Description

A waffle box carrier Technical Field

[0001] This utility model relates to the field of chip mounting technology, specifically to a waffle box carrier. Background Technology

[0002] Chip packaging is a crucial step in semiconductor manufacturing. Its main purpose is to assemble qualified chips and components onto a carrier, form electrical connections using appropriate interconnect technologies, and install a casing to ultimately create a complete and effective assembly. During chip packaging, automated pick-and-place machines are used to remove electronic components (such as chips) from the feeding device and place them on designated locations on the printed circuit board (PCB) with high precision and speed.

[0003] To achieve efficient chip placement, chips are typically stored and transported in the form of wafers or waffle cassettes. Wafers are suitable for high-volume production because they can efficiently place and transport large numbers of chips; while waffle cassettes are mainly used in multi-variety, small-batch production scenarios because they can flexibly accommodate chips of different sizes and quantities. However, in practical applications, various equipment is often only equipped with loading mechanisms that support standard wafer rings, while waffle cassette placement usually requires a dedicated waffle cassette loading platform or a static waffle cassette support. These configurations have the following main problems:

[0004] 1. High equipment cost: In order to support the loading of wafers and waffle boxes at the same time, the equipment needs to be configured with a wafer loading platform and a waffle box unloading platform or static bracket, which significantly increases the procurement cost of the equipment.

[0005] 2. Low space utilization: Waffle box loading platforms or static supports are usually fixed in a specific location on the equipment and are not compatible with wafer loading platforms. This fixed configuration not only occupies valuable space on the equipment but also limits its flexibility.

[0006] 3. Low placement efficiency: Compared with wafer loading platforms, waffle box placement platforms or static supports usually lack mobility, resulting in slower placement speeds and making it difficult to meet the needs of high-efficiency production.

[0007] Therefore, there is a need to provide a waffle box carrier that is compatible with wafer loading platforms. Summary of the Invention

[0008] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects in the prior art, which require separate configuration of wafer loading platform and waffle box unloading platform in order to support wafer and waffle box loading at the same time, thus significantly increasing the equipment procurement cost; at the same time, the waffle box unloading platform usually needs to be fixed in a specific position of the equipment, which not only occupies valuable space of the equipment, but also lacks mobility, resulting in slow mounting speed and difficulty in meeting the needs of high-efficiency production. Therefore, this utility model provides a waffle box carrier that is compatible with the wafer loading platform.

[0009] Therefore, this utility model provides a waffle box carrier, comprising:

[0010] The material feeding tray has a flat surface;

[0011] The baffle structure includes horizontal baffles and vertical baffles integrally formed on the feeding tray placement surface; each of the horizontal baffles extends in the horizontal direction and is arranged parallel to each other in the vertical direction; a plurality of vertical baffles are provided between each two adjacent horizontal baffles, the vertical baffles extending in the vertical direction and being arranged parallel to each other in the horizontal direction; the horizontal baffles cooperate with the vertical baffles to divide the placement surface into a plurality of slots for placing waffle boxes; a clearance hole is provided on the feeding tray between one end of the vertical baffle and the horizontal baffle;

[0012] Several rubber strips, made of elastic material, are detachably installed on the inner wall of the horizontal baffle near the other end of the vertical baffle by a fixing structure.

[0013] Furthermore, notches are provided at the positions corresponding to the horizontal and vertical baffles.

[0014] Furthermore, the other end of the vertical baffle extends into the notch.

[0015] Furthermore, the fixing structure includes an adhesive surface disposed on the inner wall of the adhesive strip and / or the transverse baffle near the other end of the vertical baffle.

[0016] Furthermore, the side of the adhesive strip facing the inside of the slot is formed with a friction damping structure.

[0017] Furthermore, the friction damping structure consists of friction protrusions formed on the side of the rubber strip facing the inside of the slot.

[0018] Furthermore, the friction damping structure is a friction stripe formed on the side of the rubber strip facing the inside of the slot.

[0019] Furthermore, the diameter of the clearance hole is D, and satisfies 16mm≤D≤30mm, and the central axis of the clearance hole is perpendicular to the plane where the placement surface is located.

[0020] Furthermore, the feeding tray is provided with a positioning structure for cooperating with the pick and place machine.

[0021] The technical solution provided by this utility model has the following advantages:

[0022] This utility model discloses a waffle box carrier, comprising a feeding tray, a baffle structure, and adhesive strips. The feeding tray has a flat placement surface. The baffle structure includes horizontal and vertical baffles integrally formed on the placement surface of the feeding tray. Each horizontal baffle extends in the horizontal direction and is arranged parallel to each other in the longitudinal direction. Several vertical baffles are provided between each pair of adjacent horizontal baffles, extending in the vertical direction and arranged parallel to each other in the horizontal direction. The horizontal and vertical baffles cooperate to divide the placement surface into several slots for placing waffle boxes. A clearance hole is provided on the feeding tray between one end of the vertical baffle and the horizontal baffle. Several adhesive strips, made of elastic material, are detachably installed on the inner wall of the horizontal baffle near the other end of the vertical baffle via a fixing structure.

