Description

Vacuum tear film recycling mechanism

The present invention is a vacuum tear film recovery mechanism, especially a mechanism that uses vacuum suction to tear off and recover the film on the substrate.

By the way, most of the current tearing process uses tape tearing methods. Please refer to Figure 1. A working platform 11 is provided on the working platform 11 with a conveyor belt 12 for removing the substrate 13 to be teared from the The front end of the work platform 11 is transported to the rear end of the work platform 11. A side of the front end adjacent to the work platform 11 is provided with a substrate placement box 14 for tearing the film, and a gripping mechanical arm (not shown) can be used, The substrate 13 to be torn from the substrate placement box 14 is taken out and placed on the front end of the work platform 11, so that the substrate 13 to be torn is transported by the conveyor belt 12, and the work platform 11 The front end is transported to the rear end of the work platform 11. A substrate collection box 15 is provided on one side adjacent to the rear end of the work platform 11, and an inserting mechanical arm (not shown in the figure) can be used to make the back end of the work platform 11 The substrate 131 with the film to be peeled off is clamped and inserted into the clip 151 of the substrate collecting box 15.

The working platform 11 is provided with a set of pressing wheels 16 near the center, a working wheel 17 is arranged above one side of the adjacent group of pressing wheels 16, and a recovery wheel 18 is arranged above the other side corresponding to the working wheel 17. The working wheel 17 is provided with an adhesive tape 19 so that the adhesive tape 19 spans between the three rollers (the set of pressing wheels 16, the working wheel 17, and the recovery wheel 18), and the adhesive tape 19 is provided with glue on the outward side. Thereby, when the substrate 13 to be torn off passes the set of laminating wheels 16, the adhesive force of the adhesive tape 19 is used to peel off the film 132 of the substrate 131, so that the material of the film 132 is rolled into the recycling wheel along with the tape 19 The recycled film of 18 completes the peeling action of the film 132, but the disadvantage of this method is that the torn-off film 132 is difficult to recycle, and it is easy to leave glue on the film 132.

Therefore, the current tearing process for film recycling is mainly a manual squeegee method. Please refer to Figure 2. The substrate 13 to be teared is placed on a stage 21, and a squeegee 22 is used to apply stress to the film. 132 is separated from the substrate 131, and the separated film 132 is manually torn off. However, the use of the scraper 22 to apply stress is likely to cause damage to the film 132, resulting in a lower production yield.

Therefore, in the above-mentioned conventional technology, after the film 132 is formed on the substrate 131, the process of completely tearing off the film 132 still needs to be developed and improved to meet the requirements of recyclability, no damage and no glue residue.

In view of this, the inventor of this case has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above-mentioned goals, after detailed design and careful evaluation, he finally obtained a practical invention.

The object of the present invention is to provide a vacuum tearing film recycling mechanism, which uses vacuum suction to tear off and recover the film on the substrate, so as to meet the requirements of film recyclability, no damage and no glue residue.

According to the above objective, the vacuum tear film recovery mechanism of the present invention mainly includes: a conveyor belt, a pressing wheel, a working wheel, a recovery wheel, and an elastic belt; wherein the conveyor belt will be The tear film substrate is transported from the front end of the conveyor belt to the rear end of the conveyor belt; the pressing wheel is pressed against the near center of the conveyor belt, and is connected with a power source to rotate; the working wheel is arranged adjacent The upper side of the pressing wheel is connected with a power source and can rotate; the recovery wheel is arranged above the other side of the adjacent pressing wheel, and is connected with a power source and can rotate; the elasticity The belt is sleeved on the pressing wheel, the working wheel, and the recovery wheel so that it spans between the pressing wheel, the working wheel and the recovery wheel. The elastic belt is provided with a multi-port suction cup micro The structure is used to evenly distribute the vacuum suction force and generate the vacuum adhesion of Van der Waals force. The pressing wheel, the working wheel, and the recovery wheel can drive the elastic belt to rotate synchronously when rotating ; With this, when the substrate to be torn film passes the pressing wheel, the multi-mouth suction cup microstructure of the elastic belt will be pressed down on the film of the substrate to be torn film, so that the air in the substrate is discharged to form a vacuum, The film generates vacuum suction, and then the relative movement of the elastic band and the substrate separates the film of the substrate to be torn from the substrate; in this way, the film on the substrate is torn off by the vacuum suction, so that the film is recyclable and not damaged With no residual glue requirements.
