Description

Technical Field

[0001] This application relates to the field of lifting equipment technology, specifically to a high-altitude cargo rescue lifting device. Background Technology

[0002] In semiconductor cleanrooms, high-altitude rescue operations in case of malfunctions in automated material handling systems generally rely on A-frame ladders. Workers must climb to a height of about 3 meters to manually pick up and place standard containers storing wafers, which poses a risk of falling from height and damaging the wafers. In addition, at least several people are required to work together, resulting in high labor costs and weak protection.

[0003] Although existing technologies include hydraulic or electric guardrail lifting devices, they are difficult to apply in cleanrooms due to problems such as hydraulic oil leakage polluting the clean environment, unreliable battery power supply, and frequent lifting causing wafers to stay in non-clean environments for too long. This results in low safety, poor efficiency, and insufficient reliability of existing rescue methods. Utility Model Content

[0004] This application provides a high-altitude cargo lifting device that enables the separation of personnel and cargo transportation, improves the personnel safety risks and cargo transfer risks existing in traditional cargo rescue methods, and ensures the safety of personnel and cargo.

[0005] In a first aspect, an aerial cargo lifting device is provided according to an embodiment of this application. Divided into a pedestrian work area and a cargo work area, the aerial cargo lifting device further includes: a carrying mechanism; a stair mechanism located on one side of the carrying mechanism and in the pedestrian work area, the stair mechanism including a climbing ladder and a work platform, the work platform being at a preset height distance from the carrying mechanism along a first direction, the climbing ladder overlapping the work platform and the carrying mechanism, and the climbing ladder being arranged at a preset angle to the carrying mechanism; and a cargo handling mechanism located on the same side of the carrying mechanism and in the cargo work area, the cargo handling mechanism including a lifting ladder and a cargo basket, the lifting ladder being fixedly connected to the work platform and the carrying mechanism, and in the working state, the cargo basket being electrically driven by the lifting ladder and reciprocating along the first direction.

[0006] The high-altitude cargo lifting device provided in the first aspect of this application effectively solves the problems of high personnel safety risks, high FOUP transmission risks, and low operation efficiency in the prior art by dividing the high-altitude cargo lifting device into a pedestrian operation area and a cargo operation area, and adopting a partitioned design of a load-bearing mechanism, a step ladder mechanism, and a cargo handling mechanism.

[0007] In the stair mechanism, the climbing ladder and the supporting mechanism are arranged at a preset angle. Combined with the preset height difference between the working platform and the supporting mechanism, the workers can complete the climbing operation on a relatively stable support structure, avoiding the risk of center of gravity imbalance caused by the lack of guardrails in traditional A-frame ladders.

[0008] The cargo handling mechanism drives the cargo basket to move back and forth in the first direction via a lift, realizing automatic lifting and transportation of the FOUP and eliminating the risk of the FOUP slipping during manual transfer.

[0009] The physical separation design between the pedestrian operation area and the freight operation area not only ensures the safety of personnel operation, but also simplifies the operation that originally required multiple people to operate by two people and one person to maintain order through the linkage between the operation platform and the cargo basket. One person climbs to retrieve the goods and the other receives them on the ground, reducing labor costs.

[0010] In addition, the cargo handling mechanism uses electric drive instead of hydraulic system, avoiding the defects of oil pollution in cleanroom environment. At the same time, the fixed connection design between the elevator and the load-bearing mechanism avoids the dependence on battery for frequent start and stop, ensuring that the system can still maintain stability in the event of power failure or abnormal situation, thereby meeting the high reliability requirements of semiconductor manufacturing for cargo handling operations.

The second buffer block is located between the side panel and the retractable baffle, and the locking part is partially located in the receiving cavity and abuts against the retractable baffle to fix the retractable baffle.

[0013] According to any embodiment provided in the first aspect of this application, the retractable baffle includes three pieces, which enclose a positioning cavity, and the maximum compatible size of the positioning cavity is 0.5m*0.4m.

[0024] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0025] It should be noted that in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0026] Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0027] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] In the cleanroom environment of semiconductor manufacturing, the current practice for retrieving goods from heights when equipment such as overhead hoist vehicles / overhead hoist buffers (OHV / OHB) and vacuum carriers (VC) in automated material handling systems (AMHS) malfunctions is to use traditional A-frame ladders for manual climbing.

