After the height is reached, it is still clamped and carried on the valve seat full plate unit 31; the valve seat picking and placing unit 34 includes a valve seat picking and placing clamp 341 and a valve seat moving module 342. The valve seat picking and placing clamp 341 clamps a valve seat 102 and places the valve seat 102 in the second placement position 122 on the carrier 12 under the drive of the valve seat moving module 342. After the valve seats 102 on the valve seat material plate 311 are all clamped and placed, the valve seat transfer unit 33 is also used to transfer the empty valve seat material plate 311 to the valve seat empty plate unit 32 to be received by the valve seat empty plate unit 32.

[0075] Preferably, the coil feeding mechanism 2 and the valve seat feeding mechanism 3 of the present embodiment share a transverse movable module, that is, the coil movable module 242 in the coil feeding mechanism 2 and the valve seat movable module 342 in the valve seat feeding mechanism 3 share a transverse movable module, and two clamps and two vertical movable modules are arranged on this transverse movable module, which can save a certain amount of space and cost.

[0076] like Figure 1 , 12-14, the sealing ring feeding mechanism 4 of the present embodiment includes a sealing ring vibration feeding unit 41, a receiving seat 42 and a sealing ring picking and placing unit 43. The sealing ring vibration feeding unit 41 conveys a plurality of sealing rings 103 to the receiving seat 42 in sequence through a sealing ring vibration disk 411 and a sealing ring feeding line 412; the receiving seat 42 is provided with a receiving groove 421 to receive the sealing ring 103, and a receiving hole 422 is also formed in the receiving groove 421, and the outer diameter of the sealing ring 103 is larger than the aperture of the receiving hole 422. The sealing ring taking and placing unit 43 includes a sealing ring moving module 431, a sealing ring taking module 432 and a sealing ring lowering module 433. The sealing ring taking module 432 includes a receiving rod 4321, and the receiving rod 4321 can be driven downward to be inserted into the receiving hole 422, and also inserted into the middle of the sealing ring 103. The sealing ring 103 is an O-ring. The sealing ring 103 is hooped on the receiving rod 4321 under the action of its own elasticity. At this time, the sealing ring moving module 431 can drive the sealing ring 103 to move above the valve seat 102 on the carrier 12; the sealing ring lowering module 433 includes a sleeve 4331, and the sleeve 4331 is sleeved on the upper end of the receiving rod 4321. The sleeve 4331 can be driven downward to push the sealing ring 103 on the receiving rod 4321 so that it falls into the O-groove 1021 of the valve seat 102 on the carrier 12.

[0077] Furthermore, a blocking module 434 is provided on the side of the receiving seat 42. Before the sealing ring taking module 432 takes the sealing ring 103, the blocking plate 4341 of the blocking module 434 extends to the top of the receiving seat 42 to block the sealing ring 103 thereon, and the sealing ring vibration loading unit 41 stops working, thereby preventing the current sealing ring 103 on the receiving seat 42 from being squeezed by the subsequent sealing ring 103 and popping out of the receiving groove 421.

[0078] like Figure 1 , 15 -17, the core feeding mechanism 5 of the present embodiment includes a core vibration feeding unit 51, a core turning plate 52 and a core picking and placing unit 53. The core vibration feeding unit 51 conveys the cores 104 horizontally to the core turning plate 52 in sequence through the core vibration plate 511 and the core feeding line 512. The core turning plate 52 is provided with a core receiving groove 521. A part of the core 104 is placed in the core receiving groove 521, and the other part protrudes from the core receiving groove 521. The core turning plate 52 turns the core 104 90 degrees to a vertical state. The core picking and placing unit 53 includes a core moving module 531 and a core clamp 532. The core clamp 532 clamps the vertical core 104 and places the core 104 in the third placement position 123 on the carrier 12 under the drive of the core moving module 531.

