With continued reference to fig. 4 to 12, the circlip assembling mechanism 430 is configured to receive the circlip 10 sent from the feeding channel 210 and to clamp the circlip 10 to the shaft member 20 fixed by the shaft positioning mechanism 420. In this embodiment, the clamp spring assembling mechanism 430 includes a material receiving seat 431, a material pushing member 432, a jacking assembly 433, and a material pushing driving member 434, and both the material receiving seat 431 and the material pushing driving member 434 are supported on the supporting frame 410. The receiving seat 431 is provided with a conveying groove 4311 which is positioned on the top surface of the receiving seat and is used for moving the clamp spring 10, and the groove depth of the conveying groove 4311 is matched with the thickness of the clamp spring 10; the pushing member 432 is slidably arranged on the top surface of the material receiving seat 431, and the pushing member 432 has a fitting part 4321 located at an end thereof and used for clamping the clamp spring 10 to the clamping groove of the shaft member 20; the jacking component 433 is used for jacking the clamp spring 10 in the conveying groove 4311 into the assembling part 4321; the pushing member 432 is moved by a pushing driving member 434, which is, but not limited to, an air cylinder, and is connected and fixed to the pushing member 432. It should be noted that the conveying groove 4311 is abutted to the outlet of the feeding channel 210 for the snap spring 10 to slide in, and the direction of the snap gap 11 of the snap spring 10 in the conveying groove 4311 and the moving direction are the same as those in the feeding channel 210, when the snap spring 10 reaches the set position, the jacking component 433 jacks the snap spring 10 upwards away from the conveying groove 4311, and then the pushing driving component 434 drives the pushing member 432 to jack the snap spring 10 from back to front (wherein, the direction of the snap gap 11 is towards the front).

Referring to fig. 4 to 12, in the present embodiment, the material receiving seat 431 has a lifting hole 4312 located at the bottom surface of the conveying trough 4311, the lifting assembly 433 includes a lifting member 4331 slidably disposed in the lifting hole 4312 and a lifting driving member 4332 for lifting the lifting member 4331, the lifting driving member 4332 is supported on the supporting frame 410, and the lifting driving member 4332 is, but not limited to, an air cylinder. When the jacking member 4331 is at the lowest position, the top surface thereof is flush (i.e., on the same plane) with the bottom surface of the conveying groove 4311; when the jacking member 4331 is at the highest position, the top surface of the jacking member 4331 is flush with the top surface of the material receiving seat 431, the set position is located on the top surface of the jacking member 4331, the snap spring 10 in the conveying groove 4311 slides onto the top surface of the jacking member 4331, the jacking member 4331 is driven to ascend through the jacking driving member 4332, the snap spring 10 is jacked onto the plane where the top surface of the material receiving seat 431 is located, and then the material pushing member 432 pushes the snap spring 10. Particularly, the pushing surface (i.e., the plane where the top surface of the material receiving seat 431 is located) and the conveying surface (i.e., the plane where the bottom surface of the conveying groove 4311 is located) are staggered in height, so that the pushing member 432 does not interfere with other snap springs 10 when pushing the snap springs 10, and the assembly effect of the snap springs 10 is ensured.

Specifically, a positioning protrusion 4333 is convexly formed on the top surface of the jacking member 4331, and the positioning protrusion 4333 has a positioning wall for positioning the clamp spring 10. The latch spring 10 moved to the top surface of the jacking member 4331 stops moving after contacting the positioning wall of the positioning projection 4333, thereby positioning the position of the latch spring 10. An optical fiber sensor can be disposed on the material receiving seat 431 to detect whether the top surface of the jacking member 4331 has the clamp spring 10.

As a further optimization, the jacking member 4331 has a limiting protrusion 4334 at the bottom thereof to cooperate with the bottom surface of the material receiving seat 431 to limit the movement of the jacking member 4331 during jacking, so as to prevent the jacking member 4331 from colliding with the material pushing member 432 due to an excessively large lifting stroke, thereby further ensuring the safety of the mechanism.

As can be seen from fig. 11 and 12, in the present embodiment, the fitting portion 4321 includes a first portion 4322 and a second portion 4323 connected to each other, the first portion 4322 has a first ferrule port 4324 for being fitted on the shaft member 20, and the second portion 4323 has a second ferrule port 4325 into which the snap spring 10 is inserted and which communicates with the first ferrule port 4324. The second part 4323 is slidably disposed on the top surface of the material receiving seat 431, and the thickness of the second part 4323 is substantially the same as that of the circlip 10.

Specifically, the first ferrule 4324 has a shape and diameter matching that of the shaft member 20, which has a semi-circular cross-section. The width of the second portion 4323 matches the outer diameter of the snap spring 10, and the second snap ring opening 4325 has a V-shaped cross section, it can be understood that the second portion 4323 has a width matching the outer diameter of the snap spring 10, so that when the snap spring 10 abuts against the positioning wall of the positioning protrusion 4333 at the above-mentioned set position, and the lifting member 4331 is lifted to the highest position, the assembling portion 4321 moves toward the shaft member 20, and during the movement, the side wall of the second portion 4323 abuts against the positioning wall, the bottom surface of the second portion 4323 abuts against the top surface of the lifting member 4331, and the snap spring 10 is held in the second snap ring opening 4325.

