Description

Technical Field

[0001] This document relates to the field of wire electrical discharge machining, and particularly to a method and apparatus for detecting the working conditions of a wire electrical discharge machine tool, as well as a computer-readable medium. Background Art

[0002] Wire electrical discharge machining, abbreviated as WEDM, belongs to the category of non-traditional machining. Different from traditional machining methods that require mechanical force and mechanical energy to cut workpieces, WEDM mainly uses electro-corrosion to machine materials. The factors affecting the machining speed of WEDM mainly include: machining process parameters, workpiece material, concentration and flow rate of cutting fluid, machining process route, and environmental temperature, etc. This makes it impossible to accurately estimate the time required to complete the cutting of a piece of material. Generally, the machining time of WEDM is relatively long, and it is impossible for people to stay beside it all the time to watch the cutting progress. It is also inconvenient to observe when machining some small materials. Most of the existing wire electrical discharge machine tools only display the machining progress on the computer system interface and display the corresponding interface after machining is completed. This method is not very intuitive and requires people to observe constantly. Summary of the Invention

[0050] In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the following will clearly and completely describe the technical solutions in one or more embodiments of this specification in conjunction with the drawings in one or more embodiments of this specification. Obviously, the described embodiments are only some of the embodiments of this specification, rather than all of them. Based on one or more embodiments of this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this document.

[0051] The embodiments of this specification provide a method for detecting the working condition of a wire electrical discharge machining cutting machine, as Figure 1 shown, including the following steps:

[0052] Step 1: Collect the image of the rocking wheel.

[0053] In the embodiment of the present application, the image of the rocking wheel can be captured by a conventional camera. For a scene with a dim processing environment, such as night processing, the image of the rocking wheel can be collected by means of low-light imaging. The collection frequency is defaulted to 1 frame / second.

[0054] Step 2: Determine the motion state information of the rocking wheel according to the rocking wheel image.

[0055] In the embodiment of the present application, the rocking wheel is provided with a position identifier, and the position identifier can be a pattern, text, protrusion or even a separately provided component. Preferably, a position identifier is set at a non-rotating center part of the rocking wheel. Specifically, as Figure 2 shown, a rocking handle is provided on the rocking wheel. In this way, the position change of the rocking handle in the image can be observed, so as to determine whether the rocking wheel rotates. When determining the position of the rocking handle, the corresponding position in the world coordinate system is obtained by calibrating the position of the rocking handle in the image coordinate system. The calibration method selects a simple linear calibration algorithm. The relationship between the coordinates (u, v) of the P point in the two-dimensional image coordinate system and the coordinates (X_w, Y_w, Z_w) in the world coordinate system is as follows:

[0056]

[0057] After setting the position identifier, the motion state information of the rocking wheel can be determined according to the position of the position identifier in the rocking wheel image. Specifically, according to the position of the position identifier in the rocking wheel image, it is determined whether the rocking wheel rotates within a preset period; the non-rotating duration is recorded; when the non-rotating duration exceeds the preset value, it is determined that the rocking wheel is in a stationary state; when the non-rotating duration does not exceed the preset value, it is determined that the rocking wheel is in a motion state.

[0058] In the embodiment of the present application, the preset value is the shooting time corresponding to shooting 5 frames of images.

[0059] Step 3: Determine the processing process information according to the motion state information of the rocking wheel.

[0060] In the embodiment of the present application, the completion thresholds for each processing direction are preset in advance, and each processing direction corresponds to a rocking wheel; the processing process information includes the number of completed processes in each processing direction, and the number of completed processes is used to characterize the processing progress in each processing direction. According to the motion state information of the rocking wheel corresponding to each processing direction, the number of completed processes in each case is determined.

[0061] Specifically, when machining a planar quadrilateral, at least two machining operations are required in the y direction, that is, two processes; and one machining operation is required in the x direction, that is, one process. At this time, the completion threshold in the y direction can be set to 2, and the completion threshold in the x direction can be set to 1. For each completed process, the number of processes in the corresponding direction is incremented by 1.

[0062] The specific process of determining the number of processes is as follows:

[0063] When the corresponding rocker state in the first direction is continuous movement, and the corresponding rocker state in the second direction changes from static to movement, the number of processes completed in the first direction +1;

[0064] When the corresponding rocker state in the first direction is continuous movement, and the corresponding rocker state in the second direction changes from continuous movement to static, the number of processes completed in the first direction +1, and the number of processes completed in the second direction +1;

[0065] When the corresponding rocker state in the first direction is static, and the corresponding rocker state in the second direction is static, the number of processes completed in the first direction +1 and / or the number of processes completed in the second direction +1.

[0066] For the sake of convenience, taking the processing of two-dimensional products as an example to illustrate the process of determining the number of processes, as Figure 3 shown, where the product is the area enclosed by line 12, line 23, line 34, and line 41, and line 23 is an arc. It can be seen from the figure that line 12, line 23, and line 34 each correspond to one process. The processing directions are set as the x-direction and the y-direction, where line 12 and line 34 are parallel to the y-axis, and line 41 is parallel to the x-axis.

[0067] When the processing starts, the number of processes completed in the x-direction and the y-direction is [0, 0].

