DETAILED DESCRIPTION
[0032] The utility model will be described in detail below in combination with the drawings.
[0033] Referring to Figure 1The utility model discloses a full -automatic production line of printing formula electrochromic film, including frame 1, the unwinding mechanism 2, electrochromic ink printing device 3, thermal curing mechanism 4, gel electrolyte printing device 5, UV curing mechanism 6 and compound and winding mechanism 7 that frame 1 is sequentially provided with,
[0034] The unwinding mechanism 2 is used for conveying the lower substrate;
[0035] The electrochromic ink printing device 3 is used for printing the color-changing ink on the lower substrate to form an electrochromic layer;
[0036] The thermal curing mechanism 4 is used for curing the electrochromic layer;
[0037] The gel electrolyte printing device 5 is used for printing an electrolyte layer on the electrochromic layer;
[0038] The UV curing mechanism 6 is used for curing the electrolyte layer;
[0039] The compound and winding mechanism 7 is used for conveying the upper substrate and combining the upper substrate with the lower substrate to form an electrochromic film.
[0040] The electrochromic ink printing device 3 and the gel electrolyte printing device 5 have high-precision control ability, which can ensure the uniform printing of ink and electrolyte, thereby generating an electrochromic film with stable quality and excellent performance. The thermal curing mechanism 4 and the UV curing mechanism 6 further enhance the structural stability and durability of the film.
[0041] Compared with the traditional production method, the production line reduces material waste and improves material utilization by accurately controlling the supply of ink and electrolyte. This not only reduces production costs, but also helps environmental protection.
[0042] Through the cooperation of the unwinding mechanism 2, the electrochromic ink printing device 3, the thermal curing mechanism 4, the gel electrolyte printing device 5, the UV curing mechanism 6 and the compound and winding mechanism 7, the full-automatic process from unwinding, printing color-changing ink, thermal curing, printing electrolyte layer, UV curing to compounding and winding is realized. Each process is seamlessly connected, which significantly improves production efficiency, reduces manual intervention and reduces production cost. This innovative design not only greatly improves production efficiency and reduces production cost, but also significantly improves product quality and consistency.
[0043] Specifically, the full-automatic production line automatically transports the lower substrate through the unwinding mechanism 2, ensuring the continuity and stability of the production process. The electrochromic ink printing device 3 precisely controls the supply of ink, achieving uniform printing of the electrochromic ink on the lower substrate, forming a high-quality electrochromic layer. The thermal curing mechanism 4 then rapidly cures the electrochromic layer, enhancing its stability and durability. Subsequently, the gel electrolyte printing device 5 precisely prints the electrolyte layer on the electrochromic layer, providing the necessary conductive and ion transmission channels for the electrochromic film. The UV curing mechanism 6 then efficiently cures the electrolyte layer, ensuring the structural stability and performance reliability of the entire electrochromic film. Finally, the composite and winding mechanism 7 automatically transports the upper substrate and precisely composites it with the lower substrate, forming a complete electrochromic film and automatically winding it, providing convenience for subsequent processing and application.
[0044] The unwinding mechanism 2 of this embodiment includes an unwinding shaft 21 and a bearing roller 22, both of which are rotationally arranged on the mechanism. The unwinding shaft 21 is used to transport the lower substrate, and the bearing roller 22 is used to support and bear the lower substrate.
[0045] The unwinding mechanism 2 can stably and continuously transport the lower substrate through the coordinated action of the unwinding shaft 21 and the bearing roller 22, ensuring the smooth progress of subsequent printing, curing, and other processes. This helps to improve the overall stability and production efficiency of the production line.
[0046] The design of the bearing roller 22 can effectively support the lower substrate, preventing it from being damaged due to excessive tension or friction during transportation. This helps to maintain the flatness and integrity of the lower substrate, thereby improving the quality of the final product.
[0047] The electrochromic ink printing device 3 of this embodiment includes a first vacuum suction plate 31, an electrochromic ink inkwell 32, an ink printing roller 33, and an ink jet head 34.
[0048] The first vacuum suction plate 31 is fixed to the rack 1 and is used to fix the lower substrate. The electrochromic ink inkwell 32 is arranged above the first vacuum suction plate 31. The ink printing roller 33 is rotationally arranged on the electrochromic ink inkwell 32 and is used to print the electrochromic ink on the upper substrate to form an electrochromic layer. The ink jet head 34 is connected to the electrochromic ink inkwell 32 and is used to spray ink onto the ink printing roller 33.
[0049] The electrochromic ink printing device 3 can achieve precise printing of the electrochromic ink through the coordinated action of the ink printing roller 33 and the ink jet head 34. During rotation, the ink printing roller 33 uniformly receives ink from the ink jet head 34 and transfers it to the lower substrate to form an electrochromic layer. This design ensures the accuracy and consistency of printing, improving the quality of the product.
[0050] Since the ink printing roller 33 and the ink jet head 34 can work quickly and continuously, the electrochromic ink printing device 3 can greatly improve production efficiency. This is of great significance for large-scale industrial production, helping to shorten the production cycle and reduce production costs.
[0051] The ink jet head 34 can reduce ink waste by precisely controlling the amount of ink sprayed. At the same time, the uniform printing of the ink printing roller 33 also avoids material waste caused by uneven distribution of ink. This helps to reduce production costs and improve resource utilization.
[0052] The electrochromic ink fountain 32 of the embodiment is provided with an ink tank 35 and a first liquid level sensor 36, and the ink tank 35 supplies electrochromic ink to the electrochromic ink fountain 32;
[0053] The first liquid level sensor 36 is used to monitor the ink amount in the electrochromic ink fountain 32, wherein the first liquid level sensor 36 is an ultrasonic liquid level sensor.
