Description

Technical Field

[0001] This invention relates to the field of air valve installation equipment technology, and more particularly to an air valve vertical installation production line. Background Technology

[0002] An air valve generally includes a coil frame, a moving iron core, a stationary iron core, and a yoke. A coil is wound on the coil frame. Additionally, a spring is installed between the moving and stationary iron cores. For the structure and exploded view of the air valve, please refer to [link to relevant diagrams]. Figure 1 and Figure 2 Currently, the assembly of air valves has been largely automated. Because the moving iron core and spring need to be sequentially assembled into the inner cavity of the coil frame, and then the cavity opening is sealed by the stationary iron core, existing automated air valve assembly methods involve laying the coil frame flat (with the inner cavity opening facing horizontally) before assembling other components. This means that before the stationary iron core is assembled, the moving iron core and spring also fall out of the inner cavity. However, the assembly mechanisms for these components—spring, moving iron core, and stationary iron core—require horizontally pushing cylinders to push them into the coil frame, resulting in a large space requirement for the assembly mechanism and a large footprint for the entire production line, which is inconvenient for transportation and on-site setup. Summary of the Invention

[0003] The purpose of this invention is to provide a vertical installation production line for air valves, which has a compact structure, small footprint, and high production efficiency.

[0006] The circulation device includes a circulation power mechanism and several clamping mechanisms for limiting the coil frame. The circulation power mechanism drives each clamping mechanism to sequentially pass through the coil frame assembly station, the moving iron core assembly station, the stationary iron core assembly station, the yoke assembly station, and the discharge station and circulates. The clamping mechanism is equipped with a magnetic suction component for adsorbing the moving iron core.

[0007] A coil frame assembly device, located at the coil frame assembly station, is used to vertically place the coil frame at the coil frame assembly station.

[0009] A stationary iron core assembly device is located at the stationary iron core assembly station and is used to drive the stationary iron core to be inserted into the coil frame located at the stationary iron core assembly station from bottom to top.

[0010] A yoke assembly device, located at the yoke assembly station, is used to drive the yoke to insert into the coil frame and stationary iron core located at the yoke assembly station.

[0011] The controller connects the power mechanism, clamping mechanism, coil frame assembly device, moving iron core assembly device, stationary iron core assembly device, and yoke assembly device of the cycle.

The yoke positioning assembly includes a fixed component and a rotating component. The rotating component is rotatably connected to the fixed component. The rotary positioning module drives the rotating component to rotate. When the horizontal positioning module and the rotary positioning module are in their initial state, the rotating component cooperates with the outlet of the yoke supply mechanism to complete the position transition of the yoke. When the horizontal positioning module is activated, the fixed component blocks the yoke supply mechanism from discharging material.

[0020] Preferably, both the moving core mounting mechanism and the stationary core mounting mechanism include a core horizontal moving module, a core lifting moving module, a core mounting base, and a core lifting assembly. The core horizontal moving module drives the core lifting module to move horizontally, and the core lifting module drives the core mounting base and the core lifting assembly to move vertically. The core mounting base is provided with a core positioning hole. The core lifting assembly includes a lifting cylinder and a lifting rod.

[0023] Preferably, the coil frame mounting mechanism, yoke mounting mechanism, and unloading mechanism each include a mounting frame, a rotary motor, a swing arm, a slide module, and a gripping assembly. The base of the rotary motor is locked onto the mounting frame. One end of the swing arm is connected to the output shaft of the rotary motor, and the other end of the swing arm has a sliding hole. The slide module includes a base and a sliding seat. The base is rotatably connected to the mounting frame, and the sliding seat is slidably connected to the base. One end of the sliding seat has a guide post and a pulley. One end of the guide post is connected to the sliding seat, and the other end of the guide post passes through the sliding hole and is connected to the pulley. The mounting frame has a groove that mates with the pulley. The gripping assembly is located at the end of the sliding seat away from the pulley. The rotary motor, swing arm, slide module, and groove work together to drive the gripping assembly to reciprocate upward movement, 90° rotation, and horizontal pushing.

