Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to an intelligent testing device and method based on CNC machine tool operation panel processing. Background Technology

[0002] The control panel of a CNC machine tool, as the core component of human-machine interaction, integrates numerous buttons (including round and rectangular buttons) and emergency stop knobs, among other control elements. During production, functional testing of the control panel is a crucial step in ensuring product quality.

[0003] Referring to patent application CN211136257U, a novel operating panel for machining equipment includes a machine tool body. The front of the machine tool body has a machining observation window, and a storage slot is located to the right of the observation window. The inner surfaces of the top and bottom of the storage slot are rotatably connected to the same rotating rod via bearing seats. A U-shaped mounting plate is fixedly connected to the right side of the rotating rod, and a return spring is fixedly connected to the inner surface of the left side of the U-shaped mounting plate. This invention uses the bearing seats and rotating rod to control the rotation angle of the operating panel body, and the return spring and force-applying handle to control and adjust the left and right positions of the operating panel body. This effective pulling and adjusting of the operating panel body improves operating efficiency and quality, thereby enhancing overall working accuracy.

[0004] The following problems exist during use: In existing testing equipment, the pressure head for circular buttons of different sizes on the control panel is mostly of a fixed diameter: if the diameter of the pressure head is larger than the key spacing, it is easy to touch adjacent buttons simultaneously when pressing down, causing false key misjudgment; if the diameter of the pressure head is smaller than the button size, it may not be able to reach the edge of the button, especially for large silicone buttons, after the center collapses, the small diameter pressure head cannot drive the entire keycap down, resulting in the contact not closing and a false fault of "no signal when pressed". Existing equipment lacks the ability to adjust the diameter of the pressure head in real time; as for the emergency stop knob, it usually requires a compound action of pressing and then rotating. Most existing equipment can only complete the pressing or rotating separately, and cannot continuously perform the "press-rotate" test at the same station. It often requires two clamping or two equipment to cooperate, which increases the cost and introduces secondary positioning error; and the clamping method of rigid claws is easy to scratch the surface of the knob, and has poor adaptability to knobs of different diameters and irregular shapes.

[0005] Therefore, it is necessary to provide an intelligent testing device and method based on CNC machine tool operation panel processing to solve the above-mentioned technical problems. Summary of the Invention

[0012] As a further embodiment of the present invention: the switching mechanism includes a guide frame, which is fixedly connected to the bottom of the fixed frame and is disposed outside the first fixed cylinder and the second fixed cylinder. Two guide grooves are provided on both sides of the guide frame, and the two guide grooves are symmetrically arranged.

[0013] As a further aspect of the present invention: the switching mechanism further includes two fixed frames, both of which are disposed inside the fixed frame, and two hydraulic push rods are fixedly connected inside the fixed frame. The telescopic ends of the two hydraulic push rods pass through the fixed frame and are fixedly connected to the first fixed cylinder and the second fixed cylinder respectively. A fixed rod is fixedly connected inside the fixed frame. A slider is fixedly connected to the top of the first fixed cylinder and the second fixed cylinder. The fixed rod passes through the slider and is slidably connected to the slider. A guide shaft is fixedly connected to the outside of the first fixed cylinder and the second fixed cylinder. The guide shaft extends into the guide groove and is slidably connected to the guide frame.

[0014] As a further aspect of the present invention: the clamping mechanism includes two second clamping plates and two first clamping plates, both of which extend into the interior of a fixed plate and are slidably connected to the fixed plate. The fixed plate is provided with two lead screws, which are respectively connected to the two first clamping plates and the two second clamping plates via ball nut pairs to drive the two first clamping plates to move relative to each other and the two second clamping plates to move relative to each other.

[0015] As a further aspect of the present invention: the clamping mechanism further includes multiple striking rods, each of which is disposed on one side of the second clamping plate and passes through the second clamping plate and is slidably connected to it.

[0016] A smart testing method based on CNC machine tool operation panel processing includes the following steps: Step 1: Place the control panel to be tested on top of the fixing plate and fix it with the clamping mechanism. At the same time, connect the connection wire of the control panel to the terminal. Step 2: The fixing plate is then transported to the inside of the fixing cover via the electric slide rail. The lifting module is activated to seal the fixing plate with the sealing cover. At the same time, the jet nozzle is connected to the external hot air pipe to ventilate the inside of the sealing cover. Step 3: Once the temperature reaches the set value, the combined module moves the fixed frame, and the test buttons on the operation panel are distinguished based on the monitoring of the recognition camera.

