[0042] A frame 100, serving as a carrier;

[0043] A pin shaft output assembly 200, installed on the frame 100, and a first conveying channel for pin shaft conveying is provided on the pin shaft output assembly 200.

[0047] It is worth mentioning that the frame 100 is arranged in a stepped shape, including a first stepped portion 110 and a second stepped portion 120.

[0048] Preferably, the pin output assembly 200 includes a vibration plate 210 installed on the first step portion 110, and a large number of pins are placed in the vibration plate 210, wherein a pin discharge pipe 220 is provided at the edge of the vibration plate 210 to realize the output of the pins one by one, and the pin feed end 231 is located at the end of the pin discharge pipe 220 away from the vibration plate 210; the pin feed block 230 is installed on the second step portion 120 through the support 240, and the pin feed block 230 is installed on the second step portion 120 through the support 240. In the embodiment, the pin feed block 230 is provided with a first pin discharge groove 233 and a second pin discharge groove 234, the axes of the first pin discharge groove 233, the second pin discharge groove 234 and the pin discharge pipe 220 are parallel to each other, and the first pin discharge groove 233 is connected to the pin feed end 231 on the pin discharge pipe 220, and the second pin discharge groove 234 is connected to the pin discharge end 232, and the first pin discharge groove is connected to the pin feed end 231 on the pin discharge pipe 220. A pin shaft transition groove 235 is formed between 233 and the second pin shaft discharge groove 234; a first pin shaft discharge cylinder 250 is installed on the pin shaft feeding block 230, and a pin shaft discharge push block 251 is connected to the output end of the first pin shaft discharge cylinder 250, and the moving direction of the pin shaft discharge push block 251 is perpendicular to the axial direction of the first pin shaft discharge groove 233, wherein the pin shaft in the first pin shaft discharge groove 233 is discharged through the first pin shaft discharge cylinder 250. The shaft transition groove 235 enters the second pin discharge groove 234; the second pin discharge cylinder 260 is installed on the pin feeding block 230, and the output end of the second pin discharge cylinder 260 is connected to the pin discharge head 261, and the moving direction of the pin discharge head 261 coincides with the axial direction of the second pin discharge groove 234, wherein the pin in the second pin discharge groove 234 is pushed toward the pin discharge end 232 by the second pin discharge cylinder 260.

[0049] It is worth mentioning that a spring sheet 270 is provided at the pin shaft discharge end 232, and the spring sheet 270 is arranged in a T shape, wherein one end of the spring sheet 270 spans across both sides of the second pin shaft discharge groove 234 and is connected to the pin shaft feeding block 230 through fasteners, and the other end of the spring sheet 270 is located in the second pin shaft discharge groove 234.

[0050] In this embodiment, a spring sheet 270 is provided at the pin discharge end 232 to compress the pin to be assembled at the pin discharge end 232, thereby limiting the axial freedom and circumferential freedom of the pin at the pin discharge end 232, thereby improving the reliability of assembly between the pin and the retaining spring.

[0051] Preferably, the pusher assembly 300 includes a bottom plate 310 mounted on the second stepped portion 120, and a slide rail 320 is mounted on the bottom plate 310; a substrate 330, and a slider 340 is connected to the substrate 330. Among them, the slider 340 forms a sliding fit with the slide rail 320, and the snap ring output assembly 400 is mounted on the substrate 330; a pusher cylinder 350, and the output end of the pusher cylinder 350 is connected to the substrate 330. Among them, by driving the substrate 330 to move with the pusher cylinder 350, the snap ring output assembly 400 is moved closer to or away from the pin shaft discharge end 232.

[0052] Preferably, the snap ring output assembly 400 includes a positioning seat 410 arranged in a T-shaped structure, and the positioning seat 410 includes a first positioning plate 411 and a second positioning plate 412. Among them, the first positioning plate 411 is connected to the substrate 330 through a fastener, and a snap ring discharge channel is arranged on the second positioning plate 412 in the vertical direction, and the snap ring inlet end 413 and the snap ring outlet end 414 are respectively located at both ends of the snap ring discharge channel. A snap ring inlet channel is arranged on the second positioning plate 412 in the horizontal direction, and the snap ring inlet end 413 is located at the end of the snap ring inlet channel.

