Its main function is to reduce or eliminate vibrations generated by a mechanical structure when subjected to external excitation by absorbing, dissipating, or transferring the vibration energy in the system, thereby improving the stability, safety, and service life of the system. The damper valve core is composed of valve plates with different diameters stacked together and is a key component in the damper, mainly used to control the flow of fluid, and its design has a direct impact on the damping effect of the damper.

[0056] Embodiment 1

[0057] As Figure 1-13As shown in the figure, this embodiment provides an automatic production system for a damper valve core to produce the valve core 1 of the damper. The valve core 1 is composed of a valve seat 11, several valve plates 12, small gaskets 13, large gaskets 14, and an air intake disc 15. The components are fixed by the cooperation of a clamping member 16 arranged at the bottom of the valve core 1 and a fastening member 17 arranged at the top of the valve core 1. The system includes a loading fixture 2 and a circular conveying device 3 that drives the loading fixture 2 to move sequentially, and also includes: multiple groups of sequentially arranged piece-by-piece loading devices 4 that automatically slice the valve plates 12 using magnetic force and transfer them to the loading fixture 2; an ejecting loading device 5 that ejects the small gaskets 13 one by one from the bottom and transfers them to the loading fixture 2; a sorting loading device 6 with three groups that automatically sorts and inputs the clamping member 16, large gasket 14, and fastening member 17 one by one and transfers the workpieces to the loading fixture 2 in sequence. Several of the piece-by-piece loading devices 4, ejecting loading devices 5, and sorting loading devices 6 are arranged along the conveying device 3 according to the installation sequence of the components of the valve core 1, forming a circumferentially arranged and end-to-end connected valve seat bottom loading area 100, valve plate loading area 200, valve seat loading area 300, combined assembly area 400, and discharging area 500. The loading fixture 2 is circumferentially evenly distributed on the conveying device 3 and moves intermittently in a circular manner along the conveying device 3. Each area transfers the valve core components on each device to the loading fixture 2 conveyed to the corresponding position by the conveying device 3 in sequence, and completes the assembly of the valve core 1 in sequence.

[0058] By setting multiple loading methods such as the piece-by-piece loading device 4, ejecting loading device 5, and sorting loading device 6, the precise loading and assembly of each component of the valve core 1 are ensured, and the working areas are divided according to the assembly sequence of each part of the valve core 1, effectively improving the degree of automation of production and the product quality.

[0059] As Figure 4 , 9 shown, the loading fixture 2 sequentially includes a first loading position 21, a second loading position 22, and a third loading position 23 along the conveying direction. The first loading position 21, the second loading position 22, and the third loading position 23 are all provided with limit posts 24, and the limit post 24 at the second loading position 22 is movably arranged; a lifting mechanism 25 for driving the limit post 24 at the second loading position 22 to slide up and down is arranged below the conveying device 3, and the lifting mechanism 25 only jacks up the limit post 24 at the second loading position 22 when the second loading position 22 needs to be loaded.

[0060] As Figure 5-13As shown, the piece feeding device 4, the ejecting feeding device 5, and the sorting feeding device 6 are all provided with a material taking mechanism 7 and a driving component 8 for driving the movement of the material taking mechanism 7. The driving component 8 is installed inside the conveying device 3. The material taking mechanism 7 includes a material taking part 71 designed corresponding to the outer shapes of each component to clamp each component. In this embodiment, the material taking part 71 is provided in two forms: a clamping jaw and a suction tool.

[0061] As Figure 5 , 6 shown, the piece feeding device 4 is arranged on the other side of the conveying device 3 relative to the driving component 8, and further includes: a rotating mechanism 41 with rod grooves 411 at both ends. The rod groove 411 at the end facing the conveying device 3 is the feeding position, and the other end is the replenishing position; a rod 42 with workpieces strung thereon, and its bottom is installed in the rod groove 411; a piece sorting mechanism 43 including a magnetic part 431 corresponding to the rod 42 at the feeding position and a first driving part 432 for driving the lifting of the magnetic part 431. The magnetic part 431 is connected to the driving end of the first driving part 432 through components such as a mounting plate. Using the principle of a magnetic separator, the workpieces on the rod 42 are magnetized to automatically separate the pieces. When the magnetic part 431 moves upward, the separated pieces rise to the top of the rod 42, avoiding the problem of clamping multiple pieces of workpieces at one time. The material taking part 71 of the piece feeding device 4 is a suction tool, and the suction tool sucks the pieces separated from the rod 42 at the feeding position by the piece sorting mechanism 43. The driving component 8 drives the suction tool to move cyclically between the rod 42 at the feeding position and the feeding jig 2. A detection component 433 is also arranged on the side of the rod 42 at the feeding position. The detection component 433 above is used to detect whether there is a workpiece above, that is, to detect whether the magnetic part has successfully separated the pieces. The detection component 433 below is used to detect whether there are still workpieces on the rod 42. If the workpieces are consumed, a signal will be sent to remind the worker. The worker can replace the inner and outer rods 42 through the rotating mechanism 41 for replenishment. The empty rod 42 on the outer side can directly replace the rod 42 with the workpieces strung. It should be noted that due to the property that the magnetic separator can only separate sheet-like workpieces, for thicker workpieces or irregular workpieces, its separation effect is poor. Therefore, in this embodiment, the piece feeding device 4 is only used for feeding thinner sheet-like workpieces.

