Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to an automatic feeding machine 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.

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

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figures 1 to 8 As shown, this utility model provides an automatic feeding machine for keyboard frames. In one embodiment, it includes an upper transmission line; the upper transmission line includes several upper transmission devices 2, and a buffer transmission device 3 is arranged between two upper transmission devices 2; the buffer transmission device 3 includes a buffer base plate 31, and a buffer lifting mechanism 32 is arranged at one top end of the buffer base plate 31; the buffer lifting mechanism 32 is also driven and connected to a buffer lifting frame 33, and a buffer hopper is arranged on the buffer lifting frame 33; the buffer hopper includes a hopper base plate 34, and the top of the hopper base plate 34... Each side is connected to a vertical hopper plate 35; several sets of buffer transmission components 36 are arranged vertically at intervals on opposite sides of the two vertical hopper plates 35, and a drive shaft 37 is connected between each pair of opposite buffer transmission components 36 on the two vertical hopper plates 35; one end of the drive shaft 37 is arranged to movably pass through one of the vertical hopper plates 35, and a driven gear 38 is installed at one end of the drive shaft 37; a transmission drive component 4 is arranged on one side of one of the vertical hopper plates 35, and the transmission drive component 4 is also driven to connect a drive gear 41 for meshing with the driven gear 38.

[0018] In this embodiment, the upper-layer transmission line includes several upper-layer transmission devices 2, the number of which is adaptively set according to actual usage requirements and environment. In this embodiment, the upper-layer transmission line includes three upper-layer transmission devices 2, and a buffer transmission device 3 is arranged between two of the upper-layer transmission devices 2. A buffer transmission device 3 is also arranged at one end of one of the upper-layer transmission devices 2. The number and layout of the buffer transmission devices 3 can also be adaptively adjusted according to actual usage requirements. Simultaneously, it also includes a lower-layer transmission line located below the upper-layer transmission line, and an elevator (using existing equipment) arranged at one end of the upper-layer and lower-layer transmission lines. Furthermore, some of the upper-layer transmission devices... Below 2, a lifting cylinder is also arranged. During operation, the upper conveying device 2 can connect to the tray carrying the keyboard frame conveyed by the upstream conveying line and convey it to the predetermined loading position, that is, above the lifting cylinder. Then, the lifting cylinder lifts it up, and then the loading and transferring device 1 transfers it to the assembly position. If there is too much material being conveyed, the upper conveying device 2 can convey the tray to the buffer conveying device 3 for buffering. When the upper conveying device 2 needs to replenish the material, the buffer conveying device 3 will convey the tray back to the upper conveying device 2. The empty tray will be conveyed to the elevator, and the elevator will then convey it to the lower conveying line. Finally, the lower conveying line will convey it to the recycling position.

[0019] Specifically, the buffer lifting mechanism 32 (using an existing linear module) can drive the buffer hopper to rise or fall by driving the buffer lifting frame 33, thereby facilitating the reception of pallets. Multiple sets of buffer transfer components 36 are spaced apart in the height direction inside the buffer hopper to facilitate the stacking and storage of pallets. The transfer drive component 4 can mesh with the driven gear 38 of each layer of buffer transfer component 36 via the drive gear 41, thereby driving the driven gear 38 to rotate. The driven gear 38 is mounted on the drive shaft 37, which is connected to the buffer transfer component 36, thereby driving it to operate to receive or transfer pallets outward.

[0020] Preferably, in this embodiment, the buffer transmission component 36 includes a belt support bar 351 and two first synchronous pulleys. The two first synchronous pulleys are respectively installed at both ends of one side of the hopper vertical plate 35, and a first synchronous belt is wound between the two first synchronous pulleys. The belt support bar 351 is horizontally installed on one side of the hopper vertical plate 35, and the belt support bar 351 is located between the top and bottom edges of the first synchronous belt. The belt support bar 351 is located in the middle of the first synchronous belt and can support it. The two first synchronous pulleys are respectively installed at both ends of the hopper vertical plate 35, and the first synchronous belt is wound between the two first synchronous pulleys. The rotation of the drive shaft 37 drives the first synchronous pulleys to rotate, thereby realizing the cyclic movement of the first synchronous belt, which in turn drives the keyboard frame to be transmitted in a predetermined direction within the buffer hopper. At the same time, a first bearing is also installed on each of the two hopper vertical plates 35. The first synchronous pulleys are installed on the drive shaft 37, and both ends of the drive shaft 37 are respectively connected to a first bearing. The first bearings ensure the stability of the rotation of the drive shaft 37.

