As is known, a flat CRT is a panel in which a fluorescent film is coated on its inner surface, which is disposed on the front of a TV receiver or a monitor to properly synthesize light emitted from an electron gun to reproduce a color screen on a screen. As shown in the drawing, inside the panel P, a shadow mask having numerous slit-shaped holes formed to select a color of light scanned from the electron gun is arranged at regular intervals on the inner surface of the panel P. P1, hereinafter mixed with the protrusions, are usually arranged in a rectangular shape.

Since the protrusion p1 has an angular cross-sectional shape, such as a rectangular cross section or a triangular cross section, is formed in the panel before application of the photosensitive film, causing a problem in automatically applying the photosensitive film as described above.

In view of this, the film laminating apparatus of the present invention, as shown in Figure 1, consisting of a plurality of panel conveying roll 11, the panel conveying unit 10 for linearly conveying the panel P having a projection p1, and A film supply unit 20 for supplying the photosensitive film F to be adhered to the panel P transported by the panel transport unit 10, and a film supply unit installed in the middle of the panel transport unit 10. A film temporary adhesion unit 30 for temporarily bonding the photosensitive film F supplied from the panel 20 to each panel P, and a rear side of the film temporary adhesion unit 30, which is connected to the panel P. A film pressing unit 40 for pressing and temporarily bonding the temporarily bonded photosensitive film F, and a film cutter installed at one side of the film temporary adhesive unit 30 to cut the photosensitive film F to an appropriate length ( 50).

The panel conveying unit 10 has a plurality of panel conveying rolls 11 are arranged uniformly at the same height from the ground from the inlet to the outlet of the laminating body so as to continuously convey each panel (P).

The film supply unit 20 includes a film shaft 21 on which the photosensitive film F is wound, and a film supply roll 22 that gives tension to the photosensitive film F supplied from the film shaft 21. , A cover separation roll 23 for separating a protective cover attached to the rear surface of the photosensitive film F passing through the film supply roll 22, and a take-up roller for rewinding the protective cover peeled off from the cover separation roll 23. (take up roller) 24 is made.

The film temporary adhesive unit 30 is fixed to the laminator body and interlocked up and down by a temporary adhesive pressure cylinder 31 for temporarily attaching the cylinder rod to move up and down by hydraulic and pneumatic pressure, and the temporary adhesive cylinder 31 for temporary adhesion. A transfer plate (unsigned), a temporary adhesive roller 32 fixedly attached to the other end of the transfer plate (unsigned) and interlocked up and down together, and fixed to the transfer plate to rotate the temporary adhesive roller 32. It consists of a rotating motor (not shown) for a temporary adhesive roller.

As shown in FIGS. 2A and 2B, the temporary adhesive roller 32 is formed of a hollow tube coupled to a separate vacuum device (not shown), and a plurality of communicating rollers are communicated from the hollow (not shown) to the outer circumferential surface thereof. Two suction holes 32a, and a tacking rubber having a temporary adhesion heater H for temporarily attaching an end portion of the photosensitive film F to a laminating start portion of the panel P on one side of the outer circumferential surface thereof. A recess 32c is mounted, and a recess 32c is formed at the side of the tagging rubber 32b in which the protrusion p1 of the panel P is inserted into the fitting when the photosensitive film F is temporarily attached. A cutter groove 32d is formed so that the blade tip of the film cutter unit 50 is inserted at an angle of about 90 ° from 32c.

Here, the temporary adhesive roller 32 may be a circular roller as in this embodiment, but the film temporary adhesive unit 30 itself does not adhere the film (F) to the front of the panel (P). In some cases, the present invention may be variously applied, such as a semi-circular shape, an ellipse, or a flat plate-like adhesive plate 32 'having a plurality of suction holes 32a', as shown in Japanese Patent Application Laid-Open No. 2-18030. have. In addition, in some cases, the groove 32c itself may be used as the cutter groove by adjusting the diameter of the temporary adhesion roller 32 and the like.

The film pressing unit 40 is fixed to the laminator body, the pressurizing cylinder 41 for pressing the cylinder rod is moved up and down by hydraulic and pneumatic, and the transfer plate interlocked up and down by the pressing pressure cylinder 41 (Unsigned), a pressing roller 32 fixedly attached to the other end of the conveying plate (unsigned) and interlocked up and down together, and a rotating motor for a pressing roller fixed to the conveying plate to rotate the pressing roller 32 (Not shown).

As shown in FIGS. 3A and 3B, the pressing roller 42 has a laminating heater 42a mounted at an inner center thereof, and a protrusion p1 of the panel P is disposed at one side of the outer circumferential surface of the roller 42. A groove portion 42b having a “c” shaped cross section is formed to be inserted into the fitting.

