Description

Technical Field

[0001] This utility model relates to the field of laptop keyboard technology, specifically to a scissor-switch tool for picking up keyboard keys for laptops. Background Technology

[0002] In the automated production process of laptop keyboards, the precise cutting of the key scissor-switch mechanism (i.e., the key support structure) is one of the key processes. As a precision plastic part, the key scissor-switch mechanism is characterized by its small size, diverse shapes, and fragile surface.

[0003] However, existing keyboard scissor-feed grippers still have some drawbacks in practical use: most existing scissor-feed grippers are fixed structures, which can only vertically grip horizontally placed workpieces. When the scissor feet are tilted or flipped, the grippers cannot adaptively adjust the angle, resulting in gripping deviation or detachment, increasing the gripping failure rate. Moreover, additional flipping mechanisms or manual pre-adjustment are required, increasing equipment costs and process complexity.

[0004] To address this issue, we designed a keyboard scissor-switch tool for laptops. Utility Model Content

[0005] The purpose of this invention is to provide a keyboard scissor-switch tool for a laptop computer, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a keyboard scissor-switch tool for a laptop computer, comprising an adjustment component and a moving component. The adjustment component includes an adjustment plate, an adjustment bolt rotatably connected between the inner walls of the two sides of the adjustment plate, an adjustment motor fixedly connected to the outer wall of the adjustment plate, the drive end of the adjustment motor passing through the adjustment plate and connected to the adjustment bolt, a moving block threadedly connected to the adjustment bolt, a rack fixedly connected to the bottom end of the moving block, and a half gear meshing with the bottom end of the rack.

[0007] Furthermore, a rotating shaft is fixedly connected to the half gear, and the rotating shaft is rotatably connected to the inner walls of the front and rear sides of the adjusting plate. A rotating block is fixedly connected to the rotating shaft, and a gripper is fixedly connected to the bottom end of the rotating block.

[0008] Furthermore, the moving component includes a first slide rail and a second slide rail, which are placed crosswise.

[0009] Furthermore, a first screw is rotatably connected to the inner walls of both sides of the first slide rail, and a first slider is threadedly connected to the first screw, with the first slider slidably connected to the bottom end of the first slide rail.

[0010] Furthermore, a first motor is fixedly connected to the outer wall of the first slide rail, and the drive end of the first motor passes through the side wall of the first slide rail and is connected to the first screw.

[0011] Furthermore, the bottom end of the first slider is fixedly connected to the top end of the second slide rail, and the inner walls on both sides of the second slide rail are rotatably connected to the second screws. The second slider is threadedly connected to the second screws, and the second slider is slidably connected to the bottom end of the second slide rail.

[0012] Furthermore, a second motor is fixedly connected to the outer wall of the second slide rail, and the drive end of the second motor passes through the side wall of the second slide rail and is connected to the second screw.

[0013] Furthermore, the bottom end of the second slider is fixedly connected to a telescopic cylinder, and the bottom end of the telescopic cylinder is fixedly connected to the top end of the adjusting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the rotational motion of the motor is converted into the angular rotation of the gripper by the adjustment component. The gripper direction can be dynamically adjusted according to the placement angle of the scissor legs, such as tilting or flipping, which solves the problem of gripping failure caused by angular deviation of traditional fixed grippers and improves the gripping success rate.

[0016] 2. In this utility model, a moving component is used to drive the first screw and the second screw through the first motor and the second motor respectively, so as to realize the precise displacement of the material picking device in the XY plane. Compared with the traditional single-axis moving structure, it can quickly cover any position in the working area and avoid blind spots in material picking caused by mechanical limitations. It is especially suitable for scenarios where keyboard scissor switches are densely arranged on the material tray. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a keyboard scissor-switch tool for a laptop computer, comprising an adjustment component and a moving component. The adjustment component includes an adjustment plate 4, with an adjustment bolt 5 rotatably connected between the inner walls of both sides of the adjustment plate 4. An adjustment motor 6 is fixedly connected to the outer wall of the adjustment plate 4, and the drive end of the adjustment motor 6 passes through the adjustment plate 4 and is connected to the adjustment bolt 5. A moving block 7 is threaded onto the adjustment bolt 5, and a rack 8 is fixedly connected to the bottom end of the moving block 7. A half gear 9 is meshed with the bottom end of the rack 8, and a rotating shaft 11 is fixedly connected to the half gear 9. The rotating shaft 11 is rotatably connected to the inner walls of the front and rear sides of the adjustment plate 4, and a rotating block 10 is fixedly connected to the rotating shaft 11. A gripper 12 is fixedly connected to the bottom end of the rotating block 10.

