Description

Technical Field

[0001] This utility model belongs to the field of chip testing technology, and specifically relates to a chip box for chip testing. Background Technology

[0002] In the semiconductor industry's testing phase, chips typically require fixation and protection using specialized carriers before electrical performance testing and reliability assessment. Existing chip storage containers mostly only offer simple storage functions, and during handling or stacking, issues such as chip misalignment, container slippage, or insufficient sealing can easily occur. This can lead to chip damage, contamination, or electrostatic interference before testing, affecting the accuracy of the tests and the chip integrity rate.

[0003] Currently common chip storage boxes typically rely solely on the planar contact between their outer shells for stacking, lacking effective positioning and restraint structures. This makes them prone to tilting or loosening during stacking, resulting in insufficient stability. Furthermore, some storage structures lack specific design considerations for the chip placement slots, leaving chips at risk of movement within the slots and making them susceptible to damage from transport vibrations or handling. In addition, traditional snap-fit ​​or plug-in methods often require significant external force during disassembly, making operation inconvenient and prone to structural damage. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a chip box for chip testing, which can effectively fix the chip position during storage, achieve a stable connection and convenient disassembly when the boxes are stacked, and at the same time have good sealing performance to protect the chip from external contamination.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A chip test cassette includes a cassette body and a sealed top plate. The cassette body is stacked on top of each other. The surface of the cassette body is uniformly provided with material slots that are the same size as the chip. Limiting blocks are provided on the four edges of the material slots.

[0007] Fixing bolts are provided at the four corners of the upper surface of the box, and mating holes that are compatible with the fixing bolts are opened at the four corners of the lower surface of the box. An annular groove is opened on the surface of the fixing bolt near the box.

[0008] All the sliding grooves are opened at both ends of the bottom of the box body. Sliding rods are symmetrically slidably installed inside the sliding grooves. Limiting heads are provided at the opposite ends of the two sliding rods. The limiting heads are adapted to the width of the annular groove.

[0009] Furthermore, a fixing block is installed at the center of the inner side of the slide groove by screws, and fixing rods are provided on both sides of the fixing block, with both slide rods slidably mounted on the fixing rods.

[0010] Furthermore, all springs are fitted onto the surface of the fixed rod, and the springs are positioned between the fixed block and the sliding rod, with the springs applying an outward thrust to the sliding rod.

[0011] Furthermore, extension plates are provided on both sides of the box body, the extension plates are flush with the upper surface of the box body, and the thickness of the extension plates is less than that of the box body;

[0012] A notch is provided at the center of the outer side of the slide.

[0013] Furthermore, each of the two sliding rods is provided with a pressing angled rod at one end close to the other. The pressing angled rod passes through the notch groove, and the distance between the two pressing angled rods gradually decreases from the near end to the far end.

[0014] Furthermore, a control block is slidably mounted on the lower surface of the extension plate. The control block extends beyond the side of the extension plate, and an extrusion groove is formed on the lower surface of the control block. The ends of the two extrusion inclined rods are placed inside the extrusion groove, and the surface of the extrusion inclined rods is tangent to the edge of the opening side of the extrusion groove.

[0015] Furthermore, the lower surface of the control block is supported by two extrusion braces, the lower surface of the extension plate is provided with a track groove, and the upper surface of the control block is provided with a protruding bolt, which slides in the track groove.

[0016] Furthermore, the sealing top plate is slidably installed on the surface of the uppermost box, the sealing top plate is placed between the fixing bolts on both sides, and the rear end of the sealing top plate is the same width as the annular groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention solves the problems of insufficient internal stability and easy collision of chips in existing chip storage containers by opening a material groove on the surface of the box body and setting limiting blocks around the material groove. This ensures the integrity of the chip before testing and the accuracy of testing.

[0019] This invention features fixing bolts at the four corners of the box and matching docking holes on the lower surface. An annular groove is designed on the fixing bolts, which, together with the sliding rod, limiting head, and spring inside the sliding groove, form an automatic locking structure. This allows for a stable connection when multiple boxes are stacked, avoiding the loosening or tilting issues common in traditional chip storage boxes. This improves the overall stability after stacking and meets the safety requirements for chip testing and storage in batches.