[0029] Using an A-frame ladder poses safety hazards. Workers must climb to a height of about 3 meters and, without effective support, use both hands to retrieve the standard container used for wafer transport, namely the Front Opening Unified Pod (FOUP), and then pass it to the receiving personnel on the ground. During the entire operation, the worker's center of gravity is very easy to lose balance. If they slip, it may not only cause personal injury, but may also cause the FOUP to fall, thereby damaging the wafers or even scrapping the entire batch.

[0030] In addition, to ensure basic safety, this operating mode requires at least four staff members to work together, including one person to retrieve the goods from the height, one person to hold the ladder steady, one person to receive the goods on the ground, and one person to maintain order on site. This results in high labor costs and complex coordination.

[0031] Even so, existing protective measures are still extremely limited, mainly relying on safety ropes and lacking active protection structures such as continuous guardrails or handrails, which cannot eliminate the risks of working at heights.

[0032] On the other hand, although there are already guardrail-type automatic lifting devices as alternatives in the engineering field, such as lifting operations by driving multiple cylinders through hydraulic or electric systems, these devices cannot be applied in semiconductor cleanroom scenarios.

[0033] The core reason is that hydraulic systems have the risk of oil leakage, and semiconductor manufacturing has extremely high requirements for environmental cleanliness. Any oil contamination can seriously affect the process yield. Therefore, such devices are usually limited to maintenance or engineering purposes in non-clean areas.

[0034] Meanwhile, existing aerial work platforms generally rely on battery power, which completely fails in the event of a power outage or depletion of power, failing to meet the reliability requirements for emergency cargo rescue.

[0035] More importantly, the frequent start-stop lifting operations not only consume a lot of battery energy, but also challenge the endurance of operators and may affect the "Quality Time" of FOUP, which is the time limit for the wafer to remain under specific environmental conditions.

[0036] In order to solve the above-mentioned technical problems and for technical considerations, this application provides a high-altitude cargo lifting device.

[0037] The following will combine Figures 1 to 3 The high-altitude cargo lifting device provided in the first aspect of this application will be further described in detail.

[0038] Figure 1 The overall structure of the high-altitude cargo lifting device provided in the first aspect embodiment of this application is shown.

[0039] Please see Figure 1 In the first aspect, the embodiments of this application provide a high-altitude cargo lifting device, which is divided into a pedestrian operation area 100a and a cargo operation area 100b. The high-altitude cargo lifting device also includes a load-bearing mechanism 10, a step ladder mechanism 20 and a cargo handling mechanism 30.

[0040] The stair mechanism 20 is located on one side of the support mechanism 10 and in the pedestrian work area 100a. The stair mechanism 20 includes a climbing ladder 21 and a work platform 22. The work platform 22 is at a preset height H away from the support mechanism 10 along the first direction X. The climbing ladder 21 overlaps with the work platform 22 and the support mechanism 10, and the climbing ladder 21 is arranged at a preset angle A with the support mechanism 10.

[0041] The cargo handling mechanism 30 is located on the same side of the carrying mechanism 10 and in the cargo operation area 100b, along with the step ladder mechanism 20. The cargo handling mechanism 30 includes a lift 31 and a cargo basket 32. The lift 31 is fixedly connected to the work platform 22 and the carrying mechanism 10. In the working state, the cargo basket 32 ​​is electrically driven by the lift 31 and moves back and forth along the first direction X.

[0042] The high-altitude cargo lifting device provided in the first aspect of this application effectively solves the problems of high personnel safety risks, high FOUP transmission risks, and low operation efficiency in the prior art by dividing the high-altitude cargo lifting device 100 into a pedestrian operation area 100a and a cargo operation area 100b, and adopting a partitioned design of a load-bearing mechanism 10, a step ladder mechanism 20, and a cargo handling mechanism 30.

[0043] In the step ladder mechanism 20, the climbing ladder 21 and the supporting mechanism 10 are arranged at a preset angle A. Combined with the preset height H of the working platform 22 and the supporting mechanism 10, the workers can complete the climbing operation on a relatively stable support structure, avoiding the risk of center of gravity imbalance caused by the traditional A-frame ladder without guardrails 23.

