[0026] like Figure 2 , 3 As shown in FIG. 4 , the pressing mechanism 4 includes a mounting seat 41, which is mounted on the main body 1; a pressing cylinder 42 is mounted on the mounting seat 41, and the pressing cylinder 42 is connected to a pressing plate 44 that can perform elastic activities; a support plate 47 for placing the watch band 9 is provided in the mounting seat 41, and the pressing plate 44 is suspended above the support plate 47; the pressing cylinder 42 is connected to a push plate 43, and the push plate 43 is connected to the pressing plate 44 through a spring 46 and a guide post 45; the pressing plate 44 is connected and fixed to the guide post 45, and the guide post 45 is mounted on the pushing plate 43 through a linear bearing, and the spring 46 is sleeved on the guide post 45 and respectively resists the pushing plate 43 and the pressing plate 44. The pressing mechanism 4 has two sets of pressing plates 44. After the watch band 9 is placed on the support plate 47, the pressing cylinder 42 performs lifting and lowering movements, so that the pressing plate 44 performs pressing processing on the watch band 9. During the pressing process, due to the elastic effect of the spring 46, the pressing plate 44 has a buffering effect when pressing on the strap 9, thereby protecting the strap 9 and preventing the strap 9 from being damaged.

[0027] A side plate 411 is provided along the front end of the support plate 47, and a limit plate 48 is provided at the rear of the support plate 47. The side plate 411 and the limit plate 48 are relative to each other in front and back and are used to limit the watch strap 9 placed on the support plate 47; the limit plate 48 is connected to a screw rod 49, and the screw rod 49 is connected to a limit motor 410, and the limit motor 410 is installed at the tail end of the mounting seat 41. During the pressing process, when the watch strap 9 is displaced, the screw rod 49 is driven by the limit motor 410, and the screw rod 49 drives the limit plate 48 to extend forward to support the rear side of the watch strap 9, thereby solving the problem of the watch strap 9 moving out of position. A notch 412 for facilitating feeding is provided on the side plate 411, and the clamping mechanism 3 feeds the watch strap 9 into the pressing mechanism 4 through the notch 412. (The front and rear drive modules described later can drive the watch strap 9 to move forward and backward)

[0028] like Figure 5 , 6 As shown in Figures 7 and 8, the rolling mechanism 5 includes a support frame 51 and a roller group 52, and the roller group 52 is installed on the support frame 51. The roller group 52 includes an upper roller 521 and a lower roller 522 arranged in an upper and lower structure. At least one of the upper and lower rollers 521 and 522 is connected to a driving device to achieve rotation. There is a gap between the upper and lower rollers 521 and 522 for the strap 9 to pass through. When the strap 9 passes through the gap between the upper and lower rollers 521 and 522, it is rolled by the upper and lower rollers 521 and 522.

[0029] Upper and lower paper tape retracting mechanisms are installed on the support frame 51. The upper paper tape retracting mechanism includes an upper paper putting wheel 55 and an upper paper collecting wheel 54, and the lower paper tape retracting mechanism includes a lower paper putting wheel 57 and a lower paper collecting wheel 56. Paper tape rolls are placed on the upper paper putting wheel 55 and the lower paper putting wheel 57 respectively. The paper tape 10 led out from the upper paper putting wheel 55 and the lower paper putting wheel 57 respectively passes through the gap between the upper and lower rollers 521 and 522 and adheres to the upper and lower surfaces of the strap 9 respectively, and then is introduced into the upper and lower paper collecting wheels 54 and 56. This can protect the surface of the strap 9 and prevent it from being crushed.

[0030] A strap pushing mechanism and a feed plate 53 are provided on one side of the roller group 52, and the feed plate 53 is connected to the roller group 52; the strap pushing mechanism includes a pushing plate 58 and a pushing cylinder 59, and the pushing plate 58 is located on one side of the feed plate 53 and is connected to the pushing cylinder 59 to form a movable structure; a guide plate 581 is provided on the feed plate 53 near the pushing plate 58, and a guide hole 582 for the strap 9 to pass through is provided on the guide plate 581, and the pushing plate 58 is driven by the pushing cylinder 59 to push the strap 9 through the guide hole 582 and enter the gap between the upper and lower rollers 521 and 522 through the feed plate 53.