No manual intervention or fixture replacement is required. This design realizes continuous and automated testing of different key types, greatly shortens the testing cycle, and is suitable for online full inspection of batch production lines.

[0018] 2. It allows for precise control of the pressing range, ensuring the pressure head diameter is slightly smaller than the key size and does not exceed the keycap boundary, fundamentally eliminating false key presses. Simultaneously, the solidified magnetic fluid pressure head evenly covers the entire key surface, ensuring edge force even if the center of a large key collapses, achieving reliable triggering. Furthermore, the mechanism allows for continuous diameter adjustment without replacing the pressure head, making it suitable for automated testing of various sizes of circular keys on the same panel.

[0019] 3. By pressing down as a whole, the rectangular button is tested. A matching rectangular pressure head can press the entire length of the button at the same time, ensuring that the button moves down in parallel, the contact point makes reliable contact, and the button function is truly reflected. In addition, the adjustable rectangular pressure head can be expanded into a larger rectangular area, pressing a group of adjacent buttons at the same time, which greatly improves the testing efficiency. This is something that single-point or circular pressure heads cannot do.

[0020] 4. During rotation, monitor the output signal of the knob encoder or potentiometer through the terminal to determine whether its rotation function is normal. Integrate the pressing and rotation tests in the same station, eliminating the need to replace the actuator and improving testing efficiency. At the same time, the second flexible bladder before curing can adaptively wrap knobs of different diameters and shapes. After curing, it can transmit sufficient torque without scratching the knob surface. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0026] like Figures 1 to 10 As shown, an intelligent testing device and method based on CNC machine tool operation panel processing includes the following embodiments: Example 1: Includes a detection base 1, with a fixing cover 101 fixedly connected to the top of the detection base 1, and further includes: An electric slide rail 2 for horizontal movement is fixedly connected to the top of the detection base 1, and a fixed plate 201 is fixedly connected to the moving end of the electric slide rail 2. A clamping mechanism for fixing the operation panel is provided on the top of the fixed plate 201, and a terminal 10 for wiring the operation panel is fixedly connected to the top of the fixed plate 201. A lifting module 4 for vertical movement is fixedly connected to the top of the detection base 1, and a sealing cover 5 is fixedly connected to the lifting end of the lifting module 4. A jet nozzle 501 for introducing hot air is fixedly connected to the top of the sealing cover 5. A combination module 502 is set inside the sealing cover 5. A fixing frame 6 is fixedly connected to the moving end of the combination module 502. The combination module 502 is combined with a lifting shaft and an XY axis, which is the prior art. A first fixing cylinder 7 and a second fixing cylinder 8 are set inside the fixing frame 6. A pressing mechanism for button testing is set inside the first fixing cylinder 7. A rotating mechanism for rotary key testing is set inside the second fixing cylinder 8. An identification camera 600 for identifying panel test pieces is set inside the fixing frame 6. A switching mechanism for switching between the first fixing cylinder 7 and the second fixing cylinder 8 according to the button type is set inside the fixing frame 6.

[0027] In practice, the control panel to be tested is placed on top of the fixed plate 201 and fixed by the clamping mechanism, while the connecting wire of the control panel is connected to the terminal 10. Then, the fixed plate 201 is transported into the fixed cover 101 by the electric slide rail 2, and the lifting module 4 is activated to lower the sealing cover 5 to seal the fixed plate 201. The jet nozzle 501 is connected to the external hot air pipeline to introduce hot air into the sealing cover 5. When the temperature inside the sealing cover 5 reaches the set value, the combination module 502 drives the fixed frame 6 to move, and the recognition camera 600 is used to scan the control panel. The test keys on the control panel are identified and distinguished. Finally, the first fixed cylinder 7 or the second fixed cylinder 8 is selected by the switching mechanism to press or rotate the corresponding test keys to determine whether their functions are normal. The recognition camera 600 automatically distinguishes the test key types on the control panel, such as ordinary press keys and rotary encoder keys, and quickly selects the corresponding first fixed cylinder 7 or the second fixed cylinder 8 for testing through the switching mechanism. No manual intervention or fixture replacement is required. This design realizes continuous and automated testing of different key types, greatly shortens the testing cycle, and is suitable for online full inspection of mass production lines. During the test, the jet head 501 continuously introduces hot air into the sealed cover 5. Compared with the normal temperature test, the high temperature environment can effectively expose potential faults caused by thermal expansion, material softening or electrical parameter drift, making the test results closer to the real use scenario and significantly reducing the early failure rate after the product leaves the factory.

