[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.
[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0052] like Figures 1 to 7 As shown, this application provides a buckle fixing mechanism 80 for use in a hook and loop automatic assembly device 100, including a mounting frame, a buckle position limiting member 81, a driving device, a buckle punch 82, and a buckle output member 83. The buckle position limiting member is movably attached to the mounting frame via an elastic member and configured to limit the buckle 106 onto the clamping fixture 12. The driving device is used to drive the buckle position limiting member. The buckle punch 82 is configured to punch the buckle 106 to assemble the buckle 106 onto the buckle head 103. The buckle output member 83 is used to drive the buckle punch 82. Specifically, the driving device drives the buckle position limiting member 81 to limit the buckle 106 onto the clamping fixture 12, and then the buckle output member 83 drives the buckle punch 82 to punch the buckle 106 to assemble the buckle 106 onto the buckle body 102.
[0053] When the buckle 106 is assembled onto the buckle body 102, the buckle fixing mechanism 80 cooperates with the clamping fixture 12. Through the synergistic action of the buckle position limiting component 81, the buckle punch 82, and the buckle, the buckle 106 is assembled quickly and stably.
[0054] In this embodiment, as Figures 4 to 7 As shown, the buckle 106 is sleeved on the outside of the buckle body 102. The buckle punch 82 can punch the buckle 106 to deform the buckle 106 and restrict the buckle 106 to the buckle body 102. Specifically, the buckle 106 is sleeved on the outside of the buckle body pivot portion 1022 of the buckle body 102; the buckle position limiting member 81 restricts the buckle 106 to the clamping fixture 12, and the buckle punch 82 applies force to the outside of the buckle 106 to deform the buckle 106 and prevent it from disengaging from the buckle body pivot portion 1022.
[0055] In this embodiment, as follows Figures 4 to 7 As shown, the buckle position limiting member 81 is configured to restrict the buckle 106 on the clamping fixture 12 to prevent the buckle 106 from shifting during the fixing process. It can limit the buckle 106 by clamping, blocking, or other means to ensure that the buckle 106 maintains a stable position during the fixing operation.
[0056] In this embodiment, as Figures 4 to 7 As shown, the buckle position limiting member 81 abuts against the buckle 106 above it to limit the buckle 106. The structure of the buckle position limiting member 81 is not strictly limited, as long as the position limiting member can abut against the buckle 106; for example, the buckle position limiting member 81 is a rod-shaped structure.
[0057] In this embodiment, as Figures 4 to 7 As shown, the mounting bracket has a sliding hole, and the buckle position limiting member 81 can slide along the sliding hole, which can limit the movement path of the buckle position limiting member 81. The movement path of the buckle position limiting member 81 is parallel to the fixed axis of the turntable 11.
[0058] In this embodiment, as Figures 4 to 7 As shown, the buckle position limiting member 81 has a limiting position and a releasing position. The elastic member 84 drives the buckle 106 limiting member to remain in the releasing position. The driving device drives the buckle position limiting member 81 to the limiting position by compressing the elastic member 84.
[0059] In this embodiment, as Figures 5 to 7As shown, the elastic member 84 is a spring. The elastic member 84 presses against the retaining ring position limiting member 81 and the mounting bracket. Specifically, the retaining ring position limiting member 81 has a pressing end 811 and a fixing end 812 disposed opposite to each other. The pressing end 811 of the retaining ring position limiting member 81 can press against the retaining ring 106, and the fixing end 812 extends to the outside of the mounting bracket through a sliding hole. The elastic member 84 is sleeved on the outside of the retaining ring position limiting member 81 and presses against the mounting bracket and the fixing end 812.
[0060] In an embodiment, such as Figures 5 to 7 As shown, the driving device includes a retaining ring wedge 85 and a retaining ring driving assembly 86. The retaining ring wedge 85 is fixed to the retaining ring position limiting member 81. The retaining ring driving assembly 86 includes a retaining ring driving block 861 and a second retaining ring driving member 862. The retaining ring driving block 861 is configured to be driven by the second retaining ring driving member 862 to move and press against the retaining ring wedge 85, so as to drive the retaining ring position limiting member 81 from the release position to the limiting position, thereby improving the stability and accuracy of the retaining ring position limiting member 81 and ensuring the stability and accuracy of the retaining ring 106 during the assembly process.
[0061] In an embodiment, such as Figures 5 to 7 As shown, the retaining ring wedge 85 is fixed to the retaining ring position limiting member 81 by welding, bonding, or bolting. The retaining ring wedge 85 has a driving surface 851, which is inclined to the moving path of the retaining ring driving block 861. When the retaining ring driving block 861 abuts against the driving surface 851, it can push the retaining ring wedge 85 to move along the fixed axis of the turntable 11, thereby driving the retaining ring position limiting member 81 to move towards the retaining ring 106 until the retaining ring position limiting member 81 abuts against the retaining ring 106.
[0062] In an embodiment, such as Figures 5 to 7 As shown, the structure of the retaining ring drive block 861 is not strictly limited, as long as the retaining ring drive block 861 can drive the retaining ring wedge block 85. The second retaining ring drive component 862 can be a cylinder.
[0063] In an embodiment, such as Figures 5 to 7 As shown, the retaining ring fixing mechanism 80 also includes a guide rail 835, which is configured to guide the movement of the retaining ring drive block 861. The guide rail 835 ensures the stability and accuracy of the retaining ring drive block 861 during movement, avoiding assembly errors caused by path deviation. The guide rail 835 is a groove formed on the mounting bracket.
