The following examples are given to illustrate the embodiment of the laminator and the lamination method of the present invention. Among them, the laminating machine can be roughly classified into a small-sized laminating machine and a large-sized laminating machine, and the so-called small-sized laminating machine is suitable for a film of a substrate of, for example, 5 inches or less, and a large-sized laminating machine. It is suitable for a film of, for example, a substrate of 5 to 15 inches. In addition, the substrate may be made of, for example, glass, plastic, acryl or the like, and is not limited herein.

Please refer to FIG. 1 to FIG. 4 , which are respectively a perspective view, a side view, a rear view and a plan view of a first embodiment of the laminating machine of the present invention. Wherein the first embodiment is an example For example, it is used to illustrate the actual implementation of a small-sized laminating machine.

In FIG. 1 to FIG. 4, the laminating machine 20 includes a filming platform 22, a film winding mechanism 24, a film loading platform 26, a suction film fixture 28, a positioning sensor 30, and an optical detector 32. And a programmable logic controller 34. Among them, the programmable logic controller 34 is used to control the operation of the filming platform 22, the film winding mechanism 24 and the suction film fixture 28.

The filming platform 22 includes a rotating mechanism 23 and a plurality of bearing fixtures 36 (four bearing fixtures 36 in this embodiment). The bearing fixtures 36 are disposed on the rotating mechanism 23 for respectively carrying a substrate 38. The programmable logic controller 34 controls the rotating mechanism 23 of the film-laying platform 22 to operate at 90 degrees per revolution so that the substrates 38 individually placed on each of the carrier fixtures 36 are sequentially detected or coated.

The film winding mechanism 24 includes a film discharge tray 40, a drum 42 and a recovery tray 44. The film discharge tray 40 loads and rolls the tape to which the film (for example, a release film) is attached to the position of the carrier film platform 26. The drum 42 is disposed downstream of the film discharge tray 40 for supporting and conveying the tape to which the film is attached. The recovery tray 44 is rolled to recover the tape of the peeled film. Specifically, the programmable logic controller 34 controls the film discharge tray 40 to roll out the tape attached with the film, and is conveyed to the position of the carrier film platform 26 via the roller 42 and controls the recovery tray 44 via the roller. 42 scrolling to recover the tape that has been peeled off. Wherein, when the programmable logic controller 34 determines that the tape loaded by the film winding mechanism 24 is used up, the programmable logic controller 34 will send a prompt message (such as a warning sound, a flash). Etc) to inform the operator to replace the tape.

The programmable logic controller 34 controls the film holder 28 to move to the position of the carrier film platform 26 to further adsorb and peel the film, and then controls the film holder 28 to move to the carrier fixture 36 to bond the film to the substrate 38. on.

In addition, the positioning sensor 30 designed in this embodiment is used to detect the position of the film adsorbed by the suction film fixture 28. The programmable logic controller 34 further controls the film holder 28 to perform a positioning process based on the detection result of the positioning sensor 30. The positioning sensor 30 of the embodiment may be composed of, for example, a groove limit switch and an optical fiber.

Furthermore, the optical detector 32 is composed of a plurality of optical coupling elements (eg, Charge Coupled Device (CCD)) 46. This embodiment is exemplified by two optical coupling elements 46 for optical detection. One of the optical coupling elements 46 of the device 32 detects surface scratches or dust particles, etc., placed on the uncoated substrate 38 on the carrier jig 36, and the other optical coupling element 46 of the optical detector 32. Air bubbles placed on the substrate 38 of the film carrying the jig 36 are detected. After the detection of any of the optical coupling elements 46 is completed, the programmable logic controller 34 generates a prompt message based on the detection result of the optical detector 32. In this way, the programmable logic controller 34 of the present embodiment can determine the condition of the substrate 38 before and after the film coating based on the detection results of the optical detector 32 (the two optical coupling elements 46).

With the above-described structure, further illustrated by the top view of FIG. 4, the four bearing fixtures 36 of the present embodiment are respectively placed on the rotating mechanism 23, for example. The positions of 0° (top), 90° (right), 180° (bottom), and 270° (left); and the two optical coupling elements 46 are designed to be positioned above 0° and 180°, respectively. In this way, assuming that the rotating mechanism 23 is rotated 90 degrees in the clockwise direction, the operator can remove the coated substrate 38 and reposition it on the bearing fixture 36 that is fixedly rotated to 90°. The uncoated substrate 38; oppositely, the optical coupling element 46 above the 180° position is used to detect the uncoated substrate 38 on the carrying fixture 36 rotated to a position of 180°, at 0° The optical coupling element 46 above the position is used to detect the coated substrate 38 on the carrying fixture 36 rotated to a position of 0°; and the uncoated film on the carrying fixture 36 rotated to a position of 270°. The substrate 38 is provided with a film holder 28 for filming.

