Description

TECHNICAL FIELD

[0002] As a mainstream wearable smart device, the basic structure of a smart watch usually includes a watch case and a button, wherein the button is integrated on the side of the watch case and is a core component for realizing human-computer interaction. Users can trigger the corresponding function response of the device through different operation modes such as twisting and pressing.

[0003] Specifically, the button of the smart watch is often designed with differentiated structures to distinguish functions: one is a first button with a whole circular shape, and the other is a second button with a whole square shape. The functions of the two buttons are clear: when the first button is twisted, the fine adjustment of device parameters can be realized, such as adjusting the volume level, the screen display brightness, the alarm setting time, or adjusting the target speed, the target distance, and other numerical parameters in the motion mode; when the second button is pressed, the directional selection and module switching operation can be completed, such as switching options in the menu list, the contact interface, or the input interface, such as selecting a specific contact, adjusting the alarm time parameter, and switching between different function modules such as the time display module, the motion monitoring module, and the heart rate monitoring module. Through the differentiated operation of the two types of buttons, users can efficiently complete the interaction with the smart watch and realize diversified function calling. However, in the current related technology, the assembly of the watch case and the button of the smart watch is still mainly operated by humans.

[0023] To achieve the above-mentioned purpose, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 , the watch case assembly line body is used for assembling a watch case and a key assembly, the watch case includes a first mounting hole and a second mounting hole, the watch case is provided with a key support at the outer periphery of the second mounting hole, the key assembly includes a first key and a second key, the first key includes a first key body and a snap spring, the second key includes a second key body 2 and a screw, and the watch case assembly line body includes: a base 10, the base 10 is provided with a first assembly unit 11, a second assembly unit and a conveying module 14; the first assembly unit 11 is configured to assemble the first key body and the snap spring to the first mounting hole of the watch case; the second assembly unit is configured to sequentially assemble the second key body 2 to the second mounting hole of the watch case and assemble the screw to the key support to be assembled with the second key body 2; the conveying module 14 is configured to convey the watch case between the first assembly unit 11 and the second assembly unit.

[0024] The watch case assembly line body provided by the application is used for assembling a watch case and a key assembly. The watch case comprises a first mounting hole and a second mounting hole. The watch case is provided with a key support at the outer periphery of the second mounting hole. The key assembly comprises a first key and a second key. The first key comprises a first key body and a snap spring. The second key comprises a second key body and a screw. The first key and the second key body are two different types of keys. For example, the first key is a circular key, which is usually twisted. The first key is a square key, which is usually pressed. A user controls the smart wearable device to realize different functions by exerting different actions on different keys.

[0025] It can be understood that the watch case assembly line body has a basic feeding unit 15 and a discharging unit 16. The feeding unit 15 provides a watch case that has not been assembled with a key support or a watch case pre-assembled with a key support. The discharging unit 16 is used for storing or transferring the watch case assembled with the key. Between the feeding unit 15 and the discharging unit 16, a first assembly unit 11 and a second assembly unit are arranged. The watch case assembly line body can have an assembly process of the feeding unit 15 to the first assembly unit 11 to the second assembly unit, or an assembly process of the feeding unit 15 to the second assembly unit to the first assembly unit 11. The assembly process is not limited in the application.

[0026] It needs to be explained that when the feeding unit 15 provides a watch case that has not been assembled with a key support, the watch case assembly line body can first complete the assembly of the first key, and then assemble the key support by manual mode. The watch case is conveyed into the second assembly unit by the conveying module 14 to assemble the second key. When the feeding unit 15 provides a watch case pre-assembled with a key support, the assembly of the second key can be completed first. The watch case is conveyed into the first assembly unit 11 by the conveying module 14 to assemble the first key.

