[0002] A foldable electronic device (such as a folding mobile phone) is connected by a rotating shaft device to two relatively rotatable parts, so as to realize the opening and closing of the two parts, thereby enabling the electronic device to have a folding function. During the production process, the two parts to be connected need to be respectively assembled and connected to the rotating shaft device of the electronic device, and after the assembly, the opening angle of the electronic device needs to be detected to determine whether the assembly result is qualified. At present, the control level of the assembly result is relatively poor.

[0053] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0054] In the description of the present application, the description with reference to terms such as "one embodiment", "some embodiments", "example" or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0055] In the description of this specification, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0056] See Figure 1 , the first body 110 and the second body 120 of the electronic device need to be assembled and connected through the rotating shaft device 130, so that the first body 110 and the second body 120 can rotate relative to each other around the rotation axis S of the rotating shaft device 130 to complete the opening and folding actions of the electronic device. The usage states of the electronic device at least include a flattened state, in which the opening angle between the first body 110 and the second body 120 is 180° or close to 180°. It is easy to understand that according to the quality control requirements, when the user uses the flattened state of the electronic device, the deviation between the opening angle between the first body 110 and the second body 120 and 180° cannot be too large, that is to say, if the opening angle between the first body 110 and the second body 120 exceeds a certain range, the angle requirement for the flattened state cannot be met. For example, it can be stipulated that the opening angle of the flattened state of the electronic device shall not exceed the range of 179.5° to 181° (including the end values). Then, during the factory inspection, when the electronic device is opened to the flattened state, if the opening angle between the first body 110 and the second body 120 is less than 179.5° or greater than 181°, it means that the product is unqualified.

[0057] In the related art, the detection passing rate of the first assembly connection between the first body 110 and the second body 120 is relatively poor, that is, the existing assembly process has a relatively poor control level over the assembly result, resulting in a considerable part of the assembly work needing to be reworked during mass production, which will undoubtedly affect the production efficiency of the electronic device and increase the cost burden of the enterprise. In view of this, the present application provides an assembly device to improve the detection passing rate of the first assembly connection between the first body 110 and the second body 120, avoid or reduce the rework assembly work during mass production, and thus improve the production efficiency of the enterprise.

[0058] See Figures 2 to 11, embodiments of the present application provide an assembly device for completing the assembly connection of the first body 110 and the second body 120 of an electronic device. The electronic device can have various types, such as a folding mobile phone, a folding tablet computer, a laptop computer, etc. The first body 110 and the second body 120 are two parts of the electronic device connected by a rotating shaft device 130. The assembly device includes a first carrier assembly 210, a second carrier assembly 220, a detection assembly 270, and a driving assembly 230. Among them, the first carrier assembly 210 is used to carry the rotating shaft device 130 and the first body 110 that have been assembled and connected together. The second carrier assembly 220 is rotatably connected to the first carrier assembly 210 and is used to carry the second body 120 to be assembled and connected to the rotating shaft device 130. The second body 120 is located on the side of the rotating shaft device 130 away from the first body 110. The detection assembly 270 is used to detect the assembly angle of the first body 110 and the second body 120 in a plane that satisfies the perpendicular condition with the rotation axis S of the rotating shaft device 130. The driving assembly 230 is connected to the first carrier assembly 210 and / or the second carrier assembly 220 and is used to drive the first carrier assembly 210 and the second carrier assembly 220 to rotate relative to each other. When the assembly angle does not meet the target angle, the driving assembly 230 drives at least one of the first carrier assembly 210 and the second carrier assembly 220 to rotate to adjust the assembly angle to the target angle. When the assembly angle meets the target angle, the first body 110 and the second body 120 meet the flattening condition.

[0059] That the rotating shaft device 130 and the first body 110 have been assembled and connected together means that the connecting parts (such as screws, bolts, etc.) between the rotating shaft device 130 and the first body 110 have been installed. It is easy to understand that by simply assembling and connecting the rotating shaft device 130 and the second body 120, the first body 110 and the second body 120 can be rotatably connected through the rotating shaft device 130. That is to say, the assembly connection between the rotating shaft device 130 and the first body 110 has been completed before using the assembly device of the present application, or in other words, the rotating shaft device 130 and the first body 110 have been connected together in the material preparation stage.

