Description

Polarizing plate feeding device of polarizing plate cutting machine {APPARATUS FOR LCD PLATE SUPPLAY FOR CUTTING MACHINE}

The present invention relates to a polarizing plate feeder of a cutting machine for processing a polarizing plate of a computer LCD (LCD), and more specifically, one by one from the stacked position to the press die from the stacked position to cut the periphery of the polarizing plate, electrostatically It is about a polarizer feeder to prevent the multiple sheets are attached and transported at once.

In general, LCD (Liquid Crystal Display) polarizing plate is to manufacture a liquid crystal screen of a notebook, a screen of a flat panel monitor, etc., the final manufacturing process of the polarizing plate is a cutting machine as shown in Figure 1 to simultaneously cut all around will be.

The cutting machine 100 is composed of a press cutting means 110 in the center, a supply means 130 before (left part in FIG. 1), and a discharge means 120 after (right part in FIG. 1). It is done.

The press cutting means 110 is composed of an upper mold 112 having a cutting punch 111 while being up and down, and a lower mold 114 having a die 113 fixed thereunder.

The supply means 130 is a transport mechanism 133 capable of reciprocating along the rail 131 by a lead screw, the material support plate 134 of the lower side, and the transfer screw 135a for raising the support plate. ) And the support cylinder 135, and the pneumatic mechanism 136 to operate up and down while being fixed to the center of the upper plate of the transport mechanism, and the plate member 137 fixed to the rod (139a) of the pneumatic mechanism 136 And an adsorption mechanism 138 provided at a plurality of positions on the flat plate member 137.

In addition, the discharge means 120 includes a transfer film 121. That is, the synthetic resin film 121 having an arbitrary width is wound from the supply drum 122 to the die 113 of the press cutting means 110 and then to the collection drum 123, and then the press cutting means. When the cutting is completed by pressing on the die 113 of 110, the polarizing plate material W is collected and lifted by hand, and the waste on the film 121 wound by the collection drum 123 is scraped with a scraper 124. It is intended to be collected under the discharge means.

Looking at the polarizing plate cutting process by the cutting machine as described above, the polarizing plate to be cut first to be loaded on the material support plate 134 by thousands.

When the pneumatic mechanism 136 operates in the transport mechanism 133 located directly above the stacked polarizing plate, the flat plate member 137 is lowered, and at the point when the flat plate member 137 is lowered, the adsorption mechanism 138 is loaded. If one of the polarizing plate was absorbed, and the flat plate member 137 is raised again by the return operation of the pneumatic mechanism 136, one of the polarizing plates is lifted.

When the transport mechanism 133 moves on the die 113 of the press cutting means 110 in a state of lifting a single polarizing plate, the pneumatic mechanism 136 is operated again to lower the flat plate member 137 and the flat plate member 137. At the time when) is lowered, the adsorption mechanism 138 removes the adsorption force and places the polarizing plate on the die 113 (on the film passing through the strictly die).

When the transport mechanism 133 retreats to its original position, the punch 111 of the press cutting means 110 descends to perform a cutting operation, and when the cutting operation is completed, the film 121 is wound onto the collection drum 123. Therefore, it is moved to the discharge means 120 along the film 121.

On the discharge means 120, the polarizing plate is collected by hand (or automatic operation), and the remaining waste is scraped off with a scraper 124 and dropped into a collecting container (not shown).

The biggest problem among the cutting operation of the LCD polarizing plate as described above is to lift the polarizing plate only one by one by the adsorption mechanism 138 provided on the transport mechanism 133, but in fact not two, but two or more pieces together It is raised.

When two or more pieces of polarizing plates are supplied to the press cutting means 110, there are many problems, such as poor cutting, damage to punches and dies, and shortened life.

The reason why the polarizing plates are not lifted one by one, but several by one is because the material of the polarizer is not only synthetic resin but also its thickness is relatively thin and long pressed by its own weight, thereby generating static electricity.

Therefore, the present invention is to solve the problem of the conventional polarizing plate cutting device as described above, the main object of the invention is to supply the polarizing plate from the supply means to the die of the press cutting means, to remove the static electricity to be lifted one by one It is intended to be able to go further, to improve the productivity and to reduce the occurrence of defects.

In the polarizing plate cutting device of the present invention for achieving the above object, the center press cutting means consisting of an upper mold, which is capable of lifting up and down while having a cutting punch, and a lower mold having a die fixed thereunder, and an arbitrary width. A reciprocating motion along the rail by means of a discharge screw and a lead screw which allow the synthetic resin film having a film to be wound from the supply drum onto the die of the press cutting means and back to the collection drum to facilitate the discharge of the cut polarized plate on the film. A transport mechanism, a work support plate at one lower side, a transfer screw and a support cylinder for raising the work support plate, and a pneumatic mechanism that operates up and down while being fixed to the center of the upper plate of the transport mechanism; Plate member fixed to the rod of the suction member provided in a plurality of positions on the plate member In the polarizing plate cutting device made of a supply means, the flat plate member of the transport mechanism is divided into a first half plate and a second half plate, the front end of the second half plate is fixed a plurality of brackets toward the front, perpendicular to each bracket After fixing the cylinder, the first half plate member is fixed to the lower end of the rod of the vertical cylinder so as to operate individually, and installed in the transverse direction from the front in accordance with the position where the material support plate of the supply means rises, And an injection actuator having a plurality of air nozzles for injecting air and an ionizer having a supply nozzle.

