Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
As shown in fig. 1 to 7, the processing method of the FFC with variable conductor section comprises the following steps:
A. and (3) feeding: placing the conductor end on the calendaring aisle 3 between the first calendaring wheel 1 and the second calendaring wheel 2, and keeping the conductor vertical to both the first calendaring wheel 1 and the second calendaring wheel 2; the first calender wheel 1 and the second calender wheel 2 have a certain initial distance between them, so that the calender aisles 3 are kept at a distance of the desired conductor end working thickness. In the present embodiment, the end of the processed conductor is flat, so that the rolling passage 3 is relatively narrow, and the rolled thickness of the processed conductor is small.
B. Calendering: starting a calendaring wheel driving mechanism 4 for driving the first calendaring wheel 1 and the second calendaring wheel 2, so that the first calendaring wheel 1 and the second calendaring wheel 2 rotate reversely at the same speed, and calendaring the conductor; when the calendaring wheel driving mechanism 4 is started, the two calendaring wheels are driven to reversely rotate, and the conductor is transported from one side of the two to the other side of the two, and calendaring is performed simultaneously.
C. And (3) adjusting the distance: the first calendaring wheel 1 is moved by the calendaring adjusting mechanism 5 to adjust the width of the calendaring passageway 3, thereby changing the thickness of the conductor calendars, and the steps can be repeated when needed to be adjusted again; after the end of the conductor is processed, the thickness of the conductor needs to be increased when the middle of the conductor is processed, and even the conductor is pressed into an approximately circular elliptical shape, so that the distance between adjacent conductors in the FFC flexible flat cable is reduced, and short circuits are avoided. It is therefore necessary to move the first calender wheel 1 away from the second calender wheel 2 without interrupting the calendering operation, and after the movement is completed, the distance of the calendering aisle 3 increases and the thickness of the conductor obtained by calendering increases. Similarly, when the conductor is processed to the other end, the distance between the calendaring channels 3 needs to be reduced so that the end of the conductor is processed into a flat shape, and similarly, the first calendaring wheel 1 is only required to be close to the second calendaring wheel 2 to a required position.
D. Taking: the calender wheel drive mechanism 4 is turned off and the conductor is taken out.
As shown in fig. 4, the conductors in the conventional FFC are flat and closely arranged. While as shown in fig. 5, the thickness of the conductor in this embodiment is increased when the middle part of the conductor is rolled, so that the middle part of the rolled conductor is approximately circular (actually approximately elliptical), as shown in fig. 6, it can be intuitively seen that the same FFC is used for producing the same number of conductors, and the conductor spacing in this embodiment is greatly increased, so that the occurrence of short circuit is greatly avoided.
Specifically, the first calender wheel 1 and the second calender wheel 2 are disposed on the bracket 6, and the calender adjusting mechanism 5 includes a calender wheel moving structure 7 which is disposed on the bracket 6 and can drive the first calender wheel 1 away from or close to the second calender wheel 2. The rolling wheel moving structure 7 comprises a first wheel frame 8 arranged on the bracket 6 in a sliding manner and a transmission assembly 11 arranged on the first wheel frame 8, wherein the first rolling wheel 1 is axially and rotatably arranged on the first wheel frame 8, and the first wheel frame 8 is provided with a first telescopic rod 9 and a second telescopic rod 10 which are parallel to each other. The first wheel frame 8 is lifted, so that the first calendaring wheel 1 is lifted, and the lifting action is completed by means of the extension and compression of the first telescopic rod 9 and the second telescopic rod 10.
Further, the transmission assembly 11 includes a first worm wheel 12 fixed to the upper end of the first telescopic link 9 and a first worm 13 engaged with the first worm wheel 12, and the transmission assembly 11 further includes a second worm wheel 14 fixed to the upper end of the second telescopic link 10 and a second worm 15 engaged with the second worm wheel 14. The first worm 13 and the second worm 15 are hollow and are positioned on the same axis, the middle parts of the first worm 13 and the second worm 15 axially penetrate through the same connecting shaft 16, and the outer wall of the connecting shaft 16 is connected with the inner wall of the second worm 15 in a key way, so that the second worm 15 can be directly driven to rotate by the rotation of the connecting shaft 16, and the second worm wheel 14 is driven to rotate by the rotation of the connecting shaft 16.
It is emphasized that the outer wall of the connecting shaft 16 is slidably connected with the inner wall of the first worm 13, so that the connecting shaft 16 cannot directly drive the first worm 13 to rotate when rotating, two ends of the connecting shaft 16 extend out of the outer ends of the first worm 13 and the second worm 15 respectively, and the end of the connecting shaft 16 located at one side of the first worm 13 is provided with a locking structure 17 for fixing the first worm 13 and the connecting shaft 16 circumferentially. Only after the first worm 13 and the connecting shaft 16 are fixed by the locking structure 17, the connecting shaft 16 can rotate to drive the first worm 13 to rotate. The connecting shaft 16 is positioned at one end of the second worm 15, and a worm driving motor 18 for driving the connecting shaft 16 to rotate circumferentially is arranged at the end.
In combination with the above difference in the sliding connection between the connecting shaft 16 and the first worm 13 and the key connection between the second worm 15, as well, the first telescopic link 9 and the second telescopic link 10 in this embodiment are not necessarily telescopic synchronously. The first telescopic rod 9 and the second telescopic rod 10 can be independently telescopic. The first telescopic rod 9 comprises a first fixed rod 19 with one end fixed on the outer wall of the first wheel frame 8 and a first rotating rod 20 in threaded connection with the first fixed rod 19, and the other end part of the first rotating rod 20 is penetrated and arranged at the axle center of the first worm wheel 12 and fixed; the second telescopic rod 10 comprises a second fixed rod 21 with one end fixed on the outer wall of the first wheel frame 8 and a second rotating rod 22 in threaded connection with the second fixed rod 21, and the other end of the second rotating rod 22 is penetrated and arranged at the axle center of the second worm wheel 14 and fixed.
