[0003] A pilot valve consists of a valve seat, a sealing ring, an iron core, a spring, a coil, and a snap-fit. Currently, pilot valves are primarily assembled manually. For example, the sealing ring is first placed on the valve seat, then the spring is placed in the groove at the top of the iron core. Next, the iron core and spring are placed on the valve seat, and finally the coil is engaged, using the snap-fit ​​to complete the assembly. This existing manual assembly method is inefficient and inefficient, resulting in high labor costs. Utility Model Content

[0042] Example 1:

[0043] like Figure 1-4 As shown, this embodiment provides an assembly mechanism 1, which can pre-assemble the coil 41, valve seat 42, and iron core spring assembly 43 of the pilot valve together, thereby facilitating the subsequent assembly of the snap-fit ​​45. Specifically, the assembly mechanism 1 includes a support base 11 and a pick-and-place unit 12. The support base 11 holds the coil 41, valve seat 42, and iron core spring assembly 43. The pick-and-place unit 12 is used to pick up the iron core spring assembly 43 and place it into the valve seat 42, and to pick up the coil 41 and place it onto the valve seat 42 where the iron core spring assembly 43 has already been placed, forming a... Figure 3 and Figure 4 The state shown (excluding buckle 45).

[0044] The support seat 11 can be fixed, with the coil 41, valve seat 42, and iron core spring assembly 43 placed manually; alternatively, the support seat 11 can be a rotating configuration, where a conveyor mechanism drives the support seat 11 to rotate, feeding the coil 41, valve seat 42, and iron core spring assembly 43 at multiple upstream stations. The coil 41 is the coil of the electromagnet. The iron core spring assembly 43 includes an iron core 431 and a spring 432 placed in a groove at the top of the iron core 431. When the coil 41 is energized, the iron core 431 moves upward, and the spring 432 is used to return the iron core 431 to its downward position. A sealing ring 44 for sealing is also placed on the valve seat 42.

[0045] Thus, the assembly mechanism 1 provided in this embodiment, compared with the prior art, automatically assembles the iron core spring assembly 43, valve seat 42 and coil 41 through the pick-and-place unit 12, reducing labor costs; moreover, during automatic assembly, the preparation / loading of each component of the next product can be carried out, and the assembly of the next product can be carried out after the current product is assembled, thereby improving production efficiency.

[0046] Preferably, in this embodiment, the coil 41, valve seat 42, and iron core spring assembly 43 are arranged in a straight line, which simplifies the pick-and-place unit 12. For example, the pick-and-place unit 12 can only include two linear modules: a linear module that moves along the height direction and a linear module that moves along the direction of the straight line arrangement, instead of linear modules in three directions.

[0047] The pick-and-place unit 12 includes a first pick-and-place module 121 and a second pick-and-place module 122. The first pick-and-place module 121 is used to clamp the iron core spring assembly 43 and place it into the valve seat 42. The second pick-and-place module 122 is used to clamp the coil 41 and place it onto the valve seat 42 where the iron core spring assembly 43 has already been placed. By setting up two pick-and-place modules corresponding to the two assembly actions, the complexity and cost of the pick-and-place unit 12 are further reduced. Specifically, the first pick-and-place module 121 includes a first gripper 1211, a first vertical movement module 1212, and a first horizontal movement module 1213. After the first gripper 1211 clamps the iron core spring assembly 43, it is driven upward by the first vertical movement module 1212, then driven towards the valve seat 42 by the first horizontal movement module 1213, and then driven downward by the first vertical movement module 1212 to place it into the valve seat 42. Finally, each module resets, or each module can remain in its current position until the second pick-and-place module 122 places the coil 41. The iron core spring assembly 43 enters the coil 41 and then resets, which is more conducive to the installation of the iron core spring assembly 43 and the coil 41. The second pick-and-place module 122 includes a second gripper 1221, a second vertical movement module 1222 and a second horizontal movement module 1223. After the second gripper 1221 picks up the coil 41, it is driven to move upward by the second vertical movement module 1222, and then driven to move towards the valve seat 42 by the second horizontal movement module 1223. Then it is driven to move downward by the second vertical movement module 1222 and placed on the valve seat 42. Finally, each module is reset.

