The magnetic conductor has a second accommodation space, and one end of the second accommodation space along the axial direction of the magnetic conductor has an opening. The skeleton is provided with a plug hole, and the pin is inserted into the plug hole in a plug-in fit. Then the pin is bent, and then the skeleton with the bent pin is installed in the second accommodation space through the second opening. Finally, the static iron core is riveted to the skeleton from the first opening, thereby completing the assembly operation of the oil valve assembly.

[0059] Figure 1 Schematically shows a flow diagram of the assembly method according to an embodiment of the present invention. The present invention provides an assembly method, which is implemented based on the Figure 7 oil valve assembly device 100 as shown. Among them, the oil valve of the present invention includes a skeleton, a pin, an enameled wire, a magnetic conductor, and a static iron core.

[0060] As Figure 7 , 8 and 13 show, the oil valve assembly device 100 in the present invention includes a base 10, a first assembly mechanism 20, a winding mechanism 30, and a second assembly mechanism 40. A transfer member 51 is provided on the base 10, and the transfer member 51 is used to transfer materials in a first direction. The first assembly mechanism 20 is provided on the base 10 and includes an assembly table 21, a first assembly component 22, and a first moving component 23. The first assembly component 22 and the first moving component 23 are respectively provided on the same side of the assembly table 21 along a second direction. The assembly table 21 is provided with a flow channel tooling for placing the skeleton. The first assembly component 22 is used to clamp the pin and insert the pin into the skeleton to form a first assembly. The first moving component 23 is used to move the first assembly to the transfer member 51, and the first direction and the second direction intersect.

[0061] Further, the winding mechanism 30 is disposed on the base 10 and is located on one side of the assembly table 21 along the first direction, and is configured to wind enameled wire around the outer periphery of the first assembly transported by the transfer member 51 to form a second assembly. The second assembly mechanism 40 is disposed on the base 10 and is located on the side of the winding mechanism 30 away from the assembly table 21. The second assembly mechanism 40 includes a loading turntable 41, a second assembly component, and a third assembly component. The loading turntable 41 has an operation station 411. The second assembly component and the third assembly component are disposed on the circumferential outer side of the loading turntable 41. The loading turntable 41 is rotatable. The operation station 411 is configured to receive the second assembly on the transfer member 51. The second assembly component is configured to assemble a magnetic conductor to the second assembly. The third assembly component is configured to fixedly connect the static iron core to the magnetic conductor of the second assembly.

[0062] As Figure 1 shown, the assembly method includes:

[0063] S1: Transport the skeleton to the multi-channel tooling on the assembly table 21;

[0064] S2: Clamp the pin to the pin turntable 222, rotate the pin turntable 222 to a position corresponding to the skeleton on the multi-channel tooling, and insert the pin into the skeleton to form a first assembly;

[0065] S3: Move the first assembly to the winding mechanism 30, and wind enameled wire around the skeleton through the winding mechanism 30 to form a second assembly;

[0066] S4: Move the second assembly to the loading turntable 41;

[0067] S5: Transport the magnetic conductor to the loading turntable 41, clamp the second assembly, and insert the skeleton of the second assembly into the magnetic conductor;

[0068] S6: Clamp the static iron core to the open end of the magnetic conductor, and fixedly connect the static iron core to the magnetic conductor to form an oil valve.

[0069] Based on the above oil valve assembly device and using the assembly method in the present technical solution, the skeleton and the pin of the oil valve can be first inserted, then enameled wire can be wound around the skeleton, then the magnetic conductor can be assembled outside the skeleton, and finally the static iron core can be assembled onto the skeleton, which can achieve automatic assembly in sequence, improving the degree of automation of assembly and the operation efficiency.

[0070] Further, in step S1, transporting the skeleton to the multi-channel tooling on the assembly table 21 facilitates subsequent cooperation with the pins, thereby forming a first assembly. Among them, the first assembly mechanism is used to transport the skeleton. As Figure 10As shown, the first assembly mechanism 20 includes a plurality of jaws 25 arranged in the first direction. The plurality of jaws 25 are provided on the top of the assembly table 21. The jaws 25 are used to pick up the skeleton and drive the skeleton to move to the runner tooling.

[0071] Further, before step S1, it also includes:

[0072] Put the skeleton into the first loading tray and perform vibrating feeding on the skeleton.

[0073] Specifically, in the assembly method, the first loading tray is a vibrating loading tray. The first assembly component 22 can pick up the skeleton from the first loading tray and move it to the assembly table 21. The first assembly mechanism 20 also includes a first manipulator 24. The first manipulator 24 can pick up the skeleton and move it to the assembly table 21.