[0060] The first bearing component 210 and the second bearing component 220 are components of the assembly device for bearing materials, where the materials are the objects to be assembled. During feeding, the first body 110 and the second body 120 are respectively placed on the first bearing component 210 and the second bearing component 220, and the second body 120 is located on the side of the rotating shaft device 130 away from the first body 110. It should be noted that there are various situations for the feeding sequence of the first body 110 and the second body 120. For example, the first body 110 that has been assembled and connected to the rotating shaft device 130 can be first placed on the first bearing component 210, and then the second body 120 is placed on the second bearing component 220. Or, the second body 120 can be first placed on the second bearing component 220, and then the first body 110 that has been assembled and connected to the rotating shaft device 130 is placed on the first bearing component 210. Or, the second body 120 and the rotating shaft device 130 connected to the first body 110 can be pre-assembled first (that is, only roughly positioned, and the connecting parts between the second body 120 and the rotating shaft device 130 are not installed), and then the first body 110 and the second body 120 are simultaneously placed on the corresponding bearing components.

[0061] After feeding, only pre-assembly is completed between the second body 120 and the rotating shaft device 130, and the connecting parts (such as screws, bolts, etc.) are not installed yet. Before installing the connecting parts for connecting the second body 120 and the rotating shaft device 130, the assembly angles of the first body 110 and the second body 120 are adjusted through the detection component 270 and the driving component 230. This assembly angle refers to the angle presented by the first body 110 and the second body 120 in the plane that satisfies the perpendicular condition with the rotation axis S of the rotating shaft device 130. It is easy to understand that the first bearing component 210 and the second bearing component 220 can rotate relative to each other under the action of the driving component 230. Since the first body 110 and the second body 120 are respectively located on the first bearing component 210 and the second bearing component 220, the first body 110 and the second body 120 can rotate relative to each other when the driving component 230 acts, so that the above-mentioned assembly angle of the first body 110 and the second body 120 can be changed. It should be noted that since the first body 110 and the rotating shaft device 130 are connected together before feeding, the first body 110 and the rotating shaft device 130 are relatively fixed during the process of adjusting the assembly angle of the first body 110 and the second body 120.

[0062] The connection of the driving component 230 with the first bearing component 210 and / or the second bearing component 220 includes three cases. The first case: The driving component 230 is connected to the first bearing component 210, and only the first bearing component 210 is driven to rotate when adjusting the assembly angle. The second case: The driving component 230 is connected to the second bearing component 220, and only the second bearing component 220 is driven to rotate when adjusting the assembly angle. The third case: The driving component 230 is connected to both the first bearing component 210 and the second bearing component 220. When adjusting the assembly angle, either the first bearing component 210 or the second bearing component 220 can be driven to rotate, or both can be driven simultaneously to make both rotate.

[0063] The detection component 270 can detect the assembly angle between the first body 110 and the second body 120 in real time. The driving component 230 adjusts the assembly angle towards the target angle based on the detection value of the detection component 270. When the assembly angle meets the target angle, the driving component 230 stops operating. At this time, the first body 110 and the second body 120 meet the flattening condition. It should be noted that the first body 110 and the second body 120 meeting the flattening condition means that the first body 110 and the second body 120 are in a horizontally opened state, and the opening angle between them can be 180° at this time, or a value near 180°. The assembly angle meeting the target angle means that the assembly angle is adjusted to a certain preset value or a value near the preset value. It is easy to understand that the preset value can be 180°, or a value very close to 180° and differing little from 180°. For example, the target angle can be set to 179.5° - 180°, so that the bending degree of the opening angle of the first body 110 and the second body 120 in the flattened state of the electronic device after assembly relative to the theoretical value (i.e., 180°) is controlled within 0.5°.

[0064] When the assembly angle meets the target angle, install and connect the connecting piece between the second body 120 and the rotating shaft device 130, and then take away the assembled first body 110, second body 120 and rotating shaft device 130 together from the assembly device. As can be seen from the above working process, when using the assembly device of the present application, the detection component 270 detects the assembly angle between the first body 110 and the second body 120 in real time, and the driving component 230 adjusts the assembly angle based on the detection value of the detection component 270, so that it can be more accurately adjusted to the required target angle, so that the assembled first body 110 and second body 120 can pass the qualified detection at one time, avoiding the generation of rework assembly work, which helps the enterprise improve production efficiency. It should be understood that before installing and connecting the connecting piece between the second body 120 and the rotating shaft device 130, that is, before locking the second body 120 and the rotating shaft device 130, by adjusting the assembly angle between the first body 110 and the second body 120 to a preset target angle, it can be ensured that after locking the second body 120 and the rotating shaft device 130, the flatness (i.e., the flattening degree) of the whole of the first body 110 and the second body 120 meets the requirements. It should be noted that in mass production, the consistency of the flatness of the whole of the first body 110 and the second body 120 after assembly is related to the state of the materials, and different target angles may need to be set to adapt to different batches of materials. When setting the target angle for a certain batch of materials, the target angle suitable for this batch of materials can be obtained through a limited number of tests (such as the first 3 to 5 products of this batch).

