[0002] Clothing is a general term for clothes, shoes, bags and accessories, mostly referring to clothes. Clothes are products that protect and decorate the human body. In the process of producing clothes, the fabric is usually cut by a fabric cutting device and then sewn.

[0003] However, in the prior art, due to the softness and texture differences of fabrics, the fabrics are easily deformed by the impact energy of the laser during laser cutting, which makes the cutting edges rough, wrinkled or burnt. At the same time, it is difficult to accurately control the focal position of the laser beam and keep it constant throughout the cutting path, resulting in uneven cutting depth, making the cutting edges wavy or stepped, affecting the refinement of the clothing and subsequent processing steps, and reducing the product qualification rate.

[0020] Cutting method of a laser cutting device for a clothing fabric, comprising the following steps:

[0021] S1. First, a conveying operation of the fabric is formed by a feeding roller and a winding roller. Then, the displacement axis is used to adjust the fixed-point component to drive the azimuth cutting adjustment component and the cutting dynamic leveling component to adjust the displacement of the laser cutting generator;

[0022] S2. After that, the fabric adsorption plate is displaced and adjusted under the cooperation of the sliding edge, the rack, and the positive and negative control drive gears, and then the fabric is cut;

[0023] S3. Secondly, during the cutting process, by adjusting the azimuth cutting adjustment component and the cutting dynamic leveling component, during the cutting process, according to the deformation amount of the fabric, a real-time dynamic leveling operation can be actively formed when the fabric is cut, ensuring that the fabric is always flat and located on the cutting line during the cutting operation;

[0024] S4. At the same time, under the cooperation of the cutting dynamic leveling component, during the cutting process, by optimizing the gas injection angle, flow rate, and speed parameters of the gas injector, the generated argon gas curtain can accurately cover the cutting edge, minimizing the range and influence degree of the heat affected zone to the greatest extent.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. In the present invention, under the cooperation of the cutting dynamic leveling component, after the overall device receives the start cutting instruction, the laser displacement sensor and the vision sensor installed on the cutting dynamic leveling component are used to monitor the flatness and deformation amount of the fabric in real time. When the fabric is uneven locally, the logic controller controls the electric telescopic rod to extend or contract, driving the installation frame, the short-distance screw rod adjustment rail, the sliding distance connecting frame, and the chassis sliding frame to rise or fall as a whole, so that the pressing plate and the pressing arc plate contact the fabric and apply appropriate pressure to adjust the fabric to a flat state. When the fabric has a local depression, the electric telescopic rod extends, pressing the pressing plate down on the depressed part to make it return to the same height as the surrounding fabric. And during the entire cutting process, the laser displacement sensor and the vision sensor continuously monitor the state of the fabric, the logic controller continuously receives the sensor data and optimizes the adjustment parameters in real time according to the new data. When it is found that the previous adjustment effect is not ideal or the fabric has a new deformation, the logic controller immediately recalculates the adjustment amount and sends a control instruction to make the cutting dynamic leveling component make corresponding readjustment, ensuring that the fabric always remains flat and located on the cutting line, guaranteeing the stability and consistency of the cutting quality.

[0027] 2. In the present invention, with the cooperation of the cutting dynamic leveling component, when the fabric is displaced in the horizontal direction, the driving motor is started to drive the short adjusting rod to rotate, thereby making the chassis sliding frame slide left and right on the edge of the short adjusting slide rail. At the same time, the bottom adjusting motor can drive the first rotating disk to rotate as needed to change the angle of the chassis sliding frame to achieve precise adjustment in the horizontal direction. When the fabric is twisted clockwise, the bottom adjusting motor drives the first rotating disk to rotate counterclockwise, and at the same time, the driving motor controls the chassis sliding frame to move left to correct the distortion of the fabric. When it is necessary to adjust the contact angle between the pressing plate and the arc pressing plate and the fabric, the angle control motor is started to drive the second rotating disk to rotate relative to the first rotating disk, thereby changing the inclination angle of the pressing plate and the arc pressing plate, so that the surface of the fabric has a certain curvature or the fabric is partially warped due to stress changes during the cutting process. When the edge of the fabric tends to warp upward due to laser cutting, the angle control motor drives the second rotating disk to rotate, so that the arc pressing plate presses down the warped part at a suitable angle to flatten it.

[0028] 3. In the present invention, by cooperating with the azimuth cutting adjustment component and the displacement axis adjustment fixed point component, during the cutting operation, as the cutting path changes and various factors that may arise (such as local characteristic differences of the fabric, slight vibration of the equipment, etc.) during the laser cutting process, the logic controller sends corresponding control signals to the first control energy-saving motor and the second control energy-saving motor based on the real-time monitoring data, so that they work together to make real-time fine adjustments to the azimuth angle of the laser cutting generator to ensure that the laser beam can always be aligned with the cutting line at the correct angle and azimuth, thereby ensuring the cutting quality and accuracy.

