Description

Technical Field

[0001] The invention relates to the technical field of watch production, and in particular to a watch knob assembly device. Background Art

[0002] A watch knob, commonly known as a crown, is a rotatable button on the side of a watch. It is generally composed of parts such as an outer cap and a stem. It is mainly used to set the time and date, and for winding some mechanical watches. The stem is a winding tool directly connected to the movement.

[0003] After the assembly of some watch movements is completed, the stem will be directly connected to the movement, and then assembled with other parts, and finally the outer cap will be installed on the stem connected to the movement. When assembling the outer cap, an outer cap clamp will be used to screw the outer cap onto the stem. The existing outer cap clamp requires staff to place the outer cap in the clamp when in use, and only one outer cap can be placed at a time, and then the stem must be clamped and fixed with a clamp before the outer cap clamp can be used to screw the outer cap onto the stem. The process is cumbersome and time-consuming, which greatly reduces the assembly efficiency of the outer cap and the stem. At the same time, since the stem is thin and has low rigidity, when the staff uses the clamp to fix the stem, the stem is easily bent and deformed by the clamp, resulting in the stem being unable to adjust the time and date of the watch normally, reducing the quality of the assembled watch.

[0004] Furthermore, since the existing outer cap clamp does not have a calibration and alignment function, when the staff holds the outer cap clamp to assemble the outer cap and the stem, the outer cap is likely to push the stem off, causing wear on the stem and the watch case. At the same time, when the stem is offset, it is easy to tilt the movement, causing damage to the inside of the movement, which greatly reduces the quality of the assembled watch. Summary of the invention

[0005] In order to overcome the shortcomings of low assembly efficiency when using the existing outer cap clamp to assemble the outer cap and the stem, the stem is prone to bending and damage during the assembly process, which reduces the quality of the assembled watch, the present invention provides a watch knob assembly device.

[0009] Further description, it also includes a connector and an adjustment ring; the connector is slidably connected to the clamp tube; the adjustment ring is fixedly connected to the rear side of the connector; a plurality of adjustment parts are arranged on the adjustment ring; each adjustment part contacts the side of the corresponding rotating block away from the clamp tube.

[0010] Further explanation: the bottom of the fixing seat is arranged in an inclined state with the front higher and the back lower.

[0011] Further explanation: the feed port on the clamp tube is configured as a flared structure.

[0012] Further description, it also includes reinforcement blocks; a plurality of reinforcement blocks for reinforcing the watch case are fixedly connected to the connecting rod.

[0013] Further description, it also includes a fixed block and oil-absorbing cotton; the fixed block is fixedly connected to the lower side of the connecting rod; and the fixed block is connected to the oil-absorbing cotton for storing green oil.

[0015] Further description, it also includes a support plate; a plurality of movable grooves are opened on the fixed seat; a support plate for protecting the watch lens is slidably connected to the fixed seat; and the support plate slides in the movable grooves.

[0016] The beneficial effects of the present invention are as follows: the present invention realizes the outer cap being screwed onto the handle shaft through the clamp tube to complete the assembly of the outer cap, which not only improves the assembly efficiency of the outer cap, but also improves the accuracy of the connection between the outer cap and the handle shaft;

[0017] The reinforcing block is driven to fit onto the limiting part by the connecting rod, and the fixture tube is calibrated, which improves the subsequent docking accuracy of the outer cap and the stem. At the same time, the limiting and fixing effect of the watch case is enhanced to prevent the watch case from shifting up and down on the fixing seat when assembling the outer cap, and further improve the docking accuracy of the outer cap and the stem.

[0018] The clamp tube drives the next outer cap to be assembled to move to contact with the oil-absorbing cotton, so as to realize convenient oiling of the outer cap. The staff does not need to use other oiling tools to oil the outer cap, which further improves the efficiency of outer cap assembly.

[0019] By using the push rod to push the support plate upward, the assembled watch case is lifted up, making it easier for workers to remove the assembled watch case. At the same time, the support plate prevents the push rod from directly pushing it to contact the lens on the watch case, preventing the watch case lens from being scratched by the friction of the push rod, thereby enhancing the protection of the watch case lens.

