Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides a material picking device for the scissor legs of a keyboard, comprising a mounting frame 1, a movable frame 2 is provided on the inner side of the mounting frame 1, a longitudinal translation mechanism 3 for driving the movable frame 2 to translate longitudinally is provided on the top of the mounting frame 1, a movable seat 4 is slidably connected to the inner side of the mounting frame 1, both ends of the bottom of the movable seat 4 are fixedly connected to a first cylinder 6, the output ends of the two first cylinders 6 are provided with a material picking mechanism 7 for grabbing the scissor legs of the keyboard, and a lateral translation mechanism 5 for driving the movable seat 4 to translate horizontally is provided at one end of the movable frame 2.

[0021] By controlling the longitudinal translation mechanism 3 to drive the movable frame 2 to translate longitudinally, the material picking mechanism 7 is also translated longitudinally. By driving the movable seat 4 to translate laterally through the transverse translation mechanism 5, the material picking mechanism 7 is translated laterally. In this way, the material picking mechanism 7 can be adjusted to the corresponding material picking position, and then the first cylinder 6 is controlled to make the movable seat 4 translate downward, so that the material picking mechanism 7 grabs the keyboard scissor legs, thereby realizing automatic material picking of the keyboard scissor legs, greatly reducing the amount of manual labor, and thus improving the assembly efficiency of the notebook keyboard.

[0022] The longitudinal translation mechanism 3 includes a second cylinder 31, which is fixedly connected to the top of the mounting frame 1. The output end of the second cylinder 31 is fixedly connected to a fixed seat 32, which is fixedly connected to the top of the movable frame 2. Guide blocks 34 are fixedly connected to both ends of the top of the movable frame 2. The top of the mounting frame 1 is fixedly connected to two parallel guide rods 33. The two guide blocks 34 are respectively slidably connected to the two guide rods 33, and the ends of the two guide rods 33 are fixedly connected to limit blocks 35. By controlling the second cylinder 31, the fixed seat 32 is longitudinally translated, causing the movable frame 2 to longitudinally translate. The two guide rods 33 can guide the guide blocks 34, thereby ensuring that the movable frame 2 remains stable during translation.

[0023] The lateral translation mechanism 5 includes a screw 51, which is rotatably connected to the inner side of the movable frame 2. The movable seat 4 is threadedly connected to the screw 51. A first motor 52 is fixedly mounted on one end of the movable frame 2. The output shaft of the first motor 52 is fixedly connected to the screw 51. A guide rail 53 arranged parallel to the screw 51 is fixedly connected to the inner side of the movable frame 2. The top end of the movable seat 4 is slidably connected to the guide rail 53. By activating the first motor 52 to rotate the screw 51, the movable seat 4 is caused to translate laterally along the guide rail 53, thereby adjusting the lateral position of the material retrieving mechanism 7.

[0024] Among them, the material-taking mechanism 7 includes a mounting base 71, the two ends of the top of the mounting base 71 are fixedly connected to the output ends of the two first cylinders 6 respectively, the inner side of the mounting base 71 is rotatably connected to two parallel rotating shafts 72, one end of each of the two rotating shafts 72 is fixedly connected to a transmission gear 74, the two transmission gears 74 are meshed with each other, a second motor 75 is fixedly installed on one end of the mounting base 71, the output shaft of the second motor 75 is fixedly connected to one of the rotating shafts 72, and a plurality of grabbing members 73 are provided on the two rotating shafts 72, and the plurality of grabbing members 73 are equidistantly distributed along the axial direction of the rotating shaft 72;

The end of the spring 735 away from the slider 732 is fixedly connected to the inner wall of the mounting slot 734. The spring 735 cushions the clamping block 733, preventing it from clamping the keyboard scissor legs with excessive force and damaging them.

[0026] Working principle: By controlling the second cylinder 31, the fixed seat 32 is longitudinally translated, the movable frame 2 is longitudinally translated, and the clamping claw 731 is longitudinally translated to the corresponding position, and then the first motor 52 is started to rotate the screw rod 51, which makes the movable seat 4 translate laterally along the guide rail 53, so that the claw 731 is laterally translated to the corresponding position, and finally the second motor 75 is started to rotate the rotating shaft 72, so that the two transmission gears 74 rotate toward each other, which makes the two clamping claws 731 at the same horizontal position rotate toward each other and makes the clamping block 733 clamp the keyboard scissor legs, thereby realizing automatic material removal of the keyboard scissor legs.
