Description

Technical Field

[0001] This invention relates to the field of grooving machine technology, and more particularly to an electrical control system and method for detecting tool wear in grooving machines. Background Technology

[0002] A grooving machine is a machine tool used for metal processing. It is mainly used to cut grooves of specific shapes on metal sheets. Before bending the metal sheet, the grooving machine cuts V-shaped or U-shaped grooves on the part of the sheet that needs to be bent.

[0003] However, existing grooving machines generally have two ways to detect cutter head wear. One is to measure the formed sheet to confirm whether the cutter needs to be re-set or replaced, but this method will scrap a sheet. The other is to re-set the cutter every once in a while, but this will result in low work efficiency.

[0004] To address the aforementioned problems, this invention adds a tool wear detection device to the grooving machine, which can perform touch detection on each tool; when a tool is worn, it is directly compensated, avoiding the need for re-calibration. This device improves work efficiency and avoids waste of sheet metal. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art and provide an electrical control system and method for detecting tool wear in a grooving machine.

[0006] The technical solution of the present invention is: an electrical control system for detecting tool wear of a grooving machine, comprising a grooving machine body, on which a Z-axis linear module, a W-axis linear module and a P-axis linear module for providing power are installed;

[0007] Three cutters are mounted on the output sliders of both the Z-axis and W-axis linear modules. The height and installation position of the three cutters on the Z-axis and W-axis are different, with each cutter differing by a few millimeters. The first cutter is at the highest position, and the third cutter is at the lowest position. The third cutter is the final position that determines the groove depth. Therefore, the cutter compensation value can only be set based on the third cutter.

[0008] It also includes the following components;

[0009] The motion controller transforms predetermined control schemes and planning instructions into desired mechanical motion, achieving precise command control. The motion controller is electrically connected to the Z-axis linear module, W-axis linear module, and P-axis linear module.

[0010] A human-machine interface (HMI) is used to display text or graphics and has user input functionality to enable information interaction between humans and machines. The HMI is used to receive instruction information sent by the motion controller and upload user demand information to the motion controller. The motion controller is electrically connected to the HMI.

[0011] The tool setter is used to detect the quality of the tool and upload the tool detection results to the judgment module. The tool setter is fixedly installed on the output slider of the P-axis linear module.

[0012] The tri-color light is used to receive command information from the motion controller and to intuitively display the detection results of the tool. The tri-color light is electrically connected to the motion controller.

[0013] The judgment module is used to receive the tool detection results from the motion controller and determine whether the error range of the tool is within the system's set range. The judgment module uploads the judgment results to the motion controller, which receives the tool judgment results and controls the three-color lights to light up according to the tool judgment results.

[0014] The alarm module is used to receive alarm commands from the motion controller. The alarm module is electrically connected to the motion controller.

[0015] The tool compensation module is used to receive the tool judgment result from the judgment module, calculate the tool compensation value, and upload it to the motion controller.

[0016] The monitoring module is fixedly installed on the main body of the grooving machine, with the monitoring end facing the Z-axis linear module, W-axis linear module and P-axis linear module. It is used to monitor the position information of the Z-axis linear module, W-axis linear module and P-axis linear module.

[0017] Furthermore, the Z-axis linear module includes a Z-axis driver and a Z-axis motor. Both the Z-axis driver and the Z-axis motor are fixedly mounted on the main body of the grooving machine. The output end of the Z-axis driver is fixedly connected to the drive end of the Z-axis motor, and the motion controller is electrically connected to the Z-axis driver.

[0018] Furthermore, the W-axis linear module includes a W-axis driver and a W-axis motor. Both the W-axis driver and the W-axis motor are fixedly mounted on the main body of the grooving machine. The output end of the W-axis driver is fixedly connected to the drive end of the W-axis motor, and the motion controller is electrically connected to the W-axis driver.

[0019] Furthermore, the P-axis linear module includes a P-axis driver and a P-axis motor. Both the P-axis driver and the P-axis motor are fixedly mounted on the grooving machine body. The output end of the P-axis driver is fixedly connected to the drive end of the P-axis motor, and the motion controller is electrically connected to the P-axis driver.