[0031] It also includes a connecting rod 2, a clamp tube 3, a fixing assembly and a limiting assembly; a limiting portion 1001 is detachably connected to the fixing seat 1; the fixing seat 1 is rotatably connected to the connecting rod 2; the clamp tube 3 is movably connected to the connecting rod 2; a protrusion 6001 is provided on the outer side of the outer cap 6; a limiting groove 3001 is provided inside the clamp tube 3; a feed port 3002 is provided on the clamp tube 3; the feed port 3002 is connected to the limiting groove 3001; a fixing assembly is provided on the connecting rod 2; and a limiting assembly is provided on the clamp tube 3.

[0032] The fixing assembly includes a locking block 101 and a clamping rod 102; two sliding grooves 2001 which are symmetrical on the left and right are provided on the connecting rod 2; the locking block 101 is slidably connected to the connecting rod 2; the locking block 101 slides in the sliding groove 2001; a flared portion 10101 is provided on the locking block 101; a locking groove 10102 is provided on the locking block 101; the locking groove 10102 is located on the rear side of the flared portion 10101; two clamping rods 102 which are symmetrical on the left and right are rotatably connected to the connecting rod 2 through a torsion spring; the two clamping rods 102 are in an eight-shaped shape; a threaded groove 10201 is provided on each clamping rod 102.

[0033] The limiting assembly includes a rotating block 201, a clamping block 202 and a stopper 203; two rotating blocks 201 that are symmetrical on the left and right are rotatably connected to the clamp tube 3; a clamping block 202 is rotatably connected to the rear side of each rotating block 201; a stopper 203 is rotatably connected to the front side of each rotating block 201; and each stopper 203 penetrates into the clamp tube 3.

[0034] It also includes a connector 204 and an adjustment ring 205; the connector 204 is slidably connected to the clamp tube 3; the adjustment ring 205 is fixedly connected to the rear side of the connector 204; the adjustment ring 205 is provided with two left-right symmetrical adjustment parts 20501; each adjustment part 20501 is in contact with the side of the corresponding rotating block 201 away from the clamp tube 3.

[0035] Furthermore, in order to make the balance wheel 5003 rotate to the side away from the stem shaft 5004 and prevent the balance wheel 5003 from blocking the normal installation of the outer cap 6, the bottom of the fixing seat 1 is set in an inclined state with the front higher and the back lower.

[0036] Furthermore, in order to facilitate the outer cap 6 to enter the fixture tube 3 and improve the efficiency of loading the outer cap 6 into the fixture tube 3, the feed port 3002 on the fixture tube 3 is configured as a flared structure.

[0037] It also includes a reinforcement block 4; two reinforcement blocks 4 are fixedly connected to the connecting rod 2 in a bilaterally symmetrical manner.

[0038] It also includes a fixing block 301 and oil-absorbing cotton 302 ; the fixing block 301 is fixedly connected to the lower side of the connecting rod 2 ; and the oil-absorbing cotton 302 is detachably connected inside the fixing block 301 .

[0039] When assembling the outer cap 6 onto the stem 5004 connected to the movement 5002, the staff needs to first place a single outer cap 6 in a clamp, and then use a clamp to clamp and fix the stem 5004, and then use the clamp to screw the outer cap 6 onto the stem 5004. The process is cumbersome and time-consuming, and the clamp may damage the stem 5004, resulting in the stem 5004 being unable to be used normally. The present invention loads multiple outer caps 6 through a clamp tube 3, and uses a fixing seat 1 to limit and fix the watch case 5, so that the clamp tube 3 is easy to calibrate and align, thereby solving the problems of low assembly efficiency of the outer cap 6 and reduced docking accuracy between the outer cap 6 and the stem 5004. The specific process is as follows:

