Description

Technical Field

[0001] This utility model relates to the field of optical adhesive slitting machine technology, specifically to an optical adhesive slitting machine. Background Technology

[0002] Optical adhesives, as key materials for achieving thinness, flexibility, and high reliability in modern smart devices, are widely used in the lamination and bonding of core components such as touch displays, flexible OLEDs, and glass covers. The precision and quality of their slitting process directly determine the yield of subsequent bonding and the performance of the final product. With the accelerated iteration of the consumer electronics industry and the increasing diversity of product models, the demand for small-batch, multi-specification, and ultra-high-precision optical adhesive slitting is becoming increasingly urgent. While traditional slitting equipment can meet basic processing needs, it has shown its inadequacy in handling rapid production changeovers, extreme precision, and flexible manufacturing.

[0003] In the field of optical adhesive and tape slitting, the adjustment efficiency and precision of the slitting cutters directly determine the flexibility and production efficiency of the equipment in adapting to multiple specifications. Existing technologies, such as the utility model patent with authorization announcement number CN219259097U, disclose a multi-set tape slitting cutter that is easy to adjust. It uses a drive motor to move a threaded block on a threaded rod, thereby adjusting the blade spacing. While this improves the convenience of adjustment to some extent, this approach still has significant limitations in practice: its adjustment is usually performed on a single or paired blade. When multiple sets of blades need to be adjusted simultaneously to achieve a new equidistant slitting specification, it is often necessary to position and adjust each set of blades individually or in groups. This process is cumbersome and time-consuming, and it is difficult to guarantee the precise consistency and equal height of all blade spacing, thus restricting the overall efficiency of the equipment under frequent production change conditions. Therefore, we propose an optical adhesive slitting machine. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides an optical adhesive slitting machine, including a mounting frame and a cutting blade. Multiple sets of equidistantly distributed adjusting frames are slidably mounted on the mounting frame. The cutting blade can be mounted on the adjusting frames. The mounting frame is provided with a pushing mechanism for adjusting the distance between the multiple sets of adjusting frames. Two sets of cross-distributed connecting rods are rotatably mounted on each of the multiple sets of adjusting frames. The ends of the connecting rods on adjacent sets of adjusting frames are rotatably connected by a rotating shaft.

[0005] In some embodiments, the pushing mechanism includes a mounting rod fixedly mounted on a mounting frame, two sets of symmetrically distributed first push rods are slidably mounted inside the mounting rod, and a second push rod is slidably mounted inside each of the two sets of first push rods. The outer ends of the two sets of second push rods are respectively fixedly connected to two sets of outer adjustment frames.

[0006] In some embodiments, a bidirectional screw is rotatably installed inside the mounting rod, and a screw tube is rotatably installed inside each of the two sets of first push rods. The two ends of the bidirectional screw pass through the two sets of first push rods respectively and are threadedly connected to the two sets of first push rods respectively. The two sets of screw tubes pass through the corresponding second push rods respectively and are threadedly connected to the second push rods.

[0007] In some embodiments, the bidirectional screw has two sets of symmetrically distributed keyways, and the solenoid has two sets of symmetrically distributed key blocks. The key blocks and keyways are correspondingly arranged, and the solenoid is slidably sleeved with the bidirectional screw through the key blocks and keyways.

[0008] In some embodiments, two sets of symmetrically distributed clamping frames are slidably mounted on the adjusting frame, and retaining rings are rotatably mounted on both sets of clamping frames. The cutting blade is movably engaged with the two sets of retaining rings respectively. A bidirectional lead screw is rotatably mounted inside the adjusting frame. The two ends of the bidirectional lead screw pass through the two sets of clamping frames respectively and are threadedly connected to the two sets of clamping frames respectively. A first bevel gear is sleeved on the bidirectional lead screw.

[0009] In some embodiments, a second bevel gear that meshes with the first bevel gear is rotatably mounted inside the adjustment frame, and the second bevel gear is rotatably connected to the adjustment frame via a handle.

[0010] In some embodiments, two sets of symmetrically distributed turntables are rotatably mounted on the mounting frame. A drive rod is slidably engaged on each of the two sets of turntables. The drive rod is slidably engaged with multiple sets of cutting blades. A toothed ring is sleeved on the left turntable. A drive wheel is rotatably mounted inside the mounting frame and is meshed with the toothed ring.

[0011] This utility model has at least the following beneficial effects: 1. This solution utilizes a precision driving mechanism comprised of a mounting rod, a bidirectional screw, a first push rod, a second push rod, and a solenoid tube. Simply rotating a single bidirectional screw synchronously drives all adjusting frames to slide along the mounting frame, achieving synchronous, equidistant, and stepless adjustment of the spacing between multiple sets of cutting blades. This significantly improves the efficiency of changeover adjustments and, through mechanical linkage, ensures precise consistency in the spacing of all slits, effectively overcoming the inefficiency and cumulative errors associated with individual adjustments in existing technologies. Simultaneously, the cross-link structure formed by the connecting rods plays a crucial role in stabilization and guidance during adjustment, further ensuring the synchronicity and stability of the movement of all adjusting frames, thereby maintaining the equal height and straightness of the cutting blade assembly.

