[0002] LCD screen, or liquid crystal display, is a display technology belonging to flat panel displays. During the production and cutting process of LCD screens, in order to better control the deformation and stress distribution during the cutting process, large screens are usually cut into small strips with relatively narrow widths first, and then the small strips are cut into the final required small screens. This can effectively reduce the impact of internal stress generated by cutting on screen performance and improve cutting accuracy and product quality.

[0003] Chinese patent announcement number CN219275962U discloses an LCD liquid crystal screen module cutting device, including a workbench, a support frame and a descending component. The descending component includes a moving frame, a first motor, a first screw rod, a first guide rail, a mounting frame, a cutting machine, a positioning component and a moving component.

The moving component can realize the horizontal reciprocating movement of the cutting machine.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 and Figure 2As shown, a cutting device for LCD screen production includes an operating table 1, a fixing mechanism 4 is slidably connected to the middle of the upper end of the operating table 1, a cutting mechanism 3 is fixedly connected to the rear side of the middle of the upper end of the operating table 1, a clamping mechanism 2 is engaged with the left and right sides of the lower part of the cutting mechanism 3, and a pushing mechanism 5 is fixedly connected to the upper end of the operating table 1 on the left side of the fixing mechanism 4.

[0033] In the process of cutting a large LCD screen into narrow strips, the fixing mechanism 4 cooperates with the cutting mechanism 3 to adsorb and fix the large LCD screen, and the pushing mechanism 5 cooperates with the fixing mechanism 4 to push the LCD screen for cutting. In the process of pushing and cutting, the cutting part is continuously blown by a part of the structure in the pushing mechanism 5 to blow away the dust generated in the cutting process, so as to prevent the dust generated by the cutting from falling on the LCD screen and affecting the subsequent processing and use;

[0034] Similarly, after cutting a narrow strip, during the resetting process of the cutting mechanism 3, the uncut LCD screen on the front upper end of the operating table 1 is clamped and moved backward for a distance through cooperation with the two clamping mechanisms 2, and then continued to be fixed and cut through cooperation with the cutting mechanism 3, so as to achieve uniform and continuous cutting of large LCD screens into narrow strips, which is convenient for subsequent processing operations.

[0035] During the operation of this embodiment, through the close cooperation between the fixing mechanism 4 and the cutting mechanism 3, it is possible to achieve precise adsorption and fixation of large LCD screens, effectively reduce displacement and shaking during the cutting process, and thus improve cutting accuracy. At the same time, during the cutting process, part of the structure of the pushing mechanism 5 continuously blows air to clean dust, thereby preventing dust generated by cutting from falling on the LCD screen and reducing the possibility of contamination and damage. Similarly, the two clamping mechanisms 2 can cooperate to move the LCD screen backward for a certain distance, thereby achieving continuity and automation of the cutting process, reducing manual intervention, and improving production efficiency.

[0036] Embodiment 2: Based on embodiment 1, this embodiment is to achieve the effect of adsorbing and fixing the LCD screen during the preparation for cutting, and driving the LCD screen to move a certain distance during the cutting and resetting process.

[0037] See also Figure 3 A base 11 is fixedly connected to the middle part of the upper end of the operating table 1, a guide rod 111 is symmetrically fixedly connected to the middle and rear side of the upper end of the base 11, a soft support block 112 is fixedly connected to the front side of the upper end of the base 11, a guide rail 2 14 is fixedly connected to the middle and rear side of the upper end of the operating table 1, a guide rail 13 is fixedly connected to the middle and rear side of the upper end of the operating table 1 on the right side of the guide rail 2 14, an inclined slide plate 15 is fixedly connected to the upper end of the operating table 1 on the rear side of the base 11, and a guide groove 12 is symmetrically fixedly connected to the upper end of the operating table 1.