[0024] In practice, after the adjusting motor 6 is started, its drive end drives the adjusting bolt 5 to rotate between the inner walls of both sides of the adjusting plate 4. The moving block 7, which is threadedly connected to the adjusting bolt 5, moves along the axial direction of the adjusting bolt 5 on the adjusting plate 4 as the adjusting bolt 5 rotates. The bottom end of the moving block 7 is fixedly connected to the rack 8. When the moving block 7 moves up and down, the rack 8 also moves accordingly. Since the bottom end of the rack 8 meshes with the half gear 9, the linear movement of the rack 8 is converted into the rotational movement of the half gear 9. The half gear 9 is fixedly connected to the rotating shaft 11, which is rotatably connected to the inner walls of the front and rear sides of the adjusting plate 4. The rotation of the half gear 9 drives the rotating shaft 11 to rotate. The rotating block 10 is fixedly connected to the rotating shaft 11, and the gripper 12 is fixedly connected to the bottom end of the rotating block 10. The rotation of the rotating shaft 11 ultimately achieves the angle adjustment of the gripper 12, enabling it to grip the scissor blade at a suitable angle.

[0025] See Figure 2 The moving component includes a first slide rail 1 and a second slide rail 2, which are placed crosswise.

[0026] In practice, the first slide rail 1 and the second slide rail 2 respectively enable the device to move forward, backward, left, and right, and their cross placement can prevent motion interference.

[0027] See Figure 2 and Figure 4 The inner walls of the two sides of the first slide rail 1 are rotatably connected to a first screw 13. A first slider 15 is threaded onto the first screw 13 and slidably connected to the bottom end of the first slide rail 1. A first motor 17 is fixedly connected to the outer wall of the first slide rail 1. The drive end of the first motor 17 passes through the side wall of the first slide rail 1 and is connected to the first screw 13. The bottom end of the first slider 15 is fixedly connected to the top end of the second slide rail 2. The inner walls of the two sides of the second slide rail 2 are rotatably connected to a second screw 14. A second slider 16 is threaded onto the second screw 14 and slidably connected to the bottom end of the second slide rail 2. A second motor 18 is fixedly connected to the outer wall of the second slide rail 2. The drive end of the second motor 18 passes through the side wall of the second slide rail 2 and is connected to the second screw 14.

[0028] In practical implementation, when the device needs to move in the front-back direction, the first motor 17 starts, and its drive end drives the first screw 13 to rotate on both sides of the inner wall of the first slide rail 1. Since the first slider 15 is threadedly connected to the first screw 13, under the action of threaded transmission, the first slider 15 will slide along the bottom end of the first slide rail 1. The bottom end of the first slider 15 is fixedly connected to the top end of the second slide rail 2, and the sliding of the first slider 15 will drive the entire second slide rail 2 and other components mounted on it to move in the front-back direction. After completing the front-back movement and positioning, if it is necessary to move in the left-right direction, the second motor 18 starts to work. The drive end of the second motor 18 drives the second screw 14 to rotate on both sides of the inner wall of the second slide rail 2, and the second slider 16, which is threadedly connected to the second screw 14, will slide at the bottom end of the second slide rail 2. The bottom end of the second slider 16 is fixedly connected to the telescopic cylinder 3, which in turn drives the entire adjustment assembly and the gripper 12 to move in the left-right direction. Through the coordinated control of the first motor 17 and the second motor 18, the positioning of the material handling device at any position in the plane can be realized.

[0029] See Figure 1 The bottom end of the second slider 16 is fixedly connected to the telescopic cylinder 3, and the bottom end of the telescopic cylinder 3 is fixedly connected to the top end of the adjusting plate 4.

[0030] In practice, the telescopic cylinder 3 extends, causing the gripper 12 to descend and grasp the scissor legs. After the grasping is complete, the telescopic cylinder 3 retracts, causing the gripper 12 to rise.

[0031] Working Principle: During operation, the first motor 17 and the second motor 18 control the moving component to move the picking device above the position of the scissor legs. Then, based on the placement angle of the scissor legs, the adjusting motor 6 is activated, and the angle of the gripper 12 is adjusted by the adjusting component to match the gripping part of the scissor legs. Next, the telescopic cylinder 3 extends, driving the gripper 12 to descend and grab the scissor legs. After grabbing, the telescopic cylinder 3 retracts, and the moving component moves the grabbed scissor legs to the designated position for placement, thus realizing omnidirectional picking operation of the laptop keyboard scissor legs.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