[0024] The gripping component corresponding to the coil frame mounting mechanism is a clamping cylinder;

[0025] The gripping components corresponding to the yoke mounting mechanism and the unloading mechanism each include a pushing cylinder, a pushing block, and a magnetic suction seat for adsorbing the yoke.

[0027] Preferably, the frame is further provided with a moving iron core detection station, which is located between the moving iron core assembly station and the stationary iron core assembly station; the moving iron core detection station is provided with a moving iron core detection sensor for detecting whether the moving iron core is assembled in place, and the moving iron core detection sensor is connected to the controller.

[0028] The stationary iron core assembly station is also equipped with a spring detection sensor for detecting whether a spring is assembled on the stationary iron core, and the spring detection sensor is connected to a controller.

[0029] The present invention has the following beneficial effects:

[0030] This invention automates the installation of air valves by vertically placing the coil frame at the coil frame assembly station and clamping it in place using a clamping mechanism. The clamping mechanism then moves to the next station, where the moving iron core is pushed upwards into the inner cavity of the coil frame. The moving iron core is attracted by a magnetic component on the clamping mechanism to prevent it from falling out. The clamping mechanism then moves to the stationary iron core assembly station, where a spring-loaded stationary iron core is pushed upwards and inserted into the inner cavity of the coil frame. Subsequently, the clamping mechanism moves to the yoke assembly station to complete the yoke installation. Finally, the assembled air valve is unloaded at the discharge station. This invention requires only an additional device to assemble the spring into the stationary iron core to achieve fully automated air valve installation, resulting in high efficiency. The vertical installation of the moving and stationary iron cores onto the coil frame effectively reduces the footprint of the moving and stationary iron core assembly devices. Furthermore, the cyclic power mechanism drives each clamping mechanism sequentially through each station, resulting in a more compact overall structure with a smaller footprint, facilitating production site layout and transportation.

[0063] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0064] like Figures 3-22 As shown, this invention discloses a vertically installed production line for air valves 10, comprising: a controller, a frame 20, a circulation device 30, a coil frame assembly device, a moving iron core assembly device 60, a cleaning device 50, a stationary iron core assembly device 70, a yoke assembly device 80, and a unloading device. The controller is a PLC.

[0065] The frame 20 has a series of stations arranged sequentially around its circumference: coil bobbin assembly station, cleaning station, moving iron core assembly station, moving iron core inspection station, stationary iron core assembly station, yoke assembly station, and discharge station. The circulation device 30 includes a circulation power mechanism and several clamping mechanisms 32 for limiting the coil bobbin 11. Preferably, the number of clamping mechanisms 32 is not less than the total number of the aforementioned stations. The circulation power mechanism is preferably an electric turntable 31, which is connected to a controller. The clamping mechanisms 32 are evenly distributed around the outer edge of the electric turntable 31. The electric turntable 31 drives each clamping mechanism 32 to sequentially pass through the coil bobbin assembly station, cleaning station, moving iron core assembly station, moving iron core inspection station, stationary iron core assembly station, yoke assembly station, and discharge station, thus circulating the coil bobbin assembly station.

