Technical Field

[0001] This utility model relates to the field of optical adhesive cutting technology, and in particular to an automatic cutting device for OCA optical adhesive. Background Technology

[0002] Optical adhesives are key bonding materials in electronic device screen components, playing an indispensable role, especially in bonding touchscreens to display panels. Their excellent light transmittance, adhesive strength, and weather resistance make OCA optical adhesives the preferred bonding material in the manufacture of high-end electronic devices.

[0003] However, faced with the wide variety of OCA optical adhesive materials on the market, varying in thickness, and the diverse needs of customers for cutting shapes and sizes, existing cutting equipment suffers from significant shortcomings in flexibility and adaptability. Traditional cutting equipment often uses fixed molds and cutting parameters, making it difficult to cope with changes in different materials and cutting requirements. This not only limits the applicability of the cutting equipment but may also lead to a decrease in cutting accuracy and efficiency.

[0004] Furthermore, existing cutting equipment often exhibits edge curling after cutting OCA optical adhesive. Edge curling not only affects the bonding effect of screen components but can also reduce the overall performance of electronic devices and the user experience. This problem is often related to factors such as the cutting method, blade selection, and pressure control of the cutting equipment, and requires solutions through technological innovation and process improvement.

[0005] Therefore, there is a need for an automatic cutting device for OCA optical adhesive. Utility Model Content

[0006] To overcome the drawback of easy edge curling, this utility model provides an automatic cutting device for OCA optical adhesive.

[0007] An automatic cutting device for OCA optical adhesive includes a mounting base, a mounting plate, cylinders, a connecting shell, a connecting plate, a motor, a controller, a guide rod, a screw, and a cutting blade. The mounting base has a mounting plate on its top. Cylinders are symmetrically mounted front and back on the top of the mounting base. Each cylinder's piston rod has a connecting plate. A connecting shell is located between the connecting plates. The motor is mounted on the right side of the connecting shell, and the controller is mounted on the connecting shell, electrically connected to the motor. The guide rod is located inside the connecting shell, and a screw is rotatably mounted inside the connecting shell. The screw is connected to the output shaft of the motor. A cutting blade is threaded onto the screw, and the cutting blade is slidably connected to the guide rod. An anti-warping component is also included, located on the left side of the cutting blade.

[0008] As an improvement to the above solution, the anti-warping component includes a motor, a second screw, and an anti-warping plate. The motor is installed on the left side of the cutting blade, the controller is electrically connected to the motor, and the output end of the motor is provided with a second screw.

The second motor is installed on the left front side and the right front side of the top of the mounting plate. The controller is electrically connected to the second motor, and the output shaft of the second motor is equipped with a conveyor roller.

[0010] As an improvement to the above solution, it also includes a fixing plate, a second guide rod, and a limiting block. The top left and right sides of the mounting plate are equipped with fixing plates, and the fixing plates are equipped with second guide rods. The second guide rods are symmetrically slidably equipped with limiting blocks.