[0053] Further preferably, a snap ring discharge cylinder 420 is arranged on the snap ring discharge channel, and the snap ring discharge cylinder 420 is connected to the substrate 330 through a connecting column 421. Among them, the positioning seat 410 and the snap ring discharge cylinder 420 are respectively connected to the upper and lower sides of the substrate 330 in the vertical direction, and the output end of the snap ring discharge cylinder 420 is connected with a cylinder connecting block 422; a large pusher block 430, connected to the cylinder connecting block 422 and arranged in an L-shaped structure with the cylinder connecting block 422; a small pusher block 440, forming a nested sliding fit with the large pusher block 430. Among them, one end of the small pusher block 440 corresponds to the position of the snap ring inlet end 413, and the other end of the small pusher block 440 is connected to the large pusher block 430 through a first elastic member 450.

[0054] It is worth mentioning that a slot 431 is arranged on the large pusher block 430 in the vertical direction, and a limiting slot 432 communicated with the slot 431. The length direction of the slot 431, the length direction of the limiting slot 432 and the moving direction of the large pusher block 430 are parallel to each other. Among them, the small pusher block 440 is nested in the slot 431, and a limiting protrusion 441 engaged with the limiting slot 432 is arranged on the small pusher block 440.

[0055] Further preferably, the two ends of the limit groove 432 are respectively an upper limit end 4321 and a lower limit end 4322, wherein, when the retaining spring is located at the retaining spring feeding end 413, the limit protrusion 441 on the small push block 440 is clamped and abutted against the upper limit end 4321 of the limit groove 432, and the first elastic member 450 is in an extended state; when the retaining spring is located at the retaining spring discharging end 414, the limit protrusion 441 on the small push block 440 is clamped and abutted against the lower limit end 4322 of the limit groove 432, and the first elastic member 450 is in a compressed state.

[0056] Further preferably, the end of the small push block 440 that is away from the side of the limiting protrusion 441 and close to the spring feed end 413 is in an "eight"-shaped structure 442, and the middle of the "eight"-shaped structure 442 is convex, and the two sides are concave, wherein the end of the small push block 440 that is away from the side of the limiting protrusion 441 and away from the spring feed end 413 extends horizontally to form a first protrusion 443, and the second positioning plate 412 is provided with a second protrusion 415 that forms a contact abutment with the first protrusion 443, and the spring discharge channel is located on the second protrusion 415.

[0057] In this embodiment, when the retaining spring is transported from the retaining spring feeding end 413 to the retaining spring discharging end 414, the retaining spring discharging cylinder 420 first pushes the large push block 430 to move upward in the vertical direction via the cylinder connecting block 422. Since the small push block 440 is nested with the large push block 430, and the small push block 440 is engaged with the upper limit end 4321 of the limiting groove 432 under the action of the first elastic member 450, the large push block 430 drives the small push block 440 to move upward synchronously during the process of moving upward in the vertical direction. When the first protrusion 443 on the block 440 abuts against the second protrusion 415 on the second positioning plate 412, the small push block 440 will no longer follow the large push block 430 to move upward. At this time, as the large push block 430 continues to move upward, the first elastic member 450 is compressed, so that the limiting protrusion 441 on the small push block 440 continuously moves toward the lower limiting end 4322 of the limiting groove 432. When the limiting protrusion 441 on the small push block 440 is engaged with the lower limiting end 4322 of the limiting groove 432, the retaining spring just moves to the retaining spring discharge end 414, and the retaining spring and the pin shaft are located on the same horizontal plane.

