Description

Technical Field

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

[0002] OCA optical adhesive is a special adhesive used to bond transparent optical components (such as lenses). It is required to be colorless and transparent, with a light transmittance of over 90%, good bonding strength, and the ability to cure at room temperature or medium temperature with low curing shrinkage. OCA optical adhesive is one of the important raw materials for touch screens. It is usually made into a substrate-free form of optical acrylic adhesive and a release film is laminated on the top and bottom layers to form a double-sided adhesive tape without a substrate material, which is a special substrate-free double-sided adhesive with optical transparency.

[0003] Patent CN212170581U discloses a slitting device for an OCA optical adhesive die-cutting machine.

A transmission rod is inserted into the output shaft of the motor. This slitting device for the OCA optical adhesive die-cutting machine, by setting up a base, support column, support plate, hydraulic telescopic rod, sliding hole, transmission rod, fixed cylinder, fixed ring, slot, locking block, cutting blade, circular groove, convex column, and limiting ring, facilitates the activation of the hydraulic telescopic rod, causing it to drive the transmission rod and fixed cylinder to move up and down. The fixed cylinder, through the fixed ring, fixes the cutting blade downwards, cutting and slitting the optical adhesive, thereby enabling the OCA optical adhesive die-cutting machine to easily slit the OCA optical adhesive.

[0004] However, in actual use, the equipment has certain limitations. When it is necessary to cut OCA optical adhesive of different widths, the spacing of the fixing rings must be adjusted one by one. Due to the small spacing between the fixing rings, the adjustment process is not only cumbersome but also time-consuming, which significantly reduces the production efficiency of OCA optical adhesive molds.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0023] Reference Figures 1-3 As shown, this utility model embodiment provides a slitting device on an OCA optical adhesive die-cutting machine, including a frame 1. A first motor 22 is fixedly connected to the left end of the frame 1. A rotating shaft 2 is rotatably connected inside the frame 1. The output shaft end of the first motor 22 is fixedly connected to the left end of the rotating shaft 2. Cutting mechanisms 3 are equidistantly arranged on the side wall of the rotating shaft 2. A spacing adjustment mechanism 4 is provided at the upper end of the frame 1. The spacing adjustment mechanism 4 is used to adjust the spacing between the cutting mechanisms 3. A cutting auxiliary mechanism 5 is also provided inside the frame 1. The cutting auxiliary mechanism 5 cooperates with the cutting mechanisms 3 to perform cutting operations on the OCA optical adhesive. During operation, the rotating shaft 2 is driven to rotate by the first motor 22, which drives the cutting mechanisms 3 to move, realizing continuous cutting of the OCA optical adhesive. At the same time, the spacing adjustment mechanism 4 can quickly adjust the spacing between the cutting mechanisms 3 according to the required cutting strip width, without the need for individual adjustment, which greatly improves the adjustment efficiency and cutting accuracy. The cutting auxiliary mechanism 5 provides stable support for cutting, avoiding wrinkles or displacement of the optical adhesive during the cutting process, ensuring cutting quality, thereby achieving efficient and accurate OCA optical adhesive slitting operation.

[0024] In a further embodiment, refer to Figure 2 The cutting mechanism 3 includes a sleeve 31 and a cutting blade 32. The sleeve 31 is slidably connected to the side wall of the rotating shaft 2, and the cutting blade 32 is fixedly connected to the outer wall of the right side of the sleeve 31. A limiting block 311 is fixedly connected to the inner wall of the sleeve 31. A second limiting groove 21 is provided on the side wall of the rotating shaft 2, and the limiting block 311 is located inside the second limiting groove 21 and is slidably connected to it.

[0025] In this embodiment, by designing the cutting mechanism 3 as a combination structure of sleeve 31 and cutting blade 32, and by utilizing the sliding cooperation between the limiting block 311 and the second limiting groove 21, the rotation of the rotating shaft 2 can drive the sleeve 31 to rotate, thereby driving the cutting blade 32 to rotate. This ensures the stability of the cutting blade 32 during the cutting process, and also facilitates the quick adjustment of the position of the cutting blade 32 according to actual needs, thereby realizing the slitting operation of OCA optical adhesive of different widths.

