Description

Technical Field

[0001] This invention relates to the field of screen processing technology, and more specifically to a laser cutting device for screen processing. Background Technology

[0002] In screen manufacturing, screen cutting is a crucial process. Laser cutting uses an invisible beam of light instead of a traditional mechanical blade. The screen substrate is placed on a laser cutting plate and positioned. The laser cutting trajectory is input into a controller, which then activates the laser cutting head to cut the glass substrate. This method avoids unnecessary damage to the screen substrate during cutting, resulting in a good cutting effect, a clean cut, high precision, and fast cutting speed. It is gradually improving upon or replacing traditional metal cutting equipment.

[0003] Application CN202210576383.1 relates to the field of mobile phone screen cutting technology and discloses a mobile phone screen cutting and collection device. The device includes a cutting platform and a laser. The laser is disposed on the cutting platform and is used to cut the screen. Two clamping plates are disposed on the cutting platform to clamp the screen. A material collection component is detachably connected to the clamping plates and is located below the screen. The material collection component is used to collect the scrap generated after screen cutting. This application reduces the accumulation of scrap, thereby facilitating screen fixation and minimizing the impact on screen cutting efficiency.

[0004] However, this application uses a clamp to fix the screen, which is difficult to achieve effective fixation if the screen is thin.

[0010] Furthermore, a suction head is fixedly mounted on the suction cup; and a through hole corresponding to the suction head is provided on the support plate.

[0011] Furthermore, the suction assembly includes: a fixed sleeve; an air hole formed on the fixed sleeve; a piston plate slidably mounted on the fixed sleeve; a top head; and a stop block fixedly mounted on the fixed sleeve.

[0012] Furthermore, a piston plate two is fixedly installed on the top head; a rack one is fixedly installed on the piston plate two; a gear meshes on the rack one; a rack two meshes on the gear; the rack two is fixedly installed on the piston plate one; and the top head is fixedly connected to the suction cup.

[0013] Furthermore, the fixed sleeve is fixedly installed on the machine base; the gear is rotatably installed on the fixed sleeve.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a laser cutting device for screen processing. A cylinder drives an adjusting plate to move. As the adjusting plate moves towards the screen, a pusher slides inside a cylinder, pushing gas from inside the cylinder through an air pipe into a sliding frame. This pushes a connecting plate to slide within the sliding frame, thereby moving a fixing plate and a pressure head towards the screen. The pressure head then pushes the screen towards a baffle, allowing the baffle to contact the screen for alignment and fixation. When the fixing plate pushes the screen to the baffle, it continues to move. At this point, the fixing plate is influenced by the inclined guide surface on the pressure head, causing it to move upwards. This causes the fixing plate to slide the connecting plate within a groove, moving the pressure head above the screen. The pressure head moves above the screen to prevent damage. As the connecting plate slides within the groove, it causes a spring to deform, causing the connecting plate, fixing plate, and pressure head to move upwards. The tension from the deformed spring and pressure head then presses the screen down from above, ensuring stability after positioning. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 12 As shown, the present invention discloses a laser cutting device for screen processing, comprising: a machine base 1, a loading rack 2 fixedly installed on the machine base 1; a fixing frame 31 installed on the loading rack 2; a cutting assembly 4 installed on the machine base 1; a loading platform 5 and a unloading platform 6 fixedly installed on the machine base 1; the fixing frame 31 is slidably connected to the loading rack 2, and after the fixing frame 31 fixes the screen, the screen is adjusted in position by sliding on the loading rack 2, and then cut by the cutting assembly 4. The loading platform 5 and the unloading platform 6 can hold trays for carrying the screen, and the screen is loaded and unloaded by a loading and unloading robot.

[0024] An electric telescopic rod can be installed on the feeding rack 2 to slide on the feeding rack 2 in conjunction with the fixing part 3. The cutting component 4 is composed of a three-axis moving module and a laser cutting head. The three-axis moving module drives the laser cutting head to move, so that the position of the laser cutting head can be adjusted to facilitate cutting the screen.

[0025] It should be noted that loading the screen with a robotic arm can cause a deviation in the position of the screen on the fixing part 3. The screen needs to be repositioned and fixed before cutting.

[0026] The fixing component 3 includes: a fixing frame 31, which slides on the loading rack 2 to move the screen; a baffle 32 and a limiting plate 33 fixedly installed on the fixing frame 31, the baffle 32 and the limiting plate 33 being set at an L-shaped right angle; a fixing component 34 for fixing the screen; a base plate 35 and a support plate 37 installed on the fixing frame 31; a suction cup 36 disposed between the base plate 35 and the support plate 37; and a suction-fixing component 38. The screen is placed on the support plate 37, and the baffle 32 and the limiting plate 33 limit the screen position to the lower left corner (or lower right corner) of the support plate 37, fixing it at a unique coordinate point to ensure that the cutting starting point position is consistent when each screen is placed. Then, the suction cup 36 and the suction-fixing component 38 fix the screen, and finally, the fixing component 34 performs secondary fixation to ensure that the screen is in contact with the baffle 32 and the limiting plate 33, thus ensuring the positioning of the screen.