Detailed implementation mode

[0040] 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 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.

[0041] In the field of laser cutting of clothing fabrics, there are many inconveniences in the existing technologies.

[0042] 1. In the aspect of cutting clothing fabrics, it is difficult for existing devices to accurately control the fixing and cutting processes of fabrics. For example, when fixing fabrics, it is impossible to automatically and accurately adjust the adsorption area according to the size and thickness of the fabrics, resulting in displacement, wrinkles, etc. of the fabrics during the cutting process, affecting the cutting accuracy and quality.

[0043] 2. During the cutting operation process, the adjustment of the orientation and angle of the cutting head is not flexible and accurate enough to meet the requirements of complex patterns and diverse cutting needs. Moreover, during the cutting process, there is a lack of effective dynamic leveling means. When the fabric has a deformation, it cannot be adjusted in a timely and proactive manner, resulting in the cutting line shifting and the cutting effect being poor.

[0044] 3. At the same time, the heat generated during the cutting process will cause problems such as thermal deformation of the fabric. Existing devices do not have effective isolation and protection measures, and the heat affected zone is relatively large, seriously affecting the subsequent use performance of the fabric.

[0045] The present invention aims to solve these problems in the existing technologies and achieve high-precision and high-quality laser cutting of clothing fabrics through innovative structural designs and control methods.

[0046] The purpose of the present invention is to provide a laser cutting device for clothing fabrics and its cutting method to solve the problems in the existing technologies such as inaccurate fabric fixing, inflexible cutting head adjustment, lack of dynamic leveling, and insufficient thermal protection.

[0047] To achieve the above purpose, the present invention provides the following technical solutions. Referring to Figure 1 、 Figure 2 and Figure 5 shown: A laser cutting device for clothing fabrics includes:

[0048] A support frame body 1 and a fabric adsorption plate 3. The top of the support frame body 1 is respectively provided with a sliding edge 20 and a rack 21 for installing the fabric adsorption plate 3.

[0049] The fabric adsorption plate 3 is slidably connected to the top of the support frame body 1, and an array of negative pressure adsorption holes 4 are opened on its surface for automatically adjusting the adsorption area according to the size and thickness of the fabric.

[0050] The laser cutting generator 18 is provided with an azimuth cutting adjustment component 10 on its side end, and cutting dynamic leveling components 11 are symmetrically arranged at the left and right ends of the laser cutting generator 18.

[0051] The displacement axis adjustment fixed-point component 9, which includes a horizontal hinge guide rail 902, a vertical hinge guide rail 903, and a connecting sliding frame 904, is installed on the top of the support frame body 1 through a connecting structure 901, driving the azimuth cutting adjustment component 10 and the laser cutting generator 18 to achieve X-Y axis linkage.

[0052] The displacement axis adjustment fixed-point component 9 further includes a connecting structure 901, which is installed on the top of the support frame body 1. The vertical hinge guide rail 903 is slidably connected to the side of the horizontal hinge guide rail 902, and the connecting sliding frame 904 is slidably connected to the side of the vertical hinge guide rail 903. The horizontal hinge guide rail 902 is installed on the top of the connecting structure 901 and is used to drive the vertical hinge guide rail 903, the connecting sliding frame 904 connected thereto, and the azimuth cutting adjustment component 10 for displacement adjustment, and the vertical hinge guide rail 903 drives the connecting sliding frame 904 for adjustment.

[0053] According to an embodiment of the present invention, first, the logic controller sends a control signal to the horizontal hinge guide rail 902 according to the abscissa information of the starting position, so that the vertical hinge guide rail 903 and the connecting sliding frame 904 thereon start to move in the horizontal direction. During the movement, the position sensor installed on the connecting sliding frame 904 monitors the horizontal displacement in real time and feeds the data back to the logic controller. After the horizontal positioning is completed, the logic controller sends a control signal to the vertical hinge guide rail 903, causing the vertical hinge guide rail 903 to start and drive the connecting sliding frame 904 to move in the vertical direction. Similarly, the position sensor monitors the vertical displacement in real time and feeds it back to the logic controller, so that the laser cutting generator 18 is positioned at the accurate position of the cutting starting point. When performing cutting operations with different depths (such as cutting multiple layers of clothing fabrics or engraving patterns with different depths on the fabric), the vertical hinge guide rail 903 can perform precise depth adjustment according to the instructions of the logic controller. By controlling the vertical hinge guide rail 903, a small displacement of the connecting sliding frame 904 in the vertical direction is achieved, thereby adjusting the distance between the laser cutting generator 18 and the fabric, changing the focusing position and energy density of the laser beam, meeting the requirements of cutting with different depths. During the laser cutting process, the logic controller continuously sends control signals to the horizontal hinge guide rail 902 and the vertical hinge guide rail 903 according to the preset cutting trajectory coordinates, so that the connecting sliding frame 904 drives the laser cutting generator 18 to move along the predetermined cutting path, ensuring that the laser cutting generator 18 always moves accurately along the cutting trajectory, guaranteeing the cutting accuracy and quality, and enabling the generated dynamic adjustment process to be carried out in real time throughout the cutting process to adapt to various possible changing situations.