[0027] Specifically, the base 10 refers to a rigid frame structure for carrying various functional modules. Specifically, a welded steel structure or a numerically controlled machined aluminum profile frame can be used to realize the base 10, which provides a stable mounting reference for the assembly unit. The first assembly unit 11 refers to a special workstation for performing the assembly of the first key. Specifically, a multi-axis mechanical arm can be used in cooperation with a visual positioning system to realize the first assembly unit 11, which ensures the coaxiality of the first key body and the mounting hole. The second assembly unit refers to a special workstation for performing the assembly of the second key. Specifically, a servo press-fitting mechanism can be used in cooperation with a spring pre-tightening device to realize the second assembly unit, which accurately controls the spring compression stroke. The conveying module 14 refers to a material conveying system. Specifically, one or a combination of multiple conveying devices such as a conveying belt 141, a shuttle car, and a guide rail 142 can be used in the conveying module 14, which is not limited herein.

[0028] The conveying module 14 is distributed in the base 10, which has two core functions: the first core function is to realize the flow of the watch case between different units, such as between the first assembly unit 11 and the second assembly unit, and between the feeding unit 15 and the first assembly unit 11; the second core function is to realize the flow of the watch case between different stations of any unit, for example, in the first assembly unit 11, the first assembly unit 11 at least has a watch case taking station, a key top lifting station, and a flat spring pushing station. First, the watch case is conveyed from the previous unit to the watch case taking station of the first assembly unit 11 under the action of the conveying module 14. In the watch case taking station, the watch case can be taken down and fixed using a mechanical arm, a first case overturning mechanism 111, and other equipment. Then, under the sliding of the mover of the guide rail 142, it enters the key top lifting station, and the insertion of the first key body is completed in the key top lifting station. In summary, the conveying module 14 distributed in multiple positions of the base 10 plays the role of connecting the assembly actions of the watch case assembly line, so that each assembly action is no longer independent and the assembly of the watch case and the key is completed in an orderly manner.

[0029] In the first assembly unit 11, the first key body can be introduced into the first mounting hole of the watch case through a mechanical arm, a directional pushing mechanism, or other devices. Then, the flat spring is pressed into the watch case, so that the flat spring, the first key body, and the watch case form an integral whole. The second assembly unit performs two processes. First, the key body is embedded. The second key body 2 is grabbed by a mechanical arm or adsorbed by a vacuum chuck, an electrostatic adsorption device, or other devices. Then, the second key body 2 is inserted into the second mounting hole from top to bottom in the vertical direction. An electric screwdriver (with a torque sensor) moves to the bracket screw hole position, and the screw is screwed into the key body bottom thread hole and the bracket hole, thereby realizing the fixed assembly of the key bracket, the second key body, and the watch case.

[0030] In the technical solution, the watch case assembly line realizes the full automation of the assembly of the watch case and the key assembly through the first assembly unit 11, the second assembly unit, and the conveying module 14 integrated by the base 10. Among them, the assembly of the first key body and the flat spring with the first mounting hole of the watch case, and the assembly of the second key body 2 and the screw with the second mounting hole of the watch case and the key bracket, are respectively completed by the first and second assembly units, which avoids the problems of assembly position deviation and uneven force that easily occur during manual operation, effectively reduces product defects caused by human errors, improves product yield, solves the bottleneck of yield fluctuation in manual assembly in the background technology, and at the same time, the conveying module 14 can automatically convey the watch case between the first assembly unit 11 and the second assembly unit, without the need for manual transportation and station switching. The operation efficiency of each assembly unit is much higher than that of manual assembly, which can realize continuous and large-scale assembly operation, greatly improve the overall product processing efficiency, meet the demand for large-scale production of smartwatches, and make up for the defects of low efficiency and difficulty in adapting to mass production in manual assembly in the background technology.

[0031] In an embodiment of the present application, the first assembly unit 11 comprises a first case overturning mechanism 111, a jacking mechanism 112, and a spring push mechanism 113. The first case overturning mechanism 111 is configured to overturn and rotate the watch case so that the first mounting hole of the watch case is aligned with the lifting end of the jacking mechanism 112; the jacking mechanism 112 is configured to drive the first key body at the lifting end to move upward so as to assemble the first key body to the first mounting hole of the watch case; The spring push mechanism 113 is configured to push the spring into the watch case so as to assemble the spring with the first key.