[0020] Furthermore, the tri-color light includes a red light, a green light, and a yellow light;

[0021] The control method for red, green, and yellow lights is as follows: if the judgment module detects that the errors of the three tools on the Z-axis and the three tools on the W-axis are both within the system setting range and no tool compensation is required, then the green light will illuminate.

[0022] If the judgment module detects that the errors of the three tools on the Z-axis and the three tools on the W-axis are both within the system setting range, but tool compensation is required, then the yellow light will illuminate.

[0023] If the judgment module detects that the error of the three tools on the Z-axis or any one of the three tools on the W-axis is outside the error range set by the system, the red light will illuminate.

[0024] Furthermore, the judgment method of the judgment module is as follows:

[0025] If the error values ​​of the three Z-axis tools and the three W-axis tools are all within the range set by the system, the judgment module will upload the error values ​​of the three Z-axis tools and the three W-axis tools to the tool compensation module to calculate the tool compensation value of the corresponding tool.

[0026] If the error value of any one of the three tools on the Z-axis or the three tools on the W-axis is outside the range set by the system, the judgment module will upload the judgment result to the motion controller. The motion controller will then send an IO signal to the three-color light, the red light will light up, and the motion controller will control the alarm module to sound an alarm. The motion controller will upload the position and error value of the corresponding tool to the human-machine interface and display it, reminding the operator to change the tool.

[0027] Furthermore, the alarm module is a buzzer.

[0028] Furthermore, the monitoring module is a high-definition camera.

[0029] To better achieve the objectives of this invention, this invention also provides a method for detecting tool wear on a grooving machine, comprising the following steps:

[0030] Step 1: The motion controller sends a pulse command to the P-axis linear module. The output slider of the P-axis linear module starts to drive the tool setter to move to the left. When the monitoring module detects that the tool setter has moved to point F, the monitoring module uploads the position information of the tool setter to the motion controller. The motion controller then commands the P-axis linear module to stop moving.

[0031] Step 2: The motion controller sends a pulse command to the Z-axis linear module. The output slider of the Z-axis linear module drives the three Z-axis tools to start moving downward. When the first Z-axis tool touches the sensing plane on the tool setting device, the tool setting device sends a signal to the motion controller. Upon receiving the signal, the motion controller commands the Z-axis linear module to stop moving.

[0032] Step 3: The motion controller confirms the error value of the first tool on the Z-axis based on the stop position of the slider output by the Z-axis linear module and the position of the tool setter;

[0033] Step 4: Move the tool setter to points E and D in sequence, repeat the above steps to check the other two tools on the Z-axis and determine the error values ​​of the other two tools on the Z-axis.

[0034] Step 5: The tool setter moves to point C. The motion controller sends a pulse command to the W-axis linear module. The output slider of the W-axis linear module drives the three tools on the W-axis to move downward. When the first tool on the W-axis touches the sensing plane on the tool setter, the tool setter sends a signal to the motion controller. Upon receiving the signal, the motion controller commands the W-axis linear module to stop moving. The motion controller confirms the error value of the first tool on the W-axis based on the stop position of the output slider of the W-axis linear module and the position of the tool setter.

[0035] The tool setter is moved to points B and A in sequence. The above steps are repeated to check the other two tools on the W-axis and determine the error values ​​of the other two tools on the W-axis.

[0036] Step 6: The motion controller uploads the error values ​​of the three tools on the Z-axis and the three tools on the W-axis to the judgment module for error range judgment;

[0037] Step 7: The judgment module uploads the judgment results of the three tools on the Z-axis and the three tools on the W-axis to the motion controller and the tool compensation module. The motion controller controls the three-color lights to light up according to the judgment results.