[0054] In some embodiments, such as Figure 1 and Figures 6 - 9 shown, the cutting dynamic leveling assembly 11 includes an electric telescopic rod 114, a short-distance screw rod adjustment rail 116, a pressing plate 1192, an inert gas curtain generator 111, a pneumatic adjustment joint 112, and a gas injector 113. The pressing plate 1192 is driven by the short-distance screw rod adjustment rail 116 to compensate for the fabric deformation in real time. At the same time, the inert gas curtain generator 111 drives the gas injector 113 through the pneumatic adjustment joint 112 to form an argon gas curtain.

[0055] The cutting dynamic leveling component 11 further includes a side groove frame 110, which is fixedly installed on the surface of the side edge frame of the laser cutting generator 18. The inert gas curtain generator 111 is installed inside the side groove frame 110. The gas injector 113 is installed at the bottom of the pneumatic adjustment joint 112. The pneumatic adjustment joint 112 is installed at the bottom end of the inert gas curtain generator 111. The electric telescopic rod 114 is installed on the side of the side groove frame 110. The gas injector 113 is driven by the pneumatic adjustment joint 112 installed at the bottom to form an argon gas curtain, so that the formed gas curtain isolates the cutting area from the outside air during the laser cutting operation.

[0056] An installation frame 115 is fixedly connected to the side end of the electric telescopic rod 114. A short-distance screw rod adjustment rail 116 is installed inside the installation frame 115. A sliding distance connection frame 117 is slidably connected to the outside of the short-distance screw rod adjustment rail 116. A chassis sliding frame 118 is fixedly connected to the bottom of the sliding distance connection frame 117. A short adjustment slide rail edge 119 is slidably connected to the bottom of the chassis sliding frame 118. A short adjustment rod 1196 is installed on the top of the chassis sliding frame 118. A drive motor 1197 is installed at the side end of the short adjustment rod 1196. A first rotating disk 1190 is rotationally connected to the side end surface of the short adjustment slide rail edge 119 through a bottom adjustment motor. An angle control motor 1194 is installed on the side end surface of the first rotating disk 1190. A rotation angle sensor 1195 is installed on the side of the first rotating disk 1190. A second rotating disk 1191 is rotationally connected to the side end of the first rotating disk 1190. A pressing plate 1192 is fixedly connected to the bottom of the side end of the second rotating disk 1191. Pressing arc plates 1193 are integrally formed on the left and right side ends of the pressing plate 1192.