[0032] In this embodiment, the first assembly unit 11 integrates the first case overturning mechanism 111, the jacking mechanism 112, and the spring push mechanism 113 to form a standardized automatic assembly process for the key assembly. First, the first case overturning mechanism 111 overturns and rotates the watch case to achieve accurate alignment of the first mounting hole with the lifting end of the jacking mechanism 112. Compared with manual adjustment of the posture of the watch case, this mechanism can control the hole alignment deviation within a high-precision range by mechanical limiting and driving control, such as a servo motor driving a rotating shaft, to ensure that the first key body / second key can be inserted along the axis direction of the mounting hole, avoiding hole wall scratches or key jamming caused by skewing, and ensuring accuracy from the beginning of assembly. Second, the jacking mechanism 112 carries and jacks the first key body through the lifting end, replacing the manual pressing action. The driving force provided by the air cylinder or servo cylinder can be accurately set, and different driving forces can be provided for different key types, for example, the jacking force for a small mass first key body is set to 5-8 N, and the jacking force for a large mass first key body is set to 10-15 N, which can ensure that the key is completely inserted into the mounting hole, avoid assembly misplacement caused by insufficient manual pressing force, prevent key or watch case deformation caused by excessive torque, and solve the problem of uneven manual operation force. After the first key is assembled, the watch case can move towards the spring push mechanism 113 under the action of the conveying module 14, so that the spring push mechanism 113 assembles the spring with the key through a flat pushing action. The spring push mechanism 113 can also move towards the first case overturning mechanism 111, which is not limited again. Compared with manual installation of the spring using tweezers and other tools, this mechanism can constrain the posture of the spring through limiting structure and push the spring into the watch case with constant pushing force or linearly changing pushing force, ensuring accurate circumferential or axial positioning of the spring and the key, and avoiding the risk of key falling caused by loose spring.

[0033] In an embodiment, the first shell overturning mechanism 111 is composed of a multi-stage rotary joint and a clamping mechanism at the free end of the multi-stage rotary joint, the multi-stage rotary joint realizing switching of different postures of the watch case, and the clamping mechanism being used for taking out and clamping the outer surface of the watch case from the tray; the jacking mechanism 112 is composed of a jacking drive, a guide assembly and a positioning jig, the jacking drive 1121 providing lifting power, the guide assembly ensuring the straightness of the lifting movement, for example, by the cooperation of a linear slide rail and a slide block, and the positioning jig being designed to have a profiling groove according to the outer shape of the first key body to realize accurate positioning and positioning of the key.

[0034] In another embodiment, the jacking mechanism 112 includes a jacking drive 1121, a workpiece carrier 1122, a guide 1124 and a key carrier 1123, the workpiece carrier 1122 being fixed on the surface of the base 10, the guide 1124 being located on the side of the workpiece carrier 1122 away from the surface of the base 10 in a posture perpendicular to the surface of the base 10, the extension direction of the guide 1124 being perpendicular to the surface of the base 10, the workpiece carrier 1122 being movably arranged through the guide 1124, the jacking drive 1121 being arranged between the workpiece carrier 1122 and the key carrier 1123, the lifting end of the jacking drive 1121 being connected to the key carrier 1123, the first key body being arranged on the carrying surface of the key carrier 1123, under the action of the jacking drive 1121, the first key body being capable of being inserted into the corresponding first mounting hole of the watch case, thereby realizing the assembly between the watch case and the first key body; in this embodiment, the first shell overturning mechanism 111 with the watch case is capable of reaching above the workpiece carrier 1122 under the action of the conveying module 14, it can be known that the watch case can be rotated before the first shell overturning mechanism 111 reaches above the workpiece carrier 1122, so that the mounting hole of the watch case is aligned with the corresponding key, or the watch case can be overturned after the first shell overturning mechanism 111 reaches above the workpiece carrier 1122, so that the mounting hole of the watch case is aligned with the corresponding key, which is not limited here.

[0035] In another embodiment, the pushing mechanism includes a flat pushing drive 1131 and a clasp limiting piece 1132, the clasp limiting piece 1132 being connected to the movable end of the flat pushing drive 1131; the flat pushing drive 1131 is configured to drive the clasp limiting piece 1132 to translate towards the watch case, so that the clasp is assembled with the first key body.