[0066] The clamping mechanism 32 includes a first clamping cylinder 321, a magnetic suction cylinder 322, and a support base 323. The first clamping cylinder 321 and the magnetic suction cylinder 322 are connected to a controller. The base of the first clamping cylinder 321 is locked onto the surface of the electric turntable 31. Each of the two clamping arms of the first clamping cylinder 321 is provided with a clamping block 324, and the clamping block 324 extends beyond the outer edge of the electric turntable 31, that is, the clamping block 324 is suspended relative to the electric turntable 31 to ensure that the moving iron core 12 and the stationary iron core 13 can be assembled. The support base 323 is locked onto the electric turntable 31 and is placed between the two clamping arms. The support base 323 is used to provide horizontal support for the coil frame 11 when the yoke 15 is installed. The base of the magnetic cylinder 322 is mounted on the electric turntable 31, and the magnetic cylinder 322 is located above the clamping block 324. A magnetic element 325, such as a permanent magnet, is provided at the end of the push rod of the magnetic cylinder 322. The magnetic cylinder 322 can drive the magnetic element 325 to move up and down relative to the clamping block 324. A clearance hole 3251 is provided at the bottom of the magnetic element 325 to avoid the coil frame 11. The clearance hole 3251 allows the magnetic element 325 to move downwards as much as possible, facilitating stable attraction of the moving iron core 12. Furthermore, when the magnetic element 325 moves downwards, it also provides vertical support for the clamped and fixed coil frame 11.

[0067] A coil frame assembly device is installed at the coil frame assembly station. It is used to vertically place the coil frame 11 at the station so that the clamping mechanism 32 located there can vertically clamp and fix the coil frame 11. Specifically, the coil frame assembly device includes a coil frame supply mechanism, a first conveying mechanism 41, a coil frame feeding mechanism 42, and a coil frame mounting mechanism 43. The coil frame supply mechanism continuously supplies the coil frame 11. A vibratory feeder is used for the coil frame supply mechanism; vibratory feeders are a mature existing technology and will not be described in detail here. The coil frame supply mechanism is connected to a controller.

[0068] The first conveying mechanism 41 is used to convey coil bobbins 11 at equal intervals so that they can be grasped by the coil bobbin mounting mechanism 43. The first conveying mechanism 41 includes a belt conveyor assembly 411 and several product positioning seats 412. The product positioning seats 412 are evenly distributed on the conveying surface of the belt conveyor assembly 411 and are used to position and place the coil bobbins 11. The belt conveyor assembly 411 is prior art and typically includes a belt, two pulleys, and a motor. The belt connects the two pulleys and is taut. The motor drives one of the pulleys to rotate, and the product positioning seats 412 are locked to the belt. The motor corresponding to the belt conveyor assembly 411 is connected to a controller. The arrangement of the first conveying mechanism 41 allows the coil bobbin supply mechanism to be located relatively far from the electric turntable 31, which is beneficial for the overall structural layout.

[0069] The coil bobbin feeding mechanism 42 is used to place the coil bobbin 11 from the coil bobbin supply mechanism onto the product positioning seat 412 of the first conveying mechanism 41. It includes a first feeding horizontal moving module 421, a first feeding lifting module 422, and at least one first feeding clamping cylinder 423. The first feeding horizontal moving module 421 drives the first feeding lifting module 422 to move horizontally, and the first feeding lifting module 422 drives the first feeding clamping cylinder 423 to lift. Both the first feeding horizontal moving module 421 and the first feeding lifting module 422 are linear moving modules based on motors or cylinders, which is existing technology. The first feeding horizontal moving module 421 and the first feeding lifting module 422 are connected to a controller. In addition to the motor or cylinder, the linear moving module typically includes a slide rail, a slider, and a screw (only included when the power component is a motor). The slide rail is fixedly installed, the slider is slidably connected to the slide rail, and the driven moving component is mounted on the slider. If the power component is a cylinder, the cylinder directly pushes the slider to slide relative to the slide rail. If the power component is a motor, the motor drives the screw to rotate. The screw is set parallel to the slide rail, and both ends of the screw are rotatably connected to a turntable, which is fixedly set. Multiple sets of the first feeding clamping cylinder 423 can be set to simultaneously clamp multiple coil bobbins 11. In this case, four sets are set. The first feeding clamping cylinder 423 is connected to the controller.

