Description

Technical Field

[0001] This application relates to the field of automation, and in particular to a buckle-getting mechanism and an automatic hook and buckle assembly device. Background Technology

[0002] Hooks and buckles are widely used connecting components in bags, clothing, industrial equipment and other fields. A hook and buckle includes a buckle body, a buckle head, a torsion spring, a pin, and a buckle ring. The buckle body has a buckle opening. The buckle head is rotatably mounted on the buckle body by the pin, and the buckle head can open or close the buckle opening during rotation. The torsion spring is arranged between the buckle head and the buckle body to drive the buckle head to the closed state. The buckle ring is sleeved on the outside of the buckle body so that the buckle ring can rotate relative to the buckle body.

[0003] As a crucial component of fasteners, the degree of automation in the assembly process of buckles directly impacts the efficiency and cost of the entire production line. Traditionally, buckle assembly has been largely done manually. This method is not only inefficient but also susceptible to human error in assembly quality, making it difficult to meet the demands of large-scale, high-efficiency production in modern industry.

[0004] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

[0005] To address the aforementioned issues, this application provides a buckle-grabbing mechanism and an automatic hook-and-loop assembly device, which can position the buckle to ensure accurate buckle grabbing and provide a precise reference for subsequent assembly operations.

[0006] This application provides a buckle-obtaining mechanism for an automatic hook and snap assembly device, comprising:

[0007] A buckle gripping device includes a buckle clamping claw and a buckle positioning member. The buckle clamping claw is used to grip the buckle, and the buckle positioning member can extend into a buckle positioning hole of the buckle.

[0008] A buckle separation component configured to separate the buckle from the buckle gripping device;

[0009] When the buckle clamping claw clamps the buckle, the buckle positioning member extends into the buckle positioning hole of the buckle to position the buckle.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0015] Optionally, the buckle separating member can move relative to the buckle positioning member in a first direction, so that the buckle separating member can abut against the buckle to separate the buckle from the buckle positioning member.

[0016] Optionally, the buckle clamping claw includes two arms, which cooperate with each other to clamp the buckle;

[0017] The buckle positioning component is located between the two arms.

[0018] This application also provides an automatic hook and loop assembly device, comprising:

[0050] 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.

[0051] 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.

[0052] 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.

[0053] like Figures 1 to 12 As shown, this application provides a buckle acquisition mechanism 30 for use in a hook and buckle automatic assembly equipment 100. It includes a buckle gripping device 31 and a buckle separation component 32. The buckle gripping device 31 includes a buckle clamping claw 311 and a buckle positioning component 312. The buckle clamping claw 311 is used to grip a buckle 103, and the buckle positioning component 312 can extend into the buckle positioning hole 1031 of the buckle 103. The buckle separation component 32 is configured to separate the buckle 103 from the buckle gripping device 31. When the buckle clamping claw 311 grips the buckle 103, the buckle positioning component 312 extends into the buckle positioning hole 1031 of the buckle 103 to position the buckle 103, ensuring accurate gripping of the buckle 103 and providing an accurate reference for subsequent assembly operations.

[0054] The buckle-grabbing mechanism 30 is used to accurately grasp, position, and release the buckle 103 during the automatic assembly of the hook and buckle 101. The buckle-separating component 32 is used to reliably separate the buckle 103 from the grasping device, ensuring that the buckle 103 can be smoothly placed in the designated position and complete the assembly with the buckle body 102.

[0055] In this embodiment, as Figures 5 to 7 As shown, the structure of the buckle gripper 311 is not strictly limited, as long as the buckle gripper 311 can grasp the buckle 103; for example, the buckle gripper 311 can be a pneumatic gripper. The buckle gripper 311 includes two arms 3111, which cooperate to grip the buckle 103. The two arms 3111 are pneumatically or electrically driven to open and close, and are used to grip the side wall of the buckle 103.

[0056] In this embodiment, as Figures 5 to 7 As shown, the buckle 103 also includes a buckle positioning hole 1032 that protrudes outward; the buckle positioning hole 1032 is generally cylindrical, and the buckle positioning hole 1031 is located at the buckle positioning hole 1032 and is coaxially arranged with the buckle positioning hole 1032. The buckle 103 gripper is used to grip the outer side of the buckle positioning hole 1032; the inner wall of the arm portion 3111 is an arc-shaped surface to increase the contact area with the buckle positioning hole 1032, ensuring a secure grip on the buckle 103.

[0057] In this embodiment, as Figures 5 to 7 As shown, the structure of the buckle positioning member 312 is not strictly limited, as long as the buckle positioning member 312 can be inserted into the buckle positioning hole 1031 to position the buckle 103; for example, the buckle positioning member 312 is roughly rod-shaped.

