Mobile devices of various sizes, including a seating cushion member for fixing the mobile device It is possible to reattach the integrated mobile device with one jig without having to individually manufacture jigs suitable for each, and at the same time, the re-adhesion of the main body and flat parts is made firmly to meet the specifications of the first released mobile device. It relates to an all-in-one thermal bonding device for mobile devices that can secure waterproof performance as it is.

Recently, mobile devices such as smart phones are produced in a form in which a user cannot arbitrarily attach or detach a rear case having an integrated battery in order to obtain a miniaturization, light weight, and waterproof function.

When these all-in-one mobile devices require repair or replacement of parts, heat is applied to the front or back of the main body to forcibly tear off the front glass (liquid crystal) or rear case, and when the work is completed, the separated front After temporarily attaching the glass or rear case to the main body, it is necessary to re-attach it by applying heat and pressure under the same conditions as the first production process.

As a prior art used for bonding the body of an integrated mobile device and the front glass or rear case, Registration Office No. 20-0414503, Publication No. 10-2008-0081885, Publication Patent No. 10-2017-0034574, Publication Patent There are No. 10-2017-0104719, etc.

The prior art is the same in that it includes a jig for fixing the object to be adhered and a compression plate for applying heat and pressure to the object to be adhered in the jig,

At this time, in the reassembly of the all-in-one mobile device, thermal bonding must be performed in a completely fixed state without moving the object to be bonded, so that assembly defects do not occur and waterproof function similar to the specifications of the first product can be maintained. there is.

Therefore, conventional thermal bonding devices must have a jig that meets the specifications for each model of the mobile device, and in the production line of the manufacturer, there is no burden on the equipment investment cost of the thermal bonding device equipped with a jig suitable for the model. In the case of a workplace that requires reassembly work for repair of mobile devices, such as /S centers, there is a problem in that it is costly to provide a thermal bonding device equipped with all jigs for each model.

That is, for example, an A/S center should be equipped with all kinds of thermal bonding devices to enable reassembly of not only the recently released main model but also all other types. A lot of cost is consumed to provide a thermal bonding device for each model.

Of course, in order to solve this problem, the prior art makes it possible to attach and detach the jig for each model to the thermal bonding device so that it can be used interchangeably. The cost burden required for processing is still a big problem.

In particular, due to the release of new products according to technological development, the lifespan of mobile devices is gradually shortening, and the interval between new product launches is also very short, about once a year. It is necessary to add a bar, and the cost burden according to jig production is increasing.

Furthermore, in the case of recently released mobile devices, an internal waterproof structure is implemented through the bonding of parts, and when reassembling (gluing) flat parts after repair, it is not possible to secure the same adhesive strength as in the initial manufacturing process, resulting in a decrease in waterproof performance. there is

Therefore, there is a need for a technology that does not cause deterioration in waterproof performance due to reassembly while making the jig of the thermal bonding device necessary for reassembly after repair of the all-in-one mobile device universally available regardless of the model.

Accordingly, the present invention was devised to solve the above problems,

Regardless of model or standard, all types of all-in-one mobile devices can be universally reassembled, reducing the cost burden of additional production or purchase of jigs, manufacturing and processing jigs at low cost, as well as reassembly In order to prevent the deterioration of waterproof performance according to the above, a cushion member for seating, which is made of a soft and flexible material and is compressed to conform to the shape of the mobile device when pressurized, is installed in the receiving part of the body with an open upper surface, and the shape is displaced. An object of the present invention is to provide a thermal bonding device for an integrated mobile device.

In addition, in the present invention, a seating protrusion corresponding to the rim shape of the mobile device protrudes from the upper surface of the seating cushion member so that the outer surface of the mobile device can be more stably supported and fixed when the seating cushion member is compressed. An object of the present invention is to provide an integrated thermal bonding device for a mobile device capable of fixing while wrapping a side surface of a mobile device through shape displacement of a seating protrusion.

Furthermore, the present invention is a form corresponding to the seating protrusion on the lower surface of the compression plate so that when the seating protrusion is displaced by the compression plate, the seating protrusion protrudes more than necessary and the fixing force of the mobile device is lowered. It is an object of the present invention to provide an integrated thermal bonding device for a mobile device capable of suppressing shape displacement of a seating protrusion by protruding a supporting protrusion.

In addition, the present invention can easily replace and use the seating cushion member when the seating cushion member is worn out or damaged, and prevents the seating cushion member from being separated or separated while expanding the rest of the area except for the seating protrusion, so that the mobile device is not in position. In order to prevent twisting, an integral heat bonding device for a mobile device including a pressing member coupled to the upper surface of the body of the jig so that the inner end contacts the outer surface of the seating protrusion while covering the outer upper surface of the seating protrusion Provides a thermal bonding device for a mobile device aims to

In describing the integrated thermal bonding device for a mobile device according to the present invention, if a non-rigid rough direction standard is specified with reference to FIG. 2 for convenience, , In the detailed description and claims of the invention related to the other drawings, the direction is specified and described according to this standard unless otherwise specified.

