Description

Technical Field

[0001] This utility model relates to the field of film storage technology, and in particular to a glass film storage cabinet. Background Technology

[0002] Glass film, as an important optical material, is widely used in printing plate making, photolithography, precision measurement and microelectronics manufacturing. Its excellent optical performance and high-precision imaging capabilities make it an indispensable key material in these fields. However, due to the fragility of glass film and its extreme sensitivity to environmental conditions, specially designed storage cabinets are required to ensure its long-term safety and stability.

[0003] Patent CN207885966U discloses a film storage cabinet. The cabinet includes a cubic body and several drawers. The cabinet body has several drawer slots on one side, arranged parallel to each other from top to bottom. Each drawer corresponds to a drawer slot, and each drawer slides into its corresponding slot. The sides of the drawers are connected to the side walls of the drawer slots via rolling connectors. The cabinet features multiple large, shallow drawers that are easy to push and pull, providing ample space for film storage. It also allows for labeling or categorizing of items stored in the drawers. While ensuring the safe storage of film, this patent still has some shortcomings. Its simple drawer structure design allows glass film to be stored in a flat stack inside the drawer. This storage method is prone to the following problems: due to the adhesive properties of the glass film surface, the stacked film may stick together, causing damage. In addition, when staff need to remove a glass film from a specific location, they need to flip the surrounding film, which is inconvenient and may also cause other film to be accidentally scratched or stained with fingerprints, thus affecting its optical performance and imaging quality.

[0004] Therefore, there is an urgent need to provide a glass film storage cabinet with a drawer structure that features separate storage and easy access to the film. Utility Model Content

[0005] In order to overcome the shortcomings of existing film storage cabinets, which lack separation and protection measures during the storage process of glass film, cannot effectively prevent the film from contacting and sticking together, and do not provide a convenient way to retrieve the film, this utility model provides a glass film storage cabinet with a drawer structure that has a separation storage function and facilitates the retrieval of film.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a glass film storage cabinet, comprising a cabinet body with hinged, sealed doors on both external sides of the cabinet body, a control panel embedded in the upper right side of the cabinet body, and two independent storage spaces inside the cabinet body. Each storage space has multiple tracks installed on its left and right side walls, evenly spaced along the height of the storage space. Each storage space contains multiple placement plates, also evenly spaced along the height, with their ends slidably inserted into adjacent tracks, allowing the placement plates to slide back and forth along the tracks. This design divides the storage space into multiple compartments, each containing a drawer. The drawer is fixedly connected to the placement plate below it. A pivot is installed inside the drawer, with both ends rotatably connected to the inner side walls of the drawer. A placement box is mounted on the pivot, and torsion springs are fitted at both ends of the pivot. One end of the torsion spring is connected to the inner wall of the drawer, and the other end is connected to the outer wall of the placement box. A pressure block is fixed to the bottom of each placement plate, extending into the drawer below and holding the placement box in place. The lower front side of the plate is designed to be curved, and a protective divider bag is provided inside the placement plate.

[0007] Furthermore, the cabinet's storage space has two cavities at the rear, one in front and one behind, connected by multiple square air vents. The front cavity has several air ducts, and the rear wall of the cabinet also has the same air ducts. Multiple first fans are installed inside the rear cavity. Each square air vent has a fixing frame, and the fixing frames correspond one-to-one with the multiple first fans. One side of the fixing frame is equipped with heat dissipation fins, and the other side is equipped with a semiconductor cooling module. Multiple electric heating tubes are installed inside the front cavity.

[0008] Furthermore, a protective cover is provided at the air outlet of the first fan.

[0009] Furthermore, a mounting plate is fixed to the middle position inside the cavity on the front side, and multiple second fans are mounted on the mounting plate. The multiple second fans are arranged in an alternating manner, that is, some blow air upwards and some blow air downwards.

[0010] Furthermore, a label box is provided on the front side of the drawer.

[0011] Furthermore, a sealing gasket is provided at the joint surface between the sealed door and the cabinet.

[0012] Furthermore, the bottom of the cabinet is equipped with multiple casters.