[0044] The cargo handling mechanism 30 drives the cargo basket 32 ​​to move back and forth along the first direction X via the elevator 31, realizing the automatic lifting and transportation of the FOUP and eliminating the risk of the FOUP slipping during manual transfer.

[0045] The physical isolation design between the pedestrian operation area 100a and the freight operation area 100b not only ensures the safety of personnel operation, but also simplifies the operation that originally required multiple people to operate to two people and one person to maintain order through the linkage and cooperation between the operation platform 22 and the cargo basket 32. One person climbs to pick up the goods and the other receives them on the ground, reducing labor costs.

[0046] In addition, the cargo handling mechanism 30 uses an electric drive instead of a hydraulic system, which avoids the defects of oil pollution in the cleanroom environment. At the same time, the fixed connection design between the elevator 31 and the load-bearing mechanism 10 avoids the dependence on batteries for frequent start and stop, ensuring that the system can still maintain stability in the event of power failure or abnormal conditions, thereby meeting the high reliability requirements of semiconductor manufacturing for cargo handling operations.

[0047] The supporting structure 10 serves as the basic support structure, with a stair mechanism 20 installed on one side. The stair mechanism 20 includes a climbing ladder 21 and a working platform 22. The working platform 22 and the supporting structure 10 are spaced at a preset height H along the first direction X. The climbing ladder 21 overlaps with the working platform 22 and the supporting structure 10, and the climbing ladder 21 and the supporting structure 10 are arranged at a preset angle A. This arrangement at the preset angle A allows workers to form a stable working surface with the support of the supporting structure 10 during climbing. Compared with the traditional A-frame ladder without fixed support, this reduces the risk of falls due to instability during high-altitude operations. Furthermore, the stair mechanism 20 can still be used normally when the power is off, further enhancing the stability of the high-altitude cargo lifting device.

[0048] Meanwhile, the preset height difference H-difference design of the work platform 22 provides workers with a standing operating space, further enhancing the operational stability during the operation.

[0049] In the cargo handling area 100b, the cargo handling mechanism 30 and the step ladder mechanism 20 are located on the same side of the carrying mechanism 10. The cargo handling mechanism 30 includes a lift 31 and a cargo basket 32. The lift 31 is fixedly connected to the work platform 22 and the carrying mechanism 10. The cargo basket 32 ​​is driven by the lift 31 to move back and forth along the first direction X.

[0050] The fixed connection between the elevator 31, the load-bearing mechanism 10, and the work platform 22 ensures that the elevator 31 can remain stable with the load-bearing mechanism 10 during operation, avoiding mechanical failures caused by structural loosening.

[0051] With the automatic lifting function of the cargo basket 32, the transportation of FOUPs achieves separation of people and goods. The operator only needs to load the FOUP into the cargo basket 32 ​​on the work platform 22 and lock it. Then, it can be safely transported to the ground receiving position via the elevator 31. The ground operator can unlock it and take it out, eliminating the risk of the FOUP slipping during the traditional manual transfer process.

[0052] For example, the climbing ladder 21 includes 6 steps, each step platform has a length and width of 0.2m*0.85m, and the working platform 22 has a length and width of 0.55m*0.85m and a maximum load capacity of 220kg, ensuring the convenience and stability of operators during the climbing and operation process.

[0053] For example, each step platform is also equipped with anti-slip mats to further enhance the safety of workers on the climbing ladder.

[0054] For example, the preset height H is 1.8m and the preset angle A is no more than 60°, further ensuring the convenience and stability of the operator during the climbing and operation process.

[0055] For example, the maximum lifting height of the elevator 31 is 2.4m, the lifting range of the cargo basket 32 ​​is controlled between 1m and 2.4m, and the maximum load capacity of the cargo basket 32 ​​is 50kg, which facilitates the operation personnel below to take the goods in the cargo basket 32.

[0056] For example, the overall maximum dimensions of the high-altitude cargo lifting device are 2.6m*2.9m*0.85m.