[0036] The flat push driving part 1131 refers to an execution element capable of generating linear motion power, and can be specifically implemented by an electric push rod or a pneumatic sliding table. The flat push driving part 1131 provides accurate translational driving force for the snap spring limiting part 1132. The snap spring limiting part 1132 refers to a mechanical component with a guide groove or a positioning structure, and can be specifically implemented by a limiting block with a V-shaped groove. The snap spring limiting part 1132 physically constrains the snap spring and guides the snap spring to move along a set path, so as to ensure that the snap spring and the button are accurately aligned in the assembly position.

[0037] In the first assembly unit 11, the base 10 is provided with a snap spring warehouse and a snap spring taking robot near the pushing mechanism. Before the snap spring pushing mechanism 113 and the first shell overturning mechanism 111 are aligned, the snap spring taking robot takes the snap spring from the snap spring warehouse and assembles the snap spring to the snap spring limiting part 1132. Through the automatic process, the problem of missing watch cases can be avoided.

[0038] Specifically, in the snap spring assembly process, the snap spring limiting part 1132 fixes the initial position of the snap spring through the guide groove. After the flat push driving part 1131 is started, the snap spring limiting part 1132 is stably moved in the horizontal direction. When the snap spring limiting part 1132 moves to the edge of the mounting hole of the watch case, the snap spring is pushed into the first button under the guidance of the limiting part, and the mechanical locking of the snap spring and the first button is completed. In this process, the translation path of the snap spring limiting part 1132 remains unchanged with the axis of the watch case mounting hole, so as to avoid the deflection or inclination of the snap spring during the assembly process.

[0039] In an embodiment of the present application, the base 10 is provided with a watch case taking station, a button lifting station and a snap spring flat pushing station in the first assembly unit 11. The first shell overturning mechanism 111 is arranged corresponding to the watch case taking station, the lifting mechanism 112 is arranged corresponding to the button lifting station, and the snap spring flat pushing station is arranged corresponding to the snap spring pushing mechanism 113. The conveying module 14 is further configured to convey the watch case to flow between the watch case taking station, the button lifting station and the snap spring flat pushing station.

[0040] In the embodiment, by setting the watch case taking station, the key lifting station, and the clasp spring pushing station in the first assembly unit 11, and making the first case overturning mechanism 111, the lifting mechanism 112, and the clasp spring pushing mechanism 113 correspond to each station one by one, and relying on the conveying module 14 to realize the circulation of the watch case between the stations, an automatic assembly system with clear division of labor and collaborative linkage is constructed. First, the watch case taking station serves as the starting point of assembly, and only bears the tasks of grabbing the watch case and adjusting the initial posture. The first case overturning mechanism 111 does not need to consider the subsequent key assembly action, and can focus on the stable clamping and posture calibration of the watch case after taking the material from the tray, avoiding the action interference caused by function combination, and ensuring that the watch case does not fall off or be damaged during the grabbing process. The key lifting station focuses on the alignment and assembly of the key and the watch case mounting hole, and the lifting mechanism 112 does not need to consider the previous taking and placing of the watch case, and only needs to accurately control the lifting track of the key, to ensure that the key can be smoothly inserted along the axis of the mounting hole, and avoid alignment deviation caused by too many action considerations. The clasp spring pushing station is responsible for the cooperation and fixation of the clasp spring and the key, and the clasp spring pushing mechanism 113 can focus on the posture maintenance and pushing path control of the clasp spring, to prevent the clasp spring from deviating or deforming during assembly. This specialized division of labor makes the function of each mechanism more focused, greatly reduces the operation error of a single mechanism due to bearing multiple tasks, and improves the assembly accuracy from the source. The automatic circulation of the watch case between the stations driven by the conveying module 14 completely replaces the link of manually transferring the watch case, bringing double advantages. On the one hand, mechanical circulation can ensure the position accuracy of the watch case during transfer between stations, avoid the deviation of the watch case reference caused by hand shaking and placement deviation during manual handling, ensure that the mounting hole can be accurately aligned with the corresponding mechanism when the watch case enters the next station, and reduce the process time without additional posture adjustment. On the other hand, automatic circulation can realize the beat coordination of each station, and the transfer speed of the watch case can be dynamically matched according to the assembly time of each station, to avoid the accumulation of watch cases or the stagnation of no watch cases for assembly at a certain station, make the production process of the entire assembly unit more coherent, and greatly improve the overall assembly efficiency.

