There is a problem in that I cannot receive incoming calls and messages.

In order to solve this problem, a band-type portable terminal has been proposed.

An example of wearing a band-type mobile terminal like clothes or accessories has been suggested, and a smart device in the form of a wristwatch worn on a wrist or an arm has been released.

A wristwatch-type smart device (hereinafter referred to as a 'smart watch') is small and light in size and can be worn on the wrist at all times to check incoming calls or messages, thereby increasing portability.

Such a smart watch is provided with a flexible PCB, and when the flexible PCB comes in direct contact with a user's wrist or arm, a wound is generated.

Therefore, in the prior art, by insert-injecting the flexible PCB into a molten resin such as silicone through an injection molding device, the terminal provided in the flexible PCB and the user's skin were protected.

For example, the cover part 62 may be bolted to the box part 61 .

As another example, fixing protrusions are formed at regular intervals on any one of the bottom surface of the cover part 62 and the upper surface edge of the box part 61, and the fixing grooves into which the fixing protrusions are inserted and fixed in the other one correspond to the fixing protrusions. may be formed at intervals.

Accordingly, the box part 61 and the cover part 62 may be coupled through a fixing protrusion inserted into the fixing groove.

The attachment part 63 is disposed above the main body 2a accommodated in the box part 61 .

The attachment part 63 is formed in an approximately 'C'-shaped cross-sectional shape, is formed in a base 631 having a bar structure, and a cylindrical shape, and is rotatably coupled to the base 631 on both sides of the shaft to be rotatable in place. A film 632a having a roller 632a formed thereon and wound to a predetermined length on the outer periphery of the roller 632, and coated with an adhesive material so that dust or foreign matter adhered to the body 2a is attached to the surface of the film 632a may include

The roller 632 and the film 632a are formed to have a width length equal to the width length of the body 2a.

The film 632a is moved by the movement driving unit 64 in a state in which a certain region is in contact with the upper surface of the main body 2a and is reciprocally moved in both directions along the longitudinal direction of the main body 2a to adsorb foreign substances or dust.

The moving driving unit 64 may be formed as a rodless cylinder or a linear cylinder to reciprocate the film 632a in both directions along the longitudinal direction of the body 2a.

The roller 632 is fixed to the shaft 632a on the base 631, and a certain area of the film 632a is in contact with the main body 2a, so that the moving driving unit 64 moves the roller 632 and the film 632a to the main body. When reciprocating along the longitudinal direction of (2a), the roller 632 is rotated in place by the film 632a causing friction with the body 2a.

Accordingly, the film 632a also rotates together with the roller 632 . As a result, several surfaces of the film 632a are in contact with the main body 2a and 2 to adsorb foreign substances or dust.

The base plate 65 is coupled to the moving driving unit 64 in the central portion of the bottom surface.

The base plate 65 is formed with a plurality of through-holes 65a spaced apart from each other in the longitudinal and transverse directions in both regions to which the moving driving unit 64 is not coupled.

The through hole 65a guides the elevation of the striking rod 67 to be described later.

The lifting plate 66 is disposed above the base plate 65 .

The lifting plate 66 may be formed of a metal material to which the electromagnet 68 is attached.

The striking rod 67 is formed in a 1:1 correspondence with the through hole 65a on the bottom surface of the lifting plate 66, respectively.

The striking rod 67 may strike the upper surface of the main body 2a through the through hole 65a. This will be described in detail below.

The electromagnet 68 is electrically attached to the lifting plate 66 . The electromagnet 68 is a magnet that is magnetized when a current flows, and returns to its original state when the current is cut off, and since this is a commercialized technology, a detailed description thereof will be omitted.

The elevating cylinder is coupled to the bottom surface of the cover portion 62 and elevates the electromagnet 68 with respect to the elevating plate 66 .

Next, the operation of the above-described addition and removal unit 60 will be described.

First, the main body 2a is introduced into the inner space of the box part 61 through the entrance hole 61b formed on the side surface of the box part 61, so that both edges of the body 2a are placed on the upper surface of the support bar 61a. each seated

At this time, the head 2b may be in a state in which it protrudes to the outside of the box part 61 or is located inside the entry/exit hole 61b.

And, the lifting plate 66 is attached to the electromagnet 68 and maintains a state spaced apart from the upper side of the base plate 65 .

Thereafter, by operating the moving driving unit 64, the roller 632 and the film 632a move along the upper surface of the main body 2a so that foreign substances or dust are attached to the film 632a.

At this time, the movement driving unit 64 may be programmed to position the attachment unit 63 in its center. Accordingly, the attachment portion 63 is located at the central portion of the main body 2a.

Then, the movement driving unit 64 moves the attachment unit 63 from the central portion of the main body 2a to the left end portion when an operation signal is applied, and then moves from the left end portion to the right end portion, and then again to the center After positioning in the part, it is programmed to stop working.

Accordingly, the film 632a is rotated with the roller 632 while moving from the central portion of the main body 2a to the left end, then from the left end to the right end, and then again to the central portion, In the process, foreign substances and dust attached to the main body 2a are adsorbed.

When the operation of the moving driving unit 64 is stopped, the power applied to the electromagnet 68 is cut off, and only the lifting plate 66 falls to the upper surface of the base plate 65 .

Accordingly, the striking rods 67 evenly strike the upper surface of the main body 2a while penetrating the through-hole 65a in a 1:1 ratio, to shake off foreign substances or dust adhered to the bottom surface of the main body 2a.

At this time, the striking rod 67 may be formed of a silicone or rubber material to prevent damage to the main body 2a.

Thereafter, the lifting cylinder 69 operates to lower the electromagnet 68 to contact the lifting plate 66 , and power is applied to the electromagnet 68 to attach the lifting plate 66 to the electromagnet 68 .

Thereafter, the lifting cylinder 69 operates to raise the electromagnet 68 , and the lifting plate 66 is spaced apart from the upper side of the base plate 65 by a predetermined distance.

After that, take out the main body 2a from the box part 61, turn it upside down 180 degrees, put it into the entrance and exit, and then seat it on the support bar 61a, and then move the driving part 64, the electromagnet 68 and the elevating cylinder ( 69) to remove foreign substances or dust from the main body 2a in the same way.