[0038] Specifically, during the operation of this embodiment, the base 11 cooperates with the two guide rods 111 to limit the fixing mechanism 4, so as to avoid position deviation during the mobile cutting process. At the same time, the upper end of the soft support block 112 contacts the lower end of the front side of the LCD screen to be cut, and the auxiliary fixing mechanism 4 provides certain support for the LCD screen, so as to avoid damage to the LCD screen during the cutting process.

[0039] Furthermore, the two clamping mechanisms 2 are limited by the cooperation of the two guide grooves 12. Similarly, the guide rail 1 13 and the guide rail 2 14 cooperate to limit the partial structure of the fixing mechanism 4, so that it cooperates with the cutting mechanism 3 to fix the LCD screen in preparation for cutting.

[0040] See also Figure 6 The cutting mechanism 3 includes a hydraulic cylinder 31 fixedly connected to the upper end of the operating table 1, an L-shaped rod 32 is fixedly connected to the output end of the hydraulic cylinder 31, a horizontal plate 33 is fixedly connected to the rear side of the right end of the L-shaped rod 32, a diamond knife 34 is fixedly connected to the front side of the lower end of the horizontal plate 33, a Z-shaped sliding rod 37 is fixedly connected to the middle part of the right end of the horizontal plate 33, a U-shaped rod 35 is fixedly connected to the left side of the front end of the L-shaped rod 32, and a rack 36 is symmetrically fixedly connected to the lower end of the U-shaped rod 35.

[0041] Specifically, when the entire LCD screen is to be cut, the hydraulic cylinder 1 31 is activated, so that its output end pushes the L-shaped rod 32 downward, and the L-shaped rod 32 drives the horizontal plate 33 and the U-shaped rod 35 to move downward at the same time during the downward push, and then drives the diamond knife 34 downward during the downward movement of the horizontal plate 33, until it reaches a suitable cutting height, and then the operation of the hydraulic cylinder 1 31 is suspended;

[0042] Similarly, during the descent of the U-shaped rod 35 , the U-shaped rod 35 will push the two racks 2 36 downwards. At the same time, two through holes are correspondingly opened at the upper end of the operating platform 1 to limit the two racks 2 36 during the descent.

[0043] At the same time, the Z-shaped slide bar 37 is driven to move downwards during the descending process of the cross plate 33 .

[0044] See also Figure 4 and Figure 5The fixing mechanism 4 includes a fixing plate 41 which is slidably connected to the outer surfaces of the two guide rods 111. An L-shaped plate 44 is fixedly connected to the upper end of the operating table 1. A hose 43 is fixedly connected to the front end of the L-shaped plate 44. A plurality of suction cups 42 are fixedly connected to the end of the hose 43 away from the L-shaped plate 44. The plurality of suction cups 42 are fixedly connected to the upper end of the fixing plate 41. An L-shaped plate 47 is slidably connected to the left end of the L-shaped plate 44. An air bag 45 is fixedly connected to the front end of the L-shaped plate 47 and the rear end of the L-shaped plate 44. A vertical plate 46 is fixedly connected to the right end of the L-shaped plate 47. An inclined groove 461 is provided on the upper right end of the vertical plate 46. The lower end of the vertical plate 46 is slidably connected to the outer surface of the guide rail 13. The rear end of the L-shaped plate 47 is slidably connected to the outer surface of the guide rail 14. The outer surface of the right end of the Z-shaped slide bar 37 is slidably connected to the inner surface of the inclined groove 461.

[0045] The airbag 45 and the hose 43 mentioned above are connected to the inner surfaces of the plurality of suction cups 42.

