Hereinafter, a thermal bonding apparatus for an integrated mobile device according to the present invention will be described with reference to the accompanying drawings.

1 is a view representatively showing a smartphone as an integrated mobile device (P) that can be used in the thermal bonding device of the present invention, such integrated mobile device (P) is a front glass (one side or both sides of the body 1) 2) and / or the rear case 3 (hereinafter referred to as the planar part) is integrally bonded through the face tape 4 so that the planar part can not be forcibly removed by applying heat under certain conditions. Random decomposition is not possible.

The present invention relates to a thermal bonding apparatus for an integrated mobile device (P) having a flat part that is integrally bonded to one or both surfaces of the main body 1 as described above, and is mainly required to be reassembled after repair, such as an A / S center. It will be provided in the company, but in some cases can be installed in the manufacturer's production line, of course.

Heat bonding apparatus for an integrated mobile device (P) according to the present invention, as shown in Figures 2a, 2b, jig 10 and the main body 1 and the planar part (front surface) which largely fixed the mobile device (P) And a pressing plate 20 for re-bonding the glass 2 or the rear case 3.

The jig 10 is a body 11 and a seating cushion member 12 for mounting the temporary attachment to the mobile device (P) after the main body 1 and the planar parts are separated for reasons such as repair or replacement of parts. It includes.

Although not shown in the figure, the jig 10 is slidably coupled forward and backward in a thermal bonding apparatus base (not shown) to be opened and closed by a storage type.

In addition, the pressing plate 20 applies heat and pressure to the upper surface of the mobile device P seated on the jig 10 to bond the main body 1 to the flat part.

Although not shown in the drawing, the pressing plate 20 has a built-in heating means (not shown) for heating the upper surface of the mobile device (P) to a temperature of a specific condition, can be raised and lowered on the jig (10) It is provided.

In addition, the body 11 of the jig 10 has an accommodating portion 11a having an upper surface, and is made of a hard material such as metal, and has an accommodating portion larger than the size of a general mobile device P. 11a is provided.

In addition, the seat cushion member 12 of the jig 10 is fitted to the receiving portion (11a), it is made of a flexible material, such as rubber, mobile device (P) is seated on the upper surface, the pressing plate When the pressure of the 20 is compressed to fit the mobile device (P), the shape displacement is made to fix the mobile device (P).

That is, as shown in Figure 2a, the seating cushion member 12 has a flat upper surface (flat), due to the lowering of the pressing plate 20 is placed on the top surface of the seating cushion member 12. When the mobile device P is pressed downward, the upper surface of the seat cushion member 12 is pressed downward by the pressure action, and the mobile device P is inserted into the pressed area.

At this time, while the upper surface of the seat cushion member 12 is concave in shape, the upper surface of the seat cushion member 12 surrounding the four sides of the mobile device (P) in response to this protrudes, so projecting protrusion ( 12a ') is to hold the mobile device (P), to prevent the mobile device (P) from shaking or twisting during the re-writing process.

Thus, by pressing and holding the side curved portion of the mobile device by the protrusion 12a 'using the shape displacement of the seating cushion member 12, the heat and pressure transfer of the pressing plate 20 is facilitated, and the transfer of such proper heat and pressure. Through the re-adhesion of the main body (1) and the flat part is made firm, ensuring the waterproof performance of the original specifications as it is, it is possible to prevent the waterproof performance is reduced after repair.

Furthermore, as shown in Figure 2b, the seating cushion member 12 protrudes from the upper surface along the rim of the mobile device (P) to form a seating portion (12a) and compression when pressing the pressing plate 20 It includes a mounting protrusion 12b for fixing the side portion of the mobile device (P) through the shape displacement by.

The seating protrusion 12b has a shape corresponding to the square shape of the mobile device P, and the cross section protrudes to have a semi-circular shape or a fan shape, and the inner side of the seating protrusion 12b has an inner end portion at an upper end portion thereof. It is made of a curved form that is inclined downward at an angle toward the.

The seating protrusion 12b is provided to have a larger area than the average size of the mobile device P having a similar size, so that the bottom edge of the mobile device P when the mobile device P is seated on the seating portion 12a. The additional seating protrusions 12b are supported on the curved inner surface.

In this state, when the pressing plate 20 presses the mobile device P, the pressing plate 20 is pressed downward by the pressure on the curved inner surface of the seating protrusion 12b, and in response thereto, the seating protrusion 12b moves upward. As it is expanded, the height of the protrusion is increased, and the inner surface of the seating protrusion 12b completely forms the side surface of the mobile device P, so that the mobile device P is more stably fixed.

It is possible to fix the mobile device (P) just by pressing the upper surface of the seat cushion member 12, but the area holding the side of the mobile device (P) is narrowed, the shaking or twisting of the mobile device (P) This may occur to solve the above problems by increasing the area holding the side portion of the mobile device (P) through the mounting protrusion 12b that is displaced as described above.

In addition, the pressing plate 20 protrudes from the lower surface to correspond to the mounting protrusion 12b to contact the mounting protrusion 12b when the pressing plate 20 is pressed to suppress the shape displacement of the mounting protrusion 12b. It includes a support protrusion 21.

The support protrusion 21 is preferably made of a hard material such as metal, unlike the seating protrusion 12b, and more preferably provided on the same line in a vertical direction with the upper end of the seating protrusion 12b.