[0064] In an embodiment, such as Figures 5 to 7As shown, the moving path of the buckle drive block 861 is perpendicular to the moving path of the buckle position limiting member 81. This design enables the buckle position limiting member 81 to move quickly and stably to the limiting position when driven.
[0065] In this embodiment, as Figures 5 to 7 As shown, the snap ring punch 82 is a key component used to apply pressure to the snap ring 106, enabling it to be securely attached to the buckle 103. It can be designed with appropriate shape and size according to the structural characteristics of the snap ring 106 and the buckle 103, applying appropriate force to tightly connect the snap ring 106 and the buckle 103, thus completing the fixing operation of the snap ring 106. For example, the snap ring punch 82 has a rod-shaped structure; the bottom of the snap ring punch 82 is adapted to the outer side of the snap ring 106.
[0066] In this embodiment, as Figures 5 to 7 As shown, the retaining ring output component 83 is used to drive the retaining ring punch 82 to move, thereby realizing the stamping operation on the retaining ring 106. The retaining ring output component 83 can be a driving device such as a cylinder or a motor 111, which can achieve rapid and stable movement of the retaining ring punch 82 through precise control.
[0067] In this embodiment, as Figures 5 to 7 As shown, the buckle output component 83 drives the buckle punch 82 through a transmission assembly, which includes a stamping swing rod 831 that rotates around a set axis; wherein, the buckle output component 83 drives the stamping swing rod 831 to swing so as to drive the buckle punch 82 to stamp the buckle 106.
[0068] In this embodiment, as Figures 5 to 7 As shown, the middle position of the stamping swing arm 831 is pivotally mounted on the mounting bracket; the driving end of the stamping swing arm 831 is rotatably connected to the buckle output component 83, so that the buckle output component 83 can drive the stamping swing arm 831 to swing. One end of the stamping swing arm 831 engages with the buckle output component 83, and the other end engages with the buckle punch 106.
[0069] In this embodiment, as Figures 5 to 7 As shown, the transmission assembly also includes a movable seat 832 and a guide member 834. The retaining ring punch 82 is fixedly connected to the movable seat 832. The guide member 834 guides the movement path of the movable seat 832. The stamping rocker arm 831 drives the movable seat 832 to move the retaining ring punch 82, ensuring the stability and accuracy of the retaining ring punch 82 during the stamping process. The stamping rocker arm 831 abuts against the movable seat 832. A roller 8311 is provided at the end of the stamping rocker arm 831 that abuts against the movable seat 832 to reduce friction between the stamping rocker arm 831 and the movable seat 832.
[0070] In this embodiment, as Figures 5 to 7 As shown, the guide member 834 can be a guide rail, slide rail, or other structure, used to ensure the stability and accuracy of the moving seat 832 during movement. This design not only improves the driving accuracy of the buckle punch 82 but also enhances the stability and reliability of the buckle fixing mechanism 80. For example, the guide member 834 can be a guide post, and the moving seat 832 is provided with guide holes that mate with the guide posts. There are two guide posts; the moving seat 832 has two guide holes, and the two guide posts extend into their respective guide holes.
[0071] like Figures 1 to 7 As shown, this application also provides an automatic hook and snap assembly device 100, including a frame 10, a turntable 11, a clamping fixture 12, and a snap ring fixing mechanism 80. The turntable 11 is configured to rotate around a fixed axis and is disposed on the frame 10; the clamping fixture 12 is disposed on the turntable 11; the snap ring fixing mechanism 80 is the snap ring fixing mechanism 80 in the above embodiments. The automatic hook and snap assembly device 100 realizes the automated assembly of hooks and snaps 101, improving the assembly efficiency of hooks and snaps 101.
[0072] In this embodiment, as Figure 1 as well as Figure 3 As shown, the frame 10 serves as the support structure for the equipment, supporting and securing other components to ensure the stability and reliability of the entire device. The structure of the frame 10 is not strictly limited; it only needs to support the turntable 11 and the buckle fixing mechanism 80, etc., and will not be further elaborated here. For example, the frame 10 can be a frame structure. The bottom of the frame 10 is equipped with casters to facilitate the movement of the entire hook and loop automatic assembly equipment 100.
[0073] In this embodiment, as Figure 1 as well as Figure 3 As shown, the turntable 11 is configured to rotate about a fixed axis and is mounted on the frame 10; the rotation of the turntable 11 enables assembly line operation and improves assembly efficiency. In operation, the turntable 11 of the hook and snap automatic assembly equipment 100 rotates about a vertical axis. The hook and snap automatic assembly equipment 100 also includes a motor 111 for driving the turntable 11. Multiple clamping fixtures 12 are arranged circumferentially around the turntable 11.
[0074] In this embodiment, as Figures 1 to 4 As shown, the clamping fixture 12 is fixed to the turntable 11. The clamping fixture 12 is used to support and position the various components of the hook 101, ensuring stability and accuracy during assembly. The number of clamping fixtures 12 is not strictly required and can be adjusted according to actual needs, which will not be further elaborated here. For example, the number of clamping fixtures 12 can be 8, 9, 10, 11, 12, 13, 14, 15, or 16.
[0075] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.
[0076] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