[0012] 2. By setting a bidirectional lead screw to drive the two clamping frames to move towards or away from each other, and utilizing the retaining rings on the clamping frames to engage with the cutting blade, rapid centering, clamping, and locking of the cutting blade is achieved. During operation, simply drive the handle to rotate the second bevel gear, which meshes with the first bevel gear, thereby rotating the bidirectional lead screw to complete the precise positioning and stable fixation of the cutting blade. This structure not only has high clamping efficiency, ensuring that the central axis of the cutting blade always coincides with the clamping center, avoiding runout and wear caused by installation eccentricity, but also has a compact structure and is easy to operate, greatly improving the convenience of tool replacement and maintenance. In addition, the drive mechanism composed of a turntable, drive rod, gear ring, and drive wheel can synchronously drive all cutting blades to rotate stably, ensuring uniform and reliable power transmission for slitting.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figures 1-3This utility model provides a technical solution: an optical adhesive slitting machine, including a mounting frame 1 and a cutting blade 2. Multiple sets of equidistantly distributed adjusting frames 3 are slidably mounted on the mounting frame 1. The cutting blade 2 can be mounted on the adjusting frames 3. The mounting frame 1 is provided with a pushing mechanism 9 for adjusting the spacing between the multiple sets of adjusting frames 3. Two sets of cross-distributed connecting rods 4 are rotatably mounted on each set of adjusting frames 3. The ends of the connecting rods 4 on adjacent sets of adjusting frames 3 are rotatably connected by a rotating shaft. When it is necessary to adjust the spacing between all the cutting blades 2, the pushing mechanism 9 is driven to make the two outermost sets of adjusting frames 3 slide towards or away from each other on the mounting frame 1. During this process, the linkage mechanism formed by the cross-distributed connecting rods 4 synchronously and equidistantly transmits the movement of the outer adjusting frames 3 to all the intermediate adjusting frames 3, thereby achieving synchronous and equidistant movement of all adjusting frames 3, ultimately setting the slitting spacing efficiently and accurately.

[0017] The pushing mechanism 9 includes a mounting rod 901 fixedly mounted on the mounting bracket 1. Two sets of symmetrically distributed first push rods 902 are slidably mounted inside the mounting rod 901. A second push rod 903 is slidably mounted inside each set of first push rods 902. The outer ends of the two sets of second push rods 903 are fixedly connected to two sets of outer adjusting brackets 3, respectively. A bidirectional screw 904 is rotatably mounted inside the mounting rod 901. A screw tube 905 is rotatably mounted inside each set of first push rods 902. Both ends of the bidirectional screw 904 pass through the two sets of first push rods 902 and are threadedly connected to them, respectively. The two sets of screw tubes 905 pass through the corresponding second push rods 903 and are threadedly connected to them, respectively. Two sets of symmetrically distributed keyways 906 are provided on the bidirectional screw 904. Two sets of symmetrically distributed key blocks 907 are provided inside the screw tubes 905. The keyway 906 and key 7 are correspondingly set. The screw tube 905 is slidably sleeved with the bidirectional screw 904 through the key block 907 and keyway 906. When the bidirectional screw 904 is rotated, since the threads at both ends are in opposite directions, it drives the two sets of first push rods 902 to make linear movements in opposite or opposite directions within the mounting rod 901. At the same time, since the screw tube 905 is slidably sleeved on the bidirectional screw 904 through the cooperation of the key block 907 and keyway 906, the rotation of the bidirectional screw 904 will drive the two sets of screw tubes 905 to rotate synchronously. The rotation of the screw tube 905 will drive the second push rod 903, which is threadedly connected to it, to slide inside, thereby transmitting the motion to the outer adjustment frame 3. This design decomposes the single rotational motion of the bidirectional screw 904 into two-stage telescopic motion of the first push rod 902 and the second push rod 903, realizing a wide range, synchronous and precise displacement adjustment of the adjustment frame 3.

[0018] Example 2: Please refer to Figure 4 , Figure 5Two sets of symmetrically distributed clamping frames 10 are slidably mounted on the adjusting frame 3. Each clamping frame 10 has a retaining ring 11 rotatably mounted on it. The cutting blade 2 is movably engaged with the two sets of retaining rings 11. A bidirectional lead screw 12 is rotatably mounted inside the adjusting frame 3. Both ends of the bidirectional lead screw 12 pass through the two clamping frames 10 and are threadedly connected to them. A first bevel gear 13 is sleeved on the bidirectional lead screw 12. A second bevel gear 14, meshing with the first bevel gear 13, is rotatably mounted inside the adjusting frame 3. The second bevel gear 14 is connected to the adjusting frame via a handle 15. 3. Rotary connection: When installing or replacing the cutting blade 2, place both ends of the blade shaft between the two retaining rings 11. Rotate the handle 15 to drive the second bevel gear 14 to rotate. The second bevel gear 14 drives the first bevel gear 13, which meshes with it, to rotate, thereby driving the bidirectional lead screw 12 to rotate. Since the threads at both ends of the bidirectional lead screw 12 turn in opposite directions, the two assembly clamps 10 are driven to slide towards each other along the adjusting frame 3. The retaining rings 11 securely clamp the two ends of the cutting blade 2. This process achieves rapid centering, clamping, and locking of the cutting blade 2, ensuring installation accuracy and stability.

[0019] Two symmetrically distributed turntables 5 are rotatably mounted on the mounting frame 1. Drive rods 6 are slidably engaged with each turntable 5, and these drive rods 6 are slidably engaged with multiple sets of cutting blades 2. A toothed ring 7 is fitted onto the left turntable 5. A drive wheel 8 is rotatably mounted inside the mounting frame 1, and the drive wheel 8 meshes with the toothed ring 7. When the equipment is working, external power drives the drive wheel 8 to rotate, which in turn drives the meshing toothed ring 7 to rotate, thereby driving the left turntable 5 to rotate. The left turntable 5 transmits torque to the right turntable 5 through the drive rod 6, causing the two turntables 5 to rotate synchronously. As the drive rod 6 rotates with the turntable 5, its slidably engaged portion with the cutting blades 2 synchronously transmits rotational power to all the cutting blades 2, causing them to rotate together to perform slitting operations. The slidably engaged structure ensures that the drive rod 6 can still reliably transmit power when adjusting the blade spacing.
