BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

FIG. 1 illustrates a protective tape bonding apparatus for bonding a protective tape to a side surface of a smartphone according to an embodiment of the present invention. Hereinafter, a protective tape adhering apparatus for adhering a protective tape to a side surface of a smartphone according to an embodiment of the present invention will be described in detail with reference to FIG.

1, the protective tape bonding apparatus includes a protective tape supply wheel, a release paper recovery wheel, a protective tape supplying member, a protective tape bonding member, a driving motor, a driving wheel, a jig, a base member, a contact member, and a fixing member. Of course, other configurations than the above-described configuration may be included in the protective tape bonding apparatus proposed in the present invention.

The protective tape supply wheel 102 is wound with a protective tape. The protective tape supply wheel 102 supplies the protective tape wound while rotating. Of course, the protective tape wound on the protective tape supply wheel 102 has a release paper on one side.

The protective tape supply member 106 includes a plurality of rotating wheels and a release separating member. The rotary wheel feeds the protective tape supplied from the protective tape supply wheel 102 to the release paper separating member. The release paper separating member separates the release paper from the supplied protective tape and provides the release paper to the release paper recovery wheel 104. Further, the release paper separating member provides the separated protective tape as a protective tape bonding member.

The release paper retrieving wheel 104 recovers the release paper provided from the release paper separating member. The release sheet recovery wheel 104 winds the release sheet provided from the release sheet separating member while rotating.

When the protective tape is supplied from the release paper separating member, the protective tape adhesive member 108 allows the protective tape to be inserted between the side surface of the smartphone and the protective tape adhesive member 108. When the protective tape is drawn between the side of the smartphone and the protective tape bonding member 108, the protective tape bonding member 108 moves to the side of the smartphone so that the protective tape can be brought into close contact with the side surface of the smartphone.

The protective tape adhesive member 108 is formed of a bar type, and the lower end portion of the protective tape adhered to the side surface of the smartphone is made of a material having elasticity. In this way, since the end portion of the protective tape bonding member is formed of a material having elasticity, the protective tape can be adhered to the side surface of the smartphone without damaging the side surface of the smartphone.

A driving motor (not shown) rotates using a power supplied from the outside. The end of the drive motor is connected to the drive wheel 110.

The driving wheel 110 is connected to the driving motor, and the driving wheel 110 rotates in the same manner as the driving motor. The driving wheel 110 is also made of a material having elasticity.

A base member (not shown) is formed of a flat plate having a predetermined thickness. A driving motor is disposed at a lower end of the base member, and a driving wheel 110 is disposed at an upper end. The base member forms a through hole at the corresponding position so that the driving motor and the driving wheel 110 can be connected. That is, the driving wheel 110 located at the upper end of the base member rotates by the rotation of the driving motor located at the lower end of the base member.

The contact member 114 is positioned at the upper end of the base member and is formed into a bar type having a predetermined length. The contact member 114 is not formed of a single member but is formed of two members having a constant spacing. A part of the driving wheel 110 is drawn in between the contact members 114 composed of two members. Of course, the driving wheel 110 is not in close contact with the contact member 114 composed of two members, but is spaced apart from the contact member 114 by a certain distance. That is, the driving wheel 110 freely rotates between the contact members 114.

The longitudinal end face of the circumferential portion of the driving wheel 110 and the longitudinal end face of the contact member 114 coincide with each other or the longitudinal end face of the circumference of the driving wheel 110 protrudes by a predetermined length from the longitudinal end face of the contact member 114 in connection with the present invention. That is, the jig 112 is brought into close contact with both the longitudinal end face of the circumference of the drive wheel 110 and the longitudinal face of the contact member 114. That is, when the longitudinal section of the circumference of the driving wheel 110 is made of a rigid material having no elasticity, the longitudinal section of the circumference of the driving wheel 110 coincides with the longitudinal section of the pressing member 114, When the longitudinal section of the circumference is made of a material having elasticity, the longitudinal section of the circumference of the driving wheel 110 protrudes from the longitudinal section of the contact member 114.

The jig 112 is located at the top of the base member. Of course, a smart phone (or a member to be bonded), which requires adhesion of the protective tape, is located at the upper end of the jig 112. The jig 112 is made of a material having elasticity. The jig 112 is brought into close contact with the driving wheel 110, and the jig 112 is also moved by the rotation of the driving wheel 110.