[0020] This invention features a control block at the bottom of the box. Through the cooperation of the control block, the squeezing rod, and the sliding rod, the operator only needs to push the control block when the box needs to be separated. This causes the sliding rod to retract, releasing the locking relationship between the limiting head and the annular groove, thus achieving rapid separation between the boxes. This solves the problems of laborious disassembly and easy structural damage of existing snap-on storage boxes, improving the convenience and durability of use.

[0021] This invention features a sealed top plate on the surface of the uppermost box, which, through its limiting cooperation with the fixing bolts, achieves a stable installation. This effectively covers the material tray, preventing dust, particles, or static interference from contaminating and damaging the chips. This solves the problem of insufficient sealing in existing chip storage devices, ensuring that the chips are in a well-controlled environment before testing and improving the reliability of chip testing results.

Detailed Implementation

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] Example 1:

[0031] like Figures 1-5 As shown, a chip test cassette includes a cassette body 1 and a sealing top plate 2. The cassette body 1 is stacked vertically. The surface of the cassette body 1 is uniformly provided with material slots 11 that are the same size as the chips. Each of the four edges of the material slots 11 is provided with a limiting block 12. The limiting block 12 can limit and fix the chips during the chip placement process to prevent the chips from shaking during handling or testing, thereby solving the problem of insufficient stability of existing chip storage containers. The material slots 11 are opened in the recessed part of the surface of the cassette body 1 so that the limiting block 12 is lower than the upper surface of the cassette body 1, so that there is no interference when the sealing top plate 2 covers it, ensuring the tightness of the overall stack.

[0032] Fixing bolts 14 are provided at the four corners of the upper surface of the box body 1, and docking holes 15 that are adapted to the fixing bolts 14 are opened at the four corners of the lower surface of the box body 1. An annular groove 141 is opened at the end of the surface of the fixing bolt 14 near the box body 1. The end of the fixing bolt 14 is chamfered so that it can be smoothly inserted into the docking hole 15 during the stacking process. The annular groove 141 is used to engage with the limiting head 31 after the stacking is in place, so as to improve the stability of the stacking and solve the problem of easy loosening of existing chip storage boxes.

[0033] All the sliding grooves 16 are opened at both ends of the bottom of the box body 1. Sliding rods 3 are symmetrically slidably installed inside the sliding grooves 16. The ends of the two sliding rods 3 that are opposite to each other are provided with limiting heads 31. The limiting heads 31 are adapted to the width of the annular groove 141. The end of the limiting head 31 is provided with a chamfer. When the fixing bolt 14 is inserted, it can be compressed and displaced. The sliding rods 3 can slide smoothly in the sliding grooves 16 to ensure the smooth progress of the limiting action.

[0034] like Figure 4 and Figure 5 As shown, a fixing block 4 is installed in the center of the slide 16 by screws. Fixing rods 41 are provided on both sides of the fixing block 4. The two slide rods 3 are slidably installed on the fixing rods 41. The fixing rods 41 play a guiding role, enabling the slide rods 3 to move back and forth along a fixed trajectory. The fixing block 4 plays a role in bearing force and positioning, thereby ensuring the durability and reliability of the overall structure during use.

[0035] like Figure 4 and Figure 5 As shown, all springs 5 ​​are fitted on the surface of the fixing rod 41. The springs 5 ​​are placed between the fixing block 4 and the sliding rod 3. The springs 5 ​​apply an outward pushing force to the sliding rod 3, so that the limiting head 31 is in the outward extension position in its natural state, and can enter the docking hole 15 for snap-fit ​​positioning, thereby solving the problem of inconvenient assembly caused by the lack of an automatic reset structure in the existing device.