[0065] In some embodiments, the detection component 270 may include: a first laser, located on the side of the first bearing component 210 facing away from the first body 110, the first laser 271 is fixedly connected to the frame of the assembly device, and is used to determine the first plane where the first body 110 is located by emitting dot lasers to at least three points on the first body 110; a second laser 272, located on the side of the second bearing component 220 facing away from the second body 120, the second laser 272 is fixedly connected to the frame, and is used to determine the second plane where the second body 120 is located by emitting dot lasers to at least three points on the second body 120; an arithmetic unit (not shown in the figure), electrically connected to the first laser 271 and the second laser 272, and is used to calculate the included angle between the first plane and the second plane to obtain the assembly angle.

[0066] As mentioned before, the assembly angle between the first body 110 and the second body 120 refers to the angle presented by the two in the plane perpendicular to the rotation axis S of the rotating shaft device 130. See Figure 1, the above-mentioned assembly angle can be understood as the included angle or its supplementary angle between the first plane where the first body 110 is located and the second plane where the second body 120 is located. It should be understood that the intersection line of the first plane where the first body 110 is located and the second plane where the second body 120 is located is parallel to the rotation axis S of the rotation shaft device 130. In order to detect the assembly angle between the first body 110 and the second body 120, the first plane where the first body 110 is located and the second plane where the second body 120 is located can be located first, and then the included angle between the first plane and the second plane can be calculated, so as to obtain the above-mentioned assembly angle.

[0067] See Figure 2 , Figure 5 and Figure 6 , the first laser 271 and the second laser 272 are fixed on the laser mount 273, and the laser mount 273 is relatively fixed to the frame of the assembly device. Therefore, the positions of the first laser 271 and the second laser 272 remain unchanged in the system coordinate system with the frame as the reference. Using the principle of laser ranging, the coordinates of at least three non-collinear position points on the first body 110 in the system coordinate system can be determined through the first laser 271, and then the first plane where the first body 110 is located can be determined using the coordinates of these position points. Similarly, the second plane where the second body 120 is located can be determined using the second laser 272. After both the first plane and the second plane are determined, the included angle between the first plane and the second plane can be obtained through geometric calculation. That is to say, the position coordinates of the first laser 271 and the second laser 272 themselves are preset known data, and the distances measured by the first laser 271 and the second laser 272 from each point are measurement data. The arithmetic unit can automatically calculate the included angle between the first plane and the second plane using these known data and detection data, and its calculation method can adopt conventional geometric calculation. The assembly angle refers to the angle formed by the first body 110 and the second body 120 before the second body 120 and the rotation shaft device 130 are locked. In order to ensure that the flatness of the overall first body 110 and the second body 120 meets the requirements after the second body 120 and the rotation shaft device 130 are locked, the assembly angle needs to be adjusted to an appropriate value range (this appropriate value range is the "target angle" mentioned in this article). By setting the first laser 271, the second laser 272 and the arithmetic unit, the assembly angle can be measured in real time, and then calibrated and adjusted according to the predetermined target angle, so that the assembly angle finally meets the target angle. At this time, the first body 110 and the second body 120 meet the flattening condition and meet the requirements of normal folding.

[0068] Of course, in other embodiments, the detection component 270 can also be configured in other forms. For example, the detection component 270 can be configured to include an angle sensor, which is disposed on the first bearing component 210 and / or the second bearing component 220 driven by the driven component 230, and is used to detect the angle passed by the rotational movement. The initial angle between the first bearing component 210 and the second bearing component 220 is preset known data. After the first body 110 and the second body 120 are respectively positioned on the first bearing component 210 and the second bearing component 220, the assembly angle between the first body 110 and the second body 120 is the same as the angle between the first bearing component 210 and the second bearing component 220. Therefore, by measuring the angle passed by the rotational movement in real time through the angle sensor and combining the initial angle, the assembly angle between the first body 110 and the second body 120 can be determined.

