Description

Technical Field

[0001] The present invention relates to the technical field of dust-free cloth preparation, and in particular to a laser cutting device and method for preparing dust-free cloth. Background Art

[0002] Dust-free cloths, also known as clean wipes, are made of a double-woven 100% polyester fiber. Their soft surface makes them easy to wipe sensitive surfaces, without losing fibers. They also have excellent water absorption and cleaning efficiency. They are primarily used to clean high-tech products such as LCDs, wafers, PCBs, digital camera lenses, camera film, and optical discs without releasing dust particles. They can also absorb liquids and dust particles for cleaning purposes. When large pieces of dust-free cloth need to be cut into smaller pieces, laser cutting uses a high-temperature process to instantly melt them, ensuring a better edge seal at the cut portion, preventing lint from shedding. After cutting, the cloth can be rinsed and cleaned, achieving the highest dust-free standards. Currently, 75% of the dust-free cloth market uses laser cutting equipment for edge sealing.

[0003] In the process of cutting the dust-free cloth, the laser cutting device in the prior art usually directly lays a large piece of dust-free cloth flatly inside the laser cutting device, and uses a laser cutting head that moves back and forth to perform laser cutting on the dust-free cloth. Since the dust-free cloth is usually rolled up after preparation, the surface of the dust-free cloth on the outermost layer will inevitably be adhered to dust or other impurities during storage. If it is directly laid flat in the laser cutting device, the dust or other impurities adhered to the surface of the dust-free cloth will contaminate the laser cutting device and the dust-free cloth to be cut subsequently, thereby increasing the difficulty of subsequent dust-free cloth cleaning and reducing the efficiency of dust-free cloth preparation. Summary of the Invention

[0010] Optionally, a third sliding groove is provided on both side inner walls of the two movable seats, a third slider is installed inside the two third sliding grooves, and one end of the two third sliders away from the third sliding groove is connected to the movable plate close to it.

[0011] Optionally, a first groove is provided on the outer wall of the side where the two movable plates are close to each other, a first double-headed screw is rotatably installed inside the two first grooves, two first sliding blocks are installed on the outer walls of the two first double-headed screws, and both ends of the two rubber dust-sticking rollers are rotatably connected to the two first sliding blocks close to them.

[0012] Optionally, a fourth sliding groove is provided on the outer walls at both ends of the two rubber sticky rollers, a fourth slider is installed inside the two fourth sliding grooves, a first electric telescopic rod is installed on the outer wall of one side of the two fourth sliders, and an arc plate is installed on the telescopic end of the two first electric telescopic rods. The outer walls of the two rubber sticky rollers are provided with a storage groove connected to the two fourth sliding grooves, and the two arc plates are respectively stored in the corresponding storage grooves.

[0013] Optionally, the cleaning mechanism includes a second groove opened on the top of the fixed plate, a second double-headed screw is rotatably installed inside the second groove, two second sliding blocks are installed on the outer wall of the second double-headed screw, and a movable frame is installed on the top of the two second sliding blocks.

[0014] Optionally, two second electric telescopic rods are installed at the bottom of the two movable frames, and the telescopic ends of the two second electric telescopic rods are installed with nozzles that are compatible with the outer wall of the rubber sticky roller. The outer walls of the two nozzles on one side close to the rubber sticky roller are provided with multiple spray holes, and the outer walls of the two nozzles on one side close to the second electric telescopic rod are installed with connectors for connecting to external preset liquid spraying equipment.

[0015] Optionally, a laser cutting method for preparing a dust-free cloth includes the cutting device described above, and the cutting method further includes the following steps:

[0016] Step 1: Pull out one end of the dust-free cloth from the back of the device body and place it on top of one of the rubber sticky rollers. Control the two second electric telescopic rods to drive the two nozzles to press the dust-free cloth. As the two movable seats move from left to right, the dust-free cloth is spread out on the top of the conveyor belt. Control the telescopic ends of the two second electric telescopic rods to retract upward so that the two nozzles no longer press and fix one end of the dust-free cloth. One end of the dust-free cloth slides down from the surface of the rubber sticky roller to the top of the conveyor belt and is placed.