[0027] In detail, a rotating shaft 351 is fixedly installed at one end of the base plate 35 and the support plate 37; the base plate 35 and the support plate 37 are rotatably connected to the fixing frame 31 through the rotating shaft 351; a hinge rod 353 is rotatably installed on the base plate 35; the hinge rod 353 is rotatably connected to the support plate 37. When the base plate 35 rotates through the rotating shaft 351, the support plate 37 is simultaneously rotated through the hinge rod 353. In the default state, the base plate 35 and the support plate 37 tilt when rotating through the rotating shaft 351. When the screen is loaded by the robotic arm, it slides on the support plate 37 and comes into contact with the limiting plate 33. Then, the upward movement of the suction cup 36 causes the support plate 37 and the base plate 35 to rotate through the rotating shaft 351 and become horizontal with the machine base 1, ensuring the stability of the screen position. Then, the fixing component 34 moves towards the screen and pushes the screen to contact the baffle 32. Then, the screen is fixed from above. At the same time, the suction cup 36 uses negative pressure to fix the screen a second time, ensuring the fixing effect of the screen.

[0028] It should be added that the fixing component 34 includes: a cylinder 341; an adjusting plate 342 fixedly installed at the output end of the cylinder 341; a push plate 343 fixedly installed on the adjusting plate 342; an air cylinder 344 sleeved on the push plate 343; an air pipe 345 connected to the air cylinder 344; a sliding frame 346 fixedly installed on the air pipe 345; a connecting plate 347 slidably installed on the sliding frame 346; and a fixing plate 348 fixedly installed on the connecting plate 347. A pressure head 349 is fixedly installed on the fixed plate 348; an air cylinder 344 is fixedly installed on the fixed frame 31; a cylinder 341 is fixedly installed on the fixed frame 31; a limit rod 3410 is fixedly installed on the fixed frame 31; an adjusting plate 342 is slidably connected to the limit rod 3410. When the adjusting plate 342 moves, it slides on the limit rod 3410, and the limit rod 3410 limits the adjusting plate 342 to ensure the stability of the adjusting plate 342 when it moves.

[0029] When fixing the screen, the cylinder 341 is activated to move the adjusting plate 342. When the adjusting plate 342 moves toward the screen, the push plate 343 slides inside the air cylinder 344, pushing the gas inside the air cylinder 344 through the air pipe 345 into the sliding frame 346, pushing the connecting plate 347 to slide inside the sliding frame 346, thereby driving the fixing plate 348 and the pressure head 349 to move toward the screen. The pressure head 349 pushes the screen toward the baffle 32, so that the baffle 32 contacts the screen to align and fix the screen.

[0030] It should be noted that the adjusting plate 342 has a sliding groove 3421; a sliding plate 3472 is slidably installed in the sliding groove 3421; a spring 3471 is fixedly installed on the sliding plate 3472; the spring 3471 is fixedly installed on the connecting plate 347; when the fixed plate 348 pushes the screen to the baffle 32, the fixed plate 348 continues to move. At this time, the fixed plate 348 is affected by the inclined guide surface on the pressure head 349, which drives the fixed plate 348 to move upward, so that the fixed plate 348... The connecting plate 347 slides within the slide groove 3421, causing the pressure head 349 to move above the screen. At this time, the pressure head 349 moves on the screen to avoid damaging it. When the connecting plate 347 slides within the slide groove 3421, it causes the spring 3471 to deform, causing the connecting plate 347, the fixing plate 348, and the pressure head 349 to move upward. Through the tension of the pressure head 349 and the spring 3471 after deformation, the pressure head 349 is driven to press down and fix the screen from above, ensuring the stability of the screen after positioning.

[0031] When the position of the pressure head 349 needs to be adjusted according to the screen thickness, the adjustment is achieved by sliding the slide plate 3472 inside the slide groove 3421. After the adjustment is completed, the position of the slide plate 3472 is fixed by bolts, thereby realizing the adjustment of the position of the pressure head 349.

[0032] It should also be noted that a limiting sleeve 352 is fixedly installed on the fixing frame 31; a slot 3511 is provided on the rotating shaft 351; a connecting hole 3521 is provided on the limiting sleeve 352; a clamping head 3522 is fixedly installed on the connecting hole 3521; the clamping head 3522 is slidably connected to the slot 3511. When the rotating shaft 351 rotates, the rotating shaft 351 rotates in the connecting hole 3521, and the clamping head 3522 slides inside the slot 3511. The mutual limiting of the slot 3511 and the clamping head 3522 prevents the base plate 35 and the support plate 37 from rotating excessively, which would affect the use.

