[0051] 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.

[0052] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. 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.

[0053] 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.

[0054] like Figures 1 to 11 As shown, this application provides a hook and buckle clamping fixture for an automatic hook and buckle assembly device 100, including a base 121, a buckle pushing member 122, and a buckle limiting member 123. The buckle pushing member 122 is movably coupled to the base 121 and has a first position and a second position. The buckle limiting member 123 is movably coupled to the base 121 via a buckle elastic member 124. The buckle limiting member 123 is configured to be driven by the buckle elastic member 124 to limit the buckle pushing member 122 to the first position or the second position. When the buckle pushing member 122 is in the first position, the buckle 103 is moved to the base 121 or the buckle pushing member 122. Then, the buckle pushing member 122 drives the buckle 103 until the buckle pushing member 122 moves to the second position, so that the buckle 103 is assembled onto the buckle body 102 located on the base 121, thereby achieving the effect of automatic assembly of the buckle 103.

[0055] In this embodiment, as Figure 3 , Figure 5 and Figure 6 As shown, the shape of the base 121 is not strictly limited; for example, the base 121 is generally a block structure. The base 121 has a groove for placing the buckle 102; the buckle 102 is placed in the groove.

[0056] In this embodiment, as Figures 6 to 7As shown, the structure of the buckle pushing member 122 is not strictly limited, as long as the buckle pushing member 122 can push the buckle 103 to move; for example, the buckle pushing member 122 has a block structure. When the buckle 103 is placed on the hook and buckle clamping fixture 12: the buckle 103 can be placed on the base 121 or on the buckle pushing member 122. The base 121 is provided with a first sliding groove, and the buckle pushing member 122 can slide along the first sliding groove to limit the movement path of the buckle pushing member 122.

[0057] In this embodiment, as Figures 6 to 7 As shown, the buckle pushing member 122 has a buckle positioning part 1221 for positioning the buckle 103. When the buckle 103 is placed on the buckle pushing member 122, the buckle positioning part 1221 can position the buckle 103, ensuring accurate alignment between the buckle 103 and the buckle body 102 during assembly, further improving the assembly quality and efficiency of the buckle 103. The buckle positioning part 1221 is a groove structure; a portion of the buckle 103 is located within the buckle positioning part 1221 to position the buckle 103.

[0058] In this embodiment, as Figures 6 to 7 As shown, the structure of the buckle limiting member 123 is not strictly limited, as long as the buckle limiting member 123 can limit the buckle pushing member 122 to the first position or the second position; for example, the buckle limiting member 123 is generally a block structure. The base 121 is provided with a second sliding groove, along which the buckle limiting member 123 can slide to limit its movement path.

[0059] In this embodiment, as Figures 6 to 7 As shown, the buckle limiting member 123, driven by the buckle elastic member 124, abuts against the buckle pushing member 122, thereby limiting the buckle pushing member 122 to the first and second positions. This ensures the stability and accuracy of the buckle 103 during the pushing process and prevents assembly errors caused by misoperation or external interference. The elastic force of the buckle elastic member 124 increases the friction between the buckle limiting member 123 and the buckle pushing member 122, thereby increasing the resistance of the buckle pushing member 122 during movement and thus limiting the buckle pushing member 122 to the first and second positions.

[0060] In this embodiment, as Figures 6 to 7 As shown, the movement path of the buckle limiting member 123 is approximately perpendicular to the movement path of the buckle pushing member 122. The buckle limiting member 123 is located on one side of the buckle pushing member 122; the end of the buckle limiting member 123 can abut against the side of the buckle pushing member 122.

