[0002] With the development of technology, a variety of unlocking methods for electronic devices have emerged, such as face unlocking, password unlocking and fingerprint unlocking.

[0003] Fingerprint unlocking is a biometric technology that allows users to unlock electronic devices using their registered fingerprint information. Fingerprint unlocking includes rear fingerprint unlocking, under-screen fingerprint unlocking, and side button fingerprint unlocking.

[0004] Under-screen fingerprint unlocking requires the user to look at the screen of the electronic device, find the fingerprint position and touch it to unlock, which takes a long time to unlock and is not convenient to use. Rear-mounted fingerprint unlocking, on the other hand, sets a groove on the housing where the fingerprint is set. The user does not need to look at the groove position, but can unlock the device by groping and touching the groove with their finger, which is convenient to use. The rear-mounted fingerprint is designed on the back of the electronic device, which can ensure the integrity of the electronic device's screen and realize a true full-screen.

[0045] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0046] In related technology, one end of the fingerprint module in a rear-mounted fingerprint scanner is connected to the electronic device's motherboard via a board-to-board connector (BTB). The rear camera's bracket is assembled to the midframe, and foam is placed at the corresponding position of the bracket to hold the connector down and prevent it from loosening. The other end of the fingerprint module is manually assembled to the housing. This assembly method is difficult to operate and has low assembly efficiency. The accuracy of the appearance after assembly cannot be guaranteed. Neither the fingerprint module nor the housing has a positioning structure. Manual assembly cannot guarantee the positional accuracy after assembly, reducing the production yield of rear-mounted fingerprint scanners.

[0047] The present disclosure provides a fingerprint module installation device. The fingerprint module installation device includes a first supporting assembly and a second supporting assembly. The second supporting assembly is used to support a half-mold assembly on which the fingerprint module is installed. The first supporting assembly is used to support a housing connected to the fingerprint module. Under the action of an external force, the first supporting assembly slides horizontally relative to the second supporting assembly to cause the first supporting assembly and the second supporting assembly to be offset or aligned. The installation device includes a suction portion and a first driving portion. The suction portion is mounted on the first driving portion, which is mounted on the first supporting assembly. The suction portion is configured to absorb the free end of the fingerprint module. In the driven state, the first driving portion drives the free end to move to a predetermined area of ​​the first supporting assembly via the suction portion. When the housing is placed on the first supporting assembly, it covers the free end. The first driving portion drives the suction portion to move relative to the housing, applying pressure to the housing via the suction portion to cause the free end to adhere to the housing. The installation device of the present disclosure uses the first driving portion and the suction portion to install the free end of the fingerprint module in the predetermined area, achieving automated assembly, reducing reliance on manual operation, improving assembly accuracy, increasing production efficiency, and reducing production costs.

[0048] In an exemplary embodiment, Figure 1 、 Figure 5 As shown, a fingerprint module installation device is used to assemble a fingerprint module 32 to a housing 33 of an electronic device 3. The electronic device 3 can be, for example, a mobile phone or tablet computer. The housing 33 is, for example, the back cover of the electronic device 3. The fingerprint module 32 is assembled to the housing 33 of the electronic device, thus realizing a rear-mounted fingerprint design for the electronic device 3. The electronic device 3 includes a mold half assembly 31, a fingerprint module 32, and a housing 33. The mold half assembly 31 includes, for example, a motherboard and a midframe. The fixed end of the fingerprint module 32 is fastened to the motherboard via a connector, and the free end 321 of the fingerprint module 32 is connected to the housing 33.

[0049] In this embodiment, if Figure 1As shown, the fingerprint module installation device includes a first supporting component 1 and a second supporting component 2, the second supporting component 2 is used to support the half mold component 31 installed with the fingerprint module 32, and the first supporting component 1 is used to support the housing 33 connected to the fingerprint module 32. Figure 1 The first bearing assembly 1 is located above the second bearing assembly 2. Under the action of external force, the first bearing assembly 1 can move horizontally (refer to Figure 1 The first and second supporting assemblies 1 and 2 are slid relative to each other (in the X-axis direction shown) to stagger or align the first and second supporting assemblies 1 and 2, and thus to stagger or align the housing 33 and the mold half 31. In the staggered state, the second supporting assembly 2 is exposed, facilitating placement of the mold half 31 within the first supporting assembly 1. In the aligned state, the mold half 31 and the housing 33 are aligned vertically, facilitating assembly of the fingerprint module 32 to the housing 33.

