Abstract
The utility model discloses a bonding sheet pressing pallet, which comprises a bonding sheet insulating board; and the bonding sheet pressing pallet is characterized in that: the pallet also includes a metal frame and another bonding sheet insulating board; two bonding sheet insulating boards are respectively covered on the upper and the lower surfaces of the metal frame; the outer peripheries of the three are matched with each other, and the bonding sheet insulating boards and the metal frame are fixedly connected with each other by bolts running through a plurality of screw holes which are positioned at each corresponding position. Through the connection of the bonding sheet insulating boards and the metal frame, the bonding sheet pressing pallet effectively improve the carrying capacity and service life, and avoid the iron pollution; thereby being particularly applied to the long term use in the industries such as the CCL (copper-clad plate) industry and the PCB (printed circuit board) industry.
Description
Technical field
The utility model relates to a kind of turnover, shipping, storage pallet, is specifically related to a kind of bonding sheet pressing pallet, is usually used in the copper-clad plate industry.
Background technology
Pallet (pallet) is the modern industry production, turnover, transportation, the important carrier of storage.Along with the raising of conveyorization degree, use amount is increasing.At present common pallet can be divided into insulation pallet and nonisulated pallet by purposes, applicable situation difference, and corresponding with it is the difference of material, the pallet made of paper of insulation class (as, the corrugation pallet), the metal stack plate of nonisulated class (iron pallet) etc.
Bonding sheet is the adhesives that arrives commonly used in the SMT technology, and Copper Foil is through bonding sheet and the substrate pressurized that is heated in laminating machine, the adhesion agent melting above the bonding sheet and bonding sheet is become an integral body with Copper Foil, substrate bonding, the formation copper-clad plate.As seen, the yields of the product confrontation copper-clad plate of bonding sheet plays a decisive role, thereby depositing and having enough to meet the need of bonding sheet all had higher requirement.At present the copper-clad plate industry is used in bonding sheet transportation, storage mostly is bonding sheet pressing metal stack plate, the corrosion-resistant steel pallet that pallet or electroplating processes cross that insulate.
Find in use that so all there is the defective that can't overcome separately in this two classes pallet.The former: described bonding sheet is to be matrix by glass cloth, through guiding roller, is soaked in the glue groove (resin adhesive liquid), by the plastic squeeze roller, enters baking oven then behind the impregnation, and glue is solidified, and is the bonding sheet insulcrete with multi-layered bonded sheet pressing and forming, makes pallet thus.Pallet under this composition structure, though be the only carrier of carrying bonding sheet, the undercapacity of itself, determined that this class pallet load-carrying capacity is relatively poor, bonding sheet stacks limited amount, and certainly will need increases pallet quantity and storage area, and influences the life-span of repeated use; The latter: though metal stack plate has good loading strength, yet in transportation, be difficult to the meeting avoided and conveying cylinder or other metallic equipment direct friction and produce chips such as iron powder, the bonding sheet that bears is polluted, finally influence the normal making and the quality of copper-clad plate.
Summary of the invention
The utility model purpose provides a kind ofly has good bearing capacity, and is beneficial to the bonding sheet pressing pallet that bonding sheet is deposited.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bonding sheet pressing pallet, comprise the bonding sheet insulcrete, described bonding sheet insulcrete is made of last bonding sheet insulcrete and following bonding sheet insulcrete, also include a metal framework, described upper and lower bonding sheet insulcrete is covered in the upper and lower surface of described metal framework respectively, and three's outer peripheral edges face matches, and, be mutually permanently connected through screw by the screw on a plurality of opposite positions in twos.
In the technique scheme, the bonding sheet insulcrete that covers is gone up on described metal framework and upper and lower two surfaces, its three's outer peripheral edges face matches, it is consistent that this cooperation is three's size, perhaps bonding sheet is slightly larger than the outer rim of metal framework, thereby forms the covering of bonding sheet insulcrete to the metal framework surface.
In the technique scheme, described metal framework is made of shaped steel, and described shaped steel surface electrical is coated with rust proof layer.Described rust proof layer can adopt the existing plating process technology, and electro-galvanized layer or nickel phosphorus etc. prevent that the shaped steel that constitutes framed structure from producing iron rust in the long-term use process, effectively avoid the pollution to bonding sheet.
In the technique scheme, described metal framework is intersected with a plurality of longitudinal rods by a plurality of transverse bars and constitutes, along being furnished with a plurality of screws on each transverse bar and the longitudinal rod respectively at interval, be respectively equipped with the countersunk head screw that matches on the described upper and lower bonding sheet insulcrete at corresponding each screw place, upper and lower bonding sheet insulcrete warp is threaded with metal framework with the flathead screw that described countersunk head screw is complementary.
In the technique scheme, on described upper and lower bonding sheet insulcrete, corresponding each described screw place is coated with fixedly glue-line, fixedly glue-line can by screw thread glue or all purpose adhesive constitutes for this, when making, take a morsel at every turn and be applied to the screw thread place, fix again, to prevent the screw loosening that long-term use causes or to come off.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, owing to the utility model is fixedly formed by upper and lower bonding sheet insulcrete and the stack of metal framework between the two, so overcome is merely that bonding sheet pressing insulation pallet load-carrying capacity is poor, the shortcoming of insufficient strength, can avoid simultaneously metal stack plate in transportation, to produce the problem of pollution bonding sheets such as iron filings, help good preservation to bonding sheet, and improve the load-carrying capacity of pallet, prolong pallet service life;
2, use flathead screw fixedly bonding sheet insulcrete and metal framework, the fixedly setting of glue-line of cooperation can improve triangular fix tightly soundness, avoids screw loosening or comes off;
3. when using the shaped steel construction framework, shaped steel electroplating surface rust proof layer prevents that shaped steel from producing iron rust in the long-term use process, effectively avoid the pollution to bonding sheet.