[0062] As Figure 7 , 8As shown, the ejecting and loading device 5 is arranged on the other side of the conveying device 3 relative to the driving assembly 8, and further includes: a feeding mechanism 51, which is longitudinally arranged and discharges materials from the discharging port 511 at the bottom; a pushing mechanism 52, including a pushing plate 521 slidably arranged close to the discharging port 511 under the feeding mechanism 51, a second driving member 522 for driving the pushing plate 521 to move horizontally, and a receiving port 523 corresponding to the discharging port 511; the material taking part 71 of the ejecting and loading device 5 is a clamping jaw, and the clamping jaw clamps the material piece horizontally ejected in the receiving port 523 of the pushing mechanism 52, and the driving assembly 8 drives the clamping jaw to move cyclically between the receiving port 523 and the loading fixture 2. In this embodiment, it is difficult for the piecewise loading device 4 to position and grasp smaller sheet-like material pieces, so the ejecting and loading device 5 is provided to accurately position and grasp small sheet-like material pieces.

[0063] As Figure 9-11 shown, the sorting and loading device 6 is arranged on the other side of the conveying device 3 relative to the driving assembly 8, and further includes: a sorting mechanism 61, including a vibrating bowl 611 and a guide rail groove 612 arranged at the outlet of the vibrating bowl 611; an isolating mechanism 62, including a receiving part 621 arranged at the outlet of the guide rail groove 612, a blocking part 622 arranged on the side of the receiving part 621 facing the guide rail groove 612, and a third driving member 623 for driving the receiving part 621 to slide closely against the blocking part 622; the material taking part 71 of the sorting and loading device 6 is a clamping jaw, and the clamping jaw clamps the material piece horizontally transferred by the isolating mechanism 62, and the driving assembly 8 drives the clamping jaw to move cyclically between the horizontally transferred material piece and the loading fixture 2. In this embodiment, the sorting and loading device 6 mainly feeds irregular parts and thicker sheet-like material pieces. The material pieces are automatically aligned by the vibration of the vibrating bowl 611, and the worker only needs to put the material pieces into the vibrating bowl 611.

[0064] As Figure 3 shown, in the valve seat bottom feeding area 100, a sorting and loading device 6 for transferring the clamping member 16 to the second feeding position 22 and a piecewise loading device 4 for transferring the intake air disc 15 to the second feeding position are arranged in sequence along the conveying direction. The valve seat bottom feeding area 100 further includes a detection component for detecting whether the shape and installation position of the intake air disc 15 are accurate. The detection component is arranged on one side of the conveying device 3 and in front of the piecewise loading device 6.

[0065] As Figure 3As shown, a plurality of sheet material feeding devices 4 for transferring the valve sheets 12 to the first feeding position 21 are sequentially arranged in the valve sheet feeding area 200 along the conveying direction. The sheet material feeding devices 4 are redundant, and the number of valve sheets 12 of the valve core 1 can be changed according to actual requirements. Since there is redundancy, when a sheet material feeding device 4 is damaged, the redundant sheet material feeding device 4 can replace it in time. Detection components are arranged in the middle and at the tail of the valve sheet feeding area 200 to detect the position and quantity of the valve sheets to ensure accuracy.

[0066] As Figure 10 , 11 shown, the valve seat feeding area 300 includes a sorting and feeding device 6 for transferring the valve seats 11 to the third feeding position 23. A cross beam 63 and a detection component 64 mounted on the cross beam 63 are added to the sorting and feeding device 6 in the valve seat feeding area 300. Another set of driving components 8 and a material taking mechanism 7 are mounted on the cross beam 63. The added driving components 8 and the material taking mechanism 7 are responsible for clamping the valve seat 11 under the first detection component 64, and the original driving components 8 and the material taking mechanism 7 are responsible for clamping out the valve seat 11 under the first detection component 64. If the detection is qualified, the valve seat 11 is clamped to the third feeding position 23, and if it is unqualified, the valve seat 11 is clamped to the waste outlet 65 for waste treatment.

[0067] As Figure 3 , 12 shown, the combined assembly area 400 is sequentially provided with a material transfer device 9 for transferring all the components on the third feeding position 23 and the first feeding position 21 to the second feeding position 22 along the conveying direction, an ejecting feeding device 5 for transferring the small gaskets 13 to the second feeding position 22, a sorting and feeding device 6 for transferring the large gaskets 14 to the second feeding position 22, a sorting and feeding device 6 for transferring the fasteners 17 to the second feeding position 22, and a pressing device 10 for pressing the male end of the fastener 17 and the female end of the clamping member 16. The first feeding position 21, the second feeding position 22, and the third feeding position 23 are on the same straight line and the distances between adjacent feeding positions are equal. The material transfer device 9 includes a transverse movement mechanism 91 and a material clamping mechanism 92. The material clamping mechanism 92 is provided with two pairs of clamping jaws with the same spacing as that between adjacent feeding positions. During operation, the clamping jaws on the right clamp the valve seat 11, the transverse movement mechanism 91 drives the material clamping mechanism 92 to move the valve seat above the second feeding position 22. At this time, the clamping jaws on the left are above the first feeding position 21. When the clamping jaws on the right release the valve seat 11, the clamping jaws on the left clamp the valve sheet 12. Then the transverse movement mechanism 91 drives the material clamping mechanism 92 to move the valve sheet 12 above the second feeding position 22. At this time, the clamping jaws on the right return above the third feeding position 23. After the clamping jaws on the left release the valve sheet 12, the conveying device 3 drives the feeding fixture 2 into the next process, and the next feeding fixture 2 moves below the material transfer device 9 for cyclic operation.

