Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to a laser cutting device for processing optical film materials. Background Art

[0002] Optical film is a type of thin film material with special optical properties. It can precisely control light through reflection, transmission, absorption, polarization, phase adjustment and other effects on light. It is widely used in display, optical instruments, new energy, security and other fields. The essence of optical film is "light control tool". Through the design of film structure and materials, it can precisely control the transmission, reflection, polarization and other characteristics of light. In the processing of optical film, laser cutting is an advanced processing method with high precision and low damage. It is especially suitable for optical film with strict requirements on "edge quality, dimensional accuracy and no mechanical stress". Laser cutting focuses a high-energy-density laser beam on the surface of the film material, and uses the thermal effect or photochemical effect of the laser to instantly remove the film material in the irradiated area. At the same time, the motion trajectory of the laser beam is controlled by the CNC system to achieve precise contour cutting. When optical film materials are continuously laser cut by laser cutting equipment, the subsequent optical film materials are guided to ensure that the bottom of the film cutting position is hollow so that the film materials can be cut smoothly. As a result, during the continuous cutting and transportation of the film materials, the cutting end face is prone to enter the hollow position, causing material jamming and affecting the continuous cutting of the plate. Summary of the Invention

[0003] To achieve the above objectives, the present invention is implemented through the following technical solutions: A laser cutting device for processing optical film materials, comprising: A frame, a support frame is fixedly installed on the top of the frame, and a discharge guide plate is fixedly installed on the outer side of the support frame; A cooling mechanism is installed inside the support frame and is used to press and cool the optical film material at the cutting position; A conveying mechanism, the conveying mechanism is installed on the top of the frame, and the conveying mechanism is located on a side of the support frame away from the discharge guide plate; The top of the outer side of the support frame is fixedly installed with a first motor, and the inner wall of the support frame is rotatably installed with a screw rod, one end of the screw rod is fixedly connected to the output end of the first motor, and the outer side of the screw rod is threadedly connected to a slider, and the inner wall of the support frame is fixedly installed with side clamps, and the side clamps are symmetrically installed along the center position of the axis of the support frame, the screw rod is located between the side clamps, and the side clamps are opposite surfaces that slide with the two sides of the slider, and a laser cutting head is fixedly installed on the bottom of the slider, and a support plate is fixedly installed on the inner wall of the support frame, and a groove is provided at the center position of the top of the support plate, and the groove of the support plate is fixed An inclined guide bar is fixedly installed, and the inclined guide bar cooperates with the bar groove of the support plate. During the cutting process, the inclined guide bar is tilted so that the bottom of the film cutting position does not touch the object, ensuring that during laser cutting, after the laser energy cuts the film material, the excess energy will not be transmitted to the surface of the component in contact with the film material. At the same time, in the subsequent process of transmitting the film material, the cut end face of the film material is guided by the inclined guide bar, so that the film material is smoothly introduced into the bottom of the cooling mechanism, avoiding the occurrence of material jamming during the continuous cutting and transportation of the film material due to the hollow bottom of the film cutting position. The end of the inclined guide bar away from the discharge guide plate is tilted downward.

[0004] Preferably, the strip groove of the support plate is located directly below the laser cutting head, and an inclined slide groove is provided on the side of the top of the support plate away from the discharge guide plate, and the inclined slide groove is inclined from top to bottom toward the discharge guide plate, and an inclined slide plate is slidably installed at the inclined slide groove of the support plate, and a rotating roller is rotatably installed on the top of the inclined slide plate, and a second motor is fixedly installed on the outer side of the support frame, and a transmission roller is rotatably installed on the inner wall of the support frame, one end of the transmission roller is fixedly connected to the output end of the second motor, and the transmission roller is located between the inclined slide plate and the strip groove of the support plate, and the inclined slide plate can slide in the inclined slide groove of the support plate through the cooperation between the inclined slide groove of the support plate and the inclined slide plate. During the transmission of the membrane material, when the roller contacts the membrane material, the contact pressure between the roller and the membrane material is transmitted to the bottom pad through the inclined slide, and the elastic deformation of the elastic material of the bottom pad when under pressure is used to buffer the pressure. At the same time, the inclined sliding slide can ensure the taut state of the membrane material when the membrane material is lifted upward. At the same time, the position of the roller is away from the transmission roller when the lifting height is increased, avoiding being close to the transmission roller position, resulting in excessive curling of the membrane material when the lifting height is high, causing damage to the membrane material. The bottom of the support plate is fixedly installed with a bottom plate, and the bottom pad is fixedly installed between the top of the bottom plate and the bottom of the inclined slide, and the elastic material of the bottom pad is fixedly installed.