[0017] Step 2: After the dust-free cloth to be cut is laid flat on the top of the conveyor belt, the two third sliders are controlled to drive the two movable plates to move downward inside the two movable seats until the two rubber sticky rollers contact the dust-free cloth. Then, the two movable seats are controlled to move back and forth on the top of the device body, driving the two rubber sticky rollers to roll on the top of the conveyor belt, automatically flattening the dust-free cloth on the top of the conveyor belt;

[0018] Step 3: When the two movable seats drive the two rubber sticky rollers to move synchronously, if the dust-free cloth is skewed at this time, the two movable seats are controlled to drive the two rubber sticky rollers to move close to the skewed position of the dust-free cloth, and the two rubber sticky rollers are controlled to rotate and adjust together. Then, the two first electric telescopic rods are controlled to drive the two curved plates to extend downward together until the curved plates contact the dust-free cloth. Then, the corresponding fourth slider is controlled to drive the curved plates to move synchronously, so that the dust-free cloth with deviation in position can be pushed by the movement of the curved plates to ensure that the dust-free cloth is located in the center of the top of the conveyor belt.

[0019] Step 4: If there is a lot of dust or other impurities attached to the surface of the dust-free cloth to be cut, after the two movable seats drive the two rubber sticky rollers to pull the dust-free cloth to unfold above the conveyor belt, the telescopic ends of the two second electric telescopic rods are controlled to retract upward, and one end of the dust-free cloth is manually pulled to a limit, and then multiple second electric telescopic rods are controlled to drive multiple nozzles to press the dust-free cloth against the surface of the two rubber sticky rollers. Finally, the two movable seats are controlled to drive the two rubber sticky rollers to rub against the bottom of the dust-free cloth, and the dust or other impurities attached to the bottom of the dust-free cloth are automatically removed. Then, the multiple second electric telescopic rods are controlled to drive the multiple nozzles to release the pressing limit on the dust-free cloth, so that one end of the dust-free cloth slides down to the top of the conveyor belt and is placed. When the above-mentioned step of flattening the dust-free cloth is performed, the dust or other impurities attached to the top of the dust-free cloth are removed with the help of the two rubber sticky rollers.

[0020] Step 5: After the flattening, deviation correction and dust removal of the dust-free cloth are completed, the two first sliders are controlled to move inside the corresponding first slide groove, driving the top plate, processing head and other components to move together, and the laser cutting head and the external preset smoke removal equipment are controlled to start together, so that both smoke hoods generate suction. The laser cutting head moves back and forth on the top of the top plate through the processing head, and the two first sliders move inside the corresponding first slide groove, so that the laser cutting head can cut a whole piece of dust-free cloth into multiple parts of the same volume. The suction generated by the two smoke hoods can absorb the smoke generated by cutting.

[0021] The beneficial effects of the present invention are:

[0022] 1. In this invention, when dust or other impurities adhere to the surface of the dust-free cloth, the dust removal mechanism drives it to be pulled and unfolded above the conveyor belt, and then the bottom of the dust-free cloth is preferentially dusted by two rubber sticky rollers. Then, after the dust-free cloth is spread flat on the top of the conveyor belt, the top of the dust-free cloth is further dusted by two rubber sticky rollers, so as to prevent the dust or other impurities on the surface of the dust-free cloth from contaminating the conveyor belt and other subsequent dust-free cloths, thereby indirectly improving the efficiency of dust-free cloth preparation.

[0023] 2. In this invention, after the dust-free cloth to be cut is spread flat on the top of the conveyor belt, the two movable seats are controlled to drive the two rubber sticky rollers to remove dust from the top of the dust-free cloth. At the same time, the dust-free cloth on the top of the conveyor belt can be automatically flattened to ensure that there are no wrinkles on the surface of the dust-free cloth to be cut, which is convenient for the subsequent laser cutting head to cut the dust-free cloth.