Then, when the programmable logic controller 34 determines, based on the detection result, that the substrate 38 has poor quality before or after the film coating (for example, the surface of the substrate 38 before the film is coated has particles larger than 1 mm or more; or the substrate 38 is bubbled after filming) The programmable logic controller 34 will issue a prompt message (such as a warning sound, a flash, etc.).

Figure 5 is a flow chart showing a first embodiment of the film coating method of the present invention. In explaining the operational flow of FIG. 5, reference is made to the various components of the laminator 20 of FIGS. 1-4.

First, the programmable logic controller 34 performs a boot initialization process to set various parameters preset within the programmable logic controller 34 (step S50). If the programmable logic controller 34 is unable to complete the power-on initialization, the programmable logic controller 34 issues a prompt message (eg, sounds a warning). The operator is notified (step S52), the operator can check and repair the programmable logic controller 34, and after completion, step S50 is repeatedly executed.

After the programmable logic controller 34 completes the power-on initialization, the programmable logic controller 34 controls the film fixture 28 to return to the home position based on the preset parameters (step S54).

The programmable logic controller 34 determines whether the film holder 28 has returned to the home position (step S58), and if the programmable logic controller 34 determines that the film holder 28 has not returned to the home position, the operator manually The suction film fixture 28 is controlled (step S56), and steps S54 and S58 are performed again.

If the programmable logic controller 34 determines that the film holder 28 has returned to the home position, the programmable logic controller 34 controls the film holder 28 to move above the carrier film platform 26 (step S60), that is, control the film. The jig 28 is moved to the position of the suction film. In addition, the programmable logic controller 34 also controls the scrolling of the film winding mechanism 24 to perform a feeding process of a film-attached tape to transport the tape-attached tape to the carrier film platform 26.

After the film holder 28 is moved over the film carrier platform 26, the programmable logic controller 34 controls the film holder 28 to descend toward the carrier film platform 26, so that the film holder 28 touches the film on the tape (step S62). ). Further, the suction film jig 28 is controlled to suction the film by vacuum suction (step S64).

After the film holder 28 adsorbs the film, the programmable logic controller 34 controls the film holder 28 to move toward the carrier fixture 36 (ie, moves toward the film position), and the programmable logic controller 34 controls the film roll. Agency 24 to scroll On the one hand, the tape can be peeled off, that is, the so-called stripping process; on the other hand, the tape of the peeled film can be simultaneously recovered in the recovery tray 44 (step S66).

Incidentally, if the programmable logic controller 34 determines that the tape loaded on the film tray 40 has been used up, the programmable logic controller 34 will issue a prompt message and suspend the current work of the laminator 20 to be renewed. When the tape on the film feed tray 40 is judged, the operation of the film laminator 20 is resumed.

The programmable logic controller 34 controls the suction jig 28 to move to the film position (step S68). During the movement, the programmable logic controller 34 presets to control the suction fixture 28 to pass the positioning sensor 30 to perform a positioning procedure according to the detection result of the positioning sensor 30, so as to ensure that the subsequent precision can be accurately The film is attached to the substrate 38. In the present embodiment, the positioning sensor 30 is, for example, used to detect a positioning angle of the film adsorbed by the film holder 28 to confirm whether the positioning is completed by detecting the positioning angle. When the positioning of the film holder 28 is completed and moved to the film position, the programmable logic controller 34 further determines whether the carrier jig 36 is in place (step S69).

If the result of the determination in step S69 is NO, it indicates that the carrier fixture 36 is not yet in place, so step S69 is repeatedly executed to wait for the bearing fixture 36 to be in place. However, the flow of steps before waiting for the load fixture 36 to be in place may be, for example, a process of executing a feed substrate 38. Specifically, the uncoated substrate 38 is placed on the carrier jig 36 by the operator (step S70). Further, the programmable logic controller 34 controls the rotating mechanism 23 to rotate 90 degrees, and will carry the uncoated film. The carrier jig 36 of the substrate 38 is moved under one of the optical coupling elements 46 of the optical detector 32 (step S72). Then, the programmable logic controller 34 controls the optical coupling element 46 to automatically detect the particles on the uncoated substrate 38, and determines the size of the particles on the uncoated substrate 38 based on the detection result of the optical coupling element 46. And whether the quantity meets the regulations (step S74).

