Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Today, the appearance design and the visual effect design of a battery cover are indispensable parts in the design of a mobile terminal when the mobile terminal is required to be dazzled. The shape and texture of battery covers are becoming more and more diverse, for example, glass battery covers, full-face battery covers, have appeared in isolation. The manufacture and measurement of glass cell covers and full arc cell covers is becoming increasingly challenging. For the terminal, a battery cover qualified in manufacture can be completely attached to the whole machine, so that a good adaptive effect is formed. Therefore, it is very important to control the quality of the cell cover, and the curved surface fit and the curved surface control are important and difficult in the measurement process of the cell cover. For the battery cover with a plane in the middle, a plane jig can be used for supporting and pressing, but the method is only suitable for the design of the battery cover with the plane, and the influence of product deformation on the outline and the size is influenced due to the fixation, and if secondary correction cannot be performed in the subsequent assembly process, the measurement result is not matched with the adaptation effect of the whole machine. In some cases, the placement imbalance affects the measurement of the stretch height and profile, and even the entire outer profile, more heavily affected by process dimensional variations. At present, no plane measuring reference which can be referred to is available for a full-arc battery cover, and generally, the pressure of measuring equipment affects the accuracy of data such as height and the like.

In view of the above technical problems, the present disclosure provides a positioning fixture, fig. 1 is a structural diagram of a cross section of a positioning fixture according to an exemplary embodiment, as shown in fig. 1, the positioning fixture of the present disclosure includes a fixture body 100, which is provided with a placing area 110, where the placing area 110 is used for placing an object 10 to be positioned; the supporting columns 200 are arranged in the placing area 110 and protrude out of the surface of the jig body 100; wherein, an absorption hole 210 is arranged in the support column 200 for absorbing the object 10 to be positioned.

In an exemplary embodiment of the present disclosure, the object 10 to be positioned may be a battery cover, a housing, a cover plate, and the like of the terminal in general. The surface of the object to be positioned 10 is an all-arc surface, for example, a battery cover which can be an all-arc surface, and the battery cover can be made of metal or glass. The object 10 to be positioned of the present disclosure is a component for a terminal, and the surface of the object 10 to be positioned of the present disclosure is a part of the outer surface of the terminal, that is, a surface of the object to be positioned which is in direct contact with a user, and in the embodiment of the present disclosure, the surface of the object 10 to be positioned is a surface of the object opposite to the surface of the jig body 100, that is, a surface of the object 10 to be positioned which is in contact with the support column 200.

In the exemplary embodiment of the present disclosure, the fixture body 100 may be a plane or a curved surface, and may be set according to the setting requirement of the object 10 to be positioned or the application specificity of the positioning fixture. The placing area 110 on the jig body 100 is used for placing the object 10 to be positioned. The placement area 110 of the present disclosure is not particularly limited to a planar through-space, and specifically may be adapted to the shape of the object 10 to be positioned. For example, when the outer shape of the object 10 to be positioned is a planar structure, the placement region 110 may be a plane, and when the outer shape of the object 10 to be positioned is a three-dimensional structure, the placement region 110 may be a three-dimensional structure.

In the exemplary embodiment of the present disclosure, the supporting columns 200 are disposed to protrude from the surface of the jig body 100, that is, the surface of the supporting columns 200 is higher than the surface of the jig body 100 in the thickness direction of the jig body 100. The object 10 to be positioned can be supported on the surface of the jig body 100 by the arrangement, so that the surface of the object 10 to be positioned in the full arc surface is completely exposed on the jig body 100, and subsequent measurement work can be facilitated. In the present disclosure, the specific height of the supporting column 200 protruding from the surface of the fixture body 100 is not limited, and may be specifically set according to the actual positioning requirement.

In the exemplary embodiment of the present disclosure, the supporting column 200 may be fixed to the jig body 100, or may be movably disposed on the jig body 100. For example, the supporting column 200 may be telescopic, and when the supporting column 200 is used to position the object 10 to be positioned in the full arc plane, the supporting column 200 may be extended to protrude from the surface of the jig body 100. When the positioning jig is used for positioning the object 10 to be positioned in a planar structure, the supporting column 200 may not extend out, so that the positioning jig can be flexibly arranged, and is suitable for the objects 10 to be positioned with various profiles.

