The sound film feeding mechanism 200, the gluing mechanism 300, the coil feeding mechanism 400 and the horn assembly blanking manipulator 500 are sequentially arranged around the turntable mechanism 100.
As shown in fig. 2, the sound membrane feeding mechanism 200 includes: a sound film vibration feeding tray 210 and a sound film feeding manipulator 220. A plurality of sound membranes 11 are placed in the sound membrane vibration feeding disc 210, under the action of the sound membrane vibration feeding disc 210, the sound membranes 11 are sequentially arranged to reach the discharge port of the sound membrane vibration feeding disc 210, and the sound membrane feeding manipulator 220 is used for transferring the sound membranes 11 at the discharge port of the sound membrane vibration feeding disc 210 to the turntable mechanism 100 one by one. Note that, the acoustic membrane vibration feeding tray 210 and the acoustic membrane feeding manipulator 220 of the present invention are both obtained by using the prior art.
The gluing mechanism 300 is used for gluing the sound membrane 11 on the turntable mechanism 100, so that the coil 12 is conveniently adhered to the surface of the sound membrane 11, and the loudspeaker assembly 10 is obtained. The specific structural design of the glue mechanism 300 will be described in detail below.
As shown in fig. 2, the coil feeding mechanism 400 includes: coil vibrations charging tray 410, coil material loading manipulator 420. A plurality of coils 12 are placed in the coil vibration feeding tray 410, and under the action of the coil vibration feeding tray 410, the plurality of coils 12 sequentially reach the discharge port of the coil vibration feeding tray 410, and the coil feeding manipulator 420 is used for transferring the coils 12 to the turntable mechanism 100 one by one.

The horn assembly blanking manipulator 500 transfers the obtained horn assembly 10 to the transfer line 600, and the transfer line 600 transfers the horn assembly 10 to the next station.
As shown in fig. 3, regarding the turntable mechanism 100, specifically, the turntable mechanism 100 includes: the turntable body 110 and a rotation driving part 120 for driving the turntable body 110 to rotate. The rotation driving part 120 is a motor reducer driving structure.
As shown in fig. 4, regarding the turntable mechanism 100, further, a plurality of jigs 130 are disposed on the turntable body 110, and the plurality of jigs 130 are distributed in an annular array with the rotation axis of the turntable body 110 as the center. The jig 130 is used for placing the sound membrane 11, the coil 12 and the loudspeaker assembly 10.
Next, a specific structure of the glue mechanism 300 will be described:
as shown in fig. 5, the glue mechanism 300 includes: a supporting seat 310, a lifting frame 320 and a lifting driving part 330. In this embodiment, the lifting driving part 330 is a motor screw driving structure, and the lifting frame 320 is provided with a threaded hole in threaded fit with the screw.
The lifting frame 320 is arranged on the supporting seat 310 in a reciprocating sliding manner along the vertical direction, and the lifting driving part 330 is in driving connection with the lifting frame 320; the lifting frame 320 is provided with a glue injection cylinder 340, and the cylinder body of the glue injection cylinder 340 is filled with glue.
Next, the operation principle of the glue mechanism 300 having the above-described structure will be described:
under the action of the turntable mechanism 100, the turntable mechanism 100 drives the sound membrane 11 to reach the gluing mechanism 300;
the lifting driving part 330 drives the lifting frame 320 to descend along the supporting seat 310, the lifting frame 320 drives the glue injection cylinder 340 to descend, and when a glue injection port of the glue injection cylinder 340 contacts with the surface of the sound membrane 11, the lifting driving part 330 stops driving;
the glue injection cylinder 340 is used for coating part of glue in the glue injection cylinder onto the surface of the sound film 11, after the glue injection is completed, the lifting driving part 330 is used for driving the lifting frame 320 to lift along the supporting seat 310, and the lifting frame 320 further drives the glue injection cylinder 340 to lift, so that a glue injection port of the glue injection cylinder 340 is separated from the surface of the sound film 11, and the turntable mechanism 100 can be conveniently rotated continuously.
As can be seen from the above description, the turntable body 110 is provided with a plurality of jigs 130, the jigs 130 are used for placing the sound membrane 11, the coil 12 and the speaker assembly 10, and the rotary driving portion 120 drives the turntable body 110 to rotate, so as to drive the sound membrane 11, the coil 12 and the speaker assembly 10 in the jigs 130 to rotate to reach the designated station.