The support protrusion 21 may be processed integrally with the pressing plate 20, but is preferably provided detachably in a ring shape.

Therefore, when the seating protrusion 12b expands upward due to the pressing of the pressing plate 20, the end of the seating protrusion 12b is prevented from inflating more than necessary while contacting the support protrusion 21.

The expansion pressure is generated in the outward direction when the seating protrusion 12b expands, and the seating protrusion 12b is spaced outward from the side part of the mobile device P by excessive expansion of the seating protrusion 12b. This is to prevent the bearing capacity of the mobile device P from being lowered.

Furthermore, the seating cushion member 12 is detachable from the receiving portion 11a and replaceable, and a pressing force member 13 which suppresses the expansion of the outer side of the seating protrusion 12b when the pressing plate 20 is pressed. Including,

The pressing force member 13 is coupled to the upper surface of the body 11 so that the inner end portion is in contact with the outer surface of the seating protrusion 12b while covering the outer top surface of the seating protrusion 12b.

The pressing force member 13 is coupled in a form in which the seating protrusion 12b is fitted into the inner hollow portion in a square shape corresponding to the seating protrusion 12b.

The pressing force member 13 primarily prevents the seating cushion member 12 from being separated from the receiving portion 11a,

When the mobile device P is pressed by the crimping plate 20 to compress the upper surface of the seat cushion member 12, the upper surface of the seating protrusion 12b is prevented from expanding in an upward direction in response thereto. By preventing the expansion of the seating protrusions 12b to spread outward, the mobile device P can be more firmly fixed and maintained.

And, as described above, the seating cushion member 12 can be replaced, for example, each seating cushion member depending on the case (for example, the size of the different mobile device (P) has a significant difference in size) The mounting protrusions 12b of 12 may be different in size.

The pressing force member 13 is coupled to the position adjustment from the upper surface of the body 11 inward and outward, to allow the size adjustment of the inner hollow portion.

Although not shown in the drawings, the pressing force member 13 is composed of four powders, and each powder is bolted to the body 11 to replace the powders by size.

On the other hand, when the powders of the pressing force member 13 is replaced by size, it is not possible to precisely adjust the size according to the processing error for each powder, as well as the required number of powders required for each size can be increased, It can be very cumbersome.

The present invention has been made so that the powders can be adjusted in a sliding manner so that the size of the pressing force member 13 can be more precisely and conveniently performed.

Specifically, as shown in Figure 3, the pressing force member 13 is a pair of the first powder 13A and the first powder 13A disposed on the front and rear outer portions of the seating protrusion 12b and Including a pair of second powder (13B) disposed in the left and right outer portion of the seating protrusion (12b) to cross in a direction perpendicular to each other,

The first powder 13A or the second powder 13B is provided with sliding grooves 13a formed through the inner and outer sides along the longitudinal direction, and the other powders are fitted into the sliding grooves 13a to be coupled to each other. The powder is characterized in that the position can be adjusted in the longitudinal direction of the other powder.

The pressing force member 13 is the first powder 13A can be moved back and forth in the longitudinal direction of the second powder 13B to adjust the width before and after the first powder 13A, and at the same time, the second powder 13B can also move left and right in the longitudinal direction of the first powder 13A, so that the left and right widths of the second powders 13B can be adjusted, thereby making the replacement of the seat cushion member 12 convenient and seating at the same time. The front, rear, left and right widths of the powders can be precisely and conveniently adjusted to the size of the protrusion 12b.

At this time, the pressing force member 13 has a structure in which the first and second powders 13A and 13B are movable together, and when the expansion pressure of the seating protrusion 12b acts outward, the first and second powders ( 13A) and 13B may be opened to lose support for the mounting protrusion 12b.

Accordingly, the pressing force member 13 is provided on the outer edge portion where the first and second powders 13A and 13B intersect, and the contact surfaces contacting the powders are first and second powders 13A and 13B. It includes a supporting member 14 which is slidingly coupled to both.

The support member 14 is provided with a locking projection (14a) protruding from both outer surfaces forming the inner corner portion,

The first and second powders 13A and 13B are provided with guide grooves 13b in which the engaging protrusions 14a are slidably coupled to each outer surface.

The support member 14 is coupled to the outer edge portion of the first and second powder 13A, 13B in the shape of a wedge,

When adjusting the spacing by moving only the first powder 13A or the second powder 13B, the support member 14 moves in the longitudinal direction of the fixed powder together with the moving powder to adjust the spacing for each powder.

In the state where the space adjustment of both the first and second powders 13A and 13B is completed, even if the first and second powders 13A and 13B are pushed outward due to the expansion of the seating protrusion 12b, The supporting member 14 is wedge-shaped in the outer surface of both the 1st, 2nd powder 13A, 13B, and simultaneous movement of the 1st, 2nd powder 13A, 13B is impossible, and a seating protrusion 12b is expanded to the upper side without inflating as it expands to the outside, thereby improving the support force of the seating protrusion 12b for supporting the outer side of the mobile device (P), thereby more firmly fixing the mobile device (P) It is exhausted.

At this time, the guide groove 13b of the powder (the first powder 13A on the drawing) inserted through the powder may be provided in a form shared with the sliding groove 13a.
