Description

Technical Field

[0001] The present invention relates to the technical field of electronic product processing, and relates to a packaging structure for encapsulating products. Background Art

[0002] The packaging of electronic products is mainly to prevent electrostatic breakdown, pin extrusion deformation, surface damage, contamination, and facilitate use during the processes of screening and assessment, transportation, storage, and installation on the whole machine board after encapsulation.

[0003] Currently, the two common practices for packaging CSOP encapsulated products in the industry are as follows:

[0004] (1) According to the shape size and lead pitch of the product, customize a dedicated packaging tray;

[0005] (2) Use the method of cutting holes in the sponge. By cutting out different shape sizes on the sponge, the packaging is achieved by fixing the shape of the product.

[0006] These two packaging methods have the following problems in actual use:

[0007] (1) Different from plastic encapsulated products in mass production, ceramic encapsulated products are characterized by multiple varieties and small batches. Their product varieties and sizes are diverse, and the number of products encapsulated at one time is small. If dedicated packaging is customized for each type of encapsulation and each shape size of the product, the processing cycle is long and the cost is high. If there are urgent products to be processed and there is no suitable packaging, it will inevitably affect the progress of customers at this time. The high mold opening fee for customizing the tray also increases the production cost. At the same time, a large number of various packaging trays will also occupy a large amount of space in the material warehouse, increasing the management cost;

[0008] (2) For the packaging method of cutting holes in the sponge, although its flexibility has been greatly improved compared with custom trays and there is no need to customize dedicated packaging for different types of components, due to its packaging method of cutting holes and embedding, the protection of the packaging is not as good as that of custom trays, and the pins of the product are very likely to be deformed during the processes of transfer and transportation, etc., which has a great impact on customer applications.

[0009] Therefore, a practical, flexible, and highly operable packaging structure for encapsulating products is needed. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to provide a packaging structure. By using a fixing clip to clamp on the edges of multiple stacked packaging trays for clamping and fixing, it can package products with different outer shapes and sizes, shorten the processing cycle of packaging materials, improve production efficiency, and reduce manufacturing costs at the same time. The placement board is matched with the limit groove, which can ensure the stacking accuracy of multiple packaging trays. The multiple ribs provided on the groove not only meet the bearing strength of the packaging tray, save the material usage, reduce the manufacturing cost, but also can fix the pins of different types of CSOP packaged products, and to a certain extent, be compatible with CSOP packaged products with different sizes and different lead spacings, with a wide range of applications.

[0011] To solve the above technical problems, the technical solution adopted by the present invention to solve its technical problems is:

[0012] A packaging structure for packaged products, including a fixing clip and multiple packaging trays. The fixing clip is clamped on the edges of multiple stacked packaging trays for clamping and fixing.

[0013] A limit groove is provided on the bottom surface of the packaging tray, and a placement board is provided on the top surface of the tray. Multiple packaging trays are stacked by connecting the placement board of the packaging tray at the bottom with the limit groove of the packaging tray at the upper part.

[0014] A placement groove for placing packaged products is provided on the placement board. Multiple partitions are provided on the placement groove. The multiple partitions evenly divide the placement groove into multiple grooves for placing single packaged products. Multiple ribs are provided on the bottom surface of the groove, and the ribs are clamped between adjacent pins of the packaged product.

[0015] Further, multiple bumps are evenly provided on the limit groove, and the bumps are arranged in one-to-one correspondence with the grooves. When multiple packaging trays are stacked, the bumps on the upper packaging tray press the packaged products on the lower packaging tray into the grooves.

[0016] Further, a support channel is formed between adjacent bumps, and the support channel is arranged opposite to the partition. When multiple packaging trays are stacked, the partition passes through the support channel and abuts against the bottom surface of the limit groove.

[0017] Further, the fixing clip includes a fixing plate. Vertical plates are perpendicularly provided on both sides of the fixing plate. A pressing plate is provided at the free end of the vertical plate, and the pressing plate is perpendicularly arranged with the vertical plate. When the fixing clip clamps multiple stacked packaging trays, the fixing plate abuts against the bottom surface of the packaging tray, the vertical plate abuts against the side surface of the packaging tray, and the pressing plate presses on the edge of the topmost packaging tray.