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

1 is a view representative of a smartphone as an integrated mobile device (P) that can be used in the thermal bonding device of the present invention, such an integrated mobile device (P) has a front glass (on one or both sides of the main body 1) 2) and/or the rear case (3) (hereinafter collectively referred to as the flat part) is integrally bonded through the double-sided tape (4), and unless the flat part is forcibly torn off by applying heat under a specific condition, the flat part Arbitrary disassembly is not possible.

The present invention relates to a thermal bonding device for an integrated mobile device (P) having a flat part integrally attached to one side or both sides of the main body (1) as described above, which requires reassembly after repair, mainly at an A/S center. It will be provided in the company, but it can be installed in the production line of the manufacturer in some cases.

As shown in FIGS. 2A and 2B, the thermal bonding device for an integrated mobile device P according to the present invention includes a jig 10 for fixing the mobile device P and a main body 1 and a flat part (front side). It includes a compression plate 20 for reattaching the glass 2 or the rear case 3.

In the jig 10, for reasons such as repair or replacement of parts, the main body 1 and the flat part are separated and the temporarily attached mobile device P is seated, and the body 11 and the cushion member 12 for seating includes

Although not shown in the drawings, the jig 10 is slidably coupled to move forward and backward on a thermal bonding device base (not shown), and is opened and closed in a retractable manner.

In addition, the compression 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 and the flat part.

Although not shown in the drawing, the compression plate 20 has a built-in heating means (not shown) for heating the top surface of the mobile device P to a temperature under a specific condition, and can be moved up and down from the top of the jig 10. are provided

In addition, the body 11 of the jig 10 has an accommodating portion 11a with an open 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 seating cushion member 12 of the jig 10 is inserted into the receiving portion 11a and is made of a soft, flexible material such as rubber, so that the mobile device P is seated on the upper surface, and the compression plate When the pressure of (20) is compressed to fit the mobile device (P), shape displacement is made to fix the mobile device (P).

That is, as shown in FIG. 2A, the upper surface of the cushion member 12 for seating is formed to be flat, and the cushion member 12 for seating is placed on the upper surface of the cushion member 12 for seating due to the lowering of the compression plate 20. When the mobile device P is pressed downward, the upper surface of the seating cushion member 12 is pressed downward due to the pressure, and the mobile device P is inserted into the pressed part.

At this time, the upper surface of the seating cushion member 12 is concavely displaced, and as a reaction to this, the upper surface of the seating cushion member 12 that surrounds the 4-sided side parts of the mobile device P protrudes, so that the protruding portion ( 12a') holds the mobile device P, preventing the mobile device P from shaking or twisting during the reattachment process.

In this way, when the curved portion of the side of the mobile device is pressed and held by the protruding portion 12a' using the shape displacement of the cushion member 12 for seating, the heat and pressure transfer of the compression plate 20 becomes easy, and this appropriate heat and pressure transfer Through this, the re-adhesion of the main body 1 and the flat part is firmly performed, guaranteeing the waterproof performance of the first released specification as it is, and preventing the waterproof performance from deteriorating after repair.

Furthermore, as shown in FIG. 2B, the seating cushion member 12 protrudes from the upper surface along the edge shape of the mobile device P to form a seating portion 12a and is compressed when the compression plate 20 is pressed. It includes a seating protrusion 12b for fixing the side portion of the mobile device P through shape displacement by.

The seating protrusion 12b has a shape corresponding to the square shape of the mobile device P and protrudes to have a semicircular or sectoral cross section, and the inner surface of the seating protrusion 12b extends from the upper end to the inner end. It is made in a curved shape that slopes downward at a predetermined angle towards the direction.

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

In this state, when the compression plate 20 presses the mobile device P, the curved inner surface of the seating protrusion 12b is pressed downward by the pressure, and as a reaction to this, the seating protrusion 12b moves upward As it expands, the protruding height increases, so that the inner surface of the seating protrusion 12b completely surrounds 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 only by pressing the upper surface of the cushion member 12 for seating, but at this time, the area for holding the side surface of the mobile device P is narrowed, causing shaking or twisting of the mobile device P This may occur, to solve the above problem by increasing the area holding the side surface of the mobile device P through the seating protrusion 12b which is displaced in shape as described above.

In addition, the compression plate 20 protrudes from the lower surface to correspond to the seating protrusion 12b and contacts the seating protrusion 12b when the compression plate 20 is pressed to suppress the shape displacement of the seating protrusion 12b. It includes a supporting protrusion (21).

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

The supporting protrusion 21 may be integrally processed with the pressing plate 20, but it is preferable to be detachably provided in a ring shape.

