Description

Technical Field

[0001] The present invention relates to the technical field of buckle processing, and in particular to a self-locking mechanism for a buckle. Background Art

[0002] As a connecting device, snap fasteners are widely used in connecting pipelines, valves and other pipeline accessories on automobiles.

[0003] like Figure 1 As shown, a first pin 210 and a second pin 220 extend from each end of the buckle 200, wherein a limiting hole 230 is defined on the first pin 210, and a mounting protrusion 240 extends from the end of the second pin 220. When assembling the buckle 200, the first pin 210 and the second pin 220 of the buckle 200 need to be clamped together and the mounting protrusion 240 inserted into the limiting hole 230, thereby keeping the buckle 200 in an open state and completing the self-locking of the buckle 200. In this way, when using the buckle 200, the customer only needs to remove the mounting protrusion 240 from the limiting hole 230 to shrink and tighten the buckle 200 to the desired connection position.

[0004] Since the mounting protrusion 240 on the buckle 200 needs to be inserted into the limiting hole 230, when automated equipment is used for assembly, the mounting protrusion 240 is prone to being skewed or not inserted into the limiting hole 230, which may lead to a reduction in the quality of the buckle 200. Summary of the Invention

[0005] In view of this, the present invention provides a self-locking mechanism for a buckle, which can accurately insert the mounting protrusion on the buckle into the limiting hole, thereby realizing self-locking of the buckle, realizing automated production and improving the production quality of the buckle.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a self-locking mechanism for a buckle is provided, comprising: a feeding assembly, a guide assembly arranged at one end of the feeding assembly, a pre-lift assembly and a top-opening assembly respectively arranged on both sides of the feeding assembly, the feeding assembly comprising a support member, a loading member arranged above the support member, a limiting member arranged above the loading member and a positioning member arranged at the discharge end of the loading member, the guide assembly comprising a first slide rail, a first slider, a guide member fixed on the first slider, a second cylinder and a second telescopic shaft, the pre-lifting assembly comprising a pre-lifting block, a third cylinder and a third telescopic shaft, a limiting groove is provided on the side of the pre-lifting block near the discharge end, the top-opening assembly comprises a pushing block, a fourth cylinder and a fourth telescopic shaft, and a placement groove is provided on the side of the pushing block near the discharge end.

[0007] Furthermore, a rectangular groove is provided on the loading piece.

[0008] Furthermore, the limiting member includes a support rod and a limiting rod connected to the support rod.

[0009] Furthermore, the support rod is L-shaped, one end of the support rod is connected to the side of the loading piece, and the other end of the support rod is located directly above the rectangular groove.

[0010] Furthermore, the limiting rod is connected to the other end of the supporting rod, the limiting rod is parallel to the loading piece and the limiting rod is located directly above the rectangular slot.

[0011] Furthermore, the positioning member includes a first cylinder, a first telescopic shaft extending from a top end of the first cylinder, and a positioning block connected to the first telescopic shaft.

[0012] Furthermore, the guide member includes a guide groove provided on the guide member and placement portions located on both sides of the guide groove.

[0032] like Figure 2 As shown, this embodiment provides a self-locking mechanism 100 for a buckle, comprising: a feeding component 1, a guide component 2 arranged at one end of the feeding component 1, a pre-pushing component 3 and a pushing component 4 respectively arranged on both sides of the feeding component 1.

[0033] like Figure 3As shown, the feeding assembly 1 includes a support member 11, a feeding member 12 arranged above the support member 11, a limiting member 13 arranged above the feeding member 12, and a positioning member 14 arranged at the end of the feeding member 12. The support member 11 is suitable for placing the feeding member 12. One end of the feeding member 12 is connected to a vibration plate (not shown in the figure), which is suitable for conveying the buckle 200 to the feeding member 12. A rectangular groove 121 is provided on the feeding member 12, and the width of the rectangular groove 121 matches the diameter of the buckle 200, so that the first pin 210 and the second pin 220 on the buckle 200 are placed on the upper end surface of the feeding member 12. The limiting member 13 is arranged on the feeding member 12, and the limiting member 13 includes a support rod 131 and a limiting rod 132 connected to the support rod 131. Multiple L-shaped support rods 131 are provided, with one end of each rod connected to the side of the feeder 12, and the other end of each rod located directly above the rectangular slot 121. A limiting rod 132 is connected to the other end of each rod 131, parallel to the feeder 12, and located directly above the rectangular slot 121. When the clip 200 is placed in the rectangular slot 121, the first and second pins 210, 220 on the clip 200 are placed on either side of the upper end surface of the feeder 12. The limiting rods 132 prevent the first and second pins 210, 220 from shifting. A positioning member 14 is provided at the discharge end of the feeder 12 and includes a first cylinder 141, a first telescopic shaft 142 extending from the top of the first cylinder 141, and a positioning block 143 connected to the first telescopic shaft 142. The positioning block 143 is located directly below the discharge end of the loading piece 12, and an insertion port 122 is also provided on the loading piece 12 directly above the positioning block 143. The shape of the insertion port 122 matches the positioning block 143. When the loading piece 14 completes loading of the corresponding number of clips 200, the first cylinder 141 drives the first telescopic shaft 142 and the positioning block 143 to move upward, and inserts the positioning block 143 into the first clip 200 located at the discharge end of the loading piece 12 to prevent the clip 200 from slipping out from the discharge end of the loading piece 12.

