Description

The presently disclosed invention generally relates to a film lamination method and an apparatus for performing the same, and more particularly to a method for laminating a film on a substrate of a touch panel.

Advances in science and technology have led to the emergence of powerful, intelligent devices such as computers, PDAs, intelligent mobile phones or flat-panel computers. Many intelligent devices have a touch panel to allow the user to operate the devices by the touch method.

An important factor in the touch panel is glass, and therefore, before shipping these items (for example after cutting the glass with a laser or during the glass lamination process), staining of the glass surface due to scratches or foreign matter thereon is required. It is required to cover the glass film layer to prevent it. In addition, the cover film layer covered on the glass needs to prevent bubbles generated between the cover film and the glass after lamination.

Conventionally, during the manufacturing process of laminating films, workers use the naked eye to check whether the quality before and after laminating the glass meets the criteria (ie whether there are any foreign objects or bubbles). However, inspection methods by known persons use inconsistencies and relatively unobjective judgments due to factors such as different workers, different times, and length of overtime. This affects the stability and quality of the laminated film, thereby reducing the yield of the laminated film on the glass.

With reference to preferred embodiments, the implementation of the film laminating apparatus and the film laminating method is described. The film laminating apparatus may be implemented with a small film laminating apparatus or a large film laminating apparatus. For example, so-called small film lamination apparatuses are suitable for laminating films on 5 inch or less substrates; For example, a so-called large film lamination apparatus is suitable for laminating a film on a 5 to 15 inch substrate. The above-mentioned substrates include, but are not limited to, materials such as glass, plastic, and acryl.

1 to 4 respectively show a structural diagram, a side view, a rear view, and a top view according to the first embodiment of the film laminating apparatus disclosed herein. Also, the first embodiment is used to describe the small film lamination apparatus.

As shown in FIGS. 1 to 4, the film lamination apparatus 20 includes a lamination platform 22, a rolling mechanism 24, a loading platform 26, a suction tool 28, a position sensor 30, a light detector ( 32), and a programmable logic controller 34. Programmable logic controller 34 is used to control the operations of stacking platform 22, rolling mechanism 24, and suction tool 28.

Lamination platform 22 includes a rotating mechanism 23 and a plurality of conveying tools 36. This embodiment illustrates four conveying tools 36. The conveying tools 36 are disposed on the rotating mechanism 23 and used to convey the substrate 38. The programmable logic controller 34 controls the angle of the stacking platform 22 to control the angle at 90 ° each time so that the substrate 38 is transported separately by each transport tool 36 to be detected or stacked in turn. The rotating mechanism 23 is controlled.

The rolling mechanism 24 includes an import plate 40, at least one roller 42, and a recycling plate 44. The retraction plate 40 loads and rolls out the adhesive tape attached to the film (such as a release film) on the loading platform 26. The roller 42 is disposed below the feed plate 40 and is used to support and move the adhesive tape attached to the film. The tape may be recycled as the recycling plate 44 rolls off the peeled adhesive tape. Specifically, the programmable logic controller 34 controls the entry plate 40 to roll out the adhesive tape attached to the film and the adhesive tape is positioned at the position of the loading platform 26 through the roller 42 for rolling. The programmable logic controller 34 then controls the recycling plate 44 to recycle the peeled adhesive tape through the roller 42. When the programmable logic controller 34 expects the adhesive tapes loaded on the rolling mechanism 24 to be used, the programmable logic controller 34 notifies the workers to replace the adhesive tapes (such as warning sounds, flashes, etc.). Generate a notification message.

Programmable logic controller 34 controls the suction tool 28 to align with the loading platform 26 to suck and peel off the film from the adhesive tape. Next, the suction tool 28 is parallel with the conveying tool 36 to attach the film to the substrate 38.

In addition, the position sensor 30 is designed by this embodiment, which is used to detect the position of the film sucked by the suction tool 28. The programmable logic controller 34 may also control the suction tool 28 to perform the positioning procedure based on the sensing result of the position sensor 30. Therein, the position sensor 30 of the present embodiment includes a cavity stop switch and an optical fiber.