Therefore, according to the above transmission assembly 11, it can be obtained that the worm driving motor 18 directly drives the connecting shaft 16 to rotate, and the connecting shaft 16 directly drives the second worm 15 to rotate and finally drives the second worm wheel 14 to rotate, so that the second telescopic rod 10 stretches and contracts, and the first wheel carrier 8 on the side where the second telescopic rod 10 is located is lifted. Therefore, only after the connecting shaft 16 and the first worm 13 are fixed by the locking structure 17, the worm driving motor 18 can synchronously extend and retract the first telescopic rod 9 and the second telescopic rod 10 at the same time, and finally the first wheel frame 8 can be stably lifted.
Still further, the locking structure 17 includes a disc assembly 23 disposed at an end portion of the connecting shaft 16 at a side where the first worm 13 is located, the inner side of the disc assembly 23 is fixed to the end portion of the first worm 13, and a locking nut 24 screwed on the connecting shaft 16 is disposed on the outer side of the disc assembly 23 to lock the disc assembly 23 on the connecting shaft 16. The disc assembly 23 is slidably arranged on the connecting shaft 16, an inner disc 25 fixed with the outer end of the first worm 13, and an outer disc 26 arranged outside the inner disc 25 and bonded with the connecting shaft 16, and the locking nut 24 is in threaded connection with the outer side of the outer disc 26. Therefore, the inner disc 25 directly controls the first worm 13, and when the inner disc 25 rotates, the first worm 13 can be directly driven to rotate, and the first worm wheel 12 is driven to rotate, so that the first telescopic rod 9 stretches and contracts, and the first telescopic rod 9 and the second telescopic rod 10 stretch and contract independently, so that synchronization can be performed only after the connecting shaft 16 and the first worm 13 are fixed by the locking structure 17.
The outer disc 26 is connected with the connecting shaft 16 in a key way, so that the connecting shaft 16 can be directly driven to rotate by rotating the outer disc 26, the outer disc 26 can be manually rotated, and the outer disc 26 can be manually finely adjusted unlike the electric motor of the worm drive motor 18. Especially before the feeding step, the device is pre-adjusted, the characteristics of the first telescopic rod 9 are directly controlled by matching with the inner circular disc 25, and before the device is started, the expansion and contraction of the first telescopic rod 9 are firstly adjusted through the inner circular disc 25, so that the first wheel frame 8 can be kept parallel to the second calendaring wheel 2, the calendaring process is ensured to be more stable, more importantly, the thickness of a rolled conductor is ensured to be uniform, and the rolled conductor is not easy to deviate in the calendaring process.
After the parallelism is regulated by the inner circular sheet 25, the locking nut 24 is screwed down, so that the inner circular sheet 25, the outer circular sheet 26 and the connecting shaft 16 are locked and fixed. At this time, the outer disc 26 is rotated to simultaneously control the first telescopic rod 9 and the second telescopic rod 10 to synchronously extend and retract, and the first calender wheel 1 is controlled to lift and lower in a state of being kept parallel to the second calender wheel 2, so that the thickness of the conductor processing is adjusted.
In the present embodiment, the first calender wheel 1 and the second calender wheel 2 are hollow inside and the outer ends of the first calender wheel 1 and the second calender wheel 2 are respectively provided with a water-cooling reflux device 27. All be connected with inlet tube and outlet pipe with every calender wheel, and the inside cavity of calender wheel has the water-cooling chamber, and cold water gets into the water-cooling chamber from the inlet tube to discharge from the outlet pipe and form the water-cooling circulation, reduce the temperature of calender wheel, can accelerate conductor calender shaping and improve conductor stability. The calender wheel drive mechanism 4 comprises a motor 28 connected to the first calender wheel 1 and the second calender wheel 2, said motor 28 having a gearbox 29, a displaceable output shaft 30 of said gearbox 29 being fixed and coaxially rotatable with the first calender wheel 1.
Working principle: firstly, presetting, loosening a locking nut 24, adjusting an inner circular sheet 25 to control the expansion and contraction of a first expansion link 9 so as to lift a first wheel frame 8 at the side, and enabling the first calendaring wheel 1 and the second calendaring wheel 2 to be parallel; then, the lock nut 24 is screwed down to fix the inner disc and the outer disc with the connecting shaft, at the moment, the disc assembly 23 is manually adjusted, the first telescopic rod 9 and the second telescopic rod 10 are controlled to synchronously extend and retract, the lifting of the first calendaring wheel 1 is controlled to enable the distance between the first calendaring wheel 1 and the second calendaring wheel 2 to reach the initial distance, the motor 28 is started, and the first calendaring wheel 1 and the second calendaring wheel 2 reversely and synchronously rotate to conduct calendaring; after the conductor end part is processed, when the distance between the conductor rolling wheels needs to be increased, a worm driving motor 18 is started to drive a first worm 3 and a second worm 16 to synchronously rotate, and drive a first telescopic rod 9 and a second telescopic rod 10 to synchronously stretch, and finally the first rolling wheel 1 is lifted to a required height, so that the thickness of conductor rolling is increased, and the thickness of conductor rolling is reduced again when the conductor rolling wheel is processed to the other end part in the same way.