[0046] Specifically, when a large LCD screen needs to be cut into narrow strips, the LCD screen is first placed on the upper ends of the suction cups 42, and then the hydraulic cylinder 31 is activated. The output end of the hydraulic cylinder 31 pushes the L-shaped rod 32 downward, which drives the Z-shaped slide bar 37 to move downward. Then, the Z-shaped slide bar 37 cooperates with the inner surface of the inclined groove 461 during the downward sliding process, so that the vertical plate 46 is driven by the Z-shaped slide bar 37 to move backward along the outer surface of the guide rail 13;

[0047] When the vertical plate 46 is driven by the Z-shaped slide bar 37 and the inclined groove 461 to move backward along the guide rail 13, the vertical plate 46 will drive the rear end of the L-shaped plate 2 47 and the rear end of the air bag 1 45 to move backward. At this time, the front end of the L-shaped plate 1 44 and the air bag 1 45 are fixed. When the vertical plate 46 drives the L-shaped plate 2 47 to move backward, the L-shaped plate 2 47 moves along the outer surface of the guide rail 2 14 to avoid positional displacement of the L-shaped plate 2 47 during its movement.

[0048] At the same time, the rear end of the airbag 45 is driven to move backward. At this time, the airbag 45 is stretched and the air pressure inside it is reduced. At this time, a sealed space is formed between the LCD screen and the plurality of suction cups 42, the hose 43 and the rack three 53. Then, the lower end of the LCD screen is adsorbed and fixed by the hose 43 and the plurality of suction cups 42. At the same time, the cooperation of the suction of the plurality of suction cups 42 will not cause damage to the LCD screen.

[0049] See also Fig. 9 and Fig.10A hydraulic cylinder 2 51 is fixedly connected to the left side of the upper end of the operating table 1, a push plate 52 is fixedly connected to the output end of the hydraulic cylinder 2 51, a rack 3 53 is fixedly connected to the front end of the push plate 52, a gear 2 54 is meshed with the right side of the front end of the rack 3 53, a rack 4 55 is meshed with the outer surface of the gear 2 54, a telescopic box 56 is fixedly connected to the front end of the rack 4 55, a fixed plate 3 57 is fixedly connected to the left end of the telescopic box 56, a hose 2 58 is fixedly connected to the left end of the gear 2 54, a spray plate 59 is fixedly connected to the rear side of the right end of the hose 2 58, and the right end of the hydraulic cylinder 2 51 is fixedly connected to the left end of the fixed plate 2 41.

[0050] Further, when the diamond knife 34 is pushed down to a suitable cutting position, the suction cups 42 cooperate with the fixing plate 2 41 and the airbag 1 45 to fix the LCD screen, and then the diamond knife 34 and the hydraulic cylinder 2 51 are activated, and then the output end of the hydraulic cylinder 2 51 pushes the push plate 52 to the right, and then the push plate 52 pushes the fixing plate 2 41 to the right to slide right along the outer surface of the two guide rods 111, and the fixing plate 2 41 is pushed to slide to the right while cooperating with the diamond knife 34 to cut the LCD screen;

[0051] See also Fig.10 When the push plate 52 pushes the fixing plate 2 41 to cooperate with the suction cups 42 and the LCD screen to move to the right, through the setting of the hose 1 43 and the cooperation of the base 11, the hose 1 43 does not affect the movement of the fixing plate 2 41 and the suction cups 42, and at the same time, the suction cups 42 are still kept tightly adsorbed to the lower end of the LCD screen during the movement.

[0052] At the same time, when the push plate 52 pushes the fixed plate 2 41 to the right, it will drive the rack 3 53 to move in the same direction, and then drive the rack 4 55 to move to the left through the cooperation of the gear 2 54.

[0053] Similarly, a plurality of nozzles are disposed at the right end of the spray plate 59, and the spray plate 59 is disposed at an angle as a whole.

[0054] See also Fig.10 The right end of the telescopic box 56 is fixedly connected with a slider 561, the lower end of the slider 561 is slidably connected to the upper end of the base 11, the inner surface of the telescopic box 56 is fixedly connected with an airbag 2 562, the inner surface of the hose 2 58 is connected to the inner surface of the airbag 2 562, and the lower end of the fixed plate 3 57 is fixedly connected to the upper end of the operating table 1.