[0018] Further, positioning plates are provided on both sides of the fixing plate. An elastic plate is provided at the free end of the positioning plate. The middle part of the elastic plate bulges upward to form an Ω-shaped structure. When the fixing clip clamps a plurality of packaging trays, the elastic plate is clamped on the support channel of the lowermost packaging tray.

[0019] Further, a guiding arc surface is provided at the edge of the placing plate. A supporting arc surface matching the guiding arc surface is provided on the side wall of the limiting groove. The guiding inclined surface abuts against the supporting arc surface.

[0020] Further, the width of the rib is slightly larger than the distance between two pins of the encapsulated product, so that the rib is clamped between adjacent pins of the encapsulated product.

[0021] Further, the rib is of a hollow structure, and the width of the rib is less than or equal to the distance between two pins of the encapsulated product. When the bump on the upper packaging tray presses the encapsulated product on the lower packaging tray during the stacking process of a plurality of packaging trays, the bump on the upper packaging tray drives the groove thereon to bulge upward, so that the rib deforms to clamp the pins of the encapsulated product.

[0022] Further, the rib includes a top surface and two side surfaces. The side surfaces are vertically arranged on the bottom surface of the groove. The two ends of the top surface are connected to the two side surfaces. A hollow cavity is formed between the top surface and the side surfaces. The top surface is made of an elastic material.

[0023] Advantages of the present invention:

[0024] The present invention clamps and fixes a plurality of stacked packaging trays by clamping a fixing clip on the edges of the stacked packaging trays, can package products with different outer shapes and sizes, shortens the processing cycle of packaging materials, improves production efficiency, and reduces manufacturing costs at the same time; the placing plate and the limiting groove are arranged in a matching manner, which can ensure the stacking accuracy of a plurality of packaging trays; the plurality of ribs arranged on the groove not only meet the bearing strength of the packaging tray, save the material consumption, reduce the manufacturing cost, but also can fix the pins of different types of CSOP encapsulated products, and are compatible with CSOP encapsulated products with different sizes and different lead pitches to a certain extent, and have a wide application range.

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the specific embodiments cited are not intended to limit the present invention.

[0034] Refer to Figures 1-7 As shown, a packaging structure for an encapsulated product includes a fixed clamp 3 and a plurality of packaging trays 1. The fixed clamp 3 is clamped on the edges of the stacked plurality of packaging trays 1 to clamp and fix them;

[0035] A limiting groove 4 is provided on the bottom surface of the packaging tray 1, and a placing board 11 is provided on the top surface 23 of the tray. The placing board 11 of the packaging tray 1 at the bottom is connected to the limiting groove 4 of the packaging tray 1 at the upper part to realize the stacking of the plurality of packaging trays 1;

[0036] A placing groove for placing the encapsulated product 5 is formed on the placing board 11. A plurality of partition boards 12 are provided on the placing groove. The plurality of partition boards 12 evenly divide the placing groove into a plurality of grooves 13 for placing a single encapsulated product 5. A plurality of ribs 2 are provided on the bottom surface of the groove 13, and the ribs 2 are clamped between adjacent pins of the encapsulated product 5.

[0037] The present invention clamps and fixes multiple stacked packaging trays 1 by means of a fixing clip 3 clamped on the edges of the stacked trays, enabling packaging of products with different external dimensions, shortening the processing cycle of packaging materials, improving production efficiency, and reducing manufacturing costs at the same time; the placement board 11 is arranged to match the limit groove 4, which can ensure the stacking accuracy of multiple packaging trays 1; the multiple ribs 2 provided on the groove 13 not only meet the load-bearing strength of the packaging tray 1, save material usage, and reduce manufacturing costs, but also can fix the pins of different types of CSOP package products 5, and to a certain extent, are compatible with CSOP package products 5 with different sizes and different lead pitches, with a wide range of applications.

