[0042] In order to make the purpose, technical solutions and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limiting this application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0044] In the following description, the terms "first\second" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It is understandable that "first\second" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0046] Before further describing the embodiments of the present application in detail, the technical solutions for related technologies involved in the embodiments of the present application are described:

[0047] 1. The screen opening mechanism of electronic devices mostly uses a cam-type hinge, which is usually manually locked using a motorized screwdriver. Since manual locking is a single-station operation, it is inefficient. Furthermore, within the same batch of hinges, varying locking angles and forces can lead to poor torque consistency across the hinges, requiring additional man-hours for further torque adjustments.

[0048] Currently, shaft torque adjustment in the shaft industry is mostly done manually, using a manual wrench to adjust the shaft torque to within a given specification. Different operating techniques significantly impact the shaft adjustment results, and during the adjustment process, test instruments can only digitally display the instantaneous torque value, making it impossible to monitor process data during the adjustment process.

[0049] 3. Retesting the shaft's torque is also done manually. The shaft is secured to the torque tester via a carrier base, rotated using a shift fork, and manually determined to see if the shaft torque is within specified specifications. Due to the influence of manual control, frequency, and direction, shaft torque measurements by different testers can vary significantly, and automatic shaft torque data cannot be collected.

[0050] 4. Free-down testing of the rotating shaft is typically performed using a hanging hammer jig. This test simulates the weight of the electronic device's display by calculating the weight of the hanging hammer. The test determines whether the hanging hammer falls when the rotating shaft is at the upper and lower angles of the display, confirming whether the rotating shaft is within specifications. Because the direction and position of the hanging hammer are manually controlled, different operating techniques can significantly affect the test results. Furthermore, this method has a very short judgment time, which can lead to misjudgment of slowly falling products.

[0051] In response to the problems existing in the above-mentioned methods provided by related technologies, an embodiment of the present application provides a method, device and electronic device for assembling the shaft of an electronic device, which can replace manual work to lock the shaft nut, and after the locking operation is completed, automatically perform torque detection on the finished shaft and update the locking torque, thereby improving the efficiency and accuracy of the assembly of the shaft nut.

[0052] The following describes an assembly method for a rotating shaft of an electronic device provided by an embodiment of the present application. Figure 1 , Figure 1 This is an optional processing flow diagram of the assembly method of the rotating shaft of the electronic device provided in the embodiment of the present application. Figure 1 Steps S101-S103 are shown for explanation.

[0053] Step S101: determining a preset locking torque.

[0054] In some embodiments, the nut locking torque and the corresponding specification torque for a third number of shafts from the same batch can be recorded in advance. The average of the quotients between the nut locking torque and the corresponding specification torque for the third number of shafts is determined as the preset torque parameter; and the product of the preset torque parameter and the specification torque of the shafts is determined as the preset locking torque. For shafts from the same batch, the specification torque of the shafts is determined after shipment.

[0055] Among them, there is a corresponding relationship between the locking torque of the electric starter and the shaft torque after the nut is assembled, which can be derived by the following formula:

[0056] The screen opening structure of electronic devices mostly adopts a rotating shaft with a concave cam structure. Figure 2A commonly used laptop hinge structure is provided, comprising a fixed support ①, a shaft ②, a rotating support ③, a gasket ④, a cam ⑤, a concave wheel ⑥, a silencer ⑦, a spring ⑧, and a nut ⑨. Shaft torque is typically generated by rotational friction between four pairs of friction surfaces in the shaft assembly: the shaft ②, the rotating support ③, the gasket ④, the cam ⑤, and the concave wheel ⑥. Pressure is generated by the spring ⑧. Due to the varying materials of the hinge assembly, the kinetic friction coefficients between the four pairs of friction surfaces vary. The kinetic friction coefficient between the axis ② and the rotating support ③ can be expressed by μ1, the kinetic friction coefficient between the rotating support ③ and the gasket ④ can be expressed by μ2, the kinetic friction coefficient between the gasket ④ and the cam ⑤ can be expressed by μ3, and the kinetic friction coefficient between the cam ⑤ and the cam wheel ⑥ can be expressed by μ4; if the four pairs of friction surfaces are simplified into two friction ring disks, let R be the outer diameter of the friction ring disk, r0 be the inner diameter of the friction ring disk, F be the pressure that the friction ring disk can withstand, μ be the kinetic friction coefficient between the friction surfaces, and there is a unit micro-ring with a radius of r and a width of d. r , then the shaft torque T2 is as shown in formula (1).

