[0044] like Figure 1 As shown, in one embodiment, a button feeding device 10 is provided, and the button feeding device 10 includes a clamping component 1, a pushing component 2, a limiting component 3, a base 4 and a driving component 5. The clamping component 1 is used to clamp the button 20; the pushing component 2 is used to push out the button 20 clamped by the clamping component 1; the limiting component 3 is used to limit the movement of the pushing component 2; the clamping component 1 and the pushing component 2 are respectively arranged on the base 4; the driving component 5 is used to drive the base 4 to move; when the button needs to be fed, the driving component 5 drives the base 4 to move in the direction of feeding the button, so that the base 4 drives the clamping component 1 to move in the direction of feeding the button. The push-out assembly 1 and the push-out assembly 2 move. When the button 20 reaches the specified position, the limit assembly 3 can limit the push-out assembly 2 from moving in the resetting direction. The driving member 5 drives the base 4 to move in the resetting direction, so that the base 4 drives the clamping assembly 1 to move, so that the push-out assembly 2 can push out the button 20 clamped by the clamping assembly 1. After the button 20 is pushed out, the clamping assembly 1 can release the restriction of the limit assembly 3 on the push-out assembly 2, so that the base 4 drives the clamping assembly 1 and the push-out assembly 2 to move in the resetting direction, wherein the button feeding direction and the resetting direction are opposite.

[0045] When the button 20 reaches the designated position, since the push-out assembly 2 is limited by the limit assembly 3, when the driving member 5 drives the base 4 to move in the reset direction, the push-out assembly 2 is stationary, but the clamping assembly 1 is moving. During the movement of the clamping assembly 1, the button 20 is blocked by the push-out assembly 2 and detaches from the clamping assembly 1, which is equivalent to that when the clamping assembly 1 is moving, the button 20 is immobile under the action of the push-out assembly 2, so that the button 20 can accurately stay at the designated position of the sewing area, thereby improving the sewing quality of the button 20. After the button 20 is pushed out, the limit assembly 3 on the push-out assembly 2 is released by the clamping assembly 1, so that the base 4 drives the clamping assembly 1 and the push-out assembly 2 to move in the reset direction, thereby completing the reset state.

[0046] The clamping assembly 1 includes a connected buckle clip 11 and a rotating member 12, wherein the buckle clip 11 is arranged on the rotating member 12, and the rotating member 12 is arranged on the base 4. The buckle clip 11 can be driven to rotate by the rotating member 12, so that the buckle clip 11 can clamp the button 20 and rotate, so that the clamping assembly 1 can meet the needs of different scenarios, thereby improving the applicability of the button delivery device 10.

[0047] The buckle clip 11 includes a first clamping portion 111 and a second clamping portion 112, which are respectively arranged on the rotating member 12, the first clamping portion 111 is provided with a first guide groove 1111, and the second clamping portion 112 is provided with a second guide groove (not shown in the figure), the first guide groove 1111 and the second guide groove cooperate with each other to clamp the button 20, and one end of the push-out assembly 2 is passed through the rotating member 12 and is located between the first clamping portion 111 and the second clamping portion 112. Through the mutual cooperation of the first guide groove 1111 and the second guide groove, the button 20 can be reliably slid between the two guide grooves, and through one end of the push-out assembly 2 is passed through the rotating member 12 and is located between the first clamping portion 111 and the second clamping portion 112, the push-out assembly 2 can reliably push out the button 20 between the two guide grooves, thereby improving the reliability of the button insertion and button delivery of the button delivery device 10.

[0048] Specifically, one end of the ejection assembly 2 is passed through the rotating shaft 121 of the rotating member 12 .

[0049] The clamping assembly 1 further comprises a support seat 13, the support seat 13 is arranged on the base 4, and the rotating member 12 is arranged on the support seat 13. The rotating member 12 can be supported by the support seat 13, thereby improving the stability of the rotating member 12 during the rotation process.

[0050] The support seat 13 includes a first support seat 131 and a second support seat 132. The first support seat 131 and the second support seat 132 are respectively arranged on the base 4. One end of the rotating shaft 121 of the rotating member 12 is arranged on the first support seat 131, and the other end is arranged on the second support seat 132. The first support seat 131 and the second support seat 132 can support different positions of the rotating member 12, thereby further improving the stability of the rotating member 12 during rotation.

[0051] The clamping assembly 1 further includes a thrust ring 14, which is sleeved on the rotating shaft 121 of the rotating member 12. The thrust ring 14 can prevent the rotating shaft 121 of the rotating member 12 from axial displacement and radial shaking, thereby improving the stability of the rotating member 12 during rotation.

