Description

Technical Field

[0001] The present invention relates to the technical field of CNC automated processing, and in particular to a CNC automated processing system and a control method. Background Art

[0002] CNC machining center is a kind of high-efficiency, automated and high-precision machine tool equipment, which is not only used in machinery manufacturing industry, but also widely covers many fields such as aerospace, automobile industry and electronics industry. CNC machining center integrates multiple processing technologies such as drilling, milling, boring, reaming and tapping, and can complete complex processing of multiple surfaces in one clamping, aiming to improve production efficiency and reduce labor intensity.

[0003] At present, a CNC machining center usually includes several key components, including the machine tool body, CNC system, automatic tool changer (ATC) and auxiliary devices, among which: the machine tool body includes mechanical structures such as the bed, workbench, and spindle; the CNC system controls the core of the machining center, and controls the operation and coordination of the equipment through programming and algorithms; the automatic tool changer realizes the automatic replacement of multiple tools to improve machining efficiency; the automatic tool changer usually includes a tool magazine and a manipulator, in which the tool magazine stores multiple tools, and the tools in the tool magazine are arranged according to pre-set rules and automatically replaced by the automatic tool changer to realize tool switching between different machining processes; auxiliary devices such as cooling systems and chip removal systems ensure the smooth progress of the machining process. During the tool change process, the CNC system issues a tool change command according to the machining program, and the tool magazine selects the corresponding tool according to the tool change command. The automatic tool changer takes the selected tool out of the tool magazine and installs it on the spindle, and puts the original tool back into the tool magazine. After the tool change is completed, the CNC system continues to execute the machining program.

[0004] like Figure 1 and Figure 2 As shown, in order to improve processing efficiency and safety, the existing workshop combines multiple CNC machine tools (CNC machining centers) into an automated processing system, and is equipped with one or more workpiece material warehouses and automatic loading and unloading robots to load and unload multiple CNC machine tools, which not only improves processing efficiency and safety, but also reduces the number of workers to reduce costs. However, the tool magazine (tool tray) of the CNC machine tool can only clamp 36 tools, and the tool magazine of each CNC machine tool is a standard tool magazine, that is, the tools clamped in the tool magazine of each CNC machine tool are fixed 36 tools, which can only meet the processing of relatively conventional workpieces.

Among them, the workpiece material warehouse is filled with workpiece raw materials to be processed. The automatic loading and unloading robot is provided with a mechanical arm, and the workpiece is grasped by the mechanical arm. The workpiece can be an electrode for electric spark machining, and of course it can also be other workpieces that can be processed by CNC machine tools.

[0031] In this embodiment, multiple CNC machine tools include a first type of CNC machine tools, a second type of CNC machine tools and a third type of CNC machine tools. The first type of CNC machine tools has a first type of tool magazine for processing a first workpiece, the second type of CNC machine tools has a second type of tool magazine for processing a second workpiece, and the third type of CNC machine tools has a third type of tool magazine for processing a third workpiece. The tools in the first type of tool magazine are not completely the same as the tools in the second type of tool magazine, and the tools in the first type of tool magazine and the tools in the second type of tool magazine are not completely the same as the tools in the third type of tool magazine.

[0032] Please refer to Figures 5 to 7 As shown, the first type of tool magazine, the second type of tool magazine and the third type of tool magazine have some of the same tools, so that the first type of CNC machine tool, the second type of CNC machine tool and the third type of CNC machine tool can all process relatively conventional types of workpieces. The first type of tool magazine, the second type of tool magazine and the third type of tool magazine also have different tools, so that the first type of CNC machine tool, the second type of CNC machine tool and the third type of CNC machine tool can each process a special type of workpiece.

[0033] The first workpiece includes a first type of workpiece and a second type of workpiece, and the first type of tool magazine has a tool for processing the first type of workpiece and a tool for processing the second type of workpiece.

Among them, the first type of workpiece is a relatively conventional type of workpiece, which can be processed by the first type of CNC machine tool, the second type of CNC machine tool and the third type of CNC machine tool; while the second type of workpiece, the third type of workpiece and the fifth type of workpiece are special types of workpieces, the second type of workpiece can only be processed by the first type of CNC machine tool, the third type of workpiece can only be processed by the second type of CNC machine tool, and the fifth type of workpiece can only be processed by the third type of CNC machine tool.

