Technical Field

[0001] The present invention relates to the technical field of luggage processing, and particularly to an intelligent cutting device for processing pull rod luggage. Background Art

[0002] For pull rod luggage, through the structural cooperation of the pull rod and the wheels, users can easily pull the luggage to move, without having to carry the heavy luggage laboriously, which greatly saves physical strength for users. When processing luggage, a cutting device is needed to cut the leather material.

[0003] At present, during the cutting process of luggage fabrics, they may be deformed or stretched due to the pressure and friction of the cutting tool, especially for some fabrics with greater elasticity, resulting in the actual cut shape not matching the designed shape. Especially in the curved surface part, the deformation may be more obvious. When cutting elastic nylon fabrics, stretching is likely to occur at the curved parts of the curved surface, affecting the quality of the final product. Therefore, an intelligent cutting device for processing pull rod luggage needs to be proposed. Summary of the Invention

A pulsed laser cutting head is installed at the end of the angle adjustment component, which is used to accurately control the cutting angle of the pulsed laser cutting head during the processing of pull rod luggage according to the cutting requirements of the luggage through its own angle adjustment function. A pneumatic vibration shearing structure is installed at the bottom of the angle adjustment component. Adsorption control components are symmetrically installed on the left and right surfaces of the pneumatic vibration shearing structure, which are used to stabilize the raw material of the pull rod luggage during the cutting process to prevent it from shifting. The adsorption regulation component has an annular microfluidic channel, a built-in micro air pump and a liquid nitrogen microdroplet ring pipe. The liquid nitrogen microdroplet ring pipe is arranged on the bottom wall surface of the annular microfluidic channel. The built-in micro air pump is connected to the annular microfluidic channel and can precisely control the magnitude of the adsorption force by adjusting the air pressure in the annular microfluidic channel. The liquid nitrogen microdroplet ring pipe can precisely release a liquid nitrogen microdroplet spray according to the temperature requirements during the cutting process of the pneumatic vibration shearing structure, so as to adapt to the thermal deformation control requirements of different materials during the cutting process.

[0006] Preferably, the adsorption regulation component further includes a short-distance sliding guide rail. A first gear torque arm is slidably connected to the side end of the short-distance sliding guide rail. By sliding the first gear torque arm on the short-distance sliding guide rail, the working position of the annular microfluidic channel can be flexibly adjusted to better adapt to the shape of the raw material of the rolling suitcase. An actuator is arranged at the side end of the first gear torque arm, and a second gear torque arm is arranged at the side end of the actuator.

[0007] Preferably, a third gear torque arm is arranged at the side end of the second gear torque arm. The actuator is used to control the coordinated movement of the second gear torque arm and the third gear torque arm. The bottom of the third gear torque arm is connected to the top surface of the annular microfluidic channel to achieve precise adjustment of the position or posture of the annular microfluidic channel.

[0008] Preferably, the bottom end of the built-in micro air pump is connected to a distribution metering pipe. The bottom end of the distribution metering pipe is connected to a negative pressure adsorption hole through a solenoid valve pipe. A micro pressure delivery pump is arranged at the side end of the annular microfluidic channel, and a pressure valve is arranged at the bottom end of the micro pressure delivery pump. The pressure valve is arranged on the pipe surface of the liquid nitrogen microdroplet ring pipe.

[0009] Preferably, the angle adjustment component includes a driver body. The output end of the driver body is connected to a transmission gear. A pull rod gear is meshed and connected to the side end of the transmission gear. A connecting rod is arranged at the side end of the pull rod gear, and the side end of the connecting rod is arranged with a pulsed laser cutting head.

[0010] Preferably, an execution shaft joint arm is arranged at the side end of the driver body. A stator-rotor structure is arranged on the outer circumference of the end of the execution shaft joint arm, and adaptive fabric flattening components are symmetrically arranged at the left and right ends of the stator-rotor structure.

[0011] Preferably, the adaptive fabric flattening component includes a first horizontal axial guide rail. A long connecting rod is slidably connected to the inside of the bottom end of the first horizontal axial guide rail, and a second horizontal axial guide rail is connected to the bottom end of the long connecting rod.