[0031] The clamping mechanism 3 includes a movable clamping jaw 37 and a fixed clamping jaw 38, wherein the fixed clamping jaw 38 is fixedly mounted on a lifting slide 39, and the movable clamping jaw 37 is mounted on a variable pitch slide 35, and the fixed clamping jaw 38 and the movable clamping jaw 37 are respectively connected with a clamping jaw cylinder 36 so as to realize opening and clamping; the variable pitch slide 35 is movably mounted on the lifting slide 39 and is connected with a variable pitch cylinder 36, and the variable pitch cylinder 34 is fixedly mounted on the lifting slide 39; the lifting slide 39 is mounted on a mounting plate 32 through a vertical lifting guide rail, and a driving motor 33 is mounted on the back of the mounting plate 32, and the driving motor 33 is connected to the lifting slide 39 to drive the lifting slide 39 to perform lifting movement; the mounting plate 32 is mounted on the front and rear drive modules, that is, it can drive the various components on the mounting plate 32 to realize forward and backward movement, and at the same time, the front and rear drive modules are mounted on a base plate 31, and the base plate 31 is mounted on the linear module. By driving the variable pitch slide plate 35 to move horizontally through the variable pitch cylinder 34, the distance between the movable clamping jaw 37 and the fixed clamping jaw 38 can be adjusted to adapt to the strap 9 whose length changes after being pressed.

[0032] The linear module includes a first linear module 71 and a second linear module 72. The first linear module 71 is arranged between the pressing mechanism 4 and the rolling mechanism 5, and the second linear module 72 is arranged on the outside of the rolling mechanism 5. A set of clamping mechanisms 3 are respectively arranged on the first linear module 71 and the second linear module 72. A collecting box 8 is arranged next to the main body 1. The second linear module 72 extends to the top of the collecting box 8. The collecting box 8 stores the watch strap 9 that has completed the pressing and rolling operation. After the clamping mechanism 3 on the second linear module 72 releases the watch strap 9, the watch strap 9 will automatically fall into the collecting box 8.

[0033] A strap pulling-out mechanism 6 is provided on the other side of the roller assembly 52, and the strap pulling-out mechanism 6 includes a fixed clamp seat 61, a movable guide rail 66 is installed above the fixed clamp seat 61, a clamping cylinder 65 is installed on the movable guide rail 66 through a slide seat 64, the clamping cylinder 65 is connected to a lifting plate 63, and the lifting plate 63 is connected to a movable clamp 62, and the movable clamp 62 is opposite to the fixed clamp seat 61 to form a structure for limiting one end of the strap 9.

[0034] The front end of the strap 9 moves under the squeezing action of the upper roller 521 and the lower roller 522, and then the movable clamp 62 and the fixed clamp seat 61 move to the front end of the strap 9, and the lifting plate 63 is driven by the clamping cylinder 65 to press the movable clamp 62 downward, forming a closed state with the fixed clamp seat 61 to clamp the front end of the strap 9. On the contrary, the lifting plate 63 drives the movable clamp 62 to rise, and forms an open state with the fixed clamp seat 61, that is, the strap 9 is released. After the strap 9 is clamped, the strap 9 is pulled, squeezing and moving at the same time, until the strap 9 is completely pulled out from between the upper roller 521 and the lower roller 522 and then moved to the unloading position, the clamping claw mechanism 3 on the second linear module 72 extends into the unloading position to take out the strap 9, and then the strap 9 that has completed the rolling process is released, and the strap 9 falls into the collection box 8.

[0035] The feeding mechanism includes a feeding machine 2, in which a feeding tray bin 21 and a discharging tray bin 22 are provided. A feeding manipulator 23 is provided on the feeding machine 2, and the strap 9 on the tray is fed into the pressing mechanism 4 by the feeding manipulator 23. During the feeding process, the feeding manipulator 23 and the clamping mechanism 3 on the first linear module 71 stagger their movements to avoid interference.