[0038] The packaging tray 1, the fixing frame, and the bump 41 of the rib 2 of the present invention are all processed from ABS anti-static materials, which have good impact resistance, heat resistance, low temperature resistance, and anti-static performance, and can be reused.

[0039] A plurality of bumps 41 are uniformly arranged on the limit groove 4, and the bumps 41 are arranged in one-to-one correspondence with the grooves 13. When multiple packaging trays 1 are stacked, the encapsulated product 5 of the lower packaging tray 1 is pressed tightly in the groove 13 by the bumps 41 on the upper packaging tray 1.

[0040] Specifically, when multiple packaging trays 1 are stacked, the encapsulated product 5 of the lower packaging tray 1 is pressed tightly in the groove 13 by the bumps 41 on the upper packaging tray 1. Bumps 41 with different thicknesses and sizes are made at the bottom of the tray, so that when two packaging trays 1 are stacked, the bumps 41 at the bottom of the upper tray can press the upper surface of the lower encapsulated product 5, enabling fixation in the Z-plane direction and preventing the pins from deforming due to the shaking of the encapsulated product 5.

[0041] A support channel 42 is formed between adjacent bumps 41, and the support channel 42 is arranged opposite to the partition 12. When multiple packaging trays 1 are stacked, the partition 12 passes through the support channel 42 and abuts against the bottom surface of the limit groove 4.

[0042] The fixing clip 3 includes a fixing plate 33, vertical plates 31 are vertically arranged on both sides of the fixing plate 33, a pressing plate 32 is arranged at the free end of the vertical plates 31, and the pressing plate 32 is perpendicular to the vertical plates 31. When the fixing clip 3 clamps multiple stacked packaging trays 1, the fixing plate 33 abuts against the bottom surface of the packaging tray 1, the vertical plates 31 abut against the side surface 22 of the packaging tray 1, and the pressing plate 32 presses on the edge of the topmost packaging tray 1.

[0043] Positioning plates 34 are arranged on both sides of the fixed plate 33. Elastic plates 35 are arranged at the free ends of the positioning plates 34. The middle part of the elastic plate bulges upward to form an Ω-shaped structure 36. When the fixing clip 3 clamps a plurality of packaging trays 1, the elastic plate is clamped on the support channel 42 of the lowermost packaging tray 1.

[0044] Specifically, the middle part of the elastic plate bulges upward to form an Ω-shaped structure 36. When the fixing clip 3 fixes the stacked packaging trays 1, under the reaction force of the elastic plate, the pressing plate 32 is pressed on the edge of the uppermost packaging tray 1, and the bumps 41 on each packaging tray 1 are pressed tightly on the encapsulated product 5, so as to better fix the encapsulated product 5 in the Z-plane direction.

[0045] A guiding arc surface 44 is arranged at the edge of the placing plate 11. A supporting arc surface 43 matching the guiding arc surface 44 is arranged on the side wall of the limiting groove 4. The guiding inclined surface abuts against the supporting arc surface 43.

[0046] Specifically, the guiding inclined surface abuts against the supporting arc surface 43. Through the limiting grooves 4 around the bottom of the packaging tray 1 and the placing plate 11, two packaging trays 1 can be stacked and positioned together to ensure the stacking accuracy.

[0047] Refer to Figures 6-7 As shown, the width of the rib 2 is slightly larger than the distance between two pins of the encapsulated product 5, so that the rib 2 is clamped between adjacent pins of the encapsulated product 5.

[0048] Specifically, the rib 2 is clamped between adjacent pins of the encapsulated product 5 to fix the pins between the encapsulated products 5, so that they do not move in the XY-plane direction, ensuring the stability during transportation and avoiding deformation of the pins during processes such as transfer and transportation, which has a great impact on customer applications.

[0049] The rib 2 is a hollow structure 21. The width of the rib 2 is less than or equal to the distance between two pins of the encapsulated product 5. When the bumps 41 on the upper packaging tray 1 press the encapsulated product 5 on the lower packaging tray 1 during the stacking process of a plurality of packaging trays 1, the bumps 41 on the upper packaging tray 1 drive the grooves 13 thereon to bulge upward, causing the rib 2 to deform to clamp the pins of the encapsulated product 5.