[0048] As can be seen from the above, the assembly mechanism provided in this embodiment can realize the automatic assembly of the coil, valve seat and iron core spring assembly in the pilot valve, which is low in cost and high in efficiency.

[0049] Example 2:

[0050] like Figure 3-12 As shown, this embodiment provides a device including the assembly mechanism 1 described in Embodiment 1. The device in this embodiment further includes a transfer mechanism 2 and an assembly mechanism 3. The transfer mechanism 2 is used to transfer the assembled coil 41, valve seat 42, and iron core spring assembly 43 to the assembly mechanism 3. The assembly mechanism 3 is used to install a buckle 45 to engage and fix the coil 41 and valve seat 42, ultimately forming a… Figure 3-4 The state shown.

[0051] like Figure 6-10As shown, the assembly mechanism 3 includes a turntable 31, a vibratory feeding unit 32, and a pushing unit 33. The transfer mechanism 2 places the assembled coil 41, valve seat 42, and iron core spring assembly 43 onto the turntable 31, with the slots 411 on the first side of the coil 41 and valve seat 42 facing the pushing unit 33. The vibratory feeding unit 32 is used to sequentially vibrate and feed several clips 45, and the pushing unit 33 pushes the first clip 45 into the corresponding slots 411 on the first side of the coil 41 and valve seat 42 on the turntable 31. The turntable 31 can rotate 180 degrees horizontally so that the pushing unit 33 pushes the second clip 45 into the corresponding slots 411 on the second side of the coil 41 and valve seat 42 on the turntable 31. The two clips 45 achieve the engaging connection between the coil 41 and valve seat 42.

[0052] Furthermore, the vibratory feeding unit 32 includes a vibratory feeder 321 and a conveyor line 322. The conveyor line 322 is located at the output end of the vibratory feeder 321. The vibratory feeder 321 and the conveyor line 322 are equipped with guide structures, ensuring that the latches 45 are output vertically in sequence, and the output direction of the latches 45 is perpendicular to their latching direction. For example, as... Figure 10 As shown, the conveyor line 322 is provided with an L-shaped groove 323. The vertical side and lower edge of the C-shaped buckle 45 will enter the L-shaped groove 323 and be guided by the L-shaped groove 323. The upper edge of the buckle 45 is located on the upper outer end face of the L-shaped groove 323. The pushing unit 33 includes a first pushing module 331 and a second pushing module 332. After the buckle 45 passes through the conveyor line 322, it is first detected by the detection sensor. The push plate of the first pushing module 331 receives the buckle 45. The push plate is provided with a contoured groove to keep the buckle 45 in a vertical position and prevent it from tipping over. The first pushing module 331 pushes the buckle 45 to the side a certain distance in the direction of the buckle opening. After the buckle 45 is pushed to the side, the push plate of the second pushing module 332 pushes the buckle 45 toward the turntable 31. A contoured limiting groove is also provided on the pushing path to keep the buckle 45 in its vertical position. The buckle 45 is directly pushed into the corresponding slots 411 on the coil 41 and the valve seat 42 by the second pushing module 332. During the entire pushing process, the posture of the buckle 45 remains unchanged. The two locking edges of the C-shaped buckle 45 enter the slots 411 on the coil 41 and the valve seat 42 respectively to lock the two together. The outer edge of the slot 411 generally has a certain curvature to facilitate the insertion of the latch 45. Preferably, the pushing direction of the first pushing module 331 is perpendicular to the pushing direction of the second pushing module 332.