[0028] Example 2: The pressing mechanism includes a first pressure plate 702, which is disposed inside the first fixed cylinder 7 and is slidably connected to the inner wall of the first fixed cylinder 7. A first electric push rod 704 is fixedly connected to the top of the first fixed cylinder 7. The telescopic end of the first electric push rod 704 is fixedly connected to the first pressure plate 702. A first flexible bladder 701 is fixedly connected to the bottom of the first pressure plate 702. The first flexible bladder 701 is filled with magnetic fluid. A first electromagnet 703 is fixedly connected to the top of the first pressure plate 702. When the first electromagnet 703 is energized, the magnetic fluid inside the first flexible bladder 701 is solidified.

[0029] The pressing mechanism also includes a through groove 705 at the bottom of the first fixed cylinder 7. The first flexible bladder 701 extends into the through groove 705. A fixing ring 706 is fixedly connected to the bottom of the first fixed cylinder 7. The fixing ring 706 is coaxially arranged with the through groove 705, and the radius of the fixing ring 706 is larger than that of the through groove 705. An air bladder 707 is fixedly connected to the inner side of the fixing ring 706. A micro air pump is provided on the outer side of the first fixed cylinder 7. The micro air pump is connected to the air bladder 707 through a connecting pipe. The air bladder 707 inflates after being inflated.

[0030] In practical implementation, during actual testing, the control panel may contain circular buttons of varying sizes. If the pressure head diameter is larger than the key spacing, adjacent buttons may be pressed simultaneously, causing misjudgment of key overlap; if the pressure head diameter is too small, it may fail to reach the edge of the button, especially when the central area of ​​a large silicone button collapses, leading to pressing failure. To solve the above problems, this solution designs the following adjustable pressing mechanism: The first electric actuator 704 inside the first fixed cylinder 7 is activated, pushing the first pressure plate 702 downward to compress the first flexible bladder 701. The magnetic fluid filling the first flexible bladder 701, after being compressed, flows into the fixed ring 706 through the through groove 705. Simultaneously, a micro air pump is activated, inflating the air bladder 707 through the connecting pipe. The air bladder 707 expands and contracts its radius inward, thereby creating a radial constraint on the magnetic fluid area squeezed out from the through groove 705, limiting the diameter of the downward protrusion of the first flexible bladder 701. By adjusting the inflation amount of the air bladder 707, the diameter of the protruding disc can be continuously controlled, making it slightly smaller than the size of the button being tested. Once the protrusion diameter is adjusted to the correct position, the first electromagnet 703 is energized, generating a magnetic field that instantly solidifies the magnetic fluid inside the first flexible capsule 701, forming a rigid pressure head that matches the button size. Subsequently, the combined module 502 lowers the fixing frame 6 as a whole, causing the solidified first flexible capsule 701 to press the button. During the pressing process, the electrical signal of the button is monitored in real time via the wiring terminal 10 to ensure normal continuity. It allows for precise control of the pressing range, ensuring the pressure head diameter is slightly smaller than the key size and does not exceed the keycap boundary, fundamentally eliminating false key presses. Simultaneously, the solidified magnetic fluid pressure head evenly covers the entire key surface, ensuring edge force even if the center of a large key collapses, achieving reliable triggering. Furthermore, the mechanism allows for continuous diameter adjustment without replacing the pressure head, making it suitable for automated testing of various sizes of circular keys on the same panel.

[0031] The magnetorheological fluid used is a homogeneous mixture of micron- or nano-sized ferromagnetic particles such as Fe3O4 (iron oxide), surfactants, and a base liquid such as silicone oil or mineral oil. In the absence of an external magnetic field, the magnetic particles are randomly suspended in the base liquid, and the magnetorheological fluid as a whole exhibits a certain degree of fluidity, either liquid or viscous, and can freely deform under external forces.

