Detailed Implementation
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0026] Example 1, referring to Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a cutting device for LCD screen production, which can effectively adjust the device. It includes a base 1, a cutting mechanism 2 disposed outside the base 1, the cutting mechanism 2 cutting the LCD screen by means of a telescopic cylinder, a moving frame and a cutting flywheel, and an adjustment component 3 disposed inside the base 1.
[0027] The adjustment assembly 3 includes a turntable 32, a connecting rod 33 disposed on the top of the turntable 32, the turntable 32 being disposed inside the base 1, and the turntable 32 being movably connected to the connecting rod 33 via a rotating shaft, a pull rod 34 disposed at one end of the connecting rod 33, the connecting rod 33 being movably connected to the pull rod 34 via a rotating shaft, a movable plate 35 disposed at one end of the pull rod 34, the movable plate 35 being connected to the pull rod 34 via bolts, a slide block 36 disposed outside the movable plate 35, the slide block 36 being bolted to the top outer wall of the movable plate 35, a guide groove 37 opened on the top of the base 1, and a sliding tube 38 disposed inside the guide groove 37, the guide groove 37 and the sliding tube 38 being slidably connected, and the sliding tube 38 being slidably connected to the slide block 36;
[0028] The slide tube 38 is slidably connected inside the slide block 36. The slide tube 38 and the guide groove 37 are in sliding fit. The rotation of the turntable 32 drives the connecting rod 33 to move. The connecting rod 33 then drives the pull rod 34 and the moving plate 35 to move together. With the sliding connection between the slide tube 38, the slide block 36, and the guide groove 37, the suction cup 39 is finally driven to complete the action of bringing them together.
[0029] Specifically, the adjustment component 3 also includes a motor 31, which is bolted to the inside of the base 1. The base 1 is also equipped with an air pump 310. The motor 31 is bolted to the inside of the base 1, and the output end of the motor 31 is connected to the turntable 32 via a coupling. The air pump 310 is also bolted to one side of the inside of the base 1.
[0030] Furthermore, the vacuum pump 310 is connected to the slide tube 38 via a hose, and the slide tube 38 is connected to the suction cup 39. When the vacuum pump 310 is started, it can use the hose 38 to inject gas into the interior of the slide tube 38.
[0031] When in use, when the motor 31 installed inside the base 1 is started, the rotational power output by the motor 31 is transmitted through the torque of the coupling, which smoothly drives the turntable 32 to rotate at a constant speed inside the base 1. During the continuous rotation of the turntable 32, its top is traction-type motion generated by the connecting rod 33 connected by the movable connection. One end of the connecting rod 33 moves in a circular trajectory with the turntable 32, while the other end is flexibly connected to the pull rod 34 through the rotating shaft. This connection method effectively converts the circular motion into lateral reciprocating left and right movement, so that the pull rod 34 slides stably along the horizontal guide structure inside the base 1.
[0032] During the lateral movement of the pull rod 34, the moving plate 35, which is fixed to its end by bolts, moves laterally left and right simultaneously. The slider at the bottom of the moving plate 35 is precisely matched with the slide rail inside the base 1 to ensure that there is no deviation or jamming during the movement. As the moving plate 35 moves, the slide block 36, which is fixed to its top by bolts, moves accordingly. The sliding channel inside the slide block 36 forms a sliding connection with the slide tube 38, so that the slide tube 38 can move smoothly under the constraint of the slide block 36.
[0033] During the movement of the slide tube 38, the guide block at its bottom is embedded in the pre-set guide groove 37 of the base 1. The guide groove 37 has a symmetrical contraction design. Through the limiting and guiding effect of this guide structure, the slide tubes 38 on both sides gradually approach each other and precisely converge during the lateral movement. The suction cup 39, which is detachably connected to the top of the slide tube 38 by a thread, moves synchronously with the slide tube 38. When the suction cup 39 moves to the bottom of the LCD screen and is attached to the surface of the screen, the matching vacuum pump 310 is activated. The vacuum pump 310 is connected to the outer wall of the slide tube 38 through a sealed hose. Using the negative pressure suction generated by the vacuum pump 310, the air between the suction cup 39 and the contact surface of the LCD screen is quickly extracted through the internal channel of the slide tube 38 and the hose, so that a stable vacuum environment is formed at the contact surface, thereby achieving firm fixation and adsorption of the LCD screen and ensuring that the screen does not shift or get damaged during subsequent processing or transportation.
[0034] In summary, the adjustment component 3 has a built-in turntable 32 that can rotate flexibly. When the user rotates the turntable 32, it directly drives the connecting rod 33 to generate a linkage motion. The connecting rod 33 is stably connected to the pull rod 34 through the end connector, converting the rotational power of the turntable 32 into a linear driving force, which in turn drives the pull rod 34 to push the moving plate 35 to move along a preset trajectory. The bottom of the moving plate 35 is equipped with a slide block 36, which forms a smooth fit with the guide rail of the device base, ensuring the stability and accuracy of the moving plate 35 during movement. At the same time, the moving plate 35 is provided with a slide block 36 and a slide tube 38, and the slide tube 38 is precisely embedded in the guide groove 37. The guide groove 37 provides precise movement for the slide tube 38. To prevent deviation, a suction cup 39 is installed at the end of the slide tube 38. The suction cup 39 is a key component that contacts the LCD screen. Through the continuous transmission of the turntable 32, connecting rod 33, pull rod 34, moving plate 35, and slide base 36, combined with the guiding and limiting effect of the guide groove 37 on the slide tube 38, the slide tube 38 will drive the suction cup 39 to move flexibly in the forward, backward, left, and right directions. This design allows users to quickly adjust the position of the suction cup 39 simply by rotating the turntable 32 without complicated operations. Whether it is a small portable LCD screen or a large display panel, it can be accurately adapted through this transmission structure, which greatly improves the versatility and ease of operation of the device and meets the needs of use in different scenarios.