[0061] In this embodiment, as Figures 6 to 7 As shown, of the buckle limiting member 123 and the buckle pushing member 122, one has a buckle limiting groove 1223, and the other has a buckle limiting protrusion 1231 that mates with the buckle limiting groove 1223. The buckle limiting protrusion 1231 and the buckle limiting groove 1223 ensure that the buckle pushing member 122 is stably limited to the first position and the second position, thereby improving the positioning accuracy and stability of the buckle pushing member 122, increasing assembly efficiency, and ensuring the accurate assembly position of the buckle 103. The buckle limiting groove 1223 and the buckle limiting protrusion 1231 are located at the point where the buckle limiting member 123 and the buckle pushing member 122 abut.

[0062] In this embodiment, as Figures 6 to 7 As shown, there are two buckle-limiting protrusions 1231 and one buckle-limiting groove 1223. When the buckle-pushing member 122 moves to the first position, the buckle-limiting groove 1223 engages with one of the buckle-limiting protrusions 1231. When the buckle-pushing member 122 moves to the second position, the buckle-limiting groove 1223 engages with the other buckle-limiting protrusion 1231. Alternatively, in other embodiments, there are two buckle-limiting grooves 1223 and one buckle-limiting protrusion 1231; when the buckle-pushing member 122 moves to the first position, the buckle-limiting protrusion 1231 engages with one of the buckle-limiting grooves 1223; when the buckle-pushing member 122 moves to the second position, the buckle-limiting protrusion 1231 engages with the other buckle-limiting groove 1223.

[0063] Specifically, such as Figures 6 to 7 As shown, there are two buckle-limiting protrusions 1231; along the moving path of the buckle-pushing member 122, the two buckle-limiting protrusions 1231 are spaced apart at the ends of the buckle-limiting member 123. The outer contour of the buckle-limiting protrusion 1231 is approximately arc-shaped, and the outer contour of the buckle-limiting groove 1223 is approximately the same as the outer contour of the buckle-limiting protrusion 1231. This facilitates the separation of the buckle-limiting protrusion 1231 from the buckle-limiting groove 1223.

[0064] In this embodiment, as Figures 6 to 7 As shown, the buckle elastic member 124 is a spring; one end of the spring is connected to the buckle limiting member 123, and the other end is connected to the base 121. Specifically, the spring is connected to the end of the buckle limiting member 123 that pushes the fastener away from the buckle 103.

[0065] In this embodiment, as Figures 9 to 11As shown, the hook and buckle clamping fixture 12 also includes a buckle pushing member 125, which is movably coupled to the base 121 via a buckle elastic member 126, and has a third position and a fourth position. When the buckle pushing member 125 is in the fourth position by compressing the buckle elastic member 126, the buckle 106 is moved to the base 121 or the buckle pushing member 125. Then, the buckle pushing member 125 pushes the buckle 106 under the reset drive of the buckle elastic member 126 until the buckle pushing member 125 moves to the third position, so that the buckle 106 is assembled into the buckle body 102 located on the base 121.

[0066] The retaining ring elastic member 126 provides elastic support and reset for the retaining ring pushing member 125. When the retaining ring pushing member 125 is in the fourth position, it compresses the retaining ring elastic member 126. The retaining ring elastic member 126 drives the retaining ring pushing member 125 to remain in the third position. When the retaining ring pushing member 125 is in the fourth position, it moves the retaining ring 106 to the base 121 or the retaining ring pushing member 125. Then, driven by the reset of the retaining ring elastic member 126, the retaining ring pushing member 125 pushes the retaining ring 106 until it moves to the third position, so that the retaining ring 106 is assembled on the outside of the retaining body 102 located on the base 121, thereby achieving the effect of automatic assembly of the retaining ring 106.

[0067] In this embodiment, as Figures 9 to 11 As shown, the structure of the buckle pushing member 125 is not strictly limited, as long as the buckle pushing member 125 can push the buckle 106 to move; for example, the buckle pushing member 125 has a block structure. When the buckle 106 is placed on the hook clamping fixture 12: the buckle 106 can be placed on the base 121 or on the buckle pushing member 125. The base 121 has a buckle limiting groove, and the buckle pushing member 125 can slide along the buckle limiting groove to move the buckle pushing member 125.

