Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent laser cutting devices, and particularly relates to an intelligent laser cutting device and method based on glass fiber cloth production. BACKGROUND

[0002] In the production process of glass fiber cloth, laser cutting is a key process for realizing the sizing processing and special-shaped profile forming of glass fiber cloth. With the increasing requirements of downstream applications on the cutting precision and edge quality (such as the width of the melting zone needs to be controlled within a certain limit) of glass fiber cloth, and the development of production lines towards high speed and continuity, the existing intelligent laser cutting device based on glass fiber cloth production still has the following defects in use: Firstly, the existing intelligent laser cutting device is designed for fixed specifications of glass fiber cloth, and does not fully consider the objective situation that the fiber weaving density of different batches or even the same roll of material has certain differences due to the weaving process fluctuations (such as warp and weft yarn tension deviation and loom speed fluctuation), and usually uses preset fixed laser power and cutting speed parameters; when cutting the area with high fiber density, the fixed power is difficult to meet the energy demand of complete fiber cutting, and the cutting is not complete, which needs to be manually cut again, which not only increases the production process, but also reduces the overall production efficiency. Secondly, when cutting the area with low fiber density, the fixed laser power will cause excessive melting of the edge fibers of the glass fiber cloth due to energy surplus, forming a large melting zone. The melting zone will damage the interfacial bonding performance between the glass fiber cloth and the resin, resulting in a significant decrease in the interlaminar peel strength of the subsequent composite material, which cannot meet the requirements of high-end composite materials on the bonding performance of the base material.

DETAILED DESCRIPTION

[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0021] Embodiment 1: see Figures 1-3 The intelligent laser cutting device based on glass fiber cloth production shown in the figure comprises a winding device 1 for conveying glass fiber cloth; a laser cutting device is arranged on the winding device 1; a fiber density detection mechanism 2, a laser cutting parameter dynamic controller and a laser cutting execution adjustment mechanism 3 are arranged on the winding device 1; the fiber density detection mechanism 2 comprises an upper detection air duct 22, a lower detection air duct 23, an air pressure sensor 24 and a tension adjusting mechanism 27; wherein an air pump is arranged on the winding device 1, a quantitative air inlet pipeline 21 is arranged on the winding device 1, and the output end of the air pump is connected with the quantitative air inlet pipeline 21; the upper detection air duct 22 is arranged on the winding device 1, the input end of the upper detection air duct 22 is connected with the quantitative air inlet pipeline 21, and the output end of the upper detection air duct 22 is vertically close to the top of the glass fiber cloth; a mounting bracket is arranged on the winding device 1, the lower detection air duct 23 is arranged on the mounting bracket, and the inlet and outlet ends of the lower detection air duct 23 are vertically close to the bottom of the glass fiber cloth; the air pressure sensor 24 is arranged on the lower detection air duct 23, and the detection end of the air pressure sensor 24 is inserted into the lower detection air duct 23; the tension adjusting mechanism 27 is arranged on the winding device 1 and is used for controlling the tension of the glass fiber cloth conveying; the laser cutting parameter dynamic controller is arranged in an electrical control cabinet of the winding device 1 and is used for receiving and analyzing the detection data of the air pressure sensor 24, so as to adapt the laser power and the cutting speed to the current density of the glass fiber cloth and generate a parameter adjustment instruction; the laser cutting execution adjustment mechanism 3 is arranged between the winding device 1 and the laser cutting device and is used for receiving the parameter adjustment instruction of the laser cutting parameter dynamic controller, so as to control the cutting speed of the laser cutting device and the moving speed of the laser head along the width direction of the glass fiber cloth.

[0022] It should be noted that after the winding device 1 is started, the glass fiber cloth is continuously conveyed along the preset direction, the air pump equipped on the winding device 1 is started synchronously, the high-pressure air source generated by the air pump is conveyed to the upper detection air duct 22 through the quantitative air inlet pipeline 21; the upper detection air duct 22 and the lower detection air duct 23 form an up-down aligned air duct structure; after the quantitative air flow is output from the upper detection air duct 22, it penetrates the glass fiber cloth vertically and enters the lower detection air duct 23, during which the fiber density of the glass fiber cloth will generate different resistance to the air flow, and the air flow resistance is detected in real time through the air pressure sensor 24, the air pressure signal is converted into the corresponding fiber density value, and then the density value is transmitted to the laser cutting parameter dynamic controller. After the laser cutting parameter dynamic controller receives the density data, the laser power and cutting speed instructions adapted to the current density are generated, and the instructions are further transmitted to the laser cutting execution adjustment mechanism 3, and the laser cutting execution adjustment mechanism 3 drives the laser cutter to perform the cutting action according to the instructions, while the winding device 1 continuously conveys the glass fiber cloth, realizing continuous cutting; Through the cooperation of the fiber density detection mechanism 2, the laser cutting parameter dynamic controller and the laser cutting execution adjustment mechanism 3, the defects of the existing device using fixed parameters for cutting are solved; the upper detection air duct 22 and the lower detection air duct 23 are aligned, which ensures that the air flow penetrates the glass fiber cloth vertically, the air pressure sensor 24 can accurately capture the difference in air flow resistance corresponding to different fiber densities, so that the density detection result always maintains high accuracy, avoiding parameter adjustment errors caused by detection deviation. The laser cutting parameter dynamic controller dynamically adjusts the parameters according to the real-time density data, no longer relying on fixed values, which can effectively avoid the problems of incomplete cutting when the fiber density is too high and excessive melting of the edge when the density is too low, and at the same time, combined with the continuous conveying of the winding device 1, it meets the high-speed demand of the production line, significantly improves the cutting quality and production efficiency.