[0034] Of course, in other embodiments, the first workpiece includes a first type of workpiece and a second type of workpiece, and the first type of tool magazine has a tool for processing the first type of workpiece and a tool for processing the second type of workpiece. The second workpiece includes a third type of workpiece and a fourth type of workpiece, and the second type of tool magazine has a tool for processing the third type of workpiece and a tool for processing the fourth type of workpiece. The third workpiece includes a fifth type of workpiece and a sixth type of workpiece, and the third type of tool magazine has a tool for processing the fifth type of workpiece and a tool for processing the sixth type of workpiece. That is, the first type of CNC machine tool, the second type of CNC machine tool, and the third type of CNC machine tool process different types of workpieces respectively, the first type of workpiece and the second type of workpiece can only be processed by the first type of CNC machine tool, the third type of workpiece and the fourth type of workpiece can only be processed by the second type of CNC machine tool, and the fifth type of workpiece and the sixth type of workpiece can only be processed by the third type of CNC machine tool.

[0035] Alternatively, in other embodiments, the plurality of CNC machine tools may only include the first type of CNC machine tools and the second type of CNC machine tools, the first type of CNC machine tools having the first type of tool magazine for processing the first workpiece, the second type of CNC machine tools having the second type of tool magazine for processing the second workpiece, and the tools of the first type of tool magazine are not completely the same as the tools of the second type of tool magazine, that is, the tool magazines of the plurality of CNC machine tools are only divided into two different tool magazines. For example, the first workpiece includes the first type of workpiece and the second type of workpiece, the first type of tool magazine has the tool for processing the first type of workpiece and the tool for processing the second type of workpiece; the second workpiece includes the first type of workpiece and the third type of workpiece, the second type of tool magazine has the tool for processing the first type of workpiece and the tool for processing the third type of workpiece. That is, the first type of workpiece can be processed by both the first type of CNC machine tools and the second type of CNC machine tools, the second type of workpiece can only be processed by the first type of CNC machine tools, and the third type of workpiece can only be processed by the second type of CNC machine tools. Alternatively, the first workpiece includes a first type of workpiece and a second type of workpiece, and the first type of tool magazine has a tool for processing the first type of workpiece and a tool for processing the second type of workpiece; the second workpiece includes a third type of workpiece and a fourth type of workpiece, and the second type of tool magazine has a tool for processing the third type of workpiece and a tool for processing the fourth type of workpiece. That is, the first type of workpiece and the second type of workpiece can only be processed by the first type of CNC machine tool, and the third type of workpiece and the fourth type of workpiece can only be processed by the second type of CNC machine tool. Among them, the number of types in the CNC machine tool can be increased or decreased according to the type of workpiece to be processed, not limited to two types of CNC machine tools or three types of CNC machine tools, and multiple CNC machine tools can also have five types of CNC machine tools or six types of CNC machine tools, etc., and the number of types of tool magazines changes synchronously with the number of types of CNC machine tools.

[0036] In this embodiment, the plurality of CNC machine tools are arranged in two rows and multiple columns, and the second type of CNC machine tools and the third type of CNC machine tools are located in the same row and are located in different rows from the first type of CNC machine tools. Figure 3 As shown, multiple CNC machine tools and workpiece magazines are arranged in two rows and five columns. The five CNC machine tools in the first row are all first-type CNC machine tools with first-type tool magazines, the first two CNC machine tools in the second row are all second-type CNC machine tools with second-type tool magazines, and the last two CNC machine tools in the second row are all third-type CNC machine tools with third-type tool magazines. The workpiece magazine is located in the middle of the second row to facilitate automatic loading and unloading robots to pick up materials.

[0037] Of course, in another embodiment, multiple CNC machine tools are arranged in two rows and multiple columns, both rows of CNC machine tools have the first type of CNC machine tools, the second type of CNC machine tools are located in one row of CNC machine tools, and the third type of CNC machine tools are located in the other row of CNC machine tools. Figure 4 As shown, multiple CNC machine tools together with workpiece material magazines are arranged in two rows and five columns, the first two CNC machine tools in the first row and the first two CNC machine tools in the second row are all first-class CNC machine tools with first-class tool magazines, the last three CNC machine tools in the first row are all second-class CNC machine tools with second-class tool magazines, the last two CNC machine tools in the second row are all third-class CNC machine tools with third-class tool magazines, and the workpiece material magazine is located in the middle of the second row to facilitate automatic loading and unloading robots to pick up materials. Among them, the number of first-class CNC machine tools, second-class CNC machine tools and third-class CNC machine tools can be adjusted according to the number of first workpieces, the number of second workpieces and the number of third workpieces to ensure that the workload of all CNC machine tools is the same.