[0074] Further, in step S2, pick up the pin and place it on the pin turntable 222, rotate the pin turntable 222 to a position corresponding to the skeleton on the multi-channel runner tooling, and insert the pin into the skeleton to form the first assembled part, which facilitates the one-to-one matching of the pin and the skeleton located on the multi-channel runner tooling, and then completes the assembly of the first assembled part of the skeleton and the pin.

[0075] Further, before step S2, it also includes:

[0076] Put the skeleton into the second loading tray and perform vibrating feeding on the pins.

[0077] Specifically, in the assembly method, the second loading tray is a vibrating loading tray. The first assembly component 22 can pick up the pins from the second loading tray and move them to the assembly table 21 to realize the assembly with the skeleton.

[0078] Among them, pick up the pin and reach the pin turntable 222. Adopt the first assembly component 22, such as Figure 10 As shown, the first assembly component 22 includes a first moving module 221, a pin turntable 222 and a fixing member 223. The fixing member 223 is arranged on the pin turntable 222. The first moving module 221 is used to move the pin to the fixing member 223. The pin turntable 222 can rotate around its axis to make the pins on the fixing member 223 correspond to the positions of the skeletons on the runner tooling. The fixing member 223 is used to drive the pins to be inserted into the skeletons. The fixing member 223 can receive the pins from the first moving module 221, and then through the rotation of the pin turntable 222, make the position of the fixing member 223 correspond to the position of the skeleton on the assembly table 21, and then move the fixing member 223 towards the skeleton to achieve the purpose of inserting the pins into the skeletons.

[0079] Specifically, as Figure 10As shown, the fixing member 223 has a receiving cavity. The first moving module 221 is used to place the pin in the receiving cavity. One end of the fixing member 223 is arranged close to the center of the pin turntable 222 and is rotatably connected to the pin turntable 222. The other end of the fixing member 223 is located on the side away from the center of the pin turntable 222 and can swing reciprocally relative to the pin turntable 222. In this embodiment, the other end of the fixing member 223 can swing relative to the pin turntable 222, that is, it has a first state and a second state. When the fixing member 223 is in the first state, the fixing member 223 is arranged at an angle with the pin turntable 222. At this time, it is convenient for the first moving module 221 to place the pin into the receiving cavity of the fixing member 223. When the fixing member 223 is in the second state, the fixing member 223 is arranged in a fitting manner with the pin turntable 222. At this time, it is convenient for the fixing member 223 to move towards the skeleton on the assembly table 21, thereby realizing the plugging operation between the skeleton and the pin.

[0080] Further, in step S3, the first assembly is moved to the winding mechanism 30, and an enameled wire is wound around the skeleton by the winding mechanism 30 to form a second assembly, thereby realizing the winding cooperation between the enameled wire and the skeleton. Among them, the first assembly is moved to the winding mechanism 30 by the transfer member 51 of the assembly device. In addition, the enameled wire is wound around the skeleton by the winding mechanism 30, such as Figure 10 and 11 As shown, the winding mechanism 30 includes a bobbin wire 31, a tensioner 32, a winding assembly 33, and a pick-and-place component 34. The winding assembly 33 is arranged on one side of the pick-and-place component 34 along the second direction. The tensioner 32 is arranged on the side of the winding assembly 33 away from the pick-and-place component 34. The bobbin wire 31 is arranged on the side of the tensioner 32 away from the winding assembly 33. The pick-and-place component 34 includes a seat body 342 and a rotating shaft 341. The rotating shaft 341 is rotatably connected to the seat body 342 and is arranged along the first direction. Among them, on opposite ends of the rotating shaft 341 along its radial direction, a loading shaft 3411 and an unloading shaft 3412 are respectively arranged. Clamps are arranged on the sides of the loading shaft 3411 and the unloading shaft 3412 away from the rotating shaft 341. The clamps can clamp or release the first assembly on the transfer member 51.

[0081] Specifically, in this embodiment, such as Figure 11 and 12As shown in the figure, when the transfer member 51 moves to a position corresponding to the winding mechanism 30, the loading shaft 3411 rotates. The fixture of the loading shaft 3411 enters the first assembly from above the first assembly, and then the fixture opens, thereby achieving the fixation of the first assembly. Then, through the rotation of the rotating shaft 341, the loading shaft 3411 is rotated to one side of the winding assembly 33, and the first assembly is sleeved on the rotating seat 331 of the winding assembly 33. The enameled wire of the barrel wire 31 is adjusted in tightness by the tensioner 32 and then conveyed to the winding assembly 33. The winding assembly 33 winds the enameled wire on the outer side of the first assembly while rotating on the rotating seat body 342. After the winding is completed, the unloading shaft 3412 enters the first assembly in the same rotation mode, and realizes opening and clamping, and then can remove the first assembly by rotating, and finally place it on the transfer member 51. The fixture in this embodiment can be two claw bodies that can move relative to each other. Further, the implementation of step S4 is carried out by the third moving module 53 of the assembly device. The third moving module 53 is arranged on the circumferential outer side of the loading turntable 41, and is used to move the first assembly on the transfer member 51 to the working station 411 on the loading turntable 41.

