All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides an FPC transfer book for safely transferring and transporting FPC between production processes, and with reference to fig. 1 and 2, the FPC transfer book includes a top sheet, a plurality of partition sheets, a bottom sheet, and a bottom outer shell sheet, which are sequentially stacked and bound in a book from top to bottom.

Specifically, bind into the volume with top sheet, interlayer board, bottom plate and bottom shell board, compare in prior art and directly take the barrier paper to keep apart, have the advantage that makes FPC be difficult for polluting, stable, the transportation of depositing safely. When binding, on one hand, the firm stability of the binding is considered, on the other hand, the clamping tightness and the safety of the FPC product are also considered due to the fact that the FPC product is clamped, the quantity and the capacity of the FPC are also considered, the preferred mode of binding is butterfly binding, butterfly binding approximately appears in the later stage of Tang dynasty, is mainly carried out in the Song dynasty, pages of a book are folded inwards according to a center seam, the pages of the book are aligned according to the center seam, pasted on another packaging paper by paste, and finally cut into a binding mode of a book. The butterfly suit has the advantages of being hard and firm after being bound, free of influence of more pages, and suitable for clamping the firmness and the containing quantity required by the FPC.

The interlayer plate is used for placing the FPC between the two interlayer plates, and a plurality of protrusions which are equidistant from the edges and are arranged at intervals are arranged near two adjacent edges of the front surface of the interlayer plate respectively.

Specifically, after the FPC is clamped between the interlayer plates, the FPC is easy to move and slide in the transportation process, so that the protrusions are arranged on the edges of the page of the interlayer plates, and the FPC can be fixed to prevent the FPC from sliding. The arrangement of the protrusions can be arranged on one edge of the paper, and also can be arranged on two, three or four edges, the protrusions are not arranged, so that better compatibility is achieved for different sizes of FPCs, the FPC can be better prevented from sliding due to arrangement on four sides, the protrusions are preferably arranged near two adjacent edges in consideration of the compatibility and the fixity of sizes of single plates or jointed plates of the FPC. In addition, the number of the protrusions can be set according to needs, and preferably, the number of the protrusions of each edge is not less than 2.

Referring to fig. 3, the protrusions are bottomless hollow cavities, forming a bell-shaped depression in the back of the interlayer sheet that nests with a protrusion in the same location as the next interlayer sheet.

Specifically, after the FPC is clamped, if the protrusions are too high, the FPC is placed between the interlayer plates relatively loose and easy to slide. The arrangement of the bottomless hollow protrusions can be formed by directly extruding the protrusions on the release paper, or can be formed by firstly punching holes on the release paper and then plugging the holes with the protrusions in the bell-shaped structure. Preferably, the hollow bottomless protrusion with a bell-shaped structure is directly extruded on the isolation paper, so that the materials are kept consistent, and the production is simple and convenient.

Further, the protruding outer surface and the recessed inner surface thereof are coated with a magnetic layer.

Specifically, in the scene of using mechanical equipment to get and put transportation FPC automatically, can be at protruding external surface and sunken inside surface coating magnetic layer, thereby machine equipment can adsorb the magnetic layer automatically and guide the interlayer board to turn over the page or leaf to the position that needs automatically like this, conveniently gets and puts FPC, gets the concrete working process of putting FPC and can be for: when placing the FPC, firstly turning over the bottom plate of the FPC circulation body, stacking the last interlayer plate of a page turning over by mechanical equipment in an adsorbing mode on the bottom plate, placing one FPC on a proper position (which can be stably supported by a protrusion) on the last interlayer plate, stacking the penultimate interlayer plate of the page turning over in an adsorbing mode on the interlayer plate on which the FPC is just placed, nesting the depression on the back of the penultimate interlayer plate and the protrusion on the front of the last interlayer plate at the moment to better fix the FPC of the first plate, then attracting the penultimate interlayer plate of the page turning over by the mechanical equipment, and so on … …; when taking out FPC, at first open the top sheet that FPC circulates originally, mechanical equipment adsorbs automatically to open the first page of interlayer board, takes out the FPC of placing between first, two pages of interlayer boards, and mechanical equipment adsorbs again to open the second page of interlayer board, takes out the FPC of placing between second, three pages of interlayer battings, analogizes in this way … … to accomplish the automatic page turning that adsorbs of machine equipment, improve operating efficiency.

