Description

[0001] Chamber unit for semi-finished product waterproof inspection [0002]

The present invention relates to a chamber unit for semi-finished product waterproof inspecting used for inspecting the waterproof property of a terminal semi-finished product manufactured in a process before completing a terminal as an article,

More particularly, the body and the cover, which are combined with each other to form a chamber space for waterproof inspection of semi-finished products, are assembled together during use for waterproof inspection, When used for waterproof inspection, the body and the cover are assembled in a forward direction, and when not used, the body and the cover are assembled and assembled in a reverse direction. When the body and the cover are not used, The present invention relates to a chamber unit for semi-finished product waterproof inspection which can prevent assembly of a body and a cover in a reverse direction during use,

The present invention also relates to a chamber unit for semi-finished product waterproof inspecting, which comprises a cover lifting and lowering means for easily replacing a body and a cover having different structures in accordance with the type of semi-finished product to be inspected.

With the recent development of IT technology, various portable terminals such as mobile phones, PDAs, and MP3s are being developed.

In addition, portable terminals have become increasingly expensive due to the addition of various convenient functions.

Since the portable terminal is used and carried, it can be always contacted with water. Inside the portable terminal, which is vulnerable to water, the waterproof property is a major factor that determines the quality of the terminal .

Therefore, the manufacturer of the portable terminal is concentrating on the waterproof performance in the life style even if it is not completely waterproof. In other words, when the terminal is in contact with water for a relatively short period of time, a lot of investment is made to manufacture a terminal in which water can be a life-like waterproofing that does not penetrate into the inside.

A waterproof terminal will be tested for waterproofing before launch and will only ship terminals that are not defective in waterproofing.

The applicant of the present invention proposed a waterproof inspection apparatus which can quickly and accurately perform the waterproof inspection of a waterproof terminal without damaging the terminal due to the waterproof inspection, and proposed a terminal waterproofness inspection apparatus of Registration No. 10-1197704 .

The above-mentioned terminal waterproof inspection apparatus according to the prior art, including the above-mentioned "terminal waterproofing inspection apparatus ", examines the waterproof property of the terminal with the finished product,

It is also very important to check the waterproofness of the semi-finished product manufactured in the process before the terminal is finished with the finished product.

Semi-finished products have waterproofing problems if there is a gap in the mounting area between the part and the injection part, or if there is a gap in the part itself.

If the finished product is manufactured using the semi-finished product with a problem of waterproofness, the finished product may have a problem in water resistance. At this time, the finished product is dismantled or the finished product is disassembled to separate the semi-finished product.

That is, in the case of waterproof inspection of a finished product with a problem of waterproofness, the manufacturing process is unnecessarily proceeded after the semi-finished product, and the accessories added for the finished product after the semi-finished product may be wasted and a process of disassembling the finished product may be added There is a problem.

Therefore, it is necessary to solve the above-mentioned problem by performing a waterproof inspection on the semi-finished product before it is finished with the finished product.

For reference, since a semi-finished product is formed of an injection molded product of a normal plate structure and various parts mounted on a hole portion formed in the injection molded product, a space is not formed in the inside like the finished product. Therefore, It can not be used as a device.

FIG. 1 is a photograph of a bottom case of a smart phone as an example of a semi-finished product, in which a hole for allowing parts of the battery housing member to be mounted in a subsequent process, in which parts such as a camera and a speaker are mounted on an injection molding, And a plurality of holes such as a hole for assembly and coupling are formed.

Semi-finished products have different shapes and sizes of injection molds, different types and locations of mounted parts, and positions and sizes of holes.

Therefore, the waterproof inspection of the semi-finished product should use a body and a cover which form a chamber space corresponding to each semi-finished product.

If the finished product of the terminal has at least one semi-finished product, even if the semi-finished product is used, if the expensive part is used, the waterproof test is performed before mounting the expensive part, There is a great need to prevent the discovery of a waterproofing problem after the mounting so that expensive parts are not discarded.

In other words, several sets of body and cover are used for waterproof inspection of semi-finished products, and the waterproof inspection system changes the body and cover occasionally.

In the semi-finished product, there is an occasional replacement of the body and the cover. When the body and the cover are assembled in a forward direction, a chamber space for waterproof inspection is formed. Therefore, when the operator replaces the body and the cover, It is necessary to be able to easily confirm whether or not it is installed in the forward direction.

