Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to an automatic feeding device for keyboard frames. Background Technology

[0002] In the keyboard scissor-switch pin assembly process, small and medium-sized enterprises mainly rely on manual labor for loading the keyboard frame. This involves manually transferring the keyboard frame to the corresponding assembly position and then assembling the scissor-switch pins into their respective positions within the frame. This method is inefficient, cannot meet the demands of large-scale production, and consumes a large amount of human resources, resulting in high labor costs and low enterprise profits. Meanwhile, some enterprises use simple robotic arms with vacuum suction cups to automatically pick up and load the keyboard frame. However, this design is simplistic, merely picking up the keyboard frame for transfer. During the transfer process, there is a risk that the keyboard frame may fall due to insufficient suction force. Therefore, improvements are needed. Utility Model Content

[0010] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0011] Reference Figures 1 to 4 As shown, this utility model provides an automatic feeding device for a keyboard frame. In one embodiment, it includes two feeding brackets 1 and an X-axis translation bracket 2. The two feeding brackets 1 are arranged in parallel and spaced apart. One feeding bracket 1 has a feeding X-axis translation mechanism 3 on its top, and the other feeding bracket 1 has a first guide rail assembly on its top. One end of the X-axis translation bracket 2 is connected to the feeding X-axis translation mechanism 3, and the other end of the X-axis translation bracket 2 is slidably arranged on the first guide rail assembly. The top of the X-axis translation bracket 2 is also provided with a feeding Y-axis translation mechanism 4, and the feeding Y-axis translation mechanism 4 is also driven and connected to a Y-axis. The Y-axis translation seat 5 is equipped with a Z-axis lifting mechanism 6 on one side, and the Z-axis lifting mechanism 6 is also driven and connected to a Z-axis lifting frame 7. The Z-axis lifting frame 7 is also equipped with an R-axis rotation mechanism 8, and the R-axis rotation mechanism 8 is also driven and connected to a loading rotation plate 9. A loading gripper mechanism 91 is installed at each end of the loading rotation plate 9, and several loading transfer suction cups 92 are installed in the middle of the bottom of the loading rotation plate 9. A loading vision mechanism 93 is arranged on each side of the Z-axis lifting frame 7, and a first through hole is opened on the loading rotation plate 9 at the position corresponding to the loading vision mechanism 93.

[0012] Two parallel feeding brackets 1 are arranged at intervals, providing a stable support structure for the entire device. One end of the X-axis translation bracket 2 is connected to the feeding X-axis translation mechanism 3, and the other end is slidably arranged on the first guide rail assembly. This structural design allows the X-axis translation bracket 2 to move smoothly back and forth along the first guide rail assembly in the X-axis direction under the drive of the feeding X-axis translation mechanism 3. The feeding Y-axis translation mechanism 4 can drive the Y-axis translation seat 5 to move along the Y-axis direction. The feeding Z-axis lifting mechanism 6 can drive the Z-axis lifting bracket 7 to move up and down. The R-axis rotation mechanism 8 (including a rotary motor) can drive the feeding rotary plate 9 to rotate. With the cooperation of the above mechanisms, the feeding gripper mechanism 91 can be driven to perform translation, lifting, and rotation movements, facilitating the transfer of the keyboard frame by the feeding gripper mechanism 91. At the same time, several feeding transfer suction cups 92 are also installed in the middle of the bottom of the feeding rotary plate 9. The system can adsorb the keyboard frame, ensuring stability during keyboard frame transfer. In addition, it is equipped with a loading vision mechanism 93 (preferably, the loading vision mechanism 93 includes a vision fixing plate 931 connected to one side of the Z-axis lifting frame 7, a camera fixing block 932 connected to the upper part of one side of the vision fixing plate 931, a loading detection camera 933 mounted vertically on the camera fixing block 932, a light source mounting plate 934 connected to the lower part of one side of the vision fixing plate 931, and a ring light source 935 mounted on the light source mounting plate 934 and located below the loading detection camera 933), which can position the keyboard frame for accurate transfer. The loading rotating plate 9 is also equipped with a photoelectric sensor, and a second through hole is opened on the loading rotating plate 9 corresponding to the photoelectric sensor. The photoelectric sensor is used to sense whether the loading gripper mechanism 91 has gripped the keyboard frame.

