DETAILED DESCRIPTION

[0023] 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.

[0024] Example: Figures 1-5 As shown, this utility model provides an OCA optical adhesive cutting device with anti-sticking function, including a worktable 1, a cutting groove 101 on the top of the worktable 1, a cutter 2 on the top of the worktable 1, a control component 3 on the back of the cutter 2, the cutter 2 is fixed to the worktable 1 through the control component 3, and the cutter 2 can enter the cutting groove 101 to complete the cutting.

[0025] Furthermore, a mounting platform 309 is fixedly connected to the top of the support base 301. A telescopic cylinder 310 is installed in the middle of the mounting platform 309. A guide cylinder 311 is fixedly connected to the output end of the telescopic cylinder 310. A guide roller 313 is built into the guide cylinder 311. The guide roller 313 is slidably connected to the inner wall of the guide cylinder 311. A telescopic spring 312 is built into the guide cylinder 311. One end of the telescopic spring 312 contacts the guide roller 313, and the other end of the telescopic spring 312 contacts the bottom of the inner cavity of the guide cylinder 311. Limiting windows 314 are opened on both sides of the guide cylinder 311. Limiting rods 315 are built into the limiting windows 314. The limiting rods 315 are slidably connected to the inner wall of the limiting windows 314. One end of the limiting rods 315 is fixedly connected to the guide roller 313. When the cutting device is started, the telescopic cylinder 310 starts to work, and its output end pushes the guide cylinder 311 to move downward. Since the guide roller 313 is slidably connected to the inner wall of the guide cylinder 311 and is acted upon by the telescopic spring 312, in the initial stage, the cutter 2 cannot immediately move down due to the limit of the trigger seat 201. At this time, the telescopic spring 312 is compressed, and the cutter 2 begins to accumulate force.

[0026] Furthermore, the control component 3 includes two support seats 301. The bottom of each support seat 301 is fixedly connected to both sides of the worktable 1. The two support seats 301 are symmetrically distributed along the axis of the worktable 1. Mounting grooves 302 are formed on the end faces of the two support seats 301 that are close to each other. Fixed cylinders 303 are fixedly connected to both sides of the inner wall of the mounting grooves 302. Embedding grooves 308 are formed on both sides of the mounting grooves 302. A rotating roller 304 is housed inside the fixed cylinder 303. Both ends of the rotating roller 304 are rotatably connected to the bottom of the inner cavity of the fixed cylinder 303. Coil springs 305 are sleeved on both ends of the rotating roller 304. The coil springs 305 are placed inside the fixed cylinder 303. One end of the coil spring 305 is fixedly connected to the inner wall of the fixed cylinder 303, and the other end of the coil spring 305 is connected to the surface of the rotating roller 304. The rotating roller 304 is fixedly connected to the surface. A toggle seat 306 is sleeved in the middle of the rotating roller 304. A scraper 307 is fixedly connected to the top of the toggle seat 306 away from the rotating roller 304. Trigger seats 201 for cooperating with the toggle seat 306 are fixedly connected to both sides of the cutter 2. The end of the trigger seat 201 away from the cutter 2 has an elliptical surface 202 structure. The trigger seat 201 is slidably connected to the scraper 307 and the toggle seat 306. As the guide cylinder 311 continues to move down, when the accumulated force is sufficient to overcome the elastic force of the coil spring 305, the interaction between the trigger seat 201 and the toggle seat 306 allows the cutter 2 to release the force of the telescopic spring 312. The cutter 2 suddenly moves down and quickly cuts into the OCA optical adhesive placed on the worktable 1 and corresponding to the cutting groove 101, completing the cutting action. During the downward movement of the cutter 2, the trigger seats 201 on both sides of the cutter 2 will slide along the scraper 307 of the actuating seat 306 and the actuating seat 306 itself. The relative movement between the elliptical surface 202 structure of the trigger seat 201 and the scraper 307 and the actuating seat 306 causes the rotating roller 304 to rotate. The coil springs 305 at both ends of the rotating roller 304 are twisted to store energy. After the cutting is completed, the telescopic cylinder 310 drives the guide cylinder 311 to move upward back to its original position. At this time, the rotating roller 304 rotates in the opposite direction under the restoring force of the coil spring 305. Its surface generates relative friction and rolling with the side of the cutter 2, scraping off the OCA optical adhesive that may stick to both sides of the cutter 2 during the cutting process, thus achieving the anti-sticking function.

[0027] Through the design of special trigger seat 201, toggle seat 306, rotating roller 304, and coil spring 305, the cutter 2 can move down quickly during cutting, reducing the chance of OCA optical adhesive sticking to the cutter 2 by utilizing speed advantage. After cutting, it can automatically perform anti-sticking treatment, effectively improving cutting efficiency and quality, reducing cutting interruptions caused by sticking and subsequent cleaning and maintenance time, and improving the continuity of overall production. By using the cooperation of telescopic spring 312 and trigger seat 201, force is accumulated before cutting, and released when a certain level is reached to cut, which can better control the cutting force of the cutter 2 into the OCA optical adhesive, avoiding cutting defects caused by excessive or insufficient cutting force, such as uneven cuts, material damage, or incomplete cutting, thus improving cutting accuracy and product qualification rate.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
