Description
Technical Field
The present invention relates to a film cutting apparatus, and more particularly, to a film cutting apparatus, which prevents a cutting groove and a press-in frame from being worn due to a frictional force between the cutting groove and the press-in frame by forming a first coating surface along an inner side surface of the cutting groove of a cutting blade and forming a second coating surface on an outer surface of the press-in frame penetrating the cutting groove.
Background
In general, a film cutting apparatus is an apparatus that cuts a protective film attached on an outer surface of a home appliance to prevent an appearance of a housing material from being damaged or a film formed in a thin plate shape and including a semiconductor chip or a sensor in an inside thereof.
In particular, a flexible film in which a sensor, a chip, or the like for transmitting an electric signal is incorporated is cut by press-fitting in a manner corresponding to the shape of a product or is cut by press-fitting in a manner corresponding to the shape of the product for housing in the product.
Patent document 1 discloses a conventional cutting device for a protective film of a housing material. Referring to patent document 1, the apparatus includes: upper and lower coupling rods formed above and below in an opposite manner; a connecting rod provided at an edge between the upper and lower coupling rods to space the upper and lower coupling rods apart from each other; a buffer spring fastened to the outer surface of the coupling rod to apply upward and downward pressure to the upper and lower coupling rods; a cutting device fastened in a manner of penetrating the lower coupling rod; and a fixed block fixedly arranged on the bottom surface of the lower connecting rod and used for guiding the cutting device to be exposed downwards.
When the movable rod is moved, the upper connecting rod and the lower connecting rod move downwards simultaneously via the movable rod, and the guide unit of the fixing block contacts the protecting film.
Then, when the moving rod is continuously pressed downward, the fixed block closely attached to the protective film is pressed upward by the pressing force of the upper coupling rod, and thus the lower coupling rod is pressed upward to compress the buffer spring.
And, the upper end of the cutting device is pressed by the bottom surface of the upper coupling rod, and at this time, the cutter of the cutting device is maintained in a state of being exposed to the lower side of the fixed block, so as to cut the protective film.
Wherein the protective film is cut corresponding to the moving direction of the protective film cutting device by moving the protective film cutting device in one direction in a state that the cutting blade is exposed to the lower side of the fixed block.
However, according to the above-mentioned patent document 1, there is a problem that the protective film is cut by continuously punching a predetermined section of the protective film with a cutter having a sharp shape exposed to the lower side of the fixed block, and the cutting time is long due to the continuous punching, and particularly, the inner peripheral surface of the exposed hole is worn or the outer surface of the cutter is worn due to the continuous friction between the outer surface of the cutter exposed to the lower side of the fixed block and the inner peripheral surface of the exposed hole, and the exposed length of the cutter is extended due to the wear of the inner peripheral surface of the exposed hole, so that the cutting depth of the pierced film becomes unnecessarily deep, and the outer surface of the cutter is easily damaged by an external force due to the repetition of the wear of the outer surface of the cutter, and when the film is pressed by the fixed block of the lower coupling rod, the flow occurs in the film, so that it is difficult to bring the cutter into contact with a predetermined position of the film, also, it is difficult to cut the correct position of the film due to the frequent flowing of the film, resulting in an increase in the defect rate of the cut film.

Next, an air suction hose (not shown) is connected to the suction hole 200a of the press-fitting portion 200 to form a suction pressure in the suction hole 210b of the press-fitting frame 210.
The cutting unit 100 is placed on a table (not shown) and the upper surface of the lifting frame 220 of the press-in unit 200 is fixed to a lifting device (not shown) so that the cutting unit 100 and the press-in unit 200 are kept at a predetermined distance in the vertical direction.
Thereafter, after the film F is placed on the upper portion of the table frame 110 of the cutting part 100, when the lifting means (not shown) is moved up and down to press the press-in part 200, the lifting frame 220 is moved up and down along the lifting guide 130, and at this time, the film pressing part 230 is simultaneously moved down to reach the upper surface of the table frame 110.
Then, the film pressing part 230 reaching the upper surface of the table frame 110 is continuously pressed downward by a lifting device (not shown), and thus the film pressing part 230 presses the film F placed on the table frame 110 in a state of being closely attached to the table frame 110.
At this time, the lifting frame 220 is gradually moved downward while pressing the film pressing part 230 by the lifting device (not shown) to press and compress the second elastic spring 240.
The film pressing part 230 causes the guide pins 232 to penetrate through the first through holes 233, thereby guiding the guide pins 232 to be inserted into the holes H of the film F placed on the top surface of the table frame 110, and the both ends of the film F are fixed by being locked to the guide pins 232.
The press-fitting frame 210 of the press-fitting portion 200 is exposed downward through the center portion of the film pressing portion 230 to press the film F in the direction of the notch groove 121.
At this time, the guide pin 232 penetrates the second through hole 122 of the cutting blade 120 to prevent the guide pin 232 from being interfered with by the cutting blade 120.
Accordingly, the press-fitting jig 210 penetrates the cutting groove 121 of the cutting blade 120 and is exposed to the lower side of the through-hole 111 of the table frame 110, thereby cutting the film F in accordance with the shape of the cutting groove 121.
Preferably, the second coated surface 210a of the press-fitting jig 210 and the first coated surface 121a of the cutting groove 121 are formed to have a predetermined thickness so as to maintain a predetermined interval, and the press-fitting jig 210 is inserted into the cutting groove 121 as it is.