[0023] Please refer to Figure 3 The first air volume adjusting valve 25 is arranged on the quantitative air inlet pipeline 21 and is used to control the air volume introduced into the upper detection air duct 22.

[0024] It should be noted that after the air pump is started, the air flow first passes through the first air volume adjusting valve 25 and then enters the quantitative air inlet pipeline 21, and the operator can control the air volume introduced into the upper detection air duct 22 by adjusting the opening of the first air volume adjusting valve 25 according to the basic thickness of the glass fiber cloth and the production environment. When the output pressure of the air pump fluctuates slightly, the first air volume adjusting valve 25 can automatically compensate for the pressure change, ensuring that the air flow entering the upper detection air duct 22 always maintains a quantitative state, so that the air flow resistance data detected by the air pressure sensor 24 after the subsequent air flow penetrates the glass fiber cloth is more stable, and the density value transmitted to the laser cutting parameter dynamic controller is further improved in accuracy.

[0025] Please refer to Figures 1-2The tension adjusting mechanism 27 comprises a power roller 271, an adjusting roller 272, a sliding groove 273 and a pneumatic cylinder 274. The power roller 271 and the adjusting roller 272 are arranged on the winding device 1. When the power roller 271 rotates, the glass fiber fabric is driven by the cooperation of the adjusting roller 272. The sliding groove 273 is arranged on both sides of the winding device 1, and the two ends of the adjusting roller 272 are slidingly connected to the sliding grooves 273. The pneumatic cylinder 274 is installed on the winding device 1, and the output end of the pneumatic cylinder 274 is connected with the adjusting roller 272, and is used for driving the end of the adjusting roller 272 to slide in the sliding groove 273, so as to adjust the distance between the power roller 271 and the adjusting roller 272.

[0026] It should be noted that the winding device 1 is started, and the tension adjusting mechanism 27 is synchronously put into work. The power roller 271 rotates under the driving of the driving assembly, and the glass fiber fabric is clamped and driven to move along the conveying path of the winding device 1 by the cooperation of the adjusting roller 272. When the tension sensor on the winding device 1 detects that the tension of the glass fiber fabric deviates from the preset range, the pneumatic cylinder 274 drives the end of the adjusting roller 272 to slide up and down in the sliding groove 273, so as to change the distance between the power roller 271 and the adjusting roller 272. When the distance increases, the tension of the glass fiber fabric decreases; when the distance decreases, the tension of the glass fiber fabric increases, so that the glass fiber fabric always maintains the preset tension during the conveying process, and the adhesion degree of the glass fiber fabric to the upper detection air duct 22 and the lower detection air duct 23 is stable, and a flat base material is provided for subsequent laser cutting.

[0027] Please refer to Figure 1 and Figure 4 The fiber density detection mechanism 2 further comprises a laser head lens dust cleaning mechanism 26 arranged on the laser head of the laser cutter on the winding device 1. The laser head lens dust cleaning mechanism 26 is used for generating an air flow at the position of the laser head lens, so as to clean the dust on the laser head lens.

[0028] It should be noted that when the laser cutter starts the cutting action, the laser head lens dust cleaning mechanism 26 arranged on the laser head of the laser cutter is synchronously started. The laser head lens dust cleaning mechanism 26 generates a directional air flow at the position of the laser head lens through linkage with the air pump on the winding device 1. When the laser cutting of the glass fiber fabric generates glass fiber dust, the air flow directly acts on the surface of the laser head lens, blows the dust attached to the lens away from the lens area, and avoids the accumulation of dust on the surface of the lens. During the whole cutting process, the laser head lens dust cleaning mechanism 26 continuously works, and always maintains the clean state of the laser head lens, so as to ensure that the laser beam can be normally focused through the lens and act on the surface of the glass fiber fabric.