[0057]

[0058] The locking torque required for the nut to be locked must overcome the rotational friction between the washer ④ and the nut ⑨. The contact surface between the two can be simplified to a circular nut. Assume R L is the outer diameter of the nut, r L is the inner diameter of the nut, μ L is the dynamic friction coefficient between the gasket and the nut, F is the pressure on the friction surface, and a unit micro-circle is provided, with the radius of the micro-circle being r and the width of the unit micro-circle being d. r , then the locking torque T of the electric actuator required for the nut to be locked is L It can be shown as formula (2).

[0059]

[0060] From formula (1), we can get formula (3):

[0061] Formula (4) can be obtained from formula (2):

[0062] Based on the fact that F in the above formula (3) and formula (4) is the same, formula (5) can be obtained:

[0063]

[0064] Set torque parameter Then we can get formula (6):

[0065] T L =·T2(6)

[0066] From this, we can see that for the same rotating shaft, due to the dynamic friction coefficients μ1, μ2, μ3 and μ4 of the four pairs of friction surfaces, the outer diameter R of the friction ring disk, the inner diameter r0 of the friction ring disk, the dynamic friction coefficient μ between the gasket ④ and the nut ⑨ L is fixed, so for the same shaft, the Y value is fixed, and the locking torque T of the electric starter is L It is directly proportional to the shaft torque 2 after locking is completed.

[0067] The derivation of the above formula shows that when determining the preset locking torque, if we know the shaft's specification torque (i.e., the actual torque required after assembly), as well as the torque parameter, we can determine the preset locking torque by multiplying the two. This method allows for a very convenient and relatively accurate determination of the initial preset torque. Furthermore, in subsequent processes, by continuously updating the torque parameter and locking torque based on the proportional relationship, we can efficiently and accurately achieve this, ensuring that the torque of the assembled shaft meets production specifications.

[0068] In step S102 , the nut is assembled to the first rotating shaft based on the locking torque to obtain a second rotating shaft.

[0069] In some embodiments, a nut can be attached to the first rotating shaft using an electric motor based on a preset locking torque to obtain a second rotating shaft. The first rotating shaft is a semi-finished rotating shaft comprising a concave cam structure and lacking a nut, while the second rotating shaft is a finished rotating shaft after the nut has been attached to the first rotating shaft. The method of this application is applicable to all rotating shafts with a concave cam structure.

[0070] Step S103 : in response to the second rotating shaft satisfying the first condition, updating the locking torque to achieve assembly of the rotating shaft.

[0071] In some embodiments, because different batches of shafts require different locking torques, and because even slightly different parts within the same batch can cause slight variations in locking torque, to ensure that shafts assembled based on the locking torque consistently meet production specifications, the locking torque is updated when the second shaft meets the first condition. Continuously and regularly updating the locking torque during the shaft assembly process can maximize the assurance that all shafts meet production specifications upon assembly.

[0072] Among them, the second shaft meets the first condition including: the locking torque is recalculated and updated every time the number of second shafts assembled based on the current locking torque reaches a first quantity threshold, such as every time 100 shafts are assembled; or, the number of second shafts that fail to meet the torque condition continuously reaches a second quantity threshold; or, the number of second shafts that are assembled reaches the first quantity threshold, and the number of second shafts that fail to meet the torque condition continuously reaches the second quantity threshold.

[0073] In some embodiments, after the nut is assembled to the first rotating shaft to obtain the second rotating shaft, a torque test may be performed on the second rotating shaft to determine whether the assembled rotating shaft meets the torque condition.

[0074] During the torque test of the entire opening and closing cycle of each assembled second rotating shaft from 0° to 180° and then from 180° to 0°, the rotating shaft torque corresponding to different opening and closing angles can be obtained to obtain a torque curve. Each second rotating shaft has a corresponding torque curve. Figure 3 As shown in the torque curve, the X-axis data represents the angle of the shaft opening and closing. In the actual detection process, the torque value of 0° to -5° can be measured. T2 represents the torque in the smooth zone, that is, the torque of the second shaft obtained after the nut is assembled. Figure 3 The center represents the maximum torque value between 60° and 120° during the opening process of the shaft; the torque curve above the X-axis represents the torque curve of the shaft during the opening process, and the torque curve below the X-axis represents the torque curve of the shaft during the closing process.