[0069] In some embodiments, the driving component 230 may include: a driving motor, located on one side of the rotational connection of the first bearing component 210 and the second bearing component 220 along a direction parallel to the rotational axis S of the first bearing component 210 and the second bearing component 220. The output shaft of the driving motor 231 is connected to the first bearing component 210 or the second bearing component 220. When the rotating shaft device 130 and the first body 110 are carried on the first bearing component 210, the rotational axis S of the rotating shaft device 130 and the axis of the output shaft satisfy the parallel condition. With such a setting, by driving one of the first bearing component 210 and the second bearing component 220 to rotate by the driving motor 231 to adjust the assembly angle, not only can the number of motor configurations be reduced, but also the overall layout of the components can be made more compact, saving occupied space. Refer to Figure 3 , Figure 4 and Figure 7 , the driving motor 231 is fixedly installed on the motor mounting seat 232, and the motor mounting seat 232 is relatively fixed to the frame of the assembling device. The motor mounting seat 232 is provided with a hinge seat 233 for hingedly mounting the second bearing component 220. The output shaft of the driving motor 231 and the hinge hole on the hinge seat 233 can be coaxially arranged. In this way, the output shaft of the driving motor 231 can be directly connected to the first bearing component 210 or the second bearing component 220 to achieve direct drive. In Figure 3 and Figure 7 the embodiment exemplarily shown, the second bearing component 220 includes a connecting shaft 2211 directly connected to the output shaft of the driving motor 231.

[0070] Of course, in other embodiments, the driving component 230 can also be configured in other forms. For example, the driving component 230 can be configured to include a telescopic cylinder, and the movable end of the telescopic cylinder is connected to one end of the first bearing component 210 away from the second bearing component 220, or to one end of the second bearing component 220 away from the first bearing component 210. By applying a force to one end of the first bearing component 210 or the second bearing component 220 away from the other, the stressed bearing component is rotated.

[0071] In some embodiments, the first bearing component may include a first carrier plate 211 and a first pressing plate 212 capable of moving relative to the first carrier plate 211. One side of the first carrier plate 211 facing the first pressing plate 212 is used to carry the rotating shaft device 130 and the first body 110, and the first pressing plate 212 is used to press the first body 110 against the first carrier plate 211. After loading, before adjusting the assembly angle, pressing the first body 110 against the first carrier plate 211 by using the first pressing plate 212 can make the first body 110 more firmly located on the first bearing component 210 without dislocation or shaking. It should be noted that during the process of adjusting the assembly angle between the first body 110 and the second body 120, the first pressing plate 212 and the first carrier plate 211 remain relatively fixed. Similarly, in some embodiments, the second bearing component 220 may include a second carrier plate 221 and a second pressing plate 222 capable of moving relative to the second carrier plate 221. One side of the second carrier plate 221 facing the second pressing plate 222 is used to carry the second body 120, and the second pressing plate 222 is used to press the second body 120 against the second carrier plate 221. Of course, in other embodiments, the body of the electronic device can also be firmly temporarily fixed on the bearing component by other means. For example, a groove for positioning and clamping the side of the body of the electronic device can be provided on the bearing component. After placing the body of the electronic device in the groove on the bearing component, the inner wall of the groove and the side of the body of the electronic device are in interference fit, so that the body of the electronic device is clamped in the groove and will not be dislocated or shaken relative to the bearing component.

[0072] See Figure 3 、 Figure 7 and Figure 8, in some embodiments, the second pressing plate may be provided with a guiding hole 2221. The position of the guiding hole 2221 corresponds to the connecting hole of the second body 120 and the rotating shaft device 130. The guiding hole 2221 is used to guide the connecting member 140 connecting the second body 120 and the rotating shaft device 130 to the connecting hole. After the assembly angle of the first body 110 and the second body 120 is adjusted to the target angle, it is necessary to install the connecting member 140 into the connecting hole to connect the second body 120 and the rotating shaft device 130. By providing the guiding hole 2221 corresponding to the position of the connecting hole on the second pressing plate 222, the position of the connecting member 140 can be easily found and placed, and the guiding hole 2221 plays a certain role in straightening the connecting member 140, so that the connecting member 140 is not easily skewed or shaken during the installation process.