[0024] 3. In the invention, when the two movable seats drive the two rubber sticky rollers to move synchronously, if the dust-free cloth located at the top of the conveyor belt is in a skewed state, the two movable seats are controlled to drive the two rubber sticky rollers to move close to the skewed position of the dust-free cloth, and the two rubber sticky rollers are controlled to rotate together, so that the fourth slide groove opened on the outer wall of the two rubber sticky rollers rotates to the bottom end, and then the arc plate is controlled to contact the dust-free cloth, and the corresponding fourth slider is controlled to drive the arc plate to move synchronously, so that the dust-free cloth with a deviation in position can be pushed at the top of the conveyor belt with the help of the movement of the arc plate, ensuring that the dust-free cloth is located in the center of the top of the conveyor belt, so that the subsequent laser cutting head can cut the dust-free cloth more accurately and reduce the generation of waste.

[0025] 4. In this invention, after the flattening, deviation correction and dust removal of the dust-free cloth are completed, the two first sliders are controlled to move inside the corresponding first slide groove toward the front of the device body, driving the top plate, processing head and other components to move together, and the laser cutting head and the external preset smoke removal equipment are controlled to start together, so that both smoke hoods generate suction. The laser cutting head can cut a whole piece of dust-free cloth into multiple parts of the same volume. The suction generated by the two smoke hoods can absorb the smoke generated by cutting, thereby preventing the smoke from escaping into the air and causing pollution to the environment around the device body.

[0040] Reference Figures 1-11, a laser cutting device for preparing dust-free cloth, includes a device body 1, the interior of the device body 1 is rotatably installed with a conveyor belt 2 through multiple drive shafts, a top plate 6 is arranged above the device body 1, a processing head 7 is slidably installed on the top of the top plate 6, a laser cutting head 14 is installed at the bottom end of the processing head 7, and both sides of the processing head 7 are equipped with a smoke removal mechanism for sucking out the smoke and dust generated during the laser cutting process, two movable seats 9 are slidably installed on the top of the device body 1, and a movable plate 20 is slidably installed on the side where the two movable seats 9 are close to each other, and two dust removal mechanisms for cleaning dust and impurities on the surface of the dust-free cloth to be cut are installed between the two movable plates 20, and the dust removal mechanism includes a rubber sticky roller 10 arranged between the two movable plates 20, and a fixed plate 15 is commonly installed on the top of the two movable plates 20, and a cleaning mechanism for removing the surfaces of the two rubber sticky rollers 10 is installed on the top of the fixed plate 15.

[0041] As a technical optimization solution of the present invention, first chutes 3 are provided on both sides of the outer wall of the device body 1. First sliders 11 are installed inside the two first chutes 3. A moving block 4 is installed on the end of the two first sliders 11 away from the first chutes 3. The top ends of the two moving blocks 4 are connected to the top plate 6 via a telescopic cylinder 5. First linear motors are pre-set inside the two first chutes 3. The two first linear motors can drive the two first sliders 11 to move back and forth within the corresponding first chutes 3, thereby driving the two moving blocks 4, the telescopic cylinder 5, and the top plate 6 to move synchronously, conveniently driving the processing head 7 to move back and forth on the top of the device body 1.

[0042] As a technical optimization solution of the present invention, the smoke removal mechanism includes two pipes 13, mounted on either side of the outer wall of the processing head 7. A fume hood 12 is mounted at the bottom end of each pipe 13, and each pipe 13 has a connection end for connecting to an external, pre-installed fume removal device. Before using the device 1, the input end of the external, pre-installed fume removal device can be connected to the top end of the two pipes 13 via two hoses. This allows the smoke generated during the operation of the laser cutting head 14 to be removed by the suction force generated by the two fume hoods 12, preventing the smoke from adversely affecting the environment surrounding the device 1.