[0082] Further, in step S4, the second assembly is moved to the loading turntable 41 to facilitate other operation processes for the second assembly. The second assembly is moved to the loading turntable 41 by the transfer member 51 of the assembly device.

[0083] Further, in step S5, the magnetic conductor is transported to the loading turntable 41, the second assembly is clamped, and the skeleton of the second assembly is loaded into the magnetic conductor, so as to realize the cooperation between the second assembly and the magnetic conductor.

[0084] Specifically, before step S5, it further includes:

[0085] Put the magnetic conductor into the third loading tray and perform vibrating feeding on the magnetic conductor.

[0086] Specifically, as Figure 13 and 14 shown, the above-mentioned assembly method is implemented by the second manipulator 422 and the third loading tray 421. The second manipulator 422 and the third loading tray 421 both belong to the second assembly component. The second manipulator 422 and the third loading tray 421 are both arranged on the base 10. The second manipulator 422 and the third loading tray 421 are arranged on the circumferential outer side of the loading turntable 41. The third loading tray 421 can load the magnetic conductor to the working station 411. Since the second assembly is already arranged on the working station 411, then the loading turntable 41 is rotated to a position corresponding to the second manipulator 422, and the second manipulator 422 can install the second assembly into the magnetic conductor, thereby realizing the assembly of the magnetic conductor and the second assembly.

[0087] Further, in step S6, the static iron core is clamped to the open end of the magnetic conductor, and the static iron core is fixedly connected to the magnetic conductor to form an oil valve, which facilitates the cooperation between the open ends of the static iron core and the magnetic conductor.

[0088] Specifically, before step S6, it further includes:

[0089] The static iron core is placed in the fourth loading tray, and vibration feeding is performed on the static iron core.

[0090] Specifically, the third assembly component is used in the implementation of the above assembly method. The third assembly component includes a third manipulator 432 and a fourth loading tray 431. Both the third manipulator 432 and the fourth loading tray 431 are arranged on the base 10. The third manipulator 432 can place the static iron core on the fourth loading tray 431 onto the second assembly on the working station 411.

[0091] In some embodiments of the present invention, as Figure 2 shown, after the step of moving the second assembly to the loading turntable 41, it further includes:

[0092] Rotate the working station 411 of the loading turntable 41 to a position corresponding to the first detection component 44 to detect the outer diameter of the enameled wire.

[0093] Specifically, in the above assembly method, after the second assembly moves to the loading turntable 41, it is necessary to detect the outer diameter of the enameled wire outside the skeleton through the first detection component 44, thereby improving the qualification rate of the subsequent oil valve assembly.

[0094] Further, rotating the working station 411 of the loading turntable 41 to a position corresponding to the first detection component 44 to detect the outer diameter of the enameled wire includes:

[0095] Clamp the second assembly on the working station 411 into the detection range of the first detection component 44, and perform photographing detection on the outer diameter of the enameled wire through the first detection component 44.

[0096] Specifically, the above assembly method clamps the second assembly on the working station through a clamping part, as Figure 14As shown, the first detection component 44 includes a third fixing base, a first vision detection component, and a clamping component. Both the clamping component and the first vision detection component are connected to the third fixing base. The clamping component can move towards or away from the feeding turntable 41 and clamp the second assembled component. The first vision detection component is configured to face the second assembled component. In this embodiment, the first vision detection component can be a camera, and the clamping component can be a clamping claw or a suction nozzle or other components for fixing the second assembled component. The clamping component can also move towards or away from the working station 411, that is, lift or lower the second assembled component. After lifting the second assembled component, the second assembled component is photographed by the first detection component 44, and the outer diameter of the second assembled component can be obtained, and then the diameter of the winding of the skeleton external pin can be detected.

[0097] In some embodiments of the present invention, as Figure 2 shown, after the step of detecting the outer diameter of the enameled wire by rotating the working station 411 of the feeding turntable 41 to a position corresponding to the first detection component 44, it further includes:

[0098] Rotate the working station 411 of the feeding turntable 41 to a position corresponding to the welding component 45, and weld the second assembled component and the pin.

[0099] Specifically, in the above assembly method, the welding of the second assembled component and the pin can be realized, and then the firmness performance of the pin can be realized.