[0005] Preferably, the cooling mechanism includes a side sliding frame, which is symmetrically mounted on both sides of the inner wall of the support frame along the center position of the axis of the support frame, and connecting plates are slidably mounted on opposite surfaces of the side sliding frame, and an inner pad is fixedly mounted between the top of the connecting plate and the inner wall of the side sliding frame. The inner pad is made of elastic rubber material, and the connecting plate is restricted by the side sliding frame so that the height of the cold water tank is always at the same height. After each cutting is completed, the cold water tank on one side is lifted up by the membrane material that needs to be cut later, so that the cold water tank on the other side is still at the same height, ensuring that the other side The gap width at the bottom of the side cold water trough avoids the situation where there is no gap at the bottom of the cold water trough on the other side when guiding the membrane material that needs to be cut later, making it difficult to guide the membrane material to its bottom, resulting in the membrane material being stuck. A cold water trough is fixedly installed between the connecting plates. There are two cold water troughs and they are symmetrically installed along the center position of the axis of the connecting plate. There is a gap between the cold water troughs, and the gap of the cold water trough corresponds to the groove of the support plate. The cold water trough is located between the support plate and the laser cutting head. The bottom of the cold water trough is flat, and a rubber pad is fixedly installed at the bottom of the cold water trough.

[0006] Preferably, the conveying mechanism includes a fixed frame, the inner wall of the fixed frame is rotatably installed with a conveying roller, the conveying roller is symmetrically installed along the center position of the axis of the fixed frame, and a third motor is fixedly installed on the outer side of the fixed frame, the output end of the third motor is fixedly connected to one end of the conveying roller, and a transmission belt is installed for transmission between the conveying rollers, and a bottom support plate is fixedly installed on the inner wall of the fixed frame, which cooperates with the transmission belt and supports the transmission belt by the bottom support plate so that the top of the transmission belt is in a plane, increasing the contact area with the film material, increasing the friction force, and smoothly conveying the film material. At the same time, the support of the bottom support plate avoids the film material from curling too much during the conveying process, prevents the film material from curling too much during transportation, and prevents creases from occurring, which affects the use of the film material. The bottom support plate is located between the conveying rollers and on the inner side of the transmission belt, and the top of the bottom support plate is tightly fitted with the inner wall of the transmission belt.

[0007] Preferably, side frame plates are fixedly installed on both sides of the top of the fixed frame, and fixed plates are slidably installed on the opposite surfaces of the side frame plates, and side pads are fixedly installed between the top of the fixed plate and the inner wall of the side frame plates. The side pads are made of elastic material, and a pressing roller is rotatably installed between the fixed plates. When the film material is introduced, the film material lifts the pressing belt, so that the side pads are deformed under the lifting pressure to generate elastic force, thereby increasing the pressure of the pressing belt on the film material, and increasing the contact pressure of the two sides of the film material with the pressing belt and the transmission belt, thereby ensuring the friction between the film material and avoiding slipping of the film material during transmission due to the smooth surface of the film material and low friction, thereby affecting the guiding accuracy. The pressing rollers are evenly installed between the fixed plates and are located above the bottom support plate, and a pressing belt is installed for transmission between the pressing rollers.

[0008] The present invention provides a laser cutting device for processing optical film materials. It has the following beneficial effects: 1. The laser cutting equipment for processing optical film materials cooperates with the grooves of the support plate through the inclined guide bars. During the cutting process, the inclined guide bars are used to prevent the bottom of the film cutting position from contacting the object, ensuring that after the laser energy cuts the film, the excess energy will not be transferred to the surface of the parts in contact with the film. At the same time, in the subsequent process of transmitting the film material, the cut end face of the film material is guided by the inclined guide bars, so that the film material is smoothly introduced into the bottom of the cooling mechanism, avoiding the occurrence of material jamming during the continuous cutting and transportation of the film material due to the hollow bottom of the film cutting position.