[0043] As a technical optimization solution of the present invention, two second chutes 8 are defined at the top of the device body 1. Second sliders 18 are mounted within each of the second chutes 8. The tops of the two second sliders 18 are connected to the adjacent movable base 9. Second linear motors are pre-installed within each of the second chutes 8. These second linear motors can drive the two second sliders 18 to move back and forth within the corresponding second chutes 8, thereby driving the two movable bases 9 to move back and forth across the top of the device body 1.

[0044] As a technical optimization solution of the present invention, third chutes 19 are formed on the inner walls of both sides of the two movable seats 9. Third sliders 21 are installed inside the two third chutes 19. The ends of the two third sliders 21 away from the third chutes 19 are connected to the movable plate 20 adjacent to them. Third linear motors are pre-installed inside the two third chutes 19. The two third linear motors can drive the two third sliders 21 to move up and down within the corresponding third chutes 19, and in turn drive the corresponding movable plate 20 to move up and down together within the movable seat 9.

[0045] As a technical optimization solution of the present invention, the outer walls of the adjacent sides of the two movable plates 20 are each provided with a first groove 22. A first double-headed screw 24 is rotatably mounted inside each of the two first grooves 22. Two first sliding blocks 23 are mounted on the outer walls of each of the two first double-headed screws 24. The ends of the two rubber sticky rollers 10 are rotatably connected to the two adjacent first sliding blocks 23. A first drive device is pre-set inside each of the two movable plates 20. The output ends of the two first drive devices are respectively connected to one end of the two first double-headed screws 24, thereby driving the two first double-headed screws 24 to rotate within the corresponding first grooves 22. When the two first double-headed screws 24 rotate, they can drive the two first sliding blocks 23 on their outer walls to move toward or away from each other, thereby driving the two rubber sticky rollers 10 to move synchronously. A second drive device is pre-set inside each of the two first sliding blocks 23. The output ends of the two second drive devices are respectively connected to the rotating parts of the two rubber sticky rollers 10, thereby driving the two rubber sticky rollers 10 to rotate and adjust.

[0046] As a technical optimization solution of the present invention, the outer walls of both ends of the two rubber sticky rollers 10 are each provided with a fourth chute 25. A fourth slider 28 is mounted within each of the four chute 25. A first electric telescopic rod 29 is mounted on one side of the outer wall of each of the four sliders 28. A curved plate 27 is mounted at the telescopic end of each of the first electric telescopic rods 29. The outer walls of the two rubber sticky rollers 10 are each provided with a receiving groove 26 connected to the two fourth chute 25. The two curved plates 27 are respectively received within the corresponding receiving groove 26. A fourth linear motor is pre-installed within each of the four chute 25, which drives the two fourth sliders 28 to move back and forth within the corresponding fourth chute 25. Because the curved plate 27 is connected to one side of each of the four sliders 28 via the first electric telescopic rod 29, when the telescopic end of the first electric telescopic rod 29 extends, it drives the curved plate 27 out of the receiving groove 26, and the fourth slider 28 then drives the first electric telescopic rod 29 and the curved plate 27 to move.

[0047] As a technical optimization solution of the present invention, the cleaning mechanism includes a second groove 31 opened at the top of the fixed plate 15, a second double-headed screw 30 is rotatably installed inside the second groove 31, two second sliding blocks 32 are installed on the outer wall of the second double-headed screw 30, and a movable frame 16 is installed on the top of each of the two second sliding blocks 32. A third driving device is preset on the outside of one side of the fixed plate 15, and the output end of the third driving device is connected to one end of the second double-headed screw 30, so that the second double-headed screw 30 can be driven to rotate inside the second groove 31, so that the two second sliding blocks 32 can move toward or away from each other as the second double-headed screw 30 rotates, thereby driving the two movable frames 16 to move and adjust synchronously.