In addition, the body and the cover separated from the waterproof test apparatus by the replacement should be stored as a set, so that there is no need to check whether the body and the cover are set to each other at the time of replacement installation next time.

The present invention has the waterproofing inspection device for the finished product of the terminal, but there is no waterproofing inspection device for the semi-finished product before the finished product, so that the subsequent process of making the semi-finished product having a problem in waterproofing and the labor cost are wasted And to provide a chamber unit for semi-finished product waterproof inspection which can solve the above problems.

Further, when the body and the cover forming the chamber space are installed in the waterproofing inspection apparatus, it is possible to easily confirm whether the body and the cover are installed in the forward direction, and the operator can easily confirm whether or not the body and the cover are replaced, Another object of the present invention is to provide a chamber unit for waterproof inspection.

To achieve the above object, according to the present invention, there is provided a chamber unit for waterproof inspection of semifinished products,

As shown in the figure, the chamber unit for semi-finished product waterproof inspection according to the present invention comprises a body 10, a cover 20, a sealing means 30, an assembling means 40, an ascending / descending means 50, And the like.

The body (10)

A supporting part 111 on which the semi-finished product 1 is mounted is formed on an upper surface of the supporting part 111. An inner surface of the supporting part 111 supports the inner surface of the semi-finished product 1, A base plate 11 formed with protrusions 113 protruding to limit the pressing of the semi-finished product 1 when the pad 33 is pressed,

And is mounted on the upper surface of the base plate 11 so as to be wrapped around the front and rear sides of the receiving part 111. The inner surface of the receiving part 111 is formed with a U- And a jig block 13 protruding from the jig protrusions 131 for supporting the side surface of the semifinished product 1 so as to be disposed at a predetermined position.

The protrusion 113 of the base plate 11 is formed with an inflow hole 115 through which high-pressure air flows,

A rubber block 133 is provided on the inner surface of the jig block 13 so as to be able to move back and forth and a high pressure air is sprayed to the outer surface of the jig block 13 by the rubber block 133, An air inlet 35 for receiving the air of the air inlet 35 is provided.

The rubber block 133 is used to seal the hole 1a formed in the side surface of the semi-finished product 1. The inner surface pad 31 and the outer surface pad 33 are formed on the upper surface of the body 10 and the lower surface of the cover 20, It is difficult to seal the rubber block 1a and the rubber block 133 advances and retreats by air of high pressure separately. For example, the bottom case of the semi-finished product 1 of the smartphone is provided with a hole 1a to which a charging port to which a terminal of the charging cable is connected is formed on the side surface of the bottom case. Advance to seal.

The cover 20 is assembled to cover the upper portion of the body 10.

The cover 20 includes a base plate 21 and a pressing portion 23 which protrudes from the lower surface of the base plate 21 and presses the outer edge of the semi-finished product 1, (23).

The sealing means 30 is provided on the upper surface of the body 10 and the lower surface of the cover 20 so that when the cover 20 is assembled to cover the body 10, 1 to form a sealed chamber space 35 that allows inspection of the waterproofness of the components of the apparatus.

The sealing means (30)

An inner pad 31 provided on an upper surface of the receiving portion 111 of the body 10 to seal the inner surface of the semi-finished product 1 mounted on the receiving portion 111,

And an outer pad 33 provided inside the pressing portion of the cover 20 to seal the outer surface of the semi-finished product 1.

At this time, the outer surface pad 33 does not seal the entire outer surface of the semi-finished product 1 but seals the holes 1b formed in the semi-finished product 1 and the mounted parts 3 so as to be regionally separated,

In the semi-finished product 1, the holes 1b are inside the sealed chamber space 35, and the parts 3 are inside the chamber space 35 and the outside is outside the chamber space 35 .

That is, since the holes 1b of the semi-finished product 1 are present in the sealed chamber space 35, the air moving in and out of the semi-finished product 1 through the holes 1b remains in the chamber space 35, The component 3 of the component 3 and the component 3 of the component 1 are present in the sealed chamber space 35 but the outer side thereof is present in the chamber space 35. Therefore, The air in the chamber space 35 flows out of the chamber space 35 through the clearance. Therefore, when there is a problem of waterproofing the semi-finished product 1 (that is, when the air in the chamber space 35 flows out to the outside through the gap), a change in the pressure in the chamber space 35 occurs, It is possible to confirm the problem of waterproofing.

