Description

Technical Field

[0001] The utility model belongs to the technical field of copper clad laminate processing, and more specifically relates to a packaging device for packaging packaging paper such as laminated paper onto a copper clad laminate. Background Art

[0002] Copper clad laminate is also called copper foil laminate. Copper clad laminate is a plate-like material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin to make an insulating board, then covering one or both sides of the insulating board with copper foil and hot pressing. Copper clad laminate is the basic material of the electronics industry and is widely used in electronic products. After the copper clad laminate is processed, it needs to meet the requirements of moisture-proof, anti-oxidation, and anti-scratch during storage and transportation. Therefore, the processed copper clad laminate needs to be packaged with packaging paper. Laminated paper has strong toughness, good waterproofness and wear resistance, and is widely used in the packaging industry of copper clad laminate finished products.

[0003] When packaging copper clad laminates, it is necessary to control the unwinding tension of the wrapping paper to ensure the flatness of the packaging material. At the same time, it is also necessary to avoid the phenomenon of bursting packages during stacking, storage and transportation due to the presence of air after packaging, which affects the overall integrity and storage of the packaging. In the existing copper clad laminate packaging process, if both sides of the copper clad laminate are to be packaged, the copper clad laminate needs to be turned over, which has many operation steps and low efficiency. In view of the above problems, it is necessary to develop a copper clad laminate packaging device with high efficiency and good lamination effect. Utility Model Content

[0018] The utility model is described in detail below in conjunction with the accompanying drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] like Figure 1 As shown, the copper clad laminate packaging device of this embodiment includes a first finished product board conveying mechanism 1, a first packaging paper feeding mechanism 2, a second packaging paper feeding mechanism 3, a transverse heat sealing cutter module 4, an exhaust roller 5, a longitudinal heat sealing module 6 and a second finished product board conveying mechanism 7.

[0021] The first finished board conveying mechanism 1 and the second finished board conveying mechanism 7 are arranged at intervals in front and behind. The first and second finished board conveying mechanisms are used to convey the boards to be packaged, such as copper-clad boards. The finished board conveying mechanism can adopt conventional conveying mechanisms such as belt conveyors and roller conveyors. The first finished board conveying mechanism 1 is used to convey the boards to be packaged from the preceding station to the heat-sealing station where the second finished board conveying mechanism 7 is located. The copper-clad boards wrapped with packaging paper such as laminated paper are heat-sealed at the heat-sealing station. After the heat-sealing is completed, the second finished board conveying mechanism 7 delivers the boards.

[0022] The first packaging paper unloading mechanism 2 and the second packaging paper unloading mechanism 3 are respectively located at the upper and lower sides of the first finished board conveying mechanism 1. The first packaging paper unloading mechanism 2 and the second packaging paper unloading mechanism 3 are both used for unloading packaging paper. The first packaging paper unloading mechanism 2 includes a first material reel 2-1 and a first unwinding tension roller 2-2. The packaging paper material roll is installed on the first material reel 2-1. The first material reel 2-1 of this embodiment adopts an air-expanding shaft. The air-expanding shaft passes through the wrapping paper roll core and is inflated, so that the axial displacement of the packaging paper along the roll core can be controlled during the unwinding process. After the packaging paper such as coated paper is unwound from the material roll, the coated surface faces the copper-clad board. The first unwinding tension roller 2-2 is used to pull the unwinding of the packaging paper. The first unwinding tension roller 2-2 can rotate around its own axis when driven by a motor (not shown), thereby controlling the conveying speed and tension of the packaging paper.

[0023] The structure of the second packaging paper unwinding mechanism 3 is the same as that of the first packaging paper unwinding mechanism 2, and also includes a second material reel 3-1 for mounting the packaging paper roll and a second unwinding tension roller 3-2 for pulling the unwinding of the packaging paper. After the two rolls of packaging paper are unwound from the first packaging paper unwinding mechanism 2 and the second packaging paper unwinding mechanism 3 respectively, the coated surfaces of the packaging paper are both facing the copper clad laminate.

[0024] Optionally, the copper clad laminate packaging device of this embodiment further includes a steering roller 9, the function of which is to adjust the conveying direction of the wrapping paper. The direction of the wrapping paper after unrolling in this embodiment is still roughly along the moving direction of the plate. The wrapping paper is turned 90 degrees by the steering roller 8. After passing the steering roller 8, the conveying direction of the wrapping paper is perpendicular to the moving direction of the plate 100. When the conveying direction of the wrapping paper after unrolling is perpendicular to the moving direction of the plate 100, the steering roller 9 may not be provided.