[0068] As Figure 3As shown, the discharging area 500 includes a conveyor belt 501 and a discharging jig 502 disposed on the conveyor belt 501. The conveying device 3 is circular, and the bottom seat feeding area 100, the valve plate feeding area 200, the seat feeding area 300, the combined assembly area 400, and the discharging area 500 are arranged circumferentially along the conveying device 3 and are connected end to end. The feeding jigs 2 are circumferentially and evenly distributed on the conveying device 3 and move intermittently and circularly along the conveying device 3.

[0069] By setting the conveying device 3 to be circular, the floor area of the present invention can be saved, the structure of the production system can be made more compact, the closed-loop control of the production line can be realized, the land use cost of the enterprise can be reduced, and the moving distance of the circular conveying device 3 is also smaller, saving energy consumption and having higher production efficiency at the same time.

[0070] Embodiment 2

[0071] As Figure 14 shown, a kind of automatic production process of the damper valve core of Embodiment 2 of the present invention is described with reference to Embodiment 1.

[0072] An automatic production process of a damper valve core, based on the above-mentioned automatic production system of a damper valve core, includes the following steps:

[0073] Step 1: Feeding the bottom components of the seat 11. The feeding jig 2 moves with the conveying device 3 to the bottom seat feeding area 100 of the seat, pauses at the sorting and feeding device 6, the lifting mechanism 25 jacks up the limit post 24 at the second feeding position 22 of the feeding jig 2, and then the sorting and feeding device 6 transfers the clamping member 16 to the second feeding position 22 and slews it on the limit post 24. After completion, the lifting mechanism 25 lowers the limit post 24. The conveying device 3 moves the feeding jig 2 to the slicing and feeding device 4 and pauses. The lifting mechanism 25 jacks up the limit post 24 at the second feeding position 22 of the feeding jig 2 again. Then the slicing and feeding device 4 transfers the air intake disc 15 to the second feeding position 22 and slews it on the limit post 24. After completion, the lifting mechanism 25 lowers the limit post 24;

[0074] Step 2: Feeding the valve plate 12. The feeding jig 2 moves with the conveying device 3 from the bottom seat feeding area 100 of the seat to the valve plate feeding area 200, pauses at all slicing and feeding devices 4 in turn. At this time, the slicing and feeding device 4 to be sorted transfers the valve plate 12 to the limit post 24 sleeved on the first feeding position 21 of the feeding jig 2, and the valve plates 12 transferred by the slicing and feeding devices 4 located behind are sequentially placed above the valve plates 12 transferred by the slicing and feeding devices 4 in front. It should be noted that because the slicing and feeding devices 4 are provided with redundancy, not all the slicing and feeding devices 4 need to be fed in this step;

[0075] Step 3: Feeding the valve seat 11. The feeding jig 2 moves from the valve plate feeding area 200 to the valve seat feeding area 300 along with the conveying device 3, pauses at the sorting and feeding device 6, and the sorting and feeding device 6 transfers the valve seat 11 to the limiting column 24 at the third feeding position 23;

[0076] Step 4: Assembly. The feeding jig 2 moves from the valve seat feeding area 300 to the assembly area 400 along with the conveying device 3, pauses at the material transfer device 9. The material transfer device 9 successively transfers all the components at the third feeding position 23 and the first feeding position 21 to the second feeding position 22. After completion, the conveying device 3 moves the feeding jig 2 to the ejecting and feeding device 5. The ejecting and feeding device 5 transfers the small gasket 13 to the second feeding position 22. After completion, the conveying device 3 transfers the feeding jig 2 to the sorting and feeding device 6. The sorting and feeding device 6 transfers the large gasket 14 to the second feeding position 22. After completion, the conveying device 3 transfers the feeding jig 2 to the next sorting and feeding device 6. The sorting and feeding device 6 here transfers the fastener 17 to the second feeding position 22 and pre-presses the fastener 17. After completion, the conveying device 3 transfers the feeding jig 2 to the pressing device 10 to press the male end of the fastener 17 and the female end of the clamping member 16 to complete the assembly of the valve core 1;

[0077] Step 5: Discharging the valve core 1. The feeding jig 2 moves from the assembly area 400 to the discharging area 500 along with the conveying device 3. The assembled valve core 1 is transferred to the discharging jig 502 here and output by the conveyor belt 501.

[0078] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
