[detailed description of the invention]
Contrast accompanying drawing below in conjunction with detailed description of the invention the utility model is described in further details.
As shown in Figure 4, be the structural representation of the absorption platform of this detailed description of the invention.Absorption platform comprises flat board 100, gripper shoe 102.Dull and stereotyped 100 is the antistatic plate it offering multiple circular hole, the antistatic sheet material of the polymer class such as such as PVC, PET, nylon, and antistatic plate is by wire 106 ground connection.In this detailed description of the invention, be grounded by the metal shell 21 connecting the motion platform below absorption platform.In other modes, the metal material part also by connecting other assembly is grounded, and the ground connection situation shown in Fig. 1 is not unique situation.Flat board 100 is positioned at the top of gripper shoe 102, and the sidewall of gripper shoe 102 and/or bottom offer the vent constructions 7 for connecting pump-line.Wherein, vent constructions 7 can be set in side or the bottom surface of absorption platform, and quantity can be one and arrive multiple.
Preferably, as shown in Figure 5, the diameter of the circular hole on dull and stereotyped 100 is at 0.5 ~ 1 millimeter, multiple circular hole array arrangement on antistatic, the column pitch of array arrangement, also namely the distance of center circle of transversely adjacent two circular holes is from D1, and the line space of array arrangement, also namely longitudinally the distance of center circle of upper adjacent two circular holes is 3 ~ 5 millimeters from D2.When arranging according to this size, absorption platform can produce the absorption affinity of general 20 ~ 30N, even if thus when adsorbing the components and parts of some surface warpage to some extent, also can firmly adsorb.It should be noted that, except the form of arranging according to square formation shown in figure, the form of any other dot matrix arrangement all can be used for herein, as long as line space and column pitch meet above-mentioned area requirement, such as, after circular hole arrangement peripherally form diamond shape, the staggered in the lateral or vertical direction latticed form of inner circular aperture also can be used for herein.In addition, the surface roughness of antistatic plate is less than 100 microns, thus antistatic plate is comparatively smooth, comparatively smooth when cutting material is placed on it.
The absorption platform of this detailed description of the invention, upper flat plate adopts antistatic material, relative to the flat board of prior art, adopt PC (Merlon) or PP (polypropylene) plastics more, antistatic plate in this detailed description of the invention can avoid accumulation of static electricity, even if produce a small amount of electrostatic, also ground is discharged into by external wire, Electro-static Driven Comb can not be carried out to the material to be cut that absorption platform is placed, even if cut the electronic devices and components such as FPC like this, also damage can not be caused to it.During operation, before cut FPC is placed on and is transported to laser cutting device in antistatic box, being taken out from antistatic box by FPC is positioned on antistatic platform, takes off and put back in antistatic box after laser cutting, can whole process prevent electrostatic from causing damage to FPC like this.Further, some FPC electronic devices and components produces warpage in process, therefore needs larger absorption affinity absorption firmly.When the aperture of the circular hole on antistatic plate and pitch of holes are in the size range of afore mentioned rules, absorption platform can produce the absorption affinity of general 20 ~ 30N, thus has the components and parts of warpage also can firmly adsorb to some surface.
As shown in Figure 4, preferably, adsorb flat board and also comprise cell structure 104.Cell structure 104 is positioned at the cavity of gripper shoe 102 inside.
As shown in Figure 6, be the schematic perspective view of cell structure.As shown in Figure 7, be the partial schematic diagram of sheet metal structure.Cell structure comprises staggered multiple sheet metal structure anyhow.Sheet metal structure is the sheet metal being provided with multiple hole 201 and groove 202, and groove 202 is arranged between two holes, for being fitted together to each other for two sheet metal structures.Shown in Fig. 6, a strip metal chip architecture offers in 17 holes 201, Fig. 7 and intercept local signal.Hole 201 is circular, and diameter can in 10 ~ 30mm.As shown in Figure 8, be the view that sheet metal structure is fitted together to each other, a sheet metal structure is longitudinally arranged, and another sheet metal structure is transversely arranged, and both are embedded by groove structure back-off, in right-angled intersection state.Cell structure is formed after multiple sheet metal structure of longitudinally setting and the sheet metal structure of multiple horizontally set intersect.Preferably, each grid of formation is cube structure, and its length of side is 15 ~ 40mm.If the grid length of side intersected to form is greater than 40mm, then effect is improved uniformly by not obvious to absorption affinity, be less than 15mm, then the too close absorption affinity of grid can be caused to diminish.
In above-mentioned lattice structure, the quantity in the hole that sheet metal is offered, the diameter in hole, the segmentation number of cavities that remote-effects are formed and volume thereof, in conjunction with the power of getter device, the parameters such as the size of blow vent, can arrange in pairs or groups each other by regulating these parameters, the size of the absorption affinity in cavity can be controlled.
In above-mentioned preferred version, lattice structure is set up in gripper shoe internal cavities, negative pressure cavity is divided into some little cavitys, be connected by the hole in lattice structure between cavity, flow velocity even in each little cavity can be made like this, make absorption affinity in whole cavity even, solve the problem of diverse location absorption affinity great disparity.The absorption platform of traditional structure, in internal cavities, the areas adjacent gas flow rate near apart from blow vent is high, therefore the cavity area suction near blow vent is large, cavity area suction away from blow vent is little, cause dull and stereotyped some region upper to adsorb material to be cut, some region then can not effectively be adsorbed.And in this detailed description of the invention, by the setting of lattice structure, making absorption affinity in cavity even, on flat board, various loci absorption affinity is even, even if adsorb some materials that are bending or warpage, also can adsorb smooth.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, make some substituting or obvious modification without departing from the concept of the premise utility, and performance or purposes identical, all should be considered as belonging to protection domain of the present utility model.
