With after the clamping fuse of fuse carrier, by the control of PLC control system, drive and carry out self-feeding, location, clamping, punching by each device, efficiently, accurately complete the punching processing of 6 fuses.
2. a kind of automation equipment for fuse punching according to claim 1, it is characterized in that: described fuse carrier is in the time of clamping fuse, by the alignment pin location on locating hole and carrier on fuse, clamp by pressing plate and magnet.
3. a kind of automation equipment for fuse punching according to claim 1, it is characterized in that: the material toggling pawl of described servo feeding device is made up of " L " type fixed head and elasticity catch pawl, " L " type fixed head is bolted on conveyer belt, and elasticity catch pawl is fixed on " L " type fixed head lower end; Elasticity catch pawl is positioned at the both sides of fuse carrier, under the drive of conveyer belt, along guide rail mobile insurance silk carrier, can realize the accurate control to carrier stand.
4. a kind of automation equipment for fuse punching according to claim 1, it is characterized in that: in described hole punched device, 3 groups of cam punching pin mechanisms that punching is driven by servomotor complete in succession, and every group of cam is responsible for the stamping-out in 6 holes on 2 fuses; Whenever servomotor central shaft turns over 120 °, 1 group of cam punching pin mechanism completes punching, therefore enclose when servomotor central shaft has turned one the punching processing that completes 6 fuses.
5. a kind of automation equipment for fuse punching according to claim 1, it is characterized in that: the each drift group in described hole punched device is made up of macropore drift and aperture drift, drift group has 3, belong to respectively 3 cam punching pin mechanisms, it is 6 drifts in 6 holes of 2 fuses that each drift group has 1 group of stamping-out, and drift is fixed on same fixed block and length differs; Wherein differ a fuse metal foil thickness of slab for two punch length of stamping-out macropore, and be all longer than 4 drifts of stamping-out aperture; 4 two, drift outsides for stamping-out aperture are equal in length, and two of inner sides length also equates, and the length of two drifts of inner side is compared the two short fuse metal foil thicknesss of slab in outside.
6. a hole-punching method for the automation equipment for fuse punching as claimed in claim 1, is characterized in that comprising the steps:
(1) first manually 6 fuses are arranged on fuse carrier pedestal by alignment pin, through gathering sill compression fuse, make it in fuse carrier motion process, be difficult for dropping with " L " type pressing plate; Then, the fuse carrier assembling is placed on the material toggling pawl of servo feeding device IV;
(2) start PLC control system, the servomotor of servo feeding device receive control system send the signal of telecommunication after start rotate, drive conveyer belt by the rotation of decelerator speed change rear drive belt pulley, belt pulley, thereby drive material toggling pawl and fuse carrier to travel forward along guide rail, until fuse carrier arrives after the machining position being preset under positioning clamping device, servomotor stops operating;
(3) arrive after machining position positioning clamping device setting in motion at fuse carrier; First the cylinder of vertical direction positioner starts to promote transmission mechanism and moves downward along guide pillar after the signal of telecommunication that receives PLC control system, move downward thereby promote alignment pin, by the locating hole on " L " type pressing plate of fuse carrier, fuse carrier is carried out to the restriction of horizontal direction position; Meanwhile, the cylinder of horizontal direction positioner promotes movable block and travels forward under the guidance of PLC control system, and then drives block B and T-shape location-plate to travel forward, and associating block A is by clamping fuse-positioning carrier to fuse two ends; Complete behind location, the cylinder of vertical direction positioner continues motion, promotes pressing plate fuse carrier is clamped, for follow-up punching processing is prepared;
(4) after the location of fuse carrier has been clamped, hole punched device is accepted the signal of telecommunication setting in motion of PLC control system, motor drives the power shaft of synchrome conveying belt by shaft coupling, thereby drive camshaft to rotate, make cam punching pin mechanism form vertical direction motion by the cam being fixed on camshaft; Because 3 groups of cam angles are 120 °, will justify trisection, therefore camshaft driving cam punching pin mechanism kinematic in succession in rotation completes the punching processing of one group of two fuse in every group of descending process of cam punching pin mechanism; And owing to being fixed on same fixed block for the drift group of one group of two fuse punching and each punch length differs, therefore in punch process, two drifts of large punching head contact with sheet metal in succession, two contact metal films in outside in 4 drifts of then little punching head, the two drift contact metal films in last inner side, so carry out successively to complete the stamping-out in 6 holes on 1 group of 2 fuse;
(5) complete after the punching of 6 fuses, the cylinder of Lifting Device, under PLC control system is ordered about, promotes top board and push rod and moves upward, thereby fuse carrier is ejected, and is convenient to follow-up fuse carrier and shifts out machining position.