[0036] like Figure 4 and Figure 5 As shown, extension plates 13 are provided on both sides of the box body 1. The extension plates 13 are flush with the upper surface of the box body 1. The thickness of the extension plates 13 is less than that of the box body 1. The extension plates 13 can be used as handholds during handling, improving the convenience of operation. At the same time, the extension plates 13 ensure the stability of the sealed top plate 2 when it is covered, preventing slippage after stacking. A notch 17 is provided in the center of the outer side of the slide groove 16 to provide space for the movement of the compression diagonal bar 32.

[0037] like Figure 4 and Figure 5 As shown, each of the two sliding rods 3 has a pressing angled rod 32 at one end that is close to each other. The pressing angled rod 32 passes through the notch 17. The distance between the two pressing angled rods 32 gradually decreases from the near end to the far end. When the control block 6 is pushed, it can achieve linkage pressing, thereby driving the sliding rod 3 to retract inward, so that the limiting head 31 is separated from the annular groove 141, and the box body 1 is separated.

[0038] like Figure 4 and Figure 5 As shown, a control block 6 is slidably mounted on the lower surface of the extension plate 13. The control block 6 extends beyond the side of the extension plate 13. An extrusion groove 61 is formed on the lower surface of the control block 6. The ends of the two extrusion inclined rods 32 are placed inside the extrusion groove 61, and the surface of the extrusion inclined rods 32 is tangent to the edge of the opening side of the extrusion groove 61. When the control block 6 is pressed by external force, it slides along the lower surface of the extension plate 13, which can drive the extrusion inclined rods 32 to extrude the slide rod 3, thereby releasing the limiting structure and ensuring that the disassembly operation between the boxes 1 is simple, solving the problem of laborious operation of the traditional buckle structure.

[0039] like Figure 4 and Figure 5 As shown, the lower surface of the control block 6 is supported by two compression braces 32, the lower surface of the extension plate 13 is provided with a track groove 18, and the upper surface of the control block 6 is provided with a bolt 62. The bolt 62 slides in the track groove 18, and the track groove 18 provides a sliding trajectory for the bolt 62, which can effectively prevent the control block 6 from falling off and ensure the stable operation of the control mechanism.

[0040] like Figure 1 As shown, the sealing top plate 2 is slidably installed on the surface of the uppermost box 1. The sealing top plate 2 is placed between the two fixing bolts 14 on both sides. The rear end of the sealing top plate 2 is the same width as the annular groove 141. The sealing top plate 2 can effectively cover the uppermost box 1 by limiting the cooperation with the fixing bolts 14, preventing foreign objects from entering the material tank 11, thereby protecting the chip and solving the problem of insufficient sealing of existing chip storage devices.

[0041] Example 2:

[0042] See Figures 1-5A chip test cassette includes a cassette body 1, a sealed top plate 2, a material tray 11, a limiting block 12, a fixing bolt 14, a mating hole 15, an annular groove 141, a sliding groove 16, a sliding rod 3, a limiting head 31, a fixing block 4, a fixing rod 41, a spring 5, an extension plate 13, a notch 17, a pressing angled rod 32, a control block 6, a pressing groove 61, a track groove 18, and a protruding bolt 62, among other components. During operation, the chips to be tested are first placed one by one into the material tray 11 on the surface of the cassette body 1. The size of the material tray 11 is adapted to the shape of the chip. The limiting blocks 12 around the cassette limit the chip, ensuring stable fixation of the chip before testing and during handling, preventing chip displacement or damage due to vibration.

[0043] After the chips are placed, multiple boxes 1 are stacked. The fixing pins 14 of the lower box 1 are aligned with the docking holes 15 of the upper box 1. During insertion, the fixing pins 14 contact the chamfer of the limiting head 31 through their chamfered ends, causing the limiting head 31 to be compressed and push the slide rod 3 inward, compressing the spring 5 on the fixing rod 41 to generate stored force. When the fixing pins 14 are fully inserted into the docking holes 15 and aligned with the annular groove 141, the spring 5 releases its elasticity, pushing the slide rod 3 outward, so that the limiting head 31 is embedded in the annular groove 141, achieving a firm snap-fit. This process ensures that multiple boxes 1 can be tightly joined when stacked, solving the problem of loosening in traditional stacked storage devices.

