[0063] Before any embodiments of the present 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 foregoing drawings.

[0064] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0065] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0066] In this 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, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0067] In this application, it will be understood by those skilled 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 tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. 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 an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, 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 the other element "upper" or "lower", but also be indirectly connected to the other 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, below 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 and positioning device 10 for positioning a mating part and a stopper 3000 to be connected to ensure the relative positional relationship between the main part and the mating part. The main part is a mobile phone case 1000, which has a mounting cavity. The sidewall of the mobile phone case 1000 is provided with a mounting hole extending along a first direction. The mating part is a key 2000, which is inserted into the mounting hole and is partially located outside the mobile phone case 1000 and partially located inside the mounting cavity. The stopper 3000 is located inside the mounting cavity and is welded or clamped to the key 2000, forming a single unit with the key 2000 to prevent the key 2000 from protruding from the mobile phone case 1000 through the mounting hole. The mobile phone key assembly and positioning device 10 includes a frame 100, a reference assembly 200, a first mating assembly 300, and a second mating assembly 400. Among them, the frame 100 has a fixing station; the reference component 200 is provided on the frame 100, and includes a reference part 210, the reference part 210 includes a first reference part 211 for abutting the mobile phone case 1000 and a second reference part 212 for abutting the first end of the button 2000, and along the first direction, the first reference part 211 and the second reference part 212 are arranged at intervals; the first matching component 300 is provided on the frame 100, and includes a first matching part 310, the end of the first matching part 310 has a first matching part 311 for abutting the limit part 3000, and the first matching part 311 and the first reference part 211 are arranged along the first direction. The first engaging portion 311 and the first reference portion 212 are arranged relative to each other and can move closer to or farther away from each other. When the first engaging portion 311 and the first reference portion 211 move closer to each other, they clamp and position the abutting limiter 3000 and the mobile phone case 1000 in the first direction. The second engaging component 400 is provided on the frame 100 and includes a second engaging member 410. The second engaging member 410 has a second engaging portion 411 for abutting the other end of the button 2000. The second engaging portion 411 and the second reference portion 212 are arranged relative to each other in the first direction and can move closer to or farther away from each other. When the second engaging portion 411 and the second reference portion 212 move closer to each other, they clamp and position the button 2000 in the first direction. In this embodiment, the first direction is the left-right direction, that is, the width direction of the mobile phone case 1000.

[0071] The first reference portion 211 of the reference assembly 200 and the first matching portion 311 of the first matching member 310 of the first matching assembly 300 are brought close to each other to complete the positioning of the mutually abutting limit member 3000 and the mobile phone case 1000; the second reference portion 212 and the second matching portion 411 of the second matching member 410 of the second matching assembly 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 case 1000 and eliminating the dimensional error of the button 2000 located outside the mobile phone case 1000. , improving the user experience; in addition, because the position and structure of the reference member 210 do not change, and the relative positions of the first reference portion 211 and the second reference portion 212 remain unchanged, the distance that the button 2000 extends out of the mobile phone case 1000 remains fixed, eliminating processing errors in the thickness of the button 2000 and the side wall of the mobile phone case 1000, ensuring the size of each button 2000 extending out of the corresponding mounting hole, and ensuring that the assembly of each mobile phone case 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 case 1000 is only achieved through the cooperation between the first reference portion 211 of the reference assembly 200 and the first matching portion 311 of the first matching member 310. With the help of the abutment relationship between the limiter 3000 and the mobile phone case 1000, the matching accuracy between the two is guaranteed while avoiding the need to position them separately, simplifying the positioning structure and improving operational convenience and efficiency.

[0072] The first reference portion 211 and the second reference portion 212 have a spacing of 0.2 mm to 3 mm. Optionally, the spacing of the first reference portion 211 and the second reference portion 212 is 1 mm, 1.5 mm, or 2 mm to accommodate different models of mobile phones and ensure a comfortable pressing feel.