Since the diaphragm 11 and the coil 12 are fine parts, the diameter of the diaphragm 11 is usually about 5CM, the diameter of the coil 12 is about 3CM, the diaphragm 11 and the coil 12 are easily affected by external air flow, and the diaphragm 11 and the coil 12 are easily thrown out under the action of centrifugal force in the process of rotating the turntable body 110.
To solve this technical problem, improvement of the specific structure of the jig 130 is required.
As shown in fig. 6 and 7, specifically, the jig 130 includes: the limiting outer ring 131, the supporting inner ring 132 and the negative pressure suction nozzle 133.
The supporting inner ring 132 is accommodated in the limiting outer ring 131, the supporting inner ring 132 has a height smaller than that of the limiting outer ring 131, and an accommodating chamber 134 (as shown in fig. 6) is formed between the supporting inner ring 132 and the limiting outer ring 131. The negative pressure suction nozzle 133 is disposed on the support inner ring 132 and is located in the accommodating chamber 134.
Through the structural improvement of the jig 130, the sound membrane 11 or the coil 12 can be more stably remained in the jig 130.
For example, the height of the supporting inner ring 132 is smaller than that of the limiting outer ring 131, and a receiving chamber 134 is formed between the supporting inner ring 132 and the limiting outer ring 131, so that the sound membrane 11 can be completely received in the receiving chamber 134, and the edge of the sound membrane 11 can be abutted against the inner side surface of the limiting outer ring 131.
In addition, by providing the negative pressure suction nozzle 133, the negative pressure suction nozzle 133 is disposed on the supporting inner ring 132 and is located in the accommodating chamber 134, so that the lower surface of the sound membrane 11 can be vacuum-adsorbed on the negative pressure suction nozzle 133, the negative pressure suction nozzle 133 generates negative pressure on the sound membrane 11, and the light and thin sound membrane 11 is not easily affected by the external air flow and flies away. In addition, in the process of gluing the sound membrane 11 by the gluing mechanism 300, the glue injection opening of the glue injection cylinder 340 is in contact with the surface of the sound membrane 11, and by setting the negative pressure suction nozzle 133, the damping glue at the negative pressure suction nozzle 133 can buffer the sound membrane 11, so as to prevent the sound membrane 11 from being damaged.
It should be further noted that, the negative pressure suction nozzle 133 in the present invention does not need to be externally connected with a vacuum negative pressure pipeline, and does not need to generate a vacuum adsorption effect through an external pipeline, so that the structure of the whole device becomes simpler, a complex structure is not needed, and the production cost of the whole device can be greatly reduced.
From the above, in order to improve the stability of the transportation of the diaphragm 11 or the coil 12, the structure of the jig 130 is improved, wherein one improvement is to provide a negative pressure suction nozzle 133. Although the negative pressure suction nozzle 133 can effectively prevent the sound membrane 11 from solving the corresponding technical problems, the negative pressure suction nozzle 133 of this structure also generates new problems.
The new problem is: on the one hand, in the process of blanking the assembled speaker assembly 10, the negative pressure suction nozzle 133 generates a negative pressure suction force on the sound membrane 11, so that the speaker assembly blanking manipulator 500 is difficult to take out the sound membrane 11 from the jig 130, and if the sound membrane 11 is forcibly taken out, the sound membrane 11 is also easy to deform; on the other hand, since the glue is applied to the contact portion between the center of the sound membrane 11 and the coil 12, it is not preferable to make the vacuum nozzle contact the center of the sound membrane 11 to perform blanking of the horn assembly 10.
In order to solve the above new technical problems, the present invention further improves the specific structures of the jig 130 and the horn assembly blanking manipulator 500.
As shown in fig. 6, specifically, the limiting outer ring 131 is provided with an avoidance gap 135; the outer side wall of the support inner ring 132 forms a relief incline 136.
As shown in fig. 8, the horn assembly blanking manipulator 500 includes a manipulator body 510 and a vacuum adsorption assembly 520 disposed on the manipulator body 510. It should be noted that, the robot body 510 may be obtained by using a conventional technique, and any conventional technique that can drive the vacuum adsorption assembly 520 to lift and rotate may be used.
Next, a specific structure of the vacuum adsorption module 520 will be described:
as shown in fig. 9, the vacuum adsorption assembly 520 includes: a hanging barrel 521, a hemispherical body 522, four vacuum nozzles 523, and a swing driving part 524 (shown in fig. 10).
As shown in fig. 10, it is pointed out that in the present invention, the vacuum suction assembly 520 includes and only includes four number of vacuum suction nozzles 523, and that none or one more vacuum suction nozzles 523 can produce good results.