[0100] Further, rotating the working station 411 of the feeding turntable 41 to a position corresponding to the welding component 45 and welding the second assembled component and the pin includes:

[0101] Move the welding piece towards the second assembled component and weld the connection between the skeleton and the pin to realize the electrical connection between the enameled wire and the pin.

[0102] Specifically, the above assembly method is implemented based on the welding component. As Figure 14 shown, the second assembly mechanism 40 further includes a welding component 45. The welding component 45 is arranged on the circumferential outer side of the feeding turntable 41. The working station 411 can correspond to the position of the welding component 45. The welding component 45 includes a second fixing base and a welding piece. The welding piece is arranged on the second fixing base and is used to weld the second assembled component and the pin. In this embodiment, the welding piece can be a welding machine. By controlling the moving module of the welding machine, the welding part of the welding machine can be driven to weld the connection between the skeleton and the pin in the second assembled component, improve the firmness performance of the enameled wire and the pin, and make the enameled wire electrically connected to the pin.

[0103] In some embodiments of the present invention, as Figure 3As shown, after the step of welding and connecting the second assembly part and the pin of the second assembly part at the working station 411 of the rotating loading turntable 41 to the position corresponding to the welding assembly 45, the following steps are further included:

[0104] Rotate the working station 411 of the rotating loading turntable 41 to the position corresponding to the second detection assembly 46, and detect the conductivity of the second assembly part and the pin of the second assembly part.

[0105] Specifically, in this embodiment, the above assembly method can detect the conductivity of the second assembly part and the pin, which is convenient for ensuring the yield rate of the subsequent oil valve assembly.

[0106] Further, rotating the working station 411 of the rotating loading turntable 41 to the position corresponding to the second detection assembly 46 and detecting the conductivity of the second assembly part and the pin of the second assembly part includes:

[0107] Move the conductive test piece towards the second assembly part and conduct a conduction test on the pin.

[0108] Specifically, as Figure 14 shown, the second assembly mechanism 40 further includes a second detection assembly 46. The second detection assembly 46 is arranged on the circumferential outer side of the loading turntable 41. The working station 411 can correspond to the position of the second detection assembly 46. The second detection assembly 46 includes a fourth fixing seat and a conductive test piece. The conductive test piece is arranged on the fourth fixing seat and can move towards or away from the loading turntable 41 to conduct a conductivity test on the pin of the second assembly part. In this embodiment, the conductive test piece is electrically connected and can move towards the second assembly part on the working station 411 to be electrically connected to the pin on the second assembly part to detect the conduction test of the pin.

[0109] In some embodiments of the present invention, as Figure 4 shown, after the step of rotating the working station 411 of the rotating loading turntable 41 to the position corresponding to the second detection assembly 46 and detecting the conductivity of the second assembly part and the pin of the second assembly part, the following steps are further included:

[0110] Rotate the working station 411 of the rotating loading turntable 41 to the position corresponding to the bending assembly 47, and bend the pin of the second assembly part.

[0111] Further, rotating the working station 411 of the rotating loading turntable 41 to the position corresponding to the bending assembly 47 and bending the pin of the second assembly part includes:

[0112] Lift the second assembly part on the working station 411, move towards the second assembly part through the bending piece 473, and bend the pin of the second assembly part.

[0113] Further, asFigure 15 As shown, the second assembly mechanism 40 further includes a bending assembly 47. The working station 411 can correspond to the position of the bending assembly 47. The bending assembly 47 is arranged on the circumferential outer side of the loading turntable 41 and is used for bending the pins of the second assembly. In this embodiment, when the working station 411 rotates to correspond to the position of the bending assembly 47, the lifting member 472 can pass through the through hole and lift the second assembly on the working station 411. Then, the bending member 473 bends the pins of the second assembly to achieve the bending purpose.

The lifting member 472 can pass through the through hole and lift the second assembly on the working station 411. The bending member 473 is used for bending the pins of the second assembly. In this embodiment, when the working station 411 rotates to correspond to the position of the bending assembly 47, the lifting member 472 can pass through the through hole and lift the second assembly on the working station 411.

The support member 474 is connected to the first fixed seat 471 and can move towards or away from the loading turntable 41. The support member 474 is used to abut against the bottom surface of the pins of the second assembly. In this embodiment, the support member 474 can abut and support under the lifted pins of the second assembly, facilitating the bending member 4732 to bend the specific part of the pins. The pins abutting against the support member 474 will not be bent, improving the reliability.

Specifically, in this embodiment, the feeding turntable 41 is rotated to a position corresponding to the bending component 47, and after the pins are bent, a photographing camera is used to detect the appearance and dimensions of the bending part 4732, which can avoid the problem of poor oil valve performance caused by poor bending.
