The prepreg (commonly called as PP (Polypropylene)) is a basic insulating material for manufacturing the PCB, and the PP is a sheet material of the prepreg. The thinnest thickness of the PP material is 20 microns according to thickness distinction, and materials with the thickness of 20-80 microns are generally selected for PCB process production. Because the original material of PP is coil stock, dust is easy to generate in the PP sheet separating and cutting process, and the conductivity of the PP plastic plate is poor, the generated static electricity can not flow, and the static electricity accumulation is large.
At present, the loading state of the clients is a stacked prepreg, and each prepreg can be processed in the next step only after being taken independently. However, due to long-term lamination, static electricity accumulation can be generated between adjacent prepregs, dust is easily adsorbed, and even static negative pressure is generated, so that the prepregs are difficult to take out.
The prior art discloses an utility model patent with the application number of 201821948403.9 and the patent name of a prepreg feeding device, which clamps and transfers prepregs from a stacking rack to a conveying belt through a material taking clamp, and in the clamping process, because static electricity between adjacent prepregs easily causes vacuum negative pressure between the adjacent prepregs, the uppermost prepreg is easy to bring out the adjacent prepregs below when being taken out, and the uppermost prepreg also seriously causes static scratch or wrinkles, and if the scratch or the wrinkles occur, dust can fall off and the PP insulation effect is destroyed, so that the production quality of a PCB is affected.
In order to solve the above-mentioned problems, the present embodiment discloses an air-float ion layering method for prepregs, which can be applied to a prepreg separating apparatus shown in fig. 2, and the apparatus mainly comprises a feeding end 100, a discharging end 200, a bottom plate 302, a driving mechanism 301, an ion wind generating device 400 and a discharging mechanism 500. Since the height of stacked prepregs is gradually reduced after the prepregs are discharged, the driving mechanism 301 needs to be arranged to adjust the position of the bottom plate 302 at any time, namely, the bottom plate 302 is lifted under the action of the driving mechanism 301, and meanwhile, the laser range finder is matched to accurately detect the height change of the prepregs, so that the uppermost prepreg is ensured to always maintain a certain height, and the stability of discharging is improved.
It should be noted that, the structures and principles of the driving mechanism 301 and the ion wind generating device 400 in this embodiment are all the prior art, and are not described herein.
Specifically, this prepreg separation equipment is when using:
s100, placing stacked prepregs at a feeding end 100;
s200, introducing ion wind between the uppermost prepreg of the stacked prepregs and the adjacent prepregs, removing static electricity between the uppermost prepreg and the adjacent prepregs and enabling the uppermost prepreg to be in a floating state;
s300, taking out the prepregs in the floating state in the step S200 to a discharge end 200;
s400, judging whether the stacked prepregs are completely fed, if the prepregs are not fed, sequentially repeating the steps S200-S300, otherwise, re-executing the steps S100-S400.
In this embodiment, in order to enable the ionized wind generated by the ionized wind generating apparatus 400 to be accurately guided between the prepreg at the uppermost layer and the adjacent prepreg below, step S101 is added between step S100 and step S200, and the step S101 is as follows: the prepreg at the uppermost end is adjacent to the side to be introduced with the ion wind, and the side is grasped and lifted by using a pickup device. Although a certain adsorption effect is generated between the adjacent prepregs due to static electricity, the uppermost prepreg and the lower prepreg can be separated by a certain distance to a certain extent by applying an upward force to the side of the uppermost prepreg, which is close to the air outlet of the ion wind generating device 400, through the pickup device, so that the ion wind can be accurately guided between the uppermost prepreg and the adjacent lower prepreg.
Specifically, the pickup device in this embodiment is a suction cup or a finger clamping cylinder, preferably a suction cup, so that the integrity of the surface of the prepreg can be ensured to the greatest extent.
Further, in order to make the separation between the prepregs more stable, in this embodiment, a baffle is disposed at one side of the pickup device, and the baffle is used for pressing the prepreg to be close to one side where the ion wind is to be introduced, when the pickup device needs to pick up the uppermost prepreg and drive the prepreg to rise, the prepreg will contact with the baffle first, and then the prepreg passes over the baffle under the drive of the pickup device, if at this time, the prepreg and the adjacent prepreg below the prepreg are adhered, the prepreg below cannot rise under the blocking of the baffle, and the effect of separating two prepregs is achieved. In this embodiment, the baffle is preferably made of a material with a certain elasticity and a lower hardness, and is subjected to a certain smoothing treatment, so that scratches of the prepreg when the prepreg passes over the baffle can be avoided to the greatest extent.
Specifically, in step S200, the ionic wind generating device 400 is used to guide the ionic wind in the fan-shaped range facing the air outlet of the ionic wind generating device 400 between the uppermost prepreg and the adjacent prepregs, where the fan-shaped range may be a continuous area or a separated area, and a single or multiple fan-shaped ranges may be adjusted according to the width of the prepregs; in addition, at least one ion wind generating device 400 can be set according to the width of the prepreg, so as to ensure the stability of the uppermost prepreg when floating.
Further, after the prepreg floats and static electricity is removed, the floating prepreg is taken away and discharged by a discharging mechanism 500 arranged at a discharging end 200, the discharging mechanism 500 is preferably a roller or a multi-axis manipulator, the roller is used for discharging the prepreg through friction, and meanwhile, a vacuum suction hole can be arranged at the roller to suck the prepreg, so that the discharging success rate of the prepreg is improved; the blanking is transmitted by a conveyor belt.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the scope of the present utility model, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
