Description

Technical Field

[0001] This utility model belongs to the field of silicon wafer cassette technology, and in particular relates to a silicon wafer cassette with anti-rollover function. Background Technology

[0002] Silicon wafers, as a core material in semiconductor chip manufacturing and photovoltaic module production, are brittle and thin with extremely high surface precision requirements. During storage, transportation, and workshop circulation, stringent requirements are placed on the stability and protection of silicon wafer cassettes. Currently, most silicon wafer cassettes widely used in the industry employ a basic structural design with a single cassette body and a bottom anti-slip pad, achieving initial positioning only through the contact between the bottom of the cassette body and the placement surface.

[0003] However, existing silicon wafer cassettes lack stable support mechanisms on both sides. Most products rely solely on the weight of the cassette itself for balance. When the placement surface is slightly tilted, such as due to local deformation of the workshop workbench after long-term use, the tilting of the transport trolley during travel, or slight external collisions or vibrations, the cassette is prone to tipping to one side due to the shift in the center of gravity. This causes the internal silicon wafers to squeeze and rub against each other, which can not only scratch the precision coating on the surface of the silicon wafers, but may also cause the silicon wafers to break, directly affecting the yield of subsequent processing and increasing production costs.

[0004] To address these issues, we provide a silicon wafer cassette with anti-rollover functionality. Utility Model Content

[0005] The purpose of this utility model is to provide a silicon wafer cassette with an anti-rollover function. Through the action of the bracket, the bracket is set at an angle, with one end fixed to the connecting shell and the other end connected to the positioning plate. When the slider slides into the sliding grooves on both sides of the silicon wafer cassette body, the angled bracket can form a triangular support structure with the silicon wafer cassette body, which can stably support the silicon wafer cassette body from both sides, directly preventing it from tipping over or falling over during placement. This solves the problem that existing silicon wafer cassettes lack a stable support mechanism on both sides, and most products rely solely on the weight of the cassette body for balance. When the placement surface is slightly tilted, such as due to local deformation of the workshop operating table after long-term use, the bumps and tilts of the transport trolley during travel, or slight external collisions or vibrations, the cassette body is prone to tipping to one side due to the shift of the center of gravity.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a silicon wafer box with anti-roll function, including a silicon wafer box body, and a number of partitions are fixed on the inner wall of the silicon wafer box body; Mounting plates are fixed on both sides of the silicon wafer cassette body; Both sides of the silicon wafer box body are fixed with sliding grooves, and a slider is slidably connected inside the sliding grooves; A connecting plate is fixed to one side of the slider, and a mounting shell is fixed to the surface of the connecting plate; Positioning grooves are provided on both sides of the mounting shell; The mounting housing is movably connected to a connecting shell, a bracket is fixed to one side of the connecting shell, and a positioning plate is fixed to one end of the bracket.

[0007] The present invention is further configured such that: the bracket is inclined, and the bottom of the positioning plate is fixed with several anti-slip blocks.

[0008] The present invention is further configured such that: the slider is a "T" shaped structure, and the slider matches the inner wall of the groove.

[0009] The present invention is further configured such that: a fixing plate is fixed inside the connecting shell, and a first telescopic rod is fixed on both sides of the fixing plate; A spring is sleeved on the outside of the first telescopic rod, and a movable plate is fixed to one end of the first telescopic rod. A locking block is fixed to one side of the movable plate, the locking block penetrates the connecting shell, and the locking block penetrates the positioning groove.

[0010] The present invention is further configured such that: a second telescopic rod is fixed on both sides of the connecting plate, and a tension spring is sleeved on the outer side of the second telescopic rod; A handle is fixed to one end of the second telescopic rod; One end of the tension spring is fixedly connected to the handle, and the other end of the tension spring is fixedly connected to the connecting plate.

[0011] The present invention is further configured such that a locking rod is fixed to one end of the handle; Both sides of the silicon wafer box body are fixed with positioning strips, and the surface of the positioning strips has several card holes. One end of the lever is inserted into the locking hole.

[0012] The present invention is further configured such that: the surface of the mounting plate has mounting holes; A threaded rod passes through the mounting hole, and a cover plate is fixed to one end of the threaded rod; The outer ring of the threaded rod is threaded with several threaded tubes.

[0013] This utility model has the following beneficial effects: 1. This utility model utilizes a bracket that is inclined, with one end fixed to the connecting shell and the other end connected to a positioning plate. When the slider slides into the grooves on both sides of the silicon wafer box body, the inclined bracket forms a triangular support structure with the silicon wafer box body, providing stable support from both sides and directly preventing it from tipping over or falling over during placement. A positioning plate is fixed to the end of the bracket, and several anti-slip blocks are provided at the bottom of the positioning plate. The bracket uses its own supporting force to make the positioning plate fit tightly against the placement surface. The anti-slip blocks can increase the friction between the positioning plate and the placement surface, further reducing the risk of the silicon wafer box body rolling over due to slight sliding and enhancing the overall placement stability.

