It should be noted that the divider in other structures is consistent with the structure of the above-mentioned dividing device a11, and one side of the discharging device is also configured with a micro-manipulator structure as mentioned above for transportation. They are all existing technologies, and their specific structures and working principles will not be described in detail here. Those skilled in the art can select and implement from the existing technologies according to actual operating conditions.

[0039] The outer side of the second rotating disk 13 is provided with an O-ring feeding device d, which specifically includes a vibrating disk, a straight vibrator, and a distributor, which is a prior art, and its specific structure and working principle are not described here in detail. Those skilled in the art can select and implement from the prior art according to the actual operation situation. When in use, the O-rings can be transported one by one to the input end side of the second rotating disk 13.

[0040] Furthermore, the second turntable 13 is provided with a transfer device 4 for carrying the O-ring, and the input end and output end of the second turntable 13 are provided with two transfer robots 2. The transfer robot 2 is provided with a clamp adapted for the O-ring, and the transfer robot 2 also includes a linear drive device capable of controlling the lateral and longitudinal movement of the clamp, which adopts structures such as cylinders, hydraulic cylinders, linear modules, and motor screws, which are existing technologies, and their specific structures and working principles are not repeated here. Those skilled in the art can select and implement from the existing technologies according to actual operating conditions.

[0041] The clamp located at the input end of the second turntable 13 is an air expansion chuck, and the clamp located at the output end of the second turntable 13 is a material rod 36 with a positioning structure. The transfer device 4 includes two tooling seats 45 located in the upper area of ​​the second turntable 13, and the tooling seats 45 are movably connected with a transfer chuck 46. The transfer chuck 46 is a multi-claw structure extending vertically upward. The air expansion chuck can transfer the oiled O-ring from the output end of the O-ring feeding device d and sleeve it on the transfer chuck 46. In this state, the O-ring is in a stretched state. The bottom of the transfer chuck 46 is provided with a passive limit lifting structure. After being pressed downward by the outside, the transfer chuck 46 can form a dislocation structure with the tooling seat 45, and the dislocation structure can cause the O-ring to fall off from the transfer chuck 46 and transfer to the material rod 36. The transfer robot 2 located at the output end of the second turntable 13 can transfer the O-ring located on the transfer device 4 and assemble it into the component threshold position located on the tooling table 14.

A movable block 43 is arranged above the fixed block 41, and two vertical guide rods 44 and a lifting rod 47 located at the middle position are arranged between the movable block 43 and the fixed block 41. The lifting rod 47 longitudinally penetrates the movable block 43 and the fixed block 41. The upper half of the lifting rod 47 is connected and fixed to the movable block 43 through a threaded structure, and the lower half of the lifting rod 47 is connected to the movable block 43 through a slidable bushing structure. The structure is slidably connected to the fixed block 41, and a lifting spring 471 is sleeved on the lifting rod 47. The lifting spring 471 is arranged between the movable block 43 and the fixed block 41. The top of the lifting rod 47 extends to the top of the turntable and is connected to the transfer chuck 46. The transfer chuck 46 is composed of four flange claws, which are combined to form a lateral limiting structure that can be clamped on the inner side of the O-ring. The transfer chuck 46, the lifting rod 47 and the movable block 43 constitute a passive limiting lifting structure. The lifting spring 471 can provide an upward reset driving force for the passive limiting lifting structure by virtue of its longitudinal expansion and contraction.

[0043] In order to ensure the lifting height of the passive limited lifting structure, a lifting sensor 48 is provided on the fixed block 41 for detecting the position when the movable block 43 moves up and down. The lifting sensor 48 is connected to the side wall of the fixed block 41 through an extension frame 481. The lifting sensor 48 is a position sensor, and its detection area corresponds to the lifting threshold position of the movable block 43. The extension frame 481 and the fixed block 41 are connected by strip holes and bolts, so that the assembly position of the lifting sensor 48 can be accurately and flexibly adjusted.