[0012] Preferably, a third horizontal axial guide rail is slidably connected inside the side end of the second horizontal axial guide rail, a positioning laser position sliding seat is slidably connected inside the side end of the third horizontal axial guide rail, a pneumatic clamping member is installed at the bottom end of the positioning laser position sliding seat, and a micro tension sensor is installed inside the pneumatic clamping member.

[0013] Preferably, a groove cavity is formed inside the annular microfluidic channel, a magnetorheological fluid is filled inside the groove cavity, and a controller is installed on the side surface of the groove cavity. The controller is used to form a controllable viscous damping layer when the magnetorheological fluid is electrified, so that when it is detected that the fabric has a stretching trend by the pneumatic clamping member, the controller adjusts the magnetic field strength to change the damping coefficient of the magnetorheological fluid, provides a reverse binding force for the fabric, and inhibits elastic deformation.

[0014] Preferably, the actuating shaft joint arm is installed at the top mounting position of the cutting platform, and a distributed piezoelectric film sensor matrix is installed inside the cutting platform. The distributed piezoelectric film sensor matrix is used to capture the stress distribution of the fabric in the X / Y / Z axis directions during the cutting process in real time, and is connected to the built-in micro air pump, micro pressure delivery pump, controller and actuator in sequence through wireless signals.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, with the cooperation of the adsorption regulation component, by using the short-distance sliding guide rail and the multi-stage gear torque arm linkage, the annular microfluidic channel can achieve precise adjustment of the three-dimensional space position and posture, quickly adapt to the complex shapes such as the curved surface and edge of the raw material of the rolling luggage. Compared with the traditional fixed adsorption device, this structure can improve the fitting degree between the adsorption area and the fabric surface, and effectively avoid the cutting position caused by local suspension.

[0016] 2. In the present invention, with the cooperation of the adsorption regulation component, the built-in micro air pump and the distributed piezoelectric film sensor are combined to construct a "stress monitoring - feedback regulation" mechanism, which can capture the stress distribution of the fabric in the X / Y / Z axis directions in real time. When a displacement trend is detected, the adsorption force is automatically increased to avoid cutting deviation. On the contrary, when the adsorption force is too large and may cause fabric deformation, the system dynamically reduces the pressure to ensure the integrity of the material.

[0017] 3. In the present invention, with the cooperation of the adsorption control component, the micro pressure delivery pump and the liquid nitrogen micro-droplet loop tube work together to release the liquid nitrogen spray for cooling in real time according to the cutting temperature, and the spray flow rate is accurately regulated by the pressure valve, so that the temperature of the cutting area can be stably controlled within the material tolerance range. Compared with the traditional air-cooling scheme, the thermal deformation rate is reduced, and high-precision cutting is guaranteed. At the same time, the magnetorheological fluid damping layer and the micro tension sensor are linked. When the stretching trend of the fabric is detected, the controller adjusts the magnetic field strength in milliseconds to change the damping coefficient and provide a reverse binding force, which is especially suitable for easily deformable materials such as elastic nylon, and significantly improves the component splicing accuracy.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] In the field of processing of pull rod suitcases, intelligent cutting devices can achieve automated and precise cutting, etc., greatly improving production efficiency and product quality, and promoting the development of the suitcase manufacturing industry to a certain extent. However, in the actual processing and production of pull rod suitcases, due to many problems existing in the existing intelligent cutting devices, the cutting accuracy and efficiency are seriously affected, restricting the further development of the suitcase industry.

[0022] Specifically, for the existing intelligent cutting devices used in the processing of pull rod suitcases, on the one hand, during the cutting process, the fixing effect of the raw materials of the pull rod suitcases is not good, which easily causes the raw materials to displace, resulting in the sizes of the cut parts not meeting the requirements, affecting the quality and assembly of the products. Moreover, for some elastic fabrics, they will be deformed or stretched due to factors such as tool pressure and friction during cutting, especially when cutting curved surface parts, the deformation is more obvious, and it is difficult to ensure the cutting accuracy. On the other hand, the existing cutting devices lack effective means for controlling thermal deformation. When cutting fabrics of different materials, due to different amounts of heat generated during the cutting process, the fabrics are easily thermally deformed, reducing the cutting accuracy. At the same time, for the raw materials of pull rod suitcases with different shapes, the existing cutting devices are difficult to flexibly adjust the position and posture of the cutting components, resulting in poor cutting applicability.