If the result of the determination in the step S74 is negative, the programmable logic controller 34 issues a prompt message (for example, a warning sound) to notify the operator (step S76), and the operator removes the non-compliant substrate 38 from the carrier fixture 36. . Then, the step S70 and the subsequent steps are repeated to perform the flow of the feed substrate 38 again. On the other hand, if the result of the determination in the step S74 is YES, the programmable logic controller 34 controls the rotation mechanism 23 to rotate again by 90 degrees, and moves the bearing jig 36 on which the substrate 38 having passed the inspection is placed to the position at which the film is prepared. At this time, the programmable logic controller 34 can judge that the carrier fixture 36 is in place at the judgment of step S69. Next, the programmable logic controller 34 controls the film holder 28 to apply a film to adhere the film to the uncoated substrate 38 (step S80).

Next, the programmable logic controller 34 determines whether the film is completed (step S82). If the result of the determination in the step S82 is NO, the step S82 is repeated to continue the film coating. If the result of the determination in the step S82 is YES, the programmable logic controller 34 controls the suction jig 28 to stop the adsorption of the film, and controls the film holder 28 to leave the coated substrate 38 (step S84).

After the film is completed, the programmable logic controller 34 controls the rotating mechanism 23 to rotate again by 90 degrees, in addition to controlling the film holder 28 to return to the initial position and repeating the step S60 and the subsequent steps. The carrier jig 36 on which the coated substrate 38 is placed is moved below the other optical coupling element 46 of the optical detector 32 (step S86). Further controlling the other optical coupling element 46 to automatically detect the bubble on the coated substrate 38 to determine whether the size and number of bubbles on the coated substrate 38 are based on the detection result of the other optical coupling element 46. The rule is met (step S88).

If the result of the determination in the step S88 is NO, it indicates that the bubble on the substrate 38 of the film is out of specification, and the programmable logic controller 34 issues a prompt message (for example, a warning sound) to notify the operator (step S90). If the result of the determination in the step S88 is YES, or after the prompt message is sent in the step S90, the programmable logic controller 34 controls the rotating mechanism 23 to rotate by 90 degrees (step S92), so that the operator can take out the substrate 38 on which the film has been completed. Or unqualified). Further, step S70 is re-executed to reposition another uncoated substrate 38.

After performing the above steps, the substrate 38 is subjected to microparticle detection, film coating, bubble detection, and the like in the small-sized laminator 20 of the present invention. In the present embodiment, the design of the film-receiving device 22 and the optical detector 32 is matched with the film-receiving platform 22, and the substrate can be repeatedly and continuously executed, in addition to the automatic detection before and after the filming of the substrate 38. The feeding, pre-filming, laminating and post-filming inspections of 38 can be carried out simultaneously, thereby effectively improving production efficiency.

Please refer to FIG. 6 to FIG. 9 , which are respectively a perspective view, a side view, a rear view and a plan view of a second embodiment of the laminating machine of the present invention. Among them, the second embodiment is, for example, a practical embodiment for explaining a large-sized laminating machine.

In FIGS. 6 to 9, the large-sized laminating machine 100 includes a laminating platform 102, a film winding mechanism 104, a roller pressing device 106, a header system 108, a positioning sensor 110, and an optical inspection. The device 112 and a programmable logic controller (not shown, mounted under the laminator 100). The programmable logic controller is used to control the operation of the filming platform 102 and the header system 108, wherein the filming platform 102 is used to carry a substrate (not shown) and can be horizontally outside and below the film winding mechanism 104. mobile.

The header system 108 further controls the operation of the film winding mechanism 104 and the roller head unit 106 by means of interlocking mechanisms. The film winding mechanism 104 includes an ejection film tray 114, a roller 116 and a recovery tray 118. The film discharge tray 114 loads and rolls the tape to which the film (for example, a release film) is attached. The drum 116 is disposed downstream of the film discharge tray 114 for conveying and carrying the tape attached to the film to a film position. The recovery tray 118 is rolled to recover the tape of the peeled film. More specifically, the header system 108 controls the film winding mechanism 104 to transport and carry a tape attached to the film to a film position, and controls the roller head device 106 to move to a starting position to be rolled. In order to further control the roller indenter device 106, the film on the film winding mechanism 104 is peeled off by roll bonding, and the film is attached to the substrate carried by the filming platform 102.

