Description

Technical Field

[0001] This utility model belongs to the field of photomask technology, specifically relating to a photomask box with a positioning structure. Background Technology

[0002] Photomask boxes typically have standardized dimensions and shapes, facilitating transportation and storage between different devices and locations. They can be easily placed in specialized photomask storage cabinets, transport cases, or photomask loading systems of lithography machines, improving operational convenience and efficiency.

[0003] In existing photomask boxes, multiple wafers are usually separated by spacers or arranged vertically when storing wafers. However, neither of these methods can provide comprehensive protection and positioning for the wafers. When the photomask box is subjected to external forces (such as handling, collision, or bumping), the wafers are prone to vibration and slight deformation, which can affect the accuracy of subsequent processing.

[0004] Therefore, a photomask box with a positioning structure is designed to overcome the above-mentioned technical defects. Utility Model Content

[0027] This specific embodiment is a photomask box with a positioning structure, and its structural diagram is shown below. Figures 1-6 As shown, it includes a placement box 1, with a cover plate 2 movably connected to the end face of the placement box 1, and multiple sets of storage components are provided in the inner cavity of the placement box 1; the material of the placement box 1 is the same as that of the existing photomask box.

[0028] The storage unit includes a lower support plate 3 and an upper top plate 4. The left and right side walls of the lower support plate 3 and the upper top plate 4 are respectively provided with snap-fit ​​components. The area between the lower support plate 3 and the upper top plate 4 is a storage area. A positioning component is provided between the lower support plate 3 and the upper top plate 4.

[0029] like Figure 6 As shown, the snap-fit ​​assembly includes two snap-fit ​​blocks 5 fixedly connected to the left and right side walls of the lower support plate 3, and snap-fit ​​hooks 6 corresponding to the snap-fit ​​blocks 5 fixedly connected to the left and right side walls of the upper top plate 4. The bottom surface of the snap-fit ​​hooks 6 is inclined, and when the snap-fit ​​blocks 5 and snap-fit ​​hooks 6 are snapped together, a protrusion is formed.

[0030] Both the locking block 5 and the locking hook 6 can be made of plastic, rubber or other materials, which can produce a certain deformation when subjected to force. When it is necessary to remove the wafer from the placement slot 13, simply push the locking hook 6 on one side upward to disengage it from the locking block 5, and the top plate 4 can be removed, thus making it easy to remove the wafer. Its structure is simple, easy to operate and has a good protective effect on the wafer.

[0031] like Figure 1 and Figure 5 As shown, the positioning component includes a rod 10 fixedly connected to the bottom surface of the upper top plate 4 near the four corners, and a hole 11 corresponding to the rod 10 is opened on the top surface of the lower support plate 3 near the four corners. Two positioning grooves 7 are opened on the left and right inner walls of the placement box 1, and the protrusion is adapted to the positioning groove 7.

[0032] By setting up positioning components, on the one hand, when placing wafers into storage devices, the lower support plate 3 and the upper top plate 4 can be positioned to prevent the card block 5 and the hook 6 from shifting and separating. On the other hand, when placing storage devices into placement boxes 1, the storage devices can be positioned so that multi-layer storage devices can be neatly stacked.

[0033] like Figure 1 and Figure 2As shown, a sponge pad 8 is fixedly connected to the bottom surface of the cover plate 2. The fixing method between the cover plate 2 and the storage box 1 can be other structures such as snap-fit, threaded connection, and lock. When the cover plate 2 is closed, the elasticity of the sponge pad 8 can apply downward pressure to the storage component, reducing the shaking phenomenon.

[0034] like Figure 4 As shown, a placement groove 13 is provided on the top surface of the lower support plate 3, and the placement groove 13 is a storage area.

[0035] A first protective pad 14 is fixedly connected to the bottom surface of the placement slot 13, and a second protective pad 9 is fixedly connected to the bottom surface of the top plate 4. Specifically, the diameter of the placement slot 13 can be set according to the diameter of the wafer. In actual use, different sizes of placement boxes 1 and storage components can be set to accommodate wafers of different specifications.

[0036] Both the first protective pad 14 and the second protective pad 9 are made of sponge, latex or foam. When the lower support plate 3 and the upper top plate 4 are combined, they can form a wrapping structure for the wafer, thereby increasing its stability.

[0037] like Figure 3 As shown, a groove is provided on the top surface of the top plate 4, and a handle 15 is movably connected in the groove. The storage handle 15 can be used to take out and put in the multi-layer storage box 1 in sequence, which is highly practical and flexible.

[0038] like Figure 5 As shown, several rubber blocks 12 are fixedly connected to the bottom surface of the lower support plate 3. The rubber blocks 12 are used to increase the space between each layer of storage components. If the box 1 is subjected to bumps during transportation, the vibration force generated by the bumps can be reduced by each layer of rubber blocks 12, thus protecting the wafer.

[0039] Working principle: First, place the wafers in the placement slots 13. Then, place the upper top plate 4 on the lower support plate 3. At the same time, insert the rod 10 into the insertion hole 11 for positioning. Then, press the upper top plate 4 with a little force. The inclined surface of the hook 6 will expand it outward and apply downward pressure. When the upper top plate 4 and the lower support plate 3 are in contact, the hook 6 moves to the bottom of the locking block 5 and resets, thereby hooking the locking block 5 and fixing the wafers.

[0040] Then, the storage devices containing wafers are placed in the placement box 1 in sequence. The protrusions formed by the card block 5 and the card hook 6 are inserted into the positioning slot 7. After multiple storage devices are stacked in sequence, the cover plate 2 is closed. The sponge pad 8 can be used to squeeze the top storage device, so that the whole is subjected to downward pressure, further increasing stability.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