[0035] Example 2, refer to Figure 2 and Figure 5 This is the second embodiment of the present invention. Unlike the previous embodiment, it solves the problem of dustproofing the device.
[0036] Specifically, a dustproof component 4 is provided on the top of the base 1. The dustproof component 4 includes a mounting base 41, which is installed on the top of the base 1 by bolts. Rotation grooves 42 are provided on the inner walls on both sides of the mounting base 41, and the rotation base 41 is set on the top outer wall of the base 1 near the guide groove 37.
[0037] Furthermore, a take-up roller 43 is provided inside the rotating groove 42. The take-up roller 43 is set inside the rotating groove 42 by a torsion spring. The take-up roller 43 is movably installed inside the rotating groove 42 by the action of the torsion spring. The rotating groove 42 is opened on the outer wall of one side adjacent to the rotating seat 41. The opening of the rotating groove 42 allows the take-up roller 43 to rotate inside the rotating groove 42.
[0038] The outer wall of the take-up roller 43 is provided with a dustproof belt 44, and a pull seat 45 is provided at one end of the dustproof belt 44. The dustproof belt 44 is provided on the outer wall of the take-up roller 43, so the dustproof belt 44 will drive the take-up roller 43 to rotate during the movement of the dustproof belt 44.
[0039] Preferably, the pull seat 45 is provided with a sliding plate 46 on its outside. The sliding plate 46 is slidably connected to the mounting base 41. When the pull seat 45 moves, the pull seat 45 will drive the sliding plate 46 on its outside to move. When the sliding plate 46 moves, it will slide on the outer wall of the mounting base 41. When the pull seat 45 moves, it will drive the dustproof belt 44 to move. The dustproof belt 44 will drive the take-up roller 43 to rotate inside the rotating groove 42.
[0040] It should be noted that a through groove 47 is provided on the top of the pull seat 45, and the slide tube 38 passes through the interior of the through groove 47. The opening of the through groove 47 can provide an installation position for the slide tube 48, so that the pull seat 45 can move effectively when it moves.
[0041] The rest of the structure is the same as in Example 1.
[0042] When the slide tube 38 starts moving, its special structural design allows it to precisely pass through the through groove 47. This embedded assembly provides a stable foundation for power transmission, allowing the slide tube 38 to efficiently transmit power to the connected pull seat 45 through the limiting and guiding effect of the through groove 47 during movement. This directly drives the pull seat 45 to move synchronously. As the pull seat 45 follows the slide tube 38, since the pull seat 45 and the slide plate 46 adopt a rigid connection structure, they form a stable linkage. Therefore, the pull seat 45 will synchronously drive the slide plate 46 to perform corresponding movements. The movement trajectory of the slide plate 46 is subject to the sliding connection with the mounting base 41, which allows the pull seat 45 to maintain a smooth and precise sliding on the surface of the mounting base 41, effectively avoiding movement deviation and ensuring the stability of the entire transmission link.
[0043] At the same time, the pull seat 45 also pulls the dustproof belt 44 synchronously when it moves. The dustproof belt 44, as a component that combines protection and transmission functions, is fixed at one end to the pull seat 45 and wrapped around the take-up roller 43 at the other end. When the pull seat 45 drives the dustproof belt 44 to move, the dustproof belt 44 will generate a uniform tension on the take-up roller 43, thereby driving the take-up roller 43 to rotate along its own axis. The take-up roller 43 is assembled inside the preset rotating groove 42 of the mounting base 41, which provides a stable rotation for the take-up roller 43. The torsion spring provides support and reduces frictional resistance during rotation, ensuring that the take-up roller 43 can rotate flexibly and smoothly. In addition, the shaft end of the take-up roller 43 is equipped with a torsion spring. When the slide tube 38 drives the pull seat 45 and the dustproof belt 44 to rotate the take-up roller 43, the torsion spring will undergo elastic deformation and store elastic potential energy. When the slide tube 38 moves in the opposite direction or the external force disappears, the torsion spring will release the stored elastic potential energy, drive the take-up roller 43 to rotate in the opposite direction and reset, thereby driving the dustproof belt 44 to be wound up and reset synchronously.
[0044] In summary, through the dustproof component 4, when the slide tube 38 is in motion, the slide tube 38 can drive the pull seat 45 to move. During the movement of the pull seat 45, the pull seat 45 can drive the slide plate 46 on its top outer wall to move. During the movement of the slide plate 46, the slide plate 46 can slide on the outer wall of the mounting base 41. During the movement of the pull seat 45, the pull seat 45 will drive the dustproof belt 44 to move. During the movement of the dustproof belt 44, the dustproof belt 44 will drive the take-up roller 43 to rotate. During the rotation of the take-up roller 43, the take-up roller 43 will rotate inside the rotating groove 42 using the action of the torsion spring. This arrangement allows the device to effectively prevent dust after adjustment, thereby improving the practicality of the device.