[0070] The coil frame mounting mechanism 43 is used to grip and place the coil frame 11 on the first conveying mechanism 41 to the coil frame assembly station. It includes a first mounting frame 431, a first rotary motor 432, a first swing arm 433, a first slide module, and a first gripping assembly 435. In this case, the first gripping assembly 435 is a clamping cylinder. The first rotary motor 432 and the first gripping assembly 435 are connected to a controller. The base of the first rotary motor 432 is locked to the first mounting frame 431. One end of the first swing arm 433 is connected to the output shaft of the first rotary motor 432, and the other end of the first swing arm 433 is provided with a sliding hole 4331 (elongated hole). The first slide module includes a base 4341 and a sliding seat 4342. The base 4341 is rotatably connected to the first mounting frame 431, and the sliding seat 4342 is slidably connected to the base 4341. One end of the sliding seat 4342 is provided with a guide post 4343 and a pulley 4344. One end of the guide post 4343 is connected to the sliding seat 4342, and the other end of the guide post 4343 passes through the sliding hole 4331 and is connected to the pulley 4344. The first mounting bracket 431 is provided with a groove 4311 that mates with the pulley 4344. The first gripping component 435 is located at the end of the sliding seat 4342 away from the pulley 4344. The first rotary motor 432, the first swing arm 433, the first slide module, and the groove 4311 work together to drive the first gripping component 435 to reciprocate upward movement, 90° rotation, and horizontal pushing. Under normal conditions, the first gripping component 435 does not obstruct the coil bobbin 11 from being conveyed on the first conveying mechanism 41. When the coil bobbin 11 is conveyed to the area below the coil bobbin mounting mechanism 43, the first gripping component 435 moves downward and grips the coil bobbin 11 directly below it. Then, the first gripping component 435 moves upward, rotates 90°, and pushes horizontally, so that the coil bobbin 11 held by the first gripping component 435 is sent to the coil bobbin assembly station. The clamping mechanism 32 located at the coil bobbin assembly station can then clamp and fix the coil bobbin 11 (at this time, the magnetic suction component 325 is in the retracted state). Afterward, the first gripping component 435 releases and returns to its initial position, waiting for the next gripping operation. The power source for the movement of the first gripping component 435 is only a first rotary motor 432. Compared with the conventional method of combining a motor with a cylinder, this allows the structure of the coil bobbin mounting mechanism 43 to be more streamlined, lower in cost, and more energy-efficient.

[0071] A cleaning device 50 for blowing air into the inner cavity of the coil frame 11 is provided at the cleaning station. This device includes a cleaning lifting module 51 and an air nozzle assembly 52. ​​The cleaning lifting module 51 drives the air nozzle assembly 52 to rise and fall. In this case, the cleaning lifting module 51 can be a cylinder, or a cylinder-based linear motion module can be used. The cleaning lifting module 51 is connected to a controller. The air nozzle assembly 52 includes an air nozzle and a valve. The air nozzle is connected to an external air supply pipe, and the valve is connected to the controller. When the clamping mechanism 32 holding the coil frame 11 moves to the cleaning station, the cleaning lifting module 51 raises the air nozzle assembly 52, blowing air into the inner cavity of the coil frame 11 through the air nozzle, thus completing the cleaning of the inner cavity of the coil frame 11.

[0072] A moving iron core assembly device 60 is installed at the moving iron core assembly station to drive the moving iron core 12 to be inserted from bottom to top into the coil frame 11 located at the moving iron core assembly station. The moving iron core assembly device 60 includes a moving iron core supply mechanism 61, a moving iron core mounting mechanism 62, and a moving iron core feeding mechanism 63. The moving iron core supply mechanism 61 is used to supply moving iron cores 12 in batches. In this case, the moving iron core supply mechanism 61 adopts the form of a tray supply mechanism. Specifically, the tray supply mechanism includes a tray linear movement module 611, a tray mounting base 612, and at least one tray body 613. The tray linear movement module 611 is a motor-based linear movement module, which is prior art. Refer to the first feeding horizontal movement module 421. The tray linear movement module 611 is connected to the controller. The tray linear movement module 611 drives the tray mounting base 612 to move relative to the moving iron core feeding mechanism 63. The tray body 613 is detachably connected to the tray mounting base 612, for example, by plugging it in, to facilitate replacement of the tray body 613. Several product placement stations 6131 are arrayed on the tray body 613 for placing the moving iron cores 12. Alternatively, a vibratory feeder can be used as the tray supply mechanism. After the moving iron core feeding mechanism 63 has grasped an entire row of moving iron cores 12 located below it, the tray body 613 is pushed a distance of one column, placing the next row of moving iron cores 12 below the moving iron core feeding mechanism 63.

