Description

Technical Field

[0001] This invention relates to the field of semiconductor manufacturing technology, and more specifically to an adaptive positioning and locking carrier compatible with multi-size chip trays. Background Technology

[0002] In semiconductor manufacturing, the chip loading and transfer process plays a crucial role in ensuring production quality and efficiency. Chips must be precisely placed in anti-static trays to avoid potential damage caused by electrostatic discharge, and then secured using locking carriers to ensure stability during transfer. Traditional locking carriers generally use manual screw tightening or clip-on fixing methods. While these methods are simple in structure, they have significant limitations: Existing locking carriers are typically designed to be strictly matched to chip trays of a single size. When the production line needs to process chips of different specifications, a dedicated carrier must be used, resulting in a serious lack of equipment versatility. This not only prolongs production preparation time but also increases material management costs and operational complexity. During handling operations, the lack of synchronous locking between multiple carriers means that operators can only move individual carriers one by one, making safe stacking impossible and significantly reducing transfer efficiency. A more prominent problem is that when attempting to stack and move the carriers, relative displacement or tipping can easily occur due to insecure fixing, causing the chips inside the tray to detach from their original position or even break due to inertial impact, directly leading to a decrease in product yield and material waste. In addition, manually locking the chip trays relies on the operator's experience and is prone to failure due to uneven force or positioning deviation, further exacerbating the risks and hidden dangers during the transfer process. Summary of the Invention

[0003] The purpose of this application is to provide an adaptive positioning and locking carrier that is compatible with chip trays of multiple sizes, which solves the problems of insufficient versatility, low handling efficiency and easy chip damage of traditional locking carriers, and improves production efficiency and product yield.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adaptive positioning and locking carrier compatible with multi-size chip trays includes: The stage has a storage slot inside to accommodate chip trays, and a cover slot is opened on the inner wall of the stage. An adaptive clamping mechanism is disposed in the storage slot and located on the bottom side of the cover slot; The locking mechanism is set on the platform and is used for synchronous locking and handling between multiple platforms. The locking mechanism includes a locking cylinder, a deflector plate and a locking rod. The locking cylinder and the locking rod are respectively set on both sides of the platform. The locking rod and the locking cylinder are inserted into each other. The deflector plate is fixedly connected to the locking cylinder. The deflector plate has a cavity inside, and a locking block is slidably connected in the cavity to limit the locking rod. The closing mechanism is located inside the platform. The closing mechanism includes a cover roller and an adaptive pressing component. The outer side of the insert rod is provided with a toothed groove, and both ends of the cover roller are provided with gears that mesh with the toothed groove. The adaptive pressing component performs adaptive pressing when the insert rod is fully inserted into the locking cylinder.

[0005] Furthermore, the adaptive clamping mechanism includes a first guide rod, a first clamping plate, a first return spring, a second guide rod, a second clamping plate, and a second return spring; Guide grooves are provided on the inner walls of the platform. The first guide rod and the second guide rod are respectively set in different guide grooves. The first clamping plate and the second clamping plate are slidably connected to the first guide rod and the second guide rod, respectively. The first clamping plate is provided with a strip groove to accommodate the sliding of the second clamping plate. The first return spring is fixedly connected between the first clamping plate and the inner wall of the guide groove, and the second return spring is fixedly connected between the second clamping plate and the guide groove.

[0006] Furthermore, a third reset spring is provided between the inner wall of the dial plate cavity and the locking block, and a locking groove adapted to the locking block is opened on the outer wall of the insertion rod.

[0007] Furthermore, a pull rod is fixedly connected to the outer wall of the block, the pull rod passing through the lever plate and extending to the outside of the lever plate.

[0008] Furthermore, a stacked wheel is fixedly connected to the bottom end of the locking cylinder, and a belt is connected between the stacked wheels located on the same side of the platform, so that the locking cylinder is rotatably connected to the platform.

[0009] Furthermore, the adaptive pressure assembly includes a hollow slider and a roll cover; Two hollow sliders are provided, both of which are slidably connected to the cover plate groove. One end of the cover plate is fixedly connected to the hollow slider, and the other end is fixedly connected to the cover roller. An air bladder is embedded in the side of the cover plate near the storage tank. A miniature diaphragm pump is provided inside the hollow slider. One end of the air bladder is connected to the output end of the miniature diaphragm pump. A plug is provided on the outer wall of one hollow slider, and a socket adapted to the plug is opened on the outer wall of the other hollow slider to form a closed circuit with the miniature diaphragm pump.

