Abstract
The utility model provides a three-point positioning mechanism with a long-rod cylinder for a surface mounting tool, relating to automatic production equipment for electronic components, particularly a surface mounting tool (SMT). The long-rod cylinder (15) is fixed to a T-shaped seat, parallel and aligned to a cylinder center line as well as the center lines of two guide rods (6) and two spring rods (10) by a cylinder lock nut A (22) and a cylinder lock nut B (18) through a front fixing seat (8) of the cylinder and the bear fixing seat (20) of the cylinder, and air inlets A, B are arranged outward.
Description
The utility model relates to electronic devices and components automated production equipment, particularly surface stick-mounting machine (SMT).
Like product on the market has only two point location mechanism structure at present, and incompatibility SMT machine is in suction, correction, accurate, the flexible characteristic of paster requirement contraposition.
Of the present utility modelly provide a kind of surface stick-mounting machine stock three-point positioning mechanism, guarantee that the SMT machine wants accurate, motion flexibly in the contraposition of suction, correction, position, paster three place, and convenient as much as possible the adjusting, to adapt to the pcb board operation of different model.
Scheme of the present utility model is: surface stick-mounting machine long-rod cylinder three-point positioning mechanism, long-rod cylinder (15) by holder (20) behind holder (8) before the cylinder and the cylinder with cylinder locking nut A (22) and cylinder locking nut B (18) be fixed on T type seat (23) upper cylinder center line parallel with the center line of two guide rods (6) and two spring levers (10), align, and A, B connect gas port outwardly.Spring lever (10) front end is equipped with its medium position of buffer head (7) and an axle is housed is provided with one section screw thread (M6) with its afterbody of jump ring (11), is used for installing stroke adjustment nut (16) and locking nut one (17); Also corresponding two copper sheathings (13) that stud with also have a through hole, so that long-rod cylinder passes smoothly on spring lever sliding seat (14) on spring lever sliding seat (14); Holder (20) one plays the effect of fixed length bar cylinder (15) behind the cylinder, and the position that faces spring lever (10) on it also has 2 screwed holes, and stroke adjustment bolt (19) is installed in it; Pin is chewed seat (5) and is adopted high accuracy linear bearing (4) and guide rod (6), and guide pin is chewed seat (5) front a buffering bolt (2) is housed.Locate three kinds of state working conditions: initial state:
The air inlet of A mouth, B mouth are given vent to anger (speed all can be regulated by air valve), and the stroke adjustment bolt is used for metering needle and chews the position of returning, and the position mixes up the back and locks with locking nut.
Spring lever is smooth and easy slip in copper sheathing, its head match steel is used for wear-resisting and buffering, this moment, spring was in pressured state, its length difference (length of the length-compressive state of nature) and material, spring silk straight line and the number of turns etc. have strict demand, so that obtain a best elastic potential energy value, for future use.Intermediateness:
A mouth, the not air inlets of B mouth, spring reset (elastic potential energy release) pin is chewed by spring and is pushed out to accurate position (the stroke adjustment nut can accurately be controlled pin and chew the distance that is pushed out), mixes up back locking nut locking.At this moment, the residual gas in the long-rod cylinder A end just plays the effect of an air damping, and making that pin is chewed can springing.
Final states:
The air inlet of B mouth, A mouth are given vent to anger (speed all can be regulated by air valve), and there is buffering bolt (pin is chewed the position by bottom construction bolt adjustment) end.
Summary: common cylinder can only be realized two point locations (starting point, terminal point), and this mechanism has realized three-point fix (starting point, middle arbitrfary point, terminal point) by spring reset, certainly, the cylinder that the energy three-point fix is also arranged on the market, but that price is all expensive, this mechanism is then simple, cost is low, and repeatable accuracy can reach ± 0.01MM.Further specify below in conjunction with accompanying drawing:
Fig. 1 is that the utility model structure chart (initial state) Fig. 2 is that the utility model structure chart (intermediateness) Fig. 3 is the utility model structure chart (final states)
Among the figure, 1 connecting plate, 2 guide rods, 3 buffering bolts, 4, pin chew seat, 5, linear bearing, hit holder behind holder, 9 before cylinder, 6, buffer head, 8, the cylinder, copper sheathing, 10 spring levers, 11 jump rings, 12 springs, 13, copper sheathing, 14 spring lever sliding seats, 15 long-rod cylinders, 16 stroke adjustment nuts, 17 locking nuts (), 18, cylinder locking nut (B), 19, stroke adjustment bolt, 20, the cylinder down, 21 locking nuts (two), 22 cylinder locking nut A, 23, T type seat, 24 pins are chewed, 25 cylinder rod locking nuts, 26 pins are chewed the gear seat.Long-rod cylinder (15) DSNU-16-200PPV-A is fixed on the T type seat (23) with cylinder locking nut A (22) and cylinder locking nut B (18) by holder (20) behind holder (8) before the cylinder and the cylinder, during installation, guarantee that cylinder centerline is parallel with the center line of two guide rods (6) and two spring levers (10), align, and guarantee that A, B connect gas port outwardly.
2-spring lever (10) front end is equipped with buffer head (7), to improve resistance to wear and suitably to cushion; An axle is equipped with jump ring (11) in its appropriate location, middle part, forms a suitable elastic potential energy in order to spring (12); Its afterbody has one section screw thread (M6), is used for installing stroke adjustment nut (16) and locking nut one (17), and this nut is the stroke that is used for regulating release, in order to gripper correction place contraposition.
Holder (8) one plays the fixedly effect of long-rod cylinder (15) before the cylinder, in addition, also studs with two copper sheathings (9) (stopping with stopping screw) on it, and the coefficient of friction when moving to reduce spring lever (10) improves resistance to wear; Also corresponding two copper sheathings (13) that stud with on spring lever sliding seat (14) are in order that improve the guidance quality and the durability of spring lever (10) as far as possible under the future that reduces cost; In addition, on spring lever sliding seat (14), also have a through hole, so that long-rod cylinder passes smoothly.
Holder (20) one plays the fixedly effect of long-rod cylinder (15) behind the cylinder, in addition, the position that faces spring lever (10) on it also has 2 screwed holes, stroke adjustment bolt (19) is installed in it, it is to be used for the stroke that regulating spring bar (10) returns, in order to suction place contraposition, same, it also has locking nut two (21).
Pin is chewed seat (5) and is adopted high accuracy linear bearing (4) and guide rod (6) guiding, as previously mentioned, must strict guarantee two guide rods (6) and the depth of parallelism of cylinder (15) center line and aligning up and down of end face direction, could guarantee pin chew (25) smooth and easy and do not walk when mobile.
Pin is chewed seat (5) front a buffering bolt (2) is housed, and its material is a nylon, in order to buffering, wear-resisting and location usefulness.
In order to guarantee good repeatable accuracy, the threaded connection place of chewing seat (5) at cylinder rod (15) and pin is added with a cylinder rod locking nut (25), in order that locking (when SMT pasted material, its contraposition all around was to realize by the construction bolt of regulating T type seat (23) bottom).
Each position, hole requires to have well to neutrality during above-mentioned spare and accessory parts fabrication and installation, and these parts all are mounted on the T type seat (23), so, the installed surface that T type seat (23) is gone up each spare and accessory parts will guarantee to be in same plane, for this reason, the installed surface of T type seat (23) adopted grinding process (during grinding with its bottom installed surface be benchmark).
In a word, this design philosophy is exactly in order to guarantee that pin chews (25) and want accurate, motion flexibly in the contraposition of suction, correction, position, paster three place, and convenient as much as possible the adjusting, to adapt to the pcb board operation of different model.
