The power unit 71 is a linear motor and is capable of driving the movable seats 73 to reciprocate on the track base 72 in an actuating direction 42 perpendicular to the conveying direction 41. Actually, the linear motor includes a plurality of coil groups (corresponding to a stator) arranged in a line at a straight interval, and a plurality of magnet groups (corresponding to a rotor) arranged in a straight line. The track seat 72 extends longitudinally in the actuating direction 42. The movable seats 73 are mounted on the rail base 72 at right and left intervals along the actuating direction 42. The structure of the movable seats 73 is not particularly limited as long as it can be driven by the power unit 71, and can be separately provided. The printing members 74 are assembled next to each other, and the movement stroke of each of the moving seats 73 is independent.

The jets 74 are respectively coupled to one side of the movable seats 73, whereby the jets 74 are placed on the rail mounts 72 in the actuating direction 42 through the movable mounts 73. Each of the printing members 74 includes a printing body 741 assembled with the moving base 73, and a conveying pipe 742 connected to the top of the printing body 741 for providing the printing body 741 with a printing material. The printing body 741 is hollow inside and can be used to accommodate the printing material conveyed from the conveying pipe 742, and the printing body 741 has a downward facing surface and can spray the printing material downward. A nozzle 743 on the surface of the polarizing film 31. The jets 74 can be reciprocated along the actuating direction 42 by the moving blocks 73, that is, the jets 74 can be driven to reciprocate horizontally by the power unit 71.

The cutting mechanism 8 is located on one side of the printing mechanism 7, and includes a plurality of cutters (not shown) that can be driven to move up and down. When the cutting mechanism 8 is moved downward for cutting, the polarizing film 31 printed by the printing mechanism 7 can be cut into the plurality of polarizing plates 32.

The suction mechanism 9 is horizontally movable in the conveying direction 41 and is also movable up and down. The suction mechanism 9 includes a plurality of blank suction cups 91 movable up and down, and the suction suction cups 91 can move downward and suck the polarizing plates 32, and then move away from the cutting mechanism 8, that is, along the The conveying direction 41 is moved downstream to convey the polarizing plates 32 to the downstream position.

Specifically, when the present invention is used, the polarizing film 31 can be held by the film clamping mechanism, not shown, and wound from the reel 6 and moved toward the conveying direction 41. When the polarizing film 31 is transported under the printing mechanism 7, the printing mechanism 7 can perform position adjustment before printing. Since each of the printing members 74 can reciprocate along the operating direction 42, the printing members 74 can be driven to be respectively moved to appropriate positions, and then sprayed on the printing material at predetermined positions on the polarizing film 31. Further, a plurality of marks 30 composed of the printing material are formed on the polarizing film 31. Moreover, as the polarizing film 31 continues to be transported, each of the printing members 74 is printed on a plurality of different portions of the polarizing film 31 to form one of the marks 30. Wherein, the printing material is, for example, an ultraviolet curing material. The indicia 30 are, for example, English letters, numbers, and the like.

Referring to Figures 5, 6, and 7, wherein Figure 6 shows the pattern and position of the mark 30 formed by the predetermined printing in this embodiment, and the dotted line is the subsequent polarizing film. 31 is scheduled to be cut. The polarizing film 31 is cut to obtain the polarizing plates 32, and in order to ensure that each of the polarizing plates 32 is formed with a mark 30, and because of the position and size of the marks 30 and the distance from the periphery of the polarizing plate 32, Certain specifications, plus each of the polarizing plates 32 subsequently cut may have different sizes, so that the partial printing member 74 must actually adjust its position at any time so that the printed indicia 30 falls on the polarizing film 31. Pre-determined location.

In the present embodiment, the polarizing film 31 is mainly cut out of three different sizes of polarizing plates 32. The mark 30 of the largest polarizing plate 32 is the English letter "A", and the polarizing plate 32 of the second order. The mark 30 is the English letter "B", and the mark 30 of the polarizing plate 32 having the smallest size is the English letter "C". Therefore, in the present embodiment, there are a total of seven rows of predetermined stamping marks 30, with the leftmost row being the first row and the far right row being the seventh row, wherein the first row of marks 30 are all in the English letter "C". For example, the second row of markers 30 is exemplified by the English letter "B". The third to sixth row of markers 30 are all preceded by the English letter "A", and the seventh row of markers 30 contains the English letters "B" and "C". "." Each of the marks 30 in the first, third, fourth, fifth, and sixth rows is substantially on the same straight line, and the marks 30 in the second row are not aligned in a straight line, but are slightly shifted left and right. The markers 30 in the row are also not aligned.