[0075] Whether the torque of the second rotating shaft meets a condition can be detected based on the smooth region torque in the torque curve, the specification torque of the second rotating shaft, and the screen torque of the electronic device. The process of detecting whether the second rotating shaft meets the torque condition can include: determining the relationship between the difference between the smooth region torque and the specification torque and a first threshold; if the difference between the smooth region torque and the specification torque is less than or equal to the first threshold, continuing to perform a counterweight test on the second rotating shaft; if the second rotating shaft passes the counterweight test, it is determined that the second rotating shaft meets the torque condition; if the difference between the smooth region torque and the specification torque is greater than the first threshold, it is determined that the second rotating shaft does not meet the torque condition.

[0076] The process of performing the weight balancing test on the second rotating shaft may include obtaining a first rotating shaft torque corresponding to a first angle and a second rotating shaft torque corresponding to a second angle in a torque curve. If the first rotating shaft torque is less than a screen torque of the electronic device and the second rotating shaft torque is greater than the screen torque of the electronic device, then the second rotating shaft is determined to have passed the weight balancing test.

[0077] As an example, electronic devices such as notebooks often have such customer requirements: when the electronic screen of the notebook is closed, if the angle is less than the first angle, the electronic screen will be in a closed state; if the angle of the electronic screen is greater than the second angle during the opening process, the electronic screen will be in an open state. Therefore, it is necessary to perform a weight balance test on the rotating shaft of the electronic device. During the weight balance test, the first angle and the second angle can be determined according to actual needs. For example, the first angle can be set to 5° and the second angle can be set to 15°. Combined Figure 3 The torque curve shown determines that the value corresponding to 5° in the torque curve below the X-axis is the first shaft torque, and the value corresponding to 15° in the torque curve below the X-axis is the second shaft torque. If the first shaft torque is less than the screen torque of the electronic device and the second shaft torque is greater than the screen torque of the electronic device, it is determined that the second shaft passes the counterweight test.

[0078] In some embodiments, the process of updating the locking torque may be:

[0079] First, obtain the torque curves of all the second shafts assembled based on the current locking torque, determine the average value of the torque in the smooth area of ​​the torque curves of all the second shafts as the second shaft torque, and obtain the second shaft specification torque, that is, the torque that the second shaft should reach after assembly according to the production line requirements.

[0080] Next, update the torque parameter and locking torque. The current locking torque and the actual second shaft torque are used to determine the updated torque parameter. The updated locking torque is determined by multiplying the second shaft specification torque and the updated torque parameter. This is because the above formula has proven that, for the same shaft, the ratio of the locking torque to the assembled shaft torque is a constant value, namely the torque parameter. Once the updated torque parameter is determined, and since the second shaft specification torque is a fixed standard value, the corresponding locking torque can be obtained by multiplying the two.

[0081] The method for updating torque parameters and locking torque in the present application is simple and efficient, and can be conveniently applied to large-scale shaft assembly on the production line. Moreover, after the shaft meets the first condition, the locking torque is automatically updated, which can realize regular adjustment of the locking torque and torque parameters, greatly reducing the occurrence of torque that does not meet production conditions during the assembly of the shaft.

[0082] The following will be combined Figure 4 The following describes the system flow for automated assembly of a rotating shaft of another electronic device provided by an embodiment of the present application. Figure 4 , Figure 4 An optional system structure diagram for the automated assembly of a rotating shaft of an electronic device provided in an embodiment of the present application.

[0083] The central control instrument 404 can uniformly control the automatic assembly system and store the parameters used in the assembly process, such as preset torque parameters, preset locking torque, specification torque of the shaft, the self-torque of the screen of the electronic device and the first quantity threshold, second quantity threshold, third quantity, first threshold, etc. At the same time, the central control instrument 404 can also store the data of the detected shaft torque and display the torque curve in real time.

[0084] At the beginning of assembly, a first rotating shaft, i.e., a semi-finished rotating shaft without a nut, is stored on a fixed rack at the feed port 406. The first rotating shaft passes through a workstation turntable 407 to the electric nut lifter and locker 403. Simultaneously, a nut vibrating plate 401 delivers the nuts to be assembled to the electric nut lifter and locker 403 via an electric conveyor belt 402.