[0009] 2. The laser cutting equipment for processing optical film materials cooperates with the inclined slide plate through the inclined groove of the support plate, so that the inclined slide plate can slide in the inclined groove of the support plate. During the transmission of the film material, the contact pressure between the roller and the film material is transmitted to the bottom plate through the inclined slide plate. The elastic deformation of the elastic material of the bottom plate when under pressure is used to buffer the pressure. At the same time, the inclined sliding slide plate can ensure the taut state of the film material when the film material is lifted upward. At the same time, the position of the roller is away from the transmission roller when the lifting height is increased, so as to avoid being too close to the transmission roller, which causes the film material to curl too much when the lifting height is high, resulting in damage to the film material.

[0010] 3. The laser cutting equipment for processing optical film materials limits the connecting plate through a side sliding frame so that the height of the cold water trough is always at the same height. After each cutting is completed, the cold water trough on one side is lifted up with the film material that needs to be cut later, so that the cold water trough on the other side remains at the same height, ensuring the gap width at the bottom of the cold water trough on the other side, avoiding the situation where there is no gap at the bottom of the cold water trough on the other side when guiding the film material that needs to be cut later, and the film material is difficult to guide into its bottom, resulting in film material jamming.

[0011] 4. The laser cutting equipment for processing optical film materials cooperates with the transmission belt through the bottom support plate. The bottom support plate supports the transmission belt so that the top of the transmission belt is flat, increasing the contact area with the film material and improving the friction. While smoothly conveying the film material, the support of the bottom support plate prevents the film material from curling too much during the transmission process, preventing the film material from curling too much during transportation and causing creases, which affects the use of the film material.

[0012] 5. When the optical film material is introduced into the laser cutting equipment, the film material pushes up the pressing belt, causing the side pads to deform under the pushing pressure and generate elastic force, thereby increasing the pressure of the pressing belt on the film material, and increasing the contact pressure between the two sides of the film material and the pressing belt and the transmission belt, thereby ensuring the friction between the film material and the film material, and avoiding the film material from slipping during transmission due to the smooth surface and low friction of the film material, thereby affecting the guiding accuracy.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: A laser cutting device for processing optical film materials, comprising: The frame 1 has a support frame 4 fixedly mounted on the top of the frame 1, and a discharge guide plate 5 fixedly mounted on the outside of the support frame 4; The cooling mechanism 2 is installed inside the support frame 4 and is used to press and cool the optical film material at the cutting position; The conveying mechanism 3 is installed on the top of the frame 1, and the conveying mechanism 3 is located on the side of the support frame 4 away from the discharge guide plate 5; A first motor 7 is fixedly installed on the top of the outer side of the support frame 4, and a screw rod 8 is rotatably installed on the inner wall of the support frame 4. One end of the screw rod 8 is fixedly connected to the output end of the first motor 7, and the outer side of the screw rod 8 is threadedly connected to a slider 9. A side splint 10 is fixedly installed on the inner wall of the support frame 4. The side splint 10 is symmetrically installed along the center position of the axis of the support frame 4. The screw rod 8 is located between the side splints 10. The side splints 10 are opposite surfaces that slide with the two sides of the slider 9. A laser cutting head 6 is fixedly installed on the bottom of the slider 9. A support plate 11 is fixedly installed on the inner wall of the support frame 4. When the film material is guided into the bottom of the laser cutting head 6 through the conveying mechanism 3, the film material passes through the top of the rotating roller 17, and then enters between the transmission roller 13 and the support plate 11, and the transmission roller is driven by the second motor 12 13 rotates, so that the transmission roller 13 assists the conveying mechanism 3, drives the film material into the bottom of the cooling mechanism 2, and makes the film material move at the bottom of the cooling mechanism 2, so that during the movement of the film material, the cutting position of the film material corresponds to the groove of the support plate 11. After the cutting is completed, when the subsequent film material to be cut is driven to move, the inclined guide bar 18 cooperates with the transmission roller 13, and the inclined guide bar 18 is used to guide the cut end face of the film material during the subsequent movement of the film material, so that the film material can smoothly push the film material that has been cut to be discharged from the bottom of the cooling mechanism 2, and the subsequent film material can smoothly enter the bottom of the cooling mechanism 2. A groove is provided at the center position of the top of the support plate 11, and an inclined guide bar 18 is fixedly installed at the groove of the support plate 11, and the inclined guide bar 18 is inclined downward at the end away from the discharge guide plate 5.