[0010] Furthermore, the surfaces of the cover plate, hollow slider, and stage are all coated with an antistatic coating.

[0011] Furthermore, chip slots are provided on the outer wall of the stage to record information about the chips contained therein.

[0012] Furthermore, a fourth return spring is provided between the stacking wheel and the platform to automatically reset the locking cylinder without external interference.

[0013] The technical effects and advantages of this invention are as follows: This invention achieves adaptive positioning of multi-size chip trays through an adaptive clamping mechanism, completes synchronous locking and transportation of multiple carriers through a locking mechanism, and automatically responds to the insertion state of the insertion rod to perform a pressing operation. This solves the problems of insufficient versatility, low transportation efficiency and easy damage to chips in traditional locking carriers, thereby improving production efficiency and product yield.

[0014] This invention, through the design of a self-locking function between the locking cylinder and the insertion rod, enables the carrier to be stacked and transported synchronously. During stacking, the adaptive pressing component presses down on the edge of the chip tray from above, further improving the stability of the chip tray transport. Moreover, insertion immediately closes the container, forming a sealed protective space that prevents chip loss and meets the usage requirements. Attached Figure Description

[0017] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0018] This invention provides, for example Figures 1 to 8 As shown, an adaptive positioning and locking carrier compatible with multi-size chip trays includes: a platform 1, the platform 1 being designed to have a storage slot for accommodating chip trays to be transferred, the size of the storage slot being preset to accommodate chip trays within a specific range, and the inner wall of the platform 1 also having a cover plate slot 12, the cover plate slot 12 being a simple groove for guiding or supporting components of the subsequently installed closure mechanism 4.

[0019] The adaptive clamping mechanism 2 is set inside the storage slot and located on the bottom side of the cover slot 12. The main function of this mechanism is to automatically adjust its clamping position according to the size of the placed chip tray, thereby achieving stable positioning and clamping of trays of different sizes.

[0020] The locking mechanism 3 is mounted on the platform 1 to achieve synchronous locking and transport between multiple platforms 1. The mechanism includes a locking cylinder 31, a lever 32, and a rod 33. The locking cylinder 31 and the rod 33 are respectively located on both sides of the platform 1. The rod 33 can be manually pushed into the locking cylinder 31 to connect two adjacent platforms 1. The lever 32 is fixedly connected to the locking cylinder 31 and has a cavity inside. A locking block 321 is slidably connected in the cavity. The locking block 321 can be a simple elastic pin. When the rod 33 is fully inserted into the locking cylinder 31, the locking block 321 pops out under the action of the spring and enters the preset position on the rod 33, thereby limiting the rod 33 and preventing it from accidentally coming out.

[0021] The sealing mechanism 4 is set inside the platform 1. Its main function is to seal and press down the space above the chip tray after it is clamped and positioned, so as to further fix the tray and protect the chip. The mechanism includes a cover roller 41 and an adaptive pressing component 43. The outer side of the insertion rod 33 is provided with a toothed groove 331. The toothed groove 331 can be a series of evenly distributed toothed structures. The two ends of the cover roller 41 are provided with gears 42 that mesh with the toothed groove 331. When the insertion rod 33 is pushed in or pulled out, the meshing of the gear 42 with the toothed groove 331 drives the cover roller 41 to rotate, thereby driving a flexible cover to roll or unfold. The adaptive pressing component 43 can perform adaptive pressing when the insertion rod 33 is fully inserted into the locking cylinder 31.

[0022] In summary, the adaptive positioning and locking carrier compatible with multi-size chip trays provided in this embodiment effectively solves the problems of limited applicability and low handling efficiency of carriers in the prior art through the synergistic effect of its platform 1, adaptive clamping mechanism 2, locking mechanism 3, and closing mechanism 4. This carrier can adaptively clamp chip trays of different sizes, improving the compatibility of the equipment. At the same time, the locking mechanism 3 enables the synchronous locking and handling of multiple platforms 1, avoiding the risk of stacking and tipping, and significantly improving the efficiency and safety of chip transfer, ensuring the stability and protection of chips during the handling process.

