[0068] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0069] This embodiment provides a polyimide film attaching device for separating the adhesive composite tape of the polyimide film and the isolation film, and then dividing the separated polyimide film into small pieces, and automatically attaching the divided small pieces of polyimide film to the surface of the product. Figure 1 and Figure 2 ,include:

[0070] Frame 10, used to fix and support various components;

[0071] The coil material feeding mechanism 20 is used to provide polyimide film feeding;

[0072] Specifically, the coil material feeding mechanism 20 includes a first material tray 21 rotatably mounted on the frame 10 , and the first material tray 21 is used for loading the composite coil material of the polyimide film and the isolation film.

[0073] Preferably, a polyimide film attaching device of this embodiment further includes a tensioning mechanism 22, which is used to tension the composite material strip of the polyimide film and the isolation film.

A second guide wheel 22 is rotatably provided on both sides above the first guide wheel 221. 3. The composite material strip of the polyimide film and the isolation membrane is elastically loaded in a V-shape on the second guide wheel 223 and the first guide wheel 221. In this embodiment, the composite material strip comes out of the first material tray 21, passes through the second guide wheel 223 on the left in sequence, then passes downward through the first guide wheel 221 and then passes upward through the second guide wheel 223 on the right. When the composite material strip is pulled, the first guide wheel 221 slides upward and the pulling spring 222 is in a stretched state. Under the elastic contraction action of the spring 222, the composite material strip is in a tensioned state.

[0074] Reference Figure 3 and Figure 4 The polyimide film attaching device of this embodiment further includes a film separation mechanism 30, which is used to separate the polyimide film and the isolation film and transport the polyimide film to a loading station;

[0075] In this embodiment, referring to Figure 5 The film separation mechanism 30 includes a guide plate 31 fixed on the frame 10. The upper surface of the guide plate 31 is provided with a guide groove 311 for guiding the composite material strip of the polyimide film and the isolation membrane. The length direction of the guide groove 311 is along the Y-axis direction. The composite material strip is loaded into the guide groove 311 downward from the second guide wheel 223 on the right.

[0076] It should be noted that in order to make the composite material strip stick to the guide groove 311, a third guide wheel 224 is rotatably installed on the frame 10. The lowest point of the circumferential guide surface of the third guide wheel 224 is flush with the upper surface of the guide plate 31.

[0077] Furthermore, in a polyimide film attaching device of this embodiment, an extrusion limiting mechanism 32 is also provided above the guide groove 311. The extrusion limiting mechanism 32 includes a pressure head 321 and a quick clamp 322 that pushes the pressure head 321 to press against the guide plate 31. When the composite material strip is loaded into the guide groove 311, the quick clamp 322 is pushed to press the pressure head 321 down to the upper surface of the guide plate 31 to prevent the composite material strip from escaping from the guide groove 311.

[0078] Preferably, in the polyimide film attaching device of this embodiment, the lower surface of the guide plate 31 is configured to be wedge-shaped, for guiding the isolation film to move to the isolation film winding mechanism 70, and the isolation film winding mechanism 70 is used to wind up the isolation film after being separated from the polyimide film.

[0079] Specifically, the isolation film winding mechanism 70 includes a second material tray 71 and a first servo motor 72. The first servo motor 72 is fixedly mounted on the frame 10, and the second material tray 71 is fixedly connected to the power output shaft of the first servo motor 72. The first servo motor 72 drives the second material tray 71 to rotate, thereby realizing active material winding of the isolation film and providing power for the composite material strip conveying.

[0080] Specifically, the isolation membrane is separated from the polyimide film, and the isolation membrane is bent downward along the wedge-shaped lower surface of the guide plate 31. A fourth guide wheel 73 is rotatably provided below the wedge-shaped lower surface to guide the isolation membrane to the second material tray 71, thereby achieving smooth collection of the isolation membrane.

[0081] The polyimide film attaching device of this embodiment further includes a rotating station 50, which is used to load the polyimide film and realize continuous loading of the polyimide film by rotating the station.

[0082] Reference Figure 6 The rotating station 50 includes a turntable 51 and a turntable support frame 52. The turntable support frame 52 is fixedly connected to the frame 10.

The second servo motor 53 is connected to the rotating shaft of the turntable 51 through a synchronous belt transmission mechanism. The second servo motor 53 is used to drive the turntable 51 to rotate. In this embodiment, the second servo motor 53 is used to drive the turntable 51 to rotate 180° each time. Two collinearly arranged clamping grooves 511 are provided on the turntable 51, which are alternately docked with the discharge port of the guide groove 311 to realize the alternating delivery of the polyimide film to the two clamping grooves 511.

The telescopic rod of the driving cylinder 42 is fixedly connected to a blade mounting block 43, and the blade mounting block 43 is slidably mounted on the frame 10 along the X-axis direction. A blade 41 is fixedly mounted on the blade mounting block 43, and the driving cylinder 42 drives the blade 41 to slide along the X-axis direction to cut the polyimide film.

[0085] During actual operation, the first servo motor 72 drives the second material tray to rotate and collect the material, driving the polyimide film into the clamping groove 511. When the length of the polyimide film entering the clamping groove 511 reaches the set length, the first servo motor 72 stops rotating, and drives the cylinder 42 to drive the blade 41 to slide along the X-axis direction to cut the polyimide film, and then drives the cylinder 42 back to the initial position. The second servo motor is used to drive the turntable 51 to rotate 180°, and another clamping groove 511 on the turntable 51 is docked with the guide groove 311 outlet, and the above action is repeated.

A bracket is installed on the slide of the slide cylinder, and a material sensor is fixedly installed on the bracket. The position of the material sensor is adjusted by the slide cylinder so that its transmitting end is aligned with the avoidance waist hole. When the polyimide film enters the clamping groove 511, after the material sensor detects the end of the polyimide film, the first servo motor 72 stops rotating and the blade 41 cuts the polyimide film.

The X-axis moving mechanism 61, the Y-axis moving mechanism 62, and the Z-axis moving mechanism 63 are used to drive the adsorption head 64 to move the polyimide film on the turntable 51 to the surface of the product to be attached.

[0089] Specifically, the X-axis moving mechanism 61 adopts a screw-nut translation mechanism, the nut of the screw-nut translation mechanism is fixedly connected to a mounting plate, and the mounting plate is slidably installed on the frame 10 along the X-axis through a guide rail slider mechanism.
