DETAILED DESCRIPTION

[0037] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0038] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0039] like Figure 1-Figure 8 As shown, an embodiment of the present invention provides a spring clip assembly device for assembling a spring clip, wherein the spring clip includes two clips 110, a torsion spring 120 and a pin 130, wherein a pin cap 131 is provided at one end of the pin 130, and a groove 132 is provided at the other end of the pin 130.

[0040] The spring clip assembly device includes a die base 200 , a torsion spring installation mechanism 300 and a pin installation mechanism 400 .

[0042] Reference Figure 4 The mold base 200 includes a base 210 and two oppositely arranged clip positioning blocks 220. The base 210 is provided with a mounting groove 211. The lower ends of the two clip positioning blocks 220 are respectively hinged in the mounting groove 211, and an installation positioning station is formed between the two clip positioning blocks 220.

[0043] The torsion spring installation mechanism 300 is used to install the torsion spring 120 between two clamping pieces 110 positioned on the installation and positioning station.

[0044] Reference Figure 2 and Figure 3 , the torsion spring installation mechanism 300 includes a torsion spring installation bracket 310, a fixing block 320, a torsion spring conveying track 330, a horizontal telescopic cylinder 340, a vertical telescopic cylinder 350, a lifting block 360 and a lifting mechanism;

[0045] The fixing block 320 is disposed above the die base 200 and fixed on the torsion spring mounting bracket 310. A connected transverse torsion spring channel 321 and a vertical torsion spring channel 322 are disposed in the fixing block 320. A first torsion spring leg avoidance groove 323 is disposed on the upper side of the transverse torsion spring channel 321. A second torsion spring leg avoidance groove 324 and a third torsion spring leg avoidance groove 325 are disposed on both sides of the vertical torsion spring channel 322.

[0046] The torsion spring conveying track 330 extends to one end of the transverse torsion spring channel 321 away from the vertical torsion spring channel 322, and a torsion spring conveying groove 331 is provided on one side of the torsion spring conveying track 330 facing the transverse torsion spring channel 321;

[0047] The transverse telescopic cylinder 340 is arranged on a side of the fixed block 320 away from the vertical torsion spring channel 322 and is installed on the torsion spring mounting bracket 310. The output end of the transverse telescopic cylinder 340 is provided with a transverse push rod 341 for pushing the torsion spring 120 at the front end of the torsion spring conveying groove 331 into the transverse torsion spring channel 321.

[0048] The vertical telescopic cylinder 350 is disposed on the upper side of the fixed block 320 and mounted on the torsion spring mounting bracket 310. The output end of the vertical telescopic cylinder 350 is provided with a vertical push rod 351 extending into the vertical torsion spring channel 322;

[0049] The lifting block 360 is disposed on a side of the fixed block 320 away from the transverse telescopic cylinder 340 . A clamping portion 361 located below the vertical torsion spring channel 322 is disposed on one side of the lower portion of the lifting block 360 . The clamping portion 361 has two clamping blocks 362 disposed opposite to each other.

[0050] The lifting mechanism is used to drive the lifting block 360 to lift vertically. Specifically, the lifting mechanism includes a lifting cylinder 370. The lifting block 360 is installed on the torsion spring mounting bracket 310 through a slide rail 363. The lifting cylinder 370 is fixed on the torsion spring mounting bracket 310. The output end of the lifting cylinder 370 is connected to the lifting block 360 to drive the lifting block 360 to lift.