[0079] Furthermore, a avoidance groove 54 is provided at the end of the iron core feeding line 512, and the avoidance groove 54 is used to avoid the protruding part of the iron core 104 when the iron core turning plate 52 turns over. The core flipping disk 52 preferably moves in forward and reverse directions, and a detection hole 55 is provided on the core flipping disk 52, and the detection hole 55 vertically penetrates the core receiving slot 521. A first detection sensor 56 is provided at the end of the core feeding line 512, which is preferably a photoelectric sensor, and its light can pass through the detection hole 55 to detect whether there is a core 104 in the core receiving slot 521; a second detection sensor 57 is also provided at the core flipping disk 52, which is preferably a photoelectric sensor, and its light is aimed at the protruding part of the core 104 in the vertical state after flipping; when the first detection sensor 56 detects that there is a core 104 in the core receiving slot 521, the core flipping disk 52 is controlled to rotate forward to flip the horizontal core 104 to a vertical state. When the second detection sensor 57 detects that the vertical core 104 is clamped away, the core flipping disk 52 is controlled to reverse, so that the next core 104 can be received through the core receiving slot 521.

[0080] like Figure 1 , 18 -20, the structures of the spring feeding mechanism 6 and the core feeding mechanism 5 of this embodiment are basically the same. Specifically, the spring feeding mechanism 6 includes a spring vibration feeding unit 61, a spring flip plate 62 and a spring pick-up and placement unit 63. The spring vibration feeding unit 61 horizontally conveys the spring 105 to the spring flip plate 62 in sequence through the spring vibration plate 611 and the spring feeding line 612. The spring flip plate 62 is provided with a spring receiving groove 621. A part of the spring 105 is placed in the spring receiving groove 621, and the other part protrudes from the spring receiving groove 621. The spring flip plate 62 flips the spring 105 90 degrees to a vertical state. The spring pick-up and placement unit 63 includes a spring moving module 631 and a spring clamp 632. The spring clamp 632 clamps the vertical spring 105, and under the drive of the spring moving module 631, the spring 105 is placed in the groove 1041 at the top of the core 104 on the third placement position 123 on the carrier 12 to form an iron core spring assembly. An insertion rod 64 is also provided in the middle of the spring clamp 632. When the spring clamp 632 clamps the spring 105, the insertion rod 64 is simultaneously inserted into the middle of the spring 105, so that when the spring 105 is lowered, the spring 105 can be lowered along the insertion rod 64; further, an auxiliary module 65 is also provided at the carrier 12 at the target position of the spring feeding mechanism 6, and the auxiliary module 65 includes an auxiliary clamp 651, and a guide groove 652 is formed on the auxiliary clamp 651 to facilitate the spring 105 to enter the top groove 1041 of the iron core 104.

[0081] In addition, an escape groove 54 is also provided at the end of the spring feeding line 612, and the escape groove 54 is used to avoid the protruding part of the spring 105 when the spring flip plate 62 flips. The spring flip disk 62 also preferably moves in forward and reverse directions. A detection hole 55 is also provided on the spring flip disk 62. The detection hole 55 vertically penetrates the spring receiving slot 621. A first detection sensor 56 is also provided at the end of the spring feeding line 612, which is preferably a photoelectric sensor. Its light can detect the spring 105 in the spring receiving slot 621 through the detection hole 55; a second detection sensor 57 is also provided at the spring flip disk 62, which is preferably a photoelectric sensor. Its light is aimed at the protruding part of the spring 105 that is in a vertical state after flipping; when the first detection sensor 56 detects that there is a spring 105 in the spring receiving slot 621, the flip disk is controlled to rotate forward to flip the horizontal spring 105 to a vertical state. When the second detection sensor 57 detects that the vertical spring 105 is clamped away, the spring flip disk 62 is controlled to reverse so that the next spring 105 can be received through the spring receiving slot 621.

[0082] Since the sealing ring 103 and the spring 105 have a certain elasticity, when they are placed at the corresponding position on the carrier 12, they may pop out due to their own elasticity. In this regard, the automatic assembly device for the pilot valve of this embodiment also includes a detection mechanism 8, such as Figure 1-2 As shown, the detection mechanism 8 is arranged on the work surface and close to the conveying mechanism 1, and includes a sealing ring detection module 81 and a spring detection module 82. The two detection modules are preferably cameras, wherein the sealing ring detection module 81 is located downstream of the sealing ring feeding mechanism 4, for example, between the sealing ring feeding mechanism 4 and the iron core feeding mechanism 5, or between the iron core feeding mechanism 5 and the spring feeding mechanism 6; the spring detection module 82 is located downstream of the spring feeding mechanism 6, for example, between the spring feeding mechanism 6 and the buckle feeding and assembly mechanism 7. When an abnormal situation is detected, an alarm can be given in time to prevent parts from being lost during product assembly.