[0057] For example, the high-altitude cargo lifting device is made of aluminum alloy, achieving lightweight and cost control; steel structure is used at connection points and in locations with strict structural strength requirements to ensure structural strength and maximum load-bearing capacity. In addition, the use of conventional materials also has the advantages of easy replacement, easy maintenance and low repair costs.

[0058] Figure 2 An enlarged view of the cargo basket 32 ​​in the high-altitude cargo lifting device provided in the first aspect embodiment of this application is shown.

[0059] Please see Figure 2 In some embodiments, the cargo basket 32 ​​further includes a material box 323, at least one retractable baffle 324, and a first buffer block 321. The material box 323 includes a bottom plate 323a and a side plate 323b. The side plate 323b surrounds the edge of the bottom plate 323a to form a receiving cavity 323c. The first buffer block 321 and the retractable baffle 324 are located in the receiving cavity 323c. The first buffer block 321 is located on one side of the bottom plate 323a. The retractable baffle 324 is arranged parallel to the side plate 323b and reciprocates in a direction perpendicular to the wall of the side plate 323b.

[0060] In these embodiments, the material box 323 of the cargo basket 32 ​​is enclosed by the bottom plate 323a and the side plate 323b to form a receiving cavity 323c. Combined with the design of the first buffer block 321 and the retractable baffle 324, the fixation and protection effect of the FOUP is further enhanced.

[0061] The base plate 323a serves as the basic support surface, and together with the first buffer block 321 set on it, it can absorb the vertical impact force generated during the lifting process, reducing the risk of damage to the FOUP caused by vibration or collision.

[0062] The cavity 323c formed by the side plates 323b provides the FOUP with the maximum planar limiting space, preventing it from shifting laterally during transportation.

[0063] The retractable baffle 324 is set parallel to the side plate 323b and moves back and forth in a direction perpendicular to the wall of the side plate 323b. Its position can be adjusted according to the size of the FOUP. It achieves dynamic clamping by abutting against the side of the FOUP, which not only solves the compatibility problem of FOUPs of different specifications, but also replaces the traditional manual fixing method with mechanical limit, reducing the complexity of operation and enabling the cargo basket 32 ​​to adapt to various carrier forms. At the same time, through the energy absorption characteristics of the buffer block and the active limit function of the retractable baffle 324, multiple protections are achieved for the FOUP during the lifting process, which improves the safety and reliability of high-altitude cargo rescue, simplifies the operation process of operators, and reduces the dependence on operation precision.

[0064] For example, the retractable baffle 324 utilizes the elastic potential energy generated by spring compression to achieve reciprocating movement.

[0065] For example, the material of the first buffer block 321 is foamed electronic cross-linked polyethylene material.

[0066] Optionally, the material of the first buffer block 321 is polyurethane.

[0067] Please continue reading. Figure 2 In some embodiments, the cargo basket 32 ​​further includes a second buffer block 322 and a locking part 325 disposed through the side plate 323b. The second buffer block 322 is located between the side plate 323b and the retractable baffle 324, and the locking part 325 is partially located in the receiving cavity 323c and abuts against the retractable baffle 324 to fix the retractable baffle 324.

[0068] In these embodiments, the cargo basket 32 ​​further enhances the fixing effect of the retractable baffle 324 and the dynamic protection capability of the FOUP by adding a second buffer block 322 and a locking part 325 that penetrates the side plate 323b.

[0069] The second buffer block 322 is located between the side plate 323b and the retractable baffle 324, which makes up for the possible gap between the side plate 323b and the baffle. It absorbs the impact energy in the lateral direction through elastic filling. In particular, the inertial force generated at the moment the elevator 31 starts or stops can be effectively buffered to prevent the FOUP from being damaged by collision due to lateral shaking.

[0070] Meanwhile, the locking part 325, which is provided through the side plate 323b, extends into the receiving cavity 323c and abuts against the retractable baffle 324. The locking part 325 locks the retractable baffle 324 in a preset position by mechanical limiting, which not only solves the problem of displacement of the retractable baffle 324 due to vibration or external force during transportation, but also eliminates the potential loosening risk that may occur after the operator manually adjusts the baffle.