[0021] Furthermore, preferably, the transmission drive assembly 4 includes a drive fixed base 42, a drive translation cylinder 43 connected to one side of the drive fixed base 42, a drive translation seat 44 slidably arranged on one side of the drive fixed base 42 and connected to the drive translation cylinder 43, and a drive motor 45 mounted on the drive translation seat 44; the drive gear 41 is mounted on the output shaft of the drive motor 45. The drive translation cylinder 43 can drive the translation seat 44 to slide along the drive fixed base 42, thereby adjusting the position of the drive motor 45 so that the drive gear 41 can accurately mesh with the driven gear 38. After the drive motor 45 starts, its output shaft drives the drive gear 41 to rotate. Since the drive gear 41 meshes with the driven gear 38, and the driven gear 38 is mounted on the drive shaft 37, it can drive the drive shaft 37 to rotate, thereby realizing the operation of the buffer transmission assembly 36. At the same time, the drive translation cylinder 43 can also drive the translation seat 44 to move away from the hopper, thereby forming a clearance, so that the buffer lifting mechanism 32 can drive the hopper to lift and lower.

[0022] Meanwhile, the other end of the top of the buffer base plate 31 is also connected to a buffer vertical plate 311, and a first slide rail assembly is arranged vertically on one side of the buffer vertical plate 311; a first support frame 312 is also slidably connected to the first slide rail assembly, and the bottom sides of the buffer hopper are respectively arranged on the buffer lifting frame 33 and the first support frame 312. The bottom sides of the buffer hopper are respectively arranged on the buffer lifting frame 33 and the first support frame 312, which can ensure the stability of the buffer hopper's lifting and lowering.

[0023] In one embodiment, the device further includes a loading and transfer device 1; the loading and transfer device 1 includes two loading supports 11 and an X-axis translation frame 12; the two loading supports 11 are arranged in parallel and spaced apart, and a loading X-axis translation mechanism 13 is arranged on the top of one loading support 11, and a first guide rail assembly is arranged on the top of the other loading support 11; one end of the X-axis translation frame 12 is connected to the loading X-axis translation mechanism 13, and the other end of the X-axis translation frame 12 is slidably arranged on the first guide rail assembly; a loading Y-axis translation mechanism 14 is also arranged on the top of the X-axis translation frame 12, and the loading Y-axis translation mechanism 14 is also driven to connect a Y-axis translation seat 15; one of the Y-axis translation seats 15... A Z-axis lifting mechanism 16 for loading is also installed on the side, and the Z-axis lifting mechanism 16 is also driven and connected to a Z-axis lifting frame 17; an R-axis rotation mechanism 18 is also installed on the Z-axis lifting frame 17, and the R-axis rotation mechanism 18 is also driven and connected to a loading rotation plate 19; a loading gripper mechanism 191 is installed at each end of the loading rotation plate 19, and several loading transfer suction cups 192 are also installed in the middle of the bottom of the loading rotation plate 19; a loading vision mechanism 193 is arranged on each side of the Z-axis lifting frame 17, and a first through hole is opened on the loading rotation plate 19 at the position corresponding to the loading vision mechanism 193; the upper transmission line passes through the bottom of the two loading brackets 11.

