[0002] In the semiconductor integrated circuit manufacturing process, one of the steps is to stick a film on the surface or back of the wafer. In order to facilitate the turnover and storage of the wafer after film sticking, ring-shaped parts are often used to implement wafer film sticking. The film sticking method is: first stick the film on the ring-shaped part, and then attach the wafer to the tight film.

[0003] There is usually a layer of single-sided adhesive on the film. Before the ring-shaped part is attached to the film, the single-sided adhesive needs to be torn off.

The third forward and backward electric slide 510 is fixedly arranged on the frame 1 along the front-to-back direction and is located on one side of the first conveyor line 5, and the guide rail 520 is fixedly arranged on the frame 1 along the front-to-back direction and is located on the other side of the first conveyor line 5. The connecting plate 530 is erected between the third forward and backward moving electric slide 510 and the guide rail 520 along the left and right direction. The bottom of one end of the connecting plate 530 is fixedly connected to the slide seat of the third forward and backward moving electric slide 510, and the bottom of the other end of the connecting plate 530 is fixedly connected to the slider on the guide rail 520. The first bearing seat 550 is fixedly arranged on the slide seat of the third forward and backward moving electric slide 510, and the second bearing seat 560 is fixedly arranged on the slider of the guide rail 520. One end of the rubber roller 500 is rotatably connected to the first bearing seat 550 through a bearing, and the other end of the rubber roller 500 is rotatably connected to the second bearing seat 560 through a bearing. The rubber roller driving motor 540 is fixedly arranged on the slider of the guide rail 520 and is used to drive the driving pulley 570 to rotate. The driven pulley 580 is connected to one end of the rubber roller 500, and the transmission belt 590 is wound around the driving pulley 570 and the driven pulley 580.

[0035] During the glue peeling process, in the first step, the second left-right transfer electric slide 410, the second front-back transfer electric slide 420 and the third lifting electric slide 430 cooperate with each other to drive the glue peeling cylinder 440 to reach a corner of the glue film; in the second step, the glue peeling cylinder 440 drives the glue peeling clamp 450 to clamp a corner of the single-sided glue on the surface of the glue film (the surface of the glue film is provided with a single-sided glue. In order to facilitate glue peeling, a corner of the single-sided glue is usually not provided with a glue coating to avoid adhesion to the glue film); in the third step, the second left-right transfer electric slide 410, the second front-back transfer electric slide 420 and the third lifting electric slide 430 cooperate with each other to drive the glue peeling cylinder 440 to reach a corner of the glue film; in the second step, the glue peeling cylinder 440 drives the glue peeling clamp 450 to clamp a corner of the single-sided glue on the surface of the glue film (the surface of the glue film is provided with a single-sided glue. In order to facilitate glue peeling, a glue coating is usually not provided at one corner of the single-sided glue to avoid adhesion to the glue film); The transfer electric slide 420 and the third lifting electric slide 430 cooperate with each other to drive one corner of the single-sided adhesive to move toward its own diagonal direction; at the same time, the rubber roller driving motor 540 drives the rubber roller 500 to rotate through the active pulley 570, the transmission belt 590 and the driven pulley 580 in sequence, and the third front and rear transfer electric slide 510 drives the rotating rubber roller 500 to press against the single-sided adhesive and the adhesive film, so as to utilize the tangential friction force generated between the rubber roller 500 and the single-sided adhesive to assist the single-sided adhesive to separate from the adhesive film.

[0036] It should be noted that the transverse glue tearing mechanism 7 tears the single-sided glue along the diagonal direction of the glue film, and the tangential glue rolling mechanism 8 assists in glue tearing along the length direction of the glue film. This method can increase the degumming speed of the single-sided glue in the length direction, thereby accelerating the glue tearing efficiency. In addition, the rubber roller 500 is configured to rotate in the direction opposite to the moving direction. As in the present application, the third front and rear transfer electric slide 510 drives the rubber roller 500 to move from back to front to contact between the single-sided glue and the glue film, and the rubber roller drive motor 540 drives the rubber roller 500 to rotate in a backward rolling posture (clockwise). This driving method is the key to achieving auxiliary glue tearing.

The telescopic end of the pressure-maintaining electric cylinder 640 is connected to the movable plate 630 through a pressure sensor 650. The pressure-maintaining plate 660 is fixed on the bottom side of the movable plate 630 and is arranged corresponding to the pressure-maintaining station up and down.

The bottom side of the pressure-maintaining plate 660 is provided with a plurality of heat-conducting holes connected to the installation cavity, and a temperature sensor is arranged in the pressure-maintaining plate 660.

[0038] During the pressure holding process, in the first step, the pressure holding electric cylinder 640 drives the pressure holding plate 660 to press down on the film with the ring-shaped member to achieve pressure holding; in the second step, the heater 670 works and the temperature is transferred to the film through the heat conduction hole. At the same time, the pressure sensor 650 monitors the pressure holding pressure in real time, and the temperature sensor monitors the pressure holding temperature in real time to ensure product consistency.

Among them, the third left and right transfer electric slide 710 is fixed on the frame 1 and is used to drive the lifting cylinder 720 to move left and right, the lifting cylinder 720 is used to drive the adsorption frame 730 to move up and down, and a plurality of vacuum suction nozzles 740 are fixed on the bottom side of the adsorption frame 730 and are used to adsorb adhesive films or ring-shaped parts. It should be noted that the vacuum suction nozzle 740 is connected to an external negative pressure generating device to achieve material "grabbing".

[0040] Taking the handling of adhesive film as an example, in the first step, the third left and right transfer electric slide 710 first drives the lifting cylinder 720 to move to the top of the adhesive film feeding mechanism 2; in the second step, the lifting cylinder 720 drives the adsorption frame 730 to move downward, and makes the vacuum suction nozzle 740 contact with the upper surface of the adhesive film; in the third step, the negative pressure generating device works, the vacuum suction nozzle 740 generates negative pressure and adsorbs and fixes the adhesive film; in the fourth step, the lifting cylinder 720 drives the adsorption frame 730 to move upward, so that the adhesive film leaves the adhesive film feeding mechanism 2; in the fifth step, the third left and right transfer electric slide 710 drives the lifting cylinder 720 to move to the top of the adhesive tearing station; in the sixth step, the lifting cylinder 720 drives the adsorption frame 730 to move downward to the adhesive tearing station; in the seventh step, the negative pressure generating device controls the vacuum suction nozzle 740 to release the pressure to release the adhesive film; this is repeated to realize the cyclic loading of the adhesive film. It should be noted that in the third step, the negative pressure generating device works, and after the vacuum nozzle 740 generates negative pressure and fixes the film by adsorbing it, the first limiting cylinder 250 and the second limiting cylinder 260 in the film feeding mechanism 2 are reset to avoid interference.

[0041] It should be noted that the third left and right transfer electric slide 710 in the loading and handling mechanism 10 and the second left and right transfer electric slide 410 in the horizontal glue tearing mechanism 7 have the problem of limited installation space during the actual installation process, so a double-screw electric slide can be used to replace the two.

[0042] Therefore, the present invention has the following advantages:

[0043] The present invention proposes a fully automatic ring-shaped film laminating machine, which assists in tearing off the single-sided adhesive by setting up a tangential glue rolling mechanism and utilizing the tangential friction force generated between the rubber roller and the single-sided adhesive when the rubber roller rotates. Compared with the transmission glue tearing method, the glue tearing speed of this scheme is greatly improved, thereby greatly improving the working efficiency of the ring-shaped film laminating machine, and is suitable for popularization and use.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