[0025] The transverse heat-sealing cutter module 4 is located between the first finished board conveying mechanism 1 and the second finished board conveying mechanism 7. After the packaging paper is unrolled, it is sent to the transverse heat-sealing cutter module 4. The heat-sealing cutter module 4 of this embodiment includes a first heat-sealing knife 4-1, a second heat-sealing knife 4-2 and a cutter 4-3. The first heat-sealing knife 4-1 and the second heat-sealing knife 4-2 are opposite to each other in upper and lower parts, and the first heat-sealing knife 4-1 and the second heat-sealing knife 4-2 have the same structure and are symmetrically arranged in upper and lower parts.

[0026] The first heat sealing knife 4-1 and the second heat sealing knife 4-2 can move relative to each other, so as to approach or move away from each other. The first heat sealing knife 4-1 and the second heat sealing knife 4-2 both extend in the transverse direction. The transverse direction of the utility model refers to the direction perpendicular to the conveying direction of the plate, and the longitudinal direction refers to the direction parallel to the conveying direction of the plate. Figure 1 The direction is indicated by the middle arrow A. The first heat sealing knife 4-1 and the second heat sealing knife 4-2 are used to heat seal the packaging paper transversely.

[0027] The following uses the first heat sealing knife 4-1 as an example to illustrate the structure of the first and second heat sealing knives. The vertical cross-section of the first heat sealing knife 4-1 is a concave shape, and a heating rod is arranged inside the heat sealing knife for bonding the coated paper. When the upper and lower heat sealing knives are pressed together, the heat sealing knife with a concave structure can form two horizontal adhesive strips arranged at intervals in front and behind. A cutter 4-3 is arranged in the notch of the concave structure, and the tip of the cutter 4-3 is flush with the hot pressing surface of the first heat sealing knife 4-1 (the surface of the heat sealing knife in contact with the packaging paper during heat sealing), so that when the first heat sealing knife 4-1 and the second heat sealing knife 4-2 are pressed together, the cutter 4-3 can cut the packaging paper. The cutter 4-3 of this embodiment adopts a sawtooth cutter with a vertical cross-section shape of a triangle. Since the position of the cutter 4-3 is located between the two adhesive strips, the packaging paper can be cut while heat sealing and bonding, which not only ensures the continuity of the operation and improves the efficiency, but also avoids the generation of excess scraps during packaging and reduces waste. In other embodiments, the first heat sealing knife may also be composed of two transverse heat sealing knives spaced apart in front and back, with the cutting knife located between the two transverse heat sealing knives. The second heat sealing knife has the same structure, but adopts the integrated concave-shaped mechanism of this embodiment, which is simpler and more compact.

[0028] Further optionally, the packaging paper unloading mechanism of the present embodiment also includes a buffer roller 8, and the buffer roller 8 and the unwinding tension roller are arranged adjacent to each other. Taking the first packaging paper unloading mechanism 2 as an example, a buffer roller 8 is arranged before the first unwinding tension roller 2-2. The packaging paper successively passes around the buffer roller 8 and the first unwinding tension roller 2-2 to form an S shape, thereby reducing the tension fluctuation impact caused by uneven force on the packaging paper during the movement.

[0029] The longitudinal heat sealing module 6 is arranged behind the transverse heat sealing cutter module 4. The longitudinal heat sealing module 6 includes two pairs of longitudinal heat sealing knives 6-1 arranged opposite to each other up and down, and the longitudinal heat sealing knives 6-1 extend in the longitudinal direction. The two pairs of longitudinal heat sealing knives 6-1 are respectively located on the left and right sides (lateral sides) of the plate conveyed by the second finished plate conveying mechanism 7, and are used to perform longitudinal heat sealing on the packaging paper, that is, one pair of longitudinal heat sealing knives 6-1 is located on the left side of the plate, and the other pair of longitudinal heat sealing knives 6-1 is located on the right side of the plate. When the two pairs of longitudinal heat sealing knives are pressed together, two longitudinal heat sealing adhesive strips are formed on the left and right sides of the plate. The longitudinal heat sealing knives 6-1 of this embodiment can move up and down under the action of the cylinder. The longitudinal heat sealing knives opposite to each other up and down can be the upper knife moving and the lower knife fixed, or the upper and lower knives can both move, or the upper knife is fixed and the lower knife moves. The distance between the two pairs of longitudinal heat sealing knives 6-1 can also be adjusted, such as using a screw rod to connect the two pairs of longitudinal heat sealing knives, and adjusting the distance between the two pairs of longitudinal heat sealing knives by the screw rod to meet the packaging requirements of finished plates of different sizes.

