[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-4 As shown, the wooden plucked string instrument knob assembly mechanism of this utility model includes a base 1, a placement plate 4 slidably connected to the middle of the base 1, an end fixing component 5 fixedly installed on one side of the top of the placement plate 4, two sets of support components 6 fixedly installed on the other side of the top of the placement plate 4, and the support component 6 located in the middle is lower than the support component 6 on the side, a support column 8 fixedly installed on one side of the top of the base 1, a crossbar 9 fixedly installed on the top of one side of the support column 8, an L-shaped block 11 slidably connected to the surface of the crossbar 9, and a liftable knob assembly machine body 14 is provided on the front of the L-shaped block 11.

[0020] Specifically, the end fixing component 5 and the support component 6 set at the top of the placement plate 4 can support the wooden plucked string instrument and limit and fix the knob assembly part. When assembling the knob, the stability of the wooden plucked string instrument is effectively ensured, and the knob assembly is avoided from being misaligned and needing to be reworked repeatedly, thereby improving the efficiency of knob assembly of wooden plucked string instruments.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the end fixing component 5 of the wooden plucked string instrument knob assembly mechanism of this utility model includes a fixing plate 501 and two limiting strips 502. The fixing plate 501 is fixedly connected to one side of the top of the placement plate 4, and two symmetrically arranged limiting strips 502 are slidably connected to the top of the fixing plate 501.

[0022] A convex groove 503 is provided in the middle of the fixed plate 501. Two convex sliders 504 are slidably connected inside the convex groove 503. The tops of the two convex sliders 504 are fixedly connected to the center of the bottom of the limiting strip 502. Positive and negative trapezoidal screws 505 are rotatably connected to both sides of the inner wall of the convex groove 503. The two ends of the positive and negative trapezoidal screws 505 are threadedly connected to the center of the corresponding convex sliders 504. A servo motor 506 is fixedly installed on the side of the fixed plate 501. One end of the servo motor 506 is fixedly connected to one end of the positive and negative trapezoidal screws 505.

[0023] Specifically, the servo motor 506 drives the rotation of the positive and negative trapezoidal lead screws 505, which in turn drives the movement of two convex sliders 504, which in turn drives the movement of the limit strip 502, thereby limiting the assembly end.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wooden plucked string instrument knob assembly mechanism of this utility model includes a support component 6 comprising a support platform 601 and a U-shaped support block 605. The bottom end of the support platform 601 is fixedly connected to the top end of the placement plate 4. An installation groove 602 is provided at the center of the support platform 601. An inverted T-shaped column 603 is nested inside the installation groove 602. The top end of the inverted T-shaped column 603 is fixedly connected to the center of the bottom end of the U-shaped support block 605. An electric push rod 604 is fixedly installed at the bottom of the installation groove 602. The telescopic end of the electric push rod 604 is fixedly connected to the bottom end of the inverted T-shaped column 603.

[0025] Specifically, the U-shaped support block 605 is raised and lowered by the electric push rod 604, and the wooden plucked string instrument is supported by the U-shaped support block 605.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wooden plucked string instrument knob assembly mechanism of this utility model has a first electric slide rail 2 fixedly installed at the center of the base 1, a first slide block slidably connected to the surface of the first electric slide rail 2, a mounting base 3 fixedly installed at the top of the first slide block, the top of the mounting base 3 fixedly connected to the bottom of the placement plate 4, and a knob placement box 7 fixedly installed on the side of the top of the base 1.

[0027] A second electric slide rail 10 is fixedly installed at the top of the crossbar 9. A second slide block is slidably connected to the surface of the second electric slide rail 10. The top of the second slide block is fixedly connected to the bottom of the L-shaped block 11.

[0028] Specifically, through the cooperation of the first electric slide rail 2 and the second electric slide rail 10, the first electric slide rail 2 can realize the lateral movement of the placement plate 4, and the second electric slide rail 10 can realize the longitudinal movement of the knob assembly machine body 14, ensuring that the knob assembly machine body 14 and the assembled knob are accurately aligned.

[0029] The front of the L-shaped block 11 is fixedly mounted with a third electric slide rail 12. The surface of the third electric slide rail 12 is slidably connected with a third slide block. The front of the third slide block is fixedly mounted with a mounting plate 13. The mounting plate 13 is fixedly connected to the back of the knob assembly machine body 14 by screws.

[0030] Specifically, the third electric slide rail 12 drives the third electric slide block to rise and fall, thereby driving the knob assembly machine body 14 to rise and fall, so as to realize the knob assembly machine body 14 to assemble the knob.

[0031] In specific implementation, when using the wooden plucked string instrument knob assembly mechanism to assemble knobs, firstly, the wooden plucked string instrument to be assembled is placed in the placement plate 4 and supported by the support component 6. Then, the servo motor 506 is turned on, and the rotation of the positive and negative trapezoidal lead screw 505 driven by the servo motor 506 drives the two convex sliders 504 to move towards the center. The movement of the convex sliders 504 drives the limit strips 502 to move, so that the two limit strips 502 contact the two sides of the assembly end and limit the assembly end. Then, the worker places the knob to be assembled in the corresponding assembly position, and then turns on the first electric slide rail 2 and the second electric slide rail 10. The first electric slide rail 2 drives the placement plate 4 to move laterally, and the second electric slide rail 10 drives the knob assembly machine body 14 to move longitudinally, so that the knob assembly machine body 14 is aligned with the knob. Then, the third electric slide rail 12 and the knob assembly machine body 14 are turned on to assemble the knob.

[0032] It should be noted that the knob assembly machine body 14 is a commercially available device known to those skilled in the art. We are simply using it here without making any structural or functional improvements. We will not go into detail here. For example, a knob assembly machine produced by "Quick Twist" company could be used.
