Description

Paint spraying platform

Technical field

The utility model provides a kind of Paint spraying platform, be meant especially a kind of in order to clamping and make workpiece location, with the convenient anchor clamps of workpiece being carried out spray painting operation.

Background technology

The plastics part of general ejection formation, often need for some, often need comprehensive or local spraying paint done on its surface, in the past owing to lack a kind of simply and effectively anchor clamps, can be on this plastic product, carrying out spray painting operation, so mostly rely on manually-operated, this kind production method not only lacks efficient, and can't obtain evenly to reach accurate quality.

And promptly address the above problem in No. 84211029 Taiwan patent disclosed " workpiece that sprays paint anchor clamps pallet ", this Paint spraying platform is in order to clamping and makes the workpiece location, be convenient to surface of the work is carried out the anchor clamps of spray painting operation, it mainly is made up of pedestal, carriage, two pneumatic cylinders, some suckers and air pressure assembly, wherein carriage can load and unload and be incorporated into freely on the pedestal, in order to supporting workpiece; Two pneumatic cylinders are installed on the pedestal both sides respectively, after its piston pole passes pedestal roof and carriage, connect to T shape with a tappet; Sucker is individually fixed in pedestal roof four corners, and is connected with a vacuum generator; Fall mould pipeline output and when flowing into vacuum when gas is following, because venturi-effect causes negative pressure appearance, make sucker produce suction and workpiece is adsorbed on the carriage, so that surface of the work is sprayed paint; Rise mould pipeline when output when gas is following, the gas passage that is connected to vacuum is cut off, so sucker loses suction and release work, simultaneously gas enter pneumatic cylinder following, piston rod released tappet risen, so as to lifting high workpiece, be convenient to take off workpiece.

The Paint spraying platform that known technology provides be because of can and making workpiece location for clamping, convenient surface of the work carried out spray painting operation, for the raising efficient of spraying paint, reduces production costs, and is very favourable.Yet, for the plastic casing of notebook computer, mobile phone etc., be not completely only to a certain surface lacquer, the loam cake of notebook computer for example, except that upper surface will spray paint, after basal surface was installed the position of LCDs at deduction, remaining privileged site also will spray paint in the lump, so that go up exterior surface color and luster unanimity.

Because lying against, workpiece makes the carriage move both vertically, thus quite convenient during execution upper surface spray painting operation, but will carry out the basal surface spray painting operation time, just difficult relatively many.Therefore, be to utilize two tool Paint spraying platforms on the practice, respectively workpiece surface and basal surface are carried out spray painting operation, though this measure is feasible, can increase the technology that workpiece is converted to another Paint spraying platform, and because of the multiplication of work-handling number of times, the efficient of spraying paint is significantly reduced, and production cost greatly improves.

The utility model content

Main purpose of the present utility model is to provide a kind of Paint spraying platform, this Paint spraying platform removes to have clamping and makes the workpiece location, outside conveniently workpiece surface being sprayed paint, and increases the die holder turn over function, the workpiece basal surface can be convenient to the privileged site of basal surface is carried out spray painting operation up.

For achieving the above object, the Paint spraying platform that the utility model provides includes a pedestal, establish a rotatable carriage in the pedestal top, and on carriage, be connected with a die holder, the workpiece that the clamping location desires to spray paint on die holder, between this die holder and the carriage and be provided with drive mechanism, and the drives structure that drives the drive mechanism rotation, make die holder can do the upsets of at least 180 degree now with respect to carriage via the drive of this drive mechanism; Can and make the workpiece location via the clamping of this die holder whereby, be convenient to workpiece surface is sprayed paint, the die holder of supporting workpiece can turn over turnback simultaneously, makes the workpiece basal surface up, in the lump its basal surface privileged site is carried out spray painting operation.

In addition, another feature of the present utility model is, this drive mechanism is installed a sprocket wheel respectively at a side upper and lower of carriage, in between two sprocket wheels, supply a chain above hanging over, each is connected with a lower piston rod with the upper piston rod of a pair of bar pneumatic cylinder and this drives structure is included in chain two ends, by the stretching motion push-pull chain of this upper and lower piston rod, rotatablely move to this two sprocket wheels conduction from chain again, the die holder that is linked to sprocket wheel is rotated synchronously.

In addition, another being characterized as of the present utility model, this drive mechanism is provided with gear train in a side of carriage, it is by tooth bar, first driven pulley, second driven pulley and the 3rd driven pulley be meshing with each other constitute, tooth bar is connected with the single pole pneumatic cylinder of drives structure, make tooth bar do upper and lower displacement along with the flexible of single pole pneumatic cylinder, and first driven pulley, one side is meshed with tooth bar, opposite side then is meshed with second driven pulley, the second driven pulley opposite side is meshed with the 3rd driven pulley again, the 3rd driven pulley then is connected with die holder, does the upset of at least 180 degree with respect to carriage via the drive of gear train to make die holder.
