. Specifically, the sound prompt or the light prompt is used to remind the operator that there is a problem with the program operation, thereby reducing the time when the machine tool is stuck in a cycle and improving the processing efficiency.

[0063] In one embodiment, the step of exchanging the tool on the spindle with the tool in the tool magazine in step S110 includes controlling the manipulator to exchange the tool on the spindle with the tool in the tool magazine.

[0064] Specifically, one end of the manipulator grabs the tool on the spindle, the machine tool rotates the tool magazine, and the other end of the manipulator grabs the tool on the tool position. The manipulator rotates 180° to replace the tool on the spindle to the tool position in the tool magazine. Correspondingly, the tool on the tool position in the tool magazine is replaced on the spindle.

[0065] In one embodiment, the method further includes generating prompt information for prompting manual proofreading after determining that the first target tool position exists in the tool magazine.

[0066] Specifically, since errors may occur during the updating of the tool table, after the tool is automatically arranged by the method of the present application, a prompt message can be generated to remind manual proofreading in order to ensure accuracy. Then, during the proofreading process, the manual tool can be removed from the wrong tool position according to the prompt message, and put into the correct tool position after proofreading, thereby improving the efficiency of tool change after tool disorder.
