[0033] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] like Figure 1-5 As shown, a fuel injector valve core vibratory feeding device includes: a fixed base 40, a feeding mechanism 10, a vibratory plate 20, and a screening mechanism 30.

[0035] Vibratory plate 20 includes vibratory plate cavity 210; vibratory plate 20 is configured to supply fuel injector valve core 1 in vibratory plate cavity 210 to screening mechanism 30 by means of its vibration.

[0036] The feeding mechanism 10 includes a feeding box 101 with a storage chamber 102; the feeding mechanism 10 is configured to supply the fuel injector valve core 1 temporarily stored in the storage chamber 102 to the vibrating plate cavity 210 by means of vibration.

[0037] The screening mechanism 30 includes a conveying module 31 connected to the output end of the feeding mechanism 10 and an adjustment module 32 connected to the output end of the conveying module 31. The screening mechanism 30 is configured to transport the fuel injector valve core 1 supplied by the feeding mechanism 10 to the adjustment module 32 via the conveying module 31 by means of vibration, and adjust the fuel injector valve core 1 to the same posture during the transportation process. The vibratory plate 20 is fixedly connected to the fixed base 40 via the vibratory plate support 70.

[0038] The fuel injector valve core 1 includes a short needle body 13, a cylindrical body 11, and a long needle body 12 that are fixedly connected in sequence; the minimum diameter of the cylindrical body 11 is greater than the maximum diameter of the short needle body 13 and the long needle body 12.

[0039] Furthermore, the fuel injector valve core vibration feeding device also includes a first fixed base 90, a second fixed base 50, a first direction control mechanism 80 for controlling the vibration direction of the feeding mechanism 10, and a second direction control mechanism 60 for controlling the vibration direction of the screening mechanism 30. The feeding mechanism 10 is fixedly connected to the first direction control mechanism 80; the first direction control mechanism 80 is fixedly connected to the fixed base 40 via the first fixed base 90; the screening mechanism 30 is fixedly connected to the second direction control mechanism 60; and the second direction control mechanism 60 is fixedly connected to the fixed base 40 via the second fixed base 50.

[0040] It should be noted that the vibratory feeder 20 adopts the existing mature power and direction control schemes of vibratory feeders, such as the electromagnet body, armature body and spring plate scheme disclosed in the patent in the background technology. Such technical solutions are mature existing technologies and will not be described in detail here.

[0041] Similarly, both the first direction control mechanism 80 and the second direction control mechanism 60 adopt the same direction control scheme as existing vibratory feeders, namely, using inclined spring plates for direction control. Specifically, the feeding mechanism 10 is connected to the first fixed seat 90 using inclined spring plates, and the screening mechanism 30 is connected to the second fixed seat 50 using inclined spring plates. Since existing vibratory feeders also use inclined spring plates for direction control, which is a mature existing technology, it will not be described further here.

[0042] In this embodiment, the screening mechanism 30 is fixedly connected to the vibrating plate 20, and its vibration is driven by the power provided by the vibrating plate 20. The feeding mechanism 10 is also fixedly connected to the vibrating plate 20, and its vibration is driven by the power provided by the vibrating plate 20. This scheme can realize the linkage of the feeding mechanism 10, the vibrating plate 20 and the screening mechanism 30, and is energy-saving and environmentally friendly. However, it should be noted that it is necessary to increase the power of the vibrating plate 20 when necessary to ensure that the feeding mechanism 10, the vibrating plate 20 and the screening mechanism 30 have sufficient power during the linkage process.

[0043] In addition, corresponding power devices can be installed in the first direction control mechanism 80 and the second direction control mechanism 60 to realize independent vibration of the feeding mechanism 10 and the screening mechanism 30.