[0073] In some embodiments, to facilitate welding, the retaining member 3000 is configured to be L-shaped. The retaining member 3000 includes a connected horizontal bar 3100 and a vertical bar 3200. The horizontal bar 3100 extends in the second direction, with the sidewall of the horizontal bar 3100 away from the vertical bar 3200 abutting the inner sidewall of the mobile phone case 1000. The vertical bar 3200 extends in the first direction, parallel to and abutting the inner sidewall of the mounting cavity of the mobile phone case 1000. The vertical bar 3200 is spaced apart from the button 2000. The second mating member 410 includes a second mating body, a second mating portion 411 being a receiving groove formed in the second mating body, the opening of the receiving groove facing the reference member 210. The end of the vertical bar 3200 away from the horizontal bar 3100 can be inserted into the receiving groove and abut against the bottom of the groove. The second direction is the front-to-back direction, i.e., 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 between the limiting member 3000 and the mobile phone case 1000 clamped along the first direction is more stable due to the surface contact, thereby reducing the occurrence 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 limiting member 3000 during the welding process, thereby avoiding 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, when welding, the mobile phone case 1000 needs to be placed on a carrier and positioned on the carrier to improve transfer efficiency. Since there may be 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 and the first reference part 211 are not parallel. As a result, after the first reference part 211 and the first matching part 311 are close to each other, there is an angle between the first reference part 211 and the mobile phone case 1000, 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 a change in the size of the button 2000 located on the outside of the mobile phone case 1000, thereby affecting the user experience and the consistency of the product; if the tilt angle is too large, it may even affect the yield rate.

[0075] To solve the above problem, in some embodiments, the mobile phone key assembly positioning device 10 further includes a fault-tolerant mechanism 500, which includes a fault-tolerant base 510, a first fault-tolerant member 520, a second fault-tolerant member 540, two first elastic members 530 and two second elastic members 550, wherein the first fault-tolerant member 520 is hinged to the fault-tolerant base 510 through a first hinge shaft 521 extending along the third direction; the two first elastic members 530 are both arranged between the fault-tolerant base 510 and the first fault-tolerant member 520. The first and second tolerant members 520 and 540 are respectively provided between the first and second tolerant members 520 and 540 and are respectively provided on both sides of the first hinge axis 521 along the first direction so that the first tolerant member 520 is stopped in the first initial position. The second tolerant member 540 is hinged to the first tolerant member 520 via the second hinge axis 541 extending along the first direction and is connected to the reference member 210. The two second elastic members 550 are both provided between the first and second tolerant members 520 and 540 and are respectively provided on both sides of the second hinge axis 541 along the third direction so that the second tolerant member 540 is stopped in the second initial position. The two first elastic members 530 and the two second elastic members 550 all extend in 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 in 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 the 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 part 211 and the mobile phone case 1000 are parallel and in surface contact, avoiding the formation of an angle. At the same time, the second reference part 212 and the button 2000 are parallel and in surface contact, avoiding the formation 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 has a base hole, and the first fault-tolerant member 520 has a first hinge hole 522. The first hinge shaft 521 is disposed through the base hole and the first hinge hole 522. The first hinge hole 522 is an elongated hole with its length oriented in a first direction, thereby enabling the first fault-tolerant member 520 and the fault-tolerant base 510 to 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, with two first protrusions 512 positioned opposite each other at the groove opening of the fault-tolerant limiting groove 511. The second fault-tolerant component 540 has a limiting rod 542, with a second protrusion 543 protruding from each side of the limiting rod 542 along the second direction. The distance between the two first protrusions 512 is smaller than the distance between the two second protrusions 543, thereby restricting the second fault-tolerant component 540 from moving away from the fault-tolerant base 510. The limiting rod 542 and the second protrusion 543 are positioned within the fault-tolerant limiting groove 511. The fault-tolerant base 510 is provided with a fault-tolerant cavity, which extends through the entire fault-tolerant base 510 along the second direction and extends rightward through the fault-tolerant base 510. The first fault-tolerant component 520 is positioned within the cavity, and a portion of the second fault-tolerant component 540 is positioned within the cavity. The fault-tolerant limiting groove 511 extends through both the upper and lower sidewalls of the cavity. The above-mentioned arrangement enables the assembly process of the fault-tolerant mechanism 500 to first install the first fault-tolerant part 520, the second fault-tolerant part 540 and the elastic part, that is, first install the first fault-tolerant part 520 and the first elastic part 530 to the fault-tolerant base 510, and then move the second fault-tolerant part 540 along the third direction so that the second protrusion 543 is inserted into the fault-tolerant limit groove 511; finally, install the compressed second elastic part 550 between the first fault-tolerant part 520 and the second fault-tolerant part 540, after the second elastic part 550 loses its constraint and stretches, and the two second protrusions 543 abut against the two first protrusions 512 to form a stable structure, and then move to the next workstation, and pass 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 part 520, and pass the second hinge shaft 541 through the second hinge hole of the first fault-tolerant part 520 and the third hinge hole of the second fault-tolerant part 540. Since the first fault-tolerant part 520 and the second fault-tolerant part 540 remain relatively fixed with the fault-tolerant base 510 under the action of the first elastic part 530 and the second elastic part 550, the transfer process avoids the need for additional tooling, ensures the stability of the transfer process, and improves the convenience of assembly.