[0030] The exhaust roller 5 is arranged at the second finished board conveying mechanism 7, and the exhaust roller 5 can be located at the upper and lower sides of the second finished board conveying mechanism 7, or located above the second finished board conveying mechanism 7. The exhaust roller 5 of this embodiment is arranged at the feed end of the second finished board conveying mechanism 7, and is located above the second finished board conveying mechanism 7. The exhaust roller 5 can rotate around its own axis, and the axis of the exhaust roller 5 is perpendicular to the conveying direction of the plate, that is, the axis of the exhaust roller 5 is arranged in the horizontal direction. The exhaust roller 5 is an unpowered roller, and there is no driving mechanism to drive it to rotate. After the exhaust roller 5 is pressed on the packaging paper on the surface of the copper clad board, it can rotate with the advancement of the copper clad board to smooth the packaging paper, and squeeze the gas inside the packaging paper during the smoothing process to exhaust the gas, so that the packaging paper fits the surface of the copper clad board. Optionally, the exhaust roller 5 is provided with a compression spring, and the exhaust roller 5 can be pressed against the surface of the copper clad board by the compression spring, and the pressure of the exhaust roller 5 can be adjusted.

[0031] Combine the following Figure 1 , the laminated paper packaging process of the copper clad laminate packaging device of this embodiment is described.

[0032] The laminated paper rolls are respectively mounted on the material reels of the two packaging paper unloading mechanisms. The first packaging paper unloading mechanism 2 and the second packaging paper unloading mechanism 3 unload the laminated paper respectively, so that the laminated paper passes around the buffer wheel 8, the unloading tension roller, and the steering roller 9 respectively. The head of the packaging paper is initially bonded at the transverse heat sealing cutter module 4, so that the two rolls of laminated paper are connected together.

[0033] The first finished plate conveying mechanism 1 conveys the plate 100 along Figure 1 The sheet 100 is transported in the direction indicated by the arrow A. When the front end of the sheet 100 contacts the coated paper, the first unwinding tension roller 2-2 and the second unwinding tension roller 3-2 start to rotate under the drive of the motor, so that the unwinding and conveying of the coated paper can be synchronized according to the feeding speed of the first finished plate conveying mechanism 1.

[0034] When the front end of the sheet 100 moves against the laminated paper bonded to the head, the laminated paper covers the upper and lower surfaces of the sheet 100;

[0035] When the sheet 100 moves to the position of the exhaust roller 5, the exhaust roller 5 presses on the surface of the sheet 100 and presses the laminated paper covering the surface of the sheet 100 tightly against the sheet 100. As the sheet 100 moves forward under the conveyance of the second finished sheet conveying mechanism 7, the exhaust roller 5 is driven to rotate, thereby smoothing the wrinkles of the laminated paper and making the laminated paper completely adhere to the surface of the sheet 100, and exhausting the air between the laminated paper and the sheet during the rolling process.

[0036] When the front end of the plate 100 moves to the rear end of the second finished plate conveying mechanism 7, the second finished plate conveying mechanism 7 is paused, and the first heat sealing knife 4-1 and the second heat sealing knife 4-2 of the transverse heat sealing cutting knife module 4 and the longitudinal heat sealing knife 6-1 of the longitudinal heat sealing module 6 move toward each other and are pressed together, so as to perform heat-melt sealing on the three open edges of the coated paper, and at the same time, the cutter 4-3 in the transverse heat sealing cutting knife module 4 cuts off the coated paper and the material roll;

[0037] After the heat sealing knives reach the preset heat pressing time, the heat sealing knives separate and reset, and the second finished plate conveying mechanism 7 transports the packaged plates to the subsequent workstations.

[0038] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the utility model should be included in the scope of the utility model.