[0038] Step 8: The tool compensation module receives the error values ​​of the third tool on the Z-axis and the third tool on the W-axis from the judgment module, and then calculates the tool compensation values ​​of the third tool on the Z-axis and the third tool on the W-axis. The tool compensation value = the tool error value. After that, the tool compensation module inputs the tool compensation values ​​of the third tool on the Z-axis and the third tool on the W-axis into the motion controller.

[0039] Step 9: The motion controller receives the tool compensation values ​​of the third tool of the Z-axis and the third tool of the W-axis and sends pulse commands to the Z-axis linear module and the W-axis linear module. The output slider of the Z-axis linear module drives the three tools of the Z-axis to start moving downward. When the downward movement of the three tools of the Z-axis is equal to the tool compensation value of the third tool of the Z-axis, the motion controller controls the Z-axis linear module to stop.

[0040] The output slider of the W-axis linear module drives the three tools of the W-axis to start moving downward. When the downward movement of the three tools of the W-axis is equal to the tool compensation value of the third tool of the W-axis, the motion controller controls the W-axis linear module to stop.

[0041] Step 10: Compensation for the three tools on the Z-axis and the three tools on the W-axis is completed.

[0042] In use, the motion controller sends control commands to the P-axis linear module. The P-axis linear module controls the tool setter to move to the commanded position to detect the tool. The tool setter then uploads the detection results to the judgment module. The judgment module determines whether the detection results at multiple points are within the system's error range. If they are within the error range, the judgment module uploads the judgment results to the tool compensation module, causing the motion controller to control the Z-axis linear module or the W-axis linear module to compensate for the tool. If they are not within the error range, the judgment module uploads the judgment results to the motion controller, which then controls the tri-color indicator and alarm module to sound an alarm.

[0043] This invention enables touch detection of each tool through a tool setting device, and can compensate the tool based on the detection results to avoid re-setting the tool. This device improves work efficiency, avoids waste of sheet metal, and realizes the functions of monitoring, compensating for and alarming worn tools. Attached Figure Description

[0055] Three cutters are installed on the output sliders of the Z-axis linear module 4 and the W-axis linear module 5. The height and installation position of the three cutters on the Z-axis and W-axis are different, with each cutter differing by 15 microns. The first cutter is at the highest position, and the third cutter is at the lowest position. The third cutter is the final position that determines the groove depth. Therefore, the cutter compensation value can only be set based on the third cutter.

[0056] It also includes the following components;

[0057] Motion controller 2 converts the predetermined control scheme and planning instructions into the desired mechanical motion, achieving precise command control. Motion controller 2 is electrically connected to Z-axis linear module 4, W-axis linear module 5, and P-axis linear module 6.

[0058] The Z-axis linear module 4 includes a Z-axis driver 41 and a Z-axis motor 42. Both the Z-axis driver 41 and the Z-axis motor 42 are fixedly installed on the grooving machine body 1.

[0061] Human-machine interface 3 is used for displaying text or graphics and has user input function to realize information interaction between humans and machines. Human-machine interface 3 is used to receive instruction information sent by motion controller 2 and upload user demand information to motion controller 2. Motion controller 2 is electrically connected to human-machine interface 3.

[0062] Tool setter 7 is used to detect the quality of the tool and upload the tool detection results to the judgment module 10. Tool setter 7 is fixedly installed on the output slider of P-axis linear module 6.

[0063] Preferably, the tool setter 7 is a TP-300HB contact tool setter, which is suitable for tool setting and pre-adjustment.

[0064] The tri-color light 8 is used to receive instruction information from the motion controller 2 and to intuitively display the detection results of the tool. The tri-color light 8 is electrically connected to the motion controller 2.

[0065] Preferably, the tri-color light 8 includes a red light 81, a green light 82, and a yellow light 83;

[0066] The control method for red light 81, green light 82 and yellow light 83 is as follows: if the judgment module 10 detects that the errors of the three tools on the Z-axis and the three tools on the W-axis are both within the system setting range and no tool compensation is required, then green light 82 will light up.

[0067] If the judgment module 10 detects that the errors of the three tools on the Z-axis and the three tools on the W-axis are both within the system setting range, but tool compensation is required, then the yellow light 83 will light up.

