[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. Additionally, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.
[0048] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0049] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.
[0050] In the description of this embodiment, the orientation or positional relationship such as "above", "below", "left", and "right" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.
[0051] Please refer to Figure 1, in this embodiment, a key assembly device is proposed, which includes a frame 100, an assembly seat 200, a fixing part 400, and an assembly part 500. The assembly seat 200 is arranged on the frame 100 and is used to carry a key assembly jig 300 (hereinafter referred to as the assembly jig for short) for achieving the alignment between the watch case and the key; the fixing part 400 is arranged on the frame 100, and the fixing part 400 is used to fix the key assembly jig 300 on the assembly seat 200; the assembly part 500 is arranged on the frame 100 and is aligned with the mounting hole 41 of the assembly jig, and the assembly part 500 is used to push the key in the mounting hole 41 to the corresponding mounting position.
[0052] In practical applications, the frame 100 is arranged in the vertical direction. Under the action of the assembly jig, the alignment between the watch case and the key can be quickly completed. Subsequently, the assembly jig is placed on the assembly seat 200. One side of the assembly jig can be attached to the frame 100, and the assembly jig is fixed by the fixing part 400. Subsequently, under the action of the assembly part 500, the key is pushed to the assembly position of the watch case to complete the assembly of the watch case and the key. The whole process has a low degree of manual participation and can improve the assembly efficiency.
[0053] Among them, the fixing part 400 includes a pressing cylinder. A lower pressing plate 410 is arranged at the end of the piston rod of the pressing cylinder. The lower pressing plate 410 is above the assembly jig, and the lower pressing plate 410 can cooperate with the assembly seat 200 to clamp and fix the upper and lower sides of the assembly jig. When the lower pressing plate 410 fixes the assembly jig, it is necessary to avoid blocking the mounting hole 41. The fixing part 400 further includes two first spinning cylinders 420. The two first spinning cylinders 420 are respectively on the left and right sides of the assembly jig. After the rotating ends of the two first spinning cylinders 420 rotate, they can be attached to the other side of the assembly jig. Under the combined action of the two first spinning cylinders 420 and the frame 100, the clamping and fixing of the front and rear sides of the assembly jig can be completed.
[0054] In addition, the assembly part 500 includes a number of assembly cylinders 510. The number of assembly cylinders 510 is set according to the number of mounting holes 41. A connecting column 520 is arranged at the end of any one assembly cylinder 510. An assembly ejector pin 530 is detachably arranged coaxially on the connecting column 520 to facilitate the replacement of the model of the assembly ejector pin 530. The assembly ejector pin 530 can push the key to move under the action of the assembly cylinder 510 to complete the assembly.
[0055] Further, the assembly unit 500 further includes a plurality of limiting blocks 540. Limiting holes are formed in the limiting blocks 540. The assembly ejector pin 530 is adapted to the limiting holes, and the assembly ejector pin 530 can be slidably disposed in the limiting holes. The diameter of the connecting column 520 is greater than the diameter of the limiting holes, so as to limit the stroke of the assembly cylinder 510, and thus the pressing force applied by the assembly cylinder 510 can be controlled during the assembly process, so as to avoid damage to the button or the watch case due to excessive pressing force during the assembly process, and further improve the safety performance.
[0056] Based on the above, please refer to Figures 2 to 6 In this embodiment, a button assembly jig is further proposed, which includes a base 1, a locking part 2, an unlocking part 3 and an upper cover 4. The locking part 2 is disposed on the base 1, and the locking part 2 has a locking state of pressing outward from the inside of the inner ring of the watch case to support the inner ring of the watch case, and an unlocking state of contacting and pressing against the inner ring of the watch case to separate from each other; the unlocking part 3 cooperates with the locking part 2 to enable the locking part 2 to switch between the locking state and the unlocking state; the upper cover 4 is connected to the base 1 and covers the top of the watch case. The inner peripheral wall of the upper cover 4 can fit with the outer ring of the watch case. The upper cover 4 has a plurality of mounting holes 41 for accommodating buttons, and the mounting holes 41 are directly opposite to the mounting positions. It can be understood that through the cooperation of the unlocking part 3 and the locking part 2, the watch case can be fixed on the base 1. By covering the upper cover 4 on the top of the watch case and making the mounting holes 41 directly opposite to the mounting positions, during assembly, the button is placed in the mounting hole 41, and the alignment between the button and the watch case can be completed, thereby improving the alignment efficiency between the button and the watch case, and ensuring the alignment accuracy between the button and the watch case, and further improving the assembly efficiency of the button.
