As a preferred implementation of this embodiment, referring to fig. 1, the guide rail 30 includes an integrally formed feeding straight rail 31 and a feeding curved rail 32, wherein the feeding straight rail 31 extends linearly, one end is connected to the vibration plate 120, the feeding curved rail 32 extends in a curved shape, and one end is connected to the stock cavity 421.

Here, the feeding straight rail 31 extending in a straight line firstly conveys the spring a outputted from the vibration plate 120 in a straight line, and the feeding bent rail 32 extending in a bent shape inputs the spring a into the stock cavity 421 of the stock block from the top down.

Referring to fig. 9, it can be seen that in this embodiment, the stock block includes a stock main block 42 and two stock sub-blocks 43 respectively disposed on the left and right sides of the stock main block 42, the stock sub-blocks 43 are detachably mounted on the stock main block 42 through bolts 44, and mounting holes 431 for mounting optical fiber sensors are disposed on the two stock sub-blocks 43, and the two optical fiber sensors are respectively disposed on the left and right sides of the stock cavity 421.

Note that, in this embodiment, the two optical fiber sensors are opposite-emitting optical fiber sensors, and when the optical fiber sensors sense that the feeding spring a is not successfully fed into the feeding cavity 421, the optical fiber sensors transmit data to plc, and then alarm, so that an operator can manually remove the obstacle at this time. Here, the stock material dividing block 43 is detachably provided, so that an operator can conveniently detach the stock material dividing block 43 when the obstacle is removed.

Referring to fig. 7 and 8, it can be seen that in the stock state, the spring nozzle 90 abuts against the stock dividing block 43, the side of the two stock dividing blocks 43 close to each other is respectively provided with a yielding groove 433, the two yielding grooves 433 together form a connecting channel, and the connecting channel is located between the stock preparing channel and the discharging channel 91.

Then, two preparation blocks 43 are provided with lugs 432, and one end of the guide rail 30 is clamped between the two lugs 432, wherein the lugs 432 are arranged to facilitate positioning connection between the end of the guide rail 30 and the preparation blocks. As another preferred implementation of the present embodiment, the driving source includes:

a support 51 fixedly mounted on the mount 10;

a first cylinder 52 mounted on the support 51;

a connector 53 mounted on the cylinder shaft of the first cylinder 52;

the first carriage assembly includes:

a first slider plate 54 fixed to the joint 53;

the first slider 55 is mounted below the first slider plate 54 and is slidingly connected to the slide rail 11.

Referring to fig. 5, it can be seen that the pushing device 60 further includes an engagement seat 61 mounted above the first slider plate 54, and a pushing tool 62 mounting block 62 mounted on the engagement seat 61, wherein the pushing tool 62 is mounted on the pushing tool 62 mounting block 62.

Then, the elastic push rod 71 is inserted through the first slider plate 54, and the end is locked by the locking block 72. In this embodiment, the elastic push rod 71 includes a limit rod, and a spring is sleeved on the limit rod.

When the optical fiber sensor senses that the spring a exists in the material preparing cavity 421, the first cylinder 52 works and drives the connector 53 to co-displace with the first slider plate 54 connected to the connector 53 (the arrangement of the first slider 55 can assist the displacement of the first slider plate 54 more stably along the extending direction of the slide rail 11). Since the push-broach 62 is mounted on the first slider plate 54 through the connecting seat 61 and the push-broach 62 mounting block 62, the elastic push rod 71 is fixed on the first slider plate 54 through the locking block 72, and when the first slider plate 54 is displaced along the sliding rail 11 to the side close to the stock-preparing device 40, the push-broach 62 and the elastic push rod 71 are driven to jointly displace. Note that referring to fig. 5, it can be seen that the resilient push rod 71 does not contact the second carriage assembly when the pusher 62 enters the preparation block. As the push knife 62 gradually goes deeper into the stock block, its end will abut against the spring a in the stock cavity 421 and will continue to push the spring a into the connecting channel and the discharging channel 91 in sequence. When the spring a is pushed to a predetermined position in the spring nozzle 90 by the push knife 62, the material preparation is completed, and the spring feeding mechanism is in a material preparation state.

Referring to fig. 3 and 6, it can be seen that the second carriage assembly includes:

the limit bump 86 is mounted on the mounting base 10, and has a limit end, and the push head 82 is slidably connected to the limit bump 86.

Here, the second carriage assembly and the reset aid assembly together form a second drive 80. When the spring feeding mechanism is in the stock state, the first cylinder 52 continues to drive the first slider plate 54 to move forward along the extending direction of the sliding rail 11, and at this time, the elastic push rod 71 contacts the second slider plate 84 and drives the second slider plate 84 to move forward along the extending direction of the sliding rail 11 (the arrangement of the second slider 85 can assist the second slider plate 84 to move more smoothly along the extending direction of the sliding rail 11). Note that, when the elastic push rod 71 contacts the second slider plate 84, the second air cylinder 81 is in a state of being completely deflated, the elastic push rod 71 will push the second slider plate 84, the second slider 85, the air cylinder pushing block 83, the pushing head 82 and the air cylinder shaft of the second air cylinder 81 together forward until the pushing head 82 abuts against the limiting end of the limiting bump 86, and the spring a on the spring nozzle 90 is fed onto the tool die holder 100, which is the feeding state. Then, the second air cylinder 81 is inflated, when it is confirmed that the spring a is mounted on the large and small piece assembly b on the tooling die holder 100, the first air cylinder 52 drives the elastic push rod to retract and reset, the second air cylinder 81 drives the push head to retract and reset together, and drives the air cylinder push block 83, the second slide block plate 84 and the second slide block 85 to retract and reset until the spring nozzle 90 mounted above the second slide block plate 84 is contacted with the material preparation block again, and then preparation for preparing the next spring a can be started.

The spring feeding mechanism of the high-speed clip assembling machine is only the preferred embodiment of the utility model, and is not limited to the patent scope of the utility model, and the equivalent structural changes made by the description and the drawings of the utility model or the direct/indirect application of the spring feeding mechanism in other related technical fields are included in the patent protection scope of the utility model under the inventive concept of the utility model.
