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.

[0069] 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.

[0070] like Figures 1 to 25 As shown, this application provides an automatic snap-fit ​​assembly machine 100, including a body 20, a snap-fit ​​acquisition mechanism 40, a snap-fit ​​acquisition mechanism 60, a spring snap-fit ​​acquisition mechanism 50, a face snap-fit ​​acquisition mechanism 70, and a clamp 30. The clamp 30 includes a base 31, a fixing member 32, and a driving member 33. The base 31 is used to support the snap-fit ​​11. The fixing member 32 is movably coupled to the base 31 and has a first position and a second position. In the first position, the fixing member 32 can restrict the snap-fit ​​11 from disengaging from the base 31. In the second position, the fixing member 32 can allow the snap-fit ​​11 to disengage from or be placed on the base 31. The driving member 33 is movably coupled to the base 31 so as to drive the fixing member 32 to move from the first position to the second position in a first direction. The driving member 33 is configured to respond to the snap-fit ​​acquisition mechanism 40 to drive the fixing member 32 to move from the first position to the second position in a first direction so that the snap-fit ​​acquisition mechanism 40 places the snap-fit ​​11 on the base 31.

[0071] The buckle-mounting mechanism 40 places the buckle-mounting 11 on the base 31; the plate buckle-mounting mechanism 60 places the plate buckle 12 on the base 31; the spring clip-mounting mechanism 50 places the spring clip 13 on the base 31; and the face buckle-mounting mechanism 70 places the face buckle 14 on the base 31. Finally, the buckle-mounting 11, plate buckle 12, spring clip 13, and face buckle 14 are assembled to form a snap fastener 10, enabling the snap fastener automatic assembly machine 100 to automatically assemble the snap fastener 10, thereby improving the assembly efficiency of the snap fastener 10. When the buckle-mounting mechanism 40 places the buckle-mounting 11 on the clamp 30, the driving member 33 responds to the buckle-mounting mechanism 40 to drive the fixing member 32 to move to a second position, allowing the buckle-mounting mechanism 40 to place the buckle-mounting 11 on the base 31; when the buckle-mounting 11 is placed on the base 31 again, the fixing member 32 moves to a first position to prevent the buckle-mounting 11 from detaching from the base 31. The drive member 33 responds to the buckle acquisition mechanism 40 to ensure that the drive member 33 will drive the fixing member 32 when the buckle 11 is placed on the buckle 11, which facilitates the use of the clamp 30 and further improves the assembly efficiency of the buckle 10 by the buckle automatic assembly machine 100.

[0072] The specific structure of the snap fastener 10; referring to one embodiment, such as Figures 3 to 4As shown, the buckle 10 is a flat buckle or a square buckle; the structure of the buckle 10 can refer to existing technology. The buckle 10 can be applied to packaging boxes or gift boxes; when the lid of the packaging box or gift box is closed on the box body, the buckle 10 can connect and fix the lid to the box body. For example, the buckle 10 includes a bottom buckle and a plate buckle 12, the plate buckle 12 is rotatably installed on the bottom buckle, and the plate buckle 12 has a buckle hole 121; the bottom buckle can be fixed to the lid by welding or screws, etc., and the buckle hole 121 on the plate buckle 12 can engage with the buckle tongue on the box body to connect the lid body and the box body.

[0073] Specifically, the bottom buckle includes a buckle base 11 and a top buckle 14; the top buckle 14 is fixed to the buckle base 11, forming a cavity between them; the plate buckle 12 includes a rotating part 122, which is rod-shaped and located within the cavity; a spring piece 13 is located within the cavity and presses against the rotating part 122 and the buckle base 11 or the top buckle 14 to provide damping for the rotation of the plate buckle 12. The buckle base 11 has multiple lugs 111, and the top buckle 14 has through holes 141 through which the lugs 111 pass. When the top buckle 14 is placed on the buckle base 11, the lugs 111 pass through the through holes 141, and then the lugs 111 are riveted to fix the buckle base 11 and the top buckle 14. The number of lugs 111 and through holes 141 is determined according to actual needs; for example, there are three lugs 111 and three through holes 141.

[0074] The specific configuration of the body 20; refer to one embodiment, such as Figures 1 to 2 As shown, the shape of the body 20 is not strictly limited; the body 20 only needs to be able to support components such as the clamp 30 and the buckle acquisition mechanism 40; the specifics of the body 20 will not be further elaborated here. For example, the body 20 may have a frame structure.

[0075] The specific arrangement of the base 31; referring to one embodiment, such as Figures 5 to 9 As shown, the shape of the base 31 is not strictly limited; the base 31 only needs to be able to support components such as the fixing member 32 and the driving member 33; for example, the base 31 has a block structure. The base 31 has a placement groove 311 for placing the buckle 11, so that the buckle 11 can be placed on the base 31. The placement groove 311 has an opening for the buckle 11 to enter and exit, and the opening is located at the top of the base 31. In the first position, part of the fixing member 32 is located at the opening of the placement groove 311, so as to prevent the buckle 11 from leaving the placement groove 311; in the second position, the fixing member 32 avoids the opening, so that the buckle 11 can enter and exit the placement groove 311.

[0076] In this embodiment, as Figures 5 to 9As shown, the base 31 has a first slide groove 312 for the fixing member 32 to slide; the first slide groove 312 can restrict the movement path of the fixing member 32. The first slide groove 312 extends through the entire base 31 along a first direction and is located below the placement groove 311. The base 31 has a second slide groove 313 for the driving member 33 to slide; the second slide groove 313 can restrict the movement path of the driving member 33. The second slide groove 313 extends through the entire base 31 along a second direction and is located on one side of the placement groove 311. The first direction and the second direction are perpendicular to each other; the first slide groove 312 and the second slide groove 313 are interconnected at their intersection.