[0041] In an embodiment of the present application, the second assembly unit comprises a key body feeding subunit 12 and a screw feeding subunit 13, the key body feeding subunit 12 is connected with the screw feeding subunit 13, and the conveying module 14 is further configured to convey the watch case from the key body feeding subunit 12 to the screw feeding subunit 13; the key body feeding subunit 12 comprises a second case overturning mechanism 121 and a key body lowering mechanism 122, the screw feeding subunit 13 comprises a third case overturning mechanism 131, a watch case fixing tool 132, and a screw feeding mechanism 133; the second case overturning mechanism 121 is configured to overturn and rotate the watch case so that the second mounting hole of the watch case is opposite to the lifting end of the key body lowering mechanism 122, the key body lowering mechanism 122 is configured to drive the second key body 2 located at the lifting end to be assembled to the second mounting hole of the watch case, the third case overturning mechanism 131 is configured to receive the watch case and convey it to the watch case fixing tool 132, the watch case fixing tool 132 is configured to switch the watch case to a screw feeding posture, and the screw feeding mechanism 133 is configured to assemble a screw to the key support to be assembled with the second key body 2.

[0042] In the present embodiment, the second case overturning mechanism 121 is a core component for realizing accurate adjustment of the posture of the watch case, and can be composed of a multi-stage rotary joint and a clamping mechanism. Its core function is to adjust the posture of the watch case after receiving the watch case conveyed by the conveying module 14 through mechanical action, so that the second mounting hole of the watch case is opposite to the lifting end of the key body lowering mechanism 122. The multi-stage rotary joint is driven by a servo motor, which can realize overturning (such as turning from a horizontal posture to a vertical posture) and fine adjustment of the watch case (rotation angle accuracy ≤0.1°), so as to ensure that the coaxiality error between the second mounting hole and the positioning structure of the key body lowering mechanism 122 is within an acceptable error range; the clamping mechanism fixes the watch case through a constant clamping force of 6-10 N, which not only prevents the watch case from falling off, but also avoids pressing the surface coating or structure of the watch case, so that the posture of the watch case is stable at all times until the key body embedding process is completed. The key body lowering mechanism 122 is responsible for smoothly embedding the second key body 2 into the second mounting hole of the watch case, and can be composed of a lowering driving member such as a servo air cylinder, a linear motor, a guide assembly such as a linear slide rail combined with a sliding block, and a key body positioning jig. The key body positioning jig fixes the second key body 2 through a profiling groove and vacuum adsorption to prevent the key body from deviating or falling off; the guide assembly ensures the straightness of the jig during lifting to avoid skewing of the key body during embedding; the servo air cylinder can accurately control the lowering speed and thrust, which can not only ensure that the key body is completely embedded in the hole, but also prevent the key body or the watch case from being deformed due to excessive torque. After embedding is completed, the jig releases the vacuum and resets, waiting for the next operation. The third shell overturning mechanism 131 undertakes the dual tasks of watch case transfer and preliminary attitude adjustment, and is structurally continued with the multi-stage rotary joint and clamping mechanism design, but the function is more focused on "linking" and "adaptability". Its core function is to receive the watch case embedded with the second key body 2 from the conveying module 14, quickly grab it, and drive the watch case to complete the second overturning, so that the screw hole of the key support is consistent with the direction of the electric screwdriver bit of the screw feeding mechanism 133, providing a precise torque transmission path for subsequent screw locking, while ensuring that the watch case attitude does not deviate during transfer, avoiding screw hole misalignment. The watch case fixing tool 132 is a key guarantee for the stability of the watch case during screw locking, and is designed for "anti-torque" requirements, with multi-point clamping and precise positioning functions. When the third shell overturning mechanism 131 places the watch case into the tool, the tool applies clamping force through multiple movable clamps and barb structures to offset the counter-torque during screw locking and prevent the watch case from rotating with the screwdriver.