In addition, the positioning sensor 110 designed in this embodiment is used to detect the volume. The position of the film-attached tape on the film mechanism 104. The programmable logic controller further controls the header system 108 to perform a positioning procedure based on the detection result of the positioning sensor 110 to ensure the accuracy of the subsequent coating. The positioning sensor 110 is composed of a plurality of optical fibers (this embodiment is two optical fibers).

Furthermore, the optical detector 112 is composed of a plurality of optical coupling elements (eg, Charge Coupled Device (CCD)) 120, which is exemplified by two optical coupling elements 120. The optical detector 112 is used to detect surface scratches or dust particles on the uncoated substrate placed on the film-coated platform 102, and air bubbles on the coated substrate. The programmable logic controller generates a prompt message (such as a warning sound, a flash, etc.) based on the detection result of the optical detector 112.

In actual operation, when the programmable logic controller determines that the substrate is inferior in quality before and after the film coating (for example, particles having a surface larger than 1 mm or a film after the substrate is coated), the programmable logic The controller will send a message. Thereby, the need to automatically detect the condition of the substrate before and after the film coating is achieved.

Figure 10 is a flow chart showing a second embodiment of the film coating method of the present invention. In explaining the operational flow of FIG. 10, reference is made to the various components of the laminator 100 of FIGS. 6-9.

First, the programmable logic controller performs a boot initialization process to set various parameters preset in the programmable logic controller (step S130). If the programmable logic controller cannot complete the boot initialization, The logic controller issues a prompt message (for example, an alert sound) to notify the operator (step S132), the operator removes the obstacle to the programmable logic controller, and after completion, the step S130 is re-executed by the programmable logic controller.

After the programmable logic controller completes the power-on initialization, the programmable logic controller controls the header system 108 to return to the home position according to the preset parameters (step S134), wherein the header system 108 is controlled by the linkage mechanism. The film winding mechanism 104 and the roller head device 106, therefore, when the leader system 108 is returned to the home position, the film winding mechanism 104 and the roller head device 106 will also return to the home position.

Next, the programmable logic controller determines whether the header system 108 has returned to the home position (step S138). If the result of the determination in step S138 is negative, step S134 is repeated until the header system 108 returns to the home position. If the result of the determination in the step S138 is YES, the programmable logic controller controls the film winding mechanism 104 to start filming through the header system 108 to perform a feeding process of the tape attached to the film (step S146). Specifically, the header system 108 controls the film ejection tray 114 to roll out the tape attached with the film, and controls the rolling of the recovery tray 118 to pull the tape attached with the film, so that the entire film is attached with the film. The roller 116 supports and rolls to convey. In addition, the recovery tray 118 is used to recover the tape of the peeled film after the film has been peeled off.

Incidentally, when the header system 108 controls the film tray 114 to roll out the tape, the programmable logic controller can further determine that the film tray 114 is loaded. Whether the loaded tape is used up. If the tape has been used, the programmable logic controller will issue a message and suspend the current work of the laminator 100. In this way, the operator can manually control the header system 108 after replacing the tape (step S136) to cause the header system 108 to perform step S134 and return to the home position.

When the entire tape is attached with the film tape in step S146, the programmable logic controller further performs a positioning process according to the detection result of the positioning sensor 110 (step S148).

The specific positioning procedure of this embodiment can use the set angle and direction shown in FIG. 9 to perform the following operation description: First, the programmable logic controller controls the direction of the film winding mechanism 104 toward the positioning sensor 110 through the header system 108. Move from left to right. The positioning sensor 110 of the present embodiment is designed, for example, by using two optical fibers positioned at the same horizontal line. The horizontal line is parallel to the right side of the coating platform 102, so that two optical fibers can be used to detect the film winding mechanism. The same side of the film on the tape carried by 104.