[0017] The strip groove of the support plate 11 is located just below the laser cutting head 6, and an inclined slot is provided on the top of the support plate 11 away from the side of the discharge guide plate 5, and the inclined slot is inclined from top to bottom toward the discharge guide plate 5. An inclined slide 16 is slidably installed at the inclined slot of the support plate 11, and a roller 17 is rotatably installed on the top of the inclined slide 16. A second motor 12 is fixedly installed on the outside of the support frame 4, and a transmission roller 13 is rotatably installed on the inner wall of the support frame 4. During the transmission of the film material, the bottom pad on the top of the bottom plate 14 is passed through. The plate 15 supports the inclined slide 16, so that the inclined slide 16 pushes the film material through the roller 17, and cooperates with the transmission roller 13 and the support plate 11 to clamp the film material, so that the film material is in a taut state. One end of the transmission roller 13 is fixedly connected to the output end of the second motor 12. The transmission roller 13 is located between the inclined slide 16 and the groove of the support plate 11. The bottom of the support plate 11 is fixedly installed with a bottom plate 14, and a bottom pad 15 is fixedly installed between the top of the bottom plate 14 and the bottom of the inclined slide 16. The bottom pad 15 is made of elastic material.

[0018] The second embodiment, based on the first embodiment, see Figures 7 and 8 As shown, the cooling mechanism 2 includes a side sliding frame 21, which is symmetrically installed on both sides of the inner wall of the support frame 4 along the center position of the axis of the support frame 4, and the opposite surfaces of the side sliding frame 21 are slidably installed with connecting plates 23, and an inner pad 24 is fixedly installed between the top of the connecting plate 23 and the inner wall of the side sliding frame 21. The inner pad 24 is made of elastic rubber material, and a cold water trough 22 is fixedly installed between the connecting plates 23. In the cooling mechanism 2, when the membrane material is initially introduced, the worker lifts the cold water trough 22, so that the cold water trough 22 drives the connecting plates 23 on both sides to slide upward inside the side sliding frame 21, compressing the inner pad 24, so that the inner pad 24 is deformed under pressure to generate elastic force, and makes the bottom of the cold water trough 22 contact the membrane At the top of the material, there are two cold water troughs 22 and they are symmetrically installed along the center position of the axis of the connecting plate 23. There is a gap between the cold water troughs 22, and the gap of the cold water troughs 22 corresponds to the groove of the support plate 11. The cold water troughs 22 are located between the support plate 11 and the laser cutting head 6. By injecting cooling liquid into the cold water troughs 22, the cold water troughs 22 contact the film material on both sides of the film cutting position, and absorb heat on both sides of the film cutting position during cutting, avoiding a large amount of heat from being transferred to the film material on both sides of the cutting position during cutting, resulting in excessive temperature rise of the film material near the film cutting position. The bottom of the cold water trough 22 is flat, and a rubber pad 25 is fixedly installed on the bottom of the cold water trough 22.

[0019] The third embodiment, based on the first and second embodiments, see Figures 9 and 10As shown, the conveying mechanism 3 includes a fixed frame 301, and a conveying roller 310 is rotatably installed on the inner wall of the fixed frame 301. The conveying roller 310 is symmetrically installed along the center position of the axis of the fixed frame 301. A third motor 302 is fixedly installed on the outer side of the fixed frame 301. The output end of the third motor 302 is fixedly connected to one end of the conveying roller 310. A transmission belt 304 is installed between the conveying rollers 310. The worker guides the film material between the pressing belt 305 and the transmission belt 304. The contact pressure between the film material and the pressing belt 305 is transmitted through the pressing roller. The elastic force is transmitted to the side pad 308 by 307 and the fixed plate 309, so that the side pad 308 deforms elastically under pressure to generate elastic force. The elastic force passes through the fixed plate 309 and the pressing roller 307, so that the pressing belt 305 squeezes the film material toward the transmission belt 304, thereby increasing the fitting pressure between the film material and the transmission belt 304. The inner wall of the fixed frame 301 is fixedly installed with a bottom support plate 306, which is located between the conveying rollers 310 and on the inner side of the transmission belt 304. The top of the bottom support plate 306 is in close contact with the inner wall of the transmission belt 304.