[0043] The screw feeding mechanism 133 is responsible for screw selection, feeding, and precise locking, and can be composed of screws, a feeding tube, and an electric screwdriver. The screws are screened out by vibration to remove defective screws, and the qualified screws are sorted in the "head forward" attitude and blown into the bit through the feeding tube; the electric screwdriver fixes the screw through magnetic attraction, moves to the front of the screw hole, and then advances axially. When the tightening action is started, the torque sensor monitors the torque in real time, and stops automatically when the set value is reached and reverses for a preset number of turns. If the torque is abnormal, an alarm is triggered to ensure the quality of screw locking. When the watch case enters the second assembly unit, it is first grabbed by the second shell overturning mechanism 121 of the key body feeding subunit 12 from the conveying module 14, the attitude is adjusted so that the second mounting hole is directly opposite the lifting end of the key body lowering mechanism 122, and then the positioning jig of the key body lowering mechanism 122 is driven by a servo cylinder to smoothly descend along the guide assembly, and the second key body 2 is embedded in the second mounting hole at a set speed and pushing force. After the key body is embedded, the watch case is transferred to the screw feeding subunit 13 by the conveying module 14, the third shell overturning mechanism 131 quickly grabs the watch case and overturns it to the posture suitable for screw feeding, and places it into the watch case fixing tool 132, which fixes the watch case through multi-point clamping and positioning pins. Then the screw feeding mechanism 133 selects and feeds the screws to the electric screwdriver bit, the bit adsorbs the screw, and then aligns the screw hole, starts the tightening action, and the torque sensor monitors and ensures the locking quality. After the screw assembly is completed, the watch case fixing tool 132 releases the clamps, the third shell overturning mechanism 131 sends the watch case back to the conveying module 14, and transfers it to the next link. The entire process is realized through the precise cooperation of each mechanism to achieve automatic and high-precision assembly of the second key.

[0044] In an embodiment of the present application, the first and second shell overturning mechanisms 111 and 121 each include a first overturning portion 1111 and a rotating portion 1112, the rotating portion 1112 is fixedly arranged on the first overturning portion 1111, and the rotating portion 1112 is configured to fix the watch case; the first overturning portion 1111 is used to overturn the watch case, so as to switch the watch case from the flat posture to the first vertical posture, and the rotating portion 1112 is used to rotate the watch case, so as to make the insertion port of the first mounting hole face the jacking mechanism 112 or the insertion port of the second mounting hole face the key body lowering mechanism 122 in the first vertical posture.

[0045] In the embodiment, the first and second shell overturning mechanisms 111 and 121 each include a first fixed portion 1114, a first rotating shaft 1113, a first overturning portion 1111, a rotating portion 1112, and a driving member, the first fixed portion 1114 not only provides a fixed basis for other components of the two shell overturning mechanisms, but also fixedly connects the conveying module 14, so as to realize the circulation of the watch case between different workstations; specifically, the first fixed portion 1114 can be spliced by multiple sheet metal parts, or be a separate component, and is connected with different structures by means of grooves, holes, protrusions and the like; the first fixed portion 1114 is provided with a shaft hole, the first rotating shaft 1113 is inserted into the shaft hole of the fixed portion, the first overturning portion 1111 is connected with the first rotating shaft 1113, and when the driving member operates, the first rotating shaft 1113 drives the first overturning portion 1111 to overturn, so as to switch the watch case from the flat posture to the first vertical posture, i.e., from the state shown in FIG. 6A to the state shown in FIG. 6B. Figure 3 Figure 4 At this time, the axes of the first and second mounting holes of the watch case change from the parallel relationship to the intersecting relationship with the surface of the base 10, and then the rotating portion 1112 drives the shell to rotate by a preset angle or feeds back the rotation angle through the positioning camera, so as to make the insertion ports of the first and second mounting holes face the first or second key body, so that the first or second key body can be inserted into the corresponding mounting hole, and the assembly of the key body and the watch dial is realized.