In the exemplary embodiment of the present disclosure, the inside of the support column 200 is provided with an adsorption hole 210 for adsorbing the object 10 to be positioned. The positioning jig can be further provided with an air suction component which is communicated with the adsorption hole 210 to complete the air suction effect. The mode of fixing the object 10 to be positioned by sucking through the adsorption hole 210 can specifically set the sucking force according to the material or shape of the object 10 to be positioned, and avoids damaging the outline shape of the object 10 to be positioned while adsorbing the object 10 to be positioned. For example, when the object 10 to be positioned is made of glass, the air suction force can be adaptively reduced, and when the object 10 to be positioned is made of a material which is relatively firm and is not suitable for deformation, such as metal, the air suction force can be increased in a proper amount.

In the exemplary embodiment of the present disclosure, the suction hole 210 may be disposed not to penetrate through the jig body 100, and may also be disposed to penetrate through the jig body 100. Fig. 2 is a structural view illustrating a cross-section of a positioning jig according to another exemplary embodiment, and as shown in fig. 2, the suction holes 210 may be disposed to penetrate the jig body 100, which may facilitate disposing the suction member below the jig body 100.

In the exemplary embodiment of the present disclosure, the supporting columns 200 may be provided in plural, and the plural supporting columns 200 are symmetrically provided along the center line 115 of the placement area 110. Fig. 3 is a top view of a positioning fixture according to an exemplary embodiment, and as shown in fig. 3, a plurality of support columns 200 may be provided, and a plurality of support columns may be symmetrically provided along the center line 115 of the placement area 110, for example, four support columns may be provided. In the present disclosure, the support columns 200 may include a first support column 201, a second support column 202, a third support column 203, and a fourth support column 204. The first support column 201 and the second support column 202 are symmetrically arranged along the center line 115 of the placement area 110; the third support column 203 and the fourth support column 204 are symmetrically arranged along the center line 115 of the placement area 110; the line connecting the first support column 201 and the third support column 203 is parallel to the center line 115, and the line connecting the second support column 202 and the fourth support column 204 is parallel to the center line 115.

In the exemplary embodiment of the present disclosure, taking a rectangular terminal such as a mobile phone or a tablet computer as an example, when the positioning fixture of the present disclosure is used for positioning a housing of a rectangular terminal such as a mobile phone or a tablet computer, correspondingly, the placement area 110 is a rectangle, and a center line of the placement area 110 may be a center line of a long side of the rectangle, and may also be a center line of a short side of the rectangle. In the embodiments of the present disclosure, the center line of the long side of the rectangle is taken as an example for explanation. The first supporting column 201 and the second supporting column 202 are symmetrically arranged along the central line 115 of the placement area 110, and the third supporting column 203 and the fourth supporting column 204 are symmetrically arranged along the central line 115 of the placement area 110, so that the suction force provided by the suction holes 210 can be uniformly applied to the surface of the object 10 to be positioned, and the contour of the object 10 to be positioned cannot be changed due to uneven force application while the object 10 to be positioned is fixed.

In the exemplary embodiment of the present disclosure, a connection line between the first supporting column 201 and the third supporting column 203 may also be located at a middle position from the edge of the placement area 110 to the center line 115, and a connection line between the second supporting column 202 and the fourth supporting column 204 may also be located at a middle position from the edge of the placement area 110 to the center line 115. That is, the line connecting the first support column 201 and the third support column 203 is located at a position of a quarter length of the side of the placement area 110 intersecting the line. The line connecting the second support column 202 and the fourth support column 204 is located at a position of a quarter length of the side of the placement area 110 intersecting the line. This arrangement enables the four support columns 200 to be distributed so that the four support columns 200 surround a rectangle, which becomes the center of the placement area 110. This rectangle may also be the center of the surface of the object to be positioned 10 when the object to be positioned 10 corresponds to the configuration of the placement area 110. That is, the suction force of the suction holes 210 of the four support columns 200 is applied to the center of the object to be positioned 10, so that it is possible to provide a suitable suction force to the object to be positioned 10 to effectively fix the object to be positioned.

The utility model discloses a positioning jig is provided with the support column that has the absorption hole through placing the region, will be positioned the object through the support column and support in the surface of tool body to, the absorption through the absorption hole will be positioned the object and adsorb fixedly, such setting can be applicable to the object of being positioned of full cambered surface, when fixing the object of being positioned, can avoid influencing the appearance profile of the object of being positioned and lead to the object of being positioned to warp, and then can guarantee that the measured data of treating the object of being positioned is accurate.