[0050] In this embodiment, if Figure 1 、 Figure 5 As shown, the installation device of the fingerprint module includes an adsorption part 4 and a first driving part 5. The adsorption part 4 is installed on the first driving part 5, and the first driving part 5 is installed on the first supporting component 1. The adsorption part 4 is configured to absorb the free end 321 of the fingerprint module 32. In the driving state, the first driving part 5 drives the free end 321 to move to a predetermined area of ​​the first supporting component 1 through the adsorption part 4, and puts down the free end 321, thereby realizing the preliminary positioning of mechanical automation and further ensuring the assembly accuracy of the fingerprint module 32.

[0051] The first driving unit 5 is reset to move away from the first supporting assembly 1 to avoid blocking the first supporting assembly 1. The housing 33 is placed on the first supporting assembly 1 to achieve the positioning of the housing 33. The housing 33 will cover the free end 321 in a aligned manner, ensuring the positional accuracy of the housing 33 and the free end 321.

[0052] In the driving state, the first driving part 5 drives the adsorption part 4 to move relative to the shell 33, approaching the shell 33, and applies pressure to the shell 33 through the adsorption part 4. The surface of the free end 321 close to the shell 33 is provided with adhesive. When pressure is applied, the adhesive is activated by cold pressure, so that the free end 321 is attached to the shell 33, completing the assembly.

[0053] In an exemplary embodiment, Figure 1 、 Figure 3 、 Figure 5As shown, the adsorption portion 4 includes a press-fit body 41 and a first magnetic body 42. The first magnetic body 42 can be, for example, an electromagnet, which has a good suction force to facilitate the attraction of the free end portion 321 and avoid damage to the free end portion 321. The press-fit body 41 can be, for example, ring-shaped and compatible with the free end portion 321. The press-fit body 41 is used to apply pressure to the housing 33, pressing and activating the adhesive on the free end portion 321 and the housing 33, thereby bonding the free end portion 321 to the housing 33.

[0054] The first end of the pressing body 41 is fixedly connected to the first driving part 5, which improves the reliability of the connection between the pressing body 41 and the first driving part 5 and prevents the pressing body 41 from falling off when pressure is applied to the shell 33, thereby affecting the pressing effect.

[0055] The second end of the press-fit body 41 is provided with a groove 411, into which the first magnetic body 42 is embedded. The first magnetic body 42 and the groove 411 have an interference fit, forming a locking connection between the first magnetic body 42 and the groove 411, thereby improving the stability of the first magnetic body 42 during installation. The surface of the first magnetic body 42 is lower than the edge of the groove 411, protecting the first magnetic body 42 from damage due to compression.

[0056] In this embodiment, if Figure 1 、 Figure 3 As shown, the fingerprint module mounting device also includes a first sensing portion 43, which is disposed on the press-fit body 41. The first sensing portion 43 is fixedly connected to the outer peripheral sidewall of the press-fit body 41, for example, to prevent the press-fit body 41 from squeezing the first sensing portion 43 and causing damage to the first sensing portion 43. The first sensing portion 43 is configured to sense the placement of the housing 33 to facilitate confirmation of whether the housing 33 is placed on the first supporting assembly 1.

[0057] The first sensing part 43 can be connected to the first driving part 5 for communication. When the first sensing part 43 senses the presence of the shell 33 on the first supporting component 1, it can generate and send an indication signal to the first driving part 5 so that the first driving part 5 drives the adsorption part 4 to move.

[0058] In one example, the first sensing portion 43 is, for example, a Hall sensor, which determines whether the housing 33 is placed on the first supporting assembly 1 through changes in the magnetic field.

[0059] In another example, the first sensing portion 43 may be a piezoelectric sensor. The transmitter in the piezoelectric sensor emits a light beam, which is reflected by the housing 33. The receiver receives the reflected light and detects changes in the amount of the returned light, thereby detecting the housing 33 and confirming whether the housing 33 is placed on the first supporting assembly 1. The light beam may be visible light, infrared light, LED, or laser.