[0044] After stacking, the sealing top plate 2 is installed on the surface of the uppermost housing 1. The sealing top plate 2 is positioned between the two fixing bolts 14 and is stably fixed by matching the width of the annular groove 141, thereby covering the material slot 11 of the uppermost housing 1. The sealing top plate 2 prevents external dust, particles, or static electricity from contaminating and interfering with the chip, ensuring the cleanliness and safety of the chip before the testing process, and solving the problem of insufficient sealing performance of existing chip storage devices.

[0045] During separation, pressing the control block 6 below the extension plate 13 causes the control block 6 to slide along the track groove 18. The protruding bolt 62 on the control block 6 guides it within the track groove 18, ensuring that the control block 6 will not fall off. During the sliding process, the pressing groove 61 on the lower surface of the control block 6 drives the pressing inclined rods 32 to move closer together. The pressing inclined rods 32 push the sliding rod 3 to move inward synchronously, causing the limiting head 31 to exit from the annular groove 141. The fixing bolt 14 disengages from the docking hole 15, and the multiple boxes 1 can be easily separated. This process does not require the use of external tools and is convenient and efficient.

[0046] In summary, this embodiment ensures the stability of chip placement through the material tray 11 and the limiting block 12, ensures the stability of stacked connection through the snap-fit ​​structure of the fixing bolt 14, the docking hole 15, the limiting head 31 and the annular groove 141, achieves automatic limiting through the reset action of the spring 5 and the slide bar 3, achieves quick disassembly through the cooperation of the control block 6, the extrusion inclined rod 32 and the extrusion groove 61, and improves the overall protection capability through the sealing top plate 2. Thus, it solves the shortcomings of existing chip storage and testing auxiliary devices in terms of chip fixing, stacking stability and sealing.

[0047] The working principle of this utility model is as follows: The chips to be tested are placed one by one inside the material tank 11. The limiting block 12 can further improve the stability of the chips. The material tank 11 is opened in the concave surface of the box body 1 so that the limiting block 12 is lower than the upper surface of the box body 1. The box body 1 is moved by holding the extension plate 13 so that multiple boxes 1 are stacked one by one. The fixing bolt 14 of the lower layer can enter the docking hole 15 of the upper layer, thereby achieving stability after stacking. Then, the sealing top plate 2 is installed on the surface of the uppermost box body 1 and limited by the fixing bolt 14 so that the sealing top plate 2 can cover the uppermost box body 1 and fold foreign objects to effectively protect the chips.

[0048] Under normal conditions, due to the pushing force of the spring 5 on the slide rod 3, the two slide rods 3 are separated from each other and enter the docking hole 15. At the same time, the control block 6 can be squeezed out by the squeezing bar 32, so that the control block 6 extends beyond the side of the extension plate 13. The bottom of the control block 6 is supported by the squeezing bar 32. Meanwhile, the protruding bolt 62 can only slide inside the track groove 18 to restrict the control block 6 as a whole and prevent it from falling. When stacked, the end of the fixing bolt 14 is chamfered and the end of the limiting head 31 is also chamfered. Therefore, when the fixing bolt 14 enters the docking hole 15, it can squeeze the limiting head 31, so that the slide rods 3 are close to each other and squeeze the spring 5 to store force. After the stacked placement is in place, the fixing bolt 14 is completely inserted into the docking hole 15. At this time, the elastic force of the spring 5 can make the limiting head 31 enter into the annular groove 141 to limit the annular groove 141, so as to make the multiple stacked boxes 1 stably connected.

[0049] Conversely, during separation, the control block 6 can be pressed to slide inward, and then the edge of the extrusion groove 61 will press the extrusion rod 32, so that the centers of the two extrusion rods 32 are close together, so that the limiting head 31 disengages from the annular groove 141, thereby realizing the separation between the boxes 1. It should be noted that the bottom of the slide rod 3 and the control block 6 should not be lower than the lower surface of the box 1, so that the two adjacent boxes 1 can be tightly attached to each other during the stacking and sewing, so as to ensure stability and protect the chip.

[0050] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
