[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figures 1 to 4 As shown, this utility model provides an automatic assembly device for a keyboard balance bar. In one embodiment, it includes a balance bar feeding mechanism 1 and a balance bar assembly mechanism 2 arranged on one side of the balance bar feeding mechanism 1. The balance bar assembly mechanism 2 includes a first stand 21, a first robotic arm 22 installed on the top of the first stand 21, and an assembly mounting plate 23 connected to the first robotic arm 22. An assembly clamping cylinder 24 is also installed at the bottom of the assembly mounting plate 23, and the assembly clamping cylinder 24 is also driven to connect two assembly clamping seats 25. An assembly clamping block 26 is installed on each opposite side of the two assembly clamping seats 25, and an assembly clamping groove 27 is opened at the lower part of each opposite side of the two assembly clamping blocks 26. A side limiting component 28 for limiting the balance bar is also installed on one side of the assembly clamping cylinder 24.

[0016] In this embodiment, the first robotic arm 22 can be an existing free robotic arm, which can drive the assembly clamping cylinder 24 to move in three-dimensional space. The assembly clamping cylinder 24 can drive the two assembly clamping seats 25 to move closer or further away from each other, and then the assembly clamping block 26 clamps the balance bar from the balance bar feeding mechanism 1 and assembles it into the corresponding hole in the keyboard frame. At the same time, an assembly clamping groove 27 is opened on the lower part of each of the two assembly clamping blocks 26 on opposite sides, which can make the assembly clamping block 26 firmly clamp the balance bar and prevent the balance bar from falling off during movement. In addition, a side limiting component 28 is provided to limit the side of the balance bar and ensure the stability of the balance bar transfer.

[0017] Preferably, in this embodiment, a first mounting groove is inclined downward on one side of the assembly clamping seat 25, and the lower part of the first mounting groove extends to the bottom of the assembly clamping seat 25; a first mounting hole extending into the first mounting groove is also provided on the other side of the assembly clamping seat 25, and a cup-head screw 29 is installed in the first mounting hole; the assembly clamping block 26 is arranged in the first mounting groove and installed on the cup-head screw 29. This structural design allows the assembly clamping block 26 to be easily installed and fixed on the assembly clamping seat 25, facilitating assembly and disassembly. It allows for quick replacement of the corresponding assembly clamping block 26 for different types and sizes of balance bars, offering strong versatility. Furthermore, an assembly clamping plate 20 extends downward from the bottom of the assembly clamping block 26, and an assembly clamping groove 27 is formed on the lower part of one side of the assembly clamping plate 20. The shape and size of the assembly clamping groove 27 can be designed according to the specific shape and size of the balance bar, thereby achieving precise clamping of the balance bar.

[0018] Furthermore, the side limiting assembly 28 includes a limiting mounting plate connected to one side of the assembly clamping cylinder 24; a side limiting block 281 is integrally connected to the bottom of the limiting mounting plate; the side limiting block 281 has an L-shaped structure, and the L-shaped horizontal end of the side limiting block 281 extends to be arranged between the two assembly clamping seats 25; a side limiting baffle 282 is also connected to the L-shaped horizontal end of the side limiting block 281. The function of the side limiting baffle 282 is to laterally limit the balance bar during clamping and assembly, and to provide more reliable lateral support for the balance bar, preventing lateral displacement of the balance bar during clamping and assembly.

[0019] In one embodiment, the balance bar feeding mechanism 1 includes a first feeding frame 11, a feeding support 12 installed on the top of the first feeding frame 11, a feeding base plate 13 connected to the top of the feeding support 12, and a feeding push plate 14 slidably arranged on one end of the top of the feeding base plate 13; a feeding fixing seat 15 is also installed in the middle of the top of the feeding base plate 13, and a feeding hopper plate 16 is also connected to one side of the feeding fixing seat 15 in the vertical direction, and the balance bar is movably sleeved on the feeding hopper plate 16; one end of the feeding push plate 14 extends to the bottom of the feeding hopper plate 16, and a first contoured slot for accommodating the balance bar is also opened at the top of one end of the feeding push plate 14; a feeding translation cylinder 17 connected to the feeding push plate 14 is also installed at the bottom of the feeding base plate 13.

[0020] To improve assembly efficiency, in this embodiment, the balance bar feeding mechanism 1 includes four feeding modules. Each feeding module includes the aforementioned feeding push plate 14, feeding hopper plate 16, feeding translation cylinder 17, and related components. The balance bars are stacked and sleeved on the feeding hopper plate 16, and the feeding hopper plate 16 is also movably sleeved with a hopper pressing block 182. The hopper pressing block 182 is located at the top of the stacked balance bars and is used to drive the balance bars to move down along the feeding hopper plate 16 under the action of gravity. The feeding push plate 14 slides under the drive of the feeding translation cylinder 17, catches the balance bars falling from the feeding hopper plate 16 through the first contouring slot, and pushes them forward to the loading position, waiting for the balance bar assembly mechanism 2 to pick up the balance bars.

[0021] Preferably, in this embodiment, a hopper base 18 is also installed at the other top end of the feeding base plate 13, and a feeding fixing seat 15 is installed at one top end of the hopper base 18; a first guide groove is provided on the top of the hopper base 18 along its length, and one end of the feeding push plate 14 is inserted into the first guide groove; a first notch is also provided at one end of the feeding push plate 14, and a first proximity switch 181 is installed at the other top end of the hopper base 18 corresponding to the first notch. When the feeding push plate 14 moves, the first guide groove plays a guiding role, and the first proximity switch 181 can detect whether the feeding push plate 14 has moved the balance bar to the predetermined feeding position, so that the background control balance bar assembly mechanism 2 can clamp the balance bar. At the same time, a second notch is provided on each side of the other top end of the hopper base 18. The second notch plays a role in avoiding obstruction, so that the assembly clamping cylinder 24 can drive the two assembly clamping blocks 26 to clamp the balance bar.

[0022] Furthermore, a first linear guide assembly is arranged along its length at one top end of the feeding base plate 13, and a linear guide connecting seat 19 is slidably arranged on the first linear guide assembly; the feeding push plate 14 is mounted on the linear guide connecting seat 19; the output shaft of the feeding translation cylinder 17 is also connected to a cylinder connecting plate 171, and the upper part of the cylinder connecting plate 171 is connected to one side of the linear guide connecting seat 19. The first linear guide assembly and the linear guide connecting seat 19 further improve the movement accuracy and stability of the feeding push plate 14. Simultaneously, a cylinder limiting block 172 is also connected to one end of the first linear guide assembly at the top of the feeding base plate 13, and a limiting screw 173 is also installed on the cylinder limiting block 172. The limiting screw 173 is used to limit the movement of the feeding push plate 14, thereby improving the safety of operation. In addition, the balance bar feeding mechanism 1 also includes a hopper partition 174, which is arranged on one side of the feeding hopper plate 16. This can prevent the balance bar assembly mechanism 2 from hitting the feeding hopper plate 16 when it moves, thereby improving the safety of equipment operation.

[0023] 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.
