The sponge feeding component 1, the end cover feeding component 2 and a group of material moving components 6 are each provided between the collecting device 4 and the rotating table 5. A motor for driving the table of the rotating table 5 to rotate is provided at the bottom of the rotating table 5. A plurality of material receiving parts 51 are provided on the table of the rotating table 5 and the material receiving parts 51 can be arranged according to the feeding station, the gluing station, the bonding station and the unloading station. The positions are switched sequentially, and interval stations are provided between the gluing station and the bonding station, and between the bonding station and the unloading station. When the material receiving piece 51 moves to the interval station, the motor silencer sponge automatic bonding device will not perform any operation on the material on the material receiving piece 51; a countersunk hole 511 for placing the silencer sponge 7 is provided on the material receiving piece 51, so as to limit the silencer sponge 7, so that the silencer sponge 7 is not easy to slide off the material receiving piece 51 due to lack of limitation under the influence of inertia when the turntable 5 rotates.

[0048] The sponge loading component 1 is used to provide the silencer sponge 7 to the corresponding material moving component 6, and the material moving component 6 can move the silencer sponge 7 to the receiving piece 51 located at the loading station; the glue coating device 3 can spray glue to the silencer sponge 7 located at the glue coating station; the end cover loading component 2 is used to provide the motor end cover 8 to the corresponding material moving component 6, and the material moving component 6 can move the motor end cover 8 to the silencer sponge 7 located at the bonding station, so that the motor end cover 8 and the silencer sponge 7 are bonded to form a finished product; the collecting device 4 is used to collect the finished products provided by the corresponding material moving component 6, and the material moving component 6 can move the finished products located at the unloading station into the collecting device 4.

[0049] Through the above arrangement, the sponge feeding component 1 can provide the silencer sponge 7 to a corresponding group of material moving components 6, so that the silencer sponge 7 can be moved to the material receiving part 51 located at the feeding station through the material moving component 6, and then the rotating table 5 will move the material receiving part 51 to the gluing station by rotating, so as to spray glue onto the silencer sponge 7 through the gluing device 3, and then the rotating table 5 will move the material receiving part 51 and the silencer sponge 7 sprayed with glue to the bonding station together, at this time, the end cover feeding component 2 and the rotating table 5, the material shifting assembly 6 will move the motor end cover 8 provided by the end cover loading assembly 2 onto the silencer sponge 7, so that the motor end cover 8 and the silencer sponge 7 are bonded to form a finished product, and finally the rotating table 5 will move the receiving piece 51 and the finished product to the unloading station together, so that the finished product can be removed from the receiving piece 51 and moved into the collecting device 4 by the material shifting assembly 6 arranged between the collecting device 4 and the rotating table 5, thereby realizing the automatic assembly of the silencer sponge 7 and the motor end cover 8, which greatly improves the assembly efficiency.

The suction cup 641 is disposed at the bottom of the lifting platform 63, one end of the air guide pipe 642 is connected to the suction cup 641, and the other end of the air guide pipe 642 can be connected to the air extraction device (not shown in the figure). An air inlet is also provided on the air guide pipe 642, and the electric control valve is disposed at the air inlet and can control the switch of the air inlet. The electric control valve can be closed when the suction cup 641 abuts against the silencer sponge 7 or the motor end cover 8, so that the suction device can suck the gas in the air duct 642 and the suction cup 641 to form a negative pressure and adsorb the silencer sponge 7 or the motor end cover 8 on the suction cup 641; after the material picking device 64 is moved to the rotating table 5, the electric control valve is opened to allow the external gas to pass through the air inlet into the air duct 642 and the suction cup 641, so that the material can be separated from the suction cup 641 and fall onto the rotating table 5.

[0057] See also Figure 1 and Figure 2 The picking device 64 arranged between the collecting device 4 and the rotating table 5 includes an electromagnet 643 and a controller (not shown in the figure). The electromagnet 643 can adsorb the motor end cover 8. The controller is electrically connected to the electromagnet 643 and can control the switch of the electromagnet 643 so that the electromagnet 643 can be turned on when the electromagnet 643 is close to the material to be moved, so that the motor end cover 8 on the finished product can be adsorbed on the electromagnet 643; after the picking device 64 is moved to the collecting device 4, the electromagnet 643 is turned off, so that the finished product can fall into the collecting device 4.