[0078] Furthermore, the fault-tolerant base 510 has a fault-tolerant reference surface 513; the second fault-tolerant member 540 is provided with a limit surface 544. The limit surface 544 and the fault-tolerant reference surface 513 are arranged opposite each other and can abut each other to limit the relative rotation limit position of the second fault-tolerant member 540 and the first fault-tolerant member 520, and to limit the relative rotation limit position between the first fault-tolerant member 520 and the fault-tolerant base 510. The fault-tolerant reference surface 513 is formed at the end of the fault-tolerant base 510 facing the second fault-tolerant member 540; the second fault-tolerant member 540 includes a fault-tolerant body, and a limit rod 542 is provided on the limit surface 544 of the fault-tolerant body.

[0079] In some embodiments, the reference member 210 includes a block-shaped reference body 213. One side of the reference body 213 protrudes in a first direction to form a first protrusion. The first reference portion 211 is the end face of the first protrusion away from the reference body 213. Another side of the reference body 213 protrudes in the first direction to form a second protrusion. The second reference portion 212 is the end face of the second protrusion away from the reference body 213. During processing, only the distance between the two end faces needs to be maintained to ensure that the relative positions of the button 2000 and the mobile phone case 1000 assembled using this device remain consistent, reducing the processing difficulty.

[0080] To ensure support stability, there are two first protrusions, spaced apart along the second direction; there are two second protrusions, spaced apart along the second direction. Considering the positional relationship between the phone case 1000 and the button 2000, the two second protrusions are located between the two first protrusions along the second direction.

[0081] In some embodiments, the reference member 210 may be injection molded, and the second protrusion may be cylindrical to facilitate processing.

[0082] Different models of mobile phones have different positions of the button 2000 relative to the phone case 1000, that is, different positions of the mounting holes. To this end, the reference assembly 200 further includes a reference driver 230 and a plurality of fine-tuning assemblies 220. The fine-tuning assemblies 220 are sequentially connected between the reference driver 230 and the reference member 210. The fine-tuning assemblies 220 are used to adjust the initial position of the reference member 210. Specifically, the fine-tuning assemblies 220 are used to adjust the initial position of the reference member 210 along the second direction and the third direction.

[0083] The structure of the fine adjustment component 220 can adopt the micrometer fine adjustment mechanism in the prior art. The specific structure and use method of the micrometer fine adjustment mechanism are well known to those skilled in the art and will not be described in detail here.

[0084] The reference assembly 200 further includes a reference driving member 230 and a reference matching elastic member 240. The reference matching elastic member 240 is disposed between the reference driving member 230 and the reference member 210 to apply an elastic force to the reference member 210. Specifically, the reference driving member 230 is disposed on the frame 100, and an output end is connected to a first adapter 251. The first adapter 251 is connected to a fixing seat of one fine-tuning assembly 220. The adjusting member of the fine-tuning assembly 220 is connected to a second adapter 252. The second adapter 252 is connected to a fixing seat of another fine-tuning assembly 220. The adjusting member of the other fine-tuning assembly 220 is connected to a third adapter 253. The reference member 210 is slidably disposed on the third adapter 253 via a slide rail and a slider. The reference matching elastic member 240 is disposed between the third adapter 253 and the reference member 210. The third adapter 253 includes a sliding portion 2532 and an abutting portion 2531 connected to each other. The slide rail is disposed on the sliding portion 2532 . The reference matching elastic member 240 is disposed between the abutting portion 2531 and the reference member 210 .