In addition, the photo detector 32 is designed with several optically coupled elements 46 (such as a charge-coupled device (CCD)). For example, the present photodetector 32 is designed with two optically coupled elements 46. The first optically coupled element 46 film lamination apparatus 20 may help to detect stains, scratches, or foreign objects on the surface of the substrate 38 disposed on the transport tool 36. There, the substrate 38 was not laminated with a film (hereinafter referred to as an uncoated substrate 38). On the other hand, the second optically coupled element 46 may help detect bubbles on the film 38 on which the film stacking device 20 is placed on the conveying tool 36. When detection of either of the two light coupling elements 46 is complete, the programmable logic controller 34 generates a notification message based on the detection results of the light detector 32. Therefore, the programmable logic controller 34 of the present embodiment can determine the state before and after laminating the film on the substrate 38 based on the detection result of the photo detector 32.

Based on the above-mentioned structure, the top view of FIG. 4 is located at 0 ° (top), 90 ° (right), 180 ° (lower), and 270 ° (left) positions of the rotary mechanism 23. Four conveying tools 36 are shown. Two optically coupled elements 46 are installed above the 0 ° and 180 ° positions. Therefore, assuming that the rotating mechanism 23 turns 90 degrees each time in the clockwise direction, the workers obtain the substrate 38 on which the film is laminated and the other uncoated substrate on the conveying tool 36 rotated to the 90 ° position. 38 can be positioned. Similarly, an optically coupled element 46 installed above the 180 ° position can be used to detect the uncoated substrate 38 on the transport tool 36 rotated to the 180 ° position. An optically coupled element 46 installed above the 0 ° position comprises: a substrate 38 on which a film on the conveying tool 36 rotated to the 0 ° position is laminated; And suction tool 28 may be used to detect uncoated substrate 38 on conveying tool 36 rotated to a 270 ° position to attach the film.

The substrate 38 before and after the programmable logic controller 34 laminates the film based on the detection result (eg, foreign matter on the surface of the substrate 38 or bubbles generated on the substrate after film lamination). In determining the quality of the controller, the programmable logic controller 34 generates a notification message such as a beep or flashing light.

5 shows a flow chart of a first embodiment of a film lamination method according to the presently disclosed invention.

Programmable logic controller 34 performs an initialization procedure (step S50) to preset various parameters in programmable logic controller 34. If the programmable logic controller 34 does not complete the initialization procedure, the programmable logic controller 34 generates a notification message such as a warning sound to notify the operator (step S52). At this point, the operator can inspect and repair the programmable logic controller 34 and then cause the programmable logic controller 34 to repeat step S50 after completing the inspection and repair.

After the programmable logic controller 34 finishes the initialization procedure, the programmable logic controller 34 controls the suction tool 28 to return to the initial position based on the preset parameters (step S54).

The programmable logic controller 34 determines whether the suction tool 28 has returned to the initial position (step S58). If the programmable logic controller 34 determines that the suction tool 28 has not returned to its initial position, the operator controls the suction tool 28 in a manual manner to return to the initial position (step S56). The programmable logic controller 34 can then be caused to repeat steps S54 and S58.

If the programmable logic controller 34 determines that the suction tool 28 has returned to its initial position, the programmable logic controller 34 controls the suction tool 28 to be parallel to the upper side of the loading platform 26. (Step S60), that is, the logic controller 34 controls the suction tool 28 to move to the position of the suction film. In addition, at the same time, the programmable logic controller 34 performs the import procedure by rolling control of the rolling mechanism 24 to import the adhesive tape adhered to the film, which is then attached to the film by the loading platform 26. Move the adhesive tape.

After the suction tool 28 has moved to the upper side of the loading platform 26, the programmable logic controller 34 controls the suction tool 28 to lower toward the loading platform 26, which is the suction tool 28. To touch the film attached on the adhesive tape (step S62). The programmable logic controller 34 also controls the suction tool 28 to suck the film, which is similar to vacuum suction (step S64).