[0013] In this embodiment, the feeding X-axis translation mechanism 3 and the feeding Z-axis lifting mechanism 6 can be linear modules, while the feeding Y-axis translation mechanism 4 has two sets, using a motor and lead screw transmission method. Each lead screw is connected to a Y-axis slider, and the Y-axis translation seat 5 is connected to one end of the Y-axis slider. The feeding Z-axis lifting mechanism 6 has two sets, with each lead screw connected to a Y-axis slider and moving through the other Y-axis slider. With this structural design, two keyboard frames can be moved at one time, improving work efficiency.

[0014] In one embodiment, the loading gripper mechanism 91 includes a gripper mounting plate 911 connected to one top end of the loading rotary plate 9, a gripper lifting cylinder 912 mounted on one side of the gripper mounting plate 911, a gripper lifting plate 913 connected to the gripper lifting cylinder 912, and a loading clamping cylinder 914 mounted on the lower part of one side of the gripper lifting plate 913. The loading clamping cylinder 914 also drives two gripper translation plates 915, and each gripper translation plate 915 has a loading clamping rod 916 connected to one side. The gripper lifting cylinder 912 can drive the gripper lifting plate 913 to move up and down, thereby adjusting the height position of the loading clamping rod 916. Through the extension and retraction of the loading clamping cylinder 914, the gripper translation plate 915 can be controlled to drive the loading clamping rod 916 to perform clamping or releasing actions, thereby realizing the gripping or releasing of the keyboard frame.

[0015] Preferably, in this embodiment, the loading clamping rod 916 has an L-shaped structure, and the L-shaped vertical end of the loading clamping rod 916 is connected to the gripper translation plate 915, while the L-shaped horizontal end of the loading clamping rod 916 is arranged on one side of the loading rotating plate 9. A loading clamping block 917 extends downward from the L-shaped horizontal end of the loading clamping rod 916, and a clamping support plate 918 extends horizontally downward from the bottom of the loading clamping block 917 towards the lower part of the loading rotating plate 9. During the loading and transfer process, the clamping support plate 918 can simultaneously support the keyboard frame, working in conjunction with the adsorption effect of the loading and transfer suction cup 92 to form a double protection, effectively avoiding the risk of the keyboard frame falling due to insufficient adsorption force or unstable clamping.

[0016] Meanwhile, a pad 94 is connected to each of the two lower ends of one side of the gripper lifting plate 913, and a second guide rail assembly is arranged on one side of each pad 94; the gripper translation plate 915 is arranged on the second guide rail assembly; an upper limit block 95 is also installed on the top of the feeding rotary plate 9, and one end of the upper limit block 95 extends above the L-shaped horizontal end of the feeding clamping rod 916; a limit screw 96 is also installed on one end of the upper limit block 95 in the vertical direction. The gripper translation plate 915 can move smoothly on the second guide rail assembly, ensuring the stability of the feeding clamping rod 916 when clamping or releasing the keyboard frame. At the same time, the limit screw 96 can limit the upward stroke of the gripper lifting cylinder 912.

[0017] In addition, an upper clamping block 97 is installed at the bottom of the feeding rotary plate 9, corresponding to the clamping tray 918, and an extension block 98 extends downward from one bottom end of the upper clamping block 97; the extension block 98 is arranged above the clamping tray 918, and a first buffer pad is connected to the bottom of the extension block 98. Two upper clamping blocks 97 are provided on each side of the bottom of the feeding rotary plate 9. Through the cooperation between the upper clamping blocks 97 and the clamping tray 918, the stability of the keyboard frame clamping can be further improved.

[0018] 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.