[0053] Furthermore, the assembly mechanism 3 also includes a sliding module 34, a rear limiting module 35, and a top limiting module 36. The sliding module 34 is used to move the turntable 31 away from the pushing unit 33 before assembling the buckle 45, and to move the turntable 31 closer to the pushing unit 33 during the assembly of the buckle 45. The rear limiting module 35 is located on the side of the turntable 31 facing away from the pushing unit 33. The rear limiting module 35 and the top limiting module 36 are used to limit the assembled coil 41, valve seat 42, and iron core spring assembly 43 during the assembly of the buckle 45. During assembly, the sliding module 34 first moves the turntable 31 closer to the pushing unit 33, so that the coil 41 and valve seat 42 on the turntable 31 are close to the output end of the pushing unit 33. After the first latch 45 is assembled, the sliding module 34 moves the turntable 31 away from the pushing unit 33, so that the turntable 31 can rotate horizontally 180 degrees with the coil 41 and valve seat 42 on it, and the coil 41 and valve seat 42 will not touch the output end of the pushing unit 33. Then the sliding module 34 moves the turntable 31 towards the pushing unit 33 again to assemble the second latch 45. Finally, the sliding module 34 moves the turntable 31 away from the conveying unit again to return to the initial position. When the buckle 45 is assembled, the rear limiting module 35 extends and presses against the back of the coil 41 and the valve seat 42; the top limiting module 36 includes an inverted U-shaped top limiting member 361, which can move to the top of the coil 41 for limiting, and can also limit the two sides of the coil 41, which facilitates the assembly of the buckle 45.

[0054] After the snap-fit ​​45 is assembled, the entire product needs to be clamped by the unloading mechanism (not shown in the figure) and placed in the next work station, such as the palletizing station; the unloading mechanism includes unloading grippers and a top moving module. Since the unloading mechanism is equipped with a top moving module, and the assembly mechanism 3 is also equipped with a pushing unit 33, a rear limiting module 35 and a top limiting module 36, this embodiment sets the turntable 31 to be movable to receive the assembled coil 41, valve seat 42 and iron core spring assembly 43.

[0055] Specifically, such as Figure 11-12As shown, the transfer mechanism 2 includes a first transfer module 21, a second transfer module 22, and a transfer module 23. The first transfer module 21 is used to clamp the assembled coil 41, valve seat 42, and iron core spring assembly 43 and drive them to move. The first transfer module 21 includes two linear modules, one vertical and one horizontal, as well as transfer grippers 211 and a top elastic clamping member 212. The transfer grippers 211 clamp the valve seat 42, and the top elastic clamping member 212 presses the coil 41. The assembled coil 41, valve seat 42, and iron core spring assembly 43 are transferred to the turntable 31 on the second transfer module 22 through the first transfer module 21. The second transfer module 22 is located at the bottom of the turntable 31 and carries the turntable 31, the sliding module 34 and the top limiting module 36. In the initial state, the turntable 31 is driven to the first transfer module 21 to receive the assembled coil 41, valve seat 42 and iron core spring assembly 43. The valve seat 42 is placed on the turntable 31 and the coil 41 is still pressed by the top elastic clamping member 212. The transfer module 23 includes a transfer gripper 231, which grips the coil 41 from the side. At this time, the first transfer module 21 can return to its original position. The top limiting module 36 includes a top limiting member 361, a vertical translation module 362, and a horizontal translation module 363. The vertical translation module 362 can drive the top limiting member 361 to move up and down, and the horizontal translation module 363 can drive the top limiting member 361 to move along the moving direction of the second transfer module 22. The top limiting member 361 can be driven to the top of the coil 41 for limiting and fixing the coil 41. At this time, the transfer gripper 231 can open, and then the second transfer module 22 drives the turntable 31 to move to the assembly station for buckle 45 assembly.

[0056] Preferably, the second pick-and-place module 122 used to clamp the coil 41 onto the valve seat 42 during assembly adopts the first transfer module 21 in the transfer mechanism 2. That is, the same module is used to realize the assembly action of placing the coil 41 onto the valve seat 42, and the transfer action of placing the assembled coil 41, valve seat 42, and iron core spring assembly 43 onto the turntable 31. The coil 41, valve seat 42, and iron core spring assembly 43 on the support 11 are arranged along a straight line, and the direction of this straight line is the direction of the slot 411 on the coil 41 and valve seat 42, which is the pushing direction of the buckle 45. In this way, after the coil 41 and valve seat 42 are transferred to the turntable 31, the turntable 31 does not need to be rotated to align the slot 411 with the buckle 45, which facilitates assembly.

[0057] As can be seen from the above, the device provided in this embodiment can realize the automatic assembly of the snap-fit ​​on the pilot valve, with a stable assembly structure and high assembly efficiency.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