The printing mechanism 7 of the embodiment is provided with five printing members 74, so that two conventional fixed spray guns 75 (Fig. 5) can be additionally installed, and the fixed spray guns 75 can be used, for example, for printing. Marks 30 of row 1 and row 5, since each of the markers 30 in the two rows are on the same line, These stationary spray guns 75 are used for printing because there is no need for the stationary spray guns 75 to move left and right during printing. The five jets 74 of the present invention can be used to print the indicia 30 of the second, third, fourth, sixth, and seventh rows, respectively. Since the marks 30 in the rows 2 and 7 are not arranged in a straight line, the jet 74 for printing the two rows of marks 30 is driven and moved along after each mark 30 is printed. The direction 42 is moved to adjust the position to move to the predetermined printing position of the next mark 30. In addition, the seventh row of marks 30 includes both "B" and "C", and this portion can change the printing member 74 for printing the seventh row of marks 30 by automatic control, and automatically change the mark required for printing. 30 patterns.

Referring to FIGS. 3 and 7, after the printing is completed, the polarizing film 31 continues to be transported downstream in the conveying direction 41, and the cutting mechanism 8 lowers and cuts the polarizing film 31 to form the plurality of polarizing plates 32. Moreover, one of the marks 30 is retained on the surface of each of the polarizing plates 32 after cutting, so that each of the polarizing plates 32 can be used to identify the characteristics of the polarizing plate 32 by the mark 30 on the surface thereof. The size of the polarizing plates 32 may be the same or different, and the size of the polarizing plate 32 to be cut may be changed by adjusting the number, position and size of the cutting tools of the cutting mechanism 8. Finally, the polarizing plates 32 are driven to be transported under the suction mechanism 9, and the blank suction cups 91 of the suction mechanism 9 can respectively suck the polarizing plates 32 and transfer them to the downstream position.

In summary, the printing members 74 of the printing mechanism 7 are movable, and the application is highly flexible, and the printing members 74 can be moved to a proper position and then printed. Therefore, it is accurate to the polarizing film The predetermined position of 31 is printed with the mark 30 to achieve the effect of accurate printing. Moreover, the present invention can reduce the number of the printing members 74, because in the example of FIG. 6, if the conventional fixed spray gun design is used, it is necessary to set up up to ten spray guns to complete the required printing pattern, and the present invention It is only necessary to cooperate with the two fixed spray guns by the five jet prints 74 (or it is also possible to provide seven movable spray prints 74 without using any fixed spray gun), so that the present invention as a whole The number of prints 74 can be less than the number of conventional stationary spray guns, reducing equipment costs.

Referring to FIG. 8, a second preferred embodiment of the polarizing plate printing manufacturing apparatus of the present invention is substantially the same as the structure of the first preferred embodiment, and the difference lies in the mounting position of the printing mechanism 7 and the printing progress. the way.

The rail seat 72 of the printing mechanism 7 of the present embodiment extends in the conveying direction 41 and is reciprocally movable in the driving direction 42 while being driven, and one end of the rail seat 72 is movably assembled with a mounting seat 70. The mounting seat 70 extends in the actuating direction 42. The jets 74 are assembled to the rail mount 72 by the movable mounts 73, respectively. Moreover, since the track base 72 extends in the conveying direction 41, the printing members 74 are arranged in the conveying direction 41 on the rail seat 72, and each of the printing members 74 can be along the rail seat 72. The conveying direction 41 reciprocates and prints.

Referring to FIGS. 8 and 9, when the embodiment is used, the printing mechanism 7 can first move to the left along the operating direction 42. Each of the printing members 74 is responsible for printing to form a plurality of marks 30 arranged in a row. The markers 30 in each row of the example are spaced apart along the actuation direction 42. When the printing mechanism 7 moves to the leftmost side, the printing has completed a number of rows of marks 30 (as shown in Figure 2, second lane). Process). The polarizing film 31 is then continuously conveyed in the conveying direction 41, and the printing mechanism 7 is driven again to move rightward in the operating direction 42 and to perform printing (see the third flow of Fig. 9). After the printing mechanism 7 is repeatedly moved several times and printed, the printing on all parts of the polarizing film 31 can be completed.

In the design of this embodiment, in addition to the fact that the printing members 74 can be moved on the rail seat 72, the rail seat 72 itself can also be moved, so that the overall application flexibility is higher. Moreover, it is applicable to the printing of the mark 30 of the polarizing plate 32 of a smaller size. In general, taking FIG. 9 as an example, if a conventional fixed type spray gun is used and arranged along the actuating direction 42, it is necessary to set up dozens of spray guns, but in practice, when applied to the small-sized polarizing plate 32, the spray gun is set up. The location is limited, so it is virtually impossible to do with a stationary spray gun. The present invention adopts the movable jet printing member 74, which is applied to the small-sized polarizing plate 32, and the polarizing film 31 can be used when a large number of marks 30 need to be printed, and the number of the printing members 74 does not need to be too much. Therefore, the present invention is excellent in applicability.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