[0023] Reference Figure 1 and Figure 2 The adaptive clamping mechanism 2 includes a first guide rod 21, a first clamping plate 22, a first return spring 23, a second guide rod 24, a second clamping plate 25, and a second return spring 26. Guide grooves 11 are provided on the inner walls of the platform 1. The first guide rod 21 and the second guide rod 24 are respectively disposed in different guide grooves 11. The first clamping plate 22 and the second clamping plate 25 are slidably connected to the first guide rod 21 and the second guide rod 24, respectively. A strip groove is provided on the first clamping plate 22 to accommodate the sliding of the second clamping plate 25. The first return spring 23 is fixedly connected between the first clamping plate 22 and the inner wall of the guide groove 11, and the second return spring 26 is fixedly connected between the second clamping plate 25 and the guide groove 11.

[0024] The adaptive clamping mechanism 2 is the core component for automatically positioning and clamping chip trays of different sizes. Its design aims to use a combination of mechanical structure and elastic elements to allow the clamping components to deform and adjust according to the actual size of the chip tray, thereby providing a stable and reliable clamping force. The first guide rod 21 and the second guide rod 24, as support components for linear motion, are typically made of high-strength, low-friction materials and require anti-static properties. Their surfaces are precision-machined to ensure the smoothness and stability of the sliding of the first clamping plate 22 and the second clamping plate 25. The first guide rod 21 and the second guide rod 24 provide precise movement trajectories in the guide grooves 11 on the inner wall of the stage 1, ensuring that the clamping components maintain the correct alignment during clamping. The first clamping plate 22 and the second clamping plate 25 are the components that directly contact the chip tray; their surfaces are typically flat and covered with anti-slip or anti-static materials to avoid damage to the chip tray and improve stability. Sufficient friction is provided, and they cooperate with the first guide rod 21 and the second guide rod 24 through a sliding connection, allowing them to move freely on the guide rods to adapt to changes in the size of the chip tray. The first return spring 23 and the second return spring 26 are elastic elements that provide clamping force, usually compression springs. One end of the spring is fixed to the first clamping plate 22 and the second clamping plate 25, and the other end is fixed to the inner wall of the guide groove 11 or the corresponding structure of the platform 1. When the chip tray is inserted, the spring is compressed, thereby generating a clamping force on the chip tray. The inner wall of the platform 1 is provided with guide grooves 11, and the first clamping plate 22 is provided with a strip groove to accommodate the sliding of the second clamping plate 25. This design is the key to achieving greater size compatibility. The strip groove allows the second clamping plate 25 to slide relative to the first clamping plate 22, thereby providing a wider adjustment range for the adaptive clamping mechanism 2 within the limited space of the carrier to adapt to chip trays with large size differences.

[0025] Reference Figure 3 and Figure 7 A third reset spring 322 is provided between the inner wall of the cavity of the dial plate 32 and the locking block 321, and a locking groove 332 adapted to the locking block 321 is provided on the outer wall of the insertion rod 33.

[0026] The function of the third return spring 322 is to provide a continuous preload or return force to the locking block 321, so that it can automatically maintain a preset position without external intervention. For example, when the insertion rod 33 is inserted or pulled out, it ensures that the locking block 321 can engage or disengage with the insertion rod 33 in a timely and accurate manner. The third return spring 322 can be in various forms such as a helical compression spring, torsion spring or leaf spring. Its elastic coefficient and stroke are designed according to the mechanical characteristics required for actual locking and unlocking. The slot 332 is a specially designed groove on the insertion rod 33. Its shape, size and position match the end of the locking block 321. When the insertion rod 33 is pushed into the locking cylinder 31 and reaches the predetermined position, the locking block 321 can slide precisely into the slot 332 under the action of the third return spring 322, thereby forming a stable mechanical lock. The slot 332 can be designed as a rectangular slot, a V-shaped slot or a slot with chamfered edges to ensure that the locking block 321 can enter smoothly and be reliably fixed.

