[0039] like Figure 1-13 As shown, the present invention discloses an EVA foam assembly device suitable for a motor wind shield, comprising:

[0040] Rack 1;

[0041] A working platform 2, which is arranged above the frame 1, and a fixing portion 22 for placing a motor wind cover 24 is provided on a rotating disk 21 of the working platform 2;

[0042] The heating mechanism 3 is arranged on one side of the working platform 2 to heat the motor hood 24;

[0043] EVA conveying mechanism 4, which is arranged on one side of the working platform 2 and is used to provide EVA foam 47;

[0044] The transport mechanism 5 is placed above the frame 1 to transport the EVA foam 47 in the EVA conveying mechanism 4 to the motor wind cover 24 on the fixing part 22;

[0045] The loading and unloading mechanism 6 includes a loading assembly 61 and a unloading assembly 62 , and is disposed at two ends of the frame 1 .

[0046] The motor hood 24 is transported to the fixed part 22 by the loading component 61, and then the rotating disk 21 rotates, the pre-heating component 31 and the main heating component 32 heat the motor hood 24, and then the pressing mechanism 7 positions the motor hood 24, and the transporting mechanism 5 transports the EVA foam 47 on the EVA conveying mechanism 4 to the motor hood 24.

The heating bracket 321 is arranged on the fixed plate 23 of the inner ring of the working platform 2, the heating rod lifting cylinder 322 is arranged on one side of the heating bracket 321, and the heating rod 323 is arranged at the movable end of the heating cylinder, wherein the heating rod 323 controls the heating temperature through a temperature sensor, and sets the heating time to heat the motor hood 24. The heating rod lifting cylinder 322 is fixed on the heating bracket 321, and the movable end of the heating rod lifting cylinder 322 moves up and down to control the movement of the heating rod 323, so that the heating rod 323 is close to or away from the motor hood 24, so as to achieve the heating of the motor hood 24. The setting of the two heating components shortens the heating time and improves the heating efficiency.

[0048] like Figure 5 , 6As shown, the EVA conveying mechanism 4 includes a feeding tray 41, a winding shaft 42, a material placement platform 43, a material picking platform 44 and a pressure roller 45.
