[0019] This invention provides a four-in-one foam box for silicon wafer packaging. It has the following beneficial effects:

[0020] 1. This four-in-one foam box for silicon wafer packaging, by setting up a hybrid packaging module, uses elastic partitions to reduce the space occupied by the internal partitions while using the hollow structure of the partitions to further increase the usable space inside the box. Combined with a hybrid placement rack, the elastic deformation absorbs the vibration and impact during transportation, increasing the number of silicon wafers that can be loaded in a single box, thereby improving the space utilization rate of the foam box. At the same time, it improves the protective effect of the foam box on the silicon wafers, and can reduce packaging production and procurement costs through the recycling of the hybrid partition components.

[0021] 2. This four-in-one foam box for silicon wafer packaging uses a frame packaging component to load silicon wafers by combining sub-boxes with the frame. This increases the overall silicon wafer loading capacity and packaging stability of the box. At the same time, it allows for flexible placement of independent sub-boxes according to the actual cargo space, thereby increasing the carrying capacity of a single shipment. This improves the utilization rate of the box's internal space and the cargo space, thus reducing transportation costs.

[0022] 3. This four-in-one foam box for silicon wafer packaging improves the convenience of the silicon wafer packaging process by setting a sliding and stable frame in conjunction with a base plate, thereby optimizing the packing process. The detachable combined shell and stable frame further reduce the packing difficulty and improve packing efficiency. At the same time, the slight sliding of the stable frame during transportation offsets the vibration and impact during transportation, thereby improving the protection of the silicon wafer.

[0023] 4. This four-in-one foam box for silicon wafer packaging, through the support strips on the bottom plate of the foam box and the rectangular blind holes reserved on the top of the module, realizes the vertical connection between the boxes when stacked. While reducing the height of the stacked boxes, increasing the loading capacity and simplifying the packaging process, it also reduces the risk of the boxes tipping over, thereby improving the protection of the silicon wafers.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0040] Example 1, please refer to Figure 1-5The present invention provides a technical solution: a four-in-one foam box for silicon wafer packaging, including a foam box bottom plate 1, the foam box bottom plate 1 being made of polyethylene foam, the foam box bottom plate 1 including a plate body 11, two support strips 12 being fixedly connected to the bottom of the plate body 11, a trapezoidal groove being provided on the top of the plate body 11, and a mixed packaging module being fixedly connected to the top of the plate body 11.

[0041] The hybrid packaging module includes an integrated shell 2 and a hybrid partition component 3, which are used to improve the utilization of packaging space by combining horizontally placed silicon wafers with flatly placed silicon wafers. The integrated shell 2 is used to absorb external impacts from the outside to protect the silicon wafers. The integrated shell 2 includes a main shell 21, which has a hollow structure inside. A trapezoidal protrusion is fixedly connected to the bottom of the main shell 21. The bottom of the main shell 21 is inserted into the trapezoidal groove at the top of the plate 11 through the trapezoidal protrusion. The main shell 21 has a hollow structure inside. A rectangular sliding groove is opened on the front of the main shell 21. Rectangular through holes are connected to the front, back, left and right sides of the main shell 21. Triangular blind holes are opened on the front and back of the inner wall of the main shell 21 to improve the structural strength of the main shell 21. A sliding cover 22 is slidably connected to the top of the main shell 21 through a rectangular sliding groove. Two rectangular blind holes are opened on the top of the sliding cover 22. The size of the rectangular blind holes is the same as that of the support strip 12. The hybrid partition component 3 is inserted inside the main shell 21. The integrated shell 2 is made of polyethylene foam.

[0042] The hybrid partition assembly 3 includes a flexible four-part plate 31 and a hybrid placement rack 33 disposed within the partition space of the flexible four-part plate 31. The top of the flexible four-part plate 31 has a hexagonal through-hole for providing installation compression space and absorbing impact vibration. The flexible four-part plate 31 is located inside the main enclosure 21. The flexible four-part plate 31 includes a longitudinal hollow plate 311. The front of the longitudinal hollow plate 311 is inserted into a rectangular through-hole on the back of the main enclosure 21, and the front of the longitudinal hollow plate 311 is inserted into a rectangular through-hole on the front of the main enclosure 21. A transverse hollow plate is inserted into a rectangular through-hole on the left side of the main enclosure 21. Plate 312, the front of the transverse hollow plate 312 is inserted into the longitudinal hollow plate 311, and the right side of the transverse hollow plate 312 is inserted into the rectangular through hole on the right side of the main shell 21. The longitudinal hollow plate 311, the transverse hollow plate 312 and the inner wall of the main shell 21 form four compartments. The front, back and left and right sides of the main shell 21 are all fitted with fixing rubber straps 32. The fixing rubber straps 32 are used to reinforce the main shell 21 and the elastic quarter plate 31. The elastic quarter plate 31 and the fixing rubber straps 32 are both made of rubber to achieve reusability and improve the stability of the packaging.