[0011] As an improvement to the above solution, the limit block has a telescopic structure design.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example: An automatic cutting device for OCA optical adhesive, please see below. Figures 1 to 6As shown, the device includes a mounting base 1, a mounting plate 2, a cylinder 3, a connecting shell 4, a connecting plate 401, a motor 5, a controller 6, a guide rod 7, a screw 8, a cutting blade 9, a motor 10, a second screw 11, an anti-tilting plate 12, a second motor 13, a conveyor roller 14, a fixing plate 15, a second guide rod 16, and a limiting block 17. The mounting base 1 serves as the basic support structure for the entire cutting device, used to install and fix other components. The mounting plate 2 is connected to the top of the mounting base 1. Cylinders 3 are symmetrically and vertically mounted upwards on the top of the mounting base 1. The piston rods of the cylinders 3 extend upwards and pass through the front and rear sides of the top of the mounting plate 2. The piston rods of the cylinders 3 are all connected to the connecting plates 401. The connecting shells 401 are connected between the connecting plates 401, and the connecting shells 4 provide installation space. A gap is provided between the connecting shell 4 and the mounting plate 2 to facilitate the passage of OCA optical adhesive. A motor 5 is horizontally mounted on the right side of the connecting shell 4, and a controller 6 is mounted on the top of the mounting shell. The controller 6 is electrically connected to the motor 5. A guide rod 7 is horizontally connected inside the connecting shell 4, and a screw 8 is horizontally rotatably connected inside the connecting shell 4. The screw 8 is connected to the output shaft of the motor 5. The screw 8 and the guide rod 7 are symmetrically designed. A cutting blade 9 is threaded onto the screw 8. The cutting blade 9 is used to cut the OCA optical adhesive. The cutting blade 9 is slidably connected to the guide rod 7. The motor 5 provides power to the screw 8. By rotating the screw 8, the cutting blade 9 is driven to move left and right on the guide rod 7. Vertical power is provided by the cylinder 3. The piston rod's extension and retraction movement drives the connecting plate 401 and connecting shell 4 to move up and down, thereby adjusting the height of the cutting blade 9. A motor 10 is longitudinally mounted at the center left side of the cutting blade 9. The controller 6 is electrically connected to the motor 10. The output shaft of the motor 10 is connected to a screw 11. Both ends of the screw 11 are threadedly connected to anti-tilting plates 12. The bottom of the anti-tilting plate 12 has a sliding pad to reduce the friction between the anti-tilting plate 12 and the OCA optical adhesive, preventing the OCA optical adhesive from getting stuck. The motor 10 drives the screw 11 to rotate, thereby moving the anti-tilting plate 12 to adjust its position. The anti-tilting plate 12 prevents the OCA optical adhesive from lifting during cutting, ensuring cutting quality. The mounting plate 2 has anti-tilting plates on its top left and right front sides. Each mounting plate 2 is equipped with a second motor 13, and the controller 6 is electrically connected to the second motor 13. The output shaft of each second motor 13 is connected to a conveyor roller 14, which conveys the OCA optical adhesive to the cutting position. The second motor 13 provides power to the conveyor roller 14, and by rotating the conveyor roller 14, the OCA optical adhesive is conveyed. Fixing plates 15 are connected to the top left and right sides of the mounting plate 2, positioned between the two conveyor rollers 14. Guide rods 16 are connected to the top of each fixing plate 15, and limit blocks 17 are symmetrically slidably connected to each guide rod 16. The limit blocks 17 have a telescopic structure design to facilitate the entry of the OCA optical adhesive and to restrict the position of the OCA optical adhesive during conveying, ensuring cutting accuracy.Its telescopic design facilitates the insertion and positioning of OCA optical adhesive.

[0026] When using an automatic cutting device to cut OCA optical adhesive, first adjust the position of the limit block 17 according to the size of the OCA optical adhesive material to be cut to ensure that the material remains in the correct position during the conveying process. Next, turn on the controller 6, start the equipment power, and set the required cutting parameters, such as cutting width and cutting speed, on the controller 6 to meet production requirements.

[0027] Subsequently, the OCA optical adhesive material is smoothly drawn onto the conveyor roller 14, ensuring that the material is flat and aligned. The position of the limit block 17 is then checked again to ensure the stability of the material during the conveying process.

[0028] Controller 6 starts motor 13, causing it to rotate and drive conveyor roller 14 to smoothly transport the OCA optical adhesive material to the cutting position. Simultaneously, motor 5 also starts working, driving screw 8 to rotate. As screw 8 rotates, cutting blade 9 moves left and right on guide rod 7, beginning to cut the OCA optical adhesive material.

[0029] The piston rod of cylinder 3 adjusts the position of the cutting blade 9 according to the preset height to ensure accurate cutting depth and meet production requirements. At the same time, motor 10 drives screw 11 to rotate, adjusting the position of anti-tilting plate 12 to accommodate OCA optical adhesive materials of different widths, effectively preventing the OCA optical adhesive from tilting during the cutting process and ensuring cutting quality.

[0030] Once the OCA optical adhesive material has been completely cut, motor 5, motor 13, and cylinder 3 should be shut off immediately to stop the cutting operation. Then, remove the cut OCA optical adhesive material to prepare for the next step of processing or assembly.

[0031] After completing the cutting task, in order to ensure the long-term stable operation of the equipment and extend its service life, the equipment should be cleaned promptly to remove residual adhesive residue and dust. This step is crucial for maintaining the cleanliness and precision of the equipment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