[0068] In this embodiment, as Figures 9 to 11 As shown, the buckle pushing member 125 has a buckle positioning unit 1251. The buckle 106 cooperates with the buckle positioning unit 1251 so that the buckle connecting hole 1061 on the buckle 106 is aligned with the buckle pivot portion 1022 of the buckle body 102. When the buckle pushing member 125 pushes the buckle 106 to move, it can move the buckle connecting hole 1061 on the buckle 106 to the buckle pivot portion 1022 of the buckle body 102, so that the buckle connecting hole 1061 on the buckle 106 is sleeved on the buckle pivot portion 1022 of the buckle body 102, thereby further improving the assembly quality and efficiency of the buckle 106.

[0069] In this embodiment, as Figures 9 to 11As shown, the buckle positioning unit 1251 includes a buckle positioning groove. A portion of the buckle 106 can be positioned within the buckle positioning groove to achieve precise positioning and prevent the buckle 106 from shifting during the pushing process. The buckle positioning unit 1251 also includes a first buckle positioning part 1252 and a second buckle positioning part 1253. The first buckle positioning part 1252 is located on the outer side of the buckle 106; the second buckle positioning part 1253 is located on the inner side of the buckle 106. The first buckle positioning part 1252 and the second buckle positioning part 1253 cooperate with each other to form the buckle positioning groove.

[0070] In this embodiment, as Figures 9 to 11 As shown, there are two first buckle positioning parts 1252, located on the outer side of the buckle 106 and on both sides of the buckle connecting hole 1061. There are also two second buckle positioning parts 1253, located on the inner side of the buckle 106 and on both sides of the buckle connecting hole 1061, so as to correspond to two opposite sides inside the buckle 106. Both the first buckle positioning parts 1252 and the second buckle positioning parts 1253 have a columnar structure.

[0071] In this embodiment, as Figures 9 to 11 As shown, the retaining ring elastic member 126 not only provides the necessary elastic support for the retaining ring pushing member 125, but also ensures its automatic reset function after operation. When the retaining ring pushing member 125 is in the fourth position, it compresses the retaining ring elastic member 126, accumulating reset energy; while the retaining ring elastic member 126 always maintains the tendency to push the retaining ring pushing member 125 to the third position. The retaining ring elastic member 126 is a spring.

[0072] like Figures 1 to 11 As shown, this application also provides an automatic hook and snap assembly device 100, including a frame 10, a turntable 11, a hook and snap clamping fixture 12, and a snap head driving device 34. The turntable 11 is configured to rotate around a fixed axis and is disposed on the frame 10; the hook and snap clamping fixture 12 is disposed on the turntable 11; the hook and snap clamping fixture 12 is the hook and snap clamping fixture 12 in the above embodiments; the snap head driving device 34 is used to drive the snap head pushing member 122 to move to a first position or a second position. 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.

[0073] In this embodiment, as Figure 1 , Figure 3As 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 hook drive device 34, 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 assembly automatic assembly equipment 100.

[0074] In this embodiment, as Figures 1 to 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 hook and snap clamping fixtures 12 are arranged circumferentially around the turntable 11.

[0075] The movement paths of the buckle limiting member 123 and the buckle pushing member 122 are both perpendicular to the fixed axis of the turntable 11; the movement path of the buckle pushing member 125 is perpendicular to the fixed axis; the movement path of the buckle pushing member 125 is perpendicular to the movement path of the buckle pushing member 122; and the movement path of the buckle pushing member 125 is parallel to the buckle limiting member 123.

[0076] In this embodiment, as Figures 1 to 3 As shown, the hook and snap clamping fixture 12 is fixed to the turntable 11. The hook and snap clamping fixture 12 is used to support and position the various components of the hook and snap 101, ensuring stability and accuracy during assembly. The number of hook and snap 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 hook and snap clamping fixtures 12 can be 8, 9, 10, 11, 12, 13, 14, 15, or 16.

