Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] like Figure 1 As shown, a sorting station 100 for assembling keyboards according to one embodiment of this utility model includes a support 10, a base plate 20, multiple light panels 30, and a camera 40. The base plate 20 is supported on the support 10 and includes a transparent area for placing components such as scissor-switch keys and keycaps. Multiple light panels 30 are mounted on the support 10 and are positioned at different locations below the base plate 20 to illuminate the base plate 20 from different directions. The camera 40 is positioned below the base plate 20 to capture images of the keyboard components on the base plate 20 and perform component sorting through system comparison. The sorting station 100 in this embodiment uses an improved light panel 30, which ensures that the brightness of each position on the base plate 20 is the same, thereby allowing components such as scissor-switch keys and keycaps to cast the correct shadows on the base plate 20 for the camera 40 to capture.

[0027] Specifically, the lamp panel 30 includes a mounting plate 31 and multiple rows of LED beads 32 fixed on the mounting plate 31 to ensure sufficient brightness for illumination of the base plate 10, and the angle between each row of LED beads 32 and the mounting plate 31 is different. Figure 3 and 6As shown, the LEDs 32 furthest from the base plate 20 are more upright, with a larger angle between them and the mounting plate 31. The angle between the LEDs 32 closer to the base plate 20 and the mounting plate 31 decreases progressively. Furthermore, preferably, multiple LEDs 32 in the same row have the same angle with the mounting plate 31. This arrangement ensures uniform brightness on the base plate 20, guaranteeing projection quality and ensuring the camera 40 correctly acquires images.

[0028] For example Figure 1 As shown, the base plate 20 is a rectangular plate, and a light panel 30 is provided below each side of the base plate 20. By shining light on the base plate 20 from different directions, the shadows of the components produced by the light projected from the opposite direction on the base plate 20 can be eliminated, allowing the camera 40 to correctly acquire the image information of the components. Of course, the base plate 20 can also be set to other shapes as needed, and this embodiment is not limited to that.

[0029] like Figure 2 and 3 As shown, a positioning plate 33 is fixed to one side of the mounting plate 31, and the LED bead 32 is fixed to the positioning plate 33. The positioning plate 33 is basically parallel to the mounting plate 31, so the closer the LED bead 32 is to the base plate 20, the larger the angle α between it and the positioning plate 33. The included angle α between the LED bead 32 and the positioning plate 33 increases as the distance between the LED bead and the base plate 20 increases. By fixing the LED bead 32 to the positioning plate 33, the positioning plate 33 can be removed when the entire LED bead 32 needs to be replaced, except when replacing the LED bead 32 individually, which provides greater flexibility. On the other side of the mounting plate 31, a cover 34 is fixed. A controller 35 and a fan 36 are installed between the cover 34 and the mounting plate 31. The controller 35 is connected to and controls the LED bead 32, while the fan 36 is used to dissipate heat from the controller 35 and the LED bead 32 to ensure the stable operation of the lamp board 30 for a long time.

[0030] Preferably, the cover 34 is fixed in the middle of the mounting plate 31, forming an installation space between it and the mounting plate 31. The controller 35 and the fan 36 are fixed within the installation space between the mounting plate 31 and the cover 34. Multiple strip-shaped grooves 37 are provided on both sides of the mounting plate 31. One strip-shaped groove 37 is an air inlet A, and the other is an air outlet B. When the fan 36 operates, air flows into the installation space between the cover 34 and the mounting plate 31 through the air inlet A, carrying away the heat from the controller 35 and the LED beads 32 before flowing out through the air outlet B.

[0031] Preferably, the light panel 30 is configured such that each row of LED beads 32 can be controlled individually, including the on / off state of the LED beads 32 and brightness adjustment, so as to fine-tune the light projected onto the base plate 20 according to the actual situation.

[0032] In one embodiment, to prevent shadows from forming on the base plate 20 or affecting brightness, the camera 40 is positioned below the light panel 30. Therefore, a certain space needs to be reserved between the light panels 30 for the camera 40. The light panel 30 and the base plate 20 are at a certain angle, and their positional relationship is non-parallel; for example, they can be perpendicular or other angular relationships. This non-parallel positional relationship reduces the projected area of ​​the light panel 30 on the base plate 20, i.e., the area it occupies on the base plate 20, thereby increasing the space reserved for the camera 40 to ensure the image capture effect of the camera 40.

[0033] It is easy to imagine that, in order to avoid obstructing the camera 40, an opening needs to be made in the bracket 10 so that the camera 40 can take an image of the components on the base plate 20, and the light panel 30 surrounds the opening.

[0034] like Figure 1 As shown, a telescopic support rod 11 is provided on the bracket 10, and the base plate 20 is fixed on the support rod 11. Therefore, its relative position with the camera 40 is adjustable to facilitate focusing, assist in adjusting brightness, or coordinate with the setup and operation of the gripping structure. The support rod 11 can be an adjustment mechanism such as a hydraulic rod, a cylinder, or a motor-driven lead screw; this embodiment is not limited to such mechanisms.

[0035] The lamp panel 30 is fixed to the bracket 10 by mounting feet 12 at both ends. For easy adjustment, the lamp panel 30 is angle-adjustable. Specifically, an arc-shaped groove 121 can be provided on the mounting feet 12, and the lamp panel 30 can be fixed in the arc-shaped groove 121. For example, studs can be provided at both ends of the mounting plate 31, and the studs can be inserted into the arc-shaped groove 121 and fixed with nuts. When it is necessary to adjust the angle of the lamp panel 30, the nuts can be loosened, the lamp panel 30 can be adjusted to the appropriate angle, and then the nuts can be tightened.

[0036] Preferably, the mounting foot 12 is also provided with a fixing groove 122 for fixing the lamp panel 30. The fixing groove 122 is a circular groove. Due to the setting angle, the arc-shaped grooves 121 are formed on the upper and lower sides of the fixing groove 122. Correspondingly, three studs are provided at each end of the mounting plate 31. The stud in the middle position is used to pass into the fixing groove 122 to determine and ensure the position of the lamp panel 30; while the upper and lower studs are respectively passed into the two lower arc-shaped grooves 121 to assist in adjusting the angle of the lamp panel 30 and ensure stability during angle adjustment.

[0037] In one embodiment, the base plate 20 consists of a transparent support plate 21 in the middle and a mounting frame 22 surrounding the support plate 21. The support plate 21 can be made of materials such as glass or acrylic, and the transparent area for placing components such as scissor arms and keycaps forms the surface of the support plate 21. The mounting frame 22 can be made of aluminum alloy, stainless steel, or other materials, and this embodiment is not limited thereto.

[0038] In one embodiment, the sorting station 100 is mounted on a keyboard assembly device, and the camera 40 is fixed in the remaining position of the assembly device. For ease of focusing and image acquisition, the position of the camera 40 can also be adjustable, or its position can be fixed and a device with an adjustable focal length can be used; this embodiment is not limited in this respect.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