[0068] Start processing along line 12. At this time, the corresponding rocker state in the y-direction is continuous movement. When line 12 is completed and line 23 starts to be processed, the corresponding rocker state in the y-direction is continuous movement, and the corresponding rocker state in the x-direction changes from static to movement. Then the number of processes completed in the y-direction +1. At this time, the number of processes completed in the x-direction and the y-direction is [0, 1].

[0069] After that, process along line 23. At this time, the corresponding rocker state in the y-direction is continuous movement, and the corresponding rocker state in the x-direction is continuous movement. When line 23 is completed and line 34 starts to be processed, the corresponding rocker state in the y-direction is continuous movement, and the corresponding rocker state in the x-direction changes from continuous movement to static. Line 23 is a curve, and processing a curve requires simultaneous processing in the x-direction and the y-direction. Then the number of processes completed in the y-direction +1, and the number of processes completed in the x-direction +1. At this time, the number of processes completed in the x-direction and the y-direction is [1, 2].

[0070] Finally, process along line 34. At this time, the corresponding rocker state in the y-direction is continuous movement, and the corresponding rocker state in the x-direction is static. When line 34 is completed, the corresponding rocker state in the y-direction changes from continuous movement to static. Then the number of processes completed in the y-direction +1. At this time, the number of processes completed in the x-direction and the y-direction is [1, 3].

[0071] It should be noted that technicians can also, according to the actual situation, after all processes are completed, increase the number of completed processes in both the x - direction and the y - direction by 1 to distinguish whether all are completed.

[0072] Step 4: Determine whether the processing is completed according to the processing process information and give corresponding prompts.

[0073] In the embodiment of the present application, in order not to mistake a machine failure for completion and to confirm the progress of the process when a machine failure occurs, when the number of completed processes in each processing direction reaches the corresponding completion threshold, it is determined that the processing is completed; otherwise, it is determined that the processing is not completed. The prompting methods include but are not limited to ringing, voice, and lighting.

[0074] Specifically, as Figure 3 shown, the completion threshold in the x - direction is 1, and the completion threshold in the y - direction is 3. Then, when the number of completed processes in the x - direction and the y - direction is [1, 3], it is determined that the processing is ended.

[0075] The embodiment of the present application provides a working condition detection device for a wire - cut electric discharge machine, including: a collection module, an image - processing module, and a data - processing module;

[0076] The collection module is used to collect images of the rocking wheel;

[0077] The image - processing module is used to determine the motion state information of the rocking wheel according to the rocking - wheel image;

[0078] The data - processing module is used to determine the processing process information according to the motion state information of the rocking wheel; determine whether the processing is completed according to the processing process information and give corresponding prompts.

[0079] In the embodiment of the present application, the processing directions include: the first direction and the second direction;

[0080] The data - processing module is used to, when the rocking - wheel state corresponding to the first direction is continuous motion and the rocking - wheel state corresponding to the second direction changes from static to motion, increase the number of completed processes in the first direction by 1; when the rocking - wheel state corresponding to the first direction is continuous motion and the rocking - wheel state corresponding to the second direction changes from continuous motion to static, increase the number of completed processes in the first direction by 1 and increase the number of completed processes in the second direction by 1; when the rocking - wheel state corresponding to the first direction is static and the rocking - wheel state corresponding to the second direction is static, increase the number of completed processes in the first direction by 1 and / or increase the number of completed processes in the second direction by 1.

[0081] The embodiment of the present application provides a storage medium, including:

[0082] For storing computer-executable instructions which, when executed, implement the following process:

[0083] Collect an image of the rocking wheel;

[0084] Determine the motion state information of the rocking wheel according to the rocking wheel image;

[0086] Determine whether the work is completed according to the processing process information and give corresponding prompts.

[0087] The specific embodiments of this specification have been described above. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve the desired results. Additionally, the processes depicted in the figures do not necessarily require the particular order or sequential order shown to achieve the desired results. In certain embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0088] In the 1930s, improvements to a technology could be clearly distinguished as either hardware improvements (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software improvements (improvements to method flows). However, with the development of technology, many method flow improvements today can be regarded as direct improvements to hardware circuit structures. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement to a method flow cannot be implemented using a hardware entity module. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is an integrated circuit whose logical function is determined by the user programming the device. Designers can program themselves to "integrate" a digital system onto a single PLD, without having to ask a chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compilers used in program development and writing. The original code before compilation also has to be written in a specific programming language, which is called a Hardware Description Language (HDL), and there is not just one type of HDL, but many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones currently are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be aware that by simply performing a little logical programming on the method flow using the above-mentioned several hardware description languages and programming it into an integrated circuit, it is easy to obtain the hardware circuit that implements the logical method flow.

[0089] The controller can be implemented in any suitable manner. For example, the controller can take the form of, for example, a microprocessor or a processor and a computer-readable medium storing computer-readable program code (such as software or firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of the controller include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that, in addition to implementing the controller in the form of pure computer-readable program code, it is entirely possible to make the controller implement the same function in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be regarded as the structures within the hardware component. Or even, the devices for implementing various functions can be regarded as either software modules for implementing the method or the structures within the hardware component.