[0029] Please refer to Figure 4 and Figures 6-9The laser head lens dust cleaning mechanism 26 comprises a wind guide 261, a connecting pipe 264, a spring hose 266 and a plurality of spray heads 263. The wind guide 261 covers the laser head of the laser cutting device, and the wind guide 261 is connected with the laser head through a flange. An annular air curtain air duct 262 is formed on the inner wall of the wind guide 261. The plurality of spray heads 263 are arranged on the inner wall of the wind guide 261 at equal intervals around the axis of the wind guide 261. The connecting pipe 264 is arranged on the wind guide 261, and one end of the connecting pipe 264 is connected with the quantitative air inlet pipe 21 through the spring hose 266. The connecting pipe 264 is communicated with the plurality of spray heads 263 through the annular air curtain air duct 262. The outlet of the spray head 263 is inclined downward, so that the air flow discharged through the outlet of the spray head 263 spirally flows downward along the inner wall of the wind guide 261. The second air volume adjusting valve 265 is arranged on the connecting pipe 264 and is used for controlling the air volume introduced into the connecting pipe 264.

[0030] It should be noted that the air flow generated by the air pump on the winding device 1 is divided through the quantitative air inlet pipe 21, then is transported to the connecting pipe 264 through the spring hose 266, and the connecting pipe 264 introduces the air flow into the annular air curtain air duct 262 formed on the inner wall of the wind guide 261. The annular air curtain air duct 262 uniformly distributes the air flow to the plurality of spray heads 263. The outlet of the spray head 263 is inclined downward, so that the discharged air flow spirally flows downward along the inner wall of the wind guide 261, forming an annular air curtain. The laser head lens is cleaned, and the annular air curtain does not directly contact the surface of the laser head lens, so as not to interfere with the laser. The operator can adjust the second air volume adjusting valve 265 on the connecting pipe 264 to control the air volume introduced into the connecting pipe 264, and then adjust the intensity of the air flow discharged by the spray head 263, so as to adapt to the dust production amount in different cutting scenes.

[0031] Please refer to Figures 4-5 The synchronous control mechanism 267 is arranged on the laser cutting execution adjusting mechanism 3. When the laser cutting device cuts the glass fiber cloth, the synchronous control mechanism 267 is used to drive the connecting pipe 264 to move synchronously.

[0032] It should be noted that when the laser cutting execution adjusting mechanism 3 drives the laser cutting device to move along the X axis, i.e. along the width direction of the glass fiber cloth, the synchronous control mechanism 267 installed on the laser cutting execution adjusting mechanism 3 is started synchronously. The synchronous control mechanism 267 receives the movement signal from the laser cutting execution adjusting mechanism 3, and drives the connecting pipe 264 to move synchronously along the same direction with the laser cutting device. Since the connecting pipe 264 is connected with the moving part of the synchronous control mechanism 267, and the connecting pipe 264 is connected with the quantitative air inlet pipe 21 through the spring hose 266, the spring hose 266 can be adaptively stretched or bent during the synchronous movement, so as to ensure that the air flow transportation is not interrupted, and at the same time, the wind guide 261 is always covered on the laser head, and the annular air curtain continuously acts on the lens surface. The arrangement of the synchronous control mechanism 267 solves the problem that the dust removal mechanism cannot follow when the laser head moves; through the synchronous movement of the connecting pipe 264, it can be ensured that the air duct 261 always remains relatively fixed with the laser head, and the annular air curtain always accurately covers the surface of the lens, avoiding the situation that the airflow deviates and the dust removal fails due to the movement of the laser head.

[0033] Please refer to Figures 4-6 It can be understood that the specific structure and installation method of the synchronous control mechanism 267 are not limited in the present application, and only one feasible technical solution is provided below; the synchronous control mechanism 267 includes a sliding rail 2671, a sliding block 2672, a mounting block 2673, a threaded seat 2674, a motor 2675, and a threaded rod 2676; the sliding rail 2671 is fixedly arranged on the winding device 1, and the length direction of the sliding rail 2671 is parallel to the movement direction of the laser cutter along the X-axis; the sliding block 2672 is slidingly connected to the sliding rail 2671, the connecting pipe 264 is fixedly arranged on the sliding block 2672 through the mounting block 2673, and the threaded seat 2674 is fixedly arranged on the sliding block 2672; the threaded rod 2676 is rotationally connected to the sliding rail 2671 about its axis, and the threaded seat 2674 is threadedly sleeved on the threaded rod 2676; the motor 2675 is installed on the laser cutting execution adjustment mechanism 3, and the output end of the motor 2675 is coaxially connected with the threaded rod 2676.