The jig 112 has the same rectangular shape as that of the smartphone, and the cross-sectional area is larger than the cross-sectional area of the smartphone. The corner of the jig 112 is rounded so that the jig 112 can rotate smoothly. The jig 112 is rotated by the rotation of the driving wheel 110 as described above. The detailed structure of the jig 112 will be described later.

The fixing member (not shown in Fig. 2) is positioned at the upper end of the base member, and is formed into a bar type having a predetermined length. The fixing member guides the jig 112 to move in a state in which it is in close contact with the driving wheel. That is, when the fixing member is not provided on the upper end of the base member, the jig 112 is not brought into close contact with the driving wheel 110. Therefore, a fixing member protruding by a predetermined length is formed at the upper end of the base member so that the jig 112 can be brought into close contact with the driving wheel 110.

In addition, the corresponding portion of the fixing member which is in close contact with the jig 112 is not fixed but rotates about the central axis. That is, when the jig 112 is rotated by the rotation of the driving wheel 110, the inside of the jig 112 is also held in tight contact with the fixing member. Therefore, when the fixing member is fixed without rotating, a frictional force is generated between the jig 112 and the fixing member, so that the jig 112 can not rotate smoothly. Therefore, the fixing member does not maintain the fixed state, but rotates about the central axis. That is, the jig 112 is constituted of a central rotary shaft and a cylindrical rotary member having a through-hole shape, which is inserted into the central shaft, and the rotary member rotates about the center shaft by the movement of the tightly fixed jig.

Further, the position of the fixing member positioned at the upper end of the base member is positioned coaxially with the center of the driving wheel. Particularly, a straight line connecting the center of the drive wheel and the fixing member and a line segment having the contact member formed of the bar type are formed to form a right angle with each other.

In addition, various configurations may be included in the protective tape bonding apparatus.

Figure 2 illustrates the shape of a base member according to one embodiment of the present invention. Hereinafter, the shape of the base member according to one embodiment of the present invention will be described in detail with reference to FIG.

According to Fig. 2, the base member forms a through hole. The through hole has a semicircular shape, and an external cable is connected to the jig through the through hole. The external cable is a vacuum cable for vacuum. The size of the through hole is formed to be relatively smaller than the size of the jig. That is, the jig is rotated at the upper end of the base member. In order to prevent the jig from falling down through the through hole, the size of the jig is formed to be relatively larger than the size of the through hole. Further, as described above, the shape of the through hole is formed in a semicircular shape, thereby preventing the rotating jig from falling to the lower end and preventing the cable from becoming entangled.

The base member also forms a fixed member 118 protruding by a predetermined length, and the material of the fixing member 118 is preferably made of a metal material. In particular, as described above, the fixing member can be rotated about the central axis Do.

In addition, the base member forms a contact member and a driving wheel. As described above, the contact member 114 is composed of two members spaced apart from each other by a predetermined distance, and the shape of the end portion is an oblique line shape. Further, the driving wheel 110 is positioned between the contact members 114 composed of two members. Of course, the drive wheel is driven by the drive motor located at the lower end of the base member.

Any one of the contact members 114 places the sensor 114-1. The sensor 114-1 senses the position of the sensing unit formed on the jig. That is, the sensor 114-1 sets the initial position of the jig to be rotated by the first recognized sensing unit, and then detects the rotation end point of the jig rotated by the recognized sensing unit.

3 shows a shape of a jig according to an embodiment of the present invention. Hereinafter, the shape of the jig according to one embodiment of the present invention will be described in detail with reference to FIG.

According to Fig. 3 (a), the jig is formed in a rectangular shape having a certain thickness. The upper end of the jig 112 is protruded to a certain height so that a smart phone (mobile terminal) can be seated thereon. Of course, the protruding portion has a flat plane shape so that the smartphone can be stably placed. A vacuum nozzle is formed on the upper end of the jig 112 having a flat planar shape. The vacuum nozzle performs a function of sucking a smartphone using a vacuum to prevent a smartphone placed in a flat plane shape from moving regardless of the rotation of the jig 112.