[0023] In addition, according to the research and analysis of the existing processing technology and market demand of pull rod suitcases, it is found that there is an urgent need for an intelligent cutting device that can solve the above problems to improve the processing quality and production efficiency of pull rod suitcases.

[0024] Specifically: In this embodiment, with reference to Figure 1 and Figure 2 as shown: An intelligent cutting device for processing pull rod suitcases includes an angle adjustment component 400. A pulsed laser cutting head is installed at the end of the angle adjustment component 400, which is used to accurately control the cutting angle of the pulsed laser cutting head through its own angle adjustment function according to the cutting requirements of the suitcase during the processing of the pull rod suitcase. A pneumatic vibration shearing structure 500 is installed at the bottom of the angle adjustment component 400. Adsorption control components 600 are symmetrically installed on the left and right surfaces of the pneumatic vibration shearing structure 500, which are used to stabilize the raw materials of the pull rod suitcase during the cutting process to prevent them from displacing.

[0025] In the above embodiments, the operator places the raw materials of the rolling suitcase on the cutting platform through the material handling structure or the conveying structure. The distributed piezoelectric thin film sensor matrix inside the cutting platform starts to work, and captures the stress distribution of the fabric in the X / Y / Z axis directions during the cutting process in real time. These data are transmitted to the external control structure through wireless signals.

[0026] The external control structure calculates the angle that the pulsed laser cutting head needs to adjust according to the input cutting pattern and the current state of the fabric.

[0027] This causes the angle adjustment component 400 to start working, driving the pulsed laser cutting head to adjust to the precise cutting angle to meet different cutting requirements, such as straight cutting, curve cutting, or bevel cutting, etc.

[0028] When the pneumatic vibration shearing structure 500 starts cutting, the distributed piezoelectric thin film sensor matrix continuously monitors the stress change of the fabric. If it detects a tendency for the fabric to displace, it indicates that the current adsorption force is insufficient.

[0029] The external control structure sends an instruction to the adsorption control component 600 according to the stress change data, and increases the adsorption force by adjusting the air pressure in the annular microfluidic channel 605 to ensure the fabric is stable. For example, when cutting to the edge or thinner part of the fabric, the fabric is more likely to displace, and the adsorption force will increase accordingly. Conversely, if it detects that the adsorption force on the fabric is too large, which may cause local deformation of the fabric, the external control structure will reduce the air pressure of the built-in micro air pump 607 to decrease the adsorption force.

[0030] And during the cutting process, when heat is generated due to the friction between the pneumatic vibration shearing structure 500 and the fabric, at this time the external control structure estimates the temperature change during the cutting process according to factors such as the cutting speed, force, and the material of the fabric.

[0031] When it detects that the temperature in the cutting area approaches or exceeds the set threshold, the liquid nitrogen microdroplet ring tube 610 precisely releases the liquid nitrogen microdroplet spray according to the temperature requirement. For example, for some temperature-sensitive fabrics, which are more likely to undergo thermal deformation during cutting, the liquid nitrogen microdroplet ring tube 610 will release the liquid nitrogen microdroplet spray more frequently to reduce the temperature of the fabric and control thermal deformation.

[0032] Meanwhile, during the cutting process, as the cutting path changes, it is necessary for the adsorption control component 600 to better adapt to the shape of the raw materials of the rolling suitcase, so that it can adjust the position and attitude of the annular microfluidic channel 605 in real time according to the change of the fabric shape and the cutting position.

[0033] For example, when cutting to a curved surface part, the annular microfluidic channel 605 can be made to fit the curved surface to ensure that the adsorption force is evenly distributed on the fabric and prevent the fabric from displacing during cutting.

[0034] Further, in the above embodiment, according to Figure 5 and Figure 6 as shown, the adsorption control component 600 further includes a short-distance sliding guide rail 602. A first gear torque arm 601 is slidably connected to the side end of the short-distance sliding guide rail 602. By sliding the first gear torque arm 601 on the short-distance sliding guide rail 602, the working position of the annular microfluidic channel 605 can be flexibly adjusted to better adapt to the shape of the raw material of the trolley case. An actuator 608 is arranged at the side end of the first gear torque arm 601, and a second gear torque arm 603 is arranged at the side end of the actuator 608.