[0027] Through the above technical solution, when the insertion rod 33 is fully inserted into the locking cylinder 31, the third return spring 322 can drive the locking block 321 to automatically and quickly lock into the slot 332 on the outer wall of the insertion rod 33. This design allows the insertion rod 33 to be reliably locked in the locking cylinder 31, effectively preventing accidental disengagement due to vibration or impact during the transport of the platform 1, and greatly enhancing the stability and safety of the connection between the platforms 1. At the same time, when unlocking is required, only an appropriate external force needs to be applied to overcome the elasticity of the third return spring 322, so that the locking block 321 can be disengaged from the slot 332, and the insertion rod 33 can be pulled out smoothly, realizing a convenient and controllable unlocking operation. This not only improves the reliability and ease of operation of the locking mechanism 3, but also ensures the overall stability of multiple platforms 1 during the synchronous locking and transport process.

[0028] Reference Figure 1 and Figure 7A pull rod 323 is fixedly connected to the outer wall of the locking block 321. The pull rod 323 passes through the lever plate 32 and extends to the outside of the lever plate 32. The pull rod 323 is a rod-shaped component used to apply external force to drive the locking block 321 to move. Its fixed connection with the locking block 321 ensures that the movement of the pull rod 323 can be directly and effectively transmitted to the locking block 321, thereby achieving precise control of the locking block 321. The pull rod 323 can be made of materials such as metal or high-strength engineering plastics. Its shape and size can be designed according to actual operating requirements. For example, it can be designed as a cylindrical rod with anti-slip texture to facilitate user gripping and force application. The pull rod 323 passes through... The through-plate 32 means that it passes through the body of the lever 32, with one part located inside the lever 32 and connected to the locking block 321, and the other part exposed outside the lever 32. Extending to the outside of the lever 32 clarifies that the outer part of the lever 323 is available for direct contact and force application by the operator. This design allows the operator to operate the locking block 321 directly without disassembly or the use of tools, greatly improving the ease of use and maintainability of the locking mechanism 3. The holes or slots on the lever 32 through which the lever 323 passes should be designed to be smooth enough to ensure that the lever 323 can slide smoothly, while preventing dust or foreign objects from entering and affecting the normal operation of the mechanism.

[0029] In the above embodiments, the locking cylinder 31 of the locking mechanism 3 is operated only by simple fixing or manual means. When multiple platforms 1 need to be locked or unlocked simultaneously, it may face problems such as inconvenience, low efficiency and difficulty in ensuring the consistency of the locking state between each platform 1.

[0030] In this regard, refer to Figure 3 and Figure 6 The bottom end of the locking cylinder 31 is fixedly connected to a stacked wheel 34. A belt is connected between the stacked wheels 34 located on the same side of the platform 1. The locking cylinder 31 is rotatably connected to the platform 1. A fourth reset spring 35 is provided between the stacked wheel 34 and the platform 1 for automatic reset of the locking cylinder 31 without external force interference.

[0031] Specifically, the locking cylinder 31 and the platform 1 are rotatably connected, which means that the locking cylinder 31 can rotate on the platform 1 with its own axis as the center, while its translation is restricted. This rotatable connection is usually achieved by setting corresponding bearing seats or holes on the platform 1 and allowing the shaft of the locking cylinder 31 to pass through the bearing (such as a sliding bearing or a rolling bearing), thereby ensuring that the locking cylinder 31 has good stability and low frictional resistance during rotation. The stacked wheel 34 is a wheel with one or more grooves, which is fixedly connected to the bottom end of the locking cylinder 31. This fixed connection ensures that any rotational movement of the locking cylinder 31 can be synchronously transmitted to the stacked wheel 34; conversely, when one of the stacked wheels 34 is driven to rotate by an external driving force, the belt transmits the rotational movement synchronously to all the stacked wheels 34 connected to it through its tension, thereby realizing the linkage of multiple locking cylinders 31 and realizing the synchronous release of multiple restriction points of the platform 1. The function of the pull rod 323 is to release the restriction at a single point, which is generally a backup method. When the synchronous unlocking step fails, it can be used to unlock one point at a time.

