detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Film tearing mechanism of the present invention comprises film tearing head and is used for supplying adhesive tape and the adhesive tape supply device of recovery tape to film tearing head, and described tape supply device comprises frame 5, glue releasing mechanism, glue collecting mechanism and tape tensioning mechanism, The frame 5 is connected with the film tearing head, and the glue releasing mechanism, the glue collecting mechanism and the tape tensioning mechanism are installed on the frame 5 respectively, and the film tearing head includes a tape supply for the glued surface of the tape towards the outside. The part of the mucous membrane that is in contact with the membrane.

The main principle of the present invention is to supply adhesive tape to the film tearing head through the tape supply device, contact the tape on the film tearing head with the film, adhere the tape, and then promote the separation of the film and the glass substrate through the adhesive effect of the tape, and finally use Used tape and film recycling.

There are multiple implementations of the film tearing head and the adhesive tape supply device. For example, the film tearing head includes an opening, and the adhesive surface of the adhesive tape at the opening is facing the outside, that is, towards the glass substrate, the opening of the film tearing head can be provided with a pressure head for supporting the adhesive tape, and the adhesive tape supply device can make the adhesive tape pass through the above opening At the position, the glass substrate can be driven by the corresponding lifting mechanism to make the film on the surface of the glass substrate adhere to the tape at the opening, and then separate the film from the glass substrate as the tape runs.

The invention provides the embodiment of the film tearing head. As shown in Figure 1, the tearing film head includes a support frame 3, and the mucous membrane portion of the film tearing head includes a mucous membrane roller 15, a lead-in roller 6 and a lead-out roller 4 that are arranged on the support frame from bottom to top in sequence, and the lead-in roller 4 is located at Between the adhesive film roller 15 and the lead-in roller 6, wherein the adhesive film roller 15 is used to have the glued side of the adhesive tape towards the film, the lead-in roller 6 is used to import the adhesive tape to the adhesive film roller 15, and the export roller 4 is used to guide the adhesive tape to the film. The tape is led out in a state away from the lead-in roller. When this film tearing head is used, because it adopts the form of the adhesive film roller 15, the contact area with the film is small, and it can accurately contact the designated position of the film, such as the top angle of the film. The reason for precise contact is that the top corners of the film are the easiest to tear, that is, the easiest place to separate the film from the glass substrate. It is relatively easy to tear the film from this position, and the load of the required related equipment is also small, and it is not easy to cause unnecessary damage to the glass substrate. As can be seen in conjunction with Fig. 1, the adhesive surface of the adhesive tape is in contact with the lead-in roller 6, and the non-adhesive surface of the adhesive tape is in contact with the lead-out roller 4, so that when the adhesive tape passes through the adhesive film roller 15, the adhesive surface is facing outward, that is, towards the The film is torn off so that the tape can be attached to the film. And film can be exported by the outside of leading-out roller 4 along with adhesive tape once being torn off. Arranging the adhesive film roller 15, the lead-in roller 6 and the lead-out roller 4 according to the above-mentioned layout mode is also beneficial to avoid interference between the sections of adhesive tape. When setting, in combination with Fig. 1 and Fig. 2, a tension roller can be arranged obliquely above the lead-out roller 4, and then the adhesive tape can be recovered on the glue-receiving roller 12 through a plurality of sticks, and the route of the tape export is far away from the above-mentioned lead-in roller 6. Simultaneously, the relevant stick that cooperates with lead-in roller 6 and glue roller 13 can be arranged on the side close to lead-in roller 6, so just can not interfere with the lead-out route of adhesive tape.

In actual use, only a section of the adhesive film roller 15 needs to be in contact with the film, and the entire area along the axial direction does not need to be in contact with the film. In this case, there is no need for the entire body of the sticky film roll 15 to be wrapped with adhesive tape, only a section of wrapped adhesive tape is required. This saves the amount of tape used. But sometimes the tape may run off, and if the tape is too narrow, plus the run off, it may not be in contact with the membrane. In order to not only save the tape, but also ensure that the tape can be in contact with the film, on the basis of the above, the introduction roller 6 is provided with a limit groove 7 for preventing the tape from running off. The width of this limiting groove 7 is exactly the width of adhesive tape, and adhesive tape enters adhesive film roller 15 by limiting groove 7 then, owing to limiting groove 7, makes adhesive tape be positioned at the fixed position on adhesive film roller 15, when in use, can above-mentioned position Align the corresponding corners of the film so that the adhesive tape on the sticky film roller 15 is just in contact with the corresponding corners of the film, so that the film can be torn off accurately.

Because in the process of tearing the film, the tearing film head can move through the corresponding mechanism, such as pressing down, rising, moving back and forth, etc. It is also possible that the film tearing head does not move, and the glass substrate moves through a corresponding mechanism. For example, the frame 5 of the adhesive tape supply device is also equipped with an up and down feeding mechanism 2 for driving the tearing head to move linearly in the vertical direction. When in use, the film tearing head is pressed down by the up and down feeding mechanism 2 to make the adhesive tape contact with the film, and then the glass substrate is moved horizontally through the corresponding mechanism to separate the film from the glass substrate.

