Description

Technical Field

[0001] This utility model relates to the field of IGBT product storage and transportation, specifically to a handling pallet. Background Technology

[0002] IGBT products require storage and transportation during manufacturing, and pallets are used to accomplish this. A single pallet can hold multiple IGBT products, especially those from the same batch. However, in current technology, different IGBT products use different pallets, resulting in a large number of pallets and high mold costs. Furthermore, frequent pallet changes during turnover increase material turnaround time and reduce efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a handling pallet to solve the problems of high cost and low turnover efficiency in the storage and transportation of existing IGBT products.

[0004] To achieve the above objectives, this utility model provides a transport pallet, which is provided with a plurality of first storage structures and a plurality of second storage structures, wherein the first storage structures and the second storage structures correspond one-to-one, and the second storage structures are disposed within the first storage structures; both the first storage structures and the second storage structures are hollow; the first storage structures are used to place first type IGBT products, and the second storage structures are used to place second type IGBT products.

[0005] Optionally, the top of the transport pallet forms a receiving cavity, and the receiving cavity is provided with the first storage structure and the second storage structure. Both the first storage structure and the second storage structure extend upward from the bottom of the receiving cavity to a certain height. The outer side of the transport pallet is provided with a stepped surface, and the bottom of the transport pallet is provided with a locking groove.

[0006] Optionally, the stepped surface is defined by an inner ring and an outer ring, and each of the inner ring and the outer ring has a chamfer at one corner, with the chamfer position of the inner ring corresponding to the chamfer position of the outer ring.

[0007] Optionally, the first storage structure is provided with a first support surface for placing the first type of IGBT product, and the second storage structure is provided with a second support surface for placing the second type of IGBT product, wherein the height of the first support surface is greater than the height of the second support surface.

[0008] Optionally, the first storage structure includes four first support and limiting feet, which are spaced apart in a first direction and a second direction of the first storage structure. Each first support and limiting foot is provided with a first support part and a first limiting part. The top surface of all the first support parts constitutes the first support surface. The first limiting part is disposed on the outside of the first support part and is used to limit the first type of IGBT product.

[0009] Optionally, the second storage structure includes two second support limiting feet, which are spaced apart in a second direction of the second storage structure. Each second support limiting foot includes a second support portion extending along a first direction of the second storage structure. The two ends of the second support portion are provided with second limiting portions. The top surface of the second support portion constitutes the second support surface. The second limiting portions are used to limit the second type of IGBT product.

[0010] Optionally, the transport tray is further provided with a plurality of first foolproof structures and a plurality of second foolproof structures, wherein the first foolproof structures are used to restrict the installation direction of the first type of IGBT products, and the second foolproof structures are used to restrict the installation direction of the second type of IGBT products.

[0011] Optionally, both the first and second anti-mistake structures are anti-mistake columns with reinforcing ribs.

[0012] Optionally, the transport pallet is provided with an operating part, which includes at least one of a handle and a hand hole slot.

[0013] Optionally, the transport pallet is integrally injection molded.

[0014] As described above, this utility model provides a transport pallet with a first storage structure and a second storage structure of different sizes, capable of holding different IGBT products. This allows the same transport pallet to be compatible with various IGBT products, significantly reducing the number of transport pallets required, lowering mold costs, and improving turnover efficiency. Furthermore, because the second storage structure is located inside the first storage structure, forming an enclosure relationship, the overall size of the transport pallet is reduced, its weight and volume are lightened, facilitating its operation and use, while also allowing for the loading of more IGBT products, thus increasing the loading rate.

[0015] Furthermore, the system supports the stacking of multiple pallets during on-site handling, and the positioning and locking mechanism is achieved through the cooperation of the stepped surface and the locking groove, effectively preventing safety hazards such as pallet slippage and tipping, and significantly improving the reliability and safety of handling operations.

[0016] Furthermore, the aforementioned transport pallet is also equipped with a first error-proof structure and a second error-proof structure, which avoids incorrect installation direction through physical limit design, thereby reducing the operation error rate and improving loading efficiency.

Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] To make the objectives, advantages, and features of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the objectives of the embodiments of this utility model.

[0030] The purpose of this invention is to provide a transport tray for placing IGBT (Insulated Gate Bipolar Transistor) products. Furthermore, this transport tray can hold different IGBT products; specifically, it can hold two main categories of IGBT products, and further, it can hold four or five different types of IGBT products.