[0083] like Figure 1 , 21 -29, the buckle feeding and assembly mechanism 7 of this embodiment includes an assembly unit 71, which is used to place the core spring assembly on the carrier 12 into the valve seat 102, and to place the coil 101 on the valve seat 102 on which the core spring assembly has been placed, so that the coil 101, valve seat 102, sealing ring 103 and core spring assembly of the pilot valve 10 are pre-assembled together, thereby facilitating the subsequent assembly of the buckle 106. Preferably, the coil 101, valve seat 102 and core spring assembly on the carrier 12 are arranged along a straight line, which can simplify the moving module of the assembly unit 71 for taking and placing.

[0084] The assembly unit 71 includes a first assembly movable module 711 and a first assembly clamp 712. The first assembly clamp 712 is used to clamp the core spring assembly on the carrier 12 and place it in the valve seat 102 under the drive of the first assembly movable module 711; specifically, the first assembly movable module 711 includes a first vertical movement module 7111 and a first horizontal movement module 7112. After the first assembly clamp 712 clamps the core spring assembly, it is driven by the first vertical movement module 7111 to move upward, and then driven by the first horizontal movement module 7112 to move toward the valve seat 102, and then driven by the first vertical movement module 7111 to move downward and be placed in the valve seat 102. Each module can remain in the current position and reset when the coil 101 is placed later so that the core spring assembly enters the coil 101. This is more conducive to the installation of the core spring assembly and the coil 101. Because the iron core 104 slides with the inner wall of the coil 101, and has a certain circumferential spacing with the placement groove 1022 on the valve seat 102, that is, relative to the placement groove 1022 of the valve seat 102, the iron core 104 is closer to the inner wall of the coil 101. If the iron core 104 is directly placed in the valve seat 102, it is difficult to ensure that the iron core 104 is in a vertical state. Therefore, this embodiment sets a third placement position 123 on the carrier 12 to place the iron core 104, which can maintain it in a vertical state; in addition, when the iron core spring assembly is placed in the valve seat 102 through the first assembly moving module 711 and the first assembly clamp 712, the iron core 104 maintains a vertical posture, so that when the coil 101 is vertically assembled on the valve seat 102, the iron core 104 can smoothly enter the coil 101 and slide with the inner wall of the coil 101 to ensure that the product is accurately and reliably assembled.

[0085] The assembly unit 71 further includes a second assembly moving module 713 and a second assembly clamping jaw 714. The second assembly clamping jaw 714 clamps the coil 101 and places it on the valve seat 102 on which the core spring assembly has been placed. Specifically, the second assembly moving module 713 includes a second vertical moving module 7131 and a second horizontal moving module 7132. After the second assembly clamping jaw 714 clamps the coil 101, it is driven by the second vertical moving module 7131 to move upward, then driven by the second horizontal moving module 7132 to move toward the valve seat 102, and then driven by the second vertical moving module 7131 to move downward and place it on the valve seat 102.

[0086] Furthermore, the buckle feeding and assembly mechanism 7 of the present embodiment also includes a transfer unit 72, a rotating disk 73, a buckle vibration feeding unit 74, a pushing unit 75 and a limiting unit 76. The transfer unit 72 is used to cooperate with placing the assembled coil 101, valve seat 102, sealing ring 103 and core spring assembly on the rotating disk 73, and the rotating disk 73 is correspondingly provided with a notch to accommodate the valve seat 102. The buckle vibration feeding unit 74 is used to transport the buckle 106 to the pushing unit 75, and the pushing unit 75 is used to The received buckle 106 is pushed into the slot 1011 corresponding to the first side of the coil 101 and the valve seat 102 on the rotating disk 73. The rotating disk 73 can rotate horizontally 180 degrees. The pushing unit 75 can push the next buckle 106 into the slot 1011 corresponding to the second side of the coil 101 and the valve seat 102 on the rotating disk 73. The coil 101 and the valve seat 102 are connected by these two buckles 106. The limiting unit 76 is used to limit the coil 101 and the valve seat 102 when pushing the buckle 106.