In addition, the length of the horizontal plane constituting the flat surface formed at the upper end is relatively smaller than the horizontal length of the smartphone, and the vertical length constituting the flat surface is also smaller than the vertical length of the smartphone. That is, a smartphone placed on a flat surface is projected out of a flat surface. As such, since the smartphone is protruded from the flat surface, the protective tape can be adhered to the side surface of the smartphone using the protective tape bonding member. In addition, the sensing unit 112-1 is formed on the top of the jig as described above.

According to Fig. 3 (b), the lower portion of the jig has a certain length of the drawn-in shape. Specifically, the lower portion of the jig is composed of a first portion, which is a frame having a predetermined width, and a second portion, which is drawn in a predetermined length, inside the frame. The width of the rim constituting the first portion is equal to the distance between the fastening member and the fastening member located at the upper end of the base member. That is, the fixing member is inserted into the second portion formed at the lower portion of the jig. As the fixing member 118 is inserted into the second portion formed at the lower portion of the jig, the rim, which is the first portion constituting the jig, Respectively.

Further, the jig in close contact with the driving wheel is rotated by driving of the driving wheel. Further, a vacuum nozzle formed at the upper end of the jig is connected to the lower end of the jig, and a fastening member is formed to fasten the external vacuum cable. That is, in the present invention, the vacuum cable is fastened to the jig using the fastening member. By forming the bottom end of the jig like this, it is possible to form the fastening member at the drawn-in part, and the jig can be smoothly rotated due to the weight reduction of the jig.

Hereinafter, the rotational speed of the driving wheel will be described. It is preferred that the protective tape adhered to the side of the smartphone in connection with the present invention is adhered to the side of the smartphone at a constant rate. Therefore, the driving wheel needs to adjust the rotation speed to reflect this. That is, the rotational speed of the driving wheel is controlled by dividing the case of moving the side of the jig by the rotation of the driving wheel and the case of moving the edge of the jig.

That is, when the side of the jig is moved, the movement length of the jig is the same as the movement length of the side of the smartphone that is seated on the jig top. However, when the corner of the jig is moved (rotated), the movement length of the paper is different from the movement length of the smartphone seated on the jig top. That is, when the corner of the jig is moved because the area of the jig is relatively larger than the area of the smartphone, the movement length of the jig becomes larger than the movement length of the smart phone seated on the jig top. Therefore, in the case of moving the edge of the jig, it is preferable to increase the rotational speed of the driving wheel relative to the case of moving the side of the jig. By doing so, the protective tape is adhered to the side of the smartphone at the same speed. Also, the rotational speed of the driving motor is set differently according to the curvature of the jig edge. That is, as the relative curvature is larger, the rotational speed of the drive motor decreases.

Generally, a plurality of buttons are formed on the side of a smart phone. Therefore, the protective tape proposed in the present invention forms a through hole at a position corresponding to the position of the button formed on the side of the smartphone. That is, the release papers are divided into protection tape units attached to one smartphone and are adhered with protective tapes, and the protective tapes form through holes at positions corresponding to the positions of the buttons.

Hereinafter, the operation performed in the protective tape bonding apparatus will be described in detail.

4 is a flowchart illustrating an operation performed in a protective tape bonding apparatus according to an embodiment of the present invention. Hereinafter, an operation performed in the protective tape bonding apparatus according to an embodiment of the present invention will be described in detail with reference to FIG.

In step S400, the smartphone is placed on the top of the jig. When the smartphone is placed on the top of the jig, fix the smartphone to the jig using a vacuum nozzle.

In step S405, the jig is moved so that the jig is brought into close contact with the driving wheel. At the same time, the end of the protective tape separated from the release paper is adhered to the side of the smartphone using an adhesive member.

In step S410, the driving wheel is rotated using the driving motor. The jig also rotates by the rotation of the driving wheel, and the smartphone which is seated on the top of the jig also rotates. The protective tape is glued to the side of the smartphone by rotation of the smartphone. The rotation speed is adjusted according to the position of the rotating jig of the driving motor as described above.

In step S415, when the protective tape is adhered to the side surface of the smartphone, the jig is moved to collect the smartphone that is seated in the jig. Of course, the vacuum by the vacuum nozzle is suspended during smartphone collection.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the present invention .
