Description

Technical Field

[0001] The invention relates to the technical field of packaging technology, and in particular to a roll-to-roll room-temperature packaging process for full-color micro-layers with adhesive backing. Background Art

[0002] The existing packaging technology uses high-molecular materials such as PVB and EVA for high-temperature lamination. The lamination principle is to apply a certain pressure on the surface of each layer of the component material, and press these materials tightly together under heating. This process usually consists of four major systems: heating system, vacuum system, pneumatic system, and control system. Specifically, the working process of the laminator is as follows: the component to be laminated enters the laminator and is heated, the EVA melts, and the gas volatilized from the chamber and the component is vacuumed out, and then pressurized to cross-link and solidify PVB and EVA. This process has high energy consumption and requires high temperatures, and is not suitable for flexible thin-film solar cells that require low-temperature packaging.

[0003] Traditional packaging processes have problems such as high energy consumption, high temperature, and overall rigidity after cross-linking and curing. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of the present invention to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] The purpose of the present invention is to address the technical problems existing in the background technology. The present invention proposes a room temperature packaging process for roll-to-roll full-color micro-layer with adhesive backing. The present invention can effectively improve the packaging processing stability of flexible batteries through this process. The device adopts a room temperature bonding packaging process for processing, thereby avoiding the heating link of the battery raw materials and reducing the risks of flexibility reduction or battery short circuit caused by overheating of the battery raw materials. At the same time, the room temperature bonding processing can effectively reduce the energy consumed in the battery packaging process, thereby reducing the energy consumption of the packaging process.

[0006] The present invention proposes a room temperature packaging process of a full-color micro-layer with adhesive backing, which comprises the following steps:

[0007] S1 flexible battery loading step, in which the flexible battery raw material is unfolded from the raw material roller, so as to facilitate the subsequent processing of the flexible battery surface;

[0008] S2 is a step of tensioning the flexible battery, in which the flexible battery is tensioned by multiple sets of elastically sliding tensioning wheels, and the flexible battery passes through the outer arc surfaces of several tensioning wheels in a serpentine shape, and the elastic sliding of the tensioning wheels makes the flexible battery in a tensioned state after passing through the tensioning wheels;

[0009] S3 is a step of loading the adhesive-backed full-color micro-layer packaging material, in which the adhesive-backed packaging material is unrolled from the raw material roll to facilitate subsequent processing operations;

[0010] S4 is a step of separating the surface isolation film, in which the isolation film on the surface of the packaging material can be separated by an isolation film winding roller, and the isolation film is attached to the adhesive surface of the packaging material to prevent the packaging materials from sticking to each other when they are in an unloaded and wound state, and the adhesive surface of the packaging material is exposed after the isolation film is separated;

[0011] S5: tensioning the packaging material. In this step, the packaging material is tensioned by using multiple sets of elastically sliding tensioning wheels. The packaging material passes through the outer arc surfaces of several tensioning wheels in a serpentine shape. The elastic sliding of the tensioning wheels makes the packaging material in a tensioned state after passing through the tensioning wheels.

[0012] S6: laminating the flexible battery with the packaging material. In this step, the unfolded flexible battery and the packaging material can be laminated on the surface by a laminating mechanism. When the flexible battery and the packaging material pass through the laminating mechanism, the adhesive back surface of the packaging material contacts and adheres to the surface of the flexible battery by extrusion of the laminating mechanism.

[0013] S7: curing the packaging material. In this step, the packaging material attached to the surface of the flexible battery can be UV-cured by a UV tunnel lamp. The cured packaging material is tightly attached to the surface of the flexible battery.

[0014] S8 is a step of winding up the finished product. In this step, the combination of the flexible battery and the packaging material can be rotated and rolled up through the winding roller structure, thereby completing the processing of the flexible battery. At the same time, the winding step can provide power for the feeding process of the flexible battery and the packaging material in the above steps.

[0015] By adopting the above technical solution, the present solution synchronously drives and pulls the flexible battery and the packaging material through the winding roller, thereby ensuring that the feeding speed of the flexible battery and the packaging material is the same, thereby achieving stable bonding processing.

