[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] It should be understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Please see Figure 1 This utility model embodiment provides a limiting mechanism 100 for limiting a flexible material 200. The limiting mechanism 100 includes two grippers 10, a carrier member 20, and a pressing member 30. The two grippers 10 are spaced apart and can move in directions toward each other or away from each other. The two grippers 10 are used to clamp both ends of the flexible material 200 and apply a pulling force to the flexible material 200. The carrier member 20 is used to support the flexible material 200. The pressing member 30 can move in directions toward or away from the carrier member 20 and is used to press the flexible material 200 onto the carrier member 20.

[0042] In this embodiment of the utility model, the two grippers 10 can clamp the two ends of the flexible material 200 and apply a pulling force to the flexible material 200, ensuring that the flexible material 200 extends and avoiding the folding of the flexible material 200 from affecting subsequent processing. The carrier 20 carries the flexible material 200 for processing, reducing the pulling force requirement for the two grippers 10 to clamp the flexible material 200. In addition, during the processing of the two ends of the flexible material 200, the crimping member 30 can also crimp the flexible material 200 onto the carrier 20, ensuring the stability of the relative positional relationship between the flexible material 200 and the carrier 20.

[0043] Specifically, the gripper 10 is used to hold the flexible material 200. The gripper 10 has many structures, including cylinders, motors, and other driving devices to grip or release the flexible material 200. This application will not elaborate on these details. It is understood that the grippers 10 can move in directions that bring them closer to or further away from each other. This can be one of two grippers 10 moving closer to or further away from the other gripper 10, or both grippers 10 moving closer to or further away from each other. This application does not impose any specific limitations.

[0044] It is understandable that there are many structures in which the grippers 10 move in directions that are close to or far apart from each other. They can be driven by a ball screw and a motor, or they can be driven by a cylinder and a slide rail. This application will not go into detail about these structures.

[0045] Understandably, the two grippers 10 respectively clamp the two ends of the flexible material 200 and tend to move in a direction that is relatively far apart, so as to apply a pulling force to the flexible material 200. The flexible material 200 stretches under the action of the pulling force, thereby facilitating the processing of the flexible material 200.

[0046] Understandably, the two grippers 10 can conveniently hold the flexible material 200 for loading and unloading. When the flexible material 200 needs to be processed, the two grippers 10 hold the flexible material 200 and place it on the carrier 20. Understandably, if the two grippers 10 alone are used to limit the flexible material 200 during processing, the two grippers 10 need to apply a pulling force sufficient to resist the weight of the flexible material 200. In addition, since the two grippers 10 are held at both ends of the flexible material 200, when the ends of the flexible material 200 need to be processed, the two grippers 10 cannot maintain the limitation of the flexible material 200. Therefore, this application also includes a support member 20 and a pressing member 30. During the processing of the flexible material 200, the support member 20 can support the flexible material 200, reducing the impact of the weight of the flexible material 200 on the extension of the gripper 10. In addition, the pressing member 30 can press the flexible material 200 onto the support member 20, ensuring that the relative positional relationship between the flexible material 200 and the support member 20 remains unchanged even when the gripper 10 is not limiting it, thereby ensuring processing quality. It is understandable that after the flexible material 200 is processed, the gripper 10 can continue to hold both ends of the processed flexible material 200 for unloading, which will not be described in detail in this application.

[0047] The support member 20 is used to support the flexible material 200. The support member 20 can be rectangular, cylindrical, or other shapes. The shape of the support member 20 can be adjusted according to the shape of the flexible material 200, and this application does not impose specific limitations. It is understood that the flexible material 200 can be placed entirely on the support member 20, or the flexible material 200 can partially extend beyond the support member 20. Whether the support member 20 fully abuts against a certain side of the flexible material 200 can be adjusted according to production and positioning requirements, and this application does not impose specific limitations.

[0048] Understandably, in one embodiment, the carrier 20 is provided with a carrier groove, the flexible material 200 is accommodated in the carrier groove, and the groove wall of the carrier groove limits the flexible material 200.

[0049] The crimping member 30 is used to crimp the flexible material 200 onto the carrier member 20. It is understood that the crimping member 30 can move in various directions towards or away from the carrier member 20. The crimping member 30 can move horizontally towards or away from the carrier member 20, vertically towards or away from the carrier member 20, or at a certain angle to the vertical. It is also understood that the movement trajectory of the crimping member 30 can be a straight line, an arc, or a spiral. The crimping member 30 only needs to be able to crimp the flexible material 200 onto the carrier member 20 and release the crimp to facilitate the loading and unloading of the flexible material 200. This application does not specifically limit the movement direction of the crimping member 30.

[0050] In one embodiment, the flexible material 200 is a watch strap. Further, the flexible material 200 is a metal watch strap.

