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 cloth, also known as dust-free wiping cloth, is made of 100% polyester fiber double weave. It has a soft surface, is easy to wipe sensitive surfaces, does not lose fibers when rubbed, and has good water absorption and cleaning efficiency. It is mainly used to wipe high-tech products such as LCD, wafer, PCB, digital camera lens, camera film and optical disc without generating dust particles. It can also absorb liquid and dust particles to achieve a cleaning effect. When a large piece of dust-free cloth needs to be divided into multiple small pieces, it is instantly melted by laser cutting at high temperature, so that the cutting part of the dust-free cloth is better sealed and does not produce lint. After cutting, it can be cleaned by net rinsing and washing, so that the product can reach a higher dust-free standard. At present, 75% of the market uses laser cutting devices to cut and seal the dust-free cloth.

[0003] In the process of cutting the dust-free cloth, the laser cutting device in the prior art usually directly spreads a large piece of dust-free cloth 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 outermost dust-free cloth will inevitably be adhered to dust or other impurities during storage. If the dust-free cloth is directly spread inside 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 cleaning of the dust-free cloth and reducing the efficiency of dust-free cloth preparation.

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

[0016] Step 1: Pull out one end of the dust-free cloth on the back of the device body and place it on the top of one of the rubber dust-sticking rollers, control the two second electric telescopic rods to drive the two nozzles to press the dust-free cloth, and as the two moving seats move from left to right, drive the dust-free cloth to be 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, and one end of the dust-free cloth slides down from the surface of the rubber dust-sticking roller to the top of the conveyor belt for placement;

[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 moving plates to move downward inside the two moving seats until the two rubber sticky rollers are in contact with the dust-free cloth, and then the two moving 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, and the dust-free cloth on the top of the conveyor belt is automatically flattened;

[0018] Step 3: In the process of the two moving seats driving the two rubber dust-sticking rollers to move synchronously, if the dust-free cloth is in a skewed state at this time, the two moving seats are controlled to drive the two rubber dust-sticking rollers to move close to the skewed position of the dust-free cloth, and the two rubber dust-sticking rollers are controlled to rotate and adjust together, and then the two first electric telescopic rods are controlled to drive the two arc plates to extend downward together until the arc plates contact the dust-free cloth, and the corresponding fourth slider is controlled to drive the arc plates to move synchronously, so that the dust-free cloth with a deviation in position can be pushed by the movement of the arc 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 rubber sticky rollers are driven by the two movable seats 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 limit the position, and then the multiple second electric telescopic rods are controlled to drive the multiple nozzles to press the dust-free cloth on the surface of the two rubber sticky rollers, and 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 adhered and removed, and 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, and when the above step of flattening the dust-free cloth is performed, the dust or other impurities attached to the top of the dust-free cloth are adhered and 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 grooves, driving the top plate, the 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 the two smoke extraction 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 grooves, 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 extraction hoods can absorb the smoke generated by the cutting.

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

[0022] 1. In the present invention, when dust or other impurities are attached to the surface of the dust-free cloth, the dust-free cloth is pulled and unfolded above the conveyor belt by means of a dust removal mechanism, and then the bottom of the dust-free cloth is firstly dusted by two rubber dust-sticky rollers. Then, after the dust-free cloth is spread on the top of the conveyor belt, the top of the dust-free cloth is further dusted by two rubber dust-sticky rollers, so as to avoid 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 the present invention, after the dust-free cloth to be cut is spread on the top of the conveyor belt, the two movable seats are controlled to drive the two rubber dust-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, in the process of two movable seats driving two rubber sticky rollers to move synchronously, if the position of the dust-free cloth located at the top of the conveyor belt 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 together, so that the fourth slide groove opened on the outer wall of the two rubber sticky rollers rotates to the bottom, and then the arc plate is controlled to contact with 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 the 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 grooves toward the front side close to the device body, driving the top plate, the 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 the two smoke extraction hoods can 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 extraction hoods can absorb the smoke generated by the cutting, thereby preventing the smoke from escaping into the air and causing pollution to the environment around the device body.

[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 the top of one of the rubber dust-sticking rollers 10, control the two second electric telescopic rods 34 to drive the two nozzles 17 to press the dust-free cloth, and as the two moving seats 9 move from left to right, drive the dust-free cloth to be 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, and one end of the dust-free cloth slides down from the surface of the rubber dust-sticking roller 10 to the top of the conveyor belt 2 for placement;

[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 dust-sticking rollers 10 are in contact with the dust-free cloth, and 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 dust-sticking rollers 10 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;

[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 rubber sticky rollers 10 are driven by the two movable seats 9 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 one end of the dust-free cloth is manually pulled to limit the position, and then the multiple second electric telescopic rods 34 are controlled to drive the multiple nozzles 17 to press the dust-free cloth on 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, and the dust or other impurities attached to the bottom of the dust-free cloth are automatically removed by adhesion, 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.

