The working process and principle of the stripping device for the protective adhesive tape 20 of the printed circuit board 19 are as follows:
firstly, the vertical positions of the roller b7-4 and the roller a12 are adjusted according to the thickness of the printed circuit board 19, so that the distance between the roller b7-4 and the roller a12 and a transmission line is slightly larger than the thickness of the circuit board, and the printed circuit board 19 can pass through and cannot jump in the peeling process of the adhesive tape 20. The mode of adjusting the roller b7-4 is as follows: rotating a back wave hand wheel 7-7 to drive a worm 7-5 to rotate at the moment, wherein the worm 7-5 is meshed with a worm wheel 7-8, a gear 7-10 is meshed with a rack 7-12, the rack 7-12 is driven to move up and down by the rotation of the worm 7-5, the rack 7-12 drives a sliding plate 7-3 to move up and down, a roller b7-4 is fixed at the bottom of the sliding plate 7-3, and the roller b7-4 is adjusted to be at a proper position by rotating the back wave hand wheel 7-7; the mode of adjusting the roller a12 is as follows: the roller a12 is fastened with a nut when it is moved to the proper position on the track c.
The position of the stripping needle 9-1 is adjusted, the number of the adjusting needles 9-1 is the same as that of the adhesive tapes 20, the interval between the adjusting needles 9-1 is the same as that between the adhesive tapes 20, and the adjusting grooves 9-2 are used for determining that the intervals are the same and then the stripping needles are screwed down by nuts.
The board feeding is started, the tape 20 of the printed circuit board 19 is put forward on the board feeding conveyor 3 on the forward side, and the board feeding conveyor 3 conveys the printed circuit board 19 to the actuator conveyor 5, i.e., into the actuator 4.
The printed circuit board 19 is transferred to the actuator 4 and then subjected to an alignment operation: at the moment, the direct current motor a4-9 works to drive the crank slider a4-10 to push the stop dog 4-2 to the upper part of the roller of the conveying line, the guide rail a4-11 is used for limiting the position of the stop dog 4-2 to prevent the stop dog from deviating, the printed circuit board 19 is stopped by the stop dog 4-2 forwards, then the direct current motor b4-4 drives the crank slider b4-10 to move, the push plate 4-3 extends out along the sliding groove 4-6, and when the printed circuit board 19 is touched, the printed circuit board 19 is pushed to move together to enable one side of the printed circuit board 19 to be attached to the alignment block 4-1, so that the alignment work is completed. The spring 4-7 has the effect of making the pusher 4-3 resilient and avoiding damage when pushing the printed circuit board 19.
After the alignment process is finished, the stepping motor b8-4 works, the lead screw guide rail b8-2 feeds towards the collecting device, the stripping plate 9 reaches the position right below the opening of the adhesive tape 20 of the printed circuit board 19, then the stepping motor a8-3 works to drive the lead screw guide rail a8-1 to move downwards, the stripping needle 9-1 reaches the position between the adhesive parts of the two adhesive tapes 20, after the position is determined, the stepping motor b8-4 works, the lead screw guide rail b8-2 continues to feed towards the collecting device, as shown in fig. 12, the stripping needle 9-1 is inserted between the two adhesive tapes 20, then the air cylinder 9-5 starts to work, the pressing plate 9-4 is pushed, the pressing plate 9-4 and the stripping needle 9-1 clamp the adhesive tape 20, then the stepping motor a8-3 works to drive the lead screw guide rail a8-1 to move upwards, and then the pressing plate 9-4 and the stripping needle 9-1 clamp the adhesive tape 20 upwards, meanwhile, the direct current motor a4-9 works to drive the crank slider a4-10 to retract the stop 4-2, and the printed circuit board 19 continues to advance. The force of the advancing force of the printed circuit board 19, the upward force of the adhesive tape 20 and the pressure of the roller b7-2 on the printed circuit board 19 in three directions cause the adhesive tape 20 to be peeled off, and when the printed circuit board 19 continues to advance out of the range of the roller a12 in the board conveyor belt 6, the pressure of the roller b7-2 on the printed circuit board 19 is changed into the pressure of the roller a12 on the printed circuit board 19 until the adhesive tape 20 is completely peeled off.
After the adhesive tape is completely peeled, the peeling needle 9-1 brings the adhesive tape 20 to the upper part of the actuating mechanism 4, at the moment, the stepping motor c10-4 feeds the adhesive tape, the lead screw guide rail c10-3 moves towards the upper part of the actuating mechanism 4 until the adhesive tape 20 completely enters between two parallel strip bodies of the collecting strip 10-2, then the direct current motor d10-5 works, the collecting strip 10-2 rotates to roll up the adhesive tape 20, and the collecting strip 10-2 is retracted after the collecting action is completed.
In the process of withdrawing the collecting strip 10-2, the direct current motor c works to drive the crank slide block c, so that the cutting knife moves upwards to stay between two parallel strip-shaped bodies of the collecting strip 10-2, the adhesive tape 20 is cut off along with the action of withdrawing the collecting strip 10-2, the adhesive tape is prevented from winding to block the adhesive tape collecting action of the next printed circuit board 19, and the adhesive tape stripping process is completed.
The invention can not corrode the circuit board in the process of tearing off the adhesive tape, can not damage the surface of the printed circuit board, saves manpower and material resources and realizes automation in the processing process of the printed circuit board.
