Description

Technical Field

[0001] This utility model relates to the technical field of display screen film processing equipment, specifically a segmentation device for display screen processing. Background Technology

[0002] In the manufacturing process of modern display devices, the precise cutting of flexible materials such as polarizers, touch films, thin-film encapsulation layers, conductive films (such as ITO films), and optical composite films is a key step in realizing high-performance display modules. Existing film cutting equipment mostly uses mechanical blades or laser cutting methods to complete the fixed-length or fixed-shape division of film materials through a single pressure cutting or scanning path.

[0003] In the existing technology, some traditional cutting devices use fixed cutting molds and simple reciprocating motor structures, which cannot achieve high-frequency and controllable cutting motion. They are difficult to meet the current cutting needs of multi-specification and multi-layer composite membrane materials. In particular, when dealing with membrane materials of different thicknesses and mechanical properties, there are problems such as the inability to adjust the cutting depth, incomplete material cutting or severe cutting damage, which affect the accuracy and yield of finished products.

[0004] Furthermore, some equipment lacks an effective separation structure for forming material and waste, making it difficult to automatically separate the finished product and waste edges after film cutting, relying on manual sorting, which increases production costs and error risks. At the same time, the lack of a mechanism for handling residual film edges after cutting can easily cause accumulation or blockage, affecting the stable operation of the equipment.

[0005] To address the aforementioned issues, there is an urgent need for an automated cutting device with a compact structure, stable and adjustable cutting action, and applicability to various display film materials. This device would improve the precision, efficiency, and process adaptability of film cutting, and solve problems such as poor cutting compatibility, difficulty in material separation, and reliance on manual operation in existing technologies. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0007] To address the problems of poor compatibility of existing membrane cutting devices, low efficiency in separating forming and waste materials, and insensitive structural response, this invention provides a segmentation device that integrates pressing, cutting, conveying, and pneumatic separation, offering significant advantages such as precise adjustment, efficient cutting, and a high degree of automation.

[0008] The device mainly includes a frame, a cutting assembly, a cutting table, an input roller assembly, an output roller assembly, and auxiliary modules such as a fan assembly and a forming hopper.

[0009] In a preferred embodiment, the frame is further configured such that a cutting platform is mounted on its surface, and an input roller group and an output roller group are respectively provided on both sides of the cutting platform for conveying the film material in and out; the input roller group and the output roller group include a drive roller and a reduction motor to realize continuous and stable conveying of the film material.

[0010] In a preferred example, the cutting table is further configured such that: a cutting groove is provided on the top of the cutting table to facilitate the pressing and engagement of the cutting die during the cutting action, thereby achieving complete segmentation of the film material; and a fan assembly and a forming hopper are provided on both sides for pumping out and collecting the forming material.

[0011] In a preferred embodiment, the pressure cutting assembly is further configured as follows: the pressure table, the drive motor, the active plate, and the cutting die; the output shaft of the drive motor is connected to a shaft, which drives the connecting rod to move up and down reciprocally, thereby realizing the periodic driving of the active plate.

[0012] In a preferred example, the pressure table is further configured such that the pressure table is connected to the active plate by four tie rods, the lower end of the tie rods slides through the active plate, and a spring is provided to provide a reset force, so that the pressure table and the cutting die cooperate to form a stable periodic pressing and cutting structure.

[0013] In a preferred example, the die is further configured such that: the bottom surface of the die is provided with a cutter that precisely corresponds to the cutting groove on the cutting table to ensure consistent cutting of the film material; the top of the pressure table is provided with several adjustment components, which are electric lead screws or push rods, used to adjust the initial height of the die to adapt to film materials of different thicknesses.

[0014] Specifically, the membrane material is fed into the cutting area by the input roller group. Driven by the drive motor, the cutting die performs periodic pressing and cutting motion to divide the membrane material into sections. The divided membrane material is then transmitted out through the output roller group. The formed part is pumped into the forming hopper by the fan assembly for centralized collection. Waste material is automatically peeled off and discharged, realizing automated and highly efficient membrane material dividing operation.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, by setting a tie rod and spring connection structure between the active plate and the pressure table, and cooperating with the transmission mechanism composed of the drive motor, shaft and connecting rod, the high-frequency reciprocating pressing action of the pressing and cutting component can be realized, which can effectively improve the cutting efficiency and accuracy of the display screen film material, adapt to a variety of film layer structures with different materials and thicknesses, and significantly improve the practicality and adaptability of the device.

[0017] 2. In this utility model, the cutting die is set on the bottom surface of the pressure table, and the cutting groove structure on the top surface of the cutting table seat realizes the precise cutting of the membrane material. With the adjustment component, the cutting height of the cutting die can be flexibly adjusted to ensure the compatibility of cutting membrane materials of different thicknesses and avoid the problem of not cutting through or cutting through the substrate. At the same time, by setting the fan component and the forming hopper for use together, the automatic forming collection and waste separation of the membrane material after segmentation can be effectively realized, improving the membrane material processing efficiency and reducing manual intervention, further enhancing the stability and intelligence level of the system operation.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of a display screen processing dividing device provided by the present invention.