[0036] List the specific workflow:

[0037] S1 loading:

[0038] The strap 9 placed in the loading tray bin 21 is accurately fed into the pressing mechanism 4 by the loading machine 2, specifically the loading manipulator 23. The unloading tray bin 22 is used to store the processed strap 9, which is convenient for continuous loading and unloading operations.

[0039] S2 pressure processing:

[0040] After the strap 9 is fed into the pressing mechanism 4, the limit motor 410 first drives the screw rod 49 and the limit plate 48 to ensure that the strap 9 maintains the correct position during the pressing process to prevent displacement or deviation. The pressing cylinder 42 starts to work and drives the pressing plate 44 to press the strap 9. The pressing plate 44 is connected to the push plate 43 through the spring 46 and the guide column 45 to ensure that there is a buffering effect during the pressing process to prevent the strap 9 from being crushed. The pressing mechanism 4 has two sets of pressing plates 44, which can press two parts of the strap 9 at the same time to improve processing efficiency.

[0041] S3 is transferred to rolling mechanism 5:

[0042] After the pressing is completed, the clamping mechanism 3 is driven by the first linear module 71 and moves in a straight line. When the clamping mechanism 3 moves to one side of the pressing mechanism 4, the front and rear driving mechanisms move forward and move the movable clamping jaw 37 and the fixed clamping jaw 38 through the slot 412 and move to both sides of the strap 9. At the same time, the variable pitch slide plate 35 is driven horizontally by the variable pitch cylinder 34 to adjust the distance between the movable clamping jaw 37 and the fixed clamping jaw 38 to adapt to the strap 9 whose length changes after the pressing, and then the strap 9 is clamped by the movable clamping jaw 37 and the fixed clamping jaw 38 at the same time. Then the front and rear driving mechanisms move backward and bring the strap 9 out of the slot 412, and then the first linear module 71 drives the clamping mechanism 3 to move in a straight line to transfer the strap 9 to the rolling mechanism 5.

[0043] S4 strap 9 is pushed into the rolling mechanism 5:

[0044] A watchband pushing mechanism and a feed plate 53 are provided on one side of the rolling mechanism 5. When the clamp mechanism 3 places the watchband 9 on the feed plate 53, the pushing cylinder 59 starts to work, driving the pushing plate 58 to push the watchband 9 between the roller group 52.

[0045] S5 rolling treatment:

[0046] After the strap 9 enters the roller set 52, it is rolled through the gap between the upper roller 521 and the lower roller 522. As the strap 9 moves, the paper tape 10 also moves, ensuring that the surface of the strap 9 is always protected during the rolling process.

[0047] S6 strap 9 pulling out and preparing for cutting:

[0048] After rolling is completed, the movable clamp 62 is driven downward by the clamping cylinder 65 to form a closed state with the fixed clamp seat 61 to clamp the front end of the strap 9. Then, the movable clamp 62 and the fixed clamp seat 61 move together to pull the strap 9 out of the roller group 52 and move to the unloading position.

[0049] S7 Collection Strap 9:

[0050] The clamp mechanism 3 on the second linear module 72 extends into the unloading position, and clamps the watch strap 9 that has completed the rolling process through the movable clamp 37 and the fixed clamp 38. Subsequently, the clamp mechanism 3 releases the watch strap 9, causing it to fall into the collection box 8.

[0051] Among them, the above steps S1-S7 can be classified as a "pat and roll" processing process, but in our actual process, the corresponding watch strap 9 also needs to go through a second "pat and roll" processing process (consistent with the above steps S1-S7), and then go through the third "pat and roll" processing process, the fourth "pat and roll" processing process, the fifth "pat and roll" processing process, and then go through the sixth "pat and pat" processing process. In the sixth "pat and pat" processing process, it is actually equivalent to setting up two sets of pat and press mechanisms 4, and then one set of pat and press mechanisms 4 implements the corresponding steps S1-S2, and then is transferred to another set of pat and press mechanisms 4 through a conventional manipulator to implement the "pat" processing process (that is, repeat steps S1-S2 again). Therefore, the complete expression processing process is "pat", "roll", "pat", "roll", "pat", "roll", "pat", "roll", "pat", "roll", "pat", "pat", "pat".

[0052] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