[0087] Specifically, the buckle vibration feeding unit 74 includes a buckle vibration plate 741 and a buckle feeding line 742. The buckle feeding line 742 is arranged at the output end of the buckle vibration plate 741. The buckle vibration plate 741 and the buckle feeding line 742 are provided with a buckle guide structure, so that the buckles 106 are output vertically in sequence, and the output direction of the buckles 106 is perpendicular to the direction of the buckle port. Fig. 27As shown, an L-shaped groove 7421 is provided on the buckle feeding line 742. The vertical side and the lower clamping edge of the C-shaped buckle 106 will enter the L-shaped groove 7421 and be guided by the L-shaped groove 7421. The upper clamping edge of the buckle 106 is located at the upper outer end surface of the L-shaped groove 7421. The pushing unit 75 includes a first pushing module 751 and a second pushing module 752. After the buckle 106 passes through the buckle feeding line 742, it is first detected by the buckle detection sensor 753. The push plate at the output end of the first pushing module 751 receives the buckle 106. The middle part of the push plate is provided with a roughly C-shaped notch that imitates the buckle 106 so that the buckle 106 maintains a vertical posture and does not fall over. The first pushing module 751 is pushed sideways a certain distance toward the clamping direction of the buckle 106; the buckle 106 is pushed After reaching the side, the push plate at the output end of the second pushing module 752 is pushed toward the rotating disk 73. A roughly C-shaped limiting groove that imitates the buckle 106 is also provided on this pushing path to keep the buckle 106 in its vertical posture. The buckle 106 is directly pushed into the corresponding slots 1011 on the coil 101 and the valve seat 102 by the second pushing module 752. During the entire pushing process, the posture of the buckle 106 remains unchanged, and the two clamping edges of the C-shaped buckle 106 respectively enter the slots 1011 on the coil 101 and the valve seat 102 to clamp the two. The outer edge of the slot 1011 may have a certain curvature, which is more convenient for pushing the buckle 106. The pushing direction of the first pushing module 751 and the pushing direction of the second pushing module 752 are preferably perpendicular to each other.

[0088] Furthermore, the limiting unit 76 includes a rear limiting module 761 and a top limiting module 762. The rear limiting module 761 is arranged on the side of the turntable facing away from the pushing unit 75. The rear limiting module 761 and the top limiting module 762 are used to limit the assembled coil 101, valve seat 102 and iron core spring assembly when assembling the buckle 106.

[0089] The bottom of the rotating disk 73 is also provided with a sliding module 77, which is used to drive the rotating disk 73 away from the pushing unit 75 before assembling the buckle 106, and to drive the rotating disk 73 close to the pushing unit 75 when assembling the buckle 106. During assembly, the sliding module 77 first drives the rotating disk 73 to move close to the pushing unit 75, so that the coil 101 and the valve seat 102 on the rotating disk 73 are close to the output end of the pushing unit 75; after the first buckle 106 is assembled, the sliding module 77 drives the rotating disk 73 away from the pushing unit 75, so that the rotating disk 73 can rotate horizontally 180 degrees with the coil 101 and the valve seat 102 thereon, and the coil 101 and the valve seat 102 will not touch the output end of the pushing unit 75; then the sliding module 77 drives the rotating disk 73 to move toward the pushing unit 75 again to assemble the second buckle 106; finally, the sliding module 77 drives the rotating disk 73 to retreat away from the conveying unit 11 again. When the buckle 106 is assembled, the rear limiting module 761 extends out to support the back of the coil 101 and the valve seat 102; the top limiting module 762 includes an inverted U-shaped top limiting piece 7621, which can move to the top of the coil 101 for limiting, and can also limit the two side edges of the coil 101, so as to facilitate the assembly of the buckle 106.

