Further, the fixed clamping plate of described mobile terminal parts below and be provided with translation clamping cylinder in the inner side of mobile side plate.
Described mobile terminal parts are driven by Width adjusting mechanism, and described Width adjusting mechanism is made up of bearing, screw mandrel, track, the wide stepping motor of tune, driving pulley, active band and driven pulley; Described bearing is laid on track for supporting fixed side or mobile side plate; On described bearing, nut is installed, between every a pair of bearing, passes through nut connection wire rod; Described screw mandrel one end is coaxially installed with driven pulley; Driven pulley is with and is connected driving pulley by active, and driving pulley is arranged on stepping motor output shaft.
Described mobile terminal parts are driven by two cover Width adjusting mechanisms, and this two covers Width adjusting mechanism is realized synchronously by synchronous pulley component; Described Timing Belt assembly is made up of Timing Belt and synchronous pulley, and synchronous pulley connects by Timing Belt; Described synchronous pulley is coaxially arranged on screw mandrel.
Described conveyer belt moves clamp system and clamps from above, move on described clamp system by interior plate, active clamped plate, on move leg, on move top board and on move cylinder and form; Described interior plate moves leg and supports from above, active clamped plate is installed on interior plate; On described, move leg and move top plate supporting from above; On described, move top board by air cylinder driven.
The import department of described first paragraph conveying mechanism is provided with into plate inductor, and the exit of second segment conveying mechanism is provided with ejecting plate inductor.
The end of described first paragraph conveying mechanism and second segment conveying mechanism is all provided with block, and by air cylinder driven.
Compared with prior art, the present invention has increased a set of conveyer belt mechanism, not only can carry two block lengths to be less than the pcb board of 750mm specification, and paster efficiency is enhanced about more than once, can also carry monolithic length to be greater than the pcb board of 750~1500mm specification, be applicable to large-scale pcb board and mount production line.

Embodiment
As shown in Figure 1, plate feeding device comprises that two sections of conveyer belt mechanisms (first paragraph conveyer belt mechanism 1 and second segment conveyer belt mechanism 2), a set of Width adjusting mechanism composition and two put and move clamp system, conveyer belt mechanism is for delivery of pcb board, and Width adjusting mechanism is used for adjusting conveyer belt mechanism width.
As shown in Figure 1 to Figure 3, conveyer belt mechanism respectively by stepping motor 3, conveyer belt 4, fixed side 5, mobile side plate 6, fixed clamping plate 7, on move guide rail 8, positioning datum plate 9 and translation clamping cylinder 10 and form.Conveyer belt 4 is driven by stepping motor 3.Fixed side 5 wherein, fixed clamping plate 7, on move guide rail 8 and positioning datum plate 9 is assembled into stiff end parts.And mobile side plate 5, fixed clamping plate 7 and on move guide rail 8 be assembled into can horizontal anomalous movement mobile terminal parts.Fixed clamping plate 7 be positioned at fixed side 5 or mobile side plate 6 above.Between the fixed side 5 of stiff end assembly and fixed clamping plate 7, be provided with positioning datum plate 9.Translation clamping cylinder 10 is positioned at mobile terminal parts,, is up to the standard and clamps the object of pcb board to conveyer belt mechanism medial movement for Level Promoting pcb board 11.
As shown in Figure 1, Width adjusting mechanism by bearing 12, screw mandrel 13, track 14, adjust wide stepping motor 15, driving pulley 16, be initiatively with 17, driven pulley 18, synchronous pulley 19, counter wheel 20 and Timing Belt 21 form.Bearing 12 carries conveyer belt mechanism entirety.Adjust wide stepping motor 15 to drive driving pulley 16, one end of screw mandrel 13 is coaxially installed with driven pulley 18 and synchronous pulley 19.The nut thread assembling arranging on screw mandrel 13 and bearing 12.Adjust when wide, adjust wide stepping motor 15 to start, drive driving pulley 16, by being initiatively with 17 driving driven pulleys 18, driven pulley 18 drives screw mandrel 13-1 to rotate, and meanwhile, driven pulley 18 drives coaxial synchronous pulley 19-1 to rotate, synchronous pulley 19-1 drives synchronous pulley 19-2 by Timing Belt 21, and synchronous pulley 19-2 drives screw mandrel 13-2 to rotate.The rotation of screw mandrel 13, has driven bearing 12 to slide along track 14, adjusts wide action thereby realize.Between two synchronous pulleys 19, be provided with counter wheel 20, be conducive to regulate the elasticity of Timing Belt.