[0043] The hybrid placement rack 33 includes a frame 331 made of plastic for reusability. The frame 331 is located in the compartment of the main enclosure 21. A C-shaped plate is fixedly connected to the top of the frame 331. An elastic partition plate 332 is fixedly connected inside the C-shaped plate. Semi-circular rubber strips are fixedly connected to the top and bottom of the elastic partition plate 332. The elastic partition plate 332 and the C-shaped plate of the frame 331 form a horizontal placement compartment. The back of the C-shaped plate, the longitudinal hollow plate 311, and the transverse hollow plate 312 form a transverse placement compartment. There are four hybrid placement racks 33, which are placed in the four compartments of the main enclosure 21 respectively.

[0044] In use, before packaging, the silicon wafers need to be individually packaged according to the internal partition dimensions of the mixing placement rack 33, and then initially packaged with film. After the initial packaging is completed, the mixing placement rack 33 is removed from the main housing 21. After removing the mixing placement rack 33, the packaged silicon wafers are placed into the partitions at the bottom and top of the elastic partition plate 332 respectively. After placement, the mixing placement rack 33 is put back into the partition compartment inside the main housing 21. After the mixing placement rack 33 is put into the partition compartment inside the main housing 21, it compresses the elastic partition plate 31 and the inside of the main housing 21. After being squeezed, the elastic quarter plate 31 undergoes elastic deformation, compressing the hexagonal through-hole space inside it while applying a reverse elastic force to the mixing placement rack 33. At the same time, after being squeezed, the fixing rubber band 32 also applies a reverse elastic force to the mixing placement rack 33 through the main enclosure 21. Thus, without damaging the silicon wafer, the silicon wafer inside the main enclosure 21 is stably fixed. Then, the remaining packaged silicon wafers are placed in the partition between the C-shaped plate and the longitudinal hollow plate 311 of the rack 331. Then, the sliding cover 22 is slidably installed into the top of the main enclosure 21 to complete the boxing.

[0045] During stacking and loading, in the vertical direction, the support strips 12 of the upper foam box are inserted into the rectangular blind hole at the top of the sliding cover 22 of the lower foam box to achieve a stable connection. During transportation, the vibration transmitted to the foam box is mainly absorbed by the main enclosure 21, the elastic quarter plate 31 and the hybrid placement rack 33, thereby protecting the silicon wafer.

[0047] The frame packaging module includes a combined frame 4 and sub-divider boxes 5. These sub-divider boxes work in conjunction with the frame to flexibly load the packaged foam boxes into the cargo space. This improves the utilization rate of the packaging space and, by improving the utilization rate of the cargo space, increases the quantity of goods transported and reduces transportation costs. The combined frame 4 includes a main frame 41, which includes a bottom frame 411. Trapezoidal protrusions are fixedly connected inside the bottom frame 411, and the bottom frame 411 is inserted into the trapezoidal grooves of the plate 11 via these protrusions. A cross plate is fixedly connected to the top of the bottom frame 411, and triangular prisms are fixedly connected to the four corners of the top of the cross plate.

The dividing box 51 is located at the bottom of the top frame 42. The bottom of the dividing box 51 is placed on the base inside the main frame 41. There are a total of four sub-dividing boxes 5.

[0049] In use, the silicon wafers are initially packaged with a film before being boxed.

After all four base positions at the bottom of the main frame 41 are filled with sub-partition boxes 5, the top frame 42 is inserted into the top of the main frame 41 through the support strip 12. After the insertion is secure, it can be stacked and loaded onto the vehicle. After loading, the sub-partition boxes 5 can be placed separately in the cargo space according to the remaining space size to increase the amount of silicon wafers transported in a single trip. During transportation, the combined frame 4 and the sub-partition boxes 5 absorb the impact and vibration during transportation. The polymer skeleton 414 is inside the combined frame 4 to maintain the structural stability of the entire combined frame 4.

