[0002] PET substrate, or polyethylene terephthalate substrate, plays a crucial role in many fields. It possesses excellent physicochemical properties, such as high mechanical strength, ensuring shape stability during processing and use and resisting deformation. Its excellent electrical insulation properties effectively prevent current leakage, making it an ideal material for manufacturing flexible circuit boards, touch screens, and other electronic products. In the PET substrate processing, the feeding stage is critical, directly impacting the efficiency, quality, and consistency of the entire process. Precise and efficient feeding is fundamental to ensuring the smooth operation of subsequent processing steps.

[0023] The working principle of this utility model is as follows:

[0024] When feeding PET substrates, the box door 3 is opened, and the PET substrates are placed on top of the stacking plate 42. Then, the box door 3 is closed. Next, the microcontroller 11 controls the operation of motor 411. The output shaft of motor 411 drives quarter gear 419 to rotate. The rotation of quarter gear 419, through meshing gear 418, causes gear 418 to rotate 360 ​​degrees, which in turn drives lead screw 412 to rotate 360 ​​degrees. The rotation of lead screw 412, through the threaded internal cylinder 413, moves the stacking plate 42 upwards, thereby moving the PET substrates upwards. The distance sensor 12 monitors the distance to the uppermost surface of the PET substrate in real time and transmits the detection data to the microcontroller 11. The microcontroller 11 integrates the information. When the uppermost PET substrate moves to the inner surface of the discharge port 5, the electric push rod 41... 4. Operation: The telescopic end of the electric push rod 414 pushes the sliding box 43 to move towards each other from inside the protective shell 10, thereby driving the roller 44 to clamp the front and rear ends of the PET substrate neatly. Then, the second motor 415 operates, and the output shaft of the second motor 415 drives the first quarter gear 416 to rotate. The first quarter gear 416 drives the rotating shaft 45 to rotate through the meshing gear 417. The first quarter gear 416 rotates 90 degrees, which drives the first gear 417 to rotate 360 ​​degrees, thereby driving the rotating shaft 45 to rotate 360 ​​degrees. Then, through the support block 46, the surface of the dial wheel 47 contacts the PET substrate, and at the same time, it drives the PET substrate to move to the right. The PET substrate is fed through the discharge port 5 and the guide plate 6. The PET substrate falls onto the upper end of the conveyor belt 7. Then, through the control of the microcontroller 11, the third motor 8 operates, and the output shaft of the third motor 8 drives the right-side rotating column to rotate, thereby driving the PET substrate to be transported through the conveyor belt 7.

[0025] It is worth noting that in the above embodiments, the motor 411, motor 415, electric actuator 414, motor 8, and distance sensor 12 can all be YS8024, the electric actuator 414 can be DYTZ, and the distance sensor 12 can be UNDDK30U6113 / S14.