[0016] Preferably, in the step S1, the raw material roller for feeding the flexible battery is provided with a rotation damping structure with adjustable rotation resistance, and the rotation damping structure has the function of adjusting the rotation resistance of the flexible battery raw material roller.

[0017] By adopting the above technical solution, this solution can adjust the rotational resistance of the raw material roller through the rotational damping structure during the process of the winding roller pulling the flexible battery, thereby ensuring that the flexible battery will not hesitate to cause relaxation due to the rotational inertia of the raw material roller.

[0018] Preferably, in the step S2, the elastic sliding directions of several tensioning wheels used to tension the flexible battery material are opposite, the flexible battery passes from one side of the outer arc surfaces of the several tensioning wheels away from each other and drives the tensioning wheels to rotate, and the tensioning wheels achieve elastic sliding through elastic structures such as springs.

[0019] By adopting the above technical scheme, the present scheme can tension the transmission process of the flexible battery through the structure of several tensioning wheels. When the flexible battery becomes loose, the several tensioning wheels slide away from each other through elastic structures such as springs, thereby tensioning the strip-shaped flexible battery, thereby ensuring the transmission stability of the flexible battery.

[0020] Preferably, in step S4, the isolation film winding roller has a power device, the outer arc surface of the isolation film has a clamping structure for clamping one end of the isolation film, and the isolation film is wound around the outer arc surface of the isolation film winding roller during the rotation of the isolation film winding roller.

[0021] By adopting the above technical solution, the present solution can conveniently control the rotation speed of the isolation film winding roller through the power equipment, thereby ensuring that the winding speed of the isolation film is the same as the feeding speed of the packaging material, thereby avoiding the accumulation of raw materials.

[0022] Preferably, in step S6, the laminating mechanism includes two transmission rollers, the flexible battery and the packaging material pass through the two transmission rollers, the two transmission rollers rotate freely and squeeze each other, and the flexible battery and the packaging material drive the transmission rollers to rotate.

[0023] By adopting the above technical solution, the present solution can provide a uniform extrusion effect on the packaging material and the flexible battery through the extrusion method of two driving rollers, thereby ensuring the stability of the bonding processing of the present device.

[0024] Preferably, in step S7, the UV tunnel lamp comprises an inverted U-shaped lamp rack, on which UV lamps are evenly spaced, and the UV lamps face the direction of the flexible battery and the packaging material.

[0025] By adopting the above technical solution, the present solution can perform a curing process on the bonded packaging material through the structure of the UV lamp, thereby reducing the risk of the packaging material accidentally falling off from the surface of the flexible battery.

[0026] Preferably, in the step S8, the winding roller has a power device, and the outer arc surface of the winding roller has a clamping structure, and the clamping mechanism clamps and connects one end of the flexible battery and the packaging material composition, so that the flexible battery and the packaging material composition are wound on the outer arc surface of the winding roller.

[0027] By adopting the above technical solution, the present solution can provide uniform pulling force to the flexible battery and the packaging material through the structure of the winding roller, thereby reducing the risk of accidental breakage of the flexible battery and the packaging material during the winding transmission process.

[0028] In summary, the present invention includes at least one of the following beneficial effects:

[0029] This process can achieve room temperature processing effects on flexible batteries and packaging materials. Compared with traditional battery packaging processing technology, this device avoids high temperature environment and pre-tensions the flexible battery and packaging material, so that both materials are in a tensioned state when they are bonded, thereby avoiding wrinkles in the processed combined material and ensuring the stable use of the flexible battery. At the same time, this device separates the isolation film on the surface of the packaging material before the bonding process, thereby ensuring that the adhesive on the packaging material is in the maximum viscosity state for bonding with the flexible battery, reducing the risk of impurities entering between the packaging material and the flexible battery.

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0032] The following is combined with Figure 1 The present invention is described in further detail.