[0031] For example, in the prior art, there are two types of IGBT products: a first type (hereinafter referred to as HD1) and a second type (hereinafter referred to as HD4). The second type of IGBT product is smaller than the first type, mainly in length and width. The first type of IGBT product has two variations due to different terminal lengths; the second type of IGBT product has three variations, which may differ in the number of terminals, terminal positions, and / or cover structure, but their length and width are basically the same. Therefore, under certain circumstances, the handling pallet provided by this invention can simultaneously accommodate five types of IGBT products, significantly reducing the number of handling pallets required, significantly lowering production costs, and greatly improving turnover efficiency.

[0032] Of course, the handling pallet provided by this utility model is compatible with, but is not limited to, five IGBT products. The following description is in conjunction with the accompanying drawings.

[0033] like Figures 1 to 6 As shown, this utility model provides a transport tray 10 that can hold multiple IGBT products at once. The specific number of products can be placed is not limited, but generally, an even number of IGBT products can be placed at a time. In practice, for ease of operation, this transport tray 10 can hold a maximum of 4 or 6 IGBT products at a time. In this embodiment, the transport tray 10 holds 4 IGBT products at a time.

[0034] refer to Figures 1-2 As shown, the transport pallet 10 is provided with a plurality of first storage structures 11 and a plurality of second storage structures 12. Figure 2 Dashed boxes are used to highlight the details of the first storage structure 11 and the second storage structure 12 to make them easier to understand.

[0035] The second storage structure 12 is disposed within the first storage structure 11, that is, the first storage structure 11 contains the second storage structure 12, forming an inclusion relationship. The first storage structure 11 and the second storage structure 12 correspond one-to-one.

[0036] In this embodiment, the top of the transport tray 10 forms a receiving cavity 13, and the receiving cavity 13 is provided with a first storage structure 11 and a second storage structure 12. Both the first storage structure 11 and the second storage structure 12 extend upward from the bottom (i.e., the bottom surface) of the receiving cavity 13 to support the IGBT product. However, in other examples, the receiving cavity 13 may be omitted.

[0037] Furthermore, both the first storage structure 11 and the second storage structure 12 are hollow in shape, and their shape and size are configured to both support the corresponding IGBT product and limit the corresponding IGBT product, while also avoiding related structures / features on the IGBT product.

[0038] Specifically, both the first storage structure 11 and the second storage structure 12 support the corresponding IGBT products in the height direction of the transport pallet 10, so that the back of the IGBT products is kept at a certain distance from the bottom surface of the transport pallet 10 and does not contact it. At the same time, the corresponding IGBT products are limited in the length and width directions to prevent them from slipping.

[0039] Furthermore, the hollow shape of the first storage structure 11 and the second storage structure 12 allows them to avoid obstructing related structures / features on the back of the IGBT product. Additionally, the first storage structure 11 and the second storage structure 12 can also avoid obstructing the terminals on the IGBT product. Therefore, the shape and size of the first storage structure 11 and the second storage structure 12 can be adjusted according to the construction of the IGBT product.

[0040] More specifically, the first storage structure 11 is used to place the first type of IGBT product 20, and the second storage structure 12 is used to place the second type of IGBT product 30. The length and width of the first type of IGBT product 20 are both greater than those of the second type of IGBT product 30, specifically referring to the length and width of the main body of the IGBT product excluding the terminals.

[0041] Therefore, the handling pallet 10 provided in this application can hold different IGBT products, thus enabling the same handling pallet 10 to be compatible with different IGBT products, significantly reducing the number of handling pallets, lowering pallet mold costs, and improving turnover efficiency. Secondly, since the second storage structure 12 is located within the first storage structure 11, forming an inclusion relationship, the overall size of the handling pallet 10 is reduced, its weight and volume are lightened, facilitating its operation and use, while also allowing for the loading of more IGBT products, thus increasing the loading rate.

[0042] refer to Figure 7In some embodiments, the first type of IGBT product 20 includes a first product 21 and a second product 22. The first product 21 uses a small terminal A, and the second product 22 has a long terminal B in addition to the small terminal A. Both products 21 and 22 are placed on the first storage structure 11, so that the first storage structure 11 is compatible with the two products corresponding to the first type of IGBT product 20.