In this way, when only the optical fiber detects the film, it means that the film is skewed relative to the filming platform 102, and at this time, the programmable logic controller controls the film winding mechanism 104 to stop moving forward through the header system 108 and is based on The vertical axis adjusts the horizontal rotation so that both fibers can detect the film; and when both fibers detect the film, the programmable logic controller controls the film winding mechanism 104 to stop through the header system 108. The horizontal rotation is adjusted and moved a distance away from the positioning sensor 110 (from right to left) by a predetermined distance; after that, The programmable logic controller then controls the movement of the film winding mechanism 104 toward the positioning sensor 110 (from left to right) through the header system 108, and when the two optical fibers detect the film carried by the film winding mechanism 104, The film roll mechanism 104 is controlled to stop moving forward. Thereby, the film winding mechanism 104 transports the tape attached to the film to the film position, and the film is also in a precise position.

As described above, after the positioning procedure is completed in step S148, the programmable logic controller further determines whether the filming platform 102 is in place (step S163). If the result of the determination in step S163 is NO, it means that the laminating platform 102 is not yet in place, so step S163 is repeatedly executed to wait for the laminating platform 102 to be in place. However, the step flow before waiting for the laminating platform 102 to be in place may be, for example, a process of executing a feed substrate. Specifically, the uncoated substrate is placed on the coating platform 102 by the operator (step S156), and the coating platform 102 of the present embodiment can fix the substrate, for example, by vacuum suction. Further, the programmable logic controller controls the plurality of optical coupling elements 120 of the optical detector 112 to automatically detect the particles on the uncoated substrate, and determines the particles on the uncoated substrate according to the detection result of the optical detector 112. Whether the size and the number are in compliance with the regulations (step S160).

If the result of the determination in the step S160 is NO, the programmable logic controller issues a prompt message (for example, an alert sound) to notify the operator (step S162), and the operator removes the non-compliant substrate from the filming platform 102. Then, the step S156 and the subsequent steps are repeated to perform the flow of the substrate to be fed again. On the other hand, if the result of the determination in step S160 is YES, The programmable logic controller then controls the lamination platform 102 to move to the lamination position. At this time, the programmable logic controller can judge that the laminating platform 102 is in place in the judgment of step S163. Next, the programmable logic controller controls the roller ram device 106 to roll the film to the untested uncoated substrate by the header system 108 (step S164).

Next, the programmable logic controller determines whether the film is completed (step S166). Briefly, the programmable logic controller can determine whether the rolling distance of the roller ram device 106 reaches the length of one substrate to determine whether the film is completed. If the result of the determination in the step S166 is NO, the step S164 is repeatedly executed to continue the film coating. If the result of the determination in the step S166 is YES, the programmable logic controller controls the roller indenter device 106 to stop the rolling film through the header system 108, and controls the roller indenter device 106 to leave the coated substrate (step S168).

After the film is completed, the programmable logic controller synchronously controls the filming platform 102 to move out of the film position, in addition to repeatedly performing step S134 to control the header system 108 to return to the starting position and further performing the step flow after step S134. That is, the substrate that has been coated is moved below the plurality of optical coupling elements 120 of the optical detector 112 (step S170). The programmable logic controller then controls the optical coupling elements 120 to automatically detect the bubbles on the coated substrate to determine whether the size and number of bubbles on the coated substrate are consistent according to the detection result of the optical detector 112. It is prescribed (step S172).

If the result of the determination in the step S172 is negative, it indicates that the bubble on the substrate of the film is out of specification, and then the programmable logic controller issues a prompt message (for example, sending A warning sound is issued to notify the operator (step S176). If the result of the determination in step S172 is YES, or after the prompt message is sent in step S176, the operator takes out the substrate on which the film has been completed (test pass or fail), and then causes the programmable logic controller to re-execute step S156 to re- Feed another uncoated substrate.

After performing the above steps, the film laminator 100 of the large size of the present invention performs the operations of particle detection, film coating, and bubble detection on the substrate.

An advantage of the present invention is to provide a laminating machine and a laminating method, which use an optical detector of a laminating machine to detect the adhesion of a substrate to a substrate before the film is deposited, and to detect the occurrence of bubbles after the film is coated. The substrate with poor film coverage is found in time to achieve the effect of improving the overall yield of the substrate film, and the film laminating machine realizes high precision, high speed and no bubble of the substrate film, and at the same time, the operation is simple, easy to manage and practical. Features.

The present invention has been described above with reference to the preferred embodiments and the accompanying drawings, and should not be considered as limiting. Various modifications, omissions and changes may be made without departing from the scope of the invention.