[0068] If the judgment module 10 detects that the error of the three tools on the Z-axis or any one of the three tools on the W-axis is outside the error range set by the system, then the red light 81 will light up.

[0069] The judgment module 10 is used to receive the tool detection result in the motion controller 2 and determine whether the error range of the tool is within the system's set range. The judgment module 10 uploads the judgment result to the motion controller 2. The motion controller 2 receives the tool judgment result and controls the tri-color light 8 to light up according to the tool judgment result.

[0070] Preferably, the judgment method of the judgment module 10 is as follows:

[0071] If the error values ​​of the three tools on the Z-axis and the three tools on the W-axis are all within the range set by the system, the judgment module 10 will upload the error values ​​of the three tools on the Z-axis and the three tools on the W-axis to the tool compensation module 11 to calculate the tool compensation value of the corresponding tool.

[0072] If the error value of any one of the three tools on the Z-axis or the three tools on the W-axis is outside the range set by the system, the judgment module 10 will upload the judgment result to the motion controller 2. The motion controller 2 will then send an IO signal to the three-color light 8, and the red light 81 will light up. The motion controller 2 will also control the alarm module 9 to sound an alarm. The motion controller 2 will upload the position and error value of the corresponding tool to the human-machine interface 3 and display it to remind the operator to change the tool.

[0073] Alarm module 9 is used to receive alarm instructions from motion controller 2. Alarm module 9 is electrically connected to motion controller 2.

[0074] Preferably, the alarm module 9 is a buzzer.

[0075] The tool compensation module 11 is used to receive the tool judgment result from the judgment module 10, calculate the tool compensation value, and upload it to the motion controller 2;

[0076] The monitoring module 12 is fixedly installed on the main body 1 of the grooving machine, with the monitoring end facing the Z-axis linear module 4, W-axis linear module 5 and P-axis linear module 6. It is used to monitor the position information of the Z-axis linear module 4, W-axis linear module 5 and P-axis linear module 6.

[0077] Preferably, the monitoring module 12 is a high-definition camera.

[0078] In use, the motion controller 2 sends a control command to the P-axis linear module 6. The P-axis linear module 6 controls the tool setter 7 to move to the commanded position to detect the tool. The tool setter 7 then uploads the detection results to the judgment module 10. The judgment module 10 determines whether the detection results of multiple points are within the system's error range. If they are within the error range, the judgment module 10 uploads the judgment results to the tool compensation module 11, so that the motion controller 2 controls the Z-axis linear module 4 or the W-axis linear module 5 to compensate the tool. If they are not within the error range, the judgment module 10 uploads the judgment results to the motion controller 2, and the motion controller 2 controls the tri-color light 8 and the alarm module 9 to sound an alarm.

[0079] This invention enables touch detection of each tool through the tool setting device 7, and can compensate the tool according to the detection results to avoid re-setting the tool. This device not only improves work efficiency, but also avoids waste of sheet metal, and realizes the functions of monitoring, compensating and alarming worn tools.

[0080] Example 2: In some embodiments, such as Figures 1-2 As shown, in a preferred embodiment of the present invention, the grooving machine body 1 is tested when it is turned on, and the tool setter 7 tests a total of 6 tools on the Z-axis and W-axis.

[0081] A method for detecting wear on grooving machine cutting tools includes the following steps:

[0082] Step 1: Motion controller 2 sends a pulse command to P-axis linear module 6. The output slider of P-axis linear module 6 starts to drive tool setter 7 to move to the left. When monitoring module 12 detects that tool setter 7 has moved to point F, monitoring module 12 uploads the position information of tool setter 7 to motion controller 2. Motion controller 2 then commands P-axis linear module 6 to stop moving.

[0083] Step 2: Motion controller 2 sends a pulse command to Z-axis linear module 4. The output slider of Z-axis linear module 4 drives the three Z-axis tools to start moving downward. When the first Z-axis tool touches the sensing plane on the tool setting device 7, the tool setting device 7 sends a signal to motion controller 2. Motion controller 2 receives the signal and commands Z-axis linear module 4 to stop moving.

