Description

Technical Field

[0001] This application relates to the technical field of FPC film storage, and in particular to an FPC film storage cabinet. Background Technology

[0002] In the manufacturing process of flexible printed circuit boards (FPC), film is a key consumable in the exposure process and needs to be stored for a long time to avoid scratches, dust contamination or deformation due to moisture.

[0003] Currently, the industry generally uses open shelves or ordinary storage cabinets to store film. The storage cabinets use sliding drawers to store film. During long-term use, the drawers are repeatedly pushed and pulled, making it difficult to guarantee the airtightness of the drawers. As the precision of FPC circuits has improved to the micron level, the impact of the film storage environment on the yield rate has become increasingly significant, requiring further improvement in the airtightness of the storage cabinets. Utility Model Content

[0004] To further improve the sealing performance of the storage cabinet, this application provides an FPC film storage cabinet.

[0005] This application provides an FPC film storage cabinet, which adopts the following technical solution:

[0006] An FPC film storage cabinet includes:

[0007] Cabinet;

[0008] The support plate is installed on the opposite side walls of the cabinet at both ends along its length. The support plate is inclined downward along its length and is spaced apart along the height of the cabinet. The inclination of the upper surface of the support plate is different from that of the lower surface of the support plate.

[0009] A drawer is installed between the two support plates. When the drawer slides down along the inclined support plates and fits against the side wall of the cabinet, the bottom of the drawer fits against the upper surface of the support plate, the opening edge of the drawer fits against the lower surface of the support plate, and a gap is left between the drawer and the other side wall of the cabinet.

[0010] By adopting the above technical solution, the storage cabinet forms a wedge-shaped sealing structure through a double-inclination support plate design (upper surface inclination < lower surface inclination). When the drawer slides down the support plate, the bottom first contacts the upper surface of the support plate. As the sliding distance increases, the edge of the drawer opening gradually comes into contact with the lower surface of the support plate, ultimately forming a three-point seal between the cabinet side wall and the support plate (bottom sealing point + opening edge sealing point + side wall contact point). Compared with the single-plane seal of traditional drawers, this design increases the longitudinal sealing dimension, effectively preventing dust and moisture intrusion; the sealing performance is greatly improved, making it particularly suitable for the stringent storage environment requirements of FPC micron-level processes.

[0011] Optionally, a limiting block is installed on the surface of the inclined lower end of the support plate. When the drawer slides down along the inclined support plate and fits against the side wall of the cabinet, the drawer and the limiting block come into contact.

[0012] By adopting the above technical solution, a limiting block is set at the lower end of the support plate to form a physical stop mechanism. When the drawer is fully pushed in, the limiting block makes surface contact with the rear end of the drawer, preventing the drawer from being pulled out horizontally. The operator must push the drawer upward about 2-3cm along the inclined direction of the support plate to disengage the limiting block from the restraining area before the drawer can be pulled out. This two-step operation mechanism of "lifting first and then pulling" ensures absolute sealing of the storage state and avoids accidental slippage of the drawer due to misoperation, making it particularly suitable for secure storage needs in high-frequency access scenarios.

[0013] Optionally, the limiting block is provided with a guide portion, which is located outside the support plate and is used to guide the drawer to slide between the two support plates.

[0014] By adopting the above technical solution, the guide plate and the support plate of the guide part contact the side wall and bottom of the drawer respectively, which can guide the drawer to smoothly enter between the support plates.

[0015] Optionally, an abutment block is movably installed inside the support plate. When the drawer slides down along the inclined support plate and fits against the side wall of the cabinet, the abutment block abuts against the upper end of the drawer in the inclined direction.

[0016] By adopting the above technical solution, the drawer is positioned by five points (upper and lower sides of the support plate + abutment block + limit block + cabinet side wall), so that the drawer can remain stable in a vibration environment.

[0017] Optionally, the abutment block is connected to a slider, and a groove is provided on the upper surface of the support plate, in which the slider is slidably installed.

[0018] By adopting the above technical solution, the slider and the groove cooperate to stably install the abutment block inside the support plate, and the groove can limit the sliding stroke of the abutment block.

[0019] Optionally, the abutment block extends beyond the support plate.

[0020] By adopting the above technical solution, when the drawer slides in, it can slide between the two support plates along the abutment block, which has a certain guiding effect.

[0021] Optionally, a limiting plate is rotatably installed inside the drawer to secure the film stored inside.

[0022] By adopting the above technical solution, the limiting plate automatically rotates to the locking position, so that when the drawer is placed at an angle, the film is stably installed inside the drawer.

[0023] Optionally, the drawer is connected to a rotating shaft, and the limiting plate is rotatably mounted on the rotating shaft. The limiting plate has a slot for inserting film.

[0024] By adopting the above technical solution, the slot of the limiting plate provides a specific installation position for the film. Rotating the limiting plate causes the film to rotate out of the drawer, making it convenient for people to take out and put in the film.

[0025] In summary, this application includes at least one of the following beneficial effects:

[0026] 1. The support plate features a differentiated inclined design on its upper and lower surfaces, creating a progressive sealing interface. As the drawer slides down the support plate, the bottom of the drawer contacts the edge of the drawer opening, and the side wall contacts, forming a triple sealing barrier.