[0048] As a technical optimization of the present invention, two second electric telescopic rods 34 are mounted at the bottom of each of the two movable frames 16. The telescopic ends of each second electric telescopic rod 34 are each mounted with a nozzle 17 adapted to fit the outer wall of the rubber sticky roller 10. Multiple spray holes 35 are formed on the outer wall of each nozzle 17 on the side closest to the rubber sticky roller 10. A connector 33 for connecting to an external, pre-set liquid spray device is also mounted on the outer wall of each nozzle 17 on the side closest to the second electric telescopic rod 34. The telescopic ends of the second electric telescopic rod 34 extend and retract, driving the nozzle 17 to move up and down. The external, pre-set liquid spray device contains alcohol or other volatile cleaning agent. The connector 33 is connected to the output end of the liquid spray device via a hose, allowing the cleaning agent to be transported into the nozzle 17 and sprayed outward through the multiple spray holes 35 onto the surface of the rubber sticky roller 10 below, cleaning dust and impurities adhering to the surface of the rubber sticky roller 10 and facilitating subsequent use of the rubber sticky roller 10.

[0049] As a technical optimization solution of the present invention, a laser cutting method for preparing a dust-free cloth includes the cutting device described above, and the cutting method further includes the following steps:

[0050] Step 1: Pull out one end of the dust-free cloth on the back of the device body 1 and place it on top of one of the rubber sticky rollers 10. Control the two second electric telescopic rods 34 to drive the two nozzles 17 to press the dust-free cloth. As the two movable seats 9 move from left to right, the dust-free cloth is spread out on the top of the conveyor belt 2. Control the telescopic ends of the two second electric telescopic rods 34 to retract upward, so that the two nozzles 17 no longer press and fix one end of the dust-free cloth. One end of the dust-free cloth slides down from the surface of the rubber sticky roller 10 to the top of the conveyor belt 2 and is placed.

[0051] Step 2: After the dust-free cloth to be cut is laid flat on the top of the conveyor belt 2, the two third sliders 21 are controlled to drive the two movable plates 20 to move downward inside the two movable seats 9 until the two rubber sticky rollers 10 come into contact with the dust-free cloth. Then, the two movable seats 9 are controlled to move back and forth together on the top of the device body 1, driving the two rubber sticky rollers 10 to roll on the top of the conveyor belt 2, and automatically flattening the dust-free cloth on the top of the conveyor belt 2;

[0052] Step 3: In the process of the two movable seats 9 driving the two rubber sticky rollers 10 to move synchronously, if the position of the dust-free cloth is skewed at this time, the two movable seats 9 are controlled to drive the two rubber sticky rollers 10 to move close to the skewed position of the dust-free cloth, and the two rubber sticky rollers 10 are controlled to rotate and adjust together, and then the two first electric telescopic rods 29 are controlled to drive the two curved plates 27 to extend downward together until the curved plates 27 contact the dust-free cloth, and then the corresponding fourth sliders 28 are controlled to drive the curved plates 27 to move synchronously, so that the dust-free cloth with deviation in position can be pushed by the movement of the curved plates 27 to ensure that the dust-free cloth is located in the center of the top of the conveyor belt 2;

[0053] Step 4: If there is a lot of dust or other impurities attached to the surface of the dust-free cloth to be cut, after the two movable seats 9 drive the two rubber sticky rollers 10 to pull the dust-free cloth to unfold above the conveyor belt 2, the telescopic ends of the two second electric telescopic rods 34 are controlled to retract upward, and then one end of the dust-free cloth is manually pulled to a limit, and then the multiple second electric telescopic rods 34 are controlled to drive the multiple nozzles 17 to press the dust-free cloth against the surface of the two rubber sticky rollers 10, and finally, the two movable seats 9 are controlled to drive the two rubber sticky rollers 10 to rub against the bottom of the dust-free cloth, automatically adhering and removing the dust or other impurities attached to the bottom of the dust-free cloth, and then the multiple second electric telescopic rods 34 are controlled to drive the multiple nozzles 17 to release the pressing limit on the dust-free cloth, so that one end of the dust-free cloth slides down to the top of the conveyor belt 2 and is placed. When the above-mentioned step of flattening the dust-free cloth is performed, the dust or other impurities attached to the top of the dust-free cloth are again removed by means of the two rubber sticky rollers 10;