Here, the pressing roller 42 evenly presses the flat portion p2 of the panel P while the roller P also rotates in the forward direction while the panel P is being transported linearly, and then the recessed portion 42b. ) Should be inserted into the posterior protrusion p1 accurately, so that the outer circumferential length of the roller 42 except for the recess 42b (hereinafter, referred to as the outer circumferential length for convenience) proceeds to the flat portion p2 of the panel P. It is preferable to form the same distance. However, in the case of two grooves 42b, the outer circumferential surface length of the roller 42 should be 1/2 of the traveling distance of the flat portion p2 of the panel P, and in other cases according to this ratio. Various adjustments can be made.

In addition, the groove portion 42b is preferably formed to have substantially the same width and height so as to be joined to the protrusion portion p1 of the panel P. The protrusion portion p1 has a linear motion while the groove portion 42b has a linear motion. Since the rotational movement is performed, the recess 42b is slightly larger than the protrusion p1 so that the protrusion p1 and the recess 42b do not interfere with each other during the linear motion and the rotational movement. The inner side of the recess 42b is as close to the protrusion p1 as possible, so that the corners (unsigned) of the recess 42b form the flat portion p2 and the protrusion p1 of the panel P. It is desirable to be pressed against the bending point in between.

On the other hand, the groove portion may be formed in a "b" shaped cross-sectional shape, as shown in Figures 4a and 4b, in this case, the groove portion 142b should be made of two pairs symmetrical to each other and the roller ( Since the 142 rotates only 1/2, the outer circumferential surface length of the roller 142 should be about twice as long as the length of the flat portion p2 of the panel P.

In addition, as shown in FIGS. 5A and 5B, the outer peripheral surface of the pressing roller 242 is disposed between the protrusion p1 of the panel P and the plane portion p2 connected thereto instead of the recessed portion as described above. Angled pressing protrusion 242a may be formed to be custom-inserted. In this case, the length of the outer circumferential surface of the roller 242 and the traveling distance of the flat portion p2 of the panel P are adjusted so that the angled edge surface is exactly matched with the straight surface between the rearward protrusion p1 and the flat portion p2. It should be formed the same, but the actual roller 242 is rotated only about 270 °. Here, the number of the pressing protrusions 242b and the outer circumferential surface length of the roller 242 may be adjusted to have a correlation with each other.

The film cutter unit 50 uses a film cutter unit provided with a rotary blade or a linear blade which is commonly used in a laminator device for a circuit board. A description of the operation of such a film cutter unit is described in detail in Japanese Patent Application Laid-Open No. 60-85927. In the cited example, when the film is laminated on the surface of a printed circuit board, the cutter is cut without stopping the board. A method of cutting the film while moving horizontally at the same speed as the traveling speed of the substrate is described. However, in order to insert the projection p1 of the panel P into the recess 42b of the pressing roller 42, the present invention must stop the panel feed and the film supply, so that the film cutter unit 50 is left and right during this stop operation. It is also possible to cut the film F by moving to.

In addition, the temporary adhesion roller 32 by sensing the position and length of the panel P passing through the front side of the film temporary adhesive unit 30 or between the film temporary adhesive unit 30 and the film pressing unit 40. The first and second panel sensors 61 and 62 which control the operation time of the pressing roller 42 and the operation time of the film cutter unit 50 are mounted.

In addition, one side of the film pressing unit 40 is equipped with a contact temperature sensor 70 which is in contact with the outer circumferential surface of the pressing roller 42 to sense the temperature of the roller, and is detected by the contact temperature sensor 70 A control unit (not shown) for controlling the pressing heater 41 to an appropriate temperature or controlling the rotational speed of the pressing roller according to the degree is mounted.

Reference numeral 25 in the drawings denotes a film running roll.

The process of adhering the photosensitive film of the fluorescent film to the flat CRT using the present invention film laminating device as described above is as follows.

First, the photosensitive film F wound around the film shaft 21 of the film supply unit 20 maintains the proper tension via the film supply roll 22 and at the same time the cover separation roll 23 and the take-up roller 24. The protective cover of the back surface is peeled off and supplied to the film temporary adhesive unit 30 to complete the preparation for film laminating. At this time, the photosensitive film F is maintained in a state of being adsorbed to the outer peripheral surface of the roller 32 by the suction hole (32a) of the temporary adhesive roller (32).

