[0032] In order to further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail as follows:

[0033] Please refer to Figures 1 to 4 , this embodiment provides a keyboard scissor foot arranging device for a notebook computer, including a support component 1, a screening and arranging component 2 and a vibration component 3;

[0034] The support component 1 includes a first support plate 11;

[0035] The screening and arranging component 2 includes a second support plate 21 and a material tray 22;

[0036] The second support plate 21 is arranged above the first support plate 11;

[0037] The material tray 22 is fixedly arranged on the second support plate 21. The upper end of the material tray 22 is provided with a screening area 221 and an arranging area 222 in parallel. A plurality of arranging grooves 223 are arranged in the arranging area 222;

[0038] The vibration component 3 includes a stepper motor 31 and a cam rotating member 32;

[0039] The stepper motor 31 is vertically and fixedly arranged on the first support plate 11, and the output end of the stepper motor 31 is fixedly connected to the lower end of the second support plate 21;

[0040] Therefore, there are three cam rotating members 32, which are horizontally arranged in parallel on the first support plate 11. One cam rotating member 32 is located directly below the screening area 221 and is fixedly connected to the upper end of the second support plate 21. The remaining two cam rotating members 32 are located directly below the arranging area 222 and are fixedly connected to the upper end of the second support plate 21.

[0041] In this embodiment, by setting up a support component 1, a screening and arranging component 2, and a vibration component 3, when in use, a plurality of scissor feet are placed in the screening area 221. The stepping motor 31 is turned on. The stepping motor 31 drives the second support plate 21 and the material tray 22 to rotate, further driving a plurality of cam rotating members 32 to rotate. The plurality of scissor feet on the material tray 22 are pushed against each other due to the action of centrifugal force, and some scissor feet are flipped. The scissor feet move from the screening area 221 to the arranging area 222 and finally move into the arranging grooves 223, realizing the orderly arrangement of the scissor feet. After the scissor feet are orderly arranged, the scissor feet in the arranging grooves 223 are sucked by a negative pressure suction cup. At this time, the scissor feet in the grooves have the same orientation, which is convenient for subsequent installation of the scissor feet into the keyboard.

[0042] In this embodiment, the cam rotating member 32 is set to three. The first cam rotating member 32 is located directly below the screening area 221, and the remaining two are located directly below the arranging area 222. Such a setting enables the scissor feet on the material tray 22 to move from the screening area 221 towards the arranging area 222 during the rotation of the material tray 22 following the cam rotating member 32.

[0043] Please refer to Figure 1 , the cam rotating member 32 includes a lower fixed cylinder 321, an upper fixed cylinder 322, and a cam 323. The lower fixed cylinder 321 and the upper fixed cylinder 322 are respectively fixedly connected to the first support plate 11 and the material tray 22. The cam 323 is arranged between the lower fixed cylinder 321 and the upper fixed cylinder 322. The lower end and the upper end of the cam 323 are respectively inserted into the lower fixed cylinder 321 and the upper fixed cylinder 322.

[0044] By setting up the lower fixed cylinder 321, the upper fixed cylinder 322, and the cam 323, the two connecting shafts arranged at the upper and lower ends of the cam 323 do not overlap with the center of the cam 323, enabling the cam 323 to drive the material tray 22 to perform eccentric rotation during rotation.

[0045] Please refer to Figure 1 , the lower end of the cam 323 is rotatably inserted into the lower fixed cylinder 321, and the upper end of the cam 323 is fixedly inserted into the upper fixed cylinder 322.

[0046] Such a setting enables the cam 323 to rotate relative to the lower fixed cylinder 321, ensuring the rotational stability of the cam rotating member 32.

[0047] Please refer to Figure 1, further comprising a material selection component 4, the material selection component 4 includes a guide rail mechanism 41 and a first brush 42, there are two guide rail mechanisms 41 which are symmetrically arranged on the front and back sides of the second support plate 21, the front and back ends of the first brush 42 are respectively fixedly connected to the two guide rail mechanisms 41, and the middle part of the first brush 42 extends into the material tray 22.

[0048] By arranging the guide rail mechanism 41 and the first brush 42, the guide rail mechanism 41 can drive the first brush 42 to move back and forth above the material tray 22. The cross-section of the first brush 42 is T-shaped. Since the middle part of the first brush 42 extends into the material tray 22, the cleaning of the scissor feet can be realized. Or when the scissor feet enter the arrangement area 222 from the screening area 221 under the action of centrifugal force, they will contact the first brush 42, and the cleaning of the scissor feet is also realized.

[0049] Please refer to Figure 1 and Figure 2 , the guide rail mechanism 41 includes linear guide rails 411, a slide table 412 and a slider 413. There are two linear guide rails 411 which are symmetrically arranged on the front and back sides of the second support plate 21. Each linear guide rail 411 is provided with the slide table 412, and the slider 413 is arranged on the slide table 412. The front and back ends of the first brush 42 are respectively fixedly connected to the two sliders 413.

[0050] By arranging the linear guide rails 411, the slide table 412 and the slider 413, the slide table 412 can slide linearly on the linear guide rails 411, thereby driving the slider 413 to move, and finally realizing the back-and-forth movement of the first brush 42.

[0051] Please refer to Figure 1 , the material selection component 4 further includes cylinders 43 and a second brush 44. There are two cylinders 43 which are symmetrically arranged front and back on the two sliders 413. The front and back ends of the second brush 44 are respectively fixedly connected to the telescopic ends of the two cylinders 43.

[0052] The arranged second brush 44 can also clean the scissor feet. In addition, after the scissor feet are arranged, by opening the cylinders 43, the telescopic ends of the cylinders 43 move downward, which can drive the second brush 44 to move downward, separate the screening area 221 and the arrangement area 222, and realize the separation of the scissor feet in the two areas.

[0053] Please refer to Figure 1 , the support component 1 further includes a base 12. The base 12 is arranged below the first support plate 11. There are two support ridges symmetrically arranged on the left and right at the upper end of the base 12. The first support plate 11 is horizontally arranged on the two support ridges and fixedly connected to the support ridges.

[0054] The provided base 12 is used to support the first support plate 11, enhancing the stability of the device.

[0055] Please refer to Figure 1 , several shock - proof feet 13 are provided at the lower end of the base 12.

[0056] The provided shock - proof feet 13 can enhance the shock - absorption of the device, making the noise generated during the operation of the device smaller and the overall stability of the device better.

[0057] Please refer to Figure 4 , it further includes a housing 5, and the support assembly 1, the screening and arranging assembly 2, and the vibration assembly 3 are all arranged inside the housing 5.

[0058] The provided housing 5 is used to protect the internal mechanical parts such as the support assembly 1, the screening and arranging assembly 2, and the vibration assembly 3.