[0085] The electric nut locking device 403 locks the nut on the first shaft based on the preset locking torque stored in the central control device 404, completes the assembly operation, and obtains the second shaft, which represents the finished shaft after the nut is assembled.

[0086] After the second shaft is assembled, the workstation turntable 407 delivers the second shaft to the torque tester 405. The torque tester 405 places the second shaft's arm into the shift fork and simultaneously initiates the automatic testing process. During the shaft torque test, the servo motor activates, providing rotational power to the torque tester 405. The torque sensor built into the torque tester 405 collects the shaft torque signals corresponding to the different opening and closing angles of the second shaft throughout its entire opening and closing cycle, which are then input into the central control unit 404 for storage. The central control unit 404 then displays the torque curve corresponding to the second shaft currently being tested in real time.

[0087] When the torque tester 405 detects the second rotating shaft, the central control instrument 404 will obtain the smooth area torque based on the current torque curve, and at the same time obtain the pre-stored specification torque of the rotating shaft and the screen torque of the electronic device, compare the difference between the smooth area torque and the specification torque of the rotating shaft, and determine whether the second rotating shaft meets the torque conditions.

[0088] If the torque tester 405 detects that the difference between the smooth zone torque and the specification torque is less than or equal to the first threshold, the second shaft will enter the torque re-tester 409 to perform a counterweight test on the second shaft. If the counterweight test passes, it is determined that the second shaft meets the torque conditions and meets the production specifications.

[0089] When the torque retester 409 performs a counterweight test on the second rotating shaft, the first rotating shaft torque corresponding to the first angle and the second rotating shaft torque corresponding to the second angle in the torque curve of the central control instrument 404 are obtained, and whether the second rotating shaft passes the counterweight test is determined based on the first rotating shaft torque, the second rotating shaft torque and the screen torque of the electronic device. If the first rotating shaft torque is less than the screen torque of the electronic device, and the second rotating shaft torque is greater than the screen torque of the electronic device, it is determined that the second rotating shaft passes the counterweight test, and the test torque retester 409 determines that the second rotating shaft meets the production specifications. The second rotating shaft that meets the production specifications will be sent to the discharge port 412 for output. If the first rotating shaft torque is greater than the screen torque of the electronic device or the second rotating shaft torque is less than the screen torque of the electronic device when the torque retester 409 performs a counterweight test on the second rotating shaft, it is determined that the second rotating shaft does not meet the torque condition, that is, the second rotating shaft does not meet the production specifications. The second rotating shaft that does not meet the production specifications will be removed through the defective product conveyor track 411.

[0090] If the difference between the smooth area torque and the specification torque is greater than the first threshold, it is determined that the second rotating shaft does not meet the torque condition and does not meet the production specifications, and the second rotating shaft needs to be adjusted and retested.

[0091] As an example, if the torque tester 405 detects that the difference between the smooth area torque and the specification torque is greater than the first threshold value, the second shaft will enter the torque adjustment and retesting instrument 410, and the torque adjustment and retesting instrument 410 adjusts and retests the second shaft. If the difference between the smooth area torque of the adjusted second shaft and the specification torque of the shaft is less than or equal to the first threshold value during the retest, the adjusted second shaft is subjected to a weight test. If the first shaft torque of the adjusted second shaft is less than the screen torque of the electronic device and the second shaft torque of the adjusted second shaft is greater than the screen torque of the electronic device, the weight test passes, and it is determined that the adjusted second shaft meets the production specifications, and the adjusted second shaft that meets the production specifications is discharged through the discharge port 412; if the adjustment When the adjusted shaft is retested, if it is detected that the difference between the smooth area torque of the adjusted second shaft and the specification torque of the shaft is greater than the first threshold value, the adjusted second shaft will be adjusted again through the torque adjustment and retesting instrument 410; if when the adjusted shaft is retested, if it is detected that the difference between the smooth area torque of the adjusted second shaft and the specification torque of the shaft is less than or equal to the first threshold value, the adjusted second shaft will be subjected to a counterweight test. If, during the counterweight test, the adjusted second shaft detects that the first shaft torque of the adjusted second shaft is greater than the screen torque of the electronic device or the second shaft torque of the adjusted second shaft is less than the screen torque of the electronic device, the adjusted second shaft fails the counterweight test and the adjusted second shaft is removed through the defective product conveying crawler 411.

