[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figure 1 As shown, the automatic chain linking device of this utility model includes a working platform 5 and a chain winding mechanism and a joint installation mechanism disposed on the working platform 5, wherein:

[0030] The chain winding mechanism includes a ring track 6 and a driving device for driving the chain 1 to move along the ring track 6. The ring track 6 is provided with a feed port and a docking station. One end of the chain 1 enters the ring track 6 from the feed port. The driving device drives the chain 1 to rotate around the ring track 6 once, so that both ends of the chain 1 enter the docking station.

[0031] The joint installation mechanism includes a chain feeder, a snap ring feeder, a pin feeder, and a docking device set at the docking station. The chain feeder, snap ring feeder, and pin feeder provide the docking device with chain pieces 2, snap rings 3, and pins 4, respectively. The docking device installs the chain pieces 2, snap rings 3, and pins 4 to both ends of the chain 1 to achieve a loop connection.

[0032] The chain feeding device, snap ring feeding device, and pin feeding device all include a vibratory plate 7 and a feeding pipe 8. One end of the feeding pipe 8 is connected to the outlet of the vibratory plate 7, and the other end extends to the docking device. The vibratory plate 7 includes a base and a hopper set on the base. The inner wall of the hopper is provided with a feeding track, which is spirally wrapped around the inner wall of the hopper.

[0033] like Figure 2As shown, the driving device includes a paddle 9, a mounting plate 10, and a rotating shaft 11. The rotating shaft 11 is vertically rotatably mounted on the working platform 5. The mounting plate 10 is fixedly connected to the rotating shaft 11. A telescopic member 12 is fixedly mounted on the mounting plate 10. The paddle 9 is fixedly connected to the end of the telescopic member 12. The telescopic member 12 drives the paddle 9 to translate so that the paddle 9 is inserted into the gap between the two sleeves of the chain 1. A rotating member 13 is provided on the working platform 5 to drive the rotating shaft 11 to rotate so that the paddle 9 pulls the chain 1 to rotate around the circular track 6 one revolution.

[0034] The circular track 6 is composed of several arc-shaped plates 14, which are distributed circumferentially along the axis of rotation 11. The working platform 5 is also provided with several translation drive components 19 that correspond one-to-one with the positions of each arc-shaped plate 14. Each translation drive component 19 drives the corresponding arc-shaped plate 14 to translate radially along the axis of rotation 11. Each arc-shaped plate 14 translates synchronously inward or outward to adjust the size of the circular track 6.

[0035] The docking device includes a chain link mounting section, a snap ring mounting section, and a pin mounting section, which are used to install the chain link 2, snap ring 3, and pin 4, respectively. The pin mounting section is located below the working platform 5 and is used to drive the pin 4 to rise, so that the pin 4 is inserted into the sleeves at both ends of the chain 1 from bottom to top.

[0036] like Figure 4 As shown, the pin mounting section includes a base plate 15, a clamping assembly 16 mounted on the base plate 15, and a drive mechanism for raising and lowering the base plate 15. The pin feeding device has a discharge port located on one side of the clamping assembly 16. The base plate 15 also has a pushing mechanism for pushing out the pin 4 from the discharge port. The clamping assembly 16 closes and clamps the pin 4.

The pushing mechanism includes a push block 18 and a translation drive 19 for driving the push block 18 to move.

[0037] like Figure 3 As shown, the pin installation section also includes a detection mechanism to check whether the pin 4 is qualified. A defective pin 4 has two bent pin shafts; if the defective pin 4 is lifted upwards for installation, it cannot be inserted into the sleeves at both ends of the chain 1. Therefore, before installation, it is necessary to check whether the pin 4 is qualified to ensure successful subsequent installation.

[0038] The detection mechanism includes two horizontal clamping plates 17 and a driving component for opening and closing the clamping plates 17. Both clamping plates 17 have notches on their opposite sides. When the pin 4 is clamped by the clamping assembly 16, the driving component drives the two clamping plates 17 to close. When the two pins on the pin 4 are located in the notches, and when the sides of the two clamping plates 17 can be in contact and conduct electricity, the pin 4 is detected as qualified. When the sides of the two clamping plates 17 are separated and do not conduct electricity, the pin 4 is detected as unqualified. The detection mechanism also includes a rejection device for rejecting unqualified pins 4.

[0039] The pin mounting part also includes a guide positioning mechanism, which includes two fixed pressure pins, two elastic pressure pins, and a lifting drive for driving the fixed pressure pins and elastic pressure pins to rise and fall. The two fixed pressure pins descend and press against the chain piece 2 of the chain 1 to restrict the movement of the chain 1. The two elastic pressure pins descend and insert into the sleeves at both ends of the chain 1. When the pin 4 rises, it can resist the elastic pressure pins and push the elastic pressure pins to rise.

[0040] like Figure 5 As shown, the chain link installation part includes a material drop block 20 and a push plate 21. The material drop block 20 has a channel, and the chain link feeding device has a discharge port, which is located above the channel. The chain link 2 falls from the discharge port into the channel. The push plate 21 is located in the channel. The working platform 5 is also provided with a translation drive mechanism for driving the push plate 21 to move. The push plate 21 pushes the chain link 2 to the docking position to cooperate with the pin 4 for installation.

[0041] The retaining spring installation part includes a second material drop block 22, which has a second channel. The retaining spring feeding device has a second discharge port, which is located above the second channel. The retaining spring 3 falls from the second discharge port into the second channel. The translation drive mechanism drives the push plate 21 to translate twice, so that the push plate 21 pushes the retaining spring 3 to the docking position to cooperate with the pin 4 for installation.