[0060] Of course, it is understandable that the first sensing part 43 is not limited to the Hall sensor and the piezoelectric sensor. The above examples are only used to explain this embodiment and do not constitute a limitation to this application. The first sensing part 43 can also be an ultrasonic sensor, etc.

[0061] In this embodiment, if Figure 1 、 Figure 3 As shown, the first driving unit 5 includes a first driving body 51 and a support body 52. ​​The first driving body 51 is, for example, a driving cylinder. The first end of the first driving body 51 is fixedly connected to the press-fit body 41, that is, the piston end of the first driving body 51 is fixedly connected to the press-fit body 41, so as to drive the press-fit body 41 to move. The second end of the first driving body 51 is fixedly connected to the support body 52, that is, the cylinder of the first driving body 51 is fixedly connected to the support body 52, thereby improving the reliability of the connection between the first driving body 51 and the support body 52.

[0062] The support body 52 is mounted on the first bearing assembly 1, enabling the first driving unit 5 to move synchronously with the first bearing assembly 1. The support body 52 includes a connecting horizontal plate 521 and two supporting vertical plates 522. The upper ends of the two supporting vertical plates 522 are fixedly connected by the connecting horizontal plate 521, and the lower ends of the two supporting vertical plates 522 are fixedly connected to the first bearing assembly 1. The first driving unit 51 is placed vertically to facilitate vertical movement of its piston end. The cylinder of the first driving unit 51 is fixedly connected to the connecting horizontal plate 521.

[0063] The side wall of the supporting vertical plate 522 is provided with an armrest 5221 to provide a force application position for workers, so that the workers can carry the installation device of the fingerprint module more easily.

[0064] In this embodiment, if Figure 1 、 Figure 3 、 Figure 5 As shown, the fingerprint module installation device further includes an image acquisition unit 6 installed on the first driving body 51 , and the image acquisition unit 6 is configured to acquire image information of a predetermined area.

[0065] The image acquisition unit 6 includes, for example, a camera 61 and a camera bracket 62. The camera 61 is fixedly connected to the first driving body 51 via the camera bracket 62. The camera 61 captures image information of a predetermined area to confirm whether the free end portion 321 is properly installed. If the free end portion 321 is not properly installed, the first driving body 51 drives the suction unit 4 to absorb the free end portion 321 and reposition it to the predetermined position. The camera 61 then continues to capture image information within the predetermined area, reconfirming whether the free end portion 321 is properly installed. The camera 61 automatically identifies the installation position of the free end portion 321, thereby automatically positioning the free end portion 321 and improving accuracy after assembly.

[0066] In this embodiment, if Figure 1 As shown, the fingerprint module mounting device further includes a second sensing portion 7, which is disposed on the support body 52 and configured to sense foreign objects within a preset range. For example, the foreign object may be a human limb, so as to confirm whether a worker's hand or arm is within the preset range.

[0067] The second sensing unit 7 can be, for example, a safety light barrier, which acts as a sensor. The second sensing unit 7 can be in communication with the first drive unit 5. If a foreign object is present, indicating that the housing 33 is not fully placed or the worker's hand is not out of the preset range, which would interfere with the operation of the first drive unit 5, a corresponding instruction is generated to the first drive unit 5, instructing it not to operate. If the foreign object is absent, indicating that pressure can be applied to the housing 33, a corresponding instruction is generated to the first drive unit 5, which then drives the suction unit 4 to apply pressure to the housing 33.

[0068] The first sensing part 43 and the second sensing part 7 respectively sense the housing 33 and foreign objects within a preset range, further ensuring that the application step of the first driving part 5 is carried out smoothly and the normal operation of the production line is ensured.

[0069] In an exemplary embodiment, Figure 1 、 Figure 2 、 Figure 5 As shown, the first supporting assembly 1 includes a first supporting body 11 and a first slot 12 formed in the first supporting body 11, with the housing 33 placed in the first slot 12. The first slot 12 is recessed in the upper surface of the first supporting body 11, and a through hole 121 is formed in the bottom wall of the first slot 12, so that the free end portion 321 can pass through the through hole 121 and be placed in a predetermined area, ensuring smooth assembly of the free end portion 321.