[0058] In this embodiment, as Figures 5 to 7 As shown, the buckle positioning component 312 is located between the two arm portions 3111, ensuring that the buckle 103 can be stably and accurately positioned during clamping. The buckle positioning component 312 has a transition fit with the buckle positioning hole 1031, ensuring that the buckle positioning component 312 can smoothly extend into the buckle hole 103, while ensuring sufficient stability and accuracy.

[0059] In this embodiment, as Figures 5 to 7 As shown, the end of the buckle positioning member 312 has a buckle guide portion 313 for guiding the buckle positioning member 312 into the buckle positioning hole 1031, further improving the accuracy and efficiency of the buckle positioning member 312 entering the buckle positioning hole 1031. The buckle guide portion 313 acts as a guide, allowing the buckle positioning member 312 to enter the buckle positioning hole 1031 more easily and accurately. The buckle guide portion 313 is tapered or beveled, facilitating the smooth insertion of the buckle positioning member 312 into the buckle positioning hole 1031.

[0060] In this embodiment, as Figures 5 to 7 As shown, the buckle separation component 32 allows the buckle 103 to be smoothly released from the gripping device after being precisely positioned and moved to the designated location, facilitating subsequent assembly operations. The buckle separation component 32 also enables rapid release of the buckle 103 from the buckle gripping device 31, preventing jamming. The structure of the buckle separation component 32 is not strictly limited, as long as it can separate the buckle 103 from the buckle gripping device 31; for example, the buckle separation component 32 can be roughly block-shaped.

[0061] In this embodiment, as Figures 5 to 7 As shown, the buckle separation member 32 can abut against the buckle 103. By applying a certain force or displacement, the buckle 103 can be separated from the buckle positioning member 312, so as to facilitate the separation of the buckle 103 by the buckle separation member 32. The buckle separation member 32 partially surrounds the outer side of the buckle clamping claw 311, so that the force applied by the buckle separation member 32 to the buckle body 102 is more balanced. The bottom of the buckle separation member 32 is provided with an abutment surface to abut against the buckle 103.

[0062] In this embodiment, as Figures 5 to 7As shown, the buckle positioning member 312 is movable relative to the buckle separating member 32 along a first direction, allowing the buckle positioning member 312 to extend into or disengage from the buckle positioning hole 1031. When the buckle positioning member 312 moves along the first direction, the buckle separating member 32 restricts the buckle 103 from moving with the buckle positioning member 312, ensuring stable separation of the buckle positioning member 312 from the buckle positioning hole 1031. The buckle acquiring mechanism 30 may be equipped with a drive cylinder, which can drive the buckle positioning member 312 to move along the first direction.

[0063] Of course, in other embodiments, such as Figures 5 to 7 As shown, the buckle separating member 32 can move relative to the buckle positioning member 312 along a first direction, so that the buckle separating member 32 can abut against the buckle 103 to separate the buckle 103 from the buckle 103 positioning member. When the buckle separating member 32 moves along the first direction, it can push the buckle 103 to move along the first direction until the buckle 103 separates from the buckle positioning member 312, thus ensuring the stable separation of the buckle positioning member 312 from the buckle positioning hole 1031. The buckle acquiring mechanism 30 may be equipped with a driving cylinder, which can drive the buckle separating member 32 to move along the first direction.

[0064] In this embodiment, as Figures 5 to 7 As shown, the buckle acquisition mechanism 30 also includes a buckle placement device 33, which includes a buckle vibratory feeder 331 and a buckle conveyor line 332. The buckle vibratory feeder 331 conveys the buckles 103 to the buckle conveyor line 332. The buckle gripping device 31 is used to place the buckles 103 conveyed by the buckle conveyor line 332 onto the buckle pushing member 122 of the clamping fixture 12, so as to achieve the effect of automatically transferring the buckles 103 to the clamping fixture 12. Both the buckle vibratory feeder 331 and the buckle conveyor line 332 can adopt existing technologies, which will not be further described here.

[0065] In this embodiment, as Figures 5 to 7 As shown, in the initial state, the buckle gripping claw 311 is open, and the buckle positioning member 312 is located at the expected position of the buckle positioning hole 1031. When the buckle 103 conveying device moves the buckle 103 to the vicinity of the buckle gripping claw 311, the buckle gripping claw 311 closes, and at the same time, the buckle positioning member 312 extends into the buckle positioning hole 1031, achieving precise gripping and positioning of the buckle 103. Subsequently, the entire buckle gripping device 31 carries the buckle 103 to the target position of the gripping fixture 12. When it is necessary to release the buckle 103, the buckle separating member 32 moves along the first direction, abuts against and pushes the buckle 103, causing it to separate from the buckle positioning member 312, and the buckle gripping claw 311 opens, completing the release of the buckle 103.

[0066] like Figures 1 to 12 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-head acquisition mechanism 30. 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-head acquisition mechanism 30 is the snap-head acquisition mechanism 30 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.