[0057] According to the embodiment of the present invention, specifically: after the overall device receives the start cutting instruction, the logic controller calculates the initial working parameters of the cutting dynamic leveling component 11 according to the preset cutting parameters and fabric information, including the flow rate, pressure of the inert gas curtain and the initial position of each adjustment component, the inert gas curtain generator 111 is started, and the angle and position of the gas injector 113 are adjusted by the pneumatic adjustment shaft 112, and argon gas is sprayed into the cutting area to form a stable argon gas curtain. The gas curtain effectively isolates the cutting area from the outside air, reduces the oxygen entering the cutting area, and prevents the fabric from discoloring, burning and other undesirable phenomena due to oxidation during the laser cutting process. At the same time, the argon gas can quickly take away the heat during the cutting process and reduce the temperature of the heat-affected zone. Protect the physical and chemical properties of the fabric. With the start of laser cutting, secondly, use the laser displacement sensor and visual sensor installed on the cutting dynamic leveling component 11 to monitor the flatness and deformation of the fabric in real time, so that the laser displacement sensor and the visual sensor transmit the collected data to the logic controller, and the logic controller analyzes and processes the data to determine whether the fabric is deformed and the degree, location and type of deformation (such as local depression, protrusion, distortion, etc.). According to the analysis results, when the fabric is locally uneven, the logic controller controls the electric telescopic rod 114 to extend or contract, driving the installation frame 115, the short-distance screw adjustment rail 116, the sliding distance connecting frame 117 and the chassis sliding frame 118 to rise or fall as a whole, so as to The pressing plate 1192 and the arc pressing plate 1193 are made to contact the fabric and apply appropriate pressure to adjust the fabric to a flat state. When the fabric is partially concave, the electric telescopic rod 114 is extended to make the pressing plate 1192 press down the concave part to restore it to the same height as the surrounding fabric. When the fabric is displaced in the horizontal direction, the driving motor 1197 is started to drive the short adjustment rod 1196 to rotate, thereby making the chassis sliding frame 118 slide left and right on the short adjustment slide rail edge 119. At the same time, the bottom adjustment motor can drive the first rotating disk 1190 to rotate as needed to change the angle of the chassis sliding frame 118 to achieve precise adjustment in the horizontal direction. When the fabric is twisted clockwise, the bottom adjustment motor drives the first rotating disk 1190 to rotate counterclockwise, and at the same time drives the motor 1 197 controls the chassis sliding frame 118 to move leftward to correct the distortion of the fabric. When it is necessary to adjust the contact angle between the pressing plate 1192 and the arc pressing plate 1193 and the fabric, the angle control motor 1194 is started, and under the detection feedback of the rotation angle sensor 1195, the second rotating disk 1191 is driven to rotate relative to the first rotating disk 1190, thereby changing the inclination angle of the pressing plate 1192 and the arc pressing plate 1193, so that the surface of the processed fabric has a certain curvature or the fabric is partially warped due to stress changes during the cutting process. When the edge of the fabric tends to warp upward due to laser cutting, the angle control motor 1194 drives the second rotating disk 1191 to rotate, so that the arc pressing plate 1193 presses down the warped part at a suitable angle to flatten it.And during the entire cutting process, the laser displacement sensor and the vision sensor continuously monitor the state of the fabric. The logic controller constantly receives the sensor data and optimizes the adjustment parameters in real time according to the new data. If it is found that the previous adjustment effect is not ideal or new deformations occur in the fabric, the logic controller immediately recalculates the adjustment amount and sends a control instruction to make the cutting dynamic leveling component 11 make corresponding readjustments to ensure that the fabric always remains flat on the cutting line, guaranteeing the stability and consistency of the cutting quality.

[0058] In some embodiments, such as Figure 1 and Figure 6 shown, the azimuth cutting adjustment component 10 includes a connecting rotating frame 101, a first control energy-saving motor 102, a first rotating connecting frame 103, a second control energy-saving motor 104, and a second rotating connecting frame 105. The azimuth cutting adjustment component 10 is installed on the connecting sliding frame 904 through the connecting rotating frame 101. The first control energy-saving motor 102 is used to drive the first rotating connecting frame 103 to achieve azimuth adjustment, and the second control energy-saving motor 104 is used to drive the second rotating connecting frame 105 to achieve fine angle adjustment.

[0059] The first rotating connecting frame 103 is rotatably connected to the bottom of the connecting rotating frame 101. The connecting rotating frame 101 is installed on the surface of the connecting sliding frame 904. The first control energy-saving motor 102 is installed on the top surface of the connecting rotating frame 101 and is used to drive the first rotating connecting frame 103, the second control energy-saving motor 104, the cutting dynamic leveling component 11, and the laser cutting generator 18 to perform azimuth angle adjustment.

[0060] The laser cutting generator 18 is installed on the side of the second rotating connecting frame 105. The second control energy-saving motor 104 is installed on the inner surface of the side end of the first rotating connecting frame 103 and is used to drive the second rotating connecting frame 105 and the connected laser cutting generator 18 to perform azimuth angle adjustment.

