The release paper is also called silicone paper or anti-stick paper. The release paper can also be other sheet-like materials that have the same isolation and protective adhesive layer (this application only uses release paper as an example). The end of the adhesive-backed strip noise reduction component 50 of the present invention is the head end 50A.

[0027] As attached Figures 1 to 9As shown, the application discloses a release paper separating device 1 of a tape-shaped noise reduction element with adhesive, which comprises a mounting plate 10, a fixing assembly 20, a first separating assembly 30 and a second separating assembly 40 arranged on the mounting plate 10; wherein the fixing assembly 20 comprises a fixing element 21 and a connecting plate 22, the first separating assembly 30 comprises a first driving source 31 and a pressing element 32 connected with the first driving source 31, and the second separating assembly 40 comprises a second driving source 41 and a peeling element 42 connected with the second driving source 41; the pressing element 32 is arranged on one side of the fixing element 21, and the peeling element 42 is arranged on the opposite side of a working end 211 of the fixing element 21. Figure 7 As shown, the first end 50A of the tape-shaped noise reduction element 50 is fixed by the fixing assembly 20, and optionally, the first end 50A of the tape-shaped noise reduction element 50 arranged with the release paper 53 on one side is fixed by the peeling element 42 in the second separating assembly 40, and then the first end 50A of the tape-shaped noise reduction element 50 is pressed by the pressing element 32 in the first separating assembly 30 to separate the release paper 53 from the adhesive layer, and then the release paper 53 is completely peeled from the adhesive layer by the peeling element 42 in the second separating assembly 40. Figure 7 That is, the release paper separating device 1 of the tape-shaped noise reduction element with adhesive can automatically and conveniently separate the release paper 53 from the adhesive layer from the end.

[0028] Optionally, the fixing assembly 20 can be any combination of a power source (with a certain pressure) or a gas cylinder or a motor as a power source and a mechanical claw or a mechanical clamp or a vacuum suction cup or a needle suction cup as a fixing element, and the second separating assembly 40 can also be any combination of a gas cylinder or a motor as a power source and a mechanical claw or a mechanical clamp or a vacuum suction cup or a needle suction cup as a peeling element.

[0029] As an embodiment, the fixing assembly 20 adopts a gas source (not shown) and a needle suction cup combination, the first separating assembly 30 adopts a gas cylinder and a needle combination, and the second separating assembly 40 adopts a gas cylinder and a vacuum suction cup combination to illustrate the working principle of the application.

[0030] In order to save the space occupied by the first separating assembly, the first separating assembly 30 is arranged on the second separating assembly 40. Figure 8 Figure 9 ​As shown, the first separating assembly 30 of the present application further comprises a fixing plate 34 connected with the mounting plate 10, a third cylinder 33 arranged on the fixing plate 34, and a baffle 35 connected with the driving end 331 of the third cylinder 33; the first driving cylinder 31 (i.e. the first driving source) and the pressing element 32 are arranged on one side of the baffle 35, and the first cylinder 31 can drive the pressing element 32 to swing relative to the baffle 35. Therefore, in use, the driving end 331 of the third cylinder 33 can be driven to drive the baffle 35 to extend, so as to position the first end 50A of the adhesive tape-shaped noise reduction element 50 at a predetermined position, and then the first driving cylinder 31 can be driven to drive the pressing element 32 to press the end of the tape-shaped noise reduction element 50 close to the edge of the release paper 53, so as to preliminarily separate the release paper 53 at the first end 50A from the adhesive layer.

[0031] Preferably, the pressing element 32 of the present application comprises a swing plate 321 connected with the first cylinder 31, the swing plate 321 is swingably connected with the baffle 35, and the swing plate 321 is provided with a pressing structure, which in the present embodiment is a plurality of pressing pins 322. The pressing structure can also be other structures, such as a sheet shape, a tooth shape, etc. Then, the swing plate 321 drives the pressing pins 322 to swing relative to the baffle 35, so as to press the end of the tape-shaped noise reduction element 50 close to the edge of the release paper 53, so as to preliminarily separate the release paper 53 at the first end 50A from the adhesive layer (as shown in Figure 7

[0032] The second separating assembly 40 of the present application further comprises a first swing arm 43, and the peeling element 42 can be a plurality of vacuum suction cups; one end 431 of the first swing arm 43 is rotatably arranged on the mounting plate 10 through a rotating shaft 44, the driving end 411 of the second driving source 41 is connected with the first swing arm 43, the other end 432 of the first swing arm 43 is provided with a branch support 45, and the vacuum suction cups 42 are arranged on the branch support 45. The vacuum suction cups 42 are arranged on the opposite side of the working end 211 of the needle type suction cup 21. Therefore, after the first end 50A of the tape-shaped noise reduction element 50 is preliminarily separated from the adhesive layer by the first separating assembly 30 (as shown in Figure 7 Figure 2 Figure 3 the action process), the release paper 53 is peeled off from the tape-shaped noise reduction element 50.

[0033] ​​​Furthermore, to prevent incomplete separation of the release paper and adhesive layer at the first end 50A due to insufficient pressure from the top-pressing structure, the present invention can optionally further include a second swing arm 46 and a second swing arm cylinder 47 in the second separation assembly 40. One end 461 of the second swing arm 46 is connected to the drive end 471 of the second swing arm cylinder 47, and the other end 462 of the second swing arm 46 is connected to the branch bracket 45.