[0054] The first vacuum suction plate 31 is connected with a vacuum pump.
[0055] The ink tank 35 provided in the electrochromic ink fountain 32 can stably supply electrochromic ink to the printing device, ensuring the continuity and stability of the printing process. This helps to improve the printing quality and production efficiency of the product.
[0056] The setting of the first liquid level sensor 36 enables the ink amount in the electrochromic ink fountain 32 to be monitored in real time. When the ink amount is lower than the preset threshold, the system can automatically issue a warning or trigger a refilling mechanism, thereby avoiding printing interruption caused by insufficient ink. This intelligent monitoring function improves the automation and stability of the production line.
[0057] The first vacuum suction plate 31 is connected with a vacuum pump, which can firmly fix the lower substrate and prevent it from moving or deforming during the printing process, thereby affecting the printing quality. This design ensures the accuracy and consistency of printing and improves the quality of the product.
[0058] Through intelligent monitoring of ink amount and stable ink supply, downtime and maintenance costs caused by insufficient ink or quality problems can be reduced. At the same time, stable fixation of the lower substrate also reduces equipment damage and maintenance requirements caused by material movement.
[0059] The electrochromic ink printing device 3 of the embodiment comprises a dust removal roller 37, which is arranged between the unwinding mechanism 2 and the electrochromic ink fountain 32.
[0060] The dust removal roller 37 can effectively remove dust, impurities and other contaminants on the surface of the substrate, ensuring that the ink can be evenly and unobstructed coated on the substrate during the printing process.
[0061] The clean substrate surface helps the adhesion and curing of the ink, thereby improving the flatness and consistency of the electrochromic film.
[0062] The dust removal roller 37 is usually made of soft and wear-resistant materials, such as sponge, flannel or special synthetic fibers (such as anti-static fibers) etc. During the printing process, the dust removal roller 37 contacts and rolls through the surface of the substrate with appropriate pressure and speed, thereby removing dust, impurities and other contaminants attached to the substrate.
[0063] The gel electrolyte printing device 5 of the present embodiment includes a second vacuum suction plate 51, an electrolyte ink fountain 52, an electrolyte printing roller 53, and an electrolyte ink supply single valve 54.

[0065] The gel electrolyte printing device 5 can accurately print the gel electrolyte layer on the electrochromic layer through the cooperation of the electrolyte printing roller 53 and the electrolyte ink supply single valve 54. During rotation, the electrolyte printing roller 53 uniformly receives the gel electrolyte from the electrolyte ink supply single valve 54 and transfers it to the electrochromic layer to form a uniform electrolyte layer. This ensures the accuracy and consistency of the electrolyte layer and improves the performance of the product.
[0066] The rapid and continuous operation of the electrolyte printing roller 53 and the electrolyte ink supply single valve 54 enables the gel electrolyte printing device 5 to greatly improve production efficiency. This helps to shorten the production cycle and meet the needs of large-scale industrial production.
[0067] The electrolyte ink supply single valve 54 can reduce material waste by accurately controlling the amount of gel electrolyte sprayed. At the same time, the uniform printing of the electrolyte printing roller 53 also avoids performance degradation or material waste due to uneven distribution of electrolyte.
[0068] The second vacuum suction plate 51 is fixed to the rack 1 and can firmly fix the lower substrate, preventing it from moving or deforming during the printing process and affecting the printing quality and product performance. This design ensures the accuracy and consistency of the printing.
[0069] The electrolyte ink fountain 52 of the present embodiment is provided with an electrolyte tank 55 for supplying the gel electrolyte to the electrolyte ink fountain 52, and a second liquid level sensor 56.
[0070] The second liquid level sensor 56 is used to monitor the electrolytic quality of the gel electrolyte in the electrolyte ink fountain 52, wherein the second liquid level sensor 56 is an ultrasonic liquid level sensor.
[0071] The second vacuum suction plate 51 is connected to a vacuum pump.
[0072] The design of the electrolyte tank 55 ensures that the gel electrolyte can be stably and continuously supplied to the electrolyte ink fountain 52, thereby ensuring the uniformity and continuity of the electrolyte layer during printing. This helps to improve the printing quality and overall performance of the product.
[0073] The setting of the second liquid level sensor 56 allows the electrolytic quality of the gel electrolyte in the electrolyte ink fountain 52 to be monitored in real time. When the electrolytic quality is below a preset threshold, the system can automatically issue a warning or trigger a replenishment mechanism, thereby avoiding printing interruptions caused by insufficient electrolyte. This intelligent monitoring function improves the automation and stability of the production line.
[0074] The second vacuum suction plate 51 is connected to a vacuum pump, which can firmly fix the lower substrate and prevent it from moving or deforming during printing, which can affect the printing quality and product performance. This design ensures the accuracy and consistency of printing, which helps to improve the quality of the product.
[0075] The thermal curing mechanism 4 of the present embodiment is an infrared heat dryer, and the UV curing mechanism 6 is a UV curing device.
[0076] By radiating infrared heat energy, the infrared heat dryer can rapidly heat and cure the ink or electrolyte layer in the printing material. This heating method has the characteristics of high efficiency and speed, which can greatly shorten the curing time and improve the production efficiency.
[0077] The UV curing device uses the photochemical reaction of ultraviolet light to rapidly cure the ink or electrolyte layer on the surface of the printing material. UV curing has the advantages of fast curing speed and controllable curing depth, which can meet the curing needs of different materials.
