[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Reference Figures 1 to 6As shown, this utility model provides an automatic keycap assembly device. In one embodiment, it includes a keycap assembly mechanism 1, a secondary positioning mechanism 2, and an assembly table mechanism 3. The keycap assembly mechanism 1 includes two assembly stands 11 and an assembly sliding frame 12. The two assembly stands 11 are arranged in parallel and spaced apart, and each of the two assembly stands 11 has a first guide rail assembly on its top. The bottom ends of each assembly sliding frame 12 are slidably arranged on a first guide rail assembly. A first translation mechanism 13 is also installed on one side of one of the assembly stands 11, and the first translation mechanism 13 is also driven to connect a first moving base 1. 4; The top of the first movable seat 14 is connected to the bottom of the assembly sliding frame 12; A second translation mechanism 15 is also installed on one side of the assembly sliding frame 12, and the second translation mechanism 15 is also driven to connect to the assembly sliding plate 16; A first lifting mechanism 17 is installed on one side of the assembly sliding plate 16, and the first lifting mechanism 17 is also driven to connect to the assembly lifting frame 18; A keycap assembly module 19 is also installed at the bottom of the assembly lifting frame 18; The secondary positioning mechanism 2 is arranged on one side between the two assembly uprights 11, and the assembly platform mechanism 3 is arranged on the other side between the two assembly uprights 11.

[0015] In this embodiment, the first translation mechanism 13, the second translation mechanism 15, and the first lifting mechanism 17 can all be existing linear modules. With their cooperation, they can drive the keycap assembly module 19 to perform translational and lifting movements, thus facilitating the keycap assembly module 19 to assemble the keycaps. During operation, the external keycap robot first transfers the keycaps to be assembled onto the secondary positioning mechanism 2. The secondary positioning mechanism 2 further positions the keycaps. Simultaneously, the keyboard robot will move the keyboard frame (at this time, the corresponding position of the keyboard frame is already aligned with the balance bar assembly machine)... The keyboard frame is then positioned by the assembly platform mechanism 3 (with the balance bar assembled). The keycap assembly module 19 then picks up the keycaps from the secondary positioning mechanism 2 and assembles them onto the keyboard frame. After assembly, the keyboard robot moves the keycaps to the next process. In addition, in this embodiment, a crossbeam connects the two assembly stands 11, and a balance bar detection camera 10 is installed on the crossbeam. The balance bar detection camera 10 is located above the assembly platform 32 and can detect the position of the balance bar on the keyboard frame in advance, thereby improving the assembly accuracy.

[0016] In one embodiment, the secondary positioning mechanism 2 includes a positioning base plate 21, a positioning lifting mechanism 22 mounted on the positioning base plate 21, a positioning lifting seat 23 connected to the positioning lifting mechanism 22, and a contour suction plate 24 connected to the top of the positioning lifting seat 23; the top of the contour suction plate 24 is integrally connected to an adsorption support 25, and the top of the adsorption support 25 is also provided with a keycap contour groove; a first mounting hole is provided in the keycap contour groove, and a positioning suction nozzle 26 is also installed in the first mounting hole; a first air source connector 27 communicating with the positioning suction nozzle 26 is also installed at one end of the contour suction plate 24; a connecting plate 28 is connected to each of the top two ends of the positioning base plate 21, and a keyboard contour plate 29 is connected between the tops of the two connecting plates 28; the keyboard contour plate 29 is located above the contour suction plate 24, and a keycap contour hole is also provided on the keyboard contour plate 29 at the position corresponding to the adsorption support 25.

[0017] The keyboard contour plate 29 simulates a real keyboard, with multiple keycap contour holes set according to the actual number and position of keycaps. The keycap contour groove on the top of the adsorption support 25 is used to support the keycaps. The first air source connector 27 can be connected to a negative pressure air source to adsorb and limit the keycaps via the positioning nozzle 26. The positioning lifting mechanism 22 can drive the positioning lifting seat 23 to move up and down, thereby adjusting the position of the adsorption support 25. In this embodiment, the positioning lifting mechanism 22 adopts a motor screw transmission method. At the same time, in order to improve the stability of the lifting of the positioning lifting seat 23, the top of the positioning base plate 21 is also provided with two first through holes, and each of the first through holes is connected to a slide rail fixing plate 20 on one side of its inner wall. A second guide rail assembly is also arranged on one side of each slide rail fixing plate 20 in the vertical direction. The two ends of the positioning lifting seat 23 are respectively slidably connected to a second guide rail assembly.

[0018] In one embodiment, the assembly platform mechanism 3 includes an assembly fixing frame 31 and an assembly platform 32 mounted on the top of the assembly fixing frame 31; a first vacuum suction cup 33 is mounted on the top of the assembly platform 32, and a second air source connector communicating with the first vacuum suction cup 33 is also mounted on one end of the assembly platform 32; a first positioning pin 34 is also mounted on the top of the assembly platform 32; and a magnet 35 is also mounted on the top of the assembly platform 32.

