The outer edge 8 on the orifice plate 4 facilitates the clamping mechanism to clamp the orifice plate 4, and the acquisition and transfer of the sound unit are achieved by clamping and transferring the orifice plate 4. This not only avoids the situation in which the clamping assembly 203 directly contacts the sound unit and causes damage to the sound unit, but also by replacing the orifice plate 4 with a positioning hole 5 adapted to the shape and size of the sound unit, the clamping assembly 203 can be adapted to sound units of different shapes and sizes.

[0034] The sorting mechanism 2 includes a swing arm driver 201, a swing arm 202 and a clamping assembly 203 capable of clamping the orifice plate 4 through the outer edge 8. The clamping assembly 203 is arranged at one end of the swing arm 202, and the swing arm 202 is arranged on the swing arm driver 201. The swing arm 202 is driven by the swing arm driver 201 to move in the vertical and horizontal directions, so that the orifice plate 4 can be separated from and docked with the base 1, and the orifice plate 4 can be transferred to the vibration measuring mechanism 3, the assembly equipment and the recycling equipment.

[0035] The swing arm driving machine 201 includes a shell 2011 provided with a vibration measuring mechanism 3, and a rotating component 2012 and a lifting component 2013 arranged in the shell 2011.

[0037] Preferably, the clamping assembly 203 includes a U-shaped support plate 2031 and a damping pad 2032, one end of the U-shaped support plate 2031 is connected to the swing arm 202, and the U-shaped support plate 2031 is provided with a makeshift channel 9 running through the other end thereof, the width of the makeshift channel 9 is adapted to the width of the orifice plate 4, both sides of the makeshift channel 9 are provided with slide grooves 10 for inserting the outer edge 8, and the damping pad 2032 is arranged in the makeshift channel 9 for pressing the outer edge 8, when the swing arm 202 moves to align the slide grooves 10 on both sides of the U-shaped support plate 2031 with the outer edges 8 on both sides of the support plate on the base 1, the swing arm 202 can extend to allow the outer edge 8 to be relatively inserted into the slide grooves 10 on both sides of the U-shaped support plate 2031, and the outer edge 8 is pressed by the damping pad 2032, and the U-shaped support plate 2031 can be clamped on the orifice plate 4 by utilizing the extension and retraction of the swing arm 202.

[0038] The vibration measuring mechanism 3 includes a signal input module 301 and a vibration measuring module 302 which are arranged at intervals in the vertical direction, the swing arm 202 is located between the signal input module 301 and the vibration measuring module 302, a bracket 11 for installing the signal input module 301 and the vibration measuring module 302 is arranged on the shell 2011, the signal input module 301 and the vibration measuring module 302 are both arranged on the bracket 11 through a vertical driving component 12, the signal input module 301 and the vibration measuring module 302 are driven by the vertical driving component 12 to approach and move away from each other, so that the signal input module 301 and the vibration measuring module 302 can clamp, dock and separate the sound unit, and the swing arm 202 can enable the sound unit to directly reach between the signal input module 301 and the vibration measuring module 302 after retraction, so as to improve the test efficiency, and when the recovery equipment and the assembly equipment are respectively arranged on both sides of the shell 2011, the tested sound unit can be efficiently transferred to the recovery equipment and the assembly equipment through the left and right swinging of the swing arm 202.

[0039] The vertical drive assembly 12 includes a piston 1201, a sliding sealing plate 1202, a cylinder body 1203 and a piston rod 1204. Two piston chambers 13 filled with fluid medium corresponding to the signal input module 301 and the vibration measurement module 302 are arranged in the bracket 11, and a strip hole 14 connecting the piston chamber 13 is arranged on the bracket 11.

[0040] The piston 1201 is slidably set in the piston cavity 13 along the length direction of the swing arm 202, the sliding sealing plate 1202 is connected to the piston 1201 and slides and seals the strip hole 14, the sliding sealing plate 1202 is connected to one end of the swing arm 202, the cylinder body 1203 is set on the bracket 11 and connected to the piston cavity 13, the piston rod 1204 is slidably connected to the cylinder body 1203, and is connected to the corresponding signal input module 301 or the vibration measurement module 302.

[0041] The piston 1201 is driven to reciprocate by the extension and retraction of the swing arm 202, thereby pressurizing and depressurizing the fluid medium such as air or hydraulic oil in the piston chamber 13, thereby driving the piston rod 1204 to rise and fall, so as to realize the rise and fall of the signal input module and the vibration measurement module 302.

[0042] Furthermore, the cylinder body 1203 is always located between the piston 1201 and the strip hole 14 , thereby eliminating the need to provide a more complicated channel in the piston chamber 13 .

[0043] The working principle of the present invention is as follows:

[0044] The orifice plate 4 equipped with the sound unit is assembled to the base 1 in a manner of plugging the recessed portion 7 into the assembly hole 6, or the sound unit is placed in the positioning hole 5 on the orifice plate 4 assembled with the base 1. Then, the U-shaped support plate 2031 is driven by the swing arm 202 to move radially toward the base 1, so that the outer edges 8 on both sides of the orifice plate 4 are inserted into the slide grooves 10 on both sides of the U-shaped support plate 2031 and are pressed by the damping pads 2032. At this time, the orifice plate 4 is located in the make way channel 9 of the U-shaped support plate 2031. Then the swing arm 202 drives the U-shaped support plate 2031 to retract. At the same time, the swing arm 202 drives the piston 1201 to pressurize the fluid medium in the piston chamber 13 through the connecting piece and the sliding sealing plate 1202 in turn, and the cylinder body 1203 is connected with the piston chamber 13, so that the piston rod 1204 gradually approaches the sound unit on the U-shaped support plate 2031 under the push of the fluid medium, so that the vibration measurement module 302 on the upper piston rod 1204 abuts against the vibration module of the sound unit, and the signal input module 301 on the lower piston rod 1204 is connected with the signal input interface of the sound unit. The signal input module 301 supplies power to the sound unit and inputs an audio signal. After the vibration measurement unit converts the detected vibration of the sound unit into an electrical signal, it compares and analyzes it with the input audio signal to determine whether the sound effect of the sound unit meets the expectations. The swing arm 202 is driven to rotate by the rotating assembly 2012, and the sound unit loaded on the orifice plate 4 after the test can be transferred to the corresponding assembly equipment or recycling equipment.
