The base plate 110 has a rectangular plate shape. A pair of coupling holes 112 are formed in the vicinity of both ends of the upper surface of the base plate 110 and formed with female threads 113 on the inner peripheral surface. In addition, a plurality of jig holes 115a, 115b, 115c, 115d, 115e and 115f are formed in the area between the pair of coupling holes 112 in the base plate 110.

As shown in FIG. 2, the jig holes 115a, 115b, 115c, 115d, 115e and 115f may be formed of circular jig holes 115c, 115d, 115e and 115f, 115b. The jig holes 115a, 115b, 115c, 115d, 115e and 115f are formed so as to have the same shape and position as those of the punched pieces 4a, 4b, 4c, 4d, 4e and 4f . Therefore, it is needless to say that when the punched pieces of the protective film 1 are changed, the jig holes can be variously configured accordingly.

The jig holes 115a, 115b, 115c, 115d, 115e, and 115f may be formed to have a size that is equal to or slightly smaller than the size of the punched pieces 4a, 4b, 4c, 4d, 4e, .

The upper surface of the base plate 110 is provided with a pair of height limits for covering both sides of the protective film 1 in order to prevent the protective film 1 moving on the base plate 110 from rising from the base plate 110, Lids 116 and 117 are provided. Therefore, the protective film 1 may pass through the base plate 110 while being in contact with the upper surface of the base plate 110.

As described in the background art, the protective film 1 is punched through the punching machine in the previous process, but the punching pieces 4a, 4b, 4c, 4d, 4e and 4f are not separated from the protective film 1 State.

The lifting plate 120 is formed in a rectangular plate shape having the same size as the base plate 110 and a pair of insertion pipes 123 are formed at both side ends of the base plate 120. The inner surface of the insertion tube 123 is formed with an engagement protrusion 124 facing upward and a portion of the base plate 120 corresponding to the inner circumference of the insertion tube 123 is inserted. The center axis of the insertion tube 123 has the same central axis as the engaging hole 112. [

A plurality of push rods 125a, 25b, 125c, 125d, 125e, and 125f are provided on the lower surface of the lifting plate 120 to extend downward. The push rods 125a, 125b, 125c, 125d, 125e, and 125f will be described later in detail.

The guide member 130 is formed in a circular bar shape, and is configured as a pair, and is detachably coupled to the base plate 110.

Specifically, a male screw thread 133 is formed on the outer peripheral surface of the lower end of the guide member 130, and a head 134 having a larger diameter is provided on the upper end thereof. The guide member 130 is inserted into the insertion tube 123 and the male thread 133 formed at the lower end is screwed into the female thread 113 of the coupling hole 112.

The elastic member 140 is a coil spring and is inserted between the base plate 110 and the lifting plate 120 with the guide member 130 inserted therein.

The lifting plate 120 is separated from the upper portion of the base plate 120 along the guide member 130 to be movable up and down. At this time, when the lifting plate 120 is moved upward, the engaging protrusions 124 of the insertion tube 123 are caught by the step 135 of the guide member 130, .

When the lifting plate 120 moves downward by applying an external force in the downward direction, the elastic member 140 is compressed. Thereafter, when the external force is removed, the elastic force of the elastic member 140 causes the lifting plate 120, Is returned to the home position. Here, the original value of the lifting plate 120 indicates a state in which the latching jaw 124 of the insertion tube 123 is caught by the step 135 of the guide member 130 (see FIG. 3).

Although not shown, in this embodiment, the lifting plate 120 may be configured to be periodically pressed downward by a normal solenoid. That is, since the lifting plate 120 is pressed and lifted up to the home position by the elastic member 140 by the periodic pressing operation of the solenoid, the lifting plate 120 can reciprocate up and down have.

The lower ends of the push rods 125a, 125b, 125c, 125d, 125e, and 125f fixed to the lower surface of the lifting plate 120 are lifted from the corresponding jig holes 115a, 115b, 115c, 115d, 115e, and 115f.

Hereinafter, with reference to FIGS. 3 and 4, the operation of the jig apparatus 100 for removing punching pieces of a protective film according to one embodiment of the present invention will be described.