[0019] The first vacuum suction cup 33 on the assembly platform 32 is used to adsorb the keyboard frame placed on it, ensuring that it is placed stably when assembling the keycaps; the first positioning pin 34 is used to quickly position the keyboard frame; multiple magnets 35 are provided, corresponding to the keycaps that need to be installed with balance bars, which can initially adsorb the balance bars to avoid assembly failure due to their movement when assembling the keycaps. Meanwhile, the assembly platform mechanism 3 also includes an assembly cleaning component; the assembly cleaning component includes a cleaning mounting base arranged on one side of the assembly fixing frame 31, a fixing rod 36 installed on the cleaning mounting base, a cleaning air blowing seat 37 installed on the fixing rod 36, and a bamboo-joint nozzle 38 installed on one side of the cleaning air blowing seat 37; one end of the cleaning air blowing seat 37 is also equipped with a third air source connector that communicates with the bamboo-joint nozzle 38. The third air source connector can be connected to an air source, and then airflow is sprayed outward through the bamboo-joint nozzle 38 to clean dust and impurities on the assembly platform 32, ensuring that the keyboard frame can be placed flat on the assembly platform 32.

[0020] In one embodiment, the keycap assembly module 19 includes an assembly connecting plate 191, a third translation mechanism 192, and a plurality of suction cup mounting strips 193. The assembly connecting plate 191 is connected to the bottom of the assembly lifting frame 18, and a bearing mounting plate 194 is connected to each of the bottom ends of the assembly connecting plate 191. The third translation mechanism 192 is installed at the bottom of the assembly connecting plate 191 along the moving direction of the first translation mechanism 13, and the third translation mechanism 192 is also driven to connect an adjustment translation plate 195. The adjustment translation plate 195 is located between two bearing mounting plates 194, and a first movable plate 196 is connected to each of the bottom ends of the adjustment translation plate 195. A plurality of oval guide holes are spaced apart on one side of the lower part of the first movable plate 196. The oval guide holes are opened in the vertical direction. A plurality of suction cup mounting strips 193 are arranged side by side between two first movable plates 196, and each suction cup mounting strip 193 is integrally connected to an upper bearing mounting plate 194 at each of its top ends. A connecting block 1931 is included; a first connecting shaft 1932 is also installed on the upper connecting block 1931, and a first guide wheel 1933 is integrally connected to one end of the first connecting shaft 1932; the first guide wheel 1933 is movably arranged in the oval guide hole; each of the bottom ends of the suction cup mounting strip 193 is integrally connected to a lower connecting block 1934, and a second connecting shaft 1935 is also installed on the lower connecting block 1934; a second mounting hole is also provided on the lower part of one side of the bearing mounting plate 194, and a first bearing 1936 is also installed in the second mounting hole; the second connecting shaft 1935 is connected to the first bearing 1936; a number of keycap assembly blocks 1937 are installed at intervals along the length direction of the bottom of the suction cup mounting strip 193, and a contoured slot is also provided at the bottom of the keycap assembly block 1937; a vacuum adsorption hole is provided in the contoured slot, and a fourth air source connector communicating with the vacuum adsorption hole is also installed on the top of the suction cup mounting strip 193.

[0021] There are six suction cup mounting strips 193. The number and shape of the keycap assembly blocks 1937 at the bottom of the suction cup mounting strips 193 are consistent with the actual keycaps (some special keys require separate installation). The contoured slots at the bottom of the keycap assembly blocks 1937 match the shape of the keycaps. The vacuum suction holes are connected to an air source through a fourth air source connector, which can generate a vacuum suction force to firmly attach the keycaps to the keycap assembly blocks 1937, ensuring the stability of the keycaps during the gripping and assembly process. At the same time, during the assembly process, the third translation mechanism 192 can... The adjustment sliding plate 195 is moved, and when it moves, it drives the first guide wheel 1933 to move through the oval guide hole. This, in turn, applies a pushing force to the upper part of the suction cup mounting strip 193 via the first connecting shaft 1932. The lower part of the suction cup mounting strip 193 is rotatably connected to the bearing mounting plate 194 via the second connecting shaft 1935 and the first bearing 1936. Therefore, when the upper part of the suction cup mounting strip 193 is subjected to force, it will drive the suction cup mounting strip 193 to swing, thereby adjusting the assembly angle of the keycap assembly block 1937 to smoothly assemble the keycap. In addition, to ensure the consistency of the installation positions of several suction cup mounting strips 193, an equal-height washer 1938 is also fitted on the second connecting shaft 1935, and the equal-height washer 1938 is located between the lower connecting block 1934 and the first bearing 1936.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