[0077] In this embodiment, as Figures 4 to 8As shown, the buckle driving device 34 includes a first buckle driving component 3411, a first buckle output component 3421, a second buckle driving component 3412, and a second buckle output component 3422. The first buckle driving component 3411 is configured to drive the buckle pushing component 122 from a first position to a second position. The first buckle output component 3421 is used to drive the first buckle driving component 3411 to move. The second buckle driving component 3412 is configured to drive the buckle pushing component 122 from a second position to a first position. The second buckle output component 3422 is used to drive the second buckle driving component 3412 to move. This achieves precise control and efficient movement of the buckle pushing component 122, further improving assembly efficiency and accuracy.

[0078] In this embodiment, as Figures 4 to 8 As shown, the buckle pushing member 122 has a buckle linkage portion 1222 that cooperates with the first buckle driving member 3411 and the second buckle driving member 3412. The buckle linkage portion 1222 can extend out of the base 121 to the bottom of the turntable 11, so that the first buckle driving member 3411 and the second buckle driving member 3412 can abut against the buckle linkage portion 1222 and push the buckle linkage portion 1222.

[0079] In this embodiment, as Figures 4 to 8 As shown, the structures of the first buckle driving member 3411 and the second buckle driving member 3412 are not strictly limited, as long as they can drive the buckle pushing member 122; this will not be elaborated here. For example, both the first buckle driving member 3411 and the second buckle driving member 3412 have a block structure. The first buckle output member 3421 and the second output member can be driven by a cylinder.

[0080] In this embodiment, as Figures 4 to 8 As shown, the first buckle driving member 3411 includes a seat 3413, a pushing part 3414, and an elastic member 3415. The seat 3413 is attached to the first buckle output member 3421. The pushing part 3414 is rotatably attached to the seat 3413 about a fixed axis and has a driving position and a clearance position. The elastic member 3415 is configured to drive the pushing part 3414 to remain in the driving position. When the pushing part 3414 is in the driving position, it can abut against the first buckle driving member 3411 to push the first buckle driving member 3411. When the pushing part 3414 is in the clearance position, it can allow the first buckle driving member 3411 to pass.

[0081] During the movement of the turntable 11 in the hook clamping fixture 12, the buckle linkage 1222 presses against the pusher 3414, and the pusher 3414 swings by compressing the elastic member 3415 to keep the pusher 3414 in a clearance position until the hook clamping fixture 12 moves to the predetermined position. The pusher 3414 is then in the drive position under the reset drive of the elastic member 3415. After the buckle 103 is placed on the buckle pusher 122, the pusher 3414 pushes the buckle linkage 1222 to drive the buckle pusher 122 from the first position to the second position.

[0082] In this embodiment, as Figures 4 to 8 As shown, the seat 3413 is fixed to the piston rod of the first buckle output member 3421 by welding or bolts. The seat 3413 has a mounting groove 34131; part of the structure of the pusher 3414 is located in the mounting groove 34131 and is pivotally mounted on the seat 3413.

[0083] In this embodiment, as Figures 4 to 8 As shown, along the rotation direction of the turntable 11, the elastic element 3415 and the rotating axis of the pushing part 3414 are spaced apart. The elastic element 3415 is a spring, and the elastic element 3415 is located in the mounting groove 34131; one end of the elastic element 3415 is connected to the pushing part 3414, and the other end is connected to the seat part 3413.

[0084] In this embodiment, as Figures 4 to 8 As shown, when the pushing part 3414 is in the driving position, it is driven by the elastic member 3415 and fits against the groove wall of the mounting groove 34131, so that the movement of the pushing part 3414 can be restricted when pushing the buckle push member 122. The pushing part 3414 has an inclined guide surface 34141 to guide the buckle linkage part 1222 past the pushing part 3414.

[0085] 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.

[0086] 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.