[0038] Figure 8 is a flowchart of the control method in Embodiment 1 of the present invention. Figure 8 As shown, the present application also provides a control method of a CNC automated processing system, which is used to control the CNC automated processing system as described above. The control method includes: Step S11: Obtain the processing type of the workpiece and confirm the tool required for processing the workpiece. Specifically, the processing type of the workpiece and the number of workpieces of each processing type can be manually entered into the system in advance, and the tool and processing path required for each processing type are manually designed in advance and entered into the system, and can be directly called in the system during processing.

[0039] Step S12: The automatic loading and unloading robot installs the workpiece on the CNC machine tool with the corresponding tool according to the processing type. Specifically, the system determines the type of workpiece that should be processed at this time according to the program setting, and then sends the instruction to the automatic loading and unloading robot. The automatic loading and unloading robot installs the workpiece on the CNC machine tool with the corresponding tool according to the instruction (the instruction corresponds to the processing type). For example, the system confirms that the second type of workpiece should be processed at this time, and then sends the instruction to the automatic loading and unloading robot. Since only the first type of CNC machine tool can process the second type of workpiece, the automatic loading and unloading robot installs the workpiece on the first type of CNC machine tool according to the instruction. Alternatively, the system confirms that the first type of workpiece should be processed at this time, and then sends the instruction to the automatic loading and unloading robot. Since the first type of CNC machine tool, the second type of CNC machine tool and the third type of CNC machine tool can all process the first type of workpiece, the automatic loading and unloading robot installs the workpiece on any idle CNC machine tool according to the instruction.

[0040] Step S13: The CNC machine tool selects a corresponding processing program according to the processing type and processes the workpiece. The processing path of each processing type is manually designed in advance and entered into the system, and can be directly called in the system during processing.

[0041] [Example 2] Fig. 9 Schematic diagram of the planar structure of the CNC automated processing system in the second embodiment of the present invention. Fig. 9 As shown, the CNC automated processing system provided by the second embodiment of the present invention is the same as that provided by the first embodiment ( Figures 2 to 7 ) are basically the same, except that: In this embodiment, the CNC automated processing system includes an automatic tool changing robot and a spare tool magazine, wherein the spare tool magazine is used to provide tools to the automatic tool changing robot, and the automatic tool changing robot is used to replace tools in the tool magazines of multiple CNC machine tools. By replacing tools in the tool magazines of multiple CNC machine tools through the automatic tool changing robot, the number of types of tool magazines in multiple CNC machine tools and the number of each type of tool magazine can be adjusted, that is, the number of types of CNC machine tools and the number of each type of CNC machine tools can be adjusted.

[0042] For example, Fig. 9As shown, there are now three types of tool magazines, namely, the first type of tool magazine for the first type of CNC machine tools, the second type of tool magazine for the second type of CNC machine tools, and the third type of tool magazine for the third type of CNC machine tools; wherein, the number of the first type of CNC machine tools with the first type of tool magazine is five, the number of the second type of CNC machine tools with the second type of tool magazine is two, and the number of the third type of CNC machine tools with the third type of tool magazine is two. When the system only needs two types of tool magazines, the automatic tool changing robot replaces the tools of the third type of tool magazine of the third type of CNC machine tools, for example, when replacing the tools with the tools of the first type of tool magazine, the third type of CNC machine tools becomes the first type of CNC machine tools with the first type of tool magazine, at which time, the number of the first type of CNC machine tools with the first type of tool magazine becomes seven; of course, for example, when replacing the tools with the tools of the second type of tool magazine, the third type of CNC machine tools becomes the second type of CNC machine tools with the second type of tool magazine, at which time, the number of the second type of CNC machine tools with the second type of tool magazine becomes four. Of course, in other embodiments, when the system only needs four types of tool magazines, the automatic tool changing robot can replace the tools of the first type of tool magazines of the two first type CNC machine tools, for example, by replacing them with tools of the fourth tool magazine, so that the two first type CNC machine tools become the fourth CNC machine tools with the fourth tool magazine. At this time, the number of first type CNC machine tools with the first type of tool magazine becomes three, and the number of fourth CNC machine tools with the fourth tool magazine becomes two. Among them, the number of types of tool magazines in multiple CNC machine tools and the number of each type of tool magazine can be adjusted according to the type and number of workpieces to be processed, that is, the number of types of CNC machine tools and the number of each type of CNC machine tools can be adjusted according to the type and number of workpieces to be processed, but it is not limited to this.

