When the fourth cylinder 232 drives the third ACF pressing part 236 to move toward the ACF push rod 237, the third head approaches the ACF push rod 237 and then contacts it, pushing the ACF push rod 237 to move toward the first limiting part 2372 and compressing the elastic part 2371, and then its lower end abuts against the first limiting part 2372. When the fourth cylinder 232 drives the third ACF pressing member 236 to reset upward, the ACF push rod 237 is reset by the elastic member 2371; the fourth ACF pressing member 238 is provided with a fourth head, and the fourth ACF fixing member is provided with a fourth groove area, and the fifth cylinder 233 drives the fourth ACF pressing member 238 to move in the direction of the fourth ACF fixing member so that the fourth head is pressed against the fourth groove area.

[0033] The ACF passes through the first ACF pressing member 215 and the first ACF fixing member 216, the second ACF pressing member 223 and the second ACF fixing member 224, the third ACF pressing member 236 and the ACF push rod 237, and the fourth ACF pressing member 238 and the fourth ACF fixing member in sequence; in the initial state, they are all away from each other, and only the third cylinder 222 is controlled to drive the second ACF pressing member 223 to press the ACF onto the second ACF fixing member 224, and the first linear module 211 is controlled to drive the second stretching part 22 as a whole to move toward the ACF. The first pulling part 212 moves in the moving direction. At this time, the first pulling part and the third pulling part are both in the ACF release state. Then, the first linear module 211 drives the second stretching part 22 to move the set length, which can drive the ACF to move the set length. In other words, the new ACF is passed from the ACF feeding side of the pressure head assembly to the ACF discharging side through the set length, so as to realize the fixed length feeding of the ACF, so as to ensure that the ACF length provided to the module meets the requirements; after the delay is set for a certain period of time, the first ACF pressing part 215 is driven to press against the first ACF fixing part 216 by controlling the second cylinder 214. Subsequently, the third cylinder 222 drives the second ACF pressing member 223 away from the second ACF fixing member 224 to release the ACF, the fourth cylinder 232 drives the third ACF pressing member 236 to press against the ACF push rod 237, and the fifth cylinder 233 drives the fourth ACF pressing member 238 to press against the fourth ACF fixing member. Since the first pulling part and the third pulling part are located at both ends of the inlet and outlet of the second pulling part, the actions of the two will clamp the ACF at this time. Since the fourth cylinder 232 drives the third ACF pressing member 236 to move downward toward the ACF push rod 237, the ACF will be moved downward together. At the same time, due to the restriction of the second guide wheel 234 on the ACF, the ACF will be tightened in the process of the third ACF pressing member 236 pushing the ACF push rod 237 downward, and then the first linear module 211 drives the second stretching part 22 to return to the initial position, and a fixed-length cycle ends.
