Description

Technical Field

[0001] This invention relates to the field of keyboard assembly technology, and more specifically to a flexible circuit board assembly device for a laptop backlit keyboard. Background Technology

[0002] The backlight module of a laptop keyboard consists of laminated light guide material and a flexible circuit board (FPC) that provides the light source. In the production process of assembling the FPC, the backlight module of a laptop keyboard is usually assembled manually, which is inefficient and prone to large assembly errors.

[0003] Therefore, there is an urgent need for an assembly machine that can be used for keyboard backlight module FPC; because in the production process of assembling keyboard backlight module FPC, the FPC needs to be precisely attached to the laminated light guide material by means of positioning holes. The assembly accuracy requirement is high, which leads to large errors and low efficiency in manual assembly. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flexible circuit board assembly device for laptop backlit keyboards. The device has a simple structure, realizes the automated operation of flexible circuit board loading and unloading, improves assembly efficiency, and reduces labor costs.

[0005] To address the aforementioned technical problems, this invention provides a flexible circuit board assembly device for a laptop backlit keyboard, characterized in that it includes a worktable, on which a carrying device, a material handling device, a camera device, an analysis device, and a robotic arm are arranged; the carrying device includes a slide table and a support platform, the support platform moving along the slide table; the material handling device includes a first adsorption mechanism, with first rotating shafts arranged on both sides of the first adsorption mechanism, and a driving device arranged on one side of the rotating shaft; the robotic arm includes a base, an arm, and a second adsorption mechanism.

[0006] Furthermore, the first adsorption device and the second adsorption device have the same structure, both including an adsorption plate, on which an adsorption disk is provided.

[0007] Furthermore, the workbench is provided with an outer frame, and the bearing device, material handling device, analysis device and robot are all located inside the outer frame.

[0008] Furthermore, indicator lights are provided on the outer frame.

[0009] Furthermore, the supporting device, the material handling device, and the camera device are arranged on the same straight line.

[0010] Furthermore, an adsorption base plate is provided on the support platform, an adsorption panel is provided on the adsorption base plate, a vacuum cavity is provided between the adsorption base plate and the adsorption panel, and adsorption holes are provided on the adsorption panel corresponding to the position of the vacuum cavity.

[0011] Furthermore, a power mechanism is provided on one side of the slide table. The power mechanism includes a motor, a first gear, and a second gear. The first gear is mounted on the drive shaft of the motor and is connected to the second gear. A threaded shaft is provided on the second gear, and the slide table is mounted on the threaded shaft.

[0012] Furthermore, the camera device employs a CCD camera.

[0013] The beneficial effects of this invention are as follows: By setting up a material handling device, a carrying device, an analysis device, a robotic arm, and a camera device working in coordination, with the material handling device, camera device, and carrying device all aligned in a straight line, the material handling device can flip the laminated light guide material by rotating its first rotating shaft after material handling is completed. The robotic arm then handles the material, the camera takes a picture, and the data is transmitted to the analysis device. After the analysis device completes the data analysis, it transmits it to the robotic arm, which adjusts its own motion path based on the data. Meanwhile, the operator only needs to place the FPC on the carrying device, and then the robotic arm assembles the laminated light guide material onto the FPC. Finally, the robotic arm transfers the assembled product to the conveyor belt for the next workstation. This design allows the robotic arm to complete the assembly process with high alignment accuracy requirements, reducing assembly errors and improving assembly efficiency. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0021] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

The material handling device 3, the camera device 4, and the carrying device 2 are all on the same straight line. When the material handling device 3 finishes handling the material, it can turn the laminated light guide material over by rotating its first rotating shaft 32. The robot arm 6 then handles the material, and the camera device 4 takes a picture. The data is transmitted to the analysis device 5, which analyzes the data and transmits it to the robot arm 6.