After the suction tool 28 sucks the film, the programmable logic controller 34 moves toward the conveying tool 36 to control the suction tool 28 (ie, the suction tool 28 stacks the film). To the location). On the other hand, the programmable logic controller 34 controls the rolling mechanism 24 to roll the adhesive tape. In one aspect, the film may be peeled off through the film forming process, and at the same time, the peeled off adhesive tape may be recycled to the recycling plate 44 (step S56).

As a supplementary explanation, if the programmable logic controller 34 determines that the adhesive tape loaded by the import plate 40 has already been used, the programmable logic controller 34 stops the film stacking device 20 from working. Raise a notification message that says you should. The film lamination apparatus 20 will resume the operation when the adhesive tape of the import plate 40 is detected again.

The programmable logic controller 34 controls the movement of the suction tool 28 to the position of stacking the film (step S68). During movement, the programmable logic controller 34 controls the suction tool 28 to pass through the position sensor 30 to ensure the accuracy of the film lamination on the substrate 38 in accordance with the detection result of the position sensor 30. It is set in advance to perform a positioning procedure. In this embodiment, for example, the position sensor 30 is used to detect the position angle of the film sucked by the suction tool 28. Therefore, the position sensor 30 can detect the position angle and determine whether or not the positioning procedure has ended. When the suction tool 28 finishes positioning and moves to the film stacking position, the programmable logic controller 34 also determines whether or not the transport tool 36 is in place (step S69).

If the result of step S69 is NO, this means that the conveying tool 36 is not in place yet, and thus the S69 step is repeatedly executed until the conveying tool 36 is in place. In one implementation, a procedure for importing the substrate 38 may be performed before the transport tool 36 is in place. Specifically, the workers can place the uncoated substrate 38 on the transport tool 36 (step S70). The programmable logic controller 34 then moves 90 to move the conveying tool 36 loaded with the uncoated substrate 28 down one of the optically coupled elements 46 of the photo detector 32. The rotating mechanism 23 is controlled to return by the angle (step S72). Therefore, the programmable controller 34 controls the optically coupled element 46 to automatically detect foreign matter on the uncoated substrate 38, which is then detected by the optically coupled elements 46. Based on the detected result, it may be determined whether the size and amount of the foreign matter particles on the uncoated substrate 38 meet the criteria (step S74).

If the determination result of step S74 is NO, the programmable controller 34 generates a notification message (such as an alarm sound) to notify the worker (step S76). The operator can obtain a substrate 38 from the conveying tool 36 that does not meet the criteria. Then, step S70 and subsequent steps are repeatedly performed to execute the procedure of reinserting the substrate 38 again. Alternatively, if the determination result of step S74 is YES, the programmable logic controller 34 is again angled by 90 ° to move the conveying tool 36 on which the substrate 38 is placed to the film stacking position. The rotary mechanism 23 is controlled to turn by. At this time, the programmable controller 34 may determine whether the conveying tool 36 has been placed in place in the face of the determination step S69. Next, the programmable logic controller 34 controls the suction tool 28 to perform film lamination for attaching the film to the uncoated substrate 38 which has passed the detection (step S80).

Next, the programmable logic controller 34 determines whether or not film lamination is finished (step S82). If the determination result of step S82 is NO, step S82 is repeatedly performed to continue lamination. If the determination result of step S82 is YES, the programmable logic controller 34 controls the suction tool 28 to stop sucking the film, and the suction tool 28 to deviate from the laminated substrate 38. Control (step S84).