[0084] Step 3: The motion controller 2 confirms the error value of the first tool on the Z-axis based on the stop position of the slider output by the Z-axis linear module 4 and the position of the tool setter 7;

[0085] Step 4: Move the tool setter 7 to points E and D in sequence, repeat the above steps to check the other two tools on the Z-axis and determine the error values ​​of the other two tools on the Z-axis.

[0086] Step 5: The tool setter 7 moves to point C. The motion controller 2 sends a pulse command to the W-axis linear module 5. The output slider of the W-axis linear module 5 drives the three tools on the W-axis to start moving downward. When the first tool on the W-axis touches the sensing plane on the tool setter 7, the tool setter 7 sends a signal to the motion controller 2. Upon receiving the signal, the motion controller 2 commands the W-axis linear module 5 to stop moving. The motion controller 2 confirms the error value of the first tool on the W-axis based on the stop position of the output slider of the W-axis linear module 5 and the position of the tool setter 7.

[0087] The tool setter 7 is moved to positions B and A in sequence. The above steps are repeated to check the other two tools on the W axis and determine the error values ​​of the other two tools on the W axis.

[0088] Step 6: Motion controller 2 uploads the error values ​​of the three tools on the Z-axis and the three tools on the W-axis to the judgment module 10 for error range judgment;

[0089] Step 7: The judgment module 10 uploads the judgment results of the three tools on the Z-axis and the three tools on the W-axis to the motion controller 2 and the tool compensation module 11. The motion controller 2 controls the three-color light 8 to light up according to the judgment results.

[0090] Step 8: The tool compensation module 11 receives the error values ​​of the third tool of the Z-axis and the third tool of the W-axis from the judgment module 10, and then calculates the tool compensation value of the third tool of the Z-axis and the third tool of the W-axis. The tool compensation value = the tool error value. After that, the tool compensation module 11 inputs the tool compensation value of the third tool of the Z-axis and the third tool of the W-axis into the motion controller 2.

[0091] Step 9: Motion controller 2 receives the tool compensation values ​​of the third tool of the Z-axis and the third tool of the W-axis and sends pulse commands to the Z-axis linear module 4 and the W-axis linear module 5. The output slider of the Z-axis linear module 4 drives the three tools of the Z-axis to start moving downward. When the downward movement of the three tools of the Z-axis is equal to the tool compensation value of the third tool of the Z-axis, the motion controller 2 controls the Z-axis linear module 4 to stop.

[0092] The output slider of the W-axis linear module 5 drives the three tools of the W-axis to start moving downward. When the length of the downward movement of the three tools of the W-axis is equal to the tool compensation value of the third tool of the W-axis, the motion controller 2 controls the W-axis linear module 5 to stop.

[0093] Step 10: Compensation for the three tools on the Z-axis and the three tools on the W-axis is completed.

[0094] Example 3: Figure 3 As shown, in a preferred embodiment of the present invention, when the grooving machine body 1 is running, a time variable is set in the motion controller 2. When the grooving machine body 1 is running for a period of time, a test is performed. Only the tool setter 7 needs to test the third tool of the Z-axis and W-axis.

[0095] There are two reasons for testing the third knife:

[0096] Firstly, there's the issue of wear. Because the three blades on the Z and W axes of the grooving machine body 1 are installed at different heights, with each blade differing by 15 micrometers, the first blade is at the highest position and the third blade at the lowest. During grooving, as the groove depth increases, the depth of each cut decreases, to the point that towards the end, only the third blade is actually cutting, making it the most subject to wear.

[0097] Secondly, there's the issue of efficiency. Each test takes time, and if the third blade doesn't need to be changed, then the other two blades don't need to be either.

[0098] If the tool setter 7 detects that the third tool needs to be replaced, place a tool setting block under the three tools, and then drive the corresponding Z-axis linear module 4 or W-axis linear module 5 to move the tool downwards to the observation position and contact the tool setting block. Observe the wear of the tool head with the naked eye. If the tool head is severely worn, replace it. This operation will save a lot of time.