[0013] Furthermore, a temperature sensor is installed at the top of the cabinet.

[0014] Compared with the prior art, the present invention has the following technical effects: 1. By setting up a storage box with a protective divider inside each drawer, multiple glass film sheets can be stored independently, effectively avoiding the adhesion caused by stacking, while reducing the risk of friction and scratches between the sheets, ensuring the integrity of the film sheet surface. In addition, the storage box can automatically spring up to a vertical position by a torsion spring after the drawer is pulled out, so that the glass film sheets are arranged vertically. This design not only facilitates intuitive selection of the required film sheets, but also avoids the situation of rummaging through the surrounding film sheets, thus improving storage and retrieval efficiency.

[0015] 2. By combining the dual-cavity structure at the rear of the cabinet with a semiconductor cooling module, electric heating tube, and fan system, the internal temperature can be dynamically adjusted based on the real-time detection results of the temperature sensor to maintain a constant temperature environment. This design can effectively cope with the impact of temperature fluctuations on the glass film and extend its service life.

[0016] 3. The design of the second fan arranged in alternating directions enables rapid diffusion and uniform distribution of gas within the cabinet, ensuring consistent temperature and humidity conditions in each storage compartment and further improving storage performance.

Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0026] Example 1: Please refer to Figures 1-4A glass film storage cabinet includes a cabinet body 1. Four casters 25 are installed at the bottom of the cabinet body 1, allowing the cabinet to be easily moved to different positions, improving the flexibility and applicability of the equipment. Sealing doors 3 are hinged to the left and right sides of the cabinet body 1 via hinges 2. Sealing gaskets 24 are provided at the joint surfaces of the sealing doors 3 and the cabinet body 1 to enhance the sealing performance of the cabinet body 1 and effectively prevent external dust, moisture, and other contaminants from entering the cabinet body 1. A control panel 4 is embedded in the upper right side of the cabinet body 1 for adjusting the internal environment of the cabinet body 1. The cabinet body 1 has two independent storage spaces, left and right. Nine tracks 5 are installed on the left and right side walls of each storage space, evenly spaced along the height of the storage space. Nine placement plates 6 are configured inside each storage space, also evenly spaced along the height, and slidably inserted into adjacent tracks 5 at their left and right ends, allowing the placement plates 6 to slide back and forth along the tracks 5, thereby dividing the storage space into multiple storage compartments. Each storage compartment contains a drawer. Drawer 7 is fixedly connected to the placement plate 6 below. A label box 23 is provided on the front side of drawer 7 to facilitate user marking and identification of the film information stored in drawer 7, helping staff to quickly and accurately find the required glass film, improving work efficiency and contributing to orderly management. A rotating shaft 8 is installed inside drawer 7, with both ends of the shaft 8 rotatably connected to the left and right side walls inside drawer 7. A placement box 9 for holding glass film is installed on the rotating shaft 8, and the placement box 9 can be rotated via the rotating shaft 8. In operation, torsion springs 10 are fitted at both ends of the rotating shaft 8. One end of the torsion spring 10 is connected to the inner wall of the drawer 7, and the other end is connected to the outer wall of the placement box 9, providing the placement box 9 with a constant upward rotational torque. Each placement plate 6 has a pressure block 11 fixed to its bottom. The pressure block 11 extends into the drawer 7 below and keeps pressing down on the placement box 9. Furthermore, its lower front side is designed to be arc-shaped. The placement plate 6 has a partition protective bag 12 inside, which is used to separate the glass film sheets so that the glass film sheets can be placed and stored independently.