[0033] It should be added that a suction head 361 is fixedly installed on the suction cup 36; a through hole corresponding to the suction head 361 is opened on the support plate 37. The suction cup 36 slides between the base plate 35 and the support plate 37. When the suction head 361 on the suction cup 36 slides out of the through hole, the base plate 35 and the support plate 37 tilt due to the rotation of the pivot 351. The suction cup 36 moves up and contacts the support plate 37. The continuous movement of the suction cup 36 drives the support plate 37 to rotate. After the support plate 37 is horizontal, the suction cup 36 continues to move, allowing the suction head 361 to enter the through hole and fix the screen on the support plate 37.

[0034] The suction assembly 38 includes: a fixed sleeve 381, which is fixedly installed on the machine base 1; an air hole 3811 formed on the fixed sleeve 381; a piston plate 3812 and a top head 3813 slidably installed on the fixed sleeve 381; a stop block 3814 fixedly installed on the fixed sleeve 381; a piston plate 38131 fixedly installed on the top head 3813; a rack 38132 fixedly installed on the piston plate 38131; a gear 38133 meshing on the rack 38132, which is rotatably installed on the fixed sleeve 381; a rack 38134 meshing on the gear 38133; a rack 38134 fixedly installed on the piston plate 3812; and the top head 3813 is fixedly connected to the suction cup 36.

[0035] When air is drawn through vent 3811, piston plate 3812 moves downward. Piston plate 3812 drives gear 38133 to rotate via rack 38132. Gear 38133 drives rack 38134 to rotate, which in turn drives piston plate 38131 to move upward. Piston plate 38131 drives top head 3813 to move. Top head 3813 drives suction cup 36 to move upward. When piston plate 3812 abuts against stop block 3814, piston plate 38131 stops moving top head 3813 and suction cup 36.

[0036] It should be noted that a connecting pipe 382 is fixedly installed on the fixed sleeve 381, and a fixed frame 383 is connected to the connecting pipe 382; in this application, air is drawn out through the air hole 3811 by a vacuum pump. When the piston plate 3812 stops moving, air continues to be drawn out in the air hole 3811, and the gas in the fixed frame 383 is drawn out through the connecting pipe 382.

[0037] The fixed frame 383 is connected to the suction cup 36. When the fixed frame 383 is evacuated, the screen is fixed by negative pressure through the suction cup 36 and the suction head 361. It should be noted that when the screen is cut, the debris and residue generated by cutting will fall onto the base plate 35 and the support plate 37. When the base plate 35 and the support plate 37 rotate, the waste on the surface is discharged outward to avoid affecting the processing. However, the debris on the support plate 37 will fall into the suction head 361, affecting the use of the vacuum pump.

[0038] A fixing block 3831 is fixedly installed on the fixing frame 383; a folding plate 3832 is fixedly installed on the fixing block 3831; a filter screen 3833 is fixedly installed on the fixing block 3831; the fixing frame 383 is provided with an inclined surface 3834; the fixing frame 383 is connected to the suction cup 36 through a flexible tube; the connecting pipe 382 is fixedly connected to the fixing block 3831; the filter screen 3833 is fixedly installed on the fixing frame 383, and if it breaks when air is drawn through the connecting pipe 382... When debris enters the fixed frame 383, it can be filtered by the filter screen 3833 to avoid affecting its use. The inclined surface 3834 inside the fixed frame 383 can prevent dead spots that could cause debris to accumulate. When the base plate 35 and the support plate 37 rotate, the fixed frame 383 rotates synchronously. At this time, the debris remaining in the fixed frame 383 enters between the folding plate 3832 and the fixed frame 383, preventing debris from flying. However, dead spots may occur at the connection between the folding plate 3832 and the fixed block 3831.

[0039] It should be added that one end of the connecting pipe 382 has a second air hole 3821; an energy storage plate 3822 is slidably mounted on the connecting pipe 382; a second spring 3823 is fixedly mounted on the energy storage plate 3822; one end of the connecting pipe 382 has a third air hole 3824; the other end of the second spring 3823 is fixedly mounted on the connecting pipe 382. To prevent debris from accumulating at the dead point of the folding plate 3832 and affecting its use, when the vacuum pump is pumping air, it drives the energy storage plate 3822 to move, storing air. When the energy plate 3822 moves, it causes the second spring 3823 to deform. When the vacuum pump stops, the second spring 3823 resets, causing the energy plate 3822 to reset in the connecting pipe 382, ​​so that the gas at the end of the connecting pipe 382 is discharged through the third air hole 3824. The third air hole 3824 is located at the dead point on the folding plate 3832. The dead point is cleaned by the discharge of gas to avoid the accumulation of debris. The vacuum pump draws air into the fixed frame 383 through the second air hole 3821, which drives the suction cup 36 to fix the screen.