[0046] ​In an embodiment, the rotating part 1112 has two clamping arms that can approach and move away from each other, and the two clamping arms are inserted into the hollow area of the watch case at the same time and then cooperate with the inner peripheral wall of the watch case, so as to realize the fixation between the rotating part 1112 and the watch case, or the rotating part 1112 is designed to adapt to the specific shape and size of the watch case, so that the rotating part 1112 can extend into the hollow area of the watch case and then cooperate with the inner peripheral wall of the watch case, so as to realize the fixation between the rotating part 1112 and the watch case, or the rotating part 1112 has clamping arms acting on the outer peripheral surface of the watch case, so as to avoid structural interference when the first key body and the second key body 2 are inserted; the rotating part 1112 can rotate under the driving of the rotating motor, so as to realize the jacking mechanism 112 of the first assembly unit 11 or the key body lowering mechanism 122 of the second assembly unit in the alignment of the mounting hole of the watch case in the vertical posture.

[0047] It can be understood that the flat posture refers to the posture in which the axis of the first mounting hole or the second mounting hole of the watch case is parallel to the surface of the base 10, and the flat posture can be that the front surface of the watch case faces the surface of the base 10, or can be that the back surface of the watch case faces the surface of the base 10; the first vertical posture and the second vertical posture refer to the posture in which the axis of the first mounting hole or the second mounting hole of the watch case intersects with the surface of the base 10, and when the key is needed to be assembled, the rotation of the rotating part 1112 makes the axis of the first mounting hole or the second mounting hole perpendicular to the surface of the base 10 or forms a specific angle with the surface of the base 10, so as to facilitate the insertion of the key body.

[0048] In an embodiment of the present application, the third shell overturning mechanism 131 includes a second overturning part 1311 and a locking part 1312, and the locking part 1312 is arranged on the overturning part; the second overturning part 1311 is used for overturning the watch case, so as to switch the watch case from the flat posture to the second vertical posture, and the locking part 1312 has at least two locking members that can approach and move away from each other, and each locking member is configured to abut against the inner peripheral surface of the watch case and be positioned away from the second key body 2 and the key bracket.

[0049] In this embodiment, the third shell flipping mechanism 131 includes a second fixing portion 1314, a second rotating shaft 1313, a second flipping portion 1311, a locking portion 1312 and a driving member. The second fixing portion 1314 not only provides a fixing basis for other components of the third shell flipping mechanism 131, but also can be fixedly connected to the conveying module 14, thereby realizing the flow of the watch case between different workstations. Specifically, the second fixing portion 1314 can be spliced ​​by multiple sheet metal parts, or be a separate component, and realize connection with different structures by providing grooves, holes, protrusions and other structures; the second fixing portion 1314 is provided with an axial hole, and the second rotating shaft 1313 is inserted into the axial hole of the second fixing portion 1314, and the locking portion 1312 is connected to the second rotating shaft 1313. When the driving member is running, the second rotating shaft 1313 drives the second flipping portion 1311 to flip, so that the watch case switches from a flat posture to a second upright posture.

[0050] Please see Figure 10 The locking portion 1312 includes four locking pieces, which are arranged at intervals along the circumferential direction. In this way, when clamping the watch case, a multi-point clamping area and a uniform clamping force can be formed. Specifically, two aligned locking pieces are inserted into the hollow area of ​​the watch case to abut against the inner circumferential surface of the watch case, and the other two aligned locking pieces are shorter in length to abut against the inner end surface of the watch case. In this way, multiple spaced locking pieces can completely avoid the first key body, the second key body 2 and the key bracket to prevent the pre-assembled parts from changing their posture. It can be understood that in the subsequent screw driving process, it is necessary to ensure the height of the position between the screw hole on the watch case and the bit of the screw feeding mechanism 133. Therefore, after the watch case is transported to the watch case fixing tool 132, a high-precision posture fine-tuning is required. Therefore, for the third shell flipping mechanism 131, it is only necessary to ensure that the watch case can be placed on the watch case fixing tool 132, and there is no need to set up a rotating portion 1112 for posture adjustment.

