[0032] The support frame 100 includes a support base plate 110 and a U-shaped connecting plate 120 . The U-shaped connecting plate 120 is vertically arranged with respect to the support base plate 110 , and an open end of the U-shaped connecting plate 120 is connected with the support base plate 110 .

[0033] The bearing seat 200 is connected to a side of the supporting base plate 110 facing the U-shaped connecting plate 120 . A fixing groove 201 is formed at one end of the bearing seat 200 away from the supporting base plate 110 . The fixing groove 201 is used to place the button to be installed.

[0034] The extrusion mechanism 300 includes an extrusion cylinder 310, a sliding block 320, and at least two sliding rods 330. The extrusion cylinder 310 is connected to the sealed end of the U-shaped connecting plate 120. In the present embodiment, the extrusion cylinder 310 is arranged on the side of the sealed end of the U-shaped connecting plate 120 facing away from the supporting base plate 110. The telescopic rod of the extrusion cylinder 310 is drivingly connected to the sliding block 320. One end of each sliding rod 330 is connected to the supporting base plate 110, and the other end is connected to the sealed end of the U-shaped connecting plate 120. A plurality of sliding through holes 301 are provided on the sliding block 320, and each sliding rod 330 is inserted into a sliding through hole 301 and is slidably connected to the sliding block 320.

[0035] The rotating mechanism 400 includes a rotating motor 410 and a rotating shaft 420. The rotating motor 410 is fixedly connected to the sliding block 320. The rotating motor 410 is drivingly connected to the rotating shaft 420. The sliding block 320 is provided with a rotating hole 302. The rotating hole 302 penetrates the sliding block 320. The rotating shaft 420 is penetrated in the rotating hole 302 and is rotatably connected to the sliding block 320. In this embodiment, the rotating mechanism 400 also includes a connecting plate 430 and a plurality of connecting columns 440. The rotating motor 410 is connected to the connecting plate 430. The connecting plate 430 is connected to the sliding block 320 through each connecting column 440 to increase the stability of the connection between the rotating motor 410 and the sliding block 320. Further, each connecting column 440 is evenly arranged on the connecting plate 430 to further increase the stability of the connection between the rotating motor 410 and the sliding block 320.

[0036] The clamping mechanism 500 includes a fixed column 510, a pneumatic finger 520 and two clamping plates 530. The fixed column 510 is connected to the side of the sliding block 320 facing away from the rotating motor 410, and is used to hang the watch case to be processed. The pneumatic finger 520 is connected to the end of the rotating shaft 420 away from the rotating motor 410, and each clamping claw of the pneumatic finger 520 is connected to a clamping plate 530. The side of the two clamping plates 530 close to each other is an arc surface to adapt to the shape of the watch case to be processed. The pneumatic finger 520 drives the two clamping plates 530 to move close to the fixed column 510 through the two clamping claws to clamp and fix the watch case to be processed.

[0037] The extrusion cylinder 310 drives the fixed column 510 by driving the sliding block 320 to drive the watch case to be processed to move closer to or away from the supporting base 200.

[0038] In order to increase the working stability of the extrusion mechanism 300, in one embodiment, the extrusion mechanism 300 also includes at least two linear bearings, and the sliding through hole 301 and the sliding rod 330 are both adapted to the linear bearings. Each linear bearing is arranged in a sliding through hole 301 and fixedly connected to the sliding block 320, and each sliding rod 330 is inserted in a linear bearing and slidably connected to the linear bearing. The linear bearing avoids direct contact between the sliding rod 330 and the inner wall of the sliding through hole 301, avoids mutual wear between the sliding rod 330 and the inner wall of the sliding through hole 301, reduces the friction generated by the sliding block 320 moving up and down relative to the sliding rod 330, and improves the smoothness of the sliding block 320 moving up and down relative to the sliding rod 330. In this way, the linear bearing increases the working stability of the extrusion mechanism 300, thereby increasing the working stability of the case button installation device 10.