In order to seal the holes 1b formed in the semi-finished product 1 and the mounted parts 3 so as to be regionally separated, the outer pads 33 are protruded to have a closed structure A region separation protrusion 331 protruding from the outer surface of the semi-finished product 1 so that the holes of the semi-finished product 1 are disposed on the inner side and the parts 3 of the semi-finished product 1 are disposed on the outer side .

At this time, when it is difficult to arrange the holes 1b all inside the area separation protrusions 331 due to the problem of the positions of the holes 1b and the parts 3 in the semi-finished product 1, the area separation protrusions 331, The holes 1c disposed on the outer side can be individually sealed through the blocking protrusions 313 and 333 which protrude from the inner pad 31 and the outer pad 33 to block the holes 1c from the inside and the outside, respectively have.

The assembly means 40 is a means for assembling the body 10 and the cover 20. In order to form the chamber space 35 in which the region separation protrusions 331 are properly sealed, (20) can be assembled in the forward direction. That is, it can be easily confirmed whether the operator 10 assembles the body 10 and the cover 20 in the forward direction or in the reverse direction.

The assembling means 40 includes insertion grooves 41 and insertion protrusions 43 which are respectively provided on the upper surface of the body 10 and the left and right sides of the lower surface of the cover 20 so as to be male and female. Referring to the drawings, the body 10 has insertion grooves 41 formed on both left and right sides of the jig block 13, and insertion protrusions 43 (not shown) are formed on the left and right sides of the base plate 21, Is formed.

At this time, if the left and right insertion grooves 41 and the insertion protrusions 43 are formed at symmetrical positions, the insertion protrusions 43 are inserted into the insertion grooves 41 even in the forward direction as well as the reverse direction in which the front and rear positions are reversed Therefore, it is difficult to confirm whether the body 10 and the cover 20 are assembled in the forward direction or in the reverse direction unless the region separation protrusion 331 inside the cover 20 is confirmed.

The insertion protrusions 43 and the insertion protrusions 43 are provided at the asymmetric positions so that the insertion protrusions 43 are inserted into the insertion grooves 41 only when the body 10 and the cover 20 are placed in the forward direction. (41) so as to be assembled and assembled.

When the body 10 and the cover 20 are separated from each other and stored in the inspection apparatus, the body 10 and the cover 20 are stored as one set, and a set of the body 10 and the cover 20, It is necessary to prevent an accident that the body 10 or the cover 20 is turned over to the body 10 or the cover 20 of another kind.

A magnet 45 is provided on the bottom of the insertion groove 41 so that the insertion protrusion 43 is magnetically coupled to the bottom of the insertion groove 41 to separate the body 10 and the cover 20 intentionally assembled by the operator The body 10 and the cover 20 are not separated easily.

However, when the insertion protrusion 43 is engaged with the magnet 45, the cover 20 is prevented from ascending and descending by the ascending / descending means 50.

Thus, the present invention has two types of insertion grooves 41. That is, an inspection groove 411 which is provided in the inspection apparatus and to which the insertion protrusion 43 is inserted and used when it is used, a storage groove 413 which is detached from the inspection apparatus and is inserted and coupled with the insertion protrusion 43 , And the magnet (45) is provided on the bottom of the storage groove (413).

The inserting protrusion 43 is inserted into the inspecting recess 411 when the body 10 and the cover 20 are assembled in the forward direction and the inserting protrusion 433 is inserted into the inserting recess 413, The insertion protrusions 43 are inserted.

At this time, when the inspection groove 411 and the storage groove 413 are formed on both the left and right sides so that the body 10 and the cover 20 are assembled and coupled both in forward and reverse directions, It may be difficult to distinguish whether the mobile terminal 20 is coupled in the forward direction or in the reverse direction.

The depth of the storage groove 413 is shorter than the depth of the inspection groove 411 so that the gap between the body 10 and the cover 20 when the body 10 and the cover 20 are assembled and assembled Through the distance, we were able to confirm whether the worker was in the forward or reverse direction.

The lifting / lowering means (50) lifts / lowers the cover (20). That is, the cover 20 is lifted to secure a space in which the semifinished product 1 can be inserted into the body 10, and after the semifinished product 1 is loaded into the body 10, So as to cover the body 10 while pressing it, so that the closed chamber space 35 is formed.

In the waterproof testing apparatus, the cover 20 is replaced, but the lifting means 50 is not replaced. Thus, the cover 20 is preferably fast and easy to engage and disengage from the lifting means 50, and must be coupled to the correct position at the time of engagement.