[0023] This utility model's waffle cassette carrier adopts an integrated design and manufacturing method. In use, the adhesive strip is installed and fixed to the inner wall of the corresponding horizontal baffle, and the waffles are placed into the slots one by one. After all waffles are loaded, the operator installs the loading tray on the wafer loading platform. Because the outline of the loading tray is made according to the corresponding wafer size, it can be directly and seamlessly installed before proceeding to the next step. When it is necessary to unload the waffles from the slots, the operator can access the waffles through the clearance holes and then remove them one by one from the slots for subsequent processing.

[0024] This utility model's waffle cassette carrier is compatible with wafer loading platforms, eliminating the need for a separate dedicated waffle cassette loading platform or static support. Because the loading tray and baffle structure are designed and manufactured as a single unit, its manufacturing cost is significantly lower than the purchase cost of a waffle cassette loading platform or static support, thus significantly reducing the overall cost of production equipment and effectively solving the problems of high cost and low efficiency associated with traditional waffle cassette loading platforms. The combination of horizontal and vertical baffles forms a grid-like array of slots, resulting in a reasonable structure that is easy to manufacture. The adhesive strips enhance the fixing effect, preventing waffle cassette loosening, improving loading and unloading efficiency, and reducing the risk of waffle cassette displacement or falling due to vibration or tilting. The clearance holes facilitate the disassembly and assembly of waffle cassettes by operators or automated equipment, thereby improving loading and unloading efficiency and enhancing operational convenience and safety.

[0032] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] This embodiment provides a waffle box carrier, as shown in Figures 1 and 2, including a feeding tray 1, a baffle structure, and adhesive strips 4. The feeding tray 1 has a flat placement surface 10. The baffle structure includes horizontal baffles 2 and vertical baffles 3 integrally formed on the placement surface 10 of the feeding tray 1. Each of the horizontal baffles 2 extends in the horizontal direction and is arranged parallel to each other in the vertical direction. Several vertical baffles 3 are provided between two adjacent horizontal baffles 2. The vertical baffles 3 extend in the vertical direction and are arranged parallel to each other in the horizontal direction. The horizontal baffles 2 and the vertical baffles 3 cooperate to divide the placement surface 10 into several slots 101 for placing waffle boxes. A clearance hole 102 is provided on the feeding tray 1 between one end of the vertical baffle 3 and the horizontal baffle 2. Several adhesive strips 4 are made of elastic material and are detachably installed on the inner wall of the horizontal baffle 2 near the other end of the vertical baffle 3 by a fixing structure.

[0034] The waffle box carrier in this embodiment adopts an integrated design and manufacturing method. The material can be metal, such as 7075 aluminum alloy, which has the advantages of being lightweight, high-strength, and easy to process. In other embodiments, stainless steel, such as 304 stainless steel, can also be used, as it has excellent corrosion resistance and rigidity. The loading tray 1 can be designed as 8-inch or 12-inch as needed, and its outline can be referenced to the corresponding size (8-inch or 12-inch) wafer, thus ensuring good compatibility with 8-inch or 12-inch wafer loading platforms. Taking 12-inch wafers as an example, the loading tray 1 can be installed on a 12-inch wafer loading platform, with a thickness of approximately 1.2-1.8mm, for example, 1.5mm; the thickness of the horizontal baffle 2 is between 4.8mm-5.4mm, for example, 5.2mm; and the thickness of the vertical baffle 3 is between 1.8mm-2.4mm, for example, 2.2mm. After processing, mechanical leveling is used to ensure the flatness of the loading tray. The size and number of slots 101 can be set as needed. Taking a 12-inch loading tray as an example, when the waffle boxes to be supported are 2 inches in size, slots 101 can be set to 20 (4 rows, 5 per row) in a matrix distribution. The adhesive strip 4 is made of an elastic material, such as silicone or rubber. The length and width inside the slot 101 are slightly larger than the corresponding size of the waffle box to be placed, leaving a gap between the slot 101 and the waffle box. The adhesive strip 4 applies pressure to the waffle box by squeezing and filling the gap between the inner wall of the horizontal baffle 2 and the waffle box, thereby fixing the waffle box. The pressure of the adhesive strip 4 on the waffle box can be adjusted by adjusting the size of the adhesive strip 4 to prevent the waffle box from sliding or loosening. Taking a 12-inch loading tray as an example, in use, the adhesive strip 4 is installed and fixed on the inner wall of the corresponding horizontal baffle 2, and the waffle boxes 01 are placed into the slots 101 one by one; after all the waffle boxes 01 are loaded, the operator installs the loading tray 1 on the wafer loading platform. Since the outline of the feeding tray 1 is modeled after a 12-inch wafer, it can be installed seamlessly and the next operation can proceed. When it is necessary to unload the waffle box 01 from the slot 101, the operator can access the waffle box 01 through the clearance hole 102, and then remove the waffle boxes 01 one by one from the slot 101 for subsequent processing.