[0050] Specifically, the distance between the top of the rib 2 and the bump 41 is slightly larger than the thickness of the encapsulated product 5, so that when stacking the packaging trays 1, under the reaction force of the encapsulated product 5, the groove 13 can be bulged upward, causing the rib 2 to deform to clamp the pins of the encapsulated product 5.

[0051] A cavity structure that is interconnected can be provided between the convex ribs 2 and the bumps 41. When the encapsulated product 5 presses on the bumps 41 (the fixed clamp 3 stacks and fixes them), the convex ribs 2 are made of an elastic material (such as a thin-walled structure like a balloon). The convex ribs 2 undergo a slight expansion deformation, so as to clamp the pins of the encapsulated product 5.

[0052] Referring to Figure 7 As shown, the convex rib 2 includes a top surface 23 and two side surfaces 22. The side surfaces 22 are vertically arranged on the bottom surface of the groove 13. Both ends of the top surface 23 are connected to the two side surfaces 22. A hollow cavity is formed between the top surface 23 and the side surfaces 22. The top surface 23 is made of an elastic material.

[0053] Specifically, the top surface 23 is an elastic structure, and the stiffness of the side surfaces 22 is much greater than that of the top surface 23. When the packaging trays 1 are stacked, the bumps 41 on the upper packaging tray 1 drive the grooves 13 thereon to bulge upward, so that the free ends of the two side surfaces 22 can be relatively separated, causing the top of the convex rib 2 to expand and increasing the distance between the two side surfaces 22, thereby clamping the two pins 51 so that the pins 51 cannot break away from the pressure strip.

[0054] Specifically, the top surface 23 may not be provided on the convex rib 2 of the present invention, and the encapsulated product 5 is directly placed on the two side surfaces 22. The two side surfaces 22 and the groove 13 are an integrally formed structure. When the bump 41 jacks up the groove 13, the free ends of the two side surfaces 22 can be relatively separated to form a trapezoidal structure, increasing the distance between the two side surfaces 22 and clamping the two pins 51.

[0055] Specifically, when the convex rib 2 is a hollow structure 21, the height of the convex rib 2 in the middle of the groove 13 is slightly less than the height of the convex rib 2 on the outside, so that when the groove 13 is under the action of the bump 41, there is a margin for upward bulging, ensuring the support for the encapsulated product 5 and preventing it from being damaged during the packaging process.

[0056] During the use process

[0057] In the present invention, grooves 13 corresponding to the size of the encapsulated product 5 are uniformly made on the placement plate 11 of the packaging tray 1. The trimmed CSOP encapsulated products 5 are sequentially placed in the centers of the grooves 13 of the packaging tray 1, and a plurality of equally spaced convex ribs 2 are provided in the grooves 13 to fix the pins of the encapsulated product 5, so that the convex ribs 2 in the grooves 13 can clamp between two adjacent pins of the encapsulated product 5, ensuring that the encapsulated product 5 does not move in the XY plane direction;

[0058] Then, another same packaging tray 1 is taken and placed on the packaging tray 1 already loaded with products. The placement plate 11 of the bottom packaging tray 1 and the limit grooves 4 of the upper packaging tray 1 enable the two packaging trays 1 to be stacked and fixed together;

[0059] Meanwhile, bumps 41 matching the encapsulated products 5 (with different thicknesses and sizes) are made at the bottom of the limit groove 4. When multiple packaging trays 1 are stacked, the bumps 41 at the bottom of the upper packaging tray 1 press against the surface of the encapsulated products 5 in the lower packaging tray 1, enabling fixation in the Z-plane direction. Finally, fixing clips 3 are used to clamp and fix between the stacked trays. The elastic plate is arranged on the support channel 42 of the lowermost packaging tray 1 to ensure that the products will not shake during transportation, causing lead deformation.

[0060] The above-described embodiments are merely preferred embodiments cited to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are within the protection scope of the present invention. The protection scope of the present invention is subject to the claims.