[0073] The moving iron core mounting mechanism 62 is used to assemble the moving iron core 12 onto the coil frame 11 located at the moving iron core assembly station. The moving iron core mounting mechanism 62 includes a first iron core horizontal moving module 621, a first iron core lifting module 624, a first iron core mounting base 622, and a first iron core lifting assembly. Both the first iron core horizontal moving module 621 and the first iron core lifting module 624 are cylinder-based linear moving modules, which will not be described in detail. The first iron core horizontal moving module 621 and the first iron core lifting module 624 are connected to a controller. The first iron core horizontal moving module 621 drives the first iron core lifting module 624 to move horizontally relative to the moving iron core assembly station. The first iron core lifting module 624 drives the first iron core mounting base 622 and the first iron core lifting assembly to move up and down synchronously. A first iron core positioning hole 6221 is provided on the first iron core mounting base 622 for positioning and placing the moving iron core 12. The first core lifting assembly includes a first lifting cylinder 6231 and a first lifting rod 6232. The first lifting cylinder 6231 is connected to a controller. The first lifting rod 6232 is adapted to the first core positioning hole 6221, with one end of the first lifting rod 6232 inserted into the first core positioning hole 6221 and the other end connected to the first lifting cylinder 6231. The first lifting cylinder 6231 drives the first lifting rod 6232 to slide relative to the first core positioning hole 6221. When the moving iron core feeding mechanism 63 places the moving iron core 12 into the first iron core positioning hole 6221, the moving iron core 12 is supported by the first lifting rod 6232 and will not fall out from the lower end of the first iron core positioning hole 6221. When the first iron core mounting base 622 is pushed to the moving iron core assembly station by the first iron core horizontal moving module 621, the first iron core lifting module 624 lifts the first iron core mounting base 622, so that the first iron core positioning hole 6221 is closer to or even connected to the inner cavity of the coil frame 11. Then the first lifting rod 6232 is lifted, pushing the moving iron core 12 into the inner cavity of the coil frame 11. At the same time, the magnetic suction component 325 moves down, so that the moving iron core 12 is attracted and fixed. After that, the first lifting rod 6232 can be withdrawn.

[0074] The moving iron core feeding mechanism 63 is used to place the moving iron core 12 on the moving iron core supply mechanism 61 into the first iron core positioning hole 6221 of the moving iron core mounting mechanism 62. The structure of the moving iron core feeding mechanism 63 is basically the same as that of the coil frame feeding mechanism 42. In order to distinguish it from the coil frame feeding mechanism 42, the moving iron core feeding mechanism 63 includes a second feeding horizontal moving module 631, a second feeding lifting module 632, and a second feeding clamping cylinder 633. The cooperation relationship between the second feeding horizontal moving module 631, the second feeding lifting module 632, and the second feeding clamping cylinder 633 is the same as that between the first feeding horizontal moving module 421, the first feeding lifting module 422, and the first feeding clamping cylinder 423, which will not be described again. Specifically, only one second feeding clamping cylinder 633 is provided, and the shape of the clamping arm of the second feeding clamping cylinder 633 is adapted to clamp the moving iron core 12 in order to better clamp the moving iron core 12.