Further, the number of the interlayer plates is 100.

Specifically, the number of the interlayer plates can be set to be selected from 50, 100, 200 and the like according to needs. If the number of settings is too small, the efficiency is low, and if the number of settings is too large, the stability is affected. Preferably, in the invention, the number of the interlayer plates is set to be 100, which is moderate and facilitates counting statistics.

Referring to fig. 4, a handle extends from a side of the interlayer plate, and the front and back surfaces of the handle are coated with magnetic layers.

Specifically, in some production scenes, the FPC is taken and placed manually, and at the moment, a handle extends out of the interlayer plate, so that an operator can turn pages through the handle to quickly take and place the FPC. In some production scenes, mechanical equipment is partially adopted for automatic operation, so that magnetic layers are coated on the front and back surfaces of the handle, and the mechanical equipment can automatically adsorb and turn pages. It should be noted that if the magnetic layer is coated on the division plate with the handle, the mechanical equipment can conveniently and automatically adsorb and turn pages, the protection performance of the FPC product is better than that of the FPC product which is coated on the inner and outer surfaces of the protrusion for adsorbing and turning pages, and the scratch possibly generated on the FPC product by the uneven coating of the magnetic layer on the protrusion is reduced.

Referring to fig. 5, the outer edges of the top surface of the top plate and the bottom surface of the bottom casing plate are provided with magnetic fasteners that can be attracted to each other.

Specifically, when FPC product clamp is put into FPC circulation originally back, the time that needs the save sometimes is longer or the distance of circulation is longer, and this probably has dust or wind to blow apart barrier paper etc. and thus pollute FPC of FPC circulation this during this, in the invention, through set up the magnetism hasp of mutual absorption between this table plywood of FPC circulation and bottom plate skin, enable this closed better of FPC circulation, thereby the bad environmental pollution who receives is deposited or circulates for a long time to fine avoidance.

Further, the interlayer plate is made of sulfur-free paper with the size of A4 paper.

Specifically, the size of the interlayer can be set according to the actual production requirement, the A4 paper can be selected to adapt to most FPC single boards or jointed boards, and the compatibility is good. The sulfur-free paper is selected as the interlayer plate, and has the following three characteristics that the sulfur-free paper does not contain sulfur and cannot react with a silver layer deposited on the surface of the FPC, and the sulfur-free paper is used for isolating the FPC plate, so that the contact between silver and sulfur can be effectively reduced; secondly, the sulfur-free paper can also play a role in isolation, so that the copper layer below the silver deposition layer is prevented from reacting with oxygen in the air; and thirdly, the sulfur-free paper has the property of high temperature resistance, can resist the high temperature of about 180 ℃, has better anti-skid performance and is used as a good material of FPC interlayer paper.

Further, the top and bottom skin panels are made of kraft paper. The top and bottom skin plates are the same size and have a length and width slightly greater than the length and width of the interlayer plate.

Specifically, the kraft paper is selected as the surface layer plate and the bottom layer outer shell plate, the tear strength is resisted, the tensile force is high, the kraft paper has the main quality characteristics of flexibility and firmness, the kraft paper can bear large tensile force and pressure, the kraft paper is not broken, and the support performance is good; in addition, the performance of the kraft paper is determined that the kraft paper can be recycled and reused for many times, the regeneration is environment-friendly, the price is not high, and the cost is saved. The size of the surface layer plate and the bottom layer shell plate is slightly larger than that of the interlayer plate, so that the interlayer plate can be better accommodated, and the accommodation and protection can be better realized when a plurality of FPCs are clamped.

Further, the bottom plate is made of FR 4.

In particular, FR4 has fire resistance, does not absorb water, maintains higher mechanical load and good insulating capability in dry or humid environment, and is provided with FR4 material on a bottom layer plate, so that a plurality of FPC boards can be better borne and the FPC can be protected from adverse effects of external environment.