[0043] Continue to refer to Figure 7 In some embodiments, the second type of IGBT product 30 includes a first product 31 and a second product 32. These two products have different numbers of terminals and different cover plate structures, but their lengths and widths are basically the same.

[0044] refer to Figure 8 In some embodiments, the second type of IGBT product 30 also includes a third product 33. The third product 33 has a different cover structure than the first product 31, but has the same number of terminals and basically the same length and width.

[0045] It should be noted that the first type of IGBT product 20 may contain only one product or three or more products, and the second type of IGBT product 30 may contain one, two, three or more products. Regardless, the first type of IGBT product 20 is placed through the first storage structure 11, and the second type of IGBT product 30 is placed through the second storage structure 12. Furthermore, the second storage structure 12 will not interfere with the first type of IGBT product 20, and conversely, the first storage structure 11 will not interfere with the second type of IGBT product 30.

[0046] Key reference Figure 5 The first storage structure 11 has a first support surface 111 for placing a first type of IGBT product 20, and the second storage structure 12 has a second support surface 121 for placing a second type of IGBT product 30. In this embodiment, the height of the first support surface 111 is greater than the height of the second support surface 121, thereby accommodating IGBT products of different heights and preventing the second support surface 121 from interfering with the first type of IGBT product 20. However, in other examples, the height of the first support surface 111 may be less than or equal to the height of the second support surface 121.

[0047] The first storage structure 11 and the second storage structure 12 can support and limit the corresponding IGBT products in an optional manner.

[0048] refer to Figures 1 to 5In some preferred embodiments, the first storage structure 11 includes four first support and limiting feet 110, which are spaced apart in a first direction and a second direction. Each first support and limiting foot 110 has a first support portion 112 and a first limiting portion 113. The top surface of all the first support portions 112 forms a first support surface 111, and the first limiting portion 113 is disposed on the outside of the first support portion 112 to limit the first type of IGBT product 20. This first storage structure 11 is simple and easy to manufacture.

[0049] In this embodiment, the first direction of the first storage structure 11 is the length direction, and the second direction of the first storage structure 11 is the width direction. In other examples, the first direction of the first storage structure 11 is the width direction, and the second direction of the first storage structure 11 is the length direction.

[0050] Thus, the four first support limiting feet 110 are distributed at the four corners of the first type of IGBT product 20, providing support and limiting for the first type of IGBT product 20. The first limiting part 113 may have an L-shaped structure, capable of limiting the displacement of the first type of IGBT product 20 in both the first and second directions, and may be continuously or separately arranged.

[0051] Continue to refer to Figures 1-5 In some preferred embodiments, the second storage structure 12 includes two second support feet 120, which are spaced apart in a second direction of the second storage structure 12. Each second support foot 120 includes a second support portion 122 extending along a first direction of the second storage structure 12. Second limiting portions 123 are provided at both ends of the second support portion 122. The top surface of the second support portion 122 forms a second support surface 121. The second limiting portions 123 are used to limit the second type of IGBT product 30. This configuration results in a simpler structure and easier manufacturing. Simultaneously, the second support portions 122 strengthen the transport tray 10, preventing deformation under stress.

[0052] In this embodiment, the first direction of the second storage structure 12 is the length direction, and the second direction of the second storage structure 12 is the width direction. In other examples, the first direction of the second storage structure 12 is the width direction, and the second direction of the second storage structure 12 is the length direction.

[0053] Based on this, the second type of IGBT product 30 is supported by the second support portions 122 of the two second support limiting feet 120, while the second type of IGBT product 30 is limited by the second limiting portions 123 at both ends of the second support portions 122. Each second support limiting foot 120 is an integral design, that is, the second support portion 122 and the second limiting portion 123 are an integral or one-piece structure, resulting in good structural strength. Similarly, the second limiting portion 123 can limit the displacement of the second type of IGBT product 30 in both the first and second directions.

[0054] In this embodiment, the second limiting part 123 also serves as the first support part 112, and the first type of IGBT product 20 is placed on the top surface of the second limiting part 123. This structure is simpler and easier to process and manufacture.

[0055] refer to Figure 1 In some embodiments, the transport tray 10 is further provided with a plurality of first error-proof structures 14 and a plurality of second error-proof structures 15; the first error-proof structure 14 is used to restrict the installation direction of the first type of IGBT product 20 to prevent the first type of IGBT product 20 from being installed incorrectly; the second error-proof structure 15 is used to restrict the installation direction of the second type of IGBT product 30 to prevent the second type of IGBT product 30 from being installed incorrectly.