[0014] 2. This utility model utilizes the action of the locking rod. When the silicon wafer box body is placed on an uneven surface, pulling the handle causes the locking rod to disengage from the locking hole, allowing the connecting plate to move up and down. This, in turn, moves the bracket and positioning plate to adjust their height until both positioning plates on both sides can stably contact the placement surface and the silicon wafer box body remains horizontal. Then, the locking rod is fixed by cooperating with the corresponding locking hole, allowing the device to adapt to placement scenarios with different flatness levels and solving the problem that a single height support cannot cope with uneven surfaces.

[0025] For a specific implementation example, please refer to Implementation Example 1. Figures 1-5 This utility model is a silicon wafer cassette with anti-rollover function, including a silicon wafer cassette body 1, with several partitions 2 fixed on the inner wall of the silicon wafer cassette body 1; mounting plates 3 are fixed on both sides of the silicon wafer cassette body 1; sliding grooves 4 are fixed on both sides of the silicon wafer cassette body 1, and sliders 5 are slidably connected inside the sliding grooves 4; a connecting plate 6 is fixed on one side of the slider 5, and a mounting shell 7 is fixed on the surface of the connecting plate 6; positioning grooves 8 are opened on both sides of the mounting shell 7; a connecting shell 9 is movably connected inside the mounting shell 7, and a bracket 10 is fixed on one side of the connecting shell 9, with a positioning plate 11 fixed at one end of the bracket 10.

[0026] Specifically, the bracket 10 is tilted, and the bottom of the positioning plate 11 is fixed with several anti-slip blocks 12. The slider 5 has a "T" shaped structure and matches the inner wall of the groove 4.

[0027] Furthermore, a fixing plate 13 is fixed inside the connecting shell 9, and a first telescopic rod 14 is fixed on both sides of the fixing plate 13; a spring 15 is sleeved on the outside of the first telescopic rod 14, and a movable plate 16 is fixed at one end of the first telescopic rod 14; a locking block 17 is fixed on one side of the movable plate 16, the locking block 17 penetrates the connecting shell 9, and the locking block 17 penetrates the positioning groove 8.

[0028] The operation process of this embodiment is as follows: When it is necessary to install the bracket 10 and the positioning plate 11, press the locking blocks 17 on both sides of the connecting shell 9 simultaneously by hand. At this time, the first telescopic rod 14 is compressed and the spring 15 is compressed and stored. Push the connecting shell 9 into the opening of the mounting shell 7 until the connecting shell 9 is completely embedded in the mounting shell 7. Release the hand that pressed the locking block 17, the spring 15 releases the stored force, pushes the first telescopic rod 14 to reset, and then drives the movable plate 16 and the locking block 17 to pop outward, so that the locking block 17 passes through the positioning grooves 8 on both sides of the mounting shell 7, and completes the fixation of the connecting plate 6 and the connecting shell 9. The silicon wafer cassette body 1 has sliding grooves 4 fixed on both sides. The slider 5 on one side of the connecting plate 6 has a "T" shaped structure and matches the inner wall of the sliding groove 4. Align the slider 5 with the entrance of the sliding groove 4 and push it smoothly along the length of the sliding groove 4 until the slider 5 slides to the appropriate position of the sliding groove 4. At this time, the inclined bracket 10 fixed on one side of the connecting shell 9 and the silicon wafer cassette body 9 are aligned. The wafer cassette body 1 forms a triangular support structure. Several anti-slip blocks 12 at the bottom of the positioning plate 11 at the end of the bracket 10 contact the placement surface. The anti-slip blocks 12 increase the friction and prevent the wafer cassette body 1 from easily rolling over. In this device, the bracket 10 is set at an angle, with one end fixed to the connecting shell 9 and the other end connected to the positioning plate 11. When the slider 5 slides into the sliding grooves 4 on both sides of the wafer cassette body 1, the inclined bracket 10 can form a triangular support structure with the wafer cassette body 1, which can provide stable support for the wafer cassette body 1 from both sides, directly preventing it from tipping over or falling over during placement. The positioning plate 11 is fixed at the end of the bracket 10, and several anti-slip blocks 12 are provided at the bottom of the positioning plate 11. The bracket 10 uses its own supporting force to make the positioning plate 11 fit tightly against the placement surface. The anti-slip blocks 12 can increase the friction between the positioning plate 11 and the placement surface, further reducing the risk of the wafer cassette body 1 rolling over due to slight sliding, and strengthening the overall placement stability.

