In the prior art, when OCA optical cement is cut, the cutter moves from top to bottom to cut the OCA optical cement, and in the process that the cutter contacts the OCA optical cement and cuts down, the cutter can produce extrusion effect on the OCA optical cement, so that obvious glue overflow phenomenon can occur at a notch.
Therefore, in this embodiment, under the guidance of the guide track 7, the cutting assembly 3 is driven by the traversing mechanism 1 to move from one side to the other side along the width direction of the OCA optical adhesive, so as to cut from the side surface of the OCA optical adhesive, thereby alleviating the extrusion effect on the OCA optical adhesive formed in the cutting process, and remarkably reducing the glue overflow phenomenon during cutting.
In this embodiment, as shown in fig. 1 and 2, the traversing mechanism 1 is erected on the cutting platform 8, two ends of the traversing mechanism 1 are raised by the support 2, and conventionally, the traversing mechanism 1 is a linear guide rail motion mechanism, which generally includes, but is not limited to, a guide rail, a slide block, a transmission mechanism, a motor, etc., and the motor is utilized to convert the rotation motion into the linear motion of the slide block along the guide rail by the transmission mechanism, and the transmission mechanism can be driven by a ball screw, a rack and pinion or a synchronous belt, so that the detailed description of the linear guide rail motion mechanism is omitted.

Thus, it is easily conceivable that when the cutting assembly 3 moves along the guide rail 7, since the guide rail 7 presents rail surfaces having different heights, the cutting assembly 3 has a lifting movement, so that it moves down to a low rail surface and moves laterally to cut OCA optical cement, and moves up to a high rail surface and moves laterally, and the cutting assembly 3 withdraws from cutting. In the technical scheme, compared with the traditional top-down cutting mode, the transverse cutting mode is adopted, the pressure effect on the OCA optical adhesive is obviously smaller, and therefore the adhesive overflow phenomenon can be obviously reduced.
In one embodiment, as shown in fig. 3 and 4, the cutting assembly 3 includes a spreader, a cutting motor 306 and a cutting blade 307, the spreader is assembled on the traversing mechanism 1, the specific spreader is fixed on a fitting slider of the linear guide moving mechanism, the spreader moves along with the slider, the cutting motor 306 is fixedly mounted on the spreader, moves along with the slider along with the spreader, the cutting blade 307 is assembled at an output end of the cutting motor 306, and the cutting blade 307 is driven by rotation of the cutting motor 306 to complete cutting of the OCA optical cement.
It is conceivable that, in this embodiment, by fixing the spreader to the traversing mechanism 1, the cutting motor 306 is mounted on the spreader, and the cutting blade 307 is driven to rotate by the cutting motor 306, so that the rotating cutting blade 307 moves from one side to the other side along the width direction of the OCA optical cement to cut, the cutting motor 306 stops rotating after cutting, and the traversing mechanism 1 returns the original path of the cutting assembly 3 to the side of the initial position to wait for the next cutting.

And, four ear hanging platform 302 has four lugs, and every lug is provided with the slip cap hole along vertically lining up, and every lug passes through the slip cap hole slip cover and is on guide bar 304, and the top of four ear hanging platform 302 remains hugging closely with guide rail 7, and the hoist is along with the in-process that sideslip mechanism 1 removed, and four ear hanging platform 302 receives guide rail 7 downward pressure effect all the time to make four ear hanging platform 302 remain the extrusion to first spring 305, because first spring 305 is in the pressurized state all the time, so the hoist is in the messenger of following guide rail 7 removal, and first spring 305 provides the reaction force, can realize hoist from low to high elevating movement. Meanwhile, a motor mounting bracket 303 is welded on the top of the four-lug hanging platform 302, the motor mounting bracket 303 is provided with a cavity for fixing a cutting motor 306, and the cutting motor 306 is mounted in the cavity through screws.

In a preferred embodiment, as shown in fig. 3, 4 and 6, the cutting assembly 3 is further provided with a scraping assembly 4, and the scraping assembly 4 is used for scraping the adhesive remained on the cutting blade 307. Specifically, the doctor assembly 4 includes a doctor blade holder 401 and a doctor blade 402, wherein, as shown in fig. 6, the doctor blade holder 401 is welded on the motor mounting frame 303 through an L-shaped structure, the doctor blade holder 401 is disposed obliquely downward, a U-shaped cavity is disposed on a side of the doctor blade holder 401 facing the cutting blade 307, and the U-shaped cavity semi-surrounds the cutting blade 307.

The end of the doctor blade holder 401 remote from the cutting blade 307 is provided with a glue outlet 403, and the glue outlet 403 is provided with a shutter 404 that can be opened upward.
It can be appreciated that, due to the glue overflow phenomenon of different degrees during cutting, the cutting blade 307 may adhere to the adhesive, the adhesive forms a glue block after cooling, and the repeated cutting of the cutting blade 307 with the glue block can cause the glue block remained on the cutting blade 307 to be scraped to the OCA optical adhesive during the use process, thereby affecting the cleaning degree of the OCA optical adhesive.
Therefore, in this embodiment, the doctor blade 402 is attached to the cutting blade 307 by installing the doctor blade 402 on the side of the cutting blade 307, so that the doctor blade 402 contacts the doctor blade 402 during rotation of the cutting blade 307, and then the glue piece attached to the surface of the doctor blade is scraped into the doctor blade 401 by the doctor blade 402.

Based on the above, the working process of the OCA optical cement cutting device provided by the embodiment of the application is as follows:
firstly, conveying OCA optical cement to a cutting platform 8 by a feeding mechanism 9, and suspending the feeding mechanism 9 after the OCA optical cement is conveyed to a preset cutting length;
Then, the traversing mechanism 1 carries the cutting assembly 3 to move along the guide track 7, the cutting assembly 3 gradually moves from high to low to the lowest point, the upper panel 802 is pressed down to be attached to the OCA optical adhesive, the negative pressure pump 806 is started to generate negative pressure to adsorb the OCA optical adhesive, the OCA optical adhesive is cut along with the transverse movement of the cutting mechanism on the lowest track surface, the UV curing assembly 6 rapidly cures the adhesive on the cutting blade 307 along with the rotation of the cutting blade 307 during the cutting, and the adhesive block cured on the surface of the cutting blade 307 is scraped by the adhesive scraping assembly 4;
Then, after the cutting assembly 3 completes cutting, gradually moving from low to high to the highest point, and continuously moving to the outer side of the cutting platform 8, the second magnetic attraction piece 5 generates attraction force on the first magnetic attraction piece 405, lifts the baffle 404, and starts the glue discharging opening 403 to discharge glue;
finally, the cutting blade 307 is stopped, the cutting assembly 3 returns to the initial position along the guide rail 7, and the cut OCA optical cement is sent away by the feeding mechanism 9 to perform the next round of cutting.
It can be appreciated that the position cut length of the OCA optical cement can be determined by the feeding speed and feeding time of the feeding mechanism.
The foregoing description of the preferred embodiments of the application is not intended to limit the application to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the application are intended to be included within the scope of the application.