As shown in fig. 3, the positioning fixture of the present disclosure further includes a limiting component, which is disposed around the placement area and used for limiting the placement area 110. That is, the limiting component is used for limiting the plane area of the placing area 110, and when the object 10 to be positioned is correspondingly placed into the placing area 110, the limiting component can also be used for limiting the displacement of the object 10 to be positioned on the plane. For example, in the exemplary embodiment of the present disclosure, in the thickness direction of the jig body 100, the height of the position limiting part is greater than the thickness of the object 10 to be positioned. That is, by setting the height of the position-limiting component higher than the object 10 to be positioned, the auxiliary supporting column 200 can further limit the object 10 to be positioned in the placement region 110, which facilitates stable placement of the object 10 to be positioned.

In an exemplary embodiment of the present disclosure, the stopper member includes a first stopper member 310 and a second stopper member 320; the first limiting part is arranged on the first edge 111 of the placing area 110; the second limiting member 320 is disposed on the second side 112 of the placement area. The first stopper member 310 may be provided in plurality, and may be two, for example. The second stopper member 320 may be provided in plural, for example, two. The plurality of first and second limiting members 310 and 320 may more firmly limit the object 10 to be positioned.

In the exemplary embodiment of the present disclosure, the extending direction of the first stopper member 310 is perpendicular to the extending direction of the second stopper member 320. The first stopper member 310 is located at the first side 111 of the placement region 110 to define the range of the placement region 110, and the extending direction of the first stopper member 310 may be defined as the extending direction of the first side 111 of the placement region 110 in the present disclosure. Accordingly, the extending direction of the second stopper member 320 may be defined as the extending direction of the second side 112. When the placement area 110 is rectangular, the first side 111 and the second side 112 of the placement area 110 are perpendicular to each other, and accordingly, the extending direction of the first stopper member 310 disposed on the first side 111 is perpendicular to the extending direction of the second stopper member 320.

As shown in fig. 1 and 3, in the exemplary embodiment of the present disclosure, the position-limiting component 300 may further include a third position-limiting component 330, wherein the third position-limiting component 330 includes a first surface 331 and a second surface 332 which intersect with each other; the first surface 331 and the first stopper 310 are disposed opposite to each other in the longitudinal direction of the jig body 100, and the second surface 332 and the second stopper 320 are disposed opposite to each other in the width direction of the jig body 100.

In the embodiment of the present disclosure, when the placement area 110 is rectangular, the placement area may further include a third side 113 and a fourth side 114, and the first side 111 and the second side 112. The third position limiting member 330 may be disposed at a crossing position of the third side 113 and the fourth side 114, for example, the first surface 331 of the third position limiting member 330 may be located at the third side 113, and the second surface 332 of the third position limiting member 330 may be located at the fourth side 114. In this arrangement, the third stopper member 330 may be formed at a position opposite to a position where the first stopper member 310 intersects with the extending direction of the second stopper member 320, that is, after the first stopper member 310 and the second stopper member 320 define the range of the placement region 110 on the two intersecting sides of the placement region 110, respectively, the third stopper member 330 may further define the range of the placement region 110 on the third side 113 and the fourth side 114.

In an exemplary embodiment of the present disclosure, the third limiting member 330 may be configured to slide relative to the jig body 100 for fastening the object 10 to be positioned to the placing region 110. The third limiting part 330 is configured to be slidable, and after the object 10 to be positioned is placed in the placement area, the third limiting part 330 is slid to apply a certain acting force to the object 10 to be positioned in the direction of the object 10 to be positioned, so that the object 10 to be positioned is more fittingly placed in the placement area 110.

In general, the layout of the positioning jig may be set according to a design drawing of the object 10 to be positioned, for example, the distance between the limiting component and the four support columns may be set to be + tolerance/2 of the median of the product external dimensions of the design drawing. For different objects 10 to be positioned, the design of the positioning jig should be adjusted according to the design value of the manufacturing process because the sizes of the products are different.

The pressure of the probe 400 can be set to be different for different objects 10 to be positioned, for example, when the pressure of the probe 400 is adjusted to be 0.2g at the minimum for a glass battery cover plate, so that deformation caused by the pressure in the measurement process is avoided, and the accuracy of the measurement result is ensured.

In the exemplary embodiment of the present disclosure, the probe 400 may be used to respectively detect the long and short edges of the object 10 to be positioned and find 4 coplanar points, and then the 3D matching level of the surfaces and the product is corrected, thereby defining the datum point and the measurement coordinate system of the product stretching height.