[0035] The waffle cassette carrier of this embodiment is compatible with wafer loading platforms, eliminating the need for a separate dedicated waffle cassette loading platform or static support. Because the loading tray and baffle structure are designed and manufactured as a single unit, its manufacturing cost is significantly lower than the purchase cost of a waffle cassette loading platform or static support, thereby significantly reducing the overall cost of production equipment and effectively solving the problems of high cost and low efficiency of traditional waffle cassette loading platforms. The combination of horizontal baffles 2 and vertical baffles 3 forms a grid-like array of slots 101, which is structurally sound and easy to manufacture. The adhesive strips enhance the fixing effect, preventing waffle cassette loosening, improving loading and unloading efficiency, and reducing the risk of waffle cassette displacement or falling due to vibration or tilting. The clearance holes 102 facilitate the disassembly and assembly of waffle cassettes by operators or automated equipment, thereby improving loading and unloading efficiency and enhancing operational convenience and safety.

[0036] In this embodiment of the waffle box carrier, a notch 20 is further provided at the position corresponding to the horizontal stop bar 2 and the vertical stop bar 3.

[0037] In this embodiment, the design of the notch 20 can avoid stress concentration between the horizontal baffle 2 and the vertical baffle 3, reduce the risk of deformation or breakage caused by material shrinkage or external force, and improve the overall durability of the baffle structure.

[0038] In this embodiment of the waffle box carrier, the other end of the vertical baffle 3 extends into the notch 20.

[0039] In this embodiment, the vertical baffle 3 extending into the notch 20 can increase the connection strength between the horizontal baffle 2 and the vertical baffle 3 to a certain extent, thereby improving the rigidity and reliability of the overall structure.

[0040] In this embodiment of the waffle box carrier, the fixing structure further includes an adhesive surface disposed on the inner wall of the adhesive strip 4 and / or the transverse baffle 2 near the other end of the vertical baffle 3.

[0041] In this embodiment, the adhesive strip 4 is adhered and fixed to the inner wall of the transverse baffle 2 via the adhesive surface. This method is simple in structure, easy to operate, and facilitates the replacement and maintenance of the adhesive strip 4. Simultaneously, this fixing method ensures a tight fit between the adhesive strip 4 and the waffle box, improving the cushioning effect.

[0042] In this embodiment of the waffle box carrier, the side of the adhesive strip 4 facing the inside of the slot 101 is further formed with a friction damping structure.

[0043] In this embodiment, the friction damping structure can increase the friction between the adhesive strip 4 and the waffle box, effectively preventing the waffle box from sliding in the slot 101. Even in a high vibration environment, it can maintain the stable position of the waffle box and improve the production yield.

[0044] In this embodiment of the waffle box carrier, the friction damping structure is further defined as friction protrusions formed on the side of the adhesive strip 4 facing the inside of the slot 101.

[0045] In this embodiment of the waffle box carrier, the friction damping structure is further described as friction stripes formed on the side of the adhesive strip 4 facing the inside of the slot 101.

[0046] In this embodiment, the friction bumps or friction stripes increase the coefficient of friction of the contact surface, thus more effectively securing the waffle box and preventing it from sliding or loosening within the slot. The implementation of friction bumps or friction stripes is simple, easy to manufacture, and inexpensive, while effectively providing the required frictional force, resulting in a compact structure that does not occupy excessive space.

[0047] In this embodiment of the waffle box carrier, the diameter of the clearance hole 102 is D, and satisfies 16mm≤D≤30mm, and the central axis of the clearance hole 102 is perpendicular to the plane where the placement surface 10 is located.

[0048] In this embodiment, the size of the clearance hole 102 allows operators to more easily access the waffle box, thereby improving loading and unloading efficiency and ease of operation.

[0049] In this embodiment of the waffle carrier, the feeding tray 1 is further provided with a positioning structure for cooperating with the pick and place machine.

[0050] In this embodiment, the feeding tray 1 may be provided with a positioning structure for cooperating with the pick and place machine, such as a first positioning groove 103 and a second positioning groove 104, which can ensure the accurate positioning and orientation of the feeding tray on the pick and place machine, improve the efficiency and accuracy of the automated production line, reduce manual intervention, and reduce production costs.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