As shown in fig. 10, the suspension tube 521 is fixed at the output end of the manipulator body 510, the hemisphere 522 is rotatably disposed on the suspension tube 521 (for example, reference numeral 528 in the drawing is a rotation axis) through a connection member 525, four vacuum nozzles 523 are inserted on the hemisphere 522, and the four vacuum nozzles 523 are distributed in an annular array with the central axis of the hemisphere as the center.
As shown in fig. 10, swing drive 524 drives hemisphere 522 to swing reciprocally through link 525. In this embodiment, the swing driving part 524 includes a motor (not shown) and a swing fork 526 provided at an output end of the motor, and a swing shaft 527 engaged with the swing fork 526 is provided on the connecting member 525.
Next, the working principle of the vacuum adsorption assembly 520 is described by matching the jig 130 and the robot body 510:
as shown in fig. 11 and 12, the motor drives the swing fork 526 to rotate to one side by an angle, the swing fork 526 further drives the connecting element 525 to rotate around the hanging drum 521 by an angle through the swing shaft 527, and the rotation of the connecting element 525 further drives the hemisphere 522 to rotate by an angle (the central axis of the hemisphere 522 is adjusted from the vertical state to the inclined state), so that the four vacuum nozzles 523 on the hemisphere 522 are also inclined (note that only one of the vacuum nozzles 523 is closest to the upper surface of the sound membrane 11 at this time);
as shown in fig. 12, the robot body 510 drives the whole vacuum adsorption assembly 520 to descend, one of the vacuum suction nozzles 523 closest to the upper surface of the sound membrane 11 will first contact with one side of the upper surface of the sound membrane 11, during the process of applying force to one side of the upper surface of the sound membrane 11 by the vacuum suction nozzle 523, the sound membrane 11 will be unevenly stressed, external air will enter from one of the points where the sound membrane 11 contacts with the negative pressure suction nozzle 133 (air leakage occurs at the contact point of the lower surface of the sound membrane 11 with the negative pressure suction nozzle 133), and then the sound membrane 11 will be easily separated from the negative pressure suction nozzle 133;
as shown in fig. 12, when the sound membrane 11 is separated from the negative pressure suction nozzle 133, the other three vacuum suction nozzles 523 will absorb the sound membrane 11, so that the periphery of the sound membrane 11 will be stably absorbed by the four vacuum suction nozzles 523 and will not fall easily;
as shown in fig. 13 and 14, after the sound membrane 11 is separated from the negative pressure suction nozzle 133, the manipulator body 510 drives the whole vacuum suction assembly 520 to rise, and simultaneously, the motor drives the swing fork 526 to rotate in the opposite direction by an angle, so that the central axis of the hemisphere 522 is readjusted to be in a vertical state;
the manipulator body 510 drives the whole vacuum adsorption assembly 520 to rotate to the upper side of the transmission assembly line 600, and the four vacuum suction nozzles 523 release negative pressure adsorption to the sound membrane 11, so that the whole loudspeaker assembly 10 can fall on the transmission assembly line 600.
As shown in fig. 6, it is to be specifically described that, in order to cooperate with the vacuum suction nozzles 523 to absorb and take out the sound film 11 in an inclined manner, an avoidance gap 135 is formed on the limiting outer ring 131, and meanwhile, an avoidance inclined surface 136 is formed on the outer side wall of the supporting inner ring 132, so that the avoidance gap 135 can effectively avoid one of the vacuum suction nozzles 523, and the avoidance inclined surface 136 can support and avoid the inclined sound film 11, so that the sound film 11 can be turned more stably. The opening of the avoidance gap 135 does not affect the wrapping of the sound membrane 11 by the limiting outer ring 131, and the whole sound membrane 11 can be stably contained in the containing cavity 134.
The invention also discloses a loudspeaker production process, which is realized by the loudspeaker production equipment 20, and comprises the following steps:
the sound membrane feeding mechanical arm 220 feeds the sound membrane 11 on the sound membrane vibration feeding disc 210 to the turntable mechanism 100;
the turntable mechanism 100 drives the sound membrane 11 to rotate to the gluing mechanism 300;

the turntable mechanism 100 drives the sound membrane 11 to rotate to the coil feeding mechanism 400;

the turntable mechanism 100 drives the horn assembly 10 to rotate to the position of the horn assembly blanking manipulator 500;
the horn assembly blanking manipulator 500 performs blanking of the horn assembly 10 at the turntable mechanism 100.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
