[0028] As a preferred embodiment, a positioning groove 5 matching the plastic part is installed on the conveyor belt 204, and the plastic part is placed in the positioning groove 5 to prevent the plastic part from being shifted during transportation.

[0029] As a preferred embodiment, one end of the active roller 202 and both ends of the driven roller 203 are connected to the inner wall of the base 1 through bearings.

[0030] It is worth noting that the hot melt assembly 3 includes a gantry 301, on which a first cylinder 302 is installed. The piston rod of the first cylinder 302 is connected to a mounting plate 303, on which a heating plate 304 is installed to heat and melt the position where the plastic part is connected to the silencer paper.

[0031] As a preferred method, the assembly component 4 includes a fixed ear 401 for fixing the base 1, and the top of the fixed ear 401 is connected to a rotating column 403 through a support bearing 402, and a gear ring 404 is fixed on the rotating column 403, and the gear ring 404 is meshed with a rack 405, and the rack 405 is connected to an electric telescopic rod 406, and the electric telescopic rod 406 is installed on one side of the base 1, and a rotating plate 407 is fixedly connected to the top of the rotating column 403, and a second cylinder 408 is installed at the end position of the rotating plate 407, and the piston rod of the second cylinder 408 is connected to a pressure block 409, and the bottom of the pressure block 409 is installed with evenly distributed vacuum suction cups 410, and the vacuum suction cups 410 are connected to a vacuum pump through a vacuum tube. The assembly component 4 can stick the silencer paper to the hot melt position of the plastic part and press the silencer paper so that the silencer paper and the plastic part are more fitted, which is beneficial to the connection between the plastic part and the silencer paper.

[0032] As a preferred embodiment, a positioning slot 6 is provided on one side of the base 1 at a position corresponding to the rack 405 , and the positioning slot 6 is slidably connected to the rack 405 via a positioning slider, further ensuring the accuracy of the displacement path of the rack 405 .

[0033] Among them, the driving motor 201, the first cylinder 302, the heating plate 304, the electric telescopic rod 406, and the second cylinder 408 are existing technologies and will not be described in detail; at the same time, this application also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0034] Working principle and process: Place the plastic part in the positioning groove 5, and the side that needs to be connected to the silencer paper is at the top position, start the driving motor 201 of the conveying platform 2, and then the active roller 202 drives the conveyor belt 204 and the driven roller 203 to rotate, and the plastic part can be conveyed to the position of the hot melt component 3. At this time, the plastic part is under the heating plate 304. Start the heating plate 304 to make its temperature reach a suitable range, start the first cylinder 302 of the hot melt component 3, and then the first cylinder 302 extends, and the mounting plate 303 drives the heating plate 304 to move downward until the heating plate 304 contacts the plastic part to heat and melt the position where the plastic part is connected to the silencer paper. Then, start the driving motor 201 of the conveying platform 2 again to convey the plastic part to the assembly component 4 position, where the vacuum suction cup 410 of the assembly component 4 will remove the silencer paper. After the sound paper is adsorbed, the electric telescopic rod 406 is started, and then the rack 405 moves to cause the gear ring 404 to rotate, which can rotate the rotating column 403 and the rotating plate 407, so that the pressure block 409 and the sound-absorbing paper adsorbed by it are located above the plastic part, and the second cylinder 408 is started, and then the second cylinder 408 is extended, so that the sound-absorbing paper and the pressure block 409 move downward until the sound-absorbing paper is pressed on the melting position on the top of the plastic part. The pressure block 409 applies pressure on the sound-absorbing paper, which can make the sound-absorbing paper fit the plastic part more closely. The vacuum pump of the vacuum suction cup 410 is turned off, and the second cylinder 408 is contracted, and the assembled plastic part and the sound-absorbing paper can be removed. Compared with the traditional sound-absorbing paper with adhesive backing to connect the plastic part, the hot melt method improves the connection strength between the sound-absorbing paper and the plastic part, makes the sound-absorbing paper not easy to fall off, and eliminates the glue, thereby reducing the raw material cost of production.