[0052] like Figure 2-4 As shown, the ejection assembly 2 includes a connected ejection member 21 and a resisting element 22, the resisting element 22 can be slidably arranged on the base 4, one end of the resisting element 22 can elastically resist against the limiting assembly 3, and the clamping assembly 1 also includes a releasing member 15, which is arranged on the base 4; when the button 20 reaches the specified position, the limiting assembly 3 can limit the movement of the resisting element 22 in the reset direction; after the button 20 is ejected, the base 4 drives the releasing member 15 to move in the reset direction, so that the releasing member 15 resists and pushes one end of the resisting element 22 to move inward, so as to release the restriction of the limiting assembly 3 on the resisting element 22. Since one end of the resisting element 22 is elastic, when the resisting element 22 moves to one side of the limiting component 3, one end of the resisting element 22 protrudes forward and resists the side wall of the limiting component 3, so that the limiting component 3 can reliably limit the movement of the resisting element 22 in the resetting direction. When the button 20 is pushed out, the base 4 drives the releasing member 15 to move in the resetting direction, so that the releasing member 15 resists and pushes one end of the resisting element 22 to move inward, so that the releasing member 15 can reliably release the restriction of the limiting component 3 on the resisting element 22, thereby improving the reliability of resetting the pushing component 2.

[0053] In this embodiment, the ejecting member 21 is a push rod.

[0054] Specifically, one end of the ejecting member 21 passes through the rotating shaft 121 of the rotating member 12 and is located between the first clamping portion 111 and the second clamping portion 112 .

[0055] The supporting element 22 includes a supporting piece 221 and a mounting seat 222. The mounting seat 222 is provided with a mounting groove 2221. One end of the supporting piece 221 can be elastically arranged in the mounting groove 2221 and the other end protrudes from the notch of the mounting groove 2221, so that the other end of the supporting piece 221 can elastically resist the limit component 3, and the mounting seat 222 can be slidably arranged on the base 4; when the button 20 reaches the specified position, one end of the supporting piece 221 protrudes forward and resists the side wall of the limit component 3, so that the limit component 3 limits the supporting piece 221 to move in the reset direction; when the button 20 is pushed out, the base 4 drives the releasing piece 15 to move in the reset direction, so that the releasing piece 15 resists and pushes the other end of the supporting piece 221 to move inward, so as to release the restriction of the limit component 3 on the supporting piece 221. By opening a mounting groove 2221 in the mounting seat 222 , the resisting member 221 can be disposed in the mounting groove 2221 , thereby improving the space utilization of the mounting seat 222 , making the structure of the resisting element 22 more compact, and reducing the volume of the resisting element 22 .

[0056] In this embodiment, the resisting member 221 is a ejector pin.

[0057] like Figure 5-6 As shown, one end of the supporting member 221 that supports the limiting assembly 3 has a guide surface 2211, which is arranged so that the releasing member 15 can support one end of the supporting member 221 through the guide surface 2211, so that one end of the supporting member 221 can reliably move inward, thereby improving the reliability of the releasing member 15 in releasing the restriction of the limiting assembly 3 on the supporting member 221.

[0058] One end of the abutting member 221 abutting against the limiting assembly 3 has a slide 2212, and the inner wall of the slide 2212 abuts against the side wall of the limiting assembly 3. Such an arrangement can increase the contact area between the abutting member 221 and the limiting assembly 3, thereby improving the reliability of the limiting assembly 3 limiting the abutting member 221.

[0059] In this embodiment, the guide surface 2211 and the slide table 2212 are arranged to face each other.

[0060] The supporting element 22 also includes a correcting piece 223, which is arranged on the mounting seat 222. The correcting piece 223 abuts the slide 2212 so that the supporting piece 221 can protrude vertically forward, so that the supporting piece 221 can reliably abut against the side wall of the limiting component 3, thereby improving the reliability of the limiting component 3 to limit the supporting piece 221.

[0061] like Figure 1-2As shown, the ejection assembly 2 further includes a slide rail 23 and a limiting member 24. The slide rail 23 is disposed on the base 4, the mounting seat 222 is slidably disposed on the slide rail 23, and the limiting member 24 is disposed at one end of the slide rail 23 to limit the moving range of the mounting seat 222. Such an arrangement enables the mounting seat 222 to reliably slide along the slide rail 23, thereby ensuring the reliability of the ejection assembly 2.