[0085] The first mating assembly 300 further includes a first driving member and a first mating elastic member. The connection method of the first driving member and the first mating elastic member can be roughly similar to that of the reference assembly 200. The first mating assembly 300 does not need to be provided with the fault tolerance mechanism 500, which saves costs while ensuring the relative position of the button 2000 and the mobile phone case 1000.

[0086] The second mating assembly 400 further includes a second driving member and a second mating elastic member, and the connection method of the second driving member and the second mating elastic member can be roughly arranged with reference to the reference assembly 200. The second mating assembly 400 does not need to be provided with the fault tolerance mechanism 500, which saves costs while ensuring the relative position of the button 2000 and the mobile phone case 1000.

[0087] The mobile phone key assembly and positioning device 10 also includes a third matching component 420, which is arranged on the frame 100 and includes a third matching part 421. The third matching part 421 can move along the third direction. The third matching part 421 can move downward to simultaneously pressurize part of the key 2000 and part of the limiter 3000 or move upward to avoid the key 2000 and the limiter 3000 transmitted along the second direction, thereby making the welding process more stable and ensuring the welding accuracy between the two. Among them, when pressing, the welding point between the two is avoided. The third matching component 420 also includes a third drive component. The third drive component component is arranged on the frame 100, and the output end is transmission-connected to the third matching part 421 to drive the third matching part 421 to move along the third direction.

[0088] This embodiment also provides a welding device, which is used to weld the button 2000 and the limiter 3000 to constrain the relative position relationship between the button 2000 and the mobile phone case 1000; the welding device includes a welding assembly 600 and the mobile phone button assembly and positioning device 10 in any of the above embodiments; the welding assembly 600 includes a welding head, which can be close to or away from the fixing station, and when close to the fixing station, it can weld the limiter 3000 and the button 2000 located at the fixing station.

[0089] In some embodiments, the welding apparatus further includes a transmission assembly 700 for moving a carrier carrying the mobile phone case 1000, the button 2000, and the stopper 3000 from the loading station to the fixing station. The transmission assembly may be a transmission belt, which is driven by a driving wheel and a driven wheel to move the transmission belt, thereby driving the carrier to move.

[0090] In some embodiments, the frame 100 further includes a detection station, and the welding device further includes a detection component 800 to detect the relative position of the button 2000 and the mobile phone shell 1000. The detection component 800 includes a camera, which is used to photograph the weld to determine the welding effect.

[0091] Since the welding time is longer than the detection time, in order to improve production efficiency, in some embodiments, the welding equipment has two welding components 600 and two mobile phone key assembly positioning devices 10, and the two welding components 600 correspond to one detection component 800.

[0092] This embodiment also provides a welding method, which is applied to the above-mentioned welding equipment, and the method includes the following steps:

[0093] The button 2000 is placed in the mounting hole of the mobile phone case 1000, and the limiting member 3000 is placed in the accommodating cavity.

[0094] The first reference portion 211 of the reference member 210 and the first matching portion 311 of the first matching member 310 cooperate with each other to complete the abutment and positioning of the mobile phone case 1000 and the limiting member 3000.

[0095] The second reference portion 212 of the reference member 210 and the second matching portion 411 of the second matching member 410 cooperate with each other to complete the positioning of the key 2000 .

[0096] The welding part is moved to the fixing station and the limiting part 3000 and the button 2000 are welded.

[0097] The above method can ensure that the button 2000 extends out of the mobile phone case 1000 and is not affected by processing accuracy errors, thereby improving user experience and ensuring consistency of each mobile phone after assembly.

[0098] Furthermore, the welding equipment also includes a third mating component 420. The third mating part 421 in the third mating component 420 is pressed against the button 2000 and the limit part 3000 before welding, thereby avoiding relative movement between the two during the welding process and improving welding accuracy.

[0099] The conveyor assembly 700 transports multiple carriers at a time, wherein the products in two adjacent carriers are welded simultaneously. When welding is completed, the two carriers carrying the two welded components are moved to the inspection station in sequence.

[0100] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