[0056] After the dust-free cloth to be cut is spread 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 are 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, so as to facilitate the subsequent laser cutting head 14 to cut the dust-free cloth.

[0057] At the same time, in the process of the two moving seats 9 driving the two rubber dust-sticking rollers 10 to move synchronously, if the position of the dust-free cloth at the top of the conveyor belt 2 is skewed at this time, the two moving seats 9 can be controlled to drive the two rubber dust-sticking rollers 10 to move close to the skewed position of the dust-free cloth, and the two rubber dust-sticking rollers 10 can be controlled to rotate together, so that the fourth slide groove 25 opened on the outer wall of the two rubber dust-sticking rollers 10 rotates to the bottom, and then the telescopic ends of the two first electric telescopic rods 29 are controlled to extend downward together, driving the two arc plates 27 to extend downward from the inside of the corresponding storage groove 26 until the arc plate 27 contacts the dust-free cloth, and then the corresponding fourth slider 28 is controlled to move and adjust inside the fourth slide groove 25, and the arc plate 27 is driven to move synchronously, so that the dust-free cloth with a deviation in position can be pushed at the top of the conveyor belt 2 with the help of the movement of the arc plate 27, ensuring that the dust-free cloth is located at 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 as mentioned above 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 on 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 dust-sticking 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. After the dust or other impurities at the bottom of the dust-free cloth are removed, the two moving seats 9 and other components are located at one end of the dust-free cloth, and the telescopic ends of the multiple second electric telescopic rods 34 are controlled 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 dust-sticking rollers 10 are in friction contact with the top of the dust-free cloth, and the two rubber dust-sticking rollers 10 can be used to adhere and remove the dust or other impurities attached to the top of the dust-free cloth, so as to achieve the effect of comprehensively cleaning the surface of the dust-free cloth, and reduce the problem of 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 grooves 3 toward the front side close to 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 extraction 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 grooves 3 enables the laser cutting head 14 to cut a whole piece of dust-free cloth into multiple parts of the same volume. The suction generated by the two smoke extraction hoods 12 can absorb the smoke generated by the cutting to prevent 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 materials at the four edge positions of the original whole piece of dust-free cloth. The two rubber dust-sticking rollers 10 can be controlled to rotate to ensure that the fourth slide groove 25 is located at the bottom, and the waste materials of the dust-free cloth close to the front of the device body 1 are lifted up. Then, the telescopic ends of the multiple first electric telescopic rods 29 are controlled to extend together, and the multiple arc plates 27 are pushed downward from the corresponding storage grooves 26, so that the multiple extended arc plates 27 can abut against the edge waste materials of the dust-free cloth after being lifted up and folded. Then, the two moving seats 9 are controlled to move toward the direction close to the back of the device body 1. With the help of the multiple arc plates 27, the edge waste materials of the dust-free cloth can be preferentially pushed off from the top of the conveyor belt 2, so as to achieve the effect of automatically removing the waste materials.

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

[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, before controlling the conveyor belt 2 to rotate to convey the cut dust-free cloth, the two moving seats 9 can be controlled to drive the two rubber dust-sticking rollers 10 to move to the top of the two dust-free cloths with the sticking phenomenon, and 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, and the two rubber dust-sticking rollers 10 can also be driven to move in the direction of approaching to the specified position. At this time, the two rubber dust-sticking rollers 10 are still on the two The two rubber dust-free cloths are placed above the two adhered dust-free cloths, and the two movable plates 20 are used to drive the two rubber dust-free rollers 10 to move downward together, so that the two rubber dust-free rollers 10 can press and fix the two adhered dust-free cloths respectively, and then the two first double-headed screws 24 can be controlled to reverse, driving the two rubber dust-free rollers 10 to move in directions 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, without having 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 fails during use and cannot automatically convey and discharge the cut dust-free cloths downward, 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 then 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 direction 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 cut dust-free cloths on the top of the conveyor belt 2 are pushed down to the bottom of the device body 1, thereby automatically unloading the cut dust-free cloths instead of the conveyor belt 2, avoiding the problem that the 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 against the outer walls of the two rubber sticky rollers 10, and controlling the external preset liquid spraying device to start, and spraying the detergent on the surfaces of the two rubber sticky rollers 10 through the multiple spray holes 35, so that the surfaces of the two rubber sticky rollers 10 can be automatically cleaned. While the detergent is sprayed on 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 moving 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 detergent can be fully sprayed on the surfaces of the two rubber sticky rollers 10, and the surfaces of the two rubber sticky rollers 10 can be scraped, so as to achieve the effect of automatically cleaning and removing 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.
