Description
Technical Field
[0001] This utility model relates to the field of electronic component tray technology, specifically a power electronic component storage device. Background Technology
[0002] Electronic component storage trays are a highly specialized and important type of electronic component storage device. They are specifically designed for the safe and orderly storage and transportation of components that are highly sensitive to static electricity and physical damage, especially components in various integrated circuits (ICs), chips, QFP, BGA, SSOP and other package forms. Its main feature is that it is made of antistatic material (such as black conductive PP or PS material) and has a large number of neatly arranged grooves on the surface (like a waffle grid). Each groove can hold a chip, thus effectively separating and protecting the components.
[0003] Existing electronic component storage trays have an open top, making components susceptible to vibration and ejection during transportation and handling. The traditional solution is to place a cover on top of the tray and gently press down on all the components in the tray's grooves, applying vertical pressure. However, the open cover needs to be placed somewhere, which takes up space, affects operational efficiency, and is inconvenient to use. Therefore, this paper proposes a power electronic component storage device. Utility Model Content

The rectangular protrusions are fixed to the top of the tray base plate, and the placement slots are integrally formed on the top of the tray base plate. Multiple placement slots are provided and distributed in a matrix on the inner side of the rectangular protrusions. The handles are symmetrically fixed to both ends of the top of the tray base plate. Anti-drop components are provided on both sides of the placement slots on the top of the tray base plate. The anti-drop components are used to limit the upper surface of the components placed inside the placement slots. The anti-drop component includes a limiting unit and a linkage unit; The limiting unit flips over above the placement slot to limit the position of the component; The linkage unit is used to realize the synchronous flipping operation of multiple sets of limit units.

A limiting piece is fixed at a position where the rotating rod is aligned with the middle of the placement slot. The rotating rod provides a flipping support for the limiting piece. When the limiting piece is flipped to a horizontal position, it covers the placement slot, thereby achieving the limiting operation of the component. The limiting piece is flipped to a vertical position away from the placement slot, thus releasing the limiting effect on the component.