[0032] In this embodiment, a movable disk 9 is provided at the bottom of the first fixed cylinder 7, and four limiting plates 903 are provided at the bottom of the movable disk 9. Four fourth electric push rods 904 are fixedly connected to the bottom of the movable disk 9. The telescopic ends of the four fourth electric push rods 904 are fixedly connected to the limiting plates 903. Each of the four limiting plates 903 has a guide frame 902 at one adjacent end, and the limiting plate 903 extends into the guide frame 902 and slides with it. The four limiting plates 903 and the four guide frames 902 form a rectangle. Multiple third push rods 901 are fixedly connected to the outside of the first fixed cylinder 7, and the telescopic ends of the third push rods 901 are fixedly connected to the movable disk 9.

[0033] In practical implementation, many control panels have long, thin function keys such as "Start / Stop," "Increase / Decrease," or navigation keys. If one end of the long, rectangular button is pressed with a single point or a circular pressure head, the button will tilt like a seesaw, with the other end lifting up, causing the internal conductive contacts to fail to close, resulting in a "failure" test result. However, the function works normally when the user actually presses the middle with their finger. Therefore, the solution uses a movable disk 9 at the bottom of the fixed ring 706. Based on the size of the rectangular button, four fourth electric actuators 904 are activated. The fourth electric actuators 904 drive the limiting plates 903 to move, causing the four limiting plates 903 and the four guide frames 902 to contract or expand. When the first pressure plate 702 continuously presses the first flexible bladder 701, the first flexible bladder 701, through the... The groove 705 enters the limiting frame formed by the limiting plate 903 and the guide frame 902, causing the first flexible bladder 701 to deform into a shape that conforms to the size of the button. Then, by pressing down as a whole, the rectangular button is tested. A matching rectangular pressure head can press the entire length of the button at the same time, ensuring that the button moves down in parallel, the contact point makes reliable contact, and the button function is truly reflected. Moreover, the adjustable rectangular pressure head can be expanded into a larger rectangular area, allowing a group of adjacent buttons, such as the up / down / left / right arrow keys or the 1-2-3 numeric keypad, to be pressed at the same time, which greatly improves the testing efficiency. This is something that single-point or circular pressure heads cannot do.

[0034] Example 3: The rotating mechanism includes a second pressure plate 801, which is disposed inside the second fixed cylinder 8. A second flexible bladder 802 is fixedly connected to the bottom of the second pressure plate 801. A magnetic fluid is disposed inside the second flexible bladder 802. A second electromagnet 804 is fixedly connected to the top of the second pressure plate 801. When the second electromagnet 804 is energized, the second flexible bladder 802 is solidified. A mounting plate 803 is fixedly connected inside the second fixed cylinder 8. A drive motor 805 is fixedly connected to the top of the mounting plate 803. The output shaft of the drive motor 805 passes through the mounting plate 803 and is fixedly connected to the second pressure plate 801.

[0035] The switching mechanism includes a guide frame 601, which is fixedly connected to the bottom of the fixed frame 6 and is located outside the first fixed cylinder 7 and the second fixed cylinder 8. Two guide grooves 602 are provided on both sides of the guide frame 601, and the two guide grooves 602 are symmetrically arranged.

[0036] The switching mechanism also includes two fixed frames 604, both of which are located inside the fixed frame 6. Two hydraulic push rods 603 are fixedly connected inside the fixed frame 6. The telescopic ends of the two hydraulic push rods 603 pass through the fixed frame 6 and are fixedly connected to the first fixed cylinder 7 and the second fixed cylinder 8, respectively. A fixed rod 605 is fixedly connected inside the fixed frame 604. A slider 606 is fixedly connected to the top of the first fixed cylinder 7 and the second fixed cylinder 8. The fixed rod 605 passes through the slider 606 and is slidably connected to the slider 606. A guide shaft 607 is fixedly connected to the outside of the first fixed cylinder 7 and the second fixed cylinder 8. The guide shaft 607 extends into the guide groove 602 and is slidably connected to the guide frame 601.