[0034] like Figure 4As shown, the guide assembly 2 is disposed on the discharge side of the feed assembly 1. The guide assembly 2 comprises a first slide rail 21, a first slider 22 mounted on the first slide rail 21, a guide member 23 fixed to the first slider 22, a second cylinder 24, and a second telescopic shaft 25 extending from one end of the second cylinder 24. The first slide rail 21 is disposed on the discharge side of the feeder 12, and the first slide rail 21 and the feeder 12 are aligned. The first slider 22 is sleeved onto the first slide rail 21. The guide member 23 is adapted to move along the first slide rail 21 with the first slider 22. The guide member 23 comprises a guide groove 231 defined therein and placement portions 232 located on either side of the guide groove 231. The guide groove 231 is rectangular, with a sensor 26 disposed at one end. The outer surface of the placement portion 232 is inclined. The second telescopic shaft 25 is connected to the guide member 23, and the second cylinder 24 is adapted to push the guide member 23 to slide along the first slide rail 22 via the second telescopic shaft 25. When the feeding assembly discharges the material, the second cylinder 24 pushes the guide 23 and makes it close to the discharge end of the loading piece 12. At this time, the buckle 200 enters the guide groove 231 from the discharge end of the loading piece 12. When four buckles 200 are closely arranged in the guide groove 231, the sensor 26 receives a guidance completion signal.

[0035] like Figure 5 As shown, the pre-elevation assembly 3 includes a second slide rail 31, a second slider 32 disposed on the second slide rail 31, a pre-elevation block 33 fixed to the second slider 32, a third cylinder 34, and a third telescopic shaft 35 extending from one end of the third cylinder 34. The second slide rail 31 is disposed on one side of the discharge end of the loading member 12, and the second slide rail 31 is disposed perpendicular to the loading member 12. The second slider 32 is sleeved on the second slide rail 31. The lower end of the side surface of the pre-elevation block 33 near the discharge end is inclined, which mates with the inclined outer side surface of the placement portion 232 of the guide member 23. A limiting slot 331 is defined at the upper end of the side surface of the pre-elevating block 33, near the discharge end. This slot 331 engages with the first pin 210 of the clip 200, and the limiting hole 230 abuts against the exterior of the limiting slot 331. When the lower end of the pre-elevating block 33 abuts the exterior surface of the placement portion 232 of the guide member 23, the limiting hole 230 abuts against the exterior of the limiting slot 331. A third telescopic shaft 35 is connected to the pre-elevating block 33, and a third cylinder 34 is adapted to push the pre-elevating block 33 to slide on the second slide rail 31 via the third telescopic shaft 35. When the clips 200 enter the guide slot 231 from the discharge end of the loading member 12, and the four clips 200 positioned within the guide slot 231 are closely aligned, the third cylinder 34 pushes the pre-elevating block 33 against the clips 200.

The ejection assembly 4 includes a third slide rail 41, a third slider 42 arranged on the third slide rail 41, a push block 43 fixed to the third slider 42, a fourth cylinder 44, and a fourth telescopic shaft 45 extending from one end of the fourth cylinder 44. The third slide rail 41 is arranged at one end of the pre-elevation assembly 3, and the third slide rail 41 is arranged perpendicular to the loading member 12. The third slider 42 is sleeved on the third slide rail 41. The lower end of the side surface of the push block 43 near the discharge end is inclined, which cooperates with the inclined outer side surface of the placement portion 232 of the guide member 23. The upper end of the side surface of the push block 43 near the discharge end is provided with a placement groove 431. There are four placement grooves 431. The placement grooves 431 are inclined grooves that cooperate with the mounting protrusion 240 on the buckle 200 and are suitable for placing the mounting protrusion 240. The fourth telescopic shaft 45 is connected to the push block 43, and the fourth cylinder 44 is suitable for pushing the push block 43 to slide on the third slide rail 41 via the fourth telescopic shaft 45. When the clip 200 enters the guide groove 231 from the discharge end of the loading member 12, and the four clips 200 located in the guide groove 231 are closely arranged, the fourth cylinder 44 pushes the push block 43 to abut against the mounting protrusion 240 of the clip 200. Then, the second cylinder 24 pushes the guide member 23 away from the discharge end of the loading member 12. The fourth cylinder 44 pushes the push block 43 and the mounting protrusion 240 abutting on the guide groove 231 toward the pre-elevating block 33, thereby inserting the mounting protrusion 240 into the limiting hole 230, completing the self-locking of the clip 200. Then, the fourth cylinder 44 pushes the push block 43 away from the pre-elevating block 33, causing the clip 200 to fall into the discharge port below after self-locking.