[0073] In some embodiments, a first through hole for exposing a part of the first body 110 may be provided on the side of the first carrier plate facing away from the first pressing plate 212. The first through hole is used for the laser emitted by the detection component 270 to pass through so that the laser hits the surface of the first body 110. As mentioned before, the first plane where the first body 110 is located and the second plane where the second body 120 is located can be determined by setting a laser, and then the assembly angle between the first body 110 and the second body 120 can be determined. To determine the first plane where the first body 110 is located by using a laser, the laser can be emitted to three points on the surface of the first body 110, and the first plane can be determined by the three-point positioning method. In order to enable the laser to hit the surface of the first body 110, the first carrier plate 211 should be avoided from blocking the laser. Therefore, a first through hole can be provided on the first carrier plate 211 to avoid the laser. In some embodiments, the first through hole may be set as a hollowed-out area in the middle of the first carrier plate 211, and the side of the first carrier plate 211 facing away from the first body 110 is integrally in a frame shape. Of course, the first through hole can also be set to at least three, corresponding to different points on the surface of the first body 110 respectively. Similarly, in some embodiments, a second through hole for exposing a part of the second body 120 may be provided on the side of the second carrier plate 221 facing away from the second pressing plate 222. The second through hole is used for the laser emitted by the detection component 270 to pass through so that the laser hits the surface of the second body 120.

[0074] See Figure 3, in some embodiments, the first carrier plate 211 and the first pressing plate 212 may be configured to be connected by a first telescopic cylinder 213. The fixed end of the first telescopic cylinder 213 is mounted on the first carrier plate 211, and the movable end of the first telescopic cylinder 213 is connected to the first pressing plate 212. The first pressing plate 212 is driven to move relative to the first carrier plate 211 by the first telescopic cylinder 213. The first telescopic cylinder 213 may have various types, for example, it may be a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, etc. Similarly, the second carrier plate 221 and the second pressing plate 222 may be configured to be connected by a second telescopic cylinder 223, and the second telescopic cylinder 223 may have various types, for example, it may be a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, etc.

[0075] In some embodiments, the first bearing assembly may include a first guide post 214 for guiding the relative movement of the first carrier plate 211 and the first pressing plate 212. The first guide post 214 is fixedly connected to the first pressing plate 212. It is easy to understand that the first carrier plate 211 is slidably engaged with the first guide post 214, and the first guide post 214 can keep the relative movement of the first pressing plate 212 and the first carrier plate 211 in a straight line, minimizing the shaking during the movement. Similarly, the second bearing assembly 220 may include a second guide post 224 for guiding the relative movement of the second carrier plate 221 and the second pressing plate 222. The second guide post 224 is fixedly connected to the second pressing plate 222, so that the second pressing plate 222 and the second carrier plate 221 can move relative to each other better along a straight line.

[0076] In some embodiments, the assembly device may include a manipulator (not shown in the figure). An installation tool is provided at the end of the manipulator for installing a connecting member 140 that connects the second body 120 and the rotating shaft device 130. After the assembly angle is adjusted to the target angle, it is necessary to install the connecting member 140 to connect the rotating shaft device 130 and the second body 120 together. By providing a manipulator (i.e., a robotic arm), this step can be automated, thus saving manpower. For example, an electric screwdriver is provided at the end of the manipulator for installing a screw that connects the second body 120 and the rotating shaft device 130.

[0077] In some embodiments, the assembly device may include an indicator light for indicating the current state of the assembly device. Refer to Figure 2 , the indicator light may include a first indicator light 261 and a second indicator light 262. One of the two is in a lit state when the assembly angle meets the target angle, and the other is in a lit state during the actuation of the drive assembly 230. For example, the first indicator light 261 may be configured to indicate that the assembly angle is being adjusted, and the second indicator light 262 may be configured to indicate that the assembly angle meets the requirements and the second body 120 and the rotating shaft device 130 can be locked.

[0078] In some embodiments, the assembly device may include a reset trigger 250 disposed on the outer surface of the assembly device. When the reset trigger 250 is operated, it can trigger the automatic reset program of the assembly device, so that the first carrier assembly 210 and / or the second carrier assembly 220 are restored to a preset initial position under the drive of the drive assembly 230. The reset trigger 250 can have various types, such as a button, a lever, etc. The staff operates the reset trigger 250 to make the assembly device execute the automatic reset program, thereby preparing for the next assembly work. Refer to Figure 2 , Figure 10 and Figure 11 , in the embodiment where the carrier assembly includes a pressing plate and a carrier plate that can move relative to each other, after the automatic reset program is started, the pressing plate performs the reverse action of the pressing movement to achieve reset. It should be noted that after loading, the pressing plate performs a pressing movement to press the material tightly on the carrier plate. During the process of adjusting the assembly angle of the first body 110 and the second body 120, the pressing plate and the corresponding carrier plate are relatively fixed differently, that is, the pressing plate and the corresponding carrier plate rotate synchronously with the pressed material, so as to ensure that the pressing force received by the material remains unchanged during the assembly angle process.