After finishing the film lamination, the programmable logic controller 34 again controls the suction tool 28 to return to the initial position and again by 90 ° angle, in addition to repeating steps S60 and subsequent processing steps. The rotating mechanism 23 is controlled to turn, which is used to move the conveying tool 36 on which the film-laminated substrate 38 is disposed below the other optically coupled element 46 of the photodetector 32. (Step S86). In addition, the programmable logic controller 34 detects the bubbles on the substrate 38 on which the film is laminated, and determines the size of the bubbles on the substrate 38 on which the film is laminated based on the detection result of the optically coupled element 46. The optically coupled element 46 is also automatically controlled to determine whether the number meets the criteria (step S88).

If the determination result of step S88 is NO, the bubbles on the film 38 on which the film is laminated exceed the prescribed criteria, and the programmable logic controller 34 generates a notification message (such as a warning sound) to inform the operator. (Step S90). If the determination result of step S88 is YES, or after step S90, the programmable logic controller 34 controls the rotating mechanism 23 to turn by 90 ° angle (step S92), which is whether or not the detection has passed (step S92). Whether or not the workers are preset to get the substrate 38 on which the film is laminated. Also, step S70 is executed to place another uncoated substrate 38.

After implementing the above steps, the small film lamination apparatus 20 of the presently disclosed invention will finish performing foreign material detection, film lamination, and bubble detection operations on the substrate 38. Therein, this embodiment design the design of the lamination platform 22, the suction tool 28, and the photo detector 32, except for the function of acquiring automatic detection before and after laminating the film on the substrate 38. To combine. When the above-mentioned steps are repeatedly performed continuously, substrate import, detection before film lamination, film lamination, and detection after film lamination can be performed simultaneously. Therefore, this embodiment can effectively improve the production rate.

6 to 9 show a structural diagram, a side view, a back view, and a top view of a second embodiment of a film lamination apparatus according to the presently disclosed invention. The second embodiment is used to describe a large film laminating apparatus.

As shown in FIGS. 6-9, the large film lamination apparatus 100 includes a lamination platform 102, a rolling mechanism 104, a wheel rolling element 106, a header system 108, a position sensor 110, an optical beam. Detector 112, and a programmable logic controller (not shown, which is installed under film lamination apparatus 100). A programmable logic controller is used to control the operations of the stacking platform 102 and the header system 108, where the stacking platform 102 is used to carry a substrate (not shown) and the outer side of the rolling mechanism 104. You can move horizontally from the bottom.

The header system 108 is used to control the operations of the rolling mechanism 104 and the wheel rolling element 106 through the method of movement of the mechanical coupling device. The rolling mechanism 104 includes an import plate 114, at least one roller 116, and a recycle plate 118. The retraction plate 114 loads and rolls out the adhesive tape attached to the film (such as a release film). The roller 116 is disposed below the import plate 114, which is used to move and load the adhesive tape attached to the film to the film stacking position. The recycling plate 118 rolls to recycle the peeled adhesive tapes. More specifically, the header system 108 controls the rolling mechanism 104 to move and load the adhesive tape attached to the film to the film stacking position, and the wheel rolling element 106 to move to the initial position, so that the film Wait for lamination. The header system 108 also utilizes the wheel rolling lamination method to remove the film from the adhesive tape on the rolling mechanism 104 and attach the wheel rolling element 106 to attach the film to the substrate carried by the lamination platform 102. To control.

In addition, the position sensor 110 designed in this embodiment is used to detect the position of the adhesive tape attached to the film on the rolling mechanism 104. The programmable logic controller also controls the header system 108 to perform the positioning procedure based on the sensing results of the position sensor 110 to ensure the accuracy of the film stacking. The position sensor 110 may consist of several optical fibers, where in this embodiment two optical fibers are shown by way of example.

In addition, the photo detector 112 is composed of several optically coupled elements 120 (eg, charge coupled devices). In one example, this embodiment is designed with two light coupling elements 120. The photo detector 112 is used to detect spots such as scratches or foreign matter on the surface of the uncoated substrate disposed on the lamination platform 102 and bubbles on the substrate on which the film is laminated. The programmable logic controller may generate a notification message (such as a warning sound, flashing light, etc.) based on the detection result of the photo detector 112.