[0040] When assembling the outer cap 6 onto the stem 5004 connected to the movement 5002, the staff first loads multiple outer caps 6 into the vertical clamp tube 3 from the feed port 3002, and limits the protrusion 6001 by the limiting groove 3001. At the same time, the other end of the clamp tube 3 is blocked by the clamp block 202 to prevent the outer cap 6 from falling from the other end of the clamp tube 3. After the outer cap 6 is loaded, the staff first installs the limiting part 1001 corresponding to the model of the watch case 5 on the fixing seat 1, and then places the watch case 5 on the fixing seat 1, and makes the strap groove 5001 snap into the corresponding limiting part 1001 for limiting and fixing. It should be noted that the following orientation descriptions are all based on Figure 1 For reference, the feed port 3002 is the front side, and the limit portion 1001 is the left side. Then the staff pulls the vertical clamp tube 3 upward, and at the same time rotates the clamp tube 3 together with the connecting rod 2 forward to Figure 1 In the horizontal state shown, during this process, the reinforcing block 4 is driven by the connecting rod 2 to rotate forward and fit onto the limiting portion 1001, and the reinforcing block 4 is brought into contact with the watch case 5, so as to calibrate the clamp tube 3, so that the outer cap 6 in the clamp tube 3 is aligned with the stem shaft 5004. Compared with the existing situation where the outer cap 6 pushes the stem shaft 5004 to offset and damage due to manual calibration and alignment, the subsequent docking accuracy of the outer cap 6 and the stem shaft 5004 is improved, and at the same time, the limiting and fixing effect of the watch case 5 is enhanced, preventing the watch case 5 from shifting up and down on the fixing seat 1 when assembling the outer cap 6, and further improving the docking accuracy of the outer cap 6 and the stem shaft 5004.

[0041] When the clamp tube 3 drives the connecting rod 2 to rotate forward to a horizontal state, the connecting rod 2 drives the two clamping rods 102 in an eight-shaped shape to rotate together until they are stuck in the gap between the watch case 5 and the movement 5002, and the stem 5004 is located between the two clamping rods 102. Then the staff slides the locking block 101 forward in the sliding groove 2001, so that the flared portion 10101 rotates the bottom of the two clamping rods 102 in an eight-shaped shape toward the middle and contracts, and at the same time compresses the torsion spring between the clamping rod 102 and the connecting rod 2. As the locking block 101 continues to slide forward in the sliding groove 2001, the locking groove 10102 limits and fixes the two clamping rods 102 to prevent the two clamping rods 102 from pushing the locking block 101 back and separating them. Figure 3 As shown, the clamping rod 102 is used to clamp and fix the handle shaft 5004 through the locking block 101, and at the same time, the threaded groove 10201 is engaged with the thread on the handle shaft 5004. Compared with the existing situation where the handle shaft 5004 is clamped and fixed by pliers, which makes the handle shaft 5004 easily bent and deformed by the pliers, the protection effect of the handle shaft 5004 during the assembly process is improved, and the clamping and fixing effect of the clamping rod 102 on the handle shaft 5004 is enhanced, which facilitates the subsequent screwing of the outer cap 6 and the handle shaft 5004.

[0042] After the clamp rod 102 fixes the handle shaft 5004, the staff pushes the clamp tube 3 backward, and the clamp drives the outer cap 6 to contact the handle shaft 5004, and then pulls the connector 204 together with the adjusting ring 205 forward, so that the adjusting part 20501 moves forward and squeezes the front part of the rotating block 201, and then the rotating block 201 drives the clamping block 202 to move away from the center of the clamp tube 3, thereby releasing the obstruction of the outer cap 6 at the rear end of the clamp tube 3 by the clamping block 202. While the rotating block 201 rotates, it drives the stopper 203 to move toward the center of the clamp tube 3 to block and limit the next outer cap 6. Then the staff rotates the clamp tube 3 and limits the protrusion 6001 through the limiting groove 3001, so that the outer cap 6 rotates together with the clamp tube 3, and then the outer cap 6 is screwed onto the handle shaft 5004, completing the assembly of the outer cap 6, which not only improves the assembly efficiency of the outer cap 6, but also improves the accuracy of the docking between the outer cap 6 and the handle shaft 5004.