[0075] A moving iron core detection sensor is installed at the moving iron core inspection station to detect whether the moving iron core 12 is properly assembled. The moving iron core detection sensor is connected to the controller. A distance measuring sensor can be selected as the moving iron core detection sensor.

[0076] A stationary iron core assembly device 70 is installed at the stationary iron core assembly station to drive the stationary iron core 13 to be inserted into the coil frame 11 located at the stationary iron core assembly station from bottom to top. The stationary iron core assembly device 70 includes a stationary iron core supply mechanism, a stationary iron core mounting mechanism 71, and a stationary iron core feeding mechanism 72. The stationary iron core supply mechanism is used to continuously supply the stationary iron core 13. It can be a tray supply mechanism. In this case, the supplied stationary iron core 13 needs to be equipped with a spring 14. The stationary iron core 13 is generally provided with mounting holes 131 to install the spring 14, ensuring that the mounting holes 131 face upwards. Under normal circumstances, the spring 14 will not fall off. The assembly of the spring 14 and the stationary iron core 13 can be done manually and then stacked on a tray, or a dedicated spring 14 and stationary iron core 13 assembly device can be designed, and then stacked on a tray.

[0077] The stationary core mounting mechanism 71 is used to assemble the stationary core 13 onto the coil frame 11 located at the stationary core assembly station. The structure of the stationary core mounting mechanism 71 is basically the same as that of the moving core mounting mechanism 62. For ease of distinction, the stationary core mounting mechanism 71 includes a second core horizontal moving module 711, a second core lifting module 714, a second core mounting base 712, and a second core lifting assembly 713. The cooperation relationship between the second core horizontal moving module 711, the second core lifting module 714, the second core mounting base 712, and the second core lifting assembly 713 is the same as that between the first core horizontal moving module 621, the first core lifting module 624, the first core mounting base 622, and the first core lifting assembly, and will not be described again.

[0078] The stationary iron core feeding mechanism 72 is used to place the stationary iron core 13 from the stationary iron core supply mechanism onto the stationary iron core mounting mechanism 71. The structure of the stationary iron core feeding mechanism 72 is basically the same as that of the moving iron core feeding mechanism 63. For easy distinction, the stationary iron core feeding mechanism 72 includes a third feeding horizontal moving module 721, a third feeding lifting module 722, and a third feeding clamping cylinder 723. The cooperation relationship between the third feeding horizontal moving module 721, the third feeding lifting module 722, and the third feeding clamping cylinder 723 is the same as that between the second feeding horizontal moving module 631, the second feeding lifting module 632, and the second feeding clamping cylinder 633, which will not be described again.

[0079] Specifically, after the stationary iron core 13 is fed from the stationary iron core feeding mechanism 72 to the stationary iron core mounting mechanism 71, the spring detection sensor 73 detects whether the stationary iron core 13 on the stationary iron core mounting mechanism 71 is equipped with a spring 14. The spring detection sensor 73 can be a photoelectric switch, and the spring detection sensor 73 is connected to the controller.

[0080] A yoke assembly device 80 is installed at the yoke assembly station to drive the yoke 15 to insert into the coil frame 11 and the stationary iron core 13 located at the yoke assembly station. The yoke assembly device 80 includes a yoke supply mechanism 81, a yoke positioning mechanism 82 for positioning the yoke 15, and a yoke mounting mechanism 83. The yoke supply mechanism 81 is used to supply the yoke 15. In this case, the yoke supply mechanism 81 is a vibratory feeder connected to a controller.