[0050] Example 3, please refer to Figure 10-13 The present invention provides a third technical solution: a four-in-one foam box for silicon wafer packaging, including a foam box bottom plate 1, the foam box bottom plate 1 being made of polyethylene foam, the foam box bottom plate 1 including a plate body 11, a rectangular sliding groove being provided on the top of the plate body 11, two support strips 12 being fixedly connected to the bottom of the plate body 11, a trapezoidal groove being provided on the top of the plate body 11, and a sliding packaging module being fixedly connected to the top of the plate body 11;

[0051] The sliding packaging module includes a combined outer shell 6 and a stable frame 7, which are used to improve the vertical placement of silicon wafers, thereby increasing the utilization of internal space and enhancing the reliability of the foam box in protecting the silicon wafers. The combined outer shell 6 is made of polyethylene foam and includes a long side panel 61. Trapezoidal blocks are fixedly connected to the top and bottom of the long side panel 61. The bottom of the long side panel 61 is inserted into the top of the plate 11 through the trapezoidal blocks. Two symmetrically distributed rectangular slots are opened on the back of the long side panel 61. There are two long side panels 61, which are symmetrically distributed about the top of the plate 11. A wide side panel 62 is inserted into the back of the long side panel 61 through the trapezoidal slots. The wide side panel 62 includes a panel body 621. Both the front and back sides are inserted into the rectangular slots of the long side panel 61. The top and bottom of the panel body 621 are fixedly connected with trapezoidal protrusions. The bottom of the panel body 621 is inserted into the trapezoidal slot at the top of the plate body 11 through the trapezoidal protrusions. The back of the panel body 621 is fixedly connected with an isolation strip 622, which is used to form a gap between the inside of the box and the outside of the silicon wafer. There are two wide side panels 62, which are symmetrically distributed on the left and right sides of the plate body 11. The top of the long side panel 61 is inserted into the top of the trapezoidal protrusions. The bottom of the top panel 63 is inserted into the trapezoidal protrusions at the top of the wide side panel 62. The top of the top panel 63 has two symmetrically distributed rectangular blind holes. The size of the rectangular blind holes is the same as that of the support strip 12.

[0052] The stabilizing frame 7 is made of polyethylene foam. The stabilizing frame 7 includes a recessed base 71. The bottom of the recessed base 71 is slidably connected to a rectangular groove on the top of the plate 11. A rectangular blind hole is opened on the top of the recessed base 71 for placing silicon wafers. Two support side plates 72 are fixedly connected to the top of the recessed base 71 and are symmetrically distributed on the top of the recessed base 71. Two triangular through holes are connected to the front of the support side plates 72 to reduce weight and improve structural strength. A top cover 73 is inserted into the top of the support side plates 72. There are four stabilizing frames 7, which are evenly arranged inside the combined shell 6. The stabilizing frames 7 are used to stabilize the vertically placed silicon wafers and offset the vibration during transportation by slight sliding.

[0053] In use, the silicon wafers are initially packaged with a thin film before being boxed. After initial packaging, the top cover 73 is opened, and the packaged silicon wafers are placed into the stabilizing frame 7 from the top of the support side plate 72, allowing the silicon wafers to be placed vertically on the top of the recessed base 71. Then, the top cover 73 is reset, and the silicon wafers are initially fixed vertically by the cooperation of the top cover 73 and the recessed base 71. After the silicon wafers are installed into the stabilizing frame 7, the bottom of the recessed base 71 slides into the rectangular groove at the top of the plate 11. Then, the four stabilizing frames 7 are slid into the top of the plate 11 in sequence. After the arrangement is completed, the long side plate 61 and the wide side plate 6 are inserted. 2. The top of the board 11 is then inserted, and the top panel 63 is then inserted into the top of the long side panel 61 and the wide side panel 62 to complete the boxing process. During the stacking and loading process, the support strip 12 at the bottom of the upper foam box is inserted into the rectangular through hole at the top of the wide side panel 62 of the lower foam box. During transportation, the stabilizing frame 7 slides slightly along the rectangular groove at the top of the board 11 under the fluctuation of the transportation equipment to offset the vibration impact. Since the silicon wafer is in the rectangular blind hole at the top of the recessed base 71 and there is a certain gap between it and the silicon wafer of the adjacent stabilizing frame 7, there will be no collision that causes the silicon wafer to break.