[0070] The depth of the first groove 12 is adapted to the thickness of the shell 33 , so that the first groove 12 can limit the shell 33 , further ensuring the alignment effect between the shell 33 and the free end 321 , and improving the accuracy after assembly.

[0071] A supporting boss 122 is further provided on the bottom wall of the first tank body 12 . The supporting boss 122 is used to support the shell 33 to prevent the shell 33 from collapsing when pressure is applied to the shell 33 .

[0072] The predetermined area is located at the supporting boss 122 of the first carrier body 11 , ensuring smooth cold press activation, and the image acquisition unit 6 can clearly acquire image information within the predetermined area.

[0073] In this embodiment, if Figure 1 、 Figure 2 、 Figure 5 As shown, the first support assembly 1 further includes a second magnetic body 13 and an annular protrusion 14. The second magnetic body 13 can be, for example, an electromagnet, to attract the free end portion 321 and ensure that the free end portion 321 is not misaligned when placed within the predetermined area. The annular protrusion 14 has a diameter that matches the diameter of the press-fit body 41 to prevent the press-fit body 41 from affecting the pressure effect.

[0074] The annular projection 14 is positioned within a predetermined area, and the second magnetic body 13 is embedded within the annular projection 14. The second magnetic body 13 and the annular projection 14 have an interference fit, allowing the second magnetic body 13 to engage with the annular projection 14, thereby enhancing the stability of the second magnetic body 13 during installation. The surface of the second magnetic body 13 is lower than that of the annular projection 14, providing protection for the second magnetic body 13 and preventing damage to the second magnetic body 13 due to compression.

[0075] In this embodiment, if Figure 1 、 Figure 2 、 Figure 5 As shown, the first bearing assembly 1 further includes a first positioning portion 15, which is disposed radially outside the annular protrusion 14. The free end portion 321 is provided with a second positioning portion 3211, and the free end portion 321 is positioned and connected to the first positioning portion 15 via the second positioning portion 3211.

[0076] In one example, the first positioning portion 15 includes at least one positioning column, and the second positioning portion 3211 includes at least one positioning hole. The positioning column and the positioning hole correspond one to one and are plug-connected, thereby realizing the positioning installation of the free end portion 321 and avoiding the misalignment of the free end portion 321, which affects the assembly accuracy.

[0077] The first positioning portion 15 can be two positioning columns, and the second positioning portion 3211 can be two positioning holes. When the positioning columns and the positioning holes are plugged in correspondingly, the first direction of the free end portion 321 (refer to Figure 1 X-axis direction shown) and the second direction (refer to Figure 1 The second magnetic body 13 can limit the free end portion 321 in the vertical direction when it attracts the free end portion 321, thereby preventing the free end portion 321 from moving in the vertical direction.

[0078] The free end portion 321 includes a body 3212 and at least one first annular lug 3213. The first annular lug 3213 is formed radially outward from the body 3212 and protrudes from the body 3212. The positioning holes correspond one-to-one with the first annular lugs 3213 and are formed in the first annular lugs 3213. The outer wall of the annular projection 14 is provided with at least one second annular lug 141. A positioning column is provided on the second annular lug 141 to ensure the integrity of the body 3212 and the annular projection 14 and prevent damage to the body 3212 and the annular projection 14.

[0079] The image acquisition unit 6 , for example, acquires the graphic positions of the positioning cylinder and the corresponding positioning hole, and calculates the center coordinate difference to determine whether the free end portion 321 is installed in place.

[0080] In an exemplary embodiment, Figure 1 、 Figure 2 、 Figure 4 As shown, the fingerprint module installation device further includes a second driving portion 8, which is connected to the first supporting component 1, and is configured to drive the first supporting component 1 to move in a horizontal direction.

[0081] The second driving unit 8 includes a second driving body 81 and a mounting bracket 82. The second driving body 81 can be, for example, a driving cylinder. The second driving body 81 is horizontally positioned, with the cylinder of the second driving body 81 fixedly connected to the mounting bracket 82. The piston end of the second driving body 81 is fixedly connected to the outer wall of the first supporting body 11 of the first supporting assembly 1. In the driven state, the piston end of the second driving body 81 drives the first supporting body 11 to move horizontally.