[0067] In this embodiment, as Figure 1 , Figure 2 and Figure 4 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, the hook-and-loop mechanism 30, and other similar structures, which 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.

[0068] In this embodiment, as Figures 1 to 4 As shown, the turntable 11 can drive the clamping fixture 12 to rotate to the buckle-collecting mechanism 30, so that the buckle-collecting mechanism 30 places the buckle 103 on the clamping fixture 12. The rotation of the turntable 11 can realize assembly line operation and improve assembly efficiency. When the hook and buckle automatic assembly equipment 100 is in working state, the turntable 11 rotates around the vertical axis. The hook and buckle automatic assembly equipment 100 also includes a motor 111 for driving the turntable 11. Multiple clamping fixtures 12 are provided on the turntable 11; the multiple clamping fixtures 12 are arranged at intervals around the circumference of the turntable 11. Among them, the first direction is parallel to the fixed axis of the turntable 11.

[0069] 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.

[0070] In this embodiment, as Figures 8 to 12As shown, the clamping fixture 12 includes a base 121, a buckle pushing member 122, and a buckle limiting member 123. The base 121 is fixed to the turntable 11. 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 can limit the buckle pushing member 122 to the first position or the second position. The hook and buckle automatic assembly equipment 100 also includes a buckle driving device 34. The buckle driving device 34 is used to drive the buckle pushing member 122. When the buckle pushing member 122 is in the first position, the buckle acquiring mechanism 30 moves the buckle 103 to the base 121 or the buckle pushing member 122. Then, the buckle driving device 34 pushes 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.

[0071] In this embodiment, as Figures 10 to 11 As shown, the base 121 can be fixed to the turntable 11 by welding or bolts. The shape of the base 121 is not strictly limited; for example, the shape of the base 121 is generally a block structure.

[0072] In this embodiment, as Figures 10 to 11 As 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 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.

[0073] In this embodiment, as Figures 10 to 11 As shown, the buckle pushing member 122 has a buckle positioning part 1221 for positioning the buckle 103. When the buckle acquiring mechanism 30 places the buckle 103 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.

[0074] In this embodiment, as Figures 10 to 11As 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, and the buckle limiting member 123 can slide along the second sliding groove to limit the movement path of the buckle limiting member 123.

[0075] In this embodiment, as Figures 10 to 11 As shown, the buckle limiting member 123 is movably connected 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 a first position or a second position. Driven by the buckle elastic member 124, the buckle limiting member 123 abuts against the buckle pushing member 122, thereby limiting the buckle pushing member 122 to the first and second positions, ensuring the stability and accuracy of the buckle 103 during the pushing process, and preventing 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, thus limiting the buckle pushing member 122 to the first and second positions. 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.

[0076] In this embodiment, as Figures 10 to 11 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. Both the movement paths of the buckle limiting member 123 and the buckle pushing member 122 are perpendicular to the fixed axis of the turntable 11.

[0077] In this embodiment, as Figures 10 to 11As 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.

[0078] In this embodiment, as Figures 10 to 11 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.

[0079] Specifically, such as Figures 10 to 11 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.

[0080] In this embodiment, as Figures 8 to 12 As shown, the buckle driving device 34 includes a buckle driving member 341 and a buckle output member 342. The buckle driving member 341 is configured to drive the buckle pushing member 122 to move to a first position or a second position; the buckle output member 342 is configured to drive the buckle driving member 341 to move.

[0081] In this embodiment, as Figures 8 to 12As shown, in order for the buckle drive device 34 to drive the buckle push member 122 to switch between the first position and the second position, there are two buckle drive members 341 and two buckle output members 342. The two buckle output members 342 drive the corresponding buckle drive members 341 respectively.

[0082] Specifically, 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.

[0083] In this embodiment, as Figures 8 to 12 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.

[0084] In this embodiment, as Figures 8 to 12 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.

[0085] In this embodiment, as Figures 8 to 12As 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.

[0086] During the process of the turntable 11 moving the clamping fixture 12 to the position corresponding to the buckle acquisition mechanism 30, the buckle linkage part 1222 will press against the pushing part 3414. The pushing part 3414 will swing in a way that compresses the elastic member 3415 so that the pushing part 3414 is in the avoidance position until the clamping fixture 12 moves to the position corresponding to the buckle acquisition mechanism 30. The pushing part 3414 is in the driving position under the reset drive of the elastic member 3415. After the buckle 103 is placed on the buckle pushing member 122, the pushing part 3414 pushes the buckle linkage part 1222 so that the buckle pushing member 122 can be driven to move from the first position to the second position.

[0087] In this embodiment, as Figures 8 to 12 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.

[0088] In this embodiment, as Figures 8 to 12 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.

[0089] In this embodiment, as Figures 8 to 12 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.
