[0034] Embodiment three

[0035] Referring to Figure 7 and Figure 8 , and on the basis of embodiment one, it is further obtained that the voice coil position detection assembly 4 has a mounting frame 4001 installed on one side of the DDR mounting base 1001, the mounting frame 4001 is installed with a Z-axis screw module 4002 close to one side of the DDR mounting base 1001, a Z-axis guide rail 4004 is arranged close to the rear of the Z-axis screw module 4002 on one side of the DDR mounting base 1001 close to the Z-axis screw module 4002, a Z-axis servo motor 4003 matched with each other is installed at the bottom end of the Z-axis screw module 4002, a lower pressing fixed plate 4005 is installed at the front end of the Z-axis guide rail 4004, and a lower pressing block 4009 adaptively matched with the gauge body 1016 is installed through lower pressing linear bearings 4007 at the front and rear end positions on one side of the lower pressing fixed plate 4005 away from the Z-axis screw module 4002, top ends of the mounting frame 4001 are provided with line sweep profilers 4010 matched with each other with the voice coil body 1017 and the gauge body 1016, and sheet metal covers 4011 are arranged below the two line sweep profilers 4010, a lower pressing guide shaft 4006 is installed through the upper and lower ends of the lower pressing fixed plate 4005, a lower pressing spring 4008 is arranged around the outer circle of the lower pressing guide shaft 4006, and the upper and lower ends of the lower pressing spring 4008 respectively abut against the upper and lower opposite surfaces of the lower pressing block 4009 and the lower pressing fixed plate 4005, the voice coil height adjusting assembly 5 has an adjusting mounting base 5001 installed on one side of the DDR mounting base 1001, and the adjusting mounting base 5001 is located below the turntable body 1003, a Z-axis adjusting module 5002 is arranged on one side of the adjusting mounting base 5001 close to the turntable body 1003, Z-axis adjusting motors 5003 matched with each other with the Z-axis adjusting module 5002 are installed at the front and rear ends of the adjusting mounting base 5001, an adjusting mounting plate 5004 is slidingly installed on one side of the Z-axis adjusting module 5002 close to the turntable body 1003, and an adjusting block 5005 is installed at the top end of the adjusting mounting plate 5004, and the adjusting block 5005 is adaptively matched with the jacking block 1009.

[0036] Specifically, the Z-axis screw module 4002 moves downward, the lower pressing block 4009 presses the sound gauge body 1016, the line scanning profiler 4010 starts to scan the height difference between the bottom reference surface of the sound gauge body 1016 and the coil center line of the voice coil body 1017, the Z-axis adjustment module 5002 moves upward, the adjusting block 5005 pushes the jacking block 1009 to move upward, so that the voice coil body 1017 moves upward, when the line scanning profiler 4010 scans the same height difference as the set height difference, the Z-axis adjustment module 5002 stops and exits downward, and then the Z-axis screw module 4002 moves upward to separate from the sound gauge body 1016.

[0037] In actual operation, the assembly drives the turntable body 1003 to rotate clockwise through the DDR and the DDR mounting base 1001. Four sets of product jigs are installed on the turntable body 1003, which are arranged as a feeding station, an assembling station, an adjusting station, and a discharging station. When producing products of different sizes, the corresponding jigs can be quickly replaced through the quick-change knob 1015, and two groups of voice coil bodies 1017 can be taken at one time through the four-axis robot body 2003. The voice coil body 1017 has a thin wall thickness. In order to prevent the voice coil body 1017 from being deformed during taking, the three-finger electric claw 2005 is used for supporting the material taking, and the inner hole of the push plate body 2019 is only slightly larger than the outer circle formed by the three jaw bodies 2008, so that the push plate body 2019 can well push the voice coil body 1017. When producing voice coil bodies 1017 of other different sizes, the corresponding jaw bodies 2008 can be quickly replaced through the jaw quick-change 2007, and the corresponding push plate body 2019 can be quickly replaced through the floating quick-change 2018 and the push plate quick-change 2020. The electric push rod 2009 can stably push the push plate body 2019 up and down through the guide rail body 2013 and the guide push plate 2014, so that the push plate body 2019 can push the voice coil body 1017. In order to prevent the push plate body 2019 from damaging the voice coil body 1017, the push plate body 2019 is in a compressed floating state under the action of the sound gauge body 1016 and the floating compression spring 2017, realizing soft contact.

[0038] When the turntable is in place, the Y-axis movement module 3002 moves forward, and the two jaw bodies 3008 and 3009 clamp the sound gauge body 1016, so that the sound gauge body 1016 is deformed and the outer diameter is reduced, facilitating the insertion of the voice coil body 1017 into the sound gauge body 1016. When the jaw body 2008 clamps the sound gauge body 1016, the two-finger electric claw 3007 is released, and the Y-axis movement module 3002 moves backward.

[0039] After that, the Z-axis screw module 4002 moves downward, so that the lower pressing block 4009 presses the sound gauge body 1016, and the wire scanning profiler 4010 starts to scan the height difference between the bottom reference surface of the sound gauge body 1016 and the coil center line of the voice coil body 1017. The Z-axis adjustment module 5002 moves upward, and the adjusting block 5005 pushes the jacking block 1009 to move upward, so that the voice coil body 1017 moves upward. When the wire scanning profiler 4010 scans the same height difference as the set height difference, the Z-axis adjustment module 5002 stops and exits downward. After that, the Z-axis screw module 4002 moves upward to separate from the sound gauge body 1016.

[0040] That is, according to the actual situation, the jig substrate 1007 close to the feeding detection sensor 1005 is limited to the sound gauge body 1016 feeding station. According to the clockwise movement direction of the turntable body 1003, the second station is determined to be the voice coil body 1017 assembly station, the third station is the height adjustment station of the voice coil body 1017, and the fourth station is the finished product unloading station after the sound gauge body 1016 and the voice coil body 1017 are assembled.

[0041] The specific steps are as follows: after the sound gauge body 1016 is fed, the turntable body 1003 rotates 90°, and then the three-finger electric claw 2005 clamps the voice coil body 1017 from the voice coil tray 6. When the product jig of the sound gauge body 1016 is above the second station, the Y-axis movement module 3002 moves forward, and the two-finger electric claw 3007 clamps the sound gauge body 1016, and then the claw body 2008 moves downward to clamp the top guide part of the sound gauge body 1016.

[0042] At the same time of clamping, the voice coil body 1017 is loosened and falls down until the two-finger electric claw 3007 loosens the sound gauge body 1016 and makes it fall to the bottom. After ensuring that the voice coil body 1017 falls to the bottom, the push plate body 2019 moves upward and controls the three-finger electric claw 2005 to loosen. Then the four-axis robot body 2003 moves upward, and then the turntable body 1003 rotates 90°, so that the wire scanning profiler 4010 scans the height difference between the bottom reference surface of the sound gauge body 1016 and the coil center line of the voice coil body 1017, and adjusts the voice coil body 1017 by moving upward through the Z-axis adjustment module 5002. When the wire scanning profiler 4010 scans the same height difference as the set height difference, the Z-axis adjustment module 5002 stops and exits downward. After that, the Z-axis screw module 4002 moves upward to separate from the sound gauge body 1016 until the turntable body 1003 rotates 90°, thereby completing the finished product unloading of the sound gauge body 1016 and the voice coil body 1017.

[0043] Although the embodiments of the present application have been shown and described, it is to be understood that for the purpose of the present application, the embodiments can be changed, modified, replaced and varied in many ways without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