[0027] Initially, the placement box 9 lies flat inside the drawer 7. At this time, the torsion spring 10 is compressed and held in place by the pressure block 11. When it is necessary to insert or remove the glass film, the operator pulls the corresponding drawer 7 outwards. The placement plate 6 moves forward along the track 5, providing guidance. As the drawer 7 is pulled out, the placement box 9 moves in front of the pressure block 11, its top disengaging from the block and no longer being pressed down. Then, under the restoring force of the torsion spring 10, the placement box 9 rotates upwards at a certain angle, becoming upright. This design ensures that when inserting the glass film, the opening of the protective bag 12 faces upwards, facilitating operation. The presence of the protective divider bag 12 ensures that multiple glass film sheets can be stored independently, effectively preventing them from sticking together when stacked. When a glass film sheet is taken out, the glass film sheets inside become vertically arranged because the placement box 9 is upright, making it easy to quickly select and take out the glass film sheet in a specific position, while avoiding disturbing the surrounding film sheets. After the operation is completed, the staff needs to press the upright placement box 9 back into the drawer 7, so that the torsion spring 10 is compressed again, and then push the drawer 7 back into place. During this process, the arc-shaped part of the pressure block 11 can guide the placement box 9 back under the pressure block 11, so that the pressure block 11 presses down on the placement box 9 again, preventing it from accidentally popping up due to the action of the torsion spring 10.

[0028] Example 2: Based on Example 1, please refer to... Figure 5 and Figure 6 The cabinet 1 has two cavities 13 on the rear side of its storage space, and the two cavities 13 are connected by four square air vents 1301. The front cavity 13 has several air ducts 14 for introducing cold or hot air into the storage space, and the rear wall of the cabinet 1 also has the same air ducts 14 for introducing outside air into the rear cavity 13. Four first fans 15 are installed inside the rear cavity 13 to extract hot air. The exhaust end of each first fan 15 is equipped with a protective cover 22 to prevent external impurities or foreign objects from entering the first fan 15, thus avoiding damage or disruption to its normal operation due to foreign object inhalation. The square air vent 1301 is equipped with a fixed frame 16. The four fixed frames 16 correspond one-to-one with the four first fans 15. One side of the fixed frame 16 is equipped with a heat dissipation fin 17, and the other side is equipped with a semiconductor cooling module 18 for generating cold air. The cavity 13 on the front side is equipped with four electric heating tubes 21 for generating hot air. A temperature sensor 26 is installed on the top of the cabinet 1 for real-time monitoring of temperature changes inside the cabinet and transmitting the detected data to the control panel 4 so that the working status of the semiconductor cooling module 18, the first fan 15, the second fan 20 and the electric heating tubes 21 can be automatically adjusted according to the set parameters to maintain a constant temperature condition inside the cabinet.

[0029] Please see Figure 5 and Figure 7 A mounting plate 19 is fixed to the middle position inside the cavity 13 on the front side. Four second fans 20 are mounted on the mounting plate 19. The four second fans 20 are arranged in a staggered manner, that is, some blow air upward and some blow air downward, which is used to enhance the gas flow in the vertical direction inside the cavity 13 and accelerate gas diffusion.

[0030] During the storage of the glass film, the internal temperature of the cabinet 1 is monitored in real time by the temperature sensor 26. If the internal temperature of the cabinet 1 is detected to be too high, the semiconductor cooling module 18 is activated. At this time, the side of the semiconductor cooling module 18 near the front cavity 13 absorbs heat to achieve cooling, cooling the outside air entering from the air guide groove 14 on the rear cavity 13. At the same time, the other side releases heat, which is absorbed by the heat dissipation fins 17 and discharged to the outside through the first fan 15. The cold air generated by the semiconductor cooling module 18 enters the front cavity 13 through the square air guide 1301 and flows from the air guide groove 14 of the front cavity 13. Simultaneously, the second fan 20 starts, rapidly distributing cool air throughout the front cavity 13, ensuring that the cool air is evenly filled into the storage space of the cabinet 1 for cooling. If the internal temperature of the cabinet 1 is detected to be too low, the semiconductor cooling module 18 and the first fan 15 are turned off, and the electric heating tube 21 is turned on to generate hot air to heat the storage space inside the cabinet 1. During this process, the second fan 20 continues to work to help distribute the hot air evenly throughout the storage space. In this way, through the above mechanism, it can be ensured that the inside of the cabinet 1 maintains a constant temperature environment, providing the best storage conditions for the glass film.