[0071] In addition, the second buffer block 322 and the locking part 325 also maintain the compatibility of the cargo basket 32 ​​with different FOUP sizes. Through the cooperation of the buffer material and the locking structure, it can be adapted to various specifications of vehicles, reducing the risk of fixation failure due to size differences, further simplifying the operation process and reducing the requirements for the operator's operating precision.

[0072] For example, the locking part 325 is a T-shaped handle lock. The operator can rotate and push the locking part 325 by turning the T-shaped handle, and the locking part 325 abuts against the retractable baffle 324.

[0073] Please continue reading. Figure 2 In some embodiments, the retractable baffle 324 includes three pieces, which together form a positioning cavity with a maximum compatible length and width of 0.5m*0.4m.

[0074] In these embodiments, at least three retractable baffles 324 can be used to enclose a positioning cavity within the material box 323 for placing FOUPs.

[0075] For example, a fixed baffle is arranged parallel to one side panel 323b inside the material box 323, and three retractable baffles 324 are arranged parallel to the remaining three side panels 323b. The three retractable baffles 324 can move flexibly and can be compatible with a variety of different FOUP sizes, such as the length and width of the existing common FOUP which is 0.44m*0.35m.

[0076] For example, the retractable baffle 324 inside the material box 323 includes a guide plate disposed on the side opposite to the bottom plate 323a of the material box 323, which further helps the operator to quickly place the FOUP into the designated position.

[0077] In some embodiments, the cargo handling mechanism 30 further includes a speed reducer for self-locking when it reverses.

[0078] In these embodiments, the speed reducer can reduce the rotational speed and increase the torque, thereby increasing the maximum load capacity of the cargo basket 32, while also achieving self-locking in case of loss of control in an emergency to prevent the cargo basket 32 ​​from falling uncontrollably.

[0079] For example, the reducer adopts a worm gear reducer, and the mechanical transmission structure of the worm and the worm can achieve mechanical self-locking when the worm and the worm reverse.

[0080] For example, the reducer adopts a dual worm gear reducer, providing multiple protections.

[0081] For example, the reducer's lead screw can also be connected to the shaft in a position convenient for the operator to operate by installing a manual crank, so that the lifting and lowering of the cargo basket 32 ​​can be controlled by hand with little effort; when not in use, the manual crank can be detached and stored, and a safety cap can be placed on the crank mounting point to prevent accidental contact with the shaft.

[0082] In some embodiments, the cargo handling mechanism 30 further includes a braking device for emergency stopping of the moving cargo basket 32.

[0083] In these embodiments, operators can also manually control the stop button to trigger the braking device, which can prevent the cargo basket 32 ​​from falling uncontrollably in an emergency, thus providing multiple layers of protection.

[0084] Figure 3 An enlarged view of the moving mechanism 40 and the supporting mechanism 50 in the high-altitude cargo lifting device provided in the first aspect embodiment of this application is shown.

[0085] Please see Figure 3 In some embodiments, the side of the carrying mechanism 10 away from the step ladder mechanism 20 and the cargo handling mechanism 30 also includes a moving mechanism 40 and a supporting mechanism 50.

[0086] In the working state, the support mechanism 50 extends along the first direction X toward the side opposite to the bearing mechanism 10, and the support mechanism 50 is used to fix the high-altitude cargo lifting device.

[0087] In the transfer state, the support mechanism 50 retracts, and the moving mechanism 40 is used to transfer the high-altitude cargo lifting device.

[0088] In these embodiments, a moving mechanism 40 and a supporting mechanism 50 are provided on the side of the carrying mechanism 10 away from the step ladder mechanism 20 and the cargo handling mechanism 30, so that the stability and portability of the device can be achieved through the cooperation of the two.

[0089] In the working state, the support mechanism 50 extends in the first direction X toward the direction away from the bearing mechanism 10 and provides additional support force through contact with the ground or the working platform 22, thereby enhancing the overall stability of the high-altitude cargo lifting device and preventing the risk of overturning due to center of gravity shift or external disturbance.

[0090] The extension action of the support mechanism 50 is achieved through mechanical locking, ensuring that it remains in a rigid and fixed state during operation.