[0077] The specific arrangement of the fastener 32; refer to one embodiment, such as Figures 5 to 9 As shown, the fixing member 32 includes a sliding part 321, a supporting part 322, and a locking tongue 323. The sliding part 321 can slide along the first sliding groove 312. The locking tongue 323 is fixed to the sliding part 321 via the supporting part 322. When the fixing member 32 is in the first position, at least a portion of the structure of the locking tongue 323 can be located at the opening of the placement groove 311 to restrict the buckle 11 in the placement groove 311. When the fixing member 32 is in the second position, the locking tongue 323 avoids the opening of the placement groove 311. One end of the supporting part 322 is fixedly connected to the middle position of the sliding part 321, and the other end is fixedly connected to the locking tongue 323. The base 31 has a clearance space 314 that avoids the supporting part 322. The clearance space 314 communicates with the first sliding groove 312, and the clearance space 314 allows the locking tongue 323 to be located outside the base 31.

[0078] The sliding part 321 is generally rod-shaped; the supporting part 322 is generally rod-shaped, one end of the supporting part 322 is fixedly connected to the sliding part 321 by welding or bolts, and the other end is fixedly connected to the locking tongue 323 by welding or bolts; the locking tongue 323 is generally plate-shaped, one side of the locking tongue 323 can cooperate with the buckle 11 to prevent the buckle 11 from disengaging from the base 31; the locking tongue 323 is fixed to the sliding part 321 by welding or bolts.

[0079] The specific configuration of the driving component 33; refer to one embodiment, such as Figures 5 to 9 As shown, the driving member 33 is generally rod-shaped; under the constraint of the second slide groove 313, the driving member 33 moves along the second direction. The driving member 33 can abut against the fixing member 32, so that the driving member 33 can abut against the fixing member 32 to move along the first direction; the driving member 33 can drive the fixing member 32 without other linkage structures, thereby reducing the number of parts in the clamp 30 and making the structure of the clamp 30 more compact.

[0080] The driving member 33 includes a driving part 331, which can abut against the fixing member 32 to move. The driving part 331 is a driving surface; the driving surface is inclined; when the driving member 33 moves in the second direction, the position of the driving surface in contact with the fixing member 32 changes, so that the position of the fixing member 32 in the first direction can be changed. The sliding part 321 has a clearance hole for the driving member 33 to pass through, so that the structure of the clamp 30 can be made more compact.

[0081] In this embodiment, as Figures 5 to 9 As shown, the clamp 30 also includes a limiting device 34, which limits the extreme positions of the fixing member 32 to determine the first position and the second position, thereby ensuring that the fixing member 32 stops moving when it reaches the first position and the second position. Specifically, the limiting device 34 includes a first limiting part 341 and a second limiting part 342; the first limiting part 341 is connected to the fixing member 32 and is located on the outside of the base 31. When the first limiting part 341 abuts against the base 31, the fixing member 32 is positioned in the first position; the second limiting part 342 is the side wall of the clearance space 314. The support part 322 and the second limiting part 342 enable the fixing member 32 to be positioned in the second position.

[0082] In order to enable the fastener 32 to be in the first position; referring to one embodiment, such as Figures 5 to 9 As shown, the clamp 30 also includes an elastic member 35, which drives the fixing member 32 to a first position; the elastic member 35 enables the fixing member 32 to remain in the first position. The fixing member 32 has a mounting portion 324 located outside the base 31 and fixedly connected to the sliding portion 321 by bolts, snap-fit, or welding; one end of the elastic member 35 presses against the mounting portion 324, and the other end presses against the base 31. The mounting portion 324 and the second limiting portion 342 are located at opposite ends of the sliding portion 321. Preferably, the elastic member 35 is a spring.

[0083] In this embodiment, as Figures 10 to 13 As shown, the latching mechanism 40 can abut against the driving member 33 to move in a second direction, so that the driving member 33 drives the fixing member 32 to move in a first direction. The latching mechanism 40 abuts against the driving member 33 to reduce the number of connecting components between them, thereby reducing the number of parts in the automatic snap-fit ​​assembly machine 100 and making its structure more compact. A portion of the driving member 33 is located on the outside of the base 31 to facilitate the latching mechanism 40 abutting against the driving member 33.

The abutment 42 can abut against the stepped surface 332 to drive the driving member 33. The buckle acquisition mechanism 40 also includes a buckle vibrating plate 43 and a buckle conveyor line 44. The buckle vibrating plate 43 conveys the buckle 11 through the buckle conveyor line 44. The buckle gripper 41 grips the buckle 11 on the buckle conveyor line 44 and places the gripped buckle 11 onto the fixture 30, enabling automatic feeding of the buckle 11 and improving the assembly efficiency of the buckle 10. The buckle vibrating plate 43, the buckle conveyor line 44, and the buckle gripper 41 can all adopt existing technologies, which will not be further described here.

[0085] In this embodiment, as Figures 10 to 13 As shown, the latching jaw 41 is a pneumatic gripper. The latching jaw 41 includes a base 411 and two jaws 412, which cooperate to grip the latching seat 11. The abutment portion 42 is integrally formed with the base 31 to reduce the processing difficulty between the abutment portion 42 and the base 31, and to strengthen the structural strength of the abutment portion 42 and the base 31. Of course, in other embodiments, the abutment portion 42 and the base 31 are separate components, and are fixed together by bolts or welding.