[0082] In this embodiment, if Figure 1 、 Figure 4 As shown, the fingerprint module installation device further includes a support base 9, and the first bearing assembly 1, the second bearing assembly 2 and the second driving unit 8 are respectively installed on the support base 9. Among them, the second driving unit 8 is fixedly connected to the support base 9 through a mounting bracket 82.

[0083] In this embodiment, if Figure 1 、 Figure 2 、 Figure 4 As shown, the fingerprint module installation device also includes a first guide portion 91 installed on the support base 9, and the first bearing assembly 1 includes a second guide portion 16. In the driving state, the first bearing assembly 1 moves along the first guide portion 91 through the second guide portion 16.

[0084] In one example, the first guide portion 91 includes two slide rails, which are respectively provided on both sides of the first bearing assembly 1 and extend along the first direction (refer to Figure 1The second guide portion 16 extends in the X-axis direction (as shown), and each slide rail is fixedly connected to the support base 9. The second guide portion 16 includes two sliders, one on each side of the first carrier assembly 1, and each slider is fixedly connected to the lower surface of the first carrier body 11 of the first carrier assembly 1. The sliders correspond to the slide rails one by one and are slidably connected, allowing the sliders to drive the first carrier body 11 to move along the slide rails.

[0085] Among them, each slide rail is provided with two blocking blocks 911, and the two blocking blocks 911 are respectively arranged on both sides of the slide rail, and each blocking block 911 is fixedly connected to the support base 9 and one end of the slide rail. When the slider slides to the end on the slide rail, the blocking block 911 can prevent the slider from moving and prevent the slider from sliding out of the slide rail. At the same time, the blocking block 911 can also limit the slider. When the slider slides to one of the blocking blocks 911, it means that the first supporting component 1 moves to the target position, and the shell 33 and the half-mold component 31 are correspondingly arranged in the vertical direction. When the slider slides to the other blocking block 911, it means that the first supporting component 1 and the second supporting component 2 are completely staggered, and the worker can remove the half-mold component 31 or place the half-mold component 31.

[0086] In this embodiment, if Figure 1 、 Figure 4 As shown, the second supporting assembly 2 includes a second supporting body 21 fixedly connected to the support base 9, and a second groove 22 formed in the second supporting body 21. The mold half assembly 31 is placed in the second supporting body 21. Two second grooves 22 are provided, one on each side of the second supporting body 21. The second grooves 22 are recessed into the upper surface of the second supporting body 21, and the distance between the second grooves 22 is slightly smaller than the width of the mold half assembly 31, making it easier for workers to pick up the mold half assembly 31. The lower surface of the second supporting body 21 is fixedly connected to the support base 9, improving the stability of the second supporting body 21.

[0087] In this embodiment, if Figure 1 、 Figure 4 As shown, the second support assembly 2 also includes a plurality of stoppers 23, such as stoppers, which are simple and easy to implement. These stoppers 23 are arranged circumferentially around the mold half assembly 31 and are slidably connected to the second support body 21. The second support body 21 is provided with a plurality of mounting slots 211, which are arranged circumferentially around the mold half assembly 31. The stoppers 23 are correspondingly mounted within these slots 211.

[0088] When the mold half 31 is placed on the second carrier body 21, the stopper 23 is pushed so that it abuts against the outer peripheral wall of the mold half 31, thereby limiting the movement of the mold half 31. The stopper 23 is higher than the surface of the second carrier body 21 to ensure that the stopper 23 abuts against the outer peripheral wall of the mold half 31.

[0089] In this embodiment, if Figure 1 、 Figure 4 As shown, the fingerprint module installation device also includes a third sensing portion 24 arranged on the second supporting body 21. The third sensing portion 24 is configured to sense the placement status of the half-mold assembly 31 to facilitate confirmation of whether the half-mold assembly 31 is placed on the second supporting assembly 2.