[0057] Further, a plurality of notches are provided on the inner side wall of the inner ring; the button assembly jig 300 further includes a positioning part 5, and the positioning part 5 is disposed on the base 1 and is used for positioning the notches. It can be understood that when placing the watch case, through the cooperation of the notches and the positioning part 5, the positioning accuracy of the watch case can be ensured, so as to further ensure the positioning accuracy between the installation position of the watch case and the mounting holes 41, and the cooperation between the notches and the positioning part 5 can also prevent the watch case from rotating when the locking part 2 locks the watch case.
[0058] Exemplarily, the positioning part 5 includes a plurality of positioning blocks. The positions and shapes of the positioning blocks are set according to the shape of the inner ring of the watch case. The plurality of positioning blocks are detachably disposed on the base 1, so that different-shaped positioning blocks can be replaced according to different models of watch cases, thereby improving the applicability of the assembly jig.
[0059] In this embodiment, the area of the upper cover 4 is smaller than that of the base 1, and the contour shape of the side surface of the upper cover 4 facing away from the mounting hole 41 is the same as the contour shape of one side surface of the base 1. It can be understood that before placing the upper cover 4, the side surfaces of the upper cover 4 and the base 1 with the same contour shape are facing the same side. When placing, it is necessary to ensure that the two side surfaces of the upper cover 4 and the base 1 are placed flush. Such a setting not only facilitates determining the placement posture of the upper cover 4 so as to accurately align the mounting hole 41 with the mounting position, but also facilitates placing the entire assembly jig stably on the assembly seat 200 to ensure the stability during the assembly process.
[0060] In addition, the shape of the base 1 is preferably an axisymmetric figure, that is, the contour shapes of the opposite side surfaces of the base 1 are both the same as the contour shape of the side surface of the upper cover 4 facing away from the mounting hole 41. Thus, when assembling the mounting positions on different sides of the watch case, only the upper cover 4 needs to be replaced, and it is not necessary to flip the position of the watch case. Such a setting can further improve the assembly efficiency of the button.
[0061] Furthermore, positioning pins for positioning the upper cover 4 are provided on the base 1, which can further ensure the positioning accuracy between the upper cover 4 and the base 1. After the upper cover 4 is placed, the base 1 and the upper cover 4 are fixed by a plurality of bolts.
[0062] In this embodiment, the locking part 2 includes a plurality of locking mechanisms 21, and the plurality of locking mechanisms 21 support the inner ring of the watch case along different radial directions of the watch case. It can be understood that the plurality of locking mechanisms 21 can apply supporting forces in different directions to the watch case, so as to further ensure that the watch case is always in a locked state to ensure the alignment accuracy between the mounting hole 41 and the mounting position.
[0063] Among them, the plurality of locking mechanisms 21 are stacked along the height direction. It can be understood that since the area of the inner ring of the watch case is limited, the stacked plurality of locking mechanisms 21 can relatively reduce the occupied area of the locking part 2.
[0064] Specifically, a receiving cavity 11 is provided at the top of the base 1, and the receiving cavity 11 has an opening; the locking mechanism 21 includes a locking member 211 and a compression spring 212: the locking member 211 is slidably arranged in the receiving cavity 11, and the locking end of the locking member 211 can pass through the opening; the compression spring 212 is compressively arranged between the locking member 211 and the cavity wall of the receiving cavity 11 so that the locking member 211 remains in contact with the inner ring. It can be understood that when the locking member 211 is in the locked state, the compression spring 212 has elastic potential energy to push the locking member 211 to move, so that the locking member 211 is in contact with the inner ring. When the locking member 211 is in the unlocked state, the unlocking part 3 can control the compression of the compression spring 212, so that the locking member 211 is separated from the inner ring to facilitate placing or removing the watch case.
