Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present application are described in detail. In the following embodiments, features of the embodiments may be combined with each other without conflict.

The term "replica" in this application refers to a modeling of the shape, dimensions (e.g., thickness, planar dimensions), constituent materials, etc. of a subject structure to achieve structural properties (including primarily structural rigidity) that remain the same or substantially the same as the subject structure. Of course, the emulation refers to a structure that can reflect the structural performance of the object structure, and need not be identical to the object structure. For example, for ease of manufacturing or cost savings, detailed structures (e.g., surface roughness, some chamfers/fillets, extremely small sized holes/grooves/protrusions, etc.) that are not relevant or less influential on the test results may not be present, cheaper or easily manufactured materials may be selected that are different from the target structure but have allowable differences in structural performance, etc. Profiling may also be directed to only a portion of the features in the object structure that affect the test results.

Examples

Some electronic equipment such as cell-phone, panel computer, intelligent wrist-watch have the decoration module for decorate and protect the region that the lid corresponds the camera behind the electronic equipment. In the production process of electronic equipment, the decoration module needs to be subjected to extrusion testing so as to verify the structural strength of the decoration module, particularly the strength of a lens of the decoration module.

The detection tool that adopts among the known art is a massive structure who has the mounting groove, when detecting, arranges the decoration module that awaits measuring in the mounting groove, can extrude the test through extrusion equipment.

In practice, the applicant finds that the results obtained by adopting the detection jig to carry out the single-body extrusion test on some types of decorative modules are different from the results obtained by the whole machine test. The difference is more remarkable especially for the situation that the stacking and connecting structure of the decoration modules in the whole machine is more complicated and/or the area of the decoration modules or the lens is larger.

For example, the decoration module 110 shown in fig. 1 or fig. 2 is an electronic device 100 (e.g., a mobile phone) with "large ring design" or "large rectangle design", the structure of stacking and supporting under the decoration module 110 is complicated, and may involve structures such as a main board, a main board bracket, a rear cover 130, etc., and the probability that the single unit extrusion test of the decoration module passes but the complete machine test cannot pass may be as high as 5-10%, which may cause the problem that the strength of the decoration module 110 (including the lens thereon) cannot be sufficiently exposed by the single extrusion test. The "large circular ring design" or the "large rectangular design" refers to a design in which the outer contour of the decoration module 110 is circular/rectangular, and the plurality of cameras 120 are circumferentially distributed on the outer periphery of the decoration module 110 and the middle portion of the decoration module 110 for connecting to other structures (such as a motherboard bracket, not shown in the figure) of the electronic device 100.

The present embodiment provides a fixture 300 for testing single extrusion of a decoration module (hereinafter referred to as a single extrusion fixture 300) for testing single extrusion of a decoration module of an electronic device. The decoration module of the electronic device may be in the shape shown in fig. 1 or fig. 2, and may also be in other shapes such as a rectangular strip, a rounded rectangle, a kidney-shaped hole, a triangle, a regular polygon (e.g., a regular hexagon, a regular octagon) or other shapes.

The consistency of the test result of the single extrusion test fixture 300 and the test result of the whole machine is obviously improved, so that a manufacturer of the decoration module 110 can pre-judge the extrusion risk of the decoration module 110 in the whole machine through the single extrusion test without waiting for the extrusion test result of the whole machine, the risk is exposed in advance, the project development time is shortened, and the cost is saved.

Fig. 3 shows a test apparatus 200 including a pressing device 210 and a one-piece pressing test fixture 300. When in use, the single extrusion testing fixture 300 can be fixed on the workbench 211 (e.g. a marble platform with larger structural rigidity) of the testing device 200, and then each decoration module 110 to be tested is sequentially installed on the single extrusion testing fixture 300, and the driving structure 212 (e.g. a hydraulic cylinder) of the extrusion device 210 drives the extrusion head 213 to extrude each extrusion test point of the decoration module 110 with a set pressure, so as to obtain a test result. The pinch test point can be selected as desired.

Fig. 4 is a schematic diagram illustrating the cooperation relationship between the single-body extrusion test fixture 300, the extrusion head 213 and the decoration module 110 in fig. 3. Referring to fig. 4, the end of the extrusion head 213 may be provided in a ball shape for extruding the decoration module 110.