Hereinafter, the configuration and operation of the present invention will be described in more detail with reference to the accompanying drawings.

2 is a front view of the polarizing plate cutting machine 100 according to the present invention, and the supply means 130 is improved.

The polarizing plate cutting machine 100 is composed of a press cutting means 110 in the center, the supply means 130 before, and the discharge means 120 thereafter is similar to the conventional.

The press cutting means 110 of the polarizing plate cutting machine 100 is capable of lifting up and down, and having an upper die 112 having a cutting punch 111 and a lower die having a die 113 fixed below. 114).

In addition, the discharge means 120 is wound so that the synthetic resin film 121 having an arbitrary width passes from the supply drum 122 to the die 113 of the press cutting means 110 to the collection drum 123 again. The cut polarizing plate material W is easy to be discharged on the film.

And the supply means 130 is a transport mechanism 133 capable of reciprocating along the rail 131 and the endless belt 132 that can be rotated forward, reverse, and the material support plate 134 of one side lower, and this material A transfer screw 135a and a support cylinder 135 for raising the support plate, and a pneumatic mechanism 136 operating up and down while being fixed to the center of the upper plate of the transport mechanism, and a rod 136a of the pneumatic mechanism 136. It is made of a supply means 130 consisting of a flat plate member 137 fixed to the) and the adsorption mechanism 138 provided at a plurality of positions on the flat plate member 137.

At this time, in the present invention, the supply means, characterized in that to improve the flat plate member 137 of the transport mechanism 133, and to provide the injection operation mechanism 140 for ion and air injection.

First, the flat plate member 137 is divided into a first half plate 137a and a second half plate 137b, and a plurality of brackets 137c are fixed to the front end of the second half plate 137b toward the front and perpendicular to each bracket. After fixing the cylinder 139, the first half plate 137a is fixed to the lower end of the rod 139a of the vertical cylinder 139 so as to operate individually.

In addition, the material support plate 134 of the supply means 130 is installed in the transverse direction from the front in accordance with the rising position, the ionizer 142 for generating ions and a plurality for supplying the generated ions The ion supply nozzle 141 and the injection operation mechanism 140 having a plurality of air nozzles 143 for injecting air is provided and configured.

The following describes the operation of the present invention configured as described above.

In the right discharging means 120 of FIG. 2, the synthetic resin film 121 is wound from the supply drum 122 onto the die 113 of the press cutting means 110, and then wound back to the collection drum 123, and FIG. 2. By stacking the material on the material support plate 134 in the left supply means 130 of the ready to work.

The height of the material (polarizing plate) placed on the material support plate 134 is detected by a separate sensor (not shown), and when the material is prepared in place, the second half of the plate member 137 ( 137b) remains, and the first half plate 137a descends primarily.

The lowering at this time is performed by lowering the rod 139a of the vertical cylinder 139 fixed on the bracket 137c of the second half plate 137b, and when the lowering is completed within the lowering stroke, the lower plate 137a An adsorption mechanism 138 provided on the bottom surface is adsorbed while being in contact with the surface of the material (polarizing plate).

At the same time as the adsorption is performed, the rod 139a of the vertical cylinder 139 is raised again, and thus only the front portion of the material W is lifted.

When lifting only the front part of the material in this way, the injection operation mechanism 140 installed in close proximity to this operates.

That is, the injection operation mechanism 140 is provided with an ionizer 142 to generate ions, which are generated through the ion supply nozzle 141 and are injected together with the air injected from the air nozzle 143. The ion provided with the air prevents the generation of static electricity as is widely known, and the air acts to separate only the uppermost sheet of material lifted by the adsorption mechanism 138 of the first half plate 137a. It is.

After ion injection and air injection of the injection operation mechanism 140 are performed, the rod 139a of the vertical cylinder 139 extends to the lower half plate 137b while the lower plate 137b is lowered. Each of the adsorption mechanisms (138) in one state can be lifted by lifting a sheet of material if the adsorption rises.

As such, when the flat plate member 137 composed of the first half plate 137a and the second half plate 137b lifts one piece of material, the entire transport mechanism 133 moves on the die 113 of the press-cutting means 110 and dies. On the 113, ie on the film 121 passed over the die.

Then, when the punch 111 of the upper die is lowered to perform a cutting operation is discharged to the discharge means 120 along the film 121 passing through the die 113.

For reference, the above-described film 121 may be discarded after several more use since the punch 111 does not cut the film even when the punch 111 is lowered to cut the material on the die 113.

In the polarizing plate cutting machine of the present invention as described in detail above, the first and second half plate members are provided in the transfer mechanism on the supply means side, and the plate members are lifted and operated separately, so that the front part of the polarizer plate material is lifted first, and here the ionizer Since the ions generated by the air can be injected together with the air to prevent static electricity, even if the material on the material support plate (polarizing plate) accumulated in the thousands is lifted by the adsorption mechanism, only one sheet can be lifted.

Therefore, according to the present invention, not only the occurrence of defects in cutting the four edges of the polarizing plate by the press, but also has various advantages such as to greatly improve the productivity.