[0033] Embodiment 1

[0034] like Figure 1 As shown, in order to solve the existing problems, in this embodiment, the present invention discloses a roll-to-roll room temperature packaging process of a full-color micro-layer with adhesive backing, including the following steps:

[0035] S1 flexible battery loading step, in which the flexible battery raw material is unfolded from the raw material roller, so as to facilitate the subsequent processing of the flexible battery surface;

[0036] S2 is a step of tensioning the flexible battery, in which the flexible battery is tensioned by multiple sets of elastically sliding tensioning wheels, and the flexible battery passes through the outer arc surfaces of several tensioning wheels in a serpentine shape, and the elastic sliding of the tensioning wheels makes the flexible battery in a tensioned state after passing through the tensioning wheels;

[0037] S3 is a step of loading the adhesive-backed full-color micro-layer packaging material, in which the adhesive-backed packaging material is unrolled from the raw material roll to facilitate subsequent processing operations;

[0038] S4 is a step of separating the surface isolation film, in which the isolation film on the surface of the packaging material can be separated by an isolation film winding roller, and the isolation film is attached to the adhesive surface of the packaging material to prevent the packaging materials from sticking to each other when they are in an unloaded and wound state, and the adhesive surface of the packaging material is exposed after the isolation film is separated;

[0039] S5: tensioning the packaging material. In this step, the packaging material is tensioned by using multiple sets of elastically sliding tensioning wheels. The packaging material passes through the outer arc surfaces of several tensioning wheels in a serpentine shape. The elastic sliding of the tensioning wheels makes the packaging material in a tensioned state after passing through the tensioning wheels.

[0040] S6: laminating the flexible battery with the packaging material. In this step, the unfolded flexible battery and the packaging material can be laminated on the surface by a laminating mechanism. When the flexible battery and the packaging material pass through the laminating mechanism, the adhesive back surface of the packaging material contacts and adheres to the surface of the flexible battery by extrusion of the laminating mechanism.

[0041] S7: curing the packaging material. In this step, the packaging material attached to the surface of the flexible battery can be UV-cured by a UV tunnel lamp. The cured packaging material is tightly attached to the surface of the flexible battery.

[0042] S8 is a step of winding up the finished product. In this step, the combination of the flexible battery and the packaging material can be rotated and rolled up through the winding roller structure, thereby completing the processing of the flexible battery. At the same time, the winding step can provide power for the feeding process of the flexible battery and the packaging material in the above steps.

[0043] This process can ensure the stability of the loading process of flexible batteries and packaging materials during the processing through independent loading structures, and can ensure that each raw material is in a tensioned state before the bonding process by using independent tensioning structures, thereby avoiding problems such as wrinkles and relaxation during the bonding process.

[0044] After the flexible battery is unrolled from the raw material roll, it is tensioned and accurately bonded to the packaging material. At this time, the isolation film on the surface of the packaging material can be removed by the rotation of the isolation film winding roller, thereby exposing the back adhesive surface for subsequent bonding processing. By removing the isolation film before bonding, the risk of the back adhesive surface being contaminated by impurities in the air can be reduced, thereby avoiding problems such as the introduction of impurities during the bonding process.

[0045] After removing the isolation film from the packaging material, the packaging effect is achieved by pressing the adhesive back surface of the packaging material and the flexible battery against each other.

[0048] In the step S2, the elastic sliding directions of several tensioning wheels used to tension the flexible battery material are opposite, the flexible battery passes from the side of the outer arc surfaces of the several tensioning wheels that are away from each other and drives the tensioning wheels to rotate, and the tensioning wheels achieve elastic sliding through elastic structures such as springs.

[0049] In the step S4, the isolation film winding roller has a power device, the outer arc surface of the isolation film has a clamping structure for clamping one end of the isolation film, and the isolation film is wound around the outer arc surface of the isolation film winding roller during the rotation of the isolation film winding roller.

[0050] In the step S6, the laminating mechanism includes two transmission rollers, the flexible battery and the packaging material pass through the two transmission rollers, the two transmission rollers rotate freely and squeeze each other, and the flexible battery and the packaging material drive the transmission rollers to rotate.

[0053] The specific working principle is:

[0054] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