[0054] Step 5: After the flattening, deviation correction and dust removal of the dust-free cloth are completed, control the two first sliders 11 to move inside the corresponding first slide 3, driving the top plate 6, the processing head 7 and other components to move together, control the laser cutting head 14 and the external preset smoke removal equipment to start together, so that the two smoke extraction hoods 12 generate suction, the laser cutting head 14 moves back and forth on the top of the top plate 6 through the processing head 7, and the two first sliders 11 move inside the corresponding first slide 3, so that the laser cutting head 14 can cut a whole piece of dust-free cloth into multiple parts of the same volume, and the suction generated by the two smoke extraction hoods 12 can absorb the smoke generated by cutting.

[0055] In the present invention, when the user uses the device, Figure 1 As shown, at this time, the two movable seats 9 and the two rubber sticky rollers 10 are close to the back of the device body 1. One end of the dust-free cloth to be cut on the back of the device body 1 can be manually pulled out and placed on the top of one of the rubber sticky rollers 10, and the telescopic ends of the two second electric telescopic rods 34 above the rubber sticky roller 10 are controlled to extend downward together, driving the two nozzles 17 to press the dust-free cloth placed on the top of one of the rubber sticky rollers 10. As the two movable seats 9 move from left to right on the top of the device body 1, the dust-free cloth is spread out on the top of the conveyor belt 2 until the dust-free cloth is spread out to a sufficient length. It is cut with the help of an external preset shearing device, and the telescopic ends of the two corresponding second electric telescopic rods 34 are controlled to retract upward, so that the two nozzles 17 no longer press and fix one end of the dust-free cloth, and one end of the dust-free cloth slides down from the surface of the rubber sticky roller 10 to the top of the conveyor belt 2, thereby achieving the effect of automatically spreading the dust-free cloth to be cut on the top of the conveyor belt 2.

[0056] After the dust-free cloth to be cut is spread flat on the top of the conveyor belt 2, in order to facilitate the subsequent laser cutting head 14 to cut the dust-free cloth, the two third sliders 21 can be controlled to move downward together inside the corresponding third slide groove 19, and the two movable plates 20 can be driven to move downward inside the two movable seats 9 until the two rubber sticky rollers 10 contact the dust-free cloth on the top of the conveyor belt 2. Then, the two movable seats 9 are controlled to move back and forth together on the top of the device body 1, so that the two rubber sticky rollers 10 can be driven to roll on the top of the conveyor belt 2, and the dust-free cloth on the top of the conveyor belt 2 is automatically flattened to ensure that there are no wrinkles on the surface of the dust-free cloth to be cut, which facilitates the subsequent laser cutting head 14 to cut the dust-free cloth.

[0057] At the same time, when the two movable seats 9 drive the two rubber sticky rollers 10 to move synchronously, if the position of the dust-free cloth at the top of the conveyor belt 2 is skewed, the two movable seats 9 can be controlled to drive the two rubber sticky rollers 10 to move close to the skewed position of the dust-free cloth, and the two rubber sticky rollers 10 can be controlled to rotate together, so that the fourth slide 25 opened on the outer wall of the two rubber sticky rollers 10 rotates to the bottom end, and then the telescopic ends of the two first electric telescopic rods 29 are controlled to extend downward together, driving the two curved plates 27 to extend downward from the inside of the corresponding storage groove 26 until the curved plates 27 contact the dust-free cloth, and then the corresponding fourth sliders 28 are controlled to move and adjust inside the fourth slide 25, thereby driving the curved plates 27 to move synchronously, so that the dust-free cloth with deviation in position can be pushed at the top of the conveyor belt 2 by means of the movement of the curved plates 27, ensuring that the dust-free cloth is located in the center of the top of the conveyor belt 2, so that the subsequent laser cutting head 14 can cut the dust-free cloth more accurately and reduce the generation of waste.