[0090] The third sensing unit 24 may be, for example, but not limited to, a Hall effect sensor, and is in communication with the second driving unit 8. When the third sensing unit 24 senses the presence of the mold half 31 on the second supporting assembly 2, it generates and transmits an indication signal to the second driving unit 8, causing the piston end of the second driving unit 8 to drive the first supporting assembly 1 in a horizontal direction until the mold half 31 aligns with the housing 33.

[0091] In this embodiment, if Figure 1 、 Figure 4 As shown, the fingerprint module installation device further includes a display unit 92 and a control unit 93 , and the display unit 92 and the control unit 93 are respectively arranged on the support base 9 .

[0092] The display unit 92 is, for example, a display screen, mounted on the support base 9 . The display unit 92 can display, for example, the process steps, assembly parameters, and assembly time of the fingerprint module installation device.

[0093] The control unit 93 can be, for example, an emergency stop switch 931 and a start switch 932. The start switch 932 is used to start the installation device of the fingerprint module, and the emergency stop switch 931 is used to emergency shut down the installation device of the fingerprint module so that when an emergency occurs, the installation device of the fingerprint module can stop working in time.

[0094] In this embodiment, if Figure 1-Figure 5 As shown, the support base 9 also houses a control chip and electronic control circuitry, which provide power and control for the entire fingerprint module assembly. For example, the control chip communicates with the first drive unit 5, the second drive unit 8, the first sensing unit 43, the second sensing unit 7, the third sensing unit 24, the first magnetic element 42, the second magnetic element 13, the image acquisition unit 6, the display unit 92, and the control unit 93 via the electronic control circuitry.

[0095] During the specific implementation process, the half mold assembly 31 equipped with the fingerprint module 32 is placed in the second supporting assembly 2 , and the limiting portion 23 is pushed to limit the movement of the half mold assembly 31 .

[0096] The third sensing unit 24 senses the mold half 31. The control chip receives the sensing result and sends a control instruction to control the second driving unit 8 to drive the first supporting assembly 1 in a horizontal direction. The first supporting assembly 1 moves along the first guide portion 91 until the first supporting assembly 1 is aligned with the second supporting assembly 2. The first magnetic body 42 and the second magnetic body 13 are energized to generate an attractive force.

[0097] The free end 321 of the fingerprint module 32 is placed on the annular protrusion 14 of the first supporting component 1. The control chip sends a control instruction to control the first driving unit 5 to drive the adsorption unit 4 to move in the vertical direction. The first magnetic body 42 of the adsorption unit 4 absorbs the free end 321 of the fingerprint module 32 and places the free end 321 on the positioning column in the predetermined area, and then releases the free end 321.

[0098] The image acquisition unit 6 captures the graphical positions of the positioning post and the positioning hole of the free end portion 321 within the predetermined area. The control chip receives these graphical positions and calculates the difference in center coordinates between the two to determine whether the free end portion 321 is properly installed. If not, the first drive unit 5 is driven to drive the suction unit 4 toward the free end portion 321, sucking the free end portion 321 and repositioning the free end portion 321 based on the calculated results. After placement, the image acquisition unit 6 continues to capture image information within the predetermined area to further confirm whether the free end portion 321 is properly installed. If not, the suction and placement operations are repeated until the positioning hole and the positioning post are plugged in and connected, and the second magnetic element 13 sucks the free end portion 321.

[0099] The housing 33 is placed on the first carrier assembly 1. When the first sensing unit 43 senses the presence of the housing 33 on the first carrier assembly 1 and the second sensing unit 7 senses the absence of foreign objects within the preset range, the control chip receives the sensing result and sends a control instruction to the first driving unit 5. The first driving unit 5 drives the adsorption unit 4 in a vertical direction. The pressing body 41 of the adsorption unit 4 applies pressure to the housing 33, causing the adhesive on the free end 321 to form a cold pressure activation, and the free end 321 is attached to the housing 33. The first driving unit 5 resets, and the housing 33 and half-mold assembly 31 are removed and placed in a foam box, and then flow to the next workstation. The control chip controls the second driving unit 8 to reset, waiting for the assembly of the next fingerprint module 32.

[0113] Among them, the installation device of the fingerprint module is provided with an image acquisition unit 6, which can collect image information in a predetermined area to further confirm whether the free end 321 is installed in place.