[0058] Figure 5 is a stereogram of another embodiment of the present application, Figure 6 yes Figure 5 Schematic enlargement of area C in FIG. 1 , showing the receiving box. Figure 5 and Figure 6 In another embodiment provided in the present application, the material taking device 64 disposed between the end cover feeding assembly 2 and the rotating table 5 includes an electromagnet 643 and a controller. Figure 7 is along Figure 5 A schematic cross-sectional view of the central axis of the central material receiving box, wherein only part of the rotating platform is shown. Figure 7The material receiving member 51 includes a material receiving box 512, a piston 513 and a magnetic member 514. The material receiving box 512 has an air storage chamber formed therein. The top of the material receiving box 512 has a material receiving groove for placing the sound-absorbing sponge 7. A piston 513 is provided in the air storage chamber. A compression spring is provided between the piston 513 and the bottom wall of the air storage chamber. A magnetic member 514 is provided on the top of the piston 513. A vent hole 5121 leading to the air storage chamber is provided on the groove wall of the material receiving groove. The glue coating device 3 can pass the sound-absorbing sponge 7 to the sound-absorbing sponge 7. Glue is sprayed from the top of the sound sponge 7 to form a glue drop 9, one end of the air hole 5121 is located between the piston 513 and the bottom wall of the air storage chamber, and the other end of the air hole 5121 faces the glue drop 9; the electromagnet 643 on the material picking device 64 arranged between the end cover feeding assembly 2 and the rotating table 5 can form a magnetic field that repels each other with the magnetic part 514, so that when the electromagnet 643 adsorbs the motor end cover 8 close to the silencer sponge 7, the magnetic part 514 can drive the piston 513 to move downward.

[0059] Through the above arrangement, when the glue coating device 3 sprays glue onto the silencer sponge 7, the glue will form two large glue drops 9 on the top of the silencer sponge 7; when the electromagnet 643 adsorbs the motor end cover 8 close to the top of the silencer sponge 7, since the electromagnet 643 can form a magnetic field that repulses the magnetic part 514, the magnetic part 514 will be repelled away from the electromagnet 643 and drive the piston 513 to move downward, and the piston 513 will squeeze the air between the piston 513 and the bottom wall of the air storage chamber, so that this part of the air can leave the air storage chamber along the vent 5121 and exit from the port of the vent 5121. The glue drop 9 blown toward the top of the silencer sponge 7 can be blown away before the motor end cover 8 and the silencer sponge 7 are bonded together, so as to expand the glue area on the top of the silencer sponge 7 and improve the firmness of the bonding between the motor end cover 8 and the silencer sponge 7; after the electromagnet 643 is turned off, the compression spring will push the piston 513 and the magnetic part 514 upward, and the magnetic part 514 will apply a downward adsorption force to the motor end cover 8, so as to make the silencer sponge 7 abut against the motor end cover 8 and the groove wall of the feeding groove, thereby further improving the firmness of the bonding between the motor end cover 8 and the silencer sponge 7.

[0060] It should be noted that the electromagnet 643 on the material picking device 64 provided between the material collection assembly and the rotating table 5 can be set to be able to form a magnetic field that is attracted to the magnetic part 514, so as to avoid the situation where the magnetic field formed by the electromagnet 643 and the magnetic part 514 repel each other and cancel each other out, so that the magnetic field applied by the electromagnet 643 to the motor end cover 8 on the finished product is weak, resulting in the electromagnet 643 being unable to suck away the finished product. After the electromagnet 643 used to suck away the finished product is set to be able to form a magnetic field that is attracted to the magnetic part 514, since the electromagnet 643 can abut against the motor end cover 8, and there is always a certain distance between the magnetic part 514 and the motor end cover 8 due to the wall thickness of the silencer sponge 7 and the material receiving box 512, the electromagnet 643 can suck away the finished product more easily.

[0061] The implementation principle of the automatic bonding device for motor silencer sponge of the present application is as follows:

[0062] The utility model comprises a sponge feeding component 1, an end cover feeding component 2, a gluing device 3, a collecting device 4, a rotating table 5 and three groups of material moving components 6. A group of material moving components 6 is provided between the sponge feeding component 1, the end cover feeding component 2 and the collecting device 4 and the rotating table 5. A plurality of material receiving parts 51 are provided on the rotating table 5 and the material receiving parts 51 can be switched in the order of a feeding station, a gluing station, a bonding station and a unloading station. The sponge feeding component 1 can provide a muffler sponge 7 to a group of material moving components 6 corresponding thereto, so that the muffler sponge 7 can be moved to the material receiving part 51 located at the feeding station through the material moving component 6, and then the rotating table 5 will move the material receiving part 51 to the gluing station by rotating, so as to pass through the gluing device 3 sprays glue onto the silencer sponge 7, then the rotating table 5 moves the receiving piece 51 and the silencer sponge 7 sprayed with glue to the bonding station, at this time the material moving assembly 6 arranged between the end cover loading assembly 2 and the rotating table 5 moves the motor end cover 8 provided by the end cover loading assembly 2 onto the silencer sponge 7, so that the motor end cover 8 and the silencer sponge 7 are bonded to form a finished product, and finally the rotating table 5 moves the receiving piece 51 and the finished product to the unloading station, so that the finished product can be taken off the receiving piece 51 and moved into the gathering device 4 by the material moving assembly 6 arranged between the gathering device 4 and the rotating table 5, thereby realizing the automatic assembly of the silencer sponge 7 and the motor end cover 8, which greatly improves the assembly efficiency.