[0032] Reference Figure 8 The adaptive pressing component 43 includes a hollow slider 431 and a roll cover plate 432; The hollow slider 431 serves as the support and guide structure for the adaptive pressing component 43. Its internal cavity design accommodates the micro diaphragm pump. Two hollow sliders 431 are provided, each slidably connected to the cover groove 12 on the inner wall of the platform 1, ensuring smooth movement. The roll cover 432 serves as the main covering element, with one end fixedly connected to the hollow slider 431 and the other end fixedly connected to the roll cover roller 41. The roll cover 432 is typically made of a flexible and wear-resistant material, such as a polymer film or composite material, to allow for unfolding and rewinding under the drive of the roll cover roller 41, thereby covering or exposing the storage tank. The roll cover 432, hollow slider 431, and platform... All surfaces of 1 are coated with an antistatic coating, which can effectively dissipate the static charge generated by these components during contact and friction with the chip tray or chip. This significantly reduces the risk of static electricity accumulation and electrostatic discharge (ESD), thereby avoiding potential damage to sensitive chips caused by static electricity. Especially during the process of sealing, clamping and transporting chip trays, the roll cover 432 and hollow slider 431 have more frequent contact with the chip tray. The application of the antistatic coating can provide a safer storage and operation environment for the chip, ensuring that the performance and reliability of the chip are not affected by static electricity, thereby improving the overall protection capability and reliability of the chip of the carrier.

[0033] To achieve flexible downward pressure, an airbag 433 is embedded in the side of the roll cover 432 near the storage tank. The airbag 433 is a flexible cavity that can be inflated or deflated. Changes in its internal pressure can cause it to expand or contract, thereby providing a flexible downward pressure effect. The airbag 433 is embedded in the side of the roll cover 432 near the storage tank to ensure that it can directly act on the top of the chip tray when it expands. The airbag 433 is usually made of a material with good elasticity and sealing properties, such as silicone rubber, nitrile rubber or polyurethane elastomer, to adapt to repeated inflation and deflation without being easily damaged, and to withstand a certain internal pressure. Its flexible characteristics allow it to adaptively conform to the surface of chip trays of different heights and shapes, avoiding local stress concentration caused by hard contact.

[0034] To control the inflation and deflation of the airbag 433, a miniature diaphragm pump is installed inside the hollow slider 431. One end of the airbag 433 is connected to the output end of the miniature diaphragm pump. The miniature diaphragm pump is a small gas pump that generates a pressure difference through the reciprocating motion of the diaphragm to inflate or deflate the airbag 433. This pump is usually integrated inside the hollow slider 431. It is small in size, has low power consumption, and can provide precise air pressure control. Specifically, a miniature electric air pump of model VUY6002 can be used, which has a size of 60*40*32mm. With the help of a solenoid valve, the internal pressure of the airbag 433 can be precisely adjusted, thereby controlling the force and uniformity of the downward pressure.

[0035] To ensure the normal operation of the miniature diaphragm pump, a plug 434 is provided on the outer wall of one hollow slider 431, and a socket 435 adapted to the plug 434 is provided on the outer wall of the other hollow slider 431 to form a closed circuit with the miniature diaphragm pump. The plug 434 and the socket 435 are male and female connectors for electrical connection. When the two hollow sliders 431 slide in the cover plate groove 12 and approach or dock, the plug 434 will automatically insert into the socket 435, thereby establishing an electrical connection with the miniature diaphragm pump and forming a closed power supply and control circuit. This design ensures that the miniature diaphragm pump can automatically obtain power and control signals when it needs to work without additional manual connection, improving the automation level and ease of operation of the system. The specific power supply is buried in the bottom of the platform 1 (existing technology will not be described in detail), and the wires can be buried in the roll cover plate 432 and connected to the miniature diaphragm pump and the plug 434.

[0036] By introducing a hollow slider 431 and a roll cover 432 as the main structure of the adaptive pressing assembly 43, and cleverly embedding a connecting airbag 433 on the side of the roll cover 432 near the storage slot, combined with a miniature diaphragm pump set inside the hollow slider 431, precise inflation and deflation control of the airbag 433 is achieved. When the insertion rod 33 is fully inserted into the locking cylinder 31, the miniature diaphragm pump is activated through a closed loop formed by the plug 434 on the outer wall of one hollow slider 431 and the insertion hole 435 on the outer wall of another hollow slider 431, inflating the airbag 433, causing the airbag 433 to expand and apply a flexible and uniform downward pressure to the chip tray. When the predetermined pressure value is reached, the miniature diaphragm pump stops working. This pneumatic pressing method can adaptively conform to the surface of chip trays of different sizes and shapes, effectively avoiding local high-pressure damage that may be caused by traditional rigid pressure plates, while ensuring that the chip tray is firmly locked in the carrier, preventing shaking or displacement during transportation, thereby significantly improving the fixation reliability of the chip tray and the safety of the chip.