[0034] It should be noted that when the laser cutting execution adjustment mechanism 3 drives the laser cutter to move along the X-axis, the motor 2675 installed on the laser cutting execution adjustment mechanism 3 is started, and the output end of the motor 2675 drives the threaded rod 2676 to rotate about its axis; the threaded rod 2676 threadedly cooperates with the threaded seat 2674 fixedly arranged on the sliding block 2672, and when the threaded rod 2676 rotates, it drives the threaded seat 2674 to drive the sliding block 2672 to slide along the sliding rail 2671; the connecting pipe 264 is fixedly arranged on the sliding block 2672 through the mounting block 2673, so that when the sliding block 2672 slides, it drives the connecting pipe 264 to move synchronously, and then drives the air duct 261 to move synchronously along the X-axis with the laser head, thereby realizing the accurate synchronization of the dust removal mechanism and the laser head.

[0035] Please refer to Figures 1-2 The dust collection hopper 268 is arranged on the winding device 1, and the dust collection hopper 268 is arranged below the lower detection air duct 23, and the bottom end of the lower detection air duct 23 is inserted into the bottom discharge port of the dust collection hopper 268.

[0036] It should be noted that during the laser cutting process, the dust blown away by the lens dust removal mechanism 26 of the laser head falls downward under the action of gravity and airflow guidance, and the dust generated when the lower detection air duct 23 discharges the airflow carrying the penetrated fiberglass cloth also enters the dust collection hopper 268. The bottom discharge port of the dust collection hopper 268 forms a negative pressure through the airflow discharged by the lower detection air duct 23, which facilitates the rapid discharge of dust.

[0037] Please refer to Figures 1-2 It can be understood that the specific structure and installation method of the laser cutting execution adjustment mechanism 3 are not limited in the present application, and only one possible technical solution is provided below; the laser cutting execution adjustment mechanism 3 includes an X-axis linear module 31 and a Y-axis linear module 32; the Y-axis linear module 32 is installed on the winding device 1 and is used to control the movement of the laser cutter along the Y-axis; the X-axis linear module 31 is installed on the Y-axis linear module 32, and the laser cutter is installed on the X-axis linear module 31; the X-axis linear module 31 is used to control the movement of the laser cutter along the X-axis.

[0038] It should be noted that the Y-axis linear module 32 drives its moving part to move along the Y-axis, i.e., along the direction of the glass fiber cloth conveying direction, according to the instruction, to adjust the cutting speed of the laser cutter in the conveying direction; at the same time, the X-axis linear module 31 installed on the Y-axis linear module 32 drives its moving part to move along the X-axis, i.e., along the width direction of the glass fiber cloth, according to the instruction, and the laser cutter is installed on the moving part of the X-axis linear module 31, so the X-axis linear module 31 can adjust the moving speed and position of the laser cutter in the width direction. Through the coordinated movement of the X-axis linear module 31 and the Y-axis linear module 32, the laser cutter can perform cutting action according to the preset trajectory and speed, and cooperate with the continuous conveying of the winding device 1 to complete the accurate cutting of the glass fiber cloth.

[0039] Embodiment 2: The technical solution of the present embodiment is different from that of Embodiment 1 in that: please refer to Figures 1-10 An intelligent laser cutting method based on glass fiber cloth production uses the above-mentioned intelligent laser cutting device based on glass fiber cloth production; specifically including the following steps: Step one, density detection: the quantitative air flow of the high-pressure air source generated by the air pump enters the upper detection air duct 22 through the quantitative air inlet pipeline 21, passes through the glass fiber cloth, and is discharged through the lower detection air duct 23, at which time the air pressure sensor 24 detects the air flow resistance, matches the corresponding glass fiber cloth fiber density according to the air flow resistance data, converts the air pressure signal into the corresponding fiber density value, and transmits it to the laser cutting parameter dynamic controller; it can be understood that the data relationship between air flow resistance and glass fiber cloth fiber density is obtained through multiple tests; Step two, cutting parameter control: receive real-time density data of glass fiber cloth fiber density, match corresponding laser power and cutting speed according to density data, generate parameter adjustment instruction, and transmit it to the laser cutting execution adjustment mechanism 3; it can be understood that the data relationship between glass fiber cloth fiber density and laser power and cutting speed is obtained through multiple tests; Step three, laser cutting adjustment: receive the parameter adjustment instruction of the laser cutting parameter controller, control the cutting speed and adjust the moving speed of the laser head along the width direction of the glass fiber cloth according to the parameter adjustment instruction.
