[0063] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0064] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0065] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0066] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0067] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0068] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0069] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0070] like Figures 1 to 11As shown, this embodiment provides a mobile phone key assembly positioning device 10, which is used to position the matching parts and the limiter 3000 that need to be connected, so as to ensure the relative position relationship between the main part and the matching part; wherein the main part is a mobile phone shell 1000, the mobile phone shell 1000 has a mounting cavity, and the side wall of the mobile phone shell 1000 is provided with a mounting hole extending along the first direction, the matching part is a key 2000, the key 2000 is penetrated in the mounting hole, and is partially located outside the mobile phone shell 1000, and partially located in the mounting cavity, the limiter 3000 is located in the mounting cavity, and is welded or clamped with the key 2000, and forms a whole with the key 2000, so as to prevent the key 2000 from passing through the mobile phone shell 1000 from the mounting hole. The mobile phone key assembly positioning device 10 includes a frame 100, a reference component 200, a first matching component 300 and a second matching component 400. The frame 100 has a fixing station; the reference assembly 200 is arranged on the frame 100 and includes a reference member 210, the reference member 210 includes a first reference portion 211 for abutting against the mobile phone case 1000 and a second reference portion 212 for abutting against the first end of the button 2000, and the first reference portion 211 and the second reference portion 212 are arranged at intervals along the first direction; the first matching assembly 300 is arranged on the frame 100 and includes a first matching member 310, the end of the first matching member 310 has a first matching portion 311 for abutting against the limiting member 3000, and the first matching portion 311 and the first reference portion 211 are arranged along the first direction. The first mating component 400 is arranged opposite to each other and can approach or move away from each other. When the first mating portion 311 and the first reference portion 211 approach each other, the stopper 3000 and the mobile phone shell 1000 that are in contact with each other are clamped and positioned along the first direction. The second mating component 400 is arranged on the frame 100 and includes a second mating component 410. The second mating component 410 has a second mating portion 411 for abutting against the other end of the button 2000. The second mating portion 411 and the second reference portion 212 are arranged opposite to each other along the first direction and can approach or move away from each other. When the second mating portion 411 and the second reference portion 212 approach each other, the button 2000 is clamped and positioned along the first direction. In this embodiment, the first direction is the left-right direction, that is, the width direction of the mobile phone shell 1000.

[0071] The first reference part 211 of the reference component 200 and the first matching part 311 of the first matching part 310 of the first matching component 300 are brought close to each other to complete the positioning of the mutually abutting limiting component 3000 and the mobile phone shell 1000; the second reference part 212 and the second matching part 411 of the second matching part 410 of the second matching component 400 are brought close to each other to position the button 2000, thereby ensuring the relative position relationship between the button 2000 and the mobile phone shell 1000 and eliminating the size error of the button 2000 located outside the mobile phone shell 1000. , improving the user experience; in addition, since the position and structure of the reference member 210 will not change, and the relative positions of the first reference part 211 and the second reference part 212 remain unchanged, the distance of the button 2000 extending out of the mobile phone shell 1000 remains fixed, eliminating the processing error of the button 2000 and the thickness of the side wall of the mobile phone shell 1000, ensuring the size of each button 2000 extending out of the corresponding mounting hole, ensuring that the assembly of each mobile phone shell 1000 and the button 2000 has the same accuracy, thereby ensuring the consistency of each mobile phone after assembly. Finally, the positioning of the limiter 3000 and the mobile phone shell 1000 is only achieved through the cooperation of the first reference part 211 of the reference assembly 200 and the first matching part 311 of the first matching member 310, with the help of the abutment relationship between the limiter 3000 and the mobile phone shell 1000, which not only ensures the matching accuracy between the two, but also avoids the separate positioning of the two, simplifies the positioning structure, and improves the convenience and efficiency of operation.

[0072] The interval between the first reference portion 211 and the second reference portion 212 is 0.2 mm to 3 mm. Optionally, the interval between the first reference portion 211 and the second reference portion 212 is 1 mm, 1.5 mm or 2 mm to adapt to different models of mobile phones and ensure the comfort of pressing feel.

[0073] In some embodiments, in order to facilitate welding, the stopper 3000 needs to be set to an L shape. The stopper 3000 includes a cross bar 3100 and a vertical bar 3200 connected to each other. The cross bar 3100 extends along the second direction. The side wall of the cross bar 3100 away from the vertical bar 3200 abuts against the inner side wall of the mobile phone case 1000. The vertical bar 3200 extends along the first direction. The cross bar 3100 is parallel to and abuts against the inner side wall of the installation cavity of the mobile phone case 1000. The vertical bar 3200 is arranged at intervals with the button 2000. The second matching member 410 includes a second matching body, and the second matching portion 411 is a receiving groove opened in the second matching body, and the opening of the receiving groove faces the reference member 210. The end of the vertical bar 3200 away from the cross bar 3100 can be connected to the receiving groove and abut against the bottom of the groove. The second direction is the front-to-back direction, that is, the length direction of the mobile phone case 1000. The above-mentioned arrangement makes it possible for the first matching portion 311 and the first reference portion 211 to approach each other, and the force is more stable between the limit member 3000 and the mobile phone case 1000 clamped along the first direction due to the surface contact, thereby reducing the possibility of misalignment and ensuring the reliability of welding. In addition, the arrangement of the accommodating groove can constrain the vertical rod 3200 and generate downward pressure to overcome the force generated on the limit member 3000 during the welding process, thereby preventing the vertical rod 3200 from rotating around the straight line where the weld is located during the welding process, and ensuring the welding accuracy.

