[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] like Figure 1-4As shown, a watch bottom cover screwing device comprises a bracket 1, a rotating shaft 2, a sliding sleeve 3, a rotating motor 4 and a lifting motor 5. The rotating shaft 2 is vertically arranged at one end of the bracket 1 and is rotatably connected to the bracket 1. The sliding sleeve 3 is sleeved on the rotating shaft 2 and can slide along the axial direction of the rotating shaft 2. The outer wall of the sliding sleeve 3 is evenly distributed with a plurality of tooth grooves 31 along the axial direction. The tooth grooves 31 are all arranged along the circumferential direction of the sliding sleeve 3. A rubber block 32 is arranged at the bottom end of the sliding sleeve 3. The rotating motor 4 and the lifting motor 5 are both arranged on the bracket 1. The rotating motor 4 is used to drive the rotating shaft 2 to drive the sliding sleeve 3 to rotate synchronously. A gear 51 is arranged at the output end of the lifting motor 5. The gear 51 is meshed with the tooth groove 31. When in use, the watch is firstly rotated. The case is clamped on a special fixture and placed under the rubber block 32. The bottom cover to be screwed is aligned and placed at the opening of the watch case. Then the watch bottom cover screwing device can be started. At this time, the lifting motor 5 will drive the sliding sleeve 3 to slide down through the transmission of the gear 51 and the tooth groove 31, so that the rubber block 32 abuts against the bottom cover, and the rubber block 32 will press the bottom cover down. At the same time, the rotating motor 4 will drive the rotating shaft 2 to rotate, and drive the sliding sleeve 3 to rotate synchronously through the rotating shaft 2, so as to utilize the friction resistance between the rubber block 32 and the bottom cover to drive the bottom cover to be screwed on the watch case, thereby completing the screwing operation of the bottom cover and the watch case, replacing manual screwing of the bottom cover, reducing operating errors, and improving the assembly efficiency of the bottom cover.

[0028] In one embodiment, the output end of the rotary motor 4 is coaxially connected to the rotary shaft 2 (not shown in the drawings).

[0029] Specifically, when the sleeve 3 rotates, the gear 51 will slide along the tooth groove 31 to avoid interfering with the rotation of the sleeve 3; the rotating motor 4 and the lifting motor 5 can be controlled by corresponding control chips, which is a prior art and will not be explained in this embodiment.

[0030] Furthermore, a slider 21 is provided on the side wall of the rotating shaft 2, and a slide groove 33 is provided on the inner side of the sliding sleeve 3 along the axial direction. The slider 21 is slidably connected in the slide groove 33. When the rotating shaft 2 rotates, the sliding sleeve 3 can be driven to rotate synchronously through the connection between the slider 21 and the slide groove 33. When the sliding sleeve 3 slides up and down, the slider 21 can slide adaptively along the slide groove 33 to avoid interfering with the axial sliding of the sliding sleeve 3.

[0031] Furthermore, the output end of the rotating motor 4 is connected to the rotating shaft 2 through a belt 6. The belt 6 has a certain elasticity. The rubber block 32 is driven to rotate by the belt to avoid overload and prevent the bottom cover or the case from being damaged.

[0032] Furthermore, the bracket 1 includes a column 11 and a mounting block 12, the mounting block 12 is horizontally fixed on the top of the column 11, the sliding sleeve 3 is vertically sleeved on one end of the mounting block 12 and is slidably connected to the mounting block 12, the bottom end of the sliding sleeve 3 passes over the bottom of the mounting block 12, the rotating shaft 2 is correspondingly arranged with the sliding sleeve 3, the top end of the rotating shaft 2 passes over the top of the mounting block 12, and is rotatably connected to the mounting block 12.

[0033] Furthermore, the watch bottom cover screwing device also includes a barrier 7, which is composed of a plurality of baffles. The barrier 7 is arranged horizontally around the bracket 1 to enclose the bracket 1, the rotating shaft 2, the sliding sleeve 3, the rotating motor 4 and the lifting motor 5. The barrier 7 can prevent foreign objects from knocking against the bracket 1, the rotating shaft 2, the sliding sleeve 3, the rotating motor 4 and the lifting motor 5, thereby playing a protective role and extending the service life of the watch bottom cover screwing device.

[0034] Furthermore, the watch bottom cover screwing device also includes a shell 8, and the enclosure 7, the bracket 1, the rotating shaft 2, the sliding sleeve 3, the rotating motor 4 and the lifting motor 5 are all arranged in the shell 8. An assembly position 81 is provided on one side of the shell 8, and an avoidance opening 82 is provided above the assembly position 81 for the bottom end of the sliding sleeve 3 to extend out of the shell 8.

[0035] Furthermore, a controller 83 is provided on one side of the shell 8 , and the controller 83 is electrically connected to the rotating motor 4 and the lifting motor 5 , respectively. The user can control the operation of the lifting motor 5 and the rotating motor 4 through the controller 83 , thereby controlling the lifting and rotation of the rubber block 32 .

[0036] Furthermore, the watch bottom cover screwing device also includes an upper cover 85. The top of the shell 8 is provided with an operating port 84 connected to its inner cavity. The upper cover 85 can detachably cover the operating port 84. The user can remove the upper cover 85 to inspect the components inside the shell 8 to facilitate daily maintenance of the watch bottom cover screwing device.

[0037] Furthermore, a case clamp 9 is fixedly provided on the assembly position 81 so that the case can be fixedly clamped under the rubber block 32 by the case clamp 9, which is convenient for the subsequent alignment and screwing of the bottom cover. The case clamp 9 can be purchased through market channels and will not be elaborated in this embodiment.

[0038] Furthermore, the rubber block 32 is made of rubber, which has good elasticity and deformation recovery ability. The contact between the rubber block 32 and the bottom cover can avoid damage to the bottom cover. Meanwhile, the rubber is inexpensive and durable, and has good economic benefits.