[0051] When installing the torsion spring 120, the mold base 200 moves to the bottom of the clamping part 361, and the two clips 110 of the spring clamp are respectively positioned on the inner sides of the two clip positioning blocks 220, and the torsion spring 120 is transported to one end of the transverse torsion spring channel 321 through the torsion spring conveying track 330, with one leg of the torsion spring 120 facing upward and the other leg facing downward, and the transverse telescopic cylinder 340 pushes the torsion spring 120 into the transverse torsion spring channel 321 through the transverse push rod 341. Since the first torsion spring leg avoidance groove 323 is provided on the upper side of the transverse torsion spring channel 321, during the process of pushing the torsion spring 120 into the transverse torsion spring channel 321, the upper leg of the torsion spring 120 passes through the first torsion spring leg avoidance groove 323, and the lower leg is blocked, so that the torsion spring 120 automatically flips 90° to one leg facing forward and the other leg facing backward, and then moves to the vertical torsion spring channel 322 under the push of the transverse push rod 341. The upper end of the torsion spring 120 moves to the upper end of the vertical torsion spring channel 322, and the vertical telescopic cylinder 350 pushes the torsion spring 120 downward into the vertical torsion spring channel 322 through the vertical push rod 351. The two legs of the torsion spring 120 pass through the second torsion spring leg avoidance groove 324 and the third torsion spring leg avoidance groove 325 respectively, and the torsion spring 120 slides into the clamping portion 361 of the lifting block 360 through the vertical torsion spring channel 322. Then the lifting cylinder 370 drives the lifting block 360 to move downward, and the two clamping blocks 362 at the lower part respectively squeeze the two clip positioning blocks 220 on the two mold bases 200 toward the middle, so that the two clamping blocks 362 are respectively clamped on the outside of the two clip positioning blocks 220, and then the vertical telescopic cylinder 350 is controlled to drive the vertical push rod 351 to push the torsion spring 120 in the clamping portion 361 into between the two clips 110, so that the installation of the torsion spring 120 can be realized.

[0052] Reference Figure 4-Figure 7The pin installation mechanism 400 includes a pin assembly 410 and a guide pin assembly 420 respectively arranged on both sides of the mold base 200; the pin assembly 410 includes a pin fixing seat 411, a pin guide seat 412 and a pin telescopic cylinder 413, the pin guide seat 412 is fixed to the end of the pin fixing seat 411 close to the mold base 200, and a pin hole 4121 is provided in the pin guide seat 412, and the pin telescopic cylinder 413 is fixed on the pin fixing seat 411, and the output end of the pin telescopic cylinder 413 is provided with a pin rod 4131 extending into the pin hole 4121; the guide pin assembly 420 includes a guide pin fixing seat 421, a guide pin slide 422 and a guide pin guide seat 423, the guide pin slide 422 preferably adopts a slide cylinder and is installed on the guide pin fixing seat 421, and the guide pin guide seat 423 is installed on the guide pin slide 4 22, a guide hole 4231, a guide cavity 4232 and a spring mounting hole 4233 are sequentially provided on the side of the guide pin guide seat 423 close to the mold base 200, an arc groove 4234 surrounding the guide hole 4231 is provided at the end of the guide hole 4231 close to the mold base 200, a slider 424 is adapted in the guide cavity 4232, a guide pin rod 425 passing through the guide hole 4231 is fixed on one side of the slider 424, an arc-shaped protrusion 4251 capable of extending into the groove 132 of the pin 130 is provided at the end of the guide pin rod 425 close to the mold base 200, a spring 426 supported on the slider 424 is installed in the spring mounting hole 4233, and when the slider 424 is pushed to the end of the guide cavity 4232 away from the mold base 200, the arc-shaped protrusion 4251 is smoothly connected to the arc groove 4234.

[0053] Reference Figure 4 and Figure 5 In a preferred embodiment, the end of the pin guide seat 412 close to the mold base 200 is provided with a pin positioning block 4122 with two petals that can be stretched open and automatically closed, and a pin positioning hole 4123 adapted to the rod of the pin 130 is provided between the two pin positioning blocks at the front end. When the groove 132 end of the pin 130 is pushed out of the pin guide seat 412, it can be positioned through the pin positioning hole 4123 between the pin positioning blocks to ensure that the pin 130 can accurately penetrate the hole on the connecting ear of the clip 110 and the torsion spring 120. When the nail cap 131 of the pin 130 passes through the pin positioning hole 4123, the two pin positioning blocks 4122 can be stretched open, thereby ensuring that the pin rod 4131 and the nail cap 131 of the pin 130 can smoothly pass through the pin positioning hole 4123. After the spring clip is assembled, the pin rod 4131 is retracted into the pin hole 4121, and the two pin positioning blocks 4122 are automatically reset.