For another example, the frame 5 of the adhesive tape supply device is connected with a forward and backward feeding mechanism 10 for driving the frame 5 to move linearly along the horizontal direction. In this case, the glass substrate is raised by the corresponding mechanism to contact the adhesive tape of the tearing head, and then the frame 5 is moved by the front and rear feeding mechanism 10, the tearing head will move together, and the movement of the tearing head will drive the adhesive tape The film was torn off and separated from the glass substrate.

Another embodiment is as follows: the frame 5 of the adhesive tape supply device is also equipped with an up and down feed mechanism 2 for driving the tearing film head to move linearly in the vertical direction, and the frame 5 of the adhesive tape supply device is connected to the The front and rear feeding mechanisms 10 that drive the frame to move linearly in the horizontal direction are connected, and the moving direction of the front and rear feeding mechanisms 10 is perpendicular to the moving direction of the up and down feeding mechanism 2 . The above method can make the film tearing head move up and down and move back and forth with the frame. The moving directions of the above-mentioned up-and-down feeding mechanism 2 and the forward-backward feeding mechanism 10 can refer to the arrows in FIG. 1 . When in use, the adhesive tape is supplied to the film tearing head through the tape supply device, the film tearing head is moved to the top of the glass substrate through the front and rear feeding mechanism, and the adhesive surface of the tape on the film tearing head is pressed against the surface of the glass substrate through the up and down feeding mechanism Then, the frame moves away from the glass substrate through the forward and backward feeding mechanism. During the movement of the frame to the direction away from the glass substrate, the adhesive tape with the film is recovered by the tape supply device. The above approach reduces relative movement of the glass substrate. Effectively protect the glass substrate from damage. In order to separate the film from the glass substrate more easily, when the above structure is adopted, when the frame moves away from the glass substrate, the film tearing head is gradually raised by the up and down feeding mechanism, and the adhesive tape is recovered by the glue collection mechanism. That is to imitate the lifting action of human hands when tearing the film. This allows easier and faster separation and recycling of the membrane from the glass substrate.

It has been mentioned above that the top corner of the film is the position that is easy to be torn, so when tearing the film, it is best to align the tape of the film tearing head with the corresponding top corner of the film. In order to achieve the above purpose, when placing the film tearing mechanism of the present invention, the relative angle between the film tearing head and the film can be adjusted, as shown in FIG. 1 for example. In Figure 1, there are 4 stations on the turntable 1, and the position of the film tearing mechanism and the film on each station is just enough to ensure that the film tearing head can extend to the top corner of the corresponding film. However, in reality, there will be glass substrates of different sizes, and the size of the film will be different at this time. At this time, it is necessary to adjust the position of the film tearing mechanism to match the film of different sizes. In order to achieve the above object, on the above basis, the front and rear feeding mechanism 10 is installed on the left and right feeding mechanism 11 that moves linearly in the horizontal direction, and the moving direction of the left and right feeding mechanism 11 is perpendicular to the moving direction of the front and rear feeding mechanism 10 . In this way, the film tearing mechanism can realize flexible movement in three-dimensional directions such as front and rear, left and right, and up and down. Therefore, the overall position of the film tearing mechanism can be adjusted conveniently to adapt to films of different sizes.

Since the film has adhesive force during the film tearing process, the film will also produce a reaction force on the tape during the process of tearing the film. If the film has low adhesion, it will not affect the tape. If the adhesive force of the film is large, in order to prevent the tape from loosening due to the dragging of the film during long-term use, thereby affecting the tearing efficiency, the following structure can be adopted. As shown in Figures 1 and 2, the glue releasing mechanism includes a glue releasing roller 13, the glue collecting mechanism includes a glue collecting roller 12 driven by a first motor, and the tensioning mechanism includes a pulling roller driven by a second motor. Rubber roller 9, a pressure roller 8 and a plurality of tension rollers for pressing the adhesive tape on the rubber roller 9, the rubber roller 9 cooperates with the pressure roller 8 to make the adhesive tape move towards the rubber collection roller 12 below . When above-mentioned pinch roller 8 is set, can refer to Fig. 1 and Fig. 2, by installing turret on frame 5, one end of turret is installed pinch roller 8, and pinch roller 8 increases its downward force by weight mechanism, thereby Make it can compress adhesive tape on dragging rubber roller 9. In the process of tearing the film, through the synergy of the first motor and the second motor, the tape can be recovered while tearing the film, so that the film can move with the tape, so that the film can be torn off more easily and quickly, and the tape’s For the direction, refer to the direction of the arrow in Figure 2. It is also very important at the same time, because the synergistic effect of dragging the rubber roller 9 and the pressure roller 8 can effectively ensure that the adhesive tape remains in tension during the film tearing process and will not loosen. This can ensure the long-term continuous and normal use of the film tearing mechanism.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above descriptions are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