[0037] Reference Figure 1 and Figure 2 A chip slot 13 is provided on the outer wall of the stage 1 to record the information of the chip placed therein.

[0038] Chip slot 13 refers to a structure opened on the outer wall of the platform 1 for placing or fixing information carriers. The slot can be a groove, a transparent window, or an opening with a fixing mechanism. Its main function is to provide a physical location for inserting, pasting, or fixing information carriers related to the chip inside the carrier (e.g., paper labels, RFID cards, QR code labels, memory cards, etc.). In this way, the carrier itself carries the key information of its internal chip without the need for additional querying or manual verification.

[0039] The following example will provide a more detailed explanation of the above technical solution: In a semiconductor manufacturing plant, operator A needs to move a batch of chip trays of different sizes from the production line to the storage area. Traditional carriers can usually only match trays of specific sizes and are prone to tipping over during stacking and handling, resulting in chip damage. To solve these problems, the plant adopted the adaptive positioning and locking carrier provided by this technical solution.

[0040] First, operator A places a chip tray into the storage slot inside the platform 1 of the carrier. When the chip tray is placed, the first clamping plate 22 and the second clamping plate 25 slide inward along the first guide rod 21 and the second guide rod 24 respectively under the elastic action of the first return spring 23 and the second return spring 26, automatically clamping the side wall of the chip tray. Since the first clamping plate 22 has a strip groove to accommodate the sliding of the second clamping plate 25, the first clamping plate 22 and the second clamping plate 25 can slide relative to each other, thereby adapting to chip trays of different widths and achieving adaptive positioning and clamping of the tray. This design avoids the problem that traditional carriers need to be strictly matched with the size of the tray, improving the applicability of the carrier.

[0041] Next, operator A needs to stack multiple vehicles for synchronous transport. Operator A stacks one vehicle on top of another, aligning the insertion rod 33 of the upper vehicle with the locking cylinder 31 of the lower vehicle, and inserts and engages the two platforms 1. When the insertion rod 33 is fully inserted into the locking cylinder 31, the locking block 321 in the cavity of the lever 32 in the locking mechanism 3 automatically engages in the slot 332 on the outer wall of the insertion rod 33 under the elastic action of the third return spring 322, limiting the insertion rod 33 and preventing it from accidentally coming out during transport. If unlocking is required, simply move the lever 32 to rotate any one of the locking cylinders 31, and then move the stacking wheel 34. The linkage with the belt allows for simultaneous unlocking of the locking mechanisms 3 on multiple platforms 1, making unlocking convenient. The fourth reset spring 35 between the stacked wheel 34 and the platform 1 ensures that the locking cylinder 31 can automatically reset without external interference, improving the convenience and reliability of operation. Operator A can also pull the pull rod 323 fixedly connected to the outer wall of the locking block 321 to disengage the locking block 321 from the slot 332, and then pull out the insertion rod 33. The bottom end of the locking cylinder 31 is fixedly connected to the stacked wheel 34, and the stacked wheels 34 located on the same side of the platform 1 are connected by a belt. When the insertion rod 33 is inserted into the locking cylinder 31, another backup method is used for unlocking.

[0042] After the insertion rod 33 is fully inserted into the locking cylinder 31 and locked, the sealing mechanism 4 starts to work to protect the chips in the chip tray. When the insertion rod 33 is pushed, the toothed groove 331 drives the gear 42 to rotate, thereby driving the cover roller 41 to rotate and unfold the cover plate 432 from the cover roller 41 to cover the storage slot. When the cover plate 432 is fully unfolded and covers the chip tray, the airbag 433 embedded in the side of the cover plate 432 near the storage slot starts to work, and the inner side of the hollow slider 431... The miniature diaphragm pump starts and inflates the airbag 433 through a closed loop formed by the plug 434 on the outer wall of one hollow slider 431 and the socket 435 on the outer wall of another hollow slider 431. After inflation, the airbag 433 expands and adaptively presses down on the chip tray, firmly fixing it in the storage slot and preventing it from being thrown out or damaged during transportation. The cover plate 432, the hollow slider 431 and the surface of the stage 1 are all provided with an anti-static coating to further protect the chip from electrostatic damage.

[0043] In addition, a chip slot 13 is provided on the outer wall of the stage 1, where operator A can insert an information card to record information such as the batch and type of the chip, which is convenient for management and traceability.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
