In today's pursuit of personalization and differentiation, the patterns and patterns on clothing are diversified. In the field of garment processing, automatic cutting equipment is usually used to cut or cut fabrics such as cotton and denim. Most of the existing cloth cutting equipment is laser cutting and mechanical cutting. The quality of laser cutting is not ideal for thick or multi-layer cloth cutting. Laser cutting will cause carbonization of the edge of the cloth cutting, which affects the cutting quality.

有益效果beneficial effect
本发明与现有技术相比具有的有益效果是。Compared with the prior art, the present invention has the following beneficial effects.
1、通过旋转机构和直线移动机构取代传统的XY轴运动机构，更有利于进行弧线切割，具体的，控制器发送信号给蜗轮蜗杆驱动组件，蜗轮蜗杆驱动组件收到信号后驱动第一转轴围绕其自身轴线做旋转运动。第一转轴带动直线移动机构一同旋转，在稳定组件的作用下使直线移动机构的旋转更加稳定，避免旋转过程中直线移动机构两端发生倾斜，从而使直线移动机构活动端上的激光刀头、视觉拍摄机构和防碳化机构的工作效果更加稳定。所述第三旋转驱动器为伺服电机。旋转机构对称安装于悬梁两端的部分对直线移动机构的旋转起到引导作用。通过悬梁与旋转机构底端的固定连接使直线移动机构可以随旋转机构一同旋转。控制器发送信号给第三旋转驱动器，第三旋转驱动器收到信号后驱动丝杠在第二轴承座上旋转。在燕尾滑槽的限位和导向作用以及丝杠的驱动作用下，滑块沿着丝杠的轴线做直线运动。燕尾滑槽还能进一步起到防止滑块运动过程中与悬梁分离的作用，使结构更加稳定。1. The traditional XY-axis motion mechanism is replaced by a rotary mechanism and a linear moving mechanism, which is more conducive to arc cutting. Specifically, the controller sends a signal to the worm gear drive assembly, and the worm gear drive assembly drives the first shaft after receiving the signal. Rotate around its own axis. The first rotating shaft drives the linear moving mechanism to rotate together, and under the action of the stabilization component, the rotation of the linear moving mechanism is more stable, and the two ends of the linear moving mechanism are prevented from tilting during the rotation process, so that the laser cutter head on the movable end of the linear moving mechanism, vision The working effect of the shooting mechanism and the anti-carbonization mechanism is more stable. The third rotary driver is a servo motor. The parts of the rotating mechanism symmetrically installed at both ends of the cantilever beam play a guiding role in the rotation of the linear moving mechanism. Through the fixed connection between the cantilever beam and the bottom end of the rotating mechanism, the linear moving mechanism can rotate together with the rotating mechanism. The controller sends a signal to the third rotary driver, and the third rotary driver drives the lead screw to rotate on the second bearing seat after receiving the signal. Under the limiting and guiding action of the dovetail chute and the driving action of the lead screw, the slider moves linearly along the axis of the lead screw. The dovetail chute can further prevent the slider from separating from the cantilever beam during the movement of the slider, making the structure more stable.
2、借助弹力和重力对布料两侧进行固定，节省了能源，且结构简单，具体的，在弹性下压组件的弹力作用下，弹性下压组件的工作端与操作台上端相互抵接，工作人员通过间距调节组件调节压料板在弹性下压组件顶端的水平位置，从而改变一对压料板之间的间距，最终使压料板底端可以压在布料两侧。控制器通过控制抬升组件输出端竖直向上运动从而抬升弹性下压组件、间距调节组件和压料板，使工作人员可以方便地进行上料和下料。当抬升组件解除抬升作用后，在重力和弹力作用下，压料板压在布料的两侧。2. The two sides of the cloth are fixed by means of elastic force and gravity, which saves energy and has a simple structure. Specifically, under the elastic force of the elastic pressing component, the working end of the elastic pressing component and the upper end of the operating table abut each other, and the working The personnel adjust the horizontal position of the pressing plate at the top end of the elastic pressing component through the spacing adjustment component, so as to change the distance between a pair of pressing plates, so that the bottom end of the pressing plate can be pressed on both sides of the cloth. By controlling the vertical upward movement of the output end of the lifting component, the controller lifts the elastic pressing component, the spacing adjustment component and the pressing plate, so that the staff can easily load and unload the material. When the lifting component is released from the lifting action, under the action of gravity and elastic force, the pressing plate is pressed against both sides of the fabric.
3、通过设置防碳化机构，可以有效防止切口出现碳化现象，具体的，工作人员通过控制器发送信号给激光刀头、视觉拍摄机构和防碳化机构，激光刀头收到信号后对布料进行裁切，防碳化机构工作端朝向激光刀头切割布料位置并喷出氮气，防止切割缝出现碳化现象。3. By setting the anti-carbonization mechanism, the carbonization phenomenon of the incision can be effectively prevented. Specifically, the staff sends signals to the laser cutter head, the visual shooting mechanism and the anti-carbonization mechanism through the controller, and the laser cutter head cuts the fabric after receiving the signal. The working end of the anti-carbonization mechanism faces the cutting position of the laser cutter head and sprays nitrogen gas to prevent the carbonization of the cutting seam.