[0058] Moreover, if there is a lot of dust or other impurities attached to the surface of the dust-free cloth to be cut, in order to prevent these dust or other impurities from falling on the surface of the conveyor belt 2 and affecting the subsequent use of the conveyor belt 2, the two movable seats 9 can be used to drive the two rubber sticky rollers 10 to pull the dust-free cloth to unfold above the conveyor belt 2. At this time, the two movable seats 9 are close to the front of the device body 1, and the telescopic ends of the two corresponding second electric telescopic rods 34 are controlled to retract upward. Then, the end of the dust-free cloth originally pressed by the two nozzles 17 and the rubber sticky roller 10 is pulled and limited by manual or pre-set clamping devices on the front of the device body 1, and then the telescopic ends of the multiple second electric telescopic rods 34 are controlled to extend downward together, driving the multiple nozzles 17 to press the dust-free cloth against the surfaces of the two rubber sticky rollers 10 together, and ensuring that the pressure of the multiple nozzles 17 on the dust-free cloth is relatively loose, and finally the two movable seats 9 are controlled to retract from the device body The front of the body 1 moves toward the back, driving the two rubber sticky rollers 10 to rub against the bottom of the dust-free cloth, automatically removing the dust or other impurities attached to the bottom of the dust-free cloth. After the dust or other impurities on the bottom of the dust-free cloth are removed, the two movable seats 9 and other components are located at one end of the dust-free cloth, controlling the telescopic ends of the multiple second electric telescopic rods 34 to retract upward together, driving the multiple nozzles 17 to release the pressing limit on the dust-free cloth, so that one end of the dust-free cloth slides down to the top of the conveyor belt 2 and is placed there. Then, when the above-mentioned step of flattening the dust-free cloth is performed, the two rubber sticky rollers 10 are in friction contact with the top of the dust-free cloth, and the two rubber sticky rollers 10 can be used to remove the dust or other impurities attached to the top of the dust-free cloth, thereby achieving the effect of comprehensively cleaning the surface of the dust-free cloth and reducing the problem of the dust-free cloth with a lot of dust or other impurities attached to the surface causing pollution to the conveyor belt 2.

[0059] After the flattening, deviation correction and dust removal of the dust-free cloth are completed, the two first sliders 11 can be controlled to move inside the corresponding first slide 3 toward the front of the device body 1, driving the top plate 6, the processing head 7 and other components to move together, and the laser cutting head 14 and the external preset smoke removal equipment are controlled to start together, so that the two smoke hoods 12 generate suction. The laser cutting head 14 can move back and forth on the top of the top plate 6 through the processing head 7, and the movement of the two first sliders 11 inside the corresponding first slide 3, so that the laser cutting head 14 can cut a whole piece of dust-free cloth into multiple parts of the same volume. The suction generated by the two smoke hoods 12 can absorb the smoke generated by cutting, thereby preventing the smoke from escaping into the air and causing pollution to the environment around the device body 1.

[0060] After a whole piece of dust-free cloth is cut into multiple small pieces of the same size, there will be waste at the four edge positions of the original whole piece of dust-free cloth. The two rubber sticky rollers 10 can be controlled to rotate to ensure that the fourth slide groove 25 is at the bottom end, and the waste of the dust-free cloth close to the front of the device body 1 is lifted up. Then, the telescopic ends of the multiple first electric telescopic rods 29 are controlled to extend together, pushing the multiple curved plates 27 to extend downward from the corresponding storage grooves 26, so that the multiple extended curved plates 27 can abut against the edge waste of the dust-free cloth after being lifted and folded upward. Then, the two movable seats 9 are controlled to move toward the back of the device body 1. With the help of the multiple curved plates 27, the edge waste of the dust-free cloth can be pushed off from the top of the conveyor belt 2 first, thereby achieving the effect of automatically removing waste.