[0079] In some embodiments, the assembly device may include an input device 240 for setting the value of the target angle. Since different batches of materials may vary in material properties, manufacturing errors, etc., different batches of materials may require different target angles. Refer to Figure 2 , the input device 240 can be set as a control panel. The staff can adjust and set the value of the target angle through the input device 240, so that the assembly device can easily adapt to different batches of materials and set an appropriate target angle (that is, the value range to which the assembly angle of the first body 110 and the second body 120 needs to be adjusted before the second body 120 and the rotating shaft device 130 are locked).

[0080] The present application also provides an assembly method, including the following steps: Step S1, placing the shaft device 130 and the first body 110 that have been assembled and connected together into the first carrier assembly 210, and placing the second body 120 to be assembled and connected to the shaft device 130 into the second carrier assembly 220. The second body 120 is located on the side of the shaft device 130 away from the first body 110; Step S2, the detection component 270 detects the assembly angle of the first body 110 and the second body 120 in a plane perpendicular to the rotation axis S of the shaft device 130, compares the assembly angle with a preset target angle. In the case where the assembly angle does not meet the target angle, the driving component 230 drives the first carrier assembly 210 and the second carrier assembly 220 to rotate relative to each other, so that the assembly angle is adjusted to the target angle to achieve that the first body 110 and the second body 120 meet the flattening condition; Step S3, installing the connecting piece 140 that connects the second body 120 and the shaft device 130.

[0081] In the above assembly method, Step S1 completes the feeding of materials, Step S2 completes the adjustment of the assembly angle, and Step S3 completes the installation of the connecting piece 140. In Step S1, there can be various situations for the feeding sequence of the first body 110 and the second body 120. For example, the first body 110 that has been assembled and connected to the shaft device 130 can be first placed on the first carrier assembly 210, and then the second body 120 is placed on the second carrier assembly 220. Or, the second body 120 can be first placed on the second carrier assembly 220, and then the first body 110 that has been assembled and connected to the shaft device 130 is placed on the first carrier assembly 210. Or, the second body 120 and the shaft device 130 connected to the first body 110 can be pre-assembled (that is, only roughly positioned, and the connecting piece 140 connecting the second body 120 and the shaft device 130 is not installed), and then the first body 110 and the second body 120 are placed on the corresponding carrier assemblies simultaneously.

[0082] In Step S2, there can be various situations for the way the driving component 230 drives the first carrier assembly 210 and the second carrier assembly 220 to rotate relative to each other. For example, the driving component 230 can drive only one of the first carrier assembly 210 and the second carrier assembly 220 to rotate, or the driving component 230 can drive both the first carrier assembly 210 and the second carrier assembly 220 to rotate simultaneously. In Step S3, the connecting piece 140 can be installed manually or automatically by a manipulator.

[0083] Taking the case where the target angle is set to deviate from 179° by no more than 0.2° as an example, after the feeding is completed, the detection component 270 detects the assembly angle of the first body 110 and the second body 120. If the detected assembly angle is not within the range of 169.8° to 179.2°, the driving component 230 drives the first bearing component 210 and the second bearing component 220 to rotate relative to each other, so that the assembly angle is increased (when the detected value of the assembly angle is less than 169.8°) or decreased (when the detected value of the assembly angle is greater than 179.2°) by a certain value (for example, 0.3°), and then the above steps are repeated until the detected value of the assembly angle is within the range of 169.8° to 179.2°. The assembly angle adjustment is completed. At this time, the indicator light of the assembly device lights up, indicating that the locking can be performed, that is, the locking of the second body 120 and the rotating shaft device 130 can be performed. In some embodiments, the assembly method may include: after the locking is completed, the staff operates the reset trigger 250 to return the assembly device to the initial state, and then the staff removes the assembled material (that is, the first body 110, the second body 120 and the rotating shaft device 130 connected together) from the assembly device.