The single-body extrusion test fixture 300 includes a first component and a second component. The first assembly includes a first structural portion, a second structural portion, and a third structural portion. The first structure part is plate-shaped and is used for copying a main board of the electronic equipment; the second structure part is arranged on the first structure part and is used for copying a shielding case on a mainboard of the electronic equipment; the third structure part is arranged on the first structure part and used for copying a camera of the electronic equipment. The second assembly includes a fourth feature and a fifth feature. The fourth structure part is plate-shaped, is provided with a through hole for allowing the third structure part of the copying camera to pass through, and is used for a mainboard bracket of the copying electronic equipment; the fifth structure portion is arranged on the fourth structure portion and used for matching with the rear cover 130 of the profiling electronic device to install the decoration module, and an installation position is arranged on one side, far away from the first component, of the fifth structure portion and used for installing the decoration module to be tested.

The single extrusion test fixture 300 has the advantages that the structural design and the processing are simple through the first component copying main board, the camera and the shielding cover and through the second component copying main board bracket and the part of the rear cover 130, the single extrusion test result is highly consistent with the complete machine test result, and the difference of the test results is reduced to 1-2% from 5-10% in the prior art, so that the operation mode adopting the single extrusion test as the basis of the complete machine test meets the production requirement of electronic equipment.

Fig. 5 to 11 show an embodiment of a single-body extrusion test fixture 300 of the present application.

Referring to fig. 5, the present embodiment provides a single extrusion testing fixture 300 for carrying the decoration module 110.

Referring to fig. 6, the single-body extrusion test fixture 300 includes a first assembly 10 and a second assembly 20, the second assembly 20 can be connected to the first assembly 10 in a matching manner, and a side of the second assembly 20 away from the first assembly 10 has a mounting position W1 for mounting the decoration module 110. When the device is used, the first assembly 10 is fixedly supported on the workbench 211 (shown in fig. 3), the second assembly 20 is installed on the first assembly 10, and then the decoration modules 110 to be tested are sequentially installed on the installation position W1 for single body extrusion testing.

In this embodiment, the first component 10 and the second component 20 can be detachably connected by using a screw or other connection structure, so that the first component and the second component can be conveniently formed respectively, and the manufacturing difficulty of the jig is reduced. And the first component 10 and the second component 20 which are detachably connected are used for supporting the decoration module 110, and the provided supporting environment better conforms to the mounting structure of the decoration module 110 in the whole electronic device 100, so that the difference between the single body extrusion test and the whole machine test is favorably reduced.

Referring to fig. 6, the first assembly 10 includes a first structure portion 11, a second structure portion 12, and a third structure portion 13.

The first structure portion 11 has a plate shape and is configured to follow a main board of the electronic apparatus 100. The second structure portion 12 is provided in the first structure portion 11 and is configured to follow a shield case on a main board of the electronic apparatus 100. The third structure portion 13 is provided in the first structure portion 11, and is configured to trace the camera 120 of the electronic apparatus 100. The first structure portion 11 has a first surface P1 and a second surface P2 opposite to each other, and the second structure portion 12 and the third structure portion 13 are disposed on the first surface P1 side of the first structure portion 11.

In the present embodiment, the first component 10 is designed around a PCBA (Printed Circuit Board Assembly) and the camera 120 of the electronic device 100. For the PCBA part, the characteristics of the main board and the shield cover that are critical factors for the squeeze test through mechanical analysis are retained, and electronic components such as capacitors, resistors, and conductive circuits that are arranged on the main board (which have little or no influence on the squeeze test through analysis) are omitted, thereby obtaining the first structure part 11 and the second structure part 12. For the camera 120, the characteristics of the number, position, and height of the cameras 120, which are analyzed by mechanics as the key factors for the extrusion test, can be retained, and the structures such as a Flexible Printed Circuit (FPC) and a reinforcing steel sheet (which are analyzed to have little or no influence on the extrusion test) connected to the cameras 120 are omitted, so as to obtain the third structure portion 13.

Wherein the third structure part 13 may be integrated to the first structure part 11, forming an integral structure. The integration here may be to integrally form the third structure part 13 with the same material as the first structure part 11 (e.g. by injection molding), so as to reduce the structure assembling steps. Of course, in other embodiments, the third structure portion 13 may be formed separately and connected to the first structure portion 11 by a connection structure (e.g. a screw, an adhesive layer).

Experimental analysis shows that when the overall height of the camera 120 is small, and the ratio of the height to the dimensions (such as the length, the width, and the radius) in each direction on the cross section is small, and the camera 120 is in a shape of a short and thick overall shape, only the outline of the camera 120 and the third structural portion 13 formed by the same material as the substrate of the motherboard are contoured, so that the actual camera 120 with a complex structural structure (such as the optical lens 112 and the optoelectronic component) can be accurately compared. In view of the above experimental analysis, the present embodiment may adopt a mode of only profiling the outer shape of the camera 120 and integrally integrating the solid third structural part 13 and the solid third structural part 13 formed by the same material as the substrate of the motherboard with the first structural part 11, instead of the actual camera 120 structure, so that the difficulty of design and manufacture is greatly reduced, and the cost is also reduced.