[0062] When the button 20 is pushed out, the distance between the limiting member 24 and the mounting seat 222 is equal to the length of the button 20 , so that the distance that the mounting seat 222 moves in the reset direction is equal to the length of the button 20 .

[0063] The limiting member 24 is adjustably disposed at one end of the slide rail 23 . With this arrangement, the distance between the limiting member 24 and the mounting seat 222 can be changed to adapt to the lengths of different buttons 20 , thereby improving the applicability of the button delivery device 10 .

[0064] The ejection assembly 2 further includes a sensor 25, which is disposed on the limiting member 24, and the sensor 25 is connected to the driving member 5 by signal; when the sensor 25 senses the mounting seat 222, the sensor 25 sends a signal to the driving member 5 to stop the driving member 5. When the sensor 25 can sense the mounting seat 222, it indicates that the mounting seat 222 has reached the reset position, and the sensor 25 sends a signal to the driving member 5 to stop the driving member 5 to avoid collision between the limiting member 24 and the mounting seat 222, thereby ensuring the service life of the button delivery device 10.

[0065] The ejection assembly 2 further includes a cylinder 26, which is connected to a mounting seat 222. When the button 20 held by the clamping assembly 1 is non-compliant, the mounting seat 222 is driven by the cylinder 26 to move in the button feeding direction, so that the mounting seat 222 drives the ejection member 21 to eject the button 20 held by the clamping assembly 1, thereby avoiding the use of non-compliant buttons 20.

[0066] In this embodiment, the cylinder 26 and the mounting seat 222 are connected via a connecting member 27 .

[0067] The limiting component 3 includes a support member 31 and a limiting member 32 disposed on the support member 31, and the limiting member 32 is used to limit the movement of the ejection component 2. When the button 20 is ejected, the distance between the limiting member 32 and the release member 15 is equal to the length of the button 20.

[0068] In this embodiment, the limiting member 32 is a plate-like structure. When the button 20 reaches the specified position, the supporting member 221 is located on one side of the limiting member 32. At this time, one end of the supporting member 221 protrudes forward and supports the side wall of the limiting member 32, so that the limiting member 32 can reliably limit the movement of the supporting member 221 in the reset direction.

[0069] The limiting member 32 is adjustably disposed on the supporting member 31 . With such a configuration, the distance between the limiting member 32 and the releasing member 15 can be changed to adapt to the lengths of different buttons 20 , thereby improving the applicability of the button delivery device 10 .

[0070] In this embodiment, the driving member 5 is a slide cylinder, and the base 4 is arranged on the slide of the slide cylinder.

[0071] Working principle:

[0072] like Figure 1-4 As shown, the buckle installation device pushes the button 20 into the two guide grooves of the buckle clip 11, and the pusher 21 moves in the reset direction under the push of the button 20. When the clamping assembly 1 clamps the button 20, the rotating member 12 drives the buckle clip 11 to rotate, so that the buckle clip 11 drives the button 20 to rotate, so that the buckle belt can be inserted into the button 20. When the buckle needs to be delivered, the driving member 5 drives the base 4 to move in the buckle delivery direction, and the base 4 drives the clamping assembly 1, the slide rail 23 and the limiting member 24 to move. When the limiting member 24 moves to the mounting seat 222, the limiting member 24 resists and drives the mounting seat 222 to move in the buckle delivery direction. When the button 20 reaches the specified position, the resisting member 221 is located on one side of the limiting member 32, and one end of the resisting member 221 protrudes forward and resists against the side wall of the limiting member 32, so that the limiting member 32 restricts the resisting member 221 from moving in the reset direction. At this time, the driving member 5 drives the base 4 to move in the reset direction, and the base 4 drives the clamping assembly 1, the slide rail 23 and the limiting member 24 to move. Since the ejection assembly 2 is limited by the limiting member 3, when the clamping assembly 1 moves, the ejection assembly 2 is stationary. However, during the movement of the clamping assembly 1, the button 20 is blocked by the ejection assembly 2 and detaches from the clamping assembly 1. This is equivalent to that when the clamping assembly 1 moves, the button 20 is immobile under the action of the ejection assembly 2, so that the button 20 can accurately stay at the designated position in the sewing area, thereby improving the sewing quality of the button 20. After the button 20 is pushed out, the limit of the limiting member 32 on the abutting member 221 is released by the releasing member 15, so that the base 4 drives the clamping assembly 1 and the mounting seat 222 to move in the reset direction. When the sensor 25 senses the mounting seat 222, the sensor 25 sends a signal to the driving member 5, and the driving member 5 controls the base 4 to stop moving, thereby completing the reset state.

[0073] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