Next, as shown in FIG. 6A, when the panel P is placed on each panel conveying roll 11 of the panel conveying unit 10 and conveyed toward the film temporary bonding unit 30, the front of the temporary adhesive roller 32 is applied. The first panel sensor 61 located on the side recognizes the starting position of the panel P, and transmits the detected information to the panel conveying unit 10 at the moment when the panel P reaches the laminating starting position. At the same time, it is transmitted to the pressure-adhesive cylinder 31 for temporary attachment, and the panel conveying unit 10 which has received this stops the panel feed roll 11, while the temporary pressure-adhesive cylinder 31 is temporarily fixed as shown in FIG. 6B. (32) is lowered so that the front projection p1 of the panel P is inserted into the recess 32b of the temporary adhesion roller 32. At this time, the tapping rubber 32b of the temporary adhesive roller 32 is contacted so as to face between the protrusion part p1 of the panel P and the flat part p2 so that the temporary adhesive heater H therein operates. The instantaneous photosensitive film F is temporarily bonded to the lamination start portion of the panel P.

Next, as shown in FIG. 6C, the vacuum device (not shown) of the temporary adhesion roller 32 is turned off and the temporary adhesion roller 31 is applied by the temporary adhesion pressure cylinder 31 while releasing the photosensitive film F adsorbed. 32) returns to its original position.

Next, the temporary adhesive roller 32 returns to its original position, and at the same time, the film transfer unit 10 is operated again to press the panel P mounted on the film transfer roll 11 as shown in FIG. 6D. The second panel detecting sensor 62 detects the position of the panel P, and the laminating start portion of the panel P reaches the vertical downward position of the pressing roller 42. The film conveying unit 10 is signaled to stop once again.

Next, the film conveying unit 10 receiving this signal stops each panel conveying roll 11, while the pressing pressure cylinder 41 of the film pressing unit 40 is operated to press the pressing roller as shown in Fig. 6E. 42 is lowered vertically, and the recess 42b of the pressing roller 42 is fitted into the dislocation side protrusion p1 of the panel P. As shown in FIG. At this time, the corner of the recess 42b of the pressing roller 42 presses a straight surface between the protrusion p1 and the flat part p2 of the panel P, so that the end of the photosensitive film F is the panel P. It is glued to the lamination start part of).

Next, the film transfer unit 10 is operated again to transfer the panel P to the right side of the drawing as shown in FIG. 6F while the pressing roller 42 is rotated counterclockwise in the drawing so that the top surface of the panel P is rotated. The photosensitive film F placed on is pressed while being heated. In this process, the film cutter unit 50 provided on one side of the temporary adhesive roller 32 is operated to cut the photosensitive film F to an appropriate length in advance. However, in some cases, the photosensitive film F may be cut in a stationary state (FIG. 6E state) before the pressing roller 42 starts main bonding.

Next, after the pressing roller 42 is completely rotated as shown in FIG. 6G and the recess 42b is inserted into the rear projection p1 of the panel P, the film transfer unit 10 as shown in FIG. 6H. Stops for a while and the pressing roller 42 returns to its original position, and then operates again to take out the panel P to the lead-out part, thereby completing the photosensitive film laminating operation for one panel P.

At this time, the process temperature of the pressing roller 42 is sensed by the contact type temperature sensor 70 which is in contact with the outer circumferential surface of the pressing roller 42 and senses the temperature of the roller 42. Whether the current pressing roller 42 is adhering the film F at a proper temperature or rotating at an appropriate speed is transmitted to the pressing heater 41 and the driving unit (not shown), thereby laminating the film. This is done uniformly.

Subsequently, as shown in FIG. 6I, the new panel P is transferred to the film temporary adhesive unit 30 through the panel transfer unit 10, and the photosensitive film F is applied to the panel P while the aforementioned series of processes are repeated. It is continuously bonded.

Meanwhile, modifications and other embodiments of the pressing roller shown in FIGS. 4A and 4B and FIGS. 5A and 5B also operate similarly to the present embodiment, and thus detailed description thereof will be omitted.

In this way, the photosensitive film can be automatically and seamlessly adhered to the panel having the protrusion, thereby eliminating the need for a separate margin, thereby preventing an increase in material cost and significantly improving productivity through automation of the film lamination process.

The film laminating apparatus according to the present invention comprises a panel conveying unit, a film supplying unit, a film pressing unit, a film pressing unit having a pressing roller, and a film cutter unit so that the film is adhered to the panel having the protrusions without gaps. Although the pressing roller is provided with a recessed portion or a pressing protrusion so that the film is adhered tightly to the contact portion between the protrusion and the flat portion of the panel, the film laminating process of adhering the film to the panel having the protrusion is automated. It can reduce the production cost and greatly increase the productivity.
