[embodiment]:
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Preferred embodiment: please refer to Fig. 1, Fig. 2, be the internal structure schematic diagram of the utility model FPC bar folder, comprise reverse drive gear, propulsion system, folding arm device, worktable.Propulsion system 15 adopt an electromagnetic adjustable speed motor, reverse drive gear comprises a dial 13, mutually first gear 8, second gear 10 of interlock and be fixed on first shift fork 9 on first gear, be fixed on second shift fork 11 on second gear also have an action output shaft 7.Dial directly is connected in the rotating shaft of motor, dial is provided with a finger 12, the rotation drive finger of motor is stirred the shift fork on one of them gear, this shift fork drives two gear retrograde rotations, after finger turns to certain angle, separate with the preceding once shift fork of contact, contact driven gear opposite spin again with shift fork on another gear.So action, circulation has repeatedly realized that continuous, unidirectional rotation with motor changes the action of turning back in the certain angle scope into.Its principle is as follows: as Fig. 5-1,5-2, four diagrams of 5-3,5-4 is that finger moves a week under the drive of motor, and output shaft is realized the process that 180 degree are turned back and moved.The angle of tested flexible circuit board such as common cellular phone flip can not reach 180 degree, can realize turning back at any angle by the length that changes shift fork.Shown in Fig. 6-1,6-2,6-3,6-4, we have changed second group of 11 length again, the position of finger 12 in shown in the diagram 6-3 just can be separated with second shift fork 11, this moment, first shift fork 9 did not run to the position as level among Fig. 5-3, thereby the actual angle A of turning back that obtains is spending less than 180 like that shown in the diagram.The length that we equally also can change the length of first shift fork or change two shift forks simultaneously adapts to the correct angle A of turning back of cellular phone flip.
The folding arm device has dual mode, and first kind comprises folding arm rotating disk 6 and two folding arms: first folding arm 5 and second folding arm 4, folding arm is installed on the rotating disk, follows rotating disk and does the reciprocating and turning-back action.Folding arm can be made different length, to be suitable for simultaneously several mobile phones being bent experiment.Two folding arms certain angle of on rotating disk, being separated by, renovating of mobile phone is between two folding arms during test, and the reciprocating and turning-back of two folding arms has just been realized the action of turning back of cellular phone flip, is the actual test mode of using of simulation; Another kind has only first folding arm 5, and cellular phone flip and folding arm bundle during use, does the reciprocating and turning-back action with folding arm, is a kind of method of testing comparatively stably.
This example also is provided with a cover body, and reverse drive gear and power setting part are covered, and impulse meter, start button, count button is set on the cover body, is used to control the control device of motor: speed regulator.What be connected with impulse meter is one and is installed on the dial 13 near the sensor of switch near switch that the corresponding fixed installation with it of detector is used for monitoring the number of turns that motor rotates, result under the counter records.There is the knob can be on the speed regulator by regulating the frequency that motor speed is regulated bending.
Use test process of the present utility model as follows:
Mobile phone 2 relative fixed ends to be tested are positioned on the worktable 1, and the folding axle center of cellular phone flip is relative with the axis of rotation of folding arm rotating disk 6 as far as possible, with belt mobile phone relative fixed end is fixed.Mobile phone relative motion end is that the front end of cellular phone flip is pasted a thin slice 3, can select polaroid for use, and first folding arm 4 is opened cellular phone flip by stirring thin slice 3.
Behind the power connection, press start button, equipment is started working, and presses count button, the number of times of opening entry bending.After start button was pressed, motor 15 was started working, and drove dial 13 and did clockwise rotation.Finger 12 malleations that dial 13 is installed above are on second shift fork 11, and shift fork 11 is fixedly mounted on second gear 10, does clockwise rotation together at the drive lower gear 10 of finger 12.Second gear 10 and the 8 mutual interlocks of first gear drive first gear 8 and do counterclockwise rotation, and first shift fork 9 is installed on first gear 8, so shift fork 9 can be followed gear 8 and done counterclockwise rotation.First gear 8 is consolidated with output shaft 7, drives output shaft 7 this moment and does and be rotated counterclockwise.Folding arm rotating disk 6 is installed on the output shaft 7, and second folding arm 4 and first folding arm 5 are installed on the folding arm rotating disk 6, and they are followed output shaft 7 together and do and be rotated counterclockwise.Like this, second folding arm 4 can be stirred thin slice 3 when being rotated counterclockwise, just can raise renovating of mobile phone.After the driven by motor dial rotates through certain angle, as shown in Figure 3, finger 12 can separate with it after second shift fork 11 rotates through certain angle, then can push first shift fork 9, driving first shift fork 9, first gear 8, action output shaft 7, folding arm rotating disk 6, first folding arm 5 and second folding arm 4 etc. oppositely promptly turns clockwise, cause first folding arm 5 so just can be stirred and renovate the position that makes it and get back to closure below cellular phone flip.When first gear 8 is done reverse rotation, drive second gear 10 again, first folding arm 5 is brought back to initial position.Be installed in the back of dial 13 near the sensor of switch 14, the every rotation of dial once all can be sent to the signal that detects above the counter near the detector of switch, and counter just can write down once.It more than is motor rotation one week and realizing with cellular phone flip bending action overall process once.
Fig. 1 and bending method shown in Figure 3 also are the actual method of testings of using of simulation.Cellular phone flip can rely on elastic force to automatically spring open after opening certain angle, also can rely on the elastic force auto-closing; In order to simulate this effect, the utility model can be controlled the amplitude of bending by the length of shift fork, can control its operation orientation at the whole story by the installation site of setting up two folding arms.Specific practice be folding arm 5 run to renovate can rely on elastic force to flick in, set up its be the operation last position, and second folding arm 4 will with being installed separately that first folding arm 5 is tried one's best, principle is that worktable can not run in the last position of second folding arm 4.Renovate like this flick or closed in, be unlikely to because its speed is faster and forereach folding arm than the speed of folding arm.So just can simulate actual making is used for FPC is carried out the test of science more.
The utility model also can be tested comparatively stably to FPC.As Fig. 4, a folding arm only is installed on the folding arm rotating disk, cellular phone flip is bundled on the folding arm, follows folding arm and does the bending motion.Comparatively steady because of the action of folding arm, there is not percussive action, be a kind of method of testing comparatively stably therefore.That worktable and folding arm can be done is very long, to be applicable to simultaneously several mobile phones is tested.
The principle that the utility model bar folder adopts is that the continuous running with motor is converted to the reciprocating and turning-back motion, therefore has high stability and reliability.