[0055] When the rack four 55 moves to the left and drives the right end of the telescopic box 56 to slide to the left, the gear two 54 and the left end of the airbag two 562 are fixed, and the right end of the telescopic box 56 drives the slider 561 to slide to the left, thereby squeezing the airbag two 562. At this time, the internal gas of the airbag two 562 enters the spray plate 59 through the inner surface of the hose two 58 and is sprayed out from a plurality of nozzles. Through the inclined setting of the spray plate 59, the gas sprayed from the plurality of nozzles is blown toward the diamond knife 34 and the cutting part of the LCD screen, and the dust generated during the cutting process is blown toward the upper end of the operating table 1 to prevent the dust from being scattered on the surface of the LCD screen and affecting the subsequent operations.

[0056] Similarly, after a narrow strip of the LCD screen is cut, the narrow strip of the LCD screen will fall on the upper end of the inclined slide plate 15, and due to the inclined setting of the inclined slide plate 15, the cut LCD screen will automatically slide down for unloading;

[0057] Then the output end of the second hydraulic cylinder 51 drives the push plate 52 and the second fixing plate 41 to move to the right, driving the second fixing plate 41 and the plurality of suction cups 42 to cooperate with the adsorbed LCD screen to reset.

[0058] See also Figure 7 and Figure 8 The clamping mechanism 2 includes a gear 21 meshed with the front side of the rack 236, a rack 22 meshed with the lower side of the outer surface of the gear 21, a fixed plate 23 is fixedly connected to the front end of the rack 22, a telescopic rod 26 is rotatably connected to the front side of the upper end of the fixed plate 23, a ring 25 is fixedly connected to the upper part of the outer surface of the telescopic rod 26, a fixed rod 27 is fixedly connected to the upper end of the telescopic rod 26, a soft plate 28 is fixedly connected to the upper end of the fixed rod 27 near the fixed plate 241, a limiting plate 24 is provided on the lower part of the outer surface of the telescopic rod 26, and the lower part of the rack 22 is slidably connected to the inner surface of the guide groove 12.

[0059] Specifically, when the output end of the hydraulic cylinder 1 31 pushes the L-shaped rod 32 downward, the two racks 2 36 are driven to move downward, and the gear 1 21 meshing with the rack 2 36 is driven to rotate, and the rack 1 22 meshing with the gear 1 21 is moved forward at the same time;

[0060] Furthermore, when rack 1 22 is driven forward by rack 2 36 and gear 1 21, it slides along the inner surface of guide groove 12. Rack 1 22 pushes fixed plate 1 23 forward during its forward movement, and then drives telescopic rod 26, circular ring 25, fixed rod 27 and soft plate 28 to move to the front side of the upper end of limit plate 24.

[0061] Furthermore, after the fixing plate 2 41 cooperates with the suction cups 42 to drive the LCD screen to reset, the hydraulic cylinder 1 31 is activated, and its output end drives the diamond knife 34 and the two racks 2 36 to move upward. At this time, the racks 2 36 move upward and cooperate with the gear 1 21 to move the racks 1 22 backward, which in turn drives the fixing plate 1 23, the telescopic rod 26, the fixing rod 27 and the soft board 28 to move backward;

[0062] At the same time, during the upward movement of rack 2 36, the Z-shaped slide bar 37 is also driven upward by the horizontal plate 33. At this time, the vertical plate 46 moves forward along the outer surface of guide rail 13 through the cooperation of the inclined groove 461 and the Z-shaped slide bar 37, and at the same time, the L-shaped plate 2 47 is driven to move forward along the outer surface of guide rail 2 14. During the forward movement of the L-shaped plate 2 47, the rear end of the airbag 1 45 is driven forward, thereby squeezing the gas inside the airbag 1 45, and then the hose 1 43 and the plurality of suction cups 42 cooperate to release the lock on the LCD screen.

[0063] See also Figure 8 A limiting groove 241 is provided in the middle of the upper end of the limiting plate 24, and the lower part of the outer surface of the telescopic rod 26 is slidably connected to the inner surface of the limiting groove 241. A guide plate 242 is fixedly connected to the side of the upper end of the limiting plate 24 close to the fixed plate 41, and a stopper 243 is rotatably connected to the side of the inner surface of the limiting groove 241 close to the fixed plate 41, and the lower end of the ring 25 is movably connected to the upper end of the guide plate 242.