所述防碳化机构8为氮气保护装置，所述视觉拍摄机构7为CCD工业相机。工作人员先将成卷的物料安装到布料传输机构1的输入端上，然后再将物料另一端通过操作台2和工作箱3之间的间隙安装在布料传输机构1的输出端上。工作人员调节好压紧机构9两侧工作端之间的间距，然后压紧机构9工作端在重力和弹力的作用下自动下行将布料两侧压紧在操作台2上防止切割过程中布料发生褶皱影响切割效果。工作人员通过控制器发送信号给旋转机构4和直线移动机构5，旋转机构4收到信号后驱动直线移动机构5围绕旋转机构4的轴线做旋转运动，直线移动机构5收到信号后驱动激光刀头6、视觉拍摄机构7和防碳化机构8一同移动到工作初始位置。然后工作人员通过控制器发送信号给激光刀头6、视觉拍摄机构7和防碳化机构8，激光刀头6收到信号后对布料进行裁切，防碳化机构8工作端朝向激光刀头6切割布料位置并喷出氮气，防止切割缝出现碳化现象。视觉拍摄机构7实时进行拍照并将信号发送给控制器，控制器根据视觉拍摄机构7发来的图像作为旋转机构4和直线移动机构5工作的视觉辅助。控制器在视觉拍摄机构7的视觉辅助及预先设置好的移动轨迹来控制旋转机构4和直线移动机构5配合作业，从而使切割路径符合操作要求。旋转机构4和直线移动机构5相互配合可以取代传统的XY轴移动，更便于进行曲线切割。裁切完成后，控制器发送信号给激光刀头6和视觉拍摄机构7使其停止工作。然后控制器发送信号给布料传输机构1，布料传输机构1将裁切后的边角料收卷并使布料向布料传输机构1输出端方向运动从而进行第二次裁切作业。布料传输机构1还通过调整输入端与输出端之间的距离从而确保操作台2上方的布料始终处于张紧和水平的状态，使切割效果更好。The anti-carbonization mechanism 8 is a nitrogen protection device, and the visual photographing mechanism 7 is a CCD industrial camera. The staff first installs the rolled material on the input end of the cloth transmission mechanism 1, and then installs the other end of the material on the output end of the cloth transmission mechanism 1 through the gap between the operating table 2 and the work box 3. The staff adjusts the distance between the working ends on both sides of the pressing mechanism 9, and then the working ends of the pressing mechanism 9 automatically descend under the action of gravity and elastic force to press both sides of the cloth on the operating table 2 to prevent the occurrence of cloth during the cutting process. Folds affect the cut effect. The staff sends signals to the rotating mechanism 4 and the linear moving mechanism 5 through the controller. After the rotating mechanism 4 receives the signal, it drives the linear moving mechanism 5 to rotate around the axis of the rotating mechanism 4. After receiving the signal, the linear moving mechanism 5 drives the laser cutter head. 6. The visual photographing mechanism 7 and the anti-carbonization mechanism 8 move to the initial working position together. Then the staff sends signals to the laser cutter head 6, the visual photographing mechanism 7 and the anti-carbonization mechanism 8 through the controller, the laser cutter head 6 cuts the fabric after receiving the signal, and the working end of the anti-carbonization mechanism 8 cuts the fabric position toward the laser cutter head 6 and Nitrogen gas is sprayed to prevent carbonization of the cutting seam. The visual photographing mechanism 7 takes pictures in real time and sends a signal to the controller, and the controller uses the image sent by the visual photographing mechanism 7 as a visual aid for the work of the rotating mechanism 4 and the linear moving mechanism 5 . The controller controls the rotating mechanism 4 and the linear moving mechanism 5 to cooperate with the visual aid of the visual photographing mechanism 7 and the preset movement trajectory, so that the cutting path meets the operation requirements. The rotation mechanism 4 and the linear movement mechanism 5 cooperate with each other to replace the traditional XY axis movement, which is more convenient for curve cutting. After the cutting is completed, the controller sends a signal to the laser cutter head 6 and the visual photographing mechanism 7 to stop working. Then the controller sends a signal to the cloth transmission mechanism 1, and the cloth transmission mechanism 1 rewinds the cut leftovers and makes the cloth move toward the output end of the cloth transmission mechanism 1 to perform the second cutting operation. The cloth transmission mechanism 1 also ensures that the cloth above the operating table 2 is always in a state of tension and level by adjusting the distance between the input end and the output end, so that the cutting effect is better.

The feed roller 1a, the take-up roller 1b and the driven roller 1c are all rotatably connected through bearing seats and bearings provided at both ends. The tensioning assembly 1e is a ball screw slide table. At the same time, the reducer can increase the torque of the servo motor, and the worm gear reducer can also provide self-locking ability, which makes the control effect better.