[0035] A third gear torque arm 604 is arranged at the side end of the second gear torque arm 603. The actuator 608 is used to control the coordinated movement of the second gear torque arm 603 and the third gear torque arm 604. The bottom of the third gear torque arm 604 is connected to the top surface of the annular microfluidic channel 605, realizing precise adjustment of the position or attitude of the annular microfluidic channel 605.

[0036] The bottom end of the built-in micro air pump 607 is communicated with a distribution and metering pipe 612. The bottom end of the distribution and metering pipe 612 is communicated with a negative pressure adsorption hole 609 through a solenoid valve pipe. A micro pressure delivery pump 606 is arranged at the side end of the annular microfluidic channel 605. A pressure valve 613 is arranged at the bottom end of the micro pressure delivery pump 606, and the pressure valve 613 is arranged on the pipe surface of the liquid nitrogen microdroplet ring pipe 610.

[0037] A cavity is formed inside the annular microfluidic channel 605. The cavity is filled with magnetorheological fluid. A controller is arranged on the side surface of the cavity. The controller is used to form a controllable viscous damping layer when the magnetorheological fluid is electrified, so that when it is detected that the fabric has a stretching tendency by the pneumatic clamping member 307, the controller adjusts the magnetic field strength to change the damping coefficient of the magnetorheological fluid, providing a reverse binding force for the fabric and suppressing elastic deformation.

[0038] Specifically, when the cutting operation is started, the external control structure will determine whether the annular microfluidic channel 605 needs to be adjusted in position to adapt to the current cutting area according to the preset shape data of the raw material of the trolley case and the real-time cutting position information.

[0039] If the position needs to be adjusted, the external control structure will drive the first gear torque arm 601 to slide along the short-distance sliding guide rail 602. For example, when cutting to the edge of the raw material or a region with a more complex shape, the first gear torque arm 601 slides to a suitable position, thereby driving the annular microfluidic channel 605 to move to the corresponding cutting area.

[0040] Meanwhile, the actuator 608 controls the coordinated movement of the second gear torque arm 603 and the third gear torque arm 604 according to the instructions of the external control structure. The movement of these two gear torque arms can change the attitude of the annular microfluidic channel 605, enabling it to better conform to the surface shape of the raw material of the trolley case. For example, when cutting the curved surface part, by adjusting the angles of the second and third gear torque arms, the annular microfluidic channel 605 is made to be consistent with the curved surface to ensure uniform adsorption effect.

[0041] Next, the built-in micro air pump 607 starts to work, and conveys gas to the negative pressure adsorption holes 609 through the distribution pipe 612 and the solenoid valve pipe, forming an adsorption force at the negative pressure adsorption holes 609 to firmly adsorb the raw material of the trolley case under the annular microfluidic channel 605.

[0042] Meanwhile, the distributed piezoelectric film sensor matrix in the cutting platform monitors the stress distribution of the fabric in the X / Y / Z axis directions in real time. If it detects a tendency of the fabric to displace, it indicates that the current adsorption force is insufficient. At this time, the external control structure will increase the air pressure of the built-in micro air pump 607, thereby increasing the adsorption force of the negative pressure adsorption holes 609 to prevent the fabric from displacing.

[0043] Conversely, if it detects that the adsorption force on the fabric is too large, which may cause local deformation of the fabric, the external control structure will reduce the air pressure of the built-in micro air pump 607 to decrease the adsorption force.

[0044] Secondly, the micro pressure delivery pump 606 operates according to the preset parameters to provide a stable pressure for the annular microfluidic channel 605. The pressure valve 613 monitors and adjusts the pressure of the liquid nitrogen microdroplet ring pipe 610 in real time to ensure that its pressure is within a safe and appropriate range.

[0045] During the cutting process, since heat is generated due to the friction between the pneumatic vibration shearing structure 500 and the fabric, when the external control structure estimates that the temperature of the cutting area is close to or exceeds the set threshold according to factors such as the cutting speed, force, and fabric material, it will turn on the micro pressure delivery pump 606 and adjust the pressure valve 613 to make the liquid nitrogen microdroplet ring pipe 610 accurately release the liquid nitrogen microdroplet spray to lower the fabric temperature and control thermal deformation.

[0046] At this time, the micro tension sensor 306 monitors the tension change of the fabric in real time. When it detects a tendency of the fabric to be stretched by the pneumatic clamping member 307, it indicates that the fabric may undergo elastic deformation.

