[0002] Protective films can be categorized by application, including electronic component protective films, automotive protective films, household protective films, and food preservation protective films. Electronic component protective films are widely used in the production of FPCs, PCBs, and electronic components to protect surface materials and prevent static electricity. During the production of protective films, a dryer is required to remove any adhering moisture.

The front and rear ends of the first guide roller 4 are rotatably connected to the first support plate 5 to support the first guide roller 4. The left end of the first support plate 5 is fixedly connected to the inner left side of the bracket 1.

[0021] In this embodiment, a second opening is provided on the inner right side and near the top of the support 1, and a first opening is provided on the inner left side and near the bottom of the support 1. The lower end of the membrane 3 bends to the left and slides through the first opening, and the upper end of the membrane 3 bends to the right and slides through the second opening. The lower end of the first guide roller 4 and the upper end of the second guide roller 9 abut against the membrane 3 respectively.

[0022] In this embodiment, connecting blocks 6 are fixedly connected to the inner left and right sides of the bracket 1 near the middle position for installing and connecting heating tubes 7. Heating tubes 7 are fixedly connected to the side of the connecting blocks 6 near the membrane 3 for drying the membrane 3. Heating wires are fixedly embedded in the heating tubes 7 for heating the heating tubes 7. Temperature sensors 8 are fixedly embedded in the side of the connecting blocks 6 near the heating tubes 7 for monitoring the temperature. The temperature sensor 8 is a PT100. Controller 2 is fixedly connected to the inner side wall of the bracket 1 near the top position for controlling the start and stop of the heating wires. Controller 2 is an 80S51. The input terminal of controller 2 is electrically connected to the output terminal of temperature sensor 8, and the output terminal of controller 2 is electrically connected to the input terminal of heating wires.

[0023] In this embodiment, a fixing plate 16 is fixedly connected to the inner right side of the bracket 1 to support the first spring 15. The fixing plate 16 is located below the connecting block 6. Triangular reinforcing blocks are fixedly connected to both the upper and lower sides of the fixing plate 16. The right end of the reinforcing block is fixedly connected to the inner right side wall of the bracket 1. A support block 11 is provided at the upper end of the fixing plate 16 to support the vibrating wheel 13. A second spring 17 is fixedly connected between the right end of the support block 11 and the inner right side wall of the bracket 1 to provide elastic support for the support block 11. Multiple rubber columns 14 are fixedly connected between the lower end of the support block 11 and the fixing plate 16 to provide elastic support for the support block 11. The first spring 15 is slidably sleeved on the rubber column 14 to provide elastic support for the support block 11. The two ends of the first spring 15 are fixedly connected to the lower end of the support block 11 and the upper end of the fixing plate 16, respectively.

[0024] In this embodiment, the support block 11 is provided with a storage groove, and a vibration motor 12 is fixedly connected to the bottom of the storage groove to drive the support block 11 and the vibration wheel 13 to vibrate. The vibration motor 12 is model YZS-1.5-2. The support block 11 is provided with a groove at one end near the membrane 3. The vibration wheel 13 is rolled in the groove to drive the membrane 3 to shake.

The left side of the vibration wheel 13 passes through the groove and abuts against the membrane 3.

[0025] In this embodiment, the film 3 is first passed through the first opening, then placed below the first guide roller 4, then pulled upwards and placed above the second guide roller 9, then passed through the second opening, and finally connected to the external winding equipment. The driving force of the winding equipment drives the film 3 to move continuously. At the same time, the heating wire is activated to heat the heating tube 7, and the film 3 is dried through the heating tube 7. The temperature sensor 8 monitors the temperature in real time. Once the temperature exceeds the preset range, it sends a signal to the controller 2, which shuts off the heating wire. When the temperature is lower than the preset value, the heating wire is turned on, thereby achieving temperature control. In addition, the vibration motor 12 drives the support block 11 and the vibration wheel 13 to vibrate, thereby causing the film 3 to shake, effectively promoting the dripping and removal of moisture on the film, and significantly improving the drying efficiency.