[0081] The yoke positioning mechanism 82 is used to distribute and position the yoke 15 output from the yoke supply mechanism 81, so that the yoke 15 can be gripped. The yoke positioning mechanism 82 includes a horizontal positioning module 821, a rotary positioning module 822, and a yoke 15 positioning assembly. The horizontal positioning module 821 is a cylinder-based linear movement module, and the rotary positioning module 822 is a rotary module based on a rotary cylinder or motor; both are existing technologies and will not be described further. Both the horizontal positioning module 821 and the rotary positioning module 822 are connected to a controller. The horizontal movement module drives the rotary positioning module 822 and the yoke 15 positioning assembly to move horizontally synchronously. The yoke 15 positioning assembly includes a fixed member 8231 and a rotating member 8232, which is rotatably connected relative to the fixed member 8231. The rotary positioning module 822 drives the yoke 15 positioning member to rotate. When the positioning horizontal moving module 821 and the positioning rotating module 822 are in their initial states, the rotating component 8232 engages with the outlet of the yoke supply mechanism 81, allowing the yoke 15 to be conveyed onto the rotating component 8232, completing the position transition of the yoke 15. When the positioning horizontal moving module 821 is activated, the fixing component 8231 moves laterally along the outlet of the yoke supply mechanism 81 for a certain distance, thereby blocking the yoke supply mechanism 81 from discharging material. Subsequently, the positioning rotating module 822 is activated, adjusting the yoke 15 on the rotating component 8232 to an angle suitable for the gripping and installation of the yoke mounting mechanism 83.

[0082] The yoke mounting mechanism 83 is used to grip the yoke 15 on the yoke positioning mechanism 82 and connect it to the coil frame 11 and the stationary iron core 13. The structure of the yoke mounting mechanism 83 is basically the same as that of the coil frame mounting mechanism 43. For easy distinction, the yoke mounting mechanism 83 includes a second mounting frame 831, a second rotary motor 832, a second swing arm 833, a second slide module 834, and a second gripping assembly. The cooperation relationship between the second mounting frame 831, the second rotary motor 832, the second swing arm 833, the second slide module 834, and the second gripping assembly is the same as the cooperation relationship between the first mounting frame 431, the first rotary motor 432, the first swing arm 433, the first slide module, and the first gripping assembly 435. The second gripping assembly is modified. Specifically, the second gripping assembly includes a pusher cylinder 8351, a pusher block 8352, and a magnetic suction seat 8353 for adsorbing the yoke 15. The pusher cylinder 8351 is connected to a controller. A through slide rail 8354 is provided on the magnetic base 8353, and a pusher block 8352 is slidably connected in the slide rail. The pusher cylinder 8351 drives the pusher block 8352 to slide relative to the slide rail 8354, and the pusher block 8352 can extend out of the magnetic base 8353. When it is necessary to grasp the yoke 15, the pusher block 8352 does not extend out of the slide rail 8354, and the magnetic base 8353 adsorbs the yoke 15 on the rotating part 8232. In order to prevent the yoke 15 from changing its posture during movement, the shape of the magnetic base 8353 is adjusted to match the shape of the yoke 15. After the yoke 15 is adsorbed and grasped by the magnetic base 8353, the magnetic base 8353 is displaced to the yoke assembly station, and then the pusher block 8352 extends to insert the yoke 15 into the corresponding slots of the coil frame 11 and the stationary iron core 13, completing the assembly of the air valve 10.

[0083] The unloading device is located at the discharge station and includes a second conveying mechanism 91 for conveying the air valve 10 and an unloading mechanism 92 for grabbing the air valve 10 located at the discharge station and placing it onto the second conveying mechanism 91. The second conveying mechanism 91 is the same as the first conveying mechanism 41, and the unloading mechanism 92 is the same as the yoke mounting mechanism 83, which will not be described again. After the clamping mechanism 32 moves to the discharge station, the magnetic suction component 325 retracts, and the magnetic suction seat 8353 corresponding to the unloading mechanism 92 attracts the yoke 15 of the air valve 10. After the clamping mechanism 32 is released, the air valve 10 is grabbed by the magnetic suction seat 8353 corresponding to the unloading mechanism 92 and then placed onto the product positioning seat 412 corresponding to the second conveying mechanism 91.

[0084] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