In actual operation, when the programmable logic controller determines that the quality of the substrate before and after film lamination is poor, the programmable logic controller will generate a notification message. By doing so, the requirement of automatically detecting the state of the substrate before and after film lamination can be achieved.

10 shows a flowchart of a second embodiment of a film lamination method according to the presently disclosed invention. The structure of the film lamination apparatus 100 shown in FIGS. 6 to 9 describes the working process of FIG. 10.

The programmable logic controller performs an initialization procedure (step S130) to preset various parameters to the programmable logic controller. If the programmable logic controller cannot terminate the initialization procedure, the programmable logic controller generates a notification message (for example, a beep) to inform the operator (step S132). The operator may perform troubleshooting for the programmable logic controller and have the programmable logic controller execute step S130 again after the troubleshooting is finished.

After the programmable logic controller finishes the initialization procedure, the programmable logic controller controls the header system 108 to return to the initial position based on the preset parameters (step S134). Since the header system 108 controls the rolling mechanism 104 and the wheel rolling element 106 through the movement method of the mechanical coupling device, when the header system 108 returns to the initial position, the rolling mechanism 104 similarly ) And the wheel rolling element 106 may return to their respective initial positions.

The programmable logic controller then determines whether or not the header system 108 has returned to its initial position (step S138). If the determination result of step S138 is NO, step S134 will be repeatedly executed until the header system 108 returns to the initial position. If the determination result of step S138 is YES, the programmable logic controller controls the rolling mechanism 104 to control the header system 108 to start the film import to perform the import procedure on the adhesive tape adhered to the film. (Step S146). Specifically, the header system 108 controls the import plate 114 to roll out the adhesive tape attached to the film and controls the recycle plate 118 to roll to pull the adhesive tape attached to the film. This causes the entire adhesive tape attached to the film to be transferred through the support and the scroll of the roller 116. In addition, after the film is peeled off the adhesive tape, the recycling plate 118 can also recycle the adhesive tape peeled off the film.

In another embodiment, when the header system 108 controls the import plate 114 to roll out the adhesive tape, the programmable logic controller determines whether the adhesive tape loaded by the import plate 114 has been used or not. It can also be judged. If an adhesive tape has been used, the programmable logic controller generates a notification message to cause the film lamination device 100 to stop working. Therefore, after replacing the adhesive tape so that the header system 108 executes step S134, and then returns to the initial position, the operator can manually control the header system 108 (step S136). .

When the step S146 is executed to move the adhesive tape attached to the film, the programmable logic controller also performs the positioning procedure based on the detection result of the position sensor 110 (step S148).

The positioning procedure specified in this embodiment can be described through the following operating specification, which uses the setting direction and the viewing angle of the film laminating apparatus 100 shown in FIG. First, the programmable logic controller controls the rolling mechanism 104 to control the header system 108 to move towards the position sensor 110 (from left to right). The position sensor 110 of the present embodiment may be designed with two optical fibers located on the same horizontal line. The horizontal line is parallel to the right side of the stacking platform 102, which allows the two optical fibers to detect the same side of the film of adhesive tape loaded by the rolling mechanism 104.

Therefore, when only one of the optical fibers detects the film, this means that the film is tilted compared to the lamination platform 102. At this point, the programmable logic controller controls the rolling system 104 to control the header system 108 to stop continuing and to rotate and move horizontally based on the vertical axis for adjustment, which is two The optical fibers make it possible to detect the film. When the two optical fibers detect the film, the programmable logic controller controls the header system 108 to stop the horizontal rotation and move in a direction (right to left) away from the position sensor 110 by a predetermined distance. The rolling mechanism 104 is controlled. Next, the programmable logic controller controls the rolling mechanism 104 to control the header system 108 to move back toward the position sensor 110 (from left to right), and the two optical fibers to the rolling mechanism 104. When detecting the loaded film, the rolling mechanism 104 is controlled to stop the progress. By doing so, the rolling mechanism 104 moves the film with the adhesive tape to the film lamination position, and the film is positioned at the correct position.