[0058] It is worth mentioning that the retaining spring includes a clamping end and a closed end, wherein the retaining spring located at the retaining spring feeding end 413 has its closed end placed on the upper end of the "eight"-shaped structure 442, and its clamping end is located on both sides of the "eight"-shaped structure 442 and rests against the two ends of the groove 431.

[0059] When the first convex portion 443 on the small push block 440 comes into contact and abuts against the second convex portion 415 on the second positioning plate 412, as the large push block 430 continues to move upward, the first elastic member 450 is compressed, causing the limiting convex block 441 on the small push block 440 to gradually approach the lower limiting end 4322 of the limiting groove 432. As a result, the closed end of the snap ring is disengaged from the upper end of the "eight"-shaped structure 442, and the clamping end of the snap ring follows the large push block 430 and gradually moves toward the upper end of the "eight"-shaped structure 442. Relying on the arc surfaces on both sides of the "eight"-shaped structure 442, the clamping end of the snap ring is "spread open". When the snap ring reaches the snap ring discharge end 414, the clamping end of the snap ring reaches the maximum in the "spread open" state, thus facilitating the clamping fit between the snap ring and the pin shaft.

[0060] It can be seen from this that by providing the "eight"-shaped structure 442 on the small push block 440, not only can the precise positioning of the snap ring be achieved when it moves from the snap ring feed channel to the snap ring feed end 413, but also it can ensure that the clamping end of the snap ring is "spread open" when the snap ring and the pin shaft are clamped and assembled, thereby facilitating the clamping of the snap ring and the pin shaft and improving the working efficiency.

[0061] Further preferably, two guiding blocks 460 are provided on the second positioning plate 412, and the two guiding blocks 460 are respectively located on both sides of the second convex portion 415 and are connected to the second positioning plate 412 through fasteners. Among them, the large push block 430 is clamped between the two guiding blocks 460, and convex ribs 433 are provided at the two side edges of the large push block 430, and grooves 461 that are slidably engaged with the convex ribs 433 are provided on the guiding blocks 460.

[0062] In this embodiment, by providing the guiding blocks 460, the clamping of the large push block 430 is achieved, and in combination with the grooves 461 on the guiding blocks 460 and the convex ribs 433 on the large push block 430, the flatness of the large push block 430 when it moves under the action of the snap ring discharge cylinder 420 is ensured.

[0063] Preferably, a magazine rod 470 is provided on the snap ring feed channel, and one end of the magazine rod 470 extends into the second positioning plate 412 and corresponds to the snap ring feed end 413. The other end of the magazine rod 470 is connected to a tailstock 480. Among them, a plurality of snap rings are nested on the magazine rod 470; a spring push block 490 is nested and connected to the magazine rod 470. Among them, one side of the spring push block 490 abuts and cooperates with the snap ring nested on the magazine rod 470, and the other side of the spring push block 490 is connected to the tailstock 480 through a second elastic member 490A. As the snap rings on the magazine rod 470 are continuously output from the snap ring feed end 413, the spring push block 490 continuously approaches the positioning seat 410 under the action of the second elastic member 490A, realizing the automatic feeding of the snap rings.

[0064] Further preferably, a guide rod 490B is provided on each side of the magazine rod 470. One end of the guide rod 490B is connected to the second positioning plate 412, and the other end of the guide rod 490B is connected to the tailstock 480. An arc groove for snap-fitting with the corresponding side guide rod 490B is provided on each side of the spring push block 490. By providing the guide rod 490B, the flatness of the spring push block 490 when moving on the magazine rod 470 is ensured, avoiding deflection of the spring push block 490 during movement and improving the reliability of the snap ring output.

[0065] Preferably, a through groove 121 is provided on the second stepped portion 120. The through groove 121 is located within the assembly area 500 and penetrates through the second stepped portion 120 and the bottom plate 310. A discharge plate 130 is connected to the groove wall of the through groove 121 to enable the smooth discharge of the pin shaft and the snap ring after assembly.

[0066] Preferably, proximity switches 600 are respectively installed on the first pin shaft discharge groove 233 and the guide rod 490B.