[0065] Exemplarily, two locking mechanisms 21 are taken as examples for elaboration herein. The base 1 includes a bearing body 12 and a housing 13. A receiving groove is formed in the bearing body 12. The housing 13 is fixed to the bearing body 12 and cooperates with the bearing body 12 to form a receiving cavity 11 with two openings. The two openings face different directions, preferably perpendicular directions. The two locking mechanisms 21 are stacked in the height direction in the receiving cavity 11, and the two locking members 211 can extend out from the corresponding openings respectively. Among them, in the upper locking mechanism 21, the locking member 211 can be slidably connected to the housing 13, and the compression spring 212 is compressively arranged between the housing 13 and the corresponding locking member 211. In the lower locking mechanism 21, the locking member 211 can be slidably connected to the receiving groove, and the compression spring 212 is compressively arranged between the groove wall of the receiving groove and the corresponding locking member 211.
[0066] Furthermore, the part of the locking end of the locking member 211 that contacts the inner ring is profiled. With such a setting, it can be avoided that the locking end and the inner ring are disengaged when they are in contact, thereby further avoiding the offset of the watch case during the assembly of the button, and further ensuring the assembly effect of the button.
[0067] In this embodiment, the unlocking part 3 includes a carrier 31 and a plurality of unlocking mechanisms 32. The carrier 31 is used to carry and fix the base 1; the plurality of unlocking mechanisms 32 are all arranged on the carrier 31, and the plurality of unlocking mechanisms 32 are arranged in one-to-one correspondence with the plurality of locking mechanisms 21. It can be understood that a fixing station for placing the base 1 is provided on the carrier 31. After the base 1 is placed on the carrier 31, the plurality of unlocking mechanisms 32 can be arranged in one-to-one correspondence with the plurality of locking members 211, so as to facilitate the switching of the locking members 211 between the locked state and the unlocked state.
[0068] Among them, a plurality of positioning pins are provided on the carrier 31. The plurality of positioning pins are used to position the base 1, and after the base 1 is positioned, the horizontal movement of the base 1 can be avoided, so as to further ensure the accuracy and stability of the unlocking mechanism 32 during the unlocking process.
[0069] Specifically, the unlocking mechanism 32 includes an unlocking cylinder 321. The end of the piston rod of the unlocking cylinder 321 can extend into the interior of the receiving cavity 11 to push against the locking member 211 to move. It can be understood that when placing the watch case, the piston rod of the unlocking cylinder 321 extends and extends into the interior of the receiving cavity 11, and then pushes against the locking member 211 to move. During the movement of the locking member 211, the compression spring 212 can be compressed. After the watch case is placed, the piston rod of the unlocking cylinder 321 resets. Under the action of the elastic potential energy of the compression spring 212, the locking member 211 can be reset, so as to be in contact with the inner ring to complete the locking of the locking member 211.
[0070] Among them, an unlocking hole 14 facing the locking member 211 is provided on the base 1. The unlocking hole 14 communicates with the accommodating cavity 11. During the unlocking process, the piston rod of the unlocking cylinder 321 can extend from the unlocking hole 14 into the interior of the accommodating cavity 11.
[0071] Furthermore, the unlocking mechanism 32 further includes a guiding block 322. A guiding hole is formed in the guiding block 322. The guiding hole faces the unlocking hole 14. The guiding block 322 is arranged on the moving path of the piston rod of the unlocking cylinder 321 and is slidably arranged inside the guiding hole. With such a setting, the moving accuracy of the piston rod of the unlocking cylinder 321 can be ensured.
[0072] Among them, a plurality of guiding blocks 322 can form a fixing station for fixing the base 1. The side wall of any guiding block 322 facing the base 1 is arranged in imitation of the side surface of the base 1, so as to ensure that the guiding block 322 can be attached to the base 1 when the base 1 is placed, thereby further improving the position accuracy of the base 1 during the placement process.
[0073] In this embodiment, the button assembly jig 300 further includes a detection part 6. The detection part 6 is used to detect the installation state between the upper cover 4 and the base 1. It can be understood that after the upper cover 4 is installed, in order to ensure the installation state between the base 1 and the upper cover 4, so as to further ensure the alignment accuracy between the installation hole 41 and the installation position.
[0074] Exemplarily, the detection part 6 is a second spinning cylinder arranged on the carrier 31. After the upper cover 4 is installed, by rotating the rotating end of the second spinning cylinder, the rotating end of the second spinning cylinder can be rotated from the top of the upper cover 4 and can be kept in contact with the top of the upper cover 4 to detect the levelness of the upper cover 4. Of course, in some other feasible embodiments, the detection part 6 can also be other existing detection parts 6, which will not be elaborated here.
[0075] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