[0054] It should be noted that the pin positioning block 4122 can be reset by utilizing its own elasticity or by utilizing a spring reset structure, which is not specifically limited in this embodiment.

[0055] In order to facilitate the delivery of the pin 130 into the pin hole 4121, the upper part of the pin guide seat 412 is provided with a pin delivery hole 4124 which is connected with the pin hole 4121 and extends obliquely backward and upward. When the pin rod 4131 retreats to the rear of the pin delivery hole 4124, a pin 130 automatically slides into the pin hole 4121, and then the pin rod 4131 can be controlled to push out the pin 130 that has slid into the pin hole 4121. After the pinning is completed, the pin rod 4131 is retracted to the rear of the pin delivery hole 4124 again, and the next pin 130 can slide into the pin hole 4121.

[0056] When the device is used to assemble the spring clamp, first position and install the two clips 110 of the spring clamp on the mold base 200, and then install the torsion spring 120 between the two clips 110, so that the two legs of the torsion spring 120 are respectively supported on the two clips 110, and the holes in the torsion spring 120 are aligned with the holes on the connecting ears on the two clips 110, and then control the pin-penetrating telescopic cylinder 413 to drive the pin-penetrating rod 4131 to push out the pin 130 delivered to the pin-penetrating hole 4121, and at the same time, the guide pin slide 422 drives the pin-penetrating guide seat 412 to move toward one side of the mold base 200, and the pin-penetrating guide seat 412 drives the guide pin rod 425 to pass through the holes on the connecting ears on one side of the two clips 110, the holes in the torsion spring 120, and the holes on the connecting ears on the other side of the two clips 110 in sequence, until they are docked with the groove 132 end of the pin 130, and then the pin-penetrating rod 4131 pushes the pin forward while When the guide pin 424 moves to the end of the guide cavity 4232 away from the mold base 200, the arc-shaped protrusion 4251 at one end of the guide pin rod 425 is connected with the arc groove 4234 at one end of the guide pin guide seat 423, and the guide pin slide 422 continues to drive the guide seat 412 to move toward the mold base 200, and the guide pin rod 425 no longer moves, so that the groove wall at the end of the groove 132 of the pin 130 is turned outward along the arc groove 4234 at the end of the guide pin guide seat 423 (such as Figure 8 As shown), a header is formed at the penetration end of the pin 130, completing the assembly of the spring clip.

[0057] In a preferred embodiment, the device further comprises a rotating mechanism, and the guide pin guide seat 423 is rotatably mounted on the guide pin slide 422. Specifically, a support 427 is provided on the guide pin guide seat 423, and the guide pin guide seat 423 is mounted on the support 427 through a bearing 428. The rotating mechanism is used to drive the guide pin guide seat 423 to rotate. Specifically, the rotating mechanism comprises a driving motor 429 and a square shaft 4291. A square hole 4235 is provided at one end of the guide pin guide seat 423 away from the mold base 200. The driving motor 429 is close to the square hole 4235 and fixed on the guide pin fixing seat 421. One end of the square shaft 4291 is coaxially fixed to the output end of the driving motor 429, and the other end of the square shaft 4291 is plugged and adapted in the square hole 4235.

[0058] The guide pin rod 425 plays a guiding role when the pin 130 passes through the clip 110 and the torsion spring 120. When the pin is passed through, the guide pin slide 422 drives the pin passing guide seat 412 to move toward the side of the mold base 200, and at the same time, the driving motor 429 drives the guide pin guide seat 423 to rotate, so that the guide pin rod 425 rotates and advances at the same time, which can prevent the guide pin rod 425 from hitting the clip 110 or the torsion spring 120, thereby improving the success rate of the guide pin rod 425 passing through the clip 110 or the torsion spring 120. When the guide pin rod 425 is retracted or a pier head is formed at the insertion end of the pin 130, the guide pin rod 425 does not need to rotate, and the driving motor 429 does not work.

[0059] In summary, the present application can complete the forming of the through pin and the end of the pin 130 through one mechanism, thus simplifying the structure.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