[0092] If the number of second rotating shafts that do not meet the torque conditions continuously detected by the torque tester 405 reaches a second number threshold, the central control unit 404 will update the currently stored locking torque and torque parameters based on the detection data of the torque tester 405. In the subsequent assembly process, the electric nut locking instrument 403 will assemble the rotating shaft based on the updated locking torque.

[0093] After the electric nut lifting and locking instrument 403 assembles the nut on the first shaft based on the preset locking torque to obtain the second shaft, the second shaft immediately enters the torque tester 405 for testing, and the central control instrument 404 counts the second shafts assembled based on the current locking torque. When the number of assembled second shafts reaches the first number threshold, the central control instrument 404 updates the currently stored locking torque and torque parameters based on the detection data of the torque tester 405, that is, in the actual production process, the locking torque will be updated regularly, and the preset torque parameters and preset locking torque may have been updated before the second shaft that does not meet the production specifications occurs continuously, which can improve the assembly accuracy of the shaft of the electronic device and avoid the situation where the shaft torque does not meet the production specifications due to inappropriate locking torque during the assembly process.

[0094] The method for the central control instrument 404 to update the locking torque and torque parameters may be:

[0095] Based on the test data from the torque tester 405 for all second shafts assembled based on the current locking torque, the central control instrument 404 obtains the smooth region torque from the shaft torque curve corresponding to each shaft. The average of the sum of all smooth region torques is determined as the second shaft torque. The ratio of the current locking torque to the second shaft torque is determined as the updated torque parameter. The updated torque parameter is then multiplied by the second shaft's specified torque to determine the updated locking torque. The central control instrument 404 stores the updated torque parameter and locking torque. The electric nut lifter and locking instrument 403 then continues to assemble nuts on the semi-finished shafts based on the updated locking torque.

[0096] The assembly of the electronic device's rotating shaft is achieved through an automated assembly system, avoiding the unstable locking torque of the electric starter caused by traditional manual assembly methods, thereby improving the stability of the process; automatic testing, torque retesting and further adjustment of the assembled rotating shaft are achieved, thereby improving the efficiency and accuracy of the rotating shaft assembly; by storing the corresponding data during the entire process of rotating shaft assembly and testing, the problem of being unable to monitor process data during manual assembly is avoided.

[0097] Figure 5This is a schematic diagram of an optional device structure of an assembly device for the rotating shaft of an electronic device provided in an embodiment of the present application. The assembly device 500 for the rotating shaft of an electronic device includes a parameter determination module 501, a rotating shaft assembly module 502, and a parameter update module 503.

[0098] A parameter determination module 501 is used to determine a preset locking torque;

[0099] a shaft assembly module 502 for assembling the nut to the first shaft based on the locking torque to obtain a second shaft;

[0100] The parameter updating module 503 is configured to update the locking torque in response to the second rotating shaft satisfying the first condition, so as to achieve assembly of the rotating shaft.

[0101] In some embodiments, the parameter determination module 501 is used to: obtain the nut locking torque of a third number of rotating shafts; determine the average value of the quotient between the nut locking torque of the third number of rotating shafts and the corresponding specification torque as a torque parameter; and determine the product of the torque parameter and the specification torque as the preset locking torque.

[0102] In some embodiments, the parameter updating module 503 is used to: at least one of: the number of second rotating shafts assembled based on the locking torque reaches a first number threshold, and the number of second rotating shafts that fail to meet the torque condition continuously reaches a second number threshold.

[0103] In some embodiments, the parameter update module 503 is also used to: obtain the torque curve of each second rotating shaft; and detect whether the torque of the second rotating shaft meets the torque condition based on the smooth area torque in the torque curve, the specification torque of the second rotating shaft and the screen torque of the electronic device.

[0104] In some embodiments, the parameter updating module 503 is further used to: if the difference between the smooth area torque and the specification torque is less than or equal to a first threshold, perform a balancing test on the second rotating shaft; if the difference between the smooth area torque and the specification torque is greater than the first threshold, determine that the second rotating shaft does not meet the torque condition.

[0105] In some embodiments, the parameter update module 503 is also used to: obtain a first shaft torque corresponding to a first angle and a second shaft torque corresponding to a second angle in the torque curve; perform a weight balancing test on the second shaft based on the first shaft torque, the second shaft torque and the screen torque of the electronic device.