[0024] Two parallel feeding brackets 11 are arranged at intervals, providing a stable support structure for the entire device. One end of the X-axis translation bracket 12 is connected to the feeding X-axis translation mechanism 13, and the other end is slidably arranged on the first guide rail assembly. This structural design allows the X-axis translation bracket 12 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 13. The feeding Y-axis translation mechanism 14 can drive the Y-axis translation seat 15 to move along the Y-axis direction. The feeding Z-axis lifting mechanism 16 can drive the Z-axis lifting bracket 17 to move up and down. The R-axis rotation mechanism 18 (including a rotary motor) can drive the feeding rotary plate 19 to rotate. With the cooperation of the above mechanisms, the feeding gripper mechanism 191 can be driven to perform translation, lifting, and rotation movements, facilitating the transfer of the keyboard frame by the feeding gripper mechanism 191. At the same time, several feeding transfer suction cups 192 are also installed in the middle of the bottom of the feeding rotary plate 19. The system can adsorb the keyboard frame, ensuring stability during keyboard frame transfer. In addition, it is equipped with a loading vision mechanism 193 (preferably, the loading vision mechanism 193 includes a vision fixing plate 1931 connected to one side of the Z-axis lifting frame 17, a camera fixing block 1932 connected to the upper part of one side of the vision fixing plate 1931, a loading detection camera 1933 mounted vertically on the camera fixing block 1932, a light source mounting plate 1934 connected to the lower part of one side of the vision fixing plate 1931, and a ring light source 1935 mounted on the light source mounting plate 1934 and located below the loading detection camera 1933), which can position the keyboard frame for accurate transfer. The loading rotating plate 19 is also equipped with a photoelectric sensor, and a second through hole is opened on the loading rotating plate 19 corresponding to the photoelectric sensor. The photoelectric sensor is used to sense whether the loading gripper mechanism 191 has gripped the keyboard frame.

[0025] In this embodiment, the X-axis translation mechanism 13 and the Z-axis lifting mechanism 16 can be linear modules, while the Y-axis translation mechanism 14 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 15 is connected to one end of the Y-axis slider. The Z-axis lifting mechanism 16 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.

[0026] In one embodiment, the loading gripper mechanism 191 includes a gripper mounting plate 1911 connected to one end of the top of the loading rotary plate 19, a gripper lifting cylinder 1912 mounted on one side of the gripper mounting plate 1911, a gripper lifting plate 1913 connected to the gripper lifting cylinder 1912, and a loading clamping cylinder 1914 mounted on the lower part of one side of the gripper lifting plate 1913. The loading clamping cylinder 1914 also drives two gripper translation plates 1915, and each gripper translation plate 1915 has a loading clamping rod 1916 connected to one side. The gripper lifting cylinder 1912 can drive the gripper lifting plate 1913 to move up and down, thereby adjusting the height position of the loading clamping rod 1916. Through the extension and retraction of the loading clamping cylinder 1914, the gripper translation plate 1915 can be controlled to drive the loading clamping rod 1916 to perform clamping or releasing actions, thereby realizing the gripping or releasing of the keyboard frame.

[0027] Preferably, in this embodiment, the loading clamping rod 1916 has an L-shaped structure, and the L-shaped vertical end of the loading clamping rod 1916 is connected to the gripper translation plate 1915, while the L-shaped horizontal end of the loading clamping rod 1916 is arranged on one side of the loading rotating plate 19.

During the loading and transfer process, the clamping support plate 1918 can simultaneously support the keyboard frame, cooperating with the adsorption effect of the loading and transfer suction cup 192 to form a double protection, effectively avoiding the risk of the keyboard frame falling due to insufficient adsorption force or unstable clamping.

[0028] Meanwhile, a pad 194 is connected to each of the two lower ends of one side of the gripper lifting plate 1913, and a second guide rail assembly is arranged on one side of each pad 194; the gripper translation plate 1915 is arranged on the second guide rail assembly; an upper limit block 195 is also installed on the top of the loading rotary plate 19, and one end of the upper limit block 195 extends to the upper end of the L-shaped horizontal end of the loading clamping rod 1916; a limit screw 196 is also installed on one end of the upper limit block 195 in the vertical direction.

At the same time, the limit screw 196 can limit the upward stroke of the gripper lifting cylinder 1912.

[0029] In addition, an upper clamping block 197 is installed at the bottom of the loading rotary plate 19, corresponding to the clamping tray 1918, and an extension block 198 extends downward from one bottom end of the upper clamping block 197; the extension block 198 is arranged above the clamping tray 1918, and a first buffer pad is connected to the bottom of the extension block 198. Two upper clamping blocks 197 are provided on each side of the bottom of the loading rotary plate 19.