[0029] For a specific embodiment two, please refer to Figures 1-3 Based on the first specific embodiment, a second telescopic rod 18 is fixed on both sides of the connecting plate 6, and a tension spring 19 is sleeved on the outside of the second telescopic rod 18; a handle 20 is fixed to one end of the second telescopic rod 18; one end of the tension spring 19 is fixedly connected to the handle 20, and the other end of the tension spring 19 is fixedly connected to the connecting plate 6.

[0030] Specifically, a locking rod 21 is fixed to one end of the handle 20; positioning strips 22 are fixed to both sides of the silicon wafer box body 1, and several locking holes 23 are opened on the surface of the positioning strips 22; one end of the locking rod 21 is inserted into the locking hole 23.

[0031] Furthermore, the mounting plate 3 has mounting holes 24 on its surface; a threaded rod 25 passes through the mounting hole 24, and a cover plate 26 is fixed to one end of the threaded rod 25; several threaded tubes 27 are threadedly connected to the outer ring of the threaded rod 25.

[0032] The operation process in this embodiment is as follows: When loading silicon wafers into the silicon wafer cassette body 1, locate the mounting plates 3 on both sides of the silicon wafer cassette body 1. The mounting plates 3 have mounting holes 24 on their surfaces. Threaded rods 25 pass through the mounting holes 24 and are connected to several threaded tubes 27 by threads on their outer rings. One end of the threaded rod 25 is fixed to a cover plate 26. Several partitions 2 are fixed to the inner wall of the silicon wafer cassette body 1. The partitions 2 divide the space inside the cassette into independent storage areas. Place the silicon wafers to be stored one by one into the areas between the partitions 2, ensuring that the silicon wafers are placed stably without stacking or tilting. Replace the cover plate 26, allowing the threaded rods 25 to re-pass through the mounting holes 24 of the mounting plates 3, and then screw in the threaded tubes 27 until the cover plate 26 is tightly fitted to the silicon wafer cassette body 1, completing the sealing and fixing of the silicon wafers. If the placement surface is uneven, the sides need to be adjusted. The height of the positioning plate 11 ensures that the silicon wafer cassette body 1 is level, enhancing the anti-rollover effect. Pulling the handle 20 outward stretches the second telescopic rod 18, causing the tension spring 19 to be stretched and stored. Simultaneously, the locking rod 21 is pulled out of the locking hole 23 of the positioning strip 22, releasing the height lock of the connecting plate 6. Pulling the handle 20 up and down causes the connecting plate 6, mounting shell 7, connecting shell 9, and positioning plate 11 to move synchronously along the slide groove 4. The slider 5 slides along the slide groove 4 with the connecting plate 6. During the process, observe the level of the silicon wafer cassette body 1 to ensure that the height of the positioning plates 11 on both sides is adapted to the undulation of the placement surface, so that the silicon wafer cassette body 1 has no tendency to tilt. When the positioning plates 11 on both sides move to the appropriate height, that is, when the silicon wafer cassette body 1 is level and the anti-slip slider 12 is in close contact with the placement surface, release. Opening handle 20 releases the stored force of spring 19, pulling the second telescopic rod 18 to reset, causing the locking rod 21 to move inward and engage with the corresponding height locking hole 23 on the positioning strip 22, thus fixing the height of the connecting plate 6. At this time, the silicon wafer cassette body 1 can still be placed stably on uneven surfaces, and the anti-rollover function is effective. In this device, one end of the locking rod 21 is fixed to handle 20, and the positioning strip 22 is fixed to both sides of the silicon wafer cassette body 1 and has several locking holes 23 on its surface. The two work together to lock the height of the connecting plate 6. When the connecting plate 6 is adjusted to a suitable position and handle 20 is released, under the reset force of the spring 19 on the outside of the second telescopic rod 18, the locking rod 21 will accurately engage with the corresponding locking hole 23 on the positioning strip 22, preventing the connecting plate 6 from sliding up and down due to external force or its own weight. To ensure the stability of the support position of the bracket 10 and the positioning plate 11, and to prevent the silicon wafer box body 1 from losing its anti-rollover effect due to the displacement of the support components; the several locking holes 23 on the surface of the positioning strip 22 form a multi-level adjustment range, which, together with the locking rod 21 that can move with the handle 20, can flexibly adjust the height of the connecting plate 6. When the silicon wafer box body 1 is placed on an uneven surface, by pulling the handle 20 to disengage the locking rod 21 from the locking hole 23, the connecting plate 6 can be moved up and down, which drives the bracket 10 and the positioning plate 11 to adjust the height until both sides of the positioning plate 11 can stably contact the placement surface and the silicon wafer box body 1 remains horizontal. Then, the locking rod 21 is fixed by cooperating with the corresponding locking hole 23, so that the device can adapt to placement scenarios with different flatness and solve the problem that a single height support cannot cope with uneven surfaces.