[0043] Fig.10 This is one of the flow charts of the control method in the second embodiment of the present invention. Fig.11 This is the second flowchart of the control method in the second embodiment of the present invention. Fig.10 and Fig.11 As shown, the control method of a CNC automated machining system provided in this embodiment is similar to that of Embodiment 1 ( Figure 8 ) is basically the same as the control method of the CNC automated machining system in the embodiment, except that, in this embodiment, the control method includes: like Fig.10As shown, step S21: obtain the processing types of all workpieces, and determine the types of tool magazines required for all processing types. Step S22: the automatic tool changing robot adjusts the tool magazine of the CNC machine tool according to the type of tool magazine. For example, the processing types of the workpieces include the first type of workpieces, the second type of workpieces, and the third type of workpieces, that is, the system only needs two types of tool magazines (two types of CNC machine tools). Therefore, the automatic tool changing robot replaces the tools of the third type of tool magazine of the third type of CNC machine tool, for example, when the tools are replaced with the tools of the first type of tool magazine, the third type of CNC machine tool becomes the first type of CNC machine tool with the first type of tool magazine. At this time, the number of the first type of CNC machine tools with the first type of tool magazine becomes seven; of course, for example, when the tools are replaced with the tools of the second type of tool magazine, the third type of CNC machine tool becomes the second type of CNC machine tool with the second type of tool magazine. At this time, the number of the second type of CNC machine tools with the second type of tool magazine becomes four.

[0044] like Fig.11 As shown, step S31: obtaining the number of workpieces corresponding to different processing types; step S32: the automatic tool changing robot adjusts the number of CNC machine tools corresponding to different tool magazines according to the number of workpieces corresponding to different processing types. For example, the processing types of workpieces include first type workpieces, second type workpieces, and third type workpieces. The number of first type workpieces is 900, the number of second type workpieces is 400, and the number of third type workpieces is 500. The automatic tool changing robot will replace the tools in the third type tool magazine of all third type CNC machine tools and the tools in the first type tool magazine of a first type CNC machine tool with tools from the second type tool magazine, thereby turning all third type CNC machine tools and one first type CNC machine tool into second type CNC machine tools with second type tool magazines. At this time, the number of first type CNC machine tools with first type tool magazines becomes four, and the number of second type CNC machine tools with second type tool magazines becomes five, thereby allowing each first type CNC machine tool to be assigned to process 100 first type workpieces and 100 second type workpieces, and each second type CNC machine tool to be assigned to process 100 first type workpieces and 100 third type workpieces, so that all CNC machine tools can be used efficiently and processing efficiency can be improved.

[0045] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of the first embodiment and will not be described in detail here.

[0046] Fig.12 It is a statistical chart of electrodes processed by CNC automated processing systems in the prior art. Fig.13 This is a statistical chart of electrodes processed by the CNC automated processing system in this application. Fig.12As shown in the figure, the existing CNC automated processing system processes electrodes by automated processing + manual processing, of which automated processing accounts for 60% of all processed electrodes, and manual processing accounts for 40% of all processed electrodes. Therefore, the proportion of automated processing in the existing technology is relatively low, and it is difficult to improve the processing efficiency, which has a serious impact on workshop production, mold delivery time, and mold cost. Fig.13 As shown, after the improvements of this application, automated processing accounts for 95% of all processed electrodes, manual processing accounts for 5% of all processed electrodes, and only a very small number of special electrodes require manual replacement of tools. Therefore, a variety of tool magazines are used to configure the tools of CNC machine tools to increase the proportion of automated processing of electrodes, thereby improving the production and processing efficiency of the workshop, shortening the mold delivery time, and saving mold costs.