[0047] The controller on the side end of the magnetorheological fluid tank cavity will receive instructions from an external control structure, adjust the magnetic field strength, change the damping coefficient of the magnetorheological fluid, and the magnetorheological fluid forms a controllable viscous damping layer to provide a reverse binding force for the fabric and inhibit elastic deformation. For example, when cutting a fabric with a large elasticity, the controller will increase the magnetic field strength, increase the damping coefficient of the magnetorheological fluid, and enhance the inhibitory effect on elastic deformation.

[0048] For example, in some embodiments, according to Figure 3 As shown, the angle adjustment assembly 400 includes a driver body 401. The output end of the driver body 401 is connected with a transmission gear 402. The side end of the transmission gear 402 is meshed and connected with a pull rod gear 403. A connecting rod 404 is arranged at the side end of the pull rod gear 403. The side end of the connecting rod 404 is arranged with a pulsed laser cutting head. The external control structure analyzes the cutting path data and identifies the nodes (such as the starting point of the curve, the turning point of the hypotenuse) that need to adjust the cutting angle.

[0049] According to the cutting pattern and the current position, calculate the target angle (such as θ = 30°) that the pulsed laser cutting head needs to adjust, and convert it into a control signal for the driver body 401.

[0050] Make the driver body 401 (such as a servo motor) start according to the control signal, and the output shaft drives the transmission gear 402 to rotate.

[0051] The transmission gear 402 meshes with the pull rod gear 403, and converts the rotational motion into the eccentric rotation of the pull rod gear 403.

[0052] After that, the eccentric rotation of the pull rod gear 403 is transmitted to the pulsed laser cutting head through the connecting rod 404.

[0053] The length and hinge point design of the connecting rod 404 ensure that the cutting head swings at a preset angle (such as the principle of a sine mechanism).

[0054] The pulsed laser cutting head is built-in (such as an encoder) to real-time feedback the current angle and compare it with the target angle.

[0055] The external control structure dynamically adjusts the rotation speed or direction of the driver body 401 according to the deviation to achieve closed-loop control (such as ±0.1° precision adjustment).

[0056] When cutting a curve or a special-shaped contour (such as the arc corner of a luggage), the external control structure calculates a new angle in real time at the path inflection point and drives the angle adjustment assembly 400 to respond dynamically. For example, when changing from a straight-line cutting to a 45° oblique cutting, the driver body 401 quickly adjusts and drives the cutting head to complete the angle switching within 0.5 seconds.

[0057] If the distributed piezoelectric film sensor detects local deformation of the fabric (such as surface tilt caused by wrinkles), the angle adjustment component 400 cooperates with the adaptive fabric flattening component 300 to dynamically correct the angle of the cutting head to fit the deformed surface and avoid cutting deviation.

[0058] When cutting fabrics of different hardness or thickness (such as alternating cutting of leather and nylon), to optimize the cutting effect, the external control structure automatically adjusts the angle of the cutting head and the laser power to work together. For example, when cutting leather, the incident angle is increased to reduce the heat affected zone, so that during shearing, the pulsed laser cutting head pre-melts the surface layer of the fabric (such as a depth of 0.1 mm) to form a weakening line, and then the pneumatic vibration shearing structure 500 performs secondary cutting along the laser path.

[0059] After the pulsed laser cutting head reaches the target angle, the driver body 401 maintains torque lock to prevent angle deviation caused by cutting vibration.

[0060] The encoder transmits the final angle data back to the external control structure. After confirming the successful adjustment, the pulsed laser cutting head performs the cutting task at the new angle.

[0061] If the meshing of the transmission gear 402 and the pull rod gear 403 is blocked (such as jammed by foreign objects), the driver body 401 triggers an overcurrent detection, automatically stops and alarms.

[0062] When the angle deviation exceeds the threshold (such as ±0.5°), the external control structure enables a redundant adjustment algorithm to restore the accuracy through multiple small-scale corrections.

[0063] Specifically: In this embodiment, refer to Figure 4 As shown: An execution shaft joint arm 100 is installed at the side end of the driver body 401, a stator-rotor structure 200 is installed on the outer circumference of the end of the execution shaft joint arm 100, and adaptive fabric flattening components 300 are symmetrically installed at the left and right ends of the stator-rotor structure 200.

