Description

A kind of PCB special backing plates automatic encapsulation device

Technical field

The utility model is related to encapsulation process fields, and in particular to a kind of PCB special backing plates automatic encapsulation device.

Background technology

For the prior art in big-and-middle based plate carries out plastic foil encapsulation process, majority is the collaborative work by multiple devices Sealed in unit is completed, the during which operations such as transfer, loading and unloading of flap material are required for consumption artificial and the time so that packaging efficiency is difficult To improve；Performance accuracy simultaneously because of personnel in encapsulation process is different, a degree of waste can be caused to material, virtually Increase cost, while expense needed for multiple devices and floor space also increase cost.

Invention content

To achieve the above object, the utility model adopts the following technical scheme：A kind of PCB special backing plates automatic packaging dress It puts, including rack, the operation console being horizontally set in rack, the transport mechanism being horizontally set on operation console is fixed on operation The driving mechanism of platform side, the packaging mechanism being arranged on above operation console, the packaging mechanism pass through company with the driving mechanism Extension bar is connected；The packaging mechanism includes the magazine being connect with the connecting rod, the bellows being arranged at the top of magazine, and the bellows lead to It crosses subtube to connect with main pipeline, is arranged on the set that suppresses of magazine bottom, the set that suppresses is transparent tubular structure； It is described suppress the internal magazine bottom of set and be additionally provided with roller, phoenix cylinder and cut-off knife, the roller be arranged on magazine bottom, center Axis is fixedly connected with the magazine, and the air duct is arranged on roller side, and the upper end is through magazine and is arranged on wind at the top of magazine Case connects；The cut-off knife is arranged between roller and air duct, is fixed on the magazine bottom.

The operation principle of the utility model is：Plank is placed in the transport mechanism surface being arranged on operation console during encapsulation, Driving device drives packaging mechanism to press to plate surface by connecting rod, suppresses the roller that set compression sets its hollow space With web contact.Adhere to the plastic film drawn out of magazine on roller, roll-in is put down in plate surface, plank with transport mechanism Row movement drives roller rotation to pull out plastic film roll-in out of magazine in plate surface, and the high wind blown out through air duct makes modeling Material film is bonded with plank, and air duct is connected across magazine with the bellows above magazine, and bellows are final by subtube and main pipeline The external air pump of connection, wind-force is provided by air pump.After roller is moved along plate surface until moving out plate surface range, sealing machine Structure continues to move downward, and roller is made to be moved downward along sheet edge, and the cut-off knife positioned at roller side is taken advantage of a situation will be between plank and roller Plastic film severing, roller contacts post package mechanism with roller band and moves up.

Further, the magazine and roller junction are provided with tapping channel, at the tapping channel outlet at bottom with Roller central shaft is fixedly connected, and driving roller is equipped in the tapping channel, it is logical with discharging that the driving roller is arranged on magazine The corner formed inside road.

Magazine extends one section of tapping channel, to draw the plastic film in magazine, at the outlet at bottom of tapping channel Connection is by roller, and the central shaft of roller is fixedly connected with discharge port bottom so that roller can be freely rotated in discharge outlet, will expect Plastic film in box is drawn, through roller roll-in to plate surface；For plastic film is made to be turned in magazine with what tapping channel was formed It is not scratched at angle, card resistance, driving roller is set in the corner plastic film to be made smoothly to pass through.

Further, the magazine is internally provided with unreeling shaft, and the unreeling shaft is fixedly connected with the magazine inner wall.

Unwinding equipment is provided in magazine, coiled plastic film is integrally put into wherein, by the central shaft for unreeling pedestal Plastic film is fixed so that plastic film rolls can be freely rotated and unreel with detaching for plastic film.

Further, the roller surface is provided with glue-line.

In the relatively low glue-line of roller surface setting viscosity, increase the frictional force between roller and plastic film, roller is avoided to beat It is sliding and so that plastic film took out to go out happens, and in addition completes primary encapsulation, after cut-off knife cut-out plastic film, glue-line Plastic film can be made to be adhered on roller convenient for encapsulation operation next time.

Further, the cut-off knife is fitted closely with the tapping channel, and the point of a knife of the cut-off knife is higher than the roller most Low spot, and less than tapping channel bottom end.

Cut-off knife is fitted closely with tapping channel, and the point of a knife of cut-off knife avoids encapsulating higher than roller minimum point, that is, plate surface Plastic film is scratched in movement, the point of a knife of cut-off knife is less than tapping channel bottom end for the knife of the cut-off knife after roller rolls down plate surface Point can protrude and cut off plastic film.

Further, the air duct bottom end is higher than the discharge port least significant end.

The bottom end of air duct be higher than discharge port bottom end because air duct apart from roller farther out, after roller rolls down plank, to avoid Air duct collides with plate surface.

Further, the transport mechanism is the horizontally arranged roller bearing transmission formed on the operation console surface of multiple roller bearings Band.

For the conveying speed for providing stronger holding power with stablizing, transport mechanism is using the horizontally arranged formation of multiple axis of rolling Transport plane.Compared to conveyer belt, roller bearing transport plane is not easy that plank is made to float up and down, and is conducive to roller in plate surface roll-in Plastic film.

The beneficial effects of the utility model are：The utility model combines process needed for encapsulation by simple mechanical structure It completes, improves work efficiency on same table apparatus, simultaneously because the device can be automatically performed the processes such as cutting, avoid Maintenance cost and space is also greatly saved in waste of material caused by during aritificial cut-off, only an equipment.