[0051] Please see Figure 1 and Figure 2 In this embodiment of the utility model, the limiting mechanism 100 includes a tension drive member 40 and a tension guide rail 50. The two grippers 10 include tension grippers 11, which are slidably connected to the tension guide rail 50. The tension guide rail 50 is arranged along the direction in which the two grippers 10 approach or move away from each other. The tension drive member 40 drives the tension grippers 11 to move.

[0052] Thus, the tension drive 40 can drive the tension gripper 11 to slide along the guide rail, thereby enabling the tension gripper 11 to move in the direction of approaching or moving away from the other gripper 10, which facilitates the adjustment of the tension of the two grippers 10 on the flexible material 200.

[0053] Understandably, the limiting mechanism 100 may include two tension drive members 40 and two tension guide rails 50. The two grippers 10 correspond one-to-one with the two tension drive members 40 and the two tension guide rails 50, that is, the two grippers 10 can move in directions that are closer to each other or further away from each other.

[0054] Understandably, the limiting mechanism 100 may also be equipped with a force gauge 70, which is electrically connected to the force driving component 40 to detect the force of the force gripper 11 and ensure that the force applied by the force gripper 11 to the flexible material 200 is not too large or too small.

[0055] Please see Figure 1 and Figure 3 In this embodiment of the present invention, the limiting mechanism 100 further includes a fine-tuning component 60, which includes a fine-tuning guide rail 61, a fine-tuning support 63, a fine-tuning connector 65, and a fine-tuning limiting component 67. The fine-tuning guide rail 61 includes a limiting guide rail portion 611 and a rack guide rail portion 613. The fine-tuning support 63 is slidably connected to the fine-tuning guide rail 61. The fine-tuning connector 65 passes through the fine-tuning support 63 and is rotatably connected to the fine-tuning support 63. The fine-tuning connector 65 is also provided with a gear (not shown), which cooperates with the rack guide rail portion 613. The fine-tuning limiting component 67 passes through the fine-tuning support 63, is threadedly connected to the fine-tuning support 63, and abuts against the fine-tuning guide rail 61. The two grippers 10 also include fine-tuning grippers 13, which are disposed on the fine-tuning support 63.

[0056] Thus, the limiting guide rail 611 can slide and connect with the fine-tuning support 63, guiding the fine-tuning support 63 to move along the limiting guide rail 611. Tightening the fine-tuning connector 65 provided on the fine-tuning support 63 causes the gear of the fine-tuning connector 65 to rotate along the rack guide rail 613, thereby driving the fine-tuning support 63 to slide along the rack guide rail 613, adjusting the relative position relationship between the fine-tuning support 63 and the fine-tuning guide rail 61. After adjusting the fine-tuning support 63 and the fine-tuning guide rail 61 to the required relative position, tightening the fine-tuning limiting member 67 causes the fine-tuning limiting member 67 to abut against the fine-tuning guide rail 61. The friction between the fine-tuning limiting member 67 and the fine-tuning guide rail 61 restricts the movement of the fine-tuning support 63 relative to the fine-tuning guide rail 61, achieving the effect of adjusting the position of the fine-tuning gripper 13 according to the size of the flexible material 200, adapting to the clamping requirements of flexible materials 200 of different sizes, and compensating for installation errors, etc.

[0057] It is understandable that the fine-tuning limit member 67 can abut against the limit guide section 611, or the fine-tuning limit member 67 can abut against the rack guide section 613. The fine-tuning limit member 67 can limit the movement of the fine-tuning support 63 by friction. This application does not impose any specific limitations.

[0058] It is understandable that the setting direction of the fine-tuning guide rail 61 can be set along the direction in which the two grippers 10 approach or move away from each other, or the setting direction of the fine-tuning guide rail 61 can be set along the direction perpendicular to the direction in which the two grippers 10 approach or move away from each other, or the setting direction of the fine-tuning guide rail 61 can be set along a direction at a certain angle to the direction in which the two grippers 10 approach or move away from each other. This application will not elaborate on these specific details.

[0059] For further details, please refer to Figure 1 and Figure 3 The fine-tuning guide rail 61 is set along the direction in which the two grippers 10 move closer or further apart from each other.

[0060] In this way, the initial distance between the two grippers 10 can be easily adjusted according to the size of the flexible material 200, so as to meet the processing and limiting requirements of flexible materials 200 of different sizes.

[0061] Please see Figure 4 and Figure 5 In this embodiment of the present invention, the pressing member 30 includes a rotating pressing drive member 31 and a pressing block 33. The rotating pressing drive member 31 drives the pressing block 33 to move vertically closer to or away from the carrier member 20, and the rotating pressing drive member 31 drives the pressing block 33 to rotate horizontally to avoid the loading and unloading of the flexible material 200.