As shown in fig. 4, 6 and 9, the material receiving seat 431 is provided with a pressing assembly 435 for limiting the movement of the clamp spring 10 in the conveying groove 4311. In this embodiment, the pressing assembly 435 includes a lower pressing plate 4351 disposed on the receiving seat 431 in a liftable manner and a lower pressing driving member 4352 for lifting the lower pressing plate 4351, the lower pressing plate 4351 is provided with a lower pressing rod 4353 for pressing the snap spring 10, the lower pressing driving member 4352 is, but not limited to, an air cylinder, and it is easily understood that, after the lifting member 4331 slides into the snap spring 10, the lower pressing driving member 4352 presses the lower pressing rod 4353 down to the snap spring 10 located behind the snap spring 10 (i.e. behind the snap spring 10 in the moving direction) to prevent the snap spring 10 from being fed.

as can be seen from fig. 4, 6 and 9, the material receiving seat 431 is provided with a guide block 436 for guiding the pushing member 432 to move, the guide block 436 is mounted on the material receiving seat 431 by any existing fixing method such as screws and welding, and the guide hole is provided with a hole for the pushing member 432 to pass through, so that the moving stability of the pushing member 432 is ensured, and the clamping and assembling effect is improved.

As can be seen from fig. 4, 6, and 9, the material receiving seat 431 is connected with a cover plate 437 for preventing the snap springs 10 from sliding out of the conveying grooves 4311 in the thickness direction of the snap springs 10, the cover plate 437 is mounted on the material receiving seat 431 by any existing fixing method such as screws and welding, and covers the conveying grooves 4311, so that the snap springs 10 can be placed to be separated from the conveying grooves 4311, stacking among the snap springs 10 can be avoided, and the ordered arrangement of the snap springs 10 is ensured.

Referring to fig. 4 to 12, the shaft positioning mechanism 420 includes a sleeve seat 421, a first clamping arm set 422 and a first arm driving member 423, the sleeve seat 421 has a sleeve surface 4211 on a top surface thereof for the snap spring 10 to slide, and the sleeve surface 4211 is formed with a sleeve hole 4212 for the end of the shaft member 20 to be inserted into; the first clamping arm set 422 is located above the nesting seat 421; the first arm driving member 423 is used for driving the first clamping arm set 422 to clamp the fixed shaft member 20, and the first arm driving member 423 is connected with the first clamping arm set 422. It should be noted that the top surface of the material receiving seat 431, the top surface of the set seat 421 (i.e., the set surface 4211), and the top surface of the lifting member 4331 at the lifting position (i.e., the highest lifting position) are all on the same plane.

In this embodiment, the nesting seat 421 and the first arm driving member 423 are both fixedly mounted on the supporting frame 410, the first arm driving member 423 is, but not limited to, a flat-type finger clamping cylinder, and the first arm driving member 423 includes a first cylinder body and two first parallel clamping jaws disposed on the first cylinder body; the first clamping arm group 422 includes two first clamping arms 4221, the two first clamping arms 4221 correspond to the two first parallel jaws one by one, the first clamping arms 4221 are fixedly mounted on the corresponding first parallel jaws, a hole corresponding to the shaft member 20 is formed on the inner side (the side facing the other first clamping arm 4221) of each first clamping arm 4221, and the shape and the diameter of the hole of the first clamping arm 4221 are matched with those of the shaft member 20. It is easy to understand that after the product 30 on the carrier plate 310 moves to above the nesting seat 421, the shaft member 20 corresponding to the nesting hole 4212 is pressed down, so that the bottom end of the shaft member 20 is inserted into the nesting hole 4212, and the first arm driving member 423 drives the two first clamping arms 4221 to move towards each other (i.e. the two clamping arms move towards each other), thereby clamping the fixed shaft member 20.

in yet another embodiment, the first arm actuator 423 is, but is not limited to, a Y-clamp finger cylinder.

Referring to fig. 4 to 12, in the present embodiment, a second clamping arm group 424 is disposed between the nesting seat 421 and the first clamping arm group 422, and the second clamping arm group 424 has two second clamping arms 4241; the shaft positioning mechanism 420 further includes a second arm driver 425 for driving the two second clamp arms 4241 to move relatively, and a guide hole 426 corresponding to the sheathing hole 4212 is formed between the two second clamp arms 4241 when they move toward each other, and an end of the shaft member 20 passes through the guide hole. The second arm actuator 425 is, but not limited to, a flat-type gripper finger cylinder, the second arm actuator 425 comprising a second cylinder and two second parallel gripper jaws disposed on the second cylinder; the two second parallel clamping jaws correspond to the two second clamping arms 4241 one by one respectively, and the second clamping arms 4241 are fixedly installed on the corresponding second parallel clamping jaws. It should be noted that, since the bottom end of the shaft member 20 is at a certain height from the seating surface 4211 before being depressed, the shaft member 20 is likely to be unable to smoothly slide into the seating hole 4212 on the seating surface 4211 due to radial displacement deviation of the shaft member 20 during the depression, and the guide hole 426 is formed before the depression of the shaft member 20 by the second clamp arm 4241, so that the shaft member 20 can be smoothly slid into the seating hole 4212 by the guide of the guide hole 426. It should be noted that after the first clamping arm 4221 clamps and fixes the shaft member 20, the second clamping arm 4241 moves back, and the pushing member 432 moves toward the shaft member 20 between the two second clamping arms 4241.

in yet another embodiment, the second arm actuator 425 is, but is not limited to, a Y-clamp finger cylinder.