[0064] The middle stopper 243 cooperates with the limiting groove 241 to enable the lower part of the outer surface of the telescopic rod 26 to move along the inner surface of the limiting groove 241. When the fixed plate 1 23 pushes the telescopic rod 26 to move forward, the setting of the stopper 243 enables the lower part of the outer surface of the telescopic rod 26 to move along the inclined part of the inner surface of the limiting groove 241 in a direction away from the fixed plate 2 41 and the LCD screen while moving forward. At this time, the ring 25 is separated from the upper end of the guide plate 242, and the telescopic rod 26 automatically returns to the shortest position, while driving the fixed rod 27 and the soft board 28 to be at the lowest position. When the push plate 52 pushes the fixed plate 2 41 to cooperate with the diamond knife 34 to cut the LCD screen, the height of the fixed rod 27 and the soft board 28 will not affect the movement of the LCD screen.

[0065] Furthermore, when rack 2 36 descends to cooperate with gear 1 21 and rack 1 22 to make fixed plate 1 23 push telescopic rod 26 forward, when the diamond knife 34 descends to a suitable cutting height, the telescopic rod 26 is located at the front side of the inner surface of the limiting groove 241 away from the LCD screen, and the lower end of the ring 25 is just in close contact with the lowest point of the upper end of the guide plate 242.

[0066] When a section of the LCD screen is cut, the push plate 52 drives the fixed plate 2 41 and the LCD screen to reset. At this time, the output end of the hydraulic cylinder 1 31 drives the diamond knife 34 to reset, so that the rack 2 36 is driven to move upward. At this time, the fixed plate 1 23 drives the telescopic rod 26 to move along the inclined portion of the inner surface of the limiting groove 241 to the side close to each other, and then the telescopic rod 26 drives the fixed rod 27 and the soft board 28 to move in the same direction. During the process of the telescopic rod 26 moving backward along the inclined portion of the inner surface of the limiting groove 241 close to the LCD screen, the ring 25 cooperates with the guide plate 242 to drive the upper part of the telescopic rod 26 to move upward for a distance. At this time, the telescopic rod 26 is stretched, and at the same time, the upper end of the telescopic rod 26 drives the fixed rod 27 and the soft board 28 to move in the same direction. At the same time, the two soft boards 28 that have risen will cooperate with each other to gradually clamp the two sides of the uncut LCD screen.

[0067] When the fixed plate 1 23 drives the telescopic rod 26 to move to the horizontal portion of the inner surface of the limiting groove 241, it will continue to move backwards. At this time, the two soft plates 28 clamp the LCD screen and move backwards for a distance.

[0068] See also Figure 8 The lower end of the limiting plate 24 is fixedly connected to the upper end of the operating platform 1 .

[0069] Specifically, when the ring 25 is driven by the telescopic rod 26 to slide along the upper end of the guide plate 242, the ring 25 will drive the upper part of the telescopic rod 26 to move upward for a distance.

[0070] Therefore, in the process of cutting the LCD screen, the present solution continuously blows air to the cutting part through the cooperation of the spray plate 59 to prevent dust from falling on the surface of the LCD screen. At the same time, in the process of preparing for cutting, the LCD screen is fixed through the cooperation of the vertical plate 46 and the Z-shaped slide bar 37 as well as the airbag 45, the hose 43 and a plurality of suction cups 42 to avoid damage to the LCD screen and avoid the LCD screen from shifting during the cutting process. At the same time, in the process of resetting after cutting a section of the LCD screen, the two telescopic rods 26 cooperate with the soft board 28 to clamp the LCD screen and move it backward for a distance, so as to continuously cut the entire LCD screen into narrow strips, thereby facilitating the subsequent processing of the LCD screen.