[0029] Combination Figures 1-5 As shown, the present invention provides a display screen processing slitting device, including a frame 100 and a cutting assembly 200. A cutting table 110 is fixedly installed on the surface of the frame 100, and an input roller group 120 and an output roller group 130 are provided on the top surface of the frame 100 on both sides of the cutting table 110. A fan assembly 111 and a forming hopper 112 are respectively provided on both sides of the cutting table 110, for realizing the separation and collection of the forming material and waste material after the film material is slitted.

[0030] The pressure cutting assembly 200 includes a pressure table 210, a drive motor 220, an active plate 230, and a cutting die 240 fixed to the bottom surface of the pressure table 210. The pressure table 210 is arranged relative to the top surface of the active plate 230, and each of the four corners of the pressure table 210 is fixedly connected with a pull rod 231. The bottom end of the pull rod 231 slides through the active plate 230, and a spring 232 is movably sleeved on the surface of the pull rod 231. The top end of the spring 232 is fixedly connected to the bottom surface of the active plate 230 to provide elastic buffering for the pressure cutting process.

[0031] The output end of the drive motor 220 is connected to a shaft 221. A connecting rod 222 is rotatably sleeved on the surface of the shaft 221. The top end of the connecting rod 222 is movably connected to the bottom surface of the drive plate 230. When the drive motor 220 starts, it drives the shaft 221 to rotate, which in turn drives the connecting rod 222 to move up and down reciprocally, so that the drive plate 230 can achieve periodic reciprocating motion.

[0032] The bottom surface of the cutting die 240 is provided with a cutting blade, and the top surface of the cutting platform 110 is provided with a cutting groove corresponding to the cutting blade, so as to ensure the precise alignment and pressing of the die during the cutting process and achieve stable segmentation of the film material.

[0033] Furthermore, the blower assembly 111 is a blower structure and is arranged on one side of the cutting table 110 relative to the forming hopper 112. It is used for pumping out the forming material for cutting, while the forming hopper 112 is used for receiving the forming material.

[0034] Furthermore, both the input roller group 120 and the output roller group 130 include several drive rollers and a geared motor. The geared motor drives the drive rollers to rotate and transport the film material, ensuring stable transport of the film material before and after cutting. This structure is suitable for various display screen films such as polarizers, thin film encapsulation layers, touch electrode films / ITO films, PMMA, PC, or composite optical films.

[0035] The pull rod 231 is fixed at the four corners of the pressure table 210 and slides through the cutting table base 110 and the active plate 230. The bottom end of the spring 232 is fixedly connected to the bottom end of the pull rod 231, and the top end abuts against the surface of the active plate 230 to form a rebound buffer effect.

[0036] The shaft 221 is provided with a curved roller sleeve, and the outer circumference of the curved roller sleeve is offset from the center of the shaft 221. The curved roller sleeve is rotatably sleeved on the inner side of the connecting rod 222, thereby driving the drive plate 230 to generate reciprocating motion through eccentric rotation. The bottom end of the drive plate 230 is also rotatably installed with a shaft pin sleeved on the inner side of the connecting rod 222 to improve transmission stability.

[0037] In order to adjust the initial cutting position of the cutting die 240, a number of adjustment components 241 are fixedly installed on the top surface of the pressing table 210. The bottom end of the adjustment component 241 is fixedly connected to the surface of the cutting die 240. The adjustment component 241 can be an electric lead screw or push rod structure. By adjusting its extension length, it can be used to adapt the cutting of film materials of different thicknesses.

[0038] In summary, this embodiment fully supports all the claims and ensures the feasibility, stability and adaptability of this utility model in actual processing.

[0039] Working principle and usage process of this utility model:

[0040] During use, the film materials required for the production of the display screen, such as polarizing film, touch film, and encapsulation film, are first transported to the surface of the cutting table 110 via the input roller group 120. The input roller group 120 is driven by a geared motor to rotate the internal transmission rollers, thereby achieving a stable supply of film materials.

[0041] After the membrane material enters the cutting area, the drive motor 220 starts, and the shaft 221 connected to its output shaft rotates, thereby causing the linkage rod 222 to move up and down reciprocally, which in turn drives the active plate 230 to reciprocate. Under the combined action of the spring 232 and the pull rod 231, the pressure table 210 is driven to perform reciprocating punching motion during the membrane material conveying motion, carrying the cutting die 240 to complete the periodic pressing and cutting action. The cutter is pressed into the cutting groove on the top surface of the cutting table 110, realizing the precise segmentation of the membrane material.

[0042] After the membrane material is cut, the waste material is output through the output roller group 130. The formed material is separated from the surface of the waste membrane and falls into the forming hopper 112 for collection by the blower assembly 111.

[0043] In addition, to ensure the accuracy of the cutting position of the die 240, the device is equipped with several adjustment components 241, which can flexibly adjust the initial cutting height of the die through an electric lead screw or push rod structure to adapt to film materials of different thicknesses.

[0044] In summary, this device achieves efficient and controllable film material cutting through the reciprocating drive structure of the cutting component 200 and the precise cooperation of the cutting die. At the same time, combined with the fan component and roller conveying system, it completes the automated segmentation process of key film materials for display screens, demonstrating good adaptability and production efficiency.