[0027] 2. The limiting block and the abutment block form a double locking mechanism, creating a five-point constraint (two support surfaces + limiting block + abutment block + side wall) when the drawer is fully pushed in, so that the drawer is stably installed between the two support plates.

[0033] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0034] This application discloses an FPC film storage cabinet.

[0035] Reference Figure 1An FPC film storage cabinet comprises a cabinet body 10, support plates 20, and drawers 30. Its core innovation lies in achieving high-precision sealing through the synergistic effect of the inclined support plates 20 and drawers 30. The cabinet body 10 adopts a rectangular frame structure, with support plates 20 fixedly installed on both side walls. The support plates 20 are inclined downwards along their length. A unique feature of the support plates 20 is their differentiated inclined design on the upper and lower surfaces; the upper surface has a smaller inclination angle, while the lower surface has a larger inclination angle. This design causes the thickness of the support plates 20 to gradually increase from top to bottom, forming a wedge-shaped structure. Multiple support plates 20 are spaced apart along the height of the cabinet body 10, providing multi-level installation positions for the drawers 30.

[0036] Reference Figure 2 and Figure 3 As the main storage unit, drawer 30's unique structure is reflected in its interaction with support plates 20. The relatively large gap between the tops of adjacent support plates 20 facilitates the drawer 30 sliding between them. The bottom of the drawer 30 initially contacts the upper surface of the support plate 20, while a small gap remains between the drawer 30's opening edge and the lower surface of the support plate 20. As the drawer 30 slides downwards along the support plate 20 under its own weight and with manual pushing, the opening edge gradually comes into contact with the lower surface of the support plate 20. Finally, under the influence of gravity, when the drawer 30 is fully seated, the bottom and opening edge of the drawer 30 form two sealing lines with the upper and lower surfaces of the support plate 20, respectively. Simultaneously, the side wall of the drawer 30 contacts the inner wall of the cabinet 10, forming a third sealing point, thus creating a three-point sealing system. Compared to traditional planar sealing, this sealing method increases the vertical sealing effect, effectively preventing dust and moisture intrusion.

[0037] Reference Figure 2 A handle is installed on one side of drawer 30. To ensure stable locking of drawer 30, a limit block 40 is installed on the upper surface of the inclined lower end of support plate 20. When drawer 30 is fully pushed in, the side of drawer 30 with the handle makes surface contact with limit block 40. The physical stop of limit block 40 prevents drawer 30 from being pulled out horizontally. The operator must first slide drawer 30 about 2-3 cm along the inclined direction of support plate 20 to disengage the opening edge of drawer 30 from the constraint of limit block 40 before pulling it out. This "lift then pull" two-step operation mechanism ensures absolute sealing of the storage state and avoids accidental slippage of drawer 30 due to misoperation.

[0038] Reference Figure 2To improve the ease of sliding the drawer 30 into the drawer, a guide section 50 is provided at the front end of the limiting block 40. The guide section 50 consists of a guide plate 51 and a support plate 52. The guide plate 51 is vertically arranged, and the support plate 52 is flush with the upper surface of the support plate 20 and has the same inclination angle. The guide plate 51 and the support plate 52 are joined to form an L-shape. The guide plate 51 is used to contact the side wall of the drawer 30. When the drawer 30 slides in, the guide plate 51 guides the side wall of the drawer 30, and the support plate 52 supports and guides the bottom of the drawer 30, ensuring that the drawer 30 can accurately slide between the two support plates 20 along the support plate 20.

[0039] Reference Figure 2 and Figure 3 To further enhance the stability of drawer 30, an abutment block 60 is movably installed inside support plate 20. The abutment block 60 is connected to a slide groove 21 on the upper surface of support plate 20 via a slider 61. The slide groove 21 extends along the inclined direction of the upper surface of support plate 20, allowing the abutment block 60 to slide along it. When drawer 30 is fully pushed in, the abutment block 60 is manually pushed, and it abuts against the upper end of drawer 30 in the inclined direction. The abutment block 60, together with the limit block 40, the upper and lower surfaces of support plate 20, and the side wall of cabinet 10, form a five-point positioning constraint. The design of the abutment block 60 extending beyond support plate 20 allows it to guide the drawer 30 during sliding in, ensuring accurate placement.

[0040] Reference Figure 4 The drawer 30 is equipped with a film fixing device, including a pivot 70 installed at the bottom of the drawer 30 and a limiting plate 80 installed on the pivot 70. The limiting plate 80 can rotate around the pivot 70, and the limiting plate 80 has a slot 81 that matches the size of the film. When the film is inserted into the slot 81, rotating the limiting plate 80 to the locked position will fix the film. When the film needs to be removed or placed, rotating the limiting plate 80 in the opposite direction will unlock it. This design ensures stable storage of the film and improves access efficiency.

[0041] In summary, this embodiment, through technological innovations such as the double-tilt support plate 20 design, three-point sealing system, physical stop and guide mechanism, five-point positioning constraint, and film fixing device, achieves high-precision sealing, stable storage, and convenient operation of the FPC film storage cabinet. It is particularly suitable for the FPC manufacturing field, which has stringent requirements for storage environment.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