[0037] In practice, firstly, the emergency stop knob on the control panel is identified and located by the recognition camera 600. Then, the corresponding hydraulic push rod 603 in the switching mechanism is activated. This hydraulic push rod drives the fixed frame 604 to descend, and the fixed frame 604 drives the second fixed cylinder 8 to descend synchronously via the fixed rod 605. During the descent, the guide shaft 607 on the outer side of the second fixed cylinder 8 slides along the guide groove 602 on the outer side of the guide frame 601, thereby ensuring that the second fixed cylinder 8 extends vertically downwards from the guide frame 601. Once the second fixed cylinder 8 extends into position, the combined module 502 lowers the second fixed cylinder 8 as a whole, causing the emergency stop knob to insert into the second flexible bladder 802. The second flexible bladder 802 is in an uncured state, capable of adaptively wrapping the entire outer contour of the knob. At this time, the second electromagnet 804 at the top of the second pressure plate 801 is energized, generating a magnetic field that instantly solidifies the magnetic fluid inside the second flexible bladder 802, forming a rigid clamping sleeve that tightly fits the shape of the knob, reliably fixing the knob in place. Next, the combined module 502 continues to descend the predetermined pressing stroke, simulating the pressing action during actual use. The electrical signal triggered by the knob pressing is checked via terminal 10 to ensure it is normal. After the pressing test is completed, the drive motor 805 is started. The output shaft of the drive motor 805 drives the second pressure plate 801 and the solidified second flexible bladder 802 to rotate together, thereby rotating the knob. During rotation, the output signal of the knob encoder or potentiometer is monitored via terminal 10 to determine if its rotation function is normal. Integrating pressing and rotation tests into the same station eliminates the need to change actuators, improving testing efficiency. Furthermore, the unsolidified second flexible bladder 802 can adaptively wrap around knobs of different diameters and shapes, including those with anti-slip textures or irregularly shaped handles. After solidification, it can transmit sufficient torque without scratching the knob surface.

[0038] Example 4: The clamping mechanism includes two second clamping plates 302 and two first clamping plates 301. The two second clamping plates 302 and the two first clamping plates 301 extend into the fixed plate 201 and are slidably connected to the fixed plate 201. The fixed plate 201 is provided with two lead screws. The two lead screws are respectively connected to the two first clamping plates 301 and the two second clamping plates 302 through ball nut pairs to drive the two first clamping plates 301 to move relative to each other and the two second clamping plates 302 to move relative to each other.

[0039] In practice, two external motors are set up, and the output shafts of the motors drive two lead screws to rotate. The rotation of the two lead screws causes the two second clamping plates 302 and the two first clamping plates 301 to move relative to each other, thereby achieving the fixed clamping of the operation panel.

[0040] In this embodiment, the clamping mechanism further includes multiple striking rods 303, all of which are disposed on one side of the second clamping plate 302. The striking rods 303 penetrate the second clamping plate 302 and are slidably connected to it. A magnet 305 is fixedly connected to one end of the striking rod 303. A spring 304 is fixedly connected between the magnet 305 and the second clamping plate 302, and the spring 304 is sleeved on the outside of the striking rod 303. A guide plate 307 is fixedly connected to one side of the second clamping plate 302. A reciprocating screw 306 is rotatably connected to one side of the second clamping plate 302. A magnetic block 308 is connected to the outside of the reciprocating screw 306 through a ball nut pair. The magnetic block 308 is magnetically attracted to the magnet 305, and the magnetic block 308 is slidably connected to the guide plate 307.

[0041] In specific implementation, multiple second clamping plates 302 are also set on one side of the second clamping plate 302. Before testing, an external motor is used to drive the reciprocating screw 306 through its output shaft. The reciprocating screw 306 drives the magnetic block 308 to move on one side of the second clamping plate 302. The magnetic block 308 and the magnet 305 are magnetically attracted, causing the magnetic block 308 to drive the striking rod 303 to move, which stretches the spring 304. When the magnetic block 308 separates from the magnet 305, the spring 304 pulls the magnet 305 to reset it, causing the striking rod 303 to strike the clamped operation panel. By striking appropriately, it is possible to avoid situations where poor soldering and bad contact are difficult to detect.

[0042] A smart testing method based on CNC machine tool operation panel processing includes the following steps: Step 1: Place the operation panel to be tested on the top of the fixing plate 201 and fix it with the clamping mechanism.