A transmission groove is provided at the top of the tray base plate where it is aligned with the transmission gear, and a movable groove is formed at the bottom of the tray base plate where it is aligned with the transmission groove. The upper pressure plate is distributed above the transmission gear, and the transmission tooth plate is fixed to the bottom end of the upper pressure plate and meshes with the transmission gear. The up and down movement of the transmission tooth plate is used to provide power for the flipping of the limiting piece. A through-hole is provided at the bottom of the transmission groove, which is aligned with the transmission tooth plate. The through-hole is connected to the movable groove. The transmission tooth plate passes through the through-hole into the movable groove and is fixedly connected to the lower limit plate. The lower limit plate provides a limit for the upward movement of the transmission tooth plate and the upper pressure plate. The N-type springs are distributed inside the transmission groove, and the upper and lower ends of the N-type springs are tightly attached to the bottom of the upper pressure plate and the bottom of the inner wall of the transmission groove, respectively, to provide an upward thrust for the upper pressure plate.
[0008] As a further embodiment of this utility model: the two transmission gear plates distributed on the outermost two sides are single-sided gear plates and are symmetrically distributed with each other, while the other multiple transmission gear plates distributed in the middle are double-sided gear plates and mesh synchronously with the two transmission gears.
[0009] As a further embodiment of this utility model: an L-shaped pressure plate extending above the handle is fixed to one side of the upper pressure plate, and the vertical part of the L-shaped pressure plate is close to the top edge of the handle and is integrally formed with a triangular locking block.
[0010] As a further embodiment of this utility model: a number of supporting protrusions are fixed on the top of the tray base plate between two adjacent placement slots. The supporting protrusions do not contact the rotating rod, and the height of the supporting protrusions matches the height of the rectangular protruding edge.
[0011] As a further embodiment of this utility model: when the limiting piece is horizontal, it is attached to the upper surface of the tray substrate; when the limiting piece is vertical, the top horizontal height of the limiting piece is lower than the top horizontal height of the supporting protrusion.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-6In this embodiment of the utility model, a power electronic component storage device includes a tray assembly 1 composed of a tray base plate 101, a placement groove 102, a handle 103, and a rectangular protrusion 108. The rectangular protrusion 108 is fixed to the top of the tray base plate 101. The placement groove 102 is integrally formed on the top of the tray base plate 101. Multiple placement grooves 102 are provided and distributed in a matrix inside the rectangular protrusion 108. The handle 103 is symmetrically fixed to both ends of the top of the tray base plate 101. Anti-drop components 2 are provided on both sides of the placement groove 102 at the top of the tray base plate 101. The anti-drop components 2 are used to limit the upper surface of the components placed inside the placement groove 102. Anti-drop component 2 includes a limit unit and a linkage unit; The limiting unit flips above the placement slot 102 to limit the movement of the components; The linkage unit is used to realize the synchronous flipping operation of multiple sets of limit units; The limiting unit includes a rotating rod 201 and a limiting piece 202; Rotary rods 201 are symmetrically distributed in the placement groove 102 and pass through both sides of the rectangular protrusion 108. Rotary rods 201 are rotatably connected to the rectangular protrusion 108. A limiting piece 202 is fixed at a position where the rotating rod 201 is aligned with the middle of the placement slot 102. The rotating rod 201 provides a flipping support for the limiting piece 202. When the limiting piece 202 is flipped to a horizontal position, it covers the placement slot 102, thereby achieving the limiting operation of the component. The limiting piece 202 is flipped to a vertical position away from the placement slot 102, thus releasing the limiting effect on the component; The linkage unit includes a transmission gear 203, an upper pressure plate 204, a transmission toothed plate 205, a lower limit plate 206, and an N-type spring 207; The two sides of the rotating rod 201 extend to the outer sides of the rectangular protruding edge 108 and are fixedly connected to the transmission gear 203. A transmission groove 104 is provided at the top of the tray base plate 101 where it is aligned with the transmission gear 203, and a movable groove 105 is formed at the bottom of the tray base plate 101 where it is aligned with the transmission groove 104. The upper pressure plate 204 is located above the transmission gear 203. The transmission gear plate 205 is fixed to the bottom of the upper pressure plate 204 and meshes with the transmission gear 203. The up and down movement of the transmission gear plate 205 provides power for the flipping of the limiting piece 202. A through-hole 106 is provided at the bottom of the transmission groove 104, which is aligned with the transmission tooth plate 205. The through-hole 106 is connected to the movable groove 105. The transmission tooth plate 205 passes through the through-hole 106 and is fixedly connected to the lower limit plate 206 inside the movable groove 105. The lower limit plate 206 provides a limit for the upward movement of the transmission tooth plate 205 and the upper pressure plate 204. N-type spring pieces 207 are distributed inside the transmission groove 104, and the upper and lower ends of the N-type spring pieces 207 are tightly fitted with the bottom of the upper pressure plate 204 and the bottom of the inner wall of the transmission groove 104, respectively, to provide an upward thrust for the upper pressure plate 204. The two transmission gear plates 205 distributed on the outermost two sides are single-sided gear plates and are symmetrically distributed with each other. The other multiple transmission gear plates 205 distributed in the middle are double-sided gear plates and mesh synchronously with the two transmission gears 203.
[0017] In this embodiment, it should be noted that the inner wall size of the placement slot 102 matches the size of the electronic component to be placed. After the electronic component is placed inside the placement slot 102, the upper surface of the electronic component is flush with the upper surface of the tray substrate 101. The usage method for this tray assembly 1 is as follows: When it is necessary to place electronic components inside the placement slot 102, the upper pressure plate 204 is pushed downward, causing the upper pressure plate 204, the transmission gear plate 205, and the lower limit plate 206 to move downward as a whole (it should be noted that the movable groove 105 provides space for the lower limit plate 206 to move downward). The downward movement of the transmission gear plate 205 causes the transmission gear 203 to rotate, which in turn drives the rotating rod 201 to rotate. The rotating rod drives the limit piece 202 to flip, and the two limit pieces 202 symmetrically distributed on both sides of the placement slot 102 flip in opposite directions. Finally, all the limit pieces 202 flip from the horizontal state to the vertical state. At this time, the limit pieces 202 are away from the space above the placement slot 102, so that the electronic components can be placed inside the placement slot 102 smoothly. After all electronic components are placed, the downward pushing force on the upper pressure plate 204 is released. At this time, the upper pressure plate 204, the transmission gear plate 205, and the lower limit plate 206 are reset under the elastic force of the N-type spring 207 (it should be noted that during this process, the hand should be used to slowly release the upper pressure plate 204 to avoid the upper pressure plate 204 moving upward too quickly). Then, the limit piece 202 flips from the vertical state to the horizontal state, thereby limiting the upper surface of the electronic components. In this way, during the subsequent transfer process, the electronic components will not pop out due to external vibration, effectively improving the transportation stability of the electronic components.
[0018] Please refer to this carefully. Figure 1 , Figure 4 An L-shaped pressure plate 208 extending above the handle 103 is fixed to one side of the upper pressure plate 204. The vertical part of the L-shaped pressure plate 208 is close to the top side edge of the handle 103 and is integrally formed with a triangular locking block 209.
[0019] In this embodiment: by applying downward pressure to the L-shaped pressure plate 208, the upper pressure plate 204, the transmission gear plate 205, and the lower limit plate 206 can be moved downward as a whole. During this process, the triangular locking block 209 at the bottom of the vertical part of the L-shaped pressure plate 208 forms a squeezing with the handle 103. This squeezing force can deform the vertical part of the L-shaped pressure plate 208, thereby allowing the triangular locking block 209 to move smoothly downward to below the handle 103. At this time, the triangular locking block 209 loses the external squeezing force, and the vertical part of the L-shaped pressure plate 208 resets under its own elastic force, so that the straight edge of the triangular locking block 209 engages with the lower surface of the handle 103. In this way, a locking force is provided for the downward movement of the L-shaped pressure plate 208, the upper pressure plate 204, the transmission gear plate 205, and the lower limit plate 206, thereby achieving the locking of the vertical state of the limit piece 202. When unlocking is required, manually push the vertical part of the L-shaped pressure plate 208 outward to release the lock between the triangular block 209 and the handle 103. The operation is simple and convenient.
[0020] Please refer to this carefully. Figures 1-3 Several support protrusions 107 are fixed on the top of the tray base plate 101 between two adjacent placement slots 102. The support protrusions 107 do not contact the rotating rod 201. The height of the support protrusions 107 matches the height of the rectangular protrusion 108. When the limiting piece 202 is horizontal, it is attached to the upper surface of the tray substrate 101. When the limiting piece 202 is vertical, the top horizontal height of the limiting piece 202 is lower than the top horizontal height of the supporting protrusion 107.
[0021] In this embodiment: through the structural arrangement of the supporting protrusion 107 and the rectangular protrusion 108, when the upper and lower tray assemblies 1 are stacked, the limiting piece 202 on the bottom tray assembly 1 will not contact or interfere with the upper tray assembly 1. In addition, the horizontally positioned limiting piece 202 is attached to the tray substrate 101 and the upper surface of the electronic components, thereby limiting the electronic components while avoiding excessive pressure on the electronic components by the limiting piece 202.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