For the second structural part 12 of the conformal shielding can it can be made of the same metal material as the shielding can. In view of the fact that some of the shields are made of thin metal with small thickness and large area, and the same material as the substrate of the motherboard is used instead, which greatly affects the supporting effect, in the present embodiment, the second structure portion 12 is formed by using the same metal to profile the thickness, contour, and the like of the shield, and the second structure portion 12 is assembled to the first structure portion 11 and the third structure portion 13 which are integrally formed, thereby forming the first assembly 10.

In other cases, when the structural rigidity of the shielding case is large (such as the thickness of the shielding case is large, the area is small, or there is reliable support with the main board), the second structural portion 12 may be made of the same material as the first structural portion 11 and may be integrally formed with the first structural portion 11.

Referring to fig. 6 and 7, in the present embodiment, the first component 10 further includes a sixth structural portion 16, and the sixth structural portion 16 is used to assist in supporting the second component 20 and thus the decoration module 110. The sixth structure part 16 is connected to the first structure part 11, and includes a support part 16a and a side support block 16 b. The support portion 16a is formed to protrude from the second surface P2 of the first structure portion 11 to a side away from the first surface P1. In the present embodiment, the support portion 16a includes a plurality of bosses 16c protruding from the second surface P2, and the plurality of bosses 16c are circumferentially distributed along the outer edge of the first structure portion 11. The bottom surfaces of the plurality of bosses 16c are coplanar to define a support plane P5 for snug support against the table top of the table 211 (see fig. 3). The side support block 16b is connected to one side of the first structure part 11 and has a third surface P3 and a fourth surface P4 opposite to each other in the thickness direction of the first structure part 11, and the fourth surface P4 and the support surface P5 are coplanar, so that when the first module 10 is supported on the work table 211, the side support block 16b and the bosses 16c are supported on the work table 211 together, ensuring that the first module 10 can be supported on the work table 211 smoothly. Moreover, the bosses 16c on the outer edge and the side support blocks 16b on the side of the first structure part 11 are adopted to realize suspended support of the middle part of the first structure part 11, so that the support of the second structure part 12 and the third structure part 13 supported on the first structure part to the second assembly 20 and even the decoration module 110 is closer to the support condition of the decoration module 110 in the electronic device 100, and the difference between the single extrusion test and the whole machine test is further reduced.

In this embodiment, the sixth structure portion 16 and the first structure portion 11 may be integrally injection molded by using the same material (for example, a material such as epoxy resin) as the substrate of the main board of the electronic device 100.

In some embodiments, the first, second, third, and

sixth structures

11, 12, 13, 16 are integrally injection molded from epoxy.

Of course, in other embodiments, the first structure portion 11 may also be made of the same material as the main board (e.g., copper clad laminate).

Referring again to fig. 6 and 7, the second assembly 20 includes a fourth feature 24 and a fifth feature 25. The fourth structure portion 24 and the fifth structure portion 25 may be integrally formed, or separately formed and connected together by a connection structure (e.g., a screw, an adhesive layer, a clamping structure).

The fourth structure portion 24 has a plate shape, and is provided with a through hole K2 for allowing the third structure portion 13 of the copying camera 120 to pass through, for use as a motherboard bracket of the copying electronic apparatus 100. The fifth structure portion 25 is disposed on the fourth structure portion 24, and is used for copying a portion of the rear cover 130 of the electronic device 100, where the decoration module 110 is installed.

In some embodiments, the fifth structural portion 25 is formed by extending and protruding from a region corresponding to the decoration module 110 on the surface of the fourth structural portion 24 on the side far from the first component 10 to the side far from the first component 10, and the height of the protrusion is equal to the thickness of the rear cover 130. For some cases, the main board bracket and the rear cover 130 of the electronic device 100 are made of plastic materials, respectively, and are connected by a connecting structure. In this embodiment, the fifth structure part 25 and the fourth structure part 24, which follow both sides of the jig, are integrally formed, so that the structural design and the mounting connection can be simplified, and the jig cost can be reduced. Moreover, through testing, the stress/deformation conditions of the integrated fourth structure part 24 and the fifth structure part 25 are consistent with those of the split structure, so that the influence on the test structure is small.