[0020] Side frame plates 303 are fixedly installed on both sides of the top of the fixed frame 301, and fixed plates 309 are slidably installed on the opposite surfaces of the side frame plates 303. Side pads 308 are fixedly installed between the top of the fixed plates 309 and the inner wall of the side frame plates 303. The side pads 308 are made of elastic material and are supported inside the transmission belt 304 by the bottom support plate 306 to prevent the transmission belt 304 from deforming under pressure, so that the film material is flat and guided to the position of the laser cutting head 6 through the conveying mechanism 3. A pressing roller 307 is rotatably installed between the fixed plates 309. The pressing rollers 307 are evenly installed between the fixed plates 309 and are located above the bottom support plate 306. A pressing belt 305 is installed for transmission between the pressing rollers 307.

[0021] During use, the optical film material to be cut is introduced into the equipment through one end of the conveying mechanism 3, and the film material to be cut is driven by the conveying mechanism 3 to move to the bottom of the laser cutting head 6. Then the film material passes through the top of the rotating roller 17 and finally passes through the bottom of the transmission roller 13. The transmission roller 13 is driven to rotate by the second motor 12, so that the transmission roller 13 cooperates with the conveying mechanism 3 to drive the film material into the bottom of the cooling mechanism 2 and make the film material reach the cutting position. The screw rod 8 is driven to rotate by the first motor 7, and the threaded connection between the screw rod 8 and the slider 9 is utilized to make the slider 9 drive the laser cutting head 6 along the axial direction of the screw rod 8 under the restriction of the side clamp 10, and the film material at the bottom is laser cut. The cut film material is discharged from the position of the discharge guide plate 5.

[0022] When the film is guided by the conveying mechanism 3 and introduced into the bottom of the laser cutting head 6, the film passes through the top of the rotating roller 17 and then enters between the transmission roller 13 and the support plate 11. The transmission roller 13 is driven to rotate by the second motor 12, so that the transmission roller 13 assists the conveying mechanism 3, drives the film into the bottom of the cooling mechanism 2, and makes the film move at the bottom of the cooling mechanism 2. During the movement of the film, the cutting position of the film corresponds to the groove of the support plate 11. After the cutting is completed, the film to be cut subsequently is driven to move At the same time, the inclined guide bar 18 cooperates with the transmission roller 13, and the inclined guide bar 18 is used to guide the cut end face of the film material during the subsequent movement of the film material, so that the film material can smoothly push the bottom of the cooling mechanism 2 to complete the cutting of the film material and enable the subsequent film material to smoothly enter the bottom of the cooling mechanism 2. At the same time, during the transmission of the film material, the bottom pad 15 on the top of the bottom plate 14 supports the inclined slide 16, so that the inclined slide 16 pushes the film material through the roller 17, and cooperates with the transmission roller 13 and the support plate 11 to clamp the film material, so that the film material is in a taut state.

[0023] In the conveying mechanism 3, the worker guides the film material between the pressing belt 305 and the transmission belt 304. The contact pressure between the film material and the pressing belt 305 is transmitted to the side pad 308 through the pressing roller 307 and the fixed plate 309, so that the side pad 308 elastically deforms itself under pressure to generate elastic force. The elastic force passes through the fixed plate 309 and the pressing roller 307, so that the pressing belt 305 squeezes the film material toward the transmission belt 304, thereby increasing the fitting pressure between the film material and the transmission belt 304. At the same time, the bottom support plate 306 supports the inside of the transmission belt 304 to prevent the transmission belt 304 from deforming under pressure, so that the film material is smoothly guided through the conveying mechanism 3 to the position of the laser cutting head 6.

[0024] In the cooling mechanism 2, when the membrane material is initially introduced, the worker lifts the cold water trough 22, so that the cold water trough 22 drives the connecting plates 23 on both sides to slide upward inside the side sliding frame 21, compressing the inner pad 24, causing the inner pad 24 to deform under pressure to generate elastic force, and making the bottom of the cold water trough 22 contact the top of the membrane material. By injecting cooling liquid into the cold water trough 22, the cold water trough 22 contacts the membrane material on both sides of the membrane cutting position, and absorbs heat on both sides of the membrane cutting position during cutting, avoiding a large amount of heat from being transferred to the membrane material on both sides of the cutting position during cutting, resulting in excessive temperature rise of the membrane material near the membrane cutting position.
