The specific embodiment
With a kind of conventional structure, principle substantially of the present utility model is described below, the normally vertical direction that picks up to sheet-like workpiece picks up, namely suction nozzle 2 is generally to pick up by vertical motion, is then moved on other stations or conveying mechanism.
Cut structure open with reference to the overlooking of suction nozzle 2 shown in explanation accompanying drawing 3, pore 18 in outstanding suction nozzle 2, omit sucker 1, matrix is a cuboid piece, upper and lower duct, right side represents pore 18, one end connects vacuum generating device, or self forms vacuum generator, other end connecting sucker 1 or other vacuum absorption devices.
Be, in the orthogonal direction of pore 18, to have a pair of horizontal guide hole 17, on suction nozzle, be provided with the guide pillar 14 for spacing conversion with respect to a side of pore 18.
See again Figure of description 1, have one group of suction nozzle 2, proper alignment, and being led by guide rail 12, thus in the guide direction of guide rail 12, can being adjusted of suction nozzle 2, thus the spacing between suction nozzle 2 just can be adjusted.
Structure below, for making the sway of suction nozzle 2 on track 12 in controlled state, is namely carried out spacing adjustment by the setting device that has concurrently being assemblied on main body frame 3.
In Fig. 1, suction nozzle structure is in a row, and in this row's a side, namely the normal direction of drawing inner side is spacing regulator, and this spacing regulator comprises adjusting head and driving adjusts head along the drive element moving perpendicular to described assigned direction.
As shown in Figure 2, adjusting module 16 is wherein adjustment head, it is having one group of conversion groove 13 with respect to a side of suction nozzle 2, as shown in Figure 2, in figure, the gradient of conversion groove is not identical, is final adjustment needs, only needs to have considered dot spacing (being origin or beginning spacing) and terminal spacing (being end spacing).
Connection source is to the conversion groove groove of terminal as path, and obviously straight path is more easily by those skilled in the art is understood.Therefore, it will be understood by those of skill in the art that changing groove by structure can form in the terminal spacing that plays dot spacing and distribution distributing, therefore, it designs and produces very simple.
Be to be understood that simultaneously, conversion groove 13 has been subject to the constraint of dot spacing and terminal spacing, because the corresponding spacing variation of conversion itself is not very large, therefore, the inclined degree of corresponding conversion groove 13 also can not be too large, therefore, produces the excessive possibility of friction angle smaller, thereby the inefficacy that wearing and tearing cause is relatively little.
And then as shown in Figure 2, by conversion groove 13, guide pillar 14 is directed to, be subject to changing the effect of groove horizontal direction component and produce horizontal motion, thus the relative position variation that produces a certain suction nozzle and other suction nozzles.
Fig. 2 has further demonstrated the structure that adjusting module 16 drives for pull bar 8, wherein also contain spring 10, what in fact form is spring assembly, obviously need to be configured to Compress Spring herein, Compress Spring, for fear of unstability, is furnished with spring perch conventionally, spring perch can form the guide frame of adjusting module 16, namely the spring perch lower end of cylindricality coordinates with adjusting module 16 hole axles, forms guide frame, and upper end is fixed on guide frame 15 as shown in Figure 2.
In certain embodiments, adjusting module can directly be directed at the frame of main body frame, forms the guide rail structure at the frame position as cliding window, and in order to reduce friction coefficient, frame guide rail place can also be used roller, forms friction of rolling.
Shown in Fig. 2 is single drive form, and obviously, double-acting drive form is also operable, as double acting air cylinder, can realize the control at two stops (dead point in other words), just the two ends of corresponding conversion groove.
And then about drive element, what Fig. 2 represented is a kind of drive element that very simply can manually control, as previously mentioned, can adopt cylinder to control, and in the time that employing is controlled as cylinder, more easily realizes automatically and controlling.And then, can also use other mechanical mechanisms to control, as lead screw pair, rack-and-gear etc. can be realized straight-line mechanical mechanism.
According to Fig. 1 and Fig. 2, principle of work is once described below:
Initial position in other words initial station by sucker 1(as conventional rubber suction nozzle) align with the chip that will draw, open vacuum by external vacuum controller chip be adsorbed on sucker 1.
By move to chip vacuum device used wanted carries chips as carrier band top.Then handle 7 is mentioned, drive spacing adjusting module 16 to rise by pull bar 8, now because of the effect of friction force, sucker 1 will be changed the track sway of groove 13 by the guide pillar 14 for spacing conversion according to spacing, and guide pillar 14 is connected with suction nozzle 2, sucker 1 is connected with suction nozzle 2, so the movement of guide pillar 14 will drive the movement of sucker, thereby inter-chip pitch is converted to the spacing matching with carrier band spacing, chip is corresponding with load bearing core film trap, close vacuum by external vacuum controller, chip will be put in chip groove.
Unclamp handle 7, spacing adjusting module 16 is put because the tension force of spring 10 sets back.Repeat above step, will complete the next action of putting of inhaling.
Do some explanations about some basic terms wherein below:
As illustrated in fig. 1 and 2, guide rail 12 is a pair of pilot bar, and simple in structure, cost of manufacture is lower, and in certain embodiments, can adopt other guide frame, simple with regard to the concept of guide rail, can adopt the guide rail of other types, as oat tail groove structure, on suction nozzle 2, form dovetail, and at the downside of main body frame, dovetail furrow is set, the position that does not affect adjusting module 16 arranges.
About single drive element, as previously mentioned, adopt pull bar 8 structures, can directly manually control, also can, based on straight-line motion, carry out the control of driver train to pull bar.In the time getting involved driver train, can also carry out the control of both direction, just form double acting mode.
When single-acting, can, based on as the automatically reseting of gravity, preferably adopt auxiliary reset structure, guarantee the efficiency resetting.Spring 10 as shown in Figure 2, spring is preferably provided with at least two, guarantees the equilibrium of reset force, avoids targeting part to produce increment load, the smoothness that impact resets.