Based on the techniques mentioned above, after the positioning procedure ends in step S148, the programmable logic controller also determines whether the stacking platform 102 is in place or not (step S163). If the determination result of step S163 is NO, this indicates that the stacking platform 102 is not yet in place, and therefore step S163 is repeatedly executed until the stacking platform 102 is in place. Before the lamination platform 102 is in place, a substrate repositioning procedure is performed. Specifically, the operator can place the uncoated substrate on the lamination platform 102 (step S156), where the lamination platform 102 of the present embodiment may be designed to suck in a vacuum to fix the substrate. The programmable logic controller also controls several optically coupled elements 120 of the photodetector 112 to automatically detect foreign matter on the uncoated substrate, and the programmable logic controller detects the photodetector 112. Based on the result, it is determined whether or not the size and amount of the foreign material on the uncoated substrate meet the criteria (step S160).

If the determination result of step S160 is NO, the programmable logic controller generates a notification message (for example, an alarm sound) to notify the operator (step S162). The operator obtains a substrate from the lamination platform 102 that does not meet the criteria, and then repeats S156 and subsequent steps to perform the substrate reinsertion procedure again. On the other hand, if the determination result of step S160 is YES, the programmable logic controller controls the lamination platform 102 to be parallel to the film lamination position. At this point, the programmable logic controller may determine whether the stacking platform 102 is in place according to the determination of step S163. The programmable logic controller then controls the header rolling element 108 to control the wheel rolling element 106 to roll and apply pressure on the film to attach the film to the uncoated substrate (step S164).

Next, the programmable logic controller determines whether film lamination is finished or not (step S166). The programmable logic controller can determine whether film lamination is complete by determining the rolling distance of the wheel rolling element 106. If the determination result of step S166 is NO, step S164 is repeatedly executed to continue laminating the film. If the determination result of step S166 is YES, the programmable logic controller controls the header system 108 to stop the rolling lamination and control the wheel rolling element 106 to be separated from the laminated substrate (step S168).

After the film lamination is finished, the programmable logic controller executes step S134 repeatedly to control the header system 108 to return to the initial position, and in addition to executing subsequent process steps, the film is stacked. In order to move the substrate, the stacking platform 102 is moved from the film stacking position to the bottom surface of the light coupled elements 120 of the photo detector 112 (step S170). Further, the programmable logic controller detects bubbles on the film-laminated substrate to determine whether or not the size and amount of bubbles on the film-laminated substrate meet the criteria based on the detection result of the photo detector 112. In order to control the optically coupled elements 120 to automatically (step S172).

If the determination result of step S172 is NO, this indicates that the bubbles on the substrate on which the film is laminated exceed the specification, and therefore the programmable logic controller generates a notification message (for example, a beep sound) to inform the operator (step S176). ). If the result of the determination in step S172 is YES or after generating a notification message in step S176, the operator obtains a substrate on which the film is laminated (whether or not the detection passes), which imports another uncoated substrate. The programmable logic controller executes step S156 again.

After performing the various mentioned steps, the large film lamination apparatus 100 ends with performing foreign material detection, film lamination, and bubbles detection operations on the substrate.

The presently disclosed invention provides a method for detecting a situation of foreign matter stuck to a substrate before lamination of a film, detecting bubbles generated on the substrate after the lamination of a film, and immediately finding a substrate on which a defective film is laminated. By providing a film lamination apparatus and a film lamination method using the photodetector of a lamination apparatus, the production rate of the film lamination on a board | substrate is improved. In addition, the film laminating apparatus realizes high accuracy, high speed, and bubble prevention on the laminated film of the substrate, and achieves features of simple operation, ease of management, and strong practicality.

While specific embodiments have been shown and described, various modifications and substitutions may be made thereto without departing from the spirit and scope of the present invention. Therefore, it will be understood that the presently disclosed invention has been described by way of example and not by way of limitation.