[0062] In this way, the rotating pressing drive 31 can not only drive the pressing block 33 to press the flexible material 200 vertically, avoiding friction and scratching of the flexible material 200 when the pressing block 33 moves in the horizontal direction, but also drive the pressing block 33 to rotate in the horizontal direction, thereby avoiding the loading and unloading of the flexible material 200 and improving space utilization.

[0063] Understandably, when the crimping block 33 can only move vertically, a large clearance space is usually required to avoid loading and unloading the flexible material 200. This ensures that the distance between the crimping block 33 and the carrier 20 is sufficient to accommodate the gripper 10 and the flexible material 200 during loading and unloading. However, in this embodiment, the crimping block 33 can rotate horizontally. After rotating, the crimping block 33 can avoid loading and unloading the flexible material 200, saving clearance space and improving space utilization.

[0064] The rotating pressing drive 31 can drive the pressing block 33 to move linearly in the vertical direction, and it can also drive the pressing block 33 to rotate in the horizontal direction. It can be understood that the pressing block 33 can move linearly in the vertical direction and rotate in the horizontal direction at the same time, that is, the movement direction of the pressing block 33 can be spiral; the pressing block 33 can also first rotate in the horizontal direction and then move linearly in the vertical direction. This application does not make specific restrictions.

[0065] Please see Figure 4 and Figure 5 In this embodiment of the utility model, the limiting mechanism 100 further includes a fixed abutment member 80, which is disposed on the bearing member 20 and is used to abut against the flexible material 200.

[0066] Thus, the fixed abutment 80 can abut against the flexible material 200 located on the carrier 20, so as to limit the flexible material 200 and ensure that the flexible material 200 is in the required processing position during processing.

[0067] It is understood that the fixed abutment 80 can abut against the flexible material 200 in a direction perpendicular to the direction in which the two clamps 10 approach or move away from each other. The fixed abutment 80 can also abut against the flexible material 200 in a direction at an angle to the direction in which the two clamps 10 approach or move away from each other. The fixed abutment 80 can also abut against the flexible material 200 in a direction in which the two clamps 10 approach or move away from each other. This application does not impose any specific limitations.

[0068] Please see Figure 4 and Figure 5In this embodiment of the present invention, the limiting mechanism 100 further includes a movable abutment 91 and a movable driving member 93. The movable abutment 91 moves in a direction close to or away from the fixed abutment 80 under the drive of the movable driving member 93. The movable abutment 91 is used to abut against both sides of the flexible material 200 with the fixed abutment 80.

[0069] Thus, the movable abutment 91 abuts against one side of the flexible material 200. Driven by the movable drive member 93, the movable abutment 91 moves in the direction close to the fixed abutment 80, pushing the other side of the flexible material 200 to abut against the fixed abutment 80, thereby achieving the positioning of the flexible material 200.

[0070] It is understood that the moving drive component 93 may include drive devices such as motors and cylinders, and this application does not impose specific limitations.

[0071] For further details, please refer to Figure 4 and Figure 5 The moving direction of the movable abutment 91 is perpendicular to the moving direction of the two grippers 10.

[0072] Thus, the position of the flexible material 200 along the direction of movement of the gripper 10 can be adjusted by moving the gripper 10, and the position of the flexible material 200 perpendicular to the direction of movement of the gripper 10 can be adjusted by moving the abutment 91 and the fixed abutment 80, thereby conveniently and quickly realizing the adjustment of the flexible material 200 in both directions and ensuring that the flexible material 200 is located in the position required for processing.

[0073] Please see Figure 1 In this embodiment of the utility model, the limiting mechanism 100 also includes a waste box 95, which is located below the two grippers 10.

[0074] In this way, the two grippers 10 can easily place the waste into the waste box 95, which can collect the waste and facilitate waste storage and disposal.

[0075] Understandably, after the flexible material 200 is cut and held by the jaws 10 at both ends, the cut waste is held in the two jaws 10. Therefore, the waste box 95 can facilitate the two jaws 10 to discard the processed waste, which makes it convenient for the jaws 10 to re-clamp the two ends of the processed flexible material 200 in the future.

[0076] This utility model embodiment also provides a processing device, which includes a limiting mechanism 100. The specific structure of the limiting mechanism 100 is as described in the above embodiments. Since this processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0077] In the processing equipment of this utility model embodiment, the two grippers 10 can clamp the two ends of the flexible material 200 and apply a pulling force to the flexible material 200, ensuring that the flexible material 200 extends and avoiding the folding of the flexible material 200 from affecting subsequent processing. The carrier 20 carries the flexible material 200 for processing, reducing the pulling force requirement for the two grippers 10 to clamp the flexible material 200. In addition, during the processing of the two ends of the flexible material 200, the pressing member 30 can also press the flexible material 200 onto the carrier 20, ensuring the stability of the relative positional relationship between the flexible material 200 and the carrier 20.

[0078] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