Therefore, when the seating protrusion 12b expands upward due to the pressure of the compression plate 20, the end portion of the seating protrusion 12b contacts the supporting protrusion 21 to prevent it from expanding more than necessary.

This is because when the seating protrusion 12b expands, an expansion pressure is generated in the outward direction as well. As the seating protrusion 12b opens outward due to excessive expansion of the seating protrusion 12b, it is spaced apart from the side surface of the mobile device P. This is to prevent the supporting force of the mobile device P from being lowered.

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

The pressing member 13 covers the outer upper surface of the seating protrusion 12b and is coupled to the upper surface of the body 11 so that its inner end comes into contact with the outer surface of the seating protrusion 12b.

The pressing member 13 has a square shape corresponding to the seating protrusion 12b and is coupled to the inner hollow portion in a form in which the seating protrusion 12b is inserted.

This pressing member 13 primarily prevents the seating cushion member 12 from leaving the receiving portion 11a,

When the mobile device P is pressed by the compression plate 20 and the upper surface of the seating cushion member 12 is compressed, the outer upper surface of the seating protrusion 12b is prevented from expanding upward as a reaction to this, and at the same time By preventing the expanding seating protrusion 12b from opening outward, the mobile device P can be more firmly fixed and maintained.

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

Accordingly, the pressing force member 13 is coupled to be able to adjust the position inward and outward from the upper surface of the body 11, so that the size of the inner hollow portion can be adjusted.

To this end, 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 so that the powders can be replaced by size.

On the other hand, when the powders of the pressing member 13 are replaced by size, it is impossible to accurately adjust the size according to the processing error for each powder, and the number of powders required for each size may increase, and the replacement of the powders is difficult. It can be very cumbersome.

Therefore, the present invention allows the position of each powder body to be adjusted in a sliding manner so that the size of the pressing member 13 can be adjusted more precisely and conveniently.

Specifically, as shown in FIG. 3, the pressing force member 13 includes a pair of first powder bodies 13A disposed on the front and rear sides of the seating protrusion 12b, and the first powder body 13A. Including a pair of second powder bodies 13B disposed on the left and right outer portions of the seating protrusion 12b crossing in a direction orthogonal to each other,

The first powder body 13A or the second powder body 13B is provided with sliding grooves 13a formed through inner and outer surfaces along the longitudinal direction, and other powders are inserted into the sliding grooves 13a and 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 member 13 enables the first powder body 13A to move forward and backward in the longitudinal direction of the second powder body 13B, so that the front and rear width of the first powder body 13A can be adjusted, and at the same time, the second powder body 13A (13B) can also move left and right in the longitudinal direction of the first powder body (13A), so that the left and right width of the second powder body (13B) can be adjusted, so that the replacement work of the cushion member 12 for seating is convenient and seated at the same time According to the size of the protruding part 12b, the front and rear, left and right widths of the powders can be precisely and conveniently adjusted.

At this time, the pressing member 13 has a structure in which the first and second powder bodies 13A and 13B are mutually movable, and when the expansion pressure of the seating protrusion 12b acts outward, the first and second powder bodies ( 13A) (13B) may be opened and the supporting force for the seating protrusion (12b) may be lost.

Accordingly, the pressing member 13 is provided at the outer corner portion where the first and second powder bodies 13A and 13B intersect, and the contact surface contacting each powder body is the first and second powder bodies 13A and 13B. ) includes a support member 14 that is slidably coupled to all of them.

The support member 14 is provided with a locking protrusion 14a protruding from the outer surface of both sides forming the inner corner portion,

The first and second powder bodies 13A and 13B are provided with guide grooves 13b to which the locking protrusions 14a are slidably coupled to outer surfaces.

This support member 14 is coupled in a wedge shape to the outer corner portion where the first and second powder bodies 13A and 13B intersect,

When adjusting the distance by moving only the first powder body 13A or the second powder body 13B, the supporting member 14 moves in the longitudinal direction of the fixed powder body together with the moving powder body, so that the distance for each powder body can be adjusted,

In a state in which the distance adjustment of both the first and second powder bodies 13A and 13B is completed, even if the first and second powder bodies 13A and 13B are pushed outward due to the expansion of the seating protrusion 12b, Since the support member 14 is wedge-shaped on the outer surfaces of both the first and second powder bodies 13A and 13B, simultaneous movement of the first and second powder bodies 13A and 13B is impossible, so that the seating protrusion (12b) does not inflate outwardly and expands only upward, thereby improving the holding force of the seating protrusion (12b) supporting the outer portion of the mobile device (P), and fixing the mobile device (P) more firmly. It is euphoric.

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

In the above description of the present invention, the thermal bonding device for the integrated mobile device (P) has been mainly described with reference to the accompanying drawings, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, and these modifications, changes and substitutions should be construed as belonging to the protection scope of the present invention.