[0039] In order to increase the working stability of the rotating mechanism 400, in one embodiment, the rotating mechanism 400 further includes a rolling bearing, and the outer ring and the inner ring of the rolling bearing are rotatably connected through a plurality of balls. The rotating hole 302 and the rotating shaft 420 are both adapted to the rolling bearing, the rolling bearing is arranged in the rotating hole 302, the outer ring of the rolling bearing is fixedly connected to the side wall of the rotating hole 302, and the rotating shaft 420 is inserted into the inner ring of the rolling bearing and fixedly connected to the inner ring of the rolling bearing. The rolling bearing avoids direct contact between the rotating shaft 420 and the inner wall of the rotating hole 302, avoids mutual wear between the rotating shaft 420 and the inner wall of the rotating hole 302, reduces the friction force generated by the rotation of the rotating shaft 420 relative to the sliding block 320, and improves the smoothness of the rotation of the rotating shaft 420 relative to the sliding block 320. In this way, the linear bearing increases the working stability of the rotating mechanism 400, thereby increasing the working stability of the case button installation device 10.

[0040] In order to increase the working stability of the clamping mechanism 500, in one embodiment, an anti-skid pad is provided on the arc surface of each clamping plate 530, and the anti-skid pad increases the anti-skid performance of the clamping plate 530 to increase the friction between the clamping plate 530 and the watch case to be processed, thereby increasing the stability of the clamping mechanism 500 clamping the watch case to be processed. In one embodiment, the anti-skid pad is a hard rubber pad, which has certain elasticity, good toughness and excellent anti-skid performance, and can increase the friction between the clamping plate 530 and the watch case to be processed while protecting the watch case to be processed. In another embodiment, the anti-skid pad is a hard silicone pad. In another embodiment, anti-skid lines are provided on the arc surface of each clamping plate 530. In this way, the friction between the clamping plate 530 and the watch case to be processed is increased, thereby increasing the working stability of the clamping mechanism 500.

[0041] During operation, the above-mentioned watch case button installation device 10 places the button to be installed in the fixed groove 201 provided in the support seat 200, and sets the watch case to be processed on the fixed column 510. The pneumatic finger 520 drives the two clamps 530 to move close to the fixed column 510 through the two clamps to clamp and fix the watch case to be processed. The rotating motor 410 drives the pneumatic finger 520 to rotate through the rotating shaft 420, thereby driving the watch case to be processed to rotate, so that the button hole of the watch case to be processed is aligned with the button to be installed in the fixed groove 201. The extrusion cylinder 310 drives the fixed column 510 to drive the watch case to be processed to move close to the support seat 200 by driving the sliding block 320. The button to be installed in the fixed groove 201 is squeezed into the button hole of the watch case to be processed, and a button is installed in each button hole of the watch case to be processed in this cycle. After all the buttons are installed in the button holes of the watch case to be processed, the pneumatic finger 520 drives the two clamping plates 530 to move away from the fixing column 510 through the two clamping claws, so as to remove the installed watch case from the fixing column 510, so as to install the buttons on the next watch case to be processed. The watch case button installation device 10 has high efficiency, low error and low cost.

[0042] See also Figure 4 In one embodiment, in order to prevent the case button installation device 10 from applying excessive force to the extrusion cylinder 310 during operation to damage the bearing seat 200 and the case to be processed. The bearing seat 200 includes a base 210, a compression spring 220, a receiving column 230 and a receiving block 240. The base 210 is connected to the supporting base plate 110, and a buffer groove 202 is provided on the base 210. The compression spring 220 and the receiving column 230 are both adapted to the buffer groove 202. The compression spring 220 is accommodated in the buffer groove 202 and abuts against the bottom of the buffer groove 202. The receiving column 230 is partially inserted in the buffer groove 202 and is slidably connected to the base 210. One end of the receiving column 230 inserted in the buffer groove 202 abuts against the compression spring 220. One end of the receiving column 230 exposed in the buffer groove 202 is connected to the receiving block 240. The fixing groove 201 is provided in the receiving block 240. The extrusion cylinder 310 drives the fixed column 510 to drive the watch case to be processed to move close to the receiving block 240 by driving the sliding block 320. The downward movement distance of the watch case to be processed after contacting the receiving block 240 is less than the maximum elastic deformation of the compression spring 220. In other words, the force for squeezing the key to be installed into the key hole of the watch case to be processed is the elastic force of the compression spring 220. In this way, the extrusion cylinder 310 is prevented from applying excessive force to the bearing seat 200 and the watch case to be processed during the operation of the watch case key installation device 10, thereby increasing the working stability of the watch case key installation device 10.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