[0064] The adaptive fabric flattening component 300 includes a first horizontal axial guide rail 301, a long connecting rod 302 is slidably connected inside the bottom end of the first horizontal axial guide rail 301, and the bottom end of the long connecting rod 302 is connected to a second horizontal axial guide rail 303.

[0065] A third horizontal axial guide rail 304 is slidably connected inside the side end of the second horizontal axial guide rail 303, a positioning laser position sliding seat 305 is slidably connected inside the side end of the third horizontal axial guide rail 304, a pneumatic clamping member 307 is installed at the bottom end of the positioning laser position sliding seat 305, and a micro tension sensor 306 is installed inside the pneumatic clamping member 307.

[0066] The execution link arm 100 is installed at the top mounting position of the cutting platform. Inside the cutting platform, a distributed piezoelectric film sensor matrix is installed. The distributed piezoelectric film sensor matrix is used to capture the stress distribution of the fabric in the X / Y / Z axis directions in real time during the cutting process, and is connected to the built-in micro air pump 607, micro pressure delivery pump 606, controller, and actuator 608 in sequence through wireless signals.

[0067] The distributed piezoelectric film sensor matrix collects the stress data of the fabric in the X / Y / Z axes at a frequency of 100 Hz to locate uneven areas such as wrinkles and protrusions.

[0068] The external control structure determines whether the flatness of the fabric meets the standard based on the stress data (e.g., local stress difference > threshold 0.5 kPa). If it does not meet the standard, the adaptive flattening process is started.

[0069] The execution link arm 100 is displaced above the target area. At this time, the stator-rotor structure 200 rotates outside the end of the execution link arm 100 to keep the symmetric adaptive fabric flattening assembly 300 stable, and the first horizontal axial guide rail 301 and the second horizontal axial guide rail 303 cooperate to expand and contract, driving the third horizontal axial guide rail 304 to be positioned at the edge of the uneven area.

[0070] Then the positioning laser position slider 305 emits a positioning laser to mark the grasping points of the pneumatic clamping members 307, ensuring that the clamping points avoid the cutting path.

[0071] After that, the pneumatic clamping members 307 close, and the micro tension sensor 306 monitors the clamping force in real time (initially set to 1 - 3 N) to prevent fabric damage.

[0072] The distributed piezoelectric film sensor matrix continuously monitors the stress change of the fabric, and the external control structure dynamically adjusts the flattening strategy according to the stress distribution: If a concave area is detected, the corresponding pneumatic clamping member 307 fine-tunes the height through the long connecting rod 302 to stretch the fabric to flatness with an accuracy of 0.1 mm.

[0073] Two groups of pneumatic clamping members 307 cooperate to form a "tension gradient" through the expansion and contraction of the guide rails to gradually unfold the wrinkles.

[0074] And it forms a linkage with the adsorption control component 600: When the fabric is flattened, the stress data is synchronously transmitted to the adsorption control component 600: The built-in micro air pump 607 adjusts the adsorption force according to the shape of the flattened fabric (e.g., the adsorption force in the flattened area is increased by 20%); The magnetorheological fluid controller pre-adjusts the damping coefficient according to the data of the tension sensor 306 to match the subsequent cutting force.

[0075] And during cutting, if the distributed piezoelectric film sensor detects local deformation of the fabric due to the pressure of the cutting tool (such as compression of elastic fabric): The pneumatic clamping member 307 synchronously and finely adjusts its height to compensate for the fabric deformation (response time < 50 ms); The angle adjustment assembly 400 corrects the angle of the laser cutting head according to the actual fabric surface after leveling.

[0076] So that the pressure data of the micro tension sensor 306, the distributed piezoelectric film sensor matrix, and the adsorption control assembly 600 form a triangular check: If the tension sensor 306 detects an abnormal tensile force (> 5 N), the external control structure immediately pauses the cutting to check for fabric jamming or adsorption failure.

[0077] The wiring diagrams of the distributed piezoelectric film sensor matrix and the micro tension sensor 306 in the present invention belong to the common knowledge in the art. Their working principles are already well-known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the distributed piezoelectric film sensor matrix and the micro tension sensor 306 will not be explained in detail.

[0078] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