[0044] Furthermore, the tooling seat 45 is sleeved on the lateral outer side of the transfer chuck 46 with clearance fit, and the two can undergo longitudinal relative displacement. The tooling seat 45 is provided with an inner groove 451 located on the lateral outer side of the transfer chuck 46, and the inner groove 451 constitutes an anti-interference activity space for the gas expansion chuck to move downward at the tooling seat 45. In order to make the position of the tooling seat 45 more stable, a limiter 452 is provided between the bottom of the tooling seat 45 and the turntable. The limiter 452 in this embodiment is a vertical rod structure that is threadedly fixed to the bottom of the tooling seat 45, and a sink groove (not shown in the figure) is provided at the turntable and its corresponding position to form a limiter structure between the tooling seat 45 and the turntable.

[0045] Further, combined with Figure 6-8 As shown, the transfer manipulator 2 includes a bracket 21 connected to the frame 1, a movable module 22 is arranged on the bracket 21, a feeding module 3 is arranged on the movable module 22, the movable module 22 can drive the feeding module 3 to move horizontally and vertically (it adopts a cylinder, a hydraulic cylinder, a linear module, a motor screw and other structures), the feeding module 3 includes a base 31, a vertically arranged feeding cylinder 34 is arranged on the base 31, the transmission output end of the feeding cylinder 34 is connected to the clamp, and the feeding cylinder 34 can drive the clamp to move up and down. It should be noted that the displacement of the movable module 22 in each direction is accurately controlled by means of an in-place sensor.

[0046] Among them, the base 31 is a vertical plate structure, one side of which is provided with a horizontally arranged fixed plate 32, and the fixing plate 32 is connected to the positioning plate 33 through a connecting rod 42 below. The positioning plate 33 is parallel to the fixing plate 32 and is arranged at intervals. The positioning plate 33 is provided with a positioning hole 331 with a through hole structure (compatible with the transfer chuck 46 and the outer contour of the shell), and the positioning hole 331 vertically penetrates the positioning plate 33. The material rod 36 is longitudinally aligned with the positioning hole 331 and the top of the material rod 36 is connected to the fixing plate 32. The cylinder body of the feeding cylinder 34 is located above the fixing plate 32, and the telescopic rod of the feeding cylinder 34 is passed through the bottom of the fixing plate 32 and connected to the material rod 36 through a U-shaped clamp 35 and a sliding bushing 37.

[0047] Among them, Figure 8As shown, a positioning bottom groove 361 (whose contour matches the contour of the top of the core body) is provided at the bottom of the material rod 36, and a positioning groove 362 adapted to the O-ring is provided near the bottom area on the outer wall of the material rod 36, and the positioning groove 362 is used to accurately control the specific position of the O-ring sleeved in the bottom area of ​​the material rod 36. When in use, the positioning plate 33 first descends at the output station of the second turntable 13, and uses the positioning hole 331 and the transfer chuck 46 for positioning. The material rod 36 continues to descend to press the transfer chuck 46, and the transfer chuck 46 and the tooling seat 45 form a staggered structure. The staggered structure causes the O-ring to fall off the transfer chuck 46 and transfer to the positioning groove 362 on the material rod 36. Then, the material rod 36 carries the O-ring and transfers to the station on the adjacent side of the first turntable 12 and the second turntable 13 (the fourth station in this embodiment), and the positioning plate 33 and the material rod 36 descend synchronously The positioning plate 33 is positioned with the shell using the positioning hole 331, and the material rod 36 is positioned with the core body using the positioning bottom groove 361. At this time, the material rod 36 is constrained in the longitudinal direction and remains motionless, and the feeding cylinder 34 will continue to use its telescopic rod and U-shaped clamp 35 to control the sliding bushing 37 to move downward. During this process, the sliding bushing 37 will be relatively misaligned with the area below the material rod 36. This action will cause the sliding bushing 37 to push the O-ring located at the positioning groove 362 to the threshold position on the core body below when it continues to move downward, thereby completing the automatic assembly of the O-ring.

[0048] In the specific implementation process, by using the first turntable 12 as the main station transfer mechanism, the various components of the valve core are loaded in sequence, and are transferred and assembled with the help of the transfer mechanism, and finally output by the discharge device.

[0049] 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 the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