When the second coating surface 210a formed on the outer surface of the press-fitting jig 210 is rubbed against the first coating surface 121a of the cutting groove 121 and penetrates the cutting groove 121, the friction between the outer surface of the press-fitting jig 210 and the inner surface of the cutting groove 121 is prevented, and the abrasion between the outer surface of the press-fitting jig 210 and the inner surface of the cutting groove 121 is prevented.
In particular, the suction hole 210b of the press-in frame 210 exposed to the lower side of the through hole 111 forms a suction pressure by an air suction force forcibly sucked into the suction hole 220a of the lift frame 220, and the cut film F is maintained in a state of being sucked to the bottom surface of the press-in frame 210 by the suction pressure.
Thereafter, when the lifting frame 220 is lifted up by moving a lifting device (not shown) upward, the lifting frame 220 is guided by the lifting guide 130 and moved up and down, and then the film pressing part 230 pressed by the lifting frame 220 is pressed by the second elastic spring 240 to be returned to an original state to be moved up and down downward.
At this time, the lifting frame 220 is returned to the original position by a lifting device (not shown), and at the same time, the film pressing part 230 is guided by the first guide bar 231 to move up and down toward the lower portion of the press-in frame 210, thereby returning to the original position.
When the film pressing part 230 returns to the original position, the guide pins 232 are disengaged from the holes of the film F and the first passing holes 233, and the fixing of both ends of the film F is released.
When the lifting frame 220 returns to the original position, the suction force of the air sucked through the suction hole 220a is released, and thus the suction force of the suction hole 210b of the press-in frame 210 is released, so that the film F sucked to the bottom surface of the press-in frame 210 is collected.
In this case, although the case where the air suction force of the suction hole 220a is released when the elevating bracket 220 returns to the original position is described as an example, even if the elevating bracket 220 returns to the original position, the suction force of the suction hole 210b can be maintained by continuously sucking air through the suction hole 220 a.
Then, the above film F is continuously cut in a predetermined shape by the method as described above, thereby obtaining the above film F subjected to cutting.
Although the above description has been made by taking the case where the first elastic spring 150 is not fastened to the cutting part 100 as an example, when the first elastic spring 150 is fastened to the outer surface of the elevation guide bar 130 of the cutting part 100, the first elastic spring 150 is pressed and compressed by the elevation frame 220 which moves up and down, and then, when the pressure applied to the elevation frame 220 is released, the second elastic spring 240 returns to the original state, and applies pressure to the elevation frame 220 upward to return the elevation frame 220 to the original position.
When the cut shape of the film F is to be changed, the fastening member B fastened to the upper surface of the table frame 110 of the cutting part 100 is detached, the supporting frame 140 is detached first, the cutting blades 120 are detached in opposite directions, the other cutting blade 120 is slidably coupled in an opposite manner through the coupling groove 112, and then the supporting frame 140 is fastened and fixed to replace the cutting blade 120 disposed on the upper surface of the table frame 110.
Also, referring to the method of forming the first coated surface 121a of the cutting blade 120 and the second coated surface 210a of the press-in housing 210 in fig. 9, a pair of cutting blades 120 are spaced apart in opposite directions, and a coating material is applied along the inner side of the cutting groove 121 of each of the separated cutting blades 120 to a predetermined thickness to form the first coated surface 121a (S100).
In this case, the cutting blade 120 is preferably formed as
And (4) shape.
Next, a coating material is applied along the outer surface of the press-fitting jig 210 of the press-fitting portion 200 to a predetermined thickness, thereby forming a second coated surface 210b (S200).
Thereafter, the second coated surface 210b of the press-fitting jig 210 and the first coated surface 121a of the cutting groove 121 are cut to a predetermined thickness (S300) so that the second coated surface 210a of the press-fitting jig 210 is penetrated in a state of being rubbed against the first coated surface 210a of the cutting groove 121.
The cutting blade 120 and the press-fitting jig 210 coated as described above are provided in the cutting unit 100 and the press-fitting unit 200, respectively.
As described above, in the structure in which the first coating surface 121a is formed on the inner side surface of the cutting groove 121 of the cutter 100 and the second coating surface 210a rubbed with the first coating surface 121a is formed on the outer surface of the press-in frame 210 of the press-in part 200 penetrating the cutting groove 121, the second coating surface 210a of the press-in frame 210 penetrating the cutting groove 121 rubs against the first coating surface 121a of the cutting groove 121 to prevent the outer surface of the press-in frame 210 and the inner side surface of the cutting groove 121 from being worn, and the cutting blade 120 can be easily fixed to the table frame 110 by the operation of closely attaching the pair of cutting blades 120 to the coupling groove 112 of the table frame 110 in an opposite manner, and the shape of the cutting groove 121 between the cutting blades 120 can be variously changed, particularly, the film F can be cut in a manner corresponding to the shape of the cutting groove 121 by a simple process of moving the crane 220 up and down, to shorten the cutting time and increase the production of products while shortening the cutting time.
The film cutting apparatus according to the present invention described above is not limited to the above-described embodiments, but is protected by the scope of the claims, and the technical spirit of the present invention covers the scope in which any person skilled in the art to which the present invention pertains can make various modifications without departing from the gist of the present invention.