[0026] In a further embodiment, refer to Figures 2-3The spacing adjustment mechanism 4 includes a connecting ring 41 and an extension block 43. The connecting ring 41 is rotatably connected to the outer left wall of the sleeve 31. A connecting rod 42 is fixedly connected to the upper end of the connecting ring 41. The extension block 43 is fixedly connected to the upper end of the connecting rod 42. A horizontal plate 12 is fixedly connected to the upper end of the frame 1. A first limiting groove 13 is opened on the upper surface of the horizontal plate 12. The upper end of the connecting rod 42 passes through the first limiting groove 13 and is slidably connected thereto. Threaded rods 46 are rotatably connected to the upper ends of the left and right sides of the frame 1 through bearing seats. The side walls of the threaded rods 46... A threaded sleeve 45 is connected by a thread, and a drive plate 44 is fixedly connected between the lower ends of the threaded sleeve 45. Multiple third limiting grooves 441 are opened on the upper surface of the drive plate 44. An extension block 43 is located inside the third limiting groove 441 and is slidably connected to it. The rear ends of two threaded rods 46 are connected by a sprocket assembly 47. A second motor 48 is fixedly connected to the upper left side of the frame 1. The output shaft end of the second motor 48 is fixedly connected to the front end of the threaded rod 46. The distance between adjacent third limiting grooves 441 gradually increases from front to back.

[0027] In this embodiment, the spacing adjustment mechanism 4 enables rapid and precise adjustment of the spacing of the cutting mechanism 3. Specifically, the rotational connection between the connecting ring 41 and the sleeve 31, as well as the structural cooperation between the connecting rod 42 and the extension block 43, allows the cutting mechanism 3 to move flexibly in the horizontal direction. The first limiting groove 13 on the horizontal plate 12 provides a stable guiding path for the sliding of the connecting rod 42, ensuring the smoothness of the adjustment process. When the second motor 48 is started to drive the threaded rod 46 to rotate, the threaded rods 46 are connected by a sprocket assembly 47, thereby driving both threaded rods 46 to rotate simultaneously. The rotation of the threaded rods 46 drives the threaded sleeve 45 to move, and the movement of the threaded sleeve 45 drives the drive plate 44 to move forward. As the drive plate 44 moves forward, the extension block 43 is located inside the third limiting groove 441 and is slidably connected to it, thereby driving the extension block 43 to move, causing the spacing between the extension blocks 43 to gradually increase, thereby adjusting the spacing between the cutting blades 32 in the cutting mechanism 3. This design of the spacing adjustment mechanism 4 not only simplifies the adjustment operation but also significantly improves the production efficiency and cutting accuracy of the OCA optical glue die-cutting machine.

[0028] In a further embodiment, refer to Figure 3 The cutting auxiliary mechanism 5 includes a connecting block 51 and an electric telescopic rod 52. Mounting holes 11 are provided on both the left and right ends of the frame 1. A pair of connecting blocks 51 are provided and slidably connected inside the mounting holes 11. A roller 53 is rotatably connected between the two connecting blocks 51. The roller 53 is located directly below the cutting blade 32. A pair of electric telescopic rods 52 are provided and fixedly connected to the left and right ends of the frame 1. The output shaft end of the electric telescopic rod 52 is fixedly connected to the lower end of the connecting block 51.

[0029] In this embodiment, the cutting auxiliary mechanism 5 provides important support and assistance for the cutting process of OCA optical adhesive. Through the extension and retraction of the electric telescopic rod 52, the connecting block 51 can be driven to slide up and down in the mounting hole 11, thereby driving the roller 53 to move vertically. The roller 53 is located directly below the cutting blade 32, which can provide stable support for the OCA optical adhesive during the cutting process, avoiding wrinkles, displacement or damage to the optical adhesive during cutting, thereby ensuring the stability and consistency of cutting quality. In addition, the position of the roller 53 can be flexibly adjusted according to the thickness of the optical adhesive and the cutting requirements, further improving the adaptability of the equipment and the cutting effect.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