[0043] When the outer cap 6 is assembled, the staff pulls the clamp tube 3 forward to move the clamp tube 3 away from the watch case 5, and then pushes the connector 204 together with the adjusting ring 205 backward to move the adjusting portion 20501 backward and squeeze the rear part of the rotating block 201, so that the rotating block 201 drives the clamp block 202 to move toward the center of the clamp tube 3, so that the clamp block 202 blocks the rear end of the clamp tube 3 again, and the rotating block 201 rotates while driving the stop block 203 to move away from the center of the clamp tube 3, releasing the next outer cap 6. The staff then slides the locking block 101 backward in the sliding groove 2001 to release the expansion portion 10101 from the clamping rod 102, so that the clamping rod 102 is separated from the stem shaft 5004 under the elastic force of the torsion spring. After the clamping rod 102 is separated from the stem shaft 5004, the staff rotates the clamp tube 3 together with the connecting rod 2 upward to a vertical state, so that the connecting rod 2 drives the reinforcement block 4 to separate from the reinforcement block 4, and then removes the watch case 5 from the fixing seat 1, ready to place the next watch case 5 to be assembled.

[0044] When installing the outer cap 6, green oil needs to be added to each outer cap 6 to fill the small gap between the outer cap 6 and the watch case 5 and to lubricate the outer cap 6. However, when adding green oil to each outer cap 6, the staff can only manually apply oil to each outer cap 6 with the help of tools. The process is cumbersome and time-consuming, which reduces the efficiency of installing the outer cap 6. The specific solution process is as follows:

[0045] When the staff rotates the clamp tube 3 together with the connecting rod 2 upward to a vertical state and prepares to place the next watch case 5 to be assembled, the staff moves the clamp tube 3 in the vertical state downward, so that the clamp tube 3 drives the outer cap 6 to be assembled to move to the fixed block 301, so that the outer cap 6 is in contact with the oil-absorbing cotton 302, thereby realizing convenient oiling of the outer cap 6. There is no need for the staff to use other oiling tools to oil the outer cap 6, which further improves the assembly efficiency of the outer cap 6.

[0046] Example 2

[0047] On the basis of Example 1, Figure 1 , Figure 2 and Figure 5 As shown, a push rod 401 is also included; the push rod 401 is fixedly connected to the rear side of the connecting rod 2.

[0048] It also includes a support plate 402; two movable grooves 1002 that are symmetrical to each other are opened on the fixed seat 1; the support plate 402 is slidably connected to the fixed seat 1; and the support plate 402 slides in the movable grooves 1002.

[0049] When the outer cap 6 is assembled, when the staff rotates the clamp tube 3 together with the connecting rod 2 upward to a vertical state, the connecting rod 2 drives the push rod 401 to rotate from the rear side of the fixing seat 1 to the middle of the fixing seat 1, and the push rod 401 lifts the assembled watch case 5 upward, so that the watch case 5 is separated from the limiting part 1001, which makes it convenient for the staff to remove the assembled watch case 5 and improves the convenience of cutting the watch case 5.

[0050] It is also considered that when the top rod 401 lifts the assembled watch case 5 upward, the end of the top rod 401 will rub against the lens of the watch case 5, causing scratches and wear on the lens of the watch case 5. The specific solution process is as follows:

[0051] When the connecting rod 2 drives the push rod 401 to rotate from the rear side of the fixing seat 1 to the middle of the fixing seat 1, the push rod 401 pushes the support plate 402 upward, so that the support plate 402 slides upward in the movable groove 1002, and the support plate 402 prevents the push rod 401 from directly pushing to contact the lens on the watch case 5, preventing the lens of the watch case 5 from being scratched by the friction of the push rod 401, thereby enhancing the protection effect of the lens of the watch case 5. After the watch case 5 is lifted up by the support plate 402, the staff removes the watch case 5 from the fixing seat 1 and prepares to place the next watch case 5 to be assembled.