[0099] The three knives correspond to three positions on the blade block, and the three positions differ by 15 micrometers, which corresponds exactly to the height of the three knives.

[0100] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes and modifications made in accordance with the scope of the claims of this invention should fall within the technical scope of this invention.

9. A method for detecting tool wear on a grooving machine, utilizing the electrical control system for detecting tool wear on a grooving machine as described in any one of claims 1-8, characterized in that, Includes the following steps: Step 1: The motion controller (2) sends a pulse command to the P-axis linear module (6). The output slider of the P-axis linear module (6) starts to drive the tool setter (7) to move to the left. When the monitoring module (12) detects that the tool setter (7) has moved to point F, the monitoring module (12) uploads the position information of the tool setter (7) to the motion controller (2). The motion controller (2) then commands the P-axis linear module (6) to stop moving. Step 2: The motion controller (2) sends a pulse command to the Z-axis linear module (4). The output slider of the Z-axis linear module (4) drives the three Z-axis tools to start moving downward. When the first Z-axis tool touches the sensing plane on the tool setting device (7), the tool setting device (7) sends a signal to the motion controller (2). The motion controller (2) receives the signal and commands the Z-axis linear module (4) to stop moving. Step 3: The motion controller (2) confirms the error value of the first tool on the Z-axis based on the stop position of the slider output by the Z-axis linear module (4) and the position of the tool setter (7); Step 4: Move the tool setter (7) to points E and D in sequence, repeat the above steps to check the other two tools on the Z-axis and determine the error values ​​of the other two tools on the Z-axis; Step 5: The tool setter (7) moves to point C. The motion controller (2) sends a pulse command to the W-axis linear module (5). The output slider of the W-axis linear module (5) drives the three tools of the W-axis to start moving downward. When the first tool of the W-axis touches the sensing plane on the tool setter (7), the tool setter (7) sends a signal to the motion controller (2). The motion controller (2) receives the signal and commands the W-axis linear module (5) to stop moving. The motion controller (2) confirms the error value of the first tool of the W-axis based on the stop position of the output slider of the W-axis linear module (5) and the position of the tool setter (7). The tool setter (7) moves to points B and A in sequence. The above steps are repeated to detect the other two tools of the W-axis and determine the error values ​​of the other two tools of the W-axis. Step 6: The motion controller (2) uploads the error values ​​of the three tools on the Z-axis and the three tools on the W-axis to the judgment module (10) for error range judgment; Step 7: The judgment module (10) uploads the judgment results of the three tools on the Z-axis and the three tools on the W-axis to the motion controller (2) and the tool compensation module (11). The motion controller (2) controls the three-color light (8) to light up according to the judgment results. Step 8: The tool compensation module (11) receives the error values ​​of the third tool of the Z-axis and the third tool of the W-axis from the judgment module (10), and then calculates the tool compensation value of the third tool of the Z-axis and the third tool of the W-axis. The tool compensation value = the tool error value. Then the tool compensation module (11) inputs the tool compensation value of the third tool of the Z-axis and the third tool of the W-axis into the motion controller (2). Step 9: The motion controller (2) receives the tool compensation values ​​of the third tool of the Z-axis and the third tool of the W-axis and sends pulse commands to the Z-axis linear module (4) and the W-axis linear module (5). The output slider of the Z-axis linear module (4) drives the three tools of the Z-axis to start moving downward. When the length of the downward movement of the three tools of the Z-axis is the tool compensation value of the third tool of the Z-axis, the motion controller (2) controls the Z-axis linear module (4) to stop. The output slider of the W-axis linear module (5) drives the three tools of the W-axis to start moving downward. When the length of the downward movement of the three tools of the W-axis is the tool compensation value of the third tool of the W-axis, the motion controller (2) controls the W-axis linear module (5) to stop. Step 10: Compensation for the three tools on the Z-axis and the three tools on the W-axis is completed.