[0090] like Figure 1 and Fig.30 As shown, the pilot valve automatic assembly equipment of this embodiment also includes a material unloading mechanism 9, which is also located on the work surface, and is used to unload the assembled pilot valve 10. Specifically, the material unloading mechanism 9 includes a pilot valve full tray unit 91, a pilot valve empty tray unit 92, a pilot valve transfer unit 93, and a pilot valve pick-up and placement unit 94. The pilot valve transfer unit 93 is used to receive at least one empty pilot valve material tray 911 from the pilot valve empty tray unit 92 and move it to the pilot valve pick-up and placement unit 94. After the remaining empty pilot valve material trays 911 are lowered to a certain height, they are continued to be clamped and carried by the pilot valve empty tray unit 92; the pilot valve pick-up and placement unit 94 includes a pilot valve pick-up and placement clamp 9 41 and the pilot valve moving module 942, the pilot valve picking and placing clamp 941 clamps the assembled pilot valve 10 with two buckles 106 from the rotating disk 73 and places the pilot valve 10 on the pilot valve material tray 911 under the drive of the pilot valve moving module 942. When the pilot valve material tray 911 is full of pilot valves 10, the pilot valve transfer unit 93 is also used to transfer the full pilot valve material tray 911 to the pilot valve full tray unit 91 to be received by the pilot valve full tray unit 91.

[0091] Since the unloading mechanism 9 is provided with a pilot valve picking-up and placing unit 94, and the pilot valve picking-up and placing unit 94 is required to pick up and place the pilot valve 10 from the top, it must be arranged at a high place; in addition, the buckle loading and assembly mechanism 7 also includes a pushing unit 75 and a limiting unit 76. For the sake of space arrangement, this embodiment also provides a rotating disk 73 that can be moved to receive the assembled coil 101, valve seat 102 and iron core spring assembly.

[0092] Specifically, the transfer unit 72 includes a first transfer module 721, a second transfer module 722 and an intermediate module 723, wherein the first transfer module 721 is used to clamp the assembled coil 101, valve seat 102 and iron core spring assembly and drive them to move, and the first transfer module 721 includes two vertical and horizontal linear modules and a transfer clamp 7211 and a top elastic clamp 7212. The valve seat 102 is clamped by the transfer clamp 7211, and the top elastic clamp 7212 presses the top of the coil 101. The assembled coil 101, valve seat 102 and iron core spring assembly are transferred to the rotating disk 73 on the second transfer module 722 through the first transfer module 721. The second transfer module 722 is arranged at the bottom of the rotating disk 73, and carries the rotating disk 73, the top limit module 762 and the sliding module 77; in the initial state, the rotating disk 73 is driven to the first transfer module 721 to receive the assembled coil 101, valve seat 102 and iron core spring assembly, the valve seat 102 is placed on the rotating disk 73, and the coil 101 is still tightened by the top elastic clamping piece 7212. The middle module 723 includes a middle clamping jaw 7231, which clamps the coil 101 from the side. At this time, the first transfer module 721 can return to its position; the top limiting module 762 includes a top limiting member 7621, a vertical translation module 7622 and a horizontal translation module 7623. The vertical translation module 7622 can drive the top limiting member 7621 to move up and down, and the horizontal translation module 7623 can drive the top limiting member 7621 to move along the moving direction of the second transfer module 722. The top limiting member 7621 can be driven to the top of the coil 101 for limiting and fixing the coil 101. At this time, the middle clamping jaw 7231 can be opened, and then the second transfer module 722 drives the rotating disk 73 to move to the assembly station for buckle 106 assembly.

[0093] Preferably, the second assembly moving module 713 and the second assembly clamping jaw 714 for clamping the coil 101 and placing it on the valve seat 102 adopt the first transfer module 721 in the transfer unit 72, that is, in addition to the transfer action of placing the assembled coil 101, valve seat 102 and iron core spring assembly on the rotating disk 73 by the first transfer module 721, the assembly action of placing the coil 101 on the valve seat 102 is also performed by the two horizontal and vertical linear modules and the transfer clamping jaw 7211 in the first transfer module 721, which can save a certain amount of space and cost. In addition, preferably, the coil 101, valve seat 102 and iron core spring assembly on the bearing seat are arranged along a straight line, and the direction of the straight line is the direction of the card slot 1011 on the coil 101 and the valve seat 102, that is, the push-in direction of the buckle 106, so that after the coil 101 and the valve seat 102 are transferred to the rotating disk 73, the rotating disk 73 does not need to be rotated to align its card slot 1011 with the buckle 106, which is convenient for assembly.

[0094] It can be seen from the above content that the automatic assembly equipment for pilot valves provided in this embodiment can realize the automatic assembly of pilot valves and has the characteristics of reliable assembly structure and high assembly efficiency.