[0091] In the transfer state, the support mechanism 50 retracts into the bearing mechanism 10, the moving mechanism 40 is activated, and the entire device is moved to the target position, improving the mobility of the equipment and enabling the high-altitude cargo lifting device to quickly respond to the needs of different work areas.

[0092] The linkage design of the moving mechanism 40 and the supporting mechanism 50 enables seamless switching between the two modes of fixed operation and regional transfer, which not only ensures safety during high-altitude operations, but also avoids the deployment inconvenience caused by the limited location of traditional fixed devices.

[0093] For example, the support mechanism 50 consists of six retractable support legs.

[0094] For example, at least two retractable support legs are fixed to mounting strips with adjustable opening angles. The mounting strips are symmetrically distributed and open to a set angle to provide more stable support for the high-altitude cargo lifting device.

[0095] For example, the moving mechanism 40 consists of four omnidirectional casters.

[0096] Please see Figure 1 In some embodiments, the high-altitude cargo lifting device also includes a counterweight assembly 60, which is located on the side of the bearing mechanism 10 where the step ladder mechanism 20 and the cargo handling mechanism 30 are arranged and in the pedestrian work area 100a.

[0097] In these embodiments, a counterweight assembly 60 is also arranged below the climbing ladder 21 to further enhance the stability of the high-altitude cargo rescue lifting device.

[0098] Please continue reading. Figure 1 In some embodiments, the counterweight assembly 60 includes a power supply assembly and a battery assembly, and the power supply assembly and the battery assembly are electrically connected to the elevator 31.

[0099] In these embodiments, the elevator 31 can be driven by two different power supply methods: plug-in power supply provided by the power supply component and energy storage power supply provided by the battery component. This further enhances the flexibility of the high-altitude cargo lifting device and meets the usage requirements under different working conditions.

[0100] For example, using a battery-powered system, the cargo basket 32 ​​can be raised and lowered approximately 180 times.

[0101] For example, both the work platform 22 and the support mechanism 10 are equipped with dual lifting control buttons, so that both the operator on the work platform 22 and the operator on the ground can control the elevator 31 through the dual lifting control buttons; when not in use, a safety cover can be used to cover it to prevent accidental activation.

[0102] Please continue reading. Figure 1 In some embodiments, the stair mechanism 20 also includes a guardrail 23 located on the side of the climbing ladder 21 and the work platform 22 away from the load-bearing mechanism 10, and the cargo handling mechanism 30 also includes a protective baffle 33 located on the side of the elevator 31 where the cargo basket 32 ​​is provided.

[0103] In these embodiments, the guardrail 23 on one side of the pedestrian operation area 100a and the protective barrier 33 on the other side of the freight operation area 100b further protect the operators.

[0104] The guardrail 23 effectively protects the operators climbing to the work platform 22, preventing accidental falls.

[0105] For example, the guardrail 23 on one side of the climbing ladder 21 has a height of approximately 0.6m, and the guardrail 23 on one side of the work platform 22 has a height of 0.6m to 1.2m, thus achieving effective protection for operators of different heights.

[0106] For example, the guardrail 23 has two adjustable heights. The fixed part and the telescopic part of the guardrail 23 are positioned and engaged by a button-type spring plunger and a positioning groove. The operator only needs to manually switch the button state to control the extension and retraction of the guardrail 23.

[0107] Optionally, the fixed part and the telescopic part of the guardrail 23 are separated and protected by a plastic sleeve to prevent the fixed part and the telescopic part of the guardrail 23 from directly contacting and rubbing against each other during extension and retraction, thus preventing damage.

[0108] For example, the guardrail 23 also includes a rotatable guardrail 23 behind the operator on the work platform 22, which can rotate 180° upwards to facilitate the operator's entry and exit from the work platform 22 and provide all-round protection for the operator when working.

[0109] For example, the guardrail 23 can also be set up to allow operators to attach safety ropes to the guardrail 23, providing further double safety protection.

[0110] The protective panel can effectively protect the operator who takes the FOUP from the cargo basket 32, and prevent personnel from being injured due to operator misoperation or accidental drop of goods during the transfer process. When the FOUP reaches the designated position, the operator can unlock the protective door and take the FOUP.

[0111] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