[0061] After the edge waste of the dust-free cloth is removed, only multiple pieces of cut dust-free cloth of the same volume remain on the top of the conveyor belt 2. By controlling the rotation of the conveyor belt 2, the multiple dust-free cloths can be driven to be transported downward from the front of the device body 1 to the inside of the preset collection container, thereby achieving the effect of automatically collecting the multiple pieces of cut dust-free cloth.

[0062] As mentioned above, after the laser cutting head 14 cuts the dust-free cloth, if a small amount of the cut part of the dust-free cloth is found to be stuck, the two movable seats 9 can be controlled to drive the two rubber sticky rollers 10 to move close to the two dust-free cloths with adhesion before controlling the conveyor belt 2 to rotate to convey the cut dust-free cloth. The two first double-headed screws 24 can be controlled to rotate to drive the two corresponding first sliding blocks 23 to move in the direction of approaching each other. At the same time, the two rubber sticky rollers 10 can be driven to move in the direction of approaching each other to the specified position. At this time, the two rubber sticky rollers 10 are still on the two sides. Above the two adhered dust-free cloths, the two movable plates 20 drive the two rubber sticky rollers 10 to move downward together, so that the two rubber sticky rollers 10 can respectively press and fix the two adhered dust-free cloths, and then the two first double-headed screws 24 can be controlled to reverse, driving the two rubber sticky rollers 10 to move away from each other, and driving the two adhered dust-free cloths to be pulled, so that the two dust-free cloths can be automatically separated, which is convenient for subsequent cleaning of the dust-free cloths and other operations. There is no need to spend a lot of time manually pulling and separating them, thereby improving the preparation efficiency of the dust-free cloths.

[0063] If the conveyor belt 2 malfunctions during use, resulting in the inability to automatically convey and discharge the cut dust-free cloths downward, at this time, the two movable seats 9 can be controlled to drive the two rubber sticky rollers 10 to move to a position close to the back of the device body 1, and the two movable plates 20 can be controlled to drive the two rubber sticky rollers 10 to move downward together until they are in contact with the conveyor belt 2. As the two movable seats 9 move toward the front of the device body 1, the two rubber sticky rollers 10 are driven to push the dust-free cloths on the top of the conveyor belt 2 to move together until the multiple dust-free cloths cut from the top of the conveyor belt 2 are pushed down to the bottom of the device body 1, thereby automatically unloading the multiple cut dust-free cloths instead of the conveyor belt 2, avoiding the problem that the multiple cut dust-free cloths cannot be automatically unloaded after the conveyor belt 2 is damaged, thereby improving the applicability of the two rubber sticky rollers 10.

[0064] When it is found that there is a lot of dust or other impurities attached to the surfaces of the two rubber sticky rollers 10, the telescopic ends of the multiple second electric telescopic rods 34 can be controlled to extend downward together, driving the multiple nozzles 17 to respectively abut the outer walls of the two rubber sticky rollers 10, and controlling the external preset liquid spraying device to start, so that the cleaning agent is sprayed onto the surfaces of the two rubber sticky rollers 10 through the multiple nozzles 35, and the surfaces of the two rubber sticky rollers 10 can be automatically cleaned. While the cleaning agent is sprayed onto the surfaces of the two rubber sticky rollers 10, the two rubber sticky rollers 10 are controlled to rotate synchronously, and the second double-headed screw 30 is controlled to rotate, driving the two movable frames 16 to move synchronously, and the corresponding two nozzles 17 can also be driven to move back and forth on the surfaces of the two rubber sticky rollers 10, so that the cleaning agent is comprehensively sprayed onto the surfaces of the two rubber sticky rollers 10, and the surfaces of the two rubber sticky rollers 10 are scraped, so as to automatically clean and remove the dust or other impurities on the surfaces of the two rubber sticky rollers 10, and facilitate the subsequent use of the two rubber sticky rollers 10.