[0044] In this embodiment, the conveying module 31 includes a conveying block 312 and a conveying groove 311 disposed on the conveying block 312. The adjustment module 32 includes an adjustment block 324, the adjustment block 324 having a reversing cavity 325 capable of accommodating the long needle body portion 12. The adjustment block 324 includes a supporting portion 323 and an inclined cone portion 322. The adjustment module 32 also includes a reversing groove 321 penetrating the inclined cone portion 322, the reversing groove 321 communicating vertically with the reversing cavity 325. The width of the reversing groove 321 is smaller than the diameter of the cylindrical portion 11 and larger than the diameter of the long needle body portion 12. The depth of the reversing cavity 325 is greater than the length of the long needle body portion 12.

[0045] The width of the inclined cone 322 is smaller than the width of the conveying groove 311. Fuel injector valve cores 1 that are not arranged as required in the conveying groove 311 can fall out through the gap between the conveying groove 311 and the inclined cone 322. Fuel injector valve cores 1 that are arranged as required can enter the reversing groove 321 under vibration.

[0046] In addition, the adjusting block 324 also includes a horizontally positioned bearing surface 326 located at the upper end of the inclined cone portion 322, and the bearing surface 326 is not higher than the lowest surface of the conveying groove 311. The horizontally positioned bearing surface 326 can effectively support the column portion 11, ensuring the smooth movement of the fuel injector valve core 1.

[0047] In another embodiment of this utility model, the fuel injector valve core vibratory feeding device further includes a collection hopper 100 for collecting the fuel injector valve cores 1 screened out by the screening mechanism 30. The collection hopper 100 includes an upward-opening collection cavity, which is located below the screening mechanism 30.

[0048] Furthermore, the vibratory feeder 20 also includes a return port 220. The receiving cavity and the vibratory feeder body cavity 210 are connected through the return port 220, so that the fuel injector valve cores collected in the receiving hopper 100 are returned to the vibratory feeder body cavity 210 for a new round of screening and feeding.

[0049] In another embodiment of this utility model, a first inclined surface 110, a second inclined surface 120, and a third inclined surface 130 are also provided in the receiving cavity; the third inclined surface 130 is disposed between the first inclined surface 110 and the second inclined surface 120; the first inclined surface 110 and the second inclined surface 120 are both connected to the third inclined surface 130; the included angle between the first inclined surface 110 and the third inclined surface 130 is an acute angle; the included angle between the second inclined surface 120 and the third inclined surface 130 is an acute angle; the included angle between the third inclined surface 130 and the horizontal plane is an acute angle, and the acute angle is located opposite to the return port 220. By setting the first inclined surface 110, the second inclined surface 120, and the third inclined surface 130, the area near the return port 220 in the receiving cavity is the lowest area, which facilitates the return of the fuel injector valve core 1 to the vibrating disc cavity 210 under the action of gravity, preventing material accumulation.

[0050] Furthermore, the feeding mechanism 10 also includes a feeding plate 104, which is fixedly connected to the feeding box 101, and the discharge end of the feeding plate 104 is located above the vibrating plate cavity 210; there is a feeding port 103 through which the fuel injector valve core 1 passes between the feeding end of the feeding plate 104 and the storage cavity 102.

[0051] In use, the fuel injector valve core 1 is stored in the feed box 101 and enters the vibratory feeder cavity 210 through the feed port 103 and feed plate 104 under vibration. Relying on the vibration and straightening action of the vibratory feeder 20, the initially straightened fuel injector valve core 1 enters the conveying groove 311 of the conveying module 31 and moves towards the adjustment module 32 under vibration. When the fuel injector valve core 1 is transported to the position between the conveying module 31 and the adjustment module 32, because the width of the conveying groove 311 is greater than the width of the inclined cone 322, the inclined fuel injector valve core 1 enters the outside of the inclined cone 322 and falls off with further movement. Since the conveying groove 311 and the reversing groove 321 are on a straight line, the fuel injector valve core 1, arranged as required, can enter the reversing groove 321 under vibration. Under the influence of gravity, the long needle body 12 enters the reversing cavity 325. Since the diameter of the cylindrical part 11 is larger than that of the reversing groove 321, it can be supported by the bearing surface 326. Under the influence of vibration, the fuel injector valve core 1 moves further along the reversing groove 321 until it reaches the preset detection position or the corresponding bearing device.