[0061] According to an embodiment of the present invention, more specifically: when a start cutting instruction is received, the logic controller calculates the initial azimuth angle required by the laser cutting generator 18 according to the preset cutting path planning and initial cutting position information. If there is a deviation between the initial azimuth angle and the current azimuth angle, the logic controller first sends a control signal to the first control energy-saving motor 102. The first control energy-saving motor 102 starts and drives the first rotating connecting frame 103 to rotate around the top shaft of the connecting rotating frame 101 according to the received signal, thereby realizing a preliminary adjustment of the azimuth angle in a large range. During this process, the rotation angle of the first rotating connecting frame 103 is monitored in real time by the angle sensor, and the data is fed back to the logic controller. When the rotation angle reaches the preset initial azimuth angle range, the first control energy-saving motor 102 stops rotating. After the first control energy-saving motor 102 completes the preliminary azimuth adjustment, the logic controller analyzes the rotation angle and direction required by the second control energy-saving motor 104 according to the information fed back by the angle sensor and the preset precise cutting azimuth requirement, so that the second control energy-saving motor 104 starts after receiving the control signal, driving the second rotating connecting frame 105 and the laser cutting generator 18 connected thereto to perform a more refined azimuth angle adjustment around the shaft inside the side end of the first rotating connecting frame 103. The high-precision angle sensor monitors the rotation angle of the second rotating connecting frame 105 in real time and feeds the data back to the logic controller. When the rotation angle of the second rotating connecting frame 105 reaches the precise preset azimuth angle, the second control energy-saving motor 104 stops rotating. At this time, the laser cutting generator 18 is in the accurate initial cutting azimuth and is ready to perform the cutting operation, so that during the laser cutting process, with the change of the cutting path and the influence of various possible factors (such as local characteristic differences of the fabric, slight vibrations of the equipment, etc.), the logic controller sends corresponding control signals to the first control energy-saving motor 102 and the second control energy-saving motor 104 respectively according to the real-time monitored data, making them work together to perform real-time fine adjustment of the azimuth angle of the laser cutting generator 18 to ensure that the laser beam can always be aligned with the cutting line at the correct angle and azimuth, guaranteeing the cutting quality and precision.

[0062] In some embodiments, such as Figures 1 - 4 and Figure 10 shown, a first guide rail frame 13 is installed inside the support frame body 1. The top of the first guide rail frame 13 is connected with a second guide rail frame 14 through a sliding saddle block. The first guide rail frame 13 and the second guide rail frame 14 form an X and Y axis regulation. A positioning sliding seat 15 is slidably connected to the top of the second guide rail frame 14. A micro electric guide rod 16 is installed on the top of the positioning sliding seat 15. A negative pressure regulation adsorption end 17 is installed on the top of the micro electric guide rod 16.

[0063] At the left and right ends of the top of the support frame body 1, sliding edges 20 are symmetrically installed. At the side end of the top of the support frame body 1, a rack 21 is installed. The rack 21 and the sliding edges 20 are located at the bottom of the fabric adsorption plate 3 and form a sliding connection therewith. A positive and negative control drive gear 19 is meshed with the side end of the rack 21.

[0064] An optoelectronic detection sensor 12 is installed at the side end of the fabric adsorption plate 3. A feeding roller 2 is installed at the side end of the top of the support frame body 1. A winding roller 8 is installed at the other side end of the top of the support frame body 1.

[0065] Laser protection plates 5 are symmetrically installed on the left and right sides of the support frame body 1. A laser smoke purifier 6 is installed at the top of the laser protection plate 5.

[0066] According to an embodiment of the present invention, more specifically: Start the laser cutting device, install the clothing fabric roll to be cut on the feeding roller 2, and pull one end of the fabric to a suitable position above the fabric adsorption plate 3. Start the positive and negative control drive gear 19, drive the fabric adsorption plate 3 to move along the sliding edges 20 towards the feeding roller 2 through the rack 21, so that the edge of the fabric adsorption plate 3 close to the feeding roller 2 contacts the fabric. At this time, the micro electric guide rod 16 starts to extend, jack up the negative pressure regulation adsorption end 17, make it contact with the fabric and start to generate a negative pressure adsorption force. As the adsorption force gradually increases, the fabric is firmly adsorbed on the fabric adsorption plate 3. The optoelectronic detection sensor 12 continuously monitors the adsorption situation of the fabric to ensure that the fabric is flat and there are no abnormal situations such as wrinkles and displacements. Then the first guide rail frame 13 and the second guide rail frame 14 are started according to the instructions of the logic controller. Through the coordinated movement of the sliding saddle block and the positioning sliding seat 15, the negative pressure regulation adsorption end 17 continuously maintains the adsorption force to ensure that the fabric will not be displaced or deformed due to the action of the laser during the cutting process. When the laser is cutting, the laser smoke purifier 6 continuously works to inhale and purify the smoke and dust generated by the laser cutting. The laser protection plate 5 effectively blocks the scattering of the laser beam and prevents the laser from leaking and causing harm to the operator. During the cutting process, the optoelectronic detection sensor 12 continues to monitor the cutting situation of the fabric. The positive and negative control drive gear 19 reverses, drives the fabric adsorption plate 3 to move towards the winding roller 8. At the same time, the micro electric guide rod 16 contracts, reducing the height of the negative pressure regulation adsorption end 17, separating the cut clothing fabric from the fabric adsorption plate 3, and gradually winding it onto the winding roller 8 during the movement.