[0056] Specifically, in this embodiment, the receiving cavity 13 is provided with a first anti-misplacement structure 14 and a second anti-misplacement structure 15. Both the first anti-misplacement structure 14 and the second anti-misplacement structure 15 are located on the outside of the first storage structure 11 to avoid the terminals on the IGBT product. If the relative positions of the terminals and the anti-misplacement structure are accurate, the IGBT product can be successfully placed into the storage structure; otherwise, the installation will fail.

[0057] The first and second error-proof structures 14 and 15 have optional shapes and sizes. In this embodiment, both the first and second error-proof structures 14 and 15 are error-proof columns with reinforcing ribs. The error-proof columns can be circular, rectangular, elliptical, flat, or other various shapes, as long as they are easy to manufacture. In this embodiment, the error-proof column is a flat cone with reinforcing ribs on its two opposite planes. However, it is not limited to this in practice.

[0058] When correctly installed, the anti-misplacement posts corresponding to the first anti-misplacement structure 14 can be positioned between or to one side of the terminals of the first type of IGBT product 20, precisely avoiding obstruction of the terminals of the first type of IGBT product 20; similarly, the anti-misplacement posts corresponding to the second anti-misplacement structure 15 can be positioned between or to one side of the terminals of the second type of IGBT product 30, precisely avoiding obstruction of the terminals of the second type of IGBT product 30. However, it should be noted that this application does not limit the specific number and location of the anti-misplacement posts; in practice, they can be adjusted according to the terminal positions on the IGBT product.

[0059] refer to Figure 1 and Figure 2 In some embodiments, a chamfer 16 is provided at one corner of the transport pallet 10. This chamfer 16 is used to determine the installation direction of the transport pallet 10 and also serves as an alignment mark during production or testing on the production line. For example, a robotic arm can correctly grasp the transport pallet 10 based on this alignment mark, or the position of the IGBT product can be determined based on this alignment mark during testing.

[0060] Preferably, the outer side of the transport pallet 10 is provided with a stepped surface 17, and the bottom of the transport pallet 10 is provided with a locking groove 18 (see...). Figure 6 When multiple pallets 10 are stacked for use in on-site handling, the upper and lower pallets 10 can be positioned and locked by the cooperation of the stepped surface 17 and the locking groove 18, which effectively prevents the pallets 10 from slipping, tipping over and other safety hazards, and significantly improves the reliability and safety of handling operations.

[0061] Therefore, the stepped surface 17 is defined by an inner ring 171 and an outer ring 172. Based on this, both the inner ring 171 and the outer ring 172 have a chamfer 16 at one corner, and the position of the chamfer 16 of the inner ring 171 corresponds to the position of the chamfer 16 of the outer ring 172.

[0062] Preferably, the transport pallet 10 is provided with an operating part, which refers to the part of the transport pallet 10 that is operated manually.

[0063] In this embodiment, the operating part is a hand hole slot 19, which is provided on two opposite sides of the transport tray 10 for easy handling of the transport tray 10. The operating part may also be a handle. The handle and the hand hole slot 19 may be provided separately or simultaneously.

[0064] It should be further noted that the shape and size of the transport pallet 10 can be adjusted according to different needs and usage scenarios, and this application does not limit this. Typically, the transport pallet 10 is set as rectangular or square, and its length and width can be adjusted according to the dimensions of the loading track. For example, optionally, the transport pallet 10 has a length of 430mm and a width of 340mm.

[0065] Preferably, the transport pallet 10 is integrally injection molded.

[0066] In summary, this utility model provides a handling pallet 10 that is compatible with different IGBT products, significantly reduces the number of handling pallets, lowers mold opening costs, and improves turnover efficiency. Furthermore, the entire handling pallet 10 is small in size and lightweight, facilitating its operation and use. Utilizing the inclusion relationship between the first storage structure 11 and the second storage structure 12, it can hold a larger number of IGBT products, thus improving the loading rate.

[0067] It should be understood that the above embodiments specifically disclose the features of the preferred embodiments of this utility model, enabling those skilled in the art to better understand this utility model. Those skilled in the art should understand that, based on the disclosure of this application, appropriate modifications can be easily made to this utility model to achieve the same purpose and / or the same advantages as the disclosed embodiments.