[0074] Generally, the mobile phone case 1000 needs to be placed on a carrier during welding, and the mobile phone case 1000 is positioned on the carrier to improve the transfer efficiency. Since there are errors in the processing of the carrier, the mobile phone case 1000 positioned by the carrier may be tilted when it is moved to the fixing station, so that the outer side of the mobile phone case 1000 is not parallel to the first reference part 211, resulting in an angle between the first reference part 211 and the mobile phone case 1000 after the first reference part 211 and the first matching part 311 are close to each other, and the button 2000 fixed by the second reference part 212 and the second matching part 411 is also in an inclined state, resulting in the size of the button 2000 located on the outside of the mobile phone case 1000 changes, thereby affecting the user experience and the consistency of the product; when the tilt angle is too large, it even affects the yield rate.

[0075] To solve the above problems, in some embodiments, the mobile phone key assembly positioning device 10 also includes a fault-tolerant mechanism 500, which includes a fault-tolerant base 510, a first fault-tolerant component 520, a second fault-tolerant component 540, two first elastic components 530 and two second elastic components 550, wherein the first fault-tolerant component 520 is hinged to the fault-tolerant base 510 through a first hinge shaft 521 extending along the third direction; the two first elastic components 530 are both arranged between the fault-tolerant base 510 and the first fault-tolerant component 520. The first and second elastic members 530 and 550 are respectively arranged between the first and second hinge shafts 521 and are respectively arranged along the first direction on both sides of the first hinge shaft 521, so that the first fault-tolerant member 520 is stopped at the first initial position; the second fault-tolerant member 540 is hinged to the first fault-tolerant member 520 through the second hinge shaft 541 extending along the first direction, and is connected to the reference member 210; the two second elastic members 550 are respectively arranged between the first and second fault-tolerant members 520 and 540, and are respectively arranged along the third direction on both sides of the second hinge shaft 541, so that the second fault-tolerant member 540 is stopped at the second initial position. The two first elastic members 530 and the two second elastic members 550 are respectively extended along the first direction. Under the action of the four elastic members, the reference member 210 is driven to remain in the initial position when no external force is applied, that is, the reference member 210 extends along the second direction, and the planar first reference portion 211 and the planar second reference portion 212 are both perpendicular to the first direction. The above arrangement enables the reference member 210 to rotate around the second direction and the third direction under the action of four elastic members, thereby adapting to the tilt of the mobile phone case 1000 caused by the error of the carrier, ensuring that the first reference portion 211 and the mobile phone case 1000 are parallel and in surface contact to avoid the occurrence of an angle, and at the same time, the second reference portion 212 and the button 2000 are parallel and in surface contact to avoid the occurrence of an angle; thereby ensuring the dimensional accuracy of the button 2000 located on the outside of the mobile phone case 1000.

[0076] The fault-tolerant base 510 is provided with a base hole, and the first fault-tolerant member 520 has a first hinge hole 522; the first hinge shaft 521 is passed through the base hole and the first hinge hole 522. The first hinge hole 522 is a long hole, and its length direction is the first direction, so that the first fault-tolerant member 520 and the fault-tolerant base 510 can move relative to each other along the first direction.

[0077] In some embodiments, the fault-tolerant base 510 has a fault-tolerant limiting groove 511 extending along the third direction, and two first protrusions 512 are arranged opposite to each other at the notch of the fault-tolerant limiting groove 511; the second fault-tolerant member 540 has a limiting rod 542, and along the second direction, a second protrusion 543 is protruded on both sides of the limiting rod 542, and the distance between the two first protrusions 512 is less than the distance between the two second protrusions 543, so as to limit the second fault-tolerant member 540 from being away from the fault-tolerant base 510. The limiting rod 542 and the second protrusion 543 are located in the fault-tolerant limiting groove 511. Among them, the fault-tolerant base 510 is provided with a fault-tolerant cavity, which passes through the entire fault-tolerant base 510 along the second direction and passes through the fault-tolerant base 510 to the right, and the first fault-tolerant member 520 is located in the fault-tolerant cavity; and a part of the second fault-tolerant member 540 is located in the fault-tolerant cavity. The fault-tolerant limiting groove 511 passes through the upper side wall and the lower side wall of the fault-tolerant cavity. The above-mentioned arrangement enables the fault-tolerant mechanism 500 to be assembled by first installing the first fault-tolerant component 520, the second fault-tolerant component 540 and the elastic component, that is, first installing the first fault-tolerant component 520 and the first elastic component 530 to the fault-tolerant base 510, and then moving the second fault-tolerant component 540 along the third direction so that the second protrusion 543 is inserted into the fault-tolerant limit groove 511; finally, installing the compressed second elastic component 550 between the first fault-tolerant component 520 and the second fault-tolerant component 540, and after the second elastic component 550 loses its constraint and stretches, the two second protrusions 543 abut against the two first protrusions 512 to form a stable structure, and then moving to the next workstation, and passing the first hinge shaft 521 through the base hole of the fault-tolerant base 510 and the first hinge hole 522 of the first fault-tolerant component 520, and passing the second hinge shaft 541 through the second hinge hole of the first fault-tolerant component 520 and the third hinge hole of the second fault-tolerant component 540. Since the first fault-tolerant component 520 and the second fault-tolerant component 540 remain relatively fixed with the fault-tolerant base 510 under the action of the first elastic component 530 and the second elastic component 550, the transfer process avoids the need to set up additional tooling, and the stability of the transfer process can be ensured, thereby improving the convenience of assembly.