[0051] In one embodiment of the present invention, the case fixing tool 132 includes a case carrier and a case locking portion, and the case locking portion is arranged on the case carrier; the case locking portion has at least two locking members that can approach and move away from each other, and each locking member is configured to abut the inner circumference of the case and offset the second key body 2 and the key bracket; the case locking portion is configured to switch the case from the second upright posture to the screw loading posture.

[0052] In the embodiment, the watch case carrier can adopt a planar support structure or a curved surface profiling structure, for example, a positioning pin or a vacuum suction hole is arranged on the support surface, which is used to constrain the displacement of the watch case in the horizontal direction, and the locking member can be selected from a wedge block, a pneumatic clamping jaw or an electromagnetically driven sliding block, the moving path of which forms an included angle with the normal direction of the inner circumferential surface of the watch case, for example, the locking member is cut into the inner wall of the watch case at a preset angle, and the multi-point dynamic clamping is realized through the friction and structural limiting.

[0053] When the watch case is placed on the watch case carrier, the watch case carrier can fix the bottom surface of the watch case through vacuum suction, and then the two locking members are driven away from each other by the driving member such as a cylinder or a motor, so as to form a clamping action on the watch case. At the same time, during the movement of the locking member, at least a period of time will be in contact with the watch case, so that after the locking member is moved to the position, the posture of the watch case on the watch case carrier can be changed, so as to force the watch case into the screw feeding posture.

[0054] In an embodiment of the present application, please refer to Figure 8 , the screw feeding subunit 13 is provided with a watch case material taking station and a watch case locking station, the third shell overturning mechanism 131 is arranged corresponding to the watch case material taking station, and the screw feeding mechanism 133 is arranged corresponding to the watch case locking station; the screw feeding subunit 13 has a watch case butt joint state, in which the locking part 1312 is opposite to the locking surface of the watch case carrier.

[0055] In the embodiment, the third shell overturning mechanism 131 is arranged corresponding to the watch case material taking station, so that the watch case material taking station receives the watch case located on the third shell overturning mechanism 131, and the screw feeding mechanism 133 is arranged corresponding to the watch case locking station, so as to perform the screw feeding process; in this process, the watch case fixing tool 132 moves between the watch case material taking station and the watch case locking station, so as to realize the transfer of the watch case; wherein, when the watch case fixing tool 132 receives the watch case of the third shell overturning mechanism 131, the locking part 1312 of the third shell overturning mechanism 131 is opposite to the locking surface of the watch case carrier, so that when the watch case is transferred, the watch case in the second vertical posture can be prevented from changing the posture.

[0056] In an embodiment of the present application, the second shell overturning mechanism 121 further comprises a key body abutting part, which is fixedly arranged on the first overturning part 1111 and / or the rotating part 1112; the key body abutting part is configured to abut and limit the second key body 2 of the watch case.

[0057] In the embodiment, the key body abutting portion is protruded on the surface of the first turning portion 1111 and / or the rotating portion 1112, and when the rotating portion 1112 is clamped to the watch case, the key body abutting portion can abut against the second key body 2 limited on the watch case, because when the watch case needs to flow from the key body on the feeding subunit 12 to the screw feeding subunit 13, in order to facilitate the stable flow of the watch case, the watch case needs to flow in a flat posture, and the second key body on the watch case has not been locked by the screw, and the watch case is in a first vertical posture, therefore, the watch case needs to be switched from the first vertical posture to the flat posture, that is, the first turning portion 1111 rotates, and the second key body is easy to deviate or fall off in the turning process due to gravity or centrifugal force, therefore, by setting the key body abutting portion, the posture of the second key body 2 on the watch case can be always restricted, and the position deviation of the second key body 2 relative to the key support in the turning process of the watch case is avoided; it can be understood that the key body abutting portion can be a protruding point structure, which realizes the limitation of the second key body 2 through a multi-point contact mode, or can be a plurality of L-shaped limiting blocks, so that part of the structure of the second key body 2 is clamped into the key body abutting portion, and the shape of the key body abutting portion is not limited.
